Could Nicotine Stop Covid

0:231 year Ago
This video follows on from an OpEd I wrote for TrialSite News: Early in the pandemic researchers were scrambling to make sense of the data, much of this from China which has a high smoking prevalence. One review showed that current smokers were less likely to have an adverse COVID-19 outcome compared with former smokers. A groundbreaking pre-print from France in mid-2020 then examined if nicotine replacement therapy (NRT) given to smokers split into two groups (those with and without major smoking-related disease) would have an effect on hospitalization with COVID-19. In people without comorbidities from smoking-related diseases, nicotine replacement therapy was associated with a decreased risk of hospitalization. The ratio of NRT versus no NRT for patients hospitalized with COVID-19 was 151:496 while the ratio of death or intubation was 13:73. However, these trends did not carry over for patients having known smoking-related diseases. Continuing research then suggested that nicotine, not smoking, could offer some protection against COVID-19. There are even five clinical trials underway in France. They are investigating the potential protective effect of nicotine patches to prevent adverse outcomes like the need for mechanical ventilation or transfer to intensive care and even as a preventative. According to these studies are active or recruiting or show as complete, but as yet, no new results have been published. Since the coronavirus pandemic began, doctors and scientists have observed that daily active cigarette smokers are less likely to become severely infected or hospitalized despite the fact the virus targets the lungs. Reformed puffers aren't so lucky and are more likely to become ill due to smoke damaged respiratory or cardiovascular systems, or because of immune compromise. Ultimately, COVID-19 is an inflammatory syndrome illness. Current thinking is that the principal receptor allowing the SARS-CoV-2 virus to infect cells is through the angiotensin-converting enzyme 2 (ACE2) found in the lungs, small intestine, colon, kidney, brain and heart. However, there is some doubt this is the only way the virus causes infection since high ACE2 levels may be beneficial rather than harmful, especially in people with lung injury, like smokers. When lungs are infected by bacteria, fungi or viruses a strong inflammatory response occurs. Illness severity depends on lung macrophages which switch between pro-inflammatory and anti-inflammatory modes by releasing high levels of inflammatory cytokines. This signals other cells to challenge the infection and helps with healing. Severe COVID-19 symptoms and mortality are related to an over-responsive immune system leading to the cytokine storm effect. What if other receptors or activators control whether the coronavirus can successfully gain entry into cells? This paradox is explained by the nicotine hypothesis where the addition of this alkyloid drug exerts its protective effect via the nicotinic acetylcholine receptor (nAChR) by modulating ACE2 expression and preventing a hyperinflammatory response. By increasing ACE2 expression in cells, lung injury and kidney damage can be limited. Nicotine may also help reduce platelet aggregation and stop clot formation since it has known antioxidant and anti-inflammatory properties. Although no published clinical results are available at this time to supplement the earlier work, a review of over forty international studies shows clear differences between smoking history and non-severe and severe COVID illness; with smokers being more than twice as likely to suffer severe illness. But there are numerous contradictory studies from China, South Korea and India showing protection from SARS-CoV-2 infection from smoking. I asked Professor Dautzenberg about the importance of therapeutics like nicotine compared with vaccines and their role in public health messaging. He is of the view that the "vaccine is much more active but it's important to understand everything about COVID-19 including the interaction of nicotine with COVID". So even though we'll have to wait for the results from these trials, we all want to know whether nicotine might work as a preventative or to limit hospitalisation or severity. To this, Prof. Dautzenberg commented "the only practical recommendation is to offer complete nicotine substitution in all hospitalised COVID" patients. Based on the scientific research alone, repurposing already available and approved nicotine products like gum or patches could help restore the compromised function of the nicotinic cholinergic system under coronavirus attack. This could be a valuable, low-cost therapeutic option for treating COVID-19 by reducing inflammation and suppressing the cytokine storm. #nicotine #nicotinehypothesis #coronavirus

The Relationship Between Germs And Bed Linen

14:061 year Ago
We may think that our beds and bedding are cozy and comfortable, but they may not be as clean as we think. More often than not, there are a lot of germs lurking in and around them. These microorganisms are often shed from our bodies and find their way into our bedrooms where they become entrapped into the porous sheets, duvet, pillow, and even bedhead materials. And it’s not only a one-way transfer process. Once contaminated, the water vapor our bodies naturally give off can also transfer and provide the water source for these bacterial, fungal, and yeast cells to multiply. Germs are not only found in our bedrooms and bed linen but elsewhere in our homes. They’re everywhere - in the air and on surfaces - and in every building including hospitals. When these germs are transmitted from surfaces to the body this is called fomite transmission. This hand-to-mouth disease transmission from surfaces onto the fingertips is highly efficient showing 33% efficiency for both bacteria and viruses. A well-known study showed that in a hospital, even clean linen is a problem with about 55% of bed linen becoming contaminated before contact with a patient using the bed for the first time. Microbiologists measure contamination by pressing Petri plates onto areas of interest or swabbing over a known area. The index used is germs (or colony forming units) per centimetre squared, CFU/cm2. Clean linen has approximately 0.1 colony-forming units per square centimetre, while dirty linen has lots of microbes, up to 1 colony per centimeter square. However, staff uniforms and clothing are known to contain an even higher number of microbes of up to 2 colony-forming units per centimeter square. Nearly 60% of the identified Species of these disease-causing bacteria could be opportunistic pathogens and a risk for people with weakened immune systems. This is really important and the latest research about immune status shows across nearly 27,000 people diagnosed with COVID-19, those persons most at risk for serious illness have specific quantities of a white blood cell called lymphocytes. We already know that lymphocytes help your body fight infections and that lymphocyte levels determine inflammation status. This paper, then shows that low to very low leucocyte levels predict COVID severe outcomes; while the reverse is also true, and those persons with high levels of leucocytes may develop the cytokine storm phenomenon which also has worse outcomes. A study by the Commonwealth Scientific and Industrial Research Organization (CSIRO), an Australian government agency responsible for scientific research, looked at how long the virus remained infectious on six common surfaces, namely cotton, glass, steel, vinyl and paper and polymer banknotes. Importantly, there was a clear correlation between temperature and virus recovery. For cloth, at 20°C, the virus was infectious up to day 14; at 30°C up to 3 days; while at 40°C, the virus was only infective for 16hrs. The point here is that the virus depends largely on temperature for survival. The cooler the temperature, the longer the virus remains infectious on different materials. Therefore, the importance of washing machine temperature cannot be underestimated. Lower temperature washing cycles can only be compensated for by extending the wash cycle time for much longer periods. The importance of heat therefore cannot be denied and I recommend a temperature/cycle time optimum of 60°C for at least 45minutes for the main wash cycle.

Watch Out: How Fungi Are Taking Over Nail Salons And What To Do About It

5:021 year Ago
A nail salon offers nail care services such as manicures, pedicures and nail enhancements. One-stop nail salons provide facial treatments, waxing and skin care in addition to nail services. The global nail care market is projected to reach $11.6 billion by 2027. Even during the COVID-19 crisis, the global nail care market was estimated at $9.9 billion in 2020 but the importance of respiratory health in the nail care sector is rarely discussed. Nail salon workers operate in a poorly ventilated and potentially hazardous work environment with negative health consequences. Emerging research is shining a light on foot and nail dust and the presence of fungi in both fungal-infected as well as healthy-looking nails. This research shows that while the majority of healthy people can tolerate inhaled fungi, the immune systems of older, potentially immunocompromised and allergy-prone individuals often react to this foot and nail dust through the inflammatory TH2 pathway. This can lead to an overproduction of mucus, bronchoconstriction and, in severe cases, lung tissue damage. A June 2021 study published in the Journal of the American Podiatric Medical Association shows that exposure to dust, including fungi by nail technicians and foot specialists, is a very real but hidden problem. These workers often complain of allergies and other adverse respiratory symptoms at a much higher rate than the average population. From the early 2000s, according to research, podiatrists, especially in the United Kingdom, exhibit four times the national prevalence of asthma, with nearly 40% of podiatrists who were surveyed reporting experiencing allergy. The most common nail condition is called onychomycosis and is known to affect 5.5% of the global population. Symptoms include thickened yellowed nails and a crumbling nail bed. Individuals with onychomycosis may turn to nail technicians and podiatrists to trim and file down their nails. This may also be used to improve the uptake of oral or topical antifungals. The latest research shows that podiatrists have a higher prevalence of antibodies versus the general population to the fungus Trichophyton rubrum, which is the most common fungal microorganism linked with onychomycosis. Interestingly, podiatrists are also more likely than the general population to have Aspergillus fumigatus in their nostrils. This is also a common cause of onychomycosis. The research reviewed other studies which showed that, in Australian podiatry survey, nail samples from medical patients were all positive for fungi, including dermatophytes at 86%, Aspergillus species at 94%, and Scopulariopsis at 40%. Candida were also isolated from the air in podiatrists’ offices. The reason this happens is due to the drilling and grinding of the nail and skin which creates aerosols, which can remain in the air from minutes to hours after completion of any procedure performed on the nails. It’s therefore important that we understand the risks posed by particulate matter dust and fungi. It's known that inhaling fine particulate matter on a continuous basis can cause adverse health reactions, including lung inflammation in older or immunocompromised persons, and that these small particles can be deposited deep within the lungs. Note also that fungal spores are one to two microns in size generally, and also have the potential to reach deep into the lungs when inhaled. It's reasonably well known too that fungi can cause asthma, which manifests as a bronchial constriction with airflow obstruction. Fungal sensitization, in contrast, involves an immune response without inflammation but with elevated fungal-specific IgE or an immunoglobulin allergic response. Other symptoms include fungal allergy, which does involve inflammation, with associated pulmonary tissue damage. What then is the best way to reduce lung exposure to dust and fungi in nail salons? The best approach is to ensure that all personnel wear, at least, a medical-grade mask, and preferably a properly fitted n-95 mask. It's important to make sure that they fit well to reduce particle inflow. Proper maintenance of personal protective equipment, drill bits, and the use of dust suppression systems to filter the air are all effective approaches to reducing the exposure risk for those undertaking work to the nail bed as well as other clients and staff in the nearby office vicinity. While most healthy immune-strong foot and nail care professionals will not experience respiratory problems, it’s absolutely necessary for persons who are predisposed to allergies or who have compromised immune systems to take these simple but highly-effective safety precautions to reduce the risks associated with inhaling fungi and chemicals in nail or skin dust.

The Relationship Between Indoor Air Quality And Happiness

18:572 years Ago
Studies have shown that people are healthier, more comfortable and more productive in structures with good indoor air quality (IAQ). Be that as it may, I've had a first-hand experience as an indoor air quality and mould inspection expert not only about the huge impact of moulds and water damage on people’s property but also the emotional distress these things can cause them. According to studies, there exists a huge relationship between emotional wellbeing and particulate matter pollution, and a very strong numerical relationship between mould spore counts, the presence of water damage, including hidden mould, and measures of particulate matter in the PM 2.5 and PM 10 size range. And as the concentration of PM 2.5 particles in the air increases, levels of happiness decrease. As the concentration of PM 2.5 pollutants increases, levels of tiredness, stress and sadness all increase. Read the blog here: REFERENCES: Li M, Ferreira S, Smith TA, Zhang X.

Disease Prevention – Is This The Future of Healthcare – Clubhouse Conversation Recap

17:172 years Ago
Prevention, they say, is better than cure. And that forms the basis of preventive medicine, a proactive approach aimed at getting ahead of the potential causes of diseases by promoting healthy behaviours and screening for diseases with the aim to keep people from becoming sick in the first place rather than treating diseases when they eventually occur. In this week on The Mould Show I dive into the emerging social media, audio-only platform called Clubhouse. Here you'll find a large range of healthcare, wellness and medicine focussed groups (as well as many others) that are relevant to biotoxin illness. After listening in, making some rooms, creating a club or two and talking into these rooms, I'm reviewing some of the key takeaways around the future of healthcare. Synopsis: Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices and are dynamic processes which begin before individuals realize they are affected.

Top 7 Mast Cell Activation Syndrome Triggers You Should Avoid

16:112 years Ago
Mast Cell Activation Syndrome (MCAS) is a very serious, often overlooked condition. About one in four people with the disease cannot work or participate in normal day-to-day activities. It is a disease that affects people of all ages or gender, but one funny thing about it is that it is often unrecognized and possibly remains undiagnosed in many cases. MCAS is a group of diseases involving the immune system. When the triggers occur, antigens are raised inside the body, which might result in itchiness, for example. But this also leads to a histamine cascade, which causes contraction of the respiratory vessels. Then blood vessels dilate and result in gastric acid secretion. Many people with MCAS can have very serious life-threatening reactions such as anaphylaxis. Typical symptoms include itching, headaches, brain fog, fatigue, heart palpitations, hives, shortness of breath, gastrointestinal problems, wheezing, low blood pressure, anxiety, and, very typically, flushing or swelling, which appears on the face or body. According to the American Academy of Allergy Asthma & Immunology, Mast Cell Activation Syndrome is a condition in which the patient experiences repeated episodes of the symptoms of anaphylaxis – allergic symptoms such as hives, swelling, low blood pressure, difficulty breathing, and severe diarrhea. High levels of mast cell mediators are released during those episodes. For these reasons, it is therefore important that you are very much aware of the top seven underlying factors that can contribute to Mast Cell Activation Syndrome and avoid them completely so you can live a healthier, happier life.

What everyone must know about early life allergen exposure

14:232 years Ago
An allergen is usually a harmless substance capable of triggering a response that starts in the immune system and results in an allergic reaction, like sneezing or itching. How then does the indoor living environment affect children? A recent study looked at early life exposure, including prenatal exposure and how this can be linked to behavioural changes, growth delay and neuroimmune complications; and made some startling revelations. The researchers found that children exposed to allergens, including water damage, and mould in the womb for up to two years may display growth delay, allergic rhinitis, asthma, dermatitis, motor problems and speech delay. Note that all the children were experiencing seizures! Learn what the doctors recommend and what you need to know.

10 Reasons Your Relationship With Hypersensitivity Is Toxic

20:302 years Ago
Allergens are all around us. It seems like a fairly straightforward concept, though how they find their way to us can be extremely surprising. Take for example, animal allergens. If you learned that your child had a dog allergy, what steps would you take to avoid issues for them? The most common response to this would likely be some variation of not having a pet dog and limiting visits to places where dogs live. After all, kids spend most of their time at school or at home so you may think there is little risk of exposure in these controlled environments. This is, however, not the case. Studies have found that children will be exposed to dog and cat allergens just by attending school. During a 1998 study conducted in a Swedish school it was discovered that allergens were present on the clothes worn by all pet owning students. Despite preventative measures we may take against them, allergens still find a way to infiltrate places we believe are safe. Allergens are definitely a bit more complex than we may give them credit for. That is because allergens truly are everywhere. But, what exactly is an allergen? Typically, an allergen is either a protein or a glycoprotein. The most common of these can be found in pollen, fungus, dust mites, and animal material. When these enter your body, either through inhaling or ingesting them, they trigger an immune response. This immune response is what causes common allergic reactions like coughing and sneezing, as well as more serious reactions like anaphylaxis. As you know, however, there are far more allergies than the ones listed above. Bugs like cockroaches are a massive cause of allergens, many people have severe reactions to bee stings, and medications that can save one person’s life may kill another who takes it. It is truly fascinating how something so simple can cause such a wide array of reactions in different subjects. To summarize, there is no truly effective way to outrun allergens. They are a part of our world and will always be there. Luckily, through medical science advances, we have devised a number of ways to manage and deal with their effects as we continue our research on the topic. REFERENCES: Lei, D. and Grammer, L., 2019.

5 ways to reduce sneezing and dominate dust in your home video

7:582 years Ago
COVID-19 has reshaped how we think about public health and the practical steps we take every day to keep ourselves safe and healthy. Today more than ever, we share a heightened responsibility surrounding our environmental hygiene, as well as the potential harm that poor cleaning habits can cause. Something we encounter every day is dust. It’s synonymous with being untidy, old, and causing us to sneeze. But perhaps in our post-COVID world, we will see dust a little differently. Dust is an organic material, a combination of microbial vegetable or animal materials. Often, household dust is comprised of skin cells from human inhabitants and pets. As it is biological, dust can contain viruses, bacteria, fungi, algae, insects, mites, and even antibiotics. Moreover, dust contributes to bioaerosols, which when disturbed, become airborne and can cause respiratory issues. This forms part of the background bioburden to the home and the subsequent risks from exposure. The most common allergic reaction to dust is sneezing, however, this can develop into a condition called allergic rhinitis. This is an inflammatory disease of the nasal mucosa and can cause further nasal congestion as well as itchiness or irritation, as well as redness of the eyes and inflammation and discharge from the nose. Allergic rhinitis is one of the most common atopic diseases, and depending on where you live, affects between 10% and 60% of the population. Of these cases, the most common cause is from household dust allergens. Allergic rhinitis caused by dust can lead to workday losses in adults and school day losses and learning disabilities in children. People who suffer from allergic rhinitis report feeling tired and can also report feeling miserable because of their nasal symptoms. So, what steps can we all take? A great method to combat dust is to use microfiber cloths rather than cotton or other woven-style cleaning materials. Microfiber works so well because it has a high density of cleaning strands, with the increased surface area offering a better level of cleaning. Additionally, disposable wipes are a great way to get dust under control. Some contain alcohol, detergents, antimicrobial solutions or are simply damp. They work through a combination of both physically moving material, as well as the added effect of any detergent of alcohol within the wipe. Even with the addition of a cleaning solution, there is still a risk of cross-contamination from using the same wipe on multiple surfaces, therefore it is vital to adhere to the ‘one wipe, one surface’ rule. Thirdly, it is important to understand that fungal contamination of buildings is known to be worse in winter while the overall levels of bacteria tend to decrease. Therefore, cleaning of surfaces that potentially become water prone, or show condensation, should be cleaned more frequently during winter. The fourth important point is that research suggests that where you live has an impact on your experience of allergic symptoms. For example, if you live in an urban area, your risk of allergic rhinitis is four times higher compared to those who live in rural areas, and your asthma risk is eight times higher, primarily due to traffic air pollution. If you find you’re a prevalent sneezer, and you can’t escape to the countryside, then pay close attention to hard-to clean areas like the tops of pictures or mirrors on walls, the tops of doorframes, the tops of shelving. Consider testing these areas with tape lifts if you want an objective measure of the settled dust bioburden. Finally, it’s worth knowing that microfibers containing sporicidal disinfectants and detergent is more effective at reducing microbes that remain on surfaces in comparison to microfiber towels that are just made damp with water and used to clean. Many gym or workout towels are made of microfibre but may not be as effective as you imagine. Wiping down gym equipment with a damp microfibre towel will not be as effective as using microfiber cleaning cloths containing sporicidal disinfectants and detergent. To summarise, it’s important to understand the difference between cleaning something and thoroughly disinfecting it - an object or surface may appear clean to the eye, but could be havering dust, pathogens or other microbial matter. As life under COVID has taught us, disinfecting things we come into contact with is an important step to keeping us healthy, so perhaps it’s time we thought the same way about dust. #microfibre #dust #cleaning

Why Climate Change Could Cost You Your Cappuccino

13:402 years Ago
“It's often said that a bad day with coffee is better than a good day without.” A fair statement, no? If you asked any of the drinkers of the 2.25 billion cups of coffee drunk daily, they’d probably all give you a similar answer. Some research suggests that coffee may even have some positive health benefits. But this uniquity of caffeine consumption raises some serious questions about the damaging effects our coffee habits are having on the planet. Let’s begin on a positive note: A research paper from April 2020 reviewed randomized clinical trials and other observational studies to show that coffee can reduce the risk of type two diabetes, cardiovascular disease, as well as several forms of cancer. So perhaps you are inadvertently protecting yourself from some harmful conditions each time you pop into your local cafe. Sadly, the positivity ends there. Our growing demand for coffee presents us with a multitude of issues, many of which require urgent action. The first of which is that we will soon be running out of suitable areas to farm coffee. By 2050, it is estimated that up to 50% of the land currently used for growing coffee will be lost to climate change. To compensate for this, farmers and roasteries are trying to cultivate as much coffee as possible and have adopted destructive practices that can harm both the coffee plants and the surrounding ecosystem. Coffee is particularly vulnerable to a wide range of pests, including bacterial and fungal diseases, and as such, growers use an array of pesticides to reduce the number of wasted coffee plants. However, these chemicals can seep into local water sources and pollute the wider area. This is not the only pressing issue. In the future, growers will have to adapt because climate change will inadvertently alter the types of fungi that manifest within their plants. This is because different types of fungi can grow within coffee plants at differing temperatures, and as we see a global increase in temperature, the types of fungal infection that coffee plants are susceptible to will change. It is likely that there will be an increase in mycotoxin production, which is capable of causing a range of diseases. Mycotoxins are already commonly found in coffee, but because they can be potentially harmful they are regulated. Their prevalence in coffee is dependant on the climate in which the beans are grown. Ochratoxin content is very high in coffee from Turkey, Philippines and France but low in coffee from Ethiopia and, Thailand and Japan. And this is why good farming practices such as proper drying of crops can help prevent mycotoxin contamination after harvest and reduce economic losses. REFERENCES: Mycotoxin contamination is treatable, and there are a range of agents that can bind and neutralize mycotoxins in the gastrointestinal tract, including activated carbon and clay. But it is, of course, better to be proactive in dealing with this problem. Adhikari M, Isaac EL, Paterson RRM, Maslin MA.

Can the mould in blue cheese be as harmful as mould in the house?

12:572 years Ago
When we see mould on our food our immediate reaction is to throw it away. To us, it is an indication that the food has turned bad, and we assume that food would not taste the same because fermentation has started. Along with this, we begin to question the texture, aroma and appearance of the food. However, we sometimes see mould as a delicious component of some of our favourite indulgences. Mould is, of course, responsible for the speckles within blue cheese and it’s characteristic saltiness and sharpness. It is caused by the cultivation of Penicillium roqueforti and Penicillium glaucum during the oxygenation of the cheese. Mould can be seriously harmful to us, especially to those who suffer from an allergy to it, so is there a heightened risk from eating blue cheese? We know that allergies and immune responses are influenced by our environmental exposures in our early life. In fact, eating cheese at 18 months of age shows a protective effect especially for eczema and food allergies. This is because our bodies develop an immune response to the cultures within the cheese which it carries on into later life. So, what causes the body to react to an allergy? There are two immune defence mechanisms, triggered by immunoglobulin reactions termed IgG and IgE. We all have IgG antibodies, and most food intolerances are caused by IgG. The reaction itself occurs sometime after ingesting the foodstuff, and reactions are often inflammatory. Over time, our bodies can sometimes overcome the allergy response or reduce its intensity. IgE, on the other hand, is more severe. They usually exist for a person’s entire life and symptoms often appear within seconds. They may include severe swelling, breathing difficulties, rashes, itching, and in severe cases and anaphylactic shock. But can blue cheese trigger a severe allergic response? There are reported cases of people suffering from sinusitis to the blue cheese fungus. Interestingly there are case studies of workers in cheese factories showing a hypersensitivity pneumonitis reaction, suggesting that their increased exposure results in a heightened immune response. The moulds within blue cheese are forms of Penicillin, which is a common allergen. In the United Kingdom, 2.7 million people report or self-report a penicillin allergy. However, this is incorrect in up to 95% of cases. Furthermore, there is a shortage of trained allergists, resulting in confusion as to whether or not a person’s allergy is an IgG or IgE reaction. This results in misdiagnoses, which has further complications in the prescription of antibiotics. Nevertheless, a true allergy to penicillin can result in a rash in over 50% of people, with 7% experience blistering skin or peeling. Additionally, 8% have difficulty breathing, 20% have a swelling reaction and 18% feel sick. Only 5% have the most serious and harmful anaphylaxis response. So, is a reaction to mould growing in the house the same as a reaction to blue cheese? IgG sensitivity to Aspergillus fumigatus, or mould that can be found growing in the house or on food, is different from IgE sensitivity to penicillin. So, if you feel that the mould in your house caused by damp or flooding is causing your body to have an adverse reaction, then it’s unlikely that he blue cheese in your fridge is going to cause you harm. The allergies are caused by different moulds, and so you’d be very unlucky to be affected by both. Even so, it’s more likely that you’ll have an IgG reaction, rather than the more harmful IgE. However, if you have been diagnosed with an IgE reaction to penicillin, then it is plausible that the penicillin growths within blue cheese could cause you harm.

Is mould the cause of your sleep problems?

10:272 years Ago
Sometimes, it seems like the hardest thing in the world to do is to get to sleep. Be it struggling to drift off, tossing and turning in the early hours or waking up too early and not being able to get any more shuteye - it’s something we’ve all had to deal with at one point or another. George Clooney blames his insomnia on a racing mind, helped only by going to sleep with the TV on, whilst Lady Gaga’s fibromyalgia and PTSD are both conditions known to negatively affect a person’s sleep. On the other hand, Rihanna’s reported ‘3 to 4 hours of sleep’ is self-inflicted, with the popstar admitting to binge-watching TV late at night. A 2016 Centre for Disease Control report concluded that sleep problems, including insomnia, sharply increases the risk of heart attacks, cancer, and obesity. Moreover, insomniacs are far more likely to suffer from mental health issues like depression as well as being linked to all major psychological disorders. But could mould be meddling with your sleep, and potentially causing you serious health concerns? One study set out to investigate whether exposure to dampness and mould could induce sleep disturbances, and their findings suggest that it could be far more common than you think. The researchers gave 11,318, adults in northern Europe a postal questionnaire and followed them up between 1990 and 2010, recording their sleep anomalies and any potential problems. The scientists defined a sleep problem being prevalent if it occurred three times a week. They found that the four most commonly reported types of sleep disturbances were: difficulty getting to sleep, difficulty staying asleep, early morning awakening and general insomnia symptoms like snoring, and excessive daytime sleepiness. They also recorded information on respiratory health and home and work environments, to see if there was any correlation between the participants’ exposure to mould and their sleep problems. The results found that floor dampness, visible mould and mould odour would all contribute to the four major sleep problems. Within the study, one in three of the subjects developed insomnia, over the 10-year period, one-quarter of the subjects suffered from interrupted sleep and 15% of them starting snoring. One of the primary causes of dampness in the home and subsequent mould growth is floor dampness from concrete flooring. This arises during the construction of new homes when the flooring is undergoing the curing process. Emissions of toxic chemicals from waterlogged concrete has been linked to asthma. The report concludes its findings, saying: “the observed association between damp and mouldy buildings and the onset of sleep disturbances is a novel finding.” and emphasizes the importance of reducing indoor dampness and mould at home, to reduce the risk of impaired sleep quality, and any potential health consequences. So, does this mean that your sleep problems are down to mould in your house? The science is still fresh, and there is plenty more for researchers to investigate, but the results of this study indicate that it could be a possibility. Or perhaps you’re like Rihanna, and simply enjoy a little bit too much late-night TV. REFERENCES: Schutte-Rodin S, Broch L, Buysse D, Dorsey C, Sateia M.

What is that mould smell, and is it worth $5m?

10:272 years Ago
We all know the smell. That damp, pungent aroma that lingers in the air, it can be earthy, meaty and musty, like sodden socks or rotten wood. The odour has connotations of decrepit squalor, yet it is something we’ve all had to deal with at one point or another, so, just what is that smell, and is it worth a $5million lawsuit? Megan Fox, actress and model, amongst other things, is suing a range of lawyers and agents after buying a Malibu property which allegedly had a mould problem. Miss Fox claims that the mould on the property, caused by damp, was causing her “chronic headaches” for which she received “holistic treatment.” So it would appear that even the Hollywood elite are all too familiar with the pervasive aroma of mould, but just what is it that gives it that distinct scent? READ MORE HERE: The smell released from mould, or more generally fungi, are called VOCs (Volatile Organic Compounds). The’s VOCs can be pleasant, such as the odour emitted from wine or beer, while others are repulsive, such as the stink of sewage. The growing field of research into the volatilome sees scientists using chemical sensors to take a snapshot of the aroma profile to pinpoint exactly what is causing the specific aroma. So far over 300 VOCs have been identified. Despite being on the cutting edge of today’s research, smell has been used as far back as Ancient Greek physician Hippocrates to identify a patient’s ailments. But is the smell of mould as bad as we think or are the connotations we apply to it a factor in our disdain towards the scent? Shakespeare explores this in Romeo & Juliet, saying: “A rose by any other name would smell as sweet”, yet scientists have found that the name of a smell has a direct impact on how we react to it. They tested this by labelling a smell with either a pleasant name, such as countryside farm, or an unpleasant one, like hospital disinfectant. They found that the positive name made a pleasant smell more appealing, and conversely, less pleasant odours were experienced more repulsively when they were associated with negative names. One can only guess at how Megan Fox would react to the smell of mould in her $3.3million Malibu mansion. So is the mould in Megan’s house causing her to become unwell? It could well be. mVOC’s (Microbial Volatile Organic Compounds) are products of microbial metabolism, and can be found in common household mould. People who are exposed to mVOCs complain of headaches, dizziness, fatigue, and asthma-like symptoms - exactly what Megan Fox has described as her experience in her recent lawsuit. But it doesn’t necessarily mean that the smell of mould means you’re being exposed to something potentially harmful, although that doesn’t mean there isn’t a chance. Mould smell indicates microbial growth which needs to be minimized to prevent property damage and unwanted exposure. But the science is increasingly showing us that these mVOCs are definitely connected with microbial activity and could be used to localize hidden mould, and potentially reduce the risk of someone becoming unwell. So, is the mould in your house worth a $5million lawsuit? If you’re Megan Fox, it could well be. The trial is ongoing, but perhaps a more thorough look around the property, and a good sense of smell, would have altered her to the dangers. REFERENCES: Inamdar AA, Morath S, Bennett JW.

The Hidden Dangers In Your Pillows You Need To Know About

9:492 years Ago
After a tiresome day, there is nothing better than crawling into bed and laying your head down onto a soft, comforting pillow. But before you drift off into the sweetest of dreams, take a moment to think about the hidden dangers lurking within your pillow. It could turn out to be your worst nightmare... A 2006 study looked into the fungi living in pillows, and they discovered that the most common three fungi were: Aspergillus fumigatus, Aureobasidium pullulans and a yeast, called Rhodotorula. What’s frightening is that Aspergillus fumigatus, the most common fungus found in the pillows, is known to have implications for patients who have respiratory disease, especially those individuals suffering from asthma and sinusitis. The study went further, discovering that fungi were more prolific in synthetic fibres than natural ones. Over the past 30 years, our bedding buying habits have changed from feather and flock pillows, sheets and blankets to mainly polyester pillows and quilts. This means that we are being exposed to more of this potentially harmful fungus and that our pillows aren’t as hygienic as we think. For people living with Chronic Obstructive Pulmonary Disease (COPD), a respiratory illness that affects 400,000 people in Oceania, the threat from this harmful fungus is very real. A recently published study found that up to 4% of COPD sufferers will develop infectious aspergillus, which has a startling mortality rate of 40-70%. This means that in any one year, approximately 7000 people die prematurely from invasive aspergillosis. And the most common fungus that causes invasive aspergillosis is Aspergillus fumigatus, the same fungi that is the most commonly found in pillows. Even for those who don’t suffer from COPD, there is still cause for concern from invasive aspergillus. More than ever, people are buying pillows that are branded as being “allergy friendly” and these are often made from buckwheat, but contrary to their allergy friendly claims, they can sometimes be the cause of someone’s reaction. As well as being a hotbed for aspergillosis, buckwheat has been a known allergen since 1909. A report from 2003 outlines the case of a 24 year old man in the US who went to his doctor reporting that he had been suffering from a worsening cough for the past three months, eventually becoming asthmatic. Any kind of medication prescribed to him was ineffective, yet the patient noted that anytime he spent time away from home his symptoms would improve, only to worsen when he returned. This led the doctors to test for any allergies the patient may be suffering from, and the results showed that he was suffering from a strong allergic reaction to both his buckwheat pillow as well as the aspergillus fungi growing inside of it. After removing both buckwheat pillows from his apartment, his cough and other symptoms completely resolved within four days. So how can you protect yourself from potentially harmful and hidden microbes in your pillows? One way would be to use a pillow protector to limit the physical contact you may be having with anything harmful within the pillow. Additionally, replacing your pillows more frequently will reduce the amount of harmful Aspergillus fumigatus you’re being exposed to. Moreover, being aware of what your pillows are made from will help you better understand the potential risks you are living with. If you use a synthetic or buckwheat pillow, it may be worth looking into replacing them with a natural feather pillow, which has fewer porous holes, therefore reducing contamination. Perhaps most important of all is simply being aware of the risks of infectious aspergillosis on susceptible people. Taking these simple precautions can help reduce the rate of premature deaths from infectious aspergillosis in the community. REFERENCES: Hammond EE, McDonald CS, Vestbo J, Denning DW.

How a Keto diet could protect you from dementia by altering your gut fungi

7:202 years Ago
Breakthrough research out this past week shows that the gut mycobiome has a big influence on brain function. Researchers have discovered that the Ketogenic diet can be used to manipulate the gut microflora and that certain fungi are linked with mild cognitive impairment. The Keto diet was compared against participants who ate a diet endorsed by the American Heart Association diet. REFERENCES: Nagpal, R., Neth, B., Wang, S., Mishra, S., Craft, S., & Yadav, H. (2020).

How fungus in the lungs can be used to predict respiratory distress

9:302 years Ago
The COVID pandemic has shone a lens on the issue of mechanical ventilators. No one wants to get that sick that ventilation is required just to have a chance at staying alive. In turn, what if there was a way to predict who would have a severe lung disease response or go on to suffer from acute respiratory distress syndrome (ADRS) and who wouldn't? Well, some clever scientists have just discovered why some people show a high level of inflammation and seem to go on and suffer with ADRS. In this LiveStream, I'm going to review this exciting breakthrough recently presented by the European Respiratory Society this week on Monday. Using next-generation sequencing, they were able to work out that the diversity of the lung fungal microflora (the mycobiome) predicted not only inflammation but detected the risk for which groups of people would have more severe lung disease. I'll even tell you the biomarker they tracked. So, what does this mean for you...well, if you have a predisposition to lung disease, then you'll want to tune in and find out why having a more diverse lung fungal mycobiome is better than lungs that show a dominance of one particular fungus. Tune into the Livestream to find out which fungus is the worst to have growing inside.

What Science Is Telling Us About COVID-19 and Long Haulers

9:522 years Ago
It’s one thing to get COVID but another to not get better! Long term symptoms, delayed recovery. What’s going on? This is something that’s beginning to be actively researched in the scientific community. It’s called Long Covid and people are suffering ‘long’ after the first classic Covid signs like fever or a positive test result. Those individuals who don’t fully recover are calling themselves ‘Long Haulers’. In this week's Livestream I’m going to cover what we know about post covid recovery, discuss what’s emerging in the literature about long covid and what some innovative social media data analysis reveals. I’ll also be discussing the link with chronic fatigue and mould hypersensitivity.

How an common anti-fungal drug could help stop brain disease

30:582 years Ago
Without medical breakthroughs, more than 6.4M Australians will be diagnosed with dementia in the next 40 years at a cost of more than $1 trillion. This week I want to discuss several exciting publications that have appeared in the research literature in 2020. It’s not just dementia, other diseases like Alzheimer’s, multiple sclerosis, Parkinson’s, stroke, and even depression are increasingly being linked to something called mitochondrial dysfunction. The literature shows that 2 approaches called: methylene blue and photobiomodulation might be very effective. But why? This issue of mitochondria and its’ link with inflammatory processes has been known for some time. Especially, with respect to how fungal pathogens and environmental fungi seem to induce similar mitochondrial dysfunction in humans. I will look at what’s known about this and then review a paper from 2020 showing that fungi have been found in the brains of people with Parkinson’s disease. This has been termed ‘polymicrobial invasion’ and suggests that some brain disorders are catalyzed by infections. The main paper I want to focus on as part of this Livestream came out on August 14th, 2020, and shows that brain inflammation, cytokine expression, and memory can be actively modulated with a common anti-fungal drug. This is breakthrough research and suggests this treatment could offer real relief in the near term. Join me on the Livestream or on the Podcast to find out which drug offers this potential microbiological benefit and what evidence supports this claim. REFERENCES: Mudarri D, Fisk WJ.

Facts About Black Mould and Fungal Sinusitis

Black mould is a common term used to describe home infestations with mould. It’s use is linked with an expectation of toxicity. In this week's Livestream, I report on the first case of Black mould sinusitis and how this was linked with immunocompromised status. Did you know that 17% of insurance claims at a major Australian insurer were water damage related? Did you know that in the USA, approximately 3.6% of the population are immunocompromised? Do you see a pattern here? Damp housing + immune compromise = opportunity for Black mould and other moulds to become BIG problems!

The papers I want to review in todays Livestream demonstrate that oral antiseptics like povidine-iodine are effective at inactivating the coronavirus. The effect works at a variety of concentrations after 60 seconds contact time. The research papers show this works as oral and nasal rinses. This is an important show - since these papers might help you or a loved one. Of course, speak to your medical doctor or other health care practitioner - but from an infection control perspective, these research results are very persuasive. Use masks and consider adopting the scientific results detailed in these papers into your own harm minimisation strategy during the pandemic. This is not an alternative to testing nor accessing your medical doctor if you have any symptoms that could be Covid-related, but this common antiseptic could help and that’s the point of today’s Livestream.

The Ugly Truth About Multiple Chemical Sensitivity, Dampness and Mould

25:182 years Ago
This week I want to discuss something called: Dampness and mould hypersensitivity syndrome (DMHS) and how this is related to exposure to the indoor air dampness microbiota (DM). There have been two papers published in the last 6 months that demonstrate in two different workplaces (Hospital workers and Police officers) how their respective buildings that had long-term water damage and mould were associated with very different symptoms when compared to a control group of people who hadn't been exposed to the water damaged buildings. These results should help anyone who is (possibly) having trouble explaining to others about the risks from water damage and mould. The papers go into detail showing how cardiac problems as well as symptoms like multiple chemical sensitivity are very strongly associated with exposure to these toxic environments. I hope you can use these easily obtainable papers to help you convince others that mould & water damage MUST be taken seriously and not dismissed. The data shows there is a causality between exposure to dampness microorganisms (DM) and the prevalence of multiple chemical sensitivity. The authors conclude that adverse symptoms after exposure to DM can occur together with a range of other neurological symptoms and fatigue and is not a medically unexplained syndrome or a functional disorder. Next time, someone tells you it's all in your head about your mould concerns, please cite this video and the research it's based on. REFERENCES: Hyvönen S, Lohi J, Tuuminen T.

Sentinel Environmental Screening for the Coronavirus

23:042 years Ago
New research from the US military shows that the SARS-CoV-2 virus can remain stable on the skin for 14-days. The higher the temperature, the lower the recovery. Therefore, the colder the environment, the longer the coronavirus persists on surfaces like skin, banknotes and even clothing. In this weeks Livestream I’m covering the role of ‘Sentinel monitoring’. This aims to test out selected high touch surfaces in an effort to detect the presymptomatic (before they show symptoms) and the asymptomatic (people who never show symptoms). New breaking research shows that swabbing the environment can detect those environments that are 10-times more likely to show a positive coronavirus case during clinical testing. The conclusion from the research is that environmental screening can help identify workplaces that are likely to hide spreaders! Surface testing in the environment should be used alongside clinical testing of people. Of course, reach out to us if you need surface swab testing at your workplace. Fast and efficient onsite service.

Post Cleaning Assessment for the SARS-CoV-2 Virus on Surfaces in the Workplace

1:532 years Ago
Why would you want to test your surfaces after cleaning? Well, frequently touched surfaces can hide the SARS-CoV- virus. If you have a busy workplace or you need to clear a site after one of your staff or clients tests positive for the virus, then we can help you. Use the results to validate workplace cleanliness and if there is a positive test, you can use this information to deep clean or optimize your procedures. Call or email to discuss your testing needs. #covidau #covid19australia #COVID19Aus

Environmental Monitoring of Surfaces for a COVID-Safe Workplace

32:342 years Ago
As Australia re-opens, some States like Victoria are experiencing a resurgence in case numbers. Was it the protests, is it the returning travellers, is it the asymptomatic spread, is it the super-spreaders? All valid questions, without clear answers...but what's your business to do IF you WANT and NEED to re-open but you want to do this SAFELY? In today's livestream I want to speak about the important role of surface contamination. We all know that hand sanitiser and regular hand washing is globally promoted as a mandatory step - but have you stopped to think about all the reasons why? Obviously touching other people with a handshake is easily understood as a risky behaviour - but what about all the other things you touch without thinking much about it. Your phone, the steering wheel, the hand rail on that chair, the ATM machine, the shopping trolley and on and on. It's these high-touch surfaces that can act as reservoirs for the coronavirus. Those people actually infected with the virus also shed it into their local environment and it's spread on air currents and on particles of air pollution. These land on surfaces and can act as fomites for further hand to person contact transmission. In this way the virus can be spread. Now, there's lots of research that discusses the replication competence on different surfaces and how rough or smooth an object is all has a role to play. But, juts assume that the coronavirus can remain replication competent for up to 7 days on surfaces depending on where they are and what they're made from. In today's livestream, we go into a shopping centre in Melbourne and demonstrate how we can test commonly used (and touched) surfaces to look for the SARS-CoV-2 virus. We're looking for the RNA using qPCR molecular screening. In the video we show you live what we found!!! It's amazing (and shocking): 1 in 5 of the tested surfaces FAILED. That's like 20%. The literature predicted a FAIL rate of juts under 17%. If the limited range of surfaces we tested FAILED - imagine what your building is hiding? I also review the Key Results for a Survey of the Australian public that showed how they feel about the issue of surface contamination and PCR swab testing. The results show that unequivocally, the Australian Public want surface testing in the workplace. We are offering qPCR swab testing to businesses across Victoria. We come to you, suit up into PPE and will test your building. If you PASS - great news. If there are any FAILS, then you can take appropriate action. The AIM of swab testing is to provide evidence that your cleaning protocols are actually disinfecting the areas as anticipated. Cleaning g validation in this way over time builds up a picture of how effectively the business or facility is maintaining hygiene standards regarding the coronavirus. The entire point of qPCR testing is to inspire confidence during the re-opening. Where to obtain an onsite coronavirus surface swab test: JONES, C.L.

Environmental Surface Testing for SARS-CoV-2 at a Shopping Centre

9:102 years Ago
Demonstration of how we're using qPCR to test for SARS-CoV-2 at a local shopping centre in Melbourne on Wednesday 24th June 2020. This method is different to testing people - but similar, in that we're testing surfaces for virus that has been shed into the environment. People can become sick with COVID-19 due to contact with the virus. This is called fomite transmission. My lab, Biological Health Services can test your surfaces and help you validate your cleaning success. The aim of testing for the SARS-CoV-2 virus is to help validate that your policies and procedures for cleaning are effective. This is a very important component of creating a COVID-safe workplace. Reach out to us on the telephone, on social media or via telephone to arrange testing at your building or public space, transport, infrastructure or for general public health awareness and monitoring.

Asthma and the Older Cohort + Does Sunlight Influence Nosocomial Infections?

28:512 years Ago
Have you ever wondered if some factors make asthma worse in older adults? Find out what are the Top 7 reasons why asthma can be made worse indoors. Once you know what they are, you can do something about limiting risk. I also want to look at the relationship between the environment - and in particular temperature - and how this is linked to rates of hospital acquired bloodborne infections. The results for bacteria and fungi will no doubt surprise you. Also it's our 52nd show, so we've been doing these weekly LiveStreams for 1year. Check out all the back episodes on YouTube @drcameronjones or listen to the podcasts on iTunes or your favourite streaming service or go to TOP 7 Things Older People Should Be On The Lookout For To Reduce Their Levels Of Allergen Exposure: 1. Poor bathroom ventilation 2. No HEPA vacuum 3. Furry/feathered pets inside 4. Mould/moisture present 5. Dust 6. Pest/rodents 7. Cigarettes Contrary to expectations: it was NOT warm and humid weather that had an impact on bloodstream infections it was warm and relatively dry weather which was associated.

What to do if you find mould in your new home during construction?

16:012 years Ago
It could happen if there's been a lot of rain, a delay in the building process, or if timber has sat out in the elements for too long before being covered? Mould, mould and more mould...what do you do if you find this? Well - this episode will cover this important topic. Firstly: might not be as bad as you think! Discuss the matter with your builder. Discuss your health and safety concerns. Discuss your asset value concerns and implications that mould might have for building integrity. This episode will cover what we recommend. Document, document, document is really our best advice. When in doubt: test, test, test. Remember the principal way to deal with mould is: SOURCE REMOVAL.

5 Fungal threats you might have missed due to COVID-19

27:463 years Ago
With all the attention at the moment focussing on the SARS-CoV-2 virus, the rest of microbiology has taken somewhat of a backseat. While the COVID pandemic has restricted behaviour and led to 6.4M cases and 383,000 deaths, the number of illnesses and deaths caused by fungi is also of epic proportions at 800M and 1.6M deaths annually. With global warming a serious problem for humanity, I want this week to discuss some of the reasons that fungi are often neglected. I want to shed some light on why this is, and what we should be discussing. We'll look at forced evolution in the lab and why Temperature optima may well turn out to be the best predictor of the next fungal plague or infection illness. Will it turn on us or our agriculture crops? Thats the crux of food security - and mycotoxins and other direct infections do more than reduce our access to bananas! I'll also make a short review of some of the fungal catastrophes to put this into context as well as discuss what we know about COVID and co-infections from Aspergillus fumigatus. Topics: 1. Fungi are under-appreciated as a source of infection and co-infection. Viruses are now easily understood to be a source of infection between people and most people understand the concept of hospital acquired bacterial infections, but… 2. Fungi have significant genetic flexibility and rapid evolution 3. Global warming and fungal disease, invasive fungal infections after natural disasters 4. Plant and agricultural fungal threats much better understood - food security impacts potentially devastating 5. Short history of catastrophic events caused by fungi REFERENCES: Casadevall A.

How to validate cleaning using your phone for a COVID safe workplace

13:373 years Ago
Let me show you how you can quickly and inexpensively turn your mobile phone into as device that can 'see' in ultraviolet. Being able to see in UV is useful if you want to double check that your cleaners have done a good job. Did you know that you can use a fluorescent highlighter to mark high touch items and then check with UV to see that it's been cleaned. This is very useful and important especially as economies around the world tentatively re-open. Effective disinfectant cleaning must begin with care and attention to areas or items in the built environment that have a high probability of having shed coronavirus on them. All you need is some sticky tape, a blue and a purple Sharpie and a fluorescent marker. Once you've made your 'UV lens' for the flash on your phone, go around your workplace and mark out some items you want to validate that your cleaners have cleaned. Under UV light, these will fluoresce, but if cleaning has been successful, then the dye in the highlighter will have been removed and you can have greater confidence in the knowledge that the cleaners have done their job as expected. Of course, if the items or areas fluoresce, then you can make some adjustments to your cleaning requirements and monitor further.

The COVID safe workplace and how to validate cleaning at your business

18:573 years Ago
Australian businesses are soon to begin reopening. The threat from SARS-CoV-2 is not behind us even with lowered numbers of cases across the country. We still need to careful - and the role of deep disinfection cleaning is more important than ever. This week, I want to discuss how UV light can be used to validate cleaning efficiency. If you’ve ever wanted to check up on your cleaners - and make sure they’re doing a good job - this show will show you how! This is called environmental surveillance and is a common method for validating cleaning efficiency. #covidsafe #covidsafeworkplace #cleaning

COVID Toes, loss of smell and preview of our survey results on COVID-safe workplaces

21:493 years Ago
The way humans behave is central to the ways in which SARS-CoV-2 can be transmitted. Whether it’s a cough or a sneeze or touching something that’s then handled by someone else, we need to change behaviour (and quickly) to minimise transmission in the absence of pharmaceutical interventions. In Australia, as coronavirus restrictions are relaxed and businesses are being encouraged to prepare for reopening, the risks once again loom for fresh wave/s of infection. So, what does COVID-safe awareness look like? Overarchingly, it’s using scientifically and medically valid information to make choices that minimize harm and in the first place, accessing this information and using it for self-education and then applying it for your own and others benefit. This week, I want to focus some attention on 2 interesting papers. Both of them are about non-fever warning signs that the exposed and then infected individual may go on to develop into COVID-19. Think of today’s livestream as a symptom-checker that relies on 2 recently published papers that I’ll summarise briefly. The first, looks at how the loss of smell is correlated with a positive diagnosis of COVID-19. The second paper reviews an interesting case of discoloured lesions affecting the feet that pre-date fever symptoms and have become known as “COVID Toes”. Whilst there is still much to learn about the transmission and diverse epidemiology seen with this coronavirus, the literature offers us these 2 easy-to-remember considerations that might be useful. The actual papers stress that the case studies are in the main seen in young people. With the race to re-open Schools, it might be prudent to be on the lookout for funny feet or a non-smelly fragrance! The last part of this livestream will briefly summarise 2 key points from a recent survey into the knowledge and perceptions of direct contact transmission pathways in Australia. We administered this survey to a cohort of Australians, and I’ll give you a very sneak peek since the paper is now at the peer-review stage. I’ll cover the full results in the next few weeks especially as this relates directly to the creation and maintenance of COVID-safe workplaces for both staff and consumers REFERENCES: Predictive value of sudden olfactory loss in the diagnosis of COVID-19 Antje Haehner, Julia Draf, Sarah Draeger, Katja de With, Thomas Hummel medRxiv 2020.04.27.20081356; doi: Posted May 03, 2020.

Preparing for a COVID-safe workplace and environmental surface testing for SARS-CoV-2

30:253 years Ago
Social easing restrictions will eventually happen - but what does the research say? In today’s episode we’ll be reviewing what the literature says about direct and non-contact forms of virus transmission. I’ve just published a review paper on “Environmental Surface Contamination” and I’ll be picking out the key 🔑 points. In the media today, there’s some potential good news regarding how businesses should prepare for reopening. But what should they be considering? The Employment Minister, @senatormichaeliacash suggests that retailers create “COVID-safe workplaces”. With this in mind, I’ll be setting out some valuable information about surface contamination and what areas and items should be carefully monitored and screened. Apart from simply cleaning more carefully, some workplaces should be considering updates to their cleaning audits and how they may need to test surfaces to confirm that cleaning has minimised and virus that could have been shed. The utility of PCR swab tests will also be discussed as a pro-active way to perform cleaning validation as a form of environmental surveillance REWFERENCES: JONES, C.L. (2020).

Pollution increases the risk for mould allergy and COVID-19 infections

36:283 years Ago
Have you ever wondered how the air we breathe can cause respiratory irritation? What is in that haze or smog that sometimes blankets urban cities? Sure, it probably contains chemicals and maybe even smoke - but there's a lot more to it than just a chemical soup. In today's Livestream we're going to deep dive into particulate matter, or PM and review what's known about the fungal contribution. Then we're going to look at the inflammatory potential of mould fragments in the PM2.5 and PM10 and ultra small size ranges (yes, even down to the nanoscale). Then we'll look at how cytokines are involved. From this perspective, we'll then look into the connection between particulate matter and the spread of SARS-CoV-2 and COVID-19 infection levels. There's some excellent emerging research saying that the worse the PM, the higher the number of cases of COVID-19. Watch the livestream to see if it's just the presence of PM that causes for example an immune reaction, perhaps pre-disposing people to SARS-CoV-2 or if the particles themselves are transmitting the virus.

Reading that documents suggests that levels less then 500 mean the building is not water damaged - especially if you live in Finland. But what about the rest of the world? Today's livestream delves into the topic of colony forming units - which are the numbers of discrete fungal colonies that appear in petri plates when exposed to the air. The numbers on the plate can be translated into units per cubic metre of air. When this is done, we have THRESHOLDS. Think of these as numerical traffic lights. At green, it's OK indoors, and your mould levels can be considered normal...but what happens if the petri plate traffic lights show AMBER or RED? Some great French research uses 3 ways of measuring risk indoors using the CFU and links this with the experience of asthma and rhinitis. Towards the end of this livestream I alos compare the French thresholds with the Australian Mould Guideline (2010) by Dr Heike Neumeister and we see a strong correlation between the French and the Australians. This is great news for anyone trying the make a link between indoor mould exposure and adverse or the potential for adverse human health. As part of the breaking news segment, I cover some new research showing that some occupations make it more probable that you may come into contact with SARS-CoV-2. Watch until the end to find out the 5 classes of at risk occupations. REFERENCES: Reboux G, Rocchi S, Laboissière A et al.

Coronavirus in cats – Evidence of infected cat populations in Wuhan

18:083 years Ago
This is the 2nd paper out in less than a week that discusses how pet cats are becoming infected with SARS-CoV-2. This paper provides evidence that cats are becoming infected with coronavirus from contact with infected humans (their owners). The paper raises some disturbing implications for cat quarantine to minimize transmission.

Can my pet get COVID-19?

25:233 years Ago
This week we're taking a mould holiday and instead focussing on a very serious contemporary health crisis. Today, I want to review what we know about SARS-COv-2 and virus transmission in pets. There has been some disturbing new stories about this virus in 2 dogs and then 2 cats. Investigations in Hong Kong revealed that the virus could be detected in at least one dog. The CDC cautions that there is no immediate risk to people from their pets. Obviously, no one wants people to start fearing their pets, but these early reports certainly suggests that there is some form of transmission even if this is juts settled RNA virus onto the pets fur. However a bombshell of a paper came out overnight showing that SARS-CoV-2 is spread via droplets in ferrets and cats. This is alarming and suggests that perhaps more widespread epidemiological testing needs to be undertaken in at least cats. The last part of this livestream focuses on masks and if they offer scientifically valid reasons for wearing them. Review a paper that shows that mask wearing on public transport prevents transmission to others. The final paper looks at 3 types of masks and notes that mask wearing in combination with use of hand sanitiser can help minimise transmission. REFERENCES: Chen H.

Fungal Growth in Carpets

33:493 years Ago
On this week's livestream I'm going to cover the topic of microbial contamination in carpet. In Australia, with over 17% of insurance claims being water-related, the probability of your carpet being water-damaged and mould-affected is high. Now, consider the context that asthma costs the community billions of dollars every year and that approx. 35% of asthma cases are caused by mould and dampness (tune in for these references!). You should be aware that there are 3 main types of carpets: nylon, wool and polypropylene. Which one is better or worse for your respiratory health? What does dust do to the ability of your carpet to induce asthma? What does the amount of humidity do? These are some of the key questions we're going to answer in today's livestream. Once you know which carpet, which humidity and what other factors impact on your carpet cleanliness, I'm then going to discuss which cleaning methods are best for removing these microbial contaminants. As part of the weekly 'Breaking News' segment, there a fascinating new paper that's come out that explains how mould damages the lung. This paper provides fundamental evidence in support of the reasons that even low levels of mould can cause harm top people. We're also going to review 2 papers that have come out about the COVID-19 pandemic. The first is a review of what we know of the medical journey for some of the first virus infected patients in China. This information showed that severe pulmonary disease is the #1 reason for admission to the intensive care unit (ICU). Viral infections (and before COVID-19) became the central worry on all our minds, the risk from severe influenza pneumonia resulting in acute respiratory distress syndrome (ARDS) may in fact be made worse by Aspergillus infections. The relationship of co-infections with other pathogens like bacteria and fungi cannot be underestimated with COVID-19. REFERENCES: Dannemiller K, Weschler C, Peccia J.

Microbiological Literacy & COVID-19 Awareness

37:113 years Ago
Now that the WHO has informed us all that the virus is now a Pandemic. This week’s show will suspend our discussion on mould issues to bring you some important information on the COVID-19 virus. This week we’ll be covering microbiological literacy, fractal scaling behaviour in death rate and how this is linked to what we know about the trail off of infection rate, the role of humidity and general virus transmission and infectivity as well as debunking some myths surrounding some claims that the COVID-19 is a laboratory made virus. I also interview Richard Anthony from Eze Training who’s is launching a new course on infection control especially updated to cover COVID-19 that is aimed at the general public, hospitality staff as well as his core train demographic from the tattoo and allied body and beauty arts field.

How To Use Saunas For Mould Detoxification – Part 3

44:203 years Ago
In part 3 of this video series I'm covering how sauna bathing has been used to treat Alzheimer's and Parkinson's disease. I review what the Global Sauna Survey has to say about which medical health problems respond best to sauna heat. We also delve into the intriguing benefit of Niacin or Vitamin B3 and how this has been used in the treatment of Gulf War Illness + sauna, but may also be of benefit for those with Multiple Sclerosis. The serious problem of chronic fatigue is well-linked to both cardiovascular dysregulation and environmental triggers like mould - so I draw your attention to several key papers that have used sauna heat + rest (called Waon therapy) to treat these patients. The outcome of brain imaging has shown that the sauna improves cerebral blood flow, leading to positive outcomes for those with chronic fatigue.

Find out how sauna and exercise and nutritional supplements have been used to help people who suffer from an environmental illness termed Gulf War Illness. This builds on what we know about the potential benefits of sauna for both firefighters and people who are dealing with symptoms attributed to mould illness and having spent time in water damaged environments. Also, we'll cover how sauna might work? Does it operate my reducing inflammation or by affecting oxidative stress? We'll also place sauna bathing into the 4-element model of mental health. Finally, we'll talk about some basics of the use of niacin in combination with sauna. Next week, I'll be covering what the literature says about how sauna can help in neurodegerative disorders like Parkinson's and Alzheimer's and I want to touch on what the literature says about Multiple Sclerosis.

How To Use Saunas For Detoxification From Mould

21:303 years Ago
In today's live stream we are going to be focusing on one of the most important aspects of mould exposure. This has to do with how you can potentially take control of your health. We’re taking a close look at one of the methods that has been written up reasonably extensively in the peer-reviewed literature that talks about practical methods that have shown strong effectiveness in people who have serious mould symptoms. In part 1 of this live stream I'm going to be reviewing some of the key papers that discuss how saunas have been used for mould detoxification. I'll also be discussing how saunas have been used by firefighters in an effort to combat problems associated with chemical and particulate matter challenge that they are exposed to as part of their work. Therefore, in part 1 I will review both recent and existing literature on which you can make some decisions regarding whether you want to incorporate this health modality into your own detoxification strategy. In part 2 we will discuss some of the fundamentals of infrared thermal energy and in part 3 we will talk to practitioners and people who use saunas for this purpose. In this livestream we will also review some of the current breaking news in the microbiology literature that has appeared in the first week of February.

Can A Questionnaire About Mould Help Explain Some Of The Risks?

35:333 years Ago
Trend detection and identification has important ramifications in public health. With regard to water damage and mould, often the occupants own version of events and 'lived experience' inside the home is lost in the quicksand of data from spore traps, tape lifts, moisture levels and ERMI readings. We ALL want to know if there is an underlying trend based on the observation of random variables over time? BUT, what are those random variables? This Livestream focuses on this problem by exploring 2 different self-reporting questionnaires. Interesting questions about the ability for surveys to capture trend direction and discover persistent or anti-persistent (unstable) conditions warranting further fine-grained assessments and inspections are detailed.

Oil of Cloves Expert Interview

47:033 years Ago
In this week’s LiveStream on Thursday 12th December at 11am, I’m covering the facts everyone should know about oil of cloves. What’s it used for, how to use it (as a liquid or vapour), what to expect and where to get it. Joining me for an interview is 9:53 Rachel Shaw from The Oil of Cloves Company. She’s going to be telling us all how to best use this essential oil to control mould in the home or office. Essential oils have shown remarkable antioxidant and anti-bacterial and anti-fungal activities when used at low dose ranges from 0.01 to 10 mg/mL in animal and human cell models. This is mainly due to the diversity seen in the range of phenolic components in the essential oils. Get the inside view on how oil of cloves has been used for mould control and what other oils are available that can help you.

Microbes & Asthma Development In Children

32:073 years Ago
Asthma, thunderstorms, hot weather, rain, and wind...what's happening to the aeroallergens? Is asthma getting worse? What factors affect children? This week we take a look at this important topic and discuss some of the fungi to watch out for to minimize asthma reactions for you and the young ones in your family. I’ll also be discussing how oxidative stress early in live may lead to longevity benefits and we look at the role of Vitamin D and its anti fungal properties.

Breathing in mould spores causes anxiety, memory deficits and increases pain perception

28:203 years Ago
Sickness behaviour following mould exposure has finally been validated. It turns out that anxiety, memory deficits and pain thresholds are all switched on by BOTH toxic and non-toxic mould. The research shows that mould spores and mould cell wall fragments can adversely affect the brain and influence behaviour by challenging and activating the innate immune system. In this week's Livestream I'm going to be talking about these important findings and making them understandable for a lay audience.

Professional Carpet Cleaning Secrets

53:263 years Ago
What does professional carpet cleaning mean? How does professional carpet cleaning work? Will it work for mould removal after water damage? What about my car? "Help - I spilled red wine on my carpet! What should I do now?" To answer these questions, I interviewed Joseph Lotesto from (Easy Clean Steam-Cleaning). He's an expert at professional carpet cleaning and will be sharing his knowledge, advice and experience. We'll be covering end of lease cleaning, removing pet and urine smells, and touching on the future of surface textile cleaning. We'll also be covering how often to clean your carpets and what tips Joseph can pass on about reducing allergies from the particles and microorganisms that can become trapped in the fibres of your carpet or upholstery. As well, I'll be covering some of the scientific research behind the efficiency of vacuuming and a comparison between different carpet cleaning methods for the removal of microorganisms from experimentally contaminated carpets. The spotlight on this research alone is worth joining the livestream since how do you know which environmental cleaning method is best for such tasks? For example, do you know which carpet cleaning method is best for cat allergen removal? Finally I'll round out with a summary of the Top 5 cleaning secrets from Joseph with a discussion of the energy requirements for cleaning different types of flooring. The results and tips might surprise you as well as being useful for maintaining public health inside your home or office !

Does Bleach Kill Mould?

31:473 years Ago
This week we’re talking about disinfectants and more specifically bleach or sodium hypochlorite. “Does it work, no it doesn’t, look it just feeds the mould, no it doesn’t, yes it does, it makes the mycotoxins worse and simply changes mould from one colour to no colour” Fact or fiction? We all know, there's a lot of websites that say conflicting things. Who do you believe? You might even know the answer, maybe you’ve already made up your mind? But wait - what does the science say? To bring some perspective to the bleach debate, I’m going to take a look at what the National Wrestling Coach Association has to say. Up to 20% of wrestling injuries are caused by skin infections. Tune in to this episode and find out what the martial artists discovered about bacterial transmission and how this leads to improved disinfection methods and best practice for surface decontamination? HINT: contact sports are associated with an increased risk of skin infections, but the conclusions from their research are valuable (and transferrable) to the indoor living environment and similarly, to water-damaged interiors. Join me tomorrow as I go through this very practical topic since all of us from time to time need to clean up the mould. After all, over 70% of homes test positive for mould and research shows that windowsills are often the most frequently contaminated sites. What are we to do? Reach for the latest kill mould solution from the supermarket or hardware store, reach for the latest ultra-green plant-based carbon credit contributing liquid or test out something simple like vinegar? Which disinfectants are best for porous and non-porous materials? What about essential oils? TEASER ALERT: Clove oil (a hidden secret)...see the graph showing its antibacterial effect. All these are viable options you might consider when you need to clean the mould away. But, before you begin, I want to shine a spotlight on what the research says so you can make better-informed decisions for your next cleaning task. Stay till the end and I’ll also show you a simple bathroom hack for cleaning grout joints that have gone mouldy? REFERENCES: Rogawansamy, S., Gaskin, S., Taylor, M. And Pisaniello, D. (2015).

How To Best Clean Mould Out Of Your Wall Mounted Split System

37:223 years Ago
Sick building syndrome is a broad way to describe the range of potential health issues that are associated with bad indoor air quality. With summer on the way, I want you to think about that wall-mounted inverter. Also called an air handling unit in the literature, they sit silently on the wall, heating and cooling at the press of a button…but have you looked inside lately? There’s more than just a gauze air filter at the top, what about the condition of the coiling coil fins, ductwork, blower wheel fan blades, insulation, and drain pans? Several years ago, I did an inspection of a property where one of the occupants was incredibly sick from mould exposure. You might have seen her story and seen the disturbing pictures of her skin? I’ll be discussing that by way of context. In any case, I thought I would interview an expert to bring you the latest industry best practices on this insidious problem. I’ll be talking with Brian from Organic air con cleaning Gold Coast (Organic Air Con Cleaning) and he’s going to be sharing some advice and recommendations and give you the low down on everything to do with cleaning your air conditioner. Learn how he can help you achieve a mould-free split system. Listen to him discuss some of the people he has helped and what you must consider to optimize your indoor living environment if you rent or own a home with split systems.

Public Housing Mould Nightmare

0:423 years Ago
With housing affordability getting worse and worse there are some 800,000 people who are accessing Public and Community Housing. Often these people who are renting from the Government or from service providers into this subsidised sector are on low incomes - many have personal crisis situations or have a disability or are indigenous. On this weeks’ show we’re interviewing a long term resident of Victorian Public Housing. She explains in her own words what’s happened to her health. We did a mould inspection for her some 4+ years ago that resulted in Housing Victoria stepping in to quickly remove this Family. Unfortunately at her new dwelling she and her daughter have continued to be affected by leaks and building defects. I wanted to bring you her story so maybe the Department can step in again and do something for this Family. The second reason I think this story is important is that many people in public housing need advocacy on what is often a hidden problem. If you know or suspect someone who might be vulnerable and is knowingly or unknowingly being potentially exposed to mould and water damage, please speak up and start talking about it and agitating for change. #mould #publichousing #waterdamage Enjoy & 👇Comment Your Thoughts Below👇 ★ Follow & Like On Facebook: 👉 ★ Follow BIOLOGICAL HEALTH SERVICES On Instagram: 👉 ★ Website for BIOLOGICAL HEALTH SERVICES: 👉 ★ Website for DR CAMERON JONES: 👉 ★ Subscribe On YouTube: 👉 👉 ★ Follow DR CAMERON JONES On Twitter: 👉 ★ Follow DR CAMERON JONES On Instagram: 👉 ★ Live Streaming Calendar: 👉

What You Need To Know About Mould Evidence & The Rule in Browne v Dunn?

18:523 years Ago
Are you considering taking legal action against a party concerning your water damage and or mould situation? Will you need to engage one or more independent experts to provide evidence for you? At the pointy end of this type of dispute, the expert/s may have to provide and defend their own evidence. This livestream covers one aspect of this important topic. The: what, why, who and how will this evidence be looked at and dissected? The context for this livestream was my own requirement to be an expert witness this week in a building related mould case. As part of me meeting the barrister in the lead up to the hearing, I stopped for coffee before the meeting. As I was paying, I picked up a newsletter from the counter of the ground floor coffee shop of his Chambers. This was written by a solicitor, Dr Jason Harkness and was on the exact topic I needed to read about! I have borrowed very heavily from what he wrote and have quoted him word-for-word for the most part. The reason for this is that I think it's important to highlight some of the context of how evidence will be used in these sort of disputes - especially since I have just been through this process as the expert. Please note, I'm not a lawyer. So take this live stream as a window into the 'legal mind' and seek your own legal advice for your own situation, this live stream is for educational and entertainment value only. However, in the spirit of how information and meaning is conveyed, I wanted to highlight some of the Key Points that Dr Harkness has made with respect to evidence and courtroom practice. The reason I think this is important is because the pursuit of truth is one of the key aims of the scientific method. Because so many contemporary mould cases rely on expert opinion, much of which is scientific, then these principles and others become very relevant. REFERENCES: 1.

Bathroom Mould & Ventilation

45:533 years Ago
In this week’s live stream I’m having a guest on the show - who’s going to be talking about his experiences building a brand new home and the problems he’s had and discuss some of the pathways towards a resolution. This is a real example of some of the practical problems that others may also be dealing with across Australia. This interview shines a spotlight on building defects and how they are handled, as well as the impacts on family health and safety. It’s within this context that I’m also going to be addressing the issue of exhaust fans and ventilation especially in bathrooms but also in other habitable rooms. There's a well defined Building Code of Australia that covers ventilation requirements for toilets, bathrooms and kitchens. But what about when you discover your vent simply goes into the roof void or you're experiencing a build-up of condensation on your internal window glass, despite making sure you are in fact 'ventilating your home'? What's going wrong? Also, when is it permitted to vent into the roof void and when should you consider this bad practice and why? We’ll also be discussing some of the options for improving ventilation and reviewing what the research literature says about exhaust fans and their relationship to the airflow map across and through the home layout and how this impacts on things like condensation and odour dissipation. Finally, there will be a short discussion on what the research says about asthma and exhaust fans.

Can Mould Cause Depression?

39:443 years Ago
Are you happy? If you aren't aren't, let me ask you a question? Has your home or office been water damaged or show signs of visible mould? I received an email the other day from a client with bad news informing me that his wife has breast cancer. He told me that she had suffered from depression ever since reluctantly moving into a property that had a severe water damage problem and that had been concealed by the real estate agent. This got me thinking about all the research talking about mould exposure and mood disorders like anxiety and depression and even IQ. In this week’s Livestream, I’m going to review 6 key areas where mental health problems can occur due to mould and water damage: 1. Families that know about mould and water damage 2. Disaster recovery workers 3. The elderly 4. Children and pre-adolescents 5. The immune system. What’s going on inside your body? 6. Tenancy Is depression the hidden epidemic often not spoken about when discussing building-specific factors surrounding mould and adverse indoor air quality from aeroallergens and other microbes?

Chaetomium Mould: Health Effects & Exposure Levels

29:443 years Ago
Join me as I present a livestream overview of a well-known mould called Chaetomium. I'll be covering the health effects and exposure levels, and to begin, I’ll show you what it looks like under the microscope, and in the lab on petri plates, and then I want to present a case study from my files, showing a vigorous Chaetomium mould-contamination within a wall cavity of a water-damaged building. This fungus loves cellulose and degrades it even at high temperatures, producing mycotoxins, and well over 500 different bioactive metabolites, some of which show considerable promise in medicine.We'll be talking about its role as a hidden allergen and how it can cause asthma and rhinitis, and as a causative agent in human infections, and in the immunocompromised, as well as its pervasive role in Sick Building Syndrome (SBS). I'll be talking about how Chaetomium preferentially affects cellulose based materials like particle board, cement and stone as well as gypsum board, especially those reinforced with composite binders, and even wallpaper. I'll be reviewing typical building materials that are most prone to attack and also those building materials where even after inoculation with Chaetomium, the substrates appear resistant to visible mould growth.I'll then be rounding out this livestream by talking about a few methods to remediate Chaetomium and contaminated building materials, and also reference how ultraviolet germicidal irradiation has been used to protect packing and storing materials in museum collections.I'm then going to finish by discussing acceptable levels of Chaetomium exposure. Finally, I want to highlight that it’s not all bad! Chaetomium toxins and the polysaccharide metabolites that strains from this Genus produce are potentially highly useful for us - and indeed, are finding increasing application in medical research for their antibacterial and anti-cancer properties. Think lung cancer and ovarian cancer. Thanks for watching and for joining me in diving into the biology of this fungus in detail. Post your questions below in the comments. REFERENCES:1.

The Home Environment & Better Health

21:563 years Ago
Today in this live stream I'm talking about the home environment, and better health, and I'm really excited about this episode because I'm going to be discussing three topics which are a real passion of mine, and these are: healthy buildings, indoor climate and energy efficiency, and we're going to be talking about how the home environment can impact on your health and mine. To begin, I'm going to be reviewing The Indoor Generation Report which is something that came out by a really interesting company in 2018 by the name of I'm going to be showing you a video that created which highlights, many of the factors about indoor living and in many cases, the invisible pollutants that build up inside homes, and how things like damp and mould can be contributing to increasing asthma risk by up to 40%. Importantly, I'm going to be asking the question: can risk factors be identified? I'm going to be defining what sick building syndrome is, I'm going to be talking about the typical symptoms that affect the eye, nose, throat and skin as well as issues of fatigue and headache which are commonly correlated with sick building syndrome. With this context, I’m then going to review a fascinating paper that came out in 2019, which is Chinese research that examined over 36,000 people across six cities. And why this is important is that they used a questionnaire to evaluate the health status of children and what the home environment was like. So, things like, whether windows were opened in spring, summer, autumn and winter, whether or not they kept a cat or dog. Whether they own the home or rented it, the construction year, whether they live near major highways. All of this and more were and are some of the questions which they used to evaluate the home environment. And it’s my opinion that hese same questions can be extrapolated from the Chinese research to Australia. I'm also going to be highlighting something called the dampness and mould index, which these lead authors developed, and it is a quantitative scale, which ranges from zero to six on a numerical scale. And so, some of the factors that they look for when doing the questionnaire within these Chinese families, was: the presence of damp stains, mould spots, actual water damage and mould odor. And so they ranked these, and were able to use this in their research as an index of exposure. Interestingly, some of the conclusions that they discovered are somewhat obvious for example: old buildings had more dampness and mould. But, relative humidity was not associated with indoor dampness and mould. Again, another obvious one, rain was associated with water damage and damp spots and increasing temperatures are associated with more self-reported water damage. Other interesting points from their research, showed that people who are in managerial and professional jobs report more water damage in their homes compared to those people who do manual or blue-collar work. Now, some of the key results from the Chinese research was that: redecoration is associated with rhinitis, skin, headache, and fatigue. And similarly, the presence of new furniture is associated with throat, skin and fatigue symptoms. And there are a lot of other results that I'm going to be going through in this live stream so these are just a few of them. I also want to focus on the question: is dampness a respiratory weapon? And what I mean by that is that German research reveals that 84 million Europeans live in homes that are too damp, and this is linked with respiratory illnesses such as asthma and COPD. And so, another key question from some recent European Research that also came out in 2019 looked at this question: Is dampness mould and mould odour associated with the onset and remission of respiratory symptoms like asthma and rhinitis in adults? And the really important thing about this research is that they are looking at long term health problems, not just what are termed ‘incident’ symptoms. For example, like the thunderstorm asthma event that occurred in Melbourne, which was an episodic or an incident event. And so, this issue of whether or not dampness is a respiratory weapon silently lurking in some homes, really cuts to the core of the question: does long term dampness in a home lead the occupants to an increasing likelihood of adverse health? And the answer appears from the European Research that this is definitely true. So I'm going to be going over again their questionnaire because these are the same types of questions that you should use when you're trying to explain to someone about your own experience of living in a water damaged or mould affected building, because these variables such as water damage, dampness ,visible mould and odour can all be used to explain to a stakeholder like a property manager or a landlord or a builder, or your insurer that your home environment definitely appears to be presenting with a problem.

What Is Post Remediation Verification?

19:293 years Ago
This video focusses on the assessment remediation and post-remediation verification of mould in buildings. This is a really important topic of risk management, and anyone who has had an unexpected water damage event at their property may be familiar with the process of post remediation verification, or PRV as it's often abbreviated especially when mould contamination has developed. I'm going to review the ANSI IICRC S500-2015, Section 13.4.4 as well as the ANSI IICRC S520, Section 15 because the former deals with ‘water damage restoration’ while the latter deals with ‘mould remediation’. These are nested Standards because water damage and mould tend to follow one another, but the way in which post remediation verification is defined and described is slightly different in each Standard. I also discuss the unreleased ASTM WK52711 - New Guide for Post-Remediation Verification (PRV) Following a Fungal Remediation Project. I also review some of the other literatures that exist with regard to post remediation verification. And the reason I'm highlighting this is that it's really important to validate the success of your mould remediation project - especially if this is part of an insurance claim or any dispute between various stake holders. I cover the 'How, What and Why' of PRV. What SHOULD you be looking for? What should the post remediation verification report include? This is especially important if you’re trying to make sense of works that may have occurred at your property or are concerned for your health or need to know if a public health issue exists from residual contamination? I highlight some of the information that should appear in your PRV. This includes at a macro/micro level: visual inspections, moisture mapping, cleaning assessment and data for air and surface samples. I’ll also be talking about the difference between qualitative and quantitative evidence. Why is this important? At the end of the day, you need documentation that validates the remediation or restoration (cleaning) process. I also stress that post remediation testing may need to check for mould and bacteria and also yeasts. REFERENCES: Maunsell, K.

Unboxing a DIY Mould Test Kit

33:543 years Ago
On the 167th year since Julius Richard Petri invented the petri plate, in today’s livestream find out what they can do for your indoor air quality or mould contamination concerns. If you’ve ever had unexpected water ingress and are suspicious about mould you have probably looked up on Google and discovered there are DIY Mould Test Kits. But where did Petri plates comes from? Let me quickly review the beginnings of microbiology. The Petri plate was invented by Julius Richard Petri 167 years ago. He worked for another famous microbiologist called Robert Koch who was a bacteriologist who discovered that a microbe called anthrax caused disease. Before petri plates, Robert Koch cultured his microbes on slices of potato. Julius Petri used a shallow glass dish instead of potato slices and the Petri plate was born. Why Mould Test Kits: 1. Convenience 2. Price sensitive 3. Suitable for residential tenancy, homeowners, offices, shops, cars 4. Quantitative results in colonies per cubic metre of air for air tests. 5. Qualitative results for swab tests showing number of discrete colonies per plate. 6. Reports shows the data as well as the growth time series. This shows you in a visual way that anyone can understand what’s going on. If it grows on the plate…it could be growing like this in your home or office. ‘Makes the invisible visible’. How Accurate are Mould Test Kits? 1. Viable fungal growth is an established method of contamination assessment. See for example, Ch 6 of the AIHA Field Guide for the Determination of Biological Contaminants in Environmental Samples. 2. Settle plates are used in the assessment of clean rooms and in the microbiological evaluation of cleanliness and biocontamination control. A quick search on PubMed reveals many articles and references on the settling plate or sedimentation technique: - eg: EU Guidelines to Good Manufacturing Practice Medicinal Products for Human and Veterinary Use. - eg: Comparative study of impaction and sedimentation in an aerosol chamber using defined fungal spore and bacterial concentrations paper. - “A high correlation coefficient was found between the impaction and sedimentation methods” - “This study concludes that active and passive air sampling can be used for monitoring the air in clean rooms. For fungal spore detection, the impaction is more efficient, as it is possible to sample a higher volume of air in a shorter period of time”. Unboxing the DIY Mould Test Kit: - What’s inside? - What do the plates look like – before and after sampling? - What paperwork is required - Chain of Custody Who Are These DIY Mould Test Kits Suitable For? - People who need presumptive evidence - This is decision-making evidence - You may need better evidence from an onsite inspection, but this type of data gives you fact-based information to begin working with. What You Must Do to Get the Most Out of Your Mould Test Kit 1. Air testing is better than surface testing since this will reveal what is in the breathing zone 2. Always take an outdoor control 3. Sample from the main habitable rooms. You need to select meaningful Regions of Interest (ROI). 4. More samples are not necessarily better. 5. Sample for exactly 45 minutes for each petri plate. Consistency of sampling method. 6. Place each petri plate on a desk or chair or table 7. Send back soon after sampling – don’t wait and watch colonies grow 8. Recognise there are limitations to testing. Ordering a kit won’t automatically give you all the evidence you need to break your lease, get your bond back, argue with your builder, insurer or landlord or boss – but it will give you evidence you can use to mediate or negotiate an outcome that is reasoned. The whole point of Julius Richard Petri’s 167-year-old invention was to make it easier to cultivate microorganisms. You also have the same tools at your disposal allowing you to culture environmental fungi that could be making you unwell. But to make that connection you need some data and DIY mould test kits give you a great start to answering this question in your own home or office and exemplifies the true definition of science which is: “knowledge about or study of the natural world based on facts learned through experiments and observation” REFERENCES: 1.

What Is Black Mould?

33:483 years Ago
WHAT IS BLACK MOULD? - Black mould is a catch-all term that refers to toxic mould that has been linked to building-related respiratory problems. - The colour of the mould is not the diagnostic. If your wall or ceiling is showing signs of mould and it’s green, then you can’t assume you don’t have black mould. - It’s very common to grow on wood, gypsum and plaster and insulation found on pipes, aluminium foils like wall wrap and wallpaper. This fungus prefers cellulose-rich substrates containing high moisture levels. HOW DOES BLACK MOULD HURT YOU? - This fungus produces a large range of toxins called: TRICHOTHECENES. - These bind to ribosomes that allow proteins to be built from long chains of amino acids. This toxin interferes with protein synthesis. - It’s not the only problem in damp or water damaged buildings. Other factors like the presence of bacteria, cell wall particulates, mycotoxins, non-microbial volatile organic compounds and microbial volatile organic compounds (VOC’s and MVOCs), other proteins and endotoxins can all cause problems for people by different mechanisms. WHAT BLACK MOULD LOOKS LIKE? - Let’s look at it under the microscope. WHAT CAUSES BLACK MOULD? - Water ingress caused by 5 things: (1) Leaks through flat roofs (2) Rising damp (3) Defects in plumbing fixtures and fittings (4) Extreme indoor condensation (5) Weather events including storm damage and floods CAN BLACK MOULD KILL YOU? - Review the infamous case of the Cleveland infant idiopathic pulmonary haemorrhage (IPH) reports. - Official response is NO from the Centres for Disease Control and Prevention. CAN BLACK MOULD MAKE YOU ILL? - Stachybotrys has been linked to a range of symptoms called “building-related illness” and include runny nose, cough and irritation to the eyes and throat. - Controversy about how serious the threat is. - Stachybotrys mycotoxins are divided into 3 structural groups: macrocyclic trichothecenes (e.g. satratoxins), atranones, and phenylspirodrimanes. - They cause strong inflammatory responses. - Your nose might be the first thing that’s affected because it’s exposed to everything you breathe in. RHINITIS is the term that covers that runny nose, the stuffy feeling - that might be due to the common cold or an allergy but might also be due to mould! Low dose, big effect - also linked to neurologic symptoms - Foodstuffs like cereals a very real exposure pathway. For example, the United Nations estimated that 25% of cereals produced worldwide are contaminated by mycotoxins. - Building materials used in your home might also make your home more or less likely to show black mould problems. Green building materials are made from recycled sources. - Now think about that composite timber flooring under your tiling in the bathroom? That’s an example of a green building material that uses recycled content. In a recent experiment from 2017, ceiling tiles, composite board, plasterboard walls were made wet and inoculated with dusts containing fungi to see what would grow after 2-months. They found that recycled or green gypsum board (plasterboard) was dominated by Stachybotrys fungus. - In Australia the thunderstorm asthma event in 2016 has prompted the Government to take very seriously the impact of pollens and mould spores that can be stirred up and distributed by weather events. There’s a new Interim Standard for airborne pollen and mould and this is a welcome addition to the Australian Mould Guideline (2010). CAN BLACK MOULD CAUSE CANCER? - Some research shows that components of the trichothecene toxin could be Group 3 carcinogens. However, Group 3 agents aren’t classifiable as carcinogenic to humans. This is because the evidence of carcinogenicity may be inadequate in humans or inadequate or limited to animals. - BUT: Cancer-related inflammation is considered the "seventh hallmark of cancer"; numerous studies demonstrate that tumors develop and progress within inflammatory diseases. IS BLACK MOULD DANGEROUS? YES - because it’s absorbed from the skin, airways, and intestinal lining. BLACK MOULD EXPOSURE SYMPTOMS - malaise, fatigue, cognitive impairment. Inhaled spores cause chest and upper airway symptoms, fever, reduced white blood cells count and dermatitis. These symptoms typically start 2-3 days after exposure and can last up to 3-weeks. - New research is even linking exposure to Alzheimer's and autism. - Asthma is often an allergic response to mould. REMEMBER - All moulds including black mould grows on wet building materials. Keep your home clean and dry as best you can. Mould isn’t always visible, and you may need an indoor air quality or mould inspection or assessment or other form of testing. If you need help, call in a professional. ★ Follow On Facebook: 👉 ★ Website for BIOLOGICAL HEALTH SERVICES: 👉 ★ Website for DR CAMERON JONES: 👉

Top 10 Toxic Mould Social Networks on Facebook

21:293 years Ago
Who do you trust when it comes to mould? What have other people done? Am I the only one with these problems? Surely other people have dealt with mould and water damage and been successful and put it all behind them? Who will you turn to for advice, acceptance and wisdom? Social networks and health communication may be an important component of a solution that fits your needs. WHY WOULD I WANT TO HEAR ABOUT THIS PARTICULAR TOPIC? Online social networks, social influence and information cascades happen because of two types of influence. The first is PEER INFLUENCE where acceptance of information is dominated by users of the social network who influence the acceptance and consumption of information. The second type of influence is EXTERNAL INFLUENCE where for example the traditional news media introduces ‘a story’. WHY WOULD I WANT TO KNOW ABOUT THIS? Social media engagement is fundamental to increasing the probability of reaching a target audience or being exposed to content you want. Facebook Groups are hot property! In 2018, 1.4 Billion people on Facebook used Groups every month. Closed Groups offer a way for like-minded people to community-build, share information and interact without a gatekeeper and without brand approvals or at least where known brands are in the background and people are at the interface of the dialogue. WHY IS IT IMPORTANT FOR ME TO KNOW ABOUT THIS RIGHT NOW? Facebook is also changing their own rules and is rolling out “health support groups” where it will be possible for patients to post sensitive information anonymously through groups admins. Other groups are: public, closed or secret! WHAT ARE THE FACTS? Before I get into the specifics of the Top 10 Facebook Mould Groups I want to review what we know about social media, communication and misinformation. 1. Content consumption about vaccines is dominated by the echo-chamber effect. The echo-chamber effect is when users or readers are exposed to information inside a bubble that supports their previously held beliefs. This is caused in part by machine learning algorithms at Google and Facebook where information content is tailored to users interests. 2. Echo-chambers explain why social media campaigns that deliver accurate information may have limited reach. 3. In fact, scientifically accurate information may only be effective in sub-groups and may even cause further polarisation away. What I mean here is that introducing dissenting information into a sub group can back-fire and in fact reinforce existing opinions within groups. SEE the original 2018 paper that will be in the references to this livestream 4. Other research shows that TRUST contributes to the success of social groups especially by encouraging people to interpret the actions of others favourably. 5. Some key facts emerge: (a) The likelihood of trust depends on how much they trust the group (b) Smaller, closed groups are trusted more (c) The individuals position within the group can predict trust (d) There are gender gaps - across countries, women tend to have larger networks of close friends than men and female users living away from their home town are more likely to engage in Facebook compared to their male counterparts. WHAT ARE THE CONSEQUENCES OF MY DOING WHAT YOU ARE SAYING? - You will be able to connect with like-minded people instantly. - Exposure to near to real time news and information discovery - SOCIAL can mean “fun” and “enjoyment” - Some risks due to information overload, distraction and procrastination WHAT ARE THE CONSEQUENCES OF NOT CHECKING OUT FB GROUPS? You could miss out on timely and valuable peer-support Consensus thinking in your niche can be subtle and by not joining in, you risk missing out on trends. Post popularity also gives you clues about these trends at work in your community. HOW CAN I USE THIS RIGHT NOW? I’ve done some research using a machine-learning and predictive optimisation tool that analyses all platforms on FaceBook and the results are in… The Top 10 Toxic Mould Social Networks on Facebook (at 24/07/19): 1.

Mould Testing With Spore Traps: How To Measure Your Indoor Air Quality

22:453 years Ago
Do you need to know if your indoor air quality is being affected by mould spores? Has your property been water damaged? Is there a smell? Are you concerned about biotoxins? Covering the what, how and why of spore trap testing. I'll also discuss some real world examples showing you some examples under the microscope. Find out when they are useful and my Top 6 tips for success and some pitfalls of this widely used method. I’ll also be doing a Q&A and links to papers/resources will be provided after the livestream in the description or comments. TOP 6 TIPS FOR SUCCESS WITH SPORE TRAPS: 1. Take enough samples - must have representative data to answer questions about habitability across the home and in regions of interest2. Adequate controls taken - statistical significance3. Samples taken in the breathing zone4. Spore trap data linked to other types of sampling5. Consider destructive testing where there’s a suspicion of hidden mould eg. behind walls6.

What Is Bio-Tape & How To Use It?

20:113 years Ago
Today I’m going to be talking about the subject of Bio-Tape - otherwise known as Tape Lifts or Cellotape Lifts. These are very commonly used in water damage investigations for mould and I’m going to show you how they’re used, some of their advantages, and some of their disadvantages. Q: WHY ARE THEY USED? A: If you see visible mould, how can you measure it? • You could take a photograph, but that doesn’t tell you what fungi are present? • You could take a surface press plate impression - but that’s a whole other topic called Viable Sampling • You could take a spore trap - but that also doesn’t tell you about surfaces, only indirectly try since that measures the concentration of mould in the air. • You could even take a swab sample - but again, you need complex microbiological media to streak the swab across and incubation facilities. ENTER: The Tape Lift. • These are a sticky microscope slide and they look like this Now before we go any further I want to talk a little bit about the Standard for Tape Lifts Called: “D7658-17 Standard Test Method for Direct Microscopy of Fungal Structures from Tape” THE STANDARD 1.1 Uses optical microscopy for the detection, semi-quantification, and identification of fungal structures in tape lift preparations 1.2 Describes the preparation techniques, procedures and how to report the observed fungal structures 1.3 Values are stated in SI Units SIGNIFICANCE AND USE I’m going to show you 3 different use cases: 1. Tenancy mould - proof that there’s a problem 2. Owner was flood affected and her house has been remediated by contractors appointed by her insurer. She’s not happy with the works and we’ve been brought in to do something called post remediation verification. 3. A husband and wife have lived at their property for approx. 8 years. The wife has been unwell for about 7 of those years and they have recently discovered mould growing in their Master Bedroom. BENEFITS/PRO’S: 1. Quick to do and relatively inexpensive 2. Easy to test a range ion different surfaces 3. Test and send to lab - the lab does the hard work CON’S; 1. Potential bias in sampling - you could cherry pick ALL mouldy areas or pick all non-mouldy areas are manipulate the conclusions drawn by the data 2. Species ID much harder when tape is ripped off the surface - causes damage to tiny cell structure. Like ripping off a bandaid. CONCLUSIONS: 1. It should be used as a companion or complementary method e.g. use tape lifts and RODAC press plates in combination for contents testing. 2. If a number of samples are taken from a representative set of surfaces to answer a specific question, the method is reliable 3. Next timer you have need for a mould assessment ask if tape lift testing is available ands is suitable for your situation? I’m your host, Dr Cameron Jones, PhD.

When you go to the Doctor and follow their treatment advice you usually feel pretty confidant in their skills safe in the knowledge that they have successfully graduated their medical degree. You assume they follow procedures and know where to access expert advice and information to help them do their job properly. • But what about when your home or office or personal property has been damaged by unexpected water? • Do you have a valid claim for damages? Is mould a real or foreseeable risk? • How is the building or your home contents going to be assessed OR how have they been assessed? • What criteria will be considered? What lens will you assessor or inspector use? Now if you’re watching or listening to this - I’m assuming you want to know if there are some objective methods or approaches used by the water damage and restoration industry; and if so what are they and where do you get them to read yourself?

Can Mould Grow On Or In Bricks & Concrete?

12:133 years Ago
Think that mould only grows on bread, or on rotting fruit or if it does get inside your home - doesn’t it just live inside your air conditioning ducts where condensation can form, or if there’s been a flood or unexpected water ingress then it might grow on damp wall linings like gyprock plasterboard or on soft furnishings like backpacks or curtains? This week, I’m wanting to talk about mould growth in extreme habitats like stone and mineral building elements. Think it can’t happen? I didn’t? I thought the only time microbes attacked walls was on really old ones where cultural artefacts like murals in churches or in caves become damaged. This phenomenon is called biodeterioration. However, I want to share with you some results from an inspection I did where we found mould growing not just on old plaster, but behind bricks, in old mortar joins, behind and between excised bricks and when we cracked some of the bricks open, there was even mould growing inside! Efflorescence - are those fluffy salt deposits that can occur in humid environments and appear like white or yellow powder or finger-like crystals. These are not mould, but are chemical patterns left after mineral dissolution. Fungi can grow on this low organic nutrient material, especially if there’s available water. Now imagine what happens to your brick work when it gets wet and you see efflorescence. That’s a sign of fungal attack. If you have rising damp, your have slow biodeterioration going on indoors. Health concerns were raised by the authors of this study about breathing in the crystalline salts by residents where terrazzo tiles are breaking up. This type of dilapidation happens eventually in the built environment. What about concrete? Typical fungi to those seen in the contaminated bricks include Aspergillus fumigatus and Penicillium brevicompactum. When concrete specimens were inoculated with these typical fungi and tested for stability and examined under a scanning electron microscope…do you know what they saw and found? The fungi induced: * Calcium release from the concrete * If the concrete was wet then they saw more rapid calcium loss compared to drier concrete * After 28days of growth with Penicillium, the stability of the concrete showed a 1% loss. Lets revisit the mould in brick examples… What do you think is going to happen to your house if there’s a fire and the whole house is saturated? How is your remedial company going to get the mould and spores and biofilms out of the bricks, inside the bricks and between the mortar joins? Even though we don’t have all the answers, next time you see some salt crystal efflorescence, think about the hidden network of mould mycelium growing inside the walls of the house from where the brick samples came from and ask yourself: would you feel safe living there? NEXT WEEK: What Mould Remediation Standards Are Available? Which should you use and why are there different published Standards and Guidelines? I’m your host, Dr Cameron Jones, PhD.

How Mould Fits Into The Triad Of Disease, Illness & Sickness

10:094 years Ago
I’ve decided to do a weekly live stream about public health and wellness. You see, I’m an environmental microbiologist and I help people take control of their home or office environments and help people reduce their exposure to mould and water damage in order to improve their health. Why do I do this? Well, people call me every day with their water damage issues and I’ve done a lot of building inspections. Last count I was at approx. 3000 inspections and/or lab reports…so I’ve seen a lot of water damage and met a lot of people all experiencing mould from different perspectives. So….I want to share my knowledge with you. Therefore every week, I’m going to zero in on a hot topic about water damage and mould using Live streaming - I want to do regular Q&A’s and I’ll also be doing interviews and having guests on the show for online streaming as a duo or maybe even as a panel. So, today I want to offer some tips for better understanding my industry… But first: I want to briefly highlight my show health disclaimer: This livestream is informational and educational only and not specific to you and intended to help you with your own personal wellness efforts but you should consult your own qualified medical practitioner before adopting or following any of the suggestions or strategies I may express or discuss. I am not offering medical advice and the content I deliver is educational and for entertainment purposes only. Now with that out of the way… Mould is very real. I’ve put a few references into the show notes and these are in the description below the video or audio. Here’s an example: A previous client called me up yesterday and I will recount parts of her story to illustrate my points. Not everyone believes in biology, let alone microbiology which is the study of bacteria, yeasts, fungi, virus and some algae. There are about 100,000+ known fungi described in textbooks There are really about 4-5 million different fungi based on genetic sequencing About 300-600 known fungi cause disease in humans. Fungi reproduce through spores and it’s these spores that are allergic, possess mycotoxins and if the concentrations are high enough, produce microbial VOC’s that are often toxic. This lady is suffering an extreme mould reaction. I’ve seen the spore trap results under the microscope. Levels of 10,000 - 40,000 and higher spores per cubic metre of air. Long term water damage… Her husband doesn’t believe her. Her husband thinks she needs psychiatric help. She is beside herself. On the one hand, she’s sick. On the other hand, there’s great lab data confirming her home is full of mould. The home was known to be water damaged during a recent large-scale renovation. BUT her husband can’t see the mould, and he feels fine. She on the other hand has many of the classic mould symptoms. Her own doctor has confirmed with a mycotoxin test that she is indeed showing high levels of mycotoxins in her body. Then she moved and her symptoms became manageable. However she called me because her husband brought items from the water damaged property into the house and she’s reacted to them… This brings me to the central topic of this live stream: How the emotions of sympathy and anger affect decision-making? There’s a triad I often see about mould and adverse health and there are 3 interrelated concepts you should be aware of if you or a loved one or family member is exposed to mould and these are: 1. ILLNESS - this is where a person experiences a loss of health and has some symptoms. It’s a first person perspective. 2. DISEASE - this is where a person calls for professional help and the condition is diagnosed by a medical expert (doctor, allied health practitioner, etc). It’s a professional perspective. 3. SICKNESS - this is where a person takes on or is given a social role about the condition. It’s a societal perspective. This triad gives rise to a very real set of tensions…

Indoor mould inspection where the occupant claims she has contracted pneumonia

12:115 years Ago
If you ever wanted to know what a typical indoor air quality and mould inspection involves, then this video will show you. The occupant and her family have lived at this rental property for several years. Currently the mother and her son are extremely sick. She is being treated for Aspergillosis pneumonia. She has been coughing up blood and she tells me her lung scans show classic signs of infection. She is too scared to come back to the home. The landlord and property manager have engaged me to perform a comprehensive indoor air quality and mould inspection. I am told that an evaporative airconditioner has possibly been badly installed or serviced and a large volume of water has been inadvertently sent into the roof void. The aim of this inspection is to collect evidence to see if there is a link between the indoor mould spore levels and the airconditioning. This video shows what an inspection of this type should look for. This video will be of interest to persons who think they may have been exposed to toxic mould in their home as well as those persons with an interest in allergic bronchopulmonary aspergillosis and similar conditions. Interested readers will find this recent paper from the literature of interest: Asthma and Fungus: Role in Allergic Bronchopulmonary Aspergillosis (ABPA) and Other Conditions.

How To Protect Yourself From Mould After a Flood

1:205 years Ago
Massive flooding most recently in Texas will inevitably lead to major mould growth inside homes and commercial properties. As first responders prepare to provide emergency assistance, I want to share this short post highlighting the minimum requirements for personal protective equipment (PPE). All persons entering potentially mould contaminated houses should protect themselves using this 4 step process: 1. Gloves 2. P3 half face respirator 4. Goggles 3. Disposable coveralls Mould will begin growing wherever there is a water source and a food source. After a flood, this means, potentially every porous element inside a house can become mould contaminated. If you are attempting a salvage operation you must take steps to protect yourself from skin (dermal) contact as well as inhalation risk. Once mould is visible to the eye, there will be massive levels of spores that are microscopic, and can’t be seen, but are still present. Mould also produces mycotoxins that in some cases are carcinogenic and at the least, many are known to be neurotoxic, so be careful! The following articles cover these topics in greater depth. - Review of health hazards and prevention measures for response and recovery workers and volunteers after natural disasters, flooding, and water damage: mold and dampness. - Impacts of flood damage on airborne bacteria and fungi in homes after the 2013 Colorado Front Range flood. - The impact of flood and post-flood cleaning on airborne microbiological and particle contamination in residential houses. - Comparison of nanoparticle filtration performance of NIOSH-approved and CE-marked particulate filtering facepiece respirators.

Introduction Video Dr Cameron Jones for Steemit

1:345 years Ago
This is my introduction to the Steemit Community and I want to tell you a little about myself and why I intend to contribute to this platform. I’m a scientist who lives and works in Melbourne, Australia. I run my own lab which focusses on indoor air quality and mould inspection and sample analysis. It’s really busy and we tend to work for insurers, property managers, homeowners and tenants, and increasingly, medical doctors who refer their patients to us where they may be suffering from adverse health impacts caused by poor indoor air quality or mould. Water damage to buildings is a leading cause of mould contamination. So, many of our clients come to us because they have had a history of leaks or flooding or just general building decay that allows moisture to enter unexpectedly. When this happens, and over time, mould can grow. The spores can then elicit upper respiratory tract symptoms, wheeze, coughs and asthma and other toxicities. That’s why my lab exists - to measure these building specific factors and help the remediators or the owners engage trades to fix the problems properly and professionally. Anyway, I also love applied mathematics and was one of the first researchers bridging cryptographic hashing functions and microbiology. I wrote a few papers on this before some of that work was taken up into a Patent. It’s for these reasons, that I’ve decided to join the Steemit community since I believe the crypto space is going to explode with novel and unexpected applications bridging disparate disciplines like maths and biology and many other areas of science. I’m active across other platforms and you can check my work at the links below. Bye for now, Cameron Link to this video on Steemit DTube:!/v/drcameronjones/tuaa77lt

How I test a home for mould where there is condensation and asthma issues

3:355 years Ago
In this video I take you behind the scenes while I do an inspection of a property where the occupants all have serious asthma-type reactions. This Family are in community housing and report that their symptoms have been getting worse. This has coincided with noticeable window condensation especially over winter. All the bedrooms have large windows and the Family complain that no matter how much they heat the home, it's always cold and the windows drip with condensation. They also have seen profuse green and black mould growing on the windows, window frames and blinds. Because this is community housing, I have been provided with a maintenance request to inspect the property and take samples and provide a report so appropriate action can be taken. On arrival, it's obvious the home is somewhat neglected but the occupants keep the home neat and tidy. It was a cold morning when I did the inspection, and I witnessed first hand the heating being 'on' but condensation droplets on some of the windows. The best way to test a home for mould is to sample in several ways. 1. I do this by measuring the cumulative particle size dynamics for particulate matter indoors versus outdoors and also the inter-room variability (PM2.5 and PM10). 2. I then test all rooms for spore concentration using air-o-cell spore traps. These have a sticky microscope slide inside the cassette that traps a known volume of air and can then be analysed under a microscope. After staining, the spores and other debris are easy to see and measure and identify. This maps out the exposure hazards (if any) for mould and pollens and other particulate matter inside this home. 3. I then repeat air sampling to petri plates to see what grows. This is called viable sampling and is very useful to recover fungi that are viable indoors. This test is a bit like a medical doctor swabbing your throat and culturing it out. In a similar manner, I work out what's growing indoors. 4. The next method to test surfaces uses swab sampling - again to petri plates for obvious signs of mould - like in this video where there is mould growing on the blinds and internal windows. 5. The next important test is to use infra red thermography to look for building-specific reasons why there might be cold or hot spots in this home. Infra red revealed thermal bridging in this home and easily shows the temperature discontinuities. This highlights the very poor insulation in this home. My recommendations for this home will include: steam cleaning of all the internal windows and window sills, removal and replacement of all of the internal blinds with new, installation of superior roofing insulation after removal of the old, dirty, insulation. Repair of the roof and installation of a dehumidifier. It is likely to be hard to stop the condensation without changing the window frames and changing/increasing the window thickness - but these methods detailed above will help. The home should then be monitored for a reduction in condensation and mould over the next 3-6 months and other measures implemented as required. The takeaway message from this video is that if your home has visible mould and or condensation on internal windows, this could be affecting your health and impacting on asthma-type symptoms. If you get your home tested, make sure that every room is tested. Make sure that more than one method is used (i.e spore traps and viable testing and tape lifts) and make sure that environmental parameters like infra red thermal imaging or contact probe moisture meter readings are collected. The purpose of an indoor air quality and mould inspection should be to map out suspect contamination is every room of the house, including the roof void and subfloor. If you receive a mould inspection lacking this level of detail, then, you should insist on the inspection being repeated by another more competent inspector. Environmental health works because of quality data, and recommendations are only as good as the data on which interpretations are made. If you'd like to discuss your particular indoor air quality or mould issue, then feel free to contact me at: or at Dr. Cameron Jones, PhD Biological Health Services

Behind the scenes look at what post remediation verification is and why it’s important

2:125 years Ago
In this Snap story I take you behind the scenes into a commercial shop that has suffered flooding and mould. I show you why I'm here and the process of Post Remediation Verification, or PRV, which is the technical term for the procedure to evaluate the success (or failure) of the mould remediation/cleanup exercise. Because this is a commercial tenant, there are concerns that the cleanup works performed by the landlord have been successful and that there are no remaining risks from mould, spores and mycotoxins. After all, no one wants to be exposed to sick building syndrome. As part of the testing process, readings were taken “BEFORE” remediation began to establish the baseline mould and indoor air quality levels. Readings are then taken “AFTER” remediation, enhance why this type of testing is called “Post Remediation Verification”. This always needs to test every room in the building that was likely to have become affected by the flooding and/or mould events. It’s also very important that all tests are performed with adequate controls. For this shop there were areas that were open to the public, some stock areas and then areas that only staff use as well as staff offices. Each area will usually have different usage patterns and these should be captured in the report for the building, as well as comment on the likely and foreseeable impact of mould and spores on the occupants. It’s also a good idea to always take adequate control readings, especially in a city environment where the outdoor readings will likely contain elevated levels of diesel exhaust particulates. The point of this exercise is to evaluate the shop for mould spores, rather than any of the other pollutants! I always insist that the BEFORE testing uses at least three different methods to quantify (measure) the levels of mould after a folding event. This is a good way to make sure that the building has been comprehensively tested and also means that the success of the remediation can be determined on a room-by-room basis. The three or four methods I normally always use are: (1) cumulative particle size dynamics, (ii) spore trap analysis and (iii) viable testing to measure what fungal colonies are present in the air and (iv) on suspect surfaces. As required, I often also test using (v) tape lifts. This is the only way to ensure that the inspection results are rigorous and comprehensive. I all to often see reports done by other inspectors that only take a handful of samples, or sample in areas unlikely to have an impact join the health and safety of the occupants. IN some cases, these reports are self-serving - in that sometimes the purpose of the report is to show that the remediated has done the job -when in fact, the work is of poor quality etc. The only way to safeguard yourself against poor quality mould remediation is to insist on a comprehensive inspection showing the BEFORE and AFTER data and making sure all samples are a like-for-like comparison. This is just basic science. So, if your home or shop has been flooded, and there are potential health implications for usage of the building, then it’s in your interests to insist on quality inspections for both the pre-remediation as well as the post-remediation verification. In Australia, we follow the Australian Mould Guideline (2010). This sets out the threshold scale for mould colony counts and spore trap interpretations. The remediator needs to follow the: Australian Mould Guideline. 2nd Ed, 2010 as well as the ANSI/IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration, 4th Edition, 2015; the ANSI/IICRC S520 Standard for Professional Mold Remediation, 3rd Edition, 2015 and the ANSII/IICRC R520 Reference Guide for Professional Mold Remediation, 3rd Edition, 2015 for how to perform mould remediation. These documents combine to explicitly say what should and should not happen as part of the remediation works. It is imperative that scrutiny be leveled at the remediator, since its not sufficient that the remediated claims to be ‘trained’ or that they ‘follow the Standard’. It’s vital that their work is rigorously assessed. This is where I see so many failures. Therefore, only accept Post Remediation verification reports that clearly show the “Before” and “After” results. This way you can minimize your exposure to poor quality mould remediation work and minimize the risk of cover-ups. This is also the only logical way to ensure occupant safety and maximize the likelihood of re-occupying a building after a flood where mould levels are back to normal. Follow my Snaps for more mould inspections and health tips and tricks about mould and mould exposure and how to professionally assess the risks.

Case study showing how the roof void and dirty insulation is sometimes the hidden mould area

2:025 years Ago
This Snap story highlights the fact that many people who complain of mould illness with no history of water ingress or flooding are actually being poisoned by their roof. The Family got me in because their children were experiencing asthma-type symptoms after spending any length of time indoors. They knew of one water leak above the front door entrance, but apart from that they thought the home was a-ok otherwise. You can see me using a handheld particle analyser to measure the particle size dynamics (cumulative mass) across each of the different rooms and versus outdoors to quantify the indoor air quality. This is important to work out what might be going on from an indoor pollution, or sick building syndrome perspective. I also take a swab sample to PDA agar to culture from the water stained section of cornice above the main entrance. After 3-7 days it is possible to differentiate into Genus many of the fungi that grow. As well, we get valuable information regarding the viability of any obvious water stained areas. This also confirms if the water leaks are old or new in some cases. The Snap story then shows what the inside of the roof void looks like. You can see the blow-in roofing insulation. This material is granular or friable and easily becomes airborne. In this particular home, the roof was a tiled roof. These types of roof admit lots of air and it's easy to se daylight around many of the tiles. In these circumstances, if you can see daylight from inside the roof void, then rainwater can see inside your roof space when it rains. If the roof void insulation becomes wet or damp, then in combination with air currents, the insulation material can easily become airborne. Micron and sub-micron sized particulates (of roofing insulation, cell wall debris, spores, endotoxin containing dusts, fibers and debris, etc) then enter into the habitable parts of the home underneath via downlights and other ceiling penetrations like vents. The following article from the Annals of Occupational Hygiene confirms that roofing insulation of the type shown in this Snap video is a high risk factor for respiratory distress, Interested readers can consult the original articles: 1.

You can see very clearly in the video that once the PM5 and PM10 micron size range is measured that the roof void is heavily contaminated and that this material becomes effortlessly airborne simply through ambient air currents. It is this fine particle material that enters the habitable parts of the home and is likely making the children sick with asthma. It is very satisfying to perform indoor air quality inspection like this and easily be able to locate the problem areas. Its also an interesting case study, since the family got me in to check the mould above the front door - but the main problem was affecting the whole of the home, and was localised inside the roof void with the blow-in insulation. The family confirmed that it had been in there for years! The solution to a healthy home is therefore to replace the existing insulation and then manually HEPA vacuum out the roof void before installing new insulation.

Case study showing how ERMI fails a client who needs definitive answers about mould inside her home

1:185 years Ago
This Snap story concerns a Family who went to their local GP because their daughter was sick. It turned out that she was experiencing chronic fatigue and after finally getting to see another specialist was recommended to do the ERMI. The ERMI stands for the Environmental Relative Moldiness Index. This link shows you that the ERMI is not approved for use by clients like this Family and the EPA who administer the patent for the ERMI don’t endorse it for use, let alone, use by medical practitioners and is for RESEARCH USE ONLY. See: The big problem with the ERMI is that at least for this Family, only one sample is taken from the house. This means that even for a home that does show a mould problem, the single sample is unlikely to reveal any new information about the WHERE and HOW MUCH the mould problem is? Also, the fact remains that a water damaged home and measuring the mould content is already easily done using (i) spore traps or (ii) viable sampling or other surrogate indices such as (iii) micron and sub-micron particle size dynamics or (iv) mycotoxin assessment. It is true that the principles of ERMI make sense. Who wouldn’t want a test that claims to classify your home against the 36 most representative mould types. The problem is that without doing ERMI on EACH room in your house and against valid outdoor controls, you have one data point and a whole host of unanswered questions. This Snap story aims to highlight how a simple walk through of the property by an experienced assessor can uncover scientifically valid signs of water damage and collect representative data for the WHOLE house without missing any rooms or areas. This is the only way to comprehensively examine any indoor living environment for the presence of mould when health issues are at stake. Not shown on the Snap story is the fact that I also measured the particle size dynamics for every room as well as took spore traps for each room and an outdoor control. It immediately became evident that two rooms of the home were affected and the spore traps were also in one-to-one correspondence with the particle size scaling (determined once I got back to the lab and could examine the air-o-cell cassettes under the microscope). The infra red data also highlighted fundamental building defects of the home. Taken together this information allows the Family to: (i) isolate those areas that require remediation, (ii) determine what items of personal property might need remediation, (iii) work out which rooms or areas need building maintenance, and (iv) make some decisions regarding how the Family occupy (or don’t) those areas that have been found to be contaminated. The level of mould contamination using air-o-cell spore traps showed a ten-fold difference between the air quality indoors versus outdoors and easily pinpointed the two problem rooms. Notably for the Family, their daughter used both rooms regularly and there were easy correlations between roofing defects and known rising and falling damp issues affecting the daughters bedroom. Notably, chronic fatigue is an autoimmune disorder and has a strong correlation with environmental toxins like mould. Unfortunately the ERMI only confused BOTH the medical practitioner and the Family who still needed to get my Company involved to pinpoint the actual problems and provide recommendations. There’s a reason why the EPA don’t endorse the ERMI except for research and you should think twice if you are offered this test - since it measures something - but probably not what you need to solve your mould problem - and isn’t that what mould assessments are supposed to be all about.

Behind the scenes investigation into water damaged framing timbers inspected for mould

4:025 years Ago
This video reveals the "before" and "after" results when I inspected a basement that had flooded. The owner was concerned when he went downstairs into his basement and discovered that it was flooded. He was worried about exposing himself and his Family and children to: mould, mould spores, mycotoxins, mVOC's and micron and sub-micron sized cell wall fragments that he was aware could elicit an immune reaction and caused adverse health impacts. He had read all about black mold and the potential respiratory and cognitive impacts from mould exposure and didn’t want to suffer from mould illness or have his new home turn into a building that was going to cause a sick building syndrome problem. He told me, he’d been reading about mycotoxins and said that he had seen the mould quickly grow onto the timber frame when the builder alerted him about the flooding event. He said he Googled “mould” and “black mold” and up came lots of results for "chronic inflammatory response syndrome" or CIRS. He said he and his wife were going to be trying for more children and this basement was going to double as their home gym - so they didn’t want to be breathing in mould or spores or mycotoxins that could make them sick of give them an allergic response. How did this happen? Apparently the builders had inadvertently switched off the pump that controls water levels. This meant that the basement flooded for several days before being discovered. The owner insisted on some of the walls being cut away. When the builder reluctantly did this, on removal of some of the plasterboard, visible mould could be seen. The owner was angry that this happened, and the builder assured him that he would deal with the mould problem. However, to make sure that the basement was properly remediated, he engaged our Company to perform an independent mould and air quality survey. It was quickly discovered that only some of the walls had their plasterboard removed, and there was remaining wall insulation that also appeared visibly mould contaminated. It turned out that the builder went to the hardware store and bought a spray-on liquid disinfectant that he sprayed onto the mould affected framing timbers. This is the condition in the first part of the video where I am taking spore trap and viable swab samples. Not shown in the Snap video is the tape lift sampling that was also done. In the next part of the video I show how a handheld laser particle counter is used to take outdoor control readings of the cumulative particulate matter levels. This is useful for measuring the indoor air quality in terms of particulate matter to show the indoor versus outdoor and inter-room variability for this home. In the third part of this video, I discuss some of the results for the basement showing that the spore traps still reveal high levels of mould spores and I discuss the fact that a liquid disinfectant in this example has failed to render this basement to a 'normal mould level' condition. Not shown are the viable swab results and the tape lifts which revealed high levels of surface bound biofilm and active mould growth. I end the video with a warning to engage your own independent inspection for mould to establish that any remediation works have in fact been successful. This is called post remediation verification (PRV) and is very important to work out if the home is likely to be healthy after the works are completed. In conclusion, this PRV failed and the builder needed to engage another contractor to perform media blasting of the timber framing with dry ice under negative pressure and HEPA air extraction and suitable barrier containment. Only then, did this basement finally pass another set of tests comparing the 'ingoing" condition with the 'failed remediation conditions' assessed against the final step 'after media blasting'. Although it took more time, the owners could be confidant that the remediation returned this area to a 'normal mould' condition and then the plasterboard walls were re-instated after new insulation went in and the basement was then painted ready for occupancy.
