Science is all about observation and forming hypotheses to answer questions. For scientists like myself, Iâm interested in how the environment affects health, and specifically, how water-damaged buildings and exposure to poor indoor air quality can affect quality of life. For this week on The Mould Show, we're going to be talking about fungal mycotoxins and myalgic encephalomyelitis termed ME for short and chronic fatigue syndrome (ME/CFS).
The reason I've chosen this topic is that I've met a family whom I've now done three separate mould inspections for. Why this is unusual is that the symptoms experienced by the female occupant and her daughter are classic ME/CFS symptoms. Across all 3 of the different properties hidden mould problems were discovered. That information in itself was useful for this family and helped them to break their lease due to the fact that there was verified mould present. However, that's not the point of this podcast and even the positive mould confirmation as an environmental trigger didnât help the mother and daughter from understanding why they reacted so strongly when indoors. They thought they were going crazy, since how could 3 different properties cause them so much trouble? They couldnât understand why some buildings caused no issues, and the 3 theyâd chosen to rent all set them off?
This has bothered me all year. I know mould is a huge issue for some people â but what exactly might be going on for THIS family?
A very interesting article on Substack focuses on his experience with chronic pain and ME/CFS and how after 25 years of suffering, he discovered by chance, following a recommendation from a friend to read a book that talked about the connection between ME and chronic fatigue syndrome and mitochondrial dysfunction. So that is the true focus of the topic today.
⢠Could exposure to fungal mycotoxins be the reason why they were tired and experiencing pain?
⢠Could this be the reason youâre tired? Is this another aspect to environmental illness?
⢠And could this be classified as Myalgic Encephalomyelitis or Chronic Fatigue Syndrome (ME/CFS)?
⢠Are there any patient-specific tests to verify ME/CFS or mould exposure and what can be done to alleviate the symptoms?
Firstly, let's define what ME/CFS is. There are three core symptoms + at least one or more other symptoms which include:
1. an inability to participate in routine activities that would have been possible before becoming ill and that lasts for greater than six months.
2. the fatigue which is also a primary symptom tends to worsen after physical, mental or emotional effort.
3. and does not resolve after sleep, termed âunrefreshing sleepâ.
Other problems include:
a) an inability to concentrate or memory impairment and/or
b) something called orthostatic intolerance. This means that when people stand up, they feel lightheaded or dizzy and can even faint.
The family that moved into those three different properties all complained that after a few days of occupying the mould-contaminated building the wife especially experienced episodes of unexpected fainting and collapsing into her husband's arms.
Those 3 inspections coupled with reading the Substack article led me to investigate further whether there was any published literature, focusing on exposure to fungal cells or their mycotoxins in the ME/CFS literature.
Very recently a publication appeared in the International Journal of Environmental Research and Public Health that has looked at exactly this topic. These scientists looked at the levels of Aspergillus toxins like aflatoxin, ochratoxin, and gliotoxin in the urine of 236 ME/CFS patients who had a known exposure to mould from water-damaged buildings.

This week on The Mould Show we're going to be looking at the gut microbiome and in particular some emerging research that is showing that the diversity of microorganisms found in the gut may be linked to different immune responses and may even affect the pathogenesis of conditions like multiple sclerosis, MS. I'll be reviewing two of the dominant papers in the MS literature around gut microflora and looking at this concept of species diversity. In these papers the scientists looked at the number of different microorganisms between healthy controls and MS patients. Multiple sclerosis is a neuroinflammatory autoimmune disease known to affect two and a half million people worldwide with most patients experiencing what is termed relapsing-remitting Multiple Sclerosis which as the name suggests shows periods of stasis punctuated with symptoms but overwhelmingly moves towards more frequent symptoms as the disease progresses. There are currently no known treatments for MS. However, there is an abundant literature showing that healthy lifestyle factors such as no current smoking, a healthy diet regular exercise and maintaining a low body mass index all help reduce symptoms. The two papers we're looking at today ask the question: Are there some fungi that can be measured in the gut that are correlated with MS and healthy controls? Essentially, what is the role that microbiology plays in MS?. These two papers strongly suggest that bacterial and fungal diversity is indeed connected and can differentiate healthy controls from MS patients. This research is exciting because it offers the opportunity not only for individualized testing as a risk predictor, but also the opportunity for individualized dietary modifications to be made to change the composition of the gut microflora. Both papers determined that fungi like Candida, Epicoccum, Malassezia and Saccharomyces all seem to show statistical relationships that could be a value to predict or at least classify individuals into different risk categories. Interestingly, when we drill into the literature and look at the species diversity for Saccharomyces which is a typical yeast found in breads and grains there is another set of literature that has looked at the gut microbiota and the day 28-day mortality for critically ill patients admitted to hospital. Of course, many of the underlying reasons for hospital admission includes chronic lung disease, chronic heart disease, immunosuppression, active cancer and acute kidney injury. Nevertheless, when sampling was performed, they found clear evidence that species diversity in the gut was predictive for which patients survived versus those that died? So, what to make of these facts? Well, there is an opportunity to look at what readily available compounds might be used nutritionally or therapeutically, to mitigate, delay, or reverse these diseases? One of the compounds being actively researched is called Astaxanthin and is commonly found in shellfish and lobsters and green micro algae. Itâs been shown to not only possess anti-microbial or antibiotic type activity but there is emerging research it can be used for a range of neurodegenerative diseases, including stroke, multiple sclerosis, Alzheimerâs and even conditions like chronic fatigue syndrome. This research into use of astaxanthin suggests that even if it cannot be used as a topical anti-microbial (due to high dosage), it may exert its beneficial effect by altering the composition of the gut microflora at lower dosage. Other elegant research has looked at how astaxanthin has been able to protect the myelin sheath in Multiple Sclerosis models in rats. This research strongly suggests that astaxanthin exerts its effect because they help reduce inflammation and oxidative stress. We can only hope that more research into the therapeutic effects of natural compounds like astaxanthin may lead towards wide-spread use of targeted dietary modifications.

Imagine that at your workplace - you move to new offices and these offices are sited partially below ground level. Within three months of moving into the new offices, every person who works there has started to suffer from symptoms that consistent with exposure to a water damage buildings and are reacting to the microbes and moulds that are commonly found in these environments.
When the symptoms became unbearable, the office staff started looking for answers. This week on The Mould Show, I'm going to be reviewing the research results that carefully examined each of those office workers to work out two things:
Firstly, was the building contributing something toxic that the workers were being exposed to? And secondly, how could this be best measured by the medical doctors who were involved?
This publication looks at whether or not immunosuppression and adverse events can be measured. And if so, how does one go about doing this? This publication appeared on the 21st of January 2022 in the Journal of Fungi: Toxic Indoor Air Is a Potential Risk of Causing Immuno Suppression and Morbidity-A Pilot Study.
What the scientists did was examine both the patient (that is the occupants of the workplace), and they also looked at the building to see what type of toxins and microbes could be detected.
The purpose of the research was how to prove causality between the symptoms experienced by the workers and exposure to the toxic indoor air. But the scientists weren't satisfied with just using microbiological technique to measure for mould, because it's well recognized that even though these tests are very sensitive and accurate to measure mould spore levels in the air - they can often miss the breakdown fragments of microbes that grow on water damaged buildings.
And therefore, this very exciting research from Finland has implemented a new method to assess toxicity indoors, which looks at collecting condensed indoor air water vapour and test that. Now what does this mean?
Well, essentially, they have devised and patented a method of rapidly collecting water vapor out of the air but again, how did they do this?
The Finnish scientists used three toxicity test methods to see how the indoor air might be compromised. The first one was to use THP-1 macrophages. We cover the other two cell, lines in the podcast.
But what about all those people who are working in water damaged building interiors? We know if they're being exposed to particulate matter, like mould spores and cell fragments, from typical indoor air quality tests like spore traps, bio tape lifts or direct microbiology from the air or surfaces onto Petri plates. But many of the mycotoxins can also be measured in urine? Thanks to this breaking research, there are other, new biomarkers like mycophenolic acid â which is tested from the water vapour indoors.
In turn, what do you think the contribution is to adverse health from mycophenolic acid exposure? The Finnish data shows that mycophenolic acid reduces immune function and the other types of in vitro tests showed that macrophages activity is reduced and that mitochondrial activity is increased, but also that bore sperm motility is interfered with.

If you're dealing with water damage building interiors, or just wondering what is the best way to clean textiles and clothing that might have become mould contaminated - you might be thinking, why can't I just put them all into the washing machine? Your next question might be: is there something I can do to the washing cycle that will help reduce the population of any germs that might be on those textiles? The answer is yes, there is an optimal way of washing your clothing to remove specific germs like classes of fungi that cause skin and nail infections. These fungi are termed dermatophytes and are superficial fungal infections that colonize the skin, hair or nails. This group of fungi thrive in moist areas of the skin and are easily transferred to clothing and towels and they are also found in soil. The statistics around dermatophytes report that 20 to 25% of the world's population is currently infected with a dermatophyte fungus. A paper that was published in late May 2022, looked at whether you could freeze material contaminated with dermatophyte fungi, or heat them up in a laundromat or domestic dryer, or whether it was best to wash them â and if so, whatâs the best way to reduce the viability of these dermatophytes? This is an interesting question because although dermatophyte fungi are specific causative agents of skin, hair and nail infections they nevertheless represent a class of fungi that if we understand how they respond to the washing cycle - then this could extend to other types of fungi found in the home, on the floor, or on porous personal items of personal property that might benefit from being washed. So the central question of this live stream is: hot cycle versus cold cycle versus heat drying versus freezing - which is better? To answer this question, I'm going to summarize the key findings of a paper that came out in the Journal of Fungi which looked at how to test between these different treatments. What the scientists did was deliberately contaminate gauze pads with three of the most common fungi that affect humans (Trichophyton tonsurans, Trichophyton rubrum and Trichophyton interdigitale). We know the effects of these fungi when they attack feet and other moist skin areas and cause, for example, Athlete's Foot. We should also respect the fact that these fungi are easily transmitted. Think â of contact with infected individuals or even skin contact with inanimate objects like flooring. And so what the scientists did was they deliberately infected small gauze pads and then cleaned them in different ways. The. They looked at the recovery rate for the dermatophyte fungi. Successful cleaning meant there were no fungi recovered. The first treatment looked at how temperature and cleaning time impacted on fungal recovery. The next question for the washing machine method was whether adding detergent helps? Another cleaning method looked at whether freezing the textile gauze pad could kill the fungi? The results are compelling:â˘Low temperature washing for example, at 40 degrees Celsius for 100 minutes with or without detergent did not reduce the viability of Trichophyton fungi. â˘Increasing the temperature to either 60 degrees Celsius or 90 degrees Celsius for either 100 minutes or 150 minutes resulted in the loss of viability for Trichophyton fungi. â˘The higher temperature was effective with or without detergent. â˘Unfortunately, heat drying the contaminated material in either a domestic machine or a laundromat machine for anywhere from 10 minutes to 150 minutes, did not reduce the population viability of Trichophyton fungi. â˘And somewhat counter-intuitively, it was not possible to freeze the fungus and cause it to stop growing even if freezing was carried out for one day, two days, or even seven days â the persistent viability of the Trichophyton fungi was preserved. The take-home message, therefore, was that domestic washing machines with or without detergent are hig

In Australia, we're currently suffering from torrential rain all along the east coast, affecting Queensland and New South Wales and potentially moving towards Victoria. Regardless of where you're living, unexpected water damage and mould may be a new problem for you to begin dealing with. This live stream and podcast will focus on how to deal with mould and water damage affecting paper documents. We can all imagine sodden books and libraries underwater, but I'll leave that problem for the archivists. This show segment will focus exclusively on how you can deal with mould contamination of paper documents. To do this, Iâll review a recent paper that came out that looked at how to sterilize paper during a crisis. The authors compared two types of sterilization methods called (1) gamma sterilization which uses radiation to perform cold sterilization and (2) dry heat sterilization. Why this paper is interesting is that all of us have access to dry heat using a convection drying oven.
The scientists performed several types of tests looking at the efficiency of gamma radiation versus dry heat. They discovered that gamma radiation inactivated 100% of the test organisms, including fungi and gram-positive and gram-negative bacteria but what about the efficacy of dry heat? The scientists looked at three temperatures: 100, 150, and 200 degrees Celsius for 15, 30 or 60 minutes. They also looked at the impact of two different sterilization techniques on the structural integrity of the paper using scanning electron microscopy. When we focus only on fungi, (because bacteria are easier to kill) it was shown that a conservative temperature of 100 degrees Celsius for 15 minutes achieved a 97.1% inactivation. This also had the lowest comparative impact on the paper structure.
Obviously, other methods of water damage restoration indoors such as increasing ventilation to provide additional air circulation or the use of a dehumidifier are also valuable methods of dealing with water damage.
The take-home message from this paper is that a convection oven can effectively disinfect and nearly sterilize water-damaged papers using a conservative time and temperature of 100 degrees Celcius for 15minutes.
I hope this information helps any persons dealing with mould contamination of paper documents.

Many people ask me the question: can you really get sick from spending time inside a water-damaged property? Or another related question: Does mould really make people sick? Sometimes I even get questions along the lines of: I can understand why people might not like the smell of mould or even its visual presence, but surely, a little bit of mould can't hurt you?
If you've ever been part of these conversations, and want definitive proof that mould can in fact, cause serious problems for occupants then this live stream and podcast is for you. A paper came out at the end of 2021 in the Journal of Hygiene and Infection Control, discussing the situation for a family of five, who developed severe health problems after spending six years inside a water damaged home. Your first reaction might be: why did they stay six years? For many people, this is unavoidable and for this family, it was because it was a new home construction. They battled on trying the get the builder to fix the problems. This case study deep dives into something called building-related illness and explores its relationship with sick building syndrome.
The paper is important because it includes an evaluation of the home from an Occupational Hygiene viewpoint as well as the Environmental Medicine perspective. This case study highlights many of the building-specific factors that contributed to water damage and mould as well as the complaint pattern and medical symptoms that were experienced by the children, the mother and the father.
The outcome of this case study revealed that until the family changed their place of residence unwanted health complaints persisted. But once they left the father's health symptoms improved after two weeks. The three children took six months to recover and the mother's symptoms went away after 18 months.
This paper highlights that long term exposure to mould was the cause of building-related illness. Use this paper to support your position especially if you're ever needing to prove the health hazards from mould inside buildings

I'm often asked whether mould affects children's health? I thought this would be an appropriate topic to kick off the new year for The Mould Show in 2022. In approaching this topic, I'm going to review some of the key symptoms associated with exposure to mould and then provide you with an easy visual guide that you can use to not only remember the typical mould symptoms but the causes and effects but that may be helpful when describing indoor air quality issues in your home or workplace.
We all know that unexpected weather increasingly contributes to mould problems indoors in addition to water leaks and home dilapidation problems. In turn, most of us understand that moulds grow on wet surfaces and release their spores into the air. Itâs important to remember that mycotoxin levels inside water-damaged buildings are sometimes 1000-fold higher than the mould count. It's also known that 50% of fungal growth can be hidden and is missed by mould testing according to the EPA.

When you think about the over 5M fungal species that exist on the planet and juxtapose this against the approximate 2000 mushrooms species we might eat as food - there really are a lot of chance and probable possibilities for us to come into contact with these microorganisms in our everyday lives.
This new paper that came out from the Lawrence Berkeley National Laboratory is quite an eye-opener because it looked at how fungal communities inside 1135 homes in the United States is connected with something called the Infection Fatality Ratio (IFR) which describes the number of deaths caused by COVID-19 per 1000 coronavirus infections.
Their research showed that an increased fungal diversity especially for specific Species of indoor fungi versus outdoor fungi (Beta diversity) was associated with a reduced infection fatality ratio.
In their paper, they looked at whether there was a correlation between certain Species of fungi and adverse outcomes from COVID? And amazingly they found that âyesâ there is!
They found that something called the beta diversity assessed from a comparison between fungal spore types collected outdoors and then inside the home living environment was of fundamental importance.
The key result is that: high diversity of outdoor fungi when also present indoors is associated with a suppression effect for COVID-19 mortality.
This means that collecting spore trap measurements from the outdoors and indoors is very important for predicting adverse events like mortality from COVID-19 and emphasizes the importance of the environment on human illness. Now itâs not just the raw numbers of fungi, but the overlap of which types are present outdoors and also found indoors which defines different aspects of Species richness and diversity.
The research showed that at least four of the following seven fungal genera have a key role in suppressing coronavirus infections. These were: Alternaria, Aspergillus, Epicoccum, Eurotium, Toxicocladosporium and Wallemia as well as a novel Mycosphaerellaceae fungus.
You could argue that simply airing out your property will naturally bring fresh outdoor air containing mould spores indoors. So, wouldnât that automatically select for the correct beta diversity ratio thatâs better for your health?
On the surface, you'd be right to conclude this. However, I've personally done 1000s of indoor air quality inspections over the years and many homes have hidden mould problems that contribute to poor indoor air quality. This is often caused by water damage and dampness and in most of these cases, there is a skewed distribution of fungi indoors thatâs very different to the outdoors.
This publication is extremely important because it shows a correlation effect between bioaerosol counts especially mould spores and respiratory disease outcomes. The key takeaway here is that COVID-19 mortality is suppressed inside homes where the outdoor fungi occur indoors at very similar levels.
When the skewness or difference between the outdoor: indoor diversity changes, or when the indoor fungi are significantly different to the outdoors, then COVID-19 mortality increases.
These researchers found that fungal beta diversity was a much stronger correlate for adverse COVID-19 outcome as age. For example, older persons have worse COVID-19 outcomes, and this paper says that fungal beta diversity in the wrong direction is also bad for your health. The authors stress the method is unlikely to be restricted only to coronavirus but could extend to surveillance of other allergic and viral diseases. This research, therefore, underscores the importance of fungal biosurveillance in the built environment to improve public health outcomes.

This week on The Mould Show, I'm going to be talking about censorship of mould illness. And to do this, weâll be reviewing a paper that came out earlier this year that focused on the situation in Finland. Essentially, this is a battle between free democracy and socialism and the impact that politics has on contemporary scientific thinking and the dissemination of applied science into the wider community.
So, what's this all about? Well, most of us understand the connection between bad indoor air quality and water damage and how this can impact our health. However, I'm always amazed when people try to negate this connection between environmental exposure and illness or outright deny the scientific facts.
This is very perplexing because on the one hand, when the mainstream media is considering carbon credits, or net-zero, they seem to have no trouble linking the slightest change in the environment with some type of consequence to someone somewhere.
In certain socialist, corporatist European countries like Finland, mould related illness has become highly politicized. And today we're going to be reviewing a paper put out by Professor Tamara Tuuminen in May/June 2021. She is a very courageous scientist and doctor who discusses the fact that even though the epidemiological literature shows an overwhelming consensus that mould induces a multi-organ symptomology way beyond just the sniffles - that many government and corporate institutions in her country of Finland deny this link.
She discusses the Government Department of Health and Welfare as well as the Finnish Institute of Occupational Health as two of the key institutions that aim to deny mould as a real environmental illness. Her paper discusses how this is achieved using corporatist special interest groups and educational bodies who often position themselves as independent opinion leaders. In many cases, they are far from unbiased and can demonstrate corruption by not disclosing hidden conflicts of interest or selectively quoting only those academic works of literature that support the government or corporate agenda.
In the Livestream, I'm going to present evidence as far back as 1964 showing that this approach is patently false, and any non-brainwashed person can easily verify these facts for themselves. DYOR and it quite easy then to connect environmental illnesses connected with mould and the many very real physiological problems that can ensue.
I'll also discuss how the Finnish attempt to use mindfulness exercises and referrals to psychologists or psychiatrists, instead of addressing the fundamental problem of indoor air quality and building damage. Contemporary, mainstream narrative protocols instead blame the person for the sickness and from a clinical perspective, attempt to retrain the patientâs brain to remove the stressful situation.
I hope you'll join with me and watch the live stream or download the podcast which touches on multiple areas of contemporary #FollowTheScience and #Censorship of science and how this has become politicized.
Iâll conclude with some recommendations that you can follow to minimize this bias to get at the ground truth and let the science help rather than hurt you.

In this presentation, I want to review something called salt therapy, which is considered a complementary method for the treatment of respiratory tract illnesses. This will have a special focus on mould related disease. Clinical practice referrals my Company receives revolve around exposure to indoor air dampness and mould, usually in the home. When this is prolonged, it can cause problems including: vocal cords irritation, rhinitis, cough, wheezing and recurrent infections of the upper and lower respiratory tract. Breathing in bioaerosols might also make existing asthma worse or bring on new asthma in children or adults. Many of the client and patient referrals we receive complain that their doctor does not truly understand their symptoms or may even consider some of these to be psychosomatic.
Apart from focussing on fixing the building, what can you do to âget wellâ if youâre mould affected? To this end, an important paper recently came out in the Journal: Alternative Therapies in June 2021. Salt therapy is put forward as a treatment for mould related illness. But what is it and why does it work?
Salt therapy has developed into a holistic complementary therapy available in day spa-like environments based on observations made by a 19th century Polish doctor, Feliks Boczkowski. He noticed that salt mine workers had far fewer skin and respiratory health symptoms compared with other mine workers.
Later during World War II in Germany, people who sheltered during bombing in salt caves were observed to experience relief from respiratory problems. Salt therapy exploits or mimics the microclimate of natural salt caves. People who spend time in these caves are take advantage of what is called Spleotherapy in the literature. This involves inhaling pure sodium chloride, NaCl along with other aerosolized elements including magnesium and calcium. A different version termed Halotherapy allows people to experience the benefits of salt therapy by spending time in a room that has salt coated walls and floor. Halotherapy may also use a generator (termed a halogenerator) to produce fine sodium chloride aerosols (1-5-micron diameter) which are aerosolized in the âsalt roomâ.
The salt easily penetrates into all parts of the respiratory tract and has antibacterial and anti-inflammatory properties. Salt particles also promote ciliary transport in the lung, allowing mucus plugs to be coughed up and it also reduces IgE inflammatory levels.
Doctors have used salt therapy in the treatment of allergic rhinitis, asthma, COPD, bronchitis for cystic fibrosis and for viral bronchiolitis. There is even research support linking the use of salting of face masks to neutralize the SARS-CoV-2 virus in an effort to combat COVID-19.
Salt therapy is known to be 100% natural and it's generally safe because it improves the clearance of particulates from the lung, often provides relief from coughing and reduces bronchial inflammation. Itâs easily experienced by spending time in a salt room (30-60 min. sessions) repeated 10 to 20 times. If your home might be mouldy, then consider salt your new ally for health promotion.

Black fungus disease can have a devastating impact for people who contract COVID 19 and even for those who are recovering from COVID-19 and who are more properly classed as COVID long haulers.
My purpose in presenting this live stream is really to bring about awareness to every person about the potential impact of black fungus and explore some of the reasons why everyone should be aware of post-COVID infection co-infection with black fungi. It is my hope that this live stream prevents unnecessary illness, infection and even death.
So, what are the common types of black fungus and why is this connected with COVID? To answer this question, I need to focus on two of the most common fungi that are implicated in mucormycosis and they are from the Genus that includes Rhizopus sp. and Mucor sp. These are typically fast-growing fungi that produce copious spores.
The problem is that these black coloured fungi in the immunocompromised hosts such as those recovering from COVID can utilize the iron in blood as a food source. It must be remembered that the pre-COVID infectious period includes the one to two weeks prior to symptoms. The next month is the acute phase of COVID infection. And after five weeks, this is the post-COVID-19 period.
Those admitted to hospital are commonly offered steroid medications. These steroids like dexamethasone work by dampening down the body's immune system, but at the same time they also increase the levels of iron in the blood, which the black fungi use as a food source. Although dexamethasone does work and is a relatively inexpensive medication, it is a problem for treatment, especially when this has become widespread due to the fact that although it produces an anti-inflammatory effect, this property is at the same time, immunosuppressive in action. These mean this steroid has two contrasting properties as a treatment.
There are many ways in which black fungus can enter the body. Depending on where it enters, this determines the impact of the severity of the fungal infection.
So, what is the takeaway from this particular livestream? Number one, it's very important that you know whether or not you are at risk. Just because you've recovered from COVID 19 does not mean that your body is capable of neutralizing invading pathogens like the black fungi. Everyone should be mindful of the fact the indoor living environment has an effect on your overall health and predisposition to infection. Therefore, inadequate hygiene, high humidity, and water damaged materials can cause an already compromised immune system to become susceptible to various diseases.

Common health concerns from mould include: asthma, allergic rhinitis, wheeze, cough, shortness of breath, or hypersensitivity pneumonitis, headache, eye and skin problems and other health issues. It is reasonably well known, at least by the integrative health community, that exposure to moulds and other fungi is correlated with a range of allergic and pulmonary diseases in susceptible individuals.
Allergy is often tested using antigen extracts. The paper we're discussing today shows that the available antigen extracts are not well matched to the types of fungi that are commonly found indoors.
Allergic sensitization is measured in vivo by something called the skin prick or intradermal testing method or by serological testing against a panel. Fungal antigens are therefore used to determine reaction and it is an important clinical diagnostic that supports environmental inspections.
It is also known that environmental remediation is correlated with improved outcomes of hypersensitivity pneumonitis and asthma. But linking these conditions with buildings relies on either the environmental inspection or the clinician being able to prove the allergy using fungal antigens.
This important paper shows that the actual spore counts in the air reveal exactly which fungi are most likely to induce allergy.
The research reviewed nearly 25,000 indoor air samples from over 7,500 mould affected or complaint homes and compared them against nearly 30,000 outdoor air samples. It was found that the Penicillium fungus was the dominant Genus in water damaged homes and was more common than Aspergillus.
Overall five important Penicillium Genus fungi and three Aspergillus Genus species were identified as the predominant indoor water damage related fungi. Notably, none of the Penicillium species and only one of the Aspergillus species have a clinical antigen extract available for skin testing or serum testing.
The conclusions show variously that commercial production of additional antigen extracts are required and that air spore count measures are fundamentally important to determine risk level of the indoor air versus the outdoor air.
So, what is healthy air versus unhealthy air? The researchers review the recommendations put forward by the American Industrial Hygiene Association (AIHA) who state that higher indoor versus outdoor mould levels, determined using either viable Petri plate culture or spore trap air sampling should be considered as unhealthy.
This new research also introduces a new quantitative minimum threshold risk level:
Where the combined concentration level of Penicillium/Aspergillus fungi in the indoor air is greater than 200 colony forming units per cubic meter of air (CFU/m3) higher than in the outdoor air. This may be an appropriate evidence-based benchmark.
This research concludes by stating that the accuracy of clinical detection of mould sensitivity can be significantly improved by (1) adding new antigen extracts for the predominant species of Penicillium and Aspergillus commonly identified in damp and mould affected homes and that (2) this will lead to improved outcomes for individuals who suffer from mould related conditions so that (3) timely environmental interventions such as (4) patient relocation and or (5) mould remediation when required can be implemented as a (5) critical component of disease management to improve the outcomes of asthma and hypersensitivity pneumonitis in the built environment.

Summer is approaching, at least for us here in Australia and for some of us, looking down at our toes might bring on a "yuck" reaction. Why are those nails cracked, fragile or showing discoloration? Are you embarrassed by this? What's causing it? How do I stop it? Is this a sign of something worse?
That's the topic of this week's show. And importantly, we're going to be talking about how the health of your toenails and even the health of the nails on your fingers can be used as an indicator of overall health.
To do this, we're going to go through some of the most common questions around nail fungus including symptoms and which groups of people are most likely to get fungal nail infections? What are the terms about this microbial infection and what are the typical fungi that cause this? We'll also talk about some of the environmental hazards for foot fungus as well as how it's diagnosed at the lab and then move on to how you can prevent fungal nail infections and discuss some of the treatments from the research literature. With this foundation we'll then move on to the central topic of today's presentation, which is looking at the association between foot and nail fungus and COVID 19 clinical outcomes and we'll be discussing what the scientists discovered and why it's very important to deal with fungal nail infections because they do have an impact on the clinical outcomes of respiratory illnesses like COVID-19.

Have you ever wondered whether there's a connection between the seasons and flu like epidemics? Well, this week on The Mould Show, we're going to be looking at two recent pieces of evidence, which focus on the fact that current models for flu-like epidemics are not sufficiently explained by the seasonality effect. Now, most of us would think to ourselves that colds and flus are often more frequent in the cooler winter months, and that gives rise to the seasonality effect. However, two papers have recently provided some stunning evidence suggesting that there is a strong statistical association between exposure to pollen and mould and the infection potential of flu-like illnesses.
We know that pollen is allergenic and that it's linked to immune-activation and defence against a range of different respiratory viruses. But, interestingly, it seems to create a bioaerosol that when inhaled, seems to lower the reproduction number of flu-like viruses.
These results for pollen were quickly followed up on by another research group that decided to look at whether or not there was a correlation with mould spore exposure.
And that's the main focus of this live stream. The follow-on paper and results show again, a statistically strong correlation between the total bioaerosol count, the total pollen count, and the total mould spore count and presentations to hospital emergency departments for influenza-like illnesses.
The final part of the presentation will review how the authors have used mould spore counts and pollen counts to show that COVID-19 presentations and hospitalizations are correlated with the airborne mould spores and pollen counts. This data has significant implications for how we understand disease transmission of flu-like illnesses and chosen interventions against. I look forward to you joining me for this exciting episode.

If you've ever found yourself having trouble explaining to someone why you just don't feel right inside that room or building, then you'll want to watch this. Ok, you might just sneeze a little over springtime when exposed to pollen...but what if those types of symptoms happened to you every time you clocked in at work? How do you make sense of this? Sick building syndrome is a catch-all term that is often used to describe the constellation of symptoms that may occur if you react to this "something" indoors. There's also the problem of long-term exposure. If you're constantly exposed to a challenging environment, your symptoms may get worse. That's the topic of the show today and will focus attention on what clinicians know lies beyond sick building syndrome. I'll go over what they know about multiple chemical sensitivity, hypersensitivity and chronic fatigue. The research shows that the duration of exposure along with other co-morbidities leads to a worsening of symptoms and an expansion on the clinical definitions of illness. I conclude with commentary on the important role of site testing and the need for microbiology data. There's a self-serving reason why your insurance-led occupational hygienist or landlord or rogue builder might want to dismiss your claims about health and water damage and mould exposure. There's also a simple argument against such self-serving claims. That's called "Lege artis:" and is Latin for the need to sample the environmental microbiology and toxicology in the same way any other diagnostic specimen is taken. Don't allow any authority to rely on a visual inspection or say that no visible mould was seen and hence there is no problem. Use and be aware of the "Lege artis" and the fact there are multiple Standards and Guidelines for indoor air quality and water damage and microbial assessment. Don't led no data or poor data compromise your health or the lie that mould isnât a problem as long as we dry out your building. Remember thereâs an industry who want your money for works that are all too often poorly implemented or unverified for source removal. If youâve ever been sold the snake oil that âweâll just fog to treat the mouldâ recognize that thatâs not removing the microbial risks and dead mould can still cause a serious immune challenge. This Livestream is for all those that need that one publication to help explain and support how they feel and where the science is at around this topic of risk and exposure to water damage and mould.

Asthma is a common respiratory condition causing an attack or spasm of the bronchioles or airways that carry air to the lungs. Asthma makes it difficult to breathe and in Australia affects one in nine people equivalent to 2.7 million Australians. In the period between 2017-2018 nearly 40,000 hospitalisations occurred. It's known that 80% of asthma hospitalisations are preventable.
Now it's not just the hospital costs - asthma affects quality of life. Asthma sufferers self report their wellbeing as "fair" or "poor" compared with other people without asthma.
Some interesting research was recently published in the journal, Indoor Air in September 2021. It looked at what household features contribute to biocontamination and that are linked with asthma.
What are some of the typical biocontaminants that might cause asthma-type health effects? Most of us can recall images of pollution haze and coughing, but different types of microorganisms, dusts and pollens and household behaviours are also likely suspects.
The paper I'm highlighting is from Canada and the scientists collected dust from people's homes to determine the concentrations of: house dust mite allergens, cat allergens, cockroach allergen, beta-(1,3)-D-glucan and endotoxin levels. They also used a questionnaire as part of home inspections to ask about features and behaviours in the home.
What did they find?
They discovered that the age of the home and whether or not carpets were present along with the history of water damage and mould odour were https://www.rev.com/all positively associated with the presence of multiple indoor contaminants linked to asthma.
They also found that high floor cleaning frequency and the use of dehumidifiers were negatively associated with the presence of multiple indoor contaminants.
This live stream will review this data and list the Top 8 asthma and allergy triggers. I've also created a free survey so you can measure your own home for risk factors linked to asthma and allergic disease. You can find the survey here: https://drcameronjones.checkboxau.com/asthma-and-allergy-triggers

On the 22nd October 2021, Victoria, Australia begins our own Freedom Day. But is this really freedom? State-wide vaccine mandates are in force and there's a need for vaccine passports to enter retail.
For many, significant restrictions remain. The State is still under a form of medical apartheid. Strict coercion around freedom of choice has forced many to choose vaccination just to re-enter society or keep their job.
The censorship around therapeutic options and facts and figures and open debate have largely been silenced across the mainstream media.
This short Livestream discusses a very recent publication that came out (20th October 2021) on the preprint server, medRxiv.
This paper serves as a warning around the very real risks of transmission among the vaccinated.
Please read it for yourself and consider the results and conclusions.

This Week in Victoria and New South Wales and many other parts of Australia we're reopening and a lot of the lockdown restrictions are being lifted. So what does that mean? Well, many of our children will be returning to school - so this week I want to be focusing on a very important non-pharmaceutical intervention, which revolves around indoor air quality. And this is a particularly relevant and topical, because if you've picked up any of the news media over the last couple of weeks, you may have noticed a range of different stories focusing on both the Victorian announcement regarding the $190 million package for air purifiers to be put into all public schools. Similarly, in New South Wales people are calling for stronger ventilation Standards, and this is shining a spotlight on a very important engineering control step to address public health concerns around respiratory viruses. And so today we're going to be focusing on HEPA which stands for High-Efficiency Particulate Air, and I'm going to be reviewing and answering the following questions:
- Are portable air purifiers effective?
- What to look for in an air purifier?
- What are some of the definitions you should be aware of when you look online if you want to purchase one of these HEPA air purifiers for your own home or office?
- Do portable air purifiers work against covid?
- Is there research showing HEPA is of benefit for particulate matter and in turn bacteria, fungi, pollen, and even viruses when they are put to the test?
- What are the best portable air purifiers according to science?
And this should help you out when you return to your High street retailer and look on the box for specifications or DYOR online.
I also want to talk about some of the scientific evidence that is the premise for why HEPA is a valuable intervention. Then, what is the evidence for whether they work or not against the SARS-CoV-2 virus?
I'll also be reviewing some of the writings from expert panels, such as OzSage, and their recommendations regarding carbon dioxide, and ventilation standards for buildings.
Importantly, I will review where HEPA air purifiers fail, and some of the common mistakes that can occur when people are trying to match a portable HEPA air purifier for a particular space.
Finally, I'll round out with some of the benefits that are validated from the literature, such as improving or reducing the probability of hospital-acquired infections, specifically around fungal pathogens.
Then, I'll conclude with some very recent research looking at the benefits of HEPA air quality and depression.

According to the World Health Organization, cardiovascular disease is the leading cause of death globally. In 2019, it was estimated that 17.9 million people died from cardiovascular disease. This represents 32% of all global deaths with 85% being caused by heart attack and stroke. It is further reported that 75% of cardiovascular disease deaths, take place in low and middle-income countries.
Heart disease and mortality is considered a premature death. This is because most cardiovascular diseases can be prevented by focusing on behavioral risk factors. These include tobacco use, unhealthy diet, obesity, a lack of physical activity, and harmful use of alcohol.
It's therefore important to detect cardiovascular disease, as early as possible so it can be managed with lifestyle, counseling and medication as required.
So what can Danish nurses tell us about the risk of heart failure? A lot, actually. A recent paper published in the Journal of the American Heart Association has conducted original research and made some profound discoveries that all of us should be aware of.
So what exactly do I mean when I talk about the Danish nurses in Denmark? A study was begun in the early 1990s, which was looking at 22,189 Danish nurses to determine whether or not there were environmental risk factors connected with heart failure.
The study goals were premised on the fact that millions of people die from heart failure, and those that live are frequently hospitalized, have a poor quality of life, and experience multiple comorbidities.
The researchers already knew that risks like smoking, excess alcohol consumption and obesity were linked to pre-existing conditions like hypertension, coronary artery disease, diabetes, and myocardial infarction. They also knew that air pollution is a recognized risk factor for cardiovascular disease.
Scientists define heart failure, by the reduced ability of the heart to pump or fill with blood. This is a subcategory of cardiovascular disease. The question they were looking at was whether air pollution might induce oxidative stress and inflammation and in turn, cause an imbalance to the autonomic nervous system.
The trial tracked a large number of female Danish nurses, from 1993 and 1999 which was the baseline, all the way up until the end of 2014. Over this nearly 2 decade period, they found some fascinating associations between heart failure and exposure to environmental pollutants.
The key takeaway from the data is that heart failure was strongest when the nurses were exposed to very fine particulate matter (PM2.5) having a diameter of less than 2.5 microns. The researchers also found that road traffic noise was also associated with the incidence of heart failure.
Over 2% of the nurses suffered heart failure. These nurses were most likely to have been exposed to PM2.5, traffic noise, and NO2 pollution. The heart failure nurses were also more likely to be former smokers and to have high blood pressure.
You don't have to be a Danish nurse to recognize that the clinical implications of this research are that air pollution and road traffic noise are correlated with an increased risk of heart failure. Targetting public health interventions to former smokers or those with high blood pressure, as well as those who live with exposure to air pollution is warranted. All of us should be aware of the silent risks to heart health from fine particle air pollution and road traffic noise.
