Economic Significance

Fusarium species produce toxic mycotoxins that are known to exert adverse health effects in humans and animals. No attempts have been made to establish mycotoxin-producing capabilities of isolates of Fusarium species from bananas exhibiting symptoms of crown rot. Crown rot is one of the most serious post harvest problems in banana and the disease is caused by different fungal species, principally Fusarium species. Banana, which is of great economic significance in growing countries (i.e. Costa Rica, Cameroon, Ecuador) is seriously affected by crown rot and is a major cause of fruit loss

Concentrations of outdoor air pollution are on the rise, particularly due to rapid urbanization worldwide. Alternatively, poor ventilation, cigarette smoke, and other toxic chemicals contribute to rising concentrations of indoor air pollution. The World Health Organization recently reported that deaths attributable to indoor and outdoor air pollutant exposure are more than double what was originally documented. Epidemiological, clinical, and animal data have demonstrated a clear connection between rising concentrations of air pollution (both indoor and outdoor) and a host of adverse health effects. During the past five years, animal, clinical, and epidemiological studies have explored the adverse health effects associated with exposure to both indoor and outdoor air pollutants throughout the various stages of life. This review provides a summary of the detrimental effects of air pollution through examination of current animal, clinical, and epidemiological studies and exposure during three different periods: maternal (in utero), early life, and adulthood. Additionally, we recommend future lines of research while suggesting conceivable strategies to curb exposure to indoor and outdoor air pollutants.

Mycotic Infections

Mycotic keratitis has been found to account for 6% to 50% of all cases of ulcerated keratitis. Fusarium species, and in particular Fusarium so/ani, is the most frequent cause of mycotic infections of the cornea. These infections lead to a marked loss of vision and eventually a complete perforation of the cornea if not correctly diagnosed and treated. Fusarium species produce toxic mycotoxins that are known to exert adverse health effects in humans and animals. However, very few attempts have been made to establish the mycotoxin-producing capabilities of clinical isolates of Fusarium species from keratitis infections or any other human infections for that matter.

The Ideal

Indoor swimming pools are the ideal environment for mold growth as they are intentionally humid and warm. Although there are no established safe exposure levels for airborne mold spores, their presence has been associated with adverse health effects that may put individuals at risk. The objective of this pilot study was to observe the occurrence of airborne mold within indoor swimming pools (n = 6) in the Greater Toronto Area. Viable air samples were taken using a Surface Air System air sampler and cultured to quantify and identify airborne mold using microscopy. In addition, relative humidity and temperature were measured and facility characteristics were recorded. Overall, the mold counts were relatively low and were consistent with the literature. However, a biodiverse fungal profile was found at most sites—some of which included fungal groups linked to harmful health effects in humans. Since this was a pilot study, further research is suggested to determine whether the concentration of mold is a cause for concern.

IntroductionPerfluoroalkyl and polyfluoroalkyl substances (PFAS) are a diverse group of compounds that have been used in hundreds of industrial applications and consumer products including aqueous film-forming foam (AFFF) for many years. Multiple national and international health and environmental agencies have accepted that PFAS exposures are associated with numerous adverse health effects. Australian firefighters have been shown to have elevated levels of PFAS in their blood, specifically perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS), due to the historical use of AFFF. While PFAS concentrations decline over time once the source of exposure has been removed, their potential adverse health effects are such that it would be prudent to develop an intervention to lower levels at a faster rate than occurs via natural elimination rates.Methods and analysisThis is a randomised controlled trial of current and former Australian firefighters in the Metropolitan Fire Brigade/Fire Rescue Victoria, and contractors, with previous occupational exposure to PFAS and baseline elevated PFOS levels. The study is investigating whether whole blood donation every 12 weeks or plasma donation every 6 weeks will significantly reduce PFAS levels, compared with a control group. We have used covariate-adaptive randomisation to balance participants’ sex and blood PFAS levels between the three groups and would consider a 25% reduction in serum PFOS and PFHxS levels to be potentially clinically significant after 12 months of whole blood or plasma donation. A secondary analysis of health biomarkers is being made of changes between screening and week 52 in all three groups.Ethics and disseminationThis trial has been approved by Macquarie University Human Research Ethics Committee (reference number: 3855), final protocol V.2 dated 12 June 2019. Study results will be disseminated via peer-reviewed publications and presentations at conferences.Trial registration numberAustralian New Zealand Clinical Trials Registry (ACTRN12619000204145).
