Health effects of trans fatty acids (TFAs) on human organisms can vary according to their type, structure, composition, and origin. Even though the adverse health effects of industrial TFAs (iTFAs) have been widely discussed, the health effects of natural TFAs (nTFAs) are still questionable. Hence, it is important to review the literature and provide an overall picture on the health effects of different TFAs coming from industrial and ruminant sources, underlining those types that have adverse health effects as well as suggesting methods for reducing their harmful effects. Multiple databases (PubMed, Medline, Cochrane Library, etc.) were searched with the key words “trans fatty acid sources”, “ruminant”, “industrial”, “conjugated trans linoleic acid”, “human”, “coronary heart disease”, “cancer”, etc. Reference lists of the studies were scanned discussing the health effects of iTFAs and nTFAs. The review of the literature showed that iTFAs are found to be more harmful than ruminant-produced nTFAs. Although several beneficial effects (such as reduced risk of diabetes) for nTFAs have been observed, they should be used with caution. Since during labeling it is usually not mentioned whether the TFAs contained in food are of industrial or natural origin, the general suggestion is to reduce their consumption.

Objectives: To describe the acute health impacts of the Deepwater Horizon oil spill in Louisiana as compared with the acute health impacts reported from prior crude oil spills. To predict potential chronic health impacts in Louisiana as compared with the chronic health impacts reported from prior crude oil spills.Setting: Offshore and onshore coastal southeastern Louisiana.Patients and participants: Oil spill offshore and onshore cleanup workers and the general population of coastal southeastern Louisiana.Interventions: Not applicable to an observational study.Main outcome measures: Adverse acute health effects of petrochemical and dispersant exposures in highly exposed offshore and onshore cleanup workers and the general population; prior chronic adverse health effects reported from prior oil spills; and predicted chronic adverse health effects based on intensity of chemical exposures and on seroprevalences of genetic polymorphisms.Results: Acute health effects in cleanup workers mirrored those reported in cleanup workers following prior oil spills as ranked by systems (and by symptoms). Acute health effects in lesser exposed members of the general population mirrored those reported in similar coastal residents following prior oil spills but differed from cleanup workers as ranked by systems (and symptoms).Conclusions: Subpopulations of cleanup workers and the general population with specific conditions or genetic polymorphisms in enzyme systems that detoxify polycyclic aromatic hydrocarbons in petrochemicals and glycols in dispersants will require long-term surveillance for chronic adverse health effects including cancer, liver and kidney diseases, mental health disorders, and fetal alcohol spectrum disorders.

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).

Perception Action

It is usually a mark of good design when technologies and tools that mediate goal-directed action are such that the user’s attentional focus is maintained on the intended ends of action rather than on the technologies and tools themselves. When the mediators become the focus, the continuity of goal-directed action is disrupted, and the flow of action can be re-directed. What then is the purpose of the projects designed by the RAAAF studio, as described by Rietveld, which seem to be intended to do both? Disruption of the continuity of goal-directed perception-action may prompt reflection about the circumstances at work, and in so doing provoke a transformation in habitual patterns of action and of thought. The project “The End of Sitting” is intended to remediate the adverse health effects of standard chair-dominated offices through an unconventional office landscape that prompts intermittent postural readjustments, boosting the levels of activity common in such settings. The project “Bunker 599” demonstrates that seemingly unremarkable features of the landscape can sometimes conceal aspects of culture’s history, and that design can function to draw attention to a hidden and even vanishing history. Design can enrich an individual’s sense of place in a stream of cultural history.

The Impact

Worldwide, several million workers are employed in the various chromium (Cr) industries. These workers may suffer from a variety of adverse health effects produced by dusts, mists and fumes containing Cr in the hexavalent oxidation state, Cr(VI). Of major importance, occupational exposure to Cr(VI) compounds has been firmly associated with the development of lung cancer. Counterintuitively, Cr(VI) is mostly unreactive towards most biomolecules, including nucleic acids. However, its intracellular reduction produces several species that react extensively with biomolecules. The diversity and chemical versatility of these species add great complexity to the study of the molecular mechanisms underlying Cr(VI) toxicity and carcinogenicity. As a consequence, these mechanisms are still poorly understood, in spite of intensive research efforts. Here, we discuss the impact of Cr(VI) on the stress response—an intricate cellular system against proteotoxic stress which is increasingly viewed as playing a critical role in carcinogenesis. This discussion is preceded by information regarding applications, chemical properties and adverse health effects of Cr(VI). A summary of our current understanding of cancer initiation, promotion and progression is also provided, followed by a brief description of the stress response and its links to cancer and by an overview of potential molecular mechanisms of Cr(VI) carcinogenicity.
