Wastewater management in Canadian Arctic communities is influenced by several geographical factors including climate, remoteness, population size, and local food-harvesting practices. Most communities use trucked collection services and basic treatment systems, which are capable of only low-level pathogen removal. These systems are typically reliant solely on natural environmental processes for treatment and make use of existing lagoons, wetlands, and bays. They are operated in a manner such that partially treated wastewater still containing potentially hazardous microorganisms is released into the terrestrial and aquatic environment at random times...

Human infections with foodborne pathogenic organisms are relatively well described in terms of their overt physical symptoms, such as diarrhea, abdominal cramps, vomiting, fever, and associated sequelae. Indeed, some of these are key for diagnosis and treatment, although it should be noted that, for some foodborne pathogens, the physical symptoms might be more diffuse, particularly those associated with some of the foodborne parasites. In contrast, the impact of these pathogens on mental health is less well described, and symptoms such as depression, anxiety, and general malaise are usually ignored when foodborne infections are recorded...

The number of restaurants serving sushi within Minnesota is continuously increasing. The practices and protocols of serving raw fish are complex and require detailed planning to ensure that food served to patrons will not cause illness. Although the popularity of sushi is increasing, there is a lack of research on food safety issues pertaining to preparation of raw fish and sushi rice. To address this gap, the Minnesota Department of Health Environmental Health Specialists Network Food program collected descriptive data on restaurant practices and policies concerning the service of raw fish and sushi rice in 40 Minnesota restaurants...

Christopher E Ekpenyong, Asuquo E Asuquo
The impact of health and environmental hazards, associated with the constituents of gasoline, on occupationally exposed workers has been recorded over the past few decades. However, the scientific literature on their pathogenic potential remains incomplete, which could affect the current understanding of the associated health risks. This review provides current information based on recently improved research techniques to evaluate gasoline toxicity profiles for humans. Our current knowledge provides insight into the intricate mechanism of gasoline-induced adverse effects, including the formation of reactive metabolites via bio-activation and subsequent generation of reactive oxygen species (ROS) and oxidative stress, which are involved in multiple mechanisms that are central to the aetiology of gasoline-induced toxicity...

Emerging and reemerging infections have become prevalent in the United States since the 1970s, causing illness, death, and fear among the public. The published literature was reviewed to offer a perspective on risk factors for disease acquisition and to allow a prediction of the next microbial assault after Ebola and Zika. Four well-integrated factors likely will contribute simultaneously: animals colonized or infected by pathogens capable of human transmission, microbes recurrently changing their virulence, a growing number of susceptible people, and climatic and environmental factors encouraging disease transmission...

What gets measured gets managed. Funding of health services is substantially determined by operational activity and specific outcome indicators. In day-to-day clinical decision-making, surrogate markers, such as glycosylated haemoglobin and blood pressure, are commonly used to modify risks of 'hard' outcomes that include kidney failure, ischaemic cardiac events, stroke and all-cause mortality. In many settings, surrogates are all we have to go on. As a consequence, current health funding models heavily rely on surrogate-based key performance indicators [KPIs]...

Reentry interventions for persons with mental illness leaving prison have consisted primarily of linkage to mental health services and have produced mixed results on psychiatric and criminal recidivism. These interventions primarily focus on intra-individual risk factors. However, social and environmental factors may also increase risk of reincarceration by constraining choices and pro-social opportunities for community reintegration upon release from prison. In order to add to the knowledge base on understanding reincarceration risk for men with mental illnesses leaving prison, we examined interpersonal and environmental factors that exposed men to heightened risk for reincarceration...

The Flint Water Crisis-due to changes of water source and treatment procedures-has revealed many unsolved social, environmental, and public health problems for US drinking water, including opportunistic premise plumbing pathogens (OPPP). The true health impact of OPPP, especially in vulnerable populations such as the elderly, is largely unknown. We explored 10(8) claims in the largest US national uniformly collected data repository to determine rates and costs of OPPP-related hospitalizations. In 1991-2006, 617,291 cases of three selected OPPP infections resulted in the elderly alone of $0...

Childhood asthma develops from a complex interaction among host and environmental factors in early life. Birth cohort studies have provided valuable insight into asthma risk factors and the natural history of wheezing and asthma through childhood and beyond. Early life aeroallergen sensitization and wheezing illnesses associated with virus and bacterial infections have been identified as pivotal risk factors for asthma inception. Recently, focus has turned toward protective factors that promote lung health in children...

Underserved communities suffer from environmental inequities. Gases lead to hypoxia and respiratory compromise, ozone to increased respiratory illnesses and decreased mental acuity, and mercury to prenatal cognitive disabilities and antisocial behaviors. Lead toxicity is associated with developmental delays. Cadmium is linked with cancer. The smaller sizes of air pollution particulate matter are pathogenic and are associated with cardiovascular and pulmonary disease and nervous system disorders. Bisphenol A is being studied for possible links to cancer and pregnancy risks...

: Detecting human wastewater contamination in recreational waters is of critical importance to regulators due to the risks posed to public health. To identify such risks, human wastewater associated microbial source tracking (MST) markers have been developed. At present, however, greater understanding of the suitability of these markers for the detection of diluted human wastewater in environmental waters is necessary to predict risk. Here, we compared the process limit of detection (PLOD) and quantification (PLOQ) of six human wastewater associated MST markers [Bacteroides HF183 (HF183), E...

: Legionella pneumophila cause waterborne infections resulting in severe pneumonia. High resolution genotyping of L. pneumophila isolates can be achieved by Multiple-Locus Variable number of tandem repeat Analysis (MLVA). Recently, we found that different MLVA genotypes of L. pneumophila, dominated different sites in a small drinking-water network, with a genotype-related temperature and abundance regime. The current study focuses on understanding the temperature-dependent growth kinetics of the genotypes that dominated the water network...

PURPOSE OF REVIEW: Campylobacter jejuni is recognized as one of the most common causes of food-borne gastrointestinal illness worldwide, resulting in a self-limiting dysentery in developed countries. However, it is increasingly gaining attention due to its association with postinfectious complications such as Guillain-Barré Syndrome and recently recognized importance in early childhood diarrhea in developing countries. We hypothesize that the inflammation mediated by C. jejuni infection causes environmental enteric dysfunction, and with contribution from diet and the host, microbiome may be responsible for growth faltering in children and developmental disability...
