BACKGROUND: While children's exposure to environmental lead in the U.S. has decreased, areas of elevated levels remain. Because lead exposure is a risk factor for developmental delays, it should be considered when studying neurodevelopmental effects of in-utero antiretroviral medication (ARV) exposure in the growing population of perinatally HIV-exposed, uninfected children (PHEU). We compared blood lead levels (BPb) in PHEU children enrolled in the Surveillance Monitoring of ART Toxicities (SMARTT) Study to U...

Rodent health-monitoring programs based on sampling an IVC system's exhaust air dust (EAD) has enhanced and even replaced traditional sentinels for some rodent pathogens. EAD testing by qPCR assay is an optimal surveillance method for the rapid detection of Corynebacterium bovis-infected immunodeficient mice. Here we demonstrate that an active EAD surveillance program for C. bovis can be used to maintain nude mice C. bovis-free after the transition from historically enzootically infected colonies. During 3 events over 3 y, rapid detection of infection, elimination of infected mice, aggressive quarantine measures, and local decontamination prevented the spread of C...

There has been limited research studying neighbourhood support for caregivers. Therefore, the aim of the present study was to investigate the support from neighbourhoods between both caregivers and non-caregivers in a country-wide and population-based setting. Data were retrieved from England Community Life Survey, 2012-2014, a new annual household survey conducted by face-to-face interview since 2012, with a representative sample size of 5-6000 adult (aged 16 years and over) resident per year in England. Chi-square test and logistic regression modelling were performed to examine the variance in support from and perception toward neighbourhoods between caregivers and non-caregivers...

INTRODUCTION: Better knowledge of the factors that have an impact on pathways to mental health care may contribute greatly to organizing optimum health-care delivery. However, surveillance systems concerning alcohol problems in the French general population are suboptimal. The objectives of this study were to investigate: 1) the prevalence of mental health-care seeking in individuals with alcohol abuse/dependence in France, 2) which category of medical practitioner was consulted, and 3) psychological and socio-environmental factors associated with mental health-care seeking...

OBJECTIVE: Oral cancer (OC) is a leading cause of death from cancer in men between the ages of 25 and 44 years in Taiwan. The overall 5-year survival rates for the four OC stages (I-IV) in Taiwan are approximately 70%, 30%, 20%, and 10%, respectively, indicating the importance of the early diagnosis of oral potentially malignant disorders (OPMDs). Previous studies indicated an association between the OC incidence and certain environmental heavy metal concentrations. If these associations do exist for OC, they may also be observed for OPMD...

REVIEW
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...

BACKGROUND: Ethiopia has the second largest human population in Africa and the largest livestock population on the continent. About 80% of Ethiopians are dependent on agriculture and have direct contact with livestock or other domestic animals. As a result, the country is vulnerable to the spread of zoonotic diseases. As the first step of the country's engagement in the Global Health Security Agenda, a zoonotic disease prioritization workshop was held to identify significant zoonotic diseases of mutual concern for animal and human health agencies...
