OBJECTIVE: In a study to identify exposures associated with 15 cases of childhood leukemia, we found levels of tungsten, arsenic, and dichlorodiphenyldichloroethylene in participants to be higher than mean values [...]

BACKGROUND. Sixteen children diagnosed with acute leukemia between 1997 and 2002 lived in Churchill County, Nevada, at the time of or before their illness. Considering the county population and statewide [...]

Objectives. Although banned nationwide for waterfowl hunting, lead shot is still used for hunting in regions of Alaska. Consumption of birds hunted with lead shot may be a route of human lead exposure in susceptible populations. The Centers for Disease Control and Prevention (CDC) and Alaskan health officials conducted a cross-sectional exposure assessment and used isotope ratios (IR) to test that assumption. Study Design. Cross-sectional exposure assessment study. Methods. We compared isotopic profiles of blood lead in Alaska Native women from Bethel (n=10) and Barrow (n=10) to lead shot samples purchased from the respective regions. To evaluate the source of lead for the buckshot, we evaluated IR profiles for lead mineral and ore from a smelter in Torreon, Mexico, a suspected source of origin for the lead. Results. The lead IRs for the blood lead differed significantly from the lead shot IRs (p< 0.001); thus, lead shot is unlikely to be the sole source of lead exposure of public health significance in participants of this study. Overlap in IRs for the lead shot and blood lead existed for 6 (30%) of the women from Bethel and Barrow; however, no correlation was noted between lead levels and the IRs for the blood lead. IR profiles for lead mineral and ore from Mexico were substantially different from the IRs of lead shot from Alaska, confirming that buckshot in this study is unlikely to originate from the Mexican smelter. Conclusions. Lead shot from the manufacturer in this study does not appear to be the sole source of lead exposure in most participants; nonetheless, lead shot could yet be a potential source of exposure in some populations, possibly those whose diet consists of game hunted with lead shot.

OBJECTIVE To review publications that address female reproductive health hazards in veterinary practice, summarize best practices to mitigate reproductive risks, and identify current knowledge gaps. DESIGN Systematized review. SAMPLE English-language articles describing chemical, biological, and physical hazards present in the veterinary workplace and associations with adverse reproductive outcomes or recommendations for minimizing risks to female reproductive health. PROCEDURES Searches of the CAB abstracts database were performed in July 2012 and in May 2015 with the following search terms: veterinarians AND occupational hazards and vets.id AND occupational hazards.sh. Searches of the PubMed database were conducted in November 2012 and in May 2015 with the following medical subject heading terms: occupational exposure AND veterinarians; anesthetics, inhalation/adverse effects AND veterinarians; risk factors AND pregnancy AND veterinarians; pregnancy outcome AND veterinarians; and animal technicians AND occupational exposure. Two additional PubMed searches were completed in January 2016 with the terms disinfectants/toxicity AND female AND fertility/drug effects and veterinarians/psychology AND stress, psychological. No date limits were applied to searches. RESULTS 4 sources supporting demographic trends in veterinary medicine and 118 resources reporting potential hazards to female reproductive health were identified. Reported hazards included exposure to anesthetic gases, radiation, antineoplastic drugs, and reproductive hormones; physically demanding work; prolonged standing; and zoonoses. CONCLUSIONS AND CLINICAL RELEVANCE Demographic information suggested that an increasing number of women of reproductive age will be exposed to chemical, biological, and physical hazards in veterinary practice. Information on reproductive health hazards and minimizing risk, with emphasis on developing a safety-focused work culture for all personnel, should be discussed starting in veterinary and veterinary technical schools and integrated into employee training.

Although the interconnection of humans, animals, and ecosystems has been recognized historically, increasing specialization of professionals in the twentieth century led to decreased communication and collaboration among sectors. In early 2000, a One Health vision of global interconnectedness began gaining in popularity and a series of meetings were held extolling the One Health vision. However, by 2009, detractors were claiming that the One Health approach was indeed all vision and no action. In response to this, international organizations sponsored a carefully planned and structured meeting to construct a way forward that would lead to tangible outcomes. The Stone Mountain meeting, Operationalizing "One Health": A Policy Perspective-Taking Stock and Shaping an Implementation Roadmap led to the formation of seven multi-national work groups with defined timelines and outputs. The process has garnered increasing participation and support, and the work groups are on track to demonstrate the value added of a One Health approach.
