- Artisanal fisheries generally do not have injury prevention plans and safety or quality management systems on board, thus making them prone to more fatal and nonfatal injuries. The objective of the study is to systematically review and synthesize the literature to identify the risks of injuries (fatal and nonfatal) and health problems in artisanal fisheries in developing countries.
- A globally effective vaccine strategy must cope with the broad genetic diversity of HIV and contend with multiple transmission modalities. Understanding correlates of protection and the role of diversity in limiting protective vaccines with those correlates is key. RV144 was the first HIV-1 vaccine trial to demonstrate efficacy against HIV-1 infection. A correlates analysis comparing vaccine-induced immune responses in vaccinated-infected and vaccinated-uninfected volunteers suggested that IgG specific for the V1V2 region of gp120 was associated with reduced risk of HIV-1 infection and that plasma Env IgA was directly correlated with infection risk.
- Dengue is a rapidly expanding global health problem. Development of a safe and efficacious tetravalent vaccine along with strategic application of vector control activities represents a promising approach to reducing the global disease burden. Although many vaccine development challenges exist, numerous candidates are in clinical development and one has been tested in three clinical endpoint studies. The results of these studies have raised numerous questions about how we measure vaccine immunogenicity and how these readouts are associated with clinical outcomes in vaccine recipients who experience natural infection.
- Major vaccine safety controversies have arisen in several countries beginning in the last decades of 20th century. Such periodic vaccine safety controversies are unlikely to go away in the near future as more national immunization programs mature with near elimination of target vaccine-preventable diseases that result in relative greater prominence of adverse events following immunizations, both true reactions and temporally coincidental events. There are several ways in which vaccine safety capacity can be improved to potentially mitigate the impact of future vaccine safety controversies.
- In 2013 there were an estimated 584,000 deaths and 198 million clinical illnesses due to malaria, the majority in sub-Saharan Africa. Vaccines would be the ideal addition to the existing armamentarium of anti-malaria tools. However, malaria is caused by parasites, and parasites are much more complex in terms of their biology than the viruses and bacteria for which we have vaccines, passing through multiple stages of development in the human host, each stage expressing hundreds of unique antigens.
- Opportunities for global health training during residency are steadily increasing. For example, surveys show that more than half of residency programs now offer international electives. Residency programs are increasingly recognizing that global health training improves communication skills, fosters awareness of health disparities, and inspires careers in primary care and public health. Although research has focused on global health education in other specialties, there is a paucity of research on global health training in public health and general preventive medicine (GPM).
- Although childhood deaths from communicable diseases have declined during the last decade, the proportion of deaths resulting from injuries has increased steadily during the same period across the world.1 Drowning is the second leading cause of injury-related deaths among children worldwide. It accounted for approximately 359,000 deaths in 2011, of which 18% occurred in children between the ages of 1 and 4 years.2 Thirty-seven percent of the drowning deaths in this age range occur in South Asia region alone,3 comprising six countries, including Afghanistan, Bangladesh, Bhutan, India, Nepal, and Pakistan.
- Systematic reviews of public health interventions are useful for identifying effective strategies for informing policy and practice. The goals of this review were to (1) update a previous systematic review of physical activity interventions in Latin America which found that only school-based physical education had sufficient evidence to recommend widespread adoption; (2) assess the reporting of external validity elements; and (3) develop and apply an evidence typology for classifying interventions.
- Recent large-scale clinical trials in the U.S., Latin America, Africa, and Asia have demonstrated the effectiveness of pre-exposure prophylaxis (PrEP), which is the use of HIV treatment medications to protect uninfected individuals from HIV infection. Incorporating PrEP into existing HIV prevention programs, however, poses a number of challenges. In the U.S., those programs that are most likely to be cost effective may nevertheless fail to achieve one of the most important objectives of public health: improving the health of the community while addressing the needs of the most disadvantaged.
