Nearly 25% of the global population (1.8 billion people in 2012) is consuming fecally-contaminated water. This water can contain bacteria, protozoa, and viruses that can cause a variety of diseases in humans, most notably gastroenteritis. The impact on public health is staggering. Unsafe water, inadequate sanitation, and poor hygiene are responsible for about 90% of diarrheal deaths worldwide. Not surprisingly, diarrhea is the second leading cause of death for children under the age of five globally (1.2 million deaths in 2012).

Surface weather conditions are closely governed by the large-scale circulation of the Earth’s atmosphere. Recent increases in the occurrence of some extreme weather phenomena have led to multiple mechanistic hypotheses linking changes in atmospheric circulation to increasing probability of extreme events. However, observed evidence of long-term change in atmospheric circulation remains inconclusive.

Antarctic biodiversity is much more extensive, ecologically diverse and biogeographically structured than previously thought. Understanding of how this diversity is distributed in marine and terrestrial systems, the mechanisms underlying its spatial variation, and the significance of the microbiota is growing rapidly.

In May 2015, the 21st Century Cures Act was introduced in the U.S. House of Representatives, with the goal of promoting the development and speeding the approval of new drugs and devices.1 Championed by the pharmaceutical, biotechnology, and device industries, the bill was approved unanimously (51 to 0) in committee and continues to be debated. If enacted into law, some of its provisions could have a profound effect on what is known about the safety and efficacy of medical products, as well as which ones become available for use.

Many observers were surprised when Indiana Governor Mike Pence issued an executive order on March 26, 2015, declaring a public health emergency after a rapidly escalating outbreak of human immunodeficiency virus (HIV) was identified in Scott County, a rural region on the Kentucky border. Others, however, had seen it coming. (Perspective)

The researchers assessed high cholesterol (HC) awareness, treatment, and control rates among US Hispanic/Latino adults and describe factors associated with HC awareness and management.

The ongoing west Africa Ebola-virus-disease epidemic has disrupted the entire health-care system in affected countries. Because of the overlap of symptoms of Ebola virus disease and malaria, the care delivery of malaria is particularly sensitive to the indirect effects of the current Ebola-virus-disease epidemic. We therefore characterise malaria case management in the context of the Ebola-virus-disease epidemic and document the effect of the Ebola-virus-disease epidemic on malaria case management.

According to this research published in the journal The Lancet, climate change poses a potentially “catastrophic risk” to public health due to increased risk of the spread of disease, food insecurity and air pollution among many other things. 

Pentaalkylcyclopentadienyl (Cp*R) iridium (Ir) and cobalt (Co) 1,2-diamine complexes were synthesized. Susceptibility of Staphylococcus aureus and recent patient methicillin-resistant S. aureus (MRSA) isolates to the transition metal–diamine complexes were measured by broth microdilution and reported as the MIC and MBC. Hemolytic activities of the transition metal-complexes as well as toxicity toward Vero cells were also measured.

There is a tremendous desire to attribute causes to weather and climate events that is often challenging from a physical standpoint. Headlines attributing an event solely to either human-induced climate change or natural variability can be misleading when both are invariably in play. The conventional attribution framework struggles with dynamically driven extremes because of the small signal-to-noise ratios and often uncertain nature of the forced changes. Here, we suggest that a different framing is desirable, which asks why such extremes unfold the way they do.
