Genetic key to lupus shows potential of personalized medicine
DNA sequencing of a lupus patient has identified a specific genetic mutation that is causing the disease, opening the way for personalized treatments. Researchers identified a variant in the TREX1 gene. This mutation caused the patient's cells to produce a molecule called interferon-alpha. Clinical trials are already underway for drugs to target interferon-alpha in adults.

Intimacy a strong motivator for PrEP HIV prevention
Many HIV-negative gay or bisexual men in steady relationships with other HIV-negative men don't always use condoms out of a desire for intimacy.

The difficult question of Clostridium difficile
Clostridium difficile is a major problem as an aetiological agent for antibiotic-associated diarrhea. The mechanism by which the bacterium colonizes the gut during infection is poorly understood, but undoubtedly involves a myriad of components present on the bacterial surface. This study provides some insights that may help in developing a new type of drug to treat the infection.

Opioid users breathe easier with novel drug to treat respiratory depression
People taking prescription opioids to treat moderate to severe pain may be able to breathe a little easier, literally. A study has found that a new therapeutic drug, GAL-021, may reverse or prevent respiratory depression, or inadequate breathing, in patients taking opioid medication without compromising pain relief or increasing sedation.

Key to saving lives: Hands-only CPR
Cardiac arrest – an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia) and disrupts the flow of blood to the brain, lungs and other organs - is a leading cause of death. Each year, over 420,000 out-of-hospital cardiac arrests occur in the United States. When a person has a cardiac arrest, survival depends on immediately getting CPR from someone nearby.

Study of African dust transport to South America reveals air quality impacts
A new study that analyzed concentrations of African dust transported to South America shows large seasonal peaks in winter and spring. These research findings offer new insight on the overall human health and air quality impacts of African dust, including the climate change-induced human health effects that are expected to occur from increased African dust emissions in the coming decades.

Economists: Shale oil 'dividend' could pay for smaller carbon footprint
Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the US's carbon footprint, agricultural economists say. Using an economic model, they found that "spending" part of this dividend on slashing the nation's carbon emissions by about 27 percent -- about the same amount set forth in the U.S. Environmental Protection Agency's recently proposed Clean Power Plan -- would reduce the shale dividend by about half.
