Combo pill alone and with aspirin lowers heart disease risk

A 'polypill' is a single pill that includes multiple medications to control more than one health risk factor (such as heart disease, high blood pressure, high cholesterol, Type 2 diabetes, kidney disease, stroke). In this large, international trial, the polypill included blood pressure and cholesterol lowering medications for people at risk for heart disease. Results from the randomized, placebo-controlled trial show that the combination of a polypill plus aspirin reduced cardiovascular disease by 31%, and the polypill without aspirin reduced CVD by 21%.

Clinicians who prescribe unnecessary antibiotics fuel future antibiotic use

Receipt of antibiotics for acute respiratory infections makes it more likely that patients and their families will seek care and receive antibiotics for future respiratory viral infections. In the year after their visit, patients randomly assigned to clinicians who prescribed more antibiotics got 15 percent more antibiotics for viral respiratory infections compared with patients seen by clinicians who prescribed the fewest antibiotics. Antibiotics work against bacteria but not against viruses, and improper use can make bacteria resistant to these drugs.

Breakdown of gene coordination during aging suggests a substantial challenge to longevity

Researchers report evidence that supports, for the first time, a longstanding theory on the aging process in cells. Using a novel approach from physics, they developed a computational method that quantifies the coordination level between different genes. With this approach, they measured the gene activity of individual cells and compared cells from old and young subjects, discovering phenomena never before observed.

'BAH-code' reader senses gene-silencing tag in cells

Researchers have identified an evolutionarily conserved pathway responsible for 'closing down' gene activity in the mammalian cell. The finding is closely related to the Polycomb pathway defined decades ago by a set of classic genetic experiments carried out in fruit flies. They repor the BAHCC1 protein is critically involved in silencing genes and acts as an integral component of the Polycomb gene-repressive pathway in mammalian cells.
