A new study finds that rising placebo responses may play a part in the increasingly high failure rate for clinical trials of drugs designed to control chronic pain caused by nerve damage. Surprisingly, however, the analysis of clinical trials conducted since 1990 found that the increase in placebo responses occurred only in trials conducted wholly in the U.S.; trials conducted in Europe or Asia showed no changes in placebo responses over that period.

Cancer specialists have long looked at genetic mutations and DNA copy changes to help predict patient survival and drug sensitivity. A study led by The University of Texas MD Anderson Cancer Center has opened up yet another avenue for understanding the biological reasons why some people live longer or respond better to treatment - RNA editing events.

A pair of studies by researchers at the University of Massachusetts Medical School, the University of Trento in Italy, and the University of Geneva in Switzerland, point to a promising new anti-retroviral strategy for combating HIV-1. The two studies, published online in Nature, show that the host cell membrane proteins SERINC5 and SERINC3 greatly reduce the virulence of HIV-1 by blocking the ability of the virus to infect new cells.

Choosing the right antidepressant can be a daunting task. With so many choices and such unpredictability in their individual effects, patients with depression often spend months or years casting about for the right medication, while clinicians are often uneasy or unwilling to offer options other than their preferred prescriptions.

Aspirin improves survival in patients with tumours situated throughout the gastrointestinal (GI) tract, results from a large study in The Netherlands show. This is the first time that survival data from patients with tumours in different GI locations have been analysed at the same time; previously, only one type of cancer, usually colorectal, was studied. The results of the study, involving nearly 14,000 patients, may lead to new insights regarding the use of aspirin in GI cancer say the researchers.
