Conflict-of-interest statements made by physicians and scientists in their medical journal articles after they had been allegedly paid by pharmaceutical manufacturers as part of off-label marketing programs are often inadequate, highlighting the deficiencies in relying on author candidness and the weaknesses in some journal practices in ensuring proper disclosure, according to a study by international researchers published in this week's PLOS Medicine. Off-label marketing is the promotion by...

Some young people's expectations that they will not live long, healthy lives may actually foreshadow such outcomes. New research published August 1 in the open access journal PLOS ONE reports that, for American teens, the expectation of death before the age of 35 predicted increased risk behaviors including substance abuse and suicide attempts later in life and a doubling to tripling of mortality rates in young adulthood. The researchers, led by Quynh Nguyen of Northeastern University...

Researchers from the University of Kentucky have designed and discovered a series of highly efficient enzymes that effectively metabolize cocaine. These high-activity cocaine-metabolizing enzymes could potentially prevent cocaine from producing physiological effects, and could aid in the treatment of drug dependency. The results of this study by Chang-Guo Zhan et al are published in the journal PLOS Computational Biology. The effectiveness of the enzymes' work was evaluated through...

Test of captive butterflies shows association between pigment level and flight distance For monarch butterflies, redder wings are correlated with better flight performance, according to research published July 25 in the open access journal PLoS ONE. Previous work has shown that monarch coloring is intended to warn their predators about their bitter taste and toxicity, and that migratory butterflies are darker colored than non-migratory ones, suggesting an association between darker...

Unique arm morphology in Neanderthals was likely caused by scraping activities such as hide preparation, not spear thrusting as previously theorized, according to research published July 18 in the open access journal PLoS ONE. The researchers, led by Colin Shaw of the University of Cambridge, took muscle measurements of modern men performing three different spear thrusting tasks and four different scraping tasks. They found that muscle activity was significantly higher on the left side of...

Chimpanzees use weight to pick the best tool, and monkeys beg more when they're paid attention to, as reported in two independent research reports published July 18 in the open access journal PLoS ONE. In the chimp study, researchers found that the chimpanzees used weight to choose the best hammer to crack open nuts. Nut cracking is one of the most sophisticated instances of tool use in chimpanzees, and learning how to do it has been shown to be very difficult for some chimps. In work led...

Researchers have developed a new metric to measure obesity, called A Body Shape Index, or ABSI, that combines the existing metrics of Body Mass Index (BMI) and waist circumference and shows a better correlation with death rate than do either of these individual measures. The full results are reported July 18 in the open access journal PLoS ONE, and the work was led by Nir Krakauer of City College of New York. The authors analyzed data from over 14,000 US adults taken as part of the...

In this week's PLoS Medicine, Joseph Tucker from the University of North Carolina, Chapel Hill, North Carolina, USA and colleagues lay out a social entrepreneurship for sexual health (SESH) approach that focuses on decentralized community delivery, multisectoral networks, and horizontal collaboration (business, technology, and academia). They argue that while SESH approaches have yet to be widely implemented, they show great promise: "Social marketing and sales of point-of-care,...

In this week's PLoS Medicine, David Osrin of the UCL Institute of Child Health, UK and colleagues report findings from a cluster-randomized trial conducted in Mumbai slums that aimed to evaluate whether facilitator-supported women's groups could improve perinatal outcomes. Their findings indicate that while it is possible to facilitate the discussion of perinatal health care by urban women's groups in the challenging conditions that exist in the slums of Mumbai, there was no measureable...

A hospital-based surveillance study conducted by Ciara O'Reilly of the Centers for Disease Control and Prevention, Atlanta, Georgia, USA and colleagues describes the risk factors for death amongst children who have been hospitalized with diarrhea in rural Kenya. Reporting in this week's PLoS Medicine, the authors found that infections with nontyphoidal Salmonella and with Shigella (but not with rotavirus) were associated with an increased risk of death. The authors state that: "This...
