Serotonin enhances the impact of health information on food choice

Serotonin has been implicated in promoting self-control, regulation of hunger and physiological homeostasis, and regulation of caloric intake. However, it remains unclear whether the effects of serotonin on caloric intake reflect purely homeostatic mechanisms, or whether serotonin also modulates cognitive processes involved in dietary decision making. We investigated the effects of an acute dose of the serotonin reuptake inhibitor citalopram on choices between food items that differed along taste and health attributes, compared with placebo and the noradrenaline reuptake inhibitor atomoxetine. Twenty-seven participants attended three sessions and received single doses of atomoxetine, citalopram, and placebo in a double-blind randomised cross-over design. Relative to placebo, citalopram increased choices of more healthy foods over less healthy foods. Citalopram also increased the emphasis on health considerations in decisions. Atomoxetine did not affect decision making relative to placebo. The results support the hypothesis that serotonin may influence food choice by enhancing a focus on long-term goals. The findings are relevant for understanding decisions about food consumption and also for treating health conditions such as eating disorders and obesity.M.J.C. was supported by a Sir Henry Wellcome Postdoctoral Fellowship (092217/Z/10/Z) and a Wellcome Trust ISSF award.

The prevalence of radiographic vertebral fractures in Mexican men

The prevalence of radiographically ascertained vertebral fractures in a random sample of 413 in Mexican men is 9.7% (95% CI 6.85–12.55). Increase of vertebral fracture rises with age from 2.0% in the youngest group (50–59 years) to 21.4% in the oldest group (80 years and over). This is the first population-based study of vertebral fractures in Mexican men using a standardized methodology reported in other studies. The presence of radiographic vertebral fractures increases with age. This same pattern was found in Mexican women with steady age increments, but the higher prevalence of fractures in women starts at age 70, whereas in men, the higher prevalence starts a decade later (80 years and over). The standardized prevalence per 1,000 men 50 years and over in the Mexican population for the year 2005 is 65.8 (95% CI 29.9–105.5), and it is 68.6 (95% CI 32.2–108.7) in the US population for the year 2000

Counterfeit drugs and the online pharmaceutical trade, a threat to public safety

Counterfeit pharmaceuticals are a serious and ever-growing threat to public safety. Monitoring the trade is difficult, resulting in the precise scale of the problem being unknown, however evidence shows that it is not just lifestyle drugs that are targeted nowadays. Adverse health problems, including fatalities, have resulted from consumers self-medicating with counterfeit products. Without efforts to enhance the public's knowledge, the problem will continue to persist. The internet is facilitating the trade by providing counterfeiters with a large consumer base and limited risks. The dark net within it allows for anonymous transactions between manufacturer, distributer and consumer. While some online pharmacies are legitimate, there are a growing number of those that are unverified which sell dangerous counterfeit products. Both the packaging and medication are becoming increasingly sophisticated, making it difficult for consumers and law enforcement to identify them without chemical analysis. Counterfeit batches have also been detected in established legal trade routes whereby they are able to, if undetected, end up in high street pharmacies and hospitals. Multiple organisations have set up worldwide operations to dismantle the trade however this is a complex and evolving problem that without significant changes to legislation may never be fully

Randomised controlled trial and health economic evaluation of the impact of diagnostic testing for influenza, respiratory syncytial virus and Streptococcus pneumoniae infection on the management of acute admissions in the elderly and high-risk 18- to 64-year-olds

People over the age of 60 years account for almost half of the 16.8 million hospital admissions in England from 2009 to 2010. During 2009-10, respiratory infections accounted for approximately 1 in 30 hospital admissions and 1 in 20 of the 51.5 million bed-days.HTA ProgrammeNational Institute for Health Research (NIHR
