Many mothers have to navigate a sea of advice from family and experts when it comes to feeding their babies. Nonetheless, nutrition educators typically focus only on the mother, even in Latino communities where grandmothers and other older female relatives often play major roles in caring for children.

A new study shows programs to reduce childhood obesity and other nutrition programs should incorporate all family members who regularly take care of children, not just their mothers.

A meta-analysis finds that despite less evidence in the over 75s than in younger patients, statins reduce the risk of vascular events in older people. The research found no adverse effects of statin therapy on non-vascular mortality or cancer.
Statin therapy reduces major vascular events, and a new meta-analysis shows this is the case even in patients over 75 years of age. The research, published in The Lancet, summarises evidence from 28 randomised controlled trials, including 186,854 patients, 14,483 of whom were aged over 75.

E-cigarettes are almost twice as effective as nicotine replacement treatments, such as patches and gum, at helping smokers to quit, according to a clinical trial led by Queen Mary University of London.

The multi-centre trial, which involved almost 900 smokers who also received additional behavioural support, found that 18.0 per cent of e-cigarette users were smoke-free after a year, compared to 9.9 per cent of participants who were using other nicotine replacement therapies.

A study of people who inject drugs found a significant increase in the risk of infective endocarditis, a serious infection of the lining of the heart, possibly linked to increasing use of the opioid hydromorphone. The study is published in CMAJ (Canadian Medical Association Journal).

Infective endocarditis can be life-threatening.

Inmates want to quit smoking but don't have access to smoking cessation programs in state prisons, increasing the risk - especially among black male inmates -- of cancer, heart disease, stroke and other smoking-related diseases, according to Rutgers researchers.

Anyone who has ever put a small child to bed or drifted off in a gently swaying hammock will know that a rocking motion makes getting to sleep seem easier. Now, two new studies reported in Current Biology on January 24, one conducted in young adults and the other in mice, add to evidence for the broad benefits of a rocking motion during sleep. In fact, the studies in people show that rocking not only leads to better sleep, but it also boosts memory consolidation during sleep.

Gender matters when it comes to smoking cessation.

Women are 31 percent less likely to quit smoking successfully, according to the National Institute of Drug Abuse, in part because nicotine replacement therapy is thought to be more effective in male smokers. In contrast, laboratory-based studies suggest that women crave cigarettes more when they experience stress. However, that finding has not been clearly replicated in a real-world setting.

CHICAGO --- Quitting smoking can significantly improve the effectiveness of cancer treatment, according to the U.S. Surgeon General, yet almost half of cancer patients continue to smoke after they've been diagnosed.

A new study from Northwestern Medicine and the Abramson Cancer Center at the University of Pennsylvania found cancer patients have better success quitting and are not as prone to relapsing one year later if they undergo counseling sessions for 24 weeks and take the smoking cessation medication varenicline (e.g. Chantix) for 24 weeks, compared to the routine 12 weeks.

SAN ANTONIO -- Jan. 23, 2019 -- A new Southwest Research Institute study tackles one of the greatest mysteries about Titan, one of Saturn's moons: the origin of its thick, nitrogen-rich atmosphere. The study posits that one key to Titan's mysterious atmosphere is the "cooking" of organic material in the moon's interior.

Boston, MA -- Coronary heart disease (CHD) is the leading cause of death in the U.S., and African Americans are disproportionately affected. Prior studies have investigated how limited access to material resources due to financial hardship may influence health, but the association between that stress caused by financial hardship and coronary heart disease in African Americans has not previously been examined.
