Study links sex hormone levels in the blood to risk of sudden cardiac arrest
Measuring the levels of sex hormones in patients' blood may identify patients likely to suffer a sudden cardiac arrest, a heart rhythm disorder that is fatal in 95 percent of patients.

Enzyme controlling metastasis of breast cancer identified
Researchers at the University of California, San Diego School of Medicine have identified an enzyme that controls the spread of breast cancer. The findings, reported in the current issue of PNAS, offer hope for the leading cause of breast cancer mortality worldwide. An estimated 40,000 women in America will die of breast cancer in 2014, according to the American Cancer Society.

‘Prepped’ by tumor cells, lymphatic cells encourage breast cancer cells to spread
Breast cancer cells can lay the groundwork for their own spread throughout the body by coaxing cells within lymphatic vessels to send out tumor-welcoming signals, according to a new report by Johns Hopkins scientists.

Seatbelt laws encourage obese drivers to buckle up
University of Illinois researchers have found a possible way to mitigate one often-overlooked obesity risk: not buckling up in the car. A new study found that increasing the obesity rates are associated with a decrease in seatbelt usage. However, these effects can be mitigated when seatbelt laws are in effect.

Sabotage as therapy: Aiming lupus antibodies at vulnerable cancer cells
Yale Cancer Center researchers may have discovered a new way of harnessing lupus antibodies to sabotage cancer cells made vulnerable by deficient DNA repair. The study, led by James E. Hansen, M.D., assistant professor of therapeutic radiology at Yale School of Medicine, found that cancer cells with deficient DNA repair mechanisms (or the inability to repair their own genetic damage) were significantly more vulnerable to attack by lupus antibodies.

Microphysiological systems will revolutionize experimental biology and medicine
The September 2014 Annual Thematic Issue of Experimental Biology and Medicine is devoted to 'The biology and medicine of microphysiological systems.' Papers by participants in the NIH Microphysiological Systems Program describe MPS as in vitro models for bone/cartilage, brain, gastrointestinal tract, lung, liver, microvasculature, reproductive tract, skeletal muscle, and skin; the interconnection of MPS to support physiologically based pharmacokinetics and drug discovery and screening; and the microscale technologies that regulate stem cell differentiation.

Scripps Florida scientists make diseased cells synthesize their own drug
In a new study that could ultimately lead to many new medicines, scientists from the Florida campus of The Scripps Research Institute have adapted a chemical approach to turn diseased cells into unique manufacturing sites for molecules that can treat a form of muscular dystrophy.

New name for symptoms associated with menopause
Experts who reviewed the terminology associated with genitourinary tract symptoms related to menopause -- currently referred to as vulvovaginal atrophy -- have agreed that the term genitourinary syndrome of menopause is a medically more accurate, all-encompassing, and a more publicly acceptable term. Their thoughts are published in a recent Journal of Sexual Medicine article.

A handsome face could mean lower semen quality
Contrary to what one might expect, facial masculinity was negatively associated with semen quality in a recent Journal of Evolutionary Biology study. As increased levels of testosterone have been demonstrated to impair sperm production, this finding may indicate a trade-off between investments in secondary sexual signaling (i.e. facial masculinity) and fertility.

Underwater grass comeback bodes well for Chesapeake Bay
The Susquehanna Flats, a large bed of underwater grasses in the upper Chesapeake Bay, virtually disappeared after Tropical Storm Agnes more than 40 years ago. The grasses mysteriously began to come back in the early 2000s. Today the bed is one of the biggest and healthiest in the Bay, spanning some 20 square miles. Scientists at the University of Maryland Center for Environmental Science are figuring out what's behind the comeback.

Patient Safety in Surgery
More than one-third of booked operations are re-booked
More than one-third of all planned orthopedic surgery procedures are re-booked, postponed or cancelled completely. The most common reasons are cancellation at the patient's own request or emergency cases having to be prioritized. These are the findings of a study carried out by the Sahlgrenska Academy, University of Gothenburg, Sweden in association with Sahlgrenska University Hospital.

Discovery hints at why stress is more devastating for some
Some take stress in stride; others struggle with it, even developing psychiatric disorders. New research at Rockefeller University has identified the molecular origins of this so-called stress gap in mice. The results could contribute to a better understanding of the development of depression and other disorders brought on by stress.

Cannabis withdrawal symptoms common among adolescents treated for substance use disorder
Although cannabis -- commonly known as marijuana -- is broadly believed to be nonaddictive, a study by Massachusetts General Hospital investigators found that 40 percent of cannabis-using adolescents receiving outpatient treatment for substance use disorder reported experiencing symptoms of withdrawal, which are considered a hallmark of drug dependence.

Researchers examine effectiveness of blocking nerve to help with weight loss
Among patients with morbid obesity, blocking the vagus nerve, which plays a role with appetite and metabolism, did not meet pre-specified efficacy objectives compared to a control group, although the intervention did result in greater weight loss, according to a study in the Sept. 3 issue of JAMA.

Study finds change in type of procedure most commonly used for bariatric surgery
In an analysis of the type of bariatric surgery procedures used in Michigan in recent years, sleeve gastrectomy (SG) surpassed Roux-en-Y gastric bypass in 2012 as the most common procedure performed for patients seeking this type of surgery, and SG became the predominant bariatric surgery procedure for patients with type 2 diabetes, according to a study in the Sept. 3 issue of JAMA.

Increase seen in use of double mastectomy
Among women diagnosed with early-stage breast cancer in California, the percentage undergoing a double mastectomy increased substantially between 1998 and 2011, although this procedure was not associated with a lower risk of death than breast-conserving surgery plus radiation, according to a study in the Sept. 3 issue of JAMA. The authors did find that surgery for the removal of one breast was associated with a higher risk of death than the other options examined in the study.

Comparison of named diet programs finds little difference in weight-loss outcomes
In an analysis of data from nearly 50 trials including about 7,300 individuals, significant weight loss was observed with any low-carbohydrate or low-fat diet, with weight loss differences between diet programs small, findings that support the practice of recommending any diet that a patient will adhere to in order to lose weight, according to a study in the Sept. 3 issue of JAMA.

NYU study compares consequences of teen alcohol and marijuana use
Alcohol use was more commonly reported to compromise relationships with friends and significant others (e.g., boyfriends); it was also reported to lead to more regret, particularly among females. Marijuana use was more commonly reported to compromise relationships with teachers or supervisors, result in less energy or interest, and result in lower school or job performance.

Community music programs enhance brain function in at-risk children
A new Northwestern University study provides the first direct evidence that a community music program for at-risk youth has a biological effect on children's developing nervous systems. Two years of music lessons improved the precision with which the children's brains distinguished similar speech sounds, a neural process that is linked to language and reading skills. One year of training, however, was insufficient to spark changes in the nervous system.
