Missing protein explains link between obesity and diabetes

Singapore, 30 June 2014—Scientists from the Institute of Molecular and Cell Biology (IMCB), a research institute under the Agency for Science, Technology and Research (A*STAR), have discovered that obese individuals lack a protein that is essential for regulating blood glucose levels, causing them to face higher risks of developing diabetes. The protein is one of the first molecular links found between obesity to diabetes and is potentially a target for treatment or prevention of diabetes in obese individuals.

Joint education standards help GI, hepatology programs meet accreditation requirements

Bethesda, MD (June 30, 2014) — A team of representatives from five gastroenterology and hepatology societies have created a toolbox designed to help gastroenterology training directors meet the Accreditation Council for Graduate Medical Education (ACGME) Internal Medicine Subspecialty Reporting Milestones requirements while training fellows to independently care for patients. Thirteen core tasks, known as "entrustable professional activities," or EPAs, have been identified that define the work of gastroenterologists and hepatologists.

Water samples teeming with information: Emerging techniques for environmental monitoring

Environmental policy must respond to ever-changing conditions on the ground and in the water, but doing so requires a constant flow of information about the living world.

In a paper published in Science this week, scientists from Stanford's Center for Ocean Solutions, the University of Washington and the University of Copenhagen propose employing emerging environmental DNA (eDNA) sampling techniques that could make assessing the biodiversity of marine ecosystems – from single-cell critters to great white sharks – as easy as taking a water sample.

Ceremonial PTSD therapies favored by Native American veterans

PULLMAN, Wash. — Native American veterans battling Post Traumatic Stress Disorder find relief and healing through an alternative treatment called the Sweat Lodge ceremony offered at the Spokane Veterans Administration Hospital.

In the Arizona desert, wounded warriors from the Hopi Nation can join in a ceremony called Wiping Away the Tears. The traditional cleansing ritual helps dispel a chronic "ghost sickness" that can haunt survivors of battle.

Gene variants found that increase pain sensation after common childhood surgery

In the first genome-wide analysis of postsurgical pain in children, pediatric researchers identified variations in genes that affect a child's need for pain-control drugs. The findings suggest that at some point physicians may calibrate pain-medication dosages according to a child's individual genetic makeup.

It may take guts to cure diabetes

New York, NY (June 30, 2014) — By switching off a single gene, scientists at Columbia University's Naomi Berrie Diabetes Center have converted human gastrointestinal cells into insulin-producing cells, demonstrating in principle that a drug could retrain cells inside a person's GI tract to produce insulin.

The new research was reported today in the online issue of the journal Nature Communications.

Children born to women after fertility treatment at greater risk of psychiatric disorders

Munich, 30 June 2014: Children born to women with fertility problems have a higher risk of psychiatric disorders than naturally conceived children. The increase in risk was described as "modest" by researchers from Denmark, but was found to persist throughout childhood and into young adulthood.

The results, which are presented today at the 30th Annual Meeting of ESHRE in Munich by Dr Allan Jensen of the Danish Cancer Society Research Center at the University of Copenhagen, were derived from a register study of all children born in Denmark between 1969 and 2006.

One-third of knee replacements classified as inappropriate

New research reports that more than one third of total knee replacements in the U.S. were classified as "inappropriate" using a patient classification system developed and validated in Spain. The study, published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR), highlights the need for consensus on patient selection criteria among U.S. medical professionals treating those with the potential need of knee replacement surgery.

Young teens who receive sexts are 6 times more likely to report having had sex

A study from USC researchers provides new understanding of the relationship between "sexting" and sexual behavior in early adolescence, contributing to an ongoing national conversation about whether sexually explicit text messaging is a risk behavior or just a technologically-enabled extension of normal teenage flirtation. The latest research, published in the July 2014 issue of the journal Pediatrics, found that among middle school students, those who reported receiving a sext were 6 times more likely to also report being sexually active.

The outcome of fertility treatments using donor sperm is dependent on the quality of sperm

Munich, 30 June 2014: Despite emerging evidence of a decline in sperm quality with increasing age, an analysis of every first fertility treatment cycle performed in the UK using sperm donation shows that outcome in terms of live birth is not affected by the age of the sperm donor. Results from the study, said its principal investigator Dr Meenakshi Choudhary, from the Newcastle Fertility Centre at Life, Newcastle upon Tyne, United Kingdom, reaffirm the observation that a couple's fertility appears significantly more dependent on the age of the female partner than on that of the male.

Father's ethnic background influences birthweight, study finds

TORONTO, June 30, 2014—A father's ethnic background can influence a child's birthweight, a new study has found.

Previous research by Dr. Joel Ray of St. Michael's Hospital has shown that a mother's ethnic background can influence birthweights, and his team's new study shows the same is true for a father.

Countdown to 2015 and beyond: Fulfilling the health agenda for women and children

The Lancet today [Monday 30 June] publishes a new Review from the Countdown to 2015 collaboration, summarising results from the Countdown 2014 report, examining the data supporting evidence-based decisions in women's and children's health, describing elements of the Countdown process that might inform ongoing efforts to hold the world to account for progress, and listing concrete steps that can be taken now to ensure continued progress for women and children.

A single gene separates aggressive and non-aggressive lymphatic system cancer

WASHINGTON — For a rare form of cancer called thymoma, researchers have discovered a single gene defining the difference between a fast-growing tumor requiring aggressive treatment and a slow-growing tumor that doesn't require extensive therapy.

Marine bacteria are natural source of chemical fire retardants

Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.

Among the chemicals produced by the ocean-dwelling microbes, which have been found in habitats as diverse as sea grasses, marine sediments and corals, is a potent endocrine disruptor that mimics the human body's most active thyroid hormone.

The study is published in the June 29 online issue of Nature Chemical Biology.

NIH-funded researchers extend liver preservation for transplantation

Researchers have developed a new supercooling technique to increase the amount of time human organs could remain viable outside the body. This study was conducted in rats, and if it succeeds in humans, it would enable a world-wide allocation of donor organs, saving more lives.

The research is supported by National Institute of Biomedical Imaging and Bioengineering (NIBIB) and the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK), both parts of the National Institutes of Health.
