Cautious optimism as childhood obesity rates in Ireland plateau

Oct 14, 2014

Childhood overweight and obesity rates have plateaued in primary school aged children in the Republic of Ireland, reveals research published today in the open access journal BMC Public Health. The study found that although obesity rates remain high, there is evidence that they have stabilised and may be beginning to fall.

Bottom Line: A study of teenagers suggests there is no association between physical activity (PA) and the development of depressive symptoms later in adolescence.

Dysregulation in orexinergic system associated with Alzheimer disease

Oct 14, 2014

Bottom Line: In patients with Alzheimer disease (AD), increased cerebrospinal fluid levels of orexin, which helps regulate the sleep-wake cycle, may be associated with sleep deterioration, which appears to be associated with cognitive decline.

Using stents to keep neck arteries open is just as effective as invasive neck surgery for long-term prevention of fatal and disabling strokes

Versatile antibiotic found with self-immunity gene on plasmid in staph strain

Oct 14, 2014

A robust, broad spectrum antibiotic, and a gene that confers immunity to that antibiotic are both found in the bacterium Staphylococcus epidermidis Strain 115. The antibiotic, a member of the thiopeptide family of antibiotics, is not in widespread use, partly due to its complex structure, but the investigators, from Brigham Young University, Provo, Utah, now report that the mechanism of synthesis is surprisingly simple. "We hope to come up with innovative processes for large-scale production and derivitization so that new, and possibly more potent versions of the antibiotic can become available, says co-corresponding author Joel S. Griffitts. The research is published ahead of print in Journal of Bacteriology.

Teenage baseball pitchers at risk for permanent shoulder injury

Oct 14, 2014

Young baseball pitchers who throw more than 100 pitches per week are at risk for a newly identified overuse injury that can impede normal shoulder development and lead to additional problems, including rotator cuff tears, according to a new study published online in the journal Radiology.

Study sheds light on factors that may contribute to pancreatic cancer

New research that provides a better understanding of pancreatic cancer may help identify individuals at increased risk. The findings are published early online in Cancer, a peer-reviewed journal of the American Cancer Society.

Slow enteral feeding protocol can reduce instances of death in extreme preterm infants

Oct 14, 2014

A standardized slow enteral feeding (SSEF) protocol significantly reduces the incidence of necrotizing enterocoltis (NEC), or death of intestinal tissue, and death in infants with extremely low birth weight, according to a new study.

Memories of pain during childbirth tied to intensity rather than length of labor

Oct 14, 2014

Childbirth is physically intense and, for many women, it is the most painful experience they will have. And yet, new research shows that the amount of time a woman spends in labor doesn't seem to impact how she remembers her labor pain afterwards. The research, published in Psychological Science, a journal of the Association for Psychological Science, reveals that the peak and end levels of pain women experienced, and whether they received an epidural, impacted their recall of labor pain afterward.

Embryos receive parent-specific layers of information, study shows

Multiple neurodevelopmental disorders have a common molecular cause

Oct 13, 2014

Neurodevelopmental disorders such as Down syndrome and autism-spectrum disorder can have profound, lifelong effects on learning and memory, but relatively little is known about the molecular pathways affected by these diseases. A study published by Cell Press October 9th in the American Journal of Human Genetics shows that neurodevelopmental disorders caused by distinct genetic mutations produce similar molecular effects in cells, suggesting that a one-size-fits-all therapeutic approach could be effective for conditions ranging from seizures to attention-deficit hyperactivity disorder.

Researchers uncover how 'love hormone' regulates sexual behavior

Oct 13, 2014

Oxytocin has been called the "love hormone" because it plays an important role in social behaviors, such as maternal care and pair bonding. In a study published by Cell Press on October 9th in the journal Cell, researchers uncover oxytocin-responsive brain cells that are necessary for female social interest in male mice during estrus-the sexually receptive phase of their cycle. These neurons, found in the prefrontal cortex, may play a role in other oxytocin-related social behaviors such as intimacy, love, or mother-child bonding.
