Women under-represented in academic medicine

Women are under-represented in academic medicine resulting in a waste of public investment due to loss of research talent. Writing in the July issue of the Journal of the Royal Society of Medicine, authors of an essay on women and academic medicine say that as a consequence of female under-representation, some areas of medicine are under-researched at a cost to patients and society. Discriminatory practices and unconscious bias, they say, continue to occur in academic medicine, despite a substantial fall in traditional discrepancies between men and women in medicine in recent years.

Heart health benefits of light drinking brought into question

A reduction in alcohol consumption, even for light-to-moderate drinkers, could be linked to improved cardiovascular health, including a reduced risk of coronary heart disease, lower body mass index and blood pressure, according to new research published in The BMJ.

These latest findings challenge the results of previous observational studies which found that the consumption of light-to-moderate amounts of alcohol (12-25 units per week) may have a protective effect on cardiovascular health.

Injected vaccine could help eradicate polio

Re-introducing a type of polio vaccine that fell out of favour in the 1960s could hasten eradication of the disease, according to new research.

The study, by Imperial College London and the Christian Medical College in Vellore, India, suggests that the injected polio vaccine (IPV), which is rarely used today in countries affected by polio, could provide better and longer lasting protection against infection if used in combination with the more commonly used live oral polio vaccine (OPV).

The findings are published today in The Lancet.

Extinct sea scorpion gets a Yale eye exam, with surprising results

Poor peepers are a problem, even if you are a big, bad sea scorpion.

One minute, you're an imperious predator, scouring the shallow waters for any prey in sight. The next, thanks to a post-extinction eye exam by Yale University scientists, you're reduced to trolling for weaker, soft-bodied animals you stumble upon at night.

Despite setback, 'Mississippi Baby' represents significant breakthrough in effort to end AIDS

Washington, D.C.—July 10, 2014—In response to today's announcement that the "Mississippi Baby," believed to have been functionally cured of HIV, has now been found to have detectable levels of the virus, the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF) expresses disappointment in this setback but remains hopeful that the scientific breakthrough that allowed the child's HIV levels to remain undetectable for more than two years will continue to help researchers understand how to control HIV and ultimately develop a cure.

Active shooter training increases comfort level of emergency responders

(Boston) – Emergency Medical Service (EMS) responders felt better prepared to respond to an active shooter incident after receiving focused tactical training according to a new study in the journal Prehospital and Disaster Medicine. This is the first study to specifically examine the EMS provider comfort level with respect to entering a scene where a shooter has not yet been neutralized or working with law enforcement personnel during that response.

Scorpions are master architects, according to new research from Ben-Gurion University

BEER-SHEVA, Israel – Ben-Gurion University of the Negev scientists have discovered that scorpions create a platform in their burrows where they warm up before the evening hunt.

As ectothermic animals, scorpions rely on energy from the environment to regulatetheir internal temperature. The researchers believe that this platform provides a safe, warm spot for the scorpions to increase their body temperature before they leave their hiding places to forage at night.

Scripps Florida scientists shed new light on nerve cell growth

JUPITER, FL, July 10, 2014 – Amidst the astounding complexity of the billions of nerve cells and trillions of synaptic connections in the brain, how do nerve cells decide how far to grow or how many connections to build? How do they coordinate these events within the developing brain?

In a new study, scientists from the Florida campus of The Scripps Research Institute (TSRI) have shed new light on these complex processes, showing that a particular protein plays a far more sophisticated role in neuron development than previously thought.

New study shows drinking alcohol provides no heart health benefit

PHILADELPHIA – Reducing the amount of alcoholic beverages consumed, even for light-to-moderate drinkers, may improve cardiovascular health, including a reduced risk of coronary heart disease, lower body mass index (BMI) and blood pressure, according to a new multi-center study published in The BMJ and co-led by the Perelman School of Medicine at the University of Pennsylvania. The latest findings call into question previous studies which suggest that consuming light-to-moderate amounts of alcohol (0.6-0.8 fluid ounces/day) may have a protective effect on cardiovascular health.

Study looks at how Twitter can be used to address specific health issues

Childhood obesity is one of the top public health concerns in the United States, with 32 percent of youths aged 2-19 classified as obese as of 2012. As health problems such as childhood obesity grow, individuals and organizations have taken to Twitter to discuss the problem.

A new study, led by Jenine K. Harris, PhD, assistant professor at the Brown School at Washington University in St. Louis, examined the use of the hashtag #childhoodobesity in tweets to track Twitter conversations about the issue of overweight kids.

'Mississippi Baby' now has detectable HIV, researchers find

The child known as the "Mississippi baby"—an infant seemingly cured of HIV that was reported as a case study of a prolonged remission of HIV infection in The New England Journal of Medicine last fall—now has detectable levels of HIV after more than two years of not taking antiretroviral therapy without evidence of virus, according to the pediatric HIV specialist and researchers involved in the case.

It's Your Game ... Keep It Real reduces dating violence among minority youth

HOUSTON – (July 10, 2014) – New research from The University of Texas Health Science Center at Houston (UTHealth) shows that It's Your Game…Keep it Real (IYG), a health education program designed to delay sexual behavior and promote healthy dating relationships, can significantly reduce dating violence behaviors among minority youth.

On the link between periodontitis and atherosclerosis

Chronic oral infection with the periodontal disease pathogen, Porphyromonas gingivalis, not only causes local inflammation of the gums leading to tooth loss but also is associated with an increased risk of atherosclerosis. A study published on July 10th in PLOS Pathogens now reveals how the pathogen evades the immune system to induce inflammation beyond the oral cavity.

New research finds ocean's most abundant organisms have clear daily cycles

Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean microbes have their own daily cycles—not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times.

Window of opportunity against HIV comes from 'fitness bottleneck'

New research on HIV transmission shows that viral fitness is an important basis of a "genetic bottleneck" imposed every time a new person is infected. The findings define a window of opportunity for drugs or vaccines to prevent or limit infection.

HIV represents evolution on overdrive. Every infected individual contains a swarm of viruses that exhibit variability in their RNA sequence, and new mutations are constantly appearing. Yet nearly every time someone new is infected, this diverse population of viruses gets squeezed down to just one individual.
