Philadelphia, Pa. (March 22, 2013) – Every five years, the Crohn's & Colitis Foundation of America (CCFA) gathers top researchers in inflammatory bowel disease (IBD) to set the research agenda for the next five years. The findings and recommendations of these expert workgroups are presented in a series of detailed "Challenges in IBD Research" reports, now available in Inflammatory Bowel Diseases, official journal of the CCFA.

CHICAGO – In a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers reviewed existing literature on smoking and the healing of fractures involving long bones (bones that are longer than they are wide).

The analysis of data from 20 studies found an overall 2.3 times higher risk of nonunion (bones that do not heal properly) in smokers. Similarly, for all fractures, the average time to fracture healing was longer for smokers (32 weeks) than nonsmokers (25.1 weeks).

A study by researchers at Hospital for Special Surgery (HSS) challenges a widely held belief that long nerve grafts do poorly in adults with an axillary nerve injury. Investigators found that the outcomes of long nerve grafts were comparable to those of modern nerve transfers. Both procedures restored function. The axillary nerve supplies the deltoid muscle of the shoulder and an important rotator cuff muscle. It's part of the brachial plexus, a network of nerves that runs down from the neck and across the shoulder.

New research conducted in 10 European cities has estimated that 14% of chronic childhood asthma is due to exposure to traffic pollution near busy roads.

The results are comparable to the burden associated with passive smoking: the World Health Organization estimates that between 4% and 18% of asthma cases in children are linked to passive smoking.

Virginia Tech researchers successfully used a gene disruption technique to change the eye color of a mosquito — a critical step toward new genetic strategies aimed at disrupting the transmission of diseases such as dengue fever.

Energy drinks may increase blood pressure and disturb your heart's natural rhythm, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.

Researchers analyzed data from seven previously published observational and interventional studies to determine how consuming energy drinks might impact heart health.

Eating too much salt contributed to 2.3 million deaths from heart attacks, strokes and other heart-related diseases throughout the world in 2010, representing 15 percent of all deaths due to these causes, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.

Nearly 75 percent of commercial pre-packaged meals and savory snacks for toddlers are high in sodium, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.

The American Heart Association has released new recommendations for policy makers and public health providers to combat heart disease and stroke on a local level.

The "American Heart Association Guide for Improving Cardiovascular Health at the Community Level, 2013 Update" — evidence-based goals, strategies and recommendations for community-based public health interventions — is published in the American Heart Association journal Circulation.

GAINESVILLE, Fla. — A new University of Florida study of nearly 5,000 Haiti bird fossils shows contrary to a commonly held theory, human arrival 6,000 years ago didn't cause the island's birds to die simultaneously.

Scientists have confirmed that the pathogen that causes Lyme Disease—unlike any other known organism—can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that protect the body by starving pathogens of iron.

Though we all desire relief -- from stress, work, or pain -- little is known about the specific emotions underlying relief. New research from the Association for Psychological Science explores the psychological mechanisms associated with relief that occurs after the removal of pain, also known as pain offset relief.

NEW YORK (March 21, 2013) -- More than 50,000 stem cell transplants are performed each year worldwide. A research team led by Weill Cornell Medical College investigators may have solved a major issue of expanding adult hematopoietic stem cells (HSCs) outside the human body for clinical use in bone marrow transplantation -- a critical step towards producing a large supply of blood stem cells needed to restore a healthy blood system.

The over-the-counter anti-inflammatory drug naproxen may also exhibit antiviral activity against influenza A virus, according to a team of French scientists. The finding, the result of a structure-based investigation, is published online ahead of print in the journal Antimicrobial Agents and Chemotherapy.

Dartmouth researchers have taken an important step in the ongoing battle against secondhand tobacco smoke. They have pioneered the development of a breakthrough device that can immediately detect the presence of secondhand smoke and even third-hand smoke.

Smaller and lighter than a cellphone and about the size of a matchbox car, the device uses polymer films to collect and measure nicotine in the air. A sensor chip then records the data on an SD memory card. The technology is described in a new study appearing in the journal Nicotine and Tobacco Research.
