A multi-institutional study led by investigators from Massachusetts General Hospital (MGH) and the Broad Institute has identified how the intestinal microbial population of newly diagnosed Crohn's disease patients differs from that of individuals free of inflammatory bowel disease (IBD). In their paper in the March 12 issue of Cell Host and Microbe, the researchers report that Crohn's patients showed increased levels of harmful bacteria and reduced levels of the beneficial bacteria usually found in a healthy gastrointestinal tract.

PROVIDENCE, R.I. – Megan Ranney, M.D., M.P.H., an emergency medicine attending physician at Hasbro Children's Hospital, recently led a study that found a text-message program may be an effective violence prevention tool for at-risk teen girls. The study has been published online in the Journal of Adolescent Health.
Valentine's Day has come and gone. But those images of romance are still everywhere : a happy couple holding hands in an eharmony ad, two lovebirds sharing a tender kiss in a Nikon camera commercial.
Advertising filled with romantic images, featuring "happy togetherness" in magazines and stores as well as on television and websites might resonate with you if you have a special someone. But if you're single, a new study shows you're not buying.
Thin films of spin ice have been shown to demonstrate surprising properties which could help in the development of applications of magnetricity, the magnetic equivalent of electricity.
Published today in Nature Communications, a team of researchers based at the London Centre for Nanotechnology (LCN), in collaboration with scientists from Oxford and Cambridge, found that, against expectations, the Third Law of Thermodynamics could be restored in thin films of the magnetic material spin ice.
NEW ORLEANS─The number of total knee replacement (TKR) procedures continues to climb, as does the number of revision total knee replacement (RTKR) surgeries. In the study, "The Epidemiology of Revision Total Knee Arthroplasty in the United States," presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers used the Nationwide Inpatient Sample (NIS) to evaluate the cause of knee failure for 301,718 revision RTKR surgeries performed between 2005 and 2010.
Implementation of community-based interventions alone is unlikely to be effective for reducing most alcohol-related harms and risky alcohol consumption, according to a study by Australian researchers published in this week's PLOS Medicine. Anthony Shakeshaft and colleagues from the National Drug and Alcohol Research Centre at UNSW (University of New South Wales), report that alcohol-related crime, road-traffic crashes, and hospital inpatient admissions did not differ between communities that did and did not implement community-based interventions.
A large team of experts led by a Johns Hopkins geriatrician reports that efforts to improve the care of older adults and others with complex medical needs will fall short unless public policymakers focus not only on preventing hospital readmission rates, but also on better coordination of community-based "care transitions." Lessons learned from managing such transitions for older patients, they say, may offer a framework for overall improvement.
Patients who received help from a poison center had shorter hospital stays and lower hospital charges among those who are the most expensive to treat, according to a study led by researchers at the University of Illinois at Chicago School of Public Health.
Poison centers provide 24-hour assistance year round to the public and to medical professionals. While studies show that poison centers reduce system-wide costs, their impact on patient outcomes at the hospital level has not been clear, the study's authors report.
Patients brought to hospital emergency departments (EDs) more than once in a year for treatment of opioid drug overdoses are more likely to be hospitalized for overdose and to need respiratory support with a mechanical ventilator. A study conducted by Massachusetts General Hospital (MGH) investigators also identified factors that increased the risk of subsequent overdoses requiring emergency department visits.
PHILADELPHIA — Destruction of insulin-producing beta cells in the pancreas is at the heart of type 1 and type 2 diabetes. "We are looking for ways to make new beta cells for these patients to one day replace daily insulin injections," says Ben Stanger, MD, PhD, assistant professor of Medicine in the Division of Gastroenterology, Perelman School of Medicine at the University of Pennsylvania.
Middle-aged women with rheumatoid arthritis or arthritis resulting from an injury are among the patients most likely to experience serious pain following a knee replacement, researchers from Hospital for Special Surgery (HSS) in New York have found.
LADA (latent autoimmune diabetes in adults) is a form of type 1 diabetes in adulthood. Like the childhood form, the insulin-producing beta cells of the pancreas are destroyed by the body's own immune system. The progression of the illness is relatively slowly, however, with clinical manifestations not appearing until after the age of 30 and the patients not yet requiring insulin therapy to control blood sugar levels at the beginning of the disease. It is therefore often difficult to differentiate between LADA and type 2 diabetes.
When it comes to shopping for gifts, we try to select things we think people both want and need. According to a new study in the Journal of Consumer Research, focusing too much on the gift recipient can lead to giving the gift we were trying to avoid in the first place.
Poor food choices, such as overconsumption of carbonated soft drinks, are an important factor driving the global obesity epidemic and have been linked directly to diabetes and heart disease. While public health agencies are working to help people to make healthier choices, monitoring the effectiveness of these efforts has been costly and difficult. But now, using the same digital data employed by marketers to promote food products, McGill University's David Buckeridge has developed a way for health agencies to track Montreal consumers' food choices, neighborhood by neighborhood.
NEW ORLEANS ─ Hip and knee replacements have long been known to reduce pain and increase mobility in persons with moderate-to-severe arthritis. A study presented at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) also found that total joint replacement (TJR) may reduce the risk for "cardiac events," including heart attack and stroke, and boost long-term survival.
Physical inactivity is a major risk factor for cardiovascular disease.
