Private or government-subsidized insurance plans determine weight loss after bariatric surgery

Researchers found the biggest determinant of weight loss after bariatric surgery was not how long a patient was on a medically supervised diet program before surgery, but whether or not the patient had private or government-subsidized insurance.

One-in-five surgically eligible patients denied insurance for bariatric surgery, study finds

University of North Carolina researchers found patients who were denied or delayed insurance approval for bariatric surgery, despite being cleared by their medical team, had a mortality rate three times higher than patients who received insurance approval without delay.

Bariatric surgery safer when performed at accredited centers

Bariatric surgery is significantly safer when performed at an accredited center, according to new research presented here at the 30th Annual Meeting for the American Society for Metabolic and Bariatric Surgery during ObesityWeek 2013, the largest international event focused on the basic science, clinical application and prevention and treatment of obesity. The event is hosted by the ASMBS and The Obesity Society.

Gastric bypass dramatically improves multiple cardiovascular risk factors in the long term

New research from the Cleveland Clinic shows most patients with diabetes and obesity who undergo gastric bypass not only experience remission of their diabetes and lose significant weight, but they also reduce their risk of having a heart attack by 40 percent and their risk for suffering a stroke by 42 percent, over a 10-year time horizon.

Scientists identify genetic signature of respiratory syncytial virus

Scientists have identified the genetic signature of respiratory syncytial virus, the leading cause of infant hospitalizations around the world. The work is a key step toward a better understanding of the immune response to RSV, which will aid the development of a vaccine and a tool that could allow physicians to determine the severity of the infection when symptoms first develop. The study, from a team at The Research Institute at Nationwide Children's Hospital, was published this week in PLOS Medicine.

New microbicide gel formulation shows promise for safe vaginal and rectal administration to prevent HIV

Researchers developed a first-of-its-kind microbicide gel formulation that shows promise for safe vaginal and rectal administration to prevent the sexual transmission of human immunodeficiency virus (HIV).

Early detection of breast cancer could soon be possible with blood test

What could someday be the first blood test for the early detection of breast cancer was shown in preliminary studies to successfully identify the presence of breast cancer cells from serum biomarkers, say the Houston Methodist Research Institute scientists who are developing the technology.

Researchers identify gene responsible for Warburg Micro syndrome

A collaborative team of researchers led by researchers at the Medical College of Wisconsin and the University of Edinburgh has identified a gene responsible for Warburg Micro syndrome, a rare genetic disease characterized by eye, brain and endocrine abnormalities. Patients with Warburg Micro syndrome are severely physically and mentally challenged, unable to learn how to walk or speak and become blind and paralyzed from an early age.

Researchers use new approach to parse roles of key mutated protein that causes familial AD

Researchers at the University of California, San Diego School of Medicine have used genetic engineering of human induced pluripotent stem cells to specifically and precisely parse the roles of a key mutated protein in causing familial Alzheimer's disease, discovering that simple loss-of-function does not contribute to the inherited form of the neurodegenerative disorder.

Research sheds light on how protein keeps people organized by promoting orderly skeletal growth

Most people think that their planners or their iPhones keep them organized, when proteins such as liver kinase b1 (Lkb1) actually have a lot more to do with it. New research from postdoctoral fellow Lick Lai in the lab of USC scientist Andy McMahon published in Proceedings of the National Academy of Sciences (PNAS) sheds light on how this important protein keeps people organized on a basic level by promoting orderly skeletal growth and preventing skeletal tumors.

Scientists discover new drug mechanism to reduce risk of infections

Scientists at A*STAR's Singapore Immunology Network (SIgN) have discovered the exact mode of action by plerixafor, a drug commonly prescribed to stimulate immune responses in patients suffering from neutropenia, which causes them to become prone to oral, skin, genital infections and in worst cases, a fatal whole-body infection.

Study finds consistent sleep pattern can reduce risk of illness among adolescents

Newly released findings from Bradley Hospital published in the Journal of Sleep Research have found that acute illnesses, such as colds, flu, and gastroenteritis were more common among healthy adolescents who got less sleep at night. Additionally, the regularity of teens' sleep schedules was found to impact their health.

Copper intake via food and water can accelerate growth of tumors

Copper imbalances have been associated with a number of pathological conditions, including cancer. Publishing in PNAS scientists at EPFL have found that copper in drinking water - given at the maximum levels permitted in public water supplies - accelerated the growth of tumors in mice. On the other hand, reducing copper levels reduced tumor growth.

Lower doses of antimalarial drug effective in reducing malaria transmission

Lower doses of the antimalarial drug primaquine are as effective as higher doses in reducing malaria transmission, according to a study published today in Lancet Infectious Diseases by London School of Hygiene & Tropical Medicine researchers.

Study finds link between alcohol consumption and reduced condom use among college women

A new study from researchers at The Miriam Hospital finds a link between alcohol consumption and reduced condom use among college women. The findings also indicate that women who smoke marijuana with established romantic partners may use condoms less often.

Research may explain why people who take bone-strengthening drugs are at-risk for atypical fractures

Research with baboons at the Texas Biomedical Research Institute may help explain why some people who take bone-strengthening drugs like bisphosphonates are at-risk for atypical fractures in the long bones in their legs.

Researchers create new statistical tools to find clues about cancer from raw data

Researchers at Rice University, Baylor College of Medicine (BCM) and the University of Texas at Austin are working together to create new statistical tools that can find clues about cancer that are hidden like needles in enormous haystacks of raw data.

Researchers exploit power of evolution to create new drug for use against heart disease

An international team of researchers led by the University of Leicester has "harnessed the power of evolution" to create a new drug for possible use against heart disease, inflammation and other illnesses.

Few newly diagnosed high-cholesterol patients get screened for thyroid dysfunction: Study

Despite current guidelines that recommend newly diagnosed high-cholesterol patients have a TSH blood test done to make sure they do not have hypothyroidism, researchers from Boston University School of Medicine and Boston Medical Center have found that only about half of these patients were screened for thyroid dysfunction.

Small molecule compound shows significant success in controlling polyomaviruses

A team of scientists reports that a small molecule compound showed significant success in controlling the infectivity and spread of three polyomaviruses in human cell cultures. To date there has been no medicine approved to treat such viruses, which prey on transplant recipients, people with HIV, and others whose immune systems have been weakened.
