Aspirin may reduce the risks of reoccurring blood clots

Aspirin may reduce the risks of reoccurring blood clots

Aspirin may be a promising alternative for those who can’t take long-term anticoagulant drugs that prevent clots from reoccurring in the veins, according to new research in the American Heart Association journal Circulation. In a combined analysis of two similar independent studies, 1,224 patients who received 100 mg of aspirin a day to treat blood clots were monitored for at least two years. Continue reading

Deletion predicts survival in advanced non-small cell lung cancer

Deletion predicts survival in advanced non-small cell lung cancer

Bcl-2-like protein 11 (BIM) deletion in advanced non-small cell lung cancer (NSCLC) is associated with shorter progression free survival (PFS) in epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) or chemotherapy treated Asian patients. Continue reading

Study of self-awareness in MS has implications for rehabilitation

Study of self-awareness in MS has implications for rehabilitation

A new study of self-awareness by Kessler Foundation researchers shows that persons with multiple sclerosis (MS) may be able to improve their self-awareness through task-oriented cognitive rehabilitation. The study was epublished ahead of print on July 2 in NeuroRehabilitation . Self-awareness is one’s ability to recognize cognitive problems caused by brain injury. Continue reading

Difficulty assessing effort drives motivation deficits in schizophrenia, study finds

Difficulty assessing effort drives motivation deficits in schizophrenia, study finds

Individuals with schizophrenia often have trouble engaging in daily tasks or setting goals for themselves, and a new study from San Francisco State University suggests the reason might be their difficulty in assessing the amount of effort required to complete tasks. The research, detailed in an article published in the Journal of Abnormal Psychology , can assist health professionals in countering motivation deficits among patients with schizophrenia and help those patients function normally by breaking up larger, complex tasks into smaller, easier-to-grasp ones Continue reading

Teen sleeplessness piles on risk for obesity

Teen sleeplessness piles on risk for obesity

Teenagers who don’t get enough sleep may wake up to worse consequences than nodding off during chemistry class. According to new research, risk of being obese by age 21 was 20 percent higher among 16-year-olds who got less than six hours of sleep a night, compared with their peers who slumbered more than eight hours. (The Centers for Disease Control and Prevention recommends nine to ten hours of sleep for teenagers.) Researchers at the Mailman School of Public Health at Columbia University and the University of North Carolina Gillings School of Public Health are the first to examine the effect of sleeplessness on obesity in teenagers over time, providing the strongest evidence yet that lack of sleep raises risk for an elevated BMI Continue reading

Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Pigs’ hearts transplanted into baboon hosts remain viable more than a year

Investigators from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH) have successfully transplanted hearts from genetically engineered piglets into baboons’ abdomens and had the hearts survive for more than one year, twice as long as previously reported. This was achieved by using genetically engineered porcine donors and a more focused immunosuppression regimen in the baboon recipients, according to a study published in The Journal of Thoracic and Cardiovascular Surgery , an official publication of the American Association for Thoracic Surgery. Cardiac transplantation is the treatment of choice for end stage heart failure. Continue reading

Ebola outbreak highlights global disparities in health-care resources

Ebola outbreak highlights global disparities in health-care resources

The outbreak of Ebola virus disease that has claimed more than 1,000 lives in West Africa this year poses a serious, ongoing threat to that region: the spread to capital cities and Nigeria — Africa’s most populous nation — presents new challenges for healthcare professionals. The situation has garnered significant attention and fear around the world, but proven public health measures and sharpened clinical vigilance will contain the epidemic and thwart a global spread, according to a new commentary by Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Continue reading

Mouth bacteria can change its diet, supercomputers reveal

Mouth bacteria can change its diet, supercomputers reveal

Bacteria inside your mouth drastically change how they act when you’re diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, diabetes, and Crohn’s disease. Marvin Whiteley, professor of molecular biosciences and director of the Center for Infectious Disease at The University of Texas at Austin, led the study published in April 2014 in the journal mBio .

Vaccine alternative protects mice against malaria

Vaccine alternative protects mice against malaria

A study led by Johns Hopkins Bloomberg School of Public Health researchers found that injecting a vaccine-like compound into mice was effective in protecting them from malaria. The findings suggest a potential new path toward the elusive goal of malaria immunization. Mice injected with a virus genetically altered to help the rodents create an antibody designed to fight the malaria parasite produced high levels of the anti-malaria antibody. Continue reading

Long-sought drug candidate can halt tumor growth, scientists demonstrate

Long-sought drug candidate can halt tumor growth, scientists demonstrate

It’s a trick any cat burglar knows: to open a locked door, slide a credit card past the latch. Scientists at The Scripps Research Institute (TSRI) tried a similar strategy when they attempted to disrupt the function of MYC, a cancer regulator thought to be “undruggable.” The researchers found that a credit card-like molecule they developed somehow moves in and disrupts the critical interactions between MYC and its binding partner.
