Researchers predicted when cholera epidemic in Yemen would peak

Hokkaido University scientists have developed a new mathematical model which accurately forecasted that a devastating cholera epidemic in Yemen would peak by early July, the 26th week of 2017 and the cumulative incidence would be the order of 700-800 thousand cases. Cholera, which is caused by the bacterium Vibrio cholerae, infects the small intestine through

Sedentary behavior increases risk of death for frail, inactive adults

Sedentary behaviours are associated with adverse health outcomes in middle-aged and older adults, even among those who exercise. We examined whether the degree of frailty affects the association between sedentary behaviours and higher risk of mortality. RESULTS: We found that for people with low levels of frailty (frailty index score ≤ 0.1), sedentary time was

1 in 12 doctors accepts payment from pharmaceutical companies related to opioids

One in twelve physicians -- and nearly one in five family medicine physicians -- accepted payments from pharmaceutical companies related to opioids, according to a new study out of Boston Medical Center's Grayken Center for Addiction Medicine. This is the first large-scale, national study of industry payments involving opioids and suggests that pharmaceutical companies may

Breakthrough device heals organs with a single touch

COLUMBUS, Ohio – Researchers at The Ohio State University Wexner Medical Center and Ohio State’s College of Engineering have developed a new technology, Tissue Nanotransfection (TNT), that can generate any cell type of interest for treatment within the patient’s own body. This technology may be used to repair injured tissue or restore function of aging

Tiny implantable “seeds” of tissue produce fully functional livers

Many diseases, including cirrhosis and hepatitis, can lead to liver failure. More than 17,000 Americans suffering from these diseases are now waiting for liver transplants, but significantly fewer livers are available. To help address that shortage, researchers at MIT, Rockefeller University, and Boston University have developed a new way to engineer liver tissue, by organizing

One in three cases of dementia preventable

This remarkable fact was part of a report by the first Lancet Commission on Dementia Prevention and Care that was presented at the Alzheimer’s Association International Conference (AAIC) 2017 and published in The Lancet. The report also highlighted the beneficial effects of nonpharmacologic interventions such as social contact and exercise for people with dementia. “There’s been a great

Decline in financing could undermine malaria efforts

Researchers at the University of California, San Francisco Global Health Group suggest that while government funding for malaria elimination has been increasing in many affected countries since 2000, the increase in government financing does not fully bridge the gap from a decline in external funding that emerged in 2010. Lack of funding or inefficient use

Meditation and yoga can ‘reverse’ DNA reactions which cause stress, new study suggests

Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don’t simply relax us; they can ‘reverse’ the molecular reactions in our DNA which cause ill-health and depression, according to a study by the universities of Coventry and Radboud. The research, published today in the journal Frontiers in Immunology, reviews over a decade of studies

Designer Viruses Stimulate the Immune System to Fight Cancer

Swiss scientists have created artificial viruses that can be used to target cancer. These designer viruses alert the immune system and cause it to send killer cells to help fight the tumor. The results, published in the journal Nature Communications, provide a basis for innovative cancer treatments. Most cancer cells only provoke a limited reaction

‘Exercise-in-a-pill’ boosts athletic endurance by 70 percent

Salk Institute scientists, building on earlier work that identified a gene pathway triggered by running, have discovered how to fully activate that pathway in sedentary mice with a chemical compound, mimicking the beneficial effects of exercise, including increased fat burning and stamina. The study, which appears in Cell Metabolism on May 2, 2017, not only

Artificial Intelligence May Help Diagnose Tuberculosis in Remote Areas

Researchers are training artificial intelligence models to identify tuberculosis (TB) on chest X-rays, which may help screening and evaluation efforts in TB-prevalent areas with limited access to radiologists, according to a new study appearing online in the journal Radiology. According to the World Health Organization, TB is one of the top 10 causes of death

Vaccination gaps lead to dangerous measles outbreaks in Europe

Gaps in vaccination coverage against measles have led to several outbreaks of the highly-contagious disease in Europe in the past year, with both children and young adults affected, health officials said on Monday. During the first two months of 2017, more than 1,500 measles cases were reported from 14 European countries due to "an accumulation

Ebola virus response: experiences and lessons from Sierra Leone

It’s 18 months since Sierra Leone was declared Ebola free after a two-year outbreak that left 4,000 people dead. While the outbreak might be over, its effects will persist for many years. In the small nation with a population of just 7 million many lost relatives and friends to the disease. And its economy which

Patients don’t know how to best manage their cholesterol

Most people with high cholesterol are not sure how to manage the potentially deadly condition, according to a survey from the American Heart Association. Nearly one in three American adults has high levels of LDL cholesterol, according to AHA statistics. It’s a serious health risk, because too much LDL — or “bad” — cholesterol can

Potential New Treatment to Treat and Stop Progression of Cystic Fibrosis

Researchers from the George Washington University (GW), the University of Perugia, and the University of Rome have discovered a potential new drug to treat and stop the progression of cystic fibrosis. Thymosin α1 (Tα1) is a novel therapeutic single molecule-based therapy that not only corrects genetic and tissue defects, but also significantly reduces inflammation seen

The first live-attenuated vaccine candidate completely protects against Zika infection

GALVESTON, Texas –The first live-attenuated Zika vaccine still in the development stage completely protected mice against the virus after a single vaccination dose, according to new research from The University of Texas Medical Branch at Galveston and Instituto Evandro Chagas at the Ministry of Health in Brazil. The findings are currently available in Nature Medicine.
