During the height of the Civil War, the Confederate Surgeon General commissioned a guide to traditional plant remedies of the South, as battlefield physicians faced high rates of infections among the wounded and shortages of conventional medicines. A new study of three of the plants from this guide -- the white oak, the tulip poplar and the devil's walking stick -- finds that they have antiseptic properties.
Getting more exercise than normal - or being more sedentary than usual - for one day may be enough to affect sleep later that night, according to a new study led by Penn State.
In a one-week micro-longitudinal study, the researchers found that when teenagers got more physical activity than they usually did, they got to sleep earlier, slept longer and slept better that night.
People who suffer a stroke caused by bleeding in the brain - known as brain haemorrhage - can take common medicines without raising their risk of another stroke, a major clinical trial has found.
Researchers say the findings are reassuring for the thousands of people who take the medicines to reduce their risk of heart attack and another common type of stroke caused by blood clots in the brain.
Paris, France, 21 May 2019. This PCR statement on paclitaxel drug-coated balloons (DCB) use in peripheral interventions addresses the controversy raised by the meta-analysis of K. Katsanos, MD, PhD (Patras University Hospital, Rion, Greece) and colleagues, published in late 2018. The Katsanos meta-analysis prompted widespread concern in the interventional community by suggesting that treatment with paclitaxel-eluting stents or DCBs for femoropopliteal disease is associated with increased
A team of international scientists--including researchers at the University of St. Andrews, Syracuse University and Royal Holloway, University of London--have demonstrated a new source of food for early life on the planet.
They've never seen animals like hippos and sharks but adults born blind have rich insight into what they look like, a new Johns Hopkins University study found.
"First-person experience isn't the only way to develop a rich understanding of the world around us," says Judy Kim, a doctoral candidate at Johns Hopkins and corresponding author of the study published May 21 in Proceedings of the National Academy of Sciences.
"Essentially, the question is, how do we know what we know?"
Food insecurity, meaning inadequate or insecure access to food because of a lack of money, has worsened in Nunavut communities since the introduction of the federal government's Nutrition North Canada program in 2011, found research published in CMAJ (Canadian Medical Association Journal).
Even before the introduction of Nutrition North Canada, food insecurity was a widespread problem in Nunavut communities, with some of the highest rates of food insecurity in Canada.
A team of economists has concluded that soda taxes serve as a "net good," an assessment based on an analysis of health benefits and consumer behavior. The work, which sees advantages similar to those of long-standing cigarette taxes, also offers policy parameters that it views as more effective than many existing soda taxes.
The analysis, by researchers at New York University, the Wharton School at the University of Pennsylvania, and the University of California, Berkeley, was released today as a National Bureau of Economic Research (NBER) working paper.
Results from a study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, point to the need for improved access to medical care for sexual minority cancer survivors, in particular female survivors. In female cancer survivors, poor access to care is more strongly related to poor quality of life among sexual minorities compared with heterosexuals.
Your smile, and associated oral health, may be a factor for successfully passing through the revolving doors of life. It is your first impression to a stranger, the closing argument to land a job and a major factor to achieving a good quality of life. For those who struggle with substance use disorder, oral health often falls off the precipice of self-care thereby seriously damaging interpersonal skills, while causing poor nutrition, increased oral and general infections and debilitating oral pain.
A new laboratory-based method of estimating outcomes for patients with a severe pulmonary disorder that has no cure can help physicians better provide proper care, referrals, and services for patients at the end of life, according to a new study of more than 17,000 patients from Intermountain Healthcare.
After 20 years of rapid increases in life expectancy at birth, the rate of growth in Australia is now falling behind most other high-income nations, meaning better control of health risk factors such as obesity will be needed if further life expectancy increases are to be achieved, research shows.
Published today by the Medical Journal of Australia, researchers from the University of Melbourne School of Population and Global Health have analysed data for Australia and 26 other high-income countries from 1980-2016.
A study of nearly 300 patients with mild persistent asthma found that inhaled steroids--long considered the gold standard for asthma treatment--were no more effective than placebo in nearly three-fourths of the study patients, all over age 12. Inhaled steroids were better than placebo for a subset of the patients who had high levels of a particular type of inflammatory cells, called eosinophils, in their sputum, but they represented about a fourth of patients enrolled in the trial.
ATS 2019, Dallas, TX -- In addition to suppressing tumors, the protein tuberous sclerosis complex 2 (TSC2) may play a role in preventing or treating pulmonary arterial hypertension (PAH), according to research presented at ATS 2019. Researchers found that a deficiency of this protein produced dysfunctional molecules unable to support cell structure and function, resulted in thickening of pulmonary blood vessels and led to PAH.
PITTSBURGH, May 19, 2019 - Reversibly paralyzing and heavily sedating hospitalized patients with severe breathing problems do not improve outcomes in most cases, according to a National Institutes of Health-sponsored clinical trial conducted at dozens of North American hospitals and led by clinician-scientists at the University of Pittsburgh and University of Colorado schools of medicine.
