NIH study suggests opioid therapy not effective against chronic pain

NIH study suggests opioid therapy not effective against chronic pain

Health
May 25 (UPI) -- Opioid therapy may not always be effective against chronic pain and could lead to depression, according to a National Institutes of Health Study. The study was conducted by the NIH in collaboration with Montreal's McGill University and published Thursday in the medical journal Pain. Using laboratory rats, the research suggests that pain-induced changes in the brain's opioid receptor system can limit the effectiveness of therapy with the drugs. The study also demonstrates the impact of chronic pain on the brain and its relationship to depression. "We know that people with chronic pain have reduced availability of opioid receptors, the molecules opioid drugs bind to, in the brain," Dr. Mark Pitcher, a researcher at NIH and an author of the study, said in a press release. "W...
10-year study shows obesity increases risk for 12 cancers

10-year study shows obesity increases risk for 12 cancers

Health
May 24 (UPI) -- A new report by the World Cancer Research Fund Thursday links excessive body fat to 12 types of cancers, at a time it says obesity is on the rise globally. The report Diet, Nutrition, Physical Activity and Cancer: a Global Perspective examines a decade of research linking cancer prevention to diet and lifestyle, and is the third to address the subject. The first and second reports were published in 1997 and 2007. Thursday's report found obesity increases humans' risk of getting 12 cancers -- in the mouth, esophagus, stomach, pancreas, gallbladder, liver, colorectum, breast, ovary, endometrium, prostate and kidney. The prevalence of obesity, it said, has increased at a rate faster than ever before. "In 2016, an estimated 1.97 billion adults and over 338 million children an...
Study confirms link between gamma rays, lightning strikes

Study confirms link between gamma rays, lightning strikes

Science
May 17 (UPI) -- A new survey of downward terrestrial gamma ray flashes suggests the rare electromagnetic phenomena is linked with cloud-to-ground lightning. The Telescope Array is an observatory consisting of 507 scintillation surface detectors spread out across a massive expanse of the Utah desert. Between 2014 and 2016, the array detected 10 downward terrestrial gamma ray flashes, or TGFs. The array's observations -- published this week in the Journal of Geophysical Research -- are the first to link TGFs with the beginning of lightning strikes and the first to locate the origin of a TGF inside a thundercloud. TGFs are the highest-energy light waves on the electromagnetic spectrum, and thanks to the Telescope Array, scientists are closer to understanding them. "What's really cool is tha...
Fast-food consumption can increase difficulty getting pregnant, study says

Fast-food consumption can increase difficulty getting pregnant, study says

Health
May 4 (UPI) -- Women who eat fast food-four or more times a week were less likely to conceive within a year and more frequently experience infertility than those who consume a healthy diet, according to a new study.Researchers analyzed the diets of 5,598 women in Australia, New Zealand, Britain and Ireland from November 2004 to February 2011. Their findings were published Friday in the journal Human Reproduction."The findings show that eating a good quality diet that includes fruit and minimizing fast-food consumption improves fertility and reduces the time it takes to get pregnant," Dr. Claire Roberts, a research fellow at the University of Adelaide in Australia, said in a press release.Fast-food, which included burgers, pizza, fried chicken and chips, were bought at fast-food and other t...
Loss of receptor cells can prompt strong itching from a light touch: Study

Loss of receptor cells can prompt strong itching from a light touch: Study

Health
May 4 (UPI) -- A severe reaction to light touching -- often among old people -- occurs because of fewer receptors in the skin, according to a new study with mice.Researchers at Washington University School of Medicine in St. Louis studied severe itching from light tough, even when the skin is under clothing. Their findings, which researchers hope will lead to a treatment for the condition, were published Friday in the journal Science."Itching caused by touch becomes more common as we age and is especially problematic for people with dry skin or who already suffer from chronic itching," senior investigator Dr. Hongzhen Hu, an associate professor of anesthesiology at Washington University, said in a press release. "It can be more than a nuisance, and there are no drugs available to treat thi...
