Portion Size And Overeating
Date: Apr-19-2013People given large servings of food eat more than those given smaller servings, even after they have been taught about the impact of portion size on consumption, research from the University of New South Wales shows. Learning how to engage in mindful - rather than mindless - eating also did not decrease food intake by a significant amount in those given large servings. The study, published in the Journal of Health Psychology, highlights the need to find new ways to reduce the effect of portion size on overeating...
Digoxin Found To Be Safe Despite Recent Reports
Date: Apr-19-2013A study published in the European Heart Journal found no evidence that digoxin increases mortality in patients with atrial fibrillation (AF), the opposite of results just published by another group in the same journal analyzing the same data. Older patients with AF also often have heart failure, and digoxin is approved to treat both conditions. AF is the most common kind of cardiac arrhythmia, an electrical malfunction that throws off the heart's rhythm and pumping rate. It may cause no symptoms or cause some patients to faint, but is seldom fatal...
Spread Of Breast Cancer Linked To Kisspeptins Which Normally Inhibit Metastasis
Date: Apr-19-2013KISS 1 is a metastasis-suppressor gene which helps to prevent the spread of cancers, including melanoma, pancreatic and ovarian cancers to name a few. But new research from Western University's Schulich School of Medicine & Dentistry shows that kisspeptins - peptide products of KISS1, actually make some breast cancers worse, with a higher tumor grade and metastatic potential. The research is published online in the journal Endocrinology...
Investment In Nursing Helps Magnet Hospitals Achieve Lower Mortality
Date: Apr-19-2013Lower mortality and other improved patient outcomes achieved at designated "Magnet hospitals" are explained partly - but not completely - by better nurse staffing, education, and work environment, reports a study in the May issue of Medical Care. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. "Magnet hospitals have lower mortality because of investments in nursing," comments Matthew D. McHugh, PhD, JD, MPH, RN, of University of Pennsylvania School of Nursing, Philadelphia, lead author of the new report...
New Rules On Financial Relationships Might Slow Medical Innovation
Date: Apr-19-2013Startup companies founded by physician entrepreneurs are an important source of patents used in developing innovative new medical devices, suggests a study in the May issue of Medical Care. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health...
84 Percent Of Lung Cancer Patients Taking Crizotinib Found To Have Low Testosterone
Date: Apr-19-2013A previous study by the University of Colorado Cancer Center reported the common side effect of low testosterone in men treated with the recently approved lung cancer agent, crizotinib. A new study published this week in the journal Cancer confirms this finding in a multi-national sample, details the mechanism of reduced testosterone, and provides promising preliminary evidence that widely available hormone replacement therapies can alleviate this side effect in many patients...
Neuroscientific Evidence And The Law
Date: Apr-19-2013Brain scans are increasingly able to reveal whether or not you believe you remember some person or event in your life. In a new study presented at a cognitive neuroscience meeting, researchers used fMRI brain scans to detect whether a person recognized scenes from their own lives, as captured in some 45,000 images by digital cameras. The study is seeking to test the capabilities and limits of brain-based technology for detecting memories, a technique being considered for use in legal settings...
Exposure To Traffic Pollution Increases Risk Of Heart Disease
Date: Apr-19-2013People who are exposed to fine particle matter (PM) air pollution from traffic pollution for a prolonged period of time are at an increased risk of developing atherosclerosis, according to a new study presented at the EuroPRevent 2013 congress in Rome. This isn't the first time that road traffic has been linked with heart disease, a previous study conducted in Denmark in 2012 identified that traffic noise is significantly associated with risk of heart attack...
Overworked And Stressed Out? Look On The Bright Side - Some Stress Is Good For You
Date: Apr-19-2013"You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley. "Some amounts of stress are good to push you just to the level of optimal alertness, behavioral and cognitive performance." New research by Kaufer and UC Berkeley post-doctoral fellow Elizabeth Kirby has uncovered exactly how acute stress - short-lived, not chronic - primes the brain for improved performance...
Inflammation And Atherosclerosis Hampered By Cell-Permeable Peptide In Mice
Date: Apr-19-2013Atherosclerosis - sometimes called "hardening of the arteries" - is a leading cause of death and morbidity in Western countries. A cell-permeable peptide containing the NF-ĸB nuclear localization sequence (NLS) shows promise as a potential agent in controlling the development of atherosclerotic disease. This study is published in the May 2013 issue of The American Journal of Pathology. Atherosclerosis is a chronic inflammatory disease of the arterial and vascular wall...
