Quality Of Life For Men With Prostate Cancer Preserved By Proton Therapy Treatment
Date: Oct-31-2012Two studies led by The University of Texas MD Anderson Cancer Center have found that proton therapy preserves the quality of life, specifically urinary and bowel function, in men treated with this targeted radiation modality for prostate cancer. Both studies, led by Andrew K. Lee, M.D., M.P.H., associate professor in MD Anderson's Department of Radiation Oncology, were presented in a poster session at the 54th Annual Meeting of the American Society for Radiation Oncology (ASTRO)...
Study Offers Potential To Slow Neuron Breakdown In Patients With Neurodegenerative Diseases
Date: Oct-31-2012A study in The Journal of Cell Biology shows how a transcription factor called STAT3 remains in the axon of nerve cells to help prevent neurodegeneration. The findings could pave the way for future drug therapies to slow nerve damage in patients with neurodegenerative diseases. In Lou Gehrig's Disease (ALS) and other neurodegenerative diseases, nerve cells usually die in stages, with axons deteriorating first and the cells themselves perishing later. Axon degeneration may represent a turning point for patients, after which so much nerve damage has accumulated that treatments won't work...
Peer Pressure Can Be Used To Promote Physical Activity At School
Date: Oct-31-2012Using peer mentors to enhance school-day physical activity in elementary aged students has been given an A+ from Nova Scotia researchers. And the increased physical activity levels got top grades for significantly improving both academic test scores and cardiovascular fitness levels. Funded principally by the Nova Scotia Research Foundation and supported by community partners including the Heart and Stroke Foundation, research by principal investigator Dr...
Bariatric Surgery Prior To Pregnancy Results In Heart Healthier Kids
Date: Oct-31-2012Kids born to moms who have lost a substantial amount of weight after undergoing bariatric surgery have fewer cardiovascular risk factors than their siblings who were born before the weight loss surgery. This is because the metabolic changes and weight loss that occur after the surgery have a positive effect on inflammatory disease-related genes in the offspring, according to a new study presented at the Canadian Cardiovascular Congress, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society...
Despite Socioeconomic Similarities, Ethnic Disparities In Breast Cancer Survival Remain
Date: Oct-31-2012Disparities in survival after breast cancer persisted across racial/ethnic groups even after researchers adjusted for multiple demographics, such as patients' education and the socioeconomic status of the neighborhood in which they lived, according to data presented at the Fifth AACR Conference on The Science of Cancer Health Disparities, held here Oct. 27-30, 2012. "We learned that the effects of neighborhood socioeconomic status differed by racial/ethnic group...
Alzheimer's Research May Benefit From Finding That Primates' Brains Make Visual Maps Using Triangular Grids
Date: Oct-31-2012Primates' brains see the world through triangular grids, according to a new study published online in the journal Nature. Scientists at Yerkes National Primate Research Center, Emory University, have identified grid cells, neurons that fire in repeating triangular patterns as the eyes explore visual scenes, in the brains of rhesus monkeys. The finding has implications for understanding how humans form and remember mental maps of the world, as well as how neurodegenerative diseases such as Alzheimer's erode those abilities...
In Middle-Aged People With Increased Cardiovascular Risk, Cognitive Functions Improved Significantly By High-Intensity Interval Training
Date: Oct-31-2012High-intensity interval training makes middle-aged people not only healthier but smarter, showed a Montreal Heart Institute (MHI) study led by Dr. Anil Nigam of the MHI and University of Montreal, in collaboration with the Montreal Geriatric University Institute. The participants all had a body-mass index (BMI) between 28 and 31 (overweight) in addition to one or more other cardiovascular risk factors. Body-mass index is calculated as a person's weight divided by their height squared (kg/m2) - 25 to 30 is considered overweight, over 30 is obese...
Health Costs For Seniors In Canada Rising Slowly: Points Way To Medicare Solvency
Date: Oct-31-2012A study published in Archives of Internal Medicine finds that per capita Medicare spending on the elderly has grown nearly three times faster in the United States than in Canada since 1980. (Canada's program, which covers all Canadians, not just the elderly, is also called Medicare.) Cost grew more slowly in Canada despite a 1984 law banning co-payments and deductibles. In the first study of its kind, Dr. David U. Himmelstein and Dr...
Researchers Identify Biomarkers Of Behavior, Therapeutic Targets For Adult B-Acute Lymphoblastic Leukemia
Date: Oct-31-2012New insight into the aggressive behavior of certain adult B-acute lymphoblastic leukemias has provided researchers with a potential new prognostic biomarker and a promising new therapeutic target. The research, conducted by Ari Melnick, M.D...
Hospitalizations Dramatically Reduced By Smoke-Free Laws
Date: Oct-31-2012Smoke-free legislation was associated with substantially fewer hospitalizations and deaths from heart and respiratory diseases, according to research in the American Heart Association journal Circulation. Researchers reviewed 45 studies covering 33 smoke-free laws at the local and state levels around the United States and from countries as varied as Uruguay, New Zealand and Germany and found: Comprehensive smoke-free laws were associated with a rapid 15 percent decrease in heart attack hospitalizations and 16 percent decrease in stroke hospitalizations...
