How bariatric surgery impacts health depends on type of surgery, patient characteristics
Date: Oct-16-2013The impact of bariatric surgery on risk factors for cardiovascular disease depends on a variety of factors, including the type of surgery, sex of the patient, ethnic background, and pre-surgery body mass index, according to a Kaiser Permanente study published in Annals of Surgery. Researchers examined the electronic health records of more than 4,000 Kaiser Permanente patients in Southern California who had bariatric surgery for weight loss between 2009 and 2011 to determine what factors led to remission - or reduction - of metabolic syndrome after surgery...
Atherosclerosis treatment could be improved by inhibiting a single protein
Date: Oct-16-2013Researchers of the Spanish research council (Consejo Superior de Investigaciones CientÃficas, CSIC) and the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered that inhibiting the protein Rcan1 in mice reduces the burden of atherosclerosis, one of the commonest cardiovascular diseases. The results of their study, published in the prestigious journal EMBO Molecular Medicine, suggest that Rcan1 is a potential target for future drug treatments for this disease, and the team is already working to develop this potential...
Community-based weight loss intervention yields greater weight loss than self-help approach
Date: Oct-16-2013A new randomized controlled trial conducted by Baylor College of Medicine researchers and published as an Article in Press in The American Journal of Medicine finds that overweight and obese adults following a community-based weight loss intervention, namely Weight Watchers, lost significantly more weight than those who tried to lose weight on their own (10.1 lbs. vs. 1.3 lbs. at six months)...
Why aerobic capacity decreases with age
Date: Oct-16-2013Researchers at the University of Colorado have new insight into the age-old question of why maximum heart rate (maxHR) decreases with age. This decrease in maxHR not only limits the performance of aging athletes but it is also a leading cause for nursing home admittance for otherwise-healthy elderly individuals who no longer have the physical capacity required for independent living. We say we're just getting old and slowing down, but exactly what is it that is slowing down? Everybody knows that aerobic capacity decreases with age...
Study of young apes provides valuable information about humans and society
Date: Oct-16-2013Researchers studying young bonobos in an African sanctuary have discovered striking similarities between the emotional development of the bonobos and that of children, suggesting these great apes regulate their emotions in a human-like way. This is important to human evolutionary history because it shows the socio-emotional framework commonly applied to children works equally well for apes. Using this framework, researchers can test predictions of great ape behavior and, as in the case of this study, confirm humans and apes share many aspects of emotional functioning...
Barriers to HPV vaccination
Date: Oct-16-2013A new study explores why girls in minority groups and low-income families, who are most at risk for cervical cancer, may not be getting the human papillomavirus or HPV vaccine. Researchers from the University of Colorado School of Medicine and Children's Hospital Colorado interviewed 41 low-income parents of girls ages 12-15 to determine why they didn't get the vaccine or finish the course, and included both English speakers and Spanish speakers in the study...
Novel fruit fly research offers lessons about traumatic brain injury
Date: Oct-16-2013Faced with news of suicides and brain damage in former professional football players, geneticist Barry Ganetzky bemoaned the lack of model systems for studying the insidious and often delayed consequences linked to head injuries. Then he remembered an unexplored observation from nearly 40 years ago: a sharp strike to a vial of fruit flies left them temporarily stunned, only to recover a short time later. At the time he had marked it only as a curiosity...
The American Heart Association recommends that doctors routinely evaluate patients' physical activity habits
Date: Oct-16-2013Doctors should evaluate your physical activity habits as routinely as checking your blood pressure and other risk factors for cardiovascular diseases, the American Heart Association recommends in a scientific statement published in its journal Circulation. "Most healthcare providers have not routinely assessed physical activity levels among their patients because they have not had the right tools," said Scott Strath, Ph.D., lead author of the statement and associate professor in the Department of Kinesiology at the University of Wisconsin-Milwaukee's College of Health Sciences...
Shielding body from lethal radiation doses using compound derived from vegetables
Date: Oct-16-2013Georgetown University Medical Center researchers say a compound derived from cruciferous vegetable such as cabbage, cauliflower and broccoli protected rats and mice from lethal doses of radiation. Their study, published in the Proceedings of the National Academy of Sciences (PNAS) suggests the compound, already shown to be safe for humans, may protect normal tissues during radiation therapy for cancer treatment and prevent or mitigate sickness caused by radiation exposure. The compound, known as DIM (3,3'-diindolylmethane), previously has been found to have cancer preventive properties...
Survey details the changing nature of work and aging in America
Date: Oct-16-2013The Associated Press-NORC Center for Public Affairs Research has released the results of a major new survey exploring the views of older Americans about their plans for work and retirement. It provides in-depth information about a rapidly growing segment of the population that by choice or circumstance is working longer. The Great Recession has had a marked impact on retirement plans. "The survey illuminates an important shift in Americans' attitudes toward work, aging, and retirement," said Trevor Tompson, director of the AP-NORC Center...
