Abnormal Brain Pathology Likely Culprit For Family History Of Alzheimer's Disease
Date: Apr-19-2013Close family members of people with Alzheimer's disease are more than twice as likely as those without a family history to develop silent buildup of brain plaques associated with Alzheimer's disease, according to researchers at Duke Medicine. The study, published online in the journal PLOS ONE confirms earlier findings on a known genetic variation that increases one's risk for Alzheimer's, and raises new questions about other genetic factors involved in the disease that have yet to be identified...
Research On Rat Brains Has Implications For Understanding Memory And Imagination
Date: Apr-19-2013While studying rats' ability to navigate familiar territory, Johns Hopkins scientists found that one particular brain structure uses remembered spatial information to imagine routes the rats then follow. Their discovery has implications for understanding why damage to that structure, called the hippocampus, disrupts specific types of memory and learning in people with Alzheimer's disease and age-related cognitive decline...
Interventions To Physicians And Patients Improve Osteoporosis Treatment At Low Cost
Date: Apr-19-2013Reminding primary care doctors to test at-risk patients for osteoporosis can prevent fractures and reduce health care costs, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Osteoporosis is a condition that is common, costly and undertreated. Low trauma fractures in older individuals are a "red flag" for osteoporosis, but those at risk often are not treated for the condition. Rates of osteoporosis testing and treatment are typically less than 20 percent in the first year after a fracture...
Zoledronic, A Common Osteoporosis Drug Slows Formation Of New Bone
Date: Apr-19-2013Although the drug zoledronic acid slows bone loss in osteoporosis patients, it also boosts levels of a biomarker that stops bone formation, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Osteoporosis weakens bones and increases the risk patients will suffer fractures. The findings suggest combination therapy may be a more effective approach to battling this common condition...
Media Coverage Of Aggression In Ice Hockey Has Shifted From Violence To Safety Rules, Equipment
Date: Apr-19-2013Popular media perspectives on traumatic brain injuries (TBI) in sports like ice hockey has changed over time and may influence people's attitudes towards these injuries, according to research published in the open access journal PLOS ONE by Michael Cusimano and colleagues from St. Michael's Hospital, Toronto, Canada. The authors compared articles published in the Chicago Tribune, New York Times, Toronto Star and Vancouver Sun from 1998-2000 and 2009-2011...
No Doctor, No Matter How Senior They Are, Can Be Untouchable
Date: Apr-19-2013Even very senior doctors should be subject to the same codes of conduct argues whistleblower No doctor, no matter how senior they are, can be untouchable, argues Dr Peter Wilmshurst in this week's BMJ. Even very senior doctors "should be subject to the same codes of conduct, and to the same sanctions when they are breached," he says...
Radiation Dose Reduced For Abdominal CT
Date: Apr-19-2013Radiation dose reduction has moved to the forefront of importance in medical imaging with new techniques being developed in an effort to bring doses down as low as possible. What difference can these techniques make? Researchers at Indiana University School of Medicine aimed to find out. "We conducted a study to quantify dose reduction, comparing two years' worth of data and 11,458 abdomen and pelvic CT exams," said Dr. Jonas Rydberg, lead author of the study...
Size Of Lesions Seen On Chest CT Images Affected By Radiation Dose Level
Date: Apr-19-2013The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. The study, conducted at Massachusetts General Hospital in Boston, used a 3D image processing tool to quantitatively measure the volume of the lymph nodes and lung nodules...
The Immense And Growing Burden Of Osteoporosis Across Europe
Date: Apr-19-2013A new report prepared in collaboration with the International Osteoporosis Foundation (IOF) and the European Federation of Pharmaceutical Industry Associations, is the first to describe in detail the epidemiology, burden, and treatment of osteoporosis in all 27 member states of the European Union (EU27)...
Inequalities In Osteoporosis Care In The Europe Union Revealed By New Scorecard
Date: Apr-19-2013A panel of international experts working in cooperation with the International Osteoporosis Foundation (IOF) have published SCOPE - or Scorecard for Osteoporosis in Europe. Focusing on key aspects of service provision and uptake, the Scorecard compares how the 27 different countries within the European Union (EU) care for people with osteoporosis to reduce their risk of bone fractures. Fractures, which mostly affect older adults, can result in pain, long-term disability and even premature death...
