Radiation for prostate cancer linked to secondary cancers, study finds

Radiation for prostate cancer linked to secondary cancers, study finds

Among men treated for prostate cancer, those who received radiation therapy were more likely to develop bladder or rectal cancer, according to a new study from the University of Michigan Comprehensive Cancer Center. “Overall the incidence of these cancers is low Continue reading

Tool to better screen, treat aneurysm patients

Tool to better screen, treat aneurysm patients

New research by an international consortium, including a researcher from Lawrence Livermore National Laboratory, may help physicians better understand the chronological development of a brain aneurysm. Using radiocarbon dating to date samples of ruptured and unruptured cerebral aneurysm (CA) tissue, the team, led by neurosurgeon Nima Etminan, found that the main structural constituent and protein — collagen type I — in cerebral aneurysms is distinctly younger than once thought Continue reading

How breast cancer ‘expresses itself’

How breast cancer ‘expresses itself’

About one in eight women in the United States will contract breast cancer in her lifetime. Now new research from Tel Aviv University-affiliated researchers, in collaboration with Johns Hopkins University, has provided another tool to help women, clinicians, and scientists searching for a cure to the one of the most widespread yet incurable diseases on the planet.

Major geographic disparities in access to kidney transplantation

Major geographic disparities in access to kidney transplantation

There is substantial geographic variation in access to kidney transplantation among the more than 4000 US dialysis facilities that treat patients with kidney failure, with a disproportionate lack of access to those in the Southeast. Certain factors, which are described in several papers published in the American Journal of Transplantation , seem to explain these differences, and they underscore the need for political, financial, and health systems changes to reduce transplant inequities across the country Continue reading

How long should HCV treatment last? Study suggests answers are complex

How long should HCV treatment last? Study suggests answers are complex

As new treatments for hepatitis C virus (HCV) are approved, biomedical scientists are exploring their mechanisms and what they reveal about the virus. An online publication this month in Hepatology is the first to report real-time tracking of viral decay in the liver and blood in 15 patients with HCV Continue reading

Uncovering Clues to the Genetic Cause of Schizophrenia

Uncovering Clues to the Genetic Cause of Schizophrenia

The overall number and nature of mutations — rather than the presence of any single mutation — influences an individual’s risk of developing schizophrenia, as well as its severity, according to a discovery by Columbia University Medical Center researchers published in the latest issue of Neuron . The findings could have important implications for the early detection and treatment of schizophrenia. Maria Karayiorgou, MD, professor of psychiatry and Joseph Gogos, MD, PhD, professor of physiology and cellular biophysics and of neuroscience, and their team sequenced the “exome” — the region of the human genome that codes for proteins — of 231 schizophrenia patients and their unaffected parents Continue reading

Dialysis patients’ anxiety, depression linked to physical impairments

Dialysis patients’ anxiety, depression linked to physical impairments

With the rate of chronic kidney disease on the rise among older Americans, researchers seeking to improve patients’ quality of life studied a group of adults undergoing hemodialysis and found their higher rates of depression and anxiety could be associated with their impaired physical exercise capability and reduced daily physical activity, according a new study published online by the Journal of Renal Nutrition . The researchers studied 72 relatively healthy maintenance hemodialysis patients and compared them to 39 healthy adults who were not on dialysis. They found significantly higher rates of anxiety and depression among the dialysis patients, than among the adults who were not on dialysis. Continue reading

Implications of mandatory flu vaccinations for health-care workers

Implications of mandatory flu vaccinations for health-care workers

Employers planning to implement mandatory influenza vaccination policies for health care workers need to understand the implications, according to an analysis published in CMAJ ( Canadian Medical Association Journal ). Vaccination rates among health care workers are less than 50%, well below the level necessary for herd immunity. Evidence indicates that vaccination of health care workers can benefit patient health, leading to a move by many to consider mandatory influenza vaccination as a condition of employment or to require employees to wear a mask during influenza season.
