Mayo Clinic study using structural MRI may help accurately diagnose dementia patients
A new Mayo Clinic study may help physicians differentially diagnose three common neurodegenerative disorders in the future. The study will be presented at the Alzheimer's Association International Conference on Alzheimer's Disease on July 11 in Vienna.
Easy strength training exercise may help treat tennis elbow, study shows
People with pain in the elbow or forearm from playing sports or just from common everyday activities, might be able to use a simple bar and strengthening exercise to alleviate pain, say researchers who are presenting their study results at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Keystone, Colorado, July 9th-12th. more
Environmental manganese good in trace amounts but can correlate to cancer rates
In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level. more
New oral agents may prevent injury after radiation exposure
Researchers from Boston University School of Medicine (BUSM) and collaborators have discovered and analyzed several new compounds, collectively called the ''EUK-400 series,'' which could someday be used to prevent radiation-induced injuries to kidneys, lungs, skin, intestinal tract and brains of radiological terrorism victims. The findings, which appear in the June issue of the Journal of Biological Inorganic Chemistry, describe new agents which can be given orally in pill form, which would more expedient in an emergency situation. more
Racial disparities in breast cancer mortality are not driven by estrogen receptor status alone
Black women who are diagnosed with breast cancer have a higher probability of dying from the disease than white women, regardless of their estrogen receptor status, according to research from the National Cancer Institute (NCI), part of the National Institutes of Health. Differences in breast cancer mortality may reflect racial differences in access and response to innovative breast cancer treatments, as well as other biological and non-biological factors, according to the report. In addition, the researchers found that differences in outcomes in the first few years post-diagnosis make up nearly all of the disparity. These results were published online June 22, 2009 in the Journal of the National Cancer Institute.
Time to hepatitis C infection in injection drug users lengthening in developed countries
Hepatitis C (HCV), a blood-borne infection that can cause liver damage and death, is very common among injection drug users (IDUs) and is transmitted mainly by the sharing of drug preparation or injection equipment. Researchers funded by NIDA have found that the time from onset of injection drug use to HCV infection for IDUs in developed countries has lengthened since 1995. The researchers analyzed 72 studies of HCV infection in IDUs published between 1989 and 2006. In addition, the researchers compared studies from developed countries (such as the United States) with studies from developing countries. more
HIV prevalence at the United States–Mexico border may change the HIV Epidemic in Mexico
The rapidly changing HIV subepidemic at the border of the United States and Mexico, likely caused by population mobility and the drug and sex trades, may be rapidly affecting the overall HIV epidemic in Mexico. In a recent editorial, NIDA-funded researchers discussed studies of HIV infection at the United States–Mexico border in an effort to better understand factors shaping individual and network-level risks for acquiring HIV. Two different studies in the Mexican border cities of Tijuana and Ciudad Juarez showed a high prevalence of HIV infection among sex workers who were also injection drug users: 6 percent and 12 percent, respectively. more
