(Press-News.org) MINNEAPOLIS – Contrary to a widely accepted belief, African-Americans may have a higher rather than lower risk of developing multiple sclerosis (MS) than Caucasians, according to a new study in the May 7, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
"Our population-based study is the first of its kind to look at this question. The belief (that African- Americans have a lower risk of developing MS) was based on evidence that was problematic," said study author Annette Langer-Gould, MD, with Kaiser Permanente Southern California Department of Research & Evaluation in Pasadena, Calif., and a member of the American Academy of Neurology.
For the study, researchers examined the entire database of more than 3.5 million members of the Kaiser Permanente Southern California health plan over a three-year period and identified 496 people with newly diagnosed MS. This type of study, which is termed population-based, is considered a more accurate way to determine disease risk than to examine only those people who attend a specific clinic or hospital.
The study found that African-Americans had a 47 percent increased risk of MS compared with Caucasians, while Hispanics and Asians had a 58 and 80 percent lower risk than Caucasians.
Sex differences in MS risk were also highlighted in the study. The higher risk in African-Americans was found in women only whereas the lower risk for Hispanics and Asians was found in both sexes. African-American women had triple the risk of MS compared to African-American men.
African-Americans made up 21 percent of those with MS, while they made up only 10 percent of the total study population. Caucasians made up 52 percent of those with MS, compared to 38 percent of the total population. A total of 23 percent of those with MS were Hispanic, compared to 40 percent of the total population. Asians made up 3 percent of those with MS, compared to 9 percent of the population.
"One explanation for our findings is that people with darker skin tones have lower vitamin D levels and ultimately, an increased risk, but this would not explain why Hispanics and Asians have a lower risk than Caucasians," said Langer-Gould. "About 19,000 people per year, or 250 people per week, will be diagnosed with MS in the US alone. These numbers highlight the need for more minorities to be included in MS studies, so that we can fully understand how race may play a role in developing the disease."

Minneapolis, MN, May 6, 2013 – Adults with end-stage respiratory failure and pulmonary hypertension requiring ECMO (extracorporeal membrane oxygenation) have been "bridged" toward lung transplantation with novel lung assist devices such as the Novalung. This and related devices work based on pumpless application of oxygenators. A presentation by David M. Hoganson, MD, and colleagues from Washington University School of Medicine in St. Louis at the Congenital Heart Disease Session of the 93rd AATS Annual Meeting describes the first time application of this technology to ...
PASADENA, Calif., May 6, 2013 – Multiple sclerosis is more common in black women than in white women, according to a Kaiser Permanente study published today in the journal Neurology. The findings run contrary to the widely accepted belief that blacks are less susceptible to MS, according to the researchers.
Researchers examined the electronic health records of more than 3.5 million members of Kaiser Permanente Southern California between January 2008 and December 2011 and identified 496 people newly diagnosed with MS. Of these diagnosed cases, black patients had a 47 ...
Boston, Mass. –A quality improvement platform developed at Boston Children's Hospital could help health care provider groups continuously improve their medical practice, curbing costs and improving patient outcomes. Successful outcomes associated with the platform, called Standardized Clinical Assessment and Management Plans (SCAMPs) and supported by a consortium of Massachusetts payers, are featured in the May issue of Health Affairs.
SCAMPs start with existing practice recommendations, but are continuously revised as clinicians learn from everyday patient encounters. ...
Research from King's College London reveals the detailed mechanism behind how stress hormones reduce the number of new brain cells - a process considered to be linked to depression. The researchers identified a key protein responsible for the long-term detrimental effect of stress on cells, and importantly, successfully used a drug compound to block this effect, offering a potential new avenue for drug discovery.
The study, published in Proceedings of the National Academy of Sciences (PNAS) was co-funded by the National Institute for Health Research Biomedical Research ...
Around 150 million people globally are chronically infected with the hepatitis C virus (HCV) – a major cause of liver disease and the fastest growing cause of liver transplantation and liver cancer. 1 New prevention strategies are urgently required as people are continuing to be infected with HCV. Findings, published in Hepatology, reveal the impact of a new antiviral treatment that could potentially reduce HCV rates in some cities affected by chronic HCV prevalence by half over 15 years.
In Europe, the US and other developed countries the majority of HCV infections ...
Some of the earliest results from The Environmental Determinants of Diabetes in The Young (TEDDY) study - a major Europe-USA consortium exploring the causes of type 1 diabetes in children – has found no evidence for viral infection as a cause of the rapid-onset form of the condition.

NEW YORK, NY (May 6, 2013) – A team of New York Stem Cell Foundation (NYSCF) Research Institute scientists report today the generation of patient-specific bone substitutes from skin cells for repair of large bone defects. The study, led by Darja Marolt, PhD, a NYSCF-Helmsley Investigator and Giuseppe Maria de Peppo, PhD, a NYSCF Research Fellow, and published in the Proceedings of the National Academy of Sciences of the USA, represents a major advance in personalized reconstructive treatments for patients with bone defects resulting from disease or trauma.
This advance ...
New York, NY, May 6, 2013—Combining Medicare's hospital, physician, and prescription drug coverage with commonly purchased private supplemental coverage into one health plan could produce national savings of $180 billion over a decade while improving care for beneficiaries, according to a new study by researchers at The Johns Hopkins Bloomberg School of Public Health and The Commonwealth Fund published today in the May edition of Health Affairs. Under the proposed plan, called "Medicare Essential," Medicare beneficiaries could save a total of $63 billion between 2014 and ...
