Blacks with muscular dystrophy die 10-12 years younger than whites: New study

Widening mortality gap likely caused by inequities in care, insurance coverage

2010-09-13
(Press-News.org) African Americans with muscular dystrophy die 10 to 12 years younger than their white counterparts, according to research published in the Sept. 14 issue of Neurology, the medical journal of the American Academy of Neurology.

The black-white mortality gap, which was calculated on the basis of 20 years of data, is among the largest ever observed in the annals of research into racial disparities in health care, say Dr. Nicte Mejia and Dr. Rachel Nardin, co-authors of the editorial. "Furthermore," they write, "white patients with MD [muscular dystrophy] enjoy increasing survival, while survival of black patients with MD barely budges," leading to an ongoing widening of that gap.

Muscular dystrophy is a group of inherited muscle diseases that lead to early death due to respiratory or cardiac failure. Various types of MD affect about 50,000 Americans.

"Inequities in the health delivery system – and the multiple ways in which race constrains access to care – seem the most likely explanation for the observed MD black-white mortality gap," Mejia and Nardin write in their editorial. But they add that inadequate access to care due to lack of good quality health insurance may also be part of the picture.

"Nonelderly African Americans are 1.5 times more likely than whites to lack any type of insurance and about twice as likely to rely on Medicaid," they write, noting that lack of health insurance is linked to lack of access to care.

And while Medicaid, the public health program for the poor, compares favorably with private insurance in providing access to primary care, it falls short when it comes to providing access to the standard-of-care treatments needed to manage conditions like muscular dystrophy, they say.

These shortcomings of Medicaid coverage are "particularly worrisome because more than half of the new health coverage under the 2010 National Health Reform will be Medicaid."

In a separate comment made today, Nardin said, "Replacing the current U.S. health care financing system with a single-payer system that would ensure comprehensive insurance coverage for every American, regardless of race, would go a long way toward reducing this type of disparity."

INFORMATION: Mejia and Nardin's editorial, titled "Dying young: Eliminating racial disparities in neuromuscular disease outcomes," is based on a research paper by Aileen Kenneson, Ph.D., Ajay Vatave, M.D., and Richard Finkel, M.D., titled "Widening Gap in age at muscular dystrophy-associated death between black and whites, 1986-2005," which is being published simultaneously in the same issue of Neurology, the world's leading clinical neurology journal.

Smokeless tobacco products not a safe option, won't help smokers quit

2010-09-13
Smokeless tobacco products should not be used as an alternative to cigarettes or for smoking cessation due to the risk of addiction and return to smoking, according to an American Heart Association policy statement. Smokeless tobacco products such as dry and moist snuff as well as chewing tobacco may also increase the risk of fatal heart attack, fatal stroke and certain cancers, according to the statement published online in Circulation: Journal of the American Heart Association. "No tobacco product is safe to consume," said Mariann Piano, Ph.D., lead writer of the ...

Signaling hope for polycystic kidney disease

2010-09-13
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common genetic disease that results in chronic kidney failure. Although the genes responsible for ADPKD have been identified (PKD1, PKD2), relatively little is known about how mutations in these genes promote cyst growth molecularly. In this paper, scientists at Children's Hospital in Boston, lead by Jordon Kreidberg, investigated the signaling pathways that go awry in the disease using mouse kidney epithelial cells in which Pkd1 was genetically deleted. They found that the protein c-Met was hyperactive in Pkd1-deficient ...

'Hi-JAK-ing' cancer by inhibiting Jak2

2010-09-13
Myeloproliferative neoplasms (MPN) comprise a family of blood cancers characterized by clonal expansion of a single blood cell type. Untreated, these cancers can progress to bone marrow failure and acute myeloid leukemia. Several groups have identified activating mutations in the JAK2 gene as associated with MPN; JAK2 inhibition has therefore emerged as approach to MPN therapy. Thus far, however, JAK2 inhibition strategies have had limited efficacy and have been accompanied by significant toxicity. In this paper, Ross Levine and his group at the Memorial Sloane Kettering ...

Exosomal release of beta-catenin may explain why CD82 and CD9 suppress tumor metastasis

Exosomal release of beta-catenin may explain why CD82 and CD9 suppress tumor metastasis
2010-09-13
Researchers reveal a new way in which cells restrain beta-catenin and potentially suppress tumor metastasis: the protein can be ejected from cells in small vesicles called exosomes. The study appears online on September 13 in the Journal of Cell Biology (www.jcb.org). Beta-catenin is a central component of the Wnt signaling pathway that controls cell proliferation and differentiation. Activation of the Wnt pathway stabilizes beta-catenin, allowing it to move into the cell nucleus and control the expression of many different genes. Michael Caplan's group at Yale University ...

Enlarged hearts in women shrink faster than those in men after aortic valve replacement

2010-09-13
Heart enlargement caused by narrowed aortic valves regresses faster in elderly women than in men after aortic valve replacement, according to research reported in a surgical supplement of Circulation: Journal of the American Heart Association. Men's slower heart-size regression times may be attributable to genetic differences that cause the heart to develop more fibrous tissue after surgery because of narrowed heart valves, a condition known as aortic stenosis. "We show for the first time that elderly women and men differ in their gene expression related to fibrous ...

New metabolic markers may predict preeclampsia in early pregnancy

2010-09-13
An international team of scientists and physicians used a combination of sophisticated emerging technologies and data analysis to detect 14 simple metabolites with high accuracy to predict in early pregnancy which women are at risk of developing preeclampsia in later pregnancy, according to a study reported in Hypertension: Journal of the American Heart Association. Currently there is no predictive test for the condition and no cure other than delivery of the baby. Preeclampsia is a life-threatening condition characterized by high blood pressure and high levels of protein ...

Available physician characteristics may not help patients find high-quality care

2010-09-13
Publicly available information about board certification, education and malpractice claims appear to provide consumers with little information about the quality of care individual physicians provide, according to a report in the September 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. "To improve the quality of care received by their beneficiaries, some health plans use physician report cards and tiered physician networks to steer their members toward physicians who provide high-quality care. However, most patients do not have access to ...

Diet/exercise intervention for patients at risk for heart disease improves quality of life

2010-09-13
A lifestyle intervention incorporating exercise training and diet counseling in primary health care settings appears to improve quality of life among adults at moderate to high risk for heart disease and appears cost-effective compared to standard care, according to a report in the September 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Most individuals in developed countries do not reach recommended levels of physical activity, and are thus at higher risk of illness and death, according to background information in the article. "Extensive ...

Protein-based biomarkers in blood serum could classify individuals with Alzheimer's disease

2010-09-13
An initial analysis suggests that biomarkers in blood serum can be combined with clinical information to accurately classify patients with Alzheimer's disease, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals. "There is clearly a need for reliable and valid diagnostic and prognostic biomarkers of Alzheimer's disease, and in recent years, there has been an explosive increase of effort aimed at identifying such markers," the authors write as background information in the article. "It has been previously argued that, ...
