Financial struggles plague families of children with autism
COLUMBIA, Mo. - The information that a child has been diagnosed with autism often throws parents into an emotional tailspin. A new study from a University of Missouri researcher says most people don't immediately consider the major financial struggles that follow. She suggests more outreach is needed to help families plan and cope with the profound financial life changes they may face.

Exercise testing may help predict seriousness of mitral regurgitation
NEW YORK (Dec. 11, 2007) -- In as many as one in five people over age 55, when the heart contracts to send blood around the body, some degree of backward leakage occurs across the mitral valve, a condition known as mitral regurgitation (MR). When sufficiently severe, MR causes buildup of blood in the lungs, leading to difficulty in breathing (dyspnea, or shortness of breath), a serious condition called congestive heart failure. MR also can cause heart rhythm irregularities (arrhythmias) such as atrial fibrillation, which can lead to strokes and other problems, and ventricular tachycardia, which can cause sudden death.

Procedure helps to eliminate sleep apnea
(Chicago, IL, October 24, 2007) — A procedure known as uvulopalatopharyngoplasty (UPPP) may help some patients improve or even eliminate their obstructive sleep apnea (OSA), according to a new study. The research, presented at CHEST 2007, the 73rd annual international scientific assembly of the American College of Chest Physicians (ACCP), says the procedure, which removes excess tissue in the throat or mouth to widen the airway, can reduce the amount of treatment required by patients with OSA. In addition, researchers say UPPP also can eliminate OSA completely in some patients.

Sexual function affected by stem cell transplant according to long-term study
WASHINGTON, Sept. 18, 2007 -- A long-term study found that a type of stem cell transplant used for patients with life-threatening diseases, such as leukemia and lymphoma, results in decreased sexual function and activity for recipients. Further, males are likely to recover from these changes over time, while the sexuality of female patients remains compromised. In addition, neither male nor female long-term cancer survivors regained levels of sexual activity and function equal to those of their peers who have not had cancer, according to a Blood First Edition Paper prepublished online today. Blood is the official journal of the American Society of Hematology.

New research discovers independent brain networks control human walking
(Baltimore, MD) - In a study published in the August issue of Nature Neuroscience, researchers at the Kennedy Krieger Institute in Baltimore, Maryland found that there are separate adaptable networks controlling each leg and there are also separate networks controlling leg movements, e.g., forward or backward walking. These findings are contrary to the currently accepted theory that leg movements and adaptations are directed by a single control circuit in the brain. The ability to train the right and left legs independently opens the door to new therapeutic approaches for correcting walking abilities in patients with brain injury (e.g., stroke) and neurological disorders (e.g., cerebral palsy and multiple sclerosis).
