Washington, Nov 11: Sleeping less than seven and a half hours per day can raise your chances of developing a heart disease, according to a new study.

The study has been published in the November 10 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

In addition, a combination of little sleep and overnight-elevated blood pressure appears to be associated with an increased risk of the disease.

Washington, Nov 11 : A new study has found that babies placed in incubators after birth are less likely to have depression as adults.

An international team of researchers has found that infants who receive incubator care after birth are two to three times less likely to suffer from depression.

"In mammals, separation between mother and child after birth has always been considered a major stressor that can cause behavioural problems well into adulthood," said coauthor Richard E. Tremblay a professor of psychology, pediatrics and psychiatry at the Université de Montréal and director of the Research Unit on Children''s Psycho-Social Maladjustment at the Sainte Justine Hospital Research Center.

Washington, Nov 11: Researchers from Emory University School of Medicine suggest that analysing daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes often occur during early morning hours.

According to Dr Ibhar Al Mheid, a postdoctoral cardiology researcher at Emory, endothelial cells serve as the interface between the blood and the arteries, controlling arterial tone and helping to prevent clots that lead to strokes and heart attacks.

The researchers sought to determine the circadian pattern of both endothelial function -- the ability of blood vessels to relax -- and the abundance of the progenitor cells.

Washington, Nov 10 : Access to appropriate care, patient adherence, distrust of the medical profession, delayed asthma diagnosis, culture, lifestyle choices and genetic discrepancies, are some of the barriers in managing asthma, according to experts.

Allergists detailed factors that act as barriers in asthma care at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Seattle.

Washington, Nov 10 : A new study by Mayo Clinic researchers has suggested that obstructive sleep apnea (OSA) - and, in particular, the low nighttime oxygen saturation of the blood it causes - may be a risk factor for sudden cardiac death (SCD).

OSA is a condition that disrupts breathing during sleep and is associated with obesity. The new study identified OSA as one of two traits that increase the risk of SCD. The other is age - patients who are 60 years old or older.

Washington, Nov 10 : Chronic use of the asthma drug corticosteroid may have some serious impact on bones, according to a study presented at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Seattle.

The results came after an analysis of large population databases by researchers led by Dr. Rebecca Green, assistant professor, paediatric endocrinology and diabetes, Washington University School of Medicine in St. Louis.
