Children exposed to secondhand smoke are more likely to grow up aggressive, antisocial

Children who are exposed to secondhand smoke in early childhood are more likely to grow up to physically aggressive and antisocial, regardless of whether they were exposed during pregnancy or their parents have a history of being antisocial, according to Linda Pagani and Caroline Fitzpatrick of the University of Montreal and its affiliated CHU Sainte-Justine hospital.

Early adenotonsillectomy can improve behavior and sleep apnea symptoms in children

Adenotonsillectomy, or the removal of the adenoids and tonsils, is performed 500,000 times a year in the United States, often as a treatment for children with obstructive sleep apnea.

Genetic risk factor for pulmonary fibrosis can be used to identify individuals at risk for lung disease

A paper recently published in the New England Journal of Medicine and co-written by physicians and scientists at the University of Colorado School of Medicine finds that an important genetic risk factor for pulmonary fibrosis can be used to identify individuals at risk for this deadly lung disease.

Physical activity: An independent predictor of COPD patients' hospitalizations

Clinical measurement of physical activity appears to be an independent predictor of whether or not patients with chronic obstructive pulmonary disease will end up being hospitalized, according to a new study conducted by researchers in Connecticut.

Vitamin C kills drug-resistant TB bacteria in lab

In a striking, unexpected discovery, researchers at Albert Einstein College of Medicine of Yeshiva University have determined that vitamin C kills drug-resistant tuberculosis bacteria in laboratory culture.

Study: Extended azithromycin therapy may offer significant benefits to COPD patients

Extended use of a common antibiotic may prolong the time between hospitalizations for patients suffering from chronic obstructive pulmonary disease, according to a post-hoc analysis of a multicenter study which compared the hospitalization rates of patients treated with a 12-month course of azithromycin to the rates of those treated with placebo.

Kidneys discarded for transplant can be used for manufacturing replacement organs, say researchers

Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs?

Diachisis can occur during subacute phase of ischemic stroke, find USF researchers

While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports that within a week of a stroke caused by a blood clot in one side of the brain, the opposite side of the brain shows signs of microvascular injury.

Spontaneous brain activity in amygdala higher among combat veterans with PTSD

Chronic trauma can inflict lasting damage to brain regions associated with fear and anxiety. Previous imaging studies of people with post-traumatic stress disorder, or PTSD, have shown that these brain regions can over-or under-react in response to stressful tasks, such as recalling a traumatic event or reacting to a photo of a threatening face.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

Simvastatin hinders positive effects of exercise for obese adults, say researchers

Statins, the most widely prescribed drugs worldwide, are often suggested to lower cholesterol and prevent heart disease in individuals with obesity, diabetes and metabolic syndrome, which is a combination of medical disorders including excess body fat and/or high levels of blood pressure, blood sugar and/or cholesterol.

Research shows new neural circuits arise when hippocampus is disabled

When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways - often far from the damaged site.

Study reveals that prolonged Dkk1 signaling can lead to fibrosis, stiffening of artery walls

The hardening of arteries is a hallmark of atherosclerosis, an often deadly disease in which plaques, excessive connective tissue, and other changes build up inside vessel walls and squeeze off the flow of oxygen-rich blood throughout the body.

Research sheds new light on occupation-specific rehabilitation

After cardiac surgery, should a farmer and an attorney take the same physical test to be found fit for work? They do now. But new research from Jenny Adams, PhD, at Baylor Health Care System's Baylor Hamilton Heart and Vascular Hospital, could change that.

Scientists develop eco-friendly flame retardants with dual effects

Amid concerns over the potential health effects of existing flame retardants for home furniture, fabrics and other material, scientists are reporting development of an "exceptionally" effective new retardant that appears safer and more environmentally friendly.

Spending for veterans' care delayed

Bloomberg reports that the U.S. Department of Veterans Affairs has put off more than $765 million in spending authorized for equipment and care. Meanwhile, the Los Angeles Times reports on how securing disability compensation has become a battle for many Vietnam Veterans.

Research on total anomalous pulmonary venous connection

Total anomalous pulmonary venous connection, one type of "blue baby" syndrome, is a potentially deadly congenital disorder that occurs when pulmonary veins don't connect normally to the left atrium of the heart.

Nutritional supplement may improve survival rates of babies born with heart defects

A common nutritional supplement may be part of the magic in improving the survival rates of babies born with heart defects, researchers report. Carnitine, a compound that helps transport fat inside the cell powerhouse where it can be used for energy production, is currently used for purposes ranging from weight loss to chest pain.

Researchers discover novel mechanism of tumor hypoxia

An article published recently in Tumor Microenvironment and Therapy - an open access journal by Versita, defines a novel mechanism of tumor hypoxia induced by the longitudinal gradient of residual oxygen along tumor vessels as they transverse the tumor.

Ochsner Medical Center performs Gulf South Region's first implant of SynCardia Total Artificial Heart

When Alfred Williams was admitted to Ochsner Medical Center in December, the 41-year-old father of five had exhausted all treatment options for his enlarged heart. His condition, known as dilated cardiomyopathy, had progressed to end-stage heart failure affecting both sides of his heart. Unable to walk, he had been confined to a bed for months. Hospice care seemed like the only option Mr. Williams had left… until doctors approached him about becoming Ochsner's first patient to receive the SynCardia temporary Total Artificial Heart.
