Smoking and obesity linked to hearing loss

One of the largest studies into the risk factors for age-related hearing loss has found that smoking and body mass index (BMI) are two of the main culprits whereas alcohol has a protective effect, but high levels of work noise remain the biggest risk.

Oxygen-rich lifesaving efforts pose risk for respiratory infections

Each year, thousands of premature infants battle to breathe. Thanks to life-saving interventions developed in the past couple decades - steroids given to their mothers to stall pre-term labor, mechanical ventilation, air enriched with extra oxygen, and surfactant, a crucial wetting agent that makes breathing less work - most of these newborns survive with enough lung function to grow and go home.

Why some treatments rescue aging skin

Fine wrinkles, deeper creases, saggy areas around the mouth and neck - the sights in the mirror that make baby boomers wince - are not inevitable. They result from a structural breakdown inside the skin that some existing treatments effectively counteract by stimulating the growth of new, youthful collagen, University of Michigan scientists say.

Avoiding spleen removal for Cooley's anemia sufferers

Researchers from Weill Cornell Medical College may have discovered the precise role of a gene in one of the world's most common blood disorders, beta-thalassemia, commonly known as Cooley's anemia. Along with sickle-cell anemia, Cooley's anemia is the most commonly inherited disease in the world, affecting many people of Mediterranean descent, and 20 out of every 100,000 African-Americans. The World Health Organization estimates that between 50,000-100,000 children are born with the disease each year.

Flavanols in cocoa improve artery function, help relieve stress on heart

For people with diabetes, sipping a mug of steaming, flavorful cocoa may seem a guilty pleasure. But new research suggests that indulging a craving for cocoa can actually help blood vessels to function better and might soon be considered part of a healthy diet for the prevention of cardiovascular disease.

The emerging role of infection in Alzheimer’s

A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer's disease.

New blood test reveals risk for metabolic syndrome

University of Minnesota researchers have discovered that people with high oxidation levels of the low-density lipoprotein (LDL) particle that carries cholesterol throughout the blood are much more likely to develop metabolic syndrome - which can lead to a considerably increased risk of developing heart disease.

Noninvasive ventilation eases final hours, days for lung cancer patients

For patients with end-stage lung cancer, noninvasive ventilation (NIV) may be more effective at reducing breathing difficulty than standard oxygen therapy, and has the added advantage of reducing patients' reliance on morphine, thus improving lucidity in their final days, according to research presented at the American Thoracic Society's 2008 International Conference in Toronto on Tuesday, May 20.
