Smoking ban reduces emergency room admissions
Workplace smoking bans are gaining ground globally, and one study has shown that they may have significant health effects. The study, conducted by researchers in Dublin, found that emergency room admissions due to respiratory illness dropped significantly in Ireland after the implementation of a workplace smoking ban, compared to admissions that took place before the ban went into effect.

New class of asthma, COPD drugs identified
Researchers in Baltimore have identified new compounds which relax airway muscles and may provide relief from shortness of breath for patients with COPD and asthma.

Gene expression changes in nasal cells may help identify lung cancer
A simple, minimally-invasive technique using cells from the interior of the nose could help clinicians detect lung cancer in its earliest - and most treatable - stages, according to a study conducted by researchers in Boston.

New GM-SCF therapy to defeating flu shows promise
New research on mice has shown that pulmonary administration of granulocyte macrophage-colony stimulating factor (GM-CSF) significantly reduces flu symptoms and prevents death after a lethal dose influenza virus.

Vitamin D deficiency reduces lung growth and lung function
Vitamin D deficiency is linked to deficits in lung function and altered lung structure. Examinations of specific tissue responses revealed model mice had reduced lung function.

High self-reported asthma rates in Chinatown, NY
Research conducted seven years after the terrorist attacks on the World Trade Center (WTC) in New York City (NYC) found that children attending the socioeconomically and ethnically homogeneous elementary school closest to Ground Zero have high rates of self-reported asthma and airway obstruction.

Sleep aid increases CPAP adherence in sleep apnea patients
New research suggests that patients newly diagnosed with obstructive sleep apnea (OSA) who use a short-course of the sleep aid, eszopiclone, when beginning continuous positive airway pressure (CPAP) therapy, are more adherent with therapy in six months.

Sleep may be factor in weight control, BMI
Body mass index (BMI) is linked to length and quality of sleep in a surprisingly consistent fashion, revealed by researchers on Sunday, May 17, at the American Thoracic Society's 105th International Conference in San Diego.

Vitamin D levels linked to asthma severity
Serum levels of vitamin D in more than 600 Costa Rican children were inversely linked to several indicators of allergy and asthma severity, including hospitalizations for asthma, use of inhaled steroids and total IgE levels.

Losing weight can cure obstructive sleep apnea in overweight
Losing weight is perhaps the single most effective way to reduce obstructive sleep apnea OSA symptoms and associated disorders in sufferers of obstructive sleep apnea (OSA).

Food additives linked to lung cancer risk
New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.

Childhood wheezing with rhinovirus can increase asthma risk
Infants who experience viral respiratory illnesses with wheezing are known to be at increased risk for developing asthma later during childhood. It is not known, however, whether every type of respiratory virus that produces wheezing presents similar risk.

Boys grow out of childhood asthma
Boys may be more apt than girls to have childhood asthma, but, when compared to girls, they are also more likely to grow out of it in adolescence and have a decreased incidence of asthma in the post-pubertal years. This indicates that there may be a buried mechanism in asthma development, according to a prospective study that analyzed airway responsiveness (AR) in more than 1,000 children with mild to moderate asthma over a period of about nine years.

First-born babies' have higher asthma and allergy rates
First-born children are at higher risk of developing asthma and allergy because of different conditions they experience in the uterus, revealed by researchers.
