The treatment specifically targeted lung tissue breakdown, airway wall thickening, inflammation and lung over-expansion.
More than 10 years after 9/11, when thousands of rescue and recovery workers descended on the area surrounding the World Trade Center in the wake of the terrorist attacks, a research team led by Benjamin J. Luft, M.D., the Edmund D. Pellegrino Professor of Medicine, and Medical Director of Stony Brook’s World Trade Center Health Program, and Evelyn Bromet, Ph.D., Distinguished Professor, Departments of Psychiatry and Behavioral Science, and Preventive Medicine, Stony Brook University School of Medicine, has published results of a study examining the relationship between the two signature health problems among WTC first responders—respiratory illness and post-traumatic stress disorder (PTSD).
Adding inhaled dry powder mannitol to standard therapy for cystic fibrosis produced sustained improvement in lung function for up to 52 weeks, according to a new study. Along with the treatment’s efficacy and good safety profile, the convenience and ease of administration of mannitol treatment may improve adherence with therapy in these patients.
Inhaled glucocorticoids for the treatment of asthma during pregnancy are not associated with an increased risk of most diseases in offspring, but may be a risk factor for endocrine and metabolic disturbances, according to a new study.

About 80 to 90 percent of children at one time or another experience breathing problems. In her new book, "Take a Deep Breath: Clear the Air for the Health of Your Child" (World Scientific Publishers), scheduled for publication in January 2012, Dr. Nina L. Shapiro, director of pediatric ear, nose and throat at Mattel Children's Hospital UCLA and an associate professor of surgery at the David Geffen School of Medicine at UCLA, explains all the puzzling and oftentimes distressing breathing patterns children have throughout development.
Hypoglossal nerve stimulation (HGNS) produced marked dose-related increases in airflow in obstructive sleep apnea (OSA) patients without arousing them from sleep, according to a new study from the Johns Hopkins Sleep Disorders Center. The study suggests the potential therapeutic efficacy of HGNS across a broad range of sleep apnea severity and offers an alternative to continuous positive airway pressure (CPAP), the current mainstay of treatment for moderate to severe OSA. The effectiveness of CPAP is often limited by poor patient adherence.

Although increased use of noninvasive positive-pressure ventilation (NIPPV) nationwide has helped decrease mortality rates among patients hospitalized with chronic obstructive pulmonary disease (COPD), a small group of patients requiring subsequent treatment with invasive mechanical ventilation (IMV) have a significantly higher risk of death than those placed directly on IMV, according to researchers in the United States who studied patterns of NIPPV use
Corticosteroids do not improve survival nor alter the progression of COPD and may reduce lung symptoms as little as 20 percent.

The drug, which is normally prescribed in patients with acute heart failure,increases the sensitivity of muscle tissue to calcium, improving the muscle’sability to contract.
Technique for observing how proteins work in human tissue from cystic fibrosis patients yields new insights into the cellular processes of disease.
