Pulmonary rehabilitation effective for both obese and slim COPD patients
Obese patients with chronic obstructive pulmonary disease (COPD) stand to gain as much from pulmonary rehabilitation as their slimmer counterparts, even though as a group they have a lower exercise capacity, according to new research from the University Hospitals of Leicester in the UK.

A more active lifestyle crucial for day-to-day function in COPD patients
There is no magic bullet to help patients with COPD improve their ability to function in daily life.

Children with severe asthma at increased risk of developing COPD
Children with severe asthma have more than 30 times the risk of developing adult chronic obstructive lung disease (COPD) as adults compared to children without asthma, according to a prospective longitudinal cohort study from the Royal Children's Hospital in Melbourne.

False positives in TB diagnosis lead to real negatives for HIV patients
HIV-infected patients who are falsely diagnosed as having tuberculosis have higher rates of mortality than those who are correctly diagnosed with the disease, according to a study conducted by researchers at University of California -- San Francisco and Makerere University-Kampala.

Estrogen may reduce airway constriction in women patients with asthma
Female sex hormones may work with beta-agonists in reducing airway constriction, according to new bench research from the Mayo Clinic.

Statins decrease risk of clot-related diseases
Individuals at risk for clot-related diseases may benefit from taking common cholesterol-lowering drugs known as statins, according to a study conducted by researchers at the University of Connecticut.

High-fat meals a no-no for asthma patients
People with asthma may be well-advised to avoid heavy, high-fat meals, according to new research.

Resilience factor low in depression, protects mice from stress
Scientists have discovered a mechanism that helps to explain resilience to stress, vulnerability to depression and how antidepressants work.

Long-term use of vitamin E may decrease COPD risk
Long-term, regular use of vitamin E in women 45 years of age and older may help decrease the risk of chronic obstructive pulmonary disease (COPD) by about 10 percent in both smokers and nonsmokers, according to a study conducted by researchers at Cornell University and Brigham and Women's Hospital.

New technique may quickly distinguish between active and latent TB
An emerging technique designed to quickly distinguish between people with active and dormant tuberculosis may help health professionals diagnose the disease sooner, thereby potentially limiting early exposure to the disease, according to a study conducted by researchers at Duke University Medical Center.

A new possible treatment to treat P. aeruginosa in cystic fibrosis (CF) patients appears to be promising, according to research to be presented at the ATS 2010 International Conference in New Orleans.

Internet monitoring strategy for severe asthma patients shown to be effective
Patients with severe asthma who use an Internet-supported strategy and daily monitoring of exhaled nitric oxide were able to control their asthma with lower overall dosing of oral corticosteroids than patients who underwent usual care, according to research from the Netherlands.

Higher oxygen levels improve preterm survival, increase risk for eye condition
Two findings from an NIH research network study provide new information on how much oxygen very preterm infants should receive starting at birth and the most effective means to deliver it to them.

Higher blood pressure found in people living in urban areas
People who live in urban areas where particulate air pollution is high tend to have higher blood pressure than those who live in less polluted areas, according to researchers from the University of Dusiburg-Essen in Germany.

Control of cell movement with light accomplished in living organisms
A technique developed in the laboratory of Klaus Hahn, Ph.D., the Thurman Professor of Pharmacology at the University of North Carolina at Chapel Hill and a member of UNC Lineberger Comprehensive Cancer Center, uses light to manipulate the activity of a protein at precise times and places within a living cell, providing a new tool for scientists who study the fundamentals of protein function.
