In contrast, soy oil supplements showed a marginal, nonsignificant protective effect against the negative impact of particulate matter on heart rate variability.
A long-term study found that individuals with moderate to severe sleep-disordered breathing have a significantly increased odds of suffering a stroke over the next four years. The study analyzed data from 1,475 participants and revealed that 21 people suffered their first-ever stroke at an average age of 53.
A study found significant relationships between household endotoxin levels and diagnosed asthma, recent symptoms, and wheezing. The strongest effects were observed in adults, with lower levels of endotoxins in bedding compared to kitchen floor dust.

Researchers found that wheezing prevalence follows distinct patterns by age 6 and stability of lung function is maintained through school years. Children with early wheeze tend to have lower lung function levels but stable rates.
A new study identifies genetic susceptibility as a significant risk factor for pulmonary fibrosis. The condition, which can be triggered by smoking and other factors, causes inflammation and scarring in the lungs. Researchers also explored a more accurate blood test to detect latent tuberculosis infection.
A new study found that Californians exposed to low levels of naturally occurring asbestos are at higher risk for malignant mesothelioma. The research analyzed 2,908 cases over 10 years and found that people living close to asbestos source rocks had a greater chance of developing the disease, despite lower occupational exposure.

Researchers discovered that low doses of azithromycin can halt and reverse lung function decline in the majority of lung transplant patients with BOS, offering a new hope for treatment.
Children with asthma are at significantly greater risk for serious airway constriction if their fathers have a history of the disease. A 5-year study found paternal asthma strongly associated with childhood airway hyperresponsiveness, a defining feature of asthma. In contrast, maternal asthma showed no correlation.

A study of young adults found a strong association between asthma and panic disorder, with active asthma predicting subsequent panic disorder. The 'electronic nose' technology also showed promise in detecting lung cancer by analyzing exhaled breath samples.
A study by the American Thoracic Society found that measuring hormone levels can reduce antibiotic use in pneumonia patients. The study showed that patients with low procalcitonin levels were not given antibiotics and recovered similarly to those who received a full course of antibiotics.
A study analyzing US lung transplant data between 1994 and 2002 found that female recipients experienced a 60% increased risk of primary graft dysfunction compared to male recipients. This condition can lead to severe lung injury, high mortality rates, prolonged hospital stays, and other serious complications.
A study of 235 patients with asthma found that laughter-induced asthma (LIA) is a common condition, affecting 56% of patients. Patients with LIA reported longer periods of well-controlled asthma during which they could laugh without experiencing symptoms, suggesting that LIA may indicate poorly controlled asthma.

The program aims to complement physician care and improve asthma management for patients with geographic barriers.
A national population-based study of 16,036 lung cancer patients found that Hispanics with curable stage I lung cancer had poorer lung cancer specific survival rates and worse all-cause mortality than white persons. This disparity was largely explained by lower surgical resection rates among Hispanics and a higher probability of being ...
Research suggests that daily acetaminophen use is associated with a higher prevalence of asthma and chronic obstructive pulmonary disease (COPD), as well as decreased lung function. In contrast, vitamin C supplementation during pregnancy can limit the negative effects of nicotine on fetal lung tissue.
A study found that family conferences in ICUs missed opportunities to discuss withholding or withdrawing life-sustaining therapy due to clinicians' failure to listen and respond appropriately. The missed opportunities fell into three categories: listening, acknowledging emotions, and addressing medical ethics principles.
A study of 752 French patients found that shorter graft ischemic times were associated with improved long-term survival after single or double lung transplantation. The median ischemic time was 240 minutes, and a cutoff time of 330 minutes was identified as best discriminating between survivors and non-survivors.
