Surrogates are divided on how much guidance they want from doctors when making end-of-life medical choices for critically ill patients. While a slight majority prefer doctor's advice, many feel burdened by guilt and value patient's values over physician input.
Patients who underwent lung reduction surgery showed a significant survival benefit compared to medical treatment, with an average time until a 'composite event' of two years. The procedure also improved quality of life for at least five years post-operative period, especially in patients with upper-lobe-predominant emphysema.
Researchers found that even at low ozone concentrations, healthy individuals can experience significant decreases in lung function after moderate exercise. The study suggests that healthier individuals may exhibit individual variability in their responses to ozone, with some showing strong sensitivity while others are less affected.

Researchers found that calcitriol, a form of vitamin D, reduced growth-factor-induced airway smooth muscle proliferation in cells isolated from both asthmatic and non-asthmatic individuals. This process, called airway remodeling, leads to reduced lung function over time if left untreated.
A study found that mice treated with the algae-derived protein Griffithsin had a 100% survival rate after exposure to the SARS coronavirus, whereas untreated mice only survived 30%. The protein alters sugar molecules on the virus's envelope, preventing it from causing disease.
Research found high self-reported asthma rates in NYC children living near Ground Zero, with 50% increase in new cases following the 2001 attacks. Exposure to urban ambient pollution and toxins released by the WTC plume may contribute to the persistently high asthma incidence.

Treated mice had a significant survival advantage, decreased lung bacterial burden, and spread compared to control mice. The once-daily dosing regimen increased compliance, offering a potential means to improve patient outcomes.

Research found black Americans are nearly twice as likely to develop acute lung injury compared to white Americans, with a higher burden of immune-compromising conditions and greater severity of illness at admission. Despite this, in-hospital mortality rates among patients with ALI did not vary meaningfully by race.
A new study found that flu vaccines are no more effective in preventing hospitalizations in children with asthma than in those without the condition. The research suggests that vaccination may actually increase the risk of hospitalization among asthmatic children.
A new study found that patients with diabetes and retinopathy have a strong association with obstructive sleep apnea, suggesting a link between the two conditions. The researchers recommend that doctors and nurses consider screening for OSA in type 2 diabetes patients with retinopathy.
Research reveals patients with undiagnosed sleep apnea are more susceptible to the negative effects of sleep deprivation and moderate alcohol consumption on driving performance. OSA patients performed poorly on steering tasks and were more likely to crash compared to healthy individuals after sleep restriction or alcohol exposure.
Researchers found that non-smokers who reported childhood exposure to ETS were more likely to have CT patterns indicating early emphysema. Childhood ETS exposure may be associated with detectable differences in lung structure and early emphysema later in life, even among non-smokers.
New estimates suggest latent TB infection screening should focus on high-risk populations, rather than the entire general population. Targeted screening efforts can effectively control tuberculosis, according to a study by Massachusetts General Hospital researchers.
A recent study found that children of mothers who smoked during pregnancy and early childhood years are at a higher risk of taking up smoking as teens and young adults. The researchers also discovered that offspring of mothers who smoked during this critical period were less likely to quit smoking in adulthood.
A new study suggests that women may be more vulnerable to the harmful effects of smoking due to smaller airways and gender differences in metabolism. The research analyzed data from a Norwegian case-control study, including 954 subjects with chronic obstructive pulmonary disease (COPD) and 955 controls.
Researchers found that 79% of patients treated with bronchial thermoplasty experienced a statistically significant and clinically meaningful improvement in their quality-of-life measurements.

The system used a combination of voice messages and branching logic to address barriers to compliance, resulting in significant public health benefits.
Researchers found that a self-treatment program for COPD patients led to fewer exacerbation days and increased medication use. This resulted in cost savings due to reduced hospitalizations and healthcare contacts. The study suggested that implementing such programs could help manage COPD effectively.
A recent study suggests that exercises can improve symptoms of mild to moderate obstructive sleep apnea (OSA) by promoting remodeling of the upper airways. After three months, patients in the exercise group showed significant improvements in oxygen saturation levels, snoring symptoms, and quality of sleep scores.
Research suggests a link between vitamin D insufficiency and increased asthma severity in children, including hospitalizations, airway reactivity, and use of inhaled steroids. Vitamin D levels were inversely linked to several indicators of allergy and asthma severity.
Researchers found that cigarette smoke exposure alters the immune response to bacteria in mice, leading to increased inflammation and weight loss. This shift in inflammatory markers may impact treatment efficacy with corticosteroids for COPD patients.
Researchers found specific gene variations affect lung function growth and susceptibility to environmental insults. Variants in GST genes correlated with poorer lung function and greater susceptibility to damage from maternal cigarette smoke during pregnancy.
Patients with moderate to severe COPD show altered breathing and swallowing coordination even during normal eating. The study found that COPD patients swallow more often at the end of exhalation, a pattern that disrupts safe swallowing.
A recent study has found a strong association between high waist circumference and decreased lung function. The research, analyzing over 120,000 participants, revealed that abdominal obesity is independently associated with impaired lung function, even when accounting for other factors such as smoking history and body mass index.
