Pulmonary hypertension (PH) is common in elderly patients, but a detailed analysis of the causes of PH in the elderly has not been performed. We hypothesized that pulmonary arterial hypertension (PAH) is rare in elderly patients and sought to describe the characteristics of these patients at a large referral center. ⋯ PAH is an uncommon cause of PH in elderly patients, most frequently associated with connective tissue disease. WHO group 2 PH and mixed disease are common, highlighting a need for careful phenotyping of elderly patients with PH prior to initiating PAH therapy.

Perimenopause is associated with increased cardiovascular risk. OSA is an emerging risk factor for cardiovascular disease, particularly among men, but the independent contribution of OSA to cardiovascular risk in climacteric women is not clear. ⋯ OSA is common, underdiagnosed, and independently associated with high BP and increased arterial stiffness in perimenopausal women.

Observational Study
Functional Impact of a Spectrum of Interstitial Lung Abnormalities in Rheumatoid Arthritis.
Approximately 10% of patients with rheumatoid arthritis (RA) have interstitial lung disease (ILD), and one-third have subclinical ILD on chest CT scan. In this study, we aimed to further characterize functional decrements in a spectrum of RA-associated ILD. ⋯ We have shown that patients with RA have varying degrees of ILAs that are associated with a spectrum of functional and physiologic decrements. Our findings suggest that improved risk stratification and detection of ILAs will provide a therapeutic window that could improve RA-ILD outcomes.

The presence of visible mold in households is associated with asthma. However, the role of "classroom fungus" in the development of childhood asthma, as well as the fungal species that may lead to asthma, remains controversial. This nationwide school survey was conducted to investigate the correlation between fungal spores in classrooms and asthma in schoolchildren. ⋯ Classroom Aspergillus/Penicillium and basidiospores are significantly associated with childhood asthma and ASROH. Government health policy should explore environmental interventions for the elimination of fungal spores in classrooms to reduce the prevalence of childhood asthma.

Measures of physical function, daily physical activity, and exercise capacity have been proposed for the care of patients with COPD but are not used routinely in daily office care. Gait speed is a powerful and simple measure of physical function in elderly patients and seems to be a promising measure for the daily care of patients with COPD. The objective of this study was to comprehensively evaluate the determinants and factors influencing gait speed in COPD, particularly the association of gait speed with objectively measured physical activity and the most used exercise capacity field test in cardiopulmonary disease: the 6-min walk test (6MWT). ⋯ Gait speed is more indicative of exercise capacity (6MWT) than daily physical activity in COPD. Despite its simplicity, gait speed has outstanding screening properties for detecting poor and very poor 6MWT performance, making it a useful and informative tool for the clinical care of patients with COPD.
