Multicenter Study
Trajectories and prognostic significance of 6-minute walk test parameters in fibrotic interstitial lung disease: A multi-center study.
Functional capacity, as measured by the 6-min walk test (6MWT), is often reduced in fibrotic interstitial lung disease (ILD). This study evaluated longitudinal changes and the prognostic significance of 6MWT parameters, and explored change in oxygenation status as a physiological criterion to define disease progression in patients with fibrotic ILD. ⋯ Patients with IPF/PPF and non-IPF/PPF have comparable deterioration in functional capacity. Oxygenation status provides prognostic information in PPF and may assist in defining disease progression in fibrotic ILD.

There is now ample evidence that differences in sex and gender contribute to the incidence, susceptibility, presentation, diagnosis, and clinical course of many lung diseases. Some conditions are more prevalent in women, such as pulmonary arterial hypertension and sarcoidosis. Some life stages-such as pregnancy-are unique to women and can affect the onset and course of lung disease. ⋯ This article is the second part of a state-of-the-art review of specific effects of sex and gender focused on epidemiology, disease presentation, risk factors, and management of selected lung diseases. We review the more recent literature and focus on guidelines incorporating sex and gender differences in pulmonary hypertension, CF and non-CF bronchiectasis, sarcoidosis, restless legs syndrome and insomnia, and critical illness. We also provide a summary of the effects of pregnancy on lung diseases and discuss the impact of sex and gender on tobacco use and treatment of nicotine use disorder.

Clinical Trial
Sleep arousal-related ventricular repolarisation lability is associated with cardiovascular mortality in older community-dwelling men.
Sleep is fragmented by brief arousals, and excessive arousal burden has been linked to increased cardiovascular (CV) risk, but mechanisms are poorly understood. ⋯ gov.

A 66-year-old woman with a medical history of seronegative rheumatoid arthritis on long-standing methotrexate and adalimumab therapy was referred to the pulmonary clinic for abnormal chest imaging. The patient was also under evaluation by rheumatology physicians for increased fatigue, nonproductive cough, and recurrent sinus infections. At the time of the initial pulmonary visit, the patient complained of acute onset of bilateral blurry vision and subsequently was diagnosed with anterior uveitis and received ophthalmic steroids with significant improvement. ⋯ Over the course of 4 months, the patient experienced worsening dyspnea with exertion. She was a lifelong nonsmoker and had no history of recent travel. However, on review of possible environmental exposures, patient stated using feather pillows and bedding for several decades.
