Multicenter Study
COPD Subtypes Are Differentially Associated with Cardiovascular Events and COPD Exacerbations.
The coronary artery calcium score (CACS) and ratio of the pulmonary artery to aorta diameters (PA:A ratio) measured from chest CT scans have been established as predictors of cardiovascular events and COPD exacerbations, respectively. However, little is known about the reciprocal relationship between these predictors and outcomes. Furthermore, the prognostic implications of COPD subtypes on clinical outcomes remain insufficiently characterized. ⋯ Two chest CT scan parameters, CACS and PA:A ratio, hold distinct predictive values for cardiovascular events and COPD exacerbations that are influenced by specific COPD subtypes.

Breathlessness shares aging mechanisms with frailty and sarcopenia. ⋯ These findings suggest that frailty and sarcopenia strongly contribute to breathlessness in community-dwelling older adults. Measuring sarcopenia and frailty in older adults may offer opportunities to prevent age-related breathlessness.

Comparative Study
Differences in Healthcare and Palliative Care Utilization at the End of Life: a Comparison Study Between Lung Cancer, COPD, and IPF.
Patients with lung cancer, idiopathic pulmonary fibrosis (IPF), and COPD have high symptom burden, poor quality of life, and high health care use at the end of life. Although proactive integration of palliative care in lung cancer can improve outcomes, it is unclear whether similar practices have been adopted in COPD and IPF care. ⋯ This study showed that patients with COPD and IPF are less likely to receive outpatient palliative care and opioid prescriptions and are more likely to use end-of-life intensive care than patients with lung cancer. Further research should explore health system barriers contributing to differences in care patterns to optimize quality of life and to align with patient goals of care.

Acute exacerbations (AEs) of COPD are increasingly recognized as episodes of heightened risk of cardiovascular events. It is not known whether exacerbation history is differentially associated with future myocardial infarction (MI) or pulmonary embolism (PE). ⋯ The risk of MI and PE increased with the frequency and severity of AEs of COPD in this large, real-life cohort of patients with COPD.

Older adults surviving critical illness often experience new or worsening functional impairments. Modifiable positive psychological constructs such as resilience may mitigate post-intensive care morbidity. ⋯ ICU survivors with higher resilience had increased rates of survival and functional independence, although the slope of functional decline before vs after the ICU stay did not differ according to resilience group.
