Annual FEV1 Loss in Patients with Noncystic Fibrosis Bronchiectasis and Affecting Factors

Objectives: Bronchiectasis is a chronic respiratory disease characterized by sputum production, cough, and several bronchial infections. Lung function is an important parameter to evaluate and study in patients with bronchiectasis. This study aimed to evaluate the annual changes in forced expiratory volume in one second (FEV1) and related factors in...

CME Article: Clinical Outcomes of Noninvasive Ventilation in Asthma, Bronchiectasis, and Other COPD

Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality and disability worldwide. Use of noninvasive ventilation (NIV) appears to be associated with a significant decrease in frequency of exacerbation, hospital admissions, and mortality in patients with COPD. In this study, we sought to determine clinical outcomes, prevalence,...

Association between Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers and Lung Cancer

Objectives: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are the most commonly prescribed antihypertensives, with prior studies identifying a possible association between long-term use and increased rates of lung cancer. This study evaluated this potential association in a large population using propensity matching. Methods: This was a population-based...

Outcomes of Idiopathic Pulmonary Fibrosis Improve with Obesity: A Rural Appalachian Experience

Objectives: Obesity can be an independent predictor of fibrosis in tissues, including the liver, heart, and skin. We evaluated a rural Appalachian cohort of idiopathic pulmonary fibrosis (IPF) for its relation to obesity. Methods: Using American Thoracic Society 2018 diagnostic guidelines, an IPF cohort was systematically identified at an Appalachian...

OPEN: Immune Checkpoint Inhibitor-Related Pulmonary Toxicity: Focus on Nivolumab

The development of checkpoint inhibitors has changed the treatment paradigm for cancer. Checkpoint inhibitors nivolumab, pembrolizumab, and cemiplimab target programmed death-1 (PD-1), whereas durvalumab, avelumab, and atezolizumab target PD-ligand 1. Ipilimumab targets cytotoxic T lymphocyte–associated antigen 4. Used as monotherapy or in combination, these inhibitors have shown remarkable efficacy in...

Prevalence and Clinical Impact of Atrial Fibrillation in Patients with Pulmonary Embolism

Objectives: Atrial fibrillation (AF) has been suggested as a cause for pulmonary embolism (PE). We aimed to explore the prevalence and clinical impact of AF in patients with PE.Methods: Using the 2012–2014 National (Nationwide) Inpatient Sample database, we identified “adult patients with PE” as the principal discharge diagnosis. The identified...
