Objective: The use of pretransplant extracorporeal membrane oxygenation (ECMO) continues to increase. In the most recent Scientific Registry for Transplant Recipients, 11% of listed candidates for lung transplantation were on ECMO. We evaluated the impact of the duration of ECMO bridge to transplantation on posttransplant outcomes using United Network for Organ Sharing data.

Purpose: To evaluate the feasibility and acceptability of Capnography-Assisted Learned Monitored (CALM) Breathing, a carbon dioxide (CO 2 ) biofeedback, and motivational interviewing intervention, to treat dyspnea and anxiety together.
Methods: We randomized adults (n = 42) with chronic obstructive pulmonary disease (COPD) to a 4-week, 8-session intervention (CALM Breathing, n = 20) or usual care (n = 22). The CALM Breathing intervention consisted of tailored, slow nasal breathing exercises, capnography biofeedback, motivational interviewing, and a home breathing exercise program.

Objectives: Single lung transplant (SLT) is an acceptable treatment modality for certain patients with end-stage lung disease. SLT occurs when two appropriate donor lungs are split between recipients ('split singles') or when one donor lung is adequate for transplant and the other lung is declined ('isolated single'). There is a paucity of literature investigating the outcomes in patients who received an isolated SLT.

Nontuberculous mycobacteria (NTM) are prevalent among patients with bronchiectasis. However, the long-term natural history of patients with NTM and bronchiectasis is not well described. To assess the impact of NTM on 5-year clinical outcomes and mortality in patients with bronchiectasis.
View Article and Find Full Text PDFBackground: Although dyspnea is a primary symptom of chronic obstructive pulmonary disease (COPD), its treatment is suboptimal. In both COPD and acute anxiety, breathing patterns become dysregulated, contributing to abnormal CO, dyspnea, and inefficient recovery from breathing challenges. While pulmonary rehabilitation (PR) improves dyspnea, only 1-2% of patients access it.

Background: Blood group O candidates have lower lung transplantation rates despite having the most common blood group. We postulated that waitlist outcomes among these candidates and those with other blood types vary with disease severity and lung allocation score (LAS).
Methods: We performed a retrospective cohort study of 32,772 waitlist candidates using the United Network of Organ Sharing registry from May 2005 to 2020.
Unlabelled: Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disorder characterized by oculocutaneous albinism, platelet storage defect with resultant bleeding diathesis, and pulmonary fibrosis. The bleeding diathesis associated with HPS had long been considered a contraindication to lung transplantation; consequently, few reports of successful lung transplantation for HPS exist.
Methods: In the largest case series on lung transplant for HPS, we describe the characteristics of 11 lung transplant candidates with HPS-related pulmonary fibrosis, and the management and outcomes of 7 patients who underwent lung transplantation.

Rationale: Non-cystic fibrosis bronchiectasis (NCFB) is characterized by dilated bronchi, poor mucus clearance and susceptibility to bacterial infection. Pseudomonas aeruginosa (PA) is one of the most frequently isolated pathogens in patients with NCFB. The purpose of this study was to evaluate the association between presence of PA and disease severity in patients within the US Bronchiectasis and Nontuberculous mycobacteria (NTM) Research Registry (BRR).

Background: Increasing numbers of patients are being diagnosed with bronchiectasis, yet much remains to be elucidated about this heterogeneous patient population. We sought to determine the relationship between nutrition and health outcomes in non-cystic fibrosis (non-CF) bronchiectasis, using data from the U.S.
View Article and Find Full Text PDFBackground: In patients with bronchiectasis, airway clearance techniques (ACTs) are important management strategies.
Research Question: What are the differences in patients with bronchiectasis and a productive cough who used ACTs and those who did not? What was the assessment of bronchiectasis exacerbation frequency and change in pulmonary function at 1-year follow up?
Study Design And Methods: Adult patients with bronchiectasis and a productive cough in the United States Bronchiectasis and NTM Research Registry were included in the analyses. ACTs included the use of instrumental devices and manual techniques.

Objective: This study compares and contrasts the clinical features of non-cystic fibrosis bronchiectasis with 3 uncommon disorders known to be associated with bronchiectasis but with distinctly different underlying defined pathophysiologic derangements, namely severe alpha-1 antitrypsin deficiency (AATD), common variable immunodeficiency (CVI) and primary ciliary dyskinesia (PCD).
Methods: The Bronchiectasis Research Registry provides a central database for studying patients with non-cystic fibrosis bronchiectasis. This report consists of information from 13 U.
Rationale: Staphylococcus aureus is commonly cultured from the sputum of patients with bronchiectasis; however, little is known about the prevalence of the organism in these patients, the characteristics of patients who have grown the organism, or its implications.
Objectives: Determine the relationship between S. aureus and pulmonary function, frequency of exacerbations, and frequency of hospitalization in patients with bronchiectasis Methods: The Bronchiectasis Research Registry is a database of adults with non-cystic fibrosis bronchiectasis identified from 13 sites within the United States.

Background: Non-cystic fibrosis bronchiectasis ("bronchiectasis") is a chronic inflammatory lung disease often associated with nontuberculous mycobacteria (NTM) infection. Very little data exist to guide bronchiectasis management decisions. We sought to describe patterns of inhaled corticosteroid (ICS) and antibiotic therapy in the United States.

Background: Environmental exposures to indoor allergens are major contributors to asthma symptoms, particularly in inner cities. The effectiveness of household allergen reduction as an adjunct to National Asthma Education Prevention Program guideline-based pharmacologic therapy in asthma has not been prospectively studied.
Objective: To study the effect of individualized allergen reduction on ability to reduce asthma pharmacologic therapy over 40 weeks.
Background: The National Emphysema Treatment Trial (NETT) proved that lung volume reduction surgery (LVRS) was safe and effective in patients with certain clinical characteristics and using defined inclusion-exclusion criteria. Based on the selection criteria developed in that trial, we performed bilateral LVRS on 49 patients during the period of February 2004 until May 2009.
Methods: Forty-nine patients underwent lung volume reduction by either median sternotomy (10) or video-assisted thoracoscopic surgery (39) selected according to NETT described parameters.

Objectives: We hypothesized that lung-volume reduction surgery for pulmonary emphysema would improve body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index, a multidimensional predictor of survival in chronic obstructive pulmonary disease. We also aimed to identify preoperative predictors of improvement in the BODE index.
Methods: In a prospective cohort study of patients undergoing lung-volume reduction surgery at our center, with the methodology of the National Emphysema Treatment Trial, we compared clinical characteristics before and 1 year after surgery with the Wilcoxon signed rank test.
