Background: In two pivotal phase 3 trials, up to 24 weeks of treatment with elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) was efficacious and safe in patients with cystic fibrosis (CF) ≥12 years of age who have at least one allele. The aim of this study is to assess long-term safety and efficacy of ELX/TEZ/IVA in these patients.

Methods: In this phase 3, open-label, single-arm extension study, participants with -minimal function (from a 24-week parent study; n=399) or - (from a 4-week parent study; n=107) genotypes receive ELX/TEZ/IVA at the same dose (ELX 200 mg once daily, TEZ 100 mg once daily and IVA 150 mg every 12 h).

Interventions to promote adherence to long-term oxygen therapy (LTOT) in chronic obstructive pulmonary disease (COPD) are needed. To examine the real-world effectiveness of phone-based peer coaching on LTOT adherence and other outcomes in a pragmatic trial of patients with COPD. In a hybrid effectiveness/implementation pragmatic trial, patients were randomized to receive phone-based proactive coaching (educational materials, five phone-based peer coaching sessions over 60 d), reactive coaching (educational materials, peer coaching when requested), or usual care.

Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) was shown to be safe and efficacious in people with cystic fibrosis (CF) heterozygous for F508del and a minimal function mutation (F/MF) or homozygous for F508del (F/F) in two pivotal Phase 3 trials, significantly improving percentage predicted forced expiratory volume in 1 second, Cystic Fibrosis Questionnaire-Revised, Respiratory Domain (CFQ-R RD) scores, and sweat chloride concentration. Here, we analyzed the 11 non-respiratory domains (non-RDs) of the CFQ-R, which assess general health-related quality of life (i.e.

Background: Elexacaftor-tezacaftor-ivacaftor is a small-molecule cystic fibrosis transmembrane conductance regulator (CFTR) modulator regimen shown to be efficacious in patients with at least one allele, which indicates that this combination can modulate a single allele. In patients whose other allele contains a gating or residual function mutation that is already effectively treated with previous CFTR modulators (ivacaftor or tezacaftor-ivacaftor), the potential for additional benefit from restoring Phe508del CFTR protein function is unclear.

Methods: We conducted a phase 3, double-blind, randomized, active-controlled trial involving patients 12 years of age or older with cystic fibrosis and -gating or -residual function genotypes.

Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Assessment, Development and Evaluation approach was used to formulate clinical recommendations.

Background: The majority of prescriptions for supplemental oxygen are written when patients are discharged to home from the hospital and the evaluation of these patients is inconsistent. Respiratory Therapists receive training in the evaluation and management of patients needing oxygen. The primary goal of the study was to estimate the frequency with which respiratory therapists (RTs) evaluate the need for home oxygen in patients hospitalized for COPD exacerbations before discharge.

Just over 100 years ago, John Scott Haldane published a seminal report about the therapeutic potential of supplemental oxygen to treat hypoxemia. In the 1980s, a pair of clinical trials confirmed the benefit of long-term oxygen therapy in improving survival in patients with COPD associated with severe resting hypoxemia. This review provides a summary of evidence supporting long-term and short-term oxygen therapy, as well as the various types of oxygen equipment commonly used in homes to deliver supplemental oxygen.

Background: Low physical activity in patients with chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality. To inform the design of a home-based physical activity promotion program for patients with COPD recently discharged from a minority-serving hospital, we conducted a cohort study to evaluate objectively measured daily physical activity and patient-reported outcomes.

Methods: This was a 12-week prospective cohort study of patients with a physician diagnosis of COPD recently hospitalized (≤ 12 weeks) for respiratory symptoms.

Previous work indicates the potential for community health workers and peer coaches serving as patient navigators to improve processes of care and health outcomes during care transitions, but have not been sufficiently tested to determine if such programs improve measures of patient experience in minority serving institutions. The objectives of the Patient Navigator to Reduce Readmissions (PArTNER) study was to: 1) conduct a pragmatic clinical effectiveness trial comparing a multi-faceted, stakeholder-supported Navigator intervention (in-person CHW visits in the hospital and after hospital discharge, plus telephone-based peer coaching) versus usual care on the experience of hospital-to-home care transitions in patients hospitalized with heart failure, pneumonia, chronic obstructive pulmonary disease, myocardial infarction, or sickle cell disease; 2) examine the effectiveness of the Navigator intervention in patient subgroups; and 3) understand the barriers and facilitators of successfully implementing the Navigator intervention across patient populations. The co-primary outcomes are the 30-day changes in: 1) Patient Reported Outcomes Measurement Information System (PROMIS) emotional distress-anxiety, and 2) PROMIS informational support.

Splenosis is an acquired ectopic autotransplantation of splenic tissue; that occurs after traumatic splenic rupture and splenectomy [1]. Splenosis is a rare but benign disease, and the diagnosis can be challenging as the multiple incidentally found nodules could mimic malignancy [2]. Abdominopelvic Splenosis is thought to occur in as many as 65% of cases of splenic rupture [1].

Limited socioeconomic resources contribute to high readmission rates at minority serving institutions (MSIs). A better understanding of patient-level factors and need for patient navigators could inform approaches to enhance care transitions tailored to these vulnerable patient populations. We sought to understand the perspectives of patients and their caregivers about hospital to home transitions from an MSI, as well as their attitudes about patient navigators to facilitate care transitions.
