Background: Patients requiring lung transplant for cystic fibrosis (CF) may require retransplant due to limited graft survival and otherwise excellent life expectancy. Optimal transplant strategy for this population, including single vs double lung retransplant, has not been established.
Methods: We performed a retrospective analysis of the United Network for Organ Sharing/Organ Procurement and Transplant Network (UNOS/OPTN) database to identify adult lung retransplant recipients from 2005 to 2021 with a primary diagnosis of CF.
Objective: The purpose of this study was to investigate the technical feasibility of integrating the quantitative maps available from SyntheticMR into the head and neck adaptive radiation oncology workflow. While SyntheticMR has been investigated for diagnostic applications, no studies have investigated its feasibility and potential for MR-Simulation or MR-Linac workflow. Demonstrating the feasibility of using this technique will facilitate rapid quantitative biomarker extraction which can be leveraged to guide adaptive radiation therapy decision making.

This report summarizes CF community SRH research priorities and workshop discussions/future study planning.
Methods: Pre-workshop, we distributed a community prioritization survey on CF SRH research/care.
Pulmonary exacerbations (PEx) remain the most common cause of morbidity, recurrent hospitalization, and diminished survival in people with cystic fibrosis (PWCF) and are characterized by excess inflammation. Corticosteroids are potent, widely available antiinflammatory drugs. However, corticosteroid efficacy data from randomized controlled trials in PWCF are limited.

Methods: We surveyed multidisciplinary clinicians exploring attitudes, practices, and preferences toward male CF SRH care.
Background: Most males with cystic fibrosis (mwCF) are infertile but with CF transmembrane conductance regulator (CFTR) modulator-conferred benefits, more are utilizing assisted reproductive technologies (ART). Administration of normal human doses of modulators in animal reproductive models caused no genotoxicity; no human data exists. Potential health decline following modulator discontinuation makes the decision to withhold therapy during reproduction challenging.

We evaluated the occurrence of such respiratory compromise events in French bulldogs presented to two referral hospitals.
Methods: Clinical data for French bulldogs diagnosed with IVDE were retrospectively collated, including severity of neurological deficits, neuroanatomical localisation, diagnosis, details of respiratory compromise, treatment and outcome.
Introduction: Lymphoscintigraphy (LS) helps identify drainage to interval (epitrochlear or popliteal) lymph node basins for extremity melanomas. This study evaluated how often routine LS evaluation identified an interval sentinel lymph node (SLN) and how often that node was found to have metastasis.
Methods: A single institution, retrospective study identified patients with an extremity melanoma who underwent routine LS and SLN biopsy over a 25-y period.
Previous studies indicate that hospital rather than home treatment of pulmonary exacerbations (PEx) in people with cystic fibrosis (CF) can improve outcomes. We evaluated characteristics of adult participants from the Standardized Treatment of Pulmonary Exacerbations (STOP2) trial with two separate comparisons: (1) those who were treated initially in hospital (N = 768) to those treated initially at home (N = 214) and (2) those treated only in hospital (N = 328) to those who were treated only at home or both at home and in hospital (N = 654). Participants who had Medicaid insurance, were treated for shorter duration, and traveled longer to reach treatment centers were more likely to have been treated initially in the hospital.

Substitution of tyrosine with phenylalanine residues (Y-F) in the capsid have been shown to protect the AAV vector from ubiquitin/proteasome degradation, increasing transduction efficiency. We tested the mutant Y733F-AAV8 vector for mucus diffusion, as well as the safety and efficacy of pigment epithelium-derived factor (PEDF) gene transfer to the lung.

The INCREASE study looked at how well a medication called inhaled treprostinil works and how safe it is, compared to placebo (a fake medication), in adults who have pulmonary hypertension associated with interstitial lung disease or PH-ILD.
What Were The Results?: A total of 326 participants took part in the study.
Background: Pulmonary exacerbations (PEx) remain a major cause of morbidity and mortality in people with cystic fibrosis (PWCF). Although the combination cystic fibrosis transmembrane conductance regulator (CFTR) modulators lumacaftor/ivacaftor and tezacaftor/ivacaftor have been shown to reduce PEx frequency, their influence on clinical and biochemical responses to acute PEx treatment is unknown.
Methods: We performed a secondary analysis of STOP2, a large multicenter randomized controlled trial of antimicrobial treatment durations for adult PWCF presenting with PEx.
Adeno-associated virus (AAV) vector has shown multiple clinical breakthroughs, but its clinical implementation in inhaled gene therapy remains elusive due to difficulty in transducing lung airway cells. We demonstrate here AAV serotype 6 (AAV6) associated with extracellular vesicles (EVs) and secreted from vector-producing HEK-293 cells during vector preparation (EVAAV6) as a safe and highly efficacious gene delivery platform for inhaled gene therapy applications. Specifically, we discovered that EVAAV6 provided markedly enhanced reporter transgene expression in mucus-covered air-liquid interface (ALI) cultures of primary human bronchial and nasal epithelial cells as well as in mouse lung airways compared to standard preparations of AAV6 alone.

Introduction: Following availability of the highly effective cystic fibrosis (CF) transmembrane conductance regulator modulator, elexacaftor/tezacaftor/ivacaftor, there was a near doubling of pregnancies reported in the United States (US) in people with CF. We sought to determine health impacts of planned (PP) versus unplanned pregnancies (UP).
Methods: We collected retrospective pregnancy data from January 2010-December 2020 from 11 US CF centers.
Background: Peripherally inserted central catheters (PICCs) are used commonly to administer antibiotics to people with cystic fibrosis (CF), but their use can be complicated by venous thrombosis and catheter occlusion.
Research Question: Which participant-, catheter-, and catheter management-level attributes are associated with increased risk of complications of PICCs among people with CF?
Study Design And Methods: This was a prospective observational study of adults and children with CF who received PICCs at 10 CF care centers in the United States. The primary end point was defined as occlusion of the catheter resulting in unplanned removal, symptomatic venous thrombosis in the extremity containing the catheter, or both.
