Purpose Of Review: Cystic fibrosis is a genetic disease that increases risk of death from respiratory failure because of impairment in mucociliary clearance. Complex daily care regimens including medications and airway clearance techniques (ACTs) aim to preserve lung function and alleviate symptoms for people with cystic fibrosis (pwCF). The success of highly effective modulator therapy (HEMT) permits evaluation of treatment simplification. In this review, we evaluate adjustments made in daily respiratory care among pwCF taking HEMT and the feasibility of treatment simplification.
Recent Findings: Treatment simplification has been identified as a top priority among pwCF, with recent studies showing pwCF are willing to sacrifice mild to moderate amounts of lung function and longevity to reduce treatment burden. Retrospective studies have shown that patients taking HEMT with better baseline lung function have lower adherence to and prescription of inhaled medications. A randomized, controlled trial found that short-term discontinuation of dornase alfa or hypertonic saline was clinically noninferior to continuation of these medications. Major knowledge gaps remain about withdrawing ACTs.
Summary: This review highlights trials evaluating the feasibility of treatment simplification among pwCF taking HEMT. More data is needed to evaluate approaches to simplification in this phenotypically diverse patient population.

Background: Highly effective CFTR modulators improve CFTR function and lead to dramatic improvements in health outcomes in many people with cystic fibrosis (pwCF). The relationship between measures of CFTR function, such as sweat chloride concentration, and clinical outcomes in pwCF treated with CFTR modulators is poorly defined. We conducted analyses to better understand the relationships between sweat chloride and CFTR function in vitro, and between sweat chloride and clinical outcomes following CFTR modulator treatment.

Introduction: The burden of severe asthma on patients, especially on those with concomitant chronic rhinosinusitis with nasal polyps (CRSwNP), is substantial. Treatment intensification with oral corticosteroids is a common strategy for managing severe asthma exacerbations; however, prolonged exposure to systemic corticosteroids is associated with multisystem toxicity. This study aimed to quantify the association between oral corticosteroid use and annual asthma-related costs in patients with severe asthma with or without CRSwNP.

Background: Adult people with cystic fibrosis (PwCF) have a higher risk of end-stage kidney disease than the general population. The nature and mechanism of kidney disease in CF are unknown. This study quantifies urinary kidney injury markers and examines the hypothesis that neutrophil activation and lung infection are associated with early kidney injury in CF.

Autosomal dominant polycystic kidney disease (ADPKD) is the fourth leading cause of end-stage renal disease, contributing substantially to patient morbidity, mortality, and healthcare system strain. Emerging research highlights a pivotal role of epigenetics in ADPKD's pathophysiology, where mechanisms like DNA methylation, histone modifications, and non-coding RNA regulation significantly impact disease onset and progression. These epigenetic factors influence gene expression and regulate key processes involved in cyst formation and expansion, fibrosis, and inflammatory infiltration, thus accelerating ADPKD progression.

Importance: Administrative health data serve as promising data sources to study transgender health at a population level in the absence of self-reported gender identity.
Objective: To develop and validate case definitions identifying transgender adults in administrative data compared with the reference standard of self-reported gender identity in a universal health care setting.
Design, Setting, And Participants: In this cohort study conducted in Alberta, Canada, data from provincial administrative health data sources including inpatient hospitalizations, emergency department encounters, primary care visits, prescription drug dispensations, and the provincial health insurance registry were linked and used to develop 15 case definitions (9 for transgender women and 6 for transgender men).
