Brain health in Norwegian female former top-level football players: a protocol for a longitudinal cohort study.

Introduction: Repetitive head impacts (RHI) in sports may represent a risk factor for long-term cognitive and neurological sequelae. Recent studies have identified an association between playing football at the top level and an elevated risk of cognitive impairment and neurodegenerative disease. However, these were conducted on men, and there is a knowledge gap regarding these risks in female athletes.

Germline deletion of Rgs2 and/or Rgs5 in male mice does not exacerbate left ventricular remodeling induced by subchronic isoproterenol infusion.

Sympathoexcitation is a hallmark of heart failure, with sustained β-adrenergic receptor (βAR)-G protein signaling activation. βAR signaling is modulated by regulator of G protein signaling (RGS) proteins. Previously, we reported that Gα regulation by RGS2 or RGS5 is key to ventricular rhythm regulation, while the dual loss of both RGS proteins results in left ventricular (LV) dilatation and dysfunction.

Clinical importance of patient-reported outcome measures in severe asthma: results from U-BIOPRED.

Rationale: Knowledge about the clinical importance of patient-reported outcome measures (PROMs) in severe asthma is limited.

Objectives: To assess whether and to what extent asthma exacerbations affect changes in PROMS over time and asthma-specific PROMs can predict exacerbations in adult patients with severe asthma in usual care.

Methods: Data of 421 patients with severe asthma (62% female; mean age 51.

Development of an asthma health-care burden score as a measure of severity and predictor of remission in SARP III and U-BIOPRED: results from two major longitudinal asthma cohorts.

Background: Current asthma guidelines, including those of the European Respiratory Society (ERS) and American Thoracic Society (ATS), suboptimally predict asthma remission, disease severity, and health-care utilisation. We aimed to establish a novel approach to assess asthma severity based on asthma health-care burden data.

Methods: We analysed prospectively collected data from the Severe Asthma Research Program III (SARP III; USA) and the European Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED; 11 European countries) to calculate a composite burden score based on asthma exacerbations and health-care utilisation, which was modified to include the use of short-acting beta agonists (SABAs) to reflect asthma symptom burden.

Targeting of the IL-5 pathway in severe asthma reduces mast cell progenitors.

Background: Therapies targeting IL-5 or its receptor (IL-5Rα) are currently used to treat patients with severe eosinophilic asthma.

Objective: We sought to investigate the impact of anti-IL-5 and anti-IL-5Rα biological therapies on mast cells (MCs) and their progenitors.

Methods: Surface IL-5Rα expression was investigated on MCs and their progenitors in mouse lungs and bone marrow and in human lungs and blood.
