Background Many people recovering from coronavirus disease 2019 (COVID-19) experience prolonged symptoms, particularly breathlessness. We urgently need to identify safe and effective COVID-19 rehabilitative strategies. The aim of the current study was investigate potential role inspiratory muscle training (IMT). Methods 281 adults (age 46.6±12.2 years; 88% female) self-reported (9.0±4.2 months post-acute infection) were randomised 4:1 an 8-week IMT or a “usual care” waitlist control arm....

Risk factors for severe COVID-19 include older age, male sex, obesity, black or Asian ethnicity and underlying medical conditions. Whether these also influence susceptibility to developing is uncertain.We undertook a prospective, population-based cohort study (COVIDENCE UK) from 1 May 2020 5 February 2021.

Antibody responses to SARS-CoV-2 vaccines vary for reasons that remain poorly understood. A range of sociodemographic, behavioural, clinical, pharmacologic and nutritional factors could explain these differences. To investigate this hypothesis, we tested presence combined IgG, IgA IgM (IgGAM) anti-Spike antibodies before after 2 doses ChAdOx1 nCoV-19 (ChAdOx1, AstraZeneca) or BNT162b2 (Pfizer-BioNTech) in UK adults participating a population-based longitudinal study who received their first...

There is currently no consensus on approaches to defining asthma or assessing outcomes using electronic health record-derived data. We explored these in the recent literature and examined clarity of reporting. systematically searched for asthma-related articles published between January 1, 2014 December 31, 2015, extracted algorithms used identify patients assess severity, control exacerbations, how validity was justified. From 113 eligible articles, we found significant heterogeneity define...
