Introduction Pneumothorax and pneumomediastinum have both been noted to complicate cases of coronavirus disease 2019 (COVID-19) requiring hospital admission. We report the largest case series yet described patients with these pathologies (including nonventilated patients). Methods Cases were collected retrospectively from UK hospitals inclusion criteria limited a diagnosis COVID-19 presence either pneumothorax or pneumomediastinum. Patients included in study presented between March June...

Reduction of the risk asthma attacks is a major goal current management. We propose to derive scale predicting based on blood eosinophil count and exhaled nitric oxide (FeNO). Biomarker-stratified trial-level attack rates were extracted pooled from control arms Novel START, CAPTAIN, QUEST, Benralizumab Phase 2b, PATHWAY, STRATOS 1-2 DREAM trials (n=3051). These used rate ratios predicted for different patient groups. The resultant prototype shows potential predict attacks, which may be...

Background There is an emerging understanding that coronavirus disease 2019 (COVID-19) associated with increased incidence of pneumomediastinum (PTM). We aimed to determine its among patients hospitalised COVID-19 in the UK and describe factors outcome. Methods A structured survey PTM was conducted from September 2020 February 2021. UK-wide participation solicited via respiratory research networks. Identified had severe acute syndrome 2 (SARS-CoV-2) infection radiologically proven PTM. The...

Hintergrund: Exazerbationen von Asthma und chronisch-obstruktiver Lungenerkrankung (COPD) sind wichtige Ereignisse, die mit kritischen Erkrankungen einhergehen. Die eosinophile Entzündung ist ein behandelbares Symptom, das häufig bei akuten COPD auftritt. Wir stellten Hypothese auf, dass Patienten eosinophilen eine einmalige Injektion Benralizumab, einem humanisierten monoklonalen Antikörper, der gegen den Interleukin-5-Rezeptor alpha gerichtet ist, allein oder in Kombination Prednisolon...

Cumulative trauma disorders account for 56% of all occupational injuries. Currently, injuries affect 15% to 20% Americans. The United States government predicts that by the year 2000, 50% American workforce will have annually and 50 cents every dollar be spent on cumulative disorders. There is common agreement need reduction in workplace. However, there little appropriate definition musculoskeletal pain occurs workplace, or ergonomic epidemiologic model disorders, specific exposure...

Diagnostic screening tests for carpal tunnel syndrome (CTS) have not been rigorously assessed in large populations.This study is a cross-sectional analysis from prospective cohort study. Participants' (n = 1,194) symptoms and disease prevalence were measured. Sensitivity, specificity, positive negative predictive values (NPVs) calculated.When defining CTS as tingling/numbness at least two median nerve-served digits an abnormal nerve conduction study, the was 8.9%.
