AbstractMechanical breathing motions have a fundamental function in lung development and disease, but little is known about how they contribute to host innate immunity. Here we use a human lung alveolus chip that experiences cyclic breathing-like deformations to investigate whether physical forces influence innate immune responses to viral infection. Influenza H3N2 infection of mechanically active… Continue reading Mechanical control of innate immune responses against viral infection revealed in a human lung alveolus chip

Short- vs Standard-Course Outpatient Antibiotic Therapy for Community-Acquired Pneumonia in ChildrenThe SCOUT-CAP Randomized Clinical Trial
Childhood community-acquired pneumonia (CAP) is usually treated with 10 days of antibiotics. Shorter courses may be effective with fewer adverse effects and decreased potential for antibiotic resistance. Objective To compare a short (5-day) vs standard (10-day) antibiotic treatment strategy for CAP in young children. Design, Setting, and Participants Randomized double-blind placebo-controlled clinical trial in outpatient… Continue reading Short- vs Standard-Course Outpatient Antibiotic Therapy for Community-Acquired Pneumonia in ChildrenThe SCOUT-CAP Randomized Clinical Trial
Neutrophil-to-Lymphocyte Ratio Better Than High-Sensitivity C-Reactive Protein in Predicting Stroke-Associated Pneumonia in Afebrile Patients
To evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS) without fever and to clarify whether NLR has an advantage over high-sensitivity C-reactive protein (hs-CRP) in predicting SAP. Patients and Methods: A total of 434 patients with AIS without fever were assessed in this study. Multivariable… Continue reading Neutrophil-to-Lymphocyte Ratio Better Than High-Sensitivity C-Reactive Protein in Predicting Stroke-Associated Pneumonia in Afebrile Patients
Obstructive sleep apnoea and 12-month weight loss in adults with class 3 obesity attending a multidisciplinary weight management program
Although there is a strong association between obesity and obstructive sleep apnoea (OSA), the effects of OSA and CPAP therapy on weight loss are less well known. The aim of this study in adults with class 3 obesity attending a multidisciplinary weight management program was to assess the relationship between OSA and CPAP usage, and… Continue reading Obstructive sleep apnoea and 12-month weight loss in adults with class 3 obesity attending a multidisciplinary weight management program
SARS–CoV–2 #Spike Impairs #DNA Damage Repair and InhibitsV(D)J Recombination In Vitro
Severe acute respiratory syndrome coronavirus 2 (SARS–CoV–2) has led to the coronavirus disease 2019 (COVID–19) pandemic, severely affecting public health and the global economy.Adaptive immunity plays a crucial role in fighting against SARS–CoV–2 infection and directly in-fluences the clinical outcomes of patients. Clinical studies have indicated that patients with severeCOVID–19 exhibit delayed and weak adaptive… Continue reading SARS–CoV–2 #Spike Impairs #DNA Damage Repair and InhibitsV(D)J Recombination In Vitro
#Zinc for the prevention or treatment of acute viral #respiratory tract infections in adults: a rapid systematic review and meta-analysis of randomised controlled trials
To evaluate the benefits and risks of zinc formulations compared with controls for prevention or treatment of acute viral respiratory tract infections (RTIs) in adults. Method Seventeen English and Chinese databases were searched in April/May 2020 for randomised controlled trials (RCTs), and from April/May 2020 to August 2020 for SARS-CoV-2 RCTs. Cochrane rapid review methods… Continue reading #Zinc for the prevention or treatment of acute viral #respiratory tract infections in adults: a rapid systematic review and meta-analysis of randomised controlled trials
#Metoprolol in Critically Ill Patients With COVID-19
Severe coronavirus disease-2019 (COVID-19) can progress to an acute respiratory distress syndrome (ARDS), which involves alveolar infiltration by activated neutrophils. The beta-blocker metoprolol has been shown to ameliorate exacerbated inflammation in the myocardial infarction setting. ObjectivesThe purpose of this study was to evaluate the effects of metoprolol on alveolar inflammation and on respiratory function in… Continue reading #Metoprolol in Critically Ill Patients With COVID-19
Sudden death in individuals with obstructive sleep #apnoea: a systematic review and meta-analysis
Over 1 billion individuals worldwide experience some form of sleep apnoea, and this number is steadily rising. Obstructive sleep apnoea (OSA) can negatively influence one’s quality of life and potentially increase mortality risk. However, the association between OSA and mortality has not been reliably estimated. This meta-analysis estimates the risk of all-cause and cardiovascular mortality in… Continue reading Sudden death in individuals with obstructive sleep #apnoea: a systematic review and meta-analysis
The noradrenergic agent reboxetine plus antimuscarinic hyoscine butylbromide reduces sleep #apnoea severity: A double-blind, placebo-controlled, randomised crossover trial
Recent animal and human physiology studies indicate that noradrenergic and muscarinic processes are key mechanisms that mediate pharyngeal muscle control during sleep. The noradrenergic agent reboxetine combined with the anti-muscarinic hyoscine butylbromide has recently been shown to improve upper airway function during sleep in healthy individuals. However, whether these findings translate to the clinically relevant… Continue reading The noradrenergic agent reboxetine plus antimuscarinic hyoscine butylbromide reduces sleep #apnoea severity: A double-blind, placebo-controlled, randomised crossover trial
