Randomized Controlled Trial Multicenter Study
Antibiotics for lower respiratory tract infection in children presenting in primary care in England (ARTIC PC): a double-blind, randomised, placebo-controlled trial.
Antibiotic resistance is a global public health threat. Antibiotics are very commonly prescribed for children presenting with uncomplicated lower respiratory tract infections (LRTIs), but there is little evidence from randomised controlled trials of the effectiveness of antibiotics, both overall or among key clinical subgroups. In ARTIC PC, we assessed whether amoxicillin reduces the duration of moderately bad symptoms in children presenting with uncomplicated (non-pneumonic) LRTI in primary care, overall and in key clinical subgroups. ⋯ National Institute for Health Research.

Mortality remains unacceptably high in patients with heart failure and reduced left ventricular ejection fraction (LVEF) despite advances in therapeutics. We hypothesised that a novel artificial intelligence approach could better assess multiple and higher-dimension interactions of comorbidities, and define clusters of β-blocker efficacy in patients with sinus rhythm and atrial fibrillation. ⋯ Medical Research Council, UK, and EU/EFPIA Innovative Medicines Initiative BigData@Heart.

Fibrotic interstitial lung disease (ILD) represents a large group of pulmonary disorders that are often progressive and associated with high morbidity and early mortality. Important advancements in the past 10 years have enabled a better understanding, characterisation, and treatment of these diseases. This Series paper summarises the current approach to treatment of fibrotic ILDs, both pharmacological and non-pharmacological, including recent discoveries and practice-changing clinical trials. We further outline controversies and challenges, with discussion of evolving concepts and future research directions.

Vaccine effectiveness studies have not differentiated the effect of the delta (B.1.617.2) variant and potential waning immunity in observed reductions in effectiveness against SARS-CoV-2 infections. We aimed to evaluate overall and variant-specific effectiveness of BNT162b2 (tozinameran, Pfizer-BioNTech) against SARS-CoV-2 infections and COVID-19-related hospital admissions by time since vaccination among members of a large US health-care system. ⋯ Pfizer.
