Comparison of transcatheter and surgical aortic valve replacement long-term outcomes: a retrospective cohort study with overlap propensity score weighting

Background and aims Randomised controlled trials comparing transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) were performed in highly selected populations and data regarding long-term secondary complications beyond mortality are scarce. This study used data from Ontario,

Recognising value

Sciatica is a common condition. How much better is surgery at relieving pain and disability than non-surgical treatments or steroid injections? Liu and colleagues conducted a systematic review and meta-analysis to answer this question (doi:10.1136/bmj-2022-070730).1 The certainty of the evidence

Skin Cancer Screening

The US Preventive Services Task Force (USPSTF) initially released its skin cancer screening recommendations in 1996 and concluded that there was not enough evidence to recommend skin examinations for the early detection of skin cancer in adults. They recently released

Inference of chronic obstructive pulmonary disease with deep learning on raw spirograms identifies new genetic loci and improves risk models

Nature Genetics, Published online: 17 April 2023; doi:10.1038/s41588-023-01372-4 A deep convolutional neural network calculates liability scores for chronic obstructive pulmonary disease (COPD) from raw spirogram traces and noisy medical-record-based labels in the UK Biobank. Genome-wide analyses using these scores replicate

Utilisation, effectiveness, and safety of immediate postpartum intrauterine device insertion: a systematic literature review

Background Intrauterine devices (IUDs) are highly effective contraception. IUDs inserted directly following delivery provide immediate birth control and may decrease unintended pregnancies, including short-interval pregnancies, thereby mitigating health risks and associated economic burden. Methods This systematic literature review included published
