SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…
Two-year clinical follow up of coronary drug-eluting stent in patients at high risk for coronary restenosis
OBJECTIVE: To evaluate the long-term follow up of patients at high risk for coronary restenosis. BACKGROUND: Drug-eluting stents (DES) have been proven to reduce restenosis and reintervention compared with bare-metal stents (BMS). Although the safety of DES is not different from that of BMS in the short-to-medium term, concern has arisen about the potential for late stent thrombosis related to delayed endothelialization of the stent struts. METHODS: Among 495 patients who underwent percutaneous coronary intervention between June 2004 and March 2005, we retrospectively identified a subset of 150 patients (30%) at high risk for coronary restenosis on the basis of angiographic characteristics …
