SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
2021
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…
Cochlear implant complications and failures
2010
Abstract Introduction Cochlear implantation is a relatively safe surgery performed on profound bilateral hearing loss patients. Its surgical indications have increased and the age of implantation has decreased over the last years. As with any other surgery, it presents complications; device failure is one of the most important, given its potential risk for the need to explant and reimplant the device. Objective To evaluate cochlear implant complications, determine possible causes and discuss medical and surgical management. Material and methods A retrospective study of cochlear implants was performed. A total of 246 implants over an eleven-year period were evaluated. The sample consisted of…
