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…
Beta-delayed neutron spectroscopy of $^{133}$In
The decay properties of In133 were studied in detail at the ISOLDE Decay Station. The implementation of the Resonance Ionization Laser Ion Source allowed separate measurements of its 9/2+ ground state (In133g) and 1/2− isomer (In133m). With the use of β-delayed neutron and γ spectroscopy, the decay strengths above the neutron separation energy were quantified in this neutron-rich nucleus for the first time. The allowed Gamow-Teller transition 9/2+→7/2+ was located at 5.93 MeV in the In133g decay with a logft=4.7(1). In addition, several neutron-unbound states were populated at lower excitation energies by the first-forbidden decays of In133g,m. We assigned spins and parities to those neutro…
Fat plug myringoplasty: Analysis of a safe procedure for small tympanic perforations
Objective: Assessment of value of fat plug myringoplasty as office-based procedure in small tympanic membrane perforations. Material and Methods: Prospective study of consecutive patients undergoing fat plug myringoplasty under local anesthesia. Minimum follow-up considered was 6 months, which included several microscopic examinations. All data were recorded and analyzed statistically. Results: 33 patients matched the inclusion criteria; the mean perforation size was 2.8 mm. No change in PTA was noted after surgery in the whole series. Recurrence of perforation was detected in 7 cases (21%), which was statistically related with the cause of perforation rather than location or size (p-value …
