Impact of penicillin allergy labels on surgical site infections in a large UK cohort of gastrointestinal surgery patients.

Objectives: Studies in the USA, Canada and France have reported higher surgical site infection (SSI) risk in patients with a penicillin allergy label (PAL). Here, we investigate the association between PALs and SSI in the UK, a country with distinct epidemiology of infecting pathogens and range of antimicrobial regimens in routine use.

Methods: Electronic health records and national SSI surveillance data were collated for a retrospective cohort of gastrointestinal surgery patients at Cambridge University Hospitals NHS Foundation Trust from 1 January 2015 to 31 December 2021.

Performance of spirometry assessment at TB diagnosis.

Spirometry is considered relevant for the diagnosis and monitoring of post-TB lung disease. However, spirometry is rarely done in newly diagnosed TB patients. Newly diagnosed, microbiologically confirmed TB patients were recruited for the study.

Long-term safety and immunogenicity of an MF59-adjuvanted spike glycoprotein-clamp vaccine for SARS-CoV-2 in adults aged 18-55 years or ≥56 years: 12-month results from a randomised, double-blind, placebo-controlled, phase 1 trial.

Background: We previously demonstrated the safety and immunogenicity of an MF59-adjuvanted COVID-19 vaccine based on the SARS-CoV-2 spike glycoprotein stabilised in a pre-fusion conformation by a molecular clamp using HIV-1 glycoprotein 41 sequences. Here, we describe 12-month results in adults aged 18-55 years and ≥56 years.

Methods: Phase 1, double-blind, placebo-controlled trial conducted in Australia (July 2020-December 2021; ClinicalTrials.

Postdischarge prognostic significance of periprocedural myocardial injury after percutaneous intervention of chronic total occlusion.

Background: The postdischarge prognostic implication of periprocedural myocardial injury in patients undergoing percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) remains scarcely studied.

Aims: The aim of this study is to assess the prognostic value of periprocedural myocardial injury, defined by increased high-sensitive troponin T (hs-TnT) levels according to updated guidelines, after CTO PCI.

Methods: Between September 2011 and April 2020, 726 patients undergoing CTO PCI at 2 Belgian referral centres were prospectively included and divided into 4 groups based on postprocedural hs-TnT levels (unelevated; ≥5 times the upper limit of normal (ULN); ≥35 times the ULN; ≥70 times the ULN).

A minimal monitoring approach for the treatment of hepatitis C virus infection (ACTG A5360 [MINMON]): a phase 4, open-label, single-arm trial.

Background: Despite widespread availability of direct-acting antivirals including generic formulations, limited progress has been made in the global adoption of hepatitis C virus (HCV) treatment. Barriers to treatment scale-up include availability and access to diagnostic and monitoring tests, health-care infrastructure, and requirement for frequent visits during treatment.

Methods: ACTG A5360 was a phase 4, open-label, single-arm trial across 38 sites in Brazil, South Africa, Thailand, Uganda, and the USA.
