Fostering bidirectional trainee-led partnerships through a technology-assisted journal club - The GASOC experience.

Since 2017, the Global Anaesthesia Surgery and Obstetric Collaboration (GASOC) has been hosting journal clubs to promote critical appraisal of global surgery publications. The COVID-19 pandemic has prompted a transition to an online-only journal club format. Attendees have rated the online GASOC journal clubs highly in terms of relevance for their learning and development, and the ability to engage with discussions. This transition has allowed more trainees in low- and middle-income countries (LMICs) to register for journal clubs, but barriers have continued to restrict their participation. Feedback submitted by participants has allowed GASOC to identify and address these barriers in order to promote bidirectional partnerships between high-income country and LMIC trainees.

Undergraduate Surgical Education: a Global Perspective.

Undergraduate surgical education is failing to prepare medical students to care for patients with surgical conditions, and has been significantly compromised by the COVID-19 pandemic. We performed a literature review and undertook semi-structured reflections on the current state of undergraduate surgical education across five countries: Egypt, Morocco, Somaliland, Kenya, and the UK. The main barriers to surgical education at medical school identified were (1) the lack of standardised surgical curricula with mandatory learning objectives and (2) the inadequacy of human resources for surgical education. COVID-19 has exacerbated these challenges by depleting the pool of surgical educators and reducing access to learning opportunities in clinical environments. To address the global need for a larger surgical workforce, specific attention must be paid to improving undergraduate surgical education. Solutions proposed include the development of a standard surgical curriculum with learning outcomes appropriate for local needs, the incentivisation of surgical educators, the incorporation of targeted online and simulation teaching, and the use of technology.

Systematic analysis of authorship demographics in global surgery.

BACKGROUND: Global surgery has recently gained prominence as an academic discipline within global health. Authorship inequity has been a consistent feature of global health publications, with over-representation of authors from high-income countries (HICs), and disenfranchisement of researchers from low-income and middle-income countries (LMICs). In this study, we investigated authorship demographics within recently published global surgery literature. METHODS: We performed a systematic analysis of author characteristics, including gender, seniority and institutional affiliation, for global surgery studies published between 2016 and 2020 and indexed in the PubMed database. We compared the distribution of author gender and seniority across studies related to different topics; between authors affiliated with HICs and LMICs; and across studies with different authorship networks. RESULTS: 1240 articles were included for analysis. Most authors were male (60%), affiliated only with HICs (51%) and of high seniority (55% were fully qualified specialist or generalist clinicians, Principal Investigators, or in senior leadership or management roles). The proportion of male authors increased with increasing seniority for last and middle authors. Studies related to Obstetrics and Gynaecology had similar numbers of male and female authors, whereas there were more male authors in studies related to surgery (69% male) and Anaesthesia and Critical care (65% male). Compared with HIC authors, LMIC authors had a lower proportion of female authors at every seniority grade. This gender gap among LMIC middle authors was reduced in studies where all authors were affiliated only with LMICs. CONCLUSION: Authorship disparities are evident within global surgery academia. Remedial actions to address the lack of authorship opportunities for LMIC authors and female authors are required.

Changes in the Vα7.2+ CD161++ MAIT cell compartment in early pregnancy are associated with preterm birth in HIV-positive women.

PROBLEM: Human immunodeficiency virus (HIV) infection is associated with an increased risk of adverse pregnancy outcomes, including preterm birth (PTB), despite viral suppression with antiretroviral therapy. Mucosal-associated invariant T (MAIT) cells are an immune cell subset involved in antimicrobial immunity at mucosal surfaces. MAIT cells have been found at the maternal-foetal interface, and MAIT cells are typically depleted early in HIV infection. We aimed to investigate changes in MAIT cells in relation to maternal HIV/ART status and PTB. METHOD OF STUDY: We conducted flow cytometric analysis of peripheral blood samples from 47 HIV-positive (HIV+) and 45 HIV-negative (HIV-) pregnant women enrolled in a prospective pregnancy cohort study in Soweto, South Africa. Frequencies of Vα7.2+ CD161++ MAIT cells and proportions of CD4+ , CD8+ and double-negative MAIT cells were compared between women with and without HIV infection, and between women with and without PTB or spontaneous preterm labour (Sp-PTL). RESULTS: Although overall MAIT cell frequencies were the same between HIV+ and HIV- patients, HIV+ patients had a higher proportion of CD8+ MAIT cells in the first two trimesters. Women with PTB and Sp-PTL also had a higher proportion of CD8+ MAIT cells in the first trimester compared to women without these outcomes. The association between changes in MAIT cell subsets and PTB/Sp-PTL was present in both HIV+ and HIV- women, and an additive effect on MAIT cell subsets was seen in women with both HIV infection and PTB. CONCLUSIONS: Interactions between HIV-related and pregnancy-related changes in MAIT cell subsets and distribution may lead to imbalances in peripheral MAIT cell subsets in early pregnancy. This may contribute to the increased risk of PTB in HIV+ patients by altering the overall functionality of the peripheral MAIT cell compartment.
