Post-migration HIV acquisition: A systematic review and meta-analysis.

Migrants in Europe face a disproportionate burden of HIV infection; however, it remains unclear if this can be prevented through public health interventions in host countries. We undertake a systematic review and meta-analysis to estimate post-migration HIV acquisition (PMHA) as a proportion of all HIV cases in European migrants. MEDLINE, EMBASE, Global Health, HMIC, and Cochrane Library were searched with terms capturing 'HIV', 'migration', and 'Europe'. Data relating to the proportion of HIV acquired following migration were extracted and random-effects model (REM) meta-analysis was undertaken to calculate a pooled estimate for the proportion of PMHA in European countries. Subgroup meta-analysis was undertaken for PMHA by migrant demographic characteristics and host country. Fifteen articles were included for systematic review following retrieval and screening of 2,320 articles. A total of 47,182 migrants in 11 European countries were included in REM meta-analysis, showing an overall PMHA proportion of 0.30 (95% CI: 0.23-0.38). Subgroup analysis showed no significant difference in PMHA between host country and migrant demographic characteristics. This work illustrates that migrants continue to be at high risk of HIV acquisition in Europe. This indicates the need for targeted screening and HIV prevention interventions, ensuring resources are appropriately directed to combat the spread of HIV.

Risk of Cervical Cancer in Inflammatory Bowel Disease: A Meta-Analysis of Population-Based Studies.

INTRODUCTION: There is increased risk of several malignancies in inflammatory bowel disease (IBD). However, evidence regarding risk of cervical cancer in IBD is conflicting. We aimed to investigate the risk of cervical cancer in IBD by undertaking a systematic review and meta-analysis of unselected, population-based studies. METHODS: MEDLINE, EMBASE, and Cochrane Library were searched using Medical Subject Heading terms, and 2 reviewers independently screened results. Pooled hazard ratios (HRs) were calculated using random effects model meta-analysis for risk of cervical cancer in IBD. Subgroup meta-analysis was undertaken to assess risk of cervical cancer by IBD subtype (Crohn's disease and ulcerative colitis), treatment exposure, and grade of lesion. RESULTS: We screened 1,393 articles to identify 5 population-based studies, including 74,310 patients with IBD and 2,029,087 reference patients, across 5 different countries. Pooled random effects model meta-analysis of these studies did not show statistically significant increased risk for cervical cancer in IBD compared with reference populations (HR: 1.24; 95% confidence interval [CI]: 0.94-1.63). Meta-analysis by grade of lesion showed increased risk of low-grade cervical lesions (HR: 1.15; 95% CI: 1.04-1.28). Meta-analysis by disease subtype indicated no statistically significant increased risk in Crohn's disease (HR: 1.36; 95% CI: 0.83-2.23) or ulcerative colitis (HR: 0.95; 95% CI: 0.72-1.25) or in patients treated with antitumor necrosis factor (HR: 1.19; 95% CI: 0.64-2.21) or thiopurines (HR: 0.96; 95% CI: 0.60-1.50). DISCUSSION: This meta-analysis of high-quality, unselected population-based studies shows no statistically significant increased risk of cervical cancer in patients with IBD. There is, however, increased risk of low-grade cervical lesions compared with the general population.

Medical Students' Corner: Lessons From COVID-19 in Equity, Adaptability, and Community for the Future of Medical Education.

As UK medical students, we recently completed 3 months of remote learning due to the COVID-19 pandemic, before taking online end-of-the-year exams. We are now entering our final year of medical school. Based on our experiences and our understanding of others' experiences, we believe that three key lessons have been universal for medical students around the world. The lessons learned throughout this process address the need for a fair system for medical students, the importance of adaptability in all aspects of medical education, and the value of a strong medical school community. These lessons can be applied in the years to come to improve medical education as we know it.
