Background The COVID-19 pandemic has resulted in significant changes to healthcare systems which impact the delivery of surgical training. This study aimed to investigate the qualitative impact of COVID-19 on surgical training in the United Kingdom (UK) & Republic of Ireland (ROI) Methods This national, collaborative, cross-sectional study involving 13 surgical trainee associations distributed a pan-surgical specialty questionnaire on the impact of COVID-19 on surgical training over 4 weeks in May 2020. Various aspects of training were assessed. Results 810 completed responses were analysed (males=401, females=390) from all deaneries and training grades. The perceived negative overall impact of the pandemic on surgical training experience was significant. (Weighted average = 8.66). 41% of respondents (n=301) were redeployed with 74% redeployed >4 weeks. Complete loss of training was reported in elective operating (69.5%), outpatient activity (67.3%) and endoscopy (69.5%). A reduction of >50% was reported in emergency operating (48%) and completion of work-based assessments (WBAs) (46%). 3.3% (n= 17) of respondents reported plans to leave medicine altogether. Cancellations in study leave and regional teaching programmes without rescheduling were reported in 72% and 60% of the cohort respectively. Elective operative exposure and WBAs completion were the primary reported factors affecting potential trainee progression. Only 9% reported that they would definitely meet all required competencies. Conclusion COVID-19 has had a negative impact on surgical training across all grades and specialties, with implications for trainee progression, recruitment and retention of the surgical workforce. Further investigation of the long-term impact at a national level is required.

Pregnancy-associated malaria, a manifestation of severe malaria, is the cause of up to 200,000 infant deaths a year, through the effects of placental insufficiency leading to growth restriction and preterm delivery. Development of a vaccine is one strategy for control.Plasmodium falciparum-infected red blood cells accumulate in the placenta through specific binding of pregnancy-associated parasite variants that express the VAR2CSA antigen to chondroitin sulphate A on the surface of syncytiotrophoblast cells. Parasite accumulation, accompanied by an inflammatory infiltrate, disrupts the cytokine balance of pregnancy with the potential to cause placental damage and compromise foetal growth. Multigravid women develop immunity towards VAR2CSA-expressing parasites in a gravidity-dependent manner which prevents unfavourable pregnancy outcomes. Although current vaccine design, targeting VAR2CSA antigens, has succeeded in inducing antibodies artificially, this candidate may not provide protection during the first trimester and may only protect those women living in areas endemic for malaria. It is concluded that while insufficient information about placental-parasite interactions is presently available to produce an effective vaccine, incremental progress is being made towards achieving this goal.
