Foundation doctors' perspectives on the impact of the COVID-19 pandemic and lessons for the future.

The foundation programme is a 2-year training programme for newly qualified doctors and aims to bridge the gap between medical school and specialty training. The pandemic led to some major disruptions to foundation training. As foundation trainees, we encountered new challenges: there were reduced learning opportunities and our future paths became uncertain with changes to specialty training applications and membership exams. However, it is said that every crisis creates new opportunities and is a test of our resilience and innovativeness. There was the adoption of novel teaching methods, new research opportunities, increased importance given to teamwork and support for our wellbeing and mental health. We learnt lessons from this crisis that we should take forward to improve foundation training for the future.

Preoperative Cardiovascular Assessment of the Renal Transplant Recipient: A Narrative Review.

Patients with end-stage kidney disease (ESKD) have a high prevalence of cardiovascular disease; it is the leading cause of death in these patients and the optimisation of their cardiovascular health may improve their post-transplant outcomes. Patients awaiting renal transplant often spend significant amounts of time on the waiting list allowing for the assessment and optimisation of their cardiovascular system. Coronary artery disease (CAD) is commonly seen in these patients and we explore the possible functional and anatomical investigations that can help assess and manage CAD in renal transplant candidates. We also discuss other aspects of cardiovascular assessment and management including arrhythmias, impaired ventricular function, valvular disease, lifestyle and pulmonary arterial hypertension. We hope that this review can form a basis for centres hoping to implement an enhanced recovery after surgery (ERAS) protocol for renal transplantation.

Gender Disparity in Abstract Presentation at Plastic Surgery Meetings.

BACKGROUND: Medical and surgical fields continue to be marred by gender disparities. The "leaky pipeline" effect, representing a gradual decline in female representation along the academic ladder, has been well documented in plastic surgery. However, gender differences in abstract presentation at national plastic surgery meetings and subsequent publications remains elusive. METHODS: We reviewed abstracts presented at the 2014 and 2015 annual meetings of the American Association of Plastic Surgeons (AAPS); American Society of Plastic Surgeons (ASPS), and the Plastic Surgery Research Council (PSRC). Several abstract characteristics including the names of the first and last authors were extracted. Genderize.io and Google search were used to identify the authors' gender. RESULTS: We identified 1174 abstracts presented at the three identified meetings. Females comprised 29% of the presenters and 16% of abstract senior authors (ASAs). No gender differences were identified between the meetings, type of presentation (oral versus poster), and year of presentation. The only difference was in the subspecialty of the abstracts. Successful conversion to full-text articles was similar for male and female presenters (68% versus 62%, P = 0.065) but higher for male ASAs (68% versus 59%, P = 0.01). When an author change occurred, female presenters and ASAs were more likely to be replaced by males (P < 0.001). CONCLUSION: Gender differences continue to be evident in academic plastic surgery with women constituting a minority of both presenters and senior authors on abstracts presented at national plastic surgery meetings. Future work should assess whether flexible and supportive work policies can foster greater female representation in academic plastic surgery.

Working towards an ERAS Protocol for Pancreatic Transplantation: A Narrative Review.

Enhanced recovery after surgery (ERAS) initially started in the early 2000s as a series of protocols to improve the perioperative care of surgical patients. They aimed to increase patient satisfaction while reducing postoperative complications and postoperative length of stay. Despite these protocols being widely adopted in many fields of surgery, they are yet to be adopted in pancreatic transplantation: a high-risk surgery with often prolonged length of postoperative stay and high rate of complications. We have analysed the literature in pancreatic and transplantation surgery to identify the necessary preoperative, intra-operative and postoperative components of an ERAS pathway in pancreas transplantation.

Critical Role of B Cells in Toll-Like Receptor 7-Mediated Protection against Listeria monocytogenes Infection.

Toll-like receptors (TLR) trigger the immune system to mount a rapid innate response capable of protecting the host from a wide variety of bacterial and viral pathogens. There is interest in harnessing TLR agonists to reduce the susceptibility of at-risk populations to infection. However, the widespread prophylactic use of TLR agonists has been compromised by the need to administer them by parenteral injection. An exception is the TLR7/8 agonist R848, which can boost gastrointestinal and systemic immunity when administered orally. This work examines the effect of R848 on host susceptibility to Listeria monocytogenes in a murine challenge model and describes the underlying mechanisms. Results show that prophylactic administration of R848 significantly reduces susceptibility to infection of BALB/c mice, an effect that lasts 1 week. Oral R848 directly stimulated B cells to produce cytokines and Ig. In the absence of B cells, R848-mediated protection was lost. These findings support the use of oral R848 to reduce the susceptibility of at-risk individuals to infection and identify the critical role of B cells in TLR7-mediated resistance to bacterial infection.

Assessment of human leukocyte antigen immunogenicity: current methods, challenges and opportunities.

PURPOSE OF REVIEW: Donor-recipient human leukocyte antigen (HLA) matching improves outcomes after solid-organ transplantation, but current assessment of HLA incompatibility is inadequate as it does not consider the relative immunogenicity of individual HLA mismatches. In this article, we review existing strategies for assessing HLA immunogenicity and discuss current challenges and future opportunities in this field. RECENT FINDINGS: Current HLA immunogenicity algorithms focus primarily on the humoral component of the alloimmune response and aim to determine a measure of 'dissimilarity' between donor and recipient HLA. This can be achieved by deriving information from comparison of donor and recipient HLA at the amino acid sequence, structural and/or the physicochemical level, accounting for both B-cell and T-cell pathways of alloreactivity. Substantial evidence now supports the superiority of this molecular definition of HLA incompatibility, over conventional enumeration of HLA antigenic differences, for assessing the risk of humoral alloimmunity and for predicting graft outcomes after transplantation. SUMMARY: Significant progress has been made in developing computational HLA immunogenicity algorithms that offer exciting opportunities for a more rational approach to determining the degree of donor-recipient HLA incompatibility and to defining HLA-related immunological risk. A number of challenges now need to be overcome to enable their implementation into clinical practice.
