Predictors of Cytomegalovirus Recurrence Following Cessation of Posttransplant Prophylaxis.

INTRODUCTION: Cytomegalovirus (CMV) infection is associated with a poor prognosis after lung transplantation, and donor and recipient CMV serostatus is a risk factor for reactivation. CMV prophylaxis is commonly administered in the first year following transplantation to reduce CMV infection; however, the risk factors for long-term reactivation remain unclear. We investigated the timing and risk factors of CMV infection after prophylactic administration. METHODS: This study was a retrospective review of the institutional lung transplantation database from June 2014 to June 2022. Data on patient characteristics, pretransplantation laboratory values, postoperative outcomes, and CMV infection were collected. Donor CMV-IgG-positive and recipient CMV-IgG-negative groups were defined as the CMV mismatch group. RESULTS: During the study period, 257 patients underwent lung transplantation and received a prophylactic dose of valganciclovir hydrochloride for up to 1 y. CMV infection was detected in 69 patients (26.8%): 40 of 203 (19.7%) in the non-CMV mismatch group and 29 of 54 (53.7%) in the CMV mismatch group (P < 0.001). CMV infection after prophylaxis occurred at a median of 425 and 455 d in the CMV mismatch and non-CMV mismatch groups, respectively (P = 0.07). Multivariate logistic regression analysis revealed that preoperative albumin level (odds ratio [OR] = 0.39, P = 0.04), CMV mismatch (OR = 15.7, P < 0.001), and donor age (OR = 1.05, P = 0.009) were significantly associated with CMV infection. CONCLUSIONS: CMV mismatch may have increased the risk of CMV infection after lung transplantation, which decreased after prophylaxis. In addition to CMV mismatch, low preoperative albumin level and donor age were independent predictors of CMV infection.

Residents Need a Dynamic Approach to Leadership Education: A Qualitative Study.

OBJECTIVE: Leadership is an essential skill for surgeons, but it is not systematically taught in residency. The objective of this study was to explore the current experiences, motivators, and perspectives on leadership training of general surgery residents. DESIGN/SETTING/PARTICIPANTS: Semi-structured focus groups were conducted with 20 general surgery residents at an academic training program. Six in-person sessions (one for each postgraduate year and research) were recorded, transcribed, and de-identified. Data were inductively coded by 2 independent researchers and analyzed thematically. Discrepancies were discussed and resolved through consensus. RESULTS: Participants described developing their leadership skills prior to residency through formal (e.g., job and military) and informal (e.g., extracurricular) experiences. Most reported that leadership development during residency occurred informally (e.g., emulating mentors, trial-and-error). Evolving responsibilities and expectations shaped residents' leadership values: junior residents focused on student and task management and adaptation to new teams; mid-level residents emphasized emotional intelligence and delivery of resident feedback; and senior residents stressed team engagement, inspiring the team, and teaching/mentoring. Major transition periods between residency levels were identified as critical times for leadership training as they allow for self-reflection, motivating residents to participate in a leadership curriculum. Employing level appropriate and immediately applicable content during this time would encourage curriculum attendance and prepare residents for new roles. CONCLUSIONS: There is a lack of formal leadership training in general surgery residency. There is an opportunity to design and implement leadership training that engages surgical residents with level-relevant content and strategies. Transition periods offer optimal timing for maximal curricula uptake.

Single-Center Experience With Lung Transplant Evaluation Referrals of Acute Respiratory Distress Syndrome Patients During the COVID-19 Pandemic: How Do You Make Up For Lost Time?

Transfer of select, medically refractory acute respiratory distress syndrome patients to lung transplant centers requires extensive resources. Here, we report 270 consecutive lung transplant patient referrals to our center for medically refractory ARDS from June 2021 to April 2022, following the implementation of clinical care pathways for intake of these patients. Eighty-seven of 270 patients (32.2%) met screening criteria and were evaluated for transfer within a median of 12 days, during which 38 of 87 patients (43.7%) died and 12 of 87 patients (13.8%) transferred elsewhere. Thirty-seven of 87 patients (42.5%) were accepted for transfer of which 16 of 37 patients (43.2%) successfully transferred to our center with a median transfer waiting period of 12 days. Because of resource constraints, 21 of 37 accepted patients (56.8%) could not be transferred of which 9 of 21 patients (42.9%) died while waiting. Nine of 16 transferred patients (56.2%) eventually underwent lung transplantation with over 80% 6-month survival. ARDS patients referred for transplantation have high risk of mortality and, therefore, require well-described pathways for evaluation and transfer.

Lung transplantation for coronavirus disease 2019 acute respiratory distress syndrome/fibrosis: silver lining of a global pandemic.

PURPOSE OF REVIEW: The COVID-19 pandemic revolutionized the field of lung transplantation, as lung transplant is now an acceptable life-saving therapy for select patients with COVID-19-associated acute respiratory distress syndrome (ARDS), while prior to the pandemic, few transplants were performed for ARDS. This review article details the establishment of lung transplantation as a viable therapy for COVID-19-related respiratory failure, how to evaluate COVID-19 patients for lung transplant, and specific technical considerations for the operation. RECENT FINDINGS: Lung transplantation is a life-altering treatment for two distinct cohorts of COVID-19 patients: those with irrecoverable COVID-19-associated ARDS and those who recover from the initial COVID-19 insult but are left with chronic, debilitating post-COVID fibrosis. Both cohorts require stringent selection criteria and extensive evaluation to be listed for lung transplantation. As the first COVID-19 lung transplantation was recently performed, long-term outcomes are lacking; however, short-term outcome data of COVID-19-related lung transplants are promising. SUMMARY: Given the challenges and complexities associated with COVID-19-related lung transplantation, strict patient selection and evaluation are required with an experienced multidisciplinary team at a high-volume/resource center. With promising short-term outcome data, ongoing studies are needed to assess long-term outcomes of COVID-19-related lung transplants.
