RESUMO
BACKGROUND & AIMS: The long-term impact of perioperative probiotics remains understudied while mounting evidence links microbiome and oncogenesis. Therefore, we analyzed overall survival and cancer recurrence among patients enrolled in a randomized trial of perioperative probiotics. METHODS: 6-year follow-up of surgical patients participating in a randomized trial evaluating short-course perioperative oral probiotic VSL#3 (n = 57) or placebo (n = 63). RESULTS: Study groups did not differ in age, preoperative hemoglobin, ASA status, and Charlson comorbidity index. There was a significant difference in preoperative serum albumin (placebo group 4.0 ± 0.1 vs. 3.7 ± 0.1 g/dL in the probiotic group, p = 0.030). Thirty-seven deaths (30.8 %) have occurred during a median follow-up of 6.2 years. Overall survival stratified on preoperative serum albumin and surgical specialty was similar between groups (p = 0.691). Age (aHR = 1.081, p = 0.001), serum albumin (aHR = 0.162, p = 0.001), and surgical specialty (aHR = 0.304, p < 0.001) were the only predictors of overall survival in the multivariate model, while the placebo/probiotic group (aHR = 0.808, p = 0.726) was not predictive. The progression rate among cancer patients was similar in the probiotic group (30.3 %, 10/33) compared to the placebo group (21.2 %, 7/33; p = 0.398). The progression-free survival was not significantly different (unstratified p = 0.270, stratified p = 0.317). CONCLUSIONS: Perioperative short-course use of VSL#3 probiotics does not influence overall or progression-free survival after complex surgery for visceral malignancy.

Venoarterial extracorporeal membrane oxygenation is increasingly used for mechanical circulatory support during lung transplant. Optimal intensity of intraoperative anticoagulation would be expected to mitigate thromboembolism without increasing bleeding and blood product transfusions. Yet, the optimal intensity of intraoperative anticoagulation is unknown. We performed a retrospective cohort study of 163 patients who received a bilateral lung transplant at a single center. We categorized the intensity of anticoagulation into 4 groups (very low to high) based on the bolus dose of unfractionated heparin given during lung transplant and compared the rates of intraoperative blood transfusions and the occurrence of thromboembolism between groups. When compared to the very low-intensity group, each higher intensity group was associated with higher red blood cell, fresh frozen plasma, and platelet transfusions. The occurrence of thromboembolism was similar across groups. These preliminary data suggest that lower intensity anticoagulation may reduce the rate of intraoperative blood transfusions, although further study is needed.

OBJECTIVE: Intentionally self-driven professional development of surgical resident physicians is a hallmark of surgical training and is expected to gain further traction as Entrustable Professional Activities (EPAs) become the new paradigm for surgical education. We aimed to analyze how surgical residents rate themselves as compared to the evaluation of the Clinical Competency Committee using ACGME Milestones Version 1 (M1.0) and Version 2 (M2.0). DESIGN: We asked 22 general surgical trainees for self-evaluation of Milestones (both M1.0 and M2.0) from 2017 semiannually to 2022. ACGME-required Milestone evaluations by the Clinical Competency Committee (CCC) were independently performed after the time window for resident self-evaluation. Neither trainees nor CCC were aware of the other party's evaluations. There were 1552 paired data available for evaluating individual competencies by both trainees and CCC. Paired Wilcoxon signed-rank tests were then performed among the corresponding pairs. SETTING: MercyOne Des Moines Medical Center, Des Moines, IA; Teaching tertiary referral center. PARTICIPANTS: Twenty-two general surgical trainees at this hospital and 28 faculty surgeons participated in this study. RESULTS: The average self-evaluation of surgical residents was lower in the M1.0 cohort compared to the corresponding CCC evaluation (1.96 ± 0.72 vs. 2.11 ± 0.67; p < 0.001). M1.0 self-assessments and CCC-assessments were statistically similar for ICS (pâ¯=â¯0.548) and PROF (pâ¯=â¯0.554) competencies and differed for MK (p < 0.001), PBLI (p < 0.001), PC (p < 0.001), SBP (pâ¯=â¯0.008). On the contrary, the M2.0 cohort demonstrated higher average self-evaluation of surgical residents compared to the corresponding CCC evaluation (2.75 ± 0.87 vs. 2.12 ± 0.97; p < 0.001). Significant differences were observed for all 6 ACGME competencies using M2.0 self-assessments and CCC-assessments (all p < 0.001). Multivariate regression modeling (p < 0.001, R2â¯=â¯0.255) predicted the degree of discordance between self-assessment and CCC-assessed achievement of competencies with a significant effect of gender (baseline male: coefâ¯=â¯-0.232, p < 0.001), PGY level (-0.083 per year, p < 0.001) and Milestone version (0.831, p < 0.001). A significant interaction exists for all gender/Milestone combinations except for the female trainees with M1.0. CONCLUSIONS: The difference between self-evaluated Milestone achievement and faculty-driven CCC evaluation of surgical resident physician performance is more evident in Milestones 2.0 than in Milestones 1.0. Residents self-evaluate higher compared to faculty using Milestones 2.0. This discrepancy is seen among both genders and is more pronounced among male residents overestimating core competencies with M2.0 self-evaluation than formal CCC assessment.

The COVID-19 pandemic has uncovered disparities for allopathic and osteopathic surgical applicants for the upcoming 2021 residency application cycle. It has provided an opportunity for change to the current paradigm in surgical resident selection. This study seeks to quantify the disproportionality of opportunities between allopathic and osteopathic students and provides solutions to level the playing field for all applicants.
