RESUMEN

OBJECTIVE: The Vascular Surgery In-Training Examination (VSITE) is a yearly exam evaluating vascular trainees' knowledge base. Although multiple studies have evaluated variables associated with exam outcomes, few have incorporated training program-specific metrics. The purpose of this study is to evaluate the impact of the learning environment and burnout on VSITE performance. METHODS: Data was collected from a confidential, voluntary survey administered after the 2020 to 2022 VSITE as part of the SECOND Trial. VSITE scores were calculated as percent correct then standardized per the American Board of Surgery. Generalized estimating equations with robust standard errors and an independent correlation structure were used to evaluate trainee and program factors associated with exam outcomes. Analyses were further stratified by integrated and independent training paradigms. RESULTS: A total of 1385 trainee responses with burnout data were collected over 3 years (408 in 2020, 459 in 2021, 498 in 2022). On average, 46% of responses reported at least weekly burnout symptoms. On unadjusted analysis, burnout symptoms correlated with a 14 point drop in VSITE score (95% confidence interval [CI], -24 to -4; P = .006). However, burnout was no longer significant after adjusted analysis. Instead, higher postgraduate year level, being in a relationship, identifying as male gender with or without kids, identifying as non-Hispanic white, larger programs, and having a sense of belonging within a program were associated with higher VSITE scores. CONCLUSIONS: Despite high rates of burnout, trainees generally demonstrate resilience in gaining the medical knowledge necessary to pass the VSITE. Performance on standardized exams is associated with trainee and program characteristics, including availability of support systems and program belongingness.

RESUMEN

BACKGROUND: Work-related pain is a known risk factor for vascular surgeon burnout. It risks early attrition from our workforce and is a recognized threat to the specialty. Our study aimed to understand whether work-related pain similarly contributed to vascular surgery trainee well-being. METHODS: A confidential, voluntary survey was administered after the 2022 Vascular Surgery In-Service Examination to trainees in all Accreditation Council for Graduate Medical Education-accredited vascular surgery programs. Burnout was measured by a modified, abbreviated Maslach Burnout Inventory; pain after a full day of work was measured using a 10-point Likert scale and then dichotomized as "no to mild pain" (0-2) vs "moderate to severe pain" (3-9). Univariable analyses and multivariable regression assessed associations of pain with well-being indicators (eg, burnout, thoughts of attrition, and thoughts of career change). Pain management strategies were included as additional covariables in our study. RESULTS: We included 527 trainees who completed the survey (82.2% response rate); 38% reported moderate to severe pain after a full day of work, of whom 73.6% reported using ergonomic adjustments and 67.0% used over-the-counter medications. Significantly more women reported moderate to severe pain than men (44.3% vs 34.5%; P < .01). After adjusting for gender, training level, race/ethnicity, mistreatment, and dissatisfaction with operative autonomy, moderate-to-severe pain (odds ratio, 2.52; 95% confidence interval, 1.48-4.26) and using physiotherapy as pain management (odds ratio, 3.06; 95% confidence interval, 1.02-9.14) were risk factors for burnout. Moderate to severe pain was not a risk factor for thoughts of attrition or career change after adjustment. CONCLUSIONS: Physical pain is prevalent among vascular surgery trainees and represents a risk factor for trainee burnout. Programs should consider mitigating this occupational hazard by offering ergonomic education and adjuncts, such as posture awareness and microbreaks during surgery, early and throughout training.

RESUMEN

OBJECTIVE: We sought to quantify the percent calcification within carotid artery plaques and assess its impact on percent residual stenosis and rate of restenosis in patients undergoing transcarotid artery revascularization for symptomatic and asymptomatic carotid artery stenosis. METHODS: A retrospective review of prospectively collected institutional Vascular Quality Initiative data was performed to identify all patients undergoing transcarotid artery revascularization from December 2015 to June 2021 (n = 210). Patient and lesion characteristics were extracted. Using a semiautomated workflow, preoperative computed tomography head and neck angiograms were analyzed to determine the calcified plaque volume in distal common carotid artery and internal carotid artery plaques. Intraoperative digital subtraction angiograms were reviewed to calculate the percent residual stenosis post-intervention according to North American Symptomatic Carotid Endarterectomy Trial criteria. Peak systolic velocity and end-diastolic velocity were extracted from outpatient carotid duplex ultrasound examinations. Univariate logistic regression was performed to analyze the relationship of calcium volume percent and Vascular Quality Initiative lesion calcification to percent residual stenosis in completion angiograms. Kaplan-Meier analysis examined the relationship between calcium volume percent and in-stent stenosis over 36 months. RESULTS: One hundred ninety-seven carotid arteries were preliminarily examined. Predilation was performed in 87.4% of cases with a mean balloon diameter of 5.1 ± 0.7 mm and a mean stent diameter was 8.8 ± 1.1 mm. The mean calcium volume percent was 11.9 ± 12.4% and the mean percent residual stenosis was 16.1 ± 15.6%. Univariate logistic regression demonstrated a statistically significant difference between calcium volume percent and percent residual stenosis (odds ratio [OR], 1.324; 95% confidence interval [CI], 1.005-1.746; P = .046). Stratified by quartile, only the top 25% of calcified plaques (>18.7% calcification) demonstrated a statistically significant association with higher percent residual stenosis (OR, 2.532; 95% CI, 1.049-6.115; P =.039). There was no statistical significance with lesion calcification (OR, 1.298; 95% C,: 0.980-1.718; P = .069). A Kaplan-Meier analysis demonstrated a statistically significant increase in the rate of in-stent stenosis during a 36-month follow-up for lesions containing >8.2% calcium volume (P = .0069). CONCLUSIONS: A calcium volume percent of >18.7% was associated with a higher percent residual stenosis, and a calcium volume percent of >8.2% was associated with higher in-stent stenosis at 36 months. There was one clinically diagnosed stroke during the follow-up period, demonstrating the overall safety of the procedure.

RESUMEN

AIM: The application of high-resolution MS to antibody-drug conjugate (ADC) drug development may provide insight into their safety and efficacy. Quantification of unconjugated cytotoxic drug (payload) and characterization of drug-to-antibody ratio distribution were determined in plasma using orthogonal acceleration quadrupole-time-of-flight MS. RESULTS: Unconjugated payload quantification determined by quadrupole-time-of-flight-based MRM(highresolution) and triple quadrupole-based multiple reaction monitoring were comparable and achieved detection limits of 0.030 and 0.015 ng/ml, respectively. As determined by immunocapture and TOF-MS, drug-to-antibody ratio remained unchanged up to 3-weeks postdose for an ADC containing engineered glutamine linkers, but declined from four to three over 2 weeks in an ADC containing engineered cysteine linkers. CONCLUSION: The use of high-resolution MS in ADC drug discovery confirms its utility within the bioanalytical discipline.
