INTRODUCTION: Diversity, Equity, and Inclusion (DEI) are concepts common in surgery. However, these can be difficult to define, and what constitutes DEI can be vague. Closing this knowledge gap, particularly within pediatric surgery, would be helpful to understand the views and needs of current surgeons. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, views on what constitutes diversity as well as questions on how DEI is handled within APSA and definitions of common DEI terms. RESULTS: Of 11 possible diversity measures, members agreed that a median of 9 (IQR 7-11) counted towards diversity. The most common being race and ethnicity (98%), gender (96%), sexual orientation (93%), religion (92%), age (91%), and disability (90%). On a 5-point Likert scale, the median response was 4 or greater on questions regarding how APSA handles issues related to DEI. However, members who identify as black were less likely to score in favor of APSA, and members identifying as women were more likely to rank higher importance of DEI initiatives. We also captured subjective responses on DEI terminology. CONCLUSION: Respondents had broad definitions of diversity. There is support for further DEI initiatives and how APSA handles DEI, however this perception differs based on identities. There is significant variability in beliefs and views regarding DEI definitions and understanding this is helpful for the organization moving forward. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Original Research.

INTRODUCTION: Bias and discrimination remain pervasive in the medical field and increase the risk of burnout, mental health disorders, and medical errors. The experiences of APSA members with bias and discrimination are unknown, therefore the APSA committee on Diversity, Equity and Inclusion conducted a survey to characterize the prevalence of bias and discrimination. METHODS: 1558 APSA members were sent an anonymous survey, of which 423 (27%) responded. Respondents were asked about their demographics, knowledge of implicit bias, and experience of bias and discrimination within their primary workplace, APSA, and APSA committees. Data were analyzed using Fisher's Exact test, Kruskal-Wallis test, and multivariable logistic regression as appropriate with significance defined as p<0.05. RESULTS: Discrimination was reported across all levels of practice, academic appointments, race, ethnicity, and gender identities. On multivariable analysis, surgical trainees (OR 3.6) as well as Asian American and Pacific Islander (OR 4.8), Black (OR 5.2), Hispanic (OR 8.2) and women (OR 8.7) surgeons were more likely to experience bias and discrimination in the workplace. Community practice surgeons were more likely to experience discrimination within APSA committees (OR 3.6). Members identifying as Asian (OR 0.4), or women (OR 0.6) were less likely to express comfort reporting instances of bias and discrimination. CONCLUSION: Workplace discrimination exists across all training levels, academic appointments, and racial and gender identities. Trainees and racial- and gender-minority surgeons report disproportionately high prevalence of bias and discrimination. Improving reporting mechanisms and implicit bias training are possible initiatives in addressing these findings.

INTRODUCTION: There are existing healthcare disparities in pediatric surgery today. Identity and racial incongruity between patients and providers contribute to systemic healthcare inequities and negatively impacts health outcomes of minoritized populations. Understanding the current demographics of the American Pediatric Surgical Association and therefore the cognitive diversity represented will help inform how best to strategically build the organization to optimize disparity solutions and improve patient care. METHODS: 1558 APSA members were sent an anonymous electronic survey. Comparative data was collected from the US Census Bureau and the Association of American Medical Colleges. Results were analyzed using standard statistical tests. RESULTS: Of 423 respondents (response rate 27%), the race and ethnicity composition were 68% non Hispanic White, 12% Asian American and Pacific Islander, 6% Hispanic, 5% multiracial, and 4% Black/African American. Respondents were 35% women, 63% men, and 1% transgender, androgyne, or uncertain. Distribution of sexual identity was 97% heterosexual and 3% LGBTQIA. Religious identity was 50% Christian, 22% Agnostic/Atheist, 11% Jewish, 3% Hindu, and 2% Muslim. 32% of respondents were first-generation Americans. Twenty-four different primary languages were spoken, and 46% of respondents were conversational in a second language. These findings differ in meaningful ways from the overall American population and from the population of matriculants in American medical schools. CONCLUSION: There are substantial differences in the racial, gender, and sexual identity composition of APSA members compared with the overall population in the United States. To achieve excellence in patient care and innovate solutions to existing disparities, representation, particularly in leadership is essential. TYPE OF STUDY: Survey; original research. LEVEL OF EVIDENCE: Level IV.

A 69-year-old Native American female with a past medical history of end-stage renal disease presented to our rural outpatient dialysis access center. One and a half years prior, the patient's arteriovenous fistula was banded due to venous steal syndrome and now demonstrated an abnormal bruit with decreased blood flow during dialysis. On arteriogram, she was found to have a 90% narrowing of her previously banded cephalic vein along with stenosis of the arterial anastomosis and subclavian vein. Balloon angioplasty was performed on the subclavian vein stenosis, and the banded cephalic vein was ruptured. However, the arterial anastomosis stenosis was left untreated due to the patient's previous venous steal syndrome.

A 42-year-old female with a past medical history of femoral facial syndrome (FFS) and years of gastroesophageal reflux disease presented to our clinic with symptoms of dysphagia and iron deficiency anemia. On upper endoscopy, esophageal stricture and adenocarcinoma were detected. Unfortunately, the patient developed coronavirus disease 2019 (COVID-19) multi-organ failure prior to cancer treatment and died with dignity after choosing comfort care measures. To the best of our knowledge, we report the first case of FFS in an adult patient. This case also uniquely highlights the rare gastrointestinal manifestations of FFS.
RÉSUMÉ
Despite progress, diversity and minority representation within the pediatric surgery workforce still does not match the expansive backgrounds of the patients we treat. The problem stems from underrepresentation of minority populations at every step along the pediatric surgery training pathway. Strategies aimed at improving diversity and representation in medical school, general surgery residencies, and ultimately pediatric surgery fellowship are necessary to assemble a more diverse pool of pediatric surgeons. The aim of this paper is to review the current demographic make-up of medical and surgical specialties, highlight the value of diversity, and provide evidence-based strategies for increasing minority representation throughout the pediatric surgery pathway. Future patients will be better served with a more representative pediatric surgery workforce.

A dropped appendicolith is a well-known complication of laparoscopic appendectomy that may occur because of stone expulsion from the appendix, before or during surgery, and typically manifests as a focal, subcentimeter area of high attenuation with or without associated abscess. Dropped appendicoliths may act as niduses for infection and may result in the future development of abscess formation. We report the case of a 10-year-old pediatric patient who developed 2 perihepatic abscesses caused by 2 appendicoliths that were inadvertently dropped during laparoscopic surgery.
RÉSUMÉ
ssDNA, which is involved in numerous aspects of chromosome biology, is managed by a suite of proteins with tailored activities. The majority of these proteins bind ssDNA indiscriminately, exhibiting little apparent sequence preference. However, there are several notable exceptions, including the Saccharomyces cerevisiae Cdc13 protein, which is vital for yeast telomere maintenance. Cdc13 is one of the tightest known binders of ssDNA and is specific for G-rich telomeric sequences. To investigate how these two different biochemical features, affinity and specificity, contribute to function, we created an unbiased panel of alanine mutations across the Cdc13 DNA-binding interface, including several aromatic amino acids that play critical roles in binding activity. A subset of mutant proteins exhibited significant loss in affinity in vitro that, as expected, conferred a profound loss of viability in vivo. Unexpectedly, a second category of mutant proteins displayed an increase in specificity, manifested as an inability to accommodate changes in ssDNA sequence. Yeast strains with specificity-enhanced mutations displayed a gradient of viability in vivo that paralleled the loss in sequence tolerance in vitro, arguing that binding specificity can be fine-tuned to ensure optimal function. We propose that DNA binding by Cdc13 employs a highly cooperative interface whereby sequence diversity is accommodated through plastic binding modes. This suggests that sequence specificity is not a binary choice but rather is a continuum. Even in proteins that are thought to be specific nucleic acid binders, sequence tolerance through the utilization of multiple binding modes may be a broader phenomenon than previously appreciated.

Potential anticancer activity of 16 azetidin-2-one derivatives was evaluated showing that compound 6 [N-(p-methoxy-phenyl)-2-(p-methyl-phenyl)-3-phenoxy-azetidin-2-one] presented cytotoxic activity in SiHa cells and B16F10 cells. The caspase-3 assay in B16F10 cells displayed that azetidin-2-one derivatives induce apoptosis. Microarray and molecular analysis showed that compound 6 was involved on specific gene overexpression of cytoskeleton regulation and apoptosis due to the inhibition of some cell cycle genes. From the 16 derivatives, compound 6 showed the highest selectivity to neoplastic cells, it was an inducer of apoptosis, and according to an in silico analysis of chemical interactions with colchicine binding site of human α/ß-tubulin, the mechanism of action could be a molecular interaction involving the amino acids outlining such binding site.
RÉSUMÉ
BACKGROUND: Accurate clinical documentation (CD) is necessary for many aspects of modern health care, including excellent communication, quality metrics reporting, and legal documentation. New requirements have mandated adoption of ICD-10-CM coding systems, adding another layer of complexity to CD. A clinical documentation improvement (CDI) and ICD-10 training program was created for health care providers in our academic surgery department. We aimed to assess the impact of our CDI curriculum by comparing quality metrics, coding, and reimbursement before and after implementation of our CDI program. STUDY DESIGN: A CDI/ICD-10 training curriculum was instituted in September 2014 for all members of our university surgery department. The curriculum consisted of didactic lectures, 1-on-1 provider training, case reviews, e-learning modules, and CD queries from nurse CDI staff and hospital coders. Outcomes parameters included monthly documentation completion rates, severity of illness (SOI), risk of mortality (ROM), case-mix index (CMI), all-payer refined diagnosis-related groups (APR-DRG), and Surgical Care Improvement Program (SCIP) metrics. Financial gain from responses to CDI queries was determined retrospectively. RESULTS: Surgery department delinquent documentation decreased by 85% after CDI implementation. Compliance with SCIP measures improved from 85% to 97%. Significant increases in surgical SOI, ROM, CMI, and APR-DRG (all p < 0.01) were found after CDI/ICD-10 training implementation. Provider responses to CDI queries resulted in an estimated $4,672,786 increase in charges. CONCLUSIONS: Clinical documentation improvement/ICD-10 training in an academic surgery department is an effective method to improve documentation rates, increase the hospital estimated reimbursement based on more accurate CD, and provide better compliance with surgical quality measures.

BACKGROUND: Intestinal barrier dysfunction has been implicated in necrotizing enterocolitis (NEC), but has not been directly measured in human NEC. METHODS: Small intestines removed during surgery were immediately mounted in an Ussing chamber. mRNA expression of tight junction (TJ) proteins was measured with RT-PCR. RESULTS: Fifteen infants were included, 5 with NEC and 10 with other diagnoses. Average transepithelial resistance (TER) was 11.61±1.65Ω/cm2 in NEC specimens, 23.36±1.48Ω/cm2 at resection margin, and 46.48±5.65Ω/cm2 in controls. Average flux of permeability marker mannitol was 0.23±0.06µMol/cm2 per h in NEC, 0.04±0.01 µMol/cm2 per h at resection margin, and 0.017±0.004 µMol/cm2 per h in control tissue (p<0.05). RT-PCR analysis showed marked decrease in mRNA expression of a TJ protein occludin in NEC affected tissue (p<0.03 vs. control). Additionally, mRNA expression of myosin light chain kinase (MLCK), an important regulator of TJ permeability, was increased in NEC specimens. CONCLUSION: These studies show for the first time that NEC intestinal tissue have increased intestinal permeability, even at grossly healthy-appearing resection areas. The increase in intestinal permeability in NEC appeared to be related in part to a decrease in occludin and an increase in MLCK expression. LEVEL OF EVIDENCE: Level 2.

We report a case of middle cerebral artery stroke with heterozygosity for 2 separate hypercoagulable conditions following repair of an H-type tracheoesophageal fistula (TEF) in an infant. Neonatal stroke is rare, occurring in 1 in 4000 births annually in the United States. Stroke after pediatric surgery occurs in approximately 0.05% of patients. Etiologies of stroke in neonates include cardiac, hematologic, vascular, traumatic, metabolic, pharmacologic, infectious, and hypoxemic insults. Thrombophilia has been described in 42% to 78% of neonates with neonatal stroke. Stroke after repair of an H-type TEF has not been reported as a postoperative complication. Manipulation of the carotid artery during this operation is presumed to have contributed to a thromboembolic event in this infant with a hypercoagulable state. Whereas preoperative workup may not be indicated due to the low prevalence of neonatal stroke, workup for a congenital hypercoaguable condition may be considered in infants with stroke as a postoperative complication. This report provides a concise review of the etiology and treatment of stroke and hypercoagulable states in neonates as well as presents the case of a previously undescribed complication of repair of an H-type TEF.

OBJECTIVE: Cardiac involvement in SSc is characterized by myocardial fibrosis, arrhythmias and pericarditis. Prevalence studies have shown variable results. The objective of this study was to determine the prevalence of cardiac involvement in SSc patients using the non-invasive, highly sensitive diagnostic methods of cardiac MRI and coronary angiotomography. METHODS: We included 62 SSc patients and excluded those with heart disease prior to the onset of SSc, renal failure, diabetes mellitus, hyperlipidaemia, arterial hypertension, untreated thyroid disease, cor pulmonale, pregnancy or contraindications to performing cardiac MRI. All underwent clinical and laboratory evaluation, ECG, coronary angiotomography and cardiac MRI. RESULTS: The prevalence of myocardial fibrosis was 45% and was higher in dcSSc (59%) than in lcSSc patients (33%; P = 0.04). The mean left ventricular ejection fraction (LVEF) was lower in patients with myocardial fibrosis (56%) than in those without fibrosis (63%; P = 0.0009); myocardial fibrosis on MRI was more frequent in the basal-septal segments of the LV. Seventy-nine per cent of patients had subendocardial perfusion defects and these were associated with higher ultrasensitive serum CRP values. There was no association of myocardial fibrosis or microvascular damage with atherosclerosis. CONCLUSION: The prevalence of myocardial fibrosis on MRI attributable to SSc is 45%, is more frequent and severe in dcSSc patients, is associated with lower LVEF and affects mainly basal LV walls. Microvascular damage in SSc is common and is associated with elevated ultrasensitive CRP levels. Cardiac damage due to SSc is not associated with coronary artery disease.

Failed regeneration of costal cartilage after open repair of pectus chest wall deformities can result in a floating sternum. A floating sternum can be repaired by insertion of a rib graft between the rib and sternum, and stabilization with a metal strut. The metal implant is usually removed with a second operation. We report use of bioabsorbable struts to stabilize rib grafts during repair of a floating sternum in an 18-year-old male with a failed open repair of pectus carinatum. He had an uncomplicated peri-operative course. One year later, the sternum had a normal appearance and was sturdy. A second operation for removal of hardware was not necessary.
