RESUMO
INTRODUCTION: Studies have shown that female physician trainees have an increased risk of burnout. We describe the current state of surgical and nonsurgical female trainee well-being and examine differences between surgical and nonsurgical specialties. METHODS: Survey responses were received from 1017 female identifying trainees from 26 graduate medical education institutions across the United States. These survey responses included demographic data and well-being measures. Specifically, burnout was assessed using the Maslach Burnout Inventory. Data were analyzed using Wilcoxon rank sum test, Fisher's exact test, and Pearson's Chi-squared test data with significance defined as a P < 0.05. This survey was reported in line with strengthening the reporting of cohort studies in surgery criteria. RESULTS: Nine-hundred ninety-nine participants completed the demographic and well-being section of the surveys and were included in analysis. Demographic data between the surgical versus nonsurgical group were similar, aside from surgeons being slightly older. Burnout was prevalent among all surveyed trainees with 63% scoring positive. Trainees also scored high in imposter syndrome and moral injury with low levels of self-compassion, although respondents also reported themselves flourishing. Surgical trainees scored higher than nonsurgical trainees in the personal accomplishment domain of burnout (P < 0.048). There was no difference between surgical and nonsurgical trainees in measures of the emotional exhaustion or depersonalization domains of burnout, or in impostor syndrome, self-compassion, moral injury, or flourishing. CONCLUSIONS: While personal accomplishment was noted to be higher in surgical trainees as compared to nonsurgical trainees, overall rates of burnout are high among both groups. Targeted interventions for well-being, such as coaching, can help decrease the levels of burnout experienced by female physician trainees and do not need to be specialty specific.

INTRODUCTION: Surgical cap attire plays an important role in creating a safe and sterile environment in procedural suites, thus the choice of reusable versus disposable caps has become an issue of much debate. Given the lack of evidence for differences in surgical site infection (SSI) risk between the two, selecting the cap option with a lower carbon footprint may reduce the environmental impact of surgical procedures. However, many institutions continue to recommend the use of disposable bouffant caps. METHODS: ISO-14044 guidelines were used to complete a process-based life cycle assessment to compare the environmental impact of disposable bouffant caps and reusable cotton caps, specifically focusing on CO2 equivalent (CO2e) emissions, water use and health impacts. RESULTS: Reusable cotton caps reduced CO2e emissions by 79% when compared to disposable bouffant caps (10 kg versus 49 kg CO2e) under the base model scenario with a similar reduction seen in disability-adjusted life years. However, cotton caps were found to be more water intensive than bouffant caps (67.56 L versus 12.66 L) with the majority of water use secondary to production or manufacturing. CONCLUSIONS: Reusable cotton caps have lower total lifetime CO2e emissions compared to disposable bouffant caps across multiple use scenarios. Given the lack of evidence suggesting a superior choice for surgical site infection prevention, guidelines should recommend reusable cotton caps to reduce the environmental impact of surgical procedures.

INTRODUCTION: Social determinants of health impact surgical outcomes. Characterization of surgeon understanding of social determinants of health is necessary prior to implementation of interventions to address patient needs. The study objective was to explore understanding, perceived importance, and practices regarding social determinants of health among surgeons. METHODS: Surgical residents and attending surgeons at a single academic medical center completed surveys regarding social determinants of health. We conducted semi-structured interviews to further explore understanding and perceived importance. A conceptual framework from the World Health Organization (WHO) Commission on Social Determinants of Health informed the thematic analysis. RESULTS: Survey response rate was 47.9% (n = 69, 44 residents [63.8%], 25 attendings [36.2%]). Respondents primarily reported good (n = 29, 42.0%) understanding of social determinants of health and perceived this understanding to be very important (n = 42, 60.9%). Documentation occurred seldom (n = 35, 50.7%), and referrals occurred seldom (n = 26, 37.7%) or never (n = 20, 29.0%). Residents reported a higher rate of prior training than attendings (95.5% versus 56.0%, P < 0.001). Ten interviews were conducted (six residents, four attendings). Residents demonstrated greater understanding of socioeconomic positions and hierarchies shaped by structural mechanisms than attendings. Both residents and attendings demonstrated understanding of intermediary determinants of health status and linked social determinants to impacting patients' health and well-being. Specific knowledge gaps were identified regarding underlying structural mechanisms including the social, economic, and political context that influence an individual's socioeconomic position. CONCLUSIONS: Self-reported understanding and importance of social determinants of health among surgeons were high. Interviews revealed gaps in understanding that may contribute to limited practices.

INTRODUCTION: The introduction of minimally invasive surgery (MIS) for repair of congenital diaphragmatic hernias (CDH) has reduced postoperative length of stay, postoperative opioid consumption, and provided a more esthetic repair. In adult abdominal surgery, minimally invasive techniques have been associated with decreased long-term rates of small bowel obstruction (SBO), although it is unclear if this benefit carries over into the pediatric population. Our objective was to evaluate the rates of SBO following open versus MIS CDH repair. MATERIAL AND METHODS: Infants who underwent CDH repair between 2010 and 2021 were identified using the PearlDiver Mariner database. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate time to SBO by surgical approach (MIS versus open) while adjusting for mesh use, patient sex, and length of stay. RESULTS: Of 1033 patients that underwent CDH repair, 258 (25.0%) underwent a minimally invasive approach. The overall rate of SBO was 7.5% (n = 77). Rate of SBO following MIS repair was lower than open repair at 1 y (0.8% versus 5.1%), 3 y, (2.3% versus 9.0%), and 5 y (4.4% versus 10.1%, P = 0.004). Following adjustment, the rate of SBO following MIS repair remained significantly lower than open repair (adjusted hazard ratio: 0.37, 95% confidence interval: 0.18, 0.79). CONCLUSIONS: Following CDH repair, long-term rates of SBO are lower among patients treated with MIS approaches. Long-term risk of SBO should be considered when selecting surgical approach for CDH patients.

BACKGROUND: The association of an individual's social determinants of health-related problems with surgical outcomes has not been well-characterized. The objective of this study was to determine whether documentation of social determinants of a health-related diagnosis code (Z code) is associated with postoperative outcomes. METHODS: This retrospective cohort study included surgical cases from a single institution's national surgical quality improvement program (NSQIP) clinical registry from October 2015 to December 2021. The primary predictor of interest was documentation of a Z code for social determinants of health-related problems. The primary outcome was 30-day postoperative morbidity. Secondary outcomes included postoperative length of stay, disposition, and 30-day postoperative mortality, reoperation, and readmission. Multivariable regression models were fit to evaluate the association between the documentation of a Z code and outcomes. RESULTS: Of 10,739 surgical cases, 348 patients (3.2%) had a documented social determinants of health-related Z code. In multivariable analysis, documentation of a Z code was associated with increased odds of morbidity (20.7% vs. 9.9%; adjusted odds ratio [aOR], 1.88; 95% confidence interval [CI], 1.39-2.53), length of stay (median, 3 vs. 1 day; incidence rate ratio, 1.49; 95% CI, 1.33-1.67), odds of disposition to a location other than home (11.3% vs. 3.9%; aOR, 2.86; 95% CI, 1.89-4.33), and odds of readmission (15.3% vs. 6.1%; aOR, 1.99; 95% CI, 1.45-2.73). CONCLUSIONS: Social determinants of health-related problems evaluated using Z codes were associated with worse postoperative outcomes. Improved documentation of social determinants of health-related problems among surgical patients may facilitate improved risk stratification, perioperative planning, and clinical outcomes.

BACKGROUND: Refinement of surgical preference cards may reduce waste from surgery. This study aimed to characterize surgeon perceptions and practices regarding preference card maintenance, identify barriers to updating preference cards, and explore whether opinions on environmental stewardship relate to preference card maintenance. METHODS: This was a mixed methods survey performed at a single tertiary academic medical center. Surgeons completed questions on accuracy, frequency of updates, and perceived environmental impact of their preference cards. Responses were compared between early career and mid-to late-career surgeons using Kruskal-Wallis, chi-squared, and Fisher's exact tests. RESULTS: The response rate was 46.4% (n = 89/192). Among respondents, 46.1% (n = 41/89) rarely or never updated preference cards. Nearly all (98.9%, n = 87/88) said some of their cases had unused items on their cards. Most (87.6%, n = 78/89) made updates via verbal requests. Unfamiliar processes (83.7%, n = 72/86) and effort required (64.0%, n = 55/86) were viewed as barriers to card maintenance. Most agreed that more frequent updates would reduce waste (80.5%, n = 70/87), but respondents did not feel knowledgeable about the environmental impact of items on their cards (62.1%, n = 54/87). Mid-to late-career surgeons were less likely to update their cards annually or more often compared to early career surgeons (18.9%, n = 7/37 vs. 57.1%, n = 24/42, p < 0.001). No other responses varied significantly between early career and mid-to late-career surgeons. CONCLUSIONS: Surgeons acknowledged the utility of preference card maintenance in environmental stewardship, but unfamiliar systems and perceived effort hindered preference card review. Greater attention to preference card maintenance would promote environmentally sustainable practices in surgery.
RESUMO
Accurate measurement of pneumothorax (PTX) size is necessary to guide clinical decision making; however, there is no consensus as to which method should be used in pediatric patients. This systematic review seeks to identify and evaluate the methods used to measure PTX size with CXR in pediatric patients. A systematic review of the literature through 2021 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was conducted using the following databases: Ovid/MEDLINE, Scopus, Cochrane Database of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar. Original research articles that included pediatric patients (< 18 years old) and outlined the PTX measurement method were included. 45 studies were identified and grouped by method (Kircher and Swartzel, Rhea, Light, Collins, Other) and societal guideline used. The most used method was Collins (n = 16; 35.6%). Only four (8.9%) studies compared validated methods. All found the Collins method to be accurate. Seven (15.6%) studies used a standard classification guideline and 3 (6.7%) compared guidelines and found significant disagreement between them. Pediatric-specific measurement guidelines for PTX are needed to establish consistency and uniformity in both research and clinical practice. Until there is a better method, the Collins method is preferred.

BACKGROUND: although being central for the biology and druggability of hormone-receptor positive, HER2 negative metastatic breast cancer (MBC), ESR1 and PIK3CA mutations are simplistically dichotomized as mutated or wild type in current clinical practice. METHODS: The study analyzed a multi-institutional cohort comprising 703 patients with luminal-like MBC characterized for circulating tumor DNA through next generation sequencing (NGS). Pathway classification was defined based on previous work (i.e., RTK, RAS, RAF, MEK, NRF2, ER, WNT, MYC, P53, cell cycle, notch, PI3K). Single nucleotide variations (SNVs) were annotated for their oncogenicity through OncoKB. Only pathogenic variants were included in the models. Associations among clinical characteristics, pathway classification, and ESR1/PIK3CA codon variants were explored. RESULTS: The results showed a differential pattern of associations for ESR1 and PIK3CA codon variants in terms of co-occurring pathway alterations patterns of metastatic dissemination, and prognosis. ESR1 537 was associated with SNVs in the ER and RAF pathways, CNVs in the MYC pathway and bone metastases, while ESR1 538 with SNVs in the cell cycle pathway and liver metastases. PIK3CA 1047 and 542 were associated with CNVs in the PI3K pathway and with bone metastases. CONCLUSIONS: The study demonstrated how ESR1 and PIK3CA codon variants, together with alterations in specific oncogenic pathways, can differentially impact the biology and clinical phenotype of luminal-like MBC. As novel endocrine therapy agents such as selective estrogen receptor degraders (SERDS) and PI3K inhibitors are being developed, these results highlight the pivotal role of ctDNA NGS to describe tumor evolution and optimize clinical decision making.

BACKGROUND: Pilonidal disease is classically treated with wide local excision, although a number of minimally invasive approaches are currently under investigation. We aimed to determine the safety and feasibility of laser ablation of pilonidal sinus disease. IMPACT OF INNOVATION: Laser ablation provides a minimally invasive means of obliterating pilonidal sinus tracts without a need for excessive tract dilation. Laser ablation can be performed more than once on the same patient if necessary. TECHNOLOGY MATERIALS AND METHODS: This technique uses the NeoV V1470 Diode Laser (neoLaser Ltd, Caesarea, Israel) with a 2-mm probe. We performed laser ablation in adults and pediatric patients. PRELIMINARY RESULTS: We performed 27 laser ablation procedures in 25 patients, with a median operative time of 30 minutes. Eighty percent of patients reported either no pain or mild pain at the 2-week postoperative visit. The median time to return to work or school was 3 days. Eighty-eight percent of patients reported being satisfied or very satisfied with the procedure at their most recent follow-up (median, 6 mo). Eighty-two percent of patients were healed at 6 months. CONCLUSIONS AND FUTURE DIRECTIONS: Laser ablation of pilonidal disease is safe and feasible. Patients experienced short recovery time and reported low levels of pain and high levels of satisfaction.

INTRODUCTION: The operating room (OR) is a major contributor to greenhouse gas emissions both nationally and globally. Successful implementation of quality improvement initiatives requires understanding of key stakeholders' perspectives of the issues at hand. Our aim was to explore surgical, anesthesia, and OR staff member perspectives on barriers and facilitators to reducing OR waste. MATERIALS AND METHODS: Identified stakeholders from a single academic medical center were interviewed to identify important barriers and facilitators to reducing surgical waste. Two team members with qualitative research experience used deductive logic guided by the Theoretical Domains Framework of behavior change to identify themes within transcripts. RESULTS: Nineteen participants including surgeons (n = 3, 15.8%), surgical residents (n = 5, 26.3%), an anesthesiologist (n = 1, 5.3%), anesthesia residents (n = 2, 10.5%), nurse anesthetists (n = 2, 10.5%), nurses (n = 5, 26.3%), and a surgical technologist (n = 1, 5.3%) were interviewed. Twelve of the 14 themes within the Theoretical Domains Framework were discovered in transcripts. Barriers within these themes included lack of resources to pursue environmental sustainability in the OR and the necessity of maintaining sterility for patient safety. Facilitators included emphasizing surgeon leadership within the OR to reduce unused supplies and spreading awareness of the environmental and economic impact of surgical waste. CONCLUSIONS: Interviewed stakeholders were able to identify areas where improvements around surgical waste reduction and management could be made at the institution by describing barriers and facilitators to sustainability-driven interventions. Future surgical waste reduction initiatives at this institution will be guided by these important perspectives.
RESUMO
INTRODUCTION: Disparities in the delivery of pediatric surgical care exist for racial and ethnic minority groups. Utilization of same-day discharge (SDD) following appendectomy for acute, uncomplicated appendicitis is increasing; however, rates among diverse populations have not been explored to evaluate equitable care delivery and healthcare utilization. Our objective was to determine whether race and ethnicity are associated with rates of SDD and postdischarge healthcare utilization. We hypothesized that racial and ethnic minority groups would have lower rates of SDD. METHODS: This retrospective cohort study used data from the 2015-2019 American College of Surgeons National Surgical Quality Improvement Program-Pediatric clinical registry and included children who underwent appendectomy. Patients with complicated appendicitis were excluded. Primary exposure was racial or ethnic group. The primary outcome was SDD, and secondary outcomes included postdischarge emergency department visits and hospital readmissions. RESULTS: Of 37,579 simple appendicitis patients, SDD after appendectomy occurred in 10,012 (26.6%). On multivariable analysis, Black or African American race was associated with lower likelihood of SDD (adjusted odds ratio [aOR]: 0.85; 95% confidence interval [95% CI]:0.79-0.92; P < 0.0001). Hispanic ethnicity was associated with higher likelihood of SDD (aOR: 1.19; 95% CI: 1.12-1.25; P < 0.0001). Likelihood of postoperative emergency department visits was higher in Black or African American patients (aOR: 1.36; 95% CI: 1.14-1.62; P < 0.001) and Hispanic patients (aOR: 1.37; 95% CI: 1.12-1.58; P < 0.0001). Hospital readmission rates were similar across groups. CONCLUSIONS: Rates of SDD following appendectomy vary among racial and ethnic groups. Interventions to achieve equitable healthcare delivery including SDD after appendectomy are needed.

PURPOSE: Fundoplication is frequently used in children with neurologic impairment even in the absence of reflux due to concerns for future gastric feeding intolerance, but supporting data are lacking. We aimed to determine the incidence of secondary antireflux procedures (fundoplication or gastrojejunostomy (GJ)) post gastrostomy tube (GT) placement in children with and without neurologic impairment. METHODS: Children under 18 undergoing a GT placement without fundoplication between 2010 and 2020 were identified utilizing the PearlDiver Mariner national patient claims database. Children with a diagnosis of cerebral palsy or a degenerative neurologic disease were identified and compared to children without these diagnoses. The incidence of delayed fundoplication or conversion to GJ were compared utilizing Kaplan-Meier and Cox proportional hazards regression analyses. RESULTS: A total of 14,965 children underwent GT placement, of which 3712 (24.8%) had a diagnosis of neurologic impairment. The rate of concomitant fundoplication was significantly higher among children with a diagnosis of neurologic impairment as compared to those without (9.3% vs 6.4%, p < 0.001). While children with neurologic impairment had a significantly higher rate of fundoplication or GJ conversion at 5 years compared to children without (12.6% [95% confidence interval (CI): 11.4%-13.8%] vs 8.6% [95% CI 8.0%-9.2%], p < 0.001), the overall incidence remained low. CONCLUSION: Although children with neurologic impairment have a higher rate of requiring an antireflux procedure or GJ conversion than other children, the overall rate remains less than 15%. Fundoplication should not be utilized in children without clinical reflux on the basis of neurologic impairment alone.

INTRODUCTION: Recurrent primary spontaneous pneumothorax (PSP) is often managed with a wedge resection (or blebectomy) and either pleurectomy or pleurodesis. There is a conflicting data regarding which approach is superior to reduce recurrence. Our objective is to evaluate the long-term recurrence rates following pleurectomy versus mechanical pleurodesis for recurrent PSP. METHODS: The PearlDiver Mariner Patient Claims Database was queried for patients aged 10-25 who were presented with PSP and underwent either pleurectomy or mechanical pleurodesis between 2010 and 2020. The primary outcome was recurrence and secondary outcomes included 30-day opioid prescriptions, pain diagnoses, and reimbursement. Kaplan-Meier analysis and Cox proportional hazards regression models were used with adjustment for age and sex. RESULTS: Of 18,955 patients presenting with PSP, 5.1% (n = 968) were managed operatively with either pleurectomy (18.3%, n = 177) or mechanical pleurodesis (81.7%, n = 791). There was no difference in the rate of recurrence between pleurectomy and mechanical pleurodesis (5-year risk of recurrence: 25.8% versus 26.5%, adjusted hazard ratio (HR) = 1.12 [95% confidence interval (CI): 0.79, 1.58]). Furthermore, there was no difference in rate of outpatient opioid prescription (49.2% versus 52.8%, P = 0.58) or pain diagnoses (22.0% versus 22.8%, P = 0.46) between pleurectomy and mechanical pleurodesis, respectively. The median reimbursement was higher following pleurectomy as compared to mechanical pleurodesis ($14,040 versus $5,811, P = 0.02). CONCLUSIONS: There is no significant difference in recurrence based on type of procedure performed for recurrent primary spontaneous pneumothorax. However, reimbursement is higher following pleurectomy. Given the similar outcomes but higher cost, we recommend mechanical pleurodesis over pleurectomy for recurrent PSP.

PURPOSE: Meaningful comparison of mutational landscapes across ethnic groups requires the use of standardized platform technology. We have used a harmonized NGS-based liquid biopsy assay to explore the differential genomic landscape of patients with initially hormone receptor-positive (HR+), HER2-negative MBC of first line metastasis or primary Stage IV at diagnosis from the United States (US) and China (CN). METHODS: Plasma circulating tumor DNA (ctDNA) from 27 US patients and 65 CN patients was sequenced using the harmonized CLIA-certified, 152-gene PredicineCare™ liquid biopsy assay. Kaplan-Meier survival analysis was performed to analyze the correlation between genomic alterations and progression-free survival (PFS), and p-values were calculated using the log-rank test. RESULTS: All patients in the CN cohort received chemotherapy and/or hormonal therapy, while 85.2% (23/27) patients in the US cohort received hormonal therapy plus CDK4/6 inhibitors. Mutations were detected in 23 of 27 (85%) US patients and 54 of 65 (83%) CN patients. The prevalence of AKT1 (P = 0.008) and CDH1 (P = 0.021) alterations were both higher in the US vs. CN cohort. In addition, FGFR1 amplification were more frequent in the CN vs. US cohort (P = 0.048). PTEN deletions (P = 0.03) and ESR1 alterations (P = 0.02) were associated with shorter PFS in the CN cohort, neither of these associations were observed in the US cohort. Interestingly, a reduced association between PTEN deletion and PFS was observed in patients receiving CDK4/6 inhibitor treatment. CONCLUSION: The differential prevalence of ctDNA-based alterations such as FGFR1, AKT1, and CDH1 was observed in initially HR+/HER2- MBC patients in the US vs. CN. In addition, the association of PTEN deletions with shorter PFS was found in the CN but not the US cohort. The differential genomic landscapes across the two ethnic groups may reflect biologic differences and clinical implications.

BACKGROUND: Clinical and genomic data from patients with early-stage breast cancer suggest more aggressive disease in premenopausal women. However, the association between age, disease course, and molecular profile from liquid biopsy in metastatic breast cancer (MBC) is not well characterized. METHODS: Patients were classified as premenopausal (< 45 years), perimenopausal (45-55 years), or postmenopausal (> 55 years). Cohort 1 consisted of patients with MBC who consented for prospective serial evaluation of circulating tumor cells (CTCs) using CellSearch™. Cohort 2 included patients who, as part of routine care, had circulating tumor DNA (ctDNA) sequenced by the Guardant360™ assay. Clinicopathologic data were collected from retrospective review to compare disease features between premenopausal and postmenopausal women. RESULTS: Premenopausal women represented 26% of 138 patients in Cohort 1 and 21% of 253 patients in Cohort 2. In Cohort 1, younger patients had a shorter time to metastases and a higher prevalence of lung and brain metastases. Overall, there were similar rates of ≥ 5 CTCs/7.5 mL, HER2 + CTC expression, and CTC clusters between pre- and postmenopausal women. However, for those with triple negative breast cancer, premenopausal women had a higher proportion of ≥ 5 CTCs/7.5 mL. In Cohort 2, premenopausal women had a higher incidence of FGFR1 (OR 2.75, p = 0.022) and CCND2 (OR 6.91, p = 0.024) alterations. There was no difference in the ctDNA mutant allele frequency or the number of detected alterations between these age groups. CONCLUSIONS: Our data reveal that premenopausal women diagnosed with MBC have unique clinical, pathologic, and molecular features when compared to their postmenopausal counterparts. Our results highlight FGFR1 inhibitors as potential therapeutics of particular interest among premenopausal women.

BACKGROUND: Meckel's Diverticulum (MD) is a common congenital anomaly accounting for half of pediatric gastrointestinal bleeds. No large-scale studies exist comparing open and laparoscopic surgery and conversion rates remain high. We sought to compare postoperative outcomes associated with each approach and to determine risk factors for conversion. MATERIALS AND METHODS: NSQIP-Pediatric was used to identify patients who underwent a MD resection from 2012 to 2018. Outcomes between patients treated with a laparoscopic versus open versus laparoscopic converted to open (LCO) surgery were compared. Chi-square tests and adjusted logistic regression analysis were used to determine significance and factors associated with conversion. RESULTS: Six hundred eighty-one patients were identified, 295 (43.3%) underwent open, 267 (39.2%) laparoscopic, and 119 (17.5%) LCO resection. Patients undergoing laparoscopic compared to open procedures had shorter length of stay (LOS; 3 versus 4, P= 0.009), and similar morbidities (10.5% versus 16.6%, P= 0.164) and operative times (71.6 versus 76.6 mins, P= 0.449) on adjusted analysis. Patients with LCO compared to open procedures had similar LOS (4 versus 4, P= 0.334) and morbidities (14.3% versus 16.6%, P= 0.358), but longer operative times (90.1 versus 76.6 mins, P= 0.002) on adjusted analysis. Patients with laparoscopic and LCO procedures had fewer unplanned intubations compared to open procedures (0.0% versus 0.0% versus 2.4%, P= 0.011) and lower mortality (0.0% versus 0.0% versus 1.7%, P= 0.046) on univariate analysis. CONCLUSIONS: Laparoscopic MD resection has shorter LOS and similar complications and operative time compared to an open approach while LCO resection increases operative time but not LOS or morbidities.

BACKGROUND: Surgical simulation-based training (SBT) can increase resident confidence and improve performance. SBT in pediatric surgery is in its infancy and often geared toward training pediatric surgery fellows. Since case volume for various pediatric surgery-specific procedures can be low based on the rarity of the pathology involved and the level of care provided by the institution, our aim was to create a pediatric surgery simulation-based curriculum for general surgery residents to address this need. MATERIALS AND METHODS: We performed an institutional needs assessment consisting of 4 pediatric surgeons' and 28 general surgery residents' confidence in resident ability to independently perform pediatric surgery-specific tasks and procedures using a Likert-scaled survey. These included the placement of a silastic silo for gastroschisis, a percutaneous drain for perforated necrotizing enterocolitis, and completion of a laparoscopic pyloromyotomy for pyloric stenosis. Models simulating these pathologies and curriculum for performing each procedure were generated. RESULTS: We successfully created a model and SBT curriculum to teach general surgery residents how to place a silastic silo for patients with gastroschisis, a percutaneous drain for patients with perforated necrotizing enterocolitis, and how to complete a laparoscopic pyloromyotomy for patients with pyloric stenosis. These were deemed high fidelity models based on a survey of our pediatric surgeons. CONCLUSIONS: We created a pediatric surgery SBT curriculum for general surgery residents, which can be used to supplement learning of various high-acuity, low-occurrence procedures. Assessment of residents and validation of scores is underway.

Breast cancer is the most common malignancy in young women worldwide, accounting for an estimated 30% of new cancer diagnoses and 25% of cancer deaths. Approximately two thirds of young women with breast cancer have hormone receptor-positive (HR+)/human epidermal growth receptor 2-negative (HER2-) tumors. Numerous studies, primarily in early-stage breast cancer, have demonstrated that young age is an independent risk factor for more aggressive disease and worse outcomes. Although more limited data are available regarding outcomes in young patients with advanced disease, these age-related disparities suggest that breast cancer in premenopausal women has distinct clinicopathologic and molecular features that can impact treatment outcomes. Until recently, limited data were available on the intrinsic molecular subtypes and genetics of young patients with HR+/HER2- metastatic breast cancer (mBC). In this review, we explore insights into the clinical and pathologic features of HR+/HER2- mBC in younger women derived from recent clinical trials of the cyclin-dependent kinase 4/6 inhibitors palbociclib (PALOMA-3), ribociclib (MONALEESA-7), and abemaciclib (MONARCH 2) and the implications of these findings for clinical practice, guideline development, and future research. IMPLICATIONS FOR PRACTICE: This review provides clinicians with an overview of emerging data on the unique clinicopathologic and molecular features of hormone receptor-positive/human epidermal growth receptor 2-negative metastatic breast cancer (mBC) in premenopausal women, summarizes findings from the most recent clinical trials of endocrine-based treatment in this patient population, and explores the implications of these findings for clinical practice, guideline development, and future research. Improved understanding of the key factors influencing disease course and treatment response in premenopausal patients with mBC may lead to more timely incorporation of evidence-based treatment approaches, thereby improving patient care and outcomes.

PURPOSE: Liquid biopsies, including circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs), can be used to understand disease prognosis, tumor heterogeneity, and dynamic response to treatment in metastatic breast cancer (MBC). We explored a novel, 180-gene ctDNA panel and the association of this platform with CTCs and CTC clusters. METHODS: A total of 40 samples from 22 patients with MBC were included in the study. For the primary analysis, all patients had ctDNA sequencing using the PredicinePLUS™ platform. CTCs and CTC clusters were examined using the CellSearch™ System. Clinical and pathological variables were reported using descriptive analyses. Associations between CTC count and specific genomic alterations were tested using the Mann-Whitney U test. RESULTS: Of 43 sequenced patients, 40 (93%) had at least one detectable genomic alteration with a median of 6 (range 1-22). Fifty-seven different genes were altered, and the landscape of genomic alterations was representative of MBC, including the commonly encountered alterations TP53, PTEN, PIK3CA, ATM, BRCA1, CCND1, ESR1, and MYC. In patients with predominantly hormone-receptor-positive MBC, the number of CTCs was significantly associated with alterations in ESR1 (P < 0.005), GATA3 (P < 0.05), CDH1 (P < 0.0005), and CCND1 (P < 0.05) (Mann-Whitney U test). Thirty-six percent of patients had CTC clusters, which were associated with alterations in CDH1, CCND1, and BRCA1 (all P < 0.05, Mann-Whitney U test). In an independent validation cohort, CTC enumeration confirmed significant associations with ESR1 and GATA3, while CTC clusters were significantly associated with CDH1. CONCLUSIONS: We report on a novel ctDNA platform that detected genomic alterations in the vast majority of tested patients, further indicating potential clinical utility for capturing disease heterogeneity and for disease monitoring. Detection of CTCs and CTC clusters was associated with particular genomic profiles.

OPINION STATEMENT: Precision Medicine is gaining momentum as the future gold standard healthcare strategy as it enables treatment optimization and consequently a potential improvement for quality of life and survival. This paradigm shift was possible thanks to new high-throughput genomics technologies, which provide prognostic and predictive information on tumor biology and potential treatment options, as standard pathological procedures are unable to capture both spatial and temporal tumor heterogeneity. As a result of decreasing costs, both solid and liquid-based genomics have an increasingly important role in clinical trials' screening procedures and are gradually being incorporated into clinical practice. Notwithstanding the great potential, its clinical utility is still a matter of debate and clinicians need to be aware of caveats in interpreting resulting data.
