The rise of β-lactam resistance necessitates new strategies to combat bacterial infections. We purposefully engineered the β-lactam prodrug AcephPT to exploit β-lactamase activity to selectively suppress resistant bacteria producing extended-spectrum-β-lactamases (ESBLs). Selective targeting of resistant bacteria requires avoiding interaction with penicillin-binding proteins, the conventional targets of β-lactam antibiotics, while maintaining recognition by ESBLs to activate AcephPT only in resistant cells.

Background: No benchmarking data exist to aid hospitals in identifying and prioritizing opportunities for infection prevention or antimicrobial stewardship in children with complicated appendicitis.
Methods: This was a multicenter cohort study using National Surgical Quality Improvement Program-Pediatric data from 16 hospitals participating in a regional research consortium, augmented with antibiotic utilization data obtained through supplemental chart review.
Importance: Gangrenous, suppurative, and exudative (GSE) findings have been associated with increased surgical site infection (SSI) risk and resource use in children with nonperforated appendicitis. Establishing the role for postoperative antibiotics may have important implications for infection prevention and antimicrobial stewardship.
Objective: To compare SSI rates in children with nonperforated appendicitis with GSE findings who did and did not receive postoperative antibiotics.

Background/purpose: Cephalosporins are considered safe and first-line prophylaxis in children with non-severe penicillin allergies. However, use of second-line agents is common and is primarily driven by poor allergic response documentation and misunderstanding of cross-reactivity risk. The goal of this project was to improve compliance with cephalosporin prophylaxis through improved documentation and targeted educational efforts.

Palliative care is underutilized in this vulnerable population. We described kidney transplant clinicians' perceptions of palliative care to delineate their perceived barriers to and facilitators of providing palliative care to this population.

Methods: A multicenter retrospective cohort analysis of children undergoing appendectomy for suspected appendicitis was performed using data from the 2016-2021 NSQIP-Pediatric Appendectomy Targeted Public Use Files. Multivariable regression was used to evaluate the influence of year, age, sex, and WBC count on NA rate, and to generate rate estimates for NA based on different combinations of demographic characteristics and WBC profiles.
Establishing a standardized and comprehensive framework for defining surgical quality is essential for meaningful performance measurement and process improvement efforts. The goal of this chapter is to provide a conceptual framework for defining surgical quality based on the perspectives of relevant stakeholders, and to identify infrastructure and care processes necessary for the delivery of high-quality surgical care. Central to this framework are the complementary approaches for quality assessment as outlined by the Institute of Medicine and Donabedian paradigms, and how these should be used together to develop a robust and granular taxonomy of quality constructs relevant to all surgical conditions.
View Article and Find Full Text PDFBackground: The objective of this study was to quantify prophylaxis misutilization to identify high-priority procedures for improved stewardship and SSI prevention.
Methods: This was a multicenter analysis including 90 hospitals participating in the NSQIP-Pediatric Antibiotic Prophylaxis Collaborative from 6/2019 to 6/2020. Prophylaxis data were collected from all hospitals and misutilization measures were developed from consensus guidelines.
Importance: Use of postoperative antimicrobial prophylaxis is common in pediatric surgery despite consensus guidelines recommending discontinuation following incision closure. The association between postoperative prophylaxis use and surgical site infection (SSI) in children undergoing surgical procedures remains poorly characterized.
Objective: To evaluate whether use of postoperative surgical prophylaxis is correlated with SSI rates in children undergoing nonemergent surgery.

Objective: To quantify procedure-level inappropriate antimicrobial prophylaxis utilization as a strategy to identify high-priority targets for stewardship efforts in pediatric surgery.
Background: Little data exist to guide the prioritization of antibiotic stewardship efforts as they relate to prophylaxis utilization in pediatric surgery.
Methods: This was a retrospective cohort analysis of children undergoing elective surgical procedures at 52 children's hospitals from October 2015 to December 2019 using the Pediatric Health Information System database.
Introduction: Gender disparities in resident operative experience have been described; however, their etiology is poorly understood, and racial/ethnic disparities have not been explored. This study investigated the relationship between gender, race/ethnicity, and surgery resident case volumes.
Materials And Methods: A retrospective analysis of graduating general surgery resident case logs (2010-2020) at an academic medical center was performed.
Importance: The clinical significance of gangrenous, suppurative, or exudative (GSE) findings is poorly characterized in children with nonperforated appendicitis.
Objective: To evaluate whether GSE findings in children with nonperforated appendicitis are associated with increased risk of surgical site infections and resource utilization.
Design, Setting, And Participants: This multicenter cohort study used data from the Appendectomy Targeted Database of the American College of Surgeons Pediatric National Surgical Quality Improvement Program, which were augmented with operative report data obtained by supplemental medical record review.
Background: Our study evaluated general surgery resident indebtedness and perspectives on financial compensation.
Methods: In May 2020, a survey was distributed nationwide by general surgery program directors in the Association of Program Directors in Surgery on a voluntary basis to their residents.
Results: The survey was completed by 419 general surgery residents.
Introduction: The American Association of Pediatrics released guidelines in 2019 recommending delay of surgical referral in children with asymptomatic umbilical hernias until 4-5 y of age. The purpose of this study was to assess contemporary rates of potentially avoidable referrals in this cohort of children, and to assess whether rates have decreased following guideline release.
Methods: Retrospective analysis of umbilical hernias referrals evaluated at a single pediatric surgery clinic from October 2014 to August 2021.

Given the importance of operative documentation, we reviewed operative notes for surgeries that required splenic flexure mobilization (SFM) to determine their accuracy. We performed a retrospective review of 51 operative notes for complete SFMs performed at a single institution from January 2015 to June 2020. None of the operative notes reported a rationale for performing SFM, use of preoperative imaging to guide technical approach, reasoning for the operative method and mobilization approach used, or specific steps taken to ensure that SFM was done safely.

We conducted a historical review of the literature on the origin of the face mask, the scientific evidence of its benefits, and its implications for domestic and international politics. We performed a comprehensive search for peer- and nonpeer- reviewed literature published between 1905 and 2020.

Methods: We performed a retrospective chart review of 135 patients undergoing port placement for palliative chemotherapy at a single institution from January 2015 - July 2020.
Results: The median age was 68 (range 47-91).
Background: New surgeons are faced with inadequate mentoring when first entering practice. Our study examined challenges faced by young surgeons during their transition in practice and their mentoring experience when entering practice.
Methods: An article-based survey was mailed in August 2019 to general, colorectal, vascular, and cardiothoracic surgeons that became members of the American College of Surgeons within the past 5 years.
