Age and Weight Stratified Outcomes of Single Stage Endorectal Pull-through Procedures for Hirschsprung's Disease in Children: Analysis of NSQIP-P Data.

Background: We aimed to analyze the effect of age and weight on 30-day outcomes of single-stage endorectal pull tthrough (ERPT) procedures for Hirschsprung's Disease (HD) using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database to identify an optimal time for surgery.

Methods: We queried NSQIP-P for children <2 years with HD who underwent ERPT between 2016-2021 and did not have a preoperative stoma. Patients were stratified by age (<3 months, 3-6 months and >6 months) and weight (<4 kg, 4-8 kg, and >8 kg) at the time of surgery.

Impact of Perioperative Blood Transfusion on Postoperative Outcomes in Neonates.

Introduction: Neonatal postoperative outcomes may be negatively affected by perioperative red blood cell transfusion (RBCT). This study compared 30-day postoperative outcomes between transfused and non-transfused neonates.

Methods: The National Surgical Quality Improvement Program (NSQIP) Pediatric dataset (2021-2022) was used to analyze the association between RBCT and 30-day morbidity and mortality after neonatal surgery.

Major role of dolutegravir in the emergence of the S147G integrase resistance mutation.

Background: The S147G mutation is associated with high-level resistance to the integrase strand transfer inhibitor (INSTI) elvitegravir. In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

Uncommon Magnetic Ordering in the Quantum Magnet Yb_{3}Ga_{5}O_{12}.

The antiferromagnetic structure of Yb_{3}Ga_{5}O_{12} is identified by neutron diffraction experiments below the previously known transition at T_{λ}=54  mK. The magnetic propagation vector is found to be k=(1/2,1/2,0), an unusual wave vector in the garnet structure. The associated complex magnetic structure highlights the role of exchange interactions in a nearly isotropic system dominated by dipolar interactions and finds echoes with exotic structures theoretically proposed.

Antibiotic Prophylaxis for Elective Pediatric Laparoscopic Cholecystectomies.

Background: The Surgical Infection Society (SIS) guidelines recommend against the use of surgical antibiotic prophylaxis (SAP) for low-risk patients undergoing elective laparoscopic cholecystectomies.

Methods: Using National Surgical Quality Improvement Program (NSQIP) data, 5440 pediatric patients were identified who underwent laparoscopic cholecystectomy from 2021 to 2022. Patients who had immunodeficiency, active malignancy, American Society of Anesthesiologists (ASA) physical status classification 3-5, procedure indicated for infection, emergent procedure, received intravenous antibiotics before the prophylaxis window, or missing SAP data were excluded.
