Abstract
BACKGROUND The posterior sagittal anorectoplasty (PSARP) used to repair an anorectal malformation (ARM) with a rectovestibular fistula involves incising the perineal body skin and the sphincter muscles and a posterior sagittal incision to the coccyx. Perineal body dehiscence is the most common and morbid complication post-PSARP which can have a negative impact on future bowel control. With consideration of all the other approaches described to repair this anomaly, we developed a perineal body sparing modification of the standard PSARP technique. METHODS Four patients with ARM with a rectovestibular fistula were repaired with a perineal body sparing modified PSARP at a single institution between 2020 and 2021. The incision used was limited, involving only the length of the anal sphincter, with no incision anterior or posterior to the planned anoplasty. Dissection of the distal rectum and fistula was performed without cutting the perineal body. Once the distal rectum was mobilized off the posterior vaginal wall and out of the vestibule, the perineal body muscles, where the fistula had been, were reinforced and an anoplasty was then performed. RESULTS Operative time was the same as for a standard PSARP. There were no intraoperative or postoperative complications. No postoperative dilations were performed. All patients healed well with an excellent cosmetic result. All are too young to assess for bowel control. CONCLUSION We present a new technique, a modification of the traditional PSARP for rectovestibular fistula, which spares the perineal body. This approach could eliminate the potential complication of perineal body dehiscence.

Abstract
Materials employed in the treatment of conditions encountered in surgical and clinical practice frequently face barriers in translation to application. Shortcomings can be generalized through their reduced mechanical stability, difficulty in handling, and inability to conform or adhere to complex tissue surfaces. To overcome an amalgam of challenges, research has sought the utilization of polymer-derived nanomaterials deposited in various fashions and formulations to improve the application and outcomes of surgical and clinical interventions. Clinically prevalent applications include topical wound dressings, tissue adhesives, surgical sealants, hemostats, and adhesion barriers, all of which have displayed the potential to act as superior alternatives to current materials used in surgical procedures. In this review, emphasis will be placed not only on applications, but also on various design strategies employed in fabrication. This review is designed to provide a broad and thought-provoking understanding of nanomaterials as adjuvant tools for the assisted treatment of pathologies prevalent in surgery. This article is categorized under: Implantable Materials and Surgical Technologies > Nanomaterials and Implants Implantable Materials and Surgical Technologies > Nanoscale Tools and Techniques in Surgery.

Abstract
OBJECTIVES Postoperative bile leakage is a common complication of hepatobiliary surgery and frequently requires procedural intervention. Bile-label 760 (BL-760), a novel near-infrared dye, has emerged as a promising tool for identifying biliary structures and leakage, owing to its rapid excretion and strong bile specificity. This study aimed to assess the intraoperative detection of biliary leakage using intravenously administered BL-760 compared with intravenous (IV) and intraductal (ID) indocyanine green (ICG). MATERIALS AND METHODS Laparotomy and segmental hepatectomy with vascular control were performed on two 25-30 kg pigs. ID ICG, IV ICG, and IV BL-760 were administered separately, followed by an examination of the liver parenchyma, cut liver edge, and extrahepatic bile ducts for areas of leakage. The duration of intra- and extrahepatic fluorescence detection was assessed, and the target-to-background (TBR) of the bile ducts to the liver parenchyma was quantitatively measured. RESULTS In Animal 1, after intraoperative BL-760 injection, three areas of leaking bile were identified within 5 min on the cut liver edge with a TBR of 2.5-3.8 that was not apparent to the naked eye. In contrast, after IV ICG administration, the background parenchymal signal and bleeding obscured the areas of bile leakage. A second dose of BL-760 demonstrated the utility of repeated injections, confirming two of the three previously visualized areas of bile leakage and revealing one previously unseen leak. In Animal 2, neither ID ICG nor IV BL-760 injections showed obvious areas of bile leakage. However, fluorescence signals were observed within the superficial intrahepatic bile ducts after both injections. CONCLUSIONS BL-760 enables the rapid intraoperative visualization of small biliary structures and leaks, with the benefits of fast excretion, repeatable intravenous administration, and high-fluorescence TBR in the liver parenchyma. Potential applications include the identification of bile flow in the portal plate, biliary leak or duct injury, and postoperative monitoring of drain output. A thorough assessment of the intraoperative biliary anatomy could limit the need for postoperative drain placement, a possible contributor to severe complications and postoperative bile leak.

Abstract
Immunotherapy is a key modality in the treatment of cancer, but many tumors remain immune resistant. The classic mouse model of B16-F10 melanoma is immune resistant even in the face of checkpoint inhibition. Apolipoprotein E (apoE), a known immune suppressant is strikingly elevated in many human tumors, but its role in cancer immunology is not defined. We investigated the role of apoE in the immune micro-environment using a mouse melanoma model. We demonstrate that ApoE is -highly expressed in wild-type B16-F10 melanoma and serum levels progressively increase as tumors grow. The conditioned media from wild type ApoE secreting melanoma cells suppress T-cell activation in vitro while this suppressive effect is absent in conditioned media from ApoE knock out tumor cells. Mechanistically, apoE induces IL-10 secreting dendritic cells and stimulates T-cell apoptosis and arrest partially via the lrp8 receptor. Ablating ApoE in mice inoculated with tumor cells enabled tumor cell rejection and was associated with induction of immune pathway activation and immune cell infiltration. Tumor secreted apoE appears to be a potent immune cell checkpoint and targeting apoE is associated with enhanced tumor immunity in the mouse melanoma model.

Abstract
INTRODUCTION Laparoscopic Nissen fundoplication with gastrostomy tube (LPNF-GT) placement is often indicated in children with congenital cardiac diseases (CCDs) for nutritional optimization. This study aims to evaluate institutional outcomes of LPNF-GT, with a team-based approach in operative management. METHODS Five years of an institutional database at a tertiary care children's hospital was queried for LPNF-GT in children with CCDs. Descriptive analyses were performed. A national comparison was performed utilizing the 2012-2013 Pediatrics NSQIP database, using propensity score matching. Outcome measures of interest were operative-time, unplanned readmission, and 30-day mortality. RESULTS A team-based approach was utilized in 51 cases. Median operative time was 68.5 (IQR: 48-89) minutes. All patients tolerated tube feeds postoperatively. All patients survived 30 days post surgery. When compared to 136 similarly matched children nationally, the risk-adjusted operative time with a team-based approach was 47.38 (12.43-82.33) minutes shorter (P < .05). There were no statistically significant differences in the likelihood of being in the hospital past 30 days, unplanned readmissions, and mortality (P > .05). CONCLUSION LPNF-GT can be safely performed in children with CCDs. A team-based approach demonstrates improved operative time and achieved similar outcomes when compared nationally.

Abstract
Abstract
Purpose: Pediatric high grade gliomas (HGG), high risk medulloblastomas (MB) and neuroblastomas (NB) are malignant neurological tumors with poor prognosis despite major advancements in current therapeutic interventions. The standard of care therapy for such high risk tumors includes surgical resection, when possible, and radio-therapy with or without chemo-therapy. Therapeutic failure may be due to radio- and/or chemo-resistance and the maintenance of an aggressive stem-like sub-population of cells within the bulk tumors. Epigenetic deregulation is implicated in pediatric neurological cancer malignancies where the bromo- and extra-terminal domain (BET) protein activity may play a role in histone H3K27 acetylation leading to tumorigenesis and radio-resistance.
Methods and Results: We used the BET inhibitor JQ-1 to determine the radio-sensitizing effect on a panel of human pediatric neurological cancer cell lines including: NB (IMR-32 and SKNSH), MB (D556 and D283) and HGG (GBM01 and DIPG07). Cells were seeded 24 hours (h) before treatment with 1 µM dose of JQ-1 for an additional 24 h before irradiation (IR) with 6Gy (JL Shepherd Mark 1 137Cs Irradiator). IncuCyte (Essen Biosciences, Ann Arbor, MI) live cell imaging recorded cellular proliferation (confluency) over 6 days post IR, revealing that while single treatment with JQ-1 or 6Gy irradiation alone significantly reduced cell proliferation in all the tested cell lines, the combination of JQ-1 pre-treatment followed by 6Gy IR differentially impaired proliferation capacity in all cell lines except DIPG07 by further reducing cell proliferation. To determine the mechanism of radio-sensitization induced by JQ-1, Western blot and Immunofluorescence analysis revealed increased p-γH2AX foci at 24 h post IR in JQ-1 pre-treated cells. Furthermore, the stem cell maintenance and tumorigenic proteins OCT-4, MYCN, HSP90, L1-CAM, RAB5C and FABP5 were differentially expressed after JQ-1 treatment. Next we assessed the effect of JQ-1 on cellular migration and stem-cell maintenance using the ‘wound-healing' scratch and tumor-sphere self-renewal assays, respectively. Cell migration was significantly (P < 0.05) inhibited with JQ-1 in both human NB (IMR-32 and SKNSH) and MB (D556 and D283) cell lines. Tumor-sphere formation efficiency was significantly (P < 0.05) reduced in IMR-32, SKNSH, D556, D283 and DIPG cells after treatment with JQ-1. Morphological cellular differentiation, evidenced by long neurite extensions, was induced after JQ-1 treatment in the D556, IMR-32 and SKNSH cells.
Conclusions: Our data show potent anti-stem cell activity as well as decreased proliferation, migration and enhanced radiosensitivity following JQ-1 treatment. These effects may be due to delayed DNA repair mechanisms, differential expression of stem cell maintenance and tumorigenic proteins and induced differentiation of the malignant cancer stem cells.

Abstract
INTRODUCTION The pediatric quality indicator (PDI) measures released by the Agency for Healthcare Research and Quality (AHRQ) provide an impetus for benchmarking quality of care in children. The PDI-17, aimed at studying perforation in appendicitis, is one such measure that this study aims to utilize to assess surgical care delivery and outcomes in children managed at majority-minority hospitals. METHODS The Kid Inpatient Database (2000-2012) was queried for pediatric patients (< 18 years) with a diagnosis of appendicitis, with and without perforation. Facilities were categorized into tertiles based on rates of perforation (PDI-17). Similarly, tertiles were generated based on volume of minority patients (Black and Hispanic) treated at each facility. Multivariable regression analysis adjusted for demographic parameters, hospital-level characteristics, propensity score quintiles, clinically relevant outcomes, and tertiles of minority patients treated. RESULTS Of the 322,805 patients with appendicitis 28.7% had perforated appendicitis. Patients presenting to facilities caring for a higher volume of perforated appendicitis were younger with public insurance or no insurance and, however, these patients were less likely to belong to a minority group (p < 0.05). Additionally, these patients were less likely to belong to the highest income quartile (OR [95% CI] 0.45 [0.39-0.52]). Hospitals treating the highest volume of minority patients [majority-minority hospitals (MMHs)] had an 87% (OR [95% CI] 1.87 [1.77-1.98]) increased likelihood of also treating the highest rates of perforated appendicitis. CONCLUSION Hospitals treating a high volume of complicated appendicitis are less likely to care for minority groups. Additionally, MMHs lacking experience and volume in caring for complicated appendicitis have an increased likelihood of patients with perforations which is indicative of poor healthcare access.

Abstract
INTRODUCTION Acute rehabilitation following traumatic injuries is associated with improved functional recovery. Access is often limited to patients at the time of hospital discharge. This phenomenon remains less well described in children, who may have more to benefit with rehabilitation posttrauma. This study aims to determine factors influencing access to rehabilitation among children with traumatic injuries utilizing a nationally representative sample. METHODS The Kids Inpatient Database (2000-2012) was queried for trauma patients. The outcome measure of interest was discharge with rehabilitative services [acute rehabilitation facilities or home healthcare (HHC)]. Patients that did not survive and those that did not meet hospital admission criteria were excluded. Multivariable models adjusted for age, race/ethnicity, gender, insurance-status, income, injury severity score, year, children's hospital designation, hospital-volume, teaching status, location, and geographical region. RESULTS A total of 811,941 records were included. These were predominantly male (65.9%) with an average age of 11.6 (±6.7) years. 4.2% were discharged to rehabilitation facilities, and 3.9% were discharged with HHC. African-American and Hispanic patients were less likely to be placed/have access to rehabilitation facilities (p < 0.001). Similarly, uninsured patients were less likely to receive these services postdischarge (p < 0.05). However, patients with government insurance, those in the highest income-quartile, those treated at children's hospitals, and those treated at teaching and urban hospitals were more likely to be placed/have access to rehabilitation services. CONCLUSION Race/ethnicity and insurance status are associated with disparities in access to postdischarge rehabilitation in pediatric trauma patients. Moreover, treatment at designated children's, teaching and urban hospitals better-facilitates discharge planning with rehabilitative services.

Abstract
Childhood neuroblastoma is one of the most common types of extra-cranial cancer affecting children with a clinical spectrum ranging from spontaneous regression to malignant and fatal progression. In order to improve the clinical outcomes of children with high-risk neuroblastoma, it is crucial to understand the tumorigenic mechanisms that govern its malignant behaviors. MYCN proto-oncogene, bHLH transcription factor (MYCN) amplification has been implicated in the malignant, treatment-evasive nature of aggressive, high-risk neuroblastoma. In this study, we used a SILAC approach to compare the proteomic signatures of MYCN-amplified IMR-32 and non-MYCN-amplified SK-N-SH human neuroblastoma cells. Tumorigenic proteins, including fatty-acid binding protein 5 (FABP5), L1-cell adhesion molecule (L1-CAM), baculoviral IAP repeat containing 5 [BIRC5 (survivin)] and high mobility group protein A1 (HMGA1) were found to be significantly upregulated in the IMR-32 compared to the SK-N-SH cells and mapped to highly tumorigenic pathways including, MYC, MYCN, microtubule associated protein Tau (MAPT), E2F transcription factor 1 (E2F1), sterol regulatory element binding transcription factor 1 or 2 (SREBF1/2), hypoxia-inducible factor 1α (HIF-1α), Sp1 transcription factor (SP1) and amyloid precursor protein (APP). The transcriptional knockdown (KD) of MYCN, HMGA1, FABP5 and L1-CAM significantly abrogated the proliferation of the IMR-32 cells at 48 h post transfection. The early apoptotic rates were significantly higher in the IMR-32 cells in which FABP5 and MYCN were knocked down, whereas cellular migration was significantly abrogated with FABP5 and HMGA1 KD compared to the controls. Of note, L1-CAM, HMGA1 and FABP5 KD concomitantly downregulated MYCN protein expression and MYCN KD concomitantly downregulated L1-CAM, HMGA1 and FABP5 protein expression, while survivin protein expression was significantly downregulated by MYCN, HMGA1 and FABP5 KD. In addition, combined L1-CAM and FABP5 KD led to the concomitant downregulation of HMGA1 protein expression. On the whole, our data indicate that this inter-play between MYCN and the highly tumorigenic proteins which are upregulated in the malignant IMR-32 cells may be fueling their aggressive behavior, thereby signifying the importance of combination, multi-modality targeted therapy to eradicate this deadly childhood cancer.
