Abstract
BACKGROUND Individuals with esophageal atresia (EA) have lifelong increased risk for mucosal and structural pathology of the esophagus. The use of surveillance endoscopy to detect clinically meaningful pathology has been underexplored in pediatric EA. We hypothesized that surveillance endoscopy in pediatric EA has high clinical yield, even in the absence of symptoms. STUDY DESIGN The medical records of all patients with EA who underwent at least 1 surveillance endoscopy between March 2004 and March 2023 at an international EA referral center were retrospectively reviewed. The primary outcomes were endoscopic identification of pathology leading to an escalation in medical, endoscopic, or surgical management. Logistic regression analysis examined predictors of actionable findings. Nelson-Aalen analysis estimated optimal endoscopic surveillance intervals. RESULTS Five hundred forty-six children with EA underwent 1,473 surveillance endoscopies spanning 3,687 person-years of follow-up time. A total of 770 endoscopies (52.2%) in 394 unique patients (72.2%) had actionable pathology. Esophagitis leading to escalation of therapy was the most frequently encountered finding (484 endoscopies, 32.9%), with most esophagitis attributed to acid reflux. Barrett's esophagus (intestinal metaplasia) was identified in 7 unique patients (1.3%) at a median age of 11.3 years. No dysplastic lesions were identified. Actionable findings leading to surgical intervention were found in 55 children (30 refractory reflux and 25 tracheoesophageal fistulas). Significant predictors of actionable pathology included increasing age, long gap atresia, and hiatal hernia. Symptoms were not predictive of actionable findings, except dysphagia, which was associated with stricture. Nelson-Aalen analysis predicted occurrence of an actionable finding every 5 years. CONCLUSIONS Surveillance endoscopy uncovers high rates of actionable pathology even in asymptomatic children with EA. Based on the findings of the current study, a pediatric EA surveillance endoscopy algorithm is proposed.

Abstract
PURPOSE Vocal fold movement impairment (VFMI) secondary to recurrent laryngeal nerve (RLN) injury is a common source of morbidity after pediatric cervical, thoracic, and cardiac procedures. Flexible laryngoscopy (FL) is the gold standard to diagnose VFMI yet can be challenging to perform and/or risks possible clinical decompensation in some children and is an aerosolizing procedure. Laryngeal ultrasound (LUS) is a potential non-invasive alternative, but limited data exists in the pediatric surgical population regarding its efficacy. We aimed to investigate the diagnostic accuracy of LUS compared to FL in evaluating VFMI. METHODS A prospective, single-center, single-blinded (rater) cohort study was undertaken on perioperative pediatric patients at risk for RLN injury. Patients underwent FL and LUS. Cohen's kappa was used to determine chance-corrected agreement. RESULTS Between 2021 and 2023, 85 paired evaluations were performed with patients having a median (IQR) age of 10 (4, 42) months and weight of 7.5 (5.4, 13.4) kilograms. The prevalence of VFMI was 27.1%. Absolute agreement between evaluations was 98.8% (kappa 0.97, 95% CI: 0.91-1.00, P < 0.001). The sensitivity and specificity of LUS in detecting VFMI was 95.7% and 100%, yielding a positive predictive value (PPV) of 100% and negative predictive value (NPV) of 98.4% (95% CI: 90-100%). Diagnostic accuracy was 98.8% (95% CI: 93-100%). CONCLUSION LUS is a highly accurate modality in evaluating VFMI in children. While FL remains the gold standard for diagnosis, LUS offers a low-risk screening modality for children at risk for VFMI such that only those with an abnormal LUS or presence of clinical symptoms discordant with LUS findings should undergo FL. TYPE OF STUDY Prospective, single-center, single blinded (rater), cohort study. LEVEL OF EVIDENCE Level II.

Abstract
Abstract
The COVID-19 pandemic created an unprecedented shortage of personal protective equipment (PPE) for healthcare workers - especially respirators. In response to a lack of commercial respirator equipment, a multidisciplinary prototyping hackathon was held and the key components required to develop an inexpensive, scalable "COVID-19 Reusable Elastomeric Respirator" (RER-19) were identified. Available hospital supplies were assessed based on their published technical specifications to meet each of the key component requirements. The fully assembled prototype was then validated through user testing, and volunteers underwent standard fit testing with cardiopulmonary monitoring while wearing the RER-19 in a small pilot study. Multiple social media platforms were then used to disseminate educational information on respirator assembly, use, and maintenance. Here we present our institution's initial experience with prototyping to meet a specific healthcare challenge, in combination with prompt dissemination of information to educate and empower healthcare workers in the face of a critical PPE shortage during an unprecedented and evolving pandemic.

Abstract
Our purpose was to investigate polymeric gels for use as a highly transparent radiotherapy bolus and determine the relevant physical and dosimetric properties. We first quantified tensile properties (maximum stress, strain, and Young modulus) for various polymeric gels, along with a commercial bolus product in order to illustrate the wide variety of potential materials. For a select polymeric gel with tensile properties similar to currently used radiotherapy bolus, we also evaluated mass and electron density, effective atomic number, optical transparency, and percent depth dose in clinical megavoltage photon and electron beams. For this polymeric gel, mass density was 872 ± 12 and 896 ± 13 g/cm3 when measured via weight/volume and computed tomography Hounsfield units, respectively. Electron density was 2.95 ± 0.04 ×1023 electrons/cm3. Adding fused silica (9% by weight) increases density to that of water. The ratio of the effective atomic number to that of water without and with added silica was 0.780 and 0.835 at 1 MeV, 0.767 and 0.826 at 6 MeV, and 0.746 and 0.809 at 20 MeV. Percent depth dose for 6 MV photons was within 2% of water within the first 2.5 cm and after scaling by the density coincided within 1% out to >7 cm. For 6 and 20 MeV electrons, after scaling for density D80% was within 1.3 and 1.5 mm of water, respectively. The high transparency and mechanical flexibility of polymeric gels indicate potential for use as a radiotherapy bolus; differences in density from water may be managed via either using “water equivalent thickness” or by incorporating fused silica into the material.
