Abstract

After overexposure to loud music, we experience a decrease in our ability to hear (robustness), which usually recovers (resilience). Here, we exploited the amenable auditory system of the desert locust, Schistocerca gregaria , to measure how robustness and resilience depend on age. We found that gene expression changes are dominated by age as opposed to noise exposure. We measured sound-evoked nerve activity for young and aged locusts directly, after 24 hours and 48 hours after noise exposure. We found that both young and aged locusts recovered their auditory nerve function over 48 hours. We also measured the sound-evoked transduction current in individual auditory neurons, and although the transduction current magnitude recovered in the young locusts after noise exposure, it failed to recover in the aged locusts. A plastic mechanism compensates for the decreased transduction current in aged locusts. We suggest key genes upregulated in young noise-exposed locusts that mediate robustness to noise exposure and find potential candidates responsible for compensatory mechanisms in the auditory neurons of aged noise-exposed locusts.

Abstract

Controversy persists regarding the ideal surgical approach for repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We examined complications and outcomes of infants undergoing thoracoscopy and thoracotomy for repair of Type C EA/TEF using propensity score-based overlap weights to minimize the effects of selection bias. Secondary analysis of two databases from multicenter retrospective and prospective studies examining outcomes of infants with proximal EA and distal TEF who underwent repair at 11 institutions was performed based on surgical approach. Regression analysis using propensity score-based overlap weights was utilized to evaluate outcomes of patients undergoing thoracotomy or thoracoscopy for Type C EA/TEF repair. Of 504 patients included, 448 (89%) underwent thoracotomy and 56 (11%) thoracoscopy. Patients undergoing thoracoscopy were more likely to be full term (37.9 vs. 36.3 weeks estimated gestational age, p < 0.001), have a higher weight at operative repair (2.9 vs. 2.6 kg, p < 0.001), and less likely to have congenital heart disease (16% vs. 39%, p < 0.001). Postoperative stricture rate did not differ by approach, 29 (52%) thoracoscopy and 198 (44%) thoracotomy (p = 0.42). Similarly, there was no significant difference in time from surgery to stricture formation (p > 0.26). Regression analysis using propensity score-based overlap weighting found no significant difference in the odds of vocal cord paresis or paralysis (OR 1.087 p = 0.885), odds of anastomotic leak (OR 1.683 p = 0.123), the hazard of time to anastomotic stricture (HR 1.204 p = 0.378), or the number of dilations (IRR 1.182 p = 0.519) between thoracoscopy and thoracotomy. Infants undergoing thoracoscopic repair of Type C EA/TEF are more commonly full term, with higher weight at repair, and without congenital heart disease as compared to infants repaired via thoracotomy. Utilizing propensity score-based overlap weighting to minimize the effects of selection bias, we found no significant difference in complications based on surgical approach. However, our study may be underpowered to detect such outcome differences owing to the small number of infants undergoing thoracoscopic repair. Level III. [ABSTRACT FROM AUTHOR]

47. Natural history and consequence of patent processus vaginalis: An interim analysis from a multi-institutional prospective observational study.

Abstract

The prevalence and natural history of patent processus vaginalis (PPV) are unknown. An interim analysis was performed of a multi-institutional, prospective, observational study in neonates undergoing laparoscopic pyloromyotomy during which bilateral inguinal canals were evaluated. Infants under 4 months undergoing laparoscopic pyloromyotomy were enrolled at 8 children's hospitals. The presence of a PPV was evaluated and measurements recorded. Patients with a PPV are undergoing annual phone follow-up to 18 years of age. Interim analysis was performed. In a cohort of 610 patient, 80 did not have a PPV examined, 4 had consent issues and were excluded, leaving 526 patients. Of these, 433 (82%) were male, median age 1.2 months (IQR 0.9, 1.6), median weight 3.89 kg (IQR 3.4, 4.46), and EGA 39 weeks (IQR 37, 40). There were 283 PPVs, 132 bilateral (47%), 116 right (41%), and 35 left (12%). Patients with a PPV were significantly younger (1.1 months (IQR 0.9, 1.5) vs 1.3 months (IQR 0.9, 1.7), p=0.02), weighed less (3.76kg (IQR 3.35, 4.26) vs 3.9kg (IQR 3.4, 4.5) p=0.03) and had a significantly lower EGA at birth (38 weeks (IQR 37, 40) vs 39 weeks (IQR 38, 40) p=0.003). Of 246 eligible infants, 208 (85%) responded to at least one annual follow-up. Two patients had an inguinal hernia repair for a symptomatic hernia, 49- and 51-days post pyloromyotomy. One had an orchiopexy and incidental inguinal hernia repair 120 days post pyloromyotomy; for a total of 3 (1.2%) hernia repairs. No additional hernias were identified in 116 patients with the PPV patients who have been followed for > 1 year. The presence of a PPV at the time of pyloromyotomy is common but the need for hernia repair is rare within the first year of life. Continued long-term longitudinal follow-up of this cohort is needed.

48. Evaluating the risk of peri-umbilical hernia after sutured or sutureless gastroschisis closure.

Abstract

• Peri-umbilical hernia after successful gastroschisis closure is a consequence rather than complication, regardless of method. • Repair may be reasonably delayed, and safely observed, similar to umbilical hernias in the pediatric population. • Like pediatric umbilical hernias, spontaneous closure occurs with minimal complications. We evaluate the incidence, outcomes, and management of peri‑umbilical hernias after sutured or sutureless gastroschisis closure. A retrospective, longitudinal follow-up of neonates with gastroschisis who underwent closure at 11 children's hospitals from 2013 to 2016 was performed. Patient encounters were reviewed through 2019 to identify the presence of a peri‑umbilical hernia, time to spontaneous closure or repair, and associated complications. Of 397 patients, 375 had follow-up data. Sutured closure was performed in 305 (81.3%). A total of 310 (82.7%) infants had uncomplicated gastroschisis. Peri-umbilical hernia incidence after gastroschisis closure was 22.7% overall within a median follow-up of 2.5 years [IQR 1.3,3.9], and higher in those with uncomplicated gastroschisis who underwent primary vs. silo assisted closure (53.0% vs. 17.2%, p < 0.001). At follow-up, 50.0% of sutureless closures had a persistent hernia, while 16.4% of sutured closures had a postoperative hernia of the fascial defect (50.0% vs. 16.4%, p < 0.001). Spontaneous closure was observed in 38.8% of patients within a median of 17 months [9,26] and most frequently observed in those who underwent a sutureless primary closure (52.2%). Twenty-seven patients (31.8%) underwent operative repair within a median of 13 months [7,23.5]. Rate and interval of spontaneous closure or repair were similar between the sutured and sutureless closure groups, with no difference between those who underwent primary vs. silo assisted closure. Peri-umbilical hernias after sutured or sutureless gastroschisis closure may be safely observed similar to congenital umbilical hernias as spontaneous closure occurs, with minimal complications and no additional risk with either closure approach.
