IMPORTANCESmoking is a known risk to wound healing, but whether electronic cigarettes present the same risk remains unknown.OBJECTIVE To evaluate the rate of flap necrosis in the e-cigarette vapor-exposed group and the unexposed control and to detect a difference in the rate of flap necrosis between the traditional cigarette smoke-exposed group and the unexposed control.

Objective/Hypothesis: Studies have suggested preterm birth, defined as gestational age (GA) <37 weeks, is a risk factor for obstructive sleep apnea (OSA) in later childhood. However, little is known about the characteristics, severity, and degree of intervention of childhood OSA in former preterm infants compared to term infants. This study compares polysomnographic characteristics and surgical interventions in former preterm and term infants presenting with sleep disordered breathing.Study Design: Retrospective cohort study from 2015 to 2019 at a single tertiary referral center. Methods: Electronic Medical Records of pediatric patients ages 0 to 18 presenting with sleep disordered breathing were reviewed for gestational age, polysomnographic findings, clinical characteristics, and OSA surgical interventions. Association between gestational age, polysomnographic characteristics, and surgical interventions for OSA were reported.Results: A total of 615 patient records were analyzed. Adjusting for covariates, prematurity was associated with a 2.97× higher likelihood of development of severe OSA (aOR (95%CI): 2.97 (1.40-6.32)), increased apneic-hypoxic index (AHI) (mean (SD): 6.5 (9.8) vs. 4.6 (6.4), P < .05), increased end tidal CO 2 (50.5 (5.11) vs. 48.5 (5.8), P < .05), decreased REM latency (116 (64.7) vs. 132.4 (69.9), P < .05), and increased number of surgeries for OSA (0.65 (.95) vs. 0.45 (0.69), P < .05) compared to children born at term. Children born with GA < 32 weeks presented at a significantly later age with sleep disordered breathing (7.04 (.80) vs. 5.1 (0.15), P < .05) than children born at term.Conclusions: Prematurity was associated with increased likelihood of severe OSA, increased AHI, as well as increased number of surgical interventions for OSA compared to children born at term. These results suggest an association with preterm birth and increased severity of childhood OSA.

Objective To understand why pediatric otolaryngology patients do not attend scheduled clinic appointments and identify factors correlated with no‐show status. Study Design Retrospective cohort study. Methods This is a retrospective cohort study that uses medical record data extraction of patients that was scheduled to attend new patient appointments at a pediatric otolaryngology clinic in 2018. Results Factors associated with no‐shows included complex psychiatric history (OR (95% CI) 0.789 (0.71–0.88), P < .001), increased appointment lead time (OR (95% CI) 0.981 (0.976–0.987), P < .001), afternoon appointments (OR (95% CI) 0.783 (0.64–0.99), P = .038), and complex maternal medical history (OR (95% CI) 0.987 (0.979–0.996), P < .005). In contrast, factors associated with attendance included complex patients’ medical history (OR (95% CI) 1.058 (0.98–1.02), P < .001), primary care physician at the same hospital (OR (95% CI) 2.766 (2.25–3.39), P < .001), and primary language being Spanish (OR (95% CI) 2.536 (1.75–3.67) P < .001). The factors of distance from the hospital (OR (95% CI) 1.001 (0.99–1.01), P = .868), season of appointment (P = .997), race (P = .623), and ethnicity (P = .804) were not associated with attendance or no‐shows. Conclusion Patient and maternal medical problems, mental health history, primary care location, appointment lead time, hour of appointment, and primary language, all contribute to appointment attendance, while appointment timing, race, and ethnicity are not associated with attendance. Further work must be performed to overcome these barriers to minimize healthcare risks and improve patient outcomes. Quality of Evidence Level 3 Laryngoscope, 132:895–900, 2022

The properties of native spider silk vary within and across species due to the presence of different genes containing conserved repetitive core domains encoding a variety of silk proteins. Previous studies seeking to understand the function and material properties of these domains focused primarily on the analysis of dragline silk proteins, MaSp1 and MaSp2. Our work seeks to broaden the mechanical properties of silk-based biomaterials by establishing two libraries containing genes from the repetitive core region of the native Latrodectus hesperus silk genome (Library A: genes masp1, masp2, tusp1, acsp1; Library B: genes acsp1, pysp1, misp1, flag). The expressed and purified proteins were analyzed through Fourier Transform Infrared Spectrometry (FTIR). Some of these new proteins revealed a higher portion of β-sheet content in recombinant proteins produced from gene constructs containing a combination of masp1/masp2 and acsp1/tusp1 genes than recombinant proteins which consisted solely of dragline silk genes (Library A). A higher portion of β-turn and random coil content was identified in recombinant proteins from pysp1 and flag genes (Library B). Mechanical characterization of selected proteins purified from Library A and Library B formed into films was assessed by Atomic Force Microscopy (AFM) and suggested Library A recombinant proteins had higher elastic moduli when compared to Library B recombinant proteins. Both libraries had higher elastic moduli when compared to native spider silk proteins. The preliminary approach demonstrated here suggests that repetitive core regions of the aforementioned genes can be used as building blocks for new silk-based biomaterials with varying mechanical properties.
