Metabolite extraction is the critical first-step in metabolomics experiments, where it is generally regarded to inactivate and remove proteins. Here, arising from efforts to improve extraction conditions for polar metabolomics, we discover a proteomic landscape of over 1000 proteins within metabolite extracts. This is a ubiquitous feature across several common extraction and sample types. By combining post-resuspension stable isotope addition and enzyme inhibitors, we demonstrate in-extract metabolite interconversions due to residual transaminase activity. We extend these findings with untargeted metabolomics where we observe extensive protein-mediated metabolite changes, including in-extract formation of glutamate dipeptide and depletion of total glutathione. Finally, we present a simple extraction workflow that integrates 3 kDa filtration for protein removal as a superior method for polar metabolomics. In this work, we uncover a previously unrecognized, protein-mediated source of observer effects in metabolomics experiments with broad-reaching implications across all research fields using metabolomics and molecular metabolism., (© 2024.

Per- and polyfluoroalkyl substances (PFAS) in the environment pose persistent and complex threats to human and wildlife health. Around the world, PFAS point sources such as military bases expose thousands of populations of wildlife and game species, with potentially far-reaching implications for population and ecosystem health. But few studies shed light on the extent to which PFAS permeate food webs, particularly ecologically and taxonomically diverse communities of primary and secondary consumers. Here we conducted >2000 assays to measure tissue-concentrations of 17 PFAS in 23 species of mammals and migratory birds at Holloman Air Force Base (AFB), New Mexico, USA, where wastewater catchment lakes form biodiverse oases. PFAS concentrations were among the highest reported in animal tissues, and high levels have persisted for at least three decades. Twenty of 23 species sampled at Holloman AFB were heavily contaminated, representing middle trophic levels and wetland to desert microhabitats, implicating pathways for PFAS uptake: ingestion of surface water, sediments, and soil; foraging on aquatic invertebrates and plants; and preying upon birds or mammals. The hazardous long carbon-chain form, perfluorooctanosulfonic acid (PFOS), was most abundant, with liver concentrations averaging >10,000 ng/g wet weight (ww) in birds and mammals, respectively, and reaching as high 97,000 ng/g ww in a 1994 specimen. Perfluorohexanesulfonic acid (PFHxS) averaged thousands of ng/g ww in the livers of aquatic birds and littoral-zone house mice, but one order of magnitude lower in the livers of upland desert rodent species. Piscivores and upland desert songbirds were relatively uncontaminated. At control sites, PFAS levels were strikingly lower on average and different in composition. In sum, legacy PFAS at this desert oasis have permeated local aquatic and terrestrial food webs across decades, severely contaminating populations of resident and migrant animals, and exposing people via game meat consumption and outdoor recreation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Racial disparities in lung cancer screening (LCS) are well established. Black Veterans are among those at the highest risk for developing lung cancer but are less likely to complete LCS. We sought to identify barriers and facilitators to LCS uptake among Black Veterans., Patients and Methods: A qualitative study using semistructured interviews was conducted with 32 Black Veterans to assess for barriers, facilitators, and contextual factors for LCS and strategies to improve screening. Veterans were purposively sampled by age, sex, and LCS participation status (ie, patients who received a low-dose CT [LDCT], patients who contacted the screening program but did not receive an LDCT, and patients who did not connect with the screening program nor receive an LDCT). Interview guides were developed using the Theoretical Domains Framework and Health Belief Model. Data were analyzed using rapid qualitative analysis., Results: Barriers of LCS uptake among Black Veterans include self-reported low LCS knowledge and poor memory, attention, and decision processes associated with the centralized LCS process. Facilitators of LCS uptake among Black Veterans include social/professional role; identity and social influences; perceived susceptibility, threat, and consequences due to smoking status and military or occupational exposures; emotion, behavioral regulation, and intentions; and high trust in providers. Environmental context and resources (eg, transportation) and race and racism serve as contextual factors that did not emerge as having a major impact on LCS uptake. Strategies to improve LCS uptake included increased social messaging surrounding LCS, various forms of information dissemination, LCS reminders, balanced and repeated shared decision-making discussions, and streamlined referrals., Conclusions: We identified addressable barriers and facilitators for LCS uptake among Black Veterans that can help focus efforts to improve disparities in screening. Future studies should explore provider perspectives and test interventions to improve equity in LCS.

This article describes an interprofessional collaboration between Sanford Health and North Dakota State University that strengthens agricultural injury surveillance in the upper Midwest by using multiple sources of health data and geographic information systems (GIS) technology. We provide methodological insights and considerations for using and combining facility-level trauma registry (FLTR) data, national data sets, and GIS to identify areas with disproportionate agricultural injury prevalence. Additionally, we discuss the benefits of FLTR data, how and why it is collected, the data it contains, and how it can be combined with national datasets to fill-in surveillance gaps. Lastly, we offer recommendations for building cross-institutional and interprofessional partnerships.

Objectives: The purpose of the present study was to characterize the incidence, injury characteristics, and outcomes of patients presented to four trauma facilities located in the upper Midwest with tractor-related agricultural injuries., Methods: We performed a retrospective review of the facility level trauma registries of four trauma centers located in North Dakota, South Dakota, and Minnesota between January 1, 2010 and December 31, 2021. We characterized the incidence, severity and outcomes of traumatic tractor-related agricultural injuries for pediatric and adult patients. We described the nature of these injuries by severity, anatomical site, type, age, sex, and length of stay (LoS). Injury severity was evaluated using Injury Severity Score (ISS) and Abbreviated Injury Scale (AIS)., Results: Findings indicated that farmers aged 65 and older experience polytraumatic, severe tractor-related agricultural injuries and fatalities. Of the 177 tractor patients analyzed, 40 patients were between the ages of 65 and 74 years and 45 patients were 75 and over. Male farmers aged 65 and older are injured year-round, many are discharged to skilled nursing facilities for additional care, are spending more time in the hospital, and have the highest rate of critical injuries out of all age groups. Moreover, the patients who died as a result of tractor-related agricultural injuries were men over 65 years. The most common tractor-related agricultural injuries include falls from tractors ( n  = 53), struck by object falling/propelled from tractor ( n  = 25), rollovers ( n  = 26), and runovers ( n  = 24). Falls from tractors accounted for 33% of all tractor-related upper extremity fractures, 36% of head injuries and 29% of chest injuries., Conclusion: The findings from this study indicate that tractor-related agricultural injuries represent a significant problem in the upper Midwest. Older, male farm workers experience a higher incidence of tractor-related agricultural injuries, and all tractor-related fatalities occurred in individuals 65 years of age and older. These results underscore the need for further investigation into aging-related farm safety issues.

Objective: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance., Design: Cross-sectional survey-based evaluation., Setting: International comprehensive cleft care workshop., Participants: Total of 489 participants., Interventions: Three-day simulation-based hybrid comprehensive cleft care workshop., Main Outcome Measures: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance., Results: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P  = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P  = .01)., Conclusion: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

Objectives: The purpose of the present study was to characterize the incidence, injury characteristics, and outcomes of patients presented to a Level I adult trauma center in Fargo, North Dakota, with farm machinery injuries (FMI)., Methods: We performed a retrospective review of the trauma registry of Sanford Medical Center Fargo (SMCF) between January 2010 and December 2020. We compared admission characteristics of FMI admissions to non-FMI admissions, identified the types of machinery that are most commonly associated with FMI, and described the nature of these injuries by severity, anatomical site, type, age, sex, and length of stay (LoS). Injury severity was evaluated using Injury Severity Score (ISS)., Results: Findings indicated that FMI admissions had a higher mean ISS, longer ICU LoS, and a higher mortality rate than non-FMI admissions. The leading cause of fatal and non-fatal FMI in this region are tractors. Males experience 91.2% of tractor injuries, and individuals 65 and over account for nearly 53% of all tractor injuries (n = 18). Males accounted for all deaths, tractor and otherwise. The "other machinery" category was the second most common category and accounted for 50% of female patients. Additionally, 24.5% of all FMI are related to machine maintenance., Conclusion: The findings from this study indicate that FMI injuries represent a significant problem in the upper Midwest. Older, male farm workers experience a higher incidence of tractor-related injuries, and all tractor-related deaths occurred in individuals 65 years of age and older. These results underscore the need for further investigation into aging-related farm safety issues.

Background: A haplotype is a set of DNA variants inherited together from one parent or chromosome. Haplotype information is useful for studying genetic variation and disease association. Haplotype assembly (HA) is a process of obtaining haplotypes using DNA sequencing data. Currently, there are many HA methods with their own strengths and weaknesses. This study focused on comparing six HA methods or algorithms: HapCUT2, MixSIH, PEATH, WhatsHap, SDhaP, and MAtCHap using two NA12878 datasets named hg19 and hg38. The 6 HA algorithms were run on chromosome 10 of these two datasets, each with 3 filtering levels based on sequencing depth (DP1, DP15, and DP30). Their outputs were then compared., Result: Run time (CPU time) was compared to assess the efficiency of 6 HA methods. HapCUT2 was the fastest HA for 6 datasets, with run time consistently under 2 min. In addition, WhatsHap was relatively fast, and its run time was 21 min or less for all 6 datasets. The other 4 HA algorithms' run time varied across different datasets and coverage levels. To assess their accuracy, pairwise comparisons were conducted for each pair of the six packages by generating their disagreement rates for both haplotype blocks and Single Nucleotide Variants (SNVs). The authors also compared them using switch distance (error), i.e., the number of positions where two chromosomes of a certain phase must be switched to match with the known haplotype. HapCUT2, PEATH, MixSIH, and MAtCHap generated output files with similar numbers of blocks and SNVs, and they had relatively similar performance. WhatsHap generated a much larger number of SNVs in the hg19 DP1 output, which caused it to have high disagreement percentages with other methods. However, for the hg38 data, WhatsHap had similar performance as the other 4 algorithms, except SDhaP. The comparison analysis showed that SDhaP had a much larger disagreement rate when it was compared with the other algorithms in all 6 datasets., Conclusion: The comparative analysis is important because each algorithm is different. The findings of this study provide a deeper understanding of the performance of currently available HA algorithms and useful input for other users., (© 2023. The Author(s).)

Breast cancer is well recognized as a leading type of cancer affecting women in the United States. Although breast cancer screening is well supported in the literature, there is a lack of clear agreement regarding which breast cancer risk calculating tools should be used to develop personalized screening regimens. In this review of 11 primary articles published from 2017 through 2022, we assess current evidence on breast cancer risk assessment in outpatient clinic and mammography settings and the pivotal role of health care providers in influencing patients' choices regarding individualized screenings. Risk assessment is strongly recommended by multiple clinical practice guidelines, yet there is inadequate evidence to endorse one risk assessment tool as best practice. Further research is needed to integrate risk assessment within the clinic workflow and screening encounters. Patient-centered communication and shared decision-making are critical components for managing each woman's perceived risk and objective risk for breast cancer., (Copyright © 2023 AWHONN.

Introduction: Farm children and youths face unique health risks, including increased risk of agricultural injuries (AI), due to the hazardous machinery, structures and animals on their residential environment. As a result, they experience more severe and complex polytraumatic injuries and longer hospital stays compared to those children injured in homes or residences. A major barrier to the prevention of AI among children and youth residing on farms is a lack of analytic studies about the magnitude and characteristics of these injuries, especially in North Dakota., Methods: We performed a retrospective review of the Sanford Medical Center Fargo trauma registry for pediatric patients (aged 0-19 years) who received care between January 2010 and December 2020 for AI. Patients were grouped for analysis by the age categories of the Agricultural Youth Work Guidelines (AYWG) to compare the mechanisms of injury with the recommended minimum age requirements for specific farm tasks., Results: Of the 41 patients, 26 were male. Mean age was 11 years and one death was reported. The most common mechanism of injury was animals (37%), followed by falls (20%) and machinery (17%). Children under 6 years and youth aged 16 to 19 had the highest number of injuries. Females experienced 53% of animal-related injuries and males accounted for all vehicle-related injuries., Conclusion: The incidence and severity of polytraumatic AI among young children in North Dakota is concerning. Our results underscore the continued need to pursue pediatric injury prevention on farms through educational resources and programs, including the AWYG., Practical Applications: Parents require more training on age and ability appropriate farm tasks, especially animal-related interactions. It is imperative that families are given the education and training necessary to integrate children into the farm life while protecting them from injury., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

22q11.2 deletion syndrome, associated with congenital and neuropsychiatric anomalies, is the most common copy number variant (CNV)-associated syndrome. Patient-derived, induced pluripotent stem cell (iPS) models have provided insight into this condition. However, patient-derived iPS cells may harbor underlying genetic heterogeneity that can confound analysis. Furthermore, almost all available models reflect the commonly-found ~ 3 Mb "A-D" deletion at this locus. The ~ 1.5 Mb "A-B" deletion, a variant of the 22q11.2 deletion which may lead to different syndromic features, and is much more frequently inherited than the A-D deletion, remains under-studied due to lack of relevant models. Here we leveraged a CRISPR-based strategy to engineer isogenic iPS models of the 22q11.2 "A-B" deletion. Differentiation to excitatory neurons with subsequent characterization by transcriptomics and cell surface proteomics identified deletion-associated alterations in proliferation and adhesion. To illustrate in vivo applications of this model, we further implanted neuronal progenitor cells into the cortex of neonatal mice and found potential alterations in neuronal maturation. The isogenic models generated here will provide a unique resource to study this less-common variant of the 22q11.2 microdeletion syndrome., (© 2023. The Author(s).)

AbstractThe extent to which species ranges reflect intrinsic physiological tolerances is a major question in evolutionary ecology. To date, consensus has been hindered by the limited tractability of experimental approaches across most of the tree of life. Here, we apply a macrophysiological approach to understand how hematological traits related to oxygen transport shape elevational ranges in a tropical biodiversity hot spot. Along Andean elevational gradients, we measured traits that affect blood oxygen-carrying capacity-total and cellular hemoglobin concentration and hematocrit, the volume percentage of red blood cells-for 2,355 individuals of 136 bird species. We used these data to evaluate the influence of hematological traits on elevational ranges. First, we asked whether the sensitivity of hematological traits to changes in elevation is predictive of elevational range breadth. Second, we asked whether variance in hematological traits changed as a function of distance to the nearest elevational range limit. We found that birds showing greater hematological sensitivity had broader elevational ranges, consistent with the idea that a greater acclimatization capacity facilitates elevational range expansion. We further found reduced variation in hematological traits in birds sampled near their elevational range limits and at high absolute elevations, patterns consistent with intensified natural selection, reduced effective population size, or compensatory changes in other cardiorespiratory traits. Our findings suggest that constraints on hematological sensitivity and local genetic adaptation to oxygen availability promote the evolution of the narrow elevational ranges that underpin tropical montane biodiversity.

Although victim blaming in the context of sexual assault is often emphasized, little research has compared rates of victim blaming following sexual assault relative to other forms of victimization. This research investigated whether there is a crime-specific bias toward blaming victims of sexual assault. Victim blaming was assessed via different methods from the observer perspective in vignette-based studies, as well as survivors' accounts of social reactions they received. In Study 1, participants were asked to rate how much the survivor was to blame in three vignettes, each with a different randomized crime outcome: rape, physical assault, or theft. Study 2 assessed blame for a vignette that either ended in rape or theft, via a causal attribution statement. Study 3 asked interpersonal trauma survivors who had experienced at least two forms of victimization (i.e., sexual assault, physical assault, or theft) to report the social reactions they received following disclosure of each of these crimes. Across all three studies, victim blaming occurred following multiple forms of victimization and there was no evidence of a particular bias toward blaming survivors of sexual assault more so than other crimes. However, results of Study 3 highlight that, following sexual assault, survivors receive more silencing and stigmatizing reactions than they experienced after other crimes. Interpersonal traumas (i.e., sexual or physical assault) also resulted in more egocentric responses compared to theft. Altogether, there does not appear to be a crime-specific bias for victim blaming; however, crime-specific bias is apparent for some other, potentially understudied, social reactions. Implications of these findings highlight the value of victim blaming education and prevention efforts through trauma-informed services and outreach following victimization. Furthermore, service providers and advocates might especially seek to recognize and prevent silencing and stigmatizing reactions following sexual assault disclosures.

Objective: Improve the quality and diversity of candidates invited for the Otolaryngology-Head and Neck Surgery residency match by reducing geographical and inter-rater bias with a novel geographic distribution algorithm., Methods: Interview applicants were divided into geographic regions and assigned to reviewers. Each reviewer selected by force-ranking a pre-determined number of applicants to invite for interviews based on the percentage of applications received for each region. Our novel geographic distribution algorithm was then applied to maintain the geographic representation and underrepresented minority status of invited applicants to match the applicant pool., Results: Analysis of previous interview selection methods demonstrated a statistically significant overrepresentation of local applicants invited for interviews. In 2022, 324 domestic applications were received for the otolaryngology match, which were divided into six geographic regions. There was no significant difference in USMLE scores between regions. The implementation of our distribution algorithm during applicant selection eliminated local overrepresentation in the invited pool of applicants and maintained the representation of underrepresented minority applicants. Following the match, reviewers indicated that implementation of the geographic distribution algorithm was simple and improved the quality and diversity of the group of interviewed applicants., Conclusion: Traditional methods of scoring and inviting otolaryngology residency applicants can be confounded by regional and inter-rater biases. Employing a geographic distribution algorithm improves the quality and diversity of invited applicants, eliminates bias, and maintains the representation of underrepresented minority applicants., Competing Interests: All authors confirm that they have no conflict of interest in the submission of this manuscript., (© 2022 The Authors.

Background: The GILLS (gastroesophageal reflux, preoperative intubation, late intervention (>14 days), low birth weight (<2500 g), and syndromic diagnosis) score is a validated predictor of success for tongue-lip adhesion (TLA) in patients with Robin sequence (RS). Objective: To evaluate the application of the GILLS score to mandibular distraction osteogenesis (MDO) for airway management in patients with RS and the associated syndromes. Methods: A retrospective chart review of 21 patients diagnosed with RS and treated with MDO surgery between the years 2006 and 2016 was performed. Success was defined by tracheostomy status outcome measures. Statistical analysis of the success was completed. Results: A GILLS score limit of ≤3 had a positive predictive value of 100%, a negative predictive value of 50%, 83% sensitivity, and 100% specificity. Conclusions: These data imply that the GILLS scoring algorithm is applicable to aiding in the selection of patients with RS for MDO, including patients with known syndromes.

Background: Little is known about the effects of secondhand marijuana smoke on children. We aimed to determine caregiver marijuana use prevalence and evaluate any association between secondhand marijuana smoke, childhood emergency department (ED) or urgent care (UC) visitation, and several tobacco-related illnesses: otitis media, viral respiratory infections (VRIs), and asthma exacerbations., Methods: This study was a cross-sectional, convenience sample survey of 1500 subjects presenting to a pediatric ED. The inclusion criteria were as follows: caregivers aged 21-85 years, English- or Spanish-speaking. The exclusion criteria were as follows: children who were critically ill, medically complex, over 11 years old, or using medical marijuana., Results: Of 1500 caregivers, 158 (10.5%) reported smoking marijuana and 294 (19.6%) reported smoking tobacco. Using negative-binomial regression, we estimated rates of reported ED/UC visits and specific illnesses among children with marijuana exposure and those with tobacco exposure, compared to unexposed children. Caregivers who used marijuana reported an increased rate of VRIs in their children (1.31 episodes/year) compared to caregivers with no marijuana use (1.04 episodes/year) (p = 0.02)., Conclusions: Our cohort did not report any difference with ED/UC visits, otitis media episodes, or asthma exacerbations, regardless of smoke exposure. However, caregivers of children with secondhand marijuana smoke exposure reported increased VRIs compared to children with no smoke exposure., Impact: Approximately 10% of caregivers in our study were regular users of marijuana. Prior studies have shown that secondhand tobacco smoke exposure is associated with negative health outcomes in children, including increased ED utilization and respiratory illnesses. Prior studies have shown primary marijuana use is linked to negative health outcomes in adults and adolescents, including increased ED utilization and respiratory illnesses. Our study reveals an association between secondhand marijuana smoke exposure and increased VRIs in children. Our study did not find an association between secondhand marijuana smoke exposure and increased ED or UC visitation in children., (© 2021.

The multifaceted long-term impairments resulting from critical illness and COVID-19 require interdisciplinary management approaches in the recovery phase of illness. Operational insights into the structure and process of recovery clinics (RCs) from heterogeneous health systems are needed. This study describes the structure and process characteristics of existing and newly implemented ICU-RCs and COVID-RCs in a subset of large health systems in the United States., Design: Cross-sectional survey., Setting: Thirty-nine RCs, representing a combined 156 hospitals within 29 health systems participated., Patients: None., Interventions: None., Measurement and Main Results: RC demographics, referral criteria, and operating characteristics were collected, including measures used to assess physical, psychologic, and cognitive recoveries. Thirty-nine RC surveys were completed (94% response rate). ICU-RC teams included physicians, pharmacists, social workers, physical therapists, and advanced practice providers. Funding sources for ICU-RCs included clinical billing ( n = 20, 77%), volunteer staff support ( n = 15, 58%), institutional staff/space support ( n = 13, 46%), and grant or foundation funding ( n = 3, 12%). Forty-six percent of RCs report patient visit durations of 1 hour or longer. ICU-RC teams reported use of validated scales to assess psychologic recovery (93%), physical recovery (89%), and cognitive recovery (86%) more often in standard visits compared with COVID-RC teams (psychologic, 54%; physical, 69%; and cognitive, 46%)., Conclusions: Operating structures of RCs vary, though almost all describe modest capacity and reliance on volunteerism and discretionary institutional support. ICU- and COVID-RCs in the United States employ varied funding sources and endorse different assessment measures during visits to guide care coordination. Common features include integration of ICU clinicians, interdisciplinary approach, and focus on severe critical illness. The heterogeneity in RC structures and processes contributes to future research on the optimal structure and process to achieve the best postintensive care syndrome and postacute sequelae of COVID outcomes., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2022 The Authors.

Objective: Velopharyngeal insufficiency (VPI) is a common speech disorder in patients with a history of cleft palate (CP) or 22q11.2 deletion syndrome. Pharyngeal flap (PF) and sphincter pharyngoplasty (SP) are 2 common surgeries to treat this disorder by decreasing unwanted nasal air emission and hypernasal resonance. Because Eustachian tube dysfunction (ETD) in patients with CP may be more frequent after surgery for VPI, we examined whether ETD was associated with either type of surgery., Design: Retrospective cohort study., Setting: Children's hospital-based tertiary referral center., Patients: A total of 225 children with VPI who underwent primary PF (201) or SP (24) between 2006 and 2017., Outcome Measures: We examined differences in risk of ETD according to both surgical groups and proxies for postoperative nasal obstruction. These proxies included postoperative resonance measures and development of obstructive sleep apnea (OSA)., Results: Both surgical groups had similar preoperative measures, except the PF group had higher hypernasality by PSA. Postoperatively, the PF group demonstrated lower hypernasal resonance by nasometry and PSA. There were no differences between PF and SP groups with regard to ETD. Proxies for postoperative nasal obstruction also were not predictive of postoperative ETD. Degree of CP and younger age were found to be risk factors for ETD., Conclusion: There was no significant difference in the effects of PF and SP on ETD in this study. Neither lower hypernasality nor incidence of OSA had any impact on ETD. Degree of CP and younger age were the only significant risk factors for ETD that this study identified.
