Background: Current requirements for ethical research in Canada, specifically the standard of active or signed parental consent, can leave Indigenous children and youth with inequitable access to research opportunities or health screening. Our objective was to examine the literature to identify culturally safe research consent processes that respect the rights of Indigenous children, the rights and responsibilities of parents or caregivers, and community protocols., Methods: We followed PRISMA guidelines and Arksey and O'Malley's approach for charting and synthesizing evidence. We searched MEDLINE, PsycINFO, ERIC, CINAHL, Google Scholar, Web of Science, Informit Indigenous Collection, Bibliography of Native North Americans, and Sociological Abstracts. We included peer-reviewed primary and theoretical research articles written in English from January 1, 2000, to March 31, 2022, examining Indigenous approaches for obtaining informed consent from parents, families, children, or youth. Eligible records were uploaded to Covidence for title and abstract screening. We appraised the findings using a Two-Eyed Seeing approach. These findings were inductively coded using NVivo 12 and analyzed thematically., Results: We identified 2,984 records and 11 eligible studies were included after screening. Three key recommendations emerged: addressing tensions in the ethics of consent, embracing wise practices, and using relational approaches to consent. Tensions in consent concerned Research Ethics Board consent requirements that fall short of protecting Indigenous children and communities when culturally incongruent. Wise practices included allowing parents and children to consent together, land-based consenting, and involving communities in decision-making. Using relational approaches to consent embodied community engagement and relationship building while acknowledging consent for Indigenous children cannot be obtained in isolation from family and community., Conclusions: Very few studies discussed obtaining child consent in Indigenous communities. While Indigenous communities are not a monolith, the literature identified a need for community-driven, decolonized consent processes prioritizing Indigenous values and protocols. Further research is needed to examine nuances of Indigenized consent processes and determine how to operationalize them, enabling culturally appropriate, equitable access to research and services for all Indigenous children., (© 2024.

The literature on professional socialization focuses on how students adopt and internalize professional identities and values, and assumes that boundary work is essential to learning how best to practice their profession. However, a focus on boundary work in the context of midwifery training - which is embedded in the gendered and hierarchical landscape of maternity care - is lacking. Thus, this article examines how Canadian student-midwives learn to navigate and negotiate interprofessional boundaries. Grounded in a symbolic interactionist approach, it draws on 31 semi-structured qualitative interviews from a mixed-methods national study on midwifery retention, explores how midwifery students make sense of the tensions among midwives, physicians, and nurses, and describes what strategies they utilize when navigating boundaries. Our analysis, based in constructivist grounded theory, revealed that participants learned about interprofessional tensions in clinical placement encounters via direct or indirect interactions with other healthcare professionals, and that strategies to navigate these tensions included educating others about midwifery training and adopting a learner identity. This article proposes that the process of professional socialization enables to reshape professional boundaries and that students are not only learners but also agents of change. These findings may yield practical applications in health education by highlighting opportunities for improving interprofessional collaborations., (Copyright © 2024 Elsevier Ltd.

Introduction: Villitis of unknown etiology (VUE) is a histopathological lesion associated with adverse neonatal outcomes. We seek to define the obscure relationship between the severity and distribution of VUE and adverse neonatal outcomes., Methods: A retrospective chart review was conducted of pathologic findings from singleton placentas diagnosed with VUE between 2013 and 2019. Control placentas were matched 1:1 for gestational age and presence/absence of fetal IUGR. Neonatal outcomes of interest included: newborn resuscitation, NICU admission, Apgar scores and cord blood acidosis. Odds ratio and 95 % confidence intervals were calculated with controls as the reference., Results: 452 placentas were included. 35 % of pregnancies were complicated by IUGR. When analyzed by severity (low-grade: OR = 4.75 [2.86-8.14]; high-grade: OR = 4.76 [2.71-8.79]) and distribution (focal: OR = 5.24 [2.87-10.17]; multifocal: OR = 4.90 [2.90-8.59]), VUE was significantly associated with need for newborn resuscitation. No other neonatal outcomes of interest were significantly associated with VUE diagnosis., Discussion: We determined a statistically significant association between VUE severity and distribution and the need for newborn resuscitation. VUE lesions were not associated with any additional neonatal outcomes of interest. Further studies with larger sample sizes are required to confirm these associations for obstetric and neonatal case management., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2023 Elsevier Ltd.

Placental histopathology provides insights, or "snapshots", into relevant antenatal factors that could elevate the risk of perinatal brain injury. We present a systematic review and meta-analysis comparing frequencies of adverse neurological outcomes in infants born to women with placental abruption versus without abruption. Records were sourced from MEDLINE, Embase, and the CENTRAL Trials Registry from 1946 to December 2019. Studies followed the PRISMA guidelines and compared frequencies of neurodevelopmental morbidities in infants born to pregnant women with placental abruption (exposure) versus women without placental abruption (comparator). The primary endpoint was cerebral palsy. Periventricular and intraventricular (both severe and any grades of IVH) and any histopathological neuronal damage were the secondary endpoints. Study methodologic quality was assessed by the Ottawa-Newcastle scale. Estimated odds ratios (OR) and hazards ratio (HR) were derived according to study design. Data were meta-analyzed using a random effects model expressed as pooled effect sizes and 95% confidence intervals. We included eight observational studies in the review, including 1245 infants born to women with placental abruption. Results of the random effects meta-analysis show that the odds of infants born to pregnant women with placental abruption who experience cerebral palsy is higher than in infants born to pregnant women without placental abruption (OR 5.71 95% CI (1.17, 27.91); I 2 = 84.0%). There is no statistical difference in the odds of infants born to pregnant women with placental abruption who experience severe IVH (grade 3+) (OR 1.20 95% CI (0.46, 3.11); I 2 = 35.8%) and any grade of IVH (OR 1.20 95% CI (0.62, 2.32); I 2 = 32.3%) vs. women without placental abruption. There is no statistically significant difference in the odds of infants born to pregnant women with placental abruption who experience PVL vs. pregnant women without placental abruption (OR 6.51 95% CI (0.94, 45.16); I 2 = 0.0%). Despite our meta-analysis suggesting increased odds of cerebral palsy in infants born to pregnant women with placental abruption versus without abruption, this finding should be interpreted cautiously, given high heterogeneity and overall poor quality of the included studies.

We examined neonatal outcomes in pregnancies complicated by placental abruption (PA) and acute chorioamnionitis (CA). Exposure was acute CA; primary outcome - fetal death; secondary outcomes - adverse Apgar score, neonatal intensive care unit (NICU) admission, and cardiac depression. 267 placentas - 18.4% exhibited acute CA. PA pregnancies with CA - 29% experienced fetal death. Funisitis, acute CA and adverse neonatal outcomes are dependent. Without accounting for funisitis, aforementioned findings hold, though effect sizes are smaller. PA, acute CA with funisitis could affect fetal death and NICU admission. Acute CA and PA alone could impact fetal death and adverse Apgar scores., Competing Interests: Declaration of interest None., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

Background: No systematic review and meta-analysis to date has examined multiple child and parent-reported social and physical quality of life (QoL) in pediatric populations affected by Hirschsprung's disease (HD) and anorectal malformations (ARM). The objective of this systematic review is to quantitatively summarize the parent-reported and child-reported psychosocial and physical functioning scores of such children., Methods: Records were sourced from the CENTRAL, EMBASE, and MEDLINE databases. Studies that reported child and parent reported QoL in children with HD and ARM, regardless of surgery intervention, versus children without HD and ARM, were included. The primary outcome was the psychosocial functioning scores, and the secondary outcomes were the presence of postoperative constipation, postoperative obstruction symptoms, fecal incontinence, and enterocolitis. A random effects meta-analysis was used., Results: Twenty-three studies were included in the systematic review, with 11 studies included in the meta-analysis. Totally, 1678 total pediatric patients with HD and ARM underwent surgery vs 392 healthy controls. Pooled parent-reported standardized mean (SM) scores showed better social functioning after surgery (SM 91.79, 95% CI (80.3 to 103.3), I 2 =0). The pooled standardized mean difference (SMD) showed evidence for parent-reported incontinence but not for constipation in children with HD and ARM after surgery that had a lower mean QoL score compared with the normal population (SMD -1.24 (-1.79 to -0.69), I 2 =76% and SMD -0.45, 95% CI (-1.12 to 0.21), I 2 =75%). The pooled prevalence of child-reported constipation was 22% (95% CI (16% to 28%), I 2 =0%). The pooled prevalence of parent-reported postoperative obstruction symptoms was 61% (95% CI (41% to 81%), I 2 =41%)., Conclusion: The results demonstrate better social functioning after surgery, lower QoL scores for incontinence versus controls, and remaining constipation and postoperative obstruction symptoms after surgery in children with HD and ARM., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objective: One option for the treatment of perforated appendicitis in pediatric patients is interval appendectomy (IA). A patient decision aid (PDA) can be useful in the decision-making process regarding IA. The purpose of this study was to evaluate parents' decisional conflict before and after engaging with a developed PDA., Methods: Participants included (a) parents who are considering IA surgery for their child, (b) have not yet had their follow-up appointment postdischarge, and (c) were fluent in either the official languages of English or French. This study used a pretest and post-test design to measure participants' decisional conflict and treatment option choice. Perceptions and acceptability of the PDA were also assessed., Results: A total of 18 participants completed the study (16 mothers). Major findings include significant decreases in all Decisional Conflict Scale items from pre-PDA to post-PDA engagement, except for one item. The majority of participants perceived the PDA to be useful, easy to find information regarding risks and provided enough information to help them make a decision regarding their child's treatment., Conclusions: This is the first study to develop and evaluate a PDA among parents who are making a decision regarding IA surgery. The results showed a significant decrease in decisional conflict after using the PDA. The results also showed that the PDA was generally accepted among parents and had positive perceptions regarding length, content, and balance. The use of PDA for this population can help ease feelings of decisional conflict and equip parents with the information to make informed decisions., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Villitis of unknown etiology (VUE) is associated with fetal growth restriction (FGR) and adverse short-term neonatal outcomes. No investigation to date has found which VUE features are driving the association with FGR diagnosis., Methods: A retrospective cohort study of placenta pathology specimens (2013-2017) was conducted. Independent variables of interest were: VUE distribution (focal vs diffuse), location (basal vs non-basal), and grade (high vs low). The primary outcome was FGR, and secondary outcomes were neonatal intensive care unit (NICU) admission, NICU length of stay, Apgar scores <7 at 1, 5, and 10-min, and recurrence rate of villitis in subsequent pregnancies. Association between VUE characteristics and our primary outcome were investigated using logistic regression. Secondary outcomes were explored with regression analyses and recurrence rate of VUE for members of the cohort with a recorded subsequent pregnancy was calculated., Results: One hundred and twenty seven placentas were included. Adjusted models showed no difference in the odds of FGR between high-grade versus low-grade VUE [aOR 1.25 95% CI (0.50, 3.26), p = 0.6], focal/multi-focal vs diffuse cases [aOR 1.03 95% CI (0.28, 4.34), p = >0.9], and basal vs non-basal VUE [aOR 0.06 95% CI (0.00, 1.10), p = 0.058]. After adjusting for prematurity <37 weeks, there were lower odds of NICU admission in basal vs non-basal cases [aOR 0.25, 95% CI (0.06, 0.90), p = 0.048). There was no difference in the odds of neonates presenting with Apgar <7 for the distinct VUE histopathology features. Three cases had recurrent VUE, resulting in a 6.8% [95% CI (3.02%, 10.61%)] recurrence rate. All recurrent cases were high-grade and identified with basal localization., Discussion: There are no statistical associations between distinct VUE features and FGR diagnosis, however location of villitis may be associated with worse neonatal outcomes. Villitis of any type (severity, degree, location) could potentially drive insufficient placental function and poor fetal growth., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Elsevier Ltd.

No systematic review to date has examined histopathological parameters in relation to native liver survival in children who undergo the Kasai operation for biliary atresia (BA). A systematic review and meta-analysis is presented, comparing the frequency of native liver survival in peri-operative severe vs. non-severe liver fibrosis cases, in addition to other reported histopathology parameters. Records were sourced from MEDLINE, Embase, and CENTRAL databases. Studies followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and compared native liver survival frequencies in pediatric patients with evidence of severe vs. non-severe liver fibrosis, bile duct proliferation, cholestasis, lobular inflammation, portal inflammation, and giant cell transformation on peri-operative biopsies. The primary outcome was the frequency of native liver survival. A random effects meta-analysis was used. Twenty-eight observational studies were included, 1,171 pediatric patients with BA of whom 631 survived with their native liver. Lower odds of native liver survival in the severe liver fibrosis vs. non-severe liver fibrosis groups were reported (odds ratio [OR], 0.16; 95% confidence interval [CI], 0.08-0.33; I 2 =46%). No difference in the odds of native liver survival in the severe bile duct destruction vs. non-severe bile duct destruction groups were reported (OR, 0.17; 95% CI, 0.00-63.63; I 2 =96%). Lower odds of native liver survival were documented in the severe cholestasis vs. non-severe cholestasis (OR, 0.10; 95% CI, 0.01-0.73; I 2 =80%) and severe lobular inflammation vs. non-severe lobular inflammation groups (OR, 0.02; 95% CI, 0.00-0.62; I 2 =69%). There was no difference in the odds of native liver survival in the severe portal inflammation vs. non-severe portal inflammation groups (OR, 0.03; 95% CI, 0.00-3.22; I 2 =86%) or between the severe giant cell transformation vs. non-severe giant cell transformation groups (OR, 0.15; 95% CI, 0.00-175.21; I 2 =94%). The meta-analysis loosely suggests that the presence of severe liver fibrosis, cholestasis, and lobular inflammation are associated with lower odds of native liver survival in pediatric patients after Kasai., Competing Interests: Conflict of Interest: The authors have no financial conflicts of interest., (Copyright © 2022 by The Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition.)

Aim: To examine (1) what role preceptors play in students' learning; (2) how student-preceptor relationships can impact students' views of the profession and their decision to leave the program; and (3) what strategies can be used to improve the preceptor-student relationship to facilitate student retention., Research Design and Participants: We used a qualitative methodological approach utilising semi-structure interviews with 31 midwifery students across Canada. Participants were recruited from all midwifery education programs and were in various stages of their educational journey. The interviews were conducted in English and French. Inductive analysis followed Charmaz's guidelines moving from line-by-line to focused coding and development of analytical categories., Findings: The results show that positive relationships with preceptors boosted students' confidence and contributed to the constructive learning experiences among trainees. Students pointed out that their best learning experiences were facilitated by preceptors who created a safe space to make mistakes and were knowledgeable and invested in students' learning. Students also suggested that power imbalance is embedded in student-preceptor relationships and can negatively impact students' learning experiences and their decision to stay in the program., Key Conclusions and Implications for Practice: It is important to consider how to mitigate the power imbalance embedded in preceptor-student relationship. Offering more training to preceptors, oversight of preceptors' mentorship skills by midwifery educators, and creation of ombudsperson's position might mitigate some of the power differential and facilitate students' ability to complete midwifery training., Competing Interests: Declaration of Competing Interest The authors have no conflict of interest., (Copyright © 2022.

Objective: To establish reference intervals (RIs) for fetal and neonatal small and large intestinal lengths., Methods: Linear measurements on small and large intestines were made upon postmortem examination of 131 preterm and term infants with gestational ages between 13 and 41 weeks. All cases were referred from the Eastern Ontario and Western Québec regions to a tertiary care hospital. Age and sex partitions were considered and RI limits were estimated., Results: Data consisted of 72 male (54.96%) and 59 female (45.04%) fetuses and neonates with mean gestational age of 25.6 weeks. Results showed that small and large intestinal lengths increased linearly with gestational age. RIs for small intestinal length (cm) of fetuses and neonates aged 13-20 weeks were (21.1, 122.4); of those aged 21-28 weeks were (57.7, 203.8); of those aged 29-36 weeks were (83.6, 337.1); and of those aged 37-41 weeks were (132.8, 406.4). RIs for large intestinal length (cm) of fetuses and neonates from the same four age groups were (5.1, 21.4), (12.7, 39.7), (32.4, 62.4), and (29.1, 82.2)., Conclusions: Establishing accurate RIs for premature and term infants has clinical relevance for pathologists performing postmortem analysis and for surgeons planning postoperative management of patients. The results of this study reaffirm that fetal small and large intestinal lengths increase linearly with gestational age irrespective of sex. Future studies should aim to further investigate the role of possible confounders on growth of fetal intestinal length, including maternal factors such as age and substance use during pregnancy., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Collins et al developed a histology scoring system (EoE HSS) to assess multiple pathologic features. The aim of this study is to identify if the EoE HSS can better detect endoscopic and symptom improvement vs the Peak Eosinophilic Count (PEC)., Methods: A retrospective chart review was performed for patients during 2014-2016. All patients ≤18 years old with a diagnosis of EoE and whose records included initial and follow-up upper gastrointestinal endoscopies were included. Severity and extent of endoscopic features were scored using 8 parameters, from normal to maximum change for each location of the esophageal biopsy., Results: Forty patients with EoE were included in the study, of which 35 (87.5%) patients demonstrated symptom and 25 (62.5%) endoscopic improvement at the time of follow-up. In the proximal esophagus, the EoE HSS outperformed the change in eosinophil count of the Children's Hospital of Eastern Ontario (CHEO) practice in predicting endoscopic improvement by 16.8% when examining the change in grade and 17.1% when examining the change in stage scores., Conclusions: At our institution, adoption of the EoE HSS in assessing biopsies of EoE patients might be warranted, compared to the traditional practice. However, a bigger sample size may give a more robust difference in all locations.

Background: The efficacy of performing a restorative proctocolectomy and J-pouch ileoanal anastomosis without diverting ileostomy in children with inflammatory bowel disease has been a longstanding debate. A systematic review and meta-analysis is presented comparing the occurrence of postoperative complications in children who underwent either the pouch-anal anastomosis (IPAA) with ileostomy (diverted) versus the undiverted procedure., Methods: Records were sourced from CINAHL, CENTRAL, EMBASE and MEDLINE databases. Studies followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and compared postoperative complications in pediatric patients diagnosed with inflammatory diseases aged less than 18 years who underwent J-pouch with ileostomy versus without ileostomy. The primary outcome was the occurrence of postoperative leaks, and the secondary outcomes were presence of postoperative small bowel obstruction (SBO), pouchitis, stricture and fistula complications. A random-effects meta-analysis was used., Results: Twenty-three observational studies in the systematic review were included with 658 patients (83% diverted, 17% undiverted). Pooled estimates showed no difference in occurrence of leaks in children who underwent J-pouch/IPAA with ileostomy versus without (odds ratio (OR) 0.54, 95% confidence interval (CI) 0.17 to 1.64, I 2 =16%). There was no difference in the occurrence of SBO, pouchitis or strictures in children who underwent J-pouch/IPAA with ileostomy versus without (SBO: OR 2.27, 95% CI 0.52 to 9.92, I 2 =0%, pouchitis: OR 1.76, 95% CI 0.95 to 3.24, I 2 =0%, strictures: OR 2.72, 95% CI 0.44 to 16.69, I 2 =66%)., Conclusion: The meta-analysis did not find differences in the occurrence of complications in pediatric patients who underwent the IPAA with ileostomy procedure versus without ileostomy., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objectives: Appendicitis is one of the most commonly encountered pediatric surgical diagnoses, with non-operative management of perforated appendicitis leading to two treatment options: an interval appendectomy (IA) or expectant management. The primary objective of this study was to assess parents' need for a patient decision aid (PDA) among parents considering IA or expectant management. A secondary objective was to determine parent preferences for the format and distribution plan of a drafted patient decision aid., Methods: Coulter's systematic development process for PDA was used to guide the assessment interviews for parents. Participants included caregivers of a patient who experienced perforated appendicitis, and admission between 2019 and 2020. Semi-structured individual interviews were conducted to collect information about decision-making needs of parents of children who experienced perforated appendicitis., Results: A total of 12 different parents participated in the interviews. Results indicate decisional conflict associated with the lack of evidence for optimal treatment, supporting the need for the development of a patient decision aid to assist in clarifying information and parent values with practitioners. Parents clearly identified a need for evidence to support decision-making in various formats (eg, pamphlet or electronic). Timing of when to deliver the PDA varied (ie, during hospital admission, at discharge, or at follow-up appointment)., Conclusion: Results indicated various factors contributing to parental decisional conflict, including the lack of evidence showing the optimal treatment, the need for more information, and guidance from practitioners. Overall, findings indicate a strong need for a patient decision aid., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Pediatric surgical practice lags behind medicine in presence and use of evidence, primarily due to time constraints of using existing tools that are not specific to pediatric surgery, lack of sufficient patient data and unstructured pediatric surgery training methods., Method: We developed, disseminated and tested the effectiveness of an evidence-based resource for pediatric surgeons and researchers that provides brief, informative summaries of quality-assessed systematic reviews and meta-analyses on conflicting pediatric surgery topics., Results: Responses of 91 actively practicing surgeons who used the resource were analysed. The majority of participants found the resource useful (75%), improved their patient care (66.6%), and more than half (54.2%) found it useful in identifying research gaps. Almost all participants reported that the resource could be used as a teaching tool (93%)., Conclusion: Lack of awareness of the resource is the primary barrier to its routine use, leading to potential calls for more active dissemination worldwide. Users of the Canadian Association of Paediatric Surgeons Evidence-Based Resource find that the summaries are useful, identify research gaps, help mitigate multiple barriers to evidence-based medicine, and may improve patient care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.
