This diabesity epidemic is increasingly impacting children and adolescents, and there is scarce evidence of interventions with favourable long-term outcomes.Purpose: In order to understand the determinants of diabesity and how to address them, multiple stakeholders were invited to a meeting to discuss current state of knowledge and to help design a program to prevent pediatric and adolescent diabesity.Participants and methods: The meeting was held at McMaster University on March 4th, 2015. The event involved presentations to deliver state-of-the-art knowledge about diabesity, and roundtable discussions of several domains including nutrition, physical activity, sleep, and mental health. Discussion transcripts were analyzed using NVivo.Results: Forty-nine participants took part in the workshop. They included clinical healthcare professionals, public health, Aboriginal Patient Navigator, research scientists, students, and patients with family members. A total of 628 reference counts from the roundtable discussions were coded under 20 emerging themes. Participants believed that the most important elements of the program involve the provision of knowledge and education, family involvement, patient motivation, location of program delivery, and use of surveys and questionnaires for outcome measurement.Conclusion: Effective pediatric and adolescent diabesity prevention programs should be conceptualized by multidisciplinary stakeholders and embrace the complexity of diabesity with multiprong interventions. This meeting provided a framework for developing such interventions.Keywords: diabesity, meeting, pediatric, adolescent, obesity, pediatric type 2 diabetes mellitus

AIM: rett syndrome is a severe neurodevelopmental disorder that typically affects females. Little is known about the natural history and survival time of these females. METHOD: we compared the survival of all Austrian female participants from Rett's historical cohort (1966) with that of affected females registered in the Australian Rett Syndrome Database. The analysis included both Kaplan-Meier analysis and a log-rank test for equality of survivor functions. RESULTS: of females in the original Austrian group, three are still alive. The median age at death was 13 years 4.8 months. The probability of survival up to the age of 25 years was 21%, compared with 71% in the Australian cohort (p<0.001). We found no practical or statistically significant differences in survival between the various birth year groups within the Australian cohort. INTERPRETATION: our data indicate that survival of females with Rett syndrome has improved since the late 1960s but that there has been shown no change in survival over the last 30 years, possibly because the follow-up time has been too short.

At present, there is no internationally accepted set of core outcomes or measurement methods for epilepsy clinical practice. The International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group of experts in epilepsy, people with epilepsy, and their representatives to develop minimum sets of standardized outcomes and outcome measurement methods for clinical practice. Using modified Delphi consensus methods with consecutive rounds of online voting over 12 months, a core set of outcomes and corresponding measurement tool packages to capture the outcomes were identified for infants, children, and adolescents with epilepsy. Consensus methods identified 20 core outcomes. In addition to the outcomes identified for the ICHOM Epilepsy adult standard set, behavioral, motor, and cognitive/language development outcomes were voted as essential for all infants and children with epilepsy. The proposed set of outcomes and measurement methods will facilitate the implementation of the use of patient-centered outcomes in daily practice., (© 2024 The Authors.

At present, there is no internationally accepted set of core outcomes or measurement methods for epilepsy clinical practice. Therefore, the International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group of experts in epilepsy, people with epilepsy and their representatives to develop minimum sets of standardized outcomes and outcomes measurement methods for clinical practice that support patient-clinician decision-making and quality improvement. Consensus methods identified 20 core outcomes. Measurement tools were recommended based on their evidence of strong clinical measurement properties, feasibility, and cross-cultural applicability. The essential outcomes included many non-seizure outcomes: anxiety, depression, suicidality, memory and attention, sleep quality, functional status, and the social impact of epilepsy. The proposed set will facilitate the implementation of the use of patient-centered outcomes in daily practice, ensuring holistic care. They also encourage harmonization of outcome measurement, and if widely implemented should reduce the heterogeneity of outcome measurement, accelerate comparative research, and facilitate quality improvement efforts., (© 2024 The Authors.

The aim of this review is to revisit the meaning of common concepts and frameworks promoted to capture subjective outcomes of patients, the content of their corresponding measurements, and the preferred sources of the information of interest. This is important because conceptualizations of 'health' and the subject evaluations thereof continue to evolve. Related but distinct concepts like quality of life (QoL), health-related QoL (HRQoL), functional status, health status, and well-being are often used indiscriminately to assess clinical impacts of interventions and to influence decisions about patient care and policymaking. The discussion addresses and illustrates the following issues: (1) the required features of effective and valid health-related concepts; (2) understanding underlying factors that often create confusion about QoL and HRQoL; and (3) how these concepts provide insight into, and promote, health in the context of populations with neurodisability. The hope is to illustrate how a combination of a clear research question, a hypothesis, conceptualization of the required outcomes, and operational definitions of the domains and items of interest, including item mapping, can help to achieve robust methodology and valid findings beyond the required psychometric properties. WHAT THIS PAPER ADDS: The language, content, and the source of perceived health and life issues are clarified. Using the same terms for different constructs, or different terms for the same constructs, creates confusion and hinders outcome research. The challenges of using patient-reported outcomes in neurodisability are addressed., (© 2023 Mac Keith Press.)

Copy number variations (CNVs) are associated with psychiatric and neurodevelopmental disorders (NDDs), and most, including the recurrent 15q13.3 microdeletion disorder, have unknown disease mechanisms. We used a heterozygous 15q13.3 microdeletion mouse model and patient iPSC-derived neurons to reveal developmental defects in neuronal maturation and network activity. To identify the underlying molecular dysfunction, we developed a neuron-specific proximity-labeling proteomics (BioID2) pipeline, combined with patient mutations, to target the 15q13.3 CNV genetic driver OTUD7A. OTUD7A is an emerging independent NDD risk gene with no known function in the brain, but has putative deubiquitinase function. The OTUD7A protein-protein interaction network included synaptic, axonal, and cytoskeletal proteins and was enriched for ASD and epilepsy risk genes (Ank3, Ank2, SPTAN1, SPTBN1). The interactions between OTUD7A and Ankyrin-G (Ank3) and Ankyrin-B (Ank2) were disrupted by an epilepsy-associated OTUD7A L233F variant. Further investigation of Ankyrin-G in mouse and human 15q13.3 microdeletion and OTUD7A L233F/L233F models revealed protein instability, increased polyubiquitination, and decreased levels in the axon initial segment, while structured illumination microscopy identified reduced Ankyrin-G nanodomains in dendritic spines. Functional analysis of human 15q13.3 microdeletion and OTUD7A L233F/L233F models revealed shared and distinct impairments to axonal growth and intrinsic excitability. Importantly, restoring OTUD7A or Ankyrin-G expression in 15q13.3 microdeletion neurons led to a reversal of abnormalities. These data reveal a critical OTUD7A-Ankyrin pathway in neuronal development, which is impaired in the 15q13.3 microdeletion syndrome, leading to neuronal dysfunction. Furthermore, our study highlights the utility of targeting CNV genes using cell type-specific proteomics to identify shared and unexplored disease mechanisms across NDDs., (© 2023. The Author(s).)

Introduction: Researchers have called for innovative tailored interventions to address specific challenges to physical activity (PA) engagement for young people with epilepsy (YPE). Working with YPE and their parents, this study aimed to identify barriers and facilitators to adoption and maintenance of PA among YPE prior to and during the COVID-19 pandemic., Methods: Ten YPE (all female) and their 13 caregivers, and five additional caregivers to males (N = 18; 72% mothers), completed virtual focus group sessions prior to and during the COVID-19 pandemic. Trained Child Life specialists asked questions about barriers and facilitators of PA engagement experienced by YWE, which included a specific focus on the impact of epilepsy., Results: Thematic analysis of the data identified both epilepsy-specific and generic themes that impact PA participation among YPE. These included: (i) epilepsy experience/impact and accommodation; (ii) safety precautions; (iii) concern about seizures; (iv) social connections and acceptance; (v) parent and family support; (vi) intrapersonal self-regulation and motivation; (vii) health benefits; and (viii) key factors in common with all youth., Conclusion: This study provides valuable insight into diverse social-ecological health factors that impact PA participation among YPE from two key stakeholder perspectives (YPE and their caregivers). By understanding these lived experiences, providers can better tailor individual support for YPE and their families to foster and maintain a healthy active lifestyle., Competing Interests: Conflict of interest The authors have no conflict of interest to declare., (Copyright © 2022 The Authors.

Patient and public involvement in health care is considered indispensable in the way we conduct daily pediatric neurology practice, and in the development and utilization of health outcome measurements. This essay examines what meaningful quality evaluations and measurements are, describes the development of approaches to measuring health and outcomes, explores the potential applications of patient-reported outcome measures in pediatric neurology, and identifies opportunities and challenges in using patient-reported outcome measurements in our daily clinical practice. Recent developments have transformed our attitude on how to help children with neurological and developmental conditions and their families: specifically, (1) the recognition of the fundamental rights of children with disabilities; (2) the application of the framework of the International Classification of Functioning, Disability and Health by the World Health Organization that views health from the perspective of both biopsychosocial strengths and functional abilities; (3) the application of qualitative research methodologies to children with neurological conditions and their caregivers to elucidate what they consider essential for their own good health and well-being; and (4) the development of core outcome measurements sets for children and adults with various neurological and developmental conditions. In summary, supporting patients in their role as full partners in clinical care and research enables them to contribute their experiential knowledge and helps ensure that results are relevant and address patient needs, preferences, and priorities. Recognizing the importance of involving young people in their health management decisions has become central in contemporary medicine and needs to be part of the curriculum of all health care professionals., (Copyright © 2022 Elsevier Inc.

This review explores children's self-reported outcome measurements in pediatric neurology. We examine the following questions: (1) What is meant by patient-reported health, functioning, and quality of life outcomes? (2) How can patients express whether the interventions they receive do more good than harm? (3) Why and how should pediatric neurology patients help determine the outcomes of interest? (4) What tools and recommendations are available to evaluate the outcomes of interest? Applying patients' perspectives across the processes of evaluation of medical interventions has become an important expectation. These developments, consistent with current healthcare goals, coincide with the evolution of pediatric neurology into a sophisticated diagnostic-interventional field that aims to prolong survival, decrease impairments and symptoms, and improve patients' well-being - the recognized essential endpoints of interest in all medicine., (© 2021 Mac Keith Press.)

Objective: (1) Examine 24-hour movement guideline adherence among young people with active and inactive epilepsy compared to population norms. (2) Investigate associations between 24-hour movement guideline adherence and mental health disorders among these subpopulations., Methods: Cross-sectional data from the 2016 to 2019 cycles of the National Survey of Children's Health were used. Parental/caregiver reports of movement behaviors (physical activity, screen time, sleep, and sport participation) were used to determine adherence to the 24-hour movement guidelines and associations with mental health disorders for young people with active (n = 663) and inactive epilepsy (n = 526) as well as population norms (n = 49,067) between 6 and 17 years old. Multivariate logistic regression analyses were conducted., Results: Young people with active epilepsy were less likely to meet the 24-hour movement guidelines than population norms, largely driven by below average levels of physical activity guideline adherence. Sport participation was lower among both young people with active and inactive epilepsy; seizure severity and health-related limitations played an influential role. Beneficial associations were generally observed between 24-hour movement guideline adherence and mental health disorders, although for young people with active and inactive epilepsy, there was considerable variability among these relationships., Conclusions: Further dissemination of the International League Against Epilepsy's Task Force on Sports and Epilepsy report can help improve promotion of physical activity and sport participation among young people with active and inactive epilepsy. The relationship between 24-hour movement guideline adherence and mental health disorders is complex among young people with epilepsy and longitudinal research is needed to determine causal links., 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 © 2021 Elsevier Inc.

Vigabatrin (VGB) is approved as monotherapy for pediatric patients with Infantile Spasms (IS). Duration of VGB use should be limited because of the risk of retinal and neurotoxicity, but the optimal length of treatment is unknown. Our study aimed to determine the risk of spasms relapse after 6 months of VGB as first-line therapy in IS patients deemed VGB good responders. The participants were 44 infants with IS who demonstrated both absence of clinical spasms and hypsarrhythmia four weeks after starting VGB, obtained from two cohorts: 29 patients from a multicenter prospective cohort and 15 patients from a retrospective single-center cohort. We divided them post hoc into two groups according to the duration of VGB treatment: 6-month group (n=34) and >6-month group (n=10) and compared outcome between the two groups. No patient in either group had a relapse of spasms. For patients with non-identified etiology (NIE) in the 6 months treatment group, no other seizure types were observed. Late epilepsy, in the form of focal seizures, emerged in only 5/37 patients (3/30 in the 6-month treatment group; 2/7 in the extended treatment group); all within the first 6-9 months after VGB initiation. Our study provides substantial evidence that a shortened VGB course of 6 months could be sufficient to treat and prevent relapse of spasms in children with IS, particularly those with NIE., (Copyright © 2021 British Epilepsy Association.

Objective: To evaluate the extent to which self-esteem mediates the impacts of epilepsy-specific and environmental factors on mental health outcomes in young people with epilepsy., Methods: A prospective cohort of 480 young people with epilepsy and their families participated in five visits over 28 months. We collected data on clinical seizure burden, cognitive comorbidity, peer and parental support, self-esteem, and self-reported mental health symptoms. We used structural equation modeling to specify and test relationships among these constructs simultaneously. Direct, indirect, and total effects were estimated with confidence intervals constructed through bias-corrected bootstrapping., Results: Self-esteem mediated the effects of clinical seizure burden ( β  = 0.23, 95% confidence interval [0.05, 0.42]) and peer support ( β  = -0.15, 95% CI [-0.28, -0.03]) on mental health. There were no mediating effects of parental support ( β  = -0.07, 95% CI [-0.14, 0.00]) or cognitive comorbidity ( β  = -0.01, 95% CI [-0.02, 0.01]) on mental health., Significance: We found evidence that self-esteem mediates the impact that both clinical seizure burden and peer support have on mental health outcomes, indicating that assessment of and interventions targeting self-esteem may be appropriate for young people with epilepsy. Supporting self-esteem could mitigate negative influences on mental health, whether from resistant epilepsy or low peer support., (© 2021 International League Against Epilepsy.)

Introduction: While most paediatric urologists consider patients' quality of life (QOL) important, few actually measure this outcome. Our goal was to assess instruments used in the pediatric urology QOL literature, specifically looking at whether they captured QOL., Methods: We searched MEDLINE and EMBASE for articles with a self-described primary outcome of measuring QOL. All validated QOL instruments in the papers were analyzed by QOL instrument content experts. Instruments were classified as focusing on: Functioning or QOL (Table). The term Functioning focuses on performing activities. QOL captures person's perceptions about their position in life, informed by circumstances, functioning and conditions. QOL instruments were further subdivided into generic QOL, health-related QOL (HRQOL) and disease-specific HRQOL. Only direct patient self-reported QOL instruments were then assessed, since they are the most clinically useful, reliably assessing patients' own perception of their QOL., Results: Forty-three publications met inclusion criteria (published 1999-2019). Most common conditions included urinary incontinence (16, 37.2%) and kidney transplantation (12, 27.9%). Overall, 22 unique instruments purporting to measure QOL were identified. Looking at the concepts measured by each instrument, nine instruments (40.9%) assessed Functioning. Nine instruments (40.9%) measured a combination of Functioning and QOL. Only the remaining 4 instruments (18.2%) assessed strictly QOL. The 13 instruments assessing any QOL focused on generic QOL (n = 4), HRQOL (n = 3) and disease-specific HRQOL (n = 6). Of the subset of four instruments assessing strictly QOL, and not Functioning, all had patient self-reported versions available: two generic QOL instruments (KINDL, KIDSCREEN), one generic HRQOL (DISABKIDS), and one disease-specific HRQOL (QUALAS). Thirteen of 43 studies (30.2%) employed more than one instrument. Thirty-eight studies (88.4%) used an instrument measuring Functioning, with 19 (44.1%) measuring only Functioning, not QOL at all. Twenty-four studies (55.8%) used an instrument measuring actual QOL, although 17 (39.5%) used a combined Functioning/QOL instrument. Only nine (20.9%) used a strictly QOL instrument (strictly HRQOL instruments: 4.7%)., Discussion: We present encouraging evidence of sustained interest in QOL research in pediatric urology and identify areas needing improvement. Selecting appropriate QOL tools requires a working knowledge of their various underlying meanings and purposes. Whether it adequately assess QOL must be considered. We discuss strengths and weaknesses of instruments and a practical approach to QOL instrument selection., Conclusion: Much of pediatric urology is grounded in improving QOL. Unfortunately, most studies published to date focus on Functioning, rather than young people's perception-based QOL. Future QOL studies should ideally employ validated instruments capturing patient-reported QOL., Competing Interests: Conflict of interest The authors have no conflicts of interest relevant to this article to disclose., (Copyright © 2021 Journal of Pediatric Urology Company.

Aim: To evaluate the long-term developmental trajectory of children with infantile spasms (IS) and identify the clinical protective and risk factors associated with their cognitive outcome., Methods: We analyzed the five-year follow-up results of 41 children (13 female) from the previously published cohort (n = 68) recruited in a multicenter randomized controlled trial for 2-years, examining the effect of an adjunctive therapy (Flunarizine) on standardized IS treatment. The children were subsequently monitored in an open-label study for additional 3 years.  The Vineland Adaptive Behavior Scale, second edition, and either the Stanford-Binet Intelligence Scale, Fifth Edition (SB5) or the Bayley Scales of Infant Development, second edition (BSID-II) were used as cognitive outcome measures., Results: Etiology was the strongest predictor of outcome. Children with no identified etiology (NIE) showed a progressive improvement of cognitive functions, mostly occurring between 2 and 5 years post-diagnosis.  Conversely, symptomatic etiology was predictive of poorer cognitive outcome. Developmental delay, other seizure types (before and after IS diagnosis), and persistent electroencephalographic abnormalities following treatment were predictive of poor cognitive outcome., Interpretation: Given the 5-year cognitive improvement, children with IS should undergo a developmental assessment before school entry. Factors influencing their cognitive outcome emphasize the importance of thorough investigation and evidence-based treatment., (Copyright © 2021 British Epilepsy Association.

Objectives: Patient-reported outcomes are increasingly recommended to guide patient care, develop and evaluate interventions, and modify health systems. However, not enough is known about whether and how children and adolescents, as "experts" in their own health and quality of life (QoL), are being engaged in the development of instruments. Our goals in this review were (1) to identify all QoL-related instruments that have included children and/or adolescents in the development of questionnaire content, including identification of themes and items; and (2) to report how this was done; and (3) to highlight those that used qualitative methods., Methods: MEDLINE and Embase were searched for child- or adolescent-completed QoL-related instruments, supplemented by hand-searching of relevant reviews until 2020. Original development papers were identified and retrieved when possible, from which instrument characteristics and details of qualitative development methods were extracted., Results: We identified 445 instruments, of which 88 used qualitative methods for content development. Interviews and focus groups were the most common methods. A variety of play techniques were used to engage the child and adolescent participants. The specific criteria for the inclusion of children and adolescents (age, developmental stage, duration, and nonclinical location) varied considerably., Conclusions: Researchers frequently involve children and adolescents in qualitative methods when developing QoL-related measures; however, there is little information about the methods used. Better reporting of methodology, improved dissemination of methods guidelines, and research into optimal ways of including children and adolescents in the process of instrument development would be useful., (Copyright © 2020 ISPOR–The Professional Society for Health Economics and Outcomes Research.

Purpose: Qualitative research studies deepen our understanding of growing up with epilepsy but are limited to the singular perspective of children or their parents at one point in childhood. A more complete view requires multiple perspectives and narrative accounts that represent development from early childhood to young adulthood. Thematic study of life narratives of 7 young people and at least one person within their families were interviewed separately (15 participants) for two interviews each (30 interviews). The objective was to obtain narratives of the life experiences, the attributions of those experiences, and crucial periods relating to quality of life (QOL) with no apriori assumptions that their lives were shaped by epilepsy. Themes were formed inductively from subthemes and codes were created based on the constant comparative method by two interviewers who iteratively co-coded the data., Results: Themes emerging from the data: "Story of My Health," "Growing by Doing," "To Adapt or Not to Adapt," "Supports and Challenges," "Parent World," and "Looking in and Out, Forward and Back", often included components of seizure and epilepsy experiences but also mirrored life challenges of growing up in general. The only exclusively epilepsy-specific theme: "To Adapt or Not to Adapt", was about the challenges and solutions for dealing with the uncertainty caused by seizures and potential isolation that results from others' reactions., Conclusions: There were a range of experiences related to QOL described by participants growing up with epilepsy. The 'ingredients' of a good life (e.g., social and self-acceptance) were consistent with QOL research for general populations, although these were often expressed as more difficult to attain when growing up with epilepsy., Competing Interests: Declaration of interests The authors have no conflicts of interest to declare., (Copyright © 2020 Elsevier Inc.

Epilepsy of infancy with migrating focal seizures (EIMFS), one of the most severe developmental and epileptic encephalopathy syndromes, is characterized by seizures that migrate from one hemisphere to the other. EIMFS is genetically heterogeneous with 33 genes. We report five patients with EIMFS caused by recessive BRAT1 variants, identified via next generation sequencing. Recessive pathogenic variants in BRAT1 cause the rigidity and multifocal seizure syndrome, lethal neonatal with hypertonia, microcephaly, and intractable multifocal seizures. The epileptology of BRAT1 encephalopathy has not been well described. All five patients were profoundly impaired with seizure onset in the first week of life and focal seizure migration between hemispheres. We show that BRAT1 is an important recessive cause of EIMFS with onset in the first week of life, profound impairment, and early death. Early recognition of this genetic aetiology will inform management and reproductive counselling., (© 2019 Mac Keith Press.)

Aim: To compare: (1) self- and proxy-reported quality of life (QoL) in adolescents with epilepsy, cerebral palsy (CP), both epilepsy and CP, and a representative general population sample; and (2) parental stress between parents of adolescents with epilepsy, CP, or both epilepsy and CP., Method: This was a cross-sectional observational study with 496 adolescents with epilepsy, 699 with CP, 192 with both CP and epilepsy, and 15 396 from the general population, assessed with the KIDSCREEN-52 and Parenting Stress Index (PSI)., Results: All KIDSCREEN-52 domains showed statistically significant differences across groups. The epilepsy population showed clinically better scores for 'school environment' than the general population (Cohen's d=0.62). Parents scored adolescents with CP lower than adolescents with epilepsy or general populations on 'physical health' (d=0.57, d=0.55) and 'social-support and peers' (d=0.82, d=0.91). Parents of adolescents with CP scored them lower than parents of the epilepsy group on 'autonomy' (d=0.62). Parents of adolescents with epilepsy scored them lower on 'mood and emotions' (d=0.52) and 'social acceptance' (d=0.66) than the general population. PSI scores were better for parents of adolescents with CP than for parents of adolescents with epilepsy (d=2.12, d=2.70, d=3.35, d=1.67)., Interpretation: Adolescents with epilepsy or CP self-report equal or better QoL than the general adolescent population, which should comfort families and allow clinicians to address parental concerns., What This Paper Adds: Adolescents with epilepsy, with or without cerebral palsy (CP), self-reported better school environment than adolescents in the general population. Proxy quality of life (QoL) results showed clinically important differences across groups in 6 out of 10 domains of the KIDSCREEN-52. Proxy-reported results showed poorer QoL scores for adolescents with epilepsy or CP than the general population. Parental stress level was lower in parents of children with CP or both CP and epilepsy, than in those with only epilepsy., (© 2020 Mac Keith Press.)

Aim: To examine self- and proxy-reported symptoms of depression in children with epilepsy., Method: This was a prospective longitudinal cohort study of children with epilepsy. Participants were treated at six Canadian tertiary-care centers and followed over 28 months with repeated assessments of child self-reported symptoms of depression using the Children's Depression Inventory Short-Form (CDI-S). Trajectories of symptoms of depression were estimated using linear mixed effects (LME) modeling., Results: At baseline, 477 children had complete data (mean age [SD] 11y 5mo [2y 1mo], range 7y 7mo-15y 1mo; 234 females, 243 males). Mean CDI-S T score at baseline was 45.7 (SD=7.5) and at 28 months was 44.9 (SD=8.2), both were within the 'average' range. Results from LME modeling revealed mean raw CDI-S score of 1.897, corrected for age 10 years (corresponding to T scores slightly below the normed mean of 50), with no significant change over three measurements (slope=-0.113, p=0.135), indicating that CDI-S scores were stable over 28 months. Children with high initial CDI-S scores had lower subsequent scores, as demonstrated by the correlation of -0.827 between intercept and slope (p<0.001). Parents reported comparable findings., Interpretation: Self- and proxy-reported symptoms of depression were generally low and stable over an extended follow-up period. Normalization of scores was seen upon repeated assessment, even in children with higher scores of symptoms of depression at one point. These findings speak to the value and importance of repeated assessment over time., What This Paper Adds: In children with epilepsy, self- and proxy-reported symptoms of depression were generally low and stable over 28 months. The trajectory of symptoms of depression was not associated with seizure severity, whether considering the frequency or type of seizures. Parents' reports of symptoms of depression were comparable to the children's self-evaluations., (© 2019 Mac Keith Press.)

Aim: To: (1) explore how young people with epilepsy spend time on physical activity, screen-time, and sleep in a 24-hour period; (2) compare these findings to young people without epilepsy; and (3) evaluate the findings relative to the Canadian 24-hour movement guidelines for children and youth., Method: The study is based on Canadian data from the 2013 to 2014 'Health Behaviour in School-aged Children study' (HBSC), a cross-sectional sample of young people aged 10 to 17 years. Three groups participated: 163 young people with epilepsy, 3613 young people with non-neurological conditions, and 18 339 population norms. Self-reported activity data were compared across groups., Results: Demographics were similar across groups. Young people with epilepsy spent 5.8 hours per week on moderate-to-vigorous physical activity versus 5.6 hours per week in population norms; 32% met the recommended 1 hour or more per day. Screen-time was 8.7 hours per day versus 7.4 hours per day in population norms; only 5.4% met the 2 hours or less per day recommendation. Sleep duration was 10.2 hours per day versus 9.8 hours per day in population norms, and 50.7% met the recommendation. Overall, 25.7% of young people with epilepsy did not meet any of the guidelines, 60.5% met one, 13.5% met two, and 0.3% met all three recommendations; whereas 2.8% of population norms and 2% of young people with non-neurological conditions met all three recommendations., Interpretation: These data could inform future interventions and alert policy-makers, health care professionals, parents, educators, and advocacy-groups to the low adherence of young people with epilepsy with Canadian guidelines and their risk for poor health., What This Paper Adds: Young people with epilepsy adhere poorly to Canadian guidelines for daily sleep duration, physical activity, and sedentary screen time. Young people with epilepsy accumulate more screen-time than those with non-neurological conditions or population norms., (© 2019 Mac Keith Press.)

Objectives: To study the extent to which parents are able to serve as true proxies for their children with epilepsy using a more granular approach than has been found in any study to date., Methods: Proxy resemblance to the child was based on discrepancy in z-centered child minus parent scores of matching quality-of-life (QOL) domains for 477 dyads. Latent class mixed models (LCMMs) were built, with child's age as the independent variable for epilepsy-specific and generic QOL. Data were obtained from the QUALITÉ Canadian cohort, which recruited children with epilepsy aged 8 to 14 years at baseline and their parents., Results: Both epilepsy-specific and generic LCMMs produced latent classes representing proxies that were overly positive, overly negative, or in agreement relative to their children with posterior probabilities of 79% to 84%. The "agreement" classes had N = 411 and N = 349 in the epilepsy-specific and generic LCMMs, respectively. The epilepsy-specific LCMM had a small unique class of N = 5 with a posterior probability of 88% called "growing discrepancy.", Conclusions: Most parents of children with epilepsy can serve as valid proxies for their children on QOL scales. Poorer parental adaptation is more related to overly negative proxies, whereas low peer support from the child's perspective is more related to overly positive proxies., (Copyright © 2019 ISPOR–The Professional Society for Health Economics and Outcomes Research.

Purpose: This study examined whether increasing physical activity (PA) through 6 months of behavioral counseling positively influenced depressive symptoms and quality of life (QoL) over 12 months among children with epilepsy (CWE)., Methods: A longitudinal multisite randomized controlled trial (RCT) was conducted with 8-14-year-old children with active epilepsy. Participants wore a pedometer to track daily PA and completed 3 measures at 4 time points to examine depressive symptoms and QoL. Stratified by site and activity level, participants were randomized to an intervention or control group. The 6-month intervention included 11 behavioral counseling sessions targeting self-regulation of PA. To assess the associations among PA, depression scores, and QoL, primary analysis involved mixed-effects models., Results: We recruited 122 CWE, of whom 115 were randomized (M age  = 11 ± 2; 50% female) and included in the analysis. The intervention did not increase PA in the treatment compared with the control group. No differences were found between groups over time during the subsequent 6 months, where PA decreased among all participants. Results did not show differences between the groups and over time for measures of depressive symptoms and QoL., Significance: The intervention did not improve or sustain PA levels over 12 months. Both groups demonstrated declines in PA over one year, but there were no changes in depression scores or QoL. As most participants were already nearly reaching the Canadian average of step counts of children their age, with a baseline daily step count of over 9000, there may be a challenge for further increasing PA over a longer period., (Copyright © 2019 Elsevier Inc.

Purpose: We aimed to explore (i) the impact that a motivated walking program had on youth with epilepsy and (ii) the facilitators and barriers to implementing and sustaining the program., Methods: Data were gathered using semi-structured interviews with the intervention group of a randomized controlled trial to study the effect of enhanced physical activity on youth with epilepsy. Participants had active epilepsy and were 8-14 years at recruitment. All wore an activity tracker for a year and received coaching via phone calls during the first six months to encourage reaching a step goal, which they then attempted to maintain independently for the following six months. Nine participants and one parent per child were separately interviewed at six months. Eleven participants including the original nine, and one parent per youth, were interviewed at twelve months. Data collection and analysis used a phenomenological research framework and coded the data according to the International Classification of Functioning, Disability and Health (the ICF). This was done in order to capture all relevant impacts of the intervention., Results: Physical activity was associated with benefits in all components of the ICF. Changes in personal factors such as improved attitude, confidence, and insight into activity were emphasized. Parents also experienced personal benefits as a result of their child engaging in the program., Conclusions: Physical activity had positive effects in many aspects of the lives of the participants and their parents. The ICF was a relatively useful and effective system for coding qualitative research. These findings should assist in development of future exercise programs., (Copyright © 2018 Elsevier Inc.

In the 21st century, clinicians are expected to listen to, and understand their patients' views about, their conditions and the effects that these conditions have on their functioning, values, life goals, and welfare. The goals of this review are as follows: (i) to inform, update, and guide clinicians caring for children with epilepsy about developments in the content and new methods of research on patient-reported outcomes, quality of life, and functioning; and (ii) to discuss the value of using these concepts to explore the impact of diverse interventions that are implemented in daily practice. Drawing on the literature and our program of research over the past two decades, we focus on our current understanding of a variety of health concepts and recently acquired knowledge about their significance for the lives of patients and their families. We discuss the advantages of measuring patient-reported outcomes that tell us what is important to patients. We advise on what characteristics to look for when choosing a patient-reported measure, and the relevance of these considerations. In addition, we address gaps in research knowledge and the causes of confusion that have limited their use in our daily clinical practice., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Rolandic epilepsy (RE) is the most common focal epilepsy in childhood. To date no hypothesis-free exome-wide mutational screen has been conducted for RE and atypical RE (ARE). Here we report on whole-exome sequencing of 194 unrelated patients with RE/ARE and 567 ethnically matched population controls. We identified an exome-wide significantly enriched burden for deleterious and loss-of-function variants only for the established RE/ARE gene GRIN2A. The statistical significance of the enrichment disappeared after removing ARE patients. For several disease-related gene-sets, an odds ratio >1 was detected for loss-of-function variants.

Background: Ogden syndrome is a rare X-linked disorder caused by pathogenic variants in the NAA10 gene. This syndrome, reported in just over 20 children, has been associated with dysmorphic features, failure to thrive, developmental impairments, hypotonia, and cardiac arrhythmias., Patient Description: We describe a 14-year-old girl who presented in infancy with hypotonia, global developmental delay, and dysmorphic features. She later developed autism spectrum disorder, epileptic encephalopathy, extrapyramidal signs, early morning lethargy with hypersomnolence, and hypertension with left ventricular hypertrophy. Magnetic resonance imaging showed a thin corpus callosum and progressive white matter loss. Whole exome sequencing identified a de novo pathogenic variant in the NAA10 gene (c.247C>T, p.R83C). Much of her early presentation was in keeping with what has been previously described with Ogden syndrome., Conclusions: We have identified additional evolving neurological impairments in this, to date, oldest documented girl with Ogden syndrome. We recommend screening patients with Ogden syndrome for these newly identified features of early life trajectories to guide management., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Objective: To describe the developmental trajectories of quality of life (QoL) in a large cohort of children with epilepsy, and to assess the relative contribution of clinical, psychosocial, and sociodemographic variables on QoL trajectories., Methods: Five assessments during a 28-month prospective cohort study were used to model trajectories of QoL. Participants were recruited with their parents from six Canadian tertiary centers. A convenience sample of 506 children aged 8-14 years with epilepsy and without intellectual disability or autism spectrum disorder were enrolled. A total of 894 children were eligible and 330 refused participation. Participating children were, on average, 11.4 years of age, and 49% were female. Nearly one third (32%) had partial seizures. At baseline, 479 and 503 child- and parent-reported questionnaires were completed. In total, 354 children (74%) and 366 parents (73%) completed the 28-month follow-up. QoL was measured using the child- and parent-reported version of the Childhood Epilepsy QoL scale (CHEQOL-25)., Results: Child-reported QoL was fitted best by a six-class model and parent-reported QoL by a five-class model. In both models, trajectories remained either stable or improved over 28 months. Of these children, 62% rated their QoL as high or moderately high, defined as at least one standard deviation above the average CHEQOL-25 score. Greater family, classmate, and peer social support, fewer symptoms of child and parent depression, and higher receptive vocabulary were identified as the most robust predictors of better QoL (all p < 0.001)., Significance: Most children with epilepsy and their parents reported relatively good QoL in this first joint self- and proxy-reported trajectory study. Findings confirm the heterogeneous QoL outcomes for children with epilepsy and the primary importance of psychosocial factors rather than seizure and AED-specific factors in influencing QoL. These predictors that are potentially amenable to change should now be the focus of specific intervention studies., (Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.)

Our goals in this reflection are to (i) identify the ethical dimensions inherent in any clinical encounter and (ii) bring to the forefront of our pediatric neurology practice the myriad of opportunities to explore and learn from these ethical questions. We highlight specifically Beauchamp and Childress's principles of biomedical ethics. We use the terms ethics in common clinical practice and an ethical lens to remind people of the ubiquity of ethical situations and the usefulness of using existing ethical principles to analyze and resolve difficult situations in clinical practice. We start with a few common situations with which many of us tend to struggle. We describe what we understand as ethics and how and why developments in technology, novel potential interventions, policies, and societal perspectives challenge us to think about and debate ethical issues. Individual patients are not a singular population; each patient has their own unique life situations, culture, goals, and expectations that need to be considered with a good dose of humanity and humility. We believe that using an ethical lens-by which we mean making an explicit effort to identify and consider these issues openly-will help us to achieve this goal in practice, education, and research.

Background: This communication examines the expanding phenotypes of the MECP2 C-terminal atypical Rett syndromes in males and their affected carrier mothers., Descriptions: We describe three males with normal karyotypes who presented with congenital evolving complex neurodevelopmental encephalopathies with multifaceted symptomatology of hypotonia, epilepsy, ataxia, spasticity, movement disorders, behavioral issues, severe intellectual impairment, and communication skills, and a protracted regression phase followed by stabilization. These phenotypes did not prompt us to identify atypical Rett syndrome early in childhood., Results: Genetic analysis identified the two brothers with C-terminal truncation and the third male with C-terminal missense mutations. These mutations were inherited from their mothers, both of whom had incompletely characterized modest intellectual, mental health, social, and gastrointestinal impairments. Neither was independently able to care properly for their son(s)., Conclusions: Mutations of the MECP2 gene should be considered early in males with hypotonia, developmental delay, profound intellectual impairment, and seizures, associated with a mother with psychosocial, cognitive, and gastrointestinal impairments. Counseling and supporting mildly affected mothers requires both medical and social efforts., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Fifty years ago Andreas Rett first described in great detail what came to be known as "Rett syndrome." Understanding girls and women with this syndrome and their families helped in many ways to revolutionize modern neurodevelopmental medicine. For some people the identification of the genetic underpinning of the syndrome and the ongoing biological research into this condition represented the peak of the scientific accomplishments in Rett syndrome. For others, it was developments in clinical research methodologies that were especially important. Above all, the patient- and family-oriented empathetic and collaborative approach to care by professionals collaborating with families has led to immense achievements, both scientific and humanistic., Aim: The aim of this narrative was to describe the medical and personal life story of a young woman with Rett syndrome and to offer a history that highlights developments in the unraveling of this condition from its initial recognition to our current understanding., Conclusion: We believe that much can be learned from the humanistic style of care provision combined with the best possible level of assisted autonomy and life enjoyment of the young woman with Rett syndrome. In addition, the approach to collaborative research by dedicated and often charitable leaders in the field can teach us many important lessons about the ethics of clinical and health services research., (Copyright © 2016 Elsevier Inc.

Introduction: Participation in extracurricular activities creates opportunities for children to foster friendships, promote a sense of belonging, and improve physical and mental well-being. The objective of this study was to determine the relationship(s) of personal factors, seizure variables, and social supports with extracurricular participation in children with epilepsy (CWE)., Methods: Baseline analysis of the QUALITÉ longitudinal study cohort of children aged 8-14 years (N=426) was conducted. Variables hypothesized to be related to the participation of CWE were classified using the International Classification of Functioning, Disability and Health according to body functions (presence of generalized tonic-clonic seizures in the past month, on/off AEDs, and seizure severity), environmental factors (perceived social support from parents and friends), and personal factors (sex, age, family structure, and family income). Analysis of variables related to extracurricular participation was conducted with regression modeling., Results: Personal factors of age, gender, and family structure as well as body function variables of generalized tonic-clonic seizures and seizure severity were found to be the most important to extracurricular participation based on how frequently they were included in the final models (16/16 and 13/16 times, respectively). When parental support was found to be related to participation, the association was negative in 6 out of 16 models., Discussion: The personal factors that are related to extracurricular participation among children with epilepsy mirror samples based on the general population, although seizures also play an important role. The relationship between perceived parental support and actual participation levels warrants further exploration., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Our objective was to compare the quality of life (QoL) of children with epilepsy to that of typical children and children with cerebral palsy (CP). We measured self- and proxy-reported QoL of children with epilepsy and contrasted that with data for typical children (European KIDSCREEN project) and children with CP (SPARCLE study). Children ages 8-12 years with epilepsy were recruited from six Canadian sites. Same-aged children with CP and children in the general population aged 8-11 years came from several European countries. All participants completed the KIDSCREEN-52 questionnaire. Our results showed no clinically important differences (>0.5 SD) between self-reported QoL in 345 children with epilepsy compared with 489 children with CP or 5950 children in the general population. However, parents reported clinically important differences between the epilepsy and the other groups in five KIDSCREEN-52 domains. Compared with the CP group, parents of children with epilepsy reported better QoL in physical well-being (Cohen d=0.81), social support (d=0.80), and autonomy (d=0.72). Parents reported poorer QoL in the domains of mood and emotions compared with both contrast groups (d=-0.72 and d=-0.53), and in the domain of bullying compared with the CP group (d=-0.51). Families should find comfort in the results, which indicate that children with epilepsy do not perceive any important differences in QoL compared with their typical peers. The comparisons of parental reports detect their group-specific observations and worries that need to be addressed by the health-care providers and may require specifically designed assessment batteries followed by appropriate interventions., (Copyright © 2015 Elsevier Inc.

Background: As is often the case for rare diseases, the number of published reviews and case reports of glucose transporter type I deficiency (G1D) approaches or exceeds that of original research. This can indicate medical interest, but also scientific stagnation., Methods: In assessing this state of affairs here, we focus not on what is peculiar or disparate about G1D, but on the assumptions that have reigned thus far undisputed, and critique them as a potential impediment to progress. To summarize the most common G1D phenotype, we trace the 25-year story of G1D in parallel with the natural history of one of two index patients, identified in 1990 by one of us (G.M.R.) and brought up to date by the other (J.M.P.) while later examining widely repeated but little-scrutinized statements. Among them are those that pertain to assumptions about brain fuels; energy failure; cerebrospinal glucose concentration; the purpose of ketogenic diet; the role of the defective blood-brain barrier; genotype-phenotype correlations; a bewildering array of phenotypes; ictogenesis, seizures, and the electroencephalograph; the use of mice to model the disorder; and what treatments may and may not be expected to accomplish., Results: We reach the forgone conclusion that the proper study of mankind-and of one of its ailments (G1D) -is man itself (rather than mice, isolated cells, or extrapolated inferences) and propose a framework for rigorous investigation that we hope will lead to a better understanding and to better treatments for this and for rare disorders in general., Conclusions: These considerations, together with experience drawn from other disorders, lead, as a logical consequence, to the nullification of the view that therapeutic development (i.e., trials) for rare diseases could or should be accelerated without the most vigorous scientific scrutiny: trial and error constitute an inseparable couple, such that, at the present time, hastening the former is bound to precipitate the latter., (Copyright © 2015 Elsevier Inc.
