RESUMO
Background: Children with chronic diseases have been reported to participate in less regular physical activity (PA) than peers without chronic diseases; and less than recommended in guidelines. Sheffield Children's Foundation Trust (SCFT) is an Active Hospitals pilot site, exploring options to facilitate PA for all children. One option is collaboration with Junior Parkrun: a free, weekly 2 km running event for children. The team investigated whether Junior Parkrun was of interest to guardians of children attending SCFT to increase PA. Aims: This patient and public involvement survey assessed perceptions of PA for children attending SCFT according to their accompanying guardians. This will inform a possible collaboration between SCFT and Junior Parkrun. Methods: A three-part, 14-question survey was developed, including demographics (age, ethnicity, postcode); perceptions of PA (barriers and facilitators); PA behaviours self-reported on Likert scales; and perceptions of Junior Parkrun. Guardians were asked whether they and their child would be interested in attending Junior Parkrun with SCFT staff support. This was distributed to guardians of children attending outpatient appointments. Results: 126 guardians responded. The average age of child was 10 years 10 months. 29.1% of guardians supported daily PA for their child. Almost half of respondents reported their child would be interested in attending Junior Parkrun. Of those not interested, the most common reason was travel. Conclusion: The findings highlighted PA barriers perceived by guardians, and identified that almost half of respondents would be interested in attending Junior Parkrun. A collaboration between Junior Parkrun and SCFT could be explored.
RESUMO
OBJECTIVES: Childhood hearing loss has well-known lifelong consequences. Certain rural populations are at higher risk for infection-related hearing loss. For Alaska Native children, historical data on hearing loss prevalence suggest a higher burden of infection-related hearing loss, but updated prevalence data are urgently needed in this high-risk population. DESIGN: Hearing data were collected as part of two school-based cluster-randomized trials in 15 communities in rural northwest Alaska over two academic years (2017-2019). All enrolled children from preschool to 12th grade were eligible. Pure-tone thresholds were obtained using standard audiometry and conditioned play when indicated. The analysis included the first available audiometric assessment for each child (n = 1634 participants, 3 to 21 years), except for the high-frequency analysis, which was limited to year 2 when higher frequencies were collected. Multiple imputation was used to quantify the prevalence of hearing loss in younger children, where missing data were more frequent due to the need for behavioral responses. Hearing loss in either ear was evaluated using both the former World Health Organization (WHO) definition (pure-tone average [PTA] > 25 dB) and the new WHO definition (PTA ≥ 20 dB), which was published after the study. Analyses with the new definition were limited to children 7 years and older due to incomplete data obtained on younger children at lower thresholds. RESULTS: The overall prevalence of hearing loss (PTA > 25 dB; 0.5, 1, 2, 4 kHz) was 10.5% (95% confidence interval [CI], 8.9 to 12.1). Hearing loss was predominately mild (PTA >25 to 40 dB; 8.9%, 95% CI, 7.4 to 10.5). The prevalence of unilateral hearing loss was 7.7% (95% CI, 6.3 to 9.0). Conductive hearing loss (air-bone gap of ≥ 10 dB) was the most common hearing loss type (9.1%, 95% CI, 7.6 to 10.7). Stratified by age, hearing loss (PTA >25 dB) was more common in children 3 to 6 years (14.9%, 95% CI, 11.4 to 18.5) compared to children 7 years and older (8.7%, 95% CI, 7.1 to 10.4). In children 7 years and older, the new WHO definition increased the prevalence of hearing loss to 23.4% (95% CI, 21.0 to 25.8) compared to the former definition (8.7%, 95% CI, 7.1 to 10.4). Middle ear disease prevalence was 17.6% (95% CI, 15.7 to 19.4) and was higher in younger children (23.6%, 95% CI, 19.7 to 27.6) compared to older children (15.2%, 95% CI, 13.2 to 17.3). High-frequency hearing loss (4, 6, 8kHz) was present in 20.5% (95% CI, 18.4 to 22.7 [PTA >25 dB]) of all children and 22.8% (95% CI, 20.3 to 25.3 [PTA >25 dB]) and 29.7% (95% CI, 27.0 to 32.4 [PTA ≥ 20 dB]) of children 7 years and older (limited to year 2). CONCLUSIONS: This analysis represents the first prevalence study on childhood hearing loss in Alaska in over 60 years and is the largest cohort with hearing data ever collected in rural Alaska. Our results highlight that hearing loss continues to be common in rural Alaska Native children, with middle ear disease more prevalent in younger children and high-frequency hearing loss more prevalent with increasing age. Prevention efforts may benefit from managing hearing loss type by age. Lastly, continued research is needed on the impact of the new WHO definition of hearing loss on field studies.

BACKGROUND: Cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) is a well established therapy in patients with reduced left ventricular ejection fraction (LVEF), heart failure, and wide QRS or expected frequent ventricular pacing. Left bundle branch area pacing (LBBAP) has recently been shown to be a safe alternative to BVP. OBJECTIVES: The aim of this study was to compare the clinical outcomes between BVP and LBBAP among patients undergoing CRT. METHODS: This observational study included patients with LVEF ≤35% who underwent BVP or LBBAP for the first time for Class I or II indications for CRT from January 2018 to June 2022 at 15 international centers. The primary outcome was the composite endpoint of time to death or heart failure hospitalization (HFH). Secondary outcomes included endpoints of death, HFH, and echocardiographic changes. RESULTS: A total of 1,778 patients met inclusion criteria: 981 BVP, 797 LBBAP. The mean age was 69 ± 12 years, 32% were female, 48% had coronary artery disease, and mean LVEF was 27% ± 6%. Paced QRS duration in LBBAP was significantly narrower than baseline (128 ± 19 ms vs 161 ± 28 ms; P < 0.001) and significantly narrower compared to BVP (144 ± 23 ms; P < 0.001). Following CRT, LVEF improved from 27% ± 6% to 41% ± 13% (P < 0.001) with LBBAP compared with an increase from 27% ± 7% to 37% ± 12% (P < 0.001) with BVP, with significantly greater change from baseline with LBBAP (13% ± 12% vs 10% ± 12%; P < 0.001). On multivariable regression analysis, the primary outcome was significantly reduced with LBBAP compared with BVP (20.8% vs 28%; HR: 1.495; 95% CI: 1.213-1.842; P < 0.001). CONCLUSIONS: LBBAP improved clinical outcomes compared with BVP in patients with CRT indications and may be a reasonable alternative to BVP.

OBJECTIVES: Diagnostic accuracy was evaluated for various screening tools, including mobile health (mHealth) pure-tone screening, tympanometry, distortion product otoacoustic emissions (DPOAE), and inclusion of high frequencies to determine the most accurate screening protocol for identifying children with hearing loss in rural Alaska where the prevalence of middle ear disease is high. DESIGN: Hearing screening data were collected as part of two cluster randomized trials conducted in 15 communities in rural northwest Alaska. All children enrolled in school from preschool to 12th grade were eligible. Analysis was limited to data collected 2018 to 2019 (n = 1449), when both trials were running and measurement of high frequencies were included in the protocols. Analyses included estimates of diagnostic accuracy for each screening tool, as well as exploring performance by age and grade. Multiple imputation was used to assess diagnostic accuracy in younger children, where missing data were more prevalent due to requirements for conditioned responses. The audiometric reference standard included otoscopy, tympanometry, and high frequencies to ensure detection of infection-related and noise-induced hearing loss. RESULTS: Both the mHealth pure-tone screen and DPOAE screen performed better when tympanometry was added to the protocol (increase in sensitivity of 19.9%, 95% Confidence Interval (CI): 15.9 to 24.1 for mHealth screen, 17.9%, 95% CI: 14.0 to 21.8 for high-frequency mHealth screen, and 10.4%, 95% CI: 7.5 to 13.9 for DPOAE). The addition of 6 kHz to the mHealth pure-tone screen provided an 8.7 percentage point improvement in sensitivity (95% CI: 6.5 to 11.3). Completeness of data for both the reference standard and the mHealth screening tool differed substantially by age, due to difficulty with behavioral testing in young children. By age 7, children were able to complete behavioral testing, and data indicated that high-frequency mHealth pure-tone screen with tympanometry was the superior tool for children 7 years and older. For children 3 to 6 years of age, DPOAE plus tympanometry performed the best, both for complete data and multiply imputed data, which better approximates accuracy for children with missing data. CONCLUSIONS: This study directly evaluated pure-tone, DPOAE, and tympanometry tools as part of school hearing screening in rural Alaskan children (3 to 18+ years). Results from this study indicate that tympanometry is a key component in the hearing screening protocol, particularly in environments with higher prevalence of infection-related hearing loss. DPOAE is the preferred hearing screening tool when evaluating children younger than 7 years of age (below 2nd grade in the United States) due to the frequency of missing data with behavioral testing in this age group. For children 7 years and older, the addition of high frequencies to pure-tone screening increased the accuracy of screening, likely due to improved identification of hearing loss from noise exposure. The lack of a consistent reference standard in the literature makes comparing across studies challenging. In our study with a reference standard inclusive of otoscopy, tympanometry, and high frequencies, less than ideal sensitivities were found even for the most sensitive screening protocols, suggesting more investigation is necessary to ensure screening programs are appropriately identifying noise- and infection-related hearing loss in rural, low-resource settings.

Objective: This study evaluated the Hearing Environments and Reflection on Quality of Life (HEAR-QL) questionnaire in rural Alaska, including an addendum crafted through community feedback to reflect the local context. The objectives were to assess whether HEAR-QL score was inversely correlated with hearing loss and middle ear disease in an Alaska Native population. Methods: The HEAR-QL questionnaires for children and adolescents were administered as part of a cluster randomized trial in rural Alaska from 2017 to 2019. Enrolled students completed an audiometric evaluation and HEAR-QL questionnaire on the same day. A cross-sectional evaluation of questionnaire data was utilized. Results: A total of 733 children (ages 7-12 years) and 440 adolescents (ages ≥13 years) completed the questionnaire. Median HEAR-QL scores were similar among children with and without hearing loss (Kruskal-Wallis, p = .39); however, adolescent HEAR-QL scores significantly decreased with increasing hearing loss (p < .001). Median HEAR-QL scores were significantly lower in both children (p = .02) and adolescents (p < .001) with middle ear disease compared with those without. In both children and adolescents, the addendum scores were strongly correlated with total HEAR-QL score (ρSpearman = 0.72 and 0.69, respectively). Conclusions: The expected negative association between hearing loss and HEAR-QL score was observed in adolescents. However, there was significant variability that could not be explained by hearing loss, and further investigation is warranted. The expected negative association was not observed in children. HEAR-QL scores were associated with middle ear disease in both children and adolescents, making it potentially valuable in populations where the prevalence of ear infections is high. Level of Evidence: Level 2 Clinicaltrials.gov registration numbers: NCT03309553.
RESUMO
Pediatric headache is a common condition with significant impact on quality of life and ability to function in academic, social, and extracurricular activities. Most pediatric patients seen in primary care and neurology clinics with headache have primary headache disorders. Diagnosis is largely based on clinical history. Imaging is rarely needed in the absence of red flag features. Careful diagnosis is important to guide appropriate treatment. Treatment focuses on a biopsychosocial model integrating lifestyle, pharmacologic and nonpharmacologic treatment modalities. As few therapies are approved in the pediatric population, treatments are often used off-label based on evidence extrapolated from adult studies. Outcomes vary over time but are generally favorable when headache disorders are diagnosed promptly and managed in a multidisciplinary setting.

OBJECTIVE: Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy. We examined the utility of circulating tumor DNA (ctDNA) as a prognostic biomarker for EOC by assessing its relationship with patient outcome and CA-125, pre-surgically and during post-treatment surveillance. METHODS: Plasma samples were collected from patients with stage I-IV EOC. Cohort A included patients with pre-surgical samples (N = 44, median follow-up: 2.7 years), cohort B and C included: patients with serially collected post-surgically (N = 12) and, during surveillance (N = 13), respectively (median follow-up: 2 years). Plasma samples were analyzed using a tumor-informed, personalized multiplex-PCR NGS assay; ctDNA status and CA-125 levels were correlated with clinical features and outcomes. RESULTS: Genomic profiling was performed on the entire cohort and was consistent with that seen in TCGA. In cohort A, ctDNA-positivity was observed in 73% (32/44) of presurgical samples and was higher in high nuclear grade disease. In cohort B and C, ctDNA was only detected in patients who relapsed (100% sensitivity and specificity) and preceded radiological findings by an average of 10 months. The presence of ctDNA at a single timepoint after completion of surgery +/- adjuvant chemotherapy and serially during surveillance was a strong predictor of relapse (HR:17.6, p = 0.001 and p < 0.0001, respectively), while CA-125 positivity was not (p = 0.113 and p = 0.056). CONCLUSIONS: The presence of ctDNA post-surgically is highly prognostic of reduced recurrence-free survival. CtDNA outperformed CA-125 in identifying patients at highest risk of recurrence. These results suggest that monitoring ctDNA could be beneficial in clinical decision-making for EOC patients.

Low-income urban communities in the United States commonly lack ready access to healthy foods. This is due in part to a food distribution system that favors the provision of high-fat, high-sugar, high-sodium processed foods to small retail food stores, and impedes their healthier alternatives, such as fresh produce. The Baltimore Urban food Distribution (BUD) study is a multilevel, multicomponent systems intervention that aims to improve healthy food access in low-income neighborhoods of Baltimore, Maryland. The primary intervention is the BUD application (app), which uses the power of collective purchasing and delivery to affordably move foods from local producers and wholesalers to the city's many corner stores. We will implement the BUD app in a sample of 38 corner stores, randomized to intervention and comparison. Extensive evaluation will be conducted at each level of the intervention to assess overall feasibility and effectiveness via mixed methods, including app usage data, and process and impact measures on suppliers, corner stores, and consumers. BUD represents one of the first attempts to implement an intervention that engages multiple levels of a local food system. We anticipate that the app will provide a financially viable alternative for Baltimore corner stores to increase their stocking and sales of healthier foods, subsequently increasing healthy food access and improving diet-related health outcomes for under-resourced consumers. The design of the intervention and the evaluation plan of the BUD project are documented here, including future steps for scale-up. Trial registration #: NCT05010018.

BACKGROUND AND OBJECTIVES: Children and adolescents with chronic migraine who have continuous headache may have high levels of headache-related disability but have largely been excluded from clinical trials. Understanding patient-valued treatment outcomes may facilitate future study design. The aim of this work was to identify patient-valued outcome measures for headache preventive treatments among adolescents with continuous headache due to chronic migraine and their parents. METHODS: Adolescents with an International Classification of Headache Disorders, 3rd edition diagnosis of chronic migraine, who had continuous headache and who were being cared for at a tertiary pediatric headache clinic, and their parents were surveyed to query the value of treatment outcomes in the domains of headache frequency, intensity, functional impact, and associated symptoms. Individual outcomes and categories of outcomes were ranked in order of preference using weighted average rank. Results were rounded to the degree of precision with which they were measured. RESULTS: The survey was completed by 55 adolescents and 60 parents of adolescents with continuous headache due to chronic migraine. Mean age of adolescents was 16 (SD 1, range 12-17) years. Median adolescent-reported duration of continuous headache was 24 (interquartile range [IQR] 12-39) months, and adolescents had tried a median of 2 (IQR 0-5) preventive medications, only 13% of which were perceived as helpful. Overall, the most valued individual outcome measure among both adolescents and parents was a decrease in frequency of more severe headaches; however, outcomes reflecting headache intensity were most valued by adolescents, while outcomes reflecting functional impact were most valued by parents. More than 60% of adolescents felt that it was more important to measure decrease in frequency and intensity of headaches in terms of severe headaches/spikes rather than total headache days. Among associated symptoms, improvement in brain fog was most highly valued by both adolescents and parents. DISCUSSION: The results of this study provide important information about which preventive treatment outcomes are valued by adolescents with continuous headache due to chronic migraine and their parents. Results suggest that adolescents value a decrease in frequency of severe headaches over a decrease in frequency of headache days overall. Generalizability may be limited because the surveyed population was being cared for at a tertiary pediatric headache clinic and generally had headache disorders that were refractory to treatment. These results may help guide future trial design in this population with continuous headache due to chronic migraine.

OBJECTIVE: In response to concern over rising sugar-sweetened beverage (SSB) consumption, in April 2018, South Africa became the first Sub-Saharan African country to implement an SSB tax. We assess changes in pricing and acquisition of beverages from local supermarkets and small stores among 18-39 year old adults living in one township in the Western Cape, before and after tax implementation. This study is among the first evaluations of an SSB tax on the local food environment in a low-income township. DESIGN: Store beverage pricing and participant surveys were cross-sectional, analyzed 1 month before and 11 months after implementation of the tax (March 2018 and March 2019). SETTING: Langa, Western Cape, South Africa. PARTICIPANTS: Surveyed participants were residents of Langa between 18-39 years old (N=2,693 in 2018 and N=2,520 in 2019). RESULTS: Prices of taxed SSBs increased significantly among small shops and supermarkets between 2018 and 2019. There were non-significant decreases in prices of untaxed beverages in small shops, but prices of untaxed beverages increased in supermarkets. Across all store types, there was a 9 percentage point decrease in the probability of purchasing regular soda weekly pre/post-implementation. Reductions in purchasing were larger in small shops than supermarkets. CONCLUSIONS: We found some differential impacts of the levy on pricing and acquisition of beverages by retailer type in one low-income township. As other Sub-Saharan African countries consider similar fiscal policies to curb soda consumption, obesity and related diseases, this work can be used to understand the implications of these policies in the retail setting.
RESUMO
Platypuses (Ornithorhynchus anatinus) forage for macroinvertebrate prey exclusively in freshwater habitats. Because food material in their faeces is well digested and mostly unidentifiable, previous dietary studies have relied on cheek pouch assessments and stable isotope analysis. Given DNA metabarcoding can identify species composition from only fragments of genetic material, we investigated its effectiveness in analysing the diet of platypuses, and to assess variation across seasons and sexes. Of the 18 orders and 60 families identified, Ephemeroptera and Diptera were the most prevalent orders, detected in 100% of samples, followed by Trichoptera, Pulmonata, and Odonata (86.21% of samples). Caenidae and Chironomidae were the most common families. Diptera had a high average DNA read, suggesting it is an important dietary component that may have been underestimated in previous studies. We found no variation in diet between sexes and only minimal changes between seasons. DNA metabarcoding proved to be a highly useful tool for assessing platypus diet, improving prey identification compared to cheek pouch analysis, which can underestimate soft-bodied organisms, and stable isotope analysis which cannot distinguish all taxa isotopically. This will be a useful tool for investigating how platypus prey diversity is impacted by habitat degradation as a result of anthropogenic stressors.

OBJECTIVE: To review contemporary issues of health care disparities in headache medicine with regard to race/ethnicity, socioeconomic status (SES), and geography and propose solutions for addressing these disparities. METHODS: An Internet and PubMed search was performed and literature was reviewed for key concepts underpinning disparities in headache medicine. Content was refined to areas most salient to our goal of informing the provision of equitable care in headache treatment through discussions with a group of 16 experts from a range of headache subspecialties. RESULTS: Taken together, a multitude of factors, including racism, SES, insurance status, and geographical disparities, contribute to the inequities that exist within the health care system when treating headache disorders. Interventions such as improving public education, advocacy, optimizing telemedicine, engaging in community outreach to educate primary care providers, training providers in cultural sensitivity and competence and implicit bias, addressing health literacy, and developing recruitment strategies to increase representation of underserved groups within headache research are proposed as solutions to ameliorate disparities. CONCLUSION: Neurologists have a responsibility to provide and deliver equitable care to all. It is important that disparities in the management of headache disorders are identified and addressed.

Introduced predators threaten prey species worldwide, but strategies to protect vulnerable wildlife from introduced predators can be expensive, time-consuming, and logistically difficult1,2. Novel conservation strategies that reduce predation affordably and efficiently must be explored. 'Headstarting' is one such strategy, whereby prey are isolated from predators only during the critical early life stage before being returned to the wild, thus improving juvenile survivorship and recruitment to contribute to an increase in population growth3. Headstarting is a particularly useful conservation strategy for species facing higher levels of a threatening process during only the early part of their life history when mortality rates are higher, and has demonstrably improved conservation outcomes for birds and marine species3,4. Here we report findings from the first known headstarting program for a terrestrial mammal, the endangered bridled nailtail wallaby (Onychogalea fraenata) at Avocet Nature Refuge (henceforth 'Avocet') in Queensland, Australia.

PURPOSE OF REVIEW: Post-traumatic headache (PTH) consequent to mild traumatic brain injury (mTBI) is a complex, multidimensional, chronic neurological disorder. The purpose of this review is to evaluate the current neuroimaging studies on mTBI and PTH with a specific focus on brain networks and connectivity patterns. RECENT FINDINGS: We present findings on PTH incidence and prevalence, as well as the latest neuroimaging research findings on mTBI and PTH. Additionally, we propose a new strategy in studying PTH following mTBI. The diversity and heterogeneity of pathophysiological mechanisms underlying mild traumatic brain injury pose unique challenges on how we interpret neuroimaging findings in PTH. Evaluating alterations in the intrinsic brain network connectivity patterns using novel imaging and analytical techniques may provide additional insights into PTH disease state and therefore inform effective treatment strategies.

OBJECTIVE: To equip clinicians with recommendations specific to concerns related to the novel coronavirus disease 2019 (COVID-19), which impact the physical, emotional, and social health of youth with headache disorders. BACKGROUND: COVID-19 has affected societies on a global scale including children and youth with chronic headache disorders. Many concerns are predicted to arise in the 2020-2021 school year, whether classes are conducted in-person or virtually. METHODS: Clinical impressions were combined with a review of the literature, although limited due to the recent nature of this issue. RESULTS: We describe recommendations to support caregivers and youth as they face changes expected with the return to school in the fall of 2020. CONCLUSION: Although there are significant concerns for caregivers and youth with migraine given the context of changes related to the pandemic, there are many recommendations that can help minimize exacerbations of the physical, emotional, and social health of youth with chronic migraine.

OBJECTIVE: To determine whether high school start time is associated with headache frequency in adolescents with migraine. BACKGROUND: Adolescence is marked by a physiologic delayed circadian phase, characterized by later bedtimes and wake times. The American Academy of Pediatrics (AAP) recommends that high schools start no earlier than 8:30 a.m., but most high schools in the United States start earlier. The study hypothesis was that adolescents with migraine whose high schools start at 8:30 a.m. or later (late group) would have lower headache frequency than those whose schools start earlier than 8:30 a.m. (early group). METHODS: This was a cross-sectional Internet survey study of US high schoolers with migraine recruited online through social media. Comparisons were made between the late group and the early group. The primary outcome measure was self-reported headache days/month. RESULTS: In total, 1012 respondents constituted the analytic set: n = 503 in the late group versus n = 509 in the early group. Mean (SD) self-reported headache days/month was 4.8 (4.6) versus 7.7 (6.1) in the late and early groups, respectively (p < 0.001); mean difference -2.9 (95% CI -2.2 to -3.6). Mean (SD) self-reported hours of sleep on a school night was 7.9 (0.9) versus 6.9 (1.3), p < 0.001. Adjusting for total hours of sleep, sex, taking a migraine preventive, days of acute medication use, hours of homework, grade level, and missing breakfast, mean (SD) self-reported headache days/month remained lower in the late group than in the early group: 5.8 (95% CI 5.3-6.2) versus 7.1 (95% CI 6.7-7.4), (p < 0.001); mean difference -1.3 (95% CI -1.9 to -0.7). CONCLUSION: Adolescents with migraine who attend high schools that follow AAP recommendations for start times have lower self-reported headache frequency than those whose high schools start before 8:30 a.m. If prospective studies confirm this finding, shifting to a later high school start time may be an effective strategy for migraine prevention in adolescents.

Community involvement is important in good research practice. We led a community-based study to improve early detection and treatment of childhood hearing loss in rural Alaska. This study evaluated a cell phone-based hearing screening process and compared a new telemedicine specialty referral pathway to the standard primary care referral pathway. The study included community involvement, engagement, and participation from the very beginning to inform how to best design the trial. We obtained insight and feedback from community members through involvement of a core stakeholder team and through community engagement and participation in focus groups and community events. Feedback received through community involvement and participation influenced the design of the trial at key decision points. Community member guidance shaped the research question, the outcomes to be measured, and the procedures for completing the project, such as participant recruitment. This study offers an example of community involvement, engagement and participation that could be mirrored in future research to maintain the interests of participating communities. Background Effective systems for early identification and treatment of childhood hearing loss are essential in rural Alaska, where data indicate a high prevalence of childhood ear infections and hearing loss. However, loss to follow-up from school hearing screening programs is pervasive. The Hearing Norton Sound study was a mixed methods community randomized controlled trial that was developed to address this gap. The study engaged community members and participants in the design of the trial, including involvement of stakeholders as collaborators. Methods Community engagement and participation in research design occurred through focus groups and through the integration of stakeholders into the study team. Representation was cross-sectoral, involving individuals from multiple levels of the school and health system, as well as community members from each of the 15 communities. Feedback obtained between April 2017 and August 2017 informed the final design of the randomized trial, which began enrollment of children in October 2017 and concluded in March 2019. Results Stakeholder involvement and community participation shaped the design of specific trial elements (research question; comparators; outcomes and measures; telemedicine protocols; and recruitment and retention). Community involvement was strengthened by the use of multiple modalities of involvement and by the positionality of lead stakeholders on the study team. Conclusions This study highlights the effectiveness of multifaceted stakeholder involvement and participation in the design of health research conducted within Alaska Native communities. It offers an example of involvement and reporting that could be mirrored in future research in order to protect and further the interests of the participating community. Trial registration ClinicalTrials.gov, NCT03309553 , First registered 10/9/2017.
RESUMO
OBJECTIVE: To determine what dose of melatonin is most effective for treating migraine acutely in children and adolescents. BACKGROUND: Acute migraine medications may not work for all patients and may cause side effects. Melatonin is effective for migraine prevention in adults and has been used acutely for procedural pain in children. Our goal was to determine whether a "high" or "low" dose of melatonin is more effective for treating migraine acutely in youth. METHODS: In this pilot, randomized, open-label, single-center, dose-finding trial, children and adolescents aged 4-17 years with episodic migraine were randomized to "high-dose" or "low-dose" dose melatonin (<40 kg: 4 mg vs. 1 mg; ≥40 kg: 8 mg vs. 2 mg). The primary outcome measure was change in mean pain score between time 0 and 2 hours. Secondary outcomes included 2-hour pain-relief and pain-freedom rates. RESULTS: Eighty-four participants (n = 42 per group) were enrolled in this study. Mean (SD) participant age was 11.8 (3.5) years and 55% (46/84) were female. Mean (SD) headache days/month was 5.6 (3.8). Sixty-six (79%) participants provided outcome data and were included in the analyses, n = 24 in the high-dose group and n = 22 in the low-dose group. The drop-out rate was 43% (18/42) in the high-dose group vs. 48% (20/42) in the low-dose group. Mean (SD) change in pain intensity at 2 hours was -2.7 (2.1) cm in the high-dose group vs. -2.3 (2.1) cm in the low-dose group (p = .581), a difference of 0.4 cm (95% CI: -1.17 to 1.92). Two-hour pain-freedom rate was 41% (7/17) vs. 27% (4/15) in the high-dose vs. low-dose groups (p = .415), and 2-hour pain-relief rate was 94% (16/17) vs. 80% (12/15), (p = .482). There were no serious adverse events. Napping occurred in the majority (67% (14/21) high dose vs. 47% (9/19) low dose). Higher mg/kg dose of melatonin and napping were each independently associated with greater headache benefit. CONCLUSIONS: As an acute treatment for pediatric migraine, both low and high doses of melatonin were associated with pain reduction; however, study drop-out was high. Higher dose and napping after treatment predicted greater benefit.

PURPOSE: Pediatric brain cancer medulloblastoma (MB) standard-of-care results in numerous comorbidities. MB is comprised of distinct molecular subgroups. Group 3 molecular subgroup patients have the highest relapse rates and after standard-of-care have a 20% survival. Group 3 tumors have high expression of GABRA5, which codes for the α5 subunit of the γ-aminobutyric acid type A receptor (GABAAR). We are advancing a therapeutic approach for group 3 based on GABAAR modulation using benzodiazepine-derivatives. METHODS: We performed analysis of GABR and MYC expression in MB tumors and used molecular, cell biological, and whole-cell electrophysiology approaches to establish presence of a functional 'druggable' GABAAR in group 3 cells. RESULTS: Analysis of expression of 763 MB tumors reveals that group 3 tumors share high subgroup-specific and correlative expression of GABR genes, which code for GABAAR subunits α5, ß3 and γ2 and 3. There are ~ 1000 functional α5-GABAARs per group 3 patient-derived cell that mediate a basal chloride-anion efflux of 2 × 109 ions/s. Benzodiazepines, designed to prefer α5-GABAAR, impair group 3 cell viability by enhancing chloride-anion efflux with subtle changes in their structure having significant impact on potency. A potent, non-toxic benzodiazepine ('KRM-II-08') binds to the α5-GABAAR (0.8 µM EC50) enhancing a chloride-anion efflux that induces mitochondrial membrane depolarization and in response, TP53 upregulation and p53, constitutively phosphorylated at S392, cytoplasmic localization. This correlates with pro-apoptotic Bcl-2-associated death promoter protein localization. CONCLUSION: GABRA5 expression can serve as a diagnostic biomarker for group 3 tumors, while α5-GABAAR is a therapeutic target for benzodiazepine binding, enhancing an ion imbalance that induces apoptosis.
