- Abstract
Endurance events are popular worldwide and have many health benefits. However, runners and Para athletes may sustain musculoskeletal injuries or experience other health consequences from endurance events. The American Medical Society for Sports Medicine (AMSSM) Runner Health Consortium aimed to generate consensus-based survey items for use in prospective research to identify risk factors for injuries in runners and Para athletes training and competing in endurance events. The study design employed a modified Delphi approach, with a panel comprising 28 experts, including healthcare professionals, coaches, and athletes. Potential survey items were generated by panel members who subsequently engaged in three rounds of voting using Research Electronic Data Capture. Items were graded by clarity, relevance, and importance. Items achieving 80% consensus on all three aspects were retained. The response rate was 100% in R round 1 and 96% in Rrounds 2 and 3. Of 124 initial survey items, consensus was reached on 53, 34 and 22 items during Rrounds 1, 2, and 3, respectively. Two accepted items were removed due to redundancy. Combined with 10 non-voting items, 117 items covered key domains, including training and injury history, dietary behaviours and associated factors (such as menstrual function), footwear, mental health, and specific considerations for Para athletes. The consensus-based survey items should be considered by researchers to better understand the health of runners and Para athletes who train and compete in endurance sports to identify risk factors for injury., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Decisions to initiate long-term ventilation (LTV) in children with severe neurologic impairment have recently been subject to candidacy determinations by home ventilation teams that exclude patients based on their neurologic status alone. Determinations of whether decisions are inappropriate require careful analysis of specific clinical circumstances and attention to the family's values. In this Ethics Rounds, we present a case of a previously healthy child who sustained an acute severe anoxic brain injury and was assessed by the medical team to have a high likelihood of remaining minimally conscious or unconscious. It was determined that he was not a candidate for LTV based on the severity of neurologic impairment. The family disagreed and declined withdrawal of ventilatory support. Drawing upon our backgrounds in intensive care, pulmonology, and bioethics, we offer commentary on utilizing a candidacy-based approach for LTV decisions in children with severe neurologic impairment from variable perspectives, including clinical determinations of inappropriate care, ablest biases and discrimination, and obligations to maintain a just process., Competing Interests: CONFLICT OF INTEREST DISCLOSURES: The authors have indicated they have no conflicts of interest relevant to this article to disclose., (Copyright © 2024 by the American Academy of Pediatrics.)

- Abstract
We investigated the mechanism of action of an arylsulfonamide with whole-cell activity against Mycobacterium tuberculosis . We newly synthesized the molecule and confirmed it had activity against both extracellular and intracellular bacilli. The molecule had some activity against HepG2 cells but maintained some selectivity. Bacterial cytological profiling suggested that the mechanism of action was via disruption of cell wall synthesis, with similarities to an inhibitor of the mycolic acid exporter MmpL3. The compound induced expression from the IniB promoter and caused a boost in ATP production but did not induce reactive oxygen species. A mutation in MmpL3 (S591I) led to low-level resistance. Taken together, these data confirm the molecule targets cell wall biosynthesis with MmpL3 as the most probable target., Competing Interests: The authors declare no conflict of interest.

- Abstract
A modified Vesikari severity score (MVSS) is a useful research tool for assessing severity of acute gastroenteritis. We present a MVSS for studies in which a follow-up assessment of symptoms cannot be obtained. The MVSS significantly correlated with other markers of severity, including illness duration and work and school absenteeism., (Published by Oxford University Press on behalf of The Journal of the Pediatric Infectious Diseases Society 2024.)

- Abstract
Photoreception is essential for the development of the visual system, shaping vision's first synapse to cortical development. Here, we find that the lighting environment controls developmental rod apoptosis via Opn4-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs). Using genetics, sensory environment manipulations, and computational approaches, we establish a pathway where light-dependent glutamate released from ipRGCs is detected via a transiently expressed glutamate receptor (Grik3) on rod precursors within the inner retina. Communication between these cells is mediated by hybrid neurites on ipRGCs that sense light before eye opening. These structures span the ipRGC-rod precursor distance over development and contain the machinery for photoreception (Opn4) and neurotransmitter release (Vglut2 & Syp). Assessment of the human gestational retina identifies conserved hallmarks of an ipRGC-to-rod axis, including displaced rod precursors, transient GRIK3 expression, and ipRGCs with deep-projecting neurites. This analysis defines an adaptive retrograde pathway linking the sensory environment to rod precursors via ipRGCs prior to eye opening., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 Elsevier Inc.

- Abstract
The control of the respiratory rhythm and airway motor activity is essential for life. Accumulating evidence indicates that the postinspiratory complex (PiCo) is crucial for generating behaviors that occur during the postinspiratory phase, including expiratory laryngeal activity and swallowing. Located in the ventromedial medulla, PiCo is defined by neurons co-expressing two neurotransmitter markers (ChAT and Vglut2/Slc17a6). Here, we mapped the input-output connections of these neurons using viral tracers and intersectional viral-genetic tools. PiCo neurons were specifically targeted by focal injection of a doubly conditional Cre- and FlpO-dependent AAV8 viral marker (AAV8-Con/Fon-TVA-mCherry) into the left PiCo of adult Chat
Cre/wt : Vglut2FlpO/wt mice, for anterograde axonal tracing. These experiments revealed projections to various brain regions, including the Cu, nucleus of the solitary tract (NTS), Amb, X, XII, Sp5, RMg, intermediate reticular nucleus (IRt), lateral reticular nucleus (LRt), pre-Bötzinger complex (preBötC), contralateral PiCo, laterodorsal tegmental nucleus (LDTg), pedunculopontine tegmental nucleus (PPTg), periaqueductal gray matter (PAG), Kölliker-Fuse (KF), PB, and external cortex of the inferior colliculus (ECIC). A rabies virus (RV) retrograde transsynaptic approach was taken with EnvA-pseudotyped G-deleted (RV-SAD-G-GFP) to similarly target PiCo neurons in ChatCre/wt : Vglut2FlpO/wt mice, following prior injections of helper AAVs (a mixture of AAV-Ef1a-Con/Fon oG and viral vector AAV8-Con/Fon-TVA-mCherry). This combined approach revealed prominent synaptic inputs to PiCo neurons from NTS, IRt, and A1/C1. Although PiCo neurons project axons to the contralateral PiCo area, this approach did not detect direct contralateral connections. We suggest that PiCo serves as a critical integration site, projecting and receiving neuronal connections implicated in breathing, arousal, swallowing, and autonomic regulation., (© 2024 Wiley Periodicals LLC.)- Published

- Abstract
Background: Gastrointestinal (GI) complications are a significant source of morbidity for people with cystic fibrosis (PwCF). Historically, dietary recommendations in CF have focused on calories, typically emphasizing a high fat diet. The changing landscape of CF highlights the need to update this nutritional strategy. There is little research into how the quality of calories consumed by PwCF influences nutritional outcomes, GI symptoms, or likely contributors: intestinal inflammation and GI microbiology. We assessed the feasibility of a whole foods-based diet (WFD) and avoidance of ultra-processed foods, measuring safety/tolerability, adherence, and GI symptoms, as well as fecal measures of inflammation and microbiota among children with CF (CwCF) with GI symptoms., Methods: Single center, 4-week dietary intervention involving CwCF aged 5-14 years who screened positive on GI symptom questionnaire. Assessments included weight, symptom questionnaires and adverse events (AEs). Stool was analyzed for microbiota (16S rRNA) and calprotectin., Results: 108 children were pre-screened, 9 enrolled and 8 initiated and completed the study. There were no significant changes in weight and no AEs. PEDS-QL GI identified overall improvement in symptoms. Certain symptom domains (constipation, diarrhea, gas/bloating, stomach pain and hurt) demonstrated significant improvement on the WFD. Of two participants with abnormal fecal calprotectin at enrollment, both exhibited decreased values on WFD. There was no significant change in microbiota diversity., Conclusion: A WFD diet was feasible and safe in CwCF. There was improvement in GI symptom scores based on both parent and child assessments. Larger studies are needed to further investigate effects on intestinal inflammation and microbiota., Competing Interests: Conflict of interest The authors of this manuscript have no conflicts of interest to disclose., (Copyright © 2024 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

- Abstract
Rationale and Objectives: Disparities in healthcare access in the United States have been associated with race and ethnicity, as well as socioeconomic factors. Because delays in imaging may result in delayed diagnosis or clinical management, we are evaluating practices within our radiology department in hopes of decreasing disparities in access to imaging. The objective of this study is to determine the disparities in time to outpatient MRI scheduling and completion by race, ethnicity, primary language, socioeconomic status, insurance and other factors at a tertiary children's hospital., Methods: After Institutional Review Board approval, we retrospectively extracted data from all outpatient MRI exams completed at our center between 10/5/2020 and 8/31/2022. Collected data included sex, age, race/ethnicity, primary language, medical complexity, insurance type, address, need for anesthesia, ordering specialty, and order acuity. We determined times to MRI scheduling or completion using mixed effects Cox regression models and determined associations between unadjusted and fully adjusted models., Results: We analyzed 14,002 completed outpatient MRI orders from 9714 unique patients. 56.2% were White, 19.2% Hispanic, 8.4% Asian, 4.5% Black/African-American, 1.4% American Indian/Alaska Native, 0.7% Native Hawaiian/Pacific Islander, 5.7% two or more races/ethnicities, and 3.8% "Other." In fully adjusted models, there was no significant association between race/ethnicity and time to MRI scheduling and completion. In fully adjusted models, time to completion of MRI was slower among those with Medicaid (adjusted hazard ratio [95% confidence interval] of 0.92 [0.87, 0.98]), a primary language other than English (0.90 [0.82, 0.99]), non-complex chronic illness (0.72 [0.67, 0.79]), complex chronic illness (0.72 [0.67, 0.78]) and need for anesthesia (0.75 [0.71, 0.79])., Conclusion: At our tertiary children's hospital, time to completion of outpatient MRI was not associated with race, but was greater among those with Medicaid insurance, whose primary language was not English, and needing anesthesia. Advocating for faster prior authorization by Medicaid, utilizing our hospital's live interpreter phone number for scheduling, and incorporating greater child life support to decrease anesthesia use are considerations for decreasing these disparities, although surveying patients and families most impacted by these discrepancies will be important to identify the most promising interventions., Data Availability Statement: Data are not publicly available to preserve individuals' privacy due to IRB restrictions.

- Abstract
Objective: In this study, we assessed the usefulness of a previsit questionnaire for children who were referred for an initial evaluation in a mitochondrial subspecialty clinic. We explored the themes regarding parent's questions, concerns, and goals. We aimed to add to existing knowledge about the usefulness of previsit questionnaires in a pediatric specialty setting from the perspective of parents, the specialist, and the clinical coordinator. Method: We enrolled 25 patients and their parent(s) over 25 months. Questionnaires were completed by the parent(s), the clinical coordinator, and the mitochondrial specialist. Descriptive statistics and thematic analysis were used to summarize results. Results: Parental responses suggested that they are most concerned about their child's clinical problems, communication, language and developmental delays, disease progression and prognosis, understanding mitochondrial disease, quality of life, and physical challenges including muscle and energy problems. Parents felt the previsit questionnaire was very helpful for both the doctor and for themselves to be prepared for their visit. The specialist and the clinical coordinator also found it to be helpful. Parental comments suggested that they felt that writing down the story of their child's life was helpful for the provider, allowed time for reflection, and improved the appointment experience. Some felt it was a difficult or redundant activity. Conclusion: Parents were often pleased to complete the previsit questionnaire. This allowed them to highlight concerns and share information that they wanted the care team to know about their child. We revised the tool based on feedback from parents and the specialist and will continue to use it in our clinic., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Juvenile idiopathic arthritis (JIA) is common in pediatric rheumatology. Despite treatment, many patients experience persistent disease activity. Joint hypermobility (JH), defined by an excessive range of motion across multiple joints, is prevalent in children and adolescents and may influence disease outcomes in JIA., Objective: This study examines the impact of JH on symptoms in youth and young adults with JIA., Methods: Data were obtained from the PR-COIN network and included patients under 21 years old with a diagnosis of JIA. Patients with JIA and JH were matched with those having JIA-only based on age, sex assigned at birth, JIA subtype, and medication exposure. Clinical data, including disease activity measures, patient well-being, and pain ratings, were collected at baseline and follow-up visits., Results: The sample included 420 patients with JIA + JH and 2100 with JIA only. The JIA + JH group exhibited higher disease activity at baseline, more active arthritis joints, elevated physician global assessment of disease activity scores, and worse patient-reported well-being. These differences persisted over time. The JIA + JH group had a 19-20% greater likelihood of maintaining high disease activity scores and worsening over subsequent visits, indicating a significant impact of JH on disease progression., Conclusion: JH in youth with JIA is associated with higher and persistent disease activity, suggesting that JH significantly contributes to the disease burden in patients with JIA and should be considered in treatment strategies. Future research should further explore the mechanisms by which JH influences disease activity and investigate comprehensive management approaches to improve outcomes for this population. Key Points • Children with JIA and joint hypermobility (JH) exhibit significantly higher disease activity at baseline compared to those with JIA only, including more active arthritis joints and elevated physician global assessment scores. • The presence of JH in JIA patients is associated with poorer patient-reported well-being and higher overall disease activity scores, which persist over time despite treatment. • JIA + JH patients have a 19-20% greater likelihood of maintaining high disease activity and worsening over subsequent visits, indicating a significant impact of JH on disease progression. • The study suggests that JH should be considered an important clinical factor in the management of JIA, with targeted interventions needed to address the increased disease activity and improve overall patient outcomes., (© 2024.

- Abstract
Background: Newborn screening (NBS) for cystic fibrosis (CF) is universal in the United States. Protocols vary but include an immunoreactive trypsinogen (IRT) level and CFTR variant panel. California CF NBS has a 3-step screening: IRT level, variant panel, and CFTR sequencing if only one variant identified on panel., Methods: This was a cohort study of infants with CF born in California (2007-2021) to examine racial and ethnic differences in having a false-negative NBS result for CF and at which step the false-negative occurred. We examined how different CFTR variant panels would improve detection of variants by race and ethnicity: original 39-variant panel, current 75-variant panel, and all 402 disease-causing CFTR variants in the CFTR2 database., Results: Of the 912 infants born in California with CF, 84 had a false-negative result: 38 due to low IRT level and 46 with a high IRT value (but incomplete variant detection). Asian (OR 6.3) and Black infants (OR 2.5) were more likely to have a false-negative screening result than non-Hispanic white infants. The majority of false-negative screening (but CF diagnosis) cases among American Indian/Native Alaskan and non-Hispanic White infants were due to low IRT levels. The majority of Asian and Hispanic infants with false-negative screening had no variants detected. Detection of two CFTR variants was improved with the 75-variant panel in Black, Hispanic, and non-Hispanic White infants and with the 402-variant panel in Black, Hispanic, non-Hispanic White, and other race infants., Conclusions: Larger CFTR panels in NBS improved the detection of CF in all races and ethnicities., (© 2024 Wiley Periodicals LLC.)

Abstract: During adolescence major shifts in sleep and circadian systems occur with a notable circadian phase delay. Yet, the circadian influence on pain during early adolescence is largely unknown. Using 2 years of data from the Adolescent Brain Cognitive Development study, we investigated the impact of chronotype on pain incidence, moderate-to-severe pain, and multiregion pain 1 year later in U.S. adolescents. Based on the Munich ChronoType Questionnaire, chronotype was calculated as the midpoint between sleep onset and offset on free days, corrected for sleep debt over the week. Adolescents reported pain presence over the past month, and if present, rated pain intensity (0-10 numerical rating scale; ≥ 4 defined as moderate-to-severe pain) and body site locations (Collaborative Health Outcomes Information Registry Body Map; ≥2 regions defined as multiregion pain). Three-level random intercept logistic regression models were specified for each pain outcome, adjusting for baseline sociodemographic and developmental characteristics. Among 5991 initially pain-free adolescents (mean age 12.0 years, SD 0.7), the mean chronotype was 3:59 am (SD 97 minutes), and the 1-year incidence of pain, moderate-to-severe pain, and multiregion pain was 24.4%, 15.2%, and 13.5%, respectively. Each hour later chronotype at baseline was associated with higher odds of developing any pain (odds ratio [OR] = 1.06, 95% confidence interval [CI] = 1.01, 1.11), moderate-to-severe pain (OR = 1.10, 95% CI = 1.05-1.17), and multiregion pain (OR = 1.08, 95% CI = 1.02-1.14) during 1-year follow-up. In this diverse U.S. adolescent sample, later chronotype predicted higher incidence of new-onset pain., (Copyright © 2024 International Association for the Study of Pain.)

- Abstract
The purpose of this study is to gain insights into potential genetic factors contributing to the infant's vulnerability to Sudden Unexpected Infant Death (SUID). Whole Genome Sequencing (WGS) was performed on 144 infants that succumbed to SUID, and 573 healthy adults. Variants were filtered by gnomAD allele frequencies and predictions of functional consequences. Variants of interest were identified in 88 genes, in 64.6% of our cohort. Seventy-three of these have been previously associated with SIDS/SUID/SUDP. Forty-three can be characterized as cardiac genes and are related to cardiomyopathies, arrhythmias, and other conditions. Variants in 22 genes were associated with neurologic functions. Variants were also found in 13 genes reported to be pathogenic for various systemic disorders and in two genes associated with immunological function. Variants in eight genes are implicated in the response to hypoxia and the regulation of reactive oxygen species (ROS) and have not been previously described in SIDS/SUID/SUDP. Seventy-two infants met the triple risk hypothesis criteria. Our study confirms and further expands the list of genetic variants associated with SUID. The abundance of genes associated with heart disease and the discovery of variants associated with the redox metabolism have important mechanistic implications for the pathophysiology of SUID., (© 2024 The Authors.

- Abstract
Background and Aims: It is not known why severe cystic fibrosis (CF) liver disease (CFLD) with portal hypertension occurs in only ~7% of people with CF. We aimed to identify genetic modifiers for severe CFLD to improve understanding of disease mechanisms., Approach and Results: Whole-genome sequencing was available in 4082 people with CF with pancreatic insufficiency (n = 516 with severe CFLD; n = 3566 without CFLD). We tested ~15.9 million single nucleotide polymorphisms (SNPs) for association with severe CFLD versus no-CFLD, using pre-modulator clinical phenotypes including (1) genetic variant ( SERPINA1 ; Z allele) previously associated with severe CFLD; (2) candidate SNPs (n = 205) associated with non-CF liver diseases; (3) genome-wide association study of common/rare SNPs; (4) transcriptome-wide association; and (5) gene-level and pathway analyses. The Z allele was significantly associated with severe CFLD ( p = 1.1 × 10 -4 ). No significant candidate SNPs were identified. A genome-wide association study identified genome-wide significant SNPs in 2 loci and 2 suggestive loci. These 4 loci contained genes [significant, PKD1 ( p = 8.05 × 10 -10 ) and FNBP1 ( p = 4.74 × 10 -9 ); suggestive, DUSP6 ( p = 1.51 × 10 -7 ) and ANKUB1 ( p = 4.69 × 10 -7 )] relevant to severe CFLD pathophysiology. The transcriptome-wide association identified 3 genes [ CXCR1 ( p = 1.01 × 10 -6 ) , AAMP ( p = 1.07 × 10 -6 ), and TRBV24 ( p = 1.23 × 10 -5 )] involved in hepatic inflammation and innate immunity. Gene-ranked analyses identified pathways enriched in genes linked to multiple liver pathologies., Conclusion: These results identify loci/genes associated with severe CFLD that point to disease mechanisms involving hepatic fibrosis, inflammation, innate immune function, vascular pathology, intracellular signaling, actin cytoskeleton and tight junction integrity and mechanisms of hepatic steatosis and insulin resistance. These discoveries will facilitate mechanistic studies and the development of therapeutics for severe CFLD., (Copyright © 2024 American Association for the Study of Liver Diseases.)

- Abstract
Different parents grieve differently. However, research directed at understanding the important contextual or individual factors that influence the path each bereaved parent takes is lacking. In this qualitative analysis we seek to understand the array of bereaved parent experiences more completely. By deeply diving into one parent dyad using interpretive phenomenology analysis and situating that story within the conventional content analysis of 13 other bereaved parents of adolescents and young adults (AYAs) who died from advanced cancer, we illustrate the roles of religion/spirituality, maintaining a connection, and fulfilling parental roles as elements of grief processing. Clinicians and investigators should consider similar individualized approaches to understanding and supporting the grief experiences of bereaved parents before and after the death of a child., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Purpose: As population-based screening programs to identify genetic conditions in adults using genomic sequencing (GS) are increasingly available, validated patient-centered outcome measures are needed to understand participants' experience. We aimed to develop and validate an instrument to assess the perceived utility of GS in the context of adult screening., Methods: Informed by a 5-domain conceptual model, we used a 5-step approach to instrument development and validation: (1) item writing, (2) cognitive testing, (3) pilot testing and item reduction, (4) psychometric testing, and (5) evaluation of construct validity. Adults undergoing risk-based or population-based GS who had received GS results as part of ongoing research studies participated in structured cognitive interviews and 2 rounds of surveys. After item pool refinement, we conducted an exploratory factor analysis and calculated Pearson correlations with related instruments., Results: We derived the 18-item Adult Screening version of the GENEtic Utility scale (total sum score α = .87). Mirroring the Pediatric Diagnostic version, the instrument has a 2-factor structure, including an Informational Utility subscale (14 items, α = .89) and an Emotional Utility subscale (4 items, α = .75). The Informational Utility subscale was strongly associated with empowerment and personal utility of GS. Correlations of the Emotional Utility subscale with psychosocial impact and anxiety and depression were weak to moderate., Conclusion: Initial psychometric testing of the Adult Screening GENEtic Utility scale demonstrates its promise, and additional validation in translational genomics research is warranted., Competing Interests: Conflict of Interest Dr Smith’s work has been funded by the NIH.

- Abstract
Context: Limited data exists about care received by children with complex chronic conditions (CCCs) in the final years of their disease and end-of-life (EOL)., Objective: To examine hospital performance on EOL quality measures and to describe healthcare services during the last two years of life for children with CCCs who died in-hospital., Methods: Retrospective automated electronic health record review of children with ≥1 CCC ICD-10 diagnosis code, who died inpatient between October 2020 and March 2023 at a single quaternary U.S. children's hospital. Quality was assessed based on performance on 15 measures across five domains: healthcare utilization, interprofessional supports, medical intensity, symptom management, and communication. Quality EOL care and healthcare services in the last two years of life were determined overall by age group and per patient. Descriptive statistics were used to evaluate demographic differences by age., Results: 266 children with CCCs died in the study timeframe; 45% were infants (n = 120), 52% (n = 137) were male, 42% (n = 113) were white, 64% (n = 170) were non-Hispanic, and 59% (n=156) had public insurance. Children had a median of three CCCs (IQR 2.4; range 1-8). On average, children met 69% (SD 13%) of EOL quality measures for which they were eligible. In the two years prior to death, 98% (n = 261) had an ICU admission, 75% (n = 200) had a procedure requiring sedation, and 29% (n = 79) had received cardiopulmonary resuscitation. 86% (n = 229) died in the ICU., Conclusion: In this study, children with CCCs met 69% of quality measures and received high-intensity healthcare in the last two years of life., (Copyright © 2024 American Academy of Hospice and Palliative Medicine.

- Abstract
Lay Abstract: Previous research has shown that girls/women are diagnosed later than boys/men with autism. Individuals who are diagnosed later in life, especially girls/women, have greater anxious and depressive symptoms. Previous research has been limited due to narrow inclusionary criteria for enrollment in studies. The present study uses two samples-one clinic-based, large "real-world" sample and another research-based sample with strict criteria for autism diagnosis-to understand the relationships between diagnostic age, sex assigned at birth, and symptoms of anxiety/depression. In both samples, those who were diagnosed later had greater anxious/depressive symptoms, and anxiety was not predicted by sex. In the clinic-based but not research-based sample, those assigned female at birth were diagnosed later than those assigned male at birth. In the clinic-based sample only, individuals assigned female at birth and who were later diagnosed experienced greater symptoms of anxiety/depression compared to those assigned male who benefited from earlier diagnostic timing. Within the research-based sample, those assigned female at birth had greater depressive symptoms than those assigned male. These findings highlight the importance of timely identification of autism, especially for girls/women who are often diagnosed later. Community-based samples are needed to better understand real-world sex-based and diagnostic age-based disparities in mental health., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Social determinants of health shape a child's transplant course. We describe the association between neighborhood socioeconomic deprivation, transplant characteristics, and graft survival in US pediatric kidney transplant recipients., Methods: US recipients <18 years of age at listing transplanted January 1st, 2010, to May 31st, 2022 (N=9,178) were included from the Scientific Registry of Transplant Recipients. Recipients were stratified into three groups according to Material Community Deprivation Index score, with greater score representing higher neighborhood socioeconomic deprivation. Outcomes were modeled using multivariable logistic regression and Cox proportional hazards models., Results: Twenty-four percent (N=110) of recipients from neighborhoods of high socioeconomic deprivation identified as being of Black race, versus 12% (N=383) of recipients from neighborhoods of low socioeconomic deprivation. Neighborhoods of high socioeconomic deprivation had a much greater proportion of recipients identifying as being of Hispanic ethnicity (67%, N=311), versus neighborhoods of low socioeconomic deprivation (17%, N=562). The hazard of graft loss was 55% higher (aHR 1.55, 95% CI: 1.24, 1.94) for recipients from neighborhoods of high versus recipients from low socioeconomic deprivation neighborhoods when adjusted for base covariates, race and ethnicity, and insurance status, with 59% lower odds (aOR 0.41, 95% CI: 0.30, 0.56) of living donor transplantation and, although not statistically significant, 8% lower odds (aOR 0.92, 95% CI: 0.72, 1.19) of preemptive transplantation. The hazard of graft loss was 41% higher (aHR 1.41, 95% CI: 1.25, 1.60) for recipients from neighborhoods of intermediate versus recipients from low socioeconomic deprivation neighborhoods when adjusted for base covariates, race and ethnicity, and insurance status, with 27% lower odds (aOR 0.73, 95% CI: 0.66, 0.81) of living donor transplantation and 11% lower odds (aOR 0.89, 95% CI: 0.80, 0.99) of preemptive transplantation., Conclusions: Children from neighborhoods of high socioeconomic deprivation have worse graft survival and lower utilization of preemptive and living donor transplantation. These findings demonstrate inequities in pediatric kidney transplantation that warrant further intervention., (Copyright © 2024 by the American Society of Nephrology.)

- Abstract
Background: The COVID-19 pandemic raised unprecedented challenges to vaccinating children. This multi-center study aimed to compare on-time vaccination of children before and during the COVID-19 pandemic and identify key factors associated with on-time vaccination., Methods: This study was conducted among children aged 0-6 years enrolled in the New Vaccine Surveillance Network at seven geographically diverse U.S. academic medical centers. Children with acute respiratory illness or acute gastroenteritis were enrolled from emergency department and inpatient settings; healthy control subjects were enrolled from primary care practices. Vaccination data were collected and verified from patient medical records, immunization information systems, and/or provider documentation. On-time vaccination according to Advisory Committee on Immunization Practices recommendations was compared between pre-pandemic (December 2018-February 2020) and pandemic (March 2020-August 2021) periods using bivariate and multivariable analyses, adjusting for key demographic, clinical, and study characteristics., Results: A total of 24,713 children were included in the analytic sample (non-Hispanic 73.4 %; White 51.0 %; publicly insured 69.0 %). On-time vaccination declined between the pre-pandemic (67.3 %) and pandemic (65.4 %) periods (Adjusted Odds Ratio 0.89, 95 % CI 0.84-0.95). The largest declines were observed among children who were < 12 months, male, Black, publicly insured, or whose mothers had a high school-equivalent education or less. The pandemic impact also varied by vaccine type and study site., Conclusions: This multi-center study revealed a relatively modest overall reduction in on-time vaccination, which may reflect multilevel efforts to address pandemic-associated challenges. However, some patient subgroups and sites experienced greater reductions in on-time vaccination, highlighting the importance of tailoring interventions to increase equitable vaccine delivery, access, and acceptance across populations and communities., Competing Interests: Declaration of competing interest N.B.H.: Research funding from Sanofi, Quidel, and Merck.

27. A Mixed Electrical and Chemical Synapse in the Thalamic Reticular Nucleus.

Landisman CE and Coulon P
- Abstract
The thalamic reticular nucleus (TRN) plays a major role in modulating the transfer of information from the thalamus to the cortex. GABAergic inhibition by the TRN is potentially synchronized by electrical synapses between TRN neurons, and TRN neurons are also sparsely connected to each other via chemical synapses. Paired recordings have shown that electrical coupling is abundant between TRN neurons, especially amongst those within close proximity, but no combined electrical and chemical coupling has been directly demonstrated in rats. Here, we report on a single pair of TRN neurons that were coupled both electrically and chemically. This is the only such example that we have found in hundreds of paired recordings of closely apposed neurons within the TRN.

- Abstract
Neonatal hypoxia (Hx) causes white matter (WM) injury, particularly in the cerebellum. We previously demonstrated Hx-induced reduction of cerebellar Purkinje cell (PC) activity results in locomotor deficits. Yet, the mechanism of Hx-induced cerebellar WM injury and associated locomotor abnormalities remains undetermined. Here, we show that the cerebellar WM injury and linked locomotor deficits are driven by PC activity and are reversed when PC activity is restored. Using optogenetics and multielectrode array recordings, we manipulated PC activity and captured the resulting cellular responses in WM oligodendrocyte precursor cells and GABAergic interneurons. To emulate the effects of Hx, we used light activated Halorhodopsin targeted specifically to the PC layer of normal mice. Suppression of PC firing activity at P13 and P21 phenocopied the locomotor deficits observed in Hx. Moreover, histopathologic analysis of the developing cerebellar WM following PC inhibition (P21) revealed a corresponding reduction in oligodendrocyte maturation and myelination, akin to our findings in Hx mice. Conversely, PC stimulation restored PC activity, promoted oligodendrocyte maturation and enhanced myelination, resulting in reversed Hx-induced locomotor deficits. Our findings highlight the crucial role of PC activity in cerebellar WM development and locomotor performance following neonatal injury. Significance statement Adult survivors of prematurity often experience locomotor incoordination secondary to cerebellar dysfunction. The cerebellum develops in the last trimester of pregnancy, a period that preterm neonates miss. Here, we show how neonatal hypoxia alters the crosstalk between neurons and oligodendrocytes in the developing cerebellum. Through loss-of-function and gain-of-function experiments, we unveiled that neuronal activity drives cerebellum-associated white matter injury and locomotor dysfunction after hypoxia. Importantly, restoring neuronal activity using direct neurophysiological stimulation reversed the hypoxia-induced white matter injury and locomotor deficits. Early cerebellar neuronal stimulation could serve as a potential therapeutic intervention for locomotor dysfunction in neonates., (Copyright © 2024 the authors.)

- Abstract
Chromosomal translocations involving the mixed-lineage leukemia (MLL) locus generate potent oncogenic fusion proteins (oncoproteins) that disrupt regulation of developmental gene expression. By profiling the oncoprotein-target sites of 36 broadly representative MLL-rearranged leukemia samples, including three samples that underwent a lymphoid-to-myeloid lineage-switching event in response to therapy, we find the genomic enrichment of the oncoprotein is highly variable between samples and subject to dynamic regulation. At high levels of expression, the oncoproteins preferentially activate either an acute lymphoblastic leukemia (ALL) program, enriched for pro-B-cell genes, or an acute myeloid leukemia (AML) program, enriched for hematopoietic-stem-cell genes. The fusion-partner-specific-binding patterns over these gene sets are highly correlated with the prevalence of each mutation in ALL versus AML. In lineage-switching samples the oncoprotein levels are reduced and the oncoproteins preferentially activate granulocyte-monocyte progenitor (GMP) genes. In a sample that lineage switched during treatment with the menin inhibitor revumenib, the oncoprotein and menin are reduced to undetectable levels, but ENL, a transcriptional cofactor of the oncoprotein, persists on numerous oncoprotein-target loci, including genes in the GMP-like lineage-switching program. We propose MLL oncoproteins promote lineage-switching events through dynamic chromatin binding at lineage-specific target genes, and may support resistance to menin inhibitors through similar changes in chromatin occupancy., (© 2024.

- Abstract
Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease, characterized by progressive destruction of small intrahepatic bile ducts and portal inflammation. Treatment options are limited, with reliance on liver transplantation in advanced cases. The adaptive immune response is implicated in disease pathogenesis by the presence of anti-mitochondrial antibodies targeting the E2 subunit of the pyruvate dehydrogenase complex (PDC-E2) in 90-95 % of patients and T cells infiltrating the portal tracts. Here, we examined T cell responses to peptides derived from PDC-E2, with a focus on CD4 T cell responses restricted to HLA Class II DRB4∗01:01, an allele found in 62 % of PBC patients, to uncover PDC-E2 epitopes that could be used for engineered regulatory T cell (Treg; EngTreg) therapy. Using an activation-induced marker assay and single cell RNA-sequencing, we found clonal expansion of CD4 T cells reactive to PDC-E2 epitopes among both T conventional (Tconv) and Tregs. Those T cell receptor (TCR) repertoires were non-overlapping and private and included TCRs specific for a novel PDC-E2 epitope restricted to DRB4∗01:01. CD4 Tconv cells reactive to the PDC-E2 novel epitope showed phenotypic heterogeneity skewed towards T follicular helper cells. Using a TCR specific for this novel PDC-E2 epitope, we created an EngTreg that suppressed PDC-E2-specific polyclonal CD4 Tconv cells from PBC patients. This study advances knowledge of PDC-E2-specific T cell responses and introduces a novel PDC-E2 epitope recognized by both Tconv and Tregs. Generation of EngTreg specific for this epitope provides therapeutic potential for PBC., Competing Interests: Declaration of competing interests JHB is a scientific co-founder and Scientific Advisory Board member of GentiBio, consultant for Bristol Myers Squibb and Hotspot Therapeutics, and has past and current research projects sponsored by GentiBio, Amgen, Bristol Myers Squibb, Janssen, Novo Nordisk, and Pfizer.

- Abstract
Nontuberculous mycobacteria (NTM) are emerging human pathogens linked to severe pulmonary diseases. Current treatments involve the prolonged use of multiple drugs and are often ineffective. Bacterial dihydrofolate reductase (DHFR) is a key enzyme targeted by antibiotics in Gram-negative bacterial infections. However, existing DHFR inhibitors designed for Gram-negative bacteria often fail against mycobacterial DHFRs. Here, we detail the rational design of NTM DHFR inhibitors based on P218 , a malarial DHFR inhibitor. We identified compound 8 , a 2,4-diaminopyrimidine exhibiting improved pharmacological properties and activity against purified DHFR, and whole cell cultures of two predominant NTM species: Mycobacterium avium and Mycobacterium abscessus . This study underscores the potential of compound 8 as a promising candidate for the in vivo validation of DHFR as an effective treatment against NTM infections.

- Abstract
Objective: To describe the adaptation and feasibility of the Swedish version of the Promoting Resilience in Stress Management (PRISM) intervention among adolescents and young adults (AYAs) newly diagnosed with cancer., Methods: PRISM is a 5-session, manualized program designed to strengthen AYAs individual resources for managing stress by promoting resilience skills: stress-management, goal-setting, cognitive reframing and meaning-making. It is delivered 1:1 by an interventionist via video-visits. PRISM was developed in the US and adapted for a Swedish population. A feasibility study was conducted looking at recruitment, retention, acceptability of the intervention (evaluation survey and exit interviews) and pre- and post- exploratory psychosocial outcome measures (resilience, global health, emotional functioning and rehabilitation needs). Participants were recruited from a comprehensive cancer center in Sweden., Results: Of the 31 eligible individuals (16-30 years), 20 (65%) agreed to participate and 11 (55%) completed PRISM. Eighty-six percent (6/7) of the participants who completed the evaluation survey thought that the order of the modules and the content were "very good or good". The AYAs that participated in the exit interviews expressed that the programme contributed new knowledge and for some confirmed previous knowledge, which was valuable both during and after participation. The role of the interventionist was stressed as important to support participants through the programme. Suggestions for the future included making PRISM more personalized. Exploratory quantitative analyses suggested improved mean scores regarding resilience, global health and emotional functioning from pre- to post-intervention., Conclusions: This study suggests that participating in PRISM has the potential to guide AYAs during the initial period after a cancer diagnosis. Further work to make PRISM more personalized might increase AYAs' interest in, and completion of, PRISM.

- Abstract
Unknown factors regulate mitochondrial U-insertion/deletion (U-indel) RNA editing in procyclic-form (PCF) and bloodstream-form (BSF) T. brucei. This editing, directed by anti-sense gRNAs, creates canonical protein-encoding mRNAs and may developmentally control respiration. Canonical editing by gRNAs that specify protein-encoding mRNA sequences occurs amid massive non-canonical editing of unclear sources and biological significance. We found PCF-specific repression at a major early checkpoint in mRNA ND7, involving helicase KREH2-dependent opposite modulation of canonical and non-canonical 'terminator' gRNA utilization. Terminator-programmed editing derails canonical editing and installs proposed repressive structure in 30% of the ND7 transcriptome. BSF-to-PCF differentiation in vitro recreated this negative control. Remarkably, KREH2-RNAi knockdown relieved repression and increased editing progression by reverting canonical/terminator gRNA utilization. ND7 transcripts lacking early terminator-directed editing in PCF exhibited similar negative editing control along the mRNA sequence, suggesting global modulation of gRNA utilization fidelity. The terminator is a 'moonlighting' gRNA also associated with mRNA COX3 canonical editing, so the gRNA transcriptome seems multifunctional. Thus, KREH2 is the first identified repressor in developmental editing control. This and our prior work support a model whereby KREH2 activates or represses editing in a stage and substrate-specific manner. KREH2's novel dual role tunes mitochondrial gene expression in either direction during development., (© The Author(s) 2024. Published by Oxford University Press on behalf of Nucleic Acids Research.)

- Abstract
Background: Pregnant women are significantly underrepresented in clinical trials, yet most of them take medication during pregnancy despite the limited safety data. The objective of this study was to characterize medication use during pregnancy and apply propensity score matching method at scale on patient records to accelerate and prioritize the drug effect signal detection associated with the risk of preterm birth and other adverse pregnancy outcomes., Methods: This was a retrospective study on continuously enrolled women who delivered live births between 2013/01/01 and 2022/12/31 (n = 365,075) at Providence St. Joseph Health. Our exposures of interest were all outpatient medications prescribed during pregnancy. We limited our analyses to medication that met the minimal sample size (n = 600). The primary outcome of interest was preterm birth. Secondary outcomes of interest were small for gestational age and low birth weight. We used propensity score matching at scale to evaluate the risk of these adverse pregnancy outcomes associated with drug exposure after adjusting for demographics, pregnancy characteristics, and comorbidities., Results: The total medication prescription rate increased from 58.5 to 75.3% (P < 0.0001) from 2013 to 2022. The prevalence rate of preterm birth was 7.7%. One hundred seventy-five out of 1329 prenatally prescribed outpatient medications met the minimum sample size. We identified 58 medications statistically significantly associated with the risk of preterm birth (P ≤ 0.1; decreased: 12, increased: 46)., Conclusions: Most pregnant women are prescribed medication during pregnancy. This highlights the need to utilize existing real-world data to enhance our knowledge of the safety of medications in pregnancy. We narrowed down from 1329 to 58 medications that showed statistically significant association with the risk of preterm birth even after addressing numerous covariates through propensity score matching. This data-driven approach demonstrated that multiple testable hypotheses in pregnancy pharmacology can be prioritized at scale and lays the foundation for application in other pregnancy outcomes., (© 2024.

- Abstract
Malaria, caused by Plasmodium parasites, imposes a significant health burden and live-attenuated parasites are being pursued as vaccines. Here, we report on the creation of a genetically attenuated parasite by the deletion of Plasmodium LINUP, encoding a liver stage nuclear protein. In the rodent parasite Plasmodium yoelii, LINUP expression was restricted to liver stage nuclei after the onset of liver stage schizogony. Compared to wildtype P. yoelii, P. yoelii LINUP gene deletion parasites (linup
- ) exhibited no phenotype in blood stages and mosquito stages but suffered developmental arrest late in liver stage schizogony with a pronounced defect in exo-erythrocytic merozoite formation. This defect caused severe attenuation of the liver stage-to-blood stage transition and immunization of mice with linup- parasites conferred robust protection against infectious sporozoite challenge. LINUP gene deletion in the human parasite Plasmodium falciparum also caused a severe defect in late liver stage differentiation. Importantly, P. falciparum linup- liver stages completely failed to transition from the liver stage to a viable blood stage infection in a humanized mouse model. These results suggest that P. falciparum LINUP is an ideal target for late liver stage attenuation that can be incorporated into a late liver stage-arresting replication competent whole parasite vaccine., (© 2024.

- Abstract
An increasing number of individuals with intellectual developmental disorder (IDD) and heterozygous variants in BCL11A are identified, yet our knowledge of manifestations and mutational spectrum is lacking. To address this, we performed detailed analysis of 42 individuals with BCL11A-related IDD (BCL11A-IDD, a.k.a. Dias-Logan syndrome) ascertained through an international collaborative network, and reviewed 35 additional previously reported patients. Analysis of 77 affected individuals identified 60 unique disease-causing variants (30 frameshift, 7 missense, 6 splice-site, 17 stop-gain) and 8 unique BCL11A microdeletions. We define the most prevalent features of BCL11A-IDD: IDD, postnatal-onset microcephaly, hypotonia, behavioral abnormalities, autism spectrum disorder, and persistence of fetal hemoglobin (HbF), and identify autonomic dysregulation as new feature. BCL11A-IDD is distinguished from 2p16 microdeletion syndrome, which has a higher incidence of congenital anomalies. Our results underscore BCL11A as an important transcription factor in human hindbrain development, identifying a previously underrecognized phenotype of a small brainstem with a reduced pons/medulla ratio. Genotype-phenotype correlation revealed an isoform-dependent trend in severity of truncating variants: those affecting all isoforms are associated with higher frequency of hypotonia, and those affecting the long (BCL11A-L) and extra-long (-XL) isoforms, sparing the short (-S), are associated with higher frequency of postnatal microcephaly. With the largest international cohort to date, this study highlights persistence of fetal hemoglobin as a consistent biomarker and hindbrain abnormalities as a common feature. It contributes significantly to our understanding of BCL11A-IDD through an extensive unbiased multi-center assessment, providing valuable insights for diagnosis, management and counselling, and into BCL11A's role in brain development., (© 2024.

37. Uncovering the Embryonic Origins of Duchenne Muscular Dystrophy.

Barrett P, Louie KW, Dupont JB, Mack DL, and Maves L
- Abstract
Duchenne muscular dystrophy (DMD) is a severe degenerative muscle disease caused by mutations in the DMD gene, which encodes dystrophin. Despite its initial description in the late 19th century by French neurologist Guillaume Duchenne de Boulogne, and identification of causal DMD genetic mutations in the 1980s, therapeutics remain challenging. The current standard of care is corticosteroid treatment, which delays the progression of muscle dysfunction but is associated with significant adverse effects. Emerging therapeutic approaches, including AAV-mediated gene transfer, CRISPR gene editing, and small molecule interventions, are under development but face considerable obstacles. Although DMD is viewed as a progressive muscle disease, muscle damage and abnormal molecular signatures are already evident during fetal myogenesis. This early onset of pathology suggests that the limited success of current therapies may partly be due to their administration after aberrant embryonic myogenesis has occurred in the absence of dystrophin. Consequently, identifying optimal therapeutic strategies and intervention windows for DMD may depend on a better understanding of the earliest DMD disease mechanisms. As newer techniques are applied, the field is gaining increasingly detailed insights into the early muscle developmental abnormalities in DMD. A comprehensive understanding of the initial events in DMD pathogenesis and progression will facilitate the generation and testing of effective therapeutic interventions., (© 2024 Wiley Periodicals LLC.)

- Abstract
Painimation, a novel digital pain assessment tool, allows patients to communicate their pain quality, intensity, and location using abstract animations and a paintable body image. This study determined the construct validity of pain animations and body image measures by testing correlations with validated pain outcomes in adults with sickle cell disease (SCD). Analyses used baseline data from a multisite randomized trial of 359 adults with SCD and chronic pain. Participants completed questionnaires on demographics, pain severity, frequency and interference, catastrophizing, opioid use, mood and quality of life, plus the Painimation app. Participants were categorized by selected pain animations, and were split into groups based on the proportion of painted body image. The "shooting" pain animation and greater body image scores associated with poorer pain outcomes in univariate analyses, except "happy" mood days. Potential confounding was evaluated by age, gender, race, education, disability, site, depression, and anxiety. Only depression scores significantly covaried in multivariate models, accounting for the effect of greater body image score and shooting animation on all outcomes except daily pain intensity. Both pain animations and body image measures correlated with validated pain outcomes, quality of life and mental health measures. This demonstrates animations and body image data can assess SCD pain severity, potentially with more accuracy than a 0-10 scale. In exploratory analyses, depression scores accounted for the association between Painimation and other pain outcomes. Future research will explore whether Painimation can differentiate biological and psychosocial pain components. PERSPECTIVE: This article presents the preliminary construct validity of Painimation in sickle cell disease (SCD) by examining the associations of "pain animations" and body area image data with daily e-diary and traditional self-report pain outcomes., (Copyright © 2024.

- Abstract
Newborn genomic sequencing (NBSeq) has the potential to substantially improve early detection of rare genetic conditions, allowing for pre-symptomatic treatment to optimize outcomes. Expanding conceptions of the clinical utility of NBSeq include earlier access to behavioral early intervention to support the acquisition of core motor, cognitive, communication, and adaptive skills during critical windows in early development. However, important questions remain about equitable access to early intervention programs for the growing number of infants identified with a genetic condition via NBSeq. We review the current NBSeq public health, clinical, and research landscape, and highlight ongoing international research efforts to collect population-level data on the utility of NBSeq for healthy newborns. We then explore the challenges facing a specific Early Intervention (EI) system-the US federally supported "Part C" system-for meeting the developmental needs of young children with genetic diagnoses, including structural limitations related to funding, variable eligibility criteria, and lack of collaboration with newborn screening programs. We conclude with a set of questions to guide future research at the intersection of NBSeq, newborn screening, and EI, which once answered, can steer future policy to ensure that EI service systems can optimally support the developmental needs of infants impacted by broader implementation of NBSeq. IMPACT: Existing literature on the clinical benefits of genome sequencing in newborns tends to focus on earlier provision of medical interventions, with less attention to the ongoing developmental needs of very young children with genetic conditions. This review outlines the developmental needs of a growing number of children diagnosed with genetic conditions in infancy and describes the strengths and limitations of the United States Early Intervention system (IDEA Part C) for meeting those needs., (© 2024.

- Abstract
HIV exposed but uninfected infants (iHEU) display altered immunity and are at increased risk of infection. We previously reported that iHEU have decreased maternal microchimerism (MMc)-maternal cells transferred to the offspring in utero/during breastfeeding. We quantified MMc in T cell subpopulations in iHEU and unexposed infants (iHU) to determine whether a selective deficiency in MMc contributes to altered cellular immunity. Across all infants, MMc levels were highest in CD8+ T cells; however, the level of CD8+ T cell MMc was lower in iHEU versus iHU. In limited functional studies, we did not identify CMV-specific MMc during infant primary infection., (© The Author(s) 2024.

- Abstract
Population-level efforts are needed to increase levels of physical activity and healthy eating to reduce and manage chronic diseases such as obesity, cardiovascular disease, and type 2 diabetes. Interventions to increase public transit use may be one promising strategy, particularly for low-income communities or populations of color who are disproportionately burdened by health disparities and transportation barriers. This study employs a natural experiment design to evaluate the impacts of a citywide zero-fare transit policy in Kansas City, Missouri, on ridership and health indicators. In Aim 1, comparison to 9 similar cities without zero-fare transit is used to examine differential changes in ridership from 3 years before to 4 years after the adoption of zero-fare. In Aim 2, Kansas City residents are being recruited from a large safety net health system to compare health indicators between zero-fare riders and non- riders. Longitudinal data on BMI, cardiometabolic markers, and economic barriers to health are collected from the electronic health record from 2017 to 2024. Cross-sectional data on healthy eating and device-measured physical activity are collected from a subsample of participants as part of the study procedures ( N = 360). Numerous baseline characteristics are collected to account for differences between Kansas City and comparison city bus routes (Aim 1) and between zero-fare riders and non-riders within Kansas City (Aim 2). Evidence on how zero-fare transit shapes population health through mechanisms related to improved economic factors, transportation, physical activity, and healthy eating among low-income groups is expected., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

- Abstract
Objective: This study reports 3-year effects of a parent-teen cognitive/behavioral treatment for adolescent attention-deficit/hyperactivity disorder (ADHD), blended with Motivational Interviewing (Supporting Teens' Autonomy Daily [STAND]), vs Usual Care (UC) in 4 community clinics., Method: This was a randomized clinical trial with double randomization of adolescents and therapists to STAND vs UC. Participants were 278 culturally diverse adolescents diagnosed with DSM-5 ADHD and 82 community therapists. Long-term effects on outcomes and theorized mechanisms were assessed at approximately 3 years post baseline (mean age = 16.94 years, SD = 1.69): ADHD severity (parent-rated), parent-teen conflict (parent/adolescent-rated), organization, time management, and planning skills (OTP; parent-rated), treatment and school enrollment (parent/adolescent-reported), and ADHD diagnostic persistence (clinician-determined). Therapist licensure was examined as a treatment moderator. Intent-to-treat (ITT) and per protocol analyses (n = 225; participants initiating treatment after agency intake) were conducted., Results: As in the original trial, ITT analyses indicated no long-term group by time effects. However, STAND (vs UC) led to superior long-term outcomes when therapists were licensed (22% of sample) vs unlicensed for parent-rated hyperactivity/impulsivity (d = 0.39; adolescent-rated parent-teen conflict: d = 0.27, and parent-rated OTP skills: d = 0.79). Previously reported post-treatment group differences on medication engagement were non-significant at the 3-year follow-up., Conclusion: Although STAND did not outperform UC overall, group by licensure interactions indicate specific long-term impacts on ADHD symptoms, executive function skills such as OTP, and parent-teen conflict, extending this trial's acute effects and replicating previous findings. Clinicians in community settings might recommend adjunctive cognitive/behavioral treatment to adolescents with ADHD to maximize long-term outcomes.

- Abstract
Introduction: Organophosphate esters (OPEs) are increasing in use as flame retardants and plasticizers and concerns have been raised given their endocrine-disrupting activities and possible obesogenic consequences. However, longitudinal studies on gestational OPE exposure and childhood obesity are scarce. This study examined whether OPE levels in maternal urine during pregnancy were associated with the risk of childhood obesity., Methods: OPEs were analyzed in pregnancy urine samples of 5,087 individuals from 14 studies contributing to the Environmental influences on Child Health Outcomes (ECHO) Cohort. BDCPP, DBUP/DIBP, and DPHP, detected in > 80 % of the samples, were modeled continuously and by tertiles; whereas BCPP, BBOEP, and BCETP, detected in 50-80 % of samples, were modeled categorically (not-detected, low, and high). Childhood obesity was defined by BMI z-score ≥ 95th percentile according to WHO (<2 years) and the CDC (≥2 years) metrics. Adjusted modified Poisson regression models assessed childhood obesity risk and the mixture effect was assessed using Bayesian kernel machine regression (BKMR)., Results: BMI measurements were available for 3,827 children in infancy (0.5-1.9 years), 3,921 children in early childhood (2.0-4.9 years), and 2,541 children in mid-childhood (5.0-10.0 years). Obesity was present in 16-21 % of children across age groups. In mid-childhood DBUP/DIBP second and third versus first tertiles were associated with increased obesity risk (RR 1.14; 95 % CI: 1.02, 1.28; and RR 1.11; 95 % CI: 0.97, 1.27; respectively); whereas BDCPP second and third versus first tertiles reflected an inverse association with obesity risk (RR 0.85; 95 % CI: 0.80, 0.91 and RR 0.91; 95 % CI: 0.77, 1.07; respectively). No association with obesity risk was observed for DPHP, BCPP, BBOEP, and BCETP. Directions observed were consistent with those seen in BKMR models., Conclusions: This study identified mixed associations between gestational OPE exposure and childhood obesity. Further investigation across a comprehensive range of OPE exposures is warranted., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Objective: Describe the healthcare utilization in the last 60 days of life in pediatric patients with cancer who died at home under hospice care and those that died in the hospital. Methods: Retrospective chart review of the medical records of those children with cancer diagnosis with palliative care consult and died either under hospice care at home or in the hospital. Results: Patients dying under hospice care spent a median of 44 days at home. Patients dying in the hospital spent a median of 30.5 days in the hospital, 10.5 days in the intensive care unit, and underwent 3.5 procedures requiring anesthesia. 45% of those that died in the hospital were compassionately extubated. Conclusion: For those dying with a cancer diagnosis, hospice care can allow for significant time at home with minimal healthcare while those dying in the hospital do spend a significant time in the hospital. This provides more information to both providers and families about end-of-life healthcare utilization., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objectives: Recent studies report a fluctuating course of attention-deficit/ hyperactivity disorder (ADHD) across development characterized by intermittent periods of remission and recurrence. In the Multimodal Treatment of ADHD (MTA) study, we investigated fluctuating ADHD including clinical expression over time, childhood predictors, and between- and within-person associations with factors hypothesized as relevant to remission and recurrence., Methods: Children with DSM-5 ADHD, combined type (N = 483), participating in the MTA adult follow-up were assessed 9 times from baseline (mean age = 8.46) to 16-year follow-up (mean age = 25.12). The fluctuating subgroup (63.8% of sample) was compared to other MTA subgroups on variables of interest over time., Results: The fluctuating subgroup experienced multiple fluctuations over 16 years (mean = 3.58 , SD = 1.36) with a 6- to 7-symptom within-person difference between peaks and troughs. Remission periods typically first occurred in adolescence and were associated with higher environmental demands (both between- and within-person), particularly at younger ages. Compared to other groups, the fluctuating subgroup demonstrated moderate clinical severity. In contrast, the stable persistent group (10.8%) was specifically associated with early and lasting risk for mood disorders, substance use problems in adolescence/ young adulthood, low medication utilization, and poorer response to childhood treatment. Protective factors were detected in the recovery group (9.1%; very low parental psychopathology) and the partial remission group (15.6%; higher rates of comorbid anxiety)., Conclusions: In the absence of specific risk or protective factors, individuals with ADHD demonstrated meaningful within-individual fluctuations across development. Clinicians should communicate this expectation and monitor fluctuations to trigger as-needed return to care. During remission periods, individuals with ADHD successfully manage increased demands and responsibilities., Trial Registration: ClinicalTrials.gov identifier: NCT00000388., (© Copyright 2024 Physicians Postgraduate Press, Inc.)

- Abstract
Introduction: Whereas marginal food insecurity has been recognized as important in Canadian food security policy, the category of marginal food security (MFS) is often ignored in US food security research., Methods: Prevalence of FI was estimated according to the conventional and an alternate classification of MFS with food insecurity among 938 youth and young adults (YYA) with youth-onset type 1 diabetes (T1D) and 156 with youth-onset of type 2 diabetes (T2D) from the SEARCH Food Security Cohort Study (2018-2021). Multivariable regression was used to estimate the association of MFS and conventionally defined food insecurity (FI) ascertained with diabetes-related outcomes, including acute diabetes complications, health care utilization, and diabetes self-management among YYA with T1D., Results: MFS affected 10% of participants with T1D diabetes and 20% of participants with T2D. Classifying MFS with FI increased FI prevalence from 18.0% to 27.8% in participants with T1D and 34.6% to 55.1% in participants with T2D. Compared to T1D with high food security, YYA with T1D who were FI had higher odds hypoglycemia (2.1, 95%CI 1.2-3.6) and ketoacidosis (1.6, 95%CI 1.0-2.6), but no association was seen in MFS. The FI group also had higher odds of emergency department use and hospitalization (2.3, 95%CI 1.5-3.4; 2.4, 95%CI 1.5-3.9) and lower odds of technology use and checking glucose (0.6, 95%CI 0.4-0.9; 0.3, 95%CI 0.1-0.6). The MFS group exhibited associations of similar directions., Discussion and Conclusions: Health care providers should consider care of patients with T1D and MFS the same way they care for patients with FI., (Copyright © 2024.

- Abstract
Background: The kinetics and durability of T-cell responses to SARS-CoV-2 in children are not well characterized. We studied a cohort of children aged 6 months to 20 years with COVID-19 in whom peripheral blood mononuclear cells and sera were archived at approximately 1, 6, and 12 months after symptom onset., Methods: We compared antibody responses (n = 85) and T-cell responses (n = 30) to nucleocapsid (N) and spike (S) glycoprotein over time across 4 age strata: 6 months to 5 years and 5-9, 10-14, and 15-20 years., Results: N-specific antibody responses declined over time, becoming undetectable in 26 (81%) of 32 children by approximately 1 year postinfection. Functional breadth of anti-N CD4+ T-cell responses also declined over time and were positively correlated with N-antibody responses (Pearson r = .31, P = .008). CD4+ T-cell responses to S displayed greater functional breadth than N in unvaccinated children and, with neutralization titers, were stable over time and similar across age strata. Functional profiles of CD4+ T-cell responses against S were not significantly modulated by vaccination., Conclusions: Our data reveal durable age-independent T-cell immunity to SARS-CoV-2 structural proteins in children over time following COVID-19 infection as well as S-antibody responses in comparison with declining antibody responses to N., Competing Interests: Potential conflicts of interest.

- Abstract
Background: Adolescents and young adults (AYAs) receiving hematopoietic cell transplantation (HCT) are at high risk of poor psychosocial health. This study aimed to determine whether the Promoting Resilience in Stress Management (PRISM) intervention mitigated these risks during the first 6 months posttransplant., Methods: This multisite, parallel, randomized trial was conducted from April 2019 to March 2023. Eligible AYAs were aged 12-24 years, English speaking, and within 1 month of HCT for cancer or cancer predisposition syndrome. They were assigned 1:1 to PRISM (a brief, skills-based intervention targeting "resilience resources" [stress management, goal setting, cognitive reframing, and meaning making]) or usual care (UC). Outcomes included total symptoms of depression and anxiety (Hospital Anxiety and Depression Scale; primary outcome), hope (Snyder Hope Scale), resilience (10-item Connor-Davidson Resilience Scale), and health-related quality of life (HRQOL; Pediatric Quality of Life Inventory Cancer Module). Analyses leveraged multivariable linear regressions; exploratory analyses assessed the influence of baseline depression or anxiety., Results: Of 94 enrolled and randomized AYAs, the mean age was 16.7 years (SD, 4.2); 43 (46%) were female, 56 (60%) were non-Hispanic White, 22 (23%) were Hispanic, and nine (10%) were Black. Most (77%) had leukemia. Of n = 50 randomized to PRISM and n = 44 to UC, 37 (74%) and 33 (73%) completed all study procedures, respectively. In intention-to-treat analyses, PRISM did not affect 6-month depression and anxiety (β = -1.1; 95% CI, -3.7 to 1.5), hope (β = 0.83; 95% CI, -3.3 to 4.9), resilience (β = -0.01; 95% CI, -3.0 to 3.0), or HRQOL (β = 1.5; 95% CI, -4.7 to 7.9). Among AYAs with preexisting anxiety or depression, PRISM recipients reported greater 6-month improvements in hope (score change, +3.71; SD, 6.9) versus UC recipients (score change, -2.76; SD, 6.5) (p = .04)., Conclusions: Resilience coaching did not influence outcomes in this sample. Exploratory findings suggest it may be more effective when directed toward those with concurrent distress., (© 2024 American Cancer Society.)

- Abstract
The immunocompromised population was disproportionately affected by the severe acute respiratory syndrome coronavirus 2 pandemic. However, these individuals were largely excluded from clinical trials of vaccines, monoclonal antibodies, and small molecule antivirals. Although the community of scientists, clinical researchers, and funding agencies have proven that these therapeutics can be made and tested in record time, extending this progress to vulnerable and medically complex individuals from the start has been a missed opportunity. Here, we advocate that it is paramount to plan for future pandemics by investing in specific clinical trial infrastructure for the immunocompromised population to be prepared when the need arises., Competing Interests: Potential conflicts of interest.
