Rehabilitation of Executive Function in Pediatric Traumatic Brain Injury (REPeaT): Outcomes of a pilot randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of Cogmed Working Memory Training (Cogmed) in improving working memory (WM) and decision making (DM) in childhood traumatic brain injury (TBI), and any associated increases in functional outcomes such as academic achievement in mathematics, behavior, social skills, and quality of life. METHOD: A randomized controlled trial of the Cogmed (RM version) intervention for children with TBI. A total of 69 children post-TBI were screened for WM impairments, of which 31 eligible participants (Mage: 10.6 years; male n = 21) were recruited and randomized to either the treatment group (Cogmed, n = 16) or the active-control group (Lexia Reading Core5, n = 15). Both groups completed computerized training for 5 weeks with clinician support via an online video platform. Immediately posttraining and at 6 months follow-up, primary (WM and DM) and secondary functional outcomes were assessed. RESULTS: Immediately postintervention, significant improvement was found in one primary outcome (WM verbal component) for the Cogmed group, but this was not maintained at the 6 months follow-up. No immediate improvements or maintenance gains (small effect sizes) in other primary outcomes of visuospatial WM or DM were reported in the Cogmed group. No other significant group differences were detected for other functional outcomes. CONCLUSIONS: Despite the limited benefits observed in this small randomized controlled trial, it will be beneficial to investigate Cogmed's efficacy in a case-series methodology, to further determine its effectiveness in a pediatric TBI population. Furthermore, a cautious approach in clinical implementation of Cogmed is advised. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Biopsychosocial correlates of fatigue in young adult survivors of childhood traumatic brain injury: A prospective cohort study.

This prospective cohort study aimed to evaluate the potential role of injury, socio-demographic and individual psychological factors in predicting long-term fatigue outcomes in young adult survivors of childhood TBI at 16-years post-injury. The study included 51 young adults diagnosed with childhood TBI from 2-12 years of age. Twenty age-and-sex-matched controls were included for comparison. Findings showed that almost one-in-four TBI participants (24%) endorsed clinically elevated fatigue at 16-years post-injury. Despite the relatively large proportion of TBI participants endorsing clinically significant fatigue, group comparisons revealed that the TBI and control groups did not significantly differ on fatigue symptom severity or rates of clinically elevated fatigue. For the TBI group, post-injury fatigue was significantly associated with socio-demographic and psychological factors, including lower educational level, higher depression symptom severity, and more frequent substance use. Higher fatigue was also associated with lower self-reported quality of life (QoL) in the physical, psychological, and environmental domains, even after controlling for depressive symptom severity, socio-demographic, and injury-related factors. Overall, findings show that a substantial proportion of young adults with a history of childhood TBI experience clinically elevated fatigue at 16-years post-injury. Identification and treatment of modifiable risk-factors (e.g. depression symptoms, substance use) has potential to reduce fatigue.

The decision-making task: Development and evaluation in a paediatric traumatic brain injury population.

Assessment measures that quantify decision-making abilities in children and adolescents are limited. In the current study, a novel computerized Decision-Making Task (DMT), which identifies the process that is involved in decision-making, was developed based on an existing information-boards paradigm. The overall aim was to validate the DMT in a paediatric TBI population. This prospective study investigated the performance on the DMT for children post-TBI (n = 49; 7-15 years) compared to typically developing controls (n = 22; 7-15 years), and investigated the psychometric properties of the DMT by examining internal consistency-related reliability, convergent validity (measures of decision-making, working memory, functional outcomes, and behaviour), and divergent validity (vocabulary). Significant differences were detected for performance on the DMT between children post-TBI and the control group. Psychometric properties of the DMT were acceptable, with variable findings for convergent validity (working memory, functional outcomes, and behaviour). This is the first study to develop and investigate a novel computerised task to assess decision-making skills in a paediatric TBI population. Results cautiously suggest that the DMT is a valid and a reliable measure of decision-making in our clinical sample.

Longitudinal cohort study investigating neurodevelopmental and socioemotional outcomes in school-entry aged children after open heart surgery in Australia and New Zealand: the NITRIC follow-up study protocol.

INTRODUCTION: Despite growing awareness of neurodevelopmental impairments in children with congenital heart disease (CHD), there is a lack of large, longitudinal, population-based cohorts. Little is known about the contemporary neurodevelopmental profile and the emergence of specific impairments in children with CHD entering school. The performance of standardised screening tools to predict neurodevelopmental outcomes at school age in this high-risk population remains poorly understood. The NITric oxide during cardiopulmonary bypass to improve Recovery in Infants with Congenital heart defects (NITRIC) trial randomised 1371 children <2 years of age, investigating the effect of gaseous nitric oxide applied into the cardiopulmonary bypass oxygenator during heart surgery. The NITRIC follow-up study will follow this cohort annually until 5 years of age to assess outcomes related to cognition and socioemotional behaviour at school entry, identify risk factors for adverse outcomes and evaluate the performance of screening tools. METHODS AND ANALYSIS: Approximately 1150 children from the NITRIC trial across five sites in Australia and New Zealand will be eligible. Follow-up assessments will occur in two stages: (1) annual online screening of global neurodevelopment, socioemotional and executive functioning, health-related quality of life and parenting stress at ages 2-5 years; and (2) face-to-face assessment at age 5 years assessing intellectual ability, attention, memory and processing speed; fine motor skills; language and communication; and socioemotional outcomes. Cognitive and socioemotional outcomes and trajectories of neurodevelopment will be described and demographic, clinical, genetic and environmental predictors of these outcomes will be explored. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Children's Health Queensland (HREC/20/QCHQ/70626) and New Zealand Health and Disability (21/NTA/83) Research Ethics Committees. The findings will inform the development of clinical decision tools and improve preventative and intervention strategies in children with CHD. Dissemination of the outcomes of the study is expected via publications in peer-reviewed journals, presentation at conferences, via social media, podcast presentations and medical education resources, and through CHD family partners. TRIAL REGISTRATION NUMBER: The trial was prospectively registered with the Australian New Zealand Clinical Trials Registry as 'Gene Expression to Predict Long-Term Neurodevelopmental Outcome in Infants from the NITric oxide during cardiopulmonary bypass to improve Recovery in Infants with Congenital heart defects (NITRIC) Study - A Multicentre Prospective Trial'. TRIAL REGISTRATION: ACTRN12621000904875.

The Australian and New Zealand brain injury lifespan cohort protocol: Leveraging common data elements to characterise longitudinal outcome and recovery.

INTRODUCTION: Cognitive, behavioural, academic, mental health and social impairments are common following paediatric traumatic brain injury (TBI). However, studies are often reliant on small samples of children drawn from narrow age bands, and employ highly variable methodologies, which make it challenging to generalise existing research findings and understand the lifetime history of TBI. METHOD AND ANALYSIS: This study will synthesise common data sets from national (Victoria, New South Wales, Queensland) and international (New Zealand) collaborators, such that common data elements from multiple cohorts recruited from these four sites will be extracted and harmonised. Participant-level harmonised data will then be pooled to create a single integrated data set of participants including common cognitive, social, academic and mental health outcome variables. The large sample size (n=1816), consisting of participants with mild, moderate and severe TBI, will provide statistical power to answer important questions that cannot be addressed by small, individual cohorts. Complex statistical modelling, such as generalised estimation equation, multilevel and latent growth models, will be conducted. ETHICS AND DISSEMINATION: Ethics approval was granted by the Human Research Ethics Committee (HREC) of the Royal Children's Hospital (RCH), Melbourne (HREC Reference Number 2019.168). The approved study protocol will be used for all study-related procedures. Findings will be translated into clinical practice, inform policy decisions, guide the appropriate allocation of limited healthcare resources and support the implementation of individualised care.

Paediatric traumatic brain injury and the dysregulation profile: The mediating role of decision-making.

Decision-making is often impacted by paediatric traumatic brain injury (TBI). However, there are few tools available to assess these skills in children, with even less research on the consequences of decision-making deficits on dysregulation following TBI. This prospective preliminary study investigated whether decision-making mediated the effect of TBI on dysregulation in children. The performance of school-aged children aged between 7 and 15 years with TBI (n = 49) and that of typically developing controls (n = 22) was compared on The Decision-making Task, and on parent ratings of the dysregulation profile as characterized by the Child Behaviour Checklist-Dysregulation Profile. Relative to the Control group, the TBI group performed more poorly on the decision-making task, and parents of the TBI group rated their children to be more poorly on the dysregulation profile. Mediation analyses indicated that decision-making mediated the relationship between TBI and the dysregulation profile. Our preliminary findings suggest the need for further research in the area of decision-making, and its impact on dysregulated behaviours in children following TBI.

Association of Endocrine Therapy Initiation Timeliness With Adherence and Continuation in Low-Income Women With Breast Cancer.

Importance: Though adjuvant endocrine therapy (AET) has proven efficacy in treating hormone receptor-positive (HR-positive) breast cancer, patient adherence to AET and continuation of treatment as recommended by guidelines remain suboptimal, especially for low-income patients. Objective: To quantify timelines for initiating AET and assess their association with short- and long-term adherence and continuation of AET in low-income women with breast cancer. Design, Setting, and Participants: This population-based retrospective cohort study included women younger than 65 years diagnosed with first primary HR-positive breast cancer between January 1, 2007, and December 31, 2013, followed up for 5 years after the first use of AET through December 2018, and identified from the linked Missouri Cancer Registry and Medicaid claims data set. Exposures: Time to initiation (TTI) as days from the date of last treatment (surgery, radiotherapy, or chemotherapy) to the first date of AET prescription fill. Main Outcomes and Measures: The main outcomes were adherence to AET as medication possession ratio of 80% or greater and continuation of AET as no gap in medication supply for at least 90 days. Odds ratios (ORs) of adherence and continuation over 1 to 5 years were estimated using logistic regression adjusted for demographic, clinical, and neighborhood variables. Analyses were performed between September 1, 2020, and May 31, 2022. Results: Among 1711 patients, median TTI was 53 (IQR, 26-117) days. A total of 1029 patients (60.1%) were aged 50 to 64 years old, 1270 (74.2%) were non-Hispanic White, and 1133 (66.2%) were unmarried. In the first year after initiation, 1317 (77.0%) were adherent and 1015 (59.3%) continued AET. Over the full 5 years, 376 (22.0%) were adherent and 409 (23.9%) continued AET. Longer TTI was significantly associated with poorer adherence at every year, with an OR of 0.97 (95% CI, 0.95-0.99) for 1-year adherence and an OR of 0.94 (95% CI, 0.90-0.97) for 5-year adherence per 1-month increase in TTI. Longer TTI was also associated with lower odds of short-term, but not long-term, continuation (OR, 0.97 [95% CI, 0.95-0.99] for 1-year continuation and 0.98 [95% CI, 0.96-0.99] for 2-year continuation). Conclusions and Relevance: In this cohort study, longer time to AET initiation was associated with lower odds of short-term and long-term adherence to AET in Medicaid-insured patients with breast cancer. Therefore, early interventions targeting treatment initiation timelines may positively impact adherence throughout the course of treatment and, therefore, outcomes.

Pediatricians' knowledge, attitudes and practices surrounding menstruation and feminine products.

OBJECTIVE: This study investigates whether primary care pediatricians adhere to the American Academy of Pediatrics (AAP) recommendations by routinely evaluating patients' menstrual cycles and educating patients about menstruation and feminine products. Additionally, this study examines pediatricians' knowledge and attitudes surrounding menstrual health topics. METHODS: A 53-item online questionnaire was developed to evaluate pediatricians' knowledge, attitudes and clinical practices regarding menstruation-related topics. The questionnaire was emailed to 2500 AAP members using a geographically-stratified sampling approach, with pediatricians in each state selected randomly. Mann-Whitney U tests, t-tests, and logistic regressions were used to assess associations between correlates and pediatricians' knowledge, attitudes and practices. RESULTS: Five hundred and eighteen out of 2500 pediatricians participated (response rate = 20.7%), 462 met inclusion criteria; 78.8% were female, 79.2% were Caucasian. The majority of the pediatricians (58.2%) were "not at all" or only "slightly" familiar with the AAP guidelines on anticipatory guidance surrounding menarche. Many reported they do not routinely provide anticipatory guidance regarding menstruation to pre-menarchal patients (24.7%), discuss menstruation with post-menarchal patients (33.1%) or ask patients the date of their last period (28.4%). The majority were unlikely to discuss feminine products with patients. Gaps in menstruation-related knowledge were noted. Male pediatricians were significantly less likely to evaluate patients' menstrual cycles and provide patient-education regarding menstruation-related topics, and had significantly lower self-rated and measured knowledge of these topics. CONCLUSIONS: A concerning number of pediatricians in a national sample do not abide by AAP recommendations surrounding menstruation and exhibit knowledge gaps in this area. To effectively address the health needs of female patients, pediatricians should better incorporate menstrual health care into their clinical practice.

Paging Dr. Google: The Effect of Online Health Information on Trust in Pediatricians' Diagnoses.

This study investigates how parental trust in physician diagnoses and likelihood of seeking a second opinion (SO) are affected by Internet sources. In an anonymous survey, 1374 parents of minors viewed a vignette describing their child's symptoms followed by Internet results that either supported or contradicted the pediatrician's diagnosis (Dx). A control group did not view any Internet results. After learning the Dx, participants rated trust in the Dx and likelihood of seeking a SO on a 7-point Likert-type scale. Participants who viewed contradicting results were less likely to trust the Dx ( P < .001) and more likely to seek a SO than the control ( P < .001). Participants who viewed supporting results were more likely to trust the Dx ( P < .001) and less likely to seek a SO than the control ( P < .001). Physicians must be aware of the influence the Internet may have on patients' trust.

Rehabilitation of Executive function in Paediatric Traumatic brain injury (REPeaT): protocol for a randomized controlled trial for treating working memory and decision-making.

BACKGROUND: Working memory allows us to hold information in an active state for short periods of time, and is essential in facilitating goal directed cognitive functioning. Difficulties in working memory and decision-making are common post childhood Traumatic Brain Injury (TBI). Despite this, there is a paucity of research pertaining to implementation and effectiveness of interventions to reduce these common difficulties which impact significantly on one's ability to function independently. One such intervention, Cogmed Working Memory Training Program, has shown success in improving working memory in other childhood clinical populations, but has received little evaluation in the TBI area. This study aims to evaluate whether Cogmed improves working memory and decision-making post childhood TBI and whether these benefits generalize to functional areas. METHODS: The study is a randomized controlled trial (RCT) of the Cogmed (RM version) intervention for children post-TBI. Children aged 7-15 years are initially screened for working memory impairments. Eligible participants are then randomized into either the treatment group (Cogmed) or the active-control group (Lexia Reading). Each group trains online for 50 min each day, 5 days per week, for 5 consecutive weeks. The online training is supported by online clinician meetings each week. Outcome neuropsychological and functional assessments are carried out immediately at the completion of the intervention and at 6 months follow-up. DISCUSSION: This study follows gold standard methodology in intervention research; uses a novel measure of decision-making; measures the effects of intervention on functional outcomes immediately and longer-term post intervention; uses online clinician support in order to allow more families easy access to the program; and promotes the use of technology to improve health services. If efficacious in improving working memory, decision-making, and functional outcomes, our team will then take a key role in implementing Cogmed into clinical care.

Leveraging electronic health records to assess the role of ADRB2 single nucleotide polymorphisms in predicting exacerbation frequency in asthma patients.

Asthma is the leading chronic disease in children. Several studies have identified genetic biomarkers associated with susceptibility and severity in both adult and pediatric cases. In this study, we evaluated outcomes in 400 African American and European American pediatric cases all of whom were regular users of inhaled corticosteroids. Patients were stratified by genotype using two single nucleotide polymorphisms in the ß-2-adrenergic receptor (ADRB2) gene - rs1042713 and rs1042714, previously associated with asthma outcome. These correspond to nonsynonymous single nucleotide polymorphisms at positions 16 [arginine to glycine (Arg16Gly); rs1042713] and 27 [glutamic acid to glutamine (Glu27Gln); rs1042714], which are relatively common (minor allele frequencies ∼40-50%), and have been well characterized in asthma pharmacogenetics. We controlled for adherence to the National Heart, Lung and Blood Institute guidelines using deep mining of electronic health record data to determine treatment course. We found no significant effect for rs1042713 (Arg16Gly) but did identify an effect for rs1042714, where participants homozygous for Gln27 had increased exacerbations while taking inhaled corticosteroids in comparison with those who were either heterozygous or homozygous for Glu27. This is consistent with previous studies and demonstrates for the first time that the Glu27 variant in the ADRB2 gene is associated with increased frequencies of asthma exacerbations. Moreover, this study also lends an important proof-of-principle on how electronic health records linked to genotype can be efficiently and systematically mined to delineate health outcomes.

Fatigue following Paediatric Acquired Brain Injury and its Impact on Functional Outcomes: A Systematic Review.

Fatigue is a commonly reported sequela following an acquired brain injury (ABI), and can have a negative impact on many areas of a child's life. However, there is minimal research that focuses on fatigue specifically, and so factors such as its occurrence, duration, and impact on functioning remain uncertain. This systematic review aims to provide a comprehensive summary of the research to date, bringing together a number of studies with a focus on paediatric ABI and fatigue. Terms were searched in relevant databases (PsycInfo, Medline, CINAHL), and articles were included or excluded based on specified criteria. Of the 1177 papers identified in the original search, a total of 9 papers met inclusion criteria, and were categorised as traumatic brain injury (TBI; n = 4), meningitis and meningococcal disease (n = 2), brain tumours (n = 2), and mixed ABI group (n = 1). Key findings suggest that fatigue is a problem encountered by a significant proportion of patients in all the studies reviewed, and often occurred regardless of the cause; fatigue was also associated with poor academic achievement, limited physical activity, and social and emotional problems. Injuries of greater severity were associated with higher levels of fatigue and worse outcomes. Several management options were suggested, though their efficacy was not reported. Future research is required with a suggested focus on using multiple time points to better understand the trajectories of fatigue following childhood ABI, and to build an evidence base to determine which management options are most suitable.
