    Abstract Purpose: This study aims to quantify heading exposure in real-life elite football at the level of individual male and female adolescents, young adults, and adults.
    Methods: Heading exposure was determined by video analysis in combination with a structured electronic registration tool and observation training, to comprehensively register heading characteristics. Characteristics of heading events were registered in 116 official matches (96 male, 20 female) of Dutch national teams.
    Results: Mean exposure for male players based on full match participation was 4.2 headers, with maximum heading exposure at 10.6 headers. Mean heading exposure was higher in adult than adolescent players ( P = 0.049), whereas maximum heading exposure was higher for adult than for young adult players ( P = 0.045). Maximum heading exposure was higher in male than in female players ( P = 0.015). Defenders had the greatest mean and maximum heading exposure ( P < 0.001). Longer flight courses of the ball had greater contribution to mean and maximum heading exposure than shorter courses ( P < 0.01). Frontal headers had greater contribution to exposure than other points of contact on player's head ( P < 0.001), whereas linear headers had greater contribution than rotational headers ( P = 0.016). Defensive headers had greater contribution to exposure than other heading types ( P < 0.014). Unintentional head contacts in elite football players were, in most cases (80%), not related to heading situations.
    Conclusions: This study provides real-life quantifications of mean and maximum heading exposure in elite football, with strong relevance for policy makers and researchers. The results highlight the roles of player and heading characteristics in heading exposure, informing current discussions on the role of heading in football.

    Abstract Adolescence is characterized by profound changes in body and behavior, and not surprisingly during this developmental phase the risk of developing psychosocial problems increases dramatically. The purpose of the current study was to examine the relationship of both physical fitness and body composition with psychosocial health in adolescents (12-15 years). Data were collected in 2019-2020 in a representative sample of 361 Dutch adolescents (46.3% boys, age = 13.44 ± 0.43 years). Physical fitness and body composition were assessed by subtests of the Eurofit test battery assessing cardiorespiratory fitness (20 m Shuttle Run Test), muscular fitness (Broad Jump and Sit-Ups), speed-agility (10x5-m Shuttle Run Test and Fast Tapping Test), and body composition (Body Mass Index). Psychosocial health was assessed in four domains: self-concept (Competence Experience Scale for Adolescents), symptoms of depression (Child Depression Inventory), anxiety (State and Trait Anxiety Inventory) and ADHD (Strengths and Weaknesses of ADHD Symptoms). Multilevel regression analyses were performed in MLwin. Results showed that better cardiorespiratory fitness was related to better self-concept (β = 0.225; p < 0.001), less symptoms of depression (β = -0.263; p = 0.003), and lower levels of state (β = -0.239; p = 0.008) and trait anxiety (β = -232; p = 0.008). Furthermore, higher BMI was related to lower self-concept (β = -0.075; p = 0.019). Taken together, the results suggest that better cardiorespiratory fitness and lean body composition have a positive relationship with self-concept and that better cardiorespiratory fitness is related to less symptoms of depression and anxiety.

    Abstract Conventional neurocognitive assessment does not account for the complex interplay between neurocognitive functions that gives rise to (goal-directed) behavior. This study aims to explore the value of the application of network analysis to individual neurocognitive data, in order to investigate neurocognitive network organization (i.e., the neurocognome). Participants were healthy young adults (N = 51, average age: 26 years [range: 18-34], 49% female) that underwent a single comprehensive neurocognitive assessment. To allow implementation of network analysis, we developed a new measure of connectivity between neurocognitive functions that can be calculated on a single neurocognitive assessment. Connectivity values between all possible pairs of neurocognitive functions were used to reconstruct individual neurocognitive networks. Graph theory was applied to extract measures of global and local network organization from neurocognitive networks at the individual level. The results confirmed the expectation that neurocognitive connectivity values should be higher for connections between neurocognitive functions that are more closely related (i.e., within neurocognitive domains) than for connections between neurocognitive functions that are less closely related (i.e., across neurocognitive domains). The results further showed that reconstruction of the neurocognitive network at the individual level has considerable agreement with a group-based approach, providing preliminary evidence for the validity of our approach. The reconstructed neurocognitive network also showed considerable consistency among (randomly selected) independent subgroups, supporting the stability of our approach. Lastly, neurocognitive network parameters were related to intelligence and behavior problems, reflecting relevance of neurocognitive network organization for other important domains of functioning. Moreover, local network parameters (i.e., the relative importance of neurocognitive functions in the network) may have stronger relevance for behavioral functioning than conventional measures of neurocognitive functioning (i.e., z-scores reflecting performance on individual neurocognitive tests). Taken together, this study indicates that analysis of individual neurocognitive network organization has potential value for neurocognitive assessment in research and clinical practice.

    Abstract Cognitive impairments, common sequelae of acquired brain injury (ABI), significantly affect rehabilitation and quality of life. Currently, there is no solid evidence-base for pharmacotherapy to improve cognitive functioning after ABI, nevertheless off-label use is widely applied in clinical practice. This meta-analysis and meta-regression aims to quantitatively aggregate the available evidence for the effects of pharmacological agents used in the treatment of cognitive impairments following ABI. We conducted a comprehensive search of Embase, Medline Ovid, and Cochrane Controlled Trials Register databases for randomized controlled and crossover trials. Meta-analytic effects were calculated for each pharmaceutical agent and targeted neuromodulator system. Cognitive outcome measures were aggregated across cognitive domains. Of 8,216 articles, 41 studies (4,434 patients) were included. The noradrenergic agent methylphenidate showed a small, significant positive effect on cognitive functioning in patients with traumatic brain injury (TBI; k = 14, d = 0.34, 95% confidence interval: 0.12-0.56, P = 0.003). Specifically, methylphenidate was found to improve cognitive functions related to executive memory, baseline speed, inhibitory control, and variability in responding. The cholinergic drug donepezil demonstrated a large effect size, albeit based on a limited number of studies (k = 3, d = 1.68, P = 0.03). No significant effects were observed for other agents. Additionally, meta-regression analysis did not identify significant sources of heterogeneity in treatment response. Our meta-analysis supports the use of methylphenidate for enhancing cognitive functioning in patients with TBI. Although donepezil shows potential, it warrants further research. These results could guide clinical decision making, inform practice guidelines, and direct future pharmacotherapeutic research in ABI.

    Abstract Mild traumatic brain injury (mTBI) is highly prevalent in children. Recent literature suggests that children with mTBI are at considerable risk of persisting neurocognitive deficits, threatening post-injury child development. Nevertheless, clinical tools for early identification of children at risk are currently not available. This systematic review aims to describe the available literature on neurocognitive outcome prediction models in children with mTBI. Findings are highly relevant for early identification of children at risk of persistent neurocognitive deficits, allowing targeted treatment of these children to optimize recovery. The electronic literature search was conducted in PubMed, EMBASE, CINAHL, Cochrane, PsychINFO and Web of Science on February 9, 2022. We included all studies with multi-variate models for neurocognitive outcome based on original data from only children (age <18 years) with mTBI. Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, two authors independently performed data extraction and risk of bias analysis using the Prediction model Risk of Bias Assessment Tool (PROBAST). This systematic review identified eight original studies (nine articles) reporting prediction models for neurocognitive outcome, representing a total of 1033 children diagnosed with mTBI (mean age at injury = 10.5 years, 37.6% girls). Neurocognitive outcome assessment took place between 1 month and 7 years post-injury. Models were identified with significant predictive value for the following outcomes: memory, working memory, inhibition, processing speed, and general neurocognitive functioning. Prediction performance of these models varied greatly between weak and substantial (

    Abstract Previous studies into associations between physical, neurocognitive and academic skills have reported inconsistent results. This study aimed to get more insight into these relations by examining all three domains simultaneously, testing a complete mediational model including measures of physical competencies (cardiovascular fitness and motor skills), neurocognitive skills (attention, information processing, and core executive functions), and academic achievement (reading, mathematics, and spelling). Dutch primary school students (n = 891, 440 boys, mean age 9.17 years) were assessed on the Shuttle Run Test (cardiovascular fitness), items of the Körperkoordinationstest für Kinder and Bruininks-Oseretsky Test-II (fundamental motor skills), computerized neurocognitive tests, and standardized academic achievement tests. A multilevel structural equation model showed that physical competencies were only indirectly related to academic achievement, via specific neurocognitive functions depending on the academic domain involved. Results provide important implications, highlighting the importance of well-developed physical competencies in children.

    Abstract Introduction: Hirschsprung-associated enterocolitis (HAEC) accounts for substantial morbidity and mortality in patients with Hirschsprung disease (HD). The aim of this study was to identify incidence of pre- and postoperative HAEC in our consecutive cohort and to identify patient and clinical characteristics that are associated with developing postoperative HAEC and HAEC-free interval.
    Material and methods: A retrospective cohort study was performed with all 146 HD patients treated between 2000 and 2017. Data were retrieved from the medical records. HAEC was defined as presence of clinical signs of bowel inflammation, that required treatment with intravenous antibiotics and admittance to the hospital during at least two days. To identify risk factor for HAEC, patients with and without a history of postoperative HAEC were compared. Kaplan-Meier and Cox-regression were used to assess HAEC free intervals before and after surgery.
    Results: Out of 146 patients, 12 patients had pre-operative HAEC (8%) and 31 patients had postoperative HAEC (21%). Median preoperative HAEC free interval was 112 days (IQR 182 days). Length of hospital stay due to readmissions was longer for patients with a history of postoperative HAEC compared to patients without a history of postoperative HAEC (9.5 vs 16 days, U = 1872.5, p = 0.047). Median postoperative HAEC free interval was 226 days. Of the patients who had postoperative HAEC, 66% had their first episode within the first year after surgery and that the incidence of HAEC declined over follow-up.
    Conclusions: HAEC incidence was relatively low in our population. No patient or clinical characteristics were associated with the risk of postoperative HAEC.

    Abstract Background: Patients with Hirschsprung disease (HD) mostly undergo surgery around the age of three to six months. While awaiting surgery, therapy to treat the obstruction such as transanal irrigation (TAI) or laxatives is applied. The aim of this study was to gain insight in the prevalence and severity of complications occurring while awaiting surgery and to identify patient characteristics associated with the development of these complications.
    Methods: This study retrospectively analyzed data of patients with HD operated in our center between 2000 and 2021. Complications emerging while awaiting surgery were graded using Clavien-Dindo (CD). Patient characteristics as predictor of a complication were tested using logistic regression analysis.
    Results: Twenty-two of 132 (17%) included patients (preoperative treatment: 94% TAI; 2% laxatives; 2% other therapy) developed 45 complications while awaiting surgery, including predominantly major complications (91%). Bowel perforation occurred most frequently (n = 9, 7%) wherefrom six caused by TAI (5%), including three patients with total colon aganglionosis (TCA) (2%) counting one life-threatening and one lethal perforation. The other perforations were caused by meconium ileus (n = 2) and Hirschsprung associated enterocolitis (HAEC) (n = 1). Other frequent complications were: sepsis (5%), ileus (4%) and persistent obstruction (4%). Predictive factor for developing complication was TCA (OR 9.905, CI 2.994-32.772, p < 0.001).
    Conclusion: We found a complication rate of 17% in patients while awaiting surgery, reporting bowel perforation most frequently. We found this complication in patients with TCA being highly dangerous causing one life-threatening and one lethal perforation. Therefore, we advise in patients with (suspected) TCA to limit the time awaiting surgery.
    Level of evidence: level III.
