RESUMO

BACKGROUND: Very preterm infants are at elevated risk for neurodevelopmental delays. Earlier prediction of delays allows timelier intervention and improved outcomes. Machine learning (ML) was used to predict mental and psychomotor delay at 25 months. METHODS: We applied RandomForest classifier to data from 1109 very preterm infants recruited over 20 years. ML selected key predictors from 52 perinatal and 16 longitudinal variables (1-22 mo assessments). SHapley Additive exPlanations provided model interpretability. RESULTS: Balanced accuracy with perinatal variables was 62%/61% (mental/psychomotor). Top predictors of mental and psychomotor delay overlapped and included: birth year, days in hospital, antenatal MgSO4, days intubated, birth weight, abnormal cranial ultrasound, gestational age, mom's age and education, and intrauterine growth restriction. Highest balanced accuracy was achieved with 19-month follow-up scores and perinatal variables (72%/73%). CONCLUSIONS: Combining perinatal and longitudinal data, ML modeling predicted 24 month mental/psychomotor delay in very preterm infants ½ year early, allowing intervention to start that much sooner. Modeling using only perinatal features fell short of clinical application. Birth year's importance reflected a linear decline in predicting delay as birth year became more recent. IMPACT: Combining perinatal and longitudinal data, ML modeling was able to predict 24 month mental/psychomotor delay in very preterm infants ½ year early (25% of their lives) potentially advancing implementation of intervention services. Although cognitive/verbal and fine/gross motor delays require separate interventions, in very preterm infants there is substantial overlap in the risk factors that can be used to predict these delays. Birth year has an important effect on ML prediction of delay in very preterm infants, with those born more recently (1989-2009) being increasing less likely to be delayed, perhaps reflecting advances in medical practice.

RESUMO

Neurodevelopmental disorders are on the rise worldwide, with diagnoses that detect derailment from typical milestones by 3 to 4.5 years of age. By then, the circuitry in the brain has already reached some level of maturation that inevitably takes neurodevelopment through a different course. There is a critical need then to develop analytical methods that detect problems much earlier and identify targets for treatment. We integrate data from multiple sources, including neonatal auditory brainstem responses (ABR), clinical criteria detecting autism years later in those neonates, and similar ABR information for young infants and children who also received a diagnosis of autism spectrum disorders, to produce the earliest known digital screening biomarker to flag neurodevelopmental derailment in neonates. This work also defines concrete targets for treatment and offers a new statistical approach to aid in guiding a personalized course of maturation in line with the highly nonlinear, accelerated neurodevelopmental rates of change in early infancy.

RESUMO

Neurodevelopmental disorders are on the rise, yet their average diagnosis is after 4.5 years old. This delay is partly due to reliance on social-communication criteria, which require longer maturation than scaffolding elements of neuromotor control. Much earlier criteria could include reflexes, monitoring of the quality of spontaneous movements from central pattern generators and maturation of intentional movements and their overall sensation. General Movement Assessment (GMA) studies these features using observational means, but the last two decades have seen a surge in digital tools that enable non-invasive, continuous tracking of infants' spontaneous movements. Despite their importance, these tools are not yet broadly used. In this work, using CiteSpace, VOSViewer and SciMAT software, we investigate the evolution of the literature on GMA and the methods in use today, to estimate how digital techniques are being adopted. To that end, we created maps of key word co-occurrence networks, co-author networks, document co-citation analysis and strategic diagrams of 295 publications based on a search in the Web of Science, Dimensions and SCOPUS databases for: 'general movement assessment' OR 'general movements assessment'. The nodes on the maps were categorized by size, cluster groups and year of publication. We found that the state-of-the-art methodology to diagnose neurodevelopmental disorders still relies heavily on observation. Several groups in classical GMA research have branched out to incorporate new techniques, but few groups have adopted digital means. We report on additional analyses of methods and biosensors usage and propose that combining traditional clinical observation criteria with digital means may allow earlier diagnoses and interventional therapies for infants.

RESUMO

Female orgasm has been a mystery that psychologists have been attempting to understand for decades. Many have contended that female orgasm is a functionless by-product of male orgasm, while others have argued that female orgasm may be an adaptation in its own right, offering several adaptationist accounts of female orgasm. In the current research, we tested predictions derived from two hypotheses regarding adaptive functions of female orgasm: female orgasm indicates partner mate value or female orgasm promotes long-term, pair bonding. 199 female undergraduates participated in an experiment where they imagined themselves as a member of a romantic relationship provided in a scenario. Within these scenarios, the relationships varied between either short- or long-term and the frequency that the female experienced orgasm during intercourse varied between never, occasionally, and almost always. Participants answered questions regarding relationship satisfaction and perceptions of the fictional relationship. A series of analysis of variance (ANOVAs) indicated that females assigned to conditions of experiencing more frequent orgasms reported greater relationship satisfaction, across both short- and long-term relationships. The relationship between female orgasm frequency and relationship satisfaction was fully mediated by the female's perceived love for her hypothetical partner but not by perceptions of her hypothetical partner's commitment. Taken together, this study provides preliminary support for the hypothesis that female orgasm evolved as a mate-selection tool for females and promotes long-term, pair bonding but does not provide support for the hypothesis that female orgasm evolved as an indicator of male value.

RESUMO

BACKGROUND: Schizophrenia is a persistent psychotic disorder often accompanied by severe disability and premature mortality. New pharmacological treatments are urgently needed. Sodium benzoate, a common food preservative holds potential to be an effective, accessible treatment for schizophrenia, though the optimal dosing and mechanism of action of the compound requires further investigation. METHODS: Individuals with persistent treatment-refractory schizophrenia (n=52) will be recruited. Patients will be randomised in a 1:1:1:1 ratio to receive treatment of one of three active doses (1000, 2000 or 4000 mg daily) of sodium benzoate or placebo for 6 weeks duration. The primary outcome measurement is change in the Positive and Negative Syndrome Scale (PANSS) total score. Secondary outcome measurements are PANSS subscales, Global Assessment of Function (GAF), Clinical Global Impression (CGI) and Patient Global Impression (PGI-I). Change in concentrations of peripheral amino acids (D-alanine, L-alanine, D-serine, L-serine, glycine and glutamate), plasma sodium benzoate, plasma catalase, 3-nitrotyrosine, malondialdehyde and high-sensitivity C-reactive protein (hs-CRP) will be determined as tertiary measures. DISCUSSION: This trial seeks to build upon previous research indicating potential efficacy of sodium benzoate for reduction of symptoms in individuals with treatment-refractory schizophrenia. The trial aims to improve the understanding of the mechanism of action of the compound. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12621000327886 .

RESUMO

Background and Purpose: The aims of this study were to assess the prevalence of multidimensional fatigue symptoms 5 years after pediatric arterial ischemic stroke and identify factors associated with fatigue. Methods: Thirty-one children (19 males) with pediatric arterial ischemic stroke, participating in a larger prospective, longitudinal study, were recruited to this study at 5 years poststroke. Parent- and self-rated PedsQL Multidimensional Fatigue Scale scores were compared with published normative data. Associations between parent-rated PedsQL Multidimensional Fatigue Scale, demographics, stroke characteristics, and concurrent outcomes were examined. Results: Parent-rated total, general and cognitive fatigue were significantly poorer than population norms, with more than half of all parents reporting fatigue symptoms in their children. One-third of children also reported experiencing fatigue symptoms, but their ratings did not differ significantly from normative expectations, as such, all further analyses were on parent ratings of fatigue. Older age at stroke and larger lesion size predicted greater general fatigue; older age, female sex, and higher social risk predicted more sleep/rest fatigue. No significant predictors of cognitive fatigue were identified and only older age at stroke predicted total fatigue. Greater fatigue was associated with poorer adaptive functioning, motor skills, participation, quality of life, and behavior problems but not attention. Conclusions: Fatigue is a common problem following pediatric arterial ischemic stroke and is associated with the functional difficulties often seen in this population. This study highlights the importance of long-term monitoring following pediatric arterial ischemic stroke and the need for effective interventions to treat fatigue in children.

RESUMO

OBJECTIVES: Neonates with respiratory failure are ideally supported with veno-venous rather than veno-arterial extracorporeal membrane oxygenation due to the reduced rate of neurologic complications. However, the proportion of neonates supported with veno-venous extracorporeal membrane oxygenation is declining. We report multisite veno-venous extracorporeal membrane oxygenation, accessing the neck, returning to the inferior vena cava via the common femoral vein in neonates and children less than 10 kg. DESIGN: Retrospective case series with 1 year minimum follow-up. PATIENTS: Patients less than 10 kg supported with veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein. SETTING: A 30-bed pediatric intensive care delivering extracorporeal membrane oxygenation to approximately 20 children annually. INTERVENTIONS: Veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein was delivered using two single lumen cannulae. MEASUREMENTS AND MAIN RESULTS: January 2015 to August 2019, 11 patients underwent veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein with median weight of 3.6 kg (interquartile range 2.8-6.1 kg), and median corrected gestational age of 13 days (interquartile range, 2-175 d). The smallest patient weighed 2.1 kg. Seven patients had comorbidities. Extracorporeal membrane oxygenation was technically successful in all patients with median flows of 126 mL/kg/min (interquartile range, 120-138 mL/kg/min) and median arterial oxygenation saturation of 94% (interquartile range, 91-98%) at 24 hours. Nine survived to home discharge, and two were palliated. Common femoral vein occlusion was observed in all patients on ultrasound post decannulation. There was no clinical or functional deficit in the cannulated limb at follow-up, a minimum of 1 year post extracorporeal membrane oxygenation. CONCLUSIONS: Veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein was performed safely in patients under 10 kg with the smallest patient weighing 2.1 kg. Although occlusion of the common femoral vein was observed in patients post decannulation, subsequent follow-up demonstrated no clinical implications. We challenge current practice that veno-venous extracorporeal membrane oxygenation accessing the jugular and returning to the femoral vein cannot be performed in nonambulatory patients and suggest that this strategy is preferred over veno-arterial extracorporeal membrane oxygenation in infants requiring extracorporeal membrane oxygenation for respiratory failure.

RESUMO

Background and Purpose: Childhood and adolescence coincide with rapid maturation of distributed brain networks supporting social cognition; however, little is known about the impact of early ischemic brain insult on the acquisition of these skills. This study aimed to examine the influence of arterial ischemic stroke (AIS) on facial emotion recognition and theory of mind (ToM) abilities of children and adolescents initially recruited to a single-center, prospective longitudinal study of recovery following AIS. Methods: The study involved 67 participants, including 30 children with AIS (mean time since stroke=5 years) and 37 age-matched typically developing controls who were assessed on measures of cognitive ToM, facial emotion recognition, and affective ToM. Acute clinical magnetic resonance imaging, including diffusion-weighted imaging sequences, were used to evaluate prospective structure-function relationships between acute lesion characteristics (size, location, and arterial territories affected) and long-term social cognitive abilities. Results: Relative to age-matched typically developing controls, children with AIS showed significantly worse performance on measures of basic facial emotion processing, cognitive ToM, and affective ToM. In univariate models, poorer ToM was associated with larger infarcts, combined cortical-subcortical pathology, and involvement of multiple arterial territories. In multivariate analyses, larger lesions and multiterritory infants were predictive of ToM processing but not facial emotion recognition. Poorer cognitive ToM predicted less frequent prosocial behavior and increased peer problems. Conclusions: Social cognitive skills appear vulnerable to disruption from early ischemic brain insult. In the first study to examine social cognition in a prospective cohort of children with AIS, our findings suggest that acute magnetic resonance imaging-based lesion characteristics may have predictive value for long-term social cognitive outcomes and may assist to identify children at elevated risk for social cognitive dysfunction.

RESUMO

Importance: There is evidence that sodium benzoate (BZ) may be an effective adjunctive treatment for schizophrenia. The clinical efficacy of BZ has been investigated in chronic schizophrenia; however, the efficacy of this agent has not been studied in individuals with early psychosis. Objective: To examine the clinical efficacy of the adjunctive use of BZ for symptoms in people with early psychosis. Design, Setting, and Participants: Using a placebo-controlled double-masked parallel-group design, this randomized clinical trial was conducted from August 2015 to July 2018. Participants aged between 15 and 45 years experiencing early psychosis were enrolled from 5 major clinical sites in Queensland, Australia. Data analysis was conducted from October 2018 to February 2020. Interventions: Participants were randomized 1:1 (50 participants in each group) to receive 500 mg of sodium benzoate twice daily or placebo for 12 weeks. Main Outcomes and Measures: The primary efficacy outcome was the Positive and Negative Syndrome Scale (PANSS) total score at 12 weeks. The key secondary efficacy measures were (1) the Clinical Global Impression score, (2) the Hamilton Depression Rating Scale for depression, (3) functioning as assessed by the clinician-rated Global Assessment of Function, and (4) the Assessment of Quality of Life Scale. The PANSS subscale scores and impact on selected amino acid concentrations were also assessed. Results: The study comprised 100 participants with a mean (SD) age of 21.4 (4.1) years, of whom 73 (73%) were male individuals. The mean (SD) baseline PANSS score was 75.3 (15.4). We found no improvement in total PANSS score in the BZ group compared with the placebo group. The end result of least-squares mean difference (SE) for total PANSS was -1.2 (2.4) (P = .63). There were no differences in any subscales of the PANSS, any secondary measures, nor any amino acid concentrations. The dose of BZ was well tolerated without any clinically significant treatment-emergent adverse event differences between BZ and placebo groups. Conclusions and Relevance: In this randomized clinical trial, there was no evidence that adjunctive use of 500 mg of BZ twice daily is an effective treatment for individuals with early psychosis.

RESUMO

BACKGROUND: Deficits in social cognition are common in people with schizophrenia and are associated with impaired functioning. Finding effective interventions to address these deficits is a priority. Social Cognition Interaction Training (SCIT) is a psychosocial intervention that has demonstrated acceptability and feasibility in various health care settings. Larger, well-designed randomized controlled trials are needed to examine the effectiveness of this intervention. DESIGN: A randomized controlled trial. METHODS: One hundred and twenty adults diagnosed with schizophrenia spectrum disorder were randomized to receive SCIT (n = 61) or Befriending Therapy (BT) (n = 59). Both intervention groups were delivered weekly for 2 hr over 12 weeks. Neurocognitive assessment was completed at baseline. Participants completed assessments of social cognition, social functioning, and meta-cognition at baseline, post-intervention, and 3-month follow-up. RESULTS: There were no clinically significant differences between group outcomes on any measure of social cognition or social functioning. There was a trend for both groups to improve over time but not at a level of statistical significance. CONCLUSIONS: SCIT did not show any additional benefits on measures of social cognition compared to Befriending Therapy for people with schizophrenia spectrum disorder. The findings are discussed in terms of potential improvements to the programme. PRACTITIONER POINTS: Effective interventions for the social cognitive deficits of schizophrenia spectrum disorders are still being refined. Social Cognition Interaction Training is a promising therapy but requires further modifications to improve its effectiveness.

RESUMO

BACKGROUND: Neonatal jaundice (NNJ) is common in sub-Saharan Africa (SSA), and it is associated with sepsis. Despite the high incidence, little has been documented about developmental impairments associated with NNJ in SSA. In particular, it is not clear if sepsis is associated with greater impairment following NNJ. METHODS: We followed up 169 participants aged 12 months (57 cases and 112 controls) within the Kilifi Health Demographic Surveillance System. The diagnosis of NNJ was based on clinical laboratory measurement of total serum bilirubin on admission, whereas the developmental outcomes were assessed using the Developmental Milestones Checklist and Kilifi Development Inventory. RESULTS: There were significant differences between the cases and controls in all developmental domains. Cases scored lower in language functioning (mean [M] = 6.5, standard deviation [SD] = 4.3 vs. M = 8.9, SD = 4.6; p < .001); psychomotor functioning (Mdn = 23, interquartile range [IQR] = 17-34 vs. Mdn = 31.0, IQR = 22.0-44.0; Mann-Whitney U = 4,122, p = .002); and socio-emotional functioning ([Mdn = 30.0, IQR = 27.0-33.0 vs. Mdn = 34.0, IQR = 30.0-37.0], Mann-Whitney U = 4,289, p < .001). There was no evidence of association between sepsis and psychomotor (rpb = -.2, p = .214), language (rpb = -.1, p = .510), and socio-emotional functioning (rpb = .0, p = .916). Significant and medium to large portions of the variance (34-64%) in the developmental outcomes among children who survived NNJ were associated with home birth, low maternal education, and feeding problems during the first days of life. CONCLUSIONS: NNJ is associated with developmental impairments in the early childhood years; however, NNJ associated with sepsis does not lead to more severe impairment. Prenatal and postnatal care services are needed to reduce the negative impact of NNJ for children from low resourced settings.

RESUMO

Little is known about resilience after paediatric stroke (PS), or the factors that contribute to better outcomes. Rather, research emphasis has been on impairment, measured through cross-sectional or retrospective designs, often heavily weighted to children presenting for clinical or rehabilitation follow-up. Implementing a resilience framework, this study aimed to investigate cognitive recovery post-stroke and factors that contribute to cognitive resilience at 12 months following PS. In a single site, prospective, longitudinal study (baseline, 1, 6, 12 months post-stroke), 61 children (55.7% male) aged 0-18 years, with a diagnosis of acute arterial ischemic stroke were recruited. Neurological status, lesion and child characteristics were collected at diagnosis. Cognitive, language and motor skills were assessed directly using age-appropriate, standardised tools. Parents rated their mental health, and child social and adaptive abilities. Participants were classified as 'resilient' (74%) or 'vulnerable' based on 12-month cognitive scores. The resilient group demonstrated more intact acute neurological status and higher language and adaptive abilities 1-month post-stroke; 88% of the vulnerable group had strokes involving both cortical and subcortical regions. Neonatal stroke, large lesions, cortical-only lesions, and middle cerebral artery involvement were associated with poorer cognition over the 12 months post-stroke. Absence of seizures and older age at stroke predicted better cognitive outcomes. In summary, most children surviving PS are cognitively resilient at 12 months post-insult. Risk and protective factors identified may guide targeted clinical intervention for more vulnerable children. Future research is needed to explore cognitive resilience trajectories beyond 12 months post-stroke.

RESUMO

OBJECTIVE: The study evaluated the efficacy of phototherapy and 20% albumin infusion to reduce total serum bilirubin (TSB) in neonates with severe hyperbilirubinemia. The primary outcome was a reduction of TSB at the end of treatment. The secondary outcomes were the need for exchange transfusion, inpatient mortality, neurological outcomes at discharge, and development outcomes at 12-months follow-up. RESULTS: One hundred and eighteen neonates were randomly assigned to phototherapy and 20% albumin (n = 59) and phototherapy and saline (n = 69). The median age at admission was 5 (interquartile range (IQR) 3-6) days, and the median gestation was 36 (IQR 36-38) weeks. No significant differences were found in the change in TSB (Mann-Whitney U =609, p = 0.98) and rate of change in TSB per hour after treatment (Mann-Whitney U = 540, p = 0.39) between the two groups. There were no significant differences between the two groups in the proportion of participants who required exchange transfusion (χ2 (2) = 0.36, p = 0.546); repeat phototherapy (χ2 (2) = 2.37, p = 0.123); and those who died (χ2 (2) = 0.92, p = 0.337). Trial registration The trial was registered in the International Standardized Randomized Controlled Trial Number (ISRCTN); trial registration number ISRCTN89732754.

RESUMO

BACKGROUND: CADENCE-BZ is a multi-centre, parallel-group, double-blind randomized controlled trial designed to examine the clinical efficacy and safety of an accessible food preservative, sodium benzoate, as an add-on treatment for patients with early psychosis. The original study protocol was published in 2017. Here, we describe the updated protocol along with the Statistical Analysis Plan (SAP) for the CADENCE-BZ trial prior to study completion. METHODS AND MATERIALS: Two important changes were made to the original protocol: (1) improvements to our statistical analysis plan permitted a reduction in sample size; and (2) a revision in the secondary outcomes with the intent of reducing redundancy and excluding those measures that were not appropriate as outcomes. CONCLUSIONS: We provide the updated SAP prior to the completion of the study with the intent of increasing the transparency of the data analyses for CADENCE-BZ. The final participants are currently completing the study and the results will be published in the near future.

RESUMO

AIM: To describe 5-year motor and functional outcomes after paediatric arterial ischaemic stroke (AIS) and to explore factors associated with poorer long-term outcome. METHOD: Thirty-three children (21 males, 12 females) with AIS were recruited to a single-site, cross-sectional study, from a previously reported prospective longitudinal stroke outcome study. Children were stratified according to age at diagnosis: neonates (≤30d), preschool (>30d-5y), and school age (≥5y). Motor and functional outcomes were measured at 5 years after stroke. Neurological outcomes were evaluated using the Pediatric Stroke Outcome Measure (PSOM) at 1 month and more than 4 years after stroke. RESULTS: At 5 years after stroke, motor function, quality of life, fatigue, adaptive behaviour, activities of daily living, and handwriting speed were significantly poorer than age expectations. The preschool group had the highest percentage of fine and gross motor impairment. Poorer fine motor skills were associated with subcortical-only lesions and large lesion size. Poorer gross motor outcomes correlated with preschool age, bilateral lesions, and PSOM impairment at 1 month. INTERPRETATION: Children are at elevated risk for motor and functional impairments after AIS, with the preschool age group most vulnerable. Identifying early predictors of poorer outcomes facilitates targeted early intervention and long-term rehabilitation. WHAT THIS PAPER ADDS: Following paediatric stroke, children are at elevated risk of motor and functional difficulties. Stroke occurring between 30 days and 5 years of age may result in poorer motor and functional outcomes.

RESUMO

BACKGROUND: Incidence of paediatric stroke has been estimated to range from 1.2 to 13 per 100,000 children under 18 years of age. It is a significant cause of long-term morbidity in children with long-term impacts on physical, cognitive, psychological, and social outcomes. However, little is known about the experiences of parents caring for a child with stroke. Such information is needed to inform the development of child- and family-centred care. METHODS: We conducted in-depth interviews with parents of children with stroke. Participants were purposively sampled from three regional specialist services in England, based on the age of the child at stroke onset and time since first stroke. Interviews used a topic guide and were audio recorded and transcribed in full. Thematic analysis was conducted to develop an account that reflected patients' experiences from their own perspectives. RESULTS: Twelve parents participated with five children classified as having no to mild deficits and seven with moderate to severe deficits. Parents were concerned about the effects of stroke on the child's psychological, cognitive, and social well-being. Significant impacts on parents own well-being and on the family were reported. Although most experienced good quality acute care, meeting the child's needs after hospital discharge was problematic, with low levels of awareness of paediatric stroke among professionals and difficulties accessing relevant information and services. Meeting special education needs was variable. Parents were proactive in seeking to establish a sense of normality for the child and themselves. CONCLUSIONS: The findings illuminate a wider picture of paediatric stroke than indicated by clinical outcomes alone. Parents' experiences varied according to the child's needs but also family's situation and geographical location. Particular attention should be paid to co-ordinating services to meet multiple needs after discharge from hospital.

RESUMO

BACKGROUND: Pediatric stroke has the potential for long term impact on the lives of children and their families. Child-centred intervention depends on understanding of needs from diagnosis onwards. However, little is known about the health and care support self-reported needs of this population. AIMS: This study aimed to describe the nature and extent of needs (met and unmet) of pediatric stroke patients and their families and compare these with previously reported adult stroke needs. METHODS: The questionnaire, adapted from a previously published adult stroke study, was conducted with parents of children who had an ischemic or haemorrhagic stroke between birth - 18 years, and young people with stroke now aged between 12 and 18 years. Participants were recruited from three tertiary pediatric stroke clinics in England. Levels and type of needs, and self-reported neurological impairment were captured. Comparisons of needs was reported descriptively and explored using Chi-square test. RESULTS: Of 44 participants (39 parents, 5 young people), over two thirds reported at least one unmet need. Over half had difficulties in school-related activities, and over one-third in leisure activities and social relationships. Participants reported similar nature and extent of need when compared to previously reported adult stroke needs. Higher severity of neurological impairment was associated with higher number of needs. CONCLUSIONS: Children and young people and their parents have high levels of unmet need across a range of health domains in the months and years after pediatric stroke. This information supports the importance of a needs-based approach to maximising health and well-being.

RESUMO

BACKGROUND: Federal summer meals programs serve less than one-sixth of children that receive free or reduced-price meals during the school year. To address this gap in food assistance for school-aged children, the Summer Electronic Benefits Transfer for Children (SEBTC) Demonstrations provided summer food assistance in the form of electronic benefits transfer cards to households with school-aged children certified for free or reduced-price meals during the school year. METHODS: Over 2011-2013, the SEBTC demonstrations were evaluated by using a random assignment design. Households were randomly assigned a monthly $60-per-child benefit, a monthly $30-per-child benefit, or no benefit, depending on the study year. Key outcomes included children's food security and consumption of foods and food groups related to a healthful diet (diet quality). At baseline (in the spring) and again in the summer, the evaluation surveyed ∼52 000 households over the course of the 3 years of the impact study. RESULTS: SEBTC reduced the prevalence of very low food security among children by one-third. It also had positive impacts on 6 of the 8 child nutrition outcomes measured (amounts of fruits and vegetables; whole grains; dairy foods; and added sugars). CONCLUSIONS: SEBTC is a promising model to improve food security and the dietary quality of low-income school-aged children in the summer months.

RESUMO

Pediatric stroke can result in long-term neurobehavioral impairments including cognitive, language, and motor deficits, all of which may disrupt the normal development of social skills. This study aimed to examine specific components of social function at 5-year poststroke at a group and individual level and explore the contribution of neurobehavioral impairment. Thirty-one children with arterial ischemic stroke participated in the study. Assessment included parent-rated questionnaires measuring social adjustment and social participation as well as behavior and fatigue. Children underwent testing of social cognition and neurobehavioral abilities (intellectual function, attention, pragmatic language, motor function, and neurological impairment). Group means for social function were generally within the normal range, with social adjustment poorer than normative expectations. Examination of impairment rates showed a significant proportion of children had impaired function across social domains. Childhood stroke was associated with poorer social adjustment and a range of neurobehavioral outcomes, compared to neonatal stroke. Social function was found to be impacted by fatigue and intellectual function, but not by attention, pragmatic language, behavior, motor function, or neurological impairment.

RESUMO

OBJECTIVE: To evaluate the relationship between neurologic outcome at 1 month following diagnosis of pediatric arterial ischemic stroke (AIS) and motor and adaptive behavior outcomes at 12 months. METHODS: This prospective longitudinal observational cohort study recruited children from a single tertiary children's hospital diagnosed with first AIS between December 2007 and November 2013. Neurologic impairment was evaluated at 4 time points using the Pediatric Stroke Outcome Measure (PSOM) or Recovery and Recurrence Questionnaire following diagnosis of AIS (acute, 1, 6, and 12 months). Motor function and adaptive behavior were assessed at 12 months using standardized measures. Children were grouped for analysis, according to age at diagnosis (neonates vs preschool vs school-aged). The relationship between neurologic impairment and 12-month functional outcomes were examined. RESULTS: Sixty-four children were recruited (27 neonates, 19 preschool-aged, and 18 school-aged). Presence of impairment on the PSOM at 1 month was associated with lower 12-month fine motor z scores (p = 0.004), gross motor z scores (p = 0.001), and adaptive behavior standard scores (p = 0.004). One-month PSOM impairment score was more predictive than age group or lesion size of 12-month motor and adaptive behavior outcome. CONCLUSIONS: The PSOM has value as a predictive tool when used at 1 month after first AIS diagnosed acutely in relation to motor and adaptive behavior, with variation according to age group.
