RESUMEN
INTRODUCTION: Early adolescents who are new to Canada experience dual challenges of navigating developmental changes and multiple cultures. This study examined how changes in early adolescents' emotional health from ages 9 to 12 differed by immigration background, and to what extent peer belonging and supportive school climate protected or promoted their emotional health. METHODS: This study drew upon linked self-report and administrative data. Across 10 school districts in British Columbia, Canada, N = 4479 non-immigrant, immigrant, and refugee adolescents reported on their peer belonging, school climate, and emotional health (life satisfaction, optimism, self-esteem, sadness, worries) in Grades 4 and 7, using the Middle Years Development Instrument. Immigration background including immigration class (economic, family, refugee) and generation status (first, second) were obtained from linked Immigration, Refugees, and Citizenship Canada data. Multi-level modeling assessed the effect of time (grade level), immigration group, and changes in peer belonging and school climate on changes in self-reported emotional health. Analyses were adjusted for gender, English first language, and low family income. RESULTS: Immigrant and refugee adolescents reported worse emotional health in Grade 4 compared to non-immigrants. Non-immigrant and immigrant adolescents reported declines in emotional health from Grades 4 to 7. In contrast, first-generation refugee adolescents reported significant improvements in life satisfaction, and first- and second-generation refugees reported improvements in worries over this period. Perceived improvements in peer belonging and school climate were associated with positive changes in emotional health for all adolescents. CONCLUSIONS: Changes in adolescents' emotional health from Grades 4 to 7 differed between immigrants, refugees, and non-immigrants. Immigrants and refugees who enter adolescence with lower emotional health than their non-immigrant peers may particularly benefit from culturally responsive school and community-based interventions.
RESUMEN
Because healthy psychosocial development in the first years of life is critical to lifelong well-being, governmental, and nongovernmental organizations are increasingly interested in monitoring psychosocial behaviors among populations of children. In response, the World Health Organization is developing the Global Scales of Early Development Psychosocial Form (GSED PF) to facilitate population-level psychosocial monitoring. Once validated, the GSED PF will be an open-access, caregiver-reported measure of children's psychosocial behaviors that is appropriate for infants and young children. This study examines the psychometric validity evidence from 45 items under consideration for inclusion in the GSED PF. Using data from N = 836 Nebraskan (USA) children aged 180 days to 71 months, results indicate that scores from 44 of the 45 (98%) items exhibit positive evidence of validity and reliability. A bifactor model with one general factor and five specific factors best fit the data, exhibited strong reliability, and acceptable model fit. Criterion associations with known predictors of children's psychosocial behaviors were in the expected direction. These findings suggest that measurement of children's psychosocial behaviors may be feasible, at least in the United States. Data from more culturally and linguistically diverse settings is needed to assess these items for global monitoring.
Debido a que el desarrollo sicosocial en los primeros años de vida es crítico para el bienestar de toda la vida, las organizaciones gubernamentales y no gubernamentales están más y más interesadas en observar vigilantemente las conductas sicosociales en la población infantil. Como respuesta, la Organización Mundial de la Salud está desarrollando el Formulario Sicosocial de las Escalas Globales del Temprano Desarrollo (GSED PF) para facilitar la observación sicosocial alerta al nivel del grupo de población. Una vez que se haya convalidado, el GSED PF será una medida de acceso abierto, que reportará el cuidador, sobre las conductas sicosociales de los niños que son apropiadas para infantes y niños pequeñitos. Este estudio examina la evidencia de la validez sicométrica de 45 puntos bajo consideración para ser incluidos en el GSED PF. Usando datos de N = 836 niños de Nebraska (Estados Unidos), de edad entre 180 días y 71 meses, los resultados indican que los puntajes de 44 de los 45 (98%) puntos muestran evidencia positiva de validez y confiabilidad. Un modelo bifactorial con un factor general y cinco factores específicos, que mejor encaja con los datos, mostró una fuerte confiabilidad y un modelo aceptable que encaja. Las asociaciones de criterio con factores de predicción conocidos acerca de las conductas sicosociales de los niños se encontraban en la dirección esperada. Estos resultados sugieren que la medida de las conductas sicosociales de los niños pudiera ser posible, por lo menos en los Estados Unidos. Se necesitan datos de escenarios más diversos cultural y lingüísticamente para evaluar estos puntos para la estar alerta en la observación global.

PURPOSE: Evidence from systematic reviews suggests that adult immigrants living in areas of higher immigrant density (areas with a higher proportion of foreign-born residents) tend to experience fewer mental health problems-likely through less discrimination, greater access to culturally/linguistically appropriate services, and greater social support. Less is known about how such contexts are associated with mental health during childhood-a key period in the onset and development of many mental health challenges. This study examined associations between neighbourhood immigrant density and youth mental health conditions in British Columbia (BC; Canada). METHODS: Census-derived neighbourhood characteristics were linked to medical records for youth present in ten of BC's largest school districts from age 5 through 19 over the study period (1995-2016; n = 138,090). Occurrence of physician assessed diagnoses of mood and/or anxiety disorders, attention deficit hyperactivity disorder (ADHD), and conduct disorder was inferred through International Classification of Diseases (ICD) diagnostic codes in universal public health insurance records. Multi-level logistic regression was used to model associations between neighbourhood characteristics and odds of diagnoses for each condition; models were stratified by generation status (first-generation: foreign-born; second-generation: Canadian-born to a foreign-born parent; non-immigrant). RESULTS: Higher neighbourhood immigrant density was associated with lower odds of disorders among first-generation immigrant youth (e.g., adjusted odds of mood-anxiety disorders for those in neighbourhoods with the highest immigrant density were 0.67 times lower (95% CI: 0.49, 0.92) than those in neighbourhoods with the lowest immigrant density). Such protective associations generally extended to second-generation and non-immigrant youth, but were-for some disorders-stronger for first-generation than second-generation or non-immigrant youth. CONCLUSIONS: Findings suggest there may be protective mechanisms associated with higher neighbourhood immigrant density for mental health conditions in immigrant and non-immigrant youth. It is important that future work examines potential pathways by which contextual factors impact immigrant and non-immigrant youth mental health.

BACKGROUND: Many children born very low birth weight (VLBW) experience school struggles with preparedness requiring adequate physical, social, behavioural, cognitive and communication skills. A global assessment of proficiency is necessary to identify those at risk in any such area and direct early intervention accordingly. Study objectives were to characterize developmental vulnerability and school readiness scores in these key domains in a sample of children born VLBW versus their provincial public school system peers and identify early-life infant and parent factors related to suboptimal school readiness. METHODS: The Early Development Instrument teacher assessments of school readiness were collected for a Canadian VLBW sample (NCT02759809). Comparisons between children born VLBW and peers were made. Group differences between children born VLBW considered vulnerable (<10th percentile, not developmentally ready for learning) and not vulnerable were tested and linear regression explored associations between early-life factors and domain scores. RESULTS: Of 77 available Early Development Instrument assessments, median (interquartile range) assessment age was 6.0 (5.7, 6.2) years, birth weight 950 (793, 1250) grammes and birth gestation 27.4 (25.6, 29.7) weeks. A higher proportion of children born VLBW versus peers exhibited vulnerability in Physical Health and Well-being (24.7% vs. 16.1%, p = 0.04), Communication Skills and General Knowledge (23.4% vs. 10.2%, p = 0.0001) and vulnerability in ≥2 domains (26.0% vs. 14.4%, p = 0.004). Children born VLBW classified as vulnerable versus not vulnerable had lower birth gestation and 5-min Apgar. Adjusted regression models found Apgar <7 associated with lower scores for Physical Health and Well-being (-0.86; 95%CI: -1.71, -0.00; p = 0.049), Social Competence (-1.77; 95%CI: -2.92, -0.62; p = 0.003), Emotional Maturity (-1.55; 95%CI: -2.43, -0.66; p = 0.0009) and Communication Skills and General Knowledge (-1.63; 95%CI: -3.19, -0.06; p = 0.04). CONCLUSIONS: This VLBW sample exhibited poor school readiness in multiple domains. Identification of lower birth gestation and Apgar may assist targeted early interventions to mitigate vulnerability.

Despite anxiety being a prevalent mental health problem in children, little data exist on the pervasiveness and levels of anxiety symptoms in kindergarteners. Data from the Early Development Instrument, a teacher-completed, population-level measure of child development, were collected across Canada from 2004 to 2015. The final analytic sample consisted of 974,319 children of whom 2.6% were classified as "highly anxious". Compared to children who exhibited "few to none" anxious behaviors, highly anxious children were more likely to be male, have English/French as a second language, and have a special needs designation. Furthermore, compared with their less anxious peers, highly anxious children had between 3.5 and 6.1 higher odds of scoring below the 10th percentile cut-off in physical, social, language/cognitive and communication domains. Our findings suggest that anxious behaviors are related to children's overall health and illustrate the consistency and extensiveness of anxiety at a very young age among Canadian children.

When the COVID-19 pandemic was declared in March 2020, the lives of families all over the world were disrupted. Many adults found themselves working from home while their children were unable to go to school. To better understand the potential impact of these educational disruptions, it is important to establish what learning looked like during the first school shutdown in the spring of 2020, particularly for the youngest learners who may feel the longest lasting impacts from this pandemic. Therefore, the purpose of the current descriptive study was to gather information on how kindergarten teaching and learning occurred during this time, what the biggest barriers were, and what concerns educators had regarding returning in person to the classroom setting. The sample for the current study was 2569 kindergarten educators (97.6% female; 74.2% teachers, 25.8% early childhood educators) in Ontario, Canada. Participants completed a questionnaire consisting of both quantitative scales and qualitative open-ended questions. Educators reported that parents most often contacted them regarding technological issues or how to effectively support their child. The largest barrier to learning was the ability of both parents and educators to balance work, home life, and online learning/teaching. With regards to returning to school, educators were most concerned about the lack of ability of kindergarten aged children to do tasks independently and to follow safety protocols. Our findings highlight unique challenges associated with teaching kindergarten during the pandemic, contributing to our understanding of the learning that occurred in Ontario during the first COVID-19 shutdown.

RESUMEN
BACKGROUND: The primary aim of this study was to determine if screen use in early childhood is associated with overall vulnerability in school readiness at ages 4 to 6 years, as measured by the Early Development Instrument (EDI). Secondary aims were to: (1) determine if screen use was associated with individual EDI domains scores, and (2) examine the association between screen use and EDI domains scores among a subgroup of high screen users. METHODS: This prospective cohort study was carried out using data from young children participating in a large primary care practice-based research network in Canada. Logistic regression analyses were run to investigate the association between screen use and overall vulnerability in school readiness. Separate linear regression models examined the relationships between children's daily screen use and each separate continuous EDI domain. RESULTS: A total of 876 Canadian participants participated in this study. Adjusted logistic regression revealed an association between increased screen use and increased vulnerability in school readiness (p = 0.05). Results from adjusted linear regression demonstrated an association between higher screen use and reduced language and cognitive development domain scores (p = 0.004). Among high screen users, adjusted linear regression models revealed associations between increased screen use and reduced language and cognitive development (p = 0.004) and communication skills and general knowledge domain scores (p = 0.042). CONCLUSIONS: Screen use in early childhood is associated with increased vulnerability in developmental readiness for school, with increased risk for poorer language and cognitive development in kindergarten, especially among high users.

BACKGROUND: Refugee children face numerous challenges associated with pre-migration trauma and post-migration adaptation. Much research pertaining to refugee children's well-being focuses on psychiatric symptoms. Relatively few studies have examined how social context factors-such as perceptions of peer belonging, and support from adults at home and at school-contribute to the emotional health of refugee children. Informed by social-ecological theories emphasizing dynamic interactions between the contexts in which children develop, we examined associations between social context factors and emotional health in refugee children. METHODS: Data were drawn from a population-based data linkage in British Columbia, Canada. The analytic sample included 682 grade 4 students (Mage 9.2 years; 46.3% female) with a refugee background who responded to the Middle Years Development Instrument (MDI) during the 2010/2011-2016/2017 school years. The MDI is a self-report survey of children's social and emotional competencies and social context factors completed at school. Regression analyses were used to examine associations of social context factors (school climate, supportive adults at school and at home, and peer belonging) with indicators of emotional health (life satisfaction, self-concept, optimism, and sadness). Refugee generation status (first/second) was considered through stratification and testing of interactions with social context factors. RESULTS: Perceived supportive school climate, support from adults in school and at home, and peer belonging were each independently associated with better emotional health. Results were similar for first- and second-generation children. CONCLUSION: Taken together, results suggest a unique role of the school context to refugee children's emotional health. School-based programming that promotes positive school climate can be considered as an important approach to support newcomer refugee children and their families.

OBJECTIVES: Changes to income and employment are key social determinants of health that have impacted many families during the COVID-19 pandemic. This research aimed to understand how changes to employment and income influenced family environments that contribute to early childhood development and health. METHODS: A concurrent triangulation mixed method design was used through a cross-sectional survey on early impacts of the COVID-19 pandemic involving families with young children in the Canadian Maritime provinces (n = 2158). Analyses included multivariate regression models to examine whether changes to employment and income predicted changes to Family access to resources and social support, parenting Abilities and self-care at home, and home Routines and Environments (FARE Change Scale). Content analysis was used to identify themes from the open-ended questions. RESULTS: Changes to employment and income early in the pandemic like no longer working but continued to receive salary, working fewer hours for the same salary earned before the pandemic, no longer working nor receiving salary, working fewer hours resulting in salary reduction, essential worker status and household income were significant predictors of FARE Change Scale when ethnicity/cultural background and province of residence are controlled (P < .05). Themes provided a description of family impacts, including shifting employment and income, finding time and capacity, feelings of guilt and the creation of new routines. CONCLUSION: Our study provides insight on the implications of public health restrictions, such as the importance of increased time for parents (through reduced work hours) and access to resources and social support to support child development and health.

The present study, conducted during the first wave of the COVID-19 pandemic in Ontario, Canada, addressed the association between family responsibilities and mental health (depression and anxiety) among kindergarten educators. Participants comprised 1790 (97.9% female) kindergarten educators (73.6% kindergarten teachers; 26.4% early childhood educators) across Ontario. Results revealed that educators were more likely to report moderate levels of depressive symptoms if they had the responsibility of caring for their own children, and more likely to report moderate levels of depressive and anxious symptoms if they had the responsibility of caring for an older adult. Theoretical and practical implications are discussed.
RESUMEN
BACKGROUND: Nutrition in early childhood is important for healthy growth and development. Achieving school readiness is considered one of the most important developmental milestones for young children. OBJECTIVES: The purpose of this study is to determine if nutritional risk in early childhood is associated with school readiness in kindergarten. METHODS: A prospective cohort study was conducted through The Applied Research Group for Kids (TARGet Kids!) primary care research network in Toronto, Canada, 2015-2020. Nutritional risk was measured (18 mo to 5 y) using validated parent-completed questionnaires called Nutrition Screening for Toddlers and Preschoolers (NutriSTEP). High nutritional risk was categorized as scores ≥21. School readiness was measured using the validated teacher-completed Early Developmental Instrument (EDI), which measures 5 developmental domains in kindergarten (2 y of schooling, ages 4-6 y, before they enter grade 1). Vulnerability indicates scores lower than a population-based cutoff at the 10th percentile on at least 1 domain. Multiple logistic and linear regression models were conducted adjusting for relevant confounders. RESULTS: The study included 896 children: 53% were male, 9% had high nutritional risk, and 17% were vulnerable on the EDI. A 1-SD increase in NutriSTEP total score was associated with 1.54 times increased odds of being vulnerable on the EDI among children in year 2 of kindergarten (P = 0.001). High nutritional risk cutoff was associated with 4.28 times increased odds of being vulnerable on the EDI among children in year 2 of kindergarten (P < 0.001). NutriSTEP total score and high nutritional risk were associated with lower scores on all 5 EDI domains, with the strongest association observed for the domains of language and cognitive development and communication skills and general knowledge. CONCLUSIONS: Higher nutritional risk in early childhood is associated with lower school readiness in year 2 of kindergarten. Nutritional interventions early in life may offer opportunities to enhance school readiness. This trial was registered www.clinicaltrials.gov as NCT01869530.

OBJECTIVE: To determine if nutritional risk in early childhood is associated with parent-reported school concerns. DESIGN: A prospective cohort study conducted through the TARGet Kids! primary care research network (2011-2018). Nutritional risk was measured between 18 months and 5 years of age using validated parent-completed NutriSTEP® questionnaires with eating behaviour and dietary intake subscores (0 = lowest and 68 = highest total nutritional risk score). Parent-reported school concerns were measured at school age (4-10 years of age) and included: speech and language; learning; attention; behaviour; social relationships; physical coordination; fine motor coordination and self-help skills and independence. The primary outcome was any parent-reported school concerns, and individual school concerns were used as secondary outcomes. Multiple logistic regression models were conducted adjusting for clinically relevant confounders to assess the relationship between nutritional risk and school concerns. SETTING: Toronto, Canada. PARTICIPANTS: Children aged 18 months to 10 years. RESULTS: The study included 3655 children, 52 % were male, mean NutriSTEP® score was 14·4 (sd 6·4). Each 1 sd increase in NutriSTEP® total score was associated with a 1·18 times increased odds of school concerns (adj OR: 1·18, 95 % CI 1·07, 1·28, P = 0·0004), and high nutritional risk was associated with a 1·42 times increased odds of school concerns (adj OR: 1·42, 95 % CI 1·13, 1·78, P = 0·002). CONCLUSIONS: Nutritional risk in early childhood was associated with school concerns. Nutritional interventions in early childhood may reveal opportunities to enhance school outcomes.

BACKGROUND: Positive parenting interventions were traditionally developed for use in infant and preschool mental health. However, there is increasing application to a broader range of developmental outcomes. A scoping review was conducted to map the landscape of the diverse applications of positive parenting interventions to academic school readiness. METHODS: Positive parenting interventions that took place in the early childhood period (prenatal to 6 years) and included an assessment of academic readiness were eligible (i.e., problem-solving/reasoning, language, executive functions and preacademics). The search strategy included four electronic databases from inception to July 2020 and backward/forward searching of the majority of eligible studies. Data charting was completed by double, independent reviewers and included theoretical frameworks, academic readiness outcomes, parenting behaviour targets, populations serviced and methodological approaches used. The synthesis included quantitative descriptives and tabular/visual representations. RESULTS: Ninety-nine studies met eligibility criteria. There has been a steady increase in published studies since 2005, with each academic readiness skill represented in varying proportions. Attachment theory was the most commonly referenced framework for applying interventions to academic readiness, with a more recent shift towards biobehavioural frameworks. The majority of studies included parental responsiveness as a parent behaviour target, whereas behavioural management was more commonly used with older children and/or those with social-emotional/behavioural difficulties. Most studies used a selective prevention approach, with low socioeconomic families being the most frequently studied group. Research gaps were identified in the measurement of follow-up and parenting behaviour. CONCLUSION: We discuss changing conceptualizations of academic readiness, applications to public health and practice, and future directions in research.

Poverty has a well-established association with poor developmental outcomes in children but is often found to be a weak predictor of outcomes for migrant children. Building on theory focused on the developmental competencies of minority children, the current study used a systematic and novel analytic approach to disentangle the relationship between income and developmental outcomes for different groups of migrant children. Utilizing a population-based cohort of children in British Columbia, Canada (Nâ¯=â¯23,154), the study examined whether income differently predicted the kindergarten to Grade 7 (K-7) literacy and numeracy trajectories of migrant children (economic, family, and refugee groups), in comparison to non-migrants. By applying Group-Based Trajectory Modeling (GBTM), the study found that lower income was generally associated with lower K-7 literacy and numeracy achievement trajectories. The relationship between income and achievement did not differ for migrant children in comparison to non-migrant children, with the exception of one sub-group of high-achieving economic class migrant children, which appeared to be less impacted by low income levels. Follow-up binomial logistic regression analysis found that parental education levels at migration and English language ability predicted which migrant children would be high literacy and numeracy achievers despite low income. The results suggest that basic associations between poverty and the outcomes of migrant children mask an underlying complexity: For most migrant children, poverty was just as predictive of detrimental academic outcomes as it was for non-migrant children and being in the exceptional sub-group of high-achieving, low-income migrant children was partly accounted for by other protective factors.
RESUMEN
OBJECTIVES: To compare the reliability and convergent validity of parent assessments from the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID-a structured diagnostic interview) and the Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) symptom checklist for classifying conduct disorder (CD), conduct disorder or oppositional defiant disorder (CD-ODD), attention-deficit hyperactivity disorder (ADHD), major depressive disorder (MDD), generalized anxiety disorder (GAD), and separation anxiety disorder (SAD) based on DSM-5 criteria. METHODS: Data came from 283 parent-youth dyads aged 9 to 18 years. Parents and youth completed the assessments separately on 2 different occasions 7 to 14 days apart. After converting the OCHS-EBS scale scores to binary disorder classifications, we compare test-retest reliability estimates and use structural equation modelling (SEM) to compare estimates of convergent validity for the same disorders assessed by each instrument. RESULTS: Average test-retest reliabilities based on κ were 0.71 (MINI-KID) and 0.67 (OCHS-EBS). The average ß coefficients for 3 latent measures comprising the following indicators-parent perceptions of youth mental health need and impairment, diagnosis of specific disorders based on health professional communications and youth taking prescribed medication, and youth classifications of disorder based on the MINI-KID-were 0.67 (MINI-KID) and 0.69 (OCHS-EBS). CONCLUSION: The OCHS-EBS and MINI-KID achieve comparable levels of reliability and convergent validity for classifying child psychiatric disorder. The flexibility, low cost, and minimal respondent burden of checklists for classifying disorder make them well suited for studying disorder in the general population and screening in clinical settings.

OBJECTIVES: To describe the development and psychometric properties of the 2014 Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) for dimensional measurement of 7 disorders based on criteria from the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). METHODS: Scale items were selected by agreement among 19 child psychologists and psychiatrists rating the correspondence between item descriptions and DSM-5 symptoms. Psychometric evaluation of the item properties and parent/caregiver and youth scales came from a general population study of 10,802 children and youth aged 4 to 17 years in 6537 families. Test-retest reliability data were collected from a subsample of 280 children and their caregivers who independently completed the OCHS-EBS checklist on 2 occasions 7 to 14 days apart. Structural equation modelling was used to assess internal and external convergent and discriminant validity-the latter tested against the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID). RESULTS: Confirmatory factor analyses exhibited adequate item fit to all scales. Except for conduct disorder and youth-assessed separation anxiety disorder, internal (Cronbach's α) and test-retest reliability (Pearson's r) for scale scores were 0.70 or above. Except for youth-assessed conduct disorder, the OCHS-EBS met criteria for internal and convergent and discriminant validity. Compared with the MINI-KID, the OCHS-EBS met criteria for external convergent and discriminant validity. CONCLUSIONS: The OCHS-EBS provide reliable and valid dimensional measurement of 7 DSM-5 disorders assessed by caregivers and youth in the general population. Part II describes use of the OCHS-EBS as a categorical (present/absent) measure of disorder.

BACKGROUND: Dental problems are the most prevalent chronic disease worldwide, with up to half of all kindergarten children having tooth decay. However, there is a lack of evidence of whether unaddressed dental needs (UDNs) are associated with children's developmental health, a concept reflecting holistic child development - encompassing physical, emotional, and cognitive development. The objective of the current study was to evaluate the relationship between UDNs and developmental health among kindergarten children using the Early Development Instrument (EDI). METHODS: We examined associations between teacher reported UDNs and developmental vulnerability on the EDI. Children were included in the study if they were enrolled in kindergarten in publicly-funded schools in Canada between 2010 and 2015, had been in the classroom for at least one month, and had no more than 25% of missing items on the questionnaire. RESULTS: Among 576,264 children who met inclusion criteria (95.4% of eligible children), 2465 (0.4%) were identified as having UDNs by their teachers. Children with UDNs had 4.58 to 8.27 times higher odds of being vulnerable on any of the five developmental domains (physical health and well-being, social competence, emotional maturity, language and cognitive development, communication skills and general knowledge), compared to children without UDNs. CONCLUSION: In this study, teacher-reported UDNs were associated with developmental vulnerability in kindergarten children. Teacher reported unmet dental needs in kindergarten children may be a proxy for poor developmental health at school entry, and thus a marker for supporting both children's oral health and early developmental needs.

AIM: Population-level data on the development of children with special health needs attending primary school can assist special education, health and service delivery strategies. This study aims to determine whether results of the Early Development Instrument (EDI) can be interpreted and used with the same confidence for children with special health needs as for those who are typically developing. Psychometric properties of the EDI for kindergarteners with identified special health needs are examined. METHODS: Data for children with a special health need designation come from a database of all Canadian provincial implementations of the EDI between 2004 and 2014. Item and domain characteristics (distributions of scores and measures of internal consistency) of the EDI were examined. Construct validation was assessed by correlating EDI scores with gender and age. The fit of the original factor structure of the EDI was evaluated using confirmatory factor analysis. RESULTS: Data for 29 692 children (69.8% male) were analysed. The performance of items and domains was similar to that of typically developing children. As expected, boys scored lower on all EDI domains (Cohen's d: 0.03-0.46) and a general, but non-significant, positive trend was observed between age and EDI scores. The factor structure of the EDI in this population yielded similar goodness-of-fit statistics as those reported in studies with typically developing children. CONCLUSION: Results of this investigation support the validity of the EDI in children with special health needs, paving the way for a more extensive use of EDI data for this vulnerable, yet often neglected, population.

The antibacterial activity of concrete plates loaded with various titania photocatalysts was investigated. The target in bacteria testing was Escherichia coli K12. The presence of photocatalysts in the concrete matrix at a dose of 10 wt.% improved the antibacterial properties, which became significant depending on the type of the added photocatalyst. Total inactivation of E. coli irradiated under artificial solar light was observed on the concrete plates loaded with the following photocatalysts: TiO2/N,CMeOH-300, TiO2/N,CEtOH-100, TiO2/N,CisoPrOH-100 and TiO2/N-300. The modified Hom disinfection kinetic model was found as a best-fit model for the obtained results. The presence of nitrogen and carbon in the photocatalysts structure, as well as crystallite size, surface area and porosity, contributed to the increase of antibacterial properties of concrete plates.

BACKGROUND: Upregulation of the immune system is regarded to play an important role in the etiopathobiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). To the best of our knowledge, neopterin (NP) has never been investigated in patients with PAH and CTEPH. OBJECTIVES: The aim of the study was to evaluate the concentration of NP in blood in order to examine its impact on outcome and relationship with disease severity in that population. METHODS: Serum concentration of NP was analysed prospectively in 50 patients (36 with PAH and 14 with CTEPH vs. 31 healthy controls) and assessed in relation to clinical parameters and outcome. RESULTS: NP concentration in the PAH and CTEPH groups combined was significantly higher than in the control group (8.68, 6.39-15.03 vs. 5.14, 4.16-5.98 nmol/L, p < 0.0000001). During 9 months of follow-up, clinical deterioration occurred in 18 patients (including 8 deaths), and NP concentration in this group was higher when compared to stable patients (15.6, 8.52-25.13 vs. 7.87, 6.18-9.89, p = 0.002). The cutoff value of NP derived from ROC curve analysis was 15.3 nmol/L (p = 0.002, AUC 0.77, p = 0.0004, HR = 4.35, 95% CI 1.43-13.18, log-rank test). On Cox regression analysis, NP predicted clinical deterioration (p = 0.009, 95% CI 1.01-1.06). NP correlated positively with NT-proBNP (p < 0.001), red blood cell distribution width (p < 0.001), and right atrium area (p = 0.002) and inversely with 6-min walking test (p = 0.002) and peak oxygen consumption (p = 0.001). CONCLUSIONS: NP concentration is increased in patients with PAH and inoperable CTEPH. Elevated NP concentration is associated with adverse clinical outcomes and correlates with clinical parameters.
