Developmental learning disorders in children with prenatal/perinatal exposure to hypoxia: A systematic review protocol

Background Developmental learning disorder (DLD) belongs to neurodevelopmental disorders because it results from the developmental neurodiversity of the brain. The main causes of DLD are genetics, but environmental factors, like inadequate supply of oxygen during pregnancy or labor, are considered. Methods Our search strategy will consist of electronic databases (PubMed, PsycINFO, Web of Science, EMBASE, and Cochrane Library) and hand searching. The observational studies including cohort and case-control studies will be included. The primary outcome will be (DLD). Screening and eligibility will be done independently by two reviewers based on pre-specified eligibility criteria. Data extraction will be based on a pre-pilot data extraction form, and conducted by two authors independently. Study quality will be assessed by two authors independently. Any discrepancies identified at any stage of the review will be resolved by discussion or/and consultation with another reviewer. We plan a narrative and tabular summary of the findings. Discussion This systematic review of aetiology follows the traditional approach to evidence-based healthcare. This secondary research will assess the association between hypoxia and DLD by assessing the relationship of health-related event and outcome and examining the association between them. This review can provide information for healthcare professionals and policymakers indicating whether taking into account information about hypoxia should be permanently included in the diagnostic ontogenetic interview in the process of diagnosing neurodevelopmental disorders.publishedVersio

Internalization of athletic body ideal as a mediating variable between family influence and body image of young women : a cross-cultural study of polish, Italian, and Ukrainian women

Introduction: Our aim was to analyze the strength of the family’s influence on the internalization of the ideal of an athletic figure and, consequently, on the multifactorial image of the body, from the perspective of intercultural differences. Methods: A total of 488 healthy women aged 19–26; of Polish (154), Ukrainian (228), and Italian (106) took part in the study. The Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ-4) and the Multidimensional Body Self Relations Questionnaire (MBSRQ 69) were used to measure athletic ideal internalization and family pressure. The body image of Ukrainian, Polish, and Italian women depends both on the degree of internalization the ideal of an athletic figure and influence of the family. Results and Discussion: The research also suggests significant differences between the three populations, which may suggest cultural differences between young women living in Eastern, Central, and South European countries

Sociocultural predictors of obligatory exercise in young men: A Polish-Chinese comparison

BackgroundObligatory exercise has been shown to have negative physical and mental effects on exercisers and is more prevalent among young people. However, there is limited research on obligatory exercise among young men. Social comparison theory offers a novel perspective to explore the relationship between sociocultural factors and obligatory exercise among young men, which offers an opportunity to understand potential factors contributing to obligatory exercise among young men across different cultures.MethodWe recruited a purposive sample of young people aged 18-30 from Poland (n=79) and China (n=194). Participants completed self-report measures including the Sociocultural Attitudes Toward Appearance Questionnaire3, Inventory of Physical Activity Objectives, and Obligatory Exercise Questionnaire. In the data analysis stage, we examined the strength of the relationships between the independent variables and the dependent variable through multiple regression analysis, and tested the role of the mediating variables.ResultsThe main analyses revealed that Internalization-Athlete was a common direct predictor of obligatory exercise for both Polish and Chinese young men; that there were direct sociocultural predictors of obligatory exercise that were only used in relation to Polish or Chinese young men; and that social adaptation goals for motivation for physical activity mediated the development of obligatory exercise for Polish and Chinese young men, and that there were cross-cultural differences.ConclusionAttention should be paid to their attitudes towards the idea of a muscular and athletic body and socially adapted physical activity motivations when understanding young men’s obligatory exercise, while also considering cross-cultural differences

Generation of Large-Scale Vorticity in a Homogeneous Turbulence with a Mean Velocity Shear

An effect of a mean velocity shear on a turbulence and on the effective force which is determined by the gradient of Reynolds stresses is studied. Generation of a mean vorticity in a homogeneous incompressible turbulent flow with an imposed mean velocity shear due to an excitation of a large-scale instability is found. The instability is caused by a combined effect of the large-scale shear motions (''skew-induced" deflection of equilibrium mean vorticity) and ''Reynolds stress-induced" generation of perturbations of mean vorticity. Spatial characteristics, such as the minimum size of the growing perturbations and the size of perturbations with the maximum growth rate, are determined. This instability and the dynamics of the mean vorticity are associated with the Prandtl's turbulent secondary flows. This instability is similar to the mean-field magnetic dynamo instability. Astrophysical applications of the obtained results are discussed.Comment: 8 pages, 3 figures, REVTEX4, submitted to Phys. Rev.

Heterogeneity of Cognitive Profiles in Children and Adolescents with Mild Intellectual Disability (MID)

Mild Intellectual Disability (MID) is a neurodevelopmental disorder that begins in childhood and is characterized by limitations in intellectual functioning (IQ = 55–69) and adaptive behavior that manifests in everyday living. In addition to these specific criteria, clinical practice shows that the population of children with MID has heterogeneous deficits in cognitive functioning. Thus, the aim of this study was to identify groups of homogenous cognitive profiles within a heterogeneous population of students with MID. The cognitive profiles of 16,411 participants with Mild Intellectual Disability were assessed based on their performance on the Stanford–Binet Intelligence Scales–Fifth Edition. Prior to the assessment, participants were divided into three age groups corresponding to the levels of the Polish education system: (1) 7;00–9;11, (2) 10;00–14;11, and (3) 15;00–18;11 years old. Using cluster analysis, we identified three distinct cognitive profiles (clusters) in each age group. These clusters differed from each other within and between each age group. Distinguishing cognitive profiles among children and adolescents with MID is important both in the context of diagnosis as well as the development of research-based interventions for these students

The main aims of this study were to determine which sociocultural predictors of obligatory exercise are universal for young men or women and which are specific to particular cultural conditions (Polish or Chinese culture) and to examine the mediating role of eating attitudes. A cross-sectional study was conducted among Poles (n = 259) and Chinese (n = 208) aged 18 to 30. Descriptive and comparative statistics, Spearman’s rho, and multiple regression analysis were used. The main analyses showed that Internalization-Athlete was a common positive direct predictor of obligatory exercise among young Polish and Chinese women; Information and Internalization-Athlete were only specific direct positive predictors of obligatory exercise in young Chinese men; some variables in eating attitudes mediated the development of obligatory exercise in young Polish and Chinese men and women and indicated that there were cross-cultural differences. In understanding obligatory exercise among young people, attention should be paid to their sociocultural attitudes toward the body and eating, and cultural and gender differences need to be considered

Socio-cultural attitudes toward the body as a predictor of motivation for physical activity in young people brought up in Asian and European culture—Chinese-Polish comparison

Abstract The influence of sociocultural attitudes toward the body on young people’s physical activity has received increasing attention. However, there is a lack of cross-cultural research in this area. The main aim of this research was to identify the similarities and differences in the sociocultural attitudes toward the body of Polish and Chinese young people who grew up in European and Asian cultures and to analyze their effect on the motivation for physical activity. A cross-sectional research study was conducted among 18- to 30-year-old Polish (n = 259) and Chinese (n = 208) young people. The variables were measured using the Sociocultural Attitudes towards Appearance Questionnaire 3 (SATAQ 3) and the Inventory of Physical Activity Objectives (IPAO). Descriptive and comparative statistics, Spearman’s rho, and the stepwise multiple regression analysis were used. The main analysis showed There are both similarities and significant differences in the performance of young Polish and Chinese men and women on the variables studied; Internalization-Athlete, Pressures, and Internalization-General are universal sociocultural predictors of motivation for physical activity among young people in Poland and China; Information is a specific sociocultural predictor of motivation for physical activity in Polish young people. The cultural nuances need to be considered in understanding young people’s Motivation for undertaking physical activity
