Young Children’s cliques : a study on processes of peer acceptance and cliques aggregation

A considerable amount of research has examined the link between children’s peer acceptance, which refers to the degree of likability within the peer group, social functioning and emotional wellbeing, at a same age and in a long term perspective, pointing out to the contribution of peer acceptance for mental wellbeing. Our study proposes a sociometric methodology that, differently from many studies focused on individual classifications of social status, moves to the analysis of affiliative social networks within the class group. This study describes how individual factors such as socio-emotional competence, temperament, and linguistic skills are related to positive reciprocated nominations (=RNs) and examines the cliques generated by reciprocal nominations according to similarities (socio-emotional competence, temperament and linguistic skills) among cliques’ members. Eighty-four preschool children (M age = 62.5 months) were recruited. The Sociometric Interview to assess RNs and the Peabody Picture Vocabulary Test - Revised (PPVT-R; Dunn & Dunn, 1981) to assess receptive language were administered; the Social Competence and Behaviour Evaluation Short Form questionnaire (SCBE-30; LaFreniere & Dumas, 1996) and the Quit Temperament Scale (Axia, 2002) were filled in by the teachers. Results showed that children with higher RNs presented higher scores in social orientation, positive emotionality, motor activity, linguistic skills and social competence (trend), and exhibited lower anxietywithdrawal. The analysis of cliques revealed that children preferred playmates with similar features: social competence, anger-aggression (trend), social orientation, positive emotionality, inhibition to novelty, attention, motor activity (trend) and linguistic skills. These findings provide insights about processes of peer affiliation, highlighting the role of socio-emotional functioning and linguistic skills.peer-reviewe

Predischarge cerebral oxygenation and psychomotor outcome in very preterm infants: is there an association?

This observational study aimed to investigate whether predischarge cerebral oxygenation (CrSO2), monitored by near-infrared spectroscopy, correlates with later psychomotor outcome in very preterm infants. Infants <32 weeks' gestation or <1500 g without evidence of major brain lesions underwent a 3-h continuous CrSO2 monitoring before hospital discharge. Psychomotor development was assessed at 6, 12, 18, and 24 months using the Griffiths Mental Developmental Scales. The developmental quotients (DQ) at each follow-up appointment were correlated with predischarge CrSO2. Significant correlations were adjusted for possible confounders. Sixty-three infants were enrolled. A significant correlation between CrSO2 and DQ was observed at 6 months ca (p=0.010), but not at later psychomotor assessments. This correlation was confirmed significant (b=0.274, p=0.038) even after the adjustment for relevant covariates.Conclusion: According to these preliminary findings, the association between predischarge CrSO2 and psychomotor development over the first 24 months in preterm infants without major brain lesions is time-limited. Hence, this parameter may not represent an effective predictor for medium-term neurodevelopment

Promoting the integration of technology in teaching: An analysis of the factors that increase the intention to use technologies among Italian teachers

AbstractBackground: The rapid spread of COVID‐19 forced many countries to adopt severe containment measures, transferring all didactic activities into virtual environments. However, the integration of technology in teaching may present difficulties, especially in some countries, such as Italy. Objectives: The present study analyzed how the two main factors of the Technology Acceptance Model (TAM), namely perceived usefulness and perceived ease of use, combined with online teaching self‐efficacy, were associated with the intention to use technology to teach. We posited a moderated moderation model in which perceived usefulness represented the main predictor, with self‐efficacy and perceived ease of use as moderators of intention to use technology to teach. Method: The model was tested through multiple regressions, using the PROCESS macro on SPSS 26 with a sample of 178 upper secondary school teachers in Italy. Results and conclusions: Regressions showed that each variable significantly predicted the intention to use technology. In addition, a moderation effect of self‐efficacy on the perceived usefulness of using technology was found for medium and high‐level of perceived ease of use of technology. Implications: The present study provides targeted implications for distance education policy and practice to promote its adoption (or the blended modality) in Italian upper schools

Early-life gut microbiota and neurodevelopment in preterm infants: a narrative review

Infants born preterm are at a high risk of both gut microbiota (GM) dysbiosis and neurodevelopmental impairment. While the link between early dysbiosis and short-term clinical outcomes is well established, the relationship with longterm infant health has only recently gained interest. Notably, there is a significant overlap in the developmental windows of GM and the nervous system in early life. The connection between GM and neurodevelopment was first described in animal models, but over the last decade a growing body of research has also identified GM features as one of the potential mediators for human neurodevelopmental and neuropsychiatric disorders. In this narrative review, we provide an overview of the developing GM in early life and its prospective relationship with neurodevelopment, with a focus on preterm infants. Animal models have provided evidence for emerging pathways linking early-life GM with brain development. Furthermore, a relationship between both dynamic patterns and static features of the GM during preterm infants’ early life and brain maturation, as well as neurodevelopmental outcomes in early childhood, was documented. Future human studies in larger cohorts, integrated with studies on animal models, may provide additional evidence and help to identify predictive biomarkers and potential therapeutic targets for healthy neurodevelopment in preterm infants

Does early object exploration support gesture and language development in extremely preterm infants and full-term infants?

Background: An increasing body of research on typically and atypically developing infants has shown that motor skills play an important role in language development. To date, however, the role of specific object exploration skills for early gesture and vocabulary development has not been investigated in extremely low gestational age infants (ELGA, GA < 28 weeks), who are at greater risk for motor and language delays than full-term (FT) infants. Purpose: This longitudinal study examined relations between 6-month active exploratory behaviors and 12- month word comprehension, gestures and vocal production, controlling for cognitive performance and neonatal condition (ELGA vs FT). Methods: Forty infants, 20 ELGA and 20 FT, and their mothers participated in the study. Mother-infant play interaction was video-recorded at 6 and 12 months. Oral and manual object exploration at 6 months and spontaneous gestures and vocal production at 12 months were coded. Word comprehension was evaluated with the Italian version of the MacArthur-Bates CDI parent questionnaire at 12 months. Cognitive performance was examined with the Griffiths Mental Developmental Scales at 6 months and the Bayley-III Scales at 12 months. Results: Regression analyses showed that after accounting for cognitive performance and neonatal condition, oral exploration was related to word comprehension, and manual exploration to gestures and vocal production in the overall sample. Conclusions: Cascading effects of specific object exploration skills on gestures and language comprehension and production in preterm infants and FT infants are discussed. Clinical implications for early assessment of and interventions involving object exploration skills, which may affect language development, are considered for the preterm population

The Brave study: promoting active breaks in secondary school from students’ point of view

Background: According to the WHO recommendations, children and adolescents should perform at least 60 minutes per day of moderate to vigorous physical activity (PA). Active Breaks (ABs) interventions, short physical activity breaks of 5- 15 minutes during school hours, have been examined in primary school children as a potential strategy to counteract a sedentary lifestyle, with minimal disruption to school learning activities. The aim of the BRAVE STUDY is to investigate the feasibility of ABs in a secondary school setting from the students’ point of view. Methods: In December 2020, 10 students (age 12-13, 6 females and 4 males) attending the second and third grade of secondary schools located in Bologna province (Italy) were involved in a focus group (FG). The FG was conducted online because of COVID-19 and the answers transcribed for a later analysis. Students’ opinions were probed on the role of PA in school and possible facilitators/barriers to implementation of ABs in the school. Results: Students reported they wanted to be more active as a consequence of time spent in class sitting at a desk. Students also reported that an organized activity like ABs conducted in the classroom setting provides an excellent opportunity to improve social relations with classmates. Students also highlighted the possible psycho-physical well-being benefits arising from PA. Among the potentially negative aspects reported, students underlined the possible confusion that would be created in classroom and the time subtracted from academic learning activities. Conclusions: The FG represents an ideal mean to obtain in-depth information on how people feel about a pending program or a change in their routine. The current FG reinforces positive outcomes from exposure to a PA program that can be intertwined with their daily classroom activities. ABs programs can help to reconcile the needs of students that arise during the day with the PA objectives recommended by the WHO. Key messages: ABs can be a zero-cost intervention strategy to achieve WHO recommendations and would create conditions for a greater psycho-physical benefits in classrooms. A qualitative approach, such as FGs, provides a mean to collect information not obtainable with quantitative methods, that could be useful to co-design interventions for children and adolescents

Describing communication profiles of low-risk preterm and full-term late talkers

Introduction: Late talkers represent a heterogeneous population. We aimed to describe communication profiles of low-risk preterm and full-term late talkers according to their receptive and expressive vocabulary size, considering communicative, linguistic, cognitive, and motor skills, as well as biological and environmental risk factors. Methods: Sixty-eight late talkers (33 born low-risk preterm and 35 full-term) were identified through a language screening at 30 months. Parents filled out the Italian Short Forms of the MacArthur Bates Communicative Development Inventories and the Socio Conversational Skills Rating Scales. Children were assessed with the Picture Naming Game test and the Bayley Scales of Infant and Toddler Development. Results: A two-step cluster analysis identified three distinct profiles among late talkers according to their receptive and expressive vocabulary size. Severe late talkers (25%) showed less frequent use of pointing, limited verbal imitation, receptive vocabulary size, lexical and sentence production, responsiveness and assertiveness, and lower cognitive scores than mild late talkers (40%). Moderate late talkers (35%) showed less frequent verbal imitation, limited lexical and sentence production and lower cognitive scores than mild late talkers. Male gender was significantly more represented in the severe late profile, whereas other biological and environmental factors did not differ among the three profiles. Conclusions: Findings highlighted the relevance of assessing communicative, lexical, grammar, pragmatic, and cognitive skills to describe late talkers’ profiles. A deeper investigation of phonological skills might also contribute to a further understanding of interindividual variability in this population

The effect of active breaks on cognitive performance and classroom behaviour: the I-move study

Background: Active Breaks (ABs) intervention involves short bouts of moderate to vigorous physical activity (MVPA) conducted during or between curricular lessons by the appropriately trained teachers. The aim of the Imola Active Breaks Study (IMOVE study) was to evaluate the effect of an ABs intervention on cognitive function and classroom behaviour in primary school children. Methods: The study was quasi-experimental, and it involved two groups attending a primary school in Imola (Bologna, Italy). The Active Breaks group (ABsG) performed the I-MOVE protocol consisting in 10 minutes of ABs divided in warm up, tone-up with high intensity interval training and cool-down. This is repeated three times a day for one year and half. The control group (CG) continued with regular lessons. The baseline assessment was conducted in October 2019 and the follow-up in May 2021. Cognitive performance was assessed using working memory test and classroom behaviour was monitored using an ‘‘ad hoc questionnaire’’. Results: Working memory performance increased significantly more in the ABsG (change: 1.30 1.17) than in CG (0.96 1.20), p &lt; 0.05. Almost the entire sample of the children wanted to continue with this intervention in the next following year. Children reported improvements in their school-life quality, including feeling better in class (75.40%) and in school (82.50%) when using ABs. Improvements were also reported in children time-on-task behaviours: 52.90% said they work easily in class, 52.90% that they could listen more clearly, 58.80% reported they can stay seated easily, and 59.60% that they learned better and were more focused after ABs. Conclusions: In conclusion the program has proven to be very effective on the children’s cognitive improvement and classroom behaviour. Since the ABs intervention demonstrates these positive effects, its implementation in schools can have a beneficial, sustainable and long-term impact on childhood health. Key messages: ABs intervention represents a cost-effective strategy to be implemented in the school settings regardless of the age and sex differences, to make the school a more dynamic environment. Despite the pandemic difficulties, the ABs intervention proved to be sustainable, and to have a positive effect on classroom behaviour by improving children’s concentration and attention in class

The impact of COVID-19 on physical activity behaviour in Italian primary school children: a comparison before and during pandemic considering gender differences

Background: The World Health Organization stated an average of 60 min of Moderate to Vigorous Physical Activity (MVPA) that children should accumulate every day. Nevertheless physical inactivity is growing and, due to restrictions imposed during pandemic, PA levels of children might be more negatively affected. The study aimed to analyse the impact of COVID-19 on the PA of an Italian sample of primary school children by comparing it before and during COVID-19 considering gender differences. Methods: A pre-post analysis (October 2019–January 2021) was conducted using a randomized sample (N = 77) from the I-MOVE study settled in an Italian primary school. Both objective (Actigraph accelerometers) and selfreported (PAQ-c questionnaires) assessments of PA were performed. Changes were compared using T-Student and Chi-Square test. Gender differences were calculated using Anova. Results: Weekly and daily minutes time spent in MVPA significantly decreased respectively by − 30.59 ± 120.87 and − 15.32 ± 16.21 from before to during pandemic while the weekly time spent in sedentary behaviour increased (+ 1196.01 ± 381.49). PAQ-c scores followed the same negative trend (− 0.87 ± 0.72). Boys seem to have suffered more than girls from the imposed restrictions. Conclusion: These findings outline the need for strategies to promote PA and reduce sedentary behaviours in children to prevent COVID-19 restriction long-term effects

Neurodevelopmental Correlates of Brain Magnetic Resonance Imaging Abnormalities in Extremely Low-birth-weight Infants

Objective: To evaluate the relationship between impaired brain growth and structural brain abnormalities at term-equivalent age (TEA) and neurodevelopment in extremely low-birth-weight (ELBW) infants over the first 2&nbsp;years. Methods: ELBW infants born from 2009 through 2018 and undergoing brain magnetic resonance imaging (MRI) at TEA were enrolled in this retrospective cohort study. MRI scans were reviewed using a validated quali-quantitative score, including several white and gray matter items. Neurodevelopment was assessed at 6, 12, 18, and 24&nbsp;months using the Griffiths scales. The independent associations between MRI subscores and the trajectories of general and specific neurodevelopmental functions were analyzed by generalized estimating equations. Results: One hundred-nine ELBW infants were included. White matter volume reduction and delayed myelination were associated with worse general development (b = -2.33, P&nbsp;=&nbsp;.040; b = -6.88, P&nbsp;=&nbsp;.049 respectively), social skills (b = -3.13, P&nbsp;=&nbsp;.019; b = -4.79, P&nbsp;=&nbsp;.049), and eye-hand coordination (b = -3.48, P&nbsp;=&nbsp;.009; b = -7.21, P&nbsp;=&nbsp;.045). Cystic white matter lesions were associated with poorer motor outcomes (b = -4.99, P&nbsp;=&nbsp;.027), while white matter signal abnormalities and corpus callosum thinning were associated with worse nonverbal cognitive performances (b = -6.42, P&nbsp;=&nbsp;.010; b = -6.72, P&nbsp;=&nbsp;.021, respectively). Deep gray matter volume reduction correlated with worse developmental trajectories. Conclusions: Distinctive MRI abnormalities correlate with specific later developmental skills. This finding may suggest that TEA brain MRI may assist with neurodevelopmental prediction, counseling of families, and development of targeted supportive interventions to improve neurodevelopment in ELBW neonates
