RESUMO
Obesity, a complex disorder with rising global prevalence, is a chronic, inflammatory, and multifactorial disease and it is characterized by excessive adipose tissue accumulation and associated comorbidities. Adipose tissue (AT) is an extremely diverse organ. The composition, structure, and functionality of AT are significantly influenced by characteristics specific to everyone, in addition to the variability connected to various tissue types and its location-related heterogeneity. Recent investigation has shed light on the intricate relationship between bone marrow stem cells and obesity, revealing potential mechanisms that contribute to the development and consequences of this condition. Mesenchymal stem cells within the bone marrow, known for their multipotent differentiation capabilities, play a pivotal role in adipogenesis, the process of fat cell formation. In the context of obesity, alterations in the bone marrow microenvironment may influence the differentiation of mesenchymal stem cells towards adipocytes, impacting overall fat storage and metabolic balance. Moreover, bone marrow's role as a crucial component of the immune system adds another layer of complexity to the obesity-bone marrow interplay. This narrative review summarizes the current research findings on the connection between bone marrow stem cells and obesity, highlighting the multifaceted roles of bone marrow in adipogenesis and inflammation.

INTRODUCTION: It is widely demonstrated that high frequency (HF) repetitive transcranial magnetic stimulation (rTMS) has facilitative effects and is therefore capable to inducing changes in motor responses. One of the most investigated areas is the dorsolateral prefrontal cortex (DLPFC) as it plays a special executive attention role in actively preserving access to stimulus representations and objectives in environments with plenty of distraction such as those of team sports. Volleyball is a team sport in which the attention and coordination components are essential for achieving performance. Thus, the aim of this study was to investigate if HF rTMS at DLPFC in volleyball players can improve homolateral motor coordination and cortical excitability. RESULTS: This study was a double-blinded (participant and evaluator) matched-pair experimental design. Twenty right-handed female volleyball players were recruited for the study and were randomly assigned either the active rTMS (n = 10) or the sham stimulation group (n = 10). The stimulation was performed in one session with 10 Hz, 80% of the resting motor threshold (RMT) of the right first dorsal interosseous muscle, 5 s of stimulation, and 15 s of rest, for a total of 1500 pulses. Before and after stimulation, the coordination and the cortical excitability were evaluated. The significant finding of this paper was that HF-rTMS of the DLPFC improved performance in terms of the homolateral interlimb coordination, with a significantly decreased in resting motor threshold and MEP latency of the ipsilateral motor cortex. It seem that HF-rTMS could increase coordination performances when the velocity of the execution is higher (120 bpm and 180 bpm). CONCLUSION: Moreover, in active rTMS group significant differences emerged after stimulation in RMT and in MEP latency, while no differences emerged after stimulation in MEP amplitude. In conclusion we believe that these results may be of great interest to the scientific community and may also have practical implications in the future.

Homophobic bullying is a major social issue, especially in the school settings. This may be particularly common in many Western countries but it appears globally. Bullying causes both short and long-term problems hence its prevention must be seen as a relevant and urgent step in educational settings. Psycho-educational programs should be promoted in order to help eliminate school-children's prejudices and bias about gay and lesbian peers, homophobic bullying. 191 school-children (n = 101 females, n = 90 males), aged 12-14 years old, attending a secondary school in Foggia (Italy) were recruited and assessed at baseline (T0) and 2 months (T1) after receiving a systematized, repeated psycho-education aimed to promote their awareness on sexual variations, and reduce homophobic prejudices and stereotypes. They were assessed for their empathy quotients, their knowledge of gender- related stereotypes, homophobic attitudes, anger, emotional regulation, before (T0) and after the intervention (T1) in a standardized manner. The psychoeducational program significantly reduced homophobia levels towards gays (-9.38%) and lesbians (-5.42%,) as well as improved emotional adjustment (+25.9%) and pro-sociality (+3.85%) among school-children (0.0486≤ all p < 0.0001). Also, a statistically significant improvement of empathy (+11.3%) and levels of state anger (+0.35%) has been significantly reported. This study reports on the benefits of a repeated, systematic, prospective psycho-educational intervention conducted in the school-setting leading to an improvement of empathy, pro-sociality, emotional regulation and a reduction of homophobic attitudes and anger among students.

BACKGROUND: Morality and moral reasoning develop over the course of life, but such development may encounter obstacles. Psycho-educational interventions could be designed to improve moral reasoning and attitude towards prosociality. In the last decades, many interventions employed digital technologies ranging from multicomponent online platforms to serious games and virtual reality, making use of interactivity and immersive properties that could make moral stimuli more engaging. AIMS: This study aimed at reviewing the literature on digital interventions to support morality and moral reasoning, carried out with subjects of all age groups. METHODS AND RESULTS: Two electronic databases were searched with a systematic approach, and retrieved publications were scanned by authors against inclusion criteria. Twenty-three articles were reviewed. In general, the literature describes encouraging results of digital interventions to support morality. Moreover, a huge variety of morality conceptualizations emerged across various contexts (e.g., professional, school and sports) as well as various outcome measurements (e.g., change in attitudes and change in behaviour). CONCLUSIONS: Effectiveness of digital interventions may relate to immersive and interactive simulations in particular, in that they allow participants not only to learn about moral rules and principles but also to actively exercise their own morality to make decisions. Future research may build on the present scoping review to analyse specific types of interventions' effectiveness with a meta-analytical approach.
RESUMO
Artificial Intelligence (AI) tools are currently designed and tested in many fields to improve humans' ability to make decisions. One of these fields is higher education. For example, AI-based chatbots ("conversational pedagogical agents") could engage in conversations with students in order to provide timely feedback and responses to questions while the learning process is taking place and to collect data to personalize the delivery of course materials. However, many existent tools are able to perform tasks that human professionals (educators, tutors, professors) could perform, just in a timelier manner. While discussing the possible implementation of AI-based tools in our university's educational programs, we reviewed the current literature and identified a number of capabilities that future AI solutions may feature, in order to improve higher education processes, with a focus on distance higher education. Specifically, we suggest that innovative tools could influence the methodologies by which students approach learning; facilitate connections and information attainment beyond course materials; support the communication with the professor; and, draw from motivation theories to foster learning engagement, in a personalized manner. Future research should explore high-level opportunities represented by AI for higher education, including their effects on learning outcomes and the quality of the learning experience as a whole.
RESUMO
This article presents data collected through Computer-Assisted Web Interviewing (CAWI), conducted in Italy with the aim of exploring the Italian population's reaction to the Russian invasion of Ukraine in February 2022 and monitoring this reaction for the first six months of the attack through a six-round survey. Each round involved a representative sample of approximately 1010 (1007-1015) Italian adult citizens. Participants were asked questions about emotional reactions to the Russian invasion, coping strategies used, solidarity behaviour toward Ukrainian refugees, perceptions of refugees as a threat to the country, trust in national and international authorities to manage the international situation, and prospects for the future. Demographic data on the respondents were also collected. The survey design was developed by a research group from two universities (the University of Salento and the University of Foggia) and a European research centre, EICAP (European Institute of Cultural Analysis for Policy). The data provided in this article is a resource for researchers, public authorities, and other parties interested in surveying and studying public opinion. This dataset can be used to explore a wide range of topics, including prosocial behaviour and attitudes towards refugees in humanitarian emergencies.
RESUMO
Attention deficit hyperactivity disorder (ADHD) is among the most prevalent disorders in children and is frequently linked with motor difficulties that can impact both daily motor tasks and overall developmental trajectories. The objective of this study was to analyse the association between gross motor skills and ADHD symptoms. Using a cross-sectional research design, data were collected from a sample of primary school children (N = 2677; mean age = 8.58 years, SD = 1.49 years). The Gross Motor Development-3 Test (TGMD-3) was employed to assess participants' gross motor skills, whereas the ADHD Rating Scale (SDAI), completed by teachers, evaluated ADHD symptoms through two subscales: inattention and impulsivity/hyperactivity. The results revealed an association between motor development and ADHD symptoms, with greater proficiency in gross motor skills correlating with lower symptoms reported on the SDAI. Logistic regression analyses indicated that the TGMD-3 was significantly associated with the risk of ADHD in matched samples of at-risk children and controls. The evaluation of gross motor development proves to be a useful tool for monitoring global development, paying attention to any critical issues, particularly in relation to the variables of inattention and hyperactivity.
RESUMO
The neurobiological effects of transcranial direct current stimulation (tDCS) have still not been unequivocally clarified. Some studies have suggested that the application of tDCS over the inferior frontal gyrus (IFG) enhances different aspects of cognition in healthy and neurological individuals, exerting neural changes over the target area and its neural surroundings. In this systematic review, randomized sham-controlled trials in healthy and neurological adults were selected through a database search to explore whether tDCS over the IFG combined with cognitive training modulates functional connectivity or neural changes. Twenty studies were finally included, among which twelve measured tDCS effects through functional magnetic resonance (fMRI), two through functional near-infrared spectroscopy (fNIRS), and six through electroencephalography (EEG). Due to the high heterogeneity observed across studies, data were qualitatively described and compared to assess reliability. Overall, studies that combined fMRI and tDCS showed widespread changes in functional connectivity at both local and distant brain regions. The findings also suggested that tDCS may also modulate electrophysiological changes underlying the targeted area. However, these outcomes were not always accompanied by corresponding significant behavioral results. This work raises the question concerning the general efficacy of tDCS, the implications of which extend to the steadily increasing tDCS literature.
RESUMO
Non-invasive brain stimulation (NIBS) approaches have seen a rise in utilization in both clinical and basic neuroscience in recent years. Here, we concentrate on the two methods that have received the greatest research: transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS). Both approaches have yielded pertinent data regarding the cortical excitability in subjects in good health as well as pertinent advancements in the management of various clinical disorders. NIBS is a helpful method for comprehending the cortical control of the ANS. Previous research has shown that there are notable changes in muscular sympathetic nerve activity when the motor cortex is modulated. Furthermore, in NIBS investigations, the ANS has been employed more frequently as an outcome measure to comprehend the overall impacts of these methods, including their safety profile. Though there is ample proof that brain stimulation has autonomic effects on animals, new research on the connection between NIBS and the ANS has produced contradictory findings. In order to better understand NIBS processes and ANS function, it is crucial to take into account the reciprocal relationship that exists between central modulation and ANS function.
RESUMO
BACKGROUND: The capacity to change attention from one area to another depending on the many environmental circumstances present is a crucial aspect of selective attention and is strictly correlated to reaction time. The cholinergic system of the basal forebrain is crucial for attentive abilities. Several inputs, particularly orexin neurons, whose cell bodies are found in the postero-lateral hypothalamus, can activate the cholinergic system. The aim of this study was to investigate if high frequencies rTMS at dorsolateral prefrontal cortex (DLPFC) in highly trained volleyball players can change Orexin-A levels, attention and reaction time. This study was a double-blinded (participant and evaluator) matched-pair experimental design. Twenty right-handed female volleyball players were recruited for the study (age 24.6 ± 2.7 years; height 177.0 ± 5.5 cm; body mass 67.5 ± 6.5 kg; BMI 21.5 ± 1.2). RESULTS: The main finding of this study was that 10 Hz rTMS to the DLPFC seems to increase Orexin-A salivary levels and the percentage of correct answers, while decreasing RT. After rTMS, the athletes show an increase in the percentage of correct answers immediately after the end of stimulation, and also after 15 and 30 min. Moreover, the athletes show decreases in reaction time after the end of stimulation and after 15 and 30 min to the end of stimulation, while no differences were found at the end of stimulation. Finally, the athletes show significant increases in Orexin-A salivary levels after stimulation with a peak after 30' of the end. CONCLUSION: The results of our study seem to indicate that there is a relationship between salivary Orexin-A levels and RT. These results could provide useful tools for modulating sports training; in fact, if confirmed, they could lead coaches to offer their athletes rTMS sessions appropriately integrated with training. In fact, alternating attention is a mental flexibility that enables people to change their point of focus and switch between tasks requiring various levels of cognition.
RESUMO
Interpersonal physiological synchrony and collaboration in educational contexts have been identified as key aspects of the learning environment to foster critical thinking, decision-making, problem-solving, and shared knowledge construction and learning of students. In addition to this, teachers' support and interaction with students result in a protective factor for students' well-being and academic outcomes. The main aim of this systematic review was to explore if and how teachers' support and relationship with students can affect their use of Socially Shared Regulatory Strategies for Learning (SSRL). Studies were identified in six electronic databases (Web of Science, Scopus, PubMed, Embase, and Cochrane CENTRAL and ERIC) following PRISMA guidelines. The initial search yielded a total of 110 records. Fifty-nine studies were fully reviewed, and 16 studies met all inclusion criteria and formed the basis for the review. Studies were analyzed and teachers' support strategies to enhance SSRL were identified and recorded. This review identifies a range of teachers' strategies that may foster students' SSRL, such as prompting and moving from one group to another, helping and checking the groups' progress, especially in primary and secondary school; flipped classrooms at university level. The results of this systematic review may inform teachers, educational practitioners, the general public and the design of individualized educational interventions aimed at improving teacher-child relationships, their well-being and academic performance.
RESUMO
Introduction: Special needs teachers deliver crucial care to their students by showing a particular attitude toward them. However, they usually face stressful situations that negatively impact their capacity to support their students, often reporting higher levels of burnout compared to teachers from mainstream education. Self-compassion has been seen to function as a protective factor against teacher stress, enhancing their resilience and coping abilities. Methods: The current study aimed to evaluate the factorial structure, reliability, and validity of the Self-compassion Scale (SCS) in a sample of Italian special needs teachers (R1). In addition, it was investigated whether the satisfactory internal reliability of the SCS is confirmed (R2). Finally, the validity of the SCS criterion was assessed, assuming that each of its subscales would be related to anxiety, measured with GAD-7, and with resilience, measured with the BRS (R3). A sample of 629 teachers was enrolled in this study and completed an online questionnaire. Results: Overall, the confirmatory factor analysis showed good or acceptable indices of fit to the data supporting the use of SCS to measure self-compassion in Italian special needs teachers. Discussion: The tool could be helpful for future research to start exploring the self-compassion dimension at school as a protective factor that may foster teachers' and, consequently, students' well-being.
RESUMO
With the increasing popularity and accessibility of video games, the public concern about their effects - positive and negative - has also increased. In this regard, this systematic review sought to identify and thematically analyze recent studies (in the last five years) and report on video games' epidemiological characteristics and outcomes. A systematic database search was done on ScienceDirect, APA PsycINFO, Emerald, and Scopus databases for articles published from January 1, 2017, to April 1, 2022. The Meta XL software - an add-in for Microsoft Excel - was used to calculate the pooled prevalence level of video game addiction. The database search yielded a total of 693 non-duplicate articles. After applying the inclusion and exclusion criteria, 27 articles were selected to be included in the systematic review. Along with this, 12 articles were considered for the final meta-analysis. The pooled prevalence level of gaming addiction was 5.0 % (95 % CI, 2.1-8.8 %). The I2 value was 99.297 with a p-value of 0.000. The factors that accompanied addictive video gaming were psychological, social, and personal. An addictive gaming behavior was characterized by spending an above-average time on gaming, doing most of the gaming online, and gaming activities interfering with sleep patterns. Some predictors of addictive gaming were emotional dependence, social detachment, increased gaming time, preference for playing online than offline, and increased emotional and psychological stress. Engaging in addictive gaming led to adverse outcomes such as lower academic scores, depression, and anxiety, as well as decreased self-esteem, life satisfaction, and social support. From the collected findings it could be concluded that extreme playing of video games can be classified as addictive. Following the identification of risk factors, appropriate corrective or interventional measures should be developed and applied coherently to newer statistical data.

Introduction: Self-determination construct is a motivation theory used in professional and educational context to foster special needs teachers' development of metacognition, and psychological wellbeing. The Learning Climate Questionnaire (LCQ) is a validate questionnaire used to underly teachers' professional and personal competence, and improving social, emotional and career outcomes. The present paper aims to evaluate the degree of reliability (R1) and the adherence of construct validity to the construct of self-determination (R2) of the Italian adaptation of the LCQ. Methods: A confirmatory factorial analysis was conducted to evaluate the factorial structure of the LCQ in a sample of Italian special needs teachers (N = 953). Teachers was asked to complete an online version of the LCQ. Construct validity was conducted by relating the learning climate with the basic psychological needs satisfaction, measured with PBNSF, and with academic motivation scale, measured with AMS. Results: The analysis showed a good reliability (R1) and construct validity of the Italian adaptation of the questionnaire, with a high internal consistency compared to those obtained in other studies (R2). Discussion: Teachers' autonomy support and teacher-student relation can positively impact the students' psychological factors and enhance students' learning motivation and academic achievement. Findings reveal that higher levels of learning climate could also be a key factor in reducing teachers' negative stress and mental health consequences. Conclusion: This study may facilitate further research about the autonomy-supportive learning climate in educational settings in Italy.
RESUMO
Adolescents who have to make decisions regarding their future career or academic path can be greatly influenced by parental expectations and other individual and contextual factors. The aim of this study is to explore the impact of adolescent-parent career congruence on adolescents' well-being and future intention to enroll in a university course. The recruitment of participants took place through a combination of convenience sampling and snowball sampling. A sample of 142 high school students who are managing their decisions for the future completed an online questionnaire. Data were analyzed through a path analysis (SEM) with observed variables, and different indices were evaluated to check the model goodness of fit. The data show that congruence with parents' wishes has a significant effect on academic motivation, work hope and mattering, which in turn have a positive and significant effect on both future intentions to undertake university studies and on the participants' occupational well-being. In line with past studies, our results demonstrate correlations between adolescent-parent career congruence in career exploration and decision making, pointing out in particular the influence due to complementary congruence with mothers. Furthermore, our study underscores the important role played by both individual and contextual factors in adolescent well-being and intentions for their future. Finally, implications for the practice of vocational guidance practitioners are discussed.
RESUMO
During the COVID-19 pandemic, entire university courses were moved online. This represented a challenge for universities, who were required to move toward an entirely online learning environment without adequate time to manage the change from traditional courses to online courses. However, beyond the emergency of the pandemic, higher education does increasingly incorporate an online learning element, and such a provision does appear to reflect both the desires of modern-day students and university offerings. For this reason, assessing students' online engagement is fundamental, not least because it has been seen to be related both to students' satisfaction and their academic achievement. A validated measure of student online engagement does not exist in Italy. Therefore, this study aims to assess both the factor structure and the validity of the Online Student Engagement (OSE) Scale in the Italian context. A convenience sample of 299 undergraduate university students completed a series of online questionnaires. The Italian OSE scale presents good psychometric properties and represents a valuable instrument for both practitioners and researchers examining students' engagement in online learning.
RESUMO
Since the COVID-19 pandemic, researchers have been trying to identify which personal resources can contribute to minimizing the mental health costs in students incurred due to the restrictions that disrupted safety and predictability in their academic lives. The aim of the study was to verify if and how individual factors (resilience and positivity) and socio-environmental factors (social support and nationality) allow prediction of the level of perceived stress. University students (n = 559) from Poland, Serbia, and Italy were surveyed using the Perceived Stress Scale (PSS-10), the Brief Resilience Scale (BRS), the Positivity Scale (PS), and the Interpersonal Support Evaluation List (ISEL-12). Personal resources-positivity, resilience, and support-were found to be positively interrelated and significantly associated with stress levels. Additionally, gender and nationality differentiated stress levels. A general linear model (GLM) showed that levels of perceived stress are best explained by resilience, positivity, tangible support, and gender. The results obtained can strengthen students' awareness of personal resources and their protective role in maintaining mental health, as well as contribute to the creation of prevention-oriented educational activities. Nationality was not a significant predictor of the level of perceived stress, which highlights the universality of examined predictors among university students from different countries and suggests that interventions aimed at enhancing these resources could benefit students across different cultural contexts.

OBJECTIVES: The ability to redirect one's attention in response to various environmental situations is a crucial aspect of selective attention in team sports. Thus, the aim of this study was to investigate whether repetitive transcranial magnetic stimulation (rTMS) in volleyball players can improve Posner test response and cortical excitability. This study had a double-blinded (participant and evaluator) matched-pair experimental design. METHODS: Twenty right-handed female volleyball players were recruited for the study and randomly assigned to either the active rTMS group (n = 10) or the sham stimulation group (n = 10). The stimulation was performed in one session with 10 Hz, 80% of the resting motor threshold (RMT), 5 s of stimulation, and 15 s of rest, for a total of 1,500 pulses. Before and after stimulation, the Posner test and cortical excitability were evaluated. RESULTS: The significant finding of this paper was that 10 Hz rTMS to the DLPFC seemed to improve Posner test response, and also resulted in a significantly decreased RMT and MEP latency of the ipsilateral motor cortex. After stimulation, the active group showed a significant decrease in the percentage of errors in the Posner test. Moreover, active group showed faster RT after rTMS, suggesting that HF stimulation could enhance performance. Additionally, significant differences in RMT emerged in the active rTMS group after stimulation, while no differences were observed in MEP latency and MEP amplitude. CONCLUSION: In conclusion, we believe that these results may be of great interest to the scientific community and could have practical implications in the future.

BACKGROUND: The years spent at university represent a critical period that can influence both the quality of lifestyle and the eating habits of subsequent adulthood, and also, in the long term, the health of the individual. The aim of this study was to investigate the lifestyle of university students living away from home. METHODS: Each subject recruited for the study was given a questionnaire to obtain general information, eating habits and physical activity levels before (T0) and after six month of training seminars (T1). Blood pressure, body composition and questionnaire responses were investigated. RESULTS: The main findings of this study are a significant decrement in blood pressure; an increment in physical activity practice; an increased number of subjects who pay attention to the calorific value of food and also an improvement in BIA parameters. CONCLUSIONS: In conclusion, this study demonstrated the challenges that university students face in leading a healthy lifestyle and caring for their nutritional needs, particularly when they are away from their families. No intervention specifically targets young adults, even though much emphasis is placed on the promotion of a healthy lifestyle based on a varied and balanced diet and sufficient exercise. Our study showed that it is possible to improve lifestyle through educational events aimed at making students aware of the health risks deriving from unhealthy lifestyles.

BACKGROUND: Trauma survivors are at a high risk of developing mental health problems. Hence, mental help in the form of emergency psychology has to be availed in the aftermath of a traumatizing event. When studied in-depth, emergency psychology comprises protocols, strategies, and techniques that establish it as an interventional activity. OBJECTIVE: The main of this review is to analyze how emergency psychology services are provided to people, to verify to what extent these interventions are homogeneous in the delivery methods and consequently, facilitate the creation of relevant measures. Consequently, the general view of emergency psychology is reviewed and analyzed to identify the protocols, guidelines, and strategies used. METHODS: A search was done on the ScienceDirect, APA PsycINFO, Emerald, and Scopus databases for articles published from 1st January 2017 to 1st April 2022. The reference lists of the identified studies were also screened. RESULTS: After the non-duplicate articles were removed and after filtering the articles according to inclusion criteria, 20 articles were included for the thematic analysis: nine research articles, 10 case study reports, and one randomized controlled trial (RCT). During the analysis, different aspects of emergency psychology were categorized: Responders, Crisis Management and Structure, and types of psychological interventions. This categorization led to the identification of protocols, guidelines, and strategies that can be placed in a sequence to give a general direction of how an emergency psychology intervention is supposed to be carried out. CONCLUSIONS: The adopted protocols, guidelines and strategies may vary from one disaster management to another but the main goal will always remain the same.
