Electronic media such as mobile phones, social media, computers, televisions, and video games are dominant in adolescents' lives. There is a growing concern that rising rates of electronic media use may be related to behavioral and emotional problems. The aim of the present study was to examine associations of adolescents' electronic media use with attention-deficit/hyperactivity disorder (ADHD) symptoms. Study participants were 99 adolescents (39 males, 60 females), 12-18years old, as well as 93 parents (12 fathers and 81 mothers). Internet addiction was evaluated by the Internet Addiction Test (IAT) and behavioral/emotional problems by the Achenbach System of Empirically Based Assessment. Parents reported on their adolescent's attention and hyperactivity problems on the ADHD Rating Scale-5. Electronic media used by the adolescents were computer (40.4%), tablet (44.4%), PlayStation (40.4%), Facebook (43.4%), whereas 72.7% had an account on social networks. They watched TV from 0 to over 4h every day; specifically, 51.5% from 0 to 2h, while only 1% over 4h. Most of them (78.8%) used internet daily, 28.3% used internet about 6-10h, and 24.2% used it over 20h to watch videos on YouTube (20,2%), searched for school information (14,1%), connected with social media (13.1), played games (12.1%), looked for information on products and services (12.1%), etc. Eighty respondents (80.8%) were average internet users (IAT<40), 19 (19.2%) had possible addiction (IAT 40-69), while no one (0%) had severe addiction (IAT≥70). The Internet Αddiction scale was found to have statistically significant correlations with many of the subscales of the Achenbach questionnaire and the attention-deficit subscale of the ADHD questionnaire.Statistically significant positive correlations were found between possible internet addiction with rule-breaking behavior, problems like thought, externalization, behavioral, obsessive-compulsive behavior, and post-traumatic stress. Results suggest that misuse of electronic media may be related to ADHD traits among Greek adolescents. As rates of electronic media use among teenagers are increasing, these findings should be taken into account to protect the social, cognitive, and psychological health of adolescents. Effective interventions are needed to target specific types of electronic media use in adolescence.

Contemporary parenting involves technology-related challenges such as establishing guidelines for how 10-19-year-old adolescents use social media. Previous research has shown inconsistent findings on strategies that parents adopt in helping their adolescents navigate the use of social media. It is unclear how parenting practices contribute to shaping adolescents' digital literacy. Thus, the current review aimed to explore the relationship between parental factors and adolescent social media use. We conducted systematic literature searches in four online databases: Scopus, PubMed, PsycINFO, and ERIC. Based on predefined eligibility, the search yielded 27 studies (19 cross-sectional) mainly conducted in Europe, the United States, and Asia Pacific involving 26,337 adolescents. Four aspects of parenting practices (parent modelling, mediation/communication, monitoring, and limit-setting) were identified that were linked with adolescent engagement with social media. Adolescents mirror their parents' social media habits, including time spent online and specific behaviours like privacy settings. Specifically, parental mediation positively correlated with adolescent social media engagement while parental monitoring showed mixed results on adolescent social media use. Additionally, proactive limit-setting strategies appeared to mitigate problematic social media use, while reactive approaches were associated with increased social media use. This review demonstrates the multifaceted role of parental practices, particularly modelling and mediation/communication, in shaping adolescent social media use behaviours. It also highlights the need for further research to delineate the nuanced effects of monitoring and limit-setting, emphasising the importance of considering individual adolescent needs and family dynamics in the development of effective intervention strategies.

The aim of this study is to determine the relationship between university students' social media usage habits and motivations and their virtual loneliness levels. The research, designed as a descriptive and cross-sectional study, was carried out between 7 May and 4 June 2024 and completed with the help of a total of 2480 university students. Data were collected with a questionnaire form, the "Virtual Environment Loneliness Scale (VELS)" and the "Social Media Use Habits and Motivations Scale (SMUHMS)".A descriptive statistic, a t-test, an ANOVA, and Pearson correlation and regression tests were used to analyse the data. University students reported high levels of social media use and moderate levels of virtual loneliness. A significant positive correlation was found between social media use and virtual loneliness. Female students had higher social media usage, whereas male students experienced greater virtual loneliness. Both social media use and virtual loneliness were higher among students aged 18-24, those whose parents had a bachelor's degree or higher, and those spending six or more hours per day on social media. Additionally, social media use habits and motivations together accounted for 21% of the variance in virtual loneliness. To build sustainable and meaningful relationships on social media, there is a need to develop conscious usage strategies. In addition to interventions that support digital awareness and conscious media consumption from childhood to university to reduce virtual loneliness, university students' access to social environments and activities where they can have quality face-to-face interaction should be increased.

Introduction: The purpose of this study was to examine the effects of 30 min of social media (SM) use on salivary cortisol, countermovement jump, reaction time, agility, and anaerobic capacity. Methods: Ten physically active college students (five males and five females) completed the randomized, repeated-measures, crossover design study. Participants completed two trials: 30 min of SM or 30 min of a neutral video. Heart rate and blood pressure were measured during treatment. Salivary cortisol, affect, and Stroop task scores were measured before and after treatment, then participants completed several high-intensity exercise tasks. Treatments were administered at least 48 h apart. Results: No significant differences were found between treatments for vertical jump (median = 0.63 cm; P = 0.18), running reaction time (median = − 0.035 s; P = 0.65), local reaction (median = − 0.32 in; P = 0.71), agility (median = − 0.46 s; P = 0.47), and anaerobic run time (median = 2.5 s; P = 0.39). No significant interaction was found for the Stroop task ( F (1,9) = 0.86; P = 0.38) or salivary cortisol ( F (2,18) = 0.75; P = 0.49) between treatments over time. Conclusion: SM use before exercise did not negatively affect exercise performance, Stroop task scores, or stress after acute treatment.

Rationale: Obesity-associated metabolic diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes mellitus (T2DM) are increasing rapidly, necessitating physiologically relevant in vitro models of the liver-pancreas axis. While recent multi-organoid systems have advanced inter-organ modeling, many systems still fall short of replicating the complex and directional metabolic interactions required to accurately reflect disease progression. This is partly due to inherent limitations such as reliance on passive diffusion for metabolic exchange and the use of shared or non-compartmentalized media, which restrict tissue-specific functions and fail to mimic in vivo-like physiological gradients.Methods: To overcome these limitations, we developed a multi-organoid device (MOD) that incorporates convective flow and physically separates liver and pancreatic organoids in distinct media environments. To evaluate the effectiveness of this co-culture system, we assessed metabolic transport using FITC-dextran and examined pancreatic and liver organoid function by measuring insulin and albumin secretion respectively. The effectiveness of the MOD in modeling MASLD-induced T2DM was further validated through functional assays and transcriptomic analysis.Results: The MOD successfully recapitulated key pathological features of MASLD-induced T2DM. Convective flow significantly enhanced directional transport of glucose and other metabolic molecules compared to passive diffusion, as validated by simulation and diffusion assays. Media separation preserved organoid function, increasing insulin and albumin secretion by 1.8- and 1.6-fold, respectively, compared with the non-separated group. Importantly, the device achieved rapid glucose regulation following glucose stimulation, with normoglycemia restored within 2 hours closely mimicking physiological glucose regulation not previously attainable in existing systems. Under MASLD conditions, the platform further revealed that liver-derived Fetuin-A was associated with β-cell apoptosis in pancreatic organoids.Conclusion: This MOD effectively models the pathophysiological cascade linking MASLD and T2DM by integrating organ-specific environments, convective flow, and multi-organ crosstalk. It offers a robust and biologically relevant tool for mechanistic studies of metabolic diseases and provides a promising platform for preclinical drug screening and therapeutic development.

Guidance and regulation for the use of social media (SM) by healthcare professionals (HCPs) is lacking in some parts of the world. This paper explores the significance and barriers of SM in oncology care in regions beyond Europe and North America. A cross-sectional survey facilitated by Sermo to explore the use of SM among oncologists in Argentina, Brazil, India, Mexico, Saudi Arabia, Taiwan, Türkiye, and the United Arab Emirates was conducted between 14 June 2023 and 28 June 2023. A panel discussion involving seven digital opinion leaders (DOLs) was also held. Of 340 respondents, the survey found strong support for SM in public and HCP education with most preferring mobile phones and 88% accessing SM in their free time. SM has an average-to-great impact on the prescribing habits of 52% of respondents. Sixty-four percent of respondents are concerned about potential conflicts of interest with SM. The panel developed a framework of recommendations providing navigational aids for key information, verifying sources to avoid misinformation, disclosing conflicts of interests, and creating visual and bite-sized content. Opportunities exist to enhance SM use in regions beyond Europe and North America. DOLs in oncology can enhance SM content quality.

Limited technological infrastructure, suboptimal teacher skills, and the dominance of conventional learning methods continue to hamper the implementation of interactive educational resources in elementary schools. This study aims to analyze the effect of interactive media on student learning motivation. The method is a qualitative case study of two teachers in grades 4 and 5. Data were obtained through observation, interviews, and documentation, then analyzed using the Miles &amp; Huberman model, which includes data reduction, data presentation, and conclusion. The results show that interactive media can increase student engagement, enthusiasm, and understanding of the material, while also facilitating teachers in delivering learning and creating a more enjoyable and collaborative classroom atmosphere. The implications of this study emphasize the importance of improving teachers' competence and the availability of technological facilities so that the use of interactive media can operate optimally to enhance the quality of learning in elementary schools.
