RESUMO
Single nucleotide variants in the general population are common genomic alterations, where the majority are presumed to be silent polymorphisms without known clinical significance. Using human induced pluripotent stem cell (hiPSC) cerebral organoid modeling of the 1.4 megabase Neurofibromatosis type 1 (NF1) deletion syndrome, we previously discovered that the cytokine receptor-like factor-3 (CRLF3) gene, which is co-deleted with the NF1 gene, functions as a major regulator of neuronal maturation. Moreover, children with NF1 and the CRLF3L389P variant have greater autism burden, suggesting that this gene might be important for neurologic function. To explore the functional consequences of this variant, we generated CRLF3L389P-mutant hiPSC lines and Crlf3L389P-mutant genetically engineered mice. While this variant does not impair protein expression, brain structure, or mouse behavior, CRLF3L389P-mutant human cerebral organoids and mouse brains exhibit impaired neuronal maturation and dendrite formation. In addition, Crlf3L389P-mutant mouse neurons have reduced dendrite lengths and branching, without any axonal deficits. Moreover, Crlf3L389P-mutant mouse hippocampal neurons have decreased firing rates and synaptic current amplitudes relative to wild type controls. Taken together, these findings establish the CRLF3L389P variant as functionally deleterious and suggest that it may be a neurodevelopmental disease modifier.

BACKGROUND: Despite evidence on socioeconomic inequalities in psychosocial well-being of adolescents under the COVID-19 pandemic, the explanatory factors and their potential variations across contexts remained understudied. Hence, this cross-regional study compared the extent of inequalities and the mediating pathways across Hong Kong, Mainland China, and the Netherlands. METHODS: Between July 2021 and January 2022, 25 secondary schools from diverse socioeconomic background were purposively sampled from Hong Kong, Zhejiang (Mainland China), and Limburg (the Netherlands). 3595 junior students completed an online survey during class about their socioeconomic position, psychosocial factors, and well-being. Socioeconomic inequalities were assessed by multiple linear regressions using the Slope Index of Inequality (SII), whereas the mediating pathways through learning difficulty, overall worry about COVID-19, impact on family' financial status, resilience, trust in government regarding pandemic management, and adaptation to social distancing were examined by mediation analyses moderated by regions. RESULTS: The adverse psychosocial impact of COVID-19 was stronger in the Netherlands and Hong Kong compared with Mainland China. The greatest extent of socioeconomic inequalities in the change in psychosocial well-being was observed among students in the Netherlands (SII = 0.59 [95% CI = 0.38-0.80]), followed by Hong Kong (SII = 0.37 [0.21-0.52]) and Mainland China (SII = 0.12 [0.00-0.23]). Learning difficulty and resilience were the major mediators in Mainland China and Hong Kong, but to a lesser extent in the Netherlands. CONCLUSION: Socioeconomic inequalities in psychosocial well-being were evident among adolescents under the pandemic, with learning difficulty and resilience of students as the key mediators. Differences in the social contexts should be considered to better understand the variations in inequalities and mediating pathways across regions.
RESUMO
AIMS: The objective of this study was to examine the relationship between caregiving burden and pre-death grief, with a specific focus on adult-child caregivers in mainland China. Additionally, the study explored whether coping strategies played a mediating role in this correlation. METHODS: A convenience sample of 320 adult-child caregivers of older parents with dementia from Kunming, mainland China, was recruited for the study. Data were collected using the Chinese version of the Marwit-Meuser Caregiver Grief Inventory-Short Form, the Burden Scale for Family Caregivers, and the Ways of Coping Checklist-Revised. RESULTS: Results using linear regression and multiple mediation analysis with Hayes' process model indicated that caregiving burden was positively related to pre-death grief and that active coping mediated the relationship between them. In the female group, active coping partially mediated the association between caregiving burden and pre-death grief, but in the male group, this mediating effect did not exist. CONCLUSION: The study found evidence supporting the link between caregiving burden and pre-death grief among adult-child caregivers of older parents with dementia in mainland China. Furthermore, the caregiving burden prevented the use of active coping, and this decrease in coping increased the perception of pre-death grief. These associations only existed in the female group. IMPLICATIONS: This paper presented the importance of active coping skills in the dementia caregiving process. IMPACT: The findings of this study emphasize the necessity for health practitioners to provide targeted interventions regarding pre-death grief among dementia caregivers and strengthen caregivers' active coping strategies to reduce their pre-death grief. Community-based and personal care support services should be promoted to alleviate their caregiving burden. REPORTING METHOD: We have adhered to the transparent reporting of evaluations with quantitative design statements and the corresponding checklist was followed. PATIENT OR PUBLIC CONTRIBUTION: 'No patient or public involvement'.

Despite contradictory empirical evidence, some suggest that physical exercise is directly related to bullying perpetration. Moreover, the quality of social relationships between adolescents and their parents, peers, and teachers has been proposed as a crucial mediator in the relationship between physical exercise and bullying perpetration. However, few empirical studies have examined such hypotheses. This study used data obtained from the 2014-2015 China Education Panel Survey to examine the direct association between physical exercise and bullying behaviors, as well as the indirect pathways from physical exercise to bullying that are mediated by teenagers' social relationship quality. The results showed no significant direct relationship between physical exercise and bullying behaviors. However, physical exercise has indirect associations with bullying behaviors mediated through social relationship quality, with peer relationships having the strongest mediating effect. The findings indicate that social relationships could mediate the association between physical exercise and bullying behaviors. The study suggests that future prevention and intervention programs should promote adolescents' participation in physical exercise and their social interactions with parents, peers, and teachers to reduce bullying perpetration.
RESUMO
BACKGROUND: Caregiving for a parent with dementia has both positive and negative influences on psychological well-being of adult children and perceived social support plays an essential role in dementia caregiving process. OBJECTIVES: We examined how the degree of caregiving intensity influences mental health among Chinese adult children then further explored how perceived social support influences the relationship between intensity and psychological well-being. RESEARCH DESIGN AND SETTING: Cross-sectional study in Kunming, mainland China between November 2022 and January 2023. METHODS: We interviewed 320 adult dementia child caregivers. Linear regression and multiple mediation analysis using Hayes' process model were used to assess the relationship between caregiving intensity and psychological well-being, as well as the mediating role of perceived social support. RESULTS: The study found that caregiving intensity was positively associated with depression and negatively associated with life satisfaction. A lack of perceived social support exacerbated these effects for the adult children. Specifically, the caregivers reported higher caregiving intensity when they perceived less family support, which is in turn associated with greater depression and lower life satisfaction among the caregivers. Likewise, those who reported higher caregiving intensity was reported lower friend support, which was in turn associated with greater depression. CONCLUSIONS AND IMPLICATIONS: The findings emphasize the importance of social support, especially family support, and the necessity for health practitioners to provide targeted interventions on both negative and positive aspects of psychological well-being among dementia caregivers and to strengthen caregivers' resources for social support to enhance their well-being. While these findings are cross-sectional, it is logical to assume that those who perceive less support feel that their caregiving responsibilities are more intense, and that intensity could cause the caregiver to withdraw from friends.

This study aims to expand our understanding of the relations of oral reading fluency at word, sentence, and passage levels to reading comprehension in Chinese-speaking secondary school-aged students. In total, 80 participants (46 males and 34 females) ranging from 13 to 15 years old joined this study and were tested on tasks of oral reading fluency at three levels, reading comprehension, and nonverbal IQ. Our results showed a clear relationship from fluency at the level of the word to the sentence and then the passage in oral reading fluency as well as both the direct and indirect importance of word-level oral reading fluency in reading comprehension. Only the indirect effect from word-level oral reading fluency to reading comprehension through passage-level oral reading fluency was significant. Our findings suggest that sentence-level oral reading fluency is the crucial component to reading comprehension in Chinese. Additionally, recognition of the potential value of unique features, such as syntactic awareness and word segment accuracy, that happen at the sentence level should be integrated into instructional activities for reading.

Sexually exploited adolescent girls are disproportionately affected by adverse psychosocial conditions, such as intra-familial child physical and sexual abuse, extra-familial violence and sexual assault, alcohol and drug use, and suicide. Syndemic theory suggests that these adverse psychosocial or syndemic conditions are concentrated and co-occurring in socially marginalized populations, including sexually exploited adolescents, and increase their sexual health risks, including pregnancy, abortion, and the acquisition of sexually transmitted diseases (STDs). To examine clusters of syndemic conditions, latent class analysis (LCA) was conducted to classify 335 sexually exploited girls in Taiwan into subgroups based on their probability of experiencing each syndemic condition. We used syndemic class membership to predict their sexual health outcomes, specifically pregnancy, abortion, and the acquisition of STDs. The results of LCA revealed three classes, which were "low-risk syndemic," "moderate-risk syndemic," and "high-risk syndemic." The risk of acquisition of STDs among sexually exploited girls in the "high-risk syndemic class" and "moderate-risk syndemic class" was 239% and 135% higher, respectively, than the risk of acquisition of STDs among sexually exploited girls in the "low-risk syndemic class." Differences between these three classes in pregnancy and abortion were not significant. Our findings support the syndemic theory that a pattern of syndemic conditions is associated with an increased risk of acquiring STDs. Interventions aimed at reducing the acquisition of STDs among sexually exploited girls in Taiwan should adopt a comprehensive approach to address co-occurring conditions.

BACKGROUND: The Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) is a consistent and comprehensive instrument to assess symptoms of specific internet-use disorders including those related to gaming, shopping, pornography use disorder, social networks use and gambling considering criteria in the eleventh revision of the International Classification of Diseases (ICD-11). However, to date, there is little evidence supporting instruments assessing major types of specific internet use disorders in Thailand. The aim of this present study was to assess the psychometric properties of the ACSID-11 among Thai young adults. METHODS: A total of 612 participants were recruited. A confirmatory factor analysis (CFA) examined construct validity of the ACSID-11. Cronbach's α and McDonald's ω were used to assess reliability of the ACSID-11. Pearson correlations examined relationships between ACSID-11 domains and Internet Gaming Disorder Scale-Short Form (IGDS9-SF) scores. RESULTS: The CFA supported validity of the Thai version of the ACSID-11 and a four-factor structure. Specific domains of the Thai ACSID-11, particularly gaming, were positively and significantly correlated with IGDS9-SF scores. CONCLUSIONS: Data indicate that the Thai version of the ACSID-11 is a valid and reliable instrument to assess major types of specific internet use disorders. Additional studies are needed to further examine the validity and reliability of the Thai ACSID-11.

The current study aims to examine prosodic sensitivity in Chinese children with dyslexia and its relation to Chinese reading in children with and without dyslexia. A total of 172 Chinese children from third grade to sixth grade in Taiwanese primary schools were recruited. Thirty (14 male) children were identified as having dyslexia, and the remaining children (N = 142; 67 male) were typically developing children matched with those with dyslexia as carefully as possible with respect to school, grade, and gender. Our results indicated that group differences were found for all three types of prosodic sensitivity. Moderation analyses showed that group had no significant interaction with prosodic sensitivity in predicting Chinese reading, so the participants in the two groups were combined in the following analyses. The results of the stepwise regression analyses showed that only lexical tone awareness could significantly predict Chinese character reading after controlling for phonological awareness, while only intonation awareness could significantly predict reading comprehension after controlling for Chinese character reading. The results provide preliminary evidence on the issue of prosodic sensitivity in Chinese children with dyslexia and its role in Chinese reading, which might provide a novel approach to the teaching of Chinese languages.

PURPOSE: The current study explores which types of delinquent activities bullies, victims, and bully/victims are most at risk of from a sample of urban African American adolescents. DESIGN AND METHODS: The research design was cross-sectional, which includes a sample of low-income African American adolescents in Chicago's Southside. The study participants included 523 adolescents. Descriptive statistics, latent class analysis, and logistic regression analysis were conducted. RESULTS: Bullies, victims, and bully/victims are all at a heightened risk of theft, threatening behavior, and assaultive behavior. Irrespective of bullying status, delinquency is a serious problem for urban adolescents who are bullies, victims, or bully/victims. CONCLUSIONS: Investigating the types of delinquent activities bullies, victims, and bully/victims are most likely to be involved in is important. IMPLICATIONS FOR PRACTICE: Evidence-based treatment plans require assessment tools that are tailored for urban African American adolescents. Nurses are advised to consider interventions that promote resilience.

BACKGROUND: With the recognition that noncancerous cells function as critical regulators of brain tumor growth, we recently demonstrated that neurons drive low-grade glioma initiation and progression. Using mouse models of neurofibromatosis type 1 (NF1)-associated optic pathway glioma (OPG), we showed that Nf1 mutation induces neuronal hyperexcitability and midkine expression, which activates an immune axis to support tumor growth, such that high-dose lamotrigine treatment reduces Nf1-OPG proliferation. Herein, we execute a series of complementary experiments to address several key knowledge gaps relevant to future clinical translation. METHODS: We leverage a collection of Nf1-mutant mice that spontaneously develop OPGs to alter both germline and retinal neuron-specific midkine expression. Nf1-mutant mice harboring several different NF1 patient-derived germline mutations were employed to evaluate neuronal excitability and midkine expression. Two distinct Nf1-OPG preclinical mouse models were used to assess lamotrigine effects on tumor progression and growth in vivo. RESULTS: We establish that neuronal midkine is both necessary and sufficient for Nf1-OPG growth, demonstrating an obligate relationship between germline Nf1 mutation, neuronal excitability, midkine production, and Nf1-OPG proliferation. We show anti-epileptic drug (lamotrigine) specificity in suppressing neuronal midkine production. Relevant to clinical translation, lamotrigine prevents Nf1-OPG progression and suppresses the growth of existing tumors for months following drug cessation. Importantly, lamotrigine abrogates tumor growth in two Nf1-OPG strains using pediatric epilepsy clinical dosing. CONCLUSIONS: Together, these findings establish midkine and neuronal hyperexcitability as targetable drivers of Nf1-OPG growth and support the use of lamotrigine as a potential chemoprevention or chemotherapy agent for children with NF1-OPG.

Tissue injury and tumorigenesis share many cellular and molecular features, including immune cell (T cells, monocytes) infiltration and inflammatory factor (cytokines, chemokines) elaboration. Their common pathobiology raises the intriguing possibility that brain injury could create a tissue microenvironment permissive for tumor formation. Leveraging several murine models of the Neurofibromatosis type 1 (NF1) cancer predisposition syndrome and two experimental methods of brain injury, we demonstrate that both optic nerve crush and diffuse traumatic brain injury induce optic glioma (OPG) formation in mice harboring Nf1-deficient preneoplastic progenitors. We further elucidate the underlying molecular and cellular mechanisms, whereby glutamate released from damaged neurons stimulates IL-1ß release by oligodendrocytes to induce microglia expression of Ccl5, a growth factor critical for Nf1-OPG formation. Interruption of this cellular circuit using glutamate receptor, IL-1ß or Ccl5 inhibitors abrogates injury-induced glioma progression, thus establishing a causative relationship between injury and tumorigenesis.

BACKGROUND AND OBJECTIVES: Psychosocial factors affect individuals' desire for physical activity. A newly developed instrument (Tendency to Avoid Physical Activity and Sport; TAPAS) has been designed to assess the avoidance of physical activity. Considering cultural differences could be decisive factors, the present study aimed to translate and validate the TAPAS into Chinese (Mandarin) for Taiwanese youths, and further cultural comparisons are expected. METHODS: Standard translation procedure (i.e., forward translation, back translation, and reconciliation) was used to translate the English TAPAS into the Chinese TAPAS. Following translation, 608 youths (mean [SD] age 29.10 [6.36] years; 333 [54.8%] women) participated in the study via a snowballing sampling method with an online survey. All participants completed the Chinese TAPAS and additional instruments assessing weight stigma and psychological distress. Confirmatory factor analysis (CFA) was used to examine the factor structure of the Chinese TAPAS and multigroup CFA to examine measurement invariance across gender (men vs. women) and weight status (overweight vs. non-overweight). Pearson correlations were used to examine the concurrent validity; independent t-tests between gender groups and weight status groups were used to examine the known-group validity. RESULTS: Consistent with the English version, the Chinese TAPAS was found to have a one-factor structure evidenced by CFA results. The structure was invariant across gender and weight status groups evidenced by multigroup CFA results. Concurrent validity was supported by significant associations with the related constructs assessed (r = 0.326 to 0.676; p < 0.001). Known-group validity was supported by the significant differences in TAPAS total scores between gender and weight status groups (p = 0.004 and < 0.001; Cohen's d = 0.24 and 0.48). CONCLUSION: The Chinese version of the TAPAS is a valid and reliable instrument assessing individuals' avoidance of physical activity and sports due to underlying psychosocial issues among Taiwanese youths. It is anticipated to be applied within a large Asian population, as well as cross-cultural comparisons, for further explorations in health, behavioral and epidemiological research and practice.

Background: Problematic use of internet (PUI) may have negative impacts on psychological distress and quality of life (QoL). This situation might be more profound in people with attention-deficit/hyperactivity disorder (ADHD) due to poorer behavioral control and regulatory capacity. However, there is little evidence regarding mediated effects in the associations between PUI, psychological distress, and QoL in people with ADHD. Aims: To investigate mediating effects of psychological distress in the associations of problematic smartphone use (PSPU), problematic use of social media (PUSM), and problematic gaming (PG) with QoL in individuals with ADHD. Methods and Procedures: PUI behaviors of participants with ADHD (n = 99) were assessed using the Smartphone Application-Based Addiction Scale, Bergen Social Media Addiction Scale, and Internet Gaming Disorder-Short Form. Psychological distress was assessed using the Depression, Anxiety, Stress Scale and QoL using the Kid-KINDL. Outcomes and Results: Psychological distress mediated the associations between PUI and different domains of QoL, except for self-esteem QoL. There were also positively direct effects between PG and physical QoL, PUSM and friends' QoL, and PSPU and physical QoL. Conclusions and Implications: PUI may associate with poor QoL in people with ADHD via psychological distress. Programs on reducing PUI for people with ADHD are needed.
RESUMO
OBJECTIVE: The current study attempted to explore the possible temporal direction of the relationship between sleep problems and non-physical bullying perpetration as well as non-physical bullying victimization among adolescents. DESIGN: The study used a longitudinal panel survey design with a 6-month interval. SETTING: A cluster random sampling method was conducted to recruit students from junior high schools in Northern Taiwan. PARTICIPANTS: Eight hundred twenty-two students (46.6% were boys) completed a survey at 2 waves. MEASUREMENT: Adolescents reported their sleep problems, non-physical bullying perpetration, and non-physical bullying victimization in both waves. RESULTS: The results from cross-lagged panel models revealed that sleep problems at time 1 significantly predicted non-physical bullying victimization at time 2, but not in the opposite direction. In addition, non-physical bullying perpetration at time 1 significantly predicted sleep problems at time 2, but not in the opposite direction. No significant differences emerged between male and female adolescents in the cross-lagged model of sleep problems with non-physical bullying perpetration and non-physical bullying victimization. CONCLUSION: This study advances the literature by revealing that sleep problems may be a consequence, not a precursor, of adolescent non-physical bullying perpetration and a precursor, not a consequence, of non-physical bullying victimization. Intervention programs aimed at preventing adolescents from being non-physically bullied may consider improving their sleep quality. Reducing adolescents' non-physical bullying perpetration may also improve sleep quality along the way.

School victimization among children and youth is a global public health issue that has long-term adverse effects on the victims' mental health and behavioral development. Theories and research suggest that emotional intelligence may operate as a buffer against school bullying victimization. However, the strength of the association between emotional intelligence and bullying victimization is controversial. Therefore, we aimed to conduct a meta-analysis to evaluate the exact association between Emotional intelligence and school bullying victimization. We conducted a systematic search in PubMed, Web of Science, ProQuest Dissertations, Google Scholar, and China National Knowledge Infrastructure (CNKI) from inception to March 2022 for relevant studies that examine the association between emotional intelligence and school bullying victimization without a language limit. Twenty-four articles were included in our meta-analysis (n = 27,438). There was a small, negative, and significant association between emotional intelligence and school victimization among children and youth students. Sex and emotional intelligence measurement tools were variables that significantly moderated the link between emotional intelligence and bullying victimization. The findings indicated that improving students' emotional intelligence could be a crucial strategy to lower the students' risk of being bullied in school and online. It would be more effective among male students.

Previous research has suggested that psychological distress (i.e., anxiety, depression, and somatization) is associated with student victimization by teachers. The direction and causality of this relationship have not yet been empirically supported. This study examined longitudinal associations between adolescent psychological distress (anxiety, depression, and somatization) and student victimization by teachers among 419 adolescents in grades 7-9 of secondary schools in Hong Kong. A self-administered questionnaire was conducted to collect student self-reported information about their experiences of victimization by teachers and their psychological distress, including depression, anxiety, and somatization, at two time points separated by a 9-month interval. A cross-lagged panel analysis provided evidence for the contribution of depression, anxiety, and somatization to later victimization by teachers. These findings were also relevant for male and female adolescents. The findings suggest that psychological distress, such as depression, anxiety, and somatization, is a risk factor predicting student victimization by teachers rather than the consequences of exposure to teacher violence. The results support the importance of reducing adolescent depression, anxiety, and somatization symptoms in future intervention programs to prevent them from being victimized by teachers.

Despite a hypothesized link between family conflict and school bullying perpetration, previous findings on the direct association have been inconsistent. It has been argued that affiliation with delinquent peers may be a potential psychosocial mechanism mediating the relationships between family conflict and school perpetration. However, such a proposition has not been examined employing longitudinal panel data. Using longitudinal panel data (two waves with a 9-month interval) from Hong Kong collected from 424 lower secondary students (grades 7-9), this study examined how affiliation with delinquent peers mediates the relationships between family conflict and adolescent school perpetration. The results of the half-longitudinal mediation model indicated no significant link between family conflict at T1 and school bullying perpetration at T2. However, family conflict at T1 was indirectly linked to school bullying perpetration at T2 through affiliation with delinquent peers. The findings imply that affiliation with delinquent peers mediates the association between family conflict and adolescent school bullying perpetration. The findings provide insights into the future development of policies and interventions to reduce school bullying perpetration.

BACKGROUND AND OBJECTIVE: Previous cross-sectional research suggested a link between parental corporal punishment, school violence, and cyberbullying among adolescents. However, their temporal relationships remain unclear. This study used longitudinal panel data to examine the temporal relationships between parental corporal punishment, adolescent school violence against peers and teachers, and cyberbullying perpetration. PARTICIPANTS AND SETTING: Seven hundred and two junior high school students from Taiwan participated. METHODS: A probability sample and two waves of longitudinal panel data collected a nine-month apart were analyzed. A self-administered questionnaire was used to collect students' self-reported information about their experiences of parental corporal punishment, perpetration of school violence against peers and teachers, and cyberbullying. RESULTS: Parental corporal punishment at Time 1 predicted violence against school peers, violence against teachers, and cyberbullying perpetration at Time 2; however, these three behaviors at Time 1 did not predict parental corporal punishment at Time 2. These findings applied to both sex groups, although the effects of parental corporal punishment on violence against teachers were slightly stronger for boys than girls. CONCLUSIONS: Parental corporal punishment is a predictor rather than an outcome of adolescent school violence against peers and teachers and cyberbullying. Policies and interventions need to target parental corporal punishment to prevent adolescents from engaging in violence against peers and teachers and cyberbullying.

Although the associations between adolescent psychological distress (i.e., depression, anxiety, and somatization), school violence, and cyberbullying have been examined using cross-sectional data, little evidence from longitudinal panel data exists to determine the temporal association. A two-wave longitudinal panel data with a 10-month interval were obtained from a random sample of 487 Chinese junior high school students (grades 7-9) in Tianjin in Mainland China. The cross-lagged panel analysis showed that adolescent psychological distress in the first wave of the survey was significantly associated with subsequent school violence against peers and teachers in the second wave but not in the opposite direction. Student psychological distress in the first wave of the survey was not significantly associated with cyberbullying perpetration in the second wave and vice versa. The findings suggested that adolescent psychological distress was a risk factor rather than the consequence of violence against peers and teachers in school. However, the temporal associations between adolescent psychological distress and cyberbullying perpetration were non-significant. These findings were relevant to both sex groups. The findings may imply that potential interventions and policies to prevent students from committing school violence should consider reducing students' psychological distress as one of the core elements.
