Evaluation of the Effects of Educational Interventions on the Modification of High-Risk Job Behaviors in Patients with Brucellosis in Rural Areas of Arak County based on the Family-Centered Empowerment Model (FCEM)

Background and Objectives: Brucellosis is a common disease worldwide. Family-centered empowerment model is a model for empowering patients to modify high-risk behaviors. Given the wide range of health and economic complications caused by the prevalence of brucellosis in society, we sought to evaluate the effect of this model in modifying the high-risk behaviors of patients with brucellosis. Methods: The present study was a quasi-experimental interventional study that examined 88 patients with Brucellosis in Arak County in 2021. Data were collected using a standardized questionnaire based on the family-centered empowerment model in six constructs, namely knowledge, attitude, perceived severity, self-esteem, self-efficacy, and behavior at two stages before and two months after the educational intervention. Independent t-test, paired t-test, and chi-square test at a significance level of 0.05 were used to analyze the data. Results: The mean of patients' age was 42.19±19.79. The results of the paired t-test indicated that the mean scores of knowledge (P<0.001), attitude (P<0.001), perceived severity (P<0.001), self-esteem (P<0.001), self-efficacy (P<0.001), and behavior (P<0.001) significantly increased in the intervention group after education. but changes in mean scores of knowledge (P=0.71), attitude (P= 0.53), perceived severity (P=0.26), self-esteem (P=0.18), self-efficacy (P=0.21), and behavior (P=0.41) were not significant in the control group. Conclusion: The results indicated that educational intervention based on the family-centered empowerment model could be effective in increasing knowledge, thereby improving Brucellosis prevention behaviors.

Challenging Childhood Obesity: The Influence of Education and Close Monitoring on Obesity-Related Behaviors.

We aimed to evaluate the role of nutrition and behavior education intervention in the prevention and treatment of childhood obesity by comparing changes in obesity-related characteristics among obese children during a follow-up period of 12 months. This study was designed as a prospective cohort study in children aged between 6 and 18 years, with exogenous obesity who applied to Istanbul Research and Training Hospital, Pediatrics Department, between January 2018 and July 2019. Beginning at the sixth month, a program for nutrition and behavior education for obesity prevention and treatment was initiated and continued during the second half of the study period. The mean age of 59 children (29 females, 30 males) was 11.73 ± 2.78. BMI levels did not show a significant difference in the first 6 months, but decreased significantly during the second 6 months of the study. Screen time, fast eating behavior, overeating behavior and food score index scores also demonstrated significant improvements during the intervention period of the study, between 6 and 12 months. It was concluded that nutrition and behavior education for the prevention and treatment of childhood obesity could be a successful intervention with close follow-up.

Efficacy and safety of JNJ-42165279, a fatty acid amide hydrolase inhibitor, in adolescents and adults with autism spectrum disorder: a randomized, phase 2, placebo-controlled study.

JNJ-42165279, a highly selective and orally bioavailable fatty acid amide (FAA) hydrolase inhibitor, was evaluated for efficacy and safety in adolescents and adults with autism spectrum disorder (ASD) in this phase 2, double-blind, placebo-controlled, multicenter study (NCT03664232). Participants aged 13-35 years, with a diagnosis of ASD (Diagnostic and Statistical Manual of Mental Disorders, 5th edition; Autism Diagnostic Observation Schedule, 2nd edition) were randomized (1:1) to 12 weeks of treatment with JNJ-42165279 (25 mg, twice-daily) or placebo. Primary endpoints were the change in the Autism Behavior Inventory (ABI) Core Domain (ABI-CD), ABI-Social Communication (ABI-SC), and ABI-Repetitive/Restrictive Behavior (ABI-RB) scores from baseline to day 85. Of the 61 participants (16 female, 45 male) included in the efficacy analyses, 53 (87%) completed the double-blind treatment. At day 85, the JNJ-42165279 group did not show a statistically significant reduction in ASD symptoms versus placebo, as assessed with ABI-CD (p = 0.284), ABI-SC (p = 0.290), and ABI-RB (p = 0.231). However, the following secondary outcomes exhibited small to moderate changes directionally favoring JNJ-42165279: Social Responsiveness Scale 2 (SRS, p = 0.064), Repetitive Behavior Scale-Revised (RBS-R, p = 0.006), Zarit Burden Interview short version (ZBI, p = 0.063), Child Adolescent Symptom Inventory-Anxiety (CASI-Anx, p = 0.048), and Caregiver Global Impression of Severity (p = 0.075). Notably, versus placebo, JNJ-42165279-treated participants showed increased concentrations of FAAs throughout the treatment period, with those achieving elevated concentrations experiencing the greatest reduction in the SRS total score at day 85. JNJ-42165279 demonstrated an acceptable safety profile. Although primary endpoints were not met, JNJ-42165279 may have a therapeutic effect on certain aspects of core ASD symptoms.

Effects of antenatal corticosteroids on outcomes of very premature infants and neurodevelopment during infancy

To explore the effects of antenatal corticosteroids (ACS) on the outcomes of very premature infants (VPIs) and neurodevelopment during infancy. A retrospective study was conducted on 190 VPIs admitted to the Department of Pediatrics of the First Affiliated Hospital of Anhui Medical University from January 2020 to December 2022. The infants were categorized into four groups based on ACS usage and dosage: no ACS group (n=18), single-course group (n=88), multi-course group (n=40), and partial-course group (n=44). The clinical outcomes, Neonatal Behavioral and Neurological Assessment (NBNA) scores at 40 weeks of corrected age, and Gesell Developmental Schedule (Gesell) scores at 1 year of corrected age were compared among the four groups. The impact of timing of ACS use on the Gesell scores of infants at 1 year of corrected age in VPIs with specific gestational ages was analyzed. The incidence rates of neonatal respiratory distress syndrome, bronchopulmonary dysplasia, transient tachypnea of the newborn, and neonatal pneumonia were significantly lower in the partial-course, single-course, and multiple-course groups compared with the no ACS group (P<0.008). However, there was no significant difference among the partial-course, single-course, and multiple-course groups (P>0.008). The NBNA scores (behavioral ability, active muscle tone, primitive reflexes, and general assessment) at 40 weeks of corrected age were significantly higher in the no ACS, partial-course, and single-course groups than in the multiple-course group (P<0.008). The proportion of VPIs with normal neurodevelopment at 1 year of corrected age was significantly higher in the no ACS, partial-course, and single-course groups than in the multiple-course group (P<0.008). The timing of ACS use had no significant effect on neurodevelopment at a corrected age of 1 year in infants with various gestational ages (P>0.05). ACS is crucial for the development of the respiratory system in VPIs, but multiple courses of ACS may cause neurodevelopmental abnormalities. The impact of ACS use on neurodevelopment is independent of gestational age and the timing of ACS use.

Factors associated with caregivers’ food safety knowledge, behavior, perception of food safety control, and the nutrition status of under-5 children in Nigeria

BackgroundHousehold-level food safety practices may have a long-term outcome on the nutrition and health status of under-five children. This study explores the relationships between caregivers’ self-reported food safety knowledge, behavior, perception of food safety control, and their young child’s (< 5 years) nutrition status.MethodsIn a cross-sectional study design, 664 caregivers from five Local Government Areas (LGAs) in Ibadan, Nigeria were surveyed using an interviewer-administered questionnaire on their food safety knowledge, behavior and perceived food safety control. Anthropometric measurements of the household’s index child (aged 6–59 months) were also taken. Variables for food safety knowledge and behavior score were selected using principal component analyses. The nutritional status of the children (Z-scores for weight-for-height (WAZ), height-for-age (HAZ), and weight-for-age (WHZ)) were calculated. Description statistics were run on all variables and logistic regression models examined associations between the three food safety constructs and the children’s nutritional status. Covariates such as LGAs, caregiver’s age, household size, wealth index, child’s gender, and age were adjusted.ResultsHigh-level of food safety knowledge, behavior and lots of perceived control on food safety issues were reported by 77.7%, 76.7%, and 81.1% of the caregivers. Using WAZ, HAZ and WHZ that are ≤ -2, acute malnutrition (6.0%), chronic malnutrition (42.5%), and underweight (22.0%), respectively were prevalent among the children. Perceived food safety control was the only food safety construct associated with acute malnutrition. Wealth index, caregivers’ age, number of under 5 at home, child age, and gender were associated with acute malnutrition. Caregiver’s age, child’s age, and gender were associated with chronic malnutrition. Furthermore, caregiver’s age, education and child’s age were associated with a child being underweight. The significance level was at P < 0.05.ConclusionFactors associated with food safety and children’s nutritional outcomes are multi-faceted in nature. Future studies should explore access to resources and other intermediate factors that may explain the linkage between childhood malnutrition and caregivers’ food safety awareness, knowledge, and behavior. Public health and food safety initiatives to bridge the gap between perceived food safety control and actual food safety behavior/practices.

The validity of studying healthy aging with cognitive tests measuring different constructs

A clinically useful characterization of the cognitive aging process requires the development of valid and robust behavioral tests, with an emphasis on explaining and understanding typical inter-individual variability in cognition. Here, using a dataset that includes behavioral scores collected with the National Institute of Health Toolbox Cognition Battery (NIHTB-CB) and other auxiliary tests, we examined (1) the differences between young and old adults across different cognitive domains, (2) the strength of across-subject correlations in behavioral test scores, (3) the consistency of low-dimensional behavioral representations across age using factor analysis, and (4) the accuracy of behavioral scores in predicting participants’ age. Our results revealed that (1) elderly females had better verbal episodic memory scores than elderly males, (2) across-subject correlations between behavioral tests varied with age group, (3) although a three-factor model explained the behavioral data in both age groups, some tasks loaded to different factors between the two groups, and (4) age-performance relationship (i.e. a regression model linking age to cognitive scores) in one group cannot be extrapolated to predict age in the other group, indicating an inconsistency in age-performance relationships across groups. These findings suggest that executive function tests might tap into different cognitive processes in different age groups, which might ultimately suggest that a statistically significant between-group difference in test performance might not always reflect differences in the same underlying cognitive processes. Overall, this study calls for more caution when interpreting age-related differences and similarities between age groups with different cognitive abilities even when the same tests are used.

Application effect of psychological counseling intervention based on WeChat platform in chemotherapy of gastrointestinal tumors with completely implanted venous infusion ports.

This study's objective was to observe the application effect of psychological counseling intervention based on the WeChat platform for patients with gastrointestinal tumors undergoing chemotherapy with completely implanted venous infusion ports. From October 2022 to December 2023, 110 patients with gastrointestinal tumors undergoing chemotherapy with completely implanted venous infusion ports were selected from our hospital. Patients were divided into 2 groups according to the different types of care. The control group received routine psychological counseling intervention, while the WeChat group received psychological counseling intervention based on the WeChat platform in addition to the routine intervention provided to the control group. A comparison was made between the 2 groups in terms of adverse events, compliance, hope level scores, and changes in coping strategy scores. The WeChat group experienced 7 adverse events, with an occurrence rate of 12.73%, while the control group experienced 17 adverse events, with an occurrence rate of 30.91%. The occurrence rate of adverse events in the WeChat group was significantly lower than that in the control group, showing a statistically significant difference (P < .05). The hope level scores before intervention in the 2 groups were compared (P > .05). Compared to before intervention, both groups showed an increase in scores for life attitude, proactive behavior, intimate relationships, and total scores. The WeChat group had higher scores after intervention compared to the control group (P < .05). The coping strategy scores before intervention in the 2 groups were compared (P > .05). Compared to before intervention, both groups showed an increase in facing scores and a decrease in avoidance and resignation scores (P < .05). After intervention, the WeChat group had higher facing scores and lower avoidance and resignation scores compared to the control group (P < .05). The overall chemotherapy compliance in the WeChat group was higher than that in the control group (P < .05). Psychological counseling intervention based on the WeChat platform can improve the level of hope, promote patients to face the disease with a positive attitude, increase chemotherapy compliance, and reduce the occurrence of adverse events in patients with gastrointestinal tumors undergoing chemotherapy with completely implanted venous infusion ports.

Maternal high-dose docosahexaenoic acid supplementation and neurodevelopment at 5 Years of preterm children

Background & AimsDocosahexaenoic acid (DHA) is the most abundant omega-3 fatty acid in the brain and is accumulated by the fetal brain during the last trimester of pregnancy. Our objective was to determine whether high-dose DHA supplementation during the neonatal period, vs. placebo, improves behavioral functioning at 5 years in children born very preterm. MethodsThis is a follow-up at 5 years corrected age of a subset of children who participated in a multicenter randomized controlled trial. The participants received a high-dose DHA supplementation, or a placebo, through maternal breast milk until 36 weeks’ postmenstrual age. Primary outcome was child behavioral functioning, assessed by the Total Difficulties Score from the Strengths and Difficulties Questionnaire (SDQ). Secondary outcomes included behavioral scores from the SDQ, executive functions assessment and global developmental performance. Neurodevelopmental outcomes were assessed through interviews with parents. Mean differences between DHA and placebo groups were estimated using mixed linear models. Subgroup analyses were conducted for sex and gestational age (GA) at birth. ResultsAmong 177 eligible children, 132 (74.6%) completed neurodevelopmental assessment at 5 years (DHA, N=64, placebo, N=68). Total Difficulties Score did not differ between the DHA and placebo groups (mean differences, -0.9 [95% confidence interval, -2.7 to 0.8], P=0.30), nor any of the secondary outcomes. There was no significant interaction between treatment groups and sex, nor GA, for the primary outcome. However, significant interactions between treatment groups and sex or GA were found for some secondary outcomes. ConclusionsIn very preterm infants, high-dose DHA supplementation did not improve behavioral functioning at 5 years.

Mode of delivery and behavioral and neuropsychological outcomes in children at 10 years of age.

Previous studies have reported that mode of delivery, particularly cesarean delivery (CD), is associated with neurodevelopmental outcomes in children. This study evaluates behavioral and neuropsychological test scores in children based on mode of delivery. Children enrolled in the Raine Study from Western Australia, born between 1989 and 1992 by instrumental vaginal delivery (IVD), elective CD, and non-elective CD, were compared to those with spontaneous vaginal delivery (SVD). The primary outcome was the Child Behavior Checklist (CBCL) administered at age 10. Secondary outcomes included evaluations of language, motor function, cognition, and autistic traits. Multivariable linear regression was used to evaluate score differences by mode of delivery adjusted for sociodemographic and clinical characteristics, and Poisson regression was used to evaluate for increased risk of clinical deficit. Of 2,855 children, 1770 (62.0 %) were delivered via SVD, 480 (16.8 %) via IVD, 346 (12.1 %) via elective CD, and 259 (9.1 %) via non-elective CD. Non-elective CD was associated with higher (worse) CBCL Internalizing (+2.09; 95 % CI 0.49, 3.96; p=0.01) scores, and elective CD was associated with lower (worse) McCarron Assessment of Neuromuscular Development (MAND) (-3.48; 95 % CI-5.61,-1.35; p=0.001) scores. Differences were not seen in other outcomes, and increased risk of clinical deficit was not observed with either the CBCL Internalizing or MAND scores. Differences in behavior and motor function were observed in children delivered by CD, but given that score differences were not associated with increased incidence of clinical deficit, clinical significance may be limited.

Adolescent risk behaviours are associated with educational attainment in early adulthood: results from the Raine Study cohort

BackgroundHigher educational attainment is important for economic wellbeing and associated with better health and longevity. Previous research focused on intelligence, socioeconomic status and mental health or individual risk behaviours as predictors of educational attainment, but the role of multiple domains of adolescent risk behaviours is less clear. This study examined the association between multiple domains of risk behaviour in adolescence and educational attainment by 22 years-of-age.MethodsYoung people (Generation 2, Gen2) and their parents (Generation 1, Gen1) participating in the Raine Study completed questionnaires at years 1, 5, 8, 10 (Gen1 only), 14, 17 (both) and 22 (Gen2 only). The Raine Study is an ongoing longitudinal study initiated in Perth, Western Australia, between 1989 and 1991. The 1,102 Gen2 participants who responded to questions about highest educational attainment were included in this study. The association between Gen2 self-reported risk behaviours (including age at commencement of drinking alcohol, smoking, sexual intercourse and drug use) and educational attainment (defined as self-reported years of completed high school: ≤10, 11, 12 or tertiary education (> 12)) at year 22, after adjusting for mother’s age and combined parental education level, participant sex, and family income, educational performance and adolescent mental health, was explored using ordinal regression models and presented as odds ratios (OR) with 95% confidence intervals (CI).ResultsOrdinal models suggested that never smoking or starting older than 18 compared with smoking before age 15 (OR 2.02, 95%CI: 1.28–2.14); first drinking alcohol between 15 and 17 years compared with younger than 15 (OR 1.52, 95%CI: 1.08–2.14); and, first sexual intercourse aged ≥ 18 years compared with under 15 (OR 1.67, 95%CI: 1.08–2.57) were associated with higher levels of educational attainment at 22-year follow-up. Additionally, lower (“better”) behavioural scores increased the odds of higher levels of attainment.ConclusionsAbsence of health risk behaviours at a younger age or later commencement was associated with higher educational attainment. Evidence-based interventions that address the societal influences underpinning risk behaviours in adolescents may support longer school retention.

Screening and Prediction of Autism in Toddlers Using SORF in Videos of Brief Family Interactions.

The purpose of this study was to validate the utility of the Systematic Observation of Red Flags (SORF) for autism screening during 10-minute parent-child interactions at ages 15-24 months. A total of 54 children participated in this study, including 19 with autism spectrum disorder (ASD), 23 with developmental delay, and 12 typically developing children. Coders coded 10-minute videos of parent-child interactions based on the defined scoring criteria. The discriminative ability for outcome diagnosis was evaluated for total score, social communication score, restricted repetitive behavior score, number of red flags, and composite score. SORF scores demonstrated good discriminative ability between ASD and non-ASD children, with the composite score (AUC = 0.884) showing the best discriminative ability for outcome diagnosis and predicting likelihood of ASD in young children. The composite score represented a simplified measurement, with the cutoff score of 7 and sensitivity and specificity of 0.789 and 0.800, respectively.

Impaired head circumference growth and behavioural problems in childhood: Longitudinal findings from the MINA-Brazil birth cohort.

Previous evidence on the relation between early head circumference (HC) growth and behavioural outcomes in preschoolers has been inconsistent. We aimed to investigate whether HC growth from birth to 5 years of age was related to internalising or externalising behavioural problems at 5 years of age in a sex-specific manner. Among 303 girls and 318 boys from the MINA-Brazil birth cohort, we examined the associations between changes in HC from birth to 5 years of age and internalising and externalising behaviour problem scores at 5 years according to the Strengths and Difficulties Questionnaire for parents. HC values were transformed into sex- and age-specific z-scores (HCZ) using World Health Organisation standards, and the differences between values at 5 years of age and birth were classified into quintiles. We estimated adjusted mean differences with 95% confidence intervals in behavioural problem scores between HCZ change quintiles using multivariable linear regression by sex. To examine nonlinear associations, we included cubic spline terms. Head circumference growth from birth to 5 years of age was inversely and nonlinearly associated with internalising problems in girls. Compared with girls at the lowest quintile of HC growth, those above had an adjusted 1.27 (95% confidence interval 0.28, 2.27) points lower mean internalising problems score. This association was mostly driven by HC growth during the first 2 years. We found no association between HC growth and externalising behaviour in either sex. Impaired HC growth was related to higher mean internalising problem scores at 5 years of age in girls but not in boys. HC growth was not associated with externalising problems.

Occupational exposure to organic solvents during pregnancy and child behavior from early childhood to adolescence

BackgroundOrganic solvents are used in formulating an extensive range of products for professional use. Animal and human studies suggest that in utero solvent exposure may affect neurodevelopment. Our objective was to assess the association between occupational exposure to solvents during pregnancy and child behavior aged 2–12 years.MethodsThe French mother-child cohort PELAGIE (2002–2006) included 3,421 women recruited in early pregnancy. Occupational exposure to solvents was self-reported. For 459 children, parents used a questionnaire derived from the Child Behavior Checklist and the Preschool Social Behavior Questionnaire to assess their child’s behavior, at age 2, and the Strengths and Difficulties Questionnaire at ages 6 and 12. A cross-lagged structural equation modeling approach was used to assess direct and indirect associations between exposure and child behavior.ResultsAt age 2, an increased externalizing behavior score was suggested with prenatal exposure to solvents (mean change in standardized score (95%CI): 0.28 (-0.01, 0.57) for occasional exposure and 0.23 (-0.05, 0.51) for regular exposure). At ages 6 and 12, distinct sex-specific patterns were observed: among boys, no association with externalizing behavior was observed, while among girls, an association was seen for both occasional and regular exposure (total effect at age 12: 0.45 (0.06,0.83) and 0.40 (0.03, 0.76), respectively). For both sexes, occasional exposure may be associated with internalizing behavior at ages 6 and 12 (total effect at age 6: 0.37 (0.06, 0.68) and at age 12: 0.27 (-0.08, 0.62)).ConclusionsOccupational exposure to solvents during pregnancy may impact child behavior through either direct or cumulative effects during childhood; these associations may persist until early adolescence, especially among girls.

Empowering Mothers: Self-efficacy Strategies and Fluoride Varnish Therapy Behavior in Preschool Children

Background: Oral health poses significant challenges, particularly among preschool children, emphasizing the critical role of mothers in preventive care. Self-efficacy, as a determinant of behavior, holds promise in shaping oral health practices. Objectives: The present study was conducted to determine the effect of Bandura's self-efficacy strategies on the fluoride varnish therapy behavior of mothers of preschool children. Methods: This intervention study, conducted from 2021 to 2023, involved 88 mothers with children aged 3 to 6 years. Participants were randomly divided into intervention and control groups. Data collection included a demographic questionnaire, a researcher-developed self-efficacy assessment tool, and an observational checklist of mothers' fluoride varnish therapy behavior. The intervention comprised educational sessions focusing on self-efficacy strategies. Data were analyzed with descriptive and inferential statistics in SPSS software version 20. Results: Before the intervention, there were no significant differences in self-efficacy scores between the intervention and control groups (Cohen's d = 0.18). Similarly, there were no significant differences between the two groups in the varnish therapy behavior score of the mother before the intervention (Cohen's d = 0.05). However, two months later, significant improvements were observed in both self-efficacy scores (Cohen's d = 2.28) and fluoride varnish therapy behavior (Cohen's d = 3/32) among mothers in the intervention group compared to controls. Conclusions: This study underscores the pivotal role of self-efficacy strategies in empowering mothers to effectively engage in fluoride varnish therapy behavior, and highlights the significant improvements observed in both self-efficacy and varnish therapy behavior that emphasize the educational interventions aimed at enhancing mothers' self-efficacy, ultimately contributing to improved oral health outcomes for children.

The reliability and validity of in-person and remote behavioural screening tools for people with amyotrophic lateral sclerosis

ObjectiveThis study aimed to assess the psychometric properties of and relationships between total scores on different screening tools assessing behavioural change for people with amyotrophic lateral sclerosis (ALS), and whether administering the screens as online questionnaires (rather than on paper, in-person) influences total scores. MethodsThe behavioural component of the Edinburgh Cognitive and Behavioural ALS Screen (ECASb); the behavioural component of the ALS Cognitive Behavioural Screen (ALS-CBSb), the ALS-Frontotemporal Dementia Questionnaire (ALS-FTD-Q), the Beaumont Behavioural Inventory (BBI), and the Motor Neuron Disease Behavioural Instrument (MiND-B) were administered to 35 informants on paper. Online questionnaire versions of the behavioural screens were administered to 49 informants.Forward stepwise linear regressions were conducted to assess whether scores on behavioural screens were predicted by scores on the other behavioural screens and to assess whether total scores were predicted by the mode of administration (paper or online) of the screens. ResultsBehavioural screening tools, except the ECASb, had good internal consistency but mixed item-total correlations. All regression models assessing whether behavioural screen scores predict other behavioural screen scores were significant. The BBI performed best and the ECASb performed worst in terms of their predictive relationships with other screening tools. The administration mode of the questionnaires did not significantly affect total scores. ConclusionsThe psychometric properties of the scales varied. The scales predicted each other's scores, supporting convergent validity. Online and paper versions performed similarly, and demographics did not predict scores.

Investigating the effect of peer-led educational intervention on behaviors related to pubertal health and its determinants in high school girls of Genaveh, Iran: Application of social cognitive theory

Background Empowering adolescents in the field of puberty health is one of the important goals of public health programs. The present study was carried out with the aim of determining the effect of peer-led training on puberty-related behavior and its determinants using social cognitive theory. Methods: A total of 245 teenage girls were randomly divided into two groups: the intervention group and the comparison group. The questionnaire measuring puberty-related behavior and its determinants was self-administered and completed before and 2 months after training in the two groups. One session for parents, four sessions for peer educators, and four sessions for participants were conducted for 1 month. Results: In the intervention group, unlike the comparison group, the mean scores of knowledge, outcome expectations, self-efficacy, self-control, social support, and behavior increased significantly after training (p <0.05). Based on regression analysis, outcome expectations and social support were the main determinants of puberty-related behavior (adjusted R2 = 0.464). Conclusion: The findings of this study support the effectiveness of the peer-led educational intervention based on social cognitive theory in the improvement of puberty-related behavior and its determinants, which can be used in the design of puberty-related health promotion programs. Further research to assess the longer-term outcomes and to examine other theories of behavior change are suggested.

Masticatory function and three-dimensional facial morphology of soft tissues: One year after orthognathic surgery

ObjectiveDentofacial deformities (DFD) require orthodontic treatment, orthognathic surgery, and speech therapy for aesthetic and functional problems. This longitudinal study analyzed changes in masticatory function and three-dimensional (3D) facial soft tissue in patients with Class II and Class III DFD after orthognathic surgery. In addition, the study investigated the relationship between facial measurements, maximum bite force (MBF), and orofacial myofunctional status (OMS). DesignThe sample consisted of 46 participants, including 10 patients with Class II DFD, and 11 patients with Class III DFD. These groups were assessed before (T0) and 6 months (T1) after surgery. Twelve patients who completed the treatment protocol were evaluated 12 months post-surgery (T2). The patient groups were compared with each other and with a control group (CG) of 25 healthy subjects. The participants underwent MBF and clinical evaluation of OMS, including masticatory behavior, using a validated protocol. The 3D facial soft tissue was assessed using laser scanning. ResultsCompared to the CG, DFD patients showed reduced MBF, masticatory behavior, and OMS scores at T0. At T2, there was an improvement in MBF, masticatory, and OMS scores, but differences were observed compared to the CG. Changes in facial soft tissue followed the underlying hard tissue movement resulting from surgery, and reduction of vertical measurements contributed to improvements in masticatory function. ConclusionThese findings indicated that combined surgery, orthodontic treatment, and speech therapy can lead to a significant improvement in masticatory function and facial soft tissue in DFD patients, although not completely 12 months post-surgery.

Impaired Reactive Control But Preserved Proactive Control in Hyperactive Children

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an “at risk” dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task, a revised Go/NoGo task, and the AX-continuous performance test (AX-CPT). Results: Children with higher levels of hyperactivity displayed: (1) significantly prolonged stop signal reaction time (SSRT) in the modified stop-signal anticipation task; (2) no notable differences in commission errors in the revised Go/NoGo task; (3) increased reaction time (RT) in stop-signal task and Go/NoGo task with increased probabilities of stop or NoGo signal; and (4) positive proactive behavioral index scores in AX-CPT. Conclusion: The results suggested that children with heightened hyperactivity exhibited impaired reactive control, especially for responses already underway, but preserved proactive control. Further studies concerning these children are warranted.

The Activation of PKM2 Induces Pyroptosis in Hippocampal Neurons via the NLRP3/Caspase-1/GSDMD Pathway in Neonatal Rats With Hypoxic-Ischemic Brain Injury.

The presence of hypoxic-ischemic brain damage (HIBD) in neonates triggers a strong neuroinflammatory reaction. Pyroptosis, a programmed cell death mechanism associated with inflammation, plays a crucial role in HIBD. Pyruvate kinase M2 (PKM2) plays a significant role in connecting metabolic processes and inflammatory responses, but whether it affects hippocampus pyroptosis in HIBD is unclear. The aim of this study is to elucidate the role of PKM2 in HIBD and to propose a novel therapeutic approach for neonatal ischemic-hypoxic encephalopathy. In this study, we employed neonatal 7-day-old Sprague Dawley rats to establish a model of HIBD using the Rice-Vannucci surgical technique and a hypoxia device. To inhibit the elevation of PKM2, we utilized the PKM2 inhibitor shikonin. The rats were categorized into four groups: Sham, Shikonin, HIBD, and Shikonin+HIBD. Behavioral tests, hematoxylin eosin staining, immunofluorescence staining, ELISA (IL-1β, IL-18), and LDH were conducted in each group to evaluate neurological function, hippocampal damage, the occurrence of neuronal pyroptosis, and the neuroinflammation. Western blot was used to assess the expression levels of PKM2, NLRP3, Caspase-1, Cleaved Caspase-1, GSDMD, GSDMDN, and IL-1β. The expression of PKM2 elevated in hippocampal tissues of the HIBD model and the localization of PKM2 in the hippocampus was activated in neurons instead of microglia during the HIBD. Meanwhile, the inhibition of PKM2 improved the behavioral test scores and the body weight of rats, the neuronal damage in the CA1 region of hippocampal tissue was also attenuated. In addition, inhibiting PKM2 alleviated neuronal pyroptosis by decreasing the expression of PKM2, NLRP3, Caspase-1, Cleaved Caspase-1, GSDMD, GSDMDN. Furthermore, serum levels of LDH and inflammatory factors IL-1β and IL-18 decrease with PKM2 inhibition. Based on these findings, we can conclude that PKM2 plays a crucial role in regulating hippocampal neuronal pyroptosis of HIBD rats via NLRP3/Caspase-1/GSDMD pathway. Therefore, inhibiting PKM2 could be a promising therapeutic strategy for the treatment of neonatal ischemic-hypoxic encephalopathy.

D-MHGCN: An End-to-End Individual Behavioral Prediction Model Using Dual Multi-Hop Graph Convolutional Network.

Predicting individual behavior is a crucial area of research in neuroscience. Graph Neural Networks (GNNs), as powerful tools for extracting graph-structured features, are increasingly being utilized in various functional connectivity (FC) based behavioral prediction tasks. However, current predictive models primarily focus on enhancing GNNs' ability to extract features from FC networks while neglecting the importance of upstream individual network construction quality. This oversight results in constructed functional networks that fail to adequately represent individual behavioral capacity, thereby affecting the subsequent prediction accuracy. To address this issue, we proposed a new GNN-based behavioral prediction framework, named Dual Multi-Hop Graph Convolutional Network (D-MHGCN). Through the joint training of two GCNs, this framework integrates individual functional network construction and behavioral prediction into a unified optimization model. It allows the model to dynamically adjust the individual functional cortical parcellation according to the downstream tasks, thus creating task-aware, individual-specific FCNs that largely enhance its ability to predict behavior scores. Additionally, we employed multi-hop graph convolution layers instead of traditional single-hop methods in GCN to capture complex hierarchical connectivity patterns in brain networks. Our experimental evaluations, conducted on the large, public Human Connectome Project dataset, demonstrate that our proposed method outperforms existing methods in various behavioral prediction tasks. Moreover, it produces more functionally homogeneous cortical parcellation, showcasing its practical utility and effectiveness. Our work not only enhances the accuracy of individual behavioral prediction but also provides deeper insights into the neural mechanisms underlying individual differences in behavior.
