A high index of suspicion is required to make a diagnosis of DS in children presenting with abnormal movement disorder and characteristic neuroimaging findings in a background of uncontrolled DM.

Role of inflammatory lipid and fatty acid metabolic abnormalities induced by plastic additives exposure in childhood asthma

Lipid metabolism play an essential role in occurrence and development of asthma, and it can be disturbed by phthalate esters (PAEs) and organophosphate flame retardants (OPFRs). As a chronic inflammatory respiratory disease, the occurrence risk of childhood asthma is increased by PAEs and OPFRs exposure, but it remains not entirely clear how PAEs and OPFRs contribute the onset and progress of the disease. We have profiled the serum levels of PAEs and OPFRs congeners by liquid chromatography coupled with mass spectrometry, and its relationships with the dysregulation of lipid metabolism in asthmatic, bronchitic (acute inflammation) and healthy (non-inflammation) children. Eight PAEs and nine OPFRs congeners were found in the serum of children (1 - 5 years old) from Shenzhen, and their total median levels were 615.16 ng/mL and 17.06 ng/mL, respectively. Moreover, the serum levels of mono-methyl phthalate (MMP), tri-propyl phosphate (TPP) and tri-n-butyl phosphate (TNBP) were significant higher in asthmatic children than in healthy and bronchitic children as control. Thirty-one characteristic lipids and fatty acids of asthma were screened by machine-learning random forest model based on serum lipidome data, and the alterations of inflammatory characteristic lipids and fatty acids including palmitic acids, 12,13-DiHODE, 14,21-DiHDHA, prostaglandin D2 and LysoPA(18:2) showed significant correlated with high serum levels of MMP, TPP and TNBP. These results imply PAEs and OPFRs promote the occurrence of childhood asthma via disrupting inflammatory lipid and fatty acid metabolism, and provide a novel sight for better understanding the effects of plastic additives on childhood asthma.

A Liquid Chromatography-Tandem Mass Spectrometry Method for Simultaneously Determining Meropenem and Linezolid in Blood and Cerebrospinal Fluid

Antibiotic therapy requires appropriate dosage of drugs for effective treatment. Too low antibiotic concentrations may lead to treatment failure and the development of resistant pathogens, whereas overdosing may cause neurological side effects or hemolytic diseases. Meropenem and linezolid are used only in the treatment of serious infections or when other antibiotics are no longer effective as well as for treating central nervous system infections. It is difficult or sometimes even impossible to predict the relation between dosing of antibiotics and its cerebrospinal fluid (CSF) concentration; thus, a method of determining antibiotics not only in the blood but also in the CSF is needed. Analytical method validation is an integral part of good laboratory practice and ensures high accuracy of the results. We performed complete validation process according to the Food and Drug Administration and European Medicine Agency, covering the aspects precision, specificity, accuracy, recovery, limit of detection, limit of quantification, stability, carry-over, and matrix effects. Our liquid chromatography-tandem mass spectrometry method for the simultaneous measurement of meropenem and linezolid in different matrix meets all the acceptance criteria. The method was successfully applied to determine meropenem and linezolid concentrations in serum and CSF samples obtained from children treated with these antibiotics.

Parental involvement affects parent-adolescents brain-to-brain synchrony when experiencing different emotions together: An EEG-based hyperscanning study

Parental involvement (PI) is a broad and multifaceted construct, which refers to the parental demonstration of interest in their child, caring, and warmth (Davis et al., 2021). Parental involvement affects parent-adolescent's relationship and communication. However, there was little research to examine the underlying neural mechanism. The present study aimed to explore how parental involvement is associated with the brain-to-brain synchronous activation between parent-adolescent dyads when sharing emotional experience together by using the electroencephalograph (EEG) hyperscanning. EEG was recorded simultaneously in a sample of 26 parent-adolescent dyads (Mparents'age=43.312, SD=5.468; Madolescents' age=12.077, SD=1.412) when completing the picture processing task. Phase locking values (PLVs) in beta band and gamma band were used to compare the differences in the parent-adolescent dyads' induced brain-to-brain synchrony between the high parental involvement group (HPI) and the low parental involvement group (LPI). Results showed that greater beta brain-to-brain synchrony was observed in the HPIs than in the LPIs when experiencing positive emotions together in the central region. However, there was no significant difference between the HPIs and the LPIs in the negative and neutral condition. Moreover, greater gamma brain-to-brain synchrony was observed when viewing negative emotional stimuli together than viewing positive emotional stimuli together in the LPIs in the central region. However, there was no significant difference between different emotional conditions in the HPIs. Findings of the present study provide neuroscientific evidence that parental involvement may strengthen parent-adolescent's emotional interaction and communication.

Self-esteem and cortical thickness correlate with aggression in healthy children: A surface-based analysis

Aggressive behavior can have serious physical, psychological, and social consequences. However, little is known about the personality and neurological antecedents underlying aggressive behavior in children. The objective of this study was to investigate the relationship between self-esteem, aggression, and brain structure (i.e., cortical thickness and surface area) in a population of healthy children (N = 78; 9-12 years; mean age: 9.95 ± 0.90 years). The results revealed that self-esteem showed a negative association with aggression and significantly predicted aggressive behavior. No gender differences were found in aggression and its neural correlates. We performed the cortical parcellation method to further explore the neural foundations underlying the association of self-esteem with aggression. Children with higher aggression had increased cortical thickness in four clusters after multiple comparison correction: right medial orbitofrontal cortex, right lateral orbitofrontal cortex, right superior frontal gyrus, and left insula. In a mediation analysis, cortical thickness in the right medial orbitofrontal cortex contributed to the effect of self-esteem on aggression. These findings extend our understanding of morphological correlates of aggression in children, suggesting that an increased cortical thickness in childhood is a potential mechanism linking low self-esteem to aggression.

Prenatal exposure to per- and polyfluoroalkyl substances and DNA methylation in the placenta: A prospective cohort study

Epidemiological studies regarding the relationship between per- and polyfluoroalkyl substances (PFAS) and DNA methylation were limited. We investigated the associations of maternal PFAS concentrations with placental DNA methylation and examined the mediating role of methylation changes between PFAS and infant development. We measured the concentrations of 11 PFAS in maternal plasma during early pregnancy and infant development at six months of age. We analyzed genome-wide DNA methylation in 16 placental samples using reduced representation bisulfite sequencing. Additionally, we measured DNA methylation levels using bisulfite amplicon sequencing in 345 mother-infant pairs for five candidate genes, including carbohydrate sulfotransferase 7 (CHST7), fibroblast growth factor 13 (FGF13), insulin receptor substrate 4 (IRS4), paired like homeobox 2Ap (PHOX2A), and plexin domain containing 1 (PLXDC1). We found that placental DNA methylation profiles related to PFOA mainly enriched in angiogenesis and neuronal signaling pathways. PFOA was associated with hypomethylation of IRS4 and PLXDC1, and PFNA was associated with PLXDC1 hypomethylation. There were positive associations of CHST7 methylation with PFTrDA and IRS4 methylation with PFDoA and PFTrDA. PLXDC1 hypomethylation mediated the association between PFOA and suspected developmental delay in infants. Future studies with larger sample sizes are warranted to confirm these findings.

Identification of novel NRF2-dependent genes as regulators of lead and arsenic toxicity in neural progenitor cells

Lead (Pb) and arsenic (As) are prevalent metal contaminants in the environment. Exposures to these metals are associated with impaired neuronal functions and adverse effects on neurodevelopment in children. However, the molecular mechanisms by which Pb and As impair neuronal functions remain poorly understood. Here, we identified F2RL2, TRIM16L, and PANX2 as novel targets of Nuclear factor erythroid 2-related factor 2 (NRF2)-the master transcriptional factor for the oxidative stress response-that are commonly upregulated with both Pb and As in human neural progenitor cells (NPCs). Using a ChIP (Chromatin immunoprecipitation)-qPCR assay, we showed that NRF2 directly binds to the promoter region of F2RL2, TRIM16L, and PANX2 to regulate expression of these genes. We demonstrated that F2RL2, PANX2, and TRIM16L have differential effects on cell death, proliferation, and differentiation of NPCs in both the presence and absence of metal exposures, highlighting their roles in regulating NPC function. Furthermore, the analyses of the transcriptomic data on NPCs derived from autism spectrum disorder (ASD) patients revealed that dysregulation of F2RL2, TRIM16L, and PANX2 was associated with ASD genetic backgrounds and ASD risk genes. Our findings revealed that Pb and As induce a shared NRF2-dependent transcriptional response in NPCs and identified novel genes regulating NPC function. While further in vivo studies are warranted, this study provides a novel mechanism linking metal exposures to NPC function and identifies potential genes of interest in the context of neurodevelopment.

Biomonitoring of glyphosate and aminomethylphosphonic acid: Current insights and future perspectives

Glyphosate is one of the most widely used herbicides globally, raising concerns about its potential impact on human health. Biomonitoring studies play a crucial role in assessing human exposure to glyphosate and providing valuable insights into its distribution and metabolism in the body. This review aims to summarize the current trends and future perspectives in biomonitoring of glyphosate and its major degradation product of aminomethylphosphonic acid (AMPA). A comprehensive literature search was conducted, focusing on studies published between January 2000 and December 2022. The findings demonstrated that glyphosate and AMPA have been reported in different human specimens with urine as the dominance. Sample pretreatment techniques of solid-phase and liquid-liquid extractions coupled with liquid/gas chromatography-tandem mass spectrometry have achieved matrix elimination and accurate analysis. We also examined and compared the exposure characteristics of these compounds among different regions and various populations, with significantly higher levels of glyphosate and AMPA observed in Asian populations and among occupational groups. The median urinary concentration of glyphosate in children was 0.54 ng/mL, which was relatively higher than those in women (0.28 ng/mL) and adults (0.12 ng/mL). It is worth noting that children may exhibit increased susceptibility to glyphosate exposure or have different exposure patterns compared to women and adults. A number of important perspectives were proposed in order to further facilitate the understanding of health effects of glyphosate and AMPA, which include, but are not limited to, method standardization, combined exposure assessment, attention for vulnerable populations, long-term exposure effects and risk communication and public awareness.

Methylphenidate exposure in juvenile period elicits locomotion changes and anxiolytic-like behavior in adulthood: Evidence using zebrafish as a translational model

Methylphenidate (MPH) is a central nervous system stimulant that is mainly used for Attention-Deficit/Hyperactivity Disorder (ADHD). It is well known that there is a high rate of ADHD misdiagnosis, leading to a great number of neurotypical children chronically exposed to MPH in early periods of life. This increase raises concern about possible long-lasting effects of this exposure. We aimed to evaluate whether exposure to MPH during childhood might impact adult behavioral pattern. For this purpose, we used zebrafish as a translational model considering its robustness as experimental model and fast life cycle. Fish were exposed during juvenile period (from 30 to 60 post-natal day) at MPH therapeutic concentration (2 mg L-1), and behavioral tests were performed at fish adulthood (120 post-natal day). MPH provoked slight anxiolytic-like effects and hyperlocomotion, and no differences on sociability and cortisol levels were observed. Moreover, sex did not affect any of the parameters evaluated. These results demonstrate that early chronic exposure to MPH leads to neurobehavioral adaptations that persist into adulthood in zebrafish regardless of sex, suggesting that the misuse of MPH during childhood and adolescence can alter neurobehavioral plasticity and these alterations might persist until adulthood.

Artificial Intelligence in Pediatric Urology

Application of artificial intelligence (AI) is one of the hottest topics in medicine. Unlike traditional methods that rely heavily on statistical assumptions, machine learning algorithms can identify highly complex patterns from data, allowing robust predictions. There is an abundance of evidence of exponentially increasing pediatric urologic publications using AI methodology in recent years. While these studies show great promise for better understanding of disease and patient care, we should be realistic about the challenges arising from the nature of pediatric urologic conditions and practice, in order to continue to produce high-impact research.

Surgical Management of Velopharyngeal Dysfunction

Velopharyngeal dysfunction (VPD) is caused by inadequate closure of the velopharyngeal port. VPD can hinder a child's ability to communicate and can impact his/her quality of life. Evaluation of children with VPD is often completed in a multidisciplinary setting and often involves studies that allow for the visualization of the velopharyngeal closure during voluntary speech (ie, nasopharyngoscopy). Multiple surgical options exist for the treatment of VPD including pharyngeal flap, sphincter pharyngoplasty, buccal myomucosal flaps, Furlow palatoplasty, palate re-repair, intravelar veloplasty, and injection pharyngoplasty. Each speech surgery has its unique benefits and drawbacks and the decision on which surgery to recommend should be tailored to each patient's specific needs and weighing the risk/benefit profile for their specific surgeries.

Pediatric Craniomaxillofacial Fractures: A Review

Pediatric facial fractures constitute a small portion of all facial fractures. The frequency of pediatric facial fractures by location, and mechanism of injury, changes over time associated with craniofacial growth and activity. Pediatric patients have protective anatomic features, such as increased soft tissue, excess adipose tissue, and more flexible bone. Conservative management is often sufficient. Surgical intervention can often be conservative. Follow-up monitoring is valuable for concerns of growth disruption from either the trauma itself or surgical interventions. Older teenage patients may often be treated similar to adults. Postoperative management varies by fracture type without a defined long-term follow-up course.

Pre-pandemic adversity and maternal mental health during the COVID-19 pandemic: the mediating role of pandemic stress and family relationships

BACKGROUND

The COVID-19 pandemic was a time of increased stress for families. Parents with a history of adversity may have been at higher risk of experiencing mental health problems during this time. The current study aims to investigate the relationship between pre-pandemic adversity pandemic related stressors and maternal mental health outcomes during the pandemic.

METHODS

Data was drawn from the Mothers' and Young People's Study (MYPS), a longitudinal of first time mothers and their children. Participants were 418 mothers who completed the MYPS COVID-19 sub-study. Data was collected during pregnancy, at 1, 4, 10 years postpartum, and during the COVID-19 pandemic (approximately 14 years postpartum). Path-analysis was used to test the relationship indirect relationship between pre-pandemic adversity and maternal depressive and anxiety symptoms, via family functioning and pandemic related stress.

RESULTS

The hypothesised model was a good fit to the data accounting for 34 % and 33 % of the variance in maternal depressive and anxiety scores, respectively. A significant indirect effect was found between pre-pandemic adversity and both maternal anxiety and depressive systems via family relationships during the pandemic and pandemic related stress.

LIMITATIONS

MYPS participants who took part in the COVID-19 sub-study were more likely to be older, have a higher level of education, and speak English as a first language, compared to the total MYPS sample.

CONCLUSIONS

Family inclusive service responses which aim to strengthen family relationships may be particularly important for families where there is a history of adversity to support parental mental health.

Triggered by worry: A dynamic network analysis of COVID-19 pandemic-related anxiety and parental stress

BACKGROUND

Major disruptions to daily life routines made families and parents particularly vulnerable to psychological distress during the COVID-19 lockdowns. However, the specific psychopathological processes related to within-person variation and maintenance of anxiety symptomatology and parental distress components in the parental population have been largely unexplored in the literature.

METHODS

In this preregistered intensive longitudinal study, a multilevel dynamic network was used to model within-person interactions between anxiety symptomatology, psychopathological processes, parental distress, and protective lifestyle components in a sample of 495 parents-each responding to daily assessments over a 40-day period. A total of 30,195 observations were collected across the subjects.

RESULTS

Extensive worry, threat monitoring, and uncontrollability of worry were identified as overreaching psychopathological processes related to the aggravation of other symptoms of anxiety and parental distress. A strong association was found between parental stress and parental burnout. Anger toward one's child was associated with both parental stress and parental burnout. Protective factors showed the lowest strength centrality, with few and weak connections to other symptoms and processes in the network.

LIMITATIONS

Associations may exist between the study variables on a different time scale; hence, different time lags should be used in future research.

CONCLUSIONS

Accessible, low-cost interventions that address worry, threat monitoring, and the uncontrollability of worry could serve as potential targets for reducing the symptom burden of anxiety and distress in the parental population.

The successful use of a search strategy improves with visuospatial working memory in 2- to 4.5-year-olds

Using spatial cues such as shape, orientation, and pattern aids visuospatial working memory because it allows strategies that reduce the load on this cognitive resource. One such strategy, namely taking advantage of patterned spatial distributions, remains understudied to date. This strategy demands keeping track of already-searched locations and excluding them from further search and so correlates with visuospatial working memory. The use of such strategies should, in principle, develop in early childhood, but because most studies focus on chunking, the development of other strategies reducing the load on working memory is understudied in young children. Therefore, in this study we tested whether children aged 2 to 4.5 years (N = 97) could take advantage of spatial cues in their search and whether this ability correlated with their age, verbal ability, and visuospatial working memory. The results showed that the ability to use a patterned spatial distribution (searching a row of locations from one side to the other instead of a random search) significantly improved with visuospatial working memory but not with age or verbal ability. These results suggest that visuospatial abilities may rapidly develop from 2 to 4.5 years of age, and given their impact on later mathematic achievement, demand increased attention in cognitive developmental research and early childhood education.

The relation between effortful control and executive function training in preschoolers

In recent years, the question of whether executive function (EF) is malleable has been widely documented. Despite using the same training tasks, transfer effects remain uncertain. Researchers suggested that the inconsistency might be attributed to individual differences in temperamental traits. In the current study, we investigated how effortful control, a temperamental trait, would affect EF training outcomes in children. Based on parent rating, 79 6-year-old preschoolers were identified as having higher or lower effort control and were assigned to three conditions: working memory (WM) training, inhibitory control (IC) training, and a business-as-usual control group. Children completed assessments at baseline, 1 week after intervention (posttest), and 3 months after intervention (follow-up). As compared with the control group, the WM and IC training groups showed improvement in both trained tasks and nontrained measures. At baseline, children with higher effortful control scores showed greater WM capacity and better IC. Furthermore, effortful control was positively correlated with training gain in both training groups, with children with higher effortful control benefitting more through training. In the WM training group, effortful control was positively correlated with near transfer on WM outcomes both immediately and longitudinally. At posttest, the WM and IC training groups showed a positive correlation between effortful control and fluid intelligence performance. Our results underscore the importance of individual differences in training benefits, in particular the role of effortful control, and further illustrate the potential avenues for designing more effective individualized cognitive training programs to foster learning and optimize children's development.

Everyday Ethics in Ambulatory Pediatrics: Cases and Applications

This article presents three clinical scenarios that might be encountered in ambulatory pediatrics. The framework for ethical analysis presented by Dr Hughes in a separate article in this issue of the Journal is used to examine these clinical scenarios and demonstrate application of the framework. The three cases involve a physician being asked by parents to write a letter for better housing that would require the doctor to be dishonest; parents who decline to have their 8-month-old daughter vaccinated; and a physician who believes contraception is a sin and therefore would not prescribe it to a sexually active 17-year-old girl.

Association of air pollution exposure with overweight or obesity in children and adolescents: A systematic review and meta-analysis

Childhood overweight and obesity is a global problem. 38 million children under five years old were reported as being overweight/obese in 2019. However, current evidence regarding the effects of air pollution on children weight status remains scarce and inconsistent. This study aimed to determine the association between air pollutants and the weight status of children and adolescents. Four databases were searched up to August 9, 2023. Adjusted merged odds ratios (ORs), regression coefficients (β), and their 95 % confidence intervals (95 % CIs) were calculated and pooled. A total of 27 studies were included. The results showed that air pollutants had adverse effects on the body weight of children and adolescents. Exposure to PM1, PM2.5, PMcoarse, and PM10 were associated with increased risk of overweight/obesity, with pooled ORs (95 % CI) of 1.23 (1.09, 1.40), 1.18 (1.10, 1.28), 1.04 (1.03, 1.05) and 1.11 (1.06, 1.17) per 10 μg/m3 increment, respectively. Individuals with higher exposure levels to NOX, O3, SO2 and CO (per 10 μg/m3 increment) were associated with 12 %, 6 %, 28 % and 1 % increased odds of being overweight/obese, respectively. With respect to the level of body mass index, the pooled β (95 % CIs) for each 10 μg/m3 increase in PM1, PM2.5, PM10, and NOX exposure were 0.15 (0.12, 0.18), 0.11 (0.06, 0.16), 0.07 (0.03, 0.10), and 0.03 (0.01, 0.04), respectively. PM1 has relatively strong adverse effects on body weight status. The subgroup analysis revealed a significantly increase in the risk of overweight/obesity when the concentrations of PM2.5, PM10, and NO2 exceeded 35 μg/m3, 50 μg/m3, and 40 μg/m3, respectively. Exposure to PM2.5, PM10 and NOX increased the risk of overweight/obesity, especially in Asia. This study provides evidence of the association between air pollution and being overweight/obese in children and adolescents.

Consent and Assent in Pediatric Research

Research involving pediatric populations has important ethical and regulatory considerations. As children generally cannot consent to research, there are special protections put in place to ensure that the decisional vulnerability is protected, including parental permission and often the child's assent. Assent is an ethically important part of the research because it allows the child to participate in the process of agreeing to research, develop their autonomy, and express their values. This article explores a case where the child and parent disagree about the child's participation. In doing so, the regulatory requirements of pediatric research are outlined and the process and product of obtaining assent from a minor is described.

Playing hide and seek: Contextual regularity learning develops between 3 and 5 years of age

The ability to acquire contextual regularities is fundamental in everyday life because it helps us to navigate the environment, directing our attention where relevant events are more likely to occur. Sensitivity to spatial regularities has been largely reported from infancy. Nevertheless, it is currently unclear when children can use this rapidly acquired contextual knowledge to guide their behavior. Evidence of this ability is indeed mixed in school-aged children and, to date, it has never been explored in younger children and toddlers. The current study investigated the development of contextual regularity learning in children aged 3 to 5 years. To this aim, we designed a new contextual learning paradigm in which young children were presented with recurring configurations of bushes and were asked to guess behind which bush a cartoon monkey was hiding. In a series of two experiments, we manipulated the relevance of color and visuospatial cues for the underlying task goal and tested how this affected young children's behavior. Our results bridge the gap between the infant and adult literatures, showing that sensitivity to spatial configurations persists from infancy to childhood, but it is only around the fifth year of life that children naturally start to integrate multiple cues to guide their behavior.

Rapport building with adolescents to enhance reporting and disclosure

Adolescents comprise a vulnerable population that is exposed to crime and also may be reluctant to disclose full details of their experiences. Little research has addressed effective ways of increasing their willingness to disclose and provide complete reports. Strategies that improve honesty and report completeness in other age groups have not been evaluated to determine whether they are similarly effective at increasing adolescents' reporting. In the current study, we tested whether rapport building techniques, modified from those commonly used with children and adults to address reasons why adolescents are likely reluctant, enhance the amount of detail adolescents provide about prior experiences. The participants, 14- to 19-year-olds (N = 125), completed an online questionnaire regarding significant events (e.g., big argument with family member) they experienced during the last 12 months. After a delay, they completed a remote interview asking them to recount details of one of the events. The interview began with either standard rapport building composed of largely yes/no questions about the adolescents' background or one of two expanded rapport building phases: open-ended (questions about the adolescents' backgrounds that required narrative answers) or enhanced (open-ended questions paired with the interviewer also sharing personal information). Although only adolescents in the standard condition showed age-related increases in information disclosed, overall adolescents in the enhanced condition provided significantly longer and more detailed narratives than adolescents in the other conditions. This effect was largest for the youngest adolescents, suggesting that mutual self-disclosure may be especially beneficial for eliciting honest complete reports from adolescents about salient prior experiences.

Inequity in Cancer and Cancer Care Delivery in the United States

Inequity exists along the continuum of cancer and cancer care delivery in the United States. Marginalized populations have later stage cancer at diagnosis, decreased likelihood of receiving cancer-directed care, and worse outcomes from treatment. These inequities are driven by historical, structural, systemic, interpersonal, and internalized factors that influence cancer across the pathologic and clinical continuum. To ensure equity in cancer care, interventions are needed at the level of policy, care delivery, interpersonal communication, diversity within the clinical workforce, and clinical trial accessibility and design.

The role of perinatal maternal symptoms of depression, anxiety and pregnancy-specific anxiety for infant's self-regulation: A prospective longitudinal study

BACKGROUND

Maternal symptoms of anxiety and depression are highly prevalent during pregnancy and postpartum and have the potential to impact fetal development and offspring behavior. However, research on the effects of fetal exposure to maternal subclinical affective symptoms on infant self-regulation is still lacking. Self-regulation provides a fundamental precondition for healthy development and overall life success whereas dysfunctional self-regulation can lead to behavioral problems, poor academic achievement, social rejection, and physical/mental disorders. During pregnancy and infancy, children largely depend upon their mothers in order to successfully regulate their internal states. Given the high prevalence of mothers suffering from anxiety and depressive symptoms during pregnancy and after childbirth, the aim of the present study is to explore how maternal affective symptoms change during the pre- and postnatal period, and how measures obtained in pregnancy and beyond impact self-regulation in infants, as indicated by crying-, sleeping-, and/or feeding problems.

METHODS

This prospective longitudinal study investigates the effects of maternal symptoms of depression, anxiety, and pregnancy-specific anxiety on infant's self-regulation in N = 225 mother-infant dyads. Maternal affective symptoms were examined at five prenatal and three postnatal time-points using the Edinburgh Postnatal Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI) and the Pregnancy Related Anxiety Questionnaire Revised (PRAQ-R2). Infant's self-regulation was assessed twice - at the age of three and six months - using the Crying Feeding Sleeping Scale (SFS).

RESULTS

Maternal pregnancy-specific anxiety was the most significant predictor for infant self-regulatory problems. It predicted crying-, sleeping, and feeding problems and explained up to 18 % of the variance. Even when controlling for maternal postpartum affective symptoms, pregnancy-specific anxiety remained a significant predictor for infant self-regulation problems.

LIMITATIONS

Rather homogenous sample (high socioeconomic status). Data based on maternal reports of infant behavior.

CONCLUSIONS

Our results suggest that fetal exposure to maternal affective symptoms - specifically pregnancy-related anxiety - plays a substantial role in the development of infant self-regulation problems, potentially mediated by epigenetic modifications. Importantly, even though maternal symptoms of depression and anxiety only reached subclinical levels, they were predictive for infant crying-, sleeping-, and feeding problems. Our findings underline the importance of early prevention and clearly tailored interventions during pregnancy and postpartum to prevent adverse outcome for mother, child and family.

The mediating role of childhood maltreatment in the association between residence migration and adolescent depression

BACKGROUND

It is well established that residence migration can negatively affect the mental health of adolescents. However, the related factors that mediate the association between residence migration and depression are still uncertain.

METHODS

The participants were 16,037 adolescents in junior middle schools. A self-administered questionnaire was used for the survey. In addition to collecting general demographic characteristics of the participants, including age, gender, local residence status, only child status, parental marriage status and parent-child relationship, the questionnaire also contained the 9-item Patient Health Questionnaire, the short form of the Childhood Trauma Questionnaire and the Connor-Davidson Resilience Scale. Data analysis was conducted using SPSS software.

RESULTS

A total of 14,059 valid questionnaires were collected, resulting in 12,122 local adolescents, defined as being born and raised locally, and 1937 migrant adolescents, defined as being transferred from other regions. Meanwhile, 53.3 % of local adolescents and 58.2 % of migrant adolescents reported depressive symptoms. This result indicated that residence migration might contribute to depression symptoms(OR = 1.136, 95%CI: 1.013-1.273, p < 0.05). Childhood maltreatment and parental divorce are risk factors for depression in migrant adolescents. For all adolescents, resilience and a good parent-child relationship may reduce the risk of depression. Childhood maltreatment completely mediates residence migration-related depression(95 % bootstrap CI = 0.146, 0.323).

CONCLUSION

This study revealed that residence migration could contribute to adolescent depression, and childhood maltreatment may largely mediate this process, providing new insight into the relationship between adolescent depressive symptoms and residence migration. Reducing childhood maltreatment may effectively improve the depressive symptoms of migrant adolescents.

Identification of central symptoms of children depression and development of two short version of Children's Depression Inventory: Based on network analysis and machine learning

BACKGROUND

Using network analysis to study the central symptoms is important for understanding the mechanism of depression symptoms and selecting items for the short version depression screening scale. This study aimed to identify the central symptoms of depression and develop the short and effective depression screening tools for Chinese rural children.

METHODS

Firstly, the 2458 individuals (Mage = 10.74; SDage = 1.64; 51.2 % were female) were recruited from the rural children's mental health database. Children's Depression Inventory (CDI) was used to assess depression symptoms. Then, network analysis was used to identify the central symptoms of depression. The accuracy, stability, and gender invariance of the depression symptoms network were tested. Finally, a short version of CDI with central symptoms (CDI-SC) and a new CDI-10 (CDI-10-N) were developed by network analysis and feature selection techniques to optimize the existing CDI-10. Their performances in screening depression symptoms were validated by the cutoff threshold and machine learning.

RESULTS

The central symptoms of Chinese rural children's depression were sadness, self-hatred, loneliness and self-deprecation. This result was accurate and stable and depression symptoms network has gender invariance. The AUC values of CDI-10-N and CDI-SC are over 0.9. The CDI-10-N has a higher AUC than CDI-10. The optimal cutoff thresholds for CDI-10-N and CDI-SC are 6 and 1. The performance of machine learning on AUC generally outperforms those of cutoff threshold.

CONCLUSIONS

The central symptoms identified in this study should be highlighted in screening depression symptoms, and CDI-10-N and CDI-SC are effective tools for screening depression symptoms in Chinese rural children.

Nonsyndromic Craniofacial Disorders

We describe the investigation and management of select pediatric craniofacial disorders their recent advances. Positional plagiocephaly: The incidence of positional plagiocephaly has increased since the institution of the "safe to sleep" campaign to reduce sudden infant death syndrome. Positional plagiocephaly may be associated with underlying developmental delay. Nonsyndromic craniosynostosis: Treatment of nonsyndromic craniosynostosis depends on the age of the patient and the suture involved. Pediatric skull lesions: Management of skull lesions depends on histologic diagnosis. Some benign skull lesions are managed conservatively, whereas erosive and malignant lesions may require surgical excision, radiotherapy, chemotherapy, or multimodality treatment.
