BACKGROUND Orientation to bodily signals reflects the ways in which individuals interpret their bodily sensations. Such orientation is formed within early interpersonal context. Findings reveal that trauma may result in catastrophic and fearful orientation towards bodily signals. However, not much is known regarding the link between trauma and orientation towards the body as manifested within a family intergenerational context. OBJECTIVE This study examines the link between child maltreatment, complex posttraumatic stress symptoms (CPTS symptoms), and a posttraumatic orientation to bodily signals among dyads of mothers and their young adult daughters. PARTICIPANTS AND SETTING 194 mother-daughter dyads (mothers' mean age = 56, SD = 6.3; daughters' mean age = 26, SD = 3.03) completed self-reported questionnaires, assessing child maltreatment (CTQ), CPTS symptoms (ITQ), and orientation to bodily signals (pain catastrophizing, anxiety sensitivity-physical, body vigilance). RESULTS Orientation to bodily signals was associated with child maltreatment, through the mediation of CPTS symptoms among mothers (indirect effects between 0.13-0.28; p > 0.021) and daughters (indirect effects between 0.21-0.11; p > 0.032). Mothers' child maltreatment was associated with daughters' child maltreatment (effect = 0.35; p less then 0.001), and mothers' orientation to bodily signals was associated with daughters' orientation (effects between 0.19-0.27; p less then 0.016). Daughters' orientation to bodily signals was partially associated with mothers' child maltreatment through mothers' CPTS symptoms and orientation to body (indirect effect = 0.064; p = 0.023). CONCLUSIONS Child maltreatment is implicated in posttraumatic orientation towards bodily signals. Such secondary processes may be intergenerationally transmitted. BACKGROUND Despite the number of studies showing the link between maternal adverse childhood experiences (ACEs) and offspring's neural development and mental health, little is known about the impacts of maternal ACEs on offspring's academic performance in the adolescent period. OBJECTIVE To examine the associations between maternal ACEs and self-rated academic performance in adolescent offspring. PARTICIPANTS AND SETTING Data from the population-based Kochi Child Health Impact of Living Difficulty (K-CHILD) study, conducted in 2016, was analyzed. Participants included 10,810 children in fifth grade, eighth grade, and eleventh grade living in Kochi prefecture, Japan, and data from maternal respondents were used (n = 7964). METHODS Maternal ACEs, childhood social economic status, current mental health, current socioeconomic status and maternal maltreatment of child were assessed by mothers. Self-rated academic performance was reported by children using a 5-point Likert scale. Ordinal logistic regression analyses were performed, which excluded children with lower self-esteem to avoid measurement bias on self-rated academic performance due to low self-esteem. RESULTS A higher number of maternal ACEs had a dose-response relationship with lower self-rated academic performance in adolescent offspring after adjusting for confounder (p trend less then 0.001). Specifically, adolescents of mothers who experienced parent loss were more likely to report lower self-rated academic performance (OR = 1.31; 95 %CI = 1.16-1.47), whereas adolescents of mothers who experienced maltreatment in childhood showed no association (OR = 1.10, 95 %CI = 0.99-1.22). CONCLUSIONS Maternal ACEs, and especially maternal parent loss, were associated with lower self-rated academic performance in adolescent offspring. Further study is needed to elucidate the possible mechanism underlying this association. BACKGROUND Child maltreatment reports (CMR) are both common and strongly associated with various negative outcomes. OBJECTIVE To examine CMR risks by child age, early childhood context, current/cumulative economic status (welfare receipt), race, and other risk factors with a longitudinal dataset. PARTICIPANTS AND SETTING The CAN sample included 2,111 children having a CMR ≤ age 3, suggestive of a harmful early childhood context. The AFDC sample included 1,923 children having AFDC but no CMR ≤ age 3, suggestive of early childhood protective factors despite poverty. METHODS We estimated the CMR likelihood at each age from 1-17 years based on various risk factors while following up children from 1995-2009. RESULTS During follow-up, CMR likelihoods were substantially higher for the CAN sample than for the AFDC sample. The age-CMR relationship was strongly negative for the CAN sample (OR = 0.87, 95% CI = 0.86-0.88). This relationship was weaker for the AFDC sample (OR = 0.92, 0.89-0.95) and became non-significant for children who exited welfare. Current welfare receipt remained a strong predictor of CMR likelihoods for both CAN (OR = 2.32, 1.98-2.71) and AFDC (OR = 2.08, 1.61-2.68) samples. Prior welfare receipt moderately increased CMR likelihoods among those not currently on welfare. Controlling for other risk factors, White children had the highest likelihood of CMR. Other child and parent level vulnerabilities also increased CMR risk over time. CONCLUSIONS This study highlights the importance of longitudinal analytic approaches and the utility of cross-sector administrative data in improving our ability to understand and predict CMRs over time. Congenital radioulnar synostosis (RUS) is a rare skeletal disorder that is characterized by fusion of the radius and ulna. As the etiology of RUS is largely unknown, its treatment options are currently limited. learn more A de novo missense mutation in the zinc finger matrin-type 2 (ZMAT2) gene was newly identified in a 5-year-old boy with RUS using whole-exome sequencing. Herein, we sought to further explore the function of zmat2 in zebrafish. Whole-mount in situ hybridization revealed site-specific expression of zzmat2 in the pectoral fins (equivalent to human upper limbs) and craniofacial regions, while immunohistochemistry showed the expression of zZmat2 in the pectoral fins and heart region. Gene knockdown produced defects in the pectoral fins and dorso-ventral patterning. zzmat2 knockdown also caused embryo dorsalization, a phenotype consistent with reduced/insufficient bone morphogenetic protein (BMP) signaling. These abnormalities were partially rescued by zbmp2b RNA overexpression and fully rescued by simultaneous overexpression of wild-type zzmat2.
