Effect of postbiotic Lactiplantibacillus plantarum LRCC5314 supplemented in powdered milk on type 2 diabetes in mice

Type 2 diabetes (T2D) is a chronic multifactorial disease characterized by a combination of insulin resistance and impaired glucose regulation. The alleviative effects of probiotics on T2D have been widely studied. However, studies on the effects of postbiotics, known as inactivated probiotics, on dairy products are limited. This study aimed to evaluate the effectiveness of postbiotic Lactiplantibacillus plantarum LRCC5314 in milk powder (MP-LRCC5314) in a stress-T2D mouse model. Compared with probiotic MP-LRCC5314, postbiotic MP-LRCC5314 significantly influenced stress-T2D-related factors. The administration of heat-killed MP-LRCC5314 reduced corticosterone levels, increased short-chain fatty acid production by modulating gut microbiota, and regulated immune response, glucose metabolism, stress-T2D-related biomarkers in the brain, gut, and adipose tissues, as well as glucose and insulin sensitivity. Additionally, heat-killed MP-LRCC5314 treatment led to a decrease in pro-inflammatory cytokine levels and an increase in anti-inflammatory cytokine levels. Overall, these findings suggest that adding postbiotic MP-LRCC5314 to milk powder could serve as a potential supplement for stress-T2D mitigation.

Ameliorating effect of 2'-Fucosyllactose and 6'-Sialyllactose on lipopolysaccharide-induced intestinal inflammation

Human milk oligosaccharides (HMO) affect gut microbiota during neonatal development, particularly with respect to the immune system. Bovine milk-based infant formulas have low oligosaccharide contents. Thus, efforts to fortify infant formulas with HMO are being undertaken. Two major HMO, 2'-fucosyllactose (2'-FL) and 6'-sialyllactose (6'-SL), exert anti-inflammatory effects; however, the associations between anti-inflammatory effects induced by 2'-FL and 6'-SL co-treatment and gut microbiota composition and metabolite modulation remain unclear. Therefore, in this study, we evaluated the effects of a mixture of these HMO. To determine the optimal HMO ratio for anti-inflammatory effects and elucidate its mode of action, LPS-induced inflammatory HT-29 epithelial cells and intestinal inflamed suckling mice were treated with various mixtures of 2'-FL and 6'-SL. 2'-FL:6'-SL ratio of 5:1 was identified as the most effective pre-treatment HMO mixture in vitro; thus, this ratio was selected and used for low, middle, and high-dose treatments for subsequent in vivo studies. In vivo, high-dose HMO treatment restored LPS-induced inflammation symptoms, such as body weight loss, colon length reduction, histological structural damage, and intestinal gene expression related to inflammatory responses. High-dose HMO was the only treatment that modulated the major phyla Bacteroidetes and Firmicutes and the genera Ihubacter, Mageeibacillus, and Saccharofermentans. These changes in microbial composition were correlated with intestinal inflammation-related gene expression and short-chain fatty acid production. To our knowledge, our study is the first to report the effects of Ihubacter, Mageeibacillus, and Saccharofermentans on short chain fatty acid levels, which can subsequently affect inflammatory cytokine and tight junction protein levels. Conclusively, the HMO mixture exerted anti-inflammatory effects through changes in microbiota and metabolite production. These findings suggested that supplementation of infant formula with HMO may benefit formula-fed infants by forming unique microbiota contributing to neonatal development.

Parenting attitudes and behaviors among parents involved with the child welfare system and affected by substance use disorders

BACKGROUND

Co-occurring parental substance use and child maltreatment is a serious concern in the U.S child welfare system.

OBJECTIVE

The aim of the study was to examine parenting attitudes and practices among parents who participated in Ohio START (Sobriety, Treatment, And Reducing Trauma), a statewide initiative that provides support to families affected by co-occurring parental substance use and child maltreatment.

PARTICIPANTS AND SETTING

Study 1 involved quantitative data collected from 73 enrolled parents through pre-test and post-test telephone surveys. Study 2 (parent interviews) involved qualitative data collected through in-depth interviews with 34 enrolled parents.

METHODS

The paired-sample t-test and the McNemar test were conducted in Study 1 and thematic analysis was conducted in Study 2.

RESULTS

Quantitative analysis indicated significant improvements in parental expectations of children (t = -3.42, p = .001, Cohen's d = -0.40), parent-child family roles (t = -5.74, p < .001, Cohen's d = -0.67), and children's power and independence (t = -3.42, p = .001, Cohen's d = -0.40). Qualitative analysis revealed six themes related to changes in parenting after participation in Ohio START: (1) Being present for children, (2) Engaging in activities with children, (3) Enjoyment in providing care to children, (4) Maintaining employment for financial stability, (5) Better emotion regulation and stress management, and (6) a sense of pride.

CONCLUSIONS

Our findings demonstrate positive changes in parenting attitudes and practices among parents who participated in Ohio START and provide further support for the potential merits of this model and its continued expansion throughout Ohio.

Examination of protective factors that promote prosocial skill development among children exposed to intimate partner violence

This retrospective cohort study examined prosocial skills development in child welfare-involved children, how intimate partner violence (IPV) exposure explained heterogeneity in children's trajectories of prosocial skill development, and the degree to which protective factors across children's ecologies promoted prosocial skill development. Data were from 1,678 children from the National Survey of Child and Adolescent Well-being I, collected between 1999 and 2007. Cohort-sequential growth mixture models were estimated to identify patterns of prosocial skill development between the ages of 3 to 10 years. Four diverse pathways were identified, including two groups that started high (high subtle-decreasing; high decreasing-to-increasing) and two groups that started low (low stable; low increasing-to-decreasing). Children with prior history of child welfare involvement, preschool-age IPV exposure, school-age IPV exposure, or family income below the federal poverty level had higher odds of being in the high decreasing-to-increasing group compared with the high subtle-decreasing group. Children with a mother with greater than high school education or higher maternal responsiveness had higher odds of being in the low increasing-to-decreasing group compared with the low stable group. The importance of maternal responsiveness in fostering prosocial skill development underlines the need for further assessment and intervention. Recommendations for clinical assessment and parenting programs are provided.

Trajectories of resilience among young children involved with child protective services

Although child maltreatment is associated with short- and long-term maladaptive outcomes, some children are still able to display resilience. Currently, there is a limited understanding of how children's resilience changes over time after experiencing maltreatment, especially for young children. Therefore, the current study used a longitudinal, multidimensional approach to examine trajectories of resilience among very young children involved in child protective services and determine whether placement setting and caregiving behaviors are associated with resilience trajectories. This study used data from National Survey of Child and Adolescent Well-Being I and conducted repeated measures latent class analysis, focusing on children under 2 years old at baseline (n = 1,699). Results suggested that there were three trajectories of resilience: increasing resilience, decreasing resilience, and stable, low resilience. Caregiver cognitive stimulation was related to increasing trajectories of resilience compared to both decreasing and stable, low resilience. These findings illustrate the importance of caregiving behaviors for promoting resilience among a particularly vulnerable population.

Can resilience change over time? Patterns and transitions in resilience among young children involved with the child welfare system

This study examined transitions in resilience profiles and the role of caregiver risk and protective factors in resilience transition probabilities over 18 months among children involved with the child welfare system, using latent profile analysis and latent transition analysis. The sample included 486 children (48% female, baseline Mage  = 3.49). There were three resilience profiles at Time 1 (19.9% low emotional behavioral, 26.1% low cognitive, 54.0% multidomain) and two profiles at Time 2 (18.9% low emotional behavioral, 81.1% multidomain). Caregiver mental health problems were negatively associated with membership in the multidomain resilience group at Time 1. Higher levels of cognitive stimulation were associated with initial and continued membership in the multidomain resilience group. Implications for resilient child development are discussed.

Association between longitudinal patterns of child maltreatment experiences and adolescent substance use

BACKGROUND

Although there is a well-established link between child maltreatment and adolescent substance use, it remains unclear if and how longitudinal patterns of maltreatment experiences are associated with substance use in adolescence.

OBJECTIVE

The purpose of the study was to examine how distinct patterns of longitudinal maltreatment experiences are associated with adolescent substance use.

PARTICIPANTS AND SETTING

The participants were 899 adolescents from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN).

METHODS

We conducted repeated measures latent class analysis (RMLCA) to identify patterns of physical abuse, sexual abuse, and neglect from birth to age 17 and their relations to tobacco, alcohol, and marijuana use at age 18.

RESULTS

RMLCA identified three physical abuse classes (Stable low physical abuse; School age peak physical abuse; Physical abuse primarily in infancy/toddlerhood), two sexual abuse classes (Stable no/low sexual abuse; School age peak sexual abuse), and three neglect classes (High neglect in childhood; Neglect primarily in infancy/toddlerhood; Neglect primarily at school age). Adolescents in the school age peak physical abuse class showed greater alcohol, cigarette, and marijuana use, compared to other physical abuse classes. Similarly, adolescents in the school age peak sexual abuse class showed greater substance use than those in the stable no/low sexual abuse class. Lastly, adolescents in the neglect primarily in infancy/toddlerhood class showed significantly less substance use than those in the other two neglect classes.

CONCLUSIONS

Findings highlight the importance of early intervention and ongoing maltreatment prevention.

Coparenting, parental anxiety/depression, and child behavior problems: The actor-partner interdependence model with low-income married couples

A considerable amount of research has suggested significant associations among perceived coparenting relationships, parental anxiety/depression, and children's adjustment. Although family members' function is influenced by other members in a shared context, much of the prior work relied on one parent's perspective to examine the relationship between both parents. To address this important limitation, we applied the actor-partner interdependence model and accounted for the interdependence between fathers and mothers in examining the mediating role of parental anxiety/depression in the association between coparenting quality and child behavior problems. The present study included 1,827 low-income couples from the Supporting Healthy Marriage project (mothers: 51.25% of White, 14.34% African American, 35.31% Hispanic; fathers: 48.11% White, 18.54% African/Black American, 35.34% Hispanic). The results showed that both fathers' and mothers' perceptions of coparenting quality had significant effects on fathers' anxiety/depression. In contrast, mothers' anxiety/depression was affected only by mothers' perceptions of coparenting quality and not by fathers' perceptions. Overall, the effects of parents' perception of coparenting on children's internalizing and externalizing behavior problems were largely mediated by parental anxiety/depression. The findings highlight both interdependent and independent roles of fathers and mothers in the pathways from coparenting quality to children's behavior problems.

A Qualitative Study of Risk and Protective Factors for Resilience in Survivors of Sex Trafficking

This study explored risk and protective factors for resilience in survivors of sex trafficking from the survivors' perspectives. In-depth interviews were conducted with 16 participants recruited from survivor-led advocacy agencies and social service agencies that provide trafficking-specific services. Two overarching themes emerged from data analysis: (a) deep connections to self and others facilitate resilience and (b) detrimental "help" threatens survivors' resilience. Our findings suggest that it may be important for service providers to assist survivors build healthy relationships with themselves and others to promote survivors' resilience. Further, our results highlight the importance of offering more inclusive, survivor-centered, and trauma-informed services.

Environment matters: How are neighborhood structural indexes associated with parenting stress among Asian immigrant families?

The Asian immigrant population is the fourth largest immigrant population in the United States, and its parenting stress issues have been consistently recognized in previous studies. However, little attention has been paid to neighborhood-level factors and their parenting stress. Using the Study of Asian American Families and 2016 American Community Survey 5-year estimates, this study examined the association between neighborhood structural indexes and Asian immigrant parents' parenting stress, along with the mechanism driving the relationship. We found that cultural orientation and social support fully mediated the effects of economic disadvantages on parenting stress among Asian immigrant parents. Only cultural orientation mediated the direct effects of ethnic heterogeneity on Asian parents' parenting stress. Improving Asian immigrants' living environment, including economic status and ethnic diversity, would be critical to relieve the parenting stress of Asian immigrant families. Interventions and preventions to increase social support, and inform cultural orientation and acculturation are emphasized.

Are All Prognostic Stage IB Breast Cancers Equivalent?

PURPOSE/OBJECTIVE(S)

The 8th edition of the American Joint Committee on Cancer (AJCC) has recognized the prognostic influence of histologic grade and biomarker status for breast cancer (BC). Contemporary BC staging includes both anatomic tumor extent and prognostic stage. However, prognostic stage IB remains heterogeneous and includes patients with locally advanced anatomic pathologic stage IIIA-B (pT3N1 or pT1-3N2, G1-2) hormone-receptor positive/HER2-negative BC (LA-HR+/HER2-) as well as patients with early-stage anatomic clinical/pathologic stage IA (T1cN0, G2-3) triple-negative BC (ES-TNBC). We hypothesized that although both are classified as prognostic stage IB BC, overall survival (OS) is worse for LA-HR+/HER2- compared to ES-TNBC.

MATERIALS/METHODS

We used the National Cancer Database to identify patients with surgically-resected LA-HR+/HER2- BC (pT3N1 or pT1-3N2, grade 1-2) and those with ES-TNBC (T1N0, grade 2-3) from 2004-2017. Patients were excluded if receptor status, tumor grade, and/or TNM staging data were unknown. HR+/HER2- patients treated with neoadjuvant therapy were also excluded. The primary endpoint was OS. Multivariable Cox regression analysis was used to evaluate differences in OS between LA-HR+/HER2- BC and ES-TNBC (adjusting for baseline patient demographic characteristics) in the entire cohort and in the subset of patients that received appropriate treatment based on anatomic stage: radiation (RT), chemotherapy (CT) and hormone therapy for LA-HR+/HER2- BC and CT or CT+RT for ES-TNBC treated with mastectomy or lumpectomy, respectively. We report hazard ratios (HR) with 95% confidence intervals (CI) with p<0.05 considered statistically significant.

RESULTS

A total of 45,818 patients met inclusion criteria (N = 17,359 with LA-HR+/HER2- BC and N = 28,459 with ES-TNBC). Over 75% of the LA-HR+/HER2- BC patients have anatomic pathologic stage IIIB disease (pT1-3N2, G1-2). With a median follow-up of 56 months, the 6-year OS rates were 86.1% (LA-HR+/HER2-) vs. 90.4%patients (ES-TNBC) which corresponded to a 63% relative increased risk of death in LA-HR+/HER2- patients compared to ES-TNBC patients (HR = 1.63, 95% CI 1.53-1.73, p<0.0001) after adjusting for all covariates. Approximately 66% (N = 11,533) LA-HR+/HER2- and 69% (N = 19,512) ES-TNBC received appropriate therapy. The 6-year OS was 91.8% (LA-HR+/HER2-) vs. 93.3% (ES-TNBC) which corresponded to a 35% increased risk of death in the LA-HR+/HER2- patients compared to ES-TNBC (adjusted HR = 1.35, 95% 1.24-1.48, p<0.0001). Other covariates associated with OS were age, income, insurance status, facility type, and ethnicity/race.

CONCLUSION

We found that LA-HR+/HER2- BC has significantly worse OS compared to ES-TNBC despite both being classified as prognostic stage IB, even when accounting for treatments delivered. The categorization of pT3N1 or pT1-3N2, G1-2 HR+/HER2- BC as prognostic stage IB needs to be reconsidered in order to provide patients with more accurate information regarding expected OS.

Omission of Adjuvant Radiotherapy in Low-Risk Elderly Males with Breast Cancer

PURPOSE/OBJECTIVE(S)

Randomized clinical trials demonstrate that lumpectomy + hormone therapy (HT) without radiation therapy (RT) yields equivalent survival and acceptable local-regional outcomes in elderly women with early-stage, node-negative (T1-2N0) hormone-receptor positive (HR+) breast cancer. Whether these data apply to men with the same inclusion criteria remains unknown. We hypothesized that outcomes in males would be comparable to those seen in females, with RT not conferring an overall survival (OS) benefit over HT alone.

MATERIALS/METHODS

We conducted a retrospective matched-cohort study using the National Cancer Database for males ≥65 years with pathologic T1-2N0 (≤3 cm) HR+ breast cancer treated with breast conserving surgery with negative margins from 2004-2019. Patients who received chemotherapy, had nodal or distant metastases, or unknown follow-up were excluded. Adjuvant treatment was classified as HT alone, RT alone, or HT+RT. Due to limitations of survival analysis on retrospective data, male patients were matched with female patients to determine comparable outcomes based on age (± 3 years), Charlson Deyo comorbidity score, T-stage, and adjuvant treatment. Survival analysis was performed using Cox regression and Kaplan-Meier analysis. To adjust for confounding, inverse probability of treatment weighting (IPTW) was used.

RESULTS

A total of 523 patients met inclusion criteria, with 24.4% receiving HT, 16.3% receiving RT, and 59.2% receiving HT+RT. Median follow-up was 6.9 years (IQR: 5.0-9.4 years). Unadjusted 5-yr OS rates in the HT, RT, and HT+RT cohorts were 79.2% (95% CI 70.7-85.5%), 80.9% (95% CI 70.3-88.0%), and 93.3% (95% CI 89.7-95.7%), respectively. Adjusted 10-yr OS rates in the HT, RT, and HT+RT cohorts were 82.3% (95% CI 78.6-85.5%), 83.6% (95% CI 80.0-86.7%), and 92.8% (95% CI 90.1-94.8%), respectively. On unadjusted multivariable Cox regression analysis (MVA), relative to HT, receipt of HT+RT was associated with improvements in OS (HR: 0.603; 95% CI: 0.410-0.888; p = 0.01). RT alone was not associated with improved OS (HR: 1.116; 95% CI: 0.710-1.755; p = 0.633). On adjusted MVA, relative to HT, receipt of HT+RT was associated with improvements in OS (HR: 0.551; 95% CI: 0.370-0.820; p = 0.003). Again, RT alone was not associated with improved OS (HR: 0.991; 95% CI: 0.613-1.604; p = 0.972). Other factors associated with OS included age, Charlson Deyo score, T stage, and grade. Overall, in the matched women, the same trends were found as in the men, the best survival was in HT+RT, but no difference in OS between HT vs. RT.

CONCLUSION

Among men ≥65 years old with T1-2N0 HR+ breast cancer, RT alone did not confer an OS benefit over HT alone. Combined RT+HT did yield improvements in OS, though there are likely significant unmeasured confounders contributing to these outcomes in patients treated with the most aggressive approach. Our findings support that RT omission may be a reasonable option in elderly men with T1-2N0 HR+ breast cancer treated with lumpectomy + HT.

Longitudinal examination of resilience among child welfare-involved adolescents: The roles of caregiver-child relationships and deviant peer affiliation

Despite growing attention to resilience following childhood maltreatment, it remains unclear how the development of resilience unfolds over time among child welfare-involved adolescents. Further, little is known about the immediate and enduring effects of two important attachments in children's lives, namely caregiver-child relationship and deviant peer affiliation, on resilience development over time. This study sought to examine the ways in which caregiver-child relationships and deviant peer affiliation shape developmental trajectories of resilience among child welfare-involved youth. Data were drawn from the National Survey of Child and Adolescent Well-Being. Latent growth curve modeling was conducted on a sample of 711 adolescents. The results revealed that adolescents' resilience increased across a 36-month period since initial contact with Child Protective Services. Better caregiver-child relationships were associated with a higher initial level of resilience among adolescents, whereas higher deviant peer affiliation was associated with a lower initial level of resilience. Significant lagged effects were also found; caregiver-child relationship quality and deviant peer affiliation at baseline were associated with resilience at 18 months after. The findings suggest that interventions that aim to promote positive caregiver-child relationships and prevent deviant peer relationships may help foster resilience among adolescents who have experienced child maltreatment.

Sex Differences in Suicidal Ideation: Mediating Effects of Alcohol Abuse/Dependence on Suicidal Ideation through Psychological Distress and Hopelessness

This article aims to investigate the impact of psychological distress and hopelessness as mediators in the relationship between alcohol use disorder (AUD) and suicidal ideation among young adults. The study employed data from the 2019 National Survey on Drug Use and Health, focusing on participants aged 18 to 25. The PROCESS macro was used to conduct a moderated mediation analysis. The findings revealed that AUD, psychological distress, and hopelessness were all significant risk factors for suicidal ideation among young adults. Furthermore, psychological distress and hopelessness served as significant mediators in the relationship between AUD and suicidal ideation. The study highlights the need for interventions and treatments that address co-occurring alcohol use and psychological distress/hopelessness in both sexes, for young adults at risk of suicide. In summary, the study underscores the importance of recognizing the underlying factors that contribute to suicidal ideation among young adults, especially those with AUD, psychological distress, and hopelessness.

Safety and efficacy of trastuzumab biosimilar plus irinotecan or gemcitabine in patients with previously treated HER2 (ERBB2)-positive non-breast/non-gastric solid tumors: a phase II basket trial with circulating tumor DNA analysis

BACKGROUND

Human epidermal growth factor receptor 2 (HER2) (ERBB2)-directed agents are standard treatments for patients with HER2-positive breast and gastric cancer. Herein, we report the results of an open-label, single-center, phase II basket trial to investigate the efficacy and safety of trastuzumab biosimilar (Samfenet®) plus treatment of physician's choice for patients with previously treated HER2-positive advanced solid tumors, along with biomarker analysis employing circulating tumor DNA (ctDNA) sequencing.

METHODS

Patients with HER2-positive unresectable or metastatic non-breast, non-gastric solid tumors who failed at least one prior treatment were included in this study conducted at Asan Medical Center, Seoul, Korea. Patients received trastuzumab combined with irinotecan or gemcitabine at the treating physicians' discretion. The primary endpoint was the objective response rate as per RECIST version 1.1. Plasma samples were collected at baseline and at the time of disease progression for ctDNA analysis.

RESULTS

Twenty-three patients were screened from 31 December 2019 to 17 September 2021, and 20 were enrolled in this study. Their median age was 64 years (30-84 years), and 13 patients (65.0%) were male. The most common primary tumor was hepatobiliary cancer (seven patients, 35.0%), followed by colorectal cancer (six patients, 30.0%). Among 18 patients with an available response evaluation, the objective response rate was 11.1% (95% confidence interval 3.1% to 32.8%). ERBB2 amplification was detected from ctDNA analysis of baseline plasma samples in 85% of patients (n = 17), and the ERBB2 copy number from ctDNA analysis showed a significant correlation with the results from tissue sequencing. Among 16 patients with post-progression ctDNA analysis, 7 (43.8%) developed new alterations. None of the patients discontinued the study due to adverse events.

CONCLUSIONS

Trastuzumab plus irinotecan or gemcitabine was safe and feasible for patients with previously treated HER2-positive advanced solid tumors with modest efficacy outcomes, and ctDNA analysis was useful for detecting HER2 amplification.

Early childhood maltreatment and profiles of resilience among child welfare-involved children

Given the high burden of child maltreatment, there is an urgent need to know more about resilient functioning among those who have experienced maltreatment. The aims of the study were to: 1) identify distinct profiles of resilience across cognitive, emotional, behavioral, and social domains in young children involved in the child welfare system; and 2) examine maltreatment characteristics and family protective factors in relation to the identified resilience profiles. A secondary analysis was conducted using data from the National Survey of Child and Adolescent Well-Being (NSCAW-II). Latent profile analysis was performed on a sample of 827 children aged 3-5 years (46% girls, Mean age = 3.96). Three distinct resilience profiles were identified: 1) low cognitive resilience (24%); 2) low emotional and behavioral resilience (20%); and 3) multidomain resilience (56%). Caregiver cognitive stimulation, no out-of-home placement, higher caregiver education level, older child age, and being a girl were associated with the multidomain resilience profile. The findings provide empirical support for the multifaceted nature of resilience and suggest that practitioners need to help children achieve optimal and balanced development by assessing, identifying, and targeting those domains in which children struggle to obtain competence.

Father-Mother Co-Involvement in Child Maltreatment: Associations of Prior Perpetration, Parental Substance Use, Parental Medical Conditions, Inadequate Housing, and Intimate Partner Violence with Different Maltreatment Types

The current study applied a family systems approach to examine dyadic parental risk factors linked with mother-father co-involved physical abuse, neglect, sexual abuse, and emotional abuse. Parental substance use, mental health problems, disability and medical conditions, inadequate housing, economic insecurity, intimate partner violence, and prior maltreatment history were investigated as key risk factors at the dyadic parental level. Logistic regression analysis was conducted using national child welfare administrative data from the National Child Abuse and Neglect Data System. The results showed differential associations between risk factors and four child maltreatment types: physical abuse, neglect, emotional abuse, and sexual abuse. Intimate partner violence was associated with higher odds of mother-father co-involved neglect and emotional abuse. Parental substance use, inadequate housing, and prior maltreatment history were all associated with higher odds of mother-father co-involved neglect, but lower odds of physical abuse. Parental disability and medical conditions were associated with higher odds of mother-father co-involved sexual abuse, whereas parental substance use was associated with lower odds of sexual abuse. Implications include more nuanced ways of addressing multiple risk factors within the family to prevent future occurrences of child maltreatment involving both mothers and fathers.

Contextual factors of child behavioral health across developmental stages

This study examines the relative influence of environmental contexts (family, school, neighborhood) on child behavioral health at ages 3, 5, 9, and 15 years. Path analysis was conducted on a sample of 4,898 urban children from a longitudinal dataset called the Fragile Families and Child Wellbeing Study. Child physical abuse, emotional abuse, maternal depression, substance use, neighborhood social cohesion, neighborhood poverty, school connectedness, and peer bullying had concurrent relationships with child behavior problems at one or more developmental stages. Early childhood abuse (age 3) and school age environmental contexts (age 9) had lasting effects on later behavior problems. Findings underscore the importance of both multilevel contextual factors and developmental timing in determining behavioral health outcomes in children.

Implementation and Mental Health Outcomes of a Service Cascade Linking Child Welfare and Children's Mental Health Systems: A Case Study of the Gateway CALL Demonstration

The mental health needs of children and youth involved in the child welfare system remain largely unmet. Service cascades are an emerging approach to systematizing mental health screening, assessment, and treatment referral processes. However, evidence is minimal and inconsistent regarding the effectiveness of such approaches for improving mental health service access and outcomes. In an effort to address this gap, this study presents a case-study of the implementation fidelity and treatment outcomes of the Gateway CALL service cascade. Study analyses involved longitudinal data collected as part of a larger evaluation of Gateway CALL. Specifically, descriptive and linear mixed model analyses were conducted to assess the implementation of service cascade components, and changes in mental health outcomes (behavior problems) among 175 children placed out-of-home during the study. Study analyses found that although fidelity was strong early in the service cascade, implementation began to break down once components involved more than one service system (child welfare, mental health). However, results also indicated that parent-reported child behavior problems decreased significantly over time, despite later cascade components being implemented with poor fidelity to the Gateway CALL service model. For children and youth involved in child welfare systems, service cascades like Gateway CALL have the potential to significantly improve both mental health service receipt and outcomes. To maximize the effectiveness of such approaches, later phases of implementation may require increased attention and support, particularly regarding processes and outcomes that cross child welfare and mental health service systems.

Sync and Swarm: Solvable Model of Nonidentical Swarmalators

We study a model of nonidentical swarmalators, generalizations of phase oscillators that both sync in time and swarm in space. The model produces four collective states: asynchrony, sync clusters, vortexlike phase waves, and a mixed state. These states occur in many real-world swarmalator systems such as biological microswimmers, chemical nanomotors, and groups of drones. A generalized Ott-Antonsen ansatz provides the first analytic description of these states and conditions for their existence. We show how this approach may be used in studies of active matter and related disciplines.

Benchmarking Trauma in Child Welfare: A Brief Report

Trauma exposure is common; however, considerably higher rates are reported in some vulnerable groups including adults and children involved in child welfare systems. In this context, early screening and service linkage may ameliorate its negative impact on the physical and mental well-being of adults and children alike. Using data from two Ohio-based child welfare interventions targeting co-occurring maltreatment and substance use (Ohio START¹ and EPIC2), the purpose of this brief report was to first describe the rate of trauma exposure among participating adults (Adverse Childhood Experiences or ACEs, N = 402), children 0-5 years (CTAC, N = 271) and youth 6-18 years (CTAC, N = 177), and second to benchmark observed rates against reported rates in other child welfare or similar populations across the United States. Results show that adults were exposed to 4.2 ACEs on average, a 24% increase over previous child welfare estimates. While mean CTAC scores were not significantly different among young children ages 0-5, older children reported on average 5.6 exposures which is 27% higher than previously reported estimates. Our findings highlight the difference in risk profiles between families involved child welfare due primarily to substance misuse and those without substance misuse concerns, or where substance misuse was not the primary cause of entry. We discuss implications for service provision and time-sensitive child welfare requirements.

OS10.6.A What is the initial cell in the subventricular zone for human glioblastoma genesis?

Background

We all have a fundamental question about why glioblastoma (GBM) develops. In order to find the answer to this fundamental question, if you find out what the first cell is, you will get closer to the answer. GBM arises from the subventricular zone (SVZ). GBM is one of the most devastating tumour of human brain as the most optimal treatment barely prolongs the survival, and it does not cure the disease. As the majority of GBM tissues show copy number variations (CNV) of co-altered chromosomal 7 gain and 10 loss, we hypothesized the origin cell (Oc) of SVZ may be traced back with these markers. The cellular identity of the Oc is still unknown and it is different from the tumour-derived progenitor-like cells. We aimed to define these cells from the SVZ that have a potential to get activated into GBM.

Material and Methods

We compared bulk RNA sequencing (RNAseq) data of IDHwt GBM tumor tissue (n=122), tumor free SVZ from GBM patients (n=40), tumor-free control SVZ of non-glial tumor (n=9). Pared single nucleus RNAseq (snRNAseq) or single cell RNAseq (scRNAseq) samples of tumor free SVZ (n=11) and GBM tumor (n=8), were done to see cell specific CNVs. We developed genetically engineered mouse models for GBM genesis introducing three driver mutations (TP53, PTEN, and EGFRviii) into SVZ to isolate mouse Oc (mOc) and mouse cancer cells (mCc). The biological characteristics of separated mOc and mCc were compared. Bulk RNAseq and scRNAseq were performed on these cells (mOc, mCc), and their cellular state was compared with the human gene set.

Results

In this work, we found two types of the Oc in the RNA sequencing of 60 human tumour free-SVZ samples. Furthermore, single-cell level analysis revealed that two Oc types in SVZ harbor ongoing patterns of CNV co-alterations from Oc1 to Oc2, and finally to GBM. The Oc1 type cells contained the CNV signature of Oc2 ancestor with neural progenitor cell (NPC) signature. Oc2 type cells expressed a high level of EGFR than other cells with astrocyte-like cell signature. Both of these cells expressed oligodendrocyte progenitor cell (OPC)-like signatures in the SVZ. We validated the human-based findings by using the P53/PTEN/EGFR-mutant mouse model with EGFR/tdTomato overexpression and P53/PTEN knockout in the SVZ cells. As a result, non-tumourigenic and highly motile Oc-like cell-states are found in the mouse models, supporting the firework-like migration pattern from the SVZ.

Conclusion

Our results demonstrate how members of Oc preoccupy the SVZ, known as the stem cell niche and give rise to the tumour. We anticipate that a new therapy may emerge by targeting the Oc in the SVZ.

The Interaction Effects Between Father-Child Relationship Quality and Parent-perpetrated Maltreatment on Adolescent Behavior Problems

Despite ample evidence supporting the positive and important role fathers play in youth well-being, currently little is known about the potential buffering effects of positive father-child relationships on adolescent behavioral functioning, especially within the context of child maltreatment. Clarifying whether positive parent-child relationships are helpful in the presence of maltreatment perpetrated by the same or another parent is critical for designing and implementing successful family-based interventions for positive youth development. Thus, the present study aimed to investigate the unique and combined effects of the perpetrator of child maltreatment (i.e., maltreatment perpetrated by fathers versus mothers alone) and father-child relationship quality on adolescent internalizing and externalizing problems. A series of Ordinary Least Squares multiple regressions were conducted on a sample of 14-year-old high-risk youth (N = 661) drawn from the Longitudinal Studies of Child Abuse and Neglect. The results indicated that both father-perpetrated maltreatment and mother-alone maltreatment were associated with higher levels of internalizing and externalizing problems. Higher quality of father-child relationships was associated with lower levels of internalizing but was not significantly associated with externalizing problems. Higher quality father-child relationships had a buffering impact against adolescent internalizing and externalizing problems when adolescents were maltreated by mothers alone. The findings suggest that policy and practical efforts seeking to build resilience of youth should strive to nurture and leverage positive, non-maltreating father-child relationships. Such efforts may support the positive development of adolescents, even in the face of mother-perpetrated maltreatment.

Fully automatic AI-based valve motion parameter extraction on long axis CINE images - application on N=11000 patient datasets

Type of funding sources: Private company. Main funding source(s): Research support from Siemens Healthineers GmbH.

Background

Mitral valve (MV) motion parameters, assessable using CMR [1, 2], have been shown to help the diagnosis of cardiac dysfunction. To extract valve motion parameters, we propose a fully automatic AI-based prototype system that tracks annulus and apex landmarks by the registration network on time-resolved two- and four-chamber CMR cine views. Parameters such as displacements, velocities, mitral annular plane systolic excursion (MAPSE), or longitudinal shortening (LS) are automatically extracted and evaluated on a large CMR dataset (N=11000).

Methods

The system consists of two sequential neural networks with a processing step in between (Fig. 1a) [3]. Initially, a 2D UNet is applied to localize both MV annulus insertion points as well as the apex. Based on these points, the image processing step consists of rotating, cropping, and interpolating the images, allowing a standardized image impression for both long axis views. Finally, the registration network (VoxelMorph framework [4]) is applied to the processed series and tracks the MV annulus insertion points and apex over the cardiac cycle by the deformation fields obtained by the network. The system was trained on (N=166) multivendor, multi-field strength, ground-truth annotated datasets [5].

A total of 11000 datasets, acquired on a 1.5T scanner (MAGNETOM Aera, Siemens Healthcare, Erlangen, Germany) from January 2016 to September 2017 [6], were used for parameter extraction. 200 of these datasets were additionally annotated semi-automatically for the performance evaluation of the system.

Five motion parameters were automatically derived by the system that are defined as follows (Fig. 1b): (1) The atrioventricular plane displacement (AVPD) as the distance of the plane spanned by the MV annulus points relative to the first frame, (2) the atrioventricular plane velocity (AVPV) as the discrete temporal derivate of the AVPD, (3) the diameter of the annulus as the maximum distance between the MV annulus points, (4) the lateral/inferior and septal/superior MAPSE, as the maximum MV points’ excursion, and (5) the LS as the percentage size difference of the distance between the mid valvular point and the apex point at end-systole and end-diastole.

Results

The accuracy of the system resulted in deviations on the annotated dataset of 1.02 ± 0.87 mm, 0.01 ± 0.02 mm/s, 1.54 ± 1.21 mm, 2.30 ± 1.35 mm, 2.1 ± 1.8 mm for AVPD, AVPV, diameter, MAPSE, and LS respectively. Initial statistics on all datasets (Fig. 2) revealed a mean lateral/inferior, septal/superior MAPSE and LS of 8.7 ± 2.7 mm, 10.5 ± 3.2 mm and 16.3 ± 4.2 % for two-chamber and 9.6 ± 2.6 mm, 8.7 ± 2.6 mm and 15.5 ± 3.9 % for four-chamber views, respectively.

Conclusions

The results demonstrate the versatility of the proposed system for automatic extraction of various MV motion parameters. The proposed system enables automatic extraction of clinically relevant parameters and can improve the automation of MV-based analyses.

Fully automated machine learning-based selection of optimal bSSFP frequency offset for artifact reduction in cardiac MRI

Funding Acknowledgements

Type of funding sources: Private company. Main funding source(s): Research Support from Siemens Healthineers GmbH.

Background

In bSSFP sequences commonly used for cardiac MRI, signal modulation (e.g. banding artifacts) due to B0 inhomogeneity is often observed, especially at higher field strengths. The spatial position of these artifacts can be shifted by a frequency offset to reduce artifacts in a region of interest (ROI), e.g. the heart. To this end, frequency scout (FS) scans are acquired to visually select the optimal frequency offset [1,2]. In this work, we propose a fully automated image-based system for selecting the optimal frequency offset on FS images based on machine learning.

Methods

The proposed prototype system consists of four main steps (Fig.1). First, a pre-trained deep-learning-based whole heart segmentation network is applied on a four chamber-view FS image to localize the ROI where artifacts should be reduced. Second, high frequency components within the ROI (for each frequency offset in the FS series) are extracted by successive processing of Fourier transformation, high-pass filtering, inverse Fourier transformation and subtraction over series. and N images with the lowest high-frequency content are selected. Third, an adaptive weighting map for each FS image is generated which penalizes signal deviations from a pixel-wise median that is calculated based on the selected images [3]. By averaging the maps and selecting the frame with maximum percentage, the optimal frequency offset is selected.

A total of 38 datasets, acquired on multiple clinical 3T MRI scanners (MAGNETOM Skyra, Vida, Prisma, Lumina; Siemens Healthcare, Erlangen, Germany), were used to evaluate the proposed system. All FS series were annotated manually and used to compare with the system output. The experts were allowed to select multiple possible optimal FS images within a FS series. In case of multiple annotations, the system output was labelled as correct when it selected one of the offsets chosen by the expert. Further, the generated weighting maps were visually evaluated.

Results

The proposed system achieved an accuracy of 92.1% compared to experts’ ground truth annotations. From the failed cases (n=3), the maximum difference was off by 2 frames. Based on the generated weighting maps, a reasonable decision on the selection of the optimal frequency offset is made. The algorithm successfully selects an FS image with minimized banding and flow artifacts within the ROI (Fig. 2a). Further, it reveals that the generated weighting map correctly suppress areas containing artifacts (Fig. 2b).

Conclusions

Initial results demonstrate the feasibility of the proposed system to automatically select the optimal frequency offset on FS scans. Therefore, it can improve the automation of a cardiac MRI workflow. An example of the result of each step

Social Cohesion and Informal Social Control as Mediators Between Neighborhood Poverty and Child Maltreatment

Neighborhoods have profound impacts on children and families. Using structural equation modeling and data from 4,898 children in the Fragile Families and Child Wellbeing Study, the current study examines the direct and indirect effects of neighborhood poverty on the likelihood of being maltreated at age 5. Two neighborhood social processes, social cohesion and informal social control, were examined as mediators. The study found that neighborhood poverty was indirectly related to physical assault and psychological aggression through its impact on social cohesion, and indirectly related to neglect through its impact on informal social control. The results highlight the need to reduce poverty across communities and increase social cohesion and social control as potential pathways for interrupting the impact of neighborhood poverty on maltreatment.

A robust experimental and computational analysis framework at multiple resolutions, modalities and coverages

The ability to study cancer-immune cell communication across the whole tumor section without tissue dissociation is needed, especially for cancer immunotherapy development, which requires understanding of molecular mechanisms and discovery of more druggable targets. In this work, we assembled and evaluated an integrated experimental framework and analytical process to enable genome-wide scale discovery of ligand-receptors potentially used for cellular crosstalks, followed by targeted validation. We assessed the complementarity of four different technologies: single-cell RNA sequencing and Spatial transcriptomic (measuring over >20,000 genes), RNA In Situ Hybridization (RNAscope, measuring 4-12 genes) and Opal Polaris multiplex protein staining (4-9 proteins). To utilize the multimodal data, we implemented existing methods and also developed STRISH (Spatial TRanscriptomic In Situ Hybridization), a computational method that can automatically scan across the whole tissue section for local expression of gene (e.g. RNAscope data) and/or protein markers (e.g. Polaris data) to recapitulate an interaction landscape across the whole tissue. We evaluated the approach to discover and validate cell-cell interaction in situ through in-depth analysis of two types of cancer, basal cell carcinoma and squamous cell carcinoma, which account for over 70% of cancer cases. We showed that inference of cell-cell interactions using scRNA-seq data can misdetect or detect false positive interactions. Spatial transcriptomics still suffers from misdetecting lowly expressed ligand-receptor interactions, but reduces false discovery. RNAscope and Polaris are sensitive methods for defining the location of potential ligand receptor interactions, and the STRISH program can determine the probability that local gene co-expression reflects true cell-cell interaction. We expect that the approach described here will be widely applied to discover and validate ligand receptor interaction in different types of solid cancer tumors.

AB0344 EFFICACY OF SUBCUTANEOUS INFLIXIMAB (CT-P13 SC) COMPARED WITH INTRAVENOUS INFLIXIMAB IN RHEUMATOID ARTHRITIS: A POST-HOC ANALYSIS OF A PHASE 3 RANDOMIZED CONTROLLED TRIAL

Background

Subcutaneous (SC) CT-P13 is the first and only subcutaneous formulation of infliximab (IFX) approved by the EMA.1 In the pivotal study (NCT03147248), non-inferiority of SC IFX to intravenous (IV) was demonstrated in rheumatoid arthritis (RA) patients using 28-joint Disease Activity Score (DAS28) C-reactive protein (CRP) improvement at Week 22, with a statistically significant treatment difference of 0.27 (95% CI 0.02, 0.52) favoring the SC versus the IV arm.2,3 At Week 30, numerical differences in efficacy outcomes were shown between SC and IV IFX favoring SC IFX. IV group patients switched to SC IFX by Week 30, and the difference between the groups was reduced at Week 54.2

Objectives

To investigate whether there was a statistically significant difference between SC and IV IFX at Weeks 30 and 54 in the phase 3 pivotal study of CT-P13 SC using conservative missing imputation methods.

Methods

Patients with active RA who had an inadequate response to MTX received IV IFX 3mg/kg at Weeks 0 and 2 for induction and were randomized at a 1:1 ratio to receive SC IFX 120mg every 2 weeks or IV 3mg/kg every 8 weeks thereafter for maintenance. Patients who were randomized to receive IV IFX switched to SC at Week 30. In this post-hoc analysis, non-responder imputation (NRI) and last observation carried forward (LOCF) methods were used to investigate whether the difference in efficacy outcomes between SC and IV IFX at Weeks 30 and 54 was statistically significant. Assessments included EULAR (CRP/ESR)/ACR response; remission rate and low disease activity (LDA) rate based on DAS28 (CRP/ESR), Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI); Boolean remission rate; and the proportion of patients achieving a minimal clinically important difference (MCID) in Health Assessment Questionnaire (HAQ).

Results

Of the 343 randomized patients, 165 patients who received SC IFX and 174 patients who received IV IFX from the efficacy population were included in the analysis. There was a statistically significant difference in SC IFX compared to IV treated patients at Week 30 using both NRI and LOCF methods in almost all the clinical variables. However, the difference in efficacy outcomes between SC IFX and IV was reduced at Week 54 after the IV group switched to SC. This supports the improved efficacy of SC IFX at Week 30. Some of the key results (EULAR [CRP] responses, LDA rates based on DAS28 [CRP], CDAI, and SDAI) were presented in Figure 1. Analysis using LOCF and NRI methods yielded consistent results across most of the efficacy outcomes.

Conclusion

Statistical analyses using conservative missing imputation methods showed significantly greater improvements in clinical outcomes with SC IFX compared to IV at Week 30 in patients with RA. Between-group differences was reduced at Week 54, suggesting improved responses after switching from IV to SC.

The Long-Term Effects of Early Childhood Resilience Profiles on School Outcomes among Children in the Child Welfare System

This study aimed to examine the association between early childhood resilience profiles and later school outcomes (academic achievement and school involvement) among children in the U.S. child welfare system. This study compared 827 children aged 3–5 years in three latent profile groups (poor emotional and behavioral resilience, low cognitive resilience, and multi-domain resilience) to their baseline profiles using data from the National Survey of Child and Adolescent Well-Being (NSCAW-II). At the three-year follow-up, children with low emotional and behavioral resilience profiles and children with the multi-domain resilience profile had significantly higher basic reading skills, reading comprehension, and math reasoning compared to children with low scores on the cognitive resilience profile. Furthermore, children with the multi-domain resilience profile had significantly higher levels of emotional school engagement than did those with the low emotional and behavioral resilience profile and considerably higher levels of behavioral school engagement compared to those with the low cognitive resilience profile. The findings highlight the persistent effects of early resilience into the later childhood years. Moreover, our results suggest the need for early identification of and intervention for children with low cognitive or emotional/behavioral resilience during the preschool years to promote academic success and school engagement during the school-age years.

Racial differences in early adolescent substance use: Child abuse types and family/peer substance use as predictors

This study examined the associations among child abuse types, family/peer substance use, and adolescent substance use, as well as testing whether these associations vary by race. The sample was derived from the Longitudinal Studies of Child Abuse and Neglect (N = 562). Child sexual abuse, family substance use, and peer substance use were associated with a higher likelihood of adolescent substance use. Sexual abuse was more strongly associated with substance use in Black youth than in White youth. Conversely, greater peer substance use had a stronger association with substance use in White youth than in Black youth.

The Relative Influence of Family and Neighborhood Factors on Child Maltreatment at Critical Stages of Child Development

This study examines the impact of family and neighborhood factors on physical and psychological abuse across three developmental stages of children: early childhood (age 3), young school age (age 5), and middle childhood (age 9). Data from the Fragile Families and Child Wellbeing Study, a longitudinal national cohort study of children from 20 urban U.S. cities, are used. Path analysis is employed to investigate the longitudinal relationships between family and neighborhood context variables and abuse risk, as well as the importance of different factors at key developmental stages. Economic hardship, maternal substance use, intimate partner violence, and exposure to community violence are found to be related to child abuse risk regardless of developmental stage, while maternal depression and neighborhood informal social control are found to have impacts only within certain child development stages. Findings suggest the need for early intervention and prevention strategies that specifically target economic hardship, poverty, intimate partner violence, and exposure to community violence.

Neighborhood influences on early childhood behavioral problems: Child maltreatment as a mediator

BACKGROUND

A sizable number of previous research investigated the influences of untreated behavior problems in children's early age, as well as how different environmental factors affect child behavior problems (King et al., 2004; Vaillancourt et al., 2013). However, few studies focused on the influences of different types of neighborhood factors on early childhood internalizing and externalizing symptoms via adverse childhood experiences.

OBJECTIVE

This study aims to capture the specific pathways from neighborhood structural factors and process factors to early childhood internalizing and externalizing symptoms.

PARTICIPANTS AND SETTING

The restricted version of the Fragile Family Child Wellbeing Study (FFCWS) dataset at ages 3 and 5 were used, and 2722 children were included in the final model.

METHODS

The Structural Equation Model was used to estimate the pathways from neighborhood structural and process factors to early childhood internalizing (INT) and externalizing (EXT) symptoms. Neighborhood structural factors were measured at the census tract level. Neighborhood collective efficacy, child maltreatment experiences, and early childhood internalizing, and externalizing symptoms were reported by the focal child's mother.

RESULTS

Neighborhood process factors and structural factors showed both direct and indirect effects on early childhood EXT and INT differently. Emotional assault and neglect worked as mediators in this relationship.

CONCLUSIONS

Findings emphasize the importance for researchers and practitioners to involve neighborhood context when assisting children with early childhood behavior problems. Implications for research and interventions are further discussed.

Does mental health screening and assessment in child welfare improve mental health service receipt, child safety, and permanence for children in out-of-home care? An evaluation of the Gateway CALL demonstration

BACKGROUND

Unmet mental health service needs among children in out-of-home care are sometimes attributed to poor assessments and referrals in child welfare. The Gateway CALL project implemented mental health screening, diagnostic assessment, and referral to treatment practices.

OBJECTIVE

We examined the effectiveness of Gateway CALL for improving children's mental health service receipt, safety, and permanency outcomes.

PARTICIPANTS AND SETTING

Participants included 538 children (birth to 18 years) in out-of-home placements through a county-based child welfare agency over a 17-month period.

METHODS

We compared the mental health service receipt, safety, and permanency outcomes for 175 children who received Gateway CALL with 175 children who received "services as usual" identified through propensity score matching. Participant demographics, safety, and permanency outcomes were drawn from child welfare administrative records, and mental health service visits and diagnoses were drawn from Medicaid billing records.

RESULTS

Gateway CALL appeared to increase the number of mental health service visits children received (z = 2.14, p = 0.032), although not the likelihood of receiving services. In terms of child safety, children in Gateway CALL had a greater number of screened-in calls after the intervention than those in the comparison group [t(348) = -1.92, p = 0.03]; there were no differences in substantiations. There were also no observed effects on permanency.

CONCLUSIONS

Despite systematic efforts to identify, assess, and refer children to mental health services through the Gateway CALL intervention, substantial unmet mental health service needs among children persisted. Results have implications for designing interventions that promote cross-system service access.
