Serine racemase deletion alters adolescent social behavior and whole-brain cFos activation.

Background: Neurodevelopmental disorders (NDDs) can cause debilitating impairments in social cognition and aberrant functional connectivity in large-scale brain networks, leading to social isolation and diminished everyday functioning. To facilitate the treatment of social impairments, animal models of NDDs that link N- methyl-D-aspartate receptor (NMDAR) hypofunction to social deficits in adulthood have been used. However, understanding the etiology of social impairments in NDDs requires investigating social changes during sensitive windows during development. Methods: We examine social behavior during adolescence using a translational mouse model of NMDAR hypofunction (SR-/-) caused by knocking out serine racemase (SR), the enzyme needed to make D-serine, a key NMDAR coagonist. Species-typical social interactions are maintained through brain-wide neural activation patterns; therefore, we employed whole-brain cFos activity mapping to examine network-level connectivity changes caused by SR deletion. Results: In adolescent SR-/- mice, we observed disinhibited social behavior toward a novel conspecific and rapid social habituation toward familiar social partners. SR-/- mice also spent more time in the open arm of the elevated plus maze which classically points to an anxiolytic behavioral phenotype. These behavioral findings point to a generalized reduction in anxiety-like behavior in both social and non-social contexts in SR-/- mice; importantly, these findings were not associated with diminished working memory. Inter-regional patterns of cFos activation revealed greater connectivity and network density in SR-/- mice compared to controls. Discussion: These results suggest that NMDAR hypofunction - a potential biomarker for NDDs - can lead to generalized behavioral disinhibition in adolescence, potentially arising from disrupted communication between and within salience and default mode networks.

When I can be my whole authentic self, I feel safe and know that I belong: a photovoice study exploring what culturally safe pregnancy care is to Karen women of refugee background in Victoria, Australia.

OBJECTIVES: Inequitable pregnancy care experiences and outcomes disproportionately affect refugee background women in Australia. Culturally safe care is essential for achieving health equity, however, cultural safety can only be determined by the person receiving care. To our knowledge, women of refugee background in Australia are yet to be asked what culturally safe pregnancy care is to them. Specifically, this study aimed to explore what culturally safe pregnancy care is to Karen women (from Burma) of refugee background. DESIGN: A photovoice study founded on community-based participatory research principles was undertaken with a Karen community of refugee background living in Victoria, Australia. A community advisory group was established, guiding study design and conduct. Five S'gaw Karen-speaking women with experience of pregnancy care in Australia were invited to take photos within their community. Participants shared their photos and stories with each other in four online discussion groups. RESULTS: Reflexive thematic analysis guided by a critical constructionist lens developed three themes: Building foundations for belonging; cultivating reciprocal curiosity; and storytelling as an expression of self and shared power. These themes sit within the overarching theme When I can be my whole authentic self, I feel safe and know that I belong. CONCLUSION: When Karen women can embrace their cultural and spiritual identity without fear of discrimination, including racism, culturally safe pregnancy care is possible. This study contributes to the design and delivery of maternity services by providing insights that can enhance equitable and culturally safe pregnancy care for Karen women of refugee background.

Resilience and Positive Wellbeing Experienced by 5-12-Year-Old Children with Refugee Backgrounds in Australia: The Childhood Resilience Study.

Refugee research tends to be deficit based and focused on the risks threatening positive adaptation and wellbeing. High rates of mental (and physical) health issues have been reported for refugee adults and children, including intergenerational trauma. This study uses the new Child Resilience Questionnaire (CRQ), co-designed with refugee background communities, to describe resilience and positive wellbeing experienced by children of refugee-background. The Childhood Resilience Study (CRS) recruited 1132 families with children aged 5-12 years in Victoria and South Australia, Australia. This included the recruitment of 109 families from 4 refugee background communities: Assyrian Chaldean (Iraq, Syria), Hazara (Afghanistan), Karen (Burma, Thailand) and Sierra Leonean families. CRQ-parent/caregiver report (CRQ-P/C) scores were categorised into 'low', 'moderate' and 'high'. The child's emotional and behavioural wellbeing was assessed with the Strengths and Difficulties Questionnaire, with positive wellbeing defined as <17 on the total difficulties score. Tobit regression models adjusted for a child's age. The CRQ-P/C scores were not different for boys and girls of refugee background. Children of refugee-background (n = 109) had higher average CRQ-P/C scores than other CRS children (n = 1023) in the personal, school and community domains, but were lower in the family domain. Most children with 'high' resilience scores had positive wellbeing for both children of refugee-background (94.6%) and other CRS children (96.5%). Contrary to common stereotypes, children of refugee-background show specific individual, family, school and cultural strengths that can help them navigate cumulative and complex risks to sustain or develop their positive wellbeing. A better understanding as to how to build strengths at personal, family, peer, school and community levels where children are vulnerable is an important next step. Working in close collaboration with refugee communities, schools, policy makers and key service providers will ensure the optimal translation of these findings into sustainable practice and impactful public policy.

Patterns of intimate partner violence exposure across the first 10 years of life and children's emotional-behavioural outcomes at 10 years.

BACKGROUND: Childhood exposure to intimate partner violence (IPV) is associated with emotional-behavioural problems. However, little is known about children's emotional-behavioural outcomes following exposure to different long-term patterns of IPV. OBJECTIVE: The current study aimed to investigate the emotional-behavioural functioning of children at 10 years of age following exposure to different patterns of IPV across the first 10 years of life. PARTICIPANTS AND SETTING: Data for this study was drawn from the Mothers' and Young People's Study- a longitudinal study of 1507 first time mothers and their first born child. METHODS: Women were recruited during pregnancy from six public hospitals in Victoria, Australia. Data was collected during pregnancy, and at one, four and ten years postpartum. Four patterns of IPV exposure were previously identified: (a) minimal IPV exposure; (b) early IPV; (c) Increasing IPV; and (d) persistent IPV. Logistic regression was used to assess associations between IPV exposure and emotional-behavioural outcomes. RESULTS: Exposure to early, increasing, or persistent IPV was associated with increased odds of experiencing emotional-behavioural difficulties (OR 2.15-2.97). Children exposed to a persistent pattern of IPV experienced over 6 times the odds of conduct problems (OR = 6.15 CI = 2.3-16.44). CONCLUSIONS: Children exposed to early, increasing, or persistent IPV experienced increased odds of emotional-behavioural problems at age 10, regardless of the duration or type of violence they were exposed to. However, children exposed to persistent IPV across childhood appeared to experience the highest odds of emotional-behavioural difficulties.

WormBase 2024: status and transitioning to Alliance infrastructure.

WormBase has been the major repository and knowledgebase of information about the genome and genetics of Caenorhabditis elegans and other nematodes of experimental interest for over 2 decades. We have 3 goals: to keep current with the fast-paced C. elegans research, to provide better integration with other resources, and to be sustainable. Here, we discuss the current state of WormBase as well as progress and plans for moving core WormBase infrastructure to the Alliance of Genome Resources (the Alliance). As an Alliance member, WormBase will continue to interact with the C. elegans community, develop new features as needed, and curate key information from the literature and large-scale projects.

Perceptions and Experiences of Inequity for Women of Refugee Background Having a Baby during the COVID-19 Pandemic in Melbourne, Australia.

Listening to What Matters is an exploratory descriptive qualitative study that aimed to (1) understand how women of refugee background in Melbourne, Australia experienced access to health information and maternity and/or early parenting care during the COVID-19 pandemic and (2) whether pandemic health directives had an impact on structural inequities for women of refugee background who received maternity and/or early parenting care during the COVID-19 pandemic. Semi-structured interviews were conducted with 41 participants including 17 women of refugee background, who identified as belonging to the Karen, Assyrian Chaldean, Iraqi, Syrian, Afghan, Sudanese, or South Sudanese communities and 24 health and social care professionals who identified as providing pregnancy or early parenting care during the pandemic in the north western suburbs of Melbourne. Interviews with women were conducted in preferred languages by community researchers. Interviews with professionals were conducted in English by researchers. Reflexive thematic data analysis included constructivist positionality and a trauma and violence informed approach. The results reported in this paper include three themes, with four accompanying subthemes, as follows: theme (1), 'Structural inequities and the toll of the pandemic'; theme (2), 'Supportive infrastructure'; and theme (3), 'Cultural safety during the pandemic'. The results demonstrate that cumulative negative impacts such as unequal access to health information, family separation and isolation, inadequate household income, and mental and social health concerns had the potential to amplify pre-existing structural inequities for women of refugee background. Community engagement facilitated by bicultural workers, interpreters, and trusted care providers facilitated fast-paced, two-way communication that built capacity and health literacy for women who were unable to speak English and unfamiliar with the health care system and, improved experiences of care. More research is needed to understand how the intersectional cumulative impacts of structural inequities have affected maternal and neonatal health outcomes for women of refugee background during the pandemic, as well as any differences in maternal and neonatal health outcomes between Australian-born and refugee background women and babies.

Experiences of physical and emotional intimate partner violence during the COVID-19 pandemic: a comparison of prepandemic and pandemic data in a longitudinal study of Australian mothers.

OBJECTIVE: There is a lack of longitudinal population-based research comparing women's experiences of intimate partner violence (IPV) prior to and during the COVID-19 pandemic. Using data from the Mothers' and Young People's Study, the prevalence of physical and emotional IPV in the first year of the pandemic is compared with earlier waves of data. DESIGN: A prospective pregnancy cohort of first-time mothers in Melbourne, Australia was followed up over the first decade of motherhood, with a quick response study conducted during the COVID-19 pandemic. 422 women completed the primary exposure measure (IPV; Composite Abuse Scale) in the 1st, 4th and 10th year postpartum and the additional pandemic survey (June 2020-April 2021). OUTCOME MEASURES: Depressive symptoms; anxiety symptoms; IPV disclosure to a doctor, friends or family, or someone else. RESULTS: Maternal report of emotional IPV alone was higher during the pandemic (14.4%, 95% CI 11.4% to 18.2%) than in the 10th (9.5%, 95% CI 7.0% to 12.7%), 4th (9.2%, 95% CI 6.8% to 12.4%) and 1st year after the birth of their first child (5.9%, 95% CI 4.0% to 8.6%). Conversely, physical IPV was lowest during the pandemic (3.1%, 95% CI 1.8% to 5.0%). Of women experiencing IPV during the pandemic: 29.7% were reporting IPV for the first time, 52.7% reported concurrent depressive symptoms and just 6.8% had told their doctor. CONCLUSIONS: Findings suggest that the spike in IPV-related crime statistics following the onset of the pandemic (typically incidents of physical violence) is the tip of the iceberg for women's IPV experiences. There is a need to increase the capacity of health practitioners to recognise emotional as well as physical IPV, and IPV ought to be considered where women present with mental health problems.

Genomic characterization of Listeria monocytogenes recovered from dairy facilities in British Columbia, Canada from 2007 to 2017.

Listeria monocytogenes is a foodborne pathogen of concern in dairy processing facilities, with the potential to cause human illness and trigger regulatory actions if found in the product. Monitoring for Listeria spp. through environmental sampling is recommended to prevent establishment of these microorganisms in dairy processing environments, thereby reducing the risk of product contamination. To inform on L. monocytogenes diversity and transmission, we analyzed genome sequences of L. monocytogenes strains (n = 88) obtained through the British Columbia Dairy Inspection Program. Strains were recovered from five different dairy processing facilities over a 10 year period (2007-2017). Analysis of whole genome sequences (WGS) grouped the isolates into nine sequence types and 11 cgMLST types (CT). The majority of isolates (93%) belonged to lineage II. Within each CT, single nucleotide polymorphism (SNP) differences ranged from 0 to 237 between isolates. A highly similar (0-16 SNPs) cluster of over 60 isolates, collected over 9 years within one facility (#71), was identified suggesting a possible persistent population. Analyses of genome content revealed a low frequency of genes associated with stress tolerance, with the exception of widely disseminated cadmium resistance genes cadA1 and cadA2. The distribution of virulence genes and mutations within internalin genes varied across the isolates and facilities. Further studies are needed to elucidate their phenotypic effect on pathogenicity and stress response. These findings demonstrate the diversity of L. monocytogenes isolates across dairy facilities in the same region. Findings also showed the utility of using WGS to discern potential persistence events within a single facility over time.

The Childhood Resilience Study: Resilience and emotional and behavioural wellbeing experienced by Australian Aboriginal and Torres Strait Islander boys and girls aged 5-9 years.

BACKGROUND: Resilience is a process of drawing on internal or external strengths to regain, sustain or improve adaptive outcomes despite adversity. Using a child resilience measure co-designed with Aboriginal and Torres Strait Islander communities, we investigate: 1) children's personal, family, school and community strengths; 2) gender differences; and 3) associations between resilience and wellbeing. METHODS: 1132 parent/caregivers of children aged 5-12 years were recruited to the Childhood Resilience Study, including through the Aboriginal Families Study. The Aboriginal Families Study is a population-based cohort of 344 mothers of an Aboriginal and/or Torres Strait Islander child. This paper focuses on the wave 2 survey data on child resilience at age 5-9 years (n = 231). Resilience was assessed with the Child Resilience Questionnaire-parent/caregiver report (CRQ-P/C), categorised into tertiles of low, moderate and high scores. Child emotional/behavioural wellbeing and mental health competence was assessed with the parent-report Strengths and Difficulties Questionnaire. All Tobit regression models adjusted for child age. OUTCOMES: Aboriginal and Torres Strait Islander girls had higher resilience scores compared to boys (Adj.ß = 0·9, 95%CI 0·9-1·4), with higher School Engagement, Friends and Connectedness to language scale scores. Resilience scores were strongly associated with wellbeing and high mental health competence. A higher proportion of girls with low resilience scores had positive wellbeing than did boys (73.3% versus 49.0%). High resilience scores were associated with lower SDQ total difficulties score after adjusting for child age, gender, maternal age and education and family location (major city, regional, remote) (Adj.ß = -3.4, 95%CI -5.1, -1.7). Compared to the Childhood Resilience Study sample, Aboriginal Families Study children had higher mean CRQ-P/C scores in the personal and family domains. INTERPRETATION: High family strengths can support Aboriginal and Torres Strait Islander children at both an individual and cultural level. Boys may benefit from added scaffolding by schools, family and communities to support their social and academic connectedness.

A Systematic Scoping Review of Indigenous People's Experience of Healing and Recovery from Child Sexual Abuse.

Child sexual abuse is a form of violence that occurs across nations and cultures. Collective efforts are being made to address this issue within many Indigenous communities. In Australia, Aboriginal and Torres Strait Islander communities have expressed the need for cultural models of healing child sexual abuse. A preliminary exploration of the relevant literature shows a lack of synthesis with regard to the current evidence base. This protocol outlines the methods and background for a scoping review that aims to explore and collate the broad scope of literature related to healing from child sexual abuse within an Indigenous context. The proposed review utilises a 'population, concept, and context structure' from the Joanna Briggs Institute to explore the broad scope of the literature within a scoping review framework. The target population is Indigenous survivors of child sexual abuse, including Indigenous populations from six distinct regions: Aboriginal and Torres Strait Islander peoples from Australia; Maori peoples from Aotearoa (New Zealand); First Nations, Inuit and Métis peoples from Canada; Native American peoples from North America; Native peoples from Alaska; and the Sámi peoples of the Sápmi region in Northern Europe. The concept within the review is healing from an Indigenous perspective, which includes a broad range of processes related to both recovery and personal growth. The contexts explored within this review are any context in which healing from child sexual abuse can occur. This may include processes related to disclosure and accessing services, specific interventions or programs for survivors of child sexual abuse, as well as broader non-specific healing programs and personal experiences of healing without intervention. The scoping review will use search strings with broad inclusion and exclusion criteria to capture the potential breadth of perspectives. The search will be conducted across several academic databases and will also include an extensive search for grey literature. This protocol establishes the proposed benefits of this scoping review.

Understanding cannabis use and mental health difficulties in context with women's experiences of stressful events and social health issues in pregnancy: The Aboriginal Families Study.

BACKGROUND: Few population-based data sources fully recognise the intersections between stressful events, social health issues, and cannabis use in pregnancy, and little is known about sequelae for women's mental health. METHODS: We draw on two waves of population-based data for 344 families participating in the Aboriginal Families Study longitudinal cohort. We examine women's mental health in the first year postpartum and when children were aged 5-9 years in context with life experiences and use of cannabis in pregnancy. OUTCOMES: One in five women (19·5%) used cannabis during pregnancy (with or without co-use of tobacco). Within this group of women, 88·3% experienced 3 or more (3+) stressful events or social health issues. Psychological distress (Kessler-5 scale, K-5) in the year postpartum was substantially higher amongst women who had used cannabis or experienced 3+ stressful events or social health issues. High proportions of women met criteria for support and referral for depression and/or anxiety (52·5% of women who had used cannabis compared to 20·9% amongst women who had neither used cannabis nor tobacco; 43·2% of women who had experienced 3+ stressful events or social health issues compared to 15·6% amongst women who had not indicated these experiences). Similar patterns of psychological distress, depressive (9-item adapted Personal Health Questionnaire, aPHQ-9) and anxiety symptoms (7-item Generalised Anxiety Disorder score, GAD-7) were evident when the study children were aged 5-9 years. INTERPRETATION: Amongst women who had used cannabis in pregnancy, a high burden of psychological distress, depression, and anxiety is evident in the postpartum period and as their children turn 5-9 years. The overlay of stressful events and social health issues and the high proportion of women meeting criteria for referral for mental health assessment and support indicate an urgent need to offer women opportunities for safe disclosure of cannabis use and opportunities to access sustained holistic services. Reducing the harms of cannabis use on Aboriginal and Torres Strait Islander families must be coupled with culturally safe ways of addressing the social, historical, and structural determinants of mental health distress and harmful use of substances.

Creating shared goals and experiences as a pathway to peace.

Glowacki offers many new directions for understanding and even eliminating the problem of war, especially creating positive interdependencies with out-group members. We develop Glowacki's intriguing proposition that in-group dynamics provide a route to peace by describing a prosocial motivational system, the caregiving system, that aligns individual interests and eliminates the need to use coercion to achieve mutually beneficial outcomes.

Homelessness Among Acute Care Patients Within a Large Health Care System in Northern California.

The impacts of homelessness on health and health care access are detrimental. Intervention and efforts to improve outcomes and increase availability of affordable housing have mainly originated from the public health sector and government. The role that large community-based health systems may play has yet to be established. This study characterizes patients self-identified as homeless in acute care facilities in a large integrated health care system in Northern California to inform the development of collaborative interventions addressing unmet needs of this vulnerable population. The authors compared sociodemographic characteristics, clinical conditions, and health care utilization of individuals who did and did not self-identify as homeless and characterized their geographical distribution in relation to Sutter hospitals and homeless resources. Between July 1, 2019 and June 30, 2020, 5% (N = 20,259) of the acute care settings patients had evidence of homelessness, among which 51.1% age <45 years, 66.4% males, and 24% non-Hispanic Black. Patients experiencing homelessness had higher emergency department utilization and lower utilization of outpatient and urgent care services. Mental health conditions were more common among patients experiencing homelessness. More than half of the hospitals had >5% of patients who identified as homeless. Some hospitals with higher proportions of patients experiencing homelessness are not located near many shelter resources. By understanding patients who self-identify as homeless, it is possible to assess the role of the health system in addressing their unmet needs. Accurate identification is the first step for the health systems to develop and deliver better solutions through collaborations with nonprofit organizations, community partners, and government agencies.

The Pediatric Data Science and Analytics Subgroup of the Pediatric Acute Lung Injury and Sepsis Investigators Network: Use of Supervised Machine Learning Applications in Pediatric Critical Care Medicine Research.

OBJECTIVE: Perform a scoping review of supervised machine learning in pediatric critical care to identify published applications, methodologies, and implementation frequency to inform best practices for the development, validation, and reporting of predictive models in pediatric critical care. DESIGN: Scoping review and expert opinion. SETTING: We queried CINAHL Plus with Full Text (EBSCO), Cochrane Library (Wiley), Embase (Elsevier), Ovid Medline, and PubMed for articles published between 2000 and 2022 related to machine learning concepts and pediatric critical illness. Articles were excluded if the majority of patients were adults or neonates, if unsupervised machine learning was the primary methodology, or if information related to the development, validation, and/or implementation of the model was not reported. Article selection and data extraction were performed using dual review in the Covidence tool, with discrepancies resolved by consensus. SUBJECTS: Articles reporting on the development, validation, or implementation of supervised machine learning models in the field of pediatric critical care medicine. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 5075 identified studies, 141 articles were included. Studies were primarily (57%) performed at a single site. The majority took place in the United States (70%). Most were retrospective observational cohort studies. More than three-quarters of the articles were published between 2018 and 2022. The most common algorithms included logistic regression and random forest. Predicted events were most commonly death, transfer to ICU, and sepsis. Only 14% of articles reported external validation, and only a single model was implemented at publication. Reporting of validation methods, performance assessments, and implementation varied widely. Follow-up with authors suggests that implementation remains uncommon after model publication. CONCLUSIONS: Publication of supervised machine learning models to address clinical challenges in pediatric critical care medicine has increased dramatically in the last 5 years. While these approaches have the potential to benefit children with critical illness, the literature demonstrates incomplete reporting, absence of external validation, and infrequent clinical implementation.

Intimate partner violence exposure during infancy and social functioning in middle childhood: An Australian mother and child cohort study.

Social functioning of children with experiences of intimate partner violence (IPV) between caregivers in early childhood has received less attention than emotional-behavioral outcomes. Drawing on data from 1507 ten-year-old Australian-born children and their mothers participating in a community-based longitudinal study, this study examined the associations between IPV exposure during infancy and social development during middle childhood. IPV during the first 12 months of life was associated with lower social skills, higher peer problems, and peer victimization at age 10 years, while accounting for concurrent IPV. This study provides evidence for the long-term impacts of early-life IPV exposure on children's social functioning, and the importance of prevention and early intervention programs focused on social development following experiences of IPV.

Outcomes After Respiratory Extracorporeal Life Support in Teens and Young Adults: An Extracorporeal Life Support Organization Registry Analysis.

OBJECTIVES: A recent study from Germany found that survival after respiratory extracorporeal life support (ECLS) was lower among patients 10-20 years old than 20-30 years old. The objective of this study was to compare survival between teenage and young adult patients who receive respiratory ECLS. DESIGN: Retrospective cohort study. SETTING: Extracorporeal Life Support Organization registry, an international prospective quality improvement database. PATIENTS: All patients ages 16-30 years cannulated for respiratory indications from 1990 to 2020 were included. Patients were divided into two groups, teens (16-19 yr old) and young adults (20-30 yr old). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcome was survival to discharge. Variables were considered for the multivariate logistic regression model if there was both a statistically significant difference (p ≤ 0.05) and a clinically meaningful absolute difference between the groups. A total of 5,751 patients were included, of whom 1,653 (29%) were teens and 4,098 (71%) were young adults. Survival to discharge was higher in young adults than teens, 69% versus 63% (p < 0.001). Severity of illness was higher among teens; however, survival within each stratum defined by Pao2/Fio2 ratio was higher in young adults than in teens. Use of venoarterial ECLS was higher in teens than in young adults, 15% versus 7%, respectively. Teens were more likely to receive high-frequency oscillatory ventilation and this therapy was associated with a longer time from admission to ECLS initiation. After adjusting for variables that differ significantly between the groups, the odds ratio for survival in young adults compared with teens was 1.14 (95% CI, 1.004-1.3). CONCLUSIONS: In this large multicenter retrospective study, mortality was higher in teens than in young adults who received respiratory ECLS. This difference persisted after adjusting for multiple variables and the mechanism underlying these findings remains unclear.

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.

Protection against lung pathology during obesity-accelerated ageing in mice by the parasitic worm product ES-62.

Mice develop pathology in the lungs as they age and this may be accelerated by a high calorie diet (HCD). ES-62 is a protein secreted by the parasitic worm Acanthocheilonema viteae that is immunomodulatory by virtue of covalently attached phosphorylcholine (PC) moieties. In this study, we show that weekly treatment of C57BL/6J mice with ES-62 protected against pathology in the lungs in male but not female mice fed a HCD from 10 weeks of age as shown by reductions in cellular infiltration and airway remodelling, particularly up to 160 days of age. ES-62 also reduced gene expression of the cytokines IL-4 and IL-17 and in addition the TLR/IL-1R adaptor MyD88, in the lungs of male mice although HCD-induced increases in these inflammatory markers were not detected until between 340 and 500 days of age. A combination of two drug-like ES-62 PC-based small molecule analogues (SMAs), produced broadly similar protective effects in the lungs of male mice with respect to both lung pathology and inflammatory markers, in addition to a decrease in HCD-induced IL-5 expression. Overall, our data show that ES-62 and its SMAs offer protection against HCD-accelerated pathological changes in the lungs during ageing. Given the targeting of Th2 cytokines and IL-17, we discuss this protection in the context of ES-62's previously described amelioration of airway hyper-responsiveness in mouse models of asthma.

Financial Sustainability of Novel Delivery Models in Behavioral Health Treatment.

BACKGROUND: In the US, much of the research into new intervention and delivery models for behavioral health care is funded by research institutes and foundations, typically through grants to develop and test the new interventions. The original grant funding is typically time-limited. This implies that eventually communities, clinicians, and others must find resources to replace the grant funding -otherwise the innovation will not be adopted. Diffusion is challenged by the continued dominance in the US of fee-for-service reimbursement, especially for behavioral health care. AIMS: To understand the financial challenges to disseminating innovative behavioral health delivery models posed by fee-for-service reimbursement, and to explore alternative payment models that promise to accelerate adoption by better addressing need for flexibility and sustainability. METHODS: We review US experience with three specific novel delivery models that emerged in recent years. The models are: collaborative care model for depression (CoCM), outpatient based opioid treatment (OBOT), and the certified community behavioral health clinic (CCBHC) model. These examples were selected as illustrating some common themes and some different issues affecting diffusion. For each model, we discuss its core components; evidence on its effectiveness and cost-effectiveness; how its dissemination was funded; how providers are paid; and what has been the uptake so far. RESULTS: The collaborative care model has existed for longest, but has been slow to disseminate, due in part to a lack of billing codes for key components until recently. The OBOT model faced that problem, and also (until recently) a regulatory requirement requiring physicians to obtain federal waivers in order to prescribe buprenorphine. Similarly, the CCBHC model includes previously nonbillable services, but it appears to be diffusing more successfully than some other innovations, due in part to the approach taken by funders. DISCUSSION: A common challenge for all three models has been their inclusion of services that were not (initially) reimbursable in a fee-for-service system. However, even establishing new procedure codes may not be enough to give providers the flexibility needed to implement these models, unless payers also implement alternative payment models. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: For providers who receive time-limited grant funding to implement these novel delivery models, one key lesson is the need to start early on planning how services will be sustained after the grant ends. IMPLICATIONS FOR HEALTH POLICY: For research funders (e.g., federal agencies), it is clearly important to speed up the process of obtaining coverage for each novel delivery model, including the development of new billable service codes, and to plan for this as early as possible. Funders also need to collaborate with providers early in the grant period on sustainability planning for the post-grant environment. For payers, a key lesson is the need to fold novel models into stable existing funding streams such as Medicaid and commercial insurance coverage, rather than leaving them at the mercy of revolving time-limited grants, and to provide pathways for contracting for innovations under new payment models. IMPLICATIONS FOR FURTHER RESEARCH: For researchers, a key recommendation would be to pay greater attention to the payment environment when designing new delivery models and interventions.

Diversity, equity, and inclusion correlates of racial/ethnic harassment and discrimination in the U.S. military.

As one of the most racially/ethnically diverse workplaces in the United States, the Department of Defense (DoD) has been on the forefront in driving diversity initiatives. Yet, racial/ethnic harassment and discrimination (REHD) in the military persist and threaten mission readiness. Despite this, limited research exists identifying factors that influence REHD in the U.S. military that could be leveraged for prevention and intervention. In this study, we sought to identify how diversity, equity, and inclusion (DEI) factors in the workplace are associated with REHD in order to identify potential targets for prevention and policy efforts to improve racial/ethnic relations in the U.S. military. Using the 2017 Workplace and Equal Opportunity Survey of Active Duty Members, we found military, leadership, and unit DEI climate factors were the top predictors of REHD, though the relative importance of each predictor varied by racial/ethnic minority status. In particular, we found military and leadership attention to REHD to be the top predictors for Racial/Ethnic Minority active duty members whereas workplace hostility was the top predictor for non-Hispanic White active duty members. Implications for programs and policies surrounding REHD in the U.S. military are discussed.
