RESUMO
BACKGROUND: The shape and size of skeletal elements is determined by embryonic patterning mechanisms as well as localized growth and remodeling during post-embryonic development. Differential growth between endochondral growth plates underlies many aspects of morphological diversity in tetrapods but has not been investigated in ray-finned fishes. We examined endochondral growth rates in the craniofacial skeletons of two cichlid species from Lake Malawi that acquire species-specific morphological differences during postembryonic development and quantified cellular mechanisms underlying differential growth both within and between species. RESULTS: Cichlid endochondral growth rates vary greatly (50%-60%) between different growth zones within a species, between different stages for the same growth zone, and between homologous growth zones in different species. Differences in cell proliferation and/or cell enlargement underlie much of this differential growth, albeit in different proportions. Strikingly, differences in extracellular matrix production do not correlate with growth rate differences. CONCLUSIONS: Differential endochondral growth drives many aspects of craniofacial morphological diversity in cichlids. Cellular proliferation and enlargement, but not extracellular matrix deposition, underlie this differential growth and this appears conserved in Osteichthyes. Cell enlargement is observed in some but not all cichlid growth zones and the degree to which it occurs resembles slower growing mammalian growth plates.

COVID-19 led to widespread disruption of services that promote family well-being. Families impacted most were those already experiencing disparities due to structural and systemic barriers. Existing support systems faded into the background as families became more isolated. New approaches were needed to deliver evidence-based, low-cost interventions to reach families within communities. We adapted a family strengthening intervention developed in Kenya ("Tuko Pamoja") for the United States. We tested a three-phase participatory adaptation process. In phase 1, we conducted community focus groups including 11 organizations to identify needs and a community partner. In phase 2, the academic-community partner team collaboratively adapted the intervention. We held a development workshop and trained community health workers to deliver the program using an accelerated process combining training, feedback, and iterative revisions. In phase 3, we piloted Coping Together with 18 families, collecting feedback through session-specific surveys and participant focus groups. Community focus groups confirmed that concepts from Tuko Pamoja were relevant, and adaptation resulted in a contextualized intervention-"Coping Together"-an 8-session virtual program for multiple families. As in Tuko Pamoja, communication skills are central and applied for developing family values, visions, and goals. Problem-solving and coping skills then equip families to reach goals, while positive emotion-focused activities promote openness to change. Sessions are interactive, emphasizing skills practice. Participants reported high acceptability and appropriateness, and focus groups suggested that most content was understood and applied in ways consistent with the theory of change. The accelerated reciprocal adaptation process and intervention could apply across resource-constrained settings.
RESUMO
Collaboration with African religious congregations can promote psychosocial well-being with greater accessibility. Effective collaboration requires studying congregations as unique intervention contexts. This study explored how an intervention in western Kenya fit within and altered congregational discussion patterns. We conducted a cluster-randomized trial of a church-based intervention to improve family relationships, mental health and sexual health. For each intervention topic covered, we describe baseline and post-intervention changes in church leaders' beliefs and communication as well as discussion frequency between leaders and members and among members. Mixed-effects logistic regression assessed pre-post change in member-reported discussion frequency. At baseline, members and leaders reported already discussing family, parenting, and emotions frequently and sexuality and finances less frequently. Leaders generally felt they should discuss all topics but were less comfortable and knowledgeable about sexuality and finances than other topics. After the intervention, leader comfort and knowledge increased and discussion frequency increased for nearly all topics, especially those discussed less initially. Good fit between the desires and activities of church members and leaders suggests the potential for further collaboration, especially on mental health and family well-being. Increased discussion of sensitive topics underscores the potential of community-level interventions to affect social norms.

RESUMO
Intimate partner violence (IPV) is a global public health crisis with long-term adverse consequences for both victims and perpetrators. Patterns of violence often begin during adolescence, yet most interventions target adult relationships. A systematic review was conducted to identify correlates of IPV victimization and perpetration among adolescents and young adults in sub-Saharan Africa (SSA). Eligible studies included participants 10 to 24 years old, took place in SSA, and tested a statistical association between a correlate and an IPV outcome. Correlates were defined as any condition or characteristic associated with statistically significant increased or decreased risk of IPV victimization or perpetration. PsycInfo, PubMed, Embase, and African Index Medicus were searched and included studies published between January 1, 2000 and February 4, 2022. The search resulted in 3,384 original studies, of which 55 met inclusion criteria and were analyzed. Correlates were first qualitatively synthesized by developmental period (e.g., early adolescence, older adolescence, and young adulthood) and then organized in a conceptual framework by correlate type (e.g., socio-demographic; health, behavior, and attitudes; relational; or contextual). Over two decades of literature reveals variability in evidence by developmental period but also substantial overlap in the correlates of victimization and perpetration. This review identifies multiple points for intervention and results suggest the urgent need for earlier, developmentally appropriate prevention efforts among younger adolescents as well as combined approaches that target both victimization and perpetration of IPV.

In this pilot study, we tested a virtual family strengthening and mental health promotion intervention, Coping Together (CT), during the COVID-19 pandemic. We explored changes at the family and individual levels, as well as mechanisms of change. Participants included 18 families (24 caregivers, 24 youth) with children aged 7 to 18 years. Community health workers delivered the 8-session CT intervention using videoconferencing software. We used qualitative semi-structured interviews with 14 of the families to explore changes and mechanisms of change using a thematic content analysis approach. We also administered pre-post surveys with the 18 families to explore the direction of changes, using only descriptive statistics in this small sample. Qualitative findings supported positive changes across family and individual level outcomes including family functioning, relationship quality, and individual psychosocial well-being. Results also confirmed several hypothesized mechanisms of change with improved communication providing the foundation for increased hope and improved problem solving and coping. Pre-post survey results were mixed, showing positive, but very small, changes in family closeness, caregiver-child communication, and levels of hope; almost no change was observed on measures of caregiver and child mental health. Families reported few problems at baseline quantitatively despite qualitative descriptions of pre-intervention difficulties. Results provide preliminary support for benefits of CT with the most consistent improvements seen across family relationships. Findings were mixed related to individual-level mental health benefits. Results have implications for revising content on mental health coping strategies and suggest the need to revise the quantitative measurement strategy for this non-clinical sample.

Structural barriers perpetuate mental health disparities for minoritized US populations; global mental health (GMH) takes an interdisciplinary approach to increasing mental health care access and relevance. Mutual capacity building partnerships between low and middle-income countries and high-income countries are beginning to use GMH strategies to address disparities across contexts. We highlight these partnerships and shared GMH strategies through a case series of said partnerships between Kenya-North Carolina, South Africa-Maryland, and Mozambique-New York. We analyzed case materials and narrative descriptions using document review. Shared strategies across cases included: qualitative formative work and partnership-building; selecting and adapting evidence-based interventions; prioritizing accessible, feasible delivery; task-sharing; tailoring training and supervision; and mixed-method, hybrid designs. Bidirectional learning between partners improved the use of strategies in both settings. Integrating GMH strategies into clinical science-and facilitating learning across settings-can improve efforts to expand care in ways that consider culture, context, and systems in low-resource settings.
RESUMO
Background: Long-term use of inhaled corticosteroids (ICSs) is associated with several potential adverse effects. While patients unlikely to benefit should stop ICS use, abrupt discontinuation may result in an increased risk of chronic obstructive pulmonary disease (COPD) exacerbation. Stepwise tapering may reduce this risk but data are limited, and there is no consensus on the likelihood of COPD exacerbations following ICS discontinuation. The North Texas Veterans Affairs Health Care System conducted a single center, retrospective cohort study to evaluate the rate of COPD exacerbations following the discontinuation of ICS therapy using different schedules of discontinuation. Methods: Data were collected from the electronic health records of patients aged ≥ 40 years with a diagnosis of COPD who were on a stable dose of an ICS for ≥ 1 year that was subsequently discontinued with a last documented fill date between January 10, 2021 and September 1, 2021. Eligible patients were followed for COPD exacerbations that resulted in hospitalization until November 1, 2022. Descriptive statistics were used to evaluate characteristics of patients who experienced an exacerbation. Results: Seventy-five patients were included: 5 (7%) experienced an exacerbation following ICS discontinuation. Age, sex, race, and ethnicity were similar for those patients who did vs did not have an exacerbation. Unexpectedly, the mean baseline eosinophil count for patients with an exacerbation was 92 cells/µL compared with 227.4 cells/µL for those without an exacerbation. Nine patients had their ICS tapered gradually, and none of them experienced an exacerbation. Conclusions: Study findings suggest that there is a relatively low risk of COPD exacerbation following ICS discontinuation, regardless of whether a taper was performed. This result may indicate that it is reasonable to abruptly discontinue ICS in eligible patients.
RESUMO
BACKGROUND: In March 2020, the novel 2019 coronavirus disease (COVID-19) was declared a pandemic. In May 2020, George Floyd was murdered, catalyzing a national racial reckoning. In the Southern United States, these events occurred in the context of a history of racism and high rates of poverty and discrimination, especially among racially and ethnically minoritized populations. OBJECTIVES: In this study, we examine social vulnerabilities, the perceived impacts of COVID-19 and the national racial reckoning, and how these are associated with depression symptoms in the South. METHODS: Data were collected from 961 adults between June and November 2020 as part of an online survey study on family well-being during COVID-19. The sample was majority female (87.2%) and consisted of 661 White participants, 143 Black participants, and 157 other racial and ethnic minoritized participants. Existing social vulnerability, perceived impact of COVID-19 and racial violence and protests on families, and depressive symptoms were assessed. Hierarchical regression analysis was used to predict variance in depressive symptoms. RESULTS: Half of the sample (52%) reported a negative impact of COVID-19, and 66% reported a negative impact of national racial violence/protests. Depressive symptoms were common with 49.8% meeting the cutoff for significant depressive symptoms; Black participants had lower levels of depressive symptoms. Results from the hierarchical regression analysis indicate social vulnerabilities and the perceived negative impact of COVID-19 and racial violence/protests each contribute to variance in depressive symptoms. Race-specific sensitivity analysis clarified distinct patterns in predictors of depressive symptoms. CONCLUSION: People in the South report being negatively impacted by the confluence of the COVID-19 pandemic and the emergence of racial violence/protests in 2020, though patterns differ by racial group. These events, on top of pre-existing social vulnerabilities, help explain depressive symptoms in the South during 2020.
RESUMO
Children in conflict-affected settings are at increased risk for exposure to violence, placing particular importance on caregiving environments. This study first describes parenting in urban Liberia by evaluating parent-child interactions, the use and acceptance of harsh and nonharsh discipline, discipline preferences, and the co-occurrence of positive interactions and harsh discipline. The relationship between parenting stress and harsh discipline attitudes and behaviors is then tested. Participants included 813 parents with a child aged 3 or 4 years old. A quantitative survey battery assessed parent-child interactions; discipline practices, preferences, and attitudes; and parenting stress. Parents reported frequent use and high acceptance of nonharsh discipline, as well as frequent positive interactions with their child. Though parents reported less frequent use and low acceptance of harsh discipline, preference for harsh discipline-based on hypothetical situations rather than self-report-was common. There was co-occurrence of frequent positive interactions and frequent harsh discipline, with one third reporting high frequency of both. Regression analysis revealed greater parenting stress (ß = .15, t = 4.49, p < .001) and stronger acceptance of harsh discipline (ß = .47, t = 15.49, p < .001) were associated with more frequent harsh discipline. Acceptance of harsh discipline interacted with parenting stress to predict the use of harsh discipline (ß = -.09, t = -3.09, p < .01). Among parents with lowest average acceptance of harsh practices, stress predicted more frequent harsh discipline, but acceptance did not moderate the association for those who are most accepting of harsh practices. Building on existing parenting strengths and addressing parenting stress could promote nurturing caregiving in conflict-affected settings.

BACKGROUND: Problem drinking and co-occurring depression symptoms affect men at high rates and are associated with increased risk of family violence. In low- and middle-income countries, there is a large treatment gap for services due to a lack of human resources. Moreover, masculine norms are a barrier to men seeking treatment for drinking and depression in healthcare settings. We examined an approach for engaging peer-fathers to deliver an intervention to reduce alcohol use, improve depressive symptoms, and increase family involvement among fathers in Kenya with problem drinking. The intervention-LEAD (Learn, Engage, Act, Dedicate)-combines motivational interviewing, behavioral activation, and masculinity discussion strategies. METHODS: Community and religious leaders nominated fathers with no mental health training to serve as counselors (N=12); clients were recruited through community referrals. Nominated fathers completed a 10-day training beginning with treatment principles followed by manualized content. Three counselors were selected after training based on quantitative and qualitative assessments of communication skills, intervention knowledge, willingness to learn, ability to use feedback, and empathy. Supervision was tiered with local supervisors and clinical psychologist consultation. During LEAD delivery, counselor fidelity, delivery quality, and general and intervention-specific competencies were assessed. To evaluate acceptability, qualitative interviews were conducted with lay-counselors and clients (N=11). Descriptive statistics were calculated for quantitative outcomes; interviews were analyzed using thematic analysis. RESULTS: Peer-father lay counselors treated nine clients, with eight completing treatment. Counselors reached high rates of fidelity (93.8%) and high to optimal ratings on quality of delivery, clinical competency, and intervention-specific competencies. Qualitative results suggested high acceptability, with counselors expressing satisfaction and empowerment in their roles. Clients likewise described positive experiences with counselors. CONCLUSIONS: Findings provide initial support for the acceptability and feasibility of recruitment, selection, and training processes for peer-father lay counselors to deliver LEAD through a lens of masculinity that aligned with clients help-acceptance practices.

BACKGROUND: Despite a sustained focus by policymakers and researchers on improving the standard of clinical care in public mental health services, the use of evidence-based practice remains low. Among other challenges, this reflects the difficulty of translating clinical research into useable policy that can be feasibly funded and monitored by state or large healthcare systems. CASE PRESENTATION: In this paper we present a case study of Washington State's strategy for monitoring the use of clinical elements at the session level for all Medicaid-funded children's mental health services. The implementation of this strategy reflects policy actions to promote effective practice while also actively influencing multiple other levels of the implementation ecology. The approach is informed by the Policy Ecology Framework, the Consolidated Framework for Implementation Research, the evidence-based policymaking literature, and common ontology and clinical elements models. CONCLUSIONS: We found the strategy developed in Washington State to be a feasible method of collecting session level information about the use of effective clinical mental health practices. In addition, the approach appears to be having influence on multiple layers of the implementation ecology that could be explored through further study.
