Virtual communities of practice (VCoPs) can decrease social, structural, and professional isolation, provide opportunities for knowledge-sharing abilities, and may improve participants' self-reported sense of connectedness to one another and their profession. However, more research is needed to examine measurement of VCoPs effectiveness on participants. In this scoping review our research question was: What is the state of the science for VCoPs and how are these communities measured in current research specific to education and health/health education? Guided by Arksey and O'Malley's five stages for conducting a rigorous scoping review, we identified gaps in the evidence regarding the overall state of the science on measurement of VCoPs inclusive of quantitative and mixed-methods literature describing validated VCoP measurement in both English or Spanish from January 1990 to July 2023, and within the health, education, or health education disciplines. Initial searches yielded 2350 articles. Authors independently screened papers and extracted data. The results of this scoping review (N = 13 articles) highlight the measurement of VCoPs specific to education, healthcare, health education research. We found that measures had been tested in VCoPs within health, education, health education, and professional education information technologies disciplines, with the Community of Inquiry framework being the most common theoretical foundation. The findings provide an understanding of measurement tools and impacts and outcomes of VCoP participation and we make recommendations for future VCoP measurement tool development.

Objectives were (a) to understand a community-informed narrative, as told by community members (CMs) and community partners (CPs), about the strengths, experiences, and perspectives of public housing communities; and (b) to analyze similarities and differences between CMs' and CPs' experiences and perspectives. Qualitative interviews were conducted with 22 CMs of public housing (ages 26–58, 100% female caregivers, 96% Black, 4% multiethnic) and 43 CPs (ages 28–78, 67.4% female, 81.4% Black and African American). Four themes were derived from the CM and CP interviews: (1) counters to public narratives, (2) disinvestment begets disinvestment, (3) community conditions should be better, and (4) community cohesion and connection. Findings from this study present community-centered narratives and experiences that were counter to stereotyped public narratives and could influence public perceptions and behavior to inform policy changes related to improving living conditions and supporting CMs in public and low-income housing communities.

Peer support, defined as the social and emotional support offered and received by individuals with a shared experience of mental health difficulties, is gaining popularity in youth mental health settings. This systematic scoping review aimed to collate and synthesise the evidence on key aspects of peer support interventions within integrated youth services and educational settings. Specifically, it synthesised evidence on the (1) assessed mental health outcomes in peer support interventions, (2) key characteristics and associated roles of peer support workers (PSWs) and (3) barriers and facilitators to implementation. A search of peer reviewed articles from January 2005 to June 2022 across five electronic databases (PsychINFO, Pubmed, Scopus, ERIC and CINAHL) was conducted. A total of 15 studies retrieved in the search met the inclusion criteria and were included in the review. This review supports previous research indicating that peer support has potential for improving recovery related outcomes. While a variety of interventions and PSW roles were reported, studies could be strengthened by providing more in-depth information on intervention content. Examples of barriers to implementation included staff concerns around confidentiality of peer support relationships as well as PSWs' confidence in their roles. Facilitators included positive support from staff members and role clarity.

Strengthening interorganizational collaboration is critical to mitigate the impact of adverse childhood experiences (ACEs) and improve community health. We examined change in interorganizational collaboration around ACEs within Peace4Tarpon's network and investigated factors influencing collaboration. We conducted a community-wide social network analysis among 32 trauma-informed organizations in 2016 and 2018, using network analysis methods to examine interorganizational cohesion (density, transitivity, triad census) over time, and multiple regression quadratic assignment procedure to investigate factors influencing collaboration. Network cohesion measures indicated small increases in collaboration level and greater network cohesion over time. Conducting ACEs screenings was a significant factor (b = 0.237; p < 0.01) predicting likelihood of interorganizational collaboration in 2016. No assessed ACEs practices predicted collaboration in 2018, suggesting variables assessed predicted a small proportion of variance in collaboration change. Results provide a foundation for understanding how ACEs/trauma-informed practices influence collaboration and highlight implications of interorganizational collaboration. Peace4Tarpon's 2-year progress provides insights for other trauma-informed communities.

Understanding the effects of inflammation and cirrhosis on the regulation of drug metabolism during the progression of hepatocellular carcinoma (HCC) is critical for developing patient-specific treatment strategies. In this work, we created novel three-dimensional vascularized HCC-on-a-chips (HCCoC), composed of HCC, endothelial, stellate, and Kupffer cells tuned to mimic normal or cirrhotic liver stiffness. HCC inflammation was controlled by tuning Kupffer macrophage numbers, and the impact of cytochrome P450-3A4 (CYP3A4) was investigated by culturing HepG2 HCC cells transfected with CYP3A4 to upregulate expression from baseline. This model allowed for the simulation of chemotherapeutic delivery methods such as intravenous injection and transcatheter arterial chemoembolization (TACE). We showed that upregulation of metabolic activity, incorporation of cirrhosis and inflammation, increase vascular permeability due to upregulated inflammatory cytokines leading to significant variability in chemotherapeutic treatment efficacy. Specifically, we show that further modulation of CYP3A4 activity of HCC cells by TACE delivery of doxorubicin provides an additional improvement to treatment response and reduces chemotherapy-associated endothelial porosity increase. The HCCoCs were shown to have utility in uncovering the impact of the tumor microenvironment (TME) during cancer progression on vascular properties, tumor response to therapeutics, and drug delivery strategies.

The current study aimed to identify profiles of youth presenting with a unique combination of environmental characteristics and understand the differential relationship between profile membership, anxiety, and depression symptoms. Data were drawn from 158 Latino youth between the ages of 11 and 13. Youth provided information on community violence exposure, acculturative stress, familial and peer support, and parental supervision. Main analyses included Latent Profile Analysis and Multivariate Analysis of Variance. Support for a four-profile model was found. Profiles are distinguished by mean levels of community violence exposure, acculturative stress, familial and peer support, and parental supervision. Profile membership was significantly associated with anxiety and depression, separately. Those belonging to the profile with the highest levels of environmental risk reported the highest levels of anxiety and depression. Findings contribute to a personalized understanding of risk and protective experiences in the environment for Latino youth.

In this study, we examined how school policies and strategies (i.e., positive discipline, hardening strategies, and positive behavioral strategies) affect teacher relational factors and teacher reports of victimization and safety. Specifically, we examined the mediational roles of teacher support of student learning, maltreatment of students by teachers, and teachers' differential treatment of students in schools. Using a sample of 6643 pre-K-12th-grade teachers, path analysis results revealed that positive behavior strategies, hardening strategies, and positive discipline were indirectly associated with teacher victimization and sense of safety. Additionally, teachers' perceptions of other teachers maltreating students had the greatest contributions to their sense of safety and victimization by students. Positive discipline was directly and indirectly associated with teacher victimization and safety. Implications and directions for future studies are discussed.
