RESUMO

BACKGROUND: Community violence is a persistent and challenging public health problem. Community violence not only physically affects individuals, but also its effects reverberate to the well-being of families and entire communities. Being exposed to and experiencing violence are adverse community experiences that affect the well-being and health trajectories of both children and adults. In the United States, community violence has historically been addressed through a lens of law enforcement and policing; the impact of this approach on communities has been detrimental and often ignores the strengths and experiences of community members. As such, community-centered approaches to address violence are needed, yet the process to design, implement, and evaluate these approaches is complex. Alternatives to policing responses are increasingly being implemented. However, evidence and implementation guidance for community-level public health approaches remain limited. This study protocol seeks to address community violence through a resilience framework-Adverse Community Experiences and Resilience (ACE|R)-being implemented in a major US city and leveraging a strategy of community organizing to advance community violence prevention. OBJECTIVE: The objective of this research is to understand the impact of community-level violence prevention interventions. Furthermore, we aim to describe the strategies of implementation and identify barriers to and facilitators of the approach. METHODS: This study uses a hybrid type 1 effectiveness-implementation design. Part 1 of the study will assess the effectiveness of the ACE|R framework plus community organizing by measuring impacts on violence- and health-related outcomes. To do so, we plan to collect quantitative data on homicides, fatal and nonfatal shootings, hospital visits due to nonaccidental injuries, calls for service, and other violence-related data. In Part 2 of the study, to assess the implementation of ACE|R plus community organizing, we will collect process data on community engagement events, deliver community trainings on community leadership and organizing, and conduct focus groups with key partners about violence and violence prevention programs in Milwaukee. RESULTS: This project received funding on September 1, 2020. Prospective study data collection began in the fall of 2021 and will continue through the end of 2023. Data analysis is currently underway, and the first results are expected to be submitted for publication in 2024. CONCLUSIONS: Community violence is a public health problem in need of community-centered solutions. Interventions that center community and leverage community organizing show promise in decreasing violence and increasing the well-being of community members. Methods to identify the impact of community-level interventions continue to evolve. Analysis of outcomes beyond violence-specific outcomes, including norms and community beliefs, may help better inform the short-term and proximal impacts of these community-driven approaches. Furthermore, hybrid implementation-effectiveness trials allow for the inevitable contextualization required to disseminate community interventions where communities drive the adaptations and decision-making.

RESUMO

Current literature lacks clear examples of how to engage with communities in the development of opioid misuse interventions for diverse populations and across various settings. The National Institutes of Health (NIH) Helping to End Addiction Long-term® Initiative (HEAL) Prevention Cooperative (HPC) research projects work collaboratively with communities to develop and adapt their opioid misuse interventions to increase both feasibility and sustainability. Ten HPC projects were selected to receive NIH funding and are required to have partnerships with communities where their intervention is being conducted. This paper applies the Centers for Disease Control and Prevention (CDC)-adapted Public Participation Framework to examine the levels of community engagement used by each of these 10 HPC projects (Clinical and Translational Science Awards Consortium Community Engagement Key Function Committee Task Force on the Principles of Community Engagement, 2015). Using this framework, this paper illustrates the range of community engagement approaches and levels that the HPC projects rely on to develop, adapt, and adopt opioid prevention interventions across diverse populations and settings. This paper also lays a foundation for future examinations of the role of community engagement in intervention implementation and effectiveness and the level of community engagement that is necessary to improve intervention effectiveness.

RESUMO

This supplemental issue describes the individual studies and collaborative efforts of the Helping to End Addiction Long-term Prevention Cooperative's (HPC's) innovative approaches to rapidly develop evidence-based prevention programs for widespread dissemination. This introduction succinctly reviews (1) the context that demands the rapid development of efficacious prevention programs and their scale-ups, (2) the unique objectives of the individual HPC research projects, and (3) collective efforts to harmonize research across studies to advance the prevention of opioid misuse and gain insight into opioid misuse etiology to inform improvements in preventive interventions. At the conclusion of HPC studies, we anticipate the availability of multiple evidence-based programs to prevent opioid misuse and use disorder for persons who experience particular sources of risk and for delivery in settings where prevention has traditionally been lacking. By harmonizing and coordinating efforts across 10 distinct outcomes studies of prevention programs and making data available for analysis by non-HPC researchers, the HPC's efficacy and etiology evidence will far surpass the additive contributions of 10 individual research projects.

RESUMO

BACKGROUND: Social capital is increasingly recognized as a key component of adolescent development, providing important opportunities to grow and strengthen their social networks while increasing access to resources such as jobs and social support. OBJECTIVES: This study explored how youth-serving organizations (YSOs) across California address social capital development and assessed need for a social capital curriculum or measurement tools. METHODS: The sample for this study was drawn from the 2019 IRS Business Master File from the National Center for Charitable Statistics Data Archive. We contacted a random sample of 169 California YSOs and implemented a 15-item survey to capture organizational perspectives on the importance of social capital, tools to measure this construct, and the use of programming related to social capital. RESULTS: Among 41 YSOs completing the survey, only 24 (59%) had heard of the term "social capital," but when the term was described, 88% felt it was a highly important asset for youth. Thirty YSOs (73%) provided programming designed to promote social capital. Most respondents (68%) said being able to measure social capital would be very important and nearly all said they would be interested in adopting a tested social capital curriculum. CONCLUSIONS: Strong interest from YSOs for additional social capital tools highlights the need for additional work in this area. With support, YSOs can connect young people to institutions and influencers significantly outside of normal social circles, thus creating an increasingly sustainable and diverse range of resources available to youth as they navigate life milestones.

RESUMO

METHODS: We used a Boolean search strategy of PubMed, PsycINFO, and Embase to identify eligible publications from January 1990 to March 2020 and narrative analysis to synthesize the evidence. RESULTS: The database search identified 1267 independent citations; 29 publications met inclusion criteria. Nearly all the studies demonstrated high risk of bias, most often due to selection and confounding bias. Most of the studies in the review (k = 20, 69%) found at least one significant association between social connection and opioid outcomes. Although no two studies included the same measures of social connection or opioid misuse, and social connection was both positively and negatively associated with opioid misuse, results support that social connection is an important correlate of opioid misuse. CONCLUSIONS: This review highlights the importance of social connection as a correlate to opioid misuse. However, the extensive variability among research studies points to a need for standardization of measurement and larger studies with diverse populations to allow for consequential recommendations for prevention or treatment of opioid misuse. Evidence regarding the associations between social connection and opioid misuse or disorder is sparse. We provide suggestions for advancing this research, including clarification of the complex influences between social connections and opioid misuse.

RESUMO

This prospective cost analysis addresses a gap in the prevention literature by providing estimates of the typical real-world costs to implement community interventions focused on preventing underage drinking and prescription drug misuse. The study uses cost data reported by more than 400 community subrecipients participating in a national cross-site evaluation of the Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success grant program during 2013-2017. Community subrecipient organizations completed an annual Web-based survey to report their intervention costs. The analysis compares the relative startup and annual ongoing implementation costs of different prevention strategies and services. Partnerships for Success communities implemented a wide variety of interventions. Annual ongoing implementation was typically more costly than intervention startup. Costs were generally similar for population-level interventions, such as information dissemination and environmental strategies, and individual-level interventions, such as prevention education and positive alternative activities. However, population-level interventions reached considerably more people and consequently had much lower costs per person. Personnel contributed the most to intervention costs, followed by intervention supplies and overhead. Startup costs for initial training and costs for incentives, ongoing training, and in-kind contributions (nonlabor) during ongoing implementation were not typically reported. This study informs prevention planning by providing detailed information about the costs of classes of interventions used in communities, outside of research settings.

RESUMO

The Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success (PFS) program supports community-based organizations (CBOs) across the United States in implementing evidence-based prevention interventions to reduce substance use in adolescents and young adults. Little attention has been paid to how CBOs combine interventions to create comprehensive community-specific prevention approaches, or whether different approaches achieve similar community-level effects on prescription drug misuse (PDM). We used PFS evaluation data to address these gaps. Over 200 CBOs reported their prevention intervention characteristics, including strategy type (e.g., prevention education, environmental strategies) and number of unique interventions. Evaluation staff coded whether each intervention was an evidence-based program, practice, or policy (EBPPP). Latent Class Analysis of seven characteristics (use of each of five strategy types, use of one or more EBPPP, and number of interventions implemented) identified six prevention approach profiles: High Implementation EBPPP, Media Campaigns, Environmental EBPPP, High Implementation Non-EBPPP, Prevention Education, and Other Information Dissemination. All approaches except Media Campaigns and Other Information Dissemination were associated with significant reductions in community-level PDM. These approaches may need to be paired with other, more direct, prevention activities to effectively reduce PDM at the community level. However, similar rates of change in PDM across all 6 prevention approaches suggests only weak evidence favoring use of the other four approaches. Community-based evaluations that account for variability in implemented prevention approaches may provide a more nuanced understanding of community-level effects. Additional work is needed to help CBOs identify the most appropriate approach to use based on their target communities' characteristics and resources.

RESUMO

The emerging dual threats of underaged drinking (UAD) and prescription drug misuse (PDM) require sustained prevention efforts across multiple levels of interventions. In response to the continuing proliferation of UAD and PDM among youth and young adults, the Substance Abuse and Mental Health Services Administration (SAMHSA) developed the Partnerships for Success (PFS) program. Across five cohorts funded from 2012 to 2016, PFS created linkages between health care providers, treatment and prevention services providers, government agencies, and nonprofit organizations for the delivery of multiple sets of services (e.g., prevention education, community activities, screening) targeted toward UAD and PDM. This paper reports on the impact of the PFS program on reductions in ethanol and prescription drug poisoning exposures as reported from data in the National Poisoning Data System (NPDS). Across 35 States, communities targeted by PFS interventions were compared to non-targeted communities using a non-equivalent comparison groups design and propensity score weighting. Using propensity-weighted, multilevel latent growth modeling, steeper reductions in ethanol and prescription drug poisoning exposure call rates were observed in States which had a higher proportion of communities participating in PFS. Grantee-level longitudinal analogs to Cohen's d effect sizes ranged from -0.24 to -0.97, whereas PFS' effects on individual communities (net of Statewide effects) were negligible. The study serves as a unique exemplar of using the NPDS to extract community-level intervention effects that might otherwise be "hidden" within epidemiological data while underscoring the cumulative effects of PFS' community-level efforts in stemming the tide on underaged drinking and prescription drug misuse.

RESUMO

Prevention science researchers and practitioners are increasingly engaged in a wide range of activities and roles to promote evidence-based prevention practices in the community. Ethical concerns invariably arise in these activities and roles that may not be explicitly addressed by university or professional guidelines for ethical conduct. In 2015, the Society for Prevention Research (SPR) Board of Directors commissioned Irwin Sandler and Tom Dishion to organize a series of roundtables and establish a task force to identify salient ethical issues encountered by prevention scientists and community-based practitioners as they collaborate to implement evidence-based prevention practices. This article documents the process and findings of the SPR Ethics Task Force and aims to inform continued efforts to articulate ethical practice. Specifically, the SPR membership and task force identified prevention activities that commonly stemmed from implementation and scale-up efforts. This article presents examples that illustrate typical ethical dilemmas. We present principles and concepts that can be used to frame the discussion of ethical concerns that may be encountered in implementation and scale-up efforts. We summarize value statements that stemmed from our discussion. We also conclude that the field of prevention science in general would benefit from standards and guidelines to promote ethical behavior and social justice in the process of implementing evidence-based prevention practices in community settings. It is our hope that this article serves as an educational resource for students, investigators, and Human Subjects Review Board members regarding some of the complexity of issues of fairness, equality, diversity, and personal rights for implementation of preventive interventions.

RESUMO

Over a decade ago, the Society for Prevention Research endorsed the first standards of evidence for research in preventive interventions. The growing recognition of the need to use limited resources to make sound investments in prevention led the Board of Directors to charge a new task force to set standards for research in analysis of the economic impact of preventive interventions. This article reports the findings of this group's deliberations, proposes standards for economic analyses, and identifies opportunities for future prevention science. Through examples, policymakers' need and use of economic analysis are described. Standards are proposed for framing economic analysis, estimating costs of prevention programs, estimating benefits of prevention programs, implementing summary metrics, handling uncertainty in estimates, and reporting findings. Topics for research in economic analysis are identified. The SPR Board of Directors endorses the "Standards of Evidence for Conducting and Reporting Economic Evaluations in Prevention Science."

RESUMO

Boys and men of color are exposed to traumatic experiences at significantly higher rates than are other demographic groups. To understand and address the mental and behavioral health effects of trauma, including violent incidents, on this population, we review the literature showing the context for, outcomes of, and potential responses to trauma exposure. We present the existing research about the unique challenges and associated negative outcomes for boys and men of color, as well as identify the gaps in the literature. We present the potential nurturing responses by systems such as schools, law enforcement, and communities to trauma-exposed boys and men of color, and we describe evidence-based programs and practices that directly address trauma. Finally, we argue that, rather than using a deficit model, a model of optimal development can be used to understand how to support and protect boys and men of color through nurturing environments.

RESUMO

Concepts of culture and diversity are necessary considerations in the scientific application of theory generation and developmental processes of preventive interventions; yet, culture and/or diversity are often overlooked until later stages (e.g., adaptation [T3] and dissemination [T4]) of the translational science process. Here, we present a conceptual framework focused on the seamless incorporation of culture and diversity throughout the various stages of the translational science process (T1-T5). Informed by a community-engaged research approach, this framework guides integration of cultural and diversity considerations at each phase with emphasis on the importance and value of "citizen scientists" being research partners to promote ecological validity. The integrated partnership covers the first phase of intervention development through final phases that ultimately facilitate more global, universal translation of changes in attitudes, norms, and systems. Our comprehensive model for incorporating culture and diversity into translational research provides a basis for further discussion and translational science development.

RESUMO

CTP-499 is a novel oral multi-subtype selective inhibitor of PDEs that is currently in clinical testing, in combination with angiotensin modulators, as a potentially first-in-class treatment for diabetic kidney disease. The compound was discovered and developed by using Concert's proprietary DCE Platform(®) in which deuterium was incorporated at select positions of 1-((S)-5-hydroxyhexyl)-3,7-dimethylxanthine (HDX). CTP-499 metabolizes to five major metabolites: C-21256, D-M2, D-M3, D-M4 and M5, of which all contains deuterium except M5. During in vivo metabolism, however, H/D exchange takes place. As a result, each analyte, except M5, has multiple molecular masses. To accurately quantify the analytes, we developed an LC-MS/MS method focusing on the core structures of the molecules, termed "core-structure analyses". The core-structure analyses method was then validated under GLP guidance in dog, rat and rabbit plasma, with a sample volume of 50 µL. Results demonstrated that this approach accurately quantifies each of the six analytes despite partial exchange of deuterium with hydrogen atoms in the in vivo samples. The validation parameters included accuracy, precision, sensitivity, stability, dilution integrity, hemolysis, matrix effect, selectivity, and recovery. Acceptable intra-run and inter-run assay precision (%CV ≤ 5.5%) and accuracy (90.1-106.7%) were achieved over a linear range of 10-5,000 ng/mL of each analyte. Various stability tests, including bench-top, freeze/thaw, stock solution, and long-term storage, were also performed. All stability results met acceptance criteria. The robustness of the methods was demonstrated by the incurred sample reproducibility (ISR) tests. After validation, the method was successfully used in support of multiple toxicological studies of CTP-499.

RESUMO

OBJECTIVE: To determine whether the molecular epidemiological characteristics of methicillin-resistant Staphylococcus aureus (MRSA) had changed in a level III neonatal intensive care unit (NICU). DESIGN: Retrospective review of medical records. SETTING: Level III NICU of a university-affiliated children's hospital in New York, New York. PATIENTS: Case patients were neonates hospitalized in the NICU who were colonized or infected with MRSA. METHODS: Rates of colonization and infection with MRSA during the period from 2000 through 2008 were assessed. Staphylococcal chromosomal cassette (SCC) mecA analysis and genotyping for S. aureus encoding protein A (spa) were performed on representative MRSA isolates from each clonal pulsed-field gel electrophoresis pattern. RESULTS: Endemic MRSA infection and colonization occurred throughout the study period, which was punctuated by 4 epidemiologic investigations during outbreak periods. During the study period, 93 neonates were infected and 167 were colonized with MRSA. Surveillance cultures were performed for 1,336 neonates during outbreak investigations, and 115 (8.6%) neonates had MRSA-positive culture results. During 2001-2004, healthcare-associated MRSA clones, carrying SCC mec type II, predominated. From 2005 on, most MRSA clones were community-associated MRSA with SCC mec type IV, and in 2007, USA300 emerged as the principal clone. CONCLUSIONS: Molecular analysis demonstrated a shift from healthcare-associated MRSA (2001-2004) to community-associated MRSA (2005-2008).

RESUMO

Sociotechnical theory has been used to inform the development of computer systems in the complex and dynamic environment of healthcare. The key components of the sociotechnical system are the workers, their practices, their mental models, their interactions, and the tools used in the work process. We conducted a sociotechnical analysis of a neonatal intensive care unit towards the development of decision support for antimicrobial prescribing. We found that the core task was to save the baby in the face of complex and often incomplete information. Organizational climate characteristics were pride in clinical and educational practice. In addition, the structure of work identified interdisciplinary teamwork with some communication breakdown and interruptive work environment. Overall, sociotechnical analysis provided a solid method to understand work environment during the decision support development process.

RESUMO

Sepsis in neonates is a significant problem that carries with it severe morbidity and mortality. Managing antibiotics in this population is therefore an important issue. We studied clinical alerts currently in place to support antibiotic prescribing in a neonatal intensive care unit in order to ensure that appropriate information is being provided in a way that is consistent with current recommendations. Data were obtained from our alerts tracking database. Alerts were described according to triggering orders and clinician recipients. We found that alerts most commonly associated with antibiotics are providing critical information regarding lab results and patient factors necessary in preventing adverse effects of these drugs. Clinician recipients of alerts are those responsible for entering orders and the information is being provided at the point of care.

RESUMO

Computerized provider order entry (CPOE) with decision support is an important tool for addressing preventable medication errors. However, reports of poorly designed systems have shown an increase in adverse events. As part of a project aimed at designing a decision support system for antibiotic prescribing, a sociotechnical approach was used to understand the environment where CPOE is used in a neonatal intensive care unit (NICU). Themes identified included pride in practice, teamwork and collaboration, information integration, and a constantly changing environment.

RESUMO

The carbothermal reduction of silica into silicon requires the use of temperatures well above the silicon melting point (> or =2,000 degrees C). Solid silicon has recently been generated directly from silica at much lower temperatures (< or =850 degrees C) via electrochemical reduction in molten salts. However, the silicon products of such electrochemical reduction did not retain the microscale morphology of the starting silica reactants. Here we demonstrate a low-temperature (650 degrees C) magnesiothermic reduction process for converting three-dimensional nanostructured silica micro-assemblies into microporous nanocrystalline silicon replicas. The intricate nanostructured silica microshells (frustules) of diatoms (unicellular algae) were converted into co-continuous, nanocrystalline mixtures of silicon and magnesia by reaction with magnesium gas. Selective magnesia dissolution then yielded an interconnected network of silicon nanocrystals that retained the starting three-dimensional frustule morphology. The silicon replicas possessed a high specific surface area (>500 m(2) g(-1)), and contained a significant population of micropores (< or =20 A). The silicon replicas were photoluminescent, and exhibited rapid changes in impedance upon exposure to gaseous nitric oxide (suggesting a possible application in microscale gas sensing). This process enables the syntheses of microporous nanocrystalline silicon micro-assemblies with multifarious three-dimensional shapes inherited from biological or synthetic silica templates for sensor, electronic, optical or biomedical applications.
