Implementation and evaluation of a community-based mindful walking randomized controlled trial to sustain cognitive health in older African Americans at risk for dementia.

BACKGROUND: With an increasing proportion of older adults and the associated risk of Alzheimer's Disease and Related Dementias (ADRD) around the globe, there is an urgent need to engage in ADRD risk reduction efforts. African American (AA) older adults in the U.S. are disproportionally impacted by ADRD compared to other races and ethnicities. Mindful walking integrates two potentially protective factors of ADRD by elevating mindfulness and physical activity (i.e., walking), resulting in a synergistic behavioral strategy that is feasible and safe for older adults. However, the efficacy of applying this intervention for cognitive health outcomes has not been evaluated using experimental designs. METHODS: This paper documents the goal and protocol of a community-based, mindful walking randomized controlled trial to examine the short- and longer-term efficacy on cognitive and other health-related outcomes in ADRD at-risk AA older adults. The study outcomes include various brain health determinants, including cognitive function, quality of life, psychological well-being, physical activity, mindfulness, sleep, and overall health status. In addition, the estimated costs of program implementation are also collected throughout the study period. This study will recruit 114 older adults (ages 60+ years) with elevated ADRD risk from the Midlands region of South Carolina. Older adults are randomly assigned to participate in 24 sessions of outdoor mindful walking over three months or a delayed mindful walking group (n=57 in each group). Participants in both groups follow identical measurement protocols at baseline, after 12 weeks, after 18 weeks, and after 24 weeks from baseline. The outcome measures are administered in the lab and in everyday settings. Costs per participant are calculated using micro-costing methods. The eliciting participant costs for mindful walking engagement with expected results are reported using the payer and the societal perspectives. DISCUSSION: This study will generate evidence regarding the efficacy of mindful walking on sustaining cognitive health in vulnerable older adults. The results can inform future large-scale effectiveness trials to support our study findings. If successful, this mindful walking program can be scaled up as a low-cost and viable lifestyle strategy to promote healthy cognitive aging in diverse older adult populations, including those at greatest risk.

[Facilitators and barriers to the implementation of health promotion in daycare centers and elementary schools based on four selected projects]. / Gelingens- und Hindernisfaktoren bei der Implementierung von Gesundheitsförderung in Kitas und Grundschulen anhand von 4 ausgewählten Projekten.

BACKGROUND: Health promotion (HP) is a complex, politically required task. The quality of implementation correlates with the effectiveness of health promotion initiatives. Successful implementation requires consideration of contextual conditions, which tend to be neglected in effectiveness studies. The aim is to identify success factors and obstacles to the implementation of HP in daycare centers and elementary schools based on 4 projects (Fit fürs Leben, fit für pisa +, Buchprojekt Sonnige Traurigtage, and The Daily Mile) in the Göttingen/South Lower Saxony region. The effects of the COVID-19 pandemic are assumed to be relevant for the implementation of these projects. METHODS: In 24 semi-structured interviews and 2 focus group discussions between August 2021 and March 2022, practitioners were asked about the implementation of the four projects in their areas of activity. After transcription, the interviews were analyzed using qualitative content analysis. The Consolidated Framework for Implementation Research supported the analysis. RESULTS: A total of 22 groups of factors were identified, on the basis of which 22 recommendations for action for GF implementation were formulated. Success factors at the individual and intervention level were at the forefront. The COVID-19 pandemic had a positive impact on the importance of HP, even though its feasibility was hampered. DISCUSSION: Numerous findings on the implementation of HP in children's living environments were confirmed by the study. The high significance of the individual factors is striking, which could be due to the survey of interviewees being familiar with the projects. The study results contribute to the further development of implementation strategies in HP.

Feasibility and acceptability of using biometric fingerprinting to track migrations and support retention in HIV prevention research in fishing population in East Africa.

INTRODUCTION: Fishing populations constitute a suitable key population amongst which to conduct HIV prevention trials due to very high HIV prevalence and incidence, however, these are highly mobile populations. We determined the feasibility and acceptability of using fingerprinting and geographical positioning systems to describe mobility patterns and retention among fisherfolks on the shoreline of Lake Victoria in South-western Uganda. METHODS: Between August 2015 and January 2017, two serial cross-sectional surveys were conducted during which fingerprinting of all residents aged 18-30 years on the shoreline of Lake Victoria was done. A mapper moving ahead of the survey team, produced village maps and took coordinates of every household. These were accessed by the survey team that assigned household and individual unique identifiers (ID) and collected demographic data. Using the assigned IDs, individuals were enrolled and their fingerprints scanned. The fingerprinting was repeated 6 months later in order to determine the participant's current household. If it was different from that at baseline, a new household ID was assigned which was used to map migrations both within and between villages. RESULTS: At both rounds, over 99% accepted to be fingerprinted. No fingerprinting faults were recorded at baseline and the level was under 1% at round two. Over 80% of the participants were seen at round two and of these, 16.3%, had moved to a new location whilst the majority, 85%, stayed within the same village. Movements between villages were mainly observed for those resident in large villages. Those who did not consider a fishing village to be their permanent home were less likely to be migrants than permanent residents (adjusted odds ratio = 0.37, 95%CI:0.15-0.94). CONCLUSION: Use of fingerprinting in fishing populations is feasible and acceptable. It is possible to track this mobile population for clinical trials or health services using this technology since most movements could be traced within and between villages.

Learning Through Doing: Comprehensive Programming for a Training Program in Cancer Disparities.

In the United States, preparing researchers and practitioners for careers in cancer requires multiple components for success. In this reflection article, we discuss our approach to designing a comprehensive research training program in cancer disparities. We focused on elements that provide students and early career scientists a deep understanding of disparities through first-hand experiences and skills training necessary to build a research career in the area. Our Educational Program sits within the framework of an NCI P20 program, "UHAND (University of Houston/MD Anderson Cancer Center)", jointly established by an NCI-designated comprehensive cancer center and a minority-serving university as a collaborative partnership devoted to the elimination of cancer inequities among disproportionately affected racial and ethnic groups (UHAND Program to Reduce Cancer Disparities; NCI P20CA221696/ P20CA221697). The Education Program was designed to build on and enhance skills that are critical to pursuing a career in cancer disparities research at the undergraduate, doctoral, and post-doctoral levels-such as scientific communication, career planning and development, professional and community-based collaboration, and resilience in addition to solid scientific training. As such, our program integrates (1) opportunities for learning through service to community organizations providing resources to populations with documented cancer disparities, (2) a tailored curriculum of learning activities with program leadership and mentored research with scientists focused on cancer disparities and cancer prevention, (3) professional development training critical to career success in disparities research, and (4) support to address unique challenges faced by trainees from backgrounds that are historically underrepresented in research.

NIH Primary and Secondary Prevention Research in Humans: a Portfolio Analysis of Study Designs Used in 2012-2019.

We can learn a great deal about the research questions being addressed in a field by examining the study designs used in that field. This manuscript examines the research questions being addressed in prevention research by characterizing the distribution and trends of study designs included in primary and secondary prevention research supported by the National Institutes of Health through grants and cooperative agreements, together with the types of prevention research, populations, rationales, exposures, and outcomes associated with each type of design. The Office of Disease Prevention developed a taxonomy to classify new extramural NIH-funded research projects and created a database with a representative sample of 14,523 research projects for fiscal years 2012-2019. The data were weighted to represent the entirety of the extramural research portfolio. Leveraging this dataset, the Office of Disease Prevention characterized the study designs proposed in NIH-funded primary and secondary prevention research applications. The most common study designs proposed in new NIH-supported prevention research applications during FY12-19 were observational designs (63.3%, 95% CI 61.5%-65.0%), analysis of existing data (44.5%, 95% CI: 42.7-46.3), methods research (23.9%, 95% CI: 22.3-25.6), and randomized interventions (17.2%, 95% CI: 16.1%-18.4%). Observational study designs dominated primary prevention research, while intervention designs were more common in secondary prevention research. Observational designs were more common for exposures that would be difficult to manipulate (e.g., genetics, chemical toxin, and infectious disease (not pneumonia/influenza or HIV/AIDS)), while intervention designs were more common for exposures that would be easier to manipulate (e.g., education/counseling, medication/device, diet/nutrition, and healthcare delivery). Intervention designs were not common for outcomes that are rare or have a long latency (e.g., cancer, neurological disease, Alzheimer's disease) and more common for outcomes that are more common or where effects would be expected earlier (e.g., healthcare delivery, health related quality of life, substance use, and medication/device). Observational designs and analyses of existing data dominated, suggesting that much of the prevention research funded by NIH continues to focus on questions of association and on questions of identification of risk and protective factors. Randomized and non-randomized intervention designs were included far less often, suggesting that a much smaller fraction of the NIH prevention research portfolio is focused on questions of whether interventions can be used to modify risk or protective factors or to change some other health-related biomedical or behavioral outcome. The much heavier focus on observational studies is surprising given how much we know already about the leading risk factors for death and disability in the USA, because those risk factors account for 74% of the county-level mortality in the USA, and because they play such a vital role in the development of clinical and public health guidelines, whose developers often weigh results from randomized trials much more heavily than results from observational studies. Improvements in death and disability nationwide are more likely to derive from guidelines based on intervention research to address the leading risk factors than from additional observational studies.

Open Science and Intervention Research: a Program Developer's and Researcher's Perspective on Issues and Concerns.

Open Science practices bear great promise for making research in general more reproducible and transparent, and these goals are very important for preventive intervention research. From my perspective as a program co-developer, I note potential concerns and issues of how open science practices can be used in intervention research. Key issues considered are in the realms of pre-registration (making pre-registration a living document; providing rewards for hypothesis-generating research, in addition to hypothesis-testing research), data archiving (resources for data archiving of large datasets; ethical issues related to need for strong de-identification), and research materials (intervention manuals and materials, and characteristics, training and supervision of intervention staff). The paper focuses on easier-to-address and considerably harder-to-address issues and concerns in these three areas.

Ethical considerations for involving adolescents in biomedical HIV prevention research.

BACKGROUND: Involvement of adolescent girls in biomedical HIV research is essential to better understand efficacy and safety of new prevention interventions in this key population at high risk of HIV infection. However, there are many ethical issues to consider prior to engaging them in pivotal biomedical research. In Uganda, 16-17-year-old adolescents can access sexual and reproductive health services including for HIV or other sexually transmitted infections, contraception, and antenatal care without parental consent. In contrast, participation in HIV prevention research involving investigational new drugs requires adolescents to have parental or guardian consent. Thus, privacy and confidentiality concerns may deter adolescent participation. We describe community perspectives on ethical considerations for involving adolescent girls in the MTN 034 study in Uganda. METHODS: From August 2017 to March 2018, we held five stakeholder engagement meetings in preparation for the MTN 034 study in Kampala, Uganda (NCT03593655): two with 140 community representatives, two with 125 adolescents, and one with 50 adolescents and parents. Discussions were moderated by the study team. Proceedings were documented by notetakers. Summary notes described community perspectives of adolescent participation in HIV research including convergent, divergent or minority views, challenges, and proposed solutions. RESULTS: Most community members perceived parental or guardian consent as a principal barrier to study participation due to concerns about adolescent disclosure of pre-marital sex, which is a cultural taboo. Of 125 adolescent participants, 119 (95%) feared inadvertent disclosure of sexual activity to their parents. Community stakeholders identified the following critical considerations for ethical involvement of adolescents in HIV biomedical research: (1) involving key stakeholders in recruitment, (2) ensuring confidentiality of sensitive information about adolescent sexual activity, (3) informing adolescents about information to be disclosed to parents or guardians, (4) offering youth friendly services by appropriately trained staff, and (5) partnering with community youth organizations to maximize recruitment and retention. CONCLUSIONS: Stakeholder engagement with diverse community representatives prior to conducting adolescent HIV prevention research is critical to collectively shaping the research agenda, successfully recruiting and retaining adolescents in HIV clinical trials and identifying practical strategies to ensure high ethical standards during trial implementation.

Health behaviors and related disparities of insured adults with a health care provider in the United States, 2015-2016.

Health care providers are in a unique position to address patients' health behaviors and social determinants of health, factors like income and social support that can significantly impact health. There is a need to better understand the risk behaviors of a population that providers may counsel (i.e., those who are insured and have a provider.) Using the 2015 and 2016 CDC's Behavioral Risk Factor Surveillance System, we examine the prevalence of health behaviors and the existence of disparities in health behaviors based on social determinants among American adults. Our sample included noninstitutionalized adults aged 18 to 64 years, in the U.S. (N > 300,000). We used multivariate logistic regression analysis to assess the independent effects of income, education, sex, race, and metropolitan status on nine key health behaviors. Among adults with insurance and a provider (n > 200,000): 1) rates of engaging in poor health behaviors ranged from 6.4% (heavy drinking) to 68.1% (being overweight or obese), 2) rural residence, lower income, and lower education were associated with decreased clinical preventive services, 3) lower income and lower education were associated with lifestyle-related risks, and 4) being black was associated with receiving more cancer screenings, no influenza vaccination, inadequate physical activity, and being overweight or obese. Insured adults, with a provider, are not meeting recommended guidelines for health behaviors. Significant disparities in health behaviors related to social factors exist among this group. Health care providers and organizations may find it helpful to consider these poor health behaviors and disparities when determining strategies to address SDOH.

Ethical complexities of responding to bystander risk in HIV prevention trials.

Till Bärnighausen points out the medical risks that two categories of contemporary HIV prevention trials, for "treatment-as-prevention" and for "pre-exposure prophylaxis," pose to people who are not study participants. Bärnighausen's compelling case forces reconsideration of the absence of bystanders in the law governing ethical review of health research. It raises the intriguing question: to what legal protection are bystanders morally entitled? The remedy might seem to be to accord bystanders the rights and protections currently accorded to human study participants. We counsel against that remedy on three grounds, inviting colleagues to suggest alternatives.

Tailoring an Alcohol Intervention for American Indian Alaska Native Women of Childbearing Age: Listening to the Community.

BACKGROUND: Reduction of risky drinking in women of childbearing age is 1 strategy that may be employed to prevent fetal alcohol spectrum disorder, a sequela of prenatal alcohol exposure. Communities differ in risk and protective factors, necessitating culturally informed interventions for maximal efficacy. This article describes the modification of an existing web-based screening, brief intervention, and referral to treatment intervention to reduce risky drinking among American Indian Alaska Native (AIAN) women of childbearing age in Southern California into a peer-to-peer-based intervention using motivational interviewing (MI). METHODS: The modification process was iterative and included various community focus groups, interviews, and a final review. RESULTS: Intervention modification was required for cultural congruence. Components of the peer-to-peer intervention designed by this project included a flip chart used to guide the motivational interviewing, charts of the financial and physical costs of alcohol consumption, revised baseline and follow-up questionnaires, and guidance regarding the application of MI techniques. CONCLUSIONS: This study may inform the modification of future interventions among AIAN communities.

A Culturally Sensitive Approach to Large-Scale Prevention Studies: A Case Study of a Randomized Controlled Trial With Low-Income Latino Communities.

In response to U.S. federal mandates to increase the presence of underrepresented populations in prevention research, investigators have increasingly focused on using culturally sensitive research practices. However, scholars have rarely discussed these practices in terms of a larger culturally sensitive framework. Further, while the literature has explored how culturally sensitive approaches can be employed in a variety of methods, there has been little examination of how to incorporate such approaches into experimental designs. In this paper, we explain how we incorporated a culturally sensitive framework in a cluster randomized field trial with over 3000 predominantly low-income Latino families, utilizing an intervention designed to improve social relations and enhance family functioning. We offer conceptual and practical examples to guide other researchers who want to adopt a similar approach in their research designs. In addition, we discuss the benefits of forging local partnerships throughout the research process to ensure respect for racial and ethnic minorities participating in social and behavioral experimental studies. We conclude with practical considerations for utilizing a culturally sensitive framework to advance prevention programs, policies, and practices among underrepresented groups in order to achieve the ultimate goal of addressing the traditional underrepresentation of racial and ethnic minorities in research.

A discrete-time survival model with random effects for designing and analyzing repeated low-dose challenge experiments.

Repeated low-dose (RLD) challenge designs are important in HIV vaccine research. Current methods for RLD designs rely heavily on an assumption of homogeneous risk of infection among animals, which, upon violation, can lead to invalid inferences and underpowered study designs. We propose to fit a discrete-time survival model with random effects that allows for heterogeneity in the risk of infection among animals and allows for predetermined challenge dose changes over time. Based on this model, we derive likelihood ratio tests and estimators for vaccine efficacy. A two-stage approach is proposed for optimizing the RLD design under cost constraints. Simulation studies demonstrate good finite sample properties of the proposed method and its superior performance compared to existing methods. We illustrate the application of the heterogeneous infection risk model on data from a real simian immunodeficiency virus vaccine study using Rhesus Macaques. The results of our study provide useful guidance for future RLD experimental design.

Audit of workplace walkability in an Irish healthcare setting.

Recent studies suggest that time spent sitting is associated with greater risks of all causes of mortality and cardiovascular disease even for those who live a healthy lifestyle. As part of a healthier worksite initiative, we conducted a worksite walkability audit and staff survey of a large hospital-based administrative campus with a high proportion of health staff working in largely office-based roles. The US Centre for Disease Control (CDC) Healthier Worksite Initiative Walkability Audit Tool was used to audit 20 walking segments. The audit further examined the walkability of segments most likely to be used by outpatients and the families of residents visiting and attending the campus. The second phase of this research involved an employee electronic survey to understand staff requirements from a workplace physical activity initiative. Overall, the campus scored a medium risk to walkability on the CDC audit tool. This means that with some key minor alterations the walking route could be made safe and attractive for walking. There was a 20% (n = 151) response rate to the staff survey with 66% of respondents sitting at their desk for most of the day with the majority spending 5-7 h a day sitting at work. Evidence suggests that reducing sedentary time may be important to public health. The worksite is an ideal location for targeting a large number of individuals. Key public health messages that promote daily recommended physical activity targets should also carry additional messages about reducing occupational sitting time.

A Balancing Act: Integrating Evidence-Based Knowledge and Cultural Relevance in a Program of Prevention Parenting Research with Latino/a Immigrants.

Family therapists have a unique opportunity to contribute toward the reduction of widespread mental health disparities impacting diverse populations by developing applied lines of research focused on cultural adaptation. For example, although evidence-based prevention parent training (PT) interventions have been found to be efficacious with various Euro-American populations, there is a pressing need to understand which specific components of PT interventions are perceived by ethnic minority parents as having the highest impact on their parenting practices. Equally important is to examine the perceived cultural relevance of adapted PT interventions. This qualitative investigation had the primary objective of comparing and contrasting the perceived relevance of two culturally adapted versions of the efficacious parenting intervention known as Parent Management Training, the Oregon Model (PMTO). According to feasibility indicators provided by 112 Latino/a immigrant parents, as well as findings from a qualitative thematic analysis, the core parenting components across both adapted interventions were identified by the majority of research participants as relevant to their parenting practices. Participants exposed to the culturally enhanced intervention, which included culture-specific sessions, also reported high satisfaction with components exclusively focused on cultural issues that directly impact their parenting practices (e.g., immigration challenges, biculturalism). This investigation illustrates the relevant contributions that family therapy scholars can offer toward addressing mental health disparities, particularly as it refers to developing community-based prevention interventions that achieve a balance between evidence-based knowledge and cultural relevance.

Spatial Analysis Methods for Health Promotion and Education.

This article provides a review of spatial analysis methods for use in health promotion and education research and practice. Spatial analysis seeks to describe or make inference about variables with respect to the places they occur. This includes geographic differences, proximity issues, and access to resources. This is important for understanding how health outcomes differ from place to place; and in terms of understanding some of the environmental underpinnings of health outcomes data by placing it in context of geographic location. This article seeks to promote spatial analysis as a viable tool for health promotion and education research and practice. Four more commonly used spatial analysis techniques are described in-text. An illustrative example of motor vehicle collisions in a large metropolitan city is presented using these techniques. The techniques discussed are as follows: descriptive mapping, global spatial autocorrelation, cluster detection, and identification and spatial regression analysis. This article provides useful information for health promotion and education researchers and practitioners seeking to examine research questions from a spatial perspective.

Preventing alcohol-exposed pregnancy among an American Indian/Alaska Native population: effect of a screening, brief intervention, and referral to treatment intervention.

BACKGROUND: Fetal alcohol spectrum disorders are the result of alcohol-exposed pregnancies (AEP) and believed to be the leading known cause of developmental disabilities in the United States. Our objective was to determine whether a culturally targeted Screening, Brief Intervention, and Referral to Treatment (SBIRT) intervention may reduce risky drinking and vulnerability to AEP among American Indian/Alaska Native (AIAN) women in Southern California. METHODS: Southern California AIAN women of childbearing age who completed a survey including questions regarding alcohol consumption and contraceptive use were randomized into intervention or treatment as usual groups where the former group completed an online SBIRT intervention, and were followed up at 1, 3, and 6 months postintervention. RESULTS: Of 263 women recruited and 247 with follow-up data, one-third were at high risk of having an AEP at baseline. Both treatment groups decreased self-reported risky drinking behavior (drinks per week, p < 0.001; frequency of heavy episodic [binge] drinking episodes per 2 weeks, p = 0.017 and risk of AEP p < 0.001 at 6 months postintervention) in the follow-up period. There was no difference between treatment groups. Baseline factors associated with decreased risk of an AEP at follow-up included the perception that other women in their peer group consumed a greater number of drinks per week, having reported a greater number of binge episodes in the past 2 weeks, and depression/impaired functionality. CONCLUSIONS: Participation in assessment alone may have been sufficient to encourage behavioral change even without the web-based SBIRT intervention. Randomization to the SBIRT did not result in a significantly different change in risky drinking behaviors. The importance of perception of other women's drinking and one's own depression/functionality may have implications for future interventions.

Public health and prevention research within the Medical Research Future Fund.

OBJECTIVE: To explore the amount and type of research funded under relevant Medical Research Future Fund (MRFF) Initiatives that addressed public health and prevention from 2018 to July 2023. METHODS: Projects funded by six MRFF Initiatives, with objectives relevant to public health and public health nominated as "field of research" by >25% of applicants, were evaluated against a set of public health research criteria and were categorised based on levels of prevention. RESULTS: Fifty-seven per cent of 249 funded projects were categorised as public health research. Projects with curative features, focusing on tertiary (32%) and quaternary (4%) prevention, were as common as projects with earlier preventive features, focussed on primordial (7%) and primary (28%) prevention. The Preventive and Public Health Research Initiative had the lowest proportion of public health research (48%) of the six evaluated Initiatives and a dominance of curative (39%) and non-preventive (26%) research over preventive research (30%). CONCLUSION: This study highlighted variable levels of public health research across public-health-relevant MRFF Initiatives and generally low proportions of primary and primordial prevention. A greater emphasis on primordial and primary prevention research in public-health-relevant Initiatives could advance prevention in Australia. IMPLICATIONS FOR PUBLIC HEALTH: There appears to be scope for improvement in the prioritisation of upstream prevention research in public-health-relevant MRFF Initiatives and projects. Addressing this may enhance the benefit of MRFF to Australian public health.

Engagement of vulnerable communities in HIV prevention research in India: a qualitative investigation.

BACKGROUND: Meaningful community engagement (CE) in HIV prevention research is crucial for successful and ethically robust study implementation. We conducted a qualitative study to understand the current CE practices in HIV prevention research and to identify expressed and implicit reasons behind translational gaps highlighted by communities and researchers. METHODS: For this exploratory qualitative study, we recruited a purposive sample of participants from Indian government-recognised key populations such as men who have sex with men, transgender women, people who inject drugs and female sex workers; general population adults and adolescents/youth; and researchers. We conducted 13 virtual focus groups (n = 86) between July and October 2021. Data were explored from a critical realist perspective and framing analysis (i.e., examining how the participants framed the narratives). RESULTS: Participants reported that study communities, especially those from key populations, were primarily involved in data collection, but not necessarily with optimal training. Involvement of communities before the start of the study (e.g., obtaining feedback on the study's purpose/design) or once the study is completed (e.g., sharing of findings) were highlighted as priorities for meaningful engagement. Participants suggested meaningful CE in all stages of the study: (1) before the study-to get inputs in finalising the study design, drafting comprehensible informed consent forms and culturally-appropriate data collection tools, and deciding on appropriate monetary compensation; (2) during the study-adequate training of community field research staff; and (3) after the study-sharing the draft findings to get community inputs, and involving communities in advocacy activities towards converting evidence into action, policy or programs. Timely and transparent communications with communities were explicitly stated as critical for gaining and maintaining trust. Mutual respect, reciprocity (e.g., appropriate monetary compensation) and robust community feedback mechanisms were considered critical for meaningful CE. CONCLUSIONS: The findings highlighted the translational gaps and priority areas for capacity building to strengthen CE in HIV prevention research. It is not only important to engage communities at various stages of research but to understand that trust, dignity, respect, and reciprocity are fundamentally preferred ways of meaningful community engagement.

Engaging communities in HIV prevention research enhances the rigour and impact of research. We sought to understand the current community engagement practices and to identify how communities preferred to get involved in research. We explored these topics with key and general populations and researchers, by conducting 13 focus group discussions with 86 participants. We found that there was limited involvement of communities before the start of the study and after its completion, although trained community members were involved in data collection. Participants strongly suggested that the community should be involved throughout­before initiation, during the study and after study completion. Participants' preferred ways of engaging communities reflected that mutual respect, reciprocity and transparent communications are critical for meaningful and successful community engagement.

CD2 glycoprotein and CD44 structure and prevention of diabetes nephropathy: Central characteristics of related genes based on WGCNA and PPI.

Diabetic nephropathy (DN) is a prevalent complication of diabetes mellitus, characterized by complex pathogenesis that involves numerous molecules and signaling pathways. Among these, CD2 glycoprotein and CD44 play pivotal roles in cell adhesion, signal transduction, and inflammatory responses, potentially contributing significantly to the onset and progression of DN. This study aimed to investigate the central features of CD2 glycoprotein and CD44 in preventing diabetic nephropathy. To achieve this, kidney tissue sample data from DN patients were sourced from a public gene expression database. The roles of CD2 glycoprotein and CD44 within the PPI network were then analyzed, focusing on their interactions with other related genes. WGCNA analysis identified several significant gene modules associated with DN, including CD2 glycoprotein and CD44. PPI network analysis showed that these two proteins had a high degree of connectivity in the network, suggesting that they may be central regulatory molecules of DN. Further functional enrichment analysis revealed the potentially important role of CD2 glycoprotein and CD44 in diabetic nephropathy.

Enablers and Inhibitors to Implementing Tobacco Cessation Interventions within Homeless-Serving Agencies: A Qualitative Analysis of Program Partners' Experiences.

Despite the high tobacco use rates (~80%) and tobacco-related cancers being the second leading cause of death among people experiencing homelessness within the United States, these individuals rarely receive tobacco use treatment from homeless-serving agencies (HSAs). This qualitative study explored the enablers and inhibitors of implementing an evidence-based tobacco-free workplace (TFW) program offering TFW policy adoption, specialized provider training to treat tobacco use, and nicotine replacement therapy (NRT) within HSAs. Pre- and post-implementation interviews with providers and managers (n = 13) pursued adapting interventions to specific HSAs and assessed the program success, respectively. The organizational readiness for change theory framed the data content analysis, yielding three categories: change commitment, change efficacy and contextual factors. Pre- to post-implementation, increasing challenges impacted the organizational capacity and providers' attitudes, wherein previously enabling factors were reframed as inhibiting, resulting in limited implementation despite resource provision. These findings indicate that low-resourced HSAs require additional support and guidance to overcome infrastructure challenges and build the capacity needed to implement a TFW program. This study's findings can guide future TFW program interventions, enable identification of agencies that are well-positioned to adopt such programs, and facilitate capacity-building efforts to ensure their successful participation.
