Design, implementation, and evaluation of community health worker training programs in Latinx communities: A scoping review.

This review examines the current reporting trends of program design, implementation, and evaluation of training programs for Latinx community health workers. Five scholarly databases were searched using a scoping review methodology to identify articles describing training programs for Latinx community health workers. The timeframe was 2009 to 2021. We identified 273 articles, with 59 meeting inclusion criteria. Researchers thematically coded the articles to identify reporting strategies related to program design, implementation, and evaluation. Findings suggest a lack of consensus in reporting elements critical to program resources, instructor qualifications, frequency and length of training implementation, theoretical background, and pedagogical tools associated with the training program. We offer detailed reporting recommendations of community health worker training programs to support the consistent dissemination of promising practices and facilitate the initiation of new programs for Latinx community health workers.

Promotoras Voice Their Challenges in Fulfilling Their Role as Community Health Workers.

Promotoras de salud (Spanish for female community health workers) are integral to efforts to enhance the health and well-being of Latinx individuals, families, and communities. The purpose of this study was to describe the challenges that promotoras face and the proposed solutions from the perspective of the promotoras themselves. Five promotoras who worked for a year as volunteers in a community-based participatory research study, Lazos Hispanos, participated in two group interviews. Eight challenges emerged-balancing their new work with their family commitments, handling their perceived imbalance of power with men, managing the emotional impact of hearing participants' problems, facing and handling the barriers imposed by having limited English language skills, feeling discouraged by the perception of ethnocentric beliefs and discrimination from some providers, feeling disheartened by the cultural beliefs of some Latinx participants, handling the lack of transportation for themselves and for the participants, and managing the burden of data collection for the research aspect of the program. The explanation of these challenges and the practical solutions they proposed are embedded in their intersecting identities. The solutions are a valuable addition to the practice of health promotion and community-based participatory research, particularly within Latinx communities.

Lazos Hispanos: Promising Strategies and Lessons Learned in the Development of a Multisystem, Community-Based Promotoras Program.

U.S. Latinos face multiple inter-related barriers to access health and social services. Researchers and practitioners have called upon community-based participatory research (CBPR) to address such challenges and health disparities, with the community health worker-or promotoras-model evidencing positive outcomes. What is less clear, however, are the promising strategies to support the development of a multisystem, community-based promotoras program. In response, the current study applied a CBPR conceptual model as an organizing framework to develop a promotora program. Lazos Hispanos (Hispanic Links) was developed to enhance the health and well-being of Latinx residing in low-income communities in the Southeastern United States. This study highlights 16 lessons learned, anchored in the first two dimensions of the CBPR conceptual model: community context and partnership development. First, the community assessment and activities leading to Lazos Hispanos took nearly 2 years but were crucial to develop a strong basis for the program. Second, the development of a multicultural and interdisciplinary research team enriched every aspect of the program and enhanced culturally responsive community engagement. Selection, training, and ongoing support of the promotoras were fundamental to program success. Particularly important were the following: receiving mentorship from a successful promotora organization; delineating mutually agreed upon roles and responsibilities; following national training standards for community health workers; and, holding monthly meetings for training, support, and data collection. The engagement of community service providers as partners was facilitated by building upon existing community relationships, signing a memorandum of understanding that specified roles and responsibilities, conducting tours of provider facilities with the promotoras, and keeping providers abreast of the program via bi-annual community gatherings. The development process showed fidelity to the conceptual model. Lazos Hispanos has proven an asset to participants, the promotoras, and service providers as the program continues to develop a community-based, health supportive infrastructure.

Age and sex as confounding factors in the relationship between cardiac mitochondrial function and type 2 diabetes in the Nile Grass rat.

Our study revisits the role of cardiac mitochondrial adjustments during the progression of type 2 diabetes mellitus (T2DM), while considering age and sex as potential confounding factors. We used the Nile Grass rats (NRs) as the animal model. After weaning, animals were fed either a Standard Rodent Chow Diet (SRCD group) or a Mazuri Chinchilla Diet (MCD group) consisting of high-fiber and low-fat content. Both males and females in the SRCD group, exhibited increased body mass, body mass index, and plasma insulin compared to the MCD group animals. However, the females were able to preserve their fasting blood glucose throughout the age range on both diets, while the males showed significant hyperglycemia starting at 6 months in the SRCD group. In the males, a higher citrate synthase activity-a marker of mitochondrial content-was measured at 2 months in the SRCD compared to the MCD group, and this was followed by a decline with age in the SRCD group only. In contrast, females preserved their mitochondrial content throughout the age range. In the males exclusively, the complex IV capacity expressed independently of mitochondrial content varied with age in a diet-specific pattern; the capacity was elevated at 2 months in the SRCD group, and at 6 months in the MCD group. In addition, females, but not males, were able to adjust their capacity to oxidize long-chain fatty acid in accordance with the fat content of the diet. Our results show clear sexual dimorphism in the variation of mitochondrial content and oxidative phosphorylation capacity with diet and age. The SRCD not only leads to T2DM but also exacerbates age-related cardiac mitochondrial defects. These observations, specific to male NRs, might reflect deleterious dietary-induced changes on their metabolism making them more prone to the cardiovascular consequences of aging and T2DM.

A multistakeholder evaluation of Lazos Hispanos: An application of a community-based participatory research conceptual model.

The goal of Lazos Hispanos is to enhance the health and well-being of the Latinx community through promotoras, who connect community members with service providers for multiple health and social needs. A community-based participatory research conceptual model framed the multimethod evaluation of promotoras, service providers, and community participants at baseline and at the 1-year follow up. The promotoras increased their self-efficacy and knowledge, felt a strong sense of commitment to the community, viewed themselves as a bridge between participants and providers, and felt empowered by their new role. Service providers valued the promotoras as their ambassadors in the community and Lazos Hispanos as central to connecting service providers, promotoras, and community members; they noted that this collaboration increased their accountability with the Latinx community. This multistakeholder evaluation highlights the depth of positive changes achieved during the first year and the challenges of a community-embedded project and the benefits and possibilities of calling upon theoretically informed evaluation models.

Overcoming Barriers: Practical Strategies to Assess Latinos Living in Low-Income Communities.

The value of community assessments depends on the researchers' ability to reach a diverse and representative sample of participants. This process is particularly challenging when assessing the health and well-being of vulnerable populations that are reticent to participate in research because of demographic and sociopolitical factors. One such group is Latinxs (the gender-neutral version of Latinos or Latinas) of mixed immigration status who live in low-income, socially and geographically isolated enclaves in the Southeast. Framed by community-based participatory research and social marketing theories, this study describes practical strategies for health researchers, practitioners, and advocates seeking to engage and build trusting relationship within U.S. Latinx communities. First, identify and leverage points of entry to different segments of the communities of interest by engaging meaningful gatekeepers from different sections of the population and searching for places where potential participants gather. Second, reduce the burden of assessments by using incentives and creating intentional reciprocity. Third, establish critical, long-lasting trust with community members, leaders, and allies by adapting data collection procedures, ensuring confidentiality, engaging bilingual facilitators, and most important, being present with and for the community. Finally, presenting the findings back to the community can increase the ownership of the process.

Adjustments in the control of mitochondrial respiratory capacity to tolerate temperature fluctuations.

As the world's climate changes, life faces an evolving thermal environment. Mitochondrial oxidative phosphorylation (OXPHOS) is critical to ensure sufficient cellular energy production, and it is strongly influenced by temperature. The thermally induced changes to the regulation of specific steps within the OXPHOS process are poorly understood. In our study, we used the eurythermal species of planarian Dugesia tigrina to study the thermal sensitivity of the OXPHOS process at 10, 15, 20, 25 and 30°C. We conducted cold acclimation experiments where we measured the adjustment of specific steps in OXPHOS at two assay temperatures (10 and 20°C) following 4 weeks of acclimation under normal (22°C) or low (5°C) temperature conditions. At the low temperature, the contribution of the NADH pathway to the maximal OXPHOS capacity, in a combined pathway (NADH and succinate), was reduced. There was partial compensation by an increased contribution of the succinate pathway. As the temperature decreased, OXPHOS became more limited by the capacity of the phosphorylation system. Acclimation to the low temperature resulted in positive adjustments of the NADH pathway capacity due, at least in part, to an increase in complex I activity. The acclimation also resulted in a better match between OXPHOS and phosphorylation system capacities. Both of these adjustments following acclimation were specific to the low assay temperature. We conclude that there is substantial plasticity in the mitochondrial OXPHOS process following thermal acclimation in D. tigrina, and this probably contributes to the wide thermal range of the species.

Inferring genome-wide patterns of admixture in Qataris using fifty-five ancestral populations.

BACKGROUND: Populations of the Arabian Peninsula have a complex genetic structure that reflects waves of migrations including the earliest human migrations from Africa and eastern Asia, migrations along ancient civilization trading routes and colonization history of recent centuries. RESULTS: Here, we present a study of genome-wide admixture in this region, using 156 genotyped individuals from Qatar, a country located at the crossroads of these migration patterns. Since haplotypes of these individuals could have originated from many different populations across the world, we have developed a machine learning method "SupportMix" to infer loci-specific genomic ancestry when simultaneously analyzing many possible ancestral populations. Simulations show that SupportMix is not only more accurate than other popular admixture discovery tools but is the first admixture inference method that can efficiently scale for simultaneous analysis of 50-100 putative ancestral populations while being independent of prior demographic information. CONCLUSIONS: By simultaneously using the 55 world populations from the Human Genome Diversity Panel, SupportMix was able to extract the fine-scale ancestry of the Qatar population, providing many new observations concerning the ancestry of the region. For example, as well as recapitulating the three major sub-populations in Qatar, composed of mainly Arabic, Persian, and African ancestry, SupportMix additionally identifies the specific ancestry of the Persian group to populations sampled in Greater Persia rather than from China and the ancestry of the African group to sub-Saharan origin and not Southern African Bantu origin as previously thought.

Adherence, body mass index, and depression in adults with type 2 diabetes: the mediational role of diabetes symptoms and self-efficacy.

OBJECTIVE: Evidence indicates that depression is linked to the development and worsening of diabetes, but the mechanisms underlying this link are not well understood. The authors examined the hypothesis that diabetes-related symptoms mediate the effect of both behavioral adherence and body mass index (BMI) on depression. In addition, they examined whether a prior finding that self-efficacy mediates the effect of behavioral adherence and BMI on depression would replicate with a larger sample size (W. P. Sacco, K. J. Wells, C. A. Vaughan, A. Friedman, S. Perez, & R. Morales, 2005). Also, the relative contributions of diabetes-related symptoms and self-efficacy to depression were evaluated. DESIGN AND PARTICIPANTS: Cross-sectional design involving adults diagnosed with Type 2 diabetes (N = 99). MAIN OUTCOME MEASURES: The primary outcome measure was depression (Patient Health Questionnaire: Nine Symptom Depression Checklist). Predictors of depression were diet and exercise adherence (Summary of Diabetes Self-Care Activities Questionnaire), diet and exercise self-efficacy (Multidimensional Diabetes Questionnaire), diabetes symptoms (Diabetes Symptom Checklist), and BMI (based on height and weight data from medical records). RESULTS: Path and mediation analyses indicated that adherence and BMI each contributed to depression indirectly, via their effects on self-efficacy and diabetes-related medical symptoms. CONCLUSION: Results provide evidence consistent with two independent pathways by which BMI and adherence could increase depression in people with Type 2 diabetes. The first pathway indicates that the effects of higher BMI and poor adherence on depression are mediated by lower self-efficacy perceptions. The second pathway indicates that the effect of higher BMI on depression is mediated by increased diabetes symptoms.

Methods used to streamline the CAHPS Hospital Survey.

OBJECTIVE: To identify a parsimonious subset of reliable, valid, and consumer-salient items from 33 questions asking for patient reports about hospital care quality. DATA SOURCE: CAHPS Hospital Survey pilot data were collected during the summer of 2003 using mail and telephone from 19,720 patients who had been treated in 132 hospitals in three states and discharged from November 2002 to January 2003. METHODS: Standard psychometric methods were used to assess the reliability (internal consistency reliability and hospital-level reliability) and construct validity (exploratory and confirmatory factor analyses, strength of relationship to overall rating of hospital) of the 33 report items. The best subset of items from among the 33 was selected based on their statistical properties in conjunction with the importance assigned to each item by participants in 14 focus groups. PRINCIPAL FINDINGS: Confirmatory factor analysis (CFA) indicated that a subset of 16 questions proposed to measure seven aspects of hospital care (communication with nurses, communication with doctors, responsiveness to patient needs, physical environment, pain control, communication about medication, and discharge information) demonstrated excellent fit to the data. Scales in each of these areas had acceptable levels of reliability to discriminate among hospitals and internal consistency reliability estimates comparable with previously developed CAHPS instruments. CONCLUSION: Although half the length of the original, the shorter CAHPS hospital survey demonstrates promising measurement properties, identifies variations in care among hospitals, and deals with aspects of the hospital stay that are important to patients' evaluations of care quality.

Depression in adults with type 2 diabetes: the role of adherence, body mass index, and self-efficacy.

Considerable evidence links depression with the development and worsening of diabetes, but the factors contributing to this link have not been established. The authors examined the role of adherence, body mass index (BMI), and self-efficacy. Adult patients with Type 2 diabetes (N = 56) completed self-report measures of diet and exercise adherence, diet and exercise self-efficacy, and depression. BMI was obtained from medical records. Path and mediation analyses indicated that both adherence and BMI independently contributed to self-efficacy. Self-efficacy mediated both the association between adherence and depression and the association between BMI and depression. These findings are consistent with the proposal that lower self-efficacy in reaction to adherence failure and higher BMI contributes to depression in adults with diabetes.
