El Nacimiento del Pueblo Mestizo: Critical Discourse on Historical Trauma, Community Resilience and Healing.

Purpose. Historical trauma has been widely applied to American Indian/Alaska Native and other Indigenous populations and includes dimensions of language, sociocultural, and land losses and associated physical and mental disorders, as well as economic hardships. Insufficient evidence remains on the experiences of historical trauma due to waves of colonization for mixed-race Mexican people with indigenous ancestry (el pueblo mestizo). Research Question. Drawing from our critical lenses and epistemic advantages as indigenous feminist scholars, we ask, "How can historical trauma be understood through present-day discourse of two mestizo communities? What are public health practice and policy implications for healing historical trauma among mestizo populations?" Methodology and Approach. We analyzed the discourse from two community projects: focus groups and ethnographic field notes from a study in the U.S.-Mexico border region (2012-2014) and field notes and digital stories from a service-learning course in northern New Mexico (2016-2018). Findings. Our analysis describes the social and historical experiences of Mexicans, Mexican Americans, Chicanas/os, and Nuevo Mexicano peoples in the southwestern border region of the United States. We found four salient themes as manifestations of "soul-wound": (1) violence/fear, (2) discrimination/shame, (3) loss, and (4) deep sorrow. Themes mitigating the trauma were community resiliency rooted in "querencia" (deep connection to land/home/people) and "conscientizacion" (critical consciousness). Conclusion. Historical trauma experienced by mestizo Latinx communities is rooted in local cultural and intergenerational narratives that link traumatic events in the historic past to contemporary local experiences. Future public health interventions should draw on culturally centered strength-based resilience approaches for healing trauma and advancing health equity.

Power Dynamics in Community-Based Participatory Research: A Multiple-Case Study Analysis of Partnering Contexts, Histories, and Practices.

Community-based participatory research has a long-term commitment to principles of equity and justice with decades of research showcasing the added value of power-sharing and participatory involvement of community members for achieving health, community capacity, policy, and social justice outcomes. Missing, however, has been a clear articulation of how power operates within partnership practices and the impact of these practices on outcomes. The National Institutes of Health-funded Research for Improved Health study (2009-2013), having surveyed 200 partnerships, then conducted seven in-depth case studies to better understand which partnership practices can best build from community histories of organizing to address inequities. The diverse case studies represented multiple ethnic-racial and other marginalized populations, health issues, and urban and rural areas and regions. Cross-cutting analyses of the qualitative results focus on how oppressive and emancipatory forms of power operate within partnerships in response to oppressive conditions or emancipatory histories of advocacy within communities. The analysis of power was conducted within each of the four domains of the community-based participatory research conceptual model, starting from how contexts shape partnering processes to impact short-term intervention and research outputs, and contribute to outcomes. Similarities and differences in how partnerships leveraged and addressed their unique contexts and histories are presented, with both structural and relational practices that intentionally addressed power relations. These results demonstrate how community members draw from their resilience and strengths to combat histories of injustice and oppression, using partnership principles and practices toward multilevel outcomes that honor community knowledge and leadership, and seek shared power, policy, and community transformation changes, thereby advancing health equity.

Glucose and cholesterol stabilization in patients with type 2 diabetes mellitus with depressive and anxiety symptoms by problem-solving therapy in primary care centers in Mexico City.

Aim The aim of this study was to determine if the problem-solving therapy (PST) helps control metabolic variables in patients with type 2 diabetes mellitus (T2DM) who show depressive and anxiety symptoms. BACKGROUND: T2DM is a chronic-degenerative multifactorial disease. It is considered one of the main public health problems in the world, and it represents an important social and economic burden. It is frequently associated with major depression and anxiety disorders, which are related with high glycated hemoglobin (HbA1c) concentrations and poor metabolic control. METHOD: We initially included 123 patients diagnosed with T2DM from five primary care centers (PCC) in Mexico City. HbA1c, central glucose, and lipid profile were measured in each patient. In addition, the Kessler psychological distress scale (K-10), the Beck Depression Inventory, and the Beck Anxiety Inventory were applied at the beginning and, to those who continued, at the end of the PST, as well as four months later. Findings In total, 36 patients completed the PST and the follow-up. There was a significant decrease in depressive and anxiety symptoms (P<0.001), as well as in total cholesterol (P=0.002), HbA1c (P=0.05), and low-density lipoprotein (LDL) (P=0.022). The PST helps reduce depressive and anxiety symptoms and may help stabilize glucose and cholesterol up to four months. Further studies on this area are recommended. If our findings are confirmed, the PST could help improve the quality of life of thousands of individuals with psychiatric-metabolic co-morbidity who only visit PCC.

Culturally sensitive assessments as a strength-based approach to wellness in Native communities: A community-based participatory research project.

American Indians and Alaska Natives (AI/ANs) have a unique, traumatic, and alienating history of education in the U.S., which may be directly related to overall health and well-being. Community engagement is critical in well-being research with Native communities, especially when investigating culturally sensitive topics, such as early education experiences. This study investigates the value of a community-based participatory research approach in gaining valuable culturally sensitive information from Native people in a respectful manner. Assessment participation and feedback are analyzed and presented as indicators of Native participant engagement success in a potentially sensitive research project exploring early education experiences.

Factors of interpersonal communication and behavioral health on medication self-efficacy and medication adherence.

Despite devastating effects on health outcomes and disease progression, many people living with HIV (PLWH) are non-adherent to their medications. Medication self-efficacy is a pivotal factor in medication adherence, yet its formation and relationship with other factors are understudied. This study examines a model that considers the role of three communicative factors (patient-provider communication, social support, and social undermining) and two behavioral health factors (depression and alcohol abuse) and medication self-efficacy impacting medication adherence. Methods included a cross-sectional design using a survey questionnaire of 344 PLWH. Findings indicated that 25% of variance in medication adherence can be explained by a mediation model where depression (B = -.18) and provider-patient communication (B = .21) affect medication self-efficacy, which in turn impacts medication adherence (B = .64). Other variables, including demographics, did not add any explanatory power. These findings demonstrate the complex nature of medication adherence and the formation of medication self-efficacy.

Patient-provider interaction, patient satisfaction, and health outcomes: testing explanatory models for people living with HIV/AIDS.

In the era of highly active antiretroviral therapy era, medication adherence and health-related quality of life (HRQOL) have become critical issues for people living with HIV/AIDS (PLWH). The purpose of this study was to test explanatory models of how patient-provider interaction and patient satisfaction are related to medication adherence and HRQOL for PLWH. A total of 344 PLWH receiving health-care services from a federally funded clinic in the southwest USA completed a survey questionnaire about their perception of interactions with providers, their satisfaction with services, their medication adherence, and their HRQOL. Comparing four latent variable structural equation models of direct and mediated effects of patient-provider interaction and patient satisfaction, the findings illustrate that the best model is one in which patient-provider interaction has a direct and positive effect on patient satisfaction, medication adherence, and HRQOL. These findings suggest that quality patient-provider interaction is a critical element of health-care services for PLWH, while patient satisfaction is an outcome measure and not a mediating factor for medication adherence and HRQOL.

Reflections on Researcher Identity and Power: The Impact of Positionality on Community Based Participatory Research (CBPR) Processes and Outcomes.

The practice of community based participatory research (CBPR) has evolved over the past 20 years with the recognition that health equity is best achieved when academic researchers form collaborative partnerships with communities. This article theorizes the possibility that core principles of CBPR cannot be realistically applied unless unequal power relations are identified and addressed. It provides theoretical and empirical perspectives for understanding power, privilege, researcher identity and academic research team composition, and their effects on partnering processes and health disparity outcomes. The team's processes of conducting seven case studies of diverse partnerships in a national cross-site CBPR study are analyzed; the multi-disciplinary research team's self-reflections on identity and positionality are analyzed, privileging its combined racial, ethnic, and gendered life experiences, and integrating feminist and post-colonial theory into these reflections. Findings from the inquiry are shared, and incorporating academic researcher team identity is recommended as a core component of equalizing power distribution within CBPR.

HIV health-care providers' burnout: can organizational culture make a difference?

One of the major challenges facing those working with people living with HIV (PLWH) is the increased potential for burnout, which results in increased turnover and reduces quality of care provided for PLWH. The goal of this study was to examine the relationship among HIV health-care providers' burnout (emotional exhaustion and depersonalization) and organizational culture including teamwork, involvement in decision-making, and critical appraisal. Health-care providers for PLWH (N = 47) in federally funded clinics in a southwestern state completed a cross-sectional survey questionnaire about their perceptions of organizational culture and burnout. The results of multiple regression analysis indicated that positive organizational culture (i.e., teamwork) was negatively related to emotional burnout (p < .005, R(2) = .18). Further negative organizational culture (i.e., critical appraisal) was positively related to depersonalization (p < .005, R(2) = .18). These findings suggest that effective organizational communication interventions might protect HIV health-care providers from burnout.

Social support and social undermining as explanatory factors for health-related quality of life in people living with HIV/AIDS.

This study aimed to examine the influence of social support (from personal networks and health care providers) and social undermining (from personal networks) on health-related quality of life (HRQOL; general health perceptions, physical functioning, and depression). Specifically, the authors aimed to identify the nature of the effects (direct, mediating, or moderating) of social support and social undermining on HRQOL. A total of 344 people living with HIV/AIDS and who were patients in a federally funded clinic in New Mexico completed a self-report survey questionnaire. The major findings of this study are the following: (a) social support and social undermining had direct and indirect effects on HRQOL-there was no evidence of a moderating effect of social support and social undermining; (b) for direct effects, social undermining was a stronger predictor of HRQOL than social support with social support variables having positive relations and social undermining variables having negative relations with HRQOL; and (c) for indirect effects, providers' social support partially mediated the influence of unstable employment/unemployment and social undermining on HRQOL.

Eficacia de la espectrometría de masas MALDI-TOF en la identificación de bacterias anaerobias / No disponible

Objetivo. La espectrometría de masas (EM) MALDI-TOF se ha convertido en un recurso de referencia para la identificación de microorganismos en los servicios de microbiología clínica. No obstante, los datos relativos a algunos grupos de microorganismos son todavía controvertidos. En el presente estudio se ha determinado la fiabilidad de la EM MALDI-TOF para la identificación de aislamientos clínicos de bacterias anaerobias, en comparación con técnicas bioquímicas convencionales, y usando como referencia en caso de discrepancias las secuenciación de ARNr 16S.Material y métodos Se analizaron 126 aislamientos clínicos de bacterias anaerobias mediante el sistema API 20A (bioMérieux, Marcy l’Étoile, Francia) y mediante EM MALDI-TOF (Autoflex II, Bruker Daltonics, Alemania), utilizando la base de datos BioTyper 2.0 (Bruker Daltonics, Alemania). Cuando se produjeron discrepancias, o la EM MALDI-TOF no fue capaz de identificar microorganismo alguno, se usó como método de identificación de referencia la secuenciación del ARNr 16S.ResultadosEl método bioquímico y la EM MALDI-TOF coincidieron, a nivel de especie, en el 60,9% de los casos, y solo a nivel de género en el 20,3%. De las 48 identificaciones discrepantes, la secuenciación respaldó la identificación por EM MALDI-TOF a nivel de especie en 32 casos (66,7%), y a nivel de género en 8 (16,7%). Dicha secuenciación apoyó la identificación bioquímica a nivel de especie solamente en 2 casos (..) (AU)

Evaluating community-based participatory research to improve community-partnered science and community health.

BACKGROUND: Since 2007, the National Congress of American Indians (NCAI) Policy Research Center (PRC) has partnered with the Universities of New Mexico and Washington to study the science of community-based participatory research (CBPR). Our goal is to identify facilitators and barriers to effective community-academic partnerships in American Indian and other communities, which face health disparities. OBJECTIVES: We have described herein the scientific design of our National Institutes of Health (NIH)-funded study (2009-2013) and lessons learned by having a strong community partner leading the research efforts. METHODS: The research team is implementing a mixed-methods study involving a survey of principal investigators (PIs) and partners across the nation and in-depth case studies of CBPR projects. RESULTS: We present preliminary findings on methods and measures for community-engaged research and eight lessons learned thus far regarding partnership evaluation, advisory councils, historical trust, research capacity development of community partner, advocacy, honoring each other, messaging, and funding. CONCLUSIONS: Study methodologies and lessons learned can help community-academic research partnerships translate research in communities.

[Reliability of MALDI-TOF mass spectrometry in the identification of anaerobic bacteria]. / Eficacia de la espectrometría de masas MALDI-TOF en la identificación de bacterias anaerobias.

AIM OF THE STUDY: MALDI-TOF mass spectrometry (MS) is becoming a major resource in the Clinical Microbiology laboratory. Results on some groups of microorganisms are still controversial. We have studied the reliability of MALDI-TOF MS for the identification of anaerobic clinical isolates was studied compared to conventional biochemical methods, with rRNA 16S sequencing being used as a reference when discrepancies arose. MATERIAL AND METHODS: A total of 126 anaerobic bacteria clinical isolates were studied by using API20A kits (bioMérieux, Marcy l'Étoile, France) and MALDI-TOF MS (Autoflex II, Bruker Daltonics, Germany), and using the data library BioTyper 2.0 (Bruker Daltonics, Germany). When discrepancies arose, or MALDI-TOF MS was not able to identify any microorganism, rRNA 16S sequencing was used as the reference standard. RESULTS: The biochemical method and MALDI-TOF MS agreed in identifying 60.9% of isolates at species level, and 20.3% of isolates at genus level. Among the 48 discrepancies observed, rRNA 16S sequencing supported MALDI-TOF MS identification, at species level, in 32 isolates (66.7%), and in 8 isolates (16.7%) at genus level. rRNA 16S sequencing supported biochemical identification in only two isolates (4.2%) at species level, and in 26 isolates (54.2%) at genus level. The eight isolates for which MALDI-TOF MS did not manage to identify, or the identification obtained was rejected by sequencing, belonged to species that are still not added to the BioTyper II data library. CONCLUSIONS: Results obtained in this study show that, overall, MALDI-TOF MS identification of anaerobic bacteria is more reliable than identification obtained by conventional biochemical methods (24% more correct identifications at species level). The number of major errors (incorrect identification at the genus level) is also 2.5-times lower. Moreover, all the major errors obtained by MALDI-TOF MS were due to the absence of some species in the data library. Thus, when data libraries are more complete, reliability differences between both methods will probably be even higher.

Rethinking Research Ethics for Latinos: The Policy Paradox of Health Reform and the Role of Social Justice.

This article discusses the paradox of exclusion/inclusion: U.S. health policy prohibits Latinos who fall under certain classifications from accessing health services and insurance yet permits them to be "human subjects" in health research. We aim to advance the discussion of health research ethics post the Tuskegee syphilis experiment in Latinos by (a) tracing the impacts of policy exclusion and the social context of anti-Latino sentiment on Latinos' low participation rates in health research and inequitable access to treatment modalities; (b) challenging researchers to address social sources of vulnerabilities; and (c) offering recommendations on adapting a social justice ethical stance to address these challenges, which are part of the Tuskegee Study legacy.

Process and outcome constructs for evaluating community-based participatory research projects: a matrix of existing measures.

Community-based participatory research (CBPR) has been widely used in public health research in the last decade as an approach to develop culturally centered interventions and collaborative research processes in which communities are directly involved in the construction and implementation of these interventions and in other application of findings. Little is known, however, about CBPR pathways of change and how these academic-community collaborations may contribute to successful outcomes. A new health CBPR conceptual model (Wallerstein N, Oetzel JG, Duran B et al. CBPR: What predicts outcomes? In: Minkler M, Wallerstein N (eds). Communication Based Participatory Research, 2nd edn. San Francisco, CA: John Wiley & Co., 2008) suggests that relationships between four components: context, group dynamics, the extent of community-centeredness in intervention and/or research design and the impact of these participatory processes on CBPR system change and health outcomes. This article seeks to identify instruments and measures in a comprehensive literature review that relates to these distinct components of the CBPR model and to present them in an organized and indexed format for researcher use. Specifically, 258 articles were identified in a review of CBPR (and related) literature from 2002 to 2008. Based on this review and from recommendations of a national advisory board, 46 CBPR instruments were identified and each was reviewed and coded using the CBPR logic model. The 46 instruments yielded 224 individual measures of characteristics in the CBPR model. While this study does not investigate the quality of the instruments, it does provide information about reliability and validity for specific measures. Group dynamics proved to have the largest number of identified measures, while context and CBPR system and health outcomes had the least. Consistent with other summaries of instruments, such as Granner and Sharpe's inventory (Granner ML, Sharpe PA. Evaluating community coalition characteristics and functioning: a summary of measurement tools. Health Educ Res 2004; 19: 514-32), validity and reliability information were often lacking, and one or both were only available for 65 of the 224 measures. This summary of measures provides a place to start for new and continuing partnerships seeking to evaluate their progress.

Direct identification of urinary tract pathogens from urine samples by matrix-assisted laser desorption ionization-time of flight mass spectrometry.

Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has been suggested as a reliable method for bacterial identification from cultures. Direct analysis of clinical samples might increase the usefulness of this method, shortening the time for microorganism identification. We compared conventional methods for the diagnosis of urinary tract infections (UTIs) and identification of the urinary tract pathogens (automated screening, plate cultures, and identification based on biochemical characteristics) and a fast method based on conventional screening and MALDI-TOF MS. For this latter method, 4 ml of urine was centrifuged at a low-revolution setting (2,000 x g) to remove leukocytes and then at high revolutions (15,500 x g) to collect bacteria. The pellet was washed and then applied directly to the MALDI-TOF MS plate. Two hundred sixty urine samples, detected as positive by the screening device (UF-1000i), were processed by culture and MALDI-TOF MS. Twenty samples were positive in the screening device but negative in culture, and all of them were also negative by MALDI-TOF MS. Two-hundred thirty-five samples displayed significant growth of a single morphological type in culture. Two-hundred twenty of them showed bacterial growth of >10(5) CFU/ml. Microorganism identifications in this group were coincident at the species level in 202 cases (91.8%) and at the genus level in 204 cases (92.7%). The most frequent microorganism was Escherichia coli (173 isolates). MALDI-TOF MS identified this microorganism directly from the urine sample in 163 cases (94.2%). Our results show that MALDI-TOF MS allows bacterial identification directly from infected urine in a short time, with high accuracy, and especially when Gram-negative bacteria with high bacterial counts are involved.
