Replacement of core team members on embedded implementation research teams: experiences from Latin America and the Caribbean.

Objective: To understand how replacement of decision-makers (DMs) serving as principal investigators (PI) or co-PIs on research teams may affect the feasibility and value of embedded implementation research (EIR) used to improve health policies, programs, and services in Latin America and the Caribbean. Methods: This was a descriptive qualitative study based on 39 semistructured interviews with 13 embedded research teams selected by financing agencies to explore team composition, interaction among members, and research results. Interviews were conducted at three points during the study period from September 2018 to November 2019; data were analyzed from 2020 to 2021. Results: Research teams were found to be operating in one of three situations: (i) permanent core team (no change) with either active DM or inactive DM participation; (ii) replacement of DM-PI or co-PI that did not affect EIR research; and (iii) replacement of DM-PI that affected EIR. Conclusions: To ensure EIR continuity and stability, research teams should include high-level DMs together with more technical staff performing essential implementation activities. This structure could improve collaboration among professional researchers and ensure greater embeddedness of EIR to strengthen the health system.

[RESUMEN]. Objetivo. Comprender de qué manera la sustitución de los responsables de tomar decisiones (RTD) que se desempeñan como investigadores principales (IP) o coinvestigadores principales (coIP) en los equipos de investigación puede incidir en la viabilidad y el valor de la investigación integrada en materia de ejecución (IIME) utilizada con el objetivo de mejorar las políticas, los programas y los servicios de salud en América Latina y el Caribe. Métodos. Este estudio cualitativo descriptivo se basó en 39 entrevistas semiestructuradas realizadas a 13 equipos de investigación integrada seleccionados por organismos de financiación con el objetivo de estudiar la composición de los equipos, la interacción entre sus miembros y los resultados de la investigación. Las entrevistas se realizaron en tres ocasiones durante el período de estudio, que se extendió de septiembre del 2018 a noviembre del 2019; los datos se analizaron entre el 2020 y el 2021. Resultados. Se encontró que los equipos de investigación se desempeñaban en una de las siguientes tres situaciones: a) un equipo central permanente (sin cambios), sea con participación activa del RTD o sin par- ticipación activa del mismo; b) sustitución del RTD–IP o coIP, sin consecuencias para la IIME; y c) sustitución del RTD–IP, con consecuencias para la IIME. Conclusiones. Para asegurar la continuidad y estabilidad de la IIME, los equipos de investigación deberían incluir RTD de alto nivel junto con más personal técnico que lleve a cabo actividades esenciales en materia de ejecución. Esta estructura podría mejorar la colaboración entre los investigadores profesionales y asegurar una mayor integración de la IIME con la finalidad de fortalecer el sistema de salud.

[RESUMO]. Objetivo. Mapear políticas relacionadas à prevenção e ao controle da resistência aos antimicrobianos na perspectiva da saúde humana no Brasil e sistematizar a evolução histórica dessas políticas. Método. Desenvolveu-se uma revisão de escopo conforme as diretrizes do Instituto Joana Briggs e PRISMA. A busca na literatura foi realizada em dezembro de 2020 nas bases de dados LILACS, PubMed e EMBASE. Utilizaram-se os termos “antimicrobial resistance” AND “Brazil” e sinônimos. Uma pesquisa documental com os mesmos termos foi conduzida nos sites eletrônicos do governo brasileiro até dezembro de 2021. Foram incluídos estudos de todos os desenhos, sem restrição de idioma ou data. Excluíram-se documentos clínicos, revisões e estudos epidemiológicos que não referenciavam políticas de gestão da resistência aos antimicrobianos no Brasil. Para coleta e análise de dados, estabeleceram-se categorias baseadas em documentos da Organização Mundial da Saúde. Resultados. Desde antes da criação do Sistema Único de Saúde, o Brasil possuía políticas relacionadas à resistência aos antimicrobianos, como o Programa Nacional de Imunização e programas de controle de infecção hospitalar. No final das décadas de 1990 e 2000, estabeleceram-se as primeiras políticas específicas sobre resistência aos antimicrobianos (redes e programas de vigilância) e estratégias de educação. Desta- ca-se o Plano de Ação Nacional de Prevenção e Controle da Resistência aos Antimicrobianos no Âmbito da Saúde Única (PAN-BR), de 2018. Conclusões. Apesar do longo histórico de políticas relacionadas à resistência aos antimicrobianos no Brasil, foram identificadas lacunas, sobretudo no monitoramento da utilização de antimicrobianos e na vigilância da resistência aos antimicrobianos. O PAN-BR, primeiro documento de governo elaborado na perspectiva One Health, é um marco nas políticas brasileiras.

RESUMO Objetivo. Entender como a substituição de decisores atuando como investigadores principais ou co-investigadores em equipes de pesquisa pode afetar a viabilidade e o valor da pesquisa de implementação incorporada (EIR, na sigla em inglês), método usado para aprimorar as políticas, programas e serviços de saúde na América Latina e no Caribe. Métodos. Estudo qualitativo e descritivo, baseado em 39 entrevistas semiestruturadas com 13 equipes de pesquisa incorporadas, selecionadas por agências de fomento, para explorar a composição das equipes, a interação entre os membros e os resultados das pesquisas. As entrevistas foram realizadas em três momentos durante o período de estudo, de setembro de 2018 a novembro de 2019. Os dados foram analisados de 2020 a 2021. Resultados. Verificou-se que as equipes de pesquisa se encontravam em uma das seguintes três situações: (i) equipe essencial permanente (sem alteração), com participação ativa ou inativa do decisor; (ii) substituição do decisor (investigador principal ou co-investigador) não afetou a pesquisa EIR; e (iii) substituição do decisor (investigador principal ou co-investigador) afetou a pesquisa EIR. Conclusões. Para garantir a continuidade e estabilidade de pesquisas de EIR, as equipes de pesquisa devem incluir decisores de alto nível, juntamente com pessoal de perfil mais técnico, para realizar atividades essenciais de implementação. Tal estrutura poderia melhorar a colaboração entre pesquisadores profissionais e garantir uma incorporação ainda maior da EIR para fortalecer o sistema de saúde.

Collaboration between health system decision makers and professional researchers to coproduce knowledge, a scoping review.

BACKGROUND: Recent literature uses different terms and approaches to the collaboration between researchers and health system decision-makers in the research process. In 2012, the World Health Organisation proposed to "Embed research within decision-making processes". Yet, important contributions use other terms and perspectives for the same issue. This scoping review aimed to identify these terms, approaches, their application and eventual influence on the utilization of evidence. METHODS: We searched papers published between January 2000 and February 2019 in English, Spanish, French and Portuguese in the databases of PubMed, Scielo, Google Scholar and EBSCOhost, thus accessing MedicLatina, MEDLINE Complete and eBook Collection. Our main inclusion criterion was the participation of health personnel in non-clinical research activities. We considered three domains for in depth analysis: Definition, name and description of the participation of decision makers and health staff; Forms of collaboration and actual/effective participation of health staff in research; Eventual influence on the utilization of research results. RESULTS: We identified 607 articles and selected 74 for full text analysis. Nineteen different terms are currently used in twelve countries to describe the participation of health decision-makers and staff in research activities. Most publications refer to Integrated Knowledge Translation or Embedded Research, and were published in Canada and the United Kingdom. Forty-five papers discuss the participation of health staff in research activities; 20 leading the whole process and 21 as collaborators. CONCLUSIONS: The identification of the different terms and approaches to the close collaboration of health staff and decision-makers with professional researchers is essential to promote its effective application and influence on the utilization of evidence. Yet, it is also necessary to insist in their co-participation throughout the whole investigation process as a relevant way to improve research results uptake, strengthen health systems and advance towards universal health coverage.

Care friendliness in adolescent sexual and reproductive health services in Mexico and a characterisation of their clients.

BACKGROUND: Sexual and reproductive health (SRH) is a very important issue in public health programs in low -and middle-income countries (LMICs). Health services that meet specific and differentiated needs of adolescents are increasingly relevant in LMICs. To provide quality services, it is necessary to know the profile of its users and the perspective that adolescents have about SRH services aimed at them. METHODS: We conducted a cross-sectional analysis of primary data from a survey of 489 adolescents recruited in 11 primary-care facilities in the state of Morelos, Mexico. We followed the guidelines outlined in the World Health Organization Quality Assessment Guidebook: A guide to assessing health services for adolescent clients. Data on friendliness of services were obtained through 70 questions divided into 18 characteristics which, in turn, were grouped into five domains: equity, accessibility, acceptability, appropriateness, and effectiveness. The "friendliness" (a proxy for quality of care) of services was measured according to an additive index of friendliness (FI) ranging from 0 (no friendliness) to 1 (maximum friendliness). We also described the socio-demographic, SRH, and service utilization profiles of clients. RESULTS: The health services analysed were characterised as having low levels of accessibility (FI = 0.62) and effectiveness (FI = 0.77), moderate acceptability (FI = 0.84), and high levels of appropriateness (FI = 0.93) and equity (FI = 0.92). Of the total number of adolescents surveyed, 51% stated that they had initiated a sexual life, 37% did not use any method of protection during their first sexual intercourse and 64% of the adolescents had already experienced a pregnancy. CONCLUSIONS: It is essential to improve the accessibility and effectiveness dimensions of adolescent-friendly services in Mexico. This requires the implementation of strategies specifically designed to promote well-informed, planned and healthy sexual behaviours that avert risk and vulnerability. Strategies need to consider the profile of the adolescent client population.

A Bayesian spatio-temporal analysis of mortality rates in Spain: application to the COVID-19 2020 outbreak.

BACKGROUND: The number of deaths attributable to COVID-19 in Spain has been highly controversial since it is problematic to tell apart deaths having COVID as the main cause from those provoked by the aggravation by the viral infection of other underlying health problems. In addition, overburdening of health system led to an increase in mortality due to the scarcity of adequate medical care, at the same time confinement measures could have contributed to the decrease in mortality from certain causes. Our aim is to compare the number of deaths observed in 2020 with the projection for the same period obtained from a sequence of previous years. Thus, this computed mortality excess could be considered as the real impact of the COVID-19 on the mortality rates. METHODS: The population was split into four age groups, namely: (< 50; 50-64; 65-74; 75 and over). For each one, a projection of the death numbers for the year 2020, based on the interval 2008-2020, was estimated using a Bayesian spatio-temporal model. In each one, spatial, sex, and year effects were included. In addition, a specific effect of the year 2020 was added ("outbreak"). Finally, the excess deaths in year 2020 were estimated as the count of observed deaths minus those projected. RESULTS: The projected death number for 2020 was 426,970 people, the actual count being 499,104; thus, the total excess of deaths was 72,134. However, this increase was very unequally distributed over the Spanish regions. CONCLUSION: Bayesian spatio-temporal models have proved to be a useful tool for estimating the impact of COVID-19 on mortality in Spain in 2020, making it possible to assess how the disease has affected different age groups accounting for effects of sex, spatial variation between regions and time trend over the last few years.

This article describes the main models for embedding research and the successful experiences and challenges faced in joint work by researchers and decisionmakers who participated in the Embedding Research for the Sustainable Development Goals (ER-SDG) initiative, and the experience of the Technical Support Center. In June 2018, funding was granted to 13 pre-selected research projects from 11 middle- and low-income countries in Latin America and the Caribbean (Argentina, Bolivia, Brazil, Colombia, Dominican Republic, Ecuador, Guatemala, Guyana, Haiti, Paraguay, and Peru). The projects focused on the system-, policy-, or program-level changes required to improve health and build on the joint work of researchers and decisionmakers, with a view to bringing together evidence production and decision-making in health systems and services. The Technical Support Center supported and guided the production of quality results useful for decision-making. This experience confirmed the value of initiatives such as ER-SDG in consolidating bridges between research on the implementation of health policies, programs, and systems, and the officials responsible for operating health-related programs, services, and interventions. It highlighted the importance of both respecting and taking advantage of each context-and the specific arrangements and patterns in the relationships between researchers and decisionmakers-through incentives for embedded research.

Neste artigo são descritos os principais modelos de integração, as experiências de êxito e os desafios do trabalho conjunto de pesquisadores e responsáveis por tomar decisões que participam da iniciativa Incorporação da Pesquisa para Avançar no Cumprimento dos Objetivos de Desenvolvimento Sustentável (Embedding Research for the Sustainable Development Goals, ER-SDG) e da experiência do Centro de Apoio Técnico (CAT). Em junho de 2018, realizou-se a concessão de financiamento e pré-seleção de 13 projetos de pesquisa provenientes de 11 países de baixa e média renda da América Latina e Caribe (Argentina, Bolívia, Brasil, Colômbia, Equador, Guatemala, Guiana, Haiti, Paraguai, Peru e República Dominicana). Os projetos deveriam enfocar as mudanças necessárias no sistema, políticas ou programas para melhorar a saúde e fundar-se no trabalho conjunto de pesquisadores e responsáveis por tomar decisões visando aproximar a produção de evidências à tomada de decisão nos sistemas e serviços de saúde. O CAT forneceu suporte e orientação à produção de resultados úteis e de qualidade para a tomada de decisão. A experiência confirmou o valor de iniciativas como a ER-SDG para consolidar pontes entre o mundo da pesquisa voltada à implementação de políticas, programas e sistemas de saúde e o mundo dos encarregados de gerir estes programas, serviços e intervenções de saúde. Deve-se enfatizar a necessidade de respeitar e aproveitar cada contexto e os arranjos e padrões próprios da relação entre pesquisadores e responsáveis por tomar decisões criando incentivos à integração.

ABSTRACT This article describes the main models for embedding research and the successful experiences and challenges faced in joint work by researchers and decisionmakers who participated in the Embedding Research for the Sustainable Development Goals (ER-SDG) initiative, and the experience of the Technical Support Center. In June 2018, funding was granted to 13 pre-selected research projects from 11 middle- and low-income countries in Latin America and the Caribbean (Argentina, Bolivia, Brazil, Colombia, Dominican Republic, Ecuador, Guatemala, Guyana, Haiti, Paraguay, and Peru). The projects focused on the system-, policy-, or program-level changes required to improve health and build on the joint work of researchers and decisionmakers, with a view to bringing together evidence production and decision-making in health systems and services. The Technical Support Center supported and guided the production of quality results useful for decision-making. This experience confirmed the value of initiatives such as ER-SDG in consolidating bridges between research on the implementation of health policies, programs, and systems, and the officials responsible for operating health-related programs, services, and interventions. It highlighted the importance of both respecting and taking advantage of each context—and the specific arrangements and patterns in the relationships between researchers and decisionmakers—through incentives for embedded research.

RESUMO Neste artigo são descritos os principais modelos de integração, as experiências de êxito e os desafios do trabalho conjunto de pesquisadores e responsáveis por tomar decisões que participam da iniciativa Incorporação da Pesquisa para Avançar no Cumprimento dos Objetivos de Desenvolvimento Sustentável (Embedding Research for the Sustainable Development Goals, ER-SDG) e da experiência do Centro de Apoio Técnico (CAT). Em junho de 2018, realizou-se a concessão de financiamento e pré-seleção de 13 projetos de pesquisa provenientes de 11 países de baixa e média renda da América Latina e Caribe (Argentina, Bolívia, Brasil, Colômbia, Equador, Guatemala, Guiana, Haiti, Paraguai, Peru e República Dominicana). Os projetos deveriam enfocar as mudanças necessárias no sistema, políticas ou programas para melhorar a saúde e fundar-se no trabalho conjunto de pesquisadores e responsáveis por tomar decisões visando aproximar a produção de evidências à tomada de decisão nos sistemas e serviços de saúde. O CAT forneceu suporte e orientação à produção de resultados úteis e de qualidade para a tomada de decisão. A experiência confirmou o valor de iniciativas como a ER-SDG para consolidar pontes entre o mundo da pesquisa voltada à implementação de políticas, programas e sistemas de saúde e o mundo dos encarregados de gerir estes programas, serviços e intervenções de saúde. Deve-se enfatizar a necessidade de respeitar e aproveitar cada contexto e os arranjos e padrões próprios da relação entre pesquisadores e responsáveis por tomar decisões criando incentivos à integração.

Well-being status and post-traumatic stress symptoms in health workers attending mindfulness sessions during the early stage of the COVID-19 epidemic in Mexico / Alteraciones en el bienestar y síntomas de estrés postraumático en trabajadores de la salud mexicanos que participaron en sesiones virtuales de atención plena durante la etapa inicial de la epidemia de COVID-19

Abstract Introduction In Mexico, a National Mental Health Strategy was implemented to identify and attend the mental health repercussions of the COVID-19 pandemic. It included the creation of five virtual clinics for health workers, being the Burnout, Post-traumatic Stress and Compassion Fatigue clinic one of them. Objective To describe the basal sociodemographic and psychological characteristics of health workers attending online mindfulness sessions as part of the treatment of the aforementioned clinic. Method This is a cross-sectional report part of a major nationwide and longitudinal project. All attendants responded to digital sociodemographics and COVID-19 questionnaires, the Extended Physician Well-Being Index (EPWBI), and the Post-traumatic Stress Disorder (PTSD) TOP-8 index. Results Of the 507 health workers that participated, 70.02% of them were at risk of burnout according to the Extended Well-Being Index and 57.31, 7.91 and 2.77% had a mild, moderate, and severe risk of PTSD, respectively. The most affected were the female health workers, from metropolitan or central areas of the country, and those diagnosed with COVID-19 or exposed to a person with the diagnosis. Discussion and conclusion Mexican health workers attending mindfulness sessions presented high frequencies of PTSD symptoms and burnout. Female workers at urban hospitals could be at a special risk for developing PTSD or Well-ness alterations, and thus, they must be cared for closely, particularly those having direct contact with COVID 19 positive persons. The early participation in mental health strategies might lessen the immediate and long-term pandemic effects.

Resumen Introducción En México se crearon cinco clínicas virtuales de salud mental para los trabajadores de la salud como parte de la respuesta nacional de salud mental ante la pandemia por COVID-19. La clínica de desgaste, estrés postraumático y fatiga por compasión es una de ellas. Objetivo Describir las características sociodemográficas y psicológicas basales de los trabajadores de la salud que asistieron a las sesiones virtuales de atención plena, que constituyeron una de las estrategias de atención en la clínica. Método Estudio transversal, parte de un proyecto nacional y longitudinal. Los participantes contestaron un cuestionario digital con preguntas sociodemográficas y sobre la situación actual del COVID-19, el Índice Extendido de Bienestar Médico y la escala TOP-8 de estrés postraumático. Resultados De los 507 trabajadores de la salud que participaron, 70.02% presentaron riesgo de desgaste según el Índice de Bienestar Extendido, y 57.31, 7.91 y 2.77% de riesgo leve, moderado y grave en el TOP-8, respectivamente. Las mujeres, los habitantes de la zona metropolitana o del centro del país, aquellos con diagnóstico de COVID-19 y los expuestos a personas con dicho diagnóstico fueron los más afectados. Discusión y conclusión Los participantes de las sesiones de atención plena presentaron altas frecuencias de síntomas de estrés postraumático y desgaste (burnout). Como las trabajadoras de zonas urbanizadas podrían correr un riesgo especial, debería dárseles un seguimiento especial, en particular a aquellas en contacto directo con personas positivas al COVID-19. La participación temprana en estrategias de salud mental podría amortiguar los efectos inmediatos y de largo plazo de la pandemia.

Factores de riesgo asociados a trastornos temporomandibulares / Risk factors associated to temporomandibular joint

Los trastornos temporomandibulares son altamente frecuentes, constituyen un importante problema de salud a nivel mundial y son de etiología multifactorial. Se realizó un estudio analítico observacional tipo casos y controles en la Clínica de Especialidades Estomatológicas Manuel Cedeño de Bayamo, Granma desde marzo 2015 hasta diciembre 2016, con el objetivo de identificar la asociación de algunos factores de riesgo con la aparición de trastornos temporomandibulares en pacientes de 20 a 59 años de edad. El universo estuvo constituido por 167 pacientes y la muestra por 90 individuos, 30 casos y 60 controles. Se utilizó la regresión logística binaria o análisis univariado. Las variables empleadas fueron edad, sexo, trastornos temporomandibulares, condiciones oclusales, estrés y traumas. El grupo de edad de 44 a 51 años y el sexo femenino fueron los más afectados por los trastornos temporomandibulares. Las condiciones oclusales, el estrés emocional y los traumas constituyeron factores de riesgo altamente significativos. No hubo factor de riesgo con carácter protector(AU)

Temporomandibular disorders are highly frequent, are a major health problem worldwide and are of multifactorial etiology. An observational analytical study of cases and controls was carried out at the Manuel Cedeño Stomatological Specialist Clinic of Bayamo, Granma from March 2015 to December 2016, with the aim of identifying the association of some risk factors with the appearance of temporomandibular disorders in patients with 20 to 59 years old. The universe was constituted by 167 patients and it was shown by 90 individuals, 30 cases and 60 controls. We used binary logistic regression or univariate analysis. The variables used were age, sex, temporomandibular disorders, occlusal conditions, stress and traumas. The age group of 44 to 51 years and the female sex were the most affected by temporomandibular disorders. Occlusal conditions, emotional stress and traumas were highly significant risk factors. There was no risk factor with protective character(EU)

Ibero-American initiative for dual disorders to improve public treatment programs / Iniciativa iberoamericana en patología dual para el mejoramiento de los programas públicos de tratamiento

Abstract Introduction: Dual disorders (DD) are defined as the co-occurrence of substance use disorders with other psychiatric disorders across the lifespan. DD represent a diagnostic dimension with clinical peculiarities and specific healthcare needs, which raises the need to implement integrative treatment algorithms. However, worldwide, most programs address this condition through serial or parallel approaches. In Latin America, as in the rest of the world, there is no health care network that adequately addresses this problem. Objective: To describe the development of the initiative for the integral treatment of DD in Latin America. Method: The Organización Panamericana de la Salud (Pan American Health Organization), together with other collaborating organizations, implemented a three-stage plan for developing a regional initiative: 1. meeting of DD experts, 2. review of the literature on DD, and 3. identification of services for DD care in Latin America. Results: The creation of the Iniciativa Iberoamericana para la Patología Dual (Ibero-American Initiative for Dual Disorders) seeks to implement four lines of action to improve of public services: a) build a theoretical-conceptual consensus on DD, b) propose a treatment model, c) develop skills-based training, and d) create collaborative networks for research on DD. Discussion and conclusion: The following actions include the formation of working groups to create a regional collaborative network, discuss the role of participating organizations and establish guidelines for the implementation of the initiative.

Resumen Introducción: La patología dual (PD) se define como la coocurrencia de trastornos por uso de sustancias con otros trastornos psiquiátricos a lo largo del ciclo vital. La PD representa una dimensión diagnóstica con peculiaridades clínicas y necesidades asistenciales específicas, lo que implica la necesidad de implementar algoritmos de tratamiento integrativos. Sin embargo, la mayoría de los programas en el mundo ofrecen sólo modelos que atienden de forma serial o paralela esta condición. En Latinoamérica, como en el resto del mundo, no se cuenta con una red de atención sanitaria que aborde correctamente esta problemática. Objetivo: Presentar el desarrollo de la iniciativa para el abordaje integral de la PD en Latinoamérica. Método: La Organización Panamericana de la Salud, junto con otras organizaciones colaboradoras, implementó un plan de trabajo de tres etapas para generar una iniciativa regional: 1. reunión de expertos en PD, 2. revisión de la literatura sobre PD, y 3. identificar los servicios para atender la PD en Latinoamérica. Resultados: Se generó una Iniciativa Iberoamericana para la Patología Dual. Ésta pretende implementar cuatro líneas de acción para mejorar los servicios públicos: a) generar un consenso teórico-conceptual sobre PD, b) proponer un modelo de tratamiento, c) desarrollar un entrenamiento basado en competencias, y d) crear redes de colaboración para la investigación en PD. Discusión y conclusión: Las siguientes acciones incluyen la conformación de grupos de trabajo para crear una red colaborativa regional, discutir el rol de las organizaciones participantes y establecer lineamientos para la implementación de la iniciativa.

Utilización del conocimiento tácito por proveedores de atención a la salud materna: mapeo sistemático de la literatura / Utilization of tacit knowledge by maternal healthcare providers: a systematic mapping of the literature

Introducción: La búsqueda de respuestas eficaces para fortalecer la atención a la salud materna ha incluido diversas fuentes de evidencia para apoyar la toma de decisiones. En este trabajo presentamos un mapeo sistemático de la utilización del conocimiento tácito de los actores involucrados en la atención de la salud materna reportada en la literatura científica. Método: Mapeo sistemático de artículos científicos publicados en inglés y español entre 1971 y 2014 siguiendo las recomendaciones de Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Resultados: Treinta de 793 artículos cumplen los criterios de inclusión. El 60% procede de países de ingresos altos y la población más estudiada fue el personal de salud (66,7%). Encontramos un predominio (62%) de metodologías cualitativas. Se generaron cuatro categorías sobre el uso del conocimiento tácito: propuestas para mejorar la organización del sistema de atención a la salud materna (30%), y la atención que se les brinda a lo largo del continuo de embarazo, parto y puerperio (26,7%); determinación de la percepción y el nivel de competencias profesionales del personal de salud (26.7%); e interacciones del conocimiento tácito y el conocimiento explícito en la toma de decisiones clínicas (16,7%). Conclusiones: Este mapeo muestra que el conocimiento tácito es un enfoque de investigación emergente, innovador y versátil, con mayores avances en los países de ingresos altos, y que encierra interesantes posibilidades de utilización como evidencia para mejorar las intervenciones en salud materna, especialmente en los países de ingresos medios y bajos, donde se requiere fortalecerlo (AU)

Introduction: The search for efficient answers to strengthen maternal health care has included various sources of evidence for decision making. In this article, we present a systematic mapping of the scientific literature on the use of tacit knowledge in relation to maternal healthcare. Methods: A systematic mapping was conducted of scientific articles published in Spanish and English between 1971 and 2014 following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: Of 793 articles, 30 met the inclusion criteria; 60% were from high-income countries and 66.7% were focused on health professionals. We identified a predominance of qualitative methodologies (62%). Four categories regarding the use of tacit knowledge were generated: proposals to improve the organization of the maternal care system (30%) and to improve the care provided to women during the continuum of pregnancy, childbirth and postpartum (26.7%), determination of health workers’ perception and skill levels (26.7%) and the interactions between tacit and explicit knowledge in clinical decision making (16.7%). Conclusions: This mapping shows that tacit knowledge is an emerging, innovative and versatile research approach used primarily in high-income countries and that includes interesting possibilities for its use as evidence to improve maternal healthcare, particularly in middle- and low-income countries, where it needs to be strengthened (AU)

Sensitivity and Specificity Improvement in Abdominal Obesity Diagnosis Using Cluster Analysis during Waist Circumference Cut-Off Point Selection.

INTRODUCTION: The purpose of this study was to analyze the influence of metabolic phenotypes during the construction of ROC curves for waist circumference (WC) cutpoint selection. MATERIALS AND METHODS: A total of 1,902 subjects of both genders were selected from the Maracaibo City Metabolic Syndrome Prevalence Study database. Two-Step Cluster Analysis (TSCA) was applied to select metabolically healthy and sick men and women. ROC curves were constructed to determine WC cutoff points by gender. RESULTS: Through TSCA, metabolic phenotype predictive variables were selected: HOMA2-IR and HOMA2-ßcell for women and HOMA2-IR, HOMA2-ßcell, and TAG for men. Subjects were classified as healthy normal weight, metabolically obese normal weight, healthy and metabolically disturbed overweight, and healthy and metabolically disturbed obese. Final WC cutpoints were 91.50 cm for women (93.4% sensitivity, 93.7% specificity) and 98.15 cm for men (96% sensitivity, 99.5% specificity). CONCLUSIONS: TSCA in the selection of the groups used in ROC curves construction proved to be an important tool, aiding in the detection of MOWN and MHO which cannot be identified with WC alone. The resulting WC cutpoints were <91.00 cm for women and <98.00 cm for men. Furthermore, anthropometry is insufficient to determine healthiness, and, biochemical analysis is needed to properly filter subjects during classification.

[Urticarial syndrome related to Treponema infection]. / Síndrome urticariano asociado con infección por Treponema.

There are cases of patients having urticaria that do not respond satisfactorily to antihistamine treatment suggested by guidelines. In order to expand the search for associated factors, research about possible related infections have been performed. This paper describes the case of two patients evaluated in our center for hives resistant to standard treatment in which syphilis was diagnosed, with remission of urticaria when specific antibiotic treatment was established.

Existen pacientes con urticaria que no se controlan satisfactoriamente con el tratamiento antihistamínico sugerido por las guías. Con el objetivo de ampliar la búsqueda de factores asociados, se realizaron investigaciones de infecciones como posibles implicados. Se describe el caso de dos pacientes atendidos en nuestro servicio por urticaria resistente al tratamiento habitual, en los que se diagnosticó sífilis, con remisión de la urticaria al administrar el tratamiento antibiótico específico.

Glucosamine for osteoarthritis: biological effects, clinical efficacy, and safety on glucose metabolism.

Osteoarthritis is a chronic degenerative disorder that currently represents one of the main causes of disability within the elderly population and an important presenting complaint overall. The pathophysiologic basis of osteoarthritis entails a complex group of interactions among biochemical and mechanical factors that have been better characterized in light of a recent spike in research on the subject. This has led to an ongoing search for ideal therapeutic management schemes for these patients, where glucosamine is one of the most frequently used alternatives worldwide due to their chondroprotective properties and their long-term effects. Its use in the treatment of osteoarthritis is well established; yet despite being considered effective by many research groups, controversy surrounds their true effectiveness. This situation stems from several methodological aspects which hinder appropriate data analysis and comparison in this context, particularly regarding objectives and target variables. Similar difficulties surround the assessment of the potential ability of glucosamine formulations to alter glucose metabolism. Nevertheless, evidence supporting diabetogenesis by glucosamine remains scarce in humans, and to date, this association should be considered only a theoretical possibility.
