RESUMEN En América Latina, más de 8 millones de personas mayores dependen de los cuidados a largo plazo (CLP), lo que representa el 12% de las personas de 60 años o más y casi el 27% de las de 80 años o más Resulta crucial elaborar estrategias sostenibles para la prestación de CLP en la región, incluida la atención en centros de CLP. Este artículo especial tiene como finalidad determinar las características de la atención prestada en centros de CLP en cuatro países (Brasil, Chile, Costa Rica y México), utilizando los sistemas de información disponibles, así como determinar cuáles son las estrategias adoptadas en estos países para brindar apoyo a la atención en centros de CLP. En esta revisión descriptiva se utilizaron fuentes de datos públicas, de libre acceso y de ámbito nacional para recopilar estimaciones demográficas e información sobre la cobertura de la atención en centros de CLP, así como sobre la disponibilidad de datos de libre acceso acerca de la proporción de personas con necesidades de CLP, el número de centros de CLP y su correspondiente número de residentes. Estos países tienen una proporción de personas mayores superior a la media de América Latina, pero menos centros de CLP de los necesarios para cubrir la demanda. En las encuestas nacionales no hay una definición estandarizada de la discapacidad, los cuidados a largo plazo y la dependencia. La mayor parte de la información sobre la atención en centros de CLP está fragmentada y no incluye datos periódicos sobre los centros de CLP existentes, sus residentes o sus trabajadores. Estos datos son cruciales para fundamentar decisiones basadas en la evidencia destinadas a propiciar la priorización y brindar apoyo a los avances en la promoción de políticas en materia de centros de CLP en América Latina. Aunque la información sobre la atención en centros de CLP en la región es fragmentaria e insuficiente, en este artículo se presenta el perfil de los cuatro países seleccionados. Se resalta la necesidad de mejorar la estructura de los sistemas de información sobre CLP basados en datos. Esta falta de información pone de relieve la necesidad urgente de centrarse en este tema y fomentar la investigación al respecto.

ABSTRACT More than 8 million older people in Latin America depend on long-term care (LTC), accounting for 12% of people aged ≥ 60 years and almost 27% of those aged ≥ 80. It is crucial to develop sustainable strategies for providing LTC in the area, including institutional care. This special report aims to characterize institutional LTC in four countries (Brazil, Chile, Costa Rica and Mexico), using available information systems, and to identify the strategies adopted to support institutional care in these countries. This narrative review used nationwide, open-access, public data sources to gather demographic estimates and information about institutional LTC coverage and the availability of open-access data for the proportion of people with LTC needs, the number of LTC facilities and the number of residents living in them. These countries have a larger share of older people than the average in Latin America but fewer LTC facilities than required by the demand. National surveys lack standardization in defining disability, LTC and dependency on care. Information about institutional care is mainly fragmented and does not regularly include LTC facilities, their residents and workers. Data are crucial to inform evidence-based decisions to favor prioritization and to support advances in promoting policies around institutional LTC in Latin America. Although information about institutional care in the region is fragmented and insufficient, this paper profiles the four selected countries. It highlights the need for a better structure for data-driven LTC information systems. The lack of information emphasizes the urgency of the need to focus on and encourage research into this topic.

RESUMO Na América Latina, mais de 8 milhões de pessoas idosas dependem de cuidados de longa duração (CLD), o que representa 12% das pessoas com mais de 60 anos e quase 27% das pessoas com mais de 80 anos. É fundamental criar estratégias sustentáveis para oferecer CLD na região, inclusive cuidados institucionais. O objetivo deste relatório especial é caracterizar CLD institucionais em quatro países (Brasil, Chile, Costa Rica e México), usando os sistemas de informação disponíveis, e identificar as estratégias adotadas para apoiar os cuidados institucionais nesses países. Esta revisão narrativa usou dados públicos de acesso aberto de âmbito nacional para coletar estimativas demográficas e informações sobre a cobertura de CLD institucionais e a disponibilidade de dados de acesso aberto sobre a porcentagem de pessoas com necessidades de CLD, o número de instituições de CLD e o número de residentes nessas instituições. Esses países têm uma parcela maior de pessoas idosas do que a média da América Latina, mas menos instituições de CLD do que a demanda exige. Falta padronização na definição de incapacidade, CLD e dependência de cuidados nas pesquisas nacionais. Em sua maior parte, as informações sobre cuidados institucionais são fragmentadas e não incluem instituições de CLD, seus residentes e trabalhadores de maneira regular. É essencial usar dados para guiar decisões baseadas em evidências a fim de favorecer a priorização e apoiar avanços que promovam políticas para CLD institucionais na América Latina. Embora as informações sobre cuidados institucionais na região sejam fragmentadas e insuficientes, este documento traça o perfil dos quatro países selecionados, destacando a necessidade de uma estrutura melhor para sistemas de informações de CLD orientados por dados. A falta de informações ressalta a urgência de aumentar o foco no tópico e encorajar pesquisas sobre o assunto.

ABSTRACT Background: Insulin resistance is key in the pathogenesis of the metabolic syndrome and cardiovascular disease. Objective: We aimed to identify glucose and insulin patterns after a 5-h oral glucose tolerance test (OGTT) in individuals without diabetes and to explore cardiometabolic risk factors, beta-cell function, and insulin sensitivity in each pattern. Methods: We analyzed the 5-h OGTT in a tertiary healthcare center. We identified classes using latent class trajectory analysis and evaluated their association with cardiometabolic risk factors, beta-cell function, and insulin sensitivity surrogates by multinomial logistic regression analysis. Results: We included 1088 5-h OGTT performed between 2013 and 2020 and identified four classes. Class one was associated with normal insulin sensitivity and secretion. Class two showed hyperglycemia, dysinsulinism, and a high-risk cardiometabolic profile (obesity, hypertriglyceridemia, and low high-density lipoprotein [HDL] cholesterol). Class three included older individuals, a higher proportion of males, and a greater prevalence of hypertension, hyperglycemia, hyperinsulinemia, and postprandial hypoglycemia. Finally, class four showed hyperglycemia, dysinsulinism, and hyperinsulinemia; this class had the worst cardiometabolic profile (a high proportion of males, greater age, hypertension, obesity, hypertriglyceridemia, and low HDL cholesterol, p < 0.001 vs. other classes). Conclusions: The latent class analysis approach allows the identification of groups with an adverse cardiometabolic risk factor, and who might benefit from frequent follow-ups and timely multidisciplinary interventions.

Abstract Objective: To describe differences in Case Fatality Rate (CFR) for Covid-19 among healthcare subsystems in Mexico City between March and December 2020. Materials and methods: This is a retrospective secondary data analysis from the National Epidemiological Surveillance System data of Covid-19 cases. Information about health provider institutions was retrieved from the Catalogue of Health Establishments (CLUES). Logistic regressions were fitted to determine the association between health subsystems and mortality associated to Covid-19. The analyses were divided between hospitalized and ambulatory patients. Results: The probability of dying from Covid-19 was higher among those treated at Instituto Mexicano del Seguro Social (IMSS) (Hospitalized:OR=5.11, Ambulatory:OR=36.57), Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) (Hospitalized:OR=2.10, Ambulatory:OR=9.19), Secretaría de Salud (SS) (Hospitalized:OR=1.94, Ambulatory:OR=5.29) or other public institutions (Hospitalized: OR=1.70, Ambulatory: OR=9.56) than in those treated in private institutions. Conclusions: Differences in healthcare quality and access between health subsystems are profound. It is imperative to increase the capacity and quality of the different health subsystems to improve health outcomes.

Resumen Objetivo: Describir diferencias en letalidad por Covid-19 entre subsistemas de salud en la Ciudad de México entre marzo y diciembre de 2020. Material y métodos: Análisis secundario retrospectivo del Sistema Nacional de Vigilancia Epidemiológica sobre casos Covid-19. La información sobre instituciones proveedoras de salud fue obtenida del Catálogo de Establecimientos de Salud. Se ajustaron regresiones logísticas para determinar la asociación entre los subsistemas de salud y la mortalidad atribuida a Covid-19. Los análisis se dividieron entre pacientes hospitalizados y ambulatorios. Resultados: La probabilidad de morir fue mayor entre aquéllos atendidos en el Instituto Mexicano del Seguro Social (IMSS) (Hospitalizados: OR=5.11, Ambulatorios: OR=36.57), Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) (Hospitalizados: OR=2.10, Ambulatorios: OR=9.19), Secretaría de Salud (SS) (Hospitalizados: OR=1.94, Ambulatorio: OR=5.29) u otras instituciones públicas (Hospitalizados: OR=1.70, Ambulatorio: OR=9.56) que en los atendidos en instituciones privadas. Conclusiones: Las diferencias en calidad y acceso a la atención médica entre subsistemas de salud son profundas. Urge aumentar la capacidad y la calidad de los subsistemas de salud para mejorar los resultados en salud.

Abstract Introduction: Central aortic arterial stiffness (CAAS) is an independent cardiovascular risk factor. Insulin resistance (IR) contributes to CAAS-associated risk. Objective: To evaluate the association between IR and CAAS in a Mexican population without diabetes. Methods: IR was estimated with Homeostatic Model Assessment 2-Insulin Resistance (HOMA2-IR) and other surrogate markers (Metabolic score for IR [METS-IR], Quantitative Insulin Sensitivity Check Index [QUICKI], triglycerides/glucose index [TyG], TyG*body mass index [TyG*BMI] and triglycerides/high-density lipoprotein cholesterol ratio [TG/HDL-C]). CAAS was evaluated using carotid-femoral pulse wave velocity analysis (PWVcf) and the standardized augmentation index (AI-75). Bivariate correlations were made between surrogate markers and PWVcf. Increased CAAS was defined as PWVcf above the 90th percentile. Thresholds and area under the curve (AUC) were obtained for each surrogate marker in order evaluate their performance in estimating increased CAAS. Results: Three hundred and fifty-eight patients were included. A correlation was found between HOMA2-IR and PWVcf; this correlation was replicated with other surrogate markers. METS-IR and TyG*IMC had the highest degree correlation with PWVcf. When adjustments were made for covariables, the correlations with TyG*IMC, METS-IR, HOMA2-IR and QUICKI maintained significance. HOMA2-IR showed the strongest correlation with AI-75. METS-IR and TyG showed the best AUC. Patients with prediabetes had the highest PWVcf. Conclusions: The relationship between IR and CAAS is present before the onset of diabetes; this association may entail higher cardiovascular risk.

Resumen Antecedentes: La rigidez arterial central aórtica (RACA) es un factor de riesgo cardiovascular independiente. La resistencia a la insulina (RI) contribuye al riesgo asociado a RACA. Objetivo: Evaluar la asociación entre RI y RACA en una población mexicana sin diabetes. Métodos: La RI se estimó con HOMA2-IR y (Homeostatic Model Assessment 2-Insulin Resistance) otros subrogados (METS-IR [Metabolic score for IR], QUICKI [Quantitative Insulin Sensitivity Check Index], TyG [ratio triglicéridos/glucosa], TyG*IMC [TyG*índice de masa corporal] y TG/HDL [ratio TG/lipoproteínas de alta densidad]). Se evaluó la RACA mediante el análisis de velocidad de onda del pulso carotídeo-femoral (VOPcf) y el índice de aumentación estandarizado (AI-75). Se realizaron correlaciones bivariante entre los subrogados y la VOPcf. RACA aumentada se definió como VOPcf arriba del percentil 90. Se obtuvieron puntos de corte y área bajo la curva (ABC) para cada subrogado para estimar RACA aumentada. Resultados: Se incluyó 358 pacientes. Se encontró una correlación entre HOMA2-IR y VOPcf; esta correlación se replicó con los subrogados. METS-IR y TyG*IMC tuvieron el mayor grado de correlación con VOPcf. Al ajustar, las correlaciones con TyG*IMC, METS-IR, HOMA2-IR y QUICKI mantuvieron significancia. La correlación con AI-75 fue mayor para HOMA2-IR. METS-IR y TyG mostraron la mejor ABC. Los pacientes con prediabetes tuvieron mayor VOPcf. Conclusiones: La relación entre la RI y la RACA está presente desde etapas no diabéticas; esta asociación puede conllevar mayor riesgo cardiovascular.

ABSTRACT Background The International Cholesterol Management Practice Study is a multinational collaborative effort to describe the effectiveness of the lipid-lowering therapy (LLT) as well as the main barriers to achieve the low-density lipoprotein cholesterol (LDL-C) goals Objective The objective of the study was to investigate factors associated with the achievement of LDL-C goals in Mexico using real-life data Methods This was a cross-sectional observational study from 18 physicians across different health facilities in Mexico, who provided information about their practices between August 2015 and August 2016. We included patients treated for ≥3 months with any LLT in whom LDL-C measurement on stable LLT was available for the previous 12 months Results We included 623 patients with a mean age of 59.3 ± 12.7 years; 55.6% were women. The mean LDL-C value on LLT was 141.8 ± 56.1 mg/dL. At enrollment, 97.4% of patients were receiving statin therapy (11.3% on high-intensity treatment). Only 24.8% of the very-high cardiovascular (CV) risk patients versus 26.4% of the high risk and 52.4% of the moderate risk patients achieved their LDL-C goals. Independent factors associated with non-achievement of LDL-C goal were statin intolerance, overweight and obesity, abdominal obesity, female sex, high CV risk, use of public health-care service, metabolic syndrome, type 2 diabetes, and hypertriglyceridemia. Higher-level of education was associated with a lower risk of not achieving LDL-C goals Conclusions Achievement of LDL-C goals is suboptimal in Mexico, especially in patients with the highest CV risk. The main barriers to achieve the goal are easily detectable. Implementation of LLT should be adapted to the patient’s needs and profile.

Objective. To analize the implementation of the Sistema Integral de Calidad en Salud (Sicalidad) program of the Ministry of Health in the 2011. Materials and methods. The study follows a cross sectional design, hybrid, with a qualitative and quantitative components. A cluster probabilístic sample was used with two stages. A total of 3 034 interviews were carried out in 13 states to evaluate the implementation of the eight components of the Sicalidad program. General indexes of performance (GIP) were formulated for structure process and satisfaction of users, physicians and nurses with the program. Results. The GIP with the lower score was accreditation of health facilities with a range of scores between 25.4 and 28% in the medical units evaluated; The highest range of scores was in the component of nosocomial infection prevention between 78.3 and 92%. Conclusion. In brief the Sicalidad components evaluated suggest problems with both structure and critical process elements in the implementation of the quality initiatives.
