RESUMEN
Resumen Objetivo. Analizar la susceptibilidad in vitro de aislamientos de Candida spp. provenientes de onicomicosis obtenidos entre 2016 y 2019, para contribuir con el conocimiento sobre la necesidad o no de realizar pruebas de susceptibilidad a los microorganismos aislados antes de prescribir el tratamiento. Métodos. El estudio consistió en identificar 23 aislamientos de Candida spp. utilizando el sistema automatizado Vitek2® (bioMérieux, Francia). Se determinó la susceptibilidad in vitro de estos aislamientos ante dos antifúngicos tópicos (amorolfina y ciclopirox) y dos antifúngicos sistémicos (fluconazol e itraconazol) por el método de microdilución en caldo M27-A3 del Instituto Estándares para el Laboratorio Clínico (CLSI por sus siglas en inglés) de los Estados Unidos de América. Resultados. La mayoría de los aislamientos correspondieron a Candida parapsilosis (34,8 %), seguido por C. albicans (30,3 %), C. guilliermondii (17,4 %), C. tropicalis (8,7 %), C. dubliniensis (4,4 %) y C. krusei (4,4 %). No se encontraron diferencias estadísticamente significativas entre las CIMs de los diferentes antifúngicos y en promedio hubo susceptibilidad para todos los antifúngicos analizados. Sin embargo, para fluconazol se encontró un aislamiento con CIM alta de C. guilliermondii y un aislamiento resistente de C. parapsilosis. Conclusiones. Las directrices internacionales recomiendan pruebas de susceptibilidad para Candida spp. de hemocultivos o tejidos tras infecciones sistémicas. En todas las demás candidiasis se identifica la especie y se revisan sus patrones de susceptibilidad en la literatura. Por lo tanto, es de importancia conocer que aislamientos de onicomicosis de Candida no-albicans, especialmente de C. guilliermondii y C. parapsilosis, presentan una susceptibilidad disminuida a ciertos antifúngicos que se utilizan como tratamiento, por lo que se recomienda realizar pruebas de susceptibilidad en caso de no tener una buena respuesta al tratamiento en casos de onicomicosis por estas levaduras.
Abstract Aim. The purpose of this investigation was to determine the in vitro susceptibility patterns of Candida spp. isolated from onychomycosis, in order to contribute with strategies for optimal clinical laboratory management of patients with onychomycosis infected with these yeasts. Methods . A total of 23 isolates of Candida spp. were identified with the automatized system Vitek®2 (system bioMérieux, France). In vitro susceptibility patterns were evaluated with two topic antifungals (amorolfine and ciclopirox) and two systemic antifungals (fluconazole and itraconazole) using the Clinical Laboratory and Standards Institute (CLSI) broth microdilution M27-A3 guidelines. Results . Most of the isolates were identified as Candida parapsilosis (34,8 %), followed by C. albicans (30,3 %), C. guilliermondii (17,4 %), C. tropicalis (8,7 %), C. dubliniensis (4,4 %) and C. krusei (4,4 %). There were no statistically significant differences among the MICs of the antifungals tested. However, there was one isolate of C. guilliermondii with high MIC for fluconazole and one fluconazole resistant isolate of C. parapsilosis. Conclusions. Susceptibility tests are only recommended internationally for Candida spp. isolated from blood stream or tissue in systemic infections. In every other candidiasis there is only a species identification, while its susceptibility pattern for treatment is reviewed in literature. Therefore, it is important to report that Candida no-albicans isolates from onychomycosis, especially C. guilliermondii and C. parapsilosis, have a reduced susceptibility to some antifungals commonly used for treatment. According to the obtained in vitro results, we recommend performing antifungal susceptibility testing in those cases of onychomycosis caused by Candida spp. no responsive to treatment.

OBJECTIVE: To inform decision making regarding intervention strategies against non-communicable diseases in Mexico, in the context of health reform. DESIGN: Cost effectiveness analysis based on epidemiological modelling. INTERVENTIONS: 101 intervention strategies relating to nine major clusters of non-communicable disease: depression, heavy alcohol use, tobacco use, cataracts, breast cancer, cervical cancer, chronic obstructive pulmonary disease, cardiovascular disease, and diabetes. DATA SOURCES: Mexican data sources were used for most key input parameters, including administrative registries; disease burden and population estimates; household surveys; and drug price databases. These sources were supplemented as needed with estimates for Mexico from the WHO-CHOICE unit cost database or with estimates extrapolated from the published literature. MAIN OUTCOME MEASURES: Population health outcomes, measured in disability adjusted life years (DALYs); costs in 2005 international dollars ($Int); and costs per DALY. RESULTS: Across 101 intervention strategies examined in this study, average yearly costs at the population level would range from around ≤$Int1m (such as for cataract surgeries) to >$Int1bn for certain strategies for primary prevention in cardiovascular disease. Wide variation also appeared in total population health benefits, from <1000 DALYs averted a year (for some components of cancer treatments or aspirin for acute ischaemic stroke) to >300,000 averted DALYs (for aggressive combinations of interventions to deal with alcohol use or cardiovascular risks). Interventions in this study spanned a wide range of average cost effectiveness ratios, differing by more than three orders of magnitude between the lowest and highest ratios. Overall, community and public health interventions such as non-personal interventions for alcohol use, tobacco use, and cardiovascular risks tended to have lower cost effectiveness ratios than many clinical interventions (of varying complexity). Even within the community and public health interventions, however, there was a 200-fold difference between the most and least cost effective strategies examined. Likewise, several clinical interventions appeared among the strategies with the lowest average cost effectiveness ratios-for example, cataract surgeries. CONCLUSIONS: Wide variations in costs and effects exist within and across intervention categories. For every major disease area examined, at least some strategies provided excellent value for money, including both population based and personal interventions.

BACKGROUND: Neonatal intensive care improves survival, but is associated with high costs and disability amongst survivors. Recent health reform in Mexico launched a new subsidized insurance program, necessitating informed choices on the different interventions that might be covered by the program, including neonatal intensive care. The purpose of this study was to estimate the clinical outcomes, costs, and cost-effectiveness of neonatal intensive care in Mexico. METHODS AND FINDINGS: A cost-effectiveness analysis was conducted using a decision analytic model of health and economic outcomes following preterm birth. Model parameters governing health outcomes were estimated from Mexican vital registration and hospital discharge databases, supplemented with meta-analyses and systematic reviews from the published literature. Costs were estimated on the basis of data provided by the Ministry of Health in Mexico and World Health Organization price lists, supplemented with published studies from other countries as needed. The model estimated changes in clinical outcomes, life expectancy, disability-free life expectancy, lifetime costs, disability-adjusted life years (DALYs), and incremental cost-effectiveness ratios (ICERs) for neonatal intensive care compared to no intensive care. Uncertainty around the results was characterized using one-way sensitivity analyses and a multivariate probabilistic sensitivity analysis. In the base-case analysis, neonatal intensive care for infants born at 24-26, 27-29, and 30-33 weeks gestational age prolonged life expectancy by 28, 43, and 34 years and averted 9, 15, and 12 DALYs, at incremental costs per infant of US$11,400, US$9,500, and US$3,000, respectively, compared to an alternative of no intensive care. The ICERs of neonatal intensive care at 24-26, 27-29, and 30-33 weeks were US$1,200, US$650, and US$240, per DALY averted, respectively. The findings were robust to variation in parameter values over wide ranges in sensitivity analyses. CONCLUSIONS: Incremental cost-effectiveness ratios for neonatal intensive care imply very high value for money on the basis of conventional benchmarks for cost-effectiveness analysis.

Since 2001, Mexico has been designing, legislating, and implementing a major health-system reform. A key component was the creation of Seguro Popular, which is intended to expand insurance coverage over seven years to uninsured people, nearly half the total population at the start of 2001. The reform included five actions: legislation of entitlement per family affiliated which, with full implementation, will increase public spending on health by 0.8-1.0% of gross domestic product; creation of explicit benefits packages; allocation of monies to decentralised state ministries of health in proportion to number of families affiliated; division of federal resources flowing to states into separate funds for personal and non-personal health services; and creation of a fund to protect families against catastrophic health expenditures. Using the WHO health-systems framework, a wide range of datasets to assess the effect of this reform on different dimensions of the health system was used. Key findings include: affiliation is preferentially reaching the poor and the marginalised communities; federal non-social security expenditure in real per-head terms increased by 38% from 2000 to 2005; equity of public-health expenditure across states improved; Seguro Popular affilates used more inpatient and outpatient services than uninsured people; effective coverage of 11 interventions has improved between 2000 and 2005-06; inequalities in effective coverage across states and wealth deciles has decreased over this period; catastrophic expenditures for Seguro Popular affiliates are lower than for uninsured people even though use of services has increased. We present some lessons for Mexico based on this interim evaluation and explore implications for other countries considering health reforms.

A partir de 2001 se inicia en México un proceso de diseño, legislación e implementación de la Reforma Mexicana de Salud. Un componente clave de ésta fue la creación del Seguro Popular, que pretende extender la cobertura de aseguramiento médico por siete años a la población que no cuenta con seguridad social, la cual constituía en ese momento casi la mitad de la población total. La reforma incluyó cinco acciones: modificar la ley para garantizar el derecho a la protección a la salud para las familias afiliadas, lo cual al ser implantado completamente incrementará el gasto público en salud entre 0.8 y 1.0 por ciento del PIB; la creación de un paquete de servicios de salud explícito; la asignación de recursos a secretarías estatales de salud descentralizadas, proporcional al número de familias incorporadas; la división de los recursos federales destinados a los estados en fondos independientes para servicios de salud personales y no personales; así como la creación de un fondo para garantizar recursos cuando se presentan eventos catastróficos en salud. Mediante el uso del marco conceptual de los sistemas de salud de la OMS, se han examinado diversos conjuntos de datos para evaluar el impacto de esta reforma en distintas dimensiones del sistema de salud. Entre los principales hallazgos clave se encuentran que: la afiliación alcanza de manera preferente a las comunidades pobres y marginadas; el gasto federal no correspondiente a la seguridad social aumentó 38 por ciento de 2000 a 2005 en términos reales; ha mejorado la equidad del gasto público entre los estados; los afiliados al Seguro Popular presentan una mayor utilización de servicios, tanto a nivel ambulatorio como para pacientes externos y pacientes hospitalarios en comparación con los no asegurados; la cobertura efectiva de 11 intervenciones en salud ha mejorado entre 2000 y 2005; han disminuido las desigualdades en cobertura efectiva durante este periodo en todos los estados y deciles...
