RESUMO
Abstract: One of the most critical time periods in childhood is from birth to five years of age. Children exposed to alcohol and/or tobacco via family members and neighborhood are at risk for childhood developmental delays. This study evaluated the association of early childhood development with the prevalence of alcohol consumption and tobacco use in Mexican municipalities. This is a cross-sectional study. Early childhood development information from 2,345 children aged from 36 to 59 months was obtained from the 2015 Mexican National Survey of Boys, Girls, and Women (ENIM). Data on alcohol consumption and tobacco use come from the 2016 Mexican National Survey on Drugs, Alcohol, and Tobacco Consumption (ENCODAT). Multilevel logistic models were fitted to evaluate the association of the prevalence of alcohol consumption and tobacco use with the inadequacy of early childhood development. Children living in municipalities with high prevalence of alcohol consumption (OR = 13.410; 95%CI: 2.986; 60.240) and tobacco use (OR = 15.080; 95%CI: 2.040; 111.400) were less likely to be developmentally on track regarding early childhood development after adjustment for individual variables related to the child's development and other environmental variables at municipal level. Childhood exposure to alcohol and tobacco in the neighborhood may directly contribute to inadequate early childhood development. These findings suggest that there is an urgent need to develop effective interventions aimed at reducing alcohol consumption and tobacco use in municipalities to ensure adequate early childhood development.
Resumen: El grupo de edad que se extiende desde el nacimiento hasta los 5 años es uno de los periodos más críticos en la infancia. Niños expuestos al alcohol y/o al tabaco a través de la familia y vecinos corren el riesgo de sufrir un retraso en el desarrollo infantil. Este estudio evaluó la asociación del desarrollo durante la primera infancia con la prevalencia del consumo de alcohol y tabaco en municipios mexicanos. Se trata de un estudio transversal. Las informaciones sobre el desarrollo durante la primera infancia de 2.345 niños de 36 a 59 meses se obtuvieron a través de la Encuesta Nacional de los Niños, Niñas y Mujeres en México (ENIM) de 2015. Los datos sobre el consumo de alcohol y tabaco son de la Encuesta Nacional de Consumo de Drogas, Alcohol y Tabaco en México (ENCODAT) de 2016. Se ajustaron los modelos logísticos multiniveles para evaluar la asociación de la prevalencia de consumo de alcohol y tabaquismo con desarrollo durante la primera infancia inadecuado. Los niños que viven en municipios que tienen una alta prevalencia de consumo de alcohol (OR = 13,410; IC95%: 2,986; 60,240) y tabaquismo (OR = 15,080; IC95%: 2,040; 111,400) se asociaron con la probabilidad más alta de tener un desarrollo durante la primera infancia inadecuado tras el ajuste de las variables individuales relacionadas al desarrollo del niño y a otras variables ambientales en nivel municipal. La exposición infantil al alcohol y al tabaco en la vecindad puede contribuir directamente a un desarrollo durante la primera infancia inadecuado. Estos hallazgos indican una necesidad urgente de desarrollar intervenciones eficaces destinadas a reducir el consumo de alcohol y tabaquismo en los municipios para asegurar un desarrollo durante la primera infancia adecuado.
Resumo: A faixa etária que se estende do nascimento aos 5 anos de idade é um dos períodos mais críticos na infância. Crianças expostas ao álcool e/ou tabaco por meio de familiares e vizinhos estão em risco de atraso no desenvolvimento infantil. Este estudo avaliou a associação do desenvolvimento durante a primeira infância com a prevalência do consumo de álcool e tabaco em municípios mexicanos. Trata-se de um estudo transversal. As informações sobre o desenvolvimento durante a primeira infância de 2.345 crianças de 36 a 59 meses foram obtidas pela Pesquisa Nacional Sobre Crianças e Mulheres no México (ENIM) de 2015. Os dados sobre consumo de álcool e tabaco são da Pesquisa Nacional sobre Consumo de Drogas, Álcool e Tabaco no México (ENCODAT) de 2016. Modelos logísticos multiníveis foram ajustados para avaliar a associação da prevalência de consumo de álcool e tabagismo com desenvolvimento durante a primeira infância inadequado. Crianças que vivem em municípios com alta prevalência de consumo de álcool (OR = 13,410; IC95%: 2,986; 60,240) e tabagismo (OR = 15,080; IC95%: 2,040; 111,400) foram associadas à maior probabilidade de ter um desenvolvimento durante a primeira infância inadequado após ajuste às variáveis individuais relacionadas ao desenvolvimento da criança e a outras variáveis ambientais em nível municipal. A exposição infantil ao álcool e tabaco na vizinhança pode contribuir diretamente para o desenvolvimento durante a primeira infância inadequado. Estas descobertas demonstram uma necessidade urgente de desenvolver intervenções eficazes destinadas a reduzir o consumo de álcool e tabagismo nos municípios para garantir um desenvolvimento durante a primeira infância adequado.
RESUMO
Resumen Las infecciones hospitalarias causadas por bacilos gram negativos resistentes a carbapenems (BGNCR) están asociadas al aumento de morbimortalidad y gasto sanitario. La identificación mediante cultivos de vigilancia y las medidas de control de infecciones permiten reducir su diseminación. El objetivo del estudio fue evaluar el impacto de un programa de vigilancia integrado a protocolos de control de infecciones sobre la incidencia de BGNCR y conocer su epidemiología molecular en una unidad de cuidados intensivos. Se realizaron auditorías seguidas de un programa de cultivo de vigilancia activa y caracterización molecular de BGNCR, antes y después de la implementación de programas de prevención y control de infecciones. El screening microbiológico se realizó en medios cromogénicos; la caracterización molecular de p-lactamasas (blaKPC, bla0XA-48-like, blaVIM, blaiMP, blaNDM, blaSHV y blaCTx-M) por PCR y la tipificación molecular por PFGE y MLST para Klebsiella pneumoniae. El protocolo desarrollado permitió reducir la colonización global de 16,92% al 9,67%. La diseminación de K. pneumoniae fue a expensas de diversos clones portadores de KPC-2 asociada a BLEE SHV-2 y CTX-M-15, y distribuidos en varios secuenciotipos (ST17, ST13, ST2256, ST353); no se observó persistencia de un clon particular y ningún aislamiento presentó factores de virulencia asociados a hipervi-rulencia. Los aislamientos de Acinetobacter baumannii fueron mayoritariamente productores de IMP-1. El análisis PFGE individualizó 3 clusters, asumiendo que la diseminación fue clonal.
Abstract Hospital-acquired infections caused by carbapenem-resistant Gram-negative bacteria (CRGNB) have been increasingly reported worldwide and are associated with high rates of mortality especially in intensive care units(ICUs). Early identification through rectal surveillance cultures and implementation of infection control measures(ICM) including contact precautions, staff education on cleaning and hand hygiene may reduce the spread of these microorganisms. The aim of this work was to assess the impact of enhanced ICM on CRGNB colonization and to describe the molecular epidemiology of these bacteria in a polyvalent ICU in a tertiary level hospital. A prospective study including audits and active surveillance culture program, with molecular characterization, was conducted before and after the implementation of prevention programs and infection control measures. Microbiological screening was performed in chromogenic media; PCR targeting p-lactamases genes (ó/qkpc, óíQndm, blaviM and blaoxA-48, blasHv and ó/qctx-m), molecular typing by PFGE; and MLST in K. pneumoniae were performed. CRGNB colonization was reduced from 16.92% to 9.67% upon implementing the infection control measures. In K. pneumoniae the most frequent carbapenemase type was KPC-2 associated with SHV-2 and CTX-M-15, and was disseminated in various STs (ST17, ST13, ST2256, ST353); there was no persistence of particular clones and virulence factors showed no association with hypervirulence. IMP-1 carbapenemase predominated in A. baumannii and the PFGE analysis individualized 3 clusters, assuming that the dissemination in the ICU was clonal. The early detection of patients colo-nized with CRBGN by using epidemiological surveillance cultures and the implementation of prophylactic measures are key to reducing the incidence of these microorganisms.
