ABSTRACT

Resumo Os objetivos deste estudo foram construir um indicador de envelhecimento ativo e testar sua associação com qualidade de vida e possíveis determinantes segundo gênero. O estudo AGEQOL (Aging, Gender and Quality of Life) entrevistou 2052 indivíduos com 60 anos e mais de idade residentes em Sete Lagoas, MG, Brasil. A associação entre envelhecimento ativo, qualidade de vida e possíveis determinantes foi realizada por meio da regressão logística múltipla, com nível de 5% de significância estatística, separadamente para cada gênero. A maioria dos homens pertenceu ao grupo com envelhecimento ativo (58,0%), enquanto 51,8% das mulheres foram alocadas no grupo com envelhecimento normal (p < 0,001). A qualidade de vida nos domínios Físico, Psicológico e Escore total mantiveram-se associada ao desfecho no modelo final para ambos os gêneros. Entre os homens, os fatores comportamentais e participação comunitária foram preditores positivos para envelhecimento ativo. Mulheres com maior renda, que não sofreram quedas e com participação comunitária tiveram maior chance de pertencer ao grupo com envelhecimento ativo. Conclui-se que qualidade de vida e a participação em grupos são os principais determinantes de envelhecimento ativo, e que os demais fatores determinantes associados são diferentes para cada gênero.


Abstract The scope of this study was to construct an indicator of active aging and assess its association with quality of life and possible determinants according to gender. The AGEQOL (Aging, Gender and Quality of Life) study was used to interview 2052 individuals aged 60 years and older residing in Sete Lagoas in the State of Minas Gerais. The association between active aging, quality of life and possible determinants was performed by multiple logistic regression with a 5% level of statistical significance separately for each gender. Most men were in the active aging group (58%), and 51.8% of women were in the normal aging group (p < 0.001). The quality of life in the Physical, Psychological, and total Score domains remained associated with the outcome in the final model for both genders. Among the men, the behavioral and community participation factors were positive predictors of active aging. Women with higher incomes, who did not suffer falls and engaged in community participation, had a better chance of belonging to the active aging group. The conclusion drawn is that quality of life and participation in groups are the main determinants of active aging, and the other factors associated with active aging are different for each gender.

ABSTRACT

This work addresses the production of prodigiosin from ram horn peptone (RHP) using MO-1, a local isolate in submerged culture. First, a novel gram-negative and rod-shaped bacterial strain, MO-1, was isolated from the body of the grasshopper (Poecilemon tauricola Ramme 1951), which was collected from pesticide-contaminated fields. Sequence analysis of 16S rDNA classified the microbe as Serratia marcescens. The substrate utilization potential (BIOLOG) and fatty acid methyl ester profile (FAME) of S. marcescens were also determined. The effect of RHP on the production of prodigiosin by S. marcescens MO-1 was investigated, and the results showed that RHP supplementation promoted the growth of MO-1 and increased the production of prodigiosin. A concentration of 0.4% (w/v) RHP resulted in the greatest yield of prodigiosin (277.74 mg/L) after 48 h when mannitol was used as the sole source of carbon. The pigment yield was also influenced by the types of carbon sources and peptones. As a result, RHP was demonstrated to be a suitable substrate for prodigiosin production. These results revealed that prodigiosin could be produced efficiently by S. marcescens using RHP.

ABSTRACT

Introudcción. Serratia marcescens es un patógeno oportunista en hospederos inmunocomprometidos y se asocia fundamentalmente a brotes intrahospitalarios con tasas de letalidad elevadas. El propósito del presente estudio fue tipificar 2 poblaciones de S. marcescens de origen clínico aisladas en 2 institutos pediátricos semejantes. Material y métodos. Se empleó el sistema de biotipificación propuesto por Grimont para la caracterización de 65 cepas del Hospital Infantil de México, originalmente clasificadas como Enterobacter sp y 35 cepas del Instituto Nacional de Pediatría aisladas en un brote intrahospitalario. Reesultados. El biogrupo más numeroso en ambas poblaciones fue el A 5/8 y de éste los biotipos A8a y A8b; se observaron variaciones en las proporciones de los biotipos identificados acordes al hospital de aislamiento, así como en los biotipos y patrones de resistencia a los antibióticos en cepas aisladas del mismo pacientes en muestras diferentes. Conclusiones. Del presente estudio se concluye que es importante que en los hospitales se realicen estudios epidemiológicos particulares de sus poblaciones de S. marcescens, pero es más importante aún que se lleve a cabo una correcta identificación de esta bacteria para valorar adecuadamente su importancia como patógeno oportunista en nuestro medio
