Nutritional status as predictor of quality of life in patients undergoing hemodialysis / Estado nutricional como preditor de qualidade de vida em pacientes em hemodiálise

ABSTRACT Objective: to evaluate the association between quality of life and nutritional status of hemodialysis patients, according to anthropometric and biochemical measurements. Methods: cross-sectional study conducted with 1,024 patients from 11 hemodialysis centers in a metropolitan region of southeastern Brazil. Results: through multiple linear regression, the nutritional predictors of each domain of quality of life were identified. We highlight serum albumin, Body Mass Index (BMI) and waist circumference, among the measures associated with both physical and mental health in this population. Conclusion: inadequate nutritional status is associated with worse physical and mental quality of life in hemodialysis individuals. In addition to monitoring the nutritional status, nutritional assessment predicts quality of life and becomes a fundamental tool for a better health outcome, since low quality of life is one of the main problems in this population. DESCRIPTORS: Quality of life related to health; Renal replacement therapy; Nutritional assessment.RESUMÉN Objetivo: evaluar la asociación entre calidad de vida y estado nutricional de pacientes en hemodiálisis, según medidas antropométricas y bioquímicas. Métodos: estudio transversal realizado con 1.024 pacientes de 11 centros de hemodiálisis de una región metropolitana del sureste de Brasil. Resultados: mediante regresión lineal múltiple, se identificaron los predictores nutricionales de cada dominio de la calidad de vida. Destacamos la albúmina sérica, el índice de masa corporal (IMC) y la circunferencia de la cintura, entre las medidas asociadas a la salud tanto física como mental en esta población. Conclusión: el estado nutricional inadecuado se asocia con una peor calidad de vida física y mental en los individuos en hemodiálisis. Además de monitorear el estado nutricional, la evaluación nutricional predice la calidad de vida y se convierte en una herramienta fundamental para un mejor resultado de salud, ya que la baja calidad de vida es uno de los principales problemas en esta población.

Conclusão: a inadequação do estado nutricional está associado a pior qualidade de vida física e mental de indivíduos em hemodiálise. Além do monitoramento do estado nutricional, a avaliação nutricional prediz a qualidade de vida e torna-se uma ferramenta fundamental para um melhor desfecho de saúde, uma vez que a baixa qualidade de vida é um dos principais problemas desta população.

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
