ABSTRACT
Abstract Introduction: The mortality of the population with chronic kidney disease (CKD) on hemodialysis (HD) is very high and the protein-energy malnutrition stands out as one of the most common consequences in relation to this condition. Objective: To evaluate the association between time of hemodialysis and nutritional parameters of patients. Methods: It is a cross-sectional study with secondary data, developed of the University Hospital of the Federal University of Juiz de Fora (HU/UFJF). This study was approved by the Research Ethics Committee (Nº 1.233.142), a total of 36 patients. The medical records and collected data were analyzed for anthropometric markers, biochemical and diet, considering two groups: HD time less than three and greater than or equal to three years. Results: There was reduction of mass of somatic protein with increased duration of HD. In relation to food intake was observed that in patients with increased duration of dialysis, an increase in average consumption of protein / kg of weight, calories, phosphorus and potassium, with a significant difference from the mean protein intake / kg (p = 0.04) and phosphorus (p = 0.045). Increasing HD time has altered body composition of patients, indicating a decline in the nutritional status of these individuals. Conclusion: HD patients are a risk group for protein-energy malnutrition, where HD time interferes with the nutritional status and food profile of the patient. The group HD time greater than or equal to 3 years presented worsening nutritional status.
Resumo Introdução: Pacientes com doença renal crônica em hemodiálise (HD) apresentam risco elevado para mortalidade, sendo que a desnutrição protéico-energética se destaca como uma das causa mais comuns em relação a essa condição. Objetivo: Avaliar a associação entre o tempo de hemodiálise e parâmetros nutricionais dos pacientes. Métodos: É um estudo transversal com dados secundários, desenvolvido no Hospital Universitário Federal Universidade de Juiz de Fora (HU / UFJF). Este estudo foi aprovado pela pesquisa Comitê de Ética (nº 1.233.142), um Total de 36 pacientes. Os dados foram coletados por meio dos prontuários médicos, os quais foram analisados marcadores antropométricos, bioquímicos e dieta, considerando dois grupos: tempo HD menor do que três anos e tempo de HD maior ou igual atrês anos. Resultados: Houve redução de massa de proteína somática com aumento do tempo em HD. Em relação à avaliação alimentar, observou-se que em pacientes com maior tempo em diálise houve aumento no consumo médio de proteína/kg de peso, calorias, fósforo e Potássio, com diferença significativa da ingestão média de proteína/kg (p = 0,04) e fósforo (p = 0,045). O tempo em HD alterou a composição corporal dos pacientes, indicando um declínio doestado nutricional desses indivíduos. Conclusão: Pacientes com HD são um grupo de risco para desnutrição protéico-energética, onde o tempo em HD interfere no perfil antropométrico e alimentar do paciente.O grupo com tempo de HD superior ou igual a 3 anos apresentou piora do estado nutricional.

The skin is regarded as the largest organ in our system and has the general purposes of physical, mechanical and immunological protection, sealing against the elements and thermoregulation and tactile perception of environmental stimuli. Skin aging is a complex biological event that affects all skin layers. The dermis, however, is particularly affected due to its histophysiologies' characteristics. With the expansion of life expectancy, the dermatological questions among the older population has had an increasingly bigger importance, propelling the development and perfecting of rejuvenation techniques. The phenol peeling is a deep, chemical one, which offers intense clinical results. The application on small areas of the body, for example, around the eyes, is safe and does not lead to cardiovascular complications. This review aims to update the knowledge of skin histology, the alterations related to photoaging and phenol peeling.
