Introduction: The presence of hypophosphatemia is strongly related to the occurrence of refeeding syndrome in critically ill patients, in which one of the main risk groups is the elderly population. Objectives: To assess the prevalence of hypophosphatemia and the risk of refeeding syndrome in elderly patients admitted to an intensive care unit. Methods: Prospective observational study carried out in an intensive care unit with elderly patients of both genders using enteral nutritional therapy. Demographic, clinical and biochemical data were collected, and nutritional screening and assessment were performed. The energy and nutrient requirements were calculated and a cutoff point of 90% was adopted to establish the adequacy of the caloric supply. To assess the risk and occurrence of refeeding syndrome, the criteria proposed by the NICE group were used. Statistical analyses were performed using the SPSS 13.0 program, with a 95% confidence interval (CI). Results: 44 patients were studied, of which 34.1% were malnourished; 86.4% of patients started enteral nutritional therapy within 48 hours, with 43.2% of caloric adequacy within 72 hours. Hypophosphatemia was found in 9.1% of patients on admission and in 29.5% after starting the diet. Thus, 88.6% of patients had some risk of developing the refeeding syndrome and 40.9% of them manifested the syndrome. Conclusion: A high prevalence of hypophosphatemia was identified after starting nutritional therapy. In addition, the risk of developing refeeding syndrome was high and its manifestation is similar to data found in the literature.

Resumo: Introdução e objetivo: O estresse oxidativo é uma provável via crítica na patogênese da pré‐eclâmpsia. Evidências têm sugerido que o consumo adequado de antioxidantes é capaz de modular essa condição. Assim, o objetivo da presente pesquisa foi avaliar a ingestão e o coeficiente de variabilidade de nutrientes antioxidantes por gestantes com pré‐eclâmpsia (GCP). Métodos: Estudo transversal realizado na rede pública de saúde do município de Maceió através de inquérito dietético, com aplicação de: recordatórios alimentares de 24 horas, com posteriores ajustes dos nutrientes pelo método da EAR como ponto de corte, e questionário de frequência de consumo de antioxidantes. Resultados: Foram estudadas 90 GCP e 90 gestantes sem pré‐eclâmpsia (GSP), com médias de idade de 25,8 ± 6,7 anos e 24,1 ± 6,2 anos (p = 0,519), respectivamente. Foram observadas baixas médias de consumo de antioxidantes (vitamina A, selênio, zinco e cobre) para GCP e GSP, apesar do maior consumo de vitamina A (p = 0,045) e selênio (p = 0,008) pelas GSP. Adicionalmente, foram observados elevados coeficientes de variabilidade de consumo para ambos os grupos (GCP versus GSP, respectivamente); no entanto, maiores para as GCP de vitamina C (p

Abstract Background: Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. Objective: To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Maceió. Methods: Prospective cohort study carried out in 2014 in the public health network of the city with a sample of pregnant women calculated based on a prevalence of preeclampsia of 17%, confidence level of 90%, power of 80%, and ratio of 1:1. We applied a questionnaire to collect socioeconomic, personal, and anthropometric data, and retrieved perinatal variables from medical records and certificates of live birth. The analysis was performed with Poisson regression and chi-square test considering p values < 0.05 as significant. Results: We evaluated 90 pregnant women with preeclampsia (PWP) and 90 pregnant women without preeclampsia (PWoP). A previous history of preeclampsia (prevalence ratio [PR] = 1.57, 95% confidence interval [95% CI] 1.47 - 1.67, p = 0.000) and black skin color (PR = 1.15, 95% CI 1.00 - 1.33, p = 0.040) were associated with the occurrence of preeclampsia. Among the newborns of PWP and PWoP, respectively, 12.5% and 13.1% (p = 0.907) were small for gestational age and 25.0% and 23.2% (p = 0.994) were large for gestational age. There was a predominance of cesarean delivery. Conclusion: Personal history of preeclampsia and black skin color were associated with the occurrence of preeclampsia. There was a high frequency of birth weight deviations and cesarean deliveries.
