Reduction of relative handgrip strength and cardiometabolic risk in individuals with HIV/AIDS.

INTRODUCTION: Low handgrip strength (HS) is associated with cardiometabolic alterations that have affected people with HIV/AIDS. METHODS: This was a cross-sectional study performed in adults receiving antiretroviral treatment. HS was evaluated using a dynamometer and divided by body weight to obtain the relative strength. The association between relative HS and overweight, increased waist circumference (WC), high body fat percentage, glycemia, and lipid ratios were assessed using logistic regression. RESULTS: Low relative HS was identified in 35% of participants and associated with increased WC (odds ratio = 9.7; 95% confidence interval = 2.8-33.0). CONCLUSIONS: The prevalence of low HS was high and associated with increased WC.

Ângulo de fase e marcadores tradicionais do estado nutricional em pacientes renais crônicos antes e após a hemodiálise / Phase angle and traditional markers of nutritional status in patients with chronic renal failure before and after hemodialysis

Introdução: Na prática clínica são muitos os métodos utilizados na avaliação de pacientes em hemodiálise, a maioria com limitações. O ângulo de fase, uma variável da bioimpedância elétrica, vem se destacando como importante indicador prognóstico, mas sua relação com marcadores nutricionais é controversa. Objetivo: Avaliar a existência de correlação e concordância entre o ângulo de fase padronizado e marcadores tradicionais do estado nutricional em pacientes renais crônicos, antes e após o tratamento dialítico. Métodos: Estudo transversal com 57 pacientes em hemodiálise, de ambos os sexos, em uma unidade de tratamento dialítico, Salvador, Bahia, Brasil. Os participantes foram avaliados por antropometria, bioimpedância e dinamometria, antes e após a hemodiálise. Foram realizadas análises descritivas, teste T de Student, correlação de Pearson e concordância a partir do coeficiente Kappa. Resultados: Não houve diferença significante no período pré e pós-diálise para as variáveis: circunferência muscular do braço, força do aperto de mão e percentual de massa celular corporal. No período pré-diálise, a correlação foi positiva e fraca entre o ângulo de fase padronizado e o índice de massa corporal, a circunferência muscular do braço, a força do aperto de mão e o percentual de massa celular corporal. No período pós-diálise o percentual de massa celular corporal foi a única variável que não teve correlação estatisticamente significante. A análise de concordância entre o ângulo de fase padronizado e demais parâmetros, no período pré-diálise, mostrou concordâncias pobres ou fracas. No período pós-diálise houve discordância com a percentual de massa celular corporal e concordância moderada com a força do aperto de mão. Conclusão: O ângulo de fase padronizado apresentou correlações fracas com os indicadores antropométricos e moderada concordância com a força do aperto de mão (AU)

Introducion: In clinical practice there are many methods used to assess patients on hemodialysis, most with limitations. The phase angle, a variable of the electric bioimpedance, has been excelling as an important prognostic indicator, but its relation to nutritional markers is controversial. Objective: To evaluate the existence of correlations and concordances between the standard phase angle and traditional markers of nutritional status in patients with chronic renal failure, prior to and following dialysis treatment. Methods: A transversal study with fifty-seven hemodialysis patients, of both sexes, in a dialysis treatment unit, in Salvador, Bahia (Brazil). The participants were evaluated for anthropometry, bioimpedance, and dynamometry, before and after hemodialysis. We performed a descriptive analysis, Student’s t test, Pearson correlation and agreement from the kappa coefficient. Results: There was no significant difference between the pre- and post-dialysis period for the following variables: muscular circumference of the arm, handgrip force, and percentage of cellular body mass. In the pre-dialysis period, the correlation was positive and weak between the standard phase angle and the body mass index, the muscular circumference of the arm, handgrip force, and cellular body mass. In the post-dialysis period the percentage of cellular body mass was the only variable that had no statistically significant correlation. The analysis of concordance between the standard phase angle and other parameters, in the pre-dialysis period, showed poor or weak concordances. In the post-dialysis period there were discordances for the percentage of cellular body mass and moderate concordance for handgrip force. Conclusion: The standard phase angle presented weak correlations with the anthropométric indicators and moderate concordance for handgrip force (AU)

Nutritional assessment in surgical oncology patients: a comparative analysis between methods / Valoración nutricional en pacientes oncológicos quirúrgicos: un análisis comparativo entre métodos

Background and aims: The malnutrition found in oncology patients is the main responsible for the increase in morbimortality and worsening of their quality of life. Currently, the assessment of malnutrition is performed by subjective and objective methods, or the combination of them. Although these methods are routinely applied and their association is very common in clinical practice, there are few studies on the agreement between them. Thereby, this study aims to compare different methods for nutritional status assessment in surgical oncology patients. Methods: 173 oncology patients, admitted for surgery, were submitted to an anthropometric evaluation and answered a SGA, PG-SGA and NRS-2002. Kappa test was used to evaluated the level of concordance between the methods. Results: Poor concordance were observed between BMI and NRS-2002 (K=0,286), SGA (K=0,372) and PGSGA (K=0,173). Among the subjective methods, the best results were found for SGA and PG-SGA (K=0,690), and the lowest between NRS-2002 and both others (SGA: K=0,345; PG-SGA: K=0,322). Conclusions: The poor concordance found between objective and subjective methods reinforces the importance of associating indicators in the nutritional assessment of this population Despite of the poor concordance found between the nutritional status assessment methods investigated in this study, patients who had greater depletion of body stores were also diagnosed with a higher degree of malnutrition by subjective methods (AU)

Introducción y objetivos: La desnutrición en el paciente oncológico es responsable por el aumento de la morbilidady la mortalidady produce una disminución de su calidad de vida. En la actualidad, la identificación de la desnutrición se lleva a cabo por medio de métodos subjetivos y objetivos o por la unión de ambos. A pesar de la asociación de estos métodos como examen de rutina en la práctica clínica, son muy pocos los trabajos que evalúan la concordancia entre ellos. De ese modo, el objetivo de este estudio fue comparar diferentes métodos para evaluar el estado nutricional de los pacientes oncológicos quirúrgicos. Métodos: Se analizaron 173 pacientes oncológicos, ingresados para cirugía, se sometieron a una evaluación antropométrica y respondieron a SGA, PG-SGA y NRS- 2002. Se utilizó el test Kappa para evaluar el nível de concordancia entre los métodos. Resultados: Baja concordancia entre el IMC con el NRS-2002 (K=0,286), ASG(K=0,372) y ASG-PPP (K=0,173) fue identificado. Entre los métodos subjetivos, los resultados fueron mejores com ASG y ASG-PPP (K=0,690) y menor entre el NRS-2002 y los otros (ASG: K=0,345; ASG-PPP: K=0,322). Conclusión: Los resultados demostraron baja concordancia entre los métodos objetivos y subjetivos, lo que refuerza La importancia de la asociación de los indicadores en la evaluación nutricional de esta población. Aunque se ha encontrado baja concordancia entre los métodos de evaluación nutricional empleados en este estudio, los pacientes que presentaron una mayor reducción de las reservas corporales, fueron diagnosticados com un mayor rado de mal nutrición por los métodos subjetivos (AU)
