Força de preensão manual e estado nutricional em pacientes oncológicos hospitalizados

Objective: To evaluate the nutritional status and functional capacity of hospitalized adult patients. Methods: Cross-sectional study of adult oncology patients at Hospital de Clínicas de Porto Alegre. Patients were evaluated according to Solid Tumors and Hematologic Tumors. The nutritional status was obtained using Patient Generated Subjective Global Assessment, and the functional capacity was evaluated by Handgrip Strength using a Jamar® dynamometer – and the Performance Index of the Eastern Cooperative Oncology Group. Results: This study evaluated 76 patients (56±17 years old, 35.5% female), 63.2% with Solid Tumors and 36.8% with Hematologic Tumors. According to the Patient Generated Subjective Global Assessment, 53.9% of the patients were moderately and severely malnourished and demonstrated functional capacity, according to the Handgrip Strength and Performance Index of the Eastern Cooperative Oncology Group, of 47.9% and 32.2%, respectively. The functional capacity instruments showed a moderate agreement (Kappa=0.427, p<0.001) and positive correlation (r=0.136, p=0.028). Severely malnourished patients had a lower Handgrip Strength when compared to well nourished (24.0±10.4 vs. 34.2±16.6kg, p=0.015). The results were confi rmed among moderately and severely malnourished patients, who were rated at the 40 percentile, considered low functional capacity Conclusion: In this study, hospitalized oncological patients presented poor nutritional status and low functional capacity. The Patient Generated Subjective Global Assessment identifies the nutritional specification earlier. In addition, Handgrip Strength dynamometry can be a useful tool to evaluate the low functional capacity and nutritional status. It can be included in cancer patient’s evaluation, along with other nutritional assessment tools.Objetivo: Avaliar o estado nutricional e capacidade funcional de pacientes adultos oncológicos hospitalizados. Métodos: Estudo transversal em pacientes oncológicos adultos do Hospital de Clínicas de Porto Alegre. Os pacientes foram divididos de acordo com a presença de Tumores Sólidos e Tumores Hematológicos. O estado nutricional foi identificado pela Avaliação Subjetiva Global Produzida pelo Paciente e a capacidade funcional pela Força do Aperto de Mão – medida por dinamometria – e pelo Índice de Desempenho do Eastern Cooperative Oncology Group. Resultados: Foram avaliados 76 pacientes (56±17 anos, 35,5% do sexo feminino), 63,2% apresentaram Tumores Sólidos e 36,8% Tumores Hematológicos. De acordo com a Avaliação Subjetiva Global Produzida pelo Paciente, 53,9% dos pacientes estavam moderadamente e gravemente desnutridos e demonstraram baixa capacidade funcional de acordo com a Força do Aperto de Mão e Índice de Desempenho do Eastern Cooperative Oncology Group, 47,9% e 32,2%, respectivamente. Os instrumentos de capacidade funcional demonstraram uma concordância moderada (Kappa=0,427; p<0,001) e correlação positiva (r=0,136; p=0,028). Pacientes gravemente desnutridos demonstraram ter uma menor Força do Aperto de Mão quando comparados aos bem nutridos (24,0±10,4 vs. 34,2±16,6kg; p=0,015). Resultados foram confirmados entre pacientes moderadamente e gravemente desnutridos que apresentaram Força do Aperto de Mão abaixo do percentil 40, considerado uma baixa capacidade funcional Conclusão: Neste estudo, os pacientes oncológicos hospitalizados, independentes do tipo de tumor, apresentaram comprometimento do estado nutricional e baixa capacidade funcional. A Avaliação Subjetiva Global Produzida pelo Paciente identifica de forma mais precoce a necessidade de uma intervenção nutricional especifica. Ainda, a Força do Aperto de Mão deve ser considerada para complementar a avaliação nutricional neste grupo de pacientes

Duas variantes do Escore de Risco Nutricional em Pacientes Críticos como preditoras de mortalidade em pacientes admitidos em uma unidade de terapia intensiva de um hospital universitário brasileiro

Objective To evaluate the agreement between the modified version of the Nutritional Risk in the Critically Ill Score (without Interleukin-6) and a variant composed of C-Reactive Protein as well as its capacity to predict mortality. Methods A prospective cohort study was carried out with 315 patients in an Intensive Care Unit of a university hospital from October 2017 to April 2018. The agreement between the instruments was evaluated using the Kappa test. The predictive capacity for estimating mortality was assessed with the Receiver Operating Characteristic curve. Results The critical patients involved in the study had a mean age of 60.8±16.3 years and 53.5% were female. Most patients had C-Reactive Protein levels ?10mg/dL (n=263, 83.5%) and their admission in the Intensive Care Unit was medical (n=219, 69.5%). The prevalence of mortality was observed in 41.0% of the evaluated patients. The proportions at high nutritional risk according to Nutritional Risk in the Critically Ill without Interleukin-6 and with C-Reactive Protein were 57.5% and 55.6%, respectively. The tools showed strong and significant agreement(Kappa=0.935; p=0.020) and satisfactory performances in predicting mortality (area under the curve 0.695 [0.636-0.754] and 0.699 [0.640-0.758]). Conclusion Both versions of the Nutritional Risk in the Critically Ill tool show a satisfactory agreement and performance as predictors of mortality in critically ill patients. Further analysis of this variant and the association between nutrition adequacy and mortality is needed.Objetivo Avaliar a concordância entre a versão modificada do Escore de Risco Nutricional em Pacientes Críticos (sem Interleucina-6) e uma variante composta de Proteína C-Reativa, bem como a capacidade de ambas as versões para predizer mortalidade em pacientes críticos. Métodos Trata-se de um estudo de coorte prospectivo em 315 pacientes admitidos em uma Unidade de Tratamento Intensivo de um hospital universitário brasileiro no período de outubro de 2017 a abril de 2018. A concordância entre os instrumentos foi avaliada pelo teste Kappa. A capacidade preditiva de mortalidade foi avaliada pela curva Receiver Operating Characteristic. Resultados Os pacientes apresentaram idade média de 60,8±16,3 anos, dos quais 53,5% eram mulheres. A maioria dos pacientes apresentou níveis de Proteína C-Reativa ?10mg/dL (n=263; 83,5%). O tipo de admissão na Unidade de Terepia Intensiva foi clínica (n=219; 69,5%), sendo que a prevalência da mortalidade foi observada em41,0% dos pacientes avaliados. O alto risco nutricional, avaliado pelo Nutritional Risk in the Critically Ill sem Interleucina-6 e pela variante com Proteína C-Reativa, foi demonstrado em 57,5% e 55,6% dos pacientes críticos, respectivamente. Os instrumentos demostraram concordância forte e significativa (Kappa=0,935; p=0,020) e desempenho satisfatório para predizer mortalidade (área sob a curva 0,695 [0,636-0,774] e 0,699 [0,640-0,758]). Conclusão Ambas as versões do Escore de Risco Nutricional em Pacientes Críticos apresentam boa concordância e desempenho satisfatório como preditores de mortalidade em pacientes críticos. É ainda necessária uma análise mais aprofundada desta variante, bem como da associação entre adequação nutricional e mortalidade

Relationship between the FTO genotype and early chronic kidney disease in type 2 diabetes : the mediating role of central obesity, hypertension, and high albuminuria

Introduction: Single nucleotide polymorphisms (SNP) in the fat mass and obesity-associated (FTO) gene have been associated with type 2 diabetes (T2D) and its complications. The aim of the present research was to investigate which and how (directly or indirectly) clinical and metabolic variables mediate the association between fat mass and the FTO gene and early chronic kidney disease (CKD) in individuals with T2D. Methods: This cross-sectional study was conducted in a sample of 236 participants with T2D (53.4% women, mean age 60 ± 10 years). DNA samples were genotyped for the rs7204609 polymorphism (C/T) in the FTO gene. Clinical, anthropometric, and metabolic data were collected. Path analysis was used to evaluate the associations. Results: Of the sample, 78 individuals with T2D had CKD (33%). Presence of the risk allele (C) was higher among participants with CKD (21.8 vs. 10.8%; p = 0.023). This polymorphism was positively associated with higher waist circumference, which in turn was associated with higher glycated hemoglobin and higher blood pressure. A higher blood-pressure level was associated with higher urinary albumin excretion (UAE) and as expected, higher UAE was associated with CKD. Path analysis showed an indirect relationship between the FTO gene and early CKD, mediated by waist circumference, blood-pressure levels, and UAE. Conclusions: These findings suggest that the C allele may contribute to genetic susceptibility to CKD in individuals with T2D through the presence of central obesity, hypertension, and high albuminuria

Higher fiber intake is associated with lower blood pressure levels in patients with type 1 diabetes

Objective: The present investigation sought to evaluate the potential association between dietary fiber intake and blood pressure (BP) in adult patients with type 1 diabetes (T1D). Subjects and methods: A cross-sectional study was carried out in 111 outpatients with T1D from Porto Alegre, Brazil. Patients were predominantly male (56%) and white (88%), with a mean age of 40 ± 10 years, diabetes duration of 18 ± 9 years, BMI 24.8 ± 3.85 kg/m2, and HbA1c 9.0 ± 2.0%. After clinical and laboratory evaluation, dietary intake was evaluated by 3-day weighed-diet records, whose reliability was confirmed by 24-h urinary nitrogen output. Patients were stratified into two groups according to adequacy of fiber intake in relation to American Diabetes Association (ADA) recommendations: below recommended daily intake (< 14g fiber/1000 kcal) or at/above recommended intake (≥ 14g/1000 kcal). Results: Patients in the higher fiber intake group exhibited significantly lower systolic (SBP) (115.9 ± 12.2 vs 125.1 ± 25.0 mmHg, p = 0.016) and diastolic blood pressure (DBP) (72.9 ± 9.2 vs 78.5 ± 9.3 mmHg, p = 0.009), higher energy intake (2164.0 ± 626.0 vs 1632.8 ± 502.0 kcal, p < 0.001), and lower BMI (24.4 ± 3.5 vs 26.2 ± 4.8, p = 0.044). Linear regression modelling, adjusted for age, energy intake, sodium intake, and BMI, indicated that higher fiber intake was associated with lower SBP and DBP levels. No significant between-group differences were observed with regard to duration of diabetes, glycemic control, insulin dosage, or presence of hypertension, nephropathy, or retinopathy. Conclusion: We conclude that fiber consumption meeting or exceeding current ADA recommendations is associated with lower SBP and DBP in patients with T1D

O elevado risco nutricional está associado a desfechos desfavoráveis em pacientes internados na unidade de terapia intensiva

OBJECTIVE: To evaluate possible associations between nutritional risk and the clinical outcomes of critical patients admitted to an intensive care unit. METHODS: A prospective study was carried out with a cohort comprising 200 patients admitted to a university hospital intensive care unit. Nutritional risk was assessed with the NRS-2002 and NUTRIC scores. Patients with scores ≥ 5 were considered at high nutritional risk. Clinical data and outcome measures were obtained from patients'' medical records. Multiple logistic regression analysis was used to calculate odds ratios and their respective 95% confidence intervals (for clinical outcomes). RESULTS: This sample of critical patients had a mean age of 59.4 ± 16.5 years and 53.5% were female. The proportions at high nutritional risk according to NRS-2002 and NUTRIC were 55% and 36.5%, respectively. Multiple logistic regression models adjusted for gender and type of admission indicated that high nutritional risk assessed by the NRS-2002 was positively associated with use of mechanical ventilation (OR = 2.34; 95%CI 1.31 - 4.19; p = 0.004); presence of infection (OR = 2.21; 95%CI 1.24 - 3.94; p = 0.007), and death (OR = 1.86; 95%CI 1.01 - 3.41; p = 0.045). When evaluated by NUTRIC, nutritional risk was associated with renal replacement therapy (OR = 2.10; 95%CI 1.02 - 4.15; p = 0.040) and death (OR = 3.48; 95%CI 1.88 - 6.44; p < 0.001). CONCLUSION: In critically ill patients, high nutritional risk was positively associated with an increased risk of clinical outcomes including hospital death

Efficacy of single-dose cholecalciferol in the blood pressure of patients with type 2 diabetes, hypertension and hypovitaminoses D

Observational and experimental data reinforce the concept that vitamin D is associated with the pathogenesis of arterial hypertension. We investigated the efect of a single dose of 100,000 IU of cholecalciferol, in ofce blood pressure (BP), and 24-h ambulatory blood pressure monitoring (ABPM) in patients with type 2 diabetes mellitus (DM), hypertension, and hypovitaminosis D. Fortythree patients were randomized to a placebo or cholecalciferol group. BP was assessed by ofce measurements and 24-h ABPM, before and after intervention. At week 8, a greater decrease in median ABPM values was observed in cholecalciferol supplementation than in the placebo group for systolic 24-h (− 7.5 vs. − 1; P= 0.02), systolic daytime (− 7 vs. − 1; P= 0.007), systolic nighttime (− 7.0 vs. 3; P= 0.009), diastolic 24-h (− 3.5 vs. − 1; P= 0.037), and daytime DBP (− 5 vs. 0; P= 0.01). Ofce DBP was also reduced after vitamin D supplementation. A single dose of vitamin D3 improves BP in patients with type 2 diabetes, hypertension, and vitamin D insufciency, regardless of vitamin D normalization. Vitamin D supplementation could be a valuable tool to treat patients with type 2 DM, hypertension, and hypovitaminosis D

Basal metabolic rate in Brazilian patients with type 2 diabetes : comparison between measured and estimated values

ABSTRACT Objectives: The aims of this study are to investigate which of the seven selected predictive equation for estimating basal metabolic rate (BMR) is the best alternative to indirect calorimetry (IC) and to evaluate the dietary energy intake in patients with type 2 diabetes. Subjects and methods: Twentyone patients with type 2 diabetes participated in this diagnostic test study. Clinical and laboratorial variables were evaluated as well as body composition by absorptiometry dual X-ray emission (DXA) and BMR measured by IC and estimated by prediction equations. Dietary intake was evaluated by a quantitative food frequency questionnaire. Data were analyzed using Bland–Altman plots, paired t-tests, and Pearson’s correlation coefficients. Results: Patients were 62 (48-70) years old, have had diabetes for 8 (2-36) yeas, and 52.4% were females. The mean body composition comprised a fat-free mass of 49.8 ± 9.4 kg and a fat mass of 28.3 ± 7.2 kg. The energy intake was 2134.3 ± 730.2 kcal/day and the BMR by IC was 1745 ± 315 kcal/day. There was a wide variation in the accuracy of BMR values predicted by equations when compared to IC BMR measurement. Harris-Benedict, Oxford, FAO/WHO/ UNO equations produced the smallest differences to IC, with a general bias of < 8%. The FAO/WHO/ UNO equation provided the best BMR prediction in comparison to measured BMR. Conclusion: In patients with type 2 diabetes, the equation of the FAO/WHO/UNO was the one closest to the BMR values as measured by IC
