Patient-generated subjective global assessment and classic anthropometry: comparison between the methods in detection of malnutrition among elderly with cancer.

INTRODUCTION A comparative study of the various methods of nutritional assessment currently available in oncology are necessary to identify the most appropriate one, as well as the relationships that exist among the different instruments. OBJECTIVE To compare the nutritional diagnosis obtained by the Patient-Generated Subjective Global Assessment (PG-SGA) with the objective anthropometric measurements in the elderly undergoing oncology treatment and to assess the concordance between the methods used in detecting malnutrition. METHODS A cross-sectional study of the elderly, older than or equal to 60 years in age undergoing oncology treatment. The PG-SGA was performed and the anthropometric parameters including weight, height, Body Mass Index (BMI), arm circumference, arm muscle circumference, corrected arm muscle area, arm fat area, calf circumference, waist circumference, hip circumference, waist-hip ratio and triceps skinfold were evaluated. From a 24-hour recall the energy and macronutrient intakes were estimated. RESULTS A total of 96 elderly patients were evaluated. The PG-SGA identified 29.2% with moderate malnutrition or suspected malnutrition and 14.6% with severe malnutrition. From among the elderly evaluated, 47.9% required critical nutritional intervention. The anthropometric parameters and the consumption of energy and macronutrients revealed significant differences based on the subjective PG-SGA classification. The prevalence of malnutrition ranged from 43.8% to 61.4%, depending upon the instrument used. The method most consistent with the diagnosis of malnutrition provided by the PGSGA was the BMI (kappa = 0.54; CI: 0.347-0.648). CONCLUSIONS The PG-SGA showed a significant correlation with the anthropometric measurements and with food consumption for both the categorical classification, as well as for the scoring system. Diagnosis of malnutrition showed variable prevalence depending upon the method used, and none were found equivalent to the PG-SGA.

Impact of Nutrients and Food Components on Dyslipidemias: What Is the Evidence?

Dyslipidemias have been shown to bear a close association with an increased risk of cardiovascular diseases, atherosclerosis in particular. As efforts are being made to find alternative therapies and ways to prevent disease, there is a corresponding rise in public interest in food and/or active food components that contribute to an improved lipid profile and, thus, to better health. Besides supplying the basic nutrients necessary for well-being, some foods add further physiologic benefits. In fact, specific foods and bioactive components could be beneficial in controlling dyslipidemias. From a review of the literature on foods and bioactive compounds, their recommended quantities, and expected effects, we found that the following nutrients and food components could positively impact the lipid profile: monounsaturated and polyunsaturated fatty acids, soluble fiber, vegetable proteins, phytosterols, and polyphenols. Therefore, incorporating these components into the regular diets of individuals is justified, because they contribute additional positive effects. This suggests that they also be recommended in clinical practice.

Women with metabolic syndrome improve antrophometric and biochemical parameters with green banana flour consumption.

BACKGROUND Consumption of green banana flour (GBF) may promote health benefits, such as, decreased appetite, weight loss, glycemic control, intestinal function and lipid profile improvement, aging delay, cancer and heart disease prevention. The aim of this study was to evaluate the effects of green banana flour consumption on anthropometric and biochemical parameters in overweight women. METHODS The glycemic index of flour in the study was determined. The effects of consumption of 20 g of green banana flour/day on weight, body mass index (BMI), blood pressure, waist and hip circumference, body composition, hemoglobin, lipid profile, glucose, insulin, insulin resistance, liver function and energy intake were evaluated in 25 overweight women for 45 days. RESULTS The glycemic index of the flour under study was classified as low. Reduction (p < 0.05) in systolic blood pressure, hip circumference and fasting glucose levels were found in women who had metabolic syndrome criteria. CONCLUSIONS Consumption of green banana flour (20 g/day) for 45 days did not promote weight loss or changes in body composition in overweight women. It was noted, however, decreased hip circumference. Significant health parameter improvements were also noted in individuals with metabolic syndrome, which showed a reduction in systolic blood pressure and fasting glucose.

Depressão, déficit cognitivo e fatores associados à desnutrição em idosos com câncer

The study sought to analyze the presence of depression, cognitive function, nutritional status and factors associated with malnutrition in the elderly undergoing treatment for cancer. A cross-sectional study was conducted in a cancer clinic in Minas Gerais, which included the application of a sociodemographic and health questionnaire, assessment of depressive symptoms, cognitive function and nutritional status. 96 elderly people were evaluated, 50% of which were female and the mean age was 70.6 years. Cognitive impairment was identified in 39.6% and the presence of depression in 17.7%, with a higher number of depressive symptoms in females (p = 0,017). Moderate malnutrition or suspected malnutrition was diagnosed in 29.2%, severe malnutrition in 14.6% and 47.9% had a critical need for nutritional intervention. In multivariate analysis, functional impairment was independently associated with malnutrition (PR: 3.40; CI: 1.23-9.45), the presence of two or more symptoms of nutritional impact (PR: 3.22; CI: 10.03-10.10) and current treatment by chemotherapy (PR: 2.96; CI: 1.16-7.56). The elderly with cancer showed a high prevalence of malnutrition and a need for nutritional intervention. The assessment of depression and cognitive impairment should also be an integral part in addressing this group.The study sought to analyze the presence of depression, cognitive function, nutritional status and factors associated with malnutrition in the elderly undergoing treatment for cancer.

Beginning to Understand the Role of Sugar Carriers in Colletotrichum lindemuthianum: the Function of the Gene mfs1

Fungi of the Colletotrichum genus are among the most prominent phytopathogens that cause diseases with a considerable economic impact, such as anthracnose. The hemibiotrophic fungus Colletotrichum lindemuthianum (teleomorph Glomerella cingulata f. sp. phaseoli) is the causal agent of the anthracnose of the common bean; and similarly to other phytopathogens, it uses multiple strategies to gain access to different carbon sources from its host. In this study, we examine mfs1, a newly identified C. lindemuthianum hexose transporter. The mfs1 gene is expressed only during the necrotrophic phase of the fungus’ interaction within the plant and allows it to utilize the available sugars during this phase. The deletion of mfs1 gene resulted in differential growth of the fungus in a medium that contained glucose, mannose or fructose as the only carbon source. This study is the first to describe a hexose transporter in the hemibiotrophic pathogen C. lindemuthianum and to demonstrate the central role of this protein in capturing carbon sources during the necrotrophic development of the plant/pathogen interaction.

Nutritional risk in pediatrics by StrongKids: a systematic review

Background/objectiveThe nutritional risk in hospitalized children and adolescents is a frequent and under-diagnosed reality. There is still no consensus regarding the best nutritional screening method in pediatrics, with StrongKids being one of the existing proposals. A systematic review was performed to evaluate the scientific evidence about StrongKids, with emphasis on the world frequency of nutritional risk, associations of interest in health, validation and reproducibility studies.MethodsDatabases Pubmed, Lilacs, Scielo, ScienceDirect, Web of Science, Scopus and Cochrane Library were searched, using keyword “StrongKids,” without limit on the year of publication, in English, Spanish, and Portuguese.ResultsFrom 125 papers initially identified, 22 original were included in analysis. The sample size ranged from 43 to 2874, with a maximum of 44 hospitals. The frequency of nutritional risk (medium or high) ranged from 35.7 to 100%. The nutritional risk was mainly associated with acute and/or chronic malnutrition already installed, lower anthropometric indexes and longer length of hospital stay. The method presented satisfactory inter-rater and intra-rater agreements and was validated in the three studies performed with this proposal.ConclusionsThe prevalence of nutritional risk in hospitalized children and adolescents is high. StrongKids is a valid, easy-to-use, and reproducible method, with significant associations of interest in health.

Importância do rastreamento de disfagia e da avaliação nutricional em pacientes hospitalizados

ABSTRACT Objective: To determine frequency of dysphagia risk and associated factors in hospitalized patients as well as to evaluate nutritional status by using different methods and correlate the status with scores of the Eating Assessment Tool (EAT-10). Methods: This was a cross-sectional study including 909 inpatients of a philanthropic hospital. For the diagnosis of dysphagia we used an adapted and validated Brazilian version of the Eating Assessment Tool (EAT-10). The nutritional status was evaluated through the subjective global assessment, and anthropometric measurements included weight, calf and arm circumference, and knee height. The Mann-Whitney test, associations using the Pearson’s χ2 and Spearman’s correlation were used to verify differences between the groups. Results: The prevalence of dysphagia risk was 10.5%, and aging was the associated factor with this condition. Patients at risk presented lower values of arm and calf circumference, variables that correlated inversely with the Eating Assessment Tool (EAT-10) score. Malnutrition was observed in 13.2% of patients based on the subjective global assessment and in 15.2% based on the Body Mass Index. Conclusion: Screening for dysphagia and malnutrition should be introduced in hospitals routine to avoid or minimize damages caused by dysphagia or malnutrition, especially among older people.
