State of malnutrition in hospitals of Ecuador

Rationale: Hospital malnutrition is a global health problem affecting 30-50% of hospitalized patients. There are no estimates of the size of this problem in Ecuadorian hospitals. Hospital malnutrition might influence the quality of medical assistance provided to hospitalized populations. Objectives: To estimate the current frequency of malnutrition among patients admitted to Ecuadorian public hospitals. Materials and methods: The Ecuadorian Hospital Malnutrition Study was conducted between November 2011 and June 2012 with 5,355 patients (Women. 37.5%; Ages ≥ 60 years. 35.1%; Length of stay ≤ 15 days. 91.2%) admitted to 36 public hospitals located in the prominent cities of 22 out of the 24 provinces of the country. Malnutrition frequency was estimated by means of the Subjective Global Assessment survey. Results: Malnutrition affected 37.1% of the surveyed patients. Malnutrition was dependent upon patient's age and education level; as well as the presence of cancer, sepsis, and chronic organic failure. Hospital areas showed different frequencies of hospital malnutrition. Health condition leading to hospital admission influenced negatively upon nutritional status. Malnutrition frequency increased as length of stay prolonged. Conclusions: Malnutrition currently affects an important proportion of patients hospitalized in public health institutions of Ecuador. Policies and actions are urgently required in order to successfully deal with this health problem and thus to ameliorate its negative impact upon quality of medical care

Surgical infection and malnutrition

Background: Malnutrition in surgical patients is associated with delayed recovery, higher rates of morbidity and mortality, prolonged hospital stay, increased healthcare costs and a higher early re-admission rate. Methods: Data synthesis after review of pertinent literature. Results: The aetiology of malnutrition is multifactorial. In cancer patients, there is an abnormal peripheral glucose disposal, gluconeogenesis, and whole-body glucose turnover. Malnourished cancer patients undergoing major operations are at significant risk from perioperative complications such as infectious complications. Surgical aggression generates an inflammatory response which worsens intermediary metabolism. Conclusions: Nutritional evaluation and nutritional support must be performed in all surgical patients, in order to minimize infectious complications. Enteral nutrition early in the postoperative period is effective and well tolerated reducing infectious complications, improving wound healing and reducing length of hospital stay. Pharmaconutrition is indicated in those patients, who benefit from enteral administration of arginine, omega 3 and RNA, as well as parenteral glutamine supplementation. When proximal sutures are used, tubes allowing early jejunal feeding should be used.

Food consumption and risk of malnutrition in community-dwelling very old Spanish adults (≥ 80 years)

Introduction: There are few studies assessing overall diet and food patterns of the oldest population. Objectives: To examine food groups consumption (grams and servings) and their compliance with the dietary guidelines in community-dwelling very old Spanish adults. The relationship with the risk of malnutrition was also studied. Methods: Within the cross-sectional health study of elderly people of Villanueva de la Cañada (Madrid, Spain), in 98 non-institutionalized elders aged ≥ 80 years (66% women) food consumption was calculated from a 24-hour dietary recall and nutritional risk was assessed by Mini Nutritional Assessment (MNA). Statistical significance was evaluated at 95% confidence level (p < 0.05). Results: Men consumed significantly higher amounts of snacks/pickles and alcoholic beverages. The consumption of cereals/grain products (2 servings/day), vegetables (1.5 servings/day) and meat, fish, eggs (1.4 servings/day), was below desirable levels. As nutritional status got worse, fruit consumption was significantly smaller (p = 0.039). Relatively weak but highly significant correlations were found between MNA and oils/fats, fruits and alcoholic beverages. After adjustment for energy intake, oils and fats and fruits associations disappeared whereas a negative association between milk/dairy products and MNA was found. Conclusions: Dietary patterns of the elderly population of Villanueva are departing from the traditional Mediterranean diet and though adequate consumption of fruits, milk/dairy products, oils/fats and sugar/confectionery has been achieved, cereals/grain products, vegetables and the meat,fish,eggs group consumption was below the desirable levels. Deterioration of the nutritional status coincided with a reduction in the consumption of all food groups except for ready meals and milk/dairy products whose consumption increased. Further research on the influence of fruit, milk/dairy products, wine and olive oil consumption on nutritional status is required.

Application of body mass index adjusted for fat mass (BMIfat) obtained by bioelectrical impedance in adults

Introduction: Body mass index (BMI) has been one of the methods most frequently used for diagnose obesity, but it isn't consider body composition. Objective: This study intends to apply one new adiposity index, the BMI adjusted for fat mass (BMIfat) developed by Mialich, et al. (2011), in a adult Brazilian sample. Methods: A cross-sectional study with 501 individuals of both genders (366 women, 135 men) aged 17 to 38 years and mean age was 20.4 ± 2.8 years, mean weight 63.0 ± 13.5 kg, mean height 166.9 ± 9.0 cm, and BMI 22.4 ± 3.4 kg/m². Results and discussion: High and satisfactory R2 values were obtained, i.e., 91.1%, 91.9% and 88.8% for the sample as a whole and for men and women, respectively. Considering this BMIfat were developed new ranges, as follows: 1.35 to 1.65 (nutritional risk for malnutrition), > 1.65 and ≤ 2.0 (normal weight) and > 2.0 (obesity). The BMIfat had a more accurate capacity of detecting obese individuals (0.980. 0.993, 0.974) considering the sample as a whole and women and men, respectively, compared to the traditional BMI (0.932, 0.956, 0.95). Were also defined new cut-off points for the traditional BMI for the classification of obesity, i.e.: 25.24 kg/m² and 28.38 kg/m² for men and women, respectively. Conclusion: The BMIfat was applied for the present population and can be adopted in clinical practice. Further studies are needed to determine its application to different ethnic groups and to compare this index to others previously described in the scientific literature.

Non-institutionalized nonagenarians health-related quality of life and nutritional status: is there a link between them?

Introduction: Nonagenarian population, clearly increasing, shows different characteristics from the rest of elderly people. Health-related quality of life is a way to study population health in physical, psychological and social dimensions. Objectives: To examine the relationship between nutritional status and health-related quality of life in a group of free-living nonagenarians. Differences with octogenarians were also studied. Methods: Within Villanueva Older Health Study, 20 non-institutionalised people (92.5±3.5 years; 80% women) make the nonagenarian subsample. Nutritional risk was assessed by Mininutritional Assessment questionnaire, dietary intake by a 24-hour dietary recall and health-related quality of life by EuroQoL-5D questionnaire. SPSS was used for statistical analysis. Results: 40% nonagenarians were at risk of malnutrition. Dietary assessment showed magnesium, zinc, potassium, folic acid, vitamin D and vitamin E deficiencies. Problems in mobility were more frequently reported (80%). EQ-5Dindex was associated with MNA (p<0.05). Self-care dimension was associated with calcium and niacin (p<0.05), retinol and cholesterol (p<0.01) intake. Usual activities dimension was associated with niacin (p<0.01) and cholesterol(p<0.05) intake. Pain/discomfort dimension was associated with protein (p<0.01), energy, selenium and niacin (p<0.05) intake. Anxiety/depression was associated with protein(p<0.01) and selenium (p<0.05) intake. Conclusions: Risk of malnutrition is a factor associated to health-related quality of life. Results suggest that energy and some nutrient intakes could be possibly associated to health-related quality of life but further research on this influence is required.

Nutritional status and its impact on time and relocation in postoperative complications of abdominal patients undergoing surgery

Introduction: The nutritional state is the independent factor that most influences the post-operational results in elective surgeries. Objective: to evaluate the influence of the nutritional state on the hospitalization period and on the post-operative complications of patients submitted to abdominal surgery. Methods: prospective study with 99 surgical patients over 18 years of age, submitted to abdominal surgeries in the period from April to October of 2013, in the Instituto de Medicina Integral Professor Fernando Figueira (IMIP). All patients were submitted to anthropometric nutritional evaluations through the body mass Index (BMI), arm circumference (AC) and triceps skinfold thickness (TEST). The biochemical evaluation was carried out from the leukogram and serum albumin results. The identification of candidate patients to nutritional therapy (NT) was carried out through the nutritional risk (NR) evaluation by using the BMI, loss of weight and hypoalbuminemia. The information about post-operational complications, hospitalization period and clinical diagnosis was collected from the medical records. Program SPSS version 13.0 and significance level of 5% were used for the statistical analysis. Results: The malnutrition diagnosed by the AC showed significant positive association with the presence of post-operative complications (p=0.02) and with hospitalization period (p=0.02). The presence of NR was greater when evaluated by hypoalbuminemia (28.9%), however, only 4% of the sample carried out the NT in the pre-operational period. The hospitalization period was greater for patients with malignant neoplasia (p<0.01). Conclusion: The malnutrition diagnosis of patients submitted to abdominal surgeries is associated to greater risk of post-operational complications and longer hospitalization permanence.

The influence of the initial state of nutrition on the lifespan of patients with amyotrophic lateral sclerosis (ALS) during home enteral nutrition

Aim: Amyotrophic lateral sclerosis (ALS) is a chronic, neurodegenerative disease, which leads to development of malnutrition. The main purpose of this research was to analyze the impact of malnutrition on the course of the disease and long-term survival. Material and methods: A retrospective analysis has been performed on 48 patients (22 F [45,83%] and 26 M [54,17%], the average age of patients: 66,2 [43-83]) in 2008-2014.The analysis of the initial state of nutrition was measured by body mass index (BMI), nutritional status according to NRS 2002, SGA and concentration of albumin in blood serum. Patients were divided into two groups, depending on the state of nutrition: well-nourished and malnourished. The groups were created separately for each of these, which allowed an additional comparative analysis of techniques used for the assessment of nutritional status. Results: Proper state of nutrition was interrelated with longer survival (SGA: 456 vs. 679 days, NRS: 312 vs. 659 vs. 835 days, BMI: respectively, 411, 541, 631 days, results were statistically significant for NRS and BMI). Concentration of albumin was not a prognostic factor, but longer survival was observed when level of albumin was increased during nutritional therapy. Conclusions: The initial nutrition state and positive response to enteral feeding is associated with better survival among patients with ALS. For this reason, nutritional therapy should be introduced as soon as possible.

One-year follow-up of the nutritional status of patients undergoing liver transplantation

Background: Choosing the method of nutritional assessment is essential for proper follow-up of the nutritional status of patients undergoing liver transplantation. Objectives: Evaluate and compare the nutritional status of cirrhotic patients before and after liver transplantation over a year by different methods of nutritional assessment. Methods: Patients undergoing liver transplantation were assessed in five phases: pre-transplant, 1, 3, 6 and 12 months after transplantation at the hospital Santa Casa de Misericordia de Porto Alegre, RS, Brazil. The methods used for nutritional assessment were anthropometry, grip strength of the non-dominant hand (HGS) by dynamometry, thickness of the adductor pollicis muscle (APM) and phase angle (PA) by bioelectrical impedance analysis (BIA). In all evaluations, the same measurements were taken. Results: Evaluations were performed in 22 patients. Methods that showed a higher prevalence of malnourished patients before transplantation were PA by BIA (25%), arm muscle circumference (AMC) (21.9%) and arm circumference (AC) (18.8%). When comparing the nutritional status of patients during follow-up, there was a significant difference only in the evaluation methods AC, triceps skinfold thickness and PA by BIA. At the end, the methods of nutritional assessment were compared again. They showed a significant statistical difference, with HGS being the best method for detecting malnutrition. Conclusions: In conclusion, it is suggested that the method PA by BIA could be widely used with this population since the results are consistent with other findings in the literature and they are significant, reliable, and reproducible.

Nutritional status in children with esophageal stenosis and dysphagia associated with caustic ingestion

Introduction: Caustic ingestion (CI) in children and adolescents may lead to esophageal burns, esophageal stenosis and secondary dysphagia. These complications may limit the normal feeding process leading to malnutrition and growth impairment. Aims: Our aim was to evaluate the nutritional status and its association with dysphagia and esophageal stenosis in children with CI. Methods: Sixty-two patients with caustic ingestion treated at a pediatric referral hospital were included in this cross-sectional study. Independent variables were dysphagia/normal swallowing and esophageal stenosis/normal barium-swallow. The dependent variables were growth and nutritional status evaluated by anthropometry. Analysis: χ² test, OR, 95% CI, kappa test and Student's t-test. Results: The average age at the time of CI was 39.7 months; 38.7% of the patients were girls. Endoscopy performed upon admission revealed erosive esophagitis (II-b, III-a, and III-b) in 46 (77.8%) of the patients, dysphagia in twenty-four (38.7%) and esophageal stenosis in forty (64.5%). Both complications occurred simultaneously in 20 children (32.3%, kappa = 0.3, p = 0.014). The z-score of height-for-age was below -2 SD in five children (8.1%). The z score of body mass index (BMI) was < -2 SD in three children (4.8%) and it was above +1 SD in 24.2%. The z-score means of the arm anthropometric indicators of fat stores and muscle mass in both the dysphagia and esophageal stenosis groups were located in the negative area of the z-score curve and their values differed significantly from the z-scores of the non-dysphagia and non-stenosis groups. Conclusions: The proportion of erosive esophagitis, esophageal stenosis and dysphagia was high. Children with dysphagia and/or esophageal stenosis associated with CI had lower fat stores and muscle mass than the cases without esophageal complications.

Nutritional assessment of the most frequently consumed dishes in a slum in Iquitos, Peruvian Amazon

Introduction: Large nutritional surveys in Peru have identified the magnitude and location of the different types of malnutrition. The chronic type is the most prevalent one. However, although rates may be considered as alarming (even more in rural areas), only one of these studies contains information about intake characteristics, using 24-hour recalls (R24). That is, it lacks some other systems, adapted to the gastronomical characteristics of their regions and to the bioavailability of food in each area, in order to locate the origin of this situation and, thus, propose truly effective and efficient solutions. Aim: To determine the nutritional value of the main dishes consumed by the residents of a slum in Peruvian Amazon. Methods: Ninety-eight participants completed three 24-h recalls. Based on these data, we selected the 25 most commonly eaten dishes and evaluated their nutritional composition. We took note of the homemade recipes, weights and measures. In addition, we observed preparation and cooking. The mean nutritional composition of each dish was calculated per 100 g using the Nutriplato 4.6. software. We also calculated gains or losses resulting from culinary treatments. Results: Within those which include milk, the highest energy density is the mingado de arroz. In the group of fish, the most energetic is pescado frito, while within meat-based recipes tallarín con pollo, res asada and chancho frito are the most energetic ones. Regarding prepared dishes, the juane is the highest energy density of all recipes. Inside garnish, using bananas as the main ingredient, plátano frito and madurito are the most energetic. Fats are higher in fried dishes and those which contribute most fat ratio. The same thing happens with garnish as 100 grams of plátano frito or madurito contain more than 70% of the RDA. Res asada and juane present the highest sodium level. Conclusions: If we wish to offer healthier dishes, it is necessary to change their composition and/or cooking methods, reducing the consumption of fried foods. Sodium intake should also be reduced. Two foods could be important to that aim: menudencia de pollo, rich in B vitamins and low in fat, and frijol hervido, which is rich in vegetable protein and, with rice dishes ubiquitous in this area, increases the biological value of ingested proteins.

Synbiotic supplementation promotes improvement of chronic diarrhea of unknown etiology in patient with chronic kidney disease and provides better outcomes in dialysis

Background: Chronic kidney disease (CKD) patients often have gastrointestinal symptoms which may result in malnutrition and a negative impact on their quality of life. Modulation of the gut microbiota can be a strategy to promote host health and homeostasis. Case report: The authors present a case of chronic diarrhea in a hemodialysis (HD) patient with an unknown etiology. After about one year and several failed interventions, synbiotic therapy was performed. The diarrhea episodes ceased after three months of daily supplementation and both biochemical and nutritional parameters improved. Synbyotic therapy promoted clinical benefits in this patient. Discussion: Therefore, this simple therapy may be a promising alternative in CKD and it should be tested in larger studies.
