RESUMO

Edible insects are recognized as promising food sources due to their nutritional composition. Some species, such as Gryllus assimilis, contain proteins, lipids, and carbohydrates of high biological value, which regulate several metabolic functions, including the Renin-Angiotensin System (RAS). In this context, the present study aimed to assess the effects of dietary supplementation with whole Gryllus assimilis powder on the metabolism of malnourished mice. Thirty-two male Swiss mice were used and divided into four treatment groups. The groups were identified as (AIN93-M); AIN93-M + Gryllus assimilis diet (AIN93-M + GA); AIN93-M + Renutrition diet (AIN93-M + REN) and AIN93-M + Renutrition diet + Gryllus assimilis (AIN93-M + REN + GA). The results showed that whole Gryllus assimilis powder inclusion promotes recovery from protein-energy malnutrition, reduces adiposity, and improves glucose tolerance and insulin sensitivity. It also reduces total cholesterol, triglycerides, VLDL, and adipocyte area. We also observed a significant increase in the expression of RAS-related genes, such as ACE2 and MasR, followed by a reduction in Angiotensinogen and ACE. The main findings of the present study suggest the use of black cricket as a viable strategy for the prevention and treatment of protein-energy malnutrition, as well as the reduction of adiposity, and improvement of lipid and glycemic parameters, with antihypertensive potential.

RESUMO

BACKGROUND: A secondary care hospital in rural India serving a highly tuberculosis (TB) and malnutrition endemic region. OBJECTIVE: In this study conducted on patients with chronic protein energy malnutrition (PEM) and TB, we sought to compare nurse-estimated vs. smartphone photograph analytic methods for assessing caloric intake and determine the incidence of refeeding hypophosphatemia (RH) and refeeding syndrome (RFS) in patients with TB. METHODS: Inpatients were prospectively enrolled. Baseline demographic, comorbidity and preadmission caloric data were collected. Nurse estimated caloric intake was compared with digital "before and after" meal images. Serum phosphorus was measured on days 1, 3 and 7 post admission. Patients with RH underwent further evaluation for RFS-associated findings. RESULTS: 27 patients were enrolled. 85% were at risk of RFS by National Institute for Health and Care Excellence (NICE) criteria. Significant discrepancy (>700 calories) was noted between nurse-estimated caloric intake compared to digital images. RH was found in 37% (10/27). None developed clinical RFS. CONCLUSIONS: Our study suggests more standardized methods of caloric intake are needed in resource-limited settings with high co-prevalence of PEM and TB. We noted that despite RH being common in inpatients with PEM+TB given high caloric diets, RFS was not detected.

RESUMO

BACKGROUND & AIMS: In dialysis patients, malnutrition is a poor prognostic factor. In patients with chronic kidney disease (CKD), malnutrition is qualitatively different from general malnutrition, which is defined as "Protein-Energy Wasting (PEW)." Dietary therapy for the enhancement of PEW requires the aggressive intake of protein. Conversely, as protein intake and phosphorus intake correlate positively, increasing the protein intake increases the phosphorus intake, which is a poor prognostic factor in dialysis patients. One of the treatments for hyperphosphatemia in dialysis patients is the intake restriction of phosphorus by dietary counseling. However, protein uptake to maintain and augment the nutritional status and the protein intake restriction to correct hyperphosphatemia are contradictory treatments. Hence, this study aims to investigate the effects of PEW and hyperphosphatemia on the prognosis in hemodialysis patients. METHODS: We enrolled 60 outpatients who underwent maintenance hemodialysis for 6 months (May-November 2012) at Iga City General Hospital (Mie, Japan). In November 2012, we assessed the presence or absence of PEW and hyperphosphatemia in patients and evaluated the survival rate over the next 5 years. RESULTS: Overall, 10 patients (17%) were diagnosed as PEW. While 17 patients (28%) exhibited average phosphorus level >6.0 mg/dL (hyperphosphatemia). The 5-year survival rate was 30% in the PEW group, 66% in the non-PEW group, 57% in the hyperphosphatemia group, and 61% in the non-hyperphosphatemia group. A statistically significant difference existed between the PEW and non-PEW groups (P = 0.021). However, we observed no significant difference between the hyperphosphatemia and non-hyperphosphatemia groups. CONCLUSIONS: This study suggests that PEW affects the prognosis more than hyperphosphatemia in maintenance hemodialysis patients. The normalization of the serum phosphorus level by the protein intake restriction could prevent secondary hyperparathyroidism and vascular calcification. Conversely, restricting the protein intake poses a risk of malnutrition. In fact, early death occurred in patients with PEW in this study. Perhaps, patients with PEW should prioritize improving their nutritional status rather than controlling the serum phosphorus level.

RESUMO

OBJECTIVES: Protein and energy malnutrition and unintended weight loss are frequently reported in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). Possible underlying mechanisms include increased energy expenditure, altered uptake of nutrients, a reduced nutritional intake, or a combination of these 3. We aimed at systematically reviewing the literature to examine potential differences in energy and protein intake in patients with MCI and AD compared to controls as a possible mechanism for unintended weight loss. DESIGN: Systematic review and meta-analysis. SETTING: PubMed and Cochrane Electronic databases were searched from inception to September 2017 for case control studies. PARTICIPANTS: Patients with MCI or AD compared to cognitive healthy controls, all adhering to a Western dietary pattern. MEASUREMENTS: Energy and protein intake. RESULTS: The search resulted in 7 articles on patients with AD versus controls, and none on patients with MCI. Four articles found no differences in energy and protein intakes, 1 found higher intakes in patients with AD, and 1 article found lower intakes in patients with AD compared to controls. One article reported on intakes, but did not test differences. A meta-analysis of the results indicated no difference between patients with AD and controls in energy [-8 kcal/d, 95% confidence interval (CI): -97, 81; P = .85], or protein intake (2 g/d, 95% CI: -4, 9; P = .47). However, heterogeneity was high (I2 > 70%), and study methodology was generally poor or moderate. CONCLUSION: Contrary to frequently reported unintended weight loss, our systematic review does not provide evidence for a lower energy or protein intake in patients with AD compared to controls. High heterogeneity of the results as well as of participant characteristics, setting, and study methods was observed. High-quality studies are needed to study energy and protein intake as a possible mechanism for unintended weight loss and malnutrition in both patients with MCI and AD.

RESUMO

Protein-energy wasting (PEW) is a major diet-related complication in hemodialysis (HD) patients. Nutrient-based dietary guidelines emphasize animal-based protein foods for preventing and managing PEW in HD patients. Although dietary protein intake is important for protein anabolism, other dietary factors contribute to PEW. In this article, we examine the diet-related etiologies of PEW in HD patients, and discuss how they may be affected differently by animal- and plant-based protein foods. In general, animal foods are superior sources of protein, but may contribute more to metabolic derangements that cause PEW. Given the potential mixed effects of animal-based protein foods on PEW, human research studies are needed to determine the impact of liberalizing the diet to allow plant-based protein foods on protein status.

RESUMO

Nutritional recovery of early malnutrition with a soybean diet reduces liver glycogen stores in the fed state and produces liver insulin resistance. We investigated whether nutritional recovery on a soybean flour diet alters hepatic gluconeogenesis in the adult offspring of rats deprived of protein during pregnancy and lactation. Male rats from mothers that were fed either 17% (C) or 6% (L) protein during pregnancy and lactation were maintained on a 17% casein (CC, n = 16 and LC, n = 17), 17% soybean flour (CS, n = 10 and LS, n = 10), or 6% casein (LL, n = 10) diet after weaning. The soybean diet reduced basal serum glucose (soybean diet, 5.6 ± 0.6 mmol/L vs. casein diet, 6.2 ± 0.6 mmol/L; p < 0.05) but increased alanine aminotransferase mRNA/GAPDH (soybean diet, 0.062 ± 0.038 vs. casein diet, 0.024 ± 0.011; p < 0.01), phosphoenolpyruvate carboxykinase mRNA/GAPDH (soybean diet, 1.53 ± 0.52 vs. casein diet, 0.95 ± 0.43; p < 0.05), and glycerokinase protein content (soybean diet, 0.86 ± 0.08 vs. casein diet, 0.75 ± 0.11; p < 0.05). The serum glucose concentration (recovered groups, 5.6 ± 0.5 mmol/L vs. control groups, 6.2 ± 0.7 mmol/L; p < 0.05) and phosphoenolpyruvate carboxykinase activity (recovered groups, 2.8 ± 0.6 µU/mg vs. control groups, 3.6 ± 0.6 µU/mg; p < 0.05) were decreased in rats subjected to protein restriction in early life. The glucose area under the curve during the pyruvate tolerance test did not differ among groups, whereas glucose area under the curve after glucagon infusion was reduced by early malnutrition (recovered groups, 4210 ± 572 mg/dL·40 min vs. control groups, 4493 ± 688 mg/dL·40 min; p < 0.001) and by the soybean diet (soybean diet, 3995 ± 500 mg/dL·40 min vs. casein diet, 4686 ± 576 mg/dL·40 min; p < 0.05). Thus, the soybean diet impaired the response to glucagon but did not alter gluconeogenesis.

RESUMO

Chronic kidney disease (CKD) is a global public health burden. Dialysis is not only costly but may not be readily available in developing countries. Even in highly developed nations, many patients may prefer to defer or avoid dialysis. Thus, alternative options to dialysis therapy or to complement dialysis are needed urgently and are important objectives in CKD management that could have huge clinical and economic implications globally. The role of nutritional therapy as a strategy to slow CKD progression and uremia was discussed as early as the late 19th and early 20th century, but was only seriously explored in the 1970s. There is a revival of interest recently owing to encouraging data as well as the increase of precision medicine with an emphasis on a personalized approach to CKD management. Although part of the explanation for the inconclusive data may relate to variations in study design and dietary prescription, diversity in genetic make-up, variations in the non-nutritional management of CKD, intra-individual variations in responses to dietary and nondietary treatment, psychosocial factors, and dietary compliance issues, these all may contribute to the heterogeneous data and responses. This brings in the evolving concept of precision medicine, in which disease management should be tailored and individualized according not only to clinical manifestations but also to the genetic make-up and biologic responses to therapy, which may vary depending on genetic composition. Precision nutrition management also should take into account patient demographics, social, psychological, education, and compliance factors, which all may influence the therapeutic needs and responses to the nutritional therapy prescribed. In this review, we provide a novel concept of precision medicine in nutritional management in end-stage kidney disease with a transition to dialysis and propose how this may be the way forward for nutritional therapy in the CKD population.

RESUMO

OBJECTIVES: To examine care home resident and staff perceptions of the acceptability of participating in a feasibility trial evaluating nutritional interventions in the treatment of malnutrition. DESIGN: Exploratory qualitative methodology was used to gather descriptions of resident and staff perceptions of trial procedures, using semi-structured interviews with residents and focus groups with staff. The interviews were used to explore individual perceptions of the acceptability of the assigned intervention and the outcomes measured. Focus groups were used to explore staff experiences of trial participation and perspectives of nutritional support interventions. SETTING: The study was embedded within a cluster randomised feasibility trial, which randomised six care homes to provide standard care (SC), food-based (FB) intervention or oral nutritional supplement (ONS) intervention to residents with, or at risk of, malnutrition. PARTICIPANTS: Residents in the trial with capacity to consent (n=7) formed the sampling frame for inclusion. Four agreed to be approached by the researcher and to take part in the individual interviews. All were women, representing two arms of the trial (ONS and SC). Twelve staff participated in six focus groups, one at each care home. All participants were women, representing all three arms of the trial. RESULTS: Major themes that emerged from both interviews and focus groups included the perceived acceptability of trial involvement, the value of residents completing participant-reported outcome measures and the challenges associated with outcomes measurement in this setting. Themes that emerged from the focus groups alone, included the importance of individualising an intervention, and the perceived value of FB and ONS interventions and dietetic input. CONCLUSIONS: Residents and staff perceived involvement in a trial evaluating nutritional interventions to be acceptable, although the challenges associated with research in this setting were acknowledged. Resident preferences were highlighted by staff as an important consideration when implementing a nutrition support plan. TRIAL REGISTRATION NUMBER: ISRCTN38047922.

RESUMO

Liver cirrhosis is associated with significant nutritional risks that often result in serious hepatic complications and poor survival rates. Diet is an important but underutilized aspect in the treatment modality of cirrhosis. Therefore, the aims of this review are to ascertain nutritional risks associated with its pathophysiology and to summarize existing evidence that support dietary recommendations for managing this patient population. Alterations in substrate utilization for energy production is a main feature of liver cirrhosis, resulting in increased catabolism of protein stores and a predisposition toward protein-energy malnutrition, even in the early stages of the disease. The body of evidence suggests that a high energy and protein (>1.2 g/kg body weight/d) diet consumed frequently and late in the evening is effective in improving nutritional status of these patients and has been associated with improved hospitalization and mortality rates. The use of branched-chain amino acid supplementation shows promise in reducing cirrhosis-related complications but are currently limited by adverse gastrointestinal symptoms and poor palatability. Furthermore exploration of dietary manipulation of branched-chain amino acid warrants further examination. Evidence is also accumulating that protein intake should not be restricted in patients with hepatic encephalopathy with earlier studies of protein restriction neglecting to account for the relative increase in fermentable fiber which would reduce the absorption of ammonia into the portal system in a way similar to supplementation with lactulose. Finally, a major finding of this review is the need to improve the quality and quantity of dietary intervention studies for patients with liver cirrhosis, particularly with the use of partial or whole dietary sources. In conclusion, dietary management of cirrhosis is not a one-size fits all approach but should be implemented earlier on in the treatment algorithm to improve the clinical prognosis of cirrhosis.

RESUMO

Denutrition for chronic hemodialysed patients is common and severe, often the first step of many complication and comorbidities. This work was aimed to study the impact of the adjunction of hard-boiled egg during six months, at the time of the hemodialysis session, if the classic nutritional support with oral nutritional supplements and intradialytic parenteral nutrition has failed. Required criteria were: Albuminemia, prealbuminemia and Moreau and Gaudry's score. Thirty-six patients have been included. During the six months, the following nutritional parameters have improved: Moreau and Gaudry's score decreased of 0.27, C reactive protein of 9.44 mg/L. Albuminemia improved of 3.53 g/L in average, pre-albuminemia of 0.2 g/L, and normalized Protein catabolic rate of 0.01 g/kg/day. Half of the patients were successful to stop the intradialytic parenteral nutrition. Protein adjunction with hard-boiled egg during chronic hemodialysis session, on top of the classic dietetic support has improved nutritional patient status.

RESUMO

Background: Goals of treating childhood severe acute malnutrition (SAM), in addition to anthropometric recovery and preventing short-term mortality, include reducing the risks of subsequent serious infections. How quickly and how much the risk of serious illness changes during rehabilitation are unknown but could inform improving the design and scope of interventions. Objective: The aim of this study was to investigate changes in the risk of life-threatening events (LTEs) in relation to anthropometric recovery from SAM. Design: This was a secondary analysis of a clinical trial including 1778 HIV-uninfected Kenyan children aged 2-59 mo with complicated SAM, enrolled after the inpatient stabilization phase of treatment, and followed for 12 mo. The main outcome was LTEs, defined as infections requiring rehospitalization or causing death. We examined anthropometric variables measured at months 1, 3, and 6 after enrollment in relation to LTEs occurring during the 6 mo after each of these time points. Results: Over 12 mo, there were 823 LTEs (257 fatal), predominantly severe pneumonia and diarrhea. At months 1, 3, and 6, 557 (34%), 764 (49%), and 842 (56%) children had a weight-for-height or -length z score (WHZ) ≥-2, respectively, which, compared with a WHZ <-3, was associated with lower risks of subsequent LTEs [adjusted HRs (95% CIs): 0.50 (0.40, 0.64), 0.30 (0.23, 0.39), and 0.23 (0.16, 0.32), respectively]. However, children with a WHZ ≥-2 at 1, 3, and 6 mo still had 39 (95% CI: 32, 47), 26 (95% CI: 22, 32), and 15 (95% CI: 12, 20) LTEs/100 child-years of observation during the following 6 mo. WHZ at study enrollment predicted subsequent WHZ but not the risk of LTEs. Changes in height-for-age z score did not predict LTEs. Conclusions: Anthropometric response was associated with a rapid and substantial reduction in risk of LTEs. However, reduction in susceptibility lagged behind anthropometric improvement. Disease events, together with anthropometric assessment, may provide a clearer picture of the effectiveness of interventions. Robust protocols for detecting and treating poor anthropometric recovery and addressing broader vulnerabilities that complicated SAM indicates may save lives. This trial was registered at www.clinicaltrials.gov as NCT00934492.

RESUMO

BACKGROUND: This analysis sets out an overview of an IUNS presentation of a European clinician's assessment of the challenges of coping with immediate critical clinical problems and how to use metabolic and a mechanistic understanding of disease when developing nutritional policies. SUMMARY: Critically ill malnourished children prove very sensitive to both mineral and general nutritional overload, but after careful metabolic control they can cope with a high-quality, energy-rich diet provided their initial lactase deficiency and intestinal atrophy are taken into account. Detailed intestinal perfusion studies also showed that gastroenteritis can be combatted by multiple frequent glucose/saline feeds, which has saved millions of lives. However, persisting pancreatic islet cell damage may explain our findings of pandemic rates of adult diabetes in Asia, the Middle East and Mexico and perhaps elsewhere including Africa and Latin America. These handicaps together with the magnitude of epigenetic changes emphasized the importance of a whole life course approach to nutritional policy making. Whole body calorimetric analyses of energy requirements allowed a complete revision of estimates for world food needs and detailed clinical experience showed the value of redefining stunting and wasting in childhood and the value of BMI for classifying appropriate adult weights, underweight and obesity. Lithium tracer studies of dietary salt sources should also dictate priorities in population salt-reduction strategies. Metabolic and clinical studies combined with meticulous measures of population dietary intakes now suggest the need for far more radical steps to lower the dietary goals for both free sugars and total dietary fat unencumbered by flawed cohort studies that neglect not only dietary errors but also the intrinsic inter-individual differences in metabolic responses to most nutrients. Key Messages: Detailed clinical and metabolic analyses of physiological responses combined with rigorous dietary and preferably biomarker of mechanistic pathways should underpin a new approach not only to clinical care but also to the development of more radical nutritional policies.

RESUMO

BACKGROUND & AIMS: Interventions such as oral nutritional supplements (ONS), fortified meals and mid-meals, feeding assistants and Protected Mealtimes have shown some impact on nutritional intake in research studies, but embedding them in practise remains challenging. This study monitored nutritional intake of older medical inpatients as dietary and mealtime interventions were progressively implemented into routine practise. METHODS: Series of three prospectively evaluated patient cohorts allowed comparison of nutritional intake of 320 consented medical inpatients aged 65 + years: cohort 1 (2007-8), cohort 2 (2009) and cohort 3 (2013-14) as nutrition care interventions were progressively introduced and embedded. Interventions focused on 'assisted mealtimes', fortified meals and mid-meals, and ONS. Energy and protein intake were calculated from visual plate waste of individual meal and mid-meal components on day 5 of admission. Nutrition care processes were evaluated by mealtime audits of diet type, assistance and interruptions on the same day. One-way ANOVA and chi square tests were used for comparison between cohorts. RESULTS: Significant, progressive improvements in energy and protein intake were seen between cohorts (energy: cohort 1: 5073 kJ/d; cohort 2: 5403 kJ/d; cohort 3: 5989 kJ/d, p = 0.04; protein: cohort 1: 48 g/d, cohort 2: 50 g/d, cohort 3: 57 g/d, p = 0.02). Greater use of fortified meals and mid-meals and sustained improvements in mealtime assistance likely contributed to these improvements. CONCLUSIONS: Multi-faceted system-level approach to nutrition care, including changes to dietary and mealtime care processes, was associated with measureable and sustained improvements in nutritional intake of older inpatients over a seven year period.

RESUMO

Background: Malnourished children show variable growth responses to nutritional rehabilitation. We aimed to investigate whether these differences could be explained by variations in growth and energy-regulating hormones. Methods: Quasi-experimental study: Children aged 6-24 months in rural Gambia were recruited to controls if weight-for-height z-score (WHZ) > -2 (n = 22), moderate acute malnutrition if WHZ < -2 and > -3 (n = 18) or severe acute malnutrition if WHZ < -3 (n = 20). Plasma hormone and salivary CRP levels were determined by ELISA. Results: In univariable analyses, increases in weight-for-age z-score (WAZ) in malnourished children were positively correlated with insulin (F-ratio 7.8, p = 0.006), C-peptide (F-ratio 12.2, p < 0.001) and cortisol (F-ratio 5.0, p = 0.03). In multivariable analysis, only baseline C-peptide (F-ratio 7.6, p = 0.009) predicted the changes in WAZ over 28 days of interventions. Conclusion: In rural Gambian, malnourished children, although it cannot be used in isolation, baseline C-peptide was a predictor of future response to rehabilitation.

RESUMO

Severe protein-energy malnutrition (PEM) and skeletal muscle wasting are commonly observed in patients with acute leukemia. Recently, the ingestion of a soy-whey protein blend has been shown to promote muscle protein synthesis (MPS). Thus, we tested the hypothesis that the ingestion of a soy-whey blended protein (BP) may improve the PEM status and muscle mass in acute leukemia patients. In total, 24 patients from the same treatment group were randomly assigned to the natural diet plus soy-whey blended protein (BP) group and the natural diet only (ND) group. Our data showed that protein and energy intake decreased significantly (P < .05) after transplantation in both groups. In the absence of the BP intervention, dramatic decreases in muscle-related indicators (i.e., anthropometric variables, muscle strength and serum protein) were observed in the majority (>50%) of the patients. However, 66% of the patients who ingested the BP before transplantation showed obvious increases in arm muscle area. The gripping power value (△post-pre or △post-baseline) was significantly higher in the BP group than in the ND group (P < .05). The ingestion of the BP also increased the levels of serum albumin, globulin and serum total protein to different extents. Notably, the average time to stem cell engraftment was significantly shorter for patients in the BP group (12.2 ± 2.0 days) than for patients in the ND group (15.1 ± 2.9 days). Collectively, our data supported that soy-whey protein can improve PEM status and muscle mass in leukemia patients.

RESUMO

OBJECTIVE: To investigate the effect of dietary counselling on the nutritional status of end-stage renal disease patients undergoing maintenance haemodialysis. METHODS: This study was conducted at the Institute of Kidney Diseases, Peshawar, Pakistan, from November to December 2015, and comprised patients of either gender with protein energy wasting. The nutritional status assessment was based on four categories, including biochemical indicators (haemoglobin, serum albumin and cholesterol), measure of body mass index, reduced body fatness, decreased muscle mass and low protein or energy intake. Energy and nutrients intake of patients before and after counselling were estimated by 24-hour dietary recall method. SPSS 20 was used for data analysis. RESULTS: Of the 100 patients, 74(74%) were males and 26(26%) were females. The overall mean age was 41.45±17.44 years. Dietary counselling was significantly effective in increasing the intake of energy (p=0.010), protein (p=0.003) and fats (p=0.002). There was significant improvement in mid-upper arm circumference (p<0.0001) and tricep fat fold (p<0.0001) after counselling. Statistically significant effect was seen in improving serum cholesterol levels (p=0.039). CONCLUSIONS: Dietary counselling was found to be effective in improving the nutritional status and dietary intake of end-stage renal disease patients.

RESUMO

OBJECTIVE: To evaluate the effect of individually tailored dietary counseling on nutritional status among home care clients aged 75 years or older. DESIGN: Non-randomised controlled study. SETTING AND PARTICIPANTS: The study sample consisted of 224 home care clients (≥ 75 years) (intervention group, n = 127; control group, n = 100) who were at protein-energy malnutrition (PEM) or risk of PEM (MNA score <24 and plasma albumin <35 g/L). INTERVENTION: Individually tailored dietary counseling; the persons were instructed to increase their food intake with energy-dense food items, the number of meals they ate and their consumption of energy-, protein- and nutrient-rich snacks for six months. MEASUREMENTS: The Mini Nutritional Assessment (MNA), Body Mass Index (BMI) and plasma albumin were used to determine nutritional status at the baseline and after the six-month intervention. RESULTS: The mean age of the home care clients was 84.3 (SD 5.5) in the intervention group and 84.4 (SD 5.3) in the control group, and 70 percent were women in both groups. After the six-month nutritional intervention, the MNA score increased 2.3 points and plasma albumin 1.6 g/L in the intervention group, against MNA score decreased -0.2 points and plasma albumin -0.1 g/L in the control group. CONCLUSIONS: Individually tailored dietary counseling may improve nutritional status among older home care clients.

RESUMO

OBJECTIVE: Protein-energy wasting (PEW) is associated with increased morbidity and mortality and a rapid deterioration of kidney function in patients with chronic kidney disease (CKD). However, there is little information regarding the effect of nutrition intervention. The aims of this study were to evaluate the efficacy and safety of a nutrition education program (NEP) in patients with nondialysis dependent CKD (NDD-CKD), based on the diagnostic criteria for PEW proposed by the International Society of Renal Nutrition and Metabolism. The design of the study was a 6-month longitudinal, prospective, and interventional study. The study was conducted from March 2008 to September 2011 in the Nephrology Department of La Paz University Hospital in Madrid, Spain. SUBJECTS: A total of 160 patients with NDD-CKD started the NEP, and 128 finished it. INTERVENTION: The 6-month NEP consisted of designing an individualized diet plan based on the patient's initial nutritional status, and 4 nutrition education sessions. MAIN OUTCOME MEASURES: Changes in nutritional status (PEW) and biochemical, anthropometric and body composition parameters. RESULTS: After 6 months of intervention, potassium and inflammation levels decreased, and an improved lipid profile was found. Body mass index lowered, with increased muscle mass and a stable fat mass. Men showed increased levels of albumin and prealbumin, and women showed decreased proteinuria levels. The prevalence of PEW decreased globally (27.3%-10.9%; P = .000), but differently in men (29.5%-6.5%; P = .000) and in women (25.4%-14.9%; P = .070), 3 of the women having worsened. Kidney function was preserved, despite increased protein intake. CONCLUSION: The NEP in NDD-CKD generally improved nutritional status as measured by PEW parameters, but individual poorer results indicated the need to pay special attention to female sex and low body mass index at the start of the program.

RESUMO

BACKGROUND: The use of enteral formulas with immunonutrients in patients with gastrointestinal malignancies susceptible to surgery can reduce postoperative morbidity, at the expense of reduced infectious complications, with the consequent reduction in hospital stay and health care costs. MATERIAL AND METHODS: Prospective randomized study. 84 patients operated on a scheduled basis for resectable colorectal cancer were recruited. In the group YES IN Impact © Oral was administered for 8 days (3 sachets a day), compared with the NOT IN group who did not receive it. RESULTS: 40.5% (17) patients without immunonutrition suffered infectious complications vs. 33.3% (14) of YES IN. In patients with rectal cancer NOT IN, 50% (8) suffered minor infectious complications (p=.028). In each group (YES IN, NOT IN, colon and rectal cancer) when infectious complications were observed, the variables total hospital stay and costs doubled, with significant differences. These variables showed higher values in the group NOT IN compared with those who received immunonutrition, although these differences were not statistically significant. CONCLUSIONS: NOT IN patients suffered infectious complications more frequently than YES IN, with significant results in the subgroup of patients with rectal cancer. The total hospital stay and costs were slightly higher in the group not supplemented, doubling in each category significantly (YES IN, NOT IN, colon and rectal cancer), when infectious complications were observed.
