Metabolic effects of an oral carbohydrate-whey protein supplement after fasting in volunteers: A randomized controlled crossover trial. Nutrition 2024; 117:112251. [PMID: 37944409 DOI: 10.1016/j.nut.2023.112251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 08/16/2023] [Accepted: 09/27/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVE Oral supplements containing carbohydrates (CHOs) can be used to reduce preoperative fasting time. The aim of this study was to investigate the early metabolic and acute phase responses to a clear, oral supplement containing CHO and whey protein (WP) in young, healthy volunteers during a fasting-induced organic response. METHODS In this controlled crossover clinical trial, volunteers were randomized into groups after a 12-h fast: the CHO+WP group consumed 200 mL CHO enriched with WP (n = 30); the CHO group members consumed 200 mL water plus maltodextrin (n = 30), and the Fast group was fasted only (n = 30). Blood samples were collected after fasting and 3 h after ingestion of the supplement. The samples were analyzed for glucose, glycated hemoglobin, insulin, C-reactive protein, β-hydroxybutyrate, triacylglycerols, albumin, chlorine, and sodium. After 7 d, the groups were inverted, so all volunteers entered the three groups. RESULTS The nutritional intervention did not change the biochemical parameters related to the acute phase response or insulin resistance; however, there was a statistically significant reduction (P < 0.001) in serum β-hydroxybutyrate in the CHO+WP group (0.05 ± 0.08 mmol/L) compared with the other two groups (Fast group: 0.11 ± 0.08 mmol/L; CHO group: 0.09 ± 0.13 mmol/L). CONCLUSIONS After overnight fasting, the oral supplement containing CHO and WP decreased ketosis. These findings may help select the most efficient oral supplement to be given 2 to 3 h before elective surgeries.

Impact of Nutritional Management on Survival of Critically Ill Malnourished Patients with Refeeding Hypophosphatemia. Arch Med Res 2023; 54:231-238. [PMID: 36805190 DOI: 10.1016/j.arcmed.2023.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 01/31/2023] [Accepted: 02/07/2023] [Indexed: 02/19/2023]
Abstract
BACKGROUND Early nutritional therapy may aggravate hypophosphatemia in critically ill patients. AIM To investigate the influence of the type nutritional therapy on the survival of critically-ill malnourished patients at refeeding hypophosphatemia risk. METHODS Retrospective cohort study including malnourished, critically-ill adults, admitted from June 2014-December 2017 in an intensive care unit (ICU) at a tertiary hospital. Refeeding hypophosphatemia risk was defined as low serum phosphorus levels (<2.5 mg/dL) seen at two timepoints: before the initiation and at day 4 of the nutritional therapy. Patients receiving enteral nutrition (EN) were compared with those receiving supplemental parenteral nutrition (SPN-EN plus parenteral nutrition). Primary outcome was 60 d survival. Secondary endpoint was the incidence of refeeding hypophosphatemia risk. RESULTS We included 468-321 patients (68.6%) received EN and 147 (31.4%) received SPN. The mortality rate was 36.3% (n = 170). Refeeding hypophosphatemia risk was found in 116 (24.8%) patients before and in 177 (37.8%) at day 4 of nutritional therapy. The 60 d mean survival probability was greater for patients receiving SPN both before (42.4 vs. 22.4%, p = 0.005) and at day 4 (37.4 vs. 25.8%, p = 0.014) vs. patients receiving EN at the same timepoints. Cox regression showed a hazard ratio of 3.3 and 2.4 for patients at refeeding hypophosphatemia risk before and at day 4 of EN, respectively, compared to the SPN group at the same timepoints. CONCLUSION Refeeding hypophosphatemia risk was frequent in malnourished ICU patients and the survival for patients receiving SPN seemed associated with better survival than EN only.

Residual gastric volume after 3 h of the ingestion of an oral supplement containing carbohydrates alone or associated with whey protein: a randomized crossover pilot study. Perioper Med (Lond) 2022; 11:56. [PMID: 36575506 PMCID: PMC9793542 DOI: 10.1186/s13741-022-00289-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 12/17/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND New formulas including a nitrogenous source to maltodextrin have been reported as preoperative beverages 2-3 h before anesthesia in the elective procedure. Whey protein is a potential candidate for the composition of this clear oral supplement. This study aimed to investigate the gastric residual volume (GRV) of healthy volunteers 3 h after the ingestion of an oral supplement containing carbohydrates (CHO) alone or combined with whey protein (WP). METHODS This crossover clinical trial design includes young, healthy male volunteers with normal body mass index. Magnetic resonance imaging (MRI) scan of the upper abdomen to measure the GRV was performed in the participants in three phases: (1) after a fasting period of 8 h; (2) immediately after the ingestion of 200 mL of a clear supplement containing: (2a) 10 g of WP and 54 g of CHO (74% glucose and 26% maltodextrin)-WP + CHO group or (2b) 12.5% maltodextrin (25 g)-CHO group; and (3) after 3 h of the ingestion of both types of supplements. A week interval was programmed between phases 2a and 2b. RESULTS There was no significant difference (p = 0.91; within-group comparison) of the mean ± SD of the GRV between phase 1 (WP + CHO: 23.45 ± 14.01; CHO: 25.03 ± 15.17 cm3; p = 0.78; between-groups comparison) and phase 3 (WP + CHO: 25.66 ± 9.31; CHO: 23.45 ± 13.58 cm3, p = 0.86; between-groups comparison). The GRV of phase 2 (WP + CHO: 206.43 ± 23; CHO: 203.99 ± 12.18 cm3; p = 0.82; between-groups comparison) was significantly greater (p < 0.01; within-group comparison) than both other two phases. CONCLUSION The GRV after 3 h of the ingestion of either WP + CHO or CHO oral supplement returns to basal fast condition implying that gastric emptying after this interval of time is significantly completed.

[PMID: 33418494 DOI: 10.1016/j.nut.2020.111054] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 10/07/2020] [Accepted: 10/28/2020] [Indexed: 12/24/2022]
Abstract
OBJECTIVES The aim of this study was to determine sensitivity, specificity, and best cutoff point for adductor pollicis muscle thickness (APMT) for diagnosis of sarcopenia in elderly community centers. METHODS This was a cross-sectional study comprising 321 elderly individuals from four community centers in Cuiabá, Central-West region of Brazil. The main outcome variables were calf circumference (CC; cm) and the APMT (mm). A receiver operating characteristic curve was built to assess the accuracy of APMT having CC as a golden pattern for sarcopenia. The best cutoff point was defined by Youden's J statistic. RESULTS The area under curve of APMT was 0.70 (95% confidence interval [CI], 0.63-0.76; P < 0.001) for all individuals, 0.74 (95% CI, 0.67-0.81; P < 0.001) for women, and 0.71 (95% CI, 0.58-0.85; P =.01) for men. The best cutoff point defined by Youden's J statistic was 17.63 mm for all individuals, the same for women. and 18.51 mm for men. CONCLUSION The APMT can be used for the diagnosis of sarcopenia. The optimal cutoff points for APMT are 17.63 mm for women and 18.51 mm for men in elderly communities in the Central-West Region of Brazil.

Abstract
OBJECTIVE To investigate the prevalence of hypophosphatemia as a marker of refeeding syndrome (RFS) before and after the start of nutritional therapy (NT) in critically ill patients. METHODS Retrospective cohort study including 917 adult patients admitted at the intensive care unit (ICU) of a tertiary hospital in Cuiabá-MT/Brasil. We assessed the frequency of hypophosphatemia (phosphorus <2.5mg/dl) as a risk marker for RFS. Serum phosphorus levels were measured and compared at admission (P1) and after the start of NT (P2). RESULTS We observed a significant increase (36.3%) of hypophosphatemia and, consequently, a greater risk of RFS from P1 to P2 (25.6 vs 34.9%; p<0.001). After the start of NT, malnourished patients had a greater fall of serum phosphorus. Patients receiving NT had an approximately 1.5 times greater risk of developing RFS (OR= 1.44 95%CI 1.10-1,89; p= 0.01) when compared to those who received an oral diet. Parenteral nutrition was more associated with hypophosphatemia than either enteral nutrition (p=0,001) or parenteral nutrition supplemented with enteral nutrition (p=0,002). CONCLUSION The frequency of critically ill patients with hypophosphatemia and at risk for RFS on admission is high and this risk increases after the start of NT, especially in malnourished patients and those receiving parenteral nutrition.

Abstract
OBJECTIVE To investigate the metabolic/inflammatory impact of reducing the preoperative fasting time in preschool children. METHODS Forty children were randomly assigned to a fasting group (absolute fasting after 00:00) and a carbohydrate (CHO) group (allowed to ingest, two hours before surgery, a carbohydrate-rich beverage). Blood samples were collected right before and after surgery to quantify the levels of albumin, interleukin-6, glucose, insulin, C-reactive protein and to calculate insulin resistance by the HOMA-IR index. RESULTS Preoperative fasting time in the CHO group were shorter than in the fasting group (2.49h vs. 11.24h, p <0.001). Pre- and post-surgical CRP levels were significantly lower in the CHO group (p = 0.05 and p = 0.02, respectively). The preoperative CRP/albumin ratios in the CHO group were lower than in the fasting group (p = 0.03). Four patients (21%) in the fasting group but none in the CHO group were hyperglycemic before surgery (p = 0.04). The two groups had similar levels of albumin, interleukin-6, insulin and HOMA index. There were no adverse events. CONCLUSION Reducing the preoperative fasting time with carbohydrate-rich beverages improves the perioperative metabolic and inflammatory responses of preschool children undergoing inguinal hernia surgery.

FACTORS RELATED TO THE REDUCTION OF THE RISK OF COMPLICATIONS IN COLORECTAL SURGERY WITHIN PERIOPERATIVE CARE RECOMMENDED BY THE ACERTO PROTOCOL. ACTA ACUST UNITED AC 2019; 32:e1477. [PMID: 31859930 PMCID: PMC6918738 DOI: 10.1590/0102-672020190001e1477] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Accepted: 09/03/2019] [Indexed: 12/11/2022]
Abstract
Background: Perioperative care multimodal protocol significantly improve outcome in surgery. Aim: To investigate risk factors to various endpoints in patients submitted to elective colorectal operations under the ACERTO protocol. Methods: Cohort study analyzing through a logistic regression model able to assess independent risk factors for morbidity and mortality, patients submitted to elective open colon and/or rectum resection and primary anastomosis who were either exposed or non-exposed to demographic, clinical, and ACERTO interventions. Results: Two hundred thirty four patients were analyzed and submitted to 156 (66.7%) rectal and 78 (33.3%) colonic procedures. The length of hospital postoperative stay (LOS) ≥ 7 days was related to rectal surgery and high NNIS risk index; preoperative fasting ≤4 h (OR=0.250; CI95=0.114-0.551) and intravenous volume of crystalloid infused > 30ml/kg/day (OR=0.290; CI95=0.119-0.706). The risk of postoperative site infection (SSI) was approximately four times greater in malnourished; eight in rectal surgery and four in high NNIS index. The duration of preoperative fasting ≤4 h was a protective factor by reducing by 81.3% the risk of surgical site infection (SSI). An increased risk for anastomotic fistula was found in malnutrition, rectal surgery and high NNIS index. Conversely, preoperative fasting ≤4 h (OR=0.11; CI95=0.05-0.25; p<0.0001) decreased the risk of fistula. Factors associated with pneumonia-atelectasis were cancer and rectal surgery, while preoperative fasting ≤ 4 h (OR=0.10; CI95=0.04-0.24; p<0.0001) and intravenous crystalloid ≤ 30 ml/kg/day (OR=0.36; CI95=0.13-0.97, p=0.044) shown to decrease the risk. Mortality was lower with preoperative fasting ≤4 h and intravenous crystalloids infused ≤30 ml/kg/day. Conclusion: This study allows to conclude that rectal procedures, high NNIS index, preoperative fasting higher than 4 h and intravenous fluids greater than 30 ml/kg/day during the first 48 h after surgery are independent risk factors for: 1) prolonged LOS; 2) surgical site infection and anastomotic fistula associated with malnutrition; 3) postoperative pneumonia-atelectasis; and 4) postoperative mortality.

Abstract
OBJECTIVE To evaluate the effects of intravenous infusion of fluids and sodium on the first day of admission on infusion of enteral nutrition in the first 5 days in intensive care patients. METHODS A prospective cohort study was conducted with critical nonsurgical patients admitted for at least 5 days who were on mechanical ventilation and receiving enteral nutrition. The amount of intravenous fluids and sodium infused on the first day and the volume of enteral nutrition infused in the first 5 days were investigated. The volume of intravenous fluids > 35mL/kg or ≤ 35mL/kg of body weight and sodium (above or below the 25th percentile) infused on the first day was compared with infused enteral nutrition. RESULTS A total of 86 patients were studied, with a mean (± standard deviation) of 65 ± 17 years, of which 54.7% were female. On the first day, 3,393.7 ± 1,417.0mL of fluid (48.2 ± 23.0mL/kg) and 12.2 ± 5.1g of sodium were administered. Fifty-eight (67.4%) patients received more than 35mL/kg of fluids. In 5 days, 67 ± 19.8% (2,993.8 ± 1,324.4mL) of the prescribed enteral nutrition was received. Patients who received > 35mL/kg of intravenous fluids also received less enteral nutrition in 5 days (2,781.4 ± 1,337.9 versus 3,433.6 ± 1,202.2mL; p = 0.03) versus those who received ≤ 35mL/kg. Patients with intravenous sodium infusion above the 25th percentile (≥ 8.73g) on the first day received less enteral nutrition volume in 5 days (2,827.2 ± 1,398.0 versus 3,509.3 ± 911.9mL; p = 0.02). CONCLUSION The results of this study support the assumption that the administration of intravenous fluids > 35mL/kg and sodium ≥ 8.73g on the first day of hospitalization may contribute to the lower infusion of enteral nutrition in critically ill patients.

Abstract
Objective: To investigate the effects of overnight fasting on handgrip strength of adult inpatients. Methods: A prospective clinical study enrolling 221 adult patients. The endpoints were handgrip strength obtained by dynamometry in three time points (morning after an overnight fasting, after breakfast and after lunch) and the cumulative handgrip strength (mean of handgrip strength after breakfast and lunch) in the same day. The mean of three handgrip strength measures was considered to represent each time point. A cut-off for the mean overnight fasting handgrip strength at the 50th percentile (35.5kg for males and 27.7kg for females) was used for comparisons. We registered the age, sex, current and usual weight (kg), weight loss (kg), diagnosis of cancer, nutritional status, elderly frequency, digestive tract symptoms, type of oral diet, and the amount of dinner ingested the night before handgrip strength (zero intake, until 50%, <100% and 100%). Results: Handgrip strength evaluated after an overnight fasting (31.2±8.7kg) was lesser when compared with handgrip strength after breakfast (31.6±8.8kg; p=0.01), and with cumulative handgrip strength (31.7±8.8kg; p<0.001). Handgrip strength was greater in patients who ingested 100% (33.2±9.1kg versus 30.4±8.4kg; p=0.03) and above 50% of dinner (32.1±8.4kg versus 28.6±8.8kg; p=0.006). Multivariate analysis showed that ingesting below 50% of dinner, severe malnutrition, and elderly were independent factors for handgrip strength reduction after overnight fasting. Conclusion: The muscular function was impaired after an overnight fasting of adult patients hospitalized for medical treatment, especially for those with low ingestion, malnourished and elderly.

Abstract
ABSTRACT Objective: to present recommendations based on the ACERTO Project (Acceleration of Total Post-Operative Recovery) and supported by evidence related to perioperative nutritional care in General Surgery elective procedures. Methods: review of relevant literature from 2006 to 2016, based on a search conducted in the main databases, with the purpose of answering guiding questions previously formulated by specialists, within each theme of this guideline. We preferably used randomized controlled trials, systematic reviews and meta-analyzes but also selected some cohort studies. We contextualized each recommendation-guiding question to determine the quality of the evidence and the strength of this recommendation (GRADE). This material was sent to authors using an open online questionnaire. After receiving the answers, we formalized the consensus for each recommendation of this guideline. Results: the level of evidence and the degree of recommendation for each item is presented in text form, followed by a summary of the evidence found. Conclusion: this guideline reflects the recommendations of the group of specialists of the Brazilian College of Surgeons, the Brazilian Society of Parenteral and Enteral Nutrition and the ACERTO Project for nutritional interventions in the perioperative period of Elective General Surgery. The prescription of these recommendations can accelerate the postoperative recovery of patients submitted to elective general surgery, with decrease in morbidity, length of stay and rehospitalization, and consequently, of costs.

Abstract
OBJECTIVE To investigate whether the abbreviation of preoperative fasting with a drink containing glutamine and dextrinomaltose improves organic response to surgical trauma. METHODS Thirty-six female patients adult (18-62 years) candidates for elective laparoscopic cholecystectomy were randomly divided into three groups: conventional fasting (fasting group), and two groups receiving two different diets, eight hours (400ml) and two hours before induction of anesthesia (200ml): carbohydrate (CHO) group (12.5% dextrinomaltose) and the glutamine (GLN) group (12.5% dextrinomaltose and 40 and 10g of glutamine, respectively). Blood samples were collected pre and postoperatively. RESULTS Twenty-eight patients completed the study. No pulmonary complication occurred. Gastric residual volume was similar between groups (p = 0.95). Postoperatively, all patients from the fasting group had abnormal glucose (> 110mg/dl), this abnormality being of 50% when compared to the CHO group (p = 0.14), and of 22.2% when compared to the GLN group (p = 0.01). All patients who had the fasting period shortened (CHO + GLN) had normal postoperative insulin, contrasting with 66.7% in the fasted group (p = 0.02). The abnormal sensitivity to insulin postoperatively rose from 32.1% to 46.4% of cases (p = 0.24), and it occurred in only 11.1% of patients in GLN group when compared to 55.5% in the fasting group (p = 0.02). CONCLUSION the abbreviation of preoperative fasting for two hours with dextrinomaltose and glutamine improves insulin sensitivity in patients undergoing elective laparoscopic cholecystectomy.

Abstract
OBJETIVO: Correlacionar a incidência de úlcera por pressão com o estado nutricional e a capacidade funcional de pacientes internados. MÉTODOS: Estudo de corte transversal realizado em dois hospitais, totalizando 130 pacientes (idade mediana = 52 (14-85) anos, 77 (59,2%) homens e 53 (40,8%) mulheres), sendo 72 (55,4%) internados para tratamento clínico, 40 (30,8%) para tratamento cirúrgico e 18 (13,8%) em terapia intensiva. Os pacientes foram avaliados pela avaliação subjetiva global e classificados, de acordo com sua capacidade funcional, em acamados e não acamados. Registrou-se a presença e número de úlceras, e sua gravidade. A classificação das úlceras foi estabelecida como grave, para lesões de 3º e 4º graus, e leve, para os graus 1 e 2. RESULTADOS: A incidência de úlcera por pressão na população estudada foi de 19,2% (n=25). Não houve associação significativa com o sexo, a idade e tipo de tratamento do paciente. Os pacientes acamados apresentaram 7,5 vezes mais chance de apresentar úlceras (19/50; 38,0%) do que os que deambulavam (6/80; 7,5%; OR=7,5; IC95%: 2,7-20,7; p<0,001). A incidência de úlcera nos pacientes gravemente desnutridos (20/49; 40,8%) foi 10 vezes maior que nos pacientes considerados não gravemente desnutridos (5/81; 6,1%; OR=10,4 IC95%: 3,6-30,5; p<0,0001) Pela análise multivariada, tanto a capacidade funcional (acamado, OR=9,2; IC95%: 2,8-30,1; p<0,001) quanto o estado nutricional (desnutrido grave, OR=3,8; IC95%: 1,0-13,9; p=0,04) associaram-se com a úlcera por pressão. CONCLUSÃO: A incidência de úlcera por pressão está diretamente correlacionada com a desnutrição e com a restrição ao leito dos pacientes internados.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of an early enteral formula containing whey protein, in comparison to a standard enteral formula containing casein as the protein source, on the levels of glutathione and inflammatory markers in aged patients with acute ischemic stroke. METHODS Thirty-one elderly patients (12 males and 19 females; median age = 74 [range,65-90] y old) with ischemic stroke were randomized to receive early nasogastric feeding (35 kcal/kg/d and 1.2 g of protein/kg/d) with either a formula containing polymeric [corrected] casein (casein group, n =16) or another isocaloric and isonitrogenous formula containing hydrolyzed whey protein (WP group, n = 15) for 5 d. The primary endpoints of the study were the changes in the serum levels of glutathione peroxidase, C-reactive protein (CRP), and interleukin 6 (IL-6). RESULTS Twenty-five patients completed the study (10 in the WP group and 15 in the casein group). Mortality was similar between groups (33%; P = 1.00) and was associated with higher serum IL-6 (73.7 ± 24.7 versus 16.6 ± 2.4 pg/dL; P = 0.04) and CRP (82.0 ± 35.6 versus 48.3 ± 14.5 mg/L; P = 0.02) levels. Albumin levels dropped from the first to the fifth feeding day only in the casein group (P < 0.01). Serum IL-6 decreased (62.7 ± 47.2 to 20.6 ± 10.3 pg/dL; P = 0.02) and glutathione increased (32.2 ± 2.1 to 39.9 ± 6.8 U/G Hb; P = 0.03) only in the WP group. Serum IL-6 was lower (P = 0.03) and glutathione was higher (P = 0.03) in whey protein-fed patients than in the casein group. CONCLUSION Enteral formula containing whey protein may decrease inflammation and increase antioxidant defenses in elderly patients with ischemic stroke, compared to casein-containing formula.

Abstract
OBJECTIVE Investigate whether the right adductor pollicis muscle thickness is a reliable method to evaluate the nutritional status of surgical patients and whether it correlates or not correlate to other anthropometric, biochemical, and clinical parameters. METHODS Cross-sectional study evaluating 87 patients candidates to major operations of the gastrointestinal tract. All were submitted to global subjective evaluation, traditional anthropometry (arm circumpherence ; triceps skin fold; and arm muscle circumpherence, serum albumin, lymphocytes and measurement of in both hands. RESULTS The mean right adductor pollicis muscle thickness in dominant hand was 12,64 +/- 3,19 mm and in non-dominant hand (EMAPND) 12,23 +/- 2,9 mm. Sensitivity was 72,37% for left adductor pollicis muscle and 77,33% for left adductor pollicis muscle thickness being the cut-offs given by the ROC curve (13,4 and 13,1mm respectively). Specificity was 100% for both hands. There was a significantly correlation (P<0.01) for right adductor pollicis muscle thickness with all anthropometric parameters. The mean value for normal individuals was significantly greater (P<0.001) than for mild malnourished which was greater (p<0.05) when compared to patients with severe malnutrition. CONCLUSION right adductor pollicis muscle thickness is a low-cost, reliable, and trustworthy method to assess nutritional status that can be easily and safety used in clinical practice for surgical patients.

Abstract
Preoperative fasting is mandatory before anesthesia to reduce the risk of aspiration. However, the prescribed 6-8 h of fasting is usually prolonged to 12-16 h for various reasons. Prolonged fasting triggers a metabolic response that precipitates gluconeogenesis and increases the organic response to trauma. Various randomized trials and meta-analyses have consistently shown that is safe to reduce the preoperative fasting time with a carbohydrate-rich drink up to 2 h before surgery. Benefits related to this shorter preoperative fasting include the reduction of postoperative gastrointestinal discomfort and insulin resistance. New formulas containing amino acids such as glutamine and other peptides are being studied and are promising candidates to be used to reduce preoperative fasting time.

Abstract
PURPOSE To investigate the effects of the addition of probiotic bacteria to a hydrolyzed diet on the recovery of goblet cells during renutrition in an animal model of malnutrition. METHODS Twenty-six male Wistar rats (200-250g) were included in the study. Six were kept under normal conditions (sham group) while twenty received an aproteic diet for 15 days, and were randomized thereafter to receive a hydrolyzed diet containing (n=6; probiotic group) or not (n=6; hydrolyzed group) probiotics (10(6) cfu/g of Streptococcus thermophilus e Lactobacillus helveticus); or immediately killed (n=8; aproteic group). Histological slides containing cecal and sigmoid biopsies were used to counting the number of goblet cells and the goblet cells/colonocytes ratio. RESULTS Malnutrition diminished the population of goblet cells in all sites. Goblet cells/colonocytes ratio of the probiotic group was significantly greater than hydrolyzed group at the ceccum (0.39 +/- 0.03 vs. 0.34 +/-0.02; p=0.02). Only rats fed with probiotics showed complete restoration of the normal goblet cells/colonocytes ratio at the sigmoid (0.37 +/- 0,02 vs. 0.22 +/- 0,03; p<0,001). CONCLUSION Streptococcus thermophilus and Lactobacillus helveticus added to a renutrition diet enhance the recovery of mucosal atrophy induced by malnutrition and especially induce a rapid restoration of goblet cells population in the malnourished colonic mucosa.

Abstract
PURPOSE The aim of this study was to investigate the effect of enemas containing probiotics and budesonide on the systemic inflammatory response in experimental colitis. METHODS Fifty male Wistar rats with experimental colitis induced by 10% acetic acid enema were randomized to five groups (10 rats each) according to the treatment: group 1--saline solution, group 2--budesonide (0.75 mg/kg/day), group 3--probiotics (1mg/day), group 4--probiotics plus budesonide, and group 5--control, with not-treated rats. The following variables were studied: body weight, serum levels of albumin, C-reactive protein and interleucine-6 (IL-6). RESULTS All animals lost weight between the beginning and the end of the experiment (280+ 16 mg versus 249+21 mg, p< 0.001). There was a significant decrease in the serum albumin between the normal pre-induction level (3.45 + 0.49 mg/dL) and the 1st day after colitis induction (1.61+051 mg/dL, p< 0.001) in all treated groups when compared to the control group. C- reactive protein increased after induction and diminished on the 7th day in all groups. In the control group there was an increase in the IL-6 after colitis induction. None of the treated groups significantly differed from IL-6 pre-colitis status (p>0.05). Only probiotic rats presented a significant decrease of IL-6 than controls (0,30+/-0,08 mg/dL vs. 0,19+/-0,03 mg/dL; p<0.01). CONCLUSION Probiotics are effective to diminished inflammatory status mediated by IL-6 in experimental colitis.

Abstract
PURPOSE To investigate the effects of perioperative administration of diet containing probiotics on the immune response, anastomotic resistance, and colonic mucosal trophism in rats underwent left-sided colonic anastomosis. METHODS Sixty adults Wistar rats were randomized to two groups (A and B) with 30 animals each to receive or not a diet supplemented with probiotics (Streptococcus thermophilus e Lactobacillus helveticus) during pre- and postoperative period. They underwent laparotomy followed by left colon section and immediate anastomosis. Groups of 15 animals were killed either on the 4th (groups A1 and B1) or 7th PO (groups A2 and B2) days. The outcome variables were serum proteins, albumin, globulins and IgA, length and weight of the colon, mucosal weight, DNA content and anastomotic bursting pressure. RESULTS Colonic weight was greater in probiotic group compared to controls (1.69+/-0.34 g vs 1.48+/-0.26 g; p<0.05). Total serum proteins and globulin were higher in probiotic animals (proteins = 7.05+/-0.97 g/dl vs 6.57+/-0.66 g/dl e globulins = 5.1+/-0.62 g/dl vs 4.68+/-1.1 g/dl; p<0.05). Serum IgA increased from basal to post-operative days only in the probiotic group (p<0.01). CONCLUSIONS Perioperative probiotics enhanced the immune response and colonic weight. Probiotics failed to increase anastomotic resistance.

Abstract
RACIONAL: Estudos recentes mostram que a abreviação do jejum pré-operatório, ao contrário do jejum de 6-8 h apresenta vários benefícios. Pacientes que recebem carboidratos apresentam menos fome e menos ansiedade do que os que permaneceram em jejum noturno. A ingestão pré-operatória de carboidratos por via oral no dia da operação diminui a resposta orgânica ao trauma. OBJETIVO: Avaliar o efeito da ingestão de bebida com carboidratos 6 e 2 horas antes da operação na ocorrência de sintomas gastrointestinais pós-operatórios em pacientes colecistectomizadas. MÉTODOS: Estudo prospectivo e randomizado com 54 pacientes do sexo feminino (42[19-69] anos) candidatas à colecistectomia eletiva foram randomizadas para receber uma bebida contendo 12.5% de carboidratos, 6 (400 mL) e 2 horas (200 mL) antes da operação (grupo carboidrato n = 28) ou jejum de 6-8 horas (grupo convencional n= 26). As variáveis investigadas foram a ocorrência de vômitos, náuseas, distensão abdominal, eliminação de flatos e fezes, e o tempo de internação no pós-operatório. RESULTADOS: A ocorrência de distensão abdominal (42.3% vs 17.8%; P = 0,04), vômitos (53.8% vs 21.4%; P = 0,01) a associação de dois ou mais sintomas gastrointestinais (73.1% vs 39.3%; P = 0,01) e o tempo de internação pós-operatória (2 [1-3] vs 1 [1-3] dias; P = 0,04) foram significativamente menores no grupo carboidrato. CONCLUSÃO: A ingestão carboidratos no pré-operatório diminui a ocorrência de manifestações gastrointestinais pós-operatórias e o tempo de internação em colecistectomia.
