001). The median defecation frequency per week increased significantly (2 to 7 for flaxseed and 2 to 6 for lactulose, p less then 0.001 for both groups). The Patient Assessment of Constipation Quality of Life score decreased significantly (-1.34 and -0.66 for flaxseed and lactulose, respectively; p less then 0.001 for both groups). CONCLUSIONS Flaxseed flour is somewhat more effective at increasing defecation frequency than lactulose, improving bowel movements and promoting life quality of subjects with chronic functional constipation in the Chinese population.BACKGROUND AND OBJECTIVES The severity of neurologic impairment is significantly associated with gastrointestinal (GI) hemorrhage. Therefore, the aim of this study was to compare the effect of two nutritional interventions in acute ischemic stroke patients with GI hemorrhage. METHODS AND STUDY DESIGN We retrospectively studied consecutive ischemic stroke patients with GI hemorrhage from January 2014 to December 2018. They were stratified into two programs of nutritional therapy after GI hemorrhage moderate feeding (more than 70% optimal caloric uptake, 50-100 mL/h) and trophic feeding (16-25% of the target energy expenditure, 25 kcal/kg per day, 10- 30 mL/h) with supplemental parenteral nutrition. this website RESULTS The group receiving moderate feeding included 30 patients, and the group receiving trophic feeding and supplemental parenteral nutrition included 32 patients. There was no statistically significant difference between the two groups in the baseline characteristics of the patients. Mortality, Glasgow Coma Scalith lower mortality, higher GCS score at discharge, and higher GOS score 3 months after discharge.BACKGROUND AND OBJECTIVES We performed this study to evaluate serum iron and ferritin concentrations, serum total iron-binding capacity (TIBC), and proportion of overall iron deficiency among patients with non-dialysisdependent chronic kidney disease (ND-CKD). METHODS AND STUDY DESIGN A hospital-based cross-sectional observational study was conducted on 175 adult patients with stage 3-5 chronic kidney disease (CKD) by using 51 healthy age-sex-matched Vietnamese adults as the control group. We next examined the prevalence of anemia and determined the serum iron and ferritin concentrations and TIBC. Anemia in CKD was defined as hemoglobin levels 100 ng/mL and TSAT less then 20%, and absolute iron deficiency was defined as serum ferritin less then 100 ng/mL and TSAT less then 20%. Overall iron deficiency was defined as the presence of either absolute or functional iron deficiency. RESULTS Anemia prevalence in our study was approximately 88.6% with a mean hemoglobin concentration of 9.71±2.26 g/dL. The median serum TIBC was lower in the CKD group (50.4 μmol/L) than in the control group (66.0 μmol/L; p less then 0.001). The proportion of overall iron deficiency was 44.0%. TIBC had a diagnostic value for overall iron deficiency (area under the ROC curve=0.81; p less then 0.001). CONCLUSIONS Anemia and iron deficiency are common in Vietnamese patients with NDCKD. TIBC had diagnostic value for overall iron deficiency.BACKGROUND AND OBJECTIVES This study aimed to assess the influence of prolonged preoperative fasting on prognosis in elective surgery. METHODS AND STUDY DESIGN A retrospective, controlled study involving patients admitted to our surgical intensive care unit who underwent a gastrointestinal operation under general anesthesia. Patients were divided into regular preoperative fasting time (n=57) and prolonged preoperative fasting time (n=73) groups. Clinical data were collected including patients' demographics, intraoperative and postoperative operation time, volume of blood loss, intensive care unit stay, hospital stay, postoperative complications and other factors. RESULTS Patients in the regular preoperative fasting time group had less duration of mechanical ventilation support after surgery [245 (177, 450) min vs 315 (210, 812) min (p=0.021)] and the postoperative myocardial injuries (myocardial injury 2 cases vs 11 cases, p=0.038) and reoperation percentages (reoperation 0 cases vs 7 cases, p=0.044) were lower compared to the prolonged preoperative fasting time group. In addition, patients in the regular preoperative fasting time group presented with a significantly shorter period of postoperative fasting time [6.0 (5.0, 8.0) vs 8.0 (6.0, 13.0), p=0.005]. CONCLUSIONS Prolonged preoperative fasting time led to unfavorable outcomes after gastrointestinal operations. Thus, reducing preoperative fasting time is likely to accelerate postoperative recovery in gastrointestinal surgery patients.BACKGROUND AND OBJECTIVES Acute acalculous cholecystitis (AAC) often occurs in critically ill patients, especially in those that have experienced trauma, surgery, shock, and prolonged fasting. Early enteral nutrition has been shown to significantly reduce morbidity and mortality compared to other nutritional support strategies. The purpose of this study was to evaluate the effect of early enteral nutrition on the incidence of AAC among trauma patients. METHODS AND STUDY DESIGN Multi-strategy nutritional protocol was implemented in the intensive care unit (ICU) in 2016 for early enteral nutrition and proper nutritional support. The traumatized critically-ill patients without volitional intake who were admitted to ICU between 2015 and 2017 were included. Basic characteristics, duration of fasting, and the incidence of percutaneous cholecystostomy (PC) due to AAC were analyzed according to the year. RESULTS Enteral nutrition was indicated in 552 trauma patients (28.2%). The mean duration of fasting was shortened from 6.5 days in 2015 to 5.4 days in 2017 (p=0.202). The incidence of PC was significantly decreased from 2015 to 2017 [6/171 (3.5%) vs. 6/204 (2.9%) vs. 0/177 (0%), p=0.023]. The provision of central parenteral nutrition (p=0.001) and fasting over 7 days (p=0.014) proved to be a risk factor of AAC. CONCLUSIONS This study showed that the incidence of PC due to AAC was decreased significantly after the implementation of a nutritional protocol among traumatized critically ill patients. Early enteral nutrition may be effective in reducing the AAC among trauma patients who are at high risk of AAC.
