Experienc of nurtitional treatment to 7 patients with acute renal failure (ARF) and nitrogemia after biliarty (tract) surgery is reported in this article. Nittrogen source inn all cases was obtained from "Renal Amine" and "7% Vamin" etc,which are composed of 8 essential amino acids (EAA), and the nergery sources are mainly supplyed by Intralipid (20 or 10%) and suitable amount of glucose. The nutritional admicture of "all in one" were employed as parenteral nutrition (PN). Satisfactary curative effecs in these patients were obtained. The suthors consider that (a) the nutritional treatment of different casuses of ARF should be providing enough energy and more EAA requirments than in normal need to synthesizw non-essential amino acide (NEAA) and protein from excessive blood urea nitrogen (BUN) for redcuing pritein breakdown and nitrogemia, and (b) 20% Intralipid is an effective low-volume, highly calories nutritional agent specially in ARF patients with restiction of waterr.
Objective To investigate the effect of mesenteric lymphatic duct liagtion and glutamine enteral nutrition on intestine and distant organs in intestinal ischemia/reperfusion injury. Methods Forty male SD rats undergoing gastrostomy were randomly assigned into 5 groups (n=8): sham operation group, normal enteral nutrition group, normal enteral nutrition+lymphatic duct ligation group, glutamine group and glutamine+lymphatic duct ligation group. Sham operation group only received laparotomy after 7 days of full diet, the other four groups were subjected to 60 min of intestinal ischemia after 7 days of enteral nutrition, and the two lymphatic duct ligation groups were plus mesenteric lymphatic duct ligation. The original nutrition continued 3 days after reperfusion. Intestinal permeability was detected on day 1 before reperfusion, day 1 and 3 after reperfusion. Intestinal morphology was observed, endotoxin, D-lactate and diamine oxidase levels in serum, and apoptotic index in lung tissue were detected on day 3 after reperfusion. Results The intestinal permeability in each group was significantly increased on day 1 after reperfusion (Plt;0.05), and which in normal enteral nutrition+lymphatic duct ligation group and glutamine+lymphatic duct ligation group were significantly decreased on day 3 after reperfusion (Plt;0.05). The mucosal thickness and villus height of ileum and mucosal thickness of jejunium in glutamine+lymphatic duct ligation group were significantly higher than those in other groups (Plt;0.05), and villus height of ileum in glutamine group was higher than that in normal enteral nutrition group (Plt;0.05); those morphology indexes in normal enteral nutrition+lymphatic duct ligation group were higher than those in normal enteral nutrition group, but there was no statistical signification (Pgt;0.05). Apoptosis index of lung tissue in lymphatic duct ligation groups was significant lower than that in no-ligation groups (Plt;0.05). Levels of endotoxin, D-lactate, and diamine oxidase in lymphatic duct ligation groups had downward trends compared with no-ligation groups, but there was no statistical signification (Pgt;0.05). Conclusions Intestinal ischemia/reperfusion injury of rats can cause intestinal permeability increase, bacterial endotoxin translocation and systemic inflammatory response. Mesenteric lymphatic duct ligation and glutamine enteral nutrition intervention can weak lung tissue damage, increase thickness of intestinal mucosa, maintain intestinal barrier function, reduce endotoxin translocation and attenuate systemic inflammatory response. Enteral nutrition with glutamine was better than normal enteral nutrition.
Objective To investigate the nutritional status of hospitalized patients with chronic kidney disease (CKD), analyze the influencing factors, and construct a predictive model to provide a localized theoretical basis and more convenient risk prediction indicators and models for clinical nutrition support and intervention treatment of CKD patients in China. Methods Convenience sampling was used to select hospitalized CKD patients from Department of Nephrology, West China Hospital, Sichuan University, from January to October 2019. General information questionnaires, the Nutritional Risk Screening 2002 scale, and the Huaxi Emotional-distress Index questionnaire were used for data collection. Single factor analyses and multiple logistic regression analysis were conducted to explore the risk factors for malnutrition in CKD hospitalized patients. A predictive model was established and evaluated using receiver operating characteristic (ROC) curve analysis and bootstrap resampling. Results A total of 1059 valid copies of questionnaires were collected out of 1118 distributed. Among the 1059 CKD hospitalized patients, 207 cases (19.5%) were identified as having nutritional risk. The multiple logistic regression analysis showed that CKD stage [odds ratio (OR)=1.874, 95% confidence interval (CI) (1.631, 2.152), P<0.001], age [OR=1.015, 95%CI (1.003, 1.028), P=0.018], and the Huaxi Emotional-distress Index [OR=1.024, 95%CI (1.002, 1.048), P=0.033] were independent risk factors for malnutrition in CKD hospitalized patients, while serum albumin [OR=0.880, 95%CI (0.854, 0.907), P<0.001] was an independent protective factor. The evaluation of the multiple logistic regression analysis predictive model showed a concordance index of 0.977, standard deviation of 0.021, and P<0.05. The area under the ROC curve was 0.977. Conclusions The prevalence of malnutrition is relatively high among CKD hospitalized patients. CKD stage, age, psychological status, and serum albumin are influencing factors for malnutrition in CKD hospitalized patients. The multiple logistic regression model based on the above indicators demonstrates good predictive performance and is expected to provide assistance for early nutritional intervention to improve the clinical outcomes and quality of life for CKD patients with malnutrition in China.
Methods Sixty-six postoperative patients with gastric cancer combined diabetes were divided into 3 groups according to the balanced principle. In the frist group (FD group), FD was the nutrition preparation for 21 patients. In the second group (fresubin group), fresubin and the ordinary insulin injection were the nutrition preparation for 21 patients. In the third group (TPN group), the nutrition preparation came from TPN and the ordinary insulin injection for 24 patients. FD, fresubin or TPN were given at 24 h after operation, the levels of blood glucose for empty stomach, after meal (enteral nutrition or TPN) and the common complications compared among 3 groups of postoperative patients. Results ① In FD group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition were stable with little fluctuation and no insulin was needed with 1 case of hyperglycemia (4.8%). In fresubin group and TPN group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition or TPN were unstable with big fluctuation, with 6 cases (28.6%) and 8 cases (33.3%) of hyperglycemia, 5 cases (23.8%) and 6 cases (25.0%) of hypoglycemia in fresubin group and TPN group, respectively. Compared with fresubin group and TPN group, the rate of pathoglycemia was lower in FD group, the difference had statistical significance separately (Plt;0.05); There was no significant difference between fresubin group and TPN group (Pgt;0.05). ② The rates of infection of incisional wound in FD group (4.8%) and fresubin group (23.8%) were lower than that of TPN group (33.3%), there was significant difference among 3 groups (Plt;0.05); The time of passage of gas by anus in FD group and fresubin group were shorter than that in TPN group (Plt;0.05); There was no significant difference between FD group and fresubin group (Pgt;0.05). There were no significant differences of the rates of abdominal distension or diarrhea among 3 groups (Pgt;0.05). Conclusion Regarding postoperative patients with gastric cancer combined diabetes, in the early time field test group of the nutrition preparation, FD is better than fresubin or TPN, which does not increase the risk of the blood glucose change and have few complications.
Objective To investigate the relationship between the level of prognostic nutritional index (PNI) and 28-day mortality in patients after cardiopulmonary resuscitation. Methods A total of 955 patients admitted to intensive care unit after cardiopulmonary resuscitation between 2008 and 2019 were selected from the MIMIC-IV database and grouped according to the optimal cut-off value of PNI for retrospective cohort analysis. Primary outcome was defined as 28-day all-cause mortality. After adjusting for confounding factors by propensity score matching, the outcomes between high PNI and low PNI groups were compared. PNI and Sequential Organ Failure Assessment (SOFA) score were incorporated into a Cox proportional risk model to construct a predictive model, and the predictive effect was assessed using the concordance index, the net reclassification index, and the integrated discriminant improvement. Results After propensity score matching, compared with the high PNI group, the low PNI group had lower 28-day survival (P<0.001), higher doses of vasoactive drugs used during intensive care unit stay (P<0.001), higher SOFA score (P<0.001) and higher Logistic Organ Dysfunction System score (P=0.002). The admission PNI and SOFA score had similar predictive effects on 28-day mortality, with the area under the receiver operating characteristic curve of 0.639 and 0.638, respectively. In addition, compared with SOFA score alone, PNI combined with SOFA score improved the predictive performance, with an area under the curve of 0.673, the concordance index increasing from 0.598 to 0.622, and the net reclassification index and the integrated discriminant improvement estimates of 0.144 (P<0.001) and 0.027 (P<0.001), respectively. Conclusions PNI can be used as a new predictor of all-cause death risk within 28 days after cardiopulmonary resuscitation. SOFA score combined with PNI can improve the prediction effect.
ObjectiveTo explore the diagnostic efficacy of Geriatric Nutritional Risk Index (GNRI) in malnutrition of elderly patients with chronic obstructive pulmonary disease (COPD) in outpatient department. MethodsOne hundred and five elderly outpatients with COPD were enrolled in the study, and their nutritional screening was carried out. The clinical and laboratory parameters of patients in the normal nutrition group (high GNRI group) and malnutrition group (low GNRI group) were compared, and the correlation analysis was conducted. The diagnostic efficacy of GNRI was evaluated based on the malnutrition universal screening tool (MUST). ResultsThe prevalence of malnutrition was high in COPD elderly outpatients. The prevalence of malnutrition in group D was 61.8%. There were significant differences between the two groups in body mass index, serum albumin, FEV1 percentage in the predicted value, 6-minute walk distance, and the number of acute exacerbations in the past year. GNRI was significantly related to the above parameters. The sensitivity, specificity and accuracy of GNRI were 81.8%, 83.6% and 82.9%, using MUST as the standard. ConclusionGNRI can be used for nutritional screening of COPD patients in elderly outpatients, which is simple, convenient and relatively accurate, and can be popularized in other medical institutions.
In order to investigater the effect of nutritional support on nutrients metabolism after liver resection,we researched into the hepatectomy and total parenteral nutrition model in rats.The features of the model were no fasting before surgery,10% glucose subcutaneous injection prior to operation avoiding of blood loss and shortening of the surgical process.The 7-day mortality was markedly decreased.Anesthetized with phenobarbital(25mg/kg) injection in combination of ether inhalation,the rats recovered quickly from anesthesia and developed almost no infection of the respiratory tract after hepatectomy.The rats were supplied parenterally energy of 573kJ/kg and a marked improvement in survival was achieved after liver resection.By applying dual preventive rotation equipment of protective spring and IN-Stopper,nutrient solution could be safely infused.
Sarcopenia is a syndrome associated with reduced strength, mass and function of skeletal muscles. Aging of gastric cancer patients, lack of nutritional intake, and pathological mechanisms of gastric cancer increase the likelihood of sarcopenia. Sarcopenia is associated with the development of gastric cancer and may be a risk factor for the formation of gastric cancer. Sarcopenia is closely related to the prognosis and treatment of gastric cancer. At present, the treatment of sarcopenia is still in the exploratory stage, and more research is needed to obtain better treatment plans and improve the quality of life of patients. This article reviews the research status of sarcopenia and gastric cancer in order to provide evidence for clinical research.
Objective To explore the current status of nutritional literacy in maintenance hemodialysis (MHD) patients and analyze its influencing factors. Methods MHD patients in Wenjiang Hemodialysis Center of West China Hospital, Sichuan University between January and April 2022 were selected by convenient sampling method. A questionnaire survey was conducted using the Nutrition Literacy Evaluation Scale for end-stage renal disease dialysis patients, and the current status and influencing factors of nutritional literacy in MHD patients were analyzed. Results A total of 214 patients were included, with an average nutritional literacy score of 19.14±5.78 for MHD patients. Among them, there were 60 cases (28.04%) of highly likely low nutritional literacy, 124 cases (57.94%) of moderate nutritional literacy, and 30 cases (14.02%) of highly likely high nutritional literacy. The correlation test results showed that hemoglobin, albumin, cholesterol, triglyceride, calcium, phosphorus, potassium, creatinine, estimated glomerular filtration rate, and nutritional literacy scores were not correlated. The results of multiple linear stepwise regression analysis showed that education level [non-standardized partial regression coefficient (b)=1.821, 95% confidence interval (CI) (1.143, 2.498), P<0.001], age [b=?2.460, 95%CI (?4.247, ?0.672), P=0.007], hypertensive kidney damage [b=2.233, 95%CI (0.428, 4.039), P=0.016] were all factors affecting the nutritional literacy of MHD patients. Conclusions In clinical work, more attention should be paid to MHD patients with low educational level, older age, and more primary diseases. And targeted interventions should be adopted to improve the level of nutritional literacy in order to improve the quality of life of MHD patients.
Objective To study glutamine (GLN) and cholecystokinin (CCK) effects on prevention of cholestasis in total parenteral nutrition (TPN). Methods White rabbits were choosed as TPN models, which were divided into four groups, group 1, TPN only (n＝10); Group 2, TPN plus GLN administration (n＝10); Group 3, TPN plus CCK (n＝10); Group 4, TPN plus GLN and CCK administration. Bile components were assayed and the structural change in gallbladder and liver were observed under light and election microspes at the forth and eighth week. Results Increasing of bilirubin and cholesterol was observed in the 1st and 2nd groups at the forth week, but increasing in the 3rd group was observed at the eighth week. The 4th group was normal. Changes of gallbladder and liver structure in 1st and 3rd group occured at the forth week. Changes of 2nd group occured at the eighth week. No structural change was found in the 4th group. Conclusion The test prove that cholestasis would occure during TPN and become serious with time prolonging. Integrity and function of gallbladder-wall tissue cell could be defended and sustained by applying GLN, but there is no direct preventing action. There is apparent cholecy stokinetic and cholagogic fundations by applying CCK. But CCK would lose its function if gallbladderwall was damaged. The test prove that TPN+GLN+CCK is the best way to prevent cholestasis during TPN.
