Correlation between nutritional status screening by MNA-SF and acute stroke-associated infections in older adults.

PURPOSE: This study aimed to explore the correlation between nutritional status screening using the MNA-SF and stroke-associated infections (SAI) in older adults. METHODS: A retrospective study of patients aged over 70 years with acute stroke was conducted. The patients were divided into normal nutritional status, malnutrition risk, and malnutrition groups depending on their baseline MNA-SF scores. The correlation between nutritional status and SAI was identified using multivariate logistic regression. The receiver operating characteristic (ROC) curve was used to demonstrate the predicted value of MNA-SF. RESULTS: 497 patients were included, 101 (20.32%) developed SAI. 32.29% of patients with malnutrition developed SAI, while 25.14% of those with malnutrition risk developed SAI. Malnutrition (aOR 4.58, 95% CI 2.34-8.96, p < 0.001) and risk of malnutrition (aOR 3.70, 95%CI 2.01-6.85, p < 0.001) were independent risk factors for SAI in older stroke patients. The area under the curve (AUC) value of MNA-SF was 0.713. CONCLUSION: MNA-SF is a simple and effective nutritional screening tool for predicting the occurrence of SAI in older patients with acute stroke.

The nutritional status evaluation of gastrointestinal carcinoma patients by mini-nutritional assessment / 肠外与肠内营养

Objective: To evaluate the nutritional status of gastrointestinal carcinoma patients by mini-nutritional assessment(MNA),and to compare the relationship with different tranditional evaluative methods. Methods: The nutritional state and the malnutritional incidence were analysed by MNA questionnaire in 496 gastrointestinal carcinoma patients,and the relationship among MNA score and anthropometric measurements and laboratory test was studied.Results: ①According to the scores of MNA, 16.94%(84/496) patients were of mal-nutrition and 42.54%(211/496) patients were at risk of malnutrition.② In terms of each single index,BMI,TSF,AC and AMC,the prevalence of malnutrition was 13.5%,21.9%,15.1% and 15.5% respectively.③According to laboratory test,including serum albumin,PA,TLC,the incidence of malnutrition was 14.9%,25.4% and 30.8%.④ There was a significant correlation between the MNA score and tranditional nutritional estimated markers.The correlation coefficients of MNA with BMI,ALB,AC,TSF,AMC and TLC were between 0.18 and 0.53(P

Nutritional assessment and intervene points for retired residents in a community / 肠外与肠内营养

Objectives:To assess the nutritional status of retired residents in a community by mininutritional assessment(MNA) combined with anthropometry. Methods:MNA questionnaire and anthropometric parameters including waistline,hipline,height,weight,body mass index(BMI),midarm circumference,triceps skinfold(TSF) and midarm muscle circumference were performed in 115 retired residents. Results:①24 (20.9%) residents had MNA scores less than 23.5,which meaned malnutrition or at risk of malnutrition.②According to each single index,namely waistline, waist hip ratio and BMI,incidence of obesity was 53.9%,61.7% and 65.2% respectively.③According to each single index,that is,midarm circumference,TSF and midarm muscle circumference,prevalence of moderate or severe malnutrition was 1.7%,19.1% and 2.2%respectively.④There lied a significant correlation between MNA score and several anthropometric parameters. Conclusions:①Both overnutrition and undernutrition can be manifested in retired home residents,for whom nutritional intervene should be enhanced.②MNA questionnaire can be well used in Chinese.
