RESUMO
Objective:To evaluate the nutritional status of patients in intensive care unit (ICU) by using nutritional risk screening 2002 scale (NRS2002), subjective general assessment (SGA) and critical illness nutritional risk score (NUTRIC), and to compare the characteristics and applicability of three scoring tools.Methods:A cross-sectional survey was conducted. 315 patients admitted to the comprehensive ICU of Affiliated Qingdao Municipal Hospital of Qingdao University from April 2018 to July 2019 were enrolled. Basic information of patients was collected, and patients were divided into two groups with 65 years old as the standard to compare the nutritional status of patients among different genders and ages. The nutritional status of patients were assessed by NRS2002, SGA, and NUTRIC. Height, weight, body mass index (BMI), triceps skinfold thickness (TSF), upper arm circumference (AC), leg circumference (LC), and other related parameters of human nutrition were measured. Total protein (TP), albumin (Alb), prealbumin (PA), serum creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), triglyceride (TG), total number of lymphocytes (LYM), hemoglobin (Hb), C-reactive protein (CRP) and other blood biochemical indicators were performed. Spearman rank correlation analysis was used to analyze the correlation between the three nutrition evaluation scales and other objective nutrition parameters. Binary multivariate Logistic regression analysis was used to evaluate the influencing factors of nutritional status with three scales of patients in ICU.Results:Among 315 patients in ICU, 183 were male and 132 were female. There were 143 patients < 65 years old and 172 ≥ 65 years old. In male patients, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, age and BUN of patients aged ≥ 65 years old were significantly increased, and the height, weight, BMI, TSF, AC, LC, Alb and PA were significantly lowered as compared with those aged < 65 years old, while the difference in other indicators was not statistically significant. In the female patients, the APACHEⅡ score, age, SCr and BUN of the patients aged ≥ 65 years old were significantly increased, the height, Alb, PA and Hb were significantly decreased as compared with those aged < 65 years old, and the difference in other indicators was not statistically significant. The proportion of patients with nutritional risk evaluated by NRS2002 (NRS2002 score ≥ 3) was 87.62% (276/315). SGA showed that the proportion of malnourished patients (SGA was grade B or C) was 62.86% (198/315). NUTRIC showed 66.03% of patients (208/315) in high nutritional risk (NUTRIC score ≥ 5). Spearman rank correlation analysis showed that there were significant correlations among NRS2002, SGA and NUTRIC of patients in ICU ( rNRS2002 with SGA = 0.522, rNRS2002 with NUTRIC = 0.392, rSGA with NUTRIC = 0.442, all P < 0.01). Among the three assessment tools, SGA had the best correlation with blood biochemical indicators and body measurements to assess nutritional status, followed by NRS2002, and NUTRIC had the worst correlation. Binary multivariate Logistic regression showed that APACHEⅡ score, BMI, AC, BUN and TG were factors influencing NRS2002 assessment of nutritional status in ICU patients [odds ratio ( OR) were 2.535, 0.404, 1.438, 0.858, and 2.391, respectively, all P < 0.05]; APACHEⅡ score, age, weight, TP, BUN, LYM and CRP were influence factors of SGA for evaluating the malnutrition of patients in ICU ( OR values were 1.074, 1.038, 0.921, 0.947, 1.077, 1.625 and 0.991, respectively, all P < 0.05); APACHEⅡ score, age, LYM and CRP were the influence factors of NUTRIC assessment for malnutrition of patients in ICU ( OR values were 1.159, 1.049, 0.715 and 0.995, respectively, all P < 0.05). Conclusions:The nutrition status of ICU patients evaluated by NRS2002, SGA and NUTRIC was simple and easy to operate, and the positive screening rate of NRS2002 was the highest, which was suitable for patients with mild conditions in ICU. SGA is the most valuable tool to evaluate the nutritional status of ICU patients. NUTRIC has a poor correlation with objective indicators reflecting nutritional status, while its indicators are objective and easy to obtain, which is suitable for ICU patients with critical condition and unclear consciousness. Nutritional assessment tools should be integrated with the patient's gender, age, anthropometric and biochemical indicators.
RESUMO
Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in middle-aged and older adult population in Shanghai Pudong New District.Methods Two thousand residents aged 45 years and above were randomly selected for questionnaire survey and health check-up in Shanghai Pudong New District from July 2006 to October 2010.The laboratory examinations were also performed including the urine routine,urinary protein to creatinine ratio,serum creatinine,blood glucose and lipids.The glomerular filtration rate (eGFR) was estimated by simplified Chinese MDRD (modification of Diet in Renal Disease) equation.SPSS 13.0 statistical software was used for statistical analysis.Results Among 1905 residents who completed survey and examinations,the adjusted prevalence of albuminuria was 12.0％ (95％ CI:0.105-0.135) and of eGFR less than 60 ml · min-1 · 1.73 m-2 was 1.9％ (95 ％ CI: 0.172-0.213).The prevalence of CKD was 12.6％ (95 ％ CI: 0.112-0.142).Logistic regression analysis revealed that age (OR =1.043),hypertension (OR =2.272),diabetes mellitus (OR =1.233)and hyperuricemia (OR =1.003)were independently associated with CKD.Conclusions The prevalence of CKD in adult residents (≥45 years) from Shanghai Pudong New District is high.It is necessary to carry out early screening and to intervene risk factors of CKD in middle-aged and older residents.
RESUMO
OBJECTIVE: To analyze the effects of Astragalous Injection on oxidative stress and micro-inflammatory status in patients undergoing maintenance hemodialysis (MHD). METHODS: Sixty MHD patients were included and randomized into treatment group and control group, with another 10 healthy volunteers as normal control. The patients in the treatment group were treated with Astragalous Injection and the patients in the control group were treated with normal saline for 12 weeks. A spectrophotometric method was used for the measurement of plasma concentrations of oxidative parameters including advanced glycation end products (AGEs), advanced oxidation protein product (AOPP), malondialdehyde (MDA) and vitamin E (Vit E). The content of C-reactive protein (CRP) was evaluated by enzyme-linked immunosorbent assay. RESULTS: Compared with the normal control group, the plasma levels of AGEs, AOPP, MDA and CRP were significantly increased, while plasma level of Vit E was significantly decreased in MHD patients ( P<0.01). After Astragalous Injection treatment, the plasma levels of AGEs, AOPP, MDA and CRP were decreased as compared with the control group ( P<0.01), while there was no significant difference in plasma Vit E level between the treatment group and control group. CONCLUSION: There exist oxidative stress and micro-inflammation in MHD patients. Astragalous Injection can ameliorate the accumulation of oxidative products and micro-inflammatory status, but it has no significant effect on plasma Vit E level.
