Objective To investigate the value of Malnutrition Screening Tool (MST) in ventilated patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods A single center retrospective observational study was conducted. The AECOPD patients who needed mechanical ventilation, admitted to ICU from January 2015 to June 2016 were enrolled in the study. They were divided into two groups according to the MST score, ie. a high risk malnutrition group (MST score≥2) and a low risk malnutrition group (MST score<2). The principle factors were analyzed including ICU mortality, in-hospital mortality, duration of invasive mechanical ventilation (IMV), length of ICU stay, and ICU readmission rate within 48 hours. Meanwhile the patients’ demographic and laboratory data were analyzed. Results A total of 101 patients were enrolled with 77 cases in the high risk malnutrition group and 24 cases in the low risk malnutrition group. The gender (χ2=1.882, P=0.172), age (t=1.091, P=0.33) and APACHE Ⅱ score (t=1.475, P=0.16) were similar in two groups. The high risk malnutrition group had significantly lower BMI (t=2.887, P=0.004) and lymphocyte count (t=3.402, P<0.001) than the low risk malnutrition group. Hemoglobin (t=0.817, P=0.36), albumin (t=0.706, P=0.44), pre-albumin (t=1.782, P=0.08) and procalcitonin (t=1.296, P=0.17) were similar in two groups. The high risk malnutritiongroup had significantly longer IMV duration (χ2=2.181, P=0.035) and length of ICU stay (χ2=2.364, P=0.02) than the low risk malnutrition group. While the ICU mortality (χ2=0.212, P=0.645), in-hospital mortality (χ2=0.212, P=0.645) and ICU readmission rate within 48 hours (χ2=1.656, P=1.0) were similar in two groups. Conclusion MST is a valuable tool in ICU to evaluated the nutrition status of ventilated AECOPD patients, and MST≥2 indicates longer IMV duration and length of ICU stay.
ObjectiveTo collect the nutrition data in patients with chronic kidney disease (CKD) from stage 1 to 4 and provide the basis for further intervention by analyzing the specific problems of the patients. MethodsA total of 132 CKD patients from stage 1 to 4 were enrolled between December 2012 and December 2013. Nutritionists used inbodyS10ww as a body composition analyzer to test the patients. The data from inbodyS10ww and laboratory indexes were analyzed on marasmus, overweight and obesity, risk of malnutrition, malnutrition, anemia and hypoalbuminemia. ResultsThe percentage of marasmus in those CKD patients was 3.0%, overweight and obesity was 39.4%, the risk of malnutrition was 22.7%, malnutrition was 19.7%, anemia was 34.1%, and hypoalbuminemia was 9.8%. ConclusionOur search shows that combining the application of anthropometry and laboratory indexes can evaluate the nutritional status of patients with CKD. The most common nutritional problems in CKD patients include malnutrition, overweight and obesity, risk of malnutrition, and anemia. As for hypoalbuminemia, it is low in early CKD patients.
ObjectiveTo explore the changes of plasma prealbumin (PA), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) levels before and after treatment in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and analyze the correlation of PA and Hcy with hs-CRP and body mass index (BMI).MethodsA total of 132 hospitalized AECOPD patients with GOLD lung function as grade III-IV were recruited as an experimental group and 45 healthy subjects as a control group. The levels of plasma PA, Hcy and hs-CRP were measured by automatic biochemical analyzer, and the main indexes of pulmonary function were determined in all subjects.ResultsCompared with the control group, the level of plasma PA before and after treatment in the experimental group decreased significantly [(146.49±36.53) mg/L and (219.60±41.29) mg/L vs. (269.48±42.63) mg/L], the level of plasma Hcy before and after treatment increased significantly [(16.44±5.21) μmol/L and (12.61±4.56) μmol /L vs. (10.13±3.25) μmol/L], and the levels of plasma hs-CRP before and after treatment increased significantly [(45.24±29.94) mg/L and (7.71±3.41) mg/L vs. (5.01±1.52) mg/L] (all P<0.05). The levels of plasma PA, Hcy and hs-CRP after treatment were significantly better than before treatment in the experimental group (allP<0.01). The plasma PA values before and after treatment were negatively correlated with the level of hs-CRP before and after treatment, and positively correlated with BMI (bothP<0.05).ConclusionsThe levels of plasma PA, Hcy and hs-CRP are significantly different before and after the treatment in AECOPD patients and the healthy controls. PA is negatively correlated with hs-CRP and positively correlated with BMI. The detection of plasma PA and Hcy can help to determine the condition and efficacy of patients with COPD, and PA can reflect the level of inflammation and nutritional status to a certain extent.
ObjectiveTo investigate the prevalence of chronic obstructive pulmonary disease (COPD) with lipid metabolism disorders patients in Chengdu. MethodsWe randomly selected four communities from urban and rural areas in Chengdu between February and December, 2010, with multistage cluster random sampling method; 1 931 residents aged from 40 to 70 received special questionnaire from the BOLD Study, lung examination, blood biochemical examination, and physical examination. ResultsThe prevalence of COPD was 60.26% (91/151) with dyslipidemia; while non-COPD was 68.17% (972/1 428), and the difference was significant (P<0.05), in which the most obvious difference is triglycerides (TG). The prevalence of COPD was 6.62% (10/151) with underweight; while non-COPD was 4.97% (71/1 428), and the difference was significant (P<0.001). The prevalence of COPD was 21.19% (32/151) with abdominal obesity; while non-COPD was 30.81% (440/1 428), and the difference was significant (P<0.05). ConclusionThe prevalence of COPD with lipid metabolism disorders is lower than which with non-COPD in Chengdu. It provides an evidence for the nutrition support therapy in the treatment of COPD.
Objective To explore the relationship between obesity and the three targets including blood pressure, glucose, and lipid. Methods A total of 181 adult Tibetans who underwent physical examination between March and September 2015 at Xigaze People's Hospital were enrolled in this study. Their obesity degrees were assessed with body mass index (BMI) and waist circumference (WC) respectively. The levels of blood pressure, glucose, and lipid were compared at the different levels of BMI or WC. Results The incidence of systematic obesity and central obesity in these adults were 57.5% and 79.0%, respectively. Compared the overweight group with the normal BMI group, the systolic pressure and diastolic pressure of the former were 9.26 mm Hg (1 mm Hg=0.133 kPa) [95% confidence interval (CI) (3.46, 15.07) mm Hg, P=0.002] and 7.76 mm Hg [95%CI (3.96, 11.57) mm Hg, P<0.001] higher, respectively. Similarly, the systolic pressure and diastolic pressure of the central obesity group were 8.24 mm Hg [95%CI (1.03, 15.46) mm Hg,P=0.026] and 6.79 mm Hg [95%CI (2.03, 11.55) mm Hg, P=0.006] higher than those in the normal WC group, respectively. For the normal WC or normal BMI subjects, the detection rate of dyslipidemia reached up to 50.0% and 52.6%. Conclusions With the increase of BMI/WC values, the level of blood pressure rises. Even though WC or BMI is normal, the detection rate of dyslipidemia is high.
ObjectiveTo investigate the nutritional risk, incidence of malnutrition, and clinical application of nutrition support in hospitalized patients with gastric cancer by the nutritional risk screening (NRS) 2002 score summary table. MethodsFrom June 2009 to February 2010, nutritional risk screen and application of clinical nutritional support were carried out in the hospitalized patients with gastric cancer in this hospital. Nutritional risk was assessed case-by-case according to the severity of illness, nutritional status 〔including body mass index (BMI), recent changes in body weight and eating〕 and patients age. NRS ≥3 was accepted as nutritionally at-risk, while NRS lt;3 no nutritional risk; BMI lt;18.5 kg/m2 (or albumin lt;30 g/L) combined with clinical conditions was judged to be malnourished. Results Three hundreds and eighty-six patients were included, 329 of which completed the NRS2002 screening. One hundred and sixty-five patients (50.15%) were at nutritional risk, while another 164 (49.85%) were no nutritional risk. Malnutrition was found in 57 patients (17.33%). By gender, male malnourished patients and nutritionally at-risk patients were accounting for 16.45% (38/231) and 48.05% (111/231) respectively, while female nutritionally at-risk patients and malnourished patients were accounting for 55.1% (54/98) and 19.39% (19/98) respectively, 72.04% (237/329) of the screened patients accepted clinical nutrition support, among which, 115 patients were at nutritional risk, accounting for 69.70% in that group, and 122 patients were no nutritional risk, accounting for 74.39% in that group. ConclusionsThe incidences of malnutrition and nutritionally at-risk in hospitalized gastric cancer patients are high. And irrationality of clinical nutrition support exists. Evidence-based guidelines are required to improve the nutritional status of support.
ObjectiveTo analyze the latest epidemiological status of breast cancer in China, trends in morbidity and mortality from 1990 to 2019, and related prognostic risk factors.MethodsData on incidence and mortality of Chinese female breast cancer, their related age-standardized rates (ASRs) from 1990 to 2019, and attributable risk factors were obtained from the Global Burden of Disease (GBD) database, and data on disability-adjusted life years (DALYs) of 34 provinces in China were obtained from literature. Joinpoint regression analysis was used to analyze the trends of ASRs. The exposure levels of each attributable risk factor and the increased cancer burden were analyzed.ResultsThe incidence of breast cancer in Chinese females increased annually, from 17.07/100 000 in 1990 to 35.61/100 000 in 2019, while the mortality rate initially increased and decreased, and then exhibited an upward trend after 2016 and there was no obvious variation from 1990 (9.16/100 000) to 2019 (9.02/100 000). Among the 34 provinces of China, Shandong Province had the most serious breast cancer burden, while Macao Special Administrative Region had the lowest. Among the seven prognostic risk factors, high body mass index (BMI) contributed the most to the breast cancer burden and the exposure risk of a diet high in red meat had shown a significant increasing trend in the past 30 years. Therefore, the disease burden caused by a high red meat diet would be increasing.ConclusionsThe incidence rate of breast cancer in Chinese females is increasing. With the development of social economy and the change of people’s dietary habits, the breast cancer burden in China trends to become heavier and heavier. Therefore, it is necessary to conduct the "three early" prevention and treatment and advocate healthy and reasonable diet and living habits to reduce the burden of breast cancer to improve prognosis and quality of life.
ObjectiveTo systematically review the dose-response relationship between body mass index (BMI) and all-cause mortality in the elderly with frailty.MethodsPubMed, EMbase, Web of Science, CNKI, VIP, WanFang Data, and CBM databases were electronically searched to collect cohort studies on the association of BMI and mortality in frail adults from inception to November 2019. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies; Stata 15.0 software was then used to analyze the dose-response analysis of BMI and mortality by restricted cubic spline function and generalized least squares method.ResultsA total of 4 cohort studies involving 12 861 frail adults were included. Meta-analysis results showed that compared with normal BMI, the frail elderly who were overweight (HR=0.80, 95%CI 0.74 to 0.88, P<0.001) and obese (HR=0.89, 95%CI 0.79 to 1.00, P=0.047) had lower all-cause mortality. The results of dose-response meta-analysis showed that there was a non-linear relationship between BMI and all-cause mortality in the elderly with frailty (P value for nonlinearity was 0.035), for which the elderly with frailty had a BMI nadir of 27.5-31.9 kg/m2. For linear trends, and when BMI was less than 27.5 kg/m2, the risk of all-cause death was reduced by 4% for every 1 kg/m2 increase in BMI (RR=0.96, 95%CI 0.90 to 1.03, P=0.320), when BMI was greater than 27.5 kg/m2, the risk of all-cause death increased by 4% for every 1 kg/m2 increase in BMI (RR=1.04, 95%CI 1.03 to 1.05, P<0.001).ConclusionsThere is a paradox of obesity and a significant nonlinear relationship between BMI and all-cause mortality in the frailty elderly, with the lowest all-cause mortality in the frailty elderly at BMI 27.5-31.9 kg/m2. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusions.
Objectives To evaluate the effect of preoperative body mass index (BMI) on the perioperative and long-term results in esophageal squamous cell cancer patients. Method We retrospectively analyzed the clinical data of 503 patients with esophageal cancer between January 2001 and December 2009. There were 268 males and 235 females with the median age of 57 years ranging from 32-88 years. The associations between preoperative BMI and clinic patholo-gical characteristics were assessed by using the χ2 or Fisher's exact test. Survival analysis was performed by Kaplan-Meier curves with log-rank tests. ResultsThe 1-year, 3-year, 5-year, and 10-year overall survival rate for the entire cohort of patients was 64.0%, 49.0%, 43.0%, and 41.0% respectively. The occurance rates of weight loss, lymph node metastases, and poorly differentiated tumorigenesis represented statistically higher in patients with BMI≤18.5 kg/m2 than those in the patients with BMI>18.5 kg/m2 (P=0.026, P=0.006, P=0.048). For the cohort, the Kaplan-Meier survival analysis showed a significant trend toward a decreased survival in esophageal cancer patients with underweight (P=0.001). No statistical difference in overall complication, anastomotic leakage, and pulmonary complication rate was detected among the different BMI classes(P=0.162, P=0.590, P=0.376). Univariate and multivariate analysis showed that the drinking status, pathological stage, and underweight were the independent prognostic factors. ConclusionsAfter esophagectomy, BMI is not associated with the incidence of postoperative complications in patients. Patients with underweight are usually diagnosed with advanced stage, therefore tend to have poorer survivals than those with normal or over-weight.
ObjectiveTo investigate the existence of persistent systemic inflammation (PSI) among patients with chronic obstructive pulmonary disease (COPD) in local areas, and identify the risk factors of PSI.MethodsA total of 150 patients with stable COPD and 70 non-smoking healthy individuals were enrolled in our study. The levels of interleukin-6 (IL-6), IL-18 and activin A in serum were detected. Pulmonary function was tested, and basic information of the candidates was acquired at the same time. All of the patients were followed-up at 6 months, 12 months and 24 months for two years. The value at the 95th percentile of the concentration of inflammation markers of non-smoking healthy samples was defined as the threshold value, also known as normal ceiling limit value. Existence of PSI was defined as the condition that two or more kinds of inflammation markers exceed the threshold at each follow-up visit. The COPD patients were categorized into three classes, in which there were respectively none, one and two or more kinds of inflammation markers with over-threshold values. Based on a 2-year followup, patients with two or more kinds of inflammation markers exceeding threshold values were classified as PSI subgroup, and patients without inflammation markers exceeding threshold values as never inflamed subgroup.ResultsThere were 22 patients (14.7%) had persistent systemic inflammation, whereas 60 patients (40.0%) did not show evidence of systemic inflammation. Single factor analysis of two subgroups showed that the patients in PSI subgroup had higher body mass index (BMI), higher smoking index, higher prior frequency of time to exacerbation, higher proportion of patients at high risk for recurrent acute exacerbation during 2-year followup, higher SGRQ total score, lower FEV1%pred and lower FEV1/FVC ratio significantly (all P<0.05). Higher BMI and higher risk of recurrent acute exacerbation were independent risk factors leading to PSI, of which the higher risk of recurrent acute exacerbation had a more important effect on PSI.ConclusionsSome COPD patients have PSI in this region, which may constitute a novel COPD phenotype (called systemic inflammatory phenotype). Higher BMI and higher risk of recurrent acute exacerbation are independent risk factors leading to PSI. Individualized treatment to prevent acute exacerbation and appropriate weight control may be a better intervention for these patients.
