Early mobilization on mortality of patients with mechanical ventilation in intensive care unit after discharge: a Meta-analysis / 中华危重病急救医学

Objective:To evaluate the effect of early mobilization on mortality in intensive care unit (ICU) patients with mechanical ventilation after discharge by Meta-analysis.Methods:Databases including SinoMed, China National Knowledge Infrastructure (CNKI), Wanfang data, PubMed, the Cochrane Library, Web of Science, and Embase were searched from inception to September 17th, 2020, to collect randomized controlled trials (RCT) about early mobilization on mortality of patients with mechanical ventilation in ICU after discharge, the references included in the literature were traced. The control group was given routine care, the experimental group was given early mobilization on the basis of the control group, including passive or active mobilization on the bed, sitting on the bed, standing by the bed, transferring to the bedside chair and assisting walking. The literature screening, data extracting, and the bias risk assessment of included studies were conducted independently by two reviewers. Stata 12.0 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 10 RCT studies involving 1 323 patients were included, with 660 patients in the control group and 663 patients in the experimental group. The results of literature quality evaluation showed that 7 studies were grade A and 3 studies were grade B, indicating that the overall quality of included literatures was high. The Meta-analysis results showed that early mobilization did not increase the mortality of patients with mechanical ventilation in ICU after discharge [odds ratio ( OR) = 0.92, 95% confidence interval (95% CI) was 0.75-1.13, P = 0.449]. Subgroup analysis results showed that early mobilization had a tendency to reduce the mortality of ICU patients with mechanical ventilation at 3, 6 and 12 months after discharge, but the difference was not statistically significant (3-month mortality: OR = 1.02, 95% CI was 0.74-1.40, P = 0.927; 6-month mortality: OR = 0.95, 95% CI was 0.70-1.27, P = 0.712; 12-month mortality: OR = 0.60, 95% CI was 0.33-1.10, P = 0.101). Funnel plot showed that the distribution of included literatures was not completely symmetrical, suggesting that publication bias might exist. Conclusions:Early mobilization does not increase the mortality of ICU patients with mechanical ventilation after discharge. Although it tends to have a favorable outcome in reducing mortality, and has a trend to reduce the mortality. However, due to the small number of included literatures, small sample size and differences in the specific implementation of early mobilization among various studies, a large number of high-quality RCT studies are still needed for further verification.

Current practice and obstacle factors of intensive care unit-acquired weakness assessment / 中华危重病急救医学

Objective:To investigate the current status of intensive care unit-acquired weakness (ICU-AW) assessment, analyze the assessment barriers, and to provide reference to improve ICU-AW assessment.Methods:A convenient sampling cross-sectional survey was conducted. First, an interview outline which based on related domestic and international literatures and combining with the research purpose of this study were designed. Thirteen medical personnel (8 ICU nurses, 3 ICU doctors, 1 respiratory therapist and 1 physiotherapist) who worked in the intensive care unit (ICU) of the First Hospital of Lanzhou University were enrolled with convenience sampling method to interview. Second, the topics were comprehensively analyzed and extracted, and then a questionnaire was constructed, and the reliability and validity was assessed. Finally, the questionnaire survey including the general situation of ICU medical staffs, the current practices of ICU-AW and influencing factors was implemented in China.Results:The retest reliability was 0.92 and expert validity was 0.96 of the questionnaire. There were 3 563 respondents in 31 provinces, municipalities and autonomous regions which eliminated 357 unqualified questionnaires, including 173 respondents from neonatal or pediatric ICU, 89 respondents whose working time was less than 6 months, and 95 invalid respondents, and then there were finally 3 206 valid questionnaires and the response rate were 90.0%. Those 3 206 respondents included 616 doctors (19.2%), 2 371 nurses (74.0%), 129 respiratory therapists (4.0%), 51 physiotherapist (1.6%) and 39 dietitians (1.2%). The mean age was (30.7±6.3) years old. Most of them had bachelor's degree (65.9%), master and above was 14.1%. Associate senior physician and above was 8.0%; ICU working time was (5.94±4.50) years. In clinical practice, only 26.5% of the ICU medical staffs confirmed that they had treated or taken care for ICU-AW patients; 52.9% of medical staffs evaluated ICU-AW only based on clinical experience, and only 12.3% used ICU-AW assessment tools. The majority of respondents believed that ICU-AW knowledge training should be performed (81.8%), ICU-AW assessment should be as important as other complications (pressure sore, infected ventilator associated pneumonia, etc., 75.1%), and ICU-AW assessment should be part of daily treatment and care activities (61.2%). However, only 10.2% of respondents had received ICU-AW related knowledge training, and 42.7% respondents believed that their ICU-AW related knowledge could not meet clinical needs. Only 18.7% respondents would actively assess whether patients suffered from ICU-AW or not, and 42.3% respondents thought that ICU-AW should be assessed every day, and the assessment tools were also inconsistent. There were 44.0% respondents considered the Medical Research Council Muscle score (MRC-score) scale was the optimal tool for diagnosing ICU-AW, the following were neuro-electrophysiological examination (17.2%) and manual muscle strength (MMT, 11.1%). The main cause of the ICU-AW assessment barriers was the lack of ICU-AW related knowledge (88.1%), and the following were lack of ICU-AW assessment guidelines (76.5%), patients' cognitive impairment or limited understanding ability (84.6%), unable to cooperate with the assessment due to critical illness (83.0%), and inadequate attention to ICU-AW assessment by the department (77.5%).Conclusion:The current status of ICU-AW assessment were unsatisfying in China, and the main barriers were lack of skills and knowledge.

Evaluation of pharmaceutical prevention and treatment of intensive care unit-acquired weakness: a Meta-analysis / 中华危重病急救医学

Objective:To evaluate the effect of preventing and treatment of pharmaceuticals on intensive care unit-acquired weakness (ICU-AW) by systematic review.Methods:The randomized controlled trials (RCTs) concerning pharmaceutical prevention and treatment about ICU-AW in SinoMed, CNKI, Wanfang data, PubMed, Cochrane Library, Web of Science, EMbase, and other sources were searched from their foundation to May 30th, 2019. The patients in the intervention group were treated with drugs to prevent or treat ICU-AW; and those in control group were treated with other rehabilitation methods. Data searching, extracting and quality evaluation were assessed by two reviewers independently. Stata 12.0 software was then used for Meta-analysis. Only descriptive analysis was conducted when only one study was enrolled.Results:A total of 11 RCTs were enrolled with 1 865 patients in the intervention group and 1 894 in the control group. The results of quality evaluation showed that 4 studies were A-level and 7 studies were B-level, indicating that the overall quality of the enrolled literature was high. Meta-analysis showed that intensive insulin therapy could prevent ICU-AW [relative risk ( RR) = 0.761, 95% confidence interval (95% CI) was 0.662-0.876, P = 0.000], but reduced phenylalanine loss (nmol·100 mL -1·min -1: -3±3 vs. -11±3, P < 0.05) and glutamine intake (nmol·100 mL -1·min -1: -97±22 vs. -51±13, P < 0.05). There was no significant difference in the prevention and treatment of ICU-AW between other drugs (including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin) and control group. Conclusions:Intensive insulin therapy can prevent ICU-AW, but the risk of hypoglycemia will increase. Other drugs including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin have no obvious advantages in the prevention and treatment of ICU-AW, so no drug has been recommended to prevent and treat ICU-AW.

Analysis on Funded and Completed Projects of Young Scientist Funds of National Natural Science Foundation of China in TCM Field from 1989 to 2015 / 中国中医药信息杂志

Objective To discuss the present situation and existing problems of the funded projects, especially in the gap between western region and eastern central region by analyzing the funding situation of the projects funded by the National Natural Science Foundation of China (NSFC) and the completed projects in the TCM field from 1989 to 2015. Methods The website was searched thoroughly, and data of Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 (ie TCM, Chinese materia medica and integrated traditional Chinese and Western medicine) funded by the National Science Foundation for Young Scientists in China were obtained, and the projects of the National Science Foundation for Young Scientists funded by Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 were included, and incomplete or inavailable items were eliminated. Relevant information according to the extracted forms was extracted. The situation of different regions and the situations of the projects have been concluded and the titles of different titles have been analyzed. Results By 2015, the number of funded projects and the amount of financing in the TCM field were increasing year by year. In the western regions, the number of funded projects and the amount of financing accounted for only 11.29% of the total number and 11.28% of the total financing. Compared with the less supporting western regions, much more were mainly in eastern and central regions. The number of SCI papers published and single cited times of the finished projects were 988 and 20.85. Compared with the developed areas in eastern and central regions, there was no statistical significance in the average number of SCI papers (P=0.493), average SCI papers cited article number (P=0.449), SCI papers in average cited frequency (P=0.589), the average CSCD papers number (P=0.579), average CSCD papers cited article number (P=0.883) and average single CSCD papers cited frequency (P=0.753) in western regions (P>0.05). Conclusion Under the stable supports of the Young Scientists Fund, scientific researches in the TCM field have achieved remarkable achievements. In addition, the ability of scientific research and innovation of the young scientific workers have been improved. The funded projects in western regions are far less than those in eastern and central regions, with great differences. However, there is no statistical significance in the research results of the items in western regions and eastern and central regions.

Objective To understand the dominant pathogens of febrile respiratory syndrome (FRS) patients in Gansu province and to establish the Bayes discriminant function in order to identify the patients infected with the dominant pathogens.Methods FRS patients were collected in various sentinel hospitals of Gansu province from 2009 to 2015 and the dominant pathogens were determined by describing the composition of pathogenic profile.Significant clinical variables were selected by stepwise discriminant analysis to establish the Bayes discriminant function.Results In the detection of pathogens for FRS,both influenza virus and rhinovirus showed higher positive rates than those caused by other viruses (13.79％,8.63％),that accounting for 54.38％,13.73％ of total viral positive patients.Most frequently detected bacteria would include Streptococcus pneumoniae,and haemophilus influenza (44.41％,18.07％) that accounting for 66.21％ and 24.55％ among the bacterial positive patients.The original-validated rate of discriminant function,established by 11 clinical variables,was 73.1％,with the cross-validated rate as 70.6％.Conclusion Influenza virus,Rhinovirus,Streptococcus pneumoniae and Haemophilus influenzae were the dominant pathogens of FRS in Gansu province.Results from the Bayes discriminant analysis showed both higher accuracy in the classification of dominant pathogens,and applicative value for FRS.

Evaluation of estimation of prevalence ratio using bayesian log-binomial regression model / 中华流行病学杂志

To evaluate the estimation of prevalence ratio (PR) by using bayesian log-binomial regression model and its application,we estimated the PR of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea in their infants by using bayesian log-binomial regression model in Openbugs software.The results showed that caregivers' recognition of infant's risk signs of diarrhea was associated significantly with a 13％ increase of medical care-seeking.Meanwhile,we compared the differences in PR's point estimation and its interval estimation of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea and convergence of three models (model 1:not adjusting for the covariates;model 2:adjusting for duration of caregivers' education,model 3:adjusting for distance between village and township and child month-age based on model 2) between bayesian log-binomial regression model and conventional log-binomial regression model.The results showed that all three bayesian log-binomial regression models were convergence and the estimated PRs were 1.130(95％CI:1.005-1.265),1.128(95％CI:1.001-1.264)and 1.132(95％CI:1.004-1.267),respectively.Conventional log-binomial regression model 1 and model 2 were convergence and their PRs were 1.130(95％ CI:1.055-1.206) and 1.126(95％ CI:1.051-1.203),respectively,but the model 3 was misconvergence,so COPY method was used to estimate PR,which was 1.125 (95％CI:1.051-1.200).In addition,the point estimation and interval estimation of PRs from three bayesian log-binomial regression models differed slightly from those of PRs from conventional log-binomial regression model,but they had a good consistency in estimating PR.Therefore,bayesian log-binomial regression model can effectively estimate PR with less misconvergence and have more advantages in application compared with conventional log-binomial regression model.

Effect of combination model on fitting cancer mortality and prediction / 中华流行病学杂志

Objective To reduce the cancer burden in the Jinchang cohort and provide evidence for developing cancer prevention strategies and performing effectiveness evaluation in the Jinchang cohort.We are fitting thirteen years of cancer mortality data from the Jinchang cohort by using six kinds of predicting methods to compare relative fitness and to select good predicting methods for the prediction of cancer mortality trends.Methods The mortality data of cancer in Jinchnag cohort from 2001-2013 were fitted using six kinds of predicting methods:dynamic series,linear regression,exponential smoothing,autoregressive integrated moving average (ARIMA) model,grey model (GM),and Joinpoint regression.Weight coefficients of combination models were calculated by four methods:the arithmetic average method,the variance inverse method,the mean square error inverse method,and the simple weighted average method.Results The cancer mortality was fitted and compared by using six kinds of forecasting methods;the fitting precision of the Joinpoint linear regression had the highest accuracy (87.64％),followed by linear regression (87.32％),the dynamic series (86.99％),GM (1,1) (86.25％),exponential smoothing (85.72％) and ARIMA (1,0,0) (81.98％),respectively.Prediction accuracy of the combination model derived from GM (1,1) and linear regression (＞99％) was higher than that of the combination model derived from ARIMA (1,0,0) and GM (1,1).The combination model derived from the GM (1,1) and linear regression,with weight coefficients based on the arithmetic average method and the mean square error inverse method,had the best prediction effect of the four weight calculation methods.Conclusion Prediction accuracy of the combination model,with accuracy ＞95％,was higher than that of the single prediction methods.

Each group was given one intervention every 4 hours until infant eated. Group Ⅳ was given no interventions. Bowel sounds recovery time, first bowel movement time for the first time were compared. SPSS 17.0 software was used for statistical analysis. Results A total of 82 infants completed the clinical observation. Bowel sounds recovery time of group Ⅰ,Ⅱ,Ⅲ were (28.54±9.93), (34.10±9.43), (28.50±9.52) h, while first bowel movement time were (50.02±11.60), (57.65±15.28), (49.97±15.46) h, which were earlier than group Ⅳ whose bowel sounds recovery time and first bowel movement time were (39.55 ±11.22) h, (65.43 ±14.78) h. The bowel movement time and first bowel movement time of group Ⅲ were earlier than that of groupⅡ (P0.05). Conclusions Infants early sucking a lollipop and pacifier after gastrointestinal operation help gastrointestinal function recovery, but the lollipop is superior to the pacifier, lollipops and no interaction between pacifier.

Spatial clustering of hand-foot-mouth disease in Gansu, 2012 / 中华流行病学杂志

<p><b>OBJECTIVE</b>The purpose of this study was to explore the spatial distribution and spatial clustering of hand-foot-mouth disease (HFMD) in Gansu, 2012.</p><p><b>METHODS</b>Spatial autocorrelation and Spatial scanning analysis were used to conduct spatial statistical analyses for the HFMD at the county/district level.</p><p><b>RESULTS</b>HFMD cases did not show a random distribution but with significant spatial aggregation. When Local Autocorrelation analysis was applied at the county/district level, with nine hot spot areas as Jiayuguan, Yumen, Dunhuang, Jinta, Suzhou, Chengguan, Anning, Xigu and Gaolan, were discovered. Four statistically significant HFMD clusters were identified by spatial scan statistics.</p><p><b>CONCLUSION</b>HFMD was noticed geographically clustered in Gansu in 2012. Results from this study indicated that the spatial autocorrelation and spatial scanning analysis could effectively detect the areas which presenting significant clusters. Cluster Detection System (CDS) could provide evidence for the development of an effective measure concerning the prevention and control of HFMD.</p>

Analysis of risk factor on anemia in renal transplant recipients over 60 years old / 中华肾脏病杂志

Objective To investigate the characteristics and risk factors of anemia in renal transplant recipients over 60 years old.Methods Clinical data of one hundred and sixty-eight renal transplant recipients over 60 years old were retrospectively analyzed.Logistic regression analysis was used to determine the risk factors of anemia.Results In 168 cases of renal transplant recipients,the incidence of anemia was 45.2％(76/168).Forty cases were normocyte and normochromic,26 cases were microcytic hypochromic,10 cases were hemolytic anemia.In these anemic recipients,51 cases were short of erythropoietin (EPO),25 were EPO resistance.The incidence of malnutrition and cardia-cerebrovascular complication was higher in recipients with anemia than those without anemia (P＜0.01).The incidence of anemia in CsA+Aza+Pred treatment was 57.1％,which was significantly higher as compared to other three treatments (P＜0.01).Unconditional multivariate Logistic regression analysis revealed that male,creatinine level,acute reject reaction,delayed graft function (DGF) were the independent predictors of anemia,the corresponding OR values were 1.089,5.156,6.345,1.876.Conclusions Anemia is a common and serious complication in renal transplant recipients over 60 years old.Male,creatinine level,acute reject reaction,DGF are the independent risk factors of anemia in renal transplant recipients over 60 years old.

Correlation research of myeloperoxidase and the severity of coronary lesions in patients with acute coronary syndrome / 中国医师进修杂志

ObjectiveTo research the relationship between the plasma levels of myeloperoxidase (MPO) and the onset and progress of acute coronary syndrome (ACS) and the severity of coronary lesions in patients with ACS.MethodsSeventy-eight patients hospitalized with chest pain were enrolled,including 41 patients with ACS (ACS group),17 patients with stable angina pectoris(SAP,SAP group) and 20 patients serving as control (control group).Forty-one patients undergoing coronary angiography were divided into single vessel lesions group (7 patients),double vessel lesions group (7 patients),multiple vessel lesions group ( 12 patients) and no vessel lesions group ( 15 patients) based on the vessel lesions of the left anterior descending,left circumflex artery and right coronary artery.According to the diameter stenosis of major coronary artery,there were 15 patients in no vascular stenosis group,2 patients in mild vascular stenosis group,6 patients in moderate vascular stenosis group and 18 patients in severe vascular stenosis group.The levels of MPO were measured by enzyme-linked immunosorbent assays(ELISA).ResultsThe levels of MPO in ACS group [( 252.10 ± 27.07 ) μ g/L]were higher than those in SAP group[( 185.81 ± 17.85 ) μ g/L]and control group [( 140.42 ± 71.40) μ g/L](P ＜ 0.05 ),the levels of MPO in SAP group were higher than those in control group(P＜ 0.05 ).The levels of MPO in single vessel lesions group and multiple vessel lesions group were higher than those in no vessel lesions group (P ＜ 0.05 ),but there was no significant difference among single vessel lesions group,double vessel lesions group and multiple vessel lesions group (P ＞ 0.05 ).The levels of MPO in mild vascular stenosis group,moderate vascular stenosis group and severe vascular stenosis group were higher than those in no vascular stenosis group (P ＜ 0.05),but there was no significant differenceamong mild vascular stenosis group,moderate vascular stenosis group and severe vascular stenosis group(P ＞ 0.05 ).A positive correlation was observed between the levels of MPO and neutrophils (r =0.288,P=0.018 ),creatine kinase isoenzyme-MB(r =0.469,P=0.043 ),subject groups( r =0.757,P=0.000),vessel lesions (r =0.584,P=0.000) and the degree of vascular stenosis (r =0.491,P=0.001).Conclusion MPO may predict ACS and reflect the severity of coronary lesions in ACS as a novel inflammatory marker.
