ObjectiveTo summarize regional and body distributions, diagnosis, treatment, and prognosis of echinococcosis outside liver in China. MethodsThe published literatures about echinococcosis outside liver in China (not including Hong Kong, Macao and Taiwan regions) from 2000 to 2015 were searched in the databases of CNKI and Wanfang. Data were extracted by using a standardized form and a retrospective clinical analysis was performed. ResultsA total of 66 published literatures about echinococcosis outside liver and data of 884 cases reported were collected. The regional proportions of cases reported were different, five high regions were Xinjiang (68.73%), Tibet (8.77%), Ningxia (6.75%), Qinghai (6.41%), Gansu (5.62%). The organ distributions of cases reported were also different, five high organs were lung (61.09%), bone (9.95%), brain (9.73%), spleen (8.60%), and kidney (6.22%). The main clinical symptoms of patients with echinococcosis outside liver included general asymptoms and organ dysfunction, and the most common examinations were X-ray (30.77%), B ultrasound (7.47%),CT(17.43%), MR (1.59%), and laboratory (36.31%). The main therapy choice was operation (73.30%), and some patients were performed operation combined with drug therapy. ConclusionRegional distribution of echinococcosis outside liver is almost the same as total echinococcosis, and distributed more in organs rich in blood supply, its clinical diagnosis mainly depends on imaging and immunology examination, and operation is still the main therapy choice.
Objective To conduct bibliometric analysis of systematic review and meta-analysis published in the Chinese Journal of Evidence-based Medicine. Methods Based on the Chinese academic periodical network as a data pool, literature on systematic reviews (involving meta-analysis) and clinical decision-making researches were retrieved in the Chinese Evidence-Based Medicine Magazine from 2001 to 2010, screened and categorized by the medical and hygienic standards of Chinese Library Classification (fourth edition), and then were counted and sorted. Results There were 425 articles about systematic reviews (involving meta-analyses) and clinical decision-making studies in the Chinese Evidence-Based Medicine Magazine, with an yearly increasing number. Basically, those articles involved all subjects such as clinical medicine, preclinical medicine, hygenics, pharmacy, and traditional Chinese medicine. Conclusion Development levels of evidence-based research in medical subjects are different, each of which has its own feature. Also, some systematic reviews do not strictly follow the Cochrane Handbook. Therefore, high-quality systematic review is still needed in each subject.
Objective To analyze the complaint characteristics of emergency department of women and children’s specialized hospital, and to provide a basis for improving medical service quality, enhancing hospital management, increasing satisfaction, and reducing complaint rates in specialized hospitals. Methods Using the Healthcare Complaint Analysis Tool classification framework, a retrospective analysis was conducted on complaints from the Emergency Department of West China Second University Hospital of Sichuan University. Results The total number of complaints from 2020 to 2022 was 525, and the number of complaints had been increasing year by year. There were 196 complaints against personnel and 329 complaints against regions. There were 320 complaints related to management issues (61.0%), 143 complaints related to doctor-patient relationship issues (27.2%), and 62 complaints related to clinical issues (11.8%). The complained areas were mainly fever clinics (193 cases), and the complained personnel were mainly nurses (82 cases). Conclusion The emergency department of women and children’s specialized hospitals is different from comprehensive hospitals, and active optimization should be carried out to address the main issues. While continuously improving the level of medical technology, it is also necessary to strengthen information technology construction, optimize medical procedures, improve environmental facilities, and provide psychological support for patients and their caregivers.
ObjectiveTo analyze the status quo of outcome indicators in the randomized controlled trials (RCTs) of premature ovarian failure (POF)/primary ovarian insufficiency (POI) published at home and abroad, and provide a sufficient basis for the selection of outcome indicators in related studies in the future.MethodsChina National Knowledge Infrastructure, Chongqing VIP Data, Wanfang Data, SinoMed, PubMed, the Cochrane Library, and Embase were searched for RCT articles of POF/POI published between the establishment of the databases and June 2021. Two researchers independently screened and extracted the literature, and finally summarized the outcome indicators of the included studies.ResultsA total of 186 articles meeting the inclusion criteria were selected, including 180 articles in Chinese and 6 articles in English. The choice of outcome indicators was diverse. Of the 186 articles, 2 Chinese articles and 1 English article used primary and secondary outcome indicators; 19 Chinese articles and 4 English articles used independent indicators, 4 Chinese articles used composite indicators, and 157 Chinese articles and 2 English articles used both independent indicators and composite indicators.ConclusionsThe selection and use of outcome indicators in clinical RCTs of POF/POI are not standardized, and there are problems such as neglect of primary and secondary outcome indicators, and lack of standards for the selection of clinical research outcome indicators. As a result, the credibility of the curative effect is reduced, and the results of similar studies cannot be combined and compared.
Objective To analyze retrospectively the 1861 wounded inpatients and deaths in West China Hospital of Sichuan University after the Wenchuan earthquake, so as to provide reference for the improvement of emergency plans for the disaster of earthquake and the establishment of state-level regional medical centers. Methods The analysis was based on the data provided by the Department of Information of the Hospital up until July 23. The software of Microsoft EXCEL was used for data input, and SPSS 11.5 was used for statistical analysis. Results Up to July 23, 2728 cases from the disaster area have been treated in the hospital, of whom 872 were admitted into the emergency department and 1856 into the inpatient department (974 men, median age 43 years; 882 women, median age 46 years). Most patients were sent to the hospital within the first 2 weeks after the quake (82.4%), and the number of inpatients reached its peak on Day 8 after the quake (976 cases). The majority of the inpatients were discharged on Day 9 to Day 18 after the quake (60.2%). The wounded were mainly from Deyang, Aba Prefecture and Dujiangyan. The admission diagnoses were mainly fracture (54.84%), craniocerebral injury (9.81%) and thoracoabdominal injury (7.54%). There were totally 33 deaths, including 5 pre-hospital deaths, 1 emergency death and 27 inpatient deaths. Conclusion The development of an emergency plan for the medical rescue after an earthquake disaster is an essential step to enhance the emergent response capability, improve the scientific process of field triage, transport and transfer, and ensure the rational allocation and application of healthcare resources after any unexpected big disasters in the future.
Objective To analyze the outcome of patients with Blunt Abdominal Injury (BAI) in the Deyang People’s Hospital after the Wenchuan Earthquake, in order to provide evidence for future improvement in emergency response after earthquakes and in the treatment of BAI patients. Methods Data on the BAI patients within 1 week after the earthquake were collected from the Information Department of the Hospital. Microsoft EXCEL was used for data input. Results A total of 23 BAI inpatients were treated, of whom 15 were from Mianzhu City and sent to hospital within 12 hours of the earthquake. This was 1.9% of the total inpatients. The BAI inpatients suffered severe and complex injuries, and 5 of them died (mortality rate: 22%). Linenectomy was conducted for patients with spleen injuries and two inpatients developed incision infection due to lack of antibiotics during the perioperative period. Conclusions It is important to establish an emergency response mechanism for medical rescue for patients with the viscera injury, including BAI, after an earthquake. This would help to guarantee rational allocation of the rescue workers, triage of the wounded, optimization of operation, as well as a reduction in mortality from BAI.
ObjectiveTo systematically review the efficacy and safety of chemo-radiotherapy combined with hyperthermia (HCRT) for rectal cancer, and to provide evidence for clinical practice. MethodsWe searched the Cochrane Library (Issue 6, 2014), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases from inception to July 2014. All relevant randomized controlled trials (RCTs) of HCRT for rectal cancer were collected. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 9 RCTs involving 663 patients were included. The results of meta-analysis showed that:Compared with the chemo-radiotherapy (CRT) group, the HCRT group were significant superior in complete response (OR=3.74, 95%CI 2.14 to 6.53), total effective rate (OR=4.23, 95%CI 2.69 to 6.66), 3-year survival rate (OR=4.48, 95%CI 1.81 to 11.06) and recurrence rate (OR=0.19, 95%CI 0.09 to 0.42). ②Compared with the radiotherapy (RT) group, the HCRT group was associated with significant improvement in complete response rate (OR=3.01, 95%CI 1.24 to 7.29). ConclusionCurrent evidence shows, HCRT is superior to CRT or RT in the treatment of rectal cancer. However, due to the limited quantity and quality of the included studies, more high quality studies are needed to verify the above conclusion.
Covariates are factors which have significant impacts on the primary analysis prior to the subjects being treated. Covariates adjustment should be considered in the design and analysis stages of the clinical trial. Through controlling in the design stage is the optimal resolution; randomization, stratified randomization and restricted covariant values could be used to balance the covariates between comparative treatments. During data analysis stage, analysis of covariance, stratified analysis, linear or generalized linear model can be conducted for covariate adjustment according to different types of outcome and covariate. For confirmatory clinical trial, covariates should be defined in advance in the protocol and statistical analysis plan with the main statistical model.
Objective Secondary osteoporosis is very common in patients with primary osteoporosis. Diabetes is a known cause of secondary osteoporosis. While type I diabetes has been clearly linked with diabetic osteoporosis, the effect of type II diabetes on bone health is controversial.Methods In the present study, we investigated the associations between type II diabetes and osteoporosis as well as fractures at different skeletal sites in Women’s Health Initiative participants.Results Common risk factors such as age, race, BMI, HRT use, and the history of fractures were significantly associated with osteoporosis and fractures in this study population. Diabetic women appeared to have a decreased risk of osteoporosis although it no longer remained significant after adjusting for other risk factors (crude HR=0.78, 95%CI 0.61 to 0.99; adjusted HR=0.93, 95%CI 0.73 to 1.19). The impact of diabetes on fractures varied at different body sites. There was a significant increase of risk of hip fracture (HR=2.54, 95%CI 1.14 to 5.66), but not spine fracture (HR=1.71, 95%CI 0.81 to 3.60) and arm fracture (HR=0.92, 95%CI 0.48 to 1.76) among the women with diabetes. Although the overall risk of fractures in diabetic women did not differ significantly from non-diabetic women (HR=1.37, 95%CI 0.89 to 2.09), the difference had a two-fold increase and was statistically significant after 2,000 days (HR=2.01, 95%CI 1.21 to 3.35), indicating a different hazard at different stages of diabetes.Conclusion Our findings suggest that type II diabetes may not be clearly associated with osteoporosis, it increases a site-specific fracture risk at least in the hip. In addition, the overall fracture risk appears to increase in a time-dependent manner.
ObjectiveTo analyze the effectiveness of PDCA cycle model in antibiotics management by comparison of antibiotics use before and after the use of PDCA in a tertiary hospital. MethodsProspective study was adopted to analyze the using rate of antibiotics in outpatients, emergent patients and inpatients between June 2011 and December 2013. ResultsThe reasonable antibiotics use was improved since the beginning of PDCA cycle model. The antibiotics using rates of outpatients were 33.00%, 29.09% and 19.31%, of emergent patients were 45.00%, 32.81% and 28.94%, and of inpatients were 71.00%, 57.76% and 53.28% in year 2011 (from June to December), 2012 (from January to December) and 2013 (from January to December) respectively. Meanwhile, ClassⅠ incision antimicrobial use also decreased and bacteria examination rate continuously increased during the last three years. As a consequence, patients' cost was reduced. ConclusionThe PDCA cycle model promotes the standardized management of clinical medication application.
