To identify the best evidence in the management of indicator, short and long term of prophylactic platelet transfusion in patient with myelodysplastic syndrome (MDS). We searched the latest evidence-based guidelines in PubMed,reviewed and appraised these guidelines. Clinical decision was made based on the guidelines and the actual patient with MDS. Perfect treatment effect was obtained through evidence-based clinical decision.
Objective To summarize results of the correlation of tumor necrosis factor-α (TNF-α) promoter –308A/G polymorphism with systemic lupus erythematosus (SLE) susceptibility in Chinese populations. Methods We collected all the publications about the correlation between TNF-α promoter –308A/G polymorphism and SLE in Chinese populations by searching PubMed, EBSCO, CBM, CNKI and Wanfang Data before the date of March 20, 2010. Meta-analysis was performed for checking the difference between two groups about genotypes such as AA versus GG, GA versus GG, AA versus GG+GA, GA+AA versus GG, and A allele versus G allele. Results A total of 8 studies involving 731 SLE patients and 901 healthy people were included. The meta-analysis of total populations showed that, there was no significant correlation between A allele and increased SLE risk (OR=1.42, 95%CI 0.97 to 2.09, P=0.07); the meta-analyses of populations in different regions showed there was no significant correlation of A allele and increased SLE risk in Chinese Taiwan populations (OR=1.04, 95%CI 0.77 to 1.40, P=0.82). Moreover, there was no significant difference between SLE group and control group in the genotypes of AA versus GG, GA versus GG, AA versus GG+GA, and GA+AA versus GG.Conclusion This meta-analysis dosen’t demonstrate the correlation between TNF-α promoter–308A/G polymorphism and SLE in Chinese populations.
During the medical rescue after the earthquake, the Security Department of West China Hospital understood those factors affecting the hospital safety in the earthquake disaster, established emergent communication platform and information release channel, and opened up special areas and passages for the wounded, so as to ensure smooth passages for the rescue work, security of disaster-relief materials as well as an orderly, safe and stable medical environment.
Objective To evaluate the expression of cyclin E and p27kip1 protein and their significance in gallbladder carcinoma. Methods SP immunohistochemistry was used to detect the expression of cyclin E and p27kip1 protein in 41 cases gallbladder carcinomas,15 cases chronic cholecystitis tissues. Results The positive rate of cyclin E in gallbladder carcinoma was 61.0%（25/41）,which was significantly higher than that in chronic cholecystitis (20.0%，3/15)，P＜0.05; The expression of cyclin E positively correlated with tumor TNM staging (r=0.314,P＜0.05). The positive rate of p27kip1 in gallbladder carcinoma was 53.7%(22/41),which was lower than that in chronic cholecystitis (100%). The positive rate of p27kip1 was decreased with the poor differentiation and progression of TNM staging. There was negative correlation between cyclin E and p27kip1 expression (r=-0.342,P＜0.05). Conclusion The high expression of cyclin E and the decreased expression of p27kip1 result in abnomal regulation of cell cycle,which may be associated with gallbladder carcinogenesis and progression.
The financial conflict of interests is drawing a wide attention, while several problems such as the unclarity of definition and blurred boundary of classification exist when it comes to the nonfinancial conflict of interests. Taking clinical practice guidelines as the example, this study introduce how nonfinancial conflict of interests happen, their classifications and impact based on present situation of relevant studies.
Adapting the existing guidelines in the context of specific regions can improve the efficiency of guidelines development, and reduce cost and time for developing guidelines. ADOLOPMENT is a methodological tool for guidelines adaptation, which was developed by the GRADE Working Group based on the standardized international guidelines making process. With ADOLOPMENT, developers can effectively use existing guidelines and evidence, avoid duplication of the evidence evaluation, and record the process from evidence to recommendations, which will ensure the transparency of adaptation, help users to understand the process, and improve the acceptability and credibility of guideline adaptation. This paper aims to introduce the ADOLOPMENT and its application.
The focus of health equity is to enable the public to have fair access to health services and achieve satisfactory health outcomes. With research developments, guideline developers increasingly pay more attention to the fairness in the practice guidelines and have carried out exploration and practice in the relevant guidelines. The GRADE working group has begun to investigate how to use GRADE to assess health equity in practice guidelines since 2014. In 2017, the series of methodological guidelines of health equity in guideline development was officially published. It proposed 5 approaches to evaluate health equity and pointed out current methodological challenges of applying GRADE to assess health equity. This paper aims to introduce the GRADE equity guidelines, so as to provide a reference for Chinese researchers in their practice.
Surgical management of osteoarthritis of the knee: evidence based guideline contains 38 recommendations pertaining to the preoperative, perioperative, and postoperative care of patients with knee osteoarthritis (KOA) who are considering surgical treatment. Compared with the domestic consensus on diagnosis and treatment for KOA, this clinical practice guideline (CPG) prepared by the American Academy of Orthopedic Surgeons (AAOS) has some advantages in terms of methodology selection and recommendation. Therefore, it is necessary for us to interpret this CPG to speed up the understanding and dissemination of the CPG. The ultimate aims are to: ① strengthen the standardization and understanding of surgical treatment of KOA; ② enhance the understanding of clinicians for this CPG in treating KOA; ③ speed up the development of guideline development methodologies in China; ④ provide methodological guidance for the development of CPG based on the current situation in China.
ObjectivesTo evaluate the reporting quality of clinical practice guidelines published in Chinese journals in 2015.MethodsCBM, CNKI, VIP and WanFang Data databases were searched to collect clinical practice guidelines published in Chinese journals from January, 2015 to December, 2015. Two reviewers independently screened literature, extracted data, and the reporting quality of clinical practice guidelines were evaluated by the Reporting Items for Practice Guidelines in Healthcare (RIGHT). Excel software was used for data analysis.ResultsA total of 74 clinical practice guidelines were included. It was found that among the seven domains of RIGHT, the reporting quality of basic information and background domains were acceptable. There were fewer problems in the domain of evidence and recommendation. There were many deficiencies in three domains, such as review and quality assurance, funding and the declaration/management of interests and other information.ConclusionsThe reporting quality of clinical practice guidelines published in Chinese journals in 2015 is low, and the full reporting rate of clinical practice guidelines need to be improved. It is suggested that guideline developers construct strict guidelines for the development and report the guidelines with international standard, thus improving the quality of the clinical practice guidelines.
ObjectivesTo systematically review the necessary factors of questionnaires design on patients' values and preferences in order to provide information on the most appropriate questionnaires when developing clinical practice guidelines.MethodsA systematic literature search of PubMed, EMbase, The Cochrane Library, CBM, CNKI and WanFang Data databases was performed to identify studies on questionnaires evaluating patient values and preferences. The authors included the articles that used fully structured questionnaires or scales with standardized questions and answer options. We assessed the questionnaires' construction with psychometric methodology and summarized the necessary factors on patients' preferences and values into the domains and items.ResultsTwenty articles were eventually included. Five out of 20 studies (25%, 5/20) described the process of item generation while merely one questionnaire (5%, 1/20) mentioned pilot testing. Regarding validity, there were 6 questionnaires (30%, 6/20) that assessed validity. For acceptability, the time taken to complete the questionnaires range from 10 to 30 minutes and only 6 studies reported response rates. The results showed that the factors affecting the design of questionnaires on patients' values and preference were related to the effectiveness, safety, prognostic factors and others. The main factors were the effects, side effects and risk of complications, risk of relapse and the cost of treatments.ConclusionsOnly a few studies have developed questionnaires with rigorous psychometric methods to measure patients' preference and values. There is still no valid or reliable questionnaires for patients' preference and values when developing clinical practice guidelines. Further study should be conducted to develop standardized instruments to measure patients' preference and values. It is suggested that the factors this study provides can be used in formulating questionnaires on patients' preference and values.
