Recommendations of Clinical Practice Guidelines of Stroke Rehabilitation / 中国康复理论与实践

@#Objective To analyze the contents of the recommendations of stroke clinical rehabilitation guidelines in order to provide advice for the development and implementation of stroke rehabilitation guidelines.Methods PubMed, EMBASE, CNKI, China Biology Medicine disc, Wanfang databases and guideline-related websites were retrieved from the date of establishment to January 2020, to collect stroke clinical rehabilitation guidelines. The main content, recommendations based on evidence, the type of evidences, and the scope of evidence classification had been explored based on World Health Organization Handbook for Guideline Development-2nd Edition.Results A total of twelve guidelines were included in this study, one in Chinese and eleven in English. They were from the United States (3 guidelines), United Kingdom (3 guidelines), Canada (3 guidelines), Australia (2 guidelines) and China (1 guidelines), and published from September, 2005 to February, 2019. Three articles (25.0%) used the Appraisal of Guidelines for Research and Evaluation (AGREE) for quality evaluation, and two articles (16.7%) used Grading of Recommendations Assessment, Development and Evaluation (GRADE) as the grading system. The recommendations covered the areas such as: cognitive dysfunction (4 dimensions) with a recommendation of cognitive function assessment at most (7 guidelines, 66.7%), language and swallowing dysfunction (5 dimensions) with a recommendation of swallowing-related complications at most (10 guidelines, 83.3%), motor dysfunction (6 dimensions) with a recommendation of spasm treatment at most (10 guidelines, 83.3%), and psychological and behavioral dysfunction (4 dimensions) with a recommendation for assessment or monitoring at most (6 guidelines, 50.0%). There were many recommendations in these areas, but the types of evidence were different, and observational studies and/or randomized controlled trials accounted for most.Conclusion There are different types of evidence and levels of recommendation strength. It is proposed for future guideline developers in stroke rehabilitation to follow World Health Organization Handbook for Guideline Development-2nd Edition to improve the quality and the overall implementation of the rehabilitation guidelines, and to improve the quality and safety of rehabilitation.

Clinical Practice Guidelines of Rehabilitation: Composition of Expert Group and Situation of Conflict of Interest / 中国康复理论与实践

@#Objective To evaluate and analyze the panel composition and conflict of interest management of clinical practice guidelines of rehabilitation.Methods Clinical practice guidelines of rehabilitation were systematically retrieved from PubMed, EMBASE, China Biology Medicine disc, CNKI, Wanfang Data and Medlive database, the National Institute for Health and Care Excellence, National Guideline Clearinghouse, The Scottish Intercollegiate Guidelines Network, World Health Organization (WHO) and Guidelines International Network until January 11, 2020. Two researchers independently screened and cross-checked the literatures, and extracted the basic information of included guidelines, including the title, formulating institution, published journol, as well as the expert group, the number of expert group, the specific division of labor and their discipline, affiliation and the geographic location, the statement and management of conflict of interest, types of conflicts of interest, and whether to accept fund and the source of the fund.Results A total of 84 guidelines were finally included, 17 domestic ones and 67 foreign ones, in which, 52 (61.9%) reported the expert panel; 22 (26.2%) reported the number of expert panel groups, 21 (25.0%) indicated the specific division of work among the members of the expert panel, 74 (88.1%) reported the names of the members of the expert panel, 47 (56.0%) reported the subjects and specialties of the panelists, 70 (83.3%) reported the affiliation and location of panelists, 14 (16.7%) mentioned the management of conflicts of interest, and 25 (29.8%) reported if there were conflicts of interest. Only five of the 16 funded guidelines stated that there was no conflict of interest between the funding and the development of the guidelines. Among them, the reporting rate of expert panel was significantly higher in foreign countries than in China (χ2 = 9.542, P < 0.01), the reporting rate of name of expert panel members and specific division of labor were higher in foreign countries than in China ( χ2 > 4.155, P < 0.05), and the reporting rate of conflict of interest management was also higher in foreign countries than in China ( P < 0.05). There was no significant difference in whether there was a conflict of interest, whether it was funded and the type of funding at home and abroad ( P > 0.05). Conclusion In gerenal, clinical practice guidelines of rehabilitation published at home and abroad are necessary to be improved in the reporting quality of expert group formulation and division of labor, conflict of interest reporting and management. It is proposed that future guideline developers should follow the WHO Handbook for Guideline Development, assign roles of experts, strengthen the management and reporting of conflicts of interest, and standarderize the development process and reporting of the guidelines.

Correlation of cadherin-17 protein expression with clinicopathological features and prognosis of patients with sporadic gastric cancer

This study aimed to explore the correlations between cadherin-17 (CDH17) protein expression and the clinicopathological features and prognosis of patients with sporadic gastric cancer (GC). Nine relevant studies of 1,960 patients were identified using electronic database searches supplemented with a manual search in strict accordance with inclusion and exclusion criteria. Statistical analyses were conducted using STATA 12.0 statistical software. Relative risks and 95% confidence intervals were determined, and Z test was used to measure the significance of the overall effect size. A total of nine eligible cohort studies were included in this meta-analysis. The expression of CDH17 in patients with diffuse GC was significantly higher than in those with intestinal-type GC. Moreover, the tumor depth of invasion differed significantly between patients with positive CDH17 (CDH17+) and negative CDH17 (CDH17-) GC. However, there were no significant differences between CDH17+ and CDH17- GC patients with respect to tumor node metastasis clinical stages, histological grades, or lymph node metastasis. Despite the differences in invasive depth, there was no significant difference in 5-year survival rates between CDH17+ and CDH17- GC patients. Our meta-analysis provides evidence that CDH17 protein expression may be associated with the development of GC, suggesting that CDH17 is an important biomarker that could be useful for the early diagnosis of GC. However, CDH17 levels do not appear to impact overall survival.

Performance assessment of the single photon emission microscope: high spatial resolution SPECT imaging of small animal organs

The single photon emission microscope (SPEM) is an instrument developed to obtain high spatial resolution single photon emission computed tomography (SPECT) images of small structures inside the mouse brain. SPEM consists of two independent imaging devices, which combine a multipinhole collimator, a high-resolution, thallium-doped cesium iodide [CsI(Tl)] columnar scintillator, a demagnifying/intensifier tube, and an electron-multiplying charge-coupling device (CCD). Collimators have 300- and 450-µm diameter pinholes on tungsten slabs, in hexagonal arrays of 19 and 7 holes. Projection data are acquired in a photon-counting strategy, where CCD frames are stored at 50 frames per second, with a radius of rotation of 35 mm and magnification factor of one. The image reconstruction software tool is based on the maximum likelihood algorithm. Our aim was to evaluate the spatial resolution and sensitivity attainable with the seven-pinhole imaging device, together with the linearity for quantification on the tomographic images, and to test the instrument in obtaining tomographic images of different mouse organs. A spatial resolution better than 500 µm and a sensitivity of 21.6 counts·s-1·MBq-1 were reached, as well as a correlation coefficient between activity and intensity better than 0.99, when imaging 99mTc sources. Images of the thyroid, heart, lungs, and bones of mice were registered using 99mTc-labeled radiopharmaceuticals in times appropriate for routine preclinical experimentation of <1 h per projection data set. Detailed experimental protocols and images of the aforementioned organs are shown. We plan to extend the instrument's field of view to fix larger animals and to combine data from both detectors to reduce the acquisition time or applied activity.
