ObjectiveTo assess the methodological quality of guidelines for bronchoscopic alveolar lavage. MethodsCNKI, VIP, WanFang Data, CBM, Web of Science, PubMed, EMbase databases and medlive.cn, the National Guideline Clearinghouse (NGC), the National Guideline International Network (GIN), the Scottish Intercollegiate Guidelines Network (SIGN), the National Institute for Clinical Excellence (NICE), and the World Health Organization (WHO) websites were electronically searched to collect guidelines of bronchoscopic alveolar lavage from inception to December 2020. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of the guidelines by using AGREE Ⅱ tool. ResultsA total of 19 guidelines were included, with 5 from China, 5 from the USA, 3 from Europe, 2 from the UK, 1 from Australia, 1 from Israel, 1 from Spain, and 1 from India. The average standard score rates of the 19 guidelines in the six fields were 50.73% for scope and purpose, 20.02% for participants, 15.13% for formulation rigor, 36.40% for clarity of presentation, 3.51% for applicability, and 22.37% for editorial independence.ConclusionsThe quality of bronchoalveolar lavage guidelines remains relatively low.
ObjectiveTo explore the effect of family-school-hospital application in continuous nursing care for children with epilepsy. Methods120 children with epilepsy admitted to Children's Hospital Affiliated to Jiangnan University from January 2021 to October 2022 were randomly divided into two groups, each with 60 cases. The control group received routine care, while the experimental group received family-school-hospital continuous care. Compare the awareness of epilepsy knowledge, disease control effectiveness, medication compliance, negative emotions, physical and mental status, and quality of life before and after nursing between the families of two groups of children with epilepsy. ResultsAfter 2 months of nursing care, the scores of family members' knowledge of epilepsy in the experimental group were higher than the control group (P<0.05). The effect of disease control in the experimental group was better the control group (P<0.05). The drug compliance of the experimental group was higher than the control group (P<0.05). The quality of life score in the intervention group was higher than the control group (P<0.05). ConclusionThe application of family-school-hospital in the continuous care of children with epilepsy can improve their family members' awareness of epilepsy knowledge, effectively control the disease, improve medication compliance, improve negative emotions and physical and mental conditions, and thus improve the quality of life of children.
ObjectivesTo evaluate the methodological quality of guidelines for pharmacological intervention of migraine in adults, to compare and analyze the differences in first-line drug recommendations in different regions and quality levels, so as to explore the evidence of drug recommendations, and provide a basis for clinical decision-making.MethodsPubMed, The Cochrane Library, EMbase, SinoMed, CNKI, VIP, and WanFang Data databases, Up To Date, as well as the related books, Yimaitong, Guideline Central, Guidelines International Network (GIN) and National Institute for Health and Clinical Excellence (NICE) were systematically searched to collect pharmacological intervention guidelines of migraine in adults from inception to January 12th, 2020. The methodological quality of the guidelines was evaluated by Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ).ResultsA total of 25 guidelines were included (including 22 evidence-based guidelines), covering 10 countries on 4 continents and World Health Organization (WHO) with a time span of 1997 to 2019. According to AGREE Ⅱ, 5 were A-level guidelines, 18 were B-level guidelines, and 2 were C-level guidelines. Scope and purpose, rigour of development, clarity of presentations and editorial independence obtained high average scores (more than 60%) among all 25 guidelines. The average scores of guidelines in different domains of AGREE Ⅱ varied with regions and countries. Triptans and NSAIDs were the most frequently recommended as first-line drugs for the acute management; beta-blockers and antiepileptic drugs were recommended for the first-line prevention drugs of migraine in adults. There were 2 guidelines that recommended complementary treatments, one recommended traditional Chinese medicine and another recommended herbal butterbur.ConclusionsThe methodological quality of the pharmacological intervention guidelines of migraine in adults is suboptimal among different regions or countries. The quality of evidence-based guidelines is superior to that established by consensus. The consistency of first-line drug recommendations is strong, but there are still regional differences. The therapeutic effect of traditional Chinese medicine requires further verification.
The current issue of air pollution has pushed the development of the corresponding observational air pollution studies. The World Health Organization has developed a new risk of bias (RoB) assessment instrument and a related guideline for assessing the risk of potential bias in observational air pollution studies. This study introduced the background, methods, uses, advantages and disadvantages, precautions, and usage scenarios of the RoB instrument. It is expected to provide researchers with corresponding quality evaluation tools when writing related systematic review and meta-analysis, which will also help provide reporting standards for observational air pollution studies, thereby improving the quality of studies.
Objective We searched the Cochrane Library（Issue 3, 2005 ）to identity evidence related to palliative treatment. We found that Opioids are effective for the palliation of breathlessness in terminal illness. Oral Morphine and hydromorphone is effective for cancer pain. Radiotherapy and Bisphosphonates can relief pain secondary to bone metastases. Corticosteroids can resolve malignant bowel obstruction in advanced gynaecological and gastrointestinal cancer.
Objective To investigate the preparing procedures for the larger chemically acellular nerve allografts (CANA) and to establish an evaluation criteria and the preparation method.Methods The sciatic nerves ofthe dogs were exposed by a muscle-splitting incision and were isolated free of the underlying fascia. The 50-mm-long segments of the nerve were made. The proximal and distal ends of the nerve segments were labelled and stabilized by pinning the ends to a thin plastic support, and then they were treated according to the following decellularization processes: The nerve segments were rinsed with the distilled water for 9h, transferred in a 3% Triton-100 solution for 12 h, soaked in 7% sodium deoxycholate for 12 h, and washed in the distilled water for 6 h. All the decellularization steps were performed at room temperature. The nerve segments were divided into 5 subgroups. In Group Ⅰ, Group Ⅱ and Group Ⅲ, the nerve segments were decellularized for 2, 3 and 4 times, respectively. In Group Ⅳ and Group Ⅴ, the two ends of the nerve segments were ligated with a silk line and were decellularized for 2 and 3 times, respectively. Each nerve segment was subdivided into 5 portions from the proximal end to the distal end. The degrees of decellularization, activity of Laminin, degrees of demyelination, and integrity of the nerve fiber tube were observed under microscope and were assessed by a scoring system. Results In all the groups the activity of Laminin was present and the degrees of decellularization were complete. As for the demyelination of the nerve segments, the myelin sheath in Groups Ⅰ, Ⅱ and Ⅲ was partially preserved, but it completely disappeared in Groups Ⅳ and Ⅴ. The structure of the nerve fiber tube in Groups Ⅰ and Ⅳ was almost normal. The total score for the degrees of decellularization, demyelination, and structural integrity was the lowest in Group Ⅳ but the quality was the best. Conclusion The degrees of demyelination are not parallel to the times of decellularization processes. In the quality control of CANA, we should consider the following 4 factors: activity of Laminin, degrees of decellularization, demyelination, and structural integrity. For the larger CANA,ligation of the two ends of the nerve segments during the decellularization procedure may be a better method of ensuring the quality of the decellularization.
ObjectiveTo comprehensively analyze current status and progress of vagus nerve-preserving radical gastrectomy for gastric cancer at domestic and foreign. MethodRelevant literatures about vagus nerve-preserving radical gastrectomy at domestic and foreign since 1996 were collected and reviewed. ResultsVagus nerve-preserving radical gastrectomy for gastric cancer had been recognized by many scholars both at home and abroad, which had a higher operation safety and feasibility, could obviously reduce the occurrence of postoperative acute inflammation, maintain the stability of gastrointestinal function to the greatest extent, significantly reduce the incidence of postoperative complications such as gallbladder stone and diarrhea, improve the postoperative quality of life. ConclusionUnder premise of strictly controlling operation indications and ensuring curative effect, vagus nerve-preserving radical gastrectomy is of great significance to improve prognosis of patient with gastric cancer.
Objective To evaluate the methodological and reporting quality of clinical guidelines and consensus for adult AIDS. Methods Databases including PubMed, EMbase, Web of Science, CBM, WanFang Data and CNKI were electronically searched and major guideline websites such as GIN, NICE, NGC and Yimaitong were also searched to collect guidelines and consensus for adult AIDS from inception to December 2021. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. Four reviewers evaluated the methodological and reporting quality of the included guidelines and consensus by using AGREE Ⅱ and RIGHT, respectively. Results A total of 17 adult AIDS guidelines and consensus were included. The average scores of AGREE Ⅱ in various domains were 59.48% for scope and purpose, 37.17% for stakeholder involvement, 30.76% for rigor of development, 74.75% for clarity of presentation, 35.54% for applicability, and 50.49% for editorial independence. The items with the highest reporting rate among the RIGHT evaluation items were 1a, 1b and 1c (100.00%), followed by 3 and 4 (94.12%), 13a and 13b (88.24%), 7b and 11a (76.47%), and 5 (64.71%), and the remaining items were all reported below 60%. Results of subgroup analysis showed that the clarity of presentation, applicability and editorial independence of the guidelines for adult AIDS expressed in AGREE Ⅱ and the average score of RIGHT were higher than those of the consensuses for adult AIDS; the average scores of guidelines and consensuses based on evidence-based medicine in five domains of AGREE Ⅱ (scope and purpose, stakeholder involvement, rigor of development, clarity of presentation and applicability) and RIGHT were higher than those based on expert opinions or reviews. The foreign guidelines and consensus had higher average scores in the six domains of AGREE Ⅱ and the RIGHT score than the domestic guidelines. Conclusion The methodological quality and reporting quality of the published clinical guidelines and consensuses for adult AIDS is low; in particular, there is a certain gap between the national and international guidelines and consensuses. It is suggested that future guideline developers should refer to international standards, such as AGREE Ⅱ and RIGHT, formulate high-quality guidelines and promote their application to better regulate the diagnosis and treatment of adult AIDS.
Objective To assess the vision-related quality of life(VRQL) in patients with age-related maculopathy (AMD) and the related factors in Shanghai. Methods The VRQL of 105 patiens with AMD and 105 without (the control group) in Shanghai was investigated via Chinese-version low vision quality of life questionnaire. Resutls The Cronbach α coefficient of the questionnaire is 0.97 in the patients with AMD, whose scores of the various quality of life were significantly lower than those in the control group. The more the exudative defect happened, or the longer the disease course developed, the lower the sccores were. All the scores of the scales and the total questionnaire were significantly related to the better or worse monocular visual acuity. The better monocular visual acuity was the first independent risk factor affecting all aspects of VRQL in pateints with AMD. Conclusions Decreased visual acutiy may gradually impair the VRQL in patients with AMD. Chinese-version questionnaire of low vision quality of life can provide the general information of the VRQL in patients with AMD.(Chin J Ocul Fundus Dis，2004，20：303-306)
Objective To investigate the quality of the randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) integrated with western medicine for severe acute respiratory syndrome (SARS). Method All the randomized controlled trials of traditional Chinese medicine integrated with western medicine for SARS worldwide were gained by electronic searching and hand searching. The quality of the RCTs was analyzed by the quality grade evaluation used in Cochrane handbook.The sample size, the baseline data, the results indexes were also analyzed. Results Seven RCTs included 501 SARS cases were identified. The quality grade of one RCT is B, the other six RCTs were graded C. None pre-specified sample size. One RCT tested the differences of the baseline data by statistic method. One RCT reported quality of life as result index. None reported the adverse events.Conclusions Current RCTs of TCM integrated with western medicine can’t provide b evidence for clinical practice because of the poor quality.
