RESUMO
BACKGROUND: This study aimed to achieve expert consensus regarding key items to be addressed by non-clinical operators using computer-software integrated medical dispatch protocols to manage out-of-hours telephone triage (OOH-TT) services for calls involving older adults seeking non-urgent unplanned care across Belgium. METHODS: A three-part classic e-Delphi study was conducted. A purposive sample of experts specialized in out-of-hours unplanned care and/or older persons across Belgium were recruited as panelists. Eligibility criteria included experts with at least 2 years of relevant experience. Level of consensus was defined to be reached when at least 70% of the panelists agreed or disagreed regarding the value of each item proposed within a survey for the top 10 most frequently used protocols for triaging older adults. Responses were analyzed over several rounds until expert consensus was found. Descriptive and thematic analyses were used to aggregate responses. RESULTS: N = 12 panelists agreed that several important missing protocol topics were not covered by the existing OOH-TT service. They also agreed about the nature of use (for the top 10 most frequently used protocols) but justified that some modifications should be made to keywords, interrogation questions, degree of urgency and/or flowcharts used for the algorithms to help operators gain better comprehensive understanding patient profiles, medical habits and history, level of support from informal caregivers, known comorbidities and frailty status. Furthermore, panelists also stressed the importance of considering feasibility in implementing protocols within the real-world setting and prioritizing the right type of training for operators which can facilitate the delivery of high-quality triage. Overall, consensus was found for nine of the top 10 most frequently used protocols for triaging older adults with no consensus found for the protocol on triaging patients unwell for no apparent reason. CONCLUSION: Our findings show that overall, a combination of patient related factors must be addressed to provide high quality triage for adults seeking non-urgent unplanned care over the telephone (in addition to age). However, further elements such as appropriate operator training and feasibility of implementing more population-specific protocols must also be considered. This study presents a useful step towards identifying key items which must be targeted within the larger scope of providing non-urgent out-of-hours telephone triage services for older adults seeking non-urgent unplanned care.

INTRODUCTION: Micronutrients are clinically important in managing COVID-19, and numerous studies have been conducted, but inconsistent findings exist. OBJECTIVE: To explore the association between micronutrients and COVID-19. METHODS: PubMed, Web of Science, Embase, Cochrane Library and Scopus for study search on July 30, 2022 and October 15, 2022. Literature selection, data extraction and quality assessment were performed in a double-blinded, group discussion format. Meta-analysis with overlapping associations were reconsolidated using random effects models, and narrative evidence was performed in tabular presentations. RESULTS: 57 reviews and 57 latest original studies were included. 21 reviews and 53 original studies were of moderate to high quality. Vitamin D, vitamin B, zinc, selenium, and ferritin levels differed between patients and healthy people. Vitamin D and zinc deficiencies increased COVID-19 infection by 0.97-fold/0.39-fold and 1.53-fold. Vitamin D deficiency increased severity 0.86-fold, while low vitamin B and selenium levels reduced severity. Vitamin D and calcium deficiencies increased ICU admission by 1.09 and 4.09-fold. Vitamin D deficiency increased mechanical ventilation by 0.4-fold. Vitamin D, zinc, and calcium deficiencies increased COVID-19 mortality by 0.53-fold, 0.46-fold, and 5.99-fold, respectively. CONCLUSION: The associations between vitamin D, zinc, and calcium deficiencies and adverse evolution of COVID-19 were positive, while the association between vitamin C and COVID-19 was insignificant.REGISTRATION: PROSPERO CRD42022353953.
RESUMO
BACKGROUND: Postoperative delirium (POD) is a common postoperative complication associated with multiple adverse consequences on patient outcomes and higher medical expenses. Preoperative anxiety has been suggested as a possible precipitating factor for the development of POD. As such, we aimed to explore the association between preoperative anxiety and POD in older surgical patients. METHODS: Electronic databases including MEDLINE (via PubMed), EMBASE (via Embase.com), Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature (CINAHL Complete; via EBSCOhost) and clinical trial registries were systematically searched to identify prospective studies examining preoperative anxiety as a risk factor for POD in older surgical patients. We used Joanna Briggs Institute Critical Appraisal Checklist for Cohort Studies to assess the quality of included studies. The association between preoperative anxiety and POD was summarized with odds ratios (ORs) and 95% confidence intervals (CIs) using DerSimonian-Laird random-effects meta-analysis. RESULTS: Eleven studies were included (1691 participants; mean age ranging between 63.1-82.3 years). Five studies used a theoretical definition for preoperative anxiety, with the Anxiety subscale of Hospital Anxiety and Depression Scale (HADS-A) as the instrument being most often used. When using dichotomized measures and within the HADS-A subgroup analysis, preoperative anxiety was significantly associated with POD (OR = 2.17, 95%CI: 1.01-4.68, I2 = 54%, Tau2 = 0.4, n = 5; OR = 3.23, 95%CI: 1.70-6.13, I2 = 0, Tau2 = 0, n = 4; respectively). No association was observed when using continuous measurements (OR = 0.99, 95%CI: 0.93-1.05, I2 = 0, Tau2 = 0, n = 4), nor in the subgroup analysis of STAI-6 (six-item version of state scale of Spielberger State-Trait Anxiety Inventory, OR = 1.07, 95%CI: 0.93-1.24, I2 = 0, Tau2 = 0, n = 2). We found the overall quality of included studies to be moderate to good. CONCLUSIONS: An unclear association between preoperative anxiety and POD in older surgical patients was found in our study. Given the ambiguity in conceptualization and measurement instruments used for preoperative anxiety, more research is warranted in which a greater emphasis should be placed on how preoperative anxiety is operationalized and measured.

BACKGROUND: The traditional Billroth II and Roux-en-Y anastomosis after laparoscopic distal gastrectomy for gastric cancer are associated with bile reflux gastritis and roux stasis syndrome, respectively. The uncut Roux-en-Y gastrojejunostomy can decrease the incidence of these complications by blocking the entry of bile and pancreatic juice into the residual stomach and retaining the impulses originating from the duodenum. The purpose of the present study was to compare the short-term outcomes of uncut Roux-en-Y (URY) and Billroth II combined Braun (BB) anastomosis. METHODS: In this prospective, multi-center, two-arm randomized controlled trial, 124 patients with advanced distal gastric cancer were randomized into two groups: URY (n = 62) and BB (n = 62) groups. RESULTS: The mean gastric juice pH was significantly lower in the URY group compared with the BB group (3.94 ± 0.71 vs. 5.83 ± 0.91, P < 0.0001). The bile reflux gastritis at 3 months (P < 0.0001) and 6 months (P = 0.002) was significantly more frequent in the BB group. No recanalization occurred in the URY group, and no significant difference was found between the two groups in terms of mean operative time (P = 0.69), mean time to perform anastomosis (P = 0.86), mean estimated blood loss (P = 0.77), mean number of harvested lymph nodes (P = 0.90), time to first passage of flatus or defecation (P = 0.87), postoperative hospital stay (P = 0.83), and the incidence of postoperative complications (P = 0.70). CONCLUSIONS: URY anastomosis is associated with a significantly lower incidence of bile reflux gastritis and roux stasis syndrome compared with BB anastomosis.

BACKGROUND: As single-cell sequencing technology has been gradually introduced, it is essential to characterize global collaboration networks and map development trends over the past 20 years. OBJECTIVE: The aim of this paper was to illustrate collaboration in the field of single-cell sequencing methods and explore key topics and future directions. METHODS: Bibliometric analyses were conducted with CiteSpace and VOSviewer software on publications prior to November 2019 from the Web of Science Core Collection about single-cell sequencing methods. RESULTS: Ultimately, we identified 2489 records, which were published in 495 journals by 14,202 authors from 1970 institutes in 61 countries. There was a noticeable increase in publications in 2014. The United States and high-income countries in Europe contributed to most of the records included. Harvard University, Stanford University, Karolinska Institutes, Peking University, and the University of Washington were the biggest nodes in every cluster of the collaboration network, and SA Teichmann, JC Marioni, A Regev, and FC Tang were the top-producing authors. Keywords co-occurrence analysis suggested applications in immunology as a developing research trend. CONCLUSIONS: We concluded that the global collaboration network was unformed and that high-income countries contributed more to the rapidly growth of publications of single-cell sequencing technology. Furthermore, the application in immunology might be the next research hotspot and developmental direction.

BACKGROUND: Network meta-analysis (NMA) has been widely used in the field of medicine and health, but the research topics and development trends are still unclear. This study aimed to identify the cooperation of countries and institutes and explore the hot topics and future prospects in the field of NMA. METHODS: Data of publications were downloaded from the Web of Science Core Collection. We used CiteSpace V, HistCite 2.1, and Excel 2016 to analyze literature information, including years, journals, countries, institutes, authors, keywords, and co-cited references. RESULTS: NMA research developed gradually before 2010 and rapidly in the following years. 2846 NMA studies were published in 771 journals in six languages. The PLoS One (110, 3.9%) was the most productive journal, and N Engl J Med (5904 co-citations) was the most co-cited journal. The most productive country was the United States (889, 31%) and the most productive institute was the University of Bristol (113, 4.0%). The active collaborations were observed between developed countries and between productive institutes. Of the top 10 authors, four were from the UK, and among the top 10 co-cited authors, six were from the UK. Randomized evidence, oral anti-diabetic drugs, coronary artery bypass, certolizumab pegol, non-valvular atrial fibrillation, and second-line antihyperglycemic therapy were the hot topics in this field. CONCLUSIONS: NMA studies have significantly increased over the past decade, especially from 2015 to 2017. Compared with developing countries, developed countries have contributed more to these publications and have closer cooperation, indicating that cooperation between developed and developing countries should be further strengthened. The treatment of diabetes, cardiovascular diseases, and immune rheumatism are the main hot topics.

This study aimed to analyze the methodological quality of systematic reviews of Shuxuening Injection and evaluate the efficacy and adverse reactions of Shuxuening Injection in the treatment of different diseases,in order to provide supportive evidence for clinical practice. Three Chinese databases and three English databases were retrieved to identify systematic reviews and Meta-analysis on the efficacy and safety of Shuxuening Injection in the treatment of diseases. The AMSTAR 2( a measurement tool to assess systematic reviews 2) tool was used to evaluate the methodological quality of the included systematic reviews,and tables were created to present the results of Meta-analyses. Twenty-four systematic reviews were included,all with very low methodological quality. Among the 16 AMSTAR-2 items,only 5 items had a compliance rate greater than 60. 0%,and 8 items had a compliance rate less than 50. 0%. For patients with cerebral infarction,Shuxuening Injection combined with conventional treatment was more effective than conventional treatment alone in terms of clinical efficiency and neurological deficit improvement. For patients with angina pectoris,Shuxuening Injection was superior to Danshen/Compound Danshen Injection in terms of the total effective rate of angina pectoris and total effective rate of ECG. The efficacy of Shuxuening Injection combined with conventional treatment is significantly better than conventional treatment.Shuxuening Injection( alone or combined with conventional treatments) was better than conventional treatments for cerebral hemorrhage,ischemic cerebrovascular disease,chronic pulmonary heart disease,vertigo and sudden deafness. Shuxuening Injection had better efficacy and lower incidence of adverse reactions,but the methodological quality of included systematic reviews was low. The results of this study still need to be verified by high-quality systematic reviews.

Qingkailing Injection is one of the most commonly used traditional Chinese medicine injections with significant clinical application for the treatment of multiple diseases. This study aims to analyze the systematic reviews( SRs) of Qingkailing Injection,in order to provide reference for the clinical application of Qingkailing Injection and the development of relevant clinical practice guidelines. We searched CNKI,CBM,Wanfang,VIP,Pub Med,Cochrane Library and EMbase to collect SRs from the time of database establishment to August 2020. The eligible SRs were included according to the inclusion and exclusion criteria. AMSTAR 2 was used to assess the methodological quality. The diseases,drugs in combinations and results were extracted and analyzed. A total of 24 SRs were selected,including 10 for the treatment of acute cerebrovascular diseases,9 for respiratory infections,2 for viral hepatitis,1 for chronic obstructive pulmonary disease,and two for the adverse effects of Qingkailing Injection. Only three entries of AMSTAR 2 item were fully reported by over 70%,and the rest were reported by less than 70%,with no report about item 2,3 and 10. Twenty-nine outcome indicators were correlated with the included SRs,of which three mostly frequent outcomes were effectiveness,adverse reaction,and neurological deficit scores,showing a good efficacy of Qingkailing Injection. The common severe adverse reaction was anaphylaxis,and mild adverse reactions were skin and mucous membrane reactions. The most frequently combined drug was antibiotics,mainly Penicillin and Penicillin+Pioneeromycin. The existing evidences showed that the methodological quality of SRs of Qingkailing Injection needed to be improved and Qingkailing Injection had an obvious efficacy. However,the selection of outcome indicators for clinical trials and SRs shall be standardized,and the reporting of basic information,such as drug combination,shall be strengthened to provide more powerful clinical services.

BACKGROUND: Network meta-analyses using individual participant data (IPD-NMAs) have been increasingly used to compare the effects of multiple interventions. Although there have been many studies on statistical methods for IPD-NMAs, it is unclear whether there are statistical defects in published IPD-NMAs and whether the reporting of statistical analyses has improved. This study aimed to investigate statistical methods used and assess the reporting and methodological quality of IPD-NMAs. METHODS: We searched four bibliographic databases to identify published IPD-NMAs. The methodological quality was assessed using AMSTAR-2 and reporting quality assessed based on PRISMA-IPD and PRISMA-NMA. We performed stratified analyses and correlation analyses to explore the factors that might affect quality. RESULTS: We identified 21 IPD-NMAs. Only 23.8% of the included IPD-NMAs reported statistical techniques used for missing participant data, 42.9% assessed the consistency, and none assessed the transitivity. None of the included IPD-NMAs reported sources of funding for trials included, only 9.5% stated pre-registration of protocols, and 28.6% assessed the risk of bias in individual studies. For reporting quality, compliance rates were lower than 50.0% for more than half of the items. Less than 15.0% of the IPD-NMAs reported data integrity, presented the network geometry, or clarified risk of bias across studies. IPD-NMAs with statistical or epidemiological authors often better assessed the inconsistency (P = 0.017). IPD-NMAs with a priori protocol were associated with higher reporting quality in terms of search (P = 0.046), data collection process (P = 0.031), and syntheses of results (P = 0.006). CONCLUSIONS: The reporting of statistical methods and compliance rates of methodological and reporting items of IPD-NMAs were suboptimal. Authors of future IPD-NMAs should address the identified flaws and strictly adhere to methodological and reporting guidelines.

Corona virus disease (COVID-19) has now spread to all parts of the world and almost all countries are battling against it. This study aimed to assess the efficacy and safety of Integrated Traditional Chinese and Western Medicine (Hereinafter referred to as "Integrated Medicine") to COVID-19. We searched six major Chinese and English databases to identify randomized controlled trials (RCTs) and case-control studies (CCSs) of Integrated Medicine on COVID-19. Two reviewers independently screened, identified studies, and extracted data. Cochrane Risk of Bias tool and the Newcastle-Ottawa Scale were used to assess the quality of included RCTs and CCSs, respectively. Stata (version 13.0; StataCorp) was used to perform meta-analyses with the random-effects model. Risk ratio (RR) was used for dichotomous data while the weighted mean difference (WMD) was adopted for continuous variables as effect size, both of which were demonstrated in effect size and 95% confidence intervals (CI). A total of 11 studies were included. Four were RCTs and seven were CCSs. The sample size of including studies ranged from 42 to 200 (total 982). The traditional Chinese medicine included Chinese medicine compound drugs (QingFei TouXie FuZhengFang) and Chinese patent medicine (e.g. Shufeng Jiedu Capsule, Lianhua Qingwen granules). Compared with the control group, the overall response rate [RRâ¯=â¯1.230, 95%CI (1.113, 1.359), Pâ¯=â¯0.000], cure rate [RRâ¯=â¯1.604, 95%CI (1.181, 2.177), Pâ¯=â¯0.002], severity illness rate [RRâ¯=â¯0.350, 95%CI (0.154, 0.792), Pâ¯=â¯0.012], and hospital stay [WMDâ¯=â¯-1.991, 95%CI (-3.278, -0.703), Pâ¯=â¯0.002] of the intervention group were better. In addition, Integrated Medicine can improve the disappearance rate of fever, cough, expectoration, fatigue, chest tightness and anorexia and reduce patients' fever, and fatigue time (Pâ¯<â¯0.05). This review found that Integrated Medicine had better effects and did not increase adverse drug reactions for COVID-19. More high-quality RCTs are needed in the future.

Coronavirus disease 2019(COVID-19) is a newly emerged and highly contagious respiratory disease. Traditional Chinese medicine(TCM) has both systematism theory knowledge and clinical practical value in the prevention and treatment of COVID-19. Therefore, it was particularly important to examine the effect of TCM in the prevention and treatment of COVID-19. The patents of TCM might reflect the latest progression of scientific research. We aimed to provide reference for the prevention and treatment of COVID-19 by extracting and analyzing the TCM patents from the Patent Information Sharing Platform of COVID-19. The antiviral TCM patents were screened and exported from the Patent Information Sharing Platform. VOSviewer 1.6.14 was used to visualize and analyze the network of TCM in these patents. There were total 292 TCM patents, including 52 patents for etiological treatment and 240 patents for symptomatic treatment. Thirty-two provinces and 1 076 inventors were involved, mainly from Beijing, Guangdong and Jiangsu. Overall, there were 356 TCMs, 71 single prescriptions, and 221 compound prescriptions. The patents for treatment of coronavirus mainly focused on the treatment of coronavirus, while the patents for symptomatic treatment mainly focuses on the improvement of respiratory symptoms, such as fever and cough. There were 14 highly frequently used TCMs, including Glycyrrhizae Radix et Rhizoma, Scutellariae Radix, Lonicerae Japonicae Flos, Forsythiae Fructus, Isatidis Radix, Astragali Radix, Menthae Haplocalycis Herba, Gypsum Fibrosum, Houttuyniae Herba, Isatidis Folium, Rhei Radix et Rhizoma, Gardeniae Fructus, Platycodonis Radix, Armeniacae Semen Amarum. The analyzed results of the TCM patents from the patent information sharing platform of COVID-19 were consistent with the Guideline of Diagnosis and Treatment of COVID-19(7th edition), and the combination of TCM in each cluster may also provide future directions for drug compatibility.

Japanese encephalitis virus (JEV) is a zoonotic pathogen transmitted by Culex mosquitoes and is the leading cause of viral encephalitis in humans. JEV infection of swine, which are the main amplifying hosts for JEV, can cause reproductive failure in sows; in boars it can cause testitis and infertility. The prevalence of JEV in swine is a continuous threat to human health. A practical diagnostic method for monitoring JEV infection in swine herds is essential for control of the disease in both swine and humans. Here, we have identified a high-affinity anti-JEV NS1 monoclonal antibody (mAb) by indirect ELISA and utilized it for the development of a blocking ELISA (bELISA). The optimal NS1 protein coating concentration (2 µg/mL) and mAb working concentration (1 µg/mL) were determined by checkerboard titration. One hundred ten JEV-antibody-negative serum samples were used to establish 34.03% inhibition as the cutoff value for a negative result. By the bELISA, seroconversion in 80% of newly JEV-vaccinated pigs was detected by 7 days post-immunization, while by the commercial envelope-protein-based iELISA, seroconversion was detected in 20% of the newly vaccinated pigs. We found 98.7% agreement between the bELISA and the commercial iELISA when we tested 157 field samples using both methods. From an epidemiological survey of swine serum collected between 2014 and 2016, we found that the average JEV seropositive rate in unvaccinated commodity pigs was 8.1%, and in vaccinated boars and sows, it was 67.6%.

CONTEXT: The optimal duration of antibiotic treatment of children with community-acquired pneumonia (CAP) remains unclear. OBJECTIVES: This study aimed to compare the efficacy and safety of shorter versus longer duration of antibiotic treatment of children with CAP. DATA SOURCES: We searched Medline, Embase, CENTRAL, and CINAHL. STUDY SELECTION: Randomized clinical trials comparing shorter (≤5 days) with longer duration antibiotic treatments in children with CAP. DATA EXTRACTION: Paired reviewers independently extracted data and we performed random-effects meta-analyses to summarize the evidence. RESULTS: Sixteen trials with 12 774 patients, treated as outpatients with oral antibiotics, proved eligible. There are probably no substantial differences between shorter-duration and longer-duration antibiotics in clinical cure (odds ratio 1.01, 95% confidence interval [CI] 0.87 to 1.17; risk difference [RD] 0.1%; moderate certainty), treatment failure (relative risk [RR] 1.06, 95% CI 0.93 to 1.21; RD 0.3%; moderate certainty), and relapse (RR 1.12, 95% CI 0.92 to 1.35; RD 0.5%; moderate certainty). Compared with longer-duration antibiotics, shorter-duration antibiotics do not appreciably increase mortality (RD 0.0%, 95% CI -0.2 to 0.1; high certainty), and probably have little or no impact on the need for change in antibiotics (RR 1.03, 95% CI 0.72 to 1.47; RD 0.2%; moderate certainty), need for hospitalization (RD -0.2%, 95% CI -0.9 to 0.5; moderate certainty), and severe adverse events (RD 0.0%, 95% CI -0.2 to 0.2; moderate certainty). LIMITATIONS: For some outcomes, evidence was lacking. CONCLUSIONS: Duration of antibiotic therapy likely makes no important difference in patient-important outcomes. Healthcare workers should prioritize the use of shorter-duration antibiotics for children with CAP treated as outpatients with oral antibiotics.

Importance: Alopecia areata (AA) is a common chronic tissue-specific autoimmune disease. Several studies have reported outcomes of Janus kinase (JAK) inhibitors for treating AA, but limited evidence has emerged. Objective: To evaluate the effectiveness and safety associated with JAK inhibitors for AA. Data Sources: MEDLINE, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched from inception until August 2022. Study Selection: Only randomized clinical trials (RCTs) were included. Pairs of reviewers independently and in duplicate selected the studies. Data Extraction and Synthesis: Hartung-Knapp-Sidik-Jonkman random-effects models were used for meta-analysis. Certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. This study is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Main Outcomes and Measures: The primary outcomes of interest were (1) proportion of patients who achieved 30%, 50%, and 90% improvement in Severity of Alopecia Tool (SALT) score from baseline, (2) change from baseline SALT score, and (3) treatment-related adverse event (AE). Results: Seven RCTs with 1710 patients (1083 females [63.3%]; mean [SD] age range, 36.3 [10.4] to 69.7 [16.2] years) were eligible and included in the study. JAK inhibitors were associated with more patients achieving 50% improvement (odds ratio [OR], 5.28 [95% CI, 1.69-16.46]; GRADE assessment: low certainty) and 90% improvement (OR, 8.15 [95% CI, 4.42-15.03]; GRADE assessment: low certainty) in SALT score from baseline compared with placebo. JAK inhibitors were associated with more lowered SALT scores from the baseline compared with placebo (mean difference [MD], -34.52 [95% CI, -37.80 to -31.24]; GRADE assessment: moderate certainty), and JAK inhibitors were not associated with more treatment-related AEs (relative risk [RR], 1.25 [95% CI, 1.00-1.57]; GRADE assessment: high certainty) compared with placebo. High certainty of evidence showed that JAK inhibitors may not be associated with more severe AEs compared with placebo (RR, 0.77; 95% CI, 0.41-1.43). The subgroup analysis showed that oral JAK inhibitors were more efficient than placebo (change from baseline SALT scores: MD, -36.80; 95% CI, -39.57 to -34.02), and no difference was found between external JAK inhibitors and placebo (change from baseline SALT scores: MD, -0.40; 95% CI, -11.30 to 10.50). Conclusions and Relevance: Results of this systematic review and meta-analysis suggest that JAK inhibitors, compared with placebo, were associated with hair regrowth and that the outcome of oral JAK inhibitors was better than the external route of administration. Although the safety and tolerability of JAK inhibitors were acceptable, longer RCTs are needed to further assess the effectiveness and safety of these treatments for AA.

OBJECTIVES: This study aimed to assess the reporting quality and risk of bias of Cochrane individual participant data meta-analyses (IPD-MAs). METHODS: We searched the Cochrane Library and identified the Cochrane IPD-MAs. We used the Preferred Reporting Items for Systematic Review and Meta-Analyses of individual participant data (PRISMA-IPD) assessed the reporting quality of included Cochrane IPD- MAs, and the Risk Of Bias In Systematic reviews (ROBIS) tool was used to assess the risk of bias. We performed stratified and correlation analyses to explore factors affecting the quality. RESULTS: Forty-six Cochrane IPD-MAs were included in our study. Twenty-six Cochrane IPD-MAs (56.5%) had statistical or epidemiological authors involved, and 31 (67.4%) contained only IPD data. Thirty-five studies (76.1%) did not report whether they used 1-stage or 2-stage methods, and forty (87.0%) did not report the statistical techniques used for missing participant data. We found that the entire compliance reported PRISMA-IPD items of Cochrane IPD-MAs published after 2015 (n = 18; Mean ± SD: 26.61 ± 2.75) was higher than those studies published in 2015 and before (n = 28; Mean ± SD: 22.61 ± 4.73), the difference was statistically significant (p = 0.002). A strong positive correlation was found between the fully reported PRISMA-IPD items and fully accordance ROBIS items (Spearman's: ρ = 0.653, p < 0.001). CONCLUSIONS: The quality of Cochrane IPD-MAs is not high, especially in the reporting of statistical methods. There was room for further improvement in IPD retrieval, IPD integrity and statistical analyses.

INTRODUCTION: Gastroesophageal reflux disease (GERD) is a highly prevalent gastrointestinal disorder that causes diverse esophageal and extraesophageal symptoms. Many clinical practice guidelines (CPGs) have been issued around the world to provide practical evidence regarding GERD management. However, some of the recommendations discussed in various CPGs are inconsistent across individual documents. OBJECTIVES: We aimed to summarize the evidence from CPGs on GERD and assess the consistency of the recommendations. PATIENTS AND METHODS: In this scoping review, we identified current CPGs on the clinical management of GERD, which were comprehensively searched for in electronic databases and on relevant scientific websites. The recommendations were extracted using the populationinterventioncomparison framework and were subsequently categorized into tables. RESULTS: Ultimately, 24 CPGs were identified. They included 86 recommendations, which were classified into 5 categories: definition, epidemiology, diagnosis, treatment, and complications. Among the identified recommendations, 68 were proposed in at least 2 CPGs, and they were assessed for the consistency of direction and strength. Overall, 32.4% of the recommendations (22/68) were consistent in direction and strength, whereas 60.3% (41/68) were consistent in direction but inconsistent in strength. Moreover, 7.4% (5/68) were inconsistent in direction. These referred to the relationship between GERD and tobacco consumption, Helicobacter pylori infection, diagnostic utility of the 2week proton pump inhibitor test, cessation of special food, and antireflux surgery for GERD with extraesophageal symptoms. CONCLUSIONS: Most CPG recommendations regarding GERD were consistent in direction, except for 5 discrepancies, for which further welldesigned, largescale research is required to explain the inconsistency.

INTRODUCTION: Rectal cancer is one of the top 10 cancers worldwide. Up to 80% of patients with rectal tumours have had sphincter-saving surgery, mainly due to the large expectation of anal preservation. However, patients tend to experience low anterior resection syndrome (LARS) after rectal resection, which is disordered bowel function that includes faecal incontinence, urgency, frequent defecation, constipation and evacuation difficulties. LARS, with an estimated prevalence of 41%, has been reported to substantially decrease the quality of life of patients. However, no comprehensive preventive strategies are currently available for LARS. This systematic review aims to synthesise evidence on the current LARS preventive strategies. METHODS AND ANALYSIS: This protocol is reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) checklist. Literature in PubMed (via Medline), Embase and the Cochrane Library from inception to July 2023 will be searched to identify articles relevant to preventive effectiveness against LARS. The Cochrane Collaboration's risk of bias tool for randomised controlled trials and the Newcastle-Ottawa Scale for clinical controlled trials, cohort studies and case-control studies will be used to assess the risk of bias. We will group the included studies by the type of LARS prevention strategy and present an overview of the main findings in the form of evidence mapping. A meta-analysis is planned if there is no substantial clinical heterogeneity between the included studies. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) will be used to evaluate the quality of the evidence. ETHICS AND DISSEMINATION: Ethical approval is not needed for systematic review of published data. The findings will be published in a peer-reviewed journal and disseminated at scientific conferences. PROSPERO REGISTRATION NUMBER: CRD42023402886.

BACKGROUND: Pharmacological treatment is common in practice and widely used for the management of insomnia. However, evidence comparing the relative effectiveness, safety, and certainty of evidence among drug classes and individual drugs for insomnia are still lacking. This study aimed to determine the relative effectiveness, safety, and tolerability of drugs for insomnia. METHODS: In this systematic review and network meta-analysis we systematically searched PubMed, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, and ClinicalTrials.gov, from inception to January 10, 2022 to identify randomized controlled trials that compared insomnia drugs with placebo or an active comparator in adults with insomnia. We conducted random-effects frequentist network meta-analyses to summarize the evidence, and used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the certainty, categorize interventionsand present the findings. RESULTS: A total of 148 articles met our eligibility criteria; these included 153 trials which enrolled 46,412 participants and assessed 36 individual drugs from eight drug classes. Compared with placebo, both subjectively and objectively measured total sleep time were significantly improved with non-benzodiazepine (subjective: mean difference [MD] 25.07, 95% confidence interval [CI] 15.49-34.64, low certainty; objective: MD 22.34, 95% CI 7.64-37.05, high certainty), antidepressants (subjective: MD 54.40, 95% CI 34.96-75.83, low certainty; objective: MD 35.64, 95% CI 13.05-58.24, high certainty), and orexin receptor antagonists (subjective: MD 21.62, 95% CI 0.84-42.40, high certainty; objective: MD 31.81, 95% CI 2.66-60.95, high certainty); of which doxepin, almorexant, suvorexant, and lemborexant were among the relatively effective drugs with relatively good tolerability and lower risks of any adverse events (AEs). Both subjectively and objectively measured sleep onset latency were significantly shortened with non-benzodiazepines (subjective: MD - 10.12, 95% CI - 13.84 to - 6.40, moderate certainty; objective: MD - 12.11, 95% CI - 19.31 to - 4.90, moderate certainty) and melatonin receptor agonists (subjective: MD - 7.73, 95% CI - 15.21 to - 0.26, high certainty; objective: MD - 7.04, 95% CI - 12.12 to - 1.95, moderate certainty); in particular, zopiclone was among the most effective drugs with a lower risk of any AEs but worse tolerability. Non-benzodiazepines could significantly decrease both subjective and objective measured wake time after sleep onset (subjective: MD - 16.67, 95% CI - 21.79 to - 11.56, moderate certainty; objective: MD - 13.92, 95% CI - 22.71 to - 5.14, moderate certainty). CONCLUSIONS: Non-benzodiazepines probably improve total sleep time, sleep onset latency, and wake time after sleep onset. Other insomnia drug classes and individual drugs also showed potential benefits in improving insomnia symptoms. However, the choice of insomnia drugs should be based on the phenotype of insomnia presented, as well as each drug's safety and tolerability. Protocol registration PROSPERO (CRD42019138790).

Lianhua Qingwen combined with Western medicine (LHQW+WM) has been proposed as a viable treatment for coronavirus disease 2019 (COVID-19). Interestingly, umbrella reviews of systematic reviews (SRs), which provide the most comprehensive evidence, are the best evidence in evidence-based medicine. Therefore, an umbrella review of SRs that summarizes and evaluates the efficacy of LHQW+WM for COVID-19 is urgently required. Methods: Overall, 6 databases were used to conduct a comprehensive literature search from inception to January 22, 2022. The corrected covered area (CCA) was used to analyze the overlapping between SRs. Meta-analysis was conducted when that of the included SRs was inappropriate. A MeaSurement Tool to Assess Systematic Reviews (AMSTAR-2) was also employed to assess the quality of the included SRs. Results: In total, 12 SRs were identified, which included 12 unique primary studies. The included SRs ranged in quality from moderate to critically low and had an extremely high CCA (36.4%). Compared to conventional treatment, LHQW+WM showed efficacy concerning fatigue recovery [risk ratio (RR) = 1.69, 95% confidence interval (CI): 1.04-2.73, n = 2, I2 = 0%], cough recovery (RR = 1.65, 95% CI: 1.09-2.51, n = 3, I2 = 39.1%), and overall effective rates (RR = 1.17, 95% CI: 1.07-1.28, n = 3, I2 = 17.5%). Conclusion: LHQW+WM may improve the clinical symptoms of patients with COVID-19; however, the results should be interpreted cautiously because of the rigorous processes in the included SRs.
