BackgroundSo far, SARS-CoV-2 is the seventh coronavirus found to infect humans and cause disease with quite a strong infectivity. Patients diagnosed as severe or critical cases are prone to multiple organ dysfunction syndrome, acute respiratory distress syndrome and even death. Proinflammatory cytokine IL-6 has been reported to be associated with the severity of disease and mortality in patients with COVID-19.ObjectiveThis systematic review and meta-analysis were carried out to evaluate the association between IL-6 and severe disease and mortality in COVID-19 disease.MethodsA systematic literature search using China National Knowledge Infrastructure, Wanfang databases, China Science and Technology Journal Database, Chinese Biomedical Literature, Embase, PubMed and Cochrane Central Register of Controlled Trials was performed from inception until 16 January 2021.Results12 studies reported the value of IL-6 for predicting the severe disease in patients with COVID-19. The pooled area under the curve (AUC) was 0.85 (95% CI 0.821 to 0.931). 5 studies elaborated the predictive value of IL-6 on mortality. The pooled sensitivity, specificity and AUC were 0.15 (95% CI 0.13 to 0.17, I2=98.9%), 0.73 (95% CI 0.65 to 0.79, I2=91.8%) and 0.531 (95% CI 0.451 to 0.612), respectively. Meta-regression analysis showed that country, technique used, cut-off, sample, study design and detection time did not contribute to the heterogeneity of mortality.ConclusionIL-6 is an adequate predictor of severe disease in patients infected with the COVID-19. The finding of current study may guide clinicians and healthcare providers in identifying potentially severe or critical patients with COVID-19 at the initial stage of the disease. Moreover, we found that only monitoring IL-6 levels does not seem to predict mortality and was not associated with COVID-19’s mortality.PROSPERO registration numberCRD42021233649.

IntroductionThe recent viral pneumonia caused by the COVID-19 has gained the attention of the people all over the world. We aim to investigate the effects of respiratory rehabilitation therapy on patients infected with the novel coronavirus by conducting a systematic review and meta-analysis.Methods and analysisThis systematic review and meta-analysis have been registered in the International Prospective Register of Systematic Reviews (PROSPERO). The PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang Data and Viper information databases will be searched from inception time to date without restricting research types to find relevant studies. We will also look into reference lists of relevant trials and reviews, and manually search grey literature, such as trial registries. Two reviewers will independently extract data and perform quality assessment of included studies. Review Manager V.5.3 (Cochrane Collaboration) and Stata V.16.0 software will be used to conduct this meta-analysis. The mean difference or standardised mean difference with 95% CIs is used in the computation of continuous variables to synthesise data.Ethics and disseminationEthical approval is not required due to the nature of this meta-analysis, which is based on published papers. The results of this systematic review and meta-analysis will be published in a peer-reviewed journal once we finish this study.PROSPERO registration numberCRD42020180214.

IntroductionBiliary colic (BC) is a severe pain associated with nausea and vomiting, which is the most common symptom among the gallstone population. This protocol proposes a methodology for conducting a systematic review and meta-analysis that aims to assess the benefits and safety of acupuncture in patients with BC.Methods and analysisClinical trials will be identified through nine databases from inception to December 2020, using Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Allied and Complementary Medicine Database (AMED), CINAHL, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP Database and Wanfang Database. Search words will be used for the BC and acupuncture. The analysis would include randomised, controlled, clinical trials of adults with BC that were published in either Chinese or English. The primary outcome is to measure pain relief. Two or three reviewers should be in charge of study selection, data extraction and evaluating the risk of bias. RevMan software (V.5.4) will be used to perform the assessment of the risk of bias and data synthesis.Ethics and disseminationEthics approval will not be required for this review, as it will only involve the collection of literature previously published. The results of this meta-analysis will be disseminated in a peer-reviewed journal or relevant conference, through publication.Trial registration numberCRD42020167510.

AbstractCoronavirus disease 2019 (COVID-19), an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is responsible for the most threatening pandemic in modern history. The aim of this systematic review and meta-analysis was to investigate the associations between serum albumin concentrations and COVID-19 disease severity and adverse outcomes. A systematic literature search was conducted in PubMed, from inception to October 30, 2020. Sixty-seven studies in 19,760 COVID-19 patients (6141 with severe disease or poor outcome) were selected for analysis. Pooled results showed that serum albumin concentrations were significantly lower in patients with severe disease or poor outcome (standard mean difference, SMD: − 0.99 g/L; 95% CI, − 1.11 to − 0.88, p < 0.001). In multivariate meta-regression analysis, age (t =  − 2.13, p = 0.043), publication geographic area (t = 2.16, p = 0.040), white blood cell count (t =  − 2.77, p = 0.008) and C-reactive protein (t =  − 2.43, p = 0.019) were significant contributors of between-study variance. Therefore, lower serum albumin concentrations are significantly associated with disease severity and adverse outcomes in COVID-19 patients. The assessment of serum albumin concentrations might assist with early risk stratification and selection of appropriate care pathways in this group.

Abstract Background Postoperative cognitive dysfunction (POCD) is a common condition after general anesthesia (GA). Previous studies have reported that propofol can ameliorate the occurrence of such disorder. However, its results are still inconsistent. Therefore, this systematic review will assess the efficacy and safety of propofol on POCD after GA. Methods Literature sources will be sought from inception to the present in Cochrane Library, MEDLINE, EMBASE, PsycINFO, Web of Science, Scopus, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure for randomized controlled trials (RCTs) assessing the administration of propofol on POCD after GA. All searches will be carried out without limitations to language and publication status. Outcomes comprise of cognitive impairments changes, impairments in short-term memory, concentration, language comprehension, social integration, quality of life, and adverse events. Cochrane risk of bias tool will be utilized to assess study quality. We will evaluate the quality of evidence for each outcome using Grading of Recommendations Assessment, Development and Evaluation approach. A narrative synthesis or a meta-analysis will be undertaken as appropriate. Discussion This study will systematically and comprehensively search literature and integrate evidence on the efficacy and safety of propofol on POCD after GA. Our findings will be of interest to clinicians and health-related policy makers. Systematic review registration PROSPERO CRD42020164096

IntroductionBoth physical and mental disorders may be exacerbated in patients with COVID-19 due to the experience of receiving intensive care; undergoing prolonged mechanical ventilation, sedation, proning and paralysis. Pulmonary rehabilitation is aimed to improve dyspnoea, relieve anxiety and depression, reduce the incidence of related complications, as well as prevent and improve dysfunction. However, the impact of respiratory rehabilitation on discharged patients with COVID-19 is currently unclear, especially on patients who have been mechanically ventilated over 24 hours. Therefore, we aim to investigate the efficacy of respiratory rehabilitation programmes, initiated after discharge from the intensive care unit, on the physical and mental health and health-related quality of life in critical patients with COVID-19.Methods and analysisWe have registered the protocol on PROSPERO and in the process of drafting it, we strictly followed the checklist of Preferred Reporting Items for Systematic Review and Meta-Analysis Potocols. We will search the PubMed, EMBASE, Web of Science, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, WanFang, VIP information databases and Chinese Biomedical Literature Database. Additionally, ongoing trials in the WHO International Clinical Trials Registry Platform, ClinicalTrials.gov and ISRCTN registry will be searched as well. Studies in English or Chinese and from any country will be accepted regardless of study design. Two review authors will independently extract data and assess the quality of included studies. Continuous data are described as standard mean differences (SMDs) with 95% CIs. Dichotomous data from randomised controlled trials are described as risk ratio(RR) with 95% CIs; otherwise, it is described as odds ratio(OR) with 95% CIs. I2 and the Cochrane’s Q statistic will be used to conduct heterogeneity assessment. The quality of evidence of main outcomes will be evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation(GRADE) criteria. When included studies are sufficient, we will conduct subgroup analysis and sensitivity analysis; the publication bias will be statistically analysed using a funnel plot analysis and Egger’s test.Ethics and disseminationOur review, planning to include published studies, does not need the request to the ethical committee. The final results of this review will be published in a peer-reviewed journal after completion.Patient and public involvementNo patient involved.PROSPERO registration numberCRD42020186791.

Background and Purpose: Subarachnoid hemorrhage (SAH) is a severe disease characterized by sudden headache, loss of consciousness, or focal neurological deficits. Melatonin has been reported as a potential neuroprotective agent of SAH. It provides protective effects through the anti-inflammatory effects or the autophagy pathway. Our systematic review aims to evaluate the efficacy of melatonin administration on experimental SAH animals and offer support for the future clinical trial design of the melatonin treatment following SAH.Methods: The following online databases were searched for experimentally controlled studies of the effect of melatonin on SAH models: PubMed, Web of Knowledge, Embase, and China National Knowledge Infrastructure (all until March 2021). The melatonin effect on the brain water content (BWC) and neurological score (NS) were compared between the treatment and control groups using the standardized mean difference (SMD).Results: Our literature identified 160 possible articles, and most of them were excluded due to duplication (n = 69) and failure to meet the inclusion criteria (n = 56). After screening the remaining 35 articles in detail, we excluded half of them because of no relevant outcome measures (n = 16), no relevant interventions (n = 3), review articles (n = 1), duplicated publications (n = 1), and studies on humans or cells (n = 2). Finally, this systematic review contained 12 studies between 2008 and 2018. All studies were written in English except for one study in Chinese, and all of them showed the effect of melatonin on BWC and NS in SAH models.Conclusion: Our research shows that melatonin can significantly improve the behavior and pathological results of SAH animal models. However, due to the small number of studies included in this meta-analysis, the experimental design and experimental method limitations should be considered when interpreting the results. Significant clinical and animal studies are still required to evaluate whether melatonin can be used in the adjuvant treatment of clinical SAH patients.

Background. Depression is a debilitating comorbidity of heart failure (HF) that needs assessment and management. Along with mind-body exercise to deal with HF with depression, the use of TaiChi and/or Qigong practices (TQPs) has increased. Therefore, this systematic review assesses the effects of TQPs on depression among patients with HF. Methods. Randomized controlled trials (RCTs) that examined the effect of TQPs on depression in patients with HF were searched by five databases (PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, CINAHL, and China National Knowledge Infrastructure (CNKI)). With standardized mean difference (SMD) and 95% confidence intervals (95% CI), random-effects meta-analyses of the effect of TQPs on depressive symptoms were performed. Results. Of eight included RCTs, seven (481 patients) provided data for the meta-analysis. The pooling revealed that TQPs contribute to depression remission in HF (SMD −0.66; 95% CI −0.98 to −0.33, P < 0.0001 ; I2 = 64%). Its antidepressive effect was not influenced by intervention duration or exercise setting, but rather by ejection fraction subtype, depressive severity, and depression instruments. The beneficial effects were preserved when the study with the largest effect was removed. Conclusion. This study suggests that TQPs might be a good strategy for alleviating depressive symptoms in patients with HF. And rigorous-design RCTs, which focus on the identified research gaps, are needed to further establish the therapeutic effects of TQPs for depression in HF.

Abstract Cognitive behavioral therapy (CBT) has been shown to be effective to delay cognitive decline for family dementia caregivers (DCs). However, whether cognitive intervention could effectively reduce depression through internet, group, telephone, individual, unguided self-help and combined formats remains unclear. Pubmed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Central Register of Controlled Trials, Web of science, China National Knowledge Infrastructure database, Chinese Biomedical Literature database and Wan Fang database were systematically searched. A total of 34 studies were included in our analysis based on a series of rigorous screenings, which comprised 3577 DCs. We conducted a network meta-analysis (NMA) to evaluate the relative effects and rank probability of different CBT delivery formats. A series of analyses and assessments, such as the pairwise meta-analysis and the risk of bias, were performed concurrently. Compared with controls, internet, telephone, and individual showed the largest improvement on depressive symptoms, whereas the unguided self-help delivery format was less effective. Internet delivery formats had the highest probability among the five CBT delivery formats. Our study indicated that the internet might be the best delivery formats for reducing the depression of family DCs. The findings from our study may be useful for policy makers and service commissioners when they make choices among different CBT delivery formats.
