Journal of rehabilitation medicine. 2022;:jrm00312
Abstract
OBJECTIVE Partial-thickness rotator cuff tears have a high prevalence in older people. Treatment for such tears remains controversial. Platelet-rich plasma has recently attracted attention for treating partial-thickness rotator cuff tears, due to its regenerative characteristics. However, the results of application of platelet-rich plasma in non-operative treatments are unclear. The aim of this review is to evaluate the effects on shoulder function improvement and pain relief of platelet-rich plasma injection in partial-thickness rotator cuff tears, at different follow-up times (3-6 weeks, 8-12 weeks, and more than 24 weeks after treatment) compared with placebo or corticosteroids. DESIGN A systematic review and meta-analysis. METHODS Several databases, including PubMed, EMBASE, and Cochrane, were searched. Eleven studies met the inclusion criteria for the meta-analysis. The quality of research was evaluated using the Cochrane risk-of-bias tool. The effectiveness of platelet-rich plasma was calculated as the difference between baseline measurements and post-injection outcomes. The standardized mean difference was used to compare different outcome scales or questionnaire measurements. Statistical analysis was performed using Stata 15.0. RESULTS The analysis included 11 studies, with a total of 641 patients (318 treated with platelet-rich plasma and 323 controls). Compared with placebo, platelet-rich plasma exhibited significantly better effects on shoulder function improvement and pain relief at all 3 follow-up times. Compared with other conservative treatments, platelet-rich plasma exhibited significantly better effects on shoulder function and pain relief at 8-12 weeks and at more than 24 weeks after treatment. CONCLUSION This review showed positive effects on shoulder function improvement and pain relief of the use of platelet-rich plasma in treating partial-thickness rotator cuff tears, especially in relatively late stages of follow-up (more than 8 weeks) after treatment.

European geriatric medicine. 2021;12(1):5-15
Abstract
AIMS: To assess the efficacy and safety of iron supplementation for perioperative anemia in geriatric patients with hip fracture. METHODS A systematic search was conducted for studies published using PubMed, EMBASE and Cochrane Library Databases that compared iron supplementation with placebo in patients undergoing hip fracture surgery. The outcomes were blood transfusion rate and volume, length of stay, infection and mortality (last follow-up). Sub-group and sensitivity analyses were performed in cases of substantial heterogeneity. RESULTS The meta-analysis (6 studies: 1201 patients) indicated that iron supplements were not associated with reducing blood transfusion rate (OR 0.92, 95% CI 0.60-1.41; P = 0.69), but high heterogeneity (I(2) = 61%) was detected and a significant association was found in sensitivity analysis of four studies (n = 637; OR 0.68, 95% CI 0.49-0.95; P = 0.02). A significant reduction was detected in transfusion volume (two studies: n = 234; MD - 0.45 units/patient, 95% CI - 0.74 to - 0.16; P = 0.002), hospital stay (five studies: n = 998; MD - 1.42, 95% CI - 2.18 to - 0.67; P = 0.0002) and caused no increased risk of mortality (five studies: n = 937; OR 0.94, 95% CI 0.65-1.36; P = 0.76) and infection (four studies: n = 701; OR 0.58, 95% CI 0.38-0.90; P = 0.01). Sub-group analyses of four studies showed that the preoperative intravenous use of iron at 200-300 mg (two studies) may be the beneficial option for hip fractures patients. CONCLUSIONS Iron supplementation, especially preoperative intravenous use of 200-300 mg iron, is safe and associated with reducing transfusion requirement and hospital stay. Unfortunately, data were too limited to draw a definite conclusion. Further evaluation is required before recommending iron supplementation for older patients with hip fracture surgeries.

Public health. 2021;199:87-95
Abstract
OBJECTIVES Safe blood transfusion plays an important role in the prevention of transfusion-transmissible infections, and hepatitis C virus (HCV) infection is one of the major problems associated with this procedure. This meta-analysis aimed to determine the prevalence of HCV infection in Chinese blood donors. STUDY DESIGN The study design of this study is a meta-analysis. METHODS Eligible studies were retrieved from PubMed, Embase, China National Knowledge Infrastructure, China Science and Technology Journal Database and Wanfang literature databases from 2010 to 2020. The effect measure was presented as HCV prevalence with a 95% confidence interval (CI). Q test was used to assess the heterogeneity, and the I(2) statistics was determined to decide whether a random effects model or a fixed effects model should be used as the pooling method. Subgroup analyses were also conducted. RESULTS A total of 62 eligible studies, including 9,007,220 HCV blood donors, were analysed. Of the total blood donors, 35,017 were infected with HCV. The pooled HCV prevalence was 0.415% (95% CI: 0.371-0.458). The subgroup analysis revealed that the prevalence of positivity to anti-HCV antibodies was significantly different in each year (P < 0.05). However, no significant difference was observed in HCV prevalence in terms of sex. Moreover, the prevalence of positivity to anti-HCV was remarkably higher in first-time blood donors than in repeat blood donors (P < 0.05), and the rate of HCV infection among university students was significantly lower than that among soldiers (P < 0.05). CONCLUSIONS The rate of HCV infection showed a downward trend from 2010 to 2014, increased in 2015-2016, and finally decreased in 2017-2018. Thus, the prevalence of HCV infection has decreased in Chinese blood donors after comprehensive prevention and treatment.

Journal of the American Academy of Dermatology. 2020
Abstract
BACKGROUND Various systemic immunomodulating therapies (SITs) have been used to treat toxic epidermal necrolysis (TEN) but their efficacy remains unclear. OBJECTIVE To perform a systematic review and network meta-analysis (NMA) evaluating the effects of SITs on mortality for Stevens-Johnson syndrome (SJS)/TEN overlap and TEN. METHODS A literature search was performed in online databases (from inception to Oct 31, 2019). Outcomes were mortality rates and SCORe of Toxic Epidermal Necrolysis (SCORTEN)-based standardized mortality ratio (SMR). A frequentist random-effects model was adopted. RESULTS Sixty-seven studies involving 2079 patients were included. An NMA of 10 treatments revealed that none was superior to supportive care in reducing mortality rates and that thalidomide was associated with a significantly higher mortality rate (Odds ration [OR], 11.67; 95% confidence interval [CI], 1.42-95.96). For SMR, an NMA of 11 treatment arms demonstrated that corticosteroids and intravenous immunoglobulin (IVIg) combination therapy was the only treatment with significant survival benefits (SMR, 0.53; 95% CI, 0.31-0.93). LIMITATIONS Heterogeneity and a paucity of eligible randomized controlled trials. CONCLUSIONS Combination therapy with corticosteroids and IVIg may reduce mortality risks in patients with SJS/TEN overlap and TEN. Cyclosporine and etanercept are promising therapies but more studies are required to provide clearer evidence.

Blood Reviews. 2020;:100785
Abstract
The 2019 coronavirus disease (COVID-19) has become a global pandemic. Several studies report that ABO blood group polymorphism may be related to COVID-19 susceptibility and clinical outcomes; however, the results are controversial. We conducted a systematic review and meta-analysis to investigate whether ABO blood groups are associated with increased COVID-19 morbidity and mortality. A total of 715 articles were retrieved from seven databases. Ten articles were selected for meta-analysis after removal of duplicates and two levels of screenings. Overall, individuals with blood group A [odds ratio (OR) = 1.33, 95% confidence interval (CI) 1.14 to 1.56] and B (OR = 1.06, 95% CI 1.00 to 1.13) had a substantially higher risk of COVID-19, whereas this was not the case for blood group AB (OR = 1.07, 95% CI 0.88 to 1.30). Individuals with blood group O was not prone to develop the disease (OR = 0.71, 95% CI 0.60 to 0.84). Moreover, the risk of COVID-19 was significantly associated with the Rh-positive blood group (OR = 1.22, 95% CI 0.99 to 1.50). A meta-analysis of 5 studies suggested that blood group A was associated with a significantly increased risk of COVID-19 mortality (OR = 1.25, 95% CI 1.02 to 1.52). Mild publication bias was found in the included studies. This systematic review and meta-analysis indicated that blood groups A and B may be risk factors for COVID-19, whereas the blood group O appears to be protective. Blood group A may be related to unfavourable outcomes. Further rigorous and high-quality research evidence is needed to confirm this association.

Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease. Rebleeding is an independent predictor of unfavorable outcome after aneurysmal SAH. However, the accuracy of aneurysm size for predicting rebleeding after aneurysmal SAH is still unclear. Hence, we conducted this meta-analysis to evaluate the predictive accuracy of large aneurysm for rebleeding after SAH. METHODS We performed a literature search in PubMed and Embase. Original studies about aneurysm size and rebleeding after SAH were included. Two reviewers completed data extraction and quality assessment. Pooled sensitivity, specificity, and their 95% confidence intervals (CIs) of large aneurysm for predicting rebleeding were calculated and shown in a forest plot. The overall accuracy of large aneurysm for predicting rebleeding after SAH was shown using a summary receiver operating characteristic (SROC) curve. Publication bias were assessed using Deeks' funnel plot. RESULTS A total of ten studies with 3889 patients met eligibility criteria and were included in this meta-analysis. The pooled sensitivity and specificity of large aneurysm for predicting rebleeding were 0.39 (95% CI 0.25-0.56) and 0.75 (95% CI 0.67-0.82), respectively. The area under SROC curve was 0.67 (95% CI 0.62-0.71). Deeks' funnel plot did not show obvious publication bias among included studies in this meta-analysis. CONCLUSION The specificity of large aneurysm for predicting rebleeding after SAH is relatively high. However, its overall accuracy for predicting aneurysm rebleeding is not very satisfying. A comprehensive model should be developed to improve the accuracy of rebleeding prediction after SAH.

Aging. 2019;11
Abstract
BACKGROUND The role of human albumin infusion for the prevention and treatment of overt hepatic encephalopathy (HE) in liver cirrhosis remains unclear. RESULTS Among the 708 patients without pre-existing overt HE, albumin infusion significantly decreased the incidence of overt HE (4.20% versus 12.70%, P<0.001) and in-hospital mortality (1.70% versus 5.40%, P=0.008). Among the 182 patients with overt HE at admission or during hospitalization, albumin infusion significantly improved overt HE (84.60% versus 68.10%, P=0.009) and decreased in-hospital mortality (7.70% versus 19.80%, P=0.018). Meta-analysis of 6 studies found that albumin infusion might decrease the risk of overt HE (OR=1.63, P=0.07), but the difference was not statistically significant. Meta-analysis of 3 studies found that albumin infusion significantly improved overt HE (OR=2.40, P=0.04). CONCLUSIONS Based on the results of our retrospective study and meta-analysis, albumin infusion might prevent from the occurrence of overt HE and improve the severity of overt HE in cirrhosis. Our retrospective study also suggested that albumin infusion improved the outcomes of cirrhotic patients regardless of overt HE. METHODS Cirrhotic patients consecutively admitted between January 2010 and June 2014 were considered in a retrospective study. A 1:1 propensity score matching analysis was performed. Additionally, publications regarding albumin infusion for the management of overt HE were systematically searched. Meta-analyses were performed by random-effect model. Odds ratio (OR) was calculated.

Drug Design, Development and Therapy. 2018;12:3003-3011.
Abstract
Introduction: The purpose of this study was to analyze the effects of hypoxia-inducible factor (HIF) stabilizers on anemia in non-dialysis-dependent (NDD) and dialysis-dependent (DD) chronic kidney disease (CKD) patients. Methods: Published studies were extracted from PubMed, China Biological Medicine Database (CBM), Wanfang database, and Cochrane Library on March 10, 2018, and relevant studies were pooled and included in a meta-analysis. Data on hemoglobin (Hb), ferritin, and hepcidin levels, total iron-binding capacity (TIBC), and incidence of adverse events (AEs) were extracted and pooled using Review Manager Version 5.3. Results: Data from nine selected studies were extracted. Meta-analysis of the included studies showed that HIF stabilizers reduced ferritin and hepcidin levels and increased Hb level and TIBC in NDD-CKD patients. However, HIF stabilizers only increased TIBC, and did not affect ferritin, hepcidin, and Hb levels in DD-CKD patients. Furthermore, no notable differences in AEs and severe AEs between NDD-CKD and DD-CKD patients were detected. Conclusion: HIF stabilizers are effective for the treatment of anemia in NDD-CKD patients and safe for short-term use.

Li H, Bai L, Li Y, Fang Z
Medicine. 2018;97((45)):e12924.
Abstract
BACKGROUND Postoperative hemorrhage following total-knee arthroplasty (TKA) remains an important topic. The objective of the meta-analysis is to assess the effectiveness of oral antifibrinolytics for blood management in patients undergoing TKA. METHODS We searched Medline (1966 to August 2018), PubMed (1966 to August 2018), Embase (1980 to August 2018), ScienceDirect (1985 to August 2018), and the Web of Science (1995 to August 2018) for randomized control trials (RCTs). To assess the heterogeneity of study trial and determine the model for analysis (random-effect model or fixed-effect model), I tests and Chi-squared were conducted. We utilized the STATA 12.0 (StataCorp, College Station, TX) to perform all statistical analyses. RESULTS A total of 5 RCTs met our inclusion criteria. This meta-analysis shows that there are significant differences between the 2 groups regarding total blood loss, hemoglobin reduction, and transfusion rates. In addition, no adverse effects were identified in treatment groups. CONCLUSION The oral form of antifibrinolytics in TKA is able to significantly decrease blood loss, postoperative hemoglobin reduction, as well as transfusion requirements. No increased risk of postoperative complications was observed. Higher quality RCTs is necessary to confirm our finding.

Abstract
OBJECTIVE We aimed to analyze the efficacy and safety of romiplostim in the treatment of primary immune thrombocytopenia (ITP) in children. MATERIALS AND METHODS PubMed, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, Chinese biomedical literature database (CBM), Chinese Journal Full Text Database (CNKI), Wanfang and VIP database were searched. The bibliography was screened according to the inclusion and exclusion criteria and the target literature was selected. The data were extracted, and the quality of included literature was evaluated. RevMan 5.3 software was used to carry out the meta-analysis. The rate of effective, adverse and bleeding events was collected, and meta-analysis was performed. RESULTS 3 out of 43 papers met the inclusion criteria. Meta-analysis showed that there was a statistical significance in effective rate and median time to platelet rise to response criteria of in romiplostim group, RR=5.05, [95% CI (2.21, 11.53), p<0.01] and RR=9.67, [95% CI (1.89, 49.46), p<0.01]. Similar results occurred in the rate of adverse event and serious adverse event, [RR=0.95, 95% CI (0.69,1.31), p>0.05] and [RR=1.65, 95% CI (0.53,5.31), p>0.05]; bleeding event of the two groups was similar [RR=1.27, 95% CI (0.92,1.75), p>0.05]. CONCLUSIONS On the aspect of treating ITP, romiplostim is more effective and safer than placebo.
