Abstract
PURPOSE Extracorporeal membrane oxygenation (ECMO) is employed to support critically ill COVD-19 patients. The occurrence of ischemic stroke and intracranial hemorrhage (ICH), as well as the implementation of anticoagulation strategies under the dual influence of ECMO and COVID-19 remain unclear. We conducted a systematic review and meta-analysis to describe the ischemic stroke, ICH and overall in-hospital mortality in COVID-19 patients receiving ECMO and summarize the anticoagulation regimens. METHODS EMBASE, PubMed, Cochrane, and Scopus were searched for studies examining ischemic stroke, ICH, and mortality in COVID-19 patients supported with ECMO. The outcomes were incidences of ischemic stroke, ICH, overall in-hospital mortality and anticoagulation regimens. We calculated the pooled proportions and 95% confidence intervals (CIs) to summarize the results. RESULTS We analyzed 12 peer-reviewed studies involving 6039 COVID-19 patients. The incidence of ischemic stroke had a pooled estimate of 2.2% (95% CI: 1.2%-3.2%). The pooled prevalence of ICH was 8.0% (95% CI: 6.3%-9.6%). The pooled estimate of overall in-hospital mortality was 40.3% (95% CI: 33.1%-47.5%). The occurrence of ICH was significantly higher in COVID-19 patients supported with ECMO than in other respiratory ECMO [relative risk=1.75 (95% CI: 1.00-3.07)]. Unfractionated heparin was the most commonly used anticoagulant, and anticoagulation monitoring practice varied among centers. CONCLUSIONS Ischemic stroke and ICH were common under the double "hit" of COVID-19 and ECMO. The prevalence of ICH was significantly higher in COVID-19 patients supported with ECMO than non-COVID-19 patients requiring ECMO. Individualized anticoagulation regimens may be a good choice to balance thrombosis and bleeding. More detailed research and further exploration are needed to clarify the underlying mechanism and clinical management decisions.

BMJ open. 2022;12(11):e061008
Abstract
OBJECTIVES The purpose of this meta-analysis was to investigate the efficacy and safety of mesenchymal stem cells (MSCs) combined with platelet-rich plasma (PRP) in the treatment of knee osteoarthritis (KOA). DESIGN Systematic review and meta-analysis. PARTICIPANTS Patients with KOA. INTERVENTIONS Use of MSCs+PRP. PRIMARY AND SECONDARY OUTCOMES Visual Analogue Scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS) and adverse reactions. DATA SOURCES PubMed, Cochrane Library, Embase and China National Knowledge Infrastructure were searched from inception to 15 July 2021. MEASURES The OR or weighted mean difference (WMD) of relevant outcome indicators was calculated. Study quality was evaluated using the risk-of-bias assessment tool version 2.0. Heterogeneity among studies was evaluated by calculating I(2). If I(2)<50%, a fixed-effect model was applied; conversely, if I(2) ≥50%, a random-effect model was applied. RESULTS Six controlled clinical trials with 493 cases were included. The meta-analysis results showed that in terms of the VAS score 3 months after treatment, MSCs+PRP had no significant effect on the reduction of the VAS score in patients with KOA compared with the control (p=0.09), hyaluronic acid (HA) (p=0.15) or PRP alone (p=0.07). MSCs+PRP was more effective in reducing the VAS score at 6 and 12 months after treatment than the control (WMD=-0.55, 95% CI -0.87 to -0.22, p<0.001), HA (WMD=-1.20, 95% CI -2.28 to -0.13, p=0.03) or PRP alone (WMD=-0.54, 95% CI -0.89 to -0.18, p=0.003). Regarding the decrease in the total WOMAC score at 3 and 6 months after treatment, MSCs+PRP showed better clinical efficacy than the control or HA alone (p<0.01). Compared with the control, MSCs+PRP exhibited no significant difference in reducing the total WOMAC score 12 months after treatment (p=0.39). There was no significant difference between MSCs+PRP and the control in terms of improvement of the KOOS 12 months after treatment (p=0.16). Compared with MSCs alone, MSCs+PRP exhibited no significant difference in the incidence of adverse reactions (p=0.22) 12 months after treatment. CONCLUSIONS Treatment with MSCs+PRP showed good clinical efficacy in improving pain and joint function in patients with KOA. Compared with MSCs alone, there was no significant difference in the incidence of adverse reactions with MSCs+PRP. PROSPERO REGISTRATION NUMBER CRD 42021275830.

Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association. 2021
Abstract
PURPOSE To perform a network meta-analysis to evaluate clinical efficacy and treatment related adverse events (AEs) of intra-articular hyaluronic acid (HA), leukocyte-poor platelet-rich plasma (LP-PRP), leukocyte-rich platelet-rich plasma (LR-PRP), bone marrow mesenchymal stem cells (BM-MSCs), adipose mesenchymal stem cells (AD-MSCs) and saline (placebo) during 6 and 12 months of follow-up. METHODS Six databases were searched for randomized controlled trials. Outcome assessment included the visual analog scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis (WOMAC) pain subscore, WOMAC score, International Knee Documentation Committee (IKDC) subjective score, and treatment-related AEs. Main inclusion criteria were at least one of the aforementioned outcome measurements, a minimum follow-up period of 5 months, and >80% patient follow-up. Treatments combined with the use of other operations or drugs were excluded. RESULTS Forty-three studies meeting the eligibility criteria were included. At 6-months, VAS scores and WOMAC pain subscores showed that AD-MSCs were the best treatment option (SUCRA=96.7%, SUCRA=85.3%, respectively). According to WOMAC scores and subjective IKDC scores, LP-PRP was the most effective treatment (SUCRA=86.0%, SUCRA=80.5%, respectively). At 12-months, only AD-MSCs were associated with improved VAS scores compared with the placebo (WMD=-20.93, 95%CrI(-41.71, -0.78)). Both LP-PRP and AD-MSCs were more beneficial than the placebo for improving WOMAC pain subscores (WMD=-30.08, 95%CrI(-53.59, -6.25); WMD=-34.85, 95%CrI(-68.03, -4.86), respectively). For WOMAC scores, LP-PRP and LR-PRP were significantly associated with improved WOMAC scores compared with the placebo after sensitivity analysis was performed (WMD=-35.26, 95%Cr(-64.99, -6.01); WMD=-38.69, 95%CrI(-76.21, -2.76)). LP-PRP exhibited relatively better efficacy in improving subjective IKDC scores than the placebo (WMD=13.67, 95%CrI(4.05, 23.39). Regarding safety, all treatments except for LP-PRP (relative risk=1.83, 95%CrI(0.89, 4.64)) increased treatment-related AEs compared with the placebo. CONCLUSIONS Based on the results of current research findings, during 6 months of follow-up, AD-MSCs relieve pain the best; LP-PRP was most effective for functional improvement. During the 12-month follow-up, both AD-MSCs and LP-PRP showed potential clinical pain relief effects; functional improvement was achieved with LP-PRP. Unfortunately, AD-MSC/LP-PRP functional comparisons were only based on WOMAC scores due to missing IKDC scores. BM-MSCs seem to have potentially beneficial effects, but the wide credibility interval make it impossible to draw a well-supported conclusion. HA viscosupplementation clinical efficacy was lower than that of biological agents during follow-up, which may be related to the properties of the drugs. Considering the evaluation of treatment-related AEs, LP-PRP is the most advisable choice; although the AEs of these treatments are not serious, they may affect treatment compliance and satisfaction. LEVEL OF EVIDENCE Level II, meta-analysis of Level I and II studies.

Zhu W, Ling X, Petersen JD, Liu J, Xiao A, Huang J
Neurosurgical review. 2021
Abstract
Neurosurgical clipping and endovascular coiling are both standard therapies to prevent rebleeding after aneurysmal subarachnoid hemorrhage (aSAH). However, controversy still exists about which is the optimal treatment. This meta-analysis aims to assess the effectiveness and safety of two treatments with high-quality evidence. Web of Science, Cochrane Library, EMBASE, Pubmed, Sinomed, China National Knowledge Infrastructure, and Wanfang Data databases were systematically searched on August 5, 2021. Randomized controlled trials (RCTs) and prospective cohort studies that evaluated the effectiveness and safety of clipping versus coiling in aSAH patients at discharge or within 1-year follow-up period were eligible. No restriction was set on the publication date. Meta-analyses were conducted to calculate the pooled estimates and 95% confidence intervals (CI) of relative risk (RR). Eight RCTs and 20 prospective cohort studies were identified. Compared to coiling, clipping was associated with a lower rebleeding rate at discharge (RR: 0.52, 95% CI: 0.29--0.94) and a higher aneurysmal occlusion rate (RR: 1.33, 95% CI: 1.19-1.48) at 1-year follow-up. In contrast, coiling reduced the vasospasm rate at discharge (RR: 1.45, 95% CI: 1.23-1.71) and 1-year poor outcome rate (RR: 1.27, 95% CI: 1.16-1.39). Subgroup analyses presented that among patients with a poor neurological condition at admission, no statistically significant outcome difference existed between the two treatments. The overall prognosis was better among patients who received coiling, but this advantage was not significant among patients with a poor neurological condition at admission. Therefore, the selection of treatment modality for aSAH patients should be considered comprehensively.

Zhao J, Huang H, Liang G, Zeng LF, Yang W, Liu J
BMC Musculoskelet Disord. 2020;21(1):224
Abstract
BACKGROUND Studies have shown that the combined application of hyaluronic acid (HA) and platelet-rich plasma (PRP) can repair degenerated cartilage and delay the progression of knee osteoarthritis (KOA). The purpose of this study was to explore the efficacy and safety of the intra-articular injection of PRP combined with HA compared with the intra-articular injection of PRP or HA alone in the treatment of KOA. METHODS The PubMed, Cochrane Library, EMBASE and China National Knowledge Infrastructure (CNKI) databases were searched from inception to December 2019. Randomized controlled trials and cohort studies of PRP combined with HA for KOA were included. Two orthopaedic surgeons conducted the literature retrieval and extracted the data. Outcome indicators included the Western Ontario and McMaster Universities Arthritis Index (WOMAC), the Lequesne Index, the visual analogue scale (VAS) for pain, and adverse events (AEs). Review Manager 5.3 was used to calculate the relative risk (RR) or standardized mean difference (SMD) of the pooled data. STATA 14.0 was used for quantitative publication bias evaluation. RESULTS Seven studies (5 randomized controlled trials, 2 cohort studies) with a total of 941 patients were included. In the VAS comparison after 6 months of follow-up, PRP combined with HA was more likely to reduce knee pain than PRP alone (SMD: - 0.31; 95% confidence interval (CI): - 0.55 to - 0.06; P = 0.01 < 0.05). PRP combined with HA for KOA achieved better improvements in the WOMAC Function Score (SMD: -0.32; 95% CI: - 0.54 to - 0.10; P < 0.05) and WOMAC Total Score (SMD: -0.42; 95% CI: - 0.67 to - 0.17; P < 0.05) at the 12-month follow-up than did the application of PRP alone. In a comparison of Lequesne Index scores at the 6-month follow-up, PRP combined with HA improved knee pain scores more than PRP alone (SMD: -0.42; 95% CI: - 0.67 to - 0.17; P < 0.05). In terms of AEs, PRP combined with HA was not significantly different from PRP or HA alone (P > 0.05). CONCLUSIONS Compared with intra-articular injection of PRP alone, that of PRP combined with HA can improve the WOMAC Function Scores, WOMAC Total Score, 6-month follow-up VAS ratings, and Lequesne Index scores. However, in terms of the incidence of AEs, PRP combined with HA is not significantly different from PRP or HA alone.

Pharmacol Res. 2020;(155):104747
Abstract
The effect of roxadustat (FG-4592) on individuals with chronic kidney diseases (CKD) patients receiving or not receiving the dialysis was unclear. The aim of this study was to evaluate the efficacy of roxadustat for the treatment of anemia in patients who are dialysis dependent (DD) or dialysis independent (NDD) CKD. We performed a systematic review of randomised controlled trials (RCTs) comparing treatment with roxadustat versus placebo or epoetin alfa up to November 2019. We investigated the efficacy of roxadustat in the levels of hemoglobin and other clinical parameters in renal anemia in patients with NDD and DD-CKD. We estimated weighted-mean difference (WMD) using random effect models. We included six RCTs comprising 1001 patients of whom 70.6 % were treated with roxadustat and 294 controls. The control group for studies of NDD-CKD patients was placebo whereas an active control of epoetin-alfa was used in studies of DD-CKD patients. Median follow-up time was 8 weeks. All trials were industry-sponsored. Overall, roxadustat increased hemoglobin levels by 1.20 g/dl (95 % CI:0.66, 1.75,P < 0.0001,I(2) = 99.3 %). Hemoglobin levels increased by 1.99 g/dl in NDD-CKD patients versus placebo and 0.52 g/dl in DD-CKD patients versus epoetin-alfa. Roxadustat was associated with a decrease the levels of hepcidin by -49.3 ng/dl (-38.5 ng/dl in NDD patients versus placebo and -27.7 ng/dl in DD patients versus epoetin alfa), a decrease in ferritin of -49.7 mumol/l (-52.2 mumol/l in NDD patients versus placebo and -7.3 mumol/l in DD patients versus epoetin alfa), and increase in total iron-binding capacity of 32.2 mumol/l (14.1 mumol/l in NDD patients versus placebo and 13.6 mumol/l in DD patients versus epoetin alfa). The percentage change in the transferrin saturation levels was -2.07 % (-6%, NDD patients versus placebo, and +3.7 % in DD patients versus epoetin alfa) in anemia associated CKD patients. This review found roxadustast increases the levels of hemoglobin, serum transferrin, intestinal iron absorption, and reduces hepcidin in both NDD and DD-CKD patients. Safety data is still emerging.

Abstract
BACKGROUND High incidence of venous thromboembolic complications in COVID-19 patients was noted recently. OBJECTIVE This study aimed to explore the factors associated with prevalence of venous thromboembolism (VTE) in COVID-19 patients. METHODS A literature search was conducted in several online databases. Fixed effects meta-analysis was performed for the factors associated with prevalence of VTE in COVID-19 patients. RESULTS A total of 39 studies were analyzed in this analysis. The incidence of pulmonary embolism and VTE in severe COVID-19 patients were 17% (95% CI, 13-21%) and 42% (95% CI, 25-60%), respectively. VTE were more common among individuals with COVID-19 of advance age. Male COVID-19 patients are more likely to experience VTE. Higher levels of white blood cell (WBC; WMD = 1.34×109/L; 95% CI, 0.84-1.84×109/L), D-dimer (WMD = 4.21 ug/mL; 95% CI, 3.77-4.66 ug/mL), activated partial thromboplastin time (APTT; WMD = 2.03 s; 95% CI, 0.83-3.24 s), fibrinogen (WMD = 0.49 ug/mL; 95% CI, 0.18-0.79 g/L) and C-reactive protein (CRP; WMD = 21.89 mg/L; 95% CI, 11.44-32.34 mg/L) were commonly noted in COVID-19 patients with VTE. Patients with lower level of lymphocyte (WMD = -0.15×109/L; 95% CI, -0.23-0.07×109/L) was at high risk of developing VTE. The incidence of severe condition (OR = 2.66; 95% CI, 1.95-3.62) was more likely to occur among COVID-19 patients who developed VTE. CONCLUSION VTE is a common complication in severe COVID-19 patients and thromboembolic events are also associated with adverse outcomes.

Abstract
BACKGROUND To investigate the effects of dual plasma molecular adsorption system (DPMAS) on the liver function, electrolytes, inflammation, and immunity in patients with chronic severe hepatitis (CSH). METHODS Total of 162 patients with CSH treated in our hospital from March 2016 to December 2018 were enrolled and equally randomly divided into control group (n = 81) and observation group (n = 81). The patients in control group were treated with plasma exchange, while those in observation group were additionally treated with DPMAS based on the treatment in control group. The liver function, electrolytes, inflammation, and immunity were evaluated and compared between the two groups. RESULTS After treatment, the liver function indexes in observation group were significantly favorable compared with those in control group, with the reduction in TBIL, DBIL, ALT, and rise of CHE levels (P < 0.05). The levels of K(+) , Na(+) , Cl(-) , and Ca(2+) in both groups were significantly improved after treatment (P < 0.05), although there were no significant differences between the two groups (P > 0.05). The levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) in both groups declined after treatment compared with those before treatment, and those levels in observation group were higher than that in control group (P < 0.05). After treatment, the levels of cluster of differentiation 3(+) (CD3(+) ), CD4(+) , and CD4(+) /CD8(+) were higher in observation group than those in control group, with decreasing level of CD8(+) (P < 0.05). CONCLUSION Dual plasma molecular adsorption system can effectively improve the liver function, effectively correct the electrolyte disorders, reduce the inflammatory response, and adjust the immunity in patients with CSH.

Abstract
PURPOSE The purpose of this meta-analysis was to compare platelet-rich plasma (PRP) and hyaluronic acid (HA) in patients with knee osteoarthritis (KOA). METHODS Randomized controlled trials (RCTs) comparing the use of PRP and HA in KOA patients were retrieved from each database from the establishment date to April 2018. Outcome measurements were the Western Ontario and McMaster Universities Arthritis Index (WOMAC), visual analog scale (VAS), International Knee Documentation Committee, and Lequesne Index scores and adverse events. The pooled data were evaluated with Review Manager 5.3.5. RESULTS Fifteen RCTs (N = 1,314) were included in our meta-analysis. The present meta-analysis indicated that PRP injections reduced pain more effectively than HA injections in patients with KOA at six and 12 months of follow-up, as evaluated by the WOMAC pain score; the VAS pain score showed a significant difference at 12 months. Moreover, better functional improvement was observed in the PRP group, as demonstrated by the WOMAC function score at three, six, and 12 months. Additionally, PRP injections did not display different adverse event rates compared with HA injections. CONCLUSION In terms of long-term pain relief and functional improvement, PRP injections might be more effective than HA injections as a treatment for KOA. The optimal dosage, the timing interval and frequency of injections, and the ideal treatment for different stages of KOA remain areas of concern for future investigations.
