Abstract
AIMS: This study aimed to evaluate the effects of hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) on iron metabolism and inflammation in dialysis-dependent chronic kidney disease (DD-CKD) patients. METHODS PubMed, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov websites were searched for randomized controlled trials (RCTs) investigating HIF-PHIs versus ESAs for DD-CKD patients. KEY FINDINGS Twenty studies with 14,737 participants were included in the meta-analysis, which demonstrated no significant difference in the effect of transferrin saturation and ferritin between HIF-PHIs and the ESAs group (MD, 0.65; 95%CI, -0.45 to 1.75; very low certainty; SMD, -0.03; 95% CI, -0.13 to 0.07; low certainty). However, HIF-PHIs significantly increased the iron (MD, 2.30; 95% CI, 1.40 to 3.20; low certainty), total iron-binding capacity (SMD, 0.82; 95% CI, 0.66 to 0.98; low certainty), and transferrin (SMD, 0.90; 95%CI, 0.74 to 1.05; moderate certainty) levels when compared with the ESAs group. In contrast, the hepcidin level and dosage of intravenous iron were significantly decreased in the HIF-PHIs group compared with the ESAs group (MD, -15.06, 95%CI, -21.96 to -8.16; low certainty; MD, -18.07; 95% CI, -30.05 to -6.09; low certainty). The maintenance dose requirements of roxadustat were independent of baseline CRP or hsCRP levels with respect to the effect on inflammation. SIGNIFICANCE HIF-PHIs promote iron utilization and reduce the use of intravenous iron therapy. Furthermore, HIF-PHIs, such as roxadustat, maintain the erythropoietic response independent of the inflammatory state. Thus, HIF-PHIs may be an alternative treatment strategy for anemia in DD-CKD patients, where ESA is hyporesponsive due to iron deficiency and inflammation.

Abstract
BACKGROUND Approximately 40% of adults and 30% of children with Myelin-oligodendrocyte glycoprotein antibody-associated disease (MOGAD) experience a relapsing course, but the optimal relapse prevention therapy remains unclear. A meta- analysis was conducted to investigate the efficacy of azathioprine (AZA), mycophenolate mofetil (MMF), rituximab (RTX), maintenance intravenous immunoglobulin (IVIG), and tocilizumab (TCZ) in prevention of attacks in MOGAD. METHODS English and Chinese-language articles published from January 2010 to May 2022 were searched in PubMed, Embase, Web of Science, Cochrane, Wanfang Data, China National Knowledge Infrastructure (CNKI), and China Science and Technology Journal Database (CQVIP). Studies with fewer than three cases were excluded. Meta-analysis of the relapse-free rate, the change of annualized relapse rate (ARR)and Expanded Disability Status Scale (EDSS) scores before and after treatment, and an age subgroup analysis was performed. RESULTS A total of 41 studies were included. Three were prospective cohort studies, one was an ambispective cohort study, and 37 were retrospective cohort studies or case series. Eleven, eighteen, eighteen, eight, and two studies were included in the meta-analysis for relapse-free probability after AZA, MMF, RTX, IVIG, and TCZ therapy, respectively. The proportions of patients without relapse after AZA, MMF, RTX, IVIG, and TCZ were 65% [95% confidence interval (CI):49%-82%]), 73% (95%CI:62%-84%), 66% (95%CI:55%-77%), 79% (95%CI:66%-91%), and 93% (95%CI:54%-100%), respectively. The relapse-free rate did not significantly differ between the children and adults treated with each medication. Six, nine, ten, and three studies were included in the meta-analysis for the change of ARR before and after AZA, MMF, RTX, and IVIG therapy, respectively. ARR was significantly decreased after AZA, MMF, RTX, and IVIG therapy with a mean reduction of 1.58 (95%CI: [-2.29--0.87]), 1.32 (95%CI: [-1.57--1.07]), 1.01 (95%CI: [-1.34--0.67]), and 1.84 (95%CI: [-2.66--1.02]), respectively. The change in ARR did not significantly differ between children and adults. CONCLUSIONS AZA, MMF, RTX, maintenance IVIG, and TCZ all reduce the risk of relapse in both pediatric and adult patients with MOGAD. The literatures included in the meta-analysis were mainly retrospective studies, so large randomized prospective clinical trials are needed to compare the efficacy of different treatments.

Journal of shoulder and elbow surgery. 2022
Abstract
BACKGROUND Platelet-rich plasma (PRP) is reported as an effective treatment for lateral epicondylitis (LE). Theoretically, different types of PRP have different therapeutic effects. However, there is controversy on the effects of different types of PRP in the treatment of LE. PURPOSE To systematically compare the pain relief, functional improvement and successful rates on treatment of two different types of PRP, by reviewing and summarizing the data available in the current literature on LE after PRP injection. METHODS The PubMed, Medline, Embase, Cochrane Library and Web of science were reviewed. A computerized literature search was performed for related studies published from inception to August 2021 by terms of lateral epicondylitis, tennis elbow, tendinopathy, lateral elbow pain, PRP. PRP involved in present study were divided into leukocyte-poor PRP and leukocyte-rich PRP groups according to different preparation methods. Outcomes of interest included characteristics of the subjects, types and preparations of PRP, clinical outcomes, successful rate and safety of treatment of short-term and long-term follow-up. RESULTS A total of 33 studies included 2420 LE patients. There were 19 studies with LP-PRP, 13 studies with LR-PRP and 1 study involved both LP-PRP and LR-PRP. Patients had significant improved clinical outcomes post-treatment compared to pre-treatment in both groups of PRP. The mean of VAS was ranged from 6.1 to 8.0 before the treatment, 1.5 to 4.0 at short-term and 0.6 to 3.3 at the long-term follow-up in LR-PRP group. The mean of VAS was ranged from 4.2 to 8.4 before the treatment, 1.6 to 5.9 at short-term and 0.7 to 2.7 in the long-term follow-up in LP-PRP group. The DASH score of LR-PRP and LP-PRP were ranged from 47.0 to 54.3 and 30.0 to 67.7 separately before the treatment and 20.0 to 22.0 and 5.5 to 19.0 separately at long-term follow-up. LR-PRP and LP-PRP groups reflected successful rate ranged from 70%-100% and 36%-100% respectively. The complication rate lower in LP-PRP group (3.9%) than LR-PRP group (6.4%), with the major complication was temporary pain after PRP treatment (P = 0.029). CONCLUSION PRP treatment demonstrated a significant improvement with pain relief and functional improvement on lateral epicondylitis regardless types of PRP. There was no significant difference between LR-PRP and LP-PRP in pain relief and functional improvement. The major complication was temporary pain after PRP injection and the complication rate in LP-PRP was lower than LR-PRP.

Abstract
BACKGROUND Intraoperative blood salvage autotransfusion(IBSA) has been widely used in a variety of surgeries, but the use of IBSA in hepatocellular carcinoma (HCC) patients undergoing liver transplantation (LT) is controversial. Numerous studies have reported that IBSA used during LT for HCC is not associated with adverse oncologic outcomes. This systematic review and meta-analysis aims to estimate the clinical prognosis of IBSA for patients with H+CC undergoing LT. METHODS MEDLINE, Embase, Web of Science, and Cochrane Library were searched for articles describing IBSA in HCC patients undergoing LT from the date of inception until May 1, 2022, and a meta-analysis was performed. Study heterogeneity was assessed by I(2) test. Publication bias was evaluated by funnel plots, Egger's and Begg's test. RESULTS 12 studies enrolling a total of 2253 cases (1374 IBSA and 879 non-IBSA cases) are included in this meta-analysis. The recurrence rate(RR) at 5-year(OR=0.75; 95%CI, 0.59-0.95; P=0.02) and 7-year(OR=0.65; 95%CI, 0.55-0.97; P=0.03) in the IBSA group is slightly lower than non-IBSA group. There are no significant differences in the 1-year RR(OR=0.77; 95% CI, 0.56-1.06; P=0.10), 3-years RR (OR=0.79; 95% CI, 0.62-1.01; P=0.06),1-year overall survival outcome(OS) (OR=0.90; 95% CI, 0.63-1.28; P=0.57), 3-year OS(OR=1.16; 95% CI, 0.83-1.62; P=0.38), 5-year OS(OR=1.04; 95% CI, 0.76-1.40; P=0.82),1-year disease-free survival rate(DFS) (OR=0.80; 95%CI, 0.49-1.30; P=0.36), 3-year DFS(OR=0.99; 95%CI, 0.64-1.55; P=0.98), and 5-year DFS(OR=0.88; 95%CI, 0.60-1.28; P=0.50). Subgroup analysis shows a difference in the use of leukocyte depletion filters group of 5-year RR(OR=0.73; 95%CI, 0.55-0.96; P=0.03). No significant differences are found in other subgroups. CONCLUSIONS IBSA provides comparable survival outcomes relative to allogeneic blood transfusion and does not increase the tumor recurrence for HCC patients after LT.

Qu S, Hu Z, Zhang Y, Wang P, Li S, Huang S, Dong Y, Xu H, Rong Y, Zhu W, et al
Advances in wound care. 2021
Abstract
SIGNIFICANCE Platelet-rich plasma (PRP) may be a potential drug for treatment of chronic refractory ulcers, which increase the risk of systemic infection and local canceration. However, the efficacy and safety of clinical application of PRP are still controversial. Thus, this study was aimed to assess the efficacy and safety of PRP in patients with chronic ulcers. Recent Advances: For this meta-analysis, Cochrane's Library, MEDLINE, EMBASE, PubMed, and Web of Knowledge databases were searched. Results were pooled using a random-effects model. The primary outcome was the proportion of completely healed chronic ulcers. CRITICAL ISSUES Seventeen randomized controlled trials (RCTs) were included. Compared with the control group, PRP significantly increased the fraction of healed ulcers (pooled RR =1.50; 95% CI 1.20 to 1.87; I2=47.8%). In autologous PRP (APRP) and homologous PRP (HPRP) subgroups, there were statistical differences between the control group vs. treatment subgroup (pooled RR=1.30, 95% CI 1.10 to 1.54, I2=25.7%; pooled RR=3.53, 95% CI 1.94 to 6.43, I2=0.0%, respectively). In terms of percent of chronic ulcers area healed, there was a statistically significant difference between the PRP-treated group vs. the control group (SMD=1.37, 95%CI=0.91 to 1.82, I2=22.1 %). As for PRP safety, there existed a statistically significant difference between the APRP subgroup and the HPRP subgroup, respectively (pooled RR=0.58; 95% CI 0.35 to 0.98; I2=0.0%) and (pooled RR=4.12; 95% CI 1.55 to 10.96; I2=6.8%). FUTURE DIRECTIONS Our findings shows that PRP may be a beneficial treatment of chronic skin ulcers and that APRP may be much safer than HPRP.

The Efficacy and Safety of Epsilon-Aminocaproic Acid for Perioperative Blood Management in Spinal Fusion Surgery: A systematic review and meta-analysis
Li S, Xing F, Cen Y, Zhang Z
World neurosurgery. 2021
Abstract
BACKGROUND Perioperative blood loss is a major concern in spinal fusion surgery, which often requires blood transfusion. A large amount of perioperative blood loss might increase the risks of various perioperative complications. Recently, there has been a series of clinical studies focusing on the perioperative administration of epsilon-aminocaproic acid (EACA) in spinal fusion surgery. The aim of this review was to evaluate the efficacy and safety of EACA in spinal fusion surgery. METHODS We systematically searched electronic databases (MEDLINE, EMBASE, PubMed, and Cochrane Central Register of Controlled Trials) up to April 2021. The perioperative blood loss, blood transfusion and complication data were extracted and analysed by RevMan Manager 5.3. RESULTS Finally, six randomized controlled studies, involving 398 patients undergoing spinal fusion surgery, were enrolled in this systematic review. Compared with the blank control group, the EACA group had significantly lower total perioperative blood loss, postoperative blood loss, postoperative hemoglobin, postoperative blood transfusion units, total blood transfusion units, and postoperative red blood cell transfusion units. Additionally, no significant differences were observed between the EACA group and control group in intraoperative blood loss, intraoperative blood transfusion units, intraoperative crystalloid administered, hospital stays, operative time, perioperative respiratory complications, and wound bleeding. CONCLUSIONS EACA in patients undergoing spinal fusion surgery is effective in perioperative hemostasis without increasing the incidence of postoperative complications. However, the long-term adverse side of EACA in spinal fusion surgery still need more large-scale trials.

Clinical Effectiveness of Platelet-Rich Plasma for Long-Bone Delayed Union and Nonunion: A Systematic Review and Meta-Analysis
Li S, Xing F, Luo R, Liu M
Frontiers in medicine. 2021;8:771252
Abstract
BACKGROUND More recently, there was a series of clinical studies focusing on local administration of platelet-rich plasma (PRP) in long-bone fracture patients suffering from delayed union and nonunion. Therefore, we performed a systematic review to evaluate the effectiveness of PRP injection for treatment of patients with long-bone delayed union and nonunion. METHODS Relevant clinical trials were selected by the main bibliographic databases, including Medline, PubMed, Embase, Web of Science, and the Cochrane library, to evaluate the effectiveness of PRP for long-bone fracture patients diagnosed with delayed union or nonunion by two reviewers independently. The main outcomes included healing rate, healing duration, pain relief, functional outcome, and complications. RESULTS Finally, thirteen studies including four hundred and fifty-nine participants met the selection criteria and were included in this systematic review. These articles included three randomized controlled studies, one prospective study, and nine retrospective studies. 146 out of 155 (94.19%) patients treated with PRP during operation, and 144 out of 183 (78.69%) patients treated with PRP injection alone, exhibited bone consolidation. The healing rate of the PRP group (85.80%) was higher than that of the control group (60.76%). The mean bony union time of patients treated and untreated with PRP, were, respectively, 4.64 and 5.15 months. Four papers reported that PRP was effective in pain relief of patient with delayed union and nonunion. Complications, including small subcutaneous hematoma, subcutaneous swelling, and postoperative infection, were also reported in enrolled studies. CONCLUSIONS PRP is a promising alternative treatment for patients with long-bone delayed union and nonunion. PRP could successfully promote the healing rate and relieve the pain of patients with delayed union and nonunion. However, the long-term adverse side and functional outcome in application of PRP still need further large-scale trials and long-term follow-up.

Li S, Chen B, Hua Z, Shao Y, Yin H, Wang J
Medicine. 2021;100(12):e25087
Abstract
BACKGROUND Topical hemostatic agents are commonly used for reducing perioperative blood loss and transfusion requirement in primary total knee arthroplasty (TKA), although the optimal option has yet to be defined. This study aimed to evaluate the efficacy and safety of topical hemostatic agents and rank the best intervention using the network meta-analysis (NMA) method. METHODS We searched Web of science, PubMed, and Cochrane Library database up to April 2020, for randomized controlled trials (RCTs) on topical hemostatic agents in primary TKA. The quality of included studies was assessed using the Cochrane "risk of bias" tool. Direct and indirect comparisons were performed for the result of network meta-analysis followed by consistency test. RESULTS Thirty seven RCTs with 3792 patients were included in this NMA and the pooled results indicated that tranexamic acid plus diluted epinephrine (TXA+DEP) displayed the highest efficacy in reducing total blood loss, hemoglobin drop and transfusion requirement. None of the included treatments was found to increase risk of thromboembolic events compared to placebo. According to the results of ranking probabilities, TXA+DEP had the highest possibility to be the best topical hemostatic agent with regard to the greatest comparative efficacy and a relatively high safety level. CONCLUSION Current evidence supports that administration of TXA+DEP may be the optimal topical hemostatic agent to decrease blood loss and transfusion requirement in primary TKA. More direct studies that focused on the topical application of TXA+DEP versus other treatments are needed in the future.

Rigorous Assessment of Guidelines on COVID-19-Related Thrombotic or Thromboembolic Disease: Implications for Clinical Practice of Prevention, Diagnosis, and Treatment
Liang J, Wang Z, Xie J, Liang H, Liang J, Jiang M, Li S
Evidence-based complementary and alternative medicine : eCAM. 2021;2021:5513744
Abstract
PURPOSE Severe COVID-19 patients were prone to develop venous thromboembolism. Unfortunately, to date, there is no evidence of any effective medications for thromboembolism in COVID-19. The management of the disease relies on symptomatic and supportive treatments, giving rise to a variety of guidelines. However, the quality of methodology and clinical recommendations remains unknown. MATERIALS AND METHODS We searched Medline, Cochrane Library, Web of Science, websites of international organizations and medical societies, and gray literature databases. Four well-trained appraisers independently evaluated the quality of eligible guidelines and extracted recommendations using well-recognized guideline appraisal tools. Furthermore, recommendations were extracted and reclassified according to a composite grading system. RESULTS The search identified 23 guidelines that offered 108 recommendations. Guidelines scored average on AGREE II criteria, with Scope and Purpose and Clarity of Presentation highest. Only five (22%) guidelines provided high-quality recommendations. The existed clinical recommendations were inconsistent in terms of prophylaxis, diagnosis, and treatment of thromboembolic disease to some extent. CONCLUSION Current guidelines for COVID-19 thromboembolism are generally of low quality, and clinical recommendations on thromboembolism are principally supported by insufficient evidence. There is still an urgent need for more well-designed clinical trials as evidence to prevent adverse events and improve prognosis during COVID-19 treatment.

Effect of acute normovolemic hemodilution on coronary artery bypass grafting: a systematic review and meta-analysis of 22 randomized trials
Li S, Liu Y, Zhu Y
International journal of surgery (London, England). 2020
Abstract
BACKGROUND Efficacy of minimal acute normovolemic hemodilution (ANH) in avoiding homologous blood transfusion during cardiovascular surgery remains controversial. Postoperative bleeding and transfusion remain a source of morbidity and cost after open heart operations. To better understand the role of acute normovolemic hemodilution (ANH) in coronary artery bypass grafting (CABG), we compared ANH with standard intraoperative care in a systematic review including a standard pairwise meta-analysis of randomized controlled trials (RCTs). METHODS We searched the Cochrane Library, PubMed, EMBASE, Web of Science and Chinese National Knowledge Infrastructure (CNKI) up to April 1, 2020. The primary outcome was to assess the incidence of ANH-related number of allogeneic red blood cell units (ARBCu) transfused. Secondary outcomes included the rate of allogeneic blood transfusion and estimated total blood loss. RESULTS A total of 22 RCTs including 1688 patients were identified for the present meta-analysis. Of these studies, 19 were about CABG with on-pump and three with off-pump. Our pooled result indicated that patients received ANH experienced fewer ARBCu transfusions, with a standardized mean difference (SMD) of -0.60 (95%CI -0.96 to -0.24; P = 0.001). The rate of allogeneic blood transfusion in ANH group was significant reduced when compared with controls, with a relative risk (RR) of 0.65 (95%CI 0.52 to 0.82; P = 0.0002). In addition, less postoperative estimated total blood loss was present, with a SMD of -0.53 (95%CI -0.88 to -0.17; P = 0.004). CONCLUSIONS The present meta-analysis indicated that ANH could reduce the number of ARBCu transfused in the CABG surgery setting. In addition, ANH could also reduce the rate of ARBCu transfusion and estimated total blood loss for CABG patients.
