Abstract
BACKGROUND Current evidence suggests that the mortality rate of intermediate-stage hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remains high. We aimed to investigate the safety and efficacy of double plasma molecular adsorption system (DPMAS) with sequential low-volume plasma exchange (LPE) treatment in intermediate-stage HBV-related ACLF. METHODS This prospective study recruited intermediate-stage HBV-related ACLF patients and was registered on ClinicalTrials.gov (NCT04597164). Eligible patients were randomly divided into a trial group and a control group. Patients in both groups received comprehensive medical treatment. Patients in the trial group further received DPMAS with sequential LPE. Data were recorded from baseline to week 12. RESULTS 50 patients with intermediate-stage HBV-related ACLF were included in this study. The incidence of bleeding events and allergic reactions in the trial group was 12% and 4%, respectively, with no other treatment-related adverse events. The levels of TBIL and PT-INR, and MELD scores after each session of DPMAS with sequential LPE were significantly lower than those before treatment (all p<0.05). The 12-week cumulative liver transplantation-free survival rates in the trial and control groups were 52% and 24%, respectively (p=0.041). The 12-week cumulative overall survival rates in the trial and control groups were 64% and 36%, respectively (p=0.048). The Kaplan-Meier survival analysis revealed significant differences in liver transplantation-free survival (p=0.047) and overall survival (p=0.038) between the trial and control groups. COX regression analysis indicated that BUN (p=0.038), DPMAS with sequential LPE (p=0.048) and COSSH-ACLF II score (p<0.001) were significant risk factors for mortality. CONCLUSION DPMAS with sequential LPE treatment is safe and effective for patients with intermediate-stage HBV-related ACLF. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND The optimal therapeutic window to start intravenous immunoglobulin (IVIG) for Kawasaki disease (KD) is highly debatable. We aimed to summarize the existing literature to evaluate the therapeutic window of IVIG treatment and its correlation with clinical outcomes in KD patients. METHODS We searched the databases from inception to August 26, 2022, without language restrictions. The primary outcomes were initial IVIG resistance and coronary artery lesions (CALs) in acute phase. Secondary outcome was CALs during 1-2 months of follow-up. RESULTS 27 studies involving 41,139 patients were included in this study. Very low-quality evidence showed that the earlier IVIG treatment within 4 days had a higher IVIG-resistance rate (RR, 1.80; 95% CI, 1.50-2.15; P < .00001; I(2) = 75%) than the late treatment. Very low-quality evidence showed that IVIG treatment for more than 7 days was associated with a higher risk of CALs in acute phase(RR, 0.57; 95% CI, 0.40-0.80; P = .001; I(2) = 76%). There was a lower risk of CALs during 1-2 months follow-up for those who started IVIG administration within 10 days from the onset. CONCLUSIONS Overall, IVIG treatment within 7 days of illness seems to be the optimal therapeutic window of IVIG. IVIG treatment within 7 days is found to be effective for reducing the risk of coronary artery lesions and cardiac sequelae in KD patients. The early IVIG treatment within 4 days should be vigilant for the IVIG resistance although large multi-center randomized trials with well design are needed.

Frontiers in surgery. 2021;8:621559
Abstract
Background: Platelet-rich plasma (PRP) has been suggested as an emerging treatment for bone defects. However, whether PRP could enhance the therapeutic efficacy of autologous bone grafting for long bone delayed union or non-union remains unknown. A meta-analysis of randomized and non-randomized controlled trials (RCT and NRCT) was performed to summarize current evidence. Methods: Relevant RCTs and NRCTs comparing the influences of autologous bone grafting on healing of long bone delayed union or non-union with and without PRP were obtained by searching PubMed, Embase, Cochrane's Library, China National Knowledge Infrastructure, and WanFang databases from inception to September 10, 2020. A random-effect model was applied to pool the results with the incorporation of the potential heterogeneity. Subgroup analysis according to study design was also performed. Results: Six RCTs and two NRCTs with 420 patients were included. Compared to patients allocated to autologous bone grafting alone, those allocated to combined treatment with PRP and autologous bone grafting were not associated with higher rates of radiographic bone healing [risk ratio (RR): 1.06, 95% confidence interval (CI): 0.99-1.13, P = 0.09; I (2) = 24%] or excellent/good posttreatment limb function (RR: 1.14, 95% CI: 0.95-1.37, P = 0.37; I (2) = 0%) but was associated with a shorter healing time (mean difference: -1.35 months, 95% CI: -1.86 to -0.84, P < 0.001; I (2) = 58%). Subgroup analysis according to study design showed similar results for the above outcomes (P-values for subgroup difference all >0.10). Conclusions: Combined treatment with PRP and autologous bone grafting may be effective to accelerate the healing of long bone delayed union or non-union compared to autologous bone grafting alone.

Clinics (Sao Paulo, Brazil). 2021;76:e2355
Abstract
OBJECTIVES To evaluate the efficacy of autologous platelet-rich plasma (PRP) gel in the treatment of refractory pressure injuries and its effect on wound healing time and quality of life of patients. METHODS A random number table method was used to group 102 patients with refractory pressure injuries into either a control group (CG) (51 cases) receiving negative pressure wound therapy (NPWT) or a study group (SG) (51 cases) receiving NPWT+PRP gel. RESULTS The total efficacy rate in the SG (92.16%) was higher than that in the CG (76.47%) (p<0.05). The SG exhibited lower visual analog scale (VAS) scores and pressure ulcer scale for healing (PUSH) scores, smaller wound sizes and depths, and shorter wound healing times than the CG after 21 days of treatment (p<0.05). After 6 months of treatment, the SG scored higher than the CG on the psychological, physiological, social functions, and daily activity domains on the World Health Organization Quality of Life (WHOQOL-BREF) scale (p<0.05). The incidence of postoperative complications in the SG (13.73%) was not significantly different from that of the CG (7.84%) (p>0.05). CONCLUSION In the treatment of refractory pressure injuries, PRP gel can accelerate wound healing, reduce wound pain, shorten the treatment cycle, regulate tissue inhibitor matrix metalloproteinase-1 (TIMP-1) and matrix metalloproteinase-9 (MMP-9) levels and the expression of specific proteins in granulation tissue, reduce the levels of the inflammatory factors interleukin-1β (IL-1β), IL-8, and tumor necrosis factor-α (TNF-α), and improve the quality of life of patients without increasing complications.

Annals of clinical and translational neurology. 2021;8(10):2059–2069
Abstract
OBJECTIVE To explore the effect of individualized blood pressure (BP)-lowering treatment on the outcomes of elderly patients with severe intracerebral hemorrhage (ICH). METHODS We performed an exploratory analysis of Controlling Hypertension After Severe Cerebrovascular Event (CHASE) trial, which was a multicenter, randomized, controlled clinical trial. Patients with severe ischemic or hemorrhagic stroke (defined as GCS ≤ 12 or NIHSS ≥ 11) were randomized into individualized versus standard BP-lowering treatment in CHASE trial. In this exploratory analysis, patients with severe ICH were included. The primary outcome was the percentage of patients with 90-day functional independence defined as modified Rankin Scale (mRS) ≤2. RESULTS We included 242 patients with severe ICH in the present analysis, consisting of 142 patients aged <65 years and 100 patients aged ≥65 years. There were significant differences between patients aged ≥65 years and <65 years in the proportion of functional independence (47.9% vs. 15.0%, P < 0.001) and good outcome (73.9% vs. 50.0%, P < 0.001) at day 90. In patients aged ≥65 years, the adjusted individualized BP-lowering treatment had an unequivocal effect on the functional independence at day 90 (21.6% vs. 8.2%, odds ratio [OR]: 4.309, 95% confidence interval [CI]: 1.040-17.859, P = 0.044) and improved the neurological deficits at discharge (∆ NIHSS ≥ 4: 64.7% vs. 34.7%, OR: 4.300, 95% CI: 1.599-11.563, P = 0.004). INTERPRETATION Compared with the younger counterparts, the elderly patients (≥65 years) with acute severe ICH might benefit more from individualized BP-lowering treatment.

The Journal of international medical research. 2020;48(10):300060520964661
Abstract
OBJECTIVE The clinical efficacy of platelet-rich plasma (PRP) in the treatment of osteoarthritis remains controversial. In this paper, we evaluated the clinical efficacy of PRP in the treatment of osteoarthritis using meta-analysis, providing evidence for the selection of clinical treatment options. METHODS We performed a computer-based search of PubMed, Embase, and the Cochrane Library databases to retrieve articles using the search terms "platelet-rich plasma", "osteoarthrosis", and "knee joint". Quality evaluation and data extraction were performed. The combined effect was assessed using RevMan 5.3 software. RESULTS Five randomized controlled trials, involving 320 patients, were included in this study. No significant differences were observed in the International Knee Documentation Committee score, visual analog scale (VAS) score, or the absolute value of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between the experimental and control groups. The absolute value of the VAS score and change in the WOMAC score were significantly decreased and patient satisfaction was increased in the experimental group, as compared with the control group. CONCLUSION The findings of this meta-analysis suggest that intra-articular injection of PRP is an effective treatment for osteoarthritis that can reduce post-operative pain, improve locomotor function, and increase patient satisfaction.

Abstract
The COVID-19 pandemic is persistent worldwide. A prior meta-analysis suggested the association of thrombocytopenia (TCP) with more severe COVID-19 illness and high mortality. Considering newly published studies, we updated the previous meta-analysis to confirm and explain the association of TCP with COVID-19 severity and multiple outcomes. Twenty-four studies with 5637 patients with COVID-19 were included in this study. The weighted incidence of TCP in COVID-19 was 12.4% (95% confidence interval [CI], 7.9%-17.7%). Data synthesis showed that the platelet number was lower in patients with either more severe illness or poor outcomes and even lower in nonsurvivors, with weighted mean differences of -24.56 × 109/L, -22.48 × 109/L, and -49.02 × 109/L, respectively. The meta-analysis of binary outcomes (with and without TCP) indicated the association between TCP and 3-fold enhanced risk of a composite outcome of intensive care unit admission, progression to acute respiratory distress syndrome, and mortality (odds ratio [OR], 3.49; 95% CI, 1.57-7.78). Subgroup analysis by endpoint events suggested TCP to be significantly associated with mortality (OR, 7.37; 95% CI, 2.08-26.14). Overall, the present comprehensive meta-analysis indicated that approximately 12% of hospitalized patients with COVID-19 have TCP, which also represents a sign of more severe illness and poor outcomes.

Journal of clinical gastroenterology. 2020
Abstract
INTRODUCTION The aim of this study was to evaluate the effectiveness of nonsurgical secondary prophylaxis interventions for esophageal varices (EV) rebleeding in cirrhotic patients using network meta-analysis. MATERIALS AND METHODS Secondary prophylaxis of EV rebleeding in cirrhosis is searched on PubMed, Embase, and the Cochrane Library databases. The quality of literatures was extracted by 2 independent investigators according to the requirements of Cochrane Handbook for Systematic Reviews of Interventions, Version 5.0.0. Meta-analysis was performed on Review Manager 5.3 software for the incidence of cirrhosis EV rebleeding, rebleeding-related mortality, and overall mortality; and STATA 15.1 software was used for network meta-analysis. RESULTS In all, 57 randomized controlled trials were reviewed. Endoscopic band ligation (EBL)+argon plasma coagulation has not been recommended by guidelines, and it is rarely used; the number of existing studies and the sample size are small. Considering poor stability of the combined results, these studies were excluded; 55 literatures were included. In terms of reducing the incidence of rebleeding, transjugular intrahepatic portosystemic shunt (TIPS) surface under the cumulative ranking curve (SUCRA) (94.3%) was superior to EBL+endoscopic injection sclerotherapy (EIS) (84.4%), EIS+β-blockers (77.9%), EBL (59.8%), EBL+β-blockers+isosorbide-5-mononitrate (52.7%), EBL+β-blockers (51.4%), EIS (34.2%), β-blockers+isosorbide-5-mononitrate (23.7%), β-blockers (20.8%), and placebo (0.8%). In reducing rebleeding-related mortality, TIPS SUCRA (87.2%) was more efficacious than EBL+EIS (83.5%), EIS (47.9%), EBL+β-blockers (47.4%), β-blockers (41.8%), EBL (34.5%), and placebo (7.6%). In reducing overall mortality, TIPS SUCRA (81.1%) was superior to EBL+EIS (68.9%), EIS+β-blockers (59.2%), EBL+β-blockers (55.4%), EIS (48.8%), EBL (48.7%), β-blockers (34.2%), placebo (3.6%). CONCLUSIONS TIPS was more effective in reducing the incidence of cirrhosis EV rebleeding, rebleeding-related mortality, and overall mortality in cirrhosis. Combined with the above results, TIPS is more likely to be recommended as a secondary prophylaxis intervention for EV in cirrhosis.

Pain Res Manag. 2020;2020:7587936
Abstract
Objective: The purpose of this meta-analysis was to determine whether platelet-rich plasma (PRP) was better than hyaluronic acid (HA) for the treatment of knee osteoarthritis (OA) in overweight or obese patients. Design: Two reviewers independently used the keywords combined with free words to search English-based electronic databases according to Cochrane Collaboration guidelines, such as PubMed, Embase, ScienceDirect, and Cochrane library. The pooled data were analyzed using RevMan 5.3. Results: Ten randomized controlled trials (RCTs) with 1096 patients were included. During the first two months of follow-up, there was no significant difference between the two groups. At the 3rd, 6th, and 12th months of follow-up, the pooled analysis showed that PRP was better than HA for the treatment of knee OA in overweight or obese patients. There were significant differences between the two groups at Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score (3 months: MD = -1.35, [95% CI: -2.19 to -0.50], P=0.002, I (2) = 0%; 6 months: MD = -7.62, [95% CI: -13.51 to -1.72], P=0.01, I (2) = 88%; 12 months: MD = -12.11, [95% CI: -20.21 to -4.01], P=0.003, I (2) = 94%). Conclusions: For overweight or obese patients with knee OA, intra-articular injection of PRP in a short time was not necessarily superior to HA, but long-term use was better than HA in pain and functional relief.

Clinical nephrology. 2019
Abstract
BACKGROUND Patients with chronic kidney disease (CKD) undergoing dialysis often require intravenous iron for iron deficiency anemia (IDA). MATERIALS AND METHODS The Ferumoxytol for Anemia of CKD Trial (FACT), a randomized, multicenter, open-label, phase 4 study, compared the long-term safety and efficacy of ferumoxytol with iron sucrose for the treatment of IDA in patients with CKD undergoing hemodialysis. Patients with IDA and CKD undergoing hemodialysis were randomized 2:1 to ferumoxytol 1.02 g (2 x 510 mg) or iron sucrose 1.0 g (10 x 100 mg) for a 5-week treatment period (TP). Over 11 months, patients underwent additional 5-week TPs whenever IDA (hemoglobin < 11.5 g/dL and transferrin saturation < 30%) was detected. The primary efficacy endpoint was mean change in hemoglobin from baseline to week 5 for each TP. Adverse events were recorded during the study. RESULTS Overall, 293 patients received ferumoxytol (n = 196) or iron sucrose (n = 97). Ferumoxytol was noninferior to iron sucrose regarding hemoglobin change from baseline to week 5. The mean change in hemoglobin in the ferumoxytol and iron sucrose groups was 0.5 and 0.4 g/dL, respectively, in TP 1 (least-squares mean difference, 0.13; 95% confidence interval, -0.11 to 0.36) and 0.6 and 0.3 g/dL, respectively, in TP 2 (0.30; 0.06 - 0.55). Treatment-related and serious adverse events were similar in both groups; no new safety signals emerged. CONCLUSION Long-term administration of ferumoxytol has noninferior efficacy and a similar safety profile to iron sucrose when used to treat IDA in patients with CKD undergoing hemodialysis..
