Abstract
PURPOSE The purpose of this study was to explore whether PRP injection can be a viable alternative to CS injection for conservative treatment of rotator cuff disease. METHODS The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, The Cochrane Library, and Web of Science were searched for English-written randomized controlled trials (RCTs) which compared PRP and CS injections for patients with rotator cuff disease from January 1, 1990, to March 20, 2022. Two evaluators independently screened the literature, extracted data, and assessed the level of evidence and methodological quality of the enrolled studies. The meta-analysis was conducted using RevMan 5.3.3 software. RESULTS Thirteen non-surgical RCTs with 725 patients were included. Compared with CS, PRP provided statistically worse short-term (<2 months) changes (Δ) of the American Shoulder and Elbow Surgeons (ASES) assessment, Δ the Simple Shoulder Test (SST), Δ the Disability of Arm, Shoulder and Hand (DASH) questionnaires but better medium-term (2 to 6 months) Δ DASH, long-term (≥ 6 months) Δ Constant-Murley Score (CMS), Δ ASES and Δ SST. No statistical differences regarding pain reduction were found between the two groups. PRP injections led to worse short-term Δ forward flexion, Δ internal rotation but better medium-term Δ forward flexion and Δ external rotation. PRP had significantly lower rates of postinjection failure (requests for a subsequent injection or surgical intervention prior to 12 months) than CS. No outcome reached the minimal clinically important difference (MCID). After sensitivity analyses by excluding studies with substantial clinical and/or methodological heterogeneity, PRP showed better medium-term Δ ASES, Δ VAS, and long-term Δ VAS which reached the MCID. CONCLUSIONS Without the drawbacks of CS injection, PRP injection is not worse than CS injection in pain relief and function recovery at any time point of the follow-up. PRP injection may reduce rates of subsequent injection or surgery, and might provide better improvement in pain and function in the medium- to long-term. PRP injection can be a viable alternative to CS injection for conservative treatment of rotator cuff disease. LEVEL OF EVIDENCE Systematic review of Level I and II studies.

Abstract
BACKGROUND At present, many studies have described acute pulmonary embolism (PE) as a frequent and prognostically relevant complication of coronavirus disease 2019 (COVID-19) infection. Thus we performed the present analysis of 50 studies to evaluate the risk factors and mortality of PE in COVID-19 patients. METHOD Databases including PubMed, Embase, Cochrane Library and Web of Science were searched to October, 2021. Odds ratio (OR), mean difference (MD) or standard MD was used to evaluate the outcomes. The primary outcomes were the difference of mortality between PE and non-PE COVID-19 patients as well as relevant risk factors of PE in COVID-19 patients. All statistical analyses were performed using the standard statistical procedures provided in Review Manager 5.2. RESULT A total of 50 studies including 10053 patients were included in this meta-analysis. Our results indicated that COVID-19 patients with PE experienced significantly higher mortality than non-PE patients (21.9% vs. 10.7%), with a pooled OR of 2.21 (95% CI 1.30 - 3.76; P = .003). In addition, COVID-19 patients with PE also experienced more mechanical ventilation (MV) (OR 2.21; 95% CI 1.30 - 3.75; P = .003) and invasive mechanical ventilation (IMV) (OR 3.58; 95% CI 2.47 - 5.20; P < .0001) respectively. Univariate analysis (UVA) results indicated the Sequential Organ Failure Assessment (SOFA) score, time to deep venous thrombosis (DVT), nonintensive care unit (non-ICU) patients and no anticoagulation as risk factors of PE for COVID-19 patients. In addition, multivariate analysis also found that SOFA score, D-dimer, BMI > 30 kg/m2 and history of PE were risk factors of PE for COVID-19 patients. CONCLUSION The present analysis indicated that PE increased the mortality of COVID-19 patients. Mechanical ventilation, especially invasive mechanical ventilation, is correlated with an increased incidence of PE in patients with COVID-19. The incidence of PE for COVID-19 patients may be multifactorial and further researches focused on risk factors were needed in the future.

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.

Abstract
OBJECTIVE We conducted this updated meta-analysis to evaluate the effects of PRP in patients with knee or hip OA. METHOD PubMed, Embase, and Web of Science were searched to identify randomized controlled trials (RCTs) that compared the efficacy of PRP with other intra-articular injections. The outcomes of interest included Western Ontario and McMaster (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Visual Analog Scale (VAS), Harris Hip Score (HHS), and International Knee Documentation Committee (IKDC). RESULTS Twenty-four RCTs with 21 at knee OA and three at hip OA were included in this meta-analysis. The PRP injections significantly improved the WOMAC score, VAS score, IKDC score, and HHS score as compared with comparators. The WOMAC pain, stiffness, and physical function scores were also significantly better in the PRP group than in the control group. Most of the evaluated parameters that favored PRP were observed in knee OA but not in hip OA, at short-term (at 1, 2, 3, 6, 12 months) but not long-term follow-up (at 18 months), in RCTs with low risk of bias. CONCLUSIONS Intra-articular PRP injection provided better effects than other injections for OA patients, especially in knee OA patients, in terms of pain reduction and function improvement at short-term follow-up.Key Points* This updated meta-analysis, based on great sample size and high-quality studies, evaluates the effects of PRP in patients with knee or hip OA.* Intra-articular PRP injection provided better effects than other injections for OA patients.* Most of the evaluated parameters that favored PRP were observed in knee OA at short term (at 1, 2, 3, 6, 12 months).

Abstract
The purpose of this study was to estimate the effect of platelet-rich fibrin (PRF) on the control of alveolar osteitis (AO), pain, trismus, soft tissue healing, and swelling following mandibular third molar surgery. A comprehensive search of the literature was conducted through PubMed, Embase, Web of Science, and Cochrane Library up to May 2019. Randomized controlled studies conforming to the inclusion criteria were included. The record screening and data extraction were conducted by two authors independently. The risk of bias assessment was performed according to the guidelines recommended by the Cochrane Collaboration. The quantitative analysis was performed using RevMan version 5.3. Nineteen studies were included in the systematic review and 17 studies were eligible for the meta-analysis. The use of PRF significantly reduced the incidence of AO and postoperative pain when compared to the controls (AO: relative risk 0.43, 95% confidence interval (CI) 0.28 to 0.65, Z=3.90, P<0.0001 (I(2)=0%); pain: day 1, standardized mean difference (SMD) -1.12, 95% CI -1.87 to -0.37, Z=2.93, P=0.003 (I(2)=95%); day 3, SMD -0.93, 95% CI -1.48 to -0.38, Z=3.30, P=0.001 (I(2)=92%); day 7, SMD -1.84, 95% CI -2.98 to -0.71, Z=3.19, P=0.001 (I(2)=97%)). Additionally, the result showed a better soft tissue healing when PRF was used (mean difference -0.63, 95% CI -1.08 to -0.18, Z=2.76, P=0.006 (I(2)=90%)). The use of PRF reduced the incidence of AO and postoperative pain following third molar surgery. Furthermore, PRF may also improve the postoperative soft tissue healing.

Abstract
BACKGROUND A reliable scoring tool to detect the risk of intracerebral hemorrhage (ICH) after intravenous thrombolysis for ischemic stroke is warranted. The present study was designed to develop and validate a new nomogram for individualized prediction of the probability of hemorrhagic transformation (HT) in patients treated with intravenous (IV) recombinant tissue plasminogen activator (rt-PA). METHODS We enrolled patients who suffered from acute ischemic stroke (AIS) with IV rt-PA treatment in our emergency green channel between August 2016 and July 2018. The main outcome was defined as any type of intracerebral hemorrhage according to the European Cooperative Acute Stroke Study II (ECASS II). All patients were randomly divided into two cohorts: the primary cohort and the validation cohort. On the basis of multivariate logistic model, the predictive nomogram was generated. The performance of the nomogram was evaluated by Harrell's concordance index (C-index) and calibration plot. RESULTS A total of 194 patients with complete data were enrolled, of whom 131 comprised the primary cohort and 63 comprised the validation cohort, with HT rate 12.2, 9.5% respectively. The score of chronic disease scale (CDS), the global burden of cerebral small vascular disease (CSVD), National Institutes of Health Stroke Scale (NIHSS) score ≥ 13, and onset-to-treatment time (OTT) ≥ 180 were detected important determinants of ICH and included to construct the nomogram. The nomogram derived from the primary cohort for HT had C- Statistics of 0.9562 and the calibration plot revealed generally fit in predicting the risk of HT. Furthermore, we made a comparison between our new nomogram and several other risk-assessed scales for HT with receiver operating characteristic (ROC) curve analysis, and the results showed the nomogram model gave an area under curve of 0.9562 (95%CI, 0.9221-0.9904, P < 0.01) greater than HAT (Hemorrhage After Thrombolysis), SEDAN (blood Sugar, Early infarct and hyper Dense cerebral artery sign on non-contrast computed tomography, Age, and NIHSS) and SPAN-100 (Stroke Prognostication using Age and NIHSS) scores. CONCLUSIONS This proposed nomogram based on the score of CDS, the global burden of CSVD, NIHSS score ≥ 13, and OTT ≥ 180 gives rise to a more accurate and more comprehensive prediction for HT in patients with ischemic stroke receiving IV rt-PA treatment.

Abstract
Objective: The mobilization and collection of sufficient autologous peripheral blood stem cells (APBSCs) are important for the fast and sustained reconstruction of hematopoietic function after autologous transplantation. This study aims to evaluate the mobilization effect and safety of thrombopoietin (TPO) combined with chemotherapy + G-CSF for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma. Methods: A total of 78 patients were included in the present study. After receiving mobilization chemotherapy, all patients were randomly divided into two groups: TPO group (n=40), patients were given subcutaneous injection of rhTPO + G-CSF, and control group (n=38), patients were given subcutaneous injection of G-CSF. The primary endpoint was the total number of obtained CD34+ cells. The secondary endpoints were the mononuclear cell count, the proportion of target and minimum mobilization, the engraftment time of neutrophils and platelets after APBSCT, the number of platelet and red blood cell infusions, the incidence of infectious fever and fever duration, and TPO-related side effects in patients. Results: TPO participation significantly increased the total CD34+ cell count. A higher proportion of patients in the TPO group achieved the minimum and target CD34+ cells, when compared to the control group. TPO-related adverse events were not observed in either of these groups. In addition, there were no significant differences in engraftment time, the number of platelet and red blood cell transfusions, the incidence of infectious fever, and fever duration between these two groups. Conclusion: TPO combined with chemotherapy + G-CSF can safely and effectively enhance the mobilization effect for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma.

Abstract
BACKGROUND AND AIM Acute variceal bleeding (AVB) is life-threatening. We aimed to systematically review the current evidence regarding the efficacy and safety of terlipressin for AVB in liver cirrhosis. METHODS We searched the PubMed, EMBASE, and Cochrane Library databases. The reference list was also hand-searched. Using a random-effect model, we combined the data obtained according to the different time points when the events developed. Odds ratio (OR) and weighted mean difference (WMD) were calculated. Quality of evidence was evaluated by the GRADE methodology. RESULTS Thirty randomized controlled trials with 3344 patients were included. Compared with no vasoactive drug, terlipressin significantly improved the control of bleeding within 48 hours (OR = 2.94, P = .0008) and decreased the in-hospital mortality (OR = 0.31, P = .008). Compared with somatostatin, terlipressin had a significantly higher risk of complications (OR = 2.44, P = .04). Compared with octreotide, terlipressin had a significantly inferior control of bleeding within 24 hours (OR = 0.37, P = .007). Compared with vasopressin, terlipressin had a significantly lower risk of complications (OR = 0.15, P = .02). Compared with terlipressin combined with endoscopic variceal ligation, terlipressin alone had significantly higher 5-day treatment failure (OR = 14.46, P = .01) and transfusion requirements within 49 to 120 hours (WMD = 1.20, P = .002). No outcome was significantly different between terlipressin and sclerotherapy. Compared with balloon tamponade, terlipressin significantly decreased the 30-day rebleeding (OR = 0.05, P = .001) and transfusion requirements (WMD = -2.70, P = .02). Quality of evidence was very low to moderate. CONCLUSION Our findings were in accordance with the current recommendations regarding terlipressin for the treatment of AVB in cirrhosis. However, due to low quality of evidence, further studies are recommended.

Abstract
BACKGROUND Hip osteoarthritis is one of the most prevalent musculoskeletal degenerative diseases in elderly. Total hip arthroplasty (THA) is the most effective surgical treatment for end stage hip osteoarthritis. Tranexamic acid (TA) is a potent drug to reduce surgical blood loss in surgery, therefore, as a potential drug for application in THA. OBJECTIVES To identify the combined efficacy of TA administration in THA. A meta-analysis including 25 randomized controlled trials was conducted for generating synthesized effects. METHODS This meta-analysis followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines for reporting systematic reviews and meta-analysis. A total of 25 Randomized controlled trials (RCTs) were included for meta-analysis. RESULTS The pooled results illustrated that total blood loss, intraoperative blood loss, postoperative blood loss, hemoglobin drop, transfusion rate, and average hospital stay were significantly lower than controls (standardized mean difference or odds ratio (OR) (95%CI): -0.87, (-1.13,-0.61), -0.68, (-0.96,-0.39), -1.41, (-2.24,-0.59), -1.11, (-1.63,-0.58), 0.28, (0.20,-0.38), -0.17, (-0.49,0.14), P < .05, respectively). Moreover, TA acts efficiently without increasing risk of thromboembolic events with OR = 1.14, 95%CI = 0.50-2.62, P = .75. Subgroup analysis indicated no statistically significant differences between a higher dose of topical TA (≥2 g or 15 mg/kg) or a lower dose (<2 g or 15 mg/kg). CONCLUSION The findings indicated that TA is clinically effective and safe in patients receiving total hip arthroplasty.

International Journal of Surgery (London, England). 2016;38:109-116
Abstract
OBJECTIVE Platelet-rich plasma (PRP) is extracted by centrifuging whole blood and characterized with a high concentration of platelets. The purpose of this systematic review and meta-analysis of randomized controlled trials (RCTs) and non-RCTs is to evaluate the efficacy and safety of platelet-rich plasma (PRP) versus placebo after total knee arthroplasty (TKA). METHODS The Electronic databases of PubMed, Web of Science, Embase and Cochrane Database of Systematic Reviews were searched from inception to November, 2016 and any studies involving PRP versus placebo for patients prepared for TKA were selected by two reviewers. The primary endpoint is the range of motion (ROM), which represents the function after TKA. The Western Ontario McMaster Universities Osteoarthritis Index Bellamy (WOMAC), pain at 24 h, 48 h and 7 day are also assessed the effect of PRP on the function and pain after TKA. The complications of infection is also compiled to assess the safety of PRP. Stata 12.0 was used to synthesis the final results. RESULTS Eleven clinical trials with 1316 patients are included in the meta-analysis. The pooled results indicate that administration PRP significantly increase ROM on the third day (MD=4.72, 95 % CI 2.74, 6.69; P=0.000) and 3 month postoperatively (MD=7.55, 95 % CI 5.91, 9.19; P=0.000). There is no statistical difference between the two groups in terms of WOMAC questionnaire score in 3 months (MD=-4.88, 95 % CI -12.12, 2.41; P=0.190). There were no statistical significance between the two groups in pain intensity at 24 h, 48 h and 7 day. There is no statistically significant difference between the PRP versus placebo in terms of the occurrence of infection (RR=0.64, 95%CI: 0.19 approximately 2.14, P=0.464). CONCLUSION Current meta-analysis indicates that PRP is associated with increasing the ROM after TKA in short term and long term. What's more, PRP can also decrease the WOMAC score and pain intensity without increasing the occurrence of infection.
