Abstract
OBJECTIVES To evaluate the effect of platelet-rich fibrin alone or in combination with different biomaterials for the treatment of periodontal intra-bony defect. METHODS Up to April 2022, Cochrane library, Medline, EMBASE, and Web of Science databases were searched for randomized clinical trials. The outcomes of interest were probing pocket depth reduction, clinical attachment level gain, bone gain, and bone defect depth reduction. Bayesian network meta-analysis with 95% credible intervals was calculated. RESULTS Thirty-eight studies with 1,157 participants were included. Platelet-rich fibrin alone or platelet-rich fibrin +biomaterials showed a statistically significant difference when compared with open flap debridement (P<0.05, low to high certainty evidence). Neither biomaterials alone nor platelet-rich fibrin +biomaterials showed a statistically insignificant difference when compared to platelet-rich fibrin alone (P>0.05, very low to high certainty evidence). Platelet-rich fibrin +biomaterials showed insignificant differences as compared to biomaterials alone (P>0.05, very low to high certainty evidence). Allograft +collagen membrane ranked the best in probing pocket depth reduction while platelet-rich fibrin +hydroxyapatite ranked the best in bone gain. CONCLUSION It seems that 1) Platelet-rich fibrin with/without biomaterials were more effective than open flap debridement. 2) Platelet-rich fibrin alone provides a comparable effect to biomaterials alone and platelet-rich fibrin +biomaterials. 3)Platelet-rich fibrin +biomaterials provide a comparable effect to biomaterials alone. Although allograft +collagen membrane and platelet-rich fibrin +hydroxyapatite ranked the best in terms of probing pocket depth reduction and bone gain respectively, the difference between different regenerative therapies remains insignificant, and therefore, further studies are still needed to confirm these results.

PloS one. 2023;18(3):e0282726
Abstract
BACKGROUND Although some studies have shown that tranexamic acid is beneficial to patients with intracranial haemorrhage, the efficacy and safety of tranexamic acid for intracranial haemorrhage remain controversial. METHOD The PubMed, EMBASE, and Cochrane Library databases were systematically searched. The review followed PRISMA guidelines. Data were analyzed using the random-effects model. RESULTS Twenty-five randomized controlled trials were included. Tranexamic acid significantly inhibited hematoma growth in intracranial hemorrhage (ICH) and traumatic brain injury (TBI) patients. (ICH: mean difference -1.76, 95%CI -2.78 to -0.79, I2 = 0%, P < .001; TBI: MD -4.82, 95%CI -8.06 to -1.58, I2 = 0%, P = .004). For subarachnoid hemorrhage (SAH) patients, it significantly decreased the risk of hydrocephalus (OR 1.23, 95%CI 1.01 to 1.50, I2 = 0%, P = .04) and rebleeding (OR, 0.52, 95%CI 0.35 to 0.79, I2 = 56% P = .002). There was no significance in modified Rankin Scale, Glasgow Outcome Scale 3-5, mortality, deep vein thrombosis, pulmonary embolism, or ischemic stroke/transient ischemic. CONCLUSION Tranexamic acid can significantly reduce the risk of intracranial haemorrhage growth in patients with ICH and TBI. Tranexamic acid can reduce the incidence of complications (hydrocephalus, rebleeding) in patients with SAH, which can indirectly improve the quality of life of patients with intracranial haemorrhage.

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.

Abstract
BACKGROUND In the era of bare stents, transjugular intrahepatic portosystemic shunt (TIPS) is the second-line choice of therapy for the prevention of variceal rebleeding in liver cirrhosis. In the era of covered stents, the role of TIPS should be re-evaluated. AIM: The aim of the study was to compare the outcomes of covered TIPS versus the traditional first-line therapy (i.e, drug plus endoscopic therapy) for the prevention of variceal rebleeding in liver cirrhosis. METHODS All relevant randomized controlled trials were searched via the PubMed, EMBASE, and Cochrane Library databases. Hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) and P values were calculated for the cumulative risk and overall risk, respectively. Heterogeneity among studies was also calculated. RESULTS Three of 111 retrieved papers were eligible. Among them, the proportion of patients who were switched from drug plus endoscopic therapy to TIPS was 16% to 25%. The risk of bias was relatively low in all included randomized controlled trials. Meta-analyses demonstrated that the covered TIPS group had a similar overall survival (HR = 0.84, 95% CI = 0.55-1.28, P = 0.41; OR = 1.00, 95% CI = 0.59-1.69, P = 0.99), a significantly lower risk of variceal rebleeding (HR = 0.30, 95% CI = 0.18-0.48, P < 0.00001; OR = 0.24, 95% CI = 0.12-0.46, P < 0.0001), and a similar risk of hepatic encephalopathy (HR = 1.35, 95% CI = 0.72-2.53, P = 0.36; OR = 1.28, 95% CI = 0.54-3.04, P = 0.57). In most of meta-analyses, the heterogeneity among studies was not statistically significant. CONCLUSIONS Compared with drug plus endoscopic therapy, covered TIPS had a significant benefit of preventing from variceal rebleeding, but did not increase the overall survival or risk of hepatic encephalopathy.
