OBJECTIVES To evaluate patient-reported outcomes and radiographic results of simultaneous implant placement in severely atrophic maxilla using flapless endoscope-assisted osteotome sinus floor elevation with platelet-rich fibrin (PRF), also defined as PESS, and to compare the results with those of lateral sinus floor elevation (LSFE). METHODS Patients with a residual bone height (RBH) of 2-6 mm were included in a randomised controlled trial. PESS was performed with PRF as the sole grafting material. LSFE was performed using deproteinised bovine bone matrix. Patient-reported outcomes were recorded on a visual analogue scale (VAS-pain) and visual rating scale (VRS-swelling and VRS-willingness). Peri-implant bone height (PBH), bone mineral density (BMD), and sinus grafting remodelling index were measured using CBCT immediately postoperatively and 3(rd) , 6(th) and 18(th) months post-surgery. RESULTS The study population consisted of 20 patients in each group. The RBH of two groups averaged 3.35±0.79 mm and 2.92±0.63 mm with no significant difference (p > 0.05). VAS-pain was 18.0 (IR 15.0-22.5) and 35.0 (IR 32.5-37.0) in the PESS and LSFE groups, respectively (p < 0.01). VAS-pain decreased with time in both groups. VRS-swelling was lower in the PESS group than LSFE group. VRS-willingness was higher in the PESS group than LSFE group (p < 0.01). At 18 months post-surgery, the marginal bone loss was 0.60±0.25 mm and 0.69±0.35 mm in the two groups with no significant difference (p = 0.52). CONCLUSIONS Within the limitations of this study, PESS was associated with lower postoperative morbidity and was more tolerable than LSFE. PESS could be a reliable procedure for sinus floor elevation in patients with insufficient RBH.

This meta-analysis evaluated the efficacy and safety of infliximab as initial therapy for patients with Kawasaki disease (KD) and intravenous immunoglobulin (IVIG) resistant KD.Studies of infliximab in KD, published between January 2004 and December 2019, were curated from PubMed, MEDLINE, and Cochrane Library. Data were analyzed using STATA Version 12.0. Of the 8 studies considered, 4 evaluated the effect of infliximab combined with IVIG as primary therapy in KD, and the remaining investigated the effect of infliximab in IVIG resistant patients. Infliximab was more effective than the control group, with the total summary odds ratio (OR) of 0.34 (95% confidence interval (CI): 0.19-0.62). The treatment resistance of the infliximab group was lower than the IVIG group (0.36 [95% CI: 0.14-0.92]) when infliximab was combined with IVIG as the initial treatment. However, infliximab treatment for IVIG resistant KD was more effective than the IVIG group (0.28 [95% CI: 0.12-0.66]). There was no significant increase in the incidence of coronary artery lesions. The total summary OR for the incidence of coronary artery lesions and infliximab treatment was 0.88 (95% CI: 0.48-1.62). There was no statistically significant difference in adverse events (AEs) when compared between the groups (0.71 [95% CI: 0.44-1.16]).Infliximab combined with IVIG reduced treatment resistance in KD patients vs. conventional IVIG therapy. Infliximab improved clinical course in IVIG resistant KD patients. Infliximab treatment did not reduce the incidence of coronary artery lesions and did not show any significant increase in the incidence of AEs. PROSPERO REGISTRATION NUMBER CRD42020218554.

The present study aimed to review the relevant studies in order to determine the efficacy of infliximab (IFX) in the treatment of Kawasaki disease (KD). The relevant studies were retrieved using the PubMed, Cochrane and Embase databases. Key sources in the literature were reviewed; all articles published by July 2019 were considered for inclusion. For each study, odds ratios, mean difference and 95% confidence interval (95% CI) were assessed to evaluate study outcomes. A total of 16 studies involving 429 patients were relevant to the questions of interest of the current meta-analysis. Compared with intravenous immunoglobulin (IVIG), IFX or IFX plus IVIG significantly reduced the incidence of adverse events, including the number of patients with fever, changes in lip and oral cavity and/or cervical lymphadenopathy. The white blood cell (WBC), neutrophil and C-reactive protein (CRP) levels were also reduced in the IFX or IFX plus IVIG group compared with those in the IVIG or polyethylene glycol-treated human immunoglobulin (VGIH) groups. The platelet counts, alanine aminotransferase (ALT) levels and Z-scores were increased in the IFX or IFX plus IVIG groups compared with those in the IVIG or VGIH groups. In the single-arm studies, the incidence of coronary artery aneurysm was 0.150 (95% CI: 0.024, 0.277), the non-response rate was 0.097 (95% CI: 0.056, 0.138), and the incidence of adverse events was 0.156 (95% CI: 0.122, 0.190). IFX not only effectively reduced the incidence of fever, conjunctival injection, changes in lip and oral cavity and cervical lymphadenopathy polymorphous exanthema, but also the WBC, neutrophil, ALT and CRP levels. The platelet levels were increased in patients after the IFX therapy compared with patients in the IVIG or VGIH groups. IFX or IFX plus IVIG exhibited improved clinical efficacy in the treatment of KD compared with that of IVIG or VGIH. However, as a limited number of studies was included in the current study, the findings should be verified further.

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.

BACKGROUND Major bleeding and allogeneic transfusion leads to negative outcomes in patients receiving cardiac surgery with cardiopulmonary bypass (CPB). Ulinastatin, a urine trypsin inhibitor, relieves systemic inflammation and improves coagulation profiles with however sparse evidence of its effects on blood loss and allogeneic transfusion in this specific population. METHODS In this prospective randomized controlled trial, 426 consecutive patients receiving open heart surgery with CPB were randomly assigned into three groups to receive ulinastatin (group U, n = 142), tranexamic acid (group T, n = 143) or normal saline (group C, n = 141). The primary outcome was the total volume of post-operative bleeding and the secondary outcome included the volume and exposure of allogeneic transfusion, the incidence of stroke, post-operative myocardial infarction, renal failure, respiratory failure and all-cause mortality. A ten-year follow-up was carried on to evaluate long-term safety. RESULTS Compared with placebo, ulinastatin significantly reduced the volume of post-operative blood loss within 24 h (688.39 +/- 393.55 ml vs 854.33 +/- 434.03 ml MD - 165.95 ml, 95%CI - 262.88 ml to - 69.01 ml, p < 0.001) and the volume of allogeneic erythrocyte transfusion (2.57 +/- 3.15 unit vs 3.73 +/- 4.21 unit, MD-1.16 unit, 95%CI - 2.06 units to - 0.26 units, p = 0.002). The bleeding and transfusion outcomes were comparable between the ulinastatin group and the tranexamic acid group. In-hospital outcomes and 10-year follow-up showed no statistical difference in mortality and major morbidity among groups. CONCLUSIONS Ulinastatin reduced post-operative blood loss and allogeneic erythrocyte transfusion in heart surgery with CPB. The mortality and major morbidity was comparable among the groups shown by the 10-year follow-up. TRIAL REGISTRATION The trial was retrospectively registered on February 2, 2010.

BACKGROUND Sepsis is characterized by a complex immune response. This meta-analysis evaluated the clinical effectiveness of intravenous IgM-enriched immunoglobulin (IVIgGM) in patients with sepsis and septic shock. METHODS Four databases, PubMed, the Cochrane Library, the ISI Web of Knowledge, and Embase, were systematically searched from inception to June 2018 to update the 2013 edition of the Cochrane review by two investigators, who independently selected studies, extracted relevant data, and evaluated study quality. Data were subjected to a meta-analysis and trial sequential analysis (TSA) for the primary and secondary outcomes. Level of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scale. RESULTS Nineteen studies comprising 1530 patients were included in this meta-analysis. Pooled analyses showed that the use of IVIgGM reduced the mortality risk of septic patients (relative risk 0.60; 95% confidence interval [CI] 0.52-0.69, I(2) = 0%). TSA showed that IVIgGM had a significant effect on mortality. Additionally, the meta-analysis suggested that use of IVIgGM shortened length of mechanical ventilation (mean difference - 3.16 days; 95% CI - 5.71 to - 0.61 days) and did not shorten length of stay in the intensive care unit (mean difference - 0.38 days; 95% CI - 3.55 to 2.80 days). The GRADE scale showed that the certainty of the body of evidence was low for both benefits and IVIgGM. CONCLUSION Administration of IVIgGM to adult septic patients may be associated with reduced mortality. Treatment effects tended to be smaller or less consistent when including only those studies deemed adequate for each indicator. The available evidence is not clearly sufficient to support the widespread use of IVIgGM in the treatment of sepsis. Trial registration PROSPERO registration number: CRD42018084120.

BACKGROUND The efficacy of tranexamic acid (TXA) to reduce perioperative blood loss and allogeneic blood transfusion in cardiac surgeries has been proved in previous studies, but its adverse effects especially seizure has always been a problem of concern. This meta-analysis aims to provide information on the optimal dosage and delivery method which is effective with the least adverse outcomes. METHODS We searched Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE for all relevant articles published before 2018/12/31. Inclusion criteria were adult patients undergoing elective heart surgeries, and only randomized control trials comparing TXA with placebo were considered. Two authors independently assessed trial quality and extracted relevant data. RESULTS We included 49 studies with 10,591 patients into analysis. TXA significantly reduced transfusion rate (RR 0.71, 95% CI 0.65 to 0.78, P<0.00001). The overall transfusion rate was 35%(1573/4477) for patients using TXA and 49%(2190/4408) for patients in the control group. Peri-operative blood loss (MD - 246.98 ml, 95% CI - 287.89 to - 206.06 ml, P<0.00001) and re-operation rate (RR 0.62, 95% CI 0.49 to 0.79, P<0.0001) were also reduced significantly. TXA usage did not increase risk of mortality, myocardial infarction, stroke, pulmonary embolism and renal dysfunction, but was associated with a significantly increase in seizure attack (RR 3.21, 95% CI 1.04 to 9.90, P = 0.04).The overall rate of seizure attack was 0.62%(21/3378) for patients using TXA and 0.15%(5/3406) for patients in the control group. In subgroup analysis, TXA was effective for both on-pump and off-pump surgeries. Topical application didn't reduce the need for transfusion requirement, while intravenous delivery no matter as bolus injection alone or bolus plus continuous infusion were effective. Intravenous high-dose TXA didn't further decrease transfusion rate compared with low-dose regimen, and increased the risk of seizure by 4.83 times. No patients in the low-dose group had seizure attack. CONCLUSIONS TXA was effective in reducing transfusion requirement in all kinds of cardiac surgeries. Low-dose intravenous infusion was the most preferable delivery method which was as effective as high-dose regimen in reducing transfusion rate without increasing the risk of seizure.

AIMS: Safety evaluations of tranexamic acid (TXA) remain sparse, especially with respect to its impact on long-term outcomes in patients undergoing on-pump coronary artery bypass grafting (CABG). We hypothesized that the effects of TXA on perioperative bleeding and allogeneic transfusion and its impact on long-term clinical outcomes of patients receiving on-pump CABG are superior to those in the control group. METHODS In this prospective, randomized, placebo-controlled trial, 210 patients undergoing primary and isolated on-pump CABG were randomly assigned to receive TXA or a corresponding volume of saline solution. Randomly assigned patients were followed up at 1, 3, 5, and 7 years after hospital discharge. Finally, 163 patients fulfilled the 7-year follow-up. The primary outcome was allogeneic red blood cell (RBC) transfusion. Long-term mortality and morbidity were also evaluated. RESULTS Compared with placebo, TXA reduced the allogeneic RBC requirement in terms of the volume transfused (4.20+/-4.06 vs. 6.25+/-4.86 units; p<0.01), ratio exposed (52.0% vs. 71.6%; p<0.01), and blood loss volume (879.0+/-392.5 vs. 1154.0+/-582.8 mL; p<0.01). Except for myocardial infarction, there were no significant differences in mortality or morbidity between the two groups during the 7-year follow-up. The TXA group had a lower rate of myocardial infarction than did the placebo group (0.0% vs. 4.9% at 84 months; p=0.03). CONCLUSIONS TXA significantly decreased postoperative bleeding and allogeneic transfusion in patients undergoing on-pump CABG. The 7-year follow-up suggested that the use of TXA was safe and might play a potential role in the prevention of long-term myocardial infarction. This article is protected by copyright.

The purpose of this study was to identify the clinical features and laboratory factors that are predictive of intravenous immunoglobulin (IVIG)-resistant Kawasaki disease. Multiple databases were searched for relevant studies on IVIG-resistant Kawasaki disease published from January 2002 to April 2017. Eligible studies were retrieved by manual review of the references. Stata 12 was used for the meta-analysis. Weighted mean differences and odds ratios with 95% confidence intervals were calculated for several indices. Twenty-eight studies involving 26,260 patients comprising 4442 IVIG-resistant Kawasaki disease patients and 21,818 IVIG-sensitive Kawasaki disease patients were included. The meta-analysis showed that the erythrocyte sedimentation rate (ESR) in the IVIG-resistant group was significantly higher than that in the IVIG-sensitive group, and that platelet count and hemoglobin levels were significantly lower in the IVIG-resistant group. The patients with oral mucosa alterations, cervical lymphadenopathy, swelling of the extremities, polymorphous rash, and initial administration of IVIG ≤ 4.0 days after the onset of symptoms were more likely to be IVIG resistant. CONCLUSION The initial administration of IVIG ≤ 4.0 days after the onset of symptoms increased ESR and decreased hemoglobin and platelet counts, oral mucosa alterations, cervical lymphadenopathy, swelling of the extremities, and polymorphous rash and are the risk factors for IVIG-resistant Kawasaki disease. What is Known: * Recent reports on this topic are about aspartate aminotransferase (AST), alanine aminotransferase (ALT), gammaglutamyl transferase, total bilirubin, white blood cells, platelets, erythrocyte sedimentation rate (ESR), polymorphonuclear leukocytes (PMN), C-reactive protein (CRP), pro-brain natriuretic peptide (BNP), albumin, and sodium as the risk factors in the IVIG-resistant Kawasaki disease; however, no studies have been published on clinical features as predictors of IVIG resistance. What is New: * This meta-analysis identified the clinical features, the initial administration of IVIG ≤ 4.0 days after the onset of symptoms, and much more comprehensive laboratory indicators, such as hemoglobin, as predictors of IVIG-resistant Kawasaki disease.

Therapeutics and Clinical Risk Management. 2018;14:1191-1204.
Purpose: The debate is still ongoing on the effectiveness and safety of erythropoietin (EPO) treatment in orthopedic surgeries. Specifically, previous studies have not compared the dynamic change of hemoglobin (Hb) levels between different transfusion methods. Besides, complications or side effects of this alternative have not been quantitatively analyzed. We conducted a meta-analysis and systemic review to evaluate the efficacy of EPO on Hb levels observed during the whole perioperative period as well as the volume of allogeneic blood transfusion (ABT), the risk of venous thromboembolism, and application frequency of ABT in hip and knee surgery. Materials and methods: PubMed, Embase, Web of Science, and the Cochrane library were systematically searched from inception to November 2017. The data from randomized controlled trials were extracted and the risk of bias assessed using Cochrane's Collaboration's tool. Results: Twenty-five randomized controlled trials involving 4,159 patients were included in this meta-analysis. EPO could reduce exposure to allogeneic blood transfused (odds ratio [OR] =0.42, P=0.001) and reduce the average volume of allogeneic blood transfused (OR = -0.28, P=0.002). When EPO and preoperative autologous blood donation (PABD) were compared, the use of EPO was associated with lower exposure to ABT (OR =0.48, P=0.03), but no significant decrease in the average volume of allogeneic blood transfused (OR = -0.23, P=0.32). The use of EPO was associated with a higher level of Hb with or without use of PABD at all the 4 time points (preoperation, 24-48 hours postoperation, 3-5 days postoperation, discharge of last observation) (P<0.0001), which means EPO could increase the level of Hb significantly during the perioperative period. The results also indicated EPO does not increase the risk of a venous thromboembolism event. Conclusion: Preoperative administration of EPO was shown to generally increase Hb levels during the whole perioperative period; however, the extent of the positive effects varies with time points. Additionally, EPO minimizes the need for transfusion significantly in patients undergoing hip or knee surgery without increasing the chance of developing thrombotic complications. Therefore, EPO offers an alternative blood management strategy in total hip arthroplasty and total knee arthroplasty.
