Abstract

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.

Abstract

BACKGROUND Postpartum hemorrhage (PPH) is a major obstetric complication, and the real-time measurement of blood loss is important in the management and treatment of PPH. We designed a new two-set liquid collection bag (TSLCB) for measuring postpartum blood loss in vaginal delivery. The aim of this study was to evaluate the effectiveness of the TSLCB in separating the blood from the amniotic fluid during vaginal delivery and in determining the accuracy of the measured postpartum blood loss. METHODS A prospective, randomized, case control study was conducted in the Women's Hospital, Zhejiang University School of Medicine, from March 2018 to April 2018. Sixty single pregnant women with spontaneous labor at 37-41 weeks without maternal complications were randomly divided into the experimental and control groups. The TSLCB was used to evaluate separately the amount of blood and amniotic fluid. For the control group, visual estimation and traditional plastic blood-collecting consumables were used to estimate the amount of postpartum blood loss. The measured blood loss between the two groups was compared, and the association of the measured blood loss with various clinical lab indices and vital signs was investigated. RESULTS The TSLCB (the experimental group) improved the detection of the measured blood loss compared with visual estimation and the traditional method (the control group) (P < .05). In the experimental group, correlation analysis showed that the measured blood loss at delivery and within 24 h of delivery was significantly associated with the decreased hemoglobin level, red blood cell count, and hematocrit level of patients (r = -0.574, -0.455, -0.437; r = 0.-595, -0.368, -0.374; P < .05). In the control group, only the measured blood loss within 24 h of delivery was associated with the decreased hemoglobin level (r = -0.395, P < .05). No blood transfusion and plasma expanders were required in the treatment of PPH for both groups. CONCLUSIONS The TSLCB can be used to accurately measure the postpartum blood loss in vaginal delivery by medical personnel.

Abstract

PURPOSE Oxidized cellulose is available in many forms, but manufactured using either a regenerated or non-regenerated process. In this study, we evaluated the effects of 2 different hemostatic agents for the treatment of local bleeding in patients undergoing hepatic resection. METHODS This was a monocentric, parallel-group, randomized, and controlled clinical trial to compare oxidized regenerated cellulose gauze (ORCG) with oxidized non-regenerated cellulose gauze (ONRCG) in patients undergoing hepatectomy. The primary endpoint was the time to hemostasis at the target bleeding site. The secondary endpoints were the postoperative drainage volume on the first 2 days after surgery and the hospital stay. RESULTS There was no significant difference between the ORCG and ONRCG groups in time to hemostasis from column analysis (238.8 ± 121.6 seconds vs. 193.7 ± 85.3 seconds, P = 0.068), and there were no differences in the rates of hemostatic success between the 2 groups at 120 seconds (18.4% vs. 24.3%; odds ratio [OR], 0.703; 95% confidence interval [CI], 0.231-2.136) and 300 seconds (71.1% vs. 89.2%; OR, 0.298; 95% CI, 0.085-1.041). However, the ONRCG group was superior to the ORCG group in hemostasis according to the survival analysis (log-rank test, P = 0.044). Moreover, there were also no significant differences between the 2 groups in postoperative drainage volume on the first 2 days (P = 0.436, P = 0.381) and hospital stay (P = 0.537, P = 0.200). CONCLUSION ONRCG was not inferior to ORCG as a hemostatic agent in patients undergoing liver resection.

Abstract

BACKGROUND We aimed to assess the efficacy of different initial intravenous immunoglobulin (IVIG) regimens in Kawasaki disease (KD) patients to find more cost-effective therapy options. METHODS A multicentre, open-label, blind-endpoint randomized controlled trial was conducted from January 2014 to December 2015. KD Patients within 10 days of illness were randomly assigned to receive different IVIG regimens (Group A, 2 g/kg once; Group B, 1 g/kg for 2 consecutive days; Group C, 1 g/kg once) and aspirin 30mg/kg/d. Primary outcomes included hours to defervescence and development of coronary artery lesions (CAL) during the study period. Major secondary outcomes included total fever days, total dose of IVIG, changes of laboratory data, length of stay, and hospitalization expenses. (ClinicalTrials.gov: NCT02439996). RESULTS A total of 404 patients underwent randomization. No difference was found in the outcomes of defervescence among three groups at 6, 12, 24, and 36 hours after completion of initial IVIG infusion. There were no differences in the incidence of CAL during the study period (at week 2, month 1, month 3, and month 6 of illness), changes of laboratory data, total fever days and length of stay. Group C patients had the lowest total dose of IVIG (mean: 1.2 vs 2.2 vs 2.1 g/kg; P<0.001) and hospitalization expenses (mean: 8443.8 vs 10798.4 vs 11011.4 RMB; P<0.001) than other two groups. CONCLUSIONS A single dose of 1g/kg IVIG is a low-cost treatment with the same efficacy as 2 g/kg IVIG and can be an option for the initial therapy of KD patients.

Abstract

BACKGROUND Recurrent intervertebral disc herniation and an exacerbated degenerative process have been identified as the most important factors contributing to persistent pain and disability after surgical discectomy. Defects in the annulus fibrosus remain a surgical challenge, as the preference for minimally invasive surgical approaches for lumbar microdiscectomy, surgical access, and the specifics of anatomy. limit the types of devices that permit annulus fibrosus repair. Furthermore, the intervertebral disc is a relatively avascular structure, and surgical procedures can accelerate the degenerative disc process. This study aimed to evaluate the clinical safety and efficacy of a novel microdiscectomy annular repair technique combined with an autologous conditioned plasma (ACP) intradiscal injection for the treatment of lumbar disc herniation (LDH). METHODS From July 2017 to December 2018 this study recruited 75 patients with LDH (single segment) and randomly divided these patients into the following three groups: group A, full endoscopic discectomy; group B: full endoscopic discectomy and annular repair; group C, full endoscopic discectomy annular repair and ACP intradiscal injection. The pre- and postoperative neurological function and pain status were evaluated by the visual analog scale (VAS) score and the Oswestry disability index (ODI). Patients were followed up once preoperatively, and at 1, 3, and 6 months postoperatively. RESULTS The procedure was successfully performed in all cases. No cases required conversion to an open procedure. The preoperative symptoms were alleviated significantly after surgery. The VAS scores for lower back and lower limb pain and ODI score were significantly difference at 1 month, 3 months, 6 months post operation compared to pre-operation scores (P<0.05). For VAS scores of the lower back, the difference between group A and group C was statistically significant (A>C), as was the difference between group B and group C (B>C). CONCLUSIONS Early results showed that the use of the novel full endoscopic annular repair technique and ACP intradiscal injection serial therapeutic model are beneficial for short term outcomes and demonstrates a reduction in symptomatic disc reherniation with low postoperative complication rates. This new serial therapeutic model may significantly improve the symptoms of postoperative lower back pain.

Abstract

INTRODUCTION Traditional fully cemented prosthesis for total knee arthroplasty (TKA) has many disadvantages. Current studies have shown that the effects of mixed fixation TKA are the same as or even better than those of fully cemented TKA. We aimed to compare the total blood loss (TBL) in the two fixation types of TKA and the hemostatic effects of different doses of tranexamic acid (TXA) for reverse hybrid TKA. METHODS From September 2018 to November 2020, 233 patients with knee osteoarthritis undergoing unilateral TKA were randomly divided into four groups: groups 1 and 2: fully cemented TKA + intra-articular injection (IAI) of either 1 g TXA (n = 54) or 2 g TXA (n = 60); groups 3 and 4: reverse hybrid TKA + IAI of either 1 g TXA (n = 56) or 2 g TXA (n = 63). All patients were administered intravenous drip of TXA (20 mg/kg) as the basic drug. Perioperative and follow-up data of all patients were compared. RESULTS The TBL in groups 1, 2, and 3 was higher than that in group 4 (P < 0.0001). The TBL in group 1 was significantly less than that in group 3 (P < 0.05). Although there was no significant difference in blood transfusion demand among the four groups (P > 0.05), the number of anemic patients who did not meet the standard of blood transfusion in group 4 decreased significantly (P < 0.0001). There was no significant difference in pain, function or thrombotic complications among all patients. CONCLUSION The TBL in reverse hybrid TKA is larger than in fully cemented TKA. For reverse hybrid TKA, the hemostatic effect of TXA with 2 g of IAI was significantly better than with 1 g. Although this method does not reduce the need for blood transfusion, it can significantly reduce the incidence of postoperative anemia.

Abstract

PURPOSE To investigate the efficacy of non-tranexamic acid (TXA) on reducing blood loss and requirements of allogeneic blood transfusion (ABT) in total knee arthroplasty (TKA). METHODS The PubMed, EMBASE, and the Cochrane Library databases were researched since incipiency to June 2018. Only randomized controlled trials (RCTs) involved with non-TXA hemostatic techniques in TKA met the inclusion criteria. RESULTS A total of 36 RCTs, including 1511 patients, were recruited for analysis. The results of subgroup analysis revealed that hemostatic techniques, which could substantially decrease the rate of ABT, were cell salvage with the transfusion trigger of 9 mg/dl, fibrin sealant with a dosage of 10 ml, and postoperative flexion position. CONCLUSION The available evidence in this meta-analysis suggests that postoperative flexion position, fibrin sealant, and cell salvage can substantially decrease the rate of ABT in TKA. Further studies, including more hemostatic methods and high-quality research, are expected.

Abstract

OBJECTIVE Restless legs syndrome (RLS) is a common neurological disorder of unclear pathophysiology that appears to involve an iron deficiency in the brain. Some studies, but not others, suggest that intravenous injection of iron can reduce RLS severity. METHOD The databases Web of Science, PubMed, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed were searched for randomized controlled trials, cohort studies and case-control studies of intravenous iron therapy to treat RLS. Eligible studies were meta-analyzed using Stata 12.0. RESULTS This analysis indicated that IV iron was more efficacious than placebo in treating RLS (OR: 4.71,95%CI 4.21-5.21,p < 0.0001). According to sub-group analysis, either IV ferric carboxymaltose (FCM) or iron sucrose was more efficacious than placebo in treating RLS. Adverse events did not differ significantly between patients receiving intravenous iron or placebo (OR 1.68, 95%CI 0.92-3.07, p = 0.093). The present study also indicated after accepting IV iron treatment the IRLS score in RLS patients decreased (OR = 6.75,95%CI 4.02-9.49, p < 0.0001). The subgroup analysis showed that IV iron dextran, iron sucrose, and FCM could alleviate the IRLS score. CONCLUSION The available evidence suggests that intravenous iron is effective and tolerable for patients with RLS regardless of peripheral iron status.

Abstract

BACKGROUND Blood management after arthroplasties has become a serious problem. The objective is to perform a meta-analysis to compare the efficacy and safety between oral tranexamic acid (TXA) and intravenous TXA for blood management in total knee and hip arthroplasty. METHODS We systematically searched randomized controlled trials (RCTs) from Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and Google scholar. Eligibility criteria: Patients: adult patients with end-stage joint osteoarthritis, rheumatoid arthritis, and osteonecrosis of the femoral head, who prepared for TJA; Interventions: The experiential group received the intravenous form of TXA; Comparisons: Oral form of TXA; Outcomes: Total blood loss, hemoglobin reduction, transfusion requirements, duration of hospitalization, and thrombotic complications including deep vein thrombosis (DVT) and pulmonary embolism (PE); Study design: Randomized control trials (RCTs) and non-RCT. Meta-analysis results were collected and analyzed by the software STATA 11.0. After testing for heterogeneity between studies, data were aggregated for random-effects models when necessary. RESULTS Four RCTs and 2 non-RCTs were included in the meta-analysis. The present meta-analysis revealed that there were no significant differences regarding total blood loss (WMD = -25.013, 95% CI: -51.002 to 0.977, P = .059), postoperative hemoglobin decline (WMD = -0.090, 95% CI: -0.205 to 0.024, P = .122), or transfusion rate (RD = -0.039, 95% CI: -0.080 to 0.002, P = .062) between the 2 groups. CONCLUSION Oral TXA shows comparable efficacy to that of the intravenous forms after total knee and hip arthroplasty. Due to the limited quality of evidence currently available, higher quality RCTs is necessary.

Abstract

Hemorrhagic chronic radiation proctopathy (CRP) is a common complication after pelvic radiotherapy in patients with prostate or gynecological cancers. This systematic review was conducted to evaluate the efficacy and safety of argon plasma coagulation (APC) in treating hemorrhagic CRP. The databases of PubMed, Embase, and Cochrane Library were searched for related studies from inception to July 2017. Finally, 33 studies were identified with a total of 821 hemorrhagic CRP patients. After APC treatment, hemoglobin levels increased from 7.7-13.4 g/L to 11-14 g/L (including 15 studies). All (n = 33) studies reported an effective rate in rectal bleeding, among which five studies had a rate of 100%. Short-term complications were reported in 31 studies, while long-term complications in 33 studies and no complication in 11 studies. As for the severe complications, perforation was reported by 2 out of 33 studies, and the incidences were 3.3% (1/30) and 3.7% (1/27), respectively. As for APC setting, argon gas flow rate (median 1.5 L/min) and electric power (median 50 W) had no significant influence on complications and hemostasis. In conclusion, current literature indicated that APC therapy was an effective and safe strategy for hemorrhagic CRP, and large-scale prospective studies are needed to warrant our study.
