Abstract
OBJECTIVE This systematic review and network meta-analysis aimed to assess the relative efficacy of currently multiple hemostatic modalities in nonvariceal gastrointestinal bleeding (NVGIB). BACKGROUND Nonvariceal gastrointestinal bleeding is a frequent medical condition with significant mortality and morbidity. There are currently multiple hemostatic modalities, but their relative efficacy is still unknown. METHODS Major databases including PubMed, EMBASE and the Cochrane Library were searched for studies that compared the relative efficacy of different hemostatic techniques for NVGIB (over-the-scope-clip (OTSC), hemostatic powder (HP) and conventional endoscopic treatment (CET)). The 30-day rebleeding rate was the primary outcome. We performed pairwise and network meta-analyses for all treatments. The heterogeneity and transitivity were evaluated. RESULTS Twenty-two studies were included. OTSC and HP + CET showed superior efficacy compared with CET (OTSC vs CET: RR, 0.42 [95% CI, 0.28-0.60]; HP + CET vs CET: RR, 0.40 [95% CI, 0.17-0.87]) while their relative efficacy had not detected any statistically significant difference (OTSC vs HP + CET: RR, 0.95 [95% CI, 0.38-2.31]) in the 30-day rebleeding rate. HP + CET was ranked highest in the network ranking estimate. In addition, the sensitivity analysis showed that it was not robust that OTSC was superior to CET in the short-term rebleeding rate and the initial hemostasis rate. None of the other comparisons found a statistically significant difference. CONCLUSIONS This systematic review and network meta- analysis showed that OTSC and HP + CET significantly reduced 30-day rebleeding rates compared to CET and had similar efficacy.

Xiong Y, Guo X, Huang X, Kang X, Zhou J, Chen C, Pan Z, Wang L, Goldbrunner R, Stavrinou L, et al
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.

Orthopaedic surgery. 2022
Abstract
This study aimed to evaluate the efficiency and safety of tranexamic acid for blood management during high tibial osteotomy (HTO). A systematic search was conducted in Medline, Embase, and the Cochrane library database. Six studies and 208 patients were included in this meta-analysis using Review Manager V.5.3 and Stata 15.1 software. For primary outcomes, tranexamic acid lowered the total blood loss (WMD = -219.47, 95% CI [-355.61, -83.33], P = 0.002). For secondary outcomes, a significant reduction was found for decreased hemoglobin (POD1: WMD = -9.86, 95% CI [-13.45, -6.28], P < 0.05; POD2: WMD = -8.41, 95% CI [-11.50, -5.32], P < 0.05; POD5: WMD = -11.48, 95% CI [-14.56, -8.39], P < 0.05) and drainage (total: WMD = -105.93, 95% CI [-187.08, -24.78], P < 0.05; POD1: WMD = -122.195, 95% CI [-168.902, -75.488], P < 0.05). The sex difference (male/female ratio) was determined (total blood loss: P = 0.025; total drainage amount: p = 0.018) using meta-regression analysis. Females benefited more from tranexamic acid in terms of total blood loss (M/F > 40%: WMD = -53.11, 95% CI [-100.16, -6.05], P = 0.03; 40% ≥ M/F ≥ 20%: WMD = -362.20, 95% CI [-423.96, -300.45], P < 0.05; M/F < 20%: WMD = -263.00, 95% CI [-277.17, -248.83], P < 0.05) and total drainage (M/F > 40%: WMD = -7.11, 95% CI [-10.75, -3.47], P < 0.05; 40% ≥ M/F ≥ 20%: WMD = -104.72, 95% CI [-155.36, -54.08], P < 0.05; M/F < 20%: WMD = -222.00, 95% CI [-297.42, -146.58], P < 0.05). No significant differences were found for drainage on POD2 and POD3, wound complications, orthromboembolic events. In conclusion, tranexamic acid is effective and safe for blood management during HTO. Females appeared to benefit more from it, and an additional postoperative dose is suggested fora better effect.

Computational and mathematical methods in medicine. 2022;2022:5648918
Abstract
OBJECTIVE To study the effect of Mirena intrauterine device (IUD) on endometrial thickness, life quality score, and curative effect in patients with perimenopausal abnormal uterine bleeding. METHODS Eighty patients with perimenopausal abnormal uterine bleeding cured from January 2020 to December 2021 were enrolled as the object of study. According to random number table, the patients were classified into the study (n = 40) and control (n = 40) groups. The control cases were cured with medroxyprogesterone. The study cases were cured with Mirena IUD. The effective rate of clinical therapies was evaluated after 3 months of treatment. The endometrial thickness, menstrual volume score, and life quality score (WHOQOL-BREF) was measured after 1 month, 2 months, and 3 months of treatment. RESULTS The effective rate of patients with Mirena IUD for 3 months was higher compared to the control group (P < 0.05). The endometrial thickness and menstrual volume scores of study cohort after 1 month, 2 months, and 3 months following treatment were remarkably lower than those before treatment (P < 0.05) and were considerably lower than those of control cohort (P < 0.05). The hemoglobin level of the studied cases after 1 month, 2 months, and 3 months after therapy was remarkably upregulated (P < 0.05) and was greatly higher compared to the controlled cases (P < 0.05). After 3-month treatment, the WHOQOL-BREF score of the study group was higher compared to the control group (P < 0.05). CONCLUSION The Mirena IUD is far more effective in the treatment of perimenopausal abnormal uterine bleeding and is helpful in reducing the thickness of the endometrium. Patients' menstrual flow can be controlled, and anemia can be corrected; thus, patients improve their quality of life and health status and can be considered for further promotion.

Abstract
Postpartum hemorrhage (PPH) can lead to substantial blood loss that compromises maternal hemodynamic stability and consequently cause severe maternal complications such as organ dysfunction or death. Intraoperative cell salvage (IOCS), an effective method of blood conservation used in other surgical specialties, can be an alternative intervention for managing PPH. Thus, our aim was to evaluate the efficacy and safety of IOCS for women at high risk of PPH undergoing cesarean sections. We conducted a systematic search of electronic databases from inception to February 25, 2021 for randomized controlled studies and observational studies published in English or Mandarin about IOCS use in cesarean sections. Primary outcomes of interest were changes in postoperative hematologic parameters and any adverse events reported among patients that had IOCS and controls that had an allogeneic blood transfusion. The certainty of the evidence of the outcomes was evaluated using the GRADE approach. A total of 24 studies with 5872 patients were included in the meta-analysis. Eleven randomized controlled trials (RCTs), and 13 observational studies were analyzed. Postoperative hemoglobin levels were higher among patients with IOCS SMD 0.39 (95% CI; 0.20, 0.60; P < 0.001, high certainty). Allogeneic blood transfusion increased adverse events RR = 1.81(95% CI; 1.24, 2.62; P = 0.002, low certainty). IOCS shortened hospital stay SMD - 0.59 (95% CI: - 0.98, - 0.19; P = 0.004, low certainty) and shortened prothrombin time SMD - 0.67 (95% CI; - 1.31, - 0.04), P = 0.037, low certainty). The lower incidence of transfusion-related adverse events and shorter hospital stay among other findings demonstrate that IOCS use in obstetrics is an effective and safe alternative for the management of PPH; however, high-quality randomized control studies are required to confirm this evidence.

Neurosurgical review. 2022
Abstract
To summarize and analyze the clinical efficacy and safety of neuroendoscopic surgery (NES) in the treatment of patients for severe thalamic hemorrhage with ventricle encroachment (THVE). Eighty-three patients with severe THVE were treated in the Neurosurgery Department of Anqing Hospital Affiliated to Anhui Medical University from July 2019 to August 2021. Our study was approved by the ethics committee. The patients were randomly divided into NES group and extraventricular drainage (EVD) group. The hospital stay, Glasgow coma scale (GCS) scores on the 1st and 14th days postoperatively, the incidence of intracranial infections, and the clearance of postoperative hematomas were compared and analyzed between the two groups. The patients had follow-up evaluations 6 months postoperatively. The prognosis was evaluated based on the activity of daily living (ADL) score. A head CT or MRI was obtained to determine whether there was hydrocephalus, cerebral infarction, or other related complications. Eighty-three patients were randomly divided into 41 cases of NES group and 42 cases of EVD group. The length of postoperative hospital stay was 17.42 ± 1.53 days, the GCS scores were 6.56 ± 0.21, and 10.83 ± 0.36 on days 1 and 14, respectively; intracranial infections occurred in 3 patients (7.31%) and the hematoma clearance rate was 83.6 ± 5.18% in the NES group, all of which were significantly better than the EVD group (P < 0.05). After 6 months of follow-up, 28 patients (68.29%) had a good prognosis, 5 patients (12.19%) died, and 4 patients (9.75%) had hydrocephalus in the NES group. In the EVD group, the prognosis was good in 15 patients (35.71%), 12 patients (28.57%) died, and 17 patients (40.47%) had hydrocephalus. The prognosis, mortality rate, and incidence of hydrocephalus in the NES group were significantly better than the EVD group (P < 0.05). Compared to traditional EVD, NES for severe THVE had a higher hematoma clearance rate, and fewer intracranial infections and patients with hydrocephalus, which together improve the clinical prognosis and is thus recommended for clinical use.

Controlled Hypotension Combined with Femoral Nerve Block for Knee Replacement without Tourniquet
Wang L, Zheng Y, Zhang X, Ke Q
Journal of healthcare engineering. 2021;2021:3219337
Abstract
In the process of knee replacement surgery, the use of tourniquet technology for hemostasis is the most common method. But the adverse reactions of tourniquets in knee replacement surgery have become more prominent in recent years. More and more scholars have begun to advocate the optimization of the use of tourniquet technology, thereby controlling the use of tourniquet technology. In this study, 125 patient cases were randomly divided into four experimental groups for comparative analysis. The two sets of variables are whether to use tourniquet during surgery and use intravenous analgesia or nerve block analgesia. Studies have shown that when using a tourniquet for knee replacement surgery, the chance of hidden blood loss increases after use. The tourniquet was not used during the operation, the patient's thighs were swollen, and postoperative pain was reduced. Compared with intravenous analgesia, knee joint replacement with uncontrolled tourniquet combined with femoral nerve block has a better analgesic effect and can effectively relieve pain after knee replacement. Therefore, under the method of controlled hypotension combined with femoral nerve block, TKA surgery without using tourniquet technology is more conducive to early health recovery and pain relief after TKA surgery, as well as functional exercise and knee joint recovery during postoperative recovery.

Abstract
Thrombopoietin receptor agonists (TPO-RAs) play a crucial role in stimulating thrombopoiesis. However, conventional meta-analyses have shown inconsistent results regarding the efficacy of thrombopoietin receptor agonists versus placebo. Therefore, we performed a network meta-analysis to assess the effects of five TPO-RAs via indirect comparison. For this network meta-analysis, we considered randomized trials that included any of the following interventions: avatrombopag, lusutrombopag, eltrombopag, romiplostim, recombinant human thrombopoietin (rhTPO). We searched the Medline, PubMed, Embase, the Cochrane Library, and Web of Science databases for randomized controlled clinical trials from inception to January 31, 2021. We use randomized controlled clinical trials of TPO-RAs for treatment of immune thrombocytopenia in adults. The primary outcome was the number of patients achieving platelet response which was defined as the achievement of a platelet count of more than 30 or 50 cells × 10(9)/L in the absence of rescue therapy, and the secondary outcome was the therapy-related serious adverse events and incidence of bleeding episodes. To obtain the estimates of efficacy and safety outcomes, we performed a random-effects network meta-analysis. These estimates were presented as odds ratios with 95% confidence intervals. We use surface under the cumulative ranking probabilities to rank the comparative effects and safety of all drugs against the placebo. In total, 2,207 patients were analyzed in 20 clinical trials. All preparations improved the point estimates of platelet response when compared with the placebo. Avatrombopag and lusutrombopag had the best platelet response compared to the placebo, the former had a non-significant advantage compared to the latter [odds ratio (OR) = 1.91 (95% confidence interval: 0.52, 7.05)]. The treatments were better than eltrombopag, romiplostim, rituximab, and rhTPO + rituximab, with corresponding ORs of 3.10 (1.01, 9.51), 9.96 (2.29, 43.29), 33.09 (8.76, 125.02), and 21.31 (3.78, 119.98) for avatrombopag and 1.62 (0.63, 4.17), 5.21 (1.54, 17.62), 17.34 (5.15, 58.36), and 11.16 (2.16, 57.62) for lusutrombopag. Regarding bleeding, the placebo group had the highest probability of bleeding, whereas lusutrombopag had the lowest risk of bleeding when compared to the placebo. Adverse events were slightly higher in patients receiving rituximab than in those receiving placebo or other treatments. Overall, this meta-analysis showed that avatrombopag may yield the highest efficacy because it has the most favorable balance of benefits and acceptability.

Wang Y, Yao W, Wang L, Xv D
American journal of translational research. 2021;13(8):9578-9585
Abstract
OBJECTIVE This study explored and analyzed the effects of butylphthalide injection on the cognitive function and on the TLRs/NF-κB pathway in hypertensive intracerebral hemorrhage patients. METHODS A total of 115 patients admitted to our hospital with hypertensive intracerebral hemorrhages were recruited as the study cohort and randomly placed in the observation group (n=60) or the control group (n=55). In addition to the routine treatment administered in both groups, the control group was additionally administered oral nimodipine tablets, and the observation group was administered intravenous butylphthalide injections. Both groups were treated continuously for 14 days. Subsequently, the changes in the clinical efficacy, the NIHSS scores, the extremity motor function, the Fugl-Meyer scores, the blood-brain barrier (BBB) and the peripheral blood mononuclear cells (PBMCs), the TLR2, TLR9, and the NF-κB mRNA levels in the two groups before and after the treatment were compared, and any adverse reactions were observed. RESULTS The total effective rate in the observation group was significantly superior to the total effective rate in the control group (P<0.05). The post-treatment NIHSS scores in the two groups were dramatically lower (P<0.05), and the post-treatment scores in the observation group were significantly lower than they were in the control group (P<0.05). The post-treatment cerebral spinal fluid (CSF) albumin and BBB indexes in the two groups were decreased significantly compared to their pre-treatment levels (P<0.05), and the post-treatment indexes in the observation group were significantly lower than the post-treatment indexes in the control group (P<0.05). The post-treatment relative TLR2, TLR9, and NF-κB mRNA expressions in the two groups were apparently lower than their in pre-treatment levels (P<0.05), and the relative expressions in the observation group after the treatment were clearly lower than they were in the control group (P<0.05). CONCLUSION Butylphthalide injection has a high clinical efficacy in treating hypertensive intracerebral hemorrhages. The drug can effectively improve patients' cognitive functions, extremity motor functions, and BBB indexes, and its mechanism may connect with the expressive suppression of the TLRs/NF-κB signaling pathway. The treatment is safe and effective, so it is worthy of clinical promotion.

Abstract
Objective: The aim of this study was to perform a systematic review and meta-analysis to assess whether cerebral small vessel disease (CSVD) on neuroimaging of patients with acute ischemic stroke (AIS) treated with intravenous thrombolysis (IVT) is associated with an increased risk of hemorrhagic transformation (HT), symptomatic intracranial hemorrhage (sICH), and poor functional outcome (PFO). Methods: A thorough search of several databases was carried out to identify relevant studies up to December 2020. We included studies of patients with AIS and neuroimaging markers of CSVD treated with IVT. The primary outcome was HT, and the secondary outcomes were sICH and 3-month PFO. The quality of the studies involved was evaluated using the Newcastle-Ottawa Scale (NOS). The meta-analysis with the fixed effects model was performed. Results: Twenty-four eligible studies (n = 9,419) were pooled in the meta-analysis. All included studies were regarded as high quality with the NOS scores of at least 6 points. The meta-analysis revealed associations between the presence of CSVD and HT, sICH, and the 3-month PFO after IVT. Compared with no CSVD, the presence of CSVD was associated with an increased risk of HT (OR: 1.81, 95% CI: 1.52-2.16), sICH (OR: 2.42, 95% CI: 1.76-3.33), and 3-month PFO (OR: 2.15, 95% CI: 1.89-2.44). For patients with AIS complicated with CSVD, compared with a CSVD score of 0-1, a CSVD score of 2-4 was associated with an increased risk of HT (OR: 3.10, 95% CI: 1.67-5.77), sICH (OR: 2.86, 95% CI: 1.26-6.49), and 3-month PFO (OR: 4.58, 95% CI: 2.97-7.06). Conclusion: Patients with AIS complicated with neuroimaging markers of CSVD are at increased risk of HT and 3-month PFO after IVT. However, it is still necessary to clarify the exact role of CSVD in the occurrence, development, and prognosis of AIS.
