Abstract
BACKGROUND This study aimed to explore the effects of recombinant human thrombopoietin (rhTPO) on platelet recovery in decitabine, cytarabine, aclarubicin, and G-CSF (DCAG)-treated patients with intermediate-high-risk myelodysplastic syndrome/hypo proliferative acute myeloid leukemia. METHODS Recruited patients were at a ratio of 1:1 into 2 groups: the rhTPO group (DCAG + rhTPO) and control group (DCAG). The primary endpoint was the time for platelets to recover to ≥ 20 × 109/L. The secondary endpoints were the time for platelets to recover to ≥ 30 × 109/L and ≥ 50 × 109/L, overall survival (OS), and progression-free survival (PFS). RESULTS The time required for platelet recovery to ≥ 20 × 109/L, ≥30 × 109/L, and ≥ 50 × 109/L in the rhTPO group was significantly shorter (6.5 ± 2.2 vs 8.4 ± 3.1 days, 9.0 ± 2.7 vs 12.2 ± 3.9 days, 12.4 ± 4.7 vs 15.5 ± 9.3 days, respectively; all P < .05 vs controls). The amount of platelet transfusion in the rhTPO group was smaller (4.4 ± 3.1 vs 6.1 ± 4.0 U, P = .047 vs controls). The bleeding score was lower (P = .045 vs controls). The OS and PFS were significantly different (P = .009 and P = .004). The multivariable analysis showed that age, karyotype, and time for PLT recovery to ≥ 20 × 109/L were independently associated with OS. Adverse events were similar. CONCLUSIONS This study suggests that rhTPO leads to a faster platelet recovery after DCAG treatment, reduces the risk of bleeding, reduces the number of platelet transfusions, and prolongs the OS and PFS.

Abstract
OBJECTIVE To assess the efficacy of endoscopic intervention plus growth inhibitor and patient self-management in the treatment of esophagogastric variceal bleeding. METHODS Between January 2019 and December 2021, 60 patients with esophagogastric variceal bleeding treated in our hospital were assessed for eligibility and randomly recruited. They were concurrently and randomly assigned at a ratio of 1 : 1 to receive either endoscopic intervention plus growth inhibitor (control group) or endoscopic intervention plus growth inhibitor and patient self-management (observation group). The endpoint is clinical efficacy. RESULTS All eligible patients showed a similar time of hemostasis, success rate of hemostasis, rebleeding rate, and disappearance rate of varicose veins (P > 0.05). Endoscopic intervention plus growth inhibitor and patient self-management were associated with a lower incidence of complication (6.67%, including 1 (3.34%) case of ulcer and 1 (3.34%) case of fever) than endoscopic intervention plus growth inhibitor (26.67%, including 3 (10.00%) cases of ulcer, 2 (6.67%) cases of retrosternal pain, and 3 (10.00%) cases of fever) (P < 0.05). Patients in the observation group had significantly higher life satisfaction scores (25.17 ± 4.28 and 23.68 ± 5.17) than those in the control group (22.13 ± 2.24 and 18.12 ± 3.28) (P < 0.05). A decrease in life satisfaction scores was observed at 6 months after treatment, and the patients given patient self-management showed a higher satisfaction (P < 0.05). CONCLUSION Endoscopic intervention plus growth inhibitor and patient self-management yielded remarkable clinical efficacy in the treatment of esophagogastric variceal bleeding as it reduces the incidence of complication and enhances the life satisfaction of patients, and so it is worthy of clinical promotion.

International orthopaedics. 2022
Abstract
PURPOSE To investigate whether local administration of epsilon-aminocaproic acid (EACA) is effective and safe in reducing the post-operative blood loss in surgery for Sanders III-IV calcaneal fractures. METHODS Patients with Sanders III-IV calcaneal fractures who were hospitalized in our hospital from January 2016 to February 2021 and underwent open reduction internal fixation (ORIF) via lateral approach with an L-shaped incision were included in the current study. Eighty five patients were randomly divided into two groups, EACA group (43) and control group (42). Twenty milliliters of 5% EACA solution or normal saline was perfused into the incision of patients in EACA group and control group, respectively. The volume of post-operative drainage was investigated as the primary outcome. Post-operative blood test, coagulation test, and wound complications were analyzed as the secondary outcomes. RESULTS The volume of post-operative drainage at 24 and 48 h was 164.8 ± 51.4 ml, 18.9 ± 3.8 ml for patients in EACA group, and 373.0 ± 88.1 ml, 21.2 ± 4.4 ml for patients in the control group, respectively. EACA greatly reduced the post-operative blood loss compared to the control (normal saline). The difference between the two groups was statistically significant. No statistically significant difference was found between EACA group and control group with regard to the pre-operative, baseline characteristics. Post-operative blood test results demonstrated that haemoglobin and hematocrit were significantly higher in EACA compared to those of control group. No significant difference was found between EACA group and control group in terms of the platelet counts, prothrombin time (P.T.), activated partial prothrombin time (APTT), and wound complications. CONCLUSION Local administration of EACA is effective in post-operative blood loss reduction in ORIF surgeries for Sanders III-IV types of calcaneal fractures without increasing the incidence of periwound complication.

Laryngoscope investigative otolaryngology. 2022;7(4):1206-1216
Abstract
OBJECTIVE This study was to compare tonsillectomy with intraoperative suturing (TIS) and tonsillectomy without intraoperative suturing (TsIS) in preventing postoperative tonsillectomy hemorrhage (PTH). METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was followed. Articles compare TIS and TsIS in preventing PTH were included. The quality of eligible studies was assessed with the Newcastle-Ottawa Scale (NOS) by two independent investigators. Random effect models were used to determine odds ratio (OR) with 95% CIs. RESULTS A total of 15 studies were analyzed. The pooled results showed the PTH rate was lower in the TIS group (OR = 0.64; 95% CI, 0.47-0.88). The TIS group had a lower primary and secondary PTH rate than the TsIS group with OR values of 0.44 (95% CI, 0.30-0.64) and 0.70 (95% CI, 0.54-0.90), respectively. However, suturing did not show an advantage in reducing the risk of returning to the operation room for hemostasis (OR = 0.57; 95% CI, 0.13-2.47). Adults might benefit from the intraoperative suturing procedure (OR = 0.31; 95% CI, 0.16-0.60). Patients with more than three stitches on each side had a lower PTH rate (OR: 0.44; 95% CI, 0.32-0.60). Suturing the tonsillar fossa and pillars simultaneously could reduce the PTH rate (OR = 0.47; 95% CI, 0.34-0.64). CONCLUSIONS Intraoperative suturing is a good strategy for preventing PTH. More multicenter randomized controlled studies should be conducted to demonstrate the efficacy of this procedure. LEVEL OF EVIDENCE 5.

BMC pregnancy and childbirth. 2022;22(1):160
Abstract
BACKGROUND The guidelines of National Health Service(NHS, the United Kingdom) recommended for use in obstetrics at increased risk of bleeding, requiring two suction devices to reduce amniotic fluid contamination, however, when comes to massive hemorrhage, it is may difficult to operate because the complex operation may delay time. The aim of the study was to detect the effect of amniotic fluid recovery on intraoperative cell salvage in obstetrics and provide evidence for clinical applications. METHOD Thirty-four patients undergoing elective cesarean section were randomly divided into two groups. In group 1, the cumulative blood from the operation field, including the amniotic fluid, was collected using a single suction device for processing. In group 2, after suctioning away the amniotic fluid using another suction device for the cumulative blood from the operation field. From each group, four samples were taken, including maternal venous blood (sample I), blood before washing (sample II), blood after washing (sample III) and blood after filtration with a leukocyte filter (sample IV), to detect serum potassium (K +), hemoglobin (Hb), white blood cell (WBC), fetal hemoglobin (HbF), alpha fetoprotein (AFP) and squamous cell (SC) levels. RESULTS The AFP, K + and WBC levels of sample III and sample IV were significantly lower than sample I in group 1 and group 2 (P < 0.05). Significantly more SCs were found in sample III than in sample I in group 1 and group 2 (P < 0.05), but SCs of sample IV had no statistical difference compared to sample I in group 1 and group 2 (P > 0.05). There was no significant difference in the K + , Hb, WBC, AFP and SC levels of sample IV between group 1 and group 2 (P > 0.05). The HbF levels of sample III and sample IV were significantly higher in group 1 than in group 2 (P < 0.05). CONCLUSION There is little or no possibility for AF contamination to enter the re-infusion system when used in conjunction with a leucodepletion filter. For maternal with Rh-negative blood, we recommend two suction devices to reduce HbF pollution. TRIAL REGISTRATION ChiCTR1800015684 , 2018.4.15.

Indian journal of orthopaedics. 2021;55(Suppl 2):418-425
Abstract
PURPOSE To investigate whether local administration of tranexamic acid (TXA) is effective in postoperative blood loss reduction in surgeries for Sanders III-IV calcaneal fractures. METHODS Calcaneal fracture patients who were hospitalized in our hospital from August 2014 to April 2018 and underwent open reduction internal fixation (ORIF) via lateral approach with an L-shaped incision were included in the present study. 53 Patients were randomly divided into three groups, groups A (17), B (17) and C (19). Twenty milliliters of 10 mg/ml and 20 mg/ml TXA solution were perfused into the incision of patients in group A and group B, respectively. Twenty milliliters of saline were perfused into the incision of patients in group C as control. The volume of postoperative drainage, postoperative blood test, coagulation test, and wound complications were analyzed to evaluate the effectiveness of local administration of TXA on blood loss reduction. RESULTS The amount of drainage at 24 and 48 h after the procedure was 110 ± 170, 30 ± 10 ml and 130 ± 160, 20 ± 17 ml for patients in group A and group B, respectively. The corresponding numbers for patients in group C were 360 ± 320, 20 ± 10 ml. The difference between group A and group C was statistically significant, so was the difference between group B and group C. No statistically significant difference was found between group A and group B. Postoperative blood test results revealed that the levels of hemoglobin and hematocrit were significantly higher in group A and group B when each compared to that of group C. In contrast, no difference was found between group A and group B. No significant difference was found between each experimental group and the control group in terms of platelet counts, prothrombin time (P.T.), activated partial prothrombin time (APTT), and wound complications. CONCLUSION Local administration of TXA is effective in the reduction of postoperative blood loss in surgeries for Sanders III-IV types of calcaneal fractures without notably associated side effects.

International journal of stroke : official journal of the International Stroke Society. 2021;:17474930211006580
Abstract
Background Remote ischemic conditioning (RIC) can promote hematoma resolution, attenuate brain edema, and improve neurological recovery in animal models of intracerebral hemorrhage (ICH). Aims This study aimed to evaluate the safety and preliminary efficacy of RIC in patients with ICH.Methods In this multicenter, randomized, controlled trial, 40 subjects with supratentorial ICH presenting within 24-48 hours of onset were randomly assigned to receive medical therapy plus RIC for consecutive 7 days or medical therapy alone. The primary safety outcome was neurological deterioration within 7 days of enrollment, and the primary efficacy outcome was the changes of hematoma volume on CT images. Other outcomes included hematoma resolution rate at 7 d ([hematoma volume at 7 d â hematoma volume at baseline]/hematoma volume at baseline), perihematomal edema (PHE), and functional outcome at 90 days. Results The mean age was 59.3±11.7 years and hematoma volume was 13.9±4.5 mL. No subjects experienced neurological deterioration within 7 days of enrollment, and no subject died or experienced RIC-associated adverse events during the study period. At baseline, the hematoma volumes were 14.19±5.07 mL in the control group and 13.55±3.99 mL in the RIC group, and they were 8.54±3.99 mL and 6.95±2.71 mL at 7 days after enrollment, respectively, not a significant difference (p>0.05 each). The hematoma resolution rate in the RIC group (49.25±9.17%) was significantly higher than in the control group (41.92±9.14%; MD, 7.3%; 95% CI, 1.51% to 13.16%; p=0.015). The absolute PHE volume was 17.27±8.34 mL in the control group and 12.92±7.30 mL in the RIC group at 7 days after enrollment, not a significant between-group difference (p=0.087), but the relative PHE in the RIC group (1.77±0.39) was significantly lower than in the control group (2.02±0.27; MD, 0.25; 95% CI, 0.39-0.47; p=0.023). At 90-day follow-up, 13 subjects (65%) in the RIC group and 12 subjects (60%) in the control group achieved favorable functional outcomes (mRS scoreâ¤3), not a significant between-group difference (p=0.744).Conclusions Repeated daily RIC for consecutive 7 days was safe and well-tolerated in patients with ICH, and it may be able to improve hematoma resolution rate and reduce relative PHE. However, effects RIC on the absolute hematoma and PHE volume and functional outcomes in this patient population need further investigations.Clinical Trial Registration URL: http://www.clinicaltrials.gov.

Preradiosurgery embolization in reducing the postoperative hemorrhage rate for patients with cerebral arteriovenous malformations: a systematic review and meta-analysis
Jiang X, Zhao Z, Zhang Y, Wang Y, Lai L
Neurosurgical review. 2021
Abstract
Few studies have examined the postoperative hemorrhage rate of cerebral arteriovenous malformations (AVMs) treated by embolization prior to stereotactic radiosurgery. The objective of this analysis was to compare the postoperative hemorrhage rate between AVMs treated with and those treated without preradiosurgery embolization. A systematic search of the PubMed and Embase databases was performed with no restriction on the publication period. Based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we included studies with sufficient baseline and outcome data. The analysis was performed using Comprehensive Meta-Analysis (CMA) 2.0. Eleven studies comprising 2591 patients were eligible for analysis. There was no significant difference in the postoperative hemorrhage rate between patients who had undergone embolization followed by SRS and those who had undergone SRS alone (OR 1.140, 95% CI 0.851-1.526, p = 0.38). The obliteration rate was significantly lower in the E + SRS group than in the SRS group (OR 0.586, 95% CI 0.398-0.863, p = 0.007). No significant difference in permanent neurological deficits was identified between patients who had undergone embolization followed by SRS and those who had undergone SRS alone (OR 1.175, 95% CI 0.626-2.206, p = 0.616). Available data suggested that preradiosurgery embolization did not reduce the postoperative hemorrhage rate and resulted in a significantly lower obliteration rate than treatment with SRS alone.

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.

Huang QS, Liu Y, Wang JB, Peng J, Hou M, Liu H, Feng R, Wang JW, Xu LP, Wang Y, et al
The Lancet. Haematology. 2021;8(10):e688-e699
Abstract
BACKGROUND High-dose dexamethasone is the standard initial treatment for patients with immune thrombocytopenia, but many patients still relapse and require further treatments. All-trans retinoic acid has been shown to exert immunomodulatory effects and promote thrombopoiesis, and so we aimed to assess the activity and safety of all-trans retinoic acid plus high-dose dexamethasone as a first-line treatment for newly diagnosed patients with immune thrombocytopenia. METHODS This multicentre, open-label, randomised, controlled, phase 2 trial was done at six different tertiary medical centres in China. Eligible participants were adults (aged >18 years) with treatment-naive, newly diagnosed, primary immune thrombocytopenia who had either a platelet count of less than 30 × 10(9) platelets per L or a platelet count of less than 50 × 10(9) platelets per L and clinically significant bleeding. We randomly assigned (1:1) participants to receive either all-trans retinoic acid (10 mg orally twice daily for 12 weeks) plus high-dose dexamethasone (40 mg/day intravenously for 4 consecutive days) or high-dose dexamethasone alone using a central, web-based randomisation system. If patients did not respond by day 14, the 4-day course of dexamethasone was repeated. The primary endpoint was 6-month sustained response, defined as the maintenance of a platelet count of at least 30 × 10(9) platelets per L and at least 2-times higher than the baseline count and the absence of bleeding, with no need for rescue medication at this time. The primary endpoint was analysed by intention-to-treat and safety was assessed in all participants who received at least one dose of the study drug. This trial is registered with ClinicalTrials.gov, NCT04217148, and is now completed. FINDINGS Between Jan 1, 2020, and June 30, 2020, 132 patients were randomly assigned to either all-trans retinoic acid plus high-dose dexamethasone (n=66) or high-dose dexamethasone alone (n=66). Three patients did not receive their allocated treatment, leaving 129 in the safety analysis set. At 6 months, a significantly higher proportion of participants in the all-trans retinoic acid plus high-dose dexamethasone group (45 [68%] of 66) than in the high-dose dexamethasone monotherapy group (27 [41%] of 66) had a sustained response (OR 3·095, 95% CI 1·516-6·318; p=0·0017). The most common adverse events were dry skin (31 [48%] of 64 patients), headaches (12 [19%]), and insomnia (12 [19%]) in the combination group, and insomnia (ten [15%] of 65 patients) and anxiety or mood disorders (eight [12%]) in the monotherapy group. Both treatments were well tolerated and no grade 4 or worse adverse events occurred. There were no treatment-related deaths. INTERPRETATION The combination of all-trans retinoic acid and high-dose dexamethasone was safe and active in newly diagnosed patients with primary immune thrombocytopenia, providing a sustained response. This regimen represents a potential first-line treatment in this setting, but further studies are needed to validate its efficacy and safety.
