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
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.

Abstract
BACKGROUND Convalescent plasma has been one of the most common treatments for COVID-19, but most clinical trial data to date have not supported its efficacy. RESEARCH QUESTION Is rigorously selected COVID-19 convalescent plasma with neutralizing anti-SARS-CoV-2 antibodies an efficacious treatment for adults hospitalized with COVID-19? STUDY DESIGN AND METHODS This was a multicenter, blinded, placebo-controlled randomized clinical trial among adults hospitalized with SARS-CoV-2 infection and acute respiratory symptoms for <14 days. Enrolled patients were randomly assigned to receive one unit of COVID-19 convalescent plasma (n=487) or placebo (n=473). The primary outcome was clinical status (illness severity) 14 days after study infusion measured with a seven-category ordinal scale ranging from discharged from the hospital with resumption of normal activities (lowest score) to death (highest score). The primary outcome was analyzed with a multivariable ordinal regression model, with an adjusted odds ratio (aOR) <1.0 indicating more favorable outcomes with convalescent plasma than placebo. In secondary analyses, trial participants were stratified by the presence of endogenous anti-SARS-CoV-2 antibodies ("serostatus") at randomization. The trial included 13 secondary efficacy outcomes, including 28-day mortality. RESULTS Among 974 randomized patients, 960 were included in the primary analysis. Clinical status on the ordinal outcome scale at 14 days did not differ between the convalescent plasma and placebo groups in the overall population (aOR: 1.04; 1/7 support interval (SI): 0.82-1.33), in patients without endogenous antibodies (aOR: 1.15; 1/7 SI: 0.74-1.80), or in patients with endogenous antibodies (aOR: 0.96; 1/7 SI: 0.72-1.30). None of the 13 secondary efficacy outcomes were different between groups. At 28 days, 89/482 (18.5%) patients in the convalescent plasma group and 80/465 (17.2%) patients in the placebo group had died (aOR: 1.04, 1/7 SI: 0.69-1.58). INTERPRETATION Among adults hospitalized with COVID-19, including those seronegative for anti-SARS-CoV-2 antibodies, treatment with convalescent plasma did not improve clinical outcomes.

Frontiers in medicine. 2022;9:772954
Abstract
BACKGROUND For patients with obscure gastrointestinal bleeding (OGIB), finding the bleeding site is challenging. Balloon-assisted enteroscopy (BAE) has become the preferred diagnostic modality for OGIB. The long-term outcome of patients with negative BAE remains undefined. The present study aimed to evaluate the long-term outcomes of patients with negative BAE results for OGIB and to clarify the effect of further investigations at the time of rebleeding with a systematic review and meta-analysis of the available cohort studies. METHODS Studies were searched through the PubMed, EMBASE, and Cochrane library databases. The following indexes were analyzed: rebleeding rate after negative BAE, rebleeding rate after different follow-up periods, the proportion of patients who underwent further evaluation after rebleeding, the percentage of patients with identified rebleeding sources, and the percentage of patients with rebleeding sources in the small intestine. Heterogeneity was assessed using the I(2) test. RESULTS Twelve studies that involved a total of 407 patients were included in the analysis. The pooled rebleeding rate after negative BAE for OGIB was 29.1% (95% CI: 17.2-42.6%). Heterogeneity was significant among the studies (I(2) = 88%; p < 0.0001). The Chi-squared test did not show a difference in rebleeding rates between the short and long follow-up period groups (p = 0.142). The pooled proportion of patients who underwent further evaluation after rebleeding was 86.1%. Among the patients who underwent further evaluation, rebleeding sources were identified in 73.6% of patients, and 68.8% of the identified rebleeding lesions were in the small intestine. CONCLUSION A negative result of BAE in patients with OGIB indicates a subsequently low risk of rebleeding. Further evaluation should be considered after rebleeding.

Zheng X, Gao F, Wang L, Meng Y, Ageno W, Qi X
Journal of thrombosis and thrombolysis. 2022
Abstract
Coronavirus disease 2019 (COVID-19) and COVID-19 vaccination may cause splanchnic vein thrombosis (SVT), which is potentially fatal. The present study aims to pool the incidence and outcomes of SVT patients with COVID-19 or having received COVID-19 vaccines. The PubMed, EMBASE, and Cochrane databases were searched. Based on the data from cohort studies, meta-analyses were performed to evaluate the incidence of SVT in COVID-19 patients or people having received COVID-19 vaccines. Pooled proportions were calculated. Based on the individual data from case reports, logistic regression analyses were performed to identify factors associated with death in SVT patients. Odds ratios (ORs) were calculated. Among 654 papers initially identified, 135 were included. Based on 12 cohort studies, the pooled incidence of SVT in COVID-19 patients was 0.6%. Data were insufficient to estimate the incidence of SVT after COVID-19 vaccination. Based on 123 case reports, the mortality was 14% (9/64) in SVT patients with COVID-19 and 25% (15/59) in those who received COVID-19 vaccines. Univariate analyses demonstrated that age (OR = 1.061; p = 0.017), diabetes mellitus (OR = 14.00; p = 0.002), anticoagulation (OR = 0.098; p = 0.004), and bowel resection (OR = 16.00; p = 0.001) were significantly associated with death in SVT patients with COVID-19; and anticoagulation (OR = 0.025; p = 0.003) and intravenous immunoglobulin (OR = 0.175; p = 0.046) were significantly associated with death in SVT patients who received COVID-19 vaccines. Multivariate analyses did not identify any independent factor for death in both patients. SVT in COVID-19 patients and in subjects who received COVID-19 vaccines carries a high mortality, but may be improved by anticoagulation. PROSPERO Identifier CRD42022315254.

Wideochirurgia i inne techniki maloinwazyjne = Videosurgery and other miniinvasive techniques. 2022;17(4):611-623
Abstract
INTRODUCTION Due to the complicated surgical procedure of knee arthroplasty and low effectivity of hyaluronic acid (HA) in the treatment of knee osteoarthritis, various studies highly recommend the use of platelet-rich plasma (PRP). However, some studies also reported lower efficacy and limited use of PRP. AIM: To analyze systematically the different randomized controlled trials (RCTs) comparing the effectiveness of HA vs. PRP for the treatment of knee osteoarthritis. MATERIAL AND METHODS A systematic literature review was conducted using Medline and Central databases for RCTs about the comparison of HA vs. PRP for the treatment of knee osteoarthritis. Studies were included as per the PICOS criteria and relevant event data were extracted. Risk of bias was analyzed and a random-effects model was used to calculate the pooled odds ratio and risk ratio using RevMan software. RESULTS A total of 14 studies were included in the meta-analysis from year 2000 to 2021 including 613 patients. The current meta-analysis has a low risk of publication bias and we obtained the pooled odds ratio (OR) of 2.55 (95% CI: 1.35-4.84) with a τ (2) value of 1.01, χ (2) value of 52.79, I(2) value of 77%, Z value of 2.87 and p-value < 0.00001. The pooled risk ratio was 1.34 (95% CI: 1.09-1.65) with a τ (2) value of 0.09, χ (2) value of 73.48, I(2) value of 84%, Z value of 2.80 and p-value < 0.00001. CONCLUSIONS The current meta-analysis highly recommends the use of PRP for the treatment of knee osteoarthritis.

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.

Use of Human Albumin Administration for the Prevention and Treatment of Hyponatremia in Patients with Liver Cirrhosis: A Systematic Review and Meta-Analysis
Bai Z, Wang L, Lin H, Tacke F, Cheng G, Qi X
Journal of clinical medicine. 2022;11(19)
Abstract
BACKGROUND Hyponatremia is a common complication of liver cirrhosis and aggravates patients' outcomes. It may be corrected by human albumin (HA) infusion. Herein, we have conducted a systematic review and meta-analysis to evaluate the efficacy of intravenous HA administration for the prevention and treatment of hyponatremia in liver cirrhosis. METHODS Literature was searched in the PubMed, EMBASE, and Cochrane Library databases. If possible, a meta-analysis would be conducted. Incidence of hyponatremia, rate of resolution of hyponatremia, and serum sodium level were compared between cirrhotic patients who received and did not receive HA infusion. Odds ratios (ORs) or mean differences (MDs) with 95% confidence intervals (CIs) were calculated. The quality of evidence was assessed by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS Initially, 3231 papers were identified. Among them, 30 studies, including 25 randomized controlled trials (RCTs) and 5 cohort studies, were eligible. Among cirrhotic patients without hyponatremia, the HA infusion group had significantly lower incidence of hyponatremia (OR = 0.55, 95%CI = 0.38-0.80, p = 0.001) and higher serum sodium level (MD = 0.95, 95%CI = 0.47-1.43, p = 0.0001) as compared to the control group. Among cirrhotic patients with hyponatremia, the HA infusion group had a significantly higher rate of resolution of hyponatremia (OR = 1.50, 95%CI = 1.17-1.92, p = 0.001) as compared to the control group. Generally, the quality of available evidence is low. CONCLUSIONS Based on the current evidence, HA may be considered for preventing the development of hyponatremia in liver cirrhosis, especially in those undergoing LVP, and treating hyponatremia. Well-designed studies are required to clarify the effects of HA infusion on hyponatremia in liver cirrhosis.

American journal of translational research. 2021;13(5):5526-5532
Abstract
OBJECTIVE To explore the clinical efficacy of comprehensive rehabilitation nursing (CRN) intervention in patients with cerebral hemorrhagic hemiplegia (CHH). METHODS A total of 102 patients with CHH admitted to our hospital were selected for the prospective study. The patients were randomly divided into the control group (n=51) and the observation group (n=51) according to the random number table method. Routine nursing was performed in the control group, while CRN was conducted in the observation group. Fugl-Meyer motor function assessment scale, activity of daily living scale (Barthel index), self-rating anxiety scale (SAS), complications and muscle strength improvement (Brunnstrom assessment) were compared between the two groups. RESULTS Compared with those before nursing, Fugl-Meyer score, Barthel index and SAS score in the two groups after nursing were significantly improved (P<0.01). Fugl-Meyer score and Barthel index of the observation group were significantly higher than those of the control group after nursing, while SAS score showed the opposite change (P<0.001). The incidence of complications in the control group was 49.02%, and that in the observation group was 29.41% (P<0.05). The rate of muscle strength improvement in the observation group was 80.39% after nursing, which was significantly higher than that in the control group (60.78%; P<0.05). CONCLUSION CRN intervention has a positive clinical efficacy in patients with CHH. It can enhance motor ability, improve the ability of daily life, amend psychological mood and reduce the incidence of complications.

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.
