Evaluation of efficacy and safety of esmolol in treating patients with septic shock: A protocol for systematic review and meta-analysis

Background:In septic shock cases, tachycardia and a hyperdynamic hemodynamic profile are characteristics of the condition. It has been reported that using beta antagonist esmolol constitutes a form of treatment to reduce heart rate to improve diastolic filling time and elevate cardiac output, which reduces vasopressor support. Still, there are controversial results. Therefore, in this study, the primary objective is to perform a meta-analysis by systematically evaluating the efficiency and security of using esmolol to treat septic shocks.Methods:A systematic literature search for relevant randomized controlled trials that report evaluations on the efficiency and safety of using esmolol to treat septic shock patients from their inception to February 2022 will be conducted in three databases containing publications in Chinese language (WanFang, Chinese BioMedical Literature Database, and China National Knowledge Infrastructure) and four databases containing English language publications (Cochrane Library, PubMed, Web of Science, and EMBASE). The screening of the relevant studies will be performed by a pair of authors independently, and the screening involves examining the title, abstract and full-text stages, data extraction, and bias risk assessment. The results are summarized through the fixed-effects and random-effects models, the respective models will be utilized for data pooling according to the heterogeneity of studies that will be included. Moreover, publication bias is assessed if more than ten studies are considered.Results:The results are a high-quality synthesis of the most recent evidence for esmolol usage in septic shock treatment.Conclusion:Up-to-date evidence will be provided through the results of this systematic review related to assessing the efficacy and safeness of esmolol usage in treating septic shock.Ethics and dissemination:Ethical permissions are not required as prepublished data are used.OSF registration number:DOI 10.17605/OSF.IO/SKEZ7     

Combined prognostic value of preoperative serum thyrotrophin and thyroid hormone concentration in papillary thyroid cancer

BackgroundA growing number of studies have found a close association between thyroid hormones and thyrotrophin (TSH), and they also have prognostic significance in some cancer types; this study aimed to investigate the prognostic value of free triiodothyronine (fT3), free thyroxine (fT4), fT3/fT4, TSH, and their combination in patients with papillary thyroid carcinoma (PTC).MethodsThis study retrospectively analyzed the relevant data of 726 newly diagnosed PTC patients. Both univariate and multivariate analyses were used to predict the recurrence rate, and a risk score was established. In addition, with the use of a random survival forest, a random forest (RF) score was constructed. After calculating the area under the curve (AUC), the diagnostic efficacy of risk score, RF score, and four indicators was compared.ResultsfT3, fT4, fT3/fT4, and TSH were strongly associated with some invasive clinicopathological features and postoperative recurrence. Patients with high expression of fT4 and TSH have a high risk of recurrence. By contrast, patients with high expression of fT3 and fT3/fT4 have a low risk of recurrence. At the same time, the combined use of various indicators is more helpful for establishing an accurate diagnosis. By comparison, we found that the RF score was better than the risk score in terms of predicting the recurrence of PTC.ConclusionThe diagnostic accuracy of a combination of fT3, fT4, fT3/fT4, and TSH can help improve our clinical estimate of the risk of recurrent PTC, thus allowing the development of a more effective treatment plan for patients.

Aligned acupuncture at muscle regions plus cutaneous needle for upper limb spasticity after stroke: A multicenter randomized controlled trial

Objective： To evaluate the clinical efficacy of aligned acupuncture at the muscle regions plus cutaneous needle for post-stroke upper limb spasticity. Methods： By adopting a design of multicenter randomized controlled clinical trial, 488 patients with post-stroke upper limb spasticity were randomized into a treatment group and a control group, 244 in each group. In addition to rehabilitation training, the treatment group received aligned acupuncture at the muscle regions plus cutaneous needle therapy and the control group received conventional Western medicine. After successive 3-week treatments, the clinical efficacy, spasticity degree of the upper limb, joint function, and neurological defect degree were evaluated in the two groups. Results： The total effective rate was 93.4% in the treatment group versus 61.5% in the control group, and the difference was statistically significant （P 〈 0.05）. The upper-limb spasticity degree, joint function, and neurological defect degree were improved significantly in both groups after intervention （P〈0.05）, and the improvements in the treatment group were more significant than those in the control group （P〈0.05 or P〈0.01）. Conclusion： Aligned acupuncture at the muscle regions plus cutaneous needle therapy is effective in treating post-stroke upper limb spasticity.     

白细胞介素6和hepcidin在弥漫大B细胞淋巴瘤中的表达及其与贫血的相关性

目的：研究白细胞介素6（IL-6）和hepcidin在弥漫大B细胞淋巴瘤（DLBCL）患者中的表达及其在贫血发生中的作用。方法收集诊断时伴或不伴贫血的45例DLBCL患者,在诊断时抽取外周血标本,分别检测IL-6、hepcidin、血清铁蛋白和血红蛋白（Hb）浓度等。以24名健康志愿者作为对照。结果DLBCL患者的血浆hepcidin及IL-6水平分别为（347±171）μg／L、0.27 ng／L（0～9.61 ng／L）,与健康对照者的（175±92）μg／L、0相比,差异均有统计学意义（均P＜0.001）。在高乳酸脱氢酶（LDH）（P＝0.003）、有B症状（P＝0.040）和年龄校正的国际预后指数（IPI）评分＞1（P＝0.010）的患者中血浆hepcidin水平升高,差异均有统计学意义。在男性（P＝0.003）、肿瘤分期Ⅲ～Ⅳ期（P＝0.008）和IPI评分＞1（P＝0.004）的DLBCL患者中IL-6水平升高,差异均有统计学意义。 hepcidin水平与血清铁蛋白高度相关（r＝0.77,P＜0.001）,与IL-6弱相关（r＝0.31,P＝0.030）,与Hb无相关性（r＝-0.12,P＝0.300）。IL-6表达水平与Hb呈负相关（r＝-0.35,P＝0.009）。多因素分析提示,IL-6可以预测贫血（P＝0.03）,而hepcidin不能预测贫血（P＝0.89）。结论 DLBCL患者血浆hepcidin常高表达,但IL-6水平升高在DLBCL患者贫血的发生中起主要作用。

Über die Abhängigkeit der Reizwirkung eines Herznerven von der tonischen Erregung der übrigen Herznerven

Zusammenfassung Nach Durchschneidung eines Vagosympathicus sinkt die Schwelle für die vom peripheren Stumpfe des anderen Vagosympathicus ausgelöste Herzhemmung.Bei Kröten, bei denen die Reizung des peripheren Vagosympathicusstumpfes eine Acceleration des Herzschlags bewirkte, sank nach Durchschneidung des kontralateralen Vagosympathicus in analoger Weise die Schwelle für die Acceleranswirkung.Das Absinken der Schwelle für die Vaguswirkung nach Durchtrennung des kontralateralen Vagosympathieus beruht auf einer Steigerung der Empfindlichkeit des Herzens für den Vagusstoff. Dies beweisen Versuche, in denen die Acetylcholinempfindlichkeit des bei erhaltener Innervation präparierten Froschherzens an der Straubschen Kanüle vor und nach Entnervung des Herzens geprüft wurde. Nach Durchschneidung beider Vagosympathici wirkt die Füllung des Herzens mit einer Acetylcholinlösung von bestimmter Konzentration wesentlich stärker negativ inotrop als am normal innervierten Herzen. Dagegen ändert sich die Erregbarkeit eines peripheren Vagusstumpfes (gemessen an seiner Chronaxie) nach Durchschneidung des kontralateralen Vagosympathieus nicht.Die isolierte Durchschneidung der Sympathici steigert die Acetylcholinwirkung ebenso wie die Durchschneidung der Vagosympathici. Im wesentlichen beruht also die Steigerung vagaler Reizwirkungen nach Entnervung des Herzens auf dem Wegfall des Acceleranstonus.Durchschneidungsversuche an verschiedenen Stellen des Zentralnervensystems zeigten, daß der Acceleranstonus von spinalen Zentren unterhalten wird.Isolierte Durchschneidungen des Vagus (intracraniell oder peripher nach vorangegangener Sympathicotomie) änderten die Acetylchohnempfindlichkeit des Herzens meist nicht, aber in einzelnen Fällen trat auch bei diesen Versuchen eine leichte Verstärkung der Acetylcholinwirkung auf, ein Effekt, der an ähnliche Beobachtungen vonHofmeister undTschermak an Kröten und Hunden erinnert.

The Relationship between Fat Mass Percentage and Glucose Metabolism in Children and Adolescents: A Systematic Review and Meta-Analysis

To assess the relationship between fat mass percentage (FMP) and glucose metabolism in children aged 0–18 years we performed a systematic review of the literature on Medline/PubMed, SinoMed, Embase and Cochrane Library using the PRISMA 2020 guidelines up to 12 October 2021 for observational studies that assessed the relationship of FMP and glucose metabolism. Twenty studies with 18,576 individuals were included in the meta-analysis. The results showed that FMP was significantly associated with fasting plasma glucose (FPG) (r = 0.08, 95% confidence interval (CI): 0.04–0.13, p < 0.001), fasting plasma insulin (INS) (r = 0.48, 95% CI: 0.37–0.57, p < 0.001), and homeostasis model assessment (HOMA)- insulin resistance (IR) (r = 0.44, 95% CI: 0.33–0.53, p < 0.001). The subgroup analysis according to country or overweight and obesity indicated that these associations remained significant between FMP and INS or HOMA-IR. Our results demonstrated that there is a positive relationship between FMP and FPG. Moreover, subgroup analysis according to country or overweight and obesity indicated that FMP is significantly associated with INS and HOMA-IR. This is the first known systematic review and meta-analysis to determine the associations of FMP with glucose metabolism in children and adolescents.
