    甾醇14-脱甲基酶(CYP51)抑制剂,包括新的化学实体和重新利用的药物,已经成为查加斯病治疗的有希望的候选人,基于报告抗克氏锥虫活性的临床前研究。三唑类如雷福康唑(RAV)和泊沙康唑(POS)已进入临床试验。出乎意料的是,它们在慢性查加斯病患者中的疗效是短暂的,并且它们的活性不优于苯并咪唑(BZ)处理。本文旨在通过应用系统评价策略,总结CYP51抑制剂抗克氏虫的全球活性的证据。偏见风险评估,和来自体内研究的荟萃分析。搜索PubMed和Embase数据库中的原始文章,获得符合纳入标准的56篇相关论文。动物模型的特点,寄生虫菌株,治疗方案,并提取治愈率。主要结果,如最大寄生虫血症值,生存,和寄生虫学治愈记录进行荟萃分析,如果可能的话。在大多数研究中,偏倚的风险是不确定的。用伊曲康唑治疗的动物,RAV,或POS存活时间明显长于未治疗组(RR=4.85[3.62,6.49],P<0.00001),它们与用阳性对照药物治疗的动物没有差异(RR=1.01[0.98,1.04],P=0.54)。此外,总体分析表明,与BZ或NFX治疗相比,RAV或POS不太可能达到寄生虫学治愈(OD=0.49[0.31,0.77],P=0.002)。这项系统评价有助于理解为什么唑类药物在临床试验中失败,更重要的是,如何通过填补基础之间的空白来改善T.Cruzi感染的动物模型,翻译,和临床研究。
    Sterol 14-demethylase (CYP51) inhibitors, encompassing new chemical entities and repurposed drugs, have emerged as promising candidates for Chagas disease treatment, based on preclinical studies reporting anti-Trypanosoma cruzi activity. Triazoles like ravuconazole (RAV) and posaconazole (POS) progressed to clinical trials. Unexpectedly, their efficacy was transient in chronic Chagas disease patients, and their activity was not superior to benznidazole (BZ) treatment. This paper aims to summarize evidence on the global activity of CYP51 inhibitors against T. cruzi by applying systematic review strategies, risk of bias assessment, and meta-analysis from in vivo studies. PubMed and Embase databases were searched for original articles, obtaining fifty-six relevant papers meeting inclusion criteria. Characteristics of animal models, parasite strain, treatment schemes, and cure rates were extracted. Primary outcomes such as maximum parasitaemia values, survival, and parasitological cure were recorded for meta-analysis, when possible. The risk of bias was uncertain in most studies. Animals treated with itraconazole, RAV, or POS survived significantly longer than the infected non-treated groups (RR = 4.85 [3.62, 6.49], P < 0.00001), and they showed no differences with animals treated with positive control drugs (RR = 1.01 [0.98, 1.04], P = 0.54). Furthermore, the overall analysis showed that RAV or POS was not likely to achieve parasitological cure when compared with BZ or NFX treatment (OD = 0.49 [0.31, 0.77], P = 0.002). This systematic review contributes to understanding why the azoles had failed in clinical trials and, more importantly, how to improve the animal models of T. cruzi infection by filling the gaps between basic, translational, and clinical research.

    新烟碱,有时缩写为neonics,代表一类与尼古丁化学相似的神经活性杀虫剂。新烟碱是自1980年代后期发现以来全球最广泛使用的杀虫剂。它们的理化性质超过了以前建立的杀虫剂,有助于它们在农业和木材处理等各个领域的受欢迎程度。新烟碱对环境的影响,经常被忽视,强调迫切需要开发工具来检测和理解他们的行为。用于农药检测的常规方法具有局限性。色谱技术灵敏但价格昂贵,产生废物,并且需要复杂的样品制备。生物测定缺乏特异性和准确性,使它们适合与仪器方法一起作为初步测试。基于适体的生物传感器由于其快速响应而被认为是新烟碱检测的有利工具,用户友好的性质,成本效益,以及现场检测的适用性。这篇全面的综述代表了针对吡虫啉等新烟碱类化合物的基于适体的生物传感器的首次深入分析,噻虫嗪,clothianidin,啶虫脒,噻虫啉,尼坦吡喃,还有dinotefuran.此外,该综述提供了对关键挑战的宝贵见解,这些挑战需要迅速关注,以便从研究成功过渡到实际领域应用。
    Neonicotinoids, sometimes abbreviated as neonics, represent a class of neuro-active insecticides with chemical similarities to nicotine. Neonicotinoids are the most widely adopted group of insecticides globally since their discovery in the late 1980s. Their physiochemical properties surpass those of previously established insecticides, contributing to their popularity in various sectors such as agriculture and wood treatment. The environmental impact of neonicotinoids, often overlooked, underscores the urgency to develop tools for their detection and understanding of their behavior. Conventional methods for pesticide detection have limitations. Chromatographic techniques are sensitive but expensive, generate waste, and require complex sample preparation. Bioassays lack specificity and accuracy, making them suitable as preliminary tests in conjunction with instrumental methods. Aptamer-based biosensor is recognized as an advantageous tool for neonicotinoids detection due to its rapid response, user-friendly nature, cost-effectiveness, and suitability for on-site detection. This comprehensive review represents the inaugural in-depth analysis of advancements in aptamer-based biosensors targeting neonicotinoids such as imidacloprid, thiamethoxam, clothianidin, acetamiprid, thiacloprid, nitenpyram, and dinotefuran. Additionally, the review offers valuable insights into the critical challenges requiring prompt attention for the successful transition from research to practical field applications.

    新烟碱类杀虫剂用于广泛的昆虫。越来越多的证据支持这些神经活性杀虫剂被归类为无脊椎动物的毒物。然而,关于它们在脊椎动物和哺乳动物中的毒性的公开数据有限。当前的系统综述集中于几种新烟碱类农药的最新知识及其对啮齿动物和人体生理学的非急性毒性。7种新烟碱类(即吡虫啉,啶虫脒,clothianidin,dinotfuran,噻虫嗪,噻虫啉,和nitenpyra)最初被确定。随后,进行了文献筛选,以收集有关非急性接触这些杀虫剂的信息。根据卫生与翻译办公室(OHAT)框架,纳入了99项研究,并评估了其偏倚风险和证据水平。所有99篇论文都显示了生殖毒性的证据,肝毒性,肾毒性,神经毒性,免疫毒性,和氧化应激诱导,对啮齿动物的健康影响有高水平的证据,对人类健康有中等水平的证据。在99篇论文中研究最多的杀虫剂类型是吡虫啉(55篇论文),其次是啶虫脒(22篇论文),噻虫胺(21篇论文),和噻虫啉(11篇论文)。虽然99篇论文中有10篇评估了噻虫胺之间的关系,噻虫嗪,dinotfuran,和亚硝啶,显示肝损伤的证据,生殖系统中氧化应激标志物的功能障碍,和肠道毒性。本系统综述全面概述了新烟碱类杀虫剂对人类和啮齿动物造成的潜在风险,对健康有显著影响。然而,需要进一步的研究来更好地强调和理解这些杀虫剂的病理生理机制,考虑到可能影响其毒性的各种因素。
    Neonicotinoid pesticides are utilized against an extensive range of insects. A growing body of evidence supports that these neuro-active insecticides are classified as toxicants in invertebrates. However, there is limited published data regarding their toxicity in vertebrates and mammals. the current systematic review is focused on the up-to-date knowledge available for several neonicotinoid pesticides and their non-acute toxicity on rodents and human physiology. Oral lethal dose 50 (LD50) of seven neonicotinoids (i.e. imidacloprid, acetamiprid, clothianidin, dinotefuran, thiamethoxam, thiacloprid, and nitenpyram) was initially identified. Subsequently, a screening of the literature was conducted to collect information about non-acute exposure to these insecticides. 99 studies were included and assessed for their risk of bias and level of evidence according to the Office of Health and Translation (OHAT) framework. All the 99 included papers indicate evidence of reproductive toxicity, hepatotoxicity, nephrotoxicity, neurotoxicity, immunotoxicity, and oxidative stress induction with a high level of evidence in the health effect of rodents and a moderate level of evidence for human health. The most studied type of these insecticides among 99 papers was imidacloprid (55 papers), followed by acetamiprid (22 papers), clothianidin (21 papers), and thiacloprid (11 papers). While 10 of 99 papers assessed the relationship between clothianidin, thiamethoxam, dinotefuran, and nitenpyram, showing evidence of liver injury, dysfunctions of oxidative stress markers in the reproductive system, and intestinal toxicity. This systematic review provides a comprehensive overview of the potential risks caused by neonicotinoid insecticides to humans and rodents with salient health effects. However, further research is needed to better emphasize and understand the patho-physiological mechanisms of these insecticides, taking into account various factors that can influence their toxicity.

    在化妆品产品中频繁使用甲基氯异噻唑啉酮/甲基异噻唑啉酮(MCI/MI)和MI是对这些防腐剂(杀生物剂)广泛致敏和过敏性接触性皮炎的主要原因。它们在非化妆品产品中的使用也是致敏的重要来源。关于致敏率和苯并异噻唑啉酮(BIT)的使用知之甚少,辛基异噻唑啉酮(OIT),和二氯辛基异噻唑啉酮(DCOIT),这在欧洲化妆品中从未被允许。BIT和OIT偶尔会进行常规的补丁测试。这些防腐剂通常一起用于化学产品和制品中。在这项研究中,我们回顾了对MI的接触过敏的发生,BIT,OIT,和DCOIT随着时间的推移,基于大型研究中伴随的补丁测试,和病例报告。我们审查欧盟立法,我们讨论了工业的作用,监管者,以及预防致敏和保护健康的皮肤病学。对MI的接触过敏的频率,BIT,OIT增加了。对DCOIT的接触过敏的频率尚不清楚,因为它很少经过补丁测试。化学产品和物品中异噻唑啉酮的标签信息,无论浓度如何,是评估相关性所必需的,向患者提供信息,避免接触和过敏性接触性皮炎。
    Frequent use of methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) and MI in cosmetic products has been the main cause of widespread sensitization and allergic contact dermatitis to these preservatives (biocides). Their use in non-cosmetic products is also an important source of sensitization. Less is known about sensitization rates and use of benzisothiazolinone (BIT), octylisothiazolinone (OIT), and dichlorooctylisothiazolinone (DCOIT), which have never been permitted in cosmetic products in Europe. BIT and OIT have occasionally been routinely patch-tested. These preservatives are often used together in chemical products and articles. In this study, we review the occurrence of contact allergy to MI, BIT, OIT, and DCOIT over time, based on concomitant patch testing in large studies, and case reports. We review EU legislations, and we discuss the role of industry, regulators, and dermatology in prevention of sensitization and protection of health. The frequency of contact allergy to MI, BIT, and OIT has increased. The frequency of contact allergy to DCOIT is not known because it has seldom been patch-tested. Label information on isothiazolinones in chemical products and articles, irrespective of concentration, is required for assessment of relevance, information to patients, and avoidance of exposure and allergic contact dermatitis.

  • 文章类型: Meta-Analysis
    目的:抗毒蕈药和β3-肾上腺素受体激动剂,Mirabegron,通常用于治疗膀胱过度活动症(OAB)患者,而α1-肾上腺素受体拮抗剂(α1-阻断剂)是用于治疗良性前列腺增生(BPH)继发的下尿路症状(LUTS)的主要药物。由于这些情况通常一起发生,本系统综述的目的是确定在BPH和OAB继发的LUTS患者中比较α1-阻滞剂加米拉贝隆与α1-阻滞剂加抗毒蕈碱的应用的出版物.随后进行荟萃分析以探索这些组合的安全性和有效性。
    方法:包含的记录必须来自平行组,随机临床试验,持续时间≥8周。参与者为男性,继发于BPH和OAB的LUTS。鉴定的间接分析比较了α1-阻断剂加OAB剂与α1-阻断剂加安慰剂。PubMed/医学文献分析和在线检索系统,摘录医学数据库,Cochrane中央受控试验登记册,并在ClinicalTrials.gov注册表中搜索相关记录,直到2020年3月5日。安全性结果包括总体治疗引起的不良事件(TEAE)和尿潴留的发生率,后空隙残余体积,和最大尿流(Qmax)。主要疗效结果是排尿/天,失禁发作/天,和紧急事件/天,次要结果为膀胱过度活动症症状评分和国际前列腺症状评分。采用贝叶斯网络荟萃分析方法进行荟萃分析。
    结果:在确定的1039条记录中,24人符合纳入荟萃分析的条件。就进行的所有安全性和有效性分析所确定的比较而言,α1-阻断剂加米拉贝隆和α1-阻断剂加抗毒蕈碱组之间没有统计学上的显着差异。在安全性参数方面,与α1-阻滞剂加抗毒蕈碱组相比,α1-阻滞剂加米拉贝隆组经常观察到优于数字的结果。包括TEAE,尿潴留,和Qmax。对于一些疗效参数,最值得注意的是排尿/天,α1-受体阻滞剂加抗毒蕈碱组的数值结果优异.纳入的记录中注意到报告和研究变异性的不一致,这阻碍了数据解释。
    结论:这项系统评价和荟萃分析显示,在BPH和OAB继发的男性LUTS患者中,α1受体阻滞剂加米拉贝隆和α1受体阻滞剂加抗毒蕈碱具有相似的安全性和有效性。患者可以,因此,受益于在临床环境中使用这两种组合。
    OBJECTIVE: Antimuscarinics and the β3-adrenoreceptor agonist, mirabegron, are commonly used for treating patients with overactive bladder (OAB) and α1 -adrenoreceptor antagonists (α1 -blockers) are the main pharmacological agents used for treating lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). As these conditions commonly occur together, the aim of this systematic review was to identify publications that compared the use of an α1 -blocker plus mirabegron with an α1 -blocker plus antimuscarinic in men with LUTS secondary to BPH and OAB. A meta-analysis was subsequently conducted to explore the safety and efficacy of these combinations.
    METHODS: Included records had to be from a parallel-group, randomized clinical trial that was ≥8 weeks in duration. Participants were male with LUTS secondary to BPH and OAB. The indirect analyses that were identified compared an α1 -blocker plus OAB agent with an α1 -blocker plus placebo. The PubMed/Medical Literature Analysis and Retrieval System Online, the Excerpta Medica Database, the Cochrane Central Register of Controlled Trials, and the ClinicalTrials.gov registry were searched for relevant records up until March 5, 2020. Safety outcomes included incidences of overall treatment-emergent adverse events (TEAEs) and urinary retention, postvoid residual volume, and maximum urinary flow (Qmax ). Primary efficacy outcomes were micturitions/day, incontinence episodes/day, and urgency episodes/day, and secondary outcomes were Overactive Bladder Symptom Score and International Prostate Symptom Score. A Bayesian network meta-analysis approach was used for the meta-analysis.
    RESULTS: Out of a total of 1039 records identified, 24 were eligible for inclusion in the meta-analysis. There were no statistically significant differences between the α1 -blocker plus mirabegron and α1 -blocker plus antimuscarinic groups in terms of the comparisons identified for all the safety and efficacy analyses conducted. Numerically superior results were frequently observed for the α1 -blocker plus mirabegron group compared with the α1 -blocker plus antimuscarinic group for the safety parameters, including TEAEs, urinary retention, and Qmax . For some of the efficacy parameters, most notably micturitions/day, numerically superior results were noted for the α1 -blocker plus antimuscarinic group. Inconsistency in reporting and study variability were noted in the included records, which hindered data interpretation.
    CONCLUSIONS: This systematic review and meta-analysis showed that an α1 -blocker plus mirabegron and an α1 -blocker plus antimuscarinic have similar safety and efficacy profiles in male patients with LUTS secondary to BPH and OAB. Patients may, therefore, benefit from the use of either combination within the clinical setting.

    背景:Alpelisib是一种PI3K抑制剂,用于氟维司群治疗晚期或转移性激素受体(HR)阳性,人表皮生长因子受体2(HER2)阴性,PIK3CA突变乳腺癌。在第三阶段SOLAR-1试验中,在接受alpelisib-氟维司群的患者中,有36.6%的患者报告了3/4级高血糖事件,而接受安慰剂-氟维司群的患者为0.7%.由于糖尿病酮症酸中毒(DKA)的病例报告与使用alpelisib有关,这项研究的目的是描述FAERS报告的这种严重不良反应的病例.
    方法:使用FAERS数据库,通过计算2019年至2022年使用alpelisib的DKA事件的报告比值比(ROR),进行了回顾性不相称性分析。PubMed文献综述了以alpelisib诱导的DKA为特征的病例报告。
    结果:药物警戒数据库分析显示,在87例使用alpelisib的DKA病例中,报告有意义(ROR9.84,95%置信区间7.3-13.2),包括住院和死亡报告的结果。对11例已发表的病例报告的回顾显示,DKA的中位发作时间为14天,并有可能成功进行再激发。
    结论:DKA和alpelisib暴露与报告存在显著关联。与SOLAR-1中报道的相比,我们在我们的分析中观察到高血糖发作的中位时间相似。考虑到这种毒性的早期发作,启动alpelisib时,必须密切监测患者。在先前服用抗高血糖药物的那些药物中加入先发制人的抗高血糖或逐步升级有利于降低alpelisib的高血糖的严重程度。需要进一步研究风险因素,以更好地阐明哪些患者需要先发制人的治疗。
    BACKGROUND: Alpelisib is a PI3K inhibitor indicated with fulvestrant for treatment of advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, PIK3CA-mutated breast cancer. In the phase III SOLAR-1 trial, grade 3/4 hyperglycemic events were reported in 36.6% of patients receiving alpelisib-fulvestrant compared to 0.7% receiving placebo-fulvestrant. As case reports of diabetic ketoacidosis (DKA) have been associated with alpelisib use, the goal of this study was to characterize the FAERS reported cases of this severe adverse effect.
    METHODS: A retrospective disproportionality analysis was performed using the FAERS database by calculating the reporting odds ratio (ROR) of DKA events with alpelisib from 2019 to 2022. A PubMed literature review of case reports characterizing alpelisib-induced DKA was performed.
    RESULTS: Pharmacovigilance database analysis revealed significance in reporting among 87 DKA cases with alpelisib (ROR 9.84, 95% confidence interval 7.3-13.2), including hospitalization and death as reported outcomes. Review of 11 published case reports reveals median onset of DKA at 14 days with successful rechallenge possible.
    CONCLUSIONS: Significant association with reporting exists between DKA and alpelisib exposure. We observed similar median time to onset of hyperglycemia between our analysis compared to that reported in SOLAR-1. Considering early onset of this toxicity, it is imperative that patients be closely monitored when initiating alpelisib. Addition of a preemptive antihyperglycemic or escalation in those previously on antihyperglycemic medications is beneficial in decreasing the severity of hyperglycemia with alpelisib. Further study investigating risk factors is warranted to better elucidate which patients require preemptive therapy.

    背景:棕色脂肪组织(BAT)由于其产热和抗肥胖特性,已成为代谢紊乱的潜在治疗靶标。β3-肾上腺素能受体(β3-AR)激动剂作为BAT激活和代谢调节的潜在药物也受到关注。Mirabegron,临床上用于膀胱过度活动症的选择性β3-AR激动剂,已被探索其在代谢紊乱中的效用。然而,围绕Mirabegron激活BAT以加速新陈代谢的能力的争议需要进一步研究。本系统综述的目的是全面描述米拉贝隆对人类BAT及其代谢的影响。
    方法:我们搜索了PubMedCentral,WebofScience,Embase,和CochraneLibrary数据库,用于从数据库建立之日起至2023年3月发表的相关论文,以进行系统评价和荟萃分析。我们提取了主要结果指标的数据,如BAT量,BAT活动,体温,和静息能量消耗(REE),以及次要结果指标,如心率(HR),舒张压(DBP),收缩压(SBP),非酯化脂肪酸(NEFA),血糖,和相关研究的血液胰岛素。对于没有为荟萃分析提供合适数据的研究,我们使用了叙事数据合成。对于为荟萃分析提供合适数据的研究,我们使用RevMan5.4软件进行了荟萃分析。
    结果:我们回顾了10篇论文,其中6篇纳入了我们的荟萃分析。我们的发现表明,与安慰剂或给药前人群相比,米拉贝隆的BAT体积(p=0.72)或血糖(p=0.52)没有显着变化。然而,患者BAT活性显着增加(p<0.01),血液NEFA(p<0.01),体温(p<0.01),稀土元素(p<0.01),HR(p<0.01),DBP(p<0.01),SBP(p=0.25),血胰岛素(p<0.01)。
    结论:通过我们对6篇论文的荟萃分析,我们发现米拉贝隆有可能增加人类的BAT活动,REE,NEFA内容,体温,HR,血压,和血液胰岛素含量。这些作用可能导致肥胖/超重和糖尿病患者的血糖水平降低。此外,米拉贝隆激活BAT可以代表一种治疗肥胖的新方法,糖尿病,和心血管疾病。
    CRD42023413446,2023年4月11日。
    BACKGROUND: Brown adipose tissue (BAT) has emerged as a potential therapeutic target for metabolic disorders due to its thermogenic and anti-obesity properties. β3-adrenergic receptor (β3-AR) agonists have also gained attention as potential agents for BAT activation and metabolic regulation. Mirabegron, a selective β3-AR-agonist used clinically for overactive bladder syndrome, has been explored for its utility in metabolic disorders. However, the controversy surrounding the ability of mirabegron to activate BAT to accelerate metabolism requires further investigation. The aim of this systematic review is to characterize comprehensively the impact of mirabegron on human BAT and its metabolism.
    METHODS: We searched PubMed Central, Web of Science, Embase, and Cochrane Library databases for relevant papers published from the date of database inception to March 2023 for systematic reviews and meta-analyses. We extracted data on primary outcome indicators such as BAT volume, BAT activity, body temperature, and resting energy expenditure (REE), as well as secondary outcome indicators such as heart rate (HR), diastolic blood pressure (DBP), systolic blood pressure (SBP), non-esterified fatty acids (NEFA), blood glucose, and blood insulin from relevant studies. For studies that did not provide suitable data for meta-analysis, we used narrative data synthesis. For studies that provided suitable data for meta-analysis, we conducted meta-analysis using RevMan 5.4 software.
    RESULTS: We reviewed 10 papers and included 6 in our meta-analysis. Our findings revealed no significant changes in BAT volume (p = 0.72) or blood glucose (p = 0.52) with mirabegron when compared to the placebo or pre-dose population. However, patients showed significant increases in BAT activity (p < 0.01), blood NEFA (p < 0.01), body temperature (p < 0.01), REE (p < 0.01), HR (p < 0.01), DBP (p < 0.01), SBP (p = 0.25), and blood insulin (p < 0.01).
    CONCLUSIONS: Through our meta-analysis of 6 papers, we found that mirabegron has the potential to increase human BAT activity, REE, NEFA content, body temperature, HR, blood pressure, and blood insulin content. These effects may lead to reductions in blood glucose levels in obese/overweight and diabetic patients. Additionally, the activation of BAT by mirabegron could represent a novel approach for treating obesity, diabetes, and cardiovascular disease.

    目的:马赛替尼,最初开发的酪氨酸激酶抑制剂用于癌症治疗,通过调节与神经变性有关的关键途径,在各种神经系统疾病中显示出潜在的神经保护作用。本范围综述旨在总结马赛替尼从临床前到临床研究的神经保护活性的现有证据。
    方法:本范围审查是按照Arksey和O'Malley描述的指南以及系统审查和荟萃分析指南的首选报告项目进行的。纳入标准涵盖了所有报告马赛替尼神经保护作用的原始研究,包括临床研究,动物研究,和体外研究。
    结果:共有16项研究符合纳入标准,纳入本综述。这些包括五项随机对照试验(RCT),一项事后分析研究,一例病例报告,和九项动物研究。RCT专注于阿尔茨海默病(两项研究),多发性硬化症(两项研究),和肌萎缩侧索硬化症(一项研究)。在所有纳入的研究中,马赛替尼始终表现出神经保护特性。然而,大多数RCT报告了对马赛替尼安全性的担忧.临床前研究揭示了马赛替尼的神经保护机制,其中包括抑制某些激酶干扰细胞增殖和存活,减少神经炎症,和展示抗氧化活性。
    结论:目前的证据表明,马赛替尼在神经退行性疾病中具有良好的治疗效果。然而,需要进一步的研究来验证和扩展这些发现,特别是关于马赛替尼发挥其治疗作用的确切机制。未来的研究还应集中在解决与马赛替尼使用相关的安全性问题上。
    OBJECTIVE: Masitinib, originally developed as a tyrosine kinase inhibitor for cancer treatment, has shown potential neuroprotective effects in various neurological disorders by modulating key pathways implicated in neurodegeneration. This scoping review aimed to summarize the current evidence of masitinib\'s neuroprotective activities from preclinical to clinical studies.
    METHODS: This scoping review was conducted following the guidelines described by Arksey and O\'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The inclusion criteria covered all original studies reporting on the neuroprotective effects of masitinib, including clinical studies, animal studies, and in vitro studies.
    RESULTS: A total of 16 studies met the inclusion criteria and were included in the review. These comprised five randomized controlled trials (RCTs), one post-hoc analysis study, one case report, and nine animal studies. The RCTs focused on Alzheimer\'s disease (two studies), multiple sclerosis (two studies), and amyotrophic lateral sclerosis (one study). Across all included studies, masitinib consistently demonstrated neuroprotective properties. However, the majority of RCTs reported concerns regarding the safety profile of masitinib. Preclinical studies revealed the neuroprotective mechanisms of masitinib, which include inhibition of certain kinases interfering with cell proliferation and survival, reduction of neuroinflammation, and exhibition of antioxidant activity.
    CONCLUSIONS: The current evidence suggests a promising therapeutic benefit of masitinib in neurodegenerative diseases. However, further research is necessary to validate and expand upon these findings, particularly regarding the precise mechanisms through which masitinib exerts its therapeutic effects. Future studies should also focus on addressing the safety concerns associated with masitinib use.

    平衡房颤(AF)患者的中风预防和出血风险是具有挑战性的。目前,直接口服抗凝剂(DOAC)被认为是国际指南中治疗AF患者的标准护理。我们的目的是评估老年人房颤长期摄入DOAC的安全性。我们纳入了老年(≥65岁)房颤患者的RCTs。2022年4月19日在MEDLINE和EMBASE中进行了系统搜索。为了确定偏见的风险,应用了RoB2工具。我们使用随机效应荟萃分析汇总结果。使用GRADE评估证据质量。确定了11个RCT,共有63,374名患者。两个随机对照试验比较了阿哌沙班与华法林或阿司匹林,四个依度沙班与安慰剂,阿司匹林,或维生素K拮抗剂(VKAs),两个达比加特兰和三个利伐沙班和华法林。DOAC可能降低老年房颤患者的死亡率(HR0.8995CI0.77至1.02)。与VKAs相比,低剂量DOAC可能减少出血(HR范围为0.47至1.01)。对于高剂量DOACS,出血风险差异很大(HR范围为0.80至1.40)。我们发现低剂量DOAC可能降低房颤患者的死亡率。此外,与VKAs相比,阿哌沙班和依度沙班可能与较少的主要或临床相关出血(MCRB)事件相关.对于达比加群和利伐沙班来说,MCRB的风险因剂量而异。此外,亚组分析显示,在高龄患者(≥85岁)中,使用DOAC时,MCRB事件的风险可能会增加.注册:PROSPERO:CRD42020187876。
    Balancing stroke prevention and risk of bleeding in patients with atrial fibrillation (AF) is challenging. Direct oral anticoagulants (DOACs) are by now considered standard of care for treating patients with AF in international guidelines. Our objective was to assess the safety of long-term intake of DOACs in older adults with AF. We included RCTs in elderly (≥ 65 years) patients with AF. A systematic search in MEDLINE and EMBASE was performed on 19 April 2022. For determination of risk of bias, the RoB 2 tool was applied. We pooled outcomes using random-effects meta-analyses. The quality of evidence was assessed using GRADE. Eleven RCTs with a total of 63,374 patients were identified. Two RCTs compared apixaban with either warfarin or aspirin, four edoxaban with either placebo, aspirin, or vitamin K antagonists (VKAs), two dabigatran with warfarin and three rivaroxaban with warfarin. DOACs probably reduce mortality in elderly patients with AF (HR 0.89 95%CI 0.77 to 1.02). Low-dose DOACs likely reduce bleeding compared to VKAs (HR ranged from 0.47 to 1.01). For high-dose DOACS the risk of bleeding varied widely (HR ranged from 0.80 to 1.40). We found that low-dose DOACs probably decrease mortality in AF patients. Moreover, apixaban and probably edoxaban are associated with fewer major or clinically relevant bleeding (MCRB) events compared to VKAs. For dabigatran and rivaroxaban, the risk of MCRB varies depending on dose. Moreover, subgroup analyses indicate that in the very old (≥ 85) the risk for MCRB events might be increased when using DOACs.Registration: PROSPERO: CRD42020187876.

    背景:癌症是一种以细胞异常繁殖为特征的疾病,是世界上第二大死亡原因。由于选择性低等因素,寻找新的有效和安全的抗癌化合物正在进行中,高毒性,和多重耐药性。因此,源自Isatin的杂环化合物,已经在体内和临床试验中测试了已经获得有希望的体外抗癌活性的噻唑和邻苯二甲酰亚胺。
    目的:这篇综述集中于噻唑,Isatin,和邻苯二甲酰亚胺衍生物,在2015年至2022年间的文献中报道,具有体内抗癌活性和临床试验。
    方法:在PUBMED中进行了书目检索,MEDLINE,Elsevier,和CAPES周期性数据库,为最近6年具有体内抗肿瘤活性的每个药效组选择相关作品。
    结果:在我们的研究中,选择了68篇符合该范围的文章,并进行了批判性分析。这些文章是考虑到抗肿瘤活性的类型及其发表年份而组织的。本文报道的一些化合物对几种肿瘤类型表现出有效的抗肿瘤活性。
    结论:这篇综述使我们能够突出报道有希望的结构用于治疗各种癌症类型的作品,并证明了特级结构噻唑,在具有抗肿瘤活性的化合物的新合成设计和分子优化中,拉丁和邻苯二甲酰亚胺是重要的。
    BACKGROUND: Cancer is a disease characterized by the abnormal multiplication of cells and is the second leading cause of death in the world. The search for new effective and safe anticancer compounds is ongoing due to factors such as low selectivity, high toxicity, and multidrug resistance. Thus, heterocyclic compounds derived from isatin, thiazole and phthalimide that have achieved promising in vitro anticancer activity have been tested in vivo and in clinical trials.
    OBJECTIVE: This review focused on the compilation of promising data from thiazole, isatin, and phthalimide derivatives, reported in the literature between 2015 and 2022, with in vivo anticancer activity and clinical trials.
    METHODS: A bibliographic search was carried out in the PUBMED, MEDLINE, ELSEVIER, and CAPES PERIODIC databases, selecting relevant works for each pharmacophoric group with in vivo antitumor activity in the last 6 years.
    RESULTS: In our study, 68 articles that fit the scope were selected and critically analyzed. These articles were organized considering the type of antitumor activity and their year of publication. Some compounds reported here demonstrated potent antitumor activity against several tumor types.
    CONCLUSIONS: This review allowed us to highlight works that reported promising structures for the treatment of various cancer types and also demonstrated that the privileged structures thiazole, isatin and phthalimide are important in the design of new syntheses and molecular optimization of compounds with antitumor activity.
