    目的:有效的团队合作对于医疗保健中的患者安全至关重要。TeamSTEPPS团队合作感知问卷(T-TPQ)是评估团队合作感知的广泛使用的工具。T-TPQ已在多个国家/地区进行了改编和验证,可用于医院环境。这项研究旨在将T-TPQ翻译成法语并验证其在突尼斯医疗保健专业人员中使用。加强团队合作评估和患者安全举措。
    方法:严格的过程确保了T-TPQ的文化和语言适应,包括回译,专家小组审查,和试点测试。来自凯鲁万四家医院的459名医疗保健专业人员,突尼斯参加了会议。验证性因子分析(CFA)将原始的五因素结构与基于探索性因子分析(EFA)的修订结构进行了比较。
    结果:两种CFA模型都表现出良好的拟合,两者无显著差异(Δχ2=22.51,p=0.79)。由于其既定的理论基础,保留了原有的五因素结构。法国T-TPQ表现出强的内部一致性(α=0.9)。双向随机ICC显示所有五个维度(0.633-0.848)的测试-重测可靠性良好。
    结论:应该承认一些局限性。使用问卷作为数据收集工具是报告偏见的来源,因为害怕被识别或出于“社会可取性”的原因。然而,这种社会愿望是微乎其微的,作为贝克等人。(2010)在仪器的开发过程中采取了缓解这种情况的措施。此外,为了评估态度和看法,自我报告的措施被认为更有效,而行为评估提倡客观措施。此外,参与者被告知没有好的或坏的答案,尽可能仔细回答的重要性,和保密性。此外,考虑到数据收集期,COVID-19大流行及其对招聘的潜在影响,数据收集,参与者的反应。尽管459的样本量符合进行验证性因子分析的推荐标准,正如Bentler和Chou(1987)和(Floyd和Widaman,1995),COVID-19大流行给招聘带来了挑战。增加的工作量和医疗保健专业人员的压力,加上医院和护理单位内的人员调动和研究限制,可能会阻碍实现更大的样本量。这些情况还需要调整数据收集方法,以确保安全和遵守大流行协议。这涉及将在线调查选项与纸质问卷相结合,并在个人数据收集过程中实施更严格的卫生措施。此外,大流行影响了团队合作的看法,因为显著地重新定义了医疗环境,由于患者数量激增,给专业人士带来巨大压力,人员短缺,以及照顾危重病人的情感负担。这种增加的压力和工作量可能会影响团队合作动态,可能促进两种积极的适应,例如增加凝聚力和支持,以及沟通中断和士气下降等负面后果(Terregino等人。,2023年)。
    结论:我们概述了对医疗保健领导者改善团队合作和患者安全的重要实际意义。或者,通过将经过验证的法国T-TPQ纳入其改进策略,医疗保健领导者可以显着增强团队合作和患者安全。这一可靠的工具能够评估工作人员对团队合作优势和劣势的看法,特别是在沟通和领导等领域。通过确定这些关键领域,领导者可以实施有针对性的培训计划和干预措施。事实上,现有的研究机构一致证明了团队培训干预措施的积极影响,团队合作过程和患者结果。这些干预措施已被证明可以提高团队合作技能(Baker等人。,2010年;托马斯和加拉,2013;Weaver等人。,2014).在通信等领域,领导力,形势监测,相互支持,导致死亡率和发病率下降(Weaver等人。,2014).实施团队培训计划促进围绕共同目标的信任和协作,为患者和专业人士提供更有效和更安全的医疗环境。此外,适应文化的T-TPQ不仅有利于个人医疗机构,而且还为全球范围内更广泛的研究和合作提供了机会。通过实现跨文化比较和基准,T-TPQ可以加深我们对团队合作动态如何在不同的医疗保健环境和文化背景下变化的理解。这些知识对于针对特定人群和环境定制团队合作干预和培训计划非常宝贵。确保其有效性和文化相关性。此外,将团队合作培训整合到持续的专业发展中,跨专业和医学教育计划对于培养协作能力和建立高性能的医疗团队至关重要。研究表明,跨专业团队合作经验显着增强护理和医学生的协作能力,强调在医疗保健教育早期纳入团队合作培训的重要性。这种方法为未来的医疗保健专业人员提供了驾驭复杂团队环境的必要技能,最终提高患者护理质量,减轻导致倦怠的工作量问题(Simin等人。,2010年;塞兰,2017年;福克斯等人。,2018)。
    结论:与英语版本相比,T-TPQ的法语版本在语义上是等效的,在文化上具有足够的重测可靠性,扩大其适用性,并有助于理解这种背景下的团队合作观念。法国T-TPQ为评估团队合作提供了宝贵的工具,确定需要改进的地方,并实施干预措施,以加强突尼斯和其他可能的法语地区的团队合作和患者安全。
    OBJECTIVE: Effective teamwork is crucial for patient safety in healthcare. The TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) is a widely used tool for assessing teamwork perceptions. The T-TPQ has been adapted and validated for hospital setting use in several countries. This study aimed to translate and validate the T-TPQ into French for use among Tunisian healthcare professionals, enhancing teamwork assessment and patient safety initiatives.
    METHODS: A rigorous process ensured cultural and linguistic adaptation of the T-TPQ, including back-translation, expert panel review, and pilot testing. 459 healthcare professionals from four hospitals in Kairouan, Tunisia participated. Confirmatory factor analysis (CFA) compared the original five-factor structure with a revised structure based on exploratory factor analysis (EFA).
    RESULTS: Both CFA models demonstrated good fit, with no significant difference between them (∆χ2 = 22.51, p = 0.79). The original five-factor structure was retained due to its established theoretical foundation. The French T-TPQ exhibited strong internal consistency (α = 0.9). Two-way Random ICCs indicated fair to good test-retest reliability for all the five dimensions (0.633-0.848).
    CONCLUSIONS: Several limitations should be acknowledged. The use of a questionnaire as a data collection tool is the source of a reporting bias, for fear of being identified or for reasons of \"social desirability\". Nevertheless, this social desirability was minimal, as Baker et al. (2010) took steps to mitigate this during the instrument\'s development. Additionally, for assessing attitudes and perceptions, self-reported measures are deemed more effective, whereas objective measures are advocated for behavioral assessments. Furthermore, the participants were informed of the absence of good or bad answers, the importance of answering as closely as possible, and the confidentiality. Moreover, considering the data collection period, the COVID- 19 pandemic and its potential impact on recruitment, data collection, and participant responses. Although the sample size of 459 met the recommended criteria for conducting confirmatory factor analysis, as suggested by Bentler and Chou (1987) and (Floyd and Widaman, 1995), the COVID-19 pandemic presented challenges in recruitment. The increased workload and stress on healthcare professionals, coupled with staff redeployment and research restrictions within hospitals and care units, likely hindered achieving an even larger sample size. These circumstances also necessitated adjustments to data collection methods to ensure safety and adherence to pandemic protocols. This involved incorporating online surveys option with paper-based questionnaires and implementing stricter hygiene measures during in person data collection. Furthermore, the pandemic impacted the teamwork perceptions as significantly redefined the healthcare environment, placing immense pressure on professionals due to surging patient volumes, staff shortages, and the emotional burden of caring for critically ill individuals. This heightened stress and workload likely influenced teamwork dynamics, potentially fostering both positive adaptations, such as increased cohesion and support, as well as negative consequences like communication breakdowns and decreased morale (Terregino et al., 2023).
    CONCLUSIONS: We outline significant practical implications for leaders in health care for improving teamwork and patient safety. Or, healthcare leaders can significantly enhance teamwork and patient safety by incorporating the validated French T-TPQ into their improvement strategies. This reliable tool enables the assessment of staff perceptions regarding teamwork strengths and weaknesses, specifically in areas like communication and leadership. By identifying these crucial areas, leaders can implement targeted training programs and interventions. In fact, the existing body of research consistently demonstrates the positive impact of team training interventions, on both teamwork processes and patient outcomes. These interventions have been shown to enhance teamwork skills (Baker et al., 2010; Thomas and Galla, 2013; Weaver et al., 2014). In areas such as communication, leadership, situation monitoring, and mutual support, leading to decreased mortality and morbidity rates (Weaver et al., 2014). Implementing team training programs fosters trust and collaboration around shared goals, contributing to a more effective and safer healthcare environment for both patients and professionals. Additionally, the culturally adapted T-TPQ not only benefits individual healthcare settings but also unlocks opportunities for broader research and collaboration on a global scale. By enabling cross-cultural comparisons and benchmarking, the T-TPQ can deepen our understanding of how teamwork dynamics vary across diverse healthcare environments and cultural contexts. This knowledge is invaluable for tailoring teamwork interventions and training programs to specific populations and settings, ensuring their effectiveness and cultural relevance. Moreover, integrating teamwork training into continuing professional development, interprofessional and medical education initiatives is crucial for cultivating collaborative competencies and building high-performing healthcare teams. Research has shown that interprofessional teamwork experiences significantly enhance collaborative competencies among nursing and medical students, emphasizing the importance of incorporating teamwork training early in healthcare education. This approach equips future healthcare professionals with the necessary skills to navigate complex team environments, ultimately improving patient care quality and mitigating workload issues that contribute to burnout (Simin et al., 2010; Ceylan, 2017; Fox et al., 2018).
    CONCLUSIONS: The French version of the T-TPQ was semantically equivalent and culturally relevant with adequate test-retest reliability as compared to the English version, expanding its applicability and contributing to understanding teamwork perceptions in this context. The French T-TPQ offers a valuable tool for assessing teamwork, identifying areas for improvement, and implementing interventions to enhance teamwork and patient safety in Tunisia and potentially other French-speaking regions.

    氟西汀,作为选择性5-羟色胺摄取抑制剂,已广泛用于调节中枢神经系统中5-羟色胺的神经传递。氟西汀执行许多关键的中枢神经系统相关任务,包括针对小胶质神经毒性的神经保护作用和保护各种与压力相关的不利健康疾病中由压力产生的氧化细胞损伤。研究表明,该药物(氟西汀)除了具有其他基本益处外,还具有镇痛和抗炎特性。此外,现有的治疗方法(NSAIDs,DMARDs,RA的皮质类固醇和其他免疫抑制剂)对慢性免疫模型的作用有限。这些事实为开展氟西汀研究以探索其在称为弗氏完全佐剂(FCA)诱导的关节炎的慢性炎症大鼠模型中的治疗作用奠定了基础。氟西汀在FCA诱导的关节炎大鼠中的治疗效果通过爪体积来评估,爪子直径,关节炎指数和体重在特定天通过28天的实验。这些发现通过血液学进一步共同调查,实验结束时的生化参数和射线照相成像。此外,对基因表达的调节作用(NF-κB,PGE2,COX2,INF-γ,IL-4和IL-10)和抗氧化特性使用qRT-PCR和ELISA试剂盒进行研磨,分别,实验性关节炎大鼠。氟西汀在10,20和40mg/kg剂量下降低(p<0.001)C反应蛋白和类风湿因子的血清浓度,并抑制PGE2,NF-kB的表达,当与关节炎对照比较时,COX2和INF-γ。此外,氟西汀(高剂量)引起IL-4和IL-10的显着升高。这些发现支持氟西汀在慢性炎症模型中的抗炎和抗氧化潜力,并将其用于临床试验。
    Fluoxetine, being a selective serotonin uptake inhibitor, has been broadly used to modulate the neurotransmission of serotonin in the central nervous system. Fluoxetine performs a number of crucial central nervous system-related tasks, including neuroprotective effects against microglial neurotoxicity and protecting oxidative cell damage produced by stress in a variety of stress-related unfavourable health disorders. Studies have shown that the drug (fluoxetine) also has analgesic and anti-inflammatory characteristics in addition to its other basic benefits. Furthermore, existing treatment approaches (NSAIDs, DMARDs, corticosteroids and other immunosuppressants) for RA have limited effects on chronic immunological models. These facts served as the basis for carrying out a study on fluoxetine to explore its therapeutics in a chronic inflammatory rat model called Freund\'s complete adjuvant (FCA)-induced arthritis. The therapeutic effect of the fluoxetine in FCA-induced arthritic rats was assessed by paw volume, paw diameter, arthritic index and body weight at specific days through the experiment of 28 days. These findings were further co-investigated by haematological, biochemical parameters and radiographic imaging at the end of experiment. Furthermore, the modulatory effects on gene expression (NF-κB, PGE2, COX2, INF-γ, IL-4 and IL-10) and antioxidant properties were gritty using qRT-PCR and ELISA kits, respectively, in experimental arthritic rats. Fluoxetine at 10, 20 and 40 mg/kg doses reduced (p < 0.001) the serum concentration of C-reactive protein and rheumatoid factor as well as suppressed the expression of PGE2, NF-kB, COX2 and INF-γ when compared to arthritic control. Moreover, fluoxetine (at higher doses) caused significant rise of IL-4 and IL-10. These findings supported the anti-inflammatory and antioxidant potential of fluoxetine in chronic inflammatory model and endorsed it for clinical trials.

    疼痛是人体的重要保护机制。它提醒我们潜在的组织损伤或伤害,并促进避免有害刺激。损伤诱导的炎症和组织损伤导致疼痛敏化,即使在最初的原发性损伤恢复后,也会放大对随后的有害刺激的反应。这种现象,通常被称为痛觉过敏启动,在雄性和雌性小鼠中进行了研究,以确定它是否对先前的损伤部位具有特异性。我们使用10μl的50%弗氏完全佐剂(CFA)施用于左后爪作为外周损伤的模型。雄性和雌性小鼠在CFA后都表现出强烈的部位特异性机械超敏反应,在注射后一周内解决。受伤解决后,只有雄性CFA引发的小鼠在对化学攻击或单次0.5mA电击脚时表现出增强和延长的机械敏感性。在CFA引发的雄性小鼠中,休克引起的机械性超敏反应在左(先前受伤)和右(未受伤)后爪中都有表达,提示在疼痛致敏表达中改变的集中过程具有关键作用。这些发现表明,疼痛史以性别特异性方式调节对随后的机械和化学疼痛刺激的感觉反应-在超出初始损伤部位的雄性小鼠中,足部休克诱导的痛觉过敏引发表达。
    Pain is a crucial protective mechanism for the body. It alerts us to potential tissue damage or injury and promotes the avoidance of harmful stimuli. Injury-induced inflammation and tissue damage lead to pain sensitization, which amplifies responses to subsequent noxious stimuli even after an initial primary injury has recovered. This phenomenon, commonly referred to as hyperalgesic priming, was investigated in male and female mice to determine whether it is specific to the site of previous injury. We used 10μl of 50 % Freund\'s complete adjuvant (CFA) administered to the left hind paw as a model of peripheral injury. Both male and female mice exhibited robust site-specific mechanical hypersensitivity after CFA, which resolved within one-week post-injection. After injury resolution, only male CFA-primed mice showed enhanced and prolonged mechanical sensitivity in response to a chemical challenge or a single 0.5 mA electric footshock. Among CFA-primed male mice, shock-induced mechanical hypersensitivity was expressed in both the left (previously injured) and the right (uninjured) hind paws, suggesting a pivotal role for altered centralized processes in the expression of pain sensitization. These findings indicate that pain history regulates sensory responses to subsequent mechanical and chemical pain stimuli in a sex-specific manner-foot-shock-induced hyperalgesic priming expression among male mice generalized beyond the initial injury site.

    这项研究的目的是检查卵巢切除术导致的雌激素水平变化之间的关系。和雌激素替代治疗(HRT)在大鼠的口面炎性疼痛模型。80只成年雌性Wistar大鼠最初分为2组:假手术或卵巢切除术(OVX-D1)。七天后(D7),大鼠接受弗氏完全佐剂(CFA)或盐水溶液单侧浸润至右侧颞下颌关节(TMJ).然后,大鼠接受17β-雌二醇(28µg/kg/天)或安慰剂21天(D10-D31).通过vonFrey(VF)和热板(HP)测试评估伤害感受,通过强迫游泳(FS)测试,以及类似抑郁的行为。在D32上,所有大鼠均被安乐死并血清,收集海马和脑干。CFA组出现机械性痛觉过敏,直至第21天(p≤0.05)。在HP组间没有观察到差异(p=0.735),以及FS的不动和游泳时间(分别为p=0.800;p=0.998)。在脑干,TNF-α水平差异有统计学意义(p=0.043),BDNF水平有边际显著差异(p=0.054),各组间海马BDNF和TNF-α水平无差异(p=0.232;p=0.081)。总之,激素替代疗法不能缓解去卵巢大鼠的口面部疼痛。然而,两种模型动物的脑干TNF-α水平均下降,HRT部分还原了。
    This study had the aim of examining the relationships between variations in estrogen levels resulting from ovariectomy, and estrogen hormone replacement therapy (HRT) in rats subjected to an orofacial inflammatory pain model. Eighty adult female Wistar rats were initially divided into 2 groups: Sham or ovariectomy (OVX-D1). Seven days later (D7), the rats were subjected to an unilateral infiltration of Freund\'s Complete Adjuvant (CFA) or saline solution into the right temporomandibular joint (TMJ). Then, rats received 17β-estradiol (28 µg/kg/day) or placebo for 21 days (D10-D31). Nociception was evaluated by the von Frey (VF) and the Hot Plate (HP) tests, and depressive-like behavior by the Forced Swimming (FS) test. On D32 all rats were euthanized and serum, hippocampus and brainstem were collected. The CFA groups presented a mechanical hyperalgesia until day 21 (p ≤ 0.05). No differences were observed among groups in the HP (p = 0.735), and in the immobility and swimming time of the FS (p = 0.800; p = 0.998, respectively). In the brainstem, there was a significant difference in the TNF-ɑ levels (p = 0.043), and a marginal significant difference in BDNF levels (p = 0.054), without differences among groups in the hippocampal BDNF and TNF-ɑ levels (p = 0.232; p = 0.081, respectively). In conclusion, the hormone replacement therapy did not alleviate orofacial pain in ovariectomized rats. However, there is a decrease in brainstem TNF-ɑ levels in the animals submitted to both models, which was partially reverted by HRT.

    疼痛的临床前评估通常依赖于行为测量和麻醉的神经生理学记录。当前的技术可以实现大规模的神经记录,然而,有可能在有意识的动物中揭示可量化的疼痛信号,用于临床前研究。虽然疼痛处理分布在许多大脑区域,考虑到其在疼痛的情感(“不愉快”)成分中的作用,前扣带回皮质(ACC)在分离这些信号方面特别感兴趣。这里,我们使用头戴式微型显微镜记录在Thy1启动子下自由移动的表达GCaMP6f的雄性小鼠中的钙瞬变,探索了ACC在临床前疼痛研究中的实用性。我们验证了GCaMP6f在兴奋性神经元中的表达,并且在该模型中没有发现内在的行为差异。使用跨天真的多模态刺激范式,疼痛,和镇痛条件,我们发现,虽然ACC人口活动大致与刺激强度成比例,单细胞表示是高度灵活的。我们发现CFA后人口活动仅有低幅度的增加,并且没有足够的证据表明ACC中存在强大的伤害性集合。然而,我们发现,在CFA诱导的炎性疼痛后(但不是之前),在存在机制上不同的镇痛药加巴喷丁或布洛芬的情况下,应答持续时间随时间急剧增加,并且成对神经相关性普遍增加.这种增加不能仅通过运动的变化来解释。一起来看,这些结果凸显了在ACC中的柔性表征中分离不同疼痛信号的挑战,但提示疼痛后镇痛的神经生理学标志可推广到至少两种镇痛药.意义陈述我们的研究测量了转基因小鼠的前扣带回皮质(ACC)中的神经活动,以改善临床前模型中的疼痛和镇痛措施。我们发现,尽管ACC人口活动随刺激强度而缩放,并且可以解码,感觉刺激的单细胞表征是灵活的。疼痛后观察到ACC群体活动的低幅度增加,但由疼痛/镇痛引起的特定活动变化的亚群难以从内在变异性中消除歧义。有趣的是,在CFA后存在两种不同的镇痛药的情况下,反应在时间上增强,并表现出细胞间相关性增加。这些仅在疼痛后发生的镇痛的独特神经特征可能会扩大我们对疼痛和镇痛的中枢机制的理解。
    Preclinical assessments of pain have often relied upon behavioral measurements and anesthetized neurophysiological recordings. Current technologies enabling large-scale neural recordings, however, have the potential to unveil quantifiable pain signals in conscious animals for preclinical studies. Although pain processing is distributed across many brain regions, the anterior cingulate cortex (ACC) is of particular interest in isolating these signals given its suggested role in the affective (\"unpleasant\") component of pain. Here, we explored the utility of the ACC toward preclinical pain research using head-mounted miniaturized microscopes to record calcium transients in freely moving male mice expressing genetically encoded calcium indicator 6f (GCaMP6f) under the Thy1 promoter. We verified the expression of GCaMP6f in excitatory neurons and found no intrinsic behavioral differences in this model. Using a multimodal stimulation paradigm across naive, pain, and analgesic conditions, we found that while ACC population activity roughly scaled with stimulus intensity, single-cell representations were highly flexible. We found only low-magnitude increases in population activity after complete Freund\'s adjuvant (CFA) and insufficient evidence for the existence of a robust nociceptive ensemble in the ACC. However, we found a temporal sharpening of response durations and generalized increases in pairwise neural correlations in the presence of the mechanistically distinct analgesics gabapentin or ibuprofen after (but not before) CFA-induced inflammatory pain. This increase was not explainable by changes in locomotion alone. Taken together, these results highlight challenges in isolating distinct pain signals among flexible representations in the ACC but suggest a neurophysiological hallmark of analgesia after pain that generalizes to at least two analgesics.

    熊果苷,天然可溶的糖基化苯酚具有抗氧化剂,抗菌,抗肿瘤和抗炎特性。目前的探索评价了在CFA诱导的大鼠关节炎模型中通过口服熊果苷(25、50和100mg/kg)来治疗关节炎。体重变化,爪子大小,记录关节炎大鼠的关节直径,直至第28天。血液学,生物化学,通过麻醉大鼠的血液样本测量氧化和炎症生物标志物。熊果苷明显减少爪体积,PGE-2,抗CCP和5-LOX水平,然而,维持代谢和血液平衡,防止体重减轻。大鼠踝关节的放射学和组织学改变明显改善。此外,熊果苷增加了IL-10和IL-4等基因指针,同时显着降低了CRP和WBC的水平,而Hb,治疗后血小板和红细胞计数明显增加。SOD的抗氧化水平,治疗组CAT和GSH改善,MDA水平降低。Rt-PCR研究显示白细胞介素-1β显著降低,TNF-α,白细胞介素-6,环氧合酶-2,NF-κB和IL-17以及IL-4和IL-10等基因指针在治疗组中的表达增加。分子对接的评估显示熊果苷对5-LOX的强结合相互作用,IL-17,TNF-α和白细胞介素-6,环氧合酶-2,核因子-κB,IL-4和iNOS提供了实验和理论结果之间的强关联。因此,熊果苷通过调节抗炎细胞因子可显着降低CFA诱导的关节炎,即,IL-10和IL-4,促炎细胞因子组,如NF-κB,TNF-α,IL-1β,IL-6、PGE-2、5-LOX和COX-2和氧化生物标志物。
    Arbutin, a naturally soluble glycosylated phenol has antioxidant, antimicrobial, antitumor and anti-inflammatory properties. The current exploration appraises the treatment of arthritis by use of Arbutin (25, 50 and 100 mg/kg) orally in CFA-induced rat arthritis model. Body weight changes, paw size, and joint diameter were recorded till the 28th day in the arthritic-induced rats. Hematological, biochemical, oxidative and inflammatory biomarkers were measured through the blood samples of anesthetized rats. Arbutin markedly decreased paw volume, PGE-2, anti-CCP and 5-LOX levels, however, maintained metabolic and hematological balance and prevented weight loss. Radiology and histology changes improved significantly in the ankle joints of rats. Moreover, Arbutin increased gene pointers such as IL-10 and IL-4 while significantly reducing the levels of CRP and WBCs, whereas Hb, platelets and RBCs count markedly raised in post-treatments. Antioxidant levels of SOD, CAT and GSH were improved and MDA level was reduced in treated groups. Rt-PCR investigation showed a significant reduction of the interleukin-1β, TNF-α, interleukin-6, cyclooxygenase-2, NF-κB and IL-17 and increased expression of gene pointers like IL-4, and IL-10 in treated groups. Assessment of molecular docking revealed a strong binding interaction of Arbutin against 5-LOX, IL-17, TNF-alpha and interleukin-6, cyclooxygenase-2, nuclear factor-κB, IL-4 and iNOS providing a strong association between experimental and theoretical results. As a result, Arbutin has significantly reduced CFA-induced arthritis by modulation of anti-inflammatory cytokines, i.e., IL-10 and IL-4, the pro-inflammatory cytokines panel such as NF-κB, TNF-alpha, IL-1β, IL-6, PGE-2, 5-LOX and COX-2 and oxidative biomarkers.

    背景:由于外周动脉疾病(PAD)治疗技术的快速发展,目前主要是介入性治疗。股总动脉(CFA)病变是一个例外,应根据血管指南进行手术治疗。然而,最近的证据表明,血管内技术,例如支架术,具有相当的临床结果,同时引起更少的并发症。本分析的目的是评估单中心CFA病变血管内治疗的疗效。所有人登记。患者和方法:纳入2017年01月至2020年12月在耶拿大学医院I内科接受CFA病变治疗的所有患者。通过评估介入前后以及随访后(FU)的踝肱指数(ABI)来确定治疗成功。测量步行距离(WD)和目标血运重建率(TLR)和主要通畅率(PPR)。结果:分析包括109例患者,平均年龄73.4岁,其中67%(73)是男性。72例患者接受介入治疗,而手术治疗33例,保守治疗4例。整个队列中的静息ABI显示干预后从0.5增加到0.7(p=<0.05;平均FU时间:6.5个月)。在介入队列中,ABI在FU时从0.6增加到0.8(p=<0.05;平均FU时间:5,8个月),在手术治疗组中从0.3增加到0.6(p=<0.05;平均FU时间:8,8个月)。在整个集体中,WD从116.5米(m)提高到152.5米(p=<0.05)。在本分析中,TLR在介入治疗后为8.1%,在血管手术后为6.1%(p=0.72),PPR在EVT后为89.8%,在手术入路后为90.9%(p=0.87)。介入组介入术中/后并发症发生率为5.5%,手术治疗组术后并发症发生率为15.2%。结论:本分析表明,即使在现实世界中,所有人的集体,CFA病变的介入治疗与手术治疗的患者队列一样安全有效.继续生成注册表数据对于最终启动范式转换很重要。
    Background: Due to the rapid development of treatment techniques of peripheral arterial disease (PAD) treatment is nowadays predominantly interventional. An exception are lesions of the common femoral artery (CFA), which should be treated surgically according to vascular guidelines. However, recent evidence has shown that endovascular techniques, e.g. stenting, have comparable clinical outcomes while causing fewer complications. The aim of the present analysis was to evaluate the therapeutic success of endovascular therapy of CFA lesions in a single center, all - comers registry. Patients and methods: All patients who were treated for a CFA lesion at the Department of Internal Medicine I of the University Hospital Jena in the period from 01/2017 to 12/2020 were included. Treatment success was determined by evaluating the ankle-brachial-index (ABI) pre- and post-interventional as well as after follow-up (FU), measuring walking distance (WD) and by target revascularization rate (TLR) and primary patency rate (PPR). Results: The analysis included 109 patients with a mean age of 73.4 years, with 67% (73) of those being men. 72 patients received interventional treatment, whereas 33 were treated surgically and 4 conservatively. Resting ABI in the overall cohort showed an increase from 0.5 to 0.7 post intervention (p=<0.05; mean FU-time: 6.5 months). In the interventional cohort ABI increases from 0.6 to 0.8 (p=<0.05; mean FU-time: 5,8 months) at FU and from 0.3 to 0.6 (p=<0.05; mean FU-time: 8,8 month) in the surgically treated group. The WD improved in the whole collective from 116.5 meter (m) to 152.5 m (p=<0.05). The TLR showed no significant difference with 8.1% after interventional treatment and 6.1% after vascular surgery in the present analysis (p=0.72) as well as PPR with 89.8% after EVT and 90.9% after surgical approach (p=0.87). The intra-/postinterventional complication rate was 5.5% in the intervention group, compared to postoperative complication rate of 15.2% in the surgically treated group. Conclusions: The present analysis demonstrates that even in a real-world, all-comers collective, interventional therapy for CFA lesions was safe and equally effective as the surgically treated patient cohort. Continuing to generate registry data is important to eventually initiate a paradigm shift.

    微生物(M.B)Benth已被证明具有抗炎功效,因此,本研究的目的是评估M.B乙醇提取物和组分的抗关节炎潜能,并研究可能的作用机制.使用甲醛提示的关节炎模型评估M.B对急性关节炎表现的有效性,而在Sprague-Dawley大鼠中使用称为完全弗氏佐剂的慢性模型。每周对涉及爪子体积的参数进行评估,体重,和关节炎评分;在CFA模型完成后,血液学,生化和氧化应激参数以及各种介质的水平(PGE2,IL-1β,TNFα,IL6,MMP2,3,9,VEGF,NF-B,评估IL-10和IL-4)。结果表明,该植物通过显示爪子体积的显著减少来治疗关节炎的能力,关节炎评分,和组织学特征。NF-B的水平,MMP2,3,9,IL6,IL1β,TNFα,用植物提取物和组分处理后,VEGF均显着降低。植物提取物及其部分基本上保存了体重减轻,氧化应激标志物和IL-4和1L-10的水平。PGE2水平也显示在治疗组中降低,支持M.B免疫调节能力。M.B给药后血液学和生化指标也恢复正常。研究结果验证了M.B的抗关节炎和免疫调节属性可能是通过调节氧化应激,炎症,促炎和抗炎生物标志物。
    Micromeria biflora (M.B) Benth has proven anti-inflammatory efficacy, thereby, the goal of the current investigation was to assess the anti-arthritic potential of M.B ethanolic extract and fractions as well as to investigate the likely mechanism of action. The effectiveness of M.B against acute arthritic manifestations was assessed using an arthritic model prompted by formaldehyde, whereas a chronic model was developed using an adjuvant called Complete Freund\'s in Sprague-Dawley rats. Weekly evaluations were conducted for parameters involving paw volume, body weight, and arthritic score; at the completion of the CFA model, hematological, biochemical and oxidative stress parameters as well as the level of various mediators (PGE2, IL-1β, TNFα, IL6, MMP2, 3, 9, VEGF, NF-ĸB, IL-10, and IL-4) were evaluated. The results demonstrated the plant\'s ability to treat arthritis by showing a significant decrease in paw volume, arthritic score, and histological characteristics. The levels of NF-ĸB, MMP2, 3, 9, IL6, IL1β, TNFα, and VEGF were all significantly reduced after treatment with plant extract and fractions. Plant extract and its fractions substantially preserved body weight loss, oxidative stress markers and levels of IL-4 and 1L-10. PGE2 levels were also shown to be reduced in the treatment groups, supporting the M.B immunomodulatory ability. Hematological and biochemical indicators were also normalized after M.B administration. Outcomes of the study validated the anti-arthritic and immunomodulatory attributes of M.B probably through modulating oxidative stress, inflammatory, pro-inflammatory and anti-inflammatory biomarkers.

    背景:DSM-5对创伤后应激障碍(PTSD)诊断标准的改变导致修改了评估PTSD的最广泛使用的工具,即DSM-5创伤后检查表(PCL-5)。目的:本研究检查了罗马尼亚版本的PCL-5的心理测量特性,测试了其针对DSM-5(SCID-5)的结构化临床访谈的诊断效用,并通过相关症状模型和双因素模型研究了PTSD症状的潜在结构。方法:总共使用727名参与者的样本来测试PCL-5的心理测量特性和潜在结构,并使用SCID-5对101名个体进行了临床访谈。进行了受试者工作特征曲线(ROC)分析,以测试PCL-5的诊断效用,并根据YoudenJ指数确定最佳截止分数。进行了验证性因素分析(CFA)和双因素模型来研究PTSD症状的潜在结构。结果:估计显示,与SCID-5诊断相比,PCL-5是诊断准确性可接受的有价值的工具,表示截止分数>47。CFA为Anhedonia提供了经验支持,Hybrid,和双因素模型。通过使用回顾性的研究结果是有限的,自我报告数据和女性参与者的高比例。结论:PCL-5是一种心理上健全的工具,可用于在社区样本中进行临时诊断并改善创伤知情实践。
    本研究对DSM-5(PCL-5)的罗马尼亚版创伤后应激障碍清单进行了深入分析。探索它的心理测量特性,诊断实用程序,和潜在的结构。使用SCID-5确定了PTSD诊断的最佳截止分数,提供了对诊断过程的重要见解并增强了其在临床评估中的实用性。使用双因素建模和其他统计方法,各种创伤后应激障碍模型进行了比较,为未来的研究提供有价值的指导,评估,在这一领域的干预。
    Background: The changes DSM-5 brought to the diagnostic criteria for posttraumatic stress disorder (PTSD) resulted in revising the most widely used instrument in assessing PTSD, namely the Posttraumatic Checklist for DSM-5 (PCL-5).Objective: This study examined the psychometric properties of the Romanian version of the PCL-5, tested its diagnostic utility against the Structured Clinical Interview for DSM-5 (SCID-5), and investigated the latent structure of PTSD symptoms through correlated symptom models and bifactor modelling.Method: A total sample of 727 participants was used to test the psychometric properties and underlying structure of the PCL-5 and 101 individuals underwent clinical interviews using SCID-5. Receiver operating characteristic curve (ROC) analyses were performed to test the diagnostic utility of the PCL-5 and identify optimal cut-off scores based on Youden\'s J index. Confirmatory Factor Analyses (CFAs) and bifactor modelling were performed to investigate the latent structure of PTSD symptoms.Results: Estimates revealed that the PCL-5 is a valuable tool with acceptable diagnostic accuracy compared to SCID-5 diagnoses, indicating a cut-off score of >47. The CFAs provide empirical support for Anhedonia, Hybrid, and bifactor models. The findings are limited by using retrospective, self-report data and the high percentage of female participants.Conclusions: The PCL-5 is a psychometrically sound instrument that can be useful in making provisional diagnoses within community samples and improving trauma-informed practices.
    This study offers an in-depth analysis of the Romanian version of the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), exploring its psychometric properties, diagnostic utility, and latent structure.An optimal cut-off score was identified for PTSD diagnosis using the SCID-5, providing essential insights into the diagnostic process and enhancing its utility in clinical assessments.Using bifactor modelling and other statistical methods, various PTSD models were compared to offer valuable guidance for future research, assessment, and interventions in this field.

    Onosmabracteatum墙(O.bracteatum)传统上用于治疗关节炎;但是,其治疗潜力值得进一步调查。本研究旨在评估O.rabteatum叶(AeOB)的水乙醇提取物在完全弗氏佐剂(CFA)诱导的关节炎大鼠模型中的抗关节炎作用。用AeOB(250、500和750mg/kg)治疗大鼠,吲哚美辛(10mg/kg),或注射CFA后第8至28天的媒介物对照。关节炎评分,爪子直径,定期监测体重。进行X线片和组织病理学分析以评估关节炎的严重程度。炎性细胞因子肿瘤坏死因子-α(TNF-α),白细胞介素-6(IL-6),通过qPCR和显微照片定量C反应蛋白(CRP)。AeOB的植物化学分析揭示了生物碱,黄酮类化合物,酚类物质,单宁,皂甙,和糖苷。AeOB在DPPH测定中还表现出抗氧化潜力,IC50为73.22µg/mL。AeOB和双氯芬酸具有抗炎和抗关节炎活性。与CFA对照相比,用750mg/kg的AeOB和吲哚美辛处理的大鼠显示出显著降低的关节炎症状和关节炎症。与关节炎大鼠相比,AeOB治疗下调TNF-α和IL-6并降低CRP水平。X线摄影和组织病理学也显示预后改善。这些发现证明了AeOB叶的抗关节炎潜力。
    Onosma bracteatum Wall (O. bracteatum) has been used traditionally for the management of arthritis; however, its therapeutic potential warrants further investigation. This study aimed to evaluate the anti-arthritic effects of the aqueous-ethanolic extract of O. bracteatum leaves (AeOB) in a rat model of complete Freund\'s adjuvant (CFA)-induced arthritis. Rats were treated with AeOB (250, 500, and 750 mg/kg), indomethacin (10 mg/kg), or a vehicle control from days 8 to 28 post-CFA injection. Arthritic score, paw diameter, and body weight were monitored at regular intervals. X-ray radiographs and histopathological analysis were performed to assess arthritic severity. Inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP) were quantified by qPCR and icromatography. Phytochemical analysis of AeOB revealed alkaloids, flavonoids, phenols, tannins, Saponins, and glycosides. AeOB also exhibited antioxidant potential with an IC50 of 73.22 µg/mL in a DPPH assay. AeOB and diclofenac exhibited anti-inflammatory and anti-arthritic activities. Rats treated with AeOB at 750 mg/kg and indomethacin showed significantly reduced arthritic symptoms and joint inflammation versus the CFA control. The AeOB treatment downregulated TNF-α and IL-6 and decreased CRP levels compared with arthritic rats. Radiography and histopathology also showed improved prognosis. These findings demonstrate the anti-arthritic potential of AeOB leaves.
