    目的:尽管焦磷酸钙沉积(CPPD)自1960年代以来就已为人所知,我们对其发病机制的理解仍然是初步的。本文旨在阐明焦磷酸钙(CPP)晶体形成和沉积的已知机制,并探讨未来的研究方向。通过研究各种观点,从基础研究到临床和影像学评估,以及新出现的方法,我们可以为更深入地理解CPPD的发病机制建立一个起点。
    结果:近年来,CPPD研究取得了重大进展,特别是在临床领域,随着2023年CPPD疾病ACR/EULAR分类标准的发展,并在引入OMERACT超声诊断和评分系统的情况下进行成像。然而,基础研究进展缓慢。新的实验室方法,如拉曼光谱和组学科学,提供有希望的见解,可能有助于拼凑CPPD的难题。CPPD是一种常见但尚未充分研究的疾病。随着人口老龄化和CPPD变得越来越普遍,迫切需要更好地了解这种疾病以及晶体形成和沉积所涉及的机制,以改善诊断和治疗方法。
    OBJECTIVE: Although calcium pyrophosphate deposition (CPPD) has been known since the 1960s, our understanding of its pathogenesis remains rudimentary. This review aims to illustrate the known mechanisms underlying calcium pyrophosphate (CPP) crystal formation and deposition and explore future directions in research. By examining various perspectives, from basic research to clinical and imaging assessments, as well as new emerging methodologies, we can establish a starting point for a deeper understanding of CPPD pathogenesis.
    RESULTS: Recent years have seen significant advances in CPPD research, particularly in the clinical field with the development of the 2023 ACR/EULAR classification criteria for CPPD disease, and in imaging with the introduction of the OMERACT ultrasonographic definitions and scoring system. However, progress in basic research has been slower. New laboratory approaches, such as Raman spectroscopy and omics sciences, offer promising insights that may help piece together the puzzle of CPPD. CPPD is a common yet understudied condition. As the population ages and CPPD becomes more prevalent, there is an urgent need to better understand the disease and the mechanisms involved in crystal formation and deposition, in order to improve diagnosis and therapeutic approaches.

    近排腕关节切除术(PRC)是腕关节关节炎治疗的主要手段;然而,传统上,它是在受影响的头状患者中禁忌的。先前已经描述了使用软组织介入移植物来重新覆盖放射性足关节,以允许在这些患者中使用PRC。在目前的研究中,我们回顾了我们使用膝关节半月板同种异体移植修复放射性关节的结果,这些患者原本是PRC的禁忌症患者.
    从2011年至2022年对接受PRC的患者进行了回顾性研究,该患者有或没有半月板间置术。患者人口统计学(年龄,性别,职业,手支配,等)被收集。疼痛的改善是主要结果。手腕运动范围和需要融合的重建失败是次要结果。
    我们确定了83例患者,其中43例符合纳入标准。15例患者(35%)接受PRC与半月板间置关节成形术,28例患者(65%)仅接受PRC。有或没有半月板间置关节成形术的患者术后疼痛改善(93%vs95%,P>0.05),中位随访时间为11(范围,3-38个月)和9个月(范围,3-64个月),分别。与单独PRC相比,接受半月板间置关节成形术的患者术后腕关节活动范围(屈曲:9vs-4,P>.05,伸展:12vs-4,P=.10)趋于增加。
    我们对终末期腕关节关节炎患者进行PRC和半月板间置关节成形术的短期至中期结果与单独PRC的患者相当。
    UNASSIGNED: Proximal row carpectomy (PRC) is a mainstay of wrist arthritis treatment; however, it is traditionally contraindicated in patients with an affected capitate. The use of soft tissue interposition grafts to resurface the radiocapitate articulation has been previously described to allow for PRC in these patients. In the current study, we reviewed our outcomes using knee meniscus allograft interposition to resurface the radiocapitate articulation in patients who would have otherwise been contraindicated for PRC.
    UNASSIGNED: A retrospective study of patients who underwent PRC with or without meniscus interposition arthroplasty was performed from 2011 to 2022. Patient demographics (age, sex, occupation, hand dominance, etc) were collected. Improvement in pain was the primary outcome. Wrist range of motion and reconstructive failure requiring fusion were the secondary outcomes.
    UNASSIGNED: We identified a total of 83 patients and 43 met the inclusion criteria. Fifteen patients (35%) underwent PRC with meniscus interposition arthroplasty, and 28 patients (65%) underwent PRC alone. Patients with and without meniscus interposition arthroplasty had documented improvement in pain postoperatively (93% vs 95%, P > .05) at a median follow-up time of 11 (range, 3-38 months) and 9 months (range, 3-64 months), respectively. Postoperative wrist range of motion (flexion: +9 vs -4, P > .05, extension: +12 vs -4, P = .10) trended toward increase in patients undergoing meniscus interposition arthroplasty compared with PRC alone.
    UNASSIGNED: Our short- to mid-term outcomes in patients with end-stage wrist arthritis affecting the capitate who undergo PRC and meniscus interposition arthroplasty are comparable with those receiving PRC alone.

    先天性膈疝(CDH)是一种以肺发育异常为特征的复杂发育异常,膈肌缺损和心功能不全.尽管CDH的管理取得了重大进展,死亡率和发病率继续由肺发育不全驱动,肺动脉高压,和心脏功能障碍。CDH的病因尚不清楚,但是CDH被认为是由遗传易感性和外部/环境因素共同引起的。当前的研究采用多组学技术来研究CDH固有的分子谱和途径。目的是发现潜在的发病机制,新的生物标志物和最终新的治疗靶点。干细胞和它们的货物,非编码RNA和靶向炎症和血管重塑的药物在使用CDH动物模型的临床前研究中产生了有希望的结果.当前疗法的缺点以及对CDH发病机理的更好理解已经产生了新的有希望的实验治疗,目前正在临床试验中进行评估。这篇综述提供了对转化研究当前发展的见解,从CDH异常心肺发育的细胞起源,以及在工作台临床前CDH模型中鉴定新的治疗靶标,并将其转化为床边的临床试验。
    Congenital Diaphragmatic Hernia (CDH) is a complex developmental abnormality characterized by abnormal lung development, a diaphragmatic defect and cardiac dysfunction. Despite significant advances in management of CDH, mortality and morbidity continue to be driven by pulmonary hypoplasia, pulmonary hypertension, and cardiac dysfunction. The etiology of CDH remains unknown, but CDH is presumed to be caused by a combination of genetic susceptibility and external/environmental factors. Current research employs multi-omics technologies to investigate the molecular profile and pathways inherent to CDH. The aim is to discover the underlying pathogenesis, new biomarkers and ultimately novel therapeutic targets. Stem cells and their cargo, non-coding RNAs and agents targeting inflammation and vascular remodeling have produced promising results in preclinical studies using animal models of CDH. Shortcomings in current therapies combined with an improved understanding of the pathogenesis in CDH have given rise to novel promising experimental treatments that are currently being evaluated in clinical trials. This review provides insight into current developments in translational research, ranging from the cellular origins of abnormal cardiopulmonary development in CDH and the identification of novel treatment targets in preclinical CDH models at the bench and their translation to clinical trials at the bedside.

    转化研究将实验室生成的科学发现应用于现实世界的实践,目的是加强更快速的健康挑战解决方案。2023年,这篇社论的作者(希尔德布兰特和戈德施密特)旨在为《国际饮食失调杂志》(IJED)开发一期特刊,重点是翻译饮食失调研究。这个问题的目标是开始缩小基础和应用研究之间的差距,通过征集文章,提高我们对导致或维持饮食失调的机制的理解,这可能会导致更强大的研究进展和向公众传播信息。该问题的进一步目标包括使IJED的读者接受广泛的翻译研究,并激发新的合作努力。虽然收到了强有力的意见书,在征集足够多的文章时遇到了挑战,这可能反映了饮食失调领域基础和临床科学家之间长期存在的沟通障碍。在这篇社论中,我们强调特别部分中包含的工作,确定翻译饮食失调研究中的潜在障碍,并提供多管齐下的方法来支持整个翻译谱更快的进展。通过改进我们的领域如何进行转化研究,我们可以为那些有饮食失调或有饮食失调风险的人带来更好的结果。
    Translational research applies laboratory-generated scientific discoveries to real-world practice with the goal of potentiating more rapid solutions to health challenges. In 2023, the authors of this editorial (Hildebrandt and Goldschmidt) aimed to develop a special issue for the International Journal of Eating Disorders (IJED) focusing on translational eating disorder research. The goal for this issue was to begin closing the gap between basic and applied research by soliciting articles that improve our understanding of mechanisms that cause or maintain eating disorders, which could result in more robust research advances and dissemination of information to the public. Further goals for the issue included exposing IJED\'s readership to a wide range of translational research and inspiring new collaborative efforts. While strong submissions were received, challenges were encountered in soliciting enough articles, potentially reflecting long-standing communication barriers between basic and clinical scientists within the eating disorders field. In this editorial, we highlight work included in the special section, identify potential barriers in translational eating disorder research, and offer a multipronged approach to support more rapid progress across the translational spectrum. By improving how our field approaches translational research, we can promote better outcomes for those with or at risk for eating disorders.

    临床医生对基因组学知识的信心不足是将基因组学整合到主流医学中的主要障碍。这里,我们评估了即将毕业的英国医学生的基因组学信心.
    我们在研究的最后两年对英国医学生进行了一项基于网络的全国性调查,参与者对他们对基因组学概念的信心进行了评估。
    总共,来自19所医学院的145名医学生参加了会议。学生报告接受基因组学教学的数量与基因组学信心呈正相关,对基础科学教学的影响最大。虽然人们对核心基因组学原理的信心很高,比如DNA之间的区别,基因和染色体(95%),基因组学临床应用的信心下降-只有50%报告对疾病的遗传贡献有很好的了解,28%报告对临床使用的基因组测试有很好的了解。总的来说,59%的人报告对变体解释的理解很差;然而,超过一半的人报告接受了“大量”的基因组医学教学,他们报告说对这个主题有很好的理解。
    本文确定了基因组学知识和驱动因素的差距,强调需要改进本科基因组学教育,为未来的医生在基因组学时代自信地实践做好准备。
    UNASSIGNED: Low confidence in genomics knowledge among clinicians is a major barrier to the integration of genomics into mainstream medicine. Here, we assessed the genomics confidence of UK medical students approaching graduation.
    UNASSIGNED: We conducted a web-based nationwide survey of UK medical students in the final 2 years of study where participants rated their confidence in genomics concepts.
    UNASSIGNED: In total, 145 medical students across 19 medical schools participated. The amount of genomics teaching students reported receiving was positively associated with genomics confidence, with the amount of basic science teaching having the strongest influence. While confidence was high in core genomics principles, such as the difference between DNA, genes and chromosomes (95%), confidence dropped in clinical applications of genomics - only 50% reported a good understanding of the genetic contribution to disease and 28% reported good knowledge of clinically used genomic tests. Overall, 59% reported a poor understanding of variant interpretation; however, over half who reported receiving \'lots\' of genomic medicine teaching reported a good understanding of this topic.
    UNASSIGNED: Gaps in genomics knowledge and drivers in confidence have been identified herein, highlighting the need for improvements in undergraduate genomics education to prepare future doctors to confidently practise in the genomics era.

    以1980年代的初步工作为基础,证明了在脑缺血中的移植物活力,干细胞移植在促进生存方面显示出巨大的希望,增强神经保护和诱导神经再生,同时减轻经常伴随缺血性卒中的组织学和行为缺陷。这些发现导致了许多临床试验,这些临床试验彻底支持了患者干细胞治疗的强大安全性,但产生了可变的疗效。随着临床前证据继续扩大,通过新细胞系的研究和干细胞递送的优化,对于转化模型来说,遵守通过基础科学研究建立的协议仍然至关重要。随着最近将干细胞作为联合治疗与标准溶栓治疗方法一起使用的方法的转变,关键问题包括时机,给药途径,和干细胞类型都必须从实验室适当翻译,以解决干细胞对脑缺血的功效问题,最终将增强中风患者的治疗方法,以改善生活质量。
    With a foundation built upon initial work from the 1980s demonstrating graft viability in cerebral ischemia, stem cell transplantation has shown immense promise in promoting survival, enhancing neuroprotection and inducing neuroregeneration, while mitigating both histological and behavioral deficits that frequently accompany ischemic stroke. These findings have led to a number of clinical trials that have thoroughly supported a strong safety profile for stem cell therapy in patients but have generated variable efficacy. As preclinical evidence continues to expand through the investigation of new cell lines and optimization of stem cell delivery, it remains critical for translational models to adhere to the protocols established through basic scientific research. With the recent shift in approach towards utilization of stem cells as a conjunctive therapy alongside standard thrombolytic treatments, key issues including timing, route of administration, and stem cell type must each be appropriately translated from the laboratory in order to resolve the question of stem cell efficacy for cerebral ischemia that ultimately will enhance therapeutics for stroke patients towards improving quality of life.
