    抗胸腺细胞球蛋白(ATG)是实体器官移植免疫抑制的基石。治疗是由过度免疫抑制引起的并发症(如感染和癌症)与由免疫抑制不足引起的排斥之间的微妙平衡。CD3+T淋巴细胞测量经常用于治疗监测。然而,这种分析成本很高,而且并不总是容易获得。这项研究的目的是根据我们移植中心的数据并结合文献综述,研究淋巴细胞总数是否可以代替CD3T淋巴细胞的测量。假设是总淋巴细胞计数可以作为CD3T淋巴细胞的诊断替代标记。
    进行了一项回顾性队列研究,包括接受肾脏和/或胰腺移植并接受ATG诱导治疗或排斥治疗的患者.纳入标准是在同一天同时测量总淋巴细胞计数和CD3T淋巴细胞测量值。此外,截至2023年10月18日,PubMed和Embase进行了关于实体器官移植的已发表研究,ATG,T淋巴细胞,淋巴细胞计数,和监测。在回顾性队列研究中,在2016年至2023年期间,共有91名患者移植,487个样本,包括在内。
    低于0.3×109/L的总淋巴细胞计数作为低于0.05×109/L的CD3+T淋巴细胞的替代标记具有很高的敏感性(86%),但总淋巴细胞计数高于0.3×109/L的特异性较低(52%),作为CD3+T淋巴细胞高于0.05×109/L的替代标记。对文献的回顾确定了七项在ATG监测中比较总淋巴细胞计数和CD3T淋巴细胞的研究。这些研究支持使用低总淋巴细胞计数作为CD3+T淋巴细胞的替代标记和省略ATG治疗的指标。然而,对于高总淋巴细胞计数作为继续治疗的指标尚无共识.
    结果支持当低于0.3x109/L时,总淋巴细胞计数可用于省略ATG治疗,而CD3T淋巴细胞分析应保留用于较高的总淋巴细胞计数,以避免ATG过度治疗。
    UNASSIGNED: Anti-Thymocyte Globulin (ATG) is a cornerstone in immune suppression for solid organ transplantation. The treatment is a delicate balance between complications arising from over-immunosuppression such as infections and cancer versus rejection stemming from under-immunosuppression. CD3+ T-lymphocyte measurements are frequently employed for treatment monitoring. However, this analysis is costly and not always accessible. The aim of this study was to investigate whether the total count of lymphocytes could replace CD3+ T-lymphocyte measurements based on data from our transplantation center combined with a review of the literature. The hypothesis was that the total lymphocyte count could serve as a diagnostic surrogate marker for CD3+ T-lymphocytes.
    UNASSIGNED: A retrospective cohort study was conducted, including patients who underwent kidney and/or a pancreas transplantation and received ATG as induction therapy or for rejection treatment. The inclusion criterium was that the total lymphocyte count and CD3+ T-lymphocyte measurements were measured simultaneously on the same day. Additionally, PubMed and Embase were searched up to 18/10/2023 for published studies on solid organ transplantation, ATG, T-lymphocytes, lymphocyte count, and monitoring. In the retrospective cohort study, a total of 91 patients transplanted between 2016 and 2023, with 487 samples, were included.
    UNASSIGNED: Total lymphocyte counts below 0.3 x 109/L had a high sensitivity (86%) as a surrogate marker of CD3+ T-lymphocytes below 0.05 x 109/L, but the specificity was low (52%) for total lymphocyte counts above 0.3 x 109/L as a surrogate marker for CD3+ T-lymphocytes above 0.05 x 109/L. A review of the literature identified seven studies comparing total lymphocyte counts and CD3+ T-lymphocytes in ATG monitoring. These studies supported the use of a low total lymphocyte count as a surrogate marker for CD3+ T-lymphocytes and an indicator to omit ATG treatment. However, there was no consensus regarding high total lymphocyte counts as an indicator for continued treatment.
    UNASSIGNED: Results supports that the total lymphocyte count can be used to omit ATG treatment when below 0.3 x 109/L whereas the CD3+ T-lymphocyte analysis should be reserved for higher total lymphocyte counts to avoid ATG overtreatment.

    肝移植(LT)是肝细胞癌(HCC)的主要治疗方法之一。米兰标准长期以来一直适用于HCC的候选LT患者。然而,米兰标准的应用未能准确预测有复发风险的患者.因此,我们的目标是建立并验证与米兰标准相比的深度学习模型,并更好地指导LT治疗后。
    总共对356名接受LT的HCC患者进行了评估,并获得了完整的随访数据。将整个队列随机分为训练集(n=286)和验证集(n=70)。首次使用pycox库提供的多层感知器模型构建复发预测模型。然后,结合了深度学习和表格数据处理技术的元素的表格神经网络(TabNet)被用来与米兰标准进行比较,并验证了我们提出的模型的性能。
    肿瘤大小超过7厘米的患者,肿瘤分级分化较差和多个肿瘤数量首次被归类为高复发风险.我们用TabNet训练了一个分类模型,我们提出的模型在准确性方面优于米兰标准(0.95vs.0.86,p<0.05)。此外,我们的模型显示出更好的性能结果和改进的AUC,NRI和危险比,证明了模型的鲁棒性。
    基于TabNet对HCC患者的各种参数的使用,提出了一种预后模型。该模型在LT后复发预测和高危亚组识别中表现良好。
    UNASSIGNED: Liver transplantation (LT) is one of the main curative treatments for hepatocellular carcinoma (HCC). Milan criteria has long been applied to candidate LT patients with HCC. However, the application of Milan criteria failed to precisely predict patients at risk of recurrence. As a result, we aimed to establish and validate a deep learning model comparing with Milan criteria and better guide post-LT treatment.
    UNASSIGNED: A total of 356 HCC patients who received LT with complete follow-up data were evaluated. The entire cohort was randomly divided into training set (n = 286) and validation set (n = 70). Multi-layer-perceptron model provided by pycox library was first used to construct the recurrence prediction model. Then tabular neural network (TabNet) that combines elements of deep learning and tabular data processing techniques was utilized to compare with Milan criteria and verify the performance of the model we proposed.
    UNASSIGNED: Patients with larger tumor size over 7 cm, poorer differentiation of tumor grade and multiple tumor numbers were first classified as high risk of recurrence. We trained a classification model with TabNet and our proposed model performed better than the Milan criteria in terms of accuracy (0.95 vs. 0.86, p < 0.05). In addition, our model showed better performance results with improved AUC, NRI and hazard ratio, proving the robustness of the model.
    UNASSIGNED: A prognostic model had been proposed based on the use of TabNet on various parameters from HCC patients. The model performed well in post-LT recurrence prediction and the identification of high-risk subgroups.

    在这项研究中,分析了10年的采购质量监测数据,以确定与采购相关损伤相关的潜在风险因素及其与移植物长期存活的关系。所有死去的肾脏,肝脏,和2012年至2022年的胰腺供体及其在荷兰的相应受体被回顾性纳入.分析采购相关伤害发生率及潜在危险因素。在所有获得的腹部器官中,23%的人出现采购相关伤害,丢弃率为4.0%。在肾脏和肝脏中,23%的移植物有采购相关的伤害,2.5%和4%的与采购相关的伤害器官被丢弃,分别。在胰腺采购中,这是27%,丢弃率为24%。男性供体性别和供体BMI>25是所有三个腹部器官采购相关损伤的显著危险因素,而异常血管形成仅对肾脏和肝脏有意义。在多变量Cox回归分析中,采购相关损伤不是移植物衰竭的显著预测因子(肾脏;HR0.99,95%CI0.75-1.33,p=0.99,肝脏;HR0.92,95%CI0.66-1.28,p=0.61,胰腺:HR1.16;95%CI0.16-8.68,p=0.88).这项研究的结果表明,移植外科医生在确定与采购相关的伤害的可接受性和可修复性方面表现出良好的决策能力。
    In this study, 10 years of procurement quality monitoring data were analyzed to identify potential risk factors associated with procurement-related injury and their association with long-term graft survival. All deceased kidney, liver, and pancreas donors from 2012 to 2022 and their corresponding recipients in the Netherlands were retrospectively included. The incidence of procurement-related injuries and potential risk factors were analyzed. Of all abdominal organs procured, 23% exhibited procurement-related injuries, with a discard rate of 4.0%. In kidneys and livers, 23% of the grafts had procurement-related injury, with 2.5% and 4% of organs with procurement-related injury being discarded, respectively. In pancreas procurement, this was 27%, with a discard rate of 24%. Male donor gender and donor BMI >25 were significant risk factors for procurement-related injury in all three abdominal organs, whereas aberrant vascularization was significant only for the kidney and liver. In the multivariable Cox regression analyses, procurement-related injury was not a significant predictor for graft failure (kidney; HR 0.99, 95% CI 0.75-1.33, p = 0.99, liver; HR 0.92, 95% CI 0.66-1.28, p = 0.61, pancreas: HR 1.16; 95% CI 0.16-8.68, p = 0.88). The findings of this study suggest that transplant surgeons exhibited good decision-making skills in determining the acceptability and repairability of procurement-related injuries.

    家庭住院代表了传统住院的替代方案,为血液学患者提供可比的临床安全性。家庭治疗可以从静脉注射抗生素到更复杂的情况,如造血干细胞移植和嵌合抗原受体T细胞治疗后早期的护理。从常规住院早期出院是可行的,并有助于减少医院资源和等待名单。多学科小组的协调努力,包括血液学家,护士,药剂师,确保患者的安全和护理的连续性。传统的家庭住院模式依赖于家访和与医生和护士的电话咨询。然而,使用电子健康技术,比如MY-Meedura,可以加强沟通和监控,从而改善患者的治疗效果,无需额外费用。临床药师积极参与家庭住院计划至关重要,不仅为了药物的适当后勤管理,而且为了确保其适当性,优化治疗,来自团队和患者的地址查询,促进坚持。总之,实施造血干细胞移植和嵌合抗原受体T细胞治疗家庭住院计划,使用电子健康工具和多学科护理模式,可以优化患者护理并提高生活质量,而不会增加医疗保健成本。
    Home hospitalization represents an alternative to traditional hospitalization, providing comparable clinical safety for hematological patients. At-home therapies can range from the delivery of intravenous antibiotics to more complex scenarios, such as the care during the early period after hematopoietic stem cell transplantation and chimeric antigen receptor T-cell therapy. Early discharge from conventional hospitalization is feasible and helps reduce hospital resources and waiting lists. The coordinated efforts of multidisciplinary teams, including hematologists, nurses, and pharmacists, ensure patient safety and continuity of care. The traditional model of home hospitalization relies on home visits and telephone consultations with physicians and nurses. However, the use of eHealth technologies, such as MY-Medula, can enhance communication and monitoring, and thereby improve patient outcomes with no additional costs. The active involvement of a clinical pharmacist in home hospitalization programs is essential, not only for the proper logistical management of the medication but also to ensure its appropriateness, optimize treatment, address queries from the team and patients, and promote adherence. In conclusion, the implementation of hematopoietic stem cell transplantation and chimeric antigen receptor T-cell therapy home hospitalization programs that use both an eHealth tool and a multidisciplinary care model can optimize patient care and improve quality of life without increasing healthcare costs.

    该病例描述了胫骨近端自体移植收获的罕见并发症,并强调了术前代谢检查和骨骼健康优化的重要性。证据等级:IV。
    UNASSIGNED: A 60-year-old female underwent proximal tibial autograft harvest for a Cotton osteotomy. Her postoperative course was complicated by psychogenic non-epileptic seizure (PNES) episodes leading to unintentional weightbearing. Knee radiographs at 6 weeks post-procedure demonstrated a displaced proximal tibia fracture through the autograft harvest site. Further clinical review revealed metabolic derangements consistent with secondary hyperparathyroidism. Initial nonoperative treatment led to atrophic varus nonunion requiring definitive treatment with total knee arthroplasty with revision components.
    UNASSIGNED: This case describes a rare complication of proximal tibial autograft harvest and highlights the importance of preoperative metabolic workup and bone health optimization.Level of Evidence: IV.

    肾移植后不坚持免疫抑制药物是移植物排斥和丢失的重要原因。最小化不依从性的方法集中在识别药物不依从性的发作。但是到那时,对移植物的无法弥补的伤害可能已经发生了,更有效的方法是对可能难以坚持药物治疗的患者采取预防措施。本研究方案的目的是开发和验证用于评估的临床问卷,在移植前的肾移植候选患者中,不坚持免疫抑制药物的倾向。在这个多中心,前瞻性研究,一份巴西葡萄牙语的试点问卷,由Likert缩放的陈述组成,表达患者的信念,关于服药的行为和障碍将从文献综述中收集,来自焦点小组,和一个专家小组。试点问卷将在肾移植等待名单中对至少300名患者进行管理,探索性因素分析将用于制定最终问卷。至少60名患者的随机子样本将在一个月后重新施用量表,以评估测试-重测可靠性。一个多中心,外部验证研究将包括364名肾移植候选人,他们将在手术前和移植后3、6和12个月进行评估,以评估并发有效性,通过与两个评估药物不依从性的量表进行比较,并使用三角法评估药物不依从性来确定预测有效性。将使用结构方程模型通过验证性因子分析评估结构有效性。跨文化的普遍性和有效性将通过多中心研究进行评估,其中将对来自不同文化的肾移植候选患者进行量表到另一种语言的翻译,选择一个子样本进行重测。这项研究将在西班牙进行与规模的西班牙语翻译。
    Non-adherence to immunosuppressive medication after kidney transplant is an important cause of graft rejection and loss. Approaches to minimization of non-adherence have focused on the identification of episodes of medication non-adherence, but by then irreparable harm to the graft may already have occurred, and a more effective approach would be to adopt preventive measures in patients who may have difficulty in adhering to medication. The aim of this study protocol is to develop and validate a clinical questionnaire for assessing, in kidney transplant candidate patients in the pre-transplant setting, the predisposition to non-adherence to immunosuppressive medication. In this multicenter, prospective study, a pilot questionnaire in Brazilian Portuguese language, composed of Likert-scaled statements expressing patients\' beliefs, behaviors and barriers regarding medication taking will be assembled from a literature review, from focus groups, and an expert panel. The pilot questionnaire will be administered to a minimum of 300 patients in kidney transplant waiting lists and exploratory factor analysis will be used for development of the definitive questionnaire. A random subsample of a minimum of 60 patients will have the scale re-administered after one month for evaluation of test-retest reliability. A multicenter, external validation study will include 364 kidney transplant candidates who will be evaluated immediately before surgery and at months 3, 6 and 12 post-transplant for assessment of concurrent validity, by comparison with two scales that assess medication non-adherence, and for determination of predictive validity using a triangulation method for assessment of medication non-adherence. Structural validity will be assessed with confirmatory factor analysis using structural equation modeling. Cross-cultural generalizability and validity will be assessed by a multicenter study, in which a translation of the scale to another language will be administered to kidney transplant candidate patients from a different culture, with a subsample being selected for test-retest. This study will be conducted in Spain with a Spanish translation of the scale.

    在这项纵向观测研究中,我们测量了尿葡萄糖浓度,n=22例肾移植受者(KTRs)在基线(BL)开始于SGLT2I的身体成分和体积状态(生物阻抗谱)以及血浆肾素和醛固酮浓度,以及1周和1、3和6个月后。估计的肾小球滤过率(eGFR)在1周后下降-2mL/min/1.73m2(IQR-10-0),此后保持稳定。1周后尿葡萄糖浓度为10(3-24)g/g肌酐,与eGFR相关(r2=0.273;p=0.057)。SGLT2I不影响HbA1c,空腹血糖,体重,脂肪或瘦体重。SGLT2I减少液体超负荷取决于基线过度水合(OH,r2=0.54,p=0.0003)没有发生脱水。血浆醛固酮在第7天增加,而血浆肾素没有显着变化。总之,SGLT2I校正了基线时过度水合升高患者的液体超负荷,而在等容的KTRs液体状态保持稳定,而体内水分没有减少到参考范围以下,从而提高肾移植后患者SGLT2I治疗的安全性。糖尿,SGLT2I对血糖控制和体重的影响,在依赖于eGFR的KTRs中减弱。
    In this longitudinal observational study, we measured urinary glucose concentration, body composition and volume status (bioimpedance spectroscopy) and plasma renin and aldosterone concentrations in n = 22 kidney transplant recipients (KTRs) initiating on SGLT2I at baseline (BL), and after 1 week and 1, 3, and 6 months. Estimated glomerular filtration rate (eGFR) decreased by -2 mL/min/1.73 m2 (IQR -10-0) after 1 week and remained stable thereafter. Urinary glucose concentration was 10 (3-24) g/g creatinine after 1 week and correlated with eGFR (r2 = 0.273; p = 0.057). SGLT2I did not affect HbA1c, fasting blood glucose, body weight, fat or lean mass. SGLT2I decreased fluid overload dependent on baseline overhydration (OH, r2 = 0.54, p = 0.0003) without occurrence of dehydration. Plasma aldosterone increased at day 7, while plasma renin did not change significantly. In conclusion, SGLT2I corrected fluid overload in patients with elevated overhydration at baseline, while in euvolemic KTRs fluid status remained stable without reduction of body water below the reference range, thus promoting the safety of SGLT2I therapy in patients following kidney transplantation. Glucosuria, together with effects of SGLT2I on blood glucose control and body weight, is attenuated in KTRs dependent on eGFR.
