    背景:肾脏活体捐赠存在风险,然而,关于肾切除术风险和对候选人的心理影响的标准化信息提供仍然缺乏.
    目的:本研究评估了交互式健康技术在改善肾脏活体捐赠知情同意过程中的益处。
    方法:肾脏中心机构开放门户提供关于肾脏疾病和捐献的全面信息。愿意在赫尔辛基大学医院(2019年1月至2022年1月)开始肾脏活体捐赠过程的个人被邀请使用肾脏中心中包含的患者量身定制的数字护理路径(活体捐赠者数字护理路径)。该平台提供详细的捐赠过程信息,并促进医疗保健专业人员和患者之间的沟通。通过电子健康素养量表(eHEALS)评估电子健康素养,系统可用性量表(SUS)的可用性,和系统效用通过李克特量表调查,得分为1-5分。定性内容分析解决了一个开放式问题。
    结果:肾脏中心门户每月接受8000多次访问,包括其关于捐赠福利(n=1629次)和对捐赠者生活的影响(n=4850次)的部分。在127名活体肾脏捐赠候选人中,7没有使用活人数字护理路径。用户年龄从20岁到79岁不等,他们交换了3500多条信息。共有74名活体捐献者参加了调查。女性候选人更经常在互联网上搜索有关肾脏捐赠的信息(n=79女性候选人,n=48男性候选人;P=.04)。平均eHEALS评分与互联网使用健康决策相关(r=0.45;P<.001)及其重要性(r=0.40;P=.01)。参与者发现,活体捐赠者数字护理路径在技术上令人满意(平均SUS得分为4.4,SD0.54),并且有用,但在捐赠决策中并不重要。关注集中在手术后应对捐助者和接受者。
    结论:远程医疗有效地教育活体肾脏捐献者的捐献过程。活体捐献者数字护理路径是一种有价值的电子健康工具,帮助临床医生规范知情同意的步骤。

    BACKGROUND: Kidney living donation carries risks, yet standardized information provision regarding nephrectomy risks and psychological impacts for candidates remains lacking.
    OBJECTIVE: This study assesses the benefit of interactive health technology in improving the informed consent process for kidney living donation.
    METHODS: The Kidney Hub institutional open portal offers comprehensive information on kidney disease and donation. Individuals willing to start the kidney living donation process at Helsinki University Hospital (January 2019-January 2022) were invited to use the patient-tailored digital care path (Living Donor Digital Care Path) included in the Kidney Hub. This platform provides detailed donation process information and facilitates communication between health care professionals and patients. eHealth literacy was evaluated via the eHealth Literacy Scale (eHEALS), usability with the System Usability Scale (SUS), and system utility through Likert-scale surveys with scores of 1-5. Qualitative content analysis addressed an open-ended question.
    RESULTS: The Kidney Hub portal received over 8000 monthly visits, including to its sections on donation benefits (n=1629 views) and impact on donors\' lives (n=4850 views). Of 127 living kidney donation candidates, 7 did not use Living Donor Digital Care Path. Users\' ages ranged from 20 to 79 years, and they exchanged over 3500 messages. A total of 74 living donor candidates participated in the survey. Female candidates more commonly searched the internet about kidney donation (n=79 female candidates vs n=48 male candidates; P=.04). The mean eHEALS score correlated with internet use for health decisions (r=0.45; P<.001) and its importance (r=0.40; P=.01). Participants found that the Living Donor Digital Care Path was technically satisfactory (mean SUS score 4.4, SD 0.54) and useful but not pivotal in donation decision-making. Concerns focused on postsurgery coping for donors and recipients.
    CONCLUSIONS: Telemedicine effectively educates living kidney donor candidates on the donation process. The Living Donor Digital Care Path serves as a valuable eHealth tool, aiding clinicians in standardizing steps toward informed consent.

    本研究的新颖性和基本目的是使用阴离子表面活性剂(SAA)的临界胶束浓度在水绿色溶剂中制备新型抗炎铁配合物。已经制备了三种新的抗炎铁复合物。噻吩电子给体(D)席夫碱(2-(2-OH-亚苄基)-氨基)-4,5,6,7-四羟基苯并[b]噻吩-3-甲腈)已制备。基于CNH分析确认了所有样品的分子结构,1HNMR和13CNMR光谱。通过使用DFT-B3LYP方法的计算化学进一步证实了席夫碱的分子结构,6-31G(D)基准集。观察和模拟1HNMR,UV-Vis。红外/拉曼光谱证实了D的分子结构。将该席夫碱插入氯化铁(FeCl3)中,得到纯铁电荷转移络合物(CTC)。体外和动力学研究证实Fe-CTC复合物具有(浓度依赖性)有效的抗微生物剂-,良好的抗炎活性。自由基清除活性一氧化二氮(NO。)的Fe(III)CTC归因于几何形状的Fe(III)离子通过官能团(-C]N-O变形为八面体(单斜晶系或三斜晶系单晶),NH2)。元素分析和EDS光谱证实了铁与杂原子之间的强结合(N,S,D分子的O)。
    The novelty and the essential purpose of this research is the preparation of new anti-inflammatory iron complexes in water green solvent using critical micelle concentration of anionic surface active agent (SAA). Three new anti-inflammatory iron complexes have been prepared. Thiophene-electron (es) donor (D) Schiff base (2-(2-OH-benzylidene)-amino)-4, 5, 6, 7-tetrah ydrobenzo[b] thiophene-3-carbonitrile) has been prepared. Molecular structures of all samples were confirmed based on CNH analysis, 1H NMR and 13C NMR spectra. The molecular structure of Schiff base is further confirmed by computational chemistry using the DFT-B3LYP method, 6-31G (d) basis set. Observed and simulated 1H NMR, UV-Vis. IR/Raman spectra confirmed the molecular structure of D. This Schiff base is intercalated to ferric chloride (FeCl3) giving pure iron charge transfer complex (CTCs). In vitro and kinetic studies confirmed Fe-CTC complexes had (concentration-dependent) potent antimicrobial-, good anti-inflammatory activities. Free radical scavenging activity nitrous oxide (NO.) of Fe (III)CTCs is attributed to geometry Fe(III) ions as distorted octahedral (either monoclinic or triclinic single crystals) via functional groups (-C]N-O, NH2). Elemental analysis and EDS spectra confirmed strong binding between iron and hetero atoms (N, S, O) of D molecules.

    目的:评估眼科医生对Türkiye角膜移植和捐赠的兴趣和意见。
    方法:使用Google表格编写了一份在线问卷,该问卷的电子链接通过WhatsApp发送给在Türkiye工作的眼科医生。18个开放式/多项选择题被问及眼科医生的人口统计信息及其对角膜移植和捐赠的看法。通过将数据传输到Excel来分析答案。
    结果:共有195位眼科医生参与了调查。虽然68.6%的人表示他们想捐献角膜,21.1%的人表示他们尚未决定,10.3%的人不想捐献角膜。虽然93.8%的参与者同意在需要的情况下进行角膜移植,5.7%的人表示他们还没有决定,0.5%的人表示他们不会接受角膜移植。愿意捐献角膜的最常见(90.5%)原因是给低视力患者带来希望。最常见的(46.2%)的原因不想捐赠一个人的角膜是不愿意有一个人的身体/眼睛完整性受损。绝大多数(80.8%)的参与者认为Türkiye没有足够的角膜捐赠,这主要是(85.9%)由于文化和/或宗教原因。
    结论:即使在受教育程度高且对角膜移植了解最多的样本中,捐献角膜的意愿可能仍低于预期。因此,有必要减轻对角膜捐赠和移植的不切实际的担忧和偏见。
    OBJECTIVE: To evaluate ophthalmologists\' interest and opinions regarding corneal transplantation and donation in Türkiye.
    METHODS: An online questionnaire was prepared using Google Forms, and the electronic link to this questionnaire was sent via WhatsApp to ophthalmologists working in Türkiye. Eighteen open-ended/multiple-choice questions were asked about ophthalmologists\' demographic information and their opinions regarding corneal transplantation and donation. The answers were analyzed by transferring the data to Excel.
    RESULTS: A total of 195 ophthalmologists participated in the survey. While 68.6% of them stated that they wanted to donate their corneas, 21.1% stated that they were undecided, and 10.3% did not want to donate their corneas. While 93.8% of the participants agreed to have a cornea transplant in case of need, 5.7% of them stated that they were undecided, and 0.5% said that they would not accept a cornea transplant. The most frequent (90.5%) reason for being willing to donate one\'s cornea was to give hope to patients with low vision. The most frequent (46.2%) reason for not wanting to donate one\'s cornea was the unwillingness to have one\'s body/eye integrity impaired. The vast majority (80.8%) of the participants thought that there was not enough corneal donation in Türkiye and that this was mostly (85.9%) due to cultural and/or religious reasons.
    CONCLUSIONS: Even in a sample with a high level of education and the most knowledge about corneal transplantation, the willingness to donate corneas may remain below the expected rates. Therefore, it is necessary to alleviate unrealistic concerns and prejudices about corneal donation and transplantation.

    背景:成为活体捐赠者的决定需要考虑复杂的因素,一系列可以作为临床目标的相互作用的因素,政策,和教育干预。我们的目标是评估财务障碍如何与动机相互作用,其他障碍,以及在此过程中的促进者。
    方法:数据来自评估激励因素的公共调查,障碍,和生活捐赠的促进者。我们使用多变量逻辑回归和共识k均值聚类来评估财务问题与决策过程中其他考虑因素之间的相互作用。
    结果:在1592名受访者中,平均年龄为43岁;74%为女性,14%和6%为西班牙裔和黑人,分别。在就业受访者中(72%),40%的人表示,如果没有工资报销,他们将无法捐赠。对费用和依赖护理挑战的担忧与无法在没有工资补偿的情况下进行捐赠有关(OR=1.2,95%CI=1.0-1.3;OR=1.2,95%CI=1.1-1.3,分别)。确定了四个受访者集群。第1组有强大的激励者和促进者,障碍很小。第2组有与健康问题有关的障碍,紧张,和依赖护理。集群3和集群4有财务障碍。第3组也有与手术和依赖护理相关的焦虑。
    结论:考虑活体器官捐赠时,财务障碍主要与健康和依赖护理问题有关。需要采取有针对性的干预措施,以减少财务障碍并改善提供者关于捐赠相关风险的沟通。
    BACKGROUND: The decision to become a living donor requires consideration of a complex, interactive array of factors that could be targeted for clinical, policy, and educational interventions. Our objective was to assess how financial barriers interact with motivators, other barriers, and facilitators during this process.
    METHODS: Data were obtained from a public survey assessing motivators, barriers, and facilitators of living donation. We used multivariable logistic regression and consensus k-means clustering to assess interactions between financial concerns and other considerations in the decision-making process.
    RESULTS: Among 1592 respondents, the average age was 43; 74% were female and 14% and 6% identified as Hispanic and Black, respectively. Among employed respondents (72%), 40% indicated that they would not be able to donate without lost wage reimbursement. Stronger agreement with worries about expenses and dependent care challenges was associated with not being able to donate without lost wage reimbursement (OR = 1.2, 95% CI = 1.0-1.3; OR = 1.2, 95% CI = 1.1-1.3, respectively). Four respondent clusters were identified. Cluster 1 had strong motivators and facilitators with minimal barriers. Cluster 2 had barriers related to health concerns, nervousness, and dependent care. Clusters 3 and 4 had financial barriers. Cluster 3 also had anxiety related to surgery and dependent care.
    CONCLUSIONS: Financial barriers interact primarily with health and dependent care concerns when considering living organ donation. Targeted interventions to reduce financial barriers and improve provider communication regarding donation-related risks are needed.

    系统性红斑狼疮(SLE)通常被视为死者肾脏捐赠的相对禁忌症。由于肾移植(KT)后免疫环境的变化而引起的病理变化尚不清楚,对肾功能的恢复了解甚少。我们介绍了一例来自SLE已故捐赠者的KT病例,并进行了一年的随访。尽管SLE相关血管瘤在围手术期发展,经介入治疗后治愈。KT后一年进行了预先计划的活检,结果发现狼疮的大部分病理变化和免疫荧光标记物已经消退。肾功能稳定,KT后一年,尿蛋白和潜血水平降低。
    Systemic lupus erythematosus (SLE) is usually regarded as a relative contraindication for deceased kidney donation. The pathological variations because of the changes in the immune environment after kidney transplantation (KT) are unclear, and the recovery of renal function is poorly understood. We present a case of KT from a deceased donor with SLE who was followed-up for one year. Although SLE-related hemangioma developed during the perioperative period, it was cured after interventional treatment. A pre-planned biopsy was performed one year after KT, and it was found that most of the pathological changes and immunofluorescent markers of lupus had resolved. Renal function was stable, and urinary protein and occult blood levels reduced one year after KT.

    背景:许多用于小儿心脏移植(HT)的心脏没有放置。2016年,我们发起了一项质量改进努力,以提高心脏报价接受度。这项研究评估了我们中心这些干预措施的效果。
    方法:实施前/后队列评估(1/1/2008-12/31/2016vs.2017年1月1日-2023年7月1日)比较供体心脏利用率。随着时间的推移,对六种干预措施进行了迭代,以增加要约接受度(“扩展标准”):ABO不相容移植,远距离供体的离体灌注,三维总心脏容积(TCV)评估,接受丙型肝炎或SARS-COV-2感染的供体,和有利于考虑以前认为不可接受的捐赠者的制度文化变革(公共卫生服务风险,心肺复苏持续时间长,等。).研究结果包括年度HT量,候补名单持续时间中位数,验收时的序列号,和移植后的临床结果。
    结果:从1/2008-7/2023年开始,每年的移植量从16/年增加到25/年实施前/实施后。三百十三/389(80%)列出的患者进行了移植。实施后等待时间缩短(P=0.01),使用至少一个扩展标准的接受心脏供血的百分比也是如此(P<0.001)。机构文化变化和TCV评估对供体心脏利用的影响最大(P=0.04和P<0.001)。在HT插管后或心血管重症监护病房(CVICU)天数上无差异(P=0.05-0.9),虽然移植后住院时间增加(P<0.001)。移植后的存活不受使用扩展标准心脏的影响(P=0.3)。
    结论:我们报告了由于纵向,多方面的努力来提高器官的利用率,机构文化变革和TCV评估影响最大。使用延长标准心脏与低生存率无关。
    BACKGROUND: In 2016, we initiated a quality improvement endeavor to increase pediatric heart offer acceptance. This study assessed the effect of these interventions at our center.
    METHODS: We evaluted pre- and postimplementation cohorts (January 1, 2008-December 31, 2016 vs January 1, 2017-July 1, 2023) comparing donor heart utilization. Six interventions were iterated over time to increase offer acceptance (\"extended criteria\"): ABO-incompatible transplant, ex vivo perfusion for distanced donors, 3-dimensional total cardiac volume (TCV) assessment, acceptance of hepatitis-C or Severe Acute Respiratory Syndrome Coronavirus 2 infected donors, and institutional culture change favoring consideration of donors previously considered unacceptable. Outcomes studied included annual HT volume, median waitlist duration, sequence number at acceptance, and post-transplant clinical outcomes.
    RESULTS: During the study period, annual transplant volume increased from 16/year to 25/year pre- and postimplementation. Three hundred thirteen of 389 (80%) listed patients were transplanted. Waitlist duration shortened postimplementation (p = 0.01), as did the percentage of accepted heart offers utilizing at least 1 extended criterion (p < 0.001). Institutional culture change and TCV assessment had the largest impact on donor heart utilization (p = 0.04 and p < 0.001). There was no difference in post-HT intubation or intensive care unit days (p = 0.05-0.9), though post-transplant hospitalization duration (p < 0.001) increased. Post-transplant survival was unaffected by the use of extended criteria hearts (p = 0.3).
    CONCLUSIONS: We report a successful longitudinal, multifaceted effort to increase organ offer utilization, with institutional culture change and TCV assessments most impactful. The use of extended criteria hearts was not associated with inferior survival.

    目的:为了评估供体配子的利用率,患者满意度,和使用供体配子进行治疗的患者的生育治疗结果,根据配子供体的期望种族和种族进行分层。
    方法:调查研究对象:计划在2015年至2020年间在美国东南部的一家学术生育诊所使用供体精子和/或供体卵母细胞进行治疗的患者。
    无主要结果指标:供体配子的利用率,对供体配子选择和生育治疗结果的满意度按患者的种族和种族分层,以及他们的配子捐赠者。
    结果:四百五十名患者符合纳入条件,有170名(38%)对调查做出了回应。在受访者中,59%希望非西班牙裔白配子供体,20%希望非西班牙裔黑配子供体。与寻求非西班牙裔白人配子供体的个体相比,寻求非西班牙裔黑人配子供体的患者使用供体配子的几率较低(OR=0.13,95%CI0.04-0.40)。在评估对供体配子选择的满意度时,寻求非西班牙裔黑人配子供体的患者报告的满意度低于寻求非西班牙裔白人配子供体的患者(OR0.19,95%CI[0.09-0.43]).在评估生育结果时,与非西班牙裔白人患者(OR=0.18,95%CI0.07-0.46)和寻求非西班牙裔白人配子供体的个体相比,非西班牙裔黑人患者和使用非西班牙裔黑人配子供体的成功受孕几率较低。(OR=0.26,95%CI0.09-0.75),分别。
    结论:寻求非西班牙裔黑人供体配子的患者利用率较低,对配子供体选择的满意度较低,与寻求非西班牙裔白人配子捐赠者的人相比,受孕几率较低。这些发现强调了捐助者配子银行内部需要更多的种族多样性,以及通过机构和生育诊所提供的捐助者池中。
    OBJECTIVE: To evaluate donor gamete utilization, patient satisfaction, and fertility treatment outcomes of patients pursuing treatment with donor gametes stratified by the desired race and ethnicity of the gamete donor.
    METHODS: Survey study SUBJECTS: Patients planning to undergo treatment using donor sperm and/or donor oocytes at a single academic fertility clinic in the Southeastern United States between 2015 and 2020.
    UNASSIGNED: None MAIN OUTCOME MEASURES: Utilization rates of donor gametes, satisfaction with donor gamete selection and fertility treatment outcomes stratified by race and ethnicity of patient, as well as that of their gamete donor.
    RESULTS: Four hundred fifty patients were eligible for inclusion and 170 (38%) responded to the survey. Amongst the respondents, 59% desired a non-Hispanic White gamete donor and 20% desired a non-Hispanic Black gamete donor. Patients seeking a non-Hispanic Black gamete donor had lower odds of utilizing donor gametes (OR = 0.13, 95% CI 0.04 - 0.40) compared to individuals seeking a non-Hispanic White gamete donor. When evaluating satisfaction with donor gamete selection, patients seeking a non-Hispanic Black gamete donor reported lower satisfaction compared to individuals seeking a non-Hispanic White gamete donor (OR 0.19, 95% CI [0.09-0.43]). When evaluating fertility outcomes, Non-Hispanic Black patients and those utilizing non-Hispaninc Black gamete donors were found to have a lower odds of successful conception compared to non-Hispanic White patients (OR=0.18, 95% CI 0.07-0.46) and individuals seeking non-Hispanic White gamete donors (OR=0.26, 95% CI 0.09-0.75), respectively.
    CONCLUSIONS: Patients seeking non-Hispanic Black donor gametes have lower utilization rates, less satisfaction with gamete donor selection, and lower odds of conception when compared to those seeking non-Hispanic White gamete donors. These findings highlight the need for more racial diversity within donor gamete banks, as well as within the donor pools available through agencies and fertility clinics.

    全球大流行导致了人群中SARS-CoV-2感染的普遍发生。在后大流行时代,必须了解供体SARS-CoV-2感染对异基因造血干细胞移植(allo-HSCT)后结局的影响。我们回顾性分析了来自轻度SARS-CoV-2感染或早期恢复期(ERS)(第1组,n=65)和晚期恢复期(第2组,n=120)的供体的allo-HSCT。此外,我们将来自先前没有SARS-CoV-2感染的供体的allo-HSCT作为第0组(n=194)。来自具有不同SARS-CoV-2感染状态的供体的移植具有可比的初次植入和存活率。然而,第1组急性移植物抗宿主病(aGvHD)的发生率较高,II-IV级(41.5%与第0组28.1%[p=0.014]和第2组30.6%[p=0.067])和III-IV级(22.2%vs.0组中为9.6%[p=0.004],2组中为12.2%[p=0.049])。相反,第2组的aGvHD风险与第0组相似(p>0.5).多变量分析确定了与II-IV级(风险比[HR]2.307,p=0.010)和III-IV级(HR2.962,p=0.001)aGvHD相关的第1组,没有显著的生存风险因素。总之,我们初步证明了处于活跃感染状态或轻度SARS-CoV-2感染ERS的供体与相关供体移植中aGvHD的发生率较高相关。
    The global pandemic has resulted in the common occurrence of SARS-CoV-2 infection in the population. In the post-pandemic era, it is imperative to understand the influence of donor SARS-CoV-2 infection on outcomes after allogeneic haematopoietic stem cell transplantation (allo-HSCT). We retrospectively analysed allo-HSCTs from donors with mild SARS-CoV-2 infection or early recovery stage (ERS) (group 1, n = 65) and late recovery stage (group 2, n = 120). Additionally, we included allo-HSCT from donors without prior SARS-CoV-2 infection as group 0 (n = 194). Transplants from donors with different SARS-CoV-2 infection status had comparable primary engraftment and survival rates. However, group 1 had higher incidences of acute graft-versus-host disease (aGvHD), grade II-IV (41.5% vs. 28.1% in group 0 [p = 0.014] and 30.6% in group 2 [p = 0.067]) and grade III-IV (22.2% vs. 9.6% [p = 0.004] in group 0 and 12.2% in group 2 [p = 0.049]). Conversely, the risk of aGvHD in group 2 was similar to that in group 0 (p > 0.5). Multivariable analysis identified group 1 associated with grade II-IV (hazard ratio [HR] 2.307, p = 0.010) and grade III-IV (HR 2.962, p = 0.001) aGvHD, which yielded no significant risk factors for survival. In conclusion, we preliminarily demonstrated donors in the active infection state or ERS of mild SARS-CoV-2 infection were associated with higher incidences of aGvHD in transplants from related donors.

    背景:更好地获得直接作用抗病毒(DAA)治疗已经扩大了丙型肝炎病毒(HCV)核酸检测(NAT)阳性器官的利用,具有出色的结果。然而,DAA治疗与乙型肝炎病毒(HBV)再激活有关。
    目的:为了确定利用HBV核心抗体阳性(HBcAb+)和HCVNAT阳性(HCV+)器官的HBV传播或再激活的风险,这可能需要DAA治疗。
    方法:从器官获取和移植网络(OPTN)数据库中获得具有HCVNAT状态的HBcAb+供体的数量。从OPTN特设疾病传播咨询委员会数据库中获得了从移植器官裁定为“已证明”或“可能”传播的意外HBV感染的数量。对“已证实”或“可能”病例的捐赠者进行了图表审查。
    结果:从2016年1月1日至2021年12月31日,从3767个HBcAb+供体中采购了7735个器官,并移植到7469个受体中;545个(14.5%)供体也是HCV+。7名受者发生HBV传播或再激活。HCV+接受者之间的比率没有显着差异(0.18%,2/1115)和HCVNAT阴性(HCV-)器官(0.08%,5/6354)(p=0.28)或在HCV和HCV-肝脏以及非肝脏器官的接受者之间。HBV传播或再激活发生在319的中位数内(范围,41-1117)在失踪的情况下进行移植后的几天,不足,或截断的预防。
    结论:与HBcAb+HCV+器官的DAA治疗相关的HBV再激活比非移植人群报道的频率低。可能是由于在高危移植人群中普遍使用HBV预防。
    BACKGROUND: Better access to direct-acting antiviral (DAA) therapy has broadened the utilization of hepatitis C virus (HCV) nucleic acid testing (NAT) positive organs with excellent outcomes. However, DAA therapy has been associated with hepatitis B virus (HBV) reactivation.
    OBJECTIVE: To determine the risk of HBV transmission or reactivation with utilization of HBV core antibody positive (HBcAb+) and HCV NAT positive (HCV+) organs, which presumably required DAA therapy.
    METHODS: The number of HBcAb+ donors with delineated HCV NAT status was obtained from the Organ Procurement and Transplantation Network (OPTN) database. The number of unexpected HBV infections from transplanted organs adjudicated as \"proven\" or \"probable\" transmission was obtained from the OPTN Ad Hoc Disease Transmission Advisory Committee database. A chart review of the donors of \"proven\" or \"probable\" cases was conducted.
    RESULTS: From January 1, 2016, to December 31, 2021, 7735 organs were procured from 3767 HBcAb+ donors and transplanted into 7469 recipients; 545 (14.5%) donors were also HCV+. HBV transmission or reactivation occurred in seven recipients. The rate is not significantly different between recipients of HCV+ (0.18%, 2/1115) and the HCV NAT negative (HCV-) organs (0.08%, 5/6354) (p = 0.28) or between recipients of HCV+ and HCV- livers as well as non-liver organs. HBV transmission or reactivation occurred within a median of 319 (range, 41-1117) days post-transplant in the setting of missing, inadequate, or truncated prophylaxis.
    CONCLUSIONS: HBV reactivation associated with DAA therapy for HBcAb+ HCV+ organs is less frequent than reported in the non-transplant population, possibly due to the common use of HBV prophylaxis in the at-risk transplant population.

    使用移植后环磷酰胺(Cy后)的单倍体干细胞移植(haplo-SCT)被认为是缺乏匹配供体或由于高风险疾病而迫切需要移植程序的患者的合理治疗选择。我们分析了2018-2023年进行的haplo-SCT的结果。在大多数情况下,中位年龄为52岁的81名患者(46名男性)接受了使用外周血作为干细胞来源的单倍体SCT。适应症包括血液恶性肿瘤(88%的病例为急性白血病)。在25例(31%)中,复发/难治性疾病进行了移植。大多数患者(61%)表现出非常高的疾病风险指数(DRI)。调理方案如下:非清髓性-46例(57%),清髓性-在18(22%)和降低强度-17(20%)。90%的患者移植。所有患者均接受统一的免疫抑制治疗(Cy/TAC/MMF后)。中位随访时间为12个月,急性和慢性GVHD的累积发生率分别为37.5%和37.6%,分别。估计2年总生存率(OS)为43.1%,供体年龄是影响生存率的唯一因素。2年无进展生存率(PFS)为42.5%,而复发率(RI)-35%。非复发死亡率(NRM)的累积发生率为44%,主要是由于感染。Haplo-SCT是血液学患者可行的治疗选择。年轻的捐赠者提高了移植后的存活率。降低感染相关死亡率和复发率的策略仍然是一个挑战。
    Haploidentical stem cell transplantation (haplo-SCT) using post-transplantation cyclophosphamide (post-Cy) is considered a reasonable therapeutic option for patients who lack matched donor or who urgently need transplant procedure due to high risk disease. We analyzed the results of haplo-SCT performed in years 2018-2023. Eighty one patients (46 males) at median age of 52 years underwent haplo-SCT using peripheral blood as a stem cell source in most cases. Indications included hematological malignancies (acute leukemias in 88% of cases). In 25 cases (31%) transplantation was performed in relapsed/refractory disease. Majority of patients (61%) presented with very high and high disease risk index (DRI). Conditioning regimens were as follows: nonmyeloablative - 46 cases (57%), myeloablative - in 18 (22%) and reduced intensity - 17(20%). 90% of patients engrafted. All patients received unified immunosuppressive treatment (post-Cy/TAC/MMF). Median follow-up time was 12 months The cumulative incidence of acute and chronic GVHD was 37.5% and 37.6%, respectively. Estimated 2-year overall survival (OS) was 43.1% and donor\'s age was the only factor influencing survival. The 2-year progression-free survival (PFS) was 42.5%, whereas relapse incidence (RI) - 35%. The cumulative incidence of non-relapse mortality (NRM) was 44% and was mostly due to infections. Haplo-SCT is a feasible treatment option for hematological patients. Younger donor improves post-transplant survival. Strategies to reduce infection-related mortality and relapse rate remain a challenge.
