    医学会的奖项认可有助于专业发展,职业网络,和学术等级晋升。先前的研究表明,男性是多个医学专业的医学社会奖项的主要接受者;因此,我们试图了解在血库和输血医学(BBTM)医学会中,女性作为获奖者的代表性是否不足.我们检查了血液和生物疗法促进协会(AABB)和美国单采协会的10个总奖项的获得者。对AABB的国家血液基金会名人堂入选者进行了额外评估。性别是通过在线评论代词来确定的,在线照片,和一个基于网络的性别识别应用程序。获奖者的性别由两位作者独立分析和编码,任何差异均由作者协商一致裁定。自1954年以来的330个AABB奖项中,授予男性的奖项要多得多(81.5%,269/330;P<.001)。在自1993年以来颁发的51项美国单采协会奖中,有64.7%(33/51;P=.23)授予了男性。与AABB奖项的前10年(1954-1964年)相比,在最近十年(2010-2021年)中,女性获奖者的比例显着增加(18.5%,5/27vs29.4%,30/102;P<.001)。然而,对现代(2000-2021)的额外时间分析显示,男性获得的AABB奖项明显多于女性(77.4%,144/186vs22.6%,42/186;P<.001)。我们的发现强调了在BBTM中承认女性的历史和当代不平等。没有改进,BBTM获奖者之间的性别均等将需要大约120年的时间(60年中女性获奖者增加了11%);因此,为了确保BBTM领域继续发展,我们必须倡导所有成员之间的公平,包括但不限于性别,种族,和种族。加强公平的战略包括获奖提名人身份的透明度,获奖者,和甄选委员会的个人,获奖者和获奖者的性别比例,以及随着时间的推移跟踪个人人口统计数据的方法的实现。这些战略将允许对获奖候选人性别与获奖人性别的比例进行时间分析,并评估潜在的性别不平等是否会随着时间的推移而改善。
    Award recognition by medical societies contributes to professional development, career networking, and academic rank promotion. Previous research has demonstrated that men are the predominant recipients of medical society awards across multiple medical specialties; as such, we sought to understand whether women are underrepresented as award recipients amongst blood banking and transfusion medicine (BBTM) medical societies. We examined recipients of 10 total awards from the Association for the Advancement of Blood and Biotherapies (AABB) and the American Society for Apheresis. Additional evaluation of AABB\'s National Blood Foundation Hall of Fame inductees was conducted. Gender was determined via online review of pronouns, online photographs, and a web-based gender identification application. Award recipient gender was analyzed and coded independently by two authors, and any discrepancies were adjudicated by author consensus. Of the 330 AABB awards since 1954, significantly more have been conferred to men (81.5%, 269/330; P < .001). Of the 51 American Society for Apheresis awards presented since 1993, 64.7% (33/51; P = .23) have been conferred to men. Compared to the first 10 years of the AABB awards (1954-1964), there has been a significant increase in the proportion of women award recipients in the most recent decade (2010-2021) (18.5%, 5/27 vs 29.4%, 30/102; P < .001). However, additional temporal analysis of the modern era (2000-2021) revealed men have received significantly more AABB awards than women (77.4%, 144/186 vs 22.6%, 42/186; P < .001). Our findings highlight both historic and contemporary inequity for recognition of women within BBTM. Without improvement, gender parity among BBTM award recipients will take approximately 120 years (11% increase in women awardees in 60 years); thus, to ensure the BBTM field continues to progress, we must advocate for equity among all members, including but not limited to gender, race, and ethnicity. Strategies to enhance equity include transparency in the identities of award nominees, award recipients, and individuals on selection committees, the gender ratios of both award nominees and recipients, and implementation of methods for tracking individual demographics over time. These strategies would permit temporal analysis of the ratio of award nominee gender to award recipient gender, and assessment as to whether potential gender inequities improve over time.

    进行了一项研究,以评估和比较黎巴嫩和沙特医疗机构的医学生和居民的输血实践知识。在线调查包括26个问题:4个关于个人数据和输血经验,22个关于献血和捐献者选择领域的输血实践知识,血液成分的生产和储存,选择合适的血液成分,血液成分的给药,输血反应,和并发症。来自沙特阿拉伯的126名学生,84名来自黎巴嫩的学生,来自沙特阿拉伯的31名居民,来自黎巴嫩的23名居民参加了调查。学生和居民的知识水平之间没有显着差异。同样,这两个国家的学生的知识水平没有差异。正确的回答(48%和46%,对于学生和居民来说,分别)低于两组60%的可接受限值。这反映出需要对学生和居民进行更有力和结构良好的教育和培训。
    A study was conducted to assess and compare the knowledge of blood transfusion practices among medical students and residents in Lebanese and Saudi medical institutions. The online survey consisted of 26 questions: 4 about personal data and experience with transfusion and 22 about knowledge on transfusion practices in the areas of blood donation and donor selection, production and storage of blood components, selection of appropriate blood components, administration of blood components, transfusion reactions, and complications. One hundred and twenty-six students from Saudi Arabia, 84 students from Lebanon, 31 residents from Saudi Arabia, and 23 residents from Lebanon participated in the survey. There were no significant differences between students\' and residents\' levels of knowledge. Similarly, there was no difference between the students\' level of knowledge in the two countries. The correct responses (48% and 46%, for students and residents, respectively) were below the acceptable limit of 60% for both groups. This reflects the need for more vigorous and well-structured education and training for both students and residents.

    背景:在文献中,目前尚无关于接受治疗性低温(TH)的缺氧缺血性脑病(HIE)新生儿输血阈值的研究.为了便于准确解释这些新生儿的凝血结果,我们的目标是在这一特定人群中产生特定的参考区间.
    方法:这项回顾性研究纳入了2014年至2022年收治的所有接受TH的HIE新生儿。所有婴儿在TH期间都接受了血液检查,包括凝血曲线。我们的主要结果是评估第三个的估计,第十,25日,50岁,75,第90,入院时(输血前)每个参数的第97百分位数。通过接收机工作特性(ROC)分析,ROC曲线下面积(AUC)和最佳临界点用于评估以国际标准化比值(PT-INR)表示的凝血酶原时间预测任何出血风险的能力.
    结果:本研究共纳入143名婴儿。一入场,纤维蛋白原中值为205mg/dL,凝血酶原时间18.6秒,PT-INR1.50,活化部分凝血活酶时间38.3秒,凝血酶时间18.6秒,抗凝血酶57.0%。预测任何出血风险的PT-INR的最佳临界值大于1.84(AUC.623,p=.024)。
    结论:第一次,我们提出了HIE新生儿队列中凝血参数的百分位数.此外,我们发现PT-INR大于1.84可以显著预测出血风险.需要进一步的研究来确定限制性输血与自由输血方法对于这些高危婴儿是否同样安全。
    BACKGROUND: In the literature, there are no studies about the transfusion threshold for neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). In order to facilitate accurate interpretation of coagulation results in these neonates, we aimed to generate specific reference intervals in this specific population.
    METHODS: This retrospective study included all HIE neonates admitted from 2014 to 2022 to undergo TH. All infants during TH underwent blood exams, including the coagulation profile. Our primary outcome was to assess the estimates of the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles for each parameter on admission (before transfusion). By the receiver operating characteristic (ROC) analysis, the area under the ROC curve (AUC) and the best cut-off point were used to evaluate the ability of the prothrombin time expressed as international normalized ratio (PT-INR) to predict the risk of any bleeding.
    RESULTS: A total of 143 infants were included in this study. On admission, the median fibrinogen value was 205 mg/dL, prothrombin time 18.6 seconds, PT-INR 1.50, activated partial thromboplastin time 38.3 seconds, thrombin time 18.6 seconds, antithrombin 57.0%. The optimal cut-off of PT-INR in predicting the risk of any bleeding was greater than 1.84 (AUC .623, p = .024).
    CONCLUSIONS: For the first time, we proposed the percentiles of coagulation parameters in our cohort of neonates with HIE. Furthermore, we found that a PT-INR greater than 1.84 can significantly predict the risk of any bleeding. Further studies are needed to determine if a restrictive versus a liberal transfusion approach can be equally safer for these high-risk infants.

    镰状细胞病(SCD)是世界上最常见的遗传疾病之一,主要影响经济弱势群体。不断增长的成年SCD人群与可用的SCD诊断和治疗干预措施之间存在显着差异。镰状细胞肝病(SCH)是一个全面的术语,用于描述SCD的急性和慢性肝脏表现。SCH的病理生理学没有明确的模式或序列,这对临床医生和研究人员都构成了挑战。在从诊断到治疗选择的各个层面上,缺乏这种漏报疾病的证据。本文回顾了基本的病理生理学,临床特征,各种SCH表现的生化和放射学发现,并概述了每种情况的管理。SCD的新旧治疗选择,包括羟基脲,红细胞交换输血,熊去氧胆酸,voxelotor,已经审查了l-谷氨酰胺和crizanlizumab,以研究这些选择在治疗SCH中的作用。肝移植的作用,对SCH患者的造血干细胞移植和基因治疗进行了综述.
    Sickle cell disease (SCD) is one of the most common genetic disorders in the world predominantly affecting economically disadvantaged populations. There is a notable discrepancy between the growing adult SCD population and available diagnostic and therapeutic interventions for SCD. Sickle cell hepatopathy (SCH) is an all-inclusive term to describe the acute and chronic liver manifestations of SCD. The pathophysiology of SCH follows no defined pattern or sequence that poses challenges to clinicians and researchers alike. Evidence is lacking for this underreported disease at various levels from diagnostic to therapeutic options. This paper reviews the basic pathophysiology, clinical features, biochemical and radiological findings of various SCH manifestations and outlines the management of each condition. Old and new therapy options in SCD including hydroxyurea, red blood cell exchange transfusion, ursodeoxycholic acid, voxelotor, l-glutamine and crizanlizumab have been reviewed to investigate the role of these options in treating SCH. The role of liver transplant, haematopoietic stem cell transplant and gene therapy in SCH patients have been reviewed.

    目的:冷沉淀抗血友病因子(cryo)已用于积极出血患者的纤维蛋白原替代,纤维蛋白原异常血症,和低纤维蛋白原血症。Cryo在解冻后的保质期为4至6小时,并且在发行产品时需要很长的周转时间,构成其使用的主要限制。最近,美国食品和药物管理局批准病原体减少冷冻沉淀纤维蛋白原复合物(INTERCEPT纤维蛋白原复合物[IFC])用于治疗与纤维蛋白原缺乏相关的出血,它可以在室温下储存,解冻后的保质期为5天。
    方法:我们确定了具有高冷沉淀利用率和废物的位置和特定最终用户。我们与我们的血液供应商合作,在这些地点使用IFC。我们分析了实施前后的浪费和周转时间。
    结果:手术地点的浪费率超过了非手术地点(16.7%对3%),并且是IFC实施的目标。IFC被添加到我们的库存中,以取代成人手术室的所有冷冻订单,这些地方的废物减少到2.2%。所有地点的冷沉淀产物的总废物从8.8%减少到2.4%。冷沉淀产物的周转时间从30.4分钟减少58%至14.6分钟。
    结论:IFC实施后,随着周转时间的延长,废物大幅减少。这改善了血库的后勤,提高患者护理效率,减少昂贵的浪费。
    OBJECTIVE: Cryoprecipitated antihemophilic factor (cryo) has been used for fibrinogen replacement in actively bleeding patients, dysfibrinogenemia, and hypofibrinogenemia. Cryo has a shelf life of 4 to 6 hours after thawing and a long turnaround time in issuing the product, posing a major limitation of its use. Recently, the US Food and Drug Administration approved Pathogen Reduced Cryoprecipitated Fibrinogen Complex (INTERCEPT Fibrinogen Complex [IFC]) for the treatment of bleeding associated with fibrinogen deficiency, which can be stored at room temperature and has a shelf life of 5 days after thawing.
    METHODS: We identified locations and specific end users with high cryoprecipitate utilization and waste. We partnered with our blood supplier to use IFC in these locations. We analyzed waste and turnaround time before and after implementation.
    RESULTS: Operative locations had a waste rate that exceeded nonoperative locations (16.7% vs 3%) and were targeted for IFC implementation. IFC was added to our inventory to replace all cryo orders from adult operating rooms, and waste decreased to 2.2% in these locations. Overall waste of cryoprecipitated products across all locations was reduced from 8.8% to 2.4%. The turnaround time for cryoprecipitated products was reduced by 58% from 30.4 minutes to 14.6 minutes.
    CONCLUSIONS: There has been a substantial decrease in waste with improved turnaround time after IFC implementation. This has improved blood bank logistics, improved efficiency of patient care, and reduced costly waste.

    结果:成功模拟了具有剂量效应的单一抗体和同时存在的两种抗体的抗体鉴定。
    结论:使用RhD血型进行抗体鉴定训练是一种实用而廉价的方法,特别是当阳性样本很短时。
    BACKGROUND: Immunohematology skill education is an important part of the transfusion medicine professional training. We tried to solve the difficulty of obtaining suitable and sufficient positive samples in the immunohematology education.
    METHODS: Different identification panels and panel cells were created by RhD-positive red blood cells (RBCs) and RhD-negative RBCs, according to the underlying antibodies. Diluted anti-D reagent was used as simulated plasma for identification.
    RESULTS: The antibody identification of single antibody with dose-effect and two antibodies present at the same time were successfully simulated.
    CONCLUSIONS: It is a practical and cheap method for antibody identification training to use RhD blood group, especially when positive samples are short.

    Fy3是Duffy(Fy)血型系统的高患病率红细胞抗原。抗Fy3抗体很少见,仅在Duffy无效表型(Fy(a-b-))的个体中出现,这是一种主要发生在非洲人后裔身上的表型。临床上,抗Fy3抗体可引起成人急性和迟发性溶血性输血反应以及胎儿和新生儿的溶血性疾病。这里,我们报告了一个26岁的男性镰状细胞病(SCD)和抗E同种抗体的病史,因血管闭塞危象(VOC)和相关低血红蛋白(Hb)水平入院。对于后者,他接受了一个单位的抗原匹配和交叉匹配相容的包装红细胞(pRBC),没有并发症。十天后,患者再次接受了进一步的VOC和相关的低Hb水平,再次需要红细胞输血。然而,无法鉴定出交叉匹配的pRBC。实验室测试证明了泛反应性,额外的参考测试证明了抗E的存在,抗Fy3和抗Jkb同种抗体。该病例强调了在具有罕见同种免疫特征的SCD患者中与输血相关的诊断和治疗挑战。
    Fy3 is a high-prevalence red blood cell antigen of the Duffy (Fy) blood group system. Anti-Fy3 antibodies are rare and solely arise in individuals with a Duffy null phenotype (Fy(a-b-)), which is a phenotype that mainly occurs in people of African descent. Clinically, anti-Fy3 antibodies can cause both acute and delayed hemolytic transfusion reactions in adults as well as hemolytic disease in fetuses and newborns. Here, we report the case of a 26-year-old male with sickle cell disease (SCD) and a history of anti-E alloantibodies, who was admitted to the hospital with a vaso-occlusive crisis (VOC) and associated low hemoglobin (Hb) level. For the latter he received one unit of antigen-matched and crossmatch-compatible packed red blood cells (pRBCs) without complications. Ten days later the patient was readmitted with a further VOC and associated low Hb level, again requiring a red cell transfusion. However, no crossmatch-compatible pRBCs could be identified. Laboratory testing demonstrated pan-reactivity with additional reference testing demonstrating the presence of anti-E, anti-Fy3 and anti-Jkb alloantibodies. This case highlights the diagnostic and therapeutic challenges associated with blood transfusion in SCD patients with rare alloimmunization profiles.

    这篇综述旨在更好地了解红细胞(RBC)基因分型何时以及为什么适用于输血医学。以系统的方式审查了过去8年在同行评审期刊上发表的文章。红细胞基因分型在输血医学中具有许多应用,包括当不能使用血清学方法时预测患者的抗原谱,比如最近输血的病人,在自身抗体存在的情况下,或没有血清学试剂时。RBC基因分型在产前护理中用于确定接合性并指导Rh免疫球蛋白在孕妇中的施用,以预防胎儿和新生儿的溶血病。在捐赠者测试中,RBC基因分型用于解决ABO/D差异以获得更好的供体保留或用于鉴定对高流行抗原呈阴性的供体,以增加需要稀有血液的患者的血液可用性和相容性。RBC基因分型有助于免疫血液学参考实验室人员进行复杂的抗体检查,建议用于确定患者和预期供体的抗原谱,以准确匹配C,E,和K在多次输血患者中。这种测试还用于确定Rh血型系统中具有变异等位基因的患者或供体。来自此测试助手的信息在复杂抗体鉴定以及来源罕见的等位基因匹配的RBC单位中。虽然红细胞基因分型在输血医学中很有用,其在输血服务中的实施存在局限性,包括测试可用性,周转时间,和成本。
    This review aims to provide a better understanding of when and why red blood cell (RBC) genotyping is applicable in transfusion medicine. Articles published within the last 8 years in peer-reviewed journals were reviewed in a systematic manner. RBC genotyping has many applications in transfusion medicine including predicting a patient\'s antigen profile when serologic methods cannot be used, such as in a recently transfused patient, in the presence of autoantibody, or when serologic reagents are not available. RBC genotyping is used in prenatal care to determine zygosity and guide the administration of Rh immune globulin in pregnant women to prevent hemolytic disease of the fetus and newborn. In donor testing, RBC genotyping is used for resolving ABO/D discrepancies for better donor retention or for identifying donors negative for high-prevalence antigens to increase blood availability and compatibility for patients requiring rare blood. RBC genotyping is helpful to immunohematology reference laboratory staff performing complex antibody workups and is recommended for determining the antigen profiles of patients and prospective donors for accurate matching for C, E, and K in multiply transfused patients. Such testing is also used to determine patients or donors with variant alleles in the Rh blood group system. Information from this testing aides in complex antibody identification as well as sourcing rare allele-matched RBC units. While RBC genotyping is useful in transfusion medicine, there are limitations to its implementation in transfusion services, including test availability, turn-around time, and cost.
