The clinician’s view of digital data management in the medical laboratory is undoubtedly more important for quality and patient safety than that of the laboratory itself. This is clear from international standards: European standards such as the International Patient Summary (IPS) and the Pharmacotherapy Decision Support System (CEN ISO/TS 22756:2020), alongside numerous international standards. The relevant ISO document families originated in the 1980s. The ISO Open Systems Interconnection (ISO-OSI) model is the basis for the standards on system interconnection. Attention was then directed to the functional content of interconnections, i.e. interoperability. ISO has provided standards for interoperability in various fields, such as drugs and various objects. CLSI recently published the document AUTO17, dedicated to semantic interoperability for in vitro diagnostic systems.
临床医生对医学实验室数字化数据管理的看法无疑比实验室本身对质量和患者安全更重要。从国际标准中可以清楚地看出这一点:欧洲标准,如国际患者摘要(IPS)和药物治疗决策支持系统(CEN ISO/TS 22756:2020),以及许多国际标准。相关的ISO文件族起源于20世纪80年代。ISO开放系统互连(ISO- osi)模型是系统互连标准的基础。然后将注意力转向互连的功能内容,即互操作性。ISO提供了各种领域的互操作性标准,例如药品和各种对象。CLSI最近发布了AUTO17文件,致力于体外诊断系统的语义互操作性。

The medical world is involved in the urgency of the ecological transition also from a regulatory and certification point of view. For Laboratory Medicine, the topic of environmental sustainability was addressed in Europe by European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) in the 2022 Third Strategic Conference. Its Green and Sustainable Laboratories Task Force also published a Booklet with recommendations for chemicals, energy, water, and waste. There are many theoretical and practical suggestions, often aimed at the construction of new SMART and GREEN laboratories and involving many stakeholders. However, there are preliminary actions for sustainability that can be pursued immediately by all laboratories: dematerialization with the interoperability of Information and Communication Technology (ICT) systems; risk management and quality assurance through ISO 15189 accreditation and the application of Total Quality Management (TQM); efficiency and the hunt for waste with the application of the LEAN vision to laboratories. Awareness of the practicability of interventions should be supported by adequate educational activities.
从监管和认证的角度来看,医学界也参与了生态转型的紧迫性。对于检验医学,欧洲临床化学和检验医学联合会(EFLM)在2022年第三次战略会议上讨论了环境可持续性的主题。它的绿色和可持续实验室工作组还出版了一本小册子,对化学品、能源、水和废物提出了建议。有许多理论和实践建议,往往是针对新的SMART和绿色实验室的建设,并涉及许多利益相关者。但是,所有实验室都可以立即采取可持续性的初步行动:利用信息和通信技术系统的互操作性实现非物质化;通过ISO 15189认证和全面质量管理(TQM)的应用进行风险管理和质量保证;将精益生产理念应用于实验室,提高效率,减少浪费。应当通过适当的教育活动来支持对干预措施的实用性的认识。

La senescenza nel microambiente tumorale 肿瘤微环境中的衰老
Q3 Health Professions Pub Date : 2023-10-01 DOI: 10.23736/s1825-859x.23.00206-2

Senescence is a complex biological process of gradual deterioration of cellular function over time in which cells stop dividing and have reduced functionality. In fact, senescent cells remain in a state of non-reactive cell cycle arrest although they preserve a metabolically active capacity of altering genetic and phenotypic characteristics as well as influencing the surrounding environment and adjacent cells. They are characterized by increased lysosomal activity and the acquisition of a bioactive secretome known as the senescence-associated secretory phenotype (SASP). The SASP phenotype consists of a variety of molecules, including, proinflammatory cytokines (IL-6, IL-8) chemokines, growth factors, angiogenic factors, proteases, extracellular matrix components, and metalloproteinases. The role of SASP in the tumor context is ambivalent because it seems that it protects cells from a pathological condition but also it contains a set of factors capable of inducing a neoplastic transformation. Cancer cells, in fact, can evade cell cycle control mechanisms, take advantage of senescence in order to survive and continue to proliferate, thus contributing to cancer progression. Furthermore, SASP can attract cells of the immune system to the site of senescence and T cells, indeed, assume a crucial role in the tumor microenvironment, supporting a delicate balance between immune response and promotion of tumor growth. Understanding these processes may provide new opportunities for the development of therapies that enhance the immune response against cancer and improve health in aging.
衰老是一个复杂的生物学过程,随着时间的推移,细胞功能逐渐退化,细胞停止分裂,功能下降。事实上,衰老细胞仍处于非反应性细胞周期停滞状态,尽管它们保留了改变遗传和表型特征以及影响周围环境和邻近细胞的代谢活性能力。它们的特征是溶酶体活性增加和获得生物活性分泌组,称为衰老相关分泌表型(SASP)。SASP表型由多种分子组成,包括促炎细胞因子(IL-6、IL-8)趋化因子、生长因子、血管生成因子、蛋白酶、细胞外基质成分和金属蛋白酶。SASP在肿瘤中的作用是矛盾的,因为它似乎保护细胞免受病理状态,但它也包含一系列能够诱导肿瘤转化的因素。事实上,癌细胞可以逃避细胞周期控制机制,利用衰老来生存和继续增殖,从而促进癌症的进展。此外,SASP可以将免疫系统的细胞吸引到衰老部位,T细胞在肿瘤微环境中起着至关重要的作用,支持免疫反应和促进肿瘤生长之间的微妙平衡。了解这些过程可能为开发增强抗癌免疫反应和改善衰老健康的治疗方法提供新的机会。

BACKGROUND: Cytometric analysis of liquids can be performed in automation and microscopy. The aim of this work was to highlight when the instrumental and microscopic cellular evaluation of peritoneal fluid could be useful for the diagnosis and therapy.METHODS: The automated analysis was performed on an EDTA test tube sample, using the Body Fluid application of Yumizen 2500 (Horiba, Kyoto, Japan) which counted total leukocytes (BF-WBC), red blood cells (BF-RBC), polymorphonuclear cells (BF-PN) and mononuclear cells (BF-MN). The microscopic analysis was carried out on May-Grünwald Giemsa smears set up and was colored using Yumizen SPS, after centrifugation of the sample at 2000 rpm for 5 minutes.RESULTS: We selected four cases of leukocyte counts on peritoneal fluid. Case 1: 403 leukocytes/μL with 66% PN and 34% MN, under the microscope 52% PN and 48% MN of which 20% lymphocytes, 28% cells with nucleocytoplasmic ratio in favor of cytoplasm, probably of mesothelial origin. Case 2: 1017 leukocytes with 5% PN and 95% MN, under the microscope 3% PN and 97% MN of which 67% lymphocytes, 30% cells surrounded by lymphocytes. Case 3: 4129 leukocytes with 26% PN and 74% MN, under the microscope 1% PN and 99% MN, of which 9% lymphocytes and 90% voluminous mononuclear cells with nucleocytoplasmic ratio in favor of the nucleus, nucleolate, chromatin in large plates and basophilic and vacuolate cytoplasm. Case 4: 69 leukocytes differentiated into PN 4% and MN 96%, differential evaluation was not executable on microscopy due to the scarcity of the elements available.CONCLUSIONS: An algorithm was developed to standardize the diagnostic pathway on the peritoneal fluid: in the case of a cell count <100 we reported only the absolute value of the determined elements; for counts with elements ≥100 we reported the absolute value with the instrumental differentiation in PN and MN expressed in terms of percentage and note relating to the interference on MN of mononuclear elements of probable mesothelial origin; we performed the smear to confirm instrumental data and communicate microscopic evaluation to clinician. Case 4 showed how <100 cellular elements were too few for an effective microscopic evaluation. In our opinion a cut-off of 100 may be the most appropriate number to perform a differential cell evaluation useful to the diagnostic path; however, additional verification is necessary on a more significant number of cases. We also believe that this algorithm can be applied to other fluids except cerebral spinal fluid.
背景:液体的细胞分析可以在自动化和显微镜下进行。这项工作的目的是强调当仪器和显微细胞评价腹膜液可用于诊断和治疗。方法:对EDTA试管样品进行自动分析,使用Yumizen 2500体液应用程序(日本京都,Horiba),计数总白细胞(BF-WBC),红细胞(BF-RBC),多形核细胞(BF-PN)和单个核细胞(BF-MN)。样品在2000 rpm下离心5分钟后,显微镜分析建立的may - gr nwald Giemsa涂片,并使用Yumizen SPS染色。结果:我们选择了4例腹膜液白细胞计数。病例1:403个白细胞/μL, PN为66%,MN为34%,显微镜下PN为52%,MN为48%,其中淋巴细胞占20%,细胞质占28%,可能来源于间皮细胞。病例2:1017个白细胞,5% PN, 95% MN,显微镜下3% PN, 97% MN,其中67%淋巴细胞,30%细胞被淋巴细胞包围。病例3:4129个白细胞,PN为26%,MN为74%,显微镜下PN为1%,MN为99%,其中淋巴细胞9%,体积单核细胞90%,核质比有利于细胞核、核仁、大板染色质和嗜碱性和液泡细胞质。病例4:69个白细胞分化为4%的PN和96%的MN,由于缺乏可用的元素,在显微镜下无法进行鉴别评估。结论:开发了一种算法来标准化腹膜液的诊断途径:在细胞计数<100的情况下,我们只报告测定元素的绝对值;对于元素≥100的计数,我们报告了PN和MN的仪器分化的绝对值,以百分比表示,并注意到可能起源于间皮细胞的单个核元素对MN的干扰;我们进行了涂片以确认仪器数据并向临床医生传达显微镜评估。病例4显示<100个细胞元素太少,无法进行有效的显微镜评估。在我们看来,截断100可能是执行对诊断路径有用的鉴别细胞评估的最合适的数字;但是,需要对数目更大的案件进行进一步核查。我们还认为,该算法可以应用于脑脊液以外的其他液体。

Case 4: 69 leukocytes differentiated into PN 4% and MN 96%, differential evaluation was not executable on microscopy due to the scarcity of the elements available.CONCLUSIONS: An algorithm was developed to standardize the diagnostic pathway on the peritoneal fluid: in the case of a cell count <100 we reported only the absolute value of the determined elements; for counts with elements ≥100 we reported the absolute value with the instrumental differentiation in PN and MN expressed in terms of percentage and note relating to the interference on MN of mononuclear elements of probable mesothelial origin; we performed the smear to confirm instrumental data and communicate microscopic evaluation to clinician. Case 4 showed how <100 cellular elements were too few for an effective microscopic evaluation. In our opinion a cut-off of 100 may be the most appropriate number to perform a differential cell evaluation useful to the diagnostic path; however, additional verification is necessary on a more significant number of cases. We also believe that this algorithm can be applied to other fluids except cerebral spinal fluid.","PeriodicalId":35363,"journal":{"name":"Rivista Italiana della Medicina di Laboratorio","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135349036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
