    Titelübersetzung Proyecto colaborativo internacional donante.
    Abstract The International Donor Collaborative Project (PCID) research group was created in 1996 in Spain with the aim of promoting research in the field of organ donation and transplantation, led by Spanish surgeons. During this period they have developed the questionnaires of the PCID, both the attitude towards cadaver and live donation, which are the most used questionnaires in publications in indexed journals. They have been the driving group of stratified studies representative of the populations under study, and of the performance of multivariate statistical analyzes in the field of psycho-social research in organ donation and transplantation. The main contributions of the group focus on the analysis of health center professionals and emerging migrant groups. In recent years, studies have been extended to the United States, Latin America (mainly Mexico) and Europe.

    Abstract Background: Liver transplantation (LT) is crucial for end-stage liver disease patients, but organ shortages persist. Donation after circulatory death (DCD) aims to broaden the donor pool but presents challenges. Complications like acute rejection, hepatic artery thrombosis, and biliary issues still impact posttransplant prognosis. Biomarkers, including extracellular vesicles (EVs) and microRNAs (miRNAs), show promise in understanding and monitoring posttransplant events. This study explores the role of EVs and their miRNA cargo in LT, including their potential as diagnostic tools.
    Methods: EVs from intrahepatic end-ischemic organ preservation solution (eiOPS) in 79 donated livers were detected using different techniques (nanosight tracking analysis, transmission electron microscopy, and flow cytometry). EV-derived miRNAs were identified by quantitative real time-polymerase chain reaction. Bioinformatics analysis was performed using the R platform.
    Results: Different-sized and origin-specific EVs were found in eiOPS, with significantly higher concentrations in DCD compared with donation after brain death organs. Additionally, several EV-associated miRNAs, including let-7d-5p, miR-28-5p, miR-200a-3p, miR-200b-3p, miR-200c-3p, and miR-429, were overexpressed in DCD-derived eiOPS. These miRNAs also exhibited differential expression patterns in liver tissue biopsies. Pathway analysis revealed enrichment in signaling pathways involved in extracellular matrix organization and various cellular processes. Moreover, specific EVs and miRNAs correlated with clinical outcomes, including survival and early allograft dysfunction. A predictive model combining biomarkers and clinical variables showed promise in acute rejection detection after LT.
    Conclusions: These findings provide new insights into the use of EVs and miRNAs as biomarkers and their possible influence on posttransplantation outcomes, potentially contributing to improved diagnostic approaches and personalized treatment strategies in LT.

    Abstract DAMPs (danger-associated molecular patterns) are self-molecules of the organism that appear after damage. The endothelium plays several roles in organ rejection, such as presenting alloantigens to T cells and contributing to the development of inflammation and thrombosis. This study aimed to assess whether DAMPs present in the organ preservation solution (OPS) after cold ischemic storage (CIS) contribute to exacerbating the endothelial response to an inflammatory challenge and whether defibrotide treatment could counteract this effect. The activation of cultured human umbilical vein endothelial cells (HUVECs) was analyzed after challenging with end-ischemic OPS (eiOPS) obtained after CIS. Additionally, transwell assays were performed to study the ability of eiOPS to attract lymphocytes across the endothelium. The study revealed that eiOPS upregulated the expression of MCP-1 and IL-6 in HUVECs. Moreover, eiOPS increased the membrane expression of ICAM-1and HLA-DR, which facilitated leukocyte migration toward a chemokine gradient. Furthermore, eiOPS demonstrated its chemoattractant ability. This activation was mediated by free mitochondria. Defibrotide was found to partially inhibit the eiOPS-mediated activation. Moreover, the eiOPS-mediated activation of endothelial cells (ECs) correlated with early allograft dysfunction in liver transplant patients. Our finding provide support for the hypothesis that mitochondria released during cold ischemia could trigger EC activation, leading to complications in graft outcomes. Therefore, the analysis and quantification of free mitochondria in the eiOPS samples obtained after CIS could provide a predictive value for monitoring the progression of transplantation. Moreover, defibrotide emerges as a promising therapeutic agent to mitigate the damage induced by ischemia in donated organs.

    Abstract Background: Innate immunity plays a fundamental role in solid organ transplantation. Myeloid cells can sense danger signals or DAMPs released after tissue or cell damage, such as during ischemia processes. This study aimed to identify DAMPs released during cold ischemia storage of human liver and analyze their ability to activate the inflammasome in myeloid cells and the possible implications in terms of short-term outcomes of liver transplantation.
    Methods: 79 samples of organ preservation solution (OPS) from 79 deceased donors were collected after cold static storage. We used different analytical methods to measure DAMPs in these end-ischemic OPS (eiOPS) samples. We also used eiOPS in the human macrophage THP-1 cell line and primary monocyte cultures to study inflammasome activation.
    Findings: Different DAMPs were identified in eiOPS, several of which induced both priming and activation of the NLRP3 inflammasome in human myeloid cells. Cold ischemia time and donation after circulatory death negatively influenced the DAMP signature. Moreover, the presence of oligomeric inflammasomes and interleukin-18 in eiOPS correlated with early allograft dysfunction in liver transplant patients.
    Interpretation: DAMPs released during cold ischemia storage prime and activate the NLRP3 inflammasome in liver macrophages after transplantation, inducing a pro-inflammatory environment that will complicate the outcome of the graft. The use of pharmacological blockers targeting DAMPs or the NLRP3 inflammasome in liver ischemia during static cold storage or through extracorporeal organ support could be a suitable strategy to increase the success of liver transplantation.

    Titelübersetzung Resultados del tratamiento del microcarcinoma papilar de tiroides adaptado al riesgo de recurrencia.
    Abstract Background: The incidence of papillary thyroid microcarcinoma (PTMC) is increasing.
    Objective: To analyze the long-term prognosis of PTMC.
    Method: Study population: patients with a histopathological diagnosis of PTMC (size ≤ 1 cm) treated according to the risk of recurrence of the Latin American Thyroid Society. Inclusion criteria: minimum follow-up of 2 years, availability of histopathological samples, and treatment compliance. Exclusion criteria: previous thyroid surgery, other synchronous malignancies or ectopic location of the PTMC. Study variables: persistences, recurrences and mortality.
    Results: Based on the risk of recurrence, PTMC has very low risk in 65.2% (n = 105), low risk in 17.4% (n = 28) and high risk in 17.4% (n = 28). In high risk patients, total thyroidectomy was performed in all cases, cervical lymphadenectomy in 57,1% (n = 16) and metabolic therapy with I
    Conclusions: PTMC treated based on its risk of recurrence has a good long-term prognosis, without persistences, with a low number of recurrences and absence of disease-associated mortality.

    Titelübersetzung Actitud y conocimiento sobre donación de órganos de estudiantes de medicina de una universidad pública del noreste de México
    Abstract Objective: To evaluate the knowledge and attitude towards organ donation of medicine students of a Northwestern Mexico public university.
    Materials and methods: A prolective, descriptive, observational, and cross-sectional study. A 34 items cross-sectional survey evaluating knowledge and attitude towards organ donation in 3,056 medicine students during 2013-2015. Descriptive statistics were used as absolute frequencies, percentages, mean and standard deviation, as well as the Chi-square test. A p < 0.05 was considered significant.
    Results: 74% of students would donate their own organs, mainly due to reciprocity (41%). 26% of students would not donate, 48% of them because of fear that their organs could be taken before death. 86% would donate organs from a relative. 64% have spoken about organ donation and transplantation with their family and 67% with friends. 50% said they had received no information about it. 68% understand the concept of brain death.
    Conclusion: Students received little information about organ donation during college. Despite that, most of them showed a positive attitude and are willing to donate.
