RESUMO
BACKGROUND AND OBJECTIVES: This article aims to characterize some elements that define the organizational models of healthcare actions in the field of blood and blood products. MATERIALS AND METHODS: This exploratory and qualitative study was carried out based on a documentary survey complemented by interviews with key informants of hemotherapy services from three regional territories in Spain and Brazil. RESULTS: It was evidenced demographic, territorial and organizational characteristics, as well as on instruments, resources and individuals involved in the planning, organization and implementation of services and actions in the area. DISCUSSION: The demographic characteristics and the territorial distribution showed a direct relation with the variation in the blood supply system, in the service structure and in the involvement of different individuals. The predominance of hospital services was a common feature in the territories studied, especially for transfusion services. Regionalization, centralization and concentration strategies were aimed at implementing the organization models of such services and actions in the territories. The use of planning and information technologies presents variation in the territories studied. CONCLUSION: The limits of organizational models are determined by the context and restriction of its constituent elements - structure, resources, financing, individuals involved - which compromise to some degree the objectives/purposes of the policy.
RESUMO
Con el objetivo de elevar los conocimientos acerca de medicina transfusional en profesionales de la salud que cursan el posgrado, se decidió elaborar un producto informático que incluyera los temas correspondientes a la transmisión de infecciones bacterianas por medio de la sangre y las medidas de prevención para lograr una hemoterapia de mayor seguridad. Dicho producto fue desarrollado en la plataforma virtual Chreasoft 3.2, y en él aparecen diferentes módulos que enlazan imágenes y texto, lo cual posibilita una mejor comprensión de la materia y contribuye a motivar el aprendizaje
With the objective of increasing the knowledge about transfusional medicine in postdegree students health professionals, it was decided to elaborate a computer product that included the topics corresponding to the transmission of bacterial infections by means of blood and the preventive measures to achieve a safer hemotherapy. This product was developed in the Chreasoft 3.2 virtual platform, in which different units appear connecting images and text, that facilitates a better understanding of the matter and contributes to motivate the learning

AIM OF THE STUDY: Current knowledge of the molecular basis of most blood groups enables genetic testing for blood groups to overcome the limitations of agglutination. A retrospective review was carried out on genotyping assays performed between 2011 and 2013. METHODS AND PATIENTS: The Molecular Hematology Laboratory of the EFS Alpes-Méditerranée implements commercially available tools (BioArray, Gen-Probe) and other techniques (TaqMan, tetra-primer ARMS-PCR, sequencing). It provides a high-level of expertise in molecular biology, complying with regulatory requirements and standards. RESULTS: A total of 2382 genotyping assays was performed including 764 extended typings and 115 large extended typings essentially in cases involving multiple transfusion and suspected rare blood type. Phenotype discrepancies linked to the RH system accounted for 1501 genotypings. Discrepancies linked to the D and E were mainly related to an allele coding for weak antigen (weak D type 1, 2, 3 and EIV) while those linked to C, c and e antigens were related to an allele coding for a partial antigen (RN, ces(340), ceMo). A high prevalence of (C)ces haplotype in trans of a DAR allele was observed in Afro-Caribbean (54/62). CONCLUSION: In transfusion medicine, red-cell genotyping can overcome the limitations of hemagglutination. It must be used only in situations where it provides a benefit either for the patient or resource management. For implementation of appropriate transfusional practices, this technique requires a sound knowledge of the genetic characteristics of blood groups and clinically relevant variants. It also requires competency with molecular biology tools and continuously updated scientific data.
