Unmet needs in ß-thalassemia and the evolving treatment landscape.

ß-thalassemias are genetic disorders causing an imbalance in hemoglobin production, leading to varying degrees of anemia, with two clinical phenotypes: transfusion-dependent thalassemia (TDT) and non-transfusion-dependent thalassemia (NTDT). Red blood cell transfusions and iron chelation therapy are the conventional treatment options for the management of ß-thalassemia. Currently available conventional therapies in thalassemia have many challenges and limitations. Accordingly, multiple novel therapeutic approaches are currently being developed for the treatment of ß-thalassemias. These strategies can be classified into three categories based on their efforts to address different aspects of the underlying pathophysiology of ß-thalassemia: correction of the α/ß globin chain imbalance, addressing ineffective erythropoiesis, and targeting iron dysregulation. Managing ß- thalassemia presents challenges due to the many complications that can manifest, limited access and availability of blood products, and lack of compliance/adherence to treatment. Novel therapies targeting ineffective erythropoiesis and thus improving anemia and reducing the need for chronic blood transfusions seem promising. However, the complex nature of the disease itself requires personalized treatment plans for each patient. Collaborations and partnerships between thalassemia centers can also help share knowledge and resources, particularly in regions with higher prevalence and limited resources. This review will explore the different conventional treatment modalities available today for the management of ß-thalassemia, discuss the unmet needs and challenges associated with them in addition to exploring the role of some novel therapeutic agents in the field.

Ethics in transfusion medicine: Are the intricate layers of ethics all universal? A global view.

Ethical principles have been considered, and in several respects regulated, along the entire blood procurement chain from donor motivation to transfusion to the patient. Consent of donors and voluntary non-remunerated donation are fields which have been addressed by codes of ethics and legislation. Caring for donor health is an area of further development of ethical standards. In part, blood products have also become a market, where commercial principles may synergize, but also creating issues in equality and maintaining human dignity that challenge societal solutions. At the bedside, the main global challenge remains to procure enough blood products for each patient in medical need. Allocation of rare blood, ethical evaluation of transfusion triggers, attitudes towards refusing blood transfusion and provision of blood products to remote settings are areas which should receive consideration.

Education in transfusion medicine, Part III - The importance of haemovigilance education.

According to the literature, there are significant differences in the availability of education and training in transfusion medicine worldwide, with significant heterogeneity in the existing curricula. Recognising the need for education with the aim of achieving globally standardised competencies in transfusion medicine, a group of experts collaborating in the European and Mediterranean Initiative in Transfusion medicine (EMITm) proposed a process of incremental training and education. Subsequent to two previous papers published by this group on general education in transfusion medicine, this paper specifically refers to the field of education in haemovigilance. This topic is of particular importance when one considers the role of haemovigilance in improving the safety of transfusion practice, and the fact that this role can only be realised through the cooperation of all participants in the transfusion chain. In addition to promoting the importance of education in haemovigilance, this paper provides an overview of the available literature on this topic and proposes an education programme on haemovigilance for medical students and residents.

Thirty years of hemovigilance - Achievements and future perspectives.

Since its emergence in the early 1990s, hemovigilance has gradually evolved from a blood safety concept focused on surveillance of adverse reactions and events in patients, to a well-defined system that monitors the entire transfusion chain and improves its safety. The importance of hemovigilance has been recognized globally in a relatively short time, but the level of its implementation varies significantly between countries. The cooperation of international organizations has significantly contributed to the promotion, implementation, and education in this field. Thanks to initiatives taken, the safety of transfusion practice has been improved in many segments, primarily related to the risks of adverse events in recipients of blood components. In parallel with changing transfusion practice, the hemovigilance process has also matured. In addition to the reduction of existing risks and the early detection of emerging risks, hemovigilance has also embraced the principles of patient blood management. Research in hemovigilance is more increasingly focused on specific categories of patients, specific blood components and methods of their preparation, rare reactions, and transfusion efficacy and efficiency. A proactive approach and use of big data can play an important role in achieving these goals. Additional and sustained efforts should be made to prevent underreporting of events and to improve data comparability through clear definitions and grading systems. This review provides a historical overview of hemovigilance and its achievements, current challenges, and future plans.

How to improve issuing, transfusion and follow-up of blood components in Southern and Eastern Mediterranean countries? A benchmark assessment.

To determine the existence of guidelines regarding the appropriate clinical use of blood and blood components, transfusion requests, and blood issuing/reception documents and procedures. The different bedside transfusion organizations/processes and hemovigilance are also analyzed. The ultimate objective is to identify safe potential options in order to improve blood safety at the lowest cost. Data emanating from eight Arabic eastern/southern Mediterranean countries who responded to five surveys were collected and tabulated. National recommendations for the clinical use of blood components especially for hemoglobinopathies are lacking in some countries. In matter of good practices in the prescription, issuing and reception of BCs, efforts were made either on national or local basis. Procedures regarding patient information and ethical issues are still lacking. Almost all Mediterranean countries apply two blood testing procedures on each patient sample. Only Morocco, Tunisia and Algeria perform bed side blood group testing; Egypt and Lebanon perform antibody screen and antiglobulin cross matching universally. Automation for blood testing is insufficiently implemented in almost all countries and electronic release is almost absent. National hemovigilance policy is implemented in Tunisia, Morocco, and Lebanon but the reporting system remains inoperative. Insufficient resources severely hinders the implementation of expensive procedures and programs; however, the present work identifies safe procedures that might save resources to improve other parts in the transfusion process (e.g. electronic release to improve safety in issuing). Moreover, setting up regulations regarding ethics in transfusing recipients along with local transfusion committees are crucially needed to implement hemovigilance in transfusion practice.

The impact of vaccination on the burden of invasive pneumococcal disease from a nationwide surveillance program in Lebanon: an unexpected increase in mortality driven by non-vaccine serotypes.

BACKGROUND: The impact of pneumococcal conjugate vaccines (PCVs) on the burden of invasive pneumococcal disease (IPD) and serotype distribution was examined across age groups from data collected by the Lebanese Inter-Hospital Pneumococcal Surveillance Program. METHODS: Between 2005 and 2020, 593 invasive Streptococcus pneumoniae isolates were collected from 79 hospitals throughout Lebanon. Serotypes and antimicrobial resistance (AMR) profiles were identified, and trends compared over 3 eras: PCV7, post-PCV7/ pre-PCV13, and PCV13 eras. RESULTS: The prevalence of PCV7 serotypes decreased significantly from 43.6% in the PCV7 era to 17.8% during the PCV13 era (p<0.001). PCV13-only serotypes remained stable in the PCV13 compared to the post-PCV7 eras, especially serotypes 1 and 3, whereas non-vaccine types (NVT) increased throughout the study period, especially 24 and 16F. The mortality rate increased substantially from 12.5% (PCV7 era) to 24.8% (PCV13 era). A significant decrease in AMR was observed across the three study eras. CONCLUSION: PCVs substantially impacted IPD and AMR in vaccinated and unvaccinated populations despite an increase in mortality driven by NVT. Broadening the recommendation of vaccination to include older age-groups, using higher valency vaccines, and implementing stringent antimicrobial stewardship are likely to further impact the burden of IPD.

Radiology management of a 'breast unit' during COVID-19 pandemic: a single institution experience.

Aim: To describe the activity in the 'breast unit' at the department of radiology during the COVID-19 lockdown in a university hospital treating COVID-19 patients in a Middle-Eastern developing country. Materials: This was a retrospective study conducted from March 9 until 11 May 2020, in the breast unit at the department of radiology of a central university hospital in a Middle-Eastern developing country. Data were collected from 205 patients visiting the breast unit during the lockdown period and compared with the activity in the same period in the previous year. Results: Reduction of the breast unit activity was estimated at 73%. In addition, 153 mammograms, 205 ultrasounds, and 16 breast MRIs were done. Indications for mammogram were screening (41.5%), follow-up (22%), clinical symptoms (20%) and breast cancer surveillance (16.5%). MRI was performed mostly for preoperative surgical management. The rate of positive biopsies was 41%. All staff members and patients have accommodated to new adjustments. Conclusion: Activity in the breast unit dropped during the lockdown period. Staff should continue to seek their own and their patient's safety without diminishing the quality of healthcare.

Medical student education in transfusion medicine, part II: Moving forward to building up a "Know How" education program in transfusion medicine for under-graduate medical students.

There is a general trend in changing paradigm in teaching medicine; the emerging concept relies on a competence-based approach. Transfusion is either a discipline or a subsidiary of others depending on the countries and systems; this variability can be explained because transfusion is a medical care that is transdisciplinary. As a collective of professionals in both transfusion medicine practice and education, authors aim to propose a revision of the way education in transfusion medicine is delivered in this era of the 'global competency approach'. They advocate in favor of a Know How on 5 key issues: Diagnosing the patient condition in line with the Patient Blood Management principles; Facing acute blood loss; Addressing compatibility and avoiding immunization; Seeking for maximized benefits and dampening complications; and Inlaying competence within global health care issues, also comprising od economy. The methods used would be those developed for medical education at large, such as assessment tools. The global objective is to deliver the necessary competence to manage patients by an intern/resident. At the end of the curriculum, students should be able to self-evaluate the following items: 1) Do I know why my patient is anemic, thrombocytopenic, bleeding….? 2) Do I know the best approach to treat anemia, thrombocytopenia, bleeding (including the "no treatment" option)? 3) Do I know whether a transfusion approach is appropriate for my patients? 4) Do I know how to evaluate and anticipate benefits from blood transfusion and to avoid side-effects in the patient? 5) Do I know how to avoid unnecessary use of the products?

Neotectonics of the Sea of Galilee (northeast Israel): implication for geodynamics and seismicity along the Dead Sea Fault system.

The Sea of Galilee in northeast Israel is a freshwater lake filling a morphological depression along the Dead Sea Fault. It is located in a tectonically complex area, where a N-S main fault system intersects secondary fault patterns non-univocally interpreted by previous reconstructions. A set of multiscale geophysical, geochemical and seismological data, reprocessed or newly collected, was analysed to unravel the interplay between shallow tectonic deformations and geodynamic processes. The result is a neotectonic map highlighting major seismogenic faults in a key region at the boundary between the Africa/Sinai and Arabian plates. Most active seismogenic displacement occurs along NNW-SSE oriented transtensional faults. This results in a left-lateral bifurcation of the Dead Sea Fault forming a rhomb-shaped depression we named the Capharnaum Trough, located off-track relative to the alleged principal deformation zone. Low-magnitude (ML = 3-4) epicentres accurately located during a recent seismic sequence are aligned along this feature, whose activity, depth and regional importance is supported by geophysical and geochemical evidence. This case study, involving a multiscale/multidisciplinary approach, may serve as a reference for similar geodynamic settings in the world, where unravelling geometric and kinematic complexities is challenging but fundamental for reliable earthquake hazard assessments.

Difficulties in achieving a sustainable blood supply: report from the first national seminar on blood donation in Lebanon.

BACKGROUND: Lebanon has a decentralized/fragmented transfusion system. The current blood supply does not meet the World Health Organization target of achieving 100% voluntary non-remunerated blood donation (VNRD). There are currently 3 types of donors/donations in Lebanon: replacement/family donations (70-75%), VNRD (20-25%), and compensated donations (5-10%). Remunerated donations are illegal. AIMS: This report summarizes the content of presentations given during the first World Blood Donor Day seminar in Lebanon in June 2017. The aim is to describe the current Lebanese blood supply system and the major road blocks and to suggest practical recommendations that may assist in achieving 100% VNRD. METHODS: The content of presentations given during the first World Blood Donor Day seminar in Lebanon in June 2017 were summarized. RESULTS: The seminar was attended by all major stakeholders involved in transfusion medicine (Lebanese National Committee of Blood Transfusion, Hospital Blood Banks directors, Lebanese Army Blood Bank, Lebanese Red Cross and Donner Sang Compter). CONCLUSIONS: The Ministry of Public Health should focus on performing regular audits regarding the implementation of national guidelines. There is a need for a national blood supply committee, unifying all stakeholders in the transfusion and donation fields. Transfusion medicine should be declared by law as a public health issue and considered a priority for patient safety.

Quality and safety measures in transfusion practice: The experience of eight southern/eastern Mediterranean countries.

BACKGROUND AND OBJECTIVES: Blood transfusion is inherently associated with risks, and little is known regarding the available quality and safety measures in developing countries. No studies or census has been carried out, and therefore, no data on this compelling issue are available. MATERIALS AND METHODS: Data emanating from eight Arabic eastern/southern Mediterranean countries who responded to five surveys were collected and tabulated. RESULTS: Asepsis during phlebotomy, screening for serological and immuno-haematological parameters and appropriate storage conditions are maintained across all countries. Variations in blood component processing exist. Universal leucoreduction is systematically applied in Lebanon. Nucleic acid testing is only performed in Egypt. Aphaeresis procedure, leucoreduction and quality control for blood components are virtually inexistent in Mauritania. Written donor questionnaire is absent in Algeria and Tunisia. Most donor deferral periods for infectious agents are inconsistent with international standards. CONCLUSION: Gaps in the processing and in the quality/safety measures applied to the manufacture of blood components are quite evident in most eastern/southern Mediterranean countries. The decision of establishing an effective collaboration network and an independent body - aside from WHO - composed of specialists that oversees all transfusion activities in these countries is certainly a crucial step towards ensuring an optimum level of blood safety.

How to manage transfusion systems in developing countries: The Experience of Eastern and Southern Mediterranean countries.

OBJECTIVES: To outline and analyse the national organisation, infrastructure and management of transfusion systems in countries sharing common historical, cultural and economic features and to decipher management trends, in order to potentially benchmark. BACKGROUND: Little is known regarding transfusion systems in Eastern/southern Mediterranean at a time international organisations are calling for the establishment of a safe and sustainable blood system. MATERIALS AND METHODS: Data emanating from eight Arabic-speaking Eastern/Southern Mediterranean countries who responded to five surveys were collected and tabulated. RESULTS: While similarities in terms of supervision by national authorities, authorization of blood centres, quality control and management information system are evident, some significant divergence between these countries do exists. Only Lebanon does not possess a national blood establishment or organisation for blood supply. Blood components are fully government-subsidised in Algeria and Mauritania. Algeria, Morocco and Tunisia have a blood supply that relies mainly on Voluntary non-remunerated donors. Plateletpheresis is performed in all countries except Mauritania while plasmapheresis exists only in Algeria and Egypt. Morocco is the sole country outsourcing its plasma for Plasma derived products. CONCLUSION: Despite the various challenges facing these countries, lot of progresses have been made so far in the field of transfusion medicine. Yet, nationally coordinated blood programs overviewed by national regulatory authorities and actively supported by local governments are still needed to ensure the optimum level of blood safety.

Coronary Computed Tomographic Angiography Imaging as a Prognostic Indicator for Coronary Artery Disease: Data from a Lebanese Tertiary Center.

BACKGROUND: Coronary artery disease (CAD) is a major cause of death and disability worldwide. Coronary computed tomographic angiography (CCTA) is a noninvasive imaging technique with a high negative predictive value (NPV). Most studies were done in developed countries, where the prevalence of CAD does not reflect the actual disease burden in developing countries, such as Lebanon. METHODS: We retrospectively evaluated the prognostic value of CCTA in predicting acute myocardial events (AMEs) in 200 Lebanese patients. We determined if specific medical and radiological characteristics are linked with AME and looked for any association between the patient's medical risk factors and the type/location of detected atheromatous plaques. Patients' records were reviewed, and the follow-up period of 5-8 years ensued. Chi-square/Fisher test and Student's t-test were used, in addition to multinomial logistic regression to adjust for the confounding variables. P <0.05 was considered statistically significant. RESULTS: Our study showed that CCTA had a NPV that reaches 97.9% in asymptomatic patients, a positive predictive value (PPV) of 76.4% for symptomatic patients, a sensitivity of 88.9%, and a specificity of 52.5%. AMEs were significantly increased in patients with a mixed plaque type and/or a moderate-to-severe lumen reduction on CCTA. CONCLUSIONS: CCTA is a sensitive modality for plaque detection and is found to have a remarkably high NPV for asymptomatic patients. A CCTA, along with a low pretest clinical probability of CAD, can be sufficient to rule out an AME for up to 8 years.

Gender disparities are present in academic rank and leadership positions despite overall equivalence in research productivity indices among senior members of American Head and Neck Society (AHNS) Fellowship Faculty.

BACKGROUND: This study aims to examine potential disparities in scholarly performance based on sex, academic rank, leadership positions, and regional distribution of faculty in accredited Head and Neck Surgery fellowships in the United States. METHODS: Online faculty listings for 37 accredited fellowships were organized according to academic rank, leadership position, sex, and institutional location. Academic productivity was measured with three bibliometric indices: h-index, m-index, and the weighted relative citation ratio. RESULTS: A total of 732 faculty members were included, of which 153 (21%) were female. Fifty-eight males (89.2%) held leadership positions, compared to seven females (10.8%). There was no significant difference in overall productivity between male and female senior faculty. There were regional differences in productivity by sex. CONCLUSIONS: Females are underrepresented in senior faculty and within three common leadership positions, although scholarly productivity for male and female senior faculty and for those in leadership positions is similar.

Efficacy of indocyanine green fluorescence in predicting parathyroid vascularization during thyroid surgery.

BACKGROUND: We examined the value of indocyanine green (ICG) fluorescence angiography in predicting parathyroid vascularization following thyroid and central compartment surgeries. METHODS: Data were prospectively collected on adult patients undergoing thyroid and/or central compartment surgeries. Outcomes were compared in surgeries performed with and without ICG use. ICG scoring was used to quantify the vascularity of parathyroid glands. RESULTS: One hundred eleven patients were included; 43 (38.7%) patients underwent ICG injections. There was no significant difference in mean parathyroid hormone (PTH) changes at the end of surgery (29.24 vs 23.48 pg/mL, P = .38), symptomatic hypocalcemia (7.9% vs 3.9%, P = .37), or length of stay (1.095 ± 0.22 vs 0.912 ± 0.07 days, P = .51) between surgeries performed with and without ICG. The average vascularization score among individuals undergoing ICG angiography was 2.89 out of a maximum of 8 points. CONCLUSION: Low-flow ICG patterns are not associated with postoperative PTH changes or transient hypocalcemia and may lead to unnecessary parathyroid autotransplantation.

Surgery for Graves' disease in the era of robotic-assisted surgery: a study of safety and feasibility in the Western population.

PURPOSE: Thyroid surgery for Graves' disease is known to be associated with higher risk of complications. We seek to compare outcomes between robotic-assisted and open cervical approach thyroid surgery in patients with Graves' disease in the Western population. METHODS: We performed a retrospective cohort study using prospectively collected databases for patients undergoing robotic-assisted or conventional cervical approach thyroid surgery for Graves' disease at two academic medical centers, one in North America (New Orleans, LA) and one in Europe (Paris, France). RESULTS: A total of 102 patients were included, of which 56 (55%) underwent robotic thyroidectomy and 46 (45%) underwent conventional open cervical thyroidectomy. Mean age was 40.2 ± 13.2 years and 94 (92%) were females. Mean BMI for the sample was 27.7 ± 10.2 kg/m2. There was a trend towards larger specimen volume in the robotic-assisted group, 84.9 ± 62.2 cm3 versus 65.2 ± 40.5 cm3 (p = 0.07). Mean length of stay for the French patients undergoing robotic-assisted surgery was 3.2 ± 0.5 days. For the American cohort, length of stay was significantly shorter for robotic-assisted thyroidectomy, at 0.8 ± 0.4 days versus 1.0 ± 0.2 days (p = 0.003). Operative time was longer in patients who underwent robotic thyroidectomy (174.4 ± 33.5 min) compared to patients who underwent traditional cervical approach (121.2 ± 41.1 min, p < 0.0001). There was no difference in complication rates for the overall sample of patients undergoing robotic-assisted or open cervical procedures. CONCLUSION: Robotic thyroid surgery is safe in a select group of patients with Graves' disease in the Western population. Additional studies are warranted to further investigate these findings.

Medical student education in transfusion medicine: Proposal from the "European and Mediterranean initiative in transfusion medicine".

A large body of observations indicate that there is an inconsistent knowledge of Transfusion Medicine among health care professionals as well as inconsistent knowledge in all aspects of the transfusion process, from blood donation to transfusion on the ward. It is obvious to consider that appropriate education in Transfusion Medicine should be achieved in the education of specialists who will prescribe transfusion on a regular basis (hematologists, critical care specialists, anaethesiologists and others.) However,we also believe that education in Transfusion Medicine should also be delivered to almost all other medical specialists who may prescribe blood components. The variability in education of undergraduates in medical schools is universal most likely due to an absence of a predefined common platform. This paper, therefore, focuses on education at the undergraduate level and advocates coverage of the essential physiology and pathophysiology of blood as applied to blood transfusion as well as the medical and societal aspects of issues related to blood donation. It proposes incremental levels of training in Transfusion Medicine, with what is being therefore referred to as 'A', 'B', 'C' etc. curricula in ascending order of complexity; for example, 'A' and 'B' levels would involve medical, midwifery and nursing students, covering a broad base of the subject: they will be detailed in the present essay; ongoing further curricula will focus on physicians and other professionals working within the area or with responsibility for different aspects of the transfusion chain. It is intended that these courses include aspects of donor care, patient care and the appropriate use, safety and effectiveness of blood products. Next, it is advocated that curricula are addressed not only for high-income countries but also for middle- and low-income ones.

Can a decentralized blood supply system reach 100% voluntary nonremunerated donation?

Voluntary nonremunerated donation stands for the framework of a solid, safe, and sustainable blood supply; for this reason, the World Health Organization has set a goal toward achieving 100% voluntary nonremunerated blood donation in 2020. However, in Lebanon like in most developing countries, the majority of blood donations still come from family/replacement donors (around 75%) followed by voluntary donors for only 15%; compensated donors yet account for 10% of blood donations. Lebanon has a decentralized and fragmented blood supply system where private health care facilities predominate over the public system; thus, numerous challenges and roadblocks-that are discussed in this article-are likely to delay the fulfillment of the WHO resolution. By properly addressing (and resolving) those caveats, it should be expected that Lebanon can forecast achieving (or at least getting close to) 100% voluntary nonremunerated blood donation within the next decade.

Selective parathyroid venous sampling in primary hyperparathyroidism: A systematic review and meta-analysis.

OBJECTIVE: Minimally invasive parathyroidectomy requires accurate preoperative localization techniques. There is considerable controversy about the effectiveness of selective parathyroid venous sampling (sPVS) in primary hyperparathyroidism (PHPT) patients. The aim of this meta-analysis is to examine the diagnostic accuracy of sPVS as a preoperative localization modality in PHPT. METHODS: Studies evaluating the diagnostic accuracy of sPVS for PHPT were electronically searched in the PubMed, EMBASE, Web of Science, and Cochrane Controlled Trials Register databases. Two independent authors reviewed the studies, and revised quality assessment of diagnostic accuracy study tool was used for the quality assessment. Study heterogeneity and pooled estimates were calculated. RESULTS: Two hundred and two unique studies were identified. Of those, 12 studies were included in the meta-analysis. Pooled sensitivity, specificity, and positive likelihood ratio (PLR) of sPVS were 74%, 41%, and 1.55, respectively. The area-under-the-receiver operating characteristic curve was 0.684, indicating an average discriminatory ability of sPVS. On comparison between sPVS and noninvasive imaging modalities, sensitivity, PLR, and positive posttest probability were significantly higher in sPVS compared to noninvasive imaging modalities. Interestingly, super-selective venous sampling had the highest sensitivity, accuracy, and positive posttest probability compared to other parathyroid venous sampling techniques. CONCLUSION: This is the first meta-analysis to examine the accuracy of sPVS in PHPT. sPVS had higher pooled sensitivity when compared to noninvasive modalities in revision parathyroid surgery. However, the invasiveness of this technique does not favor its routine use for preoperative localization. Super-selective venous sampling was the most accurate among all other parathyroid venous sampling techniques. Laryngoscope, 2662-2667, 2018.

How Can Eastern/Southern Mediterranean Countries Resolve Quality and Safety Issues in Transfusion Medicine?

Unlike their Western counterparts, some of the Eastern/Southern Mediterranean countries lack centralized coordinated blood transfusion services leading to an unequal blood safety level. This was recently highlighted by a recent World Health Organization (WHO) regional committee report in which WHO urges these countries to establish and implement a national blood system with well-coordinated blood transfusion activities and to make attempts to reach 100% voluntary non-remunerated blood donation. The objective is thus to meet the same levels or standards as Western countries in term of self-sufficiency and blood safety. This raises the question whether these countries can either comply with Western countries' guidelines and experiences or develop their own safety scheme based on proper sociopolitical and economic features. Another option is to identify efficient and cost-effective strategies setup successfully in neighbor countries sharing cultural and economic features. To address this issue-and make an attempt to achieve this goal-we designed a number of surveys specifically addressed to Mediterranean countries, which were sent out to the national authorities; so far, five surveys aim at covering all aspects in blood collection, processing, testing, inventory and distribution, as well as patient immune-hematological testing and follow-up (including surveillance and vigilances). It is anticipated that such practice can help identifying and then sharing the more successful and cost-effective experiences, and be really focused on Mediterranean areas while not necessarily copying and pasting experiences designed for Western/Northern areas with significantly distinct situations.
