Abstract
Background: Cryptococcus neoformans is an opportunistic fungal pathogen that causes infections mainly in immunosuppressed individuals, such as transplant recipients. Aims: This study investigated the effects of rapamycin, an immunosuppressant drug, on the cellular organization, biophysical characteristics, and main virulence factors of C. neoformans. Methods: Morphological, structural, physicochemical and biophysical analyses of cells and secreted polysaccharides of the reference H99 C. neoformans strain were investigated under the effect of subinhibitory concentrations of rapamycin. Results: Rapamycin at a minimum inhibitory concentration of 2.5 μM reduced C. neoformans cell viability by 53%, decreased capsule, increased cell size, chitin and lipid body formation, and changed peptidase and urease activity. Conclusion: Further studies are needed to assess how rapamycin affects the virulence factors and pathogenicity of C. neoformans.

Abstract
Cryptococcosis is a systemic mycosis affecting immunosuppressed individuals, caused by various Cryptococcus species. The current treatment utilizes a combination of antifungal drugs, but issues such as nephrotoxicity, restricted or limited availability in certain countries, and resistance limit their effectiveness. Repurposing approved drugs presents a viable strategy for developing new antifungal options. This study investigates the potential of glatiramer acetate (Copaxone®) as a chemotherapy candidate for Cryptococcus neoformans infection. Various techniques are employed to evaluate the effects of glatiramer acetate on the fungus, including microdilution, XTT analysis, electron and light microscopy, and physicochemical measurements. The results demonstrate that glatiramer acetate exhibits antifungal properties, with an IC50 of 0.470 mg/mL and a minimum inhibitory concentration (MIC) of 2.5 mg/mL. Furthermore, it promotes enhanced cell aggregation, facilitates biofilm formation, and increases the secretion of fungal polysaccharides. These findings indicate that glatiramer acetate not only shows an antifungal effect but also modulates the key virulence factor-the polysaccharide capsule. In summary, repurposing glatiramer acetate as a potential chemotherapy option offers new prospects for combating C. neoformans infection. It addresses the limitations associated with current antifungal therapies by providing an alternative treatment approach.

Abstract
Abstract
Background
Almost one-third of repaired tetralogy of Fallot (TOF) and pulmonary stenosis (PS) patients referred for pulmonary valve replacement (PVR) have at least moderate tricuspid regurgitation (TR). Predictors of long term TR in this population are not well defined and the role of Tricuspid Annuloplasty (TA) in addition to PVR in this setting is controversial.
Purpose
Patients with preoperative severe TR or moderate TR with dilated tricuspid annulus (>40mm) undergo TA at the time of PVR as per protocol in our instititution. The aim of this observational study was to evaluate the long term results of this approach and to identify predictors of significant TR at the end of follow-up.
Material and methods
We retrospectively reviewed 35 repaired TOF and PS patients who underwent surgical PVR with (n=17, group 1) or without (n=18, group 2) TA in a single tertiary hospital between June-2009 and June-2021. Pre- and postoperative echocardiographic and cardiac magnetic resonance data were assessed for TR severity and right ventricle size and systolic function. Baseline and clinical follow up data were collected. Uni- and multivariable tests were used to analyze predictors of at least moderate TR after PVR.
Results
Mean age at PVR and baseline image parameters were comparable between groups, except for TR grade (p 0.006), tricuspid annulus size (p 0.018) and right ventricle outflow tract diameter (p 0.04) which were greater in group 1. TA did not confer and increased risk of surgical and peroperative complications. Intensive care unit (p 0.94) and total hospital admission days (p 0.59) did not differ among groups. At one year, TR grade significantly improved regardless of TA. At the end of follow-up (5.29±2.9 years), the degree of TR increased in both groups with no differences between groups (p 0.38) (see table 1). In univariable analysis, two independent predictors of at least moderate TR at end of follow-up were identified; mixed TR mechanism (OR 12.5, p 0.006) and severe preoperative TR grade (OR 10.21, p 0.003). Mixed TR mechanism (OR 15.78, p 0.01) and a right ventricle ejection fraction below 45% (OR 1.47, p 0.01) were identified as risk factors of significant TR in multivariable analysis (see Table 2).
Conclusions
TA seems a reasonable approach at the time of PVR in patients with severe TR or moderate TR with dilated annulus. Mixed TR mechanism and a worse right ventricular function have been identified as independent predictors factors of long term significant postoperative TR in our study cohort.

Abstract
A 66-year-old man presented with asymptomatic right testicular swelling. He was known to be infected with HIV and was non-adherent to treatment. He was recently treated for nasal leishmaniasis. Surgical drainage was performed and eventually, an orchiectomy was required. A post-mortem diagnosis was made of disseminated histoplasmosis. Testicular infection due to H. capsulatum is rare, with only a few cases being reported. Here we present a case of testicular histoplasmosis, followed by a literature review.

Abstract
Abstract
Background
Skin cancer represents the most common malignancy worldwide and it is imperative that we develop strategies to ensure safe and sustained delivery of cancer care which are resilient to the ongoing impact of COVID-19.
Objective
This study prospectively evaluates the COVID-19 related patient risk and skin cancer management at a single tertiary referral centre, which rapidly implemented national COVID-safety guidelines.
Method
A prospective cohort study was performed in all patients who underwent surgery for elective skin cancer service management, during the UK COVID-19 pandemic peak (April-May 2020). ‘Real-time’ 30-day hospital database deceased data were collected. Random selection was undertaken for patients who either underwent operative (surgery group) management or remained on the waiting list (control group); these groups were also prospectively followed-up within a controlled cohort study design and telephoned at the end of June 2020 for the control group or 30 days post-operatively.
Results
Of the 767 patients who had operations, there were no COVID-19 related deaths. Both the surgery (n = 384) and control (n = 100) groups were matched for age, sex, ethnicity, BMI, presence of comorbidities, smoking and positive COVID-19 contact. There were no differences in post-operative versus any symptom development (1.3%, 5/384 vs. 4%, 4/100, p = 0.093), or proportion of positive tests (8.6%, 33/384 vs. 8%, 8/100; p = 0.849), between the surgery and control groups.
Conclusions
These data support continued and safe service provision, and no increased risk to skin cancer patients who require surgical management, which is vital for continuation of cancer treatment in the context of a pandemic.

Abstract
Abstract
Background
Adult patients with single ventricle (SV) physiology who had not undergone Fontan palliation are uncommon. Little is known about their clinical features and outcomes.
Objective
This study aims to describe the clinical features, cardiovascular outcomes and long-term survival of patients with SV physiology without Fontan palliation.
Methods
Data were collected retrospectively from SV physiology patients followed in adult congenital heart disease (ACHD) units of five tertiary referral centers. None of them had Fontan palliation. Baseline data were recorded on the first visit at ACHD unit. Death was considered as main endpoint. Other outcomes such as atrial or ventricular arrhythmias, endocarditis, ICD or pacemaker implantation, admission for heart failure and heart transplant were also collected and analyzed. Association between clinical/analytical baseline variables and death was also evaluated by univariate Cox regression.
Results
128 patients were included. On the first visit, mean age was 32.3±10.9 years, being the most common defect double inlet left ventricle (63p, 49.2%). The single ventricle had left morphology in 106 cases (82.8%). At baseline mean heaemglobin was 19.1±2.8 g/dl, mean O2 Sat 83±6.9% and 46 patients (36%) had a NYHA status III or IV. 4 different groups were found: a) Unrestricted pulmonary flow with Eisenmenger physiology (24p, 18.8%); b) Restricted forward pulmonary flow with or without pulmonary banding (46p, 35.9%); c) Aortopulmonary shunts as a source of pulmonary flow (20p, 15.5%) and d) cavopulmonary shunt (Glenn) as a definitive palliation (38p, 29.7%). After 7.3±4.1 years follow-up, mortality was 22.7% (29 patients), being sudden death (9p, 7%) the most frequent cause. Survival rate at 5 and 10 years of follow-up were 85% and 76% respectively (Figure 1). About of the rest of the outcomes, highlighting a high rate of atrial tachycardia (38.3%), admission for heart failure (23.4%), stroke (17.2%), endocarditis (9.4%), pacemaker/ICD implantation (11.8%). Baseline variables associated with higher mortality were: older age (HR=1.1 [1.004–1–087]); NYHA III or IV (HR=5.5 [2.4–12.4]); thrombocytopenia (HR=1.01 [1.001–1.003]); anticoagulant treatment (HR=2.6 [1.7–3.9]); glomerular filtration rate below 60 ml/min (HR=3.77 [1.5–9.6]); QRS width (HR=1.03 [1.01–1.05]); atrial arrhythmias (HR=3.1 [1.5–6.5]); moderate or severe AV valve regurgitation (HR=1.5 [1.15–1.97]) and ventricular ejection fraction (HR=0.94 [0.91-0.97]).
Conclusions
Adults survivors with SV physiology without Fontan palliation have a high mortality and frequently suffer from serious cardiovascular events. Several clinical (NYHA status, previous atrial arrhythmias, anticoagulant treatment), analytical (renal function, thrombocytopenia), ECG (QRS width) and echocardiography (AV valve regurgitation and EF) factors can identify patients at higher risk of death.

Abstract
Abstract
Background
Patients with univentricular physiology who do not complete the palliation to Fontan are a heterogeneous group with unknown long term outcome.
Aims
This study aimed at describing the clinical course and long-term survival of patients with SV physiology with restricted pulmonary flow that had not undergone a Fontan type of repair.
Methods
From the prospectively maintained databases of the adult congenital cardiac units of five tertiary referral centers, data from all SV physiology patients were obtained. Patients completing a Fontan type palliation or developing Eisenmenger physiology and segmental pulmonary hypertension were excluded. Baseline data were recorded on the first visit at adult congenital heart disease (ACHD) unit. The primary end point was death.
Results
101 patients (50.5% females) were identified. Mean age at end of follow up was 39.3±11.3 years. Of these, 45 (44.6%) were unoperated (group 1, restricted forward pulmonary flow with or without pulmonary banding), 38 (37.6%) had undergone a cavopulmonary shunt as a definitive palliation (group 2) and 18 (17.8%) had aortopulmonary shunts (group 3). The main diagnosis was double inlet left ventricle (DILV) (N: 52, 51.5%) and most of the ventricle was left (82.2%). The principal reason for not performing a Fontan repair was mean pulmonary artery pressure >18 mmHg. At initial visit at the ACHD unit patients were 32.2±11.1 years of age. 35% of the patients were in NYHA class III-IV, with no differences between groups. However, patients in group 2 had worse oxygen saturation (p=002) and higher haemoglobin (p=0.037). After a mean follow-up of 7.3±4.1 years, mortality was 20.8% (21 patients), being sudden death (7p, 6.9%) the most frequent cause. Patients in group 3 showed worse ventricular function (p=0.0001) and a trend to higher mortality that did not reach statistical significance (HR 2.7, CI 95% 0.91–8.14, P=0.07).
Conclusions
Patients with single ventricle physiology not undergoing Fontan repair are a population of high risk, with sudden death as main driver of mortality. Patients palliated with aortopulmonary shunts are prone to worse ventricular function and a trend to higher mortality.

Abstract
Abstract
Introduction
Patients with D-transposition of the great arteries (TGA) treated with Senning or Mustard surgery develop supraventricular tachycardias (SVTs) that require treatment with ablation. The use of multipoint, high-density, wavefront-activation-orientation independent mapping catheters hasn’t been reported in literature.
Purpose
To describe the feasibility of using a specific mapping catheter in SVTs in this set of patients.
Methods
Prospective observational study in patients with history of SVT and atrial switch surgery, that underwent EP study and electroanatomic (EA) mapping with a new 8Fr deflectable, multipoint (16 equidistant electrodes along 4 splines), with magnetic sensor, wavefront-activation-orientation independent catheter, in a third level hospital since April 2018 until May 2019, with medium-term follow-up.
Results
A total of 8 EPS (electrophysiologic studies) were performed in 7 patients (clinical data in Table 1). One patient had a tachycardia recurrence, accounting for a second EPS. The pulmonary venous atrium (PVA) was mapped in all procedures, whereas the systemic venous atrium (SVA) was mapped only in 75% of them, A total of 15 EA maps were obtained, with a ratio of 1.9 maps/patient, and an average of 20 375 ± 13 045 total points per patient. In all cases, PVA mapping was performed via retrograde transaortic approach, without transbaffle puncture. Tachycardia was induced in 5 out of 8 procedures, obtaining 6 different tachycardias (4 CTI dependent macro-reentry: 3 w/anticlockwise activation; 1 localized re-entry in SVA; 1 focal AT in SVA). No arrhythmia was induced in the other 3 procedures, however, in a patient with a previous CTI ablation, evidence of a gap in the ablation line on the voltage map was found. Ablation was performed with an irrigated, contact force, 3.5 mm catheter in 6 of the 8 procedures (75%). A retrograde transaortic approach was used in 3 of CTI dependent macro-reentries (75%). In one patient (who underwent two procedures) ablation was performed through a baffle leak. We report an acute success rate of ablation of 100%, and a recurrence rate of 20% on medium-term follow up. There were no major complications; nonetheless, one patient with history of morbid obesity had a minor vascular complication on the femoral puncture site treated medically.
Conclusions
it’s feasible and safe to use this new mapping catheter in patients with history of atrial switch surgery, both via retrograde and anterograde approach on the PVA and SVA respectively. The most frequent tachycardia observed in this study was anticlockwise CTI-dependent atrial flutter.

Abstract
The objective of this study was to evaluate women's knowledge of methods for screening breast cancer. The study was done on a population of women aged 18 or over in the city of Rio Grande between April and November 2011. Interviewers used questionnaires on all of the women at selected households. Models were developed for every type of screening (self-examination of breasts, mammography, and clinical exams) that were analyzed through the use of Poisson regression. Out of the 1596 women interviewed, 1355 reported self-examination, 456, mammography, and only 191, clinical examination of the breast, performed by a health professional, as important for the prevention of breast cancer. White women with 11 years or more worth of schooling had a greater probability of having mammography exams and clinical examinations as methods for screening. We noted, linked to the aforementioned, that there was a linear tendency whereby there was a greater probability for those with high incomes to undergo one of the above interventions. The study noted that there was a need for more detailed information aimed at the population on prevention methods in order to avoid late diagnosis. We noted that non-white women with little education and on low incomes showed less knowledge of clinical examination methods and mammographies.

Abstract
DNAJC17 is a heat shock protein (HSP40) family member, identified in mouse as susceptibility gene for congenital hypothyroidism. DNAJC17 knockout mouse embryos die prior to implantation. In humans, germline homozygous mutations in DNAJC17 have been found in syndromic retinal dystrophy patients, while heterozygous mutations represent candidate pathogenic events for myeloproliferative disorders. Despite widespread expression and involvement in human diseases, DNAJC17 function is still poorly understood. Herein, we have investigated its function through high-throughput transcriptomic and proteomic approaches. DNAJC17-depleted cells transcriptome highlighted genes involved in general functional categories, mainly related to gene expression. Conversely, DNAJC17 interactome can be classified in very specific functional networks, with the most enriched one including proteins involved in splicing. Furthermore, several splicing-related interactors, were independently validated by co-immunoprecipitation and in vivo co-localization. Accordingly, co-localization of DNAJC17 with SC35, a marker of nuclear speckles, further supported its interaction with spliceosomal components. Lastly, DNAJC17 up-regulation enhanced splicing efficiency of minigene reporter in live cells, while its knockdown induced perturbations of splicing efficiency at whole genome level, as demonstrated by specific analysis of RNAseq data. In conclusion, our study strongly suggests a role of DNAJC17 in splicing-related processes and provides support to its recognized essential function in early development.

Abstract
OBJECTIVE To simplify and optimize the ability of EuroSCORE I and II to predict early mortality after surgery for infective endocarditis (IE). METHODS Multicentre retrospective study (n = 775). Simplified scores, eliminating irrelevant variables, and new specific scores, adding specific IE variables, were created. The performance of the original, recalibrated and specific EuroSCOREs was assessed by Brier score, C-statistic and calibration plot in bootstrap samples. The Net Reclassification Index was quantified. RESULTS Recalibrated scores including age, previous cardiac surgery, critical preoperative state, New York Heart Association >I, and emergent surgery (EuroSCORE I and II); renal failure and pulmonary hypertension (EuroSCORE I); and urgent surgery (EuroSCORE II) performed better than the original EuroSCOREs (Brier original and recalibrated: EuroSCORE I: 0.1770 and 0.1667; EuroSCORE II: 0.2307 and 0.1680). Performance improved with the addition of fistula, staphylococci and mitral location (EuroSCORE I and II) (Brier specific: EuroSCORE I 0.1587, EuroSCORE II 0.1592). Discrimination improved in specific models (C-statistic original, recalibrated and specific: EuroSCORE I: 0.7340, 0.7471 and 0.7728; EuroSCORE II: 0.7442, 0.7423 and 0.7700). Calibration improved in both EuroSCORE I models (intercept 0.295, slope 0.829 (original); intercept -0.094, slope 0.888 (recalibrated); intercept -0.059, slope 0.925 (specific)) but only in specific EuroSCORE II model (intercept 2.554, slope 1.114 (original); intercept -0.260, slope 0.703 (recalibrated); intercept -0.053, slope 0.930 (specific)). Net Reclassification Index was 5.1% and 20.3% for the specific EuroSCORE I and II. CONCLUSIONS The use of simplified EuroSCORE I and EuroSCORE II models in IE with the addition of specific variables may lead to simpler and more accurate models.

Abstract
Establishment of continuous cell lines from human normal and tumor tissues is an extended and useful methodology for molecular characterization of cancer pathophysiology and drug development in research laboratories. The exchange of these cell lines between different labs is a common practice that can compromise assays reliability due to contamination with microorganism such as mycoplasma or cells from different flasks that compromise experiment reproducibility and reliability. Great proportions of cell lines are contaminated with mycoplasma and/or are replaced by cells derived for a different origin during processing or distribution process. The scientific community has underestimated this problem and thousand of research experiment has been done with cell lines that are incorrectly identified and wrong scientific conclusions have been published. Regular contamination and authentication tests are necessary in order to avoid negative consequences of widespread misidentified and contaminated cell lines. Cell banks generate, store and distribute cell lines for research, being mandatory a consistent and continuous quality program. Methods implementation for guaranteeing both, the absence of mycoplasma and authentication in the supplied cell lines, has been performed in the Andalusian Health System Biobank. Specifically, precise results were obtained using real time PCR detection for mycoplasma and 10 STRs identification by capillary electrophoresis for cell line authentication. Advantages and disadvantages of these protocols are discussed.

Abstract
AIM The aims of this project were to analyze the factors that influence quality and safety of tissues for transplantation and to develop the method to ensure standards of quality and safety in relation to tissue banking as demanded by European Directive 2004/23/EC and its technical annexes. It is organized in 4 Working Groups, the objectives of each one being focused in a specific area. STANDARDS The Guide of Recommendations for Tissue Banking is structured into 4 parts: (1) quality systems that apply to tissue banking and general quality system requirements, (2) regulatory framework in Europe, (3) standards available, and (4) recommendations of the fundamental quality and safety keypoints. REGISTRY This Working Group handled design of a multinational musculoskeletal tissue registry prototype. TRAINING This Working Group handled design and validation of a specialized training model structured into online and face-to-face courses. The model was improved with suggestions from students, and 100% certification was obtained. AUDIT The Guide for Auditing Tissue Establishments provides guidance for auditors, a self-assessment questionnaire, and an audit report form. The effectiveness and sustainability of the outputs were assessed. Both guides are useful for experienced tissue establishments and auditors and also for professionals that are starting in the field. The registry prototype proves it is possible to exchange tissues between establishments throughout Europe. The training model has been effective in educating staff and means having professionals with excellent expertise. Member states could adapt/adopt it. The guides should be updated periodically and perhaps a European organization should take responsibility for this and even create a body of auditors.

Abstract
PURPOSE The purpose of this study was to analyse the possible differences, especially those regarding mortality, between patients hospitalized for community-acquired pneumonia (CAP) with and without chronic obstructive pulmonary disease (COPD), and the risk factors related to mortality in the COPD group. METHODS 710 patients with CAP were included in a prospective multicenter observational study. 244 of the patients had COPD confirmed by spirometry. RESULTS COPD was associated with mortality in patients with CAP (OR=2.62 CI: 1.08-6.39). Patients with COPD and CAP had a significantly higher 30-day mortality rate as compared to patients without COPD. Multivariate analysis showed that PaO(2)< or =60 mmHg (OR=7.95; 95% CI: 3.40-27.5), PaCO(2)> or =45 mmHg (OR=4.6; CI: 2.3-15.1); respiratory rate > or =30/min (OR=12.25; CI: 3.45-35.57), pleural effusion (OR=8.6; 95% CI: 2.01-24.7), septic shock (OR=12.6; 95% CI: 3.4-45.66) and renal failure (OR=13.4; 95% CI: 3.2-37.8) were significantly related to mortality. Purulent sputum and fever were considered as protective factors. CONCLUSIONS COPD was an independent risk factor for mortality in patients with CAP. Hypoxemia and hypercapnia are associated with mortality in patients with CAP with and without COPD. Chronic obstructive pulmonary disease and PaCO(2) value could be useful prognostic factors and should be incorporated in risk stratification in patients with CAP.

Abstract
OBJECTIVES To determine whether self-perceived memory impairment is associated with the severity of white matter changes (WMC) and is related to cognitive impairment. METHODS Data were drawn from the multinational Leukoaraiosis and Disability Study (LADIS), which investigates the impact of WMC on global functioning. WMC severity was rated using the Fazekas scale. Medial temporal lobe atrophy (MTA) was scored visually and mean values were calculated. The neuropsychological battery consisted of the Mini-Mental State Examination, a modified version of the VADAS-Cog, Trail making and Stroop tests. A question about self-perceived memory impairment was used as a measure for presence of memory complaints. Cognitive performance was analysed test-by-test and in three main domains: memory, executive functions and speed/motor control. The Geriatric Depression Scale (GDS) was used as a measure of depressive symptoms. RESULTS Six hundred and thirty-eight subjects were included in this study. No association was found between memory complaints and the severity of WMC. Subjects with memory complaints (n = 399) had a higher GDS score [t((637)) = -7.15; p<0.02] and performed worse on almost all cognitive tests and on the three cognitive domains. Multiple linear regression showed that the worse performance on the memory domain was associated with memory complaints independently of depressive symptoms, WMC severity and MTA (R(2) = 0.183; F = 17.09, beta = -0.126; p<0.05). CONCLUSION In a sample of non-disabled elderly subjects with WMC, self-perceived memory impairment is significantly associated with objective memory impairment independently of the WMC severity, depressive symptoms and MTA.

Abstract
The main objective of European Quality System for Tissue Banking (EQSTB) project was to analyze throughout different working areas the factors that may influence the final tissue quality and safety for transplantation, providing greater benefit to recipients. Fifteen national organizations and tissue establishments from 12 European countries took part in this project. The Sanco-EQSTB project was organized in four Working Groups. The objectives of each was focused on a specific area. The Standards Working Group analyzed different standards or guides used in various European tissue banks as a quality and safety system. The Registry Working Group created a Tissue Registry through a multinational European network database. The Education Working Group created a specialized training model for tissue bank personnel. The Audit Working Group created an European model of Auditing for tissue establishments. The aim of this article was to describe the activities of Working Group 3 in designing and validating a specialized training model among tissue bank personnel that could become the approved education system recommended by European Union members.

Abstract
Spain is the leader country in cadaver kidney transplantation. However the percentage of those transplants coming from living donors represents only a 2% of the total activity. To analyze the cause of this situation the Spanish Society of Nephrology and the National Transplant Organization carried out an opinion pole between patients and health professionals including nephrologists, surgeons/urologists and nurses implicated in kidney transplantation. 60% out the patients consider that the time into the waiting list is to long and 59% don't have any information about living donor kidney transplantation. All the health professionals believe that living donor share better results than get cadaver donors and that the number of the procedure are not enough. Considering that scarcely motivation of professionals and the family of the patients are the main cause. Parents, brothers and sister were considered the best match between donor and recipients and non genetically/emotionally-related donors were accepted by only 2.5%. A 55.7% out of the health professionals considered that the nephrologists are the people that must inform the patients and family about living kidney donation.

Abstract
BACKGROUND The maintenance of an equitable system for access to transplantation is a matter of concern to all professionals involved in this field. Any national system must ensure equity. METHODS The rates of indication for liver transplantation have been reviewed for all Spanish regions. The time to transplantation was evaluated with respect to different recipient characteristics and donor rates. The indication rates for liver transplantation are similar in the different countries with liver transplant programs but are far from similar among different regions in Spain. This suggests that there is not equity in the access to liver transplantation. RESULTS A review of the factors affecting the waiting times to transplantation after being registered for the waiting list shows that some groups of patients are currently waiting less time than others. Shorter waiting times occur in patients of the AB group, children, patients with hepatocarcinoma, and patients living in the zone of Valencia, despite similar organ donation rates in all transplant zones. CONCLUSION Neither the rate nor the probability of liver transplantation is affected exclusively by the organ donation rate in Spain but also depends on the number of patients admitted to the waiting list. Despite the existence of an organ allocation system that is center-oriented, liver patients are receiving grafts mainly based on the severity of the illness, because clearance rates from the waiting list of both dead patients and grafted patients are the same.

Abstract
The need to face the increasing gap between the supply and the demand of transplants has led to the development of a permanent network of trained medical staff responsible for the organ donation and removal process in all centers accredited for that process. In Spain, this activity received a specific budget, like any other medical activity in hospitals, and the responsible staff became accountable for performance. This system dramatically increased the number of potential donors referred, not only young donors with trauma, but also elderly donors dying from stroke. The effect was that the donation rate increased by more than 100% in 10 years (from 14 to 34 donors per million population). Consequently, so did all the transplant figures. In some areas, such as Catalonia, it has been demonstrated that sustained kidney transplant activity of over 60 procedures per million population can maintain or slightly decrease the waiting list, despite increasing incidence and prevalence of end-stage renal failure. Quality monitoring of the donation and retrieval process shows that there are still opportunities for improvement if all potential donors are referred and all technical problems are overcome. Living donation and nonheart beating organ retrieval should also be promoted.

Abstract
In Spain, the number of donors per million of population and the activity of transplantation is a direct consequence of the continued work of the hospital transplant coordinators. There are 146 procurement hospitals with approximately 534 transplant coordinators (13.6 coordinators per hospital and 12.7 per million of population). A voluntary survey of 74 Spanish transplant coordinators revealed 67.6% to be men and 32.4% women of average age 43 years with specialization of 75.7%, Intensive Care Medicine; 8.1%, Anesthesiology; 6.7%, Nephrologists; and the rest, General Surgery or without any specialization. Among the group who responded to the injury, 86.5% were doctors and 13.5%, nurses. The overall team is composed of 52% doctors, 27.7% nurses and others with 70.3% working part-time and 27%, full-time. Previous experience was noted to be less than 5 years among 51.4%, and more in the rest of the cases. The 85% work under medical direction by management. Their payment includes salary plus activity in 48.7% of the cases; 21.6%, only salary, and 18.9%, only activity. Each coordinator generates between 3 and 7 organ as well as 3 and 11 of tissue donors. In conclusion, comparing this data with the practice in the United States demonstrates the unique aspects of the Spanish system.

Abstract
During recent years organ donation in Spain has increased by 100%, with important changes seen in the donor profile. Mean age has increased by more than 10 years, being nowadays more than 33% of our donors over 60 years. Ten years ago road traffic trauma was the main cause of death, while now most of our donors die due to stroke and only 21% die in a traffic accident. This changes lead to an increase in the number of kidneys discarded for transplantation every year. Among the 2517 kidneys retrieved during 2001, 567 were discarded, mainly due to different glomerular, interstitial or vascular pathologic damage. The older is the donor the higher is the percentage of kidneys discarded. It has to be underlined that an increased number of livers from donors, whose kidneys could not be used, are being grafted (141 in 2001 over 281 donors from whom no kidney could be grafted and over a total number of 1335 donors). Only 5% of kidneys were discarded due to technical problems. An important number of kidneys were discarded due to malignancy suspicion or diagnosis (12.3%). Organ donation has improved but kidney transplantation did not in parallel, due to the increasing number of kidneys discarded for transplantation in close relation with the evolution of donor's characteristics. Organ donation rate is around 33 donors per million population while efficient organ donation rate is around 30 donors per million. Only from 67% of donors both kidneys can be grafted and from 20% of donors no kidney can be used. These data will not change our policy, at least by the moment, we will continue to evaluate every potential brain death donor with the aim of studying if organs can be used. It is true that in 50% of cases over 70 years no organ can be used after retrieval and microscopic exam, but in the other 50% we can proceed.
