ABSTRACT

PURPOSE: Evaluate the percentage of patients with prostate cancer treated with luteinizing hormone-releasing hormone analogues (LHRHa) that develop castration resistance after a follow-up period of 3 years. The secondary objective is to evaluate the variables potentially related to the progression to castration resistant prostate cancer (CRPC). METHODS: A post-authorization, nation-wide, multicenter, prospective, observational, and longitudinal study that included 416 patients treated with LHRHa between 2012 and 2017 is presented. Patients were followed for 3 years or until development of CRPC, thus completing a per-protocol population of 350 patients. A Cox regression analysis was carried out to evaluate factors involved in progression to CRPC. RESULTS: After 3 years of treatment with LHRHa 18.2% of patients developed CRPC. In contrast, in the subgroup analysis, 39.6% of the metastatic patients developed CRPC, compared with 8.8% of the non-metastatic patients. The patients with the highest risk of developing CRPC were those with a nadir prostate-specific antigen (PSA) > 2 ng/ml (HR 21.6; 95% CI 11.7-39.8; p < 0.001) and those receiving concomitant medication, most commonly bicalutamide (HR 1.8; 95% CI 1-3.1, p = 0.0431). CONCLUSIONS: The proportion of metastatic patients developing CRPC after 3 years of treatment with LHRHa is consistent with what has been previously described in the literature. In addition, this study provides new findings on CRPC in non-metastatic patients. Concomitant medication and nadir PSA are statistically significant predictive factors for the time to diagnosis of CRPC, the nadir PSA being the strongest predictor.

ABSTRACT

Background: Clear-cell renal cell carcinoma (ccRCC) is the most common and aggressive form of renal cancer and a paradigm of inter- and intratumor heterogeneity. We carried out an exploratory digital spatial profiling of the tumor interior and periphery of two ccRCC tumor specimens and mapped spatially the molecular and cellular composition of their tumor microenvironment and ecosystem. Materials and methods: Digital spatial profiling of the whole transcriptome of 19 regions of interest (ROIs) was carried out from two selected highly immunogenic stage pT3a/grade 3 (G3) and stage pT3a/grade 4 (G4) ccRCC. A total of 9-10 ROIs were selected from distinct areas from each tumor, including tumor interior and tumor periphery, and differences in gene expression were analyzed by RNA sequencing, pathway enrichment analysis, and cell deconvolution. Results: The distinct areas from the two locally advanced tumors displayed unique gene expression spatial patterns defining distinct biological pathways. Dimensional reduction analysis showed that the G3 ccRCC, compared to the G4 ccRCC, correlated with more variability between regions from the tumor interior and tumor periphery. Cell deconvolution analysis illustrated higher abundance of immune cells, including macrophages, myeloid dendritic cells, and CD4 T cells, and lower abundance of regulatory T cells in the tumor periphery compared to the tumor interior. Conclusions: Transcriptome spatial profiling revealed high inter- and intratumor heterogeneity in the analyzed tumors and provided information with potential clinical utility. This included the finding of less intratumor heterogeneity and more tumor-infiltrated T cells in the ccRCC tumor specimen with a higher grade.

ABSTRACT

INTRODUCTION: To examine pooled efficacy data from three, large phase III studies comparing mirabegron (50 and 100 mg) with placebo, and pooled safety data including additional mirabegron 25 mg and tolterodine extended release (ER) 4 mg results. METHODS: This prespecified pooled analysis of three randomised, double-blind, placebo-controlled, 12-week studies, evaluated efficacy and safety of once-daily mirabegron 25 mg (safety analysis), 50 or 100 mg (efficacy and safety analyses) and tolterodine ER 4 mg (safety analysis) for the treatment of symptoms of overactive bladder (OAB). Co-primary efficacy measures were change from baseline to Final Visit in the mean number of incontinence episodes/24 h and mean number of micturitions/24 h. Key secondary efficacy end-points included mean number of urgency episodes/24 h and mean volume voided/micturitions, while other end-points included patient-reported outcomes according to the Treatment Satisfaction-Visual Analogue Scale (TS-VAS) and responder analyses [dry rate (posttreatment), ≥ 50% reduction in incontinence episodes/24 h, ≤ 8 micturitions/24 h (post hoc analysis)]. The safety analysis included adverse event (AE) reporting, laboratory assessments, ECG, postvoid residual volume and vital signs (blood pressure, pulse rate). RESULTS: Mirabegron (50 and 100 mg once daily) demonstrated statistically significant improvements compared with placebo for the co-primary end-points, key secondary efficacy variables, TS-VAS and responder analyses (all comparisons p < 0.05). Mirabegron is well tolerated and demonstrates a good safety profile. The most common AEs (≥ 3%) included hypertension, nasopharyngitis and urinary tract infection (UTI); the incidence of hypertensive events and UTIs decreased with increasing dose. For mirabegron, the incidence of the bothersome antimuscarinic AE, dry mouth, was at placebo level and of a lesser magnitude than tolterodine. CONCLUSION: The efficacy and safety of mirabegron are demonstrated in this large pooled clinical trial dataset in patients with OAB.

ABSTRACT

Extraction of high-quality genomic DNA for PCR amplification from filamentous fungi is difficult because of the complex cell wall and the high concentrations of polysaccharides and other secondary metabolites that bind to or co-precipitate with nucleic acids. We developed a modified sodium dodecyl sulfate/phenol protocol, without maceration in liquid nitrogen and without a final ethanol precipitation step. The A(260/280) absorbance ratios of isolated DNA were approximately 1.7-1.9, demonstrating that the DNA fraction is pure and can be used for analysis. Additionally, the A(260/230) values were higher than 1.6, demonstrating negligible contamination by polysaccharides. The DNA isolated by this protocol is of sufficient quality for molecular applications; this technique could be applied to other organisms that have similar substances that hinder DNA extraction. The main advantages of the method are that the mycelium is directly recovered from culture medium and it does not require the use of expensive and specialized equipment.

ABSTRACT

OBJECTIVE: Stereoelectroencephalography (SEEG) is a technique for preoperative evaluation of patients with difficult-to-localise refractory focal epilepsy (DLRFE), enabling the study of deep cortical structures. The procedure, which is increasingly used in international epilepsy centres, has not been fully developed in Spain. We describe our experience with SEEG in the preoperative evaluation of DLRFE. MATERIAL AND METHODS: In the last 8 years, 71 patients with DLRFE were evaluated with SEEG in our epilepsy centre. We prospectively analysed our results in terms of localisation of the epileptogenic zone (EZ), surgical outcomes, and complications associated with the procedure. RESULTS: The median age of the sample was 30 years (range, 4-59 years); 27 patients (38%) were women. Forty-five patients (63.4%) showed no abnormalities on brain MR images. A total of 627 electrodes were implanted (median, 9 electrodes per patient; range, 1-17), and 50% of implantations were multilobar. The EZ was identified in 64 patients (90.1%), and was extratemporal or temporal plus in 66% of the cases. Follow-up was over one year in 55 of the 61 patients undergoing surgery: in the last year of follow-up, 58.2% were seizure-free (Engel Epilepsy Surgery Outcome Scale class I) and 76.4% had good outcomes (Engel I-II). Three patients (4.2%) presented brain haemorrhages. CONCLUSION: SEEG enables localisation of the EZ in patients in whom this was previously impossible, offering better surgical outcomes than other invasive techniques while having a relatively low rate of complications.

ABSTRACT

BACKGROUND. The rarest location of pilocytic astrocytoma is intramedullary. Gliomas represent up to 24 - 30% of intramedullary tumors in adulthood and are second only after ependymomas. Leptomeningeal dissemination through cerebrospinal fluid is unusual and occurs predominantly in medulloblastomas, ependymoblastomas, central neuroblastomas, ependymomas, germ cell tumors and high-grade gliomas. The majority of spinal cord gliomas reporting metastasis were anaplastic astrocytomas or glioblastomas multiforme and relatively few were low-grade gliomas. The incidence of leptomeningeal spread of low-grade tumors is rare. A rare cranial extension of brain leptomeningeal dissemination in an intramedullary pilocytic astrocytoma during adulthood is reported. CASE REPORT. A 51 year-old-man with a recurrent intramedullary mass at C5-C7 level operated 4 times with all pathological anatomy reports describing the lesion as Pilocytic Astrocytoma developed, after 15 years from the diagnosis, visual hallucinations and his level of consciousness worsened to Glasgow coma score 13/15. The MRI showed highly enhanced cranial and spinal leptomeninges and paquimeninges with a micro nodular-granulomatous aspect associated with intense affectation of basal cisterns, subarachnoid spaces and convexity of both cerebral hemispheres suggestive of leptomeningeal spread of the spinal mass. The patient expired after three days. CONCLUSION. Leptomeningeal spread is a rare phenomenon and when it happens usually doesn't change the primary tumor's behavior. In our case the aggressiveness could be explained by a potential malignization of the primary tumor that it was not documented because of the partial resections from the lasts surgeries or instead the tumor was actually a monomorphous pilomyxoid tumor.

ABSTRACT

BACKGROUND: Around 600 spinal epidural hematoma cases have been previously reported. Incidence of paraplegia after epidural anesthesia varies between 0,0005 and 0,02%. Several possible etiologies have been described in the literature, including surgery, trauma, anticoagulant therapy, arteriovenous malformations, pregnancy and lumbar puncture. Spinal and epidural anesthesic procedures represent the tenth most common cause. But in combination with anticoagulant therapy, the forementioned procedures increase its incidence until reaching the fifth most common etiological group. We report the case of an 80 year-old-man with a cervical epidural hematoma who had a good outcome with conservative management. CASE REPORT: 80 year-old-man that developed intense cervicalgia with lower limbs weakness showing complete paraplegia and arreflexia 2 hours after analgesic treatment with epidural cervical infiltration for cervicoartrosis. Cervical MRI showed epidural cervical hematoma between C4 and T1 levels. The patient is transferred to our facilities in order to perform surgery. But after showing fast recovery, medical conservative management was elected. After one month, the patient's condition has improved showing no neurological deficits and complete resorption is seen in MRI. CONCLUSIONS: Nowadays, trend is to perform surgery in patients with spinal hematoma and significant neurological deterioration during the first hours. However, good neurological outcomes can be achieved with conservative management, in well selected patients with non progressive, incomplete and partial deficits. Presently, we can not predict which is the best treatment for each case.

ABSTRACT

Quantifying the dissimilarity among two or more many-electron systems by means of their one-particle densities is a hot topic within the physical applications of the information theory. This is a relevant achievement of the so-called "divergence measures," for which several definitions have been considered, each one with its own advantages and difficulties. Nevertheless, all of them are considered in order to disclose the differences among the involved systems, neutral atoms in the present work, according to their densities in the position and momentum spaces. The pioneering Jensen-Shannon divergence (JSD) constitutes a particular case of the one-parameter Jensen-Tsallis divergence (JTD). The analysis here provided for the JTD of atomic systems generalizes and improves some previous results on the JSD one. Such an improvement mainly arises from the capability of JTD to modify, by means of its characteristic parameter, the relative contribution of relevant specific regions of the atomic densities in both conjugated spaces.

ABSTRACT

The Fisher divergence (FD) and Jensen-Shannon divergence (JSD) are used in this work with the aim of providing quantitative measures of the discrepancies between two arbitrary D-dimensional distribution functions, the FD being of local character and the JSD of global one. In doing so, the concepts of Fisher information and Shannon entropy associated to a distribution are the essential quantities for building up these comparative functionals. This kind of relative measures are here applied to the study of the one-particle densities in both conjugated spaces (position and momentum) of neutral atoms, discussing the results as compared to those provided by other previous functional measures. It is clearly shown how these divergences provide relevant information on the atomic shell structure, up to a level which depends on the considered space and measure.

ABSTRACT

PURPOSE: To evaluate the role and success rate of urethral reconstruction in patients with urethral stricture previously treated with thermos-expandable Memokath™ urethral endoprosthesis. MATERIALS AND METHOD: A case series of patients with urethral stricture and Memokath™ endoprosthesis treated with urethroplasty is presented. Reconstruction was decided due to stricture progression or complications derived from primary stent treatment. Age, stricture and stent length, time between stent placement and urethroplasty, mode of stent retrieval, type of urethroplasty, complications and voiding parameters before and after urethroplasty were evaluated. Successful outcome was defined as standard voiding, without need of any postoperative procedure. RESULTS: Eight cases with bulbar urethra stricture were included. Memokath™ was endoscopically retrieved before urethroplasty in 6 (75%) and by open urethrotomy at the time of urethroplasty in 2 (25%). Technique of urethroplasty was dorso-lateral onlay buccal mucosa graft in 5 (62.5%) cases and excision and primary anastomosis, anastomotic urethroplasty, and dorsal onlay buccal mucosa graft in one (12.5%) case each. There was no failure at 26±21.5 months median follow-up. Total IPSS, QoL, Qmax and postvoid residual significantly improved (P<.05). The only complication presented was epididymitis and penile shortening in one patient (12.5%). CONCLUSIONS: Urethroplasty after re-stricture or other complications in patients with temporary Memokath™ urethral stent is a viable and definite option of reconstruction with excellent results in the short term and few complications. One-side dorsolateral onlay buccal mucosa graft augmentation is the optimal technique for this indication.

ABSTRACT

Forestier's disease or diffuse idiophatic skeletal hyperostosis is a systemic reumathological abnormality of unknown etiology. It produces calcificationossification of the anterior longitudinal ligament. The low dorsal region is the most affected in the raquis. These patients are tipically asymptomatic or with few symptoms (minimal joint pain, spinal pain, stiffness). Dysphagia is the most common symptom when the disease affects the cervical spine; less frequent is dyspnea, both secondary to extrinsic compression of the esophagus and trachea. Neurological complaints are quite rare. In the 1970s Resnick described specific radiological criteria for the diagnosis of Forestier's disease that are still used today. It affects men more frequently than women (2:1); the peak occurrence is in patients in their 60s. We present two cases diagnosed by severe difficulty with deglution, a 84 years-old woman and a 54 years-old man; we operated on them for surgical decompression of the esophagus with resection of osteophytes C3-C4 and C5-C6 respectively through a conventional anterolateral neck approach. Relief of difficulty in swallowing was immediately ensued.

ABSTRACT

OBJECTIVE: To understand certain outstanding aspects of the life of the Basque surgeon and urologist Julián Guimón Rezola. His personal and bibliographic documentary legacy helps reconstruct his works and personal character. MATERIAL AND METHODS: We analysed the written works of Julián Guimón Rezola and a collection of documents, letters, photographs, illustrations and objects from his personal and professional life, accessed through his family. We analysed the content of the author's main publications and related the documents to historic facts. RESULTS: Julián Guimón Rezola was an upstanding individual, a father, a family man and a nationalist before the struggle, who was dedicated to his work and particularly to teaching and health management. He started his urological career under the direction of Francisco Pérez Andrés in the Santo Civil Hospital of Bilbao. He endured unjust repression for participating in the creation of the Basque University in 1936. Sentenced to life imprisonment, he stated a new life as a reclusive surgeon in the prison of Puerto de Santa María. He was pardoned three years later but was deprived of all his offices and disqualified from civil service. He founded his clinic and maintained his training in the United States. He presided over the Medical-Surgical Insurance Group of Bilbao (Igualatorio Médico-Quirúrgico) and, on 2 occasions, the Bilbao Academy of Medical Sciences. He was considerably active professionally and focused on social medicine and modern urology. He wrote 104 scientific articles, a number of which were of considerable quality and impact. We observed an evolution in the subject matter of these articles, all with exquisite professionalism and humanity. He corresponded with renowned practitioners and was admitted to the Spanish Royal National Academy of Medicine in 1970. He ended his career with an appointment as honorary professor at the University of the Basque Country 2 years before his death. CONCLUSIONS: Surgeon urologist Julián Guimón Rezola was a fundamental figure in Basque and Spanish medicine in the 20th century. He was the victim of a severe reprisal, not so much for political issues but rather for his institutional loyalty. However, he regained his professional and academic prestige. His written works reveal modern medicine with a considerable social foundation and the mind of a brilliant health manager.

ABSTRACT

OBJECTIVE: To describe the trends in the current management of urolithiasis in the Confederación Americana de Urología (CAU) setting to recognise patterns of clinical practice and identify educational needs. MATERIAL AND METHOD: An online survey was created with 31 multiple-choice questions (Spanish and Portuguese) through www.caunet.org, which revealed demographic data, patterns of clinical practice and approaches for specific clinical conditions. RESULTS: A total of 463 practitioners from Brazil, Mexico, Argentina, Spain, Colombia, Chile and other countries (3.96% of the members of CAU) completed the survey. All participants performed some type of urolithiasis treatment: 98.5% performed semirigid ureteroscopy (URS), 83.8% performed percutaneous nephrolithotomy (PCNL), 78.2% performed flexible URS, and 67.2% performed extracorporeal lithotripsy. The youngest physicians tended to perform PCNL (P<.001), and the proportion of users of flexible URS was greater in the Portuguese countries (P=.037). The main energy source was laser (60.7%). Small-calibre PCNL was performed by 15.3% of the respondents, more often in university hospitals (P<.01) and by older practitioners (P<.01). Only 3.2% of the respondents used percutaneous access to the kidney guided exclusively by ultrasound, especially the older practitioners (P<.001). The supine position was used by 40.4% of the respondents, more often in Spain (P<.001) and in the university setting (P=.017). PCNL without nephrostomy was practiced by 3.9% of the respondents. For flexible URS, 19.2% of the respondents did not use ureteral access sheaths, and the older practitioners preferred thinner calibre sheaths (P<.001). CONCLUSIONS: The management of lithiasis in the CAU setting follows a profile similar to that recognised in the European and American clinical guidelines, although there are interesting variations based on the practitioner's age and preferences. We identified potential areas for improvement in small-calibre PCNL and ultrasound-guided puncture.

ABSTRACT

OBJECTIVES: Feasibility study to evaluate efficacy and safety of Adjustable Transobturator Male System (ATOMS®) for male stress urinary incontinence (SUI) after transurethral resection of the prostate. MATERIALS AND METHODS: Twenty patients were implanted ATOMS® for SUI caused by transurethral resection of the prostate with or without radiotherapy. Incontinence severity was evaluated as mild (2 pads/day), moderate (3-5 pads/day) or severe (≥6pads/day), and dryness as none or one security pad/day. Changes in pad-test and pad-count after adjustment were investigated, together with operative parameters, patient satisfaction with the procedure, and number and grade of complications (Clavien-Dindo). RESULTS: Median age was 76.5years. Five patients received previous pelvic radiation (3 prostate, 2 rectal cancer) and 2 (10%) previous failed artificial urinary sphincter with urethral erosion and mechanical failure, respectively. Preoperative SUI was mild in 4 (20%), moderate in 7 (35%) and severe in 9 (45%). Median filling of the system was 13.5ml. Median pad-test decreased from 375±855ml baseline to 10±31.5ml and pad-count from 4±3 to 0±1.5 after adjustment (1±3fillings). Postoperative SUI distribution was mild in 2 (10%), moderate in one (5%) and severe in 2 (10%). Satisfaction rate was 80%, equal for transurethral resection of the prostate with/without previous radiotherapy. No patient had urinary retention after catheter removal. Complications presented in 3 (15%) patients, all minor. After median 38.5mo follow-up no system has been removed, 19 (95%) self-considered better than before and 11 (55%) very much better. CONCLUSION: Based on short-term efficacy and patient satisfaction ATOMS® can be considered a realistic alternative for SUI after transurethral resection of the prostate, even after irradiation. Absence of urethral erosion and very limited problems make this alternative especially attractive for cases with diminished dexterity, advanced age and previous failed treatments.

ABSTRACT

INTRODUCTION: Stress urinary incontinence (SUI) is a significant sequela of prostate cancer surgery. In this article, we present the surgical technique and safety and efficacy of the adjustable transobturator male system (ATOMS®) with preattached scrotal port. MATERIAL AND METHOD: An open prospective study was conducted at a university hospital with the main objective of changing the baseline condition after adjustment in the daily pad count and their wet weight (pad test). The secondary objectives were the quality-of-life assessment (International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF] and Incontinence Impact Questionnaire-7 [IIQ-7], baseline and after the adjustment), patient-perceived results (Patient Global Index [PGI] and Global Response Assessment [GRA] at 1 year) and assessment of complications according to Clavien-Dindo. The numerical values are expressed in median ± IQR. RESULTS: We analysed 60 consecutive patients with a follow-up of 21±22 months. The baseline pad-test was 465±450mL, and the pad-count was 5+3 pads/day. The baseline SUI was mild (11.6% of patients), moderate (25%) and severe (63.3%). The operative time was 60±25min, the hospital stay was 1±0 days, and the visual analogue scale of pain on day 1 after surgery was 0±1. The total filling was 16.5±7mL, and the number of refillings was 1±2. The pad-test and pad-count after the adjustment were 0±20mL and 0±1, respectively (both p<.0001 compared with baseline). SUI disappeared (81.7%) or remained mild (11.7%), moderate (5%) or severe (1.6%). We observed a reduction in the ICIQ-SF (p<.0001) and IIQ-7 scores (p=.0003). Both continence (p=.002) and satisfaction (p=.03) were lower in the irradiated patients. Complications occurred in 11 cases (18.6%), 8 (13.5%) of which were grade I and 3 (5.1%) of which were grade 3. The treatment satisfaction rate was 91.7%, and the patient-perceived overall improvement at 1 year was highly pronounced (PGI-I score, 1±1; GRA, 6±1). CONCLUSIONS: SUI treatment of men using third-generation ATOMS® is safe and effective in the short-term, even in patients with severe SUI. The rate of dry patients after the adjustment exceeded 80%, and the satisfaction rates exceeded 90%. The patients assessed this treatment highly positively.

ABSTRACT

INTRODUCTION: Laparoscopic radical cystectomy with lymphadenectomy and urinary diversion is an increasingly widespread operation. Studies are needed to support the oncological effectiveness and safety of this minimally invasive approach. PATIENTS AND METHODS: A nonrandomised, comparative prospective study between open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) was conducted in a university hospital. The main objective was to compare cancer-specific survival. The secondary objective was to compare the surgical results and complications according to the Clavien-Dindo scale. RESULTS: We treated 156 patients with high-grade invasive bladder cancer with either ORC (n=70) or LRC (n=86). The mean follow-up was 33.5±23.8 (range 12-96) months. The mean age was 66.9+9.4 years, and the male to female ratio was 19:1. Both groups were equivalent in age, stage, positive lymph nodes, in situ carcinoma, preoperative obstructive uropathy, adjuvant chemotherapy and type of urinary diversion. There were no differences between the groups in terms of cancer-specific survival (log-rank; P=.71). The histopathology stage was the only independent variable that predicted the prognosis. The hospital stay (P=.01) and operative transfusion rates (P=.002) were less for LRC. The duration of the surgery was greater for LRC (P<.001). There were no differences in the total complications rate (p=.62) or major complications (P=.69). The risk of evisceration (P=.02), surgical wound infection (P=.005) and pneumonia (P=.017) was greater for ORC. The risk of rectal lesion (P=.017) and urethrorectal fistulae (P=.065) was greater for LRC. CONCLUSION: LRC is an equivalent treatment to ORC in terms of oncological efficacy and is advantageous in terms of transfusion rates and hospital stays but not in terms of operating room time and overall safety. Studies are needed to better define the specific safety profile for each approach.

ABSTRACT

We present another case of delayed intracerebral hemorrhage after a ventriculoperitoneal (VP) shunting procedure. In this case, a right occipital intraparenchymal hematoma and associated intraventricular hemorrhage occurred six days after the operation for hydrocephalus secondary to subarachnoid hemorrhage in a 64 year old woman. It is a rare complication of VP shunting, with few cases reported previously in the literature. The presumed mechanism is the erosion of a cerebral blood vessel secondary to a close contact with the ventricular catheter; bleeding disorder, vascular malformation, head trauma or brain tumor were excluded in this patient.

ABSTRACT

OBJECTIVE: Quality graduate medical training is a concern of Confederación Americana de Urología (CAU), the third largest urological society worldwide. It is important to analyse the diversity in the state training programmes and the feasibility and implications of conducting a common CAU programme. MATERIAL AND METHODS: A 20-item questionnaire was distributed to the directors of national societies who are members of the CAU concerning the graduate urological training in their institutions. RESULTS: A total of 28 presidents and expresidents representing 21 countries responded, the total number of independent states that constitute the confederation. In this setting, 664 residents start their training programme every year, in an area that treats 645.4 million inhabitants, with an active professional force of 16,752 specialists. We present data on the realities of the training (length of the programme, core curriculum) and occupation (job access, possible flow between countries) and on how accreditation and re-certification of specialists in these countries are conducted. We also present the opinions on the feasibility of a joint CAU degree, as well as a number of its implications. CONCLUSIONS: The actual graduate training in the CAU setting is heterogeneous in its programmes and in its accreditation and re-certification methods. There is a strong desire to achieve joint degrees, except in Spain and Portugal. To enable joint certification, there will need to be intervention on numerous aspects and levels, redefining the desire for healthcare coverage in each country and considering the possible flow of specialists.
