Role of Renal Venous Oxygen Pressure for Renal Function Monitoring After Related Living-Donor Kidney Transplantation: Cohort Study.

BACKGROUND: Monitoring of renal function after kidney transplantation (KT) is performed by measuring serum creatinine (SCr), urine volumes (UV), and glomerular filtration rate (GFR). Other methods based on oxygen metabolism, such as the renal venous oxygen pressure (PrvO2), may be useful. The aim of this study was to explore the correlation between PrvO2 and SCr, UV, and GFR 5 days after KT (SCr5, UV5, and GFR5, respectively). METHODS: We conducted a prospective cohort study in adults scheduled for living donor KT. A venous blood sample was taken from the renal vein after declamping the renal artery, and blood gas determinations were made. Correlation analyses between PrvO2 and SCr5, UV5, and GFR5 were done by calculating Spearman's correlation coefficient with generalized linear models (GLM). A Spearman's correlation analysis was performed between the percentage decrease in SCr (%ΔSCr) and PrvO2. A GLM was also performed to determine the association of PrvO2 with slow graft function (SGF). RESULTS: The study included 42 patients, of whom 67% were men. The median age was 31 years (IQR, 27-43.5). PrvO2 was negatively correlated with SCr5 (ρ = -0.53, P = .003), and positively correlated with GFR5 (ρ = 0.49, P = .001) and %ΔSCr (ρ = 0.47, P = .002). A higher PrvO2 was associated with an increase in GFR in univariable (ß = 1.24, 95% CI, 0.56-1.93, P = .001) and multivariable (ß = 1.24, 95% CI, 0.53-1.94, P = .001) analyses. No association was found between PrvO2 and SGF. CONCLUSION: PrvO2 could be used to monitor renal function in the first 5 days after related living-donor KT, given its good correlation with SCr and GFR.

Remote visualization of large-scale genomic alignments for collaborative clinical research and diagnosis of rare diseases.

The Solve-RD project objectives include solving undiagnosed rare diseases (RD) through collaborative research on shared genome-phenome datasets. The RD-Connect Genome-Phenome Analysis Platform (GPAP), for data collation and analysis, and the European Genome-Phenome Archive (EGA), for file storage, are two key components of the Solve-RD infrastructure. Clinical researchers can identify candidate genetic variants within the RD-Connect GPAP and, thanks to the developments presented here as part of joint ELIXIR activities, are able to remotely visualize the corresponding alignments stored at the EGA. The Global Alliance for Genomics and Health (GA4GH) htsget streaming application programming interface (API) is used to retrieve alignment slices, which are rendered by an integrated genome viewer (IGV) instance embedded in the GPAP. As a result, it is no longer necessary for over 11,000 datasets to download large alignment files to visualize them locally. This work highlights the advantages, from both the user and infrastructure perspectives, of implementing interoperability standards for establishing federated genomics data networks.

CoDNaS-Q: a database of conformational diversity of the native state of proteins with quaternary structure.

SUMMARY: A collection of conformers that exist in a dynamical equilibrium defines the native state of a protein. The structural differences between them describe their conformational diversity, a defining characteristic of the protein with an essential role in multiple cellular processes. Since most proteins carry out their functions by assembling into complexes, we have developed CoDNaS-Q, the first online resource to explore conformational diversity in homooligomeric proteins. It features a curated collection of redundant protein structures with known quaternary structure. CoDNaS-Q integrates relevant annotations that allow researchers to identify and explore the extent and possible reasons of conformational diversity in homooligomeric protein complexes. AVAILABILITY AND IMPLEMENTATION: CoDNaS-Q is freely accessible at http://ufq.unq.edu.ar/codnasq/ or https://codnas-q.bioinformatica.org/home. The data can be retrieved from the website. The source code of the database can be downloaded from https://github.com/SfrRonaldo/codnas-q.

[Usefulness of the g8 questionnaire in predicting frailty in elderly patients with metastatic or castration-resistant prostate cancer.] / Utilidad de cuestionario G8 en la predicción de fragilidad en pacientes ancianos con cáncer de próstata metastásico o resistente a castración.

OBJECTIVE: to assess the capacityof the G8 questionnaire for the detection of frailty inpatients over 75 years of age with metastatic or castrationresistant prostate cancer and the relationshipof the results of this questionnaire with clinical variables,laboratory data, quality of life, functional statusand comorbidity. MATERIAL AND METHODS: Patients over the ageof 75 with metastatic or castration-resistant prostatecancer were evaluated using the G8 questionnaire.Those with a G8 15 were subjected to comprehensivegeriatric assessment in order to evaluate the abilityof this questionnaire to predict frailty. We studiedthe relationship between G8 score and functionalstatus (ECOG), comorbidity (Charlson index), qualityof life (FACT-P and EQ5D 3L questionnaires), diseasecharacteristics and common analytical variables. RESULTS: 64 patients were included in the study,of whom 26 scored 15 in the G8 questionnaireand were referred to geriatrics. 89% (23/26) of thepatients with a G8 score pre-fragile and 7 fragile) and only 11% (3/26) wereconsidered robust. The multivariate model showsthat the Charlson index and the EQ5D 3L score areindependent predictors of frailty. The Charlson index(OR=1.68, p=0.022) increases the probability thatthe patient has a G8 score the EQ5D-3L score (OR-0.64, p-0.021) decreases thatprobability. Both quantitative variables were recodedinto binary variables from the most predictivepoint obtained from the ROC curves and included ina model: patients with Charlson index ≥4 (OR=3.17,p=0.047) and those with EQ5D- 3L score (OR=3.35, p=0.037) increased the likelihood of obtaininga G8 scoreconditions (neither Charlson ≥4 nor EQ5D-3L score 15. However, the presence of the two conditions increasesthe probability to 71.5%. CONCLUSIONS: The score obtained in the G8questionnaire is a good predictor of frailty in elderlypatients with advanced prostate cancer. Comorbidity,as measured by Charlson's index, and quality of life,as measured by the EQ5D-3L questionnaire, are independentpredictors of frailty (score on the G8 questionnairebelow 15).

The European Genome-phenome Archive in 2021.

The European Genome-phenome Archive (EGA - https://ega-archive.org/) is a resource for long term secure archiving of all types of potentially identifiable genetic, phenotypic, and clinical data resulting from biomedical research projects. Its mission is to foster hosted data reuse, enable reproducibility, and accelerate biomedical and translational research in line with the FAIR principles. Launched in 2008, the EGA has grown quickly, currently archiving over 4,500 studies from nearly one thousand institutions. The EGA operates a distributed data access model in which requests are made to the data controller, not to the EGA, therefore, the submitter keeps control on who has access to the data and under which conditions. Given the size and value of data hosted, the EGA is constantly improving its value chain, that is, how the EGA can contribute to enhancing the value of human health data by facilitating its submission, discovery, access, and distribution, as well as leading the design and implementation of standards and methods necessary to deliver the value chain. The EGA has become a key GA4GH Driver Project, leading multiple development efforts and implementing new standards and tools, and has been appointed as an ELIXIR Core Data Resource.

CoDNaS-RNA: a database of conformational diversity in the native state of RNA.

SUMMARY: Conformational changes in RNA native ensembles are central to fulfill many of their biological roles. Systematic knowledge of the extent and possible modulators of this conformational diversity is desirable to better understand the relationship between RNA dynamics and function. We have developed CoDNaS-RNA as the first database of conformational diversity in RNA molecules. Known RNA structures are retrieved and clustered to identify alternative conformers of each molecule. Pairwise structural comparisons between all conformers within each cluster allows to measure the variability of the molecule. Additional annotations about structural features, molecular interactions and biological function are provided. All data in CoDNaS-RNA is free to download and available as a public website that can be of interest for researchers in computational biology and other life science disciplines. AVAILABILITY AND IMPLEMENTATION: The data underlying this article are available at http://ufq.unq.edu.ar/codnasrna or https://codnas-rna.bioinformatica.org/. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Repair of Traumatic Urethral Strictures: La Paz University Hospital Experience.

INTRODUCTION: The management of traumatic urethral strictures remains a challenge for urologists. Alteration of the pelvic anatomy and the significant fibrosis generated by the trauma make surgical repair complex. In most cases, the existing defect between the urethral ends is small, and the ideal treatment is end-to-end perineal urethroplasty. Cases of extensive strictures that are left with long gap defects may require the use of different sequential maneuvers to achieve a tension-free anastomosis. OBJECTIVE: To describe the experience at our center with urethral strictures induced by closed perineal trauma. MATERIALS AND METHODS: A retrospective analysis of 116 patients who underwent urethroplasty for urethral stricture after blunt perineal trauma at our center between 1965 and 2020 was conducted. Demographic data, date, mechanism of action of the trauma, emergency management, previous urethral interventions, surgical technique carried out in our center, complications, presence of erectile dysfunction, and urinary incontinence were collected. RESULTS: 82 patients (70.7%) presented with pelvic fractures. The most frequent etiology of trauma was traffic accidents (68%), followed by crushing injuries (24%). Suprapubic cystostomy was placed in 50.2% of patients, and urethral realignment was performed in 25.3%. The mean stricture length was 2.2 cm, affecting mostly the membranous urethra (67%). During surgery, it was necessary to perform crural separation in 61.5% and partial pubectomy in 18.8% of the cases. Erectile dysfunction developed after trauma in 40.5% of cases, while new erectile dysfunction was noted in 4.3% of patients after surgery. Surgery was successful in 91.3% of cases, with a median follow-up of 16 (6-47) months. CONCLUSION: Delayed anastomotic urethroplasty offers a high success rate in traumatic urethral strictures.

[Current status for urpper tract transitional cell carcinoma during COVID-19 pandemia.] / Situación actual de los tumores del tracto urinario superior en el contexto de la pandemia por Covid-19.

INTRODUCTION: First cases of COVID-19 were reported in China on December 2019 and rapidly spread globally. The explosive increase in number of cases requiring hospitalization has led to a delay in a big number of surgical interventions, including oncologic surgeries. Collateral effects of this increase means a challenge for urologists, who have been forced to redistribute their resources. Due to its poor pronostic, patients suffering from by upper tract urinary tumours will be negatively affected by this pandemic. METHODS: A non sistematic review was performed using literature published until May 23, 2020, using "Uppertract urothelial tumours", "COVID-19" and "nephroureterectomy".as keywords. The resulting manuscript was critically revised by national authors in order to establish common criteria about treatment and follow up. EVIDENCE SYNTHESIS: Four studies were identified that assessed the impact of delaying radical nephrouretrectomy as curative treatment. These studies showed that surgery delays decrease overall survival and cancer specific survival rates in high-risk groups. On the other hand, delaying radical nephrouretrectomy due to ureteroscopy did not affect survival in cohorts of patients with predominately low-grade disease. CONCLUSIONS: A delay in curative treatment of upper tract urothelial tumours for more than three months results in adverse outcomes as overal survival and cancer specific survival. Hence, it is important to prioritize the timely care of this group of patients as far as COVID-19 pandemic allows it.

INTRODUCCIÓN: Los primeros casos de la enfermedad por coronavirus (Coronavirus Disease 19, también denominada COVID-19) aparecieron en China en diciembre de 2019, desde donde se extendieron al resto del mundo. La rápida aparición de casos y el alto volumen de pacientes que han requerido hospitalización han provocado la demora de un gran número de intervenciones quirúrgicas, incluidas las cirugías oncológicas. Todo ello está suponiendo un reto para los servicios de urología de todo el mundo, y obliga a una redistribución de sus recursos. Los pacientes con tumores del tracto urotelial superior (TUS), en muchos casos de mal pronóstico, se pueden ver potencialmente afectadospor esta situación.MATERIAL Y MÉTODOS: Se realizó una búsqueda no sistemática en web y en PubMed utilizando las palabras clave "Upper tract urothelial tumours", "COVID-19" , "nephroureterectomy". Se realizó una revisión narrativa de la literatura incluyendo solo artículos y documentos escritos en lengua española e inglesa. Se remitió el documento a varios autores nacionales expertos en patología del urotelio superior, con el fin de unificar criterios y experiencias para llegar a un rápido consenso sobre la importancia relativa de las distintas actividades, problemas y soluciones. EVIDENCIA CIENTÍFICA: Diversos estudios tratan de determinar el impacto que presenta el retraso en la realización de la nefroureterectomía como tratamiento curativo, siendo el punto de corte de 3 meses en la mayoría de ellos. Tres de ellos concluyen que dicha demora implica una disminución de la supervivencia global y cáncer específica, mientras que el retraso de la nefroureterectomía radical debido a la realización de ureterorrenoscopia (URS) como tratamiento conservador en tumores de bajo grado no parece tener impacto en la supervivencia. CONCLUSIONES: El retraso en el tratamiento de los tumores del TUS a 3 meses supone una disminución de la supervivencia global y cáncer específica. Por ello, el tratamiento de esta patología no debería demorarse, en la medida en que los recursos hospitalarios y la alerta sanitaria por COVID-19 lo permita.

Revenant: a database of resurrected proteins.

Revenant is a database of resurrected proteins coming from extinct organisms. Currently, it contains a manually curated collection of 84 resurrected proteins derived from bibliographic data. Each protein is extensively annotated, including structural, biochemical and biophysical information. Revenant contains a browse capability designed as a timeline from where the different proteins can be accessed. The oldest Revenant entries are between 4200 and 3500 million years ago, while the younger entries are between 8.8 and 6.3 million years ago. These proteins have been resurrected using computational tools called ancestral sequence reconstruction techniques combined with wet-laboratory synthesis and expression. Resurrected proteins are commonly used, with a noticeable increase during the past years, to explore and test different evolutionary hypotheses such as protein stability, to explore the origin of new functions, to get biochemical insights into past metabolisms and to explore specificity and promiscuous behaviour of ancient proteins.

Treatment of posterior urethral distractions defects following pelvic fracture.

Posterior urethral injuries typically arise in the context of a pelvic fracture. Retrograde urethrography is the preferred diagnostic test in trauma patients with pelvic fracture where a posterior urethral rupture is suspected. Pelvic fractures however preclude the adequate positioning of the patient on the X-ray table on admission and computed tomography scan with intravenous contrast and delayed films generally performed first. Suprapubic bladder catheter placement under ultrasound guidance should be performed whenever a posterior urethral disruption is suspected. Early diagnosis and proper acute management decrease the associated complications, such as strictures, urinary incontinence and erectile dysfunction. The correct and appropriate initial treatment of associated urethral rupture is critical to the proper healing of the injury. Placing of a suprapubic cystostomy on admission and delayed anastomotic urethroplasty after 3-6 months continues to be the gold standard of treatment. In this paper, we provide a comprehensive review of the literature with a special emphasis on the various treatments available: Open or endoscopic primary realignment, immediate or delayed urethroplasty after suprapubic cystostomy, and delayed optical urethrotomy.

Limits of laparoscopic radical nephrectomy.

OBJECTIVES: Laparoscopic radical nephrectomy is considered to be the technique of choice in the management of stage T1 and T2 renal cancer, through increased expertise in this alternative type of surgery has served to expand its indications. In any case, these procedures have a series of limitations which are tied to the intrinsic characteristics of laparoscopic surgery, and associated with patient and tumor characteristics, and surgeon's expertise. METHODS: We performed a bibliographic review through Pub Med database. RESULTS: The present study discusses the different indications and establishes the current limits of laparoscopic surgery applied to the management of renal tumors (including T3 and T4). Its role in cell reducing therapy for metastatic disease, and the available methods to reduce tumor implantation in the surgical ports are also commented. CONCLUSIONS: Radical laparoscopic surgery is the technique of choice for the treatment of renal tumors in stage T1 and T2. There are not significant differences among the different approaches, and it has lower incision-related morbidity compared to traditional surgery, a shorter period of convalescence and the same oncological efficacy.

Límites de la nefrectomía radical laparoscópica / Limits of laparoscopic radical nephrectomy

OBJETIVO: Actualmente se considera la nefrectomía radical laparoscópica como la técnica de elección en el tratamiento del cáncer renal en estadios T1 y T2, aunque este tipo de alternativa quirúrgica ha ido ampliando sus indicaciones. De todas formas existen límites a este tipo de técnicas que van ligadas a la propia idiosincrasia de la laparoscópica; límites que están en relación con las características del paciente, las características del tumor y la experiencia del cirujano. MÉTODOS: Revisión bibliográfica mediante la base de datos de Pub Med. RESULTADOS: En este artículo se repasan las distintas indicaciones y se establecen los límites actuales de la cirugía laparoscópica en el tratamiento del tumor renal (incluidos T3 y T4), así como su papel en la terapia citoreductora en enfermedad metastásica. CONCLUSIONES: La cirugía laparoscópica radical es la técnica de elección para el tratamiento de los tumores renales en estadio T1 y T2. No existen diferencias significativas entre los distintos abordajes y presenta una menor morbilidad relacionada con la incisión, con respecto a la cirugía clásica, un período más corto de convalecencia y una misma eficacia oncológica(AU)

Molecular staging of prostatic cancer with RT-PCR assay for prostate-specific antigen in peripheral blood and lymph nodes. 5 Year follow-up

Objective: Thirty percent of patients with localized prostate cancer undergoing radical prostatectomy experience biochemical recurrence with rising serum prostate-specific antigen (PSA). More than 50% of these develop distant metastases. Methods: Presence of PSA mRNA in pathologically normal pelvic lymph nodes from 154 patients undergoing radical prostatectomy was investigated with non-quantitative PSA reverse transcriptase polymerase chain reaction (RT-PCR). In 135 of these patients preoperative serum PSA RT-PCR was also assessed. RT-PCR positivity was correlated with biochemical recurrence and compared with other clinical risk factors. Results: At a median follow-up of 58 months the biochemical failure-free survival of patients with positive versus negative lymph node RT-PCR was 68.4% and 76.7% respectively (p=0.2). Biochemical failure-free survival was not influenced by the serum PSA RT-PCR result either (72.3% versus 72.6%). Surgical margin status, preoperative serum PSA, pT category and Gleason score were independent prognostic risk factors for biochemical recurrence with a hazard ratio of 5.48, 2.56, 2.56 and 2.13 respectively. Conclusions: At 5 year follow-up after radical prostatectomy, both serum and lymph node RT-PCR are not correlated with biochemical failure-free survival. Established clinical risk factors have a much stronger impact on biochemical recurrence (AU)

Objetivo: El 30% de los pacientes con cáncer de próstata localizado sometidos a prostatectomía radical sufren recurrencia bioquímica con aumento del antígeno prostático específico (PSA). Más del 50% de ellos desarrollan metástasis a distancia. Métodos: Utilizando la prueba de reacción en cadena de polimerasa con transcriptasa inversa (RT-PCR) se investigó en 154 pacientes sometidos a prostatectomía radical la presencia de mRMA de PSA en ganglios linfáticos normales según el análisis anatomopatológico. En 135 pacientes también se evaluó la RT-PCR de PSA preoperatoria en sangre periférica. Se correlacionó un resultado positivo de RT-PCR con recurrencia bioquímica y se comparó con otros factores de riesgo clínicos. Resultados: La supervivencia libre de recurrencia bioquímica en los pacientes con RT-PCR positiva y negativa en ganglios linfáticos fue de 68,4% y 76,7% respectivamente (p = 0,2), con una mediana de seguimiento de 58 meses. El resultado de RT-PCR en suero no influyó en la supervivencia libre de recurrencia bioquímica en ninguno de los grupos (72,3% frente a 72,6%). El estado de los márgenes quirúrgicos, el PSA sérico preoperatorio, la categoría pT y el escore de Gleason fueron factores de riesgo independientes para el pronóstico de recurrencia bioquímica con un riesgo relativo de 5,48, 2,56, y 2,13 respectivamente. Conclusiones: Ni la RT-PCR de PSA sérica ni la de ganglios linfáticos se correlacionan con supervivencia libre de recidiva bioquímica a los cinco años de seguimiento después de prostatectomía radical. Factores de riesgo clínico establecidos tienen un impacto mucho más fuerte sobre la recurrencia bioquímica (AU)

Adverse events and readmissions after day-case urological surgery.

OBJECTIVE: The literature lacks of studies on postoperative outcomes after urological ambulatory surgery. Our study aims to identify parameters associated with postoperative complications within 30 days after ambulatory urological surgery. MATERIALS AND METHODS: Adjusted and unadjusted comparisons between clinical features and postoperative outcome (complicated and uncomplicated). RESULTS: Postoperative course was complicated in 5% of the patients. Discharge schedule was not completed in 1.1% while unplanned visits resulted in admission in 0.5%. Multivariate analyses could only confirm the independent effect of type of anesthesia and diagnosis-related group (DRG) relative weight. CONCLUSIONS: Ambulatory urological surgery can be safe in terms of postoperative complications. In the present study surgery under general anesthesia, or a higher DRG relative weight procedure, increased the risk of complications compared to surgery under regional or local anesthesia or lower DRG relative weight operations. Patients scheduled for general anesthesia or undergoing complex urological procedures should be warned about an increased risk of postoperative incidents and/or readmission.
