ABSTRACT
BACKGROUND: Acute kidney injury (AKI) is common among hospitalized patients with COVID-19 and associated with worse prognosis. The Spanish Society of Nephrology created the AKI- COVID Registry to characterize the population admitted for COVID-19 that developed AKI in Spanish hospitals. The need of renal replacement therapy (RRT) therapeutic modalities, and mortality in these patients were assessed MATERIAL AND METHOD: In a retrospective study, we analyzed data from the AKI-COVID Registry, which included patients hospitalized in 30 Spanish hospitals from May 2020 to November 2021. Clinical and demographic variables, factors related to the severity of COVID-19 and AKI, and survival data were recorded. A multivariate regression analysis was performed to study factors related to RRT and mortality. RESULTS: Data from 730 patients were recorded. A total of 71.9% were men, with a mean age of 70 years (60-78), 70.1% were hypertensive, 32.9% diabetic, 33.3% with cardiovascular disease and 23.9% had some degree of chronic kidney disease (CKD). Pneumonia was diagnosed in 94.6%, requiring ventilatory support in 54.2% and admission to the ICU in 44.1% of cases. The median time from the onset of COVID-19 symptoms to the appearance of AKI (37.1% KDIGO I, 18.3% KDIGO II, 44.6% KDIGO III) was 6 days (4-10). A total of 235 (33.9%) patients required RRT: 155 patients with continuous renal replacement therapy, 89 alternate-day dialysis, 36 daily dialysis, 24 extended hemodialysis and 17 patients with hemodiafiltration. Smoking habit (OR 3.41), ventilatory support (OR 20.2), maximum creatinine value (OR 2.41), and time to AKI onset (OR 1.13) were predictors of the need for RRT; age was a protective factor (0.95). The group without RRT was characterized by older age, less severe AKI, and shorter kidney injury onset and recovery time (pâ¯<â¯0.05). 38.6% of patients died during hospitalization; serious AKI and RRT were more frequent in the death group. In the multivariate analysis, age (OR 1.03), previous chronic kidney disease (OR 2.21), development of pneumonia (OR 2.89), ventilatory support (OR 3.34) and RRT (OR 2.28) were predictors of mortality while chronic treatment with ARBs was identified as a protective factor (OR 0.55). CONCLUSIONS: Patients with AKI during hospitalization for COVID-19 had a high mean age, comorbidities and severe infection. We defined two different clinical patterns: an AKI of early onset, in older patients that resolves in a few days without the need for RRT; and another more severe pattern, with greater need for RRT, and late onset, which was related to greater severity of the infectious disease. The severity of the infection, age and the presence of CKD prior to admission were identified as a risk factors for mortality in these patients. In addition chronic treatment with ARBs was identified as a protective factor for mortality.
ABSTRACT
INTRODUCTION: X-linked intellectual developmental disorder is clinically and genetically heterogeneous. The ubiquitin specific peptidase 27 X-linked gene (USP27X) has been associated with X-linked intellectual developmental disorder, and only 17 affected males have been described in the literature to date. CASE REPORT: A 6-year-old boy was assessed due to intellectual developmental disability, language delay, behavioural disorder, microcephaly and particular features. His mother had learning difficulties and a facial phenotypic overlap. A maternal uncle had an intellectual developmental disorder. Physical examination revealed an unusual phenotype (triangular facies, long palpebral fissures and eyelashes, medially eyebrow loss, prominent auricles), mild brachydactylia and hypoplasia in the distal phalanges. The clinical exome identified the probably pathogenic variant NM_001145073.3: c.692delT in the USP27X gene. The results of the family segregation analysis were positive: the mother and maternal uncle were harbourers, while healthy maternal aunt was not. CONCLUSIONS: We present two new cases of X-linked intellectual developmental disorder due to a previously unreported variant in the USP27X gene. Both patients presented neurological symptoms without any significant involvement at other levels, according to the literature. One of the cases presented microcephaly, particular features and digital anomalies, which broadens the phenotypic spectrum of this disease.
TITLE: Dos nuevos casos de discapacidad intelectual ligada al cromosoma X tipo 105 por variante patógena en el gen USP27X no descrita previamente.Introducción. La discapacidad intelectual ligada al cromosoma X es un trastorno clínica y genéticamente heterogéneo. El gen de la proteasa 27 específica de la ubiquitina ligada al cromosoma X (USP27X) se ha asociado a discapacidad intelectual ligada al cromosoma X, y en la actualidad sólo se ha descrito a 17 varones afectos en la bibliografía. Caso clínico. Niño de 6 años valorado por discapacidad intelectual, retraso del lenguaje, trastorno de la conducta, microcefalia y rasgos particulares. Madre con dificultades de aprendizaje y fenotipo facial solapante. Un tío materno con discapacidad intelectual aislada. En la exploración física destaca un fenotipo peculiar (facies triangular, fisuras palpebrales y pestañas largas, cejas menos pobladas medialmente, pabellones auriculares prominentes), leve braquidactilia e hipoplasia de falanges distales. El exoma clínico identificó la variante probablemente patógena NM_001145073.3: c.692delT en el gen USP27X. El estudio de segregación familiar fue positivo: madre y tío materno portadores, tía materna sana no portadora. Conclusiones. Describimos dos nuevos casos con discapacidad intelectual ligada al cromosoma X por variante no descrita previamente en el gen USP27X. Ambos pacientes presentan clínica neurológica sin afectación significativa a otros niveles de acuerdo con la bibliografía. Uno de los casos asocia microcefalia, rasgos particulares y anomalías digitales, lo que permite ampliar el espectro fenotípico de esta enfermedad.

OBJECTIVE: To analyse the efficacy of integrated assessment of [18F]F-PSMA-1007 PET/MRI on the early detection of local recurrence (LR) for prostate cancer patients with PSA levels <0.5ng/ml after radical prostatectomy. To assess the location of recurrence so that therapy may be tailored to patient. METHODS: Prospective study including 35 patients with prostate cancer (PCa), who were referred for a [18F]F-PSMA-1007 PET/MR after prostatectomy with a very initial PSA value increase (PSA<0,5ng/ml). Simultaneous acquisition in a PET/MRI hybrid equipment (SIGNA-GE), 1h after administration of 370%±10% MBq of [18F]F-PSMA-1007: Prostate selective imaging (20min): multiparametric PET+MRI (MRImp): DIXON, T1, T2, diffusion sequences post-gadolinium administration. Whole body image (30min): PET+MRI: DIXON, T1, T2, diffusion, STIR sequences. A nuclear physician and a radiologist jointly reviewed the studies: In order to assess LR, the "Prostate Imaging for Recurrence Reporting" system was used on MRI, as well as the Likert scale on the PET prostate imaging. The remaining lesions were classified as N1 and M1a. RESULTS: PET/MRI was positive in 25 patients (71,4%) and negative in 10 patients (28,6%). RL was detected in 15 patients (42.9%): in 2 (5.7%) MRI was superior; in 3 (8.6%) PET was superior; integrated PET/MRI showed improved results in 5 patients (14.3%) for the detection of LR. Location of recurrences: LR in 11 patients (44.0%); N1 in 10 (40.0%); LR+N1 (8.0%) in 2; LR+N1+M1a in 2 (8.0%). In 20 patients (80%) the PET/MRI findings allowed radioguided radiotherapy implementation (11 on LR, and 9 on N1), whereas hormonal treatment was decided in 5 patients (20%) due to multimetastases/spread disease. CONCLUSION: [18F]F-PSMA-1007 PET/MRI has a 71.4% recurrence detection rate after prostatectomy with PSA<0.5ng/ml. Its combined PET and MRI study increases the detection of LR by 14.3%, with a high N1+M1a detection rate (56%), allowing radioguided radiotherapy in 80% of patients.
ABSTRACT
EBV+ diffuse large B cell lymphoma (DLBCL) not otherwise specified (NOS) is a new entity confirmed by the World Health Organization (WHO) in 2017. In this new entity, the virus may contribute to a tolerogenic microenvironment. Traces of the virus have been described in DLBCL with more sensitive methods, in cases that were originally diagnosed as negative. The aim of this study was to analyze the expression of immune response genes in the tumor microenvironment to disclose the role of the virus and its traces in DLBCL. In 48 DLBCL cases, the expression of immune response genes and the presence of molecules that induce tolerance, such as TIM3, LAG3 and PDL1 by immunohistochemistry (IHC), were studied. To broaden the study of the microenvironment, tumor-associated macrophages (TMAs) were also explored. No significant differences were observed in the expression of immune response genes in the EBV+ DLBCL and those cases that were EBV- DLBCL but that exhibited viral traces, assessed by ViewRNA assay. Only the EBV+ DLBCL cases displayed a significantly higher increase in the expression of CD8 and cytotoxic T cells detected by gene expression analysis, and of PDL1 in tumor cells and in the expression of CD68 in the tumor microenvironment detected by IHC, not observed in those cases with viral traces. The increase in CD8 and cytotoxic T cells, PDL1 and CD68 markers only in EBV+ DLBCL may indicate that traces of viral infection might not have influence in immune response markers.

Introducción Los fármacos biológicos inhibidores del factor de necrosis tumoral (TNF) alfa son usados para tratar diferentes enfermedades inflamatorias. A pesar de su adecuado perfil de seguridad, se han descrito reacciones paradójicas asociadas a estos tratamientos. Material y método Se ha realizado una revisión retrospectiva de los pacientes en tratamiento con un anti-TNF que hubiesen presentado una reacción paradójica con afectación cutánea visitados en el Servicio de Dermatología del Hospital Universitari Parc Taulí de Sabadell. Resultados Registramos 30 pacientes en tratamiento con un anti-TNF que desarrollaron un efecto adverso cutáneo inmunomediado en forma de psoriasis (90%), alopecia (6,7%) o dermatitis neutrofílica (3,3%). Adalimumab fue el fármaco más implicado (56,7%), seguido de infliximab (40%). La morfología de la reacción psoriasiforme más descrita es la generalizada en placas (62,9%), seguida de la pustulosis palmo-plantar (37%). El 43,3% de los pacientes mantuvieron el anti-TNF, y de ellos el 92,3% obtuvieron una resolución total y parcial. De los 5 pacientes que iniciaron otro anti-TNF, ninguno obtuvo una resolución total. De los 8 pacientes que cambiaron a un tratamiento biológico diferente al anti-TNF, el 62,5% obtuvieron una resolución total o parcial. Discusión La aparición de una reacción paradójica no siempre obliga al cambio de tratamiento biológico, puesto que se ha observado la resolución de las lesiones cutáneas con un tratamiento tópico y/o sistémico adicional en más de la mitad de los pacientes, sin necesidad de suspender el anti-TNF. Si la afectación es grave, se debe plantear el cambio de tratamiento biológico, siendo más eficaz iniciar un fármaco dirigido a una diana terapéutica distinta al anti-TNF (AU)
Background Tumor necrosis factor α (TNF) inhibitors are used to treat different inflammatory diseases. Although these biologics have an adequate safety profile, they have been associated with paradoxical reactions. Material and methods Retrospective review of patients on TNF inhibitor therapy who developed a paradoxical skin reaction and were seen at the dermatology department of Hospital Universitari Parc Taulí in Sabadell, Spain. Results We collected data on 30 patients under treatment with a TNF inhibitor who developed an immune-mediated skin reaction in the form of psoriasis (90%), alopecia (6.7%), or neutrophilic dermatitis (3.3%). The most common drugs involved were adalimumab (56.7%) and infliximab (40%). Psoriasiform reactions mostly manifested as generalized plaques (62.9%) or palmoplantar pustulosis (37%). Thirteen patients (43.3%) continued on the same TNF inhibitor and 12 of them (92.3%) achieved partial or complete resolution of lesions. Five patients were switched to a different TNF inhibitor, but none of them achieved complete resolution. Eight patients were switched to a biologic with a different target, and 5 of them (62.5%) achieved partial or complete resolution. Conclusions Paradoxical reactions during TNF inhibitor therapy do not always require a change of treatment. In our series, the addition of a topical and/or systemic treatment resolved the skin lesions in more than half of the patients, and switching to a drug with a different target was more effective. A change of strategy should be contemplated in more serious cases (AU)

Objetivos: Analizar la influencia de trazodona en la mortalidad de pacientes en tratamiento con digoxina. Material y métodos: Estudio observacional retrospectivo comparativo de mortalidad de pacientes en tratamiento concomitante con digoxina y trazodona versus digoxina. El período de estudio fue de un año (1 de mayo de 2020 hasta 30 de abril de 2021). Las variables recogidas fueron edad, sexo, indicación, dosis de digoxina y trazodona, fecha de inicio de trazodona, fecha fin de digoxina y trazodona, número total de fármacos prescritos, éxitus y fecha de éxitus. El análisis estadístico se realizó mediante la aplicación Stata®. Versión 14.2. Resultados: Se incluyeron 644 pacientes en tratamiento con digoxina, 73 en el grupo con trazodona y 571 en el grupo sin trazodona. Al final del periodo estudiado se registraron 73 muertes, observándose una mortalidad del 34,3% en el grupo de digoxina y trazodona, y del 8,4% en el grupo de digoxina. Las variables relacionadas con el riesgo de muerte fueron tratamiento con tradozona, edad y número de tratamientos prescritos. Conclusiones: Los resultados del estudio sugieren un incremento del riesgo de mortalidad en pacientes de edad avanzada en tratamiento con digoxina y trazodona. La falta de evidencia de uso de trazodona como hipnótico, la interacción farmacocinética entre ambos fármacos y el perfil de seguridad de trazodona, hace necesario una estrecha monitorización de los pacientes o valorar alternativas con mayores evidencias de seguridad.(AU)
Objectives: To evaluate the trazodone influence on the mortality of patients treated with digoxin. Material and methods: Retrospective, observational, comparative study that included patients receiving trazodone and digoxin concomitantly and patients on digoxin treatment without trazodone between April 2020-April 2021. Age, sex, drug indication, digoxin and trazodone dosage, start and end dates of trazodone use, digoxin end date, number of prescribed drugs and death date were the variables we paid attention to. Statistical analysis was performed using the Stata® application. Version 14.2. Results: 644 patients were included, 73 in the group digoxin with trazodone and 571 in the group without trazodone. At the end of the study period, 73 deaths were recorded. Mortality in the digoxin and trazodone group were 34.3% and 8.4% in the digoxin group. The variables related to the risk of death were treatment with trazodone, age and number of prescribed treatments. Conclusions: The results of the study suggest an increased risk of mortality in elderly patients in treated with digoxin and trazodone. The lack of evidence in the use of trazodone as a hypnotic, the pharmacokinetic interaction between both drugs and the safety profile of trazodone, makes it necessary to closely monitor patients or assess therapeutic alternatives with more evidence to be sure its use is safe.(AU)

Introducción Los trastornos temporomandibulares son la causa más común de dolor crónico orofacial. Intervenciones pasivas como la terapia manual (TM) es de las herramientas más utilizadas. Sin embargo, este tipo de abordajes puede resultar insuficiente. La investigación de nuevas estrategias, ahora de naturaleza activa, como son el ejercicio o la educación, es necesaria para generar un cambio en la práctica clínica de los profesionales sanitarios y brindar una atención completa al paciente con dolor crónico. Objetivos Analizar el efecto de tres abordajes principales de forma combinada sobre el dolor, factores psicosociales, variables funcionales y biomecánicas. Métodos Se siguió un diseño de estudio de casos compuesto por tres sujetos divididos en tres modelos de intervención: educación para el dolor y terapia manual (PEdu+TM), ejercicio terapéutico y terapia manual (PEjerc+TM) y terapia manual cervical y orofacial (PTM). El periodo de intervención duró 3-4 semanas; las medidas fueron tomadas en tres momentos: preintervención, postintervención inmediata y 45 días postintervención. Dolor, características psicosociales y funcionalidad del paciente fueron evaluadas con diferentes herramientas validadas. Resultados Los resultados mostraron a corto plazo una mejora en todas las variables analizadas en el PEdu+TM y en el PEjerc+TM, pero no en el PTM. A medio plazo (45 días postintervención), el PEdu+TM mostró beneficios en todas las variables estudiadas mientras que el PEjerc+TM generó cambios positivos en las mismas variables excluyendo el dolor. Conclusión El tratamiento combinado podría ser una intervención más eficaz que la terapia manual a solas, siendo necesarios ensayos clínicos aleatorizados que corroboren dichos hallazgos (AU)
Introduction Temporomandibular disorders are the most common cause of chronic orofacial pain. Passive interventions such us manual therapy (MT) is being one of the most used tools. However, this type of approach may be insufficient. The investigation of new strategies, now of an active nature such as exercise or education, it is necessary to generate a change in the clinical practice of health professionals and provide comprehensive care to patients with chronic pain. Objectives To analyze the effect of three main approaches in combination on pain, psychosocial factors, functional and biomechanical variables. Methods A case study design was followed consisting of three subjects divided into three intervention models: pain education and manual therapy (PEdu+TM), therapeutic exercise and manual therapy (PExer+TM), and cervical and orofacial manual therapy (PTM). The intervention period lasted 3-4 weeks, the measurements were taken at three moments: pre-intervention, immediate post-intervention and 45 days post-intervention. Pain, psychosocial characteristics and functionality of the patient were evaluated with different validated tools. Results The results showed in the short-term an improvement in all the variables analyzed in the PEdu+TM and in the PExer+TM, but not in the PTM. In the medium term (45 days post-intervention), the PEdu+TM showed benefits in all the variables studied, while the PExer+TM generated positive changes in the same variables, excluding pain. Conclusion Combined treatment could be a more effective intervention than manual therapy alone, requiring randomized clinical trials to corroborate these findings (AU)

Introducción: La administración intravenosa de fluidos constituye un elemento fundamental en la reanimación de pacientes con hipovolemia. Las guías clínicas restringen el uso de coloides en favor de los cristaloides. Actualmente, no conocemos con exactitud cuál es la práctica clínica habitual al respecto durante el periodo perioperatorio. El objetivo del presente estudio es describir el uso perioperatorio de coloides y analizar las posibles causas que motivan su utilización. Material y métodos: Estudio observacional, transversal, multicéntrico. Subanálisis del estudio Fluid Day. Se incluyeron todos los pacientes mayores de 18 años sometidos a cirugía durante las 24h de los 2 días del estudio (18 y 20 de febrero de 2019). Se registraron datos demográficos, comorbilidades, datos referentes al acto anestésico y el procedimiento quirúrgico, fluidos administrados, sangrado perioperatorio y tipo de monitorización utilizado durante el periodo perioperatorio. Resultados: Se analizaron 5.928 casos. Un total de 542 pacientes (9,1%) recibieron algún tipo de coloides, siendo el hidroxietilalmidón el más utilizado (5,1%). Los pacientes que recibieron coloides tuvieron intervenciones más prolongadas (150 [90-255] vs. 75 [45-120] min), fueron intervenidos de urgencia (13,7 vs. 7,5%) y se clasificaron como de alto riesgo (22 vs. 4,8%) más frecuentemente. Su recuperación inmediata mayoritariamente transcurrió en unidades de críticos (45,1 vs.15,8%). Los pacientes que presentaron una hemorragia menor de 500ml recibieron coloides en un 5,9% frente al 45,9% cuando se superó esta cifra. Los pacientes que recibieron coloides presentaban anemia más frecuentemente: 29,4 vs. 16,3%. La administración de coloides supuso un mayor riesgo de transfusión (OR 15,7). La monitorización avanzada también aumentó la probabilidad de administrar coloides (OR 9,43). Conclusiones: En nuestro medio y en condiciones de práctica clínica habitual, la utilización de los coloides es escasa...(AU)
Introduction: Fluid administration is the cornerstone in hypovolemic patient's reanimation. Clinical guidelines restrict colloid administration favouring crystalloids. Currently, we dont know exactly which is the daily clinical practice during the perioperative period. The objective of this study is to describe perioperative use of colloids analysing possible reasons aiming to use them. Material and Methods: Prospective, cross-section, national, multicentre observational study. Fluid Day sub-study. We enrolled all patient's older than 18 years old who underwent surgery during the 24h of the 2-days study (February, 2019, 18th and 20th). We registered demographic data, comorbidities, anaesthetic and surgical procedure data, fluids administered, perioperative bleeding and monitoring type used during the perioperative period. Results: A total of 5928 cases were analysed and 542 patients (9.1%) received any type of colloids, being hydroxiethyl-starch the most frequently used (5.1%). Patients receiving colloids suffered more longing surgery (150 [90-255] vs. 75 [45-120] min), were urgently operated (13.7 vs. 7.5%) and were more frequent classified as high risk (22 vs. 4.8%). Their recovery was mostly in critical care units (45.1 vs.15.8%). Patients with bleeding less than 500mL received colloids in a percentage of 5.9 versus 45.9% when this figure was overcome. Patients who received colloids were anaemic more frequently: 29.4 vs. 16.3%. Colloids administration had a higher risk for transfusion (OR 15.7). Advanced monitoring also increased the risk for receiving colloids (OR 9.43). Conclusions: In our environment with routine clinical practice, colloids administration is limited and close linked to perioperative bleeding.(AU)

La hipertensión arterial maligna se define por cifras extremadamente altas de presión arterial asociadas a daño orgánico. Constituye una causa de emergencia hipertensiva donde coexisten cifras elevadas de presión arterial, con hemorragia y exudados bilaterales retinianas (retinopatía hipertensiva grado III), con o sin papiledema (retinopatía hipertensiva grado IV), asociada usualmente a lesión renal o cardíaca. En un 1% de los casos es secundaria a causas endocrinológicas, entre ellas, la más frecuente: el feocromocitoma, que clásicamente se ha caracterizado por la tríada cefalea, sudoración y palpitaciones. Sin embargo, no existe un hallazgo clínico único que tenga un valor significativo en su diagnóstico. A continuación, presentamos el caso de una paciente de 23 años con emergencia hipertensiva y masa suprarrenal asociado a retinopatía hipertensiva grado IV. (AU)
Malignant arterial hypertension is defined by extremely high levels of pressure associated with organ damage. It is a cause of hypertensive emergency and is defined by the coexistence of high blood pressure and bilateral retinal haemorrhage or exudates (grade III hypertensive retinopathy), with or without papilloedema (grade IV hypertensive retinopathy) currently associated with organ damage such as renal or cardiac failure. Around 1% of malignant arterial hypertension is secondary to endocrinological causes, including the most common: pheochromocytoma, which is classically characterized by the triad: headache, sweating and palpitations. However, there is no single clinical finding that is of significant value in its diagnosis. We now present the case of a 23-year-old patient with a hypertensive emergency, an adrenal mass associated with grade IV hypertensive retinopathy. (AU)

El sistema renina-angiotensina-aldosterona (SRAA) y sus efectos en el flujo sanguíneo e hidrosalino han sido estudiados a nivel cardiovascular y renal. La activación del SRAA en otros órganos tiene efectos tanto locales como sistémicos, alterando la macro y microvascultura de los órganos periféricos. En el cerebro, el SRAA regula la presión arterial (PA) a través del sistema nervioso simpático. El eje enzima convertidora de angiotensina/angiotensina II/receptor de angiotensina 1 (ECA/Ang II/AT1), vía clásica, y enzima convertidora de angiotensina tipo 2/angiotensina (1-7)/receptor Mas (ECA2/Ang [1-7]/MasR), vía no clásica, modulan la respuesta simpática. Su descompensación y acumulación de Ang II propician la hipertensión neurogénica (HTN) y otras patologías vasculares. El eje aminopeptidasa/angiotensina IV/receptor de angiotensina 4 (AMN/Ang IV/AT4), exclusivo del cerebro, condiciona la microvasculatura cerebral e interviene en la cognición, la memoria y el aprendizaje. Esta revisión propone descifrar los mecanismos de regulación de la PA por el SRAA central, así como revisar sus funciones y su contribución en la neuroprotección y la cognición. (AU)
The renin-angiotensin-aldosterone (RAAS) system and its effects on blood pressure and the regulation of water and electrolyte balance have been studied focusing on the cardiovascular and renal system. The activation of RAAS in other organs has local and systemic repercussions by modeling the macro- and microvasculture of peripheral organs. The brain RAAS influence on systemic blood pressure through the sympathetic nervous system. The angiotensin converting enzyme/angiotensin II/angiotensin 1 receptor axis (ACE/AngII/AT1), classical pathway, and angiotensin converting enzyme type 2/angiotensin (1-7)/Mas receptor (ACE2/Ang (1-7)/MasR), non-classical pathway, are involved in the modulation of the sympathetic response. The imbalance of these two axes with subsequently Ang II accumulation promote neurogenic hypertension and other vascular pathologies. The aminopeptidase/angiotensin IV/angiotensin 4 receptor (AMN/Ang IV/AT4) axis, which is exclusive of the brain, acts on cerebral microvasculature and participates in cognition, memory, and learning. The aim of this review is to decipher the major central RAAS mechanisms involved in blood pressure regulation. In addition, paracrine functions of brain RAAS and its role in neuroprotection and cognition are also described in this review. (AU)

OBJETIVO: Evaluar la tasa de detección de la PET/RM con 18F-colina y los cambios en el manejo terapéutico de los pacientes con cáncer de próstata tratados con prostatectomía que presentan elevación del PSA <1 ng/ml. MÉTODO: Estudio prospectivo de los 36 primeros pacientes con cáncer de próstata tratados con prostatectomía, con elevación de PSA<1 ng/ml, a los que hemos realizado una PET/RM con 18F-colina. Tras la administración de 185±10% MBq de 18F-colina se ha adquirido un estudio en dos fases: 1) precoz prostática (inmediatamente tras la administración del trazador): emisión PET/RM multiparamétrica. 2) Estudio una hora postinyección de cuerpo completo: emisión PET/RM: T1, T2, STIR, difusión. El comité oncológico ha decidido la estrategia terapéutica de los pacientes según los hallazgos de la PET/RM con 18F-colina. RESULTADOS: De los 36 pacientes, 20 (55,6%) han mostrado positividad del estudio PET/RM con 18F-colina: en 8 (22,2%) lecho de prostatectomía, en 7 (19,4%) adenopatías infradiafragmáticas, en 4 (11,1%) recidiva local y adenopatías infradiafragmáticas, en 1 (2,8%) una metástasis ósea. De los 36 pacientes, en 16 (44,4%) el estudio PET/RM con 18F-colina ha sido negativo. Los hallazgos de la PET/RM con 18F-colina han condicionado la estrategia terapéutica: en 15 pacientes (41,6%) enfermedad oligometastásica tratada con radioterapia guiada por la imagen, en 5 (13,9%) enfermedad multimetastásica tratada con privación androgénica, en 16 (44,4%) negativo en vigilancia activa. CONCLUSIÓN: La técnica híbrida PET/RM con 18F-colina ha demostrado una elevada tasa de detección de la recidiva en los pacientes tratados con prostatectomía que presentan PSA <1 ng/ml, permitiendo una estrategia terapéutica personalizada según los hallazgos de la exploración
OBJECTIVE: To assess the detection rate of 18F-Choline PET/MRI and subsequent changes in therapy approach for patients with prostate cancer treated by prostatectomy and with rising levels of PSA <1 ng/ml. METHODS: Prospective study with our first 36 patients with prostatectomy for prostate cancer and rising levels of PSA, who were referred for an 18F-Choline PET/MRI study. A dual-phase study was acquired after intravenous administration of 185±10% MBq of 18F-Choline: 1) early imaging (immediately after tracer administration) of prostate area (emission PET/Multiparametric MRI). 2) whole-body imaging 1 h after tracer injection (emission PET/MRI: T1, T2, STIR, diffusion). The therapy approach for patients was decided upon the Oncology Committee consensus based on 18F-Choline PET/MRI findings. RESULTS: Twenty out of 36 patients (55.6%) were positive for the 18F-Choline PET/MRI study: 8 (22.2%) within the prostatectomy bed, 7 (19.4%) with infradiaphragmatic lymph nodes, 4 (11.1%) with local recurrence and infradiaphragmatic lymph nodes, and 1 (2.8%) with bone metastasis. Sixteen out of the 36 patients (44.4%) were negative for the 18F-Choline PET/MRI study. 18F-Choline PET/MRI findings had an impact on the therapy approach to follow: 15 patients (41.6%) showed oligometastatic disease which was treated by imaging-guided radiotherapy, 5 (13.9%) with multiple metastatic disease were treated by androgen deprivation therapy, 16 (44.4%) negative were under active surveillance. CONCLUSION: Hybrid 18F-Choline PET/MRI procedure showed a high detection rate for recurrence in prostate cancer patients treated with prostatectomy and rising PSA levels <1 ng/ml, and 18F-Choline PET/MRI findings resulted in a better tailored therapy approach delivered to our patients

INTRODUCCIÓN: Estandarizar los protocolos de adquisición de 18F-Colina PET/TC, que permitan evitar la interferencia urinaria, evaluar el mejor tiempo del estudio de cuerpo completo y valorar si la «doble fase» permite la diferenciación entre lesiones benignas frente a malignas. MÉTODO: Estudio prospectivo que incluye 100 pacientes con cáncer de próstata: 31 estadificación y 69 recidiva bioquímica (32 posprostatectomía y 37 posradioterapia). Adquisición pélvica inmediatamente tras inyección de 18F-Colina y estudio de cuerpo completo, 1 y 2h p.i. Cálculo de media SUVmáx por territorios en todos los estudios secuenciales. Análisis de medias (χ2) y porcentaje de cambio del SUV (2/1h; 1h/0min). Patrón de dinámica metabólica: acumulativo frente a aclaramiento. Seguimiento tras tratamiento en todos los pacientes y de forma dirigida, cuando éticamente es posible. RESULTADOS: Cincuenta y tres focos prostáticos, en ninguna de las imágenes precoces actividad urinaria: Patrón acumulativo en 42, porcentaje de aumento: 0min/1h: +16,7% (X20,94); 1/2h: +10,0% (X20,83). Patrón aclaramiento en 11, porcentaje de reducción: 0min/1h: 21,4% (X20,91); 1/2h: −7,7% (X20,85), correspondiendo en 7 a estadificación y 4 a posradioterapia. Todos los focos infradiafragmáticos (n: 24) mostraron dinámica acumulativa, porcentaje de aumento: +9,1% (χ20,97), todas ellas visibles en el primer estudio. De los 12 focos supradiafragmáticos, 8 mostraron aclaramiento, porcentaje de reducción: −13,0% (χ2 0,95). Los otros 4 dinámica acumulativa, porcentaje de aumento: +13,0% (χ2 0,96), siendo valorados invasivamente. Todos los focos óseos (n: 18) mostraron dinámica acumulativa, porcentaje de aumento: +17,1% (χ20,95), todas ellas visibles en el estudio 1h. CONCLUSIONES: En la valoración prostática la mejor técnica doble fase es 0min/1h. En la diferenciación de adenopatías supradiafragmáticas es aconsejable la técnica de doble fase: 1/2h. Para la infiltración infradiafragmática y ósea, ante hallazgos dudosos, las imágenes 2h aumentan la confianza diagnóstica
AIM: To standardize acquisition protocols for 18F-Choline PET/CT to prevent from urine interference, to determine the best time point for the whole-body study, and to assess whether "dual point" acquisition allows for differentiating malignant vs. benign lesions. METHODS: One hundred consecutive patients with prostate cancer were prospectively studied. Immediately after 18F-Choline injection, a pelvis study was acquired, and a whole-body was subsequently obtained 1 and 2 hours p.i. Mean SUVmax was obtained in regions and for every sequential imaging. Mean analysis (χ2) and SUV percentage change (2/1 hours; 1 hours/0 min) were obtained. Metabolic pattern dynamics were assessed: accumulative vs. clearance. Patient follow-up after therapy and directed classification whenever ethically possible were performed. RESULTS: Fifty-three prostate foci, without disturbing urinary activity was ever found on early images. Accumulative pattern in 42, with percentage increase was: 0 min/1 hour: +16.7% (χ20.94); 1/2 hours: +10,0% (χ2 0.83). Clearance pattern in 11, with percentage decrease: 0 min/1 hour: −21.4% (χ20.91): −7.7% (χ20.85), corresponding in 7 to initial staging and in 4 post-radiotherapy biochemical recurrence. Every infradiaphragmatic uptake (n: 24) showed accumulative pattern, with percentage increase of +9.1% (χ20.97), all of them depicted on early imaging. As for 12 supradiaphragmantic uptake, 8 of them showed clearance pattern with percentage decrease: −13.0% (χ20.95). Accumulative pattern showed in 4 of them with percentage increase +13.0% (χ2 0.96), thus being assessed as invasive/malignant. Every bone uptake (n: 18) showed accumulative pattern, with percentage increase: +17.1% (χ20.95), all of them depicted on 1 hour imaging. CONCLUSIONS: As for prostate assessment is concerned, dual point at 0 min/1 hour proved to be the best procedure. As for supradiaphragmatic lymph-nodes detection, dual point with 1/2 hours performed best. As for infradiaphragmatic and bone involvement, as well as for inconclusive findings, the 2 hour imaging increased our diagnostic confidence

OBJETIVOS: Determinar la prevalencia de diabetes diagnosticada (DD) y su control en presos de Cataluña. MATERIAL Y MÉTODOS: Estudio transversal realizado en cuatro prisiones catalanas de hombres, entre abril y mayo de 2016. Se calculó la prevalencia de DD mediante un muestreo intencional, recogiéndose: a) datos de diabetes: tipo, valor de hemoglobina glucosilada (HbA1c) y tratamiento; b) comorbilidades; c) variables epidemiológicas y penitenciarias; d) conocimiento sobre hiperglucemia/hipoglucemia; y e) participación en actividades educativas. Se consideró un control óptimo si la HbA1c era menor del 7,5%; y de alto riesgo si la HbA1c era mayor del 9%. Para estudiar la asociación entre variables cualitativas, se utilizó la prueba de chi cuadrado o Χ2. Para determinar las variables asociadas al control óptimo, se realizó un análisis multivariante mediante una regresión logística. RESULTADOS: Se estudiaron 4.307 pacientes, con una edad media de 50,2 años. Se detectaron 93 DD (2,16%), 23,7% diabetes tipo 1 (DT1) y 76,3% tipo 2 (DT2). El 22,6% mantenía tratamiento con insulina, el 51,6% con antidiabéticos orales (ADO) y el 25,8% con ambos. Los pacientes con DT1 eran más jóvenes, delgados, diagnosticados más jóvenes, más consumidores de drogas y decían saber actuar ante hiperglucemias/hipoglucemias. El control óptimo era más frecuente en la DT2, pero solo se asoció al tratamiento con ADO. DISCUSIÓN: La prevalencia de DD es muy inferior a la extrapenitenciaria y posiblemente está subestimada. El control óptimo es bajo, y el de riesgo, muy alto, probablemente por el tipo de población, frecuentemente drogodependiente y con pocos hábitos saludables. Se recomienda aplicar programas de diabetes o mejorar los actuales con objeto de incrementar el diagnóstico y optimizar el control de la enfermedad
OBJECTIVES: To determine the prevalence of diagnosed diabetes (DD) and its control amongst prisoners in Catalonia. MATERIALS AND METHODS: Transversal study carried out in four Catalan prisons between April and May 2016. The prevalence of DD in inmates was calculated by intentional sampling and collecting the following variables about: a) type of diabetes, value of glycosylated hemoglobin (HbA1c) and treatment; b) comorbidities; c) epidemiological and prison variables; knowledge of hyperglycaemia/hypoglycaemia, and e) participation in educational activities. Optimal control was considered to exist if Hb1A <7.5% and high risk if Hb1Ac >9%. Test χ² was used in order to study the association among qualitative variables. Multivariate analysis was carried out using logistic regression to determine variables associated with disease control. RESULTS: The study group considered 4,307 male patients, 50.2 years of average age. Ninety three cases of DD were detected (prevalence 2.16%).22.6% were treated with insulin, 51.6% with oral antidiabetics (OAD) and 25.8% with both. Type 1 users were younger, thinner, diagnosed at a younger age, heavy drug users and acknowledged to know how to act in the event of hyperglycaemia/hypoglycaemia. Optimal control was more common in type 2 diabetics, but multivariate analysis only associated it with OAD treatment. DISCUSSION: The prevalence observed in DD is much lower than that of the population outside prison and may be underestimated. Optimal control is low and risk is very high, the results may be biased by the type of population, frequently drug- dependent and with few healthy habits. It is recommended to implement diabetes programmes or improve existing ones in order to increase the diagnosis and management of the disease
