Health benefits of bluefin tuna consumption: (Thunnus thynnus) as a case study.

Consumers are increasingly interested in food products with high nutritional value and health benefits. For instance, fish consumption is linked with diverse positive health benefits and the prevention of certain widespread disorders, such as obesity, metabolic syndrome, or cardiovascular diseases. These benefits have been attributed to its excellent nutritional value (large amounts of high-quality fatty acids, proteins, vitamins, and minerals) and bioactive compounds, while being relatively low-caloric. Atlantic bluefin tuna (Thunnus tynnus) is one of the most consumed species worldwide, motivated by its good nutritional and organoleptic characteristics. Recently, some organizations have proposed limitations on its consumption due to the presence of contaminants, mainly heavy metals such as mercury. However, several studies have reported that most specimens hold lower levels of contaminants than the established limits and that their richness in selenium effectively limits the contaminants' bioaccessibility in the human body. Considering this situation, this study aims to provide baseline data about the nutritional composition and the latest evidence regarding the beneficial effects of Atlantic bluefin tuna consumption. A review of the risk-benefit ratio was also conducted to evaluate the safety of its consumption, considering the current suggested limitations to this species' consumption.

[Review of a series of cases of Creutzfeldt-Jakob disease in a tertiary care hospital]. / Revisión de una serie de casos de enfermedad de Creutzfeldt-Jakob en un hospital de tercer nivel.

INTRODUCTION: We analysed a series of patients with sporadic Creutzfeldt-Jakob disease in our setting. AIM: The aim of this study is to describe the characteristics of our sample using the new diagnostic tools based on the most recently published criteria. MATERIAL AND METHODS: A descriptive, retrospective study was conducted using a digitalised hospital register. We identified 20 cases of the sporadic type, in the period 2012-2022: eight with a pathological diagnosis and 12 with high probability. The variables sex, age at onset, time of evolution, clinical phenotype, magnetic resonance imaging (MRI) findings, 14.3.3 protein, electroencephalogram (EEG), real-time quaking-induced prion protein conversion (RT-QuIC), autopsy, pathological phenotype and genetic diagnosis were recorded. RESULTS: Of those affected, 50% were men and 50%, women, with an age at onset of 67 years (30-83) and a mean survival time of eight months (1-11 months). Cognitive impairment was the most frequent onset symptom, followed by gait ataxia. All MRI scans with long time-lapse sequences (FLAIR and DWI) were pathological, and the pattern of diffuse cortical and basal ganglia involvement was the most frequent. Altogether, 55% of the sample had an EEG with characteristic triphasic complexes. Sixty-five per cent were positive for 14.3.3 protein in cerebrospinal fluid. Four RT QuIC studies were carried out (in 2020) and all were positive. In 40% of them a confirmatory autopsy was performed, with the MM/MV1 pattern being the most frequent. CONCLUSIONS: MRI with DWI sequences is a particularly sensitive test for the diagnosis of the disease, although its sensitivity decreases in the early stages. The high specificity and sensitivity of RT-QuIC, together with a characteristic clinical diagnosis and radiological pattern, are proposed as an alternative to the pathological definitive diagnosis.

Describir las características de nuestra muestra haciendo uso de las nuevas herramientas diagnósticas según los últimos criterios publicados. Material y métodos. Realizamos un estudio descriptivo y retrospectivo mediante registro hospitalario digitalizado. Identificamos 20 casos del tipo esporádico, en el período 2012-2022, ocho con diagnóstico anatomopatológico y 12 con alta probabilidad. Se registraron las variables sexo, edad de inicio, tiempo de evolución, fenotipo clínico, hallazgos en la resonancia magnética (RM), proteína 14.3.3, electroencefalograma (EEG), conversión de proteína priónica inducida por agitación en tiempo real (RT-QuIC), autopsia, fenotipo anatomopatológico y diagnóstico genético. Resultados. Registramos un 50% de hombres y un 50% de mujeres afectos, con una edad de inicio de 67 años (30-83) y un tiempo de supervivencia medio de ocho meses (1-11 meses). El deterioro cognitivo fue el síntoma de inicio más frecuente, seguido de la ataxia de la marcha. Todas las RM con secuencias de tiempo de repetición largo (FLAIR y DWI) fueron patológicas, y el patrón de afectación cortical difusa y de los ganglios basales fue el más frecuente. El 55% de la muestra tuvo un EEG con complejos trifásicos característicos. El 65% mostró positiva la proteína 14.3.3 en el líquido cefalorraquídeo. Se realizaron cuatro estudios de RT-QuIC (en 2020) y todos fueron positivos. En un 40% se realizó una autopsia confirmatoria, con el patrón MM/MV1 como el más frecuente. Conclusiones. La RM con secuencias de DWI constituye una prueba especialmente sensible para el diagnóstico de la enfermedad, aunque su sensibilidad disminuye en estadios precoces. La alta especificidad y la alta sensibilidad de la RT-QuIC, junto con un diagnóstico clínico y patrón radiológico característico, se plantean como alternativa al diagnóstico de certeza anatomopatológico.

Biological properties and potential of compounds extracted from red seaweeds.

Macroalgae have been recently used for different applications in the food, cosmetic and pharmaceutical industry since they do not compete for land and freshwater against other resources. Moreover, they have been highlighted as a potential source of bioactive compounds. Red algae (Rhodophyta) are the largest group of seaweeds, including around 6000 different species, thus it can be hypothesized that they are a potential source of bioactive compounds. Sulfated polysaccharides, mainly agar and carrageenans, are the most relevant and exploited compounds of red algae. Other potential molecules are essential fatty acids, phycobiliproteins, vitamins, minerals, and other secondary metabolites. All these compounds have been demonstrated to exert several biological activities, among which antioxidant, anti-inflammatory, antitumor, and antimicrobial properties can be highlighted. Nevertheless, these properties need to be further tested on in vivo experiments and go in-depth in the study of the mechanism of action of the specific molecules and the understanding of the structure-activity relation. At last, the extraction technologies are essential for the correct isolation of the molecules, in a cost-effective way, to facilitate the scale-up of the processes and their further application by the industry. This manuscript is aimed at describing the fundamental composition of red algae and their most studied biological properties to pave the way to the utilization of this underused resource.

Valorization of kiwi agricultural waste and industry by-products by recovering bioactive compounds and applications as food additives: A circular economy model.

Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops (agricultural wastes) and from the industrialization of the product (food industry waste). In the case of Actinidia cultivation, agricultural waste groups together leaves, flowers, stems and roots while food industry by-products are represented by discarded fruits, skin and seeds. All these matrices are now underexploited and so, they can be revalued as a natural source of ingredients to be applied in food, cosmetic or pharmaceutical industries. Kiwifruit composition (phenolic compounds, volatile compounds, vitamins, minerals, dietary fiber, etc.) is an outstanding basis, especially for its high content in vitamin C and phenolic compounds. These compounds possess antioxidant, anti-inflammatory or antimicrobial activities, among other beneficial properties for health, but stand out for their digestive enhancement and prebiotic role. Although the biological properties of kiwi fruit have been analyzed, few studies show the high content of compounds with biological functions present in these by-products. Therefore, agricultural and food industry wastes derived from processing kiwi are regarded as useful matrices for the development of innovative applications in the food (pectins, softeners, milk coagulants, and colorants), cosmetic (ecological pigments) and pharmaceutical industry (fortified, functional, nutraceutical, or prebiotic foods). This strategy will provide economic and environmental benefits, turning this industry into a sustainable and environmentally friendly production system, promoting a circular and sustainable economy.

[Diagnosis and management in pediatric patients with ovarian masses]. / Diagnóstico y manejo de masas ováricas en pacientes pediátricas.

OBJECTIVE: Review of the diagnosis and management of ovarian masses in children, through the identification of preoperative risk factors of malignancy, the evaluation of surgical management and its results. METHODS: Retrospective study in pediatric patients under 18 years old, managed surgically by ovarian masses. Analyzed data were symptoms, imagining, tumor markers, treatment, outcomes and pathology. The primary endpoint was ovarian malignancy. RESULTS: We identified 54 patients with ovarian masses between 2014 and 2017, of which 49 were benign and 5 malignant; The malignant ovarian masses were significantly larger than the benign, with an average of 19.4 cm vs 6.49 cm (p = 0.0001); had greater solid component in the imaging and positive tumor markers (p = 0.001) and were treated with oophorectomy plus tumor staging surgery. Forty-three patients with benign tumors underwent ovarian preservation surgery. The postoperative follow-up of all the patients was on average 3.4 months (1-25 months) and 20.3% presented pelvic pain associated with alterations of the menstrual cycle in their postoperative control. There are no reports of recurrence or contralateral ovarian tumor. CONCLUSIONS: Large masses with solid components and positive tumor markers were significant predictors of malignancy. Minimally invasive ovarian preserving surgery should be considered as the first treatment option in masses with low risk of malignancy. On the other hand, oophorectomy plus tumor staging surgery should be considered for ovarian tumors with a high risk of malignancy.

OBJETIVO: Revisión del diagnóstico y manejo de las masas ováricas en población infantil, mediante la identificación de factores de riesgo preoperatorios de malignidad, la evaluación del manejo quirúrgico y sus resultados. METODOS: Estudio retrospectivo en pacientes pediátricas menores de 18 años, intervenidas quirúrgicamente por masas ováricas. Se analizaron datos como síntomas, imágenes diagnósticas, marcadores tumorales, tratamiento, resultados y patología. La variable principal fue malignidad ovárica. RESULTADOS: Se identificaron 54 pacientes con masas ováricas entre el año 2014 a 2017, de las cuales 49 fueron benignas y 5 malignas. Las masas ováricas malignas fueron significativamente más grandes que las benignas, con media de 19,4 cm vs 6,49 cm (p = 0,0001); tuvieron mayor componente sólido en los hallazgos imagenológicos y marcadores tumorales positivos (p = 0,001) y fueron tratadas con ooforectomía más cirugía de estadificación tumoral. A 43 pacientes con tumores benignos se les realizó cirugía preservadora de ovario. El seguimiento postoperatorio de todas las pacientes fue en promedio de 3,4 meses (1-25 meses) y el 20,3% presentaron dolor pélvico asociado a alteraciones del ciclo menstrual en su control postoperatorio. No hay reportes de recidiva ni tumor de ovario contralateral. CONCLUSIONES: Masas grandes, con componentes sólidos y marcadores tumorales positivos fueron predictores significativos de malignidad. La cirugía preservadora de ovario por vía mínimamente invasiva debe ser considerada como primera opción de tratamiento en masas con bajo riesgo de malignidad; Por otra parte, la ooforectomía más cirugía de estadificación tumoral, debe ser considerada para los tumores ováricos con alto riesgo de malignidad.

Pérdida celular endotelial corneal asociada a facoemulsificación y experiencia del oftalmólogo: análisis prospectivo de datos secundarios individuales / Corneal endothelial cell loss associated to phacoemulsification and ophthalmologist experience: prospective analysis of individual secondary data

Resumen Introducción La facoéresis es el procedimiento en que se extrae quirúrgicamente el cristalino para tratar las cataratas. La pérdida endotelial corneal es una complicación reconocida. Si bien se han descrito diversos factores asociados a este daño, la experiencia del cirujano ha sido poco explorada. Objetivos Evaluar la asociación entre la experiencia del cirujano y otras variables asociadas a la pérdida celular endotelial en el contexto de la facoéresis. Métodos Se analizaron registros clínicos de 198 cirugías de cataratas, evaluando el efecto de la experiencia del cirujano y otras variables asociadas: energía disipada acumulada, tipo de viscoelástico empleado, uso de azul tripán, cantidad de fluídica, tiempo de ultrasonido, energía de facoemulsificación combinada y recuento celular endotelial pre y postoperatorio. Resultados No se observaron diferencias en el conteo postoperatorio de células endoteliales. Los oftalmólogos con más de cinco años de experiencia presentaron menor uso de azul tripán pero mayor cantidad de energía disipada acumulada en cada procedimiento, mientras que los oftalmólogos con menor experiencia utilizaron mayor cantidad de fluídica. Conclusiones Aunque hubo diferencias en el manejo de algunos factores influyentes sobre la pérdida endotelial cornal según la experiencia de los oftalmólogos, no se hallaron diferencias en relación a dicha pérdida como resultado final.

Abstract Introduction Phacoeresis is the procedure through which the lens is surgically removed to treat cataracts. A corneal endothelial loss is a recognized sequel. Although several factors associated with this harm have been described, the surgeon's prior experience has been scarcely evaluated. Objectives To assess the association between the surgeon's experience and other variables associated with a corneal endothelial cell loss in the context of phacoeresis. Methods Clinical records of 198 patients undergoing cataract operations were prospectively reviewed. The experience of the surgeon and other variables were recorded, including cumulative dissipated energy, viscoelastic type, the use of trypan blue, amount of fluidics, ultrasound time, combined phacoemulsification energy, and pre- and postoperative corneal endothelial cell counts. Results No differences were observed in the postoperative corneal endothelial cell count between surgeons with more or less than five years of experience. Nevertheless, ophthalmologists with more than five years' experience used less trypan blue, but more cumulative dissipated energy in each procedure, while less experienced ophthalmologists used less fluidics. Conclusions Although there were differences in the surgical management regarding the surgeons' experience in factors known to influence corneal endothelial cell loss, no differences in endothelial cell loss were observed as an outcome.

[Hematuria and sharp renal failure as debut of secondary bladder amiloidosis. Presentation of a new case and revision of the literature]. / Hematuria y fracaso renal agudo como debut de amiloidosis vesical secundaria. Presentación de un nuevo caso y revisión de la literatura.

The primary bladder amiloidosis is an uncommon pathology, not existing in the world more than 150 published cases, being even more exceptional the secondary bladder amiloidosis being described around 25 cases. The secondary bladder amiloidosis associates in most from the patients to arthritis reumatoide of long evolution. The diagnoses clinical it is difficult, being necessary the differential diagnosis with the bladder tumour. The pathological study and inmunohistochemics, confirm the diagnosis. We present the case of a patient that I debut with frank hematuria, hemodynamic uncertainty and renal inadequacy that it required combined treatment, doctor and surgical for the resolution of their square.

[Myofibroblastic tumor of bladder]. / Tumor miofibroblástico de vejiga.

The myofibroblastic tumor, is a mesenchymal benign tumor of exceptional character, being its localization but habitual it is the lung; while its appearance in the bladder, is exceptional, not existing but of 100 published cases, of this tumor type in the bladder. This tumor type that clinic and radiologics, behave as a wicked tumor. The pathological diagnosis is complex, due to its similarity with the sarcomas, being necessary to appeal to the inmunohistochemics for a I diagnose of certainty. The treatment by means of wide resection is usually enough not existing any case of metastasis at the present time at distance, neither of malignization. We present a new case of this neoplasm, carrying out a wide bibliographical revision.

[Proceedings in the implantation of a laparoscopic radical prostatectomy program]. / Implantación de un programa de prostatectomia radical laparoscópica.

OBJECTIVE: To describe our proceedings in the implatation of our laparoscopic radical prostatectomy program (LRP). METHODS: Our working agenda and step-oriented implementation of our LRP program are shown. RESULTS: Four main steps were scheduled to acomplish this goal. These were: Preparatory phase, programed open conversion, development and analysis. Overlapping of each of these phase occured although their major content run on a time-basis. After basic skills acquisition and updating of our equipment we moved into the fixed-time open conversion we allowed us to progresively improve our performance without putting our patients into risks. Operative time of this phase exceeds that of our open cases in 63 minutes and no major complications took place. A rapid decrease in the operative time was noted after the first 15 cases (197' vs 264'). CONCLUSION: Implantation of a program of LRP can be done safely with a pre-planned program tailored to the needs and characteristics of each group and institution.

Implantación de un programa de prostatectomía radical laparoscópica / Proceedings in the implantation of a laparoscopic radical prostatectomy program

Objetivo: Exponer la implantación de nuestro programa de prostatectomía radical laparoscópica (PRL). Material y métodos: Se presenta la metodología y el plan de trabajo seguido en nuestro Centro. Resultados. La implantación del programa de PRL se hace en diferentes de fases coincidentes de manera parcial cronológicamente: fase de preparatoria, fase de reconversión programada, fase de desarrollo y fase de análisis. La primera es un periodo de aprendizaje de la técnica laparoscópica y de adquisición de equipamiento. La fase de reconversión realizada sobre nueve pacientes supone el comienzo de la técnica laparoscópica con una limitación en el tiempo para evitar alargamiento del tiempo quirúrgico y morbilidad. En nuestra experiencia, el incremento medio de tiempo quirúrgico ha sido de 63 minutos respecto a la prostatectomía radical abierta y no hemos tenido complicaciones mayores en este periodo. El tiempo quirúrgico medio disminuyó rápidamente tras los primeros 15 pacientes (197’ vs 264’). Conclusiones: La implantación de un programa de PRL es factible sin que conlleve riesgos añadidos a los pacientes haciéndolo mediante una planificación ordenada previamente que se debe ajustar a las particularidades de cada grupo e institución (AU)

[Treatment with sildenafil of cold glands syndrome after inflatable penile prosthesis]. / Tratamiento con sildenafilo del síndrome de glande frío tras implante de prótesis hidráulica de pene.

OBJECTIVE: To evaluate the effect of sildenafil on the response of glans penis during sexual intercourse in patients with penile prosthesis who show cold glans syndrome symptoms. MATERIAL AND METHODS: Fourteen patients who had undergone three-piece inflatable penile prosthesis implantation were evaluated. In spite of the normal functioning of the device all of them complained of a degree of dissatisfaction during SI due to a lack of engorgement in the glans penis. The patients were advised to have a dose of 100 mg VO sildenafil about 45 minutes before activating the PP and starting SI. All of them followed this scheme at least three times. They ticked questions 7, 8, 13 and 14 of the International Index of Erectile Function (IIEF) questionnaire with/without having had sildenafil. RESULTS: Twelve out of thirteen patients (85.7%) indicated a more pleasant SI on sildenafil. It was related to an increase in penile glans engorgement and sensitivity. The scores obtained in the IIEF questions showed a significant increase on taking sildenafil. The partners also talked of a more comfortable SI that they related to a less painful penetration. Sildenafil-related morbidity was not found. CONCLUSIONS: Sildenafil could be used to improve functional results of the penile prosthesis in those patients with CGS and seems to increase satisfaction during SI.

Tratamiento con sildenafilo del síndrome de glande frio tras implante de prótesis hidráulica de pene / Treatment with sildenafil of cold glands síndrome after inflatable penile prosthesis

OBJETIVO: Evaluar el efecto de sildenafilo en la respuesta peneana glandular durante la relación sexual (RS) en pacientes con prótesis de pene que muestran síntomas sugerentes de síndrome de glande frío (SGF). MATERIAL Y MÉTODO: Evaluamos catorce pacientes a quienes se había implantado una prótesis de pene (PP) hidráulica de tres piezas. A pesar de un funcionamiento normal del dispositivo, todos los pacientes se quejaban de diversos grados de insatisfacción durante la RS debido a falta de incremento de volumen en glande. Se recomendó a los pacientes la ingestión de una dosis de 100 mg de sildenafilo unos 45 minutos antes de activar la PP e iniciar la RS. Todos ellos siguieron este esquema al menos en tres ocasiones. Respondieron las cuestiones 7, 8, 13 y 14 del Índice Internacional de Función Eréctil (IIEF) con/sin dosis previa de sildenafilo. RESULTADOS: Doce de los catorce pacientes (85,7%) indicaron una RS más placentera tras ingerir sildenafilo. Este hecho fue relacionado especialmente con un incremento en la sensibilidad y volumen del glande. Las puntuaciones obtenidas en las cuestiones del IIEF mostraron un incremento significativo al tomar sildenafilo. Las parejas también referían una RS más confortable que relacionaron con una PV menos dolorosa. No se objetivó morbilidad relacionable con sildenafilo. CONCLUSIONES: Sildenafilo puede ser utilizado para mejorar los resultados funcionales de las PP en pacientes con síndrome de glande frío y parece incrementar la satisfacción durante la RS

OBJECTIVE: To evaluate the effect of sildenafil on the response of glans penis during sexual intercourse in patients with penile prosthesis who show cold glans syndrome symptoms. MATERIAL AND METHODS: Fourteen patients who had undergone three-piece inflatable penile prosthesis implantation were evaluated. In spite of the normal functioning of the device all of them complained of a degreeof dissatisfaction during SI due to a lack of engorgement in the glans penis. The patients were advised to have adose of 100 mg VO sildenafil about 45 minutes before activating the PP and starting SI. All of them followed this scheme at least three times. They ticked questions 7, 8, 13 and 14 of the International Index of Erectile Function (IIEF) questionnaire with/without having had sildenafil. RESULTS: Twelve out of thirteen patients (85,7%) indicated a more pleasant SI on sildenafil. It was related toan increase in penile glans engorgement and sensitivity. The scores obtained in the IIEF questions showed a significant increase on taking sildenafil. The partners also talked of a more comfortable SI that they related to aless painful penetration. Sildenafil-related morbidity was not found. CONCLUSIONS: Sildenafil could be used to improve functional results of the penile prosthesis in those patients with CGS and seems to increase satisfaction during SI

[Neurostimulation and neuromodulation in urinary incontinence]. / Neuroestimulación y neuromodulación en la incontinencia urinaria.

Electric stimulation in Urology has undergone considerable development since the 1970s. The implantation methods for urinary system stimulation are used for bladder emptying in neurogenic bladders (Neurostimulation) or the modulation of the electrical transmission of the voiding cycle caused by chronic detrusor-sphincter dysfunction (Neuromodulation). Both techniques have in common the direct stimulation of the sacral roots, responsible for the urinary reflex arc. The first of them works via external stimulation over an implanted antenna, and the second via permanent stimulation through an implanted pacemaker. We review in this article the indications, technique and results of both therapies, specially focused on the Spanish experience.
