Abstract PURPOSE: To assess the grade of satisfaction in children on intermittent catheterization with the use of LoFric and PVC conventional catheters. MATERIAL AND METHODS: A total of 40 p with experience in CIC were included in this study. An anonymous questionnaire was sent to all patients after 2-months using the LoFric catheter. Patients were divided in 3 groups (bladder augmentation, artificial sphincter, Mitrofanoff) because of major differences in CIC discomfort between these groups. RESULTS: The questionnaire was completed by 87.5% of the patients (35 p). In 86% (30 p) LoFric catheter training was easy or very easy but in 14% (5 p) it was difficult. Four patients had some difficulty during conventional catheter insertion, in 3 (75%) the difficulty disappeared with the use of LoFric catheter. Of the 51% (18 p) who reported some discomfort during the insertion of conventional catheter, 72% said it was eliminated when the LoFric catheter was used. Of 6 p with some discomfort when removing the conventional catheter, 5 (83%) said it disappeared with the new catheter. Th LoFric catheter was favored by 70% of patients because it reduced the discomfort caused by conventional catheters, bladder insertion was easier and smoother, and gel lubrication was not needed. The 17% of patients reported some difficulty dealing with this slippery catheter. CONCLUSIONS: The use of the LoFric catheter could be justified in patients who report with conventional catheters have some discomfort. It can also be recommended in patients with artificial sphincter, bladder augmentation and Mitrofanoff procedure, in whom any complication related to CIC would have serious consequences

Identidad docente y estrategias de resolución de incidentes críticos en contextos universitarios de alta diversidad sociocultural

Este estudio identifica las estrategias de los profesores cuando se enfrentan a incidentes críticos (IC) en contextos de alta diversidad sociocultural, reconociendo el peso de la identidad y de las emociones en la toma de decisiones, así como la efectividad de las mismas para promover cambios en las prácticas docentes. En el estudio de naturaleza cualitativa, fueron entrevistados 23 profesores universitarios. Los resultados indican que las emociones asociadas a un IC, generan una situación de desequilibrio que puede obstaculizar la actividad cuando son de naturaleza negativa. Al mismo tiempo, en estas situaciones es posible la revision y reconstrución de la propia identidad docente. En cuanto a las estrategias empleadas por los docentes ante los IC, éstas fueron mayoritariamente inmediatas e incidieron en aspectos muy puntuales, lo que derivó en actuaciones reactivas y poco eficaces. Pese a ello, la mayoría de los profesores no modificaron sus posiciones iniciales y fueron excepcionales las situaciones en las que el despliegue de estrategias y la reflexión posterior a un determinado IC permitió cambios estructurales que impactaron en alguna dimension de la identidad del profesor como sus emociones y prácticas

Assessing distinct patterns of cognitive aging using tissue-specific brain age prediction based on diffusion tensor imaging and brain morphometry

Multimodal imaging enables sensitive measures of the architecture and integrity of the human brain, but the high-dimensional nature of advanced brain imaging features poses inherent challenges for the analyses and interpretations. Multivariate age prediction reduces the dimensionality to one biologically informative summary measure with potential for assessing deviations from normal lifespan trajectories. A number of studies documented remarkably accurate age prediction, but the differential age trajectories and the cognitive sensitivity of distinct brain tissue classes have yet to be adequately characterized. Exploring differential brain age models driven by tissue-specific classifiers provides a hitherto unexplored opportunity to disentangle independent sources of heterogeneity in brain biology. We trained machine-learning models to estimate brain age using various combinations of FreeSurfer based morphometry and diffusion tensor imaging based indices of white matter microstructure in 612 healthy controls aged 18–87 years. To compare the tissue-specific brain ages and their cognitive sensitivity, we applied each of the 11 models in an independent and cognitively well-characterized sample (n = 265, 20–88 years). Correlations between true and estimated age and mean absolute error (MAE) in our test sample were highest for the most comprehensive brain morphometry (r = 0.83, CI:0.78–0.86, MAE = 6.76 years) and white matter microstructure (r = 0.79, CI:0.74–0.83, MAE = 7.28 years) models, confirming sensitivity and generalizability. The deviance from the chronological age were sensitive to performance on several cognitive tests for various models, including spatial Stroop and symbol coding, indicating poorer performance in individuals with an over-estimated age. Tissue-specific brain age models provide sensitive measures of brain integrity, with implications for the study of a range of brain disorders

Preclinical and randomized phase I studies of plitidepsin in adults hospitalized with COVID-19

Plitidepsin, a marine-derived cyclic-peptide, inhibits SARS-CoV-2 replication at nanomolar concentrations by targeting the host protein eukaryotic translation elongation factor 1A. Here, we show that plitidepsin distributes preferentially to lung over plasma, with similar potency against across several SARS-CoV-2 variants in preclinical studies. Simultaneously, in this randomized, parallel, open-label, proof-of-concept study (NCT04382066) conducted in 10 Spanish hospitals between May and November 2020, 46 adult hospitalized patients with confirmed SARS-CoV-2 infection received either 1.5 mg (n = 15), 2.0 mg (n = 16), or 2.5 mg (n = 15) plitidepsin once daily for 3 d. The primary objective was safety; viral load kinetics, mortality, need for increased respiratory support, and dose selection were secondary end points. One patient withdrew consent before starting procedures; 45 initiated treatment; one withdrew because of hypersensitivity. Two Grade 3 treatment-related adverse events were observed (hypersensitivity and diarrhea). Treatment-related adverse events affecting more than 5% of patients were nausea (42.2%), vomiting (15.6%), and diarrhea (6.7%). Mean viral load reductions from baseline were 1.35, 2.35, 3.25, and 3.85 log10 at days 4, 7, 15, and 31. Nonmechanical invasive ventilation was required in 8 of 44 evaluable patients (16.0%); six patients required intensive care support (13.6%), and three patients (6.7%) died (COVID-19-related). Plitidepsin has a favorable safety profile in patients with COVID-19

Internet Search and Navigation Strategies Used by Experts and Beginners.

This paper presents three pilot studies whose purpose was to analyse the way different users (experts and beginners) go about searching for specific information, both on the Internet in general and in a thematic web site in particular. It discusses the role of prior knowledge in achieving the search objectives, and highlights the differences in task completion due to the use of approaches of varying levels of strategic development

Una sentencia firme contra la mala práctica en el tratamiento de la obesidad A firm court resolution against malpractice in the treatment of obesity

Los tratamientos dietéticos incorrectos contra la obesidad pueden agravar el riesgo metabólico y cardiovascular de los pacientes, conducir a malnutriciones, facilitar en personas predispuestas el comienzo de trastornos de la conducta alimentaria, y favorecer la recuperación del peso perdido. Sin embargo, la práctica incorrecta de terapias contra el exceso de peso, a veces con promesas de resultados "milagro" sigue siendo bastante frecuente en nuestro país. La denuncia pública de un método concreto aplicado por clínicas de adelgazamiento muy populares en Madrid, realizada por la Dras. Monereo y Vázquez, resultó en una querella que el director de las citadas clínicas interpuso contra las especialistas, por supuestos delitos contra su honor. En este artículo especial se resumen los hechos, se analizan los métodos concretos empleados por el denunciante, sus posibles consecuencias perjudiciales y se resume el contenido de la sentencia de uno de los juicios ya finalizado. Las principales conclusiones de la misma son: 1) que la educación sanitaria y la defensa de la salud pública es un deber profesional; 2) que el conocimiento actual de la obesidad como enfermedad compleja y en cuyo tratamiento un enfoque incorrecto puede agravar aún más el riesgo; 3) que existen suficientes consensos españoles e internacionales que enmarcan con toda precisión los criterios de buena práctica médica en relación con la obesidad; 4) que, sin embargo continúan habiendo tratamientos que constituyen engaño o fraude de distinta índole y que obedecen a negocios más que a actividad profesional, y 5) que la situación inaudita de ser demandadas por actuaciones que sólo responden a la actuación responsable dentro de una institución y buscando el beneficio público y ajustadas a Consensos ha supuesto a nivel personal e institucional una situación grave, difícil y dolorosa. Consideramos de trascendencia e interés la difusión de esta sentencia que constituye una referencia profesional y puede ser decisiva en la lucha contra la mala práctica en el tratamiento de la obesidad.Inappropriate dietary treatments against obesity may worsen patients' metabolic and cardiovascular risk, lead to malnutrition, facilitate the appearance in predisposed individuals of eating disorders and ultimately favor the recovery of previously lost weight. Nonetheless, incorrect therapies aimed at reducing weight, sometimes accompanied by promises of miraculous results, are still rather frequent in our country. The public criticism by Drs. Monereo and Vazquez of a concrete method used by several very popular clinics in Madrid, resulted in the director of those centers suing them for libel. In this special article, we summarize the facts, analyze the methods used in those clinics and their likely negative consequences as well as sketch the content of the verdict of one of the trials, already concluded. Its main conclusions are the following: 1) Health education and the defense of public health is a professional duty; 2) The incorrect treatment of obesity can increase the risks associated with it; 3) There is a sufficient spanish and international consensus as well as Guidelines that clearly specifies the requisites of good medical practice with regard to obesity; 4) In spite of that, there are still treatments that constitute deception and fraud of different kinds and that respond more to business motivations rather than professional ones; 5) The fact of being sued as a result of activities that make part of a responsible behavior within an institution and whose purpose is the public benefit has entailed a serious, difficult and painful situation. We consider that the relevance and interest of the verdict warrants its diffusion because it constitutes a reference for professionals and may be decisive in the struggle against bad practices in obesity treatment
