Origen y razones del consumo de psicofármacos y analgésicos en la población general.

Se investiga en este trabajo el origen y razones del consumo de psicofármacos y analgésicos en una comunidad de Cantabria. El 2,6± 1% de los varones y el 10,7 ±2% de las mujeres consumen psicofármacos, siendo para ambos sexos los porcentajes de consumo de analgésicos significativamente más altos (varones = 6,5 ± 2 %; mujeres = 16,4 ± 3 %). Distintos factores como el sexo femenino o la presencia de enfermedad física o psíquica incrementan de forma significativa el consumo de dichos fármacos. Se observó, sin embargo, que la presencia de enfermedad psíquica (medida mediante el sistema PSECA TEGO-ID) se asociaba a tratamiento psicofarmacológico sólo en un reducido número de casos. Es más, en aquellos cuadros depresivos o psicóticos que recibían tratamiento farmacológico, éste solía pertenecer al grupo de las benzodiacepinas. Se evidenció además en nuestro estudio una clara interacción entre factores psicosociales y los modos o formas de consumo definidos como "auto-consumo" o "consumo bajo control médico ". Dicha interacción demuestra la existencia de perfiles sociodemográficos específicos para cada uno de dichos modos de consumo

LFI 30 and 44 GHz receivers Back-End Modules

The 30 and 44 GHz Back End Modules (BEM) for the Planck Low Frequency Instrument are broadband receivers (20% relative bandwidth) working at room temperature. The signals coming from the Front End Module are amplified, band pass filtered and finally converted to DC by a detector diode. Each receiver has two identical branches following the differential scheme of the Planck radiometers. The BEM design is based on MMIC Low Noise Amplifiers using GaAs P-HEMT devices, microstrip filters and Schottky diode detectors. Their manufacturing development has included elegant breadboard prototypes and finally qualification and flight model units. Electrical, mechanical and environmental tests were carried out for the characterization and verification of the manufactured BEMs. A description of the 30 and 44 GHz Back End Modules of Planck-LFI radiometers is given, with details of the tests done to determine their electrical and environmental performances. The electrical performances of the 30 and 44 GHz Back End Modules: frequency response, effective bandwidth, equivalent noise temperature, 1/f noise and linearity are presented

Alectinib after failure to crizotinib in patients with ALK-positive non-small cell lung cancer : results from the Spanish early access program

Altres ajuts: Roche Farma, S.A.This retrospective observational study analyzed the clinical characteristics, treatment patterns and outcomes of 120 patients with advanced ALK-positive nonsmall-cell lung cancer (ALK+ NSCLC) according to data collected between November 2019 and October 2020 in 38 Spanish hospitals. Patients had progressed after 1-5 prior treatment lines (which included crizotinib in any prior line) and received subsequent therapy with alectinib in a local expanded access program. Median age was 58.7 years, 50% of patients were female, 64.1% had ECOG PS of 0-1, 85% presented stage IV, 95% had adenocarcinoma histology and 20.8% had brain metastases. After a median 9.6 months of alectinib treatment, objective response rate (ORR) was 54.5%, disease control rate (DCR) was 80%, median progression-free survival (PFS) was 9.4 months and median overall survival (OS) was 24.1 months. Patients with brain metastases achieved an intracranial DCR of 71.4%. Adverse events (AEs) were reported in 35.8% of patients (14.2% of AEs were grade ≥3). Over 40% of patients received some treatment after alectinib, most frequently lorlatinib (65.2%) and brigatinib (32.6%). This study provides information on real-world treatment patterns and confirms the tolerability and prolonged PFS and OS observed with alectinib in clinical trials, in unselected pretreated patients with advanced ALK+ NSCLC

La infección del tracto urinario como causa principal de ingreso en pacientes cistectomizados

Introducción y objetivos La cistectomía radical con derivación urinaria asociada a linfadenectomía pélvica ampliada continúa siendo el tratamiento de elección en el cáncer vesical musculoinvasivo. Un 64% de los pacientes presentan complicaciones postoperatorias, siendo la infección urinaria responsable en un 20-40% de los casos. El objetivo del presente proyecto es valorar la tasa de infección urinaria como causa de reingreso tras cistectomía, e identificar factores protectores y predisponentes de infección urinaria en nuestro medio. Por último, conocer los resultados obtenidos al aplicar el protocolo de profilaxis antibiótica tras la retirada de los catéteres ureterales. Material y métodos Estudio descriptivo retrospectivo de pacientes cistectomizados en el Servicio de Urología del Hospital Clínico Universitario desde enero de 2012 hasta diciembre de 2018. Desde octubre de 2017, de forma estandarizada, a todo paciente se le aplica un protocolo de prevención de infección del tracto urinario (ITU) tras la retirada de catéteres. Resultados La ITU es responsable del 54, 7% de los reingresos, siendo un 55, 1% de estos por causa de una ITU tras la retirada de los catéteres ureterales. El 9, 5% de los pacientes con profilaxis presenta ITU tras la retirada, frente a un 10, 6% en el grupo de pacientes sin profilaxis. El paciente que reingresa por ITU tras la retirada tiene un tiempo de catéteres medio de 24, 3 ± 7, 2 días, frente a los 24, 5 ± 7, 4 días en el grupo sin ITU (p = 0, 847). Conclusiones El tipo de derivación urinaria empleada no guarda relación con la tasa de infección urinaria. El modelo de regresión no identifica la profilaxis antibiótica, ni tampoco el tiempo de catéteres, como factores independientes de ITU tras la retirada de los catéteres. Introduction and objectives: Radical cystectomy with urinary diversion associated with extended pelvic lymphadenectomy continues to be the treatment of choice in muscle invasive bladder cancer. Sixty-four percent of patients submitted to this procedure present postoperative complications, with urinary infection being responsible in 20-40% of cases. The aim of this project is to assess the rate of urinary infection as a cause of re-admission after cystectomy, and to identify protective and predisposing factors for urinary infection in our environment. Finally, we will evaluate the outcomes after the establishment of a prophylactic antibiotic protocol after removal of ureteral catheters. Material and methods: Retrospective descriptive study of cystectomized patients in the Urology Service of the Hospital Clínico Universitario of Zaragoza, from January 2012 to December 2018. A urinary tract infection (UTI) prevention protocol after catheter removal is established for all patients since October 2017. Results: UTI is responsible for 54.7% of readmissions, with 55.1% of these being due to UTI after removal of ureteral catheters. Of the patients who received with prophylaxis, 9.5% presented UTIs after withdrawal, compared to 10.6% in the group of patients without prophylaxis. The patient who is re-admitted for UTI after withdrawal has a mean catheter time of 24.3 ± 7.2 days, compared to 24.5 ± 7.4 days for patients in the group without UTI (P =.847). Conclusions: The type of urinary diversion performed is not related to the rate of urinary infection. The regression model does not identify antibiotic prophylaxis, nor catheter time, as independent factors of UTI after catheter removal

The combinatorics of plane curve singularities. How Newton polygons blossom into lotuses

This survey may be seen as an introduction to the use of toric and tropical geometry in the analysis of plane curve singularities, which are germs $(C,o)$ of complex analytic curves contained in a smooth complex analytic surface $S$. The embedded topological type of such a pair $(S, C)$ is usually defined to be that of the oriented link obtained by intersecting $C$ with a sufficiently small oriented Euclidean sphere centered at the point $o$, defined once a system of local coordinates $(x,y)$ was chosen on the germ $(S,o)$. If one works more generally over an arbitrary algebraically closed field of characteristic zero, one speaks instead of the combinatorial type of $(S, C)$. One may define it by looking either at the Newton-Puiseux series associated to $C$ relative to a generic local coordinate system $(x,y)$, or at the set of infinitely near points which have to be blown up in order to get the minimal embedded resolution of the germ $(C,o)$ or, thirdly, at the preimage of this germ by the resolution. Each point of view leads to a different encoding of the combinatorial type by a decorated tree: an Eggers-Wall tree, an Enriques diagram, or a weighted dual graph. The three trees contain the same information, which in the complex setting is equivalent to the knowledge of the embedded topological type. There are known algorithms for transforming one tree into another. In this paper we explain how a special type of two-dimensional simplicial complex called a lotus allows to think geometrically about the relations between the three types of trees. Namely, all of them embed in a natural lotus, their numerical decorations appearing as invariants of it. This lotus is constructed from the finite set of Newton polygons created during any process of resolution of $(C,o)$ by successive toric modifications.Comment: 104 pages, 58 figures. Compared to the previous version, section 2 is new. The historical information, contained before in subsection 6.2, is distributed now throughout the paper in the subsections called "Historical comments''. More details are also added at various places of the paper. To appear in the Handbook of Geometry and Topology of Singularities I, Springer, 202

Epidemiología y características del ictus isquémico en el adulto joven en Aragón

Introducción Alrededor de 15 millones de personas sufren un ictus cada año, de los que un 10-15% ocurre en menores de 50 años (ictus en el adulto joven). La prevalencia de los distintos factores de riesgo vascular y las estrategias sanitarias para el manejo del ictus varían a nivel mundial, siendo interesante conocer la epidemiología y las características específicas de cada región. El objetivo de este estudio fue determinar la prevalencia de los diferentes factores de riesgo vascular, la etiología y las características de los ictus isquémicos en el adulto joven en la comunidad autónoma de Aragón. Métodos Estudio multicéntrico, de corte transversal, realizado por los Servicios de Neurología de todos los hospitales del Servicio Aragonés de Salud (SALUD). Se identificó a todos los pacientes entre 18 y 50 años que ingresaron en cualquiera de estos hospitales con el diagnóstico de ictus isquémico o AIT entre enero del 2005 y diciembre del 2015. Se recogieron variables demográficas, factores de riesgo vascular y tipo de ictus isquémico entre otras. Resultados En el periodo de estudio, 786 pacientes entre 18 y 50 años ingresaron con el diagnóstico de ictus isquémico o AIT en algún hospital del SALUD, con una tasa anual promedio de 12, 3 por 100.000 habitantes. La mediana de su edad fue de 45 años (RIQ: 40-48 años). El factor de riesgo vascular más prevalente fue el tabaquismo, 404 (51, 4%). La mayoría fue de causa indeterminada (36, 2%), seguida por «otras causas» (26, 5%). La mediana de puntuación en la escala NIHSS fue de 3, 5 (RIQ: 2, 07, 0). En total, 211 (26, 8%) de los ingresos fueron por AIT. De los pacientes que ingresaron con el diagnóstico de ictus isquémico, 59 (10, 3%) se fibrinolizaron. Conclusiones El ictus isquémico en el adulto joven no es infrecuente en Aragón y en un importante número de casos es de etiología indeterminada, por lo que es necesario implementar medidas que nos permitan mejorar su estudio, disminuir su incidencia y prevenir su recurrencia. Introduction: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. Methods: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. Results: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. Conclusions: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence

Assessment of a New ROS1 Immunohistochemistry Clone (SP384) for the Identification of ROS1 Rearrangements in Patients with Non–Small Cell Lung Carcinoma: the ROSING Study

Introduction: The ROS1 gene rearrangement has become an important biomarker in NSCLC. The College of American Pathologists/International Association for the Study of Lung Cancer/Association for Molecular Pathology testing guidelines support the use of ROS1 immunohistochemistry (IHC) as a screening test, followed by confirmation with fluorescence in situ hybridization (FISH) or a molecular test in all positive results. We have evaluated a novel anti-ROS1 IHC antibody (SP384) in a large multicenter series to obtain real-world data. Methods: A total of 43 ROS1 FISH-positive and 193 ROS1 FISH-negative NSCLC samples were studied. All specimens were screened by using two antibodies (clone D4D6 from Cell Signaling Technology and clone SP384 from Ventana Medical Systems), and the different interpretation criteria were compared with break-apart FISH (Vysis). FISH-positive samples were also analyzed with next-generation sequencing (Oncomine Dx Target Test Panel, Thermo Fisher Scientific). Results: An H-score of 150 or higher or the presence of at least 70% of tumor cells with an intensity of staining of 2+ or higher by the SP384 clone was the optimal cutoff value (both with 93% sensitivity and 100% specificity). The D4D6 clone showed similar results, with an H-score of at least 100 (91% sensitivity and 100% specificity). ROS1 expression in normal lung was more frequent with use of the SP384 clone (p < 0.0001). The ezrin gene (EZR)-ROS1 variant was associated with membranous staining and an isolated green signal FISH pattern (p = 0.001 and p = 0.017, respectively). Conclusions: The new SP384 ROS1 IHC clone showed excellent sensitivity without compromising specificity, so it is another excellent analytical option for the proposed testing algorithm
