Local cohomology in classical rings
The aim of this paper is to stablish the close connection between prime ideals and torsion theories in anon necessarily commutative noetherian ring. We introduce a new definition of support of a module and characterize some kinds of torsion theories in terms of prime ideals. Using the machinery introduced before, we prove a version of the Mayer-Vietoris Theorem for local cohomology and stablish a relationship between the classical dimension and the vanishing of the groups of local cohomology on a classical ring

Validation in clinical population of the Problematic Internet Entertainment Use Scale for Adults (PIEUSAd)
Addiction to technologies has been a widely debated scientific and clinically, being a condition for further study as potential psychiatric disorder. Some Spanish scales measure Internet addiction, but no one has been validated clinically. The aims were to describe a clinical sample of patients in treatment for a technology addiction, and to validate clinically the “Problematic Internet Entertainment Use Scale for Adults” (PIEUSAd). Little-scale clinical adult sample (N=31; 71 % men, and an age mean of 33.31) was selected, collecting socio-demographic and clinical data, technological usages, and the PIEUSAd and Compulsive Internet Use Scale in a survey. The setting was a public health center in Barcelona (Spain). The patients in treatment for a technological addiction as primary diagnosis were usually young males, which suffer from a genuine e-addiction (above all, internet addiction, gaming and cybersex); only the middle seems to have a dual pathology (usually another addiction). They are usually referred by other clinician and the majority don’t have previous psychiatric care. The PIEUSAd showed large variability in item scored, and high factor and construct validity, and excellent reliability (a=0.98). In conclusion, the heterogeneity in the characteristics of patients is evidenced. Moreover, the PIEUSAd has been clinical validated to do a better screen in technological addictions, where “loss of control” and “evasion” seems to be the prevalent addictive symptoms in these types of patients.
Spanish abstract: La adicción a las tecnologías ha sido debatida ampliamente tanto científica como clínicamente, siendo una condición a estudiar como potencial trastorno psiquiátrico. Algunas escalas españolas miden la adicción al internet, pero ninguna ha sido validada clínicamente. Los objetivos son describir la muestra clínica de pacientes en tratamiento por una adicción tecnológica, así como validar clínicamente la “Problematic Internet Entertainment Use Scale for Adults” (PIEUSAd). Una muestra clínica a pequeña escala (N=31; 71 % hombres, con una edad media de 33,31) fue seleccionada, se recogieron datos socio-demográficos, clínicos y de uso de tecnologías, así como la PIEUSAd y la “Compulsive Internet Use Scale” a través de una encuesta. El contexto fue un centro de salud pública de Barcelona (España). Los pacientes en tratamiento por una adicción tecnológica como primer diagnóstico eran usualmente hombres jóvenes que sufrían de una e-adicción genuina (sobre todo, adicción a internet, videojuegos o cibersexo); solo la mitad parecía sufrir una patología dual (normalmente otra adicción). Eran normalmente derivados por otros profesionales de la salud y la mayor parte no habían sido tratados psiquiá- tricamente con anterioridad. La PIEUSAd mostró gran variabilidad en sus puntuaciones, alta validez factorial y de constructo, y excelente fiabilidad (a=0,98). En conclusión, la heterogeneidad de las características de los pacientes fue evidenciada. Además, la PIEUSAd ha sido validada clínicamente para poder hacer un mejor cribado en las adicciones tecnológicas, donde la “pérdida de control” y la “evasión” parecen ser los síntomas prevalentes en estos tipos de pacientes

Diferencias psicopatológicas en mujeres con Dependencia Emocional con y sin uso de sustancias ilegales comórbido
En este artículo se presenta un análisis clínico de las diferencias psicopatológicas entre dos grupos de pacientes, mujeres, con problemas de Dependencia Emocional con y sin consumo de sustancias ilegales comórbido. Las pacientes fueron evaluadas mediante los cuestionarios TDS100, SCL-90-R, BIS-11 y una entrevista semiestructurada adaptada de la entrevista SCID-I. Los grupos se formaron en función de si existía consumo de drogas o no en el momento de la evaluación.
A través de los resultados hallados, se puede concluir que el grupo de mujeres con un consumo ocasional de drogas presenta una mayor gravedad en la escala de Acomodación medida a través del TDS-100, así como puntuaciones más altas en psicopatología comórbida (Sensibilidad Interpersonal, Ansiedad, Hostilidad, Ideación paranoide, Psicoticismo y GSI) medida por el SCL-90-R. Finalmente, el grupo con uso de drogas obtuvo puntuaciones significativamente más altas en la subescala Impulsividad Motora medida por el BIS-11.
English abstract: In this article we present a clinical analysis of the psychopathological differences between women patients with Affective Dependence problems with and without comorbid substance use. The patients were assessed trough the TDS-100, SCL-90-R, BIS-11 questionnaires and a semi-structured interview adapted from the SCID-I interview. The groups were created based on the substance use at the moment of the assessment.
The results reveal that the group of women with occasional use of drugs shows higher severity in the Accommodation scale measured trough the TDS-100 and in the comorbid psychopathology measured by the SCL-90R (Interpersonal Sensitivity, Anxiety, Hostility, Paranoid ideation, Psychoticism y GSI). Finally, the group with drug use obtained significantly higher scores in the Motor Impulsiveness subscale measured by the BIS-11
Chronic proliferative rhinitis in sheep: An update
Chronic proliferative rhinitis (CPR) is a slow and progressive upper respiratory tract disease of sheep with a poor prognosis for affected animals. It causes a proliferative inflammation of the ventral nasal turbinates with uni or bilateral affection that may totally obstruct the nasal cavity. Salmonella enterica subspecies diarizonae serovar 61:k:1, 5, (7) has been associated with the disease. This microorganism, host-adapted of tonsils and nasal cavity of sheep, has been isolated in pure culture from the nasal cavity in all reported cases of CPR. However, its etiopathogenesis, mechanism of transmission and its involvement with the disease are still unknown. The present article focuses on describing the current knowledge about this disease gathering the published information and offering some new data on the latest research carried out on chronic proliferative rhinitis in sheep

Perfil psicopatológico de pacientes con Dependencia Emocional
Diversos autores defienden la Dependencia Emocional como una categoría diagnóstica propia. El perfil psicopatológico de las personas afectadas por este trastorno ha sido expuesto a nivel teórico o basado en observaciones clínicas. Con este estudio se pretende determinar el perfil psicopatológico de una muestra de pacientes que presentaban problemas de Dependencia Emocional, desadaptativa, así como estudiar la relación entre autoestima y síntomas psicopatológicos. Se analiza el perfil sintomático a través de los resultados del Symptom CheckList-90 items-Revised (SCL-90-R) y el nivel de autoestima medido a través del Rosenberg Self-Esteem Scale (RSES) de una muestra de 33 pacientes de género femenino admitidos consecutivamente, que consultaron por problemas de dependencia emocional. Las pacientes presentaban elevada puntuación en las escalas obsesión-compulsión, sensibilidad interpersonal, depresión, ansiedad, hostilidad, ideación paranoide, psicoticismo (medidas a través del SCL-90-R) comparados con baremos normativos de población psiquiátrica española y una autoestima baja (medida a través del RSES). En la muestra la autoestima correlaciona de manera negativa con somatización, obsesión-compulsión, depresión y hostilidad. Se discuten las características y perfiles de esta muestra clínica.
English abstract: Several authors defend that Affective Dependence is a diagnostic category. The psychopathological profile of these patients has been explained from a theoretical point of view or based on clinical observations. In that study we want to determinate the pathological profile of a sample of patients with problems of affective dependence, and to study the relationship between their self-esteem and their psychopathological symptoms. We analyzed the symptomatic profile of a sample of 33 female consecutive patients consulting for affective dependence, measured trough the Symptom CheckList-90 items-Revised (SCL-90-R) and the Rosenberg Self-Esteem Scale (RSES). Patients present high obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, paranoid ideation, psychoticism (measured by the SCL- 90-R) compared with compared with normative scores of Spanish psychiatric population, and low self-esteem (measured by the RSES). In these subjects the self- esteem showed negative correlation with somatization, obsessive-compulsive, depression and hostility. These characteristics and profiles are discussed
An Effective Method for InSAR Mapping of Tropical Forest Degradation in Hilly Areas
Current satellite remote sensing methods struggle to detect and map forest degradation, which is a critical issue as it is likely a major and growing source of carbon emissions and biodiveristy loss. TanDEM-X InSAR phase height (hϕ) is a promising variable for measuring forest disturbances, as it is closely related to the mean canopy height, and thus should decrease if canopy trees are removed. However, previous research has focused on relatively flat terrains, despite the fact that much of the world’s remaining tropical forests are found in hilly areas, and this inevitably introduces artifacts in sideways imaging systems. In this paper, we find a relationship between hϕ and aboveground biomass change in four selectively logged plots in a hilly region of central Gabon. We show that minimising multilooking prior to the calculation of hϕ strengthens this relationship, and that degradation estimates across steep slopes in the surrounding region are improved by selecting data from the most appropriate pass directions on a pixel-by-pixel basis. This shows that TanDEM-X InSAR can measure the magnitude of degradation, and that topographic effects can be mitigated if data from multiple SAR viewing geometries are available
Designing and implementing a massive open online course: Lessons learnt
•In this paper, we describe the design, implementation, and evaluation of a Massive Open Online Course, or MOOC, on good practice in the application of Intellectual Property. It is aimed primarily at teachers and students, and taught in Spanish. We have used the Spanish legislation on Intellectual Property. This paper outlines the structure and content of a course developed on an ad-hoc basis, and describes its evaluation by participants in questionnaires and a final survey. The results of the initial questionnaire are framed by a) the participant''s profile, and b) by consideration of the MOOC''s implementation, given the results of the satisfaction survey. In this paper we describe the advantages of the MOOC and identify areas for improvement
Body Composition Evaluation and Clinical Markers of Cardiometabolic Risk in Patients with Phenylketonuria
Cardiovascular diseases are the main cause of mortality worldwide. Patients with phenylketonuria (PKU) may be at increased cardiovascular risk. This review provides an overview of clinical and metabolic cardiovascular risk factors, explores the connections between body composition (including fat mass and ectopic fat) and cardiovascular risk, and examines various methods for evaluating body composition. It particularly focuses on nutritional ultrasound, given its emerging availability and practical utility in clinical settings. Possible causes of increased cardiometabolic risk in PKU are also explored, including an increased intake of carbohydrates, chronic exposure to amino acids, and characteristics of microbiota. It is important to evaluate cardiovascular risk factors and body composition in patients with PKU. We suggest systematic monitoring of body composition to develop nutritional management and hydration strategies to optimize performance within the limits of nutritional therapy.info:eu-repo/semantics/publishedVersio
Clinical features of De Novo acute myeloid leukemia with concurrent DNMT3A, FLT3 and NPM1 mutations
BACKGROUND: De novo acute myeloid leukemia (AML) with concurrent DNMT3A, FLT3 and NPM1 mutations (AML(DNMT3A/FLT3/NPM1)) has been suggested to represent a unique AML subset on the basis of integrative genomic analysis, but the clinical features of such patients have not been characterized systematically. METHODS: We assessed the features of patients (n = 178) harboring mutations in DNMT3A, FLT3 and/or NPM1, including an index group of AML(DNMT3A/FLT3/NPM1) patients. RESULTS: Patients with AML(DNMT3A/FLT3/NPM1) (n = 35) were significantly younger (median, 56.0 vs. 62.0 years; p = 0.025), mostly women (65.7% vs. 46.9%; p = 0.045), and presented with a higher percentage of bone marrow blasts (p < 0.001) and normal cytogenetics (p = 0.024) in comparison to patients within other mutation groups in this study. Among patients <60 years old, those with AML(DNMT3A/FLT3/NPM1) had a shorter event-free survival (EFS) (p = 0.047). DNMT3A mutations and not FLT3 or NPM1 mutations were independently associated with overall survival (OS) (p = 0.026). Within mutation subgroups, patients with AML(DNMT3A/NPM1) had a significantly shorter OS compared to those with AML(FLT3-ITD/NPM1) (p = 0.047) suggesting that the adverse impact of DNMT3A mutations is more pronounced than that of FLT3-ITD among patients with NPM1 mutation. CONCLUSIONS: DNMT3A has a significant dominant effect on the clinical features and outcomes of de novo AML patients with concurrent DNMT3A, FLT3 and NPM1 mutations.
