Discapacidad y estrés percibido en pacientes de atención primaria con depresión mayor
2020
Background: Major depressive disorder (MDD) is highly prevalent in the Spanish primary care (PC) setting and the leading cause of disability in Spain. The aim of this study was to evaluate several key psychometric properties of the Sheehan Disability Scale (SDS) in patients with or without MDD and varying degrees of symptom severity using the Patient Health Questionnaire-9 (PHQ-9). Method: A total of 1,704 PC patients participating in the PsicAP clinical trial completed the SDS and PHQ-9. We evaluated the factor structure, measurement invariance across gender, internal consistency, and the discriminative and predictive validity. Results: Confirmatory factor analyses revealed a unifactorial …
Consistency between GRUAN sondes, LBLRTM and IASI
2017
Abstract. Radiosonde soundings from the GCOS Reference Upper-Air Network (GRUAN) data record are shown to be consistent with Infrared Atmospheric Sounding Instrument (IASI)-measured radiances via LBLRTM (Line-By-Line Radiative Transfer Model) in the part of the spectrum that is mostly affected by water vapour absorption in the upper troposphere (from 700 hPa up). This result is key for climate data records, since GRUAN, IASI and LBLRTM constitute reference measurements or a reference radiative transfer model in each of their fields. This is specially the case for night-time radiosonde measurements. Although the sample size is small (16 cases), daytime GRUAN radiosonde measurements seem to h…
Azaciclofanos modificados para el estudio de moléculas de interés biológico
2018
Como miembro investigador en grupo de Química Supramolecular de la Universitat de València el autor de la presente tesis ha orientado su trabajo a desarrollar y cumplir los objetivos marcados en el mismo, que consisten en el diseño, síntesis y estudio de compuestos bioactivos con acción antioxidante, antitumoral y/o antiparasitaria. Así pues, se diseñaron y sintetizaron siete nuevos ligandos poliamínicos para la obtención de nuevos complejos antioxidantes así como para evaluar su interacción con secuencias de ácidos nucleicos. Este proceso requirió, en algunos casos, del desarrollo y la puesta a punto de nuevas rutas sintéticas. Dado que las poliaminas poseen por definición varios grupos su…
Cold recycling of reclaimed asphalt pavements
2018
Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/ or maintain the existing road network while preserving and sustaining limited natural resources. The re-usage of existing pavement materials to reconstruct/ rehabilitate our future pavements is the solution that is now more and more selected by the different road administrations around the world. However, upon closer inspection, one can find many areas and details, not negligible issues, that are simply extensions of HMA technology (i.e. mix design proc…
An Easy Assessment of Frailty at Baseline Independently Predicts Prognosis in Very Elderly Patients With Acute Coronary Syndromes.
2017
Background: Information about the impact of frailty in patients with acute coronary syndromes (ACS) is scarce. No study has assessed the prognostic impact of frailty as measured by the FRAIL scale in very elderly patients with ACS. Methods: The prospective multicenter LONGEVO-SCA registry included unselected patients with ACS aged 80 years or older. A comprehensive geriatric assessment was performed during hospitalization, including frailty assessment by the FRAIL scale. The primary endpoint was mortality at 6 months. Results: A total of 532 patients were included. Mean age was 84.3 years, 61.7% male. Most patients had positive troponin levels (84%) and high GRACE risk score values (mean 16…
Effect of Foot Orthoses and Shoes in Parkinson's Disease Patients : A PRISMA Systematic Review
2021
[Abstract] Reduced plantar foot sensation, postural instability, and gait difficulties are characteristic of Parkinson´s disease patients. A systematic review was carried out to determine the effect of the different types of insoles and shoes in these patients. Several databases were used to search for relevant articles reporting Parkinson´s disease patients undergoing treatment with any type of insole and footwear. All titles and abstracts were reviewed independently by two reviewers and the available data were extracted. The study eligibility criteria were any type of experimental study that included Parkinson’s disease patients treated with any type of insole or footwear. Eight studies w…
Protective role of mindfulness, self-compassion and psychological flexibility on the burnout subtypes among psychology and nursing undergraduate stud…
2021
Abstract To explore the relationship between mindfulness, self-compassion and psychological flexibility, and the burnout subtypes in university students of the Psychology and Nursing degrees, and to analyse possible risk factors for developing burnout among socio-demographic and studies-related characteristics. Design Cross-sectional study conducted on a sample of 644 undergraduate students of Nursing and Psychology from two Spanish universities. Methods The study was conducted between December 2015 and May 2016. Bivariate Pearson's correlations were computed to analyse the association between mindfulness facets, self-compassion and psychological flexibility, and levels of burnout. Multivar…
Antioxidative component of docosahexaenoic acid in the brain in diabetes
2020
The mechanisms underlying diabetic encephalopathy are only partially understood. This chapter tries to address the mechanisms of diabetes-induced cell and tissue damage in the brain, and discusses whether docosahexaenoic acid (DHA) could attenuate the degenerative changes observed in the diabetic brain. DHA is involved in brain and retina physiological functions, aging, and neurological and behavioral illnesses. There are a large number of bioactive metabolites of DHA, namely, maresins, protectins, resolvins, electrophilic oxo-derivatives, epoxides, neuroprostanes, neuroketals, and different DHA conjugates. Among them stands out Neuroprotectin D1 (NPD1), the first identified stereoselective…
