Desarrollo de las competencias básicas de los estudiantes de educación superior mediante la e-Evaluación orientada al aprendizaje
2013
Learning Oriented e-Assessment (e-LOA) is an ICT mediated learning process. It promotes the development of competences that are relevant to both students’ academic present and professional future. In this quasi-experimental research a pretest-posttest design with experimental and control groups is implemented. We believe that the actions of e-LOA favors further development of competences. The results show that in the experimental groups there is an improvement on the level of competence. Significant differences have been found between the pretest and posttest. In addition, there is a consistency between the competences that have improved and those considered in the literature (creativity, p…
Inequalities and the Impact of Job Insecurity on Health Indicators in the Spanish Workforce
2020
In a context of high job insecurity resulting from social deregulation policies, this research aims to study health and substance abuse inequalities in the workplace from a gender perspective. To this end, a transversal study was carried out based on microdata from the National Health Survey in Spain&mdash
Subjective Well-Being, Emotional Intelligence, and Mood of Parents: A Model of Relationships. Impact of Giftedness
2020
The well-being of parents could be either a protective or risk factor for themselves or their children. Our objective is to analyse the affective components of subjective well-being (SWB), emotional intelligence (EI), and parental mood. Parents of gifted children may be a vulnerable group because they face exceptional challenges in raising their children, sometimes with neither educational nor social support. We assess whether parents&rsquo
Internet- and mobile-based aftercare and relapse prevention in mental disorders: A systematic review and recommendations for future research
2018
Background Mental disorders are characterized by a high likelihood of recurrence. Thus, aftercare and follow-up interventions aim to maintain treatment gains and to prevent relapse. Internet- and mobile-based interventions (IMIs) may represent promising instruments in tertiary prevention. This systematic review summarizes and evaluates the research on the efficacy of IMIs as aftercare or follow-up interventions for adults with mental health issues. Methods A systematic database search (PsycInfo, MEDLINE, CENTRAL) was conducted and studies selected according to predefined eligibility criteria (RCTs, adult population, clinical symptoms/disorder, assessed with validated instruments, clinical-p…
Further evaluation of plasma sphingomyelin levels as a risk factor for coronary artery disease
2006
Abstract Background Sphingomyelin (SM) is the major phospholipid in cell membranes and in lipoproteins. In human plasma, SM is mainly found in atherogenic lipoproteins; thus, high levels of SM may promote atherogenesis. Methods We investigated in a median follow up of 6.0 years the association of SM with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) in stable and unstable patients, and its relation to other marker of atherosclerosis in 1,102 patients with angiographically documented CAD and 444 healthy controls. Results and discussion Logistic regression analysis showed that SM categorized by median was associated with an elevated risk for CAD (HR 3.2…
Endocrine Challenges in Patients with Continuous-Flow Left Ventricular Assist Devices
2021
Heart failure (HF) remains a leading cause of morbidity, hospitalization, and mortality worldwide. Advancement of mechanical circulatory support technology has led to the use of continuous-flow left ventricular assist devices (LVADs), reducing hospitalizations, and improving quality of life and outcomes in advanced HF. Recent studies have highlighted how metabolic and endocrine dysfunction may be a consequence of, or associated with, HF, and may represent a novel (still neglected) therapeutic target in the treatment of HF. On the other hand, it is not clear whether LVAD support, may impact the outcome by also improving organ perfusion as well as improving the neuro-hormonal state of the pat…
Complémentarité et équilibre de l’apport alimentaire en protéines et en lipides
2003
The nature and level of dietary protein is liable to influence cholesterol and essential fatty acid (EFA) metabolism. Dietary vegetable protein, particularly the undigested fraction, decreases intestinal cholesterol absorption, increases the faecal excretion of steroids, and enhances the catabolism of cholesterol-carrying lipoproteins by increasing the activity or number of LDL receptors. However, the hypocholesterolemic effect of protein may be due to the presence of non-protein components and hence the purity degree of the selected protein, and the concomitant addition or not of cholesterol. Dietary proteins with different amino acid composition may modulate the secretion of hormones (e.g…
Clinical and Molecular-Genetic Insights into the Role of Oxidative Stress in Diabetic Retinopathy: Antioxidant Strategies and Future Avenues
2020
Reactive oxygen species (ROS) overproduction and ROS-signaling pathways activation attack the eyes. We evaluated the oxidative stress (OS) and the effects of a daily, core nutritional supplement regimen containing antioxidants and omega 3 fatty acids (A/ω3) in type 2 diabetics (T2DM). A case-control study was carried out in 480 participants [287 T2DM patients with (+)/without (−) diabetic retinopathy (DR) and 193 healthy controls (CG)], randomly assigned to a daily pill of A/ω3. Periodic evaluation through 38 months allowed to outline patient characteristics, DR features, and classic/OS blood parameters. Statistics were performed by the SPSS 24.0 program. Diabetics displayed significantly h…
Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise
2021
This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…
Effects of Norepinephrine and Cardiotrophin-1 on Phospholipase D Activity and Incorporation of Myristic Acid Into Phosphatidylcholine in Rat Heart
2004
The present study is part of a project on phospholipase D (PLD) in cardiac hypertrophy and analyzed effects on PLD activity of two growth stimuli, norepinephrine (NE) and cardiotrophin-1 (CT-1), in incubated rat heart. Phosphatidylcholine (PC) was labeled by 3H-myristic acid. PLD produced 3H-phosphatidylethanol (3H-PEth) from 3H-PC in the presence of ethanol and maintained a basal formation of 3H-PEth. Short-term and long-term exposure to NE for 2 or 13 h, respectively, enhanced the formation of 3H-PEth, which was blocked by prazosin. Long-term pretreatment with NE or CT-1 increased the incorporation of 3H-myristic acid into PC, which was blocked by atenolol. When the 3H-PEth formation was …
