Urinary levels of enniatin B and its phase I metabolites: First human pilot biomonitoring study
2018
Abstract Enniatins (Enns) are mycotoxins produced by Fusarium spp. and are widely distributed contaminants of cereals and derivate products. Among the different identified enniatins, Enn B is the most relevant analogue in cereals in Europe. Therefore, the aim of this study was to investigate for the first time the occurrence of Enn B and Enn B phase I metabolites in 300 human urine samples throughout an ultrahigh-performance liquid chromatography-high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) methodology. Three different sample preparation procedures were evaluated and salting-out liquid-liquid extraction showed satisfactory validation results. Enn B was quantified in 83.7% of sa…
Barriers to physical activity in university students with disabilities: Differences by sociodemographic variables
2019
Abstract Background Despite the positive effects of regular physical activity (PA), university students with disabilities are less active than their able-bodied peers, which could be due to the wide range of barriers to PA that these individuals face across all social ecological levels. Objective To identify the barriers to PA experienced by university students with disabilities at the different social ecological levels and to examine the differences in these barriers by sociodemographic variables. Methods The reduced Spanish version of the Barriers to Physical Activity Questionnaire for People with Mobility Impairments was administered to a sample of 1219 Spanish university students with d…
Clinical efficacy of semiconductor laser application as an adjunct to conventional scaling and root planing.
2005
Background and Objectives: The aim of the in vitro study was to examine the clinical efficacy of semiconductor laser periodontal pocket irradiation as an adjunct to conventional scaling and root planing. Materials and Methods: Twenty-two healthy patients with a need of periodontal treatment (15 women, 7 men, mean age 45.0� 10.8 years) with at least four teeth in all quadrants, were included. All of them underwent a conventional periodontal treatment including scaling and root planing. Using a split mouth design, two randomly chosen quadrants (one upper and the corresponding lower one) were subsequently treated with an 809 nm GaAlAs laser operated at a power output of 1.0 Watt using a 0.6 mm…
Participation rates by educational levels have diverged during 25 years in Finnish health examination surveys
2018
Background Declining participation rates in health examination surveys may impair the representativeness of surveys and introduce bias into the comparison of results between population groups if participation rates differ between them. Changes in the characteristics of non-participants over time may also limit comparability with earlier surveys. Methods We studied the association of socio-economic position with participation, and its changes over the past 25 years. Occupational class and educational level are used as indicators of socio-economic position. Data from six cross-sectional FINRISK surveys conducted between 1987 and 2012 in Finland were linked to national administrative registers…
Acceptability, attitudes and knowledge towards Transcranial Magnetic Stimulation (TMS) among psychiatrists in France
2020
Abstract Background Non-invasive brain stimulation techniques are becoming a part of psychiatrists’ therapeutic arsenal. Proof of TMS effectiveness and its indications are becoming clearer. While international recommendations exist, and many countries have already recognized the use of these techniques, the French situation is peculiar since no recommendation has been published by the High Authority of Health. Consequently, those techniques are not reimbursed by the healthcare service, few practitioners are trained, some are criticized for using it, and practices remain very heterogeneous. It is therefore important to investigate what slows down the development of these techniques. The obje…
Making sense of what you sense: Disentangling interoceptive awareness, sensibility and accuracy.
2016
Garfinkel and Critchley (2013) recently proposed a three level model of interoception. Only few studies, however, have empirically tested this theoretical model thus far. The present study aimed at investigating (1) the central assumptions of this model, i.e. that Accuracy, Sensibility and Awareness are distinguishable facets of interoception and that Interoceptive Accuracy is the basic level of interoception, and (2) whether cardiovascular activation (as indexed by heart rate) is differentially related to the three facets of interoception. Analyses were conducted on a total sample of N=159 healthy participants (118 female [74.2%]; mean age=23.9years, SD=3.3, range=19-45) who performed eith…
Perceived collective burnout: a multilevel explanation of burnout
2011
Building up on the socially induced model of burnout and the job demands-resources model, we examine how burnout can transfer without direct contagion or close contact among employees. Based on the social information processing approach and the conservation of resources theory, we propose that perceived collective burnout emerges as an organizational-level construct (employees' shared perceptions about how burned out are their colleagues) and that it predicts individual burnout over and above indicators of demands and resources. Data were gathered during the first term and again during the last term of the academic year among 555 teachers from 100 schools. The core dimensions of burnout, ex…
Employability and personal initiative as antecedents of job satisfaction.
2009
In a changing and flexible labour market it is important to clarify the role of environmental and personal variables that contribute to obtaining adequate levels of job satisfaction. The aim of the present study is to analyze the direct effects of employability and personal initiative on intrinsic, extrinsic and social job satisfaction, clarifying their cumulative and interactive effects. The study has been carried out in a sample of 1319 young Spanish workers. Hypotheses were tested by means of the moderated hierarchical regression analysis. Results show that employability and personal initiative predict in a cumulative way the intrinsic, extrinsic and social job satisfaction. Moreover, th…
Situational and Dispositional Factors that Predict Motivation: a Multilevel Study
2017
AbstractThis study aimed to test a multilevel mediation model which examined the relationship between the perceived motivational climate created by coaches at team level and motivational regulations towards sport at individual level, as mediated by individual goal orientations. 211 university athletes from 20 teams training in different types of sport completed a battery of instruments that measured the variables included in the model. The statistics significance level was .05. Results of the multilevel mediation model revealed that the task-involving climate at team level positively predicted individual task orientation (γ01 = .77, p < .001) and autonomous motivation for sport practice …
High Anger Expression is Associated with Reduced Cortisol Awakening Response and Health Complaints in Healthy Young Adults
2016
AbstractThe extant evidence suggests a robust positive association between expression (anger expression-out) and suppression (anger expression-in) of anger and compromised health. Nevertheless, the underlying psychobiological mechanisms which explain these relationships are not well understood. This study examined whether anger expression would predict general health, cortisol awakening response (CAR) and evening cortisol levels in a community sample of 156 healthy young adults of both genders. Participants were distributed into two groups according to their anger expression scores: high and low anger expression (HAE and LAE, respectively). Findings indicated that those with HAE had worse s…
