Development of Burnout Syndrome in Non-university Teachers: Influence of Demand and Resource Variables.
2021
Psychosocial risks at work are an important occupational problem since they can have an impact on workers' health, productivity, absenteeism, and company profits. Among their consequences, burnout stands out for its prevalence and associated consequences. This problem is particularly noteworthy in the case of teachers. The aim of the study was to analyze the influence of some psychosocial factors (demand and resource variables) and risks in burnout development, taking into consideration the levels of burnout according to the Spanish Burnout Inventory (SBI). This paper contributes to advancing knowledge on this issue by analyzing the influence of work characteristics and personal characteris…
Persistent traffic offenders. Alcohol consumption and personality as predictors of driving disqualification
2019
espanolLa seguridad vial es un importante problema social. Muchos accidentes se deben al incumplimiento de las normas de trafico. Las infracciones graves o reiteradas se sancionan por la via administrativa o judicial y en ambos casos las sanciones pueden suponer la perdida del permiso de conducir. Este articulo explora la relevancia del alcohol y la personalidad como factores predictivos. El objetivo del estudio es determinar si el comportamiento delictivo de los infractores persistentes esta relacionado con sus caracteristicas de personalidad y patrones de consumo de alcohol. Se utilizo una muestra de 358 conductores: 232 infractores persistentes, a los que les habia sido retirado el carne…
Satisfaction and loyalty in B2B relationships in the freight forwarding industry: adding perceived value and service quality into equation
2018
This paper focuses on analysing the determinants of satisfaction (service quality, perceived value), as well as its possible influence on customer loyalty of freight forwarders to freight transport service providers (by road/maritime/air) in Spain. To this end, we propose a causal model tested using information from 205 freight forwarders collected through personal interviews. The model was estimated using the Partial Least Squares (PLS) approach. Moreover, the existence of differences in the perceptions on the analysed variables between transport modes is tested through ANOVA. Results show that service quality has an influence on customer satisfaction, both directly, as well as through per…
HEMATOLOGICAL VARIABILITY ANALYSIS AFTER ROAD MARATHON VS ULTRATRAIL. PREDICTIVE FACTORS
2020
The practice of long- and medium-distance races has exponentially increased the number of participants in recent years. They are carried out under extreme conditions that cause both biochemical and anthropometric changes in athletes and, in addition, have serious risks associated, such as dehydration, thermal disorders, or hypoglycemia. Knowledge regarding alterations at hematological level after this type of effort is limited. The objectives of this pre-post analytical descriptive observational study were: to describe and compare hematological values in amateur runners pre and post road marathon and ultratrail races, and to compare the hematological parameters between the groups in the two…
Towards data-driven medical imaging using natural language processing in patients with suspected urolithiasis.
2020
Abstract Objective The majority of radiological reports are still written as free text and lack structure. Further evaluation of free-text reports is difficult to achieve without a great deal of manual effort, and is not possible in everyday clinical practice. This study aims to automatically capture clinical information and positive hit rates from narrative radiological reports of suspected urolithiasis using natural language processing (NLP). Methods Narrative reports of low dose computed tomography (CT) of the retroperitoneum from April 2016 to July 2018 (n = 1714) were analyzed using NLP. These free-text reports were automatically structured based on RadLex concepts. Manual feedback was…
Severity of irritable bowel syndrome in patients with temporomandibular disorders: A case-control study
2019
Background To assess the risk and severity of IBS in a population of TMD patients. Material and Methods Subjects for the study group were recruited from patients attending the Dental Clinic. Health controls (HC) were recruited among patients' friends and clinic staff. All subjects filled in the RDC/TMD questionnaire and the ROME III questionnaire for the diagnosis of IBS. The IBS Severity Scoring System (IBS-SSS) was used to evaluate the severity of each case of IBS. Categorical variables were compared through the Chi square test. The risk of having abdominal pain was analysed using logistic regression. Results Twenty-two (46.8%) cases of IBS were diagnosed among TMD patients, whereas only …
Interpersonal Violence and Health in Female University Students in Spain
2016
BACKGROUND: Most studies address the health impact of violence by an intimate partner; therefore, violence exerted by someone other than a partner in university students and its health effects are less known. PURPOSE: This study aims to analyze the effect of different forms of interpersonal violence on female university students' health. DESIGN: Women 18 to 25 years of age enrolled at two schools of the University of Valencia in the academic year 2013-2014 (N = 540) were selected, with a participation rate of 82%. Students were grouped as follows: no lifetime violence, violence by an intimate partner (IPV), other personal violence (OPV), and by both (IPV and OPV). Adjusted logistical regres…
Is neural network better than logistic regression in death prediction in patients after ST-segment elevation myocardial infarction?
2021
Background: There is a need to develop patient classification methods to adjust post-discharge care, improving survival after ST-segment elevation myocardial infarction (STEMI). Aims: The study aimed to determine whether a neural network (NN) is better than logistic regression (LR) in mortality prediction in STEMI patients. Material and methods: The study included patients from the Polish Registry of Acute Coronary Syndromes (PL-ACS). Patients with the first anterior STEMI treated with the primary percutaneous coronary intervention (pPCI) of the left anterior descending (LAD) artery between 2009 and 2015 and discharged alive were included in the study. Patients were randomly divided into th…
Prevalence of Genital Human Papilloma Virus Infection and Genotypes among Young Women in Sicily, South Italy
2008
Abstract Infection with oncogenic human papilloma virus (HPV) types is a necessary cause of cervical cancer. This study assessed the prevalence of HPV infection and genotypes among 1,006 randomly selected women, ages 18 to 24 years, living in Sicily (south Italy). The overall HPV rate was 24.1% (95% confidence interval, 21.5-26.9). The most frequent types were HPV-16 (4.5%), HPV-53 (2.7%), and HPV-84 (2.6%). The prevalence of vaccine types HPV-6, HPV-11, and HPV-18 was 1.4%, 0.1%, and 1.3%, respectively. Cytologic abnormalities were uncommon (3.1%) and associated with HPV detection (P < 0.0001). The only risk factor for HPV infection was the number of sexual partners (women with 2-3 …
Fear of falling and coexisting sensory difficulties as predictors of mobility decline in older women.
2012
BACKGROUND: Mobility decline, the coexistence of several sensory difficulties and fear of falling (FOF) are all common concerns in older people; however, knowledge about the combined effect of FOF and coexisting sensory difficulties on mobility is lacking. METHODS: Data on self-reported FOF, difficulties in hearing, vision, balance, and walking 2 km were gathered with a structured questionnaire among 434 women aged 63-76 years at baseline and after a 3-year follow-up. Logistic regression models were used for analyses. RESULTS: Every third participant reported difficulties in walking 2 km at baseline. In cross-sectional analysis, the odds ratio for difficulties in walking 2 km was higher amo…
