Screen time among Spanish university students with disabilities: a self-organizing maps analysis
2019
Abstract Background:Screen time can play a significant role in the health and quality of life of people with disabilities.However, there is a lack of studies on this issue among people with disabilities, and even fewer in the universitysetting. Thus, the aim of our study was to explore the relationships between screen time, disability grade, bodymass index (BMI), physical activity and sociodemographic variables (gender and socioeconomic status) in universitystudents with different disabilities. Methods:A cross-sectional study was conducted on a sample of 1091 students with disabilities from 55 Spanishuniversities. Instruments used for data gathering were the Adolescent Sedentary Activity Qu…
Night Work and Mortality: Prospective Study Among Finnish Employees Over the Time Span 1984 to 2008
2012
There is considerable evidence showing that night work is associated with increased morbidity, but only a few studies have focused on its relation to mortality. This study investigates the relationship between the type of working-time arrangement (weekly night work/daytime work) and total and cause-specific mortality among men and women. The data consist of a representative working conditions survey of Finnish employees conducted in 1984 (2286 men/2216 women), which has been combined with register-based follow-up data from Statistics Finland covering the years 1985-2008. In the 1984 survey, the employees were asked if they worked during the night (23:00-06:00 h) and if so, how often. In thi…
Knowledge of and attitudes to influenza vaccination in healthy primary healthcare workers in Spain, 2011-2012
2013
Annual influenza vaccination is recommended for healthcare workers, but many do not follow the recommendation. The objective of this study was to investigate the factors associated with seasonal influenza vaccination in the 2011– 2012 season. We carried out an anonymous web survey of Spanish primary healthcare workers in 2012. Information on vaccination, and knowledge and attitudes about the influenza vaccine was collected. Workers with medical conditions that contraindicated vaccination and those with high risk conditions were excluded. Multivariate analysis was performed using unconditional logistic regression. We included 1,749 workers. The overall vaccination coverage was 50.7% and was …
Visualizing knowledge and attitude factors related to influenza vaccination of physicians
2014
To characterize groups of primary healthcare physicians according to sociodemographic data, years of professional experience and knowledge of and attitudes to influenza, and to evaluate differences between groups with respect to influenza vaccination in the 2011-2012 season.We carried out an anonymous web survey of Spanish primary healthcare physicians in 2012. Information on vaccination, and knowledge of and attitudes to influenza was collected. Multiple correspondence analysis and cluster analysis were used to define groups of physicians.We included 835 physicians and identified three types. Type B were physicians with low professional experience of influenza. Types A and C were physician…
Stress-induced pro- and anti-inflammatory cytokine concentrations in panic disorder patients
2018
Abstract Background An attenuated responsivity of the hypothalamus–hypophysis-adrenal (HPA) axis upon challenge and an increased risk for cardiac events are relatively consistent findings in panic disorder (PD) patients. Due to cytokine-HPA interactions, an altered HPA-axis responsivity may be accompanied by altered cytokine concentrations. Immunological reactions under stress might be considered the missing link for explaining an increased cardiac risk. This study analyzed stress-induced cytokine levels in PD patients. Methods A total of n = 32 PD patients and n = 32 healthy control individuals performed the Trier Social Test (TSST). Blood sample collection accompanied the TSST for the col…

Attrition and Use of Proxy Respondents and Auxiliary Information in the Sicilian Neuroepidemiologic Study
1994
Two-phase prevalence surveys with screening (phase 1) and examination (phase 2) are useful for some chronic diseases. Attrition, which may bias estimates, occurs in either phase because some eligible subjects die before contact, some refuse to cooperate, some are incapacitated, and some are unreachable. This investigation relates to a survey of neurologic diseases conducted in three municipalities of Sicily (prevalence date, November 1, 1987) and considers the attrition experienced and the use of proxy respondents in phase 1 and auxiliary information in phase 2 to offset, in part, this attrition. Regarding case finding, the salvage effort was more productive for decreased and incapacitated …
Detection of lung cancer in exhaled breath with an electronic nose using support vector machine analysis
2017
Lung cancer is one of the most common malignancies and has a low 5-year survival rate. There are no cheap, simple and widely available screening methods for the early diagnostics of lung cancer. The aim of this study was to determine whether analysis of exhaled breath with an artificial olfactory sensor using support vector analysis can differentiate patients with lung cancer from healthy individuals and patients with other lung diseases, regardless of the stage of lung cancer and the most common comorbidities. Patients with histologically or cytologically verified lung cancer, healthy volunteers and patients with other lung diseases (e.g. chronic obstructive pulmonary disease (COPD), asthm…
How does the quality of surveys for nutrient intake adequacy assessment compare across Europe? A scoring system to rate the quality of data in such s…
2009
Research was conducted within the EURopean micronutrient RECommendations Aligned (EURRECA) Network of Excellence, to find the best practice in assessing nutrient intakes. Objectives include: to search for and use data on individual nutrient intake adequacy (NIA) assessment collected in twenty-eight European countries and the four European Free Trade Association countries; to design and test innovative tools for data quality analysis. The information was obtained using the method described by Blanquer et al. in the present issue. The best-practice criteria were devised to select the most appropriate survey in each country. Then a survey quality scoring system was developed in consultation wi…
Methodological considerations to determine the effect of exercise on brain-derived neurotrophic factor levels.
2015
Objectives: Physical exercise up-regulates brain-derived neurotrophic factor (BDNF) in the brain and blood. However, there is yet no consensus about the adequate blood processing conditions to standardize its assessment. We aimed to find a reliable blood sample processing method to determine changes in BDNF due to exercise. Design and methods: Twelve healthy university students performed an incremental cycling test to exhaustion. At baseline, immediately after exercise, and 30 and 60 min of recovery, venous blood was drawn and processed under different conditions, i.e. whole blood, serum coagulated for 10 min and 24 h, total plasma, and platelet-free plasma. BDNF concentration was measured …
