Detection of gastric atrophy by circulating pepsinogens: A comparison of three assays.
2017
Background Circulating levels of pepsinogens have been used in high gastric cancer-risk Asian and European populations to triage endoscopic evaluation for more severe pathology. There are different analytic methods with uncertain correlations. We therefore compared diagnostic performance of three commonly used pepsinogen assays to detect histologically confirmed gastric atrophy. Methods We tested plasma samples from adult patients with (n=50) and without (n=755) moderate or severe gastric corpus atrophy, as determined histologically by consensus of three expert pathologists. A single laboratory measured pepsinogens I (PgI) and II (PgII) using commercially available assays: two ELISA assays …
Clinical features, disease progression and use of healthcare resources in a large sample of 866 patients from 24 headache centers: A real-life perspe…
2021
Objective: To develop a dedicated Italian chronic migraine (CM) database (IRON project) to overcome disease misconceptions, improve clinical administration, reduce patients' burden, and rationalize economic resource allotment.Background: Proper CM management requires a comprehensive appraisal of its full clinical, social, and economic complexity.Methods: In this cross-sectional study, CM patients were screened in 24 certified headache centers with face-to-face interviews. Information on sociodemographic factors, medical history, characteristics of CM, and of prior episodic migraine (EM), and healthcare resource use was gathered using a semistructured web-based questionnaire.Results: A total…
The occupational role of dental conditions among a consecutive sample of Spanish workers
2010
Objectives: To assess the occupational impact of the mouth in terms of days of work loss in the last year and the perception of the working performance disturbance because of the oral conditions. Study design: A consecutive sample (n=269) of the Regional Government staff of the province of Granada (Spain) was recruited. Participants were asked about work loss related to health problems in the past 12 months, capturing the aetiological entities, the frequency of the work absent and the total days loss. Also subjects reported if they believed that mouth affects their occupational performance, and if they have perceived difficulties for carrying out work because of the mouth. Data on sociodemo…
Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…
2018
The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …
Non-contact breath sampling for sensor-based breath analysis
2019
Breath analysis holds great promise for real-time and non-invasive medical diagnosis. Thus, there is a considerable need for simple-in-use and portable analyzers for rapid detection of breath indicators for different diseases in their early stages. Sensor technology meets all of these demands. However, miniaturized breath analyzers require adequate breath sampling methods. In this context, we propose non-contact sampling; namely the collection of breath samples by exhalation from a distance into a miniaturized collector without bringing the mouth into direct contact with the analyzing device. To evaluate this approach different breathing maneuvers have been tested in a real-time regime on a…
Liking for fat is associated with sociodemographic, psychological, lifestyle and health characteristics
2014
Sensory liking influences dietary behaviour, but little is known about specifically associated individual profiles. The aim of the present study was to investigate the associations between liking for fat-and-salt and fat-and-sweet sensations and sociodemographic, economic, psychological, lifestyle and health characteristics in a large sample. Individual characteristics and liking scores were collected by a questionnaire among 37 181 French adults. Liking scores were constructed using a validated preference questionnaire. Multinomial logistic regression models were used to assess the associations between liking levels and individual characteristics. In both sexes, subjects belonging to low-l…
Further examination of the organizational culture scale of artifacts
2009
The construct validity of a 10-item Organizational Culture Scale Focused on Artifacts oriented to measure traditional culture was analyzed under the unidimensionality hypothesis of the scale. Confirmatory factor analysis was conducted to assess the unidimensional structure, which took into account the method effects associated with reverse-worded items. The results based on the data from a sample of 926 subjects, 79.8% male, mean age of 33.4 years (SD = 12.8), working in different types of companies suggested the proposed unidimensional factor structure, with the elimination of two items from the scale. The resulting 8-item scale was reanalyzed, this time with the data of a second split-sam…
Self-Rated Health and Associated Factors Among Men of Different Ages
1986
The connections of certain clinico-physiological indicators of health state, chronic diseases, felt symptoms, and psychic well-being with self-rated health were studied among men of different ages as a part of the more extensive research project Jyväskylä Studies on Functional Aging. Study population was selected by using systematic random sampling among men aged 31 to 35, 51 to 55 and 71 to 75 years in the city of Jyväskylä. Log-linear and logit models as well as regression and structural equation models within the framework of LISREL were used as methods of analysis. The associations between general self-rated health and the explanative variables were different in different age groups: In…
Effects of alertness management training on sleepiness among long-haul truck drivers : a randomized controlled trial
2018
Education is a frequently recommended remedy for driver sleepiness in occupational settings, although not many studies have examined its usefulness. To date, there are no previous on-road randomized controlled trials investigating the benefits of training on sleepiness among employees working in road transport. To examine the effects of an educational intervention on long-haul truck drivers' sleepiness at the wheel, amount of sleep between work shifts, and use of efficient sleepiness countermeasures (SCM) in association with night and non-night shift, a total of 53 truck drivers operating from southern Finland were allocated into an intervention and a control group using a stratified random…
In vitro production of GHB in blood and serum samples under various storage conditions
2011
Abstract The in vitro production of GHB was observed in freshly collected, untreated whole blood samples using glass BD-Vacutainers and polypropylene S-monovettes. GHB concentrations were determined daily over a period of one week and after 3, 6 and 9 weeks again. Furthermore, the GHB concentration in 40 untreated random whole blood samples stored at 4 °C for a longer period of time (10 samples 12 month, 10 samples 24 month and 20 samples 36 month) was also determined. For comparison, the in vitro production of GHB in freshly collected and prepared serum samples was observed. GHB serum concentrations were determined three times over a period of one week and once again after six weeks. Sampl…
