Epidemiology of foodborne Norovirus outbreaks in Catalonia, Spain
2008
Abstract Background Noroviruses are one of the principal biological agents associated with the consumption of contaminated food. The objective of this study was to analyse the size and epidemiological characteristics of foodborne outbreaks of gastroenteritis in Catalonia, a region in the northeast of Spain. Methods In all reported outbreaks of gastroenteritis associated with food consumption, faecal samples of persons affected were analysed for bacteria and viruses and selectively for parasites. Study variables included the setting, the number of people exposed, age, sex, clinical signs and hospital admissions. The study was carried out from October 2004 to October 2005. Results Of the 181 …
Alveolar echinococcosis: characteristics of a possible emergence and new perspectives in epidemiosurveillance
2001
International audience; The aim of this review is to discuss the situation of alveolar echinococcosis in France, in the light of the current knowledge on its transmission patterns in the world, especially Europe. An important risk of higher contamination of the rural environment may be suspected from newly reported cases of infected foxes or voles in several countries where the disease was not found before. Furthermore, the increase of prevalence rate in foxes in Bade-Würtemberg (Germany) and Franche-Comté (France), traditionally endemic, is also in support of this new trend. Urban foxes and the spreading of infected foxes to cities may also be the cause of the extension to urban and suburb…
Is Homelessness a Risk Factor for Eye Disease?
2005
<i>Background:</i> There is general agreement on the presence of a correlation between poverty and impaired health. However, only scarce data are available on whether this also applies to the incidence of eye disease. The present study was carried out to evaluate the prevalence of ocular disease in homeless people in Germany. <i>Methods:</i> 107 homeless people (97 male, 10 female; mean age 49 years, range 18–81 years) treated in specialised social service institutions were investigated prospectively according to a standardised ophthalmological screening protocol. This comprised visual acuity, assessment of pupillary light reaction, intra-ocular pressure, slit lamp e…
Evaluation of oral anticoagulation therapy: Rationale and design of the thrombEVAL study programme
2013
Since decades, oral anticoagulation (OAC) with vitamin K antagonists (VKA) is an established therapy for both prevention and treatment of thromboembolism in daily clinical routine. Increasing life expectancy, demographic changes, and novel oral anticoagulants have led to an increasing complexity of medical therapy. However, data on quality and management of VKA therapy with phenprocoumon in current medical care are limited. Our aim is to investigate the quality of OAC with VKA in current health care and to evaluate the potential for improvements.The investigator-initiated thrombEVAL study programme comprises two cohorts of patients treated with vitamin K antagonists for oral anticoagulation…
Assessing alcohol consumption through wastewater-based epidemiology: Spain as a case study
2020
Background In this study, an alternative and complementary method to those approaches currently used to estimate alcohol consumption by the population is described. This method, known as wastewater-based epidemiology (WBE), allows back-calculating the alcohol consumption rate in a given population from the concentrations of a selected biomarker measured in wastewater. Methods Composite (24-h) wastewater samples were collected at the inlet of 17 wastewater treatment plants located in 13 Spanish cities for seven consecutive days in 2018. The sampled area covered 12.8% of the Spanish population. Wastewater samples were analyzed to determine the concentration of ethyl sulfate, the biomarker use…

Air pollution and stroke. A new modifiable risk factor is in the air
2019
Abstract Evidence from epidemiological studies has demonstrated that outdoor air pollution is now a well-known major problem of public health, mainly in low and middle income countries. Contrasting with myocardial infarction , there are few data on the association of air pollution and stroke. Methods We propose a narrative literature review of the effects and the underlying biological mechanisms of short- and long-term exposure to air pollutants on stroke risk and mortality, using the following key-words: stroke, cerebrovascular events, ischemic and haemorrhage stroke, transient ischaemic attack , mortality, air pollution and air pollutants. Results Twenty-one papers were selected. Air poll…
Association of Birth Weight with Central and Peripheral Corneal Thickness in Adulthood-Results from the Population-Based German Gutenberg Health Stud…
2021
Low birth weight (BW) is associated with altered ocular geometry such as a steeper corneal shape in adulthood. However, it is unclear whether low birth weight affects corneal thickness development in the center or periphery in adulthood which may contribute to ocular disease. The purpose of this study was to investigate corneal thickness in former low birth weight individuals in adulthood. Methods: The German Gutenberg Health Study is a prospective, population-based study in which every participant (age range 40–80 years) was measured with Scheimpflug imaging (Pentacam HR, Oculus Optikgeräte GmbH, Wetzlar, Germany). BW was collected by self-reports. The relationship between birth weight and…
The ISTH bleeding assessment tool as predictor of bleeding events in inherited platelet disorders: Communication from the ISTH SSC Subcommittee on Pl…
2021
Background: The ISTH Bleeding Assessment Tool (ISTH-BAT) has been validated for clinical screening of suspected von Willebrand disease (VWD) and for bleeding prediction. Recently it has been validated for subjects with inherited platelet disorders (IPD) (BAT-VAL study). Objectives: To determine whether the ISTH-BAT bleeding score (BS) predicts subsequent bleeding events requiring treatment in IPD patients. Methods: Patients with IPD, type 1 VWD (VWD-1) and age- and sex-matched healthy controls enrolled in the BAT-VAL study were prospectively followed-up for 2 years and bleeding episodes requiring treatment were recorded. Results: Of the 1098 subjects initially enrolled, 955 were followed-up…
Appropriateness of admission and hospital stay in obstetric wards: an Italian cross-sectional study comparing Sicilian settings
2015
Appropriateness is one of the main topics of health policy and should be estimable in order to analyze the efficacy of hospital services. The Review and Use of the Hospital Protocol (in Italian: Protocollo di Revisione dell’Uso dell’ Ospedale-PRUO) allowed us to evaluate the appropriateness of hospitalizations, starting from daily available clinical records in a selected hospital. Methods The cross-sectional study applied the PRUOmethod on a sample of medical records (N=575; years: 2008–2010) related to ordinary admissions to obstetric wards of Lipari and Pantelleria Hospital (both Minor Islands of Sicily: MI) and to the Teaching Hospital of the University of Palermo (P) in order to evaluat…
