Seroprevalence of Toxoplasma gondii antibodies in wild dolphins from the Spanish Mediterranean coast.
2004
Although Toxoplasma gondii infection has been found occasionally in cetaceans, little is known of the prevalence of antibodies to T. gondii in wild dolphins. Antibodies to T. gondii were determined in serum samples from 58 dolphins stranded in the Spanish Mediterranean coast. Modified agglutination test was used to determine T. gondii antibodies, and a titer of 1:25 was considered indicative of T. gondii infection. Antibodies to T. gondii were found in 4 of 36 striped dolphins (Stenella coeruleoalba), in 2 of 4 common dolphins (Delphinus delphis), in 4 of 7 bottlenose dolphins (Tursiops truncatus), and in 1 harbour porpoise (Phocoena phocoena). Antibodies were not found in 9 Risso's dolphin…
Quality control for exposure assessment in epidemiological studies
2010
In the framework of an epidemiological study, dosemeters were used for the assessment of radio frequency electromagnetic field exposure. To check the correct dosemeter's performance in terms of consistency of recorded field values over the entire study period, a quality control strategy was developed. In this paper, the concept of quality control and its results is described. From the 20 dosemeters used, 19 were very stable and reproducible, with deviations of a maximum of +/- 1 dB compared with their initial state. One device was found to be faulty and its measurement data had to be excluded from the analysis. As a result of continuous quality control procedures, the confidence in the meas…
Spatial analysis of the relationship between mortality from cardiovascular and cerebrovascular disease and drinking water hardness
2004
Journal Article; Research Support, Non-U.S. Gov't; Reproduced with permission from Environmental Health Perspectives. Previously published scientific papers have reported a negative correlation between drinking water hardness and cardiovascular mortality. Some ecologic and case-control studies suggest the protective effect of calcium and magnesium concentration in drinking water. In this article we present an analysis of this protective relationship in 538 municipalities of Comunidad Valenciana (Spain) from 1991-1998. We used the Spanish version of the Rapid Inquiry Facility (RIF) developed under the European Environment and Health Information System (EUROHEIS) research project. The strateg…
Depressive symptoms in late life : Results from a study in three Nordic urban localities.
1995
The prevalence and correlates of depressive symptoms among 75-year-olds were examined in three Nordic urban localities: Gothenburg, Sweden (n=446), Jyvaskyla, Finland (n=382) and Glostrup, Denmark (n=541). Depressive symptomatology was assessed with the Center for Epidemiologic Studies Depression Scale (CES-D). Prevalence figures for depressiveness seemed to be somewhat higher in Jyvaskyla than in the two other localities. Women had more depressive symptoms than men in all three areas. The lowest mean score was recorded for Danish men and the highest level of symptoms in Finnish women. The associations discovered in this Nordic comparative study between demographic characteristics and depre…
Smoking cessation opportunities in severe mental illness (tobacco intensive motivational and estimate risk — TIMER—): study protocol for a randomized…
2019
There is an increased risk of premature death in people with severe mental illness (SMI). Respiratory disorders and cardiovascular disease are leading causes of increased mortality rates in these patients, and tobacco consumption remains the most preventable risk factor involved. Developing new tools to motivate patients towards cessation of smoking is a high priority. Information on the motivational value of giving the lung age and prevention opportunities is unknown in this high-risk population. In the context of community care, screening and early detection of lung damage could potentially be used, together with mobile technology, in order to produce a prevention message, which may provi…
“Default” versus “pre-atopic” IgG responses to foodborne and airborne pathogenesis-related group 10 protein molecules in birch-sensitized and nonatop…
2014
Background The route and dose of exposure are believed to be relevant factors in the sensitization process. Pathogenesis-related group 10 protein (PR-10) molecules are a family of allergenic proteins shared by many pollens (eg, birch and alder) and foods (eg, apple, peach, and soy). Children are exposed to both pollen-derived (inhaled) and food-derived (ingested) PR-10 molecules. Objective We sought to investigate the role of route and dose of exposure in the evolution of IgG and IgE responses to recombinant PR-10 molecules. Methods The German Multicentre Allergy Study examined a birth cohort born in 1990. Blood samples were collected at the ages of 1, 2, 3, 5, 6, 7, 10, and 13 years. Parti…

Chronic hepatitis B in Italy: New features of an old disease - Approaching the universal prevalence of hepatitis B e antigen-negative cases and the e…
2008
We evaluated 1336 hepatitis B surface antigen-positive subjects consecutively observed in 79 Italian hospitals over a 6-month period. The proportion of hepatitis B e antigen-negative cases was 86.4%, that of patients coinfected with hepatitis D virus was 9.7%, and the rate of patients coinfected with hepatitis C virus was 16.8%. Multiple logistic regression analysis showed that age >49 years, alcohol abuse, and anti-hepatitis D virus and anti-hepatitis C virus positivity were independent predictors of progression to liver cirrhosis. © 2007 by the Infectious Diseases Society of America.

Morphological and Postural Changes in the Foot during Pregnancy and Puerperium: A Longitudinal Study
2021
The aim of this study is to observe the morphological and postural changes to the foot that take place during pregnancy and the puerperium. Method: In this descriptive, observational, longitudinal study, we analysed 23 pregnant women, with particular attention to morphological and postural aspects of the foot, at three time points during and after pregnancy: in weeks 9–13 of gestation, weeks 32–35 of gestation and weeks 4–6 after delivery. The parameters considered were changes in foot length, the Foot Posture Index (FPI) and the Hernández Corvo Index, which were analysed using a pedigraph and taking into account the Body Mass Index (BMI). The same procedure was conducted in each review. Re…
Nutrient Intake and Depression Symptoms in Spanish Children: The ANIVA Study
2016
The aim of this study was to examine the relationship between nutritional intake and depressive symptoms in Valencian schoolchildren. The ANIVA (Antropometria y Nutricion Infantil de Valencia) study is a descriptive cross-sectional study. During academic year 2013–2014, 710 schoolchildren aged 6–9 years were selected from eleven primary schools in Valencia (Spain). Children’s dietary intake was measured on three-day food records, completed by parents/guardians; children completed the 20-item Center for Epidemiologic Studies Depression Scale for Children (CES-DC) Questionnaire to measure depressive symptoms. Weight, height, and body mass index (BMI), and z-scores were evaluated in all subjec…
