Brominated flame retardants and organochlorines in the European environment using great tit eggs as a biomonitoring tool
2009
Large-scale studies are essential to assess the emission patterns and spatial distribution of organohalogenated pollutants (OHPs) in the environment. Bird eggs have several advantages compared to other environmental media which have previously been used to map the distribution of OHPs. In this study, large-scale geographical variation in the occurrence of OHPs, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs), was investigated throughout Europe using eggs of a terrestrial residential passerine species, the great tit (Parus major). Great tit eggs from 22 sampling sites, involving urban, rural and remote areas, in 14 Europea…
Quantifying Excess Deaths Related to Heatwaves under Climate Change Scenarios: A multicountry time series modelling study
2018
Background: Heatwaves are a critical public health problem. There will be an increase in the frequency and severity of heatwaves under changing climate. However, evidence about the impacts of climate change on heatwave-related mortality at a global scale is limited. Methods and findings: We collected historical daily time series of mean temperature and mortality for all causes or nonexternal causes, in periods ranging from January 1, 1984, to December 31, 2015, in 412 communities within 20 countries/regions. We estimated heatwave–mortality associations through a two-stage time series design. Current and future daily mean temperature series were projected under four scenarios of greenhouse g…
Relación entre exposición a corto plazo a dióxido de azufre atmosférico y lesiones obstructivas en el síndrome coronario agudo
2013
Resumen Fundamentos y objetivo Los contaminantes del aire urbano estan constituidos por una mezcla heterogenea de sustancias presentes en estado gaseoso y aerosoles. El objetivo del presente estudio fue comparar los efectos causados por la exposicion a contaminantes en fase gas y particulas atmosfericas en aire ambiente en pacientes que ingresan por un sindrome coronario agudo (SCA), en relacion con la presencia o no de lesiones obstructivas significativas (LOS) en arterias coronarias epicardicas. Pacientes y metodo Analizamos de forma prospectiva a un total de 2.110 pacientes con el diagnostico de SCA. Se determinaron las concentraciones medias de contaminantes en fase gas y particulas atm…
Dydrogesterone use during pregnancy: Overview of birth defects reported since 1977
2009
Between 1977 and 2005, 28 cases of potential links between maternal dydrogesterone use during pregnancy and congenital birth defects were reported. The types of defects were very diverse, with no evidence of a pattern of abnormalities. The data do not provide evidence for congenital malformations associated with dydrogesterone use.
Raynaud-Phänomen bei einer beruflichen Vibrationsbelastung
2013
Anamnese und klinischer Befund: Eine 34-jahrige Steinmetzin wurde mit der Fragestellung eines vibrationsbedingten vasospastischen Syndroms (VVS) begutachtet. Ihre Hande waren langjahrig gegenuber den hochfrequenten Schwingungen verschiedener Werkzeuge exponiert gewesen. Die Patientin berichtete uber Weisfingeranfalle an den Langfingern, die bei Kalte aufgetreten waren. Der korperliche Befund war zu diesem Zeitpunkt regelrecht. Untersuchungen: Der Kaltwasserprovokationstest zeigte an den Langfingern der rechten Hand eine leicht verzogerte Wiedererwarmung; die Kapillarmikroskopie der Finger war regelrecht. Diagnose und Verlauf: Das leichtgradige Raynaud-Phanomen wurde als Berufskrankheit der …

Familial Replicating Arachnoidal Cysts: Case Series and Review of Literature
2015
Background: Arachnoid cysts are intra-arachnoid fluid collections covered by a thin membrane that may develop throughout the cerebrospinal axis. Although the precise causative mechanism is unknown, arachnoid cyst (AC) are now generally accepted to be developmental anomalies of arachnoid. These lesions have commonly been described in the literature; however the presence of familial arachnoid cysts is quite rare. Most genetically related AC have been documented in patients with a known genetic syndrome. The current case report describes a family with four members affected by an arachnoid cyst in the same region. Methods: In addition to reviewing the current case, a literature search was condu…
The Occurrence and Dietary Exposure Assessment of Mycotoxins, Biogenic Amines, and Heavy Metals in Mould-Ripened Blue Cheeses
2020
The occurrence and dietary exposure assessment of 16 mycotoxins, 6 biogenic amines (BAs), and 13 metallic elements in blue-veined cheeses (n = 46) is reported. Co-occurrence of mycophenolic acid (&le
Influence of the Urban Exposome on Birth Weight
2019
Background: The exposome is defined as the totality of environmental exposures from conception onwards. It calls for providing a holistic view of environmental exposures and their effects on human health by evaluating multiple environmental exposures simultaneously during critical periods of life. Objective: We evaluated the association of the urban exposome with birth weight. Methods: We estimated exposure to the urban exposome, including the built environment, air pollution, road traffic noise, meteorology, natural space, and road traffic (corresponding to 24 environmental indicators and 60 exposures) for nearly 32,000 pregnant women from six European birth cohorts. To evaluate associatio…
Quantitative determination of trichothecenes in breadsticks by gas chromatography-triple quadrupole tandem mass spectrometry.
2014
Breadsticks are pencil-sized sticks of dry bread widely consumed as a pre-meal appetiser. They are basically wheat-based snacks, which makes them a good matrix to evaluate mycotoxin contamination, since wheat is very susceptible to fungal attack. In this sense, the fast, selective and sensitive gas chromatography-triple quadrupole tandem mass spectrometry (GCQqQ- MS/MS) method proposed here allows simultaneous determination of deoxynivalenol (DON), 3-acetyldeoxynivalenol, fusarenon-X, diacetoxyscirpenol, nivalenol, neosolaniol, HT-2 and T-2 toxin in breadsticks after QuEChERS extraction and clean-up. The performance of the method was assessed with respect to European Commission Regulations …
