These are the main results from a multicentre, multinational study conducted by various research teams, including the Centre for Research in Environmental Epidemiology (CREAL- Centre de Recerca en Epidemiologia Ambiental) and the Municipal Institute of Medical Research (IMIM- Institut Municipal d’Investigació Mèdica- Hospital del Mar). Other teams from Germany, Canada, Holland, Italy, the United Kingdom and Sweden have participated as well, under the coordination of the CREAL–IMIM researchers. These results have been recently published in the online edition of the American Journal of Respiratory and Critical Care Medicine.
Certain previous epidemiological studies have shown a risk of asthma amongst cleaning professionals. Nevertheless, no study had been designed that was able to demonstrate this relation in the non-professional or domestic cleaning setting. A total of 3,503 people were monitored in the European Community Respiratory Health Survey (ECRHS) once the ethical committees from the 22 participating health centres (from 10 different countries) accepted the study protocol. The participants were men and women between the ages of 20 and 44 who were initially free of asthma at the time they joined the study. They regularly cleaned their homes and accepted the conditions of their participation in the study by signing the corresponding informed consent document.
The survey revealed that these participants regularly used up to fifteen different types of cleaning products with various frequencies: daily; from one to three days a week; once a week; or even less. Throughout the study, the presence of respiratory illness was assessed through diagnosis, symptoms and the use of asthma treatments.
The researchers of this study have confirmed that “despite the fact that the use of aerosol cleaners is related to a significant risk of developing asthma in adults, this finding requires future research in order to identify the actual chemical composition responsible for the sensitisation and the characteristic inflammatory reactions of the induced respiratory effects in adults”.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
