Risk of blood clots in veins hereditary

30.05.2011
In a nationwide study, researchers at the Centre for Primary Health Care Research in Malmö, Sweden, have mapped the significance of hereditary factors in venous thromboembolism.

Venous thromboembolism (VTE) is the third most common type of cardiovascular disease after coronary heart disease and stroke. Researchers at the Centre for Primary Health Care Research in Malmö have mapped the significance of hereditary factors for venous thromboembolism in the entire Swedish population by studying the risk of VTE in children of parents with VTE compared with the children of parents who have not had VTE.

“Previously, hereditary factors for venous thromboembolism have only been studied on a small scale. We based our study on the entire Swedish population”, says Bengt Zöller, researcher at the Centre for Primary Health Care Research, Malmö. Using the national multi-generation register and hospital discharge register, the researchers examined the risk of being affected if one or both parents have had venous thromboembolism. During the period 1987 to 2007, a total of 45 362 people suffered from venous thromboembolism, of whom 4 865 had hereditary VTE and thus a higher risk of being affected.

The study shows that hereditary factors are of most significance at a younger age – between 10 and 50 – and occur in both men and women. The highest relative risk was seen in the 10–19 age group. After the age of 50, other factors appear to play a greater role than hereditariness. Blood clots in the very young, under the age of 10, are rare, but strangely enough, hereditary factors do not appear to be the most significant in this age group. The highest risk occurs if both parents have had venous thromboembolism.

“The findings are an important guide to the importance of hereditary factors for VTE. In conclusion, a parental history of venous thromboembolism is an important risk factor that should be included in the clinical medical history and examination”, says Bengt Zöller.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
