Obesity greater risk for fatty liver than moderate amounts of alcohol

Being overweight and resistant to insulin constitute a greater risk for fatty liver than was previously thought, according to a study from Linköping University in Sweden that is now being published in the journal Annals of Medicine.

It has long been known that large amounts of alcohol can cause fatty liver. More recent research has shown that obesity and insulin resistance can also cause fatty liver, which in turn is closely associated with diabetes, high blood pressure, and cardiovascular disease.

Thus far it has been seen as sufficient to drink just over half a glass of wine per day for women and one glass for men to bring about fatty liver. Many people with fatty liver have therefore been asked by their physician to abstain from alcohol. If the liver condition nevertheless did not improve, physicians have assumed that the patient ignored their advice and drank too much alcohol anyway.

The two researchers professor Fredrik Nyström and assistant professor Stergios Kechagias at Linköping University are now showing that moderate amounts of alcohol everyday do not cause fatty liver. In their study, 44 individuals participated and were randomized to either abstain entirely from alcohol or drink one glass of red wine per day for women and two glasses for men for three months. Before and after the trial the subjects provided blood samples, and the fatty content of the liver was measured with state of the art magnetic resonance imaging.

“It turned out that the amount of fat in the liver was linked with obesity and insulin resistance and was almost not at all affected by the red wine. Specifically, after three months, none of the the wine drinkers had developed fatty liver or elevated liver transaminases” explains Stergios Kechagias, who is a liver specialist at LiU.

What’s more, the harmful LDL cholesterol was 16 percent lower at the end of the study in those who drank red wine compared with total abstainers.

“There is a strong correlation between moderate intake of alcohol and decreased risk of cardiovascular disease, and our data provides a mechanism for this since LDL-cholesterol was lowered to such a large extent” says Fredrik Nyström at LiU.

Fatty liver can lead to cirrhosis of the liver and is the most common liver ailment in the Western world. Roughly every fourth Swede presently has fatty liver.

Im Focus: Space observation with radar to secure Germany's space infrastructure

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...

Im Focus: Researchers Discover New Anti-Cancer Protein

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...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

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...
