(Press-News.org) New research from Karolinska Institutet in Sweden highlights the possibility of screening people with type 2 diabetes for liver damage at the same time as they undergo screening for eye disease. The study is published in Lancet Gastroenterology and Hepatology.
More than half of all people with type 2 diabetes have steatotic (or fatty) liver disease, but most do not realise it since liver disease rarely causes any symptoms in the earlier stages. Over time, liver fibrosis can develop. This is a type of scarring of the liver that can lead to cirrhosis or liver cancer in some patients. International guidelines recommend screening for liver fibrosis in people at increased risk of it, including patients with type 2 diabetes.
“Unfortunately, severe liver disease is often detected late when the prognosis is poor,” says Hannes Hagström, adjunct professor at the Department of Medicine, Huddinge, Karolinska Institutet and consultant in hepatology at the Karolinska University Hospital. “Since there is now an approved treatment for steatotic liver disease with fibrosis, it would be good to be able to screen diabetic patients for liver fibrosis and thus prevent severe disease.”
In Sweden, retina scanning (fundus photography) is an established screening programme to detect eye damage in people with type 2 diabetes. In a new study, Hannes Hagström and his research colleagues investigated whether it would be possible to simultaneously screen for liver fibrosis using elastography. This ultrasound-based technique is painless and takes 5 to 10 minutes to perform.
“This would allow us to kill two birds with one stone and easily detect liver fibrosis in this patient group before it develops into cirrhosis or liver cancer,” says Hannes Hagström. “Our study shows that many patients with type 2 diabetes are willing to undergo such combined screening.”
The researchers asked more than 1,300 patients with type 2 diabetes who underwent retina scanning whether they would also consider having their liver examined by elastography. More than 1,000 people, 77 per cent of the study participants, said yes.
15.8 per cent of patients who had their livers examined by elastography had findings suggestive of liver fibrosis, whereas 5.0 per cent had findings suggestive of advanced liver fibrosis or cirrhosis. However, on repeat examination and reassessment, these figures were lower; 7.4 per cent and 2.9 per cent respectively.
“It shows that the method gives many false positives, partly because many people were probably not fasting as instructed at the first examination,” says Hannes Hagström. “The next step will be to conduct health economic analyses to see if the combined screening strategy for eye and liver disease is beneficial,” he concludes.
The study was conducted in collaboration with the eye clinic Capio Ögon Stockholm Globen. It was mainly funded by the pharmaceutical companies Gilead Sciences and Pfizer, and Region Stockholm.
Hannes Hagström’s research group has received research funding from Astra Zeneca, EchoSens, Gilead, Intercept, MSD, Novo Nordisk and Pfizer. He has also been a consultant or served on advisory committees for Astra Zeneca, Bristol Myers-Squibb, MSD and Novo Nordisk, and has served on review committees for Arrowhead, Boehringer Ingelheim, KOWA and GW Pharma.

Giraffes really struggle with slopes
2024-12-13
New research finds that giraffes much prefer flat terrain and do not traverse slopes of more than 20°, which severely limits the areas in, and outside, protected reserves they can access. The findings, which is are yet to be published, will be presented at the British Ecological Society’s (BES) Annual meeting in Liverpool on the 13th December.
A new study analysing the movements of 33 GPS collared giraffes in South Africa has found that they avoid steep terrain and are unable to navigate slopes with a gradient of more than 20° , most likely due to the energy required and the risk of falling.
The researchers from the University of Manchester ...
Enhancing transverse thermoelectric conversion performance in magnetic materials with tilted structural design
2024-12-13
1. A research team from NIMS and UTokyo has proposed and demonstrated that the transverse magneto-thermoelectric conversion in magnetic materials can be utilized with much higher performance than previously by developing artificial materials comprising alternately and obliquely stacked multilayers of a magnetic metal and semiconductor.
2. When a temperature gradient is applied to a magnetic conductor, a charge current is generated in a direction orthogonal to directions of both temperature gradient and magnetization of the magnetic conductor. This transverse magneto-thermoelectric phenomenon, ...
Durham University scientists unlock secrets of the longest runout sediment flows on earth using seabed seismographs
2024-12-13
-With images-
Durham University scientists have made a groundbreaking discovery in marine geoscience, revealing unprecedented insights into the dynamics of Earth’s longest runout sediment flows.
By using seabed seismographs placed safely outside the destructive paths of powerful underwater avalanches of sediment, researchers have successfully monitored turbidity currents—a natural phenomenon that shapes deep-sea landscapes, damages telecommunication cables, and transports large quantities of sediment and organic carbon to the ocean floor.
The study recorded two massive turbidity ...
Study sheds light on the origin of the genetic code
2024-12-12
Despite awe-inspiring diversity, nearly every lifeform – from bacteria to blue whales – shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.
Taking a fresh approach at an old problem, Sawsan Wehbi, a doctoral student in the Genetics Graduate Interdisciplinary Program at the University of Arizona, discovered strong evidence that the textbook version of how the universal genetic code evolved needs revision. Wehbi is the first author of a study published in the journal PNAS suggesting the order with which amino acids – the code's building blocks –
were recruited is at odds with ...

NIH awards $2.7 million to map retinal connections in degenerative eye disease
2024-12-12
A team of researchers at USC and the University of Utah has received a $2.7 million grant from the National Institutes of Health to map out how an incurable eye disease affects the wiring that powers vision in the eye, in hopes of discovering ways to slow or prevent blindness. Retinitis pigmentosa (RP) is a progressive disease with four known stages that affects the retina, the area at the back of the eye where light is turned into electrical signals that the brain processes to produce sight. The research ...

Illinois historian says Midwest played a crucial role in Black freedom movements worldwide
2024-12-12
CHAMPAIGN, Ill. — The Midwest played a central role in the growth of Black freedom movements in the 20th century. It was a key site for incubating and expanding the ideas of political activist Marcus Garvey, not only in the U.S., but globally, said University of Illinois Urbana-Champaign professor of African American studies and history Erik S. McDuffie.
McDuffie examined the influence of Garvey and the importance of the Midwest in the growth of Black internationalism and radicalism in his new book, “The Second Battle for Africa: Garveyism, the U.S. Heartland and Global Black Freedom.”

New research finds how fighting female flies focus on their foes
2024-12-12
In most research labs, the scientists are on the same page about why they’re pursuing a research project.
But the Rubin Lab at HHMI's Janelia Research Campus isn’t an ordinary research lab.
The lab is examining how aggression affects vision in female fruit flies, but Janelia Senior Group Leader Gerry Rubin doesn’t care too much about the specific answer. Instead, he simply wants to see if the neuroscience research tools that he spent the last decade building are adequate to uncover the underlying mechanisms at play.
Postdoc Katie Schretter, on the other hand, is interested in understanding how neurons in the fly brain ...
