(Press-News.org) BETHESDA, MD (April 25, 2025) — Scientists have identified five specific blood proteins that can accurately predict a person’s risk for developing a serious form of liver disease as early as 16 years before they experience symptoms, enabling early intervention and possible prevention and treatment, according to a study to be presented at Digestive Disease Week® (DDW) 2025.
The findings address metabolic dysfunction-associated steatotic liver disease (MASLD), which has become the most common form of liver disease worldwide and is continuing to increase. People with MASLD face up to twice the mortality rate of those without the disease.
“Imagine if we could predict risk of MASLD years before it starts,” said Shiyi Yu, MD, resident physician in the department of gastroenterology, Guangdong Provincial People's Hospital in China. “Too often, people do not find out they are at risk for liver disease before they are diagnosed and coping with symptoms. The field urgently needs effective biomarkers and predictive models, and our research shows that plasma proteins offer novel potential strategies for early prediction and intervention.”
Researchers analyzed blood samples from more than 50,000 participants in the UK Biobank. They followed their health records for more than 16 years, identifying levels and combinations of proteins in the blood associated with developing liver disease later in life. Screening more than 2,700 proteins, they found five — CDHR2, FUOM, KRT18, ACY1, and GGT1 — that appear to be early warning signals for MASLD. The combined levels of these five proteins achieved 83.8% accuracy at predicting disease five years from onset and 75.6% accuracy at predicting 16 years ahead of diagnosis. Adding clinical biomarkers such as body mass index and daily exercise amount to the protein levels achieved even greater accuracy of 90.4% at five years and 82.2% at 16 years.
“We achieved similar results when we tested this predictive model in a separate cohort of people in China, further supporting the robustness of the model and showing it can be effective across diverse populations,” Dr. Yu said.
As an observational study, the research does not demonstrate a causal connection between the plasma proteins and the development of liver disease. Further research is underway to explore possible pathways.

Digestive Disease Week® (DDW) is the largest international gathering of physicians, researchers, and academics in the fields of gastroenterology, hepatology, endoscopy, and gastrointestinal surgery. Jointly sponsored by the American Association for the Study of Liver Diseases (AASLD), the American Gastroenterological Association (AGA), the American Society for Gastrointestinal Endoscopy (ASGE) and the Society for Surgery of the Alimentary Tract (SSAT), DDW is an in-person and online meeting from May 3-6, 2025. The meeting showcases nearly 6,000 abstracts and more than 1,000 lectures on the latest advances in GI research, medicine, and technology. More information can be found at www.ddw.org

Cutting-edge DNA mapping technology identified new genetic information that can help researchers decipher more genetic diseases, a new study found. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
The technology identified more genomic imprinting in DNA—10 times as much—than previously published data. Genomic imprinting occurs when only one parent’s gene is expressed in a child’s genetic makeup, which contributes to rare pediatric diseases, ...
Taking antibiotics within the first two years of life is linked to a higher body mass index (BMI) in childhood, according to a new study. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Researchers found that children exposed to antibiotics in the first two years of life had a 0.067 higher BMI adjusted for age and sex, a 9% greater risk to be overweight, and a 20% greater risk to be obese than children who were unexposed.
Researchers found no correlation between BMI and antibiotic use before pregnancy, during pregnancy, or at birth.
Antibiotics ...
Artificial intelligence (AI) can help better identify prevalence of physical abuse of children seen in the emergency room, a new study found. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Researchers used a machine-learning model to estimate instances of child abuse seen in emergency departments based on diagnostic codes for high-risk injury and physical abuse. The researchers’ approach better predicted abuse rates than those that rely solely on diagnostic codes entered by a provider or administrative staff. Relying on abuse codes alone ...
Pregnant women living with opioid use disorder (OUD) and their infants had significantly better health outcomes when treated with buprenorphine, according to a new study at Vanderbilt University Medical Center and Emory University’s Rollins School of Public Health. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Pregnant women who received buprenorphine, a medication used to treat OUD, were less likely to have a preterm birth, face serious health complications, or have their infants hospitalized in the NICU compared to those ...
More information about gun safety has increasingly led parents to ask about firearms in the homes their kids visit, according to a new national study. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Every new source of information increased parents’ likelihood of asking by 40%. Researchers found that 16% of caregivers who had never received firearm safety information asked about firearms where their child was visiting, compared to 79% of those who had ...
Erythropoietin, a treatment for newborns with critically low levels of oxygen or blood supply to the brain at birth, does not prevent death or disability, according to a new multinational study. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Researchers found that a high-dose treatment with erythropoietin, paired with standard cooling treatments, does not reduce death, rate of cerebral palsy, or physical or cognitive impairment ...
Young children with chronic conditions are more likely to be hospitalized for respiratory syncytial virus (RSV) than healthy children, according to a new study. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
Toddlers with chronic conditions are hospitalized for RSV at twice the rate as healthy toddlers over their first two seasons. The risk was highest for children born very prematurely under 28 weeks of gestation, or with conditions affecting multiple organs, the lungs, heart, or digestive system.
Researchers recommend that children with those specific conditions ...
Children treated with primary care telehealth visits were less likely to receive antibiotics for acute respiratory tract infections than those examined in person, according to a new study. The research will be presented at the Pediatric Academic Societies (PAS) 2025 Meeting, held April 24-28 in Honolulu.
While providers prescribed 12% fewer antibiotics during initial primary care telehealth visits compared to in-person appointments, both settings had similarly high rates of following established guidelines, according to researchers. In the two weeks after the initial ...
Energy scarcity is a central driver of animal behavior and evolution. The amazing diversity of life on this planet is a testament to the plethora of novel biological solutions to the problem of securing and maintaining energy. However, despite being so central to biology, it remains difficult to quantify, and thereby empirically analyze, energy consumption.
While organisms use energy for a very wide variety of processes – from growth to cognition – one activity is a major drain for many animals: movement. For highly mobile animals, movement is as such a powerful lens through which to estimate ...
Mapping soybean cultivation with high precision is crucial for maximizing agricultural productivity and ensuring food security. However, conventional methods often struggle with regional inconsistencies and require extensive datasets. A breakthrough study has introduced the Spectral Gaussian Mixture Model (SGMM), a novel approach that leverages key physiological traits—such as chlorophyll content and canopy greenness—to dramatically enhance classification accuracy. Validated across four major soybean-producing regions, SGMM sets a new standard for global crop monitoring, offering a scalable, efficient, and ...
