As the disease progresses, liver fibrosis and liver-related events (LREs), including hepatocellular carcinoma and other complications, become important indicators of clinical risk. However, accurately assessing fibrosis severity and predicting future LREs remains challenging. Liver biopsy is invasive and costly, while existing noninvasive biomarkers and imaging approaches have limitations. https://medicalxpress.com/news/2026-10-serum-c7-liver-events-metabolic.html Thu, 08 Oct 2026 17:40:07 EDT news710670632 Through long-standing research supported by the National Institutes of Health, investigators at Johns Hopkins Medicine have advanced understanding of ways to better detect invasive aspergillosis (IA).

Many medical practices still ask patients to go without food for 8–12 hours before blood is drawn. While the protocol was originally recommended for glucose and lipid testing, over time, it became the default requirement for almost all routine blood panels. Why it is still followed for such a broad range of routine lab tests is a question that researchers from South Korea asked in a recent study. https://medicalxpress.com/news/2026-10-fast-blood.html Tue, 06 Oct 2026 10:00:21 EDT news710499137 Bloodstream infections are a persistent threat to hospitalized patients, and those caused by fungi are particularly dangerous. Candida species are responsible for most invasive fungal infections worldwide and rank among the leading causes of hospital-acquired bloodstream infections overall. Because different fungal species can respond differently to antifungal drugs, doctors strive to correctly identify the fungus responsible for a given infection before initiating treatment. https://medicalxpress.com/news/2026-10-dna-sequencing-fungal-bloodstream-infections.html Mon, 05 Oct 2026 10:40:10 EDT news710414402 What if checking medication levels were as simple as enjoying a lollipop? A candy-coated device called Lollylab could provide the answer. In ACS Sensors, researchers describe how the lollipop's stem transfers saliva to a sensor that measures acetaminophen levels. https://medicalxpress.com/news/2026-10-candy-coated-lollylab-saliva-medication.html Mon, 05 Oct 2026 09:20:13 EDT news710410561 Glioma brain tumors are diffuse, so surgeons usually cannot excise all of the cancer during surgery. Currently, surgeons remove as much of the tumor as they can and then analyze the tumor's borders after surgery. https://medicalxpress.com/news/2026-10-mass-spectrometry-faster-edges-brain.html Fri, 02 Oct 2026 10:20:01 EDT news710152381 A simple urine test devised by researchers at Stanford Medicine and the VA Palo Alto Health Care System can diagnose bladder cancer more accurately than current standard methods.

The results, published in Scientific Reports, demonstrate the method's potential for faster preliminary screenings in the future. https://medicalxpress.com/news/2026-09-diseases-body-odor-laser-technology.html Tue, 29 Sep 2026 15:20:15 EDT news709911522 New guidance co-led by University of Otago researchers could help more people with suspected inherited diseases receive a clear genetic diagnosis. https://medicalxpress.com/news/2026-09-genetic-guidance-patient-diagnosis-worldwide.html Tue, 29 Sep 2026 13:40:07 EDT news709901942 Minutes count when a patient with a stroke arrives at a hospital emergency room. Doctors stand ready to treat the patient, but whether medication can dissolve the blood clot depends on what the patient is already taking. Even if a blood sample is rushed to the laboratory, results can take up to an hour to arrive. https://medicalxpress.com/news/2026-09-bedside-blood-results-minutes-urgent.html Mon, 28 Sep 2026 16:20:05 EDT news709827121 Aging progressively affects how our bodies function. Among other effects, it reduces the ability of the hematopoietic system—the organs and tissues responsible for producing blood cells—to maintain adequate blood cell production. Understanding and measuring this process is especially important for studying how blood stem cells age and identifying ways to preserve or restore their function. https://medicalxpress.com/news/2026-09-ai-aging-blood-stem-cells.html Mon, 28 Sep 2026 00:00:01 EDT news709558018 A newborn can look perfectly healthy, pass a hearing test and still carry an infection that may affect hearing or development later in childhood. That is the challenge posed by congenital cytomegalovirus, or cCMV, one of the most common infections passed from a mother to a baby during pregnancy. Most babies born with the virus show no obvious signs at birth, making it difficult to know which children may need closer monitoring. https://medicalxpress.com/news/2026-09-routine-newborn-screening-cytomegalovirus-infections.html Sun, 27 Sep 2026 17:00:06 EDT news709467087 A test that compares the levels of two molecules in the blood can accurately distinguish between bacterial and viral infections in newborn babies with fever, according to a small study presented at the European Emergency Medicine Congress. https://medicalxpress.com/news/2026-09-blood-newborns-fever-bacterial-viral.html Sat, 26 Sep 2026 18:00:02 EDT news709464072 Scientists and doctors at Newcastle are among the first in the U.K. to use a pioneering brain tumor test with the potential to speed up diagnosis for patients—from weeks to hours. https://medicalxpress.com/news/2026-09-brain-tumor-diagnosis-treatment.html Fri, 25 Sep 2026 13:40:07 EDT news709558441 A test developed by researchers at the Garvan Institute of Medical Research has identified the genetic cause of inherited muscle disease in people who remained without answers after years, sometimes decades, of standard testing.
