New Analytical Tool Could Replace Traditional Biopsies with Liquid Biopsies for Disease Diagnosis

Biopsies are important clinical tools used to diagnose various diseases or monitor tissues for abnormal growth or transplant rejection. Typically, this involves removing tissue samples from the body for closer examination, which can be invasive depending on the tissue required. Researchers have developed a new analytical method that could enable the use of “liquid biopsies” as an alternative to traditional biopsies for certain patients or diseases. This new tool, developed by researchers from Vanderbilt University’s School of Medicine Basic Sciences (Nashville, TN, USA), is known as EV Fingerprinting, where EV stands for extracellular vesicles. EVs are membrane-bound particles filled with biologically active materials that play a crucial role in cell-cell communication in both health and disease. Although EVs have been studied since the 1980s, their origins and functions have not been fully defined. Research on EVs has intensified over the last two decades, revealing their involvement in processes such as ...

Early Detection of miRNAs in Maternal Blood Could Predict Preeclampsia

Preeclampsia (PE) significantly contributes to increased maternal morbidity and mortality globally, with notably high incidences in the United States where it impacts 2–8% of pregnancies. This condition often leads to premature births and subsequent health issues for infants. Now, a new study indicates that early detection of specific microRNAs (miRNAs) contained in vesicles could enable the prediction of preeclampsia in pregnant individuals before the appearance of clinical symptoms. Conducted by researchers at UCLA Health (Los Angeles, CA, USA), this study highlights the potential of a distinct set of miRNAs within extracellular vesicles (EVs)—small particles that facilitate cellular communication—as a noninvasive biomarker for preeclampsia. The analysis involved 33 participants, including a control group of seven non-pregnant women and a subgroup of 12 women with healthy pregnancies. The study also included 14 women exhibiting symptoms of preeclampsia, emphasizing early detection and prediction. Women with preeclampsia exhibited different levels of miRNAs in EVs ...

AI Identifies Drug-Resistant Typhoid-Like Infection from Microscopy Images within Hours

Antimicrobial resistance is becoming a serious global health concern, making many infections increasingly difficult to treat and limiting available treatment options. This escalation in resistance raises the concern of some infections soon becoming untreatable. A major challenge for healthcare providers is quickly distinguishing between organisms that respond to standard first-line drugs and those that are resistant. Traditional testing methods, which involve culturing bacteria, testing them against various antimicrobial agents, and either manual or machine analysis, can take several days. This delay often leads to the administration of ineffective drugs, which can cause more severe health issues and potentially contribute to the development of further drug resistance. Researchers have now demonstrated that artificial intelligence (AI) can significantly cut down the time needed to accurately diagnose drug-resistant infections. They have developed an algorithm capable of correctly identifying drug-resistant bacteria from microscopy images alone. In research published in Nature Communications, the team of ...

Cohort Study Compares Weight Loss Effects of Tirzepatide vs. Semaglutide

By Don Tracy, Associate Editor JAMA study aims to discover how weight loss differs between patients receiving tirzepatide compared with semaglutide among a clinical population of overweight of obese adults. Tirzepatide and semaglutide are both GLP-1 agonists that have demonstrated the ability to offer significant weight reduction in patients with obesity, with or without type 2 diabetes (T2D). There are currently no real-world data comparing the effectiveness of the two in treating overweight or obese populations. In a cohort study recently published in JAMA Internal Medicine, researchers set out to provide a head-to-head comparison of these medications in a real-world clinical setting, focusing on weight loss outcomes and gastrointestinal adverse events (AEs). The study included 18,386 patients who were new users of tirzepatide or semaglutide with overweight or obesity, regardless of T2D status. Additionally, patients were selected based on their electronic health records data and propensity-score matched to ensure comparability. ...

New Blood Test Aims to Improve Management of Multiple Sclerosis

Multiple Sclerosis (MS) is an autoimmune, inflammatory, and neurodegenerative condition where axonal loss leads to irreversible neurological damage and disability. Currently, approximately 2.8 million people globally are affected by MS, though this figure is likely underestimated due to underdiagnosis in underserved and remote areas lacking adequate neurological care and imaging facilities. While no cure exists for MS, available treatments aim to reduce the frequency of relapses, which are linked to nerve cell damage and the progression of the disease. There is a critical need for an accessible, affordable, and accurate blood test that can detect early signs of neuronal injury and disease activity. The neurofilament light chain (NfL) protein has been identified as a key biomarker for nerve cell damage. Now, a new blood test that measures levels of NfL could facilitate earlier detection of MS-related neuronal injury and improve disease management. Siemens Healthineers (Forchheim, Germany), in collaboration with Novartis ...
