Two multitarget stool tests currently in development have shown promising results for colorectal cancer (CRC) screening in average-risk individuals. The first test, a multitarget stool RNA test (mt-sRNA; Colosense, Geneoscopy), was compared to colonoscopy for detecting advanced adenomas and CRC in individuals aged 45 and older. The second test, a next-generation multitarget stool DNA (mt-sDNA; Cologuard, Exact Sciences), was evaluated alongside a fecal hemoglobin assay for CRC screening in adults aged 40 and older. Key Findings:

In a podcast episode on KevinMD, Brian Hudes, a gastroenterologist, delves into the changing dynamics of the gastroenterology field in the United States. The discussion touches upon historical decisions that have shaped the specialty, the evolving demographics of the workforce, and the implications these shifts have on physician salaries. Hudes highlights the challenges faced by professionals in the field and explores potential solutions to address them. The overarching theme of the podcast revolves around understanding the multifaceted factors that are molding the future of gastroenterology. Key Takeaways:
ChatGPT 4.0, a chatbot, has demonstrated an overall accuracy of 80% in answering questions related to irritable bowel syndrome (IBS). This assessment was based on a study conducted by Dr. Anthony Lembo and his team at the Cleveland Clinic’s Digestive Disease Institute. The researchers used Google Trends to identify IBS-related searches from the past five years and formulated 15 questions based on these queries. These questions were then input into ChatGPT 4.0, which was also asked to provide references for its answers. Key Findings:
GI OnDEMAND®, a leading multidisciplinary virtual care platform in gastroenterology, has announced a collaboration with GI Psychology LLC. This specialized group practice comprises behavioral health clinicians who are experts in treatments for gastrointestinal disorders. The partnership aims to provide scientifically supported GI psychology services to ACG members and patients with gastrointestinal health conditions across the nation. Key Points:
Body Mass Index (BMI) has been a longstanding tool in clinical practice for categorizing patients as “underweight,” “overweight,” or “obese.” However, its effectiveness as a standalone measure for obesity is being increasingly questioned. Dr. Fatima Cody Stanford, an obesity medicine physician scientist at Massachusetts General Hospital and Harvard Medical School, points out that BMI is a crude number that doesn’t provide insights into an individual’s actual weight composition, such as fat mass, muscle mass, or weight distribution. Key Points:
A new blood test, named the Galleri liquid biopsy, has been introduced to the market, offering the potential to detect early signs of cancer. Priced at $949, the test claims to screen for over 50 types of cancers by identifying a common cancer signal present in DNA fragments released by tumors into the bloodstream. Since its launch in June 2021, Grail, the company behind Galleri and a subsidiary of gene-sequencing firm Illumina, has reported sales of more than 130,000 prescription-only tests. However, the medical community appears divided on the test’s current utility, with some expressing excitement about its potential, while…
GigXR, Inc., a leading provider of holographic healthcare training, has announced a collaboration with the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine). This partnership aims to introduce a new gastrointestinal module for the HoloScenarios application, designed to enhance the training of medical and nursing students in diagnosing and treating acute gastrointestinal diseases. The HoloScenarios: Gastrointestinal module offers evidence-based clinical simulations featuring hyperrealistic holographic simulated patients and medical equipment, accessible from anywhere globally. Key Highlights:
In 2023, prior authorization has emerged as a significant concern in the field of gastroenterology. Dr. Benjamin Levy III, a gastroenterologist at the University of Chicago Medicine, discussed the challenges posed by prior authorizations in an interview with Becker’s. He highlighted several key points: In summary, while prior authorizations aim to ensure appropriate care, they also introduce administrative challenges that can hinder timely patient care and increase costs.
Artificial intelligence (AI) already is making a difference in healthcare by helping medical professionals interpret tests, clarify diagnoses and identify the most effective treatment approaches to a range of diseases. As Cedars-Sinai explores new uses of AI, it is balancing the rapid development of this emerging technology with responsible and ethical implementation. “AI systems have the power to transform healthcare,” said Mike Thompson, vice president of Enterprise Data Intelligence at Cedars-Sinai. “If implemented properly and responsibly, AI can be deployed to enhance patient experience, improve population health, reduce costs and improve the work life of healthcare providers.” Thompson sat down…
A next-generation, multitarget stool DNA test, known as the next-generation Cologuard, has demonstrated a 94% sensitivity and 91% specificity in detecting colorectal cancer, surpassing the performance of fecal immunochemical testing (FIT). Thomas F. Imperiale, MD, from Indiana University Medical Center, highlighted that this version of Cologuard differs from FIT due to its unique markers, which are all methylated DNA markers. In the BLUE-C study, which involved 26,758 participants, the next-generation Cologuard showed a higher likelihood of detecting cancer (94% vs. 67%) and precancerous lesions (43% vs. 23%) compared to FIT. Imperiale emphasized the significance of the improved specificity, which is…
