2025 Gut Microbiota for Health World Summit to spotlight groundbreaking research

Summit to showcase the latest microbiome research on coronavirus, plant and dairy-based protein, as well as probiotics

2025-03-15

(Press-News.org) Bethesda, MD (March 12, 2025) — The 13th Gut Microbiota for Health World Summit, taking place March 15-16 in Washington, D.C., will reveal how cutting-edge research on gut microbiome science is being applied to clinical practice. The event – organized by the American Gastroenterological Association (AGA) and the European Society of Neurogastroenterology and Motility (ESNM) – will bring together clinicians, researchers, nutritionists, and dietitians from around the world.

Top studies being presented:

COVID-19 impacts gut bacteria in children

Study title: Persistent gut microbiome dysbiosis and elevated fecal biomarkers in children PostSARS CoV-2 infection experiencing prolonged gastrointestinal and neuropsychiatric symptoms

A novel study found that the gut microbiome in children is altered post-COVID-19 infection, much like it is in adults. Researchers found a significant decrease in beneficial bacteria, like Lacticaseibacillus and Bifidobacterium, in children who had COVID-19 compared to those who didn’t. These bacteria help reduce inflammation and support gut health. Children with lingering symptoms also showed different types of bacteria, in addition to elevated markers of inflammation and decreased barrier function in the gut. Future research will examine immune responses and potential microbiome-targeted therapies for persistent post-COVID-19 symptoms.

Dietary protein may support gut health

Study title: A novel role for S100B in diet and gut-microbiota regulation

Researchers analyzed 35 plant-based and 23 dairy-based foods and found that nearly 50% of tested plants and milk and dairy products contain S100B, a helpful protein that binds calcium. The study suggested that S100B may interact with gut bacteria to promote a healthy microbiome, potentially influencing inflammatory bowel disease (IBD). The findings open the door for future dietary applications, such as using S100B in supplements and nutraceuticals.

Probiotics reduce post-colonoscopy discomfort

Study title: Efficacy of probiotics in reducing post-colonoscopy gastrointestinal symptoms: a meta-analysis of randomized controlled trials

A meta-analysis of 10 studies, including 2,345 patients, showed that probiotics significantly reduced abdominal pain, bloating, and vomiting after a colonoscopy. While there was no significant reduction in nausea, constipation, gas, or diarrhea, these findings suggest probiotics could improve patient recovery and encourage more individuals to undergo the crucial procedure.

International survey finds that support for climate interventions is tied to being hopeful and worried about climate change

2025-03-15

A global survey of more than 30,000 people in 30 countries has revealed how people around the world feel about climate change, and how those emotions relate to perceptions of and support for climate interventions that could address the crisis. The new study is published in the journal Risk Analysis. To investigate the intensity of “climate emotions” on a global scale and their intersection with perceptions of climate interventions, a team of researchers at Aarhus University in Denmark and the International Institute for Applied Systems Analysis (IIASA) in Austria conducted an online survey in 19 different ...

Cambridge scientist launches free VR platform that eliminates the fear of public speaking

2025-03-15

Today is World Speech Day, a day where we are called upon to embrace public speaking opportunities. Unfortunately, this call to action is unlikely to be widely embraced given that the majority of people are affected by speech anxiety and the fear of public speaking. Fortunately, however, there is now a free and highly effective solution. At Lucy Cavendish College, University of Cambridge, researchers are using emerging digital technology to enrich and accelerate learning. Their Immersive Technology Lab received a national innovation award for a project that uses VR to better translate ...

Open-Source AI matches top proprietary model in solving tough medical cases

2025-03-15

Artificial intelligence can transform medicine in a myriad of ways, including its promise to act as a trusted diagnostic aide to busy clinicians. Over the past two years, proprietary AI models, also known as closed-source models, have excelled at solving hard-to-crack medical cases that require complex clinical reasoning. Notably, these closed-source AI models have outperformed open-source ones, so-called because their source code is publicly available and can be tweaked and modified by anyone. Has open-source AI caught up? The answer appears to be yes, at least when it comes to one such open-source AI model, according to the findings ...

Good fences make good neighbors (with carnivores)

2025-03-15

A predator’s gotta eat, but sometimes what they eat harms people sharing the landscape, and that often leads to the carnivore’s death. Fortified corrals are one strategy used in Tanzania to protect both livestock and vulnerable carnivore species. But then where do lions, leopards and hyenas go for dinner? Do they feed on the next herd over? A new study led by Colorado State University has found that good fences truly do make good neighbors because fortified enclosures also benefit livestock keepers who live nearby. Instead of dining on easier meals next-door and negatively impacting neighbors who don’t ...

NRG Oncology trial supports radiotherapy alone following radical hysterectomy should remain the standard of care for early-stage, intermediate-risk cervical cancer

2025-03-15

Results from the NRG Oncology GOG-0263 phase III clinical trial testing the addition of cisplatin-based chemotherapy to adjuvant radiotherapy following radical hysterectomy and lymphadenectomy for patients with early-stage, intermediate-risk cervical carcinoma indicated that the addition of chemotherapy did not improve outcomes for patients and led to increased toxicity for patients. The outcomes of this trial support the use of the current standard of care using adjuvant radiotherapy alone following surgery. These results were ...

Sharks are dying at alarming rates, mostly due to fishing. Retention bans may help

2025-03-14

Despite the fear they may inspire in humans, sharks have far more reason to fear us. Nearly one-third of sharks are threatened with extinction globally, mostly as a result of fishing. A team led by researchers at UC Santa Barbara discovered that mandates to release captured sharks won’t be enough to prevent the continued decline of these important ocean predators. These findings, published in Fish & Fisheries, highlight the importance of monitoring shark populations and combining different strategies for managing their numbers. Some ...

New CRISPR-based diagnostic test detects pathogens in blood without amplification

2025-03-14

Bioengineering professor and The Grainger College of Engineering’s Dean, Rashid Bashir, led a team of researchers in a project that’s resulted in new technology that offers rapid, highly sensitive detection of multi-drug-resistant bacteria and other pathogens at low concentrations. This research was featured in an article in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). Researchers designed a CRISPR-based test that rapidly detects low levels of pathogen genetic material in blood. This is done without the need for nucleic acid amplification. In ...

Immunotherapy may boost KRAS-targeted therapy in pancreatic cancer

2025-03-14

PHILADELPHIA – Adding immunotherapy to a new type of inhibitor that targets multiple forms of the cancer-causing gene mutation KRAS kept pancreatic cancer at bay in preclinical models for significantly longer than the same targeted therapy by itself, according to researchers from the Perelman School of Medicine at the University of Pennsylvania and Penn Medicine’s Abramson Cancer Center. The results, published in Cancer Discovery, prime the combination strategy for future clinical trials. Combatting the “undruggable” ...
