🚨Gut microbiome🦠signatures during acute infection are associated with long #COVID‼️
📢Fascinating study @GutMicrobes @tandfonline🆕🔥
Prof. @KashyapPurna & colleagues @MayoClinicGIHep
🎯#GutMicrobiome signatures during acute #SARSCoV2 infection carry an early signal of subsequent #LongCOVID👏
🎯Among 799 symptomatic outpatients, individuals who later developed Long COVID already displayed a distinct gut microbiome within the first month of infection💡
✳️Symptom-based long COVID sub-phenotypes are associated with distinct gut microbial composition ⏩#GI/sensory & #Fatigue👏

Lately, I keep hearing that IFX is the only drug with clinical trial in perianal Crohn’s...🧐

So, I’ve updated my cheat sheet on medical therapy trials in perianal CD, summarizing 15 RCTs into just one page. Hope it’s useful! Surgical part coming soon

(If any is missing please let me know and I will add it)

💬 Viewpoint: Mass abstract submissions in #MedEd have led to inflated metrics, less meaningful research, and misaligned incentives for trainees and institutions.

IBD management is complex. Support your patients’ decision making by sharing the AGA IBD Drug Guide. This resource, created by IBD specialists, offers ways to filter treatment options to provide recommendations tailored to patient needs. Explore more: https://t.co/uOe7LyOkkW.

Do all dietary emulsifiers have the same impact on the gut❓

@JudithWellens, @vds_julie1, @JoaoPGSabino & colleagues' new findings in healthy people:

✅ An emulsifier-free diet may ⬇ cholesterol levels

✅ Following an emulsifier-free diet + 5 different dietary emulsifiers (one each time):

🔸No changes in gut microbiota diversity

🔸⬇ Short-chain fatty acids, especially in people who consume the food additive carboxymethyl cellulose

🔸No differences in:
👉 Intestinal inflammation (faecal calprotectin, C-reactive protein)
👉 Cholesterol levels

🔸Carragenan ⬆ permeability

💡 The impact of dietary emulsifiers on gut microbiota, intestinal inflammation, and permeability seems to be dependent on the emulsifier

As one food contains more than one emulsifier, it seems prudent to decrease the consumption of foods rich in emulsifiers for better gut health

➡️ Acute pancreatitis-related mortality among US adults has shown an overall decline since 1999. A notable increase in 2020 was likely linked to the COVID-19 pandemic. Significant disparities persist across demographic groups.
