Vaccines and IBD: What the Guidelines Say About Timing Around Biologics and Immunosuppression
For people with inflammatory bowel disease on immunosuppressive treatment, vaccination is a planned, timing-sensitive part of care. International guidelines agree on a few clear principles: sort out vaccines early, give live vaccines before treatment where possible, and rely on inactivated vaccines once treatment has started.

Anti-TNF Drugs for Children With Crohn's Disease: What a 2025 Cochrane Systematic Review Found
A 2025 Cochrane systematic review examined the randomised controlled trial evidence on tumour necrosis factor-alpha antagonists, including infliximab and adalimumab, for treating Crohn's disease in children and adolescents, a population in which treatment decisions carry particular weight given the needs of a developing body.

Can IBD Affect Memory and Thinking? A 2026 Systematic Review of 66 Studies Investigates
A systematic review published in the Journal of Crohn's & Colitis in May 2026 searched PubMed and Scopus through August 2024, analysing 66 studies from population research, genetic investigations, and preclinical models, and found that patients with IBD may exhibit impaired cognitive function, particularly in memory, attention, and executive processing, with disease activity, chronic inflammation, and psychological stress among the contributing factors identified.

The Gut-Brain Axis in IBD: What a 2026 Systematic Review of 1,040 Patients Found About Microbiota and Mood
A systematic review published in Frontiers in Microbiology in June 2026 analysed ten studies involving 1,040 IBD patients and found that anxiety and depressive symptoms were associated with reduced gut microbial diversity and enrichment of pro-inflammatory bacterial taxa, with authors concluding the relationship may be bidirectional.

Beyond the Bowel: What a 2025 Cochrane Review Found About Psychological Interventions in IBD
A 2025 Cochrane systematic review and meta-analysis by Tiles-Sar and colleagues examined the randomised trial evidence for psychological interventions in inflammatory bowel disease, assessing whether approaches such as cognitive behavioural therapy, mindfulness, and stress management affect disease activity, quality of life, and psychological wellbeing.

Learning to Live With IBD: What a Cochrane Review Found About Patient Education Programs
A 2023 Cochrane systematic review examined the trial evidence for structured patient education interventions in inflammatory bowel disease, assessing whether programmes delivered by nurses, clinicians, or digital tools affect disease activity, quality of life, and patients' ability to manage their own condition.

Ageing With an Ostomy: Six Domains the Research Says Matter Most for Home Self-Management
A 2026 evidence summary published in Frontiers in Medicine reviewed 15 high-quality studies on home self-management for elderly ostomy patients and synthesised 36 evidence-based recommendations across six care domains, from stoma assessment to medication management.

Coming Home With an Ostomy: What the Evidence Says About the Weeks After Discharge
A 2026 best evidence summary published in the Asia-Pacific Journal of Oncology Nursing reviewed the research on post-discharge follow-up for colorectal cancer patients with a new ostomy, examining which components of structured support in the first weeks at home are backed by published evidence.

What You Drink and IBD Risk: A 2026 Dose-Response Meta-Analysis Advances the Evidence
A 2026 systematic review and dose-response meta-analysis pooled data across multiple studies to map how different beverage types, from coffee and tea to alcohol and sweetened drinks, relate to the risk of developing inflammatory bowel disease.

Before Your Stoma Reversal: What a Cochrane Review of 9 Trials Found About Wound Closure and Infection Risk
A 2024 Cochrane systematic review and meta-analysis of nine randomised controlled trials found that purse-string skin closure during stoma reversal cuts the surgical site infection rate to roughly one-fifth of that seen with conventional linear closure — a finding worth discussing with your surgical team.

High-Output Stoma: Five Evidence-Based Strategies and the Electrolyte Risks That Make Prompt Management Essential
A 2026 systematic review of 15 studies maps five categories of intervention for high-output stomas — and names the electrolyte imbalances that, left unmanaged, can lead to kidney injury and preventable readmission.

What the 2026 AGA hemorrhoid update says — and why not every anal symptom is a hemorrhoid
A new American Gastroenterological Association Clinical Practice Update puts fibre, fluids and not straining first for symptomatic hemorrhoids, reserves procedures and surgery for higher grades — and is a reminder that bleeding from the bottom should be checked, not assumed.

Negative-Pressure Wound Dressings After Stoma Reversal: What Seven Randomised Trials Found
A 2026 GRADE-based systematic review and meta-analysis of seven randomised controlled trials compared negative-pressure wound therapy (NPWT) with conventional dressings after stoma reversal surgery, examining surgical site infection rates and healing outcomes.

Which Biologic Medicines Help Crohn's Disease Remission? A 2026 Cochrane Network Review Compares Them All

A 2024 Cochrane systematic review and meta-analysis compared two techniques for closing the skin wound after stoma reversal and found that one approach was associated with a significantly lower rate of surgical site infection.

Skin Problems Around the Stoma: What a 2026 Systematic Review Found About Who Is at Risk
A 2026 systematic review and meta-analysis in Frontiers in Medicine examined risk prediction models for moisture-associated skin damage in the peristomal area, identifying the factors most consistently linked to skin breakdown in people living with a stoma.

Stigma After Stoma Surgery: What a 2026 Evidence Review Found About Screening and Support
A 2026 literature review in Frontiers in Oncology identified approaches to detecting felt stigma in colorectal cancer patients with stomas and summarised evidence on which interventions provide meaningful support.

Digital Health Tools for Ostomy Patients: What a 2026 Systematic Review Found
