Rapid cyclic stretching induces a synthetic, proinflammatory phenotype in cultured human intestinal smooth muscle, with the potential to alter signaling to adjacent bowel cells.

Background And Aims: Bowel smooth muscle experiences mechanical stress constantly during normal function, and pathologic mechanical stressors in disease states. We tested the hypothesis that pathologic mechanical stress could alter transcription to induce smooth muscle phenotypic class switching.

Methods: Primary human intestinal smooth muscle cells (HISMCs), seeded on electrospun aligned poly-ε-caprolactone nano-fibrous scaffolds, were subjected to pathologic, high frequency (1 Hz) uniaxial 3% cyclic stretch (loaded) or kept unloaded in culture for 6 hours.

Recent advances in treating constipation in children.

Introduction: Functional constipation (FC) is a common childhood condition, diagnosed via the Rome IV criteria. Standard therapy includes lifestyle and dietary modification followed by initiation of osmotic laxative therapy. About 30% of children continue to experience symptoms related to FC despite appropriate management.
