Clinical effectiveness of bidirectional fecal microbiota transfer in the treatment of recurrent Clostridioides difficile infections.

Background: Fecal microbiota transfer (FMT) has become a standard of care in the prevention of multiple recurrent Clostridioides difficile (rCDI) infection.

Aim: While primary cure rates range from 70-80% following a single treatment using monodirectional approaches, cure rates of combination treatment remain largely unknown.

Methods: In a retrospective case-control study, outcomes following simultaneous bidirectional FMT (bFMT) with combined endoscopic application into the upper and lower gastrointestinal tract, compared to standard routes of application (endoscopy via upper or lower gastrointestinal tract and oral capsules; abbreviated UGIT, LGIT and CAP) on day 30 and 90 after FMT were assessed.

Spin stress contribution to the lattice dynamics of FePt.

Invar-behavior occurring in many magnetic materials has long been of interest to materials science. Here, we show not only invar behavior of a continuous film of FePt but also even negative thermal expansion of FePt nanograins upon equilibrium heating. Yet, both samples exhibit pronounced transient expansion upon laser heating in femtosecond x-ray diffraction experiments.

Fecal Eosinophil Cationic Protein Is a Diagnostic and Predictive Biomarker in Young Adults with Inflammatory Bowel Disease.

Background And Aims: Fecal biomarkers are important non-invasive markers monitoring disease activity in inflammatory bowel disease (IBD). We compared the significance of fecal eosinophil cationic protein (fECP) and fecal calprotectin (fCal).

Methods: fECP and fCal were measured in patients with Crohn's disease (CD, n = 97), ulcerative colitis (UC, n = 53), Clostridioides difficile infection (CDI, n = 9), primary food allergy (PFA, n = 11), pollen-associated food allergy (n = 25) and non-inflammatory controls (n = 78).

Macrophage-Specific NF-κB Activation Dynamics Can Segregate Inflammatory Bowel Disease Patients.

The heterogeneous nature of inflammatory bowel disease (IBD) presents challenges, particularly when choosing therapy. Activation of the NF-κB transcription factor is a highly regulated, dynamic event in IBD pathogenesis. Using a lentivirus approach, NF-κB-regulated luciferase was expressed in patient macrophages, isolated from frozen peripheral blood mononuclear cell samples.
