Objective: Long-term evidence on ustekinumab treatment response and persistence in patients with Crohn's disease in a real-world setting is scarce. We performed a retrospective nationwide chart review study of long-term clinical outcomes in Crohn's disease patients treated with ustekinumab.

Methods: The study was conducted in 17 Finnish hospitals and included adult Crohn's disease patients who received an initial intravenous dose of ustekinumab during 2017-2018.

Purpose: To study liver P MRS, histology, transient elastography, and liver function tests in patients with virus C hepatitis (HCV) or autoimmune hepatitis (AIH) to test the hypothesis that P MR metabolic profile of these diseases differ.

Materials And Methods: 25 patients with HCV (n=12) or AIH (n=13) underwent proton decoupled P MRS spectroscopy performed on a 3.0T MR imager.

Background: Liver biopsy is the gold standard in evaluating inflammation and fibrosis in autoimmune hepatitis.

Aims: In search of non-invasive follow-up tools in autoimmune hepatitis, we evaluated phosphorus magnetic resonance spectroscopy (P MRS).

Methods: Twelve consecutive AIH patients (mean age 42.

Objectives: Oxidative stress (OS) is an essential element in the pathogenesis of Barrett's esophagus (BE) and its transformation to adenocarcinoma (EAC). The state of OS in the proximal stomach of patients with BE and EAC is unknown. Isoprostanes are a specific marker of OS not previously used to determine OS from BE/EAC tissue samples.

Objective: Interferon-free therapy for hepatitis C virus (HCV) infection is costly, and therefore patients with advanced fibrosis are prioritized. Although coupled with considerable side effects, a large proportion of genotype 2/3 infected patients achieve a sustained virological response (SVR) following interferon-based therapy. The present study evaluates experimental clinical trial and verifying real-life data with the aim of identifying patients with a high likelihood of favorable outcome following short interferon-based treatment.
