Background: The aim of this observational, real-world evidence, modified intention-to-treat (mITT) study based on prospectively collected data from the VEDOIBD registry was to compare the effectiveness of vedolizumab (VEDO) vs antitumor necrosis factor (anti-TNF) in biologic-naïve Crohn's disease (CD) patients.

Methods: Between 2017 and 2020, 557 CD patients starting therapy with VEDO or anti-TNF were consecutively enrolled in 45 IBD centers across Germany. Per study protocol, the analysis excluded biologic-experienced patients and those with a missing Harvey-Bradshaw Index score, resulting in a final sample of 327 biologic-naïve CD patients.

Background: This observational real-world evidence (RWE) study is based on prospectively collected data from the VEDO registry study.

Aim: To compare the effectiveness of vedolizumab and anti-TNF agents in biologic-naïve patients with ulcerative colitis (UC) at the end of induction and during maintenance treatment.

Methods: Between 2017 and 2020, we enrolled 512 patients with UC starting therapy with vedolizumab or an anti-TNF agent in 45 IBD centres across Germany.

When photons interact with matter, forces and torques occur due to the transfer of linear and angular momentum, respectively. The resulting accelerations are small for macroscopic objects but become substantial for microscopic objects with small masses and moments of inertia, rendering photon recoil very attractive to propel micro- and nano-objects. However, until now, using light to control object motion in two or three dimensions in all three or six degrees of freedom has remained an unsolved challenge.
