Impact of Biological Agents on Postsurgical Complications in Inflammatory Bowel Disease: A Multicentre Study of Geteccu.

Background: The impact of biologics on the risk of postoperative complications (PC) in inflammatory bowel disease (IBD) is still an ongoing debate. This lack of evidence is more relevant for ustekinumab and vedolizumab.

Aims: To evaluate the impact of biologics on the risk of PC.

Bryozoa from deep-sea habitats of the northern Gulf of Cádiz (Northeastern Atlantic).

This study examines material collected in the northern part of the Gulf of Cádiz, in the Northeastern Atlantic Ocean, between the Iberian Peninsula and northern Africa, at 300-1200 m depth, within the Site of Community Importance "Volcanes de fango del Golfo de Cádiz" (Mud volcanoes of the Gulf of Cádiz, ESZZ-12002). Several previous studies were carried out in the Iberian Peninsula and Moroccan area (shallow and deep waters), recording ca. 300 bryozoan species from the Gulf of Cádiz.

Spermcast mating with release of zygotes in the small dioecious bivalve Digitaria digitaria.

Digitaria digitaria, a small astartid usually less than 10 mm in length, has a non-brooding behaviour in spite of its limited space for gonad development. This species lives in highly unstable environments with strong currents, which represent a challenge for fertilization and larval settlement. The studied population of D.

Three species of Reteporella (Bryozoa: Cheilostomata) in a diapiric and mud volcano field of the Gulf of Cádiz, with the description of Reteporella victori n. sp.

Diapirs and mud volcanoes (MVs) are formed by the migration and extrusion of fluids and mud to the seafloor, respectively. In the Gulf of Cádiz there are ca. 60 MVs and several diapirs with different environmental conditions and seepage activity.
