Adherence to the Mediterranean diet and changes in body mass index.

Background: Diet is considered a determinant of weight status, however, more evidence is needed for children. The Mediterranean diet (MedDiet) is one of the healthiest worldwide. This study analyzes the prospective association between adherence to the MedDiet at baseline and changes in standardized body mass index (zBMI) and the incidence of excessive weight.

Certolizumab pegol effectiveness, survival and safety in patients with psoriasis: A multicenter retrospective analysis in daily clinical practice by the Spanish Psoriasis Group.

Background: Certolizumab is an Fc-free PEGylated tumor necrosis factor-alpha (TNFα) inhibitor recently approved for the treatment of moderate-to-severe plaque psoriasis, although there is limited real-world evidence on the effectiveness and safety in patients with plaque psoriasis treated with certolizumab. The objective of this article is to determine the effectiveness, drug survival, and safety, including pregnancy, childbirth, and lactation, of certolizumab in moderate-to-severe plaque psoriasis under real-world conditions.

Methods: This is a retrospective, multicenter, observational study performed in 15 hospitals in Spain.

Deviation from neutral species abundance distributions unveils geographical differences in the structure of diatom communities.

In recent years, the application of metagenomics techniques has advanced our understanding of plankton communities and their global distribution. Despite this progress, the relationship between the abundance distribution of diatom species and varying marine environmental conditions remains poorly understood. This study, leveraging data from the Oceans expedition, tests the hypothesis that diatoms in sampled stations display a consistent species abundance distribution structure, as though they were sampled from a single ocean-wide metacommunity.
