Results of the national registry of patients diagnosed with inflammatory bowel disease candidates for bariatric surgery (ReNacEIBar).

BACKGROUND: Our aim is to carry out a national registry of patients with inflammatory bowel disease (IBD) who underwent bariatric surgery, as well as evaluate the results and management of this type of patients in the usual clinical practice. METHODS: National multicentric observational retrospective study, including patients, previously diagnosed with IBD who underwent bariatric surgery from January 2000 to December 2022. RESULTS: Forty-one patients have been included: 43,9% previously diagnosed with ulcerative colitis, 57,3% Crohn's disease, and an indeterminate colitis (2,4%). The preoperative BMI was 45.8 ± 6,1 kg/m2. Among the bariatric surgeries, 31 (75,6%) sleeve gastrectomy, 1 (2,4%) gastric bypass and 9 (22%) one anastomosis gastric have been carried out. During the postoperative period, 9.8% complications have been recorded. BMI was 29,5 ± 4,7 kg/m2 and percent total weight lost was 33,9 ± 9,1% at 12 months. CONCLUSIONS: Bariatric surgery in patients with inflammatory bowel disease can be considered safe and effective.

Proteomics of foodborne trematodes.

Food-borne trematodiases are among the most neglected tropical diseases, not only in terms of research funding, but also in the public media. The Trematoda class contains several species identified as the causal agents of these diseases whose biological cycle, geographical distribution and epidemiology have been well characterised. The diagnosis of these diseases is based on parasitological techniques and only a limited number of drugs are currently available for treatments, most of which are unspecific. Therefore, in-depth studies to identify new and specific targets for both effective diagnosis and treatments are urgently needed. Currently, little molecular information is available regarding the host-parasite interaction. In this regard, proteomic studies have the potential to identify diagnostic biomarkers for the early detection of the diseases, as well as new vaccine targets. In this review, a description of the biology, clinical features and current diagnostic tools of the main groups of trematodes and the corresponding diseases they cause is followed by a discussion of the available studies using proteomic techniques to identify key parasite proteins involved in the pathogenesis of food-borne trematodiases.
