Reporting completeness of nutrition and diet-related randomised controlled trials protocols.

Background And Aims: There is a need to consolidate reporting guidance for nutrition randomised controlled trial (RCT) protocols. The reporting completeness in nutrition RCT protocols and study characteristics associated with adherence to SPIRIT and TIDieR reporting guidelines are unknown. We, therefore, assessed reporting completeness and its potential predictors in a random sample of published nutrition and diet-related RCT protocols.

The role of exclusive enteral nutrition in the pre-operative optimisation of adult patients with Crohn's disease. A systematic review.

Aim: To conduct a systematic review in order to bring together the current knowledge about the use of exclusive enteral nutrition (EEN) in the pre-operative optimisation of adult patients with Crohn's disease undergoing intestinal resection.

Methods: We searched Pubmed, Cochrane Library, ClinicalTrials.gov and the EU clinical trial register to identify experimental and observational studies on the effect of pre-operative EEN on nutritional and clinical outcomes of patients undergoing surgery.

Changes in plasma concentrations of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D during pregnancy: a Brazilian cohort.

Purpose: To characterize the physiological changes in 25-hydroxyvitamin D [25(OH)D] and 1,25-dihydroxyvitamin D [1,25(OH)D] throughout pregnancy.

Methods: Prospective cohort of 229 apparently healthy pregnant women followed at 5th-13th, 20th-26th, and 30th-36th gestational weeks. 25(OH)D and 1,25(OH)D concentrations were measured by LC-MS/MS.

Diet or exercise, or both, for weight reduction in women after childbirth.
