[Home and Ambulatory Artificial Nutrition (NADYA) Group report: home parenteral nutrition in Spain, 2019].

Aim: to communicate the home parenteral nutrition (HPN) data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.com) for the year 2019.

[The NADYA-SENPE Home Enteral Nutrition Registry in Spain: years 2018 and 2019].

Aim: to present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2018 and 2019. Material and methods: from January 1, 2018 to December 31, 2019 the home enteral nutrition registry was recorded, and afterwards a further descriptive and analytical analysis was done. Results: in 2018, 4756 active patients were registered and the prevalence was 101.

Adherence to Mediterranean Diet or Physical Activity After Bariatric Surgery and Its Effects on Weight Loss, Quality of Life, and Food Tolerance.

Objective: To assess whether a healthy dietary pattern or physical activity after bariatric surgery mediates the effects of surgery on weight loss, the quality of life, or food tolerance.

Methods: A prospective observational study conducted in the context of a randomized controlled trial. We assessed the extent to which increasing or decreasing adherence to the Mediterranean diet (MedDiet)-assessed by MEDAS (Mediterranean Diet Adherence Screener)-and of increasing or decreasing physical activity (PA)-assessed with the Short Questionnaire of International PA (IPAQ-Short Q)-after bariatric surgery affected changes in weight, body mass index (BMI), quality of life (Moorehead-Arlet Questionnaire), and food tolerance (Suter test).

Usefulness of Baltasar's expected body mass index as an indicator of bariatric weight loss surgery.

Introduction: Determining the best indicator to report weight loss takes on special relevance following bariatric surgery. Our objective is to apply a method proposed by Baltasar et al. to express weight loss results following bariatric surgery.

[INFLUENCE OF THE NUTRITIONAL COMPOSITION OF DIFFERENT FIBER-ENRICHED ENTERAL NUTRITION FORMULAS ON THE ADMINISTRATION TIME BY GRAVITY AND THE RISK OF TUBE FEEDING OBSTRUCTION].

Introduction: the administration of enteral nutrition by gravity is a very useful method in clinical practice; nevertheless, it may not be very precise. Indeed, this method presents some important limitations, such as the difficulty in establishing a precise dripping rate and the possibility for the dripping rate decrease depending on the formula.

Objectives: assess the administration time and the risk of clogging of 5 fiber-enriched enteral nutrition formulas with different protein concentrations and caloric density, all administered by gravity through nasogastric (NG) tubes of different sizes.
