Objectives: To study nutritional abnormalities in adolescent anorexia nervosa and to establish whether certain abnormalities persist after short-term refeeding.
Method: Sixty-one patients (10-19 years old) admitted to a reference unit for eating disorders between 1999 and 2000 with a diagnosis of anorexia nervosa were evaluated at admission and at discharge. A range of biochemical, nutritional, and hormonal parameters were determined.
Results: At admission, no protein or lipid deficiencies were found, although many patients presented with hormonal abnormalities and red blood cell folate and zinc deficiencies. Hormonal abnormalities reverted significantly (p <.000) after renutrition. There were decreases in erythrocytes and in levels of hemoglobin (p <.000) and folic acid (p <.05). Red blood cell folate and zinc increased but did not reach normal levels.
Conclusions: In a large proportion of adolescent anorexic patients, supplementation of folic acid and zinc is recommended although protein or hormonal replacement does not seem to be necessary.

Unlabelled: Among the restrictive eating and eating disorders, anorexia nervosa (AN) and atypical anorexia nervosa (AAN) are the ones that present the greatest medical complications.
Objective: Describe the characteristics of patients with AN and AAN and their differences in demographic and clinical parameters.
Patients And Method: The records of patients <19 years of age with AN admitted to Clinica Santa María between 2013 and 2019 were reviewed.
TeenGrowth: Individualized Estimations of Weight-Related Risk and Recovery Metrics for Young People With Eating Disorders.

Objective: While weight restoration and/or stabilization is crucial for successful treatment and sustained recovery from restrictive eating disorders (EDs), it is often challenging to define an individual's expected healthy body weight. This paper introduces the TeenGrowth package and its web-based application, designed to calculate and forecast predicted body mass index (BMI) and weight across adolescence.
Method: TeenGrowth includes functions for data cleaning, predicted BMI z-score and BMI calculations, and growth forecasting.
The Influence of Negative Affect on Working Memory Updating of Food Stimuli Among Adolescents With Anorexia Nervosa.

Objective: Difficulty updating information in working memory has been proposed to underlie ruminative thinking in individuals with anorexia nervosa (AN). However, evidence regarding updating difficulties in AN remains inconclusive, particularly among adolescents. It has been proposed that exposure to negative emotion and disorder-salient stimuli may uniquely influence updating in AN.

Introduction: Studies have shown that early weight gain in family-based treatment (FBT) predicts treatment response in adolescents with anorexia nervosa (AN); however, research examining factors associated with early weight gain in FBT is limited. This study tested the feasibility and acceptability of ecological momentary assessment (EMA) in early FBT, particularly to capture momentary data on family climate during mealtimes.
Methods: Using multiple methods, quantitative (EMA) and qualitative (interviews) data were collected in the first 4 weeks of FBT.

Background: There is a need for improved understanding of why 20-30% of individuals with anorexia nervosa (AN) develop a severe and enduring form of illness (SE-AN). Previously, we reported differences in proactive inhibition (a pre-emptive slowing of responses) in individuals with AN compared to healthy controls (after controlling for intolerance of uncertainty). The present study is a preliminary exploration of proactive inhibition in which we compared women with SE-AN with healthy comparison (HC) women and explored its association with restrictive/avoidant eating behaviours.
