Abstract
Background: nutritional support (NS) is a core element in the treatment of underweight patients with anorexia nervosa (AN). Objective: to analyze the adherence of NS prescriptions to clinical practice guidelines (CPGs) for AN patients and to compare the effectiveness, safety, and cost of NS according to adherence. Methods: this retrospective observational study included AN patients admitted to an Eating Disorders Unit between January 2006 and December 2009 and followed until December 2014. NS prescriptions were compared with guidelines published by the American Psychiatric Association (APA), the National Institute for Clinical Excellence (NICE), and the Spanish Ministry of Health and Consumption (SMHC). Adherence was defined as percentage of hospitalizations that followed all recommendations. Results: adherence to APA and NICE/SMHC was observed in 10.2% and 73.4%, respectively, of the total of 177 hospitalizations. Body weight and body mass index were higher at admission in the NICE/SMHC adherence versus non-adherence group (p < 0.001). Weight gain rate during hospitalization was higher (p = 0.009) in "APA adherence" (135.5 g/day) versus "non-adherence" (92.1 g/day) group. Hospital stay was significantly shorter (p = 0.025) in "NICE/SMHC adherence" (39.5 days) versus "non-adherence" group (50.0 days). NICE/SMHC adherence was associated with lower costs (p = 0.006). Conclusions: NS prescriptions for anorexic patients more frequently followed NICE/SMHC than APA recommendations. Over the short-term, APA adherence was associated with improved weight gain. Patients adhering to NICE/SMHC recommendations had shorter hospital stay and reduced costs, likely due to their more favorable nutritional status at admission.

Abstract
BACKGROUND Bone health and growth during adolescence require adequate total body protein (TBPr). Renutrition for patients with anorexia nervosa (AN) should aim to normalize body composition and to recover both fat mass and TBPr. OBJECTIVE We intended to analyze predictors of protein status, including exercise status, in adolescents with AN and to investigate whether weight gain would replenish body protein deficits. METHODS We assessed TBPr in a longitudinal, observational study as height-adjusted nitrogen index (NI) using in vivo neutron activation analysis in 103 adolescents with AN [mean ± SD age, 15.6 ± 1.4 y; body mass index (BMI, in kg/m2), 16.5 ± 1.6] at the commencement of inpatient refeeding (T0), in 56 of these patients 7 mo thereafter as outpatients (T1), and in age-matched controls (C; n = 51, 15.5 ± 2.1 y, BMI 20.7 ± 1.9). Lean tissue and fat mass were assessed by dual-energy X-ray absorptiometry. BMI, BMI standard deviation score, and lean tissue mass were tested as predictors of protein status using receiver operating characteristic analysis. RESULTS At T0, NI was decreased in AN (AN, 0.88 ± 0.10 compared with C, 1.00 ± 0.08, P < 0.001). In 34%, the patients showed protein depletion. Patients classified as ``exercisers'' had a higher NI than did ``nonexercisers'' (0.89 ± 0.11 compared with 0.85 ± 0.08, P = 0.045). BMI, BMI standard deviation score, and lean tissue mass did not show potential as predictors of protein status. Despite increases in weight (+6.9 ± 4.5 kg), and BMI (+2.5 ± 1.7), protein status did not improve (TBPr T0, 8.0 ± 1.1 kg; T1, 8.1 ± 1.0 kg, P = 0.495). In an AN subgroup at 7 mo matched with controls in age (AN, 16.5 ± 1.1 y; C, 16.2 ± 1.8 y) and BMI (AN, 20.5 ± 1.4; C, 20.7 ± 1.3), protein status was still not normalized in AN (NI: AN, 0.89 ± 0.09 compared with C, 1.00 ± 0.07, P < 0.001). CONCLUSIONS Adolescents recovering from AN remained protein depleted at 7 mo after baseline assessment, even though they were weight restored.

Abstract
BACKGROUND Anorexia nervosa is a common psychiatric disorder in adolescence and is related to cardiovascular complications. Our aim was to study the effect of anorexia nervosa on metabolic parameters, leucocyte-endothelium interactions, adhesion molecules and proinflammatory cytokines. MATERIALS AND METHODS This multicentre, cross-sectional, case-control study employed a population of 24 anorexic female patients and 36 controls. We evaluated anthropometric and metabolic parameters, interactions between leucocytes polymorphonuclear neutrophils (PMN) and human umbilical vein endothelial cells (HUVEC), proinflammatory cytokines such as tumour necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) and soluble cellular adhesion molecules (CAMs) including E-selectin, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1). RESULTS Anorexia nervosa was related to a decrease in weight, body mass index, waist circumference, systolic blood pressure, glucose, insulin and HOMA-IR, and an increase in HDL cholesterol. These effects disappeared after adjusting for BMI. Anorexia nervosa induced a decrease in PMN rolling velocity and an increase in PMN rolling flux and PMN adhesion. Increases in IL-6 and TNF-α and adhesion molecule VCAM-1 were also observed. CONCLUSIONS This study supports the hypothesis of an association between anorexia nervosa, inflammation and the induction of leucocyte-endothelium interactions. These findings may explain, in part at least, the increased risk of vascular disease among patients with anorexia nervosa.

Abstract
BACKGROUND & AIMS No study has yet compared body fat distribution before and after weight restoration in adolescent and adult patients with anorexia nervosa (AN) treated according to the same protocol. The study was set up to measure body fat distribution before and after short-term weight restoration in adolescent and adult patients with AN treated according to the same protocol in a specialist inpatient unit. METHODS We recruited 33 consecutive adolescent female patients with AN, and 33 controls matched by age and post-treatment BMI centile, as well as 33 adult female patients with AN, and 33 controls matched by age and post-treatment BMI. Dual-energy X-ray absorptiometry (DXA) was used to assess body composition before and after short-term weight restoration (BMI ≥ 18.5 kg/m²). RESULTS Compared with controls, both adolescents and adults with AN showed that a greater amount of fat was lost from the extremities than the trunk before weight restoration, and that there was a central adiposity phenotype after short-term weight restoration. There were no significant differences in body fat distribution between adolescents and adults with AN before or after short-term weight restoration. CONCLUSIONS Adolescent and adult females with AN have similar body fat distribution both before and after short-term weight restoration, and show a central adiposity phenotype after short-term weight restoration. The clinical implications of this finding are as yet unknown. Clinical Trials Registry- Regional Fat Distribution in Adolescent Girls and Adults with Anorexia Nervosa (ISRCTN73572502).
