Evaluation of body composition is a relevant clinical instrument for the follow-up assessments of children and adolescents, and dual-energy X-ray absorptiometry (DXA) is an accurate method for the pediatric population. However, DXA has limited scan area for the obese population. Thus, half-body scans emerged as an alternative to evaluate individuals with obesity. The aim of this study was to compare the body composition of children and adolescents with whole- and half-body DXA scans, considering nutritional status, pubertal development, sex, and age. ⋯ The use of half-body scans was feasible and accurate to evaluate whole-body composition. The difference bias between techniques occurred randomly and was clinically irrelevant. A high correlation was observed between half- and whole-body analysis techniques.

Medical nutrition therapy (MNT), by lifelong compliance with a gluten-free diet, is likely the only treatment for celiac disease (CD). Clinical practice guidelines (CPGs) regarding the management of CD emphasize the role of MNT over other treatment options. The aim of the present study was to review and critically appraise CD-specific MNT CPGs and identify areas in need of improvement for better adherence and outcomes. ⋯ The present study reveals the low quality of guidelines regarding the MNT of CD patients, indicating the need for updated and improved guidelines taking into consideration the proposed items of AGREE II.

Dietary habits are fundamental issues to assess when modulating health and well-being; however, different nutritional panels may help individuals prevent acute and chronic pain. Many substances, known to be active antioxidants and anti-inflammatory compounds, should serve this fundamental task. ⋯ Furthermore, correct intake of trace elements and minerals is strategic to reduce inflammation-related pain. This review addresses these items in an effort to suggest new criteria for proper dietary supplementation to prevent pain.

Obesity, weight loss, and its influence on telomere length: New insights for personalized nutrition.
Telomeres are structures located at the ends of chromosomes associated with proteins, from the shelterin complex, which are responsible for the protection and preservation of the genetic material. The telomere length (TL) progressively decreases with each cell division, and recent evidence suggests that lifestyle can lead to telomere shortening. ⋯ Thus, the aim of the present review was to show the relationship between obesity and TL in addition to the possible risk factors for its shortening and how the different strategies for weight loss can modulate TL. As the crucial result, we can consider the association between TL and weight loss, and adiposity changes after different interventions, showing that TL may be used as a biomarker of responses to obesity treatment.

Observational Study
Association between preoperative nutritional status and postoperative delirium in individuals with coronary artery bypass graft surgery: A prospective cohort study.
The prevalence of delirium and undernutrition are both relatively high subsequent to coronary artery bypass graft (CABG) surgery. The aim of this study was to evaluate the association between preoperative malnutrition and the occurrence of delirium after CABG surgery. ⋯ Since the prevalence of delirium is relatively high in CABG surgery and undernutrition is related to postoperative delirium, considering nutrition status with NRS-2002, SGA, or adductor pollicis muscle thickness before surgery could decrease the risk for postoperative delirium.
