Randomized Controlled Trial
Smartphone technology facilitates dietary change in healthy adults.
Many individuals are advised to adhere to specific diet plans for their personal health; hence, it is important that tools are available to support these behaviors. Smartphone applications (apps) may assist health care professionals in educating their clients on specific dietary modifications. This pilot study focused on a single dietary modification, reducing sodium intake, to determine whether a commercial health app is useful for promoting dietary change. ⋯ These data suggest that smartphone apps have the potential to facilitate the implementation of dietary advice. This was a small pilot study with limited scope, and more research is necessary to determine the value of smartphone apps for facilitating dietary change.

The aim of this study was to assess the association between protein and arginine from meat intake and oxidative stress in a general population. ⋯ High protein and arginine from meat intake were associated with oxidative stress independently of genetic, lifestyle, and biochemical confounders in a population-based study. Our results suggested a novel link between high protein/arginine intake and oxidative stress, which is a major cause of age-related diseases.

The aim of this study was to evaluate the effects of the classic ketogenic diet (KD) on low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subfractions in children and adolescents with refractory epilepsy. ⋯ KD treatment promotes negative changes in lipoprotein size and phenotype, contributing to atherogenic risk in these patients.

Brain-derived neurotrophic factor (BDNF) is associated with the risk for Alzheimer's disease and type 2 diabetes. The aim of this study was to examine the association of BDNF variants with type 2 diabetes and the interactions of different BDNF genotypes with dietary habits and food and nutrient intakes in middle-aged adults. ⋯ BDNF Val/Met and Met/Met variants (rs6265) decreases the risk for glucose intolerance and type 2 diabetes. BDNF variants interacted with nutrient intake, especially energy and protein intake: Middle-aged individuals with BDNF Val/Val are prone to developing type 2 diabetes even with low energy and protein intake.

Case Reports
Hyperglycemia and subsequent torsades de pointes with marked QT prolongation during refeeding.
A fatal cardiac complication can occasionally present in malnourished patients during refeeding; this is known as refeeding syndrome. However, to our knowledge, hyperglycemia preceding torsades de pointes with QT prolongation during refeeding has not been reported. In the present study, we present a case in which hyperglycemia preceded torsades de pointes with QT prolongation during refeeding. The aim of this study was to determine the possible mechanism underlying QT prolongation during refeeding and indicate how to prevent it. ⋯ Hyperglycemia during refeeding can present with QT prolongation; consequently, monitoring blood glucose levels may be useful in avoiding hyperglycemia, which can result in QT prolongation. Furthermore, additional monitoring of QT intervals using a 12-lead electrocardiogram should allow the early detection of QT prolongation when glucose solution is administered to a malnourished patient with (severe) hypoglycemia.
