Randomized Controlled Trial
Effect of magnesium supplementation on depression status in depressed patients with magnesium deficiency: A randomized, double-blind, placebo-controlled trial.
The aim of this study was to determine the effect of magnesium supplementation on the depression status of depressed patients suffering from magnesium deficiency. ⋯ Daily consumption of 500 mg magnesium oxide tablets for ≥8 wk by depressed patients suffering from magnesium deficiency leads to improvements in depression status and magnesium levels. Therefore, assessment of the magnesium serum and resolving this deficiency positively influence the treatment of depressed patients.

The aim of this review was to convey updated information on the role of microRNAs in adipogenesis, chronic low-grade inflammation, and insulin resistance in obesity. Obesity is a chronic disease characterized by the presence of metabolic disorders (e.g., low-grade chronic inflammation), which contributes to the manifestation of insulin resistance. Diverse molecular mechanisms have been implicated in the development of these disorders, and microRNAs stand out as a contributing factor. ⋯ It is important to point out that obese individuals show alterations in the expression of microRNAs favoring manifestation of the metabolic disorders present in these patients, and these alterations may be reversed by the loss of weight. Therefore, microRNAs may be regarded as potential biomarkers of obesity-related disorders. Further studies on this topic may advance the understanding of the molecular basis of obesity, including the participation of microRNAs in the pathogenesis of this disease.

Multicenter Study
Nutritional support practices in hematopoietic stem cell transplantation centers: A nationwide comparison.
In 2009, international nutritional societies published practice guidelines on screening and nutritional support for patients undergoing stem cell transplantation. Little is known about how these guidelines are implemented in clinical practice. We performed a nationwide survey with the aim of understanding current practice patterns, differences between clinical practice, and international recommendations as well as barriers to the use of nutritional therapy. ⋯ This Swiss survey found wide variation in the use of nutritional therapy in patients undergoing stem cell transplantation, with low adherence overall to current practice guidelines. Understanding and reducing barriers to guideline implementation in clinical practice may improve clinical outcomes. Close collaboration of centers will facilitate future research needed to improve current practice and ensure high quality of treatment.

In patients with cancer, weight loss can be related to simple starvation, disturbed metabolism, or both. In patients with head and neck cancer (HNC), weight loss often is attributed to simple starvation because the obvious oral symptoms are known to hinder dietary intake. In this population, cachexia remains a relatively unexplored phenomenon. The aim of this study was to explore the prevalence of cachexia and precachexia in patients with newly diagnosed HNC. ⋯ This exploratory study suggested a high prevalence of cachexia (42%) in patients with newly diagnosed HNC. Although a large study is needed to further elucidate the role of cachexia in patients with HNC, the data presented here suggest that cachexia is a common problem in this patient population, which has therapeutic and prognostic implications.

Periodic fasting, under a religious aspect, has been adopted by humans for centuries as a crucial pathway of spiritual purification. Caloric restriction, with or without exclusion of certain types of food, is often a key component. Fasting varies significantly among different populations according to cultural habits and local climate conditions. ⋯ The long-term significance of such changes on global health remains to be explored. This review summarizes the data available with regard to benefits of fasting followed for religious reasons on human health, body anthropometry, and cardio-metabolic risk markers; aims to bridge the current knowledge gap on available evidence and suggests considerations for the future research agenda. Future studies should explore every type of religious fasting, as well as their consequences in subpopulations such as children, pregnant women, and the elderly, or patients with chronic metabolic diseases.
