Randomized Controlled Trial
Macronutrient composition and its effect on body composition changes during weight loss therapy in patients with non-alcoholic fatty liver disease: Secondary analysis of a randomized controlled trial.
Dietary composition may affect body composition during weight loss therapy. We tested the hypothesis of whether dietary macronutrient composition influences the reduction of total abdominal adipose tissue, subcutaneous adipose tissue (SAT), or visceral adipose tissue (VAT) during weight loss. ⋯ The 5:2 and LCHF diets had similar effects on changes in intraabdominal fat mass and anthropometrics during weight loss. This might indicate that overall weight loss is more important than diet composition to achieve changes in total abdominal adipose tissue, VAT, or SAT. The results of the present study suggest that there is a need for further studies on the effect of diet composition on body composition changes during weight loss therapy.

This study aimed to evaluate the association of vitamin D with sleep quality during the COVID-19 pandemic and the influence of daily sunlight on this association. ⋯ Vitamin D deficiency was associated with poor sleep quality in individuals with insufficient exposure to sunlight.

Carnitine is essential for transporting long-chain fatty acids into mitochondria and promotes energy metabolism via β-oxidation of long-chain fatty acids. Although carnitine is also present in the peripheral blood, 98% of total carnitine is stored in muscle tissue. Neuromuscular diseases accompanied by muscle atrophy are likely to lead to secondary carnitine deficiency, owing to the reduced amount of total carnitine stored in the body. ⋯ Neuromuscular diseases accompanied by muscle atrophy may lead to acute carnitine deficiency, even if the serum carnitine concentration is within the normal range before onset. During sick days, it may be necessary to modify a patient's treatment, such as increasing both oral supplementation and intravenous administration of carnitine.

The aim of this study was to compare safety and efficacy of long-term home parenteral nutrition between patients with systemic sclerosis and intestinal failure (IF) and controls with IF from another etiology. ⋯ Long-term HPN in SSc-related IF is feasible but unveils occult cardiac disease.

Assessing food intake of pregnant women is extremely important, because maternal dietary patterns can influence fetal development as well as have either positive or negative effects on both the mother and fetus. Thus, the aim of the present study was to carry out a systematic review of the literature on food frequency questionnaires developed and validated for pregnant women, in order to assess their methodological quality and validation process. ⋯ Food frequency questionnaires developed for pregnant women appear to be reliable tools to assess food intake by this group. Overall, they had good methodological quality and adequate correlation coefficients compared with reference methods.
