Objectives To evaluate whether there is an association between the serum levels of the novel insulin-like adipokine isthmin-1 (ISM1) and obesity-related phenotypes in a population of Spanish children and to investigate the plausible molecular alterations behind the alteration of the serum levels of this protein in children with obesity. Methods Th...

Exclusive breastfeeding is recommended for the first six months of life to promote adequate infant growth and development, and to reduce infant morbidity and mortality. However, whenever some mothers are not able to breastfeed their infants, infant formulas mimicking human milk are needed, and the safety and efficacy of each formula should be teste...
Preprint
Background Puberty is a time of considerable metabolic and hormonal changes associated with a physiological increase in peripheral tissue insulin resistance (IR). There is evidence that physiological IR does not resolve in youth who are obese, which may result in increased cardio-metabolic risk. Understanding the molecular and biological processes...

Introduction Metabolic syndrome (MetS) is a cluster of clinical and metabolic alterations related to the risk of cardiovascular diseases (CVD). Metabolic changes occurring during puberty, especially in children with overweight and obesity, can influence the risk of developing chronic diseases, especially CVD. Methods Longitudinal study based on th...

Full-text available
Introduction The main cause of insulin resistance in childhood is obesity, which contributes to future comorbidities as in adults. Although high-calorie diets and lack of exercise contribute to metabolic disease development, food quality rather than the quantity of macronutrients is more important than food density. The purpose of the present study...

Pre-clinical studies suggest that circulating oxylipins, i.e., the oxidation products of polyunsaturated fatty acids (PUFAs), modulate gut microbiota composition in mice, but there is no information available in humans. Therefore, this study aimed to investigate the relationship between omega-3 and omega-6 derived oxylipins plasma levels and fecal...

Vitamin D (VD) is a fat-soluble vitamin, and pivotal for maintaining health. Several genetic markers have been related to a deficient VD status; these markers could confer an increased risk to develop osteoporosis and other chronic diseases. A VD deficiency could also be a determinant of a severe COVID-19 disease. This study aimed to interrogate ge...

Puberty has been described as a life stage of considerable metabolic risk specially for those with obesity. The low-grade systemic inflammatory status associated with obesity could be one of the connections with metabolic syndrome (MetS). Thus, we aimed to assess the relationship between inflammatory and cardiovascular biomarkers and the developmen...
Chapter
A variety of mediators participate in the resolution of the inflammatory process, among which are lipoxins, resolvins, protectins and maresins. These mediators mitigate the infiltration of polymorphonuclear leukocytes, decrease the production of pro-inflammatory compounds and stimulate the uptake of apoptotic polymorphonuclear-dependent macrophages...
Article
Background: the evaluation of diet quality (DQ) is fundamental to the study of disease-diet associations, and an easy-to-apply tool in nursing homes (NHs) is necessary. Our objective was to propose a novel diet quality indicator (DQIn) using an a priori approach for NHs. Methods: the QUality Index for Nutrition in Nursing homes (QUINN) was imple...
Chapter
Intercellular communication is mainly carried out by hormones, neurotransmitters, eicosanoids, growth factors and cytokines. Eicosanoids are chemical mediators with high biological activity, derived from fatty acids of 20 carbon atoms. Among them, prostaglandins, prostacyclins, thromboxanes and leukotrienes stand out. Eicosanoids are involved in th...

Exercise modulates both brown adipose tissue (BAT) metabolism and white adipose tissue (WAT) browning in murine models. Whether this is true in humans, however, has remained unknown. An unblinded randomized controlled trial (ClinicalTrials.gov ID: NCT02365129) was therefore conducted to study the effects of a 24-week supervised exercise interventio...

Background Enoyl-CoA hydratase short-chain 1 (ECHS1) is a key mitochondrial enzyme that is involved in valine catabolism and fatty acid beta-oxidation. Mutations in the ECHS1 gene lead to enzymatic deficiency, resulting in the accumulation of certain intermediates from the valine catabolism pathway. This disrupts the pyruvate dehydrogenase complex...

Background: Breastmilk is the ideal food for infants and exclusive breastfeeding is recommended. In the clinical trial aimed to evaluate a new starting formula on weight gain of infants up to 6 and 12 months. The novel formula was compared with a standard formula and breastfeeding, the latter being used as the reference method. Methods: 210 infants...
Article
Objectives Brown adipose tissue (BAT) is important in the maintenance of cardiometabolic health in rodents. Recent reports appear to suggest the same in humans, although if this is true remains elusive partly because of the methodological bias that affected previous research. This cross-sectional work reports the relationships of cold-induced BAT v...
