Sodium-glucose co-transporters type 2 inhibitors (SLGT2i) are highly effective in controlling type 2 diabetes, but reported beneficial cardiovascular effects suggest broader actions on insulin resistance. Weight loss may be initially explained by glycosuria-induced net caloric output and secondary volumetric reduction, but its maintenance could be due to loss of visceral fat mass. Structured ultrasound (US) imaging of abdominal adipose tissue ("eco-obesity") is a recently described methodology used to measure 5 consecutive layers of abdominal fat, not assessable by DEXA or CT scan: superficial subcutaneous (SS), deep subcutaneous (DS), preperitoneal (PP), omental (Om) and right perirenal (RK).

Omental and perirenal fat depots are considered predictors of metabolic complications. Liraglutide is particularly effective in reducing weight in patients with insulin-resistance, but its direct impact on each abdominal fat layer is unknown.

Parenteral nutrition can be used to manage malnutrition, but there is no clear consensus as to the optimal protein dosage. The objective of this systematic literature review (SLR) was to identify studies on malnourished oncology patients receiving home parenteral nutrition (HPN) where protein or amino acid delivery was reported in g/kg bodyweight/day, and to compare outcomes between patients receiving low (< 1 g/kg bodyweight/day), standard (1-1.

The aim of this study was to validate the technique, give measures of and , , and (retroperitoneal) fat and correlate them with MS markers.
Methods: Sequential US measures of these five abdominal fat layers were done at 397 adults.
Background: The use of apps to tackle overweight and obesity by tracking physical and dietary patterns and providing recommendations and motivation strategies to achieve personalized goals has increased over recent years. However, evidence of the efficacy, effectiveness, and safety of these apps is severely lacking.
Objective: The aim of this study was to identify efficacy, safety, and effectiveness criteria used to assess weight control, overweight, and obesity management in mobile health (mHealth) interventions through a systematic review.
Background And Aims: The main objective of the PREDyCES study was twofold. First, to analyse the prevalence of hospital malnutrition in Spain, both at admission and at discharge, and second, to estimate the hospital costs associated with disease-related malnutrition.
Methods: The study was a nationwide, cross-sectional, observational, multicentre study in routine clinical practice, which assessed the prevalence of hospital malnutrition both at patient admission and discharge using NRS-2002.
It is well known that hospital malnutrition is a highly prevalent condition associated to increase morbidity and mortality as well as related healthcare costs. Although previous studies have already measured the prevalence and/or costs of hospital nutrition in our country, their local focus (at regional or even hospital level) make that the true prevalence and economic impact of hospital malnutrition for the National Health System remain unknown in Spain. The PREDyCES® (Prevalence of hospital malnutrition and associated costs in Spain) study was aimed to assess the prevalence of hospital malnutrition in Spain and to estimate related costs.

Design: An ecological study carried out on the basis of Food and Agriculture Organization food balance sheets for three geographical areas of Europe (Mediterranean, north and east) over two time periods: 1961-1963 and 1998-2000. The average availability of total energy, energy provided from macronutrients and food groups was calculated for each area and each period studied.
Al-Andalus society (711-1492) based its idea of health on the wisdom of Classical Greece, the Hippocratic-Galenic theories, as well as the Persian and Hindu cultures. The twelfth century in al-Andalus is considered to be the most prolific period for works of a scientific and technical nature. At the time, the main treatises on dietetics were written and this science reached its widest expression with such leading figures as Ibn Wāfīd, Avenzoar, Averroes and Maimonides, whose works revealed the first scientific knowledge on the nutritional processes of the human body.

Objective: To analyse the effect of weight loss on peripheral inflammatory markers and subcutaneous adipocytokine production.
Context: Administration of glucocorticoids increases serum leptin levels in lean and obese individuals. A morning meal produces an increase in insulin, a cortisol peak, and an increase in leptin; these changes do not occur during fasting.
Objective: The objective of this study was to investigate whether inhibiting endogenous cortisol secretion with metyrapone decreases 24-h serum leptin levels and to determine whether a meal-related midmorning surge in cortisol is a prerequisite for the meal-entrained nocturnal rise in leptin.
Background: Understanding the distribution of high-sensitivity C-reactive protein (CRP) and its relations with classic cardiovascular risk factors in specific populations is important for further diagnostic use.
Methods: We studied 1,157 adult subjects (652 women and 505 men) participating in the Health Study of Catalonia. CRP concentrations were measured with a high-sensitivity turbidimetric assay.
Aims: To evaluate the effect of a whole formula diet on nutritional and cognitive status in Alzheimer's disease patients.
Methods: Patients were randomly assigned to two interventions: a whole formula diet based on lyophilised foods (Treatment Group, n=24) or nutritional advice (Control Group, n=29). Energy intake, body weight, biochemistry, Mini Nutritional Assessment (MNA) and Pfeiffer's tests were determined at baseline and at 3 months of treatment.
Recent evidences from epidemiological and intervention trials suggest that a higher calcium intake is associated with a lower body weight and a reduction in total and central body fat. The potential role of calcium intake in the regulation of body adiposity has been explained by the intracellular calcium, which is able to promote adipocyte fat accumulation by exerting a coordinate regulation stimulating lipogenesis and suppressing lipolysis. Moreover, the intracellular calcium has been implicated on the etiopathogenesis of hypertension, insulin resistance and dyslipidemia, appearing as a potential common substrate in the metabolic syndrome.

Until a few years ago, there were only two medical schools in Spain with a compulsory course in nutrition as part of the syllabus.
Goal: An attempt will be made to assess the current status of the teaching of nutrition within the syllabuses for a degree in Medicine and Surgery at Spanish universities.
Background: We evaluated the prevalence of co-morbidities, in particular diabetes, in a diverse population of morbidly obese patients who underwent gastric bypass surgery at our institution in New York City.
Methods: A retrospective study of 300 patients who had bariatric surgery between January 2001 and April 2002 was conducted.
Results: 57% of the patients had at least one metabolic complication, 30% had diabetes, 38% hypertension and 35% dyslipidemia.
Background/aim: Our previous studies showed that administration of dexamethasone plus food increased serum leptin levels 100% more than dexamethasone alone. We hypothesized that this increase in leptin from the meal could result directly from the provision of fuel metabolites rather than from the meal-induced rise in insulin. In the current study, we tested the effect of an i.
