Short and middle term effects of hypocaloric low carbohydrate diet vs hypocaloric Mediterranean diet on endothelial function in obese subjects
2008
Adequate nutritional treatment is required to address the problem of increasing prevalence of obesity in Western countries. The Mediterranean diet style is now acknowledged to have large scientific evidences in terms of cardiovascular prevention. However, many popular diets are diffusing also as self-prescribed treatments. Among those, the efficacy of low-carbohydrate diets (also known as Atkins’ diet in its most popular variety) has been addressed by some investigations. It is generally concluded that the low-carbohydrate diet is able to induce a greater weight loss, at least in the middle term, and a better serum lipid profile than the conventional diet. In this longitudinal, randomised, …
The magnesium global network (MaGNet) to promote research on magnesium in diseases focusing on covid-19
2021
When the current SARS-CoV-2 pandemic began in early 2020, the global magnesium researcher community came together and noted the striking similarities between COVID-19 risk factors and conditions associated with magnesium deficit state in humans, reasoning that magnesium deficiency could worsen the course of COVID-19 [1-4]. This prompted establishment of a worldwide collaborative network with regular virtual meetings to brainstorm the associations between magnesium and COVID-19. We hypothesize that magnesium deficiency, a common but mostly unrecognized state in modern global societies, could be an important component of the susceptibility to SARS-CoV-2 infection. Consequently, restoring the …
CB(1) signaling in forebrain and sympathetic neurons is a key determinant of endocannabinoid actions on energy balance
2010
The endocannabinoid system (ECS) plays a critical role in obesity development. The pharmacological blockade of cannabinoid receptor type 1 (CB(1)) has been shown to reduce body weight and to alleviate obesity-related metabolic disorders. An unsolved question is at which anatomical level CB(1) modulates energy balance and the mechanisms involved in its action. Here, we demonstrate that CB(1) receptors expressed in forebrain and sympathetic neurons play a key role in the pathophysiological development of diet-induced obesity. Conditional mutant mice lacking CB(1) expression in neurons known to control energy balance, but not in nonneuronal peripheral organs, displayed a lean phenotype and res…

Tomografía computarizada a nivel de C3 y dinamometría como técnicas de diagnóstico de sarcopenia en pacientes con cáncer de cabeza y cuello
2020
Introducción: Estudio piloto que determina el diagnóstico de sarcopenia mediante tomografía computarizada (TC) a nivel de la tercera vértebra cervical (C3) y dinamometría en pacientes con cáncer de cabeza y cuello. Comparación de la masa magra (MM) determinada mediante TC con técnicas clásicas de antropometría y dinamometría.Material y métodos: Se analizó la MM y el tejido adiposo mediante TC a nivel de C3 en 37 pacientes oncológicos mediante Unidades Hounsfield (UH). Posteriormente, se calculó el índice musculoesquelético (IME) y se determinó la fuerza prensora de mano para la determinación de sarcopenia. Por último, se comparó el IME mediante técnicas de valoración antropométrica clásica …
PAP/HIP protein is an obesogenic factor
2013
In this article we report the obesogenic role of the acute phase protein PAP/HIP. We found that the transgenic TgPAP/HIP mice develop spontaneous obesity under standard nutritional conditions, with high levels of glucose, leptin, and LDL and low levels of triglycerides and HDL in blood. Accordingly, PAP/HIP-deficient mice are skinny under standard nutritional conditions. We also found that expression of PAP/HIP is induced in intestinal epithelial cells in response to gavage with olive oil and this induction is AG490 sensitive. We demonstrated that incubation of 3T3-L1 preadipocytes with a low concentration as 1ng/ml of recombinant PAP/HIP results in accelerated BrdU incorporation in vitro. …
Alternative options for prescribing physical activity among obese children and adolescents: brisk walking supported by an exergaming platform
2015
[EN] Background: Physical inactivity has been identified as an important public health concern for children. An increasing sedentary way of life is directly related to obesity; hence, prevention and management of childhood obesity are commonly based on lifestyle interventions wherein increasing physical activity is one of the main targets. The use of exergames can be useful in promoting physical activity, but it is necessary more research. This study analyzes the effects of an exergaming platform that involves brisk walking, on perceived exertion, self-efficacy, positive expectations and satisfaction in a sample of clinically obese children, as compared with normal weight children. Physiolo…
Reply to "The association of red blood cell distribution width and morbid obesity" by Aydin et al.
2014
We thank Aydin & cols. for their comments about our recently published paper “Red blood cell distribution width is not related with inflammatory parameters in morbidly obese patients” in Clinical Biochemistry Journal [1]. The authors show their concern about the clinical interpretation of our findings since we did not report folate and B12 vitamin levels. Moreover, they state that we should demonstrate the elimination of thrombocytopenic diseases by showing platelet count data. Aswe state in the paper, exclusion criteria for obese patients included “organic, malignant, hematological, infectious or inflammatory disease”. Therefore, any case of thrombocytopenic disease was not included. Moreo…
Weight loss is associated with improvements in cognitive function among overweight and obese people: A systematic review and meta-analysis
2017
Whilst obesity is associated with a higher risk of cognitive impairment, the influence of weight loss on cognitive function in obese/overweight people is equivocal. We conducted a meta-analysis of randomized controlled trials (RCTs) and longitudinal studies evaluating the influence of voluntary weight loss on cognitive function in obese/overweight individuals. Articles were acquired from a systematic search of major databases from inception till 01/2016. A random effect meta-analysis of weight loss interventions (diet, physical activity, bariatric surgery) on different cognitive domains (memory, attention, executive functions, language and motor speed) was conducted. Twenty studies (13 long…
Obesity and Interpersonal Problems: An Analysis with the Interpersonal Circumplex
2012
This study examines the interpersonal problems profiles of obese individuals by cluster analysing the interpersonal problems circumplex scores of participants. The Inventory of Interpersonal Problems— Short Circumplex (IIP‐32) was completed by 368 treatment‐seeking obese individuals. These data were cluster analysed, and groups of obese subjects defined by varying interpersonal problems were compared with regard to psychological distress, self‐esteem, body dissatisfaction, quality of life and binge behaviours. Cluster analyses of the IIP‐32 resulted in four clusters, which occupied two quadrants of the interpersonal circumplex. Several differences in body mass index, psychological distress,…
