An experimental study on long term outcomes after magnetic esophageal compression anastomosis in piglets

2021

Abstract Background/Purpose Previous studies have shown that a patent, watertight esophageal anastomosis can be accomplished safely using specially-shaped magnets in piglets. However, it is unclear whether such a magnetic esophageal compression anastomosis (MECA) remains patent in the long-term. The purpose of this study was to evaluate the long-term outcome of MECA in an experimental pig model over an observation period of 2 months. Methods Ten piglets underwent creation of an MECA with custom-made 8 mm magnets and a U-shaped esophageal bypass loop to allow peroral nutrition at eight weeks of life. Two weeks later, the bypass loop was closed surgically, requiring the pigs to swallow via th…

Endothelial dysfunction in morbid obesity.

2013

Morbid obesity is a chronic multifunctional disease characterized by an accumulation of fat. Epidemiological studies have shown that obesity is associated with cardiovascular and metabolic disorders. Endothelial dysfunction, as defined by an imbalance between relaxing and contractile endothelial factors, plays a central role in the pathogenesis of these cardiometabolic diseases. Diminished bioavailability of nitric oxide (NO) contributes to endothelial dysfunction and impairs endothelium- dependent vasodilatation. But this is not the only mechanism that drives to endothelial dysfunction. Obesity has been associated with a chronic inflammatory process, atherosclerosis, and oxidative stress. …

The role of physical activity and exercise in obesity and weight management: Time for critical appraisal

2016

The prevalence of overweight and obesity has increased dramatically during last 3 decades with devastating consequences to public health. Recommended strategies to reduce obesity have focused on healthier diet and physical activity (PA). Clearly, these approaches have not been successful, but whether this is due to failure to restrict energy intake or to maintain high levels of energy expenditure has been the subject of great controversy. Consequently, there has been a great deal of confusion about the role of PA and exercise in obesity and weight management. In this article, the theoretical basis for considering reduced PA and energy expenditure as the cause of obesity is appraised. Furthe…

Ingesta nutricional en pacientes afectados de esclerosis lateral amiotrófica una consulta ambulatoria de nutrición artificial en Portugal

2021

Introducción: La Esclerosis Lateral Amiotrófica (ELA) es una patología neurodegenerativa crónica y progresiva, que produce la muerte de las motoneuronas. Deriva en pérdida de peso, de masa muscular e incremento de deficiencias nutricionales. Existe relación entre la ingesta nutricional y la patogénesis de la ELA. El objetivo de este análisis fue describir las características sociodemográficas, antropométricas y clínicas junto con la ingesta nutricional en una muestra de pacientes portugueses afectados de ELA. Material y Métodos: Se realizó una anamnesis clínica breve. El peso corporal fue evaluado siguiendo el protocolo de la International Society for the Advancement of Kinanthropometry (IS…

Type 2 diabetes mellitus and osteoarthritis

2019

Objectives: Type 2 diabetes mellitus (T2DM) and osteoarthritis (OA) are common diseases that frequently co-exist, along with overweight/obesity. While the mechanical impact of excess body weight on joints may explain lower limb OA, we sought to explore whether T2DM is linked to OA outside of excess weight and whether T2DM may play a role in OA pathophysiology. The consequence of T2DM on OA outcomes is a question of research interest. Methods: We conducted a critical review of the literature to explore the association between T2DM and OA, whether any association is site-specific for OA, and whether the presence of T2DM impacts on OA outcomes. We also reviewed the literature to assess the saf…

Postnatal weight change is influenced by mother-newborn pair leptin levels

2000

We investigated serum leptin levels in 103 mother-newborn-pairs; Cord leptin was significantly higher than mother's leptin (5.7 ± 5.5 vs. 22.1 ± 19.9 ng/ml; p <0.001). Cord leptin was significantly higher in females than males (6.9 ± 6.3 vs. 3.9 ± 3.6 ng/ml respectively; p <0.001), and correlated with maternal leptin (r = 0.24; p = 0.001), gestational age (r = 0.54; p <0.001), and birth weight (r = 0.56; p <0.001). Neonatal leptin at the 4(th) day significantly correlated with percent weight loss in the first four days of life. These observations shed light on the origin of cord leptin and on the role of leptin in postnatal weight loss. (C) 2000 Elsevier Science Inc.

Effects of three different water temperatures on dehydration in competitive swimmers

2011

Summary Aims The purpose of this study was to evaluate the effects of three different water temperatures on physiological responses (dehydration, sweat rate, urine output, rectal temperature and plasma electrolytes) of competitive athletes during a “simulated” race of 5 km in an indoor swimming pool. Methods Nine male competitive master swimmers swam 5 km with the water at temperatures of 23, 27 and 32 C. Immediately before (Pre) and after (Post) each trial, samples of blood and urine were collected, body weight was recorded and rectal temperature was measured. The dehydration percentage and sweat rate were the highest at 32 C and the lowest at 23 C (23 C: −0.9 ± 0.5; 27 C: −1.3 ± 0.6; 32 C…

How important are satiation and satiety for weight regulation?

2013

Abstract: This chapter discusses how body weight is regulated in adult humans by a cybernetic-like process, whose main physiological response is the control of food intake, while energy expenditure modulation probably only passively participates in the adjustment of energy balance. The historical emergence and scientific definition of the two concepts ‘satiety’ and ‘satiation’ are recapitulated and their respective roles in body weight regulation are discussed. The original methodology developed to differentiate and separately quantify the roles of satiety and satiation in the quantitative control of food intake of healthy human subjects is described. Finally, the respective importance of s…
