Purpose:
RAS mutations represent common driver alterations in thyroid cancer. They can be found in benign, low-risk and malignant thyroid tumors with follicular architecture, which are often diagnosed as indeterminate nodules on preoperative cytology. Therefore, the detection of RAS mutations in preoperative setting has a suboptimal predictive val...
Purpose
An increase in serum TSH concentrations in the absence of thyroid disease, named isolated hyperthyrotropinemia, is frequently observed in subjects with obesity. It is directly associated with body mass index, and it is reversible following weight loss. Autoimmune hypothyroidism is frequently associated with obesity, it is usually progressiv...
Objective
Obesity is a recognized risk factor for the progression to severe forms of COVID-19, yet the mechanisms of the association are unclear.
Methods
Subcutaneous abdominal adipose tissue specimens of subjects deceased from COVID-19 ( n = 23) were compared to those of controls dying abruptly from causes other than infectious (accidental trauma...
PurposeSubjects with obesity may exhibit an increase in serum TSH concentrations. Several mechanisms have been proposed to explain this association, including the presence of a compensatory mechanism to counterbalance an accelerated turnover of thyroid hormones in subjects with obesity. This study aimed at evaluating whether the thyroids of subject...
Purpose
Glucagon-like peptide 1 (GLP-1) is an incretin hormone that appears to play a major role in the control of food intake. The aim of this investigation was to evaluate and quantify the association of circulating GLP-1 concentration with ad libitum total calorie and macronutrient intake.
Methods
One-hundred and fifteen individuals (72 men) ag...
Context
Skeletal muscle endocannabinoids and sphingolipids (particularly, sphingomyelins) are inversely associated with sleeping energy expenditure (SLEEP) in humans. The endocannabinoid system may increase sphingolipid synthesis via cannabinoid receptor-1.
Objective
To investigate in human skeletal muscle whether endocannabinoids are responsible...
Aims:
Exenatide is a glucagon-like peptide 1 (GLP-1) mimetic which induces weight loss predominantly, it is presumed, via decreased food intake. However, circulating GLP-1 is also a determinant of energy expenditure. We sought to quantify the effect of exenatide on energy expenditure (EE) and energy intake.
Materials and methods:
In this single-...
Background/objectives:
Energy expenditure (EE), as reflective of body energy demand, has been proposed to be the key driver of food intake, possibly influencing weight change in humans. Variation in this energy-sensing link (overeating relative to weight-maintaining energy requirements) may lead to weight gain over time.
Subjects/methods:
Sixty-...
Context
The endocannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG), and the related acylethanolamide oleoylethanolamide (OEA) have been implicated in energy expenditure (EE)-regulation and metabolic diseases. Muscle (fat-free mass, FFM) and fat (fat mass, FM) are metabolically active compartments and main determinants of EE.
Objective...
The pathogenesis of human obesity is the result of dysregulation of the reciprocal relationship between food intake and energy expenditure (EE), which influences daily energy balance and ultimately leads to weight gain. According to principles of energy homeostasis, a relatively lower EE in a setting of energy balance may lead to weight gain; howev...
Background/Objectives
In animal models, a role in the regulation of energy expenditure (EE) has been ascribed to sphingolipids, active components of cell membranes participating in cellular signaling. In humans, it is unknown whether sphingolipids play a role in the modulation of EE and, consequently, influence weight gain. The present study invest...
Background:
Obesity and hypothyroidism are both common disorders within the general population. Obese hypothyroid subjects require higher doses of L-T4 as compared to normal weight individuals. Previous studies on the effects of bariatric surgery on L-T4 dose requirements in hypothyroid subjects provided conflicting results. The aim of this study...
A reciprocal interaction between the hypothalamo-pituitary-thyroid axis and the adipose tissue is required for the proper homeostasis of energy balance. In this chapter, the mechanisms by which the two systems regulate each other and the effects of thyroid dysfunctions on body weight will be discussed.
In both lean and obese subjects, thyroid hormo...
Objective
Progressive lipodystrophy is one of the major features of the rare MDPL syndrome. Until now, 9 patients affected by this syndrome have been described and a recent study identified in 4 of them an in-frame deletion (Ser605del) of a single codon in the POLD1 gene. Sequence alterations of the POLD1 gene at different sites have been previousl...
