BACKGROUND Leptin, body weight, body mass index (BMI) and other hormones in women with functional hypothalamic amenorrhoea (FHA) were investigated and the hypothesis proposed that energy imbalance is the predominant mechanism for leptin reduction in patients with FHA. METHODS Eighty-eight women with FHA and 65 age- and weight-matched controls were divided into homogeneous groups on the basis ...

Background. Efforts are needed to improve the long-term efficiency of childhood obesity treatment. To adapt strategies, the identification of subgroups of patients with a greater weight loss may be useful. Objective. To analyze the results of a chronic care program for childhood obesity and to determine baseline factors (medical, dietary, and psychosocial) associated with successful weight loss...

BACKGROUND Roux-en-Y gastric bypass (RYGBP) is presently one of the most popular surgical procedures for obesity. One of the possible long-term problems is weight regain, usually after a period of successful weight loss. Weight regain after RYGBP can be due to new eating habits, like sweet-eating or grazing, or volume eating because of impaired restriction. This paper reports our experience in ...

INTRODUCTION The prevalence of overweight and obesity in children is rapidly increasing in many countries. For that it has been interesting to investigate the eating habits of 8-9 y-old Tuscany children by paying attention to their meals frequency per day and their food choices in total and in relation to children's Body Mass Index (BMI) classes. In addition we considered some environment facto...

OBJECTIVE The present study describes the consumption patterns of sweetened food and drink products in a Catholic Middle Eastern Canadian community and examines its associations with physical activity, sedentary behaviours and BMI. DESIGN A two-stage cross-sectional design was used. In Stage 1 (n 42), 24 h recalls enabled the identification of sweetened products. In Stage 2 (n 192), an FFQ wa...

BACKGROUND Currently, there is no consensus opinion regarding the optimal procedure of choice in super-super-morbid obesity (Body mass index, BMI > 60 kg/m²). Roux-en-Y gastric bypass (RYGB) is associated with failure to achieve or maintain 50% excess weight loss (EWL) or BMI < 35 in approximately 15% of patients. Also, percent EWL is significantly less after 1-year in the super-super-obese gro...

OBJECTIVES The pathogenesis of anorexia nervosa (AN) remains still unclear. It has been reported that neuropeptides may play a role in the control of appetite and hormone release contributing to hormonal disturbances in AN. However the question if neuropeptide alterations are consequence or cause of malnutrition is still unresolved. METHODS Serum leptin, neuropeptide Y (NPY) concentrations as...

Introducing the notation Xt := exp(itP),Ys := exp(isQ),Zr := exp(ir)I we can bring this into the form XtYs = ZstYsXt . Furthermore, we have the one-parameter group property Xt1+t2 = Xt1Xt2 (and similarly for Y and Z) and that Z commutes with X and Y . We observe that these relations still make sense when the parameters are elements of an arbitrary commutative ring. †currently visiting the Dept....
