BACKGROUND Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservati...

BACKGROUND Pressures from the "obesogenic" environment are driving up obesity rates, but adiposity still varies widely within the population. Appetitive characteristics could underlie differences in susceptibility to the environment. OBJECTIVE We examined associations between adiposity and 2 appetitive traits: satiety responsiveness and food cue responsiveness in children. DESIGN Parents of...

In this paper, we generalize a result by Berman and Billig on weight modules over Lie algebras with polynomial multiplication. More precisely, we show that a highest weight module with an exp-polynomial “highest weight” has finite dimensional weight spaces. We also get a class of irreducible weight modules with finite dimensional weight spaces over generalized Virasoro algebras which do not occ...

BACKGROUND About 90% of type 2 diabetic patients are obese or overweight. The obvious clinical improvement observed with surgeries, such as Roux-en-Y gastric bypass, has opened space for research by different factors than only weight loss, as responsible for the return to euglycemia and reduction of medication use. AIM To evaluate the efficacy and safety of surgical treatment of diabetes in o...

INTRODUCTION The influence of adolescent obesity on weight loss following bariatric surgery in adults has not been evaluated. The purpose of this study was to determine the impact of prior adolescent obesity on long-term weight changes following Roux-en-Y gastric bypass (RYGB) in adulthood. MATERIAL AND METHODS This single centre retrospective cohort study evaluated changes in body mass index...

The sign-rank of a matrix A with entries in {−1,+1} is the least rank of a real matrix B with Aij · Bij > 0 for all i, j. Razborov and Sherstov (2008) gave the first exponential lower bounds on the sign-rank of a function in AC, answering an old question of Babai, Frankl, and Simon (1986). Specifically, they exhibited a matrix A = [F (x, y)]x,y for a specific function F : {−1, 1} × {−1, 1} → {−...

background: metabolically obese normal-weight (monw) children and adolescents are characterized by body mass index (bmi) lower than +1sd with metabolic disorders such as hyperglycemia, hypertriglyceridemia, and/or hypertension. this study wants to determine prevalence of monw, metabolically benign normal weight (mbnw), metabolically abnormality obese (mao) and compare the components of metaboli...

Brain natriuretic peptide (BNP) is the most effective predictor of outcomes in chronic heart failure (CHF). This study sought to determine the qualitative relationship between the BNP levels at discharge and on the day of cardiovascular events in CHF patients. We devised a mathematical probabilistic model between the BNP levels at discharge (y) and on the day (t) of cardiovascular events after ...

Given k > 2, we show that there are at most finitely many rational numbers x and y 6= 0 and integers ` > 2 (with (k, `) 6= (2, 2)) for which x(x+ 1) · · · (x+ k − 1) = y. In particular, if we assume that ` is prime, then all such triples (x, y, `) satisfy either y = 0 or ` < exp(3k).

Background: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in women of reproductive age, affecting 7% of this population. Although not entirely understood, the etiology of PCOS is closely linked to obesity and abdominal adiposity that are considered to worsen the clinical presentation, particularly menstrual irregularities and hyperandrogenism. Lifestyle mo...
