Background: In low-birth-weight girls, obesity increases the risk of premature adrenarche and metabolic complications. However, the consistency of this association in normal-birth-weight children and its potential mediators remain unknown. Objectives: The objectives were to assess the associations between obesity indicators and dehydroepiandrosterone sulfate (DHEAS) at 7 y of age and to evaluat...

(L1) ∣∣∣∣ ẏ = by, y(0) = x0, ẋ = ax, x(0) = y(t), (L2) ∣∣∣∣ ẏ = ay, y(0) = x0, ẋ = bx, x(0) = y(t). Pour le système (L1), on a clairement x(t) = exp(at)x(0) = exp(at)y(t) = exp(at) exp(bt)y(0) = exp(at) exp(bt)x. Le calcul pour (L2) se fait de la même manière et donne le même résultat. On appelle splitting de Lie les deux méthodes (L1) et (L2). Pour une équation scalaire, ces deux méthodes sont...

Background: Infertility problem affects young couples. One of the known causes of spermatogenic disorder is chemotherapy in patients with cancer. Since dividing cells are mainly affected by anticancer drugs, the aim of the present study is to investigate the preventive effect of GnRH on spermatogenic defect produced by anticancer drug. Materials and Methods: In the present study 30 adult female...

BACKGROUND It is not clear whether and how rapid growth in infancy, a risk factor for later obesity, differentially affects growth and body-composition development throughout childhood in term children with an appropriate-for-gestational age (AGA) birth weight. OBJECTIVE The aim was to examine the effect of rapid growth in infancy on body mass index SD score (BMI SDS) and body fat percentage ...

Background: Prevalence of obesity in the world, in both developed and developing countries, is growing rapidly. Bariatric surgery is now accepted as the treatment for morbid obesity. Objective: This study compares laparoscopic sleeve gastrectomy's effectiveness (LSG) with the most common bariatric surgery, laparoscopic Roux-en-Y (LRYGB) gastric bypass.   Methods: A systematic review ...

The individual response to diet may be influenced by gene polymorphisms. This study hypothesized that ADRB2 (Gln27Glu, rs1042714 and Arg16Gly, rs1042713), ADRB3 (Trp64Arg, rs4994) and GHRL (Leu72Met, rs696217) polymorphisms moderate weight loss. The study was a seven weeks dietary weight loss intervention with Brazilian adult obese women (n = 109). The body mass index (BMI) was calculated and p...

OBJECTIVE To evaluate the early effect of Roux-en-Y (RYGB) gastric bypass on hormones involved in body weight regulation and glucose metabolism. SIGNIFICANT BACKGROUND DATA: The RYGB is an effective bariatric procedure for which the mechanism of action has not been elucidated yet. Reports of hormonal changes after RYGB suggest a possible endocrine effect of the operation; however, it is unknown...

BACKGROUND Guidelines for optimal weight in older persons are limited by uncertainty about the ideal body mass index (BMI) or the usefulness of alternative anthropometric measures. OBJECTIVE We investigated the association of BMI (in kg/m(2)), waist circumference, and waist-hip ratio (WHR) with mortality and cause-specific mortality. DESIGN Subjects aged >/=75 y (n = 14 833) from 53 family ...

HYPOTHESIS Systolic and diastolic pressure and the incidence of hypertension in very obese patients decline after bariatric surgery and do not rebound. DESIGN Chart review. SETTING Surgical practice in a university medical center. PATIENTS Women and men, 18 years or older, with a body mass index (BMI) (calculated as weight in kilograms divided by the square of height in meters) of 40 or g...
