BACKGROUND AND OBJECTIVES By studying cardiometabolic risk factors in children born after maternal biliopancreatic diversion bariatric surgery (AMS) compared with those in children born before maternal surgery (BMS), we tested the hypothesis that significant maternal weight loss may modify obesity-related factors transmitted via the intrauterine(More)
BACKGROUND Few genes have been associated with the metabolic syndrome (MS), although its genetic component is well accepted. The aim of this study was to compare the adipose tissue gene expression profiles of obese men with and without the MS and to apply an integrative genomic approach to propose new candidate genes. METHODS Affymetrix HG-U133 plus 2(More)
BACKGROUND In the past 10 years, most bariatric surgeries have seen an important reduction in the early complication rate, partly associated with the development of the laparoscopic approach. Our objective was to assess the current early complication rate associated with biliopancreatic diversion with duodenal switch (BPD-DS) since the introduction of a(More)
BACKGROUND Biliopancreatic diversion (BPD) is a complex bariatric operation requiring meticulous surveillance which has impeded its broad adoption. Improvements in surgical care and technique, better teaching programs, and stringent norms for follow-up have contributed to increased safety of BPD for patients with BMI <50, achieving better long-term results(More)
Epigenetic mechanisms may be involved in the regulation of genes found to be differentially expressed in the visceral adipose tissue (VAT) of severely obese subjects with (MetS+) versus without (MetS-) metabolic syndrome (MetS). Long interspersed nuclear element 1 (LINE-1) elements DNA methylation levels (%meth) in blood, a marker of global DNA methylation,(More)
Obesity is associated with an increased risk of Type 2 diabetes and cardiovascular diseases (CVD). The severely obese population is heterogeneous regarding CVD risk profile. Our objective was to identify metabolic pathways potentially associated with development of metabolic syndrome (MetS) through an analysis of overrepresented pathways from differentially(More)
BACKGROUND Comparative evaluation of weight loss after bariatric surgery is difficult without definition of success and without a norm for presenting results. We explored the pertinence of defining success: a residual BMI <40 or <35 kg/m(2), and the need for reporting results with stratification by initial obesity and length of follow-up. METHODS Results(More)
The aim of the present study was to investigate pathways of progesterone metabolism in human adipose cells. Adipose tissue samples from the omental (OM) and subcutaneous (SC) fat compartments were surgically obtained in women. In isolated mature adipocytes, progesterone was converted to 20alpha-hydroxyprogesterone as the main metabolite, most likely through(More)
The prevalence of morbid obesity and its associated metabolic complications has risen rapidly in the past decade. Recently, we have established the transcriptome of the visceral adipose tissue of nondiabetic severely obese men with and without metabolic syndrome (MetS) that provided new candidate genes for cardiovascular disease (CVD) risk factors. The(More)
BACKGROUND This report summarizes our 15-year experience with duodenal switch (DS) as a primary procedure on 1,423 patients from 1992 to 2005. METHODS Within the last 2 years, follow-up of these patients, including clinical biochemistry evaluation by us or by their local physician is 97%. RESULTS Survival rate was 92% after DS. The risk of death (Excess(More)
