Limited value of angiogenic factors in obese women.

We performed a case-control study assessing the predictive value of sVEGFR and PlGF for preeclampsia in a population with high obesity prevalence. Body mass index and circulating mean concentrations of sVEGFR and PlGF were significantly higher in preeclamptic women. However, a two variable model associating sVEGFR and PlGF dosages was not better than the model including only age and BMI. When the prevalence of obesity is high, the extra benefit of the dosages of angiogenic factors appears to be of limited value.

[Gallbladder complications after bariatric surgery]. / Complications vésiculaires après chirurgie bariatrique.

With the increased incidence of obesity in the developed countries, and the failure of medical treatments, bariatric surgery has increased rapidly. Although laparoscopic gastroplasty is the most popular bariatric intervention in France, the gold standard tends to be the laparoscopic gastric bypass. The severe weight loss caused by this type of procedure induces specific middle or long term complications such as biliary lithiasis. In this literature we describe different physiopathological mechanisms of lithiasis after gastric bypass by coeliosurgery or gastroplasty, their diagnosis, and preventive treatment to avoid these complications.
