Obesity is a rapidly emerging health problem and an established risk factor for cardiovascular diseases. Bariatric surgery profoundly reduces body weight and mitigates sequelae of obesity. The open, randomized controlled WAS trial compares the effects of Roux-en-Y gastric bypass (RYGB) versus psychotherapy-supported lifestyle modification in morbidly obese patients. The co-primary endpoint addresses 1-year changes in cardiovascular function (peak VO2 during cardiopulmonary exercise testing) and quality of life (Short-Form-36 physical functioning scale). Prior to randomization, all included patients underwent a multimodal anti-obesity treatment for 6-12 months. Thereafter, patients were randomized and followed through month 12 to collect primary endpoints. Afterwards, patients in the lifestyle group could opt for surgery, and final visit was scheduled for all patients 24 months after randomization. Sample size calculation suggested to enroll 90 patients in order to arrive at minimally 22 patients per group evaluable for the primary endpoint. Secondary objectives were to quantify changes in body weight, left ventricular hypertrophy, systolic and diastolic function (by echocardiography and cardiac magnet resonance imaging [MRI]), functional brain MRI, psychometric scales, endothelial and metabolic function. WAS enrolled 93 patients (72 women, median age 38 years, BMI 47.5 kg/m2) exhibiting a relevantly compromised exercise capacity (median peakVO2 18.3 ml/min/kg) and quality of life (median physical functioning scale 50). WAS is the first randomized controlled trial focusing on the effects of RYGB on cardiovascular function beyond hypertension. In addition, it will provide a wealth of high-quality data on cerebral, psychiatric, hepatic, and metabolic function in obese patients after RYGB. The trial is registered at (NCT01352403).

Background: Fibroblast growth factor-23 (FGF23) is a key regulator of urine phosphate excretion. The aim of the study was to investigate the perioperative (intraoperative and postoperative) changes of plasma intact and C-terminal FGF23 (iFGF23, cFGF23) concentrations in patients with primary hyperparathyroidism (pHPT) submitted to surgery.

Materials and methods: Study involved 38 adult patients with pHPT caused by adenoma. PTH levels were investigated intraoperatively (just before the incision and 10 minutes after adenoma excision). cFGF23, iFGF23, phosphate, eGFR and P1NP were measured intraoperatively and postoperatively (next day after the surgery).

Results: PTH levels decreased intraoperatively (13.10 vs. 4.17 pmol/L, P<0.0001). FGF23 levels measured intraoperatively were at the upper level of reference interval. cFGF23 decreased postoperatively compared with values measured just before the incision (cFGF23: 89.17 vs. 22.23 RU/mL, P<0.0001). iFGF23 decreased as well, but postoperative values were low. Postoperative inorganic phosphate values increased (1.03 mmol/L vs. 0.8 mmol/L, P=0.0025). We proved significant negative correlation of perioperative FGF23 with inorganic phosphate (cFGF23: Spearman r=-0.253,P=0.0065; iFGF23: Spearman r =-0.245, P=0.0085). We also found FGF23 values just before incision correlated with eGFR (cystatin C) (cFGF23: Spearman r=-0.499, P=0.0014; iFGF23: Spearman r=-0.413, P=0.01).

Conclusion: Intraoperative iFGF23 and cFGF23 did not change despite PTH decreased significantly. cFGF23 and iFGF23 significantly decreased one day after parathyroidectomy and are associated with increase of inorganic phosphate in pHPT patients. cFGF23 and iFGF23 just before incision correlated with eGFR (cystatin C). The similar results found in both iFGF23 and cFGF23 suggest each could substitute the other.

Introduction The early concept of surgical intervention to mediate weight loss in patients suffering from obesity stemmed from the observation of the substantial and often problematic weight loss following gastrointestinal surgery for cancer
