Osteocalcin carboxylation is not associated with body weight or percent fat changes during weight loss in post-menopausal women.
Osteocalcin (OC) is a vitamin K-dependent bone protein used as a marker of bone formation. Mouse models have demonstrated a role for the uncarboxylated form of OC (ucOC) in energy metabolism, including energy expenditure and adiposity, but human data are equivocal. The purpose of this study was to determine the associations between changes in measures of OC and changes in body weight and percent body fat in obese, but otherwise healthy post-menopausal women undergoing a 20-week weight loss program. All participants received supplemental vitamins K and D and calcium. Body weight and body fat percentage (%BF) were assessed before and after the intervention. Serum OC [(total (tOC), ucOC, percent uncarboxylated (%ucOC)], and procollagen type 1N-terminal propeptide (P1NP; a measure of bone formation) were measured. Women lost an average of 10.9 ± 3.9 kg and 4 %BF. Serum concentrations of tOC, ucOC, %ucOC, and P1NP did not significantly change over the twenty-week intervention, nor were these measures associated with changes in weight (all p > 0.27) or %BF (all p > 0.54). Our data do not support an association between any serum measure of OC and weight or %BF loss in post-menopausal women supplemented with nutrients implicated in bone health.

A Multi-institutional Study on the Mid-Term Outcomes of Single Anastomosis Duodeno-Ileal Bypass as a Surgical Revision Option After Sleeve Gastrectomy.
Recently, a single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) has become increasingly popular for patients with BMI > 50 as a primary or staged surgery. Staging allows surgeons to do the sleeve gastrectomy (SG) first with the conversion only happening when a failure or technical challenge is identified.. We present the mid-term outcomes of SADI bypass surgery after SG.. A retrospective analysis was performed on a prospective database from four institutions. Ninety-six patients were identified from 2013 to 2018. Patients were divided into two groups: one had two-stage SADI because of insufficient weight loss, the second had planned two-stage SADI because of super obesity (BMI > 50 kg/m. Of 96 patients, 3 patients were completely lost to follow-up. The mean age was 44.8 ± 11.3 years. There were no deaths or conversion to open surgery. The postoperative early complication and late complication rate was 5.3% and 6.4% respectively. At 24 months, group 2 had higher %weight loss (WL) and change in BMI units compared to group 1 with statistically significant difference. The average WL and change in BMI for entire patient's population at 24 months after 2nd stage SADI was 20.5% and 9.4 units respectively. The remission rate for DM was 93.7% with or without the use of medication.. The two-stage approach to SADI-S appears technically simpler than a single compromised operation. However, this approach needs more patients to understand its limitations.
