The post-RYGB pregnant women showed an elevated serum inadequacy (deficiency or insufficiency) of 25(OH)D during pregnancy. Maternal vitamin D status showed no association with maternal variables, except UTI, and the neonatal variables analyzed.

The objective of this study was to describe the main factors related to the installation and/or aggravation of vitamin D deficiency (VDD) and its clinical consequences in pregnant women after bariatric surgery. An electronic search on VDD in pregnancy and after bariatric surgery was conducted in publications from 1998 until 2012 that presented studies performed in humans. We provided an overview of VDD after bariatric surgery, in pregnancy, and in pregnancy in women who underwent bariatric surgery. In view of the high percentage of VDD postoperatively and the role of this vitamin in pregnancy, we recommend the investigation of vitamin D nutritional status in prenatal care.

Background: The transradial approach is currently the first option for percutaneous coronary procedures, whether diagnostic or therapeutic, particularly in patients with acute coronary syndromes. However, there is limited data in the literature comparing the use of a universal catheter from a radial approach versus the transfemoral approach. The purpose of this study was to demonstrate the feasibility of the single-catheter radial approach compared with the transfemoral approach. Methods: A retrospective assessment of cases of acute coronary syndrome undergoing invasive risk stratification and ad hoc percutaneous coronary intervention by transradial or transfemoral approach. In the transradial group, we selected cases in which one single guiding catheter was used in the procedure. Results: Between November 2011 and January 2013, we investigated 198 patients who met the selection criteria. Except for the higher mean age observed in the transradial group (63.5 vs. 59.2; p=0.002), there were no differences in clinical characteristics. In addition, there were no differences in clinical presentation, culprit vessel, number and size of the stents used, or final angiographic success rate. The number of vascular complications was higher, particularly hematomas <5cm, in the transfemoral group. Conclusion: The use of single-catheter transradial approach is feasible, safe and effective in managing patients with acute coronary syndrome.
