Comparisons of SiO Maser and Long-Period Variable Positions in the Aquarii and Omicron Ceti Binary Systems

We have determined that the absolute position of the centroid of SiO maser-emitting spots toward both R A~r ~nd o Cet are coincident with the position of the long-period variables (LPVs) in these binary systems to within the errors of measurement. The SiO positions were determined with the Hat Creek interferometer while the LPV positions were determined with the 8 inch (20 em) transit circle of the US Naval Observatory: These results contradict an earlier report of a circumbinary SiO maser far removed from the LPV in the R Aqr binary system, and we suggest statistical reasons for the discrepancy. We present high-resolution spectra of both sources and discuss possible models

Simultaneous liver-pancreas transplantation for cystic fibrosis-related liver disease: A multicenter experience

Background: Diabetes is associated with increased morbidity and mortality in patients with cystic fibrosis (CF). While liver transplantation is well established for CF-related liver disease (CFLD), the role of simultaneous liver pancreas transplantation is less understood. Methods: We polled 81 pediatric transplantation centers to identify and characterize subjects who had undergone simultaneous liver pancreas transplantation and obtain opinions about this procedure in CFLD. Results: Fifty (61.7%) polled transplant centers responded and 94% reported that they would consider simultaneous liver pancreas transplantation for CFLD and diabetes. A total of 8 patients with simultaneous liver pancreas transplantation were identified with median follow up of 38 months. All patients had pre-existing diabetes. Exocrine and endocrine pancreatic function was initially restored in all patients with later functional loss in one patient. Body mass index Z-score increased between one year pre-transplantation and one year post-transplantation (P = 0.029). Conclusions: Patients with CFLD undergoing initial assessment for liver transplantation may benefit from consideration of simultaneous liver pancreas transplantation.
