may explain differences in net intestinal oxalate absorption in humans. There is also a potential link to the fecal microbiome, which has organisms that may promote deglycosylation. This may prove to be a significant translational research platform. Dean G. Assimos, MD

Abstract available at http://www.ncbi.nlm.nih.gov/pubmed/27673722 Editorial Comment: This group previously reported on the shared medical appointments for stone prevention and found that patients were satisfied with this approach. In this study they analyzed changes in 24-hour urinary stone risk parameters in those who had individualized appointments and those who participated in shared visits. Improvements were seen in both groups, and patient satisfaction was for the most part similar. Shared appointments have been used for other urological disease processes and are an efficient way of providing access to care. Differences in stone recurrence between these 2 approaches need to be assessed. Dean G. Assimos, MD

Abstract available at http://www.ncbi.nlm.nih.gov/pubmed/27663026 Editorial Comment: Oxalobacter formigenes is an anaerobic bacterium whose main carbon source is oxalate. Lack of fecal colonization with this organism is a risk factor for recurrent calcium oxalate stone formation. The authors studied the biology of O. formigenes in germ-free and altered Schaedler flora (ASF) mice. They demonstrated that this organism effectively degrades oxalate in the intestine and ASF bacteria do not. They also showed that ASF bacteria may bolster the integrity of the intestinal epithelium and perhaps limit paracellular oxalate transport. They also found that O. formigenes may survive in an aerobic environment. This is an excellent model to study the biological impact of this organism. Dean G. Assimos, MD
