Timing, Patterns and Predictors of 90-Day Readmission Rate after Robotic Radical Cystectomy
Purpose: We examine the timing, patterns and predictors of 90-day readmission after robotic radical cystectomy. Materials and methods: From September 2009 to March 2017, 271 consecutive patients undergoing robotic radical cystectomy with intent to cure bladder cancer (intracorporeal diversion 253, 93%) were identified from our prospectively collated institutional database. Readmission was defined as any subsequent inpatient admission or unplanned visit occurring within 90 days from discharge after the index hospitalization. Multiple readmissions were defined as 2 or more readmissions within a 90-day period. Logistic regression analysis was used to identify independent factors related to single and multiple 90-day readmissions. Results: A total of 78 (28.8%) patients were readmitted at least once within 90 days after discharge, of whom 20 (25.6%) reported multiple readmissions. The cumulative duration of readmission was 6.2 (6.17) days with 6 (7.6%) patients having less than 24 hours readmission. Metabolic, infectious, genitourinary and gastrointestinal complications were identified as the primary cause of readmission in 39.5%, 23.5%, 22.3% and 17%, respectively. Fifty percent of readmissions occurred in the first 2 weeks after hospital discharge. On multivariable logistic regression analysis in-hospital infections (OR 2.85, p=0.001) were independent predictors for overall readmission. Male gender (OR 3.5, p=0.02) and in-hospital infections (OR 4.35, p=0.002) were independent predictors for multiple readmissions. Conclusions: The 90-day readmission rate following robotic radical cystectomy is significant. In-hospital infections and male gender were independent factors for readmission. Most readmissions occurred in the first 2 weeks following discharge, with metabolic derangements and infections being the most common causes

GPR40 partial agonists and AgoPAMs: Differentiating effects on glucose and hormonal secretions in the rodent
Structural basis for the cooperative allosteric activation of the free fatty acid receptor GPR40
Clinical studies indicate that partial agonists of the G-protein-coupled, free fatty acid receptor 1 GPR40 enhance glucose-dependent insulin secretion and represent a potential mechanism for the treatment of type 2 diabetes mellitus. Full allosteric agonists (AgoPAMs) of GPR40 bind to a site distinct from partial agonists and can provide additional efficacy. We report the 3.2-Ă… crystal structure of human GPR40 (hGPR40) in complex with both the partial agonist MK-8666 and an AgoPAM, which exposes a novel lipid-facing AgoPAM-binding pocket outside the transmembrane helical bundle. Comparison with an additional 2.2-Ă… structure of the hGPR40-MK-8666 binary complex reveals an induced-fit conformational coupling between the partial agonist and AgoPAM binding sites, involving rearrangements of the transmembrane helices 4 and 5 (TM4 and TM5) and transition of the intracellular loop 2 (ICL2) into a short helix. These conformational changes likely prime GPR40 to a more active-like state and explain the binding cooperativity between these ligands
