Objective: to develop and internally validate a nomogram to predict recurrence-free survival (RFS) including the time to radical cystectomy (RC) and perioperative blood transfusion (PBt) as potential ***: Patients who underwent open RC and ileal conduit between January 1996 to December 2016 were split into developing (n=948) and validating (n=237) cohorts. the time to radical cystectomy (ttC) was defined as the interval between the onset of symptoms and RC. the regression coefficients of the independent predictors obtained by Cox regression were used to construct the nomogram. Discrimination, validation, and clinical usefulness in the validation cohort were assessed by the area under the curve, the calibration plot, and decision curve ***: In the developing dataset, the 1-, 5-, and 10-year RFS were 83.0%, 47.2%, and 44.4%, respectively. On multivariate analysis, independent predictors were ttC (hazards ratio [hR] 1.07, 95% confidence interval [CI] 1.05-1.08, pt (one unit: hR 1.40, 95% CI 1.03-1.90, p=0.03;two or more units: hR 1.72, 95% CI 1.29-2.29, pteral hydronephrosis (hR 1.54, 95% CI 1.21-1.97, phR 0.60, 95% CI 0.45-0.81, p=0.001), pt3-t4 (hR 1.77, 95% CI 1.41-2.22, ph node status (hR 1.53, 95% CI 1.21-1.95, phovascular invasion (hR 1.28, 95% CI 1.01-1.62, p=0.044). the areas under the curve in the validation dataset were 79.3%, 69.6%, and 76.2%, for 1-, 5-, and 10-year RFS, respectively. Calibration plots showed considerable correspondence between predicted and actual survival probabilities. the decision curve analysis revealed a better net benefit of the ***: A nomogram with good discrimination, validation, and clinical utility was constructed utilizing ttC and PBt in addition to standard pathological criteria.

Investigation of hCAR2 antagonists as a potential strategy to modulate bovine leukocytes

Background Dairy cows experiencing ketosis after calving suffer greater disease incidence and are at greater risk of leaving the herd. In vitro administration of beta-hydroxybutyric acid(BhBA;the primary blood ketone) has inhibitory effects on the function of bovine leukocytes. BhBA is a ligand of hCAR2 and the activation of these receptors promotes an anti-inflammatory response which may be related with immunosuppression observed in transition dairy cattle. the objective of this study was to identify and test antagonists for hCAR2 in bovine immune cells cultured with *** We observed expression of hCAR2 at the protein level within lymphocytes, monocytes, and granulocytes. the proportion of cells expressing hCAR2 tended to be greater in mid-lactation compared to early lactation cows;the increase was a result of increased proportion of t and B cells expressing hCAR2. Stimulation of hCAR2 with niacin or BhBA promoted Ca^(2+) mobilization in neutrophils and mononuclear cells. Mononuclear cells treated with BhBA had diminished intracellular Ca^(2+) responses when hCAR2 was knocked down by si RNA silencing, indicating Ca^(2+) mobilization was mediated by hCAR2 signaling. two candidate antagonists for hCAR2, synthesized from niacin(NA-1 and NA-5), were tested;monocytes and neutrophils pre-treated with NA-1 and NA-5 had reduced Ca^(2+) mobilization after incubation with BhBA. Furthermore, NA-5 but not NA-1 prevented BhBA-associated reductions in cyclic *** We demonstrated that hCAR2 is present on bovine leukocytes and has greater expression later in lactation. We confirmed that BhBA and niacin derived hCAR2 antagonists alter bovine leukocyte activity. Our results demonstrate that both BhBA and niacin affect bovine leukocyte Ca^(2+) mobilization in a hCAR2-dependent manner.
