“Objectives: NSC-23766 To determine more conclusively whether intravenous (IV) administration of 3% saline is more efficacious than oral administration in reversing below normal

blood sodium concentrations in runners with biochemical hyponatremia. Design: Randomized controlled trial. Methods: 26 hyponatremic race finishers participating in the 161-km Western States Endurance Run were randomized to receive either an oral (n=11) or IV (n = 15) 100 mL bolus of 3% saline. Blood sodium concentration (Na+), plasma protein (to assess %plasma volume change), arginine vasopressin (AVP), blood urea nitrogen (BUN) and urine (Na+) were measured before and 60 min following the 3% saline intervention. Results: No significant differences were noted with respect to pre- to post-intervention blood [Na+] change between intervention groups, although blood [Na+] increased over time in both intervention groups (+2 mmol/L; p smaller than 0.0001). Subjects receiving

the IV bolus had a greater mean (+/- SD) plasma volume increase (+8.6 +/- 4.5% versus 1.4% +/- 5.7%; p smaller than 0.01) without significant change in [AVP] (-0.2 +/- 2.6 versus 0.0 +/- 0.5 SCH727965 clinical trial pg/mL; p = 0.49). 69% of subjects completing the intervention trial were able to produce urine at race finish with a mean (+/- SD) pre-intervention urine [Na+] of 15.2 +/- 8.5 mmol/L (range 0-35; NS between groups). [BUN] of the entire cohort pre-intervention was 30.7 +/- 10.5 mg/dL (range 13-50). Conclusions: No group difference was noted in the primary outcome measure of change in blood [Na+] over 60 min of observation following a 100 mL bolus of either oral or IV 3% saline.

“To examine

the relationship between cytotoxic T lymphocyte antigen 4 (CTLA-4) expression and breast cancer prognosis, CTLA-4 expression was immunohistochemically detected in paraffin-embedded specimens of primary tumors from 130 patients with breast cancer who had a mean follow-up period of 112 months. CTLA-4 expressed in cytoplasm of breast cancer cells and in cytoplasm and cell membranes of interstitial lymphocytes. Univariate analysis (log-rank) associated higher density of interstitial CTLA-4(+) lymphocytes with longer DFS and OS, but higher tumor CTLA-4 expression with shorter OS. After controlling for age, clinical stage, Scarff-Bloom-Richardson grade, tumor thrombus, ER, PR, HER2 and Ki-67, multivariate analysis (Cox) showed that density of interstitial CTLA-4(+) lymphocytes independently predicted longer DFS (HR 0.315, P = 0.002) and OS (HR 0.313, P = 0.
