“Background. Reduced testicular volume (TV) (<12 cm(3)) is associated with lower testicular function. Several studies explored the conventional sperm parameters
(concentration, motility, and morphology) and the endocrine function (gonadotropins and testosterone serum concentrations) in the patients with reduction of TV. No other parameters have been examined. Aim. This study aims at evaluating some biofunctional sperm parameters by flow cytometry in the semen of men with reduced TV compared with that of subjects with normal TV. Methods. 78 patients without
primary scrotal disease were submitted to ultrasound evaluation of the testis. They were divided into two groups according to testicular volume: A Group, including 40 patients with normal testicular volume (TV > 15 cm(3)) and B Group, including 38 patients with reduced testicular PFTα mw volume (TV <= 12 cm(3)). All patients underwent serum hormone concentration, conventional and biofunctional (flow cytometry) sperm parameters evaluation. Results. With regard to biofunctional sperm parameters, all values (mitochondrial membrane potential, phosphatidylserine externalization, chromatin compactness, and DNA fragmentation) were strongly negatively correlated with testicular volume (P < 0.0001). Conclusions. This study for the first time in the literature states that the biofunctional sperm parameters worsen and with near linear correlation, with decreasing testicular volume.”
“Background: For intramucosal undifferentiated early gastric cancer (EGC), gastrectomy with lymphadenectomy
is now the standard therapy. However, because approximately 96% of intramucosal undifferentiated EGC do not have BB-94 price lymph node metastasis (LNM). Gastrectomy with lymphadenectomy may be overtreatment for such patients. This study was conducted to identify clinicopathological factors predictive of LNM in undifferentiated EGC and further to expand the possibility of using endoscopic mucosal resection (EMR) for the treatment of undifferentiated EGC.
Methods: Data from 108 patients with undifferentiated EGC and surgically treated were collected, and the association between the clinicopathological factors and the presence of LNM were retrospectively analyzed by univariate and multivariate logistic regression analyses. Odds ratios (ORs) with 95% confidence interval (95% CI) were calculated.
Results: The tumor size (OR = 11.475, 95% CI: 2.054-64.104, P = 0.005), depth of invasion (OR = 11.704, 95% CI: 2.536-54.010, P = 0.002), and lymphatic vessel involvement (LVI) (OR = 13.688, 95% CI: 1.779-105.324, P = 0.
