  • 简介:我们与高风险的前列腺癌症在271个病人报导全面的率,地点和积极外科的边缘(PSM)的预兆的因素。在2008年4月和2011年10月之间,我们有希望地从作为D'Amico分类的病人收集了数据高风险经历了帮助机器人的laparoscopic激进分子前列腺切除术。PSM的全面的率和地点被报导。逐步的逻辑回归模型被适合估计PSM的预兆的因素。PSM的全面的率是25.1%(271个病人中的68个)。这些PSM,(68中的26个)38.2%是posterolateral(PL),26.5%(68中的18个)multifocal,16.2%(68中的11个)在顶,14.7%(68中的10个)在膀胱颈,并且4.4%(3/68)在另外的地点。有病理学的阶段pT2的病人的PSM率是8.6%(140中的12个),26.6%(64中的17个)pT3a,53.3%(32/60)pT4的pT3b,和100%(7中的7个)。在包括pre-,intra-,和手术后的参数的一个逻辑回归模型,身体团索引(机会比率[或]:1.09;95%信心间隔[CI]:1.01-1.19,P=0.029),病理学的舞台(pT3b或更高对pT2;或:5.14;95%CI:1.92-13.78;P=0.001)并且肿瘤的百分比(或:46.71;95%CI:6.37-342.57;P<0.001)是为PSM的独立预兆的因素。在病人在的PSM的最普通的地点高风险是PL方面,它反映报导肿瘤攻击性。PSM的唯一的重要预兆的因素是病理学的结果,例如在标本和病理学的舞台的肿瘤的百分比。

  • 简介:AbstractBackground:Resting heart rate (RHR) is considered as a strong predictor of total mortality and hospitalization due to heart failure in hypertension patients. Bisoprolol fumarate, a second-generation beta-adrenoreceptor blockers (β-blocker) is commonly prescribed drug to manage hypertension. The present study was to retrospectively evaluate changes in the average RHR and its association with cardiovascular outcomes in bisoprolol-treated coronary artery disease (CAD) patients from the CAD treated with bisoprolol (BISO-CAD) study who had comorbid hypertension.Methods:We performed ad-hoc analysis for hypertension sub-group of the BISO-CAD study (n = 866), which was a phase IV, multination, multi-center, single-arm, observational study carried out from October 2011 to July 2015 across China, South Korea, and Vietnam. Multivariate regression analysis was used to identify factors associated with incidence of composite cardiac clinical outcome (CCCO), the results were presented as adjusted odds ratio (OR) along with 95% confidence interval (CI) and adjusted P value.Results:A total of 681 patients (mean age: 64.77 ± 10.33 years) with hypertension from BISO-CAD study were included in the analysis. Bisoprolol improved CCCOs in CAD patients with comorbid hypertension, with RHR <65 and <70 beats/min compared with RHR ≥65 and ≥75 beats/min, respectively, in the efficacy analysis (EA) set. In addition, it lowered RHR in both intent-to-treat (ITT) and EA groups after 6, 12, and 18 months of treatment. Further, RHR 70 to 74 beats/min resulted in significantly higher risk of CCCOs EA set of patients (adjusted OR: 4.34; 95% CI: 1.19-15.89; P = 0.03). Also, events of hospitalization due to acute coronary syndrome were higher when RHR 69 to 74 beats/min compared to RHR <69 beats/min in ITT patients.Conclusion:Bisoprolol can effectively reduce RHR in Asian CAD patients with comorbid hypertension and hence, improve CCCO without affecting their blood pressure.

  • 简介:AbstractBackground:One inevitable shortcoming of non-invasive prenatal screening (NIPS)/cell-free DNA (cfDNA) sequencing is the uninterpretable ( "no-call" ) result, which is mainly caused by an insufficient fetal fraction. This study was performed to investigate the factors associated with a successful second NIPS in these cases and determine the optimal management for women with initial no-call results.Methods:We retrospectively analyzed the data of women who underwent NIPS with initial no-call results due to an insufficient fetal fraction from 2017 to 2019 in our center. We compared these women’s maternal and pregnancy information with the data of women who had attained a successful second NIPS result and women who had received no-call results for a second time.Results:Among the 33,684 women who underwent NIPS, 137 with a no-call result underwent a retest. Comparison between the 87 (63.50%) women with a successful retest and the other 50 (36.50%) women showed a significant difference in both the initial fetal fraction and maternal body mass index (BMI), whereas the other factors showed no significant differences. In addition, with an initial fetal fraction of < 2.00%, the retest success rate was very limited.Conclusions:We identified two major factors associated with a successful NIPS retest: the initial fetal fraction and the maternal BMI. These findings suggest the need for specialized management for this subset of women and would be instructional for the counseling for these women.
