ry therapy can improve prognosis. Nevertheless, longer-term studies with larger population of patients are needed to verify their biological behavior and therapeutic efficacy.
Choriocarcinoma is exceedingly rare disease with metastases at initial diagnose and has poor survival even after treatment. Old age and advanced tumor stage indicate a poor prognosis, while surgery therapy can improve prognosis. Nevertheless, longer-term studies with larger population of patients are needed to verify their biological behavior and therapeutic efficacy.
Conventional cryopreservation methods induce chemical and mechanical damage to the sperm membranes. The cryoprotectant potential of phospholipids of vegetal origin as soybean lecithin has been investigated as a substitute for egg yolk in diluents used for the cryopreservation of human spermatozoa. Therefore, the objective of this study was comparing the efficacy of a synthetic cryoprotectant supplemented with L-α-phosphatidylcholine (PC) and L-acetyl-carnitine (ANTIOX-PC) and the standard egg-based TEST-yolk buffer (TYB) in preserving sperm motility and chromatin quality in cryopreserved semen samples.
Prospective experimental study in which semen samples from 63 men with normal sperm motility and 58 men with low sperm motility were included and analyzed both before and after cryopreservation using ANTIOX-PC or TYB freezing media. Onalespib datasheet Sperm quality was evaluated by routine semen analysis and DNA fragmentation index using the Terminal deoxynucleotidyl transferase dUTP nick end labeling assay.
Differences in cycle compared to the TYB medium. A clinically relevant advantage in better preserving kinetic parameters as higher total motility and lower immotile post-thawed sperm from ANTIOX-PC, in normal and low motility semen samples, demonstrated the positive impact of phospholipid and antioxidant treatment on sperm cryotolerance with high potential for egg yolk lipids replacement and biosafety.
To investigate the association between lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and metabolic syndrome (MetS) in aging Chinese males.
A dataset that included 3,568 non-MetS cases and 1,020 MetS cases (after data cleansing) was downloaded from the China Health and Retirement Longitudinal Study (CHARLS). To balance the intergroup covariates, propensity score matching (PSM) was employed in the analyses. Univariate logistic regression and multivariate logistic regression were then performed to investigate the relationship between LUTS/BPH and MetS in aging Chinese males.
Before PSM, multivariate logistic regression showed that participants with MetS had a 1.47 times higher risk of LUTS/BPH compared to non-MetS cases in the final model (P<0.001). It also revealed that participants with low high-density lipoprotein (HDL), abdominal adiposity, or high triglycerides had a higher probability of LUTS/BPH [odds ratio (OR) =1.56 for low HDL; OR =1.50 for abdominal adiposied risk of LUTS/BPH; however, this was not the case for hypertensive patients.
Smoking status has been confirmed as an independent prognostic factor for bladder cancer. However, for patients who received neoadjuvant chemotherapy (NAC), the influence of smoking status on the pathological response and prognosis remains unclear. This pooled analysis aimed to investigate whether smoking status is an independent risk factor for pathological response, recurrence, and prognosis in patients with bladder cancer who undergo NAC.
We searched PubMed, Web of Science, Embase, Cochrane Library, and Google Scholar for related studies published between 1990 and 2017. In total, 10 studies comprising 1,382 patients with muscle-invasive bladder cancer were included. The odds ratio (OR) and 95% confidence interval (CI) of complete pathological response, partial pathological response, overall survive (OS), recurrence, and cancer-specific mortality (CSM) were chosen as outcome measures. Analyses were performed using Review Manager (version 5.3, The Cochrane Collaboration, UK) and Stata statistical software (version 15, Stata Corp., USA).
Compared to nonsmokers, smokers were less likely to have a complete pathologic response (OR =0.55, 95% CI 0.35-0.87) and partial pathological response (OR =0.57, 95% CI 0.37-0.88). However, we found no significant association between smoking status and overall survival (OR =0.71, 95% CI 0.28-1.80), recurrence (OR =1.35, 95% CI 0.97-1.88), and cancer-specific mortality (OR =0.90, 95% CI 0.62-1.32).
Smoking reduces both complete and partial pathological response rate to NAC in patients with bladder cancer. Thus, smoking status should be given more importance when developing treatment plans and evaluating efficacy, particularly of NAC, among bladder cancer patients.

The benefit of adjuvant chemotherapy remains controversial in muscle-invasive bladder cancer (MIBC) after radical cystectomy. The present study’s primary objective was to construct a predictive tool for the reasonable application of adjuvant chemotherapy.
All of the patients analyzed in the present study were recruited from the Surveillance Epidemiology and End Results program between 2004 and 2015. Propensity score matching (PSM) was used to reduce inherent selection bias. Cox proportional hazards models were applied to identify the independent prognostic factors of overall survival (OS) and cancer-specific survival (CSS), which were further used to construct prognostic nomogram and risk stratification systems to predict survival outcomes. The prognostic nomogram’s performance was assessed by concordance index (C-index), receiver-operating characteristic (ROC) and calibration curves. Decision curve analysis (DCA) was performed to evaluate the clinical net benefit of the prognostic nomogram.
A total of found to be beneficial for high-risk patients, while low-risk patients should be carefully monitored.
We have constructed a predictive model and different risk stratifications for selecting a population that could benefit from postoperative adjuvant chemotherapy. Adjuvant chemotherapy was found to be beneficial for high-risk patients, while low-risk patients should be carefully monitored.
