    Due to the scarcity of cases of testicular choriocarcinoma (CC), its clinicopathological characteristics and prognosis have not been well summarized. Consequently, we conducted this population-based case-control study to characterize the features of testicular CC.

    The SEER database was used to extract qualified data. Dichotomous variables were compared by Pearson’s Chi-squared or Fisher exact test. Survival variables were compared by Kaplan-Meier analyses and log-rank tests. The univariable and multivariable Cox regression analyses were applied to figure out risk factors for overall survival (OS) and cancer-specific survival (CSS). Propensity score matching (PSM) was used to control confounding factors in the study.

    In total, 788 patients with CC and 19,571 patients with seminoma were identified. Significant differences were found between two groups in terms of age (≤30 years 65.4%

    26.5%; >30 years 34.6%

    73.5%; P<0.001), marital status (28.8%

    52.1%; P<0.001), laterality (proportion of gnosis, 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.

    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. check details 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. link2 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.

    The purpose of this study is to explore the effects of high-BDNF microenvironment produced by engineered immortalized mesenchymal stem cells (imMSCs) on the neurogenic bladder (NB) and investigate underlying mechanism.

    Male Sprague-Dawley rat (12-week-old, weighing about 370-400 g) were purchased from a Korean company (Orient Bio Co. Seongnam, Korea) and divided into the following groups (n=32) sham control group (n=8), NB group (n=8), NB + ImMSCs group (n=8), NB + ImMSCs (BDNF) group (n=8). The major pelvic ganglion (MPG) was observed under anesthesia. Three NB groups of rats were then subjected to bilateral MPG injury. The sham control group of rats was treated with sham surgery. Cystometry were performed before the rats were sacrificed, and then MPG and bladder were collected for histochemical and Western blot analysis.

    MSCs treatment improves lower urinary tract function, and the NB + ImMSCs (BDNF) group is better than the NB + ImMSCs group (P<0.01). MSCs treatment accelerates recovery of injuredmechanism may be related to the activation of the BDNF/TrkB/CREB signaling pathway and the reduction of apoptosis by highly expressed BDNF.

    To evaluate the feasibility and effect of upper urinary tract videourodynamics in complex reconstructed upper urinary tract.

    From January 2016 to December 2018, patients who underwent complex upper urinary tract reconstruction and received upper urinary tract videourodynamics were included in the study. The modified Whitaker test was performed at 3 months after operation. The relative pelvic pressure was defined as the pelvic pressure minus the bladder pressure. Based on the flow rate, the test was divided into physiological phase and high flow phase. The results of pressure and image were classified into 3 types. Successful nephrostomy removal was defined as no symptoms and improved or stable hydronephrosis.

    A total of 12 patients who underwent complex upper urinary tract reconstruction received modified Whitaker test. All tests were successfully completed without adverse reactions. The relative pelvic pressure of 3 patients kept steady near the baseline throughout the examination and was classified ine removed safely.

    The modified Whitaker test is initially safe and feasible in postoperative evaluation of complex upper urinary tract reconstruction surgery. Detailed results can provide more evidence to judge whether nephrostomy tube could be removed safely.

    To date, few studies have evaluated the role of peripheral blood T lymphocyte subsets in patients with clear cell renal cell carcinoma (ccRCC). Here we measured the levels of peripheral blood T lymphocyte subsets and evaluated its prognostic value in ccRCC.

    Data from 122 patients with RCC from January 2018 to January 2020 were collected. Preoperative peripheral blood T lymphocyte subsets and medical records were analyzed. Kaplan-Meier cures and log rank test were used for analyzing overall survival (OS). Univariate and multivariate survival analyses were underwent by performing the Cox proportional hazards models. Correlations were tested by Pearson’s correlation analysis.

    Of 122 patients, a total of 80 ccRCC patients was enrolled. Patients with low CD3

    T cells and low CD4

    /CD8

    ratio displayed a worse OS than patients with high CD3

    T cells and high CD4

    /CD8

    ratio (P=0.029 and 0.002, respectively). link3 Multivariate analyses showed CD3

    T cells and CD4

    /CD8

    ratio were independent predictive factors for the OS (HR 0.295, 95% CI, 0.091-0.956; P=0.042 and HR 0.244, 95% CI, 0.065-0.920; P=0.037, respectively). Moreover, NLR negatively correlated with both levels of CD3

    T cells and CD4

    /CD8

    ratio (P<0.001, r=-0.398 and P=0.012, r=-0.280, respectively).

    The findings of our study suggest that preoperative CD3

    T cells and CD4

    /CD8

    ratio in peripheral blood are independent predictors for patients with ccRCC.
