RESUMO
BACKGROUND: Abnormal hematologic parameters before patients undergoing prostate biopsy play a pivotal role in guiding the surgical management of prostate cancer (PCa) incidence. This study aims to establish the first nomogram for predicting PCa risk for better surgical management. METHODS: We retrospectively reviewed and analyzed the data including basic information, preoperative hematologic parameters, and imaging examination of 540 consecutive patients who underwent transrectal ultrasound (TRUS)-guided prostate biopsy for elevated prostate-specific antigen (PSA) in our medical center between 2017 and 2021. Logistic regression analysis was used to determine the risk factors for PCa occurrence, and the nomogram was constructed to predict PCa occurrence. Finally, the data including 121 consecutive patients in 2022 were prospectively collected to further verify the results. RESULTS: In retrospective analyses, univariate and multivariate logistic analyses identified that three variables including age, diabetes, and De Ritis ratio (aspartate transaminase/alanine transaminase, AST/ALT) were determined to be significantly associated with PCa occurrence. A nomogram was constructed based on these variables for predicting the risk of PCa, and a satisfied predictive accuracy of the model was determined with a C-index of 0.765, supported by a prospective validation group with a C-index of 0.736. The Decision curve analysis showed promising clinical application. In addition, our results also showed that the De Ritis ratio was significantly correlated with the clinical stage of PCa patients, including T, N, and M stages, but insignificantly related to the Gleason score. CONCLUSIONS: The increased De Ritis ratio was significantly associated with the risk and clinical stage of PCa and this nomogram with good discrimination could effectively improve individualized surgical management for patient underdoing prostate biopsy.

Researches had proven that the occurrence of bladder cancer (BC) is much higher in men than those in women, which induced us to explore whether androgen plays a role in BC. A total of 147 patients who were diagnosed with primary BC by histopathological biopsy were included. Meanwhile 154 non-tumor patients were matched as the control group. The continuous variables were expressed as median (interquartile range, IQR) and compared by Mann-Whitney U test, for the reason that the data were not matched the requirementsthe of normal test. A Chi-square test was used to compare the categorical variables, which were expressed as frequency (percentage). Meanwhile univariate and multivariate logistic regression was done to further evaluating the potential independent factor of BC. P < 0.05 was considered statistically significant. Univariate multivariate analyse showed significant difference between two groups in hemoglobin (OR 0.979, 95% CI 0.968-0.991, P < 0.001), hypertension (OR 3.026, 95% CI 1.731-5.288, P < 0.001), diabetes (OR 4.294, 95% CI 1.887-9.771, P = 0.001) and smoking (OR 1.729, 95% CI 1.096-2.729, P = 0.019). Furthermore, multivariate logistic regression analysis was conducted to eliminate the interference of confounding factors, which showed that testosterone seems to be great correlated with the BC (OR 1.002, 95% CI 1.000-1.003, P = 0.017). Similar results were also found in hemoglobin (OR 0.981, 95% CI 0.968-0.993, P = 0.002), hypertension (OR 2.780, 95% CI 1.509-5.120, P = 0.001), diabetes (OR 3.313 95% CI 1.373-7.991, P = 0.008) and smoking (OR 1.938, 95% CI 1.184-3.174, P = 0.009). As a conclusion, our study showed that there was significant correlation between serum total testosterone levels and the occurrence of BC, similar results were shown in hemoglobin, hypertension, diabetes and smoking.

PURPOSE: Hysterectomy is one of the most common types of gynecological operations and it is associated with numerous postoperative complications. Few studies have reported a definitive association between hysterectomy and kidney stone disease (KSD). This study aimed to explore whether hysterectomy increases the risk of KSD. METHODS: This is a cross-sectional study that used six continuous cycles of data obtained from the National Health and Nutrition Examination Survey from 2007 to 2018. The correlations between hysterectomy or age at hysterectomy and the prevalence of KSD were assessed using weighted multivariable-adjusted logistic regression. Further, five methods of two-sample Mendelian randomization (MR) were applied to decrease bias and infer causality in the observational study. RESULTS: After adjusting for potential confounders, hysterectomy (OR: 1.37, 95% CI 1.04-1.81) was found to be positively associated with the prevalence of KSD, whereas age at hysterectomy was found to be negatively associated with the prevalence of KSD (OR: 0.96, 95% CI: 0.94-0.98). In the inverse-variance weighted method, MR analyses suggested that genetically predicted hysterectomy is causally associated with a higher risk of KSD (OR: 11.961, 95% CI 1.12-1.28E2). CONCLUSIONS: Hysterectomy could increase the risk of KSD. Younger age at hysterectomy is associated with a higher risk of KSD. Further prospective cohort studies with larger sample sizes and longer follow-up times are needed.

PURPOSE: Oxidative stress plays a crucial role in the pathogenesis of urinary incontinence (UI). This study aimed to assess the association between the oxidative balance score (OBS) and UI in adult females in the United States. METHODS: The study utilized data from the National Health and Nutrition Examination Survey database, spanning from 2005 to 2018. Weighted multivariate logistic regression, subgroup analyses, and restricted cubic spline regression were conducted to determine the odds ratio (OR) and 95% confidence intervals (95% CI) regarding the association between OBS and UI. Sensitivity analyses were performed to assess the robustness of the findings. RESULTS: A total of 7304 participants were enrolled in this study. After adjusting for potential confounders, participants with lower OBS were found to have a higher likelihood of experiencing stress, urge, and mixed incontinence (OR, 0.986; 95% CI 0.975-0.998; p = 0.022; OR, 0.978; 95% CI 0.963-0.993; p = 0.004; and OR, 0.975; 95% CI 0.961-0.990; p = 0.001). Lifestyle factors were strongly associated with the prevalence and frequency of UI. The results remained consistent, and no significant interaction effects were observed in the subgroup analyses. The prevalence of three types of UI exhibited a nonlinear inverted U-shaped trend with increasing in OBS and dietary OBS (p for nonlinear < 0.05). CONCLUSION: Among females, the higher the OBS, the lower the prevalence of UI. Therefore, dietary and lifestyle-related antioxidant therapy for females with UI should receive attention and be subject to further investigation.

Methods: The Web of Science Core Collection database was searched using the search terms "renal cancer", "kidney neoplasms", "kidney cancer", and "targeted therapy", and all publications were extracted. VOSviewer version 1.6.18 was used to complete the visual analysis based on the information of publications, including author, journal, subject, year, and institution. Results: A total of 1,136 studies related to TT for RC were found. The top journals in this field were the Journal of Clinical Oncology, Annals of Oncology, and European Urology. Among them, the Journal of Clinical Oncology had the highest number of publications (n=35). In terms of country, the United States had the highest number of publications (n=366). The main document type was article, which accounted for 64.26% of the total publications. Conclusions: To the best of our knowledge, this is the first bibliometric analysis related to TT for RC. The annual number of publications has exhibited a steady growth trend, with the United States having the greatest contribution in this field. Through an analysis of a keyword time density map, we identified that hypoxia-inducing factor-1, drug resistance and therapeutic targets are the research hotspots and trends in this field.
RESUMO
INTRODUCTION: Cholelithiasis represents a known risk factor for digestive system neoplasm. Few studies reported the association between cholelithiasis and the risk of prostate cancer (PCa), and the results were controversial. METHODS: We reviewed the medical records of the Second Affiliated Hospital of Chongqing Medical University Hospital to perform a retrospective matched case-control study, which included newly diagnosed 221 PCa patients and 219 matched controls. Logistic regression was applied to compare cholelithiasis exposure and adjusted for confounding factors. Additionally, we conducted a meta-analysis pooling this and published studies further to evaluate the association between cholelithiasis and PCa risk. Related ratio (RR) and 95% confidence interval (95%CI) were used to assess the strength of associations. RESULTS: Our case-control study showed that cholelithiasis was associated with a higher incidence of PCa (OR = 1.87, 95% CI: 1.06-3.31) after multivariable adjustment for covariates. The incidence of PCa was increased in patients with gallstones but not cholecystectomy. 7 studies involving 80,403 individuals were included in the meta-analysis. Similarly, the results demonstrated that cholelithiasis was associated with an increased risk of PCa (RR = 1.35, 95%CI: 1.17-1.56) with moderate-quality evidence. Cholelithiasis patients with low BMI increased the PCa incidence. Moreover, Subgroup analysis based on region showed that cholelithiasis was associated with PCa in Europe (RR = 1.24, 95%CI 1.03-1.51) and Asia (RR = 1.32, 95%CI 1.24-1.41). CONCLUSIONS: The results suggested an association between cholelithiasis and the risk of PCa. There was no significant relationship between cholecystectomy therapy and PCa risk. Further cohort studies should be conducted to demonstrate the results better.

To explore the association between male infertility and hypertension risk, a meta-analysis and systematic review was conducted. Observational studies were sought in Medline, PubMed, EMBASE, Web of Science, and China National Knowledge Infrastructure up to April 30, 2021. Two independent reviewers selected available studies and extracted the data. The association between male infertility and hypertension risk was estimated by calculating the relative risk (RR) and 95% confidence interval (95% CI) using Stata12.0 statistical software. A total of seven studies were included in this meta-analysis, including 102,152 patients and 636,645 healthy individuals. The results demonstrated that male infertility was significantly associated with increased hypertension incidence (RR = 1.08; 95% CI 1.02-1.14; p = 0.004), with moderate-quality evidence. A subgroup analysis based on region showed that a positive association was observed in Europe but not the United States or Asia. This positive association was further confirmed in a cohort study, but not in a case-control study. After adjusting for potential confounders, male infertility was still significantly associated with hypertension risk (RR = 1.06, 95% CI 1.03-1.09). In conclusion, our findings suggest that male infertility increases the risk of hypertension incidence. However, further studies are needed to provide more conclusive evidence.

To predict disease outcome in muscle-invasive bladder cancer (MIBC), we constructed a prognostic autophagy-related (PAR) lncRNA signature. Comprehensive bioinformatics analyses were performed using data from TCGA and GTEx databases. Univariate Cox, and least absolute shrinkage and selection operator regression analyses were also performed, based on differentially expressed genes, to identify PAR-related lncRNAs to establish the signature. Furthermore, the Kaplan-Meier OS curve and receiver operating characteristic curve analyses were performed and a nomogram was constructed, all of which together confirmed the strong predictive ability of the constructed signature. Patients with MIBC were then divided into high- and low-risk groups. Gene enrichment and immune infiltration analyses revealed the potential mechanisms in MIBC. We also further evaluated the signature of molecules related to immune checkpoints and the sensitivity toward chemotherapeutic agents and antitumor-targeted drugs to find better treatment prescriptions. We identified a number of PAR-related lncRNA signatures, including HCP5, AC024060.1, NEAT1, AC105942.1, XIST, MAFG-DT, and NR2F1-AS1, which could be valuable prognostic tools to develop more efficient, individualized drug therapies for MIBC patients.

INTRODUCTION: The incidence and outcomes of bladder cancer (BCa) have apparent sex differences. Various observational studies have demonstrated that the age of menarche might be associated with female BCa. To explore this relationship, a meta-analysis and systematic review were performed based on available studies. MATERIAL AND METHODS: A systematic search was performed in PubMed, Embase, and Web of Science for studies published up to October 1, 2021. Two reviewers independently extracted related data between age of menarche and BCa risk from the included studies. The Newcastle-Ottawa quality assessment scale was applied to evaluate the quality of the studies. The relative risk (RR) ratio and its 95% confidence interval (CI) were then calculated. RESULTS: A total of 12 studies containing 3,719 BCa cases and 1,350,207 women, were included in this meta-analysis. The pooled data showed that the age of menarche was not significantly associated with BCa risk (RRâ¯=â¯0.96, 95% CI: 0.85-1.08), although the evidence was of moderate quality. Similar results were observed in case-control (RRâ¯=â¯1.33, 95% CIâ¯=â¯0.77-2.21) and cohort studies (RRâ¯=â¯0.95, 95% CIâ¯=â¯0.84-1.07). Moreover, subgroup analyses based on study quality, population, exposure assessment, and several potential important confounders and risk factors revealed similar results. No evidence of publication bias and significant heterogeneity was found among these studies. Furthermore, a random-effects dose-response meta-regression model was established, which revealed negative results. CONCLUSIONS: Our findings suggested that the age of menarche was not associated with BCa risk in women. However, these findings needed to be further confirmed given the limitations and potential biases.
