The sedation outcomes associated with dexmedetomidine compared with those of propofol during drug-induced sleep endoscopy (DISE) remains unclear. Electronic databases (i.e., the Cochrane controlled trials register, Embase, Medline, and Scopus) were searched from inception to 25 December 2020 for randomized controlled trials (RCTs) that evaluated the sedation outcomes with dexmedetomidine or propofol in adult patients diagnosed with obstructive sleep apnea (OSA) receiving DISE. The primary outcome was the difference in minimum oxygen saturation (mSaO2). Five RCTs (270 participants) published between 2015 and 2020 were included for analysis. Compared with dexmedetomidine, propofol was associated with lower levels of mSaO2 (mean difference (MD) = −7.24, 95% confidence interval (CI) −12.04 to −2.44; 230 participants) and satisfaction among endoscopic performers (standardized MD = −2.43, 95% CI −3.61 to −1.26; 128 participants) as well as a higher risk of hypoxemia (relative ratios = 1.82, 95% CI 1.2 to 2.76; 82 participants). However, propofol provided a shorter time to fall asleep and a lower risk of failed sedation compared with dexmedetomidine. No significant difference was found in other outcomes. Compared with propofol, dexmedetomidine exhibited fewer adverse effects on respiratory function and provided a higher level of satisfaction among endoscopic performers but was associated with an elevated risk of failed sedation.

Prostate cancer is featured by its heterogeneous nature, which indicates a different prognosis. Castration-resistant prostate cancer (CRPC) is a hallmark of the treatment-refractory stage, and the median survival of patients is only within two years. Neuroendocrine prostate cancer (NEPC) is an aggressive variant that arises from de novo presentation of small cell carcinoma or treatment-related transformation with a median survival of 1–2 years from the time of diagnosis. The epigenetic regulators, such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), have been proven involved in multiple pathologic mechanisms of CRPC and NEPC. LncRNAs can act as competing endogenous RNAs to sponge miRNAs that would inhibit the expression of their targets. After that, miRNAs interact with the 3’ untranslated region (UTR) of target mRNAs to repress the step of translation. These interactions may modulate gene expression and influence cancer development and progression. Otherwise, epigenetic regulators and genetic mutation also promote neuroendocrine differentiation and cancer stem-like cell formation. This step may induce neuroendocrine prostate cancer development. This review aims to provide an integrated, synthesized overview under current evidence to elucidate the crosstalk of lncRNAs with miRNAs and their influence on castration resistance or neuroendocrine differentiation of prostate cancer. Notably, we also discuss the mechanisms of lncRNA–miRNA interaction in androgen receptor-independent prostate cancer, such as growth factors, oncogenic signaling pathways, cell cycle dysregulation, and cytokines or other transmembrane proteins. Conclusively, we underscore the potential of these communications as potential therapeutic targets in the future.

Intravesical botulinum toxin type A (BoNT-A) injection has been recognized as the standard treatment for refractory overactive bladder (OAB). However, its therapeutic efficacy and safety have not been thoroughly reviewed in elderly patients. This study aims to provide treatment outcomes for patients aged ≥75 years, and to identify factors associated with unfavorable outcomes. Patients receiving intradetrusor injections of 100 U onabotulinumtoxinA for refractory OAB between 2011 and 2021 were retrospectively reviewed. Urodynamic parameters, underlying comorbidities, subjective success, and unfavorable outcomes were assessed. A total of 192 patients were included, and 65 of them were classified into the elderly group. For the elderly group, 60.0% experienced subjective dryness, and 84.6% remained subjective success at 6 months after the injections. The prevalence rates of common unfavorable outcomes, including urinary tract infections, large post-void residual urine volume, and urinary retention, were 9.2%, 27.7%, and 12.3%, respectively. Multivariate analysis revealed that female, baseline urodynamic parameters, and diabetes mellitus were associated with unfavorable outcomes in the elderly group. Intravesical BoNT-A injections provide comparable therapeutic efficacy and safety concerns in elderly patients with refractory OAB. A thorough consultation for treatment benefits and possible adverse events is mandatory before the procedure.

Purpose: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes.Methods: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery.Results: The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor.Conclusions: In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

IMPORTANCE: New medications for type 2 diabetes (T2D) control, such as sodium-glucose cotransporter-2 inhibitors (SGLT2Is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs), have emerged. However, the US Food and Drug Administration has warned about potential risks of Fournier gangrene, a severe genital infection associated with SGLT2I use.OBJECTIVE: To determine comparative risks of male external genital infections (MEGIs) in adult male patients with T2D treated with SGLT2Is.DESIGN, SETTING, AND PARTICIPANTS: A population-based cohort study analyzing Taiwan’s National Health Insurance Research Database was conducted to evaluate the MEGI risk in adult male patients with T2D newly treated with SGLT2Is between January 1, 2009, and December 31, 2020. Patients newly treated with GLP-1RAs were chosen during the same period for the active-comparator group, and propensity scores with inverse probability of treatment weighting were applied to balance the baseline characteristics between the 2 treatment groups. Data analyses were conducted between February 2023 and April 2025.EXPOSURES: Treatment with SGLT2Is or GLP-1RAs.MAIN OUTCOMES AND MEASURES: The primary outcome was the incidence of MEGI, identified using International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes. To examine the result consistency, subgroup analyses based on age (older or younger than 60 years), diabetes severity (insulin use or not), and kidney function were conducted.RESULTS: The study included 239 757 patients; 224 360 initiated SGLT2Is (mean [SD] age, 58.4 [12.3] years) and 15 397 initiated GLP-1RAs (mean [SD] age, 58.1 [13.6] years). Compared with the GLP-1RA group, the SGLT2I group had a significantly increased risk of MEGI (hazard ratio [HR], 1.65; 95% CI, 1.59-1.71). The subgroup analyses indicated an increased risk of MEGI in the SGLT2I group among patients younger than 60 years (HR, 2.04; 95% CI, 1.58-2.65), those with an estimated glomerular filtration rate of 60 mL/min/1.73 m² (HR, 1.69; 95% CI, 1.34-2.15), and those with hemoglobin A_1c below 7% (HR, 3.22; 95% CI, 1.71-6.03).CONCLUSIONS AND RELEVANCE: These findings suggest that SGLT2Is are associated with a higher risk of MEGI in adult male patients with T2D, compared with GLP-1RAs. Clinicians should be cautious when prescribing SGLT2Is in male patients with T2D.

Background: To investigate the cancer types and risk factors of secondary primary malignancy (SPM) in patients with upper tract urothelial carcinoma (UTUC) in Taiwan. Methods: Using National Health Insurance Research Dataset and catastrophic illness registry, we enrolled newly diagnosed UTUC patients from 2000 to 2013. Those without catastrophic illness registration were excluded from the study. The cancer types and hazard ratios (HRs) of subsequent SPMs were calculated according to the antecedent malignancy. We analyzed the risk factors for developing SPMs using multivariate Cox proportional hazard models. Results: A total of 9050 UTUC patients were registered and 2187 (24.2%) patients developed SPMs during the study period. As compared with primary UTUC, the relative risk ratios of SPM was 2.5 folds and 18% higher in those with antecedent non-UC malignancy and with bladder cancer history, respectively. Totally, 387 (37.8%) of 1022 UTUC patients with antecedent non-UC malignancy developed subsequent SPM after UTUC diagnosis. The antecedent and subsequent cancer types are similar and kidney cancer is most common, followed by hepatoma. Multivariate analysis showed that a history of antecedent non-UC malignancy is the most unfavorable factor for SPM development (HR, 2.50; 95% CI, 2.23-2.81), followed by liver disease, male gender, antecedent bladder cancer history, age >= 75 years, and chronic kidney disease. Conclusions: Our study, conducted in Taiwan and involving 9050 UTUC patients, meticulously examined the types of SPM and the associated risk factors. Our research unearthed several pivotal discoveries: a preceding history of non-UC malignancies emerged as the single most influential factor contributing to the occurrence of subsequent cancers, followed by liver disease, male gender, antecedent bladder cancer history, age >= 75 years, and chronic kidney disease. Futhermore, kidney cancer emerged as the predominant subsequent malignancy, closely trailed by hepatoma..
