Background: Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined. Methods: This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months. Conclusion This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Intravesical therapy is the gold standard in the treatment of nonmuscle invasive bladder cancer (NMIBC). Despite the efficacy of intravesical therapies, the best treatment options are not determined yet. Development in research of bladder cancer shows several new intravesical drugs and its delivery systems. Additionally, the novel knowledge of bladder cancer immune reaction improves and provides ambitious treatment strategies. The future of NMIBC therapy will be changed by the development of immunotherapy and new technologies for device-assisted treatment. This review focuses on recent advances in the intravesical therapy of NMIBC, viral gene therapy, new technology of intravesical chemotherapy, and drug delivery system.

Microbiomes are known to have a beneficial effect on human health by promoting the effective removal of improperly functioning immune cells and protecting the host from pathogen infection. On the other hand, these microbiomes are also known as the causative agent of numerous malignant tumors. Until now, the bladder has been regarded as aseptic, but the concept of the “sterile bladder” has been changed with the discovery of living bacteria embedded in the bladder with the recent development of polymerase chain reaction and culture techniques. This paper referred to the relationship between microbiome and bladder cancer. Microbiome will be able to be seen as a non-invasive biomarker to predict the success rate of intravesical bacillus Calmette-Guerin instillation treatment in patients of bladder cancer.

PURPOSE: To investigate the association of erectile dysfunction (ED), premature ejaculation (PE), and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in men with late-onset hypogonadism (LOH).MATERIALS AND METHODS: We reviewed the data of 408 enrolled men between January 2014 and January 2019. All participants completed the Androgen Deficiency in the Aging Male (ADAM), international index of erectile function-5 (IIEF-5), National Institutes of Health chronic prostatitis symptom index (NIH-CPSI), and premature ejaculation diagnostic tool (PEDT) questionnaires. Participants were divided by ADAM positive (ADAM+: Group 1) and ADAM negative (ADAM−: Group 2).RESULTS: Total of 289 subjects were in Group 1 and 119 were in Group 2. The mean age was 53.8±7.8 years. The mean total testosterone was 4.8±1.2 ng/dL and showed no differences between the groups (p=0.839). In Groups 1 and 2, ED (IIEF≤21) was identified in 233 (80.6%) versus 37 (31.1%), respectively (p<0.001). The prevalence of PE (PEDT≥9) was 112 (38.7%) versus 13 (10.9%) in Groups 1 and 2, respectively (p<0.001). However, PE (intravaginal ejaculation latency time<5 minutes) showed no differences between the groups (p=0.863). The incidence of chronic prostatitis (NIH-CPSI pain score≥4) showed significant differences with 49 (17.0%) versus 8 (6.7%) in Groups 1 and 2, respectively (p=0.007). IIEF-5 total score showed the significantly highest negative correlation (r=−0.313, p<0.001).CONCLUSIONS: Those who complained of LOH symptoms and positive results in the ADAM questionnaire need to be assessed concurrently with the above questionnaires. This could aid useful to detect of ED, PE, and chronic prostatitis co-occurrence.

Papillary renal cell carcinomas (RCCs) can be classified into 2 subtypes (types 1 and 2), depending on their characteristic cytogenetics, immunostaining profiles, and gene-expression profiles. Compared with type 1 papillary RCCs, type 2 papillary RCCs are relatively rare and show more aggressive features. For those reasons, they are associated with a worse prognosis. A 13-year-old patient was admitted to the hospital with right kidney mass. A laparoscopic radical nephrectomy was performed, and results of the histopathologic examination confirmed it to be type 2 papillary RCC. Type 2 papillary RCCs are rarely found in unilateral and multifocal forms, especially in adolescence. Here, we report the unique case of papillary RCC at a young age.

PURPOSE: To determine the role of metabolic syndrome (MetS) as a risk factor for acquired premature ejaculation (PE) after considering the various risk factors, such as lower urinary tract symptoms, erectile dysfunction, hypogonadism, and prostatitis. MATERIALS AND METHODS: From January 2012 to January 2017, records of 1,029 men were analyzed. We performed multivariate analysis to identify risk factors for PE, including the covariate of age, marital status, International Prostate Symptom Score, International Index of Erectile Function (IIEF) score, National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) score, serum testosterone levels, and all components of MetS. Acquired PE was defined as self-reported intravaginal ejaculation latency time ≤3 minutes, and MetS was diagnosed using the modified National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS: Of 1,029 men, 74 subjects (7.2%) had acquired PE and 111 (10.8%) had MetS. Multivariate analysis showed that the IIEF overall satisfaction score (odds ratio [OR]=0.67, p<0.001), NIH-CPSI pain score (OR=1.07, p=0.035), NIH-CPSI voiding score (OR=1.17, p=0.032), and presence of MetS (OR=2.20, p=0.022) were significantly correlated with the prevalence of acquired PE. In addition, the Male Sexual Health Questionnaire for Ejaculatory Dysfunction scores and ejaculation anxiety scores progressively decreased as the number of components of MetS increased. CONCLUSIONS: MetS may be an independent predisposing factor for the development of acquired PE. Effective prevention and treatment of MetS could also be important for the prevention and treatment of acquired PE.

PURPOSE: This study aimed to investigate the relationships between body mass index (BMI) and prostate-specific antigen (PSA) levels, international prostate symptom score (IPSS), quality of life (QoL), and prostate volume (PV). MATERIALS AND METHODS: Height, weight, PSA levels, PV, and IPSS were analyzed in 15,435 patients who underwent a prostate examination between 2001 and 2014. Patients aged <50 years or with a PSA level ≥10 ng/mL were excluded. The relationships between BMI and PSA, IPSS, QoL, and PV were analyzed by a scatter plot, one-way analysis of variance, and the Pearson correlation coefficient. RESULTS: The mean age was 71.95±7.63 years, the mean BMI was 23.59±3.08 kg/m2, the mean PSA level was 1.45±1.45 ng/mL, the mean IPSS was 15.53±8.31, the mean QoL score was 3.48±1.25, and the mean PV was 29.72±14.02 mL. PSA, IPSS, and QoL showed a tendency to decrease with increasing BMI, and there were statistically significant differences for each parameter (p≤0.001). PV showed a significant tendency to increase with BMI (p < 0.001). In the correlation analysis, BMI showed a statistically significant correlation (p < 0.001) with PSA, IPSS, and QoL, although the correlations were very weak. In contrast, BMI showed a significant correlation with PV (p < 0.001), with a meaningful Pearson correlation coefficient of 0.124. CONCLUSIONS: Higher BMI was associated with lower PSA levels and higher IPSS and QoL scores. Meanwhile, PV increased with BMI. Although obese individuals had a greater PV, obesity did not aggravate lower urinary tract symptoms.

PURPOSE: We studied the effects of alcohol administration on the corpus cavernosum (CC) using an animal model. MATERIALS AND METHODS: CC sections and the aortic ring of rabbits were used in an organ bath study. After acute alcohol administration, changes in blood alcohol concentration and electrical stimulation induced intracavernosal pressure/mean arterial pressure (ICP/MAP) percentage were compared in rats. Cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) levels in the CC were measured using immunoassays. After chronic alcohol administration, ICP/MAP percentage, cAMP and cGMP were compared in rats. Histological changes were examined using the Masson trichrome stain and the Sircol collagen assay. Endothelial nitric oxide synthase (eNOS) expression was examined using immunohistochemistry and Western blotting. RESULTS: Alcohol relaxed the CC in a dose-dependent manner, and the relaxation response was suppressed when pretreated with propranolol, indomethacin, glibenclamide, and 4-aminopyridine. In rats with acute alcohol exposure, the cAMP level in the CC was significantly greater than was observed in the control group (p<0.05). In rats with chronic alcohol exposure, however, changes in cAMP and cGMP levels were insignificant, and the CC showed markedly smaller areas of smooth muscle, greater amounts of dense collagen (p<0.05). Immunohistochemical analysis of eNOS showed a less intense response, and western blotting showed that eNOS expression was significantly lower in this group (p<0.05). CONCLUSIONS: Acute alcohol administration activated the cAMP pathway with positive effects on erectile function. In contrast, chronic alcohol administration changed the ultrastructures of the CC and suppressed eNOS expression, thereby leading to erectile dysfunction.

Carbon monoxide (CO) poisoning has increased rapidly in South Korea and may cause a variety of clinical effects. The most common complications are neurologic and neuropsychological disturbances. However, in rare cases, CO poisoning may also be associated with acute kidney injury and non-traumatic rhabdomyolysis. Here, we report a case of acute kidney injury and rhabdomyolysis complicating CO poisoning. A 32-year-old woman was admitted to our emergency department with dyspnea and confused consciousness after exposure to CO during a suicide attempt involving charcoal briquettes. Laboratory findings revealed a carboxyhemoglobin (COHb) level of 44.8%, a blood urea nitrogen level of 20.5 mg/dL, a serum creatinine level of 1.4 mg/dL, and a creatine phosphokinase level of 8,688.3 IU/L. Acute kidney injury and rhabdomyolysis complicating CO poisoning were diagnosed. This case was managed with normobaric oxygen therapy and hydration. The patient recovered completely with respect to renal function and muscle enzyme level, and COHb level returned to 0%.
