RESUMEN
AIMS: To examine the association between testosterone deficiency (TD) and nocturia in males, with specific attention to age and cardiovascular disease (CVD) comorbidity. METHODS: This cross-sectional study utilized the National Health and Nutrition Examination Survey (NHANES) data from 2011 to 2016, assessing 6137 adult male participants. TD was defined by a serum total testosterone (TT) concentration less than 300 ng/dL. Nocturia was determined based on participants' responses to a standard NHANES question regarding the frequency of urination during the night. RESULTS: The study observed a significant association between TD and nocturia (adjusted odds ratio [95% confidence interval] = 1.211 [1.060-1.384], p = 0.005). Moreover, a U-shape pattern was noted in the relationship between serum TT concentration and the relative odds of nocturia. Subgroup analysis revealed a robust correlation between TD and nocturia in those over 60 years old, and those with hypertension, dyslipidemia, and CVDs. CONCLUSION: Our findings suggest a positive correlation between TD and nocturia, particularly among elderly individuals with CVD. This association underscores the potential therapeutic significance of addressing TD in the management of nocturia. Furthermore, longitudinal studies are needed to establish a causal relationship between TD and nocturia.

AIMS: To use machine learning algorithms to develop a model to accurately predict treatment responses to mirabegron or antimuscarinic agents in patients with overactive bladder (OAB), using real-world data from the FAITH registry (NCT03572231). METHODS: The FAITH registry data included patients who had been diagnosed with OAB symptoms for at least 3 months and were due to initiate monotherapy with mirabegron or any antimuscarinic. For the development of the machine learning model, data from patients were included if they had completed the 183-day study period, had data for all timepoints and had completed the overactive bladder symptom scores (OABSS) at baseline and end of study. The primary outcome of the study was a composite outcome combining efficacy, persistence, and safety outcomes. Treatment was deemed "more effective" if the composite outcome criteria for "successful," "no treatment change," and "safe" were met, otherwise treatment was deemed "less effective." To explore the composite algorithm, a total of 14 clinical risk factors were included in the initial data set and a 10-fold cross-validation procedure was performed. A range of machine learning models were evaluated to determine the most effective algorithm. RESULTS: In total, data from 396 patients were included (266 [67.2%] treated with mirabegron and 130 [32.8%] treated with an antimuscarinic). Of these, 138 (34.8%) were in the "more effective" group and 258 (65.2%) were in the "less effective" group. The groups were comparable in terms of their characteristic distributions across patient age, sex, body mass index, and Charlson Comorbidity Index. Of the six models initially selected and tested, the decision tree (C5.0) model was chosen for further optimization, and the receiver operating characteristic of the final optimized model had an area under the curve result of 0.70 (95% confidence interval: 0.54-0.85) when 15 was used for the min n parameter. CONCLUSIONS: This study successfully created a simple, rapid, and easy-to-use interface that could be further refined to produce a valuable educational or clinical decision-making aid.

OBJECTIVE: To preoperative factors that could predict the persisting storage symptoms after Holmium laser enucleation of the prostate (HoLEP). METHODS: Medical records of 257 patients who underwent HoLEP between December 2014 and January 2021 were reviewed. Participants with a follow-up period exceeding 6 months were included. Preoperative data, including International Prostate Symptom Score (IPSS), uroflowmetry, prostate size, and prostate-specific antigen, were collected. All participants underwent a preoperative urodynamic study. The correlation between perioperative variables and postoperative medication therapy (antimuscarinics or beta-3 agonists) was assessed. RESULTS: Out of 257 participants in the study, 46 (18.6%) were allocated to the medication group, of which 25 (54.3%) initiated medication therapy postoperatively. The medication group showed worse postoperative IPSS storage symptom score and quality of life score compared to the medication-free group (p = 0.048 and p = 0.002, respectively), but no significant differences were observed in complications or operative variables. In the de-novo medication group, patients had lower preoperative Qmax , larger prostate volume, and smaller maximum cystometric capacity (MCC) compared to the persisting medication group (p = 0.020, p = 0.009, and p = 0.008, respectively). Overactive bladder (OAB) history, terminal detrusor overactivity (DO), and IPSS urgency item were identified as possible predictive factors for post-HoLEP medication use. CONCLUSIONS: Preoperative factors such as OAB history, terminal DO, and IPSS urgency item may predict the need for post-HoLEP medication therapy. Further follow-up studies are warranted to understand the characteristics of the de-novo medication group due to the significant discomfort it can cause to patients.

AIMS: To investigate the association of nocturia with the prevalence of cardiovascular disease (CVD) using the National Health and Nutrition Examination Survey (NHANES) data. METHODS: Among the 40 790 individuals who participated in NHANES from 2005 to 2012, 14 114 adults were analyzed in this study. A participant was considered to have nocturia if they have two or more voiding episodes nightly. In addition, participants with nocturia more than four times in a day were considered to have severe nocturia. A multivariate logistic regression analysis with adjustment for confounding variables, including age, sex, race, body mass index (BMI), smoking status, alcohol consumption, sleeping time, dyslipidemia, hypertension, and diabetes mellitus was performed with 1:1 propensity score matching (PSM). RESULTS: Nocturia occurred in 4610 individuals (32.7%). The prevalence of CVD was significantly higher in men, older individuals, those with higher BMI, smokers, and those with diabetes, hypertension, and hyperlipidemia. There was also a significantly higher prevalence of nocturia in the participants with CVD. Multivariate analysis showed that odds ratios (ORs) of mild and severe nocturia for CVD were 1.23 (95% confidence interval [CI]: 1.08-1.39) and 1.74 (95% CI: 1.39-2.17), respectively. After 1:1 PSM, the ORs of mild and severe nocturia were 1.27 (95% CI: 1.10-1.48) and 1.73 (95% CI: 1.33-2.26), respectively, showing statistical significance. CONCLUSION: Data from the NHANES indicate that CVD was significantly associated with the prevalence of nocturia, after taking major confounding factors into account. Furthermore, the risk for CVD increases with increasing nocturia severity.

PURPOSE: Postmicturition dribbling (PMD) is a stressful symptom in middle-aged men characterized by urinary leakage after the completion of normal voiding. Appropriate treatments have not yet been introduced. This study assessed the efficacy of treatment of PMD with 75 mg udenafil daily. MATERIALS AND METHODS: The study included 138 men with regular sexual lifestyles. The Hallym PMD questionnaire (HPMDQ) was used to assess PMD symptoms. After all basic examinations, patients were randomly assigned to either udenafil or placebo. Patients completed the surveys, uroflowmetry (UFM), a bladder scan, and the paper test during the follow-up visit. RESULTS: The mean age of the patients was 57.6 years. PMD with one of every three urinations was experienced by 59 patients (42.8%), whereas 45 patients (32.6%) experienced PMD with two of every three urinations. PMD with every urination was experienced by 34 patients (24.6%). More than half of the patients (89 patients, 65.4%) indicated that persistent PMD symptoms would likely result in moderate to severe discomfort in their daily activities. As time passed, the udenafil group showed significant improvement in PMD symptoms (p = 0.001). CONCLUSION: Udenafil 75 mg once daily can be an effective treatment for patients with PMD symptoms.

OBJECTIVES: For many years, creation of an orthotopic neobladder after cystectomy has been popular. In the present study, we measured the extent of metabolic acidosis in patients with ileal neobladders compared with ileal conduits and defined risk factors for development of metabolic acidosis. METHODS: We retrospectively studied 95 patients, who underwent radical cystectomy and urinary diversion to treat invasive bladder cancer from January 2001 to December 2014 at Hallym University Kangnam Sacred Heart Hospital, through investigation of acid-base balance, serum electrolyte levels and renal function one month and one year after operation. RESULTS: One month after the operation, metabolic acidosis was found from 18 patients (31.0%) in an ileal neobladder group and from 4 (14.8%) in an ileal conduits group. One year after the operation, the numbers became 11 (22.9%) and 2 (10.0%), respectively. However, there was not a statistical difference. The blood biochemical profiles of the two groups did not differ significantly after urinary diversion. Logistic analysis revealed that lower estimated glomerular filtration rate (eGFR) was associated with metabolic acidosis at one month (odds ratio, OR = 0.94 [0.91-0.97]; p < 0.001) and one year (OR = 0.94 [0.92-0.97]; P = 0.001) after urinary diversion. In multivariate analysis, lower eGFR is a significant risk factor for metabolic acidosis at one month. CONCLUSIONS: Patients with ileal neobladders and conduits are at the similar risk of metabolic acidosis. A close association between renal function and development of metabolic acidosis was observed, especially stronger in an early period after operation.

PURPOSE: To examine an association between the overactive bladder symptom score (OABSS) and neuropsychological parameters. Moreover, we investigate the factors that affect each item in the questionnaire. MATERIALS AND METHODS: A total of 376 patients (males: 184; females: 192) with probable Alzheimer's disease (AD) were recruited. Cognitive testing was conducted using the Mini Mental Status Examination (MMSE), Clinical Dementia Rating (CDR) scale, Global Deterioration Scale (GDS), and Barthel Activities of Daily Living (ADL). Lower urinary tract symptom (LUTS) was assessed using OABSS and voiding diary. RESULTS: The prevalence of overactive bladder (OAB) (defined as OABSS ≥3 with na urgency score of ≥2) in patients with AD was 72.6%. Among the OAB subjects, the most common severity of symptom was moderate (72.6%), followed by mild (21.2%), and severe (5.8%). It was found that OABSS had a very high correlation with aging (r=0.75; p<0.001). When compared with neuropsychological parameters, it was found that OABSS was highly correlated with the CDR scores (r=0.446; p<0.001). However, no significant correlation was found between the changes in OABSS scores and those in other neuropsychological parameters. Based on the individual symptom scores, urgency incontinence was highly correlated with the CDR scores (r=0.43; p<0.001). CONCLUSIONS: OABSS is a useful tool in assessing AD patients with LUTS. There was a consistent positive association between OABSS severity, including urgency incontinence, and CDR scores.

OBJECTIVE: To assess factors associated with detrusor overactivity in urinary incontinence patients with Alzheimer's disease, and to determine the correlation between the degree of Alzheimer's disease and the presence of detrusor overactivity. METHODS: A total of 144 Alzheimer's disease patients (48 men, 96 women; aged 56-97 years) with urinary incontinence were enrolled in this protocol. Cognitive testing was carried out using the Mini-Mental State Examination, the Clinical Dementia Rating scale, the Global Deterioration Scale and Barthel's Activities of Daily Living. Urinary incontinence was assessed using a frequency-volume chart and the Incontinence Questionnaire on Urinary Incontinence Short Form. All study participants had a urodynamic study carried out. RESULTS: Based on the Incontinence Questionnaire on Urinary Incontinence Short Form, the most common type of urinary incontinence was urge urinary incontinence followed by enuresis in men, whereas women most commonly complained of urge urinary incontinence followed by stress urinary incontinence. Detrusor overactivity was found in 57.6% of patients (25 men, 58 women) on urodynamic study. No statistical differences were found between those with and without detrusor overactivity in terms of age, sex or duration of education. No significant correlation was found between changes in Incontinence Questionnaire on Urinary Incontinence Short Form scores and those in the Mini-Mental State Examination, Clinical Dementia Rating and Barthel's Activities of Daily Living status. Multiple logistic regression analysis showed the presence of detrusor overactivity could be predicted using Clinical Dementia Rating and Barthel's Activities of Daily Living scores (P < 0.05). CONCLUSIONS: The most common type of urinary incontinence in patients with Alzheimer's disease is urge urinary incontinence. Clinical Dementia Rating and Barthel's Activities of Daily Living predict the severity of detrusor overactivity in this patient population.

PURPOSE: With the recent rising interest in artificial intelligence (AI) in medicine, many studies have explored the potential and usefulness of AI in urological diseases. This study aimed to comprehensively review recent applications of AI in urologic oncology. MATERIALS AND METHODS: We searched the PubMed-MEDLINE databases for articles in English on machine learning (ML) and deep learning (DL) models related to general surgery and prostate, bladder, and kidney cancer. The search terms were a combination of keywords, including both "urology" and "artificial intelligence" with one of the following: "machine learning," "deep learning," "neural network," "renal cell carcinoma," "kidney cancer," "urothelial carcinoma," "bladder cancer," "prostate cancer," and "robotic surgery." RESULTS: A total of 58 articles were included. The studies on prostate cancer were related to grade prediction, improved diagnosis, and predicting outcomes and recurrence. The studies on bladder cancer mainly used radiomics to identify aggressive tumors and predict treatment outcomes, recurrence, and survival rates. Most studies on the application of ML and DL in kidney cancer were focused on the differentiation of benign and malignant tumors as well as prediction of their grade and subtype. Most studies suggested that methods using AI may be better than or similar to existing traditional methods. CONCLUSIONS: AI technology is actively being investigated in the field of urological cancers as a tool for diagnosis, prediction of prognosis, and decision-making and is expected to be applied in additional clinical areas soon. Despite technological, legal, and ethical concerns, AI will change the landscape of urological cancer management.

PURPOSE: The purpose of this study was to explore the association between benign prostatic hyperplasia (BPH) and the incidence of falls from the perspective of geriatric morbid conditions. METHODS: Data were sourced from the triennial National Survey of Older Koreans conducted by the Ministry of Health and Welfare (2017-2020). In total, 8,135 male participants aged 65 and older were included, and information was gathered through questionnaires and physical measurements. Logistic regression analysis was utilized to determine the impact of BPH on the risk of falls, and subgroup analyses were conducted to examine the influence of BPH on specific types of falls. RESULTS: Of the participants, 15.2% (1,238 of 8,135) reported that their BPH treatment exceeded 3 months, and 8.0% (648 of 8,135) reported experiencing falls, with 61.4% (398/648) of these falls resulting in injuries. A significant association was identified between BPH and both falls (odds ratio [OR], 1.798; 95% confidence interval [CI], 1.479-2.185) and falls with injuries (OR, 2.133; 95% CI, 1.689-2.694). A subgroup analysis indicated a correlation between BPH and falls in groups having one (OR, 1.912; 95% CI, 1.356-2.694) and 2 or more conditions (OR, 1.856; 95% CI, 1.455-2.367) involving visual and auditory impairments, cognitive decline, depression, lower motor weakness, and limitations in daily activities. CONCLUSION: The findings indicate that BPH contributes to the incidence of falls among older men, particularly those with comorbid conditions. Considering the heightened fall risk among elderly individuals suffering from multiple morbidities, particularly those with BPH, targeted interventions are essential for mitigating the risk of falls in this vulnerable group.
RESUMEN
INTRODUCTION: This study aimed to assess overactive bladder (OAB) treatment patterns and factors associated with effectiveness and persistence. METHODS: A prospective, longitudinal, observational registry study of adults starting OAB therapy with mirabegron or antimuscarinics was undertaken. Primary endpoints were time from treatment initiation to discontinuation/switching; proportion who discontinued/switched; and reasons for discontinuation/switching. Secondary endpoints included OAB Symptom Score (OABSS), OAB Questionnaire: Short Form, and OAB Bladder Assessment Tool scores; factors associated with effectiveness and persistence; and safety. RESULTS: In total, 556 patients initiating mirabegron and 250 initiating antimuscarinics were enrolled. There was no treatment switch, change, or discontinuation in 68.5% of the mirabegron initiator group and median time to treatment change was not reached. Mean initial treatment duration was 130.8 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, and patients with mild and moderate OAB had significantly better persistence with mirabegron than those with severe OAB. Urinary tract infection was the most common adverse event with mirabegron. There was no treatment switch, change, or discontinuation in 60.4% of the antimuscarinics initiator group and median time to treatment change was not reached. Solifenacin was the most frequent initial treatment (66.0%). Mean treatment duration was 122.2 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, while patients with OAB medication in the 12 months before enrollment had significantly better persistence with antimuscarinics than those with no previous OAB medication. Dry mouth was the most common adverse event with antimuscarinics. CONCLUSIONS: Mirabegron and solifenacin were commonly prescribed as first-line OAB medications. There was no treatment switch, change, or discontinuation in more than 60% of the mirabegron initiator and antimuscarinics initiator groups. Mean initial treatment duration was 130.8 days and 122.2 days for mirabegron and antimuscarinics, respectively. Graphical Abstract available for this article. TRIAL REGISTRATION: ClinicalTrials.gov NCT03572231.

INTRODUCTION: There is partial evidence to support the use of phophodiesterase-5 inhibitor (PDE5-I) for the treatment of premature ejaculation (PE). AIM: We compared on-demand dosing of dapoxetine alone and combined with mirodenafil in subjects with lifelong PE and without erectile dysfunction (ED). METHODS: Our prospective, randomized, double-blind, placebo-controlled, multicenter trial enrolled 118 subjects with lifelong PE without ED. PE was diagnosed using Diagnostic andâ Statisticalâ Manual ofâ Mentalâ Disorders, fourth edition, text revision. Patients were divided into two groups: dapoxetine 30 mg plus placebo (group A, n=56) and dapoxetine 30 mg plus mirodenafil 50 mg (group B, n=62). MAIN OUTCOME MEASURES: During 12 weeks, intravaginal ejaculatory latency time (IELT) and the time from foreplay to beginning intercourse (FTIT) with a stopwatch, and Premature Ejaculation Profile (PEP) were measured. Overall sexual act time (OSAT; sum of FTIT and IELT) was calculated. Any treatment-emergent adverse events (TEAEs) were also recorded. RESULTS: Over 12 weeks, IELT, OSAT, and PEP index score significantly improved in group B compared with group A (increased geometric mean IELT in group A and B=3.6 and 6.1 minutes, P=0.026; increased geometric mean OSAT in group A and B=5.5 and 9.9 minutes, P=0.012; increased median PEP index score in group A and B=1.0 and 1.3, P=0.046). However, there was no significant difference between two groups with respect to improvement of FTIT (P=0.147). TEAEs did not differ between groups (all P>0.05), and there was no serious adverse event in any subjects. CONCLUSIONS: Low dose of dapoxetine combined with mirodenafil showed better results in terms of IELT, OSAT, and PEP index score, and similar TEAEs, compared with that of dapoxetine only. Our results support the suggestion that the PDE5-Is have a potential role in the treatment of PE without ED.

OBJECTIVE: To determine the correlation between metabolic syndrome and the distribution of stone components in patients with urolithiasis. METHODS: Between January 2007 and December 2010, renal or ureteral stones were collected from 712 patients (432 males, 280 females) who underwent surgical intervention at three hospitals in South Korea. Metabolic syndrome was defined according to the latest definition of the International Diabetes Federation, using ethnicity- and sex-specific cut-off values for central obesity. Patients were assessed by factors used in metabolic syndrome. All urinary stones were analyzed using infrared spectrophotometry and categorized according to their main component. RESULTS: The patients' mean age was 55.9 years (range 19-93 years). Of the 712 patients, 347 (48.7%; 205 males, 142 females) had a diagnosis of metabolic syndrome. Calcium oxalate (71.5%), uric acid (15.3%), carbonate apatite (8.0%) and struvite (4.1%) calculi were found as the main stone components. Overall, the proportion of uric acid calculi was markedly higher in patients with rather than without metabolic syndrome (19.6 vs 11.2%; P=0.002). However, the proportion of calcium oxalate, carbonate apatite and struvite calculi did not differ between the two groups. The multivariable-adjusted odds ratio for uric acid calculi according to the metabolic syndrome components indicated that the presence of metabolic syndrome was associated with a 93% increased odds ratio of uric acid calculi compared with the absence of metabolic syndrome. Impaired fasting glucose and hypertriglyceridemia were independent risk factors for uric acid calculi. CONCLUSIONS: Metabolic syndrome is associated with a significantly increased risk of uric acid calculi development, especially those with impaired fasting glucose and hypertriglyceridemia.

PURPOSE: Prior research has indicated that stroke can influence the symptoms and presentation of neurogenic bladder, with various patterns emerging, including abnormal facial and linguistic characteristics. Language patterns, in particular, can be easily recognized. In this paper, we propose a platform that accurately analyzes the voices of stroke patients with neurogenic bladder, enabling early detection and prevention of the condition. METHODS: In this study, we developed an artificial intelligence-based speech analysis diagnostic system to assess the risk of stroke associated with neurogenic bladder disease in elderly individuals. The proposed method involves recording the voice of a stroke patient while they speak a specific sentence, analyzing it to extract unique feature data, and then offering a voice alarm service through a mobile application. The system processes and classifies abnormalities, and issues alarm events based on analyzed voice data. RESULTS: In order to assess the performance of the software, we first obtained the validation accuracy and training accuracy from the training data. Subsequently, we applied the analysis model by inputting both abnormal and normal data and tested the outcomes. The analysis model was evaluated by processing 30 abnormal data points and 30 normal data points in real time. The results demonstrated a high test accuracy of 98.7% for normal data and 99.6% for abnormal data. CONCLUSION: Patients with neurogenic bladder due to stroke experience long-term consequences, such as physical and cognitive impairments, even when they receive prompt medical attention and treatment. As chronic diseases become increasingly prevalent in our aging society, it is essential to investigate digital treatments for conditions like stroke that lead to significant sequelae. This artificial intelligence-based healthcare convergence medical device aims to provide patients with timely and safe medical care through mobile services, ultimately reducing national social costs.
RESUMEN
Globally, the population aged 65 years and over is growing faster than all other age groups. South Korea, in particular, is one of the most rapidly aging societies worldwide. With the increase in the older population, the incidence of urologic diseases has increased significantly along with that of chronic diseases. Urologic diseases are an important component of the health problems faced by an aging society. Among those, urinary incontinence and voiding dysfunction cause significant health and quality of life problems in older adults. To properly manage these diseases, especially in the field of urology, it is necessary to propose appropriate policies for the health care of older people. Accordingly, the significance of geriatrics, particularly geriatric urology, has increased. Although geriatric urology in South Korea began relatively recently, the founding of the Korean Society of Geriatric Urological Care represents a significant step in the development of geriatric urology as a subspecialty. The goal of this review is to elaborate on the concept of geriatrics and to provide an overview of geriatric urology with a focus on its current status in South Korea. Furthermore, future challenges in the face of rapid demographic changes are reviewed.
RESUMEN
OBJECTIVE: To analyze the diagnostic value of conducting urodynamic study (UDS) and show predictors for alpha blocker use 12 months after transurethral prostatectomy. MATERIALS AND METHODS: Our study includes 406 participants that had a transurethral prostatectomy at our hospital between 2010 and 2019. All participants took alpha blockers for more than a month. We collected the participants' preoperative international prostatic symptom score (IPSS), uroflowmetry, transrectal ultrasound, and serum prostatic antigen (PSA) level. A total of 254 patients conducted UDS. After surgery, participants visited our hospital at 1,3,6, and 12 months. RESULTS: 133 patients (32.6%) took alpha blockers continuously for 12 months after surgery. They reported poor preoperative IPSS scores and uroflowmetry outcomes. They also had high postoperative PVR (40.68±24.56 vs 29.34±25.11, p<0.001) and total IPSS score (10.35±7.96 vs 8.43±6.74, p = 0.018) compared to the group which discontinued alpha blockers. A multivariate analysis (Table 2) found that conducting preoperative UDS (Odds ratio (OR) 6.067, p<0.001) Age>75 (OR 2.463, p<0.001), a history of taking 5-alpha reductase inhibitors (5-ARI) before surgery (OR 2.186 [95% CI 1.334-3.583], p = 0.002), IPSS item straining (OR 1.224, p = 0.003), duration of taking alpha blockers [OR 1.009, p = 0.020), and Qmax (OR 0.926, p = 0.018), PVR (OR 1.002, p = 0.022) were confirmed as a strong predictors of persistent alpha blocker use. CONCLUSION: Conducting preoperative UDS, Age>75, history of taking 5-ARI before surgery, IPSS item straining, duration of alpha blocker medication, Qmax, and PVR are possible determinant factors of alpha blocker use after surgery. By comparing UDS outcomes, detrusor underactivity can be a strong predictor of persisting alpha blocker therapy 12 months after surgery.

PURPOSE: We investigated the relationship between nocturia and mortality risk in the United States. METHODS: Data were obtained from the National Health and Nutrition Examination Survey 2005-2010. Mortality data were obtained by linking the primary database to death certificate data found in the National Death Index with mortality follow-up up to December 31, 2015. Nocturia was defined based on symptoms reported in the symptom questionnaire. We categorized patients into 2 groups: mild nocturia (2-3 voids/night) and moderate-to severe nocturia (≥4 voids/night). Multiple Cox regression analyses were performed with adjustment for confounding variables at the baseline survey. RESULTS: This study included 9,892 adults (4,758 men, 5,134 women). Nocturia occurred in 3,314 individuals (33.5%). Nocturia was significantly associated with all-cause mortality (hazard ratio [HR], 1.23; 95% confidence interval [CI], 1.10-1.39) and cardiovascular disease (CVD) mortality (HR, 1.55; 95% CI, 1.19-2.01). Moreover, the mortality risk increased with increasing nocturia severity. Further analysis with propensity score matching showed that nocturia was still significantly associated with all-cause mortality and CVD mortality. In subgroup analysis according to sex, nocturia was significantly associated with allcause mortality and CVD mortality in men. In women, moderate-to-severe nocturia was significantly associated with allcause mortality and CVD mortality. In subgroup analysis according to cardio-metabolic diseases, nocturia was associated with CVD mortality in patients with diabetes mellitus, hypertension, dyslipidemia, or CVD at baseline. In subgroup analysis of patients without diabetes mellitus, hypertension or CVD, nocturia was significantly associated with all-cause mortality. CONCLUSION: Nocturia was significantly associated with mortality in men and women after adjusting for major confounding factors.
RESUMEN
BACKGROUND: Extrapyramidal signs (EPSs), which are important characteristics of Parkinson's disease (PD), occur frequently in Alzheimer's disease (AD). Although AD and PD share common clinical features such as EPSs, these diseases vary with respect to vascular risk factors. The presence of vascular risk factors increases the risk of AD; however, these factors have been known to be inversely associated with PD. We aimed to assess the effect of vascular risk factors and white matter lesions (WMLs) on EPSs in AD. METHODS: We recruited 1,187 AD patients and 333 controls with neither cognitive impairment nor EPSs. All participants underwent detailed clinical evaluations which included assessments of vascular risk factors, cognitive function, and EPSs, as well as WMLs on brain MRIs. EPS subtypes were classified into tremor-dominant, postural instability gait difficulty, or indeterminate; WMLs subtypes were classified into periventricular WML (pvWML) or deep WML (dWML). RESULTS: EPSs were present in 17.9% of subjects with AD and were significantly associated with vascular risk factors such as age, male gender, diabetes mellitus, and WMLs. Additionally, a multivariate logistic regression analysis showed that EPSs in AD were associated with pvWML (odds ratio (OR), 1.61-2.52), not with dWML. With respect to EPS subtypes, the majority (78.4%) of EPSs in AD were postural instability gait difficulty, which was also associated with WMLs (OR 1.84-2.41), pvWML (OR 2.09-3.14), and dWML (OR 1.83-3.42). CONCLUSIONS: EPSs in AD are associated with selected vascular risk factors as well as WMLs.

The pelvic floor consists of levator ani muscles including puborectalis, pubococcygeus and iliococcygeus muscles, and coccygeus muscles. Pelvic floor muscle exercise (PFME) is defined as exercise to improve pelvic floor muscle strength, power, endurance, relaxation, or a combination of these parameters. PFME strengthens the pelvic floor muscles to provide urethral support to prevent urine leakage and suppress urgency. This exercise has been recommended for urinary incontinence since first described by Kegel. When treating urinary incontinence, particularly stress urinary incontinence, PFME has been recommended as first-line treatment. This article provides clinical application of PFME as a behavioral therapy for urinary incontinence. Clinicians and physical therapist should understand pelvic floor muscle anatomy, evaluation, regimen, and instruct patients how to train the muscles properly.
