Prevalence and predictors of female sexual dysfunction among sexually active women in the diabetes prevention program outcomes study.

OBJECTIVE: To determine the burden and identify correlates of female sexual dysfunction (FSD) among women with prediabetes (PreD) and type 2 diabetes (T2D) enrolled in the Diabetes Prevention Program (DPP) Outcomes Study (DPPOS). METHODS: The DPPOS visit included the Female Sexual Function Index (FSFI) to determine sexual function. Of 1464 participants, 1320 (90%) completed the (FSFI) and 426 were sexually active. A backward selection multivariable logistic regression model estimated the odds of FSD for sociodemographic, clinical, and diabetes-related covariates. RESULTS: One hundred and eighty-five (43%) had a score of ≤26.55 and met the criteria for FSD. After adjustment for DPP treatment and age, urinary incontinence (UI) (odds ratio [OR] = 1.91, 95% confidence interval [CI] = 1.15-3.17) and hysterectomy (OR = 1.89, 95% CI = 1.01-3.53) were associated with increased odds of FSD. Increased body mass index was protective for FSD (OR = 0.93 per kg/m2, 95% CI = 0.89-0.96). Michigan Neuropathy Screening Instrument-based peripheral neuropathy (mean±SD scores 1.1±1.3 vs. 0.9±1.1, p < 0.0001) and Electrocardiogram (ECG)-based autonomic dysfunction measures (mean ± SD heart rate levels 64.3 ± 6.8 vs. 65.6 ± 10.2, p = 0.008) were associated with FSD. There were no differences in diabetes rates between women who did (66.5%) and did not (66%) have (p = 0.7). CONCLUSIONS: FSD is prevalent in women with PreD and T2D. Our findings suggest that FSD is associated with neuropathic complications commonly observed in PreD and T2D.

Patient and physician decision-making dynamics in overactive bladder care: A mixed methods study.

AIMS: Overactive bladder management includes multiple therapeutic options with comparable efficacy but a range of administration modalities and side effects, creating an ideal setting for shared decision-making. This study investigates patient and physician health beliefs surrounding decision-making and expectations for overactive bladder with the aim of better understanding and ultimately improving decision-making in overactive bladder care. METHODS: Patient and physician participants completed a questionnaire followed by a semi-structured interview to assess health beliefs surrounding decision making and expectations for overactive bladder treatment. The semi-structured interview guide, developed in an iterative fashion by the authors, probed qualities of overactive bladder therapies patients and physicians valued, their process of treatment selection, and their experiences with therapies. RESULTS: Patients (n = 20) frequently cited treatment invasiveness, efficacy, and safety as the most important qualities that influenced their decision when selecting overactive bladder therapy. Physicians (n = 12) frequently cited safety/contraindications, convenience, cost/insurance, and patient preference as the most important qualities. In our integration analysis, we identified four key themes associated with decision making in overactive bladder care: frustration with inaccessibility of overactive bladder treatments, discordant perception of patient education, diverging acceptability of expected outcomes, and lack of insight into other parties' decisional priorities and control preferences. CONCLUSIONS: While both patients and physicians desire to engage in a shared decision-making process when selecting therapies for overactive bladder, this process is challenged by significant divergence between patient and physician viewpoint across key domains.

Urinary symptoms and female sexual dysfunction in women with type 1 diabetes: the role of depression.

BACKGROUND: Some reports suggest that women with type 1 diabetes (T1D) have a greater burden of female sexual dysfunction (FSD) than women without T1D, but the etiology of this elevated risk is poorly understood. AIM: To examine the associations between FSD and urinary incontinence/lower urinary tract symptoms (UI/LUTS) in women with T1D and to evaluate how depression may mediate these relationships. METHODS: LUTS and UI symptoms were assessed in women with T1D who participated in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study. Multivariable logistic regression models estimated associations between FSD and UI/LUTS (overall and specific domains) and the impact of depression on these associations. OUTCOMES: FSD was measured with the Female Sexual Function Index-Reduced. RESULTS: In total, 499 self-reported sexually active women completed validated assessments of sexual and urinary function (mean ± SD age, 47.7 ± 7.6 years; T1D duration, 23.4 ± 5.15 years). FSD was reported in 232 (46%) responders. The frequency of UI and LUTS was 125 (25.1%) and 96 (19.2%), respectively. Neither UI nor its subcategories (urge, stress) were associated with FSD. Although LUTS (odds ratio [OR], 1.75; 95% CI, 1.09-2.77) and its symptoms of urgency (OR, 1.99; 95% CI, 1.09-3.61) and incomplete emptying (OR, 2.44; 95% CI, 1.23-4.85) were associated with FSD, these associations were attenuated following adjustment for depression and antidepressant medication use. Depression indicators were independently associated with FSD overall and across domains. CLINICAL IMPLICATIONS: The complex interplay of voiding dysfunction, mental health, and sexual function warrants further investigation to understand the potential implications for patient assessment, goal setting, treatment, and care planning. STRENGTHS AND LIMITATIONS: Data are from a prospective study of individuals with T1D. These results are unable to explore cause-and-effect relationships among LUTS, UI, depression, and FSD. The sample may not be representative of the general population of women with T1D. Because participants in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study are mostly White, generalizing the findings to other races and to type 2 diabetes may not be appropriate. While exclusion of sexually inactive women likely biases our findings toward the null, this design element permitted study of LUTS and UI in relation to aspects of FSD, the primary objective of this study. CONCLUSIONS: The significant associations between LUTS/UI and FSD among middle-aged women with T1D were greatly attenuated when depression was considered a mediating factor.

What Is a Normal Testosterone Level for Young Men? Rethinking the 300 ng/dL Cutoff for Testosterone Deficiency in Men 20-44 Years Old.

PURPOSE: There is an age-related decline in male testosterone production. It is therefore surprising that young men are evaluated for testosterone deficiency with the same cutoff of 300 ng/dL that was developed from samples of older men. Our aim is to describe normative total testosterone levels and age-specific cutoffs for low testosterone levels in men 20 to 44 years old. MATERIALS AND METHODS: We analyzed the 2011-2016 National Health and Nutrition Examination Surveys, which survey nationally representative samples of United States residents. Men 20 to 44 years old with testosterone levels were included. Men on hormonal medications, with a history of testicular cancer or orchiectomy, and with afternoon/evening laboratory values were excluded. We separated men into 5-year intervals and evaluated the testosterone levels of each age group, and for all men 20 to 44 years old. We used the American Urological Association definition of a "normal testosterone level" (the "middle tertile") to calculate age-specific cutoffs for low testosterone levels. RESULTS: Our final analytic cohort contained 1,486 men. Age-specific middle tertile levels were 409-558 ng/dL (20-24 years old), 413-575 ng/dL (25-29 years old), 359-498 ng/dL (30-34 years old), 352-478 ng/dL (35-39 years old), and 350-473 ng/dL (40-44 years old). Age-specific cutoffs for low testosterone levels were 409, 413, 359, 352, and 350 ng/dL, respectively. CONCLUSIONS: Diagnosis of testosterone deficiency has traditionally been performed in an age-indiscriminate manner. However, young men have different testosterone reference ranges than older men. Accordingly, age-specific normative values and cutoffs should be integrated into the evaluation of young men presenting with testosterone deficiency.

Impact of Sleep Disturbance, Physical Function, Depression and Anxiety on Male Lower Urinary Tract Symptoms: Results from the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN).

PURPOSE: The impact of nonurological factors on male lower urinary tract symptoms (LUTS) remains unclear. We investigated cross-sectional and longitudinal associations among anxiety, depression, physical function, sleep quality and urinary symptom subdomains. MATERIALS AND METHODS: Data from 518 men in the LURN (Symptoms of Lower Urinary Tract Dysfunction Research Network) study were analyzed to identify associations between Patient-Reported Outcomes Measurement Information System® (PROMIS®) depression, anxiety, sleep disturbance and physical function measures and LUTS subdomains, as derived from the American Urological Association Symptom Index and LUTS Tool. Multivariable linear regression was used to assess the relationships between PROMIS measures and LUTS subdomains at baseline and at 3- and 12-month followup. RESULTS: Baseline depression and anxiety were associated with urinary incontinence (p <0.001), voiding symptoms (p <0.001) and quality of life (p=0.002), whereas baseline sleep disturbance was associated with voiding and storage symptoms and quality of life (p <0.001 for all). Urinary symptom severity improved in all subdomains at 3 and 12 months. Similar associations between PROMIS measures and LUTS subdomains were observed at all time points, but baseline depression, anxiety, sleep disturbance and physical function measures were not associated with longitudinal trajectories of LUTS. CONCLUSIONS: Urinary symptom subdomains are independently associated with modifiable clinical variables including sleep quality and depression at all time points, but these variables do not predict the degree of improvement in LUTS following urological evaluation and treatment over the medium term. Bidirectional assessment and randomized experiments may improve our understanding of these relationships.

Longitudinal patterns of urinary incontinence and associated predictors in women with type 1 diabetes.

AIMS: Urinary incontinence (UI) in women is a dynamic condition with numerous risk factors yet most studies have focused on examining its prevalence at a single time. The objective of this study was to describe the long-term time course of UI in women with type 1 diabetes (T1D). METHODS: Longitudinal data in women with T1D were collected from 568 women in the Epidemiology of Diabetes Interventions and Complications (EDIC) study, the observational follow-up of the Diabetes Control and Complications Trial (DCCT) cohort. Over a 12-year period, participants annually responded to whether they had experienced UI in the past year. RESULTS: We identified four categories of UI in this population over time: 205 (36.1%) women never reported UI (no UI), 70 (12.3%) reported it one or two consecutive years only (isolated UI), 247 (43.5%) periodically changed status between UI and no UI (intermittent UI), and 46 (8.1%) reported UI continuously after the first report (persistent UI). Compared to women reporting no/isolated UI, women displaying the intermittent phenotype were significantly more likely to be obese (OR: 1.86, 95% CI 1.15, 3.00) and report prior hysterectomy (OR: 2.57, 95% CI: 1.39, 4.77); whereas women with persistent UI were significantly more likely to have abnormal autonomic function (OR: 2.36, 95% CI: 1.16-4.80). CONCLUSIONS: UI is a dynamic condition in women with T1D. Varying risk factors observed for the different phenotypes of UI suggest distinctive pathophysiological mechanisms. These findings have the potential to be used to guide individualized interventions for UI in women with diabetes.

Trends in Procedures to Initiate Renal Replacement Therapy among People Living with Spina Bifida.

PURPOSE: Given the increasing prevalence of chronic kidney disease in people with spina bifida, we sought to determine if this is associated with an increase in end stage kidney disease. We examined population based data to measure the frequency of procedures to establish renal replacement therapy-a marker for end stage kidney disease-among patients with spina bifida. MATERIALS AND METHODS: We used the Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery and Services Database from Florida, Kentucky, Maryland and New York (2000 to 2014), which include encounter level data. With a diagnosis code based algorithm we identified all procedural encounters made by patients with spina bifida. We determined the percentage of these encounters that were for facilitating renal replacement therapy (ie arteriovenous anastomosis, renal transplantation). We assessed for changes over time in this percentage with the Cochran-Armitage trend test. Bivariate analysis was performed using chi-square test. RESULTS: Of all procedures performed on patients with spina bifida over this time the proportion of procedures performed to establish renal replacement therapy significantly decreased in both the inpatient and outpatient settings (p=0.042 and p <0.001, respectively). People with spina bifida undergoing procedures to establish renal replacement therapy were, on average, young adults (mean age 34.5 and 36.0 years) with a high prevalence hypertension (75.8% of inpatients, 68.6% of outpatients). CONCLUSIONS: The frequency of surgeries to initiate renal replacement therapy among people with spina bifida undergoing procedures is low and is not increasing. This highlights the importance of consistent care throughout adolescence and young adulthood, and hypertension screening.

Relationship of symptom severity and bother in individuals seeking care for lower urinary tract symptoms.

AIMS: Bother attributed to lower urinary tract symptoms (LUTS) drives care-seeking and treatment aggressiveness. The longitudinal relationship of LUTS severity and bother in a care-seeking cohort, however, is not well understood. We aim to conduct a longitudinal evaluation of LUTS severity and bother and identify characteristics of patients with discordant LUTS bother relative to severity. METHODS: Men and women with LUTS seeking care at six US tertiary care centers enrolled in the symptoms of lower urinary tract dysfunction research network study. Patients reporting at least one urinary symptom based on the LUTS Tool were prospectively enrolled from June 2015 to January 2017. Correlations were used to assess the relationship between LUTS severity and bother. Discordance scores (ie, the difference between bother and severity) were used to classify patients with high and low bother. Patients were classified as having high or low bother phenotypes if scores were one standard deviation above or below zero, respectively. Repeated measures multinomial logistic regression evaluated characteristics associated with high and low bother phenotypes. RESULTS: LUTS severity and bother were at least moderately correlated for all symptom items and highly correlated for 13 out of 21 items. Correlations were highest for urgency, and lowest for daytime frequency and urinary incontinence. Odds of being in high bother phenotype were lowest at 3 and 12 months (3 months vs baseline odds ratio [OR] = 0.71, 95% confidence ninterval [CI] = 0.54-0.94; 12 months vs baseline OR = 0.66, 95% CI = 0.48-0.91), and highest for those who endorsed all urgency questions (OR = 3.65, 95% CI = 2.17-6.13). Odds of being in the low bother phenotype were lowest for patients who endorsed all urgency items (OR = 0.33, 95% CI = 0.26-0.42), and all frequency items (OR = 0.68, 95% CI = 0.53-0.88). CONCLUSIONS: LUTS severity and bother correlate highly and measurement of both in clinical practice is likely redundant. There are patient factors associated with discordance which may justify additional evaluation.

Longitudinal Patterns of Occurrence and Remission of Erectile Dysfunction in Men With Type 1 Diabetes.

BACKGROUND: Men with diabetes are at greater risk of erectile dysfunction (ED). AIM: To describe the natural history of ED in men with type 1 diabetes. METHODS: We examined up to 30 years of prospectively collected annual ED status and demographic and clinical variables from 600 male participants in the Diabetes Control and Complications Trial (DCCT; 1983-1993) and its follow-up study, the Epidemiology of Diabetes Interventions and Complications (1994-present; data in this study are through 2012). OUTCOMES: Yes vs no response to whether the participant had experienced impotence in the past year and whether he had used ED medication. RESULTS: Sixty-one percent of men reported ED at least once during the study. For some men, the initial report of ED was permanent. For others, potency returned and was lost multiple times. Visual display of the data showed four longitudinal ED phenotypes: never (38.7%), isolated (6.7%), intermittent (41.8%), and persistent (12.8%). Men who never reported ED or in only 1 isolated year were younger, had lower body mass index, and better glycemic control than men in the intermittent and persistent groups at DCCT baseline. In a multivariable logistic model comparing men at their first year reporting ED, men who were older had lower odds of remission and men who were in the conventional DCCT treatment group had higher odds of remission. CLINICAL TRANSLATION: If validated in other cohorts, such findings could be used to guide individualized interventions for patients with ED. STRENGTHS AND LIMITATIONS: This is the first examination of ED with repeated measures at an annual resolution, with up to 30 years of responses for each participant. However, the yes vs no response is a limitation because the real phenotype is not binary and the question can be interpreted differently depending on the participant. CONCLUSIONS: Age, glycemic control, and BMI were important longitudinal predictors of ED. We have described a more complex ED phenotype, with variation in remission patterns, which could offer insight into different mechanisms or opportunities for intervention. If validated in other cohorts, such findings could be used to establish more accurate prognostication of outcomes for patients with ED to guide individualized interventions.

Glycemic Control and Urinary Tract Infections in Women with Type 1 Diabetes: Results from the DCCT/EDIC.

PURPOSE: We examined the relationship between glycemic control and urinary tract infections in women with type 1 diabetes mellitus. MATERIALS AND METHODS: Women enrolled in the Epidemiology of Diabetes Interventions and Complications study, the observational followup of the Diabetes Control and Complications Trial, were surveyed to assess the rate of physician diagnosed urinary tract infections in the preceding 12 months. The relationship between glycated hemoglobin levels and number of urinary tract infections in the previous 12 months was assessed using a multivariable Poisson regression model. RESULTS: A total of 572 women were evaluated at year 17. Mean age was 50.7 ± 7.2 years, mean body mass index was 28.6 ± 5.9 kg/m(2), mean type 1 diabetes duration was 29.8 ± 5.0 years and mean glycated hemoglobin was 8.0% ± 0.9%. Of these women 86 (15.0%) reported at least 1 physician diagnosed urinary tract infection during the last 12 months. Higher glycated hemoglobin levels were significantly associated with number of urinary tract infections such that for every unit increase (1%) in recent glycated hemoglobin level, there was a 21% (p=0.02) increase in urinary tract infection frequency in the previous 12 months after adjusting for race, hysterectomy status, urinary incontinence, sexual activity in the last 12 months, peripheral and autonomic neuropathy, and nephropathy. CONCLUSIONS: The frequency of urinary tract infections increases with poor glycemic control in women with type 1 diabetes. This relationship is independent of other well described predictors of urinary tract infections and suggests that factors directly related to glycemic control may influence the risk of lower urinary tract infections.

Testosterone and cardiac mass and function in men with type 1 diabetes in the Epidemiology of Diabetes Interventions and Complications Study (EDIC).

OBJECTIVE: Low testosterone concentrations have been reported to be associated with increased risk of congestive heart failure, but the mechanisms are unclear. Our objective was to examine the relationship between endogenous testosterone and measures of cardiac mass and function among men with type 1 diabetes. DESIGN: Secondary analysis of a prospective observational study. PARTICIPANTS: Men (n = 508) in the Epidemiology of Diabetes Interventions and Complications (EDIC) study, the observational follow-up of the Diabetes Control and Complications Trial (DCCT). MEASUREMENTS: Testosterone assessed by liquid chromatography mass spectrometry at EDIC year 10 and cardiac magnetic resonance imaging (CMR) measures at EDIC years 14/15. Linear regression models were used to assess the relationship between testosterone, sex hormone binding globulin (SHBG) and left ventricular (LV) mass, volume, ejection fraction and cardiac index before and after adjustment for age, randomization arm, alcohol and cigarette use, macroalbuminuria, haemoglobin A1c, insulin dose, body mass index, lipids, blood pressure, use of antihypertensive medications and microvascular complications. RESULTS: In fully adjusted models, total testosterone concentrations were significantly associated with LV mass (P = 0·014), end-diastolic volume (P = 0·002), end-systolic volume (P = 0·012) and stroke volume (P = 0·022), but not measures of LV function after adjustment for cardiac risk factors. Bioavailable testosterone was associated with LV mass, but not volume or function, while SHBG was associated with volume, but not mass or function. CONCLUSIONS: Among men with type 1 diabetes, higher total testosterone was associated with higher LV mass and volume, but not with function. The clinical significance of this association remains to be established.

Urogenital Autonomic Dysfunction in Diabetes.

This review details the epidemiology, possible mechanisms, and risk factors associated with urogenital autonomic dysfunction in diabetes. Autonomic neuropathy in diabetes is associated with various urological complications including bladder and sexual dysfunction. Several studies have reported the high prevalence of bladder and sexual dysfunction in both men and women. The DCCT/EDIC UroEDIC study examined the association between cardiovascular autonomic neuropathy and bladder and sexual dysfunction in a large cohort of participants with type 1 diabetes and was the first to report significant associations. Future studies are needed to further evaluate the association of urogenital complications and autonomic dysfunction in diabetes.

Cardiovascular autonomic neuropathy, erectile dysfunction and lower urinary tract symptoms in men with type 1 diabetes: findings from the DCCT/EDIC.

PURPOSE: We evaluated the association between cardiovascular autonomic neuropathy, and erectile dysfunction and lower urinary tract symptoms in men with type 1 diabetes. MATERIALS AND METHODS: Male type 1 diabetes participants (635) in the DCCT/EDIC were studied. Cardiovascular autonomic neuropathy was assessed by standardized cardiovascular reflex tests including changes in respiratory rate variation with deep breathing, Valsalva maneuver (Valsalva ratio) and changes in supine to standing diastolic blood pressure. Erectile dysfunction was assessed by a proxy item from the International Index of Erectile Function, and lower urinary tract symptoms were assessed with the AUASI (American Urological Association Symptom Index). Multivariable logistic regression models estimated the association between cardiovascular autonomic neuropathy and erectile dysfunction and/or lower urinary tract symptoms, adjusting for time weighted glycemic control, blood pressure, age and other covariates. RESULTS: Men in whom erectile dysfunction and/or lower urinary tract symptoms developed during EDIC had a significantly lower respiratory rate variation and Valsalva ratio at DCCT closeout and EDIC year 16/17 compared to those without erectile dysfunction or lower urinary tract symptoms. In adjusted analysis, participants with cardiovascular autonomic neuropathy had 2.65 greater odds of erectile dysfunction and lower urinary tract symptoms (95% CI 1.47-4.79). CONCLUSIONS: These data suggest that cardiovascular autonomic neuropathy predicts the development of urological complications in men with long-standing type 1 diabetes. Studies evaluating the mechanisms contributing to these interactions are warranted for targeting effective prevention or treatment.

Poor glycemic control is associated with reduced prostate specific antigen concentrations in men with type 1 diabetes.

PURPOSE: Previous studies have revealed lower prostate specific antigen concentrations in men with type 2 diabetes, paralleling the reported lower prevalence of prostate cancer in diabetic men. Data are lacking on prostate specific antigen in men with type 1 diabetes whose insulin and obesity profiles differ from those with type 2 diabetes mellitus. In this study we examined the relationship between long-term glycemic control and prostate specific antigen in men with type 1 diabetes mellitus. MATERIALS AND METHODS: Total prostate specific antigen was measured at one time in 639 men in the EDIC, the observational followup of participants in the DCCT. The relationship between DCCT/EDIC weighted mean hemoglobin A1c and log prostate specific antigen was assessed using linear regression modeling after adjusting for age, body mass index, total testosterone, statin and thiazide medication use, diabetes duration, and DCCT randomization arm and cohort. RESULTS: Median subject age was 52 years, body mass index was 28.4 kg/m(2) and DCCT/EDIC time-weighted hemoglobin A1c was 7.9%. Median prostate specific antigen was 0.64 ng/ml (IQR 0.43, 1.05). Prostate specific antigen increased significantly with age (p <0.0001) and with lower time-weighted hemoglobin A1c (p <0.0001). Each 10% increase in hemoglobin A1c was accompanied by an 11% reduction in prostate specific antigen (p=0.0001). CONCLUSIONS: Prostate specific antigen decreases as hemoglobin A1c increases in men with type 1 diabetes mellitus. This relationship is independent of age, body mass index, androgen levels, medication use and measures of diabetes severity, which suggests that factors related to glycemia may directly affect prostate specific antigen levels.

Testosterone Concentrations and Cardiovascular Autonomic Neuropathy in Men with Type 1 Diabetes in the Epidemiology of Diabetes Interventions and Complications Study (EDIC).

INTRODUCTION: Previous studies have reported that lower testosterone concentrations are associated with cardiovascular autonomic neuropathy (CAN), a risk factor for cardiovascular events. However, no studies have examined this relationship in men with type 1 diabetes, who are at high risk for CAN. AIM: The aim of this study was to examine the associations between testosterone concentrations and measures of CAN in a large, well-characterized cohort of men with type 1 diabetes. METHODS: We conducted an analysis of men in the Diabetes Control and Complications Trial (DCCT), a randomized trial of intensive glucose control, and its observational follow-up the Epidemiology of Diabetes Intervention and Complications (EDIC) Study. Testosterone was measured by liquid chromatography mass spectrometry in stored samples from EDIC follow-up years 10 and 17. Regression models were used to assess the cross-sectional relationships between testosterone and CAN measures. MAIN OUTCOME MEASURES: The main CAN measure from EDIC follow-up year 17 was a standardized composite of R-R variation with paced breathing < 15, or R-R variation 15-20 combined with either a Valsalva ratio ≤ 1.5 or a decrease in diastolic blood pressure > 10 mm Hg upon standing. Continuous R-R variation and Valsalva ratio were secondary outcomes. RESULTS: Lower total and bioavailable testosterone concentrations at follow-up years 10 and 17 were not associated with the presence of CAN at year 17. In analyses using Valsalva ratio as a continuous measure, higher total (P = 0.01) and bioavailable testosterone concentrations (P = 0.005) were associated with a higher (more favorable) Valsalva ratio after adjustment for covariates including age, body mass index, smoking status, hypertension, and glycemia. CONCLUSIONS: Testosterone levels are not associated with CAN among men with type 1 diabetes. Although testosterone is associated with a higher Valsalva ratio, a more favorable indicator, the clinical significance of this association is not known.

Hyperglycemia and insulin resistance and the risk of BPH/LUTS: an update of recent literature.

Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are highly prevalent in older men and represent a substantial challenge to public health. Increasing epidemiologic evidence suggests that diabetes and associated hyperglycemia and insulin resistance significantly increase the risks of BPH and LUTS. Plausible pathophysiologic mechanisms to explain these associations include increased sympathetic tone, stimulation of prostate growth by insulin and related trophic factors, alterations in sex steroid hormone expression, and induction of systemic inflammation and oxidative stress. This article presents a comprehensive update of the current understanding of clinical and epidemiologic research on diabetes and BPH/LUTS, describes hypothesized pathophysiologic mechanisms linking these conditions, and recommends future directions for research.

Disparities in the Delivery of Prostate Cancer Survivorship Care in the USA: A Claims-based Analysis of Urinary Adverse Events and Erectile Dysfunction Among Prostate Cancer Survivors.

Background and objective: Incidence rates for prostate cancer (PCa) diagnosis and mortality are higher for Black men. It is unknown whether similar disparities exist in survivorship care. We assessed the delivery and quality of survivorship care for Black men undergoing PCa therapy in terms of the burden of and treatment for urinary adverse events (UAEs) and erectile dysfunction (ED). Methods: We queried Optum Clinformatics data for all patients diagnosed with PCa from January 1, 2002 to December 31, 2017 and identified those who underwent primary PCa treatment. Index cohorts were identified in each year and followed longitudinally until 2017. Data for UAE diagnoses, UAE treatments, and ED treatments were analyzed in index cohorts. Cox proportional-hazards regression models were used to examine associations of race with UAE diagnosis, UAE treatment, and ED treatment. Key findings and limitations: We identified 146, 216 patients with a PCa diagnosis during the study period, of whom 55, 149 underwent primary PCa treatment. In the primary treatment group, 32.7% developed a UAE and 28.2% underwent UAE treatment. The most common UAEs were urinary incontinence (11%), ureteral obstruction/stricture (4.5%), bladder neck contracture (4.5%), and urethral stricture (3.7%). The most common UAE treatments were cystoscopy (13%), suprapubic tube placement (6%), and urethral dilation (5%). Overall, UAE diagnosis rates were higher for Black patients, who had significantly higher risk of urethral obstruction, rectourethral fistula, urinary incontinence, cystitis, urinary obstruction, and ureteral fistula. Overall, UAE treatment rates were lower for Black patients, who had significantly higher risk of fecal diversion and/or rectourethral fistula repair (adjusted hazard ratio [aHR] 1.71, 95% confidence interval [CI] 1.04-2.79). Regarding ED treatments, Black patients had higher risk of penile prosthesis placement (aHR 1.591, 95% CI 1.26-2.00) and intracavernosal injection (aHR 1.215, 95% CI 1.08-1.37). Conclusions and clinical implications: Despite a high UAE burden, treatment rates were low in a cohort with health insurance. Black patients had a higher UAE burden and lower UAE treatment rates. Multilevel interventions are needed to address this stark disparity. ED treatment rates were higher for Black patients. Patient summary: We reviewed data for patients treated for prostate cancer (PCa) and found that 32.7% were diagnosed with a urinary adverse event (UAE) following their PCa treatment. The overall treatment rate for these UAEs was 28.2%. Analysis by race showed that the UAE diagnosis rate was higher for Black patients, who were also more likely to receive treatment for erectile dysfunction.

Poor Glycemic Control Increases Dental Risk in a Sri Lankan Population.

Introduction: The aim of our study was to investigate the impact of diabetes-related factors on the dental disease outcomes of diabetes patients in Trincomalee, Sri Lanka. Materials and Methods: Dental data were collected from 80 type-2-diabetic individuals. A dental risk score was calculated based on the frequency of dental outcomes observed and categorized as low risk (≤3 dental outcomes) and high risk (>3 dental outcomes). Results: In this cohort of men and women with type 2 diabetes, there was a high frequency of periodontal related outcomes, including missing teeth (70%), gingival recessions (40%), tooth mobility (41%), and bleeding (20%). Thirty-nine (39%) of participants had high dental risk, while forty-nine (61%) had low risk. Conclusions: After controlling for age, participants with higher capillary blood glucose levels had 3-fold greater odds of a high dental risk score (OR = 2.93, 95%CI = 1.13, 7.61). We found that poor glycemic control indicated by elevated capillary blood glucose was associated with increased dental risk.

Uptake of Same-Day Discharge for Patients Undergoing Robot-Assisted Radical Prostatectomy in the Michigan Urological Surgery Improvement Collaborative.

PURPOSE: Postoperative length of stay (LOS) after robot-assisted radical prostatectomy (RARP) is a potentially modifiable aspect of prostate cancer care. Our objective was to evaluate the use of same-day discharge (SDD) RARP and compare pre- and perioperative characteristics of these men with those who underwent hospitalization postoperatively. MATERIALS AND METHODS: Perioperative outcomes for patients undergoing RARP were evaluated from the Michigan Urological Surgery Improvement Collaborative (MUSIC) registry. Men were classified by hospital LOS: SDD, 1 day, and 2 days. Practice and surgeon-level variation of SDD and the change in SDD use over time were assessed. The primary outcome was 30-day readmission after RARP. RESULTS: We identified 10,249 men undergoing RARP in MUSIC from 2018 to 2022. Most patients had 1-day LOS (79.6%), with 2.8% undergoing SDD. The proportion of patients undergoing RARPs with SDD rose from 0.6% in 2018 to 1.2% in 2019 and 4.4% for 2020 to 2022. At least one SDD was performed in 12 of 28 MUSIC practices (42.9%) and by 52 of 138 urologists (37.7%). In multivariable analysis, odds of 30-day readmission were not significantly different between patients undergoing SDD and LOS 1 day (OR: 1.72, 95% CI: 0.92-3.22, P = .090). Limitations include retrospective, registry-based observational study with nonuniform utilization of SDD. CONCLUSIONS: Although more patients have undergone SDD after RARP beginning in 2018, rates across Michigan have remained < 5% annually. Importantly, patients undergoing SDD RARP did not experience significantly more readmissions compared to hospitalized patients. SDD appears safe and feasible for select patients who are motivated by this approach.
