Peyronie's disease development and management in diabetic men

Background: Peyronie's disease (PD) is a fibrosing disorder of the penis resulting in plaque formation and penile deformity that negatively affect sexual and psychosocial function of patients. A multifactorial etiology of PD is assumed with diabetes mellitus (DM) being a potential risk factor. Objectives: The aim of this narrative review was to investigate diabetes role in PD pathophysiology, diagnosis, and treatment. Materials and methods: A non-systematic narrative review of original articles, meta-analyses, and randomized trials was conducted, including articles in the pre-clinical setting to support relevant findings. Results: Diabetes is one of the most common comorbidity observed in PD patients, with a prevalence of about 11% and a strong association with erectile dysfunction (ED). DM is associated with both a higher risk of developing PD and has also an impact on the outcomes of PD's treatments. Discussion: Evidence from literature underlines that metabolic alterations typical of DM are pivotal factors in the development of PD and resistance to its medical treatment. Conclusion: The role of DM in development of PD is still debated, while its role in PD development is not completely clear, there is a clear impact of DM on PD treatment outcomes

Clinical correlation among male infertility and overall male health: a systematic review of the literature

Purpose: Ongoing evidence has suggested the role of male factor infertility as a potential predictor of mortality and general health status. The aim of the present review is to update the current knowledge base regarding the association between male factor infertility and general health through a critical review of the literature. Materials and Methods: A systematic review of the literature was carried out from inception to November 2019 in order to evaluate significant associations between male infertility and adverse health outcomes such as cardiovascular, oncologic, metabolic and autoimmune diseases as well as overall mortality. Results: In all, 27 studies met inclusion criteria and were critically examined. Five studies examined male infertility and cardiovascular disease risk, 11 examined oncologic risk (e.g., overall cancer risk, testis and prostate cancer), 8 examined aggregate chronic medical diseases and 5 infertility related to incidence of mortality, for a total of 599,807 men diagnosed with any male factor infertility covering a period from 1916 to 2016. Conclusions: A man’s fertility and overall health appear to be interconnected. Therefore, a diagnosis of male infertility may allow a window into future comorbidity and/or mortality which may help guide clinical decisions and counseling. Several possible etiologies such as genetic, epigenetic, developmental, and lifestyle-based factors need to be further evaluated in order to establish the underlying mechanisms between male infertility and health

The association of impaired semen quality and pregnancy rates in assisted reproduction technology cycles: Systematic review and meta-analysis

Some studies suggest a relationship between semen quality and pregnancy rates of assisted reproduction technologies (ART). Others have questioned the utility of semen quality as proxy for fertility in couples attempting to conceive with or without assistance. We aimed to investigate the current body of evidence which correlates semen parameters and clinical pregnancy among couples utilizing ART (i.e. in vitro fertilization [IVF], intracytoplasmic sperm injection [ICSI]) through a systematic review and meta-analysis of cross-sectional and retrospective cohort studies. Pooled Odd Ratio (OR) for oligo-, astheno- and teratospermic compared to normospermic number of ART cycles were calculated among. Meta-regression and sub-group analysis were implemented to model the contribution of clinical/demographic and laboratory standards differences among the studies. Overall, 17 studies were analysed representing 17,348 cycles were analysed. Pooled OR for impaired sperm concentration, motility and morphology was 1 (95%Confidence Interval [CI]: 0.97-1.03), 0.88 (95%CI: 0.73-1.03) and 0.88 (95%CI: 0.75-1) respectively. Further analysis on sperm morphology showed no differences with regard of IVF versus ICSI (p = 0.14) nor a significant correlation with rising reference thresholds (Coeff: -0.02, p = 0.38). A temporal trend towards a null association between semen parameters and clinical pregnancy was observed over the 20-year observation period (Coeff: 0.01, p = 0.014). The current analysis found no association between semen quality (as measured by concentration, motility or morphology) and clinical pregnancy rates utilizing ART. Future investigations are necessary to explore the association between semen parameters and other ART outcomes (e.g. fertilization, implantation, birth and perinatal health)

SHBG levels in primary infertile men : A critical interpretation in clinical practice

Objective: We aimed to test the association between age, BMI and sex-hormone\u2013binding globulin (SHBG) in a homogenous cohort of white-European men presenting for primary couple\u2019s infertility. Design: Retrospective study. Methods: Data from 1547 infertile men were analysed. Health-significant comorbidities were scored with the Charlson comorbidity index (CCI). Fasting serum hormones were measured in every patient. Age was considered according to quartile groups (<33, 33-41, >41 years) and BMI as normal weight (18.5\u201324.9 kg/m2), overweight (25.0\u201329.9 kg/m2) and obesity (>30 kg/m2). Descriptive statistics and linear regression analysis tested the associations between age, BMI and SHBG. Results: Median SHBG levels increased across quartiles of age and decreased along with BMI increases (all P < 0.001). For each year increase in age, SHBG increased 0.32 nmol/L; conversely, for each unit increase in BMI, SHBG decreased by 1.1 nmol/L (all P < 0.001). SHBG levels decline with increasing BMI was greater than SHBG progressive increase with age. Overall, BMI explained 3.0 times more of the variability in SHBG than did ageing. At multivariate linear model, age and BMI were the most significant factors influencing SHBG concentration (all P < 0.001), after accounting for CCI, albumin levels and smoking status. Conclusions: We found a wide distribution of SHBG concentrations across age and BMI values in primary infertile men. The association between BMI and lowered SHBG levels seems to be greater than the association of ageing with increased SHBG

Recent Trends in the Diagnostic and Surgical Management of Benign Prostatic Hyperplasia in the U.S. from 2004 to 2017: Annual Changes in the Selection of Treatment Options and Medical Costs

Background: Transurethral resection of the prostate (TURP) is the gold-standard treatment for benign prostatic hyperplasia (BPH). However, laser surgery techniques (e.g., photoselective vaporization of the prostate (PVP), holmium laser, thulium laser enucleation of the prostate (HoLEP or ThuLEP)), and minimally invasive treatment options (e.g., UroLift) are increasingly replacing TURP. This study seeks to report the annual incidence, management trends, and costs of BPH procedures in the U.S. Methods: Data analyses of U.S. health insurance claims from 2004 to 2017, collected from the de-identified Optum Clinformatics Claims Database, were performed to determine the number of BPH patients and the treatment selected. Results: A total of 51,448 patients underwent BPH procedures from 2004 to 2017. There was a significant increase in the annual rate from 770 in 2004 to 6571 in 2017. The mean patient age (±SD) increased from 67.6 years old (±8.4) in 2004 to 73.4 years old (±8.4) in 2017. More than 60% of patients underwent cystourethroscopy and a post-void residual urine check for workup prior to surgical management. TURP was the most-common, and PVP was the second-most-common BPH procedure. Medical and total treatment costs increased, while the detection rate of prostate cancer after BPH surgery gradually decreased from 19.87% in 2004 to 5.78% in 2017. Conclusions: Our study demonstrates a recent trend in BPH management that replaces the traditional TURP technique with alternative methods. Due to rising costs, future studies should assess whether these newer methods are cost effective over the long ter

Characteristics of Sepsis or Acute Pyelonephritis Combined with Ureteral Stone in the United States: A Retrospective Analysis of Large National Cohort

To identify the characteristics of patients with sepsis or acute pyelonephritis (APN) combined with ureteral calculi and to analyze the risk factors in its causation. Methods: We included patients with sepsis or APN caused by ureteral calculi who received treatment in the United States from January 2003 to December 2017 using the Optum® deidentified Clinformatics® Datamart. Demographic factors and risk factors for the receipt of sepsis or APN were subsequently analyzed for statistical significance. Results: Of 467,502 urinary stone patients, age-matched multivariate analysis revealed that a history of urinary tract infection (OR 11.31, 95% CI 10.68–11.99, p < 0.0001) and female gender (OR 2.73, 95% CI 2.62–2.84, p < 0.0001) were significantly related to an increased risk of sepsis or APN. Conversely, a previous past medical history of urolithiasis (OR 0.91, 95% CI 0.87–0.95, p < 0.0001) and cancer (OR 0.91, 95% CI 0.87–0.95, p < 0.0001) were associated with a decreased risk of sepsis or APN. With regards to comorbidities, when more than one comorbidity was present, there was an additive effect with higher OR point estimates, rising to 11.31 (10.68–11.99) when three or more comorbidities present. History of urinary tract infection and female gender are risk factors for sepsis or APN in patients with ureteral calculi. Conclusions: This large national cohort reveals the characteristics of sepsis or APN combined with ureteral stone and provides an important baseline for the treatment of urolithiasis in the future

Male fertility as a marker for health

Male reproduction is a complex biological process, and male factor infertility is increasingly recognized as a biomarker for overall male health. Emerging data suggest associations between male reproduction and medical disease (genetic, infectious, chronic comorbid conditions), psychological disease, environmental exposures, dietary habits, medications and substances of abuse, and even socioeconomic factors. There is also evidence that a diagnosis of male fertility is associated with future disease risk including cancer, metabolic disease and mortality. As such, there is a growing view that the male fertility evaluation is an opportunity to improve a man's health beyond his immediate reproductive goals, and also highlights the necessity of a multidisciplinary approach

The association between testosterone, estradiol and their ratio and mortality among US men

While studies have suggested that testosterone is associated with a man's health, the relationship with other sex steroids remains uncertain. The current study aimed to investigate the association between sex steroids (i.e. testosterone, estradiol and the testosterone:estradiol ratio) and mortality in a representative sample of 1,109 US men. Three NHANES continuous cycles (1999–2000, 2001–2002, 2003–2004) were included in our study. Serum testosterone and estradiol levels were evaluated along with sociodemographic, lifestyle and health factors. Cox proportional hazards models were used. The adjusted risk of death for men with low testosterone levels was 1.66 (95% CI&nbsp;=&nbsp;1.00–2.74, p&nbsp;=.05). The adjusted risk of death for men with abnormal estradiol levels was 0.96 (95% CI&nbsp;=&nbsp;0.48–1.91, p&nbsp;=.91). The adjusted risk of death for men with low testosterone to estradiol ratio was 1.27 (95% CI&nbsp;=&nbsp;0.82–1.97, p&nbsp;=.88). Relevant lifestyle and health factors significantly attenuated the associations. The adjusted risk of CVD-related death for men with low testosterone levels was 2.43 (95% CI&nbsp;=&nbsp;1.07–5.50, p&nbsp;=.03). In conclusion, a significant association between testosterone and mortality and testosterone to estradiol ratio and CVD-related mortality was identified

Long-Term Follow-Up After Penile Prosthesis Implantation\u2014Survival and Quality of Life Outcomes

Introduction: Hydraulic penile prostheses have shown an overall good mechanical reliability up to 10 years after surgery; however, few data have been published on very long-term follow-up. Aim: We looked at long-term ( 6515 years) complications, including functional and quality of life (QoL) outcomes, after 3-piece inflatable penile prosthesis (IPP) implantation in patients with erectile dysfunction (ED). Methods: Data regarding 149 patients submitting to IPP placement before 2001 were analyzed. All patients were implanted with AMS CX and Ultrex Plus 3-piece prostheses. Main Outcome Measure: Patients were reassessed to evaluate rates of complications and functional outcomes. The validated questionnaire Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) was used to assess patient QoL. Kaplan-Meier analysis estimated the probability of prosthesis survival (defined as working device/not-explanted). Results: Median follow-up of 51 patients was 206 months (interquartile range [IQR], 145\u2013257). The etiology of ED was vasculogenic (n = 20; 39%), Peyronie's disease (n = 15; 29%), pelvic surgery (n = 4; 7.8%), organic other than vasculogenic (n = 3; 5.9%), or other (n = 9; 18%). Throughout the follow-up, 24 patients (49%) experienced complications: mechanical failure (n = 19; 79%), pain (n = 3; 12%), orgasmic dysfunctions (n = 1; 4.5%), or device infection (n = 1; 4.5%). The estimated IPP survival was 53% (95% CI, 36\u201367) at 20-year follow-up. Baseline characteristics (age, Charlson comorbidity index, body mass index, and erectile dysfunction etiology) were not significantly associated with the risk of IPP failure over time by Cox regression analysis. At 20-year follow-up, 41% (95% CI, 19\u201349) of the patients were still using the device. Among them, QoLSPP median domain scores were high: functional 22/25 (IQR, 20\u201323), relational 17/20 (IQR, 15\u201318), personal 14/15 (IQR, 12\u201315), and social 14/15 (IQR, 11\u201315). Clinical Implications: The longevity of the device and long-term satisfaction rates should be comprehensively discussed during patient consultation for IPP surgery. Strengths &amp; Limitations: To our knowledge, this is the first study reporting long-term QoL outcomes using a dedicated questionnaire for penile prostheses. The low response rate for the telephone interviews, the retrospective design of the study, and the relatively small number of patients are the main limitations. Conclusion: Long-term follow-up data after IPP placement showed that almost half of the devices still worked properly 20 years after the original penile implant, as 60% of patients were still using the device with high satisfaction and adequate QoL outcomes. Both patients and physicians should be aware of the expected life and outcomes of IPP implants. Chierigo F, Capogrosso P, Deh\uf2, et al.
