Awareness and prevalence of self-reported benign prostatic hyperplasia: a cross-sectional study in Saudi Arabia.

Background: Benign prostatic hyperplasia (BPH) is a prevalent condition in older men, causing significant morbidity. Despite recent progress, essential concerns of the disease remain under-researched. This study aims to assess knowledge and estimate self-reported prevalence of BPH in Saudi Arabian men. Understanding BPH prevalence in Saudi Arabia is essential for healthcare planning, resource allocation, public awareness, early detection, intervention, research, and addressing regional variations. Method: A cross-sectional study was conducted from February to May 2022 using a validated questionnaire. Univariate and multivariate statistical methods assessed knowledge of BPH among 559 adult Saudi men (mean age: 47.2 years) and its association with demographic variables. Results: The self-reported prevalence rate of BPH for Saudi Arabian men was 12.0%. Most adults (74.2%) were aware that BPH is a risk factor for prostate cancer and 75% were aware of the increased risk of BPH in older people. Furthermore, 44.5% of participants associated nocturia with BPH, while 76.6% related urinary tract infection (UTI) with BPH. The study demonstrated a significant association between BPH awareness and marital status (p = 0.02), level of education (p = 0.02), and employment status (p = 0.04). Conclusion: While men in Saudi Arabia generally had sufficient knowledge about BPH, there was a knowledge gap regarding certain risk factors like obesity and cardiac diseases. To address this, an educational program should be developed for both the general population and those at high risk of BPH.

Association between chronic prostatitis and the subsequent benign prostatic hyperplasia: a population-based national cohort study.

PURPOSE: To explore the association between chronic prostatitis (CP) and the subsequent development of benign prostatic hyperplasia (BPH). METHODS: Data analyzed were medical claims of Taiwan's National Health Insurance program. From 2010 to 2017, 3571 patients ≧20 years with CP diagnosed by certified urologists were enrolled. Patients with past BPH diagnosis and diagnosis of prostate cancer, inguinal hernia, interstitial cystitis, and urethritis in the past and within one year after the first CP diagnosis were excluded. Age-matched controls were randomly selected from all non-CP individuals of the same exclusion criteria in the study period with a CP/non-CP ratio of 1:4. The follow-up was made from the first CP diagnosis to death or the end of 2018. The endpoint was the newly diagnosed BPH. Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of BPH in association with CP. RESULTS: Over a maximum of 8 years of follow-up, 287 (8.03%) and 258 (0.43%) BPH events were noted for the CP and non-CP group, respectively, representing a covariate adjusted HR (aHR) of 4.30 (95% CI, 3.61-5.13). Younger patients tended to suffer from higher aHRs, especially those aged 20-39 years (aHR: 11.45, 95% CI, 5.12-25.64). CONCLUSION: The Taiwan national health database indicated that CP patients had a significantly higher risk of developing BPH later than non-CP patients. Interestingly, the younger the CP is diagnosed (under 40), the greater the risk.

Association between dietary phytochemical index and risk of benign prostatic hyperplasia: a case-control study.

BACKGROUND: Dietary intake of phytochemicals has been associated with a reduced risk of chronic diseases, but research on their relationship with benign prostatic hyperplasia (BPH) is limited. This case-control study aimed to investigate the association between a Dietary Phytochemical Index (DPI) and BPH risk in a Middle-Eastern population. METHODS: The study recruited 112 BPH patients and 112 age-matched healthy controls (40-75 years) from Al-Zahra Hospital Clinic in Isfahan, Iran between 2021 and 2022. Dietary intake was assessed using a validated food-frequency questionnaire, and DPI was calculated as the ratio of energy intake from phytochemical-rich foods to total daily energy intake. Logistic regression analysis was performed, adjusting for potential confounders. RESULTS: In the crude model, participants in the highest DPI tertile had a 70% lower odds of BPH compared to those in the lowest tertile (OR:0.3, 95% CI 0.15-0.61, P-trend = 0.001). After adjusting for confounders, this inverse association remained significant (OR:0.23, 95% CI 0.15-0.63, P-trend = 0.001). Participants with higher DPI consumed more whole grains (p = 0.02), nuts (p < 0.001), legumes (p = 0.02), fruits (p < 0.001), vegetables (p < 0.001), olives and oilve products (p = 0.02), and tomato and its products (p < 0.001) in their diet compared to the lowest tertile. However, red meat (p = 0.03) and refined grains (p < 0.001) were consumed in higher amounts in the lowest tertile compared to the highest DPI tertile. CONCLUSIONS: This study demonstrates a protective association between DPI and BPH risk in the Middle-Eastern population. Encouraging higher intake of phytochemical-rich foods may help reduce the risk of BPH, highlighting the relevance of nutritional science in promoting prostate health.

National Trends in Surgical Management for Benign Prostatic Hyperplasia From 2013 to 2019 in the United States.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a common urologic pathology for older men. The prevalence and effect on quality of life have prompted the development of new surgical procedures to manage BPH while attempting to minimize treatment side effects. The objective of this study is to utilize TriNetX, a third-party database, to investigate temporal trends in BPH procedures from 2013 to 2019 in the United States. METHODS: Male patients aged 18 to 100 who were diagnosed with BPH from 2013 to 2019 were filtered from the TriNetX Diamond Network. Yearly cohorts undergoing a BPH-related procedure were searched using Current Procedural Terminology and International Classification of Diseases 10th Revision codes. Temporal and descriptive analytics were utilized to describe trends in treatment utilization. RESULTS: There were 302,646 BPH procedures recorded on the TriNetX Diamond Network. Transurethral resection of the prostate was the most commonly performed procedure, accounting for 47.2% of procedures in 2013 and 44.9% in 2019. Photoselective vaporization of the prostate remained a popular treatment but showed the greatest decrease in utilization over time (31.8% in 2013, 21.5% in 2019). Prostatic urethral lift (UroLift) was rapidly embraced as a treatment modality, as usage increased by 18.3% over a 6-year period (0.0% in 2014, up to 18.3% in 2019). Other procedures such as Rezum (5.8%) and holmium laser enucleation of the prostate (5.1%) made up greater proportions of BPH procedures by 2019. CONCLUSIONS: Transurethral resection of the prostate was the most common procedure from 2013 to 2019. However, minimally invasive surgeries represent an increased percentage of BPH surgeries every year.

Benign Prostatic Hyperplasia and Incident Cardiovascular Disease.

BACKGROUND: Data regarding the relationship between benign prostatic hyperplasia (BPH) and incident cardiovascular disease (CVD) are scarce. We aimed to clarify the association of BPH with the risk of developing CVD using a nationwide epidemiological database.Methods and Results: This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 2,370,986 men (median age 44 years). The primary endpoints were myocardial infarction (MI), angina pectoris (AP), stroke, heart failure (HF), and atrial fibrillation (AF), which were assessed separately. BPH was observed in 48,651 (2.1%) men. During a mean (±SD) follow-up of 1,359±1,020 days, 7,638 MI, 52,167 AP, 25,355 stroke, 58,183 HF, and 16,693 AF events were detected. Hazard ratios of BPH for MI, AP, stroke, HF, and AF were 1.04 (95% confidence interval [CI] 0.92-1.18), 1.31 (95% CI 1.25-1.37), 1.26 (95% CI 1.18-1.33), 1.21 (95% CI 1.16-1.27), and 1.15 (95% CI 1.07-1.24), respectively. We confirmed the robustness of our primary findings through a multitude of sensitivity analyses. In particular, a history of BPH was associated with a higher risk of developing CVD, even in participants without obesity, hypertension, diabetes, or dyslipidemia. CONCLUSIONS: Our analysis of a nationwide epidemiological dataset demonstrated that BPH was associated with a greater risk of developing CVD in middle-aged men.

The epidemiology of male lower urinary tract symptoms associated with benign prostatic hyperplasia: Results of 20 years of Korean community care and surveys.

PURPOSE: To investigate the prevalence of lower urinary tract symptoms/benign prostatic hyperplasia in a Korean population. MATERIALS AND METHODS: The Korean Prostate & Voiding Health Association provided free prostate-related community health care and conducted surveys in all regions of Korea from 2001 to 2022 with the cooperation of local government public health centers. A total of 72,068 males older than 50 were surveyed and analyzed. History taking, International Prostate Symptom Score (IPSS), transrectal ultrasonography, prostate-specific antigen (PSA) testing, uroflowmetry, and urine volume testing were performed. RESULTS: The mean prostate volumes in males in their 50s, 60s, 70s, and 80s or above were 24.7 g, 27.7 g, 31 g, and 33.7 g, respectively. The proportion of males with high PSA greater than 3 ng/mL was 3.8% among males in their 50s, 7.7% among males in their 60s, 13.1% among males in their 70s, and 17.9% among males 80 years of age or older. The mean IPSS total scores in males in their 50s, 60s, 70s, and 80s or above were 10.7, 12.7, 14.5, and 16, respectively. Severe symptoms were reported by 27.3% of males, whereas 51.7% reported moderate symptoms. The mean Qmax in males in their 50s, 60s, 70s, and 80s or above were 20 mL/s, 17.4 mL/s, 15.4 mL/s, and 13.8 mL/s, respectively. CONCLUSIONS: In this population-based study, mean prostate volume, IPSS, PSA, and Qmax were 30.6±15.1 g, 14.8±8.2, 1.9±4.7 ng/mL, and 15.6±6.5 mL/s, respectively. Aging was significantly associated with increased prostate volume, PSA levels, and IPSS scores, and with decreased Qmax and urine volume.

The association between several serum micronutrients and benign prostatic hyperplasia: Results from NHANES 2003-2006.

BACKGROUND: Benign prostatic hyperplasia (BPH) is a common condition that affects the quality of life of older men. Specific micronutrients, including retinol, retinyl esters, carotenoids, vitamin E, and vitamin C, have antioxidant and anti-inflammatory properties. However, the correlation between serum concentrations of these micronutrients and BPH is unclear. METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES), which included 2067 representative US men. BPH was assessed using the self-reported questionnaire. This association was explored by adjusting for confounders using multivariate logistic regression. RESULTS: After fully adjusting for confounders, for every 0.01 µmol/L increase in serum retinyl esters, the risk of BPH increased by 2% (OR = 1.02; 95% CI: 1.01-1.03; p = 0.006). Based on the Bonferroni-corrected p-value, we found this correlation to be significant. One µmol/L increase in total carotenoids was associated with a 22% increase in BPH risk (OR = 1.22; 95% CI: 1.03-1.46; p = 0.025). By analyzing the correlation between different types of carotenoids and BPH, we also found that ß-carotenoids (OR = 1.43; 95% CI: 1.03-1.99; p = 0.036) was also positively correlated with BPH. The subgroup analysis revealed a positive correlation between serum vitamin E (OR = 1.02; 95% CI: 1.00-1.04; p = 0.018) and BPH in men under 60 years of age. Serum retinyl ester (OR = 1.02; 95% CI: 1.01-1.04; p = 0.008) and carotenoid (OR = 1.52; 95% CI: 1.22-1.87; p < 0.001) concentrations were positively correlated with BPH in men over 60 years of age. CONCLUSION: Our study suggests that excessive serum retinyl esters, total carotenoids, and especially ß-carotenoids are potential risk factors for BPH, and this association should be further investigated.

Incidence and risk factors of prostate cancer among the Northern and Eastern parts of the United Arab Emirates population.

BACKGROUND: Prostate cancer (PCa) is a prevalent disease worldwide. However, the incidence and patient-specific risk factors of PCa in the Middle East, specifically in the United Arab Emirates, have not been previously reported. METHODS: We conducted a retrospective cohort study on 2377 men diagnosed with either benign prostatic hyperplasia (BPH) or PCa in the Northern and Eastern regions of the United Arab Emirates, excluding the Western part, which includes Abu Dhabi. The study spanned from January 2012 and December 2021. To calculate the PCa incidence rate, we utilized the world age-standardized incidence rates (W-ASIR) categorized by age groups. Patient-specific risk factors of PCa were identified through a multivariate logistic regression analysis of clinical data. RESULTS: A total of 247 cases of PCa and 2130 cases of BPH were included in the study. In our cohort, the W-ASIR for PCa was 21.3 per 100,000 men. The incidence of PCa showed an increasing trend with age, with the highest incidence observed among men aged 70 years and older. Accordingly, multivariate analysis revealed that age over 70 was associated with an increased risk of PCa (OR: 2.546, 95% confidence interval [CI]: 1.892-3.425, p < 0.01). On the other hand, preexisting conditions such as hypertension and diabetes mellitus were found to lower the risk of PCa (OR: 0.222, 95% CI: 0.163-0.302, p < 0.001) and (OR: 0.364, 95% CI: 0.205-0.648, p < 0.001), respectively. Additionally, metformin intake was associated with a reduced risk of PCa (OR: 0.385, 95% CI: 0.190-0.782, p = 0.008); while insulin usage increased the risk of PCa (OR: 2.586, 95% CI: 1.539-4.344, p < 0.001). Anti-BPH medications such as phosphodiesterase inhibitors (OR: 0.223, 95% CI: 0.069-0.723, p = 0.012) or 5-α reductase (OR: 0.206, 95% CI: 0.110-0.389, p < 0.000), were found to lower the risk of PCa. CONCLUSION: The findings underscore the high incidence of PCa in the United Arab Emirates, with age being a significant factor. Furthermore, the study highlights the influence of certain comorbidities and medications on the risk of developing PCa within the United Arab Emirates population.

Cardiovascular Comorbidities Do Not Impact Prostate Artery Embolisation (PAE) Outcomes: Retrospective Analysis of the National UK-ROPE Registry.

PURPOSE: Prostate artery embolisation (PAE) is a key treatment for the management of symptomatic benign prostatic hyperplasia (BPH). Common cardiovascular risk factors might be associated with suboptimal outcomes and thus influence patient treatment selection. The aim of the study was to evaluate whether cardiovascular comorbidities affect PAE outcomes. METHODS: Retrospective subset analysis of the UK Registry of Prostate Artery Embolisation (UK-ROPE) database was performed with patients who had a full documented past medical histories including hypertension, diabetes, coronary artery disease (CAD), diabetes and smoking status as well as international prostate symptom score (IPSS) at baseline and at 12 months. Multiple regression was performed to assess for any significant predictors. RESULTS: Comorbidity data were available for 100/216 patients (mean age 65.8 ± 6.4 years), baseline IPSS 20.9 ± 7.0). Regression analysis revealed that the presence of hypertension (53.7% IPSS reduction vs. absence 51.4%, p = 0.94), diabetes (52.6% vs. absence 52.1%, p = 0.6), CAD (59.2% vs. absence 51.4%, p = 0.95), no comorbidities (49.8% vs. any comorbidity present 55.3%, p = 0.66), smoking status (non-smoker, 52.6%, current smoker, 61.5%, ex-smoker, 49.8%, p > 0.05), age (p = 0.52) and baseline Qmax (p = 0.41) did not significantly impact IPSS reduction at 12 months post-PAE. Baseline prostate volume significantly influenced IPSS reduction (≥ 80 cc prostates, 58.9% vs. < 80 cc prostates 43.2%, p < 0.05). CONCLUSION: The presence of cardiovascular comorbidities/smoking history does not appear to significantly impact PAE symptom score outcomes at 12 months post procedure. Our findings suggest that if the prostatic artery can be accessed, then clinical success is comparable to those without cardiovascular comorbidities.

[Herpes viruses and human papillomavirus in prostate cancer: first results].

INTRODUCTION: Benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are among the most common urological diseases in men. It has been repeatedly suggested that viral infection plays an important role in prostate carcinogenesis. AIM: To assess the relationship between viral infection and PCa, as well as the clinical and morphological features of BPH and PCa. MATERIALS AND METHODS: A total of 98 patients undergoing treatment for BPH (n=48) or PCa (n=50) between 2019 and 2021 were included in the study. Real-time PCR on the surgical specimens for human papillomaviruses (HPV), herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2), cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes virus type 6 (HSV-6) was performed. RESULTS: In patients with PCa, viruses in prostate tissue were found more often compared to those with BPH (50.0 vs. 31.3%, respectively, p=0.046.) The most common virus in both PCa and BPH was EBV (22.0 vs. 16.7%, respectively). The second most common virus in patients with PCa was HSV-6 (20.0%), which was not detected in any men with BPH (p=0.003). There was a trend toward higher prevalence of CMV among patients with PCa (16.0% vs. 4.2%), but the difference was not significant (p=0.09). There was no association of viral infection with clinical and morphological features. CONCLUSIONS: The resulting trend toward a higher prevalence of HSV-6 and CMV in patients with PCa compared to those with BPH creates the prerequisites for further study of viruses in prostate diseases involving a larger cohort, which will provide an idea of the multi-stage process of malignant transformation and, possibly, open new therapeutic options for prevention and treatment.

Prevalence and Distribution of Postvoid Residual Urine Volume in a Hospital-Based Sample of Men with Symptomatic Benign Prostatic Hyperplasia.

BACKGROUND: Benign prostatic hyperplasia (BPH) is a known cause of bladder outlet obstruction (BOO) in aging men. Patients present with lower urinary tract symptoms (LUTS), elevated postvoid residual urine (PVR), and reduced peak flow rate of urine. Although urodynamic study is the gold standard for diagnosing and quantifying BOO, it is invasive and as such urologists in their routine practice frequently rely on less invasive methods like PVR estimation to objectively assess BOO. AIM: To study the prevalence and distribution of PVR in a hospital-based population of men with symptomatic BPH. MATERIALS AND METHODS: Patients aged 40 years and above were enrolled for the study. History was taken from each of the 170 participants recruited, and physical examination was done including digital rectal examination. Every one of them completed the International Prostate Symptom Score (IPSS) questionnaire and also had ultrasonography assessment of PVR. Relevant laboratory investigations (PSA, renal function test, full blood count, urinalysis, and urine culture) and uroflowmetry to determine the peak flow rate of urine (Qmax) were done. RESULTS: A total of 170 subjects who met the inclusion criteria were enrolled for this study. The mean age of the subjects was 63.70 ± 9.92 years with a range of 42-88 years. The subjects had a mean PSA of 2.68 ± 0.91 ng/ml and a mean prostate volume of 70.8 ± 39.5 ml. The prevalence of significant PVR was 57.06%. The distribution of PVR was skewed with values ranging from 4.0 ml to 382.9 ml, a median value of 60.5 ml (interquartile range, IQR, =25.0-100.76), and a mean value of 77.70 ± 69.30 ml. An IPSS range of 8 to 23 with a mean value of 13.64 ± 4.14 and a median value of 13 (interquartile range = 10.0-16.0) was observed. The Qmax range was from 5 ml/s to 50 ml/s with a mean value of 20.25 ± 9.70 ml/s, and a median value of 18.0 ml/s (interquartile range = 14.0-24.0). CONCLUSION: This study showed that the prevalence of significant PVR volume among men with symptomatic BPH in our environment is high. There was also a high variation in the distribution of PVR among the subjects. Therefore, it is essential to create more public awareness especially among men in their fourth decade of life and above to visit a urologist whenever they have BPH symptoms so as to avoid impairment in quality of life and renal function associated with neglected significant PVR.

Benign prostatic hyperplasia and metabolic syndrome; prevalence and association: a cross-sectional study in Syria.

BACKGROUND: Benign Prostatic Hyperplasia (BPH) is considered the most common cause of lower urinary tract symptoms in men aged 40 years and older. BPH is related to sex steroids, but there are increasing studies investigating the relationship between the urinary symptoms and the metabolic syndrome. They still have inconsistent results; some reported a significant positive association, while others found no significant association. In this study, we aim to assess the prevalence rate of metabolic syndrome in BPH patients and whether there is an association between symptoms linked to BPH and metabolic syndrome in the Syrian community. METHODS: The participants of this observational cross-sectional study were benign prostatic hyperplasia patients aged 40-year-old and older from Homs, Syria. An interview questionnaire was performed to collect data from all patients who visited the urology clinic of Homs Military Hospital in the period of January 10 to March 10, 2023. We used the International Prostate Symptom Score (IPSS) to assess the urinary symptoms, and we used the US National Cholesterol Education Program Adult Treatment Panel (NCEP ATPIII) criteria to define the metabolic syndrome. RESULTS: The final sample size was 426 patients. The overall prevalence of metabolic syndrome was 46.2%. Patients with metabolic syndrome had higher International Prostate Symptom Score compared to patients without metabolic syndrome (21 vs. 18, P < 0.001), and 59.3% of patients with metabolic syndrome suffered from severe symptoms compared to 36.2% of patients without metabolic syndrome who suffered from severe lower urinary tract symptoms (P < 0.001). There was a positive association between (waist circumference, diabetes, triglycerides) (P < 0.001), HDL (P = 0.014) and higher International Prostate Symptom Score. However, there was no statistically significant association between blood pressure and International Prostate Symptom Score (P = 0.879). CONCLUSION: Our results showed that patients with metabolic syndrome had a higher International Prostate Symptom Score. This idea should be used to design a new benign prostatic hyperplasia/lower urinary tract symptoms treatment.

Cardiovascular Outcomes of α-Blockers vs 5-α Reductase Inhibitors for Benign Prostatic Hyperplasia.

Importance: The most prescribed class of medications for benign prostatic hyperplasia (BPH) is α-blockers (ABs). However, the cardiovascular safety profile of these medications among patients with BPH is not well understood. Objective: To compare the safety of ABs vs 5-α reductase inhibitors (5-ARIs) for risk of adverse cardiovascular outcomes. Design, Setting, and Participants: This active comparator, new-user cohort study was conducted using insurance claims data from a 20% random sample of Medicare beneficiaries from 2007 to 2019 to evaluate the 1-year risk of adverse cardiovascular outcomes. Males aged 66 to 90 years were indexed into the cohort at new use of an AB or 5-ARI. Twelve months of continuous enrollment and at least 1 diagnosis code for BPH within 12 months prior to initiation were required. Data were analyzed from January 2007 through December 2019. Exposures: Exposure was defined by a qualifying prescription fill for an AB or 5-ARI after at least 12 months without a prescription for these drug classes. Main Outcomes and Measures: Follow-up began at a qualified refill for the study drug. Primary study outcomes were hospitalization for heart failure (HF), composite major adverse cardiovascular events (MACE; hospitalization for stroke, myocardial infarction, or death), composite MACE or hospitalization for HF, and death. Inverse probability of treatment and censoring-weighted 1-year risks, risk ratios (RRs), and risk differences (RDs) were estimated for each outcome. Results: Among 189 868 older adult males, there were 163 829 patients initiating ABs (mean [SD] age, 74.6 [6.2] years; 579 American Indian or Alaska Native [0.4%], 5890 Asian or Pacific Islander [3.6%], 9179 Black [5.6%], 10 610 Hispanic [6.5%], and 133 510 non-Hispanic White [81.5%]) and 26 039 patients initiating 5-ARIs (mean [SD] age, 75.3 [6.4] years; 76 American Indian or Alaska Native [0.3%], 827 Asian or Pacific Islander [3.2%], 1339 Black [5.1%], 1656 Hispanic [6.4%], and 21 605 non-Hispanic White [83.0%]). ABs compared with 5-ARIs were associated with an increased 1-year risk of MACE (8.95% [95% CI, 8.81%-9.09%] vs 8.32% [95% CI, 7.92%-8.72%]; RR = 1.08 [95% CI, 1.02-1.13]; RD per 1000 individuals = 6.26 [95% CI, 2.15-10.37]), composite MACE and HF (RR = 1.07; [95% CI, 1.03-1.12]; RD per 1000 individuals = 7.40 [95% CI, 2.88-11.93 ]), and death (RR = 1.07; [95% CI, 1.01-1.14]; RD per 1000 individuals = 3.85 [95% CI, 0.40-7.29]). There was no difference in risk for HF hospitalization alone. Conclusions and Relevance: These results suggest that ABs may be associated with an increased risk of adverse cardiovascular outcomes compared with 5-ARIs. If replicated with more detailed confounder data, these results may have important public health implications given these medications' widespread use.

Clinical signs associated with prostatic disorders in canines: Retrospective study in Uruguay (2011-2019).

Background: Prostate disease represents about 0.7% of diseases in canines. The main diagnosed pathology is benign prostatic hyperplasia (BPH). However, the reports that study the association of a certain clinical sign with a specific prostate disease are scarce. Aim: The main objective of this study was to evaluate the clinical relevance of the most commonly observed clinical signs associated with the different prostatic disorders in canines admitted to the hospital of the Facultad de Veterinaria-Universidad de la República between 2011 and 2019. Methods: This retrospective study included 7,729 male canines treated at the hospital de la Facultad de Veterinaria-Universidad de la República (Montevideo, Uruguay) between 2011 and 2019. 289 canines with a presumptive/definitive diagnosis of prostate diseases were selected, recording the presence/absence of associated clinical signs. Results were reported in terms of odds ratios (ORs) using logistic regression (p < 0.05). Results: The five most frequently reported clinical signs were tenesmus (34%), anorexia (32%), lethargy (27%), prostatomegaly or pain during rectal examination (25%), and abdominal pain from palpation (22%). Diarrhea (3.39 vs. 0.33 OR), anorexia (2.07 vs. 0.39 OR), weight loss (2.27 vs. 0.27 OR), hematuria (3.25 vs. 0.44 OR), and urinary incontinence (2.96 vs. 0.33 OR) indicated a highest predictive value (p < 0.05) with prostatitis versus BPH, respectively. Being weight loss, the clinical sign is more frequently associated with neoplasia (20.2 OR, p = 0.002). Conclusion: This study shows that there are clinical signs with a higher degree of association for certain canine prostatic disorders than others.

The relationship between depression and benign prostatic hyperplasia in middle-aged and elderly men in India: a large-scale population study.

BACKGROUND: There have been few investigations on the association between depression and benign prostatic hyperplasia (BPH). This study aims to explore the correlation between depression and BPH among middle-aged and older men in India. METHODS: We utilized data from male individuals aged 45 years and older who participated in the initial wave (2017-2018) of the Longitudinal Aging Study in India (LASI). The presence of BPH symptoms was based on self-reported information, while depressive symptoms were evaluated using CESD-10. The analysis was a cross-sectional study conducted on a final sample size of 30,108 male participants. To examine associations, we employed multivariate logistic regression analysis along with subgroup analysis and interaction tests. RESULTS: A total of 439 (1.46%) men reported BPH and had a higher depression score (10.18 ± 4.22 vs. 9.28 ± 4.00). The findings indicated a significant association between the depression score and the likelihood of developing BPH, even after accounting for all potential confounding variables (OR = 1.054, 95% CI: 1.030-1.078, p < 0.00001). The participants were then categorized into a depression group and a normal group based on their CESD-10 score, using a threshold of 10 to ascertain the existence or nonexistence of depression. After adjusting for all variables in model IV, the findings continued to exhibit statistical significance (OR = 1.611, CI: 1.327-1.955, p < 0.00001). Significant interaction effects of age, education level, caste or tribe, and alcohol consumption were observed (p for interaction < 0.05). CONCLUSION: Our research found that BPH was significantly linked to the presence of depressive symptoms among middle-aged and elderly Indian men. Additional prospective research is necessary to clarify this association and investigate potential mechanisms.

Association of serum uric acid levels with benign prostatic hyperplasia in US men: results from NHANES 2005-2008.

BACKGROUND: The relationship between uric acid (UA) and benign prostatic hyperplasia (BPH) is controversial and has rarely been studied in American populations. METHODS: Data from two cycles of the National Health and Nutrition Examination Surveys, comprising data from 2005 to 2008, were used. The majority of BPH were identified by self-report. We investigated the relationship between UA and BPH using univariate and multivariate logistic regression analyses. RESULTS: 2,845 participants were enrolled in the study, including 531 participants with BPH and 2,314 controls. After fully adjusting for all confounders, the risk of developing BPH was reduced by 18% for every 100 µmol/L increase in UA (OR = 0.82, 95% CI: 0.69-0.97, p = 0.023). Participants in the highest quartile of UA were found to have a reduced likelihood of developing BPH (ORQ4vs1 = 0.61, 95% CI: 0.41-0.91) in comparison to those in the lowest quartile of UA. Subgroup analyses found that among those younger than 60 years, non-Hispanic whites, former smokers, heavy drinkers, those without diabetes, or those with hypertension, high UA remained negatively associated with BPH. CONCLUSIONS: The above results suggest that UA may be a potential protective factor for BPH, but the mechanism needs to be further explored.

SARS-CoV-2 infection correlates with male benign prostatic hyperplasia deterioration.

INTRODUCTION: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) affects extra-respiratory systems, with small-scale studies showing worsened male lower urinary tract symptoms (LUTS) after coronavirus disease 2019 (COVID-19). This study explores the correlation between SARS-CoV-2 infection and male benign prostatic hyperplasia (BPH) complications using large-scale real world data. MATERIALS AND METHODS: All male patients attending the public healthcare system in Hong Kong receiving alpha-blocker monotherapy for LUTS from 2021 to 2022 were included in this study. Patients with and without positive polymerase chain reaction (PCR) test for SARS-CoV-2 are selected as the exposure group and control group, respectively. Baseline characteristics are retrieved, with propensity score matching performed to ensure balance of covariates between the two groups. BPH complications were then compared and subgroup analyses were performed. RESULTS: After propensity score matching, 17,986 patients were included for analysis, among which half had PCR-confirmed SARS-CoV-2 infection (n = 8993). When compared to controls, the SARS-CoV-2 group demonstrated statistically significant higher incidence of retention of urine (4.55% vs. 0.86%, p < 0.001), haematuria (1.36% vs. 0.41%, p < 0.001), clinical urinary tract infection (UTI) (4.31% vs. 1.49%, p < 0.001), culture-proven bacteriuria (9.02% vs. 1.97%, p < 0.001) and addition of 5ARI (0.50% vs. 0.02%, p < 0.001). Subgroup analysis demonstrated similar differences across different age groups. There are no statistically significance differences in incidence of retention, haematuria, or addition of 5ARI across different COVID-19 severities. CONCLUSIONS: SARS-CoV-2 infection is associated with increased incidence of urinary retention, haematuria, UTI and the addition of combination therapy in the short term, regardless of COVID-19 severity. This is the largest study demonstrating the detrimental urological effects of SARS-CoV-2 infection.
