UNASSIGNED: The relationship between cathepsins and prostate cancer (PCa) has been reported. However, there is a lack of research on cathepsins and benign prostate diseases (BPDs). This study investigated the potential genetic link between cathepsins and BPDs through the utilization of Mendelian randomization (MR) analysis to determine if a causal relationship exists.
UNASSIGNED: Publicly accessible summary statistics on BPDs were obtained from FinnGen Biobank. The data comprised 149,363 individuals, with 30,066 cases and 119,297 controls for BPH, and 123,057 individuals, with 3,760 cases and 119,297 controls for prostatitis. The IEU OpenGWAS provided the Genome-wide association data on ten cathepsins. To evaluate the causal relationship between BPDs and cathepsins, five distinct MR analyses were employed, with the primary method being the inverse variance weighted (IVW) approach. Additionally, sensitivity analyses were conducted to examine the horizontal pleiotropy and heterogeneity of the findings.
UNASSIGNED: The examination of IVW MR findings showed that cathepsin O had a beneficial effect on BPH (IVW OR=0.94, 95% CI 0.89-0.98, P=0.0055), while cathepsin X posed a threat to prostatitis (IVW OR=1.08, 95% CI 1.00-1.16, P=0.047). Through reverse MR analysis, it was revealed that prostatitis had an adverse impact on cathepsin V (IVW OR=0.89, 95% CI 0.80-0.99, P=0.035), while no favorable association was observed between BPH and cathepsins. The results obtained from MR-Egger, weighted median, simple mode, and weighted mode methods were consistent with the findings of the IVW approach. Based on sensitivity analyses, heterogeneity, and horizontal pleiotropy are unlikely to distort the results.
UNASSIGNED: This study offers the initial evidence of a genetic causal link between cathepsins and BPDs. Our findings revealed that cathepsin O was beneficial in preventing BPH, whereas cathepsin X posed a potential threat to prostatitis. Additionally, prostatitis negatively affected cathepsin V level. These three cathepsins could be targets of diagnosis and treatment for BPDs, which need further research.

UNASSIGNED: Benign prostatic hyperplasia (BPH) is the most common benign disease causing voiding dysfunction in middle-aged and elderly men. the current \"gold standard\" for surgical treatment is transurethral resection of the prostate (TURP). Continuous bladder irrigation (CBI) is routinely given for 3 to 5 days after operation. However, this may induce bladder spasm. Bladder spasm not only brings physical and mental pain to patients, delaying the postoperative recovery process, but it also increases the medical economic burden. Therefore, it is important to take active measures to effectively warn and deal with bladder spasm. The color of the drainage fluid is an important indicator and requires close observation during CBI, as it can reflect real-time postoperative bleeding. When the color of drainage fluid is abnormal, effective measures should be undertaken. Grading nursing intervention divides patients into different conditions according to their possible changes, and then recommends targeted nursing intervention. Existing studies have formulated CBI programs from the perspective of quantifying the relationship between drainage fluid color and irrigation speed, but have yet to incorporate bladder spasm prevention and control levels or design corresponding grading nursing intervention programs according to different drainage fluid colors. This study aimed to construct the risk warning classification and intervention plan of bladder spasm under the guidance of CBI speed adjusting card after TURP.
UNASSIGNED: Based on the rate adjustment card of CBI after TURP, we formulated the first draft of an early warning classification of risk in bladder spasm and its intervention plans by combining methods suggested from a literature search with semi-structured interviews and results from 2 rounds of correspondence inquiries with 28 experts by the Delphi method. We further screened and revised grading standards and measures.
UNASSIGNED: The positive coefficients of experts in 2 rounds of correspondence inquiries were both 100%, the authority coefficients were both 0.952, and the Kendall harmony coefficients were 0.238 and 0.326, respectively (P<0.01). In the second round of correspondence inquiries, the coefficient of variation of expert opinions was 0.000-0.154, and the coefficient of variation of all items was <0.25. Finally, a 3-level risk warning classification standard and 23 nursing measures for CBI complicated by bladder spasm was constructed.
UNASSIGNED: The early warning classification of risk in bladder spasm and its intervention plans guided by rate adjustment card of CBI after TURP are scientific and feasible, and can provide a basis and guidance for effective and standardized CBI in patients after TURP.

OBJECTIVE: To evaluate the efficacy and safety of using Androgel in men with endogenous testosterone deficiency and lower urinary tract symptoms (LUTS), associated with benign prostatic hyperplasia (BPH) in routine clinical practice.
METHODS: The multicenter, prospective, comparative study \"POTOK\" included 500 patients aged over 50 years with biochemical signs of testosterone deficiency (morning total testosterone concentration <12.1 nmol/l) and LUTS/BPH (International Prostatic Symptoms Score [IPSS] score of 8-19). The recruitment and monitoring of patients was carried out in 2022 in 40 clinics in Russia. Depending on the therapy, all patients were divided into two groups. The physician\'s decision to prescribe a specific drug (according to the approved patient information leaflet), as well as the subsequent follow-up scheme and therapy, was made a priori and independently of patient. In the first group (n=250) alpha-blockers and Androgel were prescribed, while in the second group (n=250) patients received monotherapy with alpha-blockers. The follow-up duration was 6 months. The efficiency of the therapy was evaluated after 3 and 6 months according to IPSS, symptoms of androgen deficiency (AMS and IIEF scores), uroflowmetry (peak flow rate, total urination volume), ultrasound study (postvoid residual and prostate volume). Safety was assessed by the total number of adverse events, stratified by severity and frequency. Statistical analysis was carried out using IBM SPSS 26.0.
RESULTS: According to the primary end-point (IPSS score), there were significant differences between groups 1 and 2 after 3 months (11 vs. 12 points, p=0.009) and 6 months of therapy (9 vs. 11 points, p<0.001). There were also significant differences in the severity of symptoms of androgen deficiency after 3 and 6 months of therapy according to AMS score of 35 vs. 38 points (p<0.001) and 28 vs. 36 points (p<0.001), respectively. According to IIEF, all domains (erectile and orgasmic functions, libido, sexual satisfaction with and general satisfaction) were better in group 1 (p<0.001). After 6 months, uroflowmetry values also differed. In group 1 Qmax was 16 ml/s compared to 15.2 ml/s in group 2 (p=0.004); postvoid residual was 10 ml vs. 15.5 ml, respectively (p=0.001). The prostate volume in group 1 after 6 months of treatment was significantly lower (39.5 cc) compared with group 2 (43.3 cc; p=0.002). During the study, 18 mild AEs, 2 moderate AEs, and 1 severe AE were identified without significant differences between the groups (p>0.05).
CONCLUSIONS: The results of study \"POTOK\" showed greater efficacy and comparable safety of alpha-blockers in combination with Androgel compared with monotherapy with alpha-blockers in men with LUTS/BPH and endogenous testosterone deficiency in routine clinical practice. The increase in serum testosterone concentrations to normal values in patients with age-related hypogonadism favorably influence on the severity of LUTS and the potentiate the effect of the standard monotherapy with alpha-blockers.

UNASSIGNED: This study explores the risk of diabetes-associated lower and upper urinary tract diseases among male older adults aged 45 and above in India.
UNASSIGNED: Longitudinal Ageing Study in India (LASI), 2017-2018 data was used in this study. The prevalence of various urinary tract problems and diabetes among male older adults was estimated by background characteristics using bivariate cross-tabulation. In addition, multivariate logistic regression was applied to examine the likelihood of urological disorders associated with diabetes.
UNASSIGNED: The prevalence of incontinence was highest among male older adults with diabetes, followed by kidney stones, benign prostatic hyperplasia, and chronic renal failure. Multivariate logistic regression estimation showed that men diagnosed with diabetes were 80% more likely to experience chronic renal failure, 78% more likely to suffer from incontinence, and 37% more likely to suffer from kidney stones than those without diabetes when controlling for various socio-demographic, behavioral, and co-morbidity status of the older adults.
UNASSIGNED: The study findings suggest that diabetes is associated with multiple urinary complications among male older adults in India and needs more careful investigation of the phenomenon. Independent risk factors such as changes in lifestyle with regular monitoring and diagnosis may help to prevent the progression of diabetes and reduce the risk of diabetes-associated lower and upper urinary tract diseases among male older adults.

UNASSIGNED: Due to its anti-oxidative effects, bilirubin may protect against a spectrum of diseases. However, the role of bilirubin in patients with benign prostatic hyperplasia (BPH) is poorly explored. This study aimed to investigate the cross-sectional associations between serum indirect bilirubin (IBIL) and prostate volume (PV) in patients with BPH.
UNASSIGNED: The medical records of 722 BPH patients were retrospectively analyzed. Body mass index (BMI) was calculated as body weight (kg)/height (m)2. PV was obtained as height (cm) × width (cm) × length (cm) × π/6. Other biochemical indexes were measured by the automatic biochemical analyzer. A univariable linear regression analysis was performed to detect confounders. The IBIL-PV relationship was examined using unadjusted and covariate-adjusted regression models. Furthermore, a segmented linear regression was conducted to analyze the linear trend of IBIL levels and PV. Finally, the sensitivity analysis was stratified by BMI and low-density lipoprotein cholesterol (LDL-C) cutoffs.
UNASSIGNED: In this study, the mean age of the patients was 68 (range, 43-93) years. By univariable line regression test, we observed that PV was positively correlated with age, BMI, and LDL-C (β=0.113, 0.096, and 0.135, respectively). IBIL was negatively associated with PV in full adjusted model in men age ≤75 years (β=-1.01; 95% CI: -1.81, -0.22; P=0.01). A statistically significant inverse trend was observed between serum IBIL intervals and PV in patients aged ≤75 years (adjusted for age, BMI, and LDL-C, P for trend =0.015). In sensitivity analysis, significantly negative IBIL-PV relationship only existed in men with normal BMI (adjusted β=-1.328; 95% CI: -2.467, -0.190; P=0.022), overweight men (adjusted β=-1.296; 95% CI: -2.519, -0.074; P=0.038), and men with normal LDL-C level (adjusted β=-1.017; 95% CI: -1.869, -0.164; P=0.019).
UNASSIGNED: IBIL is negatively associated with PV in the non-obese population ≤75 years with normal LDL-C. These results suggest that higher serum IBIL possibly provides a degree of protection to BPH by mitigating oxidative stress (OS) related to aging and lipid peroxidation. Nevertheless, these preliminary findings from a single-center, retrospective study have limitations and need to be confirmed by future studies.

Obesity (waist circumference, body mass index (BMI)) and lifestyle factors (dietary habits, smoking, alcohol drinking, Sedentary behavior) have been associated with risk of benign prostatic hyperplasia (BPH) in observational studies, but whether these associations are causal is unclear.
We performed a univariable and multivariable Mendelian randomization study to evaluate these associations. Genetic instruments associated with exposures at the genome-wide significance level (P < 5 × 10-8) were selected from corresponding genome-wide associations studies (n = 216,590 to 1,232,091 individuals). Summary-level data for BPH were obtained from the UK Biobank (14,126 cases and 169,762 non-cases) and FinnGen consortium (13,118 cases and 72,799 non-cases). Results from UK Biobank and FinnGen consortium were combined using fixed-effect meta-analysis.
The combined odds ratios (ORs) of BPH were 1.24 (95% confidence interval (CI), 1.07-1.43, P = 0.0045), 1.08 (95% CI 1.01-1.17, P = 0.0175), 0.94 (95% CI 0.67-1.30, P = 0.6891), 1.29 (95% CI 0.88-1.89, P = 0.1922), 1.23 (95% CI 0.85-1.78, P = 0.2623), and 1.04 (95% CI 0.76-1.42, P = 0.8165) for one standard deviation (SD) increase in waist circumference, BMI, and relative carbohydrate, fat, protein and sugar intake, 1.05 (95% CI 0.92-1.20, P = 0.4581) for one SD increase in prevalence of smoking initiation, 1.10 (95% CI 0.96-1.26, P = 0.1725) and 0.84 (95% CI 0.69-1.02, P = 0.0741) for one SD increase of log-transformed smoking per day and drinks per week, and 1.31 (95% CI 1.08-1.58, P = 0.0051) for one SD increase in sedentary behavior. Genetically predicted waist circumference (OR = 1.26, 95% CI 1.11-1.43, P = 0.0004) and sedentary behavior (OR = 1.14, 95% CI 1.05-1.23, P = 0.0021) were associated with BPH after the adjustment of BMI.
This study supports independent causal roles of high waist circumference, BMI and sedentary behavior in BPH.

UNASSIGNED: Benign prostatic hyperplasia (BPH) is an age-related condition and its prevalence has increased as China\'s population ages. Transurethral resection of the prostate (TURP) remains the gold standard for treating moderate to severe BPH. Routine placement of a urinary catheter after TURP is often associated with catheter-related bladder discomfort (CRBD). The development of CRBD is related to an increased synthesis of prostaglandin (PG), and wrist-ankle acupuncture (WAA) can inhibit the expression of PG at the site of inflammation, thus alleviating CRBD symptoms. Here we evaluated the efficacy of WAA in alleviating CRBD in patients undergoing TURP.
UNASSIGNED: A total of 46 patients who underwent elective TURP in Hebei Provincial Hospital of Traditional Chinese Medicine from June 2022 to July 2022 were randomly divided into two groups according to the complete randomization method. The WAA group (n=23) and the control group (n=23). The WAA group received WAA, and the needles were retained for 24 h. The control group was treated with sham needles that did not penetrate the skin, and the needles were also retained for 24 h. At T1 (0 h after entering the ward), T2 (0.5 h after entering the ward), T3 (6 h after entering the ward), and T4 (24 h after entering the ward), CRBD severity score, visual analogue scale (VAS) and vital signs monitor were used for assessment. Accidents were recorded in the case report form. Graded data using Wlicoxon signed rank sum test, repeated measures using repeated measures analysis of variance.
UNASSIGNED: A total of 46 patients participated in this study, and 44 patients completed the experiment. At T2, T3, and T4, the severity of CRBD in the WAA group was significantly lower than that in the control group (all P<0.05), and the VAS pain score was significantly lower in the WAA group than in the control group (all P<0.05). In contrast, the vital signs, including mean arterial pressure (MAP), heart rate (HR), and blood oxygen saturation, showed no statistical significance (all P>0.05). No accident occurred in both groups.
UNASSIGNED: WAA can effectively relieve CRBD symptoms after TURP. WAA deserves further research and assessment for clinical practice.

OBJECTIVE: The objective of this sub-analysis of the PERSAT study was to evaluate the efficacy of hexanic extract of S. Repens (HESr) and alpha-blockers (AB), at 6 months in patients with moderate to severe LUTS/BPH.
METHODS: The PERSAT observational study was conducted in France by general practitioners on patients with BPH with an IPSS≥12 score. The primary endpoint was the percentage of responders (decrease in total IPSS score ≥ 3) at 6 months. Improvement in quality of life (IPSS-QoL) as well as patient satisfaction were also measured.
RESULTS: Of the 759 patients in the study, 324 treated with HESr and 309 with AB were reviewed at 6 months, with no change in treatment during follow-up. Characteristics at inclusion were globally similar with a mean IPSS of 18.2±4.9. The response rates at 6 months (IPSS-total decrease ≥ 3) were 93.7% and 94.8% for patients treated with HESr and AB, with a mean decrease in IPSS score of 10.1±5.6 points, which reached 13.6 and 14.8 points respectively, in severe patients (IPSS>19), without major difference between groups. More than 95% of HESr or AB patients reported a significant overall improvement in their LUTS/BPH. The most frequently reported adverse events with AB were ejaculation disorders (4.9%) and hypotension (4.2%) and with HESr digestive disorders (1.5%).
CONCLUSIONS: This sub-analysis of the PERSAT cohort reported the clinical efficacy of HESr and AB as a first-line treatment in the management of moderate or severe LUTS/BPH patients.

BACKGROUND: Prostate cancer (PCa) and benign prostatic hyperplasia (BPH) are the most common prostate disorders in the UK, which cause considerable ill health in older men. Transperineal template prostate biopsy (TTPB) has emerged as a reliable procedure for the histopathological diagnosis of PCa and BPH due to its higher cancer detection rates. Although antiseptic preparation and antibiotic prophylaxis are used to ensure safety in patients undergoing surgical intervention, post-operative complications, such as infection and bleeding are still unavoidable, resulting in re-admissions, with resource implications. Currently, there is no biomarker profile to predict outcomes or monitor patients during the post-operative course. The main aim of this single-centre observational clinical pilot-study was to investigate the role of inflammatory and infection biomarkers following TTPB and their association with post-operative complications.
METHODS: Forty-five patients scheduled for elective TTPB were recruited after informed consent at the Wrexham Maelor and Glan Clwyd Hospitals, North Wales, UK (n = 45). Prior to surgery, venous blood samples were collected at baseline and subsequently at 30, 120, and 240 min post-operatively. Urine samples were collected before and 120 min after the procedure. Serum procalcitonin (PCT), serum ferritin, and urine B2MG analysis were done using enzyme-linked fluorescent assay (ELFA) and the magnetic Luminex® multiplex performance assay was used to analyse IL-6, IL-8, IL-10 and TNF-α plasma concentrations. Data on clinical outcomes were collected from patients\' medical records.
RESULTS: Following TTPB, significant (p ≤ 0.05) increases were observed in uB2MG, IL-6, IL-8, IL-10 and TNF-α. Significant decreases were observed in ferritin (p ≤ 0.05). No significant change was observed in PCT concentration (p ≥ 0.05). One patient developed an infection and severe haematuria post-operatively following TTPB.
CONCLUSIONS: Although not confirmative, changes seen in biomarkers such as uB2MG, IL-10 and TNF-α in our observational clinical pilot-study may warrant further investigation, involving larger cohorts, to fully understand the role of these biomarkers and their potential association with post-operative complications such as infection and bleeding which can develop following TTPB for the diagnosis of PCa and BPH.

OBJECTIVE: Assess long-term outcomes of prostatic artery embolization (PAE) for patients with benign prostatic hyperplasia (BPH).
METHODS: Single centre retrospective study from 2009-2019 including 1072 patients who received PAE and had available follow-up. Patients were evaluated yearly at 1-10 years post PAE using the International Prostate Symptom Score (IPSS) and quality of life (QoL), prostate volume (PV), prostate-specific antigen (PSA), peak urinary flow rate (Qmax) and postvoid residual (PVR) volume. The need for prostatic medication, re-intervention rates, repeat PAE and prostatectomy rates were assessed with Kaplan-Meier survival analysis and compared between different embolic agents using Cox regression analysis.
RESULTS: Mean follow-up time was 4.39 ± 2.37 years. At last follow-up visit, mean IPSS and QoL improvements were - 10.14 ± 8.34 (p < .0001) and - 1.87 ± 1.48 (p < .0001) points, mean PV reduction was - 6.82 ± 41.11 cm3 (p = 0.7779), mean PSA reduction was - 1.12 ± 4.60 ng/mL (p = 0.9713), mean Qmax increase was 2.72 ± 6.38 mL/s (p = 0.0005), mean PVR reduction was - 8.35 ± 135.75 mL (p = 0.6786). There were 335 patients (31.3%) needing prostatic medication after PAE. Re-intervention rates were 3.4% at 1 year, 21.1% at 5 years and 58.1% at 10 years. Repeat-PAE rates were 2.3% at 1 year, 9.5% at 5 years and 23.1% at 10 years. Prostatectomy rates were 1.1% at 1 year, 11.6% at 5 years and 35.0% at 10 years. No significant differences were found between polyvinyl alcohol particles, Bead Block, Embospheres and Embozenes.
CONCLUSIONS: PAE induces durable long-term LUTS relief, with re-intervention rates of 20% in the first 5 years and 30%-60% > 5 years post-PAE.
