Eosinophilic cystitis mimicking bladder tumor: A case report.

Eosinophilic cystitis (EC) is a rare inflammatory condition characterized by eosinophilic infiltration into the bladder wall. It often presents symptoms common to urological issues such as urinary tract infections, hematuria, bladder stones, or bladder neoplasms. Here, we describe a case of a 44-year-old male veteran with a history of multiple tuberculosis episodes who presented to the Emergency Department with dysuria, suprapubic pain, and gross hematuria. Initial imaging and cystoscopy concerned bladder neoplasia; however, subsequent pathological evaluation showed EC. This case underscores the importance of considering EC in the differential diagnosis of bladder tumors, especially when imaging describes bladder wall thickening in a patient without risk factors for bladder malignancy.

Risk Factors for Penile Fracture After Intralesional Collagenase Clostridium histolyticum in Peyronie's Disease.

OBJECTIVE: To evaluate risk factors leading to corporal rupture after Collagenase Clostridium histolyticum (CCh). Peyronie's disease (PD) is a fibrotic condition of the penis characterized by abnormal plaque formation. Intralesional CCh is the only FDA-approved medication for PD, however, it can lead to corporal rupture, a potential surgical emergency. METHODS: We retrospectively reviewed medical records from Veterans diagnosed with PD who were under treatment with CCh using the Veterans Administration Informatics and Computing Infrastructure (VINCI). Using International Classification of Diseases and Current Procedural Terminology codes, we identified men who suffered a corporal rupture after CCh. Individual charts were reviewed to determine potential risk factors and events leading to corporal rupture. RESULTS: We identified 17,647 veterans who were diagnosed with PD, of which 8.7% (1541) received at least one injection of CCh for PD. Of them, 0.7% (11/1541) veterans suffered corporal rupture. Within these 11 patients, the median number of CCH injections was 6 with a median initial curvature of 35°. Fracture occurred at a median of 8days after CCH injection. The majority of fractures were secondary to spontaneous erections or sexual intercourse. Finally, six patients had their fracture repaired surgically while the remaining were managed conservatively. CONCLUSION: Most fractures occurred within 2weeks of CCh injections and were associated with sexual intercourse and spontaneous morning erections.

Biopsychosocial approach to male chronic pelvic pain syndrome: recent treatments and trials.

INTRODUCTION: Chronic pelvic pain syndrome (CPPS) is a common urologic condition that can cause significant disability in affected individuals. Physiologic explanations of chronic pain are often incomplete; appropriate management of CPPS includes recognition of biological, psychological, and social elements, known as the biopsychosocial model. OBJECTIVE: The aim of this narrative review is to investigate treatments for men with CPPS, with a special focus on those utilizing the biopsychosocial model of care. METHODS: A comprehensive literature search was conducted on the electronic databases PubMed, Embase, and Cochrane Library, using relevant Medical Subject Heading terms and keywords related to CPPS treatments. The search was limited to studies published in English from inception to January 2023. Additionally, reference lists of selected studies were manually reviewed to find studies not identified by the initial search. Studies were included if they investigated pharmacologic or nonpharmacologic treatments for men with CPPS. RESULTS: A total of 30 studies met the inclusion criteria. Antibiotics, α-blockers, nonsteroidal anti-inflammatory drugs, gabapentinoids, antidepressants, and phosphodiesterase type 5 inhibitors were among the pharmacologic agents included in trials attempting to reduce symptoms of male CPPS. Studies that focused on treating CPPS without medication included interventions such as shockwave therapy, acupuncture, physical therapy, botulinum toxin, cryotherapy, electrotherapy, exercise, and cognitive behavioral therapy. CONCLUSION: α-Blockers and nonsteroidal anti-inflammatory drugs have shown promising results in treating CPPS in men, while the effectiveness of antibiotics remains controversial. Antidepressants and phosphodiesterase type 5 inhibitors may also be useful in decreasing symptoms in patients with CPPS. Treatments such as pelvic floor muscle therapy, acupuncture, shockwave therapy, and cognitive behavioral therapy must be considered effective complements to medical management in men with CPPS. While these interventions demonstrate benefits as monotherapies, the individualization and combination of treatment modalities are likely to result in reduced pain and improved quality of life.

Platelet-rich Plasma for the Treatment of Erectile Dysfunction: A Prospective, Randomized, Double-blind, Placebo-controlled Clinical Trial.

PURPOSE: We assessed the safety and efficacy of 2 injections of platelet-rich plasma for treating mild to moderate erectile dysfunction by conducting a prospective, randomized, double-blind, placebo-controlled clinical trial. MATERIALS AND METHODS: Men with mild to moderate erectile dysfunction (International Index of Erectile Function scores 11-25) were randomized to receive either 2 injections of platelet-rich plasma or placebo separated by 1 month. Primary outcome was percentage of men meeting minimum clinically important difference at 1 month after the second injection. Secondary outcomes were change in International Index of Erectile Function at 1, 3, and 6 months, and changes in penile vascular parameters and adverse events at 6 months. RESULTS: We randomized 61 men: 28 into platelet-rich plasma and 33 into placebo. There was no difference between groups in percentage of men meeting minimum clinically important difference at 1 month: 14 (58.3%) in platelet-rich plasma vs 15 (53.6%) in placebo (P = .730). Mean International Index of Erectile Function-Erectile Function domain changed from 17.4 (95% CI 15.8-19.0) to 21 (17.9-24.0) at 1 month in men receiving platelet-rich plasma, vs 18.6 (17.3-19.8) to 21.6 (19.1-24.1) in the placebo group; however, there was no significant difference between groups (P = .756). There were no major adverse events and only 1 minor adverse event in each group. There were no changes in penile Doppler parameters from baseline to 6 months. CONCLUSIONS: The results of our prospective, double-blind, randomized, placebo-controlled clinical trial suggest that 2 injections of intracavernosal platelet-rich plasma separated by 1 month in men with mild to moderate erectile dysfunction is safe, but we found no difference in efficacy between platelet-rich plasma and placebo.

A Phase 2 Randomized, Placebo-controlled Crossover Trial to Evaluate Safety and Efficacy of Platelet-rich Plasma Injections for Peyronie's Disease: Clinical Trial Update.

Intralesional injection of platelet-rich plasma for Peyronie's disease appears to be safe according to early observations from an ongoing clinical trial. Efficacy data remain elusive until completion of the trial.

Collagenase Clostridium histolyticum Treatment Improves Degree of Curvature in Peyronie's Disease with Calcified Plaques.

BACKGROUND: Peyronie's disease (PD) is a fibrotic condition of the penis characterized by abnormal plaque formation. Intralesional collagenase Clostridium histolyticum (CCh) is effective in noncalcified PD; however, its effectiveness in calcified PD is not well characterized. OBJECTIVE: To assess curvature improvement in calcified PD plaques treated with CCh. DESIGN, SETTING, AND PARTICIPANTS: We prospectively evaluated men with calcified PD electing CCh treatment at our institution from October 2018 to November 2020. We assessed curvature with artificial erection and goniometer before and at least 3 mo after treatment. We classified the type of plaque calcification based on ultrasound. INTERVENTION: Intralesional CCh. Each treatment cycle consisted of two CCh injections (0.58 mg) into the plaque at the point of maximal penile curvature. The second injection was performed 72 h to 1 wk later, after which participants began modeling. All men were intended to receive a total of eight injections in four cycles, each 6 wk apart. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Change in penile curvature after CCh was measured. We assessed for differences in outcomes based on the number of injections and type of calcification. Unless otherwise specified, data are presented as medians (interquartile range). RESULTS AND LIMITATIONS: Sixty men with calcified PD elected CCh; 47 had complete follow-up data. Thirty-nine men completed treatments with eight injections, while the remaining discontinued after a median of five (four to six) injections. There was no difference in response between type 2 and type 3 plaques. Curvature significantly improved by 17.5° (37.5-10.0°) in patients who completed treatment and by 15.0° (20.0-0.0°) in those who discontinued. Limitations include a small sample. CONCLUSIONS: Men with calcified PD plaques improve with CCh treatment and show similar improvements regardless of calcification type. PATIENT SUMMARY: In this study, we evaluated the efficacy of collagenase Clostridium histolyticum (CCh) treatment in calcified Peyronie's disease (PD) plaques. We found that treatment in calcified plaques demonstrated significant improvement in curvature and the grading of calcification did not impact the degree of curvature improvement. We conclude that participants with calcified PD plaques can benefit from nonsurgical CCh treatment.

Rationale and Design for the COCKTAIL Trial: A Single-center, Randomized, Double-blind, Sham-controlled Study Combining Shockwave Therapy and Platelet-rich Plasma for Erectile Dysfunction.

Restorative therapies are a promising option for the treatment of erectile dysfunction. Several studies have assessed platelet-rich plasma and shockwave therapy alone. However, COCKTAIL is the first study to evaluate the synergistic effects of these two therapies in combination.

Restorative therapy clinical trials for erectile dysfunction: a scoping review of endpoint measures.

Given the lack of regulatory approval for restorative therapies for the treatment of erectile dysfunction, we hypothesized that clinical trials would vary in methodology and endpoint measurements. Our objective was to analyze methodological approaches and outcome measures of clinical trials evaluating restorative therapies for erectile dysfunction. Data was extracted from clinicaltrials.gov on trials which contained the keywords "erectile dysfunction". We evaluated trials initiated between 2004 and 2021 which listed a restorative therapy intervention. We identified 95 trials investigating energy-based/shockwave therapies (60/95), stem cell therapies (25/95), platelet-based therapies (6/95), and others (4/95). Only 41.1% of the trials evaluated safety. The most common efficacy endpoint was International Index of Erectile Function and Sexual Health Inventory for Men, and only 29.5% utilized penile Doppler. Thirty (31.6%) trials had been completed yet only 3 (3.2%) have published results. We found substantial heterogeneity in methodological approach in the trials. Subjective measures of erectile function were commonly reported, but definitions of inclusion criteria and objective outcome measures were inconsistent. These results provide a basis for the design of future clinical trials to improve the quality of trial data and aid in the development of standardized criteria for erectile dysfunction clinical trials.

The incidence of surgical intervention in veterans treated with Collagenase clostridium histolyticum.

Peyronie's disease (PD) can be managed with surgery or intralesional injections of Collagenase clostridium histolyticum (CCH) however both are associated with side effects and variable results. It is unclear how many patients elect to undergo additional surgical correction after CCH. To answer this, we analyzed the Department of Veterans Affairs Informatics and Computing Infrastructure (VINCI) software. We performed a retrospective analysis over a 5-year period for patients with PD, at least one injection of CCH and surgical CPT codes. In total, 17,646 patients with PD were analyzed with 1541 treated with CCH. Only 51 (3.3%) were treated with secondary surgical intervention after CCH. Three main surgical procedures were performed: penile plication (51%), penile prosthesis (29%) and plaque excision and grafting (20%). Of the 51 men who underwent surgical corrections post CCH, the most common reason was lack of response/residual curvature (62.8%), followed by ED (29.4%). Previous literature shows that CCH was effective for only 60.8% of patients, potentially leaving the remaining in need of additional treatment. Despite this we found that only 3.3% received secondary therapy in the VA medical system, with residual curvature being the most common reason.

The Interest in Permanent Contraception Peaked Following the Leaked Supreme Court Majority Opinion of Roe vs. Wade: A Cross-Sectional Google Trends Analysis.

Introduction With the leaked Supreme Court draft regarding Roe vs. Wade, substantial public reactions followed as the horizon of abortion laws within the United States of America have been changing. We sought to compare internet searches for vasectomy and tubal ligation seven days following the leaked draft on May 2, 2022. Methods We used public data provided by Google Trends to investigate the interest and geographic distribution of searches for the two forms of permanent contraception: Vasectomy and tubal ligation. We calculated the mean Search Volume Index (SVI) of these terms. Data analysis was performed with Microsoft Excel Version 16.60 (Redmond, USA), and comparisons between groups were performed using paired t-tests. Results The term 'vasectomy' saw a 121% increase (p=0.0063), and 'tubal ligation' had a 70% (p=0.029) increase compared to the week prior. 49/50 states had increased search inquiries for each term. However, the North and Southwestern regions of the U.S. had increased relative surge for vasectomy and the Midwest region for tubal ligation procedures, respectively. South Dakota and Idaho, with trigger laws that banned abortion immediately following the overturn of Roe vs. Wade, had the greatest surge in SVI for tubal ligation and vasectomy, respectively. Conclusion Our study indicates that with the potential overturn of Roe vs. Wade, there was a significantly increased interest in these two forms of permanent contraception. Future studies should investigate specific concerns and questions patients may have when it comes to the different options of contraception.

An evaluation of race-based representation among men participating in clinical trials for prostate cancer and erectile dysfunction.

Background: Inclusion of ethnic/racial minorities in clinical trials is essential to fully assess therapeutic efficacy. It is well-known that populations respond dissimilarly to interventions. Our objective is to analyze the inclusion of minority men in clinical trials for erectile dysfunction (ED). Methods: We searched ClinicalTrials.gov for the disease keyword: "Erectile Dysfunction" and used "Prostate Cancer" for comparison. Completed trials which reported demographic data were included for analysis. Literature was reviewed to determine the prevalence of ED and prostate cancer (PC) among Hispanic, Black, White, and Asian men. The proportion of individuals of each group that participated in trials is divided by the proportion of each group in the disease population to calculate the "Participation to Prevalence Ratio" (PPR). PPRs between 0.8 and 1.2 indicates adequate representation, <0.8 is under-representation and >1.2 is over-representation. Results: A total of 312 trials were assessed: 289 for prostate cancer and 23 for ED. Hispanic men comprised 11.8% of ED trial participants and 4.6% of prostate cancer trial participants, yet represented 18% of ED patients and 7.3% of PC patients. Black/African-American (AA) men accounted for 10.2% of ED trial participants and 9.4% of PC trial participants, but comprise 16% of ED patients, and 16.3% of PC patients. Hispanic and AA men are under-represented in trials for ED and Prostate Cancer (Hispanic ED PPR = 0.66; Hispanic PC PPR = 0.63; AA ED PPR = 0.64; AA PC PPR = 0.58). Conclusion: Our analysis shows that both Hispanic and AA men are underrepresented in both ED and PC clinical trials.

Platelet Rich Plasma (PRP) Growth Factor Concentration Varies in Men With Erectile Dysfunction.

BACKGROUND: Platelet Rich Plasma (PRP) is a novel therapy rich in growth factors and cytokines used to target the underlying causes of erectile dysfunction (ED). It is not known, however, if the composition of growth factors in PRP varies between men. AIM: To evaluate PRP growth factor variability among men with ED. METHODS: Whole blood was collected from 8 participants with at least a 6-month history of ED. Seven men with Peyronie's disease and 1 healthy male (without sexual dysfunction) were used as the control group. PRP was extracted from whole blood using the Arthrex Angel system. A Human Growth Factor Antibody Array for 41 proteins was performed using 3 participants and the healthy control. Using all 16 samples, quantitative detection of factors from the array that were decreased by 1.5-fold were validated with western blot. OUTCOMES: From the growth factor array, 2 growth factors-granulocyte-macrophage colony stimulating factor and transforming growth factor-ß were identified as having a 1.5-fold decrease between the participants and the control. Vascular endothelial growth factor (VEGF) was selected because androgens can upregulate VEGF production. Other than a weak negative correlation between VEGF expression and age, we found no correlation between growth factor expression for granulocyte-macrophage colony stimulating factor or transforming growth factor-ß and age, body mass index, or comorbidities. CLINICAL TRANSLATION: PRP growth factor concentration appears to vary among men with ED. PRP treatment for ED may need to be personalized for patients, depending on individual growth factor concentration. STRENGTHS AND LIMITATIONS: This study demonstrates the variability in PRP growth factors among men with ED. This is an important finding in the investigation of PRP as a restorative treatment option for men with ED. Our study, however, was limited by a small sample size. CONCLUSION: PRP growth factors vary among men with ED. Khodamoradi K, Dullea A, Golan R, et al. Platelet Rich Plasma (PRP) Growth Factor Concentration Varies in Men With Erectile Dysfunction.

Efficacy and Safety of Human Chorionic Gonadotropin Monotherapy for Men With Hypogonadal Symptoms and Normal Testosterone.

Background Male hypogonadism has a prevalence of about 6% and is defined by two-morning testosterone levels below 300 ng/dl associated with symptoms. This definition presents a challenging problem for patients without other medical problems but with symptoms of low testosterone (T) who do not meet the biochemical criteria for therapy. Objectives Our objective was to evaluate changes in symptoms and side effects in men with T levels >300ng/dL using human chorionic gonadotropin (hCG) monotherapy for the treatment of hypogonadal symptoms. Methods After IRB approval, 31 male patients treated with hCG monotherapy for low T symptoms were retrospectively reviewed. We evaluated changes in hormones, hypogonadal symptoms, and the incidence of thromboembolic events before and after starting hCG. Results We found subjective improvement in erectile dysfunction, 86% (19/22), and libido, 80% (20/25), with no patient experiencing a thromboembolic event. In addition, no change was observed in the follicle-stimulating hormone, luteinizing hormone, estradiol, hematocrit, hemoglobin A1c, and prostate-specific antigen. Conclusion Weekly treatment with hCG appears safe and can improve hypogonadal symptoms in patients with T >300 ng/dl without changes to hematocrit, prostate-specific antigen, and hemoglobin A1c.

The Safety of Human Chorionic Gonadotropin Monotherapy Among Men With Previous Exogenous Testosterone Use.

Background and objective Human chorionic gonadotropin (hCG) is homologous to luteinizing hormone (LH) and stimulates endogenous testosterone (T) production. Current American Urological Association (AUA) guidelines recommend hCG for T-deficient men who wish to preserve their fertility. However, there is no data available regarding the long-term efficacy and safety of hCG monotherapy in men with a history of exogenous T use. We hypothesized that transitioning to hCG would be a safe and effective option in this population. Methodology We performed a retrospective analysis involving 28 men with previous exogenous T use who were switched to hCG monotherapy and underwent follow-up lab work at least one month later. We evaluated changes in hormones [T, LH, follicle-stimulating hormone (FSH), and estradiol], hematocrit (HCT), glycated hemoglobin (HbA1c), and prostate-specific antigen (PSA). Results Among the entire cohort, we found no significant change in mean hormone levels (including T), HbA1c, or PSA. There was a significant (p<0.05) decrease in HCT (45.27 ±4.06 to 44.16 ±3.48%, n=15). No thromboembolic events were reported. Additionally, among men who had their baseline labs completed outside their previous T therapy therapeutic time window prior to starting hCG monotherapy, there was a statistically significant increase in mean T levels (307.36 ±148.74 to 422.11 ±268.15 ng/dL, n=30 and 31, pre- and post-hCG, respectively) and a statistically significant decrease in mean PSA levels (0.91 ±0.35 to 0.69 ±0.23 ng/mL, n=5). Conclusions These results suggest that hCG is a safe and effective alternative to traditional T therapy for men with a history of exogenous T use and may lead to an advantageous decrease in HCT. hCG may serve as an alternative form of T therapy with a lower risk for secondary erythrocytosis, and further research is warranted to gain deeper insights into the topic.

Is tadalafil associated with decreased risk of major adverse cardiac events or venous thromboembolism in men with lower urinary tract symptoms?

PURPOSE: To evaluate the association of tadalafil, a phosphodiesterase-5 inhibitor (PDE5I), with major adverse cardiac events (MACE) or venous thromboembolism (VTE) in men with lower urinary tract symptoms (LUTS). METHODS: Data was obtained from the TriNetX Research Network, ICD-10 codes were used to identify men with LUTS, MACE, and VTE. In addition, demographic characteristics and use of tadalafil or alpha-blocker was evaluated. Then, unbalanced and balanced association analyses was performed to assess the relation between tadalafil and/or alpha-blocker use with MACE/VTE. RESULTS: After participant selection, analysis included 821,592 men that did not use an alpha blocker or tadalafil, 5,004 men that used tadalafil but no alpha blocker, 327,482 men that used an alpha blocker but no tadalafil, and 6,603 men that used both an alpha blocker and tadalafil. On balanced analysis, tadalafil was independently associated with a decreased risk of MACE/VTE within a 3-year time period (OR = 0.59, 95%CI 0.49-0.70, p < 0.0001). Among men with a history of alpha blocker use, tadalafil use was also independently associated with a decreased risk of MACE or VTE, both before and after controlling for potentially confounding variables (OR = 0.57, 95%CI: 0.50-0.66; p < 0.0001). CONCLUSIONS: In our study, tadalafil was associated with a decreased risk of MACE/VTE in men with LUTS with and without a history of alpha blocker use. It is time to perform further long-term prospective randomized studies to further analyze the cardiovascular effects of PDE5Is as combination treatment with alpha blockers in the management of LUTS.

COVID-19 Infection Is Associated With New Onset Erectile Dysfunction: Insights From a National Registry.

INTRODUCTION: The short- and long-term effects of coronavirus disease 2019 (COVID-19) on erectile function and penile vasculature remains poorly understood and is of particular importance as the virus has been found to be present within the penile tissue. AIM: We determined the association of COVID-19 infection and subsequent diagnoses of erectile dysfunction. METHODS: We assessed the risk of ED in men with COVID-19 in the United States (US) using the TriNetX Research Network, a federated electronic medical records network of over 42 healthcare organizations and 66 million patients from the US. We identified adult men (≥ 18 years) with a recorded COVID-19 infection (ICD-10-CM B34.2, U07.1, U07.2, J12.81, J12.82, B97.29) since January 1, 2020, and compared them to an equivalent number of adult men who did not have COVID-19 over the same timeframe. Men with prior history or diagnosis of ED before January 1, 2020 were excluded. We accounted for confounding variables through propensity score matching for age, race, body mass index (BMI), and history of the following comorbid medical conditions: diabetes mellitus (E11), hypertension (I10), ischemic heart disease (I20-25), or hyperlipidemia (E78). OUTCOMES: We assessed the association between COVID-19 and ED (N52) as a primary outcome through regression analysis with statistical significance assessed at P< .05. RESULTS: Prior to propensity score matching, men with COVID-19 were found to be older than men without COVID-19 (47.1 ± 21.4 vs 42.4 ± 24.3 years). Additionally, men with COVID-19 were noted to have increased prevalence of diabetes mellitus (DM) and hypertension (HTN) when compared to men without COVID-19 (13% DM and 27% HTN vs 7% DM and 22% HTN). After propensity score matching, we compared 230,517 men with COVID-19 to 232,645 men without COVID-19 and found that COVID-19 diagnosis was significantly associated with ED (odds ratio 1.20, 95% confidence interval 1.004-1.248, P= .04). CLINICAL IMPLICATIONS: Our findings indicate that clinicians should consider evaluating erectile dysfunction among men with recent COVID-19 diagnoses and counsel them regarding the risk of developing erectile dysfunction. STRENGTHS AND LIMITATIONS: Strengths include large sample size and adjustment for confounding variables. Limitations include reliance on a global federated dataset, retrospective study design, and lack of data regarding ED (mild vs moderate vs severe), COVID-19 infection severity, or history of prostate cancer and radiation. CONCLUSION: There is an increased chance of new onset erectile dysfunction post-COVID-19 infection.Chu KY, Nackeeran S, Horodyski L, et al.

The potential of platelet-rich plasma injections and stem cell therapy for penile rejuvenation.

Penile concerns include erectile dysfunction (ED) and Peyronie disease (PD). Restorative therapies including Stem Cell Therapy (SCT) and Platelet Rich Plasma (PRP) injections are proposed to treat these concerns. SCT encompasses the harvesting and injection of mesenchymal stem cells or stromal vascular fractions from various tissue sources. PRP is derived autologously from a patient's plasma and is then injected into the penile tissue. These therapies repair damaged penile tissue and promote both new cellular and vascular growth, as demonstrated in basic science studies. Human trials on SCT and PRP for both ED and PD and have yielded promising results with few side effects. While encouraging, small cohort size and lack of blinding or placebo control limit these studies' external validity. Recently, the first double-blinded randomized controlled trial on PRP for ED was published, providing significant evidence of efficacy. With the rapid commercial availability of SCT and PRP for ED and PD, it is imperative to perform more randomized and placebo-controlled trials with standardized procedures and preparations to evaluate efficacy and safety. This narrative review will summarize the available literature on these penile restorative therapies to date.

Comparison of American Urological Association and Endocrine Society guidelines on testosterone replacement.

Low testosterone affects an increasing number of patients each year resulting in a steady increase in prescriptions for testosterone replacement therapy (TRT). In 2018, the American Urological Association (AUA) and the Endocrine Society (ES) published their guidelines for treating patients with low testosterone. While the two guidelines are similar, significant differences exist. In this review, we compare and analyze the AUA and ES guidelines in terms of diagnosis and definition, workup, monitoring of side effects, treatment outcomes for TRT, and how these guidelines are applied in our practice.
