RESUMO
BACKGROUND: The use of dating applications for matchmaking and sexual exploits ("hookups") has increased, and this modern phenomenon has supplanted traditional socialization and relationship formation. To date, sociodemographic data on the use of dating apps has been limited. AIM: In this study, we sought to identify predictors associated with the use of dating apps in the United States. METHODS: Using cross-sectional data from the 2017-2019 National Survey of Family Growth, we examined sociodemographic determinants influencing the use of dating apps to find partners for sexual intercourse. We constructed survey-weighted regression models to study these associations, with additional sensitivity analyses performed within specific subgroups. Furthermore, this study investigated the correlation of app use with sexual frequency. OUTCOME: Study outcomes were participant data regarding reported use of dating apps for sexual intercourse in the 2017-2019 National Survey of Family Growth. RESULTS: A total of 11,225 respondents were examined, representing a survey-weighted total of approximately 143,201, 286 Americans. Among them, 757 respondents (6.7%), equating to approximately 8, 818, 743 individuals, reported dating app use for sexual hookups. Regression analysis revealed that factors such as male sex, White race, previous sexual experience, substance/alcohol use, history of sexually transmitted infections, same-sex attraction, and bisexuality increased the likelihood of dating app usage. Conversely, reduced odds of dating app use were observed among Catholics, Protestants, married/widowed individuals, and older respondents. Stratified analyses across various demographics, including male and female individuals aged 20 to 40 years, heterosexual, and lesbian, gay, and bisexual respondents, generally supported these trends. Notably, dating app use did not correlate with increased sexual frequency (adjusted incidence rate ratio: 1.10; 95% CI: 0.96-1.26; P = .16). CLINICAL IMPLICATIONS: Dating app use is prevalent among male patients and White individuals and correlates with increased sexually transmitted infection risk, alcohol/illicit substance use, past sexual experience, and popularity within the lesbian, gay, and bisexual community, all important considerations for public health interventions. Dating app use, however, was not associated with increased sexual encounters. STRENGTHS AND LIMITATIONS: Strengths of our study were the utilization of a national survey of individuals of reproductive age in the United States and focus on a clearly defined outcome of dating app utilization for the purposes of sexual intercourse. Limitations include self-reported survey responses and insufficient detail on the types and duration of dating app platforms and their use. CONCLUSIONS: Many sociodemographic factors, including male sex, White race, history of STIs, substance and alcohol use, and same-sex and bisexual attraction, were linked with dating app use. However, there was no increase in sexual frequency associated with dating app utilization. Further research is essential for integrating these technologies into the relational and sexual dynamics of individuals.
RESUMO
OBJECTIVES: Obstructing ureteral stones complicated by urinary tract infection are urologic emergencies that require prompt decompression. We explore the association of pregnancy with rates of and delays in decompression in a cohort of women of reproductive age. METHODS: Using the National Inpatient Sample from 2010 to 2015, a cross-sectional, descriptive analysis of women of reproductive age (15 to 44 years old) diagnosed with obstructing ureteral stones and urinary tract infection was performed and stratified by pregnancy status. Survey-weighted regression models were used to assess the association of pregnancy on decompression, delays in decompression, and hospital length of stay. Additional exploratory analyses on the association of timing and type of decompression with maternal-fetal outcomes were performed. RESULTS: A weighted total of 38 783 hospitalizations were identified, with 6.1% of admissions occurring in pregnant women. On multivariable regression, pregnant women with obstructing ureteral stones and urinary tract infection were 38% less likely of undergoing decompression (adjusted OR: 0.62; p < 0.001) compared with nonpregnant women. Among those decompressed, pregnant women had greater odds of delayed decompression (adjusted OR: 2.28; p < 0.001) and longer length of stay (adjusted IRR: 1.11; p = 0.007). Delayed decompression among pregnant women was associated with increased rates of C-section, early or threatened labor, fetal distress, and umbilical cord complications. CONCLUSIONS: Overall, pregnant women had reduced odds of decompression, as well as increased odds of delayed decompression, when compared with nonpregnant women of reproductive age. Delays in decompression among pregnant women were also associated with increased maternal and fetal complications.

OBJECTIVE: Cerebral hyperperfusion syndrome (CHS) is a rare but potentially devastating complication after carotid endarterectomies (CEA). Its symptoms range from new-onset unilateral headache (HA) to intracranial hemorrhage (ICH). Risk factors for CHS in the literature to date have not yet yielded a consensus. This study examines intraoperative and postoperative blood pressure variations as potential risk factors for HA. METHODS: A single-center retrospective review at a tertiary care center from January 2010 to November 2019 was performed. Inclusion criteria were all patients undergoing CEA for symptomatic or asymptomatic carotid disease. Patients with incomplete charts were excluded. Primary endpoints were new-onset unilateral HA or postoperative ICH. Data on intraoperative and postoperative mean arterial pressure (MAP), systolic blood pressure (SBP), the mode of endarterectomy, shunt placement, and contralateral carotid status were collected. RESULTS: There were 735 patients who met the inclusion criteria: 430 patients underwent modified eversion CEA (59%) and 305 patients for patch angioplasty (42%). The incidence of HA was 19% (n = 142) in our total cohort. Of the 19% with HA, 1.5% (n = 11) demonstrated no relief with analgesics and strict blood pressure control; noncontrast head computed tomography scans were performed subsequently. One patient (0.1%) had an ipsilateral ICH. Univariate analysis demonstrated that greater intraoperative MAP peak had the highest risk for HA (odds ratio [OR], 1.014; 95% confidence interval [CI], 1.007-1.022; P = .0002), followed by intraoperative MAP variability (OR, 1.011; 95% CI,1.005-1.018; P ≤ .0008), and peak intraoperative SBP (OR, 1.01; 95% CI, 1.004-1.015; P = .0011). An unpaired Student t test identified change in intraoperative MAP (P < .005), change in the SBP (P < .005), and peak SBP (P < .001) were significantly associated with HA. Interestingly, there was no significant difference between postoperative MAP variability and HA (P = .1). The mode of endarterectomy showed no statistically significant difference in risk for developing HA (OR, 1.165; 95%; 95% CI, 0.801-1.694; P = .42). CONCLUSIONS: Greater intraoperative variability in blood pressures are significantly associated with a higher risk of HA. Adhering to stricter intraoperative blood pressure parameters and limiting blood pressure variability may be beneficial at decreasing the incidence of CHS and its complications.

INTRODUCTION: Priapism is a urologic emergency that may require surgical intervention in cases refractory to supportive care. Exchange transfusion (ET) has been previously used to manage sickle cell disease (SCD), including in priapism; however, its utilization in the context of surgical intervention has not been well-established. AIM: To explore the utilization of ET, as well as other patient and hospital-level factors, associated with surgical intervention for SCD-induced priapism METHODS: Using the National Inpatient Sample (2010-2015), males diagnosed with SCD and priapism were stratified by need for surgical intervention. Survey-weighted regression models were used to analyze the association of ET to surgical intervention. Furthermore, negative binomial regression and generalized linear models with logarithmic transformation were used to compare ET vs surgery to length of hospital stay (LOS) and total hospital charges, respectively. MAIN OUTCOME MEASURES: Predictors of surgical intervention among patients with SCD-related priapism RESULTS: A weighted total of 8,087 hospitalizations were identified, with 1,782 (22%) receiving surgical intervention for priapism, 484 undergoing ET (6.0%), and 149 (1.8%) receiving combined therapy of both ET and surgery. On multivariable regression, pre-existing Elixhauser comorbidities (e.g. ≥2 Elixhauser: OR: 2.20; P < 0.001), other forms of insurance (OR: 2.12; P < 0.001), and ET (OR: 1.99; Pâ¯=â¯0.009) had increased odds of undergoing surgical intervention. In contrast, Black race (OR: 0.45; P < 0.001) and other co-existing SCD complications (e.g. infectious complications OR: 0.52; P < 0.001) reduced such odds. Compared to supportive care alone, patients undergoing ET (adjusted IRR: 1.42; 95% CI: 1.10-1.83; Pâ¯=â¯0.007) or combined therapy (adjusted IRR: 1.42; 95% CI: 111-1.82; P < 0.001) had a longer LOS vs. surgery alone (adjusted IRR: 0.85; 95% CI: 0.74-0.97; Pâ¯=â¯0.017). Patients receiving ET (adjusted Ratio: 2.39; 95% CI: 1.52-3.76; P < 0.001) or combined therapy (adjusted Ratio: 4.42; 95% CI: 1.67-11.71; Pâ¯=â¯0.003) had higher ratio of mean hospital charges compared with surgery alone (adjusted Ratio: 1.09; 95% CI: 0.69-1.72; Pâ¯=â¯0.710). CONCLUSIONS: Numerous factors were associated with the need for surgical intervention, including the use of ET. Those receiving ET, as well as those with combined therapy, had a longer LOS and increased total hospital charges. Ha AS, Wallace BK, Miles C, et al.

BACKGROUND: Growing evidence suggests a possible sex disparity in COVID-19 disease related outcomes. OBJECTIVE: To explore the sex disparity in COVID-19 cases and outcomes using New York City (NYC) population level data. SETTING: NYC surveillance data from February 29 to June 12, 2020. PARTICIPANTS: Individuals tested for COVID-19 in metropolitan NYC.Outcome Measurements and Statistical Analysis: Outcomes of interest included rates of COVID-19 case positivity, hospitalization and death. Relative risks and case fatality rates were computed for all outcomes based on sex and were stratified by age groups. RESULTS AND LIMITATIONS: 911,310 individuals were included, of whom 434,273 (47.65%) were male and 477,037 (52.35%) were female. Men represented the majority of positive cases (n=106,275, 51.36%), a majority of hospitalizations (n=29,847, 56.44%), and a majority of deaths (n=13,054, 59.23%). Following population level adjustments for age and sex, testing rates of men and women were equivalent. The majority of positive cases and hospitalizations occurred in men for all age groups except age >75 years, and death was more likely in men of all age groups. Men were at a statistically significant greater relative risk of case positivity, hospitalization, and death across all age groups except those <18 years of age. The most significant difference for case positivity was observed in the 65–74 age group (RR 1.22, 95%CI 1.19–1.24), for hospitalization in the 45–65 age group (RR 1.85, 95% 1.80–1.90), and for death in the 18–44 age group (RR 3.30, 95% CI 2.82–3.87). Case fatality rates were greater for men in all age-matched comparisons to women. Limitations include the use of an evolving surveillance data set and absence of further demographic characteristics such as ethnographic data. CONCLUSION: Men have higher rates of COVID-19 positivity, hospitalization, and death despite greater testing of women; this trend remains after stratification by age.

OBJECTIVE: To quantify the financial impact of complications after radical cystectomy (RC) and their associations with respective 90-day costs, as RC is a morbid surgery plagued by complications and the expenditure attributed to specific complications after RC is not well characterised. PATIENTS AND METHODS: We used the Premier Hospital Database (Premier Inc., Charlotte, NC, USA) to identify 9 137 RC patients (weighted population of 57 553) from 360 hospitals between 2003 and 2013. Complications were categorised according to Agency for Healthcare Research and Quality Clinical Classifications. Patients with and without complications were compared, and multivariable analysis was performed. RESULTS: An index complication increased costs by $9 262 (95% confidence interval [CI] 8 300-10 223) and a readmission complication increased costs by $20 697 (95% CI 18 735-22 660). The four most costly index complications (descending order) were venous thromboembolism (VTE), infection, wound and soft tissue complications, and pulmonary complications (P < 0.001, vs no complication). A complication increased length of stay by 4 days (95% CI 3.6-4.3). One in five patients were readmitted in 90 days and the four costliest readmission complications (descending order) were pulmonary, bleeding, VTE, and gastrointestinal complications (P < 0.001, vs no complication). Readmitted patients had multiple complications upon readmission (median of 3, interquartile range 2-4). On multivariable analysis, more comorbidities, longer surgery (>6 h), transfusions of >3 units, and teaching hospitals were associated with higher costs (P < 0.05), whilst high-volume surgeons and shorter surgeries (<4 h) were associated with lower costs (P < 0.05). CONCLUSIONS: Complications after RC increase index and readmission costs for hospitals, and can be categorised based on magnitude. Future initiatives in RC may also consider costs of complications when establishing quality improvement priorities for patients, providers, or policymakers.

Bone morphogenetic protein-2 (BMP-2), a member of the transforming growth factor-ß family, plays critical roles in cell differentiation, modeling and regeneration processes in several tissues. BMP-2 is also closely associated with various malignant tumors. microRNAs negatively and posttranscriptionally regulate gene expression and function as oncogenes or tumor suppressors. Herein, we report that miR-656 expression was significantly downregulated in glioma cell lines and tissues. We identified and confirmed that BMP receptor, type 1A (BMPR1A) is a direct target of miR-656. The expression of BMPR1A was negatively correlated with that of miR-656 in human glioma tissues. We further demonstrated that miR-656 suppressed glioma cell proliferation, neurosphere formation, migration and invasion with or without exogenous BMP-2. Engineered knockdown of BMPR1A diminished the antiproliferation effect of miR-656 in vitro. Moreover, the canonical BMP/Smad and non-canonical BMP/mitogen-activated protein kinase (MAPK) pathways were inhibited by miR-656 overexpression. Several cancer-related signaling molecules, including cyclin B, cyclin D1, matrix metalloproteinase-9, p21 and p27, were also involved in miR-656 function in glioma cells. The tumor-suppressing function of miR-656 was validated using an in vivo intracranial xenograft mouse model. Notably, ectopic expression of miR-656 markedly reduced tumor size and prolonged the survival of mice treated with or without BMP-2. These results elucidate the function of miR-656 in glioma progression and suggest a promising application for glioma treatment.

We present a case of reverse McConnell's sign, a rare echocardiographic finding of right ventricular apical hypokinesis and basal hyperkinesis, in a patient with acute respiratory distress syndrome and septic shock. Although multiple etiologies were hypothesized, providers attributed this cardiomyopathy to increased right heart afterload from hypoxic pulmonary vasoconstriction. Cardiac function normalized as the patient's respiratory failure and sepsis resolved. This study highlights the value of early echocardiography to help guide management in critical illness. In our case, this finding helped initiate diuresis and establish a baseline for monitoring cardiac function as this patient's critical illness resolved. Literature has most commonly associated reverse McConnell's sign with massive pulmonary embolism and, more rarely, takotsubo cardiomyopathy. Given the absence of PE, takotsubo, or other identifiable cause, this case suggests that reverse McConnell's sign may more generally indicate acutely increased right ventricular afterload rather than a specific diagnosis. When reverse McConnell's sign is detected, treatment should focus on reversible causes of elevated right heart pressure (e.g., volume overload, PE) and increased pulmonary resistance.
RESUMO
INTRODUCTION: Electronic patient messaging utilization has increased in recent years and has been associated with physician burnout. ChatGPT is a language model that has shown the ability to generate near-human level text responses. This study evaluated the quality of ChatGPT responses to real-world urology patient messages. METHODS: One hundred electronic patient messages were collected from a practicing urologist's inbox and categorized based on the question content. Individual responses were generated by entering each message into ChatGPT. The questions and responses were independently evaluated by 5 urologists and graded on a 5-point Likert scale. Questions were graded based on difficulty, and responses were graded based on accuracy, completeness, harmfulness, helpfulness, and intelligibleness. Whether or not the response could be sent to a patient was also assessed. RESULTS: Overall, 47% of responses were deemed acceptable to send to patients. ChatGPT performed better on easy questions with 56% of responses to easy questions being acceptable to send as compared to 34% of difficult questions (P = .03). Responses to easy questions were more accurate, complete, helpful, and intelligible than responses to difficult questions. There was no difference in response quality based on question content. CONCLUSIONS: ChatGPT generated acceptable responses to nearly 50% of patient messages with better performance for easy questions compared to difficult questions. Use of ChatGPT to help respond to patient messages can help to decrease the time burden for the care team and improve wellness. Artificial intelligence performance will likely continue to improve with advances in generative artificial intelligence technology.

Importance: The age of fathers at childbirth is rising, with an increasing number of births attributed to older fathers. While the impact of advanced paternal age has been documented, sociodemographic data about fathers aged 50 years and older remain scarce. Objectives: To explore sociodemographic and temporal trends among the oldest US fathers (age ≥50 years) and their associations with perinatal outcomes. Design, Setting, and Participants: This retrospective cross-sectional study included data from all US births from 2011 to 2022 using the National Vital Statistics System. Data were analyzed from August 2023 and May 2024. Exposures: Reported paternal age at childbirth. Main Outcomes and Measures: Outcomes of interest were sociodemographic factors, temporal trends in older fatherhood, and perinatal outcomes, including preterm birth, low birth weight, gestational diabetes, gestational hypertension, assisted reproductive technology (ART), rates of maternal primiparity, and the infant sex ratio. Results: From 2011 to 2022, the US recorded 46â¯195â¯453 births, with an overall mean (SD) paternal age of 31.5 (6.8) years and 484â¯507 (1.1%) involving fathers aged 50 years or older, 47â¯785 (0.1%) aged 60 years or older, and 3777 (0.008%) aged 70 years or older. Births to fathers aged 50 years or older increased from 1.1% in 2011 to 1.3% in 2022 (P for trend < .001). Fathers aged 50 years or older were more diverse, with variations in educational achievement and race and ethnicity. Marital status and maternal racial and ethnic and educational backgrounds also varied by paternal age and race. Despite controlling for maternal age and other sociodemographic and perinatal factors, every 10-year increase in paternal age was consistently associated with greater use of ART (eg, age 50-59 years: adjusted odds ratio [aOR], 2.23; 95% CI, 2.19-2.27), higher likelihood of first maternal birth (eg, age 50-59 years: aOR, 1.16; 95% CI, 1.15-1.17), and increased risks of preterm birth (eg, age 50-59 years: aOR, 1.16; 95% CI, 1.15-1.18) and low birth weight (eg, age 50-59 years: aOR, 1.14; 95% CI, 1.13-1.15) compared with fathers aged 30 to 39 years. No significant changes in the infant sex ratio were observed, except among fathers aged 70 years or older (aOR, 0.92; 95% CI, 0.86-0.99) and 75 years or older (aOR, 0.84; 95% CI, 0.73-0.97), who showed a decreased likelihood of having male offspring. Conclusions and Relevance: In this cross-sectional study of all US births from 2011 to 2022, the percentage attributed to older fathers, while small, increased. Notable variations in paternal and maternal race and education were identified. Older fatherhood was associated with increased ART use, first-time maternal births, adverse perinatal outcomes, and altered sex ratio. Further research of this population is crucial for improving patient counseling and family planning.

While consensus exists regarding risk factors for priapism, predictors of operative intervention are less well established. We assessed patient and hospital-level predictors associated with penile surgical intervention (PSI) for patients admitted with acute priapism, as well as length of stay (LOS) and total hospital charges using the National Inpatient Sample (2010-2015). Inpatients with acute priapism were stratified by PSI, defined as penile shunts, incisions, and placement of penile prostheses, exclusive of irrigation procedures. Survey-weighted logistic regression models were utilized to assess predictors of PSI. Negative binomial regression and generalized linear models with logarithmic transformation were used to compare PSI to LOS and total hospital charges, respectively. Among 14,529 weighted hospitalizations, 4,953 underwent PSI. Non-Medicare insurances, substance abuse, and ≥3 Elixhauser comorbidities had increased odds of PSI. Conversely, Black patients, sickle cell disease, alcohol abuse, neurologic diseases, malignancies, and teaching hospitals had lower odds. PSI coincided with shorter median LOS (adjusted IRR: 0.62; p < 0.001) and lower ratio of the mean hospital charges (adjusted Ratio: 0.49; p < 0.001). Additional subgroup analysis revealed penile incisions and shunts primarily associated with reduced LOS (adjusted IRR: 0.66; p < 0.001) and total hospital charges (adjusted Ratio: 0.49; p < 0.001). Further work is required to understand predictors of poor outcomes in these populations.

RESUMO
Background: Robot-assisted ureteral reimplantation (RAUR) is a relatively new minimally invasive procedure. As such, research is lacking, and the largest adult cohort studies include fewer than 30 patients. Our aim was to be the first population-based study to report on national utilization trends, factors associated with patient selection, inpatient outcomes, and the relative cost of RAUR for adults with benign ureteral disease (BUD). Materials and Methods: The National Inpatient Sample (2010-2015) was queried to identify all elective, nontransplant-related, open and robot-assisted reimplants for adult BUD. Survey-weighted logistic regression using Akaike Information Criterion identified patient-/hospital-level factors associated with robotic procedure. Survey-weighted regression models examined the association of robotic procedure with outcomes and charges. Results: A weighted total of 9088 cases were included: 1688 (18.6%) robot assisted and 7400 (81.4%) open. There were significantly increased odds of RAUR across consecutive years (odds ratio [OR] = 3.0, p < 0.001) and among patients operated on at private for-profit hospitals (OR: 2.1; p = 0.01), but significantly decreased odds among older patients (OR = 0.98, p < 0.001), those with Medicaid (OR = 0.5, p = 0.02), those with 2+ comorbidities (OR = 0.6, p = 0.009), and those operated on in western (OR = 0.5; p = 0.005) states. RAUR was significantly associated with a reduced length-of-stay (incidence rate ratio: 0.60; p < 0.001), decreased odds of blood transfusion (OR = 0.40; p < 0.001), and a lower mean ratio of total hospital charges (ratio: 0.71; p = 0.006). Conclusions: This is the first population-based study to report on the utilization and clinical benefits of RAUR for adult BUD. Open reimplantation remains the most common surgical technique utilized, despite the potential benefits of RAUR. Future research is needed to explore the mechanisms behind patient-/hospital-level factors and surgical selection. Work to investigate potential barriers in access to robotic procedure can help us provide equitable care across patient populations.

Background: The acute care surgery model has led to improved outcomes for emergent surgical conditions, but similar models of care have not been implemented in urology. Our department implemented an acute care urology (ACU) service in 2015, and the service evolved in 2018. We aimed to evaluate the impact of the ACU model on the management of nephrolithiasis. Materials and Methods: We conducted a retrospective review of all patients with urology consults in the emergency department for nephrolithiasis, who required surgical intervention from 2013 to 2019. Patients were divided into three cohorts based on date of consultation: Pre-ACU (2013-2014), Phase 1 (2015-2017), and Phase 2 (2018-2019). Results: We identified 733 patients with nephrolithiasis requiring intervention (162 pre-ACU, 334 Phase 1, and 237 Phase 2). Before ACU implementation, median time from consult to definitive intervention was 36 days. After ACU implementation, median time to intervention decreased to 22 days in Phase 1 (p < 0.001) and 15 days in Phase 2 (p < 0.001). On multivariable Cox regression, the hazard of definitive intervention improved in Phase 1 (hazard ratio [HR] 1.90, p < 0.001) and in Phase 2 (HR 1.80, p < 0.001). Rates of primary definitive intervention without initial decompression and loss to follow-up were also significantly improved, compared to the pre-ACU cohort. Conclusions: Implementation of a structured ACU service was associated with improved time to treatment for patients with acute nephrolithiasis, as well as increased primary definitive intervention and improved follow-up care.

BACKGROUND: Prostate abscess is a severe complication of acute bacterial prostatitis. To date, a population-based analysis of risk factors and outcomes of prostatic abscess has not been performed. METHODS: Using the National Inpatient Sample from 2010 to 2015, we identified rates of prostatic abscess among non-elective hospitalizations for acute prostatitis. Significant Elixhauser comorbidities and risk factors were analyzed using survey-weighted logistic regression. Additional survey-weighted regression models were constructed to analyze sepsis, in-hospital mortality, length of hospital stay (LOS), and total hospital charges. RESULTS: A weighted total of 126,103 hospitalizations for acute prostatitis was identified, with 6,775 (5.4%) hospitalizations with prostatic abscess. Numerous risk factors for prostatic abscess were identified, with a history of prostate biopsy (adjusted OR: 5.7; p < 0.001), complicated diabetes mellitus (adjusted OR: 3.23, p < 0.001), and urethral stricture (adjusted OR: 3.15; p < 0.001) having the greatest magnitude of developing abscess. Moreover, those diagnosed with prostatic abscess had increased odds of sepsis (adjusted OR: 1.71, p < 0.001), in-hospital mortality (adjusted OR: 2.73, p < 0.001), LOS (adjusted Incidence Rate Ratio: 1.86, p < 0.001), and total hospital charges (adjusted Ratio: 2.06, p < 0.001). CONCLUSIONS: Numerous risk factors were associated with the development of prostatic abscess, with those diagnosed experiencing greater odds of sepsis, in-hospital mortality, longer LOS, and greater hospital charges. Ultimately, better understanding of risk factors associated with this condition will enable clinicians to identify patients at high risk, thereby expediting and tailoring management.

Hypercalcemia and nephrolithiasis have been associated with various etiologies, including dysregulation of the parathyroid glands, malignancies, or sarcoidosis. Other causes of hypercalcemia, such as granulomatous disease resulting from silicone-based cosmetic injections, have been reported but without specific emphasis on nephrolithiasis. Herein, we report an unusual case of simultaneous bilateral obstructing ureteral calculi (SBUC) triggered by recalcitrant hypercalcemia and granulomatous disease due to silicone-based cosmetic injections. A careful surgical history, physical exam, and imaging identified the underlying etiology, which was confirmed by final histopathology. Using a multidisciplinary approach, the patient's condition was successfully managed with endoscopic procedures and concurrent corticosteroid therapy.
RESUMO
OBJECTIVE: To construct a risk prediction model to identify cases of difficult urethral catheterizations (DUC) in order to prevent complications from improper placement. MATERIALS AND METHODS: Using a single-institution database of urologic consults for Foley catheterizations from June 2016 to January 2020, a model to predict DUC in male patients was constructed. DUC was defined as requiring the use of a guidewire, cystoscopy, urethral dilation, and/or suprapubic tube (SPT) placement, while a simple Foley was defined as an uncomplicated placement of a regular or coudé catheter. A final model to predict DUC was constructed using multivariable logistic regression and internally validated using bootstrap statistics. RESULTS: A total of 841 consults were identified, with 181 (21.5%) classified as a DUC. On multivariable regression, patient-specific factors as overweight BMI (OR: 1.71; Pâ¯=â¯.014), urethral stricture disease (OR: 7.38; P < .001), BPH surgery (OR: 2.47; P < .001), radical prostatectomy (OR: 4.32; Pâ¯=â¯.001), and genitourinary (GU) prosthetic implants (OR: 3.44; Pâ¯=â¯.046) were associated with DUC. Situational factors such as blood at the meatus (OR: 2.40; P < .001), and consulting team (eg, surgery OR: 4.82; P < .001) were also significant. Bootstrap analysis of the final model demonstrated good overall accuracy (predictive accuracy: 75%). CONCLUSION: This model is a promising tool to help providers identify patients who likely require catheterization by a urologist and potentially reduce catheterization-related complications. The high rate of uncomplicated catheterizations also highlights the need for continuing education amongst healthcare professionals. External validation and application to the initial Foley encounter will shed light on its overall utility.

Group B Streptococcus (GBS) causes frequent urinary tract infection (UTI) in susceptible populations, including individuals with type 2 diabetes and pregnant women; however, specific host factors responsible for increased GBS susceptibility in these populations are not well characterized. Here, we investigate cathelicidin, a cationic antimicrobial peptide, known to be critical for defense during UTI with uropathogenic Escherichia coli (UPEC). We observed a loss of antimicrobial activity of human and mouse cathelicidins against GBS and UPEC in synthetic urine and no evidence for increased cathelicidin resistance in GBS urinary isolates. Furthermore, we found that GBS degrades cathelicidin in a protease-dependent manner. Surprisingly, in a UTI model, cathelicidin-deficient (Camp-/-) mice showed decreased GBS burdens and mast cell recruitment in the bladder compared to levels in wild-type (WT) mice. Pharmacologic inhibition of mast cells reduced GBS burdens and histamine release in WT but not Camp-/- mice. Streptozotocin-induced diabetic mice had increased bladder cathelicidin production and mast cell recruitment at 24 h postinfection with GBS compared to levels in nondiabetic controls. We propose that cathelicidin is an important immune regulator but ineffective antimicrobial peptide against GBS in urine. Combined, our findings may in part explain the increased frequency of GBS UTI in diabetic and pregnant individuals.IMPORTANCE Certain populations such as diabetic individuals are at increased risk for developing urinary tract infections (UTI), although the underlying reasons for this susceptibility are not fully known. Additionally, diabetics are more likely to become infected with certain types of bacteria, such as group B Streptococcus (GBS). In this study, we find that an antimicrobial peptide called cathelicidin, which is thought to protect the bladder from infection, is ineffective in controlling GBS and alters the type of immune cells that migrate to the bladder during infection. Using a mouse model of diabetes, we observe that diabetic mice are more susceptible to GBS infection even though they also have more infiltrating immune cells and increased production of cathelicidin. Taken together, our findings identify this antimicrobial peptide as a potential contributor to increased susceptibility of diabetic individuals to GBS UTI.

Urinary tract infection (UTI) is a prominent global health care burden. Although UTI is readily treated with antibiotics in healthy adults, complicated cases in immune-compromised individuals and the emerging antibiotic resistance of several uropathogens have accelerated the need for new treatment strategies. Here, we surveyed the composition of urinary exosomes in a mouse model of uropathgenic Escherichia coli (UPEC) UTI to identify specific urinary tract defense constituents for therapeutic development. We found an enrichment of the iron-binding glycoprotein lactoferrin in the urinary exosomes of infected mice. In subsequent in vitro studies, we identified human bladder epithelial cells as a source of lactoferrin during UPEC infection. We further established that exogenous treatment with human lactoferrin (hLf) reduces UPEC epithelial adherence and enhances neutrophil antimicrobial functions including bacterial killing and extracellular trap production. Notably, a single intravesicular dose of hLf drastically reduced bladder bacterial burden and neutrophil infiltration in our murine UTI model. We propose that lactoferrin is an important modulator of innate immune responses in the urinary tract and has potential application in novel therapeutic design for UTI.

PURPOSE: Postoperative delirium (PD) is associated with poor outcomes and increased health care costs. The incidence, outcomes, and cost of delirium for major urologic cancer surgeries have not been previously characterized in a population-based analysis. MATERIALS AND METHODS: We performed a population-based, retrospective cohort study of patients with PD at 490 US hospitals between 2003 and 2013 to evaluate the incidence, outcomes, and cost of delirium after radical prostatectomy, radical nephrectomy, partial nephrectomy, and radical cystectomy (RC). Delirium was defined using ICD-9 codes in combination with postoperative antipsychotics, sitters, and restraints. Regression models were constructed to assess mortality, discharge disposition, length of stay (LOS), and direct hospital admission costs. Survey-weighted adjustment for hospital clustering achieved estimates generalizable to the US population. RESULTS: We identified 165,387 patients representing a weighted total of 1,097,355 patients. The overall incidence of PD was 2.7%, with the greatest incidence occurring after RC, with 6,268 cases (11%). Delirious patients had greater adjusted odds of in-hospital mortality (odds ratio [OR] = 3.65, P<0.001), 90-day mortality (OR = 1.47, P = 0.013), discharge with home health services (OR = 2.25, P<0.001), discharge to skilled nursing facilities (OR = 4.64, P<0.001), and a 0.9-day increase in median LOS (P<0.001). Patients with delirium also experienced a $2,697 increase in direct admission costs (P<0.001), with the greatest costs incurred in RC patients ($30,859 vs. $26,607; P<0.001). CONCLUSIONS: Patients with PD after urologic cancer surgeries experienced worse outcomes, prolonged LOS, and increased admission costs. The greatest incidence and costs were seen after RC. Further research is warranted to identify high-risk patients and devise preventative strategies.
