Pathologic and survival outcomes following radical cystectomy for "progressive" and "de novo" muscle-invasive bladder cancer: A meta-analysis stratified by neoadjuvant chemotherapy status.

OBJECTIVE: To compare survival and pathologic outcomes in patients with progressive muscle-invasive bladder cancer (pgMIBC) and de novo muscle-invasive bladder cancer (dnMIBC) after radical cystectomy (RC), with a focus on the role of neoadjuvant chemotherapy (NAC). METHODS: A comprehensive literature search was conducted on PubMed and EMBASE databases to identify studies comparing pgMIBC to dnMIBC. Survival outcomes, including cancer-specific survival (CSS), overall survival (OS), and recurrence-free survival (RFS), and pathologic outcomes (rates of ≤pT1, pT0, pT3/T4, and pN+ disease) were compared between pgMIBC and dnMIBC. RESULTS: The analysis included 19 cohorts from 16 studies, categorized into 3 groups based on NAC use: 1. patients who underwent RC and were all treated with NAC (RC + NAC only group); 2. patients who underwent RC, with or without NAC (RC +/- NAC group); 3. patients who only underwent RC without NAC (RC only group). Compared to dnMIBC, pgMIBC demonstrated worse outcomes for CSS, OS, and RFS. In the RC + NAC only group (3 cohorts), the hazard ratio (HR) for CSS was 1.52 (95% confidence interval [CI] = 1.05-2.2), while the HR for OS was 1.46 (95%CI = 1.05-2.02). Similarly, in the RC +/- NAC group (6 cohorts for CSS and 3 cohorts for OS), the HR for CSS was 1.27 (95%CI = 1.05-1.55), and the HR for OS was 1.27 (95%CI = 1.08-1.51). There were no significant differences observed in pathologic outcomes, including rates of ≤pT1, pT0, and pT3/T4 disease, across all subgroups. However, pgMIBC was associated with a higher risk of nodal metastatic (pN+) disease in the RC + NAC only group (4 cohorts, relative risk [RR] = 1.43, 95%CI = 1.12-1.84). CONCLUSIONS: The findings highlight the potentially worse prognosis in patients with pgMIBC compared to dnMIBC, even with the modern use of NAC. The study emphasizes the importance of careful patient counseling, further classification of patients for treatment selection, and the consideration of additional or innovative systemic therapies for pgMIBC.

Gain of Chromosome 5q Predicts a Favorable Prognosis in Localized Renal Cell Carcinoma.

Approximately 65% of renal cell carcinomas (RCC) are diagnosed at a localized stage. We investigated the chromosome 5q gain impact on disease-free survival (DFS) in RCC patients. Overall, 676 patients with stages 1-2 RCC and having cytogenetic analysis were included. Gain of 5q was observed in 108 patients, more frequently in clear cell (ccRCC) than non-clear cell tumors. Gain of 5q is likely an independent prognostic factor since the concerned patients had a decreased recurrence risk in stages 1-2 RCC, confirmed in multivariable analysis. Detecting 5q gain could enhance recurrence risk assessment, allowing tailored post-surgery surveillance, and reducing unnecessary treatments.

Factors Contributing to Computed Tomography Trauma Scan Times at a Tertiary Center: Improving Emergency Department Trauma Imaging Workflow Through Targeted Interventions.

PURPOSES: The aims of the study are to identify factors contributing to computed tomography (CT) trauma scan turnaround time variation and to evaluate the effects of an automated intervention on time metrics. METHODS: Throughput metrics were captured via picture archiving and communication system from January 1, 2018, to December 16, 2019, and included 17,709 CT trauma scans from our institution. Initial data showed that imaging technologist variation played a significant role in trauma imaging turnaround time. In December 2019, we implemented a 2-pronged intervention: (1) educational intervention to techs and (2) modified trauma CT abdomen/pelvis to autogenerate and autosend reformats to picture archiving and communication system. A total of 13,169 trauma CT scans were evaluated from the postintervention period taking place from January 2020 to March 2021. Throughput metrics such as last image to first report interval and emergency department length of stay were captured and compared with performing technologist, time of day, and weekday versus weekend scans. RESULTS: Substantial variability among trauma CT scans was observed. For CT trauma abdomen/pelvis, the interval from last image to initial report decreased from 26.4 to 24.0 minutes ( P = 0.001) while the interval between first and last image time decreased from 11.4 to 4.2 minutes ( P < 0.001). Emergency department length of stay also decreased from 3.9 to 3.7 hours ( P < 0.0001) in the postintervention period. Variation among imaging technologist was statistically significant and became less significant after intervention ( P = 0.09, P = 0.54). CONCLUSIONS: Factors such as imaging technologist variability, time of day, and day of the week of trauma scans played a significant role in CT trauma turnaround time variability. Automation interventions can help with efficiency in image turnaround time.

Ultrasound-guided transvaginal biopsies of pelvic lesions: diagnostic yield, safety profile, and technical considerations over a 20-year experience.

PURPOSE: To evaluate diagnostic yield, safety profile, and specific technical considerations of transvaginal ultrasound (TVUS) guided biopsy/aspiration. MATERIALS/METHODS: TVUS guided biopsy (core, FNA) procedures with pre-procedure CT/MRI imaging at a single institution between 2001 and 2021 were reviewed. Relevant patient demographic data was extracted via the Electronic Health Record (EMR), technical details of the biopsy procedure were collected, and distance to target via transvaginal and transabdominal biopsy approach was measured on pre-procedure imaging. Surgical pathology was reviewed and assessed for concordance. Complications were assessed. Statistical analysis was performed using SPSS. RESULTS: 96 TVUS procedures (mean age, 58.7 ± 15.2 years; mean BMI, 27.4) were reviewed. TVUS guided approach decreased the distance to target (mean, 1.1 cm vs 8.6 cm transabdominal; p < 0.0001) and created a safe path not otherwise available in two patients. Average lesion size was 4.0 ± 2.1 cm (IQR 2.5, 5.2 cm) and targets at or above the vaginal cuff (0.9 ± 1.5 cm) and up to 0.5 ± 1.0 cm above the acetabular roof were accessible. 75 (78%) cases were core biopsies (18G; median, 2 passes) and 21 were FNA. Conscious sedation was used in 84.4% (n = 81) of cases and local anesthetic was also used in 84.4% (n = 81) of cases. Overall diagnostic yield was 98.9% (n = 94) with 94.7% (n = 89) cases confirmed as concordant diagnoses, including 57.4% (n = 54) malignant. Complications occurred in eight patients (8.3%), all minor. No post-biopsy infections were encountered regardless of administration of pre-procedure antibiotics (n = 14, 14.6%,), documentation of sterile prep (n = 92, 95.8%), or speculum use (n = 19, 19.8%). 50% (n = 48) had a prior hysterectomy, with no association with adequacy or complications (p = 0.9). CONCLUSION: Transvaginal biopsy of pelvic lesions offers excellent diagnostic yield and favorable safety profile, and can dramatically decrease distance to target. CLINICAL RELEVANCE: Ultrasound-guided transvaginal approach offers a safe and effective way to biopsy pelvic lesions in women.

Radical Transurethral Resection of Bladder Tumor in Organ-confined Muscle-invasive Bladder Cancer: Yes!

Muscle-invasive bladder cancer is a potentially lethal disease often impacting elder and comorbid patients. Neoadjuvant chemotherapy followed by radical cystectomy is associated with morbidity and is an option that many patients refuse. Maximal transurethral resection of bladder tumor (TURBT) as part of a bladder preservation strategy can achieve surgical cure and may improve long-term recurrence-free survival. We encourage bladder preservation after maximal TURBT for appropriate patients.

Atypical sonographic presentation of diabetic mastopathy: A case report and literature review.

Diabetic fibrous mastopathy (DFM) is a relatively rare condition that most often occurs in insulin-dependent diabetics with a characteristic hypoechoic appearance on ultrasound (US). DFM frequently poses a diagnostic challenge in radiology due to malignant imaging similarities, and core needle biopsy is often required. If DFM is in the differential, fine-needle aspiration should not be considered as it will likely be non-diagnostic due to insufficient sampling and excisional biopsy should be avoided as it may worsen the disease process. Therefore, high clinical suspicion of DFM is important for diagnostic intervention consideration. We report the case of a 57-year-old who presented with a firm breast lump which on mammography was seen as a new 5.8 by 5.3 cm global asymmetry. US was performed and a diffuse area of increased echogenicity without posterior shadowing was identified. Given the appearance and patient history, DFM was considered unlikely. However, core needle biopsy revealed diabetic lymphocytic mastopathy consistent with DFM. Even though DFM is uncommon and has been reported to have a specific US appearance, it should be included in the differential for a palpable breast lump in any diabetic patient regardless of glucose control or atypical imaging findings.

Use of Complementary Alternative Medicine and Supplementation for Skin Disease.

Complementary alternative medicine (CAM) is a rapidly emerging field with prevalent use reported among dermatologic patients. However, the effectiveness and safety among different treatments notably varies. A review of the current literature regarding CAM for the treatment of 3 common conditions-atopic dermatitis (AD), psoriasis, and alopecia areata (AA)-is reported to help familiarize dermatologists with the most up-to-date information on this topic.

Relationship Between Mobile Digital Sensor Monitoring and Perioperative Outcomes: Systematic Review.

BACKGROUND: Monitoring surgical recovery has traditionally been confined to metrics measurable within the hospital and clinic setting. However, commercially available mobile sensors are now capable of extending measurements into a patient's home. As these sensors were developed for nonmedical applications, their clinical role has yet to be established. The aim of this systematic review is to evaluate the relationship between data generated by mobile sensors and postoperative outcomes. OBJECTIVE: The objective of this study is to describe the current use of mobile sensors in the perioperative setting and the correlation between their data and clinical outcomes. METHODS: A systematic search of EMBASE, MEDLINE, and Cochrane Library from inception until April 2019 was performed to identify studies of surgical patients monitored with mobile sensors. Sensors were considered if they collected patient metrics such as step count, temperature, or heart rate. Studies were included if patients underwent major surgery (≥1 inpatient postoperative day), patients were monitored using mobile sensors in the perioperative period, and the study reported postoperative outcomes (ie, complications and hospital readmission). For studies including step count, a pooled analysis of the step count per postoperative day was calculated for the complication and noncomplication cohorts using mean and a random-effects linear model. The Grading of Recommendations, Assessment, Development, and Evaluation tool was used to assess study quality. RESULTS: From 2209 abstracts, we identified 11 studies for review. Reviewed studies consisted of either prospective observational cohorts (n=10) or randomized controlled trials (n=1). Activity monitors were the most widely used sensors (n=10), with an additional study measuring temperature, respiratory rate, and heart rate (n=1). Low step count was associated with worse postoperative outcomes. A median step count of around 1000 steps per postoperative day was associated with adverse surgical outcomes. Within the studies, there was heterogeneity between the type of surgery and type of reported postoperative outcome. CONCLUSIONS: Despite significant heterogeneity in the type of surgery and sensors, low step count was associated with worse postoperative outcomes across surgical specialties. Further studies and standardization are needed to assess the role of mobile sensors in postoperative care, but a threshold of approximately 1000 steps per postoperative day warrants further investigation.

How Can We Help Alleviate the Financial Concerns of Non-Directed (Altruistic) Living Kidney Donors?

INTRODUCTION: The recent increase in non-directed donors (NDDs) in the United States (U.S.) may help reduce the overwhelming number of patients on the waitlist. However, non-directed donation may be limiting its full potential. Out-of-pocket donation costs upward of $8,000 may be a barrier to potential donors with altruistic tendencies, but inadequate financial support. This study aimed to describe the financial concerns of 31 U.S. NDDs. METHODS: We conducted qualitative interviews and administered quantitative demographic surveys between April 2013 and April 2015. Interview transcripts were analyzed using grounded theory techniques to describe and expand on themes relevant to the NDD experience. FINDINGS: We identified 4 sub-themes related to the theme of financial concerns: (1) direct costs related to transportation, lodging, and parking, (2) indirect costs of lost wages encountered from taking time off work to recover from surgery, (3) sources of financial support, and (4) suggestions for alleviating donor financial burden. Two thirds of participants (20) expressed concerns about direct and indirect donation costs. 11 NDDs reported the negative impact of direct costs,15 NDDs had concerns about indirect costs; only 7 donors received supplemental financial support from state mandates and transplant programs. DISCUSSION: Understanding the financial concerns of NDDs may guide improvements in the NDD donation experience that could support individuals who are interested in donating but lack the financial stability to donate. Removing financial disincentives may help increase nondirected donation rates, increase the living donor pool, and the number of kidneys available for transplantation.

Practices and Barriers in Sexual History Taking: A Cross-Sectional Study in a Public Adult Primary Care Clinic.

BACKGROUND: Surveys report low frequencies of sexual history (SH) obtained in primary care. Sexually transmitted infections incidence can be reduced with timely screening. It is important to determine whether providers obtain thorough SH and to identify needs for improvement. AIM: To evaluate the frequency and depth of SH taking in primary care. METHODS: In this cross-sectional cohort study, 1,017 primary care visits were reviewed (1,017 adult patients, female 55.26%). 417 patients were seen by male providers and 600 patients were seen by female providers. Multivariate ordered and logit models were deployed. MAIN OUTCOME MEASURES: The primary outcome measures included SH taking rates and completeness based on the 5 P model as described by the Centers for Disease Control and Prevention. RESULTS: All components of SH were explored in 1.08% of visits. Partial SH was obtained in 33.92% of visits. No SH was taken in the majority of visits (65%). SH was more likely to be taken from female patients than from male patients (P < .001), and was less likely to be obtained from older patients as compared to younger individuals (P < .001). There was no significant difference in SH taking between male and female providers (P = .753). The provider title and the level of training were found to be independent predictors of SH taking (P < .001). CLINICAL IMPLICATIONS: The results of this study highlight an unmet need for more comprehensive and consistent SH taking amongst providers, particularly in high-risk settings, so that SH can be used as a valuable tool in preventive care. STRENGTHS & LIMITATIONS: To the best of our knowledge, this is the largest study to date examining SH taking in the primary care setting. Limitations include the retrospective study design, lack of generalizability to other hospitals, and inconsistencies in available data. CONCLUSION: The SH taking rates in primary care clinics are globally low with a variation depending on the provider position or level of training, provider gender, and patient age.

Adjuvant Therapy for Localized High-Risk Renal Cell Carcinoma.

This article reviews the use of adjuvant therapies for prevention of recurrence following resection of clinically localized renal cell carcinoma (RCC). Clinical trials evaluating adjuvant therapy for RCC have focused primarily on the use of tyrosine kinase inhibitors and mammalian target of rapamycin inhibitors, which had improved outcome in patients with metastatic disease. However, all but 1 trial found no difference in disease-free survival in the adjuvant setting and none improved overall survival.

Local Tumor Bed Recurrence Following Partial Nephrectomy in Patients with Small Renal Masses.

PURPOSE: We examined the incidence, characteristics and treatment of patients with tumor bed recurrence after partial nephrectomy. MATERIALS AND METHODS: We retrospectively reviewed the charts of 2,256 patients with sporadic small renal masses treated with partial nephrectomy between 2000 and 2014. Local tumor bed recurrence was strictly defined as detection of a new enhancing lesion 1) specifically in the surgical defect or 2) in the same region (eg lower pole) as the partial nephrectomy site. To determine differences in multiple characteristics 44 patients (1.9%) with local recurrence were compared to 163 randomly selected patients who underwent partial nephrectomy with no recurrence. RESULTS: Patients with local tumor bed recurrence were more likely to have a solitary kidney (27% vs 4%, p <0.01) and bilateral disease at presentation (23% vs 10.4%, p = 0.02) compared to the group with no recurrence. Positive margins were found in 15.9% of local tumor bed recurrences compared to 3% of the control group (p <0.01). Median time between partial nephrectomy and the detection of local tumor bed recurrence was 23 months (range 2 to 107). Male gender, a solitary kidney at partial nephrectomy, positive surgical margins, multiple tumors, and higher nephrometry score and pathological stage were associated with local tumor bed recurrence. CONCLUSIONS: Local tumor bed recurrence after partial nephrectomy is associated with several preoperative factors, including multiple tumors and a solitary kidney, as well as intraoperative and postoperative factors such as a positive surgical margin and higher pathological stage.

Quantitative analysis of antimicrobial use on British dairy farms.

Antimicrobial resistance has been reported to represent a growing threat to both human and animal health, and concerns have been raised around levels of antimicrobial usage (AMU) within the livestock industry. To provide a benchmark for dairy cattle AMU and identify factors associated with high AMU, data from a convenience sample of 358 dairy farms were analysed using both mass-based and dose-based metrics following standard methodologies proposed by the European Surveillance of Veterinary Antimicrobial Consumption project. Metrics calculated were mass (mg) of antimicrobial active ingredient per population correction unit (mg/PCU), defined daily doses (DDDvet) and defined course doses (DCDvet). AMU on dairy farms ranged from 0.36 to 97.79 mg/PCU, with a median and mean of 15.97 and 20.62 mg/PCU, respectively. Dose-based analysis ranged from 0.05 to 20.29 DDDvet, with a median and mean of 4.03 and 4.60 DDDvet, respectively. Multivariable analysis highlighted that usage of antibiotics via oral and footbath routes increased the odds of a farm being in the top quartile (>27.9 mg/PCU) of antimicrobial users. While dairy cattle farm AMU appeared to be lower than UK livestock average, there were a selection of outlying farms with extremely high AMU, with the top 25 per cent of farms contributing greater than 50 per cent of AMU by mass. Identification of these high use farms may enable targeted AMU reduction strategies and facilitate a significant reduction in overall dairy cattle AMU.

Association of Distance to Treatment Facility With Survival and Quality Outcomes After Radical Cystectomy: A Multi-Institutional Study.

BACKGROUND: We sought to determine the effect of the travel distance on mortality and quality outcomes after radical cystectomy in a large multi-institutional cohort. PATIENTS AND METHODS: A total of 3957 patients who had undergone radical cystectomy for urothelial carcinoma at 6 North American tertiary care institutions were included. The association of travel distance with quality-of-care endpoints, 90-day mortality, and long-term survival were evaluated. RESULTS: The median patient age was 69 years (interquartile range, 61-76 years), and most patients were men (80%). Most patients had clinical stage T2 (45.2%) and T1 (24.7%) tumors. The median distance to the treatment facility was 102.9 miles (interquartile range, 24-271 miles). Patients residing in the first quartile of travel distance to treatment facility (< 24 miles) had lower usage of neoadjuvant chemotherapy compared with patients in the fourth distance quartile (adjusted odds ratio, 1.58; 95% confidence interval, 1.22-2.05; P = .001). Patients in the first distance quartile were also less likely to experience a delay in time to cystectomy (> 3 months) compared with patients with a greater travel distance (adjusted odds ratio, 0.673; 95% confidence interval, 0.532-0.851). Distance to the treatment facility was not associated with 90-day mortality or cancer-specific or all-cause mortality on multivariate analysis. CONCLUSION: Despite the potential health care disparities for bladder cancer patients residing distant to a regional surgical oncology facility, the study results suggest that the travel distance is not a barrier to appropriate oncologic care at regional tertiary care centers.

Assessing Symptom Burden in Bladder Cancer: An Overview of Bladder Cancer Specific Health-Related Quality of Life Instruments.

Background: A key component to monitoring and investigating patient QOL is through patient reported health related quality of life (HRQOL) outcome measures. Many instruments have been used to assess HRQOL in bladder cancer and each instrument varies in its development, validation, the context of its usage in the literature and its applicability to certain disease states. Objective: In this review, we sought to summarize how clinicians and researchers should most appropriately utilize the available HRQOL instruments for bladder cancer. Methods: We performed a comprehensive literature search of each instrument used in bladder cancer, paying particular attention to the outcomes assessed. We used these outcomes to group the available instruments into categories best reflecting their optimal usage by stage of disease. Results: We found 5 instruments specific to bladder cancer, of which 3 are validated. Only one of the instruments (the EORTC-QLQ-NMIBC24) was involved in a randomized, prospective validation study. The most heavily used instruments are the EORTC-QLQ-BLM30 for muscle-invasive disease and the FACT-Bl which is used across all disease states. Of the 5 available instruments, 4 are automatically administered with general instruments, while the BCI lacks modularity, and requires co-administration with a generalized instrument. Conclusion: There are multiple strong instruments for use in gauging HRQOL in bladder cancer patients. We have divided these instruments into three categories which optimize their usage: instruments for use following NMIBC treatments (EORTC-QLQ-NMIBC24), instruments for use following radical cystectomy (FACT-Bl-Cys and EORTC-QLQ-BLM30) and more inclusive instruments not limited by treatment modality (BCI and FACT-Bl).

The Future of Enhanced Recovery for Radical Cystectomy: Current Evidence, Barriers to Adoption, and the Next Steps.

Radical cystectomy (RC) is a complex procedure that can involve long postoperative hospital stays and complicated, burdensome recoveries. Enhanced recovery after surgery is a broad term encompassing an overall approach to perioperative management of postsurgical patients and is becoming more widely accepted for cystectomy patients. This review examines the current evidence for using enhanced recovery protocols for RC as well as current rates of adoption of enhanced recovery among urologists performing RC. We also discuss the next steps for overcoming barriers to the widespread implementation of enhanced recovery for RC.
