RESUMEN
BACKGROUND: Changes in surgical technique and postoperative care that target improvements in functional outcomes are widespread in the literature. Radical prostatectomy (RP) is one such procedure that has seen multiple advances over the past decade. The objective of this study was to leverage RP as an index case to determine whether practice changes over time produced observable improvements in patient-reported outcomes. METHODS: This study analyzed patients undergoing RP by experienced surgeons at a tertiary care center with prospectively maintained patient-reported outcome data from 2008 to 2019. Four patient-reported urinary function outcomes at 6 and 12 months after RP were defined with a validated instrument: good urinary function (domain score ≥ 17), no incontinence (0 pads per day), social continence (≤1 pad per day), and severe incontinence (≥3 pads per day). Multivariable logistic regressions evaluated changes in outcomes based on the surgical date. RESULTS: Among 3945 patients meeting the inclusion criteria, excellent urinary outcomes were reported throughout the decade but without consistent observable improvements over time. Specifically, there were no improvements in good urinary function at 12 months (P = .087) based on the surgical date, and there were countervailing effects on no incontinence (worsening; P = .005) versus severe incontinence (improving; P = .003). Neither approach (open, laparoscopic, or robotic), nor nerve sparing, nor membranous urethral length mediated changes in outcomes. CONCLUSIONS: In a decade with multiple advances in surgical and postoperative care, there was evidence of improvements in severe incontinence, but no measurable improvements across 3 other urinary outcomes. Although worsening disease factors could contribute to the stable observed outcomes, a more systematic approach to evaluating techniques and implementing patient selection and postoperative care advances is needed. LAY SUMMARY: Although there have been advances in radical prostatectomy over the past decade, consistent observable improvements in postoperative incontinence were not reported by patients. To improve urinary function outcomes beyond the current high standard, the approach to studying innovations in surgical technique needs to be changed, and further development of other aspects of prostatectomy care is needed.

PURPOSE: Adolescent idiopathic scoliosis (AIS) is a deformity of the spine that results in external asymmetry of the torso in the shoulder, waist, and rib hump. Several patient reported outcome measures (PROMS) including the Trunk Appearance Perception Scale (TAPS) and SRS-22r self-image domain are used to measure the patient's self-perception. The purpose of this study is to investigate the relationship between objective surface topographic measurements of the torso to subjective patient self-perception. METHODS: 131 AIS subjects and 37 controls participated in this study. All subjects completed TAPS and SRS-22r PROMS followed by whole body 3d surface topographic scanning. An automated analysis pipeline was used to compute 57 measurements. Multivariate linear models were developed to predict TAPS and SRS-22r self-image using each unique combination of 3 parameters and leave one out validation where the best combinations were selected. RESULTS: Back surface rotation, waist crease vertical asymmetry and rib prominence volume were most predictive of TAPS. The final predicted TAPS values from leave one out cross validation was correlated to ground truth TAPS scores with an R value of 0.65. Back surface rotation, silhouette centroid deviation, and shoulder normal asymmetry were most predictive of SRS-22r self-image with a correlation of R = 0.48. CONCLUSION: Surface topographic measurements of the torso are correlated to TAPS and SRS-22r self-image scores in AIS patients and controls, with TAPS exhibiting a stronger relationship, better reflecting the patient's external asymmetries.

Background: Adolescent idiopathic scoliosis results in three dimensional changes to a patient's body, which may change a patient's range of motion. Surface topography is an emerging technology to evaluate three dimensional parameters in patients with scoliosis. The goal of this paper is to introduce novel and reliable surface topographic measurements for the assessment of global coronal and sagittal range of motion of the spine in adolescents, and to determine if these measurements can distinguish between adolescents with lumbar scoliosis and those without scoliosis. Methods: This study is a retrospective cohort study of a prospectively collected registry. Using a surface topographic scanner, a finger to floor and lateral bending scans were performed on each subject. Inter- and intra-rater reliabilities were assessed for each measurement. ANOVA analysis was used to test comparative hypotheses. Results: Inter-rater reliability for lateral bending fingertip asymmetry (LBFA) and lateral bending acromia asymmetry (LBAA) displayed poor reliability, while the coronal angle asymmetry (CAA), coronal angle range of motion (CAR), forward bending finger to floor (FBFF), forward bending acromia to floor (FBAF), sagittal angle (SA), and sagittal angle normalized (SAN) demonstrated good to excellent reliability. There was a significant difference between controls and lumbar scoliosis patients for LBFA, LBAA, CAA and FBAF (p-values < 0.01). Conclusion: Surface topography yields a reliable and rapid process for measuring global spine range of motion in the coronal and sagittal planes. Using these tools, there was a significant difference in measurements between patients with lumbar scoliosis and controls. In the future, we hope to be able to assess and predict perioperative spinal mobility changes.
RESUMEN
Axial twisting of the spine has been previously shown to be affected by scoliosis with decreased motion and asymmetric twisting. Existing methods for evaluating twisting may be cumbersome, unreliable, or require radiation exposure. In this study, we present an automated surface topographic measurement tool to evaluate global axial rotation of the spine, along with two measurements: twisting range of motion (TROM) and twisting asymmetry index (TASI). The aim of this study is to evaluate the impact of scoliosis on axial range of motion. Adolescent idiopathic scoliosis (AIS) patients and asymptomatic controls were scanned in a topographic scanner while twisting maximally to the left and right. TROM was significantly lower for AIS patients compared to control patients (69.1° vs. 78.5°, p = 0.020). TASI was significantly higher for AIS patients compared to control patients (29.6 vs. 19.8, p = 0.023). After stratifying by scoliosis severity, both TROM and TASI were significantly different only between control and severe scoliosis patients (Cobb angle > 40°). AIS patients were then divided by their major curve region (thoracic, thoracolumbar, or lumbar). ANOVA and post hoc tests showed that only TROM is significantly different between thoracic AIS patients and control patients. Thus, we demonstrate that surface topographic scanning can be used to evaluate twisting in AIS patients.
RESUMEN
Purpose: We implemented an advanced practice provider (APP)-led clinic to aid in managing the growing population of men on active surveillance (AS) for prostate cancer. Our objective was to evaluate the quality and safety of an established APP-led AS clinic by comparing outcomes with urologist-led biopsies, defined in terms of adherence to scheduled visits and biopsy complications. Materials and Methods: We performed a retrospective review of 2341 consecutive patients treated in an AS clinic at a high-volume referral center between 2000-2019. We examined the rate of no-show or same-day cancellation of visits for APPs versus urologists and compared the risk of biopsy complications between these providers. Generalized estimating equations were used to account for repeated visits and biopsies. Results: There were significantly more no-shows at APP visits (odds ratio [OR] 1.40, 95% confidence interval [CI] 1.16-1.70, p <0.001); however, this only amounted to one no-show every 41 visits. There was no evidence of increased biopsy complications with APPs (OR 0.37, 95% CI 0.05-2.49, p =0.3). Patients were not prospectively assigned to APP or urologist management; therefore, unmeasured patient differences could bias our results. Conclusions: We demonstrated that in an established APP-led AS clinic at a high-volume center, APPs achieved acceptable patient adherence to scheduled visits and biopsy complications. Because patients were not continuously managed by one type of provider, further prospective studies are needed to establish equivalent pathologic outcomes in APP-managed AS.
