- Abstract
The I21 beamline at Diamond Light Source is dedicated to advanced resonant inelastic X-ray scattering (RIXS) for probing charge, orbital, spin and lattice excitations in materials across condensed matter physics, applied sciences and chemistry. Both the beamline and the RIXS spectrometer employ divergent variable-line-spacing gratings covering a broad energy range of 280-3000 eV. A combined energy resolution of ∼35 meV (16 meV) is readily achieved at 930 eV (530 eV) owing to the optimized optics and the mechanics. Considerable efforts have been paid to the design of the entire beamline, particularly the implementation of the collection mirrors, to maximize the X-ray photon throughput. The continuous rotation of the spectrometer over 150° under ultra high vacuum and a cryogenic manipulator with six degrees of freedom allow accurate mappings of low-energy excitations from solid state materials in momentum space. Most importantly, the facility features a unique combination of the high energy resolution and the high photon throughput vital for advanced RIXS applications. Together with its stability and user friendliness, I21 has become one of the most sought after RIXS beamlines in the world., (open access.)

- Abstract
Purpose: Currently, functional magnetic resonance imaging (fMRI) is the most commonly used technique for obtaining dynamic information about the brain. However, because of the complexity of the data, it is often difficult to directly visualize the temporal aspect of the fMRI data. Approach: We outline a t -distributed stochastic neighbor embedding (t-SNE)-based postprocessing technique that can be used for visualization of temporal information from a 4D fMRI data. Apart from visualization, we also show its utility in detection of major changes in the brain meta-states during the scan duration. Results: The t-SNE approach is able to detect brain-state changes from task to rest and vice versa for single- and multitask fMRI data. A temporal visualization can also be obtained for task and resting state fMRI data for assessing the temporal dynamics during the scan duration. Additionally, hemodynamic delay can be quantified by comparison of the detected brain-state changes with the experiment paradigm for task fMRI data. Conclusion: The t-SNE visualization can visualize help identify major brain-state changes from fMRI data. Such visualization can provide information about the degree of involvement and attentiveness of the subject during the scan and can be potentially utilized as a quality control for subject's performance during the scan., (© 2021 Society of Photo-Optical Instrumentation Engineers (SPIE).)

- Abstract
Purpose: Through the last three decades, functional magnetic resonance imaging (fMRI) has provided immense quantities of information about the dynamics of the brain, functional brain mapping, and resting-state brain networks. Despite providing such rich functional information, fMRI is still not a commonly used clinical technique due to inaccuracy involved in analysis of extremely noisy data. However, ongoing developments in deep learning techniques suggest potential improvements and better performance in many different domains. Our main purpose is to utilize the potentials of deep learning techniques for fMRI data for clinical use. Approach: We present one such synergy of fMRI and deep learning, where we apply a simplified yet accurate method using a modified 3D convolutional neural networks (CNN) to resting-state fMRI data for feature extraction and classification of Alzheimer's disease (AD). The CNN is designed in such a way that it uses the fMRI data with much less preprocessing, preserving both spatial and temporal information. Results: Once trained, the network is successfully able to classify between fMRI data from healthy controls and AD subjects, including subjects in the mild cognitive impairment (MCI) stage. We have also extracted spatiotemporal features useful for classification. Conclusion: This CNN can detect and differentiate between the earlier and later stages of MCI and AD and hence, it may have potential clinical applications in both early detection and better diagnosis of Alzheimer's disease., (© 2020 Society of Photo-Optical Instrumentation Engineers (SPIE).)

- Abstract
Background: Comparative efficacy of same-day bowel preparations for colonoscopy remains unclear., Aims: A meta-analysis of randomized controlled trials comparing the efficacy of same-day versus split dose bowel preparations for colonoscopy., Methods: A systematic search was conducted in MEDLINE, clinicaltrials.gov, Cochrane Registry, EMBASE, SCOPUS, Web of Science and CINAHL. Studies were gathered using keywords: "morning preparation", "morning bowel preparation", "same day bowel preparation", and "colonoscopy." Pooled estimates of bowel preparation quality were analyzed among studies with categorical and continuous outcomes according to relative risk (RR) or mean difference (MD). A random effects model was chosen a priori for all analyses., Results: A total of 1216 studies were retrieved with 15 trials meeting inclusion criteria. The categorical outcome of high quality bowel preparation for any same-day bowel preparation versus any split preparation was no different with a RR 0.95 [0.90;1.00] (P=0.62). Adenoma detection rate (ADR) was not different between groups, RR 0.97 [0.79;1.20] (P=0.81). Willingness to repeat and tolerability did not differ (RR 1.14 [0.96,1.36] (P=0.14) and RR 1.00 [0.96;1.04] (P=0.98), respectively. Adverse events were similar except for bloating, which was less frequent among the same-day preparation group, RR 0.68 [0.40;0.94] (P=0.02)., Conclusion: No clinically significant differences were noted among recipients of same day or split dose regimens. Adenoma detection rate, willingness to repeat and tolerability were similar, but bloating and interference with sleep favored the same-day preparations. Given lack of clinical differences, patient preference should dictate timing of colonoscopy preparation.

- Abstract
A description of the technical and design details of a scanning four-bounce crystal monochromator that has recently been commissioned for the Versatile X-ray Absorption Spectroscopy (XAS) beamline at Diamond Light Source is presented. This device consists of two independent rotary axes of unique design which are synchronized using a multiple read-head encoder system. This monochromator is shown to be capable of maintaining the flux throughput of the Bragg axes without the need of any external feedback mechanism from 4 to 20 keV. The monochromator is currently equipped with cryogenically cooled crystals with the upstream axis consisting of two independent Si(111) crystals and a pair of channel-cut crystals in the downstream axis. The possibility of installing an additional Si(311) crystal-set to extend the energy range to 34 keV is incorporated into the preliminary design of the device. Experimental data are presented showing the exceptional mechanical stability and repeatability of the monochromator axes., (open access.)

- Abstract
Objectives: To study the relationship between health literacy (HL) and socioeconomic, demographic factors and disease-specific illness beliefs among patients who present to the emergency department with heart failure (HF)., Background: Maintenance of well-being for patients with HF is partially dependent on appropriate self-care behaviors, which, in turn, are influenced by underlying illness beliefs. HL is a potential modifier of the interaction between behaviors and beliefs. There have been limited investigations studying this relationship among individuals with acute HF., Methods: A cross-sectional study of patients with hemodynamically stable acute HF was conducted. Demographic, education, and social support data were obtained from all patients along with self-reported responses to the 36-item STOFHLA survey, a 14 item HF-specific illness belief questionnaire, and a 5-item self-care adherence survey. General association was assessed using the χ or Fisher exact test, and comparisons were made using the Kruskal-Wallis test., Results: A total of 100 patients (51 females and 49 males) were included, 94% of whom were African-American (mean age [SD]: 57.5 [13.2] years). Inadequate, marginal, and adequate health literacy were present in 35%, 17%, and 48%, respectively, with increasing adequacy among the higher educated (P < 0.001). Overall, HF illness beliefs were considered to be "inaccurate" (mean score [SD] on a 4-point Likert scale: 2.8 [0.3]) but did correlate positively with improved HL (r = 0.26; P = 0.008)., Conclusion: In this cohort of relatively young, predominantly African-American patients with acute HF, HL was positively correlated with level of education and negatively associated with age and was an important determinant of disease-specific illness beliefs.

- Abstract
Background: A seven-item cancer-specific fall risk tool (Cleveland Clinic Capone-Albert [CC-CA] Fall Risk Score) was shown to have a strong concordance index for predicting falls; however, validation of the model is needed., Objectives: The aims of this study were to validate that the CC-CA Fall Risk Score, made up of six factors, predicts falls in patients with cancer and to determine if the CC-CA Fall Risk Score performs better than the Morse Fall Tool., Methods: Using a prospective, comparative methodology, data were collected from electronic health records of patients hospitalized for cancer care in four hospitals. Risk factors from each tool were recorded, when applicable. Multivariable models were created to predict the probability of a fall. A concordance index for each fall tool was calculated., Findings: The CC-CA Fall Risk Score provided higher discrimination than the Morse Fall Tool in predicting fall events in patients hospitalized for cancer management.

- Abstract
Objective: To investigate the impact of pelvic radiation on survival in patients with uterine serous carcinoma (USC) who received adjuvant chemotherapy., Methods: Patients with stage I-IV USC were identified from the Surveillance, Epidemiology, and End Results program 2000 to 2009. Patients were included if treated with surgery and chemotherapy. Patients were divided into two groups: those who received chemotherapy and pelvic radiation therapy (CT_RT) and those who received chemotherapy only (CT). Kaplan-Meier curves and Cox regression proportional hazard models were used., Results: Of the 1,838 included patients, 1,272 (69%) were CT and 566 (31%) were CT_RT. Adjuvant radiation was associated with significant improvement in overall survival (OS; p<0.001) and disease-specific survival (DSS; p<0.001) for entire cohort. These findings were consistent for the impact of radiation on OS (p<0.001) and DSS (p<0.001) in advanced stage (III-IV) disease but not for early stage (I?II) disease (p=0.21 for OS and p=0.82 for DSS). In multivariable analysis adjusting for age, stage, race and extent of lymphadenectomy, adjuvant radiation was a significant predictor of OS and DSS for entire cohort (p=0.003 and p=0.05) and in subset of patients with stage III (p=0.02 and p=0.07) but not for patients with stage I (p=0.59 and p=0.49), II (p=0.83 and p=0.82), and IV USC (p=0.50 and p=0.96). Other predictors were stage, positive cytology, African American race and extent of lymphadenectomy., Conclusion: In USC patients who received adjuvant chemotherapy, adjuvant radiation was associated with significantly improved outcome in stage III disease but not for other stages. Positive cytology, extent of lymphadenectomy and African race were significant predictors of outcome.

- Abstract
Background/Aims . To compare long-term fertility and bleeding outcomes of women who underwent robotic-assisted, laparoscopic, and abdominal myomectomy at our institution over a 15-year period. Methods . This was a retrospective cohort study of myomectomy patients 18-39 years old that had surgery between January 1995 and December 2009 at our institution. Long-term follow-up on fertility and bleeding outcomes was collected from the patient directly. The uterine fibroid symptom and quality of life survey was also administered to assess current bleeding patterns. Baseline characteristics were compared across groups. Univariable comparisons of fertility and bleeding outcomes based on surgical approach were made using analysis of variance, Kruskal-Wallis analysis of ranks, and Chi-square tests as appropriate. Results . 134/374 (36%) subjects agreed to participate in the study. 81 subjects underwent an open procedure versus 28 and 25 subjects in the laparoscopic and robotic groups, respectively. Median follow-up after surgery was 8 years. 50% of patients desired pregnancy following surgery and, of those, 60% achieved spontaneous pregnancy; the spontaneous pregnancy rate did not differ between groups. Additionally, UFS-QOL scores and/or subscores did not differ between groups. Conclusion . There is no significant difference in long-term bleeding or fertility outcomes in robotic-assisted, laparoscopic, or abdominal myomectomy., Competing Interests: The authors report no conflict of interests.

- Abstract
Background: Cardiac (123)I-metaiodobenzylguanidine ((123)I-mIBG) imaging improves prognostication in patients with left ventricular (LV) dysfunction. Whether (123)I-mIBG can identify optimal candidates for implantable cardiac defibrillator (ICD) placement is unclear. We examined whether (123)I-mIBG enhances risk assessment and identifies patients with enhanced survival with ICD in a patient cohort with reduced LV function who were candidates for ICD implantation., Methods and Results: We identified 777 patients (66 sites, 12 countries) without ICD at the time of enrollment in Adreview Myocardial Imaging for Risk Evaluation in Heart Failure (ADMIRE-HF) and index (123)I-mIBG study. Patients completed prescribed study protocol and follow-up. Heart-to-mediastinum (H/M) ratio was determined from (123)I-mIBG results. Survival modeling used a Cox proportional hazards mixed-effects model, including a propensity score, to adjust for nonrandomized ICD implantation after (123)I-mIBG. All-cause death occurred in 75 patients (9.6%), and 196 (25%) patients had ICD implantation on follow-up. After adjusting for multiple factors, although the H/M ratio added incremental prognostic value and enhanced reclassification, neither H/M results, BNP levels, nor left ventricular ejection fraction interacted with ICD use in the survival model, indicating that these variables did not identify patients with enhanced survival with ICD implantation. Nonetheless, H/M results did identify the number of lives saved by ICD use per 100 treated., Conclusions: We found that although (123)I-mIBG imaging enhances the risk stratification of patients with left ventricular dysfunction who are ICD candidates, it does not identify which patients may have improved survival with ICD placement. However, (123)I-mIBG identifies the absolute benefit gained with ICD use, thus may play a role in optimizing the cost-effectiveness of this intervention., Clinical Trial Registration: URL: http://www.clinicaltrials.gov.

- Abstract
To compare conventional minimally invasive (MIS) approaches and newer technology approaches in women undergoing hysterectomy for benign disease. PubMed was searched for all pertinent randomized-controlled trials (RCTs). Selected outcomes were compared using standard meta-analysis methods. Three RCTs compared conventional MIS to robotic-assisted hysterectomy and 5 RCTs compared conventional laparoscopy to single-incision hysterectomy. There were no significant differences in outcomes. A subanalysis comparing conventional to robotic-assisted laparoscopy found an association between conventional laparoscopy and shorter operative time. Newer technology approaches do not confer an advantage over conventional MIS approaches in women undergoing hysterectomy for benign disease.

- Abstract
Objectives: To investigate whether patients with germline BRCA1/2 mutations who received neoadjuvant chemotherapy (NAC) for advanced-stage Müllerian cancer (MC) have an improved outcome compared to patients who did not undergo genetic testing., Methods: Three hundred and two patients who received NAC for stage III-IV MC were identified from a multi-institutional study involving Cleveland Clinic and Brigham and Women's Hospital for 2000-2014 and 2010-2014 respectively. Patients were divided into 3 cohorts: patients with germline BRCA1/2 mutations (BRCA_mut+; N=30), patients with no genetic testing (BRCA_mut_unk; N=166) and patients with negative genetic testing (BRCA_mut-, N=106)., Results: There were no differences in the clinical characteristics and rates of complete cytoreduction and bowel resection between the three groups. BRCA_mut+ had longer PFS compared to BRCA_mut_unk and BRCA_mut- (19.1 vs. 15.1 vs. 15.7months respectively. However, this difference was not statistically significant (p=0.48). Patients with BRCA2 mutation had non-significant trend toward longer PFS compared to patients with unknown BRCA or BRCA1 mutation (20.2 vs. 15.1 vs. 14.8months respectively, p=0.58). BRCA_mut+ and BRCA_mut- had longer overall survivals (OS) compared to BRCA_mut_unk patients (50.5 vs. 54.1 vs. 36.5months respectively, p=0.009). In multivariable analyses, controlling for age, stage and complete cytoreduction, BRCA_mut_unk was associated with worse PFS (HR 1.44, 95% CI 1.01-2.05, p=0.045) and OS (HR 2.67, 95% CI 1.33-5.36, p=0.006)., Conclusions: Patients with germline BRCA mutations had improved outcomes with NAC compared to patients with unknown BRCA status. These outcomes were more favorable compared to the outcome of NAC in prior studies., (Copyright © 2015 Elsevier Inc. All rights reserved.)

- Abstract
The design and implementation of a compact and portable sample alignment system suitable for use at both synchrotron and free-electron laser (FEL) sources and its performance are described. The system provides the ability to quickly and reliably deliver large numbers of samples using the minimum amount of sample possible, through positioning of fixed target arrays into the X-ray beam. The combination of high-precision stages, high-quality sample viewing, a fast controller and a software layer overcome many of the challenges associated with sample alignment. A straightforward interface that minimizes setup and sample changeover time as well as simplifying communication with the stages during the experiment is also described, together with an intuitive naming convention for defining, tracking and locating sample positions. The setup allows the precise delivery of samples in predefined locations to a specific position in space and time, reliably and simply.

- Abstract
Background: Fatigue affects 40% to 50% of all PD patients and is a leading cause of disability, with no clearly established or efficacious established treatments., Methods: In this double-blinded, placebo-controlled, pilot trial, we investigated whether rasagiline improved fatigue among PD patients. Subjects were randomized to 1 mg daily of rasagiline or placebo for 12 weeks. The primary endpoint was a change in the Modified Fatigue Impact Scale from baseline to week 12., Results: Thirty PD subjects (16 men), with Modified Fatigue Impact Scale baseline score of 67 ± 15, were randomized (16 to rasagiline vs. 14 to placebo). Significant improvement was noted in the mean Modified Fatigue Impact Scale score of the rasagiline group (12 points) as compared to placebo (8.5 points) from baseline to week 12 (P = 0.003)., Conclusion: In this pilot study, rasagiline at a dose of 1 mg per day improved fatigue. Larger randomized studies are needed to confirm this finding., (© 2015 International Parkinson and Movement Disorder Society.)

- Abstract
Objectives: Advances in laparoscopy have demonstrated that supraumbilical primary ports can be desirable in complex cases with large masses. This study evaluated distances to vital retroperitoneal vasculature that were encountered with 45- and 90-degree angle entry from the umbilicus and 2 commonly described supraumbilical entry points at 3 and 5 cm cephalad from the umbilicus., Study Design: Retrospective analysis of computed tomography scans of the abdomen and pelvis from 100 randomly selected women who were 18-50 years old with normal anatomy was performed. Three-dimensional models of sagittal sections were generated using IMPAX software. Measurements from the abdominal wall at the umbilicus and 3 and 5 cm cephalad with 45- and 90-degree angles to retroperitoneal structures were performed., Results: With 90-degree angle entry, the abdominal wall thickness (AWT) was thinnest at the umbilicus; however, the thickness at 3 and 5 cm was similar. AWT increased at all sites with 45-degree angle entry, and the same pattern was observed. AWT and intraperitoneal distance positively correlated with body mass index and supraumbilical entry points. With 90-degree angle entry, the aorta was 1.9 cm (95% confidence interval [CI], 1.4-2.4) and 2.5 cm (95% CI, 2.0-2.9) farther away at 3 and 5 cm cephalad compared with umbilical entry. In one-third of the cases, regardless of port placement, a vascular structure other than the aorta was the most anterior vessel. With 45-degree angle entry at the umbilicus, no vessels were encountered. With 45-degree angle entry at 3 and 5 cm cephalad, the aorta was the most anterior vessel in 1% and 2% of cases, respectively, and was noted to be 1.0 cm (95% CI, 1.0-1.0) and 2.3 cm (95% CI, 1.2-3.3) farther away than with 90-degree angle entry. A vessel other than the aorta was encountered in 4% and 7% of cases at 3 and 5 cm, respectively., Conclusion: According to theoretic modeling, supraumbilical primary port placement can be implemented safely in laparoscopy. With supraumbilical entry, the distance to retroperitoneal vessels was greater than at the umbilicus. Compared with a 90-degree angle, with a 45-degree angle entry, it was uncommon to encounter vasculature, and all measured distances were greater., (Copyright © 2015 Elsevier Inc.

Kaplan-Meier curves and logistic regression models were used., Results: One hundred forty-eight women were identified. Of them, 25.7% had LNM (21.7% pelvic LNM, 18.5% para-aortic LNM). Among patients with LNM who had both pelvic and para-aortic lymphadenectomy, isolated pelvic, para-aortic and both LNM were noted in 51.4%, 17.1%, and 31.4% respectively. Age and depth of myometrial invasion were significant predictors of LNM in LVSI positive EC. Node positive patients had high recurrence rate (47% vs. 11.8%, p<0.05) especially distant (60.9% vs. 7.9%, p<0.001) and para-aortic (13.2% vs. 1.8%, p=0.017) recurrences compared to node negative EC. LNM was associated with lower progression-free survival (p=0.002) but not overall survival (p=0.73)., Conclusion: EC with positive LVSI is associated with high risk of LNM. LNM is associated with high recurrence rate especially distant and para-aortic recurrences. Adjuvant treatments should target prevention of recurrences in these areas.

- Abstract
Objective: To investigate the role of CA-125 percent reduction after neoadjuvant chemotherapy in predicting the extent of the interval debulking surgery (IDS) and outcomes in patients with advanced-stage müllerian carcinoma., Methods: Patients who received neoadjuvant chemotherapy for advanced-stage müllerian carcinoma from 2000 to 2013 were identified. Percent reduction in CA-125 was categorized into 2 groups: ≥ 90% (CA ≥ 90%) and <90% (CA < 90%) reduction from prechemotherapy to preoperative CA-125., Results: Of the 115 patients identified, 73% had CA ≥ 90% and 27% had CA < 90%. Optimal and complete IDS were achieved in 87% and 38%, respectively. Compared with the CA < 90% group, the CA ≥ 90% group was more likely to have complete IDS (P = 0.035), less likely to have a bowel resection (P < 0.001), and more likely to have no viable tumor/microscopic disease with treatment effect (P < 0.001). No difference in overall survival (OS; P = 0.81) and progression-free survival (PFS; P = 0.60) was noted between the groups. In multivariable analysis, CA ≥ 90% was not a predictor of PFS (hazard ratio [HR], 1.08; 95% confidence interval [CI], 0.65-1.79; P = 0.77) or OS (HR, 1.45; 95% CI, 0.73-2.9; P = 0.29). Patients with preoperative CA-125 < 20 had significantly longer OS (P = 0.05) and PFS (P = 0.005) than did those with preoperative CA-125 ≥ 20. In multivariable analysis, preoperative CA-125 < 20 was a predictor of PFS (HR, 0.37; 95% CI, 0.20-0.66; P < 0.001) but not OS (HR, 0.64; 95% CI, 0.34-1.21; P = 0.17)., Conclusions: A reduction in CA-125 of at least 90% is associated with complete IDS, favorable pathologic response, and fewer bowel resections. A preoperative CA-125 < 20 suggests improved outcome. These findings are helpful for treatment planning and patient counseling.

- Abstract
Objective: To evaluate the effect of adding bevacizumab to adjuvant paclitaxel and carboplatin and as maintenance on progression-free survival (PFS) in advanced or recurrent endometrial carcinoma (EMCA)., Methods: A phase II trial was conducted in patients with measurable disease. Paclitaxel (175mg/m(2)/3h), carboplatin (AUC 5) and bevacizumab (15mg/kg) were administered q 21 days. Patients with a complete response after 6-8cycles received maintenance therapy with bevacizumab 15mg/kg q 21 days for 16cycles. Based on GOG 177 which had a 6-month PFS rate of 59%, an increase in 6-month PFS to 72% with the treatment regimen was considered of clinical interest., Results: 15 patients were enrolled on protocol when accrual to the study was discontinued due to the initiation of a national randomized phase II trial. A total of 127 courses (median 8, range 1-20) of carboplatin, paclitaxel, and bevacizumab combination therapy were administered. One patient suffered a bowel perforation after her first course of therapy and was inevaluable for response. Fourteen of the 15 patients (93%, 95% CI: 82-100) were progression free at 6months. The median follow-up was 36months (7-58+). The median PFS was 18months (CI: 11-25). Five complete responses and 6 partial responses were seen for an overall response rate of 73% (CI: 45-91). The median overall survival was 58months (CI: 48-68)., Conclusions: The bevacizumab, paclitaxel, and carboplatin regimen is active and tolerable in advanced and recurrent EMCA. Its impact awaits results of the recently completed randomized phase II trial., (Copyright © 2014 Elsevier Inc. All rights reserved.)

- Abstract
Study Objective: To compare resident, fellow, and attending urologic and gynecologic surgeons' musculoskeletal and mental strain during laparoscopic and robotic sacrocolpopexy., Design: Prospective cohort study (Canadian Task Force classification II-2)., Setting: Academic medical center., Patients: Patients who underwent robotic or laparoscopic sacrocolpopexy from October 2009 to January 2011., Interventions: The Body Part Discomfort (BPD) survey was completed before cases, and the National Aeronautics and Space Administration Task Load Index and BPD survey were completed after cases. Higher scores on BPD and the National Aeronautics and Space Administration Task Load Index indicate greater musculoskeletal discomfort and mental strain. BPD scores were averaged over the following body regions: head/neck, back, hand/wrist, arms, and knees/ankles/feet. Changes in body region-specific discomfort scores were the primary outcomes., Measurements and Main Results: Multivariable analysis was performed using mixed-effects linear regression with surgeon as a random effect. Sixteen surgeons participated (53% fellows, 34% residents, and 13% attendings). Thirty-three robotic and 53 laparoscopic cases were analyzed, with a median surgical time of 231 minutes (interquartile range, 204-293 minutes) versus 227 minutes (interquartile range, 203-272 minutes; p = .31), a median estimated blood loss of 100 mL (interquartile range, 50-175 mL) versus 150 mL (interquartile range, 50-200 mL; p = .22), and a mean patient body mass index of 27 ± 4 versus 26 ± 4 kg/m(2) (p = .26), respectively. Robotic surgeries were associated with lower neck/shoulder (-0.19 [interquartile range, -0.32 to -0.01], T = -2.49) and back discomfort scores (-0.35 [interquartile range, -0.58 to 0], T = -2.38) than laparoscopic surgeries. Knee/ankle/foot and arm discomfort increased with case length (0.18 [interquartile range, 0.02-0.3], T = 2.81) and (0.07 [interquartile range, 0.01-0.14], p = .03), respectively., Conclusion: Surgeons performing minimally invasive sacrocolpopexy experienced less neck, shoulder, and back discomfort when surgery was performed robotically., (Copyright © 2015 AAGL.
