A prospective, controlled multisite trial of yoga in pediatric inflammatory bowel disease.

AIM: To investigate whether a structured yoga program improves health-related quality of life (HRQOL) and self-efficacy in pediatric patients receiving care for inflammatory bowel disease (IBD). METHODS: IBD patients who were 10-17 years old participated in a 12 week, in-person yoga intervention at two clinical sites. Outcomes were measured at time of consent (T0), start of yoga (T1), and completion of yoga (T2) and 3 months after yoga completion (T3) using the IMPACT-III, Pediatric Quality of Life Inventory (PedsQL), and General Self Efficacy (GSE) scales. RESULTS: Seventy-eight patients were enrolled. Fifty-six patients completed nine or more classes. 73.2% had Crohn's disease and 26.8% ulcerative colitis or IBD-unclassified. A significant increase in IMPACT-III was seen from T1 to T3 (mean change of 5.22, SD = 14.33, p = 0.010), in the PedsQL (mean change = 2.3, SD = 10.24, p = 0.050), and GSE (mean change = 1, SD = 3.60, p = 0.046). 85.2% of patients reported yoga helped them to control stress. Long-term data was available for 47 subjects with 31.9% (n = 15) continuing to practice yoga one to 3 years after study completion. CONCLUSION: This structured 12-week yoga program showed significant improvements in HRQOL and general self-efficacy, particularly 3 months after classes were concluded suggesting that yoga's benefits may persist. Yoga is a safe and effective adjunct to standard medical care to improve QOL and self-efficacy in youth with IBD.

Reducing Anxiety Among Nurse Leaders Through Virtual Animal-Related Engagement.

This project explored the relationship between virtual animal-related engagement (ARE) and anxiety in nurse leaders. A quality improvement project used a valid and reliable visual analog scale from 0 to 100 for self-reporting of anxiety in nurse leaders. Baseline and intervention group data were collected for 2 weeks at 15 and 5 minutes before the daily leadership huddle. Differences in anxiety levels 5 minutes before the huddle for baseline with the use of the intervention were significant. Within the intervention group, anxiety levels at 15 and 5 minutes were significant. Project outcomes suggest a difference in self-reported anxiety of nurse leaders based on ARE.

Impact of a COPD care bundle on hospital readmission rates.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is one of the leading causes of mortality worldwide and contributes considerably to morbidity and health care costs. In October 2014, the Centers for Medicare and Medicaid Services introduced financial penalties followed by bundled payments for care improvement initiatives in patients hospitalized with COPD. OBJECTIVES: This study seeks to evaluate whether an evidence-based interprofessional COPD care bundle focused on inpatient, transitional, and outpatient care would reduce hospital readmission rates. METHODS: A pre- and postintervention analysis comparing readmission rates after a hospitalization for COPD in subjects who received standard of care versus an interprofessional team-led COPD care bundle was conducted. The primary outcome was 30-day all-cause readmissions; secondary outcomes included 60- and 90-day all-cause readmissions, escalation of pharmacotherapy, interprofessional interventions, and hospital length of stay. RESULTS: A total of 189 subjects were included in the control arm and 127 subjects in the COPD care bundle arm. A reduction in 30-day all-cause readmissions between the control arm and COPD care bundle arm (21.7% vs. 11.8%, P = 0.017) was seen. Similar outcomes were seen in 60-day (18% vs. 8.7%, P = 0.013) and 90-day all-cause readmissions (19.6% vs. 4.7%, P < 0.001). Pharmacists consulted with 68.5% of subjects and assisted with access to outpatient medications in 45.7% of subjects in the COPD care bundle arm. An escalation in maintenance therapy occurred more often in the COPD care bundle arm (22.2% vs. 44.9%, P < 0.001) than the control arm. CONCLUSIONS: An interprofessional team-led COPD care bundle resulted in significant reductions in all-cause hospital readmissions at 30, 60, and 90 days.

Decreasing Hospital Readmissions Utilizing an Evidence-Based COPD Care Bundle.

PURPOSE: Chronic obstructive pulmonary disease (COPD) is a chronic condition that leads to significant morbidity and mortality. Management of COPD hospitalizations utilizing an evidence-based care bundle can provide consistent quality of care and may reduce readmissions. METHODS: This single-center retrospective cohort study evaluated readmission rates in patients hospitalized with a COPD exacerbation. Patients in the pre-intervention cohort received usual care, while patients in the post-intervention cohort received an innovative inpatient COPD care bundle. The bundle focused on optimizing care in five areas: consults, inpatient interventions, education, transitions of care, and after discharge care. RESULTS: In this study, 149 subjects were included in the pre-intervention cohort and 214 subjects were included in the post-intervention cohort. Thirty-day readmission rates were lower in the post-intervention cohort compared to the pre-intervention cohort, 22.4% vs. 38.3% (p = 0.001). A reduction in 60-day and 90-day readmission rates was also observed, 13.7% vs. 40.3% (p < 0.001) and 10.1% vs. 32.2% (p < 0.001), respectively. CONCLUSION: Bundled care is an effective and inexpensive method for institutions to provide consistent and quality care. The findings of this study demonstrate that the implementation of a COPD care bundle is an effective strategy to decrease hospital readmissions.

The effect of inpatient addiction screening and intervention on readmissions.

AIM: The number of individuals in the United States (US) needing treatment for substance use disorder (SUD) but not receiving treatment at a specialty facility was reported to be almost 18 million in 2019. This study measured the difference in subsequent hospital visits between groups, one receiving screening, brief intervention, and referral to treatment (SBIRT) and one receiving usual care. BACKGROUND: There are studies that discuss SBIRT in terms of process evaluation, staff training, reduced readmission rates, and self-reported reductions in substance use. However, the interrelationship between components of SBIRT implementation, such as feasibility, cost, and sustainability need additional investigation. This study compared readmissions between groups receiving SBIRT counseling (n = 101) and those receiving usual care (n = 99). RESULTS: The overall total number of subsequent visits for SUD for the group receiving SBIRT (53) was significantly lower than for the group receiving usual care (128). The overall total number of non-SUD subsequent visits was not significantly different between groups. The study also identified differences between sexes that require further investigation. CONCLUSIONS: The findings of this study demonstrate a measure of difference based on SBIRT intervention. The SBIRT program can be incorporated into daily practice in the acute care setting through nursing education and utilization of the electronic health platform.

A urinary catheter valve is non-inferior to continuous bladder drainage with respect to post-operative UTIs: a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: Urinary tract infections (UTIs) are common with indwelling catheter use. Our primary aim was to compare UTI rates in women sent home after surgery with continuous bladder drainage versus a urinary catheter valve. METHODS: This was a non-inferiority prospective randomized controlled study between June 2016 to June 2019. Women who were being discharged home with a Foley catheter following urogynecologic surgery due to urinary retention were randomized to a continuous urinary drainage bag or a urinary catheter valve. The primary outcome of this study was post-operative UTI rates within 30 days of surgery. The secondary outcome was patient satisfaction, as determined by a Foley satisfaction questionnaire. RESULTS: Out of 97 women, 51 were randomized to continuous drainage and 46 to the urinary catheter valve. Comparing UTI rates, the urinary catheter valve (32.6%) was non-inferior to the continuous urinary drainage bag (33.3%). The upper bound of the 95% CI was less than the predetermined non-inferiority margin (difference 0.7%, 95% CI: -0.195, 0.180), and therefore non-inferiority criteria were met. Patients were more satisfied with the urinary catheter valve than with the continuous drainage bag (p ≤ 0.001). CONCLUSIONS: Use of this urinary catheter valve increased patient satisfaction without affecting the post-operative UTI rate. This easy and inexpensive device could help patients have a better catheter experience and should be considered in women being discharged home with a urinary catheter.

Obtaining Vitamin D Levels in Children With Fractures Improves Supplementation Compliance.

BACKGROUND: Obtaining ideal serum 25-vitamin D (25VitD) levels (>30 ng/mL) is imperative in childhood to achieve peak bone mass. Supplementation compliance in children recommended to take vitamin D postfracture was evaluated. The questions we sought to answer were: Is there (1) a compliance difference between patients with known versus unknown 25VitD levels; (2) an association between compliance and age; and (3) an association between fracture severity and initial 25VitD level. METHODS: One physician analyzed compliance in 1818 fracture patients 2 to 18 years (42% female) with known (48%) and unknown 25VitD. Patient/caregiver's self-reported adherence to supplementation as "yes" (4 d/wk minimum) or "no" defined compliance. Compliance relating to fracture severity via Abbreviated Injury Scale (AIS), 25VitD level, and age, was analyzed. RESULTS: Patients with 25VitD levels were more compliant than patients without (61%, n=532/872; 21%, n=206/946; P<0.001). In total, 83% (n=104/125) of AIS 3 patients were compliant, compared with 49% (n=628/1292) of AIS 1/2 patients (P<0.001). Compliance increased with age (odds ratio: 1.09, 95% confidence interval: 1.061-1.120, P<0.001). CONCLUSIONS: Compliance increased when 25VitD levels were obtained, improving with fracture severity. Clinicians should order 25VitD levels on fracture patients to improve supplementation compliance. LEVEL OF EVIDENCE: This is a level IV prognostic study which aims to investigate the effects of various patient characteristics on compliance.

Stoma Bridge Types and Their Impact on Patient Outcomes: A Retrospective Analysis and Prospective Global Survey of Surgical Practice.

PURPOSE: The purpose of this study was to describe the effect of rigid or flexible stoma bridges used for loop ostomy diversions on peristomal skin integrity. Additional aims were to describe surgeon practices related to stoma bridges, and determine the availability of an ostomy nurse specialist. DESIGN: Retrospective chart review and cross-sectional survey. SAMPLE AND SETTING: The sample used to address the first aim (effect of stoma bridges) comprised 93 adult patients cared for at Morristown Medical Center, Atlantic Health System, Morristown, New Jersey, an acute care facility. Data provided by 355 colorectal surgeons from 30 countries were used to describe surgeon practice in this area and determine the availability of an ostomy nurse specialist. Respondents were invited from an international roster of colorectal surgeons obtained with permission from the American Society of Colon and Rectal Surgeons (ASCRS). METHODS: In order to accomplish the initial aim, we retrospectively reviewed medical records of patients who underwent ostomy surgery from 2008 to 2015 and met inclusion criteria. In order to meet our additional aims, analyzed data were obtained from a survey of colorectal surgeons that queried practices related to stoma bridges, and availability of an ostomy nurse specialist. RESULTS: Patients managed with a rigid bridge were significantly more likely to experience leakage beneath the pouching system faceplate than were patients managed by a flexible bridge (42% vs 11%, P < .001). Slightly less than one quarter of patients who developed leakage (n = 22, 24%) experienced pressure and moisture-related peristomal skin complications. Peristomal wounds, inflammation, and infection were significantly higher when a rigid bridge was used (χ test, P < .003). The surgeon's survey (N = 355) showed variability in the use of bridges. Ninety-three percent of all surgeons indicated an ostomy nurse specialist was part of their health care team. CONCLUSIONS: Rigid ostomy bridges were associated with a higher likelihood of leakage from underneath the faceplate of the pouching system and impaired peristomal skin integrity. Analysis of colorectal surgeon responses to a survey indicated no clear consensus related to bridge use in patients undergoing loop ostomies.

Demonstration of anatomical development of the human macula within the first 5 years of life using handheld OCT.

PURPOSE: To demonstrate the anatomical development of the human macula using handheld spectral domain optical coherence tomography (SD-OCT) during the first 5 years of life. METHODS: This study is a cross-sectional, observational case series. Thirty-five normal eyes of 35 full-term/late preterm infants and children under 5 years of age were included. Handheld SD-OCT was used to image the macula of each eye. The data were analyzed using the Duke OCT Retinal Analysis Program v17 software. Retinal thickness maps were generated for the total retinal thickness (TRT), the inner retinal layers thickness (IRL), and the photoreceptor layer thickness (PRL). Based on the early treatment diabetic retinopathy study macular map, average thickness measurements were taken at 4 circles centered on the fovea (diameter): the foveal center (0.5 mm), sector 1 (S1) (1 mm), sector 2 (S2) (3 mm), sector 3 (S3) (6 mm). RESULTS: The median age at participation was 24 months (range 5-52 months). The TRT increased throughout the first 5 years of life, and this increase was statistically significant at the foveal center and S1 (p = 0.01, p = 0.016, respectively). The IRL did not show any significant change in thickness from birth and throughout the first 5 years of life. The PRL thickness showed thickening in the first 24 months of age at the foveal center and S1 which was statistically significant at S1 (p = 0.066, p = 0.016, respectively). Interestingly, this PRL thickness increase plateaus beyond 24 months of age. The photoreceptors inner segment/outer segment (IS/OS) band was identified as a distinct layer in all our subjects. CONCLUSION: Our findings conform with the literature that the anatomical development of the macular IRL completes before 5 months of age and hence before the PRL. We also identify 24 months of age as an important developmental milestone for photoreceptors development in the human macula.

Age-Specific Sex Differences in Magnetic Resonance Imaging-Depicted Carotid Intraplaque Hemorrhage.

BACKGROUND AND PURPOSE: Stroke rates are higher in men compared with women in the fourth through seventh decades of life, and higher rates may result from differences in carotid intraplaque hemorrhage (IPH), an unstable atherosclerotic plaque component. We report age-specific sex differences in the presence of magnetic resonance imaging-depicted carotid IPH. METHODS: Patients (n=1115) underwent magnetic resonance imaging for carotid IPH between 2005 and 2014. Low-grade carotid stenosis patients (n=906) without prior endarterectomy were eligible for this cross-sectional study. RESULTS: Of the 906 patients included (mean age±SD in years, 66.98±15.15), 63 (6.95%) had carotid IPH. In men and women, carotid IPH was present in 11.43% (48 of 420) and 3.09% (15 of 486), respectively (P<0.0001). Multivariable logistic regression analysis confirmed greater odds of carotid IPH in men for all ages: 45 to 54 (odds ratio=45.45; 95% confidence interval, 3.43-500), 55 to 64 years (odds ratio=21.74; 95% confidence interval, 3.21-142.86), 65 to 74 years (odds ratio=10.42; 95% confidence interval, 2.91-37.04), and ≥75 years (odds ratio=5.00; 95% confidence interval, 2.31-10.75). Male sex modified the effect of age on the presence of carotid IPH (ß=0.074; SE=0.036; P=0.0411). CONCLUSIONS: Men have greater age-specific odds of magnetic resonance imaging-depicted carotid IPH compared with women. With increasing age post-menopause, the odds of carotid IPH in women becomes closer to that of men. Delayed onset of carotid IPH in women, an unstable plaque component, may partly explain differential stroke rates between sexes, and further studies are warranted.

The Role of the Supplementary Motor Region in Overt Reading: Evidence for Differential Processing in SMA-Proper and Pre-SMA as a Function of Task Demands.

A differentiation in function between the pre-SMA (i.e., cognitive load) and the SMA-proper (i.e., motor execution) has been described (Zhang et al., Cereb Cortex 22:99-111, 2012). These differential SMA functions may be influential in overt reading tasks. The present study examined the relationships between various segments of the SMA and overt reading through the modulation of task demands in an effort to explore the complexity of the print-to-speech network. Skilled reading adults (N = 15) took part in five overt reading tasks: pure regular word reading, pure exception word reading, mixed regular word and exception word reading, go/no-go reading with nonword foils and go/no-go reading with pseudohomophone foils. Five regions of interest that spanned the pre-SMA to the SMA-proper were isolated. Behaviour-function relationships were tested to examine the associations between performance (response time) and brain activity (percent signal change). Further, the coherence between feedforward (SMA) and feedback (supramarginal gyrus) regions were explored to further refine the print-to-speech network. We found that the pre-SMA was related to cognitively demanding tasks (go/no-go with pseudohomophones), whereas the SMA-proper was related to an automatized task (pure regular words). Notably, only those tasks that required information from the feedback system (i.e., mixed word lists, go/no-go tasks) showed connections between SMA regions and the supramarginal gyrus, which is in line with the role of feedback and feedforward systems in the print-to-speech network. Together, these results support the notion that the pre-SMA and SMA-proper are sensitive to reading tasks that differentially invoke higher cognitive resources (mixed word lists, go/no-go) versus automatized articulation (pure lists), respectively. We discuss our findings in the context of print-to-speech neural networks.

Drusen Volume and Retinal Pigment Epithelium Abnormal Thinning Volume Predict 2-Year Progression of Age-Related Macular Degeneration.

PURPOSE: To analyze the value of novel measures of retinal pigment epithelium-drusen complex (RPEDC) volume to predict 2-year disease progression of intermediate age-related macular degeneration (AMD). DESIGN: Prospective, observational study. PARTICIPANTS: Three hundred forty-five AMD and 122 non-AMD participants enrolled in the Age Related Eye Disease Study 2 Ancillary Spectral-Domain (SD) Optical Coherence Tomography (OCT) study. METHODS: High-density SD OCT macular volumes were obtained at yearly study visits. The RPEDC abnormal thickening (henceforth, OCT drusen) and RPEDC abnormal thinning (RAT) volumes were generated by semiautomated segmentation of total RPEDC within a 5-mm-diameter macular field. MAIN OUTCOME MEASURES: Volume change and odds ratio (OR) with 95% confidence intervals (CI) for progression to advanced AMD with choroidal neovascularization (CNV) or central geographic atrophy (GA). RESULTS: Complete volumes were obtained in 265 and 266 AMD eyes and in 115 and 97 control eyes at baseline and at year 2, respectively. In AMD eyes, mean (standard deviation) OCT drusen volume increased from 0.08 mm(3) (0.16 mm(3)) to 0.10 mm(3) (0.23 mm(3); P < 0.001), and RAT volume increased from 8.3 × 10(-4) mm(3) (20.8 × 10(-4) mm(3)) to 18.4 × 10(-4) mm(3) (46.6 × 10(-4) mm(3); P < 0.001). Greater baseline OCT drusen volume was associated with 2-year progression to CNV (P = 0.002). Odds of developing CNV increased by 31% for every 0.1-mm(3) increase in baseline OCT drusen volume (OR, 1.31; 95% CI, 1.06-1.63; P = 0.013). Greater baseline RAT volume was associated with significant 2-year increase in RAT volume (P < 0.001), noncentral GA (P < 0.001), and progression to central GA (P < 0.001). Odds of developing central GA increased by 32% for every 0.001-mm(3) increase in baseline RAT volume (OR, 1.32; 95% CI, 1.14-1.53; P < 0.001). In non-AMD eyes, all volumes were significantly lower than AMD eyes and showed no significant 2-year change. CONCLUSIONS: Macular OCT drusen and RAT volumes increased significantly in AMD eyes over 2 years. These quantitative SD OCT biomarkers predict 2-year AMD progression and may serve as useful biomarkers for future clinical trials.

Optical Coherence Tomography Reflective Drusen Substructures Predict Progression to Geographic Atrophy in Age-related Macular Degeneration.

PURPOSE: Structural and compositional heterogeneity within drusen comprising lipids, carbohydrates, and proteins have been previously described. We sought to detect and define phenotypic patterns of drusen heterogeneity in the form of optical coherence tomography-reflective drusen substructures (ODS) and examine their associations with age-related macular degeneration (AMD)-related features and AMD progression. DESIGN: Retrospective analysis in a prospective study. PARTICIPANTS: Patients with intermediate AMD (n = 349) enrolled in the multicenter Age-Related Eye Disease Study 2 (AREDS2) ancillary spectral-domain optical coherence tomography (SD OCT) study. METHODS: Baseline SD OCT scans of 1 eye per patient were analyzed for the presence of ODS. Cross-sectional and longitudinal associations of ODS presence with AMD-related features visible on SD OCT and color photographs, including drusen volume, geographic atrophy (GA), and preatrophic features, were evaluated for the entire macular region. Similar associations were also made locally within a 0.5-mm-diameter region around individual ODS and corresponding control region without ODS in the same eye. MAIN OUTCOME MEASURES: Preatrophy SD OCT changes and GA, central GA, and choroidal neovascularization (CNV) from color photographs. RESULTS: Four phenotypic subtypes of ODS were defined: low reflective cores, high reflective cores, conical debris, and split drusen. Among the 349 participants, there were 307 eligible eyes and 74 (24%) had at least 1 ODS. The ODS at baseline were associated with (1) greater macular drusen volume at baseline (P < 0.001), (2) development of preatrophic changes at year 2 (P = 0.001-0.01), and (3) development of macular GA (P = 0.005) and preatrophic changes at year 3 (P = 0.002-0.008), but not development of CNV. The ODS at baseline in a local region were associated with (1) presence of preatrophy changes at baseline (P = 0.02-0.03) and (2) development of preatrophy changes at years 2 and 3 within the region (P = 0.008-0.05). CONCLUSIONS: Optical coherence tomography-reflective drusen substructures are optical coherence tomography-based biomarkers of progression to GA, but not to CNV, in eyes with intermediate AMD. Optical coherence tomography-reflective drusen substructures may be a clinical entity helpful in monitoring AMD progression and informing mechanisms in GA pathogenesis.

Validation of Macular Choroidal Thickness Measurements from Automated SD-OCT Image Segmentation.

PURPOSE: Spectral domain optical coherence tomography (SD-OCT) imaging permits in vivo visualization of the choroid with micron-level resolution over wide areas and is of interest for studies of ocular growth and myopia control. We evaluated the speed, repeatability, and accuracy of a new image segmentation method to quantify choroid thickness compared to manual segmentation. METHODS: Two macular volumetric scans (25 × 30°) were taken from 30 eyes of 30 young adult subjects in two sessions, 1 hour apart. A single rater manually delineated choroid thickness as the distance between Bruch's membrane and sclera across three B-scans (foveal, inferior, and superior-most scan locations). Manual segmentation was compared to an automated method based on graph theory, dynamic programming, and wavelet-based texture analysis. Segmentation performance comparisons included processing speed, choroid thickness measurements across the foveal horizontal midline, and measurement repeatability (95% limits of agreement (LoA)). RESULTS: Subjects were healthy young adults (n = 30; 24 ± 2 years; mean ± SD; 63% female) with spherical equivalent refractive error of -3.46 ± 2.69D (range: +2.62 to -8.50D). Manual segmentation took 200 times longer than automated segmentation (780 vs. 4 seconds). Mean choroid thickness at the foveal center was 263 ± 24 µm (manual) and 259 ± 23 µm (automated), and this difference was not significant (p = 0.10). Regional segmentation errors across the foveal horizontal midline (±15°) were ≤9 µm (median) except for nasal-most regions closest to the nasal peripapillary margin-15 degrees (19 µm) and 12 degrees (16 µm) from the foveal center. Repeatability of choroidal thickness measurements had similar repeatability between segmentation methods (manual LoA: ±15 µm; automated LoA: ±14 µm). CONCLUSIONS: Automated segmentation of SD-OCT data by graph theory and dynamic programming is a fast, accurate, and reliable method to delineate the choroid. This approach will facilitate longitudinal studies evaluating changes in choroid thickness in response to novel optical corrections and in ocular disease.

Catheter-based intramural delivery of red blood cells in an animal model of atherosclerosis.

This report demonstrates intramural red blood cell (RBC) delivery in an atherosclerotic rabbit aorta model and validates the ability of fluoroscopy and computed tomography to verify RBC deposition. A microinfusion catheter with a 35-gauge needle delivered RBCs mixed with iodinated contrast agent to the aorta wall. Six rabbits were sacrificed after injection to confirm RBC delivery. Iron deposition was examined in four additional rabbits 3-7 weeks after injection. Imaging demonstrated 86% sensitivity and 100% specificity for the detection of RBC deposition (n = 25 injection attempts). Iron deposits were found in all intraplaque injection sites 3-7 weeks after injection.

Retinal atrophy in eyes with resolved papilledema detected by optical coherence tomography.

BACKGROUND: To apply automated spectral domain optical coherence tomography (SD-OCT) segmentation to eyes with resolving papilledema. METHODS: Ninety-four patients with idiopathic intracranial hypertension seen at the Duke Eye Center neuro-ophthalmology clinic between November 2010 and October 2011 were reviewed. Excluded were eyes with papilledema with Frisén grade >2, other optic neuropathies or retinopathies, and those that did not have SD-OCT imaging. The remaining 43 patients were split into 2 groups: non-atrophic papilledema and atrophic papilledema. Automated SD-OCT segmentation was performed on patients with non-atrophic papilledema and age-matched controls for each of the 9 regions of the Early Treatment Diabetic Retinopathy Study map. Bonferroni correction was used for multiple comparisons. All SD-OCT scans were reviewed for retinal structural abnormalities. RESULTS: Total macular thickness was significantly thinner within the fovea and inner macular ring in non-atrophic papilledema vs control eyes (266 vs 276 µm, P = 0.04; 333 vs 344 µm P < 0.01, n = 26 non-atrophic papilledema, 30 controls). SD-OCT demonstrated thinning within the fovea, inner macular ring, and outer macular ring of the outer plexiform layer plus nuclear layer in non-atrophic papilledema vs control (124 vs 131 µm, P < 0.01; 112 vs 118 µm, P = 0.03; 95 vs 100 µm, P = 0.03). Retinal structural changes were seen in 21/33 eyes with atrophic papilledema vs none of the eyes with non-atrophic papilledema or controls. CONCLUSIONS: SD-OCT shows qualitative and quantitative changes in the macula of eyes with resolved papilledema.

Quantitative classification of eyes with and without intermediate age-related macular degeneration using optical coherence tomography.

OBJECTIVE: To define quantitative indicators for the presence of intermediate age-related macular degeneration (AMD) via spectral-domain optical coherence tomography (SD-OCT) imaging of older adults. DESIGN: Evaluation of diagnostic test and technology. PARTICIPANTS AND CONTROLS: One eye from 115 elderly subjects without AMD and 269 subjects with intermediate AMD from the Age-Related Eye Disease Study 2 (AREDS2) Ancillary SD-OCT Study. METHODS: We semiautomatically delineated the retinal pigment epithelium (RPE) and RPE drusen complex (RPEDC, the axial distance from the apex of the drusen and RPE layer to Bruch's membrane) and total retina (TR, the axial distance between the inner limiting and Bruch's membranes) boundaries. We registered and averaged the thickness maps from control subjects to generate a map of "normal" non-AMD thickness. We considered RPEDC thicknesses larger or smaller than 3 standard deviations from the mean as abnormal, indicating drusen or geographic atrophy (GA), respectively. We measured TR volumes, RPEDC volumes, and abnormal RPEDC thickening and thinning volumes for each subject. By using different combinations of these 4 disease indicators, we designed 5 automated classifiers for the presence of AMD on the basis of the generalized linear model regression framework. We trained and evaluated the performance of these classifiers using the leave-one-out method. MAIN OUTCOME MEASURES: The range and topographic distribution of the RPEDC and TR thicknesses in a 5-mm diameter cylinder centered at the fovea. RESULTS: The most efficient method for separating AMD and control eyes required all 4 disease indicators. The area under the curve (AUC) of the receiver operating characteristic (ROC) for this classifier was >0.99. Overall neurosensory retinal thickening in eyes with AMD versus control eyes in our study contrasts with previous smaller studies. CONCLUSIONS: We identified and validated efficient biometrics to distinguish AMD from normal eyes by analyzing the topographic distribution of normal and abnormal RPEDC thicknesses across a large atlas of eyes. We created an online atlas to share the 38 400 SD-OCT images in this study, their corresponding segmentations, and quantitative measurements.

Comparing Postoperative Urinary Retention Rates Between Robotic Apical Prolapse Repairs.

IMPORTANCE: Understanding the risk of urinary retention with different prolapse repair surgical procedures is important for perioperative counseling. OBJECTIVE: The study compared postoperative urinary retention rates between robotic sacrocolpopexy and robotic uterosacral ligament suspension. STUDY DESIGN: This institutional review board-exempt retrospective cohort study compared patients who underwent pelvic organ prolapse repair with robotic sacrocolpopexy (RSCP) and robotic uterosacral ligament suspension (RUSLS) between June 2018 and March 2022. Our primary outcome was the rate of acute postoperative urinary retention (POUR) in these groups. Secondary outcomes were the number of days needed to resolve urinary retention and persistent voiding dysfunction. RESULTS: Out of 298 patients, 258 underwent RSCP and 40 underwent RUSLS. Acute POUR was found in 73 patients (24%): 46 patients (18%) in the RSCP group versus 26 patients (65%) in the RUSLS group (P < 0.001). Multivariate analysis demonstrated a significantly higher rate of acute POUR after RUSLS (odds ratio [OR] = 17.92, confidence interval [CI] = 3.06-104.86; P = 0.001). Patients with an elevated preoperative postvoid residual volume >100 mL or concomitant midurethral sling were more likely to develop POUR (OR = 2.93, CI = 1.43-5.98; P = 0.003 and OR = 2.19, CI = 1.16-4.14; P = 0.016, respectively). While patients with higher parity were less likely to have urinary retention (OR = 0.71, CI = 0.53-0.96; P = 0.024), age, body mass index, prolapse stage, and concurrent posterior repair did not affect the urinary retention rate significantly. The number of days needed to resolve POUR and persistent voiding dysfunction were similar. CONCLUSIONS: Acute POUR appears more likely to develop after RUSLS compared to RSCP. Elevated preoperative postvoid residual volume and concomitant midurethral sling surgery independently increase the risk of POUR.

Progression of intermediate age-related macular degeneration with proliferation and inner retinal migration of hyperreflective foci.

PURPOSE: Drusen and migrating retinal pigment epithelium have been associated with hyperreflective foci (HF) detected by spectral-domain optical coherence tomography (SD-OCT). This study sought to quantify the change in intraretinal HF distribution and its correlation with age-related macular degeneration (AMD) disease progression. DESIGN: Prospective observational study from the multicenter Age-Related Eye Disease Study 2 (AREDS2) Ancillary SD-OCT Study. PARTICIPANTS: Patients (n=299) with 1 enrolled eye with intermediate AMD and baseline SD-OCT, followed by SD-OCT imaging at 1-year and 2-year visits. METHODS: The number and location of HF were scored in SD-OCT scans of all 299 eyes. The change in transverse (horizontal) and axial (vertical) distribution of HF in the macula were evaluated with pairwise signed-rank tests. Two-year inner retinal HF migration was determined by the change in HF-weighted axial distribution (AxD) score calculated for each eye. The correlation of HF with SD-OCT features of AMD progression was evaluated with logistic regression analysis. MAIN OUTCOME MEASURES: The mean change in number of HF, transverse and axial distribution of HF in the macula, and AxD per eye. RESULTS: In 299 study eyes, the 2-year increase in the number of HF (P<0.001) and the AxD (P<0.001) per eye represented longitudinal proliferation and shift to inner retinal layers, respectively. Eyes with geographic atrophy (GA) at 2 years were correlated with the presence of baseline HF (P<0.001; odds ratio [OR], 4.72; 95% confidence interval [CI], 2.43-9.80), greater number of baseline HF (P<0.001; OR, 1.61 per HF; 95% CI, 1.32-2.00), and greater baseline AxD (P<0.001; OR, 1.58 per AxD point; 95% CI, 1.29-1.95). CONCLUSIONS: Proliferation and inner retinal migration of SD-OCT HF occurred during follow-up in eyes with intermediate AMD. These characteristics were associated with greater incidence of GA at year 2; therefore, SD-OCT HF proliferation and migration may serve as biomarkers for AMD progression.

A Case Manager-Led Pneumonia Care Bundle in a Subacute Rehabilitation Facility.

PURPOSE OF THE STUDY: To evaluate the relationship between a case manager-led pneumonia care bundle at skilled nursing facilities (SNFs) and 30-day hospital readmissions for pneumonia. PRIMARY PRACTICE SETTINGS: The primary practice settings included patients hospitalized with pneumonia at 2 community hospitals between October 2018 and June 2019 and who were subsequently transferred to an SNF. METHODOLOGY AND SAMPLE: A retrospective cohort study was completed comparing patients in the preintervention cohort who received pneumonia standard of care versus patients in the postintervention cohort who received a case manager-led evidence-based pneumonia care bundle at an SNF. From October 2018 to June 2019, patients admitted with pneumonia to 2 community hospitals in Northwest New Jersey were enrolled in the preintervention cohort. Patients admitted with pneumonia from January 2020 to June 2021 were enrolled in the postintervention group. The primary outcome was to reduce 30-day readmission rates for all patients discharged from the hospital to an SNF with pneumonia. RESULTS: Ninety-nine patients were enrolled in the preintervention cohort and 34 patients were enrolled in the postinterventions cohort. Thirty-day readmission rates were lower in the postintervention cohort (24.2% vs. 17.7%). This reduction in readmission rates was clinically significant, demonstrating a 27% reduction for all patients discharged from the hospital to an SNF with pneumonia. IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Individualized pneumonia self-management education can be easily implemented in SNFs to improve quality-of-care outcomes for patients. Our health care system collaborates with several SNFs to decrease 30-day hospital readmission. The pneumonia care bundle includes specific measures to improve the transition of care for patients with pneumonia by decreasing the variability of patient care after discharge from the hospital to an SNF. It was hypothesized that to decrease readmissions from the SNFs, we needed to address the quality of care provided by the SNFs by using a 2-prong approach; education of SNF staff on the pneumonia care bundle, and in-person weekly follow-up visits in the SNF until discharge from the SNF to the patient's home.
