2020-Current year OA Pubs

PURPOSE: Same-day surgery (SDS) cancellations have significant implications on patients and hospitals. This study aimed to identify demographic and socioeconomic factors that impact SDS cancellations across a single pediatric health system.

METHODS: A case-control retrospective review captured patients (age < 18) who underwent SDS procedures from July 2022 to August 2024. Patients were included if they underwent any procedure at three operative sites: a tertiary pediatric academic hospital (PAH) and two outpatient surgery centers (OSC). Patients whose SDS was cancelled (n = 2,034) were compared to those whose surgeries proceeded as scheduled (n = 25,573). Patient zip codes were matched to Child Opportunity Index (COI) 2.0 data.

RESULTS: The overall SDS cancellation rate was 7.37 %, with a significantly higher rate observed at the PAH compared to OSC (11.4 % vs 53 %, p < 0.001). Patients with cancelled cases were more likely to identify as Black and have the lowest quintile COI (p < 0.001). Cancelled in preop and no shows were two reasons with the most racial disparities. In a sub-analysis comparing cancelled cases between operating sites, PAH cancelled patients tended to be Black (23.8 % vs 11.7 %, p < 0.001) and have very low COI (20.1 % vs. 10.6 %, p < 0.001).

CONCLUSION: SDS cancellation rates are significantly higher amongst patients who identify as Black and reside in low opportunity neighborhoods. Disparities in cancellation rate are more significant in patients scheduled at the urban PAH compared …

Inter-brain synchrony (IBS), measured by hyperscanning, refers to the synchronization of multiple individuals' brain activities during social interactions. Traditional fNIRS-based hyperscanning suffers shortcomings like low spatial resolution and high susceptibility to superficial interference, causing imprecise estimation of IBS in complex social tasks. This study aims to fill the knowledge gap by comprehensively assessing diffuse optical tomography (DOT), an enhanced alternative to fNIRS, can benefit hyperscanning studies of complex social interactions. Sixteen dyads were engaged in both collaborative and individual tangram puzzle tasks, and their brain activities were recorded simultaneously using DOT and fNIRS. We found that DOT demonstrated significantly stronger …

Mouse Alport Podocytes Are Susceptible To Aav9 Transduction In Vivo, Meei-Hua Lin, Kohei Omachi, Joshua F Begin, Jennifer L Richardson, Jeffrey H Miner

2020-Current year OA Pubs

INTRODUCTION: Alport syndrome features a defective glomerular basement membrane (GBM) due to variants in COL4A3, COL4A4, and COL4A5. The most severe forms, which lack the GBM's collagen α3α4α5(IV) network, progress from hematuria in early childhood to proteinuria, chronic kidney disease, and kidney failure by the age of ∼30. As a monogenic disease without specific treatments, and with podocytes being the only glomerular cells that synthesize collagen α3α4α5(IV), the ability to efficiently deliver genes to Alport podocytes could open up new possibilities for treatment.

METHODS: As a proof-of-concept study, we investigated whether podocytes in X-linked Alport mice were susceptible to transduction …

Methods and analysis: STRONG-MS is a codesigned, clinician-led, single-blind, randomised controlled trial evaluating the effect of a HiRIT programme, ONERO, on HRQoL for people with MS. Secondary aims include assessing changes in bone mineral density, body composition, …


Robust And Interpretable Medical Image Segmentation Via Retrieval And Mechanistic Analysis, Salma Ahmed Jan 2026

Robust And Interpretable Medical Image Segmentation Via Retrieval And Mechanistic Analysis, Salma Ahmed

Theses and Dissertations (Comprehensive)

Medical image segmentation is a critical component of clinical decision-making, yet deep learning based segmentation models face persistent challenges. These models typically require large volumes of densely annotated data, exhibit strong sensitivity to domain shifts across scanners and patient populations, and lack explicit anatomical priors. Furthermore, despite continual architectural advances beyond fully convolutional networks, most segmentation models remain opaque, where they lack the granularity required for component-level analysis. As a result, when segmentation models fail, it is difficult to identify which internal representations are responsible, limiting developers’ ability to diagnose errors, improve robustness, or establish trust in clinical settings. Existing …

A Fishy Situation: Hand Infection Due To Mycobacterium Marinum Mistaken For Giant Cell Tumor, Alynna Knaub, Dylan Baker, Jennifer Hanrahan

Department of Medicine Faculty Publications

Mycobacterium marinum is an acid-fast bacterium (AFB) associated with exposure to water and aquatic species. When inoculated, infection can result in nodular cutaneous lesions. In the absence of detailed history or culture data, these nodular skin lesions can be mistaken for noninfectious orthopedic conditions. We present a case of M. marinum mistaken for a giant cell tumor. This case illustrates the overlap in these conditions, as well as the utility of QuantiFERON Gold testing to provide supportive evidence for the diagnosis of Mycobacterium marinum.

[Introduction]

Case description

A 25-year-old woman with a history of ulcerative colitis treated with multiple abdominal surgeries complicated by peristomal pyoderma gangrenosum (PPG) presented with severe peristomal pain and ulceration. Treatment course was complicated; disease control was achieved via combination infliximab 10 mg/kg every 4 weeks, corticosteroids (topical triamcinolone 0.1% ointment, intralesional 10 mg/ml injections, and oral prednisone 30 mg daily with a gradual taper), and cyclosporine 125 mg tapering by 25 mg every 3 weeks, ultimately tapered to infliximab monotherapy.

Background: Acute valve syndrome (AVS) represents a high-risk phenotype of advanced valvular disease with largely uncharacterized risk heterogeneity. We aimed to validate an expanded AVS definition and develop a physiology-dependent risk stratification tool using available clinical markers.

Methods: This retrospective study analyzed 2380 patients undergoing aortic valve replacement for severe aortic stenosis and classified them as AVS (n = 1556) or progressive valvular disease (n = 824). The primary outcome was 1-year all-cause mortality. An L2-regularized logistic regression model was developed to predict 1-year mortality using admission laboratory markers and comorbidity burden. Model performance was assessed using nested cross-validation with …

[Introduction] Crohn disease is a chronic inflammatory bowel disease that affects the gastrointestinal tract from the mouth to the anus. Extra-intestinal manifestations of Crohn disease are common, with the skin being the most commonly involved site.¹ Cutaneous manifestations of Crohn include lesions that directly extend from the bowel to the skin, whereas extraintestinal Crohn disease involves sites that do not directly extend from the bowel.¹ Extraintestinal Crohn disease is often resistant to treatments and often does not parallel the activity of the bowel disease.¹ There have only been 3 documented cases of extraintestinal Crohn disease responding to upadacitinib.²,³ We describe …
