Objective: Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large-scale comparison of US-based assessment with histologic markers of skin fibrosis has not been reported. We evaluated US-based skin assessments for their face validity (differentiation between involved SSc and healthy control [HC] skin), construct validity (comparison to modified Rodnan skin score [mRSS]), and criterion validity (comparison to histologic and gene expression fibrosis markers).
Methods: Twenty HCs and 52 patients with SSc underwent clinical and US assessment followed by a forearm skin biopsy. Predefined areas were assessed on the finger, hand, …

Transvascular Endobronchial Ultrasound-Guided Transbronchial Needle Aspirations (Ebus-Tbna) To Confirm Urothelial Carcinoma Metastasis To The Pulmonary Artery, Kyle Admire, Stephen Gegick
Department of Medicine Faculty Publications
Tumours within the pulmonary arteries provide a diagnostic challenge due to their similar appearance to pulmonary emboli. Often, the decision to sample is multidisciplinary and the best approach to take is often unknown. Here we describe a case of urothelial carcinoma which metastasised to the mediastinum with evidence of tumour burden within the pulmonary artery. Sampling of this by endovascular and thoracoscopic means was unsuccessful; however, we were able to provide a diagnosis using direct visualization with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). This report is the first of a central pulmonary artery tumour caused by urothelial carcinoma biopsied by …

Persistent Hypoxemia On Home Sleep Apnea Testing Prompting Further Evaluation For Pulmonary Embolism: A Case Report, Kyle Admire, Andrew Githaiga
Department of Medicine Faculty Publications
Obstructive sleep apnea is a condition characterized by recurrent upper airway collapse during sleep, which may be associated with sleep disruption and repetitive oxygen desaturations. It is diagnosed by nocturnal in-lab polysomnography or home sleep apnea testing. We present a case of an otherwise healthy individual who had home sleep apnea testing that revealed persistent, unexplained hypoxemia which, on further investigation, was found to be due to a saddle pulmonary embolism.

[Case presentation] A man in his 60's with a history of hypertension, hyperlipidemia, and resected colon cancer in remission presented with a 4-month history of an enlarging nodule on the right fourth fingertip. The patient recalled having a splinter removed from the same site a few weeks prior to the development of the lesion. The lesion was initially diagnosed by an orthopaedist as a pyogenic granuloma (Figure 1a), and the patient was advised to apply table salt to the area several times daily. However, the lesion continued to enlarge over 3 months with occasional bleeding and mild tenderness. Physical examination …
All-Inside Arthroscopic Technique For Repairing Radial Meniscus Tears At The Anterior Horn-Body Junction, Brandon Omari Boyd, Robert M. Walker, Harrison A. Volaski, Ferdinand J. Chan
All-Inside Arthroscopic Technique For Repairing Radial Meniscus Tears At The Anterior Horn-Body Junction, Brandon Omari Boyd, Robert M. Walker, Harrison A. Volaski, Ferdinand J. Chan
Department of Medicine Faculty Publications
Radial meniscus tears are a common tear pattern that, if left untreated, can ultimately lead to accelerated degenerative changes and disability. There is well-established evidence that supports meniscal preservation in patients with radial meniscus tears. Various surgical techniques are used to repair radial tears, including inside-out, outside-in, and all-inside methods. Self-retrieving all-inside devices are a safe option when repairing radial tears. However, radial tears at the junction of the anterior horn and body present a unique surgical challenge, as surgeons may have difficulty maneuvering the jaws of the self-retrieving suture device around the anterior limb of the meniscal tear. We …

Despite sustained public health efforts, hypertension remains highly prevalent in the United States, with persistent disparities across demographic and socioeconomic groups. We examined 25-year trends in hypertension prevalence, undiagnosed hypertension, and on-treatment uncontrolled hypertension in the United States using nationally representative National Health and Nutrition Examination Survey (NHANES) data from adults aged ≥18 years. Hypertension was defined as systolic BP ≥130 mmHg, diastolic BP ≥80 mmHg, or current antihypertensive use. Undiagnosed hypertension was defined as elevated BP without prior diagnosis or treatment, while on-treatment uncontrolled hypertension was defined as diagnosed hypertension with BP ≥130/80 mmHg despite treatment. Survey-weighted generalized linear …

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.

Percutaneous Closure Of Ventricular Septal Rupture After Myocardial Infarction:, Thomas A. Cook, Simone K. Schumaecker, Anjani Patibandla, Nicholas J. Valle, Matthew R. Summers
Department of Medicine Faculty Publications
BACKGROUND: Ventricular septal rupture (VSR) following acute myocardial infarction is a rare but deadly complication with mortality rates exceeding 90% when left untreated. Coronary ischaemia leads to myocardial necrosis and friability resulting in septal rupture, most commonly 3-5 days post-infarction. The sudden development of a left-to-right shunt causes volume overload in the right ventricle, pulmonary vasculature, and left atrium, precipitating biventricular failure, and cardiogenic shock. Management requires careful consideration of timing and modality of closure along with stabilization with mechanical circulatory support in severe cases.
CASE SUMMARY: A 65-year-old female presented with anterior ST-segment elevation myocardial infarction complicated by VSR …

Baseline Lymphopenia Predicts Survival In Ici-Naïve Solid Tumor Patients Receiving Immune Checkpoint Inhibitors: A Propensity-Matched Real-World Pan-Cancer Analysis, Ahmed Ismail, Nina Balanchivadze, George R. Simon, Yanis Boumber
Department of Medicine Faculty Publications
Background: Baseline lymphopenia is common among advanced solid tumors and may influence the efficacy/safety of immune checkpoint inhibitors (ICIs), but large real-world evidence is limited. We evaluated the association between baseline absolute lymphocyte count (ALC) and clinical outcomes in adults with solid tumors treated with ICIs in routine practice. Methods: We performed a retrospective cohort study using TriNetX. Adults with solid tumors who received pembrolizumab, nivolumab, or atezolizumab (ICI-Naïve) between January 2015 and June 2026 were included. Baseline ALC was measured within 30 days before first treatment and was classified as lymphopenic (ALC < 1.5 × 10⁹/L) or non-lymphopenic (ALC ≥ 1.5 × 10⁹/L). Propensity score matching (1:1) yielded 5249 patients per group. The index date was the first immunotherapy date, and outcomes were assessed at 6, 12, 24, 36 months, and 5 years. The primary outcome was 24-month overall survival (OS); secondary outcomes were OS at 6 and 12 months and 6-month risks of healthcare utilization, immune-related adverse events (irAEs), and serious infections; and exploratory outcomes included OS at 36 months and 5 years. All outcomes were analyzed using Kaplan–Meier analysis, Cox proportional hazards models, and risk ratios. Subgroup analysis included OS stratified by solid tumor subtypes and prior lines of therapy. Results: After matching, patients with baseline lymphopenia …

Department of Medicine Faculty Publications
Background and AIMS
Fully covered self-expandable metal stents (FcSEMSs) have become the mainstay of treatment for a variety of biliary pathologies. However, FcSEMSs have been associated with a greater rate of stent migration than other types of stents. A technique of anchoring double-pigtail plastic stents (DPPSs) has been proposed to minimize migration of biliary FcSEMSs. Herein, we evaluated the efficacy of anchoring DPPSs among patients treated with biliary FcSEMSs.
Methods
We performed a systematic review using PubMed, EMBASE, and Web of Science from database inception through August 2023. Full-text articles comparing FcSEMSs with or without anchoring DPPSs were included. We …

Computed tomography (CT) and computational modeling (DASI) in redo transcatheter aortic valve replacement (TAVR) planning.
Case Summary
A 77-year-old woman presented with severe symptomatic aortic stenosis due to degeneration of a prior transcatheter valve. CT demonstrated leaflet calcification with borderline left-sided valve-to-coronary distance (3.27 mm). Geometric assessment suggested low right coronary obstruction risk, but higher left main risk. Computational modeling demonstrated adequate leaflet-coronary clearance (distance from displaced leaflet cusp to coronary ostium normalized to coronary diameter >0.7). Redo TAVR with a 26-mm Evolut FX was performed without leaflet modification and no coronary obstruction.

Micro- and nanoplastics (MNPs) are plastic particles smaller than 5 mm and 1 μm, respectively, and are emerging environmental pollutants with growing implications for human health. These particles stem from either 'primary sources', such as intentionally manufactured microbeads and industrial abrasives, or 'secondary sources', where larger plastic items break down into smaller fragments over time. Human exposure primarily occurs through ingestion and inhalation, with contaminated seafood and plastic-laden food packaging representing key routes of entry. Once ingested, MNPs can cross the intestinal barrier, accumulate in gastrointestinal (GI) tissues, and trigger biological responses. Mechanistic studies reveal that MNPs induce oxidative stress, …

Recent advances in the pharmacological therapy of heart failure with reduced ejection fraction (HFrEF) have significantly impacted the overall survival, heart failure hospitalisations and rates of sudden cardiac death (SCD). In this context, the relevant timing of placing ICDs as primary prevention is a matter of on-going debate. This manuscript provides evidence for an updated view regarding the timing of implanting ICD in eligible patients with HFrEF receiving optimal guideline-directed medical therapy, accounting for the timing to reverse cardiac remodelling (RCR) occurrence and residual SCD risks over time. Clinically significant RCR occurs beyond 3 months of optimal guideline-directed medical therapy, …
