INTRODUCTION: Oral cavity squamous cell carcinoma (OSCC) occurs most frequently in patients >60 years old with a history of tobacco and alcohol use. Epidemiological studies describe increased incidence of OSCC in younger adults (years). Despite its poor prognosis, knowledge of OSCC tumor microenvironment (TME) characteristics in younger adults is scarce and could help inform possible resistance to emerging treatment options.
METHODS: Patients with OSCC were evaluated using TCGA-HNSC (n=121) and a stage and subsite-matched institutional cohort (n=8) to identify differential gene expression focusing on the extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) processes in younger (≤45 years) vs. older adults …
Amiodarone-Induced Lung Toxicity: An Underrecognized And Fatal Presentation, 2024 Rochester General Hospital
Amiodarone-Induced Lung Toxicity: An Underrecognized And Fatal Presentation, Andrew Takla, Fahad Eid, Hina Ukrani, Moghniuddin Mohamed, Elizabeth Lee
Advances in Clinical Medical Research and Healthcare Delivery
Amiodarone, a widely utilized antiarrhythmic drug, poses a significant risk of amiodarone-induced lung toxicity (ALT) in up to 10% of patients and can be fatal. This report presents the diagnostic challenges associated with ALT, given its non-specific clinical and radiological presentation. Clinicians should maintain a high index of suspicion for potential ALT, especially in patients with progressive respiratory failure despite optimization of other potential causes such as CHF. The mainstay of treatment is discontinuing amiodarone and initiating steroids. However, outcomes can remain unpredictable, emphasizing the need for heightened awareness and regular monitoring of patients on amiodarone therapy.

Department of Neurosurgery Faculty Papers
Background and purpose: While mechanical thrombectomy (MT) achieves restoration of cerebral blood flow to the area at risk in patients with acute ischemic stroke (AIS), the influx of blood flow may exacerbate the blood-brain barrier (BBB) disruption and extravasation across the BBB, and it therefore remains unclear how reperfusion impacts the blood-brain barrier integrity. In this study, we use diffusion-prepared pseudocontinuous ASL (DP-pCASL) and Neurite Orientation Dispersion and Density Imaging (NODDI) sequence to measure the water exchange rate (kw) in patients who underwent either MT or medical management and determine its impact on the brain tissue microstructure in …

Department of Medicine Faculty Papers
BACKGROUND: The use of anesthetics may result in depression of the hypoxic ventilatory response. Since there are no receptor-specific antagonists for most anesthetics, there is the need for agnostic respiratory stimulants that increase respiratory drive irrespective of its cause. The authors tested whether ENA-001, an agnostic respiratory stimulant that blocks carotid body BK-channels, could restore the hypoxic ventilatory response during propofol infusion. They hypothesize that ENA-001 is able to fully restore the hypoxic ventilatory response.
METHODS: In this randomized, double-blind crossover trial, 14 male and female healthy volunteers were randomized to receive placebo and low- and high-dose ENA-001 on three …

Dissertations, Theses, and Capstone Projects
The last half century has played witness to the onset of molecular imaging for the clinical assessment of physiological targets. While several medical imaging modalities allow for the visualization of the functional and anatomical properties of humans and living systems, few offer accurate quantitation and the ability to detect biochemical processes with low-administered drug mass doses. This limits how physicians and scientists may diagnose and treat medical issues, such as cancer, disease, and foreign agents.
A promising alternative to extant invasive procedures and suboptimal imaging modalities to assess the nature of a biological environment is the use of positron emission …
