Safety And Feasibility Of Same-Admission Transcarotid Arterial Revascularization Prior To Heart Surgery For Patients Presenting With Concurrent, Severe Carotid Artery Stenosis, And Surgical Cardiac Disease, Brittany Landavazo, Matthew D. Kenny, Chandler Vernon, Nicolas Zea, David Nation, Bradley Boone, Jeff Apple, Kofi Quaye, Shir Yelovitch, Ryan S. Turley

HCA Healthcare Journal of Medicine

Introduction

Carotid artery stenosis and coronary artery disease are often co-morbid, with a prevalence of concurrent carotid and coronary artery stenosis approaching 50%. The optimal treatment for these patients has long been debated, with open carotid revascularization generally reserved for those with severe symptomatic carotid disease that precludes cardiac surgery. In this scenario, the role of less-invasive carotid artery stenting, particularly transcarotid arterial revascularization (TCAR), remains controversial and is not yet well studied. This study aims to present our outcomes and methodology for treating severe carotid stenosis with TCAR prior to cardiac surgery.

The Efficacy Of The Fitzpatrick Scale In Clinical Practice, Dana Olsen, Cecilia Nguyen, Marshall Hall, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Many skin diseases can manifest differently depending on the pigment of one’s skin. The Fitzpatrick scale is a classification of phototypes (I-VI) that categorizes patients' skin based on its ability to tan and burn. Even though it is a simple questionnaire, the Fitzpatrick scale has numerous criticisms due to its dependence on patients’ self-perception, variability in how questions are asked, limited range, and the underestimation of the risk of skin cancers. Alternatives to the Fitzpatrick scale include the melanin index, pigment protection factor, a visual color scale, and using artificial intelligence along with existing or new scales. Having a more …

Evaluating Regularized Logistic Regression And K-Nn On Mnist Under Increasing Random Missingness, Daniel Markwei Feb 2026

Evaluating Regularized Logistic Regression And K-Nn On Mnist Under Increasing Random Missingness, Daniel Markwei

Data Science and Data Mining

This paper investigates the effect of random missingness on the performance of regularized multinomial logistic regression and the k-nearest neighbors (k-NN) classifier for handwritten digit recognition on the MNIST dataset. In particular, we study L1-regularized (LASSO) logistic regression and L2-regularized (Ridge) logistic regression alongside k-NN. Varying percentages of random missingness were introduced into the original dataset, and each model was evaluated in terms of its classification performance. The results show that random missingness degrades the performance of all three classifiers. Overall, k-NN consistently achieves higher accuracy than both L1- and L2-regularized logistic regression across all missingness levels; however, its performance …
