This study aimed to develop a lipidomic-enhanced risk score (LRS), specifically targeting risk prediction and reclassification within the intermediate group, benchmarked against the FRS.

Methods

The LRS was developed via a machine learning workflow using ridge regression on the Australian Diabetes, Obesity, and Lifestyle Study (AusDiab; n = 10,339). It was externally validated with the Busselton Health Study (n = 4,492), and …

Computer Simulation Of Catheter Cryoablation For Pulmonary Vein Isolation, Solange I. Rivera, Clara P. Bernal, Rafael Martínez-Peláez, Rogelio Robledo-Nolasco, Gerardo De León-Larios, Vanessa G. Félix, Rodolfo Ostos, Gladys Maestre, Jesus Melgarejo, Luis J. Mena

School of Medicine Publications

Cryoablation is a well-established medical procedure for surgically treating atrial fibrillation. Cryothermal catheter therapy induces cellular necrosis by freezing the insides of pulmonary veins, with the goal of disrupting abnormal electrical heart signals. Nevertheless, tissue damage induced by cold temperatures may also lead to other complications after cardiac surgery. In this sense, the simulation of catheter ablation can provide safer environments for training and the performance of cryotherapy interventions. Therefore, in this paper, we propose a novel approach to help better understand how temperature rates can affect this procedure by using computer tools to develop a simulation framework to predict …

Using the Subtype and Stage Inference (SuStaIn) algorithm, we identify two distinct neurostructural subgroups by mapping the spatial and temporal ‘trajectory’ of gray matter change in schizophrenia. Subgroup 1 was characterized by an early cortical-predominant loss with enlarged striatum, whereas subgroup 2 displayed an early subcortical-predominant loss in the hippocampus, striatum and other …

Potential Association Between Arsenic And Vitamin D, Mythri Chittilla, Chantal Uzoma, Desiree Brewer, Mohammed S. Razzaque

School of Medicine Publications

Vitamin D is a pleiotropic hormone that regulates calcium and phosphate homeostasis. The roles of vitamin D can be divided into skeletal and nonskeletal. Its skeletal roles include promoting calcium absorption in the intestines, maintaining adequate levels of calcium and phosphate in the bloodstream, and supporting bone mineralization, thus preventing conditions such as rickets and osteoporosis. Nonskeletal roles encompass a range of functions, including immune system modulation, cardiovascular health, and cell growth regulation. Sufficient concentrations of vitamin D in the bloodstream are 20–100 ng/ml in men, women, and children, but individuals with more pigmented skin, live in environments with less …

Resting State Electroencephalographic Brain Activity In Neonates Can Predict Age And Is Indicative Of Neurodevelopmental Outcome, Amir Ansari, Kirubin Pillay, Emad Arasteh, Anneleen Dereymaeker, Gabriela Schmidt Mellado, Katrien Jansen, Anderson M. Winkler, Gunnar Naulaers, Aomesh Bhatt, Sabine Van Huffel

School of Medicine Publications

Objective: Electroencephalography (EEG) can be used to estimate neonates' biological brain age. Discrepancies between postmenstrual age and brain age, termed the brain age gap, can potentially quantify maturational deviation. Existing brain age EEG models are not well suited to clinical cot-side use for estimating neonates' brain age gap due to their dependency on relatively large data and pre-processing requirements.

Methods: We trained a deep learning model on resting state EEG data from preterm neonates with normal neurodevelopmental Bayley Scale of Infant and Toddler Development (BSID) outcomes, using substantially reduced data requirements. We subsequently tested this model in two independent datasets …

School of Medicine Publications

In the study of coronary artery disease (CAD), the mechanism of plaque formation and development is still an important subject for investigation. A limitation of current coronary angiography (CAG) is that it can only show static images of the narrowing of arterial channels without identifying the mechanism of the disease or predicting its progression or regression. To address this limitation, the CAG technique has been modified. The new approach emphasizes identifying and analyzing blood flow patterns, employing methodologies akin to those used by hydraulic engineers for fluid or gas movement through domestic or industrial pipes and pumps. With the new …
