Longitudinal quantile regression in presence of informative drop-out through longitudinal-survival joint modeling [PDF]

open access: yesarXiv, 2014
We propose a joint model for a time-to-event outcome and a quantile of a continuous response repeatedly measured over time. The quantile and survival processes are associated via shared latent and manifest variables. Our joint model provides a flexible approach to handle informative drop-out in quantile regression.

Dilations of Linear Maps on Vector Spaces [PDF]

open access: yesarXiv, 2021
We continue the study dilation of linear maps on vector spaces introduced by Bhat, De, and Rakshit. This notion is a variant of vector space dilation introduced by Han, Larson, Liu, and Liu. We derive vector space versions of Wold decomposition, Halmos dilation, N-dilation, inter-twining lifting theorem and a variant of Ando dilation.

Echocardiographic profile of patients with cardiomyopathy

open access: yesJournal of Lumbini Medical College, 2018
Introduction: Cardiomyopathies represent a heterogeneous group of diseases that often lead to progressive heart failure with significant morbidity and mortality. Exact epidemiological data on cardiomyopathy in Nepal are lacking.

Automatic Segmentation and Disease Classification Using Cardiac Cine MR Images [PDF]

open access: yesarXiv, 2017
Segmentation of the heart in cardiac cine MR is clinically used to quantify cardiac function. We propose a fully automatic method for segmentation and disease classification using cardiac cine MR images. A convolutional neural network (CNN) was designed to simultaneously segment the left ventricle (LV), right ventricle (RV) and myocardium in end ...

Molecular studies in familial dilated cardiomyopathy – A pilot study

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2022
Aim: To study genetic variants in patients of familial dilated cardiomyopathy. Methodology: Patients with reduced ejection fraction of less than 45% and dilated left ventricle are considered to have dilated cardiomyopathy.

Taurine deficiency and dilated cardiomyopathy in golden retrievers fed commercial diets

open access: yesPLoS ONE, 2018
Introduction Golden retrievers are over-represented in cases of taurine-deficient dilated cardiomyopathy and recently a surge in cases has prompted further investigation.

Deep learning approach to left ventricular non-compaction measurement [PDF]

open access: yesarXiv, 2020
Left ventricular non-compaction (LVNC) is a rare cardiomyopathy characterized by abnormal trabeculations in the left ventricle cavity. Although traditional computer vision approaches exist for LVNC diagnosis, deep learning-based tools could not be found in the literature.

Nicotinamide Riboside Preserves Cardiac Function in a Mouse Model of Dilated Cardiomyopathy

open access: yesCirculation, 2017
Background: Myocardial metabolic impairment is a major feature in chronic heart failure. As the major coenzyme in fuel oxidation and oxidative phosphorylation and a substrate for enzymes signaling energy stress and oxidative stress response, nicotinamide

Feature Tracking Cardiac Magnetic Resonance via Deep Learning and Spline Optimization [PDF]

open access: yesarXiv, 2017
Feature tracking Cardiac Magnetic Resonance (CMR) has recently emerged as an area of interest for quantification of regional cardiac function from balanced, steady state free precession (SSFP) cine sequences. However, currently available techniques lack full automation, limiting reproducibility.

Dilated cardiomyopathy due to hypocalcaemia: a case report

open access: yesJournal of Medical Case Reports
Background Hypocalcaemia is a rare, but reversible, cause of dilated cardiomyopathy causing heart failure. Several case reports have been reported on reversible cardiomyopathy secondary to hypocalcaemia.
