A Computer Vision Pipeline for Automated Determination of Cardiac Structure and Function and Detection of Disease by Two-Dimensional Echocardiography [PDF]

open access: yesarXiv, 2017
Automated cardiac image interpretation has the potential to transform clinical practice in multiple ways including enabling low-cost serial assessment of cardiac function in the primary care and rural setting. We hypothesized that advances in computer vision could enable building a fully automated, scalable analysis pipeline for echocardiogram (echo ...

Proportional pulse pressure relates to cardiac index in stabilized acute heart failure patients

open access: yesClinical and Experimental Hypertension, 2018
Aims: In chronic heart failure, proportional pulse pressure (PPP) is suggested as an estimate of cardiac index (CI). The association between CI and PPP in acute heart failure (AHF) has not been described.

Surface dose analysis and dosimetric comparison of Halcyon versus Truebeam in breast cancer radiotherapy: An OSL dosimetry study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Breast cancer is a neoplastic disease with high prevalence among women. Radiotherapy is one of the principal treatment modalities for this disease, but it poses significant challenges. This study aimed to compare and evaluate the technical and dosimetric performance of conventional C‐arm linac systems and a new design, Halcyon, in the ...

Log file‐based quality assurance method for respiratory gating system

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

A Multi-Trait Approach Identified Genetic Variants Including a Rare Mutation in RGS3 with Impact on Abnormalities of Cardiac Structure/Function [PDF]

open access: yesarXiv, 2018
Heart failure is a major cause for premature death. Given heterogeneity of the heart failure syndrome, identifying genetic determinants of cardiac function and structure may provide greater insights into heart failure. Despite progress in understanding the genetic basis of heart failure through genome wide association studies, heritability of heart ...

Pulse pressure variation and systolic pressure variation in mechanically ventilated children

open access: yesPaediatrica Indonesiana, 2011
Background In mechanically ventilated patients, changes in breathing patterns may affect the preload, causing stroke volume fluctuation. Pulse pressure variation (PPV) and systolic pressure variation (SPV) are dynamic means of the hemodynamic monitoring ...

Music Interventions in Hyperacute and Acute Stroke Patients: A Randomized Controlled Pilot Feasibility Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute

Development of a Disease Model for Predicting Postoperative Delirium Using Combined Blood Biomarkers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Postoperative delirium, a common neurocognitive complication after surgery and anesthesia, requires early detection for potential intervention. Herein, we constructed a multidimensional postoperative delirium risk‐prediction model incorporating multiple demographic parameters and blood biomarkers to enhance prediction accuracy ...

Clinical Phenotyping of Long COVID Patients Evaluated in a Specialized Neuro‐COVID Clinic

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To report Long COVID characteristics and longitudinal courses of patients evaluated between 4/14/21–4/14/22 at the University of Pennsylvania Neurological COVID Clinic (PNCC), including clinical symptoms, neurological examination findings, and neurocognitive screening tests from a standardized PNCC neurological evaluation approach ...

Stenting of the artery of Dr A.N. Kazantsev in the acute period of ischemic stroke

open access: yesRadiology Case Reports, 2022
The A.N. Kazantsev artery is a vessel starting from the common carotid artery with subsequent bifurcation into 2 vessels of equal size—the internal carotid artery (ICA) and the persistent embryonic hypoglossal artery (PEHA).
