Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset [PDF]

open access: yesarXiv, 2023
Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this challenge, we propose a post-processing approach that leverages a data-driven method to repair the ...

Bruton tyrosine kinase inhibitors in the management of Waldenström macroglobulinemia

open access: yesAmerican Journal of Hematology, Volume 98, Issue 2, Page 338-347, February 2023., 2023
Abstract Bruton tyrosine kinase (BTK) inhibitors have taken a central role in the management of patients with Waldenström macroglobulinemia and are the only agents approved by the Food and Drug Administration (FDA) to treat these patients. Although associated with high rates of durable responses, unmet needs with BTK inhibitor therapy include ...

Flow characteristics of the proximal pulmonary arteries and vena cava in patients with chronic thromboembolic pulmonary hypertension: correlation between 3.0 T phase-contrast MRI and right heart catheterization

open access: yesDiagnostic and Interventional Radiology, 2014
PURPOSEWe aimed to determine the correlation between flow characteristics of the proximal pulmonary arteries and vena cava obtained by 3.0 T phase-contrast magnetic resonance imaging (MRI) and hemodynamic characteristics by right heart catheterization in

PHT-bot: Deep-Learning based system for automatic risk stratification of COPD patients based upon signs of Pulmonary Hypertension [PDF]

open access: yesProc. SPIE 10950, Medical Imaging 2019: Computer-Aided Diagnosis, 109500O, 2019
Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality worldwide. Identifying those at highest risk of deterioration would allow more effective distribution of preventative and surveillance resources. Secondary pulmonary hypertension is a manifestation of advanced COPD, which can be reliably diagnosed by the main ...

Pulmonary Artery Denervation Reduces Pulmonary Artery Pressure and Induces Histological Changes in an Acute Porcine Model of Pulmonary Hypertension

open access: yesCirculation. Cardiovascular Interventions, 2015
Background—Pulmonary arterial hypertension is a devastating disease with high morbidity and mortality and limited treatment options. Recent studies have shown that pulmonary artery denervation improves pulmonary hemodynamics in an experimental model and ...

Successful depiction of systemic collateral supply to pulmonary artery in CTEPH using time-resolved 4D CT angiography: a case report

open access: yesPulmonary Circulation, 2020
A 49-year-old man with CTEPH (pre-procedural mean pulmonary artery pressure: 36 mmHg) underwent balloon pulmonary angioplasty. Chronic total occlusion of the left inferior pulmonary artery trunk was observed.

Anatomical characterization of pulmonary artery and implications to pulmonary artery pressure monitor implantation

open access: yesScientific Reports, 2023
In patients with heart failure, guideline directed medical therapy improves outcomes and requires close patient monitoring. Pulmonary artery pressure monitors permit remote assessment of cardiopulmonary haemodynamics and facilitate early intervention ...

Noninvasive Estimation of Mean Pulmonary Artery Pressure Using MRI, Computer Models, and Machine Learning [PDF]

open access: yesarXiv, 2023
Pulmonary Hypertension (PH) is a severe disease characterized by an elevated pulmonary artery pressure. The gold standard for PH diagnosis is measurement of mean Pulmonary Artery Pressure (mPAP) during an invasive Right Heart Catheterization. In this paper, we investigate noninvasive approach to PH detection utilizing Magnetic Resonance Imaging ...

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study

open access: yesAmerican Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023
Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...

SGLT inhibitors attenuate NO-dependent vascular relaxation in the pulmonary artery but not in the coronary artery.

open access: yesAmerican Journal of Physiology - Lung cellular and Molecular Physiology, 2015
Inhibitors of sodium-glucose cotransporter (SGLT)2 are a new class of oral drugs for type 2 diabetic patients that reduce plasma glucose levels by inhibiting renal glucose reabsorption.
