Automatic Pulmonary Artery-Vein Separation in CT Images using Twin-Pipe Network and Topology Reconstruction [PDF]

arXiv, 2021
With the development of medical computer-aided diagnostic systems, pulmonary artery-vein(A/V) separation plays a crucial role in assisting doctors in preoperative planning for lung cancer surgery. However, distinguishing arterial from venous irrigation in chest CT images remains a challenge due to the similarity and complex structure of the arteries ...

A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

Advanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

Adherence with cardiovascular medications and the outcomes in patients with coronary arterial disease: “Real‐world” evidence

Clinical Cardiology, Volume 45, Issue 12, Page 1220-1228, December 2022., 2022
Abstract Background Cardiovascular medications are vital for the secondary prevention of coronary arterial disease (CAD). However, the effect of cardiovascular medication may depend on the optimal adherence of the patients. This meta‐analysis aims to determine the magnitude of adherence to vascular medications that influences the absolute and relative ...

CCDC80 Protects against Aortic Dissection and Rupture by Maintaining the Contractile Smooth Muscle Cell Phenotype

Advanced Science, EarlyView.
Aortic dissection (AD) is accompanied by a decrease in CCDC80 in vascular smooth muscle cells (VSMCs). CCDC80 can interact with JAK2, and VSMC‐specific CCDC80 deficiency accelerates the progression of AD by activating the JAK2/STAT3 pathway involved in regulating the phenotype switching and function of VSMCs.

Long‐term outcome prediction for chronic thromboembolic pulmonary hypertension after pulmonary endarterectomy

Clinical Cardiology, Volume 45, Issue 12, Page 1255-1263, December 2022., 2022
Abstract Background The definitive treatment for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA), which has good long‐term outcomes. However, after surgery, a quarter of the patients still have residual pulmonary hypertension (RPH). In pulmonary hemodynamics, there are no unified criteria for RPH, even though the

Influence of image segmentation on one-dimensional fluid dynamics predictions in the mouse pulmonary arteries [PDF]

, 2019
Computational fluid dynamics (CFD) models are emerging as tools for assisting in diagnostic assessment of cardiovascular disease. Recent advances in image segmentation has made subject-specific modelling of the cardiovascular system a feasible task, which is particularly important in the case of pulmonary hypertension (PH), which requires a combination

A Touch Enabled Hemodynamic and Metabolic Monitor

Advanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Multimorbidity, functional impairment, and mortality in older patients stable after prior acute myocardial infarction: Insights from the TIGRIS registry

Clinical Cardiology, Volume 45, Issue 12, Page 1277-1286, December 2022., 2022
Abstract Background Data on the association of multimorbidity and functional impairment with cardiovascular (CV) and non‐CV outcomes among older myocardial infarction (MI) patients are limited. Hypothesis Multimorbidity and functional impairment among older MI patients are associated with CV and non‐CV mortality.
