Prediction of coronary artery disease based on facial temperature information captured by non-contact infrared thermography.

Background: Current approaches for initial coronary artery disease (CAD) assessment rely on pretest probability (PTP) based on risk factors and presentations, with limited performance. Infrared thermography (IRT), a non-contact technology that detects surface temperature, has shown potential in assessing atherosclerosis-related conditions, particularly when measured from body regions such as faces. We aim to assess the feasibility of using facial IRT temperature information with machine learning for the prediction of CAD.

In our study, we explored the Abhydrolase Domain Containing 5 (ABHD5) mechanism in ACM about histone deacetylase 4 (HDAC4) and CaM-CaMKII/MEF2 signaling pathway. Rat models of ACM were established in Wistar rats, and in vitro cell models were constructed in rat cardiomyocytes H9C2 utilizing 12-h of treatment of Alcohol (200 mM) to study the regulatory role of ABHD5 in ACM with the involvement of HDAC4 and CaM-CaMKII/MEF2 signaling pathway, as evidenced by determination of cardiac function, myocardial fibrosis, apoptosis of cardiomyocytes and oxidative stress condition.

Effect of NaNO, NHCl and urea on the fate and transformation of various typical microplastics in porous media.

Understanding the transport behaviors of microplastics (MPs) in porous media is crucial in controlling MPs pollution. Given nitrogen is one of the most important nutrients in soil and groundwater systems, unclearness of the transport behaviors of microplastics (MPs) under various nitrogen conditions may inhibit the acknowledgment of MPs fate. For this reason, this study innovatively investigates the transport characteristics of four kinds of typical MPs (PVC MPs, PMMA MPs, PET MPs, and PP MPs) under various NaNO, NHCl and urea conditions via column experiments numerical models.

We aimed to assess the prognostic value of NT-proBNP beyond clinical risk prediction tools, and its relevance to follow-up events and interactions with different treatment selections. The study included 11,987 patients who underwent CABG who underwent surgery between 2014 and 2018.

Comparative analysis of machine learning vs. traditional modeling approaches for predicting in-hospital mortality after cardiac surgery: temporal and spatial external validation based on a nationwide cardiac surgery registry.

Aims: Preoperative risk assessment is crucial for cardiac surgery. Although previous studies suggested machine learning (ML) may improve in-hospital mortality predictions after cardiac surgery compared to traditional modeling approaches, the validity is doubted due to lacking external validation, limited sample sizes, and inadequate modeling considerations. We aimed to assess predictive performance between ML and traditional modelling approaches, while addressing these major limitations.
