Early outcomes of robotic versus video-thoracoscopic anatomical segmentectomy: a propensity score-matched real-world study.

Objectives: Minimally invasive anatomic segmentectomy for the resection of pulmonary nodules has significantly increased in the last few years. Nevertheless, there is limited evidence on the safety and feasibility of robotic segmentectomy compared to video-assisted thoracic surgery. This study aimed to compare the real-world early outcomes of robotic and video-thoracoscopic surgery in anatomic segmentectomy.

An intelligent aortic valve model for complete cardiac cycle.

The aortic valve (AV) is crucial for cardiovascular (CV) hemodynamic, impacting cardiac output (CO) and left ventricular volumetric flow rate (LVQ). Its nonlinear behavior challenges standard LVQ prediction methods as well as CO one. This study presents a novel approach for modeling the AV in the CV system, offering an improved method for estimating crucial parameters like LVQ across various AV conditions, including aortic stenosis (AS).

A New Cardiovascular Mock Loop Driven by Novel Active Capacitance in Normal and Abnormal Conditions.

The hybrid mock circulatory loop (hMCL) serves as a crucial hemodynamic simulation tool, offering exceptional flexibility, controllability, and reproducibility for investigating the mechanisms underlying cardiovascular diseases (CVD) in a controlled environment, circumventing the limitations of live organism studies. This paper introduces a novel design and control strategy for hMCL, introducing a novel left ventricle volume-elastance (LVVE) equation that unifies the autoregulation of the Frank-Starling mechanism (FSM) with left ventricle contractility (LVC). LVVE establishes a dynamic link between left ventricular volume (LVV) and LVC, inherently satisfying the regulatory relationship between left ventricular pressure (LVP) and LVV through a mathematical equation.

Contralateral hemopneumothorax after penetrating thoracic trauma: A case report.

Background: Trauma is the leading cause of death in young adults up to the age of 45 years. Hemothorax is a frequent consequence of penetrating thoracic trauma, and is usually associated with pneumothorax and pneumoderma. Intercostal arterial bleeding or intrathoracic hemorrhage occurs after penetrating thoracic trauma, and uncontrolled bleeding is the main cause of death.
