Robot-Assisted CT-guided Biopsy with an Artificial Intelligence-Based Needle-Path Generator: An Experimental Evaluation Using a Phantom Model.

Purpose: To investigate the feasibility of a robotic system with artificial intelligence-based lesion detection and path planning for CT-guided biopsy, compared to the conventional freehand technique.

Materials And Methods: Eight nodules within an abdominal phantom, incorporating the simulated vertebrae and ribs, were designated as targets. A robotic system was used for lesion detection, trajectory generation, and needle-holder positioning.

Wristwatch pulse wave monitoring: assessing daily activity post-catheter ablation for atrial fibrillation.

Aims: Atrial fibrillation (AF) leads to impaired exercise capacity, and catheter ablation (CA) for AF improves exercise capacity. However, the precise changes in daily activities after CA for AF remain unclear. The authors aimed to evaluate the changes in daily activities following CA for AF using a wristwatch-type pulse wave monitor (PWM), which tracks steps and exercise time, estimates burnt daily calories, and records sleep duration, in addition to establishing the rhythm diagnosis of AF or non-AF.

Impact of diabetes remission or progression on the incidence of cardiovascular disease in Japan: historical cohort study using a nationwide claims database.

Background: Previous studies demonstrated that diabetes remission can occur during intensive intervention and in real-world settings. However, the impact of diabetes remission in real-world settings on the incidence of cardiovascular disease (CVD) remains unclear.

Methods: This retrospective cohort study included 299,967 individuals aged 20-72 years who underwent multiple checkups between 2008 and 2020 and completed ≥ 3 years of follow-up.

Association of nighttime very short-term blood pressure variability determined by pulse transit time with adverse prognosis in patients with heart failure.

Long-term blood pressure (BP) variability (BPV) is associated with adverse prognosis in patients with heart failure. However, the clinical significance of very short-term (beat-to-beat) BPV is unclear. We collected data on nighttime pulse transit time-based continuous beat-to-beat BP measurement in patients with heart failure (n = 366, median age 72.
