A Real-Time Web-Based Intervention with a Multicomponent Group-Based Program for Older Adults: Single-Arm Feasibility Study.

Frailty is a growing public health challenge in Japan's rapidly aging population, where 28.8% are aged ≥ 65. While multicomponent interventions have shown potential in preventing frailty, traditional face-to-face programs face accessibility challenges.

Achieving reduced radiation exposure with maintained fluoroscopy effectiveness using ultralow-dose settings in cryoballoon ablation.

Background And Aims: Optimization of fluoroscopic image quality for reducing radiation exposure in cryoballoon pulmonary vein isolation (CB-PVI) has not yet been fully investigated. Therefore, we tried to compare the radiation doses among three different X-ray system settings.

Methods: Consecutive 148 patients scheduled for their first CB-PVI were prospectively enrolled: low dose with the use of an anti-scatter grid for the first 51 patients (LD + G group), low dose without an anti-scatter grid for the subsequent 46 patients (LD-G group), and ultralow dose (ULD group) with an anti-scatter grid for the remaining 51 patients.

Critical ablation targets of ventricular tachycardia revealed by activation mapping with both last deflection and peak frequency annotations in a patient of cardiac sarcoidosis.

Different rotation activation pattern (RAP) sites with good pacemap score were identified by activation mapping with both last deflection and peak frequency annotations. These two RAP sites were considered to be the critical ablation targets of ventricular tachycardia in cardiac sarcoidosis, which led to successful ablation without an extensive lesion.

A Community-Based Intervention to Enhance Subjective Well-Being in Older Adults: Study Design and Baseline Participant Profiles.

Promoting subjective well-being is a crucial challenge in aging societies. In 2022, we launched a community-based intervention trial (the Chofu-Digital-Choju Movement). This initiative centered on fostering in-person and online social connections to enhance the subjective well-being of older adults.

Vascular responses to a biodegradable polymer (polylactic acid) based biolimus A9-eluting stent in porcine models.

Aims: The time-dependent changes in endothelial and healing properties of coronary arteries implanted with a biodegradable polymer-based biolimus A9-eluting stent (BioPol-BES) have not been investigated. We evaluated the short-term and the long-term in vivo response of BioPol-BES, as compared to a permanent polymer-based sirolimus-eluting stent (PermPol-SES), and a bare metal stent (BMS).

Methods And Results: Overlapping stents were placed in 33 swine (n=11 for BES, SES, and BMS, respectively) for two and four weeks and single stents in 30 miniature pigs (n=18 for BES, n=9 for SES, n=3 for BMS) for three, nine and 15-month evaluations.
