Summary: This study used machine learning to estimate participants' age based on autonomic cardiovascular indices. The Gaussian process regression model was found to be the most suitable, with a correlation of r=0.81 and a mean absolute error of MAE=5.6 years. The estimated age for obese participants was significantly higher compared to normal-weight controls, indicating advanced cardiovascular aging by 5.7 years.

Summary: This study aims to verify the influence of beta-blockers or angiotensin receptor blockers on cardiovascular responses to exercise training in hypertensive post-menopausal women. The findings show that angiotensin receptor blockers have a pronounced effect on awake ambulatorial systolic blood pressure, while beta-blockers users have greater effects on blood pressure variability. Additionally, exercise can mitigate blood pressure reactivity to stress with no differences between groups. However, there were no major differences in heart rate variability.

Summary: In this study, we investigated how various cardiorespiratory parameters respond to acute mental stress by utilizing multi-modal physiological signals and wearable-based sensing platforms. The results showed that the cross-integration of these signals can provide effective signatures to elucidate the collective physiological changes during acute mental stress. This work demonstrates the proof-of-concept of tracking acute mental stress through physiology-inspired signatures derived from multi-modal physiological signals, paving the way for future research in quantifying stress responses in real-world settings.

Summary: Floatation-REST reduces anxiety levels and increases interoceptive awareness for cardiorespiratory sensations in anxious patients. The intervention lowers blood pressure, breathing rate, and certain metrics of heart rate variability, indicating a shift toward a more parasympathetic state of the autonomic nervous system.

Summary: This study found that there is no significant association between chronic coffee consumption and blood pressure changes, particularly when assessed through 24-hour ambulatory and home blood pressure monitoring. However, consuming coffee during the day can cause a slight increase in blood pressure, which disappears at night.

Summary: In this study, PPGI sensors were mounted on a robot for active and autonomous HR estimation. A proposed algorithm simplified the extraction of facial skin images and selected pixels based on the most frequent saturation value to achieve accurate HR assessment. The algorithm was validated on two datasets, demonstrating high accuracy and processing efficiency.

Summary: The cardiovascular benefits of particulate-filtering respirators (PFRs) remain unclear. A systematic review and meta-analysis of randomized studies were conducted to evaluate the effects of wearing PFRs on blood pressure and heart rate variability. The analysis showed modest or non-significant improvements in blood pressure and some heart rate variability parameters from wearing PFRs over short periods. However, these findings are limited by the small number of trials and variations in experimental designs and durations.

Summary: In this study, intra-fraction tumor motion in early stage breast cancer patients receiving neoadjuvant stereotactic ablative radiotherapy was quantified using implanted fiducial markers and image guidance. Results suggest that a 5 mm PTV margin is sufficient for most patients, especially in the inferior/superior and anterior/posterior directions, but further immobilization or a larger margin may be necessary for the left/right direction.

Summary: This study investigated the impact of vestibular-specific electric fields on manual pointing accuracy in high ELF-MF environments. The results suggest that even at high levels, ELF exposure is not able to modulate hand pointing performance in humans. This provides useful knowledge for the safety and performance of workers in high ELF-MF environments.
