Autonomic Nervous System Activity before Atrial Fibrillation Onset as Assessed by Heart Rate Variability.

Background: Neuromodulation has been shown to increase the efficacy of atrial fibrillation (AF) ablation procedures. However, despite its ability to influence the autonomic nervous system (ANS), the exact mechanism of action remains unclear. The activity of the ANS via the intracardiac nervous system (ICNS) can be inferred from heart rate variability (HRV).

How can the reform of the activity-based payment system (T2A) help in financing innovative health products?

In France, the short-stay activities of public and private sector healthcare facilities have been financed since 2004 by activity-based pricing (T2A). The principle is to allow for payment determined primarily by the nature and volume of activities. T2A has enabled a major transformation compared to the old financing system, chiefly for public sector facilities that used to operate under a general allocation, and convergence between payment methods in the public and private sectors.

In Vitro Modulation of Human Foam Cell Formation and Adhesion Molecules Expression by Ginger Extracts Points to Potential Cardiovascular Preventive Agents.

Recent findings from the World Heart Federation (WHF) reported a significant increase in cardiovascular disease (CVD)-related deaths, highlighting the urgent need for effective prevention strategies. Atherosclerosis, a key precursor to CVD, involves the accumulation of low-density lipoprotein (LDL) and its oxidation within the endothelium, leading to inflammation and foam cell formation. Ginger extracts, known for their antioxidative and anti-inflammatory properties, show promise in preventing CVD initiation by inhibiting LDL oxidation and reducing foam cell formation.

Methods: We enrolled 250 patients with a 40%-80% LM stenosis in a prospective, multicenter registry. These patients underwent both iFR and FFR measurements.

[Long COVID : which neuropsychological intervention ? The example applied at the Leenaards Memory Centre].

A "Long COVID" care management was created at the Leenaards Memory Centre (Lausanne University Hospital) to meet the high demand for neuropsychological examinations in the patients which have persistent symptoms for several months. A multidisciplinary evaluation specifically addressing aspects of fatigue and sleep as well as cognition has been developed to receive these patients. Depending on the severity of their symptoms, they are then oriented towards a holistic group treatment, integrating cognitive remediation including psycho-education, restorative and compensatory methods to cope with their cognitive difficulties, and tools to manage the various symptoms of COVID-long (fatigue, insomnia, stress, depression and reduced quality of life).

High Fidelity Pressure Wires Provide Accurate Validation of Non-Invasive Central Blood Pressure and Pulse Wave Velocity Measurements.

Central blood pressure (cBP) is known to be a better predictor of the damage caused by hypertension in comparison with peripheral blood pressure. During cardiac catheterization, we measured cBP in the ascending aorta with a fluid-filled guiding catheter (FF) in 75 patients and with a high-fidelity micromanometer tipped wire (FFR) in 20 patients. The wire was withdrawn into the brachial artery and aorto-brachial pulse wave velocity (abPWV) was calculated from the length of the pullback and the time delay between the ascending aorta and the brachial artery pulse waves by gating to the R-wave of the ECG for both measurements.

Background: The use of serious games in health care is on the rise, as these games motivate treatment adherence, reduce treatment costs, and educate patients and families. However, current serious games fail to offer personalized interventions, ignoring the need to abandon the one-size-fits-all approach. Moreover, these games, with a primary objective other than pure entertainment, are costly and complex to develop and require the constant involvement of a multidisciplinary team.

Autonomic nervous system assessment using heart rate variability.

The role of the autonomic nervous system in the onset of supraventricular and ventricular arrhythmias is well established. It can be analysed by the spontaneous behaviour of the heart rate with ambulatory ECG recordings, through heart rate variability measurements. Input of heart rate variability parameters into artificial intelligence models to make predictions regarding the detection or forecast of rhythm disorders is becoming routine and neuromodulation techniques are now increasingly used for their treatment.

Towards more personalized digital health interventions: a clustering method of action and coping plans to promote physical activity.
