Diabetes alters cardiorespiratory dynamics: insights from short-term recurrence quantification analysis of pulse-respiration quotient Open
Introduction The Pulse-Respiration Quotient (PRQ) is considered a powerful tool for assessing dynamic interactions between cardiac and respiratory rhythms. Type 2 diabetes mellitus (T2DM) disrupts autonomic control, potentially compromisin…

Reduced maternal–fetal cardiac coupling in moderate preterm labor: a high-resolution symbolic dynamics analysis Open
This research explores maternal–fetal heart rhythm coupling (MFHRC) in full-term and moderate preterm labor using high-resolution joint symbolic dynamics (HRJSD) to identify distinct heart rate patterns indicative of physiological system c…

Variations in Heart Rate Variability and Physiological Responses during Analog Space Missions: An Exploratory Study Open
This exploratory study investigates changes in the autonomic cardiac system of young analog astronauts in a hostile, confined, and isolated environment. It uses linear and nonlinear indices of heart rate variability (HRV) during a Mars ana…

Comparison of short-term breathing rate asymmetry of preeclamptic and normotensive women in labor Open
Breathing rate asymmetry (BRA) refers to the observed disparities in the acceleration and deceleration phases of human respiration. The techniques employed to assess BRA could also be utilized in exploring hypertensive disorders like pre-e…

Optimizing Fall Risk Diagnosis in Older Adults Using a Bayesian Classifier and Simulated Annealing Open
The aim of this study was to improve the diagnostic ability of fall risk classifiers using a Bayesian approach and the Simulated Annealing (SA) algorithm. A total of 47 features from 181 records (40 Center of Pressure (CoP) indices and 7 p…

Analysis of fetal heart rate fluctuations in women diagnosed with preeclampsia during the latent phase of labor Open
Introduction Fetal heart rate variability (fHRV) is a tool used to investigate the functioning of the fetal autonomic nervous system. Despite the significance of preeclampsia, fHRV during the latent phase of labor has not been extensively …

Induced Relaxation Enhances the Cardiorespiratory Dynamics in COVID-19 Survivors Open
Most COVID-19 survivors report experiencing at least one persistent symptom after recovery, including sympathovagal imbalance. Relaxation techniques based on slow-paced breathing have proven to be beneficial for cardiovascular and respirat…

Effects of Supplemental Oxygen on Cardiovascular and Respiratory Interactions by Extended Partial Directed Coherence in Idiopathic Pulmonary Fibrosis Open
Idiopathic pulmonary fibrosis (IPF) is a chronic and restrictive disease characterized by fibrosis and inflammatory changes in lung tissue producing a reduction in diffusion capacity and leading to exertional chronic arterial hypoxemia and…
