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 compromising the complexity adaptability of cardiorespiratory dynamics. In this cross-sectional, exploratory study, we investigated whether T2DM alters dynamics by analyzing short-term PRQ signals using conventional linear indices Recurrence Quantification Analysis (RQA)....
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 respiratory dynamics in healthy subjects patients with various diseases. Therefore, the present study aimed explore cardiorespiratory by linear nonlinear analysis of photoplethysmographic time series under a psychophysiological assessment that includes breathing....
Introduction Fetal heart rate variability (fHRV) is a tool used to investigate the functioning of fetal autonomic nervous system. Despite significance preeclampsia, fHRV during latent phase labor has not been extensively studied. This study aimed evaluate cardiac activity by using linear and nonlinear indices analysis in women diagnosed with preeclampsia without hypertensive treatment gestation, compared normotensive labor. Methods A cross-sectional exploratory was conducted among pregnant...
The aim of this study was to improve the diagnostic ability fall risk classifiers using a Bayesian approach and Simulated Annealing (SA) algorithm. A total 47 features from 181 records (40 Center Pressure (CoP) indices 7 patient descriptive variables) were analyzed. wrapper method feature selection SA algorithm applied optimize cost function based on difference mean minus standard deviation Area Under Curve (AUC) across multiple dimensions. stratified 60-20-20% hold-out used for train, test,...
Abstract 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 rate patterns indicative of physiological system couplings during active stages. study evidences that exhibits unique MFHRC compared labor, potentially reflecting responses complexities differences. The analysis involved 25 RR time series from women 18 those labor. HRJSD was utilized dissect the degree...
Idiopathic pulmonary fibrosis (IPF) is a chronic and restrictive disease characterized by inflammatory changes in lung tissue producing reduction diffusion capacity leading to exertional arterial hypoxemia dyspnea. Furthermore, clinically, supplemental oxygen (SupplO2) has been prescribed IPF patients improve symptoms. However, the evidence about benefits or disadvantages of supplementation not conclusive. In addition, impact SupplO2 on autonomic nervous system (ANS) regulation respiratory...
Interstitial lung diseases (ILDs) have been increasing their relevance in loss of lives according to a recent world wide medical information. Idiopathic pulmonary fibrosis (IPF) and combined emphysema syndrome (CPFES) belong ILD class with the latter having limited survival prognosis. In clinical environment high resolution computed tomography (HRCT) is used detect CPFE; however, there still controversy about amount observed HRCT declare CPFES. Consequently, help diagnosis CPFES develop an...
This exploratory study investigates changes in the autonomic cardiac system of young analog astronauts a hostile, confined, and isolated environment. It uses linear nonlinear indices heart rate variability (HRV) during Mars mission to assess how HRV varies under day night stressors. is guided by hypothesis that significant occur based on adaptation days, aiming offer insights into nervous (ANS) environmental Over five days August 2022, faced adverse conditions Mojave Desert, simulating...
Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease that can lead to chronic arterial hypoxemia, hypercapnia, and dyspnea. To improve clinical symptoms in IPF patients, supplemental oxygen (SupplO2) has been prescribed with the aim maintain SpO2 level, consequently relieve dyspnea, increase physical activity quality of life. In this study, we investigated effect short-term SupplO2 on cardiovascular respiratory autonomic regulation. Linear nonlinear indices were...
