Background: A commonly observed phenomenon is that although the players in a baseball team have received same training content and volume, their batting performance quite different. As no optimal solution exists for this problem at present, study attempted to explore potential of heart rate variability biofeedback (HRVB) reduce anxiety improve university players. Materials Methods: total 18 college were randomly divided into an experimental group control group. Both groups answered...

Diabetes mellitus is a significant risk factor for cardiovascular events and mortality in dialysis patients. The impact of different modalities on the new onset diabetes (NODM) remains subject debate. Previous studies did not adequately account critical confounding factors such as pre-dialysis glycemic status, medication use, nutritional which may influence association between modality NODM risk. We conducted retrospective cohort study 1426 non-diabetic end-stage renal disease (ESRD)...

The determination of appropriate parameters and an window size in most entropy-based measurements time-series complexity is a challenging problem. Inappropriate settings can lead to the loss intrinsic information within time series. Therefore, two parameter-free methods, namely entropy (IE) ensemble IE (eIE) are proposed this paper. eIE method requires parameters, which be easily determined through orthogonality test. approaches measure instantaneous complexity; thus, they do not require...

Abstract Insulin resistance (IR) is associated with cardiovascular disease in non-diabetic patients. The triglyceride-glucose (TyG) index, incorporating serum glucose and insulin concentrations, a surrogate marker. We investigated its association obstructive coronary artery (CAD) sex differences therein. Patients stable angina pectoris requiring invasive angiography between January 2010 December 2018 were enrolled. They divided into two groups according to TyG index. Two interventional...

The Gaussian smoothing method is shown to have a wide transition zone around the cut-off frequency selected filter given dataset. We proposed two iterative methods tighten zone: one being approximately diffusive and other strictly diffusive. first version smoothes repeatedly remaining high-frequency parts second requires an additional step further smooth resulting smoothed response in each of operation. Based on choice criterion for accuracy, factor number iterations are derived infinite...

Sub-maximal physical load (sub-max) training is optimal for athletes. However, few methods can directly assess whether sub-max. Therefore, this study aimed to identify metrics that could sub-max by predicting maximal load, helping athletes avoid the risks associated with training. Physiological data were collected from 30 participants in a bicycle incremental exercise experiment, including R-R interval (RR), stroke volume (SV), breath-to-breath (BB), and breathing rate (BR). Sample Entropy...

Heart rate variability (HRV) and pulse (PRV) have been widely used as an automatic nervous system (ANS) activities observation. Based on the timescale limitation of heart beat (for HRV) waveform PRV), one method instantaneous (iPRV) with photoplethysmography (PPG) had proposed a HRV PRV surrogate during non-stationary condition in frequency domain. In this paper, examination time-domain PPG passive leg raise (PLR) trial was studied. The 24 subjects pre-experiment resulted that iPRV are...

Chronic Obstructive Pulmonary Disease (COPD) is a common lung disease in Taiwan. People with COPD usually accompany dyspnea. When taking spirometry test, they feel tired measuring the tidal volume (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> ). Some research estimated V by using respiratory inductive plethysmography (RIP), however, movement between thoracic wall (TWM) and abdominal (AWM) might be distinct due to different symptoms...

A potential myocardial injury can be induced by intensive sporting activities, which may due to ventricular tachycardia or fibrillation when individuals continue exercise during the maximum physical loading period (the aerobic capability plateau, ACP). Herein, we conducted an incremental test with RR-interval and SV-series measurements as input output of circulatory system. Through time frequency analyses, aimed identify indicators for distinguishing normal stage (S1), last before ACP (S2),...

HRV (heart rate variability) is a general noninvasive method for indicating the activities of ANS (autonomic nervous system).The surrogate PRV (pulse variability), where variability resting PPG (photo plethysmo graphy) indicates and peripheral circulation.However, quick responses thermoregulation limb movement are restrictedly performed since beat-to-beat timescale property PRV.Recently, iPRV (instantaneous pulse has been developed to break limitation.The adopts empirical mode decomposition...

The recent surge in interest surrounds the analysis of physiological signals with a non-linear dynamic approach. measurement entropy serves as renowned method for indicating complexity signal. However, there is dearth research concerning respiratory signals. Therefore, this study employs novel known intrinsic (IE) to assess short-term changes thoracoabdominal movement patterns, measured by inductance plethysmography (RIP), during various states such resting, step test, recovery, and...

Background: Heart rate variability (HRV) has been widely applied for disease diagnosis. However, the 5 min signal length HRV analysis is needed. Method: A processing procedure very short-term photoplethysmography (PPG) fever detection and autoregulation assessment was proposed. The Time-Shift Multiscale Entropy Analysis (TSME) to instantaneous pulse time series (iPR) normalized by cumulative distribution function (CDF) of all scales calculate novel indices. total 33 subjects were recruited...

Predicting the correct timing for extubation is pivotal critically ill patients with mechanical ventilation support. Evidence suggests that failure occurs in approximately 15–20% of patients, despite their passing evaluation, necessitating reintubation. For reintubation invariably increases mortality risk and medical costs. The numerous parameters have been proposed decision-making, which constitute key predictors successful extubation, remains unclear. In this study, an extended classifier...

Mechanical ventilation is necessary to maintain patients' life in intensive care units. However, too early or late extubation may injure the muscles lead respiratory failure. Therefore, spontaneous breathing trial (SBT) applied for testing whether patients can spontaneously breathe not. previous evidence still reported 15%~20% of rate fail. The monitor only considers variables during SBT. this study measures asynchronization between thoracic and abdomen wall movement (TWM AWM) by using...

Abstract Background Insulin resistance is associated with cardiovascular disease in nondiabetic patients. The triglyceride-glucose (TyG) index, incorporating serum glucose and insulin concentrations, a surrogate marker. We investigated its association obstructive coronary artery (CAD) sex differences therein. Methods Patients stable angina pectoris requiring invasive angiography between January 2010 December 2018 were enrolled. They divided into two groups according to TyG indices. Two...

Background: Pathological albuminuria (PAU) (urinary albumin creatinine ratio [UACR] ≥30 mg/g) is an independent risk factor of cardiovascular disease. PAU more prevalent in men than women. We aimed to compare the association and early phase subclinical atherosclerosis (SA) between sexes. Methods: 1228 subjects aged 50–90 years were stratified by sex UACR (normal or PAU). SA was defined as mean carotid intima-media thickness ≥75th percentile cohort. Demographics prevalence compared...

Abstract Background : Plasma advanced glycation end products (AGEs) activates the receptor for (RAGE) and activation of RAGE is implicated to be pathogenesis type 2 diabetic mellitus patient vascular complications. Attenuating may exert a protective effect against development cardiovascular disease. Dipeptidyl peptidase-4 (DPP4) inhibitors are new class oral hypoglycemic agents treatment diabetes mellitus. Whether sitagliptin, DPP-4 inhibitor, has beneficial on calcification remains...

The American Psychiatric Association has identified Internet gaming disorder (IGD) as a potential psychiatric disorder. Questionnaires are the main method to classify high-risk IGD (HIGD) and low-risk (LIGD). However, results obtained using questionnaires might be affected due several factors. Flow can measure person's state of concentration cardiovascular signals reflect autonomic responses person. We propose observe flow scores from short scale HIGD LIGD groups assist in risk assessment....
