“…Undoubtedly, exercise training has potent antioxidant, anti‐inflammatory and cardioprotective effects (de Sousa et al., 2017; Deus et al., 2019; Souza et al., 2018). However, the effects of RT and RT+BFR on the interplay between MPO/PON1 (specifically, related to CKD and CVD) and cardiac autonomic function in conservative CKD patients have never been studied before.…”

“…Aerobic exercise is considered an effective tool to improve redox balance and, consequently, the autonomic cardiac function in healthy individuals (de Sousa et al., 2017; Deus et al., 2019) and CVD patients (Kokkinos & Myers, 2010; Lin et al., 2015). However, the effects of resistance training (RT) on cardiovascular fitness remain unclear because there are fewer investigations focused on CKD.…”

Patients with chronic kidney disease (CKD) are prone to cardiovascular diseases secondary to abnormalities in both autonomic cardiac function and redox balance [myeloperoxidase (MPO) to paraoxonase 1 (PON1) ratio]. Although aerobic training improves both autonomic balance and redox balance in patients with CKD, the cardioprotective effects of resistance training (RT), with and without blood flow restriction (BFR), remain unknown. We aimed to compare the effects of RT and RT+BFR on antioxidant defence (PON1), pro-oxidative status (MPO), cardiac autonomic function (quantified by heart rate variability analysis) and renal function. Conservative CKD (stages 1 to 5 who do not need hemodialysis) patients (n = 105, 33 female) of both sexes were randomized into three groups: control (CTL; 57.6 ± 5.2 years; body mass index, 33.23 ± 1.62 kg/m 2), RT (58.09 ± 6.26 years; body mass index 33.63 ± 2.05 kg/m 2) and RT+BFR (58.06 ± 6.47 years; body mass index, 33.32 ± 1.87 kg/m 2). Patients completed 6 months of RT or RT+BFR on three non-consecutive days per week under the supervision of strength and conditioning professionals. Training loads were adjusted every 2 months. Heart rate variability was recorded with a Polar-RS800 and data were analysed for time and frequency domains using Kubios software. The redox balance markers were PON1 and MPO, which were analysed in plasma samples. Renal function was estimated as estimated glomerular filtration rate. The RT and RT+BFR decreased pro-oxidative MPO (RT, ∼34 ng/ml and RT+BFR, ∼27 ng/ml),

“…In this context it is interesting to note that older individuals engaged in high levels of physical activity (Puterman et al, 2010;Sjogren et al, 2014), have longer leukocyte telomeres and are biologically younger and healthier than age-matched sedentary older people (i.e., better blood pressure, autonomic balance, body composition, and lipid profile; Simoes et al, 2017;Deus et al, 2019;Sousa et al, 2019). They also have a preserved proportion of naive CD4+ cells without senescent T-cells accumulation than age-matched sedentary people (Minuzzi et al, 2018).…”

THE SARS-CoV-2 INFECTION AND IMMUNE SYSTEM We are waging a war against a deadly virus that has already resulted in the death of thousands of people worldwide (Burn-Murdoch, 2020). Against this invisible enemy, we have a sophisticated defense: our immune system. After infection, leukocytes proliferate and send signals to other immune cells to replicate and differentiate and, hence, increasing recruits to the army to combat the invaders in an attempt to ensure survival (Immunology, 2013).

“…Traditionally, the methods of analyzing HRV focuses on time domain and frequency domain analysis [ 6 , 7 , 8 ]. On one hand, time domain analysis mainly uses the standard deviation of all continuous RR intervals (SDNN), the square root of the mean of the sum of the squared of differences between continuous R-R intervals (RMSSD), the percentage of differences between continuous R-R intervals that are exceed 50ms (pNN50), and other indexes to evaluate HRV [ 9 ].…”

Obstructive sleep apnea (OSA) syndrome is a common sleep disorder. As an alternative to polysomnography (PSG) for OSA screening, the current automatic OSA detection methods mainly concentrate on feature extraction and classifier selection based on physiological signals. It has been reported that OSA is, along with autonomic nervous system (ANS) dysfunction and heart rate variability (HRV), a useful tool for ANS assessment. Therefore, in this paper, eight novel indices of short-time HRV are extracted for OSA detection, which are based on the proposed multi-bands time-frequency spectrum entropy (MTFSE) method. In the MTFSE, firstly, the power spectrum of HRV is estimated by the Burg–AR model, and the time-frequency spectrum image (TFSI) is obtained. Secondly, according to the physiological significance of HRV, the TFSI is divided into multiple sub-bands according to frequency. Last but not least, by studying the Shannon entropy of different sub-bands and the relationships among them, the eight indices are obtained. In order to validate the performance of MTFSE-based indices, the Physionet Apnea–ECG database and K-nearest neighbor (KNN), support vector machine (SVM), and decision tree (DT) classification methods are used. The SVM classification method gets the highest classification accuracy, its average accuracy is 91.89%, the average sensitivity is 88.01%, and the average specificity is 93.98%. Undeniably, the MTFSE-based indices provide a novel idea for the screening of OSA disease.
