Summary: This study examined the effects of urban environments on the Autonomic Nervous System (ANS) and found that the effects of green areas are immediate, while those of urban environments are gradual. There are ethnic differences in the ANS adaptation among Arab and Jewish women in different environments.

Summary: The aim of this study was to analyze the effects of CHF on brain activity through EEG complexity measures. The results showed significant differences between CHF patients and healthy elderly individuals in the total spectrum and theta frequency band of the EEG. Within the CHF group, correlations were found between EEG parameters and clinical data such as BNP and NYHA scores. These findings suggest similarities between EEG abnormalities in CHF and cognitive impairment.

Summary: Assessment of heartbeat dynamics can be used for non-invasive monitoring of cardiovascular and autonomic states. However, the non-specificity of such measurements limits their applicability in naturalistic conditions. In this study, we investigate the irregularity and complexity of cardiac sympathetic and vagal activity series in different populations. Our results show significant differences between pathological/old subjects and young subjects, providing new insights into physiology and improving the specificity of heartbeat-derived biomarkers.

Summary: We conducted a systematic review and meta-analysis to explore the impacts of stimulant and non-stimulant medications on autonomic functioning in individuals with ADHD. We searched multiple databases for relevant studies and included a variety of measures for autonomic activity. The findings suggest that both stimulants and non-stimulants can increase heart rate and blood pressure in individuals with ADHD, and stimulant use is associated with increased arousal as indicated by electrodermal activity and pupil diameter. However, the diverse methodologies employed in the included studies highlight the need for more standardized and rigorous research to fully elucidate the relationship between arousal, medication, and behavior in ADHD.

Summary: The study found that subjective GWI symptom severity scores were related to objective measures of autonomic nervous system activity. Higher PNS activity was associated with lower symptom severity, while higher SNS activity was associated with higher symptom severity.

Summary: This study examined the effect of music stimulation on fetal heart rate and autonomic nervous system activity. The results showed that music stimulation can enhance fetal heart rate variability without changing the mean value of fetal heart rate. This effect is mainly attributed to the activation of the parasympathetic nervous system, indicating that music can induce a state of relaxation in the fetus.

Summary: There is a bidirectional relationship between poor sleep and mood-and anxiety-related disorders, and both are independently associated with altered autonomic nervous system (ANS) function. Heart rate variability (HRV) can reflect ANS dysregulation during sleep, which may play a mediating role in the association between poor sleep and mood-and anxiety-related disorders.

Summary: This study investigates the development of premature infants' autonomic nervous system through quantitative analysis of heart-rate variability and examines the role of heart-rate drops in relation to sympathovagal indices. The research demonstrates that maturation models based on HRV have comparable performance to other models, with selected features showing predominance in explaining infants' sympathovagal development. Additionally, bradycardias may disrupt the relationship between common temporal indices of the tachogram and the age of the infant and the interpretation of sympathovagal indices.

Summary: This study investigated the effects of different doses of the chemotherapeutic drug doxorubicin on physiological parameters and autonomic function in rats. The results showed a positive correlation between doxorubicin dose and blood pressure, heart rate, urinary norepinephrine, LF/HF ratio, and fibrotic heart area. Higher doses of doxorubicin resulted in hypotension, bradycardia, and a decrease in the balance of autonomic activity (LF/HF), with 16 mg/kg being the threshold dose at which these changes became evident. These findings highlight the importance of knowing the correct dosage of doxorubicin to minimize its adverse effects on the heart and improve treatment strategies for cancer patients.

Summary: Heart rate variability (HRV) has the potential to predict cognitive performance, and higher HRV is associated with better neurocognitive performance measures. Blue-collar and white-collar workers show differences in their correlations and sometimes exhibit opposite relationships with the same variables. The findings highlight the importance of assessing task-dependent HRV parameters.

Summary: This study proposes an alternative approach to analyzing the effects of Chinese Chi meditation and Kundalini yoga on cardiac dynamics using 'HRVGAN'. The approach augments the dataset of HRV signals and analyzes them directly without the need for signal conversion. The results indicate that meditation significantly affects cardiac dynamics, and the choice of meditation technique leads to different changes. The proposed HRV-GAN model achieves high sensitivity and accuracy, making it beneficial for automated analysis of HRV signals with limited data samples.

Summary: The study found that individuals with Duchenne Muscular Dystrophy (DMD) receiving Prednisolone therapy showed cardiac autonomic function comparable to the typically developed control group, while those receiving Deflazacort therapy had lower cardiac autonomic function. Corticosteroids have the potential to affect the cardiac autonomic modulation in adolescents with DMD, with Prednisone/Prednisolone promoting improved responses in sympathovagal activity compared to Deflazacort.

Summary: Frequent extreme cold events have posed serious threats to outdoor workers and rescuers. This study investigates heart rate variability (HRV) and its relationship to other physiological parameters under extreme cold exposures. The results show that temperature decrease is accompanied by progressive parasympathetic nervous system (PNS) activation with sympathetic nervous system (SNS) retraction. SDNN is found to be the most sensitive HRV index, showing good linear relationships with blood pressure, pulse, and hand temperature.

Summary: The heart and brain are interconnected and communicate with each other for homeostatic regulation. The neurovisceral integration model proposes that heart rate variability can indicate the functional integrity of cognitive neural networks. There is a significant alteration in heart-brain interaction in patients with refractory epilepsy.
