Summary: This study found that autonomic dysfunction, including sympathetic, parasympathetic, or both, may occur in COVID-19 patients in the early phase of infection, with significantly higher proportions in the severe and mild groups compared to healthy controls. Therefore, cardiovascular autonomic neuropathy should be taken into consideration in the assessment of COVID-19 patients.

Summary: This study investigated the modulation of dopamine on monosynaptic reflex in different segments of the spinal cord, showing that dopamine leads to facilitation of reflex in segments containing intermediolateral nucleus, while inhibiting in sensorimotor segments. The differential responses observed in autonomic nervous system segments may be due to the presence of gap junctions in the intermediolateral nucleus.

Summary: Parental socialization may influence the development of children's autonomic nervous system, particularly the parasympathetic nervous system. A meta-analysis revealed that positive parenting is positively associated with higher resting parasympathetic nervous system activity in children. This association is more pronounced in experimental studies and when the sample includes children with a clinical condition.

Summary: This paper developed a computational model that incorporates the intrinsic cardiac nervous system into the computational model of blood pressure regulation. The central and local contributions to the control of heart rate, ventricular functions, and respiratory sinus arrhythmia were studied. The simulations matched the experimental observations and predicted the relative contributions of sensory and motor neuron pathways to heart rate changes. This closed-loop cardiovascular control model is important for evaluating bioelectronic interventions to treat heart failure and renormalize cardiovascular physiology.

Summary: Multiple sclerosis (MS) is a chronic progressive disease affecting both the central nervous system (CNS) and autonomic nervous system (ANS), leading to a range of urological, sexual, gastrointestinal, cardiovascular, and thermoregulatory disorders as well as increased fatigue. The manifestations of ANS dysfunction in MS are often underestimated due to the non-specificity of symptoms and limited evaluation in clinical practice. The underlying mechanisms causing these disorders have yet to be fully investigated, hindering targeted etiological treatment. Early diagnosis and individualized treatment regimens, incorporating multiple approaches, have shown the best results in managing ANS dysfunction in MS patients.

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: The cardiovascular response to exercise is regulated by neurocirculatory control mechanisms, including central command, baroreflex, exercise pressor reflex, and arterial chemoreflex. These mechanisms modulate autonomic nervous system activity, influencing cardiac output and vascular resistance to ensure adequate blood flow to active muscles and organs. The interaction of these mechanisms has recently gained recognition for its impact on circulation, especially in unique environments such as high altitude.

Summary: This systematic review examines the use of local analgesics, specifically lidocaine or bupivacaine, to prevent autonomic dysreflexia (AD) in individuals with spinal cord injury (SCI). The review finds that lidocaine has a beneficial effect on AD in some studies, but the small sample sizes and conflicting results highlight the need for larger, well-monitored clinical trials.

Summary: This study found that autonomic dysreflexia (AD)-associated heart rate changes during penile vibrostimulation (PVS) and urodynamic studies (UDS) appear to be related to the magnitude of systolic blood pressure increases. Highly elevated systolic blood pressure with bradycardia suggests the presence of severe AD. Cardiovascular monitoring and early detection of AD are recommended during PVS and UDS to reduce the risk of life-threatening complications.

Summary: Multiple studies have shown that epidural spinal cord stimulation (eSCS) can restore volitional motor control in participants with motor-complete spinal cord injury (SCI). However, there has been a lack of rigorous quantitative descriptions of muscle coordination. In this study, six participants with chronic SCI underwent a brain motor control assessment (BMCA) to investigate the impact of eSCS on muscle activity complexity and muscle synergies. Results showed that eSCS immediately reduced muscle activity complexity and improved coordination between muscle groups over time. Muscle synergies were also restored with eSCS, supporting the neural hypothesis of muscle synergies.

Summary: Spinal cord injury (SCI) leads to severe cardiovascular dysfunction, and autonomic dysreflexia (AD) is one of the causes of high blood pressure in SCI patients. Recently, spinal cord stimulation (SCS) has been considered as a potential intervention to alleviate unstable blood pressure after SCI. This case series demonstrates the real-time effect of epidural SCS (eSCS) at the lumbosacral spinal cord in mitigating AD in individuals with SCI.

Summary: Despite the common practice of catheter reuse in individuals with spinal cord injury (SCI), there is a risk of developing catheter-associated urinary tract infections (CAUTI). This study investigated the microbiological burden and surface changes of reused catheters in the short term. The results showed the presence of bacterial biofilm and antibiotic-resistant bacteria on all reused catheter surfaces, as well as asymptomatic bacteriuria in the majority of participants. These findings suggest that short-term catheter reuse may increase the susceptibility to CAUTI in SCI individuals.
