Filter by:Cardiac autonomic neuropathy (CAN) in diabetic patients is an indicator of autonomic nervous system dysfunction and is an important marker for cardiovascular events. Very promising results have been obtained with SGLT2 inhibitors in both cardiac and renal outcomes. The aim is to examine the effects of SGLT2 inhibitor use on cardiac autonomic neuropathy, heart rate variability, sympathetic and parasympathetic nervous system parameters, and their relationship with BDNF levels, one of the neuroinflammatory markers.
In this study investigators want to examine if heart rate variability at hospital entry predicts prognosis in participants with severe disease.
The objective of this study is to monitor heart rate variability in preterm infants receiving respiratory support, including conventional mechanical ventilation, during skin-to-skin care. We hypothesize that skin to skin care will be associated with a more mature pattern of parasympathetic activity as measured by various domains of heart rate variability. Specifically, the standard deviation of the normal-to-normal interval (SDNN), the root mean squared of successive differences of normal-to-normal intervals (RMSDD), and the standard deviation of deceleration (SDDec) will decrease in infants that are receiving skin-to-skin care across all types of respiratory support compared to infants who are lying in their isolette.
This study aims to examine the relationship among cognitive fatigue, self-regulation, and academic performance.
This study aims to examine the effects of cognitive fatigue on heart rate variability and skin conductance and develop a machine learning model.
This study aims to examine whether listening to natural sounds in a noisy (traffic) environment compared to traffic noise only impacts behavioural, cognitive, affective, and physiological markers associated with attention restoration. Attention restoration will be examined as an aspect of cognitive fatigue.
Ophthalmology physicians and residents work under stress conditions during night emergency ophthalmology shifts. Under time pressure, that is a characteristic of the urgency of care, they must use all their cognitive resources to make an accurate diagnosis and to provide accurate decisions, with sometimes surgical emergency acts. In addition, in France, they work at night following by an usual day work, and they can also work 48 consecutive hours during weekends, followed by a work day … i.e. 60 consecutive hours of work … Long working hours with a short recovery time has been demonstrated to be a major factor of stress and fatigue. Even if not demonstrated on ophthalmologists, those working conditions may contribute to symptoms of mental exhaustion and physical fatigue (sleep deprivation), often accompanied by a loss of motivation at work. This may leads to a feeling of loss of time control; stress can also distort the perception of time and leads to hasty actions or delayed decision-making. The combined effects of stress, feelings of loss of time control, and fatigue necessarily have an impact on work performance and work quality, with a high risk of medical error. Moreover, prolonged stress may expose ophthalmologists to a higher risk of multiple diseases, predominantly systemic inflammation and coronary heart disease. The main hypothesis is that prolonged work (up to 60 consecutive working hours) may impact on HRV, comparatively to a typical working day.
The purpose of this study is to describe the variation characteristics and factors of the heart rate variability during long-distance running.
The aim of this study was to evaluate the impact of caffeine treatment, given either orally or intravenously, on heart rate variability in newborns. In addition, the investigators sought for a potential association between caffeine treatment and vital functions.
Background: Infertility is a serious reproductive health issue and affects 48.5 million couples worldwide. Women undergoing fertility treatment often experienced psychological distress but also social stigma that is close linked to later pregnancy outcome. Despite the advancement in assisted reproductive technology, effective interventions for reducing stress, anxiety, and depressive symptoms for infertility women remain lacking. Objectives: The objective of this proposal is to evaluate the efficacy of web-based mind-body intervention combining HRV biofeedback on the infertility women's anxiety symptoms, levels of depression, HRV function, mindful awareness, infertility self-efficacy, and pregnancy rates. Methods: We plan to conduct a randomized controlled trial on the web-based mind-body intervention combining heart rate variability biofeedback. Eligible women will be recruited and randomized into three groups. Intention-to-treat analysis and mixed regression modeling will be used to estimate the effectiveness of the interventions. Anticipatory results: Effective strategies will be determined for infertility women.
