Filter by:Aim of this project is to delineate sustainable physical exercise programs and to assess the effects of such programs mainly on endocrine-metabolic and neurovegetative outcomes in a cohort of men with metabolic syndrome-related late-onset central hypogonadism. Participants will undergo a personalised exercise program. After 6 months they will be subdivided into two groups, according to the weekly physical activity volume actually performed (above or below 600 MET·minutes/week). Changes in endocrine-metabolic and neurovegetative outcomes will be compared between the two groups.
Autonomic modulation by transcutaneous vagal nerve stimulation in acute ischaemic stroke requiring mechanical thrombectomy: a phase IIa, sham controlled randomised trial.
By measuring specific electrical parameters at acupuncture points that have been shown to correlate with ANS activity, the objectives of this study were to: 1) determine if CV4 has any influence on the bioelectric properties of the acupuncture meridian system, and 2) determine if CV4 affects the ANS.
Breast cancer is a chronic disease that has seen a boom in research into its treatments, improvements and effects in recent decades. These advances have also highlighted the need to use physical exercise as a countermeasure to reduce the cardiotoxicity of pharmacological treatments. Patients need a correct daily individualisation of the exercise dose necessary to produce the physiological, physical and psychological benefits. To this end, the present study will use, in a novel way in this population, heart rate variability (HRV) as a measure of training prescription. The primary objective of this randomised clinical trial is to analyse the effects of a physical exercise programme planned according to daily HRV in breast cancer patients after chemotherapy treatment. For this purpose, a 16-week intervention will be carried out with 90 breast cancer patients distributed in 3 groups (control group, conventional preprogrammed physical exercise training group and physical exercise group with HRV daily programming). Cardiorespiratory capacity, strength, flexibility, agility, balance, body composition, quality of life, fatigue, functionality, self-esteem, anxiety and depression of patients before and after the intervention will be evaluated in order to compare the effects of exercise and its programming.
This study looks to characterize autonomic nervous system dysfunction after spinal cord injury and identify the potential role that transcutaneous spinal cord stimulation may play at altering neuroregulation. The autonomic nervous system plays key parts in regulation of blood pressure, skin blood flow, and bladder health- all issues that individuals with spinal cord injury typically encounter complications. For both individuals with spinal cord injury and uninjured controls, experiments will utilize multiple parallel recordings to identify how the autonomic nervous system is able to inhibit and activate sympathetic signals. The investigators anticipate that those with autonomic dysfunction after spinal cord injury will exhibit abnormalities in these precise metrics. In both study populations, transcutaneous spinal cord stimulation will be added, testing previously advocated parameters to alter autonomic neuroregulation. In accomplishing this, the investigators hope to give important insights to how the autonomic nervous system works after spinal cord injury and if it's function can be improved utilizing neuromodulation.
Studying the causal roles of components of the renin-angiotensin-aldosterone system (including angiotensin-(1-7) (Ang-(1-7)), angiotensin-converting enzyme 2 (ACE2), Ang II, and ACE), uric acid, and klotho in pediatric hypertension and related target organ injury, including in the heart, kidneys, vasculature, and brain. Recruiting children with a new hypertension diagnosis over a 2-year period from the Hypertension and Pediatric Nephrology Clinics affiliated with Brenner Children's Hospital at Atrium Health Wake Forest Baptist and Atrium Health Levine Children's Hospital. Healthy control participants will be recruited from local general primary care practices. Collecting blood and urine samples to analyze components of the renin-angiotensin-aldosterone system (Ang-(1-7), ACE2, Ang II, ACE), uric acid, and klotho, and measuring blood pressure, heart structure and function, autonomic function, vascular function, and kidney function at baseline, year 1, and year 2. Objectives are to investigate phenotypic and treatment response variability and to causally infer if Ang-(1-7), ACE2, Ang II, ACE, uric acid, and klotho contribute to target organ injury due to hypertension.
In this randomized double-blind trial, we investigated whether externally induced left-hemispheric frontoparietal theta synchronization by multi-electrode online theta (6Hz) transcranial alternating current stimulation (tACS) would enhance the influence of a working memory training on negative symptoms of schizophrenia.
The function of the autonomic nervous system can be assessed using baroreflex sensitivity (BRS) and heart rate variability (HRV). Decreased HRV has been shown to be predictive of morbidity and mortality in diverse medical conditions such as acute myocardial infarction, aneurysmal subarachnoid haemorrhage, autoimmune diseases, sepsis and surgery. The function of the autonomic nervous system has not yet been investigated in a "pure hypovolemia" model. The aim of the current study is therefore to investigate and describe the function of the autonomic nervous system prior to, during and after reduction of blood volume in healthy blood donors.
This study looks to characterize gradients of dysfunction in the autonomic nervous system after spinal cord injury. The autonomic nervous system plays key roles in regulation of blood pressure, skin blood flow, and bladder health- all issues that individuals with spinal cord injury typically suffer. Focusing on blood pressure regulation, the most precise metric with broad clinical applicability, the investigators will perform laboratory-based tests to probe the body's ability to generate autonomic responses. For both individuals with spinal cord injury and uninjured controls, laboratory-based experiments will utilize multiple parallel recordings to identify how the autonomic nervous system is able to inhibit and activate signals. The investigators anticipate that those with autonomic dysfunction after spinal cord injury will exhibit abnormalities in these precise metrics. The investigators will further have research participants wear a smart watch that tracks skin electrical conductance, heart rate, and skin temperature, which can all provide clues as to the degree of autonomic dysfunction someone may suffer at home. The investigators will look to see if any substantial connections exist between different degrees of preserved autonomic function and secondary autonomic complications from spinal cord injury. In accomplishing this, the investigators hope to give scientists important insights to how the autonomic nervous system works after spinal cord injury and give physicians better tools to manage these secondary autonomic complications.
The aim of this study it's to analyze the relationship between autonomic nervous system balance (ANSb) and chronic pain conditions, especially in this case, non-especific chronic low back pain (CLBP). Most of physiotherapy approaches focus only in biomechanical aspects, leaving aside what kind of factors could perpetuate CLBP. Since 1985, ANSb was studied due to its potential contribution to chronic pain. Electrical stimulation, through interferential currents (IFC), it's a safe and well-known therapy used in CLBP with good outcomes regarding pain relief. The main objective of this study it's to quantify the association between CLBP and ANSb alterations. In second place, the research team aims to record the influence of IFC over pain and ANSb in those subjects.
