Filter by:The tripod of OA clinical treatment is education, weight loss and exercise. A sedentary lifestyle has been characterized as an independent risk factor for cardiovascular disease. Studies have shown the inverse association between the level of physical activity and the incidence of cardiovascular disease. High Intensity Interval Training (HIIT), which consists of repeated high-intensity exercise sessions interspersed with passive recovery. Active, has been studied as a new therapeutic approach and has been shown to be effective in controlling blood pressure (BP) and arterial stiffness in treated hypertensive individuals. HIIT training has also been shown to be able to reverse the hemodynamic, metabolic and hormonal changes that are involved in the pathophysiology of essential hypertension, leading to improved arterial stiffness and BP response, endothelin-1 and nitrite / nitrate to exercise, increased cardiorespiratory fitness when compared to moderate-intensity continuous exercise in young women with a family history of essential hypertension. Six weeks of HIIT training (3 times / week) reduced body fat and waist circumference in young women. , while increasing fat-free mass, maximum running speed and aerobic fitness. Two recent studies evaluating body weight change in overweight patients have shown that HIIT training is comparable to moderate-intensity continuous exercise, but HIIT is more efficient compared to time spent training, which may facilitate the inclusion of daily routine training of patients. Previous work performed by the authors patients undergoing an education and physical activity program showed improvement in WOMAC. The investigators believe that the inclusion of an HIIT training protocol may lead to improved BP and hemodynamic variables in patients with knee osteoarthritis. To evaluate the effect of high intensity interval physical training associated with an educational program on BP, hemodynamic variables of individuals undergoing treatment for knee OA. 63 patients with knee OA will be randomized into 3 groups: interval exercise (21), continuous exercise (21) and control (21). Patients will be evaluated for BP using ABPM, arterial stiffness and endothelial reactivity by measuring carotid-femoral pulse wave velocity and quality of life using the Euroqol scale.
The most common methods for prevention of post-induction hypotension are preoperative fluid loading and vasopressors. Leg elevation induces an intrinsic transfusion of 150 mL blood from the lower limbs to the central fluid compartment. Leg elevation was previously reported by our group to decrease the incidence of maternal hypotension after spinal anesthesia for caesarean delivery. Passive leg raising was also reported to provide a stable hemodynamic profile during induction of anesthesia for cardiac surgery. Head-down position was previously reported as a useful measure for management of hypovolemia in various patient groups. No studies to the best of our knowledge had evaluated the compare both positions (leg elevation position and head-down position) during induction of anesthesia in non-cardiac surgery
Hypertensive patients have more hemodynamic instability during general anesthesia than do patients with NORMOTENSION. In this study, the investigators evaluated the usefulness of carotid ultrasound and inferior vena cervical ultrasound for predicting hypotension after induction of anesthesia in patients with hypertension.
The present study is aimed at comparing different strategies of UF profiling, dialysate sodium individualization and sodium profiling (even combining one with the other) and at evaluating the effectiveness of a new UF profile which has an ascending/descending shape. The goal of the study is to provide better dialysis tolerance and lower rates of intradialytic hypotensive events by the application of this UF profile design in combination with a neutral sodium balance.
Despite being studied less than half as frequently, autonomic dysfunction is a greater priority than walking again in spinal cord injury. One autonomic condition after spinal cord injury is orthostatic hypotension, where blood pressure dramatically declines when patients assume the upright posture. Orthostatic hypotension is associated with all-cause mortality and cardiovascular incidents as well as fatigue and cognitive dysfunction, and it almost certainly contributes to an elevated risk of heart disease and stroke in people with spinal cord injury. In addition, autonomic dysfunction leads to bladder, bowel, sexual dysfunctions, which are major contributors to reduced quality and quantity of life. Unfortunately, the available options for treating this condition, are primarily limited to pharmacological options, which are not effective and are associated with various side effects. It has been recently demonstrated that spinal cord stimulation can modulate autonomic circuits and improve autonomic function in people living with spinal cord injury. Neuroanatomically, the thoracolumbar sympathetic pathways are the primary spinal cord segments involved in blood pressure control. Recently, a pilot study has been published demonstrating that transcutaneous spinal cord stimulation of thoracolumbar afferents can improve cardiovascular function. However, some studies have shown that lumbosacral transcutaneous spinal cord stimulation can also elicit positive cardiovascular effects. Therefore, there is no consensus on the optimal strategy in order to deliver transcutaneous spinal cord stimulation to improve the function of the autonomic system, and it may be that lumbosacral (i.e. the stimulation site being used most commonly for restoring leg function is sufficient). Another key knowledge gap in terms of transcutaneous spinal cord stimulation is whether or not the current is directly or indirectly activating these spinal circuits. Last but not least, the effects of epidural spinal cord stimulation on the function of cardiovascular, bladder, bowel and sexual system in spinal cord injury have been investigated in no study yet. AIMS AND HYPOTHESES: Aim 1. To examine the effects of short-term (one session) transcutaneous spinal cord stimulation on the frequency and severity of episodes of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. These effects will be compared at two sites of stimulation. Hypothesis 1.1: Short-term transcutaneous mid-thoracic cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 1.2: Lumbosacral transcutaneous spinal cord stimulation will improve bladder, bowel, and sexual functions. Aim 2. To examine the effects of long-term (one month) transcutaneous spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction. Hypothesis 2.1: Long-term stimulation of the mid-thoracic cord will result in sustained improvements in mitigated severity and frequency of orthostatic hypotension/autonomic dysfunction that is not dependent on active stimulation. Hypothesis 2.2: Long-term lumbosacral transcutaneous spinal cord stimulation will result in sustained improvements in bowel, bladder, and sexual function that is not dependent on active stimulation. Aim 3: To examine the effects of short-term (one session) epidural spinal cord stimulation on the severity and frequency of orthostatic hypotension/autonomic dysfunction, and bladder, bowel, and sexual functions. Hypothesis 3.1: Epidural spinal cord stimulation will mitigate the severity and frequency of orthostatic hypotension/autonomic dysfunction and improve bladder, bowel, and sexual function. Hypothesis 3.3: There is no significant difference between immediate effects of lumbosacral transcutaneous spinal cord stimulation and epidural spinal cord stimulation on bladder, bowel, and sexual function. For aim 1, 14 participants with spinal cord injury and no implanted electrodes on the spinal cord will be recruited. Participants will randomly receive one-hour stimulation under each of the two stimulation conditions in a crossover manner: Mid-thoracic and Lumbosacral. For aim 2, 28 individuals with spinal cord injury and no implanted electrode will be pseudo-randomized (1:1) to one of two stimulation sites. Participants will receive one-hour stimulation, five sessions per week for four weeks. Cardiovascular and neurological outcomes will be measured before the first stimulation session and after the last stimulation session. For aim 3, 4 participants with spinal cord injury with implanted electrodes on the spinal cord will be recruited to study the immediate effects of invasive epidural spinal cord stimulation. All outcomes will be measured in two positions: a) Supine, b) ~ 70° upright tilt-test. Additionally, bowel, bladder, and sexual functions in project 2 will be assessed weekly.
Intradialytic hypotension (IDH ) is a serious and the most frequent complication of hemodialysis of the hemodialysis .Diabetes is associated with autonomic neuropathy which contribute to intradialytic hypotension
Spinal anesthesia is still the gold standard anesthetic method for elective and urgent cesarean section, the post spinal hypotension remains the most frequent complication of this procedure and is still responsible of considerable maternel and fetal morbidity. It is recommanded to prevent this post spinal hypotension with fluid coloading and prophylactic vasopressors administration. The aim of this study is to compare the efficency and the safety of norepinephrin and ephedrin prophylactic administration to reduce the incidence of post spinal hypotension in cesarean section.
