Filter by:The purpose of this study is to describe the variation characteristics and factors of the heart rate variability during long-distance running.
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.
Background: Stress is the critical method for survive of reacting to a condition including a threat, challenge or physical and psychological challenge. Stress either physiological or biological is an organism's response to a stressor such as an environmental condition. Stimuli that alter an organism's environment are responded to by multiple systems in the body. The hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system are major systems which the body reacts to the stress. It has been reported that cancer patients receiving chemotherapy perceived a lot of stress. It has been believed and well known that stress-related illness is one of the reasons contributing to the increase in long-term sick leave during the last decade in many countries. Purpose: The aims of this study are to evaluate the effects of aromatherapy on cancer patient receiving chemotherapy: 1) for physical effects by meridian electrical conductance, heart rate variability (HRV), vital sign, visual analogue scale (VAS) for pain; 2) for psychologic effects by State-Trait Anxiety Inventory (STAI). Materials and methods: This is a prospective, pre post comparison study. A total of 40 cancer patients receiving chemotherapy will be recruited as participants in this study. The characteristics data will be collected in all participants. Blood orange and rosewood will be chosen as the essential oils for aromatherapy in this study. Essential oils will be applied to all participants by inhalation for 30 minutes. Meridian electrical conductance, HRV, vital sign, VAS for pain, and STAI were evaluated and compared before and after aromatherapy. Expected outcomes: It is expected to understand more about the effects of aromatherapy on the meridian system, HRV and emotional status by undertaking 30 minutes session aromatherapy intervention for cancer patients receiving chemotherapy. The results may suggest aromatherapy as one of the affiliated programs of chemotherapy.
Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term monitoring (10 minutes-24 hours) have revealed lower heart rate variability (HRV) in patients with pulmonary arterial hypertension (PAH). In ASPIRE arrhythmias and heart rate variability is being assessed via long term monitoring. Currently the the loop-recorder is considered the gold standard for long-term continuous cardiac montoring. A non-invasive continuous monitoring could be of a great benefit for the patients, and could potentially contribute to treatment optimization. The study will assess apple watches as a non-invasive tool compared to to the loop recorder, which is considered as the current gold standard. Additionally, the study seeks to assess apple watches for monitoring as an independent wearable for risk assessment in PH.
During functional endoscopic sinus surgery(FESS), low-pressure anesthesia is often applied, aiming to decreased operative blood loss, and anesthetics, narcotics and antihypertensive agents are given to achieve desirable low blood pressure. However, the dose of these medications given is usually decided subjectively based on the clinical experience of the care provider, placing the patient in a risky situation of narcotics overdosing or underdosing. Therefore, here is the question: Whether intraoperative analgesia guided by an objective pain monitoring device, such as the Analgesia Nociception Index (ANI), could decrease the amount of narcotics, other anesthetic agents, and blood loss in patients undergoing low-pressure anesthesia.
To demonstrate the effect of non invasive vagus nerve (VNS) stimulation on heart rate variability and MSNA signal.
Depression is one of the most common invalidating mental disorders, ranked by World Health Organization as the single largest contributor to global disability. Current recommended treatments for depression include antidepressant medication and according to guidelines, Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT). Despite encouraging preliminary results (e.g., Matthijssen et al., 2020), Eye Movement Desensitization and Reprocessing (EMDR) therapy is not yet recognized as an effective therapy for depression by APA and NICE. The project aims to conduct a large multisite study that addresses the shortcomings of previous efficacy research on EMDR for depression. The primary aim is to evaluate the effectiveness of EMDR therapy in reducing depressive symptoms in adults with major depression as compared to CBT. Secondary aims of the study are the effectiveness of EMDR, as compared to CBT and TAU, in improving anxiety, and other symptoms. It is hypothesized that EMDR is not inferior to CBT.
Work-related stress is a public health issue. Among the multiple physical and psychological consequences of stress, increased mortality and cardiovascular morbidity seem the main concern. The thermal spa resort of Néris-Les-Bains is one of the five spa resorts in France specialized in the treatment of psychosomatic disorders. Among all these resorts proposing a thermal residential program of three weeks, only one thermal spa resort (Saujon) has a program for occupational burn-out. However, a shorter thermal spa residential program seems more compatible with professional context (availability of individuals), and focusing on work-related stress prevention (before the state of burn-out). The main hypothesis is that a short thermal spa residential program (6 days) of work-related stress prevention will exhibit its efficacy through objective measures of well-being and cardiovascular morbidity.
