Filter by: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.
This study was planned to explain the relationship between heart rate variability and their sportive performance in basketball players.
Comparison studies comparing hemodynamic parameters provided by the Caretaker against respective Gold Standard references.
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.
The autonomous response of fighter and attack pilots who attend sessions in a flight simulator will be evaluated by measuring and analyzing heart rate variability (HRV).
Cardiovascular disease (CVD) exerts a significant health burden among shift workers, including police, firefighters, and emergency medical services (EMS). The unique occupational demands inherent to these professions--sleep loss, circadian misalignment, high stress, and sustained hyper-vigilance--confer increased risk for both on and off-duty cardiovascular events. Mitigating cardiovascular risks in these professions requires that we first identify robust markers and potential mechanisms of risk. Previous work suggest shift work has a negative impact on blood pressure (BP) and heart rate variability (HRV). Blunted BP dipping at night and during sleep, and reduced HRV are powerful markers of increased CVD risk. Both are linked to preclinical indicators of cardiac damage, such as presence of coronary artery calcium, left atrial enlargement, and cardiovascular-related mortality. This study will use an experimental crossover study design with three intervention conditions to test the impact of a 30 minute brief nap and a 2-hour longer nap versus no nap on BP and HRV. Outcomes of interest include blunted dipping of BP during nighttime hours and during sleep and HRV.
This study will be conducted by using two devices (Apollo and Biostrap) for monitoring of baseline physiologic variables and heart rate variability. The biostrap will be worn by residents and will monitor heart rate, heart rate variability, respiratory rate, sleep patterns, steps, etc. The Apollo is a pulse generator device aimed at modulating heart rate variability for (hopefully) reduction in stress and improving performance in and around the hospital. Resident neurosurgeons will wear the biostrap for a two week cycle and follow that with the addition of the Apollo device for heart rate variability modulation.
Improved survival of very preterm newborn population during the last decades has challenged us neonatologists to study and improve nutritional practices including vitamin D (VitD) supplementation. However, long term outcome in this aspect has not been researched in well documented preterm populations. As VitD has receptors in almost all human cells it modulates growth of many organs. Therefore I start to assess VitD supplementation practices and later health outcome (bones, teeth, muscles, heart, lungs) in two preterm population cohorts cared in Oulu University Hospital at the age of 5 years and 24 years (born 2014-2017 and 1994-1997).
Emergency medicine is a unique specialty focusing on a breadth of acute care, on demand . Shift work is also a fundamental component of emergency medicine, and is associated with chronic stress, including stress at work. Consequently, stress may lead to symptoms of mental exhaustion, physical fatigue, detachment from work, and feelings of diminished competence . Emergency physicians (EPs) are exposed to a complex interplay between stress (life-and-death emergencies - a defining characteristic of their job), sleep deprivation, and fatigue due to repeated changes in, and duration of shifts. Work-related exhaustion can lead to various physical and psychological symptoms, and also may be associated with delayed decision-making . The combined effects of stress and fatigue can impact on job performance, often resulting in otherwise preventable medical errors. Moreover, prolonged stress may expose EPs to a higher risk of multiple diseases, predominantly systemic inflammation and coronary heart disease. All these contribute to the premature departure of EPs to other specialties. Furthermore, low HRV has been associated with stress, burnout, and is linked with an increased risk of cardiovascular diseases. This project proposes to evaluate if life-and-death emergencies or specific situations will induce abrupt changes in HRV among emergency physicians. Moreover, we would like to compare reactions between being an actor (EPs) and being a spectator and assess the role of expertise and habituation to stressful emergency situations.
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.
