NCT07470229
This study examines how individuals respond to performance-related tasks and whether a non-invasive ear stimulation device influences stress responses during those tasks. Participants will be randomly assigned to use either an active or inactive (placebo) version of a transcutaneous vagus nerve stimulation (tVNS) device during a laboratory session. The study includes two task conditions. In one condition, participants will prepare a brief speech under evaluative conditions designed to induce stress. In the other condition, participants will complete a non-evaluative writing task. During the session, participants will wear a heart rate monitor and complete short questionnaires assessing their current feelings, including state anxiety. The primary objective is to determine whether active tVNS is associated with lower state anxiety during a performance-related stress task compared to placebo stimulation. Secondary outcomes include heart rate and task-related responses. The study will also examine whether individual differences in stress reactivity influence responses to stimulation. Participation involves one laboratory session lasting approximately 45 minutes.
NCT07463222
Febrile seizures are the most common seizure type in early childhood and usually occur during febrile illnesses. Although most febrile seizures are benign, the biological stress response during seizures is not fully understood. In particular, changes in thyroid hormones and stress-related hormones released by the sympathetic nervous system may play a role in seizure characteristics and clinical outcomes. This prospective observational study aims to evaluate the neuroendocrine response in children presenting with febrile seizures by measuring serum thyroxine (T4), epinephrine, and norepinephrine levels. These measurements will be obtained during the acute phase after seizure cessation and compared with levels measured at recovery and with febrile children without seizures. The study will examine the relationship between neuroendocrine marker levels and seizure characteristics such as seizure duration and recurrence, as well as clinical outcomes including length of hospital stay and need for pediatric intensive care unit admission. By improving understanding of the hormonal stress response associated with febrile seizures, this study aims to contribute to the knowledge of seizure pathophysiology in childhood and may help identify biological factors associated with more severe clinical courses.
NCT07453537
This randomized, double-blind, placebo-controlled clinical trial evaluates whether 70 days of daily cranberry juice consumption improves cognitive performance and motor accuracy and reduces psychological and physiological stress responses during a motor-cognitive dual-task multitasking challenge in healthy adults aged 30-55 (Aim 1). It is hypothesized that chronic cranberry juice intake will enhance dual-task performance and attenuate stress reactivity (Hypothesis 1). It is further hypothesized that cranberry juice will mitigate multitasking-related fatigue, mood fluctuations, and cognitive impairment, accompanied by favorable changes in circulating stress biomarkers and stress-regulatory neurochemical pathways (Aim 2/Hypothesis 2). Finally, the study incorporates gut analysis to determine whether cranberry juice induces beneficial shifts in the gut microbiota and microbial metabolites (e.g., SCFAs) and whether these changes are associated with improved cognitive and stress-related outcomes, consistent with a microbiome-gut-brain axis mechanism (Aim 3/Hypothesis 3).

The intervention involves the use of an eye mask and earplugs to reduce environmental stimuli. The study will comparatively assess the effects of sensory isolation on anxiety levels and physiological parameters, including blood pressure, heart rate, and oxygen saturation.
NCT07324863
This study aims to evaluate the efficacy of ultrasound-guided external oblique and rectus abdominis plane block on the neuroendocrine stress response and postoperative analgesia in adults undergoing umbilical hernia repair.
NCT07303088
The goal of this clinical trial was to learn if supplementation with L-carnitine or Coenzyme Q10 improves effectively the oxidative stress markers in adult patients undergoing chronic hemodialysis. It was also to evaluate the basic oxidative profile of hemodialyzed patients and to learn about the safety and tolerability of the two supplements. The main questions it aimed to answer are: * Does tunisian hemodialyzed patients have a severe oxidative status? * Does L-carnitine and Coenzyme Q10 significantly reduce oxidant markers and improve endogenous antioxidants compared to placebo? * Are the positive effects of L-carnitine and Coenzyme Q10 on oxidative stress maintained after a period of wash-out ? * Are L-carnitine and Coenzyme Q10 supplementation safe and well-tolerated in hemodialyzed patients? Researchers had compared the effects of the two supplements to identical placebos. Oxidative parameters were dosed at baseline, after 12 weeks of supplementation, and after 12 weeks of wash-out. Participants had: * taken one of the active molecules or a placebo for 12 weeks. * been followed-up for 12 more weeks of wash-out after the end of the cure. * a monitoring by hebdomadary sheets in each hemodialysis session, that recorded the medication taken the day of the hemodialysis session and the day before, errors and forgetfulness of the medication, as well as any incidents or adverse events, and monthly visits to monitor patient safety, compliance, and collect key clinical data including blood pressure, dry weight, and specific laboratory tests like hemoglobin and thyroid function, all of which were recorded in the Case Report Form (CRF).
NCT07300878
In general anestheisa airway is secured by passing a tube down the widpipe. This helps the patient to breath via ventilator during anesthesia. For placing this tube laryngoscopy is done which results in increase in blood pressure and heart rate. This study will compare the rise in blood pressure and heart rate among when using video laryngoscope with conventional laryngoscope.
NCT06166186
It has been reported that non-pharmacological methods can be used as an alternative in addition to pharmacological methods to reduce pain, anxiety, stress and inflammatory response that begins with the surgical incision in the intraoperative period and continues throughout the operation. It has been reported that music can be used as an alternative non-pharmacological method to reduce pain and anxiety in the perioperative period, as well as surgical stress and the related stress response. The aim of this study is to test the hypothesis that music used as a non-pharmacological method in the intraoperative period can reduce inflammatory response in living donor hepatectomy.
NCT07007754
This randomized kontrolled study is aimed to contribute to the literature on recognising, evaluating and reducing stress in the intensive care unit, which is one of the main responsibilities of surgical nurses, and to increase awareness on the subject.
NCT06923436
The psychological well-being of healthcare workers in hospital settings is a topic of growing interest in the scientific literature, given the crucial importance of their role in ensuring high-quality care. In addition, the Covid-19 pandemic health emergency has further accentuated the relevance of this issue, increasing anxiety and stress levels, testing the resilience and resistance of those working in care settings, revealing and highlighting how the accumulation of work-related stress can result in disabling pathologies for the caregiver, with an inevitable impact on the facility and care in general. Recent studies show that health care workers are particularly vulnerable to work-related stress, which can result from various factors such as high work demands, emotional pressure, irregular shifts, and interactions with critically ill patients. Burnout syndrome, characterized by emotional exhaustion, depersonalization and reduced personal accomplishment, is widely documented among hospital staff. Research indicates that burnout not only compromises the psychological health of healthcare workers, but also negatively affects the quality of care provided by increasing the risk of medical errors. In light of these factors, it is crucial to deepen our understanding of the dynamics that influence psychological well-being and work-related stress in health care workers in order to develop effective interventions that can improve their quality of life and consequently the quality of care provided to patients. Preliminary assessment of the emotional burden and motivational aspects of health care workers (showing what very often eludes a first glance, making visible something that is often invisible), along with effective stress management, would allow for greater ability to remain calm under pressure, reduced frustration, increased ability to make informed decisions, and to communicate effectively with patients and colleagues. These aspects translate into an image of a safer and more caring health care system in promoting better quality of care. The aim of this project is to highlight the importance of psychological wellbeing for those working in health care settings and to promote attention to this area, also with a view to identifying possible interventions aimed at identifying preventive and protective factors in relation to health care workers. The aim, therefore, is to show what is very often invisible at first sight, to make visible what is invisible: to explore, accommodate and contain areas of criticality and fragility in the context of work in health care settings, working on interventions aimed at the psychological well-being of workers.

NCT06631534
The aim of this randomized trial is to determine efficacy of dexmedetomidine in improving quality of recovery in pediatric patients undergoing interventional catheter closure of ASD while maintaining the hemodynamic parameters. Additionally he stress reducing effects of dexmedetomidine will be investigated in this population . The main questions it aims to answer are: Does Dexmedetomidine maintain stable hemodynamics in pediatric patients undergoing transcatheter ASD Closure while improving their quality of recovery? Does dexmedetomidine prolong duration of recovery and time to extubation in pediatric patients ? Does dexmedetomidine exert stress reducing properties in this population? Participants will: Either be administered Dexmedetomidine in a loading/maintenance regimen or a placebo, with hemodynamics being monitored at the baseline, intraoperatively and postoperatively, with recovery time and quality of recovery especially emergence delirium being monitored. Stress hormone levels will be sampled at baseline and postoperatively.
NCT06097182
The study aims to evaluate the sub-chronic effects of colonic delivery of a post-biotic on stress response, mood state, sleep, and cognition in healthy young subjects with elevated self-reported stress levels. It is hypothesized that oral intake of the post-biotic, when released in the colonic intestinal site, leads to a blunted subjective and objective stress response after a stress induction.
NCT06169475
Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Some researchers proposed that the dysregulated response or organ dysfunction can be lessened by reducing the stress response, which further reduce complication and mortality rates of sepsis. Dexmedetomidine is alpha adrenergic receptor agonist, presenting sympatholytic action in certain parts of the brain with anxiolytic, sedative, and pain killing effects. In the experiments of sepsis animal model, dexmedetomidine have been proved to improve serum lactate clearance and the microcirculation. Dexmedetomidine may inhibit inflammation, as it enhances the activity of the immune system while reducing its systemic reaction and lowering cytokine concentrations. There are also evidences in clinical trials with definite safety that dexmedetomidine reduced inflammation, reduced vasopressor requirements and improved organ function. The beta antagonist esmolol has been proposed as a therapy to lower heart rate, thereby improving diastolic filling time, and improving cardiac output, resulting in a reduction in vasopressor support. A recent meta-analysis of 8 randomized studies using esmolol suggested that the 32% risk ratio decreased 28-day mortality, and a meta-analysis of 7 studies using esmolol in patients with sepsis and septic shock was associated with 32% lower 28-day mortality. However, the effect of anti-stress drugs on cerebral hemodynamics is unknown. In this study, investigators are going to apply the technique of transcranial Doppler to assess the reaction of cerebral blood flow in anti-stress group and control group.
NCT03378674
Perioperative adequate analgesia reduces neuroendocrine stress response and postoperative complications. Because opioids are the most effective parenteral drugs to control pain and stress response, in this prospective randomized double-blinded controlled study we supposed that higher dose of remifentanil may reduce stress marker variations compared to lower dose in patients undergoing laparoscopic cholecystectomy.
NCT03288610
The purpose of this study is to find a preoperative biomarker before cardiac surgery with cardiopulmonary bypass related to severe postoperative inflammatory response and circulatory complications. The investigators hypothesize that an increase of the preoperative stimulation of vasopressinergic system (in response to acute or chronic conditions) could lead to a microcirculatory dysfunction and favor the occurrence of vasodilatation during and after CPB and increase the symptoms of an inflammatory response after CPB. By defining a high risk population, a targeted strategy of monitoring and early or preventive treatment could improve postoperative prognosis.
NCT01128088
Keyhole bowel surgery provides the patient with an improved outcome following surgery in comparison to more traditional surgery requiring a large cut. In order to further improve outcomes there are several variables that must be controlled before, during and after the operation. These variables are the correct pain relief, accurate control and measurement of the fluid that is given during the operation and the subsequent mobility following surgery. Previous research has already identified that an enhanced recovery program (careful control and structure to the patients journey) will reduce the length of stay and complications after an operation. Currently an integral part of the enhanced recovery program requires the use of an epidural (a thin tube in the spine) to provide continuous pain relief for up to 48 hours. Through research previously undertaken at the MATTU the investigators have shown that an epidural can lead to an increase in the length of stay and a delay in the return to normal bowel function. A reason for the use of an epidural is to suppress the stress response. The investigators aim to recruit patients from outpatient clinic undergoing keyhole bowel surgery in one unit and randomize them to receive one of two different pain relief methods after the operation. Patients will follow the same care as standard patients but their pain relief will differ between two already well established modalities. They will also receive different intravenous fluids. Blood will also be drawn at various intervals immediately after the operation for future analysis. The trial will be funded by the MATTU and will run for approximately 18 months. This trial will enable us to establish the stress response in the four groups and correlate it to the patient's outcome with an aim to refining the enhanced recovery program.
