Filter by:The primary purpose of this study is to characterize cardiovascular autonomic function to emotional stimuli (blood-injection-injury phobia [needle phobia]) during an orthostatic (upright) challenge in individuals with and without known needle phobia. It is well established that emotional stress can produce hypotensive (low blood pressure) reactions. Interestingly, these hypotensive reactions to venipuncture (even with minimal blood drawn), insulin injections, finger sticks for blood sugar monitoring, dental care, and vaccinations can affect up to a quarter of adults and appear to be uniquely associated with blood-injection-injury phobia rather than other phobias. These hypotensive reactions can ultimately lead to a vasovagal syncope (fainting) response, and lead to increased avoidance of medical and dental procedures as a result of this phobia. Ultimately, this has severe implications on public health and places additional strain on the Canadian healthcare system. Currently, there is limited understanding surrounding the initiation of this response. Additionally, a comprehensive profile of cardiovascular autonomic function during exposure to provoking stimuli during orthostatic stress has not been captured in the literature. We will test individuals with and without blood-injection-injury phobia using our standard approach while exposing them to emotional stimuli.
Background: Radiotherapy is a mainstay of treatment for ENT cancers, and its indication is frequent. Patients are positioned and immobilized using a thermoplastic mask, which is attached to the treatment table for the duration of each daily treatment. The mask's purpose is to prevent patient movement and ensure reproducible positioning. The advantages of using thermoplastic masks come at a cost for many patients. It is well established that mask fixation and mask anxiety are major concerns for patients, adversely affecting their quality of life and hindering treatment compliance. Surface-guided radiotherapy (SGRT) enables patients to be positioned and their movements monitored in real time during treatment. This technique has become more widely available in recent years, and is attractive because it does not involve ionizing radiation. However, although preliminary data have suggested a potential reduction in anxiety, this technique has not been evaluated for ENT RT in anxious/claustrophobic patients who cannot tolerate immobilization masks. Objective: Investigators propose a pilot study to evaluate the feasibility and tolerability of using SGRT to manage position for patients with ENT cancer who report claustrophobia/anxiety. Methodology: 15 participants will be recruited by the treating radiation oncologist from among patients scheduled to undergo radiation therapy at CHUM for their ENT cancer and identifying as claustrophobic/anxious. Participants who consent will be scheduled to undergo their radiotherapy using SGRT. Patients will be systematically treated with Volumetric Modulated Arc Therapy (VMAT) using SGRT on the linear accelerator with the Optical Surface Management System (OSMS) for the duration of the radiotherapy. Measures: Patients' anxiety will be assessed using the GAD-7 and the CLQ throughout the treatment process. The feasibility and accuracy of radiotherapy treatment will be assessed using planning and daily pre-treatment examinations. In addition, skin toxicity will be assessed weekly. Analyses: 1) Descriptive analyses, i.e. frequencies for categorical variables and means and standard deviations for continuous variables. 2) Estimation of confidence intervals. Anticipated outcomes: Completion of this pilot project will enable investigators to plan and refine the methodological and organizational aspects for a large-scale study, i.e., a Phase III clinical trial comparing the use of SGRT with the use of a thermoplastic immobilization mask for anxious patients.
The study was conducted among a group of dental patients aged (6-8 years old) of both genders to assess the following variables in the needleless interparliamentary anesthesia (NUMBEE) compared to traditional local anesthesia: 1. Pain perception. 2. Pain related behaviors. 3. Dental anxiety 4. Anesthetic efficiency. 5. Patient acceptance and preference
Claustrophobia is an irrational fear of restriction and suffocation. It is a specific phobia, according to DSM 5. Claustrophobic patients may fear that restriction of their limbs will hinder their ability to move quickly towards safety. MRI may trigger claustrophobia, because this diagnostic procedure involves a patient laying in a narrow tube. Premedication before MRI scan may occasionally reduce claustrophobia. Prospective observational crossover study of claustrophobic patients who are undergoing MRI scan. At alternate MRI scan sessions, each patient receives rotational premedication using Lorazepam 1mg; or Clonidine tablet 0.2mg; or combined Clonidine 0.2mg + Lorazepam 1mg. Patient will use Claustrophobia Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. CLQ is a patient-administered tool used to assess claustrophobia. In addition, patient will use General Anxiety Disorder Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. GAD-7 is a patient-administered tool that is used to assess anxiety.
The purpose of this study is to examine the effectiveness of virtual reality (VR) delivered exposure therapy for youth with phobias or social anxiety, with and without autism spectrum disorder. The study team is also interested in collecting information to better understand phobias and social anxiety.
Self-efficacy (SE) enhancement after virtual reality exposure (VRET) for heights can promote treatment-induced effects (Raeder et al. 2019). Raeder et al (2019) employed an intervention to enhance SE by introducing specific questions about autobiographical events of success and mastery experiences in the course of VRET. Building on these previous findings, the present study aims to examine whether SE-enhancement DURING and/or AFTER a brief VR-based exposure for fear of heights (in the following referred to as VR-height-exposure) is suitable to promote exposure-induced reductions in height-related fear and avoidance. To this end, repeated visual feedback DURING a brief VR-height-exposure will be used to selectively promote SE and mastery experiences. In a similar vein, SE-enhancement AFTER VR-height-exposure will be administered. The effects of these interventions will be assessed on different treatment outcome levels. It will be further examined whether the combined SE enhancement (DURING and AFTER exposure) is more effective that 1.) SE enhancement performed DURING VR-height-exposure only or 2.) SE enhancement performed AFTER VR-height-exposure only. The investigators hypothesize that SE enhancement (either administered DURING or AFTER VR-height-exposure) will be more effective (as indicated by more pronounced reductions in height-related fear and avoidance) than VR-height-exposure alone. It is further expected that the combined SE enhancement DURING and AFTER VR-height-exposure will be more effective compared to SE enhancement DURING VR-height-exposure alone and/or SE enhancement DURING VR-height-exposure alone.
The goal of this interventional pilot study is to gain experiences in using the Back 2 School (B2S) program for youth with school attendance problems in Norwegian community school- and health services. The main questions it aims to answer are: • What is the feasibility of the Back 2 School program when implemented in Norwegian community school- and health services? • What are the changes in school attendance rates, measures of psychological difficulties, and school related self-efficacy following the intervention? • How do participants experience the B2S program? 16 youth (6-16 years) with school attendance problems, their caregivers and the school participate in the B2S program provided by an interdisciplinary team during the school term of 2022-2023. Researchers will compare school attendance rates before entrance to the B2S program, at termination of the program and at 3-month follow-up. Also, researchers will compare reports on psychological difficulties, quality of life, and school related-self efficacy at baseline and after the intervention. Researchers investigate participants experiences with the program through qualitative interviews with youths, caregivers, teachers and service providers. The researchers further aim to prepare and establish resources and infrastructure for a large intervention study, and to establish a well-functioning cooperation between researchers, research organizations, and municipalities in different regions.
The purpose of this study is to determine whether multi-family therapy is effective in the treatment of school refusal with anxiety in adolescence.
Background: Claustrophobia is the most common type of specific phobia, and in the context of performing an MRI, it leads to premature completion of the test or a sedation. According to some authors, 1,6% of the patients terminated the test prematurely due to claustrophobia, and, in addition, 3.8% underwent conscious sedation. These procedures increase the risk of complications, and the cost of care. The use of anxiolytics is an option to reduce anxiety, but these drugs carry the possibility of suffering adverse effects, and the fact that patients cannot drive home when the MRI is finished. For these reasons, it is especially relevant to determine which non-pharmacological interventions are most effective, and among them, the use of Immersive Entertainment Glasses is a low-interventionist option that can help to overcome fear of the test. Objective: To determine the effectiveness of Immersive Entertainment Glasses in the success of the performance of an MRI and in the reduction of anxiety levels, in patients who express having claustrophobia. Methodology: Design: Clinical trial with intervention and control group. Participants: patients who define themselves as claustrophobic and should have an MRI. The sample will be made up of 206 individuals, divided between an intervention group and a control group. expecting a 20% difference between the success of the test of the control and intervention group subjects. People who meet the inclusion criteria will be distributed into the control or intervention group. The intervention group will use the Immersive Entertainment Glasses to perform the MRI and the control group will have the support of the nurse through educational techniques. Expected results: the success rate in performing MRIs is expected to increase by 20%, thanks to the use of Immersive Entertainment Glasses. Expected duration: 12 months, or until obtaining the expected sample.
Exposure is considered the therapy of choice for specific phobias (SPs). Nevertheless, therapy engagement is extremely limited. SPs are maintained through avoidance of feared stimuli and as such willingness to approach what is feared constitutes a key factor that could explain limited treatment engagement. Values interventions, a key element of acceptance and commitment therapy (ACT), might be one way to increase engagement, yet to this date limited research exists in this area. For the purposes of the current study, two brief values interventions were developed: (a) a personal and (b) a prosocial one. These will be compared to (c) a no-instructions control in increasing willingness to approach and approach behaviour towards phobic stimuli. Ninety participants with flying phobia will be randomly allocated to one of the three groups. To measure willingness to engage with feared stimuli and approach behaviour two behavioural approach tasks using novel technologies (virtual reality), which aimed to expose participants to situations analogous to real life, were developed. Willingness and behavioural approach towards airplanes at a one month follow up will also be assessed. Therefore, it is hypothesised that: 1. Participants in either of the two values intervention groups will have greater willingness to engage and approach behaviour towards feared stimuli compared to those in control, during the study tasks. 2. Participants in either of the two values intervention groups will have greater willingness to engage and approach behaviour towards feared stimuli compared to those in control at follow up. Additionally, as prosocial values provide an evolutionary advantage, the second study aim was to identify if they lead to greater engagement with phobic stimuli compared to personal ones. Therefore, it was also hypothesised that: 3. Participants in the prosocial values group will have greater willingness to engage and approach behaviour towards feared stimuli compared to those in personal values group, both during the study tasks and at follow up. 4. Participants in the prosocial values group will have greater willingness to engage and approach behaviour towards feared stimuli compared to those in personal values group at follow up.
