Filter by:Transrectal prostate biopsy is a commonly performed ambulatory procedure for diagnosing prostate cancer. Prostate biopsy are associated with pain or anxiety. Nitrous oxide (or laughing gas) is a well-known inhaled anesthetic which is frequently used in dental offices and for pediatric procedures to alleviate a patient's anxiety and pain. This study seeks to determine whether administration of nitrous oxide at the time of prostate biopsy will improve a patient's experience of care.
Over 50% of patients with major depressive disorder (MDD) do not respond to initial treatment and relapse is common. In particular, comorbid depression and anxiety disorders are associated with more treatment resistance. Thus, there is a great need for novel, more targeted treatments. Transcranial direct current stimulation (tDCS) is a novel intervention that can be used to causally target neural excitability and plasticity in brain regions/circuits implicated in regulating mood and anxiety and emerging evidence suggests that it reduces threat sensitivity. Here the investigators propose to use tDCS to target threat sensitivity as a core symptom of anxious depression to determine if the investigators can engage the neural circuits that are treatment targets. Following the administration of a single dose of anxiolytic or antidepressant treatment, early changes in emotional processing have been observed in healthy people and clinical groups. Among patients, acute cognitive effects - such as a reduction in threat sensitivity - have been shown to predict response to drug and behavioral treatments. Functional magnetic resonance imaging (fMRI) studies have confirmed hyperactive amygdala and/or hypoactive prefrontal activity in patients, indicating an imbalance of activity within this cortico-limbic circuit that sub-serves threat identification (amygdala) and top-down control (prefrontal). Specifically, treatments aiming to remediate prefrontal/ amygdala dysfunction could be a critical target in patients exhibiting these deficits. Several clinical trials have shown that administration of frontal cortex tDCS is a potentially effective treatment for MDD. However, underlying mechanisms of action are unclear. To meet this gap, the investigators propose an experimental medicine study (target identification and initial target engagement paths) where 141 volunteers with anxious MDD will be randomized to receive a single session of active or sham tDCS in a parallel design. Threat sensitivity will be measured using task and resting state fMRI and potentiated startle electrophysiology. Preliminary data suggest reductions in behavioral threat sensitivity from a single session of frontal tDCS. This was followed up with an fMRI study which found that a single session of active vs sham frontal tDCS reduced amygdala response to fearful faces whilst simultaneously increasing frontal attentional control signals. This provides evidence that modulating activity in the frontal cortex inhibits amygdala response to threat, highlighting a potential neural mechanism for the behavioral reduction in threat sensitivity. In addition, this offers initial mechanistic insights into the efficacy of tDCS in clinical trials for the treatment of MDD and anxiety disorders, suggesting that threat sensitivity may be a suitable cognitive target. The current proposal builds on this to establish acute effects of frontal tDCS on amygdala response to threat (primary aim), frontoparietal response to threat (secondary aim), startle response under threat (secondary aim) and approach-avoidance-conflict (exploratory aim). The ultimate aim is to apply these multi-level acute findings to mechanistic clinical trials of tDCS, to test their prediction of treatment response (full model path) and improve patient outcomes.
A randomized control trial examining the feasibility, acceptability, and preliminary efficacy of providing access to the MindShift CBT mobile app via tablet for acute psychiatric inpatients.
This study is a randomized control study to determine the impact of a tailored, web-based mindfulness program to reduce anxiety and increase the quality of life in older adults experiencing dementia-related fears, relative to a conventional meditation program.
80 participants studying in the physiotherapy technician department were included in this cross-sectional study. Participants' age, gender, year of being a student, the people they live with, the precautions they take regarding COVID-19, whether there is a history of COVID-19 in them or their immediate surroundings, and whether they have COVID-19 transmission and / or contagion fears during their vocational training, whether there are fears of achieving professional goals and competence because of COVID-19 and / or its consequences were recorded. Afterwards, the participants were asked to answer the questions on the coronavirus anxiety scale, the fear of COVID-19 scale and the cognitive and behavioral avoidance subscales of the Avoidance Attitudes from COVID-19 scale.
This study was conducted with a randomized controlled experimental design to determine the effect of virtual reality headset on children's fear and anxiety during vaccinations. Research Hypotheses: Hypothesis 0a (H0a): There is no difference in fear scores between the experimental group in which virtual reality glasses were used during vaccination administration and the control group. Hypothesis 1a (H1a): There is a difference in fear scores between the experimental group in which virtual reality glasses were used during vaccination administration and the control group. Hypothesis 0b (H0b): There is no difference in anxiety scores between the experimental group in which virtual reality glasses were used during vaccination administration and the control group. Hypothesis 1b (H1b): There is a difference in anxiety scores experienced between the experimental group in which virtual reality glasses were used during vaccination administration and the control group.
A pandemic that originated in the Wuhan region of China in December 2019 was detected as a new type of coronavirus disease called coronavirus 2019 (COVID-19). In the first phase of the outbreak, specialists explained ways to maintain physical health . However, pediatric surgical procedures and anesthesia applications continued during this period. Surgery in pediatric patients is an unpleasant and potentially 'threatening' experience, often followed by preoperative anxiety due to the child's illness, hospitalization, fear of anesthesia - especially the time of anesthesia induction - and the surgery itself . Anesthesia is a stressful procedure for the child and the entire family. Both the COVID-19 pandemic and the surgical procedure are reflected in the symptoms of anxiety, fear or acute stress disorder for children and their families. As the disease spread, investigators started to emphasize the importance of protecting mental health. Identifying factors that contribute to significant preoperative anxiety levels in pediatric patients and their parents can help healthcare professionals choose the most appropriate from a variety of alternative strategies for anxiety control. This study was planned to evaluate the COVID-19 anxiety and phobia levels of the parents of pediatric patients are scheduled to undergo surgery under general anesthesia in Turkey.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has begun, first in Wuhan, China, and then became a pandemic. The first SARS-CoV-2 case in Turkey was reported on March 11, 2020. People older than 65 years old became subject to lock down measures beginning on March 21, while people younger than 20 years old became subject to lock down measures beginning on April 03. A total lock down has been implemented a few times lasting between 3 to 4 days, especially at weekends. Several studies show that mental health problems could occur in public during the SARS-CoV-2 pandemic. Depression and anxiety are a commonly known mental health issue in post-stroke patients. This patient population, who usually have to spend most of their time at home, remained completely at home and socially isolated due to the precautions required by the pandemic. Based on the above research evidence; depression, anxiety and phobia of SARS-CoV-2 may increase in the post stroke patients due to being in risk group and effects of measures taken against SARS-CoV-2 pandemic. Therefore, we aimed to assess the depression, anxiety and SARS-CoV-2 phobia in post stroke patients during SARS-CoV-2 outbreak, and to explore the potential influence factors.
To date, there have been no studies done relating serum cortisol levels and intranasal dexmedetomidine sedation. However, there was a behavioral study done on pediatric patients confirming reduction serum cortisol levels with perioperative dialogue intervention.There have been a number of studies done on adult patients indicating that dexmedetomidine was indeed capable of reducing level of anxiety with evidence of lower serum cortisol levels. Hence, we postulated that intranasal dexmedetomidine administration in pediatric patients will lower the serum cortisol levels but we need to evaluate the extent of reduction.
The term "outpatient" refers to all the medical, organizational and administrative care that allows the patient to leave the same day the structure where the ambulatory procedure was performed. The usual rule for patients undergoing endoscopic surgery or surgery under general anesthesia is to transport them to the endoscopy or operating room lying on a stretcher, even if they can walk independently. In recent years, the procedure of bringing the patient standing in the operating room seems to have many advantages. It is readily accepted by patients and may even lessen their anxiety. Nevertheless, reluctance and fears are sometimes expressed by patients who do not know this new procedure. Our team has introduced this procedure for patients admitted to the ambulatory hospitalization sector and to join the endoscopy sector. The aim of our work is therefore to objectify the fears expressed by patients who have to go to the endoscopy room before general anesthesia and to evaluate their progress after endoscopy
