Filter by:This is a randomized controlled trial. The aim of the study is to the effects of Virtual Reality and Local Cold-Vibration applications in reducing anxiety, fear and pain due to intravenous catheterization (PIC) in children aged 5-10 years. PIC was found to be effective in reducing anxiety, fear and pain due to peripheral intravenous catheterization.
A randomized controlled trial is conducted to evaluation of the effects of virtual reality and local cold-vibration applications in reducing anxiety, fear and pain due to intramuscular (IM) injection in children aged 5-10 years. It has been determined that the use of Virtual Reality and local cold-vibration are effective interventions in reducing anxiety, fear and pain due to IM injection in children aged 5-10 years.
Fear of cancer recurrence (FCR) is a highly prevalent, disruptive, and under-treated problem for breast cancer survivors. This randomized controlled trial will test the efficacy of group-based Acceptance and Commitment Therapy compared to Cognitive Behavioral Therapy and enhanced usual care for breast cancer survivors suffering from FCR while examining its cost-effectiveness and the mechanisms by which the intervention may work. Study findings will guide the future care of breast cancer survivors with FCR.
Cannabidiol (CBD) is a phytocannabinoid that is one of 113 identified cannabinoids in the cannabis plant. It is derived from the hemp plant, and may treat conditions like pain, insomnia, and anxiety. CBD is a critical component of medical marijuana and does not cause the "high" typically associated with cannabis. According to the World Health Organization, CBD has shown no evidence of abuse or dependence potential. However, to the investigator's knowledge, there have not been many acute clinical studies to characterize the effects of CBD in the brain. Despite the rapid influx in CBD readily available to the public, very little is known about such effects. Some studies have shown alterations in resting state connectivity, while others have described changes in specific regions of the brain, or in networks associated with various cognitive functions. For example, CBD has been shown to increase fronto-striatal connectivity and reduce mediotemporal-prefrontal connectivity, suggesting that CBD may affect brain regions involved in salience processing. Unfortunately, few studies have examined CBD in isolation. Additionally, several studies have suggested that CBD may have a neuroprotective effect when it comes to individuals at high risk for psychiatric conditions. In this study, the investigators propose an acute administration, double-blind, placebo-controlled study in which 100% THC-free CBD will be compared to placebo (https://foliumbiosciences.com/). To the investigator's knowledge, the acute effects of this specific product have not been tested. Specifically, the investigators will examine: 1) the neurometabolic and neurophysiological effects of CBD compared to placebo and 2) the behavioral effects of CBD on measures of working memory and response inhibition. Participants will be recruited to take encapsulated, THC-free CBD provided by Folium Biosciences, in which they will have a pre- and post-ingestion scan. Each participant will have a 72-hour washout period after which they will be asked to come back for a placebo scan (however, the order will be counterbalanced so that equal numbers of participants will receive placebo/supplement and supplement/placebo). Individuals will be randomized into the supplementation group, as well as the order.
Given the overall lack of treatment adherence/efficacy, side effects of drugs, and the substantial burden of anxiety disorders on the individual and on the national healthcare system, there is a critical need for mechanistic research into the CNS mechanisms that underlie these disorders. Accordingly, the objective of this grant is to use noninvasive neuromodulation to causally identify the key neural mechanisms that mediate the cognitive symptoms of anxiety. This project is relevant to public health because it has the potential to lead to novel repetitive transcranial magnetic stimulation treatments for pathological anxiety.
To determine the effects of SRX246 on fear and anxiety based on fear-potentiated startle in humans. Additionally, the effects of the compound on emotion recognition will be explored.
