JomCare Study - A Harm Reduction Study

Chemsex, the use of psychoactive drugs before or during sexual activity, is a growing public health concern associated with striking increases in HIV, particularly among men who have sex with men (MSM). This study proposes to optimize an app-based just-in-time adaptive intervention, called JomCare, which aims to reduce chemsex risk by delivering tailored support when a person is most likely to be vulnerable to chemsex risk behaviors and receptive to intervention, with the purpose of reducing risk and averting new HIV infections.

LIFUS For Neurological Disorders

Low intensity focused ultrasound (LIFUS) has the potential to be used as a means of non-invasive neuro-modulation. To this day, the use of LIFUS is under investigation. Studies in healthy subjects have shown that application of LIFUS to the motor region of the brain can mildly decrease neuron excitability in healthy controls. The purpose of the present study is to evaluate the effects of LIFUS on brain tissue excitability in patients with movement disorders in order to elucidate the therapeutic potential of LIFUS.

Assessments of Obsessive-compulsive Symptoms in Patients With Substances Use Disorder

This observational, cross-sectional case-control study evaluates obsessive-compulsive symptoms among adults with substance use disorder compared with a demographically similar control group without substance use disorder. Patients aged 18-50 years attending the addiction management inpatient and outpatient services at Assiut University Hospital, and healthy controls recruited from relatives, friends, and hospital staff, will complete structured clinical interviews, the Yale-Brown Obsessive-Compulsive Scale, and other standardized scales for psychiatric symptoms, cognition, and quality of life. The main objective is to estimate the prevalence and severity of obsessive-compulsive symptoms in substance use disorder and examine their associations with sociodemographic and clinical factors, addiction severity, and quality of life in the recovery stage.

Machine Learning Technology in Predicting Relapse and Implementing Peer Recovery Intervention Before Drug Use Occurs

The goal of this clinical trial is to study the relationship between substance cravings, cognitive performance, behaviors, and physiological markers in individuals with substance use disorder, as well as the effects of peer recovery intervention in response to abnormal biomarker data detected by wearable technology (e.g., Oura ring, smart watch) and participant responses to questionnaires and cognitive tasks completed on the RNI Health application.

Examining Clinical Research Participation for Substance Abuse Disorder Patient

Clinical study participation percentages haven't always been fully representative of a given demographic. The goal is to find out which aspects of a clinical trial may make it more difficult for patients to take part or see it through. The data will be evaluated through different demographic lenses and identify trends that could help improve the experience of future substance abuse disorder patients during clinical trials.
