Filter by:Aims: To characterize the pattern of cannabis and tobacco use and withdrawal symptoms in people who start treatment for cannabis use disorders (exclusive cannabis, concurrent and/or simultaneous with various tobacco products) through an aplication game and considering the type of users. Methodology: Mixed-methods research composed of three studies. Study I: qualitative participatory action study aimed at exploring the experiences and preferences of the cannabis users on the use of apps. This information will be instrumental in the co-design of the app. Study II: prospective longitudinal study aimed to establish consumption patterns and transitions between substances and to validate the scale of cannabis withdrawal symptoms in the Spanish population. Sample size: expected RR=1.20, α =0.05, β= 0.20, losses= 20% (n=282). Study III: qualitative study to explore participants' experiences during the process of quitting cannabis and / or tobacco. Expected results: Characterization and prediction of variables that influence cannabis and tobacco cessation/ reduction and describe withdrawal symptoms according to consumption patterns with aim of improving the design of future interventions.
Suicide is the 10th leading cause of death for Americans of all ages and more people in the United States now die from suicide than die from car accidents. Although death by firearm remains the most common cause of suicide in the United States, an intentional overdose of substance usage such as prescription opioids accounts for over 5,000 suicides per year. In 2017, more than 70,000 drug overdose deaths occurred, making it the leading cause of injury-related death, and well over half (67.8%) involved opioids. The dramatic increase in opioid overdose raises concerns about their contribution to suicidal outcomes (e.g., suicidal behavior, ideation, and attempts). Abuse of prescription opioids is characterized by the persistence of opioid use despite negative consequences. The neurobiology of opioid abuse involves the mesolimbic dopamine systems as the main neural substrate for opioid reward, and altered dopamine release in this system plays a role in opioid abuse. Moreover, the cortico-striatal system, especially the orbitofrontal cortex (OFC), has been associated with the abuse of many substances, including opioids and alcohol. Structural brain alterations in frontal areas, particularly the OFC, may cause executive control dysfunctions of mood which are highly associated with suicidal ideation. Recent preclinical work has shown that higher input from the OFC to the dorsal striatum (dSTR) is associated with compulsive reward-seeking behavior despite negative effects (e.g., punishment). In this study, the investigators propose that OFC/dSTR connectivity may be one neural differentiator that distinguishes between those who become compulsive users after initial opioid use and those that do not. Moreover, suicidal patients among those who become compulsive users may have higher OFC/dSTR connectivity compared to non-suicidal patients.
Impaired cognitive function is common among patients with substance use disorder (SUD). This is particularly related to executive functions (EF), which includes abilities like decision-making, consequence analysis and impulse/self-control. EF is recognized as an important determinant of treatment outcome as it is associated with dropout rate, attendance to therapy sessions and absence of relapse following treatment termination. Exercise seem to improve cognitive/executive functions, particularly in individuals with cognitive impairments. Aerobic exercise also affects signaling substances and growth factors known to inhibit neural degeneration, and improves cerebral insulin sensitivity and blood flow, contributing to improved brain function. There is a lack of knowledge regarding how to improve EF in SUD patients, and whether such improvements can benefit other parts of the treatment, such as psychotherapy. Aerobic exercise is a well-recognized and cost-effective intervention for cardiovascular and metabolic health, with promising effects on cognitive/executive functions. A randomized controlled trial will be carried out to investigate the effects of aerobic exercise on EF, molecular markers of neuroplasticity and brain function, and treatment outcome in SUD patients. The investigators expect to achieve new knowledge regarding cognitive impairment among SUD patients and to what extent aerobic exercise can improve cognitive abilities and treatment outcome.
This is a 5-year Hybrid Type 1 Effectiveness-Implementation Randomized Control Trial (RCT) that compares two models of linking and retaining individuals recently released from justice involvement to the continuum of community-based HIV prevention and treatment, HCV treatment, STI treatment, and opioid use disorder (OUD) prevention and treatment, medication for opioid use disorder (MOUD) service cascades of care.
The purpose of this proof-of-concept study is to evaluate the safety, feasibility and acceptability of a breathwork workshop intervention in individuals with cannabis use disorder.
To test the efficacy of Project ALERT with the support enhancement tool, Getting To Outcomes.
This cohort study is a large population-based study in the UK to determine the risks of comorbid mental health conditions (including depression, anxiety and other potential psychological complications of vitiligo) in adults with vitiligo compared to controls and to evaluate whether the relative risks may vary by different ethnicity.
The Coalition on Psychiatric Emergencies (CPE) stressed in 2016 that emergency providers were increasingly recognizing the important role of the Emergency Department (ED) in reducing adverse outcomes associated with untreated with substance abuse liaison department (SUDs). Additional research is required to close identified knowledge gaps and improve care of ED patients with SUD. Of the more than 4.5 million ED visits in 2009 in US for drug-related causes,34-32% involved alcohol use alone or in combination with other drugs. Few studies investigated the clinical characteristics of patients referred to an addiction liaison department in a general hospital. The present study will be retrospective in a sample of 700 patients consecutively admitted for addictive behaviors in the emergency department and in the Medicine or Surgery departments of the Amiens University Hospital Center, France.
In this study investigators are examining the feasibility and acceptability of an expanded and technology-assisted aftercare program with persons released from a crisis stabilization unit (CSU) who were brought to the CSU by choice of law enforcement. Investigators are assessing the critical elements of CSUs, examining the feasibility and acceptability of pairing mobile and technology-assisted aftercare to improve treatment access and retention; and developing a study protocol to be used in a future multisite randomized controlled trial (RCT). Crisis stabilization units provide law enforcement officers an alternative to jail for individuals experiencing a substance use or mental health disorder crisis contributing to criminalized behavior. This study is designed to assist with the diversion of individuals toward treatment and away from subsequent contact with law enforcement through piloting mobile and technology assisted aftercare services to persons released from a CSU. One of the largest barriers to the effectiveness of CSUs is retaining the individual in treatment after discharge. Logistical factors including transportation, stable housing, and long waitlists for community-based treatment decrease treatment access. These factors may also be complicated by an individual's understanding of the importance of remaining in treatment as well as their motivation to continue. To overcome these barriers and enhance the impact of CSUs, investigators are developing an expanded model which includes mobile and technology-assisted modalities that address psychological, behavioral, and medication-assisted treatment.
Sport is a privileged area to promote socialization and health values, such as companionship; a healthy lifestyle; cooperation to achieve common goals, and justice, rejecting unjustified advantages in competition. The concept of fair play is on which the development of those values pivots. From a holistic perspective, it is possible to define fair play, not only as a way to participate but also as a way of projecting people in life with values, assuming a set of behaviors that enhance a healthy and respectful sporting experience with opponents, the companions, the spectators, the referees and all the agents that take part in the sport practice.
