Filter by:Chronic drug addiction is not only associated with increased mental health symptoms, such as anxiety and depression, but also with brain (neural and cognitive) deficits. These neurocognitive deficits (NCDs) in memory, attention, decision-making, self-control and judgement disturb normal daily functioning and attempts for abstinence. These NCDs are also associated with worse long-term treatment outcomes. Current treatment programs for addiction to opioids and amphetamines are mainly focused on abstinence from illicit drugs with or without assistance of medications, with the assumption that these NCDs will subsequently heal. However, NCDs are found to persist even after a long-term abstinence and are thought to contribute to relapse, decreases quality of life, or lack of reintegration into society. Furthermore, NCDs (particularly related to attention and memory) are considered a potential obstacle for engagement in therapy services for addiction and associated mood, anxiety and trauma-related comorbidities (i.e., cognitive-behavioral therapies). Brain rehabilitation programs focused on compensatory strategies and training exercises for NCDs associated with traumatic brain injuries, stroke, multiple sclerosis and schizophrenia has consistently been found to improve functioning and long-term outcomes for these populations. There have been a few preliminary attempts to transplant cognitive rehabilitation with substance use populations, with some limited promise. However, these previous studies failed to link cognitive strategies with the drug use and affective/craving symptoms experienced by patients and also did not fully incorporate knowledge gained from neuroscientific research on opioid and/or methamphetamine addiction specifically. The aim of this study is to characterize clinical efficacy for an intervention targeting NCDs in opioid and/or methamphetamine addiction by enhancing awareness and use of neurocognitive skills in the context of substance use recovery. This aim will be accomplished by randomizing 80 subjects with opioid and/or methamphetamine use disorder who are already enrolled in substance use treatment in the state of Oklahoma to also complete a novel "Neurocognitive Empowerment for Addiction Treatment" (NEAT) program developed by a group of investigators at Laureate Institute for Brain Research, Tulsa, Oklahoma. NEAT will be novel in (a) its use of cartoons, brain awareness games and real-life scenarios to ensure it is interactive and engaging, (b) the focus on the role of neurocognitive deficits in recovery from substance use and co-occurring mental health symptomatology, and (c) its incorporation of neuroscientific findings specific to substance use to the training and exercise strategies. Subjects will be followed up for twelve months after starting the program with different measures for addiction and mental health recovery to explore the efficacy of NEAT compared to the control intervention. Using LIBR's cutting-edge neuroimaging facilities before and after interventions, this study has the unique opportunity to monitor not only clinical outcomes but also potential changes NEAT may have on brain structure and function. In case of finding reasonable clinical efficacy for NEAT, it will be hopefully integrated as a manualized brain rehabilitation program to the substance use treatment programs.
Postoperative pain continues to be untreated despite the application of multimodal analgesia, medication and new analgesic techniques. Traditional opioid pain treatment has many side effects, while invasive methods, such as epidural catheter, have high costs and difficulties during application. Lidocaine is a local anesthetic and its administration with intravenous routes has analgesic, antihyperalgic and antiinflammatory action. It increases the motility of the intestine and has antiemetic properties. The advantage of this method is the low cost of the preparation and its easy application. The intravenous administration of lidocaine for postoperative analgesia is recently used and not sufficiently researched technique .
The primary objective of this study is to evaluate the impact of treating opioid use disorder (OUD) in pregnant women with extended-release buprenorphine (BUP-XR), compared to sublingual buprenorphine (BUP-SL), on mother and infant outcomes. The primary hypothesis is that the BUP-XR group will not have greater illicit opioid use than the BUP-SL group during pregnancy (non-inferiority).
With the increase of substance abuse over the world, substance abuse e.g. ketamine and methamphetamine related voiding dysfunction is becoming an important medical problem. However, while the clinical manifestation of the condition is becoming better defined, the underlying pathophysiology is still poorly understood. Moreover, majority of the current treatment is just based on the experience on some small case series and there is no treatment data for larger patient sample or standard recommended treatment in the literature. In order to improve the management of this condition, investigators have formulated a treatment protocol based on the current literatures on the management of voiding dysfunction and also a similar condition, interstitial cystitis / painful-bladder syndrome (IC/PBS). The protocol basically consists of the following modalities: - Basic information and education on the condition, principle of treatment and psychosocial support. - First line treatment will include a course of oral anti-inflammatory drugs (for the control of the inflammation process and pain) and anticholinergic agents (for the irritative urinary symptoms). - If these simple oral medication are found to be not effective, then further treatment will include other oral medications, such as amitriptyline and gabapentin, and some drugs that directly applied into the bladder cavity (hyaluronate) or bladder muscle (botulinum toxin). - For those patients with intractable symptoms and failed all the above treatments, surgical treatment (hydrodistension, augmentation cystoplasty) will be discussed. The purpose of this research is to assess the effectiveness of the above treatment protocol in the management of substance induced voiding dysfunction and also assess any possible adverse events related to the usage of the drugs.
This is a sub-study of NIDA CTN Protocol 0080: Medication Treatment for Opioid Use Disorder in Expectant Mothers (MOMs; Unique protocol ID: 2019-0429-1). Caretakers of the infants delivered by MOMs participants will be offered the opportunity to enroll in this sub-study, which is designed to evaluate the impact of extended-release buprenorphine (BUP-XR), relative to sublingual buprenorphine (BUP-SL), on infant neurodevelopment. The additional data collected in this sub-study will be combined with data from the main MOMs trial.
This is a sub-study of NIDA CTN Protocol 0080: Medication Treatment for Opioid Use Disorder in Expectant Mothers (MOMs; Unique protocol ID: 2019-0429-1). Participants in MOMs will be offered the opportunity to enroll in this sub-study, which is designed to evaluate conceptual models of the mechanisms by which extended-release buprenorphine (BUP-XR), may improve mother-infant outcomes, compared to sublingual buprenorphine (BUP-SL). The additional data collected in this sub-study will be combined with data from the main MOMs trial. It is hypothesized that: (1) the buprenorphine blood levels will vary, depending on which formulation of buprenorphine was received, (2) the variation in buprenorphine blood levels will be associated with fetal behavior (including fetal heart rate variability) (3) the variation in buprenorphine blood levels will be associated with differences in mother outcomes (including medication adherence and illicit opioid use) (4) the variation in buprenorphine blood levels and in fetal behavior will be associated with infant outcomes (including neonatal opioid withdrawal syndrome and infant development).
Retrospective analysis to evaluate impact of an in-home addiction treatment program on first responders with substance use disorder.
Opioid use disorder (OUD) is among the costliest and deadliest substance use disorders (SUDs) in the US and world-wide. Opioids were involved in 42,249 deaths in the US in 2016, which were more than deaths due to road accidents and gun violence combined. Opioid overdose deaths were five times higher in 2016 than 1999. Meanwhile, the treatment options for OUD are limited and long-term efficacy is poor. There is a hope that recent advances in understanding of the cognitive neuroscience underlying addictive behavior, like drug craving and its regulatory processes, can bring new opportunities for more effective and personalized treatment options for OUD. Drug craving is the signature aspect of OUD as well as other SUDs which has been associated with continued drug use and relapse. In previous studies, the investigators have shown significant response to drug related cues in both frontoparietal and limbic areas including amygdala and ventral striatum. In a recent pilot study, the investigators showed significant lower connectivity between amygdala and frontoparietal areas, including dorsolateral prefrontal cortex (DLPFC) and inferior parietal cortex (IPC), major nodes of the executive control network (ECN), in patients with OUD compared with healthy controls. The central role of the ECN is to perform top down regulation of subcortical limbic areas during self-control, emotion-regulation, and response- inhibition tasks. These processes are well known to be affected in different psychopathologies including SUDs. There is a growing body of evidence that external frontoparietal synchronization (FPS) with transcranial alternating current stimulation (tACS) can potentially modulate connectivity within ECN and between ECN and limbic areas. This may improve some aspects of executive function and top down regulation. tACS is a low-cost and scalable non-invasive brain stimulation technology without any serious side effects. The procedure involves the transcranial delivery of low levels of alternating current (0.1-2 mAmp) in different frequencies through the skull into the brain with both online and long-term offline effects. This trial is the first combined tACS/fMRI study to examine the acute offline effects of FPS on neural substrates underlying drug induced craving. We hypothesize that FPS amplifies the ECN top-down modulatory role via its connectivity to other cortical-subcortical areas. In this experimental design, the investigators will recruit 60 people with OUD during the early abstinence phase in a residential setting divided into two parallel arms with active and sham FPS tACS. Each subject will undergo resting state and task based (drug cue exposure paradigm) functional MRI pre and post FPS. The investigators will also conduct individual difference analyses to explore the potential predictors for FPS response, including pre-FPS top-down connectivity measures of ECN and other subjective, clinical, behavioral, structural, and functional variables. The results of this study will provide mechanistic neuroscience-based evidence for the efficacy of FPS and will advance the field towards precision addiction medicine.
This study is being done to see if outcomes for both a premature infant's parents and the infant born prematurely who have spent time in the neonatal intensive care unit (NICU) can be improved through parent cognitive behavioral therapy (CBT) sessions.
The purpose of this study is to evaluate the Computerized Exercise to Alter Stimulant Approach Responses (CEASAR), a novel stimulant use cessation intervention, for clients currently enrolled in a treatment centre for mental health and addiction. The investigators plan to conduct a randomized, single-blind controlled trial involving inpatients presenting with concurrent disorders to test the impact of this novel computerized intervention. This pilot study will be conducted at the Burnaby Centre for Mental Health and Addiction (BCMHA) in Burnaby, BC, Canada.
