Oxytocin and Brain Reward and Stress Responses to Infant Cues in Addicted Mothers
A prior study by the principal investigator of this project identified dopamine- and oxytocin-related brain pathways that showed a diminished response when addicted mothers viewed the faces of their own vs. unknown infants, compared with non-addicted mothers. These areas include the hypothalamus, striatum and ventromedial prefrontal cortex. In addition, the investigators plan to examine activation patterns within the salience network, which includes the anterior cingulate cortex and the anterior insula. Oxytocin, a neuropeptide with decreased blood levels seen in addicted mothers, is integrally involved in maternal brain and behavioral responses. When administered intranasally, the pilot data has shown enhanced activation of the striatum, prefrontal cortex (PFC) and amygdala. The purpose of this study is to continue and expand upon the previous investigation of maternal addiction, by conducting a randomized, double-blinded, placebo controlled, crossover study of intranasal oxytocin on maternal brain responses. 150 mothers from the University of Iowa and the Yale Child Study Center will be enrolled (75 with a history of drug addiction and 75 matched control mothers), along with their 2 to 12-month-old infants, to participate in four study visits over a two-month period.

Effect of Recent Alcohol, Smoking and Psychotropic Drug Use on Delirium in ICU
Investigators are seeking to determine the impact of recent alcohol, smoking or psychotropic drug use prior to intensive care unit (ICU) admission on incidence of delirium and sedation requirements. Study design: A prospective observational study, in a medical ICU of a tertiary university hospital. Methods: For all new ICU admissions, a 1-page questionnaire including Alcohol Use Disorders Identification Test (AUDIT-C), smoking history and prior medication use was given to the patient or closest family members. Delirium was assessed by trained ICU nurses using Intensive Care Delirium Screening Checklist and Richmond Agitation-Sedation Scale.

Alcohol Addiction: A Systems-oriented Approach; Functional Validation II: Neuroimaging x Genetics
The goal of the multicenter subproject (SP) 10 of the eMED Alcohol Addiction Consortium - A Systems-Oriented Approach is to study neuroimaging x genetics predictions in an existing sample (NGFNplus) of tightly endophenotyped and genome-wide genotyped alcohol dependent subjects (N=240) and controls (N=240); (ii) to translate the results of neuroimaging and genetic analyses from an adolescent risk sample (IMAGEN) to adult disease (NGFNplus sample) by examining related MRI-paradigms tagging the same functional brain systems in both samples (e.g. reward system, inhibitory control system, emotion processing, working memory); (iii) to conduct a follow-up neuroimaging study on the NGFNplus sample validating the neurobehavioral risk profiles predictive for juvenile harmful alcohol use in adult patients with alcohol addiction, (iv) to expand the NGFNplus sample by including a new set of healthy subjects with high genetic risk (1st degree relatives of patients with alcohol addiction). The investigators will do so by using elaborate imaging genetic methods that are already available and successfully used in other multicenter studies by the investigator's research group (e.g. univariate analyses, functional and effective connectivity analyses, polygenetic scores, network topology) as well as by using complex computational algorithms and mathematical models, in particular advanced machine learning methods, developed in SP 6. The investigator's approach aims in the long to predict and characterize longitudinal outcomes in patients with alcohol addiction (5 years following our index session) and to complement the NGFN-sample with an add-on study with 1st degree relatives that will allow the investigators to test the generalizability of the identified predictive risk profiles for early risk identification.

Working With HIV Clinics to Adopt Addiction Treatments Using Implementation Facilitation (WHAT-IF?)
Tobacco, alcohol and opioid use disorders threaten the health of HIV-infected patients. What if evidence-based counseling and medication treatments for tobacco, alcohol and opioid use disorders (herein refered to as addiction treatments) were routinely provided in HIV clinics? Implementation Facilitation is an established strategy to increase the uptake of evidence-based treatments. Our goal is to evaluate the impact of Implementation Facilitation on the use of addiction treatments in four large HIV clinics. The purpose of the WHAT-IF study is: Aim 1. Among key stakeholders, to use quantitative and qualitative (mixed) methods to identify the site-specific evidence, context and facilitation-related barriers and facilitators to the integration of addiction treatments to help tailor an Implementation Facilitation for each clinic. Aim 2. To evaluate the impact of Implementation Facilitation on: 2a: Organizational readiness to deliver addiction treatments 2b: Provider readiness to deliver addiction treatments 2c: Provision of addiction treatments 2d: Changes in organizational models of care used to deliver addiction treatments Aim 3. To evaluate the impact of Implementation Facilitation on antiretroviral therapy receipt, HIV viral suppression, VACS Index, and retention in HIV care among patients eligible for addiction treatment.

A Pilot Study of Deep Brain Stimulation of the Sub-thalamic Nucleus to Treat Treatment-resistant Cocaine Addiction With Severe Somatic or Psychiatric Complications
Cocaine addiction is a chronic condition with severe cardiac, neurologic, psychiatric and social complications. Cocaine is the second most consumed illicit drug in France. Its prevalence has been multiplied by 3 between 2000 and 2008, and is still on the rise. Craving, the compulsive need to consume, is a key feature of cocaine addiction. It is also predictive of treatment efficacy. However, there is no validated treatment for severe cocaine dependence yet. Response to current psychological and medical treatment is poor, with 73% relapse after 3 months. Patients with severe cocaine addiction are thus in a therapeutic deadlock. To address these unmet medical needs, the investigators designed a pilot study (n=2) to evaluate the safety and the efficacy of the deep brain stimulation of the subthalamic nuclei (STN-DBS) in severe cocaine addiction with at least one cardiac, neurologic or psychiatric complication. Indeed, compulsivity is a critical component of craving, and severe treatment-resistant obsessive compulsive disorder (OCD) are already successfully treated using STN-DBS. Moreover, animal studies recently demonstrated a therapeutic effect of STN-DBS in rats addicted to cocaine. Together, these two lines of research suggest a therapeutic effect of STN-DBS in cocaine addiction mediated by an anti-obsessive mechanism on craving.

Genetic Markers in Sexual Addiction
The study is intended to identify gene polymorphisms significantly associated with specific behavioral- and preoccupation-typologies of sexual addiction, and to identify additional potential genetic markers of sexual addiction. Research subjects with sexual addiction will be identified from the out-patient and in-patient populations of the investigative sites. Research subjects in the Control Group will be identified from the general population and from the student body of selected colleges. Approximately 1100 subjects will be enrolled in the study. Anticipating 10% drop-out, this is intended to generate a population of approximately 500 men and women clinically diagnosed with sexual addiction, and approximately 500 healthy men and women who do not meet diagnostic criteria for sexual addiction nor have psychopathology who will serve as the control population.

Integrated Collaborative Care Teams to Enhance Service Delivery to Youth With Mental Health and Substance Use Challenges: Protocol for a Pragmatic Randomized-controlled Trial
Among youth, the prevalence of mental health and addiction (MHA) disorders is roughly 20%, yet youth are challenged to access services in a timely fashion. To address MHA system gaps, this study will test the benefits of an Integrated Collaborative Care Team (ICCT) model for at-risk youth with MHA challenges. In partnership with community agencies, adolescent psychiatry hospital departments, and family health teams, investigators have developed an innovative model of service provision involving rapid access to MHA services. This model will be implemented and compared to the usual treatment youth receive in hospital-based, outpatient, mental health clinics in Toronto. A rapid, systematic, approach to MHA services geared to need in a youth-friendly environment is expected to result in better MHA outcomes for youth. Moreover, the ICCT approach is expected to decrease service wait-times, be more youth- and family-centred, and be more cost-effective.
