Filter by:The aims of STRIDE were changed as of July, 2014. The revised project, called STRIDE2, has a longitudinal, non-randomized, observational study design. The population under study consists of individuals living with HIV who are dependent on opioids.
The proposed study will examine the threshold for nicotine self-administration (NSA) using five different nicotine doses in young adult male and female non-dependent smokers (light and intermittent smokers or LITS). We propose a double-blind, placebo-controlled study that will enroll 195 individuals, targeting a total of 72 completers (36 male and 36 females). In each of the five experimental sessions, smokers will be randomly assigned to one of the five doses of nicotine (0.0125, 0.025, 0.05, 0.1 and 0.2 mg/70 kg). The highest dose, 0.2 mg/70 kg, corresponds to nicotine delivered by about one or two puffs of a cigarette. At the beginning of each experimental session, smokers will sample the assigned both the nicotine dose for that experimental session, and the placebo (saline) dose, followed by the opportunity to choose between nicotine and placebo for a total of ten choices over a 150-minute period. The main outcomes will be threshold dose (the minimum dose of nicotine that is self-administered more than placebo) and the slope of dose-response for nicotine self-administration (changes in nicotine self-administration per unit change in nicotine dose). We will also collect measures of nicotine intake (cotinine), nicotine clearance (3-hydroxycotinine (3-HC) / cotinine), and self-report drug effects
Evaluation to determine if auto-induction can be used as a surrogate measure of nicotine receptor up-regulation through an observational study using nicotine replacement therapy for two weeks and no intervention for two weeks.
The purpose of this study is to 1) determine the efficacy of manualized Short-term Treatment of Internet and Computer game Addiction (STICA), assess 2) the durability of treatment response in these patients and 3) the impact on associated psychiatric symptoms, e.g. social anxiety and depression.
1. Obesity is a big health problem worldwide. 2. Mostly obese people have food addiction and bad eating habits. 3. Bariatric surgery is a good alternative for patients who failed to loose weight with other measures like behavioral changes, activities and sports, diet, etc.. 4. The investigators know the changes occurred after surgery in eating habits due to restrictive and malabsorptive feature of the surgery performed. 5. There is no study in the literature to measure these changes. 6. The investigators will try to detect these kind of behavioral changes by a survey before and after surgery.
The purpose of this study is to determine whether essential polyunsaturated acids (omega 3) are capable of reducing chocolate craving symptoms in healthy patients. Our hypothesis is that the omega 3 fatty acids have properties which stabilize and normalize neuronal functioning in many conditions, including chocolate craving.
This project will modify Community Reinforcement and Family Training (CRAFT; n=15) and Alanon/Naranon Facilitation (ANF; n=15) for use with parents who are concerned about an out-of-treatment adolescent. ANF was selected as a comparison because Alanon and Naranon are the most commonly available method for helping family members. The investigators will compare CRAFT for parents (CRAFT-P) (n=77) and ANF (n=77) to determine if there is a significant difference in adolescent treatment entry. Parents will attend a maximum of 18 sessions with a family specialist and also complete questionnaires periodically over a 12-month period. Parents' adolescents will have the opportunity to participate in the study by completing questionnaires at the same time points as their parent. Our primary hypothesis asks whether participants who are enrolled in the CRAFT-P condition will report more adolescent treatment entry than the ANF condition. Our secondary hypotheses examine: 1) reductions in adolescent substance use and behavior problems in the CRAFT-P group compared to the ANF condition, 2) improvements in parenting skills in the CRAFT-P group compared to the ANF condition and 3) significant pre to post treatment effects for improvements in social functioning, mood, and in parent-adolescent relationship satisfaction.
The use of crack-cocaine is growing at alarming rate in our country and it is absolutely worrisome the fast establishment of addiction to it. Its immediate effects, that are intense and extremely fleeting, increase dramatically the probability of this drug to be consumed again, settling quickly down the loss of control and the compulsive use, turning the effects of this drug highly addictive. Parallel to this process, brain damages are quickly established, progressing to severe impairments of frontal functions, leading to the lack of cognitive control that feeds back and aggravates the dependence, and hampers any therapeutic approach. The existing treatments have not proved to be satisfactory yet. Thus, considering that a new modality of treatment, based on the neuromodulation induced by noninvasive brain stimulation, has been useful in treating various neuropsychiatric conditions, this study will examine the potential beneficial effects of repeated transcranial Direct Current Stimulation over the left dorsolateral prefrontal cortex in the treatment of crack-cocaine addiction.
The purpose of this research program is to understand how a biomarker called the "nicotine metabolite ratio" (also referred to as NMR) may influence a smoker's ability to quit smoking.
The aim of this study is to determine whether a powerful technique of noninvasive brain stimulation, transcranial direct current stimulation (tDCS), could reduce cigarette smoking and constitute a treatment of tobacco addiction.
