Filter by:The purpose of this study is to develop and evaluate a 9-month psychosocial intervention that will assist patients with hepatitis C in overcoming barriers that prevent them from becoming appropriate candidates for interferon therapy.
Cigarette smoking decreases life expectancy, causes devastating health complications, and costs society billions of dollars each year. These untoward consequences are especially pronounced among persons with schizophrenia (SCZ) because approximately 80% to 95% of this group smokes cigarettes. These high prevalence rates underscore the need for research investigating the determinants of smoking in patients with SCZ. Several researchers have observed that nicotine improves specific symptoms of SCZ including negative symptoms, negative affect, and cognitive deficits. This has led to the hypothesis that patients with SCZ smoke in an attempt to self-medicate. However, the mechanism(s) by which nicotine has its positive effect on symptoms remains unclear. The current proposal posits that neural inhibition (NI) is a physiological mechanism of this effect, while variation in the alpha-7-nicotinic receptor subunit gene (CHRNA7) represents the genetic underpinnings of these processes. The proposed study will assess NI and symptom improvement after acute administration of nicotine to both smokers and nonsmokers with SCZ. In addition, NI and CHRNA7 variation will be tested as predictors of patients' ability to reduce/quit smoking following smoking treatment. These data may lead to the development of new pharmacological strategies for treating the symptoms of SCZ and new methods for assisting these patients to quit smoking.
A three-arm, randomized, double-blind, placebo-controlled, Phase 4, multicenter study to compare the efficacy and safety of atomoxetine versus placebo in children and adolescents aged 6 through 17 years with attention-deficit/hyperactivity disorder (ADHD) and comorbid oppositional defiant disorder (ODD) who are treated as outpatients in Germany. After an initial 3- to 28-day screening and washout phase, participants will be assigned to double-blind treatment with atomoxetine or placebo. A 2 week up-titration period will be succeeded by a 7 week treatment period at the target dose. The primary efficacy measure will be the Swanson, Nolan and Pelham Rating Scale Revised (SNAP-IV) ODD subscale score.
The purpose of this study is to determine whether individuals with obsessive compulsive disorder who will take a preparation of the amino acid glycine in addition to their current treatment, may experience improvement in their symptoms.
This study will examine the effectiveness of a multiple family group mental health service delivery strategy in improving mental health service use and outcome for urban, low income children of color, ages 7-11 years old with disruptive behaviors and their families.
This study will evaluate the effectiveness of a parent training program in improving parenting skills and reducing behavioral symptoms in young children who are at risk for developing childhood behavior disorders.
The purpose of this study is to determine the effects and cost-effectiveness of a Diagnostic Observation Center for PsychoGeriatric patients (DOC-PG). Our main hypothesis is that DOC-PG has added value compared with usual care regarding Health Related Quality of Life (HRQoL).
The aim of this project is to analyze the impact of a psycho-educational group program on the family members and close friends of persons with eating disorders and co-morbid personality disorders.
The purpose of this study is to determine whether Recovery Guide support services are effective in promoting recovery and social integration among psychiatrically disabled individuals who experience high rates of inpatient hospitalizations.
This study is being done to look at how well people respond to two very different drug treatments for depression. Clinically, people with depression can respond differently to drug treatments for reasons which are not always clear. Some of our own recent research suggests that people with depression who have a family history of bipolar disorder or completed suicide, may react differently to standard antidepressant medications than those without such a family history. Our data shows that family history of completed suicide, as well as the known predictor of family history of bipolar disorder, may help identify a pre-bipolar high risk group i.e. they currently have depression but at some future date will declare a bipolar illness (manic-depression) by virtue of development of a manic episode also. Our research suggests that treatment- emergent symptoms in response to a trial of antidepressant, such as agitation may be strong predictors of future bipolarity and inherently dangerous particularly as they are not ascribed to the antidepressant treatment. Finally, it is possible that this subgroup of those with depressive illness may respond better and more safely to lithium, a mood stabiliser used in known bipolar depression. The objective of this proposal is to investigate response to acute lithium treatment in subjects who meet the diagnostic criteria for major depression, but who are potentially at risk for bipolar disorder, by virtue of family history of bipolarity or completed suicide.
