Background: - Individuals who are dependent on alcohol often have feelings of anxiety, irritability, anger, and depression. These feelings, as well as stress, may contribute to the risk of relapse and continued drinking. Studies have shown that alcohol consumption increases the activity of certain molecules in the brain known as CRH1 receptors, which are key to producing the body s response to stress, and whose activation generates feelings of anxiety. Researchers are interested in learning whether the experimental drug pexacerfont, which blocks CRH1 receptors and has been studied in individuals with anxiety disorders and depression, can lessen anxiety and craving for alcohol as part of alcohol-dependence treatment. Objectives: - To determine the safety and effectiveness of pexacerfont as a treatment for anxiety-related alcohol craving. Eligibility: - Individuals between 21 and 65 years of age who are alcohol-dependent and have problems with anxiety. Design: - This study requires an inpatient admission to the NIH Clinical Center for approximately 1 month, with two additional study visits 1 week and 1 month after discharge from the hospital. - Participants will be screened with a medical history, physical examination, and blood and urine tests. - During the inpatient period, participants will have standard treatment for alcohol dependence, including support and interventions from institute staff to address cravings, anxiety, or other psychological problems. Participants will not receive formal psychological treatment or psychiatric medications for anxiety, but will receive training in relaxation techniques. - Participants will be assigned to take either pexacerfont or placebo for 3 weeks. During this time, participants will have the following procedures: - Frequent blood tests. - Rating scales and questionnaires about alcohol cravings and anxiety. - Dexamethasone suppression test with frequent blood draws to study hormone response to stress. - Social stress test involving public speaking, followed by blood samples and questionnaires on alcohol craving. - Cue Reactivity (CR) session to study cravings and responses to alcohol-based cues. - Functional magnetic resonance imaging scan to evaluate brain activity while taking the medication or placebo. - Participants will have two follow-up visits for additional blood tests and questionnaires about the effects of the treatment ^.
Background: - Researchers studying new treatments for major depressive disorder are looking at how medications to treat depression act on the brain chemical serotonin, which interacts with specific serotonin receptors on brain cells. New methods of studying serotonin receptors in the brain may help provide a better understanding of depression and treatment options. - A new radioactive chemical called [11C]CUMI may be useful for studying serotonin receptors in the brain. By using positron emission tomography (PET) scanning to see how [11C]CUMI bonds with serotonin receptors, researchers will investigate whether [11C]CUMI can be used to study depression and how antidepressant medications work. Objectives: - To determine the usefulness of [11C]CUMI as a method of studying serotonin receptors in the brain. Eligibility: - Healthy individuals between 18 and 65 who have no history of psychiatric illness. Design: - This study requires 8 outpatient visits to the NIH clinic. - Visit 1: Participants will have a full physical examination and medical history, as well as a psychiatric evaluation and questions about alcohol and drug use. Other tests will include blood and urine samples and an electrocardiogram (EKG). Testing will take approximately 3 hours. - Visit 2: Participants will have a magnetic resonance imaging (MRI) scan to evaluate brain function and activity. - Visit 3: Participants will have a PET scan, in which a small amount of the radioactive chemical [11C]CUMI will be injected through an intravenous (IV) catheter, and will have another IV line put in place to draw regular blood samples during the scan. The scan will last approximately 4 hours. - Visits 4-8: Participants will have regular blood tests after the scan between days 1-3 and at about weeks 1, 2, 3, and 4. The blood tests will check muscle, heart, and liver function.
Adolescent substance abuse results in significant negative outcomes and extraordinary costs for youths, their families, communities, and society. Moreover, rates of psychiatric comorbidity among substance abusing youth range from 25% up to 82%, and youths with a dual diagnosis are more than twice as costly to treat compared to those with no comorbidity. The applicant principal investigator recently completed a pilot project funded by the National Institute on Drug Abuse focused on developing and piloting a psychosocial treatment specifically for youth presenting for outpatient treatment with co-occurring substance use and internalizing (i.e., mood and/or anxiety) problems. Results were promising with the experimental group exhibiting significantly less substance use and more rapid reductions in anxiety and depressive symptoms compared to the control group. The proposed research is a randomized clinical trial (RCT) to compare the experimental treatment (OutPatient Treatment for Adolescents; OPT-A) to an "active placebo" on key clinical indices from pre-treatment through 18 months. The proposed RCT (n = 160) employs the treatment manual, quality assurance protocol, and therapist training protocol developed and successfully tested in the pilot study, to evaluate the efficacy of OPT-A for youth referred to outpatient treatment of co-occurring substance use and internalizing problems. The following outcomes will be evaluated: drug use; mental health; behavioral, school, peer, and family functioning; and consumer satisfaction. The intervention addresses one of the more prevalent and most challenging, costly, and understudied presenting problems among adolescent outpatients. If successful, this research could provide a considerable contribution in the treatment field for youth with co-occurring substance use and internalizing disorders.
RATIONALE: Gathering information about how patients, caregivers, and healthcare professionals cope with symptoms caused by lung cancer, such as breathlessness, cough, fatigue, anxiety, depression, pain, and difficulty sleeping, may help doctors learn more about non-drug methods of treating symptoms of respiratory distress. PURPOSE: This clinical trial is studying how caregivers help patients cope with respiratory and other symptoms caused by lung cancer.
RATIONALE: Acupressure wristbands may prevent or reduce nausea caused by chemotherapy. It is not yet known whether acupressure wristbands are more effective than standard care in controlling acute and delayed nausea. PURPOSE: This randomized phase III trial is studying acupressure wristbands to see how well they work compared with standard care in controlling nausea caused by chemotherapy.
A pilot study to evaluate the ability of photobiomodulation to alter cerebral blood flow in the frontal poles and to affect the emotional status of patients with major depression.
RATIONALE: Acupuncture may help relieve fatigue caused by breast cancer. It is not yet known whether acupuncture is more effective than self-acupuncture in managing fatigue in women with breast cancer. PURPOSE: This randomized phase III trial is studying acupuncture to see how well it works compared with self-acupuncture in managing cancer-related fatigue in women who have received chemotherapy for stage I, stage II, or stage IIIA breast cancer.
RATIONALE: Collecting information about the effect of hematologic cancer and its treatment on quality of life may help doctors learn more about the disease and plan the best treatment. PURPOSE: This phase I trial is studying quality of life in younger leukemia and lymphoma survivors.
RATIONALE: Mindful movement is a self-directed activity of mindfulness (intention, attention, and attitude) and physical movement. A mindful movement program may be effective in improving well-being in older women who are breast cancer survivors. PURPOSE: This randomized clinical trial is studying how well a mindful movement program works in improving quality of life in older female breast cancer survivors.
