Filter by:This prospective cohort study assesses the effects of exposure to organophosphate (OP) pesticides on adverse reproductive outcomes in both male and female agricultural workers in China. We will enroll women and their spouses, who are attempting to become pregnant, and observe reproductive endpoints including (1) semen parameters (concentration, total count, motility, progression and morphology), (2) menstrual disorders (oligomenorrhea, amenorrhea, polymenorrhea, intermenstrual bleeding, prolonged menstrual bleeding, dysmenorrhea, and irregular menstruation); (3) alterations in hormone patterns including reduced estrogen excretion (REE), anovulation, abnormal luteal phase (ALP), and abnormal follicular phase (AFP) in women and abnormalities of LH, FSH, TSH, SHBG, inhibin-B and testosterone in men; (4) fecundability; and (5) pregnancy outcomes including spontaneous abortion, preterm delivery, low birth weight, and intrauterine growth retardation.
This study will evaluate the effectiveness of electroconvulsive therapy (ECT) administered with medication for the treatment of a major depressive episode (unipolar or bipolar) and will compare two types of ECT.
The purpose of this study is to evaluate the effectiveness and safety of risperidone to augment SSRI therapy in patients with treatment-resistant depression and to demonstrate the long-term maintenance effect of risperidone as augmentation therapy compared with placebo augmentation in these patients.
This study will compare the effects of an acute dose of lorazepam to a placebo in elderly patients with generalized anxiety disorder (GAD).
The purpose of this study is to learn more about Obsessive-compulsive Disorder (OCD) in children. OCD usually has a slow onset, and symptoms that may remain at a stable level over time. A subset of children with OCD has a sudden onset and symptoms that fluctuate in severity over time. This study will also compare healthy children to those with OCD. This is an observational study; children who participate will not receive any new or experimental therapies. OCD affects nearly 1% of the pediatric population. The symptoms of this illness can interrupt development, causing significant psychological distress and producing life-long impairments in social, academic, and occupational functioning. A subgroup of pediatric OCD has been designated by the acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections). This type of OCD is characterized by sudden symptom onset and a relapsing-remitting course of illness; exacerbation of symptoms occurs with scarlet fever or strep. throat infections. This study will identify factors that distinguish children with PANDAS OCD from children with non-PANDAS OCD, and will compare both groups to healthy children. Children with OCD and their parents are screened with interviews and a review of the child's medical records. Participants have an initial evaluation that includes a psychiatric, physical and neuromotor exam, neuropsychological testing, psychological interviews, and a blood test. Structural magnetic resonance imaging (MRS) scans of the brain are also obtained. The MRS scan does not use radiation. After the initial evaluation, children with OCD have follow-up visits every 6 weeks for 12 to 24 months. They are seen yearly for 8 years after the study. If they have a significant improvement or worsening of their symptoms, they are asked to make a maximum of two extra visits. Parents of OCD patients are called four times a year to discuss any changes in the child's condition between yearly visits. All participants have a 1-year follow-up visit upon study completion.
Olanzapine is currently marketed for the treatment of schizophrenia and acute manic episodes with bipolar 1 disorder. This Anti-obesity Agent is currently marketed for the management of obesity. In this study, the Anti-obesity Agent is being tested to see if it can treat weight gain that may be associated with taking olanzapine. The purposes of this study are to determine the safety of olanzapine when given in combination with the Anti-obesity Agent and any side effects that might be associated with it and whether weight-gain agent can help treat weight gain that may be associated with taking olanzapine.
This study will evaluate a family intervention program for individuals with bipolar disorder, schizophrenia, or schizoaffective disorder and co-occurring substance use disorders.
A clinical study to determine the efficacy and safety of MK0869 in the treatment of depression.
The purpose of this study is to determine if duloxetine is effective when compared to placebo in preventing recurrence of major depressive disorder in patients who have responded to open-label duloxetine treatment.
The purpose of this study is to determine the safety and efficacy of topiramate in adolescents with manic or mixed episodes of Bipolar I Disorder.
