Filter by:The early stages of schizophrenia are associated with significant decreases in social and intellectual abilities, with more declines in chronic disease. Studies have identified relationships between duration of untreated psychosis (the duration between the onset of positive symptoms and treatment) and worse long term outcomes. However, the neurobiology of this phenomenon and its implications for response to antipsychotic medications remain poorly understood. Glutamatergic excess altering brain connectivity might provide an explanation for why those with longer duration of untreated psychosis have worse clinical outcomes. The investigators propose to use neuroimaging to study 67 first episode psychosis subjects before and after sixteen weeks of treatment with risperidone, a common antipsychotic. We will measure (1) glutamate and (2) structural and functional brain connectivity and test the hypotheses that glutamatergic abnormalities are present in first episode patients and that longer duration of untreated psychosis is associated with greater connectivity abnormalities that set the stage for poor response to treatment. 67 demographic-matched controls will also be recruited as a comparison group - healthy controls will not receive antipsychotic medication. The investigator's previous studies have made progress in the understanding of abnormalities in the glutamate system and brain connectivity in unmedicated patients with schizophrenia and modulation of these by antipsychotic medication. Two indices of glutamatergic dysfunction have been identified. While antipsychotic medications appear to modulate glutamate, the disturbance in the relationship between metabolites is not restored with treatment. In addition, the investigators found that both structural and functional connectivity abnormalities in unmedicated patients with schizophrenia predict patients' response to treatment. To the investigator's knowledge, no other group has performed a study that uses a combination of complementary neuroimaging techniques that will allow generating a broad characterization of glutamatergic function and brain connectivity in first episode psychosis and change with treatment. The results of the proposed studies could suggest a mechanism by which the duration of untreated psychosis is associated with poor treatment response which might lead to new interventions to target the illness.
The current protocol pertains to the evaluation of the interactive computer-assisted screening (iCAS) tool through a pilot randomized control trial. The purpose of this evaluation is to determine the efficacy of the iCAS tool in improving clinician's detection of common mental health conditions (i.e. major depression/generalized anxiety/post-traumatic stress disorder/alcohol dependence), and patients' discussion on mental health.
The purpose of this study is to evaluate the efficiency of SSRIs（Selective Serotonin Reuptake Inhibitor） ,ERP（Exposure and Response Prevention） and the combination of the two therapies for OCD(Obsessive-Compulsive Disorder) patients ,at the same time, to find out the biological or psychological predictors of treatment response in Chinese population.
The mortality rate among people with Serious Mental Illness (SMI) is 2 to 3 times that of the general population, meaning that those with a serious mental illness die, on average, 25 years earlier than those without an SMI. These deaths are largely attributed to preventable medical conditions, many of which are more common in the SMI population. The "Bridge" intervention is a peer navigator model that was developed to target factors that negatively impact healthcare access, utilization, and outcomes among individuals with serious mental illness (e.g., severe mood disorders and psychotic disorders). This intervention targets male and female, adult consumers across races/ethnicities and has been utilized by Pacific Clinics (Southern California's largest behavioral healthcare agency) and the Department of Mental Health of Los Angeles County to improve the health and quality of life for their consumers. Investigators will test the comparative effectiveness of a peer navigator intervention (the Bridge) to treatment as usual. The Bridge navigator intervention is designed to teach SMI consumers the skills to engage health care providers and to overcome motivational deficits in order to improve their health and healthcare use. The specific aims of this application are: 1. To use randomized methods to examine the effectiveness of the Bridge intervention on the health care utilization, satisfaction with care, health status, and health care self-management for a sample of individuals with severe mental illness receiving public mental health services in the community; 2. To use randomized methods to examine the effectiveness of the Bridge intervention on psychological and social well-being for a sample of individuals with severe mental illness receiving public mental health services in the community. 151 participants in an Full Service Partnership (FSP) clinic operated by Pacific Clinics were recruited to participate in an approximately 24-month long study of Bridge navigation. Participants will be randomly assigned to either treatment as usual (waitlist) or immediate intervention with the Bridge. Participants in both groups will complete three assessments (baseline, 6 months, 12 months) and statistically compared over time. Staff stakeholders (n = 20) will also be interviewed at baseline and every three months of the study in order to ensure that the intervention is being implemented appropriately.
The primary purpose of this study was to assess the effectiveness of omega-3 supplementation on behavior problems in children.
The aim of this study is to determine whether adherence to oral maintenance medications differs for patients randomized to receive a RxTimerCap, a Take-N-Slide, a standard pillbox, or none of these devices, with the hypothesis that low-touch devices improve adherence over control and that the increase in adherence is agnostic across devices.
Previous research has suggested central nervous system inflammatory activity to be critically involved in disease development and progression in schizophrenia, with a complex interplay of inflammatory mechanisms leading to the development of brain abnormalities and medical symptoms related to schizophrenia. However, the mutual interactions of different inflammatory pathways and their relation to disease course have not been sufficiently studied. This study therefore aims to explore the interaction of neuroinflammatory mechanisms in patients with schizophrenia and to assess whether the inflammatory activity in schizophrenia is state-dependent and occurs mainly during psychotic episodes.
The objective is to test the effectiveness of a village-led microfinance program, Pigs for Peace, on health, household economic stability, and reintegration of trauma survivors to family and community. The five-year experimental trial will use mixed-methods to address the following aims: 1. Determine the effectiveness of a village-led microfinance program on participants health and reintegration in intervention households compared to participants in delayed control households. Health and reintegration will be measured at baseline and six, twelve, and 18-months post-baseline using self-report in both intervention and delayed control groups. We hypothesize that at six, twelve and 18 months post-baseline participants in intervention households will have improved health and increased reintegration to families in comparison to participants in control households. 2. Determine the effectiveness of a village-led microfinance program on household economic stability in intervention households compared to delayed control villages. Household economic stability will be measured at baseline and six, twelve and 18 months post- baseline using self-report in both intervention and control households. We hypothesize that at six, twelve and 18-months post-baseline the intervention households will have improved household economic stability in comparison to control households. 3. Examine the role of a village-led microfinance program on village-level health, economics, stigma and reintegration of survivors and their families in intervention and delayed control villages. Village members (n=5 in each village, n=50 total) will complete a baseline and 18 month post-baseline qualitative interview to examine the role of microfinance on village-level health, economics, stigma and reintegration in both intervention and control households.
The investigators will test the effectiveness of a youth-led animal husbandry microfinance program, Rabbits for Resilience, combined with the adult microfinance, Pigs for Peace (PFP), program on youth, family and community resilience outcomes. The following aims will be completed over the five-year longitudinal, mixed-method, cluster randomized community trial: Specific Aim 1: Determine the relative effectiveness of a youth-led microfinance combined with the adult microfinance on youth and family resilience outcomes (reduced mental health distress, increased economic stability, improved family functioning) compared to a youth-led microfinance only and adult microfinance only approaches. - The investigators hypothesize that at six, twelve and 18-months post-baseline youth and adults in households in the youth-led and adult microfinance approach will report improved individual and family resilience outcomes compared to households in the youth-led microfinance only and adult microfinance only approaches. Specific Aim 2: Determine the relative effectiveness of a youth-led microfinance combined with PFP microfinance on community resilience (e.g. social capital and participation in community groups by youth and adults) compared to youth-led microfinance only and adult microfinance only approaches. - The investigators hypothesize that at 18-months post baseline in households in the youth-led and adult microfinance will report improved community resilience compared to households in the youth-led microfinance only and adult microfinance only approaches Specific Aim 3: Determine if changes in youth resilience (caregiving ability, empathy and outlook for the future) mediate the relationship between youth engagement in microfinance and outcomes, as measured by reduced mental health distress, improved family functioning and improved social capital. Specific Aim 4: Examine youth perspectives on resilience in the context of multiple adversities (war, poverty, loss of family, displacement, victimization). Youth participants (N=50, ages 10-15 years) will be invited (with parent/caregiver consent) to complete at baseline and 18 month post-baseline qualitative interview/group discussion to examine individual, family and community resilience and what that participants perceive as key to buffering the negative health and social consequences of prolonged conflict and other adversities.
