Filter by:The US prevalence of childhood-onset obesity and type 2 diabetes, both predictors of cardiovascular risk, have increased to epidemic proportions in recent decades. Children with mental illness, especially those treated with antipsychotic medications, are at additional risk for obesity (adiposity) and related risk conditions. A variety of noninvasive techniques to assess cardiometabolic risk have begun to be applied in children, including body composition measured with dual energy x-ray absorptiometry (DEXA), carotid intima media thickness (CIMT) measured by ultrasound, and hepatic triglyceride content measured using magnetic resonance (MR) imaging-estimated proton density fat fraction (PDFF). These measures allow for the early, noninvasive study of adiposity-related metabolic risk. The overall aim of this two-study research plan is to characterize the level of measurable risk using these sensitive markers in treated and untreated children with mental health disorders, and to evaluate the magnitude of change in risk that can be observed using these biomarkers in children receiving a well established behavioral weight-loss intervention.
This study will assess the effectiveness of an experimental treatment intervention for adolescents and adults who have experienced their first episode of psychosis during the past two years. The DUP sub-study will collect pathways to care information that will be used to inform the development and pilot testing of strategies that aim to reduce DUP among individuals experiencing a first episode of psychosis.
Background: Among individuals with schizophrenia, there is an increased prevalence of obesity, dyslipidemia ,diabetes mellitus and related conditions such as cardiovascular disease. People with severe mental illnesses, such as schizophrenia, depression or bipolar disorder, have worse physical health and reduced life expectancy compared to the general population. Number of epidemiological studies of patients with schizophrenia have documented a higher incidence of cardiovascular disease than in the general population, and patients with schizophrenia may be at an elevated risk for cardiovascular disease even in the absence of antipsychotic treatment. Affinity for the H1 receptor is most closely linked to increased weight gain, although affinity for D2, 5-HT1A, 5-HT2C and a2-receptors may also be involved. Drug affinity for the H1, M3 and 5-HT2C receptors is correlated with an increased risk of diabetes. High-density lipoprotein cholesterol (HDL-C) concentration in the blood is independently and inversely associated with an increased risk of cardiovascular disease(CVD). However many patients with 'normal' or even 'elevated' plasma HDL experience clinical events. HDL may not always be atheroprotective and in some conditions, it paradoxically enhances the process of atherosclerosis. In addition to its role in reverse cholesterol transport, HDL shows many other protective properties towards atherosclerosis. HDL inhibits the chemotaxis of monocytes , prevents endothelial dysfunction and apoptosis, prohibit slow-density lipoprotein (LDL ) oxidation, and stimulates the proliferation of endothelial cells and smooth muscle cells. These anti-inflammatory, antioxidative, antiaggregatory, anti-coagulant, and pro-fibrinolytic activities are exerted by different components of HDL Aim of the study: To investigate the functional properties of HDL in psychiatric patients before and during antipsychotic therapy. Patients and methods: The blood will be drawn at baseline before the initiation of antipsychotic drugs and 2 months under the antipsychotic treatment. Study procedures: Full lipid profile including triglycerides, LDL-C, Total cholesterol, HDL-cholesterol, apo AI, apoAII and apoB100. Serum Paraoxanase Activity LDL oxidation and resistance to oxidation (measured by conjugated diens formation during incubation in the presence of copper). HDL composition: total and unesterified cholesterol, triglycerides and phospholipids, TBARS content before and after exposure to AAPH as a major indicator of oxidative stress, PON activity using phenylacetate as a substrate, apoA1and PAF. Serum parameters e.g. Diacyl glycerol acyltransferase activity, free ApoA1 and LCAT activity. 3 [H]-Cholesterol efflux will be measured by incubating J744 macrophages with serum. Radioactivity will measured by β counter in the cell lysate and the medium. Statistical methods: One-way AVOVA and Student's t-test for paired samples will be used for comparison of multiple groups and paired samples, respectively. p<0.05 will be considered significant.
Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED.

The current study aims to evaluate the impacts of yoga and aerobic exercise on neuro-cognitive function, symptoms and brain changes in early psychosis. A total of 120 female subjects who aging from 18-55 years old, and diagnosed with psychotic disorders within the past 5 years, will be randomized into 3 groups: 1) yoga therapy, 2) aerobic exercise, and 3) waitlist group as the control. All groups will try to be kept consistent with their medication with no more than 25% change in their entry level dosage for at least six weeks. The primary outcomes of the present study will be neuro-cognitive changes; the secondary outcomes will be changes of brain structure and function.
A total of 160 subjects, who aged 18-35 and had completed the first 2 years of case management in the EASY programme will be randomized in 1:1 ratio into either (1) receiving an additional year of case management, or (2) terminating case management for the next 12 months. The current study aims to investigate whether an additional year of case management in year 3 will confer additional benefits in outcome, in terms of functioning, symptoms, quality of life and health economics.
This study will evaluate clinical efficacy and safety of treatment with YY-162 in children with ADHD
This study is designed with the aim to evaluate the clinical effect of the overlapped switching to ziprasidone as well as the efficacy and safe metabolic profile of ziprasidone.
During the 1990s, evidence began to emerge of the long duration of untreated illness prior to receiving treatment for patients with psychotic disorders. Studies across the world on first episode psychosis have consistently found an average of 1 - 2 years between the onset of psychotic symptoms and the start of treatment. Lengthy treatment delay has immediate implications such as unnecessary distress for patients and families, and may also compromise potential recovery when treatment is initiated.By understanding how and why substantial delays occur the investigators may be able to better design interventions to facilitate better earlier treatment. The components of DUP can be conceptualised as comprising 3 distinct intervals: help-seeking delay, referral delay and delay in mental health services. In this study the primary aim is to establish the level of DUP in nordland, and explore the components of this variable. Help-seeking delay will be investigated by interviewing patients presenting at the central mental health hospital in Nordland about their psychosis onset and pathways to care. Referral delay will be investigated by a questionnaire about the referral pratices among GPs in Nordland. Delays in mental health services will be investigated by focus group interviews with leaders and professionals at the 7 community mental health centers in Nordland. This knowledge is believed to be crucial for developing services that can reduce DUP and give this patient population earlier access to adequate treatment.
