Filter by:The study seeks to delve into the firsthand experiences of patients diagnosed with schizophrenia who partake in a separate clinical trial featuring a specific medical intervention. The primary emphasis will be on meticulously tracking the rates of trial completion and withdrawal among these individuals. The data collected from this study will help improve future outcomes for all schizophrenia patients as well as those in under-represented demographic groups.
Historically, research participation has been biased toward certain demographics. However, there is a shortage of studies that delve into the underlying factors that influence patient participation, both positively and negatively. Several people will be invited to enroll in this study so that it may collect a variety of data about schizophrenia clinical trial experiences and identify barriers to participation as well as the causes of participants' failure or withdrawal. The data collected from this study will be analyzed and used to improve the experiences of future schizophrenia patients who are recruited for medical trials.
Primary objective: To examine the impact of the sustained use of the health app and smart body fat scale on weight management and patient engagement Secondary objectives: 1. To compare the difference in weight loss between the participants who have good compliance to app + scale protocol and the participants who have bad compliance 2. To evaluate the longitudinal association between self-monitoring adherence and percent weight loss. 3. To evaluate the prospective association between monthly % weight loss and the subsequent month of self-monitoring adherence List the clinical hypotheses: 1. At least 50% of participants will achieve 7% weight reduction compared with baseline by self-weight monitoring using smart body fat scale and health app. 2. The self-monitoring adherence is associated with greater weight loss. 3. The monthly weight loss is associated with the subsequent month of self-monitoring adherence. 4. The self-weight monitoring using smart body fat scale and health app are feasible by evaluating the compliance and completeness of the data.
The purpose of this study was to explore whether repeated oral fecal capsules could improve outcomes in patients with schizophrenia receiving conventional antipsychotic drugs. This study was divided into screening period (1 week) and treatment period (8 weeks). Subjects who met the inclusion criteria during the screening period entered the treatment period. During the treatment period, the patients were divided into two groups: oral fecal bacteria capsules + antipsychotics group; Oral placebo + antipsychotic group. During the follow-up period, both groups were treated with stable dose of antipsychotic drugs during the treatment period. Before and after the intervention, venous blood samples of patients were collected for routine tests such as liver and kidney function to determine the safety of treatment. The scale evaluated the improvement of patients' psychotic symptoms to determine the efficacy and safety of FMT combined with antipsychotics.
Schizophrenia is a severe chronic mental disorder with a long-term treatment. Most antipsychotic (AP) drugs are effective for only 30% to 60% of patients and for many drugs, treatment selection remains a "trial-and-error" process.The main result of treatment inefficiency is relapse, the recurrence of acute symptoms after a period of partial or complete remission. Pharmacogenetics (PG) is the study of genetic differences in drug met-abolic pathways which can affect individual responses to drugs, both in terms of therapeutic effect as well as adverse effects. PG testing could therefore identify patients at potentially high risk of relapse allowing the opportunity of an individualized prescription. In this study, PG was shown to improve the safety profile of AP treatments in patients presenting PM or UM CYP variants, by reducing associated side effects. Therapeutic Drug Monitoring (TDM) is the quantification and interpretation of drug concentration in blood to optimize pharmacotherapy . For drugs with established therapeutic reference ranges (TRR) or with a narrow therapeutic index, it makes sense to measure drug concentrations in blood for dose titration after initial prescription or after dose change. Non adherence is a recurrent problem in the management of schizophrenia, leading to reduced quality of life and increased risk of relapse. TDM is recognized as a direct reliable measure for drug adherence and can be an additional support after a therapy adjustment. Additionally, TDM can be useful to educate patients and make them more aware of their treatment. Finally, TDM is likely to ensure a better tolerance and fewer side effects for APs, while allowing a better efficacy. However, evidence on the clinical impact of this tool in schizophrenic population is lacking and randomized clinical trials are needed to confirm it. Finally, relapses occur frequently in schizophrenia and the cost for a relapsing schizophrenic patient is estimate over 4 times higher than for a non-relapsing patient, highlighting the importance of cost-effective care strategies. When separately used PG testing or TDM alone, might not be sufficient to ensure the clinical utility and cost-effectiveness of these tests. We hypothesize that individualized medicine including the association of PG testing with TDM (PG/TDM intervention), on the most commonly prescribed AP drugs, can reduce relapse rate at one year while being cost-effective.
The COVID-19 pandemic significantly impacted primary care across Canada. Inequities in prevention activities and chronic disease management likely increased but the extent is unknown. Pragmatic interventions are required to prioritize patients and improve the quality of primary care post-COVID. In AFTERMATH, the investigators will conduct a pragmatic cluster randomized controlled trial (cRCT) at the largest primary care Practice-Based Research Network (PBRN) in Ontario, focused on a highly marginalized population: adults living with mental illness and one or more additional chronic diseases. The investigators will test an intervention that builds on the investigators' past work and combines data and supports to primary care providers to improve quality of life, reduce gaps in prevention activities and improve chronic disease management. The investigators' project will result in new evidence on ways to improve access to care and reduce inequities, and inform future efforts to use data beyond COVID-19.
This mixed-method study aims to examine the feasibility of delivering tgCBFI programme to dyads of people with schizophrenia and their family caregivers, and generate preliminary evidence on the effectiveness of tgCBFI in reducing expressed emotion. The research questions are as follows. 1. What are the feasibility, acceptability, and safety of conducting a tele-group CBFI programme for people with schizophrenia and their family caregivers? 2. What effect does tgCBFI have on the expressed emotion experienced by adults with schizophrenia and the caregiving experience of their family caregivers at posttreatment and 12-week after completion of the programme? 3. What effect does tgCBFI have on the positive and negative symptoms of adults with schizophrenia and the perceived care burden and level of mood disturbance of their family caregivers at posttreatment, and 12-week after completion of the programme?
This study aims to evaluate the tDCS's impact on cannabis craving in patients with schizophrenia and cannabis addiction disorder.
Low social motivation is a significant symptom of schizophrenia and is a major cause of disability and suffering for many patients struggling with the illness. Social motivation refers to the drive to participate in or abstain from social activities. Many patients with schizophrenia evidence both decreased drive to seek positive social input (approach motivation) and heightened drive to avoid negative social input (avoidance motivation) compared to individuals without the illness. Despite the enormous burden of these deficits on patients, there are no medications that effectively treat impaired social motivation. Buprenorphine is an unusual drug that is used to treat opioid use disorder at higher doses and more recently, to treat depression and suicidality at lower doses. It is a unique opioid medication that has a compound action that gives it the potential to improve social motivation both by boosting approach motivation and by reducing avoidance motivation. The effects of low doses of buprenorphine have previously. been studied in healthy volunteers, showing that the drug enhances social motivation. These results in nonclinical volunteers suggest that buprenorphine may be a promising treatment for deficits in social motivation seen in some patients with schizophrenia. However, no previous studies have investigated the effects of buprenorphine on social motivation in this population. Here the effects of a low dose of buprenorphine (0.15mg) on social motivation in patients with schizophrenia (N=40) will be assessed. In this double-blind, cross-over, placebo-controlled study, participants will attend a 2-hour preparatory session and two 6-hour laboratory sessions, at which they will receive either placebo or buprenorphine. During expected peak drug effect they will complete validated tasks assessing social motivation. It is expected that buprenorphine will increase approach motivation and decrease avoidance motivation as measured by an attention bias task. The results of this study will lay the foundation for the clinical use of buprenorphine as the first medication to treat social deficits in schizophrenia.
Impaired social motivation, or "asociality," is a negative symptom of schizophrenia (SCZ) and a cause of significant functional impairment in the illness. Whereas many symptoms of schizophrenia can be treated with antipsychotic medications, deficits in social motivation persist, leading to significant social disability in patients. There is currently no effective treatment for this symptom of the illness. One promising and unexplored avenue to enhance social motivation in schizophrenia is ± 3,4-methylenedioxymethamphetamine (MDMA). MDMA is a psychostimulant that shares some pharmacological properties with amphetamines, but in addition, has pronounced pro-social effects, increasing the motivation to engage socially. In healthy volunteers, it produces feelings of empathy and closeness with others and increases attention to positive social cues, perhaps partly through its effects on the social bonding hormone, oxytocin. MDMA has shown promise in other psychiatric conditions such as PTSD. Thus, MDMA could offer a unique therapeutic benefit in patients with SCZ who suffer from impaired social motivation. The investigators plan to take the first step in testing MDMA as a treatment for these social deficits by testing the tolerability of the drug in patients with SCZ. This will be an open-label, ascending-dose, within-subject trial in which participants will receive 40mg, 80mg, or 120mg of MDMA. The doses will be administered in ascending order, but doses will be stopped if subjects experience moderate or greater psychotic symptoms at 24 hours. This trial will assess the tolerability of the drug in this population and guide in the selection of a maximum well-tolerated dose for future studies. The primary tolerability measure will be clinician-rated psychotic symptoms (disorganized speech, delusions, hallucinations) collected at 24 hours after MDMA administration. The results of this project will lay the foundation for further investigations of MDMA and other psychoactive compounds as a treatment for debilitating and difficult-to-treat social deficits in schizophrenia. Future studies will examine interactions between the effects of psychoactive compounds and nonpharmacologic psychosocial interventions targeting social symptoms.
