Brain Cell Injury in Patients With A First Episode of Psychosis
PsychosesPatients experiencing a first episode of psychosis may have brain cell damage due to a chemical process called oxidation. This study will compare patients with psychosis to healthy volunteers to determine if there are differences in their blood that reflect oxidative brain cell damage.
Study of Children at Risk for Disruptive Behavior Disorders
Attention Deficit and Disruptive Behavior DisordersChild Behavior Disorders1 moreA conduct disorder is characterized by repetitive and persistent patterns of behavior where the basic rights of others and rules are violated. This study investigates characteristics of children and their surroundings (environments) that place them at risk for the development of disruptive behavior disorders and associated disorders of anxiety and mood. Children ages 4 - 5 with moderate (subclinical) and severe (clinical) rates of misconduct during the preschool period are compared to low risk children. Children and their families were recruited from 1989-1991 and are being studied at five specific times: Preschool (4 - 5 years) Early childhood (6 - 7 years) Middle childhood (9 - 10 years) Early adolescence (13 - 14 years) Mid-adolescence (15 - 16 years) Researchers will look closely at biological, intellectual, emotional, and behavioral factors that are thought to protect against and/or increase the risk of developing a conduct problem. These factors have been studied in older children and are shown to be associated with disruptive behavior disorders. The goals of this research study are; Create a database showing the characteristics of the development of disruptive behavior problems. Identify the key risk and protective factors that contribute to the stability or change in behavior problems over time. Identify the ways that children interact socially and relate them to the possibility of developing a problem of behavior. Identify how experiences and the emotions associated with experiences may play a role in the development of related psychiatric conditions, like depression and anxiety. Establish measures of the different components of negative emotions associated with disruptive/antisocial, anxiety, and mood disorders.

SchizophreniaMental Disorder6 moreThe involvement of family members is crucial and improves the prognosis of psychiatric patients and reinforces therapeutic adherence and reduces the frequency of relapses. For schizophrenia, the scientific literature clearly shows that it's in the interest of the patient to offer to his family a psychoeducational program. Therapeutic education programs are now part of the recommendations of good clinical practice and in the French health through the law n ° 2009-879 of July 21, 2009 on the reform of the hospital and relating to patients, health and territories.
The BC Psychosis Program Biobank and Database for Genetic Polymorphisms and Their Associations With...
PsychosisSchizophreniaThe purpose of this study is to determine if candidate polymorphisms in brain-derived neurotrophic factor (BDNF) and catechol-o-methyl transferase (COMT) are predictive of psychosis disorder severity, symptomology, and resolution in patients at BCPP. A secondary objective will be to form a biorepository of blood and saliva samples from patients at BCPP so that further genetic, proteonomic and pharmacogenomic studies may be done to gain insight into the genetic basis of differences in psychosis disorder presentation and manifestation, and differences in response to antipsychotic drug treatment.
Assessment of Child Psychological Attributes for Prediction of Child Behavior at First Dental Visit...
Psychological DisordersOne of the most prevalent chronic diseases worldwide is mental disorder, including social, emotional, and behavioral problems, and it is the fifth main cause of global disability . In Egypt, it is estimated that 20.6% of children aged from 6-12 years had behavioral problems Behavioral and emotional problems may affect deeply child's quality of life, such as impairment of school life (high absence), They may cause nutritional imbalance and even suicidal thoughts. Therefore, both the dentist and the family should be adequately prepared to deal with those children who come seeking dental treatment. Recently, studies proved the association between the psychological characteristics and the behavior of children in dental setting. There was a study that showed that there is a relation between psychological functioning of the child, dental anxiety and his/her behaviour during dental appointment. Furthermore, it was found that there is a correlation between the temperamental difficulties or emotional problems of the child and the non-cooperative behavior during the process of injection of the local anesethia. These studies ensures the importance of understanding the effect of mental disorders on the behavior of children during dental treatment, as it would help the professionals to properly plan the clinic appointments without any delay or cancellation of the appointment and allows him to render effective and efficient dental treatment.
Citalopram and Stress Reactivity
DepressionDepressive Disorder4 moreThis study is investigating whether acute administration of citalopram is associated with a decrease in stress reactivity in healthy volunteers, compared to placebo administration. Using a parallel-group double-blind design, participants will be randomised to receive either an acute dose of citalopram or placebo. All participants will have come in for a screening visit. On the day of the research visit (following drug administration) participants will have completed a number of widely used computer-based cognitive tasks measuring emotional processing biases. They will then complete the Oxford Cognition Stress Task, a web-based acute stress induction paradigm, which is designed to induce mild transient increases in stress and arousal. Identifying early changes in stress reactivity following antidepressant treatment will increase the investigator's knowledge of how antidepressants operate, and provide putative targets to identify early response to antidepressants.
Study on Predictiors and Mechanism of Conversion to Psychosis in Individuals at Ultra-high Risk...
SchizophreniaConsidering the complex pathological mechanism and the poor treatment outcomes of schizophrenia, early detection and intervention gradually become the key work for the foundational and clinical research in schizophrenia. Ultra-high risk for psychosis (UHP) is defined as individuals at the prodromal stage of schizophrenia. Early intervention in individual at UHP can effectively delay or even prevent the development of the illness. Long-term longitudinal studies suggested that there are clinical outcomes in people at UHP. Nearly 1/3 of individuals at UHP may be naturally relieved without any intervention, about 1/3 of individuals at UHP will remain at the prodromal stage of schizophrenia, and only 1/3 individuals at UHP will eventually develop schizophrenia. In this regard, it will cause adverse effects on false positive individuals if they accept clinical intervention. Unfortunately, it is difficult to accurately predict which individuals at UHP will make a transition to frank illness. To solve this issue, we explore the association between baseline brain structural and functional networks, methylation modifications, gene expression, neurocognitive function and the clinical outcomes of UHP individuals, and to identify the potential biological and clinical predictors for the long-term outcomes in the individuals at UHP. In addition, we also detect the changes of brain structure and function, methylation status and gene expression in individuals at UHP during follow-up, and further to investigate the etiology and pathogenesis of schizophrenia.

Severe Mental IllnessRehabilitation1 moreThe objective of the proposed study is to take a further step in this direction by developing, implementing and monitoring a routine systematic evaluation of clinical process and outcome indicators, patient reported experience (PREMs) and patient reported outcomes (PROMs) to study the quality and continuity of care over time.
The Covid-19 HEalth caRe wOrkErS (HEROES) Study
Covid-19Mental Health Disorder4 moreSince December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
