Smokers with schizophrenia spectrum disorders have high rates of morbidity and mortality from smoking-related diseases compared with the general population and current options for smoking cessation in this vulnerable group are unsatisfactory. Considering that most people with schizophrenia spectrum disorders continue smoking, it is urgent to consider alternative and more efficient interventions to reduce or prevent their morbidity and mortality. Switching to combustion-free technologies for nicotine delivery (I.e. e-cigarettes) could be a pragmatic and much less harmful alternative to tobacco smoking with the possibility of significant health gains. Emerging research is suggesting that ECs may be useful for smoking cessation and relapse prevention in people with schizophrenia spectrum disorders. In particular, a study conducted with JUUL e-cigarette with 5% nicotine strength showed that this product had sufficient nicotine delivery and product appeal to determine high success rates in heavy smokers with schizophrenia spectrum disorders. In consideration of these preliminary findings, we hypothesized that switching smokers with a schizophrenia spectrum disorder diagnosis to JUUL e-cigarette with 5% nicotine strength could result in higher success rates compared to JUUL e-cigarette with 1.7% nicotine strength. Recent work indicates that nicotine PK of the JUUL e-cigarette with 5% nicotine strength (a device that utilizes a nicotine salt formulation) approximates the nicotine delivery of combustible cigarettes and that the 5% nicotine strength product is far more efficient in delivering nicotine compared to the sister product with 1.7% nicotine strength. Both products are identical in their appearance, making them suitable for a double-blind study design.
In times of pandemics, social distancing, isolation and quarantine exacerbate depression and anxiety as confined people are detached from their loved ones, deprived of personal liberties, and devoid of purpose owing to altered routine and livelihood (1,2). Those with pre-existing mental health problems or illnesses (MHPIs) might suffer from limiting interpersonal interactions that are central to their self-management, as well as reduced access to helpful but "non-essential" (often cancelled) psychiatric services (3). In response to this situation, this feasibility study of a trial consists of offering a transitional measure of online peer support for people suffering from (a) psychotic disorders or (b) anxiety and mood disorders, and to determine an effect size to this Peer Support Workers-delivered intervention in terms of both personal-civic recovery and clinical recovery (4). Peer Support Workers (PSWs) are persons with first-hand lived experience of MHPIs, and who are further along in their own recovery journey. As recommended by recovery-oriented best practices guidelines (5,6), upon training and certification they can provide supportive services when hired to fill such a paid specialty position directly in, or in conjunction with, current psychiatric services. Indeed, recovery focuses on how individuals can have more active control over their lives (agency). It is characterized by a search for the person's strengths and capacities, satisfying and meaningful social roles, and mobilizing formal and informal support systems. Peer support has thus become one predominant concept in the recovery paradigm and PSWs are specialized in peer support. Yet, not much is known about the efficacy of PSWs from a consumer's perspective of personal-civic recovery. The five principal research questions are whether this online intervention will have an impact in terms of (Q1) personal-civic recovery potential and (Q2) clinical recovery potential, (Q3) how these potentials can be impacted by the COVID-19 pandemic, (Q4) how the lived experience of people in recovery can be mobilized to cope with such a situation, and (Q5) how sex and gender considerations can be taken into account for the pairing of PSWs with service users, beyond considerations based solely on psychiatric diagnoses or specific MHPIs.
Schizophrenia is one of the most consumptive diseases, which brings great loss to patients and their families, and even to the society. Clinical High Risk for Psychosis (CHR) is a concept put forward on the basis of the prodromal stage of schizophrenia. Over the past 20 years, the identification and intervention of CHR has become the focus of psychiatric research, with the primary goal of early identification of biomarkers of susceptibility to schizophrenia and the development of individualized interventions to prevent or delay progression. Longitudinal studies have shown that CHR converted to schizophrenia mainly within two years, with a risk of about 30 percent. Self-disorder is one of the core characteristics of schizophrenia. The two most basic experiences of self-representation are sense of ownership and sense of agency. Sense of ownership refers to the sense that "I" perceives "my" body, while sense of agency refers to the sense that "I" experiences "my" actions and their consequences are initiated by "me". Some studies have shown that patients with schizophrenia show defects in the sense of ownership and agency. The most commonly used paradigm for observing "sense of ownership" and "sense of agency" is the rubber hand illusion (RHI) or the virtual hand illusion (VHI). In this study, the VHI experimental paradigm will be used to detect the self-representation of the individuals at high risk for psychosis, and the clinical outcome will be observed for one year.The hypothesis is that the subjects who exhibit abnormal illusion experience in VHI experiment are more likely to transition into psychotic disorders.
The purpose of this study is to investigate the efficacy of an integrated mental health care and vocational rehabilitation intervention for people on sick leave because of depression, stress, anxiety, personality- and functional disorders in Denmark
The main aim of the study is to evaluate the effectiveness of Individualized Meta-Cognitive Training (EMC +), in people with psychosis of brief evolution on symptoms, especially on positive symptoms. Secondary aims would be to assess the effect of EMC+ in metacognition, psychosocial and neuropsychological functioning, and to assess the maintenance of program effects on 6 months.
This study aims to explore whether hormones or inflammatory markers are associated with cognitive changes following cognitive remediation therapy (CRT) in people with a recent-onset psychotic disorder. The following biomarkers for treatment response will be considered: hormones related to the hypothalamic-pituitary-adrenal (HPA) axis (plasma cortisol, cortisol awakening response, diurnal cortisol slope, salivary cortisol at assessment), free thyroxine (F-T4), prolactin, or inflammatory markers. This study was designed as a pilot clinical trial in order to know the feasibility of the intervention and to calculate the effect sizes of different hormonal and inflammatory variables on cognition. This approach would allow the design of future larger clinical trials to test specific hypotheses generated with this study.
In this study, the investigators will be examining the effects of repetitive transcranial magnetic stimulation (rTMS) and intermittent theta burst stimulation (iTBS) on social cognitive impairments in individuals with schizophrenia spectrum disorders. Participants will be chosen by chance to receive either active rTMS stimulation, active iTBS stimulation, sham rTMS, or sham iTBS. The investigators predict that active 10Hz and iTBS stimulation will improve social cognitive impairments compared to sham stimulation. We aim to identify which type of active stimulation is most effective at inducing changes social cognition brain circuitry and secondarily which type of active stimulation is best tolerated and most effective at inducing changes in social cognitive performance.
The broad goals of our pilot study are to (1) determine whether psychodynamic psychotherapy for psychosis (PPfP), relative to treatment as usual (TaU), can maintain or augment clinical and functional benefits for patients who have achieved initial recovery in our coordinated specialty care (CSC) early psychosis treatment program; (2) to conduct novel empirical study of how various psychodynamic factors may inform candidate selection, mediate therapeutic effects, and influence relational aspects of the therapy; and (3) to conduct a detailed study of how features of therapist and patient speech and behavior influence therapeutic outcomes, therapeutic alliance alliance, and relational process. This registration focuses on the first goal.
These studies look to conduct efficient pilot testing of a novel intervention strategy for chronic psychotic disorders - Pharmacologic Augmentation of Cognitive Therapy (PACT) - via an experimental medicine approach. Antipsychotics are the major therapeutic tool for chronic psychotic disorders, including schizophrenia, but do not significantly alter their course or real-life impact. Specific cognitive therapies achieve modest symptom reduction and improved function and cognition in psychosis patients, including "bottom-up" sensory-based targeted cognitive training (TCT). While benefits of TCT are evident at the group level, almost half of all patients demonstrate little or no cognitive gains after 30-40 hours (h) of TCT. For patients and clinicians, the costs and logistical complexities associated with these time- and resource-intensive interventions can be prohibitive. We propose and will test a novel "augmentation strategy" for using medications to specifically enhance the benefits of TCT in schizophrenia.
