TraumaAnxiety2 moreThe purpose of this study is to test the effectiveness of a universal, digital, single-session intervention for youth mental health, functioning, and well-being. The investigators will be providing access to a brief online program (Project SOLVE) for students as part of the school curriculum. Ukrainian students living in Poland will be randomly assigned to receive Project SOLVE either immediately or after 3 months.

The investigators would like to evaluate the effectiveness of this intervention in improving students' mental health and well-being.

A Study of the Efficacy of Fecal Microbiota Transplantation(FMT) in the Treatment of Depression...
DepressionPatients with depression were enrolled and randomly divided into two groups, namely FMT combined with antidepressant group and Antidepressant alone group.The former received FMT capsules and antidepressants, and the latter received oral placebo and antidepressants for an 8-week intervention.Before and after intervention, venous blood samples were collected from patients for routine tests such as liver and kidney function to judge the safety of treatment. At the same time, psychological scales were used to evaluate the improvement of patients' depressive symptoms, so as to judge the efficacy and safety of FMT combined with antidepressants.

Ketogenic Diet for Treatment-Resistant Depression: Dietary Interventions for MEntal Health Study...
Treatment Resistant DepressionDepression3 moreDepression is a debilitating chronic illness affecting 1 in 6 UK adults at any one time. Antidepressants and psychological therapy are the main treatments, but some people do not respond to these. Neurons and signals in the brain are greatly disrupted in people with severe depression. A ketogenic diet, a high-fat and very low-carbohydrate diet, supplies a form of energy that appears to help brain cells communicate and may improve the treatment of depression. Our goal is to find out whether a ketogenic diet could be an additional effective treatment for patients with depression for which antidepressants do not work. Using social media advertising, we aim to recruit 100 patients, ages 18-65, who have previously tried at least two different antidepressant medications within the current depressive episode. Enrolment, consent, and data collection will be collected online using self-report questionnaires. Participants will be allocated by minimisation 1:1 to the KD group or control group based on depressive severity (moderately severe vs. severe) and body mass index (<30kg/m2 vs. 30+ kg/m2). The intervention group will receive 6-weeks of prepared ketogenic diet meals (3 meals with snacks per day) and weekly ketogenic diet-focused nutrition counselling. The control group will be asked to follow a diet to reduce their saturated fat intake and increase vegetable consumption by one portion a day. The control group will receive vouchers to assist with purchases and will be provided with weekly nutritional counselling. Existing treatment for depression will remain in both groups. The primary outcome is the change in depression symptoms at six weeks. All participants will complete assessments of their depression and anxiety intensity every two weeks, starting before treatment to post-intervention (week 6), and again at week 12. We will also assess participants' ability to experience pleasure, quality of life, ability to socialise and work, cognitive processing, morning cortisol, and gut microbiome. At all stages of the study, several members of the public with lived experience of depression will advise the research team to take into account the needs and views of patients. Our study will provide evidence of whether following a ketogenic diet leads to a short-term improvement in depression in people whose depression cannot be relieved by antidepressants. Our research may pave the way for longer trials and eventually lead to new ways of treating depression.

Effectiveness of a Guided Mobile App Intervention for Depression and Anxiety in University Students...
Depressive SymptomsAnxietyBackground: Symptoms of depression and anxiety are prevalent among Spanish university students. Minimally guided online interventions have shown promise in reducing symptomatology and preventing increased mental distress. There is a need to evaluate the effectiveness of guided preventive mental health interventions for depression and anxiety in university students. Methods: two-arm multicenter randomized controlled trial (RCT), addressed to undergraduate students from 6 public universities with symptoms of depression and/or anxiety. Students will be evaluated through an online survey assessing mental health problems, use of mental health services, sociodemographic variables, self-perceived health, childhood and adolescent adversities, recent stressful events, social networks, personality and university experiences. A total of 600 students will be randomly assigned to: intervention group (guided E-health prevention intervention) or control group (treatment as usual with self-monitoring). The intervention, in app format, is based on principles of cognitive behavioral therapy, includes weekly feedback based on content and participation from a psychologist and self-monitoring. Assessments will take place post-intervention (up to 6 weeks), at 6 months and 12 months after randomization. The primary outcome will be the reduction of depressive or anxiety symptoms post-intervention, assessed with the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-Anxiety and Depression Scale (PHQ-ADS). Secondary outcomes of the RCT will be mental wellbeing, academic stress, comorbid symptoms, and adherence. Analyses will be conducted on an intention-to-treat and per protocol basis. Discussion: The results of the PROMES-U RCT will provide valuable information on a guided preventive online intervention that could be delivered in the campus context. In addition, results will provide information on the positive impact of the intervention on other relevant factors involved in mental health among university students.
