Eating Disorder

Researchers are conducting the GENESIS clinical study to map the HLA genomic region in the Greek population and explore its possible links with various underlying diseases. This non-interventional, multicenter study aims to provide a pilot map of genetic variation in HLA that may be useful in medical research and clinical applications related to selected diseases. The study plans to include 12,000 participants over a total duration of 36 months. Each participant will attend one visit at a participating site during which they will provide demographic data, lifestyle information such as smoking and alcohol use, blood pressure measurements, details on diagnosed diseases and treatments, and recent laboratory test results if available. Buccal swab samples will be collected from each participant to extract DNA for HLA genotyping analysis. Selected samples will undergo further whole genome sequencing to investigate associations with autoimmune diseases. Participants will receive a personalized ancestry report after analysis completion. During the study visit, data collection includes demographic and health information, as well as laboratory and clinical test results from the past year. The genetic material from buccal swabs will be stored and processed for genetic analysis. Researchers will measure allele frequency of HLA alleles in the Greek population and assess the prevalence and risk associations of selected HLA-related diseases. The study's total duration is 36 months with results available at the end of this period.

Researchers are evaluating the feasibility and preliminary clinical outcomes of a personalized digital treatment designed for adolescents with eating disorders aged 15 to 18 years. The study aims to understand who benefits from this digital approach, how acceptable and credible it is to participants, and the cost-effectiveness of delivering such treatment in routine child and adolescent psychiatric outpatient care. The intervention includes a therapist-guided digital program consisting of 8 modules delivered over 10 weeks, with weekly therapist contact. Participants will complete self-report questionnaires before, during, and after the treatment, as well as at 3- and 6-month follow-ups. The study also involves semi-structured phone interviews with some participants to explore their experiences with the treatment. Participants will be asked to complete various validated questionnaires assessing eating disorder symptoms, general psychopathology, quality of life, and treatment satisfaction throughout the study period. Adherence to the treatment and participant experiences will be monitored, along with health and social outcomes such as school attendance and emotional regulation. Data collection occurs online, and the total follow-up extends to six months after treatment completion.

Suicide is the second leading cause of death among youth, and rates in the US are rising despite prevention efforts. Researchers are evaluating a digital platform called Vira to improve how care is delivered to adolescents at high risk for suicide. This platform aims to use smartphone data and secure communication tools to better understand and manage risk factors like psychological distress, anhedonia, behavioral withdrawal, and sleep problems in young people receiving intensive outpatient treatment. The study compares two groups of adolescent patients aged 13 to 18 years old who are in an intensive outpatient Dialectical Behavior Therapy (DBT) program. One group uses the Vira platform, which collects data passively from smartphone sensors about activity, sleep, mobility, and mood-related language. Vira also prompts daily check-ins and supports practitioners with reminders to encourage behavior changes. The other group receives the usual treatment with the addition of a passive monitoring app called EARS. Participants will use their assigned app during their intensive outpatient treatment. Researchers will assess outcomes using tools like the Columbia Suicide Severity Rating Scale and Scale for Suicidal Ideation over six months. Other measures include anxiety, risky behaviors, sleep quality, mood, and pleasure scales at three and six months. The study monitors clinical outcomes to determine if the digital platform enhances care for youth at risk of suicide.

Researchers are studying Severe and Enduring Eating Disorders (SEED), which are long-lasting eating disorders affecting adolescents and adults. The study aims to understand the clinical, psychological, and biological factors that contribute to the development and persistence of SEED. It follows two groups of patients, one aged 14-17 and one aged 18 and older, to observe changes and impacts over time. Participants will be followed at multiple points: at the start (baseline), after treatment, two years later, and then at five, 10, and 20 years after baseline. During these times, they will undergo physical exams, provide blood samples, participate in interviews, and complete questionnaires. Caregivers of minors will also complete questionnaires. The study collects extensive data on psychiatric symptoms, personality, emotion regulation, loneliness, and inflammatory markers. Throughout the study, participants will be assessed with various interviews and questionnaires to measure eating disorder symptoms, psychosocial functioning, quality of life, and biological markers. Weekly weight checks occur during treatment and follow-up. Researchers will analyze how different factors influence the course of the disorder and treatment outcomes. The study may last up to 20 years for some participants and includes regular digital questionnaire responses and registry data reviews.

Researchers are evaluating the effects of a smartphone-based Healthy Lifestyle (HLS) intervention on the mental and physical health of firefighters in Tainan, Taiwan. This cluster randomized controlled trial aims to determine if the Traditional Chinese version of the HLS mobile app can improve firefighters' health compared to usual care. The study also seeks to find out whether the intervention can promote a healthier lifestyle and reduce the risk of chronic non-communicable diseases among firefighters. Participants will be randomly assigned to either the intervention group, which uses the Traditional Chinese HLS mobile app designed specifically for firefighters, or the control group, which receives usual care. The intervention period lasts from 3 to 6 months, during which firefighters in the intervention group will use the app to support healthier behaviors. The control group will continue with their standard practices without the app. Throughout the study, firefighters will undergo health and fitness assessments at the start and again 3 to 6 months after the intervention begins. Measurements include blood pressure, depressive symptoms, PTSD symptoms, body mass index, smoking habits, diet patterns, physical activity levels, sitting time, sleep duration and napping frequency, glycated hemoglobin, lipid profiles, C-reactive protein, and physical performance. The study will monitor these outcomes to assess changes in mental and physical health. Safety and progress will be observed through these regular evaluations during the study period.

Researchers are studying the effects of a low-protein diet on cancer patients receiving immunotherapy treatments. The study aims to see if reducing protein intake can change the tumor environment and boost the body's immune response, potentially enhancing the effects of immune checkpoint inhibitors. This is a randomized, open-label study conducted at a single center to explore the feasibility of this dietary approach. Participants will be randomly assigned to one of two groups: one receiving immunotherapy plus a control diet containing about 20% protein, and the other receiving immunotherapy combined with a low-protein diet containing 10% protein. The study intervention lasts for 4 months, during which the dietary impact on immune response and treatment effects will be evaluated. Throughout the 4-month study period, participants will be monitored for their ability to follow the dietary plan and for any changes in immune response to immunotherapy. Researchers will assess safety, tolerability, clinical efficacy using RECIST v1.1 criteria, and enrollment and drop-out rates. Laboratory tests and imaging scans will also be conducted to evaluate disease progression and treatment impact.

Researchers are studying the effects of intermittent caloric restriction combined with a plant-based diet in cancer patients receiving chemotherapy. This pilot trial aims to assess whether this dietary approach is feasible and safe alongside standard chemotherapy, and whether it may reduce side effects while potentially enhancing the chemotherapy's antitumor effects. Participants will follow a protocol involving alternate-day intermittent caloric restriction along with a plant-based protein diet during their chemotherapy treatment. The study evaluates how this combined dietary intervention interacts with standard chemotherapy regimens over the course of treatment. During the study, participants will be monitored for adherence to the dietary plan and chemotherapy treatment. Researchers will assess feasibility over 12 months, including safety and preliminary evidence of clinical efficacy. Evaluations may include health assessments, laboratory tests, and monitoring of side effects throughout the study period.

Researchers are evaluating whether teaching people personalized versus standardized emotion regulation skills can better reduce daily negative emotions. The study also aims to see if matching participants to their predicted best skill training is feasible and helpful. This research may reveal how emotion regulation treatments impact emotional health and help develop personalized, evidence-based, and scalable interventions. Participants will be randomly assigned to learn one of three emotion regulation skills—cognitive restructuring, opposite to emotion action, or mindfulness—that matches their personal strengths, or to learn all three skills through interactive videos with surveys to practice and check understanding. These training conditions are designed to compare focused versus broad skill coverage. During the study, participants will report their emotions multiple times daily for 42 days, using the Positive and Negative Affect Schedule-Short Form. They will also complete assessments every two weeks for six weeks, measuring depression, anxiety, personality traits, responses to emotions, and breath-counting tasks. Researchers will monitor changes in emotion regulation effectiveness and emotional experiences to understand the impact of the training.

Researchers are studying anorexia nervosa (AN), a serious psychiatric disorder with the highest mortality rate, focusing on how caloric and non-caloric food intake affects stress responses and brain activity. The study compares female AN patients aged 13 to 18 who are newly diagnosed and treatment-nave, with healthy volunteers matched by age, sex, and education. The aim is to understand biological and psychological responses linked to eating in AN and to explore brain network changes related to calorie intake through neuroendocrine and psychological measures. Participants will be randomly assigned to consume one of two jellies: a 400-calorie mixture or a calorie-free mixture, both prepared to look and taste similar. AN patients will be admitted overnight to ensure a 12-hour fast before the study day. After psychiatric assessments and initial brain scans, participants will consume the jelly within 15 minutes, and their intake amount will be recorded. A second brain scan one hour later will assess brain network changes. Three hours later, participants will be offered a standard oatmeal meal with calories, allowed up to 500 kcal, and the amount consumed will also be measured. Throughout the study, participants will undergo psychiatric evaluations, blood sampling for hormones and biochemical markers, blood pressure and pulse monitoring, and brain MRI scans before and after meal intake. Self-report scales will assess hunger, anxiety, mood, and eating-related fears. Researchers will compare physiological, psychological, and behavioral responses before and after meals between AN patients who receive calories, those who do not, and matched healthy controls. The study will last until the end of 2026 with ongoing monitoring and data analysis.

Researchers are evaluating the feasibility and usability of a digital intervention called ChangeBite for adults with obesity and binge eating behavior. This open-label, non-randomized pilot study plans to include about 30 participants. The study aims to understand how well participants can engage with this self-guided mobile program that combines evidence-based treatments for obesity and binge eating. All participants will receive the ChangeBite intervention delivered through a smartphone app. The program integrates behavioral weight loss treatment and cognitive behavioral therapies into a personalized, self-guided experience using an artificial conversational agent and adaptive interventions. The study includes a baseline period followed by assessments at 12 and 24 weeks, during which participants will use the app and attend follow-up video calls. Participants will complete self-report scales and semi-structured interviews conducted via video call. The study will track app use frequency and duration through software analytics. Weekly body weight will be recorded by participants submitting timestamped pictures of their scale readings, allowing calculation of Body Mass Index. The research team will measure binge eating episodes and weight changes over three months to assess feasibility and acceptability of the intervention.
