Clinical trials

Intrusive re-experiencing is a hallmark of PTSD. The study applies ecological momentary assessment (EMA) of participants' trauma memories (active group) vs. EMA of a neutral memory (control group) to test whether the active intervention can reduce intrusive symptoms severity and overal PTSD symptom severity in general.

This study examines whether a computerized attention-training intervention called attention bias modification (ABM) can reduce symptoms of social anxiety disorder (SAD) in adults, and whether symptom improvement is specifically related to changes in attentional processing or to nonspecific factors such as expectancy and placebo effects.

The goal of this clinical trial is to learn if the Ultra-Brief Interpersonal Psychotherapy for Adolescents with Suicidal Ideation (IPT-A-SCI) works to reduce suicidal thoughts and behaviors in children and adolescents. The study will also examine whether treatment effects continue after treatment ends and whether some participants benefit more from the intervention than others. The main questions it aims to answer are: Does IPT-A-SCI reduce suicidal thoughts and behaviors in children and adolescents? Do the effects of IPT-A-SCI continue three months after treatment ends? Do some children and adolescents benefit more from IPT-A-SCI than others? Participants will: Receive IPT-A-SCI treatment consisting of five weekly sessions Complete questionnaires before treatment, during treatment, at the end of treatment, and three months after treatment ends Have their parents complete questionnaires at the same time points

This prospective observational study aims to characterize within-individual variability in resting metabolic rate (RMR) over a 12-week period using high-frequency repeated measurements under standardized conditions. Participants will undergo RMR assessments three times per week using whole-room indirect calorimetry. The study will quantify the magnitude of physiological variability in RMR, distinguish true biological variation from measurement error, and estimate the minimal detectable change required to identify meaningful metabolic adaptations.

Weight loss induced by hypocaloric dietary interventions is commonly accompanied by reductions in resting metabolic rate (RMR), a phenomenon often described as metabolic adaptation. The magnitude of this decline varies substantially between individuals and may depend not only on the amount of weight lost but also on the composition of weight loss, particularly the relative contributions of fat mass and fat-free mass. This prospective interventional study will investigate whether changes in body composition during a hypocaloric dietary intervention are associated with changes in RMR and metabolic adaptation. Approximately 150 adults with overweight or obesity will participate in a structured dietary program designed to induce moderate energy restriction. Body composition and resting metabolic rate will be assessed before and after the intervention to evaluate associations between fat mass loss, fat-free mass loss, and metabolic responses to weight reduction.

This study aims to characterize how individuals differ in their metabolic response to food intake, specifically focusing on early diet-induced thermogenesis (DIT). DIT refers to the increase in energy expenditure that occurs after eating and reflects the body's metabolic response to processing nutrients. Healthy adult participants will complete a single laboratory visit under standardized conditions. Resting metabolic rate will first be measured, followed by consumption of a standardized liquid meal (550 kcal). Energy expenditure will then be continuously monitored for 3 hours using indirect calorimetry. The primary objective is to quantify inter-individual variability in early postprandial thermogenesis. Rather than estimating total daily energy expenditure, this study focuses on the early metabolic response following meal ingestion. Findings will improve understanding of differences in metabolic efficiency between individuals and support future research in metabolism and personalized nutrition.

This study examines whether resting metabolic rate (RMR)-the amount of energy the body uses at rest-is similar between biological parents and their adult children (aged 18 years and older). RMR is the largest component of daily energy expenditure and plays an important role in body weight regulation and overall metabolic health. Participants from the same family will undergo a single testing session in a metabolic laboratory. RMR will be measured using indirect calorimetry under standardized conditions, along with body composition assessment and basic health information. The primary goal is to determine whether RMR is correlated within families. The study will also assess whether these similarities remain after accounting for differences in body composition, age, and sex. This observational study will help improve understanding of how metabolism varies between individuals and the extent to which these differences may be influenced by familial or inherited factors. Findings may contribute to future research on personalized nutrition, obesity risk, and metabolic health.

This randomized controlled trial will examine the effects of within-day protein distribution and leucine supplementation on body composition, physical performance, and biomarkers of muscle damage in tactical athletes during an 8-week intensive training program. Sixty-nine healthy male participants (18-35 years) enrolled in a Ministry of Defense training course will be randomly assigned to one of three iso-caloric dietary groups providing 1.6 g/kg/day of protein: (1) evenly distributed protein across three meals (EVEN), (2) a 16-hour daily protein fasting pattern with protein concentrated at lunch and dinner (FAST), or (3) the same fasting pattern with 5 g leucine supplementation at breakfast (FAST-RESCUE). Primary outcomes include changes in lean body mass. Secondary outcomes include strength, anaerobic performance, and biochemical markers of muscle damage, including urinary titin N-terminal fragment (UTF). Assessments will be conducted at baseline, Week 5, and Week 8.

The goal of this clinical trial is to evaluate the efficacy of adjunctive application of diode laser to mechanical, non-surgical root surface debridement in patients attending periodontal office. The main question it aims to answer is: To compare the clinical effectiveness of adjunctive application of a 940-nm diode laser with root surface debridement to the effectiveness of root surface debridement alone. This study is a split-mouth design, where each quadrant will be randomly allocated to one of the following groups: Control group (root surface debridement - RsD): scaling and root planing alone. Laser group (RsD + laser): scaling and root planing with adjunctive diode laser therapy Quadrants will be randomly allocated to the treatment groups

The goal of this clinical trial is to examine the effectiveness of Adaptive Karate Training (AKT) in improving self-regulation and daily function in children with ADHD, exploring the underlying mechanisms. The main questions it aims to answer are: 1. Is the AKT more effective than no karate training in enhancing functional performance, self-regulation and school QoL? 2. Are poorer executive functions, emotional regulation, and sensory processing associated with higher gains? Researchers will compare two sequences: (1) A group receiving AKT followed by a no-intervention period; (2) A group receiving no intervention, followed by the AKT intervention, to see if differences are observed between intervention and no-intervention periods, both between groups and within participants over time. Participants will engage in AKT sessions twice a week, each session lasting 60 minutes, over a period of two months.

The main objective of this randomized controlled trial is to evaluate whether a gaze-contingent feedback task using negative reinforcement can serve as an effective attention-modification procedure and contribute to the treatment of Major Depressive Disorder (MDD).

This randomized controlled trial will test the efficacy of CBT-I intervention for school-aged children (7-11 years old) with insomnia. The trial will focus on the role of sleep restriction therapy in treatment. Children will be randomized to one of three groups: (1) CBT-I; (2) CBT-I without SRT; or (3) a waitlist control group. Assessments will occur at baseline, mid-treatment, post-treatment, and a 3-month follow up. Some measures (e.g., child motivation) will also be assessed after each therapy session. Insomnia and sleep-wake patterns will be assessed objectively using actigraphy, and subjectively using sleep diaries, a clinical diagnostic interview, and questionnaires. Parent and child questionnaires will be administered to assess moderators and mediators of treatment outcomes.

The goal of this clinical trial is to learn if adding Shiatsu therapy to standard treatment can improve quality of life in children and adolescents with chronic pain that is not caused by inflammation. The main question it aims to answer is: Does Shiatsu therapy help improve the quality of life in children with long-lasting pain? All participants will continue their regular treatment and will also: * Receive a 30-minute Shiatsu session once a week for six weeks * Complete questionnaires about their quality of life and family impact before, during, and after the treatment period The study includes about 40 participants between the ages of 10 and 18, who are already being followed at the pediatric pain and rheumatology clinics at Tel Aviv Sourasky Medical Center.

This RCT investigates whether Cognitive Processing Therapy, a first line treatment for PTSD, can be enhanced by the use of the odor molecule Hexadecenal (HEX). HEX is secreted from body odor and has been shown to promotes psychological well-being and positive social interaction. For the active group Hex will be diffused in the treatment room during all treatment sessions. For the control group a vehicle placebo molecule will be diffused. Both therapists and patients will be blind to study condition.

This clinical study will examine the efficacy of a novel intervention aimed at improving Regulatory Selection Flexibility and PTSD symptoms among adult individuals with PTSD symptoms, compared to a tight active control group.

Military service and reserve duty in combat units entails exposure to traumatic events that require mental adjustment. In light of the results of controlled studies that proved the effectiveness an response-time based mechanized training protocol in reducing risk for post-trauma symptoms in deployed combat soldiers, the Israeli Defense Forces decided at the beginning of the Iron Swords War to implement an internet-based App of the intervention. Soldiers and combat reservists were invited to use the Combat Attention App. The purpose of this study is to examine the effectiveness of the Combat Attention App in relation to a control group of soldiers who did not use the App in reducing risk for post-traumatic stress symptoms of deployed soldiers.

The goal of this clinical trial is to learn if non-invasive neurostimulation of memory-related brain areas works to treat intrusive memory symptoms in adults patients with posttraumatic stress disorder (PTSD). It will also learn about the effect of this neuromodulation procedure on reorganization of memory-related brain networks. The main questions it aims to answer are: Does neuromodulation lower the number of times and the emotional severity participants intrusive memories? Does neuromodulation reduces the overall severity of PTSD? Researchers will compare neuromodulation targeting the hippocampus (a memory-related brain structure) to a control stimulation in an area not related to memory processes to see if hippocampus neuromodulation works to treat intrusive trauma memories and PTSD. Participants will: 1. Undergo magnetic resonance imaging (MRI) scans before and after neuromodulation to: a) determine a personalized neuromodulation target; and b) to measure changes in brain function from before to after treatment. 2. Receive hippocampus neuromodulation or a control neuromodulation once a week for 5 weeks. Keep a daily diary of their symptoms and the number of times they experience intrusive trauma memories.

The study has three main phases. The first phase included A. Adjustment of research tools. Phase B. will examine the efficacy of the cultural intervention. Phase C. Follow-up study will be conducted after three, six, and nine months.

The period of pregnancy, childbirth, and the postpartum phase significantly impacts the mental health of women and their families. Mental health is crucial for overall well-being, quality of life, and is associated with healthcare costs. Therefore, promoting mental health should be a top priority in public health and health promotion efforts. The Inquiry-Based Stress Reduction (IBSR) intervention, developed by Byron Katie ("The Work"), enables participants to identify and question the stressful thoughts that cause their suffering. The core of IBSR involves a contemplative "inquiry" process and a "turnaround," which is a method of experiencing the opposite of what the participant believes. This process equips individuals with skills for self-inquiry and management of stressful thoughts that can be easily integrated into daily life. Based on previous research, we hypothesize that the IBSR intervention can improve postpartum mothers' mental health.
