Heart Rate Variability Biofeedback for Anxiety in Autistic Youth

Heart rate variability biofeedback (HRVB) is a breathing-based intervention that reduces anxiety in a range of populations. Second-generation wearable HRVB devices not only deliver scheduled biofeedback practice sessions but also allow patients to practice HRVB in-the-moment when it is needed most. This study is testing the acceptability, feasibility, and preliminary efficacy of second-generation, ambulatory HRVB for the treatment of anxiety in autistic youth.

Cognitive Dysfunction in Chronic and Persistent Immune Thrombocytopenia

Individuals with immune thrombocytopenia (ITP) frequently report difficulties with attention and memory. The main question this study seeks to answer is: Do patients with ITP have evidence of cognitive impairment as detected by a cognitive function test battery? To address this issue, participants will take a cognitive function test and complete surveys on quality of life, fatigue, depression, and cognitive symptoms. The primary aim of the study is to evaluate for the presence and extent of cognitive impairment in patients with ITP. The study will also assess whether cognitive impairment in ITP is associated with patient-reported impacts on quality of life, fatigue, mood, and cognitive symptoms as well as clinical characteristics such as ITP disease and treatment history.

Testing the mHealth App Intervention for Nondaily Smokers "SiS4"

The goal of this project is to test if a new behavioral treatment for people who smoke nondaily and wish to quit works. The new treatment is a smartphone app that engages users in positive psychology exercises and gives them tested tools for quitting smoking. The positive psychology exercises help users maintain their positive emotions while they quit smoking. This app has been developed with and for people who smoke nondaily through several steps of development. The main questions it aims to answer are: * Does the smoking cessation app (SiS4) help people who smoke nondaily quit smoking? * How do people's attitudes towards smoking, their smoking urges, and their mental well-being shift when using the SiS4 app? Researchers will compare the new app to an existing app that was developed for people who smoke daily to see if the new app works better to help people who smoke nondaily quit smoking. Participants will: 1. Use a smartphone app every day for 7 weeks 2. Complete online surveys about their smoking, attitudes about smoking, withdrawal symptoms and smoking urges, app use, and mental well-being at enrollment as well as 2 weeks, 6 weeks, 3 months, 6 months and 12 months after the initially chosen quit date. If the SiS4 app works well, it would be the first evidence-based quit-smoking treatment for people who smoke nondaily.

Time Restricted Eating (TRE) in Bipolar Disorder

This is a randomized controlled trial investigating the effects of an 8-TRE intervention compared to a wait list (control) on metabolic health and body composition in people diagnosed with BD and who are currently obese and at least mildly depressed. Following a 1-week baseline assessment, participants will be randomized to either a TRE or the wait list (1-to-1 ratio) for 8 weeks. At baseline, Week 8 (post treatment), and Week 20 (follow-up), investigators will assess daily eating patterns for one week, followed by collection of fasting lipids, body weight and vital signs. At Week 4 (i.e., mid-treatment), the investigators will assess self-reported outcomes only. Participants assigned to the wait list condition will have the option of receiving the TRE intervention after 20 weeks.

Investigating Exercise in Myotonic Dystrophy Type 2 (DM2)

An exercise regimen (PRIME: Proximal Resistance In-House Movement Exercise) has been designed for patients with myotonic dystrophy type 2 (DM2). The hypothesis is that this patient-friendly physical therapist (PT)-guided exercise program associates with improved functional capacity and muscle composition in DM2 in this two-period two-sequence cross-over study. Thus, participant will be randomized to one of the three possible groups. Participants in GROUP A will perform exercise routine virtually under the direct supervision of a physical therapist once a week and another session on their own for the first three months, then they will continue with same exercise routine at home for the last 3 months on their own. Participants in GROUP B will perform exercise routine virtually under the direct supervision of a physical therapist twice a week for the first three months, then they will continue with same exercise routine at home for the last 3 months on their own. Participants in GROUP C will perform exercise routine on their own during the first 3 months, then they will perform exercise routine virtually under the direct supervision of a physical therapist. Each group will include around 8 participants. Duration of the study is 6 months. In addition to exercise sessions, participants will have evaluation of their strength, motor function and muscle composition at three time points: initiation, 3 months and completion of the study at 6 months. Muscle composition will be assessed by electrical impedance myography which is a portable, non-invasive, painless and non-radiation tool that applies a weak high multifrequency electrical current to the examined muscle and allows to obtain information about its composition.

Augmenting Clinical Workflow With a Structured Chatbot for Patient History Collection and Diagnostic Support

Doctors spend much of each visit collecting the patient's medical history, and incomplete histories can delay diagnosis. This study tests an AI chatbot that interviews patients before their appointment and produces a structured summary of their history for the doctor. Adult patients at the first study site, a university gynecology outpatient clinic in Germany, answer the chatbot's questions on a tablet before the doctor visit. The doctor then takes the history and examines the patient as usual, without seeing the chatbot's output. Only after the doctor has finished planning care does the doctor review the chatbot's summary and rate its usefulness and accuracy. The chatbot does not change patient care. Patients also rate the ease of use and acceptability of the chatbot. The investigators will report how useful doctors find the summaries, how complete and correct the summaries are, and how patients experience the tool.
