The goal of this observational study is to learn if there are potential digital and plasma-based biomarkers that could help detect, predict, and prognosticate delirium in older adult patients who are admitted to the intensive care unit (ICU). The main question DELTA aims to answer is: Can digital biometrics predict and detect delirium in older adult ICU patients? Do biomarkers of neurodegeneration fluctuate in ICU patients in such a way that delrium could potentially be predicted? Participants admitted o the ICU will wear a digital device to collect biometric data and will have serial plasma samples collected during ICU admission and patients will be also assessed for delirium daily by study staff.

Narcolepsy Type 1 (NT1) and Narcolepsy Type 2 (NT2) are rare conditions that make people feel very sleepy during the day (often referred to as excessive daytime sleepiness [EDS]). People living with these conditions might find it hard to stay alert and pay attention when they are at school, working, driving, or performing other daily activities. While all conditions result in feeling sleepy, there are some differences in other common symptoms: - NT1: People with NT1 often feel very tired during the day and experience cataplexy. Cataplexy is a sudden loss of muscle strength, which can cause someone to collapse or lose control of their muscles for a short time. This is often triggered by strong emotions, such as laughter or surprise. They may also have trouble sleeping well at night. - NT2: People with NT2 feel sleepy during the day, just like NT1, but they do not have cataplexy. Orexin is a protein in the brain that helps coordinate a system that plays an important role in helping people to stay awake during the daytime. Cleminorexton is designed to mimic the action of orexin. The purpose of this study is to see how safe and tolerable cleminorexton is in NT1 and NT2 and learn about what the drug does to the body. Another goal of the study is to see if cleminorexton can help people with NT1 and NT2 feel less sleepy and make other symptoms better.

H22 - Unconscious Mind Training and Memory Encoding Phase I The core problem this clinical trial, H22, seeks to address is the pervasive challenge of modifying deeply ingrained, often unconscious, unwanted behaviors within the general population. Many individuals struggle with habits or actions that negatively impact quality of life, productivity, or well-being, yet conventional methods often fall short due to the unconscious nature of these behaviors. Specifically, the trial aims to investigate the efficacy of H22, a novel intervention designed to engage and train the unconscious mind, in mitigating these unwanted behaviors. The central hypothesis guiding this research is that H22 training will empower volunteers to significantly reduce the frequency and intensity of identified unwanted behaviors.

Cancer treatment with immunotherapy is often associated with symptoms such as fatigue, pain, and emotional distress, which may affect patients' daily functioning and quality of life. Additional supportive care approaches are being studied to better understand their potential role in supporting these symptoms. The purpose of this study is to learn whether a biofield therapy, called Reiki may help to support adults with cancer who are receiving immunotherapy and currently struggling with fatigue. Reiki is a non-invasive complementary therapy delivered by a trained practitioner who places their hands lightly near the body. It is intended to promote relaxation and support general well-being. Reiki is used as a supportive practice and is not considered a medical treatment or replacement for standard care. The secondary goal of this study is to evaluate the feasibility of delivering Reiki in this clinical setting. This includes examining recruitment, retention, adherence to study procedures, and overall participant engagement. Lastly, the third aim is to explore participants' experiences with Reiki through guided interviews. Participants enrolled in this study will first be asked to participate in a one-hour, one-on-one interview about their experiences with cancer treatment, their symptoms, and their thoughts about integrative care practices such as Reiki. After the interview, they will be randomly assigned to one of two groups: Immediate Reiki Group: If participants are assigned to this group, they will receive six weekly, in-person 30-minute Usui Reiki sessions from a Reiki master at the Susan Samueli Integrative Health Institute. Before and after each session, participants will complete questionnaires about fatigue, pain, and stress. At the first and final sessions, a small blood sample will be collected to measure inflammatory biomarkers, and Electroencephalogram (EEG) hyperscanning will be conducted to measure brain activity and connectivity between the participant and the practitioner. Four weeks after the final session, they will complete the questionnaires again, followed by a short satisfaction survey about their experience. Waitlist Group: If they are assigned to the waitlist group, they will first complete a 6-week observation period that includes brief weekly fatigue questionnaires and two in-person 30-minute sessions with EEG measurements at Week 1 and Week 6. This will be followed by a 4-week period with no sessions, after which they will complete questionnaires about fatigue, pain, and psychological distress. Participants will then begin the same six weekly, in-person 30-minute sessions described above. As with the Immediate Group, they will complete questionnaires before and after each session. At the first and final sessions, a small blood sample will be collected and EEG hyperscanning will be conducted. At the end of the study, participants will also complete a short satisfaction survey about their experience. The investigators hypothesize that participants receiving Reiki will report improvements in symptoms and well-being compared to those not yet receiving Reiki, and that the intervention will be feasible to implement and acceptable to participants.

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. The first treatment is usually chemotherapy, given with another treatment that targets specific proteins on cancer cells. If the cancer gets worse, the next main treatment is usually a medicine called docetaxel. This treatment doesn't stop most people's cancer from getting worse for very long. Other treatments are needed to improve outcomes in people with NSCLC. Genes give your body instructions on how to make proteins. Proteins are needed to keep the body working properly. Many types of cancer are caused by changes in certain genes, making them faulty. Many people with NSCLC have a faulty KRAS gene in their tumor. One such change in the KRAS gene is called a G12D mutation. Researchers are looking for ways to stop the actions of abnormal proteins made from the KRAS G12D mutation. Setidegrasib (ASP3082) is thought to remove some of the abnormal proteins made from the faulty KRAS gene. Before setidegrasib can become available as a treatment, studies need to be done. This study is for people with NSCLC with a faulty KRAS gene in their tumor. In this study, some people will be given setidegrasib and some people will be given docetaxel. The main aims are to learn how long people who are given setidegrasib live with cancer without it getting worse, compared to people who are given docetaxel, and if they live for longer. Other aims are to check tumor response, symptoms, how the body processes setidegrasib, and its safety, compared with docetaxel. The main aims of study are to learn how long people who are given setidegrasib live with cancer without it getting worse, compared to people who are given docetaxel and if people who are given setidegrasib live for longer compared to people who are given docetaxel. People in this study will be adults with locally advanced, unresectable or metastatic non-small cell lung cancer (NSCLC) with the G12D mutation in their KRAS gene. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. They have had no more than 2 previous treatments for their cancer. The key reasons people cannot take part are if they have different faulty genes in their tumor which can be targeted with other treatments, have symptomatic or untreated cancers that have spread from the lung into the brain or nervous system, their cancer has spread to the thin tissue that covers the brain and spinal cord (leptomeningeal disease), or they have recently had other active cancers that required treatment. In this study, people will either receive setidegrasib or docetaxel. Whether people receive setidegrasib or docetaxel is decided by chance, not by the study doctor. Both study treatments are given slowly through a tube into a vein (infusion). People will continue to receive study treatment until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatment, they or the doctor decides the person should stop receiving study treatment, or sadly, they pass away. Some people on docetaxel may be able to switch to setidegrasib during the study if their cancer becomes worse. There will be safety checks at each visit, and the doctors will continue to check for medical problems and people's wellbeing throughout the study. People will continue to have scans of their tumor every 6 weeks for the first year, then every 9 weeks until their cancer becomes worse. After people's cancer becomes worse, clinic staff will telephone people every 12 weeks to check on their cancer.
