The study will adapt and deploy a digital Behavioral Activation app with mobile sensing, supported by health coaches, that encourages youth to engage in positive activities. The study has the potential to offer a low-cost and scalable behavioral intervention that may decrease risk of suicide among at-risk youth. This research will examine specifically whether an intervention involving an app called Vira, combined with health coaching (GET ActivE) can improve enjoyment for teens coping with depression. Research participants will be randomly assigned to one of two study intervention. One study intervention involves a) downloading an app called Vira and engaging by responding to a daily question, and b) participating in a conversation via text, phone, or messages through an appt with a health coach. The health coach will use the Vira app and principles from evidence-based therapy and behavior change to provide users with insights to sustain well-being and better manage risk factors for suicidal thoughts and behaviors such as depressed mood and behavioral withdrawal. The second study intervention involves downloading an app called EARS and responding to a daily question.

This phase III trial compares standard therapy given after surgery (adjuvant) to standard therapy given before and after surgery (perioperative) in treating patients with stage II-IIIB non-small cell lung cancer (NSCLC) that can be removed by surgery (resectable). The usual approach for patients with resectable NSCLC is chemotherapy and/or immunotherapy before surgery, after surgery, or both before and after surgery. This study is being done to find out which approach is better at treating patients with lung cancer. Treatment will be administered according to the current standard of care at the time of enrollment. Chemotherapy options may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, and vinorelbine at standard doses according to the treating physician. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by stopping cells from using folic acid to make deoxyribonucleic acid (DNA) and may kill tumor cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Other chemotherapy drugs, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading . Immunotherapy with monoclonal antibodies, such as nivolumab, pembrolizumab, and atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with chemotherapy and immunotherapy prior to surgery and continuing treatment after surgery may be a more effective treatment option than adjuvant therapy alone in patients with stage II-IIIB resectable NSCLC.

Research has shown a link between poor sleep health and late circadian timing with cardiometabolic health in adolescents with type 1 diabetes (T1D). Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in T1D, which begins as early as adolescence, and current therapies are limited. Therefore, this study plans to investigate whether cardiometabolic health can be improved with increased sleep duration and advanced circadian timing in adolescents with T1D with habitually insufficient sleep. To answer this question, investigators will study adolescents with T1D who get <7h sleep on school nights and measure changes in insulin sensitivity, glycemic control, and vascular function after one month of a sleep and circadian intervention (1+ hour longer time in bed each night plus evening melatonin and morning light therapy) compared to one month of typical sleep (usual school schedule).

This phase Ib/II trial evaluates the safety, optimal dose, and efficacy of the combination of epcoritamab and ibrutinib in treating patients with aggressive B-cell non-Hodgkin lymphoma that has come back (relapsed) or responded to previous treatment (refractory). Epcoritamab, a bispecific antibody, binds to two different types of receptors (proteins present on the cell surface) at the same time. The two receptors that epcoritamab binds to are called CD3 and CD20. CD3 is found on T cells, which are important cells of the immune system that help fight cancer and infections. CD20 is found on the surface of most types of aggressive B-cell non-Hodgkin lymphoma cells. By binding to both CD3 and CD20, epcoritamab brings the two cells close together so the T cells can fight and kill the lymphoma B cells. Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, binds to a protein on B cells, a type of white blood cell from which the lymphoma developed. By doing this it decreases the ability of the lymphoma B cells to survive and grow. Ibrutinib may also improve the health (or fitness) of T cells thus making epcoritamab safer and/or more effective.

Patients successfully resuscitated from sudden cardiac arrest are often comatose, having suffered a period of low blood flow and oxygen delivery to the brain. They are also at risk of suffering further brain injury during the immediate period after resuscitation, in which the brain's normal regulatory functions are impaired. To diagnose and treat secondary brain injury in comatose patients after cardiac arrest, doctors use a variety of neurological monitoring techniques. One of these methods involves measuring the oxygen saturation of blood going into and out of the brain to determine whether the brain is receiving and utilizing oxygen in an optimal manner. The oxygen saturation of blood exiting the brain is called the jugular venous oxygen saturation (SjO2). It is measured by inserting a catheter into the jugular vein in the neck and sampling blood as it exits the skull. The blood sample is sent to the hospital laboratory and the oxygen saturation is measured on a blood gas machine. This method of SjO2 measurement has limitations, particularly that blood must be taken out of the patient and sent to the lab for analysis, which can only be done feasibly every few hours. Special catheters exist that can measure the oxygen saturation of blood passing by the tip of the catheter inside the patient on a second-by-second basis, without needing to withdraw blood and send it to the laboratory. With such rapidly available data, doctors may be able to better diagnose and treat brain oxygen abnormalities in post cardiac arrest patients. In this study, the investigators plan to determine the accuracy of an existing, Food and Drug Administration (FDA)-cleared catheter capable of continuous, indwelling measurement of venous blood oxygen saturation for SjO2 monitoring in comatose patients early after cardiac arrest. The SjO2 measurements from the study catheter will be compared with standard SjO2 measurements made by withdrawing blood and analyzing it in the laboratory to determine if the new catheter is accurate. The investigators will also collect blood samples using the study catheter to measure levels of specific proteins that indicate damage to brain tissue. The study will enroll 25 participants admitted to the intensive care unit at one hospital cared for by a group of doctors that specialize in the neurological care of patients after cardiac arrest. The investigators hypothesize that the study catheter will accurately measure SjO2 compared to the standard laboratory method.
