The purpose of this study is to learn more about how cannabis use affects memory, thinking, and stress response in older adults, and how ovarian hormones affect them in older women. Participants will undergo a screening process over telehealth to confirm eligibility. There is a second telehealth visit to complete questionnaires, a cognitive testing battery, and a medical history. There is one visit in the clinic where participants will provide urine and saliva samples for drug and alcohol testing and a blood sample for a lipid testing, and complete additional cognitive tasks. They will then complete CREMA sessions (Cue Reactivity Ecologic Momentary Assessment) at home, two times a day for ten days. CREMA sessions include answering questions about marijuana use and sleep, and rating stress and craving.

This study will apply a novel imaging technique in patients with brain tumors to systematically evaluate the impact of various imaging parameters on image appearance, contrast, signal, and tumor sharpness, and to optimize the technique to maximize tumor visibility while minimizing scan time and image artifacts.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

You may qualify for this study if you have a history of atrial fibrillation (AF) and are currently taking an oral anticoagulant (a blood-thinning medication). You will be randomized to one of two groups: Control Group or Study Intervention Group.

If you are randomized to the Control group, you will be asked to stay on your previously prescribed oral anticoagulant. If you are randomized to the Study Intervention group, you will be asked to take the oral anticoagulant for 30 days only if a prolonged episode of AF is detected on an AF-sensing Apple smartwatch you will be provided.

This study is for patients who have newly diagnosed diagnosed BCR-ABL acute lymphoblastic leukemia (ALL). This study is being done to determine the effects (good or bad) of using the combination of a Tyrosine Kinase Inhibitor (TKI), steroids and blinatumomab versus treatment with steroids, Tyrosine Kinase Inhibitor (TKI) and chemotherapy. This investigational therapy will be added to what has traditionally been used to treat your specific sub-type of ALL. Studies are being done in ALL and other blood cancers with blinatumomab.

This study is for people with low-risk HER-2 positive breast cancer. The study is being done to see if treatment with HER2-targeted therapy without radiation therapy as good as the usual treatment of radiation and HER2-targeted therapy in patients who have had surgery, chemotherapy, and HER2-targeted therapy.

This is a randomized, double-blind, active- and placebo-controlled, parallel group, multicenter study to evaluate the efficacy and safety of induction and maintenance JNJ-78934804 therapy in participants 18 to 65 years of age (inclusive, at the time of consent), with moderately to severely active UC as determined by a modified Mayo score ≥5 and a final reported endoscopy subscore ≥2 obtained during the central review of the screening video endoscopy. Participants must also have demonstrated an inadequate initial response, loss of response, or intolerance to ≥1 approved ADT (advanced therapy inadequate responder [ADT-IR]). Overall, the study will evaluate 48 weeks of therapy with JNJ-7893480. The primary objective of the study is to evaluate the efficacy of JNJ-78934804 at Week 48
compared with each monotherapy (guselkumab alone and golimumab alone).

This study is for patients with acute leukemia or myelodysplastic syndrome (MDS). This study is being done to help understand whether a haplo related donor or a MUD HCT for people with acute leukemia or MDS is better or if there is no difference at all.

Apathy is a common set of symptoms seen in many people following a stroke. Apathy occurs when a person has lost motivation, becomes withdrawn, and stops doing things that used to be important to them. Apathy has a large negative impact on a person's quality of life, and can also have a large impact the people who take care of individuals with apathy. There are currently no FDA-approved treatments to help with apathy, and other services like therapy may be difficult to access for people who have had a stroke. To address this problem, we are conducting a study to find out if a form of treatment called repetitive transcranial magnetic stimulation (rTMS) can be safe and helpful for people struggling with apathy after a stroke. Our study will apply a new form of rTMS which can be delivered quickly to a part of the brain called the medial prefrontal cortex (mPFC). Our study will help establish whether this treatment is safe, comfortable, and effective for people with apathy after a stroke, and will help researchers develop new forms of treatment.
