Digital Tomosynthesis Mammography and Digital Mammography in Screening Patients for Breast Cancer
This randomized phase III trial studies digital tomosynthesis mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis mammography may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.

• Women of childbearing potential must not be known to be pregnant or lactating
• Patients must be scheduled for, or have intent to schedule, a screening mammogram
• Patients must be able to tolerate digital breast tomosynthesis and full-field digital mammographic imaging required by protocol.
• Patients must be willing and able to provide a written informed consent
• Patients must not have symptoms or signs of benign or malignant breast disease (eg, nipple discharge, breast lump) warranting a diagnostic rather than a screening mammogram, and/or other imaging studies (eg, sonogram); patients with breast pain are eligible as long as other criteria are met
• Patients must not have had a screening mammogram within the last 11 months prior to date of randomization
• Patients must not have previous personal history of breast cancer including ductal carcinoma in situ
• Patients must not have breast enhancements (e.g., implants or injections)
• ANNUAL SCREENING REGIMEN ELIGIBILITY CHECK
• To be eligible for inclusion in the annual screening regimen one of the following three conditions must be met in addition to the eligibility criteria above:
• Patients are pre-menopausal; OR
• Post-menopausal aged 45-69 with any of the following three risks factors:
• Dense breasts (BIRADS density categories c-heterogeneously dense or d-extremely dense), or
• Family history of breast cancer (first degree relative with breast cancer), or, positive genetic testing for any deleterious genes that indicate an increased risk for breast cancer, or
• Currently on hormone therapy; OR
• Post-menopausal ages 70-74 with either of the following two risk factors:
• Dense breasts (BIRADS density categories c-heterogeneously dense or d-extremely dense), or
• Currently on hormone therapy
• Postmenopausal women are defined as those with their last menstrual period more than 12 months prior to study entry; for the purpose of defining menopausal status for women who have had surgical cessation of their periods, women who no longer have menses due to hysterectomy and oophorectomy will be considered postmenopausal; women who no longer have menses due to hysterectomy without oophorectomy will be considered premenopausal until age 52 and postmenopausal thereafter
• All other postmenopausal women are eligible for inclusion in the biennial screening regimen
• For those women who cannot be assigned to annual or biennial screening at the time of study entry and randomization because they are postmenopausal, have no family history or known deleterious breast cancer mutation, are not on hormone therapy AND have not had a prior mammogram, breast density will be determined by the radiologist?s recording of it at the time of interpretation of the first study screening examination, either DM or TM; for those who are randomized to TM, radiologists will assign BI-RADS density through review of the DM or synthetic DM portion of the TM examination; such women cannot be part of the planned stratification by screening frequency and are expected to represent far less than 1% of the Tomosynthesis Mammographic Imaging Screening Trial (TMIST) population
• Breast density will be determined by prior mammography reports, when available; all other risk factors used to determine patient eligibility for annual or biennial screening will be determined by subject self-report
Semaglutide Effects on Heart Disease and Stroke in Patients With Overweight or Obesity (SELECT)
The researchers are doing the study to see if semaglutide may reduce the risk of having cardiovascular events in patients with overweight or obesity and with prior cardiovascular disease. The participant will either get semaglutide (active medicine) or placebo ("dummy" medicine). Which treatment the participants get is decided by chance. The participant's chance of getting semaglutide or placebo is the same. The participant will get the study medicine in a pen. The participants will need to use the pen to inject the study medicine in a skinfold once a week. The study will last for about 2.5 to 5 years. Participants will have up to 25 clinic visits with the study doctor.

Exploring the Effects of Corticosteroids on the Human Hippocampus
Chronic corticosteroid (CS) exposure is associated with changes in memory and the hippocampus in both humans and in animal models. The hippocampus has a high concentration of glucocorticoid receptors (GCRs), and the pre-clinical literature demonstrates shortening of apical dendrites in the CA3 region of the hippocampus and decreased neurogenesis in the dentate gyrus (DG) following CS administration. In humans, both stress and CS exposure are associated with a decline in declarative memory performance (a process mediated by the hippocampus). Impairment in declarative memory and hippocampal atrophy are reported in patients with excessive CS release due to Cushing's disease, and, by our group, in patients receiving prescription CS therapy. These findings have important implications for patients with mood disorders, as a large subset of people with major depressive disorder (MDD) show evidence of HPA axis activation, elevated cortisol and, importantly, resistance to the effects of CSs on both the HPA axis and on declarative memory. Thus, resistance to corticosteroids appears to be a consequence of MDD. this study will examine changes in declarative memory, as well as use state-of-the-art high-resolution multimodal neuroimaging, including structural and functional (i.e., task-based and resting state) MRI, in both men and women healthy controls, and, as an exploratory aim, a depressed group, given 3-day exposures to hydrocortisone (160 mg/day) or placebo. The study will translate preclinical findings to humans, provide valuable data on possible sex differences in the response to cortisol and, for the first time, identify specific hippocampal subfields (e.g., CA3/DG) in humans that are most sensitive to acute CS effects. Using resting state fMRI data and whole brain connectomics using graph theoretical approaches, we will determine the effects of cortisol exposure on functional brain networks. Furthermore, this will be the first study to use neuroimaging to compare the brain's response to CSs in people with depression vs. controls, and determine whether depressed people demonstrate glucocorticoid resistance within the hippocampus. We hypothesize that hippocampal response to acute CSs will be greatest in the CA3/DG subfield, greater in women than in men, and that depressed people will show a blunted hippocampal response to CSs compared to controls. A multidisciplinary research team with extensive experience in CS effects on the brain and hippocampal subfield neuroimaging, and a prior history of research collaboration, will conduct the project.
