Image-Guided Biopsies to Identify Mechanisms of Resistance in Patients With Metastatic Castration Resistant Prostate Cancer Treated With 177Lu-PSMA Radioligand Therapy
Recruiting
This clinical trial studies mechanisms of resistance to 177-lutetium prostate specific membrane antigen (177Lu-PSMA) radioligand therapy using image-guided biopsies in patients with castrate-resistant prostate cancer that had spread to other places in the body (metastatic). Diagnostic procedures, such as image guided biopsies, may help in learning how well 177Lu-PSMA works to kill tumor cells and allow doctors to plan better treatment.

Sodium Bicarbonate and Mitochondrial Energetics in Persons With CKD
Recruiting
Skeletal muscle metabolic health is critical for mobility and an underrecognized target of metabolic acidosis in chronic kidney disease. Impaired muscle mitochondrial metabolism underlies poor physical endurance increasing the risk of mobility disability. The proposed project will use precise in vivo tools to study the pathophysiology of poor physical endurance in a clinical trial treating metabolic acidosis among persons living with chronic kidney disease.

Integrating Quantitative MRI and Artificial Intelligence to Improve Prostate Cancer Classification
Recruiting
This study evaluates how new magnetic resonance imaging (MRI) and artificial intelligence techniques improve the image quality and quantitative information for future prostate MRI exams in patients with suspicious of confirmed prostate cancer. The MRI and artificial intelligence techniques developed in this study may improve the accuracy in diagnosing prostate cancer in the future using less invasive techniques than what is currently used.

Brain Health in Breast Cancer Survivors
Recruiting
Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing s... Read More

Pentoxifylline in Diabetic Kidney Disease
Recruiting
Pentoxifylline (PTX) is a medication that has been on the market since 1984 for use in disease in the blood vessels of the legs. There is some preliminary information that it may protect the kidneys from damage due to diabetes and other diseases. "Pentoxifylline in Diabetic Kidney Disease" is a study to bee conducted in 40 VA hospitals across the nation to determine definitively whether or not PTX can prevent worsening of kidney disease and delay death in patients with diabetic kidney disease.
