Currently, kidney disease affects up to 20% of the US population and is a strong contributor to morbidity and mortality in these patients. Specific therapies and diagnostic tools for kidney disease have been very slow to develop because of the absence of high quality samples and data that can be used for research studies. The purpose of this study is to develop a registry and sample bank called Poseidon (Prevention, Optimizing Safety, Early Intervention and DetectiOn in Nephrology) biobank that can be used for future research. In this study, patients can consent to donating their residual kidney tissue if they undergo a kidney biopsy and blood or urine during routine clinical care procedures. We will also collect blood and urine outside of clinical care.This study will allow biomedical research the ability to obtain specimens from patients with relevant diseases and appropriate clinical data. This study will collect patient demographic, clinical and historical data for a registry and patient samples will be deposited in the Poseidon biobank. Patients do not have to be diagnosed with Kidney Disease to be included in this study.

This is a prospective, multicenter observational study to investigate clinical markers of nutritional status, physical frailty, and sarcopenia in adults with CF spanning a range of lung impairment and to identify barriers and risk factors to optimize nutrition and physical functioning in this patient population. Repeat measurements of body composition and physical function by various methods will be taken during the study and compared to clinical outcomes, as well as with each other. Smaller sub-set studies will be performed to assess bioimpedance analysis (BIA) and/or ultrasound as measures of body composition. Two cohorts matched by age, sex, race, and CFTR genotype severity will be enrolled: (1) those with FEV1 <60% and (2) those with FEV1 ≥60%.

Profound racial inequities in statin use and cholesterol control mirror racial disparities in prostate cancer, where Black men are less likely to use a statin and have worse cholesterol control, are 78% more likely to be diagnosed with prostate cancer, and twice as likely to die from the disease compared to White men. Despite these parallels, the role of cholesterol control in prostate cancer racial disparities is poorly understood. Here, we investigate whether inequities in cholesterol control between Black and White men not using statins compared to cholesterol control in statin users contribute to prostate cancer racial disparities through interactions with tumor metabolism and the tumor microenvironment (TME), a novel concept supported by strong rationale.
