High-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride concentrations are heritable risk factors for vascular disease, but their role in the progression of chronic kidney disease (CKD) is unclear. ⋯ 2-sample Mendelian randomization analysis of data from the largest lipid and CKD cohorts supports genetically higher HDL cholesterol concentration as causally associated with better kidney function. There was no association between genetically altered LDL cholesterol or triglyceride concentration and kidney function. Further analysis of CKD outcomes in HDL cholesterol intervention trials is warranted.

Advance care planning (ACP) empowers patients to consider and communicate their current and future treatment goals. However, it can be an emotionally charged process for patients with kidney disease and their caregivers. This study aimed to describe the perspectives and attitudes of patients with end-stage renal disease (ESRD) and their caregivers toward ACP. ⋯ ACP provides patients with ESRD and their caregivers a conduit for accepting and planning for impending death and to express treatment preferences based on self-dignity and value of living. However, ACP can be considered taboo, may require caregivers to overcome personal and decisional conflict, and may be complex if patients and caregivers are unable to accept the reality of the patient's illness. We suggest that ACP facilitators and clinicians make ACP more acceptable and less confrontational to patients and caregivers and that strategies be put in place to support caregivers who may be experiencing overwhelming grief or who have conflicting goals, particularly when they are called on to make end-of-life decisions.

The diagnosis of acute kidney injury (AKI), which is currently defined as an increase in serum creatinine (Scr) concentration, provides little information on the condition's actual cause. To improve phenotyping of AKI, many urinary biomarkers of tubular injury are being investigated. Because AKI cases are not frequently biopsied, the diagnostic accuracy of concentrations of Scr and urinary biomarkers for histologic acute tubular injury is unknown. ⋯ Concentrations of Scr and kidney injury biomarkers (L-FABP, IL-18, and KIM-1) lack accuracy for diagnosing acute tubular injury in hospitalized deceased donors. Although urinary NGAL concentration had slightly higher discrimination for acute tubular injury than did Scr concentration, its overall AUROC was still modest.

Relationships between early kidney disease, neurocognitive function, and brain anatomy are poorly defined in African Americans with type 2 diabetes mellitus (T2DM). ⋯ In African Americans with T2DM, mildly high UACR and mildly low eGFR were associated with smaller GMV and increased white matter lesion volume. UACR was associated with poorer processing speed and working memory.

Reduced lung function is associated with clinical outcomes such as cardiovascular disease. However, little is known about its association with incident end-stage renal disease (ESRD) and chronic kidney disease (CKD). ⋯ Reduced lung function, particularly lower percent-predicted FVC, is independently associated with CKD progression. Our findings suggest a potential pathophysiologic contribution of reduced lung function to the development of CKD and a need for monitoring kidney function in persons with reduced lung function.
