Rationale & Objective: Chronic kidney disease (CKD) populations face an elevated risk of cardiovascular disease (CVD), yet many remain undertreated with statins for primary prevention of CVD despite meeting eligibility criteria. We examined trends in statin use for primary prevention among individuals with CKD before and after the release of the 2013 Kidney Disease: Improving Global Outcomes (KDIGO) guideline recommending statin use for lipid management in selected adults with CKD.

Study Design: Cross-sectional time-trend analysis.

Perineuronal nets (PNNs) are a specialized extracellular matrix that surround certain populations of neurons, including (inhibitory) parvalbumin (PV) expressing-interneurons throughout the brain and (excitatory) CA2 pyramidal neurons in hippocampus. PNNs are thought to regulate synaptic plasticity by stabilizing synapses and as such, could regulate learning and memory. Most often, PNN functions are queried using enzymatic degradation with chondroitinase, but that approach does not differentiate PNNs on CA2 neurons from those on adjacent PV cells.

Thus, the aim of this study was to identify categories of older adults' care experience preferences and to examine similarities and differences across different age groups.

Methods: The initial categories of older adults' care experience preferences were identified through a qualitative review of narrative text (n = 3134) in the ADVault data set.
