Group Number or percentage who have diabetesAge ≥20 years 25.6 million or 11.3% of all people in this age group Age ≥65 years 10.9 million or 26.9% of all people in this age group Fact Sheet uses both fasting glucose and hemoglobin A1c (A1c) levels to derive estimates for undiagnosed diabetes and prediabetes. These tests were chosen because they are most frequently used in clinical practice.Detailed information about the data sources, methods, and references are available at http://www.cdc.gov/ diabetes/pubs/references11.htm.

The blood brain barrier (BBB) poses a significant challenge for drug delivery of macromolecules into the brain. Convection-enhanced delivery (CED) circumvents the BBB through direct intracerebral infusion using a hydrostatic pressure gradient to transfer therapeutic compounds. The efficacy of CED is dependent on the distribution of the therapeutic agent to the targeted region. Here we present a review of convection enhanced delivery of macromolecules, emphasizing the role of tracers in enabling effective delivery anddiscuss current challenges in the field.

In this cohort of patients with post-prostatectomy stress urinary incontinence and a failed primary sling those who underwent a secondary sling procedure were up to 6 times more likely to have persistent incontinence vs those who underwent artificial urinary sphincter placement. These data are useful for counseling patients and planning surgery. We currently recommend placement of an artificial urinary sphincter for patients in whom an initial sling has failed.
