While research supports amyloid-β (Aβ) as the etiologic agent of Alzheimer's disease (AD), the mechanism of action remains unclear. Evidence indicates that adducts of RNA caused by oxidation also represent an early phenomenon in AD. It is currently unknown what type of influence these two observations have on each other, if any. We quantified five RNA adducts by gas chromatography/mass spectroscopy across five brain regions from AD cases and age-matched controls. We then used a reductive directed analysis to compare the RNA adducts to common indices of AD neuropathology and various pools of Aβ. Using data from four disease-affected brain …

Assessing Medicare Beneficiaries’ Strength‐Of‐Preference Scores For Health Care Options: How Engaging Does The Elicitation Technique Need To Be?, Trafford Crump, Hilary A. Llewellyn-Thomas

Dartmouth Scholarship

The objective was to determine if participants’ strength‐of‐preference scores for elective health care interventions at the end‐of‐life (EOL) elicited using a non‐engaging technique are affected by their prior use of an engaging elicitation technique.

Declining Length Of Stay For Patients Hospitalized With Ami: Impact On Mortality And Readmissions, Jane Saczynski, Darleen Lessard, Frederick Spencer, Jerry Gurwitz, Joel Gore, Jorge Yarzebski, Robert Goldberg

BACKGROUND: Length of hospital stay after acute myocardial infarction decreased significantly in the 1980s and 1990s. Whether length of stay has continued to decrease during the 2000s, and the impact of decreasing length of stay on rehospitalization and mortality, is unclear. We describe decade-long (1995-2005) trends in length of stay after acute myocardial infarction, and examine whether declining length of stay has impacted early rehospitalization and postdischarge mortality in a population-based sample of hospitalized patients.

METHODS: The study sample consisted of 4184 patients hospitalized with acute myocardial infarction in a central New England metropolitan area during 6 annual periods (1995, …

Management And Outcomes Of Renal Disease And Acute Myocardial Infarction, Paul Santolucito, Dennis Tighe, David Mcmanus, Jorge Yarzebski, Darleen Lessard, Joel Gore, Robert Goldberg

BACKGROUND: Contemporary trends in the management and outcomes of chronic kidney disease patients who develop an acute myocardial infarction have not been adequately described, particularly from the more generalizable perspective of a population-based investigation. METHODS: The study population consisted of 6219 residents of the Worcester, Massachusetts, metropolitan area who were hospitalized with acute myocardial infarction in 6 annual periods between 1995 and 2005. Patients were categorized as having preserved kidney function (n=3154), mild to moderate chronic kidney disease (n=2313), or severe chronic kidney disease (n=752) at the time of hospital admission. RESULTS: Patients with chronic kidney disease were more likely …
