BACKGROUND Drug-resistant Acinetobacter species are problematic in tertiary-care hospitals. We describe the epidemiology, resistance patterns, and outcomes of older adults with Acinetobacter infection in community hospitals. METHODS We queried the microbiology databases of the Oakwood Healthcare System (4 hospitals with 632, 259, 199, and 168 beds) for(More)
Hypertension, diabetes, obesity, and aging are associated with increased arterial stiffness. Both insulin resistance and hyperglycemia may contribute to the development of arterial stiffness. Older nondiabetic hypertensive adults were recruited to test the following hypotheses: (1) insulin resistance is associated with arterial stiffness, and (2) this(More)
BACKGROUND Markers of collagen turnover have not been well studied in the context of cardiovascular disease in patients with chronic kidney disease (CKD). We investigated the associations between serum markers of collagen turnover [N-terminal procollagen type 3 propeptide (PIIINP) and carboxy-terminal telopeptide (C1TP)] and both pulse wave velocity (PWV)(More)
The objective of this study was to investigate complications, urinary incontinence symptoms, and overall satisfaction in patients undergoing the tension-free vaginal tape-SECUR (TVT-S) for stress urinary incontinence (SUI). We reviewed consecutive patients treated with TVT-S between April, 2006 and August, 2007, in a urogynecology practice. Outcomes(More)
Autophagy, a cellular housekeeping process, is essential to maintain tissue homeostasis, particularly in long-lived cells such as cardiomyocytes. Autophagic activity declines with age and may explain many features of age-related cardiac dysfunction. In this review we summarize the current state of knowledge regarding age-related changes in autophagy in the(More)
BACKGROUND The homeostatic intracellular repair response (HIR2) is an endogenous beneficial pathway that eliminates damaged mitochondria and dysfunctional proteins in response to stress. The underlying mechanism is adaptive autophagy. The purpose of this study was to determine whether the HIR2 response is activated in the heart in patients undergoing(More)
BACKGROUND Previous studies demonstrated an association between asthma and idiopathic dilated cardiomyopathy (IDCM), raising concerns regarding chronic beta-agonist inhaler use. The purpose of this investigation was to replicate that association. METHODS AND RESULTS We identified 67 patients with IDCM and 130 controls with predominately ischemic(More)
BACKGROUND The predictors of arterial stiffness across the spectrum of renal function are unclear. These predictors were investigated across a wide range of estimated glomerular filtration rates (eGFR). METHODS Carotid-femoral pulse wave velocity (PWV; an index of arterial stiffness) was measured in 264 subjects with chronic kidney disease (CKD) stages(More)
This study tests the hypothesis that increased arterial stiffness is associated with postural hypotension in older adults. Aortic pulse wave velocity and postural blood pressure (BP) response were assessed in 49 nondiabetic community-dwelling normotensive (n=27) and hypertensive (n=22) older adults (mean age+/-SD, 71+/-6.7 years) who were not receiving(More)
BACKGROUND Long-term acute care (LTAC) facilities admit patients with complex, advanced disease states. Study aims were to determine the burden posed on hospitals associated with LTAC exposure and analyze the differences between "present on admission" (POA) multidrug-resistant (MDR), gram-negative organisms (GNO) and POA MDR gram-positive organisms (GPO).(More)
