OBJECTIVE Current dietary guidelines recommend adequate intake of magnesium (310-420 mg daily) in order to maintain health and lower the risk of cardiovascular disease. Recent evidence from animal and clinical studies suggests that magnesium may be associated with inflammatory processes. The objective of this study was to determine whether dietary magnesium(More)
OBJECTIVE To delineate the frequency, course, risk factors, and neuroanatomy of hemispatial neglect in a large stroke cohort. METHODS One thousand two hundred eighty-one patients with acute stroke were enrolled in a multicenter trial of an anticoagulant. Presence and severity of neglect were assessed with the NIH Stroke Scale (NIHSS) neglect item,(More)
OBJECTIVE To assess the prevalence of and risk factors for self-reported symptoms suggestive of multiple chemical sensitivities/idiopathic environmental intolerance (MCS/IEI) in Persian Gulf War (PGW) veterans from Iowa and a comparison group of PGW-era military personnel. METHODS A population-based sample of Iowa military personnel was surveyed using a(More)
BACKGROUND: Persons with persistent mental illness are at risk for failure to receive medical services. In order to deliver appropriate preventive and primary care for this population, it is important to determine which chronic medical conditions are most common.

BACKGROUND Nephrogenic systemic fibrosis is a debilitating disease occurring exclusively in patients with renal failure. The aetiology of nephrogenic systemic fibrosis is unclear, but recent reports suggest that exposure to gadolinium for enhancement of magnetic resonance imaging may play a role. In the present study, we assessed the association of exposure(More)
OBJECTIVE To compare the baseline National Institutes of Health Stroke Scale (NIHSS) score and the Trial of Org 10172 in Acute Stroke Treatment (TOAST) stroke subtype as predictors of outcomes at 7 days and 3 months after ischemic stroke. METHODS Using data collected from 1,281 patients enrolled in a clinical trial, subtype of stroke was categorized using(More)
OBJECTIVE To study the relation between acute blood glucose level and outcome from ischemic stroke. BACKGROUND Hyperglycemia may augment acute ischemic brain injury and increase the risk of hemorrhagic transformation of the infarct. METHODS The authors analyzed the relation between admission blood glucose level (within 24 hours from ischemic stroke(More)
Between 1977 and 1984, estimates of hospital-acquired bloodstream infections caused by Candida species increased in the United States from 0.5 to 1.5 per 10,000 admissions (National Nosocomial Infection Study data). We examined crude and attributable mortality rates and excess length of stay in 88 closely matched pairs of cases and controls with illnesses(More)
Although naltrexone has been shown to be effective in the treatment of alcohol dependence, less is known about its efficacy when combined with different behavioral therapies. Previous work has suggested that naltrexone works best when combined with weekly cognitive behavioral therapy (CBT). This study examined the efficacy of naltrexone when combined with(More)
All patients (n = 1,745) with nosocomial bloodstream infection identified between 1986 and 1991 at a single 900-bed tertiary care hospital were studied to identify microbiological factors independently associated with mortality due to the infection. Patients were identified by prospective, case-based surveillance and positive blood cultures. Mortality rates(More)
