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 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)
We have found shortened survival in 200 schizophrenics, 100 manics, and 225 depressives by comparing them with the Iowa general population. The numbers of years of shortened survival were estimated from the survival curves of each diagnostic group by sex. Variables affecting shortened survival were diagnostic group, sex, age at admission, and pay status at(More)
A 1-year, double-blind, placebo-controlled, randomized, parallel-group study compared the efficacy and safety of acetyl-L-carnitine hydrochloride (ALCAR) with placebo in patients with probable Alzheimer's disease (AD). Subjects with mild to moderate probable AD, aged 50 or older, were treated with 3 g/day of ALCAR or placebo (1 g tid) for 12 months. Four(More)
This Phase I trial evaluated the interaction between modafinil steady-state and cocaine. Twelve non-treatment seeking, cocaine dependent volunteers received four sets of randomized blinded infusions of saline, 20 mg IV cocaine, and 40 mg IV cocaine. Modafinil was given open label at 0 mg, 400 mg, or 800 mg. Modafinil combined with IV cocaine did not result(More)
A modification of the rank analysis of covariance, suitable for randomly right-censored dependent variate observations, is proposed and studied. The test suggested is based on an appropriate permutation distribution of the rank scores, and for large samples may be conducted by using the chi square distribution. The principal assumptions are that both(More)
OBJECTIVE Prior research suggesting a relationship between pancreatic cancer and depression conducted on clinical populations has been subject to recall bias. We reexamined this association using longitudinal population-based data. METHODS This was a retrospective cohort study using longitudinal insurance claims data. RESULTS Men with mental disorders(More)
Causes of death were studied in a cohort of 200 schizophrenic, 100 manic, and 225 depressive patients who were followed in a historical prospective study. These patients were admitted between 1934 and 1944 and were studied 30 to 40 years later. Five cause of death categories were considered in this analysis: (1) unnatural deaths, (2) neoplasms, (3) diseases(More)
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)
Large research projects offer significant advantages for research, but they pose special data quality problems. Data gathered in such projects may contain a greater absolute number of mistakes because of the people collecting data, the complexity of data processing, and the collation required. We wanted to learn from the types and frequencies of errors(More)
