A 6-item Orientation-Memory-Concentration Test has been validated as a measure of cognitive impairment. This test predicted the scores on a validated 26-item mental status questionnaire of two patient groups in a skilled nursing home, patients in a health-related facility, and in a senior citizens' center. There was a positive correlation between scores on(More)
Fourteen case histories of persons who had a histological diagnosis of either senile dementia of the Alzheimer type, multiinfarct dementia, or a mixed dementia composed of these two types and who showed evidence of a moderate to severe dementia on psychological testing were rated for the presence of thirteen clinical features comprising Hachinski's Ischemic(More)
Postmortem examination was performed on 137 residents (average age 85.5 years) of a skilled nursing facility whose mental status, memory, and functional status had been evaluated during life. Seventy-eight percent were demented using conservative criteria; 55% had characteristic Alzheimer's disease. Choline acetyltransferase and somatostatin were(More)
Image analysis apparatus was used to count and measure glial and neuronal perikarya in ten size classes in the midfrontal region and superior temporal gyrus of 18 patients with senile dementia of the Alzheimer type for comparison with 12 age-matched normal specimens. Brain weight was about 8% less in the dementia group. The major differences had to do with(More)
OBJECTIVE Peripheral blood cells (PBMCs) from some patients with systemic sclerosis (SSc) express an interferon-alpha (IFNalpha) signature. The aim of this study was to determine whether SSc patient sera could induce IFNalpha and whether IFNalpha induction was associated with specific autoantibodies and/or clinical features of the disease. METHODS SSc(More)
The relative importance of dementia, gender, age and functional status (FS) was examined for relationships to mortality within five years after admission of the subjects to a New York City nursing home for the aged. Using a random sample of 212 of the nursing home's patients, a statistical model was developed to estimate the relative risk of mortality. When(More)
The frequency and timing of p53 inactivation in ulcerative colitis (UC)-associated tumorigenesis were investigated using immunohistochemistry (IHC) to detect p53 protein overexpression in 56 carcinomas and 40 dysplastic epithelia derived from 58 patients with UC undergoing colectomy for neoplasia. p53 DNA in 25 of the carcinomas also was evaluated by(More)
Studies of calcium and phosphorus metabolism and acid-base balance were carried out on three Fleet Ballistic Missile (FBM) submarines during prolonged exposure to elevated concentrations of CO2. The average CO2 concentration in the submarine atmosphere during patrols ranged from 0.85% to 1% CO2. In the three studies, in which 9--15 subjects participated,(More)
T lymphocytes were recovered from recurrent vesicular and ulcerative herpes simplex virus type 2 (HSV-2) lesions from 4 patients and cloned without exogenous secondary antigenic stimulation. Resultant cultures were screened for antigen-specific proliferative and cytotoxic responses. Of the 39 HSV-specific clones recovered, all were CD3-positive; 38 were(More)
