Self-reported desire to improve colposcopic impressions.

BACKGROUND: Women who participate in cervical cancer screening programs must have access to high quality colposcopy services when their cytology test are abnormal. The purpose of this project is to evaluate colposcopic services currently available in New Hampshire and whether colposcopy providers are willing to network to maintain and improve their colposcopic pattern recognition skills in order to improve their colposcopic correlations. METHODS: A survey was mailed to 1314 providers throughout New Hampshire. The survey ascertained the extent of current colposcopic services in New Hampshire through practitioner and practice demographics, the cervical procedures performed, the self-reported colposcopy skill level, and the self-reported quality of past colposcopic education. It also measured interest in networking with others to improve their colposcopic pattern recognition skills. RESULTS: The survey response rate was 62%. 145 of the 810 respondents (18%) are currently performing colposcopies, indicating a statewide potential colposcopy accommodation rate of 3.5 to 7 women per month per colposcopist. 57% of the physician assistants, 59% of the family physicians, 75% of the gynecologists and 100% of the nurse practitioners were interested in enhancing their colposcopic pattern recognition skills by networking through quarterly meetings. CONCLUSIONS: The crude accommodation rate for colposcopy appears sufficient for the women of New Hampshire although the geographic distribution of the colposcopists is unknown. A majority of the colposcopists were interested in networking to improve their colposcopic pattern recognition skills, which could improve patient care.

Delirium in patients with cancer at the end of life.

PURPOSE: Delirium is a common and distressing syndrome seen in patients with advanced cancer. Behavioral manifestations of delirium, such as agitation, may result in medical intervention, stress to family caregivers, and inpatient hospice admission. The purpose of this study was to examine the frequency, characteristics, and presumed causes of delirium in patients with advanced cancer. DESCRIPTION OF STUDY: Records of all patients with cancer who were admitted to an inpatient hospice facility in 1995 were reviewed retrospectively (N = 210). Patients were classified as delirious based on the clinical judgment of the admitting physician. RESULTS: Delirium was the third most common reason for admission (20%). Male gender (P = .04) and the presence of a primary or metastatic brain tumor (P = .03) were significant risk factors for delirium, while advanced age and primary or metastatic liver, lung, or bone cancer were not. Resolution of the agitation, the most disruptive symptom of delirium, occurred in 69% of patients before death or discharge. CLINICAL IMPLICATIONS: Delirium is common in hospice patients with cancer and is an important cause of family distress and increased cost of care. The recognition of early clinical signs and predisposing factors should facilitate prompt diagnosis. Appropriate intervention is usually successful in alleviating the most distressing symptoms of delirium.

Collection devices for human papillomavirus.

BACKGROUND: Human papillomavirus (HPV) testing has relied to date on samples collected by experienced health professionals. Self-administered testing devices could allow HPV testing to occur in large-scale epidemiologic studies of primary care screening populations. The purpose of this study is to determine whether a self-collection device for cervicovaginal HPV infection could be developed. METHODS: A prospective randomized trial of a consecutive sampling of 93 women, 18 years or older, receiving routine cervical cancer screening and colposcopy in the urban gynecologic clinics in Philadelphia, Pennsylvania, were randomized into 2 arms. Women in arm 1 used a self-administered tampon before the physician-directed swabs of the cervix; in arm 2, women underwent the physician-directed swab testing before using the self-administered tampon. The concordance of HPV DNA positivity between sampling methods detected by a Hybrid Capture HPV tube test for both low- and high-risk types of HPV was the main outcome measure. RESULTS: The concordance rate (ie, women whose cultures were classified as negative on both tests or positive on both tests) for arms 1 and 2 were similar: 78.3% and 80.9%, respectively. CONCLUSIONS: The tampon was equivalent to the physician-directed swab in HPV detection and suggests its feasibility in long-term primary care studies of screening populations.

Is it cost-effective to use a mucosal or paracervical block to relieve the pain and cramping from cryosurgery? A decision model.

BACKGROUND: Cryosurgery is an effective treatment for cervical intraepithelial neoplasia, but it often causes pain and cramping. Both paracervical and mucosal blocks have been shown to provide relief from the pain and cramping associated with cryosurgery. The purpose of this article is to recommend the use of mucosal block, paracervical block, or no block on the basis of which procedure minimizes the costs of averting the pain and cramping that a woman experiences during cryosurgery. METHODS: A decision model was constructed encompassing the options (mucosal block, paracervical block, or no block) that a physician has when performing cryosurgery. The 4 possible outcomes for a patient undergoing cryosurgery were diagrammed as: (1) no pain and no cramping; (2) only cramping; (3) only pain; and (4) both pain and cramping. Each of these outcomes was measured on a 200-mm horizontal visual analog scale. Costs were derived for cryosurgery from the office perspective. Sensitivity analyses were conducted to test the robustness of the analysis. RESULTS: The base case analysis showed that the lowest cost per pain and cramping averted was for women who had a mucosal block before cryosurgery ($153.87), compared with women with a paracervical block ($183.24) and women with no block ($218.83). CONCLUSIONS: A mucosal block is the most cost-effective method to avert the pain and cramping from cryosurgery in women who have taken a nonsteroidal anti-inflammatory drug before the procedure.

Cervical mucosal block effectively reduces the pain and cramping from cryosurgery.

BACKGROUND: Cryosurgery is an effective treatment for squamous intraepithelial lesions, but causes pain and cramping regardless of the particular method of cryosurgery used. The purpose of our study was to determine how effective a four-quadrant cervical mucosal block is in reducing the pain and cramping of cryosurgery. METHODS: Of the 112 women presenting for cryosurgery at the teaching clinics of the University of Missouri-Kansas City School of Medicine at Truman Medical Center-East between September 1995 and September 1996, 87 completed the study. The first 39 women were given the standard treatment of no block with the cryosurgery procedure. The subsequent 48 women were given a four-quadrant submucosal block of 1% lidocaine with 1:100,000 epinephrine 5 minutes before cryosurgery. The intensity of pain and cramping of each part of the procedure was measured on 100-mm visual analog scales. RESULTS: The pain and cramping of cryosurgery were significantly reduced (P < .05) with the mucosal block for all measured parts of the cryosurgery procedure, including pain of the first freeze (39 mm vs 12 mm), cramping of the first freeze (49 mm vs 13 mm), pain of the second freeze (24 mm vs 12 mm), cramping of the second freeze (32 mm vs 18 mm), pain of the total composite procedure (44 mm vs 28 mm), and cramping of the total composite procedure (51 mm vs 21 mm). CONCLUSIONS: A four-quadrant mucosal block effectively reduces the amount of pain and cramping associated with cryosurgery.

Apolipoprotein E epsilon4 association with dementia in a population-based study: The Framingham study.

Apolipoprotein E type 4 allele (apoE epsilon4) is associated with Alzheimer's disease (AD) in the late-onset familial form and in sporadic cases, but the age-associated risk in a randomly sampled elderly population is not established. We examined the association of apoE epsilon4 with AD and other dementias (mainly multi-infarct or dementia following stroke) in 1,030 persons aged 71 to 100 years in the population-based Framingham Study cohort. Kaplan-Meier survival analysis revealed that 55% of the apoE epsilon4/epsilon4 homozygotes developed AD by age 80, whereas 27% of apoE epsilon3/epsilon4 heterozygotes developed AD by age 85, and 9% of those without a 4 allele developed AD by age 85 years. In comparison with persons without a 4 allele, the risk ration for AD was 3.7 (95% CI = 1.9 to 7.5) for apoE epsilon3/epsilon4 heterozygotes and 30.1 (95% CI = 10.7 to 84.4) for apoE epsilon4 homozygotes. ApoE epsilon2 (2/2, 2/3, or 2/4 genotypes) was associated with an absence of AD. One-half (n=21) of the 43 AD patients were either homozygous or heterozygous for apoE epsilon4. We found evidence for an association of apoE epsilon4 with other dementia, primarily multi-infarct dementia and stroke. The risk ratio was 2.3 (95% CI = 0.9 to 6.1) for non-AD dementias among persons with apoE epsilon3/epsilon4. Although the apoE epsilon4 allele is a potent risk factor for AD and may be associated with other forms of dementia, most apoE epsilon4 carriers do not develop dementia, and about one-half of AD is not apoE epsilon4 associated. The low positive predictive value of this marker (0.10) suggest that use of apoE genotyping as a screening test for AD is not supported.

Effect of weight on cardiovascular disease.

Involuntary weight gains worsen all elements of the cardiovascular risk profile, including dyslipidemia, hypertension, insulin-resistant glucose intolerance, left-ventricular hypertrophy, hyperuricemia, and elevated fibrinogen. On the basis of data from the Framingham Heart Study and from other studies, it can be concluded that the degree of overweight is related to the rate of development of cardiovascular disease. After 26 y of follow-up in the Framingham study, each SD increment in relative weight was associated with 15% and 22% increases in cardiovascular events in men and women, respectively. Avoidance of weight gain after the age of 25 y is advisable to reduce cardiovascular mortality. There is a great potential benefit to weight loss, suggesting that weight control as a means for preventing and lessening cardiovascular disease become a national health priority. The optimal weight for avoidance of cardiovascular disease and prolonging life corresponds to a body mass index of 22.6 for men and 21.1 for women.

Central auditory dysfunction, cognitive dysfunction, and dementia in older people.

OBJECTIVES: To determine in older people the relation between auditory dysfunction and cognitive dysfunction, and if central auditory test abnormalities predict the onset of clinical dementia or cognitive decline. DESIGN: Prospective population-based cohort study. SETTING: Framingham Heart Study outpatient biennial examinations 18 and 21. PARTICIPANTS: Members of the Framingham Heart Study cohort with normal findings from cognitive screening tests at biennial examination 18. MEASUREMENTS: Peripheral audiometric thresholds and word recognition in quiet; Synthetic Sentence Identification with Ipsilateral Competing Message (SSI-ICM); Mini-Mental State Examination; and detailed neuropsychological testing of subjects with abnormal findings from the Mini-Mental State Examination. Relative risk of dementia was determined using age-adjusted Cox proportional hazards regression models. RESULTS: Hearing loss significantly lowered performance on the verbal parts of the Mini-Mental State Examination. The relative risk of subsequent clinical dementia or cognitive decline was 6 in subjects with very poor scores (< 50%) in one ear on the SSI-ICM (P = .02); the relative risk was 12.5 if the poor scores were present in both ears (P = .001). CONCLUSIONS: Central auditory dysfunction precedes senile dementia in a significant number of cases and may be an early marker for senile dementia. Hearing tests should be included in the evaluation of persons older than 60 years and in those suspected of having cognitive dysfunction.

The effect of education on the incidence of dementia and Alzheimer's disease in the Framingham Study.

OBJECTIVE: To evaluate whether low educational attainment is a risk factor for the incidence of dementia and Alzheimer's disease (AD) in the Framingham Study and to determine whether age at onset of dementia is earlier in persons with low educational levels. DESIGN: A community-based cohort was studied longitudinally for the development of dementia. Diagnosis was made according to strict criteria by two neurologists and a neuropsychologist. Subtype of dementia and year at onset were determined. Incidence rates were compared in three education groups: < grade school, < high school, and > or = high school. PARTICIPANTS: A total of 3,330 men and women aged 55 to 88 years. RESULTS: During 17 years of follow-up, 258 incident cases of dementia, including 149 AD cases, were identified. Unadjusted incidence rates were significantly elevated (p < 0.05) for dementia and non-AD dementia among the least educated. The age-adjusted relative risk for subjects with a grade school education or less compared with those who earned a high school diploma was 1.31 (95% confidence interval [CI], 0.90 to 1.90) for dementia generally, 1.04 (95% CI, 0.62 to 1.74) for AD, and 1.75 (95% CI, 1.03 to 2.98) for non-AD dementia. Age at onset of dementia did not vary by educational attainment. CONCLUSIONS: After age adjustment, low educational attainment was not a significant risk factor for the incidence of dementia generally or of AD. Low educational attainment was associated with increased risk of non-AD dementia, perhaps because of deleterious smoking habits and other risk factors for stroke in the least-educated individuals. Adequately adjusting for age and examining subtypes of dementia are important in assessing the influence of education on dementia incidence.

The 'preclinical phase' of probable Alzheimer's disease. A 13-year prospective study of the Framingham cohort.

OBJECTIVE: To evaluate the interval between the onset of detectable cognitive impairment and clinical diagnosis in individuals with probable Alzheimer's disease (AD), and to identify the pattern of the earliest changes in cognition in probable AD. DESIGN: Longitudinal follow-up of a community-based cohort sample. In 1976 through 1978, a screening neuropsychological examination was administered to Framingham Study participants. These subjects were then followed up prospectively for development of probable AD for up to 13 years. SETTING: This study was conducted at a community-based center for epidemiologic research. PARTICIPANTS: The surveillance sample consisted of 1045 participants in the Framingham Study aged 65 to 88 years who were free of dementia at the time of the neuropsychological screening examination. MAIN OUTCOME MEASURES: Scores on a group of neuropsychological tests were entered into a series of age- and education-adjusted multiple regression procedures, with the presence or absence of probable AD as the outcome variable. RESULTS: Considered individually, most of the screening neuropsychological measures were significantly related to later AD diagnosis. When stepwise regression procedures were employed, only measures of verbal memory and immediate auditory attention span remained significantly related to AD diagnosis. Of note, subjects later diagnosed with probable AD performed at higher levels than normal subjects on the Digit Span test at initial screening. Regression results were essentially unchanged even when the AD sample was restricted to those individuals for whom the screening examination preceded the clinical onset of dementia by 7 years or more. CONCLUSIONS: These findings support previous contentions that a "preclinical phase" of detectable cognitive deficits can precede the clinical diagnosis of probable AD by many years, and they also support the hypothesis that problems with secondary verbal memory are among the first signs of AD.

Localization of neuropeptides in the nervous system of the brittle star Ophiura ophiura.

Immunocytochemical investigations using antisera against the SALMFamide neuropeptide S1 and RFamide were carried out on whole mounts of the radial nerve cord and circumoral ring of the brittle star Ophiura ophiura. Both antisera show an abundant immunoreactivity in the ectoneural tissue and give similar patterns of distribution. They show that in the radial nerve cord there are discrete populations of neurons organized in an identical pattern in each segment. At the junction with the ring, however, the two proximal segments of the nerve cord are differentiated from the distal ones by increased numbers of immunoreactive neurons. This is probably due to the more complex integrative function in that area. In the ring, immunolabelling is simple and consists of fibre tracts and two local ganglia. In each segment both antisera label either one or two giant neurons the shape of which is similar to that of a class of fibres that have been described from intra-cellular dyefills. The S1- and RFamide-like distributions, although very similar, show some neurons which are only labelled by one antiserum. Since preabsorption controls indicate no cross-reactivity between antisera, there is evidence of two distinct neuropeptides in the nervous system of the brittle star.

Physical activity and mortality in women in the Framingham Heart Study.

Men who are more active live longer, but it is not clear if the same is true for women. We monitored 1404 women aged 50 to 74 who were free of cardiovascular disease. We assessed physical activity levels and ranked subjects into quartiles. After 16 years, 319 (23%) women had died. The relative risk of mortality, compared to the least active quartile, was as follows: second quartile, 0.95 (95% confidence interval [CI] 0.72 to 1.26); third quartile, 0.63 (95% CI 0.46 to 0.86); most active quartile, 0.67 (95% CI 0.48 to 0.92). The relative risks were not changed by adjustment for cardiac risk factors, chronic obstructive pulmonary disease, or cancer or by excluding all subjects who died in the first 6 years (to eliminate occult disease at baseline). There was no association between activity levels and cardiovascular morbidity or mortality. We conclude that women who were more active lived longer; this effect was not the result of decreased cardiovascular disease.

Does exercise reduce mortality rates in the elderly? Experience from the Framingham Heart Study.

Regular physical activity decreases the mortality rate in middle-aged men and probably in middle-aged women. It is unknown whether this is also true in the elderly. We studied 285 men and women aged 75 years or older who were free of cardiovascular disease. Subjects were ranked by baseline physical activity levels and grouped into quartiles. After adjustments were made for cardiac risk factors, chronic obstructive pulmonary disease, and cancer, women in the second most active quartile had a much lower risk of mortality at 10 years (relative risk 0.24, 95% confidence interval 0.12 to 0.51). There was no statistically significant difference in men. There appeared to be an excess of sudden cardiac deaths in the most active women, although this group still lived longer than the least active women. We conclude that women aged 75 years or older who are more active live longer. This benefit may be attenuated in those who are extremely active.

Psychological predictors of hypertension in the Framingham Study. Is there tension in hypertension?

OBJECTIVE: To test the hypothesis that heightened anxiety, heightened anger intensity, and suppressed expression of anger increase the risk of hypertension, using the Framingham Heart Study. DESIGN: A cohort of men and women without evidence of hypertension at baseline were followed up for 18 to 20 years. Baseline measures of anxiety (tension), anger symptoms, and expression of anger (anger-in and anger-out) were taken, along with biological and behavioral predictors of hypertension (initial systolic blood pressure, heart rate, relative weight, age, hematocrit, alcohol intake, smoking, education, and glucose intolerance). PARTICIPANTS: A total of 1123 initially normotensive persons (497 men, 626 women) were included. Analyses were stratified by age (45 to 59 or > or = 60 years) and gender. MAIN OUTCOME MEASURES: Hypertension was defined as either taking medication for hypertension or blood pressures higher than 160/95 mm Hg at a biennial examination. RESULTS: In univariate analyses, middle-aged men who went on to develop hypertension had greater baseline anxiety levels than men who remained normotensive (P = .04). Older hypertensive men had fewer anger symptoms at baseline (P = .04) and were less likely to hold their anger in (P = .01) than normotensives. In multivariate Cox regression analysis including biological predictors, anxiety remained an independent predictor of hypertension in middle-aged men (P = .02). Among older men, anger symptoms and anger-in did not remain significant predictors in the multivariate analysis. Further analysis showed that only middle-aged men with very high levels of anxiety were at increased risk (relative risk, 2.19; 95% confidence interval, 1.22 to 3.94). No psychological variable predicted hypertension in middle-aged or older women in either univariate or multivariate analyses. CONCLUSIONS: The results indicate that among middle-aged men, but not women, anxiety levels are predictive of later incidence of hypertension.

Incidence of dementia and probable Alzheimer's disease in a general population: the Framingham Study.

OBJECTIVE: To determine the incidence of dementia and Alzheimer's disease (AD) in a general population sample. BACKGROUND: Utilizing subjects in the Framingham Study cohort determined to be free of dementia in 1976 to 1978, or on biennial examination 17 in 1982, all new cases of dementia arising in this cohort over a maximum of 10 years of follow-up were ascertained. METHODS: On biennial examination 14/15, a screening neuropsychologic examination was administered to 2,117 subjects, and cases of probable prevalent dementia were identified. Beginning on examination 17 and on all successive biennial examinations, a Mini-Mental State Examination was administered. Subjects previously free of dementia and falling below age-education levels were evaluated by a neurologist and neuropsychologist to determine if dementia was present and to ascertain the dementia type using standard criteria. RESULTS: Five-year incidence of dementia increased with age, doubling in successive 5-year age groups. Dementia incidence rose from 7.0 per 1,000 at ages 65 to 69 to 118.0 per 1,000 at ages 85 to 89 for men and women combined. Incidence of probable AD also doubled with successive quinquennia from 3.5 at ages 65 to 69 to 72.8 per 1,000 at ages 85 to 89 years. Incidence of dementia and of probable AD did not level off with age and was not different in men and women. CONCLUSIONS: In a general population sample, we determined incidence of dementia and of probable AD and will use these incident cases for study of precursors and natural history in this elderly cohort, which has been under close surveillance for over 40 years.

Diet, menopause, and serum cholesterol levels in women: the Framingham Study.

Cross-sectional relationships between diet and total serum cholesterol levels were studied in a sample of 428 women from the Framingham Heart Study Cohort, aged 37 to 70 years, from 1957 to 1960. Multiple linear regression was used to control for total calorie intake, systolic blood pressure, physical activity, Metropolitan relative weight, glucose intolerance, and cigarette smoking. There was little evidence for a relationship between total serum cholesterol and dietary fat intake; whereas a marginally significant direct association was found with total fat in postmenopausal women, total and plant fat and cholesterol were inversely associated, and only cholesterol was significant in premenopausal women. A consistent inverse association was observed between total serum cholesterol levels and intake of protein, particularly from plant sources, and a weak inverse association was found with complex carbohydrate intake. Serum cholesterol in women may be influenced by a number of dietary factors and appears to differ according to menopausal status.

The relation of hearing in the elderly to the presence of cardiovascular disease and cardiovascular risk factors.

Hearing loss with age (presbycusis) is a substantial problem for the elderly. To investigate the possible relation of presbycusis to cardiovascular disease (CVD), the hearing status of a cohort of 1662 elderly men and women was determined and compared with their 30-year prevalence of cardiovascular disease. Age-adjusted multivariate logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) to describe the relation of hearing to cardiovascular disease events, cardiovascular disease risk factors, and both events and risk factors separately for the 676 men and for the 996 women. Cardiovascular disease events were the sum of coronary heart disease, stroke, and intermittent claudication. Five groups of risk factors were studied: hypertension and blood pressure; diabetes, glucose intolerance, and blood glucose level; smoking status and number of pack-years of cigarettes; relative weight; and serum lipid levels, including cholesterol, triglycerides, and lipoprotein fractions. Low-frequency hearing (low pure-tone average, 0.25 to 1.0 kHz) was related to cardiovascular disease events in both genders but more in the women. For women, the OR of having any cardiovascular disease event for a low pure-tone average of 40 dB hearing level was 3.06 (95% CI, 1.84 to 5.10); for a high pure-tone average (average of 4 to 8 kHz) of 40-dB hearing level, the OR for any cardiovascular disease event was 1.75 (95% CI, 1.28 to 2.40). In men with a low pure tone average of 40-dB hearing level, the OR for stroke was 3.46 (95% CI, 1.60 to 7.45) and for coronary heart disease the OR was 1.68 (95% CI, 1.10 to 2.57).(ABSTRACT TRUNCATED AT 250 WORDS)
