Abstract: We aimed to examine the satisfaction and the predictors of reported satisfaction with the service offered by a pilot mammography screening service. Information was collected from 481 attenders at the screening clinic and from 318 consecutive attenders at the recall clinic using two different standard self-administered questionnaires covering respectively six and five dimensions of satisfaction. For the screening clinic attenders, mean scores on most subscales indicated quite high levels of satisfaction. There were no significant differences among different samples over time for the perceptions of technical competence of the staff. Decreases in reported level of satisfaction were found for subscales measuring interpersonal skills, information giving, physical surroundings, convenience and accessibility, and general satisfaction. Waiting times, age and marital status were predictors in most satisfaction subscales. For those attending the recall clinic, mean satisfaction scores for most scales were high, except for the scale measuring satisfaction with the way the results were received. The median time between screening and recall visits for women in this study was 27 days (range 3 to 112 days). Attenders were most dissatisfied with the delay in getting results, an area where the service might improve. 相似文献

Clonal osteoblast-like cells derived from a rat osteogenic sarcoma (UMR 106-06) were shown to possess specific, high-affinity binding sites for insulin, with a receptor density of 22,000/cell. The hormone, at physiologic concentrations (1-10 ng/ml), was found to stimulate active K+ transport into these cells, the effect being mediated via the Na+-K+ pump. Alterations in insulin-receptor status by treatment of cells with glucocorticoids or exposure to subphysiologic pH was reflected in parallel changes in the sensitivity of the K+-uptake process to the hormone. We conclude that insulin can directly affect the metabolism of bone cells and that the hormone's action on transmembrane ion transport may be linked to interaction with its cell surface receptors. 相似文献

The broad goal of the Tuskegee Legacy Project (TLP) study was to address, and understand, a range of issues related to the recruitment and retention of Blacks and other minorities in biomedical research studies. The specific aim of this analysis was to compare the self-reported willingness of Blacks, Hispanics, and Whites to participate as research subjects in biomedical studies, as measured by the Likelihood of Participation (LOP) Scale and the Guinea Pig Fear Factor (GPFF) Scale. The Tuskegee Legacy Project Questionnaire, a 60 item instrument, was administered to 1,133 adult Blacks, Hispanics, and non-Hispanic Whites in 4 U.S. cities. The findings revealed no difference in self-reported willingness to participate in biomedical research, as measured by the LOP Scale, between Blacks, Hispanics, and Whites, despite Blacks being 1.8 times as likely as Whites to have a higher fear of participation in biomedical research on the GPFF Scale. 相似文献

Objective: To identify predictors of chronic obstructive pulmonary disease (COPD) severity and assess the relation between COPD severity and risk of cardiovascular outcomes.
Study design and setting: A␣cohort of patients with diagnosed and treated COPD was compiled from the Saskatchewan Health longitudinal databases. We used multivariate modeling to identify predictors of hospitalization for COPD as an indicator of COPD severity, and we used the model to characterize patients according to quintiles of COPD severity. These severity levels were used as independent variables in multivariate models of cardiovascular outcomes.
Results: Determinants of COPD severity included emphysema, recent nebulizer use, home oxygen services, corticosteroid use, frequent bronchodilator use, pneumonia and prior COPD exacerbation. The 20% of patients with the highest COPD severity were 1.27 (CI: 1.07–1.50) times more likely to have arrhythmia, 1.25 (CI: 1.07–1.46) times more likely to have ischemic heart disease, 1.38 (CI: 1.11–1.71) times more likely to have angina, 2.28 (CI: 1.95–2.66) times more likely to have congestive heart failure, and 1.63 (CI: 1.22–2.16) times more likely to die of cardiovascular causes than the least severe 20% of patients.
Conclusions: Patients with more severe COPD, as defined by our model, had higher cardiovascular morbidity and mortality than patients with less severe COPD. 相似文献

Zusammenfassung: Das Hefevorkommen auf intakter Haut verlangt Beachtung, da die fakulta-tiv pathogenen Hefepilze unter besonderen Bedingungen klinische Bedeutung als Krankheits-erreger erlangen. Durch die genaue mykologische Differenzierung der isolierten Hefestämme, die Ermittlung ihrer Häufigkeit und ihrer speziellen iokalen Verteilung konnten wir die notwen-dige Vergleichsbasis schaffen, die im Fall tatsSchlich entstandener Hefemykosen Aussagen über die pathogene Rolle dieser Pilze ermöglicht. Summary: The occurence of yeasts on healthy skin is of practical importance as some yeasts may become pathogens under special clinical conditions. 651 yeast strains were isolated from 135 persons without skin lesions by taking swabs from 24 different skin regions. 126 strains of the genus Candida and among these only 18 strains of C. albicans were found. The data obtained may serve as a basis for comparison with isolates from yeast mycoses of the skin and thus contribute to our knowledge of the pathogenic role of yeasts. 相似文献

Zusammenfassung Der Chromosomensatz einer Walker-Carcinom-Linie, welche auf Ratten, Mäusen und Goldhamstern wächst, wurde untersucht. Die Morphologie der Chromosomen und ihre Zahl ist auf allen drei Tierarten in dieser Tumorlinie gleich. Ein auftretendes submetazentrisches Marker-Chromosom mit heterochromatischem Abschnitt findet sich in gleich hohem Prozentsatz in Tumor-zellen aller drei Tierarten.

Summary The chromosome-sets of a Walker carcinoma line were studied while growing in rats, mice, and gold hamsters. The morphology of the chromosomes and their number for this tumor-line were the same in all three types of animals. A submetacentric marker-chromosome appearing with heterochromatic segments was found in the same high percentage in the tumor cells of all three types of animal.
