Background
How to protect patients from harm is a question of universal interest. Measuring and improving safety culture in care giving units is an important strategy for promoting a safe environment for patients. The Safety Attitudes Questionnaire (SAQ) is the only instrument that measures safety culture in a way which correlates with patient outcome. We have translated the SAQ to Norwegian and validated the translated version. The psychometric properties of the translated questionnaire are presented in this article. 相似文献992.

PURPOSE: The objective of this study was to estimate tobacco use prevalence among the Amish in Holmes County, Ohio, using both self-report and a biochemical marker of nicotine exposure. METHODS: Amish adults (n=134) were interviewed as part of a lifestyle study. Self-reported tobacco use was measured using standardized questions, and cotinine was measured from a saliva sample. The prevalence of smoking, total tobacco use, and misclassification were estimated separately by gender, and then compared to 2 non-Amish groups. One group was selected from 2 counties contained within the Holmes County Amish settlement (n=154) and the other was representative of non-Hispanic whites in the United States (n=4,099). FINDINGS: No Amish women reported current tobacco use and only 2 reported former use. This was significantly different (P<.0001) from the patterns observed among non-Amish in the settlement counties (15.7%) and US white (23.3%) women. The prevalence of tobacco use among Amish men was 17.6% and this was significantly lower than estimates from non-Amish in the settlement counties (38.8%, P=.04) and US white (32.2%, P=.005) men. No Amish women and only 2 Amish men underreported tobacco use and misclassification was similar in the comparison groups. CONCLUSIONS: Tobacco use is significantly lower among adults in the largest Amish settlement in the world compared to their non-Amish neighbors in Appalachia Ohio and US whites. A strength of this study is that self report was verified with a marker of nicotine, a critical measure to include in any study conducted in a group that stigmatizes tobacco use. 相似文献

N-Methyl-N-nitrosourea (MNU) is a potent carcinogen that causes the development of murine thymic lymphomas. MNU-induced tumor incidence varies considerably among different inbred mouse strains. In particular, the AKR strain is highly susceptible, whereas the C57L strain is highly resistant to MNU-induced lymphoma formation. Crosses between AKR and C57L mice were established to investigate the genetic basis for the differential susceptibility of these inbred strains. A strong association between MNU-induced lymphoma development and coat color was observed in (AKR x C57)F2 and AKR x (AKR x C57)F1 progeny such that albino mice developed a higher tumor incidence than nonalbino animals. These data suggest that a locus on chromosome 7 influences tumor development. Analysis of four additional polymorphic loci (D7Rp2, Fes, Hbb, and Int-2) on chromosome 7 in AKR x (AKR x C57)F1 backcross mice revealed a significant linkage between high tumor incidence and homozygous inheritance of AKR alleles at the albino (tyrosinase) and Hbb loci. Thus, inheritance of at least one C57L allele at the albino or Hbb loci was associated with protection against MNU-induced lymphoma development. There was no association between tumor incidence and genotype at the D7Rp2, Fes, or Int-2 loci. Taken together, the data suggest that whereas C57L mice contain a dominant tumor suppressor gene on chromosome 7, in the AKR strain both alleles at this locus are defective resulting in enhanced susceptibility to MNU-induced lymphomagenesis. 相似文献

Appalachians remain at high risk for cancer, heart and lung disease, in part because of their high prevalence of tobacco use; yet, information about their tobacco consumption patterns is limited. The purpose of this study was to describe tobacco consumption variables among rural adult Appalachian tobacco users. Subjects, aged 18 and older (N = 249), participated in a face-to-face interview about tobacco consumption variables and knowledge regarding the health effects of tobacco at fairs in two rural Ohio Appalachian counties. The majority of participants were categorized as precontemplators, although 21 percent were classified in preparation stage of change. Mean age of initiation was 16.6 years and number of cigarettes smoked per day (cpd) was significantly higher for men, as compared to women. One-third of males reported the use of smokeless tobacco. The majority had not tried to quit for more than a year and the average number of previous quit attempts was low. One-half of the sample had been advised in the past to quit by their physician. Few had used nicotine replacement with past quit attempts but greater than half would consider this approach with future attempts. Knowledge about the health effects of smoking indicated that most were aware of the relationship between smoking and cancer but less than one-half recognized its association with heart disease. Those with less education were less informed about the health effects to self and non-smokers. While a sizeable portion expressed interest in quitting, knowledge about the health effects of smoking is lacking, especially with regard to heart disease and among those with less education. 相似文献

Intracardiac teratoma is an extremely rare pediatric neoplasm. We studied the case of a 6-year-old girl with a right intraventricular cardiac mass. The tumor consisted of clusters of monotonous round epithelial cells scattered in a dense fibrotic stroma and was thought to represent an atrioventricular nodal tumor. Three years later the tumor recurred, with multiple mature elements derived from all three germ layers, and was diagnosed as mature cystic teratoma. Still present, however, were multiple areas that were histologically similar to the earlier lesion. Immunostaining revealed strong positivity for insulin, glucagon, somatostatin, and chromogranin consistent with overgrown pancreatic islets of Langerhans within a mature teratoma. 相似文献

Study Objective
To examine the association between race/ethnicity, route of hysterectomy, and risk of inpatient surgical complications.Design
Cross-sectional analysis (Canadian Task Force classification III).Setting
Inpatient hospitals in the United States.Patients and Interventions
There were 114 719 women aged 18 and older from the Nationwide Inpatient Sample who underwent an elective hysterectomy for benign indications using International Classification of Diseases codes.Measurements and Main Results
Multivariable logistic regression was performed to examine the association between race/ethnicity and route of hysterectomy and surgical complications, after adjusting for patient characteristics, clinical factors, and hospital characteristics. Analyses were weighted to provide national estimates of prevalence. The rate of minimally invasive hysterectomy was 55.0% in white women, 28.6% in black women, 50.1% in Hispanic women, and 45.6% in other race/ethnic categories. Compared with white women, black women had a .55 odds (95% confidence interval, .52–.59) of undergoing minimally invasive hysterectomy, after adjusting for patient, clinical, and hospital characteristics. This finding remained consistent across quartiles of median household income of residence, primary payer, and diagnosis of myomas. Among women who had an elective hysterectomy, 6091 experienced a complication, representing an estimated 30 455 women nationwide. The rate of surgical complications was 5.3% in white women, 5.9% in black women, 4.6% in Hispanic women, and 5.1% in women of other racial/ethnic groups. There was no difference in odds of experiencing a surgical complication between white and black women (odds ratio, 1.03; 95% confidence interval, .93–1.13) after adjusting for patient, clinical, and hospital characteristics. This finding remained consistent across quartiles of median household income of residence, primary payer, and route of hysterectomy.Conclusion
Among women undergoing an elective hysterectomy, black women were less likely to receive minimally invasive hysterectomy compared with white women. However, the rate of inpatient surgical complications did not vary significantly by race/ethnicity. Further research is encouraged to identify and address the influential factors behind the disparity in minimally invasive hysterectomy use among black women in the United States. 相似文献999.

A review of the endoscopy reports and pathology results from esophagogastroduodenoscopy (EGD) of all patients with familial adenomatous polyposis (FAP) undergoing such an examination was performed. Two hundred fortyseven patients were identified, with an overall prevalence of duodenal adenomas of 66 percent and of fundic gland polyps of 61 percent. Analysis of our more recent experience (1986 to 1990) shows the prevalence to be 88 percent and 84 percent, respectively. A normal-appearing papilla was adenomatous in 50 percent of cases. No case of periampullary carcinoma developed in patients under surveillance. Routine EGD is indicated for patients with FAP. Duodenal adenomas and fundic gland polyps will occur in the majority of patients.Read at the meeting of The American Society of Colon and Rectal Surgeons, Boston, Massachusetts, May 12 to 17, 1991. 相似文献

Direct effects of metabolic products and sonicated extracts of Porphyromonas gingivalis 2561 on osteogenesis in vitro. 总被引:2,自引:2,他引:0 下载免费PDF全文
It is well documented that oral microorganisms play a significant role in the initiation and progression of periodontal disease. By using various in vitro models, it has been shown that some bacteria considered periodontal pathogens or their products can stimulate bone resorption and some other parameters of osteoblast-like cell activity. However, the effects of these organisms and their products on osteogenesis itself are not known. This study was undertaken to determine the direct effects of metabolic products and sonicated extracts of Porphyromonas gingivalis on bone formation in the chick periosteal osteogenesis model. Cultures of P. gingivalis 2561 were grown under standard anaerobic culture conditions. The spent medium was collected, and following centrifugation, sonicated bacterial extracts were prepared from the bacterial pellet. These were added in various proportions to the chick periosteal osteogenesis cultures. Sonicated extracts were further fractionated into five molecular-size ranges and similarly tested. Parameters of osteogenesis, including alkaline phosphatase activity, calcium and Pi accumulation, and collagen synthesis, were measured on 6-day-old cultures. Compared with controls devoid of bacterial products, osteogenesis was inhibited significantly in cultures treated with either conditioned medium or extracts obtained from P. gingivalis. Various amounts of inhibitory activity were observed in the different ultrafiltration molecular-size fractions, with very profound inhibitory effects observed in the < 5-kDa range. Histological observations indicated the presence of cells, some bone, and/or new fibrous connective tissue at all concentrations, indicating that toxicity was not a factor. These results suggest that periodontal pathogens such as P. gingivalis might contribute to the bone loss in periodontal diseases not only by stimulating resorption but, possibly, by inhibiting bone formation directly. 相似文献
