Parents are the most significant influence on the growth and development of young children. All parents can increase their knowledge of developmental milestones and parenting practices by participating in effective programs that offer information and support. However, there is limited outcome evaluation of programs offering these services. Prevention-focused parenting programs (P-FPPs) are key frontline services designed to educate parents and improve the overall well-being of children. Evaluation of these programs is currently weak; this is not to say they are ineffective, rather that their effectiveness has been poorly evaluated. Rigorous evaluation of P-FPPs would support informed funding and evidence-based policy decisions. The purpose of this study was to conduct a preliminary psychometric analysis of the UpStart Parent Survey (USPS)—a tool developed specifically for evaluating this type of program. Preliminary analysis revealed uni-dimensionality of each scale, strong internal consistency and temporal stability, as well as strong concurrent validity on 9 of the 11 items examined with an urban Canadian population. In its first round of psychometric evaluation, the USPS demonstrated promise as a brief, easy to administer, scientifically rigorous tool for the evaluation of prevention-focused parenting programs. 相似文献

CONTEXT: Hispanics are at increased risk for diabetes, while rural residents have historically had decreased access to care. PURPOSE: To determine whether living in a rural area and being Hispanic confers special risks for diagnosis and control of diabetes. METHODS: We analyzed the Third National Health and Nutrition Examination Survey (1988-1994). Hispanics and non-Hispanic white adults were classified according to rural/urban residence to create 4 ethnicity-residence groups. Investigated outcomes were previously diagnosed and undiagnosed diabetes. Among those with diagnosed diabetes, we investigated control of glucose, hypertension, and lipids. FINDINGS: The prevalence of diagnosed diabetes was greatest for rural residents, especially for rural Hispanics (8.2%) versus that for urban whites (4.6%), rural whites (6.5%), or urban Hispanics (4.5%), (P < .01). However, urban Hispanics were most likely to have undiagnosed diabetes at 3.7%, versus 2.3% of rural whites, 2.8% of urban whites, and 2.7% of rural Hispanics (P = .04). Among people with diagnosed diabetes, there was no difference in glycemic control between the 4 groups. Rural Hispanics with diagnosed diabetes had the greatest prevalence of elevated systolic blood pressure at 45%, compared to 37% of urban whites, 29% of rural whites, 28% of urban Hispanics (P = .01). In regression models controlling for potential confounders, there were no differences among urban and rural whites and Hispanics in the likelihood of undiagnosed diabetes or in glycemic control for those with diagnosed diabetes. CONCLUSIONS: Initiatives that target Hispanic health, and especially diabetes, should acknowledge rural/urban Hispanic health differences. 相似文献

Electron microscopy was used to examine 72 cases of medulloblastoma to better characterize the ultrastructural spectrum of this tumor. Twenty-four cases showed prominent neural differentiation. Twenty-three cases showed minimal (21) or no (2) recognizable neural differentiation, and the remainder of the cases (25) showed intermediate differentiation. All 42 cases tested stained for neuron-specific enolase, 28 for synaptophysin, and 12 for neurofilament protein. All cases showed strong reactivity for glial fibrillary acidic protein (GFAP) within reactive astrocytes. Three cases showed reactivity for GFAP within tumor cells. Medulloblastoma exhibits a broad spectrum of neural differentiation, with nearly all cases showing at least some degree of this change, and it universally exhibits participation of reactive astrocytes which can create a potential for diagnostic confusion. 相似文献

We characterized the quantity and quality of graphs in all pharmaceutical advertisements, in the 10 U.S. medical journals. Four hundred eighty-four unique advertisements (of 3,185 total advertisements) contained 836 glossy and 455 small-print pages. Forty-nine percent of glossy page area was nonscientific figures/images, 0.4% tables, and 1.6% scientific graphs (74 graphs in 64 advertisements). All 74 graphs were univariate displays, 4% were distributions, and 4% contained confidence intervals for summary measures. Extraneous decoration (66%) and redundancy (46%) were common. Fifty-eight percent of graphs presented an outcome relevant to the drug's indication. Numeric distortion, specifically prohibited by FDA regulations, occurred in 36% of graphs. 相似文献

BACKGROUND: Continuity of care has been shown to have a variety of health benefits, but the effect of continuity of care on recognition of common chronic diseases has been underinvestigated. OBJECTIVE: To examine the relationship between continuity of care and the recognition of 3 prevalent chronic diseases: diabetes, hypertension, and hypercholesterolemia. METHODS: We analyzed data from the third National Health and Nutrition Examination Survey, a nationally representative sample of 18 162 adult noninstitutionalized residents of the United States collected from 1988 through 1994. We examined the proportion of unrecognized disease among all individuals with diabetes, hypertension, and hypercholesterolemia according to self-reported level of continuity of care. We used logistic regression to control for possible confounders, including number of disease risk factors. RESULTS: Among persons with diabetes, in adjusted models, those with a usual provider of care had a lower likelihood of having unrecognized disease (odds ratio, 0.30; 95% confidence interval, 0.10-0.95) than those with no usual site or provider of care. Unrecognized hypertension had an unadjusted relationship with level of continuity of care, but continuity of care was not a significant predictor after possible confounders were adjusted for. Unrecognized hypercholesterolemia was not predicted by level of continuity of care. CONCLUSIONS: Continuity of care has some benefits in terms of recognizing chronic disease, although benefits appear to be disease specific. More research needs to be conducted to elucidate the complex relationship between continuity and disease recognition. 相似文献

STUDY OBJECTIVE: We sought to determine whether knowledge of vital signs changes nurse triage designations (TDs). We also sought to determine whether patient age and ability to communicate modify the effect of vital signs on triage decisions. METHODS: We performed a prospective observational study, in 24 emergency departments, of nurse-assigned TDs of all ED patients undergoing triage. Nurses performed their typical triage routine, except that they chose 1 of 5 hypothetical TDs (call 911, ED <2 hours, physician's office 2 to 8 hours, physician's office 8 to 24 hours, or home care) before and after measurement of vital signs. The main outcome measure was the change of TD after knowledge of a patient's vital signs, with stratification on the basis of patient age and communication barriers. The secondary outcome was the final ED disposition. RESULTS: Six hundred twenty-five experienced triage nurses at 24 different EDs collected data on 14,285 patients. TDs were downgraded (decreased in urgency) in 2.4% of patients, and 5.5% were upgraded (increased in urgency) after vital signs were known. Changes were more likely to occur in the young (< or = 2 years old; 11.4%) and the elderly (> or = 75 years old; 9.9%) than in those 3 to 74 years of age (7.5%). When nurses reported a communication barrier, a change in post-vital signs TD was also more common (11.2% versus 7.7%). The post-vital signs TD better predicted patient ED disposition. CONCLUSION: In this sample, 92.1% of the nurses' TDs were not affected by the knowledge of patient vital signs. For the other 7.9%, including many patients from vulnerable populations, the vital signs changed the nurses' assessments of the patients' triage designation. Methods of triage that do not determine vital signs may not adequately reflect the urgency of the patient's presentation. 相似文献

A young woman with a melanoma of the left forearm was found to have a right lung mass. This was initially interpreted as metastatic melanoma on the basis of clinical, radiographic, and light microscopic features, together with positive staining of tumor cells with antibody HMB-45. Electron microscopic examination performed for confirmation of the diagnosis revealed no evidence of melanocytic differentiation. Instead, there were features suggestive of the alternative diagnosis of sclerosing hemangioma (SH). This diagnosis was confirmed with additional immunocytochemical stains. To the authors' knowledge this is the first report of HMB-45 positivity in SH. This case illustrates a potentially disastrous diagnostic pitfall in interpreting lung tumors in patients with melanoma, and the vital role of electron microscopy in resolving conflicting and/or misleading immunocytochemical results. 相似文献
