Most crimes with child victims are not reported to police, nor do child victims access other professional victim services, despite evidence that these yield positive outcomes. This article develops a conceptual framework about the barriers to such access: (a) the reluctance to define the crime episodes or their consequences as serious, criminal, harmful, or warranting intervention; (b) the extra authorities, including parents and schools, who mediate between victims and police or services; (c) developmental issues, such as concerns about autonomy; (d) attitudinal and emotional obstacles; and (e) time and expense factors. This article suggests the need for initiatives to stimulate reporting and help seeking, such as more publicity about the seriousness of juvenile victimization, more justice-system involvement with schools, more child and family friendly police services, and an emphasis on attractive outcomes such as justice and empowerment. 相似文献

Objective
Many trials of new therapies for cardiovascular disease include economic measures to assess the impact of treatment on healthcare costs, however, it is difficult to compare results between trials due to variation in methods for assigning costs. Therefore we developed a standard library of inpatient hospital costs for major cardiovascular events commonly reported in trials for new cardiovascular therapies.Design
Mean and median hospital charges for each event were calculated from Medicare admissions selected by ICD-9-CM codes from the most recent Healthcare Cost and Utilisation Project (HCUP) Nationwide Inpatient Sample (NIS) database available. Charges were converted to costs using the cost-to-charge ratio from the most recent Medicare cost report data and updated to 1999 using a model derived from the Medicare Payment Advisory Commission (MedPAC) forecast to recommend annual updates to Medicare.Results
Total hospital costs for medical events ranged from $US3654 (1999 values) to $US7833; total hospital costs for surgery and procedures ranged from $US7054 to $US46 317. The distribution of hospital costs is skewed with median costs and lengths of stay lower than mean values. Costs for patients who died in the hospital were generally higher than costs for patients who were discharged.Conclusions
The library of costs was calculated using a uniform method based on publicly available and easily accessible data and may be updated from year to year. This method provides standardised estimates of hospital costs that can be used in economic analyses of cardiovascular clinical trials. 相似文献63.

Most US medical schools have adopted programmes of affirmative action but these have not been completely successful in increasing diversity. There have been some law suits against medical schools brought by rejected students claiming reverse discrimination. Most minority groups are experiencing a downturn in representation in medicine. The movement to humanize medicine through widening entrance criteria has faded away. 相似文献

This article examines the reasons why proprietary hospital chains have become interested in buying or managing academic health center hospitals. Among the explanations that are discussed are such factors as vertical integration of health care, chain legitimation, integration of finance and delivery systems, and short-term profit potential. These factors are further examined through the use of a structured analysis of the interpenetration of proprietary chain hospitals and academic medical centers. We also discuss the consequences of these linkages in terms of such issues as continued educational mission, types of sponsored research programs, degree of indigent care provision, and changes in the nature of physician and other health worker training. The larger social implications of the movement of proprietary chains into tertiary medical care are evaluated. 相似文献

Astrocyte growth stimulation by a soluble factor produced by cerebral endothelial cells in vitro 总被引:6,自引:0,他引:6

Conditioned medium from isolated cerebral capillary endothelial cells (ECCM) was found to promote DNA synthesis in astrocytes and pericytes, but not in oligodendrocytes or endothelial cells (EC) in vitro. The astrocyte was the cell of primary interest and the cell tested in the following experiments. The effect of ECCM on astrocytes was concentration and time dependent. The growth factor was released by EC into the medium in a cumulative manner for up to 72 hours. This release was not the result of a nonspecific leakage of an internal store, since the DNA synthetic activity of cell lysates was negligible. The growth factor secretion per cell was higher in sparse than in confluent EC cultures and was partially inhibited by preincubation of EC with interleukin-1. The DNA synthetic activity was due to a peptide, different from basic fibroblast growth factor, transferrin, bovine fibronectin and platelet derived growth factor, with a molecular weight greater than 50,000. The peptide derived from the cerebral capillary EC could be involved in the local signaling between cell types that control new vessel formation in development, in regeneration after brain tissue injury, or in tumor formation. 相似文献

The walk-in chains: the proprietarization of ambulatory care 总被引:1,自引:0,他引:1
In this article we examine the previously little-studied development in U.S. health care--the growth of a proprietary ambulatory care system composed of health maintenance organization, urgent care centers, ambulatory surgicenters, ambulatory diagnostic centers, large group practices, and other delivery modalities. The growth of this system as a result of the ease of access to capital, limited or nonexistent regulation through Certificate of Need or other mechanisms, the growing surplus of physicians, decreases in the use of hospitals as a result of changed insurance benefits and inpatient utilization review, new developments in biotechnology, and computerization and miniaturization of new technological advances is discussed. The reasons for the expanded growth of proprietary chains over nonprofit systems of ambulatory care are also discussed. The article concludes with a discussion of the negative consequences for individual health and the health care system that may be generated by the continued growth of proprietary ambulatory care. 相似文献

Summary A spectrum of thick filament-related structures exhibiting novel structural features is isolated in addition to the normal thick filaments fromunc-15 andunc-82 mutants ofCaenorhabditis elegans. Many assemblages have multiple myosin-coated filaments extending from both ends of central domains exhibiting paracrystalline paramyosin. The filament ends resemble the polar core structures of native thick filaments. Assemblages with filaments at only one end and short thick filaments that branch are also present. This spectrum of novel structures accumulates at high levels in specific mutants due to alterations in paramyosin or other interacting proteins. The multifilament structures are either alternative assemblages of thick filament proteins and substructures or usually transient nucleation centres active in the assembly of thick filaments which are favoured under mutant conditions. 相似文献

Direct sagittal CT imaging of the TMJ provides several distinct advantages. Most significant is that direct imaging allows noninvasive evaluation of the disk. Direct sagittal CT scanning can confirm a clinical diagnosis of internal derangements as well as monitor splints intended for recapturing of the disk. Furthermore, the CT direct imaging allows excellent views of the bony architecture similar to those obtained with tomography. Used with clinical history and physical examination, CT can provide an excellent diagnostic modality to help provide better care for patients with internal derangement of the TMJ. 相似文献

T cell cytokines are known to play a major role in determining protection and pathology in infectious disease. It has recently become clear that IL-12 is a key inducer of the type 1 T cell cytokine pattern characterized by production of IFN-gamma. Conversely, IL-10 down-regulates IL-12 production and type 1 cytokine responses. We have investigated whether IL-12 and IL-10 might be involved in a chronic inflammatory reaction, atherosclerosis. In atherosclerotic plaques, we found strong expression of IFN-gamma but not IL-4 mRNAs as compared to normal arteries. IL-12 p40 mRNA and IL-12 p70 protein were also found to be abundant in atherosclerotic plaques. IL-12 was induced in monocytes in vitro in response to highly oxidized LDL but not minimally modified LDL. The cross-regulatory role of IL-10 was indicated by the expression of IL-10 in some atherosclerotic lesions, and the demonstration that exogenous rIL-10 inhibited LDL-induced IL-12 release. These data suggest that the balance between IL-12 and IL-10 production contributes to the level of immune-mediated tissue injury in atherosclerotsis. 相似文献
