When is physician assisted suicide or euthanasia acceptable?

OBJECTIVES: To discover what factors affect lay people's judgments of the acceptability of physician assisted suicide and euthanasia and how these factors interact. DESIGN: Participants rated the acceptability of either physician assisted suicide or euthanasia for 72 patient vignettes with a five factor design--that is, all combinations of patient's age (three levels); curability of illness (two levels); degree of suffering (two levels); patient's mental status (two levels), and extent of patient's requests for the procedure (three levels). PARTICIPANTS: Convenience sample of 66 young adults, 62 middle aged adults, and 66 older adults living in western France. MAIN MEASUREMENTS: In accordance with the functional theory of cognition of N H Anderson, main effects, and interactions among patient factors and participants' characteristics were investigated by means of both graphs and ANOVA. RESULTS: Patient requests were the most potent determinant of acceptability. Euthanasia was generally less acceptable than physician assisted suicide, but this difference disappeared when requests were repetitive. As their own age increased, participants placed more weight on patient age as a criterion of acceptability. CONCLUSIONS: People's judgments concur with legislation to require a repetition of patients' requests for a life ending act. Younger people, who frequently are decision makers for elderly relatives, place less emphasis on patient's age itself than do older people.     

Do guidelines on euthanasia and physician-assisted suicide in Dutch hospitals and nursing homes reflect the law? A content analysis

To describe the content of practice guidelines on euthanasia and assisted suicide (EAS) and to compare differences between settings and guidelines developed before or after enactment of the euthanasia law in 2002 by means of a content analysis. Most guidelines stated that the attending physician is responsible for the decision to grant or refuse an EAS request. Due care criteria were described in the majority of guidelines, but aspects relevant for assessing these criteria were not always described. Half of the guidelines described the role of the nurse in the performance of euthanasia. Compared with hospital guidelines, nursing home guidelines were more often stricter than the law in excluding patients with dementia (30% vs 4%) and incompetent patients (25% vs 4%). As from 2002, the guidelines were less strict in categorically excluding patients groups (32% vs 64%) and in particular incompetent patients (10% vs 29%). Healthcare institutions should accurately state the boundaries of the law, also when they prefer to set stricter boundaries for their own institution. Only then can guidelines provide adequate support for physicians and nurses in the difficult EAS decision-making process.     

Effect of CD and TK fusion suicide gene on nude mouse osteosarcoma

Objective To observe the effect of herpes simplex virus-thymidine kinase/cytosine deaminase fusion suicide gene on the osteosarcoma growth of nude mice. Methods Osteosarcoma model of nude mouse was made with MG-63 cells injected into axillary fossa. Forty-eight nude mice were divided randomly into 6 groups：     

Are there any differences between antagonist administration on days <6 and ≥6 of Controlled Ovarian Hyperstimulation on assisted reproductive technique outcomes?

Background

The aim of this study was to investigate the cost-effectiveness of antagonist administration on stimulation on days <6 and ≥6 of COH on assisted reproductive technique (ART) outcomes.

A historical view of alveolar echinococcosis, 160 years after the discovery of the first case in humans: part 1. What have we learnt on the distribution of the disease and on its parasitic agent?

Since the first 2 cases observed in southern Germany and the correct identification of a parasite at the origin of the disease by the famous scientist Rudolf Virchow in 1855, the borders of the endemic area of alveolar echinococcosis (AE) have never stopped to expand. The parasite was successively recognized in Switzerland, then in Russia, Austria and France which were long considered as the only endemic areas for the disease. Cases were disclosed in Turkey in 1939; then much attention was paid to Alaska and to Hokkaido, in Japan. The situation totally changed in 1991 after the recognition of the Chinese endemic areas by the international community of scientists. The world map was completed in the beginning of the 21st century by the identification of AE in most of the countries of central/eastern Europe and Baltic States, and by the recognition of cases in central Asia. Up to now, the disease has however never been reported in the South hemisphere and in the United Kingdom. In the mid-1950s, demonstration by Rausch and Schiller in Alaska, and by Vogel in Germany, of the distinction between 2 parasite species responsible respectively for cystic echinococcosis (“hydatid disease”) and AE put an end to the long-lasting debate between the “dualists”, who believed in that theory which eventually proved to be true, and the “unicists”, who believed in a single species responsible for both diseases. At the end of the 20th century, molecular biology fully confirmed the “dualist” theory while adding several new species to the initially described E. granulosus; within the past decade, it also confirmed that little variation existed within Echinococcus (E.) multilocularis species, and that AE-looking infection in some intermediate animal hosts on the Tibetan plateau was indeed due to a new species, distinct from E. multilocularis, named E. shiquicus. Since the 1970s, the unique ecological interactions between the landscape, the hosts, and E. multilocularis have progressively been delineated. The important role of the rodent/lagomorph reservoir size for the maintenance of the parasite cycle has been recognized within the last 2 decades of the 20th century. And the discovery of a close relationship between high densities of small mammals and particularities in land use by agriculture/forestry has stressed the responsibility of political/economic decisions on the contamination pressure. Urbanization of foxes in Europe and Japan and the major role of dogs in China represent the new deals at the beginning of the 21st century regarding definitive hosts and prevention measures.
