Conflict between substitute decision makers (SDMs) and health care providers in the intensive care unit is commonly related to goals of treatment at the end of life. Based on recent court decisions, even medical consensus that ongoing treatment is not clinically indicated cannot justify withdrawal of mechanical ventilation without consent from the SDM. Cardiopulmonary resuscitation (CPR), similar to mechanical ventilation, is a life-sustaining therapy that can result in disagreement between SDMs and clinicians. In contrast to mechanical ventilation, in cases for which CPR is judged by the medical team to not be clinically indicated, there is no explicit or case law in Canada that dictates that withholding/not offering of CPR requires the consent of SDMs. In such cases, physicians can ethically and legally not offer CPR, even against SDM or patient wishes. To ensure that nonclinically indicated CPR is not inappropriately performed, hospitals should consider developing ‘scope of treatment’ forms that make it clear that even if CPR is desired, the individual components of resuscitation to be offered, if any, will be dictated by the medical team’s clinical assessment. 相似文献

Statement of problem
The polymerization conditions of an autopolymerizing resin affect its physical properties, and at chairside, 3 different methods are commonly used: cooling in cold water, warming in warm water, and heating in hot water. However, the effects of polymerization temperature on the physicomechanical properties of autopolymerizing resin are unclear.Purpose
The purpose of this in vitro study was to determine the effect of polymerization temperature on the physicomechanical properties of autopolymerizing resin, including shrinkage, water absorption, surface roughness, amount of residual monomer, and flexural strength.Material and methods
The experiment was designed to simulate a direct technique commonly used for the fabrication of interim crowns. Autopolymerizing resin specimens were made according to the powder-to-liquid ratio recommended by the manufacturer and soaked in water at 13°C, 37°C, or 60°C for 2 minutes to mold the resin until polymerization was completed 4 minutes after mixing. Shrinkage, water absorption rate, surface roughness, residual monomer, and flexural strength were measured immediately after polymerization and after 1, 3, and 7 days in distilled water at 37°C. Differences among these properties among the 3 different temperatures groups were statistically analyzed by using 1-way ANOVA and the Tukey honest significant difference test (α=.05).Results
Shrinkage tests showed that the 13°C group had significantly lower shrinkage (P=.004 for 37°C and P<.001 for 60°C) than the other groups immediately after specimen preparation. The 13°C group had significantly higher surface roughness after 0 (P<.001 for 37°C and P<.001 for 60°C), 1 (P=.025 for 37°C and P=.012 for 60°C), 3 (P<.001 for 37°C and P<.001 for 60°C), and 7 days (P<.001 for 37°C and P<.001 for 60°C) than those in the other groups and significantly higher water absorption rates (P=.033 for 37°C and P<.001 for 60°C) than the other groups during the 7 days after fabrication. However, the 13°C group showed significantly higher weight percentage of residual monomers than the 60°C group at 0 (P<.001) and 1 day (P<.001). Finally, 3-point bend tests showed that the 13°C group had significantly lower flexural strength at 0 (P<.001), 1 (P<.001), 3 (P<.001), and 7 days (P<.001) than the other groups.Conclusions
The temperature environment during dental chairside polymerization of the autopolymerizing resin affected the physicomechanical properties of shrinkage, water absorption rate, surface roughness, residual monomer, and flexural strength. 相似文献999.

The US health care model continues to struggle with providing chronic disease management. Innovation focusing on improving care delivery systems to bridge this gap will be necessary to improve chronic care in the United States. This quality improvement project focused on patients with type 2 diabetes. This innovation was designed to change patient and provider engagement in follow-up care by providing a protected synchronous time in the form of a scheduled phone call to work on glycemic goals through improving patient’s diabetes self-management techniques and, when appropriate, medication titration. A standardized tool (the Diabetes Treatment Satisfaction Questionnaire) was used to assess patient satisfaction with this intervention. 相似文献

Using data for England and Wales during the years 1840-2000, a negative relation is found between economic growth--measured by the rate of growth of gross domestic product (GDP)--and health progress--as indexed by the annual increase in life expectancy at birth (LEB). That is, the lower is the rate of growth of the economy, the greater is the annual increase in LEB for both males and females. This effect is much stronger, however, in 1900-1950 than in 1950-2000, and is very weak in the 19th century. It appears basically at lag zero, though some short-lag effects of the same negative sign are found. In the other direction of causality, there are very small effects of the change in LEB on economic growth. These results add to an emerging consensus that in the context of long-term declining trends, mortality oscillates procyclically during the business cycle, declining faster in recessions. Therefore, LEB increases faster during recessions than during expansions. The investigation also shows how the relation between economic growth and health progress changed in England and Wales during the study period. No evidence of cointegration between income--as indexed by GDP or GDP per capita--and health--as indexed by LEB--is found. 相似文献
