In adopting the Health Insurance Portability and Accountability Act of 1996 (HIPAA), Congress made a series of small but significant steps toward improving access to health care benefits. The Act's centerpiece is its new requirements for group health plans and for the health insurance industry for assuring portability, access, and renewability of health insurance coverage. Of nearly equal importance is the pilot program established for testing the viability of medical savings accounts. Other health-related changes include adjustments in the rules governing duplication and coordinating of Medicare-related plans, recommendations with respect to privacy of health information of employees, an increase in the deduction for health insurance costs for self-employed individuals, and permission for unemployed persons to make withdrawals from IRAs and other qualified plans for certain medical services' costs. This article summarizes these and other key provisions of HIPAA.  相似文献

"Probable demographic trends and characteristics from the 1990s to the year 2020 [in Mexico] are presented. Then, some of the main economic and social implications of these trends are explored at the aggregate level. Also, some general considerations are given to the possibilities of convergence or conflict between the future demographic evolution, the needs of an open and free-market-oriented economic development strategy, and some social demands associated, probably, to a less controlled and less predictable political system."

In malignant hyperthermia, myophosphorylase reaction shows characteristic changes that take place within minutes: (1) a generally strongly weakened reaction; (2) numerous negatively reacting fibres; (3) frequently, fibre sections that show spotty and/or striatal weak or negative reactions and fibre sections with strong striatal reactions with relatively narrow sarcomere spacings (a "sign of hypercontraction"). Obviously, the morphological findings that show characteristic "striated fibres" are typical of the malignant hyperthermia syndrome! It is important to note that the muscular fibres showing such changes are, as a rule, inconspicuous when using other stains and reactions. These pathological myophosphorylase reactions were observed in five deceased patients (one independently of anaesthesia after an extended walk) and in 19 pigs (18 times after halothane testing and once in an experimental animal with clinical evidence of the presence of malignant hyperthermia). These reactions were not noted in pigs with negative halothane reactivity or prior to halothane testing. They were also not seen in a large number of very different healthy and diseased control and reference cases from our biopsy and autopsy material. Myophosphorylase reaction enables convincing demonstration of malignant hyperthermia, past or present. Hence, it is possible to elucidate puzzling deaths or verify apparently clear death occurring during or subsequent to anaesthesia or simply following stress ("human stress syndrome"). Many of these deaths doubtlessly escape the attention of clinicians using the usual morphological examination methods. However, the reaction cannot be used to identify potential victims.  相似文献
