论脑死亡标准中的法律问题

随着医学科学的迅速发展 ,传统的死亡标准已不能适应现实的需要 ,更阻碍了有关医学的进一步发展。有学者提出脑死亡概念 ,国外也有相关立法 ,我国脑死亡立法也已进入实质性程序。本文对脑死亡的概念、意义、标准及国外的规定作了初步的阐述 ,并对我国的立法提出建议。     

Medical devices; immunology and microbiology devices; classification of cystic fibrosis transmembrane conductance regulator gene mutation detection system. Final rule

The Food and Drug Administration (FDA) is classifying the cystic fibrosis transmembrane conductance regulator (CFTR) gene mutation detection systems into class II (special controls). The special control that will apply to the device is the guidance document entitled "Class II Special Controls Guidance Document: CFTR Gene Mutation Detection Systems." The agency is classifying the device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device. Elsewhere in this issue of the Federal Register, FDA is announcing the availability of the guidance document that will serve as the special control for the device.     

Possession, use, and transfer of select agents and toxins--reconstructed replication competent forms of the 1918 pandemic influenza virus containing any portion of the coding regions of all eight gene segments. Interim final rule

We are adding reconstructed replication competent forms of the 1918 pandemic influenza virus containing any portion of the coding regions of all eight gene segments to the list of HHS select agents and toxins. We are taking this action for several reasons. First the pandemic influenza virus of 1918-19 killed up to 50 million people worldwide, including an estimated 675,000 deaths in the United States. Also, the complete coding sequence for the 1918 pandemic influenza A H1N1 virus was recently identified, which will make it possible for those with knowledge of reverse genetics to reconstruct this virus. In addition, the first published study on a reconstructed 1918 pandemic influenza virus demonstrated the high virulence of this virus in cell culture, embryonated eggs, and in mice relative to other human influenza viruses. Therefore, we have determined that the reconstructed replication competent forms of the 1918 pandemic influenza virus containing any portion of the coding regions of all eight gene segments have the potential to pose a severe threat to public health and safety.     

Registration of food facilities under the Public Health Security and Bioterrorism Preparedness and Response Act of 2002. Final rule

The Food and Drug Administration (FDA) is issuing a final regulation that confirms the interim final rule entitled "Registration of Food Facilities Under the Public Health Security and Bioterrorism Preparedness and Response Act of 2002" (68 FR 58894, October 10, 2003 (interim final rule) as corrected by a technical amendment (69 FR 29428, May 24, 2004), and responds to comments submitted in response to the request for comments in the interim final rule. This final rule affirms the interim final rule's requirement that domestic and foreign facilities that manufacture/process, pack, or hold food for human or animal consumption in the United States be registered with FDA by December 12, 2003. The interim final rule implemented the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 (the Bioterrorism Act), which requires domestic and foreign facilities to be registered with FDA by December 12, 2003. This final rule does not make any changes to the regulatory requirements established by the interim final rule.     

Electronic products; performance standard for diagnostic x-ray systems and their major components. Final rule

The Food and Drug Administration (FDA) is issuing a final rule to amend the Federal performance standard for diagnostic x-ray systems and their major components (the performance standard). The agency is taking this action to update the performance standard to account for changes in technology and use of radiographic and fluoroscopic x-ray systems and to fully utilize the International System of Units to describe radiation-related quantities and their units when used in the performance standard. For clarity and ease of understanding, FDA is republishing the complete contents, as amended, of three sections of the performance standard regulations and is amending a fourth section without republishing it in its entirety. This action is being taken under the Federal Food, Drug, and Cosmetic Act (the act), as amended by the Safe Medical Devices Act of 1990 (SMDA).     

Beverages: bottled water. Final rule

The Food and Drug Administration (FDA) is amending its bottled water quality standard regulations by revising the existing allowable level for the contaminant arsenic. As a consequence, bottled water manufacturers are required to monitor their finished bottled water products for arsenic at least once each year under the current good manufacturing practice (CGMP) regulations for bottled water. Bottled water manufacturers are also required to monitor their source water for arsenic as often as necessary, but at least once every year unless they meet the criteria for the source water monitoring exemptions under the CGMP regulations. This final rule will ensure that the minimum quality of bottled water, as affected by arsenic, remains comparable with the quality of public drinking water that meets the Environmental Protection Agency's (EPA's) standards.     

Sexual and nonsexual offenders with intellectual and learning disabilities: a comparison of characteristics, referral patterns, and outcome

This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic details, and outcome up to 7 years after referral. The cohorts are older than one would expect from the criminology literature, and, at about 33%, the incidence of mental illness is consistent with some previous studies. A greater proportion of sex offenders had criminal justice involvement and a formal disposal from court. Fire raising was not overly represented as an offense. There was a higher rate of reoffending in the nonsexual cohort, which persisted up to 7 years. Investigating only reoffenders, there was a considerable amount of harm reduction recorded up to 7 years, statistically significant up to 5 years following initial referral.     

Medical devices; obstetrical and gynecological devices; classification of the assisted reproduction laser system. Final rule

The Food and Drug Administration (FDA) is classifying the assisted reproduction laser system into class II (special controls). The special control that will apply to the device is the guidance document entitled "Class II Special Controls Guidance Document: Assisted Reproduction Laser Systems." The agency is classifying this device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device. Elsewhere in this issue of the Federal Register, FDA is publishing a notice of availability of the guidance document that is the special control for this device.     

Current good tissue practice for human cell, tissue, and cellular and tissue-based product establishments; inspection and enforcement. Final rule

The Food and Drug Administration (FDA) is requiring human cell, tissue, and cellular and tissue-based product (HCT/P) establishments to follow current good tissue practice (CGTP), which governs the methods used in, and the facilities and controls used for, the manufacture of HCT/Ps; recordkeeping; and the establishment of a quality program. The agency is also issuing new regulations pertaining to labeling, reporting, inspections, and enforcement that will apply to manufacturers of those HCT/Ps regulated solely under the authority of the Public Health Service Act (PHS Act), and not as drugs, devices, and/or biological products. The agency's actions are intended to improve protection of the public health while keeping regulatory burden to a minimum, which in turn would encourage significant innovation.
