The financing and regulation of medical devices in the United States.

This paper focuses on two major areas of US federal policy that relate to medical devices, regulations regarding premarketing approval and arrangements for financing the use of devices. Other relevant areas, such as patents, liability, and taxation, are discussed more briefly. In 1976 legislation authorized the federal Food and Drug Administration (FDA) to require manufacturers of medical devices to show that their products meet acceptable levels of safety and effectiveness. FDA has classified each device into one of three classes according to the extent of regulation needed to ensure safety and effectiveness. Although all devices must conform to general manufacturing controls and some to premarketing approval, no performance standards have yet been developed. About two-thirds of all expenditures for medical care in the United States are paid by private or public insurers. Although procedures vary for institutional and individual providers, payment is usually made after the medical care has been provided and covers the provider's costs or charges. Prevailing insurance coverage and payment methods contain incentives for the innovation and use of medical devices that are part of mainstream medical care. At the same time, these financial arrangements discourage preventive and rehabilitative devices, which are generally excluded from insurance coverage.

[Blood alcohol value and responsibility in the jurisdiction of the German Federal Court].

The author shows, what effect as a circumstantial evidence the ascertained or the possible blood alcohol concentration has in the jurisdiction of the Federal Court as far as the responsibility is to be judged on. He thinks, that the dispute, which seemed to be at hand between the decisions of the 1. and 4. penal senate, is not to be noticed. According to his opinion the blood alcohol concentration has an outstanding importance for the jurisdiction on the responsibility.

Legal regulation of human gene therapy.

The adequacy of existing legal mechanisms to regulate clinical trials of human gene therapy is examined. Existing legal controls include the federal Guidelines for Research Involving Recombinant DNA Molecules and federal regulations for the protection of human subjects. Another significant mechanism is provided by judicial oversight, i.e., judicial decisions involving recombinant DNA research. Human gene therapy does raise new issues that still must be resolved. At least two weaknesses exist in the present regulatory system: first, Recombinant DNA Advisory Committee (RAC) only has authority over federally funded research, not work done with private support, and second, RAC is not mandated to focus on difficult ethical issues, e.g., germ-line therapy, that arise from human genetic engineering technology.

[A rapid technique for isolation of Escherichia coli type I in food (author's transl)].

A rapid isolation method for E. coli Type I is being presented: A 4-6 hours resuscitation period at 24 +/- 3 degrees C is immediately followed by the 44 +/- 0.1 degrees C incubation period. Using this method the result can be read off after 24 hours, in exceptional cases after 48 hours. This technique enables the demonstration of an hygienic parameter important for food microbiology within a short time. Examinations will now be started in the Federal Health Office with the aim for defining E. coli-standards for various foods. It is planed to recommend these standards to the federal health authorities for including them in appropriate food regulations.

Docs get their way. Under AMA attack, feds back off antitrust enforcement.

Although the American Medical Association didn't win antitrust relief for doctors through federal legislation, the mere threat of a new law that would reduce federal agencies' authority appears to have resulted in a host of favorable legal rulings for physicians and implied promise of lenient enforcement in the future.

[Asthma and scuba diving Absolute contraindication? in all asthma patients?].

Physical and psychological fitness are required for scuba diving, leading to medical contraindications in certain subjects. Asthma, a condition exhibiting increasing prevalence in the general population is currently considered an absolute contraindication for scuba diving by the French Federation for Submarine Sports and Education (FFESSM). There is however no documented evidence demonstrating a higher risk in asthmatic divers. Our English-speaking colleagues have suggested that certain asthmatic subjects could participate in scuba diving sports under certain conditions without any higher risk compared with non-asthmatic divers. We recall here the impact of diving on respiratory function and potential consequences in asthmatic subjects, proposing that the formal contraindication against scuba diving should be maintained for asthmatic patients who experience frequent symptoms (step 2 or more of the International Consensus Report on Diagnosis and Treatment of Asthma) and/or have a baseline obstructive syndrome. It would appear reasonable to discuss the contraindication concerning patients with rare acute episodes and who have a perfectly normal respiratory function. The question of bronchodilator inhalation prior to diving may be a question to debate. However, such a proposal cannot be considered to be valid unless well-conducted studies of the clinical manifestations are available (frequency and severity of the acute episodes, triggering factors) for the diver candidate. Because of the highly restrictive nature of the contraindication notification and the absence of arguments backing up the decision, the question should be put to competent authorities (sports federations, learned societies) in order to ascertain the pathophysiological mechanisms involved and collect reliable epidemiological data before proposing a consensus discussion. This process may lead to the delivery of scuba diving authorizations for selected asthmatic subjects without a higher risk than non-asthmatic subjects.

Behavioral health and managed care contracting under SCHIP.

This Policy Brief examines behavioral health managed care contracting under separately administered State Children's Health Insurance Programs (SCHIP), i.e., programs that operate under the direct authority of Title XXI of the Social Security Act rather than as expansions of Medicaid. Most separate SCHIP programs buy managed care style health insurance for some or most of their enrolled children. Because Title XXI provides states with far greater administrative flexibility than Medicaid with respect to coverage and benefit design, provision of services, and administration of managed care arrangements,studying separate SCHIP managed care products sheds important light on how states might approach insurance and managed care design generally in the area of behavioral health were Medicaid modified through section 1115 demonstration or federal statutory authority to permit greater latitude. To conduct this analysis, two nationwide databases maintained by the George Washington University Center for Health Services Research and Policy (CHSRP) were used: a database consisting of all Medicaid MCO-style managed care contracts in use in Calendar Year 2000; and a nationwide database consisting of contracts used by separate SCHIP programs for the same calendar year. As of the point of collection in 2000 there were 33 such separate programs; according to CMS' latest website information, that total has now reached 35. Both sets of contracts were analyzed and separated into their components by lawyers experienced in managed care contract analysis and interpretation. The data were entered into working tables that organize the contents of the contracts into a series of searchable domains.

Exemption of certain research and demonstration projects from regulations for protection of human research subjects--DHHS. Notice of proposed rulemaking.

The Department of Health and Human Services (the Department or HHS) is proposing to include among the types of research specifically exempt from the application of the regulatory requirements of 45 CFR Part 46 (protection of human research subjects), research and demonstration projects conducted under the Social Security Act and other Federal statutory authority and designed to study certain public benefit or service programs, the procedures for obtaining benefits or services under those programs, and possible changes or alternatives to those programs or procedures, including changes in methods or levels of payment. This proposed amendment to the revised final regulations for protection of human research subjects (published January 26, 1981) would, in effect, restore to the regulations an exemption included in the initial notice of proposed rulemaking (NPRM) (published August 14, 1979). These demonstration and service projects are already subject to procedures which provide for extensive review by high level officials in various program administration offices. Review by an IRB would be duplicative and burdensome to state and local agencies and to other entities participating in demonstration projects. Removal of an unnecessary layer of review will not only reduce the cost of the projects but help to avoid unnecessary delays in project implementation.

Diagnostic relevance of the determination of lymphocyte subpopulations in environmental medicine.

Earlier hopes that determination of lymphocyte subpopulations might become a strong diagnostic tool in environmental medicine have not been fulfilled in recent years. Analysis of the scientific literature rather shows that there are only few examples for environmental exposures causing reproducible shifts of lymphocyte subpopulations. Moreover, current knowledge suggests that "environmental diseases" are not associated with characteristic changes of subpopulation patterns. If lymphocyte subpopulations are analyzed, each diagnostic step, including indication, sample handling, analytic procedure and data-interpretation, should adhere to good quality criteria. Taking all together, the determination of lymphocyte subpopulations in the context of environmental medicine comes under category IV of the criteria of the Commission for Methods and Quality Assurance in Environmental Medicine of the German federal health authority (Robert Koch-Institute; RKI): "A procedure cannot be recommended because there is not sufficient information to justify it" (here: no solid trends in epidemiological examinations), "and because theoretical considerations speak against an application" (here: high physiological variability and missing exposure or substance specificity).

Protecting the privacy of third-party information: recommendations for social and behavioral health researchers.

In psychosocial and health-behavioral research, we often request that research participants provide information on significant individuals in their lives, so-called "third parties". Recently there has been a greater recognition of privacy issues and risks in research pertaining to third parties. Reaction on the part of USA federal regulatory authorities to one study [Amber, D. (2000). Case at vcu bring ethics to forefront. , 14, 1], which attempted to collect survey data about the psychiatric history of respondents' parents, has generated such concern and caution that longstanding practices for the collection of social determinants of health data are being questioned and are at risk of being disallowed by Institutional Review Boards (IRBs). In this paper, we consider third party research rights and risks from the perspective of social and behavioral scientists. Focusing on research about health and quality of life, we first discuss the rationale for research methods that elicit contextual information about family members, friends, co-workers, and other social contacts. Second, we discuss the matter of 'privacy' and its central role in the current third party rights and risks dialogue. Next, we describe ways to effectively manage third-party information, building upon current recommendations by the Office for Human Research Protections (OHRP) and Botkin's [(2001). Protecting the privacy of family members in survey and pedigree research. Journal of the American Medical Association, 285(2), 207-211] treatment of the matter for survey and pedigree research. Lastly, we discuss the implications of applying these data collection and management strategies in social and behavioral research. We assert that these recommendations protect the rights of, and minimize the risks to, third parties without impeding social and behavioral health research.

Panax ginseng pharmacology: a nitric oxide link?

Panax ginseng is used in traditional Chinese medicine to enhance stamina and capacity to cope with fatigue and physical stress. Major active components are the ginsenosides, which are mainly triterpenoid dammarane derivatives. The mechanisms of ginseng actions remain unclear, although there is an extensive literature that deals with effects on the CNS (memory, learning, and behavior), neuroendocrine function, carbohydrate and lipid metabolism, immune function, and the cardiovascular system. Reports are often contradictory, perhaps because the ginsenoside content of ginseng root or root extracts can differ, depending on the method of extraction, subsequent treatment, or even the season of its collection. Therefore, use of standardized, authentic ginseng root both in research and by the public is to be advocated. Several recent studies have suggested that the antioxidant and organ-protective actions of ginseng are linked to enhanced nitric oxide (NO) synthesis in endothelium of lung, heart, and kidney and in the corpus cavernosum. Enhanced NO synthesis thus could contribute to ginseng-associated vasodilatation and perhaps also to an aphrodisiac action of the root. Ginseng is sold in the U.S. as a food additive and thus need not meet specific safety and efficacy requirements of the Food and Drug Administration. Currently, such sales amount to over $300 million annually. As public use of ginseng continues to grow, it is important for this industry and Federal regulatory authorities to encourage efforts to study the efficacy of ginseng in humans by means of appropriately designed double-blind clinical studies.

The use of granulocyte-macrophage colony-stimulating factor to enhance hematologic parameters of patients with cirrhosis and hypersplenism.

In patients with end-stage liver disease complicated with hypersplenism, neutropenia and thrombocytopenia are risk factors for systemic sepsis and spontaneous bleeding. Granulocyte-macrophage colony-stimulating factor is a naturally occurring cytokine that promotes proliferation and differentiation of granulocyte and monocyte progeny cells. In addition, it is reported to promote the proliferation of megakaryocytes. Its use as an intravenous infusion is Federal Drug Authority (USA) approved for the enhancement of myeloid recovery following autologous bone-marrow transplantation. The present study was initiated to determine whether granulocyte-macrophage colony-stimulating factor could be used to increase the white blood cell and platelet count in patients with cirrhosis and hypersplenism and to determine whether the more convenient subcutaneous route can be used with the same efficacy as the recommended intravenous route. Nine patients with cirrhosis and hypersplenism manifested by a reduced absolute neutrophil count (mean value of 1300 +/- 200/mm3) were studied. In eight patients, Indium white blood cell splenic sequestration scans were obtained before and after the administration of granulocyte-macrophage colony-stimulating factor intravenous infusion or subcutaneously for 7 days. One patient had to discontinue the therapy due to a reaction to granulocyte-macrophage colony-stimulating factor. Following intravenous infusion of granulocyte-macrophage colony-stimulating factor, the mean absolute neutrophil count increased to 2600 +/- 1100/mm3. Following subcutaneous administration, the mean absolute neutrophil count increased to 4100 +/- 200/mm3. No significant change in platelet count occurred with either route of administration. Indium scans obtained before and after the treatment period revealed no significant difference in the splenic uptake.(ABSTRACT TRUNCATED AT 250 WORDS)

[The current status of neuropathology in the Federal Republic of Germany 1979 (author's transl)].

This article describes changes in neuropathologic work towards a more intravital diagnostic aid, the increase in university neuropathologic departments, and the increased amount of neuropathology in teaching and examinations. These positive developments contrast with some genuine problems: the clinically oriented departments of neuropathology in some big research centers have been closed or altered and the personal staff of the university departments has been reduced. Subspeciality training in neuropathology within pathology should be supplemented by the possibility of entering neuropathology by way of neurology and psychiatry. Neuropathology should be connected to the neurosciences since this is the prerequisite to attain and maintain international research standards. However, the conditions necessary to achieve this aim personally and institutionally should be made available to all pathologists, clinicians, and administrators concerned with this subject.

[Occupationally-induced risk of HIV infection in medical personnel].

Since hepatitis-B immune prophylaxis is possible, HIV infection could become the most important risk of infection facing medical personnel. Today, it must be assumed that HIV infection almost always leads to the fatal disease AIDS. The principal source of infection for medical personnel is patients' blood. The disease is usually transmitted parenterally, as a result of inoculation by a needle prick or similar injury. Blood contact with non-intact skin or mucosae can also lead to infection. In prospective studies, HIV infection was found in approximately 0.5% of cases following needle-prick injuries with anti-HIV-positive blood. The HIV infection risk for medical personnel thus ultimately depends on the frequency of needle prick-type injuries and the number of anti-HIV-positive patients. Assuming that there are 50,000-100,000 anti-HIV-positive persons in the Federal Republic of Germany (Federal Health Authority estimate) the occupational risk to the life of a surgeon sustaining 40 injuries per year could be over 1%. In densely-populated areas with above average contamination of patients a higher HIV infection risk must be expected. An increase in contamination in the next few years would also lead to an increased risk of infection.

The use of standardized extracts in allergen immunotherapy.

BACKGROUND: Double-blind, placebo-controlled studies have established that injection allergen immunotherapy is clinically effective. However, it is not known to what extent the doses of allergen extract commonly used in clinical practice match those that have been used in these controlled studies. OBJECTIVE: The aim of this study was to determine by questionnaire the doses of standardized allergen extracts commonly used by board-certified allergists in the United States and to compare these with doses that have proven effective in double-blind, placebo-controlled studies. METHODS: A questionnaire containing a hypothetical case and asking for a recommended allergen prescription for maintenance immunotherapy was mailed to 500 randomly selected board-certified members of the American Academy of Allergy, Asthma and Immunology living in the United States. The recommended doses were compared with those doses of the extracts that had been proven effective by using major allergen content figures for representative standardized US allergen extracts provided by an allergy extract laboratory. RESULTS: Responses were received from 118 (23%) of the addressees. Eighty (16%) contained interpretable data on maintenance dosing for extracts. The median doses of pollen recommended were comparable with those that have been demonstrated to be clinically effective. Median doses of house dust mites were only slightly lower than those that have proven effective. Median doses of animal dander, on the other hand, were well below those used effectively in controlled studies. Although the median doses used were often in the range of proven doses, the range of doses recommended by allergists included some that were one tenth to one five hundredth those of the median doses. CONCLUSION: In the absence of useful guidance from the federal regulatory authorities, American allergists, for the most part, use doses of pollens and house dust mites that are within the proven range. Their dosing of animal dander is generally below proven effective doses. There is, however, a wide range of dosing of all extracts used, and there is use of mixes that have no botanical basis. Therefore there is need for studies defining what are effective and ineffective allergen extract doses.

Acculturation attitudes and sociocultural adjustment of sojourner youth in Israel.

Among 300 Jewish sojourner youth (age range: 15-18 years) from the Russian Federation, the authors investigated associations of acculturation attitudes, measures of sociocultural adjustment, and length of the encounter with the host society, Israel. All the youth were participating in a 1-3-year program of high school studies in Israel. In the light of J. W. Berry's (1997) acculturation model, the authors examined the assumptions that the participants' adjustment to Israeli society would require readiness to abandon some of their previous identity and to adopt elements of a new identity characteristic of the host society. Lower degrees of separation and higher degrees of integration were positively linked with measures of sociocultural adjustment. The adjustment scores tended to decrease over time spent in Israel.

Report on the 2003 revision of the U.S. Standard Certificate of Death.

The National Center for Health Statistics (NCHS) is responsible for publishing Standard Certificates of Birth and Death for the United States of America. The standard certificates are revised roughly every 10 years. The revision process is designed to ensure that the standard certificates meet, as nearly as possible, the use for which they are intended at all levels: individual, local, state, and federal. The authors report on the most recent revision of the U.S. Standard Certificate of Death, recording the process and the role of the National Association of Medical Examiners in the process. Changes recommended during revision include requesting known aliases of a decedent and rearrangement of the certificate to provide more room for those items requesting dates and for describing how the injury occurred. New items have been added asking for information regarding traffic fatalities, the role of tobacco use in causing death, and whether female decedents were pregnant. Once approved by the Department of Health and Human Services, the new standard certificate will be made available to the states. Each state will have 2 years to adapt the U.S. Standard Certificate of Death to its use and to implement new state death certificates on January 1, 2003.
