Planning a statewide genetic screening program: defining program functions to achieve desired outcomes.

When responsibility for administering the Genetic Screening Program in Georgia was transferred from an academic institution to state authority in 1982, the need was identified to reassess program planning. Accordingly, a cooperative effort was initiated between the Director of the Genetic Screening Program and representatives of the Centers for Disease Control to define desired program outcomes and the functions that should be performed to achieve these outcomes. This cooperative effort resulted in the development of specific and measurable outcomes for Georgia's Genetic Screening Program. These desired outcomes indicate the degree of reduction in morbidity and mortality associated with genetic diseases the Program is expected to achieve within a specified period of time. The major actions that should be taken to achieve these outcomes were also identified and delineated in sequence using flowchart format. These explicit descriptions of desired program outcomes and the functions necessary to achieve these outcomes provide the Genetic Screening Program Director with a valuable resource to use in planning program activities and assessing the extent to which the Program is successful in achieving its overall goal of reducing morbidity and mortality associated with genetic diseases.

Immunopharmacology of rapamycin.

The potent immunosuppressive drugs FK506 and rapamycin interfere with signal transduction pathways required for T cell activation and growth. The distinct inhibitory effects of these drugs on the T cell activation program are mediated through the formation of pharmacologically active complexes with members of a family of intracellular receptors termed the FK506 binding proteins (FKBPs). The FKBP12.FK506 complex specifically binds to and inhibits calcineurin, a signaling protein required for transcriptional activation of the interleukin (IL)-2 gene in response to T cell antigen receptor engagement. The FKBP12. rapamycin complex interacts with a recently defined target protein termed the mammalian target of rapamycin (mTOR). Accumulating data suggest that mTOR functions in a previously unrecognized signal transduction pathway required for the progression of IL-2-stimulated T cells from G1 into the S phase of the cell cycle. Here we review the immunopharmacology of rapamycin, with particular emphasis on the characterization of mTOR.

Obstetric early discharge versus traditional hospital stay.

Recent research and media reports have suggested that obstetric early discharge is not cost-effective for postnatal care in the Australian health care system, based on the work of the Centre for Health Economic Research and Evaluation. This is probably an erroneous conclusion because the centre excludes the important cost category of medical costs, and its conclusions depend on survey estimates of 'community costs' which are empirically of poor quality and theoretically of doubtful relevance to health care system decision-making. This study finds that obstetric early discharge is more cost-effective than a traditional hospital stay even when community costs are included; and highly cost-effective when considering health system costs alone. Further cost advantages are simulated by increasing obstetric early discharge program activity and reducing length of stay for both programs. Our results suggest that safe, cost-effective options for low-risk obstetric care deserve further investigation in Australia.

Effect of once-a-week training program on physical fitness and metabolic control in children with IDDM.

To examine whether a physical activity program could improve physical fitness and glycemic control, 32 children and adolescents with insulin-dependent diabetes mellitus (IDDM) were examined before the program and 3 mo later. Fifty percent of the subjects (n = 16) participated in the training for 1 h/wk (exercise group), whereas the remaining subjects were engaged in nonphysical activities for an equal amount of time (nonexercise group). Age of the subjects ranged from 8.2 to 16.9 yr, (mean 11.9 yr), with mean duration of diabetes 0.6-13.1 yr (5.2 yr). During the 3-mo program peak oxygen consumption (VO2) rose from 40.0 to 43.8 ml.min-1.m-2 (P less than .01) in the exercise group but only by 1.3 ml.min-1.m-2 in the nonexercise group (NS). Metabolic control did not improve in either group, with glycosylated hemoglobin level rising from 9.8 to 10.5% (P less than .01) in the exercise group and from 9.4 to 9.7% (NS) in the control group. When subjects were stratified according to their participation, metabolic control was significantly better among diabetic subjects participating frequently (greater than or equal to 11 of 13 sessions) than among those participating infrequently (less than 11 of 13 sessions), regardless of the type of activity. It was concluded that a training program of 1 h/wk for 3 mo does improve physical fitness but not the metabolic control of diabetes. On the other hand, glycemic control appears to be best among diabetic subjects who are motivated to participate in any kind of program related to the treatment of their disease.

Social activation of the elderly. A social experiment.

Social isolation and understimulation are considered to be major problems among institutionalized aged. This article describes an 'activation' program for elderly people living in a senior citizen apartment building. The intention of the research team was to devise a program together with the elderly and the staff, the goals being to increase social activation and self-dependence among the elderly. The program devised was implemented within the apartment's existing financial framework, involving no additional costs, overtime work or external resources. The program was designed in such a way as to allow for measurement of social activation in both the experimental and control groups. This report focuses primarily on the problems which arose in the personnel group in conjunction with the program. Evaluation of these problems was carried out by means of tape-recorded personnel meetings. This paper presents the analysis of these recordings. It was of major importance to the program that any organizational changes be enacted only on the initiative of the elderly and the staff themselves. The results show that it is possible, with relatively simple and inexpensive methods, to stimulate the elderly's interests and counteract social isolation and understimulation.

Cost containment education efforts in United States medical schools.

Noting the increasing nationwide concern with factors relating to rising health care costs, the Association of American Medical Colleges surveyed 119 U.S. medical schools in the summer of 1978 to ascertain the degree of program activity in the area of cost containment education. A 100 percent response was achieved. An analysis of this data indicates that considerable activity is underway. Forty-one institutions (34 percent) have programs underway or planned specifically to teach health care cost containment to undergraduate medical students or residents or both. The majority of such programs were introduced during the past two years. The costs of such programs are fairly modest, averaging $22,680 per year. Respondents indicated that further activities might be enhanced by development of a primer for faculty and students on elements of cost containment education and the organization of a series of regional workshops related to this subject.

Disrupted mitochondrial electron transport function increases expression of anti-apoptotic bcl-2 and bcl-X(L) proteins in SH-SY5Y neuroblastoma and in Parkinson disease cybrid cells through oxidative stress.

Death of dopamine neurons in Parkinson disease (PD) may arise from consequences of the complex I (C-I) defect in the mitochondrial electron transport chain (ETC). Whether cells activate programmed death (apoptosis) pathways derives, in part, from relative activities of proteins such as bcl-2 and bcl-X(L), that have anti-apoptotic actions. We studied the responses of bcl-2 and bcl-X(L) genes in pharmacologic (acute incubation with methylpyridinium (MPP+)) and mitochondrial transgenic ("cybrid") models of Parkinson disease C-I defects. MPP+ incubation increased levels of bcl-2 and bcl-X(L) proteins in native SH-SY5Y cells but not in rho(0) cells devoid of ETC activity. MPP+ increased bcl-2 mRNA levels by 40% at 8 hr. Confocal microscopic imaging showed that the intracellular distribution of immunoreactive bcl-2 was not significantly associated with mitochondrial membranes at baseline but was associated with mitochondria after 12 hr of MPP+. Immunoreactive bcl-X(L) protein was significantly and equally associated with mitochondrial membranes both at baseline and after MPP+. PD cybrids showed increased basal levels of bcl-2 and bcl-X(L) proteins, similar to the maximum levels found after MPP+ treatment of control SY5Y cells. After MPP+ exposure, bcl-2 protein levels increased in control cybrids but did not increase further in PD cybrids. Both pharmacologically generated and transgenically induced C-I inhibition increases levels of anti-apoptotic bcl proteins, possibly from increased gene transcription. Augmentation of bcl-2 and bcl-X(L) expression may delay neurodegeneration in PD.

Issues in estimating the cost of innovative mental health programs.

This paper reviews problems encountered in estimating the unit cost of services provided by innovative mental health programs and illustrates methods for addressing these problems. Generally, the cost of a health care service is determined by identifying all resources used in its production and the cost of those resources. These costs are divided by appropriate workload measures to determine the cost per unit of service or per client. Issues that must be addressed include: 1) direct program costs; 2) indirect costs (including administration and capital costs); 3) program resources used to support research and other non-program activities; and 4) identification of "typical" workloads as the program is implemented. Application of these methods is illustrated with data from a multi-site study of intensive psychiatric community care conducted at nine Department of Veterans Affairs Medical Centers in the Northeast. A sensitivity analysis revealed that estimates of program costs vary by 59% over the entire program, and from 17%-168% at individual sites, depending on which cost estimation methods were included. The average cost of case management in this program varied considerably across sites, primarily reflecting differences in caseload size and staffing levels. Adjusting for inflation, the cost of this program falls below the cost of other published intensive community programs.

Faculty development: a field of dreams.

This chapter describes the faculty development efforts of the eight schools that participated in The Robert Wood Johnson Foundation's "Preparing Physicians for the Future: Program in Medical Education." The authors define "faculty development" as the "enhancement of educational knowledge and skill of faculty members so that their educational contributions can extend to advancing the educational program rather than just teaching within it." Faculty development programs varied widely among the schools. Some schools had active programs in place, others initiated programs at the start of the project. This chapter explores the faculty development topics and methods, both shared and unique, among the eight schools. It then looks at the ways the schools motivated their faculties to participate in their programs. Finally, it describes some of the outcome measures that were used to gauge the effectiveness of the faculty development programs. The authors conclude that the eight schools' approaches and levels of commitment to their faculty development programs varied. They present lessons learned from the successes and failures of the various programs.

Bone marrow transplantation at the University of Nebraska Medical Center.

The bone marrow transplant program at UNMC is currently one of the most active programs in the country. The benefits to patients who are cured of disease by transplantation cannot be measured. The large volume of clinical and basic science research related to transplantation has enhanced the academic stature of UNMC. The combination of patient care, education, clinical research, and basic science research provides an excellent model for the operation of an academic medical institution.

Oligonucleotides induce apoptosis restricted to the t(14;18) DHL-4 cell line.

Most human follicular B-cell lymphomas are associated with t(14;18) chromosome translocation that joins the bcl-2 gene with the IgH locus. This hybrid gene causes upregulation of BCL-2 protein expression, endowing cells with survival advantage. Although early BCL-2 overexpression is definitely responsible for immortalization/transformation, its exact role in the overt transformation as well as in the maintenance of the tumor phenotype is not known. The capacity of oligodeoxynucleotides (ODN) to modulate gene expression specifically has been exploited to downregulate the overexpression of BCL-2 protein in the SU-DHL-4 human follicular B-cell lymphoma line by the use of sense ODN or antisense ODN or antisense ODN designed to encompass the unique nucleotide sequence in the fusion region of the hybrid transcript. The specific downregulation of the bcl-2 transcript and of the relevant BCL-2 protein in the treated cells activated programed cell death and inhibited growing cells. The antitumor activity was restricted to the DHL-4 cell line carrying the specific nucleotide sequence at the bcl-2/IgH joining region. Thus, DHL-4 lymphoma cells derived from the acute phase of human follicular B-cell lymphoma, although endowed with additional activated oncogenes, were growth inhibited by bcl-2 downregulation with additional activated oncogenes, were growth inhibited by bcl-2 downregulation in a genetically restricted fashion. The biological activity was exerted exclusively by ODNs synthesized in the sense orientation. The sense ODNs have been proposed to anneal the hybrid bcl-2/IgH antisense RNA as identified in this study.

Dynamic systems-modeling as a means to estimate community-based prevention effects.

The best applications of prevention programming now are believed to be community-supported strategies, comprehensive in scope, implemented in stages, and delivered by public and private agencies and organizations. Despite the flurry of program activity, research directed toward comprehensive, community-based prevention programming remains a largely uncharted domain. Communities need to know what will work-in their specific contexts. The essential question communities are asking themselves and consultants is, "Which mix of interventions will yield maximum reduction in alcohol and other drug (AOD) abuse in our community?" Computer-based dynamic simulation modeling holds promise in helping provide an answer to this question. These models are designed to replicate the historic patterns and dynamics of target communities with regard to substance availability, use, and misuse and then to simulate future patterns and dynamics under alternative assumptions and intervention mixes. Researchers can use these models to construct structural relationships that reflect alternative theories or explanations for important processes. The models afford community planners and decision-makers with mechanisms for asking "what if" questions regarding alternative intervention mixes and, consequently, for determining which politically acceptable mix of feasible interventions will yield the most reduction in AOD-related problem behaviors. In this chapter, a model under development by the Prevention Research Center of the Pacific Institute for Research and Evaluation is described that focuses on alcohol use and misuse in communities and allows the testing of a wide range of prevention options.

The Alaska Native diabetes program.

OBJECTIVES: To provide optimum health care to indigenous people with diabetes, to prevent diabetes, and to monitor the epidemiology of diabetes and selected complications. The purposes of this paper are to describe the program and to present data that highlights the major problems and successes. STUDY DESIGN: Descriptive epidemiology report of diabetes and population service program based on yearly chart review data. METHODS: Almost half of Alaska Natives with diabetes have no direct access to physicians or hospitals. Health care delivery is now managed by the tribes themselves. Program emphases include maintenance of a population-based registry, formal training for village health aides, physical activity programs, patient education, primary prevention activities and adherence to standards of care to prevent complications. A centralized registry is maintained to assure that epidemiological data is available and patients are not lost to follow-up. Each year a random sample of charts at each major facility is audited against nationally standardized care guidelines. RESULTS: The prevalence of diabetes among Alaska Natives increased 80% over the 13 years from 1985 to 1998 (15.7/1000 to 28.3/1000, age adjusted to U.S. 1980 population). For the years 1986-1998 the incidence rates of lower extremity amputation and end stage renal disease were 6.1/1000 and 2.0/1000 respectively. The level of care provided to Alaska Native patients is comparable to that provided to the general diabetic patient population seen in Alaskan urban clinics. CONCLUSIONS: In spite of logistic challenges, care provided to Alaska Native people with diabetes compares favorably to that provided in other settings. Incidence rates of lower extremity amputation and end stage renal disease also remain comparable to or lower than those in other U.S. populations. Many aspects of our system could be extended to other chronic disease programs serving isolated indigenous populations. Primary prevention of diabetes remains a major challenge as life styles change.

[Pediatric medical emergencies: clinical classification on basis of severity of illness, distribution between work days and non-working days].

OBJECTIVES: Assess one year of activity in a pediatric medical emergency unit of a non-university hospital to detail the degree of gravity of patients admitted to pediatric wards and the distribution of non-programmed activity between and work days and non-work days. METHODS: Prospective classification into 5 degrees of emergency of all admitted children and count of non-programmed medical and surgical activity. RESULTS: A significantly growing number of consultations for minor problems was observed during non-work days. Most hospitalizations were for problems of a rather relative emergency nature. CONCLUSION: The creation of a "day-hospital" would allow evaluation and/or treatment of a large number of pediatric patients without requiring hospitalization. The problem of controlling the flow of consultations to the hospital remains a difficult problem. The many reasons leading to hospital consultation are poorly assessed. It appears indispensable to promote population "education" and development of closer physician's office-hospital collaboration.

Gender differences in physical activity and determinants of physical activity in rural fifth grade children.

This study determined if gender differences in physical activity could be accounted for by differences in selected social-cognitive determinants of activity behavior. Some 334 fifth grade, predominantly African-American students provided information regarding after-school physical activity and the hypothesized determinants of activity behavior. Boys reported significantly greater participation in vigorous ( > or = 6 METs) and in moderate to vigorous ( > or = 4 METs). Relative to girls, boys demonstrated higher levels of physical fitness, greater self-efficacy in overcoming barriers to physical activity, greater amounts of television watching, and higher levels of participation in community sports and physical activity organizations. When mean physical activity scores for girls and boys were adjusted for the effects of these determinant variables, the significant gender difference in physical activity remained. However, adjustment for self-efficacy in overcoming barriers and community sports reduced the gender gap by 5% and 7%, respectively. In contrast, adjustment for television watching increased the gender gap by about 8%. Results indicated perceived confidence in overcoming barriers to physical activity and participation in community physical activity programs are factors related to the gender difference in physical activity.

The public health perspective in health promotion and disability prevention for older adults: the role of the Centers for Disease Control and Prevention.

As the United States federal public health agency, the role of the Centers for Disease Control and Prevention (CDC) in health promotion and disability prevention with older adults encompasses research, surveillance and program activities in aging. This article characterizes the objectives and context of prevention in later life and summarizes CDCs functions, collaborative partnerships with public health agencies and other organizations, and range of activities in older adult health. As a major focus of these efforts, chronic disease risk reduction is examined through CDC's efforts in the area of physical activity; a longitudinal investigation of osteoarthritis in an older biracial rural population; and chronic illness self-management programs as a prototype for secondary prevention. Other CDC activities highlighted include addressing the burden of vaccine-preventable diseases through CDC-funded programs to improve immunization coverage in older adults, and falls prevention interventions and resources. Future directions in aging at CDC are also outlined.
