Rey Auditory Verbal Learning Test performance of a Federal corrections sample with acquired immunodeficiency syndrome.

The Rey Auditory-Verbal Learning Test (AVLT) was administered to 30 inmates from three United States Federal corrections facilities. Fifteen were HIV seropositive and carried a diagnosis of AIDS; 15 were seronegative controls. The groups were comparable in age, education, sex, estimated premorbid IQ, and ethnic make-up. Both groups learned across trials, and produced similar acquisition curves. They also showed equivalent registration, but controls performed significantly better than subjects with AIDS on AVLT Trials II, IV, V, Recognition, and sum of I through V. AIDS subjects made significantly more intrusion errors than controls, suggesting that seropositive inmates performed more poorly, at least in part, because they experienced difficulty discriminating relevant from irrelevant responses during recall. Evaluation of serial position effects suggested that AIDS subjects experienced recall problems only with the middle segment of the word list. This finding may be unique to persons with AIDS and is consistent with the view that distinct clinical groups produce different recall patterns.

Secure bioinformatics: privacy-preserving federated analytics using homomorphic encryption.

MOTIVATION: Large-scale bioinformatics analyses increasingly require collaboration across multiple cohorts and institutions, yet existing workflows often rely on data co-localization, which is slow, difficult to scale, and raises privacy concerns. We present a privacy-preserving federated analytics framework that enables secure statistical analysis across distributed datasets without transferring raw data, by performing all computations on encrypted data via cryptographic methods. RESULTS: We evaluate the framework by validating polygenic risk scores and conducting meta-analyses on two real-world cohorts. The proposed solution achieves over 99.9% accuracy relative to plaintext analyses, while maintaining scalable runtime performance with increasing data size and number of participating sites. These results demonstrate the feasibility of secure federated analytics for practical bioinformatics applications involving sensitive data.

Ecological effects of home-based, school-based, and community-based training of parents of children with learning and behavior problems.

A federally funded three year project to train parents of children with learning and behavior problems is discussed in terms of its ecological impact on parents, their children, their children's teachers, and on the community at large. The design of the project including the home intervention component, the school-based support group component, and the community component is briefly detailed. A comprehensive analysis of data on the effects of the various parent training components on parent, teacher and student perceptions of each other, as well as on student achievement, attendance and self-concept measures are reported. Overall, the data demonstrate the success of the project and support the ecological premise that making changes in one system surrounding a troubled child causes resultant changes in other systems surrounding the child.

Learning disabilities in New Zealand: where kiwis and kids with LD can't fly.

Learning disabilities (LD) has never been officially recognized as a category of special education in New Zealand. This article discusses the main reasons for the rejection of the LD category. The education system in New Zealand is described, and the nature of special education is outlined to provide a context for considering LD. Attempts by the parent group SPELD (New Zealand Federation of Specific Learning Disabilities Associations) to have "specific learning disabilities" (SLD) recognized in legislation are discussed, along with reasons for the rejection of these attempts by state education officials. It is concluded that LD/SLD will never be recognized as such in New Zealand. The needs of students with LD may potentially be met by new policies for "high incidence" special needs. But teachers' lack of skills and strategies for working with a range of learning difficulties is seen as an impediment to students with LD being adequately helped in the foreseeable future.

Roles of the federal and state governments in outcomes assessment.

Both federal and state governments have mandates to collect, analyze, and disseminate health care information. The federal government is the single largest payer for health care and health services research. Its agencies, the Healthcare Finance Administration (HCFA) and the Agency for Healthcare Policy Research (AHCPR) play a major role in shaping information strategies for all health care stakeholders. State governments are among those stakeholders and are fertile grounds for experimentation, change, and learning. Building effective federal-state partnerships and public-private partnerships can help foster innovation in health data collection and analysis, as well as identify new strategies for information dissemination.

Successful control of epidemic diphtheria in the states of the Former Union of Soviet Socialist Republics: lessons learned.

Epidemic diphtheria reemerged in the Russian Federation in 1990 and spread to all Newly Independent States (NIS) and Baltic States by the end of 1994. Factors contributing to the epidemic included increased susceptibility of both children and adults, socioeconomic instability, population movement, deteriorating health infrastructure, initial shortages of vaccine, and delays in implementing control measures. In 1995, aggressive control strategies were implemented, and since then, all affected countries have reported decreases of diphtheria; however, continued efforts by national health authorities and international assistance are still needed. The legacy of this epidemic includes a reexamination of the global diphtheria control strategy, new laboratory techniques for diphtheria diagnosis and analysis, and a model for future public health emergencies in the successful collaboration of multiple international partners. The reemergence of diphtheria warns of an immediate threat of other epidemics in the NIS and Baltic States and a longer-term potential for the reemergence of vaccine-preventable diseases elsewhere. Continued investment in improved vaccines, control strategies, training, and laboratory techniques is needed.

The paradox of hunger and economic prosperity in America.

Within a period of twenty years, America discovered that many of its citizens were hungry, acted to greatly reduce this problem through an array of federal programs, and, in the 1980s, learned that hunger has reappeared in epidemic proportions. The return of hunger to the U.S. is associated with economic and tax policies that have reallocated income distribution from poor and middle-income groups to the wealthy, and with a corresponding failure to utilize the federal government to protect high-risk population groups from undernutrition associated with growing economic deprivation in the nation.

Marking progress toward service integration: learning to use evaluation to overcome barriers.

While federal statutes defining categorical programs and funding streams are most often cited as barriers to service integration efforts, there is evidence that service integration efforts are also being stymied by factors at the state and local levels as well. This case study examines five types of barriers to service integration that have been evident in Georgia's Family Connection and describes how an evaluation instrument and process was developed to assess progress toward service integration at the local level. The findings of a pilot study of the use of this instrument suggest that it can help to: (a) define starting points for service integration efforts; (b) identify specific service integration activities that are feasible in the context of a unique community; (c) specify the time needed to be allocated to service integration efforts; (d) identify the local costs and benefits of engaging in service integration; and (e) provide specifications for conducting a self-assessment of progress at the local level toward service integration goals.

Current medicolegal and confidentiality issues in large, multicenter research programs.

The convenience of fast computers and the Internet have encouraged large collaborative research efforts by allowing transfers of data from multiple sites to a single data repository; however, standards for managing data security are needed to protect the confidentiality of participants. Through Dartmouth Medical School, in 1996-1998, the authors conducted a medicolegal analysis of federal laws, state statutes, and institutional policies in eight states and three different types of health care settings, which are part of a breast cancer surveillance consortium contributing data electronically to a centralized data repository. They learned that a variety of state and federal laws are available to protect confidentiality of professional and lay research participants. The strongest protection available is the Federal Certificate of Confidentiality, which supersedes state statutory protection, has been tested in court, and extends protection from forced disclosure (in litigation) to health care providers as well as patients. This paper describes the careful planning necessary to ensure adequate legal protection and data security, which must include a comprehensive understanding of state and federal protections applicable to medical research. Researchers must also develop rules or guidelines to ensure appropriate collection, use, and sharing of data. Finally, systems for the storage of both paper and electronic records must be as secure as possible.

Assistive technology for postsecondary students with learning disabilities: an overview.

The number of postsecondary students with learning disabilities has increased dramatically over the last several years. This increase, coupled with federal legislation mandating "academic adjustments" for students with disabilities, has prompted the development of postsecondary learning disability support service programs. One support service that has begun to attract considerable attention is assistive technology. The purpose of this article is to provide an overview of assistive technology as it relates to postsecondary students with learning disabilities by (a) briefly tracing the development of assistive technology service for postsecondary students with learning disabilities; (b) identifying basic models of assistive technology service delivery and specific services; (c) providing a description of specific assistive technologies; (d) reviewing research on the effectiveness of assistive technology with postsecondary students with learning disabilities, with a focus on the authors' 3-year federally funded study; and (e) concluding with a summary and recommendations.

Challenges of establishing a nursing center in rural eastern Oregon.

The success of the center, in fact its very existence, is the result of cooperation among many persons and agencies. Financial gifts, loans and grants have given the clinic a three-year time period to learn valuable lessons on how to organize for self-sufficiency. Staff have learned how to market to increase patient visit and have obtained Federal Rural Health Clinic status which will increase revenues substantially. Nurse Practitioners are learning appropriate visit coding and hold regular brainstorming meetings to develop creative business opportunities to assure financial stability. As a result of these experiences, the NP faculty have been able to design learning experiences for the nurse practitioner students which introduce them to entrepreneurial realities. Challenges are being met by the NPs in this rural practice which require vigor, creativity, and vigilance. Once the center reaches the level of self-sufficiency, it is the intent of the community to build a facility which can support a significant increase in patient load and still have room for other social and health services to operate within the facility. Bridges to the medical community are being strengthened through better communication and more community involvement. Educating the public and the medical community about the role of nurse practitioners and the broad base of nursing centers is a continual challenge for both faculty and students at the School of Nursing.
