[Health technology in Mexico].

The features of the health technology cycle are presented, and the effects of the demographic, epidemiologic and economic transition on the health technology demand in Mexico are discussed. The main problems of science and technology in the context of a decreasing scientific and technological activity due to the economic crisis and the adjustment policies are also analyzed: administrative and planning problems, low impact of scientific production, limitations of the Mexican private sector, and the obstacles for technology assessment. Finally, this paper also discusses the main support strategies for science and technology implemented by the Mexican government during the 1980s and the challenges and opportunities that lie ahead.

Chemical carcinogens: a review of the science and its associated principles. U.S. Interagency Staff Group on Carcinogens.

In order to articulate a view of chemical carcinogenesis that scientists generally hold in common today and to draw upon this understanding to compose guiding principles that can be used as a bases for the efforts of the regulatory agencies to establish guidelines for assessing carcinogenic risk to meet the specific requirements of the legislative acts they are charged to implement, the Office of Science and Technology Policy, Executive Office, the White House drew on the expertise of a number of regulatory agencies to elucidate present scientific views in critical areas of the major disciplines important to the process of risk assessment. The document is composed of two major sections, Principles and the State-of-the-Science. The latter consists of subsections on the mechanisms of carcinogenesis, short-term and long-term testing, and epidemiology, which are important components in the risk assessment step of hazard identification. These subsections are followed by one on exposure assessment, and a final section which includes analyses of dose-response (hazard) assessment and risk characterization. The principles are derived from considerations in each of the subsections. Because of present gaps in understanding, the principles contain judgmental (science policy) decisions on major unresolved issues as well as statements of what is generally accepted as fact. These judgments are basically assumptions which are responsible for much of the uncertainty in the process of risk assessment. There was an attempt to clearly distinguish policy and fact. The subsections of the State-of-the-Science portion provide the underlying support to the principles articulated, and to read the "Principles" section without a full appreciation of the State-of-the-Science section is to invite oversimplification and misinterpretation. Finally, suggestions are made for future research efforts which will improve the process of risk assessment.

Analytical method comparison based upon statistical power calculations.

Testing for the equivalence of results generated by different analytical methodology is a common practice in the pharmaceutical sciences. Methodology changes are implemented for both scientific and economic reasons during a scientific study. Thus, the need to demonstrate the appropriateness of considering data generated by distinct methods as part of a single information population arises. This paper describes a rapid and simple approach to the statistical design and interpretation of method comparison experiments. The approach presented is based upon a statistical power calculation technique, a knowledge of the variability associated with the methods to be compared and the criteria for equivalence (the limits within which differences become immeasurable or, for practical purposes, insignificant). Reference tables are included which show necessary sample sizes for comparison experiments for common combinations of these three variables.

Systematic serials selection analysis in a small academic health sciences library.

This paper describes the implementation of a straightforward quantitative technique to analyze the serials collection of the Medical Library at the University of Missouri-Kansas City (UMKC). Our simplified operations research approach resulted in a savings of nearly $1400 per year in subscriptions costs without reducing the net number of seven hundred titles or causing an imbalance in the subject distribution of our collection. By detailing both the rationale behind the process and the actual steps followed at UMKC, we hope to demonstrate that operations research techniques can be used practically and successfully even in small health sciences libraries. In the Appendix a more general and more rigorous operations research approach to the analysis of serials collections is also presented in a fashion that is, as far as possible, not mathematically forbidding.

Deimplementation of inappropriate feeding practices in early care and education: a Hybrid Type 3 cluster-randomized trial.

BACKGROUND: The science of deimplementation-reducing harmful or ineffective practices-has focused almost exclusively on clinical prescribing, with no studies conducted in community or educational settings. Early care and education (ECE) settings offer a strategic venue for shaping eating behaviors, with children consuming up to 500 meals annually in these environments. However, ECE educators routinely use feeding practices that undermine self-regulation, including pressuring children to eat, rushing mealtimes, and offering food as reward. These practices contribute to food aversions, diminished self-regulation, and obesity risk. METHODS: We will conduct a Hybrid Type 3 cluster-randomized trial evaluating a co-designed deimplementation strategy package (WISE Words) across 88 ECE sites in Arkansas and Louisiana. Sites will be randomized 1:1 to WISE Words or usual practice, with usual practice sites receiving the intervention after two years (waitlist design). WISE Words includes six strategies: dynamic training using improvisation methods, peer learning collaboratives with goal setting, external facilitation, audit and feedback, environmental reminders, and tailored educational materials. The primary outcome is de-adoption of inappropriate feeding practices measured via direct mealtime observation (Table Talk). Secondary outcomes include adoption of evidence-based practices, acceptability, appropriateness, and sustainability at 12- and 24-months post-intervention. Child outcomes include Body Mass Index, skin carotenoid levels (Veggie Meter) willingness to try new foods (observed) and food neophobia (teacher and caregiver report). An explanatory sequential mixed methods design will test mechanisms of change derived from the Implementation Trust Building Theory of Change examining whether trust mediates strategy effects on outcomes. DISCUSSION: This trial extends deimplementation science into community settings by targeting culturally embedded behavioral practices rather than clinical prescribing behaviors. Results will inform approaches to shifting entrenched practices in ECE and similar settings while testing trust as a deimplementation mechanism. Sustainability assessments will address a notable gap, as few studies have examined whether deimplementation effects persist. TRIAL REGISTRATION: NCT07101321, July 20, 2025.

Basic science conferences in residency training: a national survey.

Basic science teaching is an important component of dermatology residency training, and the basic science conference is the major tool utilized by departments of dermatology for its implementation. To characterize the role of basic science conferences in dermatology training, a national survey of chief residents was conducted. Although the survey confirmed that a high value is placed on basic science conferences, a surprising finding was a significant level of dissatisfaction among chief residents, particularly those from university-based programs. Results of the survey have been used to redefine our own objectives in basic science teaching and to propose elements of methodology and curriculum.

Evaluation of public health science in the graduate community health nursing curriculum.

The purpose of this article is to describe and evaluate a unique course in Public Health Science that has recently been implemented in our College of Nursing. This course seeks to provide a synthesis of public health and nursing. The course description as well as the course objectives are outlined. A 22-item questionnaire was developed to obtain demographic information regarding the students enrolled in the course, their community health experience prior to entering the graduate program, their clinical area of specialization, reasons for enrollment in the course, strengths and weaknesses of the course, the degree to which the course met the objectives, and recommendations for future courses in Public Health Science. The findings suggest that the content of Public Health Science has been integrated into the graduate community health nursing program with much success.

The creation and early implementation of a high speed fiber optic network for a university health sciences center.

In late 1989 the University of Missouri Health Sciences Center began the process of creating an extensive fiber optic network throughout its facilities, with the intent to provide networked computer access to anyone in the Center desiring such access, regardless of geographic location or organizational affiliation. A committee representing all disciplines within the Center produced and, in conjunction with independent consultants, approved a comprehensive design for the network. Installation of network backbone components commenced in the second half of 1990 and was completed in early 1991. As the network entered its initial phases of operation, the first realities of this important new resource began to manifest themselves as enhanced functional capacity in the Health Sciences Center. This paper describes the development of the network, with emphasis on its design criteria, installation, early operation, and management. Also included are discussions on its organizational impact and its evolving significance as a medical community resource.

Identifying and Prioritizing Core Components of Relationship Education Programs: a Case Study of an Artificial Intelligence (AI) Assisted Systematic Review.

The field of prevention science seeks to identify and implement effective strategies to address social, emotional, and health challenges. A critical aspect of this endeavor is determining the core components of prevention programs that drive positive outcomes. This article presents a case study utilizing artificial intelligence (AI)-assisted systematic review methods to identify key components of healthy marriage and relationship education programs. Given the growing body of research in this domain, AI tools offer a promising means to enhance the efficiency and accuracy of literature reviews. This study employed AI to screen, code, and validate research articles, demonstrating its effectiveness in expediting systematic reviews while maintaining high accuracy in inclusion screening. This case study involved a systematic review of 22,028 resources (identified from PsycINFO, Academic Search Ultimate, and Google) and a final data set of 268 relevant studies. AI screening was integral in effectively conducting multiple rounds of screening. However, findings also highlight challenges in AI-assisted qualitative data abstraction, underscoring the continued need for human expertise in complex coding tasks. The study contributes to the ongoing discourse on integrating AI into prevention science methodologies and offers insights for optimizing AI applications in systematic reviews.

Nurses' perception of their psychological role in treating rehabilitation patients: a study employing the critical incident technique.

This study presents the theoretical literature on the psychological role of nurses. The nurses' perception of their psychological role is empirically obtained, employing the critical incident technique. General aims and objectives of pschological care of physically ill patients are formulated and are found to generally support the theoretical literature. Nurses were clearly found to perceive their psychological role as covering a very broad spectrum, the ultimate of which was the ability to anticipate and meet the emotional needs of the patient. The importance of implementing the application of social science concepts and methods to nursing is discussed.

Transfer of innovation for advancement in dentistry: a case study on pit and fissure sealants' use in Japan.

The implementation of scientific innovations is most important in advancing both dental care systems and dental science. However, scientific knowledge in dentistry is not always well implemented. In this paper the phases of development, diffusion, adoption and utilization of sealants are examined as one example of the way in which a relatively new innovation still needs more effort to ensure its wider use. Discussions with a dental manufacturer on the development of sealant materials and an investigation into the adoption of sealants in the national health insurance system of Japan were undertaken. Questionnaires regarding the education on sealants offered in dental schools and dental hygienist schools, and questionnaires to dental practitioners concerning their use of sealants, were used and analysed. The analysis of the various factors showed that the transfer of knowledge through the educational system is the most significant step in the uptake of innovations. Legality, insurance coverage and patient acceptance are significantly associated with the phase of adoption. A model of transfer pathways for new dental innovations is proposed.

[The integration of the behavioral sciences and biomedicine: the need for a metatheory].

Theoretical tensions and difficulties in the implementation of the biopsychosocial approach in health care uncover a problematic relationship between biomedicine and the behavioral sciences. The different professionals involved (e.g., psychologists and physicians) can interact through competition, collaboration, and integration and may be considered to represent health care subsystems, defined by profiles of their access to primary and secondary resources. Traditional institutionalization assigns the physician the hegemony in the system. Current challenges to this view underscore the need for a conceptual reformulation which should not only integrate--in a dialectical and complementary way--the contribution of physicians and other professionals, but also explicitly incorporate ethical and epistemological aspects derived from their relationship. Along with indications about the roles of metatheory, its relevance in the Latin American context is indicated.

Reorganization of a burn unit in response to underutilization: a critical assessment.

The incidence of burn injury in the United States has declined over the past few years, resulting in a dramatic decrease in the number of admissions to burn centers. This decrease has generated considerable concern, leading to a variety of proposals to modify burn units to control the cost of inpatient care. In 1986 Albany Medical Center Hospital, a 654-bed regional academic health sciences center, closed its burn unit and implemented a program to manage thermally injured patients in the intensive and progressive care areas of the medical center. A retrospective study was performed to compare patient outcomes and length of stay for the dedicated burn unit and the integrated burn program. Between the year before and the year after this change there was no significant difference in mortality rate, length of stay, or number of positive blood cultures. The relationship between burn severity and length of stay was unaltered by the burn program change. A comparison of data collected just after the change to those collected 2 years later again showed no difference, except that the annual census had dropped more than 50%. The results suggest that burn units can be converted to integrated burn programs without compromising patient care outcomes, although the lack of a cohesive burn team and the unavailability of beds designated for patients with burns ultimately resulted in a deemphasis of the burn program and consequent marked reduction in the number of patients with burns seen in the institution.

[The development, transfer and use of medical technology as a special subject of research].

Regardless of the real exposion of scientific findings and information concerning medical sciences, research in the field, especially fundamental one, has rather insignificant influence on the development of new technologies, applicable in everyday medical practice (pull technologies). Far greater significance has been put on research in other fields, usually initiated with other purposes. "Side product" of that research is the development of these technologies which are best applicable in medicine (push-technologies). This is not the only reason why, as a rule, there is no direct connection between researchers and those supposed to apply and use new technologies. Initiation of evaluational research in the field of medical technologies will be the only way to establish the relationship between the two groups of actors: researchers and implementators.

Providing access to blacks and Hispanics in dietetics education.

To increase the number of blacks and Hispanics in dietetics and three other health professions, the Health Sciences Recruitment and Retention Program was developed and implemented in 1985 by the College of Health at Florida International University in Miami. The coordinated undergraduate program assisted in a federal grant to accomplish the objectives of recruiting and retaining minority students. High school and community college students were recruited using a slide/tape presentation featuring black and Hispanic professionals. In addition, the college offered a summer course entitled "Perspectives of the Health Sciences Professions" to students entering their senior year in high school. In this course, students learned how dietitians, medical laboratory scientists, and physical and occupational therapists treat various disease states. Field trips and site visits provided additional exposure to the professions. A summer orientation and tutorial program was established to retain minority students enrolled in the coordinated undergraduate program. We recommend that this program be considered as a model for dietetics educators to use in developing other programs to increase the number of minorities in the profession.

The LeMoyne-Owen College--UTCHS cooperative educational program: a model for minority recruitment.

A program of cooperative education between LeMoyne-Owen College and the University of Tennessee Center for the Health Sciences (UTCHS) was designed to attract students from the undergraduate institution to the various health professional schools at UTCHS. The program was initiated by a black faculty member at UTCHS. It involved a faculty exchange between the two institutions and the implementation of several changes in the pre-health science curriculum at the undergraduate institution. Other components of the program included: the gift of equipment and supplies to LeMoyne-Owen College by UTCHS; counseling of LeMoyne-Owen students by UTCHS faculty members; the generation of private funds by the faculty and staff at UTCHS for the support of LeMoyne-Owen students participating in the cooperative education program; and broad exposure of LeMoyne-Owen students to the laboratories and clinical facilities at UTCHS.
