Organizing and implementing an Ilizarov program.

The Ilizarov external fixator has made a profound impact on orthopaedic science. With its circular design, it allows correction of three-dimensional deformities including rotation, angulation, translation, shortening, and widening, as well as lengthening and soft tissue defects. Because this device is largely patient centered and patient operated, it has presented a new challenge and career investment for the orthopaedic nurse. A comprehensive Ilizarov program is necessary to address the total patient and his multiple needs in any facility where the Ilizarov method of treatment is adopted. The Ilizarov program is a multidisciplinary team approach that provides a structure for administering and providing total patient care for the Ilizarov patient and his significant other(s).

A zero-base approach to medical school planning and budgeting.

The University of Michigan Medical School has concluded that the traditional budgeting process used by it and other academic institutions fails to discriminate adequately among programs, particularly in times of level or declining resources, and that this failure could result in mediocrity. As a result, the school decided to develop a new system for managing resources and chose to explore an approach that utilizes the principles of zero-base budgeting. An important reason for selecting this technique was its requirement that managers plan, evaluate, and set priorities for all programs, existing as well as new. After a feasibility study that produced encouraging results, a test implementation of the newly developed system was carried out in all six of the school's basic science departments and in two clinical departments. While some difficulties were encountered, including those normally associated with the introduction of a new and complex system, the results of the test implementation were encouraging, and the process is undergoing further development to broaden its application in the clinical departments.

Clinical applications of digital twin technology in In Vitro Fertilisation.

BACKGROUND: Digital twin technology, originating from aerospace and manufacturing industries, has emerged as a transformative tool in healthcare. In vitro fertilisation (IVF) faces persistent challenges including suboptimal embryo selection, unpredictable treatment outcomes, and limited personalisation of protocols. Despite advances in assisted reproductive technology, existing literature exhibits fragmentation: artificial intelligence applications in embryo selection, ovarian stimulation, and endometrial assessment have been developed independently without systematic integration into comprehensive treatment frameworks. Digital twin technology offers unprecedented opportunities to create virtual replicas of biological systems, enabling real-time monitoring, predictive modelling, and personalised treatment strategies. AIM: This narrative review aims to critically examine the current applications of digital twin technology in IVF, evaluate its potential benefits and limitations, synthesize existing evidence into an integrative conceptual model, and identify future directions for implementation in reproductive medicine. METHOD: A comprehensive narrative review was conducted using PubMed, Scopus, Web of Science, and IEEE Xplore databases. A narrative review approach was selected over systematic review to accommodate the heterogeneity of evidence types in this emerging field, including theoretical frameworks, simulation studies, and proof-of-concept implementations that would be excluded from systematic reviews. Search terms included "digital twin," "IVF," "in vitro fertilisation," "assisted reproductive technology," "embryo selection," and "predictive modelling." Studies published between 2015 and 2025 were included, focusing on original research articles, systematic reviews, and proof-of-concept studies describing digital twin applications in reproductive medicine. RESULTS: Digital twin technology in IVF demonstrates significant potential across multiple domains including embryo development simulation, ovarian response prediction, endometrial receptivity modelling, and personalised stimulation protocols. Current applications integrate artificial intelligence, machine learning algorithms, time-lapse imaging, and omics data to create comprehensive virtual models. Early evidence suggests improvements in embryo selection accuracy, ovarian response prediction, and treatment protocol optimization, though large-scale randomized controlled trials remain limited. Implementation challenges include data integration complexity, computational requirements, regulatory considerations, and validation requirements. CONCLUSION: Digital twin technology represents a paradigm shift in IVF practice, offering personalised, predictive, and precision medicine approaches. This review synthesizes existing evidence to propose an integrative conceptual model for digital twin implementation across the IVF treatment spectrum, identifies critical knowledge gaps, and establishes research priorities to advance clinical translation. Despite current limitations, continued advancement promises improved success rates and patient outcomes.

Systematic review of the mutations in the active antigenic site Ø of the prefusion F protein of the Respiratory Syncytial Virus (RSV) following the implementation of monoclonal antibody prophylaxis.

BACKGROUND: Monoclonal antibody (mAb) nirsevimab, which targets the antigenic site Ø of the prefusion F protein (pre-F) of RSV, was introduced for RSV prophylaxis in several countries. METHODS: A systematic search was conducted between January 1, 2022, and July 31, 2026 for studies analyzing substitutions within the epitope of pre-F RSV protein, which is the target of nirsevimab, after the implementation of the mAb. We searched across PubMed, Scopus, Web of Science and ClinicalTrial.gov for studies involving children with confirmed RSV infection, that conducted genomic analysis. RESULTS: Seven studies (five observational and two randomized controlled trials) including 2156 RSV-positive samples (RSV-A: 1347, RSV-B: 809) were analyzed. RSV-A strains showed limited variability within antigenic site Ø, with K65R being the most common substitution and K209E being the only intermediate-resistance RSV-A substitution. RSV-B strains demonstrated substantially higher substitution frequencies, particularly involving I206M, Q209R, and S211N. Most identified substitutions appeared to represent naturally occurring polymorphisms and retained susceptibility to nirsevimab, while multiple RSV-B substitutions and combinations involving residues 64-68 and 204-208 demonstrated reduced susceptibility or high-level resistance. Resistance-associated variants were detected in 28 of 2156 (1.3%) RSV-positive samples and exclusively among nirsevimab breakthrough infections. In a sub-analysis restricted to nirsevimab-treated individuals, resistance-associated variants were significantly more frequent among RSV-B than RSV-A (9.8% vs 0.5%; p < 0.001). CONCLUSION: Most substitutions that were detected within the nirsevimab antigenic site reflect ongoing natural RSV evolution and do not significantly affect nirsevimab susceptibility. However, detection of resistance-associated variants highlights the importance of continuous genomic and phenotypic surveillance.

Principles of clinical medicine: an interdisciplinary integrated 2-year longitudinal course.

In keeping with the Report of the Panel on the General Professional Education of the Physician (Association of American Medical Colleges 1984), Oregon Health Sciences University (OHSU) School of Medicine is in the midst of revising its curriculum. After a 4-year process, the Curriculum Committee mandated development of the Principles of Clinical Medicine course, a 2-year longitudinal course integrating input from both basic and clinical science departments. We describe the steps leading to the course's implementation, its administrative and organizational structure, the evaluation of student performance, teacher training, course curriculum, and the use of interdisciplinary teaching. This course embodies many of the changes called for in the AAMC Report and serves as a model for interdisciplinary education.

The book availability study as an objective measure of performance in a health sciences library.

In its search for an objective overall diagnostic evaluation, the University of Illinois Library of the Health Sciences' Program Evaluation Committee selected a book availability measure; it is easy to administer and repeat, results are reproducible, and comparable data exist for other academic and health sciences libraries. The study followed the standard methodology in the literature with minor modifications. Patrons searching for particular books were asked to record item(s) needed and the outcome of the search. Library staff members then determined the reasons for failures in obtaining desired items. The results of the study are five performance scores. The first four represent the percentage probability of a library's operating with ideal effectiveness; the last provides an overall performance score. The scores of the Library of the Health Sciences demonstrated no unusual availability problems. The study was easy to implement and provided meaningful, quantitative, and objective data.

Early outreach: career awareness for health professions.

"Early outreach" may be defined as a long-term, talent-development strategy designed to prepare a well qualified pool of disadvantaged and underrepresented minority applicants for entry into health professions schools, particularly medical schools. The concept of early outreach is to prepare, motivate, and educate talented, economically disadvantaged junior high or secondary school students to gain the necessary academic qualifications to make high school graduation, college attendance, and health careers a reality. In this paper the author defines the problem to which early outreach is addressed and discussed the contextual and historical background of the concept. A number of programs at the Health Sciences Center at the University of Illinois at Chicago designed and implemented to provide a model to achieve the concept of early outreach are described.

ConceptDrift: leveraging spatial, temporal and semantic evolution of biomedical concepts for hypothesis generation.

MOTIVATION: Hypothesis generation is a fundamental problem in biomedical text mining that aims to generate ideas that are new, interesting, and plausible by discovering unexplored links between biomedical concepts. Despite significant advances made by existing approaches, they do not fully leverage the evolutionary properties of biomedical concepts. This is limiting because scientific knowledge continually evolves over time, with new facts being added and old ones becoming obsolete. Thus, it is crucial to capture the evolutionary properties of biomedical concepts from multiple perspectives (e.g. spatial, temporal, and semantic) to generate hypotheses that reflect the up-to-date information landscape of the biomedical domain. RESULTS: We introduce a novel framework, ConceptDrift, that models the hypothesis generation task as a sequence of temporal graphlets and simultaneously encodes spatial, temporal, and semantic change. Unlike existing approaches that treat these dimensions independently, ConceptDrift is the first to provide a holistic understanding of concept evolution by integrating them into a unified framework. Grounded in the theories of the Distributional Hypothesis and Conceptual Change, our method adapts these principles to the unique challenges of large-scale biomedical literature. We conduct extensive experiments across multiple datasets and demonstrate that ConceptDrift consistently outperforms state-of-the-art baselines in generating accurate and meaningful hypotheses. Our framework shows immediate practical benefits for web-based literature mining tools in life sciences and biomedicine, offering more robust and predictive feature representations.

Social work training of new health professionals.

The Child Health Associate program provides a model for using social workers in the training of new health professionals. Administratively, social workers have contributed to curriculum development in the behavioral sciences. They have influenced decisions regarding student selection and have developed and implemented a faculty adviser program. Because of their practical experience as primary care practitioners, social workers have been able to define effectively the skills needed by the new professionals to meet the social and emotional needs of their patients. Social workers have made use of their contacts in hospitals and communities to design and implement courses and clinics that combine in a meaningful manner theoretical material and practical experiences in patient contact. Evaluative research in the area of interviewing skills and crisis management demonstrates that the teaching methods applied by the social work profession are effective in increasing the level of students' interviewing skills in clinical practice and help prepare them to recognize familiy crises.

Bionic organs.

When a lizard loses its tail, a new caudal appendage soon grows to replace the one that is missing. But when a human loses a kidney, severs a peripheral nerve or worse, the spinal cord, that organ is lost forever. Such at least is conventional thinking. But imagine that the victim of an industrial accident with a paralyzed hand could achieve new levels of function by inducing axonal regrowth through a synthetic nerve guidance channel; or that a Parkinsonian patient's symptoms could be relieved by implanting in his brain neural tissue encased in a selectively permeable polymer envelope; or that the inexorable progression of the vascular complications of juvenile diabetes could be stopped, even reversed, by a membrane-protected xenograft of insulin-producing tissue. This is the dream of bionic organ science. It is predicated on two lines of technological achievement: the availability of ultra-thin, biocompatible, selectively permeable polymer membranes which can protect a transplant against immune rejection while allowing solute exchange between the graft and its environment; and the synthesis of novel materials, some biostable, some bioresorbable, which can serve as scaffolding or anchor for tissue regrowth in the geometrically and chemically controlled environment of an implant. The fabrication, growth and survival of composites of living tissues with synthetic polymers, often enhanced by the incorporation of specific cell growth factors or inhibitors, has been demonstrated at the tissue culture level, and extended in vivo to experimental models of human endocrine deficiency or neurological defects. The key to progress with bioartificial organs is the confluence of knowledge ranging from materials science to cell and molecular biology to experimental surgery. Obstacles to clinical implementation of this new therapeutic concept include: large scale procurement of specific tissue structures or isolated postmitotic cells from animal sources; demonstration of safety and efficacy of spontaneously occurring, bioactive tumor cell lines; verification of long-term stability and bio-acceptance of polymer implants; and industrialization of the fabrication process to meet quality control, shelf-life and commercial distribution requirements.(ABSTRACT TRUNCATED AT 400 WORDS)

A model for a health career information center.

A model health career information center was developed and evaluated at a university health science center. One part of the information center is a statewide, toll-free health careers hotline which provides information about health careers to high school and college students, parents, counselors, and teachers, especially in small schools and rural areas, which are not usually included in recruiting circuits. Evaluation of the hotline after one year of operation has indicated that it fills a need, is considered useful by callers, and is of a relatively small cost, considering the geographical coverage. The model information system proposed can be implemented in phases with only slight modifications to meet the unique needs of specific health science centers or their geographical location.

Prevention and health policy: a view from the social sciences.

A theoretical framework is outlined which identifies four major problem areas which must be dealt with in the formulation, implementation, and evaluation of social policy. Certain issues relevant to policy concerning health promotion and disease prevention are discussed within this framework. The first problem area, adaptation, is concerned primarily with resources; the second area, goal attainment, deals with organizational issues; the third, integration, is concerned with motivations; the fourth, pattern maintenance, concentrates on questions of values. Policymaking is seen as an attempt by governing bodies to resolve problems in all these areas, and the success of any policy may be judged by the extent to which major issues in each area are dealt with equitably and reasonably.
