Neonatal skin care: evaluation of the AWHONN/NANN research-based practice project on knowledge and skin care practices. Association of Women's Health, Obstetric and Neonatal Nurses/National Association of Neonatal Nurses.

OBJECTIVE: To develop and evaluate an evidence-based clinical practice guideline for assessment and routine care of neonatal skin, educate nurses about the scientific basis for practices recommended in the guideline, and design procedures that facilitate implementation of the project guideline into clinical practice. DESIGN: Descriptive report of the collaborative neonatal skin care research-based practice project of the Association of Women's Health, Obstetric and Neonatal Nurses and the National Association of Neonatal Nurses. SETTING: Neonatal intensive-care unit (NICU) and special-care nurseries and well-baby nurseries in 51 hospitals located throughout the United States. PARTICIPANTS: Member site coordinators (N = 51), nurses who work at the selected sites, and the neonates observed during both the pre- and postimplementation phases of the project (N = 2,820). METHOD: An evidence-based clinical practice guideline was developed, sites were selected from all respondents of the call for sites, site coordinator training was provided, data collection was facilitated by project-specific data collection tools, and the project was evaluated by the science team. MAIN OUTCOME MEASURES: Diversity and numbers of sites represented, patient representation, site coordinator knowledge of neonatal skin care pre- and postimplementation, use of project-designed implementation tools, satisfaction with project guideline and the data collection process, changes in practices and product use, and site coordinators' experiences during guideline implementation. RESULTS: Fifty-one sites completed the project, representing NICU, special-care, and well-baby nurseries in both academic and community hospital settings in 27 states. Registered nurses working in these sites totaled 4,754 full-time equivalent positions (FTEs) (in NICU/special-care and well-baby nurseries). Site coordinators demonstrated increased knowledge of research-based neonatal skin care and satisfaction with the implementation tools and data collection process. Product use changed, reflecting acquisition of new knowledge. Barriers to implementation of the guideline were identified. CONCLUSIONS: The AWHONN/NANN Neonatal Skin Care Research-Based Practice Project demonstrated increased knowledge among site coordinators who received training, facilitated changes in neonatal skin care as defined by the practice guideline, and thus advanced evidence-based clinical practice.

The changing role and legitimate boundaries of epidemiology: community-based prevention programmes.

Epidemiology is the basic science of public health. It combines medical and social sciences, both of which are developing with new inventions. Therefore, the role of epidemiology and its boundaries are also changing over time. An important role of epidemiology is to develop and implement community-based control programmes for major diseases in the community. Such programmes are essential for large scale public health policy. It is necessary that epidemiological research can as freely as possible test new methods of disease prevention and health promotion. The first community-based control programme for cardiovascular diseases, the North Karelia Project is reviewed against this background. At present, it is still possible to define the boundaries of epidemiology geographically and culturally, but in the future, however, it will become more difficult. There is no doubt that epidemiology will remain as the basic science of public health but the scope of public health problems are growing much wider. These include the prevention of the final epidemic--the destruction of our planet by nuclear bombs. In the control of the existing epidemics and in the prevention of new ones the boundaries of epidemiology cannot stay rigid but they must be changing as new facts about the emerging public health problems are identified.

Challenges and lessons learned since implementation of the safety pharmacology guidance ICH S7A.

The International Conference on Harmonization, Topic S7A guidance (ICH S7A) on safety pharmacology for human pharmaceuticals has been in effect for 3 years in Europe, the United States and Japan. Surveys of the pharmaceutical industry, regulatory agencies and the audience attending the 4th Annual Meeting of the Safety Pharmacology Society have helped identify and address areas of controversy, as well as those challenges that have emerged since implementation of the guidance worldwide. Overall, ICH S7A has been successfully implemented. The guidance provides for "Good Laboratory Practice" compliant "safety pharmacology core battery" of studies that are generally performed prior to first administration to humans. The approach is science-driven and specifies the use of robust and sophisticated in vitro and/or in vivo assays. There are, however, some areas that require further refinement/clarification such as the specifics of study design including the selection of dose/concentration, choice of species, modeling of the temporal pharmacodynamic changes in relation to pharmacokinetic profile of parent drug and major metabolites, use of an appropriate sample size, statistical power analysis as a means of demonstrating the sensitivity of the model system, testing of human-specific metabolites and demonstrating not only the model's sensitivity, but also its specificity for predicting adverse events in humans. There was also discussion of when these studies are needed in relation to the clinical development plan. Representatives from the pharmaceutical industry and regulatory agencies see the implementation of ICH S7A as a major step forward towards identifying the risk to Phase 1 and 2 volunteers and patients. It remains to be seen, however, whether and in what ways the ICH S7A-based strategy will contribute to the modification of the integrated risk assessment during the latter stages of clinical development or once drugs have been introduced to the marketplace.

Ground based ISS payload microgravity disturbance assessments.

In order to verify that the International Space Station (ISS) payload facility racks do not disturb the microgravity environment of neighboring facility racks and that the facility science operations are not compromised, a testing and analytical verification process must be followed. Currently no facility racks have taken this process from start to finish. The authors are participants in implementing this process for the NASA Glenn Research Center (GRC) Fluids and Combustion Facility (FCF). To address the testing part of the verification process, the Microgravity Emissions Laboratory (MEL) was developed at GRC. The MEL is a 6 degree of freedom inertial measurement system capable of characterizing inertial response forces (emissions) of components, sub-rack payloads, or rack-level payloads down to 10(-7) g's. The inertial force output data, generated from the steady state or transient operations of the test articles, are utilized in analytical simulations to predict the on-orbit vibratory environment at specific science or rack interface locations. Once the facility payload rack and disturbers are properly modeled an assessment can be made as to whether required microgravity levels are achieved. The modeling is utilized to develop microgravity predictions which lead to the development of microgravity sensitive ISS experiment operations once on-orbit. The on-orbit measurements will be verified by use of the NASA GRC Space Acceleration Measurement System (SAMS). The major topics to be addressed in this paper are: (1) Microgravity Requirements, (2) Microgravity Disturbers, (3) MEL Testing, (4) Disturbance Control, (5) Microgravity Control Process, and (6) On-Orbit Predictions and Verification.

Diagnostic, therapeutic, didactic, data bank utilization of computerized monitoring in a critical care center.

At the beginning of their discovery informatic technique procedures and methodologies generated a great wave of hopes for progress in theoretical and practical fields of human activity, but when passing to concrete application, an ebb phase followed. Recent theoretical and technical progress, however, has generated an enormous new up-surge of interest for applications of informatic processing in all fields of science. Medicine in the last three decades has gone through the same phases observed in other disciplines. In the ICU the potentiality of exploitation of the informatic techniques appeared enormous, however, initially from a practical point of view it found only limited, sectorial experimentation and implementation, but afterwards a limited and slow process of parcellar infiltration, the high tide of informatic, has broken the dam and deeply advanced in its territory, obliging the staff to a great effort of cultural and technical updating to cope with it. After recalling some of the history of Computer Science or Informatic, even if history was only yesterday, we will present some examples of the hand made experience of an ICU, (namely ours) with limited economical resources, and whose interest in this field arises from actual needs, personal interest and enthusiasm of a staff who works, on its free time, after fulfilling its stressing routine.

Fractional designs: a simulation study of usefulness in the social sciences.

Fractional designs can be extremely useful in social science research, especially when a large number of factors is involved. Reluctance for the use of fractional designs seems to be warranted for two reasons: (1) In the social sciences, the amount of measurement error is often large, which may decrease the power, and (2) higher order interactions are assumed to be nonsignificant, which is difficult to guarantee without sufficient research. This simulation study shows the effects of measurement error and assumption violations under various conditions. It is concluded that fractional designs handle measurement error gracefully and that they are as powerful as a full design when equal degrees of freedom are available. Significant interaction effects can cause serious problems, especially in situations with low or intermediate measurement error, and can lead to erroneous conclusions. Only when estimated confounded effects are clearly not significant, the chance of a wrong decision is reasonably small. Therefore, fractional designs are especially warranted for the exclusion of irrelevant factors. However, we note pitfalls in the use of Version 1.0 of the program Trail Run from SPSS, Inc., to implement the procedures.

Abduction--a way to deeper understanding of the world of caring.

In this article, abduction is discussed as a possible way of developing an epistemology for an autonomous caring science based on an ontology that requires deeper understanding of the world of caring. The intention is to elicit a more distinct caring-scientific pattern of knowledge based on the innermost core and historical conditions of caring. Abduction makes it possible to perceive connections on a deeper level and to penetrate in a way that reveals a richness of meaning, reflecting the true being in the dynamic process which is expressed in clinical reality. In the tradition of knowledge developed by Peirce, a synthesis of Hume's and Kant's tradition of knowledge, abduction is a fundamental idea. Peirce sees abduction as an operation of thought in which the recognition of underlying patterns makes a complex reality comprehensible. We regard the triad of abduction, induction and deduction as the basis for developing a caring-scientific epistemology where abduction makes a synthesizing abstraction possible and may implement understanding of deeper patterns.

The implementation of health promotion: a new structural perspective.

Although health promotion has become a critical concept in public health, both research and practical projects in this area are almost devoid of theory. The present article uses a theory of complexity and structure to organize the different elements of health promotion in a new perspective. This perspective involves (1) new ways for looking at patterns of behavioral risk factors and health-related lifestyles. It (2) relates health promotion to policy making. In particular, it (3) focuses on a comprehensive model of the implementation process, revealing the true interrelationship of relevant elements to the concept of health promotion. In this context, it (4) becomes obvious that the reflexivity and recursiveness of scientific analyses are an integral part of the structure of health promotion. Thus, the professional role of the social scientist with regards to the implementation and utilization of scientific knowledge in the field of public health policy will be discussed. Finally, the role of appropriate theory is emphasized as a strategy for improving the practice of health promotion and to further the development of a new public health.

The human skin: fragrances and pheromones.

Non-human mammalian pheromones are commonly used as perfumery ingredients. The actual purpose for using these compounds is as a fixative or carrier for the odor effects of the other ingredients as well as a contributor, in part, to the over-all scent of the perfume. Although such materials are used for their fixative and odor qualities rather than their pheromonal effects, perfumes are generally marketed as having the ability to enhance sexual attractiveness. While providing a scent may elicit a positive pleasant response, this should not be confused with a pheromone response. The attractive effect of perfumes is principally related to the effect of the pleasant scent. A more logical approach would be to use human pheromones which, for humans, are both more natural and more effective as true sensual attractants. It seems likely that implementation of this approach will constitute an important paradigm in the perfume industry as perfumery moves from the realm of art to that of science.

Applications of quantum AI in brain disorder diagnosis: A systematic review.

BACKGROUND AND OBJECTIVE: Brain disorder diagnosis and prediction remain challenging because neuroimaging, electrophysiological, behavioral, and multimodal data are high-dimensional, noisy, heterogeneous, and limited by small clinical cohorts. This systematic review synthesised applications of quantum artificial intelligence (QAI) for brain disorder diagnosis, prediction, detection, and monitoring. METHODS: Following PRISMA guidelines, studies published from 2016 to 13 January 2026 were retrieved from Scopus, Web of Science, and IEEE Xplore. After screening, 36 studies met the eligibility criteria and were qualitatively analysed according to disorder category, data modality, QAI method, implementation setting, validation strategy, and performance. RESULTS: At the broader disease-group level, neurodegenerative disorders were the most frequently investigated, followed by mental health and psychiatric disorders. At the individual level, Parkinson's disease and schizophrenia were the leading applications, followed by depression, anxiety, Alzheimer's disease, and stress-related tasks. MRI-based modalities were the most frequently used data source, followed by multimodal data and EEG. Methodologically, primary QAI approaches were dominated by quantum neural and QDL architectures, followed by quantum-inspired optimization or feature-selection methods and quantum-kernel/conventional QML classifiers. Qiskit/IBM Quantum and PennyLane were the most frequently reported quantum software frameworks. However, most studies relied on simulators, classical quantum-inspired implementations, or unclear implementation settings, with limited real-hardware evaluation. CONCLUSIONS: QAI shows emerging potential for brain disorder analysis, particularly through hybrid quantum-classical learning, quantum neural architectures, quantum-kernel methods, and quantum-inspired optimization. Nevertheless, current evidence remains preliminary and requires larger datasets, subject-level and external validation, fair classical benchmarking, noise-resilient circuits, real quantum hardware evaluation, explainability, and clinical validation.

The costs of safeguarding privacy: one research organization's experience.

While academic health research has always observed strict vigilance in the guardianship of the rich information found in health databases, new legislation faced by all organizations ups the ante even higher. Research organizations like the Institute for Clinical Evaluative Sciences are delving into even more rigorous policies to keep sensitive information secure while preserving the value that dedicated research provides. The costs of implementing privacy protections are of great concern to Canadian researchers. This report discusses basic costs associated with privacy practices undertaken at the Institute.

Efficient Training of Recurrent Neural Network with Time Delays.

Training recurrent neural networks to perform certain tasks is known to be difficult. The possibility of adding synaptic delays to the network properties makes the training task more difficult. However, the disadvantage of tough training procedure is diminished by the improved network performance. During our research of training neural networks with time delays we encountered a robust method for accomplishing the training task. The method is based on adaptive simulated annealing algorithm (ASA) which was found to be superior to other training algorithms. It requires no tuning and is fast enough to enable training to be held on low end platforms such as personal computers. The implementation of the algorithm is presented over a set of typical benchmark tests of training recurrent neural networks with time delays. Copyright 1996 Elsevier Science Ltd.

Security in perspective; luxury or must?

In this paper, security in health information systems is put into perspective. The further penetration of information technology into health care is discussed and it is concluded that information systems have already become a vital component, not only for the logistics of the health care institution but also for the rendering of care and cure. Health care depends heavily on adequate data, so availability and integrity are equally important. In view of the sensitive nature of many patient data, the importance of confidentiality was recognised long before computers were invented. For widespread use of IT in health care it is of vital importance that computers can be trusted in respect of confidentiality. This paper emphasises the need to pay attention to security and suggests a responsible approach with implementation of both technical and organisational measures.

Standards for systems biology.

High-throughput technologies are generating large amounts of complex data that have to be stored in databases, communicated to various data analysis tools and interpreted by scientists. Data representation and communication standards are needed to implement these steps efficiently. Here we give a classification of various standards related to systems biology and discuss various aspects of standardization in life sciences in general. Why are some standards more successful than others, what are the prerequisites for a standard to succeed and what are the possible pitfalls?

[Developing an evidence based clinical guideline on cardiac rehabilitation--Phase 2: comparative analysis of the present level of service provision in cardiac rehabilitation based on the KTL statistics].

BACKGROUND: This project aims to develop an evidence based clinical guideline for the rehabilitation of cardiac patients considering recent scientific literature (stage 1), procedures received by cardiac patients undergoing rehabilitation carried by the German Federal Insurance Institute for Salaried Employees (BfA) based on the Classification of Therapeutic Procedures (KTL) (stage 2), and expert agreement of the professionals involved (stage 3). This study presents the results of stage 2. The analysis of the KTL-statistics was carried out to determine whether it is essentially necessary to implement a guideline and to define "critical" aspects, i. e. aspects that require high priority implementation. The project is part of a research programme funded by the BfA. METHODS: 317 out of the 840 possible KTL-codes were attributed to one of twelve therapeutic modules that--according to the results of stage 1--are characteristics of cardiac rehabilitation. For these modules the number of people having received therapeutic procedures belonging to the respective module the duration per patient and per week were calculated. The influence of concomitant factors such as age, gender and indication were analysed multivariately. Furthermore, the hospitals involved were compared. The analyses are based on approximately 87,400 KTL-entries from 5,494 patients (indication: "myocardial infarction" or "coronary artery bypass surgery") treated in 2000. RESULTS: On average the patients receive therapeutic procedures "stemming" from 5.5 modules. More than 90 % receive procedures assigned to the modules "endurance training" or "motivation", respectively, and almost 70 % from "nutrition training". The other modules are rendered not consistently and occasionally to a relatively small degree. Younger patients following a myocardial infarction receive therapeutic procedures more frequently and longer while older patients after bypass surgery are treated less frequently and for a shorter duration. There is substantial variability between individual clinics. DISCUSSION: It appears to be necessary to implement clinical practice guidelines in all evaluated therapeutic modules but "endurance training" and "motivation". An evidence based clinical practice guideline for the rehabilitation of cardiac patients should detail the kind and extent of procedure(s) required. It should also inform about the lack of evidence for variations in treatment with respect to age, gender, or indication. To facilitate monitoring of the degree of implementation of the guideline precise instructions for the documentation using the KTL should be developed and implemented. As a next step towards an evidence based, empirically proven and acceptable guideline this project's results will be discussed with experts from science and clinical practice.

Using the Web to aid biochemists and microbiologists: an example of computer-based learning using PCR as an example.

The aim of this study was two-fold: to make available to the medical community a fast, efficient tool for troubleshooting PCR problems, and to demonstrate that hypermedia allow one to approach this kind of problem in a new, more useful way. The Web provides access to an enormous amount of information in the medical area, and in particular enables troubleshooting of new techniques in the medical laboratory. Currently it is possible to find textual information but it is not always easy to find hypermedia information. In many cases authors change only the means of dissemination of a book or paper to the Web, but do not adapt the information to the features of this new medium. The prototype of our hypermedia application was developed using Director and Flash programs (Macromedia), the application was developed from a decision tree built as a result of information compiled from expert PCR users and the existing literature. It was implemented on a website using Dreamweaver (Macromedia). The usefulness and possibilities of this application have been tested with physicians, medical laboratory technicians, and health science students, and have been proven to be more effective than traditional methods, both in education processes and in helping researchers and medical laboratory technicians in their daily work. The advance and popularization of the Internet in the medical profession requires information on the Web to adapt to the advantages offered by hypermedia. This new step must be taken, and the Web must offer medical users not only a different medium of information distribution but also a new way of handling and obtaining information.

Treatment of pediatric overweight: an examination of feasibility and effectiveness in an applied clinical setting.

OBJECTIVE: To examine the effectiveness and feasibility of an evidence-based treatment for weight loss in children. METHODS: A total of 41 children who were overweight and their families were provided a modified version of the Traffic Light Diet (TLD) in an applied setting. Children who received treatment as usual (TAU) constituted a comparison sample. RESULTS: Children receiving the modified TLD demonstrated a significantly greater reduction in standardized body mass index (z-BMI) than children receiving TAU. CONCLUSIONS: The TLD is a feasible treatment that can be implemented in applied settings that include samples often excluded from treatment efficacy studies. Results are discussed in the context of bridging the gap between science and service.
