Harnessing the power of an intelligent health environment in cancer control.

In 1971, when Congress declared "war on cancer," the public's perception was driven by an image of a single cure for a single disease. What researchers have learned since that time is that cancer is a formidable enemy made up of more than 100 different disease etiologies. The war on cancer became a war of the 21st century; a war to be fought on multiple fronts against a diffuse enemy and for which prevention was the most judicious path to victory. To fight this new war on cancer, the National Cancer Institute must seek to harness the power of health informatics to create a supportive environment for transforming science, delivering safe and patient-centric health care, and creating an environment of personal empowerment in public health. Three different types of health informatics applications are implicated: (a) applications in bioinformatics, which are intended to revitalize the engine of scientific discovery; (b) applications in medical informatics, which will create a safer and more effective environment for delivery; and (c) applications in consumer informatics, which will enable individuals to advance the charge of their own ongoing health care over the course of their lives. To keep these applications on track, health care administrators must take a sociotechnical approach to implementation. The new systems must be built into the health care environment in such a way that they support human capacities, provide failsafe backups in the face of cognitive and physical limitations, and support continuous quality improvement.

Information for pregnant women about caesarean birth.

BACKGROUND: Information is routinely given to pregnant women, but information about caesarean birth may be inadequate. OBJECTIVES: To examine the effectiveness of information about caesarean birth. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth register, CENTRAL (26 November 2002), MEDLINE [online via PubMed 1966-] and the Web of Science citation database [1995-] (20 September 2002), and reference lists of relevant articles. SELECTION CRITERIA: Randomised controlled trials, non-randomised clinical trials and controlled before-and-after studies of information given to pregnant women about caesarean birth. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Missing and further data were sought from trial authors unsuccessfully. Analyses were based on 'intention to treat'. Relative risk and confidence intervals were calculated and reported. Consumer reviewers commented on adequacy of information reported in each study. MAIN RESULTS: Two randomised controlled trials involving 1451 women met the inclusion criteria. Both studies aimed to reduce caesarean births by encouraging women to attempt vaginal delivery. One used a program of prenatal education and support, and the other cognitive therapy to reduce fear. Results were not combined because of differences in the study populations. Non-clinical outcomes were ascertained in both studies through questionnaires, but were subject to rates of loss to follow-up exceeding 10%.A number of important outcomes cannot be reported: knowledge or understanding; decisional conflict; and women's perceptions: of their ability to discuss care with clinicians or family/friends, of whether information needs were met, and of satisfaction with decision-making. Neither study assessed women's perception of participation in decision-making about caesarean birth, but Fraser 1997, who examined the effect of study participation on decision making, found that women in the intervention group were more likely to consider that attempting vaginal birth was easier (51% compared to 28% in control group), or more difficult (10% compared to 6%). These results could be affected by the attrition rate of 11%, and are possibly subject to bias. Neither intervention used in these trials made any difference to clinical outcomes. About 70% or more women attempted vaginal delivery in both trials, yet caesarean delivery rates exceeded 40%, at least 10% higher than was hoped. There was no significant difference between control and intervention groups for any of the outcomes measured: vaginal birth, elective/scheduled caesarean, and attempted vaginal delivery. Outcome data, although similar for both groups, were not sufficient to compare maternal and neonatal morbidity or neonatal mortality. There was no difference in the psychological outcomes for the intervention and control groups reported by either of the included trials. Consumer reviewers said information for women considering a vaginal birth after caesarean (VBAC) should include: risks of VBAC and elective caesarean; warning signs in labour; philosophy and policies of hospital and staff; strategies to improve chances of success; and information about probability of success with specific care givers. REVIEWER'S CONCLUSIONS: Research has focussed on encouraging women to attempt vaginal delivery. Trials of interventions to encourage women to attempt vaginal birth showed no effect, but shortcomings in study design mean that the evidence is inconclusive. Further research on this topic is urgently needed.

The Functional Magnetic Resonance Imaging Data Center (fMRIDC): the challenges and rewards of large-scale databasing of neuroimaging studies.

The Functional Magnetic Resonance Imaging Data Center (fMRIDC) (http://www.fmridc.org) was established in the Autumn of 1999 with the objective of creating a mechanism by which members of the neuroscientific community may more easily share functional neuroimaging data. Examples in other sciences offer proof of the usefulness and benefit that sharing data provides through encouraging growth and development in those fields. By building a publicly accessible repository of raw data from peer-reviewed studies, the Data Center hopes to create a similarly successful environment for the neurosciences. In this article, we discuss the continuum of data-sharing efforts and provide an overview of the scientific and practical difficulties inherent in managing various fMRI data-sharing approaches. Next, we detail the organization, design and foundation of the fMRIDC, ranging from its current capabilities to the issues involved in the submitting and requesting of data. We discuss how a publicly accessible database enables other fields to develop relevant tools that can aid in the growth of understanding of cognitive processes. Information retrieval and meta-analytic techniques can be used to search, sort and categorize study information with a view towards subjecting study data to secondary 'meta-' and 'mega-analyses'. In addition, we detail the technical and policy challenges that have had to be addressed in the formation of the Data Center. Among others, these include: human subject confidentiality issues; ensuring investigator's rights; heterogeneous data description and organization; development of search tools; and data transfer issues. We conclude with comments concerning the future of the fMRIDC effort, its role in promoting the sharing of neuroscientific data, and how this may alter the manner in which studies are published.

What do we know about medical invalidation and related concepts? - A scoping review and thematic analysis about the definitions, measurements, causes, consequences and potential solutions for medical invalidation.

BACKGROUND: Medical invalidation, medical gaslighting, and related constructs have gained visibility in public discourse but remain inconsistently defined in scientific literature. Despite growing research-often focused on specific diseases- to date, no single review has comprehensively synthesized their definitions, causes, consequences, or methods of measurement. This scoping review addresses this gap by examining medical invalidation and related constructs. METHODS: Using a preregistered protocol, we systematically searched PubMed, CINAHL, Web of Science, Google Scholar, and ProQuest (dissertations) without year restrictions. Eligible sources included peer-reviewed empirical, theoretical, and conceptual work in English addressing invalidation, gaslighting, or closely related notions within healthcare. A total of 158 studies were identified through database searches and citation tracking. Data extraction followed a standardized schema, and findings were synthesized descriptively and through thematic analysis to clarify terminology, map determinants and outcomes, and identify existing measurement approaches. RESULTS: The results showed substantial inconsistency in how "invalidation," "not being taken seriously," and "gaslighting" were defined. Medical invalidation emerged as a multifactorial phenomenon driven by diagnostic challenges, structural and societal factors, provider and patient characteristics, stigma, misattribution, interactional dynamics, academic knowledge gaps, and disease-related complexity. Invalidation was associated with wide-ranging behavioural, emotional, cognitive, physical, relational, and systemic harms, while validation had consistently beneficial effects. Proposed solutions in the summarized studies included communication improvements, clinician training, patient support, targeted research, and structural and systemic changes. DISCUSSIONS: Medical invalidation represents a complex, systemic issue with significant implications for patient safety. The discussion highlights its multifactorial origins, its potential to cause both psychological and physical harm, and the need for clearer conceptualisation within the field. Advancing research requires validated instruments and longitudinal designs to examine underlying mechanisms and consequences. Addressing medical invalidation will demand multi-level interventions to improve communication, reduce structural barriers, and promote equitable, patient-centred care.

The limits of empirical studies on research ethics.

The results of empirical research in psychology and psychiatry are increasingly being used to formulate as well as understand problems at the interface of law and psychiatry. There has been a proliferation of studies, such as the determinants of individual competence or threat to self or others, the results of which are influencing policy and legislative decisions as well as buttressing holdings in court cases. In this article, I explore the issues of interpretation of epidemiological studies, particularly the role of ideological positions on the design and results of empirical findings, the importance of the way data are interpreted, and the role of ideologies in the way research findings are presented to provide support for policy positions. Two levels of analysis are involved in determining the validity of a study. The first addresses the questions of whether the study meets the statistical and epidemiological requirements for reliable results. These include considerations such as the appropriateness of the study design and methods for gathering and interpreting data. The second focuses on the underlying framework of the study. This involves factors such as the perspectives and values of those conducting the study, the explicit and implicit dominating ideologies where they operate, and the extent to which the study is constructed to reaffirm specific ideologies. This level of analysis is essential for disclosing the influences of ideologies on the results of studies and the way in which data are interpreted. In this article, I try to demonstrate through critiques of selected studies that the first stage of analysis is insufficient without an examination of underlying preconceived values to establish the meaningfulness of results.

[Mental training--does it also help the modern surgeon?].

The demands on the modern surgeon are extremely complex. Especially in endoscopic surgery he must be able to carry out most complicated finemotoric motions which are not part of the natural action repertoire, sometimes under extreme conditions of stress. Such demands can be compared to those of top athletes. Within a cooperative project between the second chair of surgery of the University of Cologne and the sport psychologic working unit of the Heidelberg University department of sport and sports science the empirically sound Mental Practice (MP) which has been successfully applied in worldclass sports for a long time was modified so that an application of this training method is now possible for the training and continuing education of young surgeons. The following four types of surgery were emphasized: laparoscopic cholecystectomy, laparoscopic appendectomy, thyroidectomy and inguinal hernia. The article will focus on the detailed description of MP in surgery. At first, however, we are going to delineate MP in sports and will then turn to how it is modified and applied in the field of surgery. Besides the arrangement and exact description of surgeries, MP in this field requires the formulation of instructions which are summarized in instructional handbooks. These handbooks serve as target values for instrumental and cognitive simulation techniques which are applied in MP. The surgeon is thus provided with a foundation for the construction of functional mental representations of the surgery types which enables him to optimize the quality of his actions during the above mentioned surgeries.

Alzheimer's disease therapy - an update.

The 5th International Geneva/Springfield Symposium on Advances in Alzheimer Therapy focused on new therapeutic approaches for the treatment of Alzheimer 's disease (AD) based on the latest basic science data. The two major pharmacological principles of cholinergic therapy are 1) reduction of acetylcholine hydrolysis by means of acetylcholinesterase (AChE) inhibitors; and 2) direct stimulation of nicotinic or muscarinic receptors with selective agonists. Currently used AChE inhibitors are tacrine, donepezil hydrochloride, rivastigmine and metrifonate. In the area of muscarinic and nicotinic receptor modulation, studies were presented on AF-102B and AF-150(S), BIBN-99, CI-1017, RJR-2403, ABT-418, ABT-089, GTS-21 and SIB-1553A. Based on evidence of inflammatory mechanisms in the pathogenesis of AD, selective COX-2 inhibitors for the prevention and treatment of AD are a target of several pharmaceutical companies. Concerning known antiinflammatory drugs, results from controlled trials are expected soon. Estrogen replacement has been reported to produce cognitive and affective improvement in women with AD, and results from a number of studies were presented. Age-associated increases in oxidative stress may play a role in AD and thus antioxidants may also have a place in the therapy of this disease. The antioxidants vitamin E and selegiline are being investigated. Other drugs under investigation are propentofylline, Cerebrolysin, citicoline sodium, CDP-choline, memantine, Egb-761, calagualine and AIT-082. Iododoxorubicin may represent a new class of compounds able to interfere with the beta-amyloid cascade in AD and other brain amyloid diseases. Future preventive strategies in AD include genotype analysis and screening, presymptomatic diagnosis and avoidance of environmental risk factors.

Psychiatric disability and clinical decision making: the impact of judgment error and bias.

The psychiatric disability adjudicator is presented, with multiple types of evidence regarding claimants, and, utilizing primarily clinical judgment, must weigh and integrate this information before rendering a disability decision. The need to process large amounts of evidence in this fashion can result in the use of cognitive simplification strategies in the form of heuristics or specific types of decisional bias which can produce judgment error. The purpose of this review is to increase awareness regarding the role that bias can play in determining an individual's psychiatric disability status, using a large federal disability program for context purposes. Recommendations are also made regarding steps that can be taken to anticipate and reduce decision-making bias.

Reducing diagnostic errors in medicine: what's the goal?

This review considers the feasibility of reducing or eliminating the three major categories of diagnostic errors in medicine: "No-fault errors" occur when the disease is silent, presents atypically, or mimics something more common. These errors will inevitably decline as medical science advances, new syndromes are identified, and diseases can be detected more accurately or at earlier stages. These errors can never be eradicated, unfortunately, because new diseases emerge, tests are never perfect, patients are sometimes noncompliant, and physicians will inevitably, at times, choose the most likely diagnosis over the correct one, illustrating the concept of necessary fallibility and the probabilistic nature of choosing a diagnosis. "System errors" play a role when diagnosis is delayed or missed because of latent imperfections in the health care system. These errors can be reduced by system improvements, but can never be eliminated because these improvements lag behind and degrade over time, and each new fix creates the opportunity for novel errors. Tradeoffs also guarantee system errors will persist, when resources are just shifted. "Cognitive errors" reflect misdiagnosis from faulty data collection or interpretation, flawed reasoning, or incomplete knowledge. The limitations of human processing and the inherent biases in using heuristics guarantee that these errors will persist. Opportunities exist, however, for improving the cognitive aspect of diagnosis by adopting system-level changes (e.g., second opinions, decision-support systems, enhanced access to specialists) and by training designed to improve cognition or cognitive awareness. Diagnostic error can be substantially reduced, but never eradicated.

Clinical and cost-effectiveness of donepezil, rivastigmine and galantamine for Alzheimer's disease: a rapid and systematic review.

BACKGROUND: Alzheimer's disease is the most common cause of dementia and is characterised by an insidious onset and slow deterioration. The estimated prevalence of Alzheimer's disease for a standard health authority (500,000 people) is about 3330. Current service involves a wide range of agencies, and drug therapy for some patients. OBJECTIVES: To provide a rapid and systematic review of the clinical effectiveness and cost-effectiveness of donepezil, rivastigmine and galantamine in the symptomatic treatment of people suffering from Alzheimer's disease. METHODS: A systematic review of the literature was undertaken. METHODS - DATA SOURCES: Searches were made of electronic databases, including MEDLINE, EMBASE, The Cochrane Library, Database of Abstracts of Reviews of Effectiveness, NHS Economic Evaluation Database, National Research Register, Science Citation Index, BIOSIS, EconLit, MRC Trials database, Early Warning System, Current Controlled Trials, TOXLINE, Index of Scientific and Technical Proceedings, and Getting Easier Access to Reviews. All sources were searched over the period covered by the databases up to March/July 2000. Bibliographies of related papers were assessed for relevant studies and experts were contacted for advice and peer review, and to identify additional published and unpublished references. Manufacturer submissions to the National Institute for Clinical Excellence (NICE) were reviewed. METHODS - STUDY SELECTION: Studies were included if they fulfilled the following criteria: (1) INTERVENTION: donepezil, rivastigmine or galantamine used to treat Alzheimer's disease. (2) PARTICIPANTS: people diagnosed with Alzheimer's disease who meet the criteria for treatment with donepezil, rivastigmine and galantamine. (3) OUTCOMES: measures assessing changes in cognition, function, behaviour and mood, quality of life (including studies assessing carer well-being and carer-input), and time to institutionalisation. (4) DESIGN: systematic reviews of randomised controlled trials (RCTs) and RCTs comparing donepezil, rivastigmine or galantamine with placebo or each other or non-drug comparators were included in the review of effectiveness. Economic studies of donepezil, rivastigmine or galantamine used to treat Alzheimer's disease that included a comparator (or placebo) and both the costs and consequence (outcomes) of treatment were included in the review of cost-effectiveness. Studies in non-English language, and abstracts and conference poster presentations of systematic reviews, RCTs and economic evaluations were excluded. Two reviewers identified studies by independently screening study titles and abstracts, and then by examining the full text of selected studies to decide inclusion. METHODS - DATA EXTRACTION AND QUALITY ASSESSMENT: Data extraction and quality assessment were undertaken by one reviewer and checked by a second reviewer, with any disagreements resolved through discussion. The quality of RCTs was assessed using the Jadad scale and the quality of systematic reviews was assessed using criteria developed by the NHS Centre for Reviews and Dissemination. The quality of economic evaluation studies was assessed by their internal validity (i.e. the methods used) using a standard checklist, and external validity (i.e. the generalisability of the economic study to the population of interest) using a series of relevant questions. METHODS - DATA SYNTHESIS: The clinical effectiveness and cost-effectiveness of donepezil, rivastigmine and galantamine were synthesised through a narrative review with full tabulation of results of all included studies. In the economic evaluation, the reviewers assessed whether adjustments could be made to existing models to reflect the current situation in England and Wales. RESULTS - CLINICAL EFFECTIVENESS: (1) Donepezil--three systematic reviews and five RCTs (plus four studies from industry (unpublished data, submitted as commercial in confidence)) were found. Results suggest that donepezil is beneficial when assessed using global and cognitive outcome measures. (2) Rivastigmine--three systematic reviews and five RCTs (plus two studies from industry (unpublished data, submitted as commercial in confidence)) were found. Results suggest that rivastigmine is beneficial in terms of global outcome measures. (3) Galantamine--one systematic review and three RCTs (plus three studies from industry (unpublished data, submitted as commercial in confidence)) were found. Results suggest that galantamine is beneficial in terms of global, cognitive and functional scales. RESULTS - SUMMARY OF BENEFITS: It is difficult to quantify benefits from the evidence available in the literature. Statistically significant improvements in tests such as ADAS-cog (Alzheimer's Disease Assessment Scale cognitive subscale) may not be reflected in changes in daily life. (ABSTRACT TRUNCATED)

[Semantics of learned quackery in the 17th and 18th centuries].

In the 17th and 18th century republic of letters the problem of scientific fraud was met with a discourse of charlatanism. Departing from Johann Burchhard Menckes famous treatise on the Charlatanry of the learned the following essay traces how the accusations of academic and scientific misconduct put in terms of 'charlatanry' primarily helped to produce the new species of the erudite 'charlatan'. Facing a growing complexity of scientific culture this new frame of meaning, structured by numerous examples of scientific misconduct offered a new way of orientation in the world of learning. But besides its cognitive impacts the discourse of charlatanry allowed to create symbolic boundaries, which determined decisions upon the affiliation or non affiliation to the new forming scientific community by separating honourable from dishonourable scientific personae. Speaking of charlatanry therefore always implied a social distinction as much as a scientific. The discourses on charlatanry also mirror differentiations within the scientific field. At first dominated by a critique built on courteous or bourgeois values, the scientific field later on developed its own criteria of appraisal like authorship, originality, transparency etc. Attracting the attention of a further growing public sphere, the explicit verbalisation of claims not relating to the value system of a republic of letters primarily concerned with the production and distribution of knowledge finally led up to a more implicit moral economy of science. A change that at a large scale level can be described both as an internalisation of the values of scientific conduct and differentiation between justiciable and unjusticiable transgressions of the norms set up by the scientific community.

Quality of life philosophy IV. The brain and consciousness.

In this article we look at the brain's structure and function from a philosophical perspective. Although the brain at micro-level, with its trillions of ultra-thin nerve fibers, is one of the most complicated structures in the known universe, you can still grasp its composition if you go up to the level of the cell. How this structure functions is not quite clear. You can understand its function at fiber level, because it is fairly simple, and you can understand it at cell level, but it is already vague. Roughly speaking, you can envision a single nerve cell as a tiny, independent computer whose behavior is dependent on continuous calculations of all input. At organ level, the function can be understood as an extremely complex pattern machine. Finally, the brain"s function can be understood at the cognitive level as what provides consciousness through its ability to keep order in our complicated reality. The superior function of the brain is to connect the real us, our higher self, to the surrounding world. The brain has been developed so that it can create all possible complex patterns. The connectivity seems to imply that the patterns of the human brain are 1000-dimensional. It is our vision that these complicated patterns arise from basic patterns in the quantum matter of which everything is created. In our opinion, our consciousness" special utilization of a patterned aspect of nature is what lies behind inscrutable statements like "Man is created in God"s image". We suggest that these patterns in matter are the basic, creative force that influences all living organisms. Unfortunately, science has only just begun to understand these patterns. The Bible's description of the origin of man is two people eating from the Tree of Knowledge and as punishment they are expelled from the Garden of Eden. What does that mean? It means that, as conscious creatures, we no longer were an unproblematic, harmonious part of the world around us. The great question is why this consciousness about the world, provided by the brain, is not a gift that makes life better instead of getting us expelled from the Garden of Eden. We think that our real problem is the fact that we are still not in control of our consciousness. Instead of it serving us, we have become its slaves. If we come to understand brain and consciousness in order to solve this basic problem of our existence, we shall again be able to become a coherent part of the world, both as individuals and as a species. We share the vision that such an understanding of the problems of consciousness will make medical science holistic and will bring quality of life, health, and the ability to function to its patients.

Anorexia nervosa and bulimia nervosa: An appraisal.

Anorexia nervosa (AN) and bulimia nervosa (BN) are eating disorders characterized by an aberrant pattern of eating behavior, relentless pursuit of thinness, an intense fear about weight gain and an altered perception of body shape. The pathobiology of eating disorders is complex. Several social, psychological and developmental phenomena are proposed to contribute to the etiology of eating disorders. The role of neuropeptide Y, corticotropin releasing hormone and leptin has also been investigated to understand the pathogenesis of eating disorders. However, most of the neuropeptide alterations noted in eating disorders are secondary to starvation. Several nonpharmacological approaches such as cognitive and behavior-based therapy and interpersonal therapy have been developed to assist weight gain and to modify the behavioral impairment associated with eating disorders. Pharmacotherapy serves as an adjunct in AN, whereas it plays a more significant role in the management of BN. Antidepressants are effective in a limited number of AN patients with comorbid depression. On the other hand, the efficacy of fluoxetine in BN patients in reducing the frequency of binge eating and in the severity of behavioral abnormalities is quite impressive. Several adjunct therapies such as prokinetics and anxiolytics have also been used in AN and BN to assist eating behavior. An insight into genetic and neurochemical abnormalities occurring in eating disorders will help to find better therapeutic agents for these disorders. (c) 2001 Prous Science. All rights reserved.

Adjunctive therapy in patients with Alzheimer's disease. A practical approach.

Alzheimer's disease (AD) primarily results in memory impairment and cognitive deficits in areas such as language, visuospatial function, calculation, praxis and judgement. However, over 30% of patients with dementia develop a group of secondary behavioural disturbances, including depression, hallucinations and delusions, agitation, insomnia and wandering. Because these secondary symptoms impair patients' function, increase their need for supervision, and often influence the decision to institutionalise them, the control of these symptoms is a priority in managing AD. Psychotropic drugs, particularly antipsychotics (neuroleptics), have been a mainstay in treating many of these symptoms, but carry a high risk of adverse effects. Patients with AD may be particularly vulnerable to adverse effects of medications because of changes in pharmacokinetics and neurotransmitter systems, related to both AD and aging. At present, treating secondary symptoms of AD is more of an art than a science. For virtually every group of symptoms, older and newer classes of medications are available, with proven efficacy in patients without dementia and less clear results in AD patients. We review current treatment options and suggest preferences for each symptom complex, based on a trade-off between efficacy and adverse effects. New agents, such as selective serotonin reuptake inhibitors and atypical antipsychotics, may herald the arrival of symptom- (and receptor-) specific drugs with minimal adverse effects.(ABSTRACT TRUNCATED AT 250 WORDS)

Social construction: vistas in clinical child and adolescent psychology.

We explore here the potentials of a social constructionist orientation to knowledge for research and clinical practice. Dialogues on social construction emphasize the communal origins of knowledge. They stress the cultural basis of knowledge claims, the significance of language, the value saturation of all knowledge, and the significance of relationships as opposed to individuals. An initial illustration of constructionism in action centers on adolescent risk behavior. Such behavior is often constructed negatively within popular writings and the social science and thus ignores the meaning of such actions to the adolescents themselves. Discourse analysis indicates that for adolescents risky behavior serves important functions of enhancing group solidarity and establishing positive identity. A second illustration, exploring the implications of constructionism for therapy, places a strong emphasis on the therapist as a collaborator in the building of meaning. Traditional investments in diagnosis and treatment are replaced with the collaborative creation of new possibilities for action.

[Antisocial behavior of adolescents and home environment--need for a multidisciplinary model].

In Swedish child and adolescent psychiatry there is a more than 60-year long tradition of using longitudinal methods in research on juvenile delinquency. Since the 1940's, results have been presented using either prospective or retrospective longitudinal designs for this purpose. Starting from genetics as scientific paradigm, new approaches including neuropsychiatry and social psychiatry showed the need for a multidisciplinary view at the border between medicine and behavioral sciences. Both Swedish and international research in the area has clearly demonstrated that factors relating to gender, maturation, resilience vs. vulnerability, the mental health of the parents, the social network and the organization of the school are of importance when trying to understand, prevent and treat juvenile delinquents. The challenge presented to today's and future researchers is to understand how the complexity of the modern western society will impact already established knowledge.

A template for unitary pattern-based nursing practice.

Unitary pattern-based practice is one creative approach to nursing intervention based on the conceptual and theoretical perspective of the Science of Unitary Human Beings. Considerations for practice were derived from the major concepts and theoretical tenets of the framework. Continued clarification and operationalization of the conceptual features in practice is warranted. A template for nursing practice with specified constituents provides a mechanism for implementing practice strategies. Processes of pattern appraisal, deliberative mutual patterning, health patterning, and evaluation were elaborated for the consideration of clinical scholars. Debate and dialogue on these issues is anticipated to further explicate the practice potential of this conceptual system.
