Children with Attention-Deficit/Hyperactivity Disorder (ADHD) present significant problems with behavioral disinhibition that often negatively affect their peer relationships. Although behavior therapies for ADHD have traditionally aimed to help parents and teachers better manage children's ADHD-related behaviors, therapy processes seldom use peer relationships to implement evidence-based behavioral principles. This article introduces Structured Dyadic Behavior Therapy as a milieu for introducing effective behavioral techniques within a socially meaningful context. Establishing collaborative behavioral goals, benchmarking, and redirection strategies are discussed to highlight how in-session dyadic processes can be used to promote more meaningful reinforcement and change for children with ADHD. Implications for improving patient care, access to care, and therapist training are also discussed.

Addiction between therapy and criminalization.

The present paper delves into the question of whether and to what extent it is appropriate to leave addiction problems between the conflicting priorities of therapy and criminalization. After outlining the issue the criminal addictive behaviour including crimes associated with drug misuse and with obtaining drugs is described. Subsequently it is discussed if and how you could make allowances for addiction-related legal insanity in the criminal law sector. Following a few remarks on the principle of "voluntary therapy instead of penal sanction" as a way to alleviate the strict law on narcotic drugs misuse a summary and an outlook with criminal-political demands complete the issue.

[Ethical aspects of human embryonic stem cell use and commercial umbilical cord blood stem cell banking. Ethical reflections on the occasion of the regulation of the European Council and Parliament on advanced therapy medicinal products].

PubMed

Virt, G

2010-01-01

The regulation of the European Council and Parliament on advanced therapy medicinal products also includes therapies with human embryonic stem cells. The use of these stem cells is controversially and heavily discussed. Contrary to the use of adult stem cells, medical and ethical problems concerning the use of human embryonic stem cells persists, because this use is based on the destruction of human life at the very beginning. The regulation foresees, therefore, subsidiarity within the European Member States. Although there are no ethical problems in principle with the use of stem cells from the umbilical cord blood, there are social ethical doubts with the banking of these stem cells for autologous use without any currently foreseeable medical advantage by commercial blood banks. Also in this case subsidiarity is valid.

Rehabilitation program for children with brachial plexus and peripheral nerve injury.

PubMed

Ramos, L E; Zell, J P

2000-03-01

An aggressive and integrated physical and occupational therapy program is essential in the treatment of congenital brachial plexus injuries and other severe upper extremity nerve injuries. This article addresses the evaluation, identification of needs, establishment of goals, and the approaches to rehabilitation treatment for patients with brachial plexus palsy and other peripheral nerve injuries. Rehabilitative therapy can preserve and build on gains made possible by medical or surgical interventions; however, therapy is vital to these children regardless of whether surgery is indicated. The therapist uses a problem-solving approach to evaluate the patient and select appropriate occupational and physical therapy treatment modalities. Therapy is continually adjusted based on each child's unique needs. An understanding of the therapy principles aids in making appropriate referrals and prescriptions, and helps to coordinate care between the therapist, pediatrician, neurologist, and surgeon.

2007-03-01

I have described the corresponding method for bullying, independence and interpersonal relationships of company/opposite sex, thinking disorders caused by suffering damage or victimization and withdrawal and violence in the family among the problems in and in response to Asperger syndrome in adolescent cases. Psychotherapy is used for bullying and interpersonal relationship problems. Cognitive therapy and protective correspondence are more effective in bullying than the exposure method. It seems to be more effective to teach and instruct the corresponding principle as well as supportive response because interpersonal relationships are likely to involve failures. Pharmacological therapy was valid in feelings of paranoia and violence. Since the disorder has been recently conceptualized in pervasive developmental disorder, the scope of the subject has increased whereas Asperger syndrome used to be diagnosed in compliance with its classic examples. Therefore, it needs to clarify diagnostic examples based on new concepts, accumulate subject examples and verify the corresponding method with evidence.

Change in interpersonal problems after cognitive agoraphobia and schema-focused therapy versus psychodynamic treatment as usual of inpatients with agoraphobia and Cluster C personality disorders.

PubMed

Gude, Tore; Hoffart, Asle

2008-04-01

The aim was to study whether patients with panic disorder with agoraphobia and co-occurring Cluster C traits would respond differently regarding change in interpersonal problems as part of their personality functioning when receiving two different treatment modalities. Two cohorts of patients were followed through three months' in-patient treatment programs and assessed at follow-up one year after end of treatment. The one cohort comprised 18 patients treated with "treatment as usual" according to psychodynamic principles, the second comprised 24 patients treated in a cognitive agoraphobia and schema-focused therapy program. Patients in the cognitive condition showed greater improvement in interpersonal problems than patients in the treatment as usual condition. Although this quasi-experimental study has serious limitations, the results may indicate that agoraphobic patients with Cluster C traits should be treated in cognitive agoraphobia and schema-focused programs rather than in psychodynamic treatment as usual programs in order to reduce their level of interpersonal problems.

Neuromechanical principles underlying movement modularity and their implications for rehabilitation

Summary Neuromechanical principles define the properties and problems that shape neural solutions for movement. Although the theoretical and experimental evidence is debated, we present arguments for consistent structures in motor patterns, i.e. motor modules, that are neuromechanical solutions for movement particular to an individual and shaped by evolutionary, developmental, and learning processes. As a consequence, motor modules may be useful in assessing sensorimotor deficits specific to an individual, and define targets for the rational development of novel rehabilitation therapies that enhance neural plasticity and sculpt motor recovery. We propose that motor module organization is disrupted and may be improved by therapy in spinal cord injury, stroke, and Parkinson’s disease. Recent studies provide insights into the yet unknown underlying neural mechanisms of motor modules, motor impairment and motor learning, and may lead to better understanding of the causal nature of modularity and its underlying neural substrates.

In this paper, we describe some central mathematical problems in medical imaging. The subject has been undergoing rapid changes driven by better hardware and software. Much of the software is based on novel methods utilizing geometric partial differential equations in conjunction with standard signal/image processing techniques as well as computer graphics facilitating man/machine interactions. As part of this enterprise, researchers have been trying to base biomedical engineering principles on rigorous mathematical foundations for the development of software methods to be integrated into complete therapy delivery systems. These systems support the more effective delivery of many image-guided procedures such as radiation therapy, biopsy, and minimally invasive surgery. We will show how mathematics may impact some of the main problems in this area, including image enhancement, registration, and segmentation. PMID:23645963

Unifying the field: developing an integrative paradigm for behavior therapy.

PubMed

Eifert, G H; Forsyth, J P; Schauss, S L

1993-06-01

The limitations of early conditioning models and treatments have led many behavior therapists to abandon conditioning principles and replace them with loosely defined cognitive theories and treatments. Systematic theory extensions to human behavior, using new concepts and processes derived from and built upon the basic principles, could have prevented the divisive debates over whether psychological dysfunctions are the results of conditioning or cognition and whether they should be treated with conditioning or cognitive techniques. Behavior therapy could also benefit from recent advances in experimental cognitive psychology that provide objective behavioral methods of studying dysfunctional processes. We suggest a unifying paradigm for explaining abnormal behavior that links and integrates different fields of study and processes that are frequently believed to be incompatible or antithetical such as biological vulnerability variables, learned behavioral repertoires, and that also links historical and current antecedents of the problem. An integrative paradigmatic behavioral approach may serve a unifying function in behavior therapy (a) by promoting an understanding of the dysfunctional processes involved in different disorders and (b) by helping clinicians conduct functional analyses that lead to theory-based, individualized, and effective treatments.

The PACE trial of cognitive behavioural therapy and graded exercise therapy for chronic fatigue syndrome/myalgic encephalomyelitis has raised serious questions about research methodology. An editorial article by Geraghty gives a fair account of the problems involved, if anything understating the case. The response by White et al. fails to address the key design flaw, of an unblinded study with subjective outcome measures, apparently demonstrating a lack of understanding of basic trial design requirements. The failure of the academic community to recognise the weakness of trials of this type suggests that a major overhaul of quality control is needed.

Currently, no evidence-based treatment is available for mood problems after stroke. We present a new psychological intervention designed to reduce depressive complaints after stroke. This intervention was based on cognitive behavioural therapy principles and was shown feasible in a pilot study. In order to meet the specific needs of stroke patients (concerning both sensori-motor, cognitive, and behavioural problems), we incorporated motivational interviewing, grief resolution, and psycho-education. We emphasised for each session to take into account the cognitive deficits of the patients (i.e. be concrete, accessible, structured, specific, and repeat information). Moreover, we augmented the psychologist-administered therapy with the contribution of an occupational or movement therapist aimed at facilitating patients' goal-setting and attainment. The intervention consisted of 12 one-hour sessions with a psychologist and three or four one-hour sessions with an occupational or movement therapist. Currently, the effectiveness of the intervention is evaluated in a randomised controlled trial. The proposed psychological treatment protocol is innovative, as it applies cognitive behavioural therapy in a stroke-specific manner; moreover, it supports goal attainment by incorporating occupational or movement therapy sessions. © The Author(s) 2014.

Cognitive-Behavioral Couple Therapies: Review of the Evidence for the Treatment of Relationship Distress, Psychopathology, and Chronic Health Conditions.

PubMed

Fischer, Melanie S; Baucom, Donald H; Cohen, Matthew J

2016-09-01

Cognitive-behavioral couple therapy (CBCT) is an approach to assisting couples that has strong empirical support for alleviating relationship distress. This paper provides a review of the empirical status of CBCT along with behavioral couple therapy (BCT), as well as the evidence for recent applications of CBCT principles to couple-based interventions for individual psychopathology and medical conditions. Several meta-analyses and major reviews have confirmed the efficacy of BCT and CBCT across trials in the United States, Europe, and Australia, and there is little evidence to support differential effectiveness of various forms of couple therapy derived from behavioral principles. A much smaller number of effectiveness studies have shown that successful implementation in community settings is possible, although effect sizes tend to be somewhat lower than those evidenced in randomized controlled trials. Adapted for individual problems, cognitive-behavioral couple-based interventions appear to be at least as effective as individual cognitive behavioral therapy (CBT) across a variety of psychological disorders, and often more effective, especially when partners are substantially involved in treatment. In addition, couple-based interventions tend to have the unique added benefit of improving relationship functioning. Findings on couple-based interventions for medical conditions are more varied and more complex to interpret given the greater range of target outcomes (psychological, relational, and medical variables). © 2016 Family Process Institute.

The Oregon Model of Behavior Family Therapy: From Intervention Design to Promoting Large-Scale System Change

Dishion, Thomas; Forgatch, Marion; Chamberlain, Patricia; Pelham, William E.

2017-01-01

This paper reviews the evolution of the Oregon model of family behavior therapy over the past four decades. Inspired by basic research on family interaction and innovation in behavior change theory, a set of intervention strategies were developed that were effective for reducing multiple forms of problem behavior in children (e.g., Patterson, Chamberlain, & Reid, 1982). Over the ensuing decades, the behavior family therapy principles were applied and adapted to promote children’s adjustment to address family formation and adaptation (Family Check-Up model), family disruption and maladaptation (Parent Management Training–Oregon model), and family attenuation and dissolution (Treatment Foster Care–Oregon model). We provide a brief overview of each intervention model and summarize randomized trials of intervention effectiveness. We review evidence on the viability of effective implementation, as well as barriers and solutions to adopting these evidence-based practices. We conclude by proposing an integrated family support system for the three models applied to the goal of reducing the prevalence of severe problem behavior, addiction, and mental problems for children and families, as well as reducing the need for costly and largely ineffective residential placements.

2011-09-01

Evidence for effectiveness of pediatric physical therapy in infants at high risk for developmental motor disorders is limited. Therefore, "Coping With and Caring for Infants With Special Needs" (COPCA), a family-centered, early intervention program, was developed. The COPCA program is based on 2 components: (1) family involvement and educational parenting and (2) the neuromotor principles of the neuronal group selection theory. The COPCA coach uses principles of coaching to encourage the family's own capacities for solving problems of daily care and incorporating variation, along with trial and error in daily activities. The purpose of this study was to evaluate whether the content of sessions of the home-based, early intervention COPCA program differs from that of traditional infant physical therapy (TIP) sessions, which in the Netherlands are largely based on neurodevelopmental treatment. The study was conducted at the University Medical Center Groningen in the Netherlands. A quantitative video analysis of therapy sessions was conducted with infants participating in a 2-arm randomized trial. Forty-six infants at high risk for developmental motor disorders were randomly assigned to receive COPCA (n=21) or TIP (n=25) between 3 and 6 months corrected age. Intervention sessions were videotaped at 4 and 6 months corrected age and analyzed with a standardized observation protocol for the classification of physical therapy actions. Outcome parameters were relative amounts of time spent on specific physical therapy actions. The content of COPCA and TIP differed substantially. For instance, in TIP sessions, more time was spent on facilitation techniques, including handling, than in COPCA sessions (29% versus 3%, respectively). During COPCA, more time was spent on family coaching and education than during TIP (16% versus 4%, respectively). The major limitation of the study was its restriction to the Netherlands, implying that findings cannot be generalized automatically to other countries. The COPCA program differs broadly from TIP as applied in the Netherlands. Studies on the effectiveness of this family-centered program are needed.

The sedentary lifestyle, common to most modern societies, has turned obesity into an increasingly prevalent and universal problem. Obesity correlates positively with many diseases and health risk factors. Medical therapies currently used to treat obesity are generally limited in terms of long-term effectiveness. Bariatric surgery has been demonstrated an effective treatment for morbid obesity. Special nursing care considerations for bariatric surgery include providing wider cuffs for blood pressure checks, preventing deep venous thrombosis and post operation dietary education in order to accommodate changes in the gastrointestinal system. The purposes of this article were to introduce obesity therapy trends as well as to share nursing care principles for those undergoing bariatric surgery.

THE HOW AND WHY OF THE MOVEMENT SYSTEM AS THE IDENTITY OF PHYSICAL THERAPY

2017-01-01

The Movement System was adopted as the identity of physical therapy as one of the 8 guiding principles accompanying the Vision Statement of 2013. At its inception physical therapy was considered more of a technical field rather than that of a professional field. Physicians were to diagnose the patient's problem and the therapist was to follow the prescription provided by the physician with the primary purpose being to relieve symptoms such as pain or muscle weakness. Even by the 1960's, the prescription became more of a referral and there was recognition that therapists were making decisions about the patient's treatment and discharge disposition. The role of the physical therapist in pathokinesiologic problems has been well accepted over the years but as insights are gained about the role of movement in musculoskeletal pain, the concept of kinesiopathologic problems is being defined. Whether the movement dysfunction is from a pathokinesiologic or a kinesiopathologic mechanisms, the underlying physiologic process is movement which is the composite action of the movement system. This article provides a brief discussion of the steps leading to promotion of the identity and the reasons that further defining and promoting the movement system as the body system for which physical therapists are responsible is necessary for the full recognition of the profession. As suggested by the kinesiopathologic concept of movement inducing pathology, physical therapists can address the cause of musculoskeletal problems and not just symptoms or consequences such as the pathoanatomic problem.

Performance improvement is a mainstay of operations management and maintenance of certification. In this study at a University Hospital inpatient rehabilitation unit, Lean management techniques were used to manage throughput of patients into and out of the inpatient rehabilitation unit. At the start of this process, the average admission time to the rehabilitation unit was 5:00 p.m., with a median time of 3:30 p.m., and no patients received therapy on the day of admission. Within 8 mos, the mean admission time was 1:22 p.m., 50% of the patients were on the rehabilitation unit by 1:00 p.m., and more than 70% of all patients received therapy on the day of admission. Negative variance from this performance was evaluated, the identification of inefficient discharges holding up admissions as a problem was identified, and a Lean workshop was initiated. Once this problem was tackled, the prime objective of 70% of patients receiving therapy on the date of admission was consistently met. Lean management tools are effective in improving throughput on an inpatient rehabilitation unit.

Psychotherapy of the victims of massive violence: countertransference and ethical issues.

PubMed

Kinzie, J D; Boehnlein, J K

1993-01-01

Psychotherapy with severely traumatized patients is a long, draining process that often produces strong countertransference reactions. It is difficult to therapeutically and ethically handle these personal responses. We feel that at different stages in therapy different ethical principles should guide the therapy. At the early stages, fidelity and nonmaleficence should be the guiding principles. As trust and confidence develop, therapists may have more personal freedom to act; beneficence, i.e., providing specific confident care then becomes the primary ethical principle. In later stages of therapy, promoting the principles of autonomy and justice come into play. As therapy further progresses, therapists' own needs, the principle of self-interest, may be utilized in the therapeutic relationship. Throughout therapeutic contacts with traumatized patients, therapists need to monitor their own needs, and find appropriate ways outside of therapy to cope with these often intense feelings. Continuing to feel therapeutically competent and ethically grounded, yet maintaining the personal strength and balance to treat traumatized patients, pose major challenges for therapists.

Since the essence of the malign process is still unknown, together with the basic causal principle (or principles?) of the pathological, malign growth, we, are not in position to apply the adequate, the only correct causal therapy with leukosis. As a consequence, we have numberous therapeutical diagrams with leukosis. As a consequence, we have numerous therapeutical diagrams in which there is adomination of pharmacological substances having cytostatic effects of anti-microbal, substitutional and symptomatical therapies. Cytostatics represent an expressedly different therapy. Various, very powerful cytostatic combinations and procedures applied with a desire to bring the patient into remission often cause the therapeutist to have another, very important problem: how to prevent the haematological complications using the cytostatic therapy, primarily the leukopenia and thrombocytopenia which, in bodies damaged by malign processes, can cause difficult complications. In order to avoid these, a series of new methods have been developed within the cytophoresis and haemotherapy. With the advent of separators of blood components it seems that the problem of selective and precise haemotherapy has been solved completely. Namely, if the components are applied precisely, in the stage when the patient lacks them in the desired concentration, the possibility of manifold therapeutical applications offer a possibility for an adequate subtitutional therapy. This paper brings forward our initial results from this field. The CENTRIFUGE-- AMINCO was used for seperation. The seperation in it takes place in a closed system (infection impossible), and thanks to special construction which simulates the internal medium of blood vessels, the mechanical decay of tangible components in the extracorporal medium has been reduced to a minimum. By means of adjustment of peristaltic pumps, the desired seperation is possible to be achieved. Concentrated components obtained by means of separation (leukocytes and thrombocytes, separated or together), have been applied with patients having leukosis once or several times, in the stage when they, due to cytostatic treatment, had very low values of these components with the existing or threatening complications. The substitional therapy has been applied with 14 patients and very efficient effects have been observed.

The major problem of current drug-based therapy is selectivity. As in other areas of science, a combined approach might improve the situation decisively. The idea is to use the pro-drug principle together with an alternating magnetic field as physical stimulus, which can be applied in a spatially and temporarily controlled manner. As a proof of principle, the neutral hydrolysis of aspirin in physiological phosphate buffer of pH 7.5 at 40 °C was chosen. The sensor and actuator system is a commercially available gold nanoparticle (NP) suspension which is approved for animal usage, stable in high concentrations and reproducibly available. Applying the alternating magnetic field of a conventional NMR magnet system accelerated the hydrolysis of aspirin in solution.

A behavior algorithm has worked since 01.10.2008. Implementation of the principles of a rational antibiotic therapy was part of the hospital antibiotic policy. is to evaluate either introductory principles of the rational antibiotic therapy, after five-year experience lived up to expectations in the range specified by the authors. Hospital microbiological maps, comparisons of antibiotic cost, specification of microbiological tests made before and after introduction of the principles of a rational antibiotic therapy have been analyzed. Annual antibiotic consumption has been counted according to the defined daily dose (DDD) index created by the WHO. After 6 years of implementation of the rational antibiotic therapy principles, the decrease in number of isolated strains which are resistant to Klebsiella pneumoniae ESBL and Acinetobacter baumanii (resistant to carbapenems) has been indicated. The number of the Pseudomonas aeruginosa isolates has increased approximately three times, and the number of resistant isolates to carbapenem has grown six times. The cost of antibiotics has been gradually decreased in 2012 in order to represent 9,66% of all drug budget (without drug programs). Detailed analysis of antibiotic consumption has showed that after the implementation of rational antibiotic therapy principles the consumption of meropenem has increased twice in comparison to the all drugs. The number of microbiological tests grew from 0,20 to 0,29 per one patient, which means material to microbiological tests has been taken from every third patient. Annual DDD index calculated on 100 person-days has been reduced from 59,552 in 2007 to 39,90 in 2009, and it is 47,88 in 2013. The principles of rational antibiotic therapy in comparison with the other elements of antibiotic policy in hospital have caused positive changes in antibiotic ordinance. 1. It is required to adhere to the principles of a rational antibiotic therapy by medical staff mainly on the administrative restriction of access to antibiotics. 2. Monitoring changes in drug resistance of hospital flora is an essential element of the principles of a rational antibiotic therapy modification.

Antibiotic therapy of community respiratory tract infections: strategies for optimal outcomes and minimized resistance emergence.

Widespread, increasing antibiotic resistance amongst the major respiratory pathogens has compromised traditional therapy of the major infective respiratory syndromes, including bacterial pneumonia and acute exacerbations of chronic bronchitis. Guidelines for antibiotic prescribing dating from the 1980s to 1990s, which attempted to address such problems, were commonly too prescriptive and difficult to apply, and took little account of end-user practice or locally prevalent resistance levels. Further confusion was caused by conflicting recommendations emanating from differing specialty groups. The evidence that such guidelines benefited either clinical outcomes or treatment costs has been disputed. They have probably had little effect on resistance emergence. We report the recommendations of an independent, multi-national, inter-disciplinary group, which met to identify principles underlying prescribing and guideline formulation in an age of increasing bacterial resistance. Unnecessary prescribing was recognized as the major factor in influencing resistance and costs. Antibiotic therapy must be limited to syndromes in which bacterial infection is the predominant cause and should attempt maximal reduction in bacterial load, with the ultimate aim of bacterial eradication. It should be appropriate in type and context of local resistance prevalence, and optimal in dosage for the pathogen(s) involved. Prescribing should be based on pharmacodynamic principles that predict efficacy, bacterial eradication and prevention of resistance emergence. Pharmacoeconomic analyses confirm that bacteriologically more effective antibiotics can reduce overall management costs, particularly with respect to consequential morbidity and hospital admission. Application of these principles should positively benefit therapeutic outcomes, resistance avoidance and management costs and will more accurately guide antibiotic choices by both individuals and formulary/guideline committees.

Although medications are the conventional medical treatment for anxiety in the perioperative period, the addition of a complementary therapy could be an effective holistic approach to providing relief from anxiety. Principle-based concept analysis. In 2015, strategic literature searches of CINHAL and PUBMED using keywords were performed. Fifty-six full text articles were assessed for eligibility. Twelve studies were used in the final analysis to clarify the concept of relief from anxiety using complementary therapies in the perioperative period. This analysis has clarified the maturity and boundaries, within the four principles of a principle-based concept analysis, of the concept of relief from anxiety using complementary therapies in the perioperative period. A greater understanding of relief from anxiety using complimentary therapies in the perioperative period as an adjunct to conventional medicine will allow perioperative nurses and anesthesia providers to modify and specify the plan of care for their surgical patients. The use of complementary therapies for relief in the perioperative period appears to be an area of promising research and treatment for patients, families and providers.

This paper describes principles underlying the evocation of emotion with music: evaluation, resonance, memory, expectancy/tension, imagination, understanding, and social functions. Each of these principles includes several subprinciples, and the framework on music-evoked emotions emerging from these principles and subprinciples is supposed to provide a starting point for a systematic, coherent, and comprehensive theory on music-evoked emotions that considers both reception and production of music, as well as the relevance of emotion-evoking principles for music therapy. © 2015 New York Academy of Sciences.

Heart failure (HF), a common sequela of cardiovascular diseases, remains a staggering clinical problem, associated with high rates of morbidity and mortality worldwide. Advances in pharmacological, interventional, and operative management have improved patient care, but these interventions are insufficient to halt the progression of HF, particularly the end-stage irreversible loss of functional cardiomyocytes. Innovative therapies that could prevent HF progression and improve the function of the failing heart are urgently needed. Following successful preclinical studies, two main strategies have emerged as potential solutions: cardiac gene therapy and cardiac regeneration through stem and precursor cell transplantation. Many potential gene- and cell-based therapies have entered into clinical studies, intending to ameliorate cardiac dysfunction in patients with advanced HF. In this review, we focus on the recent advances in cell- and gene-based therapies in the context of cardiovascular disease, emphasizing the most advanced therapies. The principles and mechanisms of action of gene and cell therapies for HF are discussed along with the limitations of current approaches. Finally, we highlight the emerging technologies that hold promise to revolutionize the biological therapies for cardiovascular diseases. Stem Cells 2017;35:1131-1140. © 2017 AlphaMed Press.

The principle of superposition, a powerful methematical technique for analyzing certain types of complex problems in many areas of science and technology, has important application in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that solutions to individual problems can be added together to obtain solutions to complex problems. This principle applies to linear systems governed by linear differential equations. This report introduces the principle of superposition as it applies to groundwater hydrology and provides background information, discussion, illustrative problems with solutions, and problems to be solved by the reader.

[Multidimensional family therapy: which influences, which specificities?].

PubMed

Bonnaire, C; Bastard, N; Couteron, J-P; Har, A; Phan, O

2014-10-01

Among illegal psycho-active drugs, cannabis is the most consumed by French adolescents. Multidimensional family therapy (MDFT) is a family-based outpatient therapy which has been developed for adolescents with drug and behavioral problems. MDFT has shown its effectiveness in adolescents with substance abuse disorders (notably cannabis abuse) not only in the United States but also in Europe (International Cannabis Need of Treatment project). MDFT is a multidisciplinary approach and an evidence-based treatment, at the crossroads of developmental psychology, ecological theories and family therapy. Its psychotherapeutic techniques find its roots in a variety of approaches which include systemic family therapy and cognitive therapy. The aims of this paper are: to describe all the backgrounds of MDFT by highlighting its characteristics; to explain how structural and strategy therapies have influenced this approach; to explore the links between MDFT, brief strategic family therapy and multi systemic family therapy; and to underline the specificities of this family therapy method. The multidimensional family therapy was created on the bases of 1) the integration of multiple therapeutic techniques stemming from various family therapy theories; and 2) studies which have shown family therapy efficiency. Several trials have shown a better efficiency of MDFT compared to group treatment, cognitive-behavioral therapy and home-based treatment. Studies have also highlighted that MDFT led to superior treatment outcomes, especially among young people with severe drug use and psychiatric co-morbidities. In the field of systemic family therapies, MDFT was influenced by: 1) the structural family therapy (S. Minuchin), 2) the strategic family theory (J. Haley), and 3) the intergenerational family therapy (Bowen and Boszormenyi-Nagy). MDFT has specific aspects: MDFT therapists think in a multidimensional perspective (because an adolescent's drug abuse is a multidimensional disorder), they work with the system and the subsystem, focusing on the emotional expression and the parental and adolescent enactment (a principle of change and intervention). MDFT includes four modules (adolescent, parent, family interaction, and extra-familial systems) in three steps (1) build the foundation, (2) prompt action and change by working the themes, and (3) seal the changes and exit). The supervision philosophy and methodology is also based on the principle of multidimensionality. Indeed, many different supervision methods are used in a coordinated way to produce the required adherence and clinical skill (written case conceptualizations, videotape presentation and live supervision). Family vulnerability and chronicity factors are a major challenge of modern research. MDFT questions the reciprocal adjustments that have to be made by the subject and his/her familial environment. It also helps to clarify the therapeutic interventions in order to enhance better adolescent development. For this purpose, MDFT offers a specific therapeutic frame, for it is a family therapy focused on adolescents with cannabis abuse problems. Its action and questioning on parental practices and adolescents lead to better psycho-educational support. It focuses the therapeutic process on emotions and family capacity for change.

Stegemöller, Elizabeth L

2014-01-01

Given that music therapists work across a wide range of disabilities, it is important that therapists have at least a fundamental understanding of the neurophysiology associated with the client/patient populations that they serve. Yet, there is a large gap of evidence regarding the neurophysiological changes associated with applying music as therapy. The purpose of this article is to provide music therapists with a general background in neuroplasticity principles that can be applied to the use of music therapy with multiple populations. This article will review literature on neuroplasticity and literature supporting the specific attributes of music therapy that apply to neuroplasticity. Finally, examples of how to use neuroplasticity principles to explain and support clinical music therapy will be provided. Using the material presented in this review, music therapists will be equipped with information to effectively communicate why music therapy works using three neuroplasticity principles; increase in dopamine, neural synchrony, and a clear signal. Music therapy is a powerful tool to enhance neuroplasticity in the brain. © the American Music Therapy Association 2014. All rights reserved.

Nonsteroidal anti-inflammatory drugs (NSAIDs) represent class of medicines which is wide concerning chemical structure and mechanism of action. In the light of contradictory data on efficacy and safety of NSAID in cardiovascular patients selection of most appropriate NSAID (basing on profile of efficacy and safety) in patients receiving continuous therapy with low dose aspirin appears to be a problem. In this paper we discuss peculiarities of drug interaction between cyclooxygenase inhibitors and acetylsalicylic acid, and principles of selection of adequate NSAI.

Applying principles of intercultural communication to personality disorder therapy.

PubMed

Leising, Daniel

2008-09-01

Psychotherapy with patients who were diagnosed with a personality disorder bears a strong resemblance to intercultural communication. I suggest conceptualizing the situation of a patient with a personality disorder as being similar to that of an overseas traveller. Like the traveller, the patient faces the task of getting along in a social environment that does not share many of his or her ingrained values regarding 'appropriate' interpersonal behaviour. In order to reduce the potential for misunderstandings and interpersonal problems, the patient would benefit from (a) learning about the culturally accepted rules of interacting and (b) partly adopting those rules. Borrowing from training manuals for intercultural communication, I suggest a number of therapeutic principles that specifically address the discrepancies between the patient's habits and internalized values, and the cultural conventions that govern the social environment in which the patient lives.

Palliative care, public health and justice: setting priorities in resource poor countries.

PubMed

Blinderman, Craig

2009-12-01

Many countries have not considered palliative care a public health problem. With limited resources, disease-oriented therapies and prevention measures take priority. In this paper, I intend to describe the moral framework for considering palliative care as a public health priority in resource-poor countries. A distributive theory of justice for health care should consider integrative palliative care as morally required as it contributes to improving normal functioning and preserving opportunities for the individual. For patients requiring terminal care, we are guided less by principles of justice and more by the duty to relieve suffering and society's commitment to protecting the professional's obligation to uphold principles of beneficence, compassion and non-abandonment. A fair deliberation process is necessary to allow these strong moral commitments to serve as reasons when setting priorities in resource poor countries.

Is Principled Pragmatism a Viable Framework for Addressing Complex Problems?

NASA Astrophysics Data System (ADS)

Islam, S.

2017-12-01

Complex water problems are connected with many competing and often conflicting values, interests, and tools. These problems can't be addressed through simply applying dogmatic principles or a deal-making pragmatic approach. Because these problems are interconnected and interdependent, a final solution can't be pre-specified. Any intervention to a complex problem requires attention to both principles and pragmatism. Strict adherence to principles without pragmatism is often not actionable; pure pragmatism exercised without guiding principles is not sustainable. In a colloquial sense, pragmatism is often taken to suggest practical, opportunistic, and expedient approaches at the expense of principles. This perception appears to be rooted in the dichotomy between "being pragmatic" and "being ideological". The notion of principled pragmatism attempts to get away from this duality by focusing on how to make ideas clear and actionable. In other words, how to connect our thoughts to action given the context, constraints, and capacity. Principled pragmatism - rooted in equity and sustainability as guiding principles for water management - approach attempts to synthesize symbolic aspirations with realistic assessment to chart a trajectory of actionable subset of implementable solutions. Case studies from the Ganges Basin will show the utility of principled pragmatism for water management in a changing world.

[Chronic fatigue syndrome in a cognitive perspective. A therapeutic model].

PubMed

d'Elia, Giacomo

2004-01-29

The cognitive approach to the treatment of chronic fatigue syndrome (CSF) is based on a multifactor etiological hypothesis, i.e. inaccurate beliefs and attitudes to the illness interact with pathophysiological processes, ineffective coping behaviours, negative states of mood, social problem, to perpetuate the illness. Patients suffering from CFS are supposed to be hypervigilant to somatic sensations and to interpret them as signs of impending physical catastrophe. The aim of the this paper is to describe the clinical implementation of principles of cognitive therapy in the treatment of CFS. Basic to the treatment approach is a collaborative, listening and empathic attitude, sensitive to the patient's personal beliefs and potential threats to self-esteem. The aim is to develop more useful, functional, formulations of the illness. The patient and the therapist work together to look at how the patient thinks about herself/himself and the illness, detect unhelpful attitudes, thoughts and mental images about the illness, and to make them accessible to Socratic reasoning. Graded behavioural interventions are planned in order to disconfirm unhelpful beliefs and reverse the spiral of tiredness, demoralization and reduced activity. The treatment is structured according to the general principles of cognitive therapy.

The problem of 'thick in status, thin in content' in Beauchamp and Childress' principlism.

PubMed

Lee, Marvin J H

2010-09-01

For many, Thomas Beauchamp and James Childress have elaborated moral reasoning by using the four principles whereby all substantive problems of medical ethics (and of ethics more generally) can be properly analysed and cogent philosophical solutions for the problems can be found. It seems that their 'principlism' gets updated, with better features being added during the course of the six editions of Principles of Biomedical Ethics. Nonetheless, Beauchamp and Childress seem to have been losing their way when it comes to the common-morality justification, which is the epistemological (and perhaps metaphysical) backbone of their method, and this is shown more vividly in their most recent (2009) edition of Principles of Biomedical Ethics. The author points out what he calls the problem of 'thick in status, thin in content' in principlism. The problem exists because principlism cannot adequately explain how the prescriptive sense of common morality it supports is consistent with the existence of what Beauchamp and Childress call the 'legitimate moral diversity in the world'. Because of this problem, first, the practical end that principlism allegedly accomplishes (ie, providing practical moral guidelines in a relatively 'thick' content, based on common morality) is frustrated, and, second, principlism makes itself the method of common morality de jure and of moral pluralism de facto.

Ethical hot spots of combined individual and group therapy: applying four ethical systems.

PubMed

Brabender, Virginia M; Fallon, April

2009-01-01

Abstract Combined therapy presents ethical quandaries that occur in individual psychotherapy and group psychotherapy, and dilemmas specifically associated with their integration. This paper examines two types of ethical frameworks (a classical principle-based framework and a set of context-based frameworks) for addressing the ethical hot spots of combined therapy: self-referral, transfer of information, and termination. The principle-based approach enables the practitioner to see what core values may be served or violated by different courses of action in combined therapy dilemmas. Yet, the therapist is more likely to do justice to the complexity and richness of the combined therapy situation by supplementing a principle analysis with three additional ethical frameworks. These approaches are: virtue ethics, feminist ethics, and casuistry. An analysis of three vignettes illustrates how these contrasting ethical models not only expand the range of features to which the therapist attends but also the array of solutions the therapist generates.

Continuous subcutaneous insulin infusion therapy for Type 1 diabetes mellitus in children.

Mavinkurve, M; Quinn, A; O'Gorman, C S

2016-05-01

Continuous subcutaneous insulin pump therapy (CSII or pump therapy) is a well-recognised treatment option for Type 1 diabetes mellitus (T1DM) in paediatrics. It is especially suited to children because it optimises control by improving flexibility across age-specific lifestyles. The NICE guidelines (2008) recognise that pump therapy is advantageous and that it should be utilised to deliver best practice. In Ireland, the National Clinical Program for Diabetes will increase the availability and uptake of CSII in children and thus more clinicians are likely to encounter children using CSII therapy. This is a narrative review which discusses the basic principles of pump therapy and focuses on aspects of practical management. Insulin pump management involves some basic yet important principles which optimise the care of diabetes in children. This review addresses the principles of insulin pump management in children which all health care professionals involved in caring for the child with diabetes, shoud be familiar with.

A weak Hamiltonian finite element method for optimal control problems

Hodges, Dewey H.; Bless, Robert R.

1989-01-01

A temporal finite element method based on a mixed form of the Hamiltonian weak principle is developed for dynamics and optimal control problems. The mixed form of Hamilton's weak principle contains both displacements and momenta as primary variables that are expanded in terms of nodal values and simple polynomial shape functions. Unlike other forms of Hamilton's principle, however, time derivatives of the momenta and displacements do not appear therein; instead, only the virtual momenta and virtual displacements are differentiated with respect to time. Based on the duality that is observed to exist between the mixed form of Hamilton's weak principle and variational principles governing classical optimal control problems, a temporal finite element formulation of the latter can be developed in a rather straightforward manner. Several well-known problems in dynamics and optimal control are illustrated. The example dynamics problem involves a time-marching problem. As optimal control examples, elementary trajectory optimization problems are treated.

2015-01-01

Improvisational methods of music therapy have been increasingly applied in the treatment of individuals with autism spectrum disorder (ASD) over the past decades in many countries worldwide. This study aimed at developing treatment guidelines based on the most important common characteristics of improvisational music therapy (IMT) with children affected by ASD as applied across various countries and theoretical backgrounds. After initial development of treatment principle items, a survey among music therapy professionals in 10 countries and focus group workshops with experienced clinicians in three countries were conducted to evaluate the items and formulate revised treatment guidelines. To check usability, a treatment fidelity assessment tool was subsequently used to rate therapy excerpts. Survey findings and feedback from the focus groups corroborated most of the initial principles for IMT in the context of children with ASD. Unique and essential principles include facilitating musical and emotional attunement, musically scaffolding the flow of interaction, and tapping into the shared history of musical interaction between child and therapist. Raters successfully used the tool to evaluate treatment adherence and competence. Summarizing an international consensus about core principles of improvisational approaches in music therapy for children with ASD, these treatment guidelines may be applied in diverse theoretical models of music therapy. They can be used to assess treatment fidelity, and may be applied to facilitate future research, clinical practice, and training. © the American Music Therapy Association 2015. All rights reserved.

2009-01-01

Background Research ethics have become universal in their principles through international agreements. The standardization of regulations facilitates the internationalization of research concerning drugs. However, in so-called observational studies (i.e. from data collected retrospectively or prospectively, obtained without any additional therapy or monitoring procedure), the modalities used for applying the main principles vary from one country to the other. This situation may entail problems for the conduct of multi-centric international studies, as well as for the publication of results if the authors and editors come from countries governed by different regulations. In particular, several French observational studies were rejected or retracted by United States peer reviewed journals, because their protocols have not been submitted to an Institutional Review Board/Independent Ethics Committee (IRB/IEC). Methods national legislation case analysis Results In accordance with European regulation, French observational studies from data obtained without any additional therapy or monitoring procedure, do not need the approval of an IRB/IEC. Nevertheless, these researches are neither exempt from scientific opinion nor from ethical and legal authorization. Conclusion We wish to demonstrate through the study of this example that different bodies of law can provide equivalent levels of protection that respect the same ethical principles. Our purpose in writing this paper was to encourage public bodies, scientific journals, and researchers to gain a better understanding of the various sets of specific national regulations and to speak a common language.

Using an isomorphic problem pair to learn introductory physics: Transferring from a two-step problem to a three-step problem

NASA Astrophysics Data System (ADS)

Lin, Shih-Yin; Singh, Chandralekha

2013-12-01

In this study, we examine introductory physics students’ ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. 382 students from a calculus-based and an algebra-based introductory physics course were administered a quiz in the recitation in which they had to learn from a solved problem provided and take advantage of what they learned from it to solve another isomorphic problem (which we call the quiz problem). The solved problem provided has two subproblems while the quiz problem has three subproblems, which is known from previous research to be challenging for introductory students. In addition to the solved problem, students also received extra scaffolding supports that were intended to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. The data analysis suggests that students had great difficulty in transferring what they learned from a two-step problem to a three-step problem. Although most students were able to learn from the solved problem to some extent with the scaffolding provided and invoke the relevant principles in the quiz problem, they were not necessarily able to apply the principles correctly. We also conducted think-aloud interviews with six introductory students in order to understand in depth the difficulties they had and explore strategies to provide better scaffolding. The interviews suggest that students often superficially mapped the principles employed in the solved problem to the quiz problem without necessarily understanding the governing conditions underlying each principle and examining the applicability of the principle in the new situation in an in-depth manner. Findings suggest that more scaffolding is needed to help students in transferring from a two-step problem to a three-step problem and applying the physics principles appropriately. We outline a few possible strategies for future investigation.

Estimating Tissue Iron Burden: Current Status and Future Prospects

PubMed Central

Wood, John C.

2015-01-01

SUMMARY Iron overload is becoming an increasing problem as haemoglobinopathy patients gain greater access to good medical care and as therapies for myelodysplastic syndromes improve. Therapeutic options for iron chelation therapy have increased and many patients now receive combination therapies. However, optimal utilization of iron chelation therapy requires knowledge not only of the total body iron burden but the relative iron distribution among the different organs. The physiological basis for extrahepatic iron deposition is presented in order to help identify patients at highest risk for cardiac and endocrine complications. This manuscript reviews the current state of the art for monitoring global iron overload status as well as its compartmentalization. Plasma markers, computerized tomography, liver biopsy, magnetic susceptibility devices and magnetic resonance imaging (MRI) techniques are all discussed but MRI has come to dominate clinical practice. The potential impact of recent pancreatic and pituitary MRI studies on clinical practice are discussed as well as other works-in-progress. Clinical protocols are derived from experience in haemoglobinopathies but may provide useful guiding principles for other iron overload disorders, such as myelodysplastic syndromes. PMID:25765344

Minimization principles for the coupled problem of Darcy-Biot-type fluid transport in porous media linked to phase field modeling of fracture

NASA Astrophysics Data System (ADS)

Miehe, Christian; Mauthe, Steffen; Teichtmeister, Stephan

2015-09-01

This work develops new minimization and saddle point principles for the coupled problem of Darcy-Biot-type fluid transport in porous media at fracture. It shows that the quasi-static problem of elastically deforming, fluid-saturated porous media is related to a minimization principle for the evolution problem. This two-field principle determines the rate of deformation and the fluid mass flux vector. It provides a canonically compact model structure, where the stress equilibrium and the inverse Darcy's law appear as the Euler equations of a variational statement. A Legendre transformation of the dissipation potential relates the minimization principle to a characteristic three field saddle point principle, whose Euler equations determine the evolutions of deformation and fluid content as well as Darcy's law. A further geometric assumption results in modified variational principles for a simplified theory, where the fluid content is linked to the volumetric deformation. The existence of these variational principles underlines inherent symmetries of Darcy-Biot theories of porous media. This can be exploited in the numerical implementation by the construction of time- and space-discrete variational principles, which fully determine the update problems of typical time stepping schemes. Here, the proposed minimization principle for the coupled problem is advantageous with regard to a new unconstrained stable finite element design, while space discretizations of the saddle point principles are constrained by the LBB condition. The variational principles developed provide the most fundamental approach to the discretization of nonlinear fluid-structure interactions, showing symmetric systems in algebraic update procedures. They also provide an excellent starting point for extensions towards more complex problems. This is demonstrated by developing a minimization principle for a phase field description of fracture in fluid-saturated porous media. It is designed for an incorporation of alternative crack driving forces, such as a convenient criterion in terms of the effective stress. The proposed setting provides a modeling framework for the analysis of complex problems such as hydraulic fracture. This is demonstrated by a spectrum of model simulations.

Enhancing the Therapy Experience Using Principles of Video Game Design.

Folkins, John Wm; Brackenbury, Tim; Krause, Miriam; Haviland, Allison

2016-02-01

This article considers the potential benefits that applying design principles from contemporary video games may have on enhancing therapy experiences. Six principles of video game design are presented, and their relevance for enriching clinical experiences is discussed. The motivational and learning benefits of each design principle have been discussed in the education literature as having positive impacts on student motivation and learning and are related here to aspects of clinical practice. The essential experience principle suggests connecting all aspects of the experience around a central emotion or cognitive connection. The discovery principle promotes indirect learning in focused environments. The risk-taking principle addresses the uncertainties clients face when attempting newly learned skills in novel situations. The generalization principle encourages multiple opportunities for skill transfer. The reward system principle directly relates to the scaffolding of frequent and varied feedback in treatment. Last, the identity principle can assist clients in using their newly learned communication skills to redefine self-perceptions. These principles highlight areas for research and interventions that may be used to reinforce or advance current practice.

Externalizing problems, which are the main reason for youth referrals to mental health agencies, are highly persistent and predict a range of negative outcomes. Youths with externalizing problems are also frequently comorbid with anxiety. Among the most widely recognized evidence-based treatments is cognitive behavioral therapy (CBT). Although CBT principles seem to be sound, effect sizes remain moderate, suggesting improvements could be made to this conventional treatment approach. The main premise of the current pilot study is to investigate the feasibility of implementing a videogame intervention ("Dojo" [Gamedesk, Los Angeles, CA]) that incorporates CBT principles and aims to address the limitations of conventional CBT delivery models, with the ultimate goal of improving outcomes for this difficult-to-treat population. "Dojo" is an emotion management game that helps youths to recognize and control their physiological and emotional arousal. We explored the implementation and user experience of "Dojo" in a sample of eight adolescents in residential treatment for both externalizing and anxiety problems. Participants attended all sessions without complaints. They evaluated "Dojo" very positively and exhibited high compliance during the training sessions. We encountered some problems with session scheduling and obtaining mentor reports. Quantitative data show the predicted decrease in three out of four measurements. The smooth implementation, high user satisfaction, high self-reported compliance during training sessions, and initial outcome results all indicate the high potential "Dojo" holds as an innovative intervention. If additional rigorously designed randomized controlled trials prove to be successful, "Dojo" can be a cost-effective way to engage high-risk youths in effective intervention.

Currently, patients suffering from diseased and injured organs can be treated with transplanted organs. However, there is a severe shortage of donor organs that is worsening yearly as the population ages and new cases of organ failure increase. Scientists in the field of regenerative medicine and tissue engineering are now applying the principles of cell transplantation, material science, and bioengineering to construct biological substitutes that will restore and maintain normal function in diseased and injured tissues. The stem cell field is also advancing rapidly, opening new avenues for this type of therapy. For example, therapeutic cloning and cellular reprogramming may one day provide a potentially limitless source of cells for tissue engineering applications. Although stem cells are still in the research phase, some therapies arising from tissue engineering endeavors have already entered the clinical setting successfully, indicating the promise regenerative medicine holds for the future.

The link between cholesterol levels and atherosclerotic cardiovascular disease (ASCVD) is well-established. In Singapore, there is an increasing prevalence of risk factors for ASCVD. Like many Asian countries, Singapore's population is rapidly ageing and increasingly sedentary, which predisposes individuals to chronic health problems. Current international and local guidelines recommend statin therapy for the primary and secondary prevention of ASCVD. However, despite the effectiveness of statin therapy, some studies have highlighted that Asian patients with cardiovascular disease are not achieving target lipid goals. Furthermore, it is widely believed that the responses of Asians (both patients and physicians) to statin therapy are different from those of their Western counterparts. Experts convened in 2014 to determine the impact of current guidelines on clinical practice in Singapore. This review summarises the key findings and recommendations of these guidelines, and presents key principles to aid clinicians to manage the cardiovascular risk of their patients more effectively.

Progress in medical diagnosis and therapy has raised new problems with far-reaching ethical implications. Medicine must remain a profession and not become a business. Textbooks must address ethical problems in the context of health care decisions and not restrict themselves to pathophysiology and practical therapeutics alone. The relative roles of the principles of autonomy, non-maleficence, beneficence, and justice must be balanced and appropriately applied to individual situations in biomedical ethics. When therapy becomes futile and the suffering of the patient does not justify any anticipated benefit, the patient (and/or patient surrogate) may request withholding or even withdrawing life-prolonging interventions. In the persistent vegetative state, even nutritional support by an unnatural (tube) route may ethically be denied at the patient's (or surrogate's) informed decision. New areas of ethical evaluation have been raised by the desire of some individuals to prolongation of their lives at high expense to the society such that other individuals are denied services because of limitation of available resources. There has been a long-standing conflict of interest between the acceptance by physicians and/or medical institutions of money or gifts from pharmaceutical companies whose drugs they prescribe, stock, or sell. This practice increases the cost of the drugs and is, in effect, a "sick tax," which is morally wrong. PMID:1519374

Evaluation of the knowledge on CHD risk factors in selected Lódź population was made. Realization of primary and secondary CHD prevention principles was assessed. Over 20% of patients with CHD and over 38% of subjects without CHD did not realize the prevention principles. Hypolipemic therapy was effective only in 44.21% of patients with CHD and 35.9% of subjects without CHD. Antihypertensive therapy was successful in about 55% of patients with CHD and 35% of subjects without CHD. The results of our study have shown low effectiveness of both CHD prevention principles realization and hipolipemic and antihypertensive therapy in selected Lódź population.

Optimal control of multiplicative control systems arising from cancer therapy

This study deals with ways of curtailing the rapid growth of cancer cell populations. The performance functional that measures the size of the population at the terminal time as well as the control effort is devised. With use of the discrete maximum principle, the Hamiltonian for this problem is determined and the condition for optimal solutions are developed. The optimal strategy is shown to be a bang-bang control. It is shown that the optimal control for this problem must be on the vertices of an N-dimensional cube contained in the N-dimensional Euclidean space. An algorithm for obtaining a local minimum of the performance function in an orderly fashion is developed. Application of the algorithm to the design of antitumor drug and X-irradiation schedule is discussed.

Background There is a paucity of research on psychosocial treatments for depression in adults with intellectual disability (ID). In this pilot study, we explored the efficacy of a group CBT treatment that involved a caregiver component in adults with mild ID with a depressive disorder. Method Sixteen adults with mild ID and a depressive disorder participated in a 10-week group CBT treatment and 8 adults with mild ID with a depressive disorder served as a treatment as usual (TAU) control group. Adults with mild ID and caregivers completed measures of depressive symptoms, behavior problems, and social skills at pre-treatment, post-treatment, and a 3-month follow-up. Adults with mild ID also completed a series of tasks to measure their understanding of the principles of cognitive therapy pre- and post-treatment. Results The CBT group demonstrated significant decreases in depressive symptoms and behavior problems from pre-treatment to post-treatment and these effects were maintained at a 3-month follow-up. The CBT group demonstrated significant improvements in their ability to infer emotions and thoughts based on various situation-thought-emotion pairings from pre-treatment to post-treatment. Conclusions Findings indicate that adults with mild ID with a depressive disorder benefitted from a group CBT treatment with a caregiver component. Moreover, adults with mild ID appeared to benefit, at least in part, from the cognitive therapy components of the treatment, in addition to the behavior therapy components. PMID:26925187

TOPICAL REVIEW: A review of dosimetry studies on external-beam radiation treatment with respect to second cancer induction

Xu, X. George; Bednarz, Bryan; Paganetti, Harald

2008-07-01

It has been long known that patients treated with ionizing radiation carry a risk of developing a second cancer in their lifetimes. Factors contributing to the recently renewed concern about the second cancer include improved cancer survival rate, younger patient population as well as emerging treatment modalities such as intensity-modulated radiation treatment (IMRT) and proton therapy that can potentially elevate secondary exposures to healthy tissues distant from the target volume. In the past 30 years, external-beam treatment technologies have evolved significantly, and a large amount of data exist but appear to be difficult to comprehend and compare. This review article aims to provide readers with an understanding of the principles and methods related to scattered doses in radiation therapy by summarizing a large collection of dosimetry and clinical studies. Basic concepts and terminology are introduced at the beginning. That is followed by a comprehensive review of dosimetry studies for external-beam treatment modalities including classical radiation therapy, 3D-conformal x-ray therapy, intensity-modulated x-ray therapy (IMRT and tomotherapy) and proton therapy. Selected clinical data on second cancer induction among radiotherapy patients are also covered. Problems in past studies and controversial issues are discussed. The needs for future studies are presented at the end.

The most important trends and developments in recent propolis research are outlined: biological studies performed with chemically characterized samples, bioassay-guided studies of active principles and comparative biological studies of propolis of different origin and chemical composition. These types of studies are extremely valuable with respect to propolis standardization and practical applications in therapy. They will allow scientists to connect a particular chemical propolis type to a specific type of biological activity and formulate recommendations for practitioners. PMID:15841275

Five analogies between a King's Speech treatment and contemporary play therapies.

PubMed

Terr, Lenore C

2012-01-01

Psychiatric patients frequently respond positively to play therapy, which may rely on psychoanalytic, Jungian, cognitive-behavioral, familial, school-based, or other theories. I wished to determine if there were unifying principles that tie together these various types of play treatments. The fact-based film, The King's Speech, vividly illustrates play utilized by Lionel Logue in his speech treatment (1926-1939) of the future King of England. In the film I found five analogies to the play therapy I employ in office practice. The play scenes in The King's Speech point to five unifying principles among contemporary play therapies: (1) the crucial nature of the relationship, (2) the centrality of having fun, (3) the occasional reliance on others, (4) the interjection of pithy talk, and (5) the usefulness of a little drama. No matter what theory a play therapist ascribes to, these five unifying principles should be kept in mind during treatment.

The Power Equity Guide: attending to gender in family therapy.

In the past two decades, feminist scholars have challenged the field of family therapy to incorporate the organizing principle of gender in its theory, practice, and training. In this paper, we introduce a training, research, and therapeutic tool that provides guidance for addressing or observing gender and power differentials in the practice of family therapy. As a training tool, the Power Equity Guide helps trainees to translate their theoretical understanding of feminist principles into specific behaviors in therapy. Researchers and supervisors can use the Power Equity Guide to evaluate the practice of gender-informed family therapy. We also provide specific suggestions for its use by trainers, supervisors, therapists, and researchers.

Design of clinical trials for therapeutic cancer vaccines development.

Mackiewicz, Jacek; Mackiewicz, Andrzej

2009-12-25

Advances in molecular and cellular biology as well as biotechnology led to definition of a group of drugs referred to as medicinal products of advanced technologies. It includes gene therapy products, somatic cell therapeutics and tissue engineering. Therapeutic cancer vaccines including whole cell tumor cells vaccines or gene modified whole cells belong to somatic therapeutics and/or gene therapy products category. The drug development is a multistep complex process. It comprises of two phases: preclinical and clinical. Guidelines on preclinical testing of cell based immunotherapy medicinal products have been defined by regulatory agencies and are available. However, clinical testing of therapeutic cancer vaccines is still under debate. It presents a serious problem since recently clinical efficacy of the number of cancer vaccines has been demonstrated that focused a lot of public attention. In general clinical testing in the current form is very expensive, time consuming and poorly designed what may lead to overlooking of products clinically beneficial for patients. Accordingly regulatory authorities and researches including Cancer Vaccine Clinical Trial Working Group proposed three regulatory solutions to facilitate clinical development of cancer vaccines: cost-recovery program, conditional marketing authorization, and a new development paradigm. Paradigm includes a model in which cancer vaccines are investigated in two types of clinical trials: proof-of-principle and efficacy. The proof-of-principle trial objectives are: safety; dose selection and schedule of vaccination; and demonstration of proof-of-principle. Efficacy trials are randomized clinical trials with objectives of demonstrating clinical benefit either directly or through a surrogate. The clinical end points are still under debate.

Dyck, I

1993-08-01

Principles of occupational therapy practice make the profession an important potential partner in health promotion initiatives for immigrant groups. Health promotion embodies the principles of self-definition of health needs by target groups, and working with a community in initiating and supporting programmes. This paper discusses the implications of an exploratory study of the daily activities of immigrant Indo-Canadian mothers for translating health promotion principles into practice. The research process and an analysis of interviews conducted with the women suggest factors to consider in using a health promotion framework with immigrants who have experienced social and economic dislocation through the immigration process. Discussion of household structure, divisions of labour, childcare strategies, and parenting concerns raises issues requiring particular attention in sharing occupational therapy skills and knowledge with ethnocultural communities.

Control of Finite-State, Finite Memory Stochastic Systems

Sandell, Nils R.

1974-01-01

A generalized problem of stochastic control is discussed in which multiple controllers with different data bases are present. The vehicle for the investigation is the finite state, finite memory (FSFM) stochastic control problem. Optimality conditions are obtained by deriving an equivalent deterministic optimal control problem. A FSFM minimum principle is obtained via the equivalent deterministic problem. The minimum principle suggests the development of a numerical optimization algorithm, the min-H algorithm. The relationship between the sufficiency of the minimum principle and the informational properties of the problem are investigated. A problem of hypothesis testing with 1-bit memory is investigated to illustrate the application of control theoretic techniques to information processing problems.

From geometry to algebra and vice versa: Realistic mathematics education principles for analyzing geometry tasks

Jupri, Al

2017-04-01

In this article we address how Realistic Mathematics Education (RME) principles, including the intertwinement and the reality principles, are used to analyze geometry tasks. To do so, we carried out three phases of a small-scale study. First we analyzed four geometry problems - considered as tasks inviting the use of problem solving and reasoning skills - theoretically in the light of the RME principles. Second, we tested two problems to 31 undergraduate students of mathematics education program and other two problems to 16 master students of primary mathematics education program. Finally, we analyzed student written work and compared these empirical to the theoretical results. We found that there are discrepancies between what we expected theoretically and what occurred empirically in terms of mathematization and of intertwinement of mathematical concepts from geometry to algebra and vice versa. We conclude that the RME principles provide a fruitful framework for analyzing geometry tasks that, for instance, are intended for assessing student problem solving and reasoning skills.

In the last decades, children's understanding of mathematical principles has become an important research topic. Different from the commutativity and inversion principles, only few studies have focused on children's understanding of the addition/subtraction complement principle (if a - b = c, then c + b = a), mainly relying on verbal techniques. This contribution aimed at deepening our understanding of children's knowledge of the addition/subtraction complement principle, combining verbal and non-verbal techniques. Participants were 67 third and fourth graders (9- to 10-year-olds). Children solved two tasks in which verbal reports as well as accuracy and speed data were collected. These two tasks differed only in the order of the problems and the instructions. In the looking-back task, children were told that sometimes the preceding problem might help to answer the next problem. In the baseline task, no helpful preceding items were offered. The looking-back task included 10 trigger-target problem pairs on the complement relation. Children verbally reported looking back on about 40% of all target problems in the looking-back task; the target problems were also solved faster and more accurately than in the baseline task. These results suggest that children used their understanding of the complement principle. The verbal and non-verbal data were highly correlated. This study complements previous work on children's understanding of mathematical principles by highlighting interindividual differences in 9- to 10-year-olds' understanding of the complement principle and indicating the potential of combining verbal and non-verbal techniques to investigate (the acquisition of) this understanding. © 2016 The British Psychological Society.

The growth of chronic conditions: Search for solutions to the problem.

PubMed

Mednis, Dmitry

2017-06-25

The chronic conditions growth is determined by an increase of cases of adaptive system imbalance following a recent disease. One of its most significant causes is decrease of crisis importance (a stage of disease) as a moderator of a qualitative changeover of an adaptive system. The contemporary treatment methods increase efficiency of pre-crises adaptive responses, but simultaneously they equalize the crisis to a level, which is insufficient for complete after-crisis alignment of body defenses. But the crisis is the very key to a solution to a chronic conditions problem. One of the ways of the problem solving is medical interventions, which cause sparing provocation crisis and a successive changeover of an adaptive system. Based on this it is worth reviewing critically, studying and developing the existing experience of bio-regulatory therapy, where the principle of sparing provocation is often used. The new term definitions, such as "medical intervention", "health problems", "crisis" are described in terms of biomedicine. The patients and physicians should be motivated to deal with chronic conditions correction and the aforesaid sets new tasks before a health care system.

Applied Behavior Analysis, Autism, and Occupational Therapy: A Search for Understanding.

Welch, Christie D; Polatajko, H J

2016-01-01

Occupational therapists strive to be mindful, competent practitioners and continuously look for ways to improve practice. Applied behavior analysis (ABA) has strong evidence of effectiveness in helping people with autism achieve goals, yet it does not seem to be implemented in occupational therapy practice. To better understand whether ABA could be an evidence-based option to expand occupational therapy practice, the authors conducted an iterative, multiphase investigation of relevant literature. Findings suggest that occupational therapists apply developmental and sensory approaches to autism treatment. The occupational therapy literature does not reflect any use of ABA despite its strong evidence base. Occupational therapists may currently avoid using ABA principles because of a perception that ABA is not client centered. ABA principles and occupational therapy are compatible, and the two could work synergistically. Copyright © 2016 by the American Occupational Therapy Association, Inc.

Purpose behind developing these guidelines: Over one decade ago, the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2006" (Japan Thyroid Association (JTA)) were published as the standard drug therapy protocol for Graves' disease. The "Guidelines for the Treatment of Childhood-Onset Graves' Disease with Antithyroid Drug in Japan, 2008" were published to provide guidance on the treatment of pediatric patients. Based on new evidence, a revised version of the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2006" (JTA) was published in 2011, combined with the "Handbook of Radioiodine Therapy for Graves' Disease 2007" (JTA). Subsequently, newer findings on pediatric Graves' disease have been reported. Propylthiouracil (PTU)-induced serious hepatopathy is an important problem in pediatric patients. The American Thyroid Association's guidelines suggest that, in principle, physicians must not administer PTU to children. On the other hand, the "Guidelines for the Treatment of Graves' Disease with Antithyroid Drug, 2011" (JTA) state that radioiodine therapy is no longer considered a "fundamental contraindication" in children. Therefore, the "Guidelines for the Treatment of Childhood-Onset Graves' Disease with Antithyroid Drug in Japan, 2008" required revision.

The government of Zimbabwe began providing antiretroviral therapy (ART) to People Living with HIV/AIDS (PLHIV) in public institutions in 2004. In Midlands province two clinics constituted the most active HIV care service points, with patients being followed up through a comprehensive patient monitoring and tracking system which captured specific patient variables and outcomes over time. The data from 2006 to 2011 were subjected to analysis to answer specific research questions and this case study is based on that analysis. The goal of this case study is to build participants' capacity to undertake secondary data analysis and interpretation using a dataset for HIV antiretroviral therapy in Zimbabwe and to draw conclusions which inform recommendations. Case studies in applied epidemiology allow students to practice applying epidemiologic skills in the classroom to address real-world public health problems. Case studies as a vital component of an applied epidemiology curriculum are instrumental in reinforcing principles and skills covered in lectures or in background reading. The target audience includes Field Epidemiology and Laboratory Training Programs (FELTPs), university students, district health executives, and health information officers.

Allogeneic chimeric antigen receptor-modified cells for adoptive cell therapy of cancer.

PubMed

Marcus, Assaf; Eshhar, Zelig

2014-07-01

Chimeric antigen (or antibody) receptors (CAR) are fusion proteins typically combining an antibody-derived targeting fragment with signaling domains capable of activating immune cells. Recent clinical trials have shown the tremendous potential of adoptive cell transfer (ACT) of autologous T cells engineered to express a CD19-specific CAR targeting B-cell malignancies. Building on this approach, ACT therapies employing allogeneic CAR-expressing cytotoxic cells are now being explored. The basic principles of CAR-ACT are introduced. The potential benefits as well as problems of using allogeneic CAR-modified cells against tumor antigens are discussed. Various approaches to allogeneic CAR therapy are presented, including donor leukocyte infusion, CAR-redirected γδ T cells and natural killer cells, strategies to avoid graft-versus-host disease, modulation of lymphocyte migration, and exploitation of graft-versus-host reactivity. CAR-modified allogeneic cells have the potential to act as universal effector cells, which can be administered to any patient regardless of MHC type. Such universal effector cells could be used as an 'off-the-shelf' cell-mediated treatment for cancer.

Magnetic particle hyperthermia—a promising tumour therapy?

NASA Astrophysics Data System (ADS)

Dutz, Silvio; Hergt, Rudolf

2014-11-01

We present a critical review of the state of the art of magnetic particle hyperthermia (MPH) as a minimal invasive tumour therapy. Magnetic principles of heating mechanisms are discussed with respect to the optimum choice of nanoparticle properties. In particular, the relation between superparamagnetic and ferrimagnetic single domain nanoparticles is clarified in order to choose the appropriate particle size distribution and the role of particle mobility for the relaxation path is discussed. Knowledge of the effect of particle properties for achieving high specific heating power provides necessary guidelines for development of nanoparticles tailored for tumour therapy. Nanoscale heat transfer processes are discussed with respect to the achievable temperature increase in cancer cells. The need to realize a well-controlled temperature distribution in tumour tissue represents the most serious problem of MPH, at present. Visionary concepts of particle administration, in particular by means of antibody targeting, are far from clinical practice, yet. On the basis of current knowledge of treating cancer by thermal damaging, this article elucidates possibilities, prospects, and challenges for establishment of MPH as a standard medical procedure.

2016-11-25

Gastrointestinal stromal tumor(GIST) is the most common mesenchymal tumor in the gastrointestinal tract. Due to the occult onset, GIST may present as local advanced or with metastatic disease at diagnosis. Imatinib mesylate (IM) has effectively improved the prognosis of GIST patients and has been established as principle therapy in metastatic GIST. The role of IM as an adjunction to surgery in the management of high-risk and local advanced GIST is also highly regarded. The role of surgery in metastatic or recurrent GIST is still a controversial clinic problem. For local advanced GIST or GIST in the unfavorable anatomic site(e.g. esophagogastric junction, duodenum, and rectum), based on the limited evidence, surgery may have potential benefits as conversion therapy. Surgery may have a limited favorable impact on progression-free survival and overall survival for those patients whose disease is responding to imatinib or those with limited focal progression. Patients with extensive advanced relapse metastatic GIST or imatinib-resistant disease should not undergo surgery unless emergency situation or complication occurs, where palliative intervention may be justified.

PubMed

Hantel-Quitmann, Wolfgang; Weidtmann, Katja

2016-01-01

The emotional family climate is considered both an effective risk and protective factor for child development. Factors such as negative experiences parents made during their childhood or adolescence, which can reoccur as intergenerational transmission, a low partnership quality and a high level of conflict seem to be particularly relevant for the quality of the emotional family climate. Consequently, the relationship between partners, as the core relation within families, is particularly important for the family climate and subsequently for the development of the child. For this reason, problems in parent relationships should receive special attention in family therapeutic interventions. Mentalisation-based family therapy (MBF-T) offers promising approaches in this context. The key principles of mentalisation are introduced and the links between family and mentalisation are presented, followed by information on the history, objectives and the procedures of MBF-T. A case study of a family therapy, in which a child suffers from chronic headache, illustrates the connection and interrelation between family climate, family conflicts and the parental relationship, and it will further show the importance of mentalisation-based elements for therapeutic treatments.

Treatment and prevention of music performance anxiety.

PubMed

Spahn, Claudia

2015-01-01

Music performance anxiety (MPA) regularly occurs when musicians present themselves before an audience in performance situations, and thus, it plays an important role in the careers of professional musicians. MPA is expressed on the emotional and physical level, as well as on the levels of thinking and behavior, and extends along a continuum of varying severity. Its performance-impairing, afflicting form is considered to be a specific type of social phobia, which requires therapy. There are different psychological theories, which contribute to the understanding of the phenomenon of MPA and provide basic principles for the various treatment approaches. Current "best practice," in our clinical experience, is a personal- and problem-oriented approach within a multimodal therapy model, including the range of psychoanalytic and cognitive behavioral therapies, body-oriented methods, and mental techniques. In order to avoid severe MPA, prevention in the field of music pedagogic is very important. Thus, the concepts of dealing positively with MPA should be implemented very early into the instrumental and vocal education of musicians. © 2015 Elsevier B.V. All rights reserved.

Facilitating Transfer of Skills and Strategies in Occupational Therapy Practice: Practical Application of Transfer Principles.

PubMed

Babulal, Ganesh M; Foster, Erin R; Wolf, Timothy J

2016-01-01

In Occupational Therapy (OT) practice, practitioners assume that the skills and strategies taught to clients during rehabilitation will transfer to performance and participation in everyday life. Despite transfer serving as a practice foundation, outcome studies conclude that this assumption of transfer is not occurring and it often results in decreased efficacy of rehabilitation. This paper investigated key aspects of transfer and found concepts in the psychology literature that can support transfer of skills and strategies in OT. Six key principles proposed from educational psychology can serve as a guide for practitioners to better train for transfer. In this paper, we discuss the six principles and apply concepts from psychology. Each principle is supported with examples of how they may be incorporated OT practice. If occupational therapists understand these principles and implement them in treatment, the efficacy of treatment may improve for many populations.

Documentation of the application of the principles of continuous quality improvement (CQI) to the health care setting is crucial for understanding the transition from traditional management models to CQI models. A CQI project was designed and implemented by the IV Therapy Department at Lawrence Memorial Hospital to test the application of these principles to intravenous therapy and as a learning tool for the entire organization. Through a prototype inventory project, significant savings in cost and time were demonstrated using check sheets, flow diagrams, control charts, and other statistical tools, as well as using the Plan-Do-Check-Act cycle. As a result, a primary goal, increased time for direct patient care, was achieved. Eight hours per week in nursing time was saved, relationships between two work areas were improved, and $6,000 in personnel costs, storage space, and inventory were saved.

Despite medical advances, heart failure (HF) remains a global health problem and sub-Saharan Africa (SSA) is no exception, with decompensated HF being the most common primary diagnosis for patients admitted to hospital with heart disease. In SSA the in-hospital mortality rate of decompensated HF is up to 8.3%. HF is a clinical syndrome that is caused by a diverse group of aetiologies, each requiring unique management strategies, highlighting the need for diagnostic certainty and a broad understanding of the complex pathophysiology of this condition. While there are a number of advanced medical, device and surgical interventions being tailored for HF internationally, the fundamental basic principles of HF management, such as patient education, effective management of congestion and initiation of disease-modifying medical therapies, remain a challenge on our continent. This review addresses both the epidemiology of HF in SSA and principles of management that focus specifically on symptom relief, prevention of hospitalisation and improving survival in this population.

Application of Transformational Leadership Principles in the Development and Integration of Palliative Care Within an Advanced Heart Failure Program.

Heart failure (HF) is a major health problem in United States, and it has reached epidemic proportions. Heart failure is associated with significant morbidity, mortality, and cost. Although the prognosis of HF is worse than many forms of cancer, many patients, families, and clinicians are unaware of the dire prognosis. As the disease progress to advanced HF, patients are faced with many challenges, such as poor quality of life due to worsening symptoms and frequent hospitalizations. Heart failure management adds significant financial burden to the health care system. Palliative care can be integrated into HF care to improve quality of life and symptom management and to address physical, spiritual, and psychosocial needs of patients and families. Palliative care can be used concurrently with or independent of curative or life-prolonging HF therapies. Transformational leadership principles were used to guide the development of a plan to enhance integration of palliative care within traditional advanced HF care.

The helper therapy principle (HTP) observes the helper’s health benefits derived from helping another with a shared malady. The HTP is embodied by the program of Alcoholics Anonymous as a method to diminish egocentrism as a root cause of addiction. This article reviews recent evidence of the HTP in alcohol populations, extends to populations with chronic conditions beyond addiction, and concludes with new directions of empirical inquiry.

Haddad, A M

1988-05-01

Ethical decision making is a cognitive skill requiring education in ethical principles and an understanding of specific ethical issues. It is also a psychodynamic process involving personalities, values, opinions, and perceptions. This article proposes the use of case studies and role-playing techniques in teaching ethics in occupational therapy to supplement conventional methods of presenting ethical theories and principles. These two approaches invite students to discuss and analyze crucial issues in occupational therapy from a variety of viewpoints. Methodology of developing case studies and role-playing exercises are discussed. The techniques are evaluated and their application to the teaching of ethics is examined.

Through the discussion on TCM physiological characters of females in follicular, ovulatory, luteal and menstrual phases and treatment principles, the clinical application of artificial cycle therapy of acupuncture and moxibustion was introduced for irregular menstruation and the typical cases were attached. It is suggested that the menstrual cycle follows the growth-consumption rule of yin, yang, qi and blood. The corresponding treatment principles should be applied in accordance with the change rule of menstrual cycle. Hence, it is worth to adopt the artificial cycle therapy of acupuncture and moxibustion for irregular menstruation in clinical application.

Anti–PD-1/PD-L1 therapy of human cancer: past, present, and future

PubMed Central

Chen, Lieping; Han, Xue

2015-01-01

Major progress has been made toward our understanding of the programmed death-1/programmed death ligand-1 (PD-1/PD-L1) pathway (referred to as the PD pathway). mAbs are already being used to block the PD pathway to treat human cancers (anti-PD therapy), especially advanced solid tumors. This therapy is based on principles that were discovered through basic research more than a decade ago, but the great potential of this pathway to treat a broad spectrum of advanced human cancers is just now becoming apparent. In this Review, we will briefly review the history and development of anti-PD therapy, from the original benchwork to the most up-to-date clinical results. We will then focus the discussion on three basic principles that define this unique therapeutic approach and highlight how anti-PD therapy is distinct from other immunotherapeutic approaches, namely tumor site immune modulation, targeting tumor-induced immune defects, and repairing ongoing (rather than generating de novo) tumor immunity. We believe that these fundamental principles set the standard for future immunotherapies and will guide our efforts to develop more efficacious and less toxic immune therapeutics to treat human cancers.

A novel conceptual framework for understanding the mechanism of adherence to long term therapies

PubMed Central

Reach, Gérard

2008-01-01

The World Health Organization claimed recently that improving patient adherence to long term therapies would be more beneficial than any biomedical progress. First, however, we must understand its mechanisms. In this paper I propose a novel approach using concepts elaborated in a field rarely explored in medicine, the philosophy of mind. While conventional psychological models (eg, the Health Belief Model) provide explanations and predictions which have only a statistical value, the philosophical assumption that mental states (eg, beliefs) are causally efficient (mental causation) can provide the basis for a causal theory of health behaviors. This paper shows that nonadherence to long term therapies can be described as the medical expression of a philosophical concept, that is, weakness of will. I use philosophical explanations of this concept to suggest a mechanistic explanation of nonadherence. I propose that it results from the failure of two principles of rationality. First, a principle of continence, described by the philosopher Donald Davidson in his explanation of weakness of will. This principle exhorts us to act after having considered all available arguments and according to which option we consider best. However, patients conforming to this principle of continence should rationally be nonadherent. Indeed, when patients face a choice between adherence and nonadherence, they must decide, in general, between a large, but delayed reward (eg, health) and a small, but immediate reward (eg, smoking a cigarette). According to concepts elaborated by George Ainslie and Jon Elster, the force of our desires is strongly influenced by the proximity of reward. This inter-temporal choice theory on one hand, and the mere principle of continence on the other, should therefore lead to nonadherence. Nevertheless, adherence to long term therapies is possible, as a result of the intervention of an additional principle, the principle of foresight, which tells us to give priority to mental states oriented towards the future.

[Exercise therapy in the treatment of idiopathic adolescent scoliosis: Is it useful?].

PubMed

Porte, M; Patte, K; Dupeyron, A; Cottalorda, J

2016-06-01

Many practitioners, pediatricians, and general practitioners prescribe physical therapy when tracking scoliosis. However, has physical therapy alone proved its efficacy in the care of the scoliosis to slow down progression? Our purpose is to report the results of a literature review on the effectiveness of rehabilitation in idiopathic scoliosis. No current study presents sufficient scientific proof to validate the efficacy of isolated exercise therapy in scoliosis. Learned societies recognize, however, the efficacy of combining conservative therapy (brace+physiotherapy) in idiopathic scoliosis. Should we then still prescribe rehabilitation without brace treatment? Although physical therapy alone does not seem effective in treating scoliosis, it can limit potential painful phenomena and be beneficial for respiratory function. The physical therapist can also teach the teenager the classic principles of hygiene of the back. It may therefore be appropriate to prescribe physical therapy, but the principles and objectives must be explained to the patient and family in light of current evidence-based medicine.

Two problems stand in the way of the author's embracing principlism: its individualistic bias and its capacity to block substantive ethical inquiry. The more serious problem the author finds to be its blocking function.

[A discussion of the curability of childhood epilepsies (author's transl)].

PubMed

Groh, C

1975-01-01

Permanent freedom from fits can be achieved in a large proportion of children with a history of epilepsy through precise individual adjustment and careful maintenance of the therapeutic regimen. A review of the cases treated at the Pediatric Clinic, out-Patient-Department for Epileptics, University of Vienna, reveals that at present about 70% of the patients have a good prognosis (the figures vary from 50 to 85%, depending on the seizure type). An important question which has received only scant attention in the literature arises in the case of patients who have remained free from epileptic fits over a period of many years, namely whether longterm antiepileptic therapy can be terminated and, if so, then when and how. Only very few studies deal specifically with this problem and even these do not provide entirely satisfactory answers to all the posed questions, not only with regard to the optimum time and mode of drug reduction, but also with regard to the principles underlying the choice of apparently suitable candidates for attempted termination of therapy. An attempt is made in this retrospective study comprising 375 patients who have been followed up over a period of at least 5 years, to throw some light on these problems. Indeed, results of statistical significance were obtained by the use of a new mathematical technique, which enables the formulation of new guiding principles in the resolution of all three above-mentioned questions. In consequence, it now appears within the power of the pediatrician to markedly reduce the risk of relapse, which in the case of childhood epilepsies, is about 20%, at present. In general, several basic principles must be adhered to. Total freedom from convulsions over an uninterrupted period of at least 3 years' duration is an absolute prerequisite for consideration of cessation of therapy. Reduction in antiepileptic drug dosage should be carried out as a stepwise procedure over a period of about 2 years. Regular clinical and EEG follow-up examinations should be performed over this period of drug reduction and for 5 years subsequently, in order to recognise and counteract promptly any early signs of possible relapse. The prerequisite convulsionfree period is raised to 4 to 5 years or even longer and the time over which therapy is tailed off increased accordingly in the presence of any of the following criteria: 1. "Endogenous" tendency to relapse, 2. persistence of paroxysmal EEG abnormalities or deterioration of the EEG during the attempt to reduce the dosage of antiepileptic drugs, 3. inveterate epilepsy. The cessation of fits and the termination of medication do not yet signify that all the after-effects of epilepsy are overcome. Social integration must also be achieved before this goal is reached. The psychopathological symptomatology of the patient plays an important role in determining the outcome, whereby the level of intelligence of the patient is the decisive factor...

A Sound Therapy-Based Intervention to Expand the Auditory Dynamic Range for Loudness among Persons with Sensorineural Hearing Losses: A Randomized Placebo-Controlled Clinical Trial.

The primary aim of this research was to evaluate the validity, efficacy, and generalization of principles underlying a sound therapy-based treatment for promoting expansion of the auditory dynamic range (DR) for loudness. The basic sound therapy principles, originally devised for treatment of hyperacusis among patients with tinnitus, were evaluated in this study in a target sample of unsuccessfully fit and/or problematic prospective hearing aid users with diminished DRs (owing to their elevated audiometric thresholds and reduced sound tolerance). Secondary aims included: (1) delineation of the treatment contributions from the counseling and sound therapy components to the full-treatment protocol and, in turn, the isolated treatment effects from each of these individual components to intervention success; and (2) characterization of the respective dynamics for full, partial, and control treatments. Thirty-six participants with bilateral sensorineural hearing losses and reduced DRs, which affected their actual or perceived ability to use hearing aids, were enrolled in and completed a placebo-controlled (for sound therapy) randomized clinical trial. The 2 × 2 factorial trial design was implemented with or without various assignments of counseling and sound therapy. Specifically, participants were assigned randomly to one of four treatment groups (nine participants per group), including: (1) group 1-full treatment achieved with scripted counseling plus sound therapy implemented with binaural sound generators; (2) group 2-partial treatment achieved with counseling and placebo sound generators (PSGs); (3) group 3-partial treatment achieved with binaural sound generators alone; and (4) group 4-a neutral control treatment implemented with the PSGs alone. Repeated measurements of categorical loudness judgments served as the primary outcome measure. The full-treatment categorical-loudness judgments for group 1, measured at treatment termination, were significantly greater than the corresponding pretreatment judgments measured at baseline at 500, 2,000, and 4,000 Hz. Moreover, increases in their "uncomfortably loud" judgments (∼12 dB over the range from 500 to 4,000 Hz) were superior to those measured for either of the partial-treatment groups 2 and 3 or for control group 4. Efficacy, assessed by treatment-related criterion increases ≥ 10 dB for judgments of uncomfortable loudness, was superior for full treatment (82% efficacy) compared with that for either of the partial treatments (25% and 40% for counseling combined with the placebo sound therapy and sound therapy alone, respectively) or for the control treatment (50%). The majority of the group 1 participants achieved their criterion improvements within 3 months of beginning treatment. The treatment effect from sound therapy was much greater than that for counseling, which was statistically indistinguishable in most of our analyses from the control treatment. The basic principles underlying the full-treatment protocol are valid and have general applicability for expanding the DR among individuals with sensorineural hearing losses, who may often report aided loudness problems. The positive full-treatment effects were superior to those achieved for either counseling or sound therapy in virtual or actual isolation, respectively; however, the delivery of both components in the full-treatment approach was essential for an optimum treatment outcome.

Crossing Borders: A Qualitative Study of How Occupational Therapy Educators and Scholars Develop and Sustain Global Partnerships.

2015-09-01

The World Federation of Occupational Therapists (WFOT) and the American Occupational Therapy Association promote a globally connected profession that responds to the needs of our diverse societies. Global partnerships are grounded on the principle that cross-cultural experiences are enriching and provide mutual benefits. The purpose of this study was to uncover how occupational therapy educators and scholars perceive and experience (1) developing and sustaining global partnerships and (2) lessons learned. In this qualitative study, 30 occupational therapy educators and researchers completed an online survey. Eight participated in an interview. Results found major themes that help develop and sustain partnerships: building relationship of trust and respect, communicating effectively, cultivating cultural competence, sharing power and resources with collaborators and creating a context for reciprocal learning. Lessons learned include a call to walking humbly, building relationships of trust and respect, establishing open and honest communication, supporting local solutions to local problems, ensuring equality of resources and learning from their global partners. The findings suggest that global partnerships have the potential to transform both partners if the partners engage with mutual understanding and respect. Limitations of this study include a small sample size and participant's pool limited to occupational therapists from United States. Recommendations for future research include qualitative studies to identify model occupational therapy programmes that sustain global partnerships using a diverse sample of international occupational therapy educators and researchers. © 2015 John Wiley & Sons, Ltd.

The immunotherapy of cancer has made significant strides in the past few years due to improved understanding of the underlying principles of tumor biology and immunology. These principles have been critical in the development of immunotherapy in the laboratory and in the implementation of immunotherapy in the clinic. This improved understanding of immunotherapy, enhanced by increased insights into the mechanism of tumor immune response and its evasion by tumors, now permits manipulation of this interaction and elucidates the therapeutic role of immunity in cancer. Also important, this improved understanding of immunotherapy and the mechanisms underlying immunity in cancer has fueled an expanding array of new therapeutic agents for a variety of cancers. Pegylated interferon-α2b as an adjuvant therapy and ipilimumab as therapy for advanced disease, both of which were approved by the United States Food and Drug Administration for melanoma in March 2011, are 2 prime examples of how an increased understanding of the principles of tumor biology and immunology have been translated successfully from the laboratory to the clinical setting. Principles that guide the development and application of immunotherapy include antibodies, cytokines, vaccines, and cellular therapies. The identification and further elucidation of the role of immunotherapy in different tumor types, and the development of strategies for combining immunotherapy with cytotoxic and molecularly targeted agents for future multimodal therapy for cancer will enable even greater progress and ultimately lead to improved outcomes for patients receiving cancer immunotherapy.

This article, the fifth in a series on dementia, discusses the principles of management and treatment of people with dementia. It describes how to proceed after a diagnosis of dementia has been made in the early stages of the condition, and general measures to maintain physical and mental health. Drug therapy for cognitive dysfunction is explained in the context of the National Institute for Health and Care Excellence guidance, and strategies for managing depression and psychotic symptoms are outlined. Non-pharmacological approaches are often effective. For behavioural problems such as agitation and aggression, it is important to try to understand any underlying factors. In general, the most important strategy is to avoid excessive prescribing.

1975-01-01

In part 1 of this paper, a minimum principle was found for the finite-state, finite-memory (FSFM) stochastic control problem. In part 2, conditions for the sufficiency of the minimum principle are stated in terms of the informational properties of the problem. This is accomplished by introducing the notion of a signaling strategy. Then a min-H algorithm based on the FSFM minimum principle is presented. This algorithm converges, after a finite number of steps, to a person - by - person extremal solution.

Using isomorphic problems to learn introductory physics

NASA Astrophysics Data System (ADS)

Lin, Shih-Yin; Singh, Chandralekha

2011-12-01

In this study, we examine introductory physics students’ ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred sixty-two students from a calculus-based and an algebra-based introductory physics course were given a quiz in the recitation in which they had to first learn from a solved problem provided and take advantage of what they learned from it to solve another problem (which we call the quiz problem) which was isomorphic. Previous research suggests that the multiple-concept quiz problem is challenging for introductory students. Students in different recitation classes received different interventions in order to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. We also conducted think-aloud interviews with four introductory students in order to understand in depth the difficulties they had and explore strategies to provide better scaffolding. We found that most students were able to learn from the solved problem to some extent with the scaffolding provided and invoke the relevant principles in the quiz problem. However, they were not necessarily able to apply the principles correctly. Research suggests that more scaffolding is needed to help students in applying these principles appropriately. We outline a few possible strategies for future investigation.

Evidence-based topical management of chronic wounds according to the T.I.M.E. principle.

2013-09-01

The number of patients suffering from chronic wound healing disorders in Germany alone is estimated to be 2.5-4 million. Therapy related expenses reach 5-8 billion Euros annually. This number is partially caused by costly dressing changes due to non-standardized approaches and the application of non-evidence-based topical wound therapies. The purpose of this paper is to elucidate a straightforward principle for the management of chronic wounds, and to review the available evidence for the particular therapy options. The T.I.M.E.-principle (Tissue management, Inflammation and infection control, Moisture balance, Epithelial [edge] advancement) was chosen as a systematic strategy for wound bed preparation. Literature was retrieved from the PubMed and Cochrane Library databases and subjected to selective analysis. Topical wound management should be carried out according to a standardized principle and should further be synchronized to the phases of wound healing. Despite the broad implementation of these products in clinical practice, often no benefit exists in the rate of healing, when evaluated in meta-analyses or systematic reviews. This insufficient evidence is additionally limited by varying study designs. In case of non-superiority, the results suggest to prefer relatively inexpensive wound dressings over expensive alternatives. Arbitrary endpoints to prove the effectiveness of wound dressings, contribute to the random use of such therapies. Defining rational endpoints for future studies as well as the deployment of structured therapy strategies will be essential for the economical and evidence-based management of chronic wounds. © The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

Principles of definitive soft tissue coverage with flaps.

2008-01-01

Despite the emergence of negative pressure wound therapy with reticulated open cell foam (NPWT/ROCF) as delivered by V.A.C.(R) Therapy (KCI, San Antonio, TX) for orthopaedic trauma, vascularized tissue transfer whether it be pedicle, free, or tissue transfer using the operating microscope or as an island, remains the mainstay of soft tissue reconstruction for orthopaedic traumatology. The critisism of microvascular procedures has been that they are lengthy, costly, and required technical expertise to perform. While technical skills are required, microsurgical care has evolved into a routine operation with high degrees of success in experienced hand. The problem that still remains is access to surgeons who are interested in soft tissue reconstruction and can perform definitive coverage with flaps. There is a need in the orthopaedic community to solve the problem of lack of flap surgeons and as a result, NPWT/ROCF has been touted as the answer to flap reconstruction. NPWT/ROCF is an important addition to soft tissue reconstruction but it serves as a bridge rather than definitive coverage in many hands. Just as wound technology is evolving with tissue substitutes, growth factors and NPWT/ROCF flaps technology continues to advance with new perforator flaps and local regional flaps, particularly the sural flap, coming on line as mainstays of soft tissue reconstruction.

PubMed

Oruba, Zuzanna; Chomyszyn-Gajewska, Maria

Photodynamic therapy (PDT) is based on the principle that the target cells are destroyed by means of toxic reactive oxygen species generated upon the interaction of a photosensitizer, light and oxygen. This method is nowadays widely applied in various branches of medicine, mainly in oncology and dermatology. It is also applied in dentistry in the treatment of oral potentially malignant disorders (like lichen planus or leukoplakia) and infectious conditions (periodontitis, herpetic cheilitis, root canal disinfection). The application of the photodynamic therapy in the abovementioned indications is worth attention, as the method is noninvasive, painless, and the results of the published studies seem promising. The present article aims at presenting the principle of the photodynamic therapy and, based on the literature, the possibilities and results of its application in dentistry.

Research suggests that agitation is a common symptom for hospice patients, but while studies have examined the outcomes of music therapy on the agitated behaviors of patients in other settings, none have addressed this symptom in patients with terminal illnesses. The study objective was to determine whether a single session of music therapy provided by a board certified music therapist and using the entrainment principle would decrease agitation in hospice patients. This pilot study was a single-blind, pretest/posttest design. Music therapists used the principle of entrainment with live music during the treatment session. Subjects included in the study were 77 patients at a large hospice in south Florida with documented agitation. Agitation was measured using the Overt Agitation Severity Scale (OASS) for 5 minutes prior to and 5 minutes following a 20 minute music therapy intervention. Results from 73 participants were analyzed with a mean difference of -5.77 points from pretest to posttest. Results indicating a decrease in agitation were statistically significant (p < 0.001) for the entire sample. Age, gender, location, and diagnosis were found to have no significant effects on the results. Results indicate that a single session of music therapy using the entrainment principle may be an effective treatment for hospice patients experiencing agitation.

The August Krogh principle applies to plants

Wayne, R.; Staves, M. P.

1996-01-01

The Krogh principle refers to the use of a large number of animals to study the large number of physiological problems, rather than limiting study to a particular organism for all problems. There may be organisms that are more suited to study of a particular problem than others. This same principle applies to plants. The authors are concerned with the recent trend in plant biology of using Arabidopsis thaliana as the "organism of choice." Arabidopsis is an excellent organism for molecular genetic research, but other plants are superior models for other research areas of plant biology. The authors present examples of the successful use of the Krogh principle in plant cell biology research, emphasizing the particular characteristics of the selected research organisms that make them the appropriate choice.

Radiation therapy is a major therapeutic modality in the management of cancer patients. Over 60% of these patients receive radiotherapy at some point during their course of treatment and over 90% will develop skin reactions after therapy. Problematic wound healing in radiation-damaged tissue constitutes a major surgical difficulty and despite all efforts, irradiated skin remains a therapeutic challenge. This review provides an overview of the fundamental principles of radiation therapy with regards to the wound healing in normal and irradiated skin. Furthermore, it presents techniques that describe how to prevent and manage skin side effects as well as prospects that may improve cutaneous wound repair in general and in irradiated skin.

Is evaluating complementary and alternative medicine equivalent to evaluating the absurd?

PubMed

Greasley, Pete

2010-06-01

Complementary and alternative therapies such as reflexology and acupuncture have been the subject of numerous evaluations, clinical trials, and systematic reviews, yet the empirical evidence in support of their efficacy remains equivocal. The empirical evaluation of a therapy would normally assume a plausible rationale regarding the mechanism of action. However, examination of the historical background and underlying principles for reflexology, iridology, acupuncture, auricular acupuncture, and some herbal medicines, reveals a rationale founded on the principle of analogical correspondences, which is a common basis for magical thinking and pseudoscientific beliefs such as astrology and chiromancy. Where this is the case, it is suggested that subjecting these therapies to empirical evaluation may be tantamount to evaluating the absurd.

Nursing essential principles: continuous renal replacement therapy.

Richardson, Annette; Whatmore, Jayne

2015-01-01

This article aims to guide critical care nurses with the care and management of patients on continuous renal replacement therapy (CRRT). CRRT, a highly specialized therapy involving complex nursing care, is used widely in the intensive care unit to treat patients with acute kidney injury. A literature search was conducted using CINAHL, Medline from PubMed and BNI using the search terms CRRT or continuous veno-venous haemofiltration and nursing or nurses from 2000 onwards and limited to the English language. The appraised evidence and expert opinion is used in this article. Four essential nursing principles for CRRT are reviewed (1) the importance of continuous assessment of the indications to influence the appropriate mode; (2) ensuring good vascular access; (3) the avoidance of unnecessary interruptions and (4) the prevention of complications. The identified four essential nursing principles provide guidance on this complex aspects of nursing practice. Specific nursing research to guide the care and management of this therapy is limited so should be explored in the future. Critical care nurses caring for and managing patients on CRRT require an understanding of how to deliver safe CRRT. © 2014 British Association of Critical Care Nurses.

Integrating video-feedback and cognitive preparation, social skills training and behavioural activation in a cognitive behavioural therapy in the treatment of childhood anxiety.

2014-01-01

The present study examined the effectiveness of a transdiagnostic prevention programme, Super Skills for Life (SSL), in children with anxiety problems. SSL is based on the principles of cognitive-behaviour therapy (CBT), behavioural activation, social skills training, and uses video-feedback and cognitive preparation as part of the treatment. Participants were 61 primary school children, aged 8-10 years, who were referred by their teachers as having significant anxiety problems. Children were video-recorded during a 2-min speech task in sessions 1 and 8, and during a social interaction task. All the children completed measures of anxiety symptoms, social skills, and self-esteem before and after participating in the 8-week SSL and at the 6-months follow-up assessment. Anxiety symptoms were significantly reduced at post-test and follow-up assessments. SSL also had a positive effect on hyperactivity, conduct, and peer problems although it took longer for these effects to occur. Behavioural indicators of anxiety during the 2-min speech task decreased, indicating that the independent raters observed behavioural change in the children from pre-treatment to follow-up. Boys had higher overall behavioural anxiety during the 2-min speech task at all three assessment periods, specifically showing higher lip contortions and leg movement than girls. The present study used an open clinical trial design, had small sample size, and did not use structured diagnostic interview schedules to assess anxiety disorders. This study provides preliminary empirical support for the effectiveness of SSL in children with anxiety problems. Copyright © 2014 Elsevier B.V. All rights reserved.

Bender, Michael T; Niederman, Michael S

2016-12-01

Community-acquired pneumonia (CAP) encompasses a broad spectrum of disease severity and may require outpatient, inpatient, or intensive care management. Successful treatment hinges on expedient delivery of appropriate antibiotic therapy tailored to both the likely offending pathogens and the severity of disease. This review summarizes key principles in starting treatment and provides recommended empiric therapy regimens for each site of care. In addition, we discuss the antimicrobial and anti-inflammatory role macrolides play in CAP, as well as specific information for managing individual CAP pathogens such as community-acquired methicillin-resistant Staphylococcus aureus and drug-resistant Streptococcus pneumoniae . We also examine several novel antibiotics being developed for CAP and review the evidence guiding duration of therapy and current best practices for the transition of hospitalized patients from intravenous antibiotics to oral therapy.

Noether's Theorem and its Inverse of Birkhoffian System in Event Space Based on Herglotz Variational Problem

NASA Astrophysics Data System (ADS)

Tian, X.; Zhang, Y.

2018-03-01

Herglotz variational principle, in which the functional is defined by a differential equation, generalizes the classical ones defining the functional by an integral. The principle gives a variational principle description of nonconservative systems even when the Lagrangian is independent of time. This paper focuses on studying the Noether's theorem and its inverse of a Birkhoffian system in event space based on the Herglotz variational problem. Firstly, according to the Herglotz variational principle of a Birkhoffian system, the principle of a Birkhoffian system in event space is established. Secondly, its parametric equations and two basic formulae for the variation of Pfaff-Herglotz action of a Birkhoffian system in event space are obtained. Furthermore, the definition and criteria of Noether symmetry of the Birkhoffian system in event space based on the Herglotz variational problem are given. Then, according to the relationship between the Noether symmetry and conserved quantity, the Noether's theorem is derived. Under classical conditions, Noether's theorem of a Birkhoffian system in event space based on the Herglotz variational problem reduces to the classical ones. In addition, Noether's inverse theorem of the Birkhoffian system in event space based on the Herglotz variational problem is also obtained. In the end of the paper, an example is given to illustrate the application of the results.

Denvir, Paul M; Cardone, Katie E; Parker, Wendy M; Cerulli, Jennifer

2018-02-01

Medication therapy management (MTM) is a comprehensive, patient-centered approach to improving medication use, reducing the risk of adverse events and improving medication adherence. Given the service delivery model and required outputs of MTM services, communication skills are of utmost importance. The objectives of this study were to identify and describe communication principles and instructional practices to enhance MTM training. Drawing on formative assessment data from interviews of both pharmacy educators and alumni, this article identifies and describes communication principles and instructional practices that pharmacy educators can use to enhance MTM training initiatives to develop student communication strategies. Analysis revealed five key communication challenges of MTM service delivery, two communication principles that pharmacy teachers and learners can use to address those challenges, and a range of specific strategies, derived from communication principles, that students can use when challenges emerge. Implications of the analysis for pharmacy educators and researchers are described. Proactive communication training provided during MTM advanced pharmacy practice experiences enabled students to apply the principles and instructional strategies to specific patient interactions during the advanced pharmacy practice experiences and in their post-graduation practice settings.

Balancing access to participation in research and protection from risks: applying the principle of justice.

PubMed

Kiskaddon, Sarah H

2005-04-01

The problem for Institutional Review Boards (IRBs) of balancing access to participation in research with protection of research subjects has always been a difficult one. IRBs, charged with applying the "Common Rule," as well as the Belmont Principles, in their review of clinical research, are given little guidance on approaching this problem. This article argues that the third Belmont Principle, the Justice Principle, may provide a useful framework for considering this balance. The changing research environment is discussed in an historical context, and the Justice Principle is considered both in the context of individual rights, as well as the potential benefit to classes of people. The author further suggests that application of the Justice Principle be driven by findings derived from an analysis of the first 2 principles. This feedback model will enable a more formal application of the Justice Principle and less ambiguous, more transparent, decisions regarding the equitable selection of subjects. The author calls for more systematic attention to the Justice Principle by IRBs, and proposes a model that includes incorporating the deliberation of the other Belmont Principles into the Justice Principle.

Problem solving therapy - use and effectiveness in general practice.

PubMed

Pierce, David

2012-09-01

Problem solving therapy (PST) is one of the focused psychological strategies supported by Medicare for use by appropriately trained general practitioners. This article reviews the evidence base for PST and its use in the general practice setting. Problem solving therapy involves patients learning or reactivating problem solving skills. These skills can then be applied to specific life problems associated with psychological and somatic symptoms. Problem solving therapy is suitable for use in general practice for patients experiencing common mental health conditions and has been shown to be as effective in the treatment of depression as antidepressants. Problem solving therapy involves a series of sequential stages. The clinician assists the patient to develop new empowering skills, and then supports them to work through the stages of therapy to determine and implement the solution selected by the patient. Many experienced GPs will identify their own existing problem solving skills. Learning about PST may involve refining and focusing these skills.

The national standard of "Regulations of Acupuncture-needle Manipulating Techniques" is one of the national Criteria of Acupuncturology for which a total of 22 items have been already established. In the process of formulation, a series of common and specific problems have been met. In the present paper, the authors expound these problems from 3 aspects, namely principles for formulation, methods for formulating criteria, and considerations about some problems. The formulating principles include selection and regulations of principles for technique classification and technique-related key factors. The main methods for formulating criteria are 1) taking the literature as the theoretical foundation, 2) taking the clinical practice as the supporting evidence, and 3) taking the expounded suggestions or conclusions through peer review.

Problem-Centered Supplemental Instruction in Biology: Influence on Content Recall, Content Understanding, and Problem Solving Ability

2017-08-01

To address the need for effective, efficient ways to apply active learning in undergraduate biology courses, in this paper, we propose a problem-centered approach that utilizes supplemental web-based instructional materials based on principles of active learning. We compared two supplementary web-based modules using active learning strategies: the first used Merrill's First Principles of Instruction as a framework for organizing multiple active learning strategies; the second used a traditional web-based approach. Results indicated that (a) the First Principles group gained significantly from pretest to posttest at the Remember level ( t(40) = -1.432, p = 0.08, ES = 0.4) and at the Problem Solving level ( U = 142.5, N1 = 21, N2 = 21, p = .02, ES = 0.7) and (b) the Traditional group gained significantly from pretest to posttest at the Remember level ( t(36) = 1.762, p = 0.043, ES = 0.6). Those in the First Principles group were significantly more likely than the traditional group to be confident in their ability to solve problems in the future (χ2 (2, N = 40) = 3.585, p = 0.09).

Physical Principle for Generation of Randomness

NASA Technical Reports Server (NTRS)

Zak, Michail

2009-01-01

A physical principle (more precisely, a principle that incorporates mathematical models used in physics) has been conceived as the basis of a method of generating randomness in Monte Carlo simulations. The principle eliminates the need for conventional random-number generators. The Monte Carlo simulation method is among the most powerful computational methods for solving high-dimensional problems in physics, chemistry, economics, and information processing. The Monte Carlo simulation method is especially effective for solving problems in which computational complexity increases exponentially with dimensionality. The main advantage of the Monte Carlo simulation method over other methods is that the demand on computational resources becomes independent of dimensionality. As augmented by the present principle, the Monte Carlo simulation method becomes an even more powerful computational method that is especially useful for solving problems associated with dynamics of fluids, planning, scheduling, and combinatorial optimization. The present principle is based on coupling of dynamical equations with the corresponding Liouville equation. The randomness is generated by non-Lipschitz instability of dynamics triggered and controlled by feedback from the Liouville equation. (In non-Lipschitz dynamics, the derivatives of solutions of the dynamical equations are not required to be bounded.)

A critique of principlism.

PubMed

Clouser, K D; Gert, B

1990-04-01

The authors use the term "principlism" to refer to the practice of using "principles" to replace both moral theory and particular moral rules and ideals in dealing with the moral problems that arise in medical practice. The authors argue that these "principles" do not function as claimed, and that their use is misleading both practically and theoretically. The "principles" are in fact not guides to action, but rather they are merely names for a collection of sometimes superficially related matters for consideration when dealing with a moral problem. The "principles" lack any systematic relationship to each other, and they often conflict with each other. These conflicts are unresolvable, since there is no unified moral theory from which they are all derived. For comparison the authors sketch the advantages of using a unified moral theory.

Split Orthogonal Group: A Guiding Principle for Sign-Problem-Free Fermionic Simulations

NASA Astrophysics Data System (ADS)

Wang, Lei; Liu, Ye-Hua; Iazzi, Mauro; Troyer, Matthias; Harcos, Gergely

2015-12-01

We present a guiding principle for designing fermionic Hamiltonians and quantum Monte Carlo (QMC) methods that are free from the infamous sign problem by exploiting the Lie groups and Lie algebras that appear naturally in the Monte Carlo weight of fermionic QMC simulations. Specifically, rigorous mathematical constraints on the determinants involving matrices that lie in the split orthogonal group provide a guideline for sign-free simulations of fermionic models on bipartite lattices. This guiding principle not only unifies the recent solutions of the sign problem based on the continuous-time quantum Monte Carlo methods and the Majorana representation, but also suggests new efficient algorithms to simulate physical systems that were previously prohibitive because of the sign problem.

Adaptable Constrained Genetic Programming: Extensions and Applications

NASA Technical Reports Server (NTRS)

Janikow, Cezary Z.

2005-01-01

An evolutionary algorithm applies evolution-based principles to problem solving. To solve a problem, the user defines the space of potential solutions, the representation space. Sample solutions are encoded in a chromosome-like structure. The algorithm maintains a population of such samples, which undergo simulated evolution by means of mutation, crossover, and survival of the fittest principles. Genetic Programming (GP) uses tree-like chromosomes, providing very rich representation suitable for many problems of interest. GP has been successfully applied to a number of practical problems such as learning Boolean functions and designing hardware circuits. To apply GP to a problem, the user needs to define the actual representation space, by defining the atomic functions and terminals labeling the actual trees. The sufficiency principle requires that the label set be sufficient to build the desired solution trees. The closure principle allows the labels to mix in any arity-consistent manner. To satisfy both principles, the user is often forced to provide a large label set, with ad hoc interpretations or penalties to deal with undesired local contexts. This unfortunately enlarges the actual representation space, and thus usually slows down the search. In the past few years, three different methodologies have been proposed to allow the user to alleviate the closure principle by providing means to define, and to process, constraints on mixing the labels in the trees. Last summer we proposed a new methodology to further alleviate the problem by discovering local heuristics for building quality solution trees. A pilot system was implemented last summer and tested throughout the year. This summer we have implemented a new revision, and produced a User's Manual so that the pilot system can be made available to other practitioners and researchers. We have also designed, and partly implemented, a larger system capable of dealing with much more powerful heuristics.

Theoretical and practical outline of the Copenhagen PACT narrative-based exercise counselling manual to promote physical activity in post-therapy cancer survivors.

PubMed

Midtgaard, Julie

2013-02-01

Sedentary behaviour and reduced exercise capacity are potential persisting effects of anti-cancer therapy that may predispose to serious health conditions. It is well-established that physical exercise may prevent some of these problems. However, the extent to which cancer survivors are able to adopt long-term physical activity habits depends largely on their motivation. This theoretical paper aims to outline how researchers and practitioners can draw from Antonovsky's salutogenetic theory and White & Epston's Narrative Therapy to develop and implement intervention efforts centered on promotion of long-term physical activity behaviour, while at the same time increasing the individual cancer survivor's sense of meaning and personal health resources. The Copenhagen PACT (Physical Activity after Cancer Treatment) Study targeting adoption and maintenance of regular physical activity in post-therapy cancer survivors is briefly presented including a brief review of the theoretical rationale behind the psychological component of the intervention, i.e. a narrative-based exercise counselling programme. Subsequently, particular attention is given to the core principles, different components and structure of the counselling manual including sample questions and examples of written documents that have emanated from the individual counselling sessions. The discussion includes consideration of some methodological challenges that arise when attempting to evaluate narrative-based interventions in the context of physical activity promotion in cancer rehabilitation and survivorship care.

Issues in the conduct of therapeutic trials in palliative care: an Australian perspective.

PubMed

Maddocks, Ian

2002-01-01

Palliative care has been slow to demonstrate that its common interventions are supported by high levels of evidence. There are multiple reasons for this--historical and cultural, as well as the recognised difficulties of conducting studies in dying persons. There are problems in isolating the effect of a single intervention from the many other changing dimensions which attend the progress of terminal illness, and problems also in defining particular outcomes free from the contaminating effect of other simultaneous changes in a patient's situation. Sickness is an interaction between disease and patient, and science sits more comfortably with the study of disease than with the understanding of the patient. Nevertheless, the therapies commonly employed for symptom management in individuals with advanced and terminal illness deserve more rigorous investigation to establish their efficacy. In Australia, new levels of government support for research have stimulated a closer examination of principles and practical guidelines for the conduct of research in this area of healthcare.

Management of Acute Isolated Soleal Vein Thrombosis in a Pregnant Patient With an Osteopathic Approach to Evaluation.

PubMed

Martingano, Daniel; Eisenberg, Justin; Aglialoro, George C

2016-01-01

In pregnant women, the risk of venous thromboembolism increases 4 to 5 fold over that in nonpregnant women. Deep vein thromboses in the calf occur in approximately 6% of cases, with a 20% incidence of propagation, but new imaging methods suggest a higher rate. Nevertheless, the management of isolated soleal vein thrombosis is currently one of the most debated issues in the field of venous thromboembolism, and a clear set of principles for the management of this unique clinical problem remains undefined. The authors present the case of a 37-year-old woman with a history of recurrent spontaneous abortions and cervical insufficiency who presented with a short cervix and acute right isolated soleal vein thrombosis. Long-term anticoagulantion therapy was recommended. Future studies on the risk of isolated soleal vein thrombosis propagation in the setting of pregnancy are required to identify the most effective treatment options for this clinical problem.

Assessing the Efficacy of Mobile Health Apps Using the Basic Principles of Cognitive Behavioral Therapy: Systematic Review.

PubMed

Rathbone, Amy Leigh; Clarry, Laura; Prescott, Julie

2017-11-28

Cognitive behavioral therapy (CBT) in its basic principle has developed itself as a stand-alone, substantial method of therapy. With effective application in therapy for a range of mental health issues, the spread of CBT methods to Web-based therapy sources is evident. The development of mobile phone apps using CBT principles is increasing within the research area. Despite the move to Web-based methods of therapy, it is argued that these methods lack the same efficacy of face-to-face therapy sessions. The aim of this review was to assess extent research findings with regard to the effectiveness of CBT-related mobile health (mHealth) apps. By assessing only studies employing a randomized controlled trial design, the review aimed to determine app efficacy within the highly regarded method of investigation. A comprehensive literature search was conducted across several databases. Search results were filtered, and results were subject to strict inclusion and exclusion criteria because of the nature of the review. Where possible, analysis of effect size was calculated and results reported. A total of 8 studies investigating the effectiveness of mHealth CBT-related apps across a range of mental health issues were reviewed. Three studies used the app against a control group, and 5 studies used the app intervention against another form of treatment or intervention. A range of effect sizes were seen across all included studies (d=-0.13 to 1.83; 0.03-1.44), with the largest effects often being seen when comparing the data from pre- to posttest for the app engaged group. The studies reviewed support the use of mHealth apps containing CBT principles for a range of mental health issues. However, the effectiveness over longer time periods should be assessed. Researchers and professionals should seek to collaborate effectively when creating new apps to enhance their effectiveness as a treatment for the general public. ©Amy Leigh Rathbone, Laura Clarry, Julie Prescott.

To measure agreement between advanced pharmacy practice experience students using a guided interview process and experienced clinical pharmacists using standard practices to identify drug therapy problems. Student pharmacists enrolled in an advanced pharmacy practice experience (APPE) and clinical pharmacists conducted medication therapy management interviews to identify drug therapy problems in elderly patients recruited from the community. Student pharmacists used a guided interview tool, while clinical pharmacists' interviews were conducted using their usual and customary practices. Student pharmacists also were surveyed to determine their perceptions of the interview tool. Fair to moderate agreement was observed on student and clinical pharmacists' identification of 4 of 7 drug therapy problems. Of those, agreement was significantly higher than chance for 3 drug therapy problems (adverse drug reaction, dosage too high, and needs additional drug therapy) and not significant for 1 (unnecessary drug therapy). Students strongly agreed that the interview tool was useful but agreed less strongly on recommending its use in practice. The guided interview process served as a useful teaching aid to assist student pharmacists to identify drug therapy problems.

Of those, agreement was significantly higher than chance for 3 drug therapy problems (adverse drug reaction, dosage too high, and needs additional drug therapy) and not significant for 1 (unnecessary drug therapy). Students strongly agreed that the interview tool was useful but agreed less strongly on recommending its use in practice. Conclusions The guided interview process served as a useful teaching aid to assist student pharmacists to identify drug therapy problems. PMID:21451770

Ecological principles, biodiversity, and the electric utility industry

NASA Astrophysics Data System (ADS)

Temple, Stanley A.

1996-11-01

The synthetic field of conservation biology uses principles derived from many different disciplines to address biodiversity issues. Many of these principles have come from ecology, and two simple ones that seem to relate to many issues involving the utility industry are: (1) “Everything is interconnected” (and should usually stay that way), and (2) “We can never do merely one thing.” The first principle can be applied to both the biotic and physical environments that are impacted by industrial activities. Habitat fragmentation and the loss of physical and biotic connectedness that results are frequently associated with transmission rights-of-way. These problems can be reduced—or even turned into conservation benefits—by careful planning and creative management. The second principle applies to the utility industry's programs to deal with carbon released by burning fossil fuels. Ecological knowledge can allow these programs to contribute to the preservation of biodiversity in addition to addressing a pollution problem. Without careful ecological analyses, industry could easily create new problems while implementing solutions to old ones.

AAMFT Master Series tapes: an analysis of the inclusion of feminist principles into family therapy practice.

PubMed

Haddock, S A; MacPhee, D; Zimmerman, T S

2001-10-01

Content analysis of 23 American Association for Marriage and Family Therapy Master Series tapes was used to determine how well feminist behaviors have been incorporated into "ideal" family therapy practice. Feminist behaviors were infrequent, being evident in fewer than 3% of time blocks in event sampling and 10 of 39 feminist behaviors of the Feminist Family Therapist Behavior Checklist. These eminent therapists most often dealt with empowerment of male clients and management of power differentials in the therapeutic relationship in a relatively feminist manner, but they tended to hold women responsible for family issues, endorsed traditional rather than egalitarian relationships, and overlooked how the social context affects families. Several of the therapists were blatantly sexist in their treatment of female clients, communicating disrespect of and pathologizing them. The few tapes portraying effective incorporation of feminist principles in family therapy indicate that a handful of behaviors are key to this approach.

Endoscopic Therapy in Crohn's Disease: Principle, Preparation, and Technique.

PubMed

Chen, Min; Shen, Bo

2015-09-01

Stricture and fistula are common complications of Crohn's disease. Endoscopic balloon dilation and needle-knife stricturotomy has become a valid treatment option for Crohn's disease-associated strictures. Endoscopic therapy is also increasingly used in Crohn's disease-associated fistula. Preprocedural preparations, including routine laboratory testing, imaging examination, anticoagulant management, bowel cleansing and proper sedation, are essential to ensure a successful and safe endoscopic therapy. Adverse events, such as perforation and excessive bleeding, may occur during endoscopic intervention. The endoscopist should be well trained, always be cautious, anticipate for possible procedure-associated complications, be prepared for damage control during endoscopy, and have surgical backup ready. In this review, we discuss the principle, preparation, techniques of endoscopic therapy, as well as the prevention and management of endoscopic procedure-associated complications. We propose that inflammatory bowel disease endoscopy may be a part of training for "super" gastroenterology fellows, i.e., those seeking a career in advanced endoscopy or in inflammatory bowel disease.

General principles of antimicrobial therapy.

Leekha, Surbhi; Terrell, Christine L; Edson, Randall S

2011-02-01

Antimicrobial agents are some of the most widely, and often injudiciously, used therapeutic drugs worldwide. Important considerations when prescribing antimicrobial therapy include obtaining an accurate diagnosis of infection; understanding the difference between empiric and definitive therapy; identifying opportunities to switch to narrow-spectrum, cost-effective oral agents for the shortest duration necessary; understanding drug characteristics that are peculiar to antimicrobial agents (such as pharmacodynamics and efficacy at the site of infection); accounting for host characteristics that influence antimicrobial activity; and in turn, recognizing the adverse effects of antimicrobial agents on the host. It is also important to understand the importance of antimicrobial stewardship, to know when to consult infectious disease specialists for guidance, and to be able to identify situations when antimicrobial therapy is not needed. By following these general principles, all practicing physicians should be able to use antimicrobial agents in a responsible manner that benefits both the individual patient and the community.

Helping parents deal with children's acute disciplinary problems without escalation: the principle of nonviolent resistance.

PubMed

Omer, H

2001-01-01

There are two kinds of escalation between parents and children with acute discipline problems: (a) complementary escalation, in which parental giving-in leads to a progressive increase in the child's demands, and (b) reciprocal escalation, in which hostility begets hostility. Extant programs for helping parents deal with children with such problems focus mainly on one kind of escalation to the neglect of the other. The systematic use of Gandhi's principle of "nonviolent resistance" allows for a parental attitude that counters both kinds of escalation. An intervention is described, which allows parents to put this principle into practice.

Disaster Management: Mental Health Perspective

PubMed Central

Math, Suresh Bada; Nirmala, Maria Christine; Moirangthem, Sydney; Kumar, Naveen C.

2015-01-01

Disaster mental health is based on the principles of ‘preventive medicine’ This principle has necessitated a paradigm shift from relief centered post-disaster management to a holistic, multi-dimensional integrated community approach of health promotion, disaster prevention, preparedness and mitigation. This has ignited the paradigm shift from curative to preventive aspects of disaster management. This can be understood on the basis of six ‘R’s such as Readiness (Preparedness), Response (Immediate action), Relief (Sustained rescue work), Rehabilitation (Long term remedial measures using community resources), Recovery (Returning to normalcy) and Resilience (Fostering). Prevalence of mental health problems in disaster affected population is found to be higher by two to three times than that of the general population. Along with the diagnosable mental disorders, affected community also harbours large number of sub-syndromal symptoms. Majority of the acute phase reactions and disorders are self-limiting, whereas long-term phase disorders require assistance from mental health professionals. Role of psychotropic medication is very limited in preventing mental health morbidity. The role of cognitive behaviour therapy (CBT) in mitigating the mental health morbidity appears to be promising. Role of Psychological First Aid (PFA) and debriefing is not well-established. Disaster management is a continuous and integrated cyclical process of planning, organising, coordinating and implementing measures to prevent and to manage disaster effectively. Thus, now it is time to integrate public health principles into disaster mental health. PMID:26664073

Theoretical implications of the neurotic paradox as a problem in behavior theory: An experimental resolution

PubMed Central

Stampfl, Thomas G.

1987-01-01

Why do human phobias last for months or years when such behavior should undergo extinction? This failure of extinction or persistence of self-defeating behavior of human disorders was labeled by Mowrer as the neurotic paradox. The paradox is cited by an ever-increasing number of critics who challenge any laboratory-based learning model of human psychopathology. Laboratory research, of course, omits essential requirements in the analysis of behavior, and the principles derived from such analyses must be combined in order to explain complex human behavaior. Validation for a behavioral model can thus be achieved if (a) basic principles inferred from observation of humans treated with a laboratory-derived extinction procedure (e.g., implosive therapy) are combined with (b) principles examined in laboratory research that are combined to generate unique predictions that correspond to known features of human phobic behavior. The latter evidence is briefly reviewed in research demonstrating sustained responding over one thousand consecutive active avoidance responses with complete avoidance of the “phobic” CS for an initial single shock trial. Differential reinforcement for responses to early sequential stimuli depends on minimal work requirement, and reinforcement by timeout from avoidance. This combination of factors effectively precludes extinction to main conditioned aversive stimuli for nonhumans, as it does for human phobias. Support for a laboratory model of human phobia is thereby attained. PMID:22477974

Manage Your Life Online (MYLO): a pilot trial of a conversational computer-based intervention for problem solving in a student sample.

PubMed

Gaffney, Hannah; Mansell, Warren; Edwards, Rachel; Wright, Jason

2014-11-01

Computerized self-help that has an interactive, conversational format holds several advantages, such as flexibility across presenting problems and ease of use. We designed a new program called MYLO that utilizes the principles of METHOD of Levels (MOL) therapy--based upon Perceptual Control Theory (PCT). We tested the efficacy of MYLO, tested whether the psychological change mechanisms described by PCT mediated its efficacy, and evaluated effects of client expectancy. Forty-eight student participants were randomly assigned to MYLO or a comparison program ELIZA. Participants discussed a problem they were currently experiencing with their assigned program and completed measures of distress, resolution and expectancy preintervention, postintervention and at 2-week follow-up. MYLO and ELIZA were associated with reductions in distress, depression, anxiety and stress. MYLO was considered more helpful and led to greater problem resolution. The psychological change processes predicted higher ratings of MYLO's helpfulness and reductions in distress. Positive expectancies towards computer-based problem solving correlated with MYLO's perceived helpfulness and greater problem resolution, and this was partly mediated by the psychological change processes identified. The findings provide provisional support for the acceptability of the MYLO program in a non-clinical sample although its efficacy as an innovative computer-based aid to problem solving remains unclear. Nevertheless, the findings provide tentative early support for the mechanisms of psychological change identified within PCT and highlight the importance of client expectations on predicting engagement in computer-based self-help.

Problem-solving therapy and supportive therapy in older adults with major depression and executive dysfunction.

The purpose of this study was to determine whether problem-solving therapy is an effective treatment in older patients with depression and executive dysfunction, a population likely to be resistant to antidepressant drugs. Participants were adults age 60 and older with major depression and executive dysfunction. Problem-solving therapy was modified to be accessible to this population. Participants were randomly assigned to 12 weekly sessions of problem-solving therapy or supportive therapy and assessed at weeks 3, 6, 9, and 12. Of the 653 individuals referred for this study, 221 met selection criteria and were enrolled in the study. Reduction of depressive symptom severity was comparable for the two treatment groups during the first 6 weeks of treatment, but at weeks 9 and 12 the problem-solving therapy group had a greater reduction in symptom severity, a greater response rate, and a greater remission rate than the supportive therapy group (response rates at week 9: 47.1% and 29.3%; at week 12:56.7% and 34.0%; remission rates at week 9: 37.9% and 21.7%; at week 12: 45.6% and 27.8%). Problem-solving therapy yielded one additional response or remission over supportive therapy for every 4.4-5.6 patients by the end of the trial. These results suggest that problem-solving therapy is effective in reducing depressive symptoms and leading to treatment response and remission in a considerable number of older patients with major depression and executive dysfunction. The clinical value of this finding is that problem-solving therapy may be a treatment alternative in an older patient population likely to be resistant to pharmacotherapy.

The harm principle as a mid-level principle?: three problems from the context of infectious disease control.

PubMed

Krom, André

2011-10-01

Effective infectious disease control may require states to restrict the liberty of individuals. Since preventing harm to others is almost universally accepted as a legitimate (prima facie) reason for restricting the liberty of individuals, it seems plausible to employ a mid-level harm principle in infectious disease control. Moral practices like infectious disease control support - or even require - a certain level of theory-modesty. However, employing a mid-level harm principle in infectious disease control faces at least three problems. First, it is unclear what we gain by attaining convergence on a specific formulation of the harm principle. Likely candidates for convergence, a harm principle aimed at preventing harmful conduct, supplemented by considerations of effectiveness and always choosing the least intrusive means still leave ample room for normative disagreement. Second, while mid-level principles are sometimes put forward in response to the problem of normative theories attaching different weight to moral principles, employing a mid-level harm principle completely leaves open how to determine what weight to attach to it in application. Third, there appears to be a trade-off between attaining convergence and finding a formulation of the harm principle that can justify liberty-restrictions in all situations of contagion, including interventions that are commonly allowed. These are not reasons to abandon mid-level theorizing altogether. But there is no reason to be too theory-modest in applied ethics. Morally justifying e.g. if a liberty-restriction in infectious disease control is proportional to the aim of harm-prevention, promptly requires moving beyond the mid-level harm principle. © 2011 Blackwell Publishing Ltd.

Changes in problem-solving appraisal after cognitive therapy for the prevention of suicide.

2012-06-01

Cognitive therapy has been found to be effective in decreasing the recurrence of suicide attempts. A theoretical aim of cognitive therapy is to improve problem-solving skills so that suicide no longer remains the only available option. This study examined the differential rate of change in problem-solving appraisal following suicide attempts among individuals who participated in a randomized controlled trial for the prevention of suicide. Changes in problem-solving appraisal from pre- to 6-months post-treatment in individuals with a recent suicide attempt, randomized to either cognitive therapy (n = 60) or a control condition (n = 60), were assessed by using the Social Problem-Solving Inventory-Revised, Short Form. Improvements in problem-solving appraisal were similarly observed for both groups within the 6-month follow-up. However, during this period, individuals assigned to the cognitive therapy condition demonstrated a significantly faster rate of improvement in negative problem orientation and impulsivity/carelessness. More specifically, individuals receiving cognitive therapy were significantly less likely to report a negative view toward life problems and impulsive/carelessness problem-solving style. Cognitive therapy for the prevention of suicide provides rapid changes within 6 months on negative problem orientation and impulsivity/carelessness problem-solving style. Given that individuals are at the greatest risk for suicide within 6 months of their last suicide attempt, the current study demonstrates that a brief cognitive intervention produces a rapid rate of improvement in two important domains of problem-solving appraisal during this sensitive period.

Derivation of Hamilton's equations of motion for mechanical systems with constraints on the basis of Pontriagin's maximum principle

Sylvia Docker lecture: the practice, research, policy nexus in contemporary occupational therapy.

Layton, Natasha A

2014-04-01

In this era of evidence-based practice, Australian occupational therapists largely accept scientific perspectives of the quality of evidence and 'what makes a strong study'. Yet unequal power relationships are usual between funders who set the research agenda, researchers and people who are the subjects of research. Emerging policy now mandates partnerships with consumers in any health and research projects about them. Are we person-centred in our research practices? What difference would increased consumer direction make to our research methods, scope and outcomes? This lecture describes some of the benefits and challenges of collaborative or inclusive research partnerships with consumers and outlines where this may take occupational therapy in future. The disability community's calls for inclusive research will be contrasted with mainstream research approaches and with occupational therapy's commitment to person-centredness. An example of inclusive research undertaken by the author and colleagues with disabilities which posed the question: 'What difference does assistive technology make to life for people living with impairment?' will be presented. Collaborative research is best conceptualised as a mutually productive journey, with many factors influencing how fully inclusive research principles can be realised. The possibilities and complexities of conducting research which has inclusive credentials are outlined. Inclusive research principles provide a means to enact person-centredness in research as well as practice. Following these principles challenges occupational therapy practitioners and researchers to address nexus issues: that is, intersections between and beyond research, policy and practice. © 2014 Occupational Therapy Australia.

Use of homeopathy in organic dairy farming in Spain.

Orjales, Inmaculada; López-Alonso, Marta; Rodríguez-Bermúdez, Ruth; Rey-Crespo, Francisco; Villar, Ana; Miranda, Marta

2016-02-01

Organic farming principles promote the use of unconventional therapies as an alternative to chemical substances (which are limited by organic regulations), with homeopathy being the most extensive. Traditionally, Spain has had little faith in homeopathy but its use in organic farming is growing. Fifty-six Spanish organic dairy farmers were interviewed to obtain what we believe to be the first data on the use of homeopathy in organic dairy cattle in Spain. Only 32% of farms use some sort of alternative therapy (16.1% homeopathy, 10.7% phytotherapy and 5.3% using both therapies) and interestingly, a clear geographical pattern showing a higher use towards the East (similar to that in the human population) was observed. The main motivation to use homeopathy was the need to reduce chemical substances promoted by organic regulations, and the treatment of clinical mastitis being the principle reason. The number of total treatments was lower in farms using homeopathy compared with those applying allopathic therapies (0.13 and 0.54 treatments/cow/year respectively) and although the bulk SCC was significantly higher (p < 0.001) in these farms (161,826 and 111,218 cel/ml, respectively) it did not have any negative economical penalty for the farmer and milk quality was not affected complying with the required standards; on the contrary homeopathic therapies seems to be an alternative for reducing antibiotic treatments, allowing farmers to meet the organic farming principles.

Abstract. Purpose behind developing these guidelines: Over one decade ago, the “Guidelines for the Treatment of Graves’ Disease with Antithyroid Drug, 2006” (Japan Thyroid Association (JTA)) were published as the standard drug therapy protocol for Graves’ disease. The “Guidelines for the Treatment of Childhood-Onset Graves’ Disease with Antithyroid Drug in Japan, 2008” were published to provide guidance on the treatment of pediatric patients. Based on new evidence, a revised version of the “Guidelines for the Treatment of Graves’ Disease with Antithyroid Drug, 2006” (JTA) was published in 2011, combined with the “Handbook of Radioiodine Therapy for Graves’ Disease 2007” (JTA). Subsequently, newer findings on pediatric Graves’ disease have been reported. Propylthiouracil (PTU)-induced serious hepatopathy is an important problem in pediatric patients. The American Thyroid Association’s guidelines suggest that, in principle, physicians must not administer PTU to children. On the other hand, the “Guidelines for the Treatment of Graves’ Disease with Antithyroid Drug, 2011” (JTA) state that radioiodine therapy is no longer considered a “fundamental contraindication” in children. Therefore, the “Guidelines for the Treatment of Childhood-Onset Graves’ Disease with Antithyroid Drug in Japan, 2008” required revision. PMID:28458457

Foundational principles of classical Ayurveda research

PubMed Central

Raha, Somik

2013-01-01

Double-blind randomized controlled trials (RCTs) are viewed as the golden standard of drug research in Western medicine. However, RCTs are far from “golden” in many respects. They are impractical for many therapies, such as for surgeries and complex lifestyle changes. They encourage a one-size-fits-all approach to medical treatment that fails to address the huge diversity among individual patients in terms of their physical and emotional symptoms, social and cultural upbringing, and other factors. Perhaps, more importantly, they do not help doctors make the best medical decisions required to produce optimal patient outcomes. To guide a search for an alternate model of medical research, three principles based on Ayurveda, an ancient and powerful system of health care that has stood the test of time, are presented. These principles, arrived at after mining Ayurvedic epistemology, are: Inductive learning, whole systems thinking, and individually optimized therapy. In honor of the ancient sages or “Rishis,” whose voice is used to deliver Ayurvedic knowledge in the ancient texts of Ayurveda, these are referred to as the “Rishi principles.” Common research methodologies are examined for embodiment of these principles.

Neuromodulation Therapies for Alcohol Addiction: A Literature Review.

PubMed

Azevedo, Celeste A; Mammis, Antonios

2018-02-01

The goal of this review is to explore alternative neurological therapies in the treatment of alcohol use disorder; including transcranial direct current stimulation (tDCS), transcranial magnetic stimulation, deep brain stimulation (DBS), electroconvulsive therapy (ECT), and the off-label use of the GABA B receptor agonist baclofen. A comprehensive literature search was conducted through EBSCOhost regarding the neurological therapies in the treatment of alcoholism discussed in this paper. To date, few studies have been conducted on the subject, sample sizes are consistently small, and long-term abstinence appears a common problem. tDCS has shown to temporarily reduce alcohol cravings but with a high number of long-term relapses, 50-70%. DBS and TMS, similarly, fail to overcome high relapse rates. In one DBS study, for example, only two of five patients achieved prolonged abstinence. ECT seems to avoid such problems, but only a single case study exists to date. As such, no solid conclusions can be made regarding its success in alcohol addiction treatment. Baclofen, however, implicated in studies with comparatively larger patient samples and higher efficacy rates, presents with great promise, particularly in patients with more severe forms of AUD. In one of the largest observational studies to date (100 subjects) 92% of patients reported craving suppression and long-term relapse rates were low. The side-effects of oral baclofen (i.e., somnolence, insomnia, dizziness, paresthesia, etc.) though, pose a principle limitation to its administration in alcohol addiction. Based on current information in the literature, the authors advocate that, following more extensive research on oral baclofen and its indications in the treatment of alcohol addiction, intrathecal administration be the next logical therapeutic option to be explored. In particular, those patients with severe AUD, requiring high doses of the medication, may benefit, as it eliminates the systemic side effects associated with oral baclofen. © 2017 International Neuromodulation Society.

Engineering death receptor ligands for cancer therapy.

Wajant, Harald; Gerspach, Jeannette; Pfizenmaier, Klaus

2013-05-28

CD95, TNFR1, TRAILR1 and TRAILR2 belong to a subgroup of TNF receptors which is characterized by a conserved cell death-inducing protein domain that connects these receptors to the apoptotic machinery of the cell. Activation of death receptors in malignant cells attracts increasing attention as a principle to fight cancer. Besides agonistic antibodies the major way to stimulate death receptors is the use of their naturally occurring "death ligands" CD95L, TNF and TRAIL. However, dependent from the concept followed to develop a death ligand-based therapy various limiting aspects have to be taken into consideration on the way to a "bedside" usable drug. Problems arise in particular from the cell associated transmembrane nature of the death ligands, the poor serum half life of the soluble fragments derived from the transmembrane ligands, the ubiquitous expression of the death receptors and the existence of additional non-death receptors of the death ligands. Here, we summarize strategies how these limitations can be overcome by genetic engineering. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Finite element analysis of time-independent superconductivity. Ph.D. Thesis Final Report

NASA Technical Reports Server (NTRS)

Schuler, James J.

1993-01-01

The development of electromagnetic (EM) finite elements based upon a generalized four-potential variational principle is presented. The use of the four-potential variational principle allows for downstream coupling of EM fields with the thermal, mechanical, and quantum effects exhibited by superconducting materials. The use of variational methods to model an EM system allows for a greater range of applications than just the superconducting problem. The four-potential variational principle can be used to solve a broader range of EM problems than any of the currently available formulations. It also reduces the number of independent variables from six to four while easily dealing with conductor/insulator interfaces. This methodology was applied to a range of EM field problems. Results from all these problems predict EM quantities exceptionally well and are consistent with the expected physical behavior.

Dynamics of Pure Shape, Relativity, and the Problem of Time

NASA Astrophysics Data System (ADS)

Barbour, Julian

A new approach to the dynamics of the universe based on work by Ó Murchadha, Foster, Anderson and the author is presented. The only kinematics presupposed is the spatial geometry needed to define configuration spaces in purely relational terms. A new formulation of the relativity principle based on Poincarés analysis of the problem of absolute and relative motion (Machs principle) is given. The entire dynamics is based on shape and nothing else. It leads to much stronger predictions than standard Newtonian theory. For the dynamics of Riemannian 3-geometries on which matter fields also evolve, implementation of the new relativity principle establishes unexpected links between special relativity, general relativity and the gauge principle. They all emerge together as a self-consistent complex from a unified and completely relational approach to dynamics. A connection between time and scale invariance is established. In particular, the representation of general relativity as evolution of the shape of space leads to a unique dynamical definition of simultaneity. This opens up the prospect of a solution of the problem of time in quantum gravity on the basis of a fundamental dynamical principle.

Ethics in reproductive genetics comprise descriptive ethics and normative ethics. Ethical problems before prenatal diagnosis involve genetic counseling and informed consent for the choice patients must make. Prenatal diagnosis using amniocentesis is controversial. An international survey of geneticists showed that 25% would do prenatal diagnosis for sex selection, and 17% would refer the couple elsewhere. Hungary (60%), India (37%), the US (34%), Canada (30%), Greece (29%), and Sweden (28%) would do prenatal diagnosis. The statistical incidence of positive findings after prenatal diagnosis does not exceed 4% of all cases when most couples choose abortion. Respect for parental choice and for nondirective counseling was supported in responses to 3 cases in the international survey that also had disclosure dilemmas included with abortion choices. 84% of respondents would be nondirective for XYY and 88% for XO. In India, Hungary, Turkey, and Norway, 46%, 40%, 40%, and 33%, respectively, would advise aborting an XO (Turner) fetus. A survey of 737 genetics and obstetricians and ethicists and clergy showed acceptability of abortion in singleton pregnancies and in twins associated strongly with the trimester of pregnancy, indication for selective termination, and fetal number. Prior group review of risks and benefits of experimental fetal therapy, case selection for experimental fetal therapy, the optimal informed-consent process for fetal therapy, twin pregnancies, refusal of proven fetal therapy, the lack of federal support for research in fetal diagnosis (preimplantation embryo diagnosis) and therapy, and sources of a moral obligation are also addressed. The Belmont Report on the ethics of biomedical research in the US proposed ethical principles to guide research with human subjects including the fetus: respect for parsons, beneficence, and justice.

The purpose of the study was to compare the effectiveness of massage based on the tensegrity principle and classical abdominal massage performed on patients with constipation. The study group consisted of 29 subjects with a pre-existing diagnosis of constipation based on the Rome III criteria. The patients were divided into two groups: the first group was made up of 15 patients who underwent tensegrity massage (average age: 59.8 years), and the second was made up of 14 patients who were given classical abdominal massage (average age: 55.7 years). The study consisted of six massage sessions in both groups, with two sessions per week performed over 21 days. The assessment was based on a patient questionnaire, the Rome III questionnaire and a diary of bowel movements. The results were analyzed before therapy, after one week of therapy and after the third (final) week of therapy. Changes in the number of defecations were compared between the two groups; the biggest changes occurred in the first and third week of therapy (P<0.01, calculated by the Mann-Whitey test). As a result of the therapy, tension during defecation dropped from 60% to 20% in Group I, and from 42.8% to 35.7% in Group II. The influence of the applied therapy was evaluated positively by 80% of the tensegrity massage group and 29% of the classical abdominal massage group. Massage based on the tensegrity principle may have a greater positive influence on the quality and quantity of bowel movements than classical abdominal massage. Copyright © 2015 Elsevier Ireland Ltd.

A closer look at opposing models for the T cell response to pathogens

NASA Astrophysics Data System (ADS)

Hanson, Shalla

2016-06-01

The problem of understanding the mechanisms of differentiation, activation, and interconversion of phenotypes of CD8+ T cells is one of crucial importance in cancer therapy, owing to both the anti-tumor efficacy of CD8+ T cells as well as the severe toxicity that results from excess expansion of this population. Several opposing theories exist which describe potential pathways for the development of the CD8+ T cell repertoire; however, the accuracy of each remains controversial. Here we review the current hypotheses, provide a critical overview of pivotal biological data from which these theories are derived, and discuss principle population-level implications. Finally, we offer a novel hypothesis which maintains consistency with each of the experimental studies and seeks to unify the currently opposing but not so disparate theories.

Evaluating the cost of therapy for restenosis: considerations for brachytherapy.

PubMed

Weintraub, W S

1996-11-01

Costs have become increasingly important in medicine in recent years as demand for services has outstripped readily available resources. Clinical microeconomics offers an approach to understanding cost and outcomes in an environment of economic scarcity. In this article the types of costs and methods for determining cost are presented. In addition, methods for assessing outcome and outcome in relation to cost are developed. Restenosis after coronary angioplasty is a prime example of a clinical problem requiring economic evaluation. This is because it results in little serious morbidity except for recurrent chest pain, but it has serious economic consequences which occur some time after the original angioplasty. This makes the economic assessment of restenosis complicated. The application of health care microeconomic principles to brachytherapy for restenosis in the coronary arteries is presented.

The application of constructivism to concepts of occupation using a group process approach.

Lederer, J M

2001-01-01

Students in an undergraduate occupational therapy program used the concepts of constructivism and the group process to select and decoupage chairs depicting varieties of occupations for one of four life span segments: infancy, adolescence, young adulthood and older adulthood. Students were not provided a set of specific guidelines to follow during the process but constructed their learning according to their creativity and hands-on application of classroom concepts. Student feedback indicated that, while they found the experience challenging, they enjoyed the process and learned a great deal not only about the group process but also about how to approach and solve unfamiliar problems. Results suggest the similarity between principles underlying good education and those underlying occupational performance. Implications for classroom instruction are discussed.

Ortiz-Frágola, Alfredo

2017-05-01

The author analyzes certain aspects of the psychopathology of addictions in adolescence, from a psychoanalytical and neurobiological point of view. Within the feld of present psychopathology we frequently fnd problems related with use and abuse of substances, particularly in adolescent therapy. Impulsivity, violence, marginalization, and primitive phantasies appear in the setting along with the functioning of the "addictive brain". Several aspects of vulnerability in adolescence, like depressive symptoms or narcissistic unbalance are connected with two basic principles in addiction: 1) drugs as a mean of obtaining pleasure, and 2) drugs as self regulators. The paper also describes the brain reward systems and the effect of drugs as neurotransmitters within the framework of intersubjectivity. A social approach completes the interdisciplinary work and enables us to use different explanatory models.

Management of "dual diagnosis" patients : consensus, controversies and considerations.

Basu, D; Gupta, N

2000-01-01

The term 'dual diagnosis' denotes the coexistence of substance use disorder(s) and other, non-substance-use, psychiatric disorder(s). The last two decades, and especially the 1990s, have witnessed tremendous research and clinical interest in this previously neglected area. India, however, lags behind, inspite of indications that the problem exists here too. The current approach to managing such patients is the 'integrated treatment model' in which the same clinician (or team of clinicians) provides treatment for both the disorders at the same time, treating both with equal understanding and importance. Both pharmacotherapy as well as psychosocial therapies are specifically designed keeping in mind the 'integrated' philosophy of treatment. The specific principles and components are described Areas of difficulty, uncertainty, and future considerations are highlighted, with a note on the Indian setting.

Analysis of superconducting electromagnetic finite elements based on a magnetic vector potential variational principle

NASA Technical Reports Server (NTRS)

Schuler, James J.; Felippa, Carlos A.

1991-01-01

Electromagnetic finite elements are extended based on a variational principle that uses the electromagnetic four potential as primary variable. The variational principle is extended to include the ability to predict a nonlinear current distribution within a conductor. The extension of this theory is first done on a normal conductor and tested on two different problems. In both problems, the geometry remains the same, but the material properties are different. The geometry is that of a 1-D infinite wire. The first problem is merely a linear control case used to validate the new theory. The second problem is made up of linear conductors with varying conductivities. Both problems perform well and predict current densities that are accurate to within a few ten thousandths of a percent of the exact values. The fourth potential is then removed, leaving only the magnetic vector potential, and the variational principle is further extended to predict magnetic potentials, magnetic fields, the number of charge carriers, and the current densities within a superconductor. The new element produces good results for the mean magnetic field, the vector potential, and the number of superconducting charge carriers despite a relatively high system condition number. The element did not perform well in predicting the current density. Numerical problems inherent to this formulation are explored and possible remedies to produce better current predicting finite elements are presented.

The genetic difference principle.

PubMed

Farrelly, Colin

2004-01-01

In the newly emerging debates about genetics and justice three distinct principles have begun to emerge concerning what the distributive aim of genetic interventions should be. These principles are: genetic equality, a genetic decent minimum, and the genetic difference principle. In this paper, I examine the rationale of each of these principles and argue that genetic equality and a genetic decent minimum are ill-equipped to tackle what I call the currency problem and the problem of weight. The genetic difference principle is the most promising of the three principles and I develop this principle so that it takes seriously the concerns of just health care and distributive justice in general. Given the strains on public funds for other important social programmes, the costs of pursuing genetic interventions and the nature of genetic interventions, I conclude that a more lax interpretation of the genetic difference principle is appropriate. This interpretation stipulates that genetic inequalities should be arranged so that they are to the greatest reasonable benefit of the least advantaged. Such a proposal is consistent with prioritarianism and provides some practical guidance for non-ideal societies--that is, societies that do not have the endless amount of resources needed to satisfy every requirement of justice.

Principles for Framing a Healthy Food System.

Hamm, Michael W

2009-07-01

Wicked problems are most simply defined as ones that are impossible to solve. In other words, the range of complex interacting influences and effects; the influence of human values in all their range; and the constantly changing conditions in which the problem exists guarantee that what we strive to do is improve the situation rather than solve the wicked problem. This does not mean that we cannot move a long way toward resolving the problem but simply that there is no clean endpoint. This commentary outlines principles that could be used in moving us toward a healthy food system within the framework of it presenting as a wicked problem.

Maximum principle for a stochastic delayed system involving terminal state constraints.

Wen, Jiaqiang; Shi, Yufeng

2017-01-01

We investigate a stochastic optimal control problem where the controlled system is depicted as a stochastic differential delayed equation; however, at the terminal time, the state is constrained in a convex set. We firstly introduce an equivalent backward delayed system depicted as a time-delayed backward stochastic differential equation. Then a stochastic maximum principle is obtained by virtue of Ekeland's variational principle. Finally, applications to a state constrained stochastic delayed linear-quadratic control model and a production-consumption choice problem are studied to illustrate the main obtained result.

The efficacy of problem solving therapy to reduce post stroke emotional distress in younger (18-65) stroke survivors.

2017-11-26

To investigate the efficacy of problem solving therapy for reducing the emotional distress experienced by younger stroke survivors. A non-randomized waitlist controlled design was used to compare outcome measures for the treatment group and a waitlist control group at baseline and post-waitlist/post-therapy. After the waitlist group received problem solving therapy an analysis was completed on the pooled outcome measures at baseline, post-treatment, and three-month follow-up. Changes on outcome measures between baseline and post-treatment (n = 13) were not significantly different between the two groups, treatment (n = 13), and the waitlist control group (n = 16) (between-subject design). The pooled data (n = 28) indicated that receiving problem solving therapy significantly reduced participants levels of depression and anxiety and increased quality of life levels from baseline to follow up (within-subject design), however, methodological limitations, such as the lack of a control group reduce the validity of this finding. The between-subject results suggest that there was no significant difference between those that received problem solving therapy and a waitlist control group between baseline and post-waitlist/post-therapy. The within-subject design suggests that problem solving therapy may be beneficial for younger stroke survivors when they are given some time to learn and implement the skills into their day to day life. However, additional research with a control group is required to investigate this further. This study provides limited evidence for the provision of support groups for younger stroke survivors post stroke, however, it remains unclear about what type of support this should be. Implications for Rehabilitation Problem solving therapy is no more effective for reducing post stroke distress than a wait-list control group. Problem solving therapy may be perceived as helpful and enjoyable by younger stroke survivors. Younger stroke survivors may use the skills learnt from problem solving therapy to solve problems in their day to day lives. Younger stroke survivors may benefit from age appropriate psychological support; however, future research is needed to determine what type of support this should be.

A finite state, finite memory minimum principle, part 2. [a discussion of game theory, signaling, stochastic processes, and control theory

NASA Technical Reports Server (NTRS)

Sandell, N. R., Jr.; Athans, M.

1975-01-01

The development of the theory of the finite - state, finite - memory (FSFM) stochastic control problem is discussed. The sufficiency of the FSFM minimum principle (which is in general only a necessary condition) was investigated. By introducing the notion of a signaling strategy as defined in the literature on games, conditions under which the FSFM minimum principle is sufficient were determined. This result explicitly interconnects the information structure of the FSFM problem with its optimality conditions. The min-H algorithm for the FSFM problem was studied. It is demonstrated that a version of the algorithm always converges to a particular type of local minimum termed a person - by - person extremal.

A collaborative learning approach for service-oriented introductory physics

NASA Astrophysics Data System (ADS)

Smith, Michael R.

1997-03-01

I have taught algebra-based introductory physics for six years to liberal arts students. It was primarily a service course for students majoring in Athletic Training, Physical Therapy, Geology, Biology, and Pre-Med. The typical student was characterized by having a minimal math and problem-solving proficiency. There also was a pattern of students being predisposed to memorizing facts and formulas, and attempting to solve problems by finding the correct formula and "plugging in" numbers to get an answer. The students seemed to have a minimal ability in deductive reasoning and problem solving, starting from basic principles. It is no wonder that they entered the introductory physics service course with extreme trepidation, based upon a strongly perceived physics phobia. A standard lecture format was used for the class size of approximately 25-30 students; and an attempt was always made to engage the students through the Socratic approach, by asking leading questions during the course of the lecture. The students were relatively unprepared and couldn't participate in the class, and often responded antagonistically. They indicated they didn't want to be asked to think about an issue, but would rather just be told the facts so they could take specific notes for subsequent memorization. It was clear from the results of the open book exams given during the semester that the majority of students could not approach problem solving using deductive reasoning based on basic principles, but relied on attempting to force-fit the problem into a worked example in the text (often out of context, with illogical results). The absentee rate in the classroom was usually around 30-40%. The academic administration of my liberal arts university has the policy of formal course evaluations by the students at the end of each semester. The evaluation questionnaire appears to be primarily a measurement of the stress level of the student during the course, and the evaluation score I received for the service physics course was typically on the order of 3 out of a possible 5; a score considered unsatisfactory by the administration.

United We Stand: Emphasizing Commonalities Across Cognitive-Behavioral Therapies

Mennin, Douglas S.; Ellard, Kristen K.; Fresco, David M.; Gross, James J.

2016-01-01

Cognitive behavioral therapy (CBT) has a rich history of alleviating the suffering associated with mental disorders. Recently, there have been exciting new developments, including multi-component approaches, incorporated alternative therapies (e.g., meditation), targeted and cost-effective technologies, and integrated biological and behavioral frameworks. These field-wide changes have led some to emphasize the differences among variants of CBT. Here, we draw attention to commonalities across cognitive-behavioral therapies, including shared goals, change principles, and therapeutic processes. Specifically, we offer a framework for examining common CBT characteristics that emphasizes behavioral adaptation as a unifying goal and three core change principles, namely (1) context engagement to promote adaptive imagining and enacting of new experiences; (2) attention change to promote adaptive sustaining, shifting, and broadening of attention; and (3) cognitive change to promote adaptive perspective taking on events so as to alter verbal meanings. Further, we argue that specific intervention components including behavioral exposure/activation, attention training, acceptance/tolerance, decentering/defusion, and cognitive reframing may be emphasized to a greater or lesser degree by different treatment packages but are still fundamentally common therapeutic processes that are present across approaches and are best understood by their relationships to these core CBT change principles. We conclude by arguing for shared methodological and design frameworks for investigating unique and common characteristics to advance a unified and strong voice for CBT in a widening, increasingly multimodal and interdisciplinary, intervention science.

Continuous Dual Resetting of the Immune Repertoire as a Basic Principle of the Immune System Function.

PubMed

Balzar, Silvana

2017-01-01

Idiopathic chronic inflammatory conditions (ICIC) such as allergy, asthma, chronic obstructive pulmonary disease, and various autoimmune conditions are a worldwide health problem. Understanding the pathogenesis of ICIC is essential for their successful therapy and prevention. However, efforts are hindered by the lack of comprehensive understanding of the human immune system function. In line with those efforts, described here is a concept of stochastic continuous dual resetting (CDR) of the immune repertoire as a basic principle that governs the function of immunity. The CDR functions as a consequence of system's thermodynamically determined intrinsic tendency to acquire new states of inner equilibrium and equilibrium against the environment. Consequently, immune repertoire undergoes continuous dual (two-way) resetting: against the physiologic continuous changes of self and against the continuously changing environment. The CDR-based dynamic concept of immunity describes mechanisms of self-regulation, tolerance, and immunosenescence, and emphasizes the significance of immune system's compartmentalization in the pathogenesis of ICIC. The CDR concept's relative simplicity and concomitantly documented congruency with empirical, clinical, and experimental data suggest it may represent a plausible theoretical framework to better understand the human immune system function.

Spontaneous evolution of microstructure in materials

NASA Astrophysics Data System (ADS)

Kirkaldy, J. S.

1993-08-01

Microstructures which evolve spontaneously from random solutions in near isolation often exhibit patterns of remarkable symmetry which can only in part be explained by boundary and crystallographic effects. With reference to the detailed experimental record, we seek the source of causality in this natural tendency to constructive autonomy, usually designated as a principle of pattern or wavenumber selection in a free boundary problem. The phase field approach which incorporates detailed boundary structure and global rate equations has enjoyed some currency in removing internal degrees of freedom, and this will be examined critically in reference to the migration of phase-antiphase boundaries produced in an order-disorder transformation. Analogous problems for singular interfaces including solute trapping are explored. The microscopic solvability hypothesis has received much attention, particularly in relation to dendrite morphology and the Saffman-Taylor fingering problem in hydrodynamics. A weak form of this will be illustrated in relation to local equilibrium binary solidification cells which renders the free boundary problem unique. However, the main thrust of this article concerns dynamic configurations at anisotropic singular interfaces and the related patterns of eutectoid(ic)s, nonequilibrium cells, cellular dendrites, and Liesegang figures where there is a recognizable macroscopic phase space of pattern fluctuations and/or solitons. These possess a weakly defective stability point and thereby submit to a statistical principle of maximum path probability and to a variety of corollary dissipation principles in the determination of a unique average patterning behavior. A theoretical development of the principle based on Hamilton's principle for frictional systems is presented in an Appendix. Elements of the principles of scaling, universality, and deterministic chaos are illustrated.

Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

Quantum correlations are tightly bound by the exclusivity principle.

PubMed

Yan, Bin

2013-06-28

It is a fundamental problem in physics of what principle limits the correlations as predicted by our current description of nature, based on quantum mechanics. One possible explanation is the "global exclusivity" principle recently discussed in Phys. Rev. Lett. 110, 060402 (2013). In this work we show that this principle actually has a much stronger restriction on the probability distribution. We provide a tight constraint inequality imposed by this principle and prove that this principle singles out quantum correlations in scenarios represented by any graph. Our result implies that the exclusivity principle might be one of the fundamental principles of nature.

Lingering Problems of Currency and Scope in Daniels's Argument for a Societal Obligation to Meet Health Needs

PubMed Central

Sachs, Benjamin

2010-01-01

Norman Daniels's new book, Just Health, brings together his decades of work on the problem of justice and health. It improves on earlier writings by discussing how we can meet health needs fairly when we cannot meet them all and by attending to the implications of the socioeconomic determinants of health. In this article I return to the core idea around which the entire theory is built: that the principle of equality of opportunity grounds a societal obligation to meet health needs. I point, first, that nowhere does Daniels say just what version of that principle he accepts. I then proceed to construct a principle on his behalf, based on a faithful reading of Just Health. Once we actually nail down the principle, I argue, we will find that there are two problems: it is implausible in itself, and it fails to ground a societal obligation to meet health needs.

Defending the beauty of the Invariance Principle

NASA Astrophysics Data System (ADS)

Barkana, Itzhak

2014-01-01

Customary stability analysis methods for nonlinear nonautonomous systems seem to require a strict condition of uniform continuity. Although extensions of LaSalle's Invariance Principle to nonautonomous systems that mitigate this condition have been available for a long time, they have remained surprisingly unknown or open to misinterpretations. The large scope of the Principle might have misled the prospective users and its application to Control problems has been received with amazing yet clear uneasiness. Counterexamples have been used in order to claim that the Invariance Principle cannot be applied to nonlinear nonautonomous systems. Because the original formulation of the Invariance Principle still imposes conditions that are not necessarily needed, this paper presents a new Invariance Principle that further mitigates previous conditions and thus further expands the scope of stability analysis. A brief comparative review of various alternatives to stability analysis of nonautonomous nonlinear systems and their implications is also presented in order to illustrate that thorough analysis of same examples may actually confirm the efficiency of the Invariance Principle approach when dealing with stability of nonautonomous nonlinear systems problems that may look difficult or even unsolvable otherwise.

A Qualitative Exploration of the Use of Attachment Theory in Adult Psychological Therapy.

Burke, Eilish; Danquah, Adam; Berry, Katherine

2016-01-01

There is a growing interest into how attachment theory can inform psychotherapeutic practice with adults. This study aimed to explore how a group of therapists with an interest in attachment theory use it in their work with adult clients. A cross-sectional qualitative design was adopted. Sampling, data collection and analysis procedures were guided by grounded theory principles. Semi-structured telephone interviews were conducted with 12 therapists from a variety of training backgrounds. Data were coded and developed into thematic categories. Six primary themes were identified to describe how attachment theory influenced the clinical practice of the sample through the following: (i) complementing other therapeutic models; (ii) providing a framework to understand the development of clients' mental health problems; (iii) working with different attachment styles; (iv) thinking about the therapeutic relationship as an attachment relationship; (iv) influencing the different stages of the therapeutic process; and (vi) influencing clinical service design and delivery. It is concluded that attachment theory can play a significant role in influencing the practice of therapists and can be usefully adopted to complement therapeutic processes irrespective of the therapist's dominant clinical orientation. Further research is needed to explore the views of clinicians from different theoretical orientations and to investigate the security of the client-therapist attachment within the context of therapeutic change processes. Attachment theory may have implications for practice across a range of different types of therapy and may help therapists to bridge apparent differences between modality-specific formulation and techniques. Attachment theory can be used to understand the development of mental health problems. Therapists should assess and formulate clients' attachment styles, and these formulations should guide therapeutic approaches. Attachment theory provides a comprehensive framework for facilitating the therapist's attentiveness to relational issues and use of the therapeutic relationship as a fulcrum for change. The principles of attachment theory can be used to inform all stages of the therapeutic process, as well as the design and delivery of mental health services.

Kehlet, H

2009-08-01

Recent evidence has documented that a combination of single-modality evidence-based care principles into a multimodal effort to enhance postoperative recovery (the fast track methodology) has led to enhanced recovery with reduced medical morbidity, need for hospitalisation and convalescence. Nevertheless, general implementation of fast track surgery has been relatively slow despite concomitant economic benefits. Further improvement in postoperative outcome may be obtained by developments within each care principle with a specific focus on minimally invasive surgery, effective multimodal, non-opioid analgesia and pharmacological stress reduction.

Antibiotics were unnecessarily prescribed in 45 cases of acute irreversible pulpitis, 10 chronic apical abscess, 6 acute apical paradontitis, 7 gingivitis, 10 periodontitis, 4 epulis, 2 TMJ (temporomandibular junction) dysfunction, 2 sharp ridge of alveolar bone, 1 burning mouth syndrome and 1 recurrent aphthous stomatitis. In 108 (53.2 per cent) of the cases, the prescribed antibiotics were found to be penicillins, 102 of which were broad-spectrum. It was also determined that only 6 (7.7 per cent) of the 78 cases diagnosed as acute apical abscess were given drainage as local therapy. Principles for treating dental infections suggest that an antibiotic should only be used to supplement and not substitute for conventional surgical methods. Therefore, in cases with acute apical abscess, mechanical treatment (drainage) should be the first step. Inappropriate antibiotic use is quite widespread in dentistry. Dentists should avoid inappropriate use of antibiotics. To prevent inappropriate administration, necessary precautions need to be taken against dispensing antibiotics without prescription.

This Contractor Report (CR) is a compilation of Lessons Learned in approximately 55 years of engineering experience by each James C. Blair, Robert S. Ryan, and Luke A. Schutzenhofer. The lessons are the basis of a course on Lessons Learned that has been taught at Marshall Space Flight Center. The lessons are drawn from NASA space projects and are characterized in terms of generic lessons learned from the project experience, which are further distilled into overarching principles that can be applied to future projects. Included are discussions of the overarching principles followed by a listing of the lessons associated with that principle. The lesson with sub-lessons are stated along with a listing of the project problems the lesson is drawn from, then each problem is illustrated and discussed, with conclusions drawn in terms of Lessons Learned. The purpose of this CR is to provide principles learned from past aerospace experience to help achieve greater success in future programs, and identify application of these principles to space systems design. The problems experienced provide insight into the engineering process and are examples of the subtleties one experiences performing engineering design, manufacturing, and operations. The supplemental CD contains accompanying PowerPoint presentations.

Advances in first-principles calculations of thermodynamic properties of planetary materials (Invited)

NASA Astrophysics Data System (ADS)

Wilson, H. F.

2013-12-01

First-principles atomistic simulation is a vital tool for understanding the properties of materials at the high-pressure high-temperature conditions prevalent in giant planet interiors, but properties such as solubility and phase boundaries are dependent on entropy, a quantity not directly accessible in simulation. Determining entropic properties from atomistic simulations is a difficult problem typically requiring a time-consuming integration over molecular dynamics trajectories. Here I will describe recent advances in first-principles thermodynamic calculations which substantially increase the simplicity and efficiency of thermodynamic integration and make entropic properties more readily accessible. I will also describe the use of first-principles thermodynamic calculations for understanding problems including core solubility in gas giants and superionic phase changes in ice giants, as well as future prospects for combining first-principles thermodynamics with planetary-scale models to help us understand the origin and consequences of compositional inhomogeneity in giant planet interiors.

The principle of equivalence reconsidered: assessing the relevance of the principle of equivalence in prison medicine.

PubMed

Jotterand, Fabrice; Wangmo, Tenzin

2014-01-01

In this article we critically examine the principle of equivalence of care in prison medicine. First, we provide an overview of how the principle of equivalence is utilized in various national and international guidelines on health care provision to prisoners. Second, we outline some of the problems associated with its applications, and argue that the principle of equivalence should go beyond equivalence to access and include equivalence of outcomes. However, because of the particular context of the prison environment, third, we contend that the concept of "health" in equivalence of health outcomes needs conceptual clarity; otherwise, it fails to provide a threshold for healthy states among inmates. We accomplish this by examining common understandings of the concepts of health and disease. We conclude our article by showing why the conceptualization of diseases as clinical problems provides a helpful approach in the delivery of health care in prison.

Evidence-based medicine between explicit rationing, medical deontology and rights of patients.

PubMed

Frati, P

1998-01-01

Today a "just" health policy is balanced between the problem of the allocation of scarce resources and the priority setting of services, care and cures. Despite technologies and molecular medicine, with their tendency to reach absolute prediction of disease or absence of disease and to cure with predicted efficacy, a large portion of the public refuse the results of experimental procedures and prefer to place trust in so-called alternative medicine or in drugs which are not in the official guide-lines following the principles of evidence-based medicine according to DL Sackett. Juridical problems arise between the rights of free choice of cure and social dimension of Governmental care programs, which include the maximum of benefits (i.e. effective therapies) for a pre-fixed total budget. An explicit rationing only on budgetary bases without rationalisation of medical procedures reduces the rights to care of citizens-patients. Thus, an explicit rationing-rationalisation seems to be the only procedure compatible with the interest of patients in a social security system allocating "scarce" resources.

The morality of socioscientific issues: Construal and resolution of genetic engineering dilemmas

NASA Astrophysics Data System (ADS)

Sadler, Troy D.; Zeidler, Dana L.

2004-01-01

The ability to negotiate and resolve socioscientific issues has been posited as integral components of scientific literacy. Although philosophers and science educators have argued that socioscientific issues inherently involve moral and ethical considerations, the ultimate arbiters of morality are individual decision-makers. This study explored the extent to which college students construe genetic engineering issues as moral problems. Twenty college students participated in interviews designed to elicit their ideas, reactions, and feelings regarding a series of gene therapy and cloning scenarios. Qualitative analyses revealed that moral considerations were significant influences on decision-making, indicating a tendency for students to construe genetic engineering issues as moral problems. Students engaged in moral reasoning based on utilitarian analyses of consequences as well as the application of principles. Issue construal was also influenced by affective features such as emotion and intuition. In addition to moral considerations, a series of other factors emerged as important dimensions of socioscientific decision-making. These factors included personal experiences, family biases, background knowledge, and the impact of popular culture. The implications for classroom science instruction and future research are discussed.

The Effectiveness of Art Therapy in Reducing Internalizing and Externalizing Problems of Female Adolescents.

Bazargan, Yasaman; Pakdaman, Shahla

2016-01-01

The internalizing and externalizing problems relating to childhood and adolescent have always been significant. Because there is special considerations in establishing communication with them and hence, the therapeutic methods for these problems must take into account these considerations. As establishing a therapeutic relationship is an important component of effective counseling, it seems that art therapy may help alleviate these problems. The purpose of this study is to determine the effectiveness of art therapy in reducing internalizing and externalizing problems of adolescent girls (14 - 18 years old). This is a semi-experimental study carried out in the form of a pre-test/post-test design with control group. The population of this study includes female students of Gole Laleh School of Art in district 3 of Tehran, Iran, out of which 30 students with internalizing problems and 30 individuals with externalizing problems were selected through targeted sampling. Students were randomly assigned to control and experimental groups. Experimental groups participated in 6 painting sessions designed based on Art therapy theories and previous studies. The material used for diagnosis of the problems in posttest and pretest was an Achenbach self-assessment form. Data were analyzed using a mixed analysis of variance (ANOVA). Our results showed that Art therapy significantly reduced internalizing problems (F = 17.61, P < 0.001); however, its effect in reducing externalizing problems was not significant (F = 3.93, P = 0.06). Art therapy as a practical therapeutic method can be used to improve internalizing problems. To reduce externalizing problems, more sessions may be needed. Thus, future studies are required to insure these findings.

Interaction between Vestibular Compensation Mechanisms and Vestibular Rehabilitation Therapy: 10 Recommendations for Optimal Functional Recovery

PubMed Central

Lacour, Michel; Bernard-Demanze, Laurence

2015-01-01

This review questions the relationships between the plastic events responsible for the recovery of vestibular function after a unilateral vestibular loss (vestibular compensation), which has been well described in animal models in the last decades, and the vestibular rehabilitation (VR) therapy elaborated on a more empirical basis for vestibular loss patients. The main objective is not to propose a catalog of results but to provide clinicians with an understandable view on when and how to perform VR therapy, and why VR may benefit from basic knowledge and may influence the recovery process. With this perspective, 10 major recommendations are proposed as ways to identify an optimal functional recovery. Among them are the crucial role of active and early VR therapy, coincidental with a post-lesion sensitive period for neuronal network remodeling, the instructive role that VR therapy may play in this functional reorganization, the need for progression in the VR therapy protocol, which is based mainly on adaptation processes, the necessity to take into account the sensorimotor, cognitive, and emotional profile of the patient to propose individual or “à la carte” VR therapies, and the importance of motivational and ecologic contexts. More than 10 general principles are very likely, but these principles seem crucial for the fast recovery of vestibular loss patients to ensure good quality of life. PMID:25610424

From ancient Greece to the cognitive revolution: A comprehensive view of physical rehabilitation sciences.

Martínez-Pernía, David; González-Castán, Óscar; Huepe, David

2017-02-01

The development of rehabilitation has traditionally focused on measurements of motor disorders and measurements of the improvements produced during the therapeutic process; however, physical rehabilitation sciences have not focused on understanding the philosophical and scientific principles in clinical intervention and how they are interrelated. The main aim of this paper is to explain the foundation stones of the disciplines of physical therapy, occupational therapy, and speech/language therapy in recovery from motor disorder. To reach our goals, the mechanistic view and how it is integrated into physical rehabilitation will first be explained. Next, a classification into mechanistic therapy based on an old version (automaton model) and a technological version (cyborg model) will be shown. Then, it will be shown how physical rehabilitation sciences found a new perspective in motor recovery, which is based on functionalism, during the cognitive revolution in the 1960s. Through this cognitive theory, physical rehabilitation incorporated into motor recovery of those therapeutic strategies that solicit the activation of the brain and/or symbolic processing; aspects that were not taken into account in mechanistic therapy. In addition, a classification into functionalist rehabilitation based on a computational therapy and a brain therapy will be shown. At the end of the article, the methodological principles in physical rehabilitation sciences will be explained. It will allow us to go deeper into the differences and similarities between therapeutic mechanism and therapeutic functionalism.

Purpose: To present the principles and rationale of the Proton Priority System (PROPS), a priority points framework that assigns higher scores to patients thought to more likely benefit from proton therapy, and the distribution of PROPS scores by patient characteristics Methods and Materials: We performed multivariable logistic regression to evaluate the association between PROPS scores and receipt of proton therapy, adjusted for insurance status, gender, race, geography, and the domains that inform the PROPS score. Results: Among 1529 adult patients considered for proton therapy prioritization during our Center's ramp-up phase of treatment availability, PROPS scores varied by age, diagnosis, site,more » and other PROPS domains. In adjusted analyses, receipt of proton therapy was lower for patients with non-Medicare relative to Medicare health insurance (commercial vs Medicare: adjusted odds ratio [OR] 0.47, 95% confidence interval [CI] 0.34-0.64; managed care vs Medicare: OR 0.40, 95% CI 0.28-0.56; Medicaid vs Medicare: OR 0.24, 95% CI 0.13-0.44). Proton Priority System score and age were not significantly associated with receipt of proton therapy. Conclusions: The Proton Priority System is a rationally designed and transparent system for allocation of proton therapy slots based on the best available evidence and expert opinion. Because the actual allocation of treatment slots depends mostly on insurance status, payers may consider incorporating PROPS, or its underlying principles, into proton therapy coverage policies.« less

Prevention and management of statin adverse effects: A practical approach for pharmacists.

PubMed

Barry, Arden R; Beach, Jessica E; Pearson, Glen J

2018-01-01

Statin-associated adverse effects, primarily muscle-related symptoms, occur in up to approximately one-third of patients in clinical practice. Recently, a Canadian Consensus Working Group outlined 6 key principles to assess and manage patients with goal-inhibiting statin intolerance, defined as a syndrome characterized by symptoms or biomarker abnormalities that prevent the long-term use of and adherence to indicated statin therapy, which includes a trial of at least 2 statins and precludes reversible causes of statin adverse effects. These principles ensure patients are appropriately receiving a statin and aware of both the benefits and risks of therapy. As well, they address factors that may increase the risk of statin-associated myopathy. A thorough assessment of patients' clinical and laboratory history should be performed in any patient presenting with muscle symptoms on statin therapy, followed by a systematic dechallenge/rechallenge approach. In practice, most patients with statin intolerance due to muscle symptoms will be able to tolerate another statin. This is of particular importance because of the relative paucity of compelling evidence demonstrating a cardiovascular benefit with nonstatin therapies. Pharmacists are ideally situated to provide patient education, recommend changes to therapy and monitor patients with goal-inhibiting statin intolerance.

Students' and teachers' misapplication of le chatelier's principle: Implications for the teaching of chemical equilibrium

NASA Astrophysics Data System (ADS)

Quílez-Pardo, Juan; Solaz-Portolés, Joan Josep

The aim of this article was to study the reasons, strategies, and procedures that both students and teachers use to solve some chemical equilibrium questions and problems. Inappropriate conceptions on teaching and a lack of knowledge regarding the limited usefulness of Le Chatelier's principle, with its vague and ambiguous formulation and textbook presentation, may be some of the sources of misconceptions about the prediction of the effect of changing conditions on chemical equilibrium. To diagnose misconceptions and their possible sources, a written test was developed and administered to 170 1st-year university chemistry students. A chemical equilibrium problem, relating to the students' test, was solved by 40 chemistry teachers. First, we ascertained that teacher's conceptions might influence the problem-solving strategies of the learner. Based on this first aspect, our discussion also concerns students' and teachers' misconceptions related to the Le Chatelier's principle. Misconceptions emerged through: (a) misapplication and misunderstanding of Le Chatelier's principle; (b) use of rote-learning recall and algorithmic procedures; (c) incorrect control of the variables involved; (d) limited use of the chemical equilibrium law; (e) a lack of mastery of chemical equilibrium principles and difficulty in transferring such principles to new situations. To avoid chemical equilibrium misconceptions, a specific pattern of conceptual and methodological change may be considered.Received: 16 November 1993; Revised: 21 September 1994;

McMurran, Mary; Wilmington, Rebekah

2007-01-01

Psychoeducation and social problem-solving therapy are treatment components that work well in tandem for offenders with personality disorders, hence it is worthwhile to maintain and improve their effectiveness. The aim was to seek patients' views of these therapies to contribute to their development. A Delphi survey was conducted with all 12 male inpatients of a personality disorder hospital treatment unit. Round 1 produced 30 statements for psychoeducation and 59 for social problem-solving therapy to be rated in Round 2. There was consensus at a level of 70% for all items. Both psychoeducation and social problem-solving therapies were viewed as useful by these patients. The men also suggested improvements in psychoeducation, including minimizing the delay between assessment and feedback, provision of reference material, preparation for the work and support afterwards. Areas identified for improvement in social problem-solving therapy included more frequent review of progress, greater consistency of delivery, eliciting problems more effectively, providing reference material, supporting patients in group work, and the development of an advanced therapy. A Delphi approach to evaluation of therapies with the people receiving them is not only feasible but seems to offer a practical way of making useful clinical adjustments to the work. Further research with larger samples might usefully focus on whether such an approach enhances treatment compliance. 2007 John Wiley & Sons, Ltd

Traditional Chinese Medicine, Food Therapy, and Hypertension Control: A Narrative Review of Chinese Literature.

PubMed

Zou, Ping

2016-01-01

Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the "hot" and "cold" nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control. Based on a statistical analysis of antihypertensive foods recommended in 20 books on the application of food therapy for hypertension control, the 38 most frequently recommended are celery, tomato, banana, hawthorn, garlic, onion, seaweed, apple, corn, green beans, persimmon, laver, kiwi, watermelon, eggplant, carrots, mushroom, peanut, soy products, sea cucumber, buckwheat, garland chrysanthemum, spinach, honey, dairy products, vinegar, black fungus, jellyfish, green onion, shepherd's purse, soybean, potato, pear, winter melon, bitter melon, oat, pea, and tea. Food therapy emphasizes the therapeutic effects of food, considering its nature, taste, and function on human balanced health, which leads to optimal blood pressure control. Current literature suggests that food therapy is effective in blood pressure control and can be incorporated into blood pressure self-management in the Chinese population.

The purpose of this study was to compare the clinical outcomes of classic massage to massage based on the tensegrity principle for patients with chronic idiopathic shoulder pain. Thirty subjects with chronic shoulder pain symptoms were divided into 2 groups, 15 subjects received classic (Swedish) massage to tissues surrounding the glenohumeral joint and 15 subjects received the massage using techniques based on the tensegrity principle. The tensegrity principle is based on directing treatment to the painful area and the tissues (muscles, fascia, and ligaments) that structurally support the painful area, thus treating tissues that have direct and indirect influence on the motion segment. Both treatment groups received 10 sessions over 2 weeks, each session lasted 20 minutes. The McGill Pain Questionnaire and glenohumeral ranges of motion were measured immediately before the first massage session, on the day the therapy ended 2 weeks after therapy started, and 1 month after the last massage. Subjects receiving massage based on the tensegrity principle demonstrated statistically significance improvement in the passive and active ranges of flexion and abduction of the glenohumeral joint. Pain decreased in both massage groups. This study showed increases in passive and active ranges of motion for flexion and abduction in patients who had massage based on the tensegrity principle. For pain outcomes, both classic and tensegrity massage groups demonstrated improvement. Copyright © 2013 National University of Health Sciences. Published by Mosby, Inc. All rights reserved.

Artificial Cell Therapy: New Strategies for the Therapeutic Delivery of Live Bacteria

PubMed Central

2005-01-01

There has been rapid growth in research regarding the use of live bacterial cells for therapeutic purposes. The recognition that these cells can be genetically engineered to synthesize products that have therapeutic potential has generated considerable interest and excitement among clinicians and health professionals. It is expected that a wide range of disease modifying substrates such as enzymes, hormones, antibodies, vaccines, and other genetic products will be used successfully and will impact upon health care substantially. However, a major limitation in the use of these bacterial cells is the complexity of delivering them to the correct target tissues. Oral delivery of live cells, lyophilized cells, and immobilized cells has been attempted but with limited success. Primarily, this is because bacterial cells are incapable of surviving passage through the gastrointestinal tract. In many occasions, when given orally, these cells have been found to provoke immunogenic responses that are undesirable. Recent studies show that these problems can be overcome by delivering live bacterial cells, such as genetically engineered cells, using artificial cell microcapsules. This review summarizes recent advances in the therapeutic use of live bacterial cells for therapy, discusses the principles of using artificial cells for the oral delivery of bacterial cells, outlines methods for preparing suitable artificial cells for this purpose, addresses potentials and limitations for their application in therapy, and provides insight for the future direction of this emergent and highly prospective technology.

Dopamine in the management of shock.

PubMed Central

Thompson, W L

1977-01-01

Shock is a syndrome with serious prognostic implications--the harbinger of death. Hypoperfusion of essential organs is common, though total blood flow may be significantly greater than normal. Specific therapy is directed to the specific inciting event--infection, abscess, tamponade, &c. Symptomatic therapy keeps the patient alive until we discover the specific problem or until he recovers spontaneously. The intravascular volume must be carefully monitored and corrected, using the pulmonary wedge pressure as the principal guide, and colloid osmotic pressure must be maintained. If the patient does not respond to volume augmentation alone then inotropic drugs may be needed, and of these dopamine is a selective vasodilator which redirects blood flow to the critical organs. The outstanding challenge in shock is the maldistribution of perfusion in the microvasculature. Although this may be ameliorated by the early administration of large doses of glucocorticoids, there is little convincing that these drugs constitute more than supportive therapy. Of greatest importance is reevaluation, reevaluation, and reevaluation. The patient in shock becomes a new patient every five minutes. Drugs that formerly worked, doses previously optimal--these are no guide because the situation changes so rapidly. The principles of management are to monitor vital functions, constantly vary drugs and doses, and continually attempt to put right all the parameters measured. This strategy will be more effective when we know what parameters to measure. PMID:264200

Surgery in Management of Patients with Leukaemia

PubMed Central

Spiers, A. S. D.

1973-01-01

Though leukaemia is not a “surgical” disease, the need for surgery in patients with leukaemia is increasing. Acute surgical problems in such patients present diagnostic difficulties, and accepted surgical principles do not necessarily apply in patients with very abnormal haematological and immunological features. The improved prognosis in some types of leukaemia means that elective surgical procedures, which formerly would not have been considered, may now be applicable just as they would be in patients with non-malignant conditions. Recent advances in the management of the leukaemias include several surgical procedures—for example, to facilitate intravenous or intrathecal therapy. Splenectomy is of value in chronic lymphocytic leukaemia when the correct indications are present, while early elective splenectomy, when no classical indications are present, may have a useful role in the management of patients with chronic granulocytic leukaemia.

Clinical decision making-a functional medicine perspective.

Pizzorno, Joseph E

2012-09-01

As 21st century health care moves from a disease-based approach to a more patient-centric system that can address biochemical individuality to improve health and function, clinical decision making becomes more complex. Accentuating the problem is the lack of a clear standard for this more complex functional medicine approach. While there is relatively broad agreement in Western medicine for what constitutes competent assessment of disease and identification of related treatment approaches, the complex functional medicine model posits multiple and individualized diagnostic and therapeutic approaches, most or many of which have reasonable underlying science and principles, but which have not been rigorously tested in a research or clinical setting. This has led to non-rigorous thinking and sometimes to uncritical acceptance of both poorly documented diagnostic procedures and ineffective therapies, resulting in less than optimal clinical care.

Fetal Therapy for Down Syndrome: Report of Three Cases and a Review of the Literature.

PubMed

Baggot, Patrick James; Baggot, Rocel Medina

2017-01-01

Down syndrome (trisomy 21) is a well-known cause of mental retardation. It can be diagnosed in early pregnancy. Scientists have made great strides in outlining the pathophysiologic mechanisms of mental retardation in Down syndrome. Much less has been published on human therapy. To our knowledge, these are the first published cases of fetal therapy for Down syndrome. Reports of three cases. In all cases, treatment was both biochemical (e.g. nutritional) and educational. In all cases, treatment was both before and after birth. All children lacked the characteristic faces usually seen in the children with Down syndrome. This suggests a treatment effect before birth. All children had better than expected development. Enhancement of development is proposed as a new therapeutic principle. Developing neurons exchange neurotrophic factors during development when they give or receive stimulation from other neurons. Neurons which receive neurotrophic stimulation survive, and those, which do not, are lost to apoptosis. The developmental therapeutic principle seeks to optimize brain development. Biochemical inputs (neurotransmitters, drugs, hormones, nutrients) and functional stimulation are integrated to optimize the growth and survival of neurons individually; other cells; subcellular organelles; and the brain as a whole. Treatment may be before and after birth, both biochemical and functional. These principles may be applied to Down syndrome, other conditions, and normal fetuses or children.

United we stand: emphasizing commonalities across cognitive-behavioral therapies.

Mennin, Douglas S; Ellard, Kristen K; Fresco, David M; Gross, James J

2013-06-01

Cognitive behavioral therapy (CBT) has a rich history of alleviating the suffering associated with mental disorders. Recently, there have been exciting new developments, including multicomponent approaches, incorporated alternative therapies (e.g., meditation), targeted and cost-effective technologies, and integrated biological and behavioral frameworks. These field-wide changes have led some to emphasize the differences among variants of CBT. Here, we draw attention to commonalities across cognitive-behavioral therapies, including shared goals, change principles, and therapeutic processes. Specifically, we offer a framework for examining common CBT characteristics that emphasizes behavioral adaptation as a unifying goal and three core change principles, namely (a) context engagement to promote adaptive imagining and enacting of new experiences; (b) attention change to promote adaptive sustaining, shifting, and broadening of attention; and (c) cognitive change to promote adaptive perspective taking on events so as to alter verbal meanings. Further, we argue that specific intervention components, including behavioral exposure/activation, attention training, acceptance/tolerance, decentering/defusion, and cognitive reframing, may be emphasized to a greater or lesser degree by different treatment packages but are still fundamentally common therapeutic processes that are present across approaches and are best understood by their relationships to these core CBT change principles. We conclude by arguing for shared methodological and design frameworks for investigating unique and common characteristics to advance a unified and strong voice for CBT in a widening, increasingly multimodal and interdisciplinary, intervention science.

Young children's use of derived fact strategies for addition and subtraction

PubMed Central

Dowker, Ann

2014-01-01

Forty-four children between 6;0 and 7;11 took part in a study of derived fact strategy use. They were assigned to addition and subtraction levels on the basis of calculation pretests. They were then given Dowker's (1998) test of derived fact strategies in addition, involving strategies based on the Identity, Commutativity, Addend +1, Addend −1, and addition/subtraction Inverse principles; and test of derived fact strategies in subtraction, involving strategies based on the Identity, Minuend +1, Minuend −1, Subtrahend +1, Subtrahend −1, Complement and addition/subtraction Inverse principles. The exact arithmetic problems given varied according to the child's previously assessed calculation level and were selected to be just a little too difficult for the child to solve unaided. Children were given the answer to a problem and then asked to solve another problem that could be solved quickly by using this answer, together with the principle being assessed. The children also took the WISC Arithmetic subtest. Strategies differed greatly in difficulty, with Identity being the easiest, and the Inverse and Complement principles being most difficult. The Subtrahend +1 and Subtrahend −1 problems often elicited incorrect strategies based on an overextension of the principles of addition to subtraction. It was concluded that children may have difficulty with understanding and applying the relationships between addition and subtraction. Derived fact strategy use was significantly related to both calculation level and to WISC Arithmetic scaled score. PMID:24431996

Variational principle for the Navier-Stokes equations.

PubMed

Kerswell, R R

1999-05-01

A variational principle is presented for the Navier-Stokes equations in the case of a contained boundary-driven, homogeneous, incompressible, viscous fluid. Based upon making the fluid's total viscous dissipation over a given time interval stationary subject to the constraint of the Navier-Stokes equations, the variational problem looks overconstrained and intractable. However, introducing a nonunique velocity decomposition, u(x,t)=phi(x,t) + nu(x,t), "opens up" the variational problem so that what is presumed a single allowable point over the velocity domain u corresponding to the unique solution of the Navier-Stokes equations becomes a surface with a saddle point over the extended domain (phi,nu). Complementary or dual variational problems can then be constructed to estimate this saddle point value strictly from above as part of a minimization process or below via a maximization procedure. One of these reduced variational principles is the natural and ultimate generalization of the upper bounding problem developed by Doering and Constantin. The other corresponds to the ultimate Busse problem which now acts to lower bound the true dissipation. Crucially, these reduced variational problems require only the solution of a series of linear problems to produce bounds even though their unique intersection is conjectured to correspond to a solution of the nonlinear Navier-Stokes equations.

Complexity and compositionality in fluid intelligence.

Duncan, John; Chylinski, Daphne; Mitchell, Daniel J; Bhandari, Apoorva

2017-05-16

Compositionality, or the ability to build complex cognitive structures from simple parts, is fundamental to the power of the human mind. Here we relate this principle to the psychometric concept of fluid intelligence, traditionally measured with tests of complex reasoning. Following the principle of compositionality, we propose that the critical function in fluid intelligence is splitting a complex whole into simple, separately attended parts. To test this proposal, we modify traditional matrix reasoning problems to minimize requirements on information integration, working memory, and processing speed, creating problems that are trivial once effectively divided into parts. Performance remains poor in participants with low fluid intelligence, but is radically improved by problem layout that aids cognitive segmentation. In line with the principle of compositionality, we suggest that effective cognitive segmentation is important in all organized behavior, explaining the broad role of fluid intelligence in successful cognition.

Principle problems of a basic health care area (Lérida) are identified. This area, which has a patient case load of 22,244 people, was studied during the winter of 1993-94 by using information from various sources. Results indicate that the population of this community are basically young, urban, have a high cultural and social level, and are mostly employed. The principle causes of mortality are the same as in the rest of Cataluña. Diseases that cause the most working days lost to illness are: respiratory, mental and bone-joint problems. The most frequent diseases seen in the clinic are: hypertension, respiratory infections, endocrine and mental. An overall look at the state of health of these patients show that the principle problems are: tobacco use, high blood pressure, arthritis, lumbago, depression, stroke, diabetes and breast cancer.

The application of the speed-gradient (SG) principle to the non-equilibrium distribution systems far away from thermodynamic equilibrium is investigated. The options for applying the SG principle to describe the non-equilibrium transport processes in real-world environments are discussed. Investigation of a non-equilibrium system's evolution at different scale levels via the SG principle allows for a fresh look at the thermodynamics problems associated with the behaviour of the system entropy. Generalized dynamic equations for finite and infinite number of constraints are proposed. It is shown that the stationary solution to the equations, resulting from the SG principle, entirely coincides with the locally equilibrium distribution function obtained by Zubarev. A new approach to describe time evolution of systems far from equilibrium is proposed based on application of the SG principle at the intermediate scale level of the system's internal structure. The problem of the high-rate shear flow of viscous fluid near the rigid plane plate is discussed. It is shown that the SG principle allows closed mathematical models of non-equilibrium processes to be constructed.This article is part of the themed issue 'Horizons of cybernetical physics'. © 2017 The Author(s).

2018-02-22

Stress is one of the world's largest health problems, leading to exhaustion, burnout, anxiety, a weak immune system, or even organ damage. In Germany, stress-induced work absenteeism costs about 20 billion Euros per year. Therefore, it is not surprising that the Central Federal Association of the public Health Insurance Funds in Germany ascribes particular importance to stress prevention and stress management as well as health enhancing measures. Building on current integrative and embodied stress theories, Creative Arts Therapies (CATs) or arts interventions are an innovative way to prevent stress and improve stress management. CATs encompass art, music, dance/movement, and drama therapy as their four major modalities. In order to obtain an overview of CATs and arts interventions' efficacy in the context of stress reduction and management, we conducted a systematic review with a search in the following data bases: Academic Search Complete, ERIC, Medline, Psyndex, PsycINFO and SocINDEX. Studies were included employing the PICOS principle and rated according to their evidence level. We included 37 studies, 73% of which were randomized controlled trials. 81.1% of the included studies reported a significant reduction of stress in the participants due to interventions of one of the four arts modalities.

To create a comparative referential system for syndrome classification study by viewing from the thinking characteristics of TCM on syndrome differentiation dependent therapy (SDDT), through analyzing the thinking process of SDDT, and the basic features of disease, syndrome and prescription, combining the basic principles of modern evidence-based medicine and feasibility of establishing integrative disease-syndrome animal model. The practice of creating a comparative referential system based on clinical efficacy of prescription was discussed around syndrome pathogenesis and its relationship with disease and prescription, which was one of the important scientific problems in TCM syndrome study. The authors hold that, it may be one of the available approaches for the present study on integration of disease with syndrome by way of insisting on the thinking pathway of stressing the characteristics of TCM and intermerging with modern scientific design; on taking the efficacy of prescription as the comparative reference system to accumulate and improve unceasingly according to the TCM method of syndrome diagnosis inferred from effect of prescription with reverse thought (i.e., to differentiate syndrome from the effect of prescription), and thus build up the syndrome diagnostic standard on the solid clinical and scientific base.

Gene therapy for bone healing.

PubMed

Evans, Christopher H

2010-06-23

Clinical problems in bone healing include large segmental defects, spinal fusions, and the nonunion and delayed union of fractures. Gene-transfer technologies have the potential to aid healing by permitting the local delivery and sustained expression of osteogenic gene products within osseous lesions. Key questions for such an approach include the choice of transgene, vector and gene-transfer strategy. Most experimental data have been obtained using cDNAs encoding osteogenic growth factors such as bone morphogenetic protein-2 (BMP-2), BMP-4 and BMP-7, in conjunction with both nonviral and viral vectors using in vivo and ex vivo delivery strategies. Proof of principle has been convincingly demonstrated in small-animal models. Relatively few studies have used large animals, but the results so far are encouraging. Once a reliable method has been developed, it will be necessary to perform detailed pharmacological and toxicological studies, as well as satisfy other demands of the regulatory bodies, before human clinical trials can be initiated. Such studies are very expensive and often protracted. Thus, progress in developing a clinically useful gene therapy for bone healing is determined not only by scientific considerations, but also by financial constraints and the ambient regulatory environment.

2014-11-02

Focusing on the benefits of patients with rare disease the authors analysed the aspects of orphan medicines financed in the frame of the Hungarian social insurance system in 2012 in order to make the consumption more rational, transparent and predictable. Most of the orphan drugs were financed in the frame of compassionate use by the reimbursement system. Consequently, a great deal of crucial problems occurred in relation to the unconventional subsidized method, especially in the case of the highest cost enzyme replacement therapies. On the base of the findings, proposals of the authors are presented for access to orphan drugs, fitting to the specific professional, economical and ethical aspects of this unique field of the health care system. The primary goal is to provide a suitable subsidized method for the treatment of rare disease patients with unmet medical needs. The financial modification of orphans became indispensible in Hungary. Professionals from numerous fields dealing with rare disease patients' care expressed agreement on the issue. Transforming the orphan medicines' financial structure has been initiated according to internationally shared principles.

A solution to the biodiversity paradox by logical deterministic cellular automata.

PubMed

Kalmykov, Lev V; Kalmykov, Vyacheslav L

2015-06-01

The paradox of biological diversity is the key problem of theoretical ecology. The paradox consists in the contradiction between the competitive exclusion principle and the observed biodiversity. The principle is important as the basis for ecological theory. On a relatively simple model we show a mechanism of indefinite coexistence of complete competitors which violates the known formulations of the competitive exclusion principle. This mechanism is based on timely recovery of limiting resources and their spatio-temporal allocation between competitors. Because of limitations of the black-box modeling there was a problem to formulate the exclusion principle correctly. Our white-box multiscale model of two-species competition is based on logical deterministic individual-based cellular automata. This approach provides an automatic deductive inference on the basis of a system of axioms, and gives a direct insight into mechanisms of the studied system. It is one of the most promising methods of artificial intelligence. We reformulate and generalize the competitive exclusion principle and explain why this formulation provides a solution of the biodiversity paradox. In addition, we propose a principle of competitive coexistence.

Overview of the phytomedicine approaches against Helicobacter pylori

PubMed Central

Vale, Filipa F; Oleastro, Mónica

2014-01-01

Helicobacter pylori (H. pylori) successfully colonizes the human stomach of the majority of the human population. This infection always causes chronic gastritis, but may evolve to serious outcomes, such as peptic ulcer, gastric carcinoma or mucosa-associated lymphoid tissue lymphoma. H. pylori first line therapy recommended by the Maastricht-4 Consensus Report comprises the use of two antibiotics and a proton-pomp inhibitor, but in some regions failure associated with this treatment is already undesirable high. Indeed, treatment failure is one of the major problems associated with H. pylori infection and is mainly associated with bacterial antibiotic resistance. In order to counteract this situation, some effort has been allocated during the last years in the investigation of therapeutic alternatives beyond antibiotics. These include vaccines, probiotics, photodynamic inactivation and phage therapy, which are briefly revisited in this review. A particular focus on phytomedicine, also described as herbal therapy and botanical therapy, which consists in the use of plant extracts for medicinal purposes, is specifically addressed, namely considering its history, category of performed studies, tested compounds, active principle and mode of action. The herbs already experienced are highly diverse and usually selected from products with a long history of employment against diseases associated with H. pylori infection from each country own folk medicine. The studies demonstrated that many phytomedicine products have an anti-H. pylori activity and gastroprotective action. Although the mechanism of action is far from being completely understood, current knowledge correlates the beneficial action of herbs with inhibition of essential H. pylori enzymes, modulation of the host immune system and with attenuation of inflammation.

Cost effectiveness of treatment for alcohol problems: findings of the randomised UK alcohol treatment trial (UKATT).

PubMed

2005-09-10

To compare the cost effectiveness of social behaviour and network therapy, a new treatment for alcohol problems, with that of the proved motivational enhancement therapy. Cost effectiveness analysis alongside a pragmatic randomised trial. Seven treatment sites around Birmingham, Cardiff, and Leeds. 742 clients with alcohol problems; 617 (83.2%) were interviewed at 12 months and full economic data were obtained on 608 (98.5% of 617). Main economic measures Quality adjusted life years (QALYs), costs of trial treatments, and consequences for public sector resources (health care, other alcohol treatment, social services, and criminal justice services). Both therapies saved about five times as much in expenditure on health, social, and criminal justice services as they cost. Neither net savings nor cost effectiveness differed significantly between the therapies, despite the average cost of social behaviour and network therapy (221 pounds sterling; 385 dollars; 320 euros) being significantly more than that of motivational enhancement therapy (129 pounds sterling). If a QALY were worth 30,000 pounds sterling, then the motivational therapy would have 58% chance of being more cost effective than the social therapy, and the social therapy would have 42% chance of being more cost effective than the motivational therapy. Participants reported highly significant reductions in drinking and associated problems and costs. The novel social behaviour and network therapy did not differ significantly in cost effectiveness from the proved motivational enhancement therapy.

Application of TRIZ approach to machine vibration condition monitoring problems

Up to now machine condition monitoring has not been seriously approached by TRIZ1TRIZ= Russian acronym for Inventive Problem Solving System, created by G. Altshuller ca 50 years ago. users, and the knowledge of TRIZ methodology has not been applied there intensively. However, there are some introductory papers of present author posted on Diagnostic Congress in Cracow (Cempel, in press [11]), and Diagnostyka Journal as well. But it seems to be further need to make such approach from different sides in order to see, if some new knowledge and technology will emerge. In doing this we need at first to define the ideal final result (IFR) of our innovation problem. As a next we need a set of parameters to describe the problems of system condition monitoring (CM) in terms of TRIZ language and set of inventive principles possible to apply, on the way to IFR. This means we should present the machine CM problem by means of contradiction and contradiction matrix. When specifying the problem parameters and inventive principles, one should use analogy and metaphorical thinking, which by definition is not exact but fuzzy, and leads sometimes to unexpected results and outcomes. The paper undertakes this important problem again and brings some new insight into system and machine CM problems. This may mean for example the minimal dimensionality of TRIZ engineering parameter set for the description of machine CM problems, and the set of most useful inventive principles applied to given engineering parameter and contradictions of TRIZ.

Problem solving is a complex process valuable in everyday life and crucial for learning in the STEM fields. To support the development of problem-solving skills it is important for researchers and curriculum developers to have practical tools that can measure the difference between novice and expert problem-solving performance in authentic classroom work. It is also useful if such tools can be employed by instructors to guide their pedagogy. We describe the design, development, and testing of a simple rubric to assess written solutions to problems given in undergraduate introductory physics courses. In particular, we present evidence for the validity, reliability, and utility of the instrument. The rubric identifies five general problem-solving processes and defines the criteria to attain a score in each: organizing problem information into a Useful Description, selecting appropriate principles (Physics Approach), applying those principles to the specific conditions in the problem (Specific Application of Physics), using Mathematical Procedures appropriately, and displaying evidence of an organized reasoning pattern (Logical Progression).

Animal-Assisted Therapy (AAT) is a fairly new practice whose underlying principles date back to the beginning of time. Man has always found companionship in animals, but now researchers, educators and therapists are finding that by drawing on that comfort, children and adults can attack physical, mental and emotional issues. The use of animals in…

Souidi, Mohammed El Habib; Songhao, Piao; Guo, Li; Lin, Chang

2016-11-01

An approach of cooperative pursuit for multiple mobile targets based on multi-agents system is discussed. In this kind of problem the pursuit process is divided into two kinds of tasks. The first one (coalition problem) is designed to solve the problem of the pursuit team formation. To achieve this mission, we used an innovative method based on a dynamic organisation and reorganisation of the pursuers' groups. We introduce our coalition strategy extended from the organisational agent, group, role model by assigning an access mechanism to the groups inspired by fuzzy logic principles. The second task (motion problem) is the treatment of the pursuers' motion strategy. To manage this problem we applied the principles of the Markov decision process. Simulation results show the feasibility and validity of the given proposal.

Optimization of the interplanetary trajectories of spacecraft with a solar electric propulsion power plant of minimal power

Ivanyukhin, A. V.; Petukhov, V. G.

2016-12-01

The problem of optimizing the interplanetary trajectories of a spacecraft (SC) with a solar electric propulsion system (SEPS) is examined. The problem of investigating the permissible power minimum of the solar electric propulsion power plant required for a successful flight is studied. Permissible ranges of thrust and exhaust velocity are analyzed for the given range of flight time and final mass of the spacecraft. The optimization is performed according to Portnyagin's maximum principle, and the continuation method is used for reducing the boundary problem of maximal principle to the Cauchy problem and to study the solution/ parameters dependence. Such a combination results in the robust algorithm that reduces the problem of trajectory optimization to the numerical integration of differential equations by the continuation method.

Family therapy in treatment of the deaf: a case report.

PubMed

Shapiro, R J; Harris, R I

1976-03-01

Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.

Clarity of objectives and working principles enhances the success of biomimetic programs.

2017-09-26

Biomimetics, the transfer of functional principles from living systems into product designs, is increasingly being utilized by engineers. Nevertheless, recurring problems must be overcome if it is to avoid becoming a short-lived fad. Here we assess the efficiency and suitability of methods typically employed by examining three flagship examples of biomimetic design approaches from different disciplines: (1) the creation of gecko-inspired adhesives; (2) the synthesis of spider silk, and (3) the derivation of computer algorithms from natural self-organizing systems. We find that identification of the elemental working principles is the most crucial step in the biomimetic design process. It bears the highest risk of failure (e.g. losing the target function) due to false assumptions about the working principle. Common problems that hamper successful implementation are: (i) a discrepancy between biological functions and the desired properties of the product, (ii) uncertainty about objectives and applications, (iii) inherent limits in methodologies, and (iv) false assumptions about the biology of the models. Projects that aim for multi-functional products are particularly challenging to accomplish. We suggest a simplification, modularisation and specification of objectives, and a critical assessment of the suitability of the model. Comparative analyses, experimental manipulation, and numerical simulations followed by tests of artificial models have led to the successful extraction of working principles. A searchable database of biological systems would optimize the choice of a model system in top-down approaches that start at an engineering problem. Only when biomimetic projects become more predictable will there be wider acceptance of biomimetics as an innovative problem-solving tool among engineers and industry.

2013-03-01

The chronic worldwide lack of organs for transplantation and the continuing improvement of strategies for in situ organ preservation have led to renewed interest in elective non-therapeutic ventilation of potential organ donors. Two types of situation may be eligible for elective intensive care: patients definitely evolving towards brain death and patients suitable as controlled non-heart beating organ donors after life-supporting therapies have been assessed as futile and withdrawn. Assessment of the ethical acceptability and the risks of these strategies is essential. We here offer such an ethical assessment using the four principles of medical ethics of Beauchamp and Childress applying them in their broadest sense so as to include patients and their families, their caregivers, other potential recipients of intensive care, and indeed society as a whole. The main ethical problems emerging are the definition of beneficence for the potential organ donor, the dilemma between the duty to respect a dying patient's autonomy and the duty not to harm him/her, and the possible psychological and social harm for families, caregivers other potential recipients of therapeutic intensive care, and society more generally. Caution is expressed about the ethical acceptability of elective non-therapeutic ventilation, along with some proposals for precautionary measures to be taken if it is to be implemented.

Management of minor acute cutaneous wounds: importance of wound healing in a moist environment.

PubMed

Korting, H C; Schöllmann, C; White, R J

2011-02-01

Moist wound care has been established as standard therapy for chronic wounds with impaired healing. Healing in acute wounds, in particular in minor superficial acute wounds - which indeed are much more numerous than chronic wounds - is often taken for granted because it is assumed that in those wounds normal phases of wound healing should run per se without any problems. But minor wounds such as small cuts, scraps or abrasions also need proper care to prevent complications, in particular infections. Local wound care with minor wounds consists of thorough cleansing with potable tap water or normal saline followed by the application of an appropriate dressing corresponding to the principles of moist wound treatment. In the treatment of smaller superficial wounds, it appears advisable to limit the choice of dressing to just a few products that fulfil the principles of moist wound management and are easy to use. Hydroactive colloid gels combining the attributes of hydrocolloids and hydrogels thus being appropriate for dry and exuding wounds appear especially suitable for this purpose - although there is still a lack of data from systematic studies on the effectiveness of these preparations. © 2010 The Authors.

Forthcoming ethical issues in biological psychiatry.

Helmchen, Hanfried

2005-01-01

Ethical issues in biological psychiatry are framed by (i) progress in the neurosciences, and (ii) a changing socio-cultural context. With regard to forthcoming neurotechniques to modify specifically defined brain functions by pharmacological substances with selective effects, by activating neuroplasticity including neurogenesis, or by implantation of neuronal tissues or computer-brain interfaces, etc., ethical problems will develop (i) at the border between therapy of diseases and enhancement of abilities in healthy people with regard to effects on society (e.g., social justice: equal access, loss of societal diversity) as well as on human value systems (e.g., personality, efforts, conditio humana), and (ii) at the border between the medical system and the wellness market with regard to financing what by whom? Ethical dilemmas in psychiatry develop (i) between the individual's best and the common good (demanded from outside medicine), (ii) among different ethical principles (inside medicine), iii) if solutions are influenced by personal reasons without observing ethical principles. Ethical guidelines are necessary for ethical orientation, but may protect against misconduct only (i) if psychiatrists are educated in ethics and (ii) if psychiatric acting is under continuous debate (by ethical review boards or the public). Thus, if we psychiatrists will become ethically sensitive by reflecting and perhaps solving our current ethical dilemmas we will be prepared to deal with forthcoming ethical issues in biological psychiatry.

2015-02-01

The application of lean principles to continuous renal replacement therapy (CRRT) processes in an academic medical center is described. A manual audit over six consecutive weeks revealed that 133 5-L bags of CRRT solution were discarded after being dispensed from pharmacy but before clinical use. Lean principles were used to examine the workflow for CRRT preparation and develop and implement an intervention. An educational program was developed to encourage and enhance direct communication between nursing and pharmacy about changes in a patient's condition or CRRT order. It was through this education program that the reordering workflow shifted from nurses to pharmacy technicians. The primary outcome was the number of CRRT solution bags delivered in the preintervention and postintervention periods. Nurses and pharmacy technicians were surveyed to determine their satisfaction with the workflow change. After implementation of lean principles, the mean number of CRRT solution bags dispensed per day of CRRT decreased substantially. Respondents' overall satisfaction with the CRRT solution preparation process increased during the postintervention period, and the satisfaction scores for each individual component of the workflow after implementation of lean principles. The decreased solution waste resulted in projected annual cost savings exceeding $70,000 in product alone. The use of lean principles to identify medication waste in the CRRT workflow and implementation of an intervention to shift the workload from intensive care unit nurses to pharmacy technicians led to reduced CRRT solution waste, improved efficiency of CRRT workflow, and increased satisfaction among staff.

Variational Principles for Buckling of Microtubules Modeled as Nonlocal Orthotropic Shells

PubMed Central

2014-01-01

A variational principle for microtubules subject to a buckling load is derived by semi-inverse method. The microtubule is modeled as an orthotropic shell with the constitutive equations based on nonlocal elastic theory and the effect of filament network taken into account as an elastic surrounding. Microtubules can carry large compressive forces by virtue of the mechanical coupling between the microtubules and the surrounding elastic filament network. The equations governing the buckling of the microtubule are given by a system of three partial differential equations. The problem studied in the present work involves the derivation of the variational formulation for microtubule buckling. The Rayleigh quotient for the buckling load as well as the natural and geometric boundary conditions of the problem is obtained from this variational formulation. It is observed that the boundary conditions are coupled as a result of nonlocal formulation. It is noted that the analytic solution of the buckling problem for microtubules is usually a difficult task. The variational formulation of the problem provides the basis for a number of approximate and numerical methods of solutions and furthermore variational principles can provide physical insight into the problem.

McCormick, Thomas R

2010-10-01

Although the use of cochlear implants as a treatment designed to help deaf individuals hear has a relatively brief history, the use of this therapy has given rise to a number of ethical conflicts. This article identifies ethical conflicts in cochlear implantation therapy and shows how ethical principles that are commonly accepted in health care ethics may guide decision making in resolving these issues. Furthermore, clinicians are often confronted with particular cases in which ethical conflicts arise. A useful paradigm for the clinical context, the 4-box method, is offered as a means of organizing the facts of a "case" so that the important facts are considered, and a principled approach to decision making can be used in working toward a resolution.

A Framework for Fibromyalgia Management for Primary Care Providers

Arnold, Lesley M.; Clauw, Daniel J.; Dunegan, L. Jean; Turk, Dennis C.

2012-01-01

Fibromyalgia is a chronic widespread pain disorder commonly associated with comorbid symptoms, including fatigue and nonrestorative sleep. As in the management of other chronic medical disorders, the approach for fibromyalgia management follows core principles of comprehensive assessment, education, goal setting, multimodal treatment including pharmacological (eg, pregabalin, duloxetine, milnacipran) and nonpharmacological therapies (eg, physical activity, behavioral therapy, sleep hygiene, education), and regular education and monitoring of treatment response and progress. Based on these core management principles, this review presents a framework for primary care providers through which they can develop a patient-centered treatment program for patients with fibromyalgia. This proactive and systematic treatment approach encourages ongoing education and patient self-management and is designed for use in the primary care setting. PMID:22560527

2008-09-01

The widespread availability of the Internet offers opportunities for improving access to therapy for people with mental health problems. There is a seemingly infinite supply of Internet-based interventions available on the World Wide Web. The aim of the present study is to systematically assess the methodological quality of randomized controlled trials (RCTs) concerning e-therapy for mental health problems. Two reviewers independently assessed the methodological quality of the RCTs, based on a list of criteria for the methodological quality assessment as recommended by the Cochrane Back Review Group. The search yielded 14 papers that reported RCTs concerning e-therapy for mental-health problems. The methodological quality of studies included in this review was generally low. It is concluded that e-therapy may turn out to be an appropriate therapeutic entity, but the evidence needs to be more convincing. Recommendations are made concerning the method of reporting RCTs and the need to add some content items to an e-therapy study.

Principles for system level electrochemistry

Thaller, L. H.

1986-01-01

The higher power and higher voltage levels anticipated for future space missions have required a careful review of the techniques currently in use to preclude battery problems that are related to the dispersion characteristics of the individual cells. Not only are the out-of-balance problems accentuated in these larger systems, but the thermal management considerations also require a greater degree of accurate design. Newer concepts which employ active cooling techniques are being developed which permit higher rates of discharge and tighter packing densities for the electrochemical components. This paper will put forward six semi-independent principles relating to battery systems. These principles will progressively address cell, battery and finally system related aspects of large electrochemical storage systems.

A Look to Future Directions in Gene Therapy Research for Monogenic Diseases

Porteus, Matthew H; Connelly, Jon P; Pruett, Shondra M

2006-01-01

The concept of gene therapy has long appealed to biomedical researchers and clinicians because it promised to treat certain diseases at their origins. In the last several years, there have been several trials in which patients have benefited from gene therapy protocols. This progress, however, has revealed important problems, including the problem of insertional oncogenesis. In this review, which focuses on monogenic diseases, we discuss the problem of insertional oncogenesis and identify areas for future research, such as developing more quantitative assays for risk and efficacy, and ways of minimizing the genotoxic effects of gene therapy protocols, which will be important if gene therapy is to fulfill its conceptual promise.

Relationship problems and depression often influence one another in a bidirectional, recursive fashion. Results from several clinical trials have demonstrated that couple therapy is effective in improving depression and reducing relationship problems. In this article, we describe an approach to working with depression in partnered individuals who are also unhappy in their relationship. This cognitive-behavior approach strives to (a) eliminate major stressors and reestablish positive activities in the relationship, (b) improve communication and problem solving in the relationship, and (c) solidify gains made in therapy and prevent relapse. The typical course of therapy is described and demonstrated in a case illustration. Couple therapy is a promising treatment for depressed individuals in distressed relationships. © 2012 Wiley Periodicals, Inc.

Conceptual problem solving in high school physics

2015-12-01

Problem solving is a critical element of learning physics. However, traditional instruction often emphasizes the quantitative aspects of problem solving such as equations and mathematical procedures rather than qualitative analysis for selecting appropriate concepts and principles. This study describes the development and evaluation of an instructional approach called Conceptual Problem Solving (CPS) which guides students to identify principles, justify their use, and plan their solution in writing before solving a problem. The CPS approach was implemented by high school physics teachers at three schools for major theorems and conservation laws in mechanics and CPS-taught classes were compared to control classes taught using traditional problem solving methods. Information about the teachers' implementation of the approach was gathered from classroom observations and interviews, and the effectiveness of the approach was evaluated from a series of written assessments. Results indicated that teachers found CPS easy to integrate into their curricula, students engaged in classroom discussions and produced problem solutions of a higher quality than before, and students scored higher on conceptual and problem solving measures.

Rational design and adaptive management of combination therapies for Hepatitis C virus infection

Recent discoveries of direct acting antivirals against Hepatitis C virus (HCV) have raised hopes of effective treatment via combination therapies. Yet rapid evolution and high diversity of HCV populations, combined with the reality of suboptimal treatment adherence, make drug resistance a clinical and public health concern. We develop a general model incorporating viral dynamics and pharmacokinetics/ pharmacodynamics to assess how suboptimal adherence affects resistance development and clinical outcomes. We derive design principles and adaptive treatment strategies, identifying a high-risk period when missing doses is particularly risky for de novo resistance, and quantifying the number of additional doses needed to compensatemore » when doses are missed. Using data from large-scale resistance assays, we demonstrate that the risk of resistance can be reduced substantially by applying these principles to a combination therapy of daclatasvir and asunaprevir. By providing a mechanistic framework to link patient characteristics to the risk of resistance, these findings show the potential of rational treatment design.« less

[History of conservative spinal therapy].

Kladny, B

2015-12-01

Hippocrates was the first to intensively describe and document the principles for the treatment of injuries and diseases of the spine. His principles for abrupt treatment of the "hunchback" were followed by physicians even up to the end of the nineteenth century. The non-operative treatment of scoliosis was improved in the beginning of the sixteenth century by the introduction of mechanical devices that started the development of corsets which are still in use in modern scoliosis treatment. Stretching beds were only in temporary use. With the beginning of the nineteenth century gymnastics and physiotherapy became more and more important. Manual therapy was exercised by physicians until the late Middle Ages. After a long period of time in which bonesetters and other laymen performed manual therapy it was professionalized at the end of the nineteenth century again by the introduction of osteopathy and chiropractic. In Germany the development and introduction of manual treatment started relatively late in the twentieth century, predominantly as manual medicine.

Clinical practice guidelines are a tool to assist with clinical decision making. They provide information about the care for a condition and make recommendations based on research evidence, which can be adapted locally. A focus group within the Allied Health Interest Group of the Australian and New Zealand Burn Association has compiled the "Occupational Therapy and Physiotherapy for the Patient with Burns--Principles and Management Guidelines." These guidelines are designed as a practical guide to the relevant clinical knowledge and therapy intervention techniques required for effective patient management. Content areas include respiratory management, edema management, splinting and positioning, physical function (mobility, function, exercise), scar management, and psychosocial and mutual elements. The document has undergone extensive review by members of the Australian and New Zealand Burn Association to ensure clarity, internal consistency, and acceptability. The guidelines have been endorsed by the Australian and New Zealand Burn Association. An abridged version of the guidelines is included in this article, with the full document available from www.anzba.org.au.

2009-12-01

In Germany there is an increasing importance of home health care and nurses that are employed in the home care sector often have to face ethical issues. The purpose of this ethnographic study was to explore moral problems in the daily practice of these nurses. The method used was qualitative interviews with 20 nurses which have been analysed by content analysis. The results showed that the ethical principle of beneficence was the core concept for the participants. Moral problems arise when nurses cannot act in accordance to this principle or when they cannot determine the good in a situation. In particular, there were four types of moral problems: "beneficence vs. autonomy", "beneficence vs. justice", "beneficence vs. loyalty" and "The good cannot be determined". The way nurses in home health care address moral problems should be improved. Some participants lack ethical competencies. Furthermore, appropriate support services for dealing with moral problems have to be designed.

In this article, we introduce a perturbed system of generalized mixed quasi-equilibrium-like problems involving multi-valued mappings in Hilbert spaces. To calculate the approximate solutions of the perturbed system of generalized multi-valued mixed quasi-equilibrium-like problems, firstly we develop a perturbed system of auxiliary generalized multi-valued mixed quasi-equilibrium-like problems, and then by using the celebrated Fan-KKM technique, we establish the existence and uniqueness of solutions of the perturbed system of auxiliary generalized multi-valued mixed quasi-equilibrium-like problems. By deploying an auxiliary principle technique and an existence result, we formulate an iterative algorithm for solving the perturbed system of generalized multi-valued mixed quasi-equilibrium-like problems. Lastly, we study the strong convergence analysis of the proposed iterative sequences under monotonicity and some mild conditions. These results are new and generalize some known results in this field.

Described are the theoretical development and computer implementation of reliable and efficient methods for the analysis of coupled mechanical problems that involve the interaction of mechanical, thermal, phase-change and electromag subproblems. The focus application has been the modeling of superconductivity and associated quantum-state phase change phenomena. In support of this objective the work has addressed the following issues: (1) development of variational principles for finite elements, (2) finite element modeling of the electromagnetic problem, (3) coupling of thermel and mechanical effects, and (4) computer implementation and solution of the superconductivity transition problem. The main accomplishments have been: (1) the development of the theory of parametrized and gauged variational principles, (2) the application of those principled to the construction of electromagnetic, thermal and mechanical finite elements, and (3) the coupling of electromagnetic finite elements with thermal and superconducting effects, and (4) the first detailed finite element simulations of bulk superconductors, in particular the Meissner effect and the nature of the normal conducting boundary layer. The theoretical development is described in two volumes. Volume 1 describes mostly formulation specific problems. Volume 2 describes generalization of those formulations.

Scoring systems are used in all diagnostic areas of medicine. Several parameters are evaluated and rated with points according to their value in order to simplify a complex clinical situation with a score. The application ranges from the classification of disease severity through determining the number of staff for the intensive care unit (ICU) to the evaluation of new therapies under study conditions. Since the introduction of scoring systems in the 1980's a variety of different score models has been developed. The scoring systems that are employed in intensive care and are discussed in this article can be categorized into prognostic scores, expenses scores and disease-specific scores. Since the introduction of compulsory recording of two scoring systems for accounting in the German diagnosis-related groups (DRG) system, these tools have gained more importance for all intensive care physicians. Problems remain in the valid calculation of scores and interpretation of the results.

Cancer is the most deadly disease that causes the serious health problems, physical disabilities, mortalities, and morbidities around the world. It is the second leading cause of death all over the world. Although great advancement have been made in the treatment of cancer progression, still significant deficiencies and room for improvement remain. Chemotherapy produced a number of undesired and toxic side effects. Natural therapies, such as the use of plant-derived products in the treatment of cancer, may reduce adverse and toxic side effects. However, many plants exist that have shown very promising anticancer activities in vitro and in vivo but their active anticancer principle have yet to be evaluated. Combined efforts of botanist, pharmacologist and chemists are required to find new lead anticancer constituent to fight disease. This review will help researchers in the finding of new bioactive molecules as it will focus on various plants evaluated for anticancer properties in vitro and in vivo.

Enforcer, manager or leader? The judicial role in family violence courts.

PubMed

King, Michael; Batagol, Becky

2010-01-01

Judicial supervision of offenders is an important component of many family violence courts. Skepticism concerning the ability of offenders to reform and a desire to protect victims has led to some judges to use supervision as a form of deterrence. Supervision is also used to hold offenders accountable for following court orders. Some family violence courts apply processes used in drug courts, such as rewards and sanctions, to promote offender rehabilitation. This article suggests that while protection and support of victims should be the prime concern of family violence courts, a form of judging that engages offenders in the development and implementation of solutions for their problems and supports their implementation is more likely to promote their positive behavioral change than other approaches to judicial supervision. The approach to judging proposed in this article draws from therapeutic jurisprudence, feminist theory, transformational leadership and solution-focused brief therapy principles.

Background The requirement that animals be used in research and testing in order to protect humans was formalized in the Nuremberg Code and subsequent national and international laws, codes, and declarations. Discussion We review the history of these requirements and contrast what was known via science about animal models then with what is known now. We further analyze the predictive value of animal models when used as test subjects for human response to drugs and disease. We explore the use of animals for models in toxicity testing as an example of the problem with using animal models. Summary We conclude that the requirements for animal testing found in the Nuremberg Code were based on scientifically outdated principles, compromised by people with a vested interest in animal experimentation, serve no useful function, increase the cost of drug development, and prevent otherwise safe and efficacious drugs and therapies from being implemented.

Genetically modified (GM) foods are the product of one of the most progressive fields of science-biotechnology. There are major concerns about GM foods in the public; some of them are reasonable, some of them are not. Biomedical risks of GM foods include problems regarding the potential allergenicity, horizontal gene transfer, but environmental side effects on biodiversity must also be recognized. Numerous methods have been developed to assess the potential risk of every GM food type. Benefits of the first generation of GM foods were oriented towards the production process and companies, the second generation of GM foods offers, on contrary, various advantages and added value for the consumer. This includes improved nutritional composition or even therapeutic effects. Recombinant probiotics and the principle of alternative gene therapy represent the latest approach of using GM organisms for biomedical applications. This article tries to summarize and to explain the problematic topic of GM food.

On different types of uncertainties in the context of the precautionary principle.

PubMed

Aven, Terje

2011-10-01

Few policies for risk management have created more controversy than the precautionary principle. A main problem is the extreme number of different definitions and interpretations. Almost all definitions of the precautionary principle identify "scientific uncertainties" as the trigger or criterion for its invocation; however, the meaning of this concept is not clear. For applying the precautionary principle it is not sufficient that the threats or hazards are uncertain. A stronger requirement is needed. This article provides an in-depth analysis of this issue. We question how the scientific uncertainties are linked to the interpretation of the probability concept, expected values, the results from probabilistic risk assessments, the common distinction between aleatory uncertainties and epistemic uncertainties, and the problem of establishing an accurate prediction model (cause-effect relationship). A new classification structure is suggested to define what scientific uncertainties mean. © 2011 Society for Risk Analysis.

Uncertainty principles for inverse source problems for electromagnetic and elastic waves

NASA Astrophysics Data System (ADS)

Griesmaier, Roland; Sylvester, John

2018-06-01

In isotropic homogeneous media, far fields of time-harmonic electromagnetic waves radiated by compactly supported volume currents, and elastic waves radiated by compactly supported body force densities can be modelled in very similar fashions. Both are projected restricted Fourier transforms of vector-valued source terms. In this work we generalize two types of uncertainty principles recently developed for far fields of scalar-valued time-harmonic waves in Griesmaier and Sylvester (2017 SIAM J. Appl. Math. 77 154–80) to this vector-valued setting. These uncertainty principles yield stability criteria and algorithms for splitting far fields radiated by collections of well-separated sources into the far fields radiated by individual source components, and for the restoration of missing data segments. We discuss proper regularization strategies for these inverse problems, provide stability estimates based on the new uncertainty principles, and comment on reconstruction schemes. A numerical example illustrates our theoretical findings.

The ultra high vacuum test and evaluation system for the preparation of negative electron affinity (NEA) photocathode has the characteristics of complex structure and powerful functions. Segmentation principle, advance function principle, curved surface principle, dynamic characteristics principle and nested principle adopted by the design of ultra high vacuum test and evaluation system for cathode preparation were analyzed. The applications of the physical contradiction and the substance-field analysis method of the theory of TRIZ in the cathode preparation ultra high vacuum test and evaluation system were discussed.

Surface-admittance equivalence principle for nonradiating and cloaking problems

NASA Astrophysics Data System (ADS)

Labate, Giuseppe; Alù, Andrea; Matekovits, Ladislau

2017-06-01

In this paper, we address nonradiating and cloaking problems exploiting the surface equivalence principle, by imposing at any arbitrary boundary the control of the admittance discontinuity between the overall object (with or without cloak) and the background. After a rigorous demonstration, we apply this model to a nonradiating problem, appealing for anapole modes and metamolecules modeling, and to a cloaking problem, appealing for non-Foster metasurface design. A straightforward analytical condition is obtained for controlling the scattering of a dielectric object over a surface boundary of interest. Previous quasistatic results are confirmed and a general closed-form solution beyond the subwavelength regime is provided. In addition, this formulation can be extended to other wave phenomena once the proper admittance function is defined (thermal, acoustics, elastomechanics, etc.).

Trampoline therapy is a useful part of the medical rehabilitation treatment of brain-injured children and adolescents, if the basic principles of accident prevention are observed. The therapy should only consist of systematically organised exercise series and be carried out by adequately trained sport teachers, medical paedagogues or physical therapists. In the "Jugendwerk Gailingen" an improvement of the standing balance and movement co-ordination was achieved in more than 20 patients with hemiparesis and tetraparesis. Only little progress was achieved in atactic and athetoid patients. It is important to stress the positive psychological effects of the trampoline therapy.

Roy's safety-first portfolio principle in financial risk management of disastrous events.

PubMed

Chiu, Mei Choi; Wong, Hoi Ying; Li, Duan

2012-11-01

Roy pioneers the concept and practice of risk management of disastrous events via his safety-first principle for portfolio selection. More specifically, his safety-first principle advocates an optimal portfolio strategy generated from minimizing the disaster probability, while subject to the budget constraint and the mean constraint that the expected final wealth is not less than a preselected disaster level. This article studies the dynamic safety-first principle in continuous time and its application in asset and liability management. We reveal that the distortion resulting from dropping the mean constraint, as a common practice to approximate the original Roy's setting, either leads to a trivial case or changes the problem nature completely to a target-reaching problem, which produces a highly leveraged trading strategy. Recognizing the ill-posed nature of the corresponding Lagrangian method when retaining the mean constraint, we invoke a wisdom observed from a limited funding-level regulation of pension funds and modify the original safety-first formulation accordingly by imposing an upper bound on the funding level. This model revision enables us to solve completely the safety-first asset-liability problem by a martingale approach and to derive an optimal policy that follows faithfully the spirit of the safety-first principle and demonstrates a prominent nature of fighting for the best and preventing disaster from happening. © 2012 Society for Risk Analysis.

Kim, Ungsoo Samuel; Park, Subin; Yoo, Hee Jeong; Hwang, Jeong-Min

2013-01-01

To evaluate the psychosocial distress of part-time occlusion therapy in intermittent exotropia. A total of 25 children (15 males and 10 females, aged 3 to 7 years, mean age 4.7 years) with intermittent exotropia were enrolled. Behavioral and psychosocial problems were assessed by the Korean Child Behavior Checklist (K-CBCL), which consists of eight categories of withdrawal, somatic problems, depression/anxiety, social problems, thought problems, attention problems, delinquent behavior, and aggressive behavior, and the Amblyopia Treatment Index (ATI). The ATI was designed to evaluate the three factors of compliance, adverse effect, and social stigma. The Parenting Stress Index (PSI) is a parent self-report designed to identify potentially dysfunctional parent-child systems. The K-CBCL was obtained before and after occlusion therapy, and the ATI and PSI were taken from parents only after occlusion therapy. We evaluated the change on the K-CBCL and the correlation between the K-CBCL and ATI. The attention problem assessed by the K-CBCL significantly decreased after occlusion therapy. On the ATI, the social stigma was relatively lower than compliance and adverse effect factors (Likert scale 2.64, 3.11, and 3.11, respectively). The somatic problem assessed by the K-CBCL and compliance on the ATI were significantly correlated (p = 0.014). There was no significant change in percentile scores of each subscale (parental dominant scale and child dominant scale) of the PSI. Total stress index before and after occlusion therapy was 97.16 ± 8.38 and 97.00 ± 8.16 respectively (p = 0.382). Occlusion therapy may influence the psychosocial impact on intermittent exotropia patients. Part-time occlusion significantly decreased the attention problem in children with intermittent strabismus. Children with a high somatic problem score on the KCBCL showed poor compliance to the part-time occlusion.

Itch Management: General Principles.

PubMed

Misery, Laurent

2016-01-01

Like pain, itch is a challenging condition that needs to be managed. Within this setting, the first principle of itch management is to get an appropriate diagnosis to perform an etiology-oriented therapy. In several cases it is not possible to treat the cause, the etiology is undetermined, there are several causes, or the etiological treatment is not effective enough to alleviate itch completely. This is also why there is need for symptomatic treatment. In all patients, psychological support and associated pragmatic measures might be helpful. General principles and guidelines are required, yet patient-centered individual care remains fundamental. © 2016 S. Karger AG, Basel.

Coaching Family Caregivers to Become Better Problem Solvers When Caring for Persons with Advanced Cancer.

PubMed

Dionne-Odom, J Nicholas; Lyons, Kathleen D; Akyar, Imatullah; Bakitas, Marie A

2016-01-01

Family caregivers of persons with advanced cancer often take on responsibilities that present daunting and complex problems. Serious problems that go unresolved may be burdensome and result in negative outcomes for caregivers' psychological and physical health and affect the quality of care delivered to the care recipients with cancer, especially at the end of life. Formal problem-solving training approaches have been developed over the past several decades to assist individuals with managing problems faced in daily life. Several of these problem-solving principles and techniques were incorporated into ENABLE (Educate, Nurture, Advise, Before Life End), an "early" palliative care telehealth intervention for individuals diagnosed with advanced cancer and their family caregivers. A hypothetical case resembling the situations of actual caregiver participants in ENABLE that exemplifies the complex problems that caregivers face is presented, followed by presentation of an overview of ENABLE's problem-solving key principles, techniques, and steps in problem-solving support. Though more research is needed to formally test the use of problem-solving support in social work practice, social workers can easily incorporate these techniques into everyday practice.

Detection of EPO gene doping in blood.

2012-11-01

Gene doping--or the abuse of gene therapy--will continue to threaten the sports world. History has shown that progress in medical research is likely to be abused in order to enhance human performance. In this review, we critically discuss the progress and the risks associated with the field of erythropoietin (EPO) gene therapy and its applicability to EPO gene doping. We present typical vector systems that are employed in ex vivo and in vivo gene therapy trials. Due to associated risks, gene doping is not a feasible alternative to conventional EPO or blood doping at this time. Nevertheless, it is well described that about half of the elite athlete population is in principle willing to risk its health to gain a competitive advantage. This includes the use of technologies that lack safety approval. Sophisticated detection approaches are a prerequisite for prevention of unapproved and uncontrolled use of gene therapy technology. In this review, we present current detection approaches for EPO gene doping, with a focus on blood-based direct and indirect approaches. Gene doping is detectable in principle, and recent DNA-based detection strategies enable long-term detection of transgenic DNA (tDNA) following in vivo gene transfer.

What are the core ideas behind the Precautionary Principle?

PubMed

Persson, Erik

2016-07-01

The Precautionary Principle is both celebrated and criticized. It has become an important principle for decision making, but it is also subject to criticism. One problem that is often pointed out with the principle is that is not clear what it actually says and how to use it. I have taken on this problem by performing an analysis of some of the most influential formulations of the principle in an attempt to identify the core ideas behind it, with the purpose of producing a formulation of the principle that is clear and practically applicable. It was found that what is called the Precautionary Principle is not a principle that tells us what do to achieve extra precaution or how to handle situations when extra precaution is called for. Instead, it was found to be a list of circumstances that each justify extra precaution. An analysis of some of the most common and influential formulations of the Precautionary Principle identified four such circumstances: (1) When we deal with important values that tend to be systematically downplayed by traditional decision methods - such as human health and the environment. (2) When we suspect that the decision might lead to irreversible and severe consequences and the values at stake are also irreplaceable, (3) When timing is at least as important as being right. (4) When it is more important to avoid false negatives than false positives. This interpretation of the Precautionary Principle does not say anything about what kind of actions to take when extra precaution is called for, but it does provide a clear and practically useful list of circumstances that call for extra precaution and that is not subject to the most common objections to the Precautionary Principle.

Fundamental principles of an anti-VEGF treatment regimen: optimal application of intravitreal anti-vascular endothelial growth factor therapy of macular diseases.

PubMed

Lanzetta, Paolo; Loewenstein, Anat

2017-07-01

Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is now considered the gold standard for the treatment of various retinal disorders. As therapy has evolved, so too have the treatment regimens employed by physicians in clinical practice; however, visual outcomes observed in the real world have typically not reflected those reported in clinical trials. Possible reasons for this include a lack of consensus on treatment regimens and a lack of clarity about what the aims of treatment should be. The Vision Academy Steering Committee met to discuss the principles of an ideal treatment regimen, using evidence from the literature to substantiate each point. Literature searches were performed using the MEDLINE/PubMed database (cut-off date: March 2016) and restricted to English-language publications. Studies with fewer than ten patients were excluded from this review. The Steering Committee identified the following four key principles for the ideal treatment regimen for anti-VEGF management of retinal diseases: 1. Maximize and maintain visual acuity (VA) benefits for all patients 2. Decide when to treat next, rather than whether to treat now 3. Titrate the treatment intervals to match patients' needs 4. Treat at each monitoring visit. It is proposed that the adoption of a proactive and more personalized approach in the clinic such as a treat-and-extend regimen will lead to benefits for both the patient and the physician, through a reduction in the associated treatment burden and better utilization of clinic resources. Implementation of the four principles should also lead to better VA outcomes for each patient, with a minimized risk of vision loss.

Incremental analysis of large elastic deformation of a rotating cylinder

NASA Technical Reports Server (NTRS)

Buchanan, G. R.

1976-01-01

The effect of finite deformation upon a rotating, orthotropic cylinder was investigated using a general incremental theory. The incremental equations of motion are developed using the variational principle. The governing equations are derived using the principle of virtual work for a body with initial stress. The governing equations are reduced to those for the title problem and a numerical solution is obtained using finite difference approximations. Since the problem is defined in terms of one independent space coordinate, the finite difference grid can be modified as the incremental deformation occurs without serious numerical difficulties. The nonlinear problem is solved incrementally by totaling a series of linear solutions.

The diagnostic evidence on clinical diseases and theoretic basis of moving cupping therapy were ex- plored in the paper. By the observation of the local reaction, such as skin appearance and color, the affected location, duration of sickness and nature of disease were judged. Different moving cupping methods were selected for different disorders. It was discovered that the property of syndromes should be recognized by the palpation on skin and muscle in the moving cupping therapy so that the pathogenesis and treating principle could be carefully determined. The moving cupping therapy is the important component of body surface therapy. Skin reaction observation and syndrome differentiation is the essential guidance of the moving cupping therapy.

Clinical holistic medicine: factors influencing the therapeutic decision-making. From academic knowledge to emotional intelligence and spiritual "crazy" wisdom.

PubMed

Ventegodt, Søren; Kandel, Isack; Merrick, Joav

2007-12-10

Scientific holistic medicine is built on holistic medical theory, on therapeutic and ethical principles. The rationale is that the therapist can take the patient into a state of salutogenesis, or existential healing, using his skills and knowledge. But how ever much we want to make therapy a science it remains partly an art, and the more developed the therapist becomes, the more of his/her decisions will be based on intuition, feeling and even inspiration that is more based on love and human concern and other spiritual motivations than on mental reason and rationality in a simple sense of the word. The provocative and paradoxal medieval western concept of the "truth telling clown", or the eastern concepts of "crazy wisdom" and "holy madness" seems highly relevant here. The problem is how we can ethically justify this kind of highly "irrational" therapeutic behavior in the rational setting of a medical institution. We argue here that holistic therapy has a very high success rate and is doing no harm to the patient, and encourage therapists, psychiatrists, psychologist and other academically trained "helpers" to constantly measure their own success-rate. This paper discusses many of the important factors that influence clinical holistic decision-making. Sexuality could, as many psychoanalysts from Freud to Reich and Searles have believed, be the most healing power that exists and also the most difficult for the mind to comprehend, and thus the most "crazy-wise" tool of therapy.

To prepare practitioners and researchers who are well equipped to deal with the inevitable myriad changes in health care and in society coming in the 21st century, a new focus is needed in occupational therapy education. In addition to proficiency in clinical skills and technical knowledge, occupational therapy graduates will need outcome competencies underlying the skills of critical reflection. In this article, the author presents (a) the rationale for the need for change in occupational therapy education, (b) key concepts of clinical reasoning and critical reflection pertaining to the outcome such change in occupational therapy education should address, (c) problem-based learning as a process and educational method to prepare occupational therapists in these competencies, and (d) the experience of the Program in Occupational Therapy at Shenandoah University in Winchester, Virginia, in implementing a problem-based learning curriculum.

To evaluate the relative efficacies of trauma-focused cognitive behavior therapy and problem-solving therapy in treating post-traumatic stress disorder in children affected by civil conflict in Aceh, Indonesia. A controlled trial of children with post-traumatic stress disorder ( N = 64) randomized children to either five individual weekly sessions of trauma-focused cognitive behavior therapy or problem-solving therapy provided by lay-counselors who were provided with brief training. Children were assessed by blind independent assessors at pretreatment, posttreatment and 3-month follow-up on post-traumatic stress disorder, depression and anger, as well as caregiver ratings of the child's post-traumatic stress disorder levels. Intent-to-treat analyses indicated no significant linear time × treatment condition interaction effects for post-traumatic stress disorder at follow-up ( t(129.05) = -0.55, p = 0.58), indicating the two conditions did not differ. Across both conditions, there were significant reductions in post-traumatic stress disorder on self-reported ( t(131.26) = -9.26, p < 0.001) and caregiver-reported ( t(170.65) = 3.53, p = 0.001) measures and anger ( t(127.66) = -7.14, p < 0.001). Across both conditions, there was a large effect size for self-reported post-traumatic stress disorder (cognitive behavior therapy: 3.73, 95% confidence interval = [2.75, 3.97]; problem-solving: 2.68, 95% confidence interval = [2.07, 3.29]). These findings suggest that trauma-focused cognitive behavior therapy and problem-solving approaches are comparably successful in reducing post-traumatic stress disorder and anger in treating mental health in children in a post-conflict setting. This pattern may reflect the benefits of non-specific therapy effects or gains associated with trauma-focused or problem-solving approaches.

How not to criticize the precautionary principle.

PubMed

Hughes, Jonathan

2006-10-01

The precautionary principle has its origins in debates about environmental policy, but is increasingly invoked in bioethical contexts. John Harris and Søren Holm argue that the principle should be rejected as incoherent, irrational, and representing a fundamental threat to scientific advance and technological progress. This article argues that while there are problems with standard formulations of the principle, Harris and Holm's rejection of all its forms is mistaken. In particular, they focus on strong versions of the principle and fail to recognize that weaker forms, which may escape their criticisms, are both possible and advocated in the literature.

Applying behavior analysis to school violence and discipline problems: Schoolwide positive behavior support

PubMed Central

Anderson, Cynthia M.; Kincaid, Donald

2005-01-01

School discipline is a growing concern in the United States. Educators frequently are faced with discipline problems ranging from infrequent but extreme problems (e.g., shootings) to less severe problems that occur at high frequency (e.g., bullying, insubordination, tardiness, and fighting). Unfortunately, teachers report feeling ill prepared to deal effectively with discipline problems in schools. Further, research suggests that many commonly used strategies, such as suspension, expulsion, and other reactive strategies, are not effective for ameliorating discipline problems and may, in fact, make the situation worse. The principles and technology of behavior analysis have been demonstrated to be extremely effective for decreasing problem behavior and increasing social skills exhibited by school children. Recently, these principles and techniques have been applied at the level of the entire school, in a movement termed schoolwide positive behavior support. In this paper we review the tenets of schoolwide positive behavior support, demonstrating the relation between this technology and applied behavior analysis. PMID:22478439

Bacterial meningitis - principles of antimicrobial treatment.

PubMed

Jawień, Miroslaw; Garlicki, Aleksander M

2013-01-01

Bacterial meningitis is associated with significant morbidity and mortality despite the availability of effective antimicrobial therapy. The management approach to patients with suspected or proven bacterial meningitis includes emergent cerebrospinal fluid analysis and initiation of appropriate antimicrobial and adjunctive therapies. The choice of empirical antimicrobial therapy is based on the patient's age and underlying disease status; once the infecting pathogen is isolated, antimicrobial therapy can be modified for optimal treatment. Successful treatment of bacterial meningitis requires the knowledge on epidemiology including prevalence of antimicrobial resistant pathogens, pathogenesis of meningitis, pharmacokinetics and pharmacodynamics of antimicrobial agents. The emergence of antibiotic-resistant bacterial strains in recent years has necessitated the development of new strategies for empiric antimicrobial therapy for bacterial meningitis.

1998-02-01

Qualitative methods appear increasingly in vogue in health services research (HSR). Such research, however, has utilized, often uncritically, a 'cookbook' of methods for data collection, and common-sense principles for data analysis. This paper argues that qualitative HSR benefits from recognizing and drawing upon theoretical principles underlying qualitative data collection and analysis. A distinction is drawn between problem-orientated and theory-orientated research, in order to illustrate how problem-orientated research would benefit from the introduction of theoretical perspectives in order to develop the knowledge base of health services research.

Rogal, Sonya M M; Snider, Paul D

2008-05-01

Problem based learning is a teaching and learning strategy that uses a problematic stimulus as a means of motivating and directing students to develop and acquire knowledge. Problem based learning is a strategy that is typically used with small groups attending a series of sessions. This article describes the principles of problem based learning and its application in atypical contexts; large groups attending discrete, stand-alone sessions. The principles of problem based learning are based on Socratic teaching, constructivism and group facilitation. To demonstrate the application of problem based learning in an atypical setting, this article focuses on the graduate nurse intake from a teaching hospital. The groups are relatively large and meet for single day sessions. The modified applications of problem based learning to meet the needs of atypical groups are described. This article contains a step by step guide of constructing a problem based learning package for large, single session groups. Nurse educators facing similar groups will find they can modify problem based learning to suit their teaching context.

Clinical and cost-effectiveness of computerised cognitive behavioural therapy for depression in primary care: Design of a randomised trial

PubMed Central

de Graaf, L Esther; Gerhards, Sylvia AH; Evers, Silvia MAA; Arntz, Arnoud; Riper, Heleen; Severens, Johan L; Widdershoven, Guy; Metsemakers, Job FM; Huibers, Marcus JH

2008-01-01

Background Major depression is a common mental health problem in the general population, associated with a substantial impact on quality of life and societal costs. However, many depressed patients in primary care do not receive the care they need. Reason for this is that pharmacotherapy is only effective in severely depressed patients and psychological treatments in primary care are scarce and costly. A more feasible treatment in primary care might be computerised cognitive behavioural therapy. This can be a self-help computer program based on the principles of cognitive behavioural therapy. Although previous studies suggest that computerised cognitive behavioural therapy is effective, more research is necessary. Therefore, the objective of the current study is to evaluate the (cost-) effectiveness of online computerised cognitive behavioural therapy for depression in primary care. Methods/Design In a randomised trial we will compare (a) computerised cognitive behavioural therapy with (b) treatment as usual by a GP, and (c) computerised cognitive behavioural therapy in combination with usual GP care. Three hundred mild to moderately depressed patients (aged 18–65) will be recruited in the general population by means of a large-scale Internet-based screening (N = 200,000). Patients will be randomly allocated to one of the three treatment groups. Primary outcome measure of the clinical evaluation is the severity of depression. Other outcomes include psychological distress, social functioning, and dysfunctional beliefs. The economic evaluation will be performed from a societal perspective, in which all costs will be related to clinical effectiveness and health-related quality of life. All outcome assessments will take place on the Internet at baseline, two, three, six, nine, and twelve months. Costs are measured on a monthly basis. A time horizon of one year will be used without long-term extrapolation of either costs or quality of life. Discussion Although computerised cognitive behavioural therapy is a promising treatment for depression in primary care, more research is needed. The effectiveness of online computerised cognitive behavioural therapy without support remains to be evaluated as well as the effects of computerised cognitive behavioural therapy in combination with usual GP care. Economic evaluation is also needed. Methodological strengths and weaknesses are discussed. Trial registration The study has been registered at the Netherlands Trial Register, part of the Dutch Cochrane Centre (ISRCTN47481236). PMID:18590518

Fluid therapy for children: facts, fashions and questions

2007-01-01

Fluid therapy restores circulation by expanding extracellular fluid. However, a dispute has arisen regarding the nature of intravenous therapy for acutely ill children following the development of acute hyponatraemia from overuse of hypotonic saline. The foundation on which correct maintenance fluid therapy is built is examined and the difference between maintenance fluid therapy and restoration or replenishment fluid therapy for reduction in extracellular fluid volume is delineated. Changing practices and the basic physiology of extracellular fluid are discussed. Some propose changing the definition of “maintenance therapy” and recommend isotonic saline be used as maintenance and restoration therapy in undefined amounts leading to excess intravenous sodium chloride intake. Intravenous fluid therapy for children with volume depletion should first restore extracellular volume with measured infusions of isotonic saline followed by defined, appropriate maintenance therapy to replace physiological losses according to principles established 50 years ago.

Drug targets in the cytokine universe for autoimmune disease.

Liu, Xuebin; Fang, Lei; Guo, Taylor B; Mei, Hongkang; Zhang, Jingwu Z

2013-03-01

In autoimmune disease, a network of diverse cytokines is produced in association with disease susceptibility to constitute the 'cytokine milieu' that drives chronic inflammation. It remains elusive how cytokines interact in such a complex network to sustain inflammation in autoimmune disease. This has presented huge challenges for successful drug discovery because it has been difficult to predict how individual cytokine-targeted therapy would work. Here, we combine the principles of Chinese Taoism philosophy and modern bioinformatics tools to dissect multiple layers of arbitrary cytokine interactions into discernible interfaces and connectivity maps to predict movements in the cytokine network. The key principles presented here have important implications in our understanding of cytokine interactions and development of effective cytokine-targeted therapies for autoimmune disorders.

BACKGROUND: Mental training considers sharing of mental health care information as the primary objective. The secondary objectives include facilitating dialogue about feelings such as isolation, sadness, labeling, loneliness and possible strategies for confronting with these feelings. Group therapy trainings have supportive functioning in accepting the environment so that the members are able to be part of the indigenous groups. However, no study has been ever done on the impact of this educational method on the communication problems of this group. This study aimed to determine the impact of group therapy training on the communication problems of Afghan immigrants. METHODS: This was a clinical trial study. Eighty-eight Afghan men were investigated. Sampling method was simple sampling method. Thereafter, the study subjects were divided randomly into two groups of test and control based on the inclusion criteria. Data collection tool was a self-made questionnaire about the social problems. For analyzing the data, software SPSS, independent t-test and paired t-test were used. RESULTS: Reviewing the data indicated lower mean score of the social problems after implementing the group therapy training in social communication compared with before implementing the group therapy training. Paired t-test showed a significant difference between mean scores of the social communication problems before and after the implementation of group therapy training. CONCLUSIONS: Given the effectiveness of the intervention, group therapy training on social problems in social communication of Afghan immigrants is recommended. This program should be part of continuous education and training of the Afghan immigrants. PMID:22224098

Cognition of an expert tackling an unfamiliar conceptual physics problem

Schuster, David; Undreiu, Adriana

2009-11-01

We have investigated and analyzed the cognition of an expert tackling a qualitative conceptual physics problem of an unfamiliar type. Our goal was to elucidate the detailed cognitive processes and knowledge elements involved, irrespective of final solution form, and consider implications for instruction. The basic but non-trivial problem was to find qualitatively the direction of acceleration of a pendulum bob at various stages of its motion, a problem originally studied by Reif and Allen. Methodology included interviews, introspection, retrospection and self-reported metacognition. Multiple facets of cognition were revealed, with different reasoning strategies used at different stages and for different points on the path. An account is given of the zigzag thinking paths and interplay of reasoning modes and schema elements involved. We interpret the cognitive processes in terms of theoretical concepts that emerged, namely: case-based, principle-based, experiential-intuitive and practical-heuristic reasoning; knowledge elements and schemata; activation; metacognition and epistemic framing. The complexity of cognition revealed in this case study contrasts with the tidy principle-based solutions we present to students. The pervasive role of schemata, case-based reasoning, practical heuristic strategies, and their interplay with physics principles is noteworthy, since these aspects of cognition are generally neither recognized nor taught. The schema/reasoning-mode perspective has direct application in science teaching, learning and problem-solving.

Errors Analysis of Students in Mathematics Department to Learn Plane Geometry

2018-04-01

This article describes the results of qualitative descriptive research that reveal the locations, types and causes of student error in answering the problem of plane geometry at the problem-solving level. Answers from 59 students on three test items informed that students showed errors ranging from understanding the concepts and principles of geometry itself to the error in applying it to problem solving. Their type of error consists of concept errors, principle errors and operational errors. The results of reflection with four subjects reveal the causes of the error are: 1) student learning motivation is very low, 2) in high school learning experience, geometry has been seen as unimportant, 3) the students' experience using their reasoning in solving the problem is very less, and 4) students' reasoning ability is still very low.

SU-E-T-191: First Principle Calculation of Quantum Yield in Photodynamic Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Abolfath, R; Guo, F; Chen, Z

Purpose: We present a first-principle method to calculate the spin transfer efficiency in oxygen induced by any photon fields especially in MeV energy range. The optical pumping is mediated through photosensitizers, e.g., porphyrin and/or ensemble of quantum dots. Methods: Under normal conditions, oxygen molecules are in the relatively non-reactive triplet state. In the presence of certain photosensitizer compounds such as porphyrins, electromagnetic radiation of specific wavelengths can excite oxygen to highly reactive singlet state. With selective uptake of photosensitizers by certain malignant cells, photon irradiation of phosensitized tumors can lead to selective killing of cancer cells. This is the basismore » of photodynamic therapy (PDT). Despite several attempts, PDT has not been clinically successful except in limited superficial cancers. Many parameters such as photon energy, conjugation with quantum dots etc. can be potentially combined with PDT in order to extend the role of PDT in cancer management. The key quantity for this optimization is the spin transfer efficiency in oxygen by any photon field. The first principle calculation model presented here, is an attempt to fill this need. We employ stochastic density matrix description of the quantum jumps and the rate equation methods in quantum optics based on Markov/Poisson processes and calculate time evolution of the population of the optically pumped singlet oxygen. Results: The results demonstrate the feasibility of our model in showing the dependence of the optical yield in generating spin-singlet oxygen on the experimental conditions. The adjustable variables can be tuned to maximize the population of the singlet oxygen hence the efficacy of the photodynamic therapy. Conclusion: The present model can be employed to fit and analyze the experimental data and possibly to assist researchers in optimizing the experimental conditions in photodynamic therapy.« less

A novel adaptive mixed reality system for stroke rehabilitation: principles, proof of concept, and preliminary application in 2 patients.

PubMed

Chen, Yinpeng; Duff, Margaret; Lehrer, Nicole; Liu, Sheng-Min; Blake, Paul; Wolf, Steven L; Sundaram, Hari; Rikakis, Thanassis

2011-01-01

This article presents the principles of an adaptive mixed reality rehabilitation (AMRR) system, as well as the training process and results from 2 stroke survivors who received AMRR therapy, to illustrate how the system can be used in the clinic. The AMRR system integrates traditional rehabilitation practices with state-of-the-art computational and motion capture technologies to create an engaging environment to train reaching movements. The system provides real-time, intuitive, and integrated audio and visual feedback (based on detailed kinematic data) representative of goal accomplishment, activity performance, and body function during a reaching task. The AMRR system also provides a quantitative kinematic evaluation that measures the deviation of the stroke survivor's movement from an idealized, unimpaired movement. The therapist, using the quantitative measure and knowledge and observations, can adapt the feedback and physical environment of the AMRR system throughout therapy to address each participant's individual impairments and progress. Individualized training plans, kinematic improvements measured over the entire therapy period, and the changes in relevant clinical scales and kinematic movement attributes before and after the month-long therapy are presented for 2 participants. The substantial improvements made by both participants after AMRR therapy demonstrate that this system has the potential to considerably enhance the recovery of stroke survivors with varying impairments for both kinematic improvements and functional ability.

Primary care and addiction treatment: lessons learned from building bridges across traditions.

PubMed

Stanley, A H

1999-01-01

A primary care unit combined with residential addiction treatment allows patients with addictive disease and chronic medical or psychiatric problems to successfully complete the treatment. These are patients who would otherwise fail treatment or fail to be considered candidates for treatment. Health care providers should have a background in primary care and have the potential to respond professionally to clinical problems in behavioral medicine. Ongoing professional training and statistical quality management principles can maintain morale and productivity. Health education is an integral part of primary care. The costs of such concurrent care when viewed in the context of the high societal and economic costs of untreated addictive disease and untreated chronic medical problems are low. The principles used to develop this primary care unit can be used to develop health care units for other underserved populations. These principles include identification of specific health care priorities and continuity of rapport with the target population and with addiction treatment staff.

Proportionality, just war theory and weapons innovation.

PubMed

Forge, John

2009-03-01

Just wars are supposed to be proportional responses to aggression: the costs of war must not greatly exceed the benefits. This proportionality principle raises a corresponding 'interpretation problem': what are the costs and benefits of war, how are they to be determined, and a 'measurement problem': how are costs and benefits to be balanced? And it raises a problem about scope: how far into the future do the states of affairs to be measured stretch? It is argued here that weapons innovation always introduces costs, and that these costs cannot be determined in advance of going to war. Three examples, the atomic bomb, the AK-47 and the ancient Greek catapult, are given as examples. It is therefore argued that the proportionality principle is inapplicable prospectively. Some replies to the argument are discussed and rejected. Some more general defences of the proportionality principle are considered and also rejected. Finally, the significance of the argument for Just War Theory as a whole is discussed.

The first part renders very synthetically a few of the principal pathogenetical mechanisms implicated in PA, as well as general data about MODS, and then tackles therapeutical principles of great organic disfunction, the therapy of septic states and nutrition in PA. Hemodynamics dysfunction--the therapeutical objectives are correlated with the principal mechanisms implicated in cardio-vascular disfunction (the grown level of some myocardial depressive factors, the shortcoming of peripheral vascular resistance, a.s.o.). The therapeutical principles covets the volemic restoration, inotropic therapy, the correction of hydro-ionic and acido-basic disorders, the vasomotor therapy, the CID's correction, the myocardium protection against the free radicals of oxygen. The therapy is recommended to be individualized depending on the clinical data and the monitoring of some parameters (T.A, P.V.C., intrapulmonary pressure, EKG, hematocrit value, a.s.o.). Pulmonary disfunction--includes the therapy of some clinical forms of pulmonary complications, the restrictive syndrome, infections, the pulmonary shunt, the atelectasis and insists on ARDS which is a complication with vital implications. The therapy of curdling disorders--recommends blood, derivatives, antiprotease, the substitution of the consumed curdling factors, as well as the removal of the pathogenic factors which disturb the coagulation-coagulolysis equilibrium. Purge proceedings--covet the elimination from the organism of the toxic agents which generate cell-organic lesions. That's why it is moot the elimination of the pancreatic toxins before reaching the circulation (the thoracic tube draining and peritoneal lavage) as well as extrarenal purge proceedings (hemodialysis, hemofiltration and hemodiafiltration) with their benefits and limits. The sepsis and the immunotherapy--are tackled based on recent data from literature which besides antibiotherapy insists on the neutralization of various toxins and mediators by means of monoclonal and polyclonal antibodies, anti TFL antibodies, IL, a.s.o. Nutrition--is different presented, parenterally and enterally, each of them with their benefits and limits and with the recommendation to be used by means of the clinical form. There are mentioned some other additional treatments (pain removing, antagonisms of H2 receptors, inflammation and cytotoxicity inhibition, gastric decompression, a.s.o.).

[Acceptance and mindfulness-based cognitive-behavioral therapies].

PubMed

Ngô, Thanh-Lan

2013-01-01

Cognitive behavioral therapy (CBT) is one of the main approaches in psychotherapy. It teaches the patient to examine the link between dysfunctional thoughts and maladaptive behaviors and to re- evaluate the cognitive biases involved in the maintenance of symptoms by using strategies such as guided discovery. CBT is constantly evolving in part to improve its' effectiveness and accessibility. Thus in the last decade, increasingly popular approaches based on mindfulness and acceptance have emerged. These therapies do not attempt to modify cognitions even when they are biased and dysfunctional but rather seek a change in the relationship between the individual and the symptoms. This article aims to present the historical context that has allowed the emergence of this trend, the points of convergence and divergence with traditional CBT as well as a brief presentation of the different therapies based on mindfulness meditation and acceptance. Hayes (2004) described three successive waves in behavior therapy, each characterized by "dominant assumptions, methods and goals": traditional behavior therapy, cognitive therapy and therapies based on mindfulness meditation and acceptance. The latter consider that human suffering occurs when the individual lives a restricted life in order avoid pain and immediate discomfort to the detriment of his global wellbeing. These therapies combine mindfulness, experiential, acceptance strategies with traditional behavior principles in order to attain lasting results. There are significant points of convergence between traditional CBT and therapies based on mindfulness meditation and acceptance. They are both empirically validated, based upon a theoretical model postulating that avoidance is key in the maintenance of psychopathology and they recommend an approach strategy in order to overcome the identified problem. They both use behavioral techniques in the context of a collaborative relationship in order to identify precise problems and to achieve specific goals. They focus on the present moment rather than on historical causes. However, they also present significant differences: control vs acceptance of thoughts, focus on cognition vs behavior, focus on the relationship between the individual and his thoughts vs cognitive content, goal of modifying dysfunctional beliefs vs metacognitive processes, use of experiential vs didactic methods, focus on symptoms vs quality of life, strategies used before vs after the unfolding of full emotional response. The main interventions based on mindfulness meditation and acceptance are: Acceptance and Commitment Therapy, Functional Analytic Therapy, the expanded model of Behavioral Activation, Metacognitive Therapy, Mindfulness based Cognitive Therapy, Dialectic Behavior Therapy, Integrative Behavioral Couples Therapy and Compassionate Mind Training. These are described in this article. They offer concepts and techniques which might enhance therapeutic efficacy. They teach a new way to deploy attention and to enter into a relationship with current experience (for example, defusion) in order to diminish cognitive reactivity, a maintenance factor for psychopathology, and to enhance psychological flexibility. The focus on cognitive process, metacognition as well as cognitive content might yield additional benefits in therapy. It is possible to combine traditional CBT with third wave approaches by using psychoeducation and cognitive restructuring in the beginning phases of therapy in order to establish thought bias and to then encourage acceptance of internal experiences as well as exposure to feared stimuli rather than to continue to use cognitive restructuring techniques. Traditional CBT and third wave approaches seem to impact different processes: the former enhance the capacity to observe and describe experiences and the latter diminish experiential avoidance and increase conscious action as well as acceptance. The identification of personal values helps to motivate the individual to undertake actions required in order to enhance quality of life. In the case of chronic illness, it diminishes suffering by increasing acceptance. Although the evidence base supporting the efficacy of third wave approaches is less robust than in the case of traditional cognitive or behavior therapy, therapies based on mindfulness meditation and acceptance are promising interventions that might help to elucidate change process and offer complementary strategies in order to help patients.

2018-01-01

Stress is one of the world’s largest health problems, leading to exhaustion, burnout, anxiety, a weak immune system, or even organ damage. In Germany, stress-induced work absenteeism costs about 20 billion Euros per year. Therefore, it is not surprising that the Central Federal Association of the public Health Insurance Funds in Germany ascribes particular importance to stress prevention and stress management as well as health enhancing measures. Building on current integrative and embodied stress theories, Creative Arts Therapies (CATs) or arts interventions are an innovative way to prevent stress and improve stress management. CATs encompass art, music, dance/movement, and drama therapy as their four major modalities. In order to obtain an overview of CATs and arts interventions’ efficacy in the context of stress reduction and management, we conducted a systematic review with a search in the following data bases: Academic Search Complete, ERIC, Medline, Psyndex, PsycINFO and SocINDEX. Studies were included employing the PICOS principle and rated according to their evidence level. We included 37 studies, 73% of which were randomized controlled trials. 81.1% of the included studies reported a significant reduction of stress in the participants due to interventions of one of the four arts modalities.

Pharmacological management of acute radiation morbidity.

Zimmermann, J S; Kimmig, B

1998-11-01

The acute radiation morbidity may be a serious problem for the patient and may be decreased by pharmacological approaches. A database research (Medline, Cancerlit, DIMDI, etc.) was performed in order to obtain pharmacological approaches to decrease the acute radiation morbidity. The evaluation was focused on therapeutic principles but not on special drugs. Different approaches may be chosen to protect healthy tissues from the effects of ionizing radiation: 1. administration of cyto- or radioprotective agents prior to irradiation, 2. administration of agents to avoid additional secondary toxicity by inflammation or superinfection during the treatment cycle (supportive care) and 3. administration of rescue agents, such as bone marrow CSFs or hyperbaric oxygen (HBO), after therapy. For radioprotection, there are reports on cellular protection by vitamine E, vitamine C, beta carotene, ribose-cysteine, glutamine, Mgcl2/adenosine triphosphate and WR-2721 (amifostine). In general, preclinical studies show that the combination of pretreatment with amifostine, irradiation, and G-CSF after radiation enhances hematologic recovery. Assessment of these combined effects, including local supportive therapies, merits further clinical investigation. There are data from prospective studies as well as from empirical clinical experience, that radioprotection and clinical supportive care may reduce the treatment related morbidity by 10 to 30% either. A further improvement of the therapeutic ratio is to be expected by systemically combined application of radioprotectors, supportive care and rescue agents.

Described are the theoretical development and computer implementation of reliable and efficient methods for the analysis of coupled mechanical problems that involve the interaction of mechanical, thermal, phase-change and electromagnetic subproblems. The focus application has been the modeling of superconductivity and associated quantum-state phase-change phenomena. In support of this objective the work has addressed the following issues: (1) development of variational principles for finite elements, (2) finite element modeling of the electromagnetic problem, (3) coupling of thermal and mechanical effects, and (4) computer implementation and solution of the superconductivity transition problem. The main accomplishments have been: (1) the development of the theory of parametrized and gauged variational principles, (2) the application of those principled to the construction of electromagnetic, thermal and mechanical finite elements, and (3) the coupling of electromagnetic finite elements with thermal and superconducting effects, and (4) the first detailed finite element simulations of bulk superconductors, in particular the Meissner effect and the nature of the normal conducting boundary layer. The theoretical development is described in two volumes. This volume, Volume 1, describes mostly formulations for specific problems. Volume 2 describes generalization of those formulations.

Human Cognitive Limitations. Broad, Consistent, Clinical Application of Physiological Principles Will Require Decision Support.

PubMed

Morris, Alan H

2018-02-01

Our education system seems to fail to enable clinicians to broadly understand core physiological principles. The emphasis on reductionist science, including "omics" branches of research, has likely contributed to this decrease in understanding. Consequently, clinicians cannot be expected to consistently make clinical decisions linked to best physiological evidence. This is a large-scale problem with multiple determinants, within an even larger clinical decision problem: the failure of clinicians to consistently link their decisions to best evidence. Clinicians, like all human decision-makers, suffer from significant cognitive limitations. Detailed context-sensitive computer protocols can generate personalized medicine instructions that are well matched to individual patient needs over time and can partially resolve this problem.

González de Posada, Francisco

2004-01-01

The nowadays classical Anthropic Principle is put both in the historical perspective of the traditional problem of "the place of man in the Universe', and in the confluence of several scientific "border" issues, some of which, due to their problematical nature, are also subject of philosophical analysis. On the one hand, the scientific uses of the Principle, related to the initial and constitutional conditions of "our Universe", are enumerated, as they are supposedly necessary for the appearance and consequent development of Life--up to Man--. On the other, an organized collection of the principles of today's Physics is synthetically exhibited. The object of this work is to determine the intrinsic scientific nature of the Anthropic Principle, and the role it plays in the global frame of the principles of Physics (Astrophysics, Astrobiology and Cosmology).

2016-01-01

Family caregivers of persons with advanced cancer often take on responsibilities that present daunting and complex problems. Serious problems that go unresolved may be burdensome and result in negative outcomes for caregivers’ psychological and physical health and affect the quality of care delivered to the care recipients with cancer, especially at the end of life. Formal problem-solving training approaches have been developed over the past several decades to assist individuals with managing problems faced in daily life. Several of these problem-solving principles and techniques were incorporated into ENABLE (Educate, Nurture, Advise, Before Life End), an ‘early’ palliative care telehealth intervention for individuals diagnosed with advanced cancer and their family caregivers. A hypothetical case resembling the situations of actual caregiver participants in ENABLE that exemplifies the complex problems that caregivers face is presented followed by presentation of an overview of ENABLE’s problem-solving key principles, techniques and steps in problem-solving support. Though more research is needed to formally test the use of problem-solving support in social work practice, social workers can easily incorporate these techniques into everyday practice.

In this paper, we investigate a class of infinite-dimensional optimal control problems, where the state equation is given by a stochastic delay evolution equation with random coefficients, and the corresponding adjoint equation is given by an anticipated backward stochastic evolution equation. We first prove the continuous dependence theorems for stochastic delay evolution equations and anticipated backward stochastic evolution equations, and show the existence and uniqueness of solutions to anticipated backward stochastic evolution equations. Then we establish necessary and sufficient conditions for optimality of the control problem in the form of Pontryagin’s maximum principles. To illustrate the theoretical results, we applymore » stochastic maximum principles to study two examples, an infinite-dimensional linear-quadratic control problem with delay and an optimal control of a Dirichlet problem for a stochastic partial differential equation with delay. Further applications of the two examples to a Cauchy problem for a controlled linear stochastic partial differential equation and an optimal harvesting problem are also considered.« less

Proof of concept: performance testing in models.

Pharmacokinetic (PK) and pharmacodynamic (PD) principles that predict antimicrobial efficacy can be used to set targets for antimicrobial design and optimisation. Although current formulations of amoxicillin and amoxicillin/clavulanate have retained their efficacy against many, but not all, penicillin-nonsusceptible Streptococcus pneumoniae, additional coverage is required to address the growing problem of drug-resistant strains. Accordingly, two new oral formulations of amoxicillin/clavulanate, a paediatric formulation at 90/6.4 mg/kg/day and a pharmacokinetically enhanced formulation at 2000/125 mg twice daily for adults, were designed using PK/PD principles. These principles indicate that for amoxicillin and amoxicillin/clavulanate, a time above MIC of 35-40% of the dosing interval is predictive of high bacterial efficacy. In line with PK/PD predictions, simulation of human pharmacokinetics in in-vitro kinetic models and in a rat model of pneumonia, amoxicillin/clavulanate 2000/125 mg twice daily was highly effective against S. pneumoniae strains with amoxicillin MICs of 4 or 8 mg/L. Against strains with amoxicillin MICs of 4 mg/L, amoxicillin/clavulanate 2000/125 mg twice daily was significantly more effective than the conventional 875/125 mg twice daily formulation, azithromycin and levofloxacin, even though all levofloxacin MICs were < or = 1 mg/L. Following infection with S. pneumoniae strains with amoxicillin MICs of 8 mg/L, the amoxicillin/clavulanate 2000/125 mg twice daily formulation was more effective than the conventional amoxicillin/clavulanate formulations of 875/125 mg twice daily and three times daily and 1000/125 mg three times daily, and had similar or better efficacy than azithromycin and levofloxacin, depending on the strain. These data indicate the potential benefit of therapy with amoxicillin/clavulanate 2000/125 mg twice daily compared with conventional formulations and other marketed antimicrobials in the treatment of respiratory tract infection.

A feminist approach to family therapy.

PubMed

Hare-Mustin, R T

1978-06-01

Although family therapy recognizes the importance of the social context as a determiner of behavior, family therapists have not examined the consequences of traditional socialization practices that primarily disadvantage women. The unquestioned reinforcement of stereotyped sex roles takes place in much of family therapy. A feminist therapy orientation that considers the consequences of stereotyped sex roles and the statuses prescribed by society for females and males should be part of family therapy practice. This paper describes the ways in which family therapists who are aware of their own biases and those of the family can change sexist patterns through applying feminist principles to such areas as the contract, shifting tasks in the family, communication, generational boundaries, relabeling deviance, modeling, and therapeutic alliances.

2016-04-01

This article aims to promote awareness among primary care providers and support electroconvulsive therapy as a generally well-tolerated, effective therapeutic modality to treat specific psychiatric conditions in appropriately selected patients. There seem to be several potential barriers to treatment with electroconvulsive therapy including stigma, lack of providers who preform it, and lack of awareness among providers referring patients who may be appropriate candidates. The article provides a brief overview of electroconvulsive therapy principles and topics and includes a case report to illustrate clinical utility. The article proposes the concept that a potential way to overcome barriers to treatment with electroconvulsive therapy may be to promote education and awareness of it as a viable treatment modality among primary care providers. © The Author(s) 2016.

The echinocandins have a growing role in the treatment of fungal infections because of their novel mechanism of action. This is reflected in recently published management guidelines, but available in vitro data, animal studies, and clinical studies do not clearly differentiate the three agents in class. Comparative clinical efficacy among agents within the class, pharmacokinetic profiles in special populations, pharmacoeconomics justifications, and place in therapy have been largely unanswered. They share many common properties but marketing strategies of drug manufacturers are engaged in product differentiation. Although exist similarities in the pharmacokinetic (PK) profiles of the echinocandins, limited data have been published regarding their pharmacokinetics in continuous renal replacement therapy (CRRT) patients. The pharmacokinetics of drug removal in critically ill patients receiving CRRT is very complex, with multiple variables affecting clearance. This review outlines the basic principles that determine whether a dose adjustment is required. Two studies with data on PK parameters of micafungin and anidulafungin in CRRT patients have been published and are compared following that basic principles in the review.

2010-01-01

The present review of the literature data highlights modern approaches to and major trends in diagnostics and conservative treatment of lymphedema of the lower extremities based on the generalized world experience. Patients with lymphedema of the lower extremities comprise a "difficult to manage" group because the disease is characterized by steady progression and marked refractoriness to various conservative therapeutic modalities creating problems for both the patient and the attending physician. Modern methods for the diagnosis of lymphedema are discussed with special reference to noninvasive and minimally invasive techniques (such as lymphoscintiography, computed tomography, MRT, laser Doppler flowmetry, etc.). During the last 20 years, combined conservative therapy has been considered as the method of choice for the management of different stages and forms of lymphedema of the lower extremities in foreign clinics. The basis of conservative therapy is constituted by manual lymph drainage (MLD), compression bandages using short-stretch materials, physical exercises, and skin care (using the method of M. Foldi). Also reviewed are the main physiobalneotherapeutic methods traditionally widely applied for the treatment of lymphedema of the lower extremities in this country. Original methods for the same purpose developed by the authors are described including modifications of cryotherapy, pulsed matrix laserotherapy, hydro- and balneotherapy. Mechanisms of their therapeutic action on the main pathogenetic factors responsible for the development of lymphedema (with special reference to lymph transport and formation) are discussed. The principles of combined application of physiotherapeutic methods for the rehabilitative treatment of patients presenting with lymphedema of the lower extremities are briefly substantiated. Special emphasis is laid on their influence on major components of the pathological process.

Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) is a conjoint parent-child treatment developed by Cohen, Mannarino, and Deblinger that uses cognitive-behavioral principles and exposure techniques to prevent and treat posttraumatic stress, depression, and behavioral problems. This review defined TF-CBT, differentiated it from other models, and assessed the evidence base. Authors reviewed meta-analyses, reviews, and individual studies (1995 to 2013). Databases surveyed were PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, PILOTS, the ERIC, and the CINAHL. They chose from three levels of research evidence (high, moderate, and low) on the basis of benchmarks for number of studies and quality of their methodology. They also described the evidence of effectiveness. The level of evidence for TF-CBT was rated as high on the basis of ten RCTs, three of which were conducted independently (not by TF-CBT developers). TF-CBT has demonstrated positive outcomes in reducing symptoms of posttraumatic stress disorder, although it is less clear whether TF-CBT is effective in reducing behavior problems or symptoms of depression. Limitations of the studies include concerns about investigator bias and exclusion of vulnerable populations. TF-CBT is a viable treatment for reducing trauma-related symptoms among some children who have experienced trauma and their nonoffending caregivers. Based on this evidence, TF-CBT should be available as a covered service in health plans. Ongoing research is needed to further identify best practices for TF-CBT in various settings and with individuals from various racial and ethnic backgrounds and with varied trauma histories, symptoms, and stages of intellectual, social, and emotional development.

The traditional approach to solving patient safety problems in healthcare is to blame the last person to touch the patient. But since the publication of To Err is Human, the call has been instead to use human factors and systems engineering methods and principles to solve patient safety problems. However, an understanding of the human factors and systems engineering is lacking, and confusion remains about what it means to apply their principles. This paper provides a primer on them and their applications to patient safety.

X-ray absorption spectra (XAS) have been used to determine the absorption edges of atoms present in a sample under study. A series of small-angle X-ray scattering (SAXS) measurements using different monochromatic X-ray beams at different wavelengths near the absorption edges is performed to solve the Babinet principle problem. The sizes of clusters containing atoms determined by the method of XAS were defined in SAXS experiments. In contrast to differential X-ray porosimetry, anomalous SAXS makes it possible to determine sizes of clusters of different atomic compositions.

This paper is concerned with first order necessary optimality conditions for state constrained control problems in separable Banach spaces. Assuming inward pointing conditions on the constraint, we give a simple proof of Pontryagin maximum principle, relying on infinite dimensional neighboring feasible trajectories theorems proved in [20]. Further, we provide sufficient conditions guaranteeing normality of the maximum principle. We work in the abstract semigroup setting, but nevertheless we apply our results to several concrete models involving controlled PDEs. Pointwise state constraints (as positivity of the solutions) are allowed.

2012-05-01

Fibromyalgia is a chronic widespread pain disorder commonly associated with comorbid symptoms, including fatigue and nonrestorative sleep. As in the management of other chronic medical disorders, the approach for fibromyalgia management follows core principles of comprehensive assessment, education, goal setting, multimodal treatment including pharmacological (eg, pregabalin, duloxetine, milnacipran) and nonpharmacological therapies (eg, physical activity, behavioral therapy, sleep hygiene, education), and regular education and monitoring of treatment response and progress. Based on these core management principles, this review presents a framework for primary care providers through which they can develop a patient-centered treatment program for patients with fibromyalgia. This proactive and systematic treatment approach encourages ongoing education and patient self-management and is designed for use in the primary care setting.

2014-01-01

The fundamental basics of contact radiation therapy (brachytherapy) for gynecological cancer are presented. During brachytherapy the principles of conformal radiotherapy should be implemented, the aim of which is to sum the maximum possible dose of radiation to the tumor and decrease the dose load in adjacent organs and tissues, which allows reducing the frequency of radiation damage at treatment of primary tumors. It is really feasible only on modern technological level, thanks to precision topometry preparation, optimal computer dosimetrical and radiobiological planning of each session and radiotherapy in general. Successful local and long-term results of the contact radiation therapy for cancer of cervix and endometrium are due to optimal anatomical and topometrical ratio of the tumor localization, radioactive sources, and also physical and radiobiological laws of distribution and effects of ionizing radiation, the dose load accounting rules.

The fundamental goal of treating any stenosis is luminal enlargement to ameliorate the underlying obstructive symptoms. Symptoms depend on the etiology and the site of the stricture and may include dysphagia, nausea and vomiting, abdominal pain, obstipation, or frank bowel obstruction. This article compares the various current technologies available for the treatment of gastrointestinal stenoses with regard to ease and site of application, patient tolerance, safety and efficacy data, and cost-benefit ratio. Recent studies indicate that gastrointestinal dilation and stenting have evolved to a point at which in many if not most situations they can be the first line therapy and potentially the final therapy needed to treat the underlying condition. Following techniques and principles in the management of gastrointestinal strictures would allow for the well tolerated and effective treatment of most patients with the tools currently available today.

The Principle-Based Method of Practical Ethics.

PubMed

Spielthenner, Georg

2017-09-01

This paper is about the methodology of doing practical ethics. There is a variety of methods employed in ethics. One of them is the principle-based approach, which has an established place in ethical reasoning. In everyday life, we often judge the rightness and wrongness of actions by their conformity to principles, and the appeal to principles plays a significant role in practical ethics, too. In this paper, I try to provide a better understanding of the nature of principle-based reasoning. To accomplish this, I show in the first section that these principles can be applied to cases in a meaningful and sufficiently precise way. The second section discusses the question how relevant applying principles is to the resolution of ethical issues. This depends on their nature. I argue that the principles under consideration in this paper should be interpreted as presumptive principles and I conclude that although they cannot be expected to bear the weight of definitely resolving ethical problems, these principles can nevertheless play a considerable role in ethical research.

The dental erosion or decalcification of enamel is a significant clinical problem. Apple acidic beverages are thought to increase the potential for dental erosion. The purpose of this in vitro study was to investigate the effect of clove essential oil (CEO) and its active principles on tooth decalcification of apple juices. On GC-MS analysis, CEO showed a high content of eugenol (58.29%) and eugenyl acetate (19.10%). Teeth specimens were randomly divided into 5 treatment groups: control, CEO, eugenol, eugenyl-acetate, and fluoride. The specimens were exposed for 24 h and were analyzed for calcium contents using Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES). Data were analyzed using student t-test (P < 0.05). CEO, eugenol, and eugenyl-acetate significantly decreased the decalcification of tooth by the apple juice to only 17, 24, and 21 mgL−1, respectively. Hemolytic activity on human erythrocytes was studied to exclude the possibility of further associated cytotoxicity. It was observed that the CEO and its two lead molecules inhibit the decalcification and/or promote the remineralization caused by the apple juices. The effect of the test compounds appears to be distinct like that of fluoride treatment. CEO may, therefore, serve to be a promising adjunct to fluoride in the treatment of root caries during minimally invasive therapy. PMID:22997520

Nine key principles to guide youth mental health: development of service models in New South Wales.

PubMed

Howe, Deborah; Batchelor, Samantha; Coates, Dominiek; Cashman, Emma

2014-05-01

Historically, the Australian health system has failed to meet the needs of young people with mental health problems and mental illness. In 2006, New South Wales (NSW) Health allocated considerable funds to the reform agenda of mental health services in NSW to address this inadequacy. Children and Young People's Mental Health (CYPMH), a service that provides mental health care for young people aged 12-24 years, with moderate to severe mental health problems, was chosen to establish a prototype Youth Mental Health (YMH) Service Model for NSW. This paper describes nine key principles developed by CYPMH to guide the development of YMH Service Models in NSW. A literature review, numerous stakeholder consultations and consideration of clinical best practice were utilized to inform the development of the key principles. Subsequent to their development, the nine key principles were formally endorsed by the Mental Health Program Council to ensure consistency and monitor the progress of YMH services across NSW.

Smith, David; Pols, Rene; Lavis, Tiffany; Battersby, Malcolm; Harvey, Peter

2016-12-01

In South Australia (SA) problem gambling is mainly a result of the widespread availability of electronic gaming machines. A key treatment provider in SA offers free cognitive and behavioural therapy (CBT) to help-seeking problem gamblers. The CBT program focuses on the treatment of clients' urge to gamble using exposure therapy (ET) and cognitive therapy (CT) to restructure erroneous gambling beliefs. The aim of this study was to explore treatment specific and non-specific effects for CT alone and ET alone using qualitative interviews. Interviewees were a sub-sample of participants from a randomised trial that investigated the relative efficacy of CT versus ET. Findings revealed that all interviewees gained benefit from their respective therapies and their comments did not appear to favour one therapy over another. Both treatment specific and treatment non-specific effects were well supported as playing a therapeutic role to recovery. Participants' comments in both therapy groups suggested that symptom reduction was experienced on a gambling related urge-cognition continuum. In addition to symptom improvement from therapy-specific mechanisms, ET participants described a general acquisition of "rational thought" from their program of therapy and CT participants had "taken-over" their gambling urges. The findings also highlighted areas for further improvement including therapy drop-out.

2008-05-01

An explorative study was carried out to confirm Malaysian Physics teachers' perception that Archimedes' principle is a difficult topic for secondary level students. The interview method was used for data collection. The study sample was made of nine national secondary schools teachers from Miri, Sarawak. The data was analysed qualitatively using the Atlas-ti version 5.2 software. The findings of the study showed that i) Archimedes' principle as compared to Bernoulli's and Pascal's is the most difficult principle of hydrodynamics for students, ii) more time was given in the teaching and learning (TL) of Archimedes principle compared to the other two principles, iii) the major TL problems include conceptual understanding, application of physics principles and ideas, and lack of mathematical skills. These findings implicate the need to develop corresponding instructional materials and learning kits that can assist students' understanding of Archimedes' principle.

Parent-child interaction therapy is an effective means to prevent and correct children's mental problems. Interactive interventions shown to be effective share common features: the focus is on the support of the parent's sensitivity, positive guiding ability and reflective capability. Simultaneous participation of both parents in the therapy, application of video observation and affirmation of positive collaborative relationship with the parents seem to increase the efficacy of the intervention. The above-mentioned elements are utilized in an interactive therapy method called Theraplay.

Facilitating the use of implicit memory and learning in the physical therapy management of individuals with Alzheimer disease: a case series.

White, Laura; Ford, Matthew P; Brown, Cynthia J; Peel, Claire; Triebel, Kristen L

2014-01-01

Physical rehabilitation of individuals with Alzheimer disease (AD) is often complicated by impairments in explicit memory and learning. Rehabilitation strategies that facilitate the use of the preserved implicit memory system may be effective in treating patients with AD. The purpose of this case series is to describe the application of these strategies, including high-repetition practice, errorless learning (EL), and spaced retrieval, to the physical therapy management of individuals with moderate AD. Three women aged 89 to 95 years with moderate AD who resided in an assisted living facility participated in physical therapy to address their mobility limitations. Twelve physical therapy sessions were scheduled over a period of 4 weeks. Interventions were individually designed to address the mobility needs of each patient, and rehabilitation strategies based on implicit learning principles were integrated into the interventions. All patients participated in at least 10 of the 12 physical therapy sessions. Improvements in performance of objective measures of balance were observed in all patients, although only 1 patient's balance score exceeded the minimal detectable change. No significant clinical change was observed in any patients on the Timed Up and Go Test or self-selected gait speed. Principles of implicit learning were integrated into the interventions for these patients with moderate AD. However, the feasibility of applying the EL paradigm was limited. Further research on the effectiveness of EL, spaced retrieval, and other rehabilitation strategies that facilitate implicit learning of mobility skills in patients with AD is needed to promote optimal physical therapy outcomes in this patient population.

On Complex Water Conflicts: Role of Enabling Conditions for Pragmatic Resolution

NASA Astrophysics Data System (ADS)

Islam, S.; Choudhury, E.

2016-12-01

Many of our current and emerging water problems are interconnected and cross boundaries, domains, scales, and sectors. These boundary crossing water problems are neither static nor linear; but often are interconnected nonlinearly with other problems and feedback. The solution space for these complex problems - involving interdependent variables, processes, actors, and institutions - can't be pre-stated. We need to recognize the disconnect among values, interests, and tools as well as problems, policies, and politics. Scientific and technological solutions are desired for efficiency and reliability, but need to be politically feasible and actionable. Governing and managing complex water problems require difficult tradeoffs in exploring and sharing benefits and burdens through carefully crafted negotiation processes. The crafting of such negotiation process, we argue, constitutes a pragmatic approach to negotiation - one that is based on the identification of enabling conditions - as opposed to mechanistic casual explanations, and rooted in contextual conditions to specify and ensure the principles of equity and sustainability. We will use two case studies to demonstrate the efficacy of the proposed principled pragmatic approcah to address complex water problems.

The Adverse Effects of Le Châtelier's Principle on Teacher Understanding of Chemical Equilibrium

NASA Astrophysics Data System (ADS)

Cheung, Derek

2009-04-01

Although the scientific inadequacy of Le Châtelier's principle has long been documented in the literature, the principle is still treated as a central concept of chemical equilibrium by textbook writers and teachers in many countries. In the past, researchers' interest has focused on student misconceptions about chemical equilibrium and has neglected teacher misconceptions. This study aimed to determine how Le Châtelier's principle adversely affects teachers' ability to solve chemical equilibrium problems. This area of research is critically important because teachers cannot help their students understand what they themselves do not understand. In this study, a misconception test was developed and administered to a sample of 33 secondary chemistry teachers in Hong Kong. The test consisted of three open-ended chemical equilibrium questions. Analysis of teacher responses revealed that most of the 33 teachers failed the test as they relied on Le Châtelier's principle rather than the equilibrium law to tackle the three chemical equilibrium problems. Teachers' misconceptions about chemical equilibrium were categorized. Implications of these findings for chemistry teacher education and selection of curriculum content for school chemistry are discussed.

Quasi-static responses and variational principles in gradient plasticity

NASA Astrophysics Data System (ADS)

Nguyen, Quoc-Son

2016-12-01

Gradient models have been much discussed in the literature for the study of time-dependent or time-independent processes such as visco-plasticity, plasticity and damage. This paper is devoted to the theory of Standard Gradient Plasticity at small strain. A general and consistent mathematical description available for common time-independent behaviours is presented. Our attention is focussed on the derivation of general results such as the description of the governing equations for the global response and the derivation of related variational principles in terms of the energy and the dissipation potentials. It is shown that the quasi-static response under a loading path is a solution of an evolution variational inequality as in classical plasticity. The rate problem and the rate minimum principle are revisited. A time-discretization by the implicit scheme of the evolution equation leads to the increment problem. An increment of the response associated with a load increment is a solution of a variational inequality and satisfies also a minimum principle if the energy potential is convex. The increment minimum principle deals with stables solutions of the variational inequality. Some numerical methods are discussed in view of the numerical simulation of the quasi-static response.

Treatment of post-traumatic psychiatric disorders: A continuum of immediate, post-immediate and follow-up care mediated by specific psychotherapeutic principles. Clinical experience in French-speaking countries.

PubMed

Auxéméry, Yann

2018-06-07

People who witness a horrific event are at risk of suffering from acute psychological disorders, potentially leading to chronic post-traumatic symptoms and severe medico-psycho-social complications. Traumatised individuals suffer from psychological damage that is initially indescribable: they are often unable to ask for care in the immediate aftermath of an event. Afterwards, traumatic events and their post-traumatic consequences are still often hidden or minimised by patients for reasons linked to the disorder itself (inexpressibility, shame, depressive thoughts, fear of stigmatisation, etc.). The provision of the initial stage of care has a major impact on the long-term prognosis. Although official French recommendations remain vague, and scientific studies lack power, there is a developing professional consensus on practices, and developments in neurobiology are opening up new opportunities to validate them. Drawing upon our clinical experience and clinical principles provided by our mentors, our aim is to clarify the phases of psychotherapeutic treatment, and we describe three practices: immediate care ("defusing"), post-immediate care ("French debriefing" or "post-immediate psychotherapeutic intervention") and follow-up care ("deferred debriefing" and psychotherapy). Although the international literature considers these phases as separate, here we describe a continuity of talking therapies that support long-term remission. The effectiveness of the combination of immediate, post-immediate and follow-up care has been confirmed by events surrounding the recent Paris and Nice attacks. Specific psychotherapeutic principles are unrelated to a particular school of psychotherapy (notably cognitive and behavioural therapies, analytical therapies, various forms of hypnosis, and eye-movement therapies, etc.). Instead, they refer to specific principles that are effective in the treatment of post-traumatic psychiatric disorders. By helping the individual to verbalise their experience, talking re-establishes dissociated psychological functions. A process of reconsolidation enables sensory memory to be integrated into verbal memory. Supported by psychotherapy, language can be used to discover, or construct, a new sense of meaning for the individual. A single session of post-immediate or deferred debriefing has been found to have a miraculous effect on post-traumatic symptoms, confirmed by follow-up. When disorders are chronic and complex, however, treatment can last several months or years. In each case, although certain therapeutic principles are key, other psychotherapeutic and pharmacological treatments should be adapted to the individual's clinical situation, and the symptoms they present.

Drug therapy problems and medication discrepancies during care transitions in super-utilizers.

PubMed

Surbhi, Satya; Munshi, Kiraat D; Bell, Paula C; Bailey, James E

First, to investigate the prevalence and types of drug therapy problems and medication discrepancies among super-utilizers, and associated patient characteristics. Second, to examine the outcomes of pharmacist recommendations and estimated cost avoidance through care transitions support focused on medication management. Retrospective analysis of the pharmacist-led interventions as part of the SafeMed Program. A large nonprofit health care system serving the major medically underserved areas in Memphis, Tennessee. Three hundred seventy-four super-utilizing SafeMed participants with multiple chronic conditions and polypharmacy. Comprehensive medication review, medication therapy management, enhanced discharge planning, home visits, telephone follow-up, postdischarge medication reconciliation, and care coordination with physicians. Types of drug therapy problems, outcomes of pharmacist recommendations, estimated cost avoided, medication discrepancies, and self-reported medication adherence. Prevalence of drug therapy problems and postdischarge medication discrepancies was 80.7% and 75.4%, respectively. The most frequently occurring drug therapy problems were enrollee not receiving needed medications (33.4%), underuse of medications (16.9%), and insufficient dose or duration (11.2%). Overall 50.8% of the pharmacist recommendations were accepted by physicians and patients, resulting in an estimated cost avoidance of $293.30 per drug therapy problem identified. Multivariate analysis indicated that participants with a higher number of comorbidities were more likely to have medication discrepancies (odds ratio 1.23 [95% CI 1.05-1.44]). Additional contributors to postdischarge medication discrepancies were difficulty picking up and paying for medications and not being given necessary prescriptions before discharge. Drug therapy problems and medication discrepancies are common in super-utilizers with multiple chronic conditions and polypharmacy during transitions of care, and greater levels of comorbidity magnify risk. Pharmacist-led interventions in the SafeMed Program have demonstrated success in resolving enrollees' medication-related issues, resulting in substantial estimated cost savings. Preliminary evidence suggests that the SafeMed model's focus on medication management has great potential to improve outcomes while reducing costs for vulnerable super-utilizing populations nationwide.

The maximum work principle regarded as a consequence of an optimization problem based on mechanical virtual power principle and application of constructal theory

NASA Astrophysics Data System (ADS)

Gavrus, Adinel

2017-10-01

This scientific paper proposes to prove that the maximum work principle used by theory of continuum media plasticity can be regarded as a consequence of an optimization problem based on constructal theory (prof. Adrian BEJAN). It is known that the thermodynamics define the conservation of energy and the irreversibility of natural systems evolution. From mechanical point of view the first one permits to define the momentum balance equation, respectively the virtual power principle while the second one explains the tendency of all currents to flow from high to low values. According to the constructal law all finite-size system searches to evolve in such configurations that flow more and more easily over time distributing the imperfections in order to maximize entropy and to minimize the losses or dissipations. During a material forming process the application of constructal theory principles leads to the conclusion that under external loads the material flow is that which all dissipated mechanical power (deformation and friction) become minimal. On a mechanical point of view it is then possible to formulate the real state of all mechanical variables (stress, strain, strain rate) as those that minimize the total dissipated power. So between all other virtual non-equilibrium states, the real state minimizes the total dissipated power. It can be then obtained a variational minimization problem and this paper proof in a mathematical sense that starting from this formulation can be finding in a more general form the maximum work principle together with an equivalent form for the friction term. An application in the case of a plane compression of a plastic material shows the feasibility of the proposed minimization problem formulation to find analytical solution for both cases: one without friction influence and a second which take into account Tresca friction law. To valid the proposed formulation, a comparison with a classical analytical analysis based on slices, upper/lower bound methods and numerical Finite Element simulation is also presented.

Types of Psychotherapy for Pathological Gamblers

PubMed Central

2005-01-01

Several types of psychotherapy are currently used to treat pathological gamblers. These include Gambler's Anonymous, cognitive behavioral therapy, behavioral therapy, psychodynamic therapy, and family therapy. Research into which types of psychotherapy are the most effective for pathological gambling is limited but is a growing area of study. Group therapy, namely Gambler's Anonymous, provides peer support and structure. Cognitive behavior therapy aims to identify and correct cognitive distortions about gambling. Psychodynamic psychotherapy can help recovering gamblers address core conflicts and hidden psychological meanings of gambling. Family therapy is helpful by providing support and education and eliminating enabling behaviors. To date, no single type of psychotherapy has emerged as the most effective form of treatment. As in other addictive disorders, treatment retention of pathological gamblers is highly variable. Understanding the types of psychotherapy that are available for pathological gamblers, as well their underlying principles, will assist clinicians in managing this complex behavioral disorder.

The Role of Geophysics/Geology in the Environmental Discourse

NASA Astrophysics Data System (ADS)

Pfannkuch, H. O.

2013-12-01

Environmental problems are created by interaction between the Anthroposphere and Geosphere. Principles and laws governing behavior and interaction between them have to be fully understood to properly address environmental problems. A particular problem arises by inadequate communication between practitioners and/or decision makers in each sphere. A perfect analysis or solution in the Geosphere based solely on geophysical, geochemical principles will go nowhere if institutional, socio economic principles are ignored, or vice versa: no matter how well socio-economic relations are used in the Anthroposphere if they violate basic laws of physics . Two conceptual representations of the environment system are: Nöosphere with three domains: Physical, Institutional, Symbolic and their interactions. It is where environmental problems arise, decisions are made and implemented. The Physical Domain comprises physical, chemical, biological, geopsphere realities. Problems are treated by the scientific method. The Institutional Domain with economy, sociology, administration and political institutions, solves by negotiation (vote, ballot). The elements of the Symbolic Domain. spiritual, moral, religious, esthetic principles are revealed. All are intimately connected and interdependent. Activity in one affects the state of the others. A particularly strong and effective interactive relation exists between the Physical and the Institutional domains with regards to environmental problem definition, analysis and resolution. Hierarchic structure of interaction pyramid. Geosphere, Biosphere and Anthroposphere are open systems and are organized in successive levels forming a pyramid shape or aspect. The Geosphere forms the bottom level, the Anthroposphere the top. One fundamental attribute is that level (n) is limited by the restrictions obtaining in level (n-1), and conversely, level (n) represents the restrictions and limitations for level (n+1). In the environmental discourse this structural aspect is often overlooked which leads to two major sets of fallacies: 1. Discourse takes place across hierarchic levels with the unstated assumption that from the viewpoint of level (n) the same conditions, rules, equations and models hold in level (n-1) as on level (n) and are similarly compatible and follow the same rules. This leads to misunderstanding or misrepresentation of what analysis, modeling and solution methods at this level would be appropriate. 2. The fact that the bottom Geosphere level is the base level onto which all other levels are stacked including the topmost Anthroposphere. Each of the successive layers is restricted by the limitations of the Geosphere layer. Institutional and physical scientific realities both have to realize that solutions or redress are not solely within their domain. No matter what the economic or socio-political preferences might be, they cannot be implemented by violating fundamental physical, geological geo-ecological principles, nor can the physical world ignore currently acceptable principles of the institutional and symbolic realities. The role of Geophysics/Geology in the environmental discourse is to clearly state and apply the physical and thermodynamic principles to the Geosphere and Noösphere.

Stanol esters as a component of maximal dietary therapy in the National Cholesterol Education Program Adult Treatment Panel III report.

PubMed

Grundy, Scott M

2005-07-04

Use of plant stanols/sterols in forms that are sufficiently bioavailable for therapeutic effect should be a key element of maximal dietary therapy. This principle was recognized by National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) and has been amply confirmed by experimental studies in humans. Since the introduction of statins, dietary therapy for control of elevated low-density lipoprotein (LDL) cholesterol levels has received less attention. The time has come, however, to reassert the importance of maximal dietary therapy as a cost-effective means for treatment of elevated LDL concentrations and for lifetime prevention of coronary heart disease.

Reduced stress and improved physical functional ability in elderly with mental health problems following a horticultural therapy program.

2018-06-01

This study aimed to determine the effects of a plant cultivation-based horticultural therapy program for elderly people with mental health problems. Pre- and post-test design with experimental and control groups. Twenty-eight elderly Korean people with mental health problems participated from April to June 2017 at a farm located in Suwon, South Korea. The participants were randomly assigned to either the control (n = 14) or horticultural therapy group (n = 14); the latter participated in once-weekly sessions of a previously designed 10-session horticultural therapy program. The pre-test occurred 1 week before starting the horticultural therapy program. The post-test was completed within 1 week after finishing the final program session. Cortisol levels were measured in saliva samples collected from both groups. The Senior Fitness Test was used to assess physical functional ability in both groups. In the horticultural therapy group, the cortisol levels decreased significantly from before to after the horticultural therapy program, and the post-test scores for six subtests of the Senior Fitness Test improved significantly. No significant improvements were seen in either measure in the control group. This study demonstrates the potential ability of horticultural therapy to improve the stress levels and physical functional abilities of elderly people with mental health problems. In future studies, it would be interesting to verify the long-term effects of this horticultural therapy program and to compare its effects with regard to sex, age, and various mental symptoms.

2018-06-01

The purpose of this study was to determine the evolution of neurocognitive problems from therapy completion to long-term follow-up in survivors of childhood acute lymphoblastic leukemia treated with chemotherapy only. We evaluated whether attention problems observed at therapy completion evolve into long-term executive dysfunction in 158 survivors treated on a single institution protocol. Treatment data (high-dose intravenous methotrexate exposure [serum concentration] and triple intrathecal chemotherapy injections) were collected. Parent report of behavior and direct cognitive testing of survivors was conducted at end of therapy, and survivors completed neurocognitive testing when > 5 years post-diagnosis. At the end of chemotherapy, survivors (52% female; mean age 9.2 years) demonstrated higher frequency of impairment in sustained attention (38%) and parent-reported inattention (20%) compared to population expectations (10%). At long-term follow-up, survivors (mean age 13.7 years; 7.6 years post-diagnosis) demonstrated higher impairment in executive function (flexibility 24%, fluency 21%), sustained attention (15%), and processing speed (15%). Sustained attention improved from end of therapy to long-term follow-up (p < 0.001). Higher methotrexate AUC and greater number of intrathecal injections were associated with attention problems (p = 0.009, p = 0.002, respectively) at the end of chemotherapy and executive function (p < 0.001, p = 0.02, respectively) problems at long-term follow-up. Attention problems at the end of therapy were not associated with executive function problems at long-term follow-up (p's > 0.05). The direct effect of chemotherapy exposure predicted outcomes at both time points. Survivors should be monitored for neurocognitive problems well into long-term survivorship, regardless of whether they show attention problems at the end of therapy. Treatment exposures are the best predictor of long-term complications.

A Symptom Inventory completed by 656 cancer patients nationwide before and after chemotherapy, radiation therapy, or chemotherapy plus radiation therapy was analysed to determine if treatment type, race (Black vs White), and pretreatment expectations influenced post-treatment skin reactions. Subsequent analysis of a local Symptom Inventory completed weekly for 5 weeks by 308 patients receiving radiation therapy examined severity of reported skin reactions. Significantly more patients receiving radiation therapy had stronger expectations of skin problems (62%) than patients receiving chemotherapy (40%, P=0.001) or chemotherapy plus radiation therapy (45%, P=0.003). Overall, expectations did not correlate with patient reported post-treatment skin problems in white (r=0.014, P=0.781) or black (r=0.021, P=0.936) patients. Although no significant difference was found between black and white patients in their pretreatment expectations of skin problems (P=0.32), black patients (10 out of 18, 56%) reported more skin problems than white patients (90 out of 393, 23%, P=0.001). Similarly, the local study showed that significantly more black patients (1 out of 5, 20%) reported severe skin reactions at the treatment site than white patients (12 out of 161, 8%). A direct correlation was observed between severity of skin problems and pain at the treatment site (r=0.541, P<0.001). Total radiation exposure did not significantly correlate with the report of skin problems at the treatment site for white or black patients. Overall, black patients reported more severe post-treatment skin problems than white patients. Our results suggest that symptom management for post-treatment skin reactions in cancer patients receiving radiation treatment could differ depending on their racial background. PMID:17565347

Background Although radiation therapy is a primary treatment for craniopharyngioma, it can exacerbate existing problems related to the tumor and pre-irradiation management. Survival is often marked by neurologic deficits, panhypopituitarism, diabetes insipidus, cognitive deficiencies and behavioral and social problems. Procedure The Achenbach Child Behavior Checklist (CBCL) was used to evaluate behavioral and social problems during the first five years of follow-up in 27 patients with craniopharyngioma treated with conformal radiation therapy. Results All group averages for the CBCL scales were within the age-typical range at pre-irradiation baseline. Extent of surgical resection was implicated in baseline differences for the Internalizing, Externalizing, Behavior Problem and Social scores. Significant longitudinal changes were found in Internalizing, Externalizing, Behavior Problem and School scores that correlated with tumor and treatment related factors. Conclusions The most common variables implicated in post-irradiation behavioral and social problems were CSF shunting, presence of an Ommaya reservoir, diabetes insipidus, and low pre-irradiation growth hormone levels.
