  1. Teaching Critical Reflection

    ERIC Educational Resources Information Center

    Smith, Elizabeth

    2011-01-01

    Despite long-standing commitment to the notion of critical reflection across the healthcare professions it is unusual for critical theory and practice to be taught as explicit subjects in healthcare higher education. There is evidence to show that reflective techniques such as critical portfolios and reflective diaries can help students to…

  2. [Life satisfaction--a dimension of psychotherapeutical prevention. Critical reflections and results of empirical research].

    PubMed

    Leitner, Anton; Schuch, Hans Waldemar

    2004-12-01

    Psychotherapy has historically been developed on ill people and is applied in the system treating the sick. A healthy person who has no complaints is only in exceptional cases the subject of psychotherapeutic inquiries as to his/her experiences and behaviour. In this article, the pathologising basic attitude is abandoned and the appreciation of one's own life over one's lifetime and the accompanying complex possibilities of prevention are given. The empirical findings provided cover areas of life which show impairment and in which psychotherapy can cause positive changes. Assessments of life contentment are shown by means of various psychotherapeutic methods. The conclusion is that psychotherapy aims at a "productive therapeutic" change with immediate consequences of application.

  12. Evidence for practice, epistemology, and critical reflection.

    PubMed

    Avis, Mark; Freshwater, Dawn

    2006-10-01

    Evidence-based practice (EBP) has become a critical concept for ethical, accountable professional nursing practice. However, critical analysis of the concept suggests that EBP overemphasizes the value of scientific evidence while underplaying the role of clinical judgement and individual nursing expertise. This paper explores the empiricist position that valid evidence is the basis for all knowledge claims. We argue against the positivist idea that science should be regarded as the only credible means for generating evidence on which to base knowledge claims. We propose that the process of critically reflecting on evidence is a fundamental feature of empirical epistemology. We suggest that critical reflection on evidence derived from science, arts and humanities and, in particular, nursing practice experience can provide a sound basis for knowledge claims. While we do not attempt to define what counts as evidence, it is argued that there is much to be gained by making the processes of critical reflection explicit, and that it can make a valid contribution to expert nursing practice, without recourse to irreducible concepts such as intuition.

  15. Remyelination strategies in multiple sclerosis: a critical reflection.

    PubMed

    Kipp, Markus

    2016-01-01

    Remyelination is the natural repair mechanism of demyelination and can be a highly efficient process in multiple sclerosis. However, in the majority of lesions, this regenerative approach is incomplete or fails. It is believed that remyelination protects against progressive axonal damage and thus long-term disability in patients with multiple sclerosis. For this reason, therapeutic promotion of remyelination represents an attractive option for preventing disease progression. In this editorial we casts a critical eye over the most frequently used experimental settings which aim to uncover potential remyelination promoting drugs. This article reflects upon the personal opinion of the author who currently used animal models allow to assess the potency of pharmacological interventions to accelerate, but not to induce myelin repair. Furthermore, it is discussed how remyelination and neuroprotection might well be two separate entities. Thus, induction of remyelination does not necessarily prevent disease progression in multiple sclerosis patients.

  18. Workplace Bullying Prevention: A Critical Discourse Analysis

    PubMed Central

    JOHNSON, Susan L.

    2016-01-01

    Aim To analyze the discourses of workplace bullying prevention of hospital nursing unit managers and in the official documents of the organizations where they worked. Background Workplace bullying can be a self-perpetuating problem in nursing units. As such, efforts to prevent this behavior may be more effective than efforts to stop the behavior. There is limited research on how healthcare organizations characterize their efforts to prevent workplace bullying. Design This was a qualitative study. Method Critical discourse analysis and Foucault’s writings on governmentality and discipline were used to analyze data from interviews with hospital nursing unit managers (n=15) and organizational documents (n=22). Data were collected in 2012. Findings The discourse of workplace bullying prevention centered around three themes: prevention of workplace bullying through managerial presence, normalizing behaviors and controlling behaviors. All three are individual level discourses of workplace bullying prevention. Conclusion Current research indicates that workplace bullying is a complex issue with antecedents at the individual, departmental and organizational level. However, the discourse of the participants in this study only focused on prevention of bullying by moulding the behaviors of individuals. The effective prevention of workplace bullying will require departmental and organizational initiatives. Leaders in all types of organizations can use the results of this study to examine their organizations’ discourses of workplace bullying prevention to determine where change is needed. PMID:26010268

    The conceptions of reflective practice in education have their roots at least partly in the work of Dewey, who describes reflection as "the active, persistent, and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends" (Dewey 1933, p.9).…

  20. How reflective practice improves nurses' critical thinking ability.

    PubMed

    Cirocco, Maria

    2007-01-01

    Purposeful reflection is consistent with adult learning theory. It is known to lead to a deeper understanding of issues and to develop judgment and skill. Required by law to ensure members' competence in their professional practice, the College of Nurses of Ontario recommends and has developed a tool for evaluating reflective practice. The tool focuses on key attributes said to be demonstrated by competent practitioners, including critical thinking (CT) and job knowledge. This study aimed to determine whether nurses engage in reflective practice and whether they perceive that it enhances their CT ability. Surveys were sent to 60 gastroenterology nurses at a large teaching hospital; 34 surveys were anonymously returned. All respondents engaged in reflective practice, and 24 reported using the college's tool. Nineteen respondents strongly agreed that their nursing practice had improved as a result. Critical thinking is difficult to assess because of a lack of clear-cut performance criteria. Improvement of CT was difficult to evaluate from the responses, even though all respondents participated in reflective practice. Both CT and reflective practice need to be better defined in order to examine and explain their relationship.

  1. Reconsidering nutrition science: critical reflection with a cultural lens

    PubMed Central

    2014-01-01

    Background European culture gave birth to modern science as a means to investigate and explain the natural world. The biomedical disciplines that have since emerged, including nutrition, presuppose a web of basic presuppositions, background assumptions and implicit cultural values that are often overlooked and escape peer review. These "hidden subjectivities" are widely taken-for-granted while exerting a powerful hold on the scope, direction and patterns of disciplinary thought. Nutrition science currently has no accepted means of collectively attending to hidden subjectivities embedded within its methods and practice. Here I propose that directing inquiry into these dimensions holds potential to advance our discipline. Methods This critically reflective approach emerged from critical theory and the practice of cross-cultural engagement (CCE). CCE deliberately seeks out and critically engages food and health understandings of non-European cultures. Its protocol includes cognitive frameshifting, a practice of temporarily stepping outside of habitual thought patterns and into a non-biomedical framework of background assumptions. A cultural lens metaphor derives from CCE practice and is forwarded here as a viable means for restoring critically reflective attention to hidden subjectivities while also inviting further CCE practice within the discipline. Results Critical reflection with a cultural lens allows cognitive attachments to materialism, reductionism, mechanistic thought, naïve realism, control over nature and pervasive subject-object dichotomies between mind and matter, scientist and nature, experience and reality, among many others to become more available for critical consideration. Culturally diverse food and health understandings otherwise dismissed as "unscientific" or held in abeyance gain value as alternative assumptive frameworks and cognitive models that can be temporarily inhabited for further intercultural reflection and insight. Conclusion Critical

    2011-11-01

    A series of experiments were carried out in 1963 at the Oak Ridge National Laboratory Critical Experiments Facility (ORCEF) for use in space reactor research programs. A core containing 93.2% enriched UO2 fuel rods was used in these experiments. The first part of the experimental series consisted of 253 tightly-packed fuel rods (1.27 cm triangular pitch) with graphite reflectors [1], the second part used 253 graphite-reflected fuel rods organized in a 1.506 cm triangular pitch [2], and the final part of the experimental series consisted of 253 beryllium-reflected fuel rods with a 1.506 cm triangular pitch. [3] Fission rate distribution and cadmium ratio measurements were taken for all three parts of the experimental series. Reactivity coefficient measurements were taken for various materials placed in the beryllium reflected core. The first part of this experimental series has been evaluated for inclusion in the International Reactor Physics Experiment Evaluation Project (IRPhEP) [4] and the International Criticality Safety Benchmark Evaluation Project (ICSBEP) Handbooks, [5] and is discussed below. These experiments are of interest as benchmarks because they support the validation of compact reactor designs with similar characteristics to the design parameters for a space nuclear fission surface power systems.

    Amar, Angela Frederick

    2008-01-01

    Violence against women is a major public health concern. This paper describes an educational strategy to increase nursing students' understanding of the experience of violence and to foster recognition and intervention with victims of violence. Students in an elective course were asked to critically reflect on the personal stories of victims/survivors of violence. The assignment provided four learning opportunities that include examination of societal myths on sexual victimization, understanding the lived experience of the victim, exploration of personal beliefs and values, and the relationship of the individual's experience to theoretical content of the course. Students gave permission for the use of quotes from papers to illustrate the learning opportunities.

    2013-10-01

    Critically reflective dialogues (CRD) are important for knowledge sharing and creating meaning in communities. CRD includes different aspects: being open about mistakes, critical opinion sharing, asking for and giving feedback, experimentation, challenging groupthink and research utilisation. In this article we explore whether CRD aspects change over time, through a study of two dialogues each from six different communities of veterinary health professionals. Change was studied from the perspective of observations, through analysing transcripts of dialogues, and from the perspective of community members' perceptions, through an evaluative discussion with members. The results showed that some communities became more open about mistakes, a finding that is related to an increase in trust. Other observed aspects of CRD seemed to be fairly stable over time. Community members perceived research utilisation and asking for and giving feedback to have been increased. From an analysis of perceptions of the community members it emerged that limited interaction could be associated with the epistemological conceptions of community members.

    Margaret A. Marshall; John D. Bess

    2009-11-01

    A series of twelve experiments were conducted in the mid 1950's at the Oak Ridge National Laboratory Critical Experiments Facility to determine the critical conditions of a semi-infinite water-reflected slab of aqueous uranium oxyfluoride (UO2F2). A different slab thickness was used for each experiment. Results from the twelve experiment recorded in the laboratory notebook were published in Reference 1. Seven of the twelve experiments were determined to be acceptable benchmark experiments for the inclusion in the International Handbook of Evaluated Criticality Safety Benchmark Experiments. This evaluation will not only be available to handbook users for the validation of computer codes and integral cross-section data, but also for the reevaluation of experimental data used in the ANSI/ANS-8.1 standard. This evaluation is important as part of the technical basis of the subcritical slab limits in ANSI/ANS-8.1. The original publication of the experimental results was used for the determination of bias and bias uncertainties for subcritical slab limits, as documented by Hugh Clark's paper 'Subcritical Limits for Uranium-235 Systems'.

    Kjellberg, Göran

    2010-03-24

    The high number of divorces could partly be attributed to a lack of sexual desire in the couples linked to the prevailing sexual hyperstimulation in society. Sexual harassment on the internet and the exposition of abuse incidents in the mass media contribute to the increased numbers of child sexual abuse. Enhanced awareness among adults about the potential dangers of television and the internet, as well as psychotherapeutic treatment of abusers and their victims would be of preventative importance. Psychotherapeutic treatment of adolescents in situations of developmental "break-down" could result in a more mature sexuality contributing to fewer cases of sexual abuse and to the stabilisation of future couples on the long-term.

  8. Researching "race" in lesbian space: a critical reflection.

    PubMed

    Held, Nina

    2009-01-01

    Feminist researchers have acknowledged that racial differences between researcher and researched impact on the research process; however, there has been little concern with how "race" is actually made in/through the research process. If we think "race" as performative and as always in the process of being made then this theoretical claim has crucial implications for research encounters. In this article the author draws on her own research, which focuses on processes of racialization. This ethnographic study was conducted in two lesbian bars in the North West of England. The article illustrates different ways of how "race," in particular Whiteness, operated during the research process. The author critically reflects on her role in "race making" during this process and highlights the importance of acknowledging that researchers are also complicit in this making when doing research where "race" is not the central focus.

    Murphy, Roger; Cox, Karen; Steward, William

    2011-01-01

    Objectives The experiences of patients diagnosed with advanced incurable cancer and the doctors who conducted their medical consultations were studied in order to improve the understanding of what happens in consultations, when bad news is disclosed. The major objective of the study was to critically reflect upon doctor-patient communication, in such situations, with a view to considering future strategies for doctors’ continuing professional development. Methods Sixteen patients and sixteen Oncologists, from a cancer centre in the UK were recruited into this ethnographic study. One hundred and fifteen episodes of data were collected from audio recorded consultations; interviews with doctors and patients and their relatives and observations of consultations. These data were analysed using a constant comparison method. Results Interactions between doctors and patients are complex and consultations can be challenging for both of them. Some doctors spoke openly about their need for additional support to enhance their communication related competencies within Oncology consultations. These doctors wanted to observe their peers conducting consultations. They also wanted to receive feedback about their own clinical practices. These doctors stated that they wanted an open culture whereby they could talk freely about difficult and emotionally challenging consultations without fear of being considered incompetent by their Consultants, who act in a clinical supervisory role. Conclusions To help practitioners consolidate their practice in such settings it is necessary to develop better collaborations among practitioners within clinical practice. Providing individual supervisory sessions or group workshops can facilitate reflective learning and provide an open and supportive learning culture.

  10. Exploring problems encountered among experienced nurses using critical reflective inquiry: implications for nursing professional development.

    Asselin, Marilyn E; Schwartz-Barcott, Donna

    2015-01-01

    This study explored problems encountered by nurses using critical reflective inquiry to examine clinical situations and the impact of group discussion on the reflective process. Secondary qualitative analysis of 19 reflective situations, rom a reflection continuing education program, revealed that nurses had problematic pauses in reflection and were stuck in cyclical self-questioning. Peer group discussion prompted deeper reflection. Experienced nurses may need assistance to enhance the comprehensiveness, depth, and scope of reflection on practice situations.

    Critical thinking (CT) is considered to be foundational for the development of RN clinical reasoning. Reflective journaling has been used as an educational strategy to support the development of CT. This project's purpose was to explore how using reflective journaling about CT dispositions with RNs in a fellowship program might influence RN's use of CT dispositions. This descriptive, qualitative study used content analysis as the method to analyze journal entries focused on seven CT dispositions: inquisitiveness, systematicity, open mindedness, analyticity, truth seeking, CT maturity, and CT confidence written by RNs in the first 7 weeks of their fellowship program. Based on the content analysis of journal entries, two major descriptive themes emerged: Development of Critical Thinking Is a Process That Develops During a Period of Time, and Purposefully Engaging Critical Thinking Dispositions May Help Prevent Negative Patient Outcomes. The purposeful use of CT dispositions as described in the journal entries also helped to guide the RN's individual learning. J Contin Educ Nurs. 2016;47(7):321-329.

    PubMed

    Usher, K; Tollefson, J; Francis, D

    2001-01-01

    This paper outlines a research project aimed at changing the levels of reflection of preregistration nursing students in a tertiary institution. Whilst reflection is widely espoused now in nursing, few studies have been found that identify whether the level of reflective writing can be identified or developed by students. Anecdotal and research evidence (Powell 1989; van Manen 1977) however indicates that most student reflective writing occurs at the technical level. A descriptive exploratory study using both qualitative and quantitative techniques was undertaken to apply van Manen's (1977) levels in a structured way in an attempt to facilitate the student's understanding and use of the levels in their reflective writing. The findings of the study indicate that student self evaluation and identification of the levels in their own writing can lead to change in the levels of critical reflective writing achieved by undergraduate students.

  5. Reflections on the criticality of special actinide elements

    SciTech Connect

    Clayton, E.D.

    1987-04-01

    During recent years, the list of nuclides known to be capable of supporting a chain reaction has substantially increased. Since the criticality aspects for some of these nuclides differ in important respects from those of the most common fissile nuclides, /sup 235//sub 92/U, and /sup 239//sub 94/Pu, a new term, ''fissible'' was recently proposed in nuclear engineering to help distinguish differences. Activation energies for fission have been calculated for 41 of the actinide isotopes which are grouped according to four types of nuclides, those with even-Z, even-N, odd-Z, odd-N, odd-Z, even-N, and even-Z, odd-N. With the possible exception of /sup 237//sub 92/U, all fissible isotopes listed have even N. The activation energy for fission is less in the case of the even-Z, even-N isotopes, but almost without eception it is the odd-N isotopes that undergo fission with thermal neutrons and which constitute the principal criticality problem. This paper reviews the criticality and fissionability aspects of the fissile and fissible actinide isotopes. The criticality of aqueous mixtures of fissile and fissible isotopes also is briefly discussed, including limits for criticality control.

    1975-01-01

    Experiments and theoretical studies are being conducted for NASA on critical assemblies with one-meter diam by one-meter long low-density cores surrounded by a thick beryllium reflector. These assemblies make extensive use of existing nuclear propulsion reactor components, facilities, and instrumentation. Due to excessive porosity in the reflector, the initial critical mass was 19 kg U(93.2). Addition of a 17-cm-thick by 89-cm-diam beryllium flux trap in the cavity reduced the critical mass to 7 kg when all the uranium was in the zone just outside the flux trap. A mockup aluminum UF6 container was placed inside the flux trap and fueled with uranium-graphite elements. Fission distributions and reactivity worths of fuel and structural materials are available. These results will be used to guide the design of a prototype plasma core reactor which will test energy removal by optical radiation.

    the labor market to maintain economic welfare (1). Moreover, as a consequence of population aging (2-6), longevity, rapid changes in technology (7, 8) and changes in the nature of work (1), both the need to promote sustainable employability of individuals in society and the complexity to succeed in doing so increase even further. Only recently, van der Klink et al provided the first definition of the concept in the international scientific literature (1, p74): "Sustainable employability means that throughout their working lives, workers can achieve tangible opportunities in the form of a set of capabilities. They also enjoy the necessary conditions that allow them to make a valuable contribution through their work, now and in the future, while safeguarding their health and welfare. This requires, on the one hand, a work context that facilitates this for them and, on the other, the attitude and motivation to exploit these opportunities." This definition is accompanied by an equally recent operationalization of SE as a set of capabilities (9). Moreover, the definition itself also appeared in an earlier Dutch publication (10), which other international publications about SE most commonly refer to [ie, in comparison with other definitions in the non-international (eg, Dutch) literature] (11-13). As mentioned, the present paper provides a critical reflection on van der Klink et al's aforementioned definition of SE (1). Merits Van der Klink et al's definition of SE (1) has three important merits. First, SE is seen as a multidimensional construct. It is presented as consisting of a broad set of opportunities for employees to create value for themselves and for their employer that cover various aspects of working. Moreover, the individual's health and well-being as well as attitudinal and motivational aspects are included in the definition as well. This acknowledgement of the multidimensionality of SE is favorable, as it illustrates the complexity of the construct and of what

    We present a critical appraisal of the adaptation to the 4th European Guidelines on Cardiovascular Disease Prevention in Clinical Practice carried out by The Spanish Interdisciplinary Committee for Cardiovascular Disease Prevention (CEIPC), which is based on: 1) the removal, by the CEIPC, of important restrictions on the start of drug therapy that are contained in the European guide 2) the existence of internal contradictions and differing recommendations regarding the goals of LDL in the several publications of the CEIP adaptation; and 3) and the almost total lack of necessary discussion about risk tables in Spain. Therefore, it makes a critical appraisal of some of the most important clinical recommendations shared by the CEIPC and the European guide that are not supported by clinical evidence, like the implicit proposal of using the estimated cardiovascular risk as a target for treatment, the criteria to begin the antihypertensive drug therapy and therapeutic goals for blood pressure, LDL-cholesterol and HbA1c.

    2015-05-01

    Recently, the Vaccines to Vaccinate (v2V) initiative was reconfigured into the Partnership for Dengue Control (PDC), a multi-sponsored and independent initiative. This redirection is consistent with the growing consensus among the dengue-prevention community that no single intervention will be sufficient to control dengue disease. The PDC's expectation is that when an effective dengue virus (DENV) vaccine is commercially available, the public health community will continue to rely on vector control because the two strategies complement and enhance one another. Although the concept of integrated intervention for dengue prevention is gaining increasingly broader acceptance, to date, no consensus has been reached regarding the details of how and what combination of approaches can be most effectively implemented to manage disease. To fill that gap, the PDC proposed a three step process: (1) a critical assessment of current vector control tools and those under development, (2) outlining a research agenda for determining, in a definitive way, what existing tools work best, and (3) determining how to combine the best vector control options, which have systematically been defined in this process, with DENV vaccines. To address the first step, the PDC convened a meeting of international experts during November 2013 in Washington, DC, to critically assess existing vector control interventions and tools under development. This report summarizes those deliberations.

  2. Infantile amnesia reflects a developmental critical period for hippocampal learning

    2016-01-01

    Episodic memories formed during the first postnatal period are rapidly forgotten, a phenomenon known as infantile amnesia. In spite of this memory loss, early experiences influence adult behavior, raising the question of which mechanisms underlie infantile memories and amnesia. Here we show that in rats an experience learned during the infantile amnesia period is stored as a latent memory trace for a long time; indeed, a later reminder reinstates a robust, context-specific and long-lasting memory. The formation and storage of this latent memory requires the hippocampus, follows a sharp temporal boundary, and occurs through mechanisms typical of developmental critical periods, including brain-derived-neurotrophic-factor (BDNF)- and metabotropic-glutamate-receptor-5 (mGluR5)-dependent expression switch of the N-methyl-D-aspartate receptor subunits 2B-2A. BDNF or mGlur5 activation after training rescues the infantile amnesia. Thus, early episodic memories are not lost, but remain stored long-term. These data suggest that the hippocampus undergoes a developmental critical period to become functionally competent. PMID:27428652

    2012-01-01

    Medical ethics as a scholarly discipline and a system of moral principles that apply values and judgments to the practice of medicine encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, anthropology and sociology. As such there are a number of values in medical ethics such as autonomy, non-maleficence, confidentiality, dignity, honesty, justice and beneficence, among others. These values act as guidelines for professionals in the medical fraternity and are therefore used to judge different cases in the fraternity. For purposes of this work, this paper examines the principle of beneficence in biomedicine. Using both hypothetical cases and others in real life situations, the paper reflects on the implications of beneficence in biomedicine. It argues that the principle of beneficence is a prima facie obligation that should "always be acted upon unless it conflicts on a particular occasion with an equal or stronger principle".

    2010-12-01

    One challenge facing dental hygiene, as well as dental, education is to identify clinical teaching strategies promoting critical thinking and clinical reasoning. These skills are crucial elements in the practice of dental hygiene. A two-group design (intervention, n=28, and control, n=30) assessed first-year dental hygiene students using pre-and post-Health Science Reasoning Test (HSRT) scores to evaluate the effect of reflective blogging on critical thinking skills. A reflective blog rubric, based on Mezirow's levels of reflection, determined if reflective blogging increased the level of reflection for dental hygiene students. The results suggest within this nonprobability sample that reflective blogging did not produce a significant change in students' HSRT scores (p>0.05). However, analyses of reflective blog rubric scores demonstrated statistically significant improvements (p<0.05) in students' levels of reflection. Furthermore, data analysis revealed a correlation (p<0.05) between HSRT subscale scores and the element of reflection scores for the intervention group. This study addressed needs of the dental and dental hygiene education community by examining the use of blogs, an emerging technology, as a tool for reflecting on clinical experiences and, in turn, for promoting critical thinking.

    Clean criticality data were obtained from molybdenum-reflected cylindrical uranyl-fluoride-water solution reactors. Using ENDF/B molybdenum cross sections, a nine energy group two-dimensional transport calculation of a reflected reactor configuration predicted criticality to within 7 cents of the experimental value. For these reactors, it was necessary to compute the reflector resonance integral by a detailed transport calculation at the core-reflector interface volume in the energy region of the two dominant resonances of natural molybdenum.

    The purpose of this study was to establish interrater reliability of the Critical Thinking Scale (CTS), a teacher-accessible tool designed to measure the critical thinking of baccalaureate nursing students as evidenced in their reflective writing about their practice experiences.The study is an extension of an earlier pilot test of the CTS. Graduating students from a nursing program at a small liberal arts college were asked to write about a significant practice experience encountered during their last clinical course. Three teachers used the CTS to independently evaluate the students' writing. California Critical Thinking Skills Test (CCTST) scores provided a standard measure of critical thinking. Results indicated statistically significant positive relationships between the CCTST total critical thinking score and mean teacher ratings using the CTS. Meaningfully significant interrater reliability ratings for the CTS were also found. With further development, the CTS has promise as an appropriate tool to evaluate students' reflective writing for evidence of critical thinking.

    This study sought to identify characteristics of clinically situated critical thinking in nursing students' reflections, originally part of a study guided by Richard Paul's model of critical thinking. Nurses are expected to apply critical thinking in all practice situations to improve health outcomes, including patient safety and satisfaction. In a previous study, Paul's model of critical thinking was used to develop questions for reflective writing assignments. Within that study, 30 nursing students completed six open-ended narratives of nurse-patient clinical encounters during an 8-week period. Improvements were seen in critical thinking scores after the intervention. This article reports the qualitative analysis of the content of six open-ended narratives. Six overarching themes were identified and combined into a tentative conceptual model. Faculty's understanding of the characteristics of critical thinking in the context of clinical education will help them to teach and evaluate students' progress and competencies for future practice.

    Learning circles are an enabling process to critically examine and reflect on practices with the purpose of promoting individual and organizational growth and change. The authors adapted and developed a learning circle strategy to facilitate open discourse between registered nurses, clinical leaders, clinical facilitators and students, to critically reflect on practice experiences to promote a positive learning environment. This paper reports on an analysis of field notes taken during a critical reflection process used to create an effective learning community in the workplace. A total of 19 learning circles were conducted during in-service periods (that is, the time allocated for professional education between morning and afternoon shifts) over a 3 month period with 56 nurses, 33 students and 1 university-employed clinical supervisor. Participation rates ranged from 3 to 12 individuals per discussion. Ten themes emerged from content analysis of the clinical learning issues identified through the four-step model of critical reflection used in learning circle discussions. The four-step model of critical reflection allowed participants to reflect on clinical learning issues, and raise them in a safe environment that enabled topics to be challenged and explored in a shared and cooperative manner.

    The global population of wild tigers remains dangerously low at fewer than 3500 individuals. Habitat loss, along with poaching, can undermine the international target recovery of doubling the number of wild tigers by 2022. Using a new satellite-based monitoring system, we analyzed 14 years of forest loss data within the 76 landscapes (ranging from 278 to 269,983 km(2)) that have been prioritized for conservation of wild tigers. Our analysis provides an update of the status of tiger habitat and describes new applications of technology to detect precisely where forest loss is occurring in order to curb future habitat loss. Across the 76 landscapes, forest loss was far less than anticipated (79,597 ± 22,629 km(2), 7.7% of remaining habitat) over the 14-year study period (2001-2014). Habitat loss was unevenly distributed within a subset of 29 landscapes deemed most critical for doubling wild tiger populations: 19 showed little change (1.5%), whereas 10 accounted for more than 98% (57,392 ± 16,316 km(2)) of habitat loss. Habitat loss in source population sites within 76 landscapes ranged from no loss to 435 ± 124 km(2) ([Formula: see text], SD = 89, total = 1676 ± 476 km(2)). Doubling the tiger population by 2022 requires moving beyond tracking annual changes in habitat. We highlight near-real-time forest monitoring technologies that provide alerts of forest loss at relevant spatial and temporal scales to prevent further erosion.

  1. Using Edward de Bono's six hats game to aid critical thinking and reflection in palliative care.

    PubMed

    Kenny, Lesley J

    2003-03-01

    This article describes the use of a creative thinking game to stimulate critical thinking and reflection with qualified health professionals undertaking palliative care education. The importance of reflective practice in nursing is well documented and numerous models are available. However, the author as a nurse teacher has found that many of these models are either too simple or too complex to be valuable in practice. The six hats game, devised by Edward de Bono, is a method that stimulates a variety of types of thinking and when used as a means of reflection helps students to become more critical about their practice. Using this game with a palliative care case study the author demonstrates how thinking more creatively about the patients' perceived needs and problems can assist in developing reflective skills. The article concludes with a discussion on some of the challenges of using this method and suggestions for future practical uses.

  2. Preeclampsia: Reflections on How to Counsel About Preventing Recurrence.

    2015-10-01

    Preeclampsia is one of the most challenging diseases of pregnancy, with unclear etiology, no specific marker for prediction, and no precise treatment besides delivery of the placenta. Many risk factors have been identified, and diagnostic and management tools have improved in recent years. However, this disease remains one of the leading causes of maternal morbidity and mortality worldwide, especially in under-resourced settings. A history of previous preeclampsia is a known risk factor for a new event in a future pregnancy, with recurrence rates varying from less than 10% to 65%, depending on the population or methodology considered. A recent review that performed an individual participant data meta-analysis on the recurrence of hypertensive disorders of pregnancy in over 99 000 women showed an overall recurrence rate of 20.7%; when specifically considering preeclampsia, it was 13.8%, with milder disease upon recurrence. Prevention of recurrent preeclampsia has been attempted by changes in lifestyle, dietary supplementation, antihypertensive drugs, antithrombotic agents, and others, with much uncertainty about benefit. It is always challenging to treat and counsel a woman with a previous history of preeclampsia; this review will be based on hypothetical clinical cases, using common scenarios in obstetrical practice to consider the available evidence on how to counsel each woman during pre-conception and prenatal consultations.

    Abstract Background To prevent childhood obesity, parents and their children's healthcare providers need to engage in effective dialogue. We know much about mothers' experiences, but very little about fathers' experiences. Methods We explored African-American, Caucasian, and Latino fathers' perceptions and experiences communicating with their children's provider during clinic visits regarding weight, diet, and physical activity. Focus groups (n=3), grouped by race/ethnicity, including a total of 24 fathers, were conducted. The men were asked open-ended questions; responses were recorded and transcribed, and analyzed using ATLAS.ti. Results Findings revealed that these fathers were involved in their children's healthcare and found providers to be helpful partners in keeping their children healthy, yet they generally felt “left out” during clinic appointments. The quality of the relationship with their children's provider influenced how receptive fathers were to discussing their children's weight, diet, and physical activity behaviors. Fathers made suggestions to help improve communication between providers and fathers, such as personalizing the discussion. Conclusions These fathers expressed strong feelings about the provider–parent relationship when discussing weight, diet, and physical activity. PMID:23472966

    We have used direct inversion of x-ray reflectivity data to extract the liquid-vapor interface composition profile and the related critical scaling function of a binary mixture of dodecane and tetrabromoethane. The mixture was in the one-phase region above its critical point. The results indicate the formation of a monolayer of the lower surface tension component followed by an abrupt change to a mixed composition which gradually relaxes to the bulk composition deep within the fluid.

  6. From idealistic helper to enterprising learner: critical reflections on personal development through experiences from Afghanistan.

    PubMed

    Wickford, Jenny; Rosberg, Susanne

    2012-05-01

    There is little written about the cultural, social, and ethical challenges encountered by physiotherapists engaging in development work. This article takes a critical perspective on what it means to engage in development work as an expatriate physiotherapist, through a self-critical reflection on experiences from Afghanistan. The field notes from an ethnographic study of a development project conducted in Afghanistan were analysed to explore the transformative process of personal and professional development of the development worker. The critical reflective process entailed a change in meaning perspective, described as a shift from the position of an Idealistic Helper to an Enterprising Learner. Of importance in this process were "disorienting dilemmas" that challenged personal perceptions. Critical reflection over such dilemmas led to deeper understanding facilitating the process of change. The essential lesson learned is that the baseline for understanding others is an understanding of one's own meaning perspectives and manner of participation in relation to others and their context. The insights gained have implications for physiotherapists working in development contexts, for other development workers, and for physiotherapists working with patients in clinical practice in a nondevelopment context. Exploring how to collaborate in development contexts could be done using reflective groups with expatriate and local physiotherapists and/or patients. This could lead to greater understanding of oneself, each other, and the local context.

    2007-08-01

    The purpose of this paper is to present a framework to guide critical thinking through reflective journaling, and describe how a group of 20 Middle Eastern nurses used reflective journaling to enhance their practice. Journal documentation was used during clinical practicum to foster the development of critical thinking in order to assist nurses when analysing and evaluating their clinical experiences. The findings from this study demonstrated that nurses accepted the framework for journal documentation because it provided structure for reflection, speculation, synthesis and metacognition of events experienced during clinical practice. Journaling gave nurses the opportunity to transfer thoughts onto paper and write down subjective and objective data, and created dialogue between the nurse educators and nurses. They were engaged in productive and positive activity to enhance their nursing practice. Nurses also commented that writing helped to develop their confidence in writing English.

  2. Fragmentation of Patient Safety Research: A Critical Reflection of Current Human Factors Approaches to Patient Handover

    PubMed Central

    Manser, Tanja

    2013-01-01

    The integration of human factors science in research and interventions aimed at increased patient safety has led to considerable improvements. However, some challenges to patient safety persist and may require human factors experts to critically reflect upon their predominant approaches to research and improvement. This paper is a call to start a discussion of these issues in the area of patient handover. Briefly reviewing recent handover research shows that while these studies have provided valuable insights into the communication practices for a range of handover situations, the predominant research strategy of studying isolated handover episodes replicates the very problem of fragmentation of care that the studies aim to overcome. Thus, there seems to be a need for a patient-centred approach to handover research that aims to investigate the interdependencies of handover episodes during a series of transitions occurring along the care path. Such an approach may contribute to novel insights and help to increase the effectiveness and sustainability of interventions to improve handover. Significance for public health While much of public health research has a preventive focus, health services research is generally concerned with the ways in which care is provided to those requiring treatment. This paper calls for a patient-centred approach to research on patient handover; a significant contributor to adverse events in healthcare. It is argued that this approach has the potential to improve our understanding of handover processes along the continuum of care. Thus, it can provide a scientific foundation for effective improvements in handover that are likely to reduce patient harm and help to maintain patient safety. PMID:25170504

    Cleland, Deborah; Wyborn, Carina

    2010-12-01

    Critical systems methodology has been advocated as an effective and ethical way to engage with the uncertainty and conflicting values common to ecohealth problems. We use two contrasting case studies, coral reef management in the Philippines and national park management in Australia, to illustrate the value of critical systems approaches in exploring how people respond to environmental threats to their physical and spiritual well-being. In both cases, we used visual methods--participatory modeling and rich picturing, respectively. The critical systems methodology, with its emphasis on reflection, guided an appraisal of the research process. A discussion of these two case studies suggests that visual methods can be usefully applied within a critical systems framework to offer new insights into ecohealth issues across a diverse range of socio-political contexts. With this article, we hope to open up a conversation with other practitioners to expand the use of visual methods in integrated research.

    We demonstrate the possibility of critical coupling through frustrated total internal reflection in a thick plasmonic grating below the first diffraction order. Differently from conventional approaches relying on the excitation of surface plasmon-polaritons, here we exploit the light coupling with the leaky modes supported by the grating. This mechanism entails a wide-angle coupling and effectively access spectral bands that would otherwise be difficult to probe using conventional plasmonic critical coupling techniques, such as the Otto configuration. Our finding may pave the way to efficient plasmonic bio-sensor devices.

  7. Aerosol single-scattering albedo retrieval over North Africa using critical reflectance

    NASA Astrophysics Data System (ADS)

    Wells, Kelley C.

    The sign and magnitude of the aerosol radiative forcing over bright surfaces is highly dependent on the absorbing properties of the aerosol. Thus, the determination of aerosol forcing over desert regions requires accurate information about the aerosol single-scattering albedo (SSA). However, the brightness of desert surfaces complicates the retrieval of aerosol optical properties using passive space-based measurements. The aerosol critical reflectance is one parameter that can be used to relate top-of-atmosphere (TOA) reflectance changes over land to the aerosol absorption properties, without knowledge of the underlying surface properties or aerosol loading. Physically, the parameter represents the TOA reflectance at which increased aerosol scattering due to increased aerosol loading is balanced by increased absorption of the surface contribution to the TOA reflectance. It can be derived by comparing two satellite images with different aerosol loading, assuming that the surface reflectance and background aerosol are similar between the two days. In this work, we explore the utility of the critical reflectance method for routine monitoring of spectral aerosol absorption from space over North Africa, a region that is predominantly impacted by absorbing dust and biomass burning aerosol. We derive the critical reflectance from Moderate Resolution Spectroradiometer (MODIS) Level 1B reflectances in the vicinity of two Aerosol Robotic Network (AERONET) stations: Tamanrasset, a site in the Algerian Sahara, and Banizoumbou, a Sahelian site in Niger. We examine the sensitivity of the critical reflectance parameter to aerosol physical and optical properties, as well as solar and viewing geometry, using the Santa Barbara DISORT Radiative Transfer (SBDART) model, and apply our findings to retrieve SSA from the MODIS critical reflectance values. We compare our results to AERONET-retrieved estimates, as well as to measurements of the TOA albedo and surface fluxes from the

    2010-01-01

    This research uses the critical reflectance technique, a space-based remote sensing method, to measure the spatial distribution of aerosol absorption properties over land. Choosing two regions dominated by biomass burning aerosols, a series of sensitivity studies were undertaken to analyze the potential limitations of this method for the type of aerosol to be encountered in the selected study areas, and to show that the retrieved results are relatively insensitive to uncertainties in the assumptions used in the retrieval of smoke aerosol. The critical reflectance technique is then applied to Moderate Resolution Imaging Spectrometer (MODIS) data to retrieve the spectral aerosol single scattering albedo (SSA) in South African and South American 35 biomass burning events. The retrieved results were validated with collocated Aerosol Robotic Network (AERONET) retrievals. One standard deviation of mean MODIS retrievals match AERONET products to within 0.03, the magnitude of the AERONET uncertainty. The overlap of the two retrievals increases to 88%, allowing for measurement variance in the MODIS retrievals as well. The ensemble average of MODIS-derived SSA for the Amazon forest station is 0.92 at 670 nm, and 0.84-0.89 for the southern African savanna stations. The critical reflectance technique allows evaluation of the spatial variability of SSA, and shows that SSA in South America exhibits higher spatial variation than in South Africa. The accuracy of the retrieved aerosol SSA from MODIS data indicates that this product can help to better understand 44 how aerosols affect the regional and global climate.

  11. Establishing open and critical discourses in the science classroom: Reflecting on initial difficulties

    NASA Astrophysics Data System (ADS)

    Dawson, Vaille M.; Taylor, Peter C.

    1998-09-01

    This paper presents a reflective account of a science teacher’s endeavours to use the referent of critical constructivism to transform her pedagogical practices. The context of her action research was a Year 10 Bioethics unit taught at an independent girls’ school in Perth, Western Australia. Students were provided with opportunities to engage in open and critical discourses; many did, but a few were unwilling to participate in accordance with the teacher’s intentions. We illustrate the disruptive influence of these “dissident” students and explore the reasons for their unwillingness to suspend their disbelief in a new way of knowing (and of being) that involves a radical change in the role of language in the classroom. We conclude with recommendations for epistemological pluralism and the careful use of critical discourse for re-negotiating teaching and learning roles and creating conditions for open discourse to flourish.

    AIDS Drug Assistance Programs in several states already have to put HIV-infected people on waiting lists to receive life-saving antiretroviral drugs because of budget shortfalls, and AIDS advocates say this problem will continue through 2002 and 2003 unless Congress provides a financial boost to HIV programs. Activists also say the United States will never achieve its goal of reducing new HIV infection rates by 50% within the next few years unless prevention spending is increased.

    The continuing obesity epidemic in the USA calls for the examination of antecedents to the well-known risk factors of physical activity and diet. The neighborhood built environment has been extensively studied in relation to obesity noting an increased risk of development and prevalence of obesity in relation to numerous built environment characteristics (lack of green spaces, higher number of fast food restaurants, low walkability indices). The neighborhood social environment, however, has been less extensively studied but is perhaps an equally important component of the neighborhood environment. The neighborhood social environment, particularly constructs of social capital, collective efficacy, and crime, is associated with obesity among both adults and children. Several studies have identified physical activity as a potential pathway of the neighborhood social environment and obesity association. Further work on social networks and norms and residential segregation, as well as the examination of dietary behaviors and mental health as potential mediating pathways, is necessary. Given the existing evidence, intervening on the neighborhood social environment may prove to be an effective target for the prevention on obesity. Intervention studies that promote healthy behaviors and prevent obesity while addressing aspects of the neighborhood social environment are necessary to better identify targets for obesity prevention.

  14. Pressure ulcers: critical considerations in prevention and management.

    PubMed

    Alvarez, O M

    1991-01-01

    Pressure ulcer development is a serious problem occurring predominately among elderly persons, who are confined to bed or chair. Factors associated with pressure ulcer development include: cerebrovascular accident, impaired nutritional intake, fecal incontinence, lymphocytopenia and a high comorbidity score. Implementation of preventative measures, such as: in-depth assessment for mobility, a pressure relieving device combined with adequate repositioning, thorough evaluation for nutritional status and urinary incontinence, significantly reduce pressure ulcer incidence. If the pressure ulcer is a partial thickness (Stage II) wound, the causative factors are probably friction and/or moisture. If the ulcer is full thickness (Stage III, IV) it is secondary to pressure and/or shearing forces. The development of wound infection is the most common complication. Osteomyelitis is not an uncommon occurrence and must be initially ruled out in all full thickness pressure ulcers. Surgical debridement of necrotic tissue is necessary prior to further treatment and /or assessments. Cultures and antibiotic therapy are indicated only upon evidence of infection (erythema, edema, cellulitis, osteomyelitis, leukocytosis, bandemia or fever). Topical pharmacologic agents may be used to prevent or treat infection but must be carefully controlled to avoid such adverse effects as toxicity to the wound, allergic reaction and development of resistant pathogens. Proper use of occlusive dressings increase patient comfort, enhance healing, decrease the possibility of infection, save time and reduce costs. A patient presenting an ulcer which fails to improve, or due to its size will take a great deal of time to heal, should be evaluated for surgical closure.

  15. Critical experiments on single-unit spherical plutonium geometries reflected and moderated by oil

    Experimental critical configurations are reported for several dozen spherical and hemispherical single-unit assemblies of plutonium metal. Most were solid but many were hollow-centered, thick, shell-like geometries. All were constructed of nested plutonium (mostly {sup 2139}Pu) metal hemispherical shells. Three kinds of critical configurations are reported. Two required interpolation and/or extrapolation of data to obtain the critical mass because reflector conditions were essentially infinite. The first finds the plutonium essentially fully reflected by a hydrogen-rich oil; the second is essentially unreflected. The third kind reports the critical oil reflector height above a large plutonium metal assembly of accurately known mass (no interpolation required) when that mass was too great to permit full oil reflection. Some configurations had thicknesses of mild steel just outside the plutonium metal, separating it from the oil. These experiments were performed at the Rocky Flats Critical Mass Laboratory in the late 1960s. They have not been published in a form suitable for benchmark-quality comparisons against state-of-the-art computational techniques until this paper. The age of the data and other factors lead to some difficulty in reconstructing aspects of the program and may, in turn, decrease confidence in certain details. Whenever this is true, the point is acknowledged. The plutonium metal was alpha-phase {sup 239}Pu containing 5.9 wt-% {sup 240}Pu. All assemblies were formed by nesting 1.667-mm-thick (nominal) bare plutonium metal hemispherical shells, also called hemishells, until the desired configuration was achieved. Very small tolerance gaps machined into radial dimensions reduced the effective density a small amount in all cases. Steel components were also nested hemispherical shells; but these were nominally 3.333-mm thick. Oil was used as the reflector because of its chemical compatibility with plutonium metal.

    Critical reflection underpins critical thinking, a highly desirable generic nursing graduate capability. To improve the likelihood of critical thinking transferring to clinical practice, reflective thinking needs to be measured within the learning space of simulation. This study was divided into two phases to address the reliability and validity measures of previously untested surveys. Phase One data was collected from individuals (n = 6) using a 'think aloud' approach and an expert panel to review content validity, and verbatim comment analysis was undertaken. The Reflective Thinking Instrument and Critical Reflection Self-Efficacy Visual Analogue Scale items were contextualised to simulation. The expert review confirmed these instruments exhibited content validity. Phase Two data was collected through an online survey (n = 58). Cronbach's alpha measured internal consistency and was demonstrated by all subscales and the Instrument as a whole (.849). There was a small to medium positive correlation between critical reflection self-efficacy and general self-efficacy (r = .324, n = 56, p = .048). Participant responses were positive regarding the simulation experience. The research findings demonstrated that the Reflective Thinking and Simulation Satisfaction survey is reliable. Further development of this survey to establish validity is recommended to make it viable.

    We present a critical analysis of an alternative technique of point contact Andreev reflection (PCAR) spectroscopy used to extract energy resolved information of superconductors which is based on making 'soft-contacts' between superconductors and indium. This technique is not sensitive to mechanical vibrations and hence can be used in a cryogen free platform increasing its accessibility to users having no access to cryogenic liquids. Through our experiments on large number of superconducting films we show that the PCAR spectra below the T c of In show sub-harmonic gap structures consistent with the theory of multiple Andreev reflection (MAR) and a zero bias conductance (ZBC) anomaly associated with the Josephson supercurrent. Furthermore, we demonstrate that large contact resistance with low transparency ballistic contacts in the PCAR regime are required to obtain reliable spectroscopic data. One limitation of the technique arises for low contact resistance junctions where the superconducting proximity effect (SPE) reduces the value of the superconducting energy gap.

    The baseline design for space nuclear power is a fission surface power (FSP) system: sodium-potassium (NaK) cooled, fast spectrum reactor with highly-enriched-uranium (HEU)-O2 fuel, stainless steel (SS) cladding, and beryllium reflectors with B4C control drums. Previous studies were performed to evaluate modeling capabilities and quantify uncertainties and biases associated with analysis methods and nuclear data. Comparison of Zero Power Plutonium Reactor (ZPPR)-20 benchmark experiments with the FSP design indicated that further reduction of the total design model uncertainty requires the reduction in uncertainties pertaining to beryllium and uranium cross-section data. Further comparison with three beryllium-reflected HEU-metal benchmark experiments performed at the Oak Ridge Critical Experiments Facility (ORCEF) concluded the requirement that experimental validation data have similar cross section sensitivities to those found in the FSP design. A series of critical experiments was performed at ORCEF in the 1960s to support the Medium Power Reactor Experiment (MPRE) space reactor design. The small, compact critical assembly (SCCA) experiments were graphite- or beryllium-reflected assemblies of SS-clad, HEU-O2 fuel on a vertical lift machine. All five configurations were evaluated as benchmarks. Two of the five configurations were beryllium reflected, and further evaluated using the sensitivity and uncertainty analysis capabilities of SCALE 6.1. Validation of the example FSP design model was successful in reducing the primary uncertainty constituent, the Be(n,n) reaction, from 0.28 %dk/k to 0.0004 %dk/k. Further assessment of additional reactor physics measurements performed on the SCCA experiments may serve to further validate FSP design and operation.

    A zero-power critical assembly was designed, constructed, and operated for the purpose of conducting a series of benchmark experiments dealing with the physics characteristics of a UN-fueled, Li-7 cooled, Mo-reflected, drum-controlled compact fast reactor for use with a space-power electric conversion system. The experimental program consisted basically of measuring the differential neutron spectra and the changes in critical mass that accompanied the stepwise addition of (Li-7)3N, Hf, Ta, and W to a basic core fueled with U metal in a pin-type Ta honeycomb structure. In addition, experimental results were obtained on power distributions, control characteristics, neutron lifetime, and reactivity worths of numerous absorber, structural, and scattering materials.

    Ex situ conservation tools, such as captive breeding for reintroduction, are considered last resort to help recover threatened or endangered species. However, they may also provide alternative strategies where reducing threats directly is difficult or ineffective. Headstarting, or captive rearing of eggs or neonate animals and subsequent release into the wild, has been controversial for decades. A major criticism is that headstarting is a symptomatic treatment of conservation problems (halfway technology), however, it may provide a mechanism to address multiple threats, particularly in close proximity of population centres. Here we conduct Population Viability Analyses (PVA) to assess the risk of extinction of Australia's most widespread freshwater turtle, Chelodina longicollis, to increasing adult road mortality and reduced recruitment through nest predation from introduced foxes. We also model a range of management scenarios to test the effectiveness of headstarting, fox management, and measures that reduce adult road mortality. We show that headstarting should be a primary tool for managing freshwater turtles under threats that affect multiple life history stages. Headstarting from harvest populations were the only scenarios that eliminated all risks of extinction, while also maintaining population growth. Small increments in adult mortality have greatest effect on population growth and extinction risk, however, where threats simultaneously affect other life history stages (e.g.. recruitment), eliminating harvest pressures on adult females alone will not eliminate the risk of population extinction. In our models, one harvest population could supply enough hatchlings to supplement 25 other similar sized populations at an annual rate to maintain population growth and eliminate the risk of population extinction. We advocate the creation of harvest populations for managing freshwater turtles facing significant threats to multiple life history stages. This article is

    Despite implementation of CDC recommendations and bundled interventions for preventing catheter-associated blood stream infection, ventilator-associated pneumonia, or urinary catheter–associated infections, nosocomial infections and sepsis remain a significant cause of morbidity and mortality in critically ill children. Recent studies suggest that acquired critical illness stress-induced immune suppression (CRISIS) plays a role in the development of nosocomial infection and sepsis. This condition can be related to inadequate zinc, selenium, and glutamine levels, as well as hypoprolactinemia, leading to stress-induced lymphopenia, a predominant TH2 monocyte/macrophage state, and subsequent immune suppression. Prolonged immune dysfunction increases the likelihood of nosocomial infections associated with invasive devices. Although strategies to prevent common complications of critical illness are routinely employed (eg, prophylaxis for gastrointestinal bleeding, thrombophlebitis), no prophylactic strategy is used to prevent stress-induced immune suppression. This is the authors’ rationale for the pediatric CRISIS prevention trial (NCT00395161), designed as a randomized, double-blind, controlled clinical investigation to determine if daily enteral supplementation with zinc, selenium, and glutamine as well as parenteral metoclopramide (a dopamine 2 receptor antagonist that reverses hypoprolactinemia) prolongs the time until onset of nosocomial infection or sepsis in critically ill children compared to enteral supplementation with whey protein. If effective, this combined nutritional and pharmacologic approach may lessen the excess morbidity and mortality as well as resource utilization associated with nosocomial infections and sepsis in this population. The authors present the design and analytic plan for the CRISIS prevention trial. PMID:19380753

    1996-03-01

    This paper, written by two male nurse teachers, describes and analyses their experience of working in a nurse education culture permeated by the philosophy of business management. The introduction of business management practices to nurse education is discussed as a reflection of the current political hegemony of market forces and individualism. The authors discuss the implications for nurse teachers of being continually exposed to these politically motivated forces which increasingly provide the paradigm for service developments within the United Kingdom health services. In discussing the impact of this exposure it is argued that at the personal level individual teachers are experiencing a degree of apathy and personal dissonance which undermines their professional value system, resulting in emotional distress and a crisis of identity. It provides a critical reflection on the way organizational dynamics and power relations influence the subjective sense-making of individuals. The authors use a multiplicity of perspectives, including those provided by individual psychology, power relations, feminism and personhood, to argue for the need to develop an alternative paradigm which is characterized by the valuing of individual persons, empathic sensitivity and the fostering of creativity.

    A considerable number of studies have sought to identify what factors accounted for substantial reductions in HIV seroprevalence after several countries deployed "ABC" (abstinence, be faithful, condom use) strategies. After much public discourse and research on ABC success stories, the Joint United Nations Programme on HIV/AIDS 2004 epidemic report indicated that nearly 50% of infected people worldwide were women, up from 35% in 1985. In light of the feminization of HIV/AIDS, we critically assess the limitations of ABC strategies. We provide 3 additional prevention strategies that focus on gender relations, economics, and migration (GEM) and can speak to the new face of the epidemic. Pressing beyond ABC, GEM strategies provide the basis for a stronger central platform from which national efforts against HIV/AIDS can proceed to reduce transmission risks.

    Aerosols are tiny suspended particles in the atmosphere that scatter and absorb sunlight. Smoke particles are aerosols, as are sea salt, particulate pollution and airborne dust. When you look down at the earth from space sometimes you can see vast palls of whitish smoke or brownish dust being transported by winds. The reason that you can see these aerosols is because they are reflecting incoming sunlight back to the view in space. The reason for the difference in color between the different types of aerosol is that the particles arc also absorbing sunlight at different wavelengths. Dust appears brownish or reddish because it absorbs light in the blue wavelengths and scatters more reddish light to space, Knowing how much light is scattered versus how much is absorbed, and knowin that as a function of wavelength is essential to being able to quantify the role aerosols play in the energy balance of the earth and in climate change. It is not easy measuring the absorption properties of aerosols when they are suspended in the atmosphere. People have been doing this one substance at a time in the laboratory, but substances mix when they are in the atmosphere and the net absorption effect of all the particles in a column of air is a goal of remote sensing that has not yet been completely successful. In this paper we use a technique based on observing the point at which aerosols change from brightening the surface beneath to darkening it. If aerosols brighten a surface. they must scatter more light to space. If they darken the surface. they must be absorbing more. That cross over point is called the critical reflectance and in this paper we show that critical reflectance is a monotonic function of the intrinsic absorption properties of the particles. This parameter we call the single scattering albedo. We apply the technique to MODIS imagery over the Sahara and Sahel regions to retrieve the single scattering albedo in seven wavelengths, compare these retrievals to ground

    Reflection is an essential component of teacher-development programs, and reliable, valid methods to teach, assess, and evaluate reflection are critical. However, it is important that appropriate methods are created for and evaluated across multiple disciplinary backgrounds, as the participants' backgrounds are a major factor in the development of critical reflection. The patchwork-text approach is a narrative process that is predominantly focused on the personal development of the individual. The current study used the patchwork-text approach for the development of reflection in participants with a science background who had not used a reflective approach for personal development before. Twenty summative essays and 103 formative essays from 21 participants who underwent a 1-year higher-education teacher-development program were analyzed to assess whether the quality and quantity of reflective writing was enhanced through a regular, iterative process of reflective writing with feedback. The analysis of the essays involved the use of a predefined set of criteria for identifying the different reflective levels from 1 to 4 and the calculation of a reflective score to evaluate the overall development. The results show a clear improvement of higher-level critical thinking as the participants progressed through their course. Higher levels of reflection were achieved particularly where a unit focused on a familiar area for the participant as opposed to one in which the participant had less experience. The analysis provides evidence that the patchwork text is a useful method for development and evaluation of reflection in participants with a veterinary/animal-science base.

    Rowicki, Mark Adam

    This study examined the role of reflective journal writing on the development of critical thinking in seventh grade integrated science students. The students participating in this study were part of four science classes taught by the same instructor, using the same curriculum and methods employed during this study. The larger working group consisted of 69 seventh grade students who were allowed to participate in this study by virtue of a signed consent form. The 12 students who comprised the smaller writing group were selected from the larger working group. The smaller, criterion-based writing group was selected from the working group based on their level of critical thinking as indicated on the pre-test instrument. The study utilized several methods of data collection. Data were collected through analyses of student journal entries, class discussions, and a pre and posttest instrument to measure a student's level of critical thinking. All participants were given code names to mask their identity. The findings of this study indicate that a majority of the students' ability to think critically appeared to improve after 18 weeks of reflective journal writing. However, no relationship was found between a student's level of critical thinking and his or her ability to write reflectively. Although many participants did improve their level of reflective writing and critical thinking, there was no direct relationship found between the two skills. This study provided some evidence that reflective journal writing is beneficial for students although some benefits may be intangible. The attitudes of many students toward writing improved, and there was a noticeable increase in students' willingness to share their thoughts and respond to questions in class. Practice in reflective writing also contributed to improved writing skills by the participants. Additionally, there are five recommendations for further research derived from this study.

    2016-01-01

    Despite standard fall precautions, including nonskid socks, signs, alarms, and patient instructions, our 48-bed cardiac intermediate care unit (CICU) had a 41% increase in the rate of falls (from 2.2 to 3.1 per 1,000 patient days) and a 65% increase in the rate of falls with injury (from 0.75 to 1.24 per 1,000 patient days) between fiscal years (FY) 2012 and 2013. An evaluation of the falls data conducted by a cohort of four clinical nurses found that the majority of falls occurred when patients were unassisted by nurses, most often during toileting. Supported by the leadership team, the clinical nurses developed an accountability care program that required nurses to use reflective practice to evaluate each fall, including sending an e-mail to all staff members with both the nurse's and the patient's perspective on the fall, as well as the nurse's reflection on what could have been done to prevent the fall. Other program components were a postfall huddle and guidelines for assisting and remaining with fall risk patients for the duration of their toileting. Placing the accountability for falls with the nurse resulted in decreases in the unit's rates of falls and falls with injury of 55% (from 3.1 to 1.39 per 1,000 patient days) and 72% (from 1.24 to 0.35 per 1,000 patient days), respectively, between FY2013 and FY2014. Prompt call bell response (less than 60 seconds) also contributed to the goal of fall prevention.

    Ventilator-associated pneumonia (VAP) is a hospital-acquired pneumonia that occurs in patients usually 48 hours or more after mechanical ventilator intubation. VAP is the most common nosocomial infection in critically ill patients. Mechanical ventilators are critical oxygenation and ventilation systems for patients. However, there is a close relationship among self-use efficacy, system settings, and VAP infection rate. VAP not only results in higher mortality, longer hospital stays, and higher medical costs, but also negatively affects patient outcomes and medical care quality. The purpose of this article was to provide reference information on VAP risk factors and prevention measures.

  5. Study of neutron noise from reflected, metal assemblies with criticality safety applications in mind

    SciTech Connect

    Barnett, C.S.

    1985-08-20

    The author studied the statistics of detected neutrons that leaked from four subcritical reflected, enriched-uranium assemblies, to explore the feasibility of developing a criticality warning system based on neutron noise analysis. The calculated multiplication factors of the assemblies are 0.59, 0.74, 0.82, and 0.92. The author studied three possible discriminators, i.e., three signatures that might be used to discriminate among assemblies of various multiplications. They are: (1) variance-to-mean ratio of the counts in a time bin (V/M); (2) covariance-to-mean ratio of the counts in a common time bin from two different detectors (C/M); and (3) covariance-to-mean ratio of the counts from a single detector in two adjacent time bins of equal length, which the author calls the serial-covariance-to-mean ratio (SC/M). The performances of the three discriminators were not greatly different, but a hierarchy did emerge: SC/M greater than or equal to V/M greater than or equal to C/M. An example of some results: in the neighborhood of k = 0.6 the ..delta..k required for satisfactory discrimination varies from about 3% to 7% as detector solid angle varies from 19% to 5%. In the neighborhood of k = 0.8 the corresponding ..delta..ks are 1% and 2%. The noise analysis techniques studied performed well enough in deeply subcritical situations to deserve testing in an applications environment. They have a good chance of detecting changes in reactivity that are potentially dangerous. One can expect sharpest results when doing comparisons, i.e., when comparing two records, one taken in the past under circumstances known to be normal and one taken now to search for change.

  6. Validation of Safety-Critical Systems for Aircraft Loss-of-Control Prevention and Recovery

    NASA Technical Reports Server (NTRS)

    Belcastro, Christine M.

    2012-01-01

    Validation of technologies developed for loss of control (LOC) prevention and recovery poses significant challenges. Aircraft LOC can result from a wide spectrum of hazards, often occurring in combination, which cannot be fully replicated during evaluation. Technologies developed for LOC prevention and recovery must therefore be effective under a wide variety of hazardous and uncertain conditions, and the validation framework must provide some measure of assurance that the new vehicle safety technologies do no harm (i.e., that they themselves do not introduce new safety risks). This paper summarizes a proposed validation framework for safety-critical systems, provides an overview of validation methods and tools developed by NASA to date within the Vehicle Systems Safety Project, and develops a preliminary set of test scenarios for the validation of technologies for LOC prevention and recovery

    Arguments are presented for studying soft diffractive physics at anti p-p colliders in terms of Critical Pomeron Reggeon Field Theory. It is emphasized that both confinement and chiral-symmetry breaking play a vital role in the occurrence of the Critical Pomeron in QCD. SU(3) is the unique strong-interaction gauge group giving the Critical Pomeron and the maximum number of quarks allowed by asymptotic freedom is required for criticality.

  9. Chronic caffeine treatment prevents stress-induced LTP impairment: the critical role of phosphorylated CaMKII and BDNF.

    PubMed

    Alzoubi, K H; Srivareerat, M; Aleisa, A M; Alkadhi, K A

    2013-01-01

    Caffeine has been reported to enhance cognition in animal and humans. Additionally, caffeine alleviates cognitive impairment associated with a number of disorders including Alzheimer's disease. The lipophilic nature of caffeine allows for rapid absorption into the bloodstream where it freely crosses the blood-brain barrier. Caffeine promotes dendritic spine growth in cultured hippocampal neurons, which suggests a neuroprotective effect. We examined the effect of chronic caffeine treatment on stress-induced suppression of long-term potentiation (LTP) and impairment of molecules of its signaling cascade. Rats were subjected to daily stress using the psychosocial stress paradigm (intruder model), in vivo recordings from area CA1 of the hippocampus of adult rat, and immunoblot analysis of essential signaling molecules. Caffeine prevented stress-induced LTP impairment. Western blot analysis showed reduction of the basal levels of the phosphorylated calcium calmodulin kinase II (P-CAMKII), total CaMKII, and brain-derived neurotrophic factor (BDNF) in area CA1 of stressed rats. These reductions were prevented by chronic caffeine treatment (0.33 mg/L in drinking water). In addition, caffeine prevented the upregulation of calcineurin levels in stressed rats. High-frequency stimulation (HFS) normally increased P-CaMKII, total CaMKII, and calcineurin levels in control as well as in caffeine-treated stressed rats. However, in stressed rats, the same HFS induced increases in the levels of total CaMKII and calcineurin, but not those of P-CaMKII. The levels of signaling molecules may not reflect activities of these molecules. It appears that the neuroprotective effect of caffeine involves preservation of the levels of essential kinases and phosphatases in stressed rats. This may include preservation of basal levels of BDNF by chronic caffeine treatment in stressed animals. These findings highlight the critical role of P-CaMKII and BDNF in caffeine-induced prevention of stress

  10. The mature minor: some critical psychological reflections on the empirical bases.

    PubMed

    Partridge, Brian C

    2013-06-01

    Moral and legal notions engaged in clinical ethics should not only possess analytic clarity but a sound basis in empirical findings. The latter condition brings into question the expansion of the mature minor exception. The mature minor exception in the healthcare law of the United States has served to enable those under the legal age to consent to medical treatment. Although originally developed primarily for minors in emergency or quasi-emergency need for health care, it was expanded especially from the 1970s in order to cover unemancipated minors older than 14 years. This expansion initially appeared plausible, given psychological data that showed the intellectual capacity of minors over 14 to recognize the causal connection between their choices and the consequences of their choices. However, subsequent psychological studies have shown that minors generally fail to have realistic affective and evaluative appreciations of the consequences of their decisions, because they tend to over-emphasize short-term benefits and underestimate long-term risks. Also, unlike most decisionmakers over 21, the decisions of minors are more often marked by the lack of adequate impulse control, all of which is reflected in the far higher involvement of adolescents in acts of violence, intentional injury, and serious automobile accidents. These effects are more evident in circumstances that elicit elevated affective responses. The advent of brain imaging has allowed the actual visualization of qualitative differences between how minors versus persons over the age of 21 generally assess risks and benefits and make decisions. In the case of most under the age of 21, subcortical systems fail adequately to be checked by the prefrontal systems that are involved in adult executive decisions. The neuroanatomical and psychological model developed by Casey, Jones, and Summerville offers an empirical insight into the qualitative differences in the neuroanatomical and neuropsychological bases

  12. Electrical muscle stimulation prevents critical illness polyneuromyopathy: a randomized parallel intervention trial

    PubMed Central

    2010-01-01

    Introduction Critical illness polyneuromyopathy (CIPNM) is a common complication of critical illness presenting with muscle weakness and is associated with increased duration of mechanical ventilation and weaning period. No preventive tool and no specific treatment have been proposed so far for CIPNM. Electrical muscle stimulation (EMS) has been shown to be beneficial in patients with severe chronic heart failure and chronic obstructive pulmonary disease. Aim of our study was to assess the efficacy of EMS in preventing CIPNM in critically ill patients. Methods One hundred and forty consecutive critically ill patients with an APACHE II score ≥ 13 were randomly assigned after stratification to the EMS group (n = 68) (age:61 ± 19 years) (APACHE II:18 ± 4, SOFA:9 ± 3) or to the control group (n = 72) (age:58 ± 18 years) (APACHE II:18 ± 5, SOFA:9 ± 3). Patients of the EMS group received daily EMS sessions. CIPNM was diagnosed clinically with the medical research council (MRC) scale for muscle strength (maximum score 60, <48/60 cut off for diagnosis) by two unblinded independent investigators. Duration of weaning from mechanical ventilation and intensive care unit (ICU) stay were recorded. Results Fifty two patients could be finally evaluated with MRC; 24 in the EMS group and 28 in the control group. CIPNM was diagnosed in 3 patients in the EMS group as compared to 11 patients in the control group (OR = 0.22; CI: 0.05 to 0.92, P = 0.04). The MRC score was significantly higher in patients of the EMS group as compared to the control group [58 (33 to 60) vs. 52 (2 to 60) respectively, median (range), P = 0.04). The weaning period was statistically significantly shorter in patients of the EMS group vs. the control group [1 (0 to 10) days vs. 3 (0 to 44) days, respectively, median (range), P = 0.003]. Conclusions This study suggests that daily EMS sessions prevent the development of CIPNM in critically ill patients and also result in shorter duration of weaning

  13. Thinking and meddling with boundaries: Critical reflections on Matthew Weinstein's narrative of street medics, red-zones and glop

    NASA Astrophysics Data System (ADS)

    Alsop, Steve

    2015-03-01

    In pursuit of more mindful notions of hybridity, this review essay provides a series of reflections on Mathew Weinstein's representations of Street Medics and `sciences for the red zones of neoliberalism'. My analysis draws on three popular ways of thinking with boundaries to offer a critical reading of the boundary-work that the essay performs with respect to three dialectics: (1) technical and political; (2) disciplinarily and multidisciplinarities; and (3) structures and agencies. I conclude with reflections on my boundary labour as a researcher, writer and pedagogue and how such cultural work might learn to live better with difference, ambiguities, hybrids and cross-hybrid learning.

  14. Critical reflections on the role of CBPR within an RCT community health worker prevention intervention.

    PubMed

    Rosenthal, E Lee; Balcazar, Hector G; De Heer, Hendrik D; Wise, Sherrie; Flores, Leticia; Aguirre, Melissa

    2014-01-01

    Coalescence of culturally relevant and community-based research with traditional scientific inquiry is necessary for the translation of science into practice. One methodology that has been identified as an important missing link in achieving the goal of combining science and community practice is the community-based participatory research approach, or CBPR. To demonstrate how CBPR has been successfully blended with randomized control trial (RCT) methodology, we showcase a randomized community trial that has shown efficacy in reducing cardiovascular risk factors integrating community health workers. The purpose of this article is 2-fold. First, it describes the process of merging the CBPR approach within an RCT framework and, second, it describes lessons learned in conducting CBPR-RCT research initiatives.

  16. Evaluating chemical effects on mammary gland development: A critical need in disease prevention.

    PubMed

    Osborne, Gwendolyn; Rudel, Ruthann; Schwarzman, Megan

    2015-07-01

    Although understanding the environmental factors that contribute to breast cancer could improve disease prevention, standard chemical testing protocols do not adequately evaluate chemicals' effects on breast development. Evidence suggests: (1) mammary gland (MG) development is a complex process that extends from gestation through fetal and neonatal growth, puberty, and pregnancy; (2) altered MG development can increase the risk of breast cancer and other adverse outcomes; and (3) chemical exposures during susceptible windows of development may alter the MG in ways that increase risk for later disease. Together, these highlight the need to better understand the complex relationship between exposure to endocrine disrupting compounds (EDCs) and the alterations in MG morphology and gene expression that ultimately increase disease risk. Changing guideline toxicity testing studies to incorporate perinatal exposures and MG whole mounts would generate critical knowledge about the effects of EDCs on the MG and could ultimately inform disease prevention.

  17. Does the use of reflective models restrict critical thinking and therefore learning in nurse education? What have we done?

    PubMed

    Coward, Melaine

    2011-11-01

    This article will explore relevant publications relating to practices involving the use of reflective models in UK nurse education. This will then be critically analysed in terms of my personal experiences as a nurse educator. SchÖn's seminal work (1987) on reflection never intended for the process of reflection to become so structured that it actually restricted thinking. Sadly however, it is my personal belief that this is the case within some aspects of nurse education, primarily due to the introduction and overuse of structured models of reflection. A large part of written assessment in nurse education utilises reflective writing, this may not be helpful in terms of learning and exploration of practice experiences. Indeed these models are now being seen by both students and some nurse educators as compulsory. The number of these models available to students within nurse education is phenomenal (Rolfe et al., 2001) and they appear to be a requirement for educators to support their learners in constructing ways of thinking. Further consideration needs to be given by nurses educators to the underpinning philosophy and concepts relating to reflection.

  18. Activation of dopamine neurons is critical for aversive conditioning and prevention of generalized anxiety.

    PubMed

    Zweifel, Larry S; Fadok, Jonathan P; Argilli, Emmanuela; Garelick, Michael G; Jones, Graham L; Dickerson, Tavis M K; Allen, James M; Mizumori, Sheri J Y; Bonci, Antonello; Palmiter, Richard D

    2011-05-01

    Generalized anxiety is thought to result, in part, from impairments in contingency awareness during conditioning to cues that predict aversive or fearful outcomes. Dopamine neurons of the ventral midbrain exhibit heterogeneous responses to aversive stimuli that are thought to provide a critical modulatory signal to facilitate orientation to environmental changes and assignment of motivational value to unexpected events. Here we describe a mouse model in which activation of dopamine neurons in response to an aversive stimulus is attenuated by conditional genetic inactivation of functional NMDA receptors on dopamine neurons. We discovered that altering the magnitude of excitatory responses by dopamine neurons in response to an aversive stimulus was associated with impaired conditioning to a cue that predicts an aversive outcome. Impaired conditioning by these mice was associated with the development of a persistent, generalized anxiety-like phenotype. These data are consistent with a role for dopamine in facilitating contingency awareness that is critical for the prevention of generalized anxiety.

  8. From protective intelligence to threat assessment: Strategies critical to preventing targeted violence and the active shooter.

    PubMed

    Doherty, Matthew

    Acts of targeted violence - including active shooter incidents - are typically over within 15 minutes, often before the first law enforcement personnel can respond to the scene. More than a third of active shooter incidents in the USA, for example, last less than five minutes. While this stark fact is often used, with unimpeachable validity, as the cornerstone of employee security awareness training and the need for each employee to make a quick decision on whether to run, hide or fight, it also underscores the importance of another critical priority: prevention. This paper focuses on several of the most effective strategies and tactics - increasingly used across the USA, but applicable all over the world - in preventing an act of targeted violence or active shooter event. It starts with a brief discussion of the common roadblocks to prevention within enterprises today as well as the warning signs that can reveal an individual's path toward an act of violence. Next, it defines targeted violence and summarises patterns that research has helped uncover with respect to attackers' backgrounds, motives and target selection. This paper also outlines the crucial role played by protective intelligence and threat assessment protocols and provides several case studies to illustrate key concepts in real-world applications. Finally, this discussion points to several emerging trends in the USA and Europe, among other regions - such as radicalisation within the workforce - that are likely to continue to mature in 2016 and the years ahead.

  3. Theory before practice: implicit assumptions about clinical nursing education in Australia as revealed through a shared critical reflection.

    PubMed

    Grealish, Laurie; Smale, Lacey Anne

    2011-08-01

    The transfer of nursing education into the higher education sector occurred over a 10-year period in Australia (1985-1994). Australian nurse leaders settled on a single outcome measure to be applied for all nursing graduates in the form of national competency standards. While this move enabled diversity, the lack of consistency in curriculum design has subsequently led to increasing confusion for clinicians who support students' learning in clinical placements. Using a shared critical reflection method, the authors reviewed (1) the evaluation comments from nurses in one nursing unit of a hospital in one Australian jurisdiction and (2) an historical review of nursing literature at the time of the transfer of nursing education into the higher education sector. The reflection suggests that the aim of the transfer, to create critical thinking graduates, has been undermined by the implicit clinical education practices that have since emerged. In order to address the contemporary challenges for clinical staff working with students from multiple universities, as well as increased student numbers to address the nursing shortage, we recommend a new approach to curriculum design: a national clinical curriculum drawn from social, as well as cognitive, learning theory that at once informs clinicians of students' potential abilities and provides the scope to accommodate the increasingly difficult and critical learning requirements of tertiary-based nursing students.

  4. (De)colonizing culture in community psychology: reflections from critical social science.

    Since its inception, community psychology has been interested in cultural matters relating to issues of diversity and marginalization. However, the field has tended to understand culture as static social markers or as the background for understanding group differences. In this article the authors contend that culture is inseparable from who we are and what we do as social beings. Moreover, culture is continually shaped by socio-historical and political processes intertwined within the globalized history of power. The authors propose a decolonizing standpoint grounded in critical social science to disrupt understandings of cultural matters that marginalize others. This standpoint would move the field toward deeper critical thinking, reflexivity and emancipatory action. The authors present their work to illustrate how they integrate a decolonizing standpoint to community psychology research and teaching. They conclude that community psychology must aim towards intercultural work engaging its political nature from a place of ontological/epistemological/methodological parity.

    Faculty in a medical-surgical nursing course developed learning outcomes to foster critical thinking skills involved in clinical reasoning. To facilitate students' abilities to make effective clinical judgments, direct teaching of thinking skills was incorporated into nursing content instruction. This instructional design challenged faculty to develop test items that would permit direct observation of students' thought processes. The author describes how context-dependent item sets were developed to meet this evaluation need.

    Intrahospital transportation of critically ill patients is associated with significant complications. In order to reduce overall risk to the patient, such transports should well organized, efficient, and accompanied by the proper monitoring, equipment, and personnel. Protocols and guidelines for patient transfers should be utilized universally across all healthcare facilities. Care delivered during transport and at the site of diagnostic testing or procedure should be equivalent to the level of care provided in the originating environment. Here we review the most common problems encountered during transport in the hospital setting, including various associated adverse outcomes. Our objective is to make medical practitioners, nurses, and ancillary health care personnel more aware of the potential for various complications that may occur during patient movement from the intensive care unit to other locations within a healthcare facility, focusing on risk reduction and preventive strategies.

    We study the optical response of an attenuated total reflection (ATR) structure in Otto configuration with graphene sheet, paying especial attention to the occurrence of total absorption. Our results show that due to excitation of surface plasmons on the graphene sheet, two different conditions of total absorption may occur. At these conditions, the energy loss of the surface plasmon by radiation is equal to its energy loss by absorption into the graphene sheet. We give necessary conditions on ATR parameters for the existence of total absorption.

    This paper reflects on the historical development of orthogonal acceleration time-of-flight analyzers that have been used routinely for high sensitivity analyses of biological molecules for more than a decade. In particular, the role of the late Michael Guilhaus from the University of New South Wales in Australia is highlighted. This account shows that like most advances in science, successful commercialization of new technology is not straightforward and is often the result of critical contributions of different people and organizations at different points in time.

    This paper aims to provide a critical reflection of the process of consultation offered by a child and adolescent mental health service (CAMHS) to a health visiting team. The consultation process followed two days of training in the Solihull Approach and took place over five 90-minute sessions at six-weekly intervals. In this paper, the Solihull Approach is used as a framework for understanding the consultation process, and the concepts of containment and reciprocity are explored within this context. The challenges and successes of the process are shared and the importance of providing a containing space for frontline practitioners is highlighted.

  10. The benefits of a critical stance: a reflection on past papers on the theories of reasoned action and planned behaviour.

    2011-09-01

    In this paper, I reflect on past papers published in the British Journal of Social Psychology (BJSP) that have played a role in the development of the theory of reasoned action (TRA) and the theory of planned behaviour (TPB). I focus on seven papers that fall into five categories: (1) those that critique the TRA/TPB for taking insufficient account of social factors; (2) those that critique the models on the grounds that many social behaviours are 'habitual'; (3) those that critically examine the construct of perceived behavioural control; (4) those that argue for the importance of affective factors, which appear to be overlooked in the TRA/TPB; and (5) those that argue for the importance of studying the role of moderating factors and interaction effects in the TRA/TPB. I conclude that BJSP's traditional focus on criticism and theory development is one that benefits the journal and the field.

    This philosophical analysis critically explores an archeology of militarism as an underpinning to multiple forms of violence, especially war. Deconstructing militarism and its discourses reveal it as a pervasive geographical, cultural, political, and psychological presence. New war technologies, related health and environmental problems, injuries, social suffering, and disproportionality in military spending as a threat to health are uncovered. Continuing the dialogue in formal nursing associations, critiquing media complicity in securing consent for war, and reconstructing a nonviolent, healthier world through nonviolent resistance are advocated.

    2017-03-22

    Care ethics as initiated by Gilligan, Held, Tronto and others (in the nineteen eighties and nineties) has from its onset been critical towards ethical concepts established in modernity, like 'autonomy', alternatively proposing to think from within relationships and to pay attention to power. In this article the question is raised whether renewal in this same critical vein is necessary and possible as late modern circumstances require rethinking the care ethical inquiry. Two late modern realities that invite to rethink care ethics are complexity and precariousness. Late modern organizations, like the general hospital, codetermined by various (control-, information-, safety-, accountability-) systems are characterized by complexity and the need for complexity reduction, both permeating care practices. By means of a heuristic use of the concept of precariousness, taken as the installment of uncertainty, it is shown that relations and power in late modern care organizations have changed, precluding the use of a straightforward domination idea of power. In the final section a proposition is made how to rethink the care ethical inquiry in order to take late modern circumstances into account: inquiry should always be related to the concerns of people and practitioners from within care practices.

  13. Critical Reexamination of Resonant Soft X-Ray Bragg Forbidden Reflections in Magnetite

    Magnetite, Fe{sub 3}O{sub 4}, displays a highly complex low-temperature crystal structure that may be charge and orbitally ordered. Many of the recent experimental claims of such ordering rely on resonant soft x-ray diffraction at the oxygen K and iron L edges. We have reexamined this system and undertaken soft x-ray diffraction experiments on a high-quality single crystal. Contrary to previous claims in the literature, we show that the intensity observed at the Bragg forbidden (001/2){sub c} reflection can be explained purely in terms of the low-temperature structural displacements around the resonant atoms. This does not necessarily mean that magnetite is not charge or orbitally ordered but rather that the present sensitivity of resonant soft x-ray experiments does not allow conclusive demonstration of such ordering.

    Realist review has increased in popularity as a methodology for complex intervention assessment. Our experience suggests that the process of designing a realist review requires its customization to areas under investigation. To elaborate on this idea, we first describe the logic underpinning realist review and then present critical reflections on our application experience, organized in seven areas. These are the following: (1) the challenge of identifying middle range theory; (2) addressing heterogeneity and lack of conceptual clarity; (3) the challenge of appraising the quality of complex evidence; (4) the relevance of capturing unintended outcomes; (5) understanding the process of context, mechanism, and outcome (CMO) configuring; (6) incorporating middle-range theory in the CMO configuration process; and (7) using middle range theory to advance the conceptualization of outcomes - both visible and seemingly 'hidden'. One conclusion from our experience is that the degree of heterogeneity of the evidence base will determine whether theory can drive the development of review protocols from the outset, or will follow only after an intense period of data immersion. We hope that presenting a critical reflection on customizing realist review will convey how the methodology can be tailored to the often complex and idiosyncratic features of health research, leading to innovative evidence syntheses.

  15. Making space for belonging: critical reflections on the implementation of personalised adult social care under the veil of meaningful inclusion.

    PubMed

    Power, Andrew

    2013-07-01

    This paper critically reflects on the way in which recent adult social care reform has been evolving beneath the alleged policy goal of prioritising the cultivation of meaningful inclusion and 'belonging' in the community. With this goal, there has been a focus away from 'services' for persons with intellectual disabilities, to supporting natural connections within the community. This paper draws on a grounded theory study of the perspectives of those responsible for overseeing community living arrangements for persons with disabilities, drawing on interviews and focus groups with service providers and relevant government officials. It examines the socio-spatial implications of the gradual shift towards 'belonging' as a disability policy goal, as it has evolved in two discrete settings - British Columbia, Canada and Ireland. The findings identify the complexities involved in facilitating active community connection for persons with intellectual disabilities and reveal important cautionary lessons for other jurisdictions where community living policy has arguably been moving away from communal services towards self-managed supports in 'real' communities through personal budgets in an effort to remove barriers to participation. The paper thus critically reflects on the rapid pursuit for transformation in personalised adult social care in government policy, arguing that the process of fostering meaningful community inclusion will and should take time.

    Brunero, S J; Jeon, Y H; Foster, K

    2015-09-01

    This paper discusses the development of a mental health nurse clinician to a mental health nurse researcher. Understanding the theoretical and professional drives that shape mental health nurses clinical practice and how that links to becoming a researcher is discussed. Mental health nurses who conduct research have to often move between their clinical roles and that of the researcher, doing this safely using a reflective supervision approach enables the nurse to conduct the research from a stronger professional and ethical standpoint. The intention of the paper is to encourage mental health nurses to engage in research and development. Shifting between the positions of a mental health nurse clinician and a qualitative researcher has some parallels to the processes in the nurse-service user relationship. This paper addresses this development from practitioner to researcher in one mental health nurse's journey through a PhD study using constructivist grounded theory. The paper examines theoretical and professional drives that have shaped my clinical practice and the role of the researcher in constructivist grounded theory, the notion of the researcher shifting between insider and outsider status, and the importance of reflexivity in conducting research. These influences will be discussed in the context of the development of a constructivist grounded theory study of the delivery of health care to service users with a mental illness in general hospital wards.

    2017-02-01

    This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science (NOS) of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers (PSSTs) specializing in physics and chemistry. The approach was explicit and reflective. Three research questions were posed: (1) What conceptions of NOS do the PSSTs show after a first reflective reading of the historical controversy?, (2) What role is played by the PSSTs' whole class critical discussion of their first reflections on the aspects of NOS dealt with in the controversy?, and (3) What changes are there in the PSSTs' conceptions of NOS after concluding the activity? The data for analysis was extracted from the PSSTs' group reports submitted at the end of the activity and the audio-recorded information from the whole class discussion. A rubric was prepared to assess this data by a process of inter-rater analysis. The results showed overall improvement in understanding the aspects of NOS involved, with there being a significant evolution in some cases (e.g., conception of scientific theory) and moderate in others (e.g., differences in scientific interpretations of the same phenomenon). This reveals that the activity has an educational utility for the education of PSSTs in NOS issues. The article concludes with an indication of some educational implications of the experience.

    The modern world can be described as a globalized risk society. It is characterized by increasing complexity, unpredictable consequences of techno-scientific innovations and production, and its environmental consequences. Therefore, chemistry, just like many other knowledge areas, is in an ongoing process of environmentalization. For example, green chemistry has emerged as a new chemical metadiscipline and movement. The philosophy of green chemistry was originally based on a suggestion of twelve principles for environment-friendly chemistry research and production. The present article problematizes limitations in green chemistry when it comes to education. It argues that the philosophy of green chemistry in the context of education needs to be extended with socio-critical perspectives to form educated professionals and citizens who are able to understand the complexity of the world, to make value-based decisions, and to become able to engage more thoroughly in democratic decision-making on sustainability issues. Different versions of sustainability-oriented science/chemistry education are discussed to sharpen a focus on the most complex type, which is Bildung-oriented, focusing emancipation and leading to eco-reflexive education. The term eco- reflexive is used for a problematizing stance towards the modern risk society, an understanding of the complexity of life and society and their interactions, and a responsibility for individual and collective actions towards socio-ecojustice and global sustainability. The philosophical foundation and characteristics of eco-reflexive science education are sketched on in the article.

  19. Autistic expertise: a critical reflection on the production of knowledge in autism studies.

    PubMed

    Milton, Damian Em

    2014-10-01

    The field of autism studies is a highly disputed territory within which competing contradictory discourses abound. In this field, it is the voices and claims of autistic people regarding their own expertise in knowledge production concerning autism that is most recent in the debate, and traditionally the least attended to. In this article, I utilise the theories of Harry Collins and colleagues in order to reflect upon and conceptualise the various claims to knowledge production and expertise within the field of autism studies, from the perspective of an author who has been diagnosed as being on the autism spectrum. The notion that autistic people lack sociality is problematised, with the suggestion that autistic people are not well described by notions such as the 'social brain', or as possessing 'zero degrees of cognitive empathy'. I then argue, however, that there is a qualitative difference in autistic sociality, and question to what extent such differences are of a biological or cultural nature, and to what extent interactional expertise can be gained by both parties in interactions between autistic and non-autistic people. In conclusion, I argue that autistic people have often become distrustful of researchers and their aims, and are frequently frozen out of the processes of knowledge production. Such a context results in a negative feedback spiral with further damage to the growth of interactional expertise between researchers and autistic people, and a breakdown in trust and communication leading to an increase in tension between stakeholder groups. The involvement of autistic scholars in research and improvements in participatory methods can thus be seen as a requirement, if social research in the field of autism is to claim ethical and epistemological integrity.

    Numerous scholars are now directing their attention to the education and learning implications of participatory resource and environmental governance because of the potential implications of these for generating the social mobilization necessary to achieve sustainability trajectories. Our work, and that of other researchers, establishes that public participation in environmental assessment (EA) provides fertile ground for considering the intricacies of governance as they relate to participation, and for examining the education and learning implications of participation. Since EA law requires in many cases that public voices be part of the decision process, it has resulted in the creation of fascinating, state-sanctioned, deliberative spaces for civic interactions. Our purpose here is to share, and build upon, a framework that conceptualizes the relationships among participation, education, learning and sustainability in an EA context. We do so by considering findings from studies we have undertaken on participation in EA in Canada since the early 90's. Our approach was interactive and collaborative. We each considered in detail the key results of our earlier work as they relate to education, learning and EA process design. The findings illuminate aspects of the conceptual framework for which there is considerable empirical evidence, such as the link between meaningful participation and critical education and the diversity of individual learning outcomes associated with public participation in EA. The findings also highlight those parts of the framework for which the empirical evidence is relatively sparse, such as the range of possible social learning outcomes, their congruence with sustainability criteria, and the roles of monitoring and cumulative and strategic assessments in shaping EA into an adaptive, learning system.

    Ventilator-associated pneumonia (VAP) is a common cause of morbidity in critically ill patients. Appropriate enteral feeding is the most important factor associated with the prevention of VAP. However, the standardization of enteral feeding methods needs clarification. The purpose of this systematic review was to synthesize the factors associated with enteral feeding in order to prevent VAP and to describe the characteristics of these factors. A comprehensive search was undertaken involving all major databases from their inception to September 2008 using medical subject heading terms associated with enteral feeding in relation to VAP. The overall reference list of identified studies was audited, and eligible studies included randomized controlled trials, controlled before-and-after (pre-post) studies and meta-analyses. To generate the characteristics of the factors associated with VAP, the reported components of these trials were pinpointed and categorized. A total of 14 papers were found that had investigated the factors linking enteral feeding and VAP. For these, 11 were randomized controlled trials, 1 was a meta-analysis and 2 were case-controlled analyses. Twelve of these 14 studies were conducted at a single institute and 2 were conducted at multiple institutes. The sample sizes varied from 10 to 2,528 subjects. Three major issues were identified based on the purpose of study interventions, and these were the effects of feeding method (continuous vs. intermittent), feeding site on aspiration (gastric vs. small bowel), and the timing of enteral feeding (early vs. late). The evidence suggests that a correct choice of enteral feeding method can effectively reduce complications due to aspiration. Furthermore, intermittent enteral feeding and with a small residual volume feed can reduce gastroesophageal reflux, and increased total intake volume and early feeding can reduce ICU mortality. Nonetheless, the effects of these choices on preventing VAP still need further

    The Urbanization and Global Environmental Change (UGEC) Project was established in 2005 when attention to the bidirectional interactions of urbanization and GEC issues and the associated system responses was very new and the community of UGEC researchers very small. Much of the urban scholarship used specific disciplinary lenses through which to understand the city, e.g., in terms of demographics and population growth, ecology of cities or economics of cities. Over the last decade new analytical lenses have revealed much more about how cities function, the underlying socio-economic and ecological processes that drive urbanization, their dynamic and teleconnected nature, and other bio-physical interactions within the Earth system. Furthermore, it is within the cities that the impacts of current and projected urbanization and environmental changes are felt, but also where action is taken and where great potential for intervention of urbanization trajectories exists towards creating more livable urban futures. A former IHDP core project, now Future Earth project, UGEC is in its sunset/synthesis phase and exploring future directions. This presentation will: Give an brief overview of UGEC evolution over the course of the last decade not only in terms of the science, but also the institution Present preliminary results from a critical analysis of UGEC's ten year role as a GEC research coordination project including its impact, strengths and weaknesses Make the case for greater interdisciplinarity (particularly across the physical sciences and humanities) and involvement of other stakeholders (private sector and decisionmakers) in future urbanization and environmental research, as 'urban' is a crosscutting issue that has both global to local scale implications Present work that UGEC is leading, which is to advance an urban agenda within the new Future Earth initiative as part of the recently awarded Cluster Activity 'Livable Urban Futures', as an example of research

    Chatzinikolaou, I; Raad, I I

    2000-12-01

    In modem medicine, central venous catheters (CVCs) have a pivotal role in the management of critically ill patients. The most serious complication of effective CVC placement is catheter-related bloodstream infection (CRBSI). Microbial colonization and CRBSI are the byproducts of the interaction of 4 factors: (1) microbial factors (hydrophobicity and exopolysaccharide production), (2) host factors (such protein adhesins as fibrin and fibronectin that attach to the catheter surface), (3) catheter material (hydrophobicity, surface charges, thrombogenicity), and (4) iatrogenic factors (total parenteral nutrition, interleukin-2). The organisms most frequently associated with CRBSI are Staphylococcus epidermidis, Staphylococcus aureus, and Candida spp. CRBSIs were traditionally diagnosed through semiquantitative or quantitative cultures of the catheter tip. However, the diagnosis can be achieved without catheter removal through cultures of blood specimens collected simultaneously though the CVC and a peripheral vein. Currently, the most effective method of preventing a CRBSI is the use of a CVC coated with antimicrobial agents. Intravenous administration of vancomycin for 7 days is adequate for an uncomplicated CRBSI caused by coagulase-negative staphylococci, and at least 10 days of therapy with beta-lactams is required for an uncomplicated infection caused by methicillin-sensitive S. aureus. CRBSI caused by Candida albicans or Candida parapsilosis can be treated with at least 14 days of therapy with fluconazole or amphotericin B. In the case of Candida krusei, only amphotericin B is effective.

    In this article, I provide some reflections on critical digital health research in the context of Health's 20th anniversary. I begin by outlining the various iterations of digital technologies that have occurred since the early 1990s--from Web 1.0 to Web 2.0 to Web 3.0. I then review the research that has been published on the topic of digital health in this journal over the past two decades and make some suggestions for the types of directions and theoretical perspectives that further sociocultural and political research could tackle. My concluding comments identify four main areas for further research: (1) devices and software, (2) data materialisations, (3) data practices and (4) data mobilities.

    The prevalence of smoking has increased among young people aged 14 to 18 between 1993 and 1999, and most notably among girls within the same period. These observations illustrate the necessity for significant changes in mass media campaigns and education programmes related to the prevention of smoking among youth. The objective of this survey, initiated by the city of Besançon and the French National Mutual Insurance of Doubs, was to describe and analyse the knowledge and rationale of high school students on tobacco and their opinions in terms of prevention. Twelve public and private high schools in Besançon and Morteau (Doubs-France) participated in the survey; the group also represented a mix of general and professional schools. The questionnaire was filled out by 970 students selected at random. 96% of the students indicated cancer as being the main illness linked to tobacco and 94% stated that second-hand smoke constitutes a health risk. 61% admitted to seeking out the psychoactive effects of smoking. The students responses confirm that the types of messages relayed in a smoking prevention campaign which have an impact on them are: evoking fear of death (74%) and the use of humor (16%). One-third of high school students find that it is unacceptable to forbid smoking on school premises. The knowledge of the dangers related to smoking is not sufficient to keep young people from smoking and confirms that an educational approach based solely on knowledge and facts will not be sufficient to decrease their tobacco consumption. It is important to take into account the image that young people have of tobacco as a means to combat stress in future prevention strategies and campaigns.

    Assessment of early feeding skills of vulnerable infants is common practice in neonatal care centers. However, assessment is often merely an identification of feeding outcomes, rather than a description of the infant's capacities and methods of adapting to the feeding challenge. Descriptive assessment of the feeding process takes into account the dynamic nature of feeding and notes changes that occur as the infant matures and gains feeding experience. Assessment of the variability that occurs during the feeding as the challenge changes, due to fatigue or physiologic instability, are critical to understanding the infant's feeding skills. As individual components of the feeding are assessed, such as sucking, swallowing and breathing, a reflective process builds understanding of the patterns of coordination of system components in relation to one another. Taking the whole into account and considering the dynamics of the process is necessary if we are going to select appropriate interventions targeted to the individual infant's feeding skills. Using a very preterm infant case, this paper will illustrate assessment of early feeding skills and demonstrate how reflection on and integration of the components of the assessment identifies potential targets for co-regulated, cue-based feeding.

  12. "Can we talk?" Using critical self-reflection and dialogue to build diversity and change organizational culture in nursing schools.

    PubMed

    Terhune, Carol Parker

    2006-01-01

    Nursing is often cited as a homogenous profession composed of a predominance of white females. It is sometimes posited that this homogeneity might be a contributor to the disparity of nursing care available to minority populations (Blakeney, 2002; Leininger, 1991). Today's nursing students do not mirror the nation's population as only 12.3% of RNs represent racial or ethnic minority groups (AACN, 2001). The absence of sufficiently diverse students in nursing schools, may have led to a dearth of qualified providers in underrepresented neighborhoods. Building diversity in nursing schools prepared specifically to reduce health disparities is, and will continue to be a challenge. While, some schools are beginning to yield successful returns, many are still searching for answers. The answer is not as simple as "increasing the numbers" or sending people to training seminars or conferences. This article focuses on what the author believes to be a preliminary and critical step to begin an effective and successful diversity initiative--critical self-reflection and dialogue. This involves the examination and deconstruction of old paradigms, assumptions, and prejudices, individually and collectively held and the construction of space, respect, and humility to discuss self in relation to "other."

  13. [[The prevention of food wastage by restoring the value to food: reflections of an agroeconomist].

    PubMed

    Segré, Andrea

    2014-01-01

    Each year, about one trillion USD worth of food sales is lost or wasted. In addition to its economic impacts, food wastage has significant societal costs that are born indirectly by taxpayers. Should damage costs associated with food wastage be accounted for, this global wastage appears much higher. In fact, the monetization of environmental costs such as the impact of greenhouse gases, land erosion, water use and pollinators loss amnounts to another trillion USD. Furthermore, a valuation of social costs, such as health effects of pesticides, loss of livelihoods and conflicts over natural resources adds another trillion USD. Noteworthy is the fact that not all food wastage reduction strategies are equal in terms of environmental efficiency and reducing food wastage must be a priority over energy recovery fromn food wastage. As a case study, the Italian National Plan for Food Waste Prevention (PINPAS) aims at reducing food wastage upstream the food chain, will be considered. PINPAS also seeks to improve recovery measures of unsold food. As indicated in the Guidelines on the preparation of food waste prevention programmes by the European Commission, PINPAS engages all stakeholders of the agri-food chain, from policy makers to civil groups aid producers. The first action will be the reintroduction of food education at school.

  14. Role of Transitional Care Measures in the Prevention of Readmission After Critical Illness.

    PubMed

    Peters, Jessica S

    2017-02-01

    Transitioning from the critical care unit to the medical-surgical care area is vital to patients' recovery and resolution of critical illness. Such transitions are necessary to optimize use of available hospital resources to meet patient care needs. One in 10 patients discharged from the intensive care unit are readmitted to the unit during their hospitalization. Critical care readmission is associated with significant increases in illness acuity, overall length of stay, and health care costs as well as a potential 4-fold increased risk of mortality. Patients with complex illness, multiple comorbid conditions, and a prolonged initial stay in the critical care unit are at an increased risk of being readmitted to the critical care unit and experiencing poor outcomes. Implementing nurse-driven measures that support continuity of care and consistent communication practices such as critical care outreach services, transitional communication tools, discharge planning, and transitional care units improves transitions of patients from the critical care environment and reduces readmission rates.

    2009-01-01

    The aim of the present article is to offer a tool to enlighten the comprehension of aggressive behavior and violent situations often found in educational institutions. The words 'violence' and 'aggressiveness' are not used in an unequivocal way, and the establishment of a map showing this fact allows designating places and ways of treatment specific for the phenomena. Following the theoretical model of the psychoanalyst Donald Winnicott, we will discuss the differences between aggressiveness and violence, illustrating them through the presentation of a case experienced by our health team in a public school in the state of Rio de Janeiro. In face of the difficulties found and the questions raised, we sought to show that the denaturalization of violence and the depathologization of aggressiveness offer us the possibility to propose actions which are not restricted to the control and correction of such manifestations, but can be more efficient in preventing the irruption and reproduction of violent situations for considering the social context in which they emerge and the subjective experiences involved.

  16. Use of Methadone for Prevention of Opioid Withdrawal in Critically Ill Children

    Jeffries, Sonia A; McGloin, Rumi; Pitfield, Alexander F; Carr, Roxane R

    2012-01-01

    Background Opioids are commonly administered to critically ill children for analgesia and sedation, but many patients experience opioid withdrawal upon discontinuation. The authors’ institution developed a protocol for using methadone to prevent opioid withdrawal in children who have received morphine by continuous IV infusion for 5 days or longer in the pediatric intensive care unit (PICU). Objectives The primary objectives were to determine if opioids were tapered according to the protocol and to determine the conversion ratio for IV morphine to oral methadone that was used. Secondary objectives were to describe the methadone dosage used and the clinical outcomes, to evaluate adjustments to methadone dosing, and to report the incidence of adverse effects. Methods A retrospective analysis of charts was conducted for pediatric patients who had received morphine by continuous IV infusion for 5 days or longer followed by methadone in the PICU between May 2008 and August 2009. Validated scoring systems (the Withdrawal Assessment Tool and the State Behavioral Scale) were used to assess symptoms of withdrawal and degree of sedation, respectively. Results Forty-three patients were included in the study, with median age of 8 months (range 0.25–201 months). For 31 patients (72%), the protocol was not used, and there were no patients for whom the protocol was followed to completion. The median duration of weaning was 10 days (range 0–91 days). The conversion ratio for IV morphine to oral methadone was 1:0.78 for anticipated 5-day weaning and 1:0.98 for anticipated 10-day weaning. During the first 10 days of weaning, 18 patients (42%) experienced withdrawal symptoms. The methadone dose was increased for 11 (26%) of the 43 patients. Patients were sedated for a median of 1 day (range 0–9 days), were comfortable for a median of 6.5 days (range 1–64 days), and were agitated for a median of 2.5 days (range 0–23 days). Naloxone was required for 2 patients. Conclusions

  17. Critical research gaps and translational priorities for the successful prevention and treatment of breast cancer

    2013-01-01

    Introduction Breast cancer remains a significant scientific, clinical and societal challenge. This gap analysis has reviewed and critically assessed enduring issues and new challenges emerging from recent research, and proposes strategies for translating solutions into practice. Methods More than 100 internationally recognised specialist breast cancer scientists, clinicians and healthcare professionals collaborated to address nine thematic areas: genetics, epigenetics and epidemiology; molecular pathology and cell biology; hormonal influences and endocrine therapy; imaging, detection and screening; current/novel therapies and biomarkers; drug resistance; metastasis, angiogenesis, circulating tumour cells, cancer ‘stem’ cells; risk and prevention; living with and managing breast cancer and its treatment. The groups developed summary papers through an iterative process which, following further appraisal from experts and patients, were melded into this summary account. Results The 10 major gaps identified were: (1) understanding the functions and contextual interactions of genetic and epigenetic changes in normal breast development and during malignant transformation; (2) how to implement sustainable lifestyle changes (diet, exercise and weight) and chemopreventive strategies; (3) the need for tailored screening approaches including clinically actionable tests; (4) enhancing knowledge of molecular drivers behind breast cancer subtypes, progression and metastasis; (5) understanding the molecular mechanisms of tumour heterogeneity, dormancy, de novo or acquired resistance and how to target key nodes in these dynamic processes; (6) developing validated markers for chemosensitivity and radiosensitivity; (7) understanding the optimal duration, sequencing and rational combinations of treatment for improved personalised therapy; (8) validating multimodality imaging biomarkers for minimally invasive diagnosis and monitoring of responses in primary and metastatic disease

    Over the past half century, coronary care units have expanded from specialized ischemia arrhythmia monitoring units into intensive care units (ICUs) for acutely ill and medically complex patients with a primary cardiac diagnosis. Patients admitted to contemporary coronary intensive care units (CICUs) are at risk for common and preventable critical care complications, yet many CICUs have not adopted standard-of-care prevention protocols and practices from general ICUs. In this article, we (1) review evidence-based interventions and care bundles that reduce the incidence of ventilator-associated pneumonia, excess sedation during mechanical ventilation, central line infections, stress ulcers, malnutrition, delirium, and medication errors and (2) recommend pragmatic adaptations for common conditions in critically ill patients with cardiac disease, and (3) provide example order sets and practical CICU protocol implementation strategies.

    Foth, Thomas; O'Byrne, Patrick; Holmes, Dave

    2016-06-01

    On 18 November 2014, the United Nations launched an urgent new campaign to end AIDS as a global health threat by 2030. With its proposed strategy, the UN follows leading scientists who had declared the failure of former prevention strategies and now were promoting a 'Seek and Treat for Optimal Prevention' (STOP) approach as the most cost-effective response to the pandemic to meet the goal of 'an AIDS-free generation'. STOP combines antiretroviral therapy and routine HIV screening to find persons unaware that they are HIV-positive, because research has shown that people consistently change their behaviour (i.e. increase condom use, have fewer partners) after an HIV diagnosis. AIDS activists have broadly criticized this strategy on different levels. In this article, we go beyond these criticisms and try to analyse the political rationalities behind this 'new' strategy. We believe that it is necessary to put the rationale underpinning the STOP programme into the context of broader societal transformations that can best be captured as the development of advanced liberal societies and the new emphasis on self-controlling or self-responsibility rather than on disciplining behaviour.

    2016-11-01

    There is a growing interest in English-speaking jurisdictions, including Australia, North America, Canada, the United Kingdom and New Zealand, about the prevention of sexual abuse perpetrated by children against other children. The aim of this review was to identify opportunities for research, policy and practice which could enhance the prevention agenda relating to the perpetration of sexual abuse by children through conducting a Critical Interpretive Synthesis. Eleven electronic databases were searched in the period from 22 April to 23 May 2013 and included: SocINDEX, Social Services Abstracts, Applied Social Sciences Index and Abstracts, Family and Society Studies Worldwide, Project Muse, PsychINFO, Family and Society Plus, Jstor, Expanded Academic ASAP, Web of Science and Google Scholar. Key individual journals were also searched, including Child Abuse and Neglect and the Journal of Interpersonal Violence, as well as the grey literature. The search was guided by the research question: How could the prevention agenda relating to sexual abuse perpetrated by children be enhanced? The systematic literature search yielded 3323 titles, and 34 of these papers were included in the final synthesis. The authors identified five domains operating in the evidence base: characteristics, causes, communications, interventions and treatments. A synthesising construct emerged from the review: prevention-enhancing interactions. This construct referred to the potential for enhancing the prevention agenda which exists as the evidence domains interact with one another, and with the public health model of prevention. The authors consider this review to be a timely contribution to the current agenda pertaining to sexual abuse perpetrated by children. It provides researchers, policy makers and practitioners in the field with an evidence-informed conceptualisation of opportunities for enhancing prevention work.

    In 2007, the World Health Organization published the Global Framework for Immunization Monitoring and Surveillance (GFIMS) outlining measures to enhance national surveillance for vaccine preventable diseases (VPDs). The GFIMS emphasized that VPD surveillance should be integrated and placed in a ‘unified framework’ building upon the strengths of existing surveillance systems to prevent duplication of activities common to all surveillance systems and to minimize human resource and supply expenditures. Unfortunately, there was little experience in actually developing integrated VPD surveillance. We describe the process of developing operational guidance for ministries of health to implement such an integrated surveillance system for multiple VPDs. PMID:23777699

    2009-03-01

    We applied the principles of Hazard Analysis and Critical Control Points (HACCP) to systematically analyse the care pathway of patients diagnosed with gonorrhoea to identify potential intervention opportunities for preventive action. Data were collected on individuals with culture-positive gonococcal infection during 27 February 2003 to 08 January 2004. Qualitative data were gathered within individual semi-structured interviews. Two hundred and twenty-three gonorrhoea patient episodes were evaluated. The median interval between presentation and treatment was significantly longer in females and men having sex with men (MSM), compared with heterosexual men (P = 0.002). Females were significantly more likely to be in regular relationships at the timepoint of perceived infection acquisition than heterosexuals or MSM (P < 0.0001). Four major themes emerged from the interviews: life-stage and infection risk, determinants of risk perception around sexual encounters, attitudes to preventing re-infection and condom use. These informed three potential 'critical control points': health-related attitudes/behaviours preceding infection; access to appropriate care and optimizing health promotion to prevent further infection.

    2008-09-01

    Previous studies have shown that youth are two to three times more likely than adults to report gambling related problems. This paper reports on the development and pilot evaluation of a school-based problem gambling prevention curriculum. The prevention program focused on problem gambling awareness and self-monitoring skills, coping skills, and knowledge of the nature of random events. The results of a controlled experiment evaluating the students learning from the program are reported. We found significant improvement in the students' knowledge of random events, knowledge of problem gambling awareness and self-monitoring, and knowledge of coping skills. The results suggest that knowledge based material on random events, problem gambling awareness and self-monitoring skills, and coping skills can be taught. Future development of the curriculum will focus on content to expand the students' coping skill options.

    2014-04-01

    Surgical site infection (SSI) is associated with prolonged hospital stay, increased morbidity, mortality and sanitary costs, and reduced patients quality of life. Many hospitals have adopted guidelines of scientifically-validated processes for prevention of surgical site and central-line catheter infections and sepsis. Most of these guidelines have resulted in an improvement in postoperative results. A review of the best available evidence on these measures in abdominal surgery is presented. The best measures are: avoidance of hair removal from the surgical field, skin decontamination with alcoholic antiseptic, correct use of antibiotic prophylaxis (administration within 30-60 min before incision, use of 1(st) or 2(nd) generation cephalosporins, single preoperative dosis, dosage adjustments based on body weight and renal function, intraoperative re-dosing if the duration of the procedure exceeds 2 half-lives of the drug or there is excessive blood loss), prevention of hypothermia, control of perioperative glucose levels, avoid blood transfusion and restrict intraoperative liquid infusion.

    1994-12-31

    The serious gap that exists between modern corrosion science and the real world, where a heavy toll is continuously paid to corrosion, is a clear indication that the present knowledge of corrosion mechanisms is not always translated into sound practices. The dichotomy between prevention principles discovered in a laboratory environment and their application on an industrial scale can often be felt at specialized conferences where scientists and operational engineers seem to be speaking different languages. The application of artificial intelligence to perform expert functions has opened new communication channels between various strata of corrosion knowledge holders. This paper reviews the efforts recently made public on the applications of the expert system technology to corrosion prevention and control.

    The prevalence of obesity among children has roughly tripled in the past 30 years. Given the numerous health risks associated with obesity, elementary schools have implemented a variety of prevention programs targeting this problem. This review examines recent studies of combinations of obesity prevention programs in US elementary schools and offers recommendations about effective strategies. We found 12 studies that met selection criteria and reviewed their findings related to obesity-related outcomes. Among the single intervention strategies, neither physical activity nor education alone demonstrated efficacy in reducing objective measures of obesity. Most studies of programs with two or three components (i.e., physical activity plus nutrition, physical activity plus both education and nutrition) reported statistically significant improvements in objective obesity-related outcomes. Studies evaluating programs with community and parental involvement suggest that these components may increase effectiveness. However, studies assessing outcomes following the cessation of the program showed a reversal of positive effects, suggesting that long-term implementation of programs is important for sustained gains. Results suggest that combinations of obesity prevention programs sustained over time are most likely to be effective.

    2012-06-01

    Elite athletes, particularly those engaged in endurance sports and those exposed chronically to airborne pollutants/irritants or allergens, are at increased risk for upper and lower airway dysfunction. Airway epithelial injury may be caused by dehydration and physical stress applied to the airways during severe exercise hyperpnoea and/or by inhalation of noxious agents. This is thought to initiate an inflammatory cascade/repair process that, ultimately, could lead to airway hyperresponsiveness (AHR) and asthma in susceptible athletes. The authors review the evidence relating to prevention or reduction of the risk of AHR/asthma development. Appropriate measures should be implemented when athletes exercise strenuously in an attempt to attenuate the dehydration stress and reduce the exposure to noxious airborne agents. Environmental interventions are the most important. Non-pharmacological strategies can assist, but currently, pharmacological measures have not been demonstrated to be effective. Whether early prevention of airway injury in elite athletes can prevent or reduce progression to AHR/asthma remains to be established.

    The manufacturer-recommended shift check for Zoll M Series defibrillators cannot detect some critical failures that could inhibit defibrillation or pacing. To improve detection of these failures and to limit their impact on patient care, hospitals should perform not only the routine perform not only the routine shift check, but also the twice-annual preventive maintenance procedure recommended by Zoll. Additionally, units exhibiting an error code--even one that appears to resolve itself--should be immediately removed from service and evaluated by the clinical engineering department.

  5. Supplemental Parenteral Nutrition Is the Key to Prevent Energy Deficits in Critically Ill Patients.

    PubMed

    Oshima, Taku; Heidegger, Claudia-Paula; Pichard, Claude

    2016-08-01

    This review emphasizes the role of a timely supplemental parenteral nutrition (PN) for critically ill patients. It contradicts the recommendations of current guidelines to avoid the use of PN, as it is associated with risk. Critical illness results in severe metabolic stress. During the early phase, inflammatory cytokines and mediators induce catabolism to meet the increased body energy demands by endogenous sources. This response is not suppressed by exogenous energy administration, and the early use of PN to reach the energy target leads to overfeeding. On the other hand, early and progressive enteral nutrition (EN) is less likely to cause overfeeding because of variable gastrointestinal tolerance, a factor frequently associated with significant energy deficit. Recent studies demonstrate that adequate feeding is beneficial during and after the intensive care unit (ICU) stay. Supplemental PN allows for timely adequate feeding, if sufficient precautions are taken to avoid overfeeding. Indirect calorimetry can precisely define the adequate energy prescription. Our pragmatic approach is to start early EN to progressively test the gut tolerance and add supplemental PN on day 3 or 4 after ICU admission, only if EN does not meet the measured energy target. We believe that supplemental PN plays a pivotal role in the achievement of adequate feeding in critically ill patients with intolerance to EN and does not cause harm if overfeeding is avoided by careful prescription, ideally based on energy expenditure measured by indirect calorimetry.

  7. Extrapolated experimental critical parameters of unreflected and steel-reflected massive enriched uranium metal spherical and hemispherical assemblies

    SciTech Connect

    Rothe, R.E.

    1997-12-01

    Sixty-nine critical configurations of up to 186 kg of uranium are reported from very early experiments (1960s) performed at the Rocky Flats Critical Mass Laboratory near Denver, Colorado. Enriched (93%) uranium metal spherical and hemispherical configurations were studied. All were thick-walled shells except for two solid hemispheres. Experiments were essentially unreflected; or they included central and/or external regions of mild steel. No liquids were involved. Critical parameters are derived from extrapolations beyond subcritical data. Extrapolations, rather than more precise interpolations between slightly supercritical and slightly subcritical configurations, were necessary because experiments involved manually assembled configurations. Many extrapolations were quite long; but the general lack of curvature in the subcritical region lends credibility to their validity. In addition to delayed critical parameters, a procedure is offered which might permit the determination of prompt critical parameters as well for the same cases. This conjectured procedure is not based on any strong physical arguments.

    The present review is based mainly on papers published between 2000 and 2011 and gives information about the properties of the carotenoid lycopene in chemical and biological systems and its possible role in preventing cardiovascular diseases (CVD). The main aim of this report is to highlight its role as an antioxidant, also reported are bioactive properties that may influence the development of foam cells and protection against endothelial cell damage. The paper will also examine recent observations that lycopene may improve blood flow and reduce inflammatory responses. Lycopene possesses antioxidant properties in vitro, and some epidemiological studies have reported protective effects against the progression of CVD. The oxidation of human low density lipoproteins (LDL) is a fundamental mechanism in the initiation of atherosclerosis. A beneficial role of lycopene as antioxidant in the prevention of CVD is suggested but the data are still controversial. Lycopene is believed to be the most potent carotenoid antioxidant in vitro. Tissue culture experiments and animal studies support potential cardioprotective effects for lycopene and other carotenoids in the blood. Most studies showed beneficial effects of lycopene to individuals who are antioxidant-deficient like elderly patients, or humans exposed to higher levels of oxidative stress like smokers, diabetics, hemodialysis patients and acute myocardial infarction patients. By defining the right population and combining antioxidant potentials of lycopene with vitamins and other bioactive plant compounds, the beneficial role of lycopene in CVD can be clarified in future studies.

    Trachoma is an ocular disease caused by repeated infection with Chlamydia trachomatis. It is the leading cause of infectious blindness globally, responsible for 5.9 million cases of blindness. Although trachomatous blindness is untreatable, it is eminently possible to prevent and the World Health Organization promotes the use of the SAFE strategy (surgery to treat end-stage disease, antibiotics to reduce the reservoir of infection, facial cleanliness, and environmental improvement to reduce transmission of C trachomatis) for this purpose. In this review we have assessed the evidence base supporting the elements of the SAFE strategy. We find strong support for the efficacy of the surgery and antibiotics components, although the optimal antibiotic regimens have not yet been established. The evidence for an effect of health education and environmental improvement is weaker, and depends mostly on cross-sectional observational studies.

    This paper aims to assess the role of individual types and cumulative life adversity for understanding depressive symptomatology and aggressive behavior. Data were collected in 2011 as part of the Teen Life Online and in Schools Study from 916 ethnically-diverse students from 12 middle, K-8, 6-12 and high schools in the Midwest United States. Youth reported an average of 4.1 non-victimization adversities and chronic stressors in their lifetimes. There was a linear relationship between number of adversities and depression and aggression scores. Youth reporting the highest number of adversities (7 or more) had significantly higher depression and aggression scores than youth reporting any other number of adversities suggesting exposure at this level is a critical tipping point for mental health concerns. Findings underscore an urgent need to support youth as they attempt to negotiate, manage, and cope with adversity in their social worlds.

    Despite continuous efforts to retrieve aerosol optical depth (AOD) using a conventional 5-channelmeteorological imager in geostationary orbit, the accuracy in urban areas has been poorer than other areas primarily due to complex urban surface properties and mixed aerosol types from different emission sources. The two largest error sources in aerosol retrieval have been aerosol type selection and surface reflectance. In selecting the aerosol type from a single visible channel, the season-dependent aerosol optical properties were adopted from longterm measurements of Aerosol Robotic Network (AERONET) sun-photometers. With the aerosol optical properties obtained fromthe AERONET inversion data, look-up tableswere calculated by using a radiative transfer code: the Second Simulation of the Satellite Signal in the Solar Spectrum (6S). Surface reflectance was estimated using the clear sky composite method, awidely used technique for geostationary retrievals. Over East Asia, the AOD retrieved from the Meteorological Imager showed good agreement, although the values were affected by cloud contamination errors. However, the conventional retrieval of the AOD over Hong Kong was largely underestimated due to the lack of information on the aerosol type and surface properties. To detect spatial and temporal variation of aerosol type over the area, the critical reflectance method, a technique to retrieve single scattering albedo (SSA), was applied. Additionally, the background aerosol effect was corrected to improve the accuracy of the surface reflectance over Hong Kong. The AOD retrieved froma modified algorithmwas compared to the collocated data measured by AERONET in Hong Kong. The comparison showed that the new aerosol type selection using the critical reflectance and the corrected surface reflectance significantly improved the accuracy of AODs in Hong Kong areas,with a correlation coefficient increase from0.65 to 0.76 and a regression line change from tMI [basic algorithm] = 0

    An unacceptably large percent of women experience sexual assault during their collegiate years and efforts to eliminate sexual assault exist in various forms at numerous universities. The only way to effectively decrease the occurrence of rape on college campuses is to stop the perpetrators. This review examined established sexual assault prevention programs designed for college men to determine if an ideal educational program exists, or if one can be established, to effectively change male attitudes and behaviors about sexual assault. A library search of scientific databases yielded seven studies, published from 2000 to 2007, that met inclusion criteria. Through a variety of interventions, a measurable number of formerly held attitudes about rape myth and the role of the bystanders in an assaultive situation were effectively changed immediately postintervention in several studies. In addition, one study demonstrated sustained behavioral change. These results can effectively be used to provide education for forensic and school-based nurses to guide practice for development of educational programs to successfully change harmful attitudes and beliefs that contribute to rape.

    Prevention of skipping of exon 7 during pre-mRNA splicing of Survival Motor Neuron 2 (SMN2) holds the promise for cure of spinal muscular atrophy (SMA), a leading genetic cause of infant mortality. Here, we report T-cell-restricted intracellular antigen 1 (TIA1) and TIA1-related (TIAR) proteins as intron-associated positive regulators of SMN2 exon 7 splicing. We show that TIA1/TIAR stimulate exon recognition in an entirely novel context in which intronic U-rich motifs are separated from the 5' splice site by overlapping inhibitory elements. TIA1 and TIAR are modular proteins with three N-terminal RNA recognition motifs (RRMs) and a C-terminal glutamine-rich (Q-rich) domain. Our results reveal that any one RRM in combination with a Q domain is necessary and sufficient for TIA1-associated regulation of SMN2 exon 7 splicing in vivo. We also show that increased expression of TIA1 counteracts the inhibitory effect of polypyrimidine tract binding protein, a ubiquitously expressed factor recently implicated in regulation of SMN exon 7 splicing. Our findings expand the scope of TIA1/TIAR in genome-wide regulation of alternative splicing under normal and pathological conditions.

  17. Antiplatelet therapy for secondary prevention of noncardioembolic ischemic stroke: a critical review.

    2008-05-01

    For patients with ischemic stroke or transient ischemic attack caused by atherothromboembolism, immediate and long-term aspirin reduces the relative risk of recurrent stroke, MI, and death attributable to vascular causes. Oral anticoagulation is not more effective than aspirin. Long-term clopidogrel reduces the relative risk of stroke, MI, or vascular death by about 9% (0.3% to 16.5%) compared with aspirin. Any long-term benefits of clopidogrel combined with aspirin, compared with aspirin or clopidogrel alone, appear to be offset by increased major bleeding. The combination of aspirin and extended-release dipyridamole reduces the relative odds of stroke, MI, or vascular death by about 18% (odds ratio 0.82, 0.74 to 0.91) compared with aspirin alone without causing more bleeding. Cilostazole reduces the risk of stroke, MI, or vascular death by 39% compared to placebo. A large clinical trial comparing clopidogrel with the combination of aspirin and dipyridamole, in >20 000 patients with recent (<120 days) atherothrombotic ischemic stroke, is expected to report in 2008. Emerging antiplatelet therapies presently being evaluated for secondary prevention of atherothromboembolism include other P(2)Y(12) ADP receptor antagonists (prasugrel, cangrelor, AZD 6140), thromboxane receptor antagonists (eg, S18886 - terutroban), and thrombin receptor (PAR-1) antagonists (eg, SCH530348).

  18. Apolipoprotein A-V gene therapy for disease prevention / treatment: a critical analysis.

    PubMed

    Forte, Trudy M; Sharma, Vineeta; Ryan, Robert O

    2016-03-01

    Apolipoprotein (apo) A-V is a novel member of the class of exchangeable apo's involved in triacylglycerol (TG) homeostasis. Whereas a portion of hepatic-derived apoA-V is secreted into plasma and functions to facilitate lipoprotein lipase-mediated TG hydrolysis, another portion is recovered intracellularly, in association with cytosolic lipid droplets. Loss of apoA-V function is positively correlated with elevated plasma TG and increased risk of cardiovascular disease. Single nucleotide polymorphisms (SNP) in the APOA5 locus can affect transcription efficiency or introduce deleterious amino acid substitutions. Likewise, rare mutations in APOA5 that compromise functionality are associated with increased plasma TG and premature myocardial infarction. Genetically engineered mouse models and human population studies suggest that, in certain instances, supplementation with wild type (WT) apoA-V may have therapeutic benefit. It is hypothesized that individuals that manifest elevated plasma TG owing to deleterious APOA5 SNPs or rare mutations would respond to WT apoA-V supplementation with improved plasma TG clearance. On the other hand, subjects with hypertriglyceridemia of independent origin (unrelated to apoA-V function) may not respond to apoA-V augmentation in this manner. Improvement in the ability to identify individuals predicted to benefit, advances in gene transfer technology and the strong connection between HTG and heart disease, point to apoA-V supplementation as a viable disease prevention / therapeutic strategy. Candidates would include individuals that manifest chronic TG elevation, have low plasma apoA-V due to an APOA5 mutation/polymorphism and not have deleterious mutations/polymorphisms in other genes known to influence plasma TG levels.

    Objective Nosocomial infection / sepsis occurs in up to 40% of children requiring long stay intensive care. Zinc, selenium, glutamine, metoclopramide (a prolactin secretalogue), and or whey protein supplementation have been effective in reducing infection and sepsis in other populations. We evaluated whether daily nutriceutical supplementation with zinc, selenium, glutamine, and metoclopramide, compared to whey protein would reduce the occurrence of nosocomial infection / sepsis in this at-risk population. Design Randomized double blinded comparative effectiveness trial. Setting Eight pediatric intensive care units in the NICHD Collaborative Pediatric Critical Care Research Network. Patients Two hundred and ninety three long stay intensive care patients (age 1–17 years) expected to require more than 72 hours of invasive care. Interventions Patients were stratified according to immunocompromised status and center and then randomly assigned to receive daily enteral zinc, selenium, glutamine and IV metoclopramide (n = 149 ZSGM), or daily enteral whey protein (n = 144 WHEY) and IV saline, for up to 28 days of intensive care unit stay. The primary endpoint was time to development of nosocomial sepsis / infection. The analysis was intention to treat. Measurements and Main Results There were no differences by assigned treatment in the overall population with respect to time until the first episode of nosocomial infection / sepsis (median WHEY 13.2 days vs ZSGM 12.1 days, p=0.29 by log rank test) or the rate of nosocomial infection / sepsis (4.83/100 days WHEY vs. 4.99/100 days ZSGM, p = 0.81). Only 9% of the 293 subjects were immunocompromised and there was a reduction in rate of nosocomial infection / sepsis with ZSGM in this immunocompromised group (6.09/100 days WHEY vs 1.57/100 days ZSGM, p value = 0.011). Conclusions Compared with WHEY supplementation, ZSGM conferred no advantage in the immunecompetent population. Further evaluation of ZSGM supplementation is

    Enfant terrible of psychiatry and widely known as one of its most indefatigable as well as iconoclastic critics, Thomas Szasz (1961–2012) had a prolific writing career that extended some 51 years beyond the publication of his first book, The Myth of Mental Illness, in 1961. This editorial identifies and critically discusses three major themes in Szasz's writings: his contention that there is no such thing as mental illness, his contention that individual responsibility is never compromised in those suffering from what is generally considered as mental illness, and his perennial interest in calling attention to the political nature of psychiatric diagnosis.

    Paraffinic oil has been exposed to UF{sub 6} gas in seal exhaust pumps and cascade equipment at the Portsmouth Gaseous Diffusion Plant. The resulting mixture is more nuclearly reactive than mixtures of UO{sub 2}F{sub 2} and H{sub 2}O and is not bounded by the subcritical mass limits presented in several nuclear criticality safety guides. The purpose of this analysis is to determine several critical parameters; specifically, (1) k{sub {infinity}} and the critical mass for several enrichments and moderation levels and (2) the mass limits for these mixtures. The estimated critical masses for the UF{sub 4}-oil systems are smaller than for the UO{sub 2}F{sub 2}-H{sub 2}O systems. The suggested mass limits for the UF{sub 4}-oil systems are 0.240, 0.280, 0.350, 0.430, and 0.670, and 1.170 kg {sup 235}U for enrichments of 100, 50, 20, 10, 5, and 3 wt.% {sup 235}U respectively.

Staff at the Oak Ridge National Laboratory (ORNL) in the US and the Centre de Valduc in France planned this experiment. The experiment was conducted on October 19, 2010 in the SILENE critical assembly facility at Valduc. Several other organizations contributed to this experiment and the subsequent evaluation, including CEA Saclay, Lawrence Livermore National Laboratory (LLNL), the Y-12 National Security Complex (NSC), Babcock International Group in the United Kingdom, and Los Alamos National Laboratory (LANL). The goal of this experiment was to measure neutron activation and thermoluminescent dosimeter (TLD) doses from a source similar to a fissile solution critical excursion. The resulting benchmark can be used for validation of computer codes and nuclear data libraries as required when performing analysis of criticality accident alarm systems (CAASs). A secondary goal of this experiment was to qualitatively test performance of two CAAS detectors similar to those currently and formerly in use in some US DOE facilities. The detectors tested were the CIDAS MkX and the Rocky Flats NCD-91. The CIDAS detects gammas with a Geiger-Muller tube and the Rocky Flats detects neutrons via charged particles produced in a thin 6LiF disc depositing energy in a Si solid state detector. These detectors were being evaluated to determine whether they would alarm, so they were not expected to generate benchmark quality data.

    Escalating costs, increasing multi-morbidity, medically unexplained health problems, complex risk, poly-pharmacy and antibiotic resistance can be regarded as artefacts of the traditional knowledge production in Western medicine, arising from its particular worldview. Our paper presents a historically grounded critical analysis of this view. The materialistic shift of Enlightenment philosophy, separating subjectivity from bodily matter, became normative for modern medicine and yielded astonishing results. The traditional dichotomies of mind/body and subjective/objective are, however, incompatible with modern biological theory. Medical knowledge ignores central tenets of human existence, notably the physiological impact of subjective experience, relationships, history and sociocultural contexts. Biomedicine will not succeed in resolving today's poorly understood health problems by doing 'more of the same'. We must acknowledge that health, sickness and bodily functioning are interwoven with human meaning-production, fundamentally personal and biographical. This implies that the biomedical framework, although having engendered 'success stories' like the era of antibiotics, needs to be radically revised.

  14. Overcoming phase 1 delays: the critical component of obstetric fistula prevention programs in resource-poor countries

    PubMed Central

    2012-01-01

    Background An obstetric fistula is a traumatic childbirth injury that occurs when labor is obstructed and delivery is delayed. Prolonged obstructed labor leads to the destruction of the tissues that normally separate the bladder from the vagina and creates a passageway (fistula) through which urine leaks continuously. Women with a fistula become social outcasts. Universal high-quality maternity care has eliminated the obstetric fistula in wealthy countries, but millions of women in resource-poor nations still experience prolonged labor and tens of thousands of new fistula sufferers are added to the millions of pre-existing cases each year. This article discusses fistula prevention in developing countries, focusing on the factors which delay treatment of prolonged labor. Discussion Obstetric fistulas can be prevented through contraception, avoiding obstructed labor, or improving outcomes for women who develop obstructed labor. Contraception is of little use to women who are already pregnant and there is no reliable screening test to predict obstruction in advance of labor. Improving the outcome of obstructed labor depends on prompt diagnosis and timely intervention (usually by cesarean section). Because obstetric fistulas are caused by tissue compression, the time interval from obstruction to delivery is critical. This time interval is often extended by delays in deciding to seek care, delays in arriving at a hospital, and delays in accessing treatment after arrival. Communities can reasonably demand that governments and healthcare institutions improve the second (transportation) and third (treatment) phases of delay. Initial delays in seeking hospital care are caused by failure to recognize that labor is prolonged, confusion concerning what should be done (often the result of competing therapeutic pathways), lack of women’s agency, unfamiliarity with and fear of hospitals and the treatments they offer (especially surgery), and economic constraints on access to

    Critical thinking is a process applied to midwifery theory, research and experience. It is a positive activity, responsive to context, drawing on negative and positive triggers and emotions to suggest ways of acting in future. Practice-based and reflective midwifery assignments should reflect the midwifery goals of critical thinking. This may require adjustments in assessment criteria and a questioning of standard academic conventions.

    E-cadherin is a central molecule in the process of gastric carcinogenesis and its posttranslational modifications by N-glycosylation have been described to induce a deleterious effect on cell adhesion associated with tumor cell invasion. However, the role that site-specific glycosylation of E-cadherin has in its defective function in gastric cancer cells needs to be determined. Using transgenic mice models and human clinical samples, we demonstrated that N-acetylglucosaminyltransferase V (GnT-V)-mediated glycosylation causes an abnormal pattern of E-cadherin expression in the gastric mucosa. In vitro models further indicated that, among the four potential N-glycosylation sites of E-cadherin, Asn-554 is the key site that is selectively modified with β1,6 GlcNAc-branched N-glycans catalyzed by GnT-V. This aberrant glycan modification on this specific asparagine site of E-cadherin was demonstrated to affect its critical functions in gastric cancer cells by affecting E-cadherin cellular localization, cis-dimer formation, molecular assembly and stability of the adherens junctions and cell–cell aggregation, which was further observed in human gastric carcinomas.

    Background Tuberculosis is a major cause of morbidity and mortality globally. Recent scholarly attention to public health ethics provides an opportunity to analyze several ethical issues raised by the global tuberculosis pandemic. Discussion Recently articulated frameworks for public health ethics emphasize the importance of effectiveness in the justification of public health action. This paper critically reviews the relationship between these frameworks and the published evidence of effectiveness of tuberculosis interventions, with a specific focus on the controversies engendered by the endorsement of programs of service delivery that emphasize direct observation of therapy. The role of global economic inequities in perpetuating the tuberculosis pandemic is also discussed. Summary Tuberculosis is a complex but well understood disease that raises important ethical challenges for emerging frameworks in public health ethics. The exact role of effectiveness as a criterion for judging the ethics of interventions needs greater discussion and analysis. Emerging frameworks are silent about the economic conditions contributing to the global burden of illness associated with tuberculosis and this requires remediation. PMID:15113419

  18. The life course model as a framework for post-conflict health analysis: reflections on the Gulf War critical period.

    2016-01-01

    In the Kuwait context, from January 1991 to December 1991, there were a series of chemical and psychological Gulf War-era exposures that left persistent, long-term damage. Extreme stress from a critical event speeds up the usual disease latency period, and may be part of a synergistic effect that leads to higher disease rates over a shorter period of time. I am interested in the impact of armed conflict on health outcomes over the life course in Kuwait, and particularly the pathways through which armed conflict causes changes in health on a population level. In this paper, I propose a culturally sensitive, post-conflict socio-ecological model that informs a three-pronged health study. I propose a macro-micro mix that includes an ecological study, a case-control study and a qualitative study to investigate Kuwait's post-conflict health concerns. Thus, I revise the concept of 'post-conflict health' as a trajectory that is mediated through different, complex social levels and develops over time during the latency period. The main advantage of a macro-micro mix approach for post-conflict health is that it contextualizes the Gulf War as an environmental health issue.

  19. Stress response to handling is short lived but may reflect personalities in a wild, Critically Endangered tortoise species

    Abstract We investigated the acute stress response associated with animal personalities by measuring plasma glucocorticoids throughout handling and collected ~2 years of movement and behavioural data in a wild, Critically Endangered animal, Astrochelys radiata (radiated tortoise). To determine whether our standard, brief conscientious handling procedures induce a stress response in our target species, we applied a stressor by way of initial animal processing and deployment of telemetry equipment. During surveys and processing, we sampled animals immediately upon detection, again after completing transmitter attachment and processing, and a final time the following day. We then used radiotelemetry to follow a subset of the animals for 22 months while collecting behavioural, climatic and location data. We found that brief and conscientious handling did not illicit consistent changes in plasma concentrations of the stress hormone corticosterone (CORT) but did reveal tremendous individual variation in response. The CORT concentration ranged more than 200-fold after imposing the stressor and returned to near-baseline values by the following day. When we accounted for the wide variation by calculating the degree of each individual's stress response relative to its baseline over its processing time, we discovered two non-overlapping physiological response types; those in which CORT concentrations increased dramatically in response to handling (219 ± 89.8 pg/ml/min) and those in which CORT varied only slightly (5.3 ± 8.9 pg/ml/min). The response types (strong vs. mild) also predicted body condition, home range size, activity, and behavioural tendencies. The degree of the individual's stress response in this species may be one component of correlated physiological and behavioural traits (animal personalities), which have previously been obscured in other chelonian studies by the use of mean values and should be considered in future conservation management applications

    Lesion-deficit studies support the hypothesis that the left anterior temporal lobe (ATL) plays a critical role in retrieving names of concrete entities. They further suggest that different regions of the left ATL process different conceptual categories. Here we test the specificity of these relationships and whether the anatomical segregation is related to the underlying organization of white matter connections. We reanalyzed data from a previous lesion study of naming and recognition across five categories of concrete entities. In voxelwise logistic regressions of lesion-deficit associations, we formally incorporated measures of disconnection of long-range association fiber tracts (FTs) and covaried for recognition and non-category specific naming deficits. We also performed fiber tractwise analyses to assess whether damage to specific FTs was preferentially associated with category-selective naming deficits. Damage to the basolateral ATL was associated with naming deficits for both unique (famous faces) and non-unique entities, whereas the damage to the temporal pole was associated with naming deficits for unique entities only. This segregation pattern remained after accounting for comorbid recognition deficits or naming deficits in other categories. The tractwise analyses showed that damage to the uncinate fasciculus was associated with naming impairments for unique entities, while damage to the inferior longitudinal fasciculus was associated with naming impairments for non-unique entities. Covarying for FT transection in voxelwise analyses rendered the cortical association for unique entities more focal. These results are consistent with the partial segregation of brain system support for name retrieval of unique and non-unique entities at both the level of cortical components and underlying white matter fiber bundles. Our study reconciles theoretic accounts of the functional organization of the left ATL by revealing both category-related processing and

    Hip fractures are an acute and worsening public health problem. They mainly affect elderly people, a population group that is highly vulnerable to disease and accidents, and to falls in particular. Although it has been suggested that osteoporosis is the cause of hip fractures, they mainly occur after a fall has been suffered. The underlying causes of a fall are not related to osteoporosis, although pharmaceutical companies have coined the term “osteoporotic fracture” for hip fractures in the elderly. Drug treatments for osteoporosis have not diminished the frequency of these injuries, nor have they prevented the occurrence of a subsequent fracture. Since pharmaceutical interests require osteoporosis to be considered a disease, rather than a normal condition of senescence, they go further by assuming that treatment for osteoporosis is essential, and that this policy will diminish the incidence of hip fractures. On the other hand, the origin and treatment of conditions that may be conducive to provoking falls are very difficult to elucidate. In this paper, we consider some of the medical and social problems that arise in this area, as well as conflicts of interest regarding the aetiopathogenesis and prevention of hip fracture, and propose a new paradigm for the prevention of falls.

  5. Preventing Healthcare-Associated Infections by Monitoring the Cleanliness of Medical Devices and Other Critical Points in a Sterilization Service.

    It is well known that the common goal of all central sterile supply departments (CSSDs) is to prevent healthcare-associated infections. Such infections entail high costs to society, not only economic but also social. Therefore, delivering safe medical devices and guaranteeing a positive contribution to the control of healthcare-associated infections form the main responsibilities of a CSSD. The monitoring of the effectiveness of medical device cleaning processes is highly recommended. However, ensuring a flawless environment for the preparation, assembly, and packaging of medical devices and clean handling of sterilized items is crucial to achieving the goal of safe medical devices. This study analyzed not only the cleanliness of surgical instruments but also two critical aspects of the surrounding environment: the cleanliness of work surfaces and the cleanliness of workers' hands. To evaluate the cleanliness of surgical instruments, two methods were used: the adenosine triphosphate (ATP) detection method and a residual protein test. It was not the intention of this work to make an exhaustive comparison of these methods. The ATP bioluminescence method was also used for monitoring the cleanliness of work surfaces and workers' hands. The aims of this study were to establish the most suitable method of evaluating the cleanliness of reusable medical devices in the CSSD and to assess the quality of the environment. Assessing the surgical instruments, work surfaces, and staff hands for cleanliness allowed the identification of possible contamination sources and to correct them by improving cleaning/disinfection protocols. Furthermore, the use of ATP monitoring tests of workers' hands highlighted the importance of staff compliance with good practice guidelines. Thus, these results have a positive impact on the CSSD quality system and, consequently, on patient safety.

    The disparity in health status between Indigenous and non-Indigenous people in Australia and New Zealand is widely known, and efforts to address this through medical education are evidenced by initiatives such as the Committee of Deans of Australian Medical Schools' Indigenous Health Curriculum Framework. These efforts have focused primarily on formal curriculum reform. In this article, the authors discuss the role of the hidden curriculum in influencing the teaching and learning of Indigenous health (i.e., the health of Indigenous people) during medical training and suggest that in order to achieve significant changes in learning outcomes, there needs to be better alignment of the formal and hidden curriculum. They describe the Critical Reflection Tool as a potential resource through which educators might begin to identify the dimensions of their institution's hidden curricula. If used effectively, the process may guide institutions to better equip medical school graduates with the training necessary to advance changes in Indigenous health.

    The potential energy surfaces of even-even Sm146-156 are investigated in the constrained reflection-asymmetric relativistic mean-field approach with parameter set PK1. It is shown that the critical-point candidate nucleus Sm152 marks the shape/phase transition not only from U(5) to SU(3) symmetry, but also from the octupole-deformed ground state in Sm150 to the quadrupole-deformed ground state in Sm154. By including the octupole degree of freedom, an energy gap near the Fermi surface for single-particle levels in Sm152 with β2=0.14~0.26 is found and the important role of the octupole deformation driving pair ν2f7/2 and ν1i13/2 is demonstrated.

  8. Resisting the binarism of victim and agent: Critical reflections on 20 years of scholarship on young women and heterosexual practices in South African contexts.

    2016-01-01

    The last 20 years have seen a proliferation of research, spurred by the imperatives of the HIV epidemic and reportedly high rates of gender-based violence, on heterosexual practices in the South African context. Research has focused on how poverty, age and gender within specific cultural contexts shape sexual agency and provide a context for unequal, coercive and violent practices for young women. This paper takes stock of what we currently 'know' about heterosex and critically reflects on the political and ideological effects of such research, specifically in the light of young women's agency. A primary concern is that efforts to address gender inequality and the normative gender practices that shape inequitable heterosexual practices may have functioned to reproduce the very discourses that underpin such inequalities. The paper 'troubles' the victim-agency binarism as it has been played out in South African research on heterosex, raising concerns about how the research may reproduce gendered, classed and raced othering practices and discourses and bolstered regulatory and disciplinary responses to young women's sexualities. The paper argues for critical, feminist self-reflexivity that should extend to re-thinking methodologies entrenched in frameworks of authority and surveillance.

    As obesity rates increase, so too do the risks of type 2 diabetes, cardiovascular disease, and numerous other detrimental conditions. The prevalence of obesity in U.S. adults more than doubled between 1980 and 2010, from 15.0 to 36.1%. Although this trend may be leveling off, obesity and its individual, societal, and economic costs remain of grave concern. In June 2014, a Diabetes Care Editors’ Expert Forum convened to review the state of obesity research and discuss the latest prevention initiatives and behavioral, medical, and surgical therapies. This article, an outgrowth of the forum, offers an expansive view of the obesity epidemic, beginning with a discussion of its root causes. Recent insights into the genetic and physiological factors that influence body weight are reviewed, as are the pathophysiology of obesity-related metabolic dysfunction and the concept of metabolically healthy obesity. The authors address the crucial question of how much weight loss is necessary to yield meaningful benefits. They describe the challenges of behavioral modification and predictors of its success. The effects of diabetes pharmacotherapies on body weight are reviewed, including potential weight-neutral combination therapies. The authors also summarize the evidence for safety and efficacy of pharmacotherapeutic and surgical obesity treatments. The article concludes with an impassioned call for researchers, clinicians, governmental agencies, health policymakers, and health-related industries to collectively embrace the urgent mandate to improve prevention and treatment and for society at large to acknowledge and manage obesity as a serious disease.

    A series of critical experiments were completed in 1962-1965 at Oak Ridge National Laboratory’s Critical Experiments Facility in support of the Medium-Power Reactor Experiments (MPRE) program. In the late 1950’s efforts were made to study “power plants for the production of electrical power in space vehicles”. The MPRE program was a part of those efforts and studied the feasibility of a stainless steel system, boiling potassium 1 MW(t), or about 140 kW(e), reactor. The program was carried out in [fiscal years] 1964, 1965, and 1966. A summary of the program’s effort was compiled in 1967. The delayed critical experiments were a mockup of a small, potassium-cooled space power reactor for validation of reactor calculations and reactor physics methods. Initial experiments, performed in November and December of 1962, consisted of a core of 253 unmoderated stainless steel tubes, each containing 26 UO2 fuel pellets, surrounded by a graphite reflector. Measurements were made to determine critical reflector arrangements, fission-rate distributions, and cadmium ratio distributions. “The [assemblies were built] on [a] vertical assembly machine so that the movable part was the core and bottom reflector.” The first two experiments in the series were evaluated in HEU-COMP-FAST-001 (SCCA-FUND-EXP-001) and HEU-COMP-FAST-002 (SCCA-FUND-EXP-002). The first experiment had the 253 fuel tubes packed tightly into a 22.87 cm outside diameter (OD) core tank (References 1 and 2). The second experiment in the series, performed in early 1963, had the 253 fuel tubes at a 1.506-cm triangular lattice in a 25.96 cm OD core tank and graphite reflectors on all sides. The third set of experiments in the series, performed in mid-1963, which is studied in this evaluation, used beryllium reflectors. The beryllium reflected system was the preferred reactor configuration for this application because of the small thickness of the reflector. The two core configurations had the 253 fuel tubes

    Introduction Postintensive care syndrome (PICS) is defined as a new or worsening impairment in cognition, mental health and physical function after critical illness. There is little evidence regarding treatment of patients with PICS; new directions for effective treatment strategies are urgently needed. Early physiotherapy may prevent or reverse some physical impairments in patients with PICS, but no systematic reviews have investigated the effectiveness of early rehabilitation on PICS-related outcomes. The purpose of this systematic review is to evaluate whether early rehabilitative interventions in critically ill patients can prevent PICS and decrease mortality. Methods We will conduct a systematic review and meta-analysis of early rehabilitation for the prevention of PICS in critically ill adults. We will search PubMed, EMBASE and the Cochrane Central Register of Controlled Trials for published randomised controlled trials. We will screen search results and assess study selection, data extraction and risk of bias in duplicate, resolving disagreements by consensus. We will pool data from clinically homogeneous studies using a random-effects meta-analysis; assess heterogeneity of effects using the χ2 test of homogeneity; and quantify any observed heterogeneity using the I2 statistic. We will use the Grading of Recommendations Assessment, Development and Evaluation approach to rate the quality of evidence. Discussion This systematic review will present evidence on the prevention of PICS in critically ill patients with early rehabilitation. Ethics Ethics approval is not required. Dissemination The results will be disseminated via peer-reviewed journal publication, conference presentation(s) and publications for patient information. Trial registration number CRD42016039759.

  1. Impulsive delayed reward discounting as a genetically-influenced target for drug abuse prevention: a critical evaluation.

    2015-01-01

    This review evaluates the viability of delayed reward discounting (DRD), an index of how much an individual devalues a future reward based on its delay in time, for genetically-informed drug abuse prevention. A review of the literature suggests that impulsive DRD is robustly associated with drug addiction and meets most of the criteria for being an endophenotype, albeit with mixed findings for specific molecular genetic influences. Several modes of experimental manipulation have been demonstrated to reduce DRD acutely. These include behavioral strategies, such as mindfulness, reward bundling, and episodic future thinking; pharmacological interventions, including noradrenergic agonists, adrenergic agonists, and multiple monoamine agonists; and neuromodulatory interventions, such as transcranial magnetic stimulation and transcranial direct current stimulation. However, the generalization of these interventions to positive clinical outcomes remains unclear and no studies to date have examined interventions on DRD in the context of prevention. Collectively, these findings suggest it would be premature to target DRD for genetically-informed prevention. Indeed, given the evidence of environmental contributions to impulsive DRD, whether genetically-informed secondary prevention would ever be warranted is debatable. Progress in identifying polymorphisms associated with DRD profiles could further clarify the underlying biological systems for pharmacological and neuromodulatory interventions, and, as a qualitatively different risk factor from existing prevention programs, impulsive DRD is worthy of investigation at a more general level as a novel and promising drug abuse prevention target.

Each product was used for the duration of the hospital stay with daily observations for perineal skin condition. Results indicated the spray product and wipe product were comparable in rate of skin breakdown prevention. Findings suggest the wipe product is more cost-effective for use during hospitalization, and the spray product preserves skin integrity over a longer period of time, beyond average hospitalization duration.

  4. An exploratory study of the potential learning benefits for medical students in collaborative drawing: creativity, reflection and ‘critical looking’

    PubMed Central

    2013-01-01

    Background Building on a series of higher educational arts/medicine initiatives, an interdisciplinary drawing module themed on the human body was developed for both year 3 Craft students and year 3 Medicine degree students. This became the subject of a research project exploring how the collaborative approach to drawing adopted on this module impacted on the students’ learning. In this article, emphasis is given to issues thought to have most potential relevance to medical education. Methods Using an ethnographic research design, the methods adopted were: direct observation of all aspects of the module sessions, audio and video recordings and photographs of the sessions, the incorporation of a semi-structured discussion at the end of each session, and anonymous student questionnaires. Results A number of key themes emerged. The complex, phased and multi-sensory nature of the ‘critical looking’ skills developed through the drawing exercises was seen as of potential value in medical education, being proposed as analogous to processes involved in clinical examination and diagnosis. The experience of interdisciplinary collaborative drawing was significant to the students as a creative, participatory and responsive form of learning. The emphasis on the physical experience of drawing and the thematic use of the human body as drawing subject led to reflective discussions about bodily knowledge and understanding. There were indications that students had a meta-cognitive awareness of the learning shifts that had occurred and the sessions provoked constructive self-reflective explorations of pre-professional identity. Conclusions This preliminary study suggests, through the themes identified, that there may be potential learning outcomes for medical students in this model of interdisciplinary collaborative drawing of the human body. Further research is needed to explore their applicability and value to medical education. There is a need to explore in more depth the

    Background The implementation of guidelines for the prevention of Ventilator-associated pneumonia has been shown to have a significant effect in reducing the incidence of VAP. Objective The aim of the present study was to evaluate the implementation of the preventive strategies for VAP in ICUs of university hospitals of Sari, Iran. Materials and Methods This cross-sectional study was carried out in 600 beds/day in the ICUs of university hospitals of Sari from April to June 2012. Sampling was done by availability technique in patients receiving mechanical ventilation in the ICU. The implementation of the preventive measures was assessed by a standard checklist with previously approved validity and reliability. Results The percentage of implementing each of the measures was as follows: sterile suction, 88.44%; semi-recumbent position, 76.8%; oral hygiene, 58.45%; using heat and moisture exchanges (HMEs), 58%; controlling cuff pressure, 46.8%; hand hygiene, 32.8%; using anti-coagulants, 26.8% and physiotherapy, 25.5%. Closed suction system, continuous drainage of subglottic secretions and kinetic beds were not used at all. Conclusion The overall mean percentage of implementing preventive measures was low and required designing integrated guidelines by considering the conditions of the ICUs in each country, as well as educating and encouraging the staffs to use the recommended guidelines.

  6. Direct Numerical Simulations of Reflection-Driven, Reduced MHD Turbulence from the Sun to the Alfvén Critical Point

    Perez, J. C.; Chandran, B. D.

    2013-12-01

    We present direct numerical simulations of inhomogeneous reduced magnetohydrodynamic (RMHD) turbulence between the Sun and the Alfvén critical point. These are the first such simulations that take into account the solar-wind outflow velocity and the radial inhomogeneity of the background solar wind without approximating the nonlinear terms in the governing equations. Our simulation domain is a narrow magnetic flux tube with a square cross section centered on a radial magnetic field line. We impose periodic boundary conditions in the plane perpendicular to the background magnetic field B0. RMHD turbulence is driven by outward-propagating Alfvén waves (z+ fluctuations) launched from the Sun, which undergo partial non-WKB reflection to produce sunward-propagating Alfvén waves (z- fluctuations). Nonlinear interactions between z+ and z- then cause fluctuation energy to cascade from large scales to small scales and dissipate. We present ten simulations with different values of the correlation time τ+c⊙ and perpendicular correlation length L⊥⊙ of outward-propagating Alfvén waves (AWs) at the coronal base. We find that between 15% and 33% of the z+ energy launched into the corona dissipates between the coronal base and Alfvén critical point, which is at rA = 11.1R⊙ in our model solar wind. Between 33% and 40% of this input energy goes into work on the solar-wind outflow, and between 22% and 36% escapes as z+ fluctuations through the simulation boundary at r=rA. Except in the immediate vicinity of r=R⊙, the z× power spectra scale like k⊥-α×, where k⊥ is the wavenumber in the plane perpendicular to B0. In our simulation with the smallest value of τ+c⊙ (~2 min) and largest value of L⊥⊙ (~2×104 km), we find that α+ decreases approximately linearly with increasing ln(r), reaching a value of~1.3 at r=11.1R⊙. Our simulations with larger values of τ+c⊙ exhibit alignment between the contours of constant Φ× and Ω×, where Φ× are the Els

    In November 2008, the JUPITER trial was published in the New England Journal of Medicine. JUPITER is an acronym for Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin. It was an AstraZeneca sponsored randomized double-blind trial comparing rosuvastatin 20 mg with placebo in 17,802 apparently healthy men and women with LDL cholesterol <3.4 mmol/L and elevated C-reactive protein (CRP). The results of the JUPITER trial have been widely publicized, and based on the trial, the main regulatory agencies have approved rosuvastatin for the indication of primary prevention of vascular events. However, the interpretation and clinical implications of the JUPITER trial have been questioned and remain controversial. The objective of this commentary is to evaluate the relevance, design, results, and conclusions of the JUPITER study.

    Alcohol use disorders (AUD) are commonly comorbid with anxiety and mood disorders; however, a strategy for AUD prevention remains unclear in the presence of three competing etiological models that each recommends different high-risk groups. Therefore, the investigation of the three hypotheses in a characteristically unique cohort is critical to identifying pervasive characteristics of AUD that can inform a universal prevention strategy. The current study evaluated the temporality and onset of comorbid AUD and psychiatric disorders in a representative sample of 528 Ohio Army National Guard soldiers using structured clinical interviews from 2009 to 2012. We examined temporality both statistically and graphically to identify patterns that could inform prevention. General estimating equations with dichotomous predictor variables were used to estimate odds ratios between comorbid psychiatric disorders and AUDs. An annualized rate of 13.5 % persons per year was diagnosed with any AUD between 2010 and 2012. About an equal proportion of participants with comorbid psychiatric disorders and AUD initiated the psychiatric disorder prior to the AUD and half initiated the psychiatric disorder after the AUD. Regardless of onset, however, the majority (80 %) AUD initiated during a short interval between the ages of 16 and 23. Focused primary prevention during this narrow age range (16-23 years) may have the greatest potential to reduce population mental health burden of AUD, irrespective of the sequencing of comorbid psychiatric disorder.

    2016-04-01

    The main objectives of this study were to evaluate to what extent variations in herd-level antimicrobial consumption (AMC) can be explained by differences in management practices that are consistently effective in the prevention of (sub)clinical mastitis, on the one hand, and by differences in mastitis treatment strategies, on the other hand. Antimicrobial consumption data were obtained during 2012 and 2013 by "garbage can audits" and expressed as antimicrobial treatment incidences (ATI) for all compounds combined (total ATI) and for the critically important antimicrobials for human health separately. Data on mastitis prevention and control practices were obtained via face-to-face interviews performed during herd visits in March 2013. Some management practices and treatment strategies related to udder health were associated with the total AMC. However, the results demonstrated that implementing effective udder health management practices does not necessarily imply a low AMC and vice versa. Herds participating in a veterinary herd health management program and herds selectively drying off cows used fewer antimicrobials compared with herds not participating in such a program or applying blanket dry-cow therapy. Moreover, herds treating (some) (sub)clinical mastitis cases with intramammary homeopathic substances consumed fewer antimicrobials than herds not applying such homeopathic treatments. Besides these factors, no other direct association was found between effective udder health management practices on the one hand and AMC on the other hand. Also, the use of critically important antimicrobials was only associated with the way in which subclinical mastitis cases were treated. The latter indicates that the AMC of critically important antimicrobials is potentially driven by factors other than those included in this study such as those related to the "mindset" of the veterinarians and their farmers. Future research should therefore aim to unravel the reasoning of

    2007-09-13

    In infectious diseases we can discern a cause and effect chain, which in particular offers the practicable perspectives of prophylaxis and treatment. However, to date we have not been able to control them. Apart from new epidemics, such as those caused by HIV and SARS, long-forgotten scourges like TB are enjoying a comeback. Furthermore, the advances made in clinical medicine mean that induced immunosuppression, for instance as a result of major surgery or organ transplantation, has become a serious problem in intensive care units. The body's natural barriers are breached through medical interventions while, on the other hand, immunocompromising therapeutic agents such as cytostacis and glucocorticoids ensure that invading microorganisms will be able to multiply. Drugs administered as stress ulcus prophylaxis give rise to a shift in the bacterial flora of the throat, thus laying the foundation for a lower respiratory tract infection. With regard to bacterial resistance, antibiotic therapy, especially when used as prophylaxis, results in the bacteria becoming less sensitive to the drugs, while reinforcing selective pressures. The hands of personnel as well as the therapeutic devices ranging from the respirator to the catheter are the chief sources of infection in intensive care units. Disinfection, antibiotic therapy and, possibly, extracorporeal elimination methods can be contemplated to selectively prevent the establishment and multiplication of microorganisms. However, only disinfectants are able to unleash their full destructive might against microbes, especially when used for medical devices that are not amenable to sterilization, even if their subsequent removal and, possibly, the issue of staff hand protection, can be a problem. While it is not easy to furnish proof of a direct link between efficient control and prevention methods and the incidence of infection, there is by now a consensus on the role of hand hygiene and of disinfection of the human body and

    Several promising therapies assessed in the adult critically ill in large, multicenter randomized controlled trials (RCTs) were associated with significantly increased mortality in the intervention arms. Our hypothesis was that there would be wide ranges in sponsorship (industry or not), type(s) of intervention(s), use of DSMBs, presence of interim analyses and early stopping rules, absolute risk increase (ARI), and whether or not adequate prior proof-of-principle Phase II studies were done of RCTs that found increased mortality rates of the intervention compared to control groups. We reviewed RCTs that showed a statistically significant increased mortality rate in the intervention compared to control group(s). We recorded source of sponsorship, sample sizes, types of interventions, mortality rates, ARI (as well as odds ratios, relative risks and number needed to harm), whether there were pre-specified interim analyses and early stopping rules, and whether or not there were prior proof-of-principle (also known as Phase II) RCTs. Ten RCTs (four industry sponsored) of many interventions (high oxygen delivery, diaspirin cross-linked hemoglobin, growth hormone, methylprednisolone, hetastarch, high-frequency oscillation ventilation, intensive insulin, NOS inhibition, and beta-2 adrenergic agonist, TNF-α receptor) included 19,126 patients and were associated with wide ranges of intervention versus control group mortality rates (25.7-59 %, mean 29.9 vs 17-49 %, mean 25 %, respectively) yielding ARIs of 2.6-29 % (mean 5 %). All but two RCTs had pre-specified interim analyses, and seven RCTs were stopped early. All RCTs were preceded by published proof-of-principle RCT(s), two by the same group. Seven interventions (except diaspirin cross-linked hemoglobin and the NOS inhibitor) were available for use clinically at the time of the pivotal RCT. Common, clinically available interventions used in the critically ill were associated with increased mortality in large

Furthermore, when this is viewed in other components of the metabolic syndrome (i.e., the burden of high cholesterol and hypertension), the prevalence of the metabolic syndrome continues to rise in the USA continued challenge is how to deal with this epidemic from a medical and public health standpoint. Community Based Participatory Research (CBPR) is a unique approach and offers a novel perspective for answering this challenge. A critical set of goals for CBPR is to address health disparities and social inequalities while getting community members engaged in all aspects of the research process. Utilizing the West Virginia Diabetes Prevention and Management Program and trained Health Coaches as a model, we discuss topics of consideration related to CBPR, involving trained health coaches, optimizing early adoption of healthy lifestyle behaviors, and enhancing participation. Through careful project planning and design, questions regarding disparities increasing susceptibility and preventive efforts within the community can be addressed successfully. These topics are part of a broader integration of theories such as participatory research, community engagement, and outcomes measurement. The understanding of the pathophysiology and epidemiology of the metabolic syndrome can help frame an appropriate strategy for establishing long-term community-wide changes that promote health. In order to continue to improve investigations for preventing the metabolic syndrome, it will be necessary to have aggressive efforts at the individual and population level for developing culturally sensitive programs that start early and are sustainable in practical environments such as the workplace.

    An improved neutron reflecting supermirror structure comprising a plurality of stacked sets of bilayers of neutron reflecting materials. The improved neutron reflecting supermirror structure is adapted to provide extremely good performance at high incidence angles, i.e. up to four time the critical angle of standard neutron mirror structures. The reflection of neutrons striking the supermirror structure at a high critical angle provides enhanced neutron throughput, and hence more efficient and economical use of neutron sources. One layer of each set of bilayers consist of titanium, and the second layer of each set of bilayers consist of an alloy of nickel with carbon interstitially present in the nickel alloy.

    The mind-body problem lies at the heart of the clinical practice of both psychiatry and psychosomatic medicine. In their recent publication, Schwartz and Wiggins address the question of how to understand life as central to the mind-body problem. Drawing on their own use of the phenomenological method, we propose that the mind-body problem is not resolved by a general, evocative appeal to an all encompassing life-concept, but rather falters precisely at the insurmountable difference between "natural" and a "reflective" experience built into phenomenological method itself. Drawing on the works of phenomenologically oriented thinkers, we describe life as inherently "teleological" without collapsing life with our subjective perspective, or stepping over our epistemological limits. From the phenomenology it can be demonstrated that the hypothetical teleological qualities are a reflective reconstruction modelled on human behavioural structure. PMID:21040525

    Children with intellectual disabilities spend more time in the health-care system than mainstream children. Parents have to learn how to navigate the system by coordinating appointments, understanding the referral process, knowing what services are available, and advocating for those services. This places an incredible amount of responsibility on families. This article is one mother's personal story and reflection about her journey through the Canadian health-care system in Nova Scotia, with her daughter who has an intellectual disability. The reflection identifies moments of tension experienced by a mother and how she was expected to be a medical system navigator, doctor-educator, time manager, and care coordinator and the roles that led to feelings of repression, extreme frustration, and fear. A final discussion offers an analysis of her experience, using concepts from feminist post-structuralism.

    A series of critical experiments were completed in 1962-1965 at Oak Ridge National Laboratory's Critical Experiments Facility in support of the Medium-Power Reactor Experiments (MPRE) program. In the late 1950's efforts were made to study 'power plants for the production of electrical power in space vehicles'. The MPRE program was a part of those efforts and studied the feasibility of a stainless steel system, boiling potassium 1 MW(t), or about 140 kW(e), reactor. The program was carried out in FY 1964, 1965, and 1966. A summary of the program's effort was compiled in 1967. The delayed critical experiments served as a mockup of a small, potassium-cooled space power reactor for validation of reactor calculations and reactor physics methods. Initial experiments, performed in November and December of 1962, consisted of a core of unmoderated 253 stainless steel tubes, each containing 26 UO2 fuel pellets, surrounded by a graphite reflector. Measurements were made to determine critical reflector arrangements, fission-rate distributions, and cadmium ratio distributions. Subsequent experiments used beryllium reflectors and also measured the reactivity for various materials placed in the core. 'The [assemblies were built] on [a] vertical assembly machine so that the movable part was the core and bottom reflector.' The experiment studied within this evaluation was the first of the series and had the 253 fuel tubes packed tightly into a 22.87 cm outside diameter (OD) core tank. Two critical configurations were found by varying the amount of graphite reflector (References 1 and 2). Information for this evaluation was compiled from Reference 1 and 2, reports on subsequent experiments in the series, and the experimental logbook as well as from communication with the experimenter, John T. Mihalczo.

    Objective This paper describes a reflective learning program within a larger curriculum on behavioral and social science that makes use of close reading, written representation of experience, discussion, and textual response. This response may in turn lead to further reflection, representation, and response in a circular pattern. A unique feature of this program is that it pays attention to the representation itself as the pivotal activity within reflective learning. Using the narrative methods that are the hallmark of this program, faculty writings were analyzed to characterize the essential benefits that derive from these practices. Methods In the context of a faculty development seminar on the teaching of behavioral and social sciences in medical curricula, a group of fifteen faculty members wrote brief narratives of reflective learning experiences in which they had made use of the methods described above. Their responses were submitted to iterative close reading and discussion, and potential themes were identified. Results Four themes emerged: writing as attention to self, writing as attention to other, writing as reader/writer contract, and writing as discovery. In each instance, writing provides a new or deepened perspective, and in each case the dividends for the writer are amplified by the narrative skills of those who read, listen, and respond. Conclusions The narrative pedagogy described and modeled herein provides a potentially promising approach to teaching the social, cultural, behavioral, and interpersonal aspects of medical education and practice. Future research will deepen our understanding of the benefits and limitations of this pedagogy and expand our appreciation of its applications. PMID:25272952

The serotonin (5-HT) pathway from the dorsal raphe nucleus (DRN) to the medial prefrontal cortex (mPFC) by CRF-R1 was investigated as a possible target for the prevention of alcohol-heightened aggressive behavior. Male CFW mice that reliably exhibited aggressive behaviors after consuming 1 g/kg of alcohol received systemic or intra-DRN administration of CRF-R1 antagonists, CP-154,526 or MTIP, before a confrontation with a male conspecific. Blockade of DRN CRF-R1 receptors with both antagonists significantly reduced only alcohol-heightened aggression, whereas systemic administration reduced both alcohol-heightened and species-typical aggression. Next, a 5-HT1A agonist, 8-OH-DPAT, was coadministered with CP-154,526 into the DRN to temporarily disrupt 5-HT activity. This manipulation abolished the antiaggressive effects of intra-DRN CP-154,526. In the mPFC, in vivo microdialysis revealed that extracellular 5-HT levels were increased in mice that consumed alcohol and were then injected with CP-154,526, both systemically or intra-DRN. Neither alcohol nor CP-154,526 alone affected 5-HT release in the mPFC. The present results suggest the DRN as a critical site for CRF-R1 to modulate alcohol-heightened aggression via action on the serotonergic DRN-PFC pathway.

    OBJECTIVE To evaluate the new adult Centers for Disease Control and Prevention (CDC) ventilator-associated event (VAE) module in critically ill children and compare with the traditionally used CDC definition for ventilator-associated pneumonia (VAP). DESIGN Retrospective observational study of mechanically ventilated children in a pediatric intensive care unit in Greece January 1-December 31, 2011. METHODS Assessment of new adult CDC VAE module including 3 definition tiers: ventilator-associated condition (VAC), infection-related VAC, and possible/probable ventilator-associated pneumonia (VAE-VAP); comparison with traditional CDC criteria for clinically defined pneumonia in mechanically ventilated children (PNEU-VAP). We recorded Pediatric Risk of Mortality score at admission (PRISM III), number of ventilator-days, and outcome. RESULTS Among 119 patients with mechanical ventilation (median [range] number of ventilator-days, 7 [1-183]), 19 patients experienced VAC. Criteria for VAE-VAP were fulfilled in 12 of 19 patients with VAC (63%). Children with either VAC or VAE-VAP were on ventilation more days than patients without these conditions (16.5 vs 5 d, P=.0006 and 18 vs 5 d, P<.001, respectively), whereas PRISM-III score was similar between them. Mortality was significant higher in patients with new VAE-VAP definition (50%), but not in patients with VAC (31.6%), than the patients without new VAE-VAP (14%, P=.007) or VAC (15%, P=.1), respectively. No significant association was found between PNEU-VAP and death. Incidences of PNEU-VAP and VAE-VAP were similar, but the agreement was poor. CONCLUSIONS VAE-VAP and PNEU-VAP found similar prevalence in critically ill children but with poor agreement. However, excess of death was significantly associated only with VAE-VAP.

    A complex gravity wave event was observed from 04:30 to 08:10 UTC on 16 January 2015 by a narrow-band sodium lidar and an all-sky airglow imager located at Andes Lidar Observatory (ALO) in Cerro Pachón (30.25°S, 70.73°W), Chile. The gravity wave packet had a period of 18-35 min and a horizontal wavelength of about 40-50 km. Strong enhancements of the vertical wind perturbation, exceeding 10 m s-1, were found at ˜90 km and ˜103 km, consistent with nearly evanescent wave behavior near a reflection layer. A reduction in vertical wavelength was found as the phase speed approached the background wind speed near ˜93 km. A distinct three-layered structure was observed in the lidar data due to refraction of the wave packet. A fully nonlinear model was used to simulate this event, which successfully reproduced the amplitudes and layered structure seen in observations. The model results provide dynamical insight, suggesting that a double reflection occurring at two separate heights caused the large vertical wind amplitudes, while the three-layered structure in the temperature perturbation was a result of relatively stable regions at those altitudes. The event provides a clear perspective on the filtering processes to which short-period, small-scale gravity waves are subject in mesosphere and lower thermosphere.

    A series of critical experiments were completed in 1962-1965 at Oak Ridge National Laboratory’s Critical Experiments Facility in support of the Medium-Power Reactor Experiments (MPRE) program. In the late 1950’s efforts were made to study “power plants for the production of electrical power in space vehicles”. The MPRE program was a part of those efforts and studied the feasibility of a stainless steel system, boiling potassium 1 MW(t), or about 140 kW(e), reactor. The program was carried out in [fiscal years] 1964, 1965, and 1966. A summary of the program’s effort was compiled in 1967. The delayed critical experiments were a mockup of a small, potassium-cooled space power reactor for validation of reactor calculations and reactor physics methods. Initial experiments, performed in November and December of 1962, consisted of a core of 253 unmoderated stainless steel tubes, each containing 26 UO2 fuel pellets, surrounded by a graphite reflector. Measurements were made to determine critical reflector arrangements, fission-rate distributions, and cadmium ratio distributions. Subsequent experiments used beryllium reflectors and also measured the reactivity for various materials placed in the core. “The [assemblies were built] on [a] vertical assembly machine so that the movable part was the core and bottom reflector.” The first experiment in the series was evaluated in HEU-COMP-FAST-001. It had the 253 fuel tubes packed tightly into a 22.87 cm outside diameter (OD) core tank (References 1 and 2). The second experiment in the series, performed in early 1963, which is studied in this evaluation, had the 253 fuel tubes at a 1.506-cm triangular lattice in a 25.96 cm OD core tank and graphite reflectors on all sides. The experiment has been determined to represent an acceptable benchmark experiment. Information for this evaluation was compiled from published reports on all three parts of the experimental series (Reference 1-5) and the experimental logbook as

    This paper reports a retrospective study of a Senior Lecturer in Nursing Studies experience of supervising a student teacher who, as part of her teaching placement experience, utilised 'Critically Reflective Analysis of an Educational Event' as a means to assess her teaching in the practice setting. The Senior Lecturer and student nurse teacher used an external 'advisor' to facilitate their meta-reflection on the theoretical perspectives that informed the process in which they were engaged. The paper raises the following questions for consideration--What is the link between ability to reflect and quality of practice? Is it possible to utilise reflective tutorials as a means of assessing professional competence whilst at the same time encouraging personal and professional development? Is the ability to reflect on practice dependent on the context? Should we assume that all practitioners have the necessary skills to supervise students in practice and what preparation and support is needed? The paper demonstrates that by introducing 'Critically Reflective Analysis of an Education Event' into the student teachers' curriculum the role of both supervisor and student teacher was challenged and changed. The paper also demonstrates that reflective tutorials are not wholly a retrospective business. They are creative, or recreative of a teaching experience, as well as to some extent representing it. Finally, even if one cannot speak in Kuhnian parlance, of a conceptual revolution, it would seem legitimate to say, in Schon's terms, that the contextual frame in which professional problems are addressed has undergone significant change.

    The dual-use issue is often framed as a series of paralyzing 'dilemmas' facing the scientific community as well as institutions which support innovation. While this conceptualization of the dual-use issue can be useful in certain contexts (such as in awareness-raising and as part of educational activities directed at the scientific community) its usefulness is more limited when reflecting on the governance and politics of the dual-use issue. Within this paper, key shortcomings of the dilemma framing are outlined. It is argued that many of the issues raised in the most recent debates about 'dual-use' bird flu research remain unresolved. This includes questions about the trajectories of certain lines of research, as well as broader trends in the practice and governance of science. This leads to difficult questions about current approaches to the dual-use issue within the US, as well as internationally.

    Tom G. K. Bryce and Stephen P. Day's (2013) original article on scepticism and doubt in science education explores the context of citizens' attitudes towards the complexities and uncertainties of global issues, namely global warming. This response aims to stimulate reflection on some of the implicit assumptions underpinning the relationships between science, technology and the public. I argue that an underestimation of the political and ethical dimensions of science and technology limits the possibilities for education to set the agenda for citizens' participation in science and technological matters. Drawing on Sheila Jasanoff's model of co-production, this paper proposes a radical re-affirmation of the aims and purposes of science education to embrace a multiplicity of disciplines, narratives and ways of knowing in science, technology and society issues.

    Grace Reid and the late Stephen Norris argue in this issue the urgent need for widespread Science Media Education (SME) as an integral part of formal and informal science education. SME is to achieve two goals: First, allow learners to critically evaluate any media as a source for scientific information by understanding the socio-economic and socio-cultural context of how and why news and entertainment media are created, and secondly, utilize media as a legitimate and productive source for science education and science learning. While laudable, I will argue that SME as an integral part of STEM education is unrealistic, and offer instead that the broader concept of Information Literacy might be more easily achieved within the current strong movement to conceptualize STEM education via science and engineering practices and within the broad goals of strengthening learners' 21st century skills.

  3. Critical reflections on evolutionary psychology and sexual selection theory as explanatory account of emergence of sex differences in psychopathology: comment on Martel (2013).

    2013-11-01

    Martel (2013) proposed a metatheory, based on sexual selection theory and broad evolutionary psychological (EP) principles, to account for well-known sex differences in the emergence of common behavioral and certain internalizing disorders across childhood and adolescence, respectively. In this comment, I first enumerate several strengths and then offer 2 primary critiques about Martel's proposal. Martel provides an exceptional, integrative review that organizes several disparate literatures that hold promise to enhance understanding of such sex differences. At the same time, I raise critical questions regarding EP generally, and sexual selection theory specifically, as the metatheoretical framework chosen to bind together these different influences and mechanisms as drivers of the sex difference in different psychopathologies. Indeed, it is not clear that EP is necessary--nor does it provide unique explanatory power-to explicate the emergence of sex differences in internalizing and externalizing disorders among youth. Moreover, Martel's EP-based proposal pertains to adolescent-onset depression and social phobia but does not provide an explanation for known sex differences in other common childhood-onset and early adult-onset anxiety disorders.

    2007-01-01

    Background Viewed through the micro focus of an interpretive lens, medical anthropology remains mystified because interpretivist explanations seriously downplay the given context in which individual health seeking-behaviours occur. This paper draws upon both the interpretivist and political economy perspectives to reflect on the ethno medical practices within the Korean-Australian community in Sydney. Methods We draw on research data collected between 1995 and 1997 for an earlier study of the use of biomedical and traditional medicine by Korean-Australians in Sydney. A total of 120 interviews were conducted with a range of participants, including biomedical doctors, traditional health professionals, Korean community leaders and Korean migrants representing a range of socio-economic backgrounds and migration patterns. Results and Discussion First, the paper highlights the extent to which the social location of migrants in a host society alters or restructures their initial cultural practices they bring with them. Second, taking hanbang medicine in the Korean-Australian community as an illustrative case, the paper explores the transformation of the dominant biomedicine in Australia as a result of the influx of ethnomedicine in the era of global capitalism and global movement. Conclusion In seeking to explain the popularity and supply of alternative health care, it is important to go beyond the culture of each kind of health care itself and to take into consideration the changes occurring at societal, national and global levels as well as consequential individual response to the changes. New social conditions influence the choice of health care methods, including herbal/alternative medicine, health foods and what are often called New Age therapies. PMID:17201916

    Little is known about the cost-benefit of soft silicone foam dressings in pressure ulcer (PU) prevention among critically ill patients in the emergency department (ED) and intensive care unit (ICU). A randomised controlled trial to assess the efficacy of soft silicone foam dressings in preventing sacral and heel PUs was undertaken among 440 critically ill patients in an acute care hospital. Participants were randomly allocated either to an intervention group with prophylactic dressings applied to the sacrum and heels in the ED and changed every 3 days in the ICU or to a control group with standard PU prevention care provided during their ED and ICU stay. The results showed a significant reduction of PU incidence rates in the intervention group (P = 0·001). The intervention cost was estimated to be AU$36·61 per person based on an intention-to-treat analysis, but this was offset by lower downstream costs associated with PU treatment (AU$1103·52). Therefore, the average net cost of the intervention was lower than that of the control (AU$70·82 versus AU$144·56). We conclude that the use of soft silicone multilayered foam dressings to prevent sacral and heel PUs among critically ill patients results in cost savings in the acute care hospital.

    The prevention of hospital acquired pressure ulcers in critically ill patients remains a significant clinical challenge. The aim of this trial was to investigate the effectiveness of multi-layered soft silicone foam dressings in preventing intensive care unit (ICU) pressure ulcers when applied in the emergency department to 440 trauma and critically ill patients. Intervention group patients (n = 219) had Mepilex(®) Border Sacrum and Mepilex(®) Heel dressings applied in the emergency department and maintained throughout their ICU stay. Results revealed that there were significantly fewer patients with pressure ulcers in the intervention group compared to the control group (5 versus 20, P = 0·001). This represented a 10% difference in incidence between the groups (3·1% versus 13·1%) and a number needed to treat of ten patients to prevent one pressure ulcer. Overall there were fewer sacral (2 versus 8, P = 0·05) and heel pressure ulcers (5 versus 19, P = 0·002) and pressure injuries overall (7 versus 27, P = 0·002) in interventions than in controls. The time to injury survival analysis indicated that intervention group patients had a hazard ratio of 0·19 (P = 0·002) compared to control group patients. We conclude that multi-layered soft silicone foam dressings are effective in preventing pressure ulcers in critically ill patients when applied in the emergency department prior to ICU transfer.

    Cadmium ratios were measured with enriched uranium metal foils at various locations in the assembly with the fuel tube at the 1.506-cm spacing. They are described in the following subsections. The experiment configuration was the same as the first critical configuration described in HEU-COMP-FAST-004 (Case 1). The experimenter placed 0.75-cm-diameter × 0.010-cm-thick 93.15%-235U-enriched uranium metal foils with and without 0.051-cm-thick cadmium covers at various locations in the core and top reflector. One part of the cadmium cover was cupshape and contained the uranium foil. The other part was a lid that fit over the exposed side of the foil when it was in the cup shaped section of the cover. As can be seen in the logbook, two runs were required to obtain all the measurements necessary for the cadmium ratio. The bare foil measurements within the top reflector were run first as part of the axial foil activation measurements. The results of this run are used for both the axial activation results and the cadmium ratios. Cadmium covered foils were then placed at the same location through the top reflector in a different run. Three pairs of bare and cadmium covered foils were also placed through the core tank. One pair was placed at the axial center of a fuel tube 11.35 cm from the center of the core. Two pairs of foils were placed on top of fuel tubes 3.02 and 12.06 cm from the center of the core. The activation of the uranium metal foils was measured after removal from the assembly using two lead shielded NaI scintillation detectors as follows. The NaI scintillators were carefully matched and had detection efficiencies for counting delayed-fission-product gamma rays with energies above 250 KeV within 5%. In all foil activation measurements, one foil at a specific location was used as a normalizing foil to remove the effects of the decay of fission products during the counting measurements with the NaI detectors.

In this response to Grimes' article, I endeavor to answer this question, considering the author's story as both a space for unpacking and the complex intersection of identity, teaching and learning and as an effort to name herself in the midst of such complexity. Specifically, I address the raced, gendered, classed nature of the relationships that Grimes' suggests facilitate science learning in her classroom, asking "What is gained or lost when students' success is attributed to such relationships?"

    The authors review the philosophical trend known as postmodernism and the way it has influenced a part of psychoanalytic thought, concluding with some comments on the qualities and shortcomings of the new developments. The authors consider the origins and the cultural and aesthetic-philosophical meaning of postmodernism, identifying some key concepts such as deconstructionism, the disappearance of the 'individual subject' and individual identity, and the rejection of 'in-depth' models of psychoanalysis. Then they examine various, wide-ranging developments in psychoanalytic thought and treatment. They review the intersubjective field in psychoanalysis, especially in the USA, and then explore whether the underlying lack of truth to be discovered, stressed by these 'new view' statements, or the fact that the 'truth' only exists in linguistic-narrative constructions is consistent with basic analytic concepts such as the unconscious, phantasy, transference and countertransference, which recall the tri-dimensional nature of inner psychic reality. The psychoanalytic process is a condition activated through a bond that is able to hold and contain the relationship of the analytic couple and the patient's unconscious world and not through hermeneutic or narrative constructions.

    As in other countries worldwide, adults with severe mental illness (SMI) in Brazil are disproportionately infected with HIV relative to the general population. Brazilian psychiatric facilities lack tested HIV prevention interventions. To adapt existing interventions, developed only in the U.S., we conducted targeted ethnography with adults with SMI and staff from two psychiatric institutions in Brazil. We sought to characterize individual, institutional, and interpersonal factors that may affect HIV risk behavior in this population. We conducted 350 hours of ethnographic field observations in two mental health service settings in Rio de Janeiro, and 9 focus groups (n = 72) and 16 key-informant interviews with patients and staff in these settings. Data comprised field notes and audiotapes of all exchanges, which were transcribed, coded, and systematically analyzed. The ethnography characterized the institutional culture and identified: 1) patients’ risk behaviors; 2) the institutional setting; 3) intervention content; and 4) intervention format and delivery strategies. Targeted ethnography also illuminated broader contextual issues for development and implementation of HIV prevention interventions for adults with SMI in Brazil, including an institutional culture that did not systematically address patients’ sexual behavior, sexual health, or HIV sexual risk, yet strongly impacted the structure of patients’ sexual networks. Further, ethnography identified the Brazilian concept of “social responsibility” as important to prevention work with psychiatric patients. Targeted ethnography with adults with SMI and institutional staff provided information critical to the adaptation of tested U.S. HIV prevention interventions from the US for Brazilians with SMI.

    This article explores the use of reflection and critical thinking during a return-to-practice programme, demonstrating both concepts and their value in developing insight. The aim of the article is to provide insight into a learner's reflection about nursing older people and encourage nurses to reflect and think critically about their own practice, which is a requirement of forthcoming revalidation. Lessons learned as a result of reflection must be demonstrated in order for registered nurses to revalidate. Reflection and insight gained from critical thinking can have a positive effect on individual nurses and the quality of patient care they provide.

    The category of community health worker applied within the context of health intervention trials has been promoted as a cost-effective approach to meeting study objectives across large populations, relying on the promotion of the concept of ‘com-munity belonging’ to encourage altruistic volunteerism from community members to promote health. This community-based category of individuals is recruited to facilitate externally driven priorities defined by large research teams, outside of the target research environment. An externally defined intervention is then ‘brought to’ the community through locally recruited community volunteers who form a bridge between the researchers and participants. The specific role of these workers is context-driven and responsive to the needs of the intervention. This paper is based on the findings from an annual evaluation of community health worker performance employed as community counsellors to deliver semi-supervised HIV self-testing (HIVST) at community level of a large HIV/TB intervention trial conducted in urban Blantyre, Malawi. A performance evaluation was conducted to appraise individual service delivery and assess achievements in meeting pre-defined targets for uptake of HIVST with the aim of improving overall uptake of HIVST. Through an empirical ‘evaluation of the evaluation’ this paper critically reflects on the position of the community volunteer through the analytical lens of ‘failure’, exploring the tensions in communication and interpretation of intervention delivery between researchers and community volunteers and the differing perspectives on defining failure. It is concluded that community interventions should be developed in collaboration with the population and that information guiding success should be clearly defined. PMID:26762610

  9. A feasible strategy for preventing blood clots in critically ill patients with acute kidney injury (FBI): study protocol for a randomized controlled trial

    PubMed Central

    2014-01-01

    Background Previous pharmacokinetic trials suggested that 40 mg subcutaneous enoxaparin once daily provided inadequate thromboprophylaxis for intensive care unit patients. Critically ill patients with acute kidney injury are at increased risk of venous thromboembolism and yet are often excluded from these trials. We hypothesized that for critically ill patients with acute kidney injury receiving continuous renal replacement therapy, a dose of 1 mg/kg enoxaparin subcutaneously once daily would improve thromboprophylaxis without increasing the risk of bleeding. In addition, we seek to utilize urine output prior to discontinuing dialysis, and low neutrophil gelatinase-associated lipocalin in dialysis-free intervals, as markers of renal recovery. Methods/Design In a multicenter, double-blind randomized controlled trial in progress at three intensive care units across Denmark, we randomly assign eligible critically ill adults with acute kidney injury into a treatment (1 mg/kg enoxaparin subcutaneously once daily) or control arm (40 mg enoxaparin subcutaneously once daily) upon commencement of continuous renal replacement therapy. We calculated that with 133 patients in each group, the study would have 80% power to show a 40% reduction in the relative risk of venous thromboembolism with 1 mg/kg enoxaparin, at a two-sided alpha level of 0.05. An interim analysis will be conducted after the first 67 patients have been included in each group. Enrolment began in March 2013, and will continue for two years. The primary outcome is the occurrence of venous thromboembolism. Secondary outcomes include anti-factor Xa activity, bleeding, heparin-induced thrombocytopenia, filter lifespan, length of stay, ventilator free days, and mortality. We will also monitor neutrophil gelatinase-associated lipocalin and urine volume to determine whether they can be used as prognostic factors for renal recovery.

The modeling of soil and vegetation surfaces has been emphasized with a gradual increase in the complexity of the media geometries treated. Pragmatic problems involved in the combined modeling of soil, vegetation, and atmospheric effects have been of interest and one of the objectives has been to describe the canopy reflectance problem in a classical radiative transfer sense permitting easier inclusion of our work by other workers in the radiative transfer field.

    Biofilm formation leads to the failure of antimicrobial therapy. Thus, biofilm prevention is a desirable goal of antimicrobial research. In this study, the efficacy of antibiotics (doxycycline, oxacillin and rifampicin) in preventing Staphylococcus aureus biofilms was investigated using Microtiter Well Plates (MWP) and Drip Flow Reactors (DFR), two models characterized by the absence and the presence of a continuous flow of nutrients, respectively. Planktonic culture of S. aureus was exposed to antibiotics for one hour followed by 24 hours incubation with fresh nutrients in MWP or continuous flow of nutrients in DFR. The DFR grown biofilms were significantly more tolerant to the antibiotics than those grown in MWP without the continuous flow. The differences in log reductions (LR) between the two models could not be attributed to differences in the cell density, the planktonic inoculum concentration or the surface-area-to-volume ratios. However, eliminating the flow in the DFR significantly restored the antibiotic susceptibility. These findings demonstrate the importance of considering differences between experimental conditions in different model systems, particularly the flow of nutrients, when performing anti-biofilm efficacy evaluations. Biofilm antibiotic efficacy studies should be assessed using various models and more importantly, in a model mimicking conditions of its clinical application. PMID:28252025

    Periodontal disease (Periodontitis) is a serious disease that affects a majority of adult Americans and is associated with other systemic diseases, including diabetes, rheumatoid arthritis, and other inflammatory diseases. While great efforts have been devoted toward understanding the pathogenesis of periodontitis, there remains a pressing need for developing potent therapeutic strategies for targeting this pervasive and destructive disease. In this study, we utilized novel adeno-associated virus (AAV)-mediated Atp6v1c1 knockdown gene therapy to treat bone erosion and inflammatory caused by periodontitis in mouse model. Atp6v1c1 is a subunit of the V-ATPase complex and regulator of the assembly of the V0 and V1 domains of the V-ATPase complex. We demonstrated previously that Atp6v1c1 has an essential function in osteoclast mediated bone resorption. We hypothesized that Atp6v1c1 may be an ideal target to prevent the bone erosion and inflammation caused by periodontitis. To test the hypothesis, we employed AAV RNAi knockdown of Atp6v1c1 gene expression to prevent bone erosion and gingival inflammation simultaneously. We found that lesion-specific injection of AAV-shRNA-Atp6v1c1 into the periodontal disease lesions protected against bone erosion (>85%) and gingival inflammation caused by P. gingivalis W50 infection. AAV-mediated Atp6v1c1 knockdown dramatically reduced osteoclast numbers and inhibited the infiltration of dendritic cells and macrophages in the bacteria-induced inflammatory lesions in periodontitis. Silencing of Atp6v1c1 expression also prevented the expressions of osteoclast-related genes and pro-inflammatory cytokine genes. Our data suggests that AAV-shRNA-Atp6v1c1 treatment can significantly attenuate the bone erosion and inflammation caused by periodontitis, indicating the dual function of AAV-shRNA-Atp6v1c1 as an inhibitor of bone erosion mediated by osteoclasts, and as an inhibitor of inflammation through down-regulation of pro

    The nursing practice is described as a scientific practice, but also as a practice where caring is important. The purpose of nursing education is to provide competent nursing practitioners. This implies that future practitioners must have both critical analytical thinking abilities, as well as empathy and moral values. Reflective thinking could probably accommodate these thinking skills. It seems that the facilitation of reflective thinking skills is essential in nursing education. The research question that is relevant in this context is: "What is reflective thinking?" The purpose of this article is to report on the concept analysis of reflective thinking and in particular on the connotative meaning (critical attributes) thereof. The method used to perform the concept analysis is based on the original method of Wilson (1987) as described by Walker & Avant (1995). As part of the concept analysis the connotations (critical attributes) are identified, reduced and organized into three categories, namely pre-requisites, processes and outcomes. A model case is described which confirms the essential critical attributes of reflective thinking. Finally a theoretical definition of reflective thinking is derived and reads as follows: Reflective thinking is a cyclic, hierarchical and interactive construction process. It is initiated, extended and continued because of personal cognitive-affective interaction (individual dimension) as well as interaction with the social environment (social dimension). to realize reflective thinking, a level of internalization on the cognitive and affective domain is required. The result of reflective thinking is a integrated framework of knowledge (meaningful learning) and a internalized value system providing a new perspective on and better understanding of a problem. Reflective thinking further leads to more effective decision making- and problem solving skills.

    Medical devices have been identified as an extrinsic risk factor for development of pressure injuries, with as many as 30% to 70% of medical device-related pressure injuries resulting from respiratory equipment. This article describes a quality improvement project undertaken to reduce the occurrence of respiratory device-related pressure injuries in a critically care unit. Multiple actions were implemented to achieve this goal. Respiratory therapists were trained to document occurrences on a daily basis, and apparent cause analyses were conducted on each occurrence. An interdisciplinary team conducted biweekly rounds on patients with respiratory devices and consulted other professionals as indicated. Nurses and respiratory therapists attended an evidence-based, collaborative, educational offering and completed a measure of team functioning before the program and at the end of the study period. The occurrence rates of respiratory device-related pressure injuries were reduced over the project period, and these changes were sustained over the subsequent 12 months.

    This randomized controlled trial study aims to investigate the efficacy of an early psychological intervention called EMDR-RE compared to Critical Incident Stress Debriefing on 60 victims of workplace violence, which were divided into three groups: 'EMDR-RE' (n = 19), 'CISD' (n = 23), and 'delayed EMDR-RE' (n = 18). EMDR-RE and CISD took place 48 hours after the event, whilst third intervention was delayed by an additional 48 hours. Results showed that after 3 months PCLS and SUDS scores were significantly lower with EMDR-RE and delayed EMDR-RE compared to CISD. After 48 hours and 3 months, none of the EMDR-RE-treated victims showed PTSD symptoms.

    Introduction Survivors of critical illness experience multidimensional disabilities that reduce quality of life, and 25–30% require unplanned hospital readmission within 3 months following index hospitalisation. We aim to understand factors associated with unplanned readmission; develop a risk model to identify intensive care unit (ICU) survivors at highest readmission risk; understand the modifiable and non-modifiable readmission drivers; and develop a risk assessment tool for identifying patients and areas for early intervention. Methods and analysis We will use mixed methods with concurrent data collection. Quantitative data will comprise linked healthcare records for adult Scottish residents requiring ICU admission (1 January 2000–31 December 2013) who survived to hospital discharge. The outcome will be unplanned emergency readmission within 90 days of index hospital discharge. Exposures will include pre-ICU demographic data, comorbidities and health status, and critical illness variables representing illness severity. Regression analyses will be used to identify factors associated with increased readmission risk, and to develop and validate a risk prediction model. Qualitative data will comprise recorded/transcribed interviews with up to 60 patients and carers recently experiencing unplanned readmissions in three health board regions. A deductive and inductive thematic analysis will be used to identify factors contributing to readmissions and how they may interact. Through iterative triangulation of quantitative and qualitative data, we will develop a construct/taxonomy that captures reasons and drivers for unplanned readmission. We will validate and further refine this in focus groups with patients/carers who experienced readmissions in six Scottish health board regions, and in consultation with an independent expert group. A tool will be developed to screen for ICU survivors at risk of readmission and inform anticipatory interventions. Ethics and

    Critical thinking and writing are skills that are not easy to acquire. The term 'critical' is used differently in social and clinical contexts. Nursing students need time to master the inquisitive and ruminative aspects of critical thinking that are required in academic environments. This article outlines what is meant by critical thinking in academic settings, in relation to both theory and reflective practice. It explains how the focus of a question affects the sort of critical thinking required and offers two taxonomies of learning, to which students can refer when analysing essay requirements. The article concludes with examples of analytical writing in reference to theory and reflective practice.

    The continuous shrinkage of critical dimensions has driven ArF lithography to resolve very small features and ever thinner resist films to prevent pattern collapse. Also importance of hardmask technology is becoming increasingly evident as the demand for both the critical dimension control and sufficient thickness of etch mask. We have developed a silicon based hardmask prepared by plasma-enhanced chemical vapor deposition (PECVD) to match organic anti-reflective coating (ARC). The ordinary single dielectric ARC or organic ARC is very sensitivity to the substrate topology. Dual ARC (dielectric ARC + organic ARC) perform a less CD variation than single ARC. In addition, this material can serve as an effective hardmask etch barrier during the plasma etch. The most advantage of Dual ARC is that we have good critical dimension uniformity (CDU) regardless of substrate thickness variation.

    The specular neutron reflectivity is a technique enabling the measurement of neutron scattering length density profile perpendicular to the plane of a surface or an interface, and thereby the profile of chemical composition. The characteristic sizes that are probed range from around 5 Å up 5000 Å. It is a scattering technique that averages information on the entire surface and it is therefore not possible to obtain information within the plane of the interface. The specific properties of neutrons (possibility of tuning the contrast by isotopic substitution, sensitivity to magnetism, negligible absorption, low energy of the incident neutrons) makes it particularly interesting in the fields of soft matter, biophysics and magnetic thin films. This course is a basic introduction to the technique and does not address the magnetic reflectivity. It is composed of three parts describing respectively its principle and its formalism, the experimental aspects of the method (spectrometers, samples) and two examples related to the materials for energy.

  20. Toward critical bioethics.

    PubMed

    Árnason, Vilhjálmur

    2015-04-01

    This article deals with the question as to what makes bioethics a critical discipline. It considers different senses of criticism and evaluates their strengths and weaknesses. A primary method in bioethics as a philosophical discipline is critical thinking, which implies critical evaluation of concepts, positions, and arguments. It is argued that the type of analytical criticism that restricts its critical role to critical thinking of this type often suffers from other intellectual flaws. Three examples are taken to demonstrate this: premature criticism, uncritical self-understanding of theoretical assumptions, and narrow framing of bioethical issues. Such flaws can lead both to unfair treatment of authors and to uncritical discussion of topics. In this context, the article makes use of Häyry's analysis of different rationalities in bioethical approaches and argues for the need to recognize the importance of communicative rationality for critical bioethics. A radically different critical approach in bioethics, rooted in social theory, focuses on analyses of power relations neglected in mainstream critical thinking. It is argued that, although this kind of criticism provides an important alternative in bioethics, it suffers from other shortcomings that are rooted in a lack of normative dimensions. In order to complement these approaches and counter their shortcomings, there is a need for a bioethics enlightened by critical hermeneutics. Such hermeneutic bioethics is aware of its own assumptions, places the issues in a wide context, and reflects critically on the power relations that stand in the way of understanding them. Moreover, such an approach is dialogical, which provides both a critical exercise of speech and a normative dimension implied in the free exchange of reasons and arguments. This discussion is framed by Hedgecoe's argument that critical bioethics needs four elements: to be empirically rooted, theory challenging, reflexive, and politely skeptical.

    Although a universally accepted definition of critical thinking has yet to be determined, there is much discussion in the literature about its meaning and, in particular, how it can be expressed in professional nursing practice. The simultaneous use of related terms such as reflective thinking, problem solving and clinical decision-making contributes to the lack of clarity around exactly what critical thinking is and, subsequently, how it can be taught and evaluated in the clinical setting. The purpose of this article is to provide an overview of the various components of critical thinking and to discuss barriers, facilitators and strategies that can enhance nurses' attainment of this core competency. Few would argue that registered nurses today must be able to think critically in order to effectively communicate a nursing perspective that reflects a meaningful clinical grasp and preparedness to act.

    Background. Methicillin-resistant Staphylococcus aureus (MRSA) colonization is a predictor of subsequent infection in hospitalized adults. The risk of subsequent MRSA infections in hospitalized children colonized with MRSA is unknown. Methods. Children admitted to an academic medical center’s pediatric intensive care unit between March 2007 and March 2010 were included in the study. Anterior naris swabs were cultured to identify children with MRSA colonization at admission. Laboratory databases were queried and National Healthcare Safety Network definitions applied to identify patients with MRSA infections during their hospitalization or after discharge. Results. The MRSA admission prevalence among 3140 children was 4.9%. Overall, 56 children (1.8%) developed an MRSA infection, including 13 (8.5%) colonized on admission and 43 (1.4%) not colonized on admission (relative risk [RR], 5.9; 95% confidence interval [CI], 3.4–10.1). Of those, 10 children (0.3%) developed an MRSA infection during their hospitalization, including 3 of 153 children (1.9%) colonized on admission and 7 of 2987 children (0.2%) not colonized on admission (RR, 8.4; 95% CI, 2.7–25.8). African-Americans and those with public health insurance were more likely to get a subsequent infection (P < .01 and P = .03, respectively). We found that 15 children acquired MRSA colonization in the pediatric intensive care unit, and 7 (47%) developed a subsequent MRSA infection. Conclusions. MRSA colonization is a risk factor for subsequent MRSA infection in children. Although MRSA colonized children may have lower risks of subsequent infection than adults, children who acquire MRSA in the hospital have similarly high rates of infection. Preventing transmission of MRSA in hospitalized children should remain a priority. PMID:21878424

    The nebula Messier 78 takes centre stage in this image taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile, while the stars powering the bright display take a backseat. The brilliant starlight ricochets off dust particles in the nebula, illuminating it with scattered blue light. Igor Chekalin was the overall winner of ESO's Hidden Treasures 2010 astrophotography competition with his image of this stunning object. Messier 78 is a fine example of a reflection nebula. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionise the gas to make it glow - its dust particles simply reflect the starlight that falls on them. Despite this, Messier 78 can easily be observed with a small telescope, being one of the brightest reflection nebulae in the sky. It lies about 1350 light-years away in the constellation of Orion (The Hunter) and can be found northeast of the easternmost star of Orion's belt. This new image of Messier 78 from the MPG/ESO 2.2-metre telescope at the La Silla Observatory is based on data selected by Igor Chekalin in his winning entry to the Hidden Treasures competition [1]. The pale blue tint seen in the nebula in this picture is an accurate representation of its dominant colour. Blue hues are commonly seen in reflection nebulae because of the way the starlight is scattered by the tiny dust particles that they contain: the shorter wavelength of blue light is scattered more efficiently than the longer wavelength red light. This image contains many other striking features apart from the glowing nebula. A thick band of obscuring dust stretches across the image from the upper left to the lower right, blocking the light from background stars. In the bottom right corner, many curious pink structures are also visible, which are created by jets of material being ejected from stars that have recently formed and are still buried deep in dust clouds.

    Gedalin, M.

    2016-11-01

    The dependence of ion dynamics on the cross-shock potential and upstream βi in low-Mach number marginally critical shocks is studied using advanced test particle analysis,. The directly transmitted ions provide the main contribution to the downstream ion pressure. The fraction of reflected ions increases with the increase of the cross-shock potential and βi. This fraction is small and their contribution to the downstream ion pressure is negligible in marginally critical shocks. A population of quasi-reflected ions is identified. These ions make a loop inside the ramp and do not appear upstream. They acquire energies comparable to the energies of the true reflected ions, are observed as a halo in the downstream ion distribution, and contribute significantly to the downstream pressure. Thus, the transmitted and quasi-reflected ions shape the downstream magnetic profile. At higher cross-shock potentials and βi the reflected ions cause formation of a magnetic dip just ahead of the ramp. A small fraction of ions are multiply reflected at the shock front. All these ions escape into the upstream region and all escaping ions are mutliply reflected.

    2010-09-01

    The further increase of allergies in industrialized countries demands evidence-based measures of primary prevention. The recommendations as published in the guideline of 2004 were updated and consented on the basis of a systematic literature search. Evidence from the period February 2003-May 2008 was searched in the electronic databases Cochrane and MEDLINE as well as in reference lists of recent reviews and by contacting experts. The retrieved citations were screened for relevance first by title and abstract and in a second step as full paper. Levels of evidence were assigned to each included study and the methodological quality of the studies was assessed as high or low. Finally the revised recommendations were formally consented (nominal group process) by representatives of relevant societies and organizations including a self-help group. Of originally 4556 hits, 217 studies (4 Cochrane Reviews, 14 meta-analyses, 19 randomized controlled trials, 135 cohort and 45 case-control studies) were included and critically appraised. Grossly unchanged remained the recommendations on avoiding environmental tobacco smoke, breast-feeding over 4 months (alternatively hypoallergenic formulas for children at risk), avoiding a mold-promoting indoor climate, vaccination according to current recommendations, and avoidance of furry pets (especially cats) in children at risk. The recommendation on reducing the house dust mite allergen exposure as a measure of primary prevention was omitted and the impact of a delayed introduction of supplementary food was reduced. New recommendations were adopted concerning fish consumption (during pregnancy / breast-feeding and as supplementary food in the first year), avoidance of overweight, and reducing the exposure to indoor and outdoor air pollutants. The revision of this guideline on a profound evidence basis led to (1) a confirmation of existing recommendations, (2) substantial revisions, and (3) new recommendations. Thereby it is possible

    Introduction Critical technological advances have yielded a toolkit of HIV prevention strategies. This literature review sought to provide contextual and historical reflection needed to bridge the conceptual gap between clinical efficacy and community effectiveness (i.e. knowledge and usage) of existing HIV prevention options, especially in resource-poor settings. Methods Between January 2015 and October 2015, we reviewed scholarly and grey literatures to define treatment literacy and health literacy and assess the current need for literacy related to HIV prevention. The review included searches in electronic databases including MEDLINE, PsycINFO, PubMed, and Google Scholar. Permutations of the following search terms were used: “treatment literacy,” “treatment education,” “health literacy,” and “prevention literacy.” Through an iterative process of analyses and searches, titles and/or abstracts and reference lists of retrieved articles were reviewed for additional articles, and historical content analyses of grey literature and websites were additionally conducted. Results and discussion Treatment literacy was a well-established concept developed in the global South, which was later partially adopted by international agencies such as the World Health Organization. Treatment literacy emerged as more effective antiretroviral therapies became available. Developed from popular pedagogy and grassroots efforts during an intense struggle for treatment access, treatment literacy addressed the need to extend access to underserved communities and low-income settings that might otherwise be excluded from access. In contrast, prevention literacy is absent in the recent surge of new biomedical prevention strategies; prevention literacy was scarcely referenced and undertheorized in the available literature. Prevention efforts today include multimodal techniques, which jointly comprise a toolkit of biomedical, behavioural, and structural/environmental approaches

    Policy strategies for injury and violence prevention influence systems development, organizational change, social norms, and individual behavior to improve the health and safety of a population. Injury and violence prevention professionals should consider how their issues resonate with various audiences, including policy makers, the public, and other decision makers. As the cost of healthcare continues to rise and greater demands are placed on the healthcare system, the use of public health policy becomes increasingly critical to protect the public's health and prevent injury and violence and its related morbidities and disabilities (Degutis, 2011). This article highlights some impactful policy successes from the field, allows us to reflect on the Injury Center's 20th anniversary, and describes steps to address injuries and violence into the future. The purpose of this paper is to discuss policy as a public health strategy and the critical role it plays in injury and violence prevention.

    This document is a modular self-study guide about criticality safety principles for Idaho National Laboratory emergency responders. This guide provides basic criticality safety information for people who, in response to an emergency, might enter an area that contains much fissionable (or fissile) material. The information should help responders understand unique factors that might be important in responding to a criticality accident or in preventing a criticality accident while responding to a different emergency.

    This study guide specifically supplements web-based training for firefighters (0INL1226) and includes information for other Idaho National Laboratory first responders. However, the guide audience also includes other first responders such as radiological control personnel.

    For interested readers, this guide includes clearly marked additional information that will not be included on tests. The additional information includes historical examples (Been there. Done that.), as well as facts and more in-depth information (Did you know …).

    INL criticality safety personnel revise this guide as needed to reflect program changes, user requests, and better information. Revision 0, issued May 2007, established the basic text. Revision 1 incorporates operation, program, and training changes implemented since 2007. Revision 1 increases focus on first responders because later responders are more likely to have more assistance and guidance from facility personnel and subject matter experts. Revision 1 also completely reorganized the training to better emphasize physical concepts behind the criticality controls that help keep emergency responders safe. The changes are based on and consistent with changes made to course 0INL1226.

    2016-01-01

    The central role of the microbiome in critical illness is supported by a half century of experimental and clinical study. The physiological effects of critical illness and the clinical interventions of intensive care substantially alter the microbiome. In turn, the microbiome predicts patients’ susceptibility to disease, and manipulation of the microbiome has prevented or modulated critical illness in animal models and clinical trials. This Review surveys the microbial ecology of critically ill patients, presents the facts and unanswered questions surrounding gut-derived sepsis, and explores the radically altered ecosystem of the injured alveolus. The revolution in culture-independent microbiology has provided the tools needed to target the microbiome rationally for the prevention and treatment of critical illness, holding great promise to improve the acute and chronic outcomes of the critically ill.

    The ''Disposal Criticality Analysis Methodology Topical Report'' (YMP 2003) presents the methodology for evaluating potential criticality situations in the monitored geologic repository. As stated in the referenced Topical Report, the detailed methodology for performing the disposal criticality analyses will be documented in model reports. Many of the models developed in support of the Topical Report differ from the definition of models as given in the Office of Civilian Radioactive Waste Management procedure AP-SIII.10Q, ''Models'', in that they are procedural, rather than mathematical. These model reports document the detailed methodology necessary to implement the approach presented in the Disposal Criticality Analysis Methodology Topical Report and provide calculations utilizing the methodology. Thus, the governing procedure for this type of report is AP-3.12Q, ''Design Calculations and Analyses''. The ''Criticality Model'' is of this latter type, providing a process evaluating the criticality potential of in-package and external configurations. The purpose of this analysis is to layout the process for calculating the criticality potential for various in-package and external configurations and to calculate lower-bound tolerance limit (LBTL) values and determine range of applicability (ROA) parameters. The LBTL calculations and the ROA determinations are performed using selected benchmark experiments that are applicable to various waste forms and various in-package and external configurations. The waste forms considered in this calculation are pressurized water reactor (PWR), boiling water reactor (BWR), Fast Flux Test Facility (FFTF), Training Research Isotope General Atomic (TRIGA), Enrico Fermi, Shippingport pressurized water reactor, Shippingport light water breeder reactor (LWBR), N-Reactor, Melt and Dilute, and Fort Saint Vrain Reactor spent nuclear fuel (SNF).

    While reflective writing about practice experiences is frequently used in nursing curricula to foster critical thinking, faculty members may be unaware of how to help students reflect, what kinds of feedback are helpful, and how to deal with students' concerns. This article describes faculty best practices in mentoring the student to effectively think critically through structured reflective writing. Models of structured reflection, Baker's four-step model and John's revision of Carper's patterns of knowing, are discussed as effective guides at graduate and undergraduate levels. The article addresses potentially problematic issues with the implementation and evaluation of reflective writing assignments in clinical courses. With foresight and planning, reflective writing may be an empowering strategy for facilitating students' thinking skills.

    Vacuolar protein sorting-35 (VPS35) is essential for endosome-to-Golgi retrieval of membrane proteins. Mutations in the VPS35 gene have been identified in patients with autosomal dominant PD. However, it remains poorly understood if and how VPS35 deficiency or mutation contributes to PD pathogenesis. Here we provide evidence that links VPS35 deficiency to PD-like neuropathology. VPS35 was expressed in mouse dopamine (DA) neurons in substantia nigra pars compacta (SNpc) and STR (striatum)—regions that are PD vulnerable. VPS35-deficient mice exhibited PD-relevant deficits including accumulation of α-synuclein in SNpc-DA neurons, loss of DA transmitter and DA neurons in SNpc and STR, and impairment of locomotor behavior. Further mechanical studies showed that VPS35-deficient DA neurons or DA neurons expressing PD-linked VPS35 mutant (D620N) had impaired endosome-to-Golgi retrieval of lysosome-associated membrane glycoprotein 2a (Lamp2a) and accelerated Lamp2a degradation. Expression of Lamp2a in VPS35-deficient DA neurons reduced α-synuclein, supporting the view for Lamp2a as a receptor of chaperone-mediated autophagy to be critical for α-synuclein degradation. These results suggest that VPS35 deficiency or mutation promotes PD pathogenesis and reveals a crucial pathway, VPS35-Lamp2a-α-synuclein, to prevent PD pathogenesis. SIGNIFICANCE STATEMENT VPS35 is a key component of the retromer complex that is essential for endosome-to-Golgi retrieval of membrane proteins. Mutations in the VPS35 gene have been identified in patients with PD. However, if and how VPS35 deficiency or mutation contributes to PD pathogenesis remains unclear. We demonstrated that VPS35 deficiency or mutation (D620N) in mice leads to α-synuclein accumulation and aggregation in the substantia nigra, accompanied with DA neurodegeneration. VPS35-deficient DA neurons exhibit impaired endosome-to-Golgi retrieval of Lamp2a, which may contribute to the reduced α-synuclein degradation through

    2005-01-01

    Reflection is widely accepted as a learning tool and is considered integral to professional practice. Journal writing is advocated in facilitating reflection, yet little is written about how to assess reflection in journals. The purpose of this study was to develop and test a method of assessing the elements of reflection in journals and to determine whether, and to what level, reflection occurs in journals. Twenty-seven physical therapy students maintained written reflective journals throughout three of their four eight-week clinical affiliations. The students were introduced to concepts of reflective practice with definitions of terms and reflective questions before their second affiliation. A coding schema was developed to assess the journals. Three raters assessed forty-three journals. The text of each journal was analyzed for evidence of nine elements of reflection, and each journal was categorized as showing no evidence of reflection, evidence of reflection, or evidence of critical reflection. Descriptive statistics were used to demonstrate evidence of reflection. Reliability between each pair of raters was assessed using percent agreement, phi coefficients, and gamma statistics. Interrater reliability of all raters was assessed using intraclass correlation coefficients (ICC[2,1]). Results showed that the raters assessed 95.3%-100% of the journals as showing at least one element of reflection. The percent agreement between rater pairs for the nine elements of reflection ranged from 65.1% to 93.0%, the phi coefficient ranged from 0.08 to 0.81, and the ICC(2,1) values used to assess reliability among the three raters on each element ranged from 0.03 to 0.72. Averaging the assessment of the three raters for the overall journal, 14.7% of the journals were assessed as showing no evidence of reflection, 43.4% as showing evidence of reflection, and 41.9% as showing evidence of critical reflection. The percent agreement between rater pairs for the overall assessment

  19. Vulnerability of critical infrastructures : identifying critical nodes.

    Cox, Roger Gary; Robinson, David Gerald

    2004-06-01

    The objective of this research was the development of tools and techniques for the identification of critical nodes within critical infrastructures. These are nodes that, if disrupted through natural events or terrorist action, would cause the most widespread, immediate damage. This research focuses on one particular element of the national infrastructure: the bulk power system. Through the identification of critical elements and the quantification of the consequences of their failure, site-specific vulnerability analyses can be focused at those locations where additional security measures could be effectively implemented. In particular, with appropriate sizing and placement within the grid, distributed generation in the form of regional power parks may reduce or even prevent the impact of widespread network power outages. Even without additional security measures, increased awareness of sensitive power grid locations can provide a basis for more effective national, state and local emergency planning. A number of methods for identifying critical nodes were investigated: small-world (or network theory), polyhedral dynamics, and an artificial intelligence-based search method - particle swarm optimization. PSO was found to be the only viable approach and was applied to a variety of industry accepted test networks to validate the ability of the approach to identify sets of critical nodes. The approach was coded in a software package called Buzzard and integrated with a traditional power flow code. A number of industry accepted test networks were employed to validate the approach. The techniques (and software) are not unique to power grid network, but could be applied to a variety of complex, interacting infrastructures.

  1. Exercise frequency and bone mineral density development in exercising postmenopausal osteopenic women. Is there a critical dose of exercise for affecting bone? Results of the Erlangen Fitness and Osteoporosis Prevention Study.

    2016-08-01

    Due to older people's low sports participation rates, exercise frequency may be the most critical component for designing exercise protocols that address bone. The aims of the present article were to determine the independent effect of exercise frequency (ExFreq) and its corresponding changes on bone mineral density (BMD) and to identify the minimum effective dose that just relevantly affects bone. Based on the 16-year follow-up of the intense, consistently supervised Erlangen Fitness and Osteoporosis Prevention-Study, ExFreq was retrospectively determined in the exercise-group of 55 initially early-postmenopausal females with osteopenia. Linear mixed-effect regression analysis was conducted to determine the independent effect of ExFreq on BMD changes at lumbar spine and total hip. Minimum effective dose of ExFreq based on BMD changes less than the 90% quantile of the sedentary control-group (n=43). Cut-offs were determined after 4, 8, 12 and 16years using bootstrap with 5000 replications. After 16years, average ExFreq ranged between 1.02 and 2.96sessions/week (2.28±0.40sessions/week). ExFreq has an independent effect on LS-BMD (p<.001) and hip-BMD (p=.005) changes. Bootstrap analysis detected a minimum effective dose at about 2sessions/week/16years (cut-off LS-BMD: 2.11, 95% CI: 2.06-2.12; total hip-BMD: 2.22, 95% CI: 2.00-2.78sessions/week/16years). In summary, the minimum effective dose of exercise frequency that relevantly addresses BMD is quite high, at least compared with the low sport participation rate of older adults. This result might not be generalizable across all exercise types, protocols and cohorts, but it does indicate at least that even when applying high impact/high intensity programs, exercise frequency and its maintenance play a key role in bone adaptation.

  4. Reshaping Time: Recommendations for Suicide Prevention in LBGT Populations. Reflections on "Suicide and Suicide Risk in Lesbian, Gay, Bisexual, and Transgender Populations: Review and Recommendations" from Journal of Homosexuality 58(1).

    PubMed

    Mullaney, Clare

    2016-01-01

    This article serves as one of the supplementary pieces of this special issue on "Mapping Queer Bioethics," in which we take a solipsistic turn to "map" the Journal of Homosexuality itself. Here, the author examines the journal's 2011 consensus recommendations for the prevention of LGBT suicide. Invoking the axiom approach of Eve Kosovsky Sedgwick's seminal Epistemology of the Closet, the author argues that merely offering practical guidelines at the level of the demonstrative and the instructive may not be sufficient models to address the urgency of suicide rates in LGBTQ youth populations.

  12. Understanding reflective practice.

    PubMed

    Nicol, Jacqueline Sian; Dosser, Isabel

    2016-05-04

    The Nursing and Midwifery Council (NMC) requires that nurses and midwives use feedback as an opportunity for reflection and learning, to improve practice. The NMC revalidation process stipulates that practitioners provide examples of how they have achieved this. To reflect in a meaningful way, it is important to understand what is meant by reflection, the skills required, and how reflection can be undertaken successfully. Traditionally, reflection occurs after an event encountered in practice. The authors challenge this perception, suggesting that reflection should be undertaken before, during and after an event. This article provides practical guidance to help practitioners use reflective models to write reflective accounts. It also outlines how the reflective process can be used as a valuable learning tool in preparation for revalidation.

    2009-01-01

    When artists depict a mirror in a painting, it necessarily lacks the most obvious property of a mirror: as we move around the painting of the mirror, the reflections we see in it do not change. And yet representations of mirrors and other reflecting surfaces can be quite convincing in paintings. Here, we will examine the rules of reflection, the many ways that painters can break those rules without losing the impression of reflection and the rules that cannot be broken. The rules that govern the perception of reflection are a small subset of the physical rules of reflection. PMID:18534102

  15. Troubling Muddy Waters: Problematizing Reflective Practice in Global Medical Education.

    PubMed

    Naidu, Thirusha; Kumagai, Arno K

    2016-03-01

    The idea of exporting the concept of reflective practice for a global medical education audience is growing. However, the uncritical export and adoption of Western concepts of reflection may be inappropriate in non-Western societies. The emphasis in Western medical education on the use of reflection for a specific end--that is, the improvement of individual clinical practice--tends to ignore the range of reflective practice, concentrating on reflection alone while overlooking critical reflection and reflexivity. This Perspective places the concept of reflective practice under a critical lens to explore a broader view for its application in medical education outside the West. The authors suggest that ideas about reflection in medicine and medical education may not be as easily transferable from Western to non-Western contexts as concepts from biomedical science are. The authors pose the question, When "exporting" Western medical education strategies and principles, how often do Western-trained educators authentically open up to the possibility that there are alternative ways of seeing and knowing that may be valuable in educating Western physicians? One answer lies in the assertion that educators should aspire to turn exportation of educational theory into a truly bidirectional, collaborative exchange in which culturally conscious views of reflective practice contribute to humanistic, equitable patient care. This discussion engages in troubling the already-muddy waters of reflective practice by exploring the global applicability of reflective practice as it is currently applied in medical education. The globalization of medical education demands critical reflection on reflection itself.

  18. [Critical incidents].

    PubMed

    Scheidegger, D

    2005-03-01

    In medicine real severe mishaps are rare. On the other hand critical incidents are frequent. Anonymous critical incident reporting systems allow us to learn from these mishaps. This learning process will make our daily clinical work safer Unfortunately, before these systems can be used efficiently our professional culture has to be changed. Everyone in medicine has to admit that errors do occur to see the need for an open discussion. If we really want to learn from errors, we cannot punish the individual, who reported his or her mistake. The interest is primarily in what has happened and why it has happened and not who has committed this mistake. The cause for critical incidents in medicine is in over 80% the human factor Poor communication, work under enormous stress, conflicts and hierarchies are the main cause. This has been known for many years, therefore have already 15 years ago high-tech industries, like e.g. aviation, started to invest in special courses on team training. Medicine is a typical profession were until now only the individual performance decided about the professional career Communication, conflict management, stress management, decision making, risk management, team and team resource management were subjects that have never been taught during our preor postgraduate education. These points are the most important ones for an optimal teamwork. A multimodular course designed together with Swissair (Human Aspect Development medical, HADmedical) helps to cover, as in aviation, the soft factor and behavioural education in medicine and to prepare professionals in health care to work as a real team.

    Fiscal and financial constraints present a challenge for nurse educators to broaden the diversity and scope of teaching/learning methodologies. One method designed to promote autonomy and self-direction of nursing students is self-reflection combined with reflective journal writing. This paper describes a three-step process of self-reflection encompassing critical appraisal, peer group discussion and self-awareness. This process of self-reflection was initiated with one group of clinical nursing students. Using student and teacher feedback, implications for employing this teaching/learning strategy in clinical practice are suggested.

  1. Lens design with suppressed first order reflections

    NASA Astrophysics Data System (ADS)

    Buchheister, Jan; Weth, Christopher

    2010-08-01

    Optical systems with a reflected light condition, e.g. microscopes with reflected light illumination or fundus cameras, need to have weak first order ghosts or even to be completely free from them. Sequential ray tracing can be used to control optical performance and reflections on a ray basis during optimization. This is significantly more efficient in computation time and convergence than the usual approaches with non-sequential ray tracing or reconfigured optical systems to cover all critical ghosts. An ophthalmic lens for a fundus camera was designed with first order reflections stripped out by applying sequential ray tracing. The merit-function only had to be completed under certain conditions guaranteeing the absence of any reflections. No additional reconfiguration of the optical system in the design software was necessary.

  4. Classifying Intersex in DSM-5: Critical Reflections on Gender Dysphoria.

    PubMed

    Kraus, Cynthia

    2015-07-01

    The new diagnosis of Gender Dysphoria (GD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2013) defines intersex, renamed "Disorders of Sex Development" (DSD), as a specifier of GD. With this formulation, the status of intersex departs from prior editions, especially from the DSM-IV texts that defined intersex as an exclusion criterion for Gender Identity Disorder. Conversely, GD--with or without a DSD--can apply in the same manner to DSD and non-DSD individuals; it subsumes the physical condition under the mental "disorder." This conceptualization, I suggest, is unprecedented in the history of the DSM. In my view, it is the most significant change in the revised diagnosis, and it raises the question of the suitability of psychiatric diagnosis for individuals with intersex/DSD. Unfortunately, this fundamental question was not raised during the revision process. This article examines, historically and conceptually, the different terms provided for intersex/DSD in the DSM in order to capture the significance of the DSD specifier, and the reasons why the risk of stigma and misdiagnosis, I argue, is increased in DSM-5 compared to DSM-IV. The DSM-5 formulation is paradoxically at variance with the clinical literature, with intersex/DSD and transgender being conceived as incommensurable terms in their diagnostic and treatment aspects. In this light, the removal of intersex/DSD from the DSM would seem a better way to achieve the purpose behind the revised diagnosis, which was to reduce stigma and the risk of misdiagnosis, and to provide the persons concerned with healthcare that caters to their specific needs.

  6. [Patient self-determination--reflections on critical and responsible management].

    PubMed

    Eibach, Ulrich

    2003-10-01

    The assumption on which this article is based is that Living Wills represent possible protection against medical and nursing treatments which are detrimental to one's own well-being in the phases of life in which one is no longer or only to a very limited extent capable of making decisions onself. But Living Wills cannot afford protection against grave strokes of fate and safeguard a life of self-determination until death. A Living Will can only constitute a helpful protective function, not only for the sick person but also for all those involved in his/her treatment and care, if it is discussed extensively with others so that these persons can interpret its meaning with respect to medical and nursing treatment in the sense intended by the patient. The article provides indications as to how Living Wills and their handling can best make this protective function possible.

  9. Assimilating sociology: critical reflections on the 'sociology in nursing' debate.

    PubMed

    Mulholland, J

    1997-04-01

    We are witnessing the emergence of a 'new nursing'. In part, this has been associated with the adoption of a 'holistic' model of health and a commitment to a holistic curriculum within nurse education. The role of sociology within the nursing enterprise has been the subject of much debate. This paper seeks to further this debate by arguing that sociology is invaluable to nursing for many reasons but that its value may be undermined as a consequence of being overly constrained within the nursing arena, at the mutual expense of both sociology and the long term interests of nursing itself. This paper will suggest that central to an understanding of how this 'surplus constraint' of sociology occurs in an understanding of the manner in which the holistic model has been adopted in much of nursing and nurse education. The 'indeterminacy' of the holistic model is such that is has empowered a questionable eclecticism, marginalized philosophical controversies within nursing theory, disguised difficult epistemological and ontological conflicts associated with competing claims to truth and facilitated the operation of a form of power whereby sociology has been excluded, at the very moment of its apparent inclusion. This paper goes on to argue that the value of sociology to nursing is dependent upon: firstly, a more systematic and rigorous discussion of its relationship to, and role within, nursing and secondly, a movement away from an implicit 'assimilation' model regarding the incorporation of sociology into nursing towards a more 'multi-cultural' approach. Only under such circumstances may sociology's value to nursing be realized but in a manner that places an importance on maintaining the ontological and epistomological integrity of the sociological tradition.

  12. Critical reflections for understanding the complexity of psychodramatic theory.

    PubMed

    Drakulić, Aleksandra Mindoljević

    2014-03-01

    While being best known as a method of group psychotherapy, classical psychodrama takes on much broader and more complex meanings associated with: theory of roles, education, interactive improvisation theatre and many other contextual frameworks. The meta-theoretical context in which psychodrama is analysed in this work is first of all clinical, psychiatric and psychotherapeutic. In the past ninety years the development of psychodrama in the world has been influenced by many social events and sundry psychology movements. In her work the author describes and analyses the theory of psychodrama in the context of a behavioural and psychoanalytic perspective. She illustrates its origin and connects it with the influence of ancient drama and the developmental concept of modern European theatre in the first half of the last century, the magic/religious tradition of Indian tribes, constructivism and postmodernism, and the deterministic chaos theory. All the mentioned theoretical backgrounds have in their different ways co-created and contributed to the flexibility, integrity and universality of the psychodramatic method and are mutually intertwined in both the theoretical and the practical, clinical sense.

  20. Health Systems Governance for health equity: critical reflections.

    PubMed

    Labonté, Ronald

    2010-01-01

    This article addresses several issues pertinent to health systems governance for health equity. It argues the importance of health systems using measures of positive health (well-being), discriminating in favour of historically less advantaged groups and weighing the costs of health care against investments in the social determinants of health. It cautions that the concept of governance could weaken the role of government, with disequalizing effects, while emphasizing the importance of two elements of good governance (transparency and participation) in health systems decision-making. It distinguishes between participation as volunteer labour and participation as exercising political rights, and questions the assumption that decentralization in health systems is necessarily empowering. It then identifies five health system roles to address issues of equity (educator/watchdog, resource broker, community developer, partnership developer and advocate/catalyst) and the implications of these roles for practice. Drawing on preliminary findings of a global research project on comprehensive primary health care, it discusses political aspects of progressive health system reform and the implications of equity-focused health system governance on health workers' roles, noting the importance of health workers claiming their identity as citizens. The article concludes with a commentary on the inherently political nature of health reforms based on equity; the necessary confrontation with power relations politics involves; and the health systems governance challenge of managing competing health discourses of efficiency and results-based financing, on the one hand, and equity and citizen empowerment, on the other.

  1. Plant critical concept

    SciTech Connect

    O`Regan, P.J.

    1995-12-31

    The achievement of operation and maintenance (O&M) cost reductions is a prime concern for plant operators. Initiatives by the nuclear industry to address this concern are under way and/or in development. These efforts include plant reliability studies, reliability-centered maintenance, risk ranking and testing philosophies, performance-based testing philosophies, graded quality assurance, and so forth. This paper presents the results of an effort to develop a methodology that integrates and applies the common data and analysis requirements for a number of risk-based and performance-based initiatives. This initial phase of the effort applied the methodology and its results to two initiatives. These were the procurement function and the preventive maintenance function. This effort integrated multiple programs and functions to identify those components that are truly critical from an integrated plant performance perspective. The paper describes the scope of the effort, the development of a methodology to identify plant critical components, and the application of these results to the maintenance rule compliance, preventive maintenance, and procurement functions at the candidate plant.

    PubMed

    Mosqueda-Díaz, Angélica; Vílchez-Barboza, Vivian; Valenzuela-Suazo, Sandra; Sanhueza-Alvarado, Olivia

    2014-01-01

    This article reflects on the Critical theory, stemming from the most important philosophical concepts and the modifications it has endured over time. Thereafter, we expose the contribution of the Critical theory to Nursing. This emphasizes on the contextual analysis of the phenomena and it is a self-critique to prevent dogmatisms and totalitarianisms. It postulates that in order to establish a truth, we must consider the historical conditions within which said truth emerges. Jürgen Habermas, with his Theory of Communicative Action, reorients the original postulates of the Critical theory, making it more coherent from the social point of view, through the Guiding Interests of Knowledge. Nursing professionals who follow the Critical theory highlight the need to improve the description of the construction of knowledge with an emancipating and liberating purpose, which permits Nursing to provide responses to approach reality through a global and dialectic vision and from a democratic position of knowledge, construct research from the social situational reality that is part of its daily experience; everything that can be unified as a "Philosophy of Nursing Care", which should be incorporated onto the professional formation of the discipline and onto the research area.

  5. Critical care nursing.

    PubMed

    Dracup, K

    1987-01-01

    The research pertaining to the delivery of nursing care in the ICU was reviewed to describe: the impact of the unit structure and organization, including policies and procedures, on patients, nurses, and families; the process of critical care nursing; the outcomes of critical care nursing; some of the ethical issues germane to the care of the critically ill patient. Although these areas of inquiry are quite diverse, a number of similarities can be identified. The most obvious of the similarities was that, with few exceptions, the studies pertaining to delivery of nursing care were performed by researchers from a variety of disciplines other than nursing, including medicine, psychology, public health, and economics. In many instances, such as the studies of patients' stress experiences in ICUs, these efforts enhanced our knowledge of the phenomena and complemented or replicated the efforts of nurse researchers. Unfortunately, in some areas nurse researchers were quite absent, with the result that the studies lacked a nursing perspective. For example, the large body of knowledge related to the effects of critical care on patient outcome reflected medicine's orientation toward cure. While it is important to measure the effect of nursing care in the ICU on patient survival, the effect of nursing efforts on short- and long-term quality of life, functional status, and health maintenance is also critical and remains unknown. Nurse researchers need to build on the data base already acquired about critical care. Even more important, they need to fashion programs of research focused on the concepts central to the discipline of nursing. A second similarity relates to the increasing quality of the reported research over the past decade. In general, early descriptive studies were conducted in a single critical care unit with a small and often biased sample. These gave way to more carefully designed, multicenter studies, although lack of randomization procedures continued to be
