To pilot and evaluate a machine-markable situational judgement test (SJT) designed to select candidates into UK dental foundation training. Single centre pilot study. UK postgraduate deanery in 2010. Seventy-four candidates attending interview for dental foundation training in Oxford and Wessex Deaneries volunteered to complete the situational judgement test. The situational judgement test was developed to assess relevant professional attributes for dentistry (for example, empathy and integrity) in a machine-markable format. Test content was developed by subject matter experts working with experienced psychometricians. Evaluation of psychometric properties of the pilot situational judgement test (for example, reliability, validity and fairness). Scores in the dental foundation training selection process (short-listing and interviews) were used to examine criterion-related validity. Candidates completed an evaluation questionnaire to examine candidate reactions and face validity of the new test. Forty-six candidates were female and 28 male; mean age was 23.5-years-old (range 22-32). Situational judgement test scores were normally distributed and the test showed good internal reliability when corrected for test length (α = 0.74). Situational judgement test scores positively correlated with the management, leadership and professionalism interview (N = 50; r = 0.43, p <0.01) but not with the clinical skills interview, providing initial evidence of criterion-related validity as the situational judgement test is designed to test non-cognitive professional attributes beyond clinical knowledge. Most candidates perceived the situational judgement test as relevant to dentistry, appropriate for their training level, and fair. This initial pilot study suggests that a situational judgement test is an appropriate and innovative method to measure professional attributes (eg empathy and integrity) for selection into foundation training. Further research will explore the long-term predictive validity of the situational judgement test once candidates have entered training.

Clinical scenarios associated with low therapeutic effectiveness (LTE) are especially complex and highly relevant in oncology. The objective was to test a methodological framework for creating consensual clinical recommendations for routine practice. The study was in three phases from Mars 2006 to January 2008: 1) Definition of LTE situations; 2) Preparation by 10 experts of a panel of LTE situations in cancers of breast, lung, head and neck, colon and rectum and brain; and 3) Development of a consensus on each situation and its optimal treatment by gathering agreement and disagreements (two-round Delphi method) from 68 practicing oncologists in Andalusian Community. Three major and three minor criteria were established for an LTE situation, defined when at least one major or two minor criteria were met. The expert group proposed 48 possible LTE clinical scenarios for breast (n = 7), lung (10), brain (11), head and neck (11) and colorectal cancers (9). Sixty-eight oncologists agreed to participate in the study; the response rate was 79% (from 34 medical and 17 radiation oncologists) In the first round (definition), maximum agreement was obtained with the LTE definition of 10 of the 48 scenarios; in the second round (treatment options), maximum agreement was obtained on the treatment of 3 of these 10 scenarios. Oncologists reached low levels of agreement on the definition of an LTE situation and on its treatment recommendations. This study proposes an approach to the improvement of cancer management in situations of high uncertainty.

The detection of adverse drug events (ADEs) is an important aspect of improving patient safety. The iMedication system employs predefined triggers associated with significant events in a patient's clinical data to automatically detect possible ADEs. We defined four clinically relevant conditions: hyperkalemia, hyponatremia, renal failure, and over-anticoagulation. These are some of the most relevant ADEs in internal medical and geriatric wards. For each patient, ADE risk scores for all four situations are calculated, compared against a threshold, and judged to be monitored, or reported. A ward-based cockpit view summarizes the results.

Decision-making (DM) in healthcare can be understood as an interactive process addressing decision makers' reasoning as well as their visible behaviour after the decision is made. Other key elements of DM are ethical aspects and the role as well as the treatment options of the examined professions. Nurses' DM to choose interventions in situations of severe breathlessness is such interactions. They are also ethically relevant regarding the vulnerability of affected patients and possible restrictions or treatment options. The study aims to explore which factors influence nurses' DM to use nursing interventions in situations where patients suffer from severe breathlessness. Qualitative study including nurses in German hospital wards and hospices. A triangulation of different methods of data collection-participant observation and qualitative expert interviews-and analysis merge in a reflexive grounded theory approach which integrates Goffman's framework analysis. It allows an analysis of nurses' self-statements about DM, their behaviour in relevant clinical situations and its influences. Data collection and analysis will be examined simultaneously. Informed consent will be gained from all participants and the institutional stakeholders. Ongoing consent has to be ensured since observations will take place in healthcare institutions and many patients will be highly vulnerable. The study has been evaluated and approved by the Witten/Herdecke University Ethics Committee, Witten, Germany. Results of the study will be published at congresses and in journal papers.

Background Knowledge and understanding of basic biomedical sciences remain essential to medical practice, particularly when faced with the continual advancement of diagnostic and therapeutic modalities. Evidence suggests, however, that retention tends to atrophy across the span of an average medical course and into the early postgraduate years, as preoccupation with clinical medicine predominates. We postulated that perceived relevance demonstrated through applicability to clinical situations may assist in retention of basic science knowledge. Methods To test this hypothesis in our own medical student cohort, we administered a paper-based 50 MCQ assessment to a sample of students from Years 2 through 5. Covariates pertaining to demographics, prior educational experience, and the perceived clinical relevance of each question were also collected. Results A total of 232 students (Years 2–5, response rate 50%) undertook the assessment task. This sample had comparable demographic and performance characteristics to the whole medical school cohort. In general, discipline-specific and overall scores were better for students in the latter years of the course compared to those in Year 2; male students and domestic students tended to perform better than their respective counterparts in certain disciplines. In the clinical years, perceived clinical relevance was significantly and positively correlated with item performance. Conclusions This study suggests that perceived clinical relevance is a contributing factor to the retention of basic science knowledge and behoves curriculum planners to make clinical relevance a more explicit component of applied science teaching throughout the medical course.

Medical students may not be able to identify the essential elements of situational awareness (SA) necessary for clinical reasoning. Recent studies suggest that students have little insight into cognitive processing and SA in clinical scenarios. Objective Structured Clinical Examinations (OSCEs) could be used to assess certain elements of situational awareness. The purpose of this paper is to review the literature with a view to identifying whether levels of SA based on Endsley's model can be assessed utilising OSCEs during undergraduate medical training. A systematic search was performed pertaining to SA and OSCEs, to identify studies published between January 1975 (first paper describing an OSCE) and February 2017, in peer reviewed international journals published in English. PUBMED, EMBASE, PsycINFO Ovid and SCOPUS were searched for papers that described the assessment of SA using OSCEs among undergraduate medical students. Key search terms included "objective structured clinical examination", "objective structured clinical assessment" or "OSCE" and "non-technical skills", "sense-making", "clinical reasoning", "perception", "comprehension", "projection", "situation awareness", "situational awareness" and "situation assessment". Boolean operators (AND, OR) were used as conjunctions to narrow the search strategy, resulting in the limitation of papers relevant to the research interest. Areas of interest were elements of SA that can be assessed by these examinations. The initial search of the literature retrieved 1127 publications. Upon removal of duplicates and papers relating to nursing, paramedical disciplines, pharmacy and veterinary education by title, abstract or full text, 11 articles were eligible for inclusion as related to the assessment of elements of SA in undergraduate medical students. Review of the literature suggests that whole-task OSCEs enable the evaluation of SA associated with clinical reasoning skills. If they address the levels of SA, these OSCEs can provide supportive feedback and strengthen educational measures associated with higher diagnostic accuracy and reasoning abilities. Based on the findings, the early exposure of medical students to SA is recommended, utilising OSCEs to evaluate and facilitate SA in dynamic environments.

[Leadership Experience of Clinical Nurses: Applying Focus Group Interviews].
Lee, Byoung Sook; Eo, Yong Sook; Lee, Mi Aie
2015-10-01
The purpose of this study was to understand and describe the leadership experience of clinical nurses. During 2014, data were collected using focus group interviews. Three focus group interviews were held with a total of 20 clinical nurses participating. All interviews were recorded as they were spoken and transcribed and data were analyzed using qualitative content analysis. Fifteen categories emerged from the five main themes. 1) Thoughts on the leadership category: to lead others, to cope with problem situations adequately and to serve as a shield against difficulties. 2) Situations requiring leadership: situation that requires correct judgement, coping and situations that need coordination and cooperation. 3-1) Leadership behaviors: other-oriented approach and self-oriented approach. 3-2) Leadership behavior consequences: relevant compensation and unfair termination. 4-1) Facilitators of leadership: confidence and passion for nursing and external support and resources. 4-2) Barriers to leadership: non-supportive organization culture and deficiency in own leadership competencies. 5) Strategies of leadership development: strengthen leadership through self-development and organizational leadership development. In conclusion, the results indicate that it is necessary to enhance clinical nurses' leadership role in healthcare. Enhancement can be achieved through leadership programs focused on enlarging leadership experience, constant self-development, leadership training, and development of leadership competencies suited to the nursing environment.

Dissociative Disorders: Between Neurosis and Psychosis
Devillé, C.; Moeglin, C.; Sentissi, O.
2014-01-01
Dissociative disorders are a set of disorders defined by a disturbance affecting functions that are normally integrated with a prevalence of 2.4 percent in industrialised countries. These disorders are often poorly diagnosed or misdiagnosed because of sharing common clinical features with psychotic disorders, but requiring a very different trajectory of care. Repeated clinical situations in a crisis centre in Geneva provided us with a critical overview of current evidence of knowledge in clinical and etiopathological field about dissociative disorders. Because of their multiple expressions and the overlap with psychotic disorders, we focused on the clinical aspects using three different situations to better understand their specificity and to extend our thinking to the relevance of terms “neurosis” and “psychosis.” Finally, we hope that this work might help physicians and psychiatrists to become more aware of this complex set of disorders while making a diagnosis.

Context Occult hepatitis B (OHB), or persistent HBV DNA in patients who are hepatitis B surface antigen (HBsAg) negative, is a recently recognized entity. In an attempt to summarize the issues, this review presents an overview of the current proposed hypothesis on the clinical relevance and also updates the knowledge on the classification of OHB in different clinical settings. Evidence Acquisition OHB could be found in different population and clinical backgrounds including: viral co-infections (with either human immunodeficiency or hepatitis C viruses), HBV chronic carriers, dialysis patients, transplantation settings and certain clinical situations (named in here: special clinical settings) with no apparent distinguishable clinical parameters. Results The exact magnitude, pathogenesis, and clinical relevance of OHB are unclear. Even the possible role exerted by this cryptic infection on liver disease outcome, and hepatocellular carcinoma development remains unknown. Conclusions Monitoring of Individuals with positive anti-HBc, mass immunization programs and improvement in diagnostic tools seem to be important to control the probability of transmission of HBV through cryptic HBV infection.

Core self-evaluation (CSE) is a personality trait that involves a person’s evaluation of his or her own worth, competence, and capability. The objective of this study was to determine whether medical students’ CSEs exert beneficial effects on their adaptation to their clerkship in terms of their clinical competence and workplace well-being and whether their preclinical academic performance can be a trait-relevant situation that enhances their CSE expression. In total, 127 medical students from 2 cohorts were included as participants in this study. We analyzed complete measures of personal background, objective and subjective preclinical academic performance (course evaluation grades and self-reported efficacy), CSE tendencies, and clinical competence (as objective structured clinical examination scores) and workplace well-being (as compassion satisfaction and burnout) during their 2-year clerkship. Mixed linear models for repeated measures and multiple regressions were employed. Participants’ CSE tendencies had positive effects on their workplace compassion satisfaction and burnout but not on their clinical competence during their clerkship. Additionally, using the objective and subjective preclinical academic performance of the medical students as indicators, we observed that neither could be trait-relevant situations to enhance their CSE expression. CSE personality tendencies might be key to medical students’ ability to noncognitively adapt to clinical training during their clerkships. These tendencies should be identified earlier so that mentors can provide prompt care and support to mentees (medical students) during clerkships. PMID:29186158

This article addresses the rare event of the hostage situation in a forensic psychiatric nursing setting. It has a specific focus on the initial response and the accompanying issues for nurses at the clinical interface as the situation emerges. The intention of this article is to both offer guidance and raise the profile of this unique management issue because little attention is drawn to early-stage hostage situations at an organizational level. When a hostage situation occurs, inadequate preparation can mean the difference between life and death for the hostage, negotiator, or hostage taker. This article provides an overview of the relevant literature and offers guidance about the actions required when a nurse suddenly becomes responsible for managing the early stages of such a traumatic event. Responses, safety, and communication factors concerning the hostage taker are covered.

Clinical governance implementation in a selected teaching emergency department: a systems approach
2012-01-01
Background Clinical governance (CG) is among the different frameworks proposed to improve the quality of healthcare. Iran, like many other countries, has put healthcare quality improvement in its top health policy priorities. In November 2009, implementation of CG became a task for all hospitals across the country. However, it has been a challenge to clarify the notion of CG and the way to implement it in Iran. The purpose of this action research study is to understand how CG can be defined and implemented in a selected teaching emergency department (ED). Methods/design We will use Soft Systems Methodology for both designing the study and inquiring into its content. As we considered a complex problem situation regarding the quality of care in the selected ED, we initially conceptualized CG as a cyclic set of purposeful activities designed to explore the situation and find relevant changes to improve the quality of care. Then, implementation of CG will conceptually be to carry out that set of purposeful activities. The activities will be about: understanding the situation and finding out relevant issues concerning the quality of care; exploring different stakeholders’ views and ideas about the situation and how it can be improved; and defining actions to improve the quality of care through structured debates and development of accommodations among stakeholders. We will flexibly use qualitative methods of data collection and analysis in the course of the study. To ensure the study rigor, we will use different strategies. Discussion Successful implementation of CG, like other quality improvement frameworks, requires special consideration of underlying complexities. We believe that addressing the complex situation and reflections on involvement in this action research will make it possible to understand the concept of CG and its implementation in the selected setting. By describing the context and executed flexible methods of implementation, the results of this study would contribute to the development of implementation science and be employed by boards and executives governing other clinical settings to facilitate CG implementation.

Gatekeepers for Pragmatic Clinical Trials
Whicher, Danielle M.; Miller, Jennifer E.; Dunham, Kelly M.; Joffe, Steven
2015-01-01
To successfully implement a pragmatic clinical trial, investigators need access to numerous resources, including financial support, institutional infrastructure (e.g., clinics, facilities, staff), eligible patients, and patient data. Gatekeepers are people or entities who have the ability to allow or deny access to the resources required to support the conduct of clinical research. Based on this definition, gatekeepers relevant to the United States clinical research enterprise include research sponsors, regulatory agencies, payers, health system and other organizational leadership, research team leadership, human research protections programs, advocacy and community groups, and clinicians. This manuscript provides a framework to help guide gatekeepers’ decision-making related to the use of resources for pragmatic clinical trials. These include (1) concern for the interests of individuals, groups, and communities affected by the gatekeepers’ decisions, including protection from harm and maximization of benefits, (2) advancement of organizational mission and values, and (3) stewardship of financial, human, and other organizational resources. Separate from these ethical considerations, gatekeepers’ actions will be guided by relevant federal, state, and local regulations. This framework also suggests that to further enhance the legitimacy of their decision-making, gatekeepers should adopt transparent processes that engage relevant stakeholders when feasible and appropriate. We apply this framework to the set of gatekeepers responsible for making decisions about resources necessary for pragmatic clinical trials in the United States, describing the relevance of the criteria in different situations and pointing out where conflicts among the criteria and relevant regulations may affect decision-making. Recognition of the complex set of considerations that should inform decision-making will guide gatekeepers in making justifiable choices regarding the use of limited and valuable resources.

To select relevant and feasible instruments for the revision of the Dutch clinical practice guideline for physical therapy in patients with stroke. In this implementation study a comprehensive proposal for ICF categories and matching instruments was developed, based on reliability and validity. Relevant instruments were then selected in a consensus round by 11 knowledge brokers who were responsible for the implementation of the selected instruments. The feasibility of the selected instruments was tested by 36 physical therapists at different work settings within stroke services. Finally, instruments that were deemed relevant and feasible were included in the revised guideline. A total of 28 instruments were recommended for inclusion in the revised guideline. Nineteen instruments were retained from the previous guideline. Ten new instruments were tested in clinical practice, seven of which were found feasible. Two more instruments were added after critical appraisal of the set of the measurement instruments. The revised guideline contains 28 relevant and feasible instrument selected and tested in clinical practice by physical therapists. Further education and implementation is needed to integrate instruments in clinical practice. Further research is proposed for developing and implementing a core set of measurement instruments to be used at fixed time points to establish data registries that allow for continuous improvement of rehabilitation for stroke patients. Implications for Rehabilitation The revised Dutch Stroke Physical Therapy Guideline recommends a total of 28 instruments, that are relevant and feasible for clinical practice of physical therapist in the different settings of stroke rehabilitation. The selection of instrument in daily practice should be part of the clinical reasoning process of PTs and be tailored to individual patients' needs and the degree of priority of the affected ICF category. Suggested education strategies for further integration of instruments in of the daily practice of PTs in Stroke Rehabilitation are: 'Training on the job' and 'peer assessment in clinical situations'.
Dental Cements for Luting and Bonding Restorations: Self-Adhesive Resin Cements.
Manso, Adriana P; Carvalho, Ricardo M
2017-10-01
Self-adhesive resin cements combine easy application of conventional luting materials with improved mechanical properties and bonding capability of resin cements. The presence of functional acidic monomers, dual cure setting mechanism, and fillers capable of neutralizing the initial low pH of the cement are essential elements of the material and should be understood when selecting the ideal luting material for each clinical situation. This article addresses the most relevant aspects of self-adhesive resin cements and their potential impact on clinical performance. Although few clinical studies are available to establish solid clinical evidence, the information presented provides clinical guidance in the dynamic environment of material development.

Recent developments in the field of genomics will impact the daily practice of biology teachers who teach genetics in secondary education. This study reports on the first results of a research project aimed at enhancing biology teacher knowledge for teaching genetics in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of such a situated learning approach. What content knowledge do biology teachers need for teaching genetics in the personal health context of genetic testing? This study describes the required content knowledge by exploring the educational practice and clinical genetic practices. Nine experienced teachers and 12 respondents representing the clinical genetic practices (clients, medical professionals, and medical ethicists) were interviewed about the biological concepts and ethical, legal, and social aspects (ELSA) of testing they considered relevant to empowering students as future health care clients. The ELSA suggested by the respondents were complemented by suggestions found in the literature on genetic counselling. The findings revealed that the required teacher knowledge consists of multiple layers that are embedded in specific genetic test situations: on the one hand, the knowledge of concepts represented by the curricular framework and some additional concepts (e.g. multifactorial and polygenic disorder) and, on the other hand, more knowledge of ELSA and generic characteristics of genetic test practice (uncertainty, complexity, probability, and morality). Suggestions regarding how to translate these characteristics, concepts, and ELSA into context-based genetics education are discussed.

Nurses' clinical decision-making is a complex process that holds potential to influence the quality of care provided and patient outcomes. The evolution of nurses' decision-making that occurs with experience has been well documented. In addition, literature includes numerous strategies and approaches purported to support development of nurses' clinical decision-making. There has been, however, significantly less attention given to the process of assessing nurses' clinical decision-making and novice clinical educators are often challenged with knowing how to best support nurses and nursing students in developing their clinical decision-making capacity. The Situated Clinical Decision-Making framework is presented for use by clinical educators: it provides a structured approach to analyzing nursing students' and novice nurses' decision-making in clinical nursing practice, assists educators in identifying specific issues within nurses' clinical decision-making, and guides selection of relevant strategies to support development of clinical decision-making. A series of questions is offered as a guide for clinical educators when assessing nurses' clinical decision-making. The discussion presents key considerations related to analysis of various decision-making components, including common sources of challenge and errors that may occur within nurses' clinical decision-making. An exemplar illustrates use of the framework and guiding questions. Implications of this approach for selection of strategies that support development of clinical decision-making are highlighted.

Team talk and team activity in simulated medical emergencies: a discourse analytical approach.
Gundrosen, Stine; Andenæs, Ellen; Aadahl, Petter; Thomassen, Gøril
2016-11-14
Communication errors can reduce patient safety, especially in emergency situations that require rapid responses by experts in a number of medical specialties. Talking to each other is crucial for utilizing the collective expertise of the team. Here we explored the functions of "team talk" (talking between team members) with an emphasis on the talk-work relationship in interdisciplinary emergency teams. Five interdisciplinary medical emergency teams were observed and videotaped during in situ simulations at an emergency department at a university hospital in Norway. Team talk and simultaneous actions were transcribed and analysed. We used qualitative discourse analysis to perform structural mapping of the team talk and to analyse the function of online commentaries (real-time observations and assessments of observations based on relevant cues in the clinical situation). Structural mapping revealed recurring and diverse patterns. Team expansion stood out as a critical phase in the teamwork. Online commentaries that occurred during the critical phase served several functions and demonstrated the inextricable interconnections between team talk and actions. Discourse analysis allowed us to capture the dynamics and complexity of team talk during a simulated emergency situation. Even though the team talk did not follow a predefined structure, the team members managed to manoeuvre safely within the complex situation. Our results support that online commentaries contributes to shared team situation awareness. Discourse analysis reveals naturally occurring communication strategies that trigger actions relevant for safe practice and thus provides supplemental insights into what comprises "good" team communication in medical emergencies.
Ambiguity Within Nursing Practice: An Evolutionary Concept Analysis.
McMahon, Michelle A; Dluhy, Nancy M
2017-02-01
To analyze the concept of ambiguity in a nursing context. Ambiguity is inherent within nursing practice. As health care becomes increasingly complex, nurses must continue to successfully deal with greater amounts of clinical ambiguity. Although ambiguity is discussed in nursing, minimal concept refinement exists to capture the contextual intricacies from a nursing lens. Nurse perception of an ambiguous clinical event, in combination with nurse tolerance level for ambiguity, can impact nurse response. Yet, little is known about what constitutes ambiguity within nursing practice (AWNP). Rodgers evolutionary method was used to explore AWNP, with emphasis on nurse thinking during ambiguous clinical situations. Literature searches across multiple databases yielded 38 articles for analysis. Attributes of AWNP include (a) variations in cues/available information, (b) multiple interpretations, (c) novel/nonroutine presentations, and (d) unpredictable. Antecedents include (a) a context-specific, clinical situation with ambiguous features needing evaluation and (b) an individual to sense a knowledge gap or perceive ambiguity. Consequences include ranges of (a) emotional, (b) behavioral, and (c) cognitive clinician responses. Preliminary findings support AWNP as a distinct concept in which ambiguity perceived by the nurse likely affects judgment, decision making, and clinical interventions. AWNP is a clinically relevant concept requiring continued development.

Patients with multiple disorders and on multiple medication are often associated with clinical complexity, defined as a situation of uncertainty conditioned by difficulties in establishing a situational diagnosis and decision-making. The patient-centred care approach in this population group seems to be one of the best therapeutic options. In this context, the preparation of an individualised therapeutic plan is the most relevant practical element, where the pharmacological plan maintains an important role. There has recently been a significant increase in knowledge in the area of adequacy of prescription and adherence. In this context, we must find a model must be found that incorporates this knowledge into clinical practice by the professionals. Person-centred prescription is a medication review model that includes different strategies in a single intervention. It is performed by a multidisciplinary team, and allows them to adapt the pharmacological plan of patients with clinical complexity. Copyright © 2017 SEGG. Publicado por Elsevier España, S.L.U.

Exceptional know how? Possible pitfalls of routinising genetic services.
Schmitz, Dagmar
2010-09-01
Genetic testing practices are increasingly advancing clinical medicine. This process of 'routinisation of genetics' has been conceived as a medical and ethical problem mainly because of the assumption that non-geneticists might lack the necessary skills to provide these services. In particular, the relevant theoretical knowledge in clinical genetics is viewed as insufficient in general practitioners and physicians from other specialities. Empirical findings seem to indicate significant variations not only in theoretical but also in practical knowledge between geneticists and non-geneticists. Several fields of practical knowledge-regarding for example the focus of clinical action, the relevance of therapeutic action or the normative framework-can be identified that are or could be areas of conflict when the routinisation of genetic services proceeds. From an ethical point of view, these variations in know how and background are especially relevant whenever the respective genetic service is concerned with medical information of exceptional normative quality, such as, for example, in prenatal genetic screening and diagnosis of untreatable conditions. Here, the clinically acquired practical knowledge of the non-geneticist could be particularly misleading insofar as there is no relation to therapy and-in a narrow sense-no clinical utility to be assessed. Non-geneticists need a chance to acquire the relevant theoretical and practical knowledge in order to understand and fulfil their own duties in the respective situations in a way that secures the important rights at stake of their patients and clients.
Lung uptake of /sup 99m/Tc--sulfur colloid in falciparum malaria: case report
DOE Office of Scientific and Technical Information (OSTI.GOV)
Ziessman, H.A.
Increased lung uptake of /sup 99m/Tc-sulfur colloid was seen during liver scanning in a patient with falciparum malaria. This finding was due to the enhanced activity of the phagocytic cells of the reticuloendothelial system in the liver, spleen, and lung found in human and experimental malaria. Similar findings in other clinical situations and the relevant literature are reviewed.

Judging applicability (relevance) of meta-analytical findings to particular clinical decision-making situations remains challenging. We aimed to describe an evidence synthesis method that accounts for possible uncertainty regarding applicability of the evidence. We conceptualized uncertainty regarding applicability of the meta-analytical estimates to a decision-making situation as the result of uncertainty regarding applicability of the findings of the trials that were included in the meta-analysis. This trial-level applicability uncertainty can be directly assessed by the decision maker and allows for the definition of trial inclusion probabilities, which can be used to perform a probabilistic meta-analysis with unequal probability resampling of trials (adaptive meta-analysis). A case study with several fictitious decision-making scenarios was performed to demonstrate the method in practice. We present options to elicit trial inclusion probabilities and perform the calculations. The result of an adaptive meta-analysis is a frequency distribution of the estimated parameters from traditional meta-analysis that provides individually tailored information according to the specific needs and uncertainty of the decision maker. The proposed method offers a direct and formalized combination of research evidence with individual clinical expertise and may aid clinicians in specific decision-making situations.

Light distributor for endoscopic photochemotherapy of tumors.
Lenz, P
1987-10-15
This device is fixed to the extremity of an optical fiber and permits light to spread over tumors situated inside hollow organs accessible by endoscopes. Compared to currently used diffusing tips, light distributors have several advantages, in particular precise matching of the irradiated area to the target area, high transmission efficiency, high power density favoring therapeutically relevant hyperthermia, and great mechanical resistance. The clinical usefulness of light distributors has been demonstrated.

The dream is a unique psychodynamically informative instrument for evaluating the subjective correlates of brain activity during REM sleep. These include feelings, percepts, memories, wishes, fantasies, impulses, conflicts, and defenses, as well as images of self and others. Dream analysis can be used in a variety of clinical settings to assist in diagnostic assessment, psychodynamic formulation, evaluation of clinical change, and the management of medically ill patients. Dreams may serve as the initial indicators of transference, resistance, impending crisis, acting-out, conflict resolution, and decision-making. A clinically functional categorization of dreams can facilitate an understanding of psychopathology, psychodynamics, personality structure, and various components of the psychotherapeutic process. Examples of different types of dreams are provided to illustrate their relevance and use in various clinical situations. PMID:11696648
Physicians’ duty to recontact and update genetic advice
Stevens, Yvonne A; Senner, Grant D; Marchant, Gary E
2017-01-01
This perspective addresses whether physicians have a duty to recontact former or current patients to update clinical advice based on newly discovered genomic information. Genetic information is unique compared with other medical data in that the underlying data do not appreciably change during the patients’ lifetime, but the clinical significance of that information will continue to evolve. Based on relevant case law and guidelines, there is no general, established legal duty for physicians to affirmatively recontact former or current patients to update clinical advice based on newly discovered genetic information. However, integration of genomics into clinical practice is advancing quickly, and there may be limited, specific situations where a physician may have a duty to provide updated genetic information.

Pediatric hematologists/oncologists face complex situations such as breaking bad news, treatment/clinical trials discussions, and end-of-life/hospice care. With increasing diversity in patient and physician populations, cultural competency and sensitivity training covering different aspects of pediatric hematology/oncology (PDHO) care can help improve health care delivery and reduce disparities. Though it is considered a required component of fellowship training, there is no clearly defined curriculum meant specifically for PDHO fellows-in-training (PDHO-F). A national online survey of 356 PDHO-F and 67 PDHO program directors (PDHO-PD) was conducted to assess the educational experience, perceptions about identifying barriers including one's own biases and trainee comfort in delivering culturally sensitive care in various PDHO relevant clinical situations. One hundred and eleven (31.2%) PDHO-F and 27 (40.3%) PDHO-PD responded. 30.6% of PDHO-F "strongly agreed/agreed" they received comprehensive cross-cultural communication (CCC) training. The top two teaching methods were faculty role modeling and informal teaching. Majority of CCC training is in medical school or residency and only 10.8% of PDHO-F reported that most of their CCC training was in fellowship. In most clinical situations, there was a modest direct correlation between the fellow's level of agreement that they received comprehensive CCC training and their comfort level. Comfort level with some clinical situations was also significantly different based on year of training. Fellowship training programs should have CCC curricula which use experiential learning models and lay the foundation for promoting cultural awareness, self-reflection, and better patient-physician partnerships which can eventually adapt to and surmount the challenges unique to the physician's chosen field of practice.

This study aimed to investigate the interplay between enduring and situational aging stereotype (AS) effects in older adults' self-reports of clinical and experimentally induced pain. We expected that, as compared with the situational activation of positive AS or a neutral condition, the activation of negative AS would lead to more severe self-reports of clinical pain (H1, hypothesis 1), higher cold pressor task (CPT) pain threshold (H2) and lower CPT pain tolerance (H3), especially among older adults who more strongly endorsed AS. This was a prospective study across two moments in time. At time 1 (T1), 52 older adults (Mage = 74.7; 51.9% women) filled out measures of cultural AS endorsement, clinical pain severity and interference. Three months afterwards (T2), some of these participants collaborated in an experimental study on the effects of AS activation on reported clinical pain (n = 40) and experimentally induced (using CPT) pain threshold and tolerance (n = 35). Our results supported H2, i.e., as compared with the activation of positive AS or a neutral condition, when negative AS were activated older adults showed higher CPT pain thresholds, but this effect was more salient among those who more strongly endorsed AS at T1. This study stresses the influence of cultural AS in older adults' pain experiences showing that the situational activation of negative AS greatly increases experimentally induced pain thresholds of elders who more strongly endorse those stereotypes. It also highlights the relevance of interventions at the level of the physical and/or social environments surrounding elders in pain. © 2014 European Pain Federation - EFIC®

While the overall incidence of emergencies in dermatologic surgery is low, emergent situations can occasionally pose a risk to patients undergoing such procedures. The clinical importance of several types of emergences related to systemic reactions, high energy systems, and trauma are reviewed, and relevant epidemiology, clinical manifestations, diagnosis, work-up, management, and prevention are discussed. Early detection of surgical emergencies can mitigate any associated adverse outcomes, thereby allowing the outstanding record of safety of dermatologic surgery to continue.

[Improvement of team competence in the operating room : Training programs from aviation].
Schmidt, C E; Hardt, F; Möller, J; Malchow, B; Schmidt, K; Bauer, M
2010-08-01
Growing attention has been drawn to patient safety during recent months due to media reports of clinical errors. To date only clinical incident reporting systems have been implemented in acute care hospitals as instruments of risk management. However, these systems only have a limited impact on human factors which account for the majority of all errors in medicine. Crew resource management (CRM) starts here. For the commissioning of a new hospital in Minden, training programs were installed in order to maintain patient safety in a new complex environment. The training was planned in three parts: All relevant processes were defined as standard operating procedures (SOP), visualized and then simulated in the new building. In addition, staff members (trainers) in leading positions were trained in CRM in order to train the complete staff. The training programs were analyzed by questionnaires. Selection of topics, relevance for practice and mode of presentation were rated as very good by 73% of the participants. The staff members ranked the topics communication in crisis situations, individual errors and compensating measures as most important followed by case studies and teamwork. Employees improved in compliance to the SOP, team competence and communication. In high technology environments with escalating workloads and interdisciplinary organization, staff members are confronted with increasing demands in knowledge and skills. To reduce errors under such working conditions relevant processes should be standardized and trained for the emergency situation. Human performance can be supported by well-trained interpersonal skills which are evolved in CRM training. In combination these training programs make a significant contribution to maintaining patient safety.
Serum albumin: accuracy and clinical use.
Infusino, Ilenia; Panteghini, Mauro
2013-04-18
Albumin is the major plasma protein and its determination is used for the prognostic assessment of several diseases. Clinical guidelines call for monitoring of serum albumin with specific target cut-offs that are independent of the assay used. This requires accurate and equivalent results among different commercially available methods (i.e., result standardization) through a consistent definition and application of a reference measurement system. This should be associated with the definition of measurement uncertainty goals based on medical relevance of serum albumin to make results reliable for patient management. In this paper, we show that, in the current situation, if one applies analytical goals for serum albumin measurement derived from its biologic variation, the uncertainty budget derived from each step of the albumin traceability chain is probably too high to fulfil established quality levels for albumin measurement and to guarantee the accuracy needed for clinical usefulness of the test. The situation is further worsened if non-specific colorimetric methods are used for albumin measurement as they represent an additional random source of uncertainty. Copyright © 2013 Elsevier B.V.

PROBLEM ADDRESSED: In addition to clinical instruction, residents need "people" skills that will enable them to deal with all sorts of patients in difficult clinical situations. We planned a series of 12 seminars to teach these skills to first-year residents. OBJECTIVES OF PROGRAM: To ask relevant questions typical of the patient-centred approach; with empathy and respect, to encourage patients to express their emotions; to become more aware of one's own emotions and reactions in one's work as a physician; to negotiate with patients, taking into account both the patient's agenda and one's own. MAIN COMPONENTS OF PROGRAM: Clinical problems drawn from a list of situations likely to involve difficult contact with patients were used to achieve program objectives. Various teaching methods (discussion, brief presentation, practical demonstration, role play) were used during the four stages of skills development: information, demonstration, practice, and feedback. Various tools were used to test the program. CONCLUSION: Proper planning requires ongoing exploration of objectives, content, teaching methods, and evaluation. This discussion of the teaching principles applied in planning our seminars might inspire others to develop similar programs. PMID:10349069
Specific phobias in older adults: characteristics and differential diagnosis.
Coelho, Carlos M; Gonçalves, Daniela C; Purkis, Helena; Pocinho, Margarida; Pachana, Nancy A; Byrne, Gerard J
2010-08-01
Differential diagnosis implies identifying shared and divergent characteristics between clinical states. Clinical work with older adults demands not only the knowledge of nosological features associated with differential diagnosis, but also recognition of idiosyncratic factors associated with this population. Several factors can interfere with an accurate diagnosis of specific phobia in older cohorts. The goal of this paper is to review criteria for specific phobia and its differential diagnosis with panic disorder, agoraphobia, post-traumatic stress disorder and obsessive compulsive disorder, while stressing the specific factors associated with aging. A literature search regarding specific phobia in older adults was carried out using PubMed. Relevant articles were selected and scanned for further pertinent references. In addition, relevant references related to differential diagnosis and assessment were used. Etiologic factors, specificity of feared stimulus or situation, fear predictability and the nature of phobic situations are key points to be assessed when implementing a differential diagnosis of specific phobia. First, age-related sensory impairments are common and interfere both with information processing and communication. Second, medical illnesses create symptoms that might cause, interfere with, or mimic anxiety. Third, cohort effects might result in underreporting, through the inability to communicate or recognize anxiety symptoms, misattributing them to physical conditions. Finally, diagnostic criteria and screening instruments were usually developed using younger samples and are therefore not adapted to the functional and behavioral characteristics of older samples.
Exploring ethics in practice: creating moral community in healthcare one place at a time.
Scott, Sandra L; Marck, Patricia; Barton, Sylvia
2011-01-01
Examining everyday ethical situations in clinical practice is a vital but often overlooked activity for nursing leaders and practitioners, as well as most other healthcare professionals. In this paper, we share how a series of practitioner-led Ethics in Practice sessions (EIPs), which originated within a busy urban teaching hospital, were adapted and translated, first into home care and more recently, into an EIP session for public health nurses. The success of EIP sessions rests with their focus on issues that are selected by practitioners. The aims of EIPs are to foster ethical leadership within communities of practice, create safe places to share concerns, use relevant research evidence and other literature to support informed discussion, and generate stories that deepen our understanding of the ethical situations we encounter in our work. We hope our experience inspires nursing leaders, nursing colleagues and fellow healthcare professionals to consider using the EIP approach to build moral community and the idea of moral imagination with their clinical colleagues, one place at a time.

Basic science in a predoctoral family practice curriculum.
Davies, T C; Barnett, B L
1978-02-01
A course in applied basic science was designed with topic material organized according to anatomic body regions. Details of the diagnostic method were explained early in the course, and clinical procedures for data gathering and problem analyzing were followed while the significance of basic science knowledge in dealing with clinical situations was described. A collection of 35mm slides constituted the focal point of the course. The authors conducted the course together and an atmosphere of intellectual honesty was developed through open discussion between faculty and students. Student curiosity was respected and rewarded. Summaries of the discussions were prepared retrospectively by the faculty instructors for review gy the students. This experience proved that family physicians can demonstrate effectively the relevance of basic science to clinical medicine.
Learning in clinical practice: Stimulating and discouraging response to social comparison.
Raat, Janet; Kuks, Jan; Cohen-Schotanus, Janke
2010-01-01
Social comparison theory is relevant for learning in general. In a clinical context, we examined four hypotheses concerning: preferred other to compare with, preferred direction of comparison, response to social comparison and influence of personal social comparison orientation (SCO). To investigate the relevance of social comparison for clinical workplace learning. Students (n = 437) from nine different hospitals completed two questionnaires measuring their SCO and the direction of and response to their comparisons. t-tests were used to analyse the data. Students substantially did compare. They preferred to compare with peer students more than with residents or staff, and with peers doing better more than with peers doing worse. Their response to social comparison was more often stimulating for learning than discouraging. Students high in SCO reported a stronger stimulating and discouraging response to their comparisons than students low in SCO. Social comparison does play a role in clinical workplace learning. The mainly stimulating response to social comparison indicates a positive learning influence. The preferred comparison with peers emphasizes the role of peers in the learning process. Further research should focus on student comparison behaviour and on situations that strengthen the positive effects of social comparison and reduce the negative or obstructing ones.
Optimizing tooth form with direct posterior composite restorations.
Raghu, Ramya; Srinivasan, Raghu
2011-10-01
Advances in material sciences and technology have provided today's clinicians the strategies to transform the mechanistic approach of operative dentistry into a biologic philosophy. In the last three decades, composite resins have gone from being just an esthetically pleasing way of restoring Class III and Class IV cavities to become the universal material for both anterior and posterior situations as they closely mimic the natural esthetics while restoring the form of the human dentition. In order to enhance their success, clinicians have to rethink their protocol instead of applying the same restorative concepts and principles practiced with metallic restorations. Paralleling the evolution of posterior composite resin materials, cavity designs, restorative techniques and armamentarium have also developed rapidly to successfully employ composite resins in Class II situations. Most of the earlier problems with posterior composites such as poor wear resistance, polymerization shrinkage, postoperative sensitivity, predictable bonding to dentin, etc., have been overcome to a major extent. However, the clinically relevant aspect of achieving tight contacts in Class II situations has challenged clinicians the most. This paper reviews the evolution of techniques and recent developments in achieving predictable contacts with posterior composites. A Medline search was performed for articles on "direct posterior composite contacts." The keywords used were "contacts and contours of posterior composites." The reference list of each article was manually checked for additional articles of relevance.

Situational awareness errors may play an important role in the genesis of patient harm. The authors examined closed anesthesia malpractice claims for death or brain damage to determine the frequency and type of situational awareness errors. Surgical and procedural anesthesia death and brain damage claims in the Anesthesia Closed Claims Project database were analyzed. Situational awareness error was defined as failure to perceive relevant clinical information, failure to comprehend the meaning of available information, or failure to project, anticipate, or plan. Patient and case characteristics, primary damaging events, and anesthesia payments in claims with situational awareness errors were compared to other death and brain damage claims from 2002 to 2013. Anesthesiologist situational awareness errors contributed to death or brain damage in 198 of 266 claims (74%). Respiratory system damaging events were more common in claims with situational awareness errors (56%) than other claims (21%, P < 0.001). The most common specific respiratory events in error claims were inadequate oxygenation or ventilation (24%), difficult intubation (11%), and aspiration (10%). Payments were made in 85% of situational awareness error claims compared to 46% in other claims (P = 0.001), with no significant difference in payment size. Among 198 claims with anesthesia situational awareness error, perception errors were most common (42%), whereas comprehension errors (29%) and projection errors (29%) were relatively less common. Situational awareness error definitions were operationalized for reliable application to real-world anesthesia cases. Situational awareness errors may have contributed to catastrophic outcomes in three quarters of recent anesthesia malpractice claims.Situational awareness errors resulting in death or brain damage remain prevalent causes of malpractice claims in the 21st century.
Teaching strategies for assessing and managing urinary incontinence in older adults.
Bradway, Christine; Cacchione, Pamela

Urinary incontinence is common and affects many aspects of older adults' lives; therefore, it is essential that nursing faculty include this content in classroom and clinical teaching situations. This article describes innovative strategies for teaching upper-level nursing students (e.g., junior and senior undergraduates) about urinary incontinence in older adults, specifically, the relevant anatomy and physiology of continence and associated pathophysiology of urinary incontinence, risk factors and consequences, definitions and types, and effective nursing assessment and management strategies.

This article describes the core outcome set (COS) for atopic eczema trials. COS describe a minimum set of outcomes to be assessed in a defined situation. COS are required to overcome the current situation of different trials using different endpoints with unclear/insufficient measurement properties resulting in incomparable trials. The global multi-stakeholder Harmonising Outcomes Measures for Eczema initiative developed the Harmonising Outcomes Measures for Eczema roadmap as a generic framework for COS development. Following the establishment of a panel representing all stakeholders, a core set of outcome domains need to be selected based on systematic reviews and consensus methods. Outcome measurement instruments to assess these core domains need to be valid, reliable, and feasible. There is broad global consensus that clinical signs, quality of life, symptoms, and long-term control of flares form the COS for atopic eczema trials. The Eczema Area and Severity Index is recommended to assess clinical signs in atopic eczema trials. Systematic reviews to identify adequate outcome measurement instruments for the other core outcome domains are underway. Clinical signs should be assessed in all atopic eczema trials by at least the Eczema Area and Severity Index. Quality of life, symptoms, and flares should also be assessed in all atopic eczema trials by a valid, reliable, and feasible instrument.

In this article based on a literary study, the form of knowledge named familiarity knowledge is examined. Although rooted in the philosophical tradition of Wittgenstein and Polanyi, the development of familiarity knowledge is tied in with clinical practice and particular patients and contexts while paying attention to the framework factors influencing the setting as a whole as well as with theoretical knowledge relevant to the situation at hand. Palliative care makes a backdrop for some of the discussion. Familiarity knowledge can never be context free and attends to that which is unique in every nurse-patient relationship. Both assertive and familiarity knowledge are needed to care for dying patients in a competent, sensitive, and truly caring manner. Mentors need to help students synthesize assertive knowledge and familiarity knowledge during their clinical studies to enrich both kinds of knowledge and deepen their understanding. Student nurses expertly mentored and tutored while caring for dying patients living at home become, for instance, less apprehensive about facing dying patients than students not so mentored. Nurses need to understand the complexity of nursing care to be able to see the uniqueness of the situation and approach the individual patient on the bases of experience and insight.
Situation Model for Situation-Aware Assistance of Dementia Patients in Outdoor Mobility
Yordanova, Kristina; Koldrack, Philipp; Heine, Christina; Henkel, Ron; Martin, Mike; Teipel, Stefan; Kirste, Thomas
2017-01-01
Background: Dementia impairs spatial orientation and route planning, thus often affecting the patient’s ability to move outdoors and maintain social activities. Situation-aware deliberative assistive technology devices (ATD) can substitute impaired cognitive function in order to maintain one’s level of social activity. To build such a system, one needs domain knowledge about the patient’s situation and needs. We call this collection of knowledge situation model. Objective: To construct a situation model for the outdoor mobility of people with dementia (PwD). The model serves two purposes: 1) as a knowledge base from which to build an ATD describing the mobility of PwD; and 2) as a codebook for the annotation of the recorded behavior. Methods: We perform systematic knowledge elicitation to obtain the relevant knowledge. The OBO Edit tool is used for implementing and validating the situation model. The model is evaluated by using it as a codebook for annotating the behavior of PwD during a mobility study and interrater agreement is computed. In addition, clinical experts perform manual evaluation and curation of the model. Results: The situation model consists of 101 concepts with 11 relation types between them. The results from the annotation showed substantial overlapping between two annotators (Cohen’s kappa of 0.61). Conclusion: The situation model is a first attempt to systematically collect and organize information related to the outdoor mobility of PwD for the purposes of situation-aware assistance. The model is the base for building an ATD able to provide situation-aware assistance and to potentially improve the quality of life of PwD. PMID:29060937
Identifying public health competencies relevant to family medicine.
Harvey, Bart J; Moloughney, Brent W; Iglar, Karl T
2011-10-01
Public health situations faced by family physicians and other primary care practitioners, such as severe acute respiratory syndrome (SARS) and more recently H1N1, have resulted in an increased interest to identify the public health competencies relevant to family medicine. At present there is no agreed-on set of public health competencies delineating the knowledge and skills that family physicians should possess to effectively face diverse public health challenges. Using a multi-staged, iterative process that included a detailed literature review, the authors developed a set of public health competencies relevant to primary care, identifying competencies relevant across four levels, from "post-MD" to "enhanced." Feedback from family medicine and public health educator-practitioners regarding the set of proposed "essential" competencies indicated the need for a more limited, feasible set of "priority" areas to be highlighted during residency training. This focused set of public health competencies has begun to guide relevant components of the University of Toronto's Family Medicine Residency Program curriculum, including academic half-days; clinical experiences, especially identifying "teachable moments" during patient encounters; resident academic projects; and elective public health agency placements. These competencies will also be used to guide the development of a family medicine-public health primer and faculty development sessions to support family medicine faculty facilitating residents to achieve these competencies. Once more fully implemented, an evaluation will be initiated to determine the degree to which these public health competencies are being achieved by family medicine graduates, especially whether they attained the knowledge, skills, and confidence necessary to effectively face diverse public health situations-from common to emergent.

Ownership of mobile phones is on the rise, a trend in uptake that transcends age, region, race, and ethnicity, as well as income. It is precisely the emerging ubiquity of mobile phones that has sparked enthusiasm regarding their capacity to increase the reach and impact of health care, including mental health care. Community-based clinicians charged with transporting evidence-based interventions beyond research and training clinics are in turn, ideally and uniquely situated to capitalize on mobile phone uptake and functionality to bridge the efficacy to effectiveness gap. As such, this article delineates key considerations to guide these frontline clinicians in mobile phone-enhanced clinical practice, including an overview of industry data on the uptake of and evolution in the functionality of mobile phone platforms, conceptual considerations relevant to the integration of mobile phones into practice, representative empirical illustrations of mobile-phone enhanced assessment and treatment, and practical considerations relevant to ensuring the feasibility and sustainability of such an approach.

Generation of small molecules to interfere with regulated necrosis.
Degterev, Alexei; Linkermann, Andreas
2016-06-01
Interference with regulated necrosis for clinical purposes carries broad therapeutic relevance and, if successfully achieved, has a potential to revolutionize everyday clinical routine. Necrosis was interpreted as something that no clinician might ever be able to prevent due to the unregulated nature of this form of cell death. However, given our growing understanding of the existence of regulated forms of necrosis and the roles of key enzymes of these pathways, e.g., kinases, peroxidases, etc., the possibility emerges to identify efficient and selective small molecule inhibitors of pathologic necrosis. Here, we review the published literature on small molecule inhibition of regulated necrosis and provide an outlook on how combination therapy may be most effective in treatment of necrosis-associated clinical situations like stroke, myocardial infarction, sepsis, cancer and solid organ transplantation.

Systemic involvement in autoimmune diseases is often unclear and organ changes are confounding, thus making it difficult to have an early accurate diagnosis. In those situations, both clinical and paraclinical findings might orientate the diagnosis, but only histological or immunohistochemistry changes might be accurate enough. The skin histological changes are relevant and sometimes might have a tremendous role in the accurate diagnosis of autoimmune rheumatic diseases, due to the correlation with the clinical systemic manifestations of the diseases and through the accessibility of biopsy. In the same time, muscle biopsy can provide important support for physicians improving diagnosis and optimizing management of connective tissue diseases.
Short dental implants: an emerging concept in implant treatment.

2014-06-01
Short implants have been advocated as a treatment option in many clinical situations where the use of conventional implants is limited. This review outlines the effectiveness and clinical outcomes of using short implants as a valid treatment option in the rehabilitation of edentulous atrophic alveolar ridges. Initially, an electronic search was performed on the following databases: Medline, PubMed, Embase, Cochrane Database of Systematic Reviews, and DARE using key words from January 1990 until May 2012. An additional hand search was included for the relevant articles in the following journals: International Journal of Oral and Maxillofacial Implants, Clinical Oral Implants Research, Journal of Clinical Periodontology, International Journal of Periodontics, Journal of Periodontology, and Clinical Implant Dentistry and Related Research. Any relevant papers from the journals' references were hand searched. Articles were included if they provided detailed data on implant length, reported survival rates, mentioned measures for implant failure, were in the English language, involved human subjects, and researched implants inserted in healed atrophic ridges with a follow-up period of at least 1 year after implant-prosthesis loading. Short implants demonstrated a high rate of success in the replacement of missing teeth in especially atrophic alveolar ridges. The advanced technology and improvement of the implant surfaces have encouraged the success of short implants to a comparable level to that of standard implants. However, further randomized controlled clinical trials and prospective studies with longer follow-up periods are needed.

The optimal design of phase II studies continues to be the subject of vigorous debate, especially with regards to studies of newer molecularly targeted agents. The observations that many new therapeutics ‘fail’ in definitive phase III studies, coupled with the numbers of new agents to be tested as well as the increasing costs and complexity of clinical trials further emphasizes the critical importance of robust and efficient phase II design. The Clinical Trial Design Task Force(CTD-TF)of the NCI Investigational Drug Steering Committee (IDSC) has published a series of discussion papers on Phase II trial design in Clinical Cancer Research. The IDSC has developed formal recommendations regarding aspects of phase II trial design which are the subject of frequent debate such as endpoints(response vs. progression free survival), randomization(single arm designs vs. randomization), inclusion of biomarkers, biomarker based patient enrichment strategies, and statistical design(e.g. two stage designs vs. multiple-group adaptive designs). While these recommendations in general encourage the use of progression-free survival as the primary endpoint, the use of randomization, the inclusion of biomarkers and the incorporation of newer designs, we acknowledge that objective response as an endpoint, and single arm designs, remain relevant in certain situations. The design of any clinical trial should always be carefully evaluated and justified based on the characteristic specific to the situation. PMID:20215557

The aim of the study was to introduce and evaluate the compliance to documentation of situation, background, assessment, recommendation (SBAR) form. Twenty nurses involved in active bedside care were selected by simple random sampling. Use of SBAR was illustrated thru self-instructional module (SIM). Content validity and reliability were established. The situation, background, assessment, recommendation (SBAR) form was disseminated for use in a clinical setting during shift handover. A retrospective audit was undertaken at 1 st week (A1) and 16 th week (A2), post introduction of SIM. Nurse's opinion about the SBAR form was also captured. Majority of nurses were females (65%) in the age group 21-30 years (80%). There was a significant association ( P = 0.019) between overall audit scores and graduate nurses. Significant improvement ( P = 0.043) seen in overall scores between A1 (mean: 23.20) and A2 (mean: 24.26) and also in "Situation" domain ( P = 0.045) as compared to other domains. There was only a marginal improvement in documentation related to patient's allergies and relevant past history (7%) while identifying comorbidities decreased by 40%. Only 70% of nurses had documented plan of care. Most (76%) of nurses expressed that SBAR form was useful, but 24% nurses felt SBAR documentation was time-consuming. The assessment was easy (53%) to document while recommendation was the difficult (53%) part. SBAR technique has helped nurses to have a focused and easy communication during transition of care during handover. Importance and relevance of capturing information need to be reinforced. An audit to look for reduced number of incidents related to communication failures is essential for long-term evaluation of patient outcomes. Use of standardized SBAR in nursing practice for bedside shift handover will improve communication between nurses and thus ensure patient safety.

This study aimed not only to describe the development and implementation of the module but also to evaluate the nursing students' perceptions. A cross-sectional design including 101 students who were asked to participate and answer a survey. We describe the development of the pedagogic module Students Active Learning via Internet Observations based on situated learning. The findings show that learning about service users' own lived experiences via web-based platforms was instructive according to the students: 81% agreed to a high or very high degree. Another important finding was that 96% of students responded that the module had clinical relevance for nursing work. We argue that learning that engages students with data that are contextually and culturally situated is important for developing competence in caregiving. © 2015 Wiley Periodicals, Inc.
[Clinical trials in developing countries: who should define ethics?].
Béréterbide, F; Hirsch, F
2008-04-01
Many clinical trials have proved much more difficult to implement in developing countries than in the Northern countries if not totally impossible. Should we therefore just observe this situation and approve a "double ethical standard"? Clinical trials in developing countries are also a means for volunteers to have access to medical care, therefore how could the process of informed consent keep its significance? In this context, should the participation in clinical trials be restricted or even stopped? If so, we would thus justify the superiority of an international duty of charity compared with the right of autonomy of these populations. This theoretical analysis cannot be precisely justified. On the contrary, it reveals that while informed consent, international organisations and guidelines have the tendency to play a major role in this debate, local ethics committee are too absent although they represent the more relevant and legitimate discussion partners in this dilemma.

When a diagnostic test confirms clinical suspicion, the indicated treatment can be administered. A problem arises when the diagnostic test does not confirm the initially suspected diagnosis; when the suspicion is grounded in clinically validated predictive rules and is high, the problem is even worse. This situation arises in up to 40% of patients with high suspicion for acute pulmonary embolism, raising the question of whether CT angiography of the pulmonary arteries should be done systematically. This paper reviews the literature about this issue and lays out the best evidence about the relevant recommendations for patients with high clinical suspicion of acute pulmonary embolism and negative findings on CT angiography. It also explains the probabilistic concepts derived from Bayes' theorem that can be useful for ascertaining the most appropriate approach in these patients. Copyright © 2017 SERAM.

BET 1: use of glucagon for oesophageal food bolus impaction.
2015-01-01
A shortcut review was carried out to establish whether intravenous glucagon is a safe and effective treatment for patients with suspected lower oesophageal food bolus impaction. Seven studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that there is no evidence for the effectiveness of glucagon in this situation. Its use may be associated with adverse effects such as vomiting, with the potential risk of oesophageal perforation. Intravenous glucagon should therefore be avoided.

Learning to consult with computers.
Liaw, S T; Marty, J J
2001-07-01
To develop and evaluate a strategy to teach skills and issues associated with computers in the consultation. An overview lecture plus a workshop before and a workshop after practice placements, during the 10-week general practice (GP) term in the 5th year of the University of Melbourne medical course. Pre- and post-intervention study using a mix of qualitative and quantitative methods within a strategic evaluation framework. Self-reported attitudes and skills with clinical applications before, during and after the intervention. Most students had significant general computer experience but little in the medical area. They found the workshops relevant, interesting and easy to follow. The role-play approach facilitated students' learning of relevant communication and consulting skills and an appreciation of issues associated with using the information technology tools in simulated clinical situations to augment and complement their consulting skills. The workshops and exposure to GP systems were associated with an increase in the use of clinical software, more realistic expectations of existing clinical and medical record software and an understanding of the barriers to the use of computers in the consultation. The educational intervention assisted students to develop and express an understanding of the importance of consulting and communication skills in teaching and learning about medical informatics tools, hardware and software design, workplace issues and the impact of clinical computer systems on the consultation and patient care.
Financial capacity in older adults: a growing concern for clinicians.
Gardiner, Paul A; Byrne, Gerard J; Mitchell, Leander K; Pachana, Nancy A
2015-02-02
Older people with cognitive impairment and/or dementia may be particularly vulnerable to diminished financial decision-making capacity. Financial capacity refers to the ability to satisfactorily manage one's financial affairs in a manner consistent with personal self-interest and values. Impairment of financial capacity makes the older individual vulnerable to financial exploitation, may negatively affect their family's financial situation and places strain on relationships within the family. Clinicians are often on the front line of responding to queries regarding decision-making capacity, and clinical evaluation options are often not well understood. Assessment of financial capacity should include formal objective assessment in addition to a clinical interview and gathering contextual data. Development of a flexible, empirically supported and clinically relevant assessment approach that spans all dimensions of financial capacity yet is simple enough to be used by non-specialist clinicians is needed.

In crisis situations, there is an enormous burden of disease and very limited resources. To achieve the best possible health outcomes in these situations and ensure that scarce resources are not wasted, knowledge from health research needs to be translated into practice. We investigated what information from health research was needed by humanitarian aid workers in crisis settings and how it could be best provided. Semistructured interviews were conducted by telephone with 19 humanitarian aid workers from a range of organizations around the world and the results analyzed thematically. Participants identified a clear and currently unmet need for access to high-quality health research to support evidence-based practice in crisis situations. They emphasized that research into delivery of health care was potentially more valuable than research into the effectiveness of particular clinical interventions and highlighted the importance of including contextual information to enable the relevance of the research to be assessed. They suggested that providers of health research information and humanitarian aid organizations work together to develop these resources. ©2011 American Medical Association. All rights reserved.

The current proposal for the DSM-5 definition of social anxiety disorder (SAD) is to replace the DSM-IV generalized subtype specifier with one that specifies fears in performance situations only. Relevant evaluations to support this change in youth samples are sparse. The present study examined rates and correlates of the DSM-IV and proposed DSM-5 specifiers in a sample of treatment-seeking children and adolescents with SAD (N = 204). When applying DSM-IV subtypes, 64.2% of the sample was classified as having a generalized subtype of SAD, with the remaining 35.2% classifying as having a nongeneralized subtype SAD. Youth with generalized SAD, relative to those with nongeneralized SAD, were older, had more clinically severe SAD, showed greater depressive symptoms, and were more likely to have a comorbid depressive disorder. No children in the current sample endorsed discrete fear in performance situations only in the absence of fear in other social situations. The present findings call into question the meaningfulness of the proposed changes in treatment-seeking youth with SAD. © 2013 Wiley Periodicals, Inc.

It is the premise of this paper that the need for medical and basic science instruction in dentistry will increase over time. However, student and faculty appreciation of the relevance and significance of medicine and basic science to clinical dentistry has been elusive, largely due to difficulties linking biomedical science instruction and clinical dental instruction. The scope of traditional procedure based oral surgery instruction can be expanded in an attempt to bridge the medical science-clinical gap. Topics such as health status evaluation, medical risk assessment, and a variety of other biomedical issues can be presented to students in a way which imparts specific dental meaning to basic medical science in real-life clinical situations. Using didactic and chair side instruction in an oral surgery clinical environment, students are confronted with the need to understand these issues and how they relate to the patients they encounter who present for dental care.

Recent studies on the immunosuppressive effects of ultraviolet radiation (UVR) and the related resistance to infections in rodents and humans are presented. The waveband dependency of trans-to-cis isomerisation of urocanic acid in the stratum corneum and the role of DNA damage in UVR-induced erythema and immunosuppression were investigated to further elucidate the underlying mechanisms. Furthermore, human experimental studies on UVR-induced immunomodulation were performed. It appeared that the doses needed to suppress various immune parameters in humans (e.g. NK activity, contact hypersensitivity) were higher than those needed in experiments in rodents. Still, extrapolation of experimental animal data to the human situation showed that UVR may impair the resistance to different systemic infections at relevant outdoor doses. In observational human studies we aimed to substantiate the relevance of UVR for infections in humans. It was shown that sunny season was associated with a slightly retarded but clinically non-relevant antibody response to hepatitis B vaccination. Furthermore, sunny season appeared to be associated with a small decline in the number of CD4+ T-helper cells in a cohort of HIV-infected persons and a higher recurrence of herpes simplex and herpes zoster in a cohort of renal transplant recipients. However, in a study among young children a higher exposure to solar UVR was associated with a lower occurrence of upper respiratory tract symptoms. As disentangling the effects of UVR from other relevant factors is often impossible in observational studies, concise quantitative risk estimations for the human situation cannot be given at present.
Biologics in pediatric psoriasis - efficacy and safety.
Dogra, Sunil; Mahajan, Rahul
2018-01-01
Childhood psoriasis is a special situation that is a management challenge for the treating dermatologist. As is the situation with traditional systemic agents, which are commonly used in managing severe psoriasis in children, the biologics are being increasingly used in the recalcitrant disease despite limited data on long term safety. Areas covered: We performed an extensive literature search to collect evidence-based data on the use of biologics in pediatric psoriasis. The relevant literature published from 2000 to September 2017 was obtained from PubMed, using the MeSH words 'biologics', 'biologic response modifiers' and 'treatment of pediatric/childhood psoriasis'. All clinical trials, randomized double-blind or single-blind controlled trials, open-label studies, retrospective studies, reviews, case reports and letters concerning the use of biologics in pediatric psoriasis were screened. Articles covering the use of biologics in pediatric psoriasis were screened and reference lists in the selected articles were scrutinized to identify other relevant articles that had not been found in the initial search. Articles without relevant information about biologics in general (e.g. its mechanism of action, pharmacokinetics and adverse effects) and its use in psoriasis in particular were excluded. We screened 427 articles and finally selected 41 relevant articles. Expert opinion: The available literature on the use of biologics such as anti-tumor necrosis factor (TNF)-α agents, and anti-IL-12/23 agents like ustekinumab suggests that these are effective and safe in managing severe pediatric psoriasis although there is an urgent need to generate more safety data. Dermatologists must be careful about the potential adverse effects of the biologics before administering them to children with psoriasis. It is likely that with rapidly evolving scenario of biologics in psoriasis, these will prove to be very useful molecules particularly in managing severe and recalcitrant psoriasis in pediatric age group.

Alerting providers to public health situations requires timeliness and context-relevance, both lacking in current systems. Incorporating decision support tools into electronic health records may provide a way to deploy public health alerts to clinicians at the point of care. A timely process for responding to Health Alert Network messages sent by the New York City Department of Health and Mental Hygiene was developed by a network of community health centers. Alerts with order sets and recommended actions were created to notify primary care providers of local disease outbreaks. The process, effect, and lessons learned from alerts for Legionella, toxogenic E coli, and measles outbreaks are described. Electronic alerts have the potential to improve management of diseases during an outbreak, including appropriate laboratory testing, management guidance, and diagnostic assistance as well as to enhance bi-directional data exchange between clinical and public health organizations.

Relevance similarity: an alternative means to monitor information retrieval systems
Dong, Peng; Loh, Marie; Mondry, Adrian
2005-01-01
Background Relevance assessment is a major problem in the evaluation of information retrieval systems. The work presented here introduces a new parameter, "Relevance Similarity", for the measurement of the variation of relevance assessment. In a situation where individual assessment can be compared with a gold standard, this parameter is used to study the effect of such variation on the performance of a medical information retrieval system. In such a setting, Relevance Similarity is the ratio of assessors who rank a given document same as the gold standard over the total number of assessors in the group. Methods The study was carried out on a collection of Critically Appraised Topics (CATs). Twelve volunteers were divided into two groups of people according to their domain knowledge. They assessed the relevance of retrieved topics obtained by querying a meta-search engine with ten keywords related to medical science. Their assessments were compared to the gold standard assessment, and Relevance Similarities were calculated as the ratio of positive concordance with the gold standard for each topic. Results The similarity comparison among groups showed that a higher degree of agreements exists among evaluators with more subject knowledge. The performance of the retrieval system was not significantly different as a result of the variations in relevance assessment in this particular query set. Conclusion In assessment situations where evaluators can be compared to a gold standard, Relevance Similarity provides an alternative evaluation technique to the commonly used kappa scores, which may give paradoxically low scores in highly biased situations such as document repositories containing large quantities of relevant data.

One of the core tenets of the scientist-practitioner model, slightly modified to make it applicable to modern neuropsychology, is that assessment procedures should be developed, applied, and interpreted in a relevant scientific framework. However, over the last 30 years, the general structure of a neuropsychological assessment has changed little, if at all. It has continued to focus mainly on the assessment of cognitive constructs such as intelligence, memory, attention, and perception. During the same time period, cognitive neuroscience has focused on integrative systems, largely controlled by frontal mechanisms, that allow individuals to utilize cognitive functions in an adaptive way, especially in the context of novel situations or when social stimuli are ambiguous. Consequently, the gulf between cognitive neuroscience and the practice of clinical neuropsychology has grown uncomfortably large. This article attempts to review some of the developments in cognitive and affective neuroscience that are relevant to an evaluation of neuropsychological abilities, especially in a medicolegal context, to determine whether conventional neuropsychological methods can be considered fit for purpose.
MO-G-9A-01: Imaging Refresher for Standard of Care Radiation Therapy

2014-06-15
Imaging techniques and technology which were previously the domain of diagnostic medicine are becoming increasingly integrated and utilized in radiation therapy (RT) clinical practice. As such, there are a number of specific imaging topics that are highly applicable to modern radiation therapy physics. As imaging becomes more widely integrated into standard clinical radiation oncology practice, the impetus is on RT physicists to be informed and up-to-date on those imaging modalities relevant to the design and delivery of therapeutic radiation treatments. For example, knowing that, for a given situation, a fluid attenuated inversion recovery (FLAIR) image set is most likely whatmore » the physician would like to import and contour is helpful, but may not be sufficient to providing the best quality of care. Understanding the physics of how that pulse sequence works and why it is used could help assess its utility and determine if it is the optimal sequence for aiding in that specific clinical situation. It is thus important that clinical medical physicists be able to understand and explain the physics behind the imaging techniques used in all aspects of clinical radiation oncology practice. This session will provide the basic physics for a variety of imaging modalities for applications that are highly relevant to radiation oncology practice: computed tomography (CT) (including kV, MV, cone beam CT [CBCT], and 4DCT), positron emission tomography (PET)/CT, magnetic resonance imaging (MRI), and imaging specific to brachytherapy (including ultrasound and some brachytherapy specific topics in MR). For each unique modality, the image formation process will be reviewed, trade-offs between image quality and other factors (e.g. imaging time or radiation dose) will be clarified, and typically used cases for each modality will be introduced. The current and near-future uses of these modalities and techniques in radiation oncology clinical practice will also be discussed. Learning Objectives: To review the basic physical science principles of CT, PET, MR, and ultrasound imaging. To understand how the images are created, and present their specific role in patient management and treatment planning for therapeutic radiation (both external beam and brachytherapy). To discuss when and how each specific imaging modality is currently used in clinical practice, as well as how they may come to be used in the near future.« less

Biomarker research is continuously expanding in the field of clinical proteomics. A combination of different proteomic–based methodologies can be applied depending on the specific clinical context of use. Moreover, current advancements in proteomic analytical platforms are leading to an expansion of biomarker candidates that can be identified. Specifically, mass spectrometric techniques could provide highly valuable tools for biomarker research. Ideally, these advances could provide with biomarkers that are clinically applicable for disease diagnosis and/ or prognosis. Unfortunately, in general the biomarker candidates fail to be implemented in clinical decision making. To improve on this current situation, a well-defined study design has to be established driven by a clear clinical need, while several checkpoints between the different phases of discovery, verification and validation have to be passed in order to increase the probability of establishing valid biomarkers. In this review, we summarize the technical proteomic platforms that are available along the different stages in the biomarker discovery pipeline, exemplified by clinical applications in the field of bladder cancer biomarker research.

The current status and trend of clinical pharmacology in developing countries
2013-01-01
Background Several international forums for promoting clinical pharmacology in developing countries have been held since 1980, and several clinical pharmacology programmes targeting developing countries were instituted such that the status of clinical pharmacology in developing countries is not where it was 50 years ago. Therefore, a survey and an appraisal of the literature on the current status of clinical pharmacology in developing countries were undertaken with a hope that it would enable development of appropriate strategies for further promotion of clinical pharmacology in these countries. Methods First, nine determinants (or enabling factors) for running a successful clinical pharmacology programme were identified, i.e., disease burden, drug situation, economic growth, clinical pharmacology activities, recognition, human capital, government support, international collaboration, and support for traditional/alternative medicines. These factors were then evaluated with regard to their current status in the developing countries that responded to an electronic questionnaire, and their historical perspective, using the literature appraisal. From these, a projected trend was constructed with recommendations on the way forward. Results Clinical pharmacology services, research and teaching in developing countries have improved over the past 50 years with over 90% of countries having the appropriate policies for regulation and rational use of medicines in place. Unfortunately, policy implementation remains a challenge, owing to a worsening disease burden and drug situation, versus fewer clinical pharmacologists and other competing priorities for the national budgets. This has led to a preference for training ‘a physician clinical pharmacologist’ in programmes emphasizing local relevancy and for a shorter time, and the training of other professionals in therapeutics for endemic diseases (task shifting), as the most promising strategies of ensuring rational use of medicines. Conclusion Clinical pharmacology in developing countries is advancing in a different way to that in the developed world and continuing support for these efforts will go a long way in promoting improved health for all.

Clinically assisted hydration and the Liverpool Care Pathway: Catholic ethics and clinical evidence.
Nowarska, Anna
2015-08-01
The Liverpool Care Pathway for the Dying Patient (LCP), a framework introduced for providing comfortable care at the last stage of life, has recently become highly contentious. Among the most serious allegations levelled against it, has been that the LCP may be used as a covert form of euthanasia by withdrawal of clinically assisted hydration (CAH). This concern has been raised, in particular by a number of Catholic medical professionals, who have asserted that the LCP is incompatible with Catholic ethics. This paper examines the key Catholic ethical principles relevant to treatment and care towards the end of life (the sanctity/inviolability of life principle, the distinction between ordinary and extraordinary means). Relevant current clinical evidence regarding CAH in relation to terminal thirst, dehydration, prolongation of life and possible negative impacts on the dying is also scrutinised. It is argued that for some patients at the very end of life it may be permissible and even desirable to withhold or withdraw it. Thus, as administration of CAH may become extraordinary, forgoing it in some situations is fully compatible with Catholic ethics. The article therefore concludes that the stance of the LCP in respect of provision of CAH is fully in alignment with Catholic teaching. Published by the BMJ Publishing Group Limited.

Virtues, ecological momentary assessment/intervention and smartphone technology.
Runyan, Jason D; Steinke, Ellen G
2015-01-01
Virtues, broadly understood as stable and robust dispositions for certain responses across morally relevant situations, have been a growing topic of interest in psychology. A central topic of discussion has been whether studies showing that situations can strongly influence our responses provide evidence against the existence of virtues (as a kind of stable and robust disposition). In this review, we examine reasons for thinking that the prevailing methods for examining situational influences are limited in their ability to test dispositional stability and robustness; or, then, whether virtues exist. We make the case that these limitations can be addressed by aggregating repeated, cross-situational assessments of environmental, psychological and physiological variables within everyday life-a form of assessment often called ecological momentary assessment (EMA, or experience sampling). We, then, examine how advances in smartphone application (app) technology, and their mass adoption, make these mobile devices an unprecedented vehicle for EMA and, thus, the psychological study of virtue. We, additionally, examine how smartphones might be used for virtue development by promoting changes in thought and behavior within daily life; a technique often called ecological momentary intervention (EMI). While EMA/I have become widely employed since the 1980s for the purposes of understanding and promoting change amongst clinical populations, few EMA/I studies have been devoted to understanding or promoting virtues within non-clinical populations. Further, most EMA/I studies have relied on journaling, PDAs, phone calls and/or text messaging systems. We explore how smartphone app technology provides a means of making EMA a more robust psychological method, EMI a more robust way of promoting positive change, and, as a result, opens up new possibilities for studying and promoting virtues.
Anatomy by whole body dissection: a focus group study of students' learning experience.
Burgess, Annette; Ramsey-Stewart, George
2015-01-01
The social construction of knowledge within medical education is essential for learning. Students' interactions within groups and associated learning artifacts can meaningfully impact learning. Situated cognition theory poses that knowledge, thinking, and learning are located in experience. In recent years, there has been a reported decline in time spent on anatomy by whole body dissection (AWBD) within medical programs. However, teaching by surgeons in AWBD provides unique opportunities for students, promoting a deeper engagement in learning. In this study, we apply situated cognition theory as a conceptual framework to explore students' perceptions of their learning experience within the 2014 iteration of an 8-week elective AWBD course. At the end of the course, all students (n=24) were invited to attend one of three focus groups. Framework analysis was used to code and categorize data into themes. In total, 20/24 (83%) students participated in focus groups. Utilizing situated cognition theory as a conceptual framework, we illustrate students' learning experiences within the AWBD course. Students highlighted opportunities to create and reinforce their own knowledge through active participation in authentic dissection tasks; guidance and clinical context provided by surgeons as supervisors; and the provision of an inclusive learning community. Situated cognition theory offers a valuable lens through which to view students' learning experience in the anatomy dissection course. By doing so, the importance of providing clinical relevance to medical teaching is highlighted. Additionally, the value of having surgeons teach AWBD and the experience they share is illustrated. The team learning course design, with varying teaching methods and frequent assessments, prompting student-student and student-teacher interaction, was also beneficial for student learning.
Virtues, ecological momentary assessment/intervention and smartphone technology
Runyan, Jason D.; Steinke, Ellen G.
2015-01-01
Virtues, broadly understood as stable and robust dispositions for certain responses across morally relevant situations, have been a growing topic of interest in psychology. A central topic of discussion has been whether studies showing that situations can strongly influence our responses provide evidence against the existence of virtues (as a kind of stable and robust disposition). In this review, we examine reasons for thinking that the prevailing methods for examining situational influences are limited in their ability to test dispositional stability and robustness; or, then, whether virtues exist. We make the case that these limitations can be addressed by aggregating repeated, cross-situational assessments of environmental, psychological and physiological variables within everyday life—a form of assessment often called ecological momentary assessment (EMA, or experience sampling). We, then, examine how advances in smartphone application (app) technology, and their mass adoption, make these mobile devices an unprecedented vehicle for EMA and, thus, the psychological study of virtue. We, additionally, examine how smartphones might be used for virtue development by promoting changes in thought and behavior within daily life; a technique often called ecological momentary intervention (EMI). While EMA/I have become widely employed since the 1980s for the purposes of understanding and promoting change amongst clinical populations, few EMA/I studies have been devoted to understanding or promoting virtues within non-clinical populations. Further, most EMA/I studies have relied on journaling, PDAs, phone calls and/or text messaging systems. We explore how smartphone app technology provides a means of making EMA a more robust psychological method, EMI a more robust way of promoting positive change, and, as a result, opens up new possibilities for studying and promoting virtues.

Sporting activity is becoming a common practice in patients with diabetes mellitus (DM). This situation requires both a preliminary medical assessment and a wide range of changes in treatment which have scarcely been addressed in medical literature. To prepare a clinical guideline on the medical approach to patients with diabetes who practice sport regularly. An expert panel from the Diabetes Mellitus Working Group of the Spanish Society of Endocrinology and Nutrition (SEEN) reviewed the most relevant literature in each of the sections. Based both on this review and on data from the experience of a number of athletes with DM, a number of recommendations were agreed within each section. Finally, the Working Group and representatives of the SEEN jointly discussed all these recommendations. The guideline provides recommendations ranging from medical assessment before patients with DM start to practice sport to actions during and after physical activity. Recommendations are also given on aspects such as the impact of sport on blood glucose control, training schemes, or special risk situations. Copyright © 2015 SEEN.

Clobetasol propionate for psoriasis: are ointments really more potent?
Warino, Lindsey; Balkrishnan, Rajesh; Feldman, Steven R
2006-06-01
Clobetasol propionate is the most common topical therapy used for psoriasis in the US. Conventional dermatologic wisdom is that ointment preparations provide the highest potency (due to their occlusive nature and moisturizing ability) and are best suited for psoriasis. However, patients often find application of ointment to be messy, raising concerns about both short-term and long-term adherence to treatment. This article reviews the current literature and assesses the relative potency of clobetasol propionate ointment compared to other clobetasol propionate preparations in the treatment of psoriasis. Relevant literature was identified by PubMed and Google searches. We included studies of psoriasis that reported the percentage of subjects that achieved desired efficacy endpoints, as well as studies that reported the subjects' mean change in symptoms from baseline. We excluded studies conducted before 1980 and those that allowed concomitant treatments. Efficacy rates ranged from 17% to 80% for the different vehicles: ointment, solution, foam, cream, lotion, shampoo, and emollient. Clobetasol propionate is a very effective treatment for psoriasis. Ointment preparations have similar efficacy to other preparations in clinical trial situations. In clinical practice, a situation in which patient preferences are more likely to affect compliance, it may be best to choose whichever vehicle patients find preferable.
Laboratory measurement of the anticoagulant activity of the non-vitamin K oral anticoagulants.

Non-vitamin K oral anticoagulants (NOACs) do not require routine laboratory monitoring. However, laboratory measurement may be desirable in special situations and populations. This study's objective was to systematically review and summarize current evidence regarding laboratory measurement of the anticoagulant activity of dabigatran, rivaroxaban, and apixaban. We searched PubMed and Web of Science for studies that reported a relationship between drug levels of dabigatran, rivaroxaban, and apixaban and coagulation assay results. Study quality was evaluated using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2). We identified 17 eligible studies for dabigatran, 15 for rivaroxaban, and 4 for apixaban. For dabigatran, a normal thrombin time excludes clinically relevant drug concentrations. The activated partial thromboplastin time (APTT) and prothrombin time (PT) are less sensitive and may be normal at trough drug levels. The dilute thrombin time (R(2) = 0.92 to 0.99) and ecarin-based assays (R(2) = 0.92 to 1.00) show excellent linearity across on-therapy drug concentrations and may be used for drug quantification. For rivaroxaban and apixaban, anti-Xa activity is linear (R(2) = 0.89 to 1.00) over a wide range of drug levels and may be used for drug quantification. Undetectable anti-Xa activity likely excludes clinically relevant drug concentrations. The PT is less sensitive (especially for apixaban); a normal PT may not exclude clinically relevant levels. The APTT demonstrates insufficient sensitivity and linearity for quantification. Dabigatran, rivaroxaban, and apixaban exhibit variable effects on coagulation assays. Understanding these effects facilitates interpretation of test results in NOAC-treated patients. More information on the relationship between drug levels and clinical outcomes is needed.

Minimally invasive diagnostic procedures such as needle-core biopsy and fine-needle aspiration provide adequate material for molecular analyses. Advances in precision oncology are trending toward the interrogation of limited amounts of genomic material to guide clinical and therapeutic decisions. The aim of this study was to investigate the minimum cellularity needed on cytologic smears for the identification of clinically relevant variants with next-generation sequencing (NGS). Thirty cases of cytologically diagnosed, resection-proven primary lung adenocarcinoma were identified. Nineteen of the 30 cases were known to harbor actionable variants. One Diff-Quik (DQ)-stained slide and 1 Papanicolaou (Pap)-stained slide were selected from each case. Cases were categorized as containing fewer than 100 tumor cells, 100 to 500 tumor cells, or more than 500 tumor cells. NGS was performed on the Ion Torrent platform. NGS was successfully performed on all cell blocks and on 90% of the smears. Paired DQ and Pap smears showed similar cellularity, and cases that differed in cellularity were within 1 category of each other. The cases with more than 100 tumor cells had a 93% success rate; this was significantly different from the situation for cases with fewer than 100 tumor cells, which were successfully sequenced only 67% of the time. Overall, NGS was able to provide clinically relevant information for 83% of DQ smears and for 90% of Pap smears tested. The data show a significantly higher likelihood of successful NGS with cytologic smears with more than 100 tumor cells. There was a trend for a higher NGS success rate with Pap smears versus DQ smears. Cancer Cytopathol 2017;125:398-406. © 2017 American Cancer Society. © 2017 American Cancer Society.

Cognitive impairment is a well-documented feature of schizophrenia and represents a major impediment to the functional recovery of patients. The therapeutic strategies to improve cognition in schizophrenia have either used medications (collectively referred to as 'cognitive-enhancing drugs' in this article) or non-pharmacological training approaches ('cognitive remediation'). Cognitive-enhancing drugs have not as yet been successful and cognitive remediation has shown modest success. Therefore, we may need to explore new therapeutic paradigms to improve cognition in schizophrenia. The optimal approach may require a combination of cognitive-enhancing drugs with cognitive remediation. We review the available data from animal and human studies that provide the conceptual basis, proof-of-concept and illustrations of success of such combination strategies in experimental and clinical paradigms in other conditions. We address the major design issues relevant to the choice of the cognitive-enhancing drugs and cognitive remediation, as well as the timing and the duration of the intervention as will be relevant for schizophrenia. Finally, we address the practical realities of the development and testing of such combined approaches in the real-world clinical situation and conclude that while scientifically attractive, there are several practical difficulties to be overcome for this approach to be clinically feasible.

Outpatient nursing clinic for congenital heart disease patients: Copenhagen Transition Program.
Berg, Selina Kikkenborg; Hertz, Pernille Grarup
2007-01-01
Adolescents with congenital heart disease need support transitioning from childhood to adulthood. To become independent, adolescents need to possess knowledge about the disease and how to handle life with congenital heart disease. Outpatient nursing clinics can address issues relevant for adolescents. Creating an environment in which worries and questions can be discussed better prepares adolescents to meet the struggles of living with congenital heart disease. The Copenhagen Transition Program was established in 2004. This outpatient nursing clinic was established by (1) defining the target group, (2) conducting a literature review, (3) collaborating with interdisciplinary colleagues, (4) scheduling visits to the transition-nursing clinic, (5) arranging clinic visits, (6) charting, and (7) testing and evaluating the clinic. Adolescents with congenital heart disease are invited to a consultation with a specially trained nurse, and it is the patients themselves who decide the content of the consultation. Topics such as knowledge about the disease, endocarditis, acute situations, nutrition, contraception, alcohol/drugs, smoking, physical activity, sleep/rest, and education may be discussed. Parents are asked not to participate.

Today´s relevant educational models emphasize that a great part of learning be situated and reflexive; one of those is the Entrusted Professional Activities model. The study objective was to develop a model that integrates Entrusted Professional Activities with a medical school curriculum. From October 2012 a multidisciplinary group met to develop a model with the specialty of obstetrics and gynecology. From two published models of Entrusted Professional Activities and the curriculum of a school of medicine, blocks, units, and daily clinical practice charts were developed. The thematic content of the curriculum was integrated with the appropriate milestones for undergraduate students and the clinical practice needed to achieve it. We wrote a manual with 37 daily clinical practice charts for students (18 of gynecology and 19 of obstetrics) and 37 for teachers. Each chart content was the daily clinical practice, reflection activities, assessment instruments, and bibliography. It is feasible to combine a model of Entrusted Professional Activities with an undergraduate curriculum, which establishes a continuum with postgraduate education.

To investigate the potency of LC-MS/MS by means of sensitivity and the applicability for cassette dosing in microdose clinical trials. Thirty one top-selling 31 drugs were spiked to human plasma, extracted, and analyzed by LC-MS/MS. The lower limits of quantification for each drug varied from 0.08 to 50 pg/mL, and were lower than one eighth of the assumed maximum plasma concentration at microdose in all drugs except for losartan, indicating the high performance in acquisition of full pharmacokinetic profiles at microdose. We also succeeded in simultaneous analysis of multiple compounds, assuming a situation of cassette dosing in which multiple drug candidates would be administrated simultaneously. Together with the features of LC-MS/MS, such as immediate verification, the utilization of non-radiolabeled drugs and no special facilities, we suppose that LC-MS/MS analysis would be widely applicable in conducting microdose clinical studies.

Whooping cough is a re-emerging infection in the world and Latin America. It was considered relevant to investigate the clinical and epidemiological profile of Bordetella spp. and Bordetella pertussis infection in Córdoba province, Argentina; evaluating, at the same time, the co-infection with virus producing respiratory infections that may be confused with whooping cough. All whooping cough suspected cases were studied by Polimerase Chain Reaction, amplifying the repeated insertion sequence (IS) 481 and the promoter gene encoding pertussis toxin, between 2011 and 2013. The data were obtained from the clinical and epidemiological records. From 2,588 whooping cough suspected cases, 11.59% was infected by Bordetella spp. and 9.16% was confirmed as Bordetella pertussis infection. The rate of infection was 7.22 and 1.84 per 100,000 for 2011 and 2012, respectively. The infection presented a seasonal tendency and it was mainly found on the group of children between 13 and 24 months old. The co-infection with virus producing respiratory infections, were uncommon. Paroxysmal cough, cyanosis and/or vomiting were predictors of the infection for Bordetella pertussis. To deal with the re-emergence of whooping cough is important the knowledge of the regional epidemiological situation. This paper shows the situation of these infections in the regional clinical and epidemiological context, and makes the information available for health decision-making.

MDMA-induced hyperthermia is highly variable, unpredictable, and greatly potentiated by the social and environmental conditions of recreational drug use. Current strategies to treat pathological MDMA-induced hyperthermia in humans are palliative and marginally effective, and there are no specific pharmacological treatments to counteract this potentially life-threatening condition. Here, we tested the efficacy of mixed adrenoceptor blockers carvedilol and labetalol, and the atypical antipsychotic clozapine, in reversing MDMA-induced brain and body hyperthermia. We injected rats with a moderate non-toxic dose of MDMA (9 mg/kg) during social interaction, and we administered potential treatment drugs after the development of robust hyperthermia (>2.5 °C), thus mimicking the clinical situation of acute MDMA intoxication. Brain temperature was our primary focus, but we also simultaneously recorded temperatures from the deep temporal muscle and skin, allowing us to determine the basic physiological mechanisms of the treatment drug action. Carvedilol was modestly effective in attenuating MDMA-induced hyperthermia by moderately inhibiting skin vasoconstriction, and labetalol was ineffective. In contrast, clozapine induced a marked and immediate reversal of MDMA-induced hyperthermia via inhibition of brain metabolic activation and blockade of skin vasoconstriction. Our findings suggest that clozapine, and related centrally acting drugs, might be highly effective for reversing MDMA-induced brain and body hyperthermia in emergency clinical situations, with possible life-saving results.

Accurate and robust genomic prediction of celiac disease using statistical learning.
Abraham, Gad; Tye-Din, Jason A; Bhalala, Oneil G; Kowalczyk, Adam; Zobel, Justin; Inouye, Michael
2014-02-01
Practical application of genomic-based risk stratification to clinical diagnosis is appealing yet performance varies widely depending on the disease and genomic risk score (GRS) method. Celiac disease (CD), a common immune-mediated illness, is strongly genetically determined and requires specific HLA haplotypes. HLA testing can exclude diagnosis but has low specificity, providing little information suitable for clinical risk stratification. Using six European cohorts, we provide a proof-of-concept that statistical learning approaches which simultaneously model all SNPs can generate robust and highly accurate predictive models of CD based on genome-wide SNP profiles. The high predictive capacity replicated both in cross-validation within each cohort (AUC of 0.87-0.89) and in independent replication across cohorts (AUC of 0.86-0.9), despite differences in ethnicity. The models explained 30-35% of disease variance and up to ∼43% of heritability. The GRS's utility was assessed in different clinically relevant settings. Comparable to HLA typing, the GRS can be used to identify individuals without CD with ≥99.6% negative predictive value however, unlike HLA typing, fine-scale stratification of individuals into categories of higher-risk for CD can identify those that would benefit from more invasive and costly definitive testing. The GRS is flexible and its performance can be adapted to the clinical situation by adjusting the threshold cut-off. Despite explaining a minority of disease heritability, our findings indicate a genomic risk score provides clinically relevant information to improve upon current diagnostic pathways for CD and support further studies evaluating the clinical utility of this approach in CD and other complex diseases.
Confidence in memory and other cognitive processes in obsessive-compulsive disorder.
Nedeljkovic, Maja; Kyrios, Michael
2007-12-01
Previous studies have implicated beliefs about one's memory (i.e., meta-memory), in maintaining the symptoms of obsessive-compulsive disorder (OCD), particularly with respect to checking rituals. However, most research has focused on task- or situation-specific perceptions about memory performance. Expanding on this research, we undertook two studies with analogue and clinical cohorts to examine the relationship between general 'trait' beliefs about memory and related processes and OCD symptoms. Trait meta-memory as measured in the current study was conceptualised as a multi-dimensional construct encompassing a range of beliefs about memory and related processes including confidence in one's general memory abilities, decision-making abilities, concentration and attention, as well as perfectionistic standards regarding one's memory. Meta-memory factors were associated with OCD symptoms, predicting OCD symptoms over-and-above mood and other OCD-relevant cognitions. Meta-memory factors were found to be particularly relevant to checking symptoms. Implications for theory and research are discussed.

We developed a training program to introduce managers and informal leaders of healthcare organizations to key concepts of teamwork, safety leadership, and simulation to motivate them to act as leaders to improve safety within their sphere of influence. This report describes the simulation scenario and debriefing that are core elements of that program. Twelve teams of clinician and nonclinician managers were selected from a larger set of volunteers to participate in a 1-day, multielement training program. Two simulation exercises were developed: one for teams of nonclinicians and the other for clinicians or mixed groups. The scenarios represented two different clinical situations, each designed to engage participants in discussions of their safety leadership and teamwork issues immediately after the experience. In the scenarios for nonclinicians, participants conducted an anesthetic induction and then managed an ethical situation. The scenario for clinicians simulated a consulting visit to an emergency room that evolved into a problem-solving challenge. Participants in this scenario had a limited time to prepare advice for hospital leadership on how to improve observed safety and cultural deficiencies. Debriefings after both types of scenarios were conducted using principles of "debriefing with good judgment." We assessed the relevance and impact of the program by analyzing participant reactions to the simulation through transcript data and facilitator observations as well as a postcourse questionnaire. The teams generally reported positive perceptions of the relevance and quality of the simulation with varying types and degrees of impact on their leadership and teamwork behaviors. These kinds of clinical simulation exercises can be used to teach healthcare leaders and managers safety leadership and teamwork skills and behaviors.

Assessing young children's mental health is a crucial and challenging task. The aim of the study was to evaluate the clinical relevance of asking parents, nurses, and young children themselves to identify children's mental health problems by only one or two questions. In regular health check-ups of 4- to 9-year-old children (n = 2682), parents and public health nurses assessed by one question whether the child had any emotional or behavioral difficulties. The child completed a self-evaluation enquiry on his/her emotional well-being. A stratified proportion of the participating parents were invited to a diagnostic interview. Sensitivities were fairly good for the parents' (68%), nurses' (65%), and their combined (79%) one-question screens. Difficulties identified by parents and nurses were major risks (OR 10-14) for any child psychiatric disorders (P < 0.001). The child's self-evaluation was related to 2-fold to 3-fold risks (P < 0.05) for any psychiatric diagnosis, for any emotional diagnosis, and for negative situational factors. The one-question screen for parents and public health nurses together quite adequately identified the young children with mental health problems. The child's self-evaluation provided relevant and complementary information on his/her mental health and especially emotional problems.
[The situation of siblings of mentally ill people].
Schmid, R; Spiessl, H; Cording, C
2005-12-01
The purpose of this article is to provide an overview of the current research regarding the situation of mentally ill persons. The relevant literature was identified by means of a computerized MEDLINE search on the years 1996 - 2004 with the key words "sibling" and "mentally ill"/"chronically ill"/"psychiatric disorder" (631 articles). Also the related articles in the MEDLINE search were viewed. Finally 170 articles of journals and books were included in the review. The situation of siblings of psychiatric ill has manifold aspects, which can be classified into the following categories: Burdens due to the relationship to the ill sibling, burdens because of the relations to the shared parents and other family members, and burdens in the daily life of the siblings due to the illness of his/her sibling. On the other side there are rewards and positive developments in their life because of the illness of the sibling. Personal variables like sex, family size and age at onset of the illness are an influence on the experience of the sibling. The revealed burdens of the affected siblings require necessary answers by political representatives, professionals in and outside a clinic, and the involved families.

This study describes children’s “sensory experiences”, generates parents’ perceptions and explanations of these experiences, and compares these experiences across children with and without autism. Parents of 66 preschoolers (29 typically-developing; 37 with autism) were interviewed using a Critical Incident Technique. Parents described a situation where their child had a “good” sensory experience, a situation where their child had a “bad” sensory experience, and their own perception of how these situations felt to the child. The most common unpleasant experiences for both groups related to sound; the most common pleasant experiences involved touch and movement. Children with autism were reported to have more extreme and/or unusual experiences, and negative food-related experiences than typically-developing peers. Parental explanations for children’s responses focused on qualities of the child, stimulus, and/or context. Many parents had difficulty understanding the concept of sensory experiences. Parents of children with autism were more likely to recognize elements in their children’s experiences as being sensory, and likely to attribute these responses to aspects of autism. Parents’ positive response to the interview itself was an unexpected result with clinical relevance. PMID:19432055
The basic traumatic situation in the analytical relationship.
Hartke, Raul
2005-04-01
The author attempts to develop a concept of psychic trauma which would comply with the nucleus of this Freudian notion, that is, an excess of excitations that cannot be processed by the mental apparatus, but which would also consider the functions and the crucial role of objects in the constitution of the psychism and in traumatic conditions, as well as taking into account the methodological positioning according to which the analytical relationship is the sole possible locus of observation, inference and intervention by the psychoanalyst. He considers as a basic or minimal traumatic psychoanalytical situation that in which a magnitude or quality of emotions exceeds the capacity for containment of the psychoanalytical pair, to the point of generating a period or area of dementalisation in the psyche of one or both of the participants, of requiring analytical work on the matter and promoting a significant positive or negative change in the relationship. Availing himself of Bion's theory about the alpha function and the metapsychological conceptions of Freud and Green concerning psychic representations, he presents two theoretical formulations relating to this traumatic situation, utilising them according to the 'altered focus' model proposed by Bion. He presents three clinical examples to illustrate the concept and the relevant theoretical formulations.

Reimbursement is assessed by the Transparency Commission from the Health Authority (HAS) using a medical benefit (SMR) score that gives access to reimbursement, an "improvement of medical service rendered" (ASMR) that determines the added therapeutic value, and the target population. Assessing cancer drugs for reimbursement raises the same issues as other therapeutic classes, with some key differences. Overall survival (OS) is considered by the Transparency Commission as the endpoint for assessing clinical benefit, and yet it is not an applicable primary endpoint in all types of cancer. Later lines of treatment, particularly during the development process, may make it difficult to interpret OS as the primary endpoint. Therefore, progression-free survival (PFS) for metastatic situations and disease-free survival (DFS) in adjuvant situations are wholly relevant endpoints for decisions on the reimbursement of a new cancer drug. Effect size is assessed using actuarial survival curves of the product versus the comparator, and it is difficult to summarise them into one single parameter. Results are generally interpreted based on median survival, which is fragmented because it only measures one point of the curve. The hazard ratio measures the effect of treatment throughout the duration of survival and is therefore more comprehensive in quantifying clinical benefit. Determining an effect size threshold for granting reimbursement is difficult given the diversity of cancer settings and the level of medical need, which influences assessment of the clinical relevance of the observed difference. Rapid progress in comparators (700 molecules in development) and the identification of predictive factors of efficacy (biomarkers, histology, etc.) during development may lead to different ASMR scores per population, or to the restriction of the target population to a subgroup of the marketing authorisation (MA) population in which the expected effect size is greater. To address these issues, the roundtable recommends the possibility of early scientific opinions by the office of the Transparency Commission in order to discuss comparators and the relevance of responder subgroups. It also recommends the possibility of granting a temporary ASMR, on condition of subsequent confirmation by production of data, when reimbursement appears justified in a subpopulation of the MA for which only subgroup analysis is available. © 2010 Société Française de Pharmacologie et de Thérapeutique.
Ethical issues with informed consent from potential living kidney donors.
Petrini, C
2010-05-01
Living organ donation and participation in clinical research trials have several features in common from an ethical perspective. The primary similarity is risk justification: the risk of harm to living organ donors and clinical research participants is justified by a resulting benefit to one or more other individuals. Some authors hold that organ donation and clinical trial participation are full-fledged duties. Such an implicit likening of the two leads to several considerations regarding informed consent in each situation. Informed consent raises ethical concerns in every medical context, and some of those concerns, such as competence, understanding, autonomy, and free or voluntary choice, are uniquely relevant to living organ donation and clinical trial participation. Most countries regulate informed consent procedures for living organ donation in great detail, and although informed consent procedures for clinical trial participation are somewhat less detailed, their rules are subject to review by ethics committees. It would be constructive for research participation informed consent procedures and living organ donation informed consent procedures to learn from one another. Copyright (c) 2009 Elsevier Inc.

Facial emotion processing in pediatric social anxiety disorder: Relevance of situational context.
Schwab, Daniela; Schienle, Anne
2017-08-01
Social anxiety disorder (SAD) typically begins in childhood. Previous research has demonstrated that adult patients respond with elevated late positivity (LP) to negative facial expressions. In the present study on pediatric SAD, we investigated responses to negative facial expressions and the role of social context information. Fifteen children with SAD and 15 non-anxious controls were first presented with images of negative facial expressions with masked backgrounds. Following this, the complete images which included context information, were shown. The negative expressions were either a result of an emotion-relevant (e.g., social exclusion) or emotion-irrelevant elicitor (e.g., weight lifting). Relative to controls, the clinical group showed elevated parietal LP during face processing with and without context information. Both groups differed in their frontal LP depending on the type of context. In SAD patients, frontal LP was lower in emotion-relevant than emotion-irrelevant contexts. We conclude that SAD patients direct more automatic attention towards negative facial expressions (parietal effect) and are less capable in integrating affective context information (frontal effect).

Autonomy-connectedness is the capacity for being on one's own as well as for satisfactorily engaging in interpersonal relationships. Associations have been shown between autonomy-connectedness components (self-awareness, sensitivity to others, and the capacity for managing new situations) and various indices of psychopathology. Both in a theoretical sense as well as for enhancing treatment and prevention, it is relevant to identify which factors most powerfully predict individual differences in autonomy-connectedness: body awareness, alexithymia, or assertiveness. The present study examined this question in a clinical sample of women who were diagnosed as having autonomy problems (N=52) and in a female nonclinical community sample (N=59). In line with expectations, assertiveness was a strong predictor of (all three components of) autonomy-connectedness, as was emotionalizing, one of the alexithymia-components, but the latter in an opposite direction than we had expected: the higher an individual's ability to emotionalize was, the less self-aware and capable to manage new situations that person was, and the more sensitive to others. Cognitive alexithymia contributed to self-awareness as well as to the capacity for managing new situations, and one of the components of body awareness appeared to predict capacity for managing new situations. Our results indicate that assertiveness training and the enhancement of emotion regulation are important elements of autonomy-connectedness targeted interventions. (c) 2008 Wiley Periodicals, Inc.

A Model of Auditory-Cognitive Processing and Relevance to Clinical Applicability.
Edwards, Brent
2016-01-01
Hearing loss and cognitive function interact in both a bottom-up and top-down relationship. Listening effort is tied to these interactions, and models have been developed to explain their relationship. The Ease of Language Understanding model in particular has gained considerable attention in its explanation of the effect of signal distortion on speech understanding. Signal distortion can also affect auditory scene analysis ability, however, resulting in a distorted auditory scene that can affect cognitive function, listening effort, and the allocation of cognitive resources. These effects are explained through an addition to the Ease of Language Understanding model. This model can be generalized to apply to all sounds, not only speech, representing the increased effort required for auditory environmental awareness and other nonspeech auditory tasks. While the authors have measures of speech understanding and cognitive load to quantify these interactions, they are lacking measures of the effect of hearing aid technology on auditory scene analysis ability and how effort and attention varies with the quality of an auditory scene. Additionally, the clinical relevance of hearing aid technology on cognitive function and the application of cognitive measures in hearing aid fittings will be limited until effectiveness is demonstrated in real-world situations.

The Mexican Institute of Social Security (IMSS) considers the relevance of ethics in a similar context than other countries have developed. According to these considerations, IMSS implemented formally of system of local committees on clinical ethics (CLEC), not only to provide support when ethical dilemmas emerge, but to facilitate the development of an ethics culture among health professionals. The implementation of the CLEC network started in 2004, and since then, its number has increased across the country. Currently IMSS has 78 CLECs. Their number continues to grow due to the level of awareness about the importance of ethics for making medical decisions. In November 2006 the first CLEC national meeting was held and the need to redefine strategies to improve performance of CLECS emerged. This article reports the current situation of the CLECs in Mexico.
The role of wildlife (wild birds) in the global transmission of antimicrobial resistance genes
Wang, Jing; Ma, Zhen-Bao; Zeng, Zhen-Ling; Yang, Xue-Wen; Huang, Ying; Liu, Jian-Hua

Antimicrobial resistance is an urgent global health challenge in human and veterinary medicine. Wild animals are not directly exposed to clinically relevant antibiotics; however, antibacterial resistance in wild animals has been increasingly reported worldwide in parallel to the situation in human and veterinary medicine. This underlies the complexity of bacterial resistance in wild animals and the possible interspecies transmission between humans, domestic animals, the environment, and wildlife. This review summarizes the current data on expanded-spectrum β-lactamase (ESBL), AmpC β-lactamase, carbapenemase, and colistin resistance genes in Enterobacteriaceae isolates of wildlife origin. The aim of this review is to better understand the important role of wild animals as reservoirs and vectors in the global dissemination of crucial clinical antibacterial resistance. In this regard, continued surveillance is urgently needed worldwide.

Memory strategies help seniors remember information that is essential for the performance of their daily activities and contribute to their independence in the context of declining memory skills. This study aimed to analyze the categories, the diversity, and relevance of memory strategies known by seniors, and to identify individual characteristics that correlated with these variables. The sample consisted of 294 participants aged 60 and over who decided to take part in a cognitive vitality promotion program. An adapted version of the memory situation questionnaire (Troyer, 2001) was administered to identify the memory strategies that seniors would use in five daily life situations. A scoring grid, also adapted from the questionnaire's original version (Troyer, 2001), was used to quantify the relevance of the strategies that were reported by participants. All participants mentioned at least once that they would use a strategy from the physical category of memory strategies. Out of a possible range of 26 strategies, participants answered an average of 6.14 (SD = 1.7) different answers across the five situations. Based on expert consensus, 67.7% of the mentioned memory strategies were relevant. Diversity and relevance were significantly higher when trying to remember appointments, things to bring or phone numbers (p ≤ 0.05). The level of education, cognitive skills, and participation in leisure activities were related to diversity and relevance of reported strategies. Seniors know various and relevant memory strategies to perform daily activities. The advantages of integrating strategies that they already know in cognitive health promotion programs should be considered in further studies.
Towards a virtual health record for mobile home care of elderly citizens.
Koch, Sabine; Hägglund, Maria; Scandurra, Isabella; Moström, Dennis
2004-01-01
Mobile work situations within home care of the elderly require immediate and ubiquitous access to patient-oriented data. The ongoing Swedish research project "Technical support for Mobile CloseCare" focuses on the development and evaluation of work-scenario oriented ICT support for enhanced home care of elderly citizens. The aim of the project is to provide a seamless and consistent information flow between different health care providers and to give intuitive access to information services for the elderly and their relatives. For that purpose, different independent software components are connected through a mobile communication platform. Flexible access to prioritized information for different users in different work situations will be given through a virtual health record. In order to obtain both usable and clinically relevant results, a user centered system development approach is followed. Evaluation of the project results will be based on usability tests and quasi-experimental studies on how system implementation influences quality of care and job- and life satisfaction for care providers, patients and relatives.

Cardiopulmonary nematodes are life-threatening pet parasites increasingly reported throughout Europe, with overlapping endemic areas. Dirofilaria immitis is a mosquito-borne whilst Angiostrongylus vasorum is a snail-borne pathogen. Both adult nematodes reside in the pulmonary arteries and right cardiac ventricle of domestic and wild canids, causing a wide spectrum of clinical presentations ranging from cough, dyspnoea and exercise intolerance to severe vascular and pulmonary disease with hearth failure that may lead to death. Information about the prevalence and distribution of cardiopulmonary parasites is essential for the control of animal diseases and, in the case of D. immitis, for the control of potentially associated illnesses in humans. However, in Portugal, heartworm studies are limited to few surveys and case reports, possibly underestimating the relevance of these nematodes. The present work reviews the data on cardiopulmonary dirofilariosis and angiostrongylosis in dogs in Portugal, providing a comprehensive update of the epidemiological situation during the past 20 years.

The role of the situation in leadership.
Vroom, Victor H; Jago, Arthur G
2007-01-01
Leadership depends on the situation. Few social scientists would dispute the validity of this statement. But the statement can be interpreted in many different ways, depending, at least in part, on what one means by leadership. This article begins with a definition of leadership and a brief description of 3 historically important theories of leadership. The most recent of these, contingency theories, is argued to be most consistent with existing evidence and most relevant to professional practice. The Vroom, Yetton, and Jago contingency models of participation in decision making are described in depth, and their work provides the basis for identifying 3 distinct ways in which situational or contextual variables are relevant to both research on and the practice of leadership.

Against Strong Ethical Parity: Situated Cognition Theses and Transcranial Brain Stimulation
Heinrichs, Jan-Hendrik
2017-01-01
According to a prominent suggestion in the ethics of transcranial neurostimulation the effects of such devices can be treated as ethically on par with established, pre-neurotechnological alterations of the mind. This parity allegedly is supported by situated cognition theories showing how external devices can be part of a cognitive system. This article will evaluate this suggestion. It will reject the claim, that situated cognition theories support ethical parity. It will however point out another reason, why external carriers or modifications of the mental might come to be considered ethically on par with internal carriers. Section “Why Could There Be Ethical Parity between Neural Tissue and External Tools?” presents the ethical parity theses between external and internal carriers of the mind as well as neurotechnological alterations and established alterations. Section “Extended, Embodied, Embedded: Situated Cognition as a Relational Thesis” will elaborate the different situated cognition approaches and their relevance for ethics. It will evaluate, whether transcranial stimulation technologies are plausible candidates for situated cognition theses. Section “On the Ethical Relevance of Situated Cognition Theses” will discuss criteria for evaluating whether a cognitive tool is deeply embedded with a cognitive system and apply these criteria to transcranial brain stimulation technologies. Finally it will discuss the role diverse versions of situated cognition theory can play in the ethics of altering mental states, especially the ethics of transcranial brain stimulation technologies.

Acinetobacter baumannii constitutes a dreadful problem in many ICUs worldwide. The very limited therapeutic options available for these organisms are a matter of great concern. No specific guidelines exist addressing the prevention and management of A. baumannii infections in the critical care setting. Clinical microbiologists, infectious disease specialists and intensive care physicians were invited by the Chair of the Infection Section of the ESICM to participate in a multidisciplinary expert panel. After the selection of clinically relevant questions, this document provides recommendations about the use of microbiological techniques for identification of A. baumannii in clinical laboratories, antibiotic therapy for severe infections and recommendations to control this pathogen in outbreaks and endemic situations. Evidence supporting each statement was graded according to the European Society of Clinical Microbiology and Infection Diseases (ESCMID) grading system. Empirical coverage of A. baumannii is recommended in severe infections (severe sepsis or septic shock) occurring during an A. baumannii outbreak, in an endemic setting, or in a previously colonized patient. For these cases, a polymyxin is suggested as part of the empirical treatment in cases of a high suspicion of a carbapenem-resistant (CR) A. baumannii strain. An institutional program including staff education, promotion of hand hygiene, strict contact and isolation precautions, environmental cleaning, targeted active surveillance, and antimicrobial stewardship should be instituted and maintained to combat outbreaks and endemic situations. Specific recommendations about prevention and management of A. baumannii infections in the ICU were elaborated by this multidisciplinary panel. The paucity of randomized controlled trials is noteworthy, so these recommendations are mainly based on observational studies and pharmacodynamics modeling.

Developing new clinical practice guidelines (CPGs) can be time-consuming and expensive. A more efficient approach could be to adopt, adapt or contextualise recommendations from existing good quality CPGs so that the resultant guidance is tailored to the local context. The first steps are to search for international CPGs that have a similar purpose, end-users and patients to your situation. The second step is to critically appraise the methodological quality of the CPGs to ensure that your guidance is based on credible evidence. Then the decisions begin. Can you simply 'adopt' this (parent) clinical practice guidelines, and implement the recommendations in their entirety, without any changes, in your setting? If so, then no further work is required. However this situation is rare. What is more likely, is that even if recommendations from the parent clinical practice guidelines can be adopted, how they are implemented needs to address local issues. Thus you may need to 'contextualise' the guidance, by addressing implementation issues such as local workforce, training, health systems, equipment and/or access to services. Generally this means that additional information is required (Practice/Context Points) to support effective implementation of the clinical practice guidelines recommendations. In some cases, you may need to 'adapt' the guidance, where you will make changes to the recommendations so that care is relevant to your local environments. This may involve additional work to search for local research, or obtain local consensus, regarding how best to adapt recommendations. For example, adaptation might reflect substituting one drug for another (drugs have similar effects, but the alternative drug to the recommended one may be cheaper, more easily obtained or more culturally acceptable). There is lack of standardisation of clinical practice guidelines terminology, leading clinical practice guideline activities often being poorly conceptualised or reported. We provide an approach that would help improve efficiency and standardisation of clinical practice guidelines activities.
Athletic Training Clinical Instructors as Situational Leaders.
Meyer, Linda Platt
2002-12-01
OBJECTIVE: To present Situational Leadership as a model that can be implemented by clinical instructors during clinical education. Effective leadership occurs when the leadership style is matched with the observed followers' characteristics. Effective leaders anticipate and assess change and adapt quickly and grow with the change, all while leading followers to do the same. As athletic training students' levels of readiness change, clinical instructors also need to transform their leadership styles and strategies to match the students' ever-changing observed needs in different situations. DATA SOURCES: CINAHL (1982-2002), MEDLINE (1990-2001), SPORT Discus (1949-2002), ERIC (1966-2002), and Internet Web sites were searched. Search terms included leadership, situational leadership, clinical instructors and leadership, teachers as leaders, and clinical education. DATA SYNTHESIS: Situational Leadership is presented as a leadership model to be used by clinical instructors while teaching and supervising athletic training students in the clinical setting. This model can be implemented to improve the clinical-education process. Situational leaders, eg, clinical instructors, must have the flexibility and range of skills to vary their leadership styles to match the challenges that occur while teaching athletic training students. CONCLUSIONS/RECOMMENDATIONS: This leadership style causes the leader to carry a substantial responsibility to lead while giving power away. Communication is one of the most important leadership skills to develop to become an effective leader. It is imperative for the future of the profession that certified athletic trainers continue to develop effective leadership skills to address the changing times in education and expectations of the athletic training profession.
Broadening our understanding of clinical quality: from attribution error to situated cognition.

The tendency to overestimate the influence of personal characteristics on outcomes, and to underestimate the influence of situational factors, is known as the fundamental attribution error. We argue that medical-education researchers and policy makers may be guilty of this error in their quest to understand clinical quality. We suggest that to truly understand clinical quality, they must examine situational factors, which often have a strong influence on the quality of clinical encounters.
Applying evidence-based surgery in daily clinical routine: a feasibility study.

Although the word evidence-based medicine (EBM) has gained wide popularity, only a few studies have evaluated how EBM works in clinical practice. We have prospectively evaluated the feasibility of evidence-based trauma surgery. Orthopaedic trauma surgeons were asked to produce clinical questions related to the treatment of current patients. An informaticist searched the literature (Medline, Cochrane Library, practice guidelines and textbooks) and reported the findings on every following day. The study's main endpoints were the rate of questions for which relevant evidence (>level V) was available and the time necessary to find and critically appraise medical evidence. In total, 44 EBM questions were formulated, mainly concerning treatment options. PubMed was searched for 39 questions, textbooks for 14, the Cochrane Library for 11, online guidelines for 9 and other sources were used for 4 questions. On average, 157 text items (three per questions) were identified as potentially relevant. Journal articles predominated (83%) over textbooks (10%). Sixty-eight percent of the questions (30 of 44) were answered, either on the basis level 1 (n=13 questions), level 2 (n=6), or level 4 evidence (n=14). Trying to answer a question required 53 min on average, split up between 39 min of database searches and 25 min of obtaining full text articles. In four cases, the evidence suggested a change in clinical management. The physicians were very appreciative of our project and found the provided evidence very helpful for their clinical decisions. Time will be the main barrier against the introduction of clinical EBM. It is likely that clinicians reduce EBM to those situations where evidence is likely to be found. Although the impact of EBM on patient-care was limited, the concept of EBM was successfully implemented.
Ethically-based clinical decision-making in physical therapy: process and issues.
Finch, Elspeth; Geddes, E Lynne; Larin, Hélène
2005-01-01
The identification and consideration of relevant ethical issues in clinical decision-making, and the education of health care professionals (HCPs) in these skills are key factors in providing quality health care. This qualitative study explores the way in which physical therapists (PTs) integrate ethical issues into clinical practice decisions and identifies ethical themes used by PTs. A purposive sample of eight PTs was asked to describe a recent ethically-based clinical decision. Transcribed interviews were coded and themes identified related to the following categories: 1) the integration of ethical issues in the clinical decision-making process, 2) patient welfare, 3) professional ethos of the PT, and 4) health care economics and business practices. Participants readily described clinical situations involving ethical issues but rarely identified specific conflicting ethical issues in their description. Ethical dilemmas were more frequently resolved when there were fewer emotional sequelae associated with the dilemma, and the PT had a clear understanding of professional ethos, valued patient autonomy, and explored a variety of alternative actions before implementing one. HCP students need to develop a clear professional ethos and an increased understanding of the economic factors that will present ethical issues in practice.
Research in dental practice: a 'SWOT' analysis.
Burke, F J T; Crisp, R J; McCord, J F
2002-03-01
Most dental treatment, in most countries, is carried out in general dental practice. There is therefore a potential wealth of research material, although clinical evaluations have generally been carried out on hospital-based patients. Many types of research, such as clinical evaluations and assessments of new materials, may be appropriate to dental practice. Principal problems are that dental practices are established to treat patients efficiently and to provide an income for the staff of the practice. Time spent on research therefore cannot be used for patient treatment, so there are cost implications. Critics of practice-based research have commented on the lack of calibration of operative diagnoses and other variables; however, this variability is the stuff of dental practice, the real-world situation. Many of the difficulties in carrying out research in dental practice may be overcome. For the enlightened, it may be possible to turn observations based on the volume of treatment carried out in practice into robust, clinically related and relevant research projects based in the real world of dental practice.
A guide to benzodiazepine selection. Part II: Clinical aspects.
Teboul, E; Chouinard, G
1991-02-01
To suit the specific needs of various clinical situations, selection of an appropriate benzodiazepine derivative should be based on consideration of their different pharmacokinetic and pharmacodynamic properties. Benzodiazepine derivatives that are rapidly eliminated produce the most pronounced rebound and withdrawal syndromes. Benzodiazepines that are slowly absorbed and slowly eliminated are most appropriate for the anxious patient, since these derivatives produce a gradual and sustained anxiolytic effect. Rapidly absorbed and slowly eliminated benzodiazepines are usually more appropriate for patients with sleep disturbances, since the rapid absorption induces sleep and the slower elimination rate may induce less tolerance to the sedative effect. Rational selection of a benzodiazepine for the elderly and for the suspected drug abuser is more problematic. The relevant pharmacokinetic and clinical considerations for these users are discussed. Certain derivatives may possess pharmacodynamic properties not shared by the entire benzodiazepine class; empirical studies have suggested the existence of anti-panic properties for alprazolam and clonazepam, antidepressant properties for alprazolam, and anti-manic properties for clonazepam and possibly lorazepam.

Fractional flow reserve (FFR) measurements can determine the haemodynamic relevance of coronary artery stenoses. Current guidelines recommend their use in lesions in the absence of non-invasive proof of ischaemia. The prognostic impact of FFR has been evaluated in randomised trials, and it has been shown that revascularisation can be safely deferred if FFR is >0.80, while revascularisation of stenoses with FFR values ≤0.80 results in significantly lower event rates compared to medical treatment. Left main stenoses, aorto-ostial lesions, as well as patients with left ventricular hypertrophy and severely-impaired ejection fraction, have been excluded from large, randomised trials. While FFR measurements are relatively straightforward to perform, uncertainty about procedural logistics, as well as data acquisition and interpretation in specific situations, could explain why they are not widely used in clinical practice. We summarise the clinical data in support of FFR measurements, and provide recommendations for performing and interpreting the procedure. PMID:29588737
Cultural competence in the era of evidence-based practice.
Engebretson, Joan; Mahoney, Jane; Carlson, Elizabeth D
2008-01-01
Cultural competence has become an important concern for contemporary health care delivery, with ethical and legal implications. Numerous educational approaches have been developed to orient clinicians, and standards and position statements promoting cultural competence have been published by both the American Medical Association and the American Nurses Association. Although a number of health care regulatory agencies have developed standards or recommendations, clinical application to patient care has been challenging. These challenges include the abstract nature of the concept, essentializing culture to race or ethnicity, and the attempts to associate culture with health disparities. To make cultural competence relevant to clinical practice, we linked a cultural competency continuum that identifies the levels of cultural competency (cultural destructiveness, cultural incapacity, cultural blindness, cultural precompetence, and cultural proficiency) to well-established values in health care. This situates cultural competence and proficiency in alignment with patient-centered care. A model integrating the cultural competency continuum with the components of evidence-based care (i.e., best research practice, clinical expertise, and patient's values and circumstances) is presented.

High quality clinical decision-making (CDM) has been highlighted as a priority across the nursing profession. Triage nurses, in the Accident and Emergency (A&E) department, work in considerable levels of uncertainty and require essential skills including: critical thinking, evaluation and decision-making. The content of this paper aims to promote awareness of how triage nurses make judgements and decisions in emergency situations. By exploring relevant literature on clinical judgement and decision-making theory, this paper demonstrates the importance of high quality decision-making skills underpinning the triage nurse's role. Having an awareness of how judgements and decisions are made is argued as essential, in a time where traditional nurse boundaries and responsibilities are never more challenged. It is hoped that the paper not only raises this awareness in general but also, in particular, engages the triage nurse to look more critically at how they make their own decisions in their everyday practice.

[The diagnostic process in spina bifida: parents perception and viewpoint of clinical specialists].
Herb, G; Streeck, S
1995-01-01
This is a study of the subjective experience of communicative understanding between parents of spina bifida children and medical personnel. Research methods include content analysis of data from semi-structured interviews, a questionnaire to explore the quality of life as well as conversation analytic reconstructions of the "real" communication processes during outpatient clinic which were tape-recorded. Results of the interviews with parents and personnel demonstrate the great relevance of the quality of the relationship in the providing of clinical care; equally important is that the relationship between parents and clinic staff is shaped in a reciprocal fashion. Discrepancies in the perceptions of parents and personnel indicate individual reality constructions. It is desirable that parents and personnel construct a shared reality during their interaction. With respect to this end, the emotional resources of personnel should be regarded as competences and drawn upon more systematically. The parents' role as "experts" should be validated and their active participation in the construction of the communicative situation - which is normally determined by the institution - should be encouraged.
Prospects for a Clinical Science of Mindfulness-Based Intervention
Dimidjian, Sona; Segal, Zindel V.
2017-01-01
Mindfulness-based interventions are at a pivotal point in their future development. Spurred on by an ever-increasing number of studies and breadth of clinical application, the value of such approaches may appear self-evident. We contend, however, that the public health impact of mindfulness-based interventions can be enhanced significantly by situating this work in a broader framework of clinical psychological science. Utilizing the National Institute of Health stage model (Onken, Carroll, Shoham, Cuthbert, & Riddle, 2014), we map the evidence base for mindfulness-based cognitive therapy and mindfulness-based stress reduction as exemplars of mindfulness-based interventions. From this perspective, we suggest that important gaps in the current evidence base become apparent and, furthermore, that generating more of the same types of studies without addressing such gaps will limit the relevance and reach of these interventions. We offer a set of 7 recommendations that promote an integrated approach to core research questions, enhanced methodological quality of individual studies, and increased logical links among stages of clinical translation in order to increase the potential of MBIs to impact positively the mental health needs of individuals and communities.

[Basic concepts for network meta-analysis].
Catalá-López, Ferrán; Tobías, Aurelio; Roqué, Marta
2014-12-01
Systematic reviews and meta-analyses have long been fundamental tools for evidence-based clinical practice. Initially, meta-analyses were proposed as a technique that could improve the accuracy and the statistical power of previous research from individual studies with small sample size. However, one of its main limitations has been the fact of being able to compare no more than two treatments in an analysis, even when the clinical research question necessitates that we compare multiple interventions. Network meta-analysis (NMA) uses novel statistical methods that incorporate information from both direct and indirect treatment comparisons in a network of studies examining the effects of various competing treatments, estimating comparisons between many treatments in a single analysis. Despite its potential limitations, NMA applications in clinical epidemiology can be of great value in situations where there are several treatments that have been compared against a common comparator. Also, NMA can be relevant to a research or clinical question when many treatments must be considered or when there is a mix of both direct and indirect information in the body of evidence.

Clinical pharmacology in Russia has long history and is currently active, but rather unrecognized internationally. It is governmentally approved as a teaching/scientific specialty since 1983 and as a medical specialty since 1997. Courses of clinical pharmacology are included in the undergraduate curricula in the 5th and/or 6th year of education at all medical schools in the Russian Federation. Postgraduate education includes initial specialization in internal medicine with further residency in clinical pharmacology. Governmental legislation recommends that every healthcare institution has either a department or a single position of clinical pharmacologist. Major routine duties include information about and monitoring of medication use, consultations in difficult clinical situations, pharmacogenetic counseling, therapeutic drug monitoring, pharmacovigilance, and participation in drug and therapeutics (formulary) committees. There are official experts in clinical pharmacology in Russia responsible for coordinating relevant legislative issues. The chief expert clinical pharmacologist represents the discipline directly at the Ministry of Health. Research in clinical pharmacology in Russia is extensive and variable, but only some of it is published internationally. Russia is a participant of international societies of clinical pharmacology and therapeutics and collaboration is actively ongoing. There are still certain problems related to the development of the discipline in Russia-some healthcare institutions do not see the need for clinical pharmacology. However, the number of clinical pharmacologists in Russia is increasing as well as their role in physicians' education, national healthcare, and research.

Autonomous vehicles, though having enormous potential, face a number of challenges. As a computer system interacting with society on a large scale and human beings in particular, they will encounter situations, which require moral assessment. What will count as right behavior in such situations depends on which factors are considered to be both morally justified and socially acceptable. In an empirical study we investigated what factors people recognize as relevant in driving situations. The study put subjects in several “dilemma” situations, which were designed to isolate different and potentially relevant factors. Subjects showed a surprisingly high willingness to sacrifice themselves to save others, took the age of potential victims in a crash into consideration and were willing to swerve onto a sidewalk if this saved more lives. The empirical insights are intended to provide a starting point for a discussion, ultimately yielding societal agreement whereby the empirical insights should be balanced with philosophical considerations.

Context: Fatigue and underperformance are common in athletes. Understanding overtraining syndrome (OTS) is helpful in the evaluation, management, and education of athletes. Evidence Acquisition: Relevant articles in English were searched with OVID (1948-2011) and PubMed using the following keywords: overtraining syndrome, overtraining, overreaching, unexplained underperformance, staleness, pathophysiology, management, treatment, evaluation. Bibliographies were reviewed for additional resources. Results: OTS appears to be a maladapted response to excessive exercise without adequate rest, resulting in perturbations of multiple body systems (neurologic, endocrinologic, immunologic) coupled with mood changes. Many hypotheses of OTS pathogenesis are reviewed, and a clinical approach to athletes with possible OTS (including history, testing, and prevention) is presented. Conclusions: OTS remains a clinical diagnosis with arbitrary definitions per the European College of Sports Science’s position statement. History and, in most situations, limited serologies are helpful. However, much remains to be learned given that most past research has been on athletes with overreaching rather than OTS.

Brain Dynamics: Methodological Issues and Applications in Psychiatric and Neurologic Diseases
NASA Astrophysics Data System (ADS)
Pezard, Laurent
The human brain is a complex dynamical system generating the EEG signal. Numerical methods developed to study complex physical dynamics have been used to characterize EEG since the mid-eighties. This endeavor raised several issues related to the specificity of EEG. Firstly, theoretical and methodological studies should address the major differences between the dynamics of the human brain and physical systems. Secondly, this approach of EEG signal should prove to be relevant for dealing with physiological or clinical problems. A set of studies performed in our group is presented here within the context of these two problematic aspects. After the discussion of methodological drawbacks, we review numerical simulations related to the high dimension and spatial extension of brain dynamics. Experimental studies in neurologic and psychiatric disease are then presented. We conclude that if it is now clear that brain dynamics changes in relation with clinical situations, methodological problems remain largely unsolved.

Transmasculine people assigned female sex at birth but who do not identify with this classification have traditionally received little consideration in the voice literature. Some voice researchers and clinicians suggest that transmasculine people do not need attention because testosterone treatment leads to a satisfactory masculinization of their voice organs and voices. Others, however, argue that transmasculine people are a heterogeneous group whose members might not share the same body type, gender identity or desire for medical approaches to gender transitioning. Therefore, testosterone-induced voice changes may not necessarily meet the needs and expectations of all transmasculine people. To evaluate the gender-related discursive and empirical data about transmasculine people's vocal situations to identify gaps in the current state of knowledge and to make suggestions for future voice research and clinical practice. A comprehensive review of peer-reviewed academic and clinical literature was conducted. Publications were identified by searching seven electronic databases and bibliographies of relevant articles. Thirty-one publications met inclusion criteria. Discourses and empirical data were analysed thematically. Potential problem areas that transmasculine people may experience were identified and the quality of evidence appraised. The extent and quality of voice research conducted with transmasculine people so far was found to be limited. There was mixed evidence to suggest that transmasculine people's vocal situations could be regarded as problematic. The diversity that characterizes the transmasculine population received little attention and the complexity of the factors that contribute to a successful or unsuccessful vocal communication of gender in this group appeared to be under-researched. While most transmasculine people treated with testosterone can expect a lowering of their pitch, it remains unclear whether the extent of the pitch change is enough to result in a voice that is recognized by others as male. More research into the different factors affecting transmasculine people's vocal situations that takes account of the diversity within the population is needed. © 2014 Royal College of Speech and Language Therapists.
Enhancing situational interest in pediatrics.
Beck, Gary L; Finken, David A; Stoolman, Sharon R

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

There are here described a number of basic principles underlying an effective clinical interview in psychiatric difficult situations (violent or suicidal patients, victims of serious physical and psychological damages, authors of inadequate or anti-social requests to the therapist). The aim of the present study is to provide the psychiatric operator with useful skills for the optimal management of the interview in difficult situations both at diagnostically and therapeutically level. The methodology was based on examination of the literature and personal experience of the authors. The authors highlighted 18 working hypothesis that may represent beneficial instruments in situations of difficult psychiatric interview. Further studies will deepen under the clinical, actuarial and statistical validity the principles covered in various clinical and crisis situations with difficulty to the interview, in relation also to specific types of patients for a more updated training of the operators in the field of mental health.
Cultural Similarities and Differences in Perceived Affordances of Situations for Big Five Behaviors
Church, A. Timothy; Katigbak, Marcia S.; del Prado, Alicia M.
2009-01-01
The perceived affordance or conduciveness of various situations for Big Five behaviors was investigated in the United States (N = 188) and the Philippines (N = 215). The basic proposition that different situations afford different trait-relevant behaviors was supported, at least in the perceptions of cultural informants. Cultural similarities exceeded differences, and in both cultures individuals perceived Big Five behaviors as expressed in if-then patterns of variation across situations. Americans and Filipinos showed some similarity in the general dimensions along which situations are construed, but meaningful differences in the construal of certain interpersonal situations were also observed. The findings contribute to efforts to integrate person and situation approaches in personality and social psychology. PMID:20401176
Medical Students' Understanding of Directed Questioning by Their Clinical Preceptors.
Lo, Lawrence; Regehr, Glenn
2017-01-01
Phenomenon: Throughout clerkship, preceptors ask medical students questions for both assessment and teaching purposes. However, the cognitive and strategic aspects of students' approaches to managing this situation have not been explored. Without an understanding of how students approach the question and answer activity, medical educators are unable to appreciate how effectively this activity fulfills their purposes of assessment or determine the activity's associated educational effects. A convenience sample of nine 4th-year medical students participated in semistructured one-on-one interviews exploring their approaches to managing situations in which they have been challenged with questions from preceptors to which they do not know the answer. Through an iterative and recursive analytic reading of the interview transcripts, data were coded and organized to identify themes relevant to the students' considerations in answering such questions. Students articulated deliberate strategies for managing the directed questioning activity, which at times focused on the optimization of their learning but always included considerations of image management. Managing image involved projecting not only being knowledgeable but also being teachable. The students indicated that their considerations in selecting an appropriate strategy in a given situation involved their perceptions of their preceptors' intentions and preferences as well as several contextual factors. Insights: The medical students we interviewed were quite sophisticated in their understanding of the social nuances of the directed questioning process and described a variety of contextually invoked strategies to manage the situation and maintain a positive image.

Transmasculine people assigned female gender at birth but who do not identify with this classification have traditionally received little consideration in the voice literature. Existing analyses tend to be focused on evaluating speaker voice characteristics, whereas other factors that contribute to the production of vocal gender have remained underexplored. Most studies rely on researcher-centred perspectives, whereas very little is known about how transmasculine people themselves experience and make sense of their vocal situations. To explore how participants described their subjective gender positionings; which gender attributions they wished to receive from others; which gender they self-attributed to their voices; which gender attributions they had received from others; and how far participants were satisfied with the gender-related aspects of their vocal situations. Transcripts of semi-structured interviews with 14 German-speaking transmasculine people served as the original data corpus. Sections in which participants described the gender-related aspects of their vocal situations and that were relevant to the current research objectives were selected and explored using qualitative content analysis. The analysis revealed diverse accounts pertaining to the factors that contribute to the production of vocal gender for individual participants and variable levels of satisfaction with vocal gender presentation and attribution. Transmasculine people need to be regarded as a heterogeneous population and clinical practice needs to follow a client-centred, individualized approach. © 2016 Royal College of Speech and Language Therapists.

Wieckiewicz, Mieszko; Paradowska-Stolarz, Anna; Wieckiewicz, Wlodzimierz
2014-01-01
In clinical practice, patients suffering from an occlusal parafunctional activity have increased. It can be observed that a negative influence of environment aggravates patient's health. The aim of this paper is to present the impact of environment and development of human civilization on the prevalence of bruxism and the correlation between them. The authors grasp the most relevant aspects of psychological and anthropological factors changing over time as well as their interactions and describe a relationship between chronic stress and bruxism. Current literature shows how contemporary lifestyle, working environment, diet, and habits influence the patient's psychoemotional situation and the way these factors affect the occluso-muscle condition.

Assess clinical studies regarding accuracy between virtual planning of computer-guided surgery and actual outcomes of dental implant placements in total edentulous alveolar ridges. A PubMed search was performed to identify only clinical studies published between 2011 and 2016, searching the following combinations of keywords: “Accuracy AND Computer-Assisted Surgery AND Dental Implants.” Study designs were identified using the terms: Case Reports, Clinical study, Randomized Controlled Trial, Systematic Reviews, Meta-Analysis, humans. Level of agreement between the authors in the study selection process was substantial (k = 0.767), and the study eligibility was considered excellent (k = 0.863). Seven articles were included in this review. They describe the use of bone and muco-supported guides, demonstrating angular deviations cervically and apically ranging from (minimum and maximum means), respectively, 1.85–8.4 (°), 0.17–2.17 (mm), and 0.77–2.86 (mm). Angular deviations obtained most inaccuracy in maxila. For cervical and apical deviations, accuracy was preponderantly lower in maxilla. Despite the similar deviations measurement approaches described, clinical relevance of this study may be useful to warn the surgeon that safety margins in clinical situations. PMID:29657542
The oncological patient in the palliative situation.
Eychmueller, Steffen; Zwahlen, Diana; Fliedner, Monica

Palliative care approaches the patient and his or her suffering with a biopsychosocial-spiritual model. Thus, it is the strength of palliative care to complement the diagnosis driven approach of medical cancer care by a problem and resources-based assessment, participatory care plan, and patient-directed interventions. Interventions need to reflect timely prognosis, target population (the patient, the family carer, the professional), and level of trust and remaining energy. In palliative care the relevance of psycho-oncological aspects in the care of the terminally ill is considerable in the understanding of the overall suffering of patients approaching death and their loved ones and in their care and support. There is little evidence to date in terms of clinical benefit of specific psycho-oncological interventions in the last months or weeks of life, but there is evidence on effects of stress reduction and reduced anxiety if locus of control can stay within the patient as long as possible. One major difficulty in psychosocial research at the end-of-life, however, is defining patient relevant outcomes.

Evidence-based clinical practice guidelines (CPGs) are defined as "statements that are scientifically reviewed about evidence and systematically developed to assist in the doctors' and patients' decision making in certain clinical situations." This recommendation aims to promote good clinical practice for the provision of safe and effective practices of conscious sedation in dentistry. The development of this clinical practice guideline was conducted by performing a systematic search of the literature for evidence-based CPGs. Existing guidelines, relevant systematic reviews, policy documents, legislation, or other recommendations were reviewed and appraised. To supplement this information, key questions were formulated by the Guideline Development Group and used as the basis for designing systematic literature search strategies to identify literature that may address these questions. Guideline documents were evaluated through a review of domestic and international databases for the development of a renewing of existing conscious sedation guidelines for dentistry. Clinical practice guidelines were critically appraised for their methodologies using Appraisal of guidelines for research and evaluation (AGREE) II. A total of 12 existing CPGs were included and 13 recommendations were made in a range of general, adult, and pediatric areas. The clinical practice guidelines for conscious sedation will be reviewed in 5 years' time for further updates to reflect significant changes in the field.

An interaction of drug with food, herbs, and dietary supplements is usually the consequence of a physical, chemical or physiologic relationship between a drug and a product consumed as food, nutritional supplement or over-the-counter medicinal plant. The current educational review aims at reminding to the prescribing physicians that the most clinically relevant drug-food interactions may not be strictly limited to those with grapefruit juice and with the Saint John's Wort herbal extract and may be responsible for changes in drug plasma concentrations, which in turn decrease efficacy or led to sometimes life-threatening toxicity. Common situations handled in clinical practice such as aging, concomitant medications, transplant recipients, patients with cancer, malnutrition, HIV infection and those receiving enteral or parenteral feeding may be at increased risk of drug-food or drug-herb interactions. Medications with narrow therapeutic index or potential life-threatening toxicity, e.g., the non-steroidal anti-inflammatory drugs, opioid analgesics, cardiovascular medications, warfarin, anticancer drugs and immunosuppressants may be at risk of significant drug-food interactions to occur. Despite the fact that considerable effort has been achieved to increase patient' and doctor's information and ability to anticipate their occurrence and consequences in clinical practice, a thorough and detailed health history and dietary recall are essential for identifying potential problems in order to optimize patient prescriptions and drug dosing on an individual basis as well as to increase the treatment risk/benefit ratio.

Smaller health care facilities especially clinics though believed to generate lesser quantum/categories of medical waste, the number of clinics/small health care settings are considerable. The movement to manage biomedical waste in a safe and scientific manner has gathered momentum among the medium and large hospitals in Bangalore, but there has been a little understanding and focus on the smaller health care facilities/clinics in this aspect. It is important to gather evidence regarding the current situation of bio-medical waste (BMW) management and issues in smaller health care settings, so as to expand the safe management to all points of generation in Bangalore and will also help to plan relevant interventional strategies for the same. Hence an exploratory study was conducted to assess the current situation and issues in management of BMW among small health care facilities (sHCF). This cross sectional study was conducted in T. Dasarahalli (ward number 15) under Bruhat Bengaluru Mahanagar Palike (BBMP) of Bangalore. Data was collected from a convenient sample of 35 nursing homes (<50 beds) and clinics in December 2011. The results of this study indicate that 3 (20 %) of nursing homes had a Policy for Health Care Waste Management, though committees for Infection control and Hospital waste management were absent. Recording system like injury and waste management registers were non-existent. In our study the Common Bio-medical Waste Treatment Facility operator collected waste from 28 (80 %) of the sHCF. Segregation at the point of generation was present in 22 (62.9 %) of the sHCF. Segregation process was compliant as per BMW rules 1998 among 5 (16.1 %) of the sHCF. 18 sHCF workers were vaccinated with hepatitis B and tetanus. Deficiencies were observed in areas of containment, sharps management and disinfection. It was observed that though the quantum and category of waste generated was limited there exist deficiencies which warrant initiation of system development measures including capacity building.
Attention deficit-hyperactivity disorder, comorbidities, and risk situations.

Attention deficit/hyperactivity disorder (ADHD) is highly prevalent, and its symptoms often represent a significant public health problem; thus, the aim of this study was to verify emergency situations caused by certain comorbidities, or by exposing the patient to a higher risk of accidents. A literature search was carried out in the PubMed database between the years 1992 and 2012, using the key words "adhd", "urgency", "comorbidity", "substance disorder", "alcohol", "eating disorder", "suicide", "trauma", "abuse", "crime", "internet", "videogame", "bullying", and their combinations. The selection considered the most relevant articles according to the scope of the proposed topic, performed in a non-systematic way. Several situations were observed in which ADHD is the most relevant psychiatric diagnosis in relation to its urgency, such as the risk of accidents, suicide risk and addition, exposure to violence, or risk of internet abuse or sexual abuse; or when ADHD is the most prevalent comorbidity and is also correlated with emergency situations, such as in bipolar and eating disorders. The results show several comorbidities and risk situations involving the diagnosis of ADHD, thus reinforcing the importance of their identification for the adequate treatment of this disorder.

Statistical significance has been used extensively to evaluate the results of research studies. Nevertheless, it offers only limited information to clinicians. The assessment of clinical relevance can facilitate the interpretation of the research results into clinical practice. The objective of this study was to explore different methods to evaluate the clinical relevance of the results using a cross-sectional study as an example comparing different neck outcomes between subjects with temporomandibular disorders and healthy controls. Subjects were compared for head and cervical posture, maximal cervical muscle strength, endurance of the cervical flexor and extensor muscles, and electromyographic activity of the cervical flexor muscles during the CranioCervical Flexion Test (CCFT). The evaluation of clinical relevance of the results was performed based on the effect size (ES), minimal important difference (MID), and clinical judgement. The results of this study show that it is possible to have statistical significance without having clinical relevance, to have both statistical significance and clinical relevance, to have clinical relevance without having statistical significance, or to have neither statistical significance nor clinical relevance. The evaluation of clinical relevance in clinical research is crucial to simplify the transfer of knowledge from research into practice. Clinical researchers should present the clinical relevance of their results. Copyright © 2011 Elsevier Ltd. All rights reserved.

Formation of resilient biofilms on medical devices colonized by pathogenic microorganisms is a major cause of health-care associated infection. While in vitro biofilm analyses led to promising anti-biofilm approaches, little is known about their translation to in vivo situations and on host contribution to the in vivo dynamics of infections on medical devices. Here we have developed an in vivo model of long-term bacterial biofilm infections in a pediatric totally implantable venous access port (TIVAP) surgically placed in adult rats. Using non-invasive and quantitative bioluminescence, we studied TIVAP contamination by clinically relevant pathogens, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Staphylococcus epidermidis, and we demonstrated that TIVAP bacterial populations display typical biofilm phenotypes. In our study, we showed that immunocompetent rats were able to control the colonization and clear the bloodstream infection except for up to 30% that suffered systemic infection and death whereas none of the immunosuppressed rats survived the infection. Besides, we mimicked some clinically relevant TIVAP associated complications such as port-pocket infection and hematogenous route of colonization. Finally, by assessing an optimized antibiotic lock therapy, we established that our in vivo model enables to assess innovative therapeutic strategies against bacterial biofilm infections.

Purpose: To study Cherenkov light emission in plastic scintillation detectors (PSDs) from a theoretical point of view to identify situations that may arise where the calibration coefficient obtained in one condition is not applicable to another condition. By identifying problematic situations, we hope to provide guidance on how to confidently use PSDs. Methods: Cherenkov light emission in PSD was modelled using basic physical principles. In particular, changes in refractive index as a function of wavelength were accounted for using the Sellmeier empirical equation. Both electron and photon beams were considered. For photons, realistic distributions of secondary charged particles were calculatedmore » using Klein-Nishina’s formula. Cherenkov production and collection in PSDs were studied for a range of parameters including beam energy, charged particle momentum distribution, detector orientation and material composition. Finally, experimental validation was made using a commercial plastic scintillation detector. Results: In specific situations, results show that the Cherenkov spectrum coupled in the PSD can deviate from its expected behaviour (i.e. one over the square of the wavelength). In these cases were the model is realistic it is possible to see a peak wavelength instead of a monotonically decreasing function. Consequences of this phenomenon are negligible when the momentum of charged particle is distributed randomly, but in some clinically relevant cases, such as an electron beam at depth close to R50 or for photon beams with minimal scatter component, the value of the calibration coefficient can be altered. Experimental tests with electron beams showed changes in the Cherenkov light ratio, the parameter used in the calibration of PSDs, up to 2–3% depending on the PSD orientation. Conclusion: This work is the first providing a physical explanation for apparent change in PSD calibration coefficient. With this new information at hand, it will be possible to better guide the clinical use of PSDs.« less
Perceived levels of frustration during clinical situations in athletic training students.

Athletic training students (ATSs) are involved in various situations during the clinical experience that may cause them to express levels of frustration. Understanding levels of frustration in ATSs is important because frustration can affect student learning, and the clinical experience is critical to their development as professionals. To explore perceived levels of frustration in ATSs during clinical situations and to determine if those perceptions differ based on sex. Cross-sectional study with a survey instrument. A total of 14 of 19 professional, undergraduate athletic training programs accredited by the Commission on Accreditation of Athletic Training Education in Pennsylvania. Of a possible 438 athletic training students, 318 (72.6%) completed the survey. The Athletic Training Student Frustration Inventory was developed and administered. The survey gathered demographic information and included 24 Likert-scale items centering on situations associated with the clinical experience. Descriptive statistics were computed on all items. The Mann-Whitney U was used to evaluate differences between male and female students. A higher level of frustration was perceived during the following clinical situations: lack of respect by student-athletes and coaching staffs, the demands of the clinical experience, inability of ATSs to perform or remember skills, and ATSs not having the opportunity to apply their skills daily. Higher levels of frustration were perceived in female than male ATSs in several areas. Understanding student frustration during clinical situations is important to better appreciate the clinical education experience. Low levels of this emotion are expected; however, when higher levels exist, learning can be affected. Whereas we cannot eliminate student frustrations, athletic training programs and preceptors need to be aware of this emotion in order to create an environment that is more conducive to learning.

In modern practice, doctors who outright lie to their patients are often condemned, yet those who employ non-lying deceptions tend to be judged less critically. Some areas of non-disclosure have recently been challenged: not telling patients about resuscitation decisions; inadequately informing patients about risks of alternative procedures and withholding information about medical errors. Despite this, there remain many areas of clinical practice where non-disclosures of information are accepted, where lies about such information would not be. Using illustrative hypothetical situations, all based on common clinical practice, we explore the extent to which we should consider other deceptive practices in medicine to be morally equivalent to lying. We suggest that there is no significant moral difference between lying to a patient and intentionally withholding relevant information: non-disclosures could be subjected to Bok's ‘Test of Publicity’ to assess permissibility in the same way that lies are. The moral equivalence of lying and relevant non-disclosure is particularly compelling when the agent's motivations, and the consequences of the actions (from the patient's perspectives), are the same. We conclude that it is arbitrary to claim that there is anything inherently worse about lying to a patient to mislead them than intentionally deceiving them using other methods, such as euphemism or non-disclosure. We should question our intuition that non-lying deceptive practices in clinical practice are more permissible and should thus subject non-disclosures to the same scrutiny we afford to lies.

How to: evaluate a diagnostic test.

The development of an in vitro diagnostic test from a good idea to a clinically relevant tool takes several steps, with more stringent requirements at every step. This article aims to summarize the necessary questions to be asked about a test and to illustrate study designs answering these questions. We also aim to relate the Regulation (EU) 2017/746 to the needs of evidence-based diagnostic testing, where applicable. We used literature on evidence-based diagnostics, a text book on clinical trials in the development and marketing of medical devices and the English version of Regulation 2017/746 of the European Parliament and of the Council on in vitro diagnostic medical devices. The combination of different test uses and different stages of development determine the required test characteristics and suitability of study designs. In an earlier stage of test development it may be crucial to know whether a test can differentiate diseased persons from healthy controls, while this tells us little about how a test will perform in practice. Later stages focus on the diagnostic accuracy of a test in a clinically relevant situation. However, a test that perfectly distinguishes between patients with and without a certain condition may still have little effect on patient outcomes. Therefore, randomized controlled trials of testing may be needed, as well as post-marketing monitoring. Both researchers and users of tests need to be aware of the limitations of diagnostic test accuracy and realize that accuracy is only indirectly linked to people's health status. Copyright © 2018.

Thinking like a nurse: a research-based model of clinical judgment in nursing.
Tanner, Christine A
2006-06-01
This article reviews the growing body of research on clinical judgment in nursing and presents an alternative model of clinical judgment based on these studies. Based on a review of nearly 200 studies, five conclusions can be drawn: (1) Clinical judgments are more influenced by what nurses bring to the situation than the objective data about the situation at hand; (2) Sound clinical judgment rests to some degree on knowing the patient and his or her typical pattern of responses, as well as an engagement with the patient and his or her concerns; (3) Clinical judgments are influenced by the context in which the situation occurs and the culture of the nursing care unit; (4) Nurses use a variety of reasoning patterns alone or in combination; and (5) Reflection on practice is often triggered by a breakdown in clinical judgment and is critical for the development of clinical knowledge and improvement in clinical reasoning. A model based on these general conclusions emphasizes the role of nurses' background, the context of the situation, and nurses' relationship with their patients as central to what nurses notice and how they interpret findings, respond, and reflect on their response.

The synchronous use of chemically different contrast media in the same body compartment is a challenge for the radiologist, whether it is scheduled or unexpected. However, to inject contrast media containing iodine and gadolinium at the same time can be a prerequisite for the examination of several organs or organ systems. Unlike other topics of contrast-enhanced imaging procedures, the difficulties encountered with double contrast injections have been widely ignored in the literature. In the absence of reliable data from experimental and clinical studies the radiologist is dependent on case reports, information provided by the contrast media manufacturers, personal communications, mostly scanty personal experiences and a skilful time management, in order to overcome the situation. Only the combination of X-ray, computed tomography and magnetic resonance arthrography can be performed without another thought. However, the more or less synchronous vascular application of contrast media containing iodine and gadolinium requires vigilance. The more seriously ill the patient is, the more caution is advised even if the decision on the combined administration has to be reached urgently. The following overview gives a description of the properties of contrast media containing iodine and gadolinium as far as interactions following simultaneous administration are concerned. Subsequently, the clinically relevant situations and constellations are outlined and analyzed.

Despite increasing demand for structured processes to guide clinical handover, nursing handover tools are limited in the intensive care unit. The study aim was to identify key items to include in a minimum dataset for intensive care nursing team leader shift-to-shift handover. This focus group study was conducted in a 21-bed medical/surgical intensive care unit in Australia. Senior registered nurses involved in team leader handovers were recruited. Focus groups were conducted using a nominal group technique to generate and prioritise minimum dataset items. Nurses were presented with content from previous team leader handovers and asked to select which content items to include in a minimum dataset. Participant responses were summarised as frequencies and percentages. Seventeen senior nurses participated in three focus groups. Participants agreed that ISBAR (Identify-Situation-Background-Assessment-Recommendations) was a useful tool to guide clinical handover. Items recommended to be included in the minimum dataset (≥65% agreement) included Identify (name, age, days in intensive care), Situation (diagnosis, surgical procedure), Background (significant event(s), management of significant event(s)) and Recommendations (patient plan for next shift, tasks to follow up for next shift). Overall, 30 of the 67 (45%) items in the Assessment category were considered important to include in the minimum dataset and focused on relevant observations and treatment within each body system. Other non-ISBAR items considered important to include related to the ICU (admissions to ICU, staffing/skill mix, theatre cases) and patients (infectious status, site of infection, end of life plan). Items were further categorised into those to include in all handovers and those to discuss only when relevant to the patient. The findings suggest a minimum dataset for intensive care nursing team leader shift-to-shift handover should contain items within ISBAR along with unit and patient specific information to maintain continuity of care and patient safety across shift changes.

Virtual reality applications for diagnosis, risk assessment and therapy of child abusers.
Fromberger, Peter; Jordan, Kirsten; Müller, Jürgen L
2018-03-01
Despite the successful application of virtual reality (VR) in a wide variety of mental disorders and the obvious potentials that VR provides, the use of VR in the context of criminology and forensic psychology is sparse. For forensic mental health professionals, VR provides some advantages that outrun general advantages of VR, e.g., ecological validity and controllability of social situations. Most important seems to be the unique possibility to expose offenders and to train coping skills in virtual situations, which are able to elicit disorder-relevant behavior-without endangering others. VR has already been used for the assessment of deviant sexual interests, for testing the ability to transfer learned coping skills communicated during treatment to behavior, and for risk assessment of child abusers. This article reviews and discusses these innovative research projects with regard to their impact on current clinical practice regarding risk assessment and treatment as well as other implementations of VR applications in forensic mental health. Finally, ethical guidelines for VR research in forensic mental health are provided. Copyright © 2018 John Wiley & Sons, Ltd.

Shared decision-making (SDM) is a patient-centred approach in which clinicians and patients work side-by-side to decide together on the best course of action for each patient's particular situation. Six key elements of SDM can be distinguished: situation diagnosis, choice awareness, option clarification, discussion of harms and benefits, deliberation of patient preferences and making the decision. Decision aids (DAs) are tools that facilitate SDM. The impact of DAs for chronic illnesses on SDM, clinical and patient reported outcomes remains uncertain. We will perform a systematic review aiming to describe (a) which SDM elements are incorporated in DAs for adult patients with chronic conditions and (b) the effects of DA use on SDM, clinical and patient reported outcomes. This manuscript reports on the protocol for this systematic review. The following databases will be searched for relevant articles: PubMed, Embase, Web of Science, CINAHL and PsycINFO, from their inception to October 2016. We will ascertain ongoing research by querying experts and searching trial registries. To enhance feasibility, we will limit the review to randomized controlled trials (RCTs) including patients with chronic cardiovascular and/or respiratory diseases and/or diabetes. SDM elements incorporated in DAs, DA effects and DA itself will be described. This study will characterize DAs for chronic illness and will provide an overview of their effects on SDM, clinical and patient reported outcomes. We anticipate this review will bring to light knowledge gaps and inform further research into the design and use of DAs for patients with chronic conditions.

Today, the main challenge for researchers is to develop new technologies which may help to improve the diagnoses of cardiovascular disease (CVD), thereby reducing healthcare costs and improving the quality of life for patients. This study aims to show the utility of biomedical shirt-based electrocardiography (ECG) monitoring of patients with CVD in different clinical situations using the Nuubo® ECG (nECG) system. An investigator-initiated, multicenter, prospective observational study was carried out in a cardiology (adult and pediatric) and cardiac rehabilitation wards. ECG monitoring was used with the biomedical shirt in the following four independent groups of patients: 1) 30 patients after pulmonary vein isolation (PVI), 2) 30 cardiac resynchronization therapy (CRT) recipients, 3) 120 patients during cardiac rehabilitation after myocardial infarction, and 4) 40 pediatric patients with supraventricular tachycardia (SVT) before electrophysiology study. Approval for all study groups was obtained from the institutional review board. The biomedical shirt captures the electrocardiographic signal via textile electrodes integrated into a garment. The software allows the visualization and analysis of data such as ECG, heart rate, arrhythmia detecting algorithm and relative position of the body is captured by an electronic device. The major advantages of the nECG system are continuous ECG monitoring during daily activities, high quality of ECG recordings, as well as assurance of a proper adherence due to adequate comfort while wearing the shirt. There are only a few studies that have examined wearable systems, especially in pediatric populations. This study is registered in ClinicalTrials.gov: Identifier NCT03068169. (Cardiol J 2018; 25, 1: 52-59).

Overall survival (OS) is the gold standard for the demonstration of a clinical benefit in cancer trials. Replacement of OS by a surrogate endpoint allows to reduce trial duration. To date, few surrogate endpoints have been validated in digestive oncology. The aim of this study was to draw up an ordered list of potential surrogate endpoints for OS in digestive cancer trials, by way of a survey among clinicians and methodologists. Secondary objective was to obtain their opinion on surrogacy and quality of life (QoL). In 2007 and 2008, self administered sequential questionnaires were sent to a panel of French clinicians and methodologists involved in the conduct of cancer clinical trials. In the first questionnaire, panellists were asked to choose the most important characteristics defining a surrogate among six proposals, to give advantages and drawbacks of the surrogates, and to answer questions about their validation and use. Then they had to suggest potential surrogate endpoints for OS in each of the following tumour sites: oesophagus, stomach, liver, pancreas, biliary tract, lymphoma, colon, rectum, and anus. They finally gave their opinion on QoL as surrogate endpoint. In the second questionnaire, they had to classify the previously proposed candidate surrogates from the most (position #1) to the least relevant in their opinion.Frequency at which the endpoints were chosen as first, second or third most relevant surrogates was calculated and served as final ranking. Response rate was 30% (24/80) in the first round and 20% (16/80) in the second one. Participants highlighted key points concerning surrogacy. In particular, they reminded that a surrogate endpoint is expected to predict clinical benefit in a well-defined therapeutic situation. Half of them thought it was not relevant to study QoL as surrogate for OS.DFS, in the neoadjuvant settings or early stages, and PFS, in the non operable or metastatic settings, were ranked first, with a frequency of more than 69% in 20 out of 22 settings. PFS was proposed in association with QoL in metastatic primary liver and stomach cancers (both 81%). This composite endpoint was ranked second in metastatic oesophageal (69%), colorectal (56%) and anal (56%) cancers, whereas QoL alone was also suggested in most metastatic situations.Other endpoints frequently suggested were R0 resection in the neoadjuvant settings (oesophagus (69%), stomach (56%), pancreas (75%) and biliary tract (63%)) and response. An unexpected endpoint was metastatic PFS in non operable oesophageal (31%) and pancreatic (44%) cancers. Quality and results of surgical procedures like sphincter preservation were also cited as eligible surrogate endpoints in rectal (19%) and anal (50% in case of localized disease) cancers. Except for alpha-FP kinetic in hepatocellular carcinoma (13%) and CA19-9 decline (6%) in pancreas, few endpoints based on biological or tumour markers were proposed. The overall results should help prioritise the endpoints to be statistically evaluated as surrogate for OS, so that trialists and clinicians can rely on endpoints that ensure relevant clinical benefit to the patient.

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting. © The Author 2017.

Ethical principles in health research and review process.
Tangwa, Godfrey B
2009-11-01
In this paper I want to reflect on the fundamental ethical principles and their application in different particular contexts, especially in health research and the ethics review process. Four fundamental ethical principles have been identified and widely discussed in bioethical literature. These principles namely are: autonomy or respect for others, beneficence, non-maleficence and justice. These principles have cross-cultural validity, relevance and applicability. Every real-life situation and every concrete particular case in which ethical decision-making is called-for is unique and different from all others; but the same fundamental ethical principles are relevant and used in addressing all such cases and situations. Very often ethical problems will present themselves in the form of dilemmas and it is then necessary to use the same fundamental principles to analyze the situations, to argue persuasively and cogently with competence for the best options or choices in such situations. The issues I will be dealing with in this paper are necessarily more abstract and theoretical, but we will be discussing them from a very practical viewpoint and impulse, with a view to application in concrete real-life situations. The paper ends with some sample practical examples of cases that the reader can use to test his/her grasp of the principles, how to apply them, how to balance them in differing situations and contexts and how to adjudicate between them when they seem to be in conflict.

Place names play an important role in Borderlands Situation topics, while current focused crawling methods treat them in the same way as other common keywords, which may lead to the omission of many useful web pages. In the paper, place names in web pages and their spatial relations were firstly discussed. Then, a focused crawling method named KSRs-FC was proposed to deal with the collection of situation information about borderlands. In this method, place names and common keywords were represented separately, and some of the spatial relations related to web pages crawling were used in the relevance calculation between the given topic and web pages. Furthermore, an information collection system for borderlands situation analysis was developed based on KSRs-FC. Finally, F-Score method was adopted to quantitatively evaluate this method by comparing with traditional method. Experimental results showed that the F-Score value of the proposed method increased by 11% compared to traditional method with the same sample data. Obviously, KSRs-FC method can effectively reduce the misjudgement of relevant webpages.
[Design of a conceptual model on the transference of public health research results in Honduras].
Macías-Chapula, César A
2012-01-01
To design a conceptual model on the transference of public health research results at the local, context level. Using systems thinking concepts, a soft systems approach (SSM) was used to analyse and solve what was perceived as a problem situation related to the transference of research results within Honduras public health system. A bibliometric analysis was also conducted to enrich the problem situation. Six root definitions were defined and modeled as relevant to the expressed problem situation. This led to the development of the conceptual model. The model obtained identified four levels of resolution as derived from the human activities involved in the transference of research results: 1) those of the researchers; 2) the information/documentation professionals; 3) health staff; and 4) the population/society. These actors/ clients and their activities were essential to the functioning of the model since they represent what the model is and does. SSM helped to design the conceptual model. The bibliometric analysis was relevant to construct the rich image of the problem situation.
The idealized self and the situated self as predictors of employee work behaviors.
Farmer, Steven M; Van Dyne, Linn
2010-05-01
This article presents a model integrating research on idealized and situated selves. Our key premise is that identity-relevant behaviors are most likely to occur in the workplace when identities are psychologically central and activating forces make those identities salient. Analysis of matched data from 278 employees, supervisors, and organizational records generally supported our model. Helping identity and industrious work identity were positively associated with related role behaviors only when time-based occupancy in the role of organization member was high. Industrious work identity was positively associated with role behaviors only when reflected appraisals from coworkers were consistent with that identity. In contrast, reflected appraisal of helping identity had an independent relationship with identity-relevant role behaviors. Results demonstrate the importance of theory linking the idealized self and the situated self to understanding identity relations with work performances.

Practitioners and stakeholders involved in environmental and risk assessment and decision-making efforts have access to a growing list of policies and guidance for implementing good process. The advice is often general. There is little understanding of how situation specific features are relevant in new circumstances. In a series of ten case studies we investigated how people’s (a) perceptions of the context, (b) preferences for outcomes, and (c) affiliations, experiences and motivations are related to their preferences for process features in a particular situation. The cases are in three policy areas: watershed management, forestry management, and clean-up and public health management of radioactively contaminated sites. We conclude this paper with a discussion of how the results can inform process design. Process design should be based on a diagnostic approach that specifically assesses relevant situational characteristics.

Power and affordances: when the situation has more power over powerful than powerless individuals.
Guinote, Ana
2008-08-01
Six studies examined how power affects responses to situational affordances. Participants were assigned to a powerful or a powerless condition and were exposed to various situations that afford different classes of behavior. Study 1 examined behavior intentions for weekdays and weekends. Studies 2 and 3 focused on responses to imaginary social and work situations. Study 4 examined planned behavior for winter and summer days. Finally, Studies 5 and 6 examined behavior and attention in the presence of situation-relevant and irrelevant information. Consistently across these studies, powerful individuals acted more in situation-consistent ways, and less in situation-inconsistent ways, compared with powerless individuals. These findings are interpreted as a result of the greater tendency for powerful individuals to process information selectively in line with the primary factors that drive cognition, such as affordances. One consequence of these findings is that powerful individuals change behavior across situations more than powerless individuals.

The standard regulatory core battery of genotoxicity tests generally includes 2 or 3 validated tests with at least one in vitro test in bacteria and one in vitro test on cell cultures. However, limitations in in vitro genotoxicity testing may exist at many levels. The knowledge of the underlying mechanisms of genotoxicity is particularly useful to assess the level of relevance for the in vivo situation. In order to avoid wrong conclusions regarding the actual genotoxicity status of any test substance, it appears very important to be aware of the various origins of related bias leading to 'false positives and negatives' by using in vitro methods. Among these, mention may be made on the metabolic activation system, experimental (extreme) conditions, specificities of the test systems implemented, cell type used etc. The knowledge of the actual 'limits' of the in vitro test systems used is clearly an advantage and may contribute to avoid some pitfalls in order to better assess the level of relevance for the in vivo situation.

Purpose: To provide the professional medical physicists with adequate competencies and skills in order to help them get prepared to support Nuclear or Radiological Emergency (NRE) situations. Methods: Although clinical medical physicists working have in-depth knowledge in radiation dosimetry, including dose reconstruction and dose measurements, they are usually not involved in NRE situations. However, in a few instances where medical physicists were involved in NREs, it appeared that many lacked specific knowledge and skills that are required in such situations. This lack of specific knowledge and skills is probably due to the fact that most current medical physics curricula domore » not include a specific module on this topic. As a response to this finding, the IAEA decided to initiate a project to develop a specific training package to help prepare medical physicists to support NRE situations. The training package was developed with the kind support of the Government of Japan and in collaboration with Fukushima Medical University (FMU) and the National Institute of Radiological Sciences (NIRS). Results: The first International Workshop to test the training package was held in Fukushima, Japan in June 2015. It consisted of lectures, demonstrations, simulation, role play, and practical sessions followed by discussions. The training was delivered through 14 modules which were prepared with the support of 12 lecturers. A knowledge assessment test was done before the workshop, followed by the same test done at the end of the Workshop, to assess the knowledge acquired during the training. Conclusion: The Workshop was successfully implemented. The overall rating of the workshop by the participants was excellent and all participants reported that they acquired a good understanding of the main issues that are relevant to medical physics support in case of NRE situations. They are expected to disseminate the knowledge to other medical physicists in their countries.« less

Bariatric surgery is today the most effective long-term therapy for the management of patients with severe obesity, and its use is recommended by the relevant guidelines of the management of obesity in adults. Bariatric surgery is in general safe and effective, but it can cause new clinical problems and is associated with specific diagnostic, preventive and therapeutic needs. For clinicians, the acquisition of special knowledge and skills is required in order to deliver appropriate and effective care to the post-bariatric patient. In the present recommendations, the basic notions needed to provide first-level adequate medical care to post-bariatric patients are summarised. Basic information about nutrition, management of co-morbidities, pregnancy, psychological issues as well as weight regain prevention and management is derived from current evidences and existing guidelines. A short list of clinical practical recommendations is included for each item. It remains clear that referral to a bariatric multidisciplinary centre, preferably the one performing the original procedure, should be considered in case of more complex clinical situations.

Computer vision syndrome-A common cause of unexplained visual symptoms in the modern era.
Munshi, Sunil; Varghese, Ashley; Dhar-Munshi, Sushma
2017-07-01
The aim of this study was to assess the evidence and available literature on the clinical, pathogenetic, prognostic and therapeutic aspects of Computer vision syndrome. Information was collected from Medline, Embase & National Library of Medicine over the last 30 years up to March 2016. The bibliographies of relevant articles were searched for additional references. Patients with Computer vision syndrome present to a variety of different specialists, including General Practitioners, Neurologists, Stroke physicians and Ophthalmologists. While the condition is common, there is a poor awareness in the public and among health professionals. Recognising this condition in the clinic or in emergency situations like the TIA clinic is crucial. The implications are potentially huge in view of the extensive and widespread use of computers and visual display units. Greater public awareness of Computer vision syndrome and education of health professionals is vital. Preventive strategies should form part of work place ergonomics routinely. Prompt and correct recognition is important to allow management and avoid unnecessary treatments. © 2017 John Wiley & Sons Ltd.

Drug-induced toxicity is a significant problem in clinical care. A key problem here is a general understanding of the molecular mechanisms accompanying the transition from desired drug effects to adverse events following administration of either therapeutic or toxic doses, in particular within a patient context. Here, a comparative toxicity analysis was performed for fifteen hepatotoxic drugs by evaluating toxic changes reflecting the transition from therapeutic drug responses to toxic reactions at the cellular level. By use of physiologically-based pharmacokinetic modeling, in vitro toxicity data were first contextualized to quantitatively describe time-resolved drug responses within a patient context. Comparatively studying toxic changes across the considered hepatotoxicants allowed the identification of subsets of drugs sharing similar perturbations on key cellular processes, functional classes of genes, and individual genes. The identified subsets of drugs were next analyzed with regard to drug-related characteristics and their physicochemical properties. Toxic changes were finally evaluated to predict both molecular biomarkers and potential drug-drug interactions. The results may facilitate the early diagnosis of adverse drug events in clinical application. PMID:28151932

Practical relevance: Dermatophytosis (ringworm) is a superficial fungal skin disease of cats that, depending on the geographic region and practice caseload, may be encountered uncommonly through to commonly. This is a self-curing disease in an immunocompetent cat. Global importance: Dermatophytosis is prevalent worldwide and is one of a number of zoonotic skin diseases that cat owners are at risk of contracting. Clinical challenges: Dermatophytosis causes non-specific signs of hair loss, erythema and scaling, making it a differential diagnosis for many skin diseases of cats. The fact that this disease is infectious and contagious, and does not have any one classic clinical presentation, makes knowledge of diagnostic tools important in detection. The veterinarian’s role is in early disease recognition and institution of appropriate therapy to hasten resolution of the disease. Aim: The focus of this article is to provide an update and review of the most pertinent aspects that may be helpful in the management of dermatophytosis in any single or multiple cat situation. Evidence base: Where appropriate, evidence from the literature is used to supplement a summary of the author’s clinical experience and research in feline dermatophytosis. PMID:24794038
Engagement and practical wisdom in clinical practice: a phenomenological study.
Saraga, Michael; Boudreau, Donald; Fuks, Abraham
2018-05-08
In order to understand the lived experiences of physicians in clinical practice, we interviewed eleven expert, respected clinicians using a phenomenological interpretative methodology. We identified the essence of clinical practice as engagement. Engagement accounts for the daily routine of clinical work, as well as the necessity for the clinician to sometimes trespass common boundaries or limits. Personally engaged in the clinical situation, the clinician is able to create a space/time bubble within which the clinical encounter can unfold. Engagement provides an account of clinical practice as a unitary lived experience. This stands in stark contrast to the prevailing notion, referred to as a dual discourse, that describes medicine as the addition of humanism to science. Drawing on Aristotle's notion of phronesis and Sartre's definition of the situation, we illustrate how this novel perspective entwines clinical practice, the person of the clinician, and the clinician's situation.

The ultimate goal of chronic myeloid leukemia management in the tyrosine kinase inhibitor (TKI) era for patients who obtain deep molecular responses is maintaining a durable off-treatment response after treatment discontinuation; this situation is called treatment-free remission (TFR). Knowledge accumulated during the last 10 years justifies moving TFR strategies from research to clinical practice. Twenty experts from the French Chronic Myeloid Leukemia Study Group (France Intergroupe des Leucémies Myéloïdes Chroniques), including 17 hematologists, 2 molecular biologists, and 1 cytogeneticist, critically reviewed published data with the goal of developing evidence-based recommendations for TKI discontinuation in clinical practice. Clinically relevant questions were addressed, including the selection of candidate patients (with known prognostic factors for outcomes taken into account), detailed monitoring procedures during the treatment-free phase, a definition of relapse requiring therapy resumption, and monitoring after treatment reintroduction. This work presents consensus statements with the aim of guiding physicians and biologists by means of pragmatic recommendations for safe TKI discontinuation in daily practice.

Implementation of research findings in patient care ideally will follow in a continuous cycle, and clinical questions from practitioners should stimulate research. Even in the most optimal situations, there will be a gap between the steady flow of new findings from research and their eventual implementation in clinical practice. In the clinical practice of temporomandibular disorders and orofacial pain (TMD/OFP) simple cases outnumber the more complex cases by far. Therefore, research implications for the general dental practitioner, whose patients are rarely represented in research populations, may differ from what is published and taught. Treatment options like counselling, occlusal treatments (reversible as a rule and irreversible by exception) and physiotherapy can be very successful in the hands of the general dental practitioner. European dental schools should define additional amendments to the recently proposed profile and competencies for the European dentist, in order to focus on the relevant and current knowledge on temporomandibular disorders and orofacial pain. These amendments should address the adequate diagnosis and management of non-complex TMD cases and the need to refer to a TMD/OFP specialist in complex cases. Professional organizations such as the European Academy of Craniomandibular disorders can endorse better TMD/OFP education and training.

Pharmacovigilance contributes to health care. However, direct access to the underlying data for academic institutions and individual physicians or pharmacists is intricate, and easily employable analysis modes for everyday clinical situations are missing. This underlines the need for a tool to bring pharmacovigilance to the clinics. To address these issues, we have developed OpenVigil FDA, a novel web-based pharmacovigilance analysis tool which uses the openFDA online interface of the Food and Drug Administration (FDA) to access U.S. American and international pharmacovigilance data from the Adverse Event Reporting System (AERS). OpenVigil FDA provides disproportionality analyses to (i) identify the drug most likely evoking a new adverse event, (ii) compare two drugs concerning their safety profile, (iii) check arbitrary combinations of two drugs for unknown drug-drug interactions and (iv) enhance the relevance of results by identifying confounding factors and eliminating them using background correction. We present examples for these applications and discuss the promises and limits of pharmacovigilance, openFDA and OpenVigil FDA. OpenVigil FDA is the first public available tool to apply pharmacovigilance findings directly to real-life clinical problems. OpenVigil FDA does not require special licenses or statistical programs.
Situational awareness in the commercial aircraft cockpit - A cognitive perspective

Adams, Marilyn J.; Pew, Richard W.

A cognitive theory is presented that has relevance for the definition and assessment of situational awareness in the cockpit. The theory asserts that maintenance of situation awareness is a constructive process that demands mental resources in competition with ongoing task performance. Implications of this perspective for assessing and improving situational awareness are discussed. It is concluded that the goal of inserting advanced technology into any system is that it results in an increase in the effectiveness, timeliness, and safety with which the system's activities can be accomplished. The inherent difficulties of the multitask situation are very often compounded by the introduction of automation. To maximize situational awareness, the dynamics and capabilities of such technologies must be designed with thorough respect for the dynamics and capabilities of human information-processing.

The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

In this paper we describe our newly constructed Family Coping Coding System. This scheme was constructed to identify family coping strategies that involve appraisal, problem solving, and emotion management dimensions. We discuss the theoretical rationale, meanings and reliability of the coping codes, and illustrate them through excerpts drawn from family discussions of a recent stressful situation (the onset of a chronic or acute illness in an adolescent member). Finally, we consider the clinical research relevance of this new assessment technique, exemplifying this potential with respect to medical compliance. We present analyses of two families with diabetic adolescents who strikingly differ with respect to compliance, and explore which family coping strategies may be predictive of an adolescent's favorable or problematic compliance to diabetes management.
Relevant, irredundant feature selection and noisy example elimination.
Lashkia, George V; Anthony, Laurence

In many real-world situations, the method for computing the desired output from a set of inputs is unknown. One strategy for solving these types of problems is to learn the input-output functionality from examples in a training set. However, in many situations it is difficult to know what information is relevant to the task at hand. Subsequently, researchers have investigated ways to deal with the so-called problem of consistency of attributes, i.e., attributes that can distinguish examples from different classes. In this paper, we first prove that the notion of relevance of attributes is directly related to the consistency of attributes, and show how relevant, irredundant attributes can be selected. We then compare different relevant attribute selection algorithms, and show the superiority of algorithms that select irredundant attributes over those that select relevant attributes. We also show that searching for an "optimal" subset of attributes, which is considered to be the main purpose of attribute selection, is not the best way to improve the accuracy of classifiers. Employing sets of relevant, irredundant attributes improves classification accuracy in many more cases. Finally, we propose a new method for selecting relevant examples, which is based on filtering the so-called pattern frequency domain. By identifying examples that are nontypical in the determination of relevant, irredundant attributes, irrelevant examples can be eliminated prior to the learning process. Empirical results using artificial and real databases show the effectiveness of the proposed method in selecting relevant examples leading to improved performance even on greatly reduced training sets.

When does power in intimate relationships shape important interpersonal behaviors, such as psychological aggression? Five studies tested whether possessing low relationship power was associated with aggressive responses, but (1) only within power-relevant relationship interactions when situational power was low, and (2) only by men because masculinity (but not femininity) involves the possession and demonstration of power. In Studies 1 and 2, men lower in relationship power exhibited greater aggressive communication during couples’ observed conflict discussions, but only when they experienced low situational power because they were unable to influence their partner. In Study 3, men lower in relationship power reported greater daily aggressive responses toward their partner, but only on days when they experienced low situational power because they were either (a) unable to influence their partner or (b) dependent on their partner for support. In Study 4, men who possessed lower relationship power exhibited greater aggressive responses during couples’ support-relevant discussions, but only when they had low situational power because they needed high levels of support. Study 5 provided evidence for the theoretical mechanism underlying men’s aggressive responses to low relationship power. Men who possessed lower relationship power felt less manly on days they faced low situational power because their partner was unwilling to change to resolve relationship problems, which in turn predicted greater aggressive responses to their partner. These results demonstrate that fully understanding when and why power is associated with interpersonal behavior requires differentiating between relationship and situational power. PMID:27442766

Epilepsy is a chronic illness that requires a long-term periodic follow-up of the patient and this means that as time goes by the number of patients attended increases, with the ensuing added cost for the healthcare system. To determine the factors involved in the time until an epileptic patient's next visit. Our sample consisted of a selection of patients who visited the epilepsy clinic at our hospital consecutively during one year. Their clinical situation and relationship with the medical advice they were given, together with the factors involved in the time elapsed until the next visit, were analysed by means of predictive econometric models. There is a clear association between the patient's clinical situation and the modification of the treatment proposed by the neurologist in the previous visit. The factors involved in the time until the next visit were the frequency of seizures, adverse side effects from medicines -above all those that affect cognition- and the medical advice given to the patient. Polytherapy, psychoaffective disorders or the patient's social situation were not found to be significant. Follow-up visits in a specific epilepsy clinic improves the patient's situation. This is the first analysis of the demand for healthcare in patients with epilepsy conducted by means of econometric methods and from a mixed physician-patient perspective. Since the factors that determine the time until the next visit can be modified, the number of visits per year could be reduced, thus improving patients' clinical situation. We suggest a greater amount of time should be spent per visit so as to be able to have a bearing on it and thereby cut costs in the long term.
Drug Information Services Today: Current Role and Future Perspectives in Rational Drug Therapy.
Amundstuen Reppe, Linda; Spigset, Olav; Schjøtt, Jan
2016-02-01
Polypharmacy and complex drug treatment regimens are becoming increasingly common, which may lead to adverse drug reactions, drug interactions, medication nonadherence, and increasing costs and thus challenge the rational use of drugs. At the same time, the accessibility of drug information increases, and health care professionals may have limited opportunities and capabilities to search and critically evaluate drug information. Clinicians have reported difficulties in searching the best evidence and translating study findings into clinically meaningful information applicable to specific patients. Consequently, it remains a challenge to ensure the rational use of drugs in the years to come. Drug information centers (DICs) have been established to promote the rational use of drugs. One of the most important tasks of DICs is the question and answer services for health care professionals posing drug-related questions. DICs staffed by pharmacists and clinical pharmacologists hold expertise in searching for drug information and critical evaluation of the literature. The uniqueness in this service lies not only in the identification and interpretation of the scientific literature but also in the adaptation of the findings into specific clinical situations and the discussion of possible solutions with the enquirer. Thus, DICs could provide valuable decision support to the clinic. Taking into account the increasing number of possible drug-related questions that will arise today and in the future, the DICs will remain highly relevant in the years to come. However, the DICs must follow the developments in health information technology to disseminate relevant, unbiased drug information to old and new users of the service. Moreover, the DICs are important tools to counterbalance the drug information published by the pharmaceutical industry. Copyright © 2016 Elsevier HS Journals, Inc. All rights reserved.

Background Population-based studies investigating indications for antidepressant prescribing mostly rely on diagnoses from general practitioners. However, diagnostic codes might be incomplete and drugs may be prescribed 'off-label' for indications not investigated in clinical trials. Objective We aimed to study indications for antidepressant use based on self-report. Also, we studied the presence of depressive symptoms associated with the self-reported indications. Setting Our study population of antidepressant users was selected based on interview data between 1997 and 2013 from the prospective population-based Rotterdam Study cohort (age >45 years). Method Antidepressant use, self-reported indication for use, and presence of depressive symptoms (Center for Epidemiological Studies Depression Scale) were based on interview. Self-reported indications were categorized by the researchers into officially approved, clinically-accepted and commonly mentioned off-label indications. Main outcome measures A score of 16 and higher on the Center for Epidemiological Studies Depression Scale was considered as indicator for clinically-relevant depressive symptoms. Results The majority of 914 antidepressant users reported 'depression' (52.4 %) as indication for treatment. Furthermore, anxiety, stress and sleep disorders were reported in selective serotonin reuptake inhibitor and other antidepressant users (ranging from 5.9 to 13.3 %). The indication 'pain' was commonly mentioned by tricyclic antidepressant users (19.0 %). Indications were statistically significantly associated with higher depressive symptom scores when compared to non-users (n = 10,979). Conclusions Depression was the main indication for antidepressant treatment. However, our findings suggest that antidepressants are also used for off-label indications, subthreshold disorders and complex situations, which were all associated with clinically-relevant depressive symptoms in the middle-aged and elderly population.

Situativity theory refers to theoretical frameworks which argue that knowledge, thinking, and learning are situated (or located) in experience. The importance of context to these theories is paramount, including the unique contribution of the environment to knowledge, thinking, and learning; indeed, they argue that knowledge, thinking, and learning cannot be separated from (they are dependent upon) context. Situativity theory includes situated cognition, situated learning, ecological psychology, and distributed cognition. In this Guide, we first outline key tenets of situativity theory and then compare situativity theory to information processing theory; we suspect that the reader may be quite familiar with the latter, which has prevailed in medical education research. Contrasting situativity theory with information processing theory also serves to highlight some unique potential contributions of situativity theory to work in medical education. Further, we discuss each of these situativity theories and then relate the theories to the clinical context. Examples and illustrations for each of the theories are used throughout. We will conclude with some potential considerations for future exploration. Some implications of situativity theory include: a new way of approaching knowledge and how experience and the environment impact knowledge, thinking, and learning; recognizing that the situativity framework can be a useful tool to "diagnose" the teaching or clinical event; the notion that increasing individual responsibility and participation in a community (i.e., increasing "belonging") is essential to learning; understanding that the teaching and clinical environment can be complex (i.e., non-linear and multi-level); recognizing that explicit attention to how participants in a group interact with each other (not only with the teacher) and how the associated learning artifacts, such as computers, can meaningfully impact learning.
Perceived Levels of Frustration During Clinical Situations in Athletic Training Students
Heinerichs, Scott; Curtis, Neil; Gardiner-Shires, Alison
2014-01-01
Context: Athletic training students (ATSs) are involved in various situations during the clinical experience that may cause them to express levels of frustration. Understanding levels of frustration in ATSs is important because frustration can affect student learning, and the clinical experience is critical to their development as professionals. Objective: To explore perceived levels of frustration in ATSs during clinical situations and to determine if those perceptions differ based on sex. Design: Cross-sectional study with a survey instrument. Setting: A total of 14 of 19 professional, undergraduate athletic training programs accredited by the Commission on Accreditation of Athletic Training Education in Pennsylvania. Patients or Other Participants: Of a possible 438 athletic training students, 318 (72.6%) completed the survey. Main Outcomes Measure(s): The Athletic Training Student Frustration Inventory was developed and administered. The survey gathered demographic information and included 24 Likert-scale items centering on situations associated with the clinical experience. Descriptive statistics were computed on all items. The Mann-Whitney U was used to evaluate differences between male and female students. Results: A higher level of frustration was perceived during the following clinical situations: lack of respect by student-athletes and coaching staffs, the demands of the clinical experience, inability of ATSs to perform or remember skills, and ATSs not having the opportunity to apply their skills daily. Higher levels of frustration were perceived in female than male ATSs in several areas. Conclusions: Understanding student frustration during clinical situations is important to better appreciate the clinical education experience. Low levels of this emotion are expected; however, when higher levels exist, learning can be affected. Whereas we cannot eliminate student frustrations, athletic training programs and preceptors need to be aware of this emotion in order to create an environment that is more conducive to learning.

Online Chat Dependency: The Influence of Social Anxiety
NASA Astrophysics Data System (ADS)
Wang, Chih-Chien; Chang, Shu-Chen
Recent developments in information technology have made it easy for people to “chat” online with others in real time, and many do so regularly. “Virtual” relationships can be attractive, especially for people with social interaction problems in the “real world”. This study examines the influence on online chat dependency of three dimensions of social anxiety: general social situation fear, negative evaluation fear, and novel social situation fear. Participants of this study were 454 college students. The survey results show that negative evaluation fear and general social situation fear are relative to online chat dependency, while novel social situation fear does not seem to be a relevant factor.
Clinical relevance in anesthesia journals.
Lauritsen, Jakob; Møller, Ann M
2006-04-01
The purpose of this review is to present the latest knowledge and research on the definition and distribution of clinically relevant articles in anesthesia journals. It will also discuss the importance of the chosen methodology and outcome of articles. In the last few years, more attention has been paid to evidence-based medicine in anesthesia. Several articles on the subject have focused on the need to base clinical decisions on sound research employing both methodological rigor and clinically relevant outcomes. The number of systematic reviews in anesthesia literature is increasing as well as the focus on diminishing the number of surrogate outcomes. It has been shown that the impact factor is not a valid measure of establishing the level of clinical relevance to a journal. This review presents definitions of clinically relevant anesthesia articles. A clinically relevant article employs both methodological rigor and a clinically relevant outcome. The terms methodological rigor and clinical outcomes are fully discussed in the review as well as problems with journal impact factors.

Early recognition and situation awareness of sudden patient deterioration, a timely appropriate clinical response, and teamwork are critical to patient outcomes. High fidelity simulated environments provide the opportunity for undergraduate nursing students to develop and refine recognition and response skills. This paper reports the quantitative findings of the first phase of a larger program of ongoing research: Feedback Incorporating Review and Simulation Techniques to Act on Clinical Trends (FIRST2ACTTM). It specifically aims to identify the characteristics that may predict primary outcome measures of clinical performance, teamwork and situation awareness in the management of deteriorating patients. Mixed-method multi-centre study. High fidelity simulated acute clinical environment in three Australian universities. A convenience sample of 97 final year nursing students enrolled in an undergraduate Bachelor of Nursing or combined Bachelor of Nursing degree were included in the study. In groups of three, participants proceeded through three phases: (i) pre-briefing and completion of a multi-choice question test, (ii) three video-recorded simulated clinical scenarios where actors substituted real patients with deteriorating conditions, and (iii) post-scenario debriefing. Clinical performance, teamwork and situation awareness were evaluated, using a validated standard checklist (OSCE), Team Emergency Assessment Measure (TEAM) score sheet and Situation Awareness Global Assessment Technique (SAGAT). A Modified Angoff technique was used to establish cut points for clinical performance. Student teams engaged in 97 simulation experiences across the three scenarios and achieved a level of clinical performance consistent with the experts' identified pass level point in only 9 (1%) of the simulation experiences. Knowledge was significantly associated with overall teamwork (p=.034), overall situation awareness (p=.05) and clinical performance in two of the three scenarios (p=.032 cardiac and p=.006 shock). Situation awareness scores of scenario team leaders were low overall, with an average total score of 41%. Final year undergraduate nursing students may have difficulty recognising and responding appropriately to patient deterioration. Improving pre-requisite knowledge, rehearsal of first response and team management strategies need to be a key component of undergraduate nursing students' education and ought to specifically address clinical performance, teamwork and situation awareness. © 2013 Elsevier Ltd.

This study presents the validation of the French Canadian version (PACLSAC-F) of the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC). Unlike the published validation of the English version of the PACSLAC, which was validated retrospectively, the French version was validated prospectively. The PACSLAC-F was completed by nurses working in long-term care facilities after observing 86 seniors, with severe cognitive impairment, in calm, painful or distressing but non-painful situations. The test-retest and inter-observer reliability, the internal consistency, and the discriminent validity were found to be satisfactory. To evaluate the convergent validity with the DOLOPLUS-2 and the clinical relevance of the PACSLAC, it was also completed by nurses during their work shift, with 26 additional patients, for three days per week during a period of four weeks. These results encourage us to test the PACSLAC in a comprehensive program of pain management targeting this population.
Biomarker-guided antibiotic therapy—strengths and limitations
Salluh, Jorge; Martin-Loeches, Ignacio; Póvoa, Pedro
2017-01-01
Biomarkers as C-reactive protein (CRP) and procalcitonin (PCT) emerged as tools to help clinicians to diagnose infection and to properly initiate and define the duration of antibiotic therapy. Several randomized controlled trials, including adult critically ill patients, showed that PCT-guided antibiotic stewardship was repeatedly associated with a decrease in the duration of antibiotic therapy with no apparent harm. There are however some relevant limitations in these trials namely the low rate of compliance of PCT-guided algorithms, the high rate of exclusion (without including common clinical situations and pathogens) and the long duration of antibiotic therapy in control groups. Such limitations weakened the real impact of such algorithms in the clinical decision-making process and strengthened the concept that the initiation and the duration of antibiotic therapy cannot depend solely on a biomarker. Future efforts should address these limitations in order to better clarify the role of biomarkers on the complex and multifactorial issue of antibiotic management and to deeply understand its potential effect on mortality.

Social Anxiety and Heavy Situational Drinking: Coping and Conformity Motives as Multiple Mediators
Terlecki, Meredith A.; Buckner, Julia D.
2014-01-01
Individuals with clinically elevated social anxiety are at greater risk for alcohol use disorder, and the relation between social anxiety and drinking problems is at least partially accounted for by drinking more in negative emotional (e.g., feeling sad or angry) and personal/intimate (e.g., before sexual intercourse) situations. Identification of cognitive/motivational factors related to drinking in these high-risk situations could inform the development of treatment and prevention interventions for these high-risk drinkers. The current study examined the mediating effect of drinking motives on the relationship between social anxiety and drinking these high-risk situations amongst undergraduates (N = 232). Clinically elevated social anxiety was associated with greater coping and conformity motives. Both coping and conformity motives mediated the relation between social anxiety and heavier alcohol consumption in negative emotional and personal/intimate contexts. Multiple mediation analyses indicated that these motives work additively to mediate the social anxiety-drinking situations relationship, such that that heavy situational drinking amongst undergraduates with clinically elevated social anxiety can be jointly attributed to desire to cope with negative affect and to avoid social scrutiny.

Can eye-tracking technology improve situational awareness in paramedic clinical education?
Williams, Brett; Quested, Andrew; Cooper, Simon
2013-01-01
Human factors play a significant part in clinical error. Situational awareness (SA) means being aware of one's surroundings, comprehending the present situation, and being able to predict outcomes. It is a key human skill that, when properly applied, is associated with reducing medical error: eye-tracking technology can be used to provide an objective and qualitative measure of the initial perception component of SA. Feedback from eye-tracking technology can be used to improve the understanding and teaching of SA in clinical contexts, and consequently, has potential for reducing clinician error and the concomitant adverse events.
The situation specificity of youth responses to peer provocation.
Dirks, Melanie A; Treat, Teresa A; Weersing, V Robin
2007-01-01
Previous studies have identified peer provocation as a challenging class of situations for youth. The work presented here builds on previous methods of assessing peer provocation by (a) increasing the contextual detail of the vignettes; (b) developing a reliable, descriptive coding system of the range of youth responses to physical, verbal, and relational provocation; and (c) assessing the relevance of these situations for a sample (N = 76) of ethnically diverse, economically disadvantaged youth ages 12 to 14. The vignettes were used to examine the situation specificity of youth responses to provocation. Situation and identity of aggressor were both predictors of youth responses. For example, participants "matched" physical aggression to physical provocation. These findings are consistent with previous studies demonstrating the situation specificity of social information processing, even within the relatively homogeneous category of peer provocations.
Flowable Resin Composites: A Systematic Review and Clinical Considerations
Rodrigues, Jean C.
2015-01-01
Background Little is known about flowable composite materials. Most literature mentions conventional composite materials at large, giving minimal emphasis to flowables in particular. This paper briefly gives an in depth insight to the multiple facets of this versatile material. Aim To exclusively review the most salient features of flowable composite materials in comparison to conventional composites and to give clinicians a detailed understanding of the advantages, drawbacks, indications and contraindications based on composition and physical/mechanical properties. Methodology Data Sources: A thorough literature search from the year 1996 up to January 2015 was done on PubMed Central, The Cochrane Library, Science Direct, Wiley Online Library, and Google Scholar. Grey literature (pending patents, technical reports etc.) was also screened. The search terms used were “dental flowable resin composites”. Search Strategy After omitting the duplicates/repetitions, a total of 491 full text articles were assessed. As including all articles were out of the scope of this paper. Only relevant articles that fulfilled the reviewer’s objectives {mentioning indications, contraindications, applications, assessment of physical/mechanical/biological properties (in vitro/ in vivo /ex vivo)} were considered. A total of 92 full text articles were selected. Conclusion Flowable composites exhibit a variable composition and consequently variable mechanical/ physical properties. Clinicians must be aware of this aspect to make a proper material selection based on specific properties and indications of each material relevant to a particular clinical situation. PMID:26266238

What does the amygdala contribute to social cognition?
Adolphs, Ralph
2010-01-01
The amygdala has received intense recent attention from neuroscientists investigating its function at the molecular, cellular, systems, cognitive, and clinical level. It clearly contributes to processing emotionally and socially relevant information, yet a unifying description and computational account have been lacking. The difficulty of tying together the various studies stems in part from the sheer diversity of approaches and species studied, in part from the amygdala’s inherent heterogeneity in terms of its component nuclei, and in part because different investigators have simply been interested in different topics. Yet, a synthesis now seems close at hand in combining new results from social neuroscience with data from neuroeconomics and reward learning. The amygdala processes a psychological stimulus dimension related to saliency or relevance; mechanisms have been identified to link it to processing unpredictability; and insights from reward learning have situated it within a network of structures that include the prefrontal cortex and the ventral striatum in processing the current value of stimuli. These aspects help to clarify the amygdala’s contributions to recognizing emotion from faces, to social behavior toward conspecifics, and to reward learning and instrumental behavior. PMID:20392275

The implicit use of overarching osteopathic principles (OP) in clinical practice is a regulatory requirement; agreed definition of what constitutes such principles remains elusive. The profession currently faces questions of identity and relevance in the face of evidence-informed healthcare. This study sought to investigate the opinions and experiences of practising osteopathic educators as to how OP are relevant to clinical practice in isolation and to the profession as a whole. A qualitative approach employing grounded theory to explore the views of current practitioners involved in osteopathic education. Nine practising osteopaths were selected for the study using initially purposive then theoretical sampling. Semi-structured interviews were used to gather data, audio-recorded, transcribed verbatim and anonymised. Data was analysed and interpreted using a thematic framework approach and conceptually modelled. Triangulation was completed; peer corroboration for high-level themes and participant confirmation for transcript authenticity was obtained. Two polarised concepts emerged: (1) OP benefit the profession and (2) OP limit or jeopardize the profession. These emanated from different perceptions of the identity of osteopathy: (1) osteopathy as a philosophy or (2) osteopathy as a manual therapy with a philosophical background. The osteopathic profession faces the danger of being divided on the basis of ideological differences from within. The increasing criticality applied to UK healthcare behoves the osteopathic profession to clarify its aims, guiding 'principles' and underlying values. This could be problematic in light of the divergence of views, leading to a situation of either settling these differences or irrevocably fracturing the profession. Copyright © 2015 Elsevier Ltd.

Publications in anesthesia journals: quality and clinical relevance.
Lauritsen, Jakob; Moller, Ann M
2004-11-01
Clinicians performing evidence-based anesthesia rely on anesthesia journals for clinically relevant information. The objective of this study was to analyze the proportion of clinically relevant articles in five high impact anesthesia journals. We evaluated all articles published in Anesthesiology, Anesthesia & Analgesia, British Journal of Anesthesia, Anesthesia, and Acta Anaesthesiologica Scandinavica from January to June, 2000. Articles were assessed and classified according to type, outcome, and design; 1379 articles consisting of 5468 pages were evaluated and categorized. The most common types of article were animal and laboratory research (31.2%) and randomized clinical trial (20.4%). A clinically relevant article was defined as an article that used a statistically valid method and had a clinically relevant end-point. Altogether 18.6% of the pages had as their subject matter clinically relevant trials. We compared the Journal Impact Factor (a measure of the number of citations per article in a journal) and the proportion of clinically relevant pages and found that they were inversely proportional to each other.

Today’s international nuclear safeguards inspectors have access to an increasing volume of supplemental information about the facilities under their purview, including commercial satellite imagery, nuclear trade data, open source information, and results from previous safeguards activities. In addition to completing traditional in-field safeguards activities, inspectors are now responsible for being able to act upon this growing corpus of supplemental safeguards-relevant data and for maintaining situational awareness of unusual activities taking place in their environment. However, cognitive science research suggests that maintaining too much information can be detrimental to a user’s understanding, and externalizing information (for example, to a mobile device)more » to reduce cognitive burden can decrease cognitive function related to memory, navigation, and attention.

Familial risks of breast and prostate cancers: does the definition of the at risk period matter?
Brandt, Andreas; Bermejo, Justo Lorenzo; Sundquist, Jan; Hemminki, Kari
2010-03-01
'Being at familial risk' may have different connotations in studies on familial risk of cancer. The register-based definition of a family history considers individuals with an affected relative at familial risk independently of the family member's diagnostic time. Alternatively, the individuals are classified to be at familial risk only after the diagnosis date of their relative, relevant to clinical counselling and screening situations. The aim of this study was to compare familial breast and prostate cancer risks according to the two definitions. The nationwide Swedish Family-Cancer Database with information on cancers from 1958 to 2006 was used to calculate the hazard ratio of breast and prostate cancers according to family history using Cox regression. Family history was defined considering the number and type of affected relatives and the relative's diagnostic age, respectively. Individuals were considered at familial risk from their entry to the study or, alternatively, from the diagnostic time of the relative. Hazard ratios were equal whether individuals were considered at risk independent of the relative's diagnostic date or only after the relative's diagnostic date. These results indicate that studies on familial breast or prostate cancer risk which do not take the relative's diagnosis date into account are applicable to screening and clinical counselling situations. The estimates according to the register-based definition are based on larger numbers of patients, which may be crucial for analysis of small groups such as families of multiple cases.

For a multitude of eminently modifiable reasons, death rates for pregnant women and girls and their newborn infants in poorly resourced countries remain unacceptably high. The concomitant high morbidity rates compound the situation. The rights of these vulnerable individuals are incompletely protected by existing United Nations human rights conventions, which many countries have failed to implement. The authors propose a novel approach grounded on both human rights and robust evidence-based clinical guidelines to create a 'human rights convention specifically for pregnant women and girls and their newborn infants'. The approach targets the 'right to health' of these large, vulnerable and neglected populations. The proposed convention is designed so that it can be monitored, audited and evaluated objectively. It should also foster a sense of national ownership and accountability as it is designed to be relevant to local situations and to be incorporated into local clinical governance systems. It may be of particular value to those countries that are not yet on target to meet the Millennium Development Goals (MDGs), especially MDGs 4 and 5, which target child and maternal mortality, respectively. To foster a sense of international responsibility, two additional initiatives are integral to its philosophy: the promotion of twinning between well and poorly resourced regions and a raising of awareness of how some well-resourced countries can damage the health of mothers and babies, for example, through the recruitment of health workers trained by national governments and taken from the public health system.

An inventory on the two critical dimensions that structure the Randomized Controlled Trial in Psychiatry, namely the definition of inclusion criteria for eligible patients for testing and the choice of psychometric methods of pathology assessment and its evolution during the experiment, considers the importance of increasingly numerous and precise international recommendations. Taking into account the formal constraints of industrial, questioning the cultural differences of the methodological approach of the tests, meeting the requirements of feasibility and ever increasing security, frequent cumbersome procedure often contrasts with the modest nature of the results. A better definition to include patients in randomized trials is desirable and it asks to return to the clinic studying the expectations of patients and their response to the therapeutic situation. Excessive standardization otherwise required for ensuring the objective nature of the assessment hampers the collection of original and varied clinical features of importance in the further definitions of indications. On the way to a resumption of the single case study, we can expect from qualitative methods applied to small groups of subjects, optimization principles of patient selection for the upcoming randomized trial and greater chance to address the relevant details of clinical response to the therapeutic situation. This is what has led to the discovery of psychotropic drugs and which is involved in the various modalities of the qualitative approach. For example, and beyond the exploration of clinical drug effects, the study of the experience of psychiatric inpatient care in the Healing Garden, conducted on a small group and on the basis of the narrative analysis of their experience, notes several operating thematic dimensions: a reduction in the perception of symptoms of the disease, the impression of regaining a foothold into reality, the interest of a differently perceived doctor-patient relationship, the advantage of renewed power to act and the recognition of the importance of support from others, patients recovering somehow « vitality » of touch with reality. This suggests the possibility to establish an appropriate rating scale for such a specific therapeutic situation and to provide a more accurate and efficient recruitment for a comparative objective demonstration. Moreover, this construction of meaning reinforces the therapeutic benefit of treatment in Healing Garden and offers new dimensions for research. © L’Encéphale, Paris, 2016.
Context as Relevance-Driven Abduction and Charitable Satisficing
Attardo, Salvatore
2016-01-01
It has been widely assumed that the full meaning of a linguistic expression can be grasped only within a situation, the context of the utterance. There is even agreement that certain factors within the situation are particularly significant, including gestures and facial expressions of the participants, their social roles, the setting of the exchange, the objects surrounding the participants, the linguistic, cultural and educational backgrounds of the participants, their beliefs, including those concerning the situation, the social procedures and conventions that regulate the situation. Finally, there is some agreement that context is dynamic, reflexive (the speakers are mutually aware of their beliefs), not limited to linguistics actions, and last but not least, a psychological construct. This definition of context is not (very) controversial, but it leaves out two major problems, which will be addressed in this paper: how is context arrived at? And, since a perfectly natural interpretation of the above definition could be that the context of each utterance is the entire universe, how is the relevant context delimited? Four related concepts will provide the answer to both questions: abductive reasoning, driven by relevance and cooperation, and bounded rationality and the principle of charity. Simply put, context is derived abductively by the speakers assuming that for the speakers to behave the way they behave and do so rationally, a given context must be available to them. The context is bounded by the simple requirement that speakers not try to optimize their interpretation/calculation, but rather satisfice, i.e., find the first acceptable solution and by the need to follow the principle of charity, which forces intersubjective agreement. Thus, abductive reasoning and bounded rationality will be shown to be sufficient to calculate the relevant context of utterances (or other rationality-driven interactions) and to effectively delimit the potentially infinite search space that must be explored to do so.

[Disease versus disorder. Medical and socio-environmental aspects of mental suffering].
Heinz, A
2015-01-01
A disease concept should be broad enough to provide social protection for all subjects suffering from this malady but at the same time it needs to be narrow enough to avoid pathologization of behavior that is merely socially undesirable. From a medical perspective a"disease" is present if functions are impaired that are relevant for individual survival. In the field of psychiatry and psychotherapy, such medically relevant functions include the ability to be alert and fully oriented, to ascribe one's own intentions to oneself and to modulate affects according to the situation. Beyond such medically relevant symptoms of a disease, any clinically relevant dysfunction should also be harmful for the individual if a mental malady is to be diagnosed. One such harmful consequence of a disease can be that the person feels ill and suffers from this state, another negative consequence for the individual can be due to an impairment of activities of daily living and social participation. These harmful consequences of a disease are usually discussed under the heading of the"illness experience" and the"sickness aspect" of any disorder. Beyond mental maladies characterized by disease symptoms that are accompanied either by an illness experience or impaired activities of daily living and social participation (sickness), there are many states of human suffering which can be objectified and classified but do not constitute a disease in the medical sense and should more aptly be named a disorder.

A previous definition of adolescent asthma self-management was derived from interviews with clinicians/researchers and published literature; however, it did not incorporate perspectives of teens or parents. Therefore, we conducted in-depth interviews with teens and parents and synthesized present findings with the prior analysis to develop a more encompassing definition and model. Focal concepts were qualitatively extracted from 14-day self-management voice-diaries (n = 14) and 1-hour interviews (n = 42) with teens and parents (28 individuals) along with concepts found in the previous clinical/research oriented analysis. Conceptual structure and relationships were identified and key findings synthesized to develop a revised definition and model of adolescent asthma self-management. There were two primary self-management constructs: processes of self-management and tasks of self-management. Self-management was defined as the iterative process of assessing, deciding, and responding to specific situations in order to achieve personally important outcomes. Clinically relevant asthma self-management tasks included monitoring asthma, managing active issues through pharmacologic and non-pharmacologic strategies, preventing future issues, and communicating with others as needed. Self-management processes were reciprocally influenced by intrapersonal factors (both cognitive and physical), interpersonal factors (family, social and physical environments), and personally relevant asthma and non-asthma outcomes. This is the first definition of asthma self-management incorporating teen, parent, clinician, and researcher perspectives, which suggests that self-management processes and behaviors are influenced by individually variable personal and interpersonal factors, and are driven by personally important outcomes. Clinicians and researchers should investigate teens' symptom perceptions, medication beliefs, current approaches to symptom management, relevant outcomes, and personal priorities.

Clinical practice guidelines play an important role in reducing the variations in clinical practices and improving the quality of care. To assess the real effect, measuring its implementation situation is needed. The implementation situation can be reflected by testing the consistency between the actual clinical practice and the guideline. We constructed an instrument to measure the implementation situation of Traditional Chinese Medicine (TCM) guideline through consistency testing. The main objectives of our study were to validate the instrument and evaluate the implementation situation of menopause syndrome guideline of TCM, using the data from the consistency test of comparing the medical records with the guideline. A total of 621 cases were included for data analysis. Cronbach's Alpha coefficient is 0.73. The model fit of 7 items in four dimensions was good (SRMR = 0.04; GFI = 0.97; NFI = 0.97; TLI = 0.96; CFI = 0.98; AGFI = 0.90). This instrument is of good reliability and validity. It can help the guideline developers to measure the implementation situation, find the reasons affecting the implementation, and revise the guideline. The method of using consistency test to measure the implementation situation may provide a sample for evaluating the guideline implementation in other fields. PMID:29234379
Use of heat-pressed leucite reinforced porcelain in "difficult" veneer cases: a clinical report.
Rouse, J S
1996-11-01
Two clinical situations are presented where a heat-pressed leucite reinforced ceramic veneer system was used. For these situations the system was advantageous when veneers (1) required bulk or variable thicknesses or (2) were under load from function and parafunctional activity. This porcelain veneer system addressed some of the concerns associated with standard feldspathic porcelain and castglass systems. Practitioners should consider its use for situations that require a stronger veneer material.
The role of blended learning in the clinical education of healthcare students: a systematic review.
Rowe, Michael; Frantz, Jose; Bozalek, Vivienne
2012-01-01
Developing practice knowledge in healthcare is a complex process that is difficult to teach. Clinical education exposes students to authentic learning situations, but students also need epistemological access to tacit knowledge and clinical reasoning skills in order to interpret clinical problems. Blended learning offers opportunities for the complexity of learning by integrating face-to-face and online interaction. However, little is known about its use in clinical education. To determine the impact of blended learning in the clinical education of healthcare students. Articles published between 2000 and 2010 were retrieved from online and print sources, and included multiple search methodologies. Search terms were derived following a preliminary review of relevant literature. A total of 71 articles were retrieved and 57 were removed after two rounds of analysis. Further methodological appraisals excluded another seven, leaving seven for the review. All studies reviewed evaluated the use of a blended learning intervention in a clinical context, although each intervention was different. Three studies included a control group, and two were qualitative in nature. Blended learning was shown to help bridge the gap between theory and practice and to improve a range of selected clinical competencies among students. Few high-quality studies were found to evaluate the role of blended learning in clinical education, and those that were found provide only rudimentary evidence that integrating technology-enhanced teaching with traditional approaches have potential to improve clinical competencies among health students. Further well-designed research into the use of blended learning in clinical education is therefore needed before we rush to adopt it.

The aim of this study was to test the validity of a computer software program previously demonstrated to be capable of making DSM-IV neuropsychiatric diagnoses from the content analysis of speech or verbal texts. In this report, the computer program was applied to three personal writings of Napoleon Bonaparte when he was 12 to 16 years of age. The accuracy of the neuropsychiatric evaluations derived from the computerized content analysis of these writings of Napoleon was independently corroborated by two biographers who have described pertinent details concerning his life situations, moods, and other emotional reactions during this adolescent period of his life. The relevance of this type of computer technology to psychohistorical research and clinical psychiatry is suggested.
Quality of HbA1c Measurement in the Practice
Freckmann, Guido
2015-01-01
Hemoglobin A1c (HbA1c) measurement has come to be a cornerstone in modern diabetes therapy. However, the methodological aspects of this type of measurement have been given little attention lately due to its position as an established method of choice. Nevertheless, quite a number of issues face practical application, such as clinically relevant differences between different measurement methods—both lab-based and point-of-care (POCT) systems will show better or worse diabetes management results after switching methods; and there are a number of possible reasons that need to be known and observed in practice. The aim of this review is to draw attention to these problems from a German point of view and provide suggestions for appropriate measures to improve the situation. PMID:25691655

Ethical case deliberation on the ward. A comparison of four methods.
Steinkamp, Norbert; Gordijn, Bert
2003-01-01
The objective of this article is to analyse and compare four methods of ethical case deliberation. These include Clinical Pragmatism, The Nijmegen Method of ethical case deliberation, Hermeneutic dialogue, and Socratic dialogue. The origin of each method will be briefly sketched. Furthermore, the methods as well as the related protocols will be presented. Each method will then be evaluated against the background of those situations in which it is being used. The article aims to show that there is not one ideal method of ethical case deliberation, which fits to all possible kinds of moral problems. Rather, as each of the methods highlights a limited number of morally relevant aspects, each method has its strengths and weaknesses as well. These strengths and weaknesses should be evaluated in relation to different types of situations, for instance moral problems in treatment decisions, moral uneasiness and residue, and the like. The suggestion arrived at on the basis of the findings of this paper is a reasonable methodological plurality. This means that a method can be chosen depending on the type of moral problem to be deliberated upon. At the same time it means, that by means of a method, deliberation should be facilitated.

Background Disagreement among healthcare professionals on the clinical relevance of drug-related problems can lead to suboptimal treatment and increased healthcare costs. Elderly patients with chronic non-cancer pain and comorbidity are at increased risk of drug related problems compared to other patient groups due to complex medication regimes and transition of care. Objective To investigate the agreement among healthcare professionals on their classification of clinical relevance of drug-related problems in elderly patients with chronic non-cancer pain and comorbidity. Setting Multidisciplinary Pain Centre, Rigshospitalet, Copenhagen, Denmark. Method A pharmacist performed medication review on elderly patients with chronic non-cancer pain and comorbidity, identified their drug-related problems and classified these problems in accordance with an existing categorization system. A five-member clinical panel rated the drug-related problems' clinical relevance in accordance with a five-level rating scale, and their agreement was compared using Fleiss' κ. Main outcome measure Healthcare professionals' agreement on clinical relevance of drug related problems, using Fleiss' κ. Results Thirty patients were included in the study. A total of 162 drug related problems were identified, out of which 54% were of lower clinical relevance (level 0-2) and 46% of higher clinical relevance (level 3-4). Only slight agreement (κ = 0.12) was found between the panellists' classifications of clinical relevance using a five-level rating scale. Conclusion The clinical pharmacist identified drug related problems of lower and higher clinical relevance.

Terlecki, Meredith A; Buckner, Julia D
2015-01-01
Individuals with clinically elevated social anxiety are at greater risk for alcohol use disorder, and the relation between social anxiety and drinking problems is at least partially accounted for by drinking more in negative emotional (e.g., feeling sad or angry) and personal/intimate (e.g., before sexual intercourse) situations. Identification of cognitive/motivational factors related to drinking in these high-risk situations could inform the development of treatment and prevention interventions for these high-risk drinkers. The current cross-sectional study examined the mediating effect of drinking motives on the relationship between social anxiety and drinking these high-risk situations among undergraduates (N=232). Clinically elevated social anxiety was associated with greater coping and conformity motives. Both coping and conformity motives mediated the relation between social anxiety and heavier alcohol consumption in negative emotional and personal/intimate contexts. Multiple mediation analyses indicated that these motives work additively to mediate the social anxiety-drinking situations relationship, such that heavy situational drinking among undergraduates with clinically elevated social anxiety can be jointly attributed to desire to cope with negative affect and to avoid social scrutiny.

Background Variability in patients' postoperative pain experience and response to treatment challenges effective pain management. Variability in pain reflects individual differences in inhibitory pain modulation and psychological sensitivity, which in turn may be clinically relevant for the disposition to acquire pain. The aim of this study was to investigate the effects of conditioned pain modulation and situational pain catastrophizing on postoperative pain and pain persistency. Methods Preoperatively, 42 healthy males undergoing funnel chest surgery completed the Spielberger's State-Trait Anxiety Inventory and Beck's Depression Inventory before undergoing a sequential conditioned pain modulation paradigm. Subsequently, the Pain Catastrophizing Scale was introduced and patients were instructed to reference the conditioning pain while answering. Ratings of movement-evoked pain and consumption of morphine equivalents were obtained during postoperative days 2–5. Pain was reevaluated at six months postoperatively. Results Patients reporting persistent pain at six months follow-up (n = 15) were not significantly different from pain-free patients (n = 16) concerning preoperative conditioned pain modulation response (Z = 1.0, P = 0.3) or level of catastrophizing (Z = 0.4, P = 1.0). In the acute postoperative phase, situational pain catastrophizing predicted movement-evoked pain, independently of anxiety and depression (β = 1.0, P = 0.007) whereas conditioned pain modulation predicted morphine consumption (β = −0.005, P = 0.001). Conclusions Preoperative conditioned pain modulation and situational pain catastrophizing were not associated with the development of persistent postoperative pain following funnel chest repair. Secondary outcome analyses indicated that conditioned pain modulation predicted morphine consumption and situational pain catastrophizing predicted movement-evoked pain intensity in the acute postoperative phase. These findings may have important implications for developing strategies to treat or prevent acute postoperative pain in selected patients. Pain may be predicted and the malfunctioning pain inhibition mechanism as tested with CPM may be treated with suitable drugs augmenting descending inhibition. PMID:24587268

Dealing with emotions is critical for medical trainees' professional development. Taking a sociocultural and narrative approach to understanding emotions, we studied complex clinical situations as a specific context in which emotions are evoked and influenced by the social environment. We sought to understand how medical trainees respond to emotions that arise in those situations. In an international constructivist grounded theory study, 29 trainees drew two rich pictures of complex clinical situations, one exciting and one frustrating. Rich pictures are visual representations that capture participants' perceptions about the people, situations and factors that create clinical complexity. These pictures were used to guide semi-structured, individual interviews. We analysed visual materials and interviews in an integrated way, starting with looking at the drawings, doing a 'gallery walk', and using the interviews to inform the aesthetic analysis. Participants' drawings depicted a range of personal emotions in response to complexity, and disclosed unsettling feelings and behaviours that might be considered unprofessional. When trainees felt confident, they were actively participating, engaged in creative problem-solving strategies, and emphasised their personal involvement. When trainees felt the situation was beyond their control, they described how they were running away from the situation, hiding themselves behind others or distancing themselves from patients or families. A sense of control seems to be a key factor influencing trainees' emotional and behavioural responses to complexity. This is problematic, as complex situations are by their nature emergent and dynamic, which limits possibilities for control. Following a social performative approach to emotions, we should help students understand that feeling out of control is an inherent property of participating in complex clinical situations, and, by extension, that it is not something they will 'grow out of' with expertise. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Trait and cultural psychology perspectives on the cross-situational consistency of behavior, and the predictive validity of traits, were tested in a daily process study in the United States (N = 68), an individualistic culture, and the Philippines (N = 80), a collectivistic culture. Participants completed the Revised NEO Personality Inventory (Costa & McCrae, 1992) and a measure of self-monitoring, then reported their daily behaviors and associated situational contexts for approximately 30 days. Consistent with trait perspectives, the Big Five traits predicted daily behaviors in both cultures, and relative (interindividual) consistency was observed across many, although not all, situational contexts. The frequency of various Big Five behaviors varied across relevant situational contexts in both cultures and, consistent with cultural psychology perspectives, there was a tendency for Filipinos to exhibit greater situational variability than Americans. Self-monitoring showed some ability to account for individual differences in situational variability in the American sample, but not the Filipino sample. PMID:22146866
[Pain and treatment, clinical situations and lines of questioning].
Malaquin-Pavan, Evelyne

The pain provoked by a treatment is difficult to understand by professionals, individually or collectively. Guilt, a feeling of powerlessness or doubt can arise with the healthcare worker who witnesses it or performs the treatment, and lead him/her to avoid talking about it, once the treatment is carried out. The study of clinical situations aims to incite reflection among teams to improve understanding of the complexity of these situations, influenced by the representations, perceptions and emotions of everyone involved.

Methods are needed for assessing clinicians' cultural knowledge frameworks. We used a mail survey containing four short clinical vignettes to explore respondents' ability to identify sociocultural factors affecting health and health care. Participants included 299 physicians working at the University Hospitals of Geneva, 156 private physicians, and all 134 local medical students in their clinical years. Twenty-one sociocultural "domains" were identified through inductive coding of responses. For each vignette, we obtained the sum of codes as a measure of the respondent's awareness of sociocultural factors that might affect care in this particular situation. As internal consistency was reasonably high (0.68), we computed a single total score as the sum of responses given to all four vignettes. Reponses correlated with factors that might be expected to impact clinicians' awareness of sociocultural factors affecting care. Medical students, females, respondents who had received cultural competence training, those with greater interest in caring for immigrant patients, and those with high self-assessed skills at exploring psychosocial and migration-related issues scored higher on the vignettes. Brief clinical vignettes appear to be a relevant and feasible method for exploring physicians' knowledge of social and cultural factors affecting health and health care.

Background: Undetected and unaddressed anxiety negatively affects performance in clinical learning environments. Aim: The aim was to investigate the anxiety provoking situations in clinical dental care delivery among students of preclinical and clinical years and house officers. Subjects and Methods: A 38-item modified Moss and McManus clinical anxiety questionnaire, general health questionnaire-12 (GHQ-12) and the Zung self-rating anxiety scale were the data collection tools. Results: Of the 84 recruited, 79 completed the study giving 94.0% (79/84) response rate. The median age of the participants was 25 years with 50.6% (40/79) being 20-25 years. Gender distribution revealed that males constituted 60.8% (48/79) of the participants. House officers constituted 29.1% (23/79), clinical students 36.7% (29/79), and preclinical students 34.2 (27/79) of the participants. The top anxiety provoking situations using the modified Moss and McManus clinical anxiety questionnaire were extracting wrong tooth 3.24 (1.06), inability to pass examination 3.32 (1.01), achieving examination requirement 3.19 (1.01), fracturing a tooth 3.08 (0.98) and accidental pulp exposure 2.96 (1.04). Getting diagnosis wrong, help in faint episode, not developing radiograph properly and coping with children were the anxiety provoking situations that showed statistically significant difference in the 3 studied training stages of dentistry. Bonferroni post-hoc analysis significant difference was in the preclinical and clinical students’ pair for getting diagnosis wrong, not developing radiograph properly and coping with children while house officers/clinical students and house officers/preclinical students’ pairs were for help in faint episode. Overall, 2.5% (2/79) had severe, 69.6% (55/79) moderate, 26.6% (21/79) mild clinical anxiety while 1 (1.3%) of the participants expressed no clinical anxiety. Conclusion: Data from this study revealed that the clinical anxiety of moderate severity was prevalent among the studied dental healthcare students. The anxiety-provoking situations were also found to be majorly similar in preclinical, clinical and post-graduation clinical stages of dental training stages in Nigeria. PMID:25506478

Multislice computed tomography (MSCT) has emerged as the mainstay in patients planned for transcatheter aortic valve implantation (TAVI). Incidental findings (IF) in MSCT are common. However, the exact incidence, clinical relevance and further consequences of IF are unclear and it is controversial whether IF adversely affect patients' outcome. We analyzed MSCT data of 1050 patients screened for TAVI between January 2011 and December 2014. Median follow-up of patients was 20 months. In total, 3194 IF were identified, which were classified into clinically non-relevant IF (2872, 90%) and clinically relevant IF (322, 10%). In 25% of patients (258/1050) at least one clinically relevant IF was present. Age (80 ± 7 vs. 80 ± 7 years; p = 0.198) and EuroSCORE II (3.6% [2.1-5.7] vs. 3.6% [2.1-5.9]; p = 0.874) was similar between patients with and without a clinically relevant IF. TAVI was performed less frequently in patients with a clinically relevant IF (76% vs. 85%; p < 0.001), with more patients receiving surgical aortic valve replacement in that group (14% vs. 11%; p = 0.042), possibly due to the high rate of incidental aneurysms of the ascending aorta (n = 48). If TAVI was performed mortality did not differ (30-days: 4% vs. 3%; p = 0.339, 1-year: 11% vs. 14%; p = 0.226) between patients with and without a clinically relevant IF. Our study is the largest study to analyze prevalence, clinical relevance and therapeutic consequences of IF during screening for TAVI. IF in pre-procedural MSCT are common and clinically relevant in one-quarter of patients. However, these findings had no impact on overall mortality.

Objectives To explore what it means for patients to live with chronic obstructive pulmonary disease (COPD) as an incurable and constantly progressing disease. Design Qualitative longitudinal study using narrative and semistructured interviews. This paper presents findings of the initial interviews. Analysis using grounded theory. Setting Lung care clinics and community care in Lower Saxony, Germany. Participants 17 patients with advanced-stage COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) III/IV). Findings Analysis shows that these patients have difficulties accepting their life situation and feel at the mercy of the disease, which could be identified as a core-experienced phenomenon. Over a long period of time, patients have only a vague feeling of being ill, caused by uncertain knowledge, slow progress and doubtful attribution of clinical symptoms of the disease (causal conditions). As an action strategy, patients try to maintain daily routines for as long as possible after diagnosis. Both effective standard and rescue medication, which helps to reduce breathlessness and other symptoms, and the feeling of being faced with one's own responsibility (intervening conditions) support this strategy, whereby patients' own responsibility is too painful to acknowledge. As a consequence, patients try to deny the threat to life for a long period of time. Frequently, they need to experience facing their own limits, often in the form of an acute crisis, to realise their health situation. The experience of the illness is contextualised by a continuous increase in limited mobility and social isolation. Conclusion In order to help patients to improve disease awareness, to accept their life situation and to improve their reduced quality of life, patients may benefit from the early integration of palliative care (PC), considering its multiprofessional patient-centred and team-centred approach. Psychological support and volunteer work, which are relevant aspects of PC, should be appropriate to address psychosocial needs. More research is needed to evaluate how patients could benefit from early PC. PMID:27932338

Telephone talk between clinicians represents a substantial workplace activity in postgraduate clinical education, yet junior doctors receive little training in goal-directed, professional telephone communication. To assess educational needs for telephone talk and develop a simulation-based educational intervention. Thematic analysis of 17 semi-structured interviews with doctors-in-training from various training levels and specialties. We identified essential elements to incorporate into simulation-based telephone talk, including common challenging situations for junior doctors as well as explicit and informal aspects that promote learning. These elements have implications for both junior doctors and clinical supervisors, including: (a) explicit teaching and feedback practices and (b) informal conversational interruptions and questions. The latter serve as "disguised" feedback, which aligns with recent conceptualizations of feedback as "performance relevant information". In addition to preparing clinical supervisors to support learning through telephone talk, we propose several potential educational strategies: (a) embedding telephone communication skills throughout simulation activities and (b) developing stand-alone curricular elements to sensitize junior doctors to "disguised" feedback during telephone talk as a mechanism to augment future workplace learning, i.e. 'learning how to learn' through simulation.
Beyond Googling: The Ethics of Using Patients' Electronic Footprints in Psychiatric Practice.
Fisher, Carl E; Appelbaum, Paul S
Electronic communications are an increasingly important part of people's lives, and much information is accessible through such means. Anecdotal clinical reports indicate that mental health professionals are beginning to use information from their patients' electronic activities in treatment and that their data-gathering practices have gone far beyond simply searching for patients online. Both academic and private sector researchers are developing mental health applications to collect patient information for clinical purposes. Professional societies and commentators have provided minimal guidance, however, about best practices for obtaining or using information from electronic communications or other online activities. This article reviews the clinical and ethical issues regarding use of patients' electronic activities, primarily focusing on situations in which patients share information with clinicians voluntarily. We discuss the potential uses of mental health patients' electronic footprints for therapeutic purposes, and consider both the potential benefits and the drawbacks and risks. Whether clinicians decide to use such information in treating any particular patient-and if so, the nature and scope of its use-requires case-by-case analysis. But it is reasonable to assume that clinicians, depending on their circumstances and goals, will encounter circumstances in which patients' electronic activities will be relevant to, and useful in, treatment.
[Exploration of Recent Mobile Technologies Applied in Nursing Education].
Wu, Ting-Ting; Lu, Yi-Chen; Chang, Lei
2017-12-01
The development of science and technology has fundamentally changed people's lives and the way that medical systems function. Increasingly, mobile technologies are being introduced and integrated into classroom teaching and clinical applications, resulting in healthcare providers introducing innovative applications into health education. These applications enhance the clinical, education, and research expertise of medical staffs and nurses, while improving quality of care and providing new experiences for patients. In order to understand the current situation and trends in nursing education, the present study adopted literature analysis to explore the influence and effect of mobile technologies that have been introduced into nursing education from the school and clinical environments. The results found that students hold positive attitudes toward introducing these technologies into their curricula. Although these technologies may increase the work efficiency of nurses in the workplace, questions remain user perceptions and professional expression. Therefore, securing patient agreement and healthcare system approval were major turning points in the introduction of mobile technologies into nursing education. In the future, adapting mobile technologies for use in teaching materials and courses may be further developed. Moreover, empirical studies may be used in future research in order to facilitate the increasingly successful integration of relevant technologies into nursing education.

A number of recent, highly-publicized, perceived health-care service failures have raised concerns about health professionals' accountabilities. Relevant to these concerns, the present study sought to examine how mental health nurses understood clinical responsibility and its impact on their practice. A descriptive, qualitative design was used, and a convenience sample of 10 mental health nurses was recruited from specialist inpatient and outpatient mental health settings in Canterbury, New Zealand. Data were collected using semistructured interviews, and the transcriptions were analysed using an inductive, descriptive approach. Three major themes were identified: being accountable, fostering patient responsibility, and shifting responsibility. Being accountable involved weighing up patients' therapeutic needs against the potential for blame in an organizational culture of risk management. Fostering patient responsibility described the process of deciding in what situations patients could take responsibility for their behaviour. Shifting responsibility described the culture of defensive practice fostered by the organizational culture of risk aversion. The present study highlighted the challenges mental health nurses experience in relation to clinical responsibility in practice, including the balancing required between the needs of patients, the needs of the organization, and the perceived need for self-protection. © 2014 Australian College of Mental Health Nurses Inc.
Facing two faces: Defense activation varies as a function of personal relevance.
Bublatzky, Florian; Alpers, Georg W
2017-04-01
It can be unsettling to be watched by a group of people, and when they express anger or hostility, this can prime defensive behavior. In contrast, when others smile at us, this may be comforting. This study tested to which degree the impact of facial expressions (happy, neutral, and angry) varies with the personal relevance of a social situation. Modelling a triadic situation, two faces looked either directly at the participant, faced each other, or they were back to back. Results confirmed that this variation constitutes a gradient of personal relevance (directed frontally > towards > away), as reflected by corresponding defensive startle modulation and autonomic nervous system activity. This gradient was particularly pronounced for angry faces and it was steeper in participants with higher levels of social anxiety. Thus, sender-recipient constellations modulate the processing of facial emotions in favor of adequate behavioral responding (e.g., avoidance) in group settings. Copyright © 2017 Elsevier B.V.

RBE, reference RBE and clinical RBE: applications of these concepts in hadron therapy.
Wambersie, A
1999-06-01
Introduction of heavy particles (hadrons) into radiation therapy aims at improving the physical selectivity of the irradiation (e.g. proton beams), or the radiobiological differential effect (e.g. fast neutrons), or both (e.g. heavy-ion beams). Each of these new therapy modalities requires several types of information before prescribing safely the doses to patients, as well as for recording and reporting the treatments: (i) absorbed dose measured in a homogeneous phantom in reference conditions; (ii) dose distribution computed at the level of the target volume(s) and the normal tissues at risk; (iii) radiation quality from which a RBE evaluation could be predicted and (iv) RBE measured on biological systems or derived from clinical observation. In hadron therapy, the RBE of the different beams raises specific problems. For fast neutrons, the RBE varies within wide limits (about 2 to 5) depending on the neutron energy spectrum, dose, and biological system. For protons, the RBE values range between smaller limits (about 1.0 to 1.2). A clinical benefit can thus not be expected from RBE differences. However, the proton RBE problem cannot be ignored since dose differences of about 5% can be detected clinically in some cases. The situation is most complex with heavy ions since RBE variations are at least as large as for fast neutrons, as a function of particle type and energy, dose and biological system. In addition, RBE varies with depth. Radiation quality thus has to be taken into account when prescribing and reporting a treatment. This can be done in different ways: (a) description of the method of beam production; (b) computed LET spectra and/or measured microdosimetric spectra at the points clinically relevant; (c) RBE determination. The most relevant RBE data are those obtained for late tolerance of normal tissues at 2 Gy per fraction ("reference RBE"). The "clinical RBE" selected by the radiation oncologist when prescribing the treatment will be close to the reference RBE, but other factors (such as heterogeneity in dose distribution) may influence the selection of the clinical RBE. Combination of microdosimetric data and experimental RBE values improves the confidence in both sets of data.

This article explores the nature of instructional communication in responding to crisis situations. Through the lens of chaos theory, the relevance of instructional messages in restoring order is established. This perspective is further advanced through an explanation of how various learning styles impact the receptivity of various instructional messages during the acute phase of crises. We then summarize an exploratory study focusing on the relationship between learning styles and the demands of instructional messages in crisis situations. We conclude the article with a series of conclusions and implications. © 2011 Society for Risk Analysis.

In this article we describe the role of “clinical scenario” information to assure the safety of interoperable systems, as well as the system’s ability to deliver the requisite clinical functionality to improve clinical care. Described are methods and rationale for capturing the clinical needs, workflow, hazards, and device interactions in the clinical environment. Key user (clinician and clinical engineer) needs and system requirements can be derived from this information, therefore improving the communication from clinicians to medical device and information technology system developers. This methodology is intended to assist the health care community, including researchers, standards developers, regulators, and manufacturers, by providing clinical definition to support requirements in the systems engineering process, particularly those focusing on development of Integrated Clinical Environments described in standard ASTM F2761. Our focus is on identifying and documenting relevant interactions and medical device capabilities within the system using a documentation tool called medical device interface data sheets (MDIDSa) and mitigating hazardous situations related to workflow, product usability, data integration, and the lack of effective medical device-health information technology system integration to achieve safe interoperability. Portions of the analysis of a clinical scenario for a “Patient-controlled analgesia safety interlock” are provided to illustrate the method. Collecting better clinical adverse event information and proposed solutions can help identify opportunities to improve current device capabilities and interoperability and support a Learning Health System to improve health care delivery. Developing and analyzing clinical scenarios are the first steps in creating solutions to address vexing patient safety problems and enable clinical innovation. A web-based research tool for implementing a means of acquiring and managing this information, the Clinical Scenario Repository™, is described. PMID:27387840

Diverse clinical advancements, together with some relevant technical innovations, have led to an increase in popularity of tunneling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession-type defects, tunneling flap procedures may now be applied successfully in a variety of clinical situations in which augmentation of the soft tissues is indicated in the esthetic zone. Potential clinical scenarios include surgical thickening of thin buccal gingiva or peri-implant mucosa, alveolar ridge/socket preservation and implant second-stage surgery, as well as soft-tissue ridge augmentation or pontic site development. In this way, tunneling flap procedures developed from a technique, originally merely intended for surgical root coverage, into a capacious surgical conception in plastic periodontal and implant surgery. The purpose of this article is to provide a comprehensive overview on tunneling flap procedures, to introduce the successive development of the approach along with underlying ideas on surgical wound healing and to present contemporary clinical scenarios in step-by-step photograph-illustrated sequences, which aim to provide clinicians with guidance to help them integrate tunneling flap procedures into their daily clinical routine. © 2018 John Wiley & Sons A/S.

Social withdrawal is a new mental health problem increasingly common, present in different cultures, whose psychopathology and treatment is not yet established. This study aims to determine the socio-demographic and clinical features and possible clinical subtypes that predict the 12-month outcomes of cases with hikikomori syndrome, a severe form of social withdrawal. Socio-demographic and clinical data at baseline were analysed as well as data obtained for 12 months after at-home treatment in 190 cases. The inclusion criteria were: spending all time at home, avoiding social situations and relationships, significant deterioration due to social isolation, with a minimum duration of 6 months. Six major diagnostic groups were identified: affective, anxiety, psychotic, drug use, personality and other Axis I disorders. The anxiety-affective subgroup demonstrated lower clinical severity, but worse evolution. Less than half of the cases were available for medical follow-up at 12-months. Subjects undergoing intensive treatment had a higher medical follow-up rate and better social networks at 12-months. Therefore, our findings provide data to reach consensus on the specific characteristics of social isolation hikikomori syndrome. The analysis demonstrated the fragility and tendency to relapse and have disengagement, particularly relevant in the anxiety-affective subgroup, suggesting that intensive treatments are more effective.

We contrast 3 theoretical viewpoints concerning the factors affecting social categorization by race: (a) the classical theory of social categorization highlighting the role of a priori accessibility and situational factors, (b) the classical theory augmented by a principle of competitive category use, and (c) competition between race (but not gender) and coalition with race (but not gender) encoded only as a proxy to coalition. Study 1 documents a confound that renders important portions of previous research difficult to interpret. In Studies 2 and 3, race categorization was stronger than categorization by more weakly accessible categories when situational support in terms of topic relevance was comparable across categories. A situational focus on race further increased race categorization. Race categorization was reduced in the presence of strongly cued cross-cutting coalitions. Race categorization also was depressed when situational factors promoted comparative processing of cross-cutting categories while cues to potential coalitional divisions were held constant (Study 4). Accessibility, topic relevance, and cuing cross-cutting coalitions had the same effects on gender categorization as found for race categorization (Study 5). Taken together, the results suggest that classical theories of social categorization have to be augmented by a principle of competitive category use that is not limited to a competition between race and coalition.

Hypothyroidism has multiple etiologies and manifestations. Appropriate treatment requires an accurate diagnosis and is influenced by coexisting medical conditions. This paper describes evidence-based clinical guidelines for the clinical management of hypothyroidism in ambulatory patients. The development of these guidelines was commissioned by the American Association of Clinical Endocrinologists (AACE) in association with American Thyroid Association (ATA). AACE and the ATA assembled a task force of expert clinicians who authored this article. The authors examined relevant literature and took an evidence-based medicine approach that incorporated their knowledge and experience to develop a series of specific recommendations and the rationale for these recommendations. The strength of the recommendations and the quality of evidence supporting each was rated according to the approach outlined in the American Association of Clinical Endocrinologists Protocol for Standardized Production of Clinical Guidelines-2010 update. Topics addressed include the etiology, epidemiology, clinical and laboratory evaluation, management, and consequences of hypothyroidism. Screening, treatment of subclinical hypothyroidism, pregnancy, and areas for future research are also covered. Fifty-two evidence-based recommendations and subrecommendations were developed to aid in the care of patients with hypothyroidism and to share what the authors believe is current, rational, and optimal medical practice for the diagnosis and care of hypothyroidism. A serum thyrotropin is the single best screening test for primary thyroid dysfunction for the vast majority of outpatient clinical situations. The standard treatment is replacement with L-thyroxine. The decision to treat subclinical hypothyroidism when the serum thyrotropin is less than 10 mIU/L should be tailored to the individual patient.

Socially relevant situations that involve strategic interactions are widespread among animals and humans alike. To study these situations, theoretical and experimental research has adopted a game theoretical perspective, generating valuable insights about human behavior. However, most of the results reported so far have been obtained from a population perspective and considered one specific conflicting situation at a time. This makes it difficult to extract conclusions about the consistency of individuals' behavior when facing different situations and to define a comprehensive classification of the strategies underlying the observed behaviors. We present the results of a lab-in-the-field experiment in which subjects face four different dyadic games, with the aim of establishing general behavioral rules dictating individuals' actions. By analyzing our data with an unsupervised clustering algorithm, we find that all the subjects conform, with a large degree of consistency, to a limited number of behavioral phenotypes (envious, optimist, pessimist, and trustful), with only a small fraction of undefined subjects. We also discuss the possible connections to existing interpretations based on a priori theoretical approaches. Our findings provide a relevant contribution to the experimental and theoretical efforts toward the identification of basic behavioral phenotypes in a wider set of contexts without aprioristic assumptions regarding the rules or strategies behind actions. From this perspective, our work contributes to a fact-based approach to the study of human behavior in strategic situations, which could be applied to simulating societies, policy-making scenario building, and even a variety of business applications.
Getting through to circadian oscillators: why use constant routines?
NASA Technical Reports Server (NTRS)
Duffy, Jeanne F.; Dijk, Derk-Jan
2002-01-01
Overt 24-h rhythmicity is composed of both exogenous and endogenous components, reflecting the product of multiple (periodic) feedback loops with a core pacemaker at their center. Researchers attempting to reveal the endogenous circadian (near 24-h) component of rhythms commonly conduct their experiments under constant environmental conditions. However, even under constant environmental conditions, rhythmic changes in behavior, such as food intake or the sleep-wake cycle, can contribute to observed rhythmicity in many physiological and endocrine variables. Assessment of characteristics of the core circadian pacemaker and its direct contribution to rhythmicity in different variables, including rhythmicity in gene expression, may be more reliable when such periodic behaviors are eliminated or kept constant across all circadian phases. This is relevant for the assessment of the status of the circadian pacemaker in situations in which the sleep-wake cycle or food intake regimes are altered because of external conditions, such as in shift work or jet lag. It is also relevant for situations in which differences in overt rhythmicity could be due to changes in either sleep oscillatory processes or circadian rhythmicity, such as advanced or delayed sleep phase syndromes, in aging, or in particular clinical conditions. Researchers studying human circadian rhythms have developed constant routine protocols to assess the status of the circadian pacemaker in constant behavioral and environmental conditions, whereas this technique is often thought to be unnecessary in the study of animal rhythms. In this short review, the authors summarize constant routine methodology and what has been learned from constant routines and argue that animal and human circadian rhythm researchers should (continue to) use constant routines as a step on the road to getting through to central and peripheral circadian oscillators in the intact organism.
A personality trait-based interactionist model of job performance.
Tett, Robert P; Burnett, Dawn D
2003-06-01
Evidence for situational specificity of personality-job performance relations calls for better understanding of how personality is expressed as valued work behavior. On the basis of an interactionist principle of trait activation (R. P. Tett & H. A. Guterman, 2000), a model is proposed that distinguishes among 5 situational features relevant to trait expression (job demands, distracters, constraints, releasers, and facilitators), operating at task, social, and organizational levels. Trait-expressive work behavior is distinguished from (valued) job performance in clarifying the conditions favoring personality use in selection efforts. The model frames linkages between situational taxonomies (e.g., J. L. Holland's [1985] RIASEC model) and the Big Five and promotes useful discussion of critical issues, including situational specificity, personality-oriented job analysis, team building, and work motivation.

Nursing students' assessment of the learning environment in different clinical settings.
Bisholt, Birgitta; Ohlsson, Ulla; Engström, Agneta Kullén; Johansson, Annelie Sundler; Gustafsson, Margareta

Nursing students perform their clinical practice in different types of clinical settings. The clinical learning environment is important for students to be able to achieve desired learning outcomes. Knowledge is lacking about the learning environment in different clinical settings. The aim was to compare the learning environment in different clinical settings from the perspective of the nursing students. A cross-sectional study with comparative design was conducted. Data was collected from 185 nursing students at three universities by means of a questionnaire involving the Clinical Learning Environment, Supervision and Nurse Teacher (CLES + T) evaluation scale. An open-ended question was added in order to ascertain reasons for dissatisfaction with the clinical placement. The nursing students' satisfaction with the placement did not differ between clinical settings. However, those with clinical placement in hospital departments agreed more strongly that sufficient meaningful learning situations occurred and that learning situations were multi-dimensional. Some students reported that the character of the clinical setting made it difficult to achieve the learning objectives. In the planning of the clinical placement, attention must be paid to whether the setting offers the student a meaningful learning situation where the appropriate learning outcome may be achieved.

Relevance of Micro-leakage to Orthodontic Bonding - a Review
M, Karandish
2016-01-01
As it is seen, by passing the evolutionary process of banding of orthodontic attachments to the bonding ones, orthodontics have witnessed many developments, such as application of new adhesives, optimized base designs, new bracket materials, curing methods and more efficient primers. The studies often address the morphological, micro-leakage, and shear bond tests to evaluate bond efficacy. Among studies endeavored to develop the bond strength of brackets, some observed the reduction of micro-leakage of bracket-adhesive and enamel-adhesive interfaces. Owing to the importance of micro-leakage in orthodontics, this study aimed at reviewing the micro-leakage values directly relevant to the enamel decay and debonding of the brackets. To reach the best bond strength, the researchers tried to design different studies to evaluate the effect of variables and prevent any possible side effects in clinical situations. It is noticed that most studies have mainly focused on adhesives, enamel preparation and methods of curing which are discussed in this review. The literature was reviewed by searching databases, using micro-leakage and orthodontic bonding as the keywords . Having found the relevant studies, the researchers entered them into the database. After reviewing numerous studies conducted in this field, the type of adhesive or curing method was not found to have determinative role in the value of micro-leakage although more standardized studies are needed.

Before starting a new animal experiment, thorough analysis of previously performed experiments is essential from a scientific as well as from an ethical point of view. The method that is most suitable to carry out such a thorough analysis of the literature is a systematic review (SR). An essential first step in an SR is to search and find all potentially relevant studies. It is important to include all available evidence in an SR to minimize bias and reduce hampered interpretation of experimental outcomes. Despite the recent development of search filters to find animal studies in PubMed and EMBASE, searching for all available animal studies remains a challenge. Available guidelines from the clinical field cannot be copied directly to the situation within animal research, and although there are plenty of books and courses on searching the literature, there is no compact guide available to search and find relevant animal studies. Therefore, in order to facilitate a structured, thorough and transparent search for animal studies (in both preclinical and fundamental science), an easy-to-use, step-by-step guide was prepared and optimized using feedback from scientists in the field of animal experimentation. The step-by-step guide will assist scientists in performing a comprehensive literature search and, consequently, improve the scientific quality of the resulting review and prevent unnecessary animal use in the future.
Drug-induced cholestasis: mechanisms, models, and markers.
Chatterjee, Sagnik; Annaert, Pieter
2018-04-27
Drug-induced cholestasis is a risk factor in progression of drug candidates, and poses serious health hazard if not detected before going into human. Intrahepatic accumulation of bile acids (BAs) represents a characteristic phenomenon associated with drug-induced cholestasis. The major challenges in obtaining a complete understanding of drug-induced cholestasis lies in the complexity of BA-mediated toxicity mechanisms and the impact of bile acids at different 'targets' such as transporters, enzymes and nuclear receptors. At the same time, it is not trivial to have a relevant in vitro system that recapitulates these features. In addition, lack of sensitive and early preclinical biomarkers, relevant to the clinical situation, complicates proper detection of drug-induced cholestasis. Significant overlap in biomarker signatures between different mechanisms of drug-induced liver injury (DILI) precludes identification of specific mechanisms. Over the last decade the knowledge gaps in drug-induced cholestasis are closing due to growing mechanistic understanding of BA-mediated toxicity at (patho)physiologically relevant BA concentrations. Significant progress has been made in the mechanistic understanding of drug-induced cholestasis and associated toxicity, biomarkers and susceptibility factors. In addition, novel in vitro models are evolving which provide a holistic understanding of processes underlying drug-induced cholestasis. This review summarizes the challenges and recent understandings about drug-induced cholestasis with a potential path forward.

Suicide in developing countries (2): risk factors.
Vijayakumar, Lakshmi; John, Sujit; Pirkis, Jane; Whiteford, Harvey
2005-01-01
The majority of studies on risk factors for suicide have been conducted in developed countries, and less work has been done to systematically profile risk factors in developing countries. The current paper presents a selective review of sociodemographic, clinical, and environmental/situational risk factors in developing countries. Taken together, the evidence suggests that the profiles of risk factors in developing countries demonstrate some differences from those in developed countries. In some developing countries, at least, being female, living in a rural area, and holding religious beliefs that sanction suicide may be of more relevance to suicide risk than these factors are in developed countries. Conversely, being single or having a history of mental illness may be of less relevance. Risk factors that appear to be universal include youth or old age, low socioeconomic standing, substance use, and previous suicide attempts. Recent stressful life events play a role in both developing and developed countries, although their nature may differ (e.g., social change may have more of an influence in the former). Likewise, access to means heightens risk in both, but the specific means may vary (e.g., access to pesticides is of more relevance in developing countries). These findings have clear implications for suicide prevention, suggesting that preventive efforts that have shown promise in developed countries may need to be tailored differently to address the risk factor profile of developing countries.

Cold physical plasma has been suggested as a new anticancer tool recently. However, direct use of plasma is limited to visible tumors and in some clinical situations not feasible. This includes repetitive treatment of peritoneal metastases which commonly occur in advanced gastrointestinal cancer and in pancreatic cancer in particular. In case of diffuse intraperitoneal metastatic spread Hyperthermic Intraperitoneal Intraoperative Chemotherapy (HIPEC) is used as therapeutic approach. Plasma treated solutions may combine their suspected systemic non-toxic characteristics with the anticancer effects of HIPEC. Previous work has provided evidence for an anti-cancer efficacy of plasma treated cell culture medium but the clinical relevance of such an approach is low due to its complex formulation and lack of medical accreditation. Therefore, plasma treated phosphate-buffered saline (PBS) which closely resembles medically certified solutions was investigated for its cytotoxic effect on 2D monolayer murine pancreatic cancer cells in vitro. It significantly decreased cancer cell metabolisms and proliferation whereas plasma treated Dulbecco's Modified Eagle Medium had no effect. Moreover, tumor cell growth attenuation was significantly higher when compared to syngeneic primary murine fibroblasts. Both results were confirmed in a human pancreatic cancer cell line. Finally, plasma treated PBS also decreased tumor sizes of pancreatic tumors in the TUM-CAM model in a three-dimensional manner, and induction of apoptosis was found to be responsible for all anticancer effects identified. Altogether, plasma treated PBS inhibited cell growth in 2D and 3D models of cancer. These results may help facilitating the development of new plasma derived anticancer agent with clinical relevance in the future.

In modern practice, doctors who outright lie to their patients are often condemned, yet those who employ non-lying deceptions tend to be judged less critically. Some areas of non-disclosure have recently been challenged: not telling patients about resuscitation decisions; inadequately informing patients about risks of alternative procedures and withholding information about medical errors. Despite this, there remain many areas of clinical practice where non-disclosures of information are accepted, where lies about such information would not be. Using illustrative hypothetical situations, all based on common clinical practice, we explore the extent to which we should consider other deceptive practices in medicine to be morally equivalent to lying. We suggest that there is no significant moral difference between lying to a patient and intentionally withholding relevant information: non-disclosures could be subjected to Bok's 'Test of Publicity' to assess permissibility in the same way that lies are. The moral equivalence of lying and relevant non-disclosure is particularly compelling when the agent's motivations, and the consequences of the actions (from the patient's perspectives), are the same. We conclude that it is arbitrary to claim that there is anything inherently worse about lying to a patient to mislead them than intentionally deceiving them using other methods, such as euphemism or non-disclosure. We should question our intuition that non-lying deceptive practices in clinical practice are more permissible and should thus subject non-disclosures to the same scrutiny we afford to lies.

The effects of drama versus lecture format in public service advertisements are studied in a 2 (format) x 2 (malaria vs AIDS) factorial design. Two structural equation models are built (one for each level of self-relevance), showing two distinct patterns. In both low and high self-relevant situations, empathy plays a key role. Under low self-relevance conditions, drama enhances information processing through empathy. Under high self-relevant conditions, the advertisement format has neither significant cognitive or empathetic effects. The information processing generated by the highly relevant topic affects viewers' empathy, which in turn affects the attitude the advertisement and the behavioral intent. As predicted by the Elaboration Likelihood Model, the advertisement format enhances the attitudes and information processing mostly under low self-relevant conditions. Under low self-relevant conditions, empathy enhances information processing while under high self-relevance, the converse relation holds.

Seven experiments assessed the hypothesis derived from terror management theory that reminding people of their mortality would increase accessibility of constructs central to their worldview. Experiment 1 found that mortality primes, relative to control primes, increased accessibility of nationalistic constructs for men but not for women. Experiment 2 replicated this finding and also found that mortality salience increased romantic accessibility for women but not for men. Four subsequent experiments supported the role of unconscious death-related ideation in producing these effects. A final experiment demonstrated that situational primes can increase the accessibility of nationalistic constructs for women after mortality salience. The roles of situational cues and individual differences in the effects of exposure to death-related stimuli on worldview-relevant construct accessibility are discussed.
Optimized model tuning in medical systems.
Kléma, Jirí; Kubalík, Jirí; Lhotská, Lenka
2005-12-01
In medical systems it is often advantageous to utilize specific problem situations (cases) in addition to or instead of a general model. Decisions are then based on relevant past cases retrieved from a case memory. The reliability of such decisions depends directly on the ability to identify cases of practical relevance to the current situation. This paper discusses issues of automated tuning in order to obtain a proper definition of mutual case similarity in a specific medical domain. The main focus is on a reasonably time-consuming optimization of the parameters that determine case retrieval and further utilization in decision making/ prediction. The two case studies - mortality prediction after cardiological intervention, and resource allocation at a spa - document that the optimization process is influenced by various characteristics of the problem domain.

The purpose of this investigation was to identify evidence-based clinical trials to aid dental clinicians in establishing the efficacy for recommending or prescribing analgesics for pain of endodontic origin. The authors prepared and registered a protocol on PROSPERO and conducted electronic searches in MEDLINE, Scopus, the Cochrane Library, and ClinicalTrials.gov. In addition, the authors manually searched the bibliographies of all relevant articles, the gray literature, and textbooks for randomized controlled trials. Two authors selected the relevant articles independently. There were no disagreements between the authors. The authors analyzed 27 randomized, placebo-controlled trials. The authors divided the studies into 2 groups: preoperative and postoperative analgesic treatments. There was moderate evidence to support the use of steroids for patients with symptomatic irreversible pulpitis. Also, there was moderate evidence to support nonsteroidal anti-inflammatory drugs (NSAIDs) preoperatively or postoperatively to control pain of endodontic origin. When NSAIDs were not effective, a combination of NSAIDs with acetaminophen, tramadol, or an opioid appeared beneficial. NSAIDs should be considered as the drugs of choice to alleviate or minimize pain of endodontic origin if there are no contraindications for the patient to ingest an NSAID. In situations in which NSAIDs alone are not effective, the combination of an NSAID with acetaminophen or a centrally acting drug is recommended. Steroids appear effective in irreversible pulpitis.

In order for patients to adhere to healthcare advice, it is essential that they are able to recall this following a consultation. Although psychological research exists which highlights techniques and factors postulated to influence recall, only a limited body of work has been conducted to evaluate their effectiveness in a clinical context. To carry out a systematic review of intervention trials designed to enhance recall of medical information. We searched Medline (1950-April 2007); Embase (1980-April 2007); Cinahl (1982-April 2007); PsychINFO (1969-2007); and the Cochrane Library Collection. Secondary searches were made through reference to relevant journals and reference lists from relevant papers/review papers. From 69 papers provisionally identified, 34 papers met the inclusion criteria. Nine recall interventions had been evaluated (audio recordings, written materials, adjunct questions, prompt sheets, visual aids, cognitive strategies, rehearsal, communication styles and personalized teaching). Despite the experimental and theoretical evidence which could have informed cognitive interventions to enhance recall of healthcare advice, most studies primarily focused on the use of written and/or audio-recorded medical instructions. Although the majority of studies supported these approaches insofar as they enhanced recall, the findings were equivocal. While written and tape-recorded instructions appear to improve recall in most situations, a dearth of interventions incorporating psychological theory was readily apparent. Further research is required in clinical settings to determine if cognitive interventions based on a more over-arching psychological model of recall are effective.

In this text we compare children's expressions in drawings to their statements during interviews, for the purpose of understanding how different situations afford children to make meaning. In specific we study how two different activities interact and afford children to make meaning differently about the human body. The analytic attention is drawn to the meaning-making the children made as they in pairs were asked to explain the body drawings that they did prior to the interviews. Meaning-making was studied by using a practical epistemology analysis, an analysis facilitating understanding of how relations are established in a developing conversation, and more generally providing understanding from a child perspective. The results indicate that several reasons are at hand for children in the two different situations; namely, social, artistic, practical, empirical and memory reasons are identified. Social reasons refer to statements belonging to the social context and items that were described as inappropriate to express. Artistic reasons were interpreted from aesthetic judgements, referring to the artistic quality of the drawing. Practical reasons were given in situations where children expressed, for example, that the space limited their opportunities to draw. Empirical reasons are built on children's statements referring to picture items that are identified by pointing or touching their own body. Memory reasons are involved in all the situations where children explained items were previously omitted, because the body part had been temporarily forgotten. Furthermore, we suggest that children interpret situational aspects and make judgements concerning the relevance of their different reasons. By these means we hope to facilitate children's understanding of interview questions and also to improve researchers' understanding of children's ability to grasp relevant details prior to their response (or participation).

Concern over polyethylene wear particle induced aseptic loosening of metal-on-polyethylene hip prostheses has led to renewed interest in alternative materials such as metal-on-metal and alumina ceramic-on-alumina ceramic for total hip replacement. This study compared the effects of clinically relevant cobalt-chromium and alumina ceramic wear particles on the viability of U937 histiocytes and L929 fibroblasts in vitro. Clinically relevant cobalt-chromium wear particles were generated using a flat pin-on-plate tribometer. The mean size of the clinically relevant metal particles was 29.5+/-6.3 nm (range 5-200 nm). Clinically relevant alumina ceramic particles were generated in the Leeds MkII anatomical hip simulator from a Mittelmieier prosthesis using micro-separation motion. This produced particles with a bimodal size distribution. The majority (98%) of the clinically relevant alumina ceramic wear debris was 5-20 nm in size. The cytotoxicity of the clinically relevant wear particles was compared to commercially available cobalt-chromium (9.87 microm+/-5.67) and alumina ceramic (0.503+/-0.19 microm) particles. The effects of the particles on the cells over a 5 day period at different particle volume (microm(3)) to cell number ratios were tested and viability determined using ATP-Lite(TM). Clinically relevant cobalt-chromium particles 50 and 5 microm(3) per cell reduced the viability of U937 cells by 97% and 42% and reduced the viability of L929 cells by 95% and 73%, respectively. At 50 microm(3) per cell, the clinically relevant ceramic particles reduced U937 cell viability by 18%. None of the other concentrations of the clinically relevant particles were toxic. The commercial cobalt-chromium and alumina particles did not affect the viability of either the U937 histiocytes or the L929 fibroblasts.Thus at equivalent particle volumes the clinically relevant cobalt-chromium particles were more toxic then the alumina ceramic particles. This study has emphasised the fact that the nature, size and volume of particles are important in assessing biological effects of wear debris on cells in vitro.

Proton therapy is a radiotherapy, based on the use of protons, charged subatomic particles that stop at a given depth depending on their initial energy (pristine Bragg peak), avoiding any output beam, unlike the photons used in most of the other modalities of radiotherapy. Proton therapy has been used for 60 years, but has only become ubiquitous in the last decade because of recent major advances in particle accelerator technology. This article reviews the history of clinical implementation of protons, the nature of the technological advances that now allows its expansion at a lower cost. It also addresses the technical and physical specificities of proton therapy and the clinical situations for which proton therapy may be relevant but requires evidence. Different proton therapy techniques are possible. These are explained in terms of their clinical potential by explaining the current terminology (such as cyclotrons, synchrotrons or synchrocyclotrons, using superconducting magnets, fixed line or arm rotary with passive diffusion delivery or active by scanning) in basic words. The requirements associated with proton therapy are increased due to the precision of the depth dose deposit. The learning curve of proton therapy requires that clinical indications be prioritized according to their associated uncertainties (such as range uncertainties and movement in lung tumors). Many clinical indications potentially fall under proton therapy ultimately. Clinical strategies are explained in a paralleled manuscript. Copyright © 2018 Société Française du Cancer.

GPs need to consider assorted relevant non-medical factors, such as family or work situations or health insurance coverage, to determine appropriate patient care. If GPs' knowledge of these factors varies according to patients' social position, less advantaged patients might receive poorer care, resulting in the perpetuation of social inequalities in health. To assess social disparities in GPs' knowledge of non-medical factors relevant to patient care. Observational survey of GPs who supervise internships in the Paris metropolitan area. Each of the 52 enrolled GPs randomly selected 70 patients from their patient list. Their knowledge of five relevant factors (coverage by publicly funded free health insurance, or by supplementary health insurance, living with a partner, social support and employment status) was analysed as the agreement between the patients' and GPs' answers to matching questions. Occupational, educational and financial disparities were estimated with multilevel models adjusted for age, sex, chronic disease and GP-patient relationship. Agreement varied according to the factor considered from 66% to 91%. The global agreement score (percentage of agreement for all five factors) was 72%. Social disparities and often gradients, disfavouring the less well-off patients, were observed for each factor considered. Social gradients were most marked according to perceived financial situation and for health insurance coverage. GPs must be particularly attentive toward their least advantaged patients, to be aware of the relevant non-medical factors that affect these patients' health and care, and thus provide management adapted to each individual's personal situation. © The Author(s) 2018.

The aim of this investigation was to study the clinical prosthodontic decision-making process relating to dentitions with compromised molars among Swedish general dental practitioners (GDPs). Eleven Swedish GDPs were purposively selected, and all agreed to participate. Then, in-depth, semi-structured interviews were conducted and covered treatment considerations concerning two authentic patient cases, initially with complete dental arches, and later, a final treatment based on a shortened dental arch (SDA) was discussed. The cases involved patients with compromised teeth situated mainly in the molar regions. One patient suffered from extensive caries and the other from severe periodontal disease. Qualitative content analysis was used to analyse the data. In the systematic analysis, two main categories were identified: holistic and functional approach. Among the interviewed GDPs, focus was put on patients' needs, background history and motivation for treatment as well as the preservation of molar support. Within the limitations of this study, the following can be concluded: keeping a dental arch with molars seems to be important to Swedish general dental practitioners. The SDA concept does not seem to have a substantial impact on the prosthodontic decision-making relating to dentitions with compromised molars. The dentist's experiences, as well as colleagues' or consulting specialist advice together with aetiological factors and the patient's individual situation, influence the decision-making more than the SDA concept. The conflicting results in the prosthetic decision-making process concerning the relevance of age and the need for molar support need further investigation, for example based on decisions made in the dentist's own clinical practice. © 2016 John Wiley & Sons Ltd.

Interpretations of negative, positive, and ambiguous situations were examined in individuals with generalized anxiety disorder (GAD), other anxiety disorders (ANX), and no psychiatric condition (CTRL). Additionally, relationships between specific beliefs about uncertainty (Uncertainty Has Negative Behavioral and Self-Referent Implications [IUS-NI], and Uncertainty Is Unfair and Spoils Everything [IUS-US]) and interpretations were explored. The first hypothesis (that the clinical groups would report more concern for negative, positive, and ambiguous situations than would the CTRL group) was supported. The second hypothesis (that the GAD group would report more concern for ambiguous situations than would the ANX group) was not supported; both groups reported similar levels of concern for ambiguous situations. Exploratory analyses revealed no differences between the GAD and ANX groups in their interpretations of positive and negative situations. Finally, the IUS-US predicted interpretations of negative and ambiguous situations in the full sample, whereas the IUS-NI did not. Clinical implications are discussed. Copyright © 2012 Elsevier Ltd.

A thorough understanding of the role of human factors in error in health care for improving patient safely is paramount. One area particularly crucial for optimising clinical performance is the recognising the importance of situational awareness. Loss of situation awareness can occur in many different settings, particularly during stressful and unexpected situations. Tunnel vision is a classic example where clinicians focus on one aspect of care, often to the detriment of overall patient management. Loss of situational awareness can result in serious compromise to patient safety if it is not recognised by either the individual or clinical team. We provide an introduction to situational awareness for those not familiar with it, including some important theory which explains how awareness can be lost, and discuss the important approaches we use in our day-to-day practice to safeguard both patients and clinicians in the workplace environment. © 2016 John Wiley & Sons A/S.

To test a potential treatment for social phobia, which provides exposure to phobia-inducing situations via computer-generated, three-dimensional images, using an open clinical trial design. Twenty-one patients with a DSM-IV diagnosis of social phobia took part in the trial. Treatment consisted of up to 12 sessions of exposure to relevant images, each session lasting 50 minutes. Improvements in social anxiety were seen in all scales and instruments used, including at follow-up 6 months after the end of treatment. The average number of sessions was seven, as the participants habituated rapidly to the process. Only one participant dropped out. This study provides evidence that exposure to computer-generated three-dimensional images is relatively inexpensive, leads to greater treatment adherence, and can reduce social anxiety. Further studies are needed to corroborate these findings.
Allergens retained in clothing.

Some patients state compliance with avoidance of identified allergens, yet have persistent dermatitis in areas under tight-fitting clothing. To analyze a series of such cases to identify allergens most likely retained in clothing. Review of contact dermatitis clinic cases and identification of type and formula weight of allergens involved. High-formula-weight allergens and allergens present in medicament ointments are difficult to dissolve in laundry detergent and water and may be retained in clothing. Retention of allergens in clothing, even after washing, may explain recalcitrant dermatitis in a patient who states compliance with avoidance of a seemingly relevant allergen. Dermatologists should consider the possibility of allergen retention in clothing whenever a patient has only partial clearing after at least 1 month of attempted compliance with avoidance of identified allergens. Purchase of new clothing may be required to clear allergic contact dermatitis in this situation.

Background The efficacy of current anticancer treatments is far from satisfactory and many patients still die of their disease. A general agreement exists on the urgency of developing molecularly targeted therapies, although their implementation in the clinical setting is in its infancy. In fact, despite the wealth of preclinical studies addressing these issues, the difficulty of testing each targeted therapy hypothesis in the clinical arena represents an intrinsic obstacle. As a consequence, we are witnessing a paradoxical situation where most hypotheses about the molecular and cellular biology of cancer remain clinically untested and therefore do not translate into a therapeutic benefit for patients. Objective To present a computational method aimed to comprehensively exploit the scientific knowledge in order to foster the development of personalized cancer treatment by matching the patient's molecular profile with the available evidence on targeted therapy. Methods To this aim we focused on melanoma, an increasingly diagnosed malignancy for which the need for novel therapeutic approaches is paradigmatic since no effective treatment is available in the advanced setting. Relevant data were manually extracted from peer-reviewed full-text original articles describing any type of anti-melanoma targeted therapy tested in any type of experimental or clinical model. To this purpose, Medline, Embase, Cancerlit and the Cochrane databases were searched. Results and Conclusions We created a manually annotated database (Targeted Therapy Database, TTD) where the relevant data are gathered in a formal representation that can be computationally analyzed. Dedicated algorithms were set up for the identification of the prevalent therapeutic hypotheses based on the available evidence and for ranking treatments based on the molecular profile of individual patients. In this essay we describe the principles and computational algorithms of an original method developed to fully exploit the available knowledge on cancer biology with the ultimate goal of fruitfully driving both preclinical and clinical research on anticancer targeted therapy. In the light of its theoretical nature, the prediction performance of this model must be validated before it can be implemented in the clinical setting. PMID:20706624

Enhancing the Therapy Experience Using Principles of Video Game Design.
Folkins, John Wm; Brackenbury, Tim; Krause, Miriam; Haviland, Allison
2016-02-01
This article considers the potential benefits that applying design principles from contemporary video games may have on enhancing therapy experiences. Six principles of video game design are presented, and their relevance for enriching clinical experiences is discussed. The motivational and learning benefits of each design principle have been discussed in the education literature as having positive impacts on student motivation and learning and are related here to aspects of clinical practice. The essential experience principle suggests connecting all aspects of the experience around a central emotion or cognitive connection. The discovery principle promotes indirect learning in focused environments. The risk-taking principle addresses the uncertainties clients face when attempting newly learned skills in novel situations. The generalization principle encourages multiple opportunities for skill transfer. The reward system principle directly relates to the scaffolding of frequent and varied feedback in treatment. Last, the identity principle can assist clients in using their newly learned communication skills to redefine self-perceptions. These principles highlight areas for research and interventions that may be used to reinforce or advance current practice.
Antioxidants in Translational Medicine.
Schmidt, Harald H H W; Stocker, Roland; Vollbracht, Claudia; Paulsen, Gøran; Riley, Dennis; Daiber, Andreas; Cuadrado, Antonio

It is generally accepted that reactive oxygen species (ROS) scavenging molecules or antioxidants exert health-promoting effects and thus their consumption as food additives and nutraceuticals has been greatly encouraged. Antioxidants may be beneficial in situations of subclinical deficiency and increased demand or acutely upon high-dose infusion. However, to date, there is little clinical evidence for the long-term benefit of most antioxidants. Alarmingly, recent evidence points even to health risks, in particular for supplements of lipophilic antioxidants. The biological impact of ROS depends not only on their quantities but also on their chemical nature, (sub)cellular and tissue location, and the rates of their formation and degradation. Moreover, ROS serve important physiological functions; thus, inappropriate removal of ROS may cause paradoxical reductive stress and thereby induce or promote disease. Any recommendation on antioxidants must be based on solid clinical evidence and patient-relevant outcomes rather than surrogate parameters. Such evidence-based use may include site-directed application, time-limited high dosing, (functional) pharmacological repair of oxidized biomolecules, and triggers of endogenous antioxidant response systems. Ideally, these approaches need guidance by patient stratification through predictive biomarkers and possibly imaging modalities.
Bubble transport and sticking in gas embolotherapy
NASA Astrophysics Data System (ADS)
Bull, Joseph
2002-11-01
Pressure-driven bubble transport in a two-dimensional, bifurcating channel is investigated as a model of gas emboli transport in the microcirculation. Gas emboli are relevant to a number of clinical situations, and our particular interest is a novel gas embolotherapy technique, which involves using gas bubbles to occlude blood flow to tumors. This minimally invasive treatment modality allows selective delivery of emboli. The bubbles originate as 6 micron-diameter liquid droplets of perfluorocarbon (PFC), mixed in saline, and are injected into the vascular system. The droplet forms are small enough to pass through capillary beds, so they can circulate until the next stage of the therapy. By strategically placing an ultrasound source over the artery feeding the tumor, the droplets may be vaporized at that location. Our model is developed using the Stokes equation subject to interfacial and wall boundary conditions, and is solved using the boundary element method. The conditions under which bubbles 'stick' to the channel walls and occlude flow are investigated. Clinically, these results are important because the location and homogeneity of bubble sticking determines the degree of tumor necrosis and the efficacy of the treatment.
Advances in diagnosis and management of celiac disease.
Kelly, Ciarán P; Bai, Julio C; Liu, Edwin; Leffler, Daniel A
2015-05-01
Celiac disease is an autoimmune disorder that is induced by dietary gluten in genetically predisposed individuals. It has a prevalence of approximately 1% in many populations worldwide. New diagnoses have increased substantially, owing to increased awareness, better diagnostic tools, and probable real increases in incidence. The breadth of recognized clinical presentations continues to expand, making the disorder highly relevant to all physicians. Newer diagnostic tools, including serologic tests for antibodies against tissue transglutaminase and deamidated gliadin peptide, greatly facilitate diagnosis. Tests for celiac-permissive HLA-DQ2 and HLA-DQ8 molecules are useful in defined clinical situations. Celiac disease is diagnosed by histopathologic examination of duodenal biopsy specimens. However, according to recent controversial guidelines, a diagnosis can be made without a biopsy in certain circumstances, especially in children. Symptoms, mortality, and risk for malignancy each can be reduced by adherence to a gluten-free diet. This treatment is a challenge, however, because the diet is expensive, socially isolating, and not always effective in controlling symptoms or intestinal damage. Hence, there is increasing interest in developing nondietary therapies. Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.

Celiac disease is an autoimmune disorder induced by dietary gluten in genetically predisposed individuals. It has a prevalence of ∼1% in many populations worldwide. New diagnoses have increased substantially, due to increased awareness, better diagnostic tools, and probable, real increases in incidence. The breadth of recognized clinical presentations continues to expand, making the disorder highly relevant to all physicians. Newer diagnostic tools, including serologic tests for antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptide, greatly facilitate diagnosis. Tests for celiac-permissive HLA DQ2 and DQ8 molecules are useful in defined clinical situations. Celiac disease is diagnosed by histopathologic examination of duodenal biopsies. However, according to recent controversial guidelines, a diagnosis can be made without biopsy in certain circumstances, especially for children.

2017-10-01
Mindfulness practice, where an individual maintains openness, patience, and acceptance while focusing attention on a situation in a nonjudgmental way, can improve symptoms of anxiety, burnout, and depression. The practice is relevant for health care providers; however, the time commitment is a barrier to practice. For this reason, brief mindfulness interventions (eg, ≤ 4 hours) are being introduced. We systematically reviewed the literature from inception to January 2017 about the effects of brief mindfulness interventions on provider well-being and behavior. Studies that tested a brief mindfulness intervention with hospital providers and measured change in well-being (eg, stress) or behavior (eg, tasks of attention or reduction of clinical or diagnostic errors) were selected for narrative synthesis. Fourteen studies met inclusion criteria; 7 were randomized controlled trials. Nine of 14 studies reported positive changes in levels of stress, anxiety, mindfulness, resiliency, and burnout symptoms. No studies found an effect on provider behavior. Brief mindfulness interventions may be effective in improving provider well-being; however, larger studies are needed to assess an impact on clinical care. Published by Elsevier Inc.
Capillary glucose meter accuracy and sources of error in the ambulatory setting.
Lunt, Helen; Florkowski, Christopher; Bignall, Michael; Budgen, Christopher
2010-03-05
Hand-held glucose meters are used throughout the health system by both patients with diabetes and also by health care practitioners. Glucose meter technology is constantly evolving. The current generation of meters and strips are quick to use and require a very small volume of blood. This review aims to describe meters currently available in New Zealand, for use in the ambulatory setting. It also aims to discuss the limits of meter performance and provide technical information that is relevant to the clinician, using locally available data. Commoner causes and consequences of end-user (patient and health professional) error are illustrated using clinical case examples. No meter offers definite advantages over other meters in all clinical situations, rather meters should be chosen because they fit the needs of individual patients and because the provider is able to offer appropriate educational and quality assurance backup to the meter user. A broad understanding of the advantages and disadvantages of the subsidised meter systems available in New Zealand will help the health practitioner decide when it is in the best interests of their patients to change or update meter technology.

This in vitro study investigated possible morphological and chemical changes induced by glycine or sodium bicarbonate powder air polishing on machined and acid-etched titanium surfaces. The glycine powder (granulometry <65 μm) and sodium bicarbonate powder (granulometry <150 μm) were applied on 2 machined healing abutments and on 2 acid-etched healing abutments. The samples were characterized by scanning electron microscopy coupled with energy dispersive x-ray spectroscopy. The analyses were performed at different steps: (1) as received, right after opening the abutment packaging; (2) after 20 minutes air exposure; (3) after aging in artificial saliva; (4) after glycine or sodium bicarbonate powder air polishing for 5 seconds; (5) after repetition of steps 3 and 4 with longer time of polishing (20 seconds). Air polishing using glycine and sodium bicarbonate powder seemed to be safe for professional oral hygiene of titanium dental implants, although acid-etched abutments and abutments treated with bicarbonate harbored more salts. This might indicate a greater plaque accumulation in a clinical situation. However, this result has to be investigated in vivo to understand its clinical relevance.
Behavioural consequences of child abuse

Abstract Objective To discuss the consequences of abuse on childhood behavioural development, to highlight some behavioural clues that might alert physicians to ongoing child abuse, and to explore the specific role of the family physician in this clinical situation. Sources of information A systematic search was used to review relevant research, clinical review articles, and child protection agency websites. Main message A child’s behaviour is an outward manifestation of inner stability and security. It is a lens through which the family physician can observe the development of the child throughout his or her life. All types of abuse are damaging to children—physically, emotionally, and psychologically—and can cause long-term difficulties with behaviour and mental health development. Family physicians need to be aware of and alert to the indicators of child abuse and neglect so that appropriate interventions can be provided to improve outcomes for those children. Conclusion Child abuse might cause disordered psychological development and behaviour problems. Family physicians have an important role in recognizing behaviour clues that suggest child abuse and in providing help to protect children. PMID:23946022

In order to review the strengths and weaknesses of medical biochemistry practical curriculum for undergraduates and to generate ideas to improve it, a questionnaire was sent to 50 biochemistry faculty members selected (through simple random sampling method) from 42 medical colleges of Maharashtra, India. 39 responded to the questionnaire, representing a 78% response rate. The internal consistency of the questionnaire sections was found to be satisfactory (>0.7). The respondents did not agree that the ongoing curriculum was in alignment with learning outcomes (8%), that it encouraged active learning (28%), helped to apply knowledge to clinical situations (18%) and promoted critical thinking and problem solving skills (28%). There were a number of qualitative experiments that were rated 'irrelevant'. Qualitative and quantitative experiments related to recent advances were suggested to be introduced by the respondents. Checklists for the practicals and new curriculum objectives provided in the questionnaire were also approved. The results of the curriculum evaluation suggest a need for re-structuring of practical biochemistry curriculum and introduction of a modified curriculum with more clinical relevance.
Preconditioning for traumatic brain injury
Yokobori, Shoji; Mazzeo, Anna T; Hosein, Khadil; Gajavelli, Shyam; Dietrich, W. Dalton; Bullock, M. Ross
2016-01-01
Traumatic brain injury (TBI) treatment is now focused on the prevention of primary injury and reduction of secondary injury. However, no single effective treatment is available as yet for the mitigation of traumatic brain damage in humans. Both chemical and environmental stresses applied before injury, have been shown to induce consequent protection against post-TBI neuronal death. This concept termed “preconditioning” is achieved by exposure to different pre-injury stressors, to achieve the induction of “tolerance” to the effect of the TBI. However, the precise mechanisms underlying this “tolerance” phenomenon are not fully understood in TBI, and therefore even less information is available about possible indications in clinical TBI patients. In this review we will summarize TBI pathophysiology, and discuss existing animal studies demonstrating the efficacy of preconditioning in diffuse and focal type of TBI. We will also review other non-TBI preconditionng studies, including ischemic, environmental, and chemical preconditioning, which maybe relevant to TBI. To date, no clinical studies exist in this field, and we speculate on possible futureclinical situation, in which pre-TBI preconditioning could be considered. PMID:24323189

The knee is a complex structure afflicted with diverse pathologies. Correct management of knee complaints demands wise utilization of imaging modalities, considering their accuracy in the specific clinical situation, the patient's safety and availability and financial issues. Some of these considerations are universal, while others are local, depending on medical and insurance systems. There is controversy and unclearness regarding the best imaging modality in different clinical situations. To develop clinical guidelines for utilizing knee imaging. Leading physicians in specialties associated with knee disease and imaging were invited to participate in a panel on the guidelines. Controversies were settled in the main panel or in sub-panels. The panel agreed on the principles in choosing from the various modalities, primarily medical accuracy, followed by patient safety, availability and cost. There was agreement that the physician is responsible to choose the most appropriate diagnostic tool, consulting, when necessary, on the advantages, limitations and risks of the various imaging modalities. A comprehensive table was compiled with the importance of the different imaging modalities in various clinical situations. For the first time, Israeli guidelines on wise utilization of knee imaging are presented. They take into consideration the clinical situations and also availability and financial issues specific to Israel. These guidelines will serve physicians of several disciplines and medical insurers to improve patient management efficiently.

Background: Interprofessional collaboration between nurses and physicians is a recurrent challenge in daily clinical practice. To ameliorate the situation, quantitative or qualitative studies are conducted. However, the results of these studies have often been limited by the methods chosen. Aim: To describe the synthesis of interprofessional collaboration from the nursing perspective by triangulating quantitative and qualitative data. Method: Data triangulation was performed as a sub-project of the interprofessional Sinergia DRG Research program. Initially, quantitative and qualitative data were analyzed separately in a mixed methods design. By means of triangulation a „meta-matrix“ resulted in a four-step process. Results: The „meta-matrix“ displays all relevant quantitative and qualitative results as well as their interrelations on one page. Relevance, influencing factors as well as consequences of interprofessional collaboration for patients, relatives and systems become visible. Conclusion: For the first time, the interprofessional collaboration from the nursing perspective at five Swiss hospitals is shown in a „meta-matrix“. The consequences of insufficient collaboration between nurses and physicians are considerable. This is why it’s necessary to invest in interprofessional concepts. In the „meta-matrix“ the factors which influence the interprofessional collaboration positively or negatively are visible.
Learning through participating on an interprofessional training ward.
Lidskog, Marie; Löfmark, Anna; Ahlström, Gerd
2009-09-01
Learning in clinical education can be understood as a process of becoming a legitimate participant in the relevant context. Interprofessional training wards (IPTWs) are designed to give students from educational programmes in health and social care a realistic experience of collaboration for the purpose of developing teamwork skills. IPTWs have been found to be appreciated by the students and to influence students' understanding of each other's professions. The aim of this study was to describe and analyse the students' learning on an interprofessional training ward in care for older persons through focusing on the students' ways of participating in the communities of practice on the ward. A case study design was chosen. Multiple data sources were used. The findings show that the students engaged as active participants in the care. At the same time there was sometimes a discrepancy between on the one hand expectations and goals, on the other hand actual participation. There were difficulties in making the training relevant for all the student groups involved. The findings indicate that in the planning of interprofessional education the choice of setting and learning situations is crucial with regard to the learning that will occur.

Because of the complexity of clinical situations, traditional didactic education is limited in providing opportunity for student-patient interaction. Situated e-learning can enhance learners' knowledge and associated abilities through a variety of activities. Healthcare providers who interact with virtual patients in designed situations may avoid unnecessary risks and encounters with real patients. However, the effectiveness of situated e-learning is inconsistent. The purpose of this study is to determine the effectiveness of situated e-learning in prelicensure and postlicensure medical and nursing education. Literature databases of PubMed, Medline, CINAHL, ERIC, and Cochrane Library were searched. The study eligibility criteria included articles published in English, which examined the effectiveness of situated e-learning on the outcomes of knowledge and performance for clinicians or students in medicine and nursing. Effect sizes were calculated with 95% confidence intervals. Fourteen articles were included for meta-analysis. Situated e-learning could effectively enhance learners' knowledge and performance when the control group received no training. Compared to traditional learning, the effectiveness of situated e-learning on performance diminished but still remained significant whereas the effect become insignificant on knowledge. The subgroup analyses indicate the situated e-learning program significantly improved students' clinical performance but not for clinicians. Situated e-learning is an effective method to improve novice learners' performance. The effect of situated e-learning on the improvement of cognitive ability is limited when compared to traditional learning. Situated e-learning is a useful adjunct to traditional learning for medical and nursing students. © 2013 Sigma Theta Tau International.
[Situational leadership in nursing in a health institution in Bucaramanga, Colombia].
Torres-Contreras, Claudia Consuelo
2013-01-01
In nursing, it is crucial to know the leadership style required in each situation to act as a leader. The clinical nurse must have an effective leadership style that suits the situations presented during the performance of their functions, in order to achieve the objectives in the care of the patient and family. To describe the situational leadership styles present in nurses in hospital departments, including intensive care, according to the theory of Hersey and Blanchard and to determine the relationship between leadership styles and occupational variables. A cross-sectional descriptive study was conducted on a sample population of 107nurses working in clinical areas of hospital and intensive care in two health institutions. The Dr. Herman Bachenheimer situational leadership tool was applied to nursing staff. The nurses at the hospital area (61) and intensive care (46) have mainly a guide-leadership style (35.4%), followed by a participative style (33.9%) and manager-style (27.9%). Delegation leadership style (2.8%) was not present in clinical nurses. There is no significant relationship between leadership styles and the time working in the institution. A statistically significant relationship was found between leadership styles and length of management experience in the clinical area (P=.011). The predominant leadership style of hospital nurses is to guide, and for intensive care nurses it is participatory. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Explore the perceptions of nurses working in mental health of effective clinical leadership. In-depth interviews were conducted with registered nurses employed in a mental health setting. Qualitative research using grounded theory. Remaining calm and confident in times of crisis and uncertainty was identified as one attribute of clinical leadership. Participants noted clinical leaders' demeanor during stressful or crisis situations, and their ability to manage unpredictable or unexpected clinical situations as contributing positively to clinical practice. Understanding these characteristics and how they can influence positive outcomes for clients is crucial in addressing the recruitment and retention challenges for the nursing workforce. © 2014 Wiley Periodicals, Inc.
Clinical implementation of pharmacogenetics.

2016-03-01
In the last decade, pharmacogenetic research has been performed in different fields. However, the application of pharmacogenetic findings to clinical practice has not been as fast as desirable. The current situation of clinical implementation of pharmacogenetics is discussed. This review focuses on the advances of pharmacogenomics to individualize cancer treatments, the relationship between pharmacogenetics and pharmacodynamics in the clinical course of transplant patients receiving a combination of immunosuppressive therapy, the needs and barriers facing pharmacogenetic clinical application, and the situation of pharmacogenetic testing in Spain. It is based on lectures presented by speakers of the Clinical Implementation of Pharmacogenetics Symposium at the VII Conference of the Spanish Pharmacogenetics and Pharmacogenomics Society, held in April 20, 2015.
Defining and assessing professional competence.
Epstein, Ronald M; Hundert, Edward M
2002-01-09
Current assessment formats for physicians and trainees reliably test core knowledge and basic skills. However, they may underemphasize some important domains of professional medical practice, including interpersonal skills, lifelong learning, professionalism, and integration of core knowledge into clinical practice. To propose a definition of professional competence, to review current means for assessing it, and to suggest new approaches to assessment. We searched the MEDLINE database from 1966 to 2001 and reference lists of relevant articles for English-language studies of reliability or validity of measures of competence of physicians, medical students, and residents. We excluded articles of a purely descriptive nature, duplicate reports, reviews, and opinions and position statements, which yielded 195 relevant citations. Data were abstracted by 1 of us (R.M.E.). Quality criteria for inclusion were broad, given the heterogeneity of interventions, complexity of outcome measures, and paucity of randomized or longitudinal study designs. We generated an inclusive definition of competence: the habitual and judicious use of communication, knowledge, technical skills, clinical reasoning, emotions, values, and reflection in daily practice for the benefit of the individual and the community being served. Aside from protecting the public and limiting access to advanced training, assessments should foster habits of learning and self-reflection and drive institutional change. Subjective, multiple-choice, and standardized patient assessments, although reliable, underemphasize important domains of professional competence: integration of knowledge and skills, context of care, information management, teamwork, health systems, and patient-physician relationships. Few assessments observe trainees in real-life situations, incorporate the perspectives of peers and patients, or use measures that predict clinical outcomes. In addition to assessments of basic skills, new formats that assess clinical reasoning, expert judgment, management of ambiguity, professionalism, time management, learning strategies, and teamwork promise a multidimensional assessment while maintaining adequate reliability and validity. Institutional support, reflection, and mentoring must accompany the development of assessment programs.

This report provides guidance on the application of the ICRP system of radiological protection to prolonged exposure situations affecting members of the public. It addresses the general application of the Commission's system to the control of prolonged exposures resulting from practices and to the undertaking of interventions in prolonged exposure situations. Additionally, it provides recommendations on generic reference levels for such interventions. The report also considers some specific situations and discusses a number of issues that have been of concern, namely: natural radiation sources that may give rise to high doses; the restoration and rehabilitation of sites where human activities involving radioactive substances have been carried out; the return to 'normality' following an accident that has released radioactive substances to the environment; and the global marketing of commodities for public consumption that contain radioactive substances. Annexes provide some examples of prolonged exposure situations and discuss the radiological protection quantities, radiation-induced health effects and aspects of the Commission's system of radiological protection relevant to prolonged exposure. Quantitative recommendations for prolonged exposures are provided in the report. They must be interpreted with extreme caution; Chapters 4 and 5 stress the upper bound nature of the following values: Generic reference levels for intervention, in terms of existing total annual doses, are given as < approximately 100 mSv, above which intervention is almost always justifiable (situations for which the annual dose threshold for deterministic effects in relevant organs is exceeded will almost always require intervention), and < approximately 10 mSv, below which intervention is not likely to be justifiable (and above which it may be necessary). Intervention exemption levels for commodities, especially building materials, are expressed as an additional annual dose of approximately 1 mSv. The dose limit for exposures of the public from practices is expressed as aggregated (prolonged and transitory) additional annual doses from all relevant practices of 1 mSv. Dose constraints for sources within practices are expressed as an additional annual dose lower than 1 mSv (e.g. of approximately 0.3 mSv), which could be approximately 0.1 mSv for the prolonged exposure component. An exemption level for practices is expressed as an additional annual dose of approximately 0.01 mSv.

The atmospheric state, aircraft emissions, and engine properties determine formation and initial properties of contrails. The synoptic situation controls microphysical and dynamical processes and causes a wide variability of contrail cirrus life cycles. A reduction of soot particle number emissions, resulting, for example, from the use of alternative fuels, strongly impacts initial ice crystal numbers and microphysical process rates of contrail cirrus. We use the European Centre/Hamburg (ECHAM) climate model version 5 including a contrail cirrus modul, studying process rates, properties, and life cycles of contrail cirrus clusters within different synoptic situations. The impact of reduced soot number emissions is approximated by a reduction in the initial ice crystal number, exemplarily studied for 80%. Contrail cirrus microphysical and macrophysical properties can depend much more strongly on the synoptic situation than on the initial ice crystal number. They can attain a large cover, optical depth, and ice water content in long-lived and large-scale ice-supersaturated areas, making them particularly climate-relevant. In those synoptic situations, the accumulated ice crystal loss due to sedimentation is increased by around 15% and the volume of contrail cirrus, exceeding an optical depth of 0.02, and their short-wave radiative impact are strongly decreased due to reduced soot emissions. These reductions are of little consequence in short-lived and small-scale ice-supersaturated areas, where contrail cirrus stay optically very thin and attain a low cover. The synoptic situations in which long-lived and climate-relevant contrail cirrus clusters can be found over the eastern U.S. occur in around 25% of cases.

Context specificity, or the variation in a participant's performance from one case, or situation, to the next, is a recognized problem in medical education. However, studies have not explored the potential reasons for context specificity in experts using the lens of situated cognition and cognitive load theories (CLT). Using these theories, we…

Whereas direct relationships between 2D:4D and dominance related attitudes or behavior often turn out to be weak, some literature suggests that the relation between 2D:4D and dominance is context-specific. That is, especially in status-challenging situations 2D:4D may be related to dominant behavior and its correlates. Based on this perspective, we interpret inconsistencies in the literature on the relation between 2D:4D and risk taking, aggression and dominance related outcomes and investigate in our empirical study how attitudes in low 2D:4D men may change as a function of the status relevance of the context. We provide evidence for the idea that status relevance of the particular situation at hand influences the attitude towards performance-enhancing means for low 2D:4D men, but not for high 2D:4D men. We argue that 2D:4D may be related to any behavior that is functional to attain status in a specific context. Implications for (economic) decision making are discussed. PMID:29403365

Evaluating alternatives and comparing them to each other are integral to decision-making. In addition, however, decision makers may adopt a view that goes beyond choice and make inferences about the entire set of alternatives, about the dimensions that are relevant in similar decisions, and about the range of values on a specific dimension. We examined some antecedents and consequences of adopting a beyond-choice view of decision situations. Based on Construal Level Theory we suggest that a beyond-choice view entails high (vs. low) level of construal of the decision situation and hence is more likely to occur for decisions that are more psychologically distant. We further suggest that a consequence of a beyond-choice view might be a later difficulty to remember which attribute belongs to which alternative. To examine these predictions we conducted an experiment in which participants evaluated decision scenarios that were described as being relevant for the distant (vs. the near) future. One day later they answered a decision-related source recognition test in which they were asked to remember which attribute belongs to which alternative. As predicted, people had more source-memory errors in the distant than in the near future condition. These results suggest that a beyond-choice view of decision situations is an important consequence of psychological distance (vs. proximity). Copyright © 2016 Elsevier B.V. All rights reserved.

Introduction Syndromic surveillance aims at augmenting traditional public health surveillance with timely information. To gain a head start, it mainly analyses existing data such as from web searches or patient records. Despite the setup of many syndromic surveillance systems, there is still much doubt about the benefit of the approach. There are diverse interactions between performance indicators such as timeliness and various system characteristics. This makes the performance assessment of syndromic surveillance systems a complex endeavour. We assessed if the comparison of several syndromic surveillance systems through Qualitative Comparative Analysis helps to evaluate performance and identify key success factors. Materials and Methods We compiled case-based, mixed data on performance and characteristics of 19 syndromic surveillance systems in Europe from scientific and grey literature and from site visits. We identified success factors by applying crisp-set Qualitative Comparative Analysis. We focused on two main areas of syndromic surveillance application: seasonal influenza surveillance and situational awareness during different types of potentially health threatening events. Results We found that syndromic surveillance systems might detect the onset or peak of seasonal influenza earlier if they analyse non-clinical data sources. Timely situational awareness during different types of events is supported by an automated syndromic surveillance system capable of analysing multiple syndromes. To our surprise, the analysis of multiple data sources was no key success factor for situational awareness. Conclusions We suggest to consider these key success factors when designing or further developing syndromic surveillance systems. Qualitative Comparative Analysis helped interpreting complex, mixed data on small-N cases and resulted in concrete and practically relevant findings. PMID:27182731

Mobile phone interference with medical equipment and its clinical relevance: a systematic review.
Lawrentschuk, Nathan; Bolton, Damien M
2004-08-02
To conduct a systematic review of studies on clinically relevant digital mobile phone electromagnetic interference with medical equipment. MEDLINE and SUMSEARCH were searched for the period 1966-2004. The Cochrane Library and Database of Abstracts of Reviews of Effects were also searched for systematic reviews. Studies were eligible if published in a peer-reviewed journal in English, and if they included testing of digital mobile phones for clinically relevant interference with medical equipment used to monitor or treat patients, but not implantable medical devices. As there was considerable heterogeneity in medical equipment studied and the conduct of testing, results were summarised rather than subjected to meta-analysis. Clinically relevant electromagnetic interference (EMI) secondary to mobile phones potentially endangering patients occurred in 45 of 479 devices tested at 900 MHz and 14 of 457 devices tested at 1800 MHz. However, in the largest studies, the prevalence of clinically relevant EMI was low. Most clinically relevant EMI occurred when mobile phones were used within 1 m of medical equipment. Although testing was not standardised between studies and equipment tested was not identical, it is of concern that at least 4% of devices tested in any study were susceptible to clinically relevant EMI. All studies recommend some type of restriction of mobile phone use in hospitals, with use greater than 1 m from equipment and restrictions in clinical areas being the most common.

The communicative quality of media weather reports, especially warnings, can be evaluated by user research. It is an interdisciplinary field, still uncoordinated after 35 years. The authors suggest to shift from a cognitive learning model to news processing, qualitative discourse and usability models as the media audience is in an edutainment situation where it acts highly selective. A series of field surveys 2008-2011 tested the relevance and legibility of Austrian radio and television weather reports on fair weather and in warning situations. 247 laypeople heard/saw original, mostly up-to-date radio/TV weather reports and recalled personally relevant data. Also, a questionnaire on weather knowledge was answered by 237 Austrians. Several research hypotheses were tested. The main results were (a) a relatively high level of meteorological knowledge of the general population, with interest and participation of German-speaking migrants, (b) a pluralistic media usage with TV, radio and internet as the leading media, (c) higher interest and attention (also for local weather) after warnings, but a risk of more false recalls after long warnings, (d) more recall problems with radio messages and a wish that the weather elements should always appear in the same order to faciliate processing for the audience. In their narrow time windows, radio/TV weather reports should concentrate on main features (synoptic situation, tomorrow's temperature and precipitation, possible warnings), keep a verbal “speed limit” and restrict show elements to serve the active, selective, multioptional, multicultural audience.

Every year in the EU about 800 drivers die in road accidents. In Italy the average is around 200 deaths per year. Based on this context the Occupational Medicine Department (OMD) of Bergamo Hospital has sponsored a new project dedicated to the healthcare and safety of all employees of road haulage in the province of Bergamo. Furthermore the collaboration between UMD and the Clinical Psychology Department of the hospital has allowed the fulfillment of another project aiming to evaluate the personality profile of around 80 drivers employed in the road haulage sector". The aims of the projects is to identify and to point out dangerous situations of significant psychological vulnerability; to know the current situation and to discriminate stress factors from protective ones; to make companies more aware of prevention activities; to inform the drivers about their companies' policy in order to grant safety in their job. The psychological tools used were: half open interview and Personality Inventory MMPI2. The population was selected randomly from volunteers. Now we know the results in 33 tested drivers. So far seven cases have been classified as psychological vulnerable and stress and protective factors have been identified. Results underline the relevance of an integrated approach able to take care of the employees and involving the companies in the prevention programs.

The data model developed on behalf of the Nursing Service Commission of the Canton of Zurich (Pflegedienstkommission des Kantons Zürich) is based on the NANDA nursing diagnoses, the Nursing Outcome Classification, and the Nursing Intervention Classification (NNN Classifications). It also includes integrated functions for cost-centered accounting, service recording, and the Swiss Nursing Minimum Data Set. The data model uses the NNN classifications to map a possible form of the nursing process in the electronic patient health record, where the nurse can choose nursing diagnoses, outcomes, and interventions relevant to the patient situation. The nurses' choice is guided both by the different classifications and their linkages, and the use of specific text components pre-defined for each classification and accessible through the respective linkages. This article describes the developed data model and illustrates its clinical application in a specific patient's situation. Preparatory work required for the implementation of NNN classifications in practical nursing such as content filtering and the creation of linkages between the NNN classifications are described. Against the background of documentation of the nursing process based on the DAPEP(1) data model, possible changes and requirements are deduced. The article provides a contribution to the discussion of a change in documentation of the nursing process by implementing nursing classifications in electronic patient records.

Social anxiety occurs in a range of social situations, the salience of which is influenced by prevailing modes of social contact. The emergence of computer mediated communication (CMC), buoyed by the recent explosion of social networks, has changed the way many people make and maintain social contacts. We randomly assigned 30 socially anxious and 30 low social anxiety participants to a brief internet chat introduction or a control internet surfing condition followed by a standardized face to face (FTF) interaction. We hypothesized that for socially anxious participants the chat introduction would reduce anxiety of and preference to avoid the subsequent FTF interaction. Results supported hypotheses for most indices. Findings suggest that, at least for the common situation in which internet chat precedes FTF interaction with the same person, such contact may reduce social anxiety. It is not known whether this decrease would generalize to FTF contact in other contexts. It is suggested that CMC might be construed as a particularly useful form of safety behavior that may help in the allocation of attentional resources to process new information relevant for disconfirmation of negative beliefs maintaining social anxiety. Potential clinical implications are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

To identify challenging interpersonal interactions experienced by nursing and pharmacy students during clinical placement, and strategies used to manage those situations. Healthcare students and staff experience elevated stress when exposed to dynamic clinical environments, complex care and challenging professional relationships. Emotionally intelligent behaviours are associated with appropriate recognition and management of emotions evoked by stressful experiences and development of effective relationships. Nursing and pharmacy students' use of emotionally intelligent behaviours to manage challenging interpersonal situations is not well known. A qualitative design, using semi-structured interviews to explore experiences of challenging interpersonal situations during clinical placement (Phase two of a larger mixed-methods study). Final-year Australian university nursing and pharmacy students (n = 20) were purposefully recruited using a range of Emotional Intelligence scores (derived in Phase one), measured using the GENOS Emotional intelligence Inventory (concise version). Challenging interpersonal situations involving student-staff and intrastaff conflict, discourteous behaviour and criticism occurred during clinical placement. Students used personal and relational strategies, incorporating emotionally intelligent behaviours, to manage these encounters. Strategies included reflecting and reframing, being calm, controlling discomfort and expressing emotions appropriately. Emotionally intelligent behaviours are effective to manage stressful interpersonal interactions. Methods for strengthening these behaviours should be integrated into education of nursing and pharmacy students and qualified professionals. Education within the clinical/workplace environment can incorporate key interpersonal skills of collaboration, social interaction and reflection, while also attending to sociocultural contexts of the healthcare setting. Students and staff are frequently exposed to stressful clinical environments and challenging interpersonal encounters within healthcare settings. Use of emotionally intelligent behaviours to recognise and effectively manage these encounters may contribute to greater stress tolerance and enhanced professional relationships. Nursing and pharmacy students, and their qualified counterparts, need to be educated to strengthen their emotional intelligence skills. © 2017 John Wiley & Sons Ltd.

Jaundice is a common and complex clinical symptom potentially occurring in hepatology, general surgery, pediatrics, infectious diseases, gynecology, and obstetrics, and it is fairly difficult to distinguish the cause of jaundice in clinical practice, especially for general practitioners in less developed regions. With collaboration between physicians and artificial intelligence engineers, a comprehensive knowledge base relevant to jaundice was created based on demographic information, symptoms, physical signs, laboratory tests, imaging diagnosis, medical histories, and risk factors. Then a diagnostic modeling and reasoning system using the dynamic uncertain causality graph was proposed. A modularized modeling scheme was presented to reduce the complexity of model construction, providing multiple perspectives and arbitrary granularity for disease causality representations. A "chaining" inference algorithm and weighted logic operation mechanism were employed to guarantee the exactness and efficiency of diagnostic reasoning under situations of incomplete and uncertain information. Moreover, the causal interactions among diseases and symptoms intuitively demonstrated the reasoning process in a graphical manner. Verification was performed using 203 randomly pooled clinical cases, and the accuracy was 99.01% and 84.73%, respectively, with or without laboratory tests in the model. The solutions were more explicable and convincing than common methods such as Bayesian Networks, further increasing the objectivity of clinical decision-making. The promising results indicated that our model could be potentially used in intelligent diagnosis and help decrease public health expenditure.

The purpose of this study was to analyze characteristics of individuals working in the profession of neuropsychology in Latin America in order to understand their background, professional training, current work situation, assessment and diagnostic procedures used, rehabilitation techniques employed, population targeted, teaching responsibilities, and research activities. A total of 808 professionals working in neuropsychology from 17 countries in Latin America completed an online survey between July 2013 and January 2014. The majority of participants were female and the mean age was 36.76 years (range 21-74 years). The majority of professionals working in neuropsychology in Latin America have a background in psychology, with some additional specialized training and supervised clinical practice. Over half work in private practice, universities, or private clinics and are quite satisfied with their work. Those who identify themselves as clinicians primarily work with individuals with learning problems, ADHD, mental retardation, TBI, dementia, and stroke. The majority respondents cite the top barrier in the use of neuropsychological instruments to be the lack of normative data for their countries. The top perceived barriers to the field include: lack of academic training programs, lack of clinical training opportunities, lack of willingness to collaborate between professionals, and lack of access to neuropsychological instruments. There is a need in Latin America to increase regulation, improve graduate curriculums, enhance existing clinical training, develop professional certification programs, validate existing neuropsychological tests, and create new, culturally-relevant instruments.

Methods were invented that made it possible to image peripheral nerves in the body and to image neural tracts in the brain. The history, physical basis, and dyadic tensor concept underlying the methods are reviewed. Over a 15-year period, these techniques-magnetic resonance neurography (MRN) and diffusion tensor imaging-were deployed in the clinical and research community in more than 2500 published research reports and applied to approximately 50,000 patients. Within this group, approximately 5000 patients having MRN were carefully tracked on a prospective basis. A uniform Neurography imaging methodology was applied in the study group, and all images were reviewed and registered by referral source, clinical indication, efficacy of imaging, and quality. Various classes of image findings were identified and subjected to a variety of small targeted prospective outcome studies. Those findings demonstrated to be clinically significant were then tracked in the larger clinical volume data set. MRN demonstrates mechanical distortion of nerves, hyperintensity consistent with nerve irritation, nerve swelling, discontinuity, relations of nerves to masses, and image features revealing distortion of nerves at entrapment points. These findings are often clinically relevant and warrant full consideration in the diagnostic process. They result in specific pathological diagnoses that are comparable to electrodiagnostic testing in clinical efficacy. A review of clinical outcome studies with diffusion tensor imaging also shows convincing utility. MRN and diffusion tensor imaging neural tract imaging have been validated as indispensable clinical diagnostic methods that provide reliable anatomic pathological information. There is no alternative diagnostic method in many situations. With the elapsing of 15 years, tens of thousands of imaging studies, and thousands of publications, these methods should no longer be considered experimental.

Prevalence of new diseases, medical science promotion and increase of referring to health care centers, provide a good situation for medical errors growth. Errors can involve medicines, surgery, diagnosis, equipment, or lab reports. Medical errors can occur anywhere in the health care system: In hospitals, clinics, surgery centers, doctors' offices, nursing homes, pharmacies, and patients' homes. According to the Institute of Medicine (IOM), 98,000 people die every year from preventable medical errors. In 2010 from all referred medical error records to Iran Legal Medicine Organization, 46/5% physician and medical team members were known as delinquent. One of new technologies that can reduce medical errors is clinical decision support systems (CDSSs). This study was unsystematic-review study. The literature was searched on evaluate the "ability of clinical decision support systems to improve clinical practice" with the help of library, books, conference proceedings, data bank, and also searches engines available at Google, Google scholar. For our searches, we employed the following keywords and their combinations: medical error, clinical decision support systems, Computer-Based Clinical Decision Support Systems, information technology, information system, health care quality, computer systems in the searching areas of title, keywords, abstract, and full text. In this study, more than 100 articles and reports were collected and 38 of them were selected based on their relevancy. The CDSSs are computer programs, designed for help to health care careers. These systems as a knowledge-based tool could help health care manager in analyze evaluation, improvement and selection of effective solutions in clinical decisions. Therefore, it has a main role in medical errors reduction. The aim of this study was to express ability of the CDSSs to improve
The clinical educator and complexity: a review.
Schoo, Adrian; Kumar, Koshila
2018-02-08
Complexity science perspectives have helped in examining fundamental assumptions about learning and teaching in the health professions. The implications of complexity thinking for how we understand the role and development of the clinical educator is less well articulated. This review article outlines: the key principles of complexity science; a conceptual model that situates the clinical educator in a complex system; and the implications for the individual, organisation and the system. Our conceptual model situates the clinical educator at the centre of a complex and dynamic system spanning four domains and multiple levels. The four domains are: personal (encompassing personal/professional needs and expectations); health services (health agencies and their consumers); educational (educational institutions and their health students); and societal (local community/region and government). The system also comprises: micro or individual, meso or organisational, and macro or socio-political levels. Our model highlights that clinical educators are situated within a complex system comprising different agents and connections. It emphasises that individuals, teams and organisations need to recognise and be responsive to the unpredictability, interconnectedness and evolving nature of this system. Importantly, our article also calls for an epistemological shift from faculty development to capacity building in health professions education, aimed at developing individual, team, organisational and system capabilities to work with(in) complexity. Clinical educators are situated within a complex system comprising different agents and connections. © 2018 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Despite increasingly diverse, globalized societies, little attention has been paid to the influence of religious and spiritual diversity on clinical encounters within healthcare. The purpose of the study was to analyze the negotiation of religious and spiritual plurality in clinical encounters, and the social, gendered, cultural, historical, economic and political contexts that shape that negotiation. Qualitative: critical ethnography. The study was conducted in Western Canada between 2006 and 2009. Data collection occurred on palliative, hospice, medical and renal in-patient units at two tertiary level hospitals and seven community hospitals. Participants were recruited through purposive sampling and snowball technique. Twenty healthcare professionals, seventeen spiritual care providers, sixteen patients and families and twelve administrators, representing diverse ethnicities and religious affiliations, took part in the study. Data collection included 65 in-depth interviews and over 150h of participant observation. Clinical encounters between care providers and recipients were shaped by how individual identities in relation to religion and spirituality were constructed. Importantly, these identities did not occur in isolation from other lines of social classification such as gender, race, and class. Negotiating difference was a process of seeing spirituality as a point of connection, eliciting the meaning systems of patients and creating safe spaces for the expression of that meaning. The complexity of religious and spiritual identity construction and negotiation raises important questions about language and about professional competence and boundaries in clinical encounters where religion and spirituality are relevant concerns.

Querying temporal clinical databases on granular trends.
Combi, Carlo; Pozzi, Giuseppe; Rossato, Rosalba
2012-04-01
This paper focuses on the identification of temporal trends involving different granularities in clinical databases, where data are temporal in nature: for example, while follow-up visit data are usually stored at the granularity of working days, queries on these data could require to consider trends either at the granularity of months ("find patients who had an increase of systolic blood pressure within a single month") or at the granularity of weeks ("find patients who had steady states of diastolic blood pressure for more than 3 weeks"). Representing and reasoning properly on temporal clinical data at different granularities are important both to guarantee the efficacy and the quality of care processes and to detect emergency situations. Temporal sequences of data acquired during a care process provide a significant source of information not only to search for a particular value or an event at a specific time, but also to detect some clinically-relevant patterns for temporal data. We propose a general framework for the description and management of temporal trends by considering specific temporal features with respect to the chosen time granularity. Temporal aspects of data are considered within temporal relational databases, first formally by using a temporal extension of the relational calculus, and then by showing how to map these relational expressions to plain SQL queries. Throughout the paper we consider the clinical domain of hemodialysis, where several parameters are periodically sampled during every session. Copyright © 2011 Elsevier Inc. All rights reserved.
Impact of stress on dentists' clinical performance. A systematic review.
Plessas, A; Delgado, M B; Nasser, M; Hanoch, Y; Moles, D R
2018-03-01
Dentistry is recognised as a stressful profession and dentists perceive their profession to be more stressful than other healthcare professions. While earlier studies have shown a link between stress and well-being among dentists, whether stress negatively impacts their clinical performance is an important and open question. We do know, however, that stress is associated with reduced performance in other health (and non-health) related professions. This systematic review aimed to answer the question: how does stress impact on dentists' clinical performance? This systematic review was registered in PROSPERO (CRD42016045756). The CINHAL, Embase, Medline, PsycINFO, EThOS and OpenGrey electronic databases were searched according to PRISMA guidelines. Two reviewers independently screened the citations for relevance. The citation list of potentially eligible papers was also searched. Prospective empirical studies were considered for inclusion. The inclusion criteria were applied at the full-text stage by the two same reviewers independently. The search yielded 3535 titles and abstracts. Twelve publications were considered potentially eligible, eleven of which were excluded as they did not meet the predefined inclusion criteria. This systematic review identified a gap in the literature as it found no empirical evidence quantifying the impact of stress on dentists' clinical performance. Prospective well-designed experimental simulation studies, comparing stress with non-stress situations on clinical performance and decision making, as well studies evaluating prospectively real-life dentists' performance under stress are warranted.

Clinical Performance of a New Biomimetic Double Network Material
Dirxen, Christine; Blunck, Uwe; Preissner, Saskia
2013-01-01
Background: The development of ceramics during the last years was overwhelming. However, the focus was laid on the hardness and the strength of the restorative materials, resulting in high antagonistic tooth wear. This is critical for patients with bruxism. Objectives: The purpose of this study was to evaluate the clinical performance of the new double hybrid material for non-invasive treatment approaches. Material and Methods: The new approach of the material tested, was to modify ceramics to create a biomimetic material that has similar physical properties like dentin and enamel and is still as strong as conventional ceramics. Results: The produced crowns had a thickness ranging from 0.5 to 1.5 mm. To evaluate the clinical performance and durability of the crowns, the patient was examined half a year later. The crowns were still intact and soft tissues appeared healthy and this was achieved without any loss of tooth structure. Conclusions: The material can be milled to thin layers, but is still strong enough to prevent cracks which are stopped by the interpenetrating polymer within the network. Depending on the clinical situation, minimally- up to non-invasive restorations can be milled. Clinical Relevance: Dentistry aims in preservation of tooth structure. Patients suffering from loss of tooth structure (dental erosion, Amelogenesis imperfecta) or even young patients could benefit from minimally-invasive crowns. Due to a Vickers hardness between dentin and enamel, antagonistic tooth wear is very low. This might be interesting for treating patients with bruxism. PMID:24167534
[Economic analysis of multinational clinical trials in oncology].
Lejeune, Catherine; Lueza, Béranger; Bonastre, Julia
2018-02-01
In oncology, as in other fields of medicine, international multicentre clinical trials came into being so as to include a sufficient number of subjects to investigate a clinical situation. The existence of tight budgetary constraints and the desire to make the best use of the resources available have resulted in the development of economic evaluations associated with these trials, which, thanks to their level of evidence and their size, provide particularly relevant material. Nonetheless, economic evaluations alongside international clinical trials raise specific questions of methodology with regard to both the design and the analysis of the results. Indeed, the costs of goods and services consumed, the types and quantities of resources, and medical practices vary from one country to another and within an individual country. Economic data from the different countries involved must be available so as to study and to take into account this variability, and appropriate techniques for cost estimations and analysis must be implemented to aggregate the results from several countries. From a review of the literature, the aim of this work was to provide an overview of the specific methodological features of economic evaluations alongside international clinical trials: analysis of efficacy data from several countries, collection of resources and real costs, methods to establish the monetary value of resources, methods to aggregate results accounting for the trial effect.

Very little has been written on seizure management in palliative care (PC). Given this situation, and considering the forthcoming setting up of the Palliative Care Unit at our neurorehabilitation centre, the Clínica San Vicente, we decided to establish a series of guidelines on the use of antiepileptic drugs (AEDs) for handling seizures in PC. We conducted a literature search in PubMed to identify articles, recent manuals, and clinical practice guidelines on seizure management in PC published by the most relevant scientific societies. Clinical practice guidelines are essential to identify patients eligible for PC, manage seizures adequately, and avoid unnecessary distress to these patients and their families. Given the profile of these patients, we recommend choosing AEDs with a low interaction potential and which can be administered by the parenteral route, preferably intravenously. Diazepam and midazolam appear to be the most suitable AEDs during the acute phase whereas levetiracetam, valproic acid, and lacosamide are recommended for refractory cases and long-term treatment. These guidelines provide general recommendations that must be adapted to each particular clinical case. Nevertheless, we will require further well-designed randomised controlled clinical trials including large samples of patients eligible for PC to draft a consensus document recommending adequate, rational, and effective use of AEDs, based on a high level of evidence, in this highly complex area of medical care.

Cognitive behavioural therapy (CBT) is beneficial in depression. Symptom scores can be translated into Clinical Global Impression (CGI) scale scores to indicate clinical relevance. We aimed to assess the clinical relevance of findings of randomised controlled trials (RCTs) of CBT in depression. We identified RCTs of CBT that used the Hamilton Rating Scale for Depression (HAMD). HAMD scores were translated into Clinical Global Impression - Change scale (CGI-I) scores to measure clinical relevance. One hundred and seventy datasets from 82 studies were included. The mean percentage HAMD change for treatment arms was 53.66%, and 29.81% for control arms, a statistically significant difference. Combined active therapies showed the biggest improvement on CGI-I score, followed by CBT alone. All active treatments had better than expected HAMD percentage reduction and CGI-I scores. CBT has a clinically relevant effect in depression, with a notional CGI-I score of 2.2, indicating a significant clinical response. The non-specific or placebo effect of being in a psychotherapy trial was a 29% reduction of HAMD. Copyright © 2017. Published by Elsevier Masson SAS.

In this prospective study of 135 patients undergoing cementless total hip arthroplasty (THA) we asked whether six current definitions of combined anteversion prevent impingement and increase postoperative patient individual impingement-free range-of-motion (ROM). Implant position was measured by an independent, external institute on 3D-CT performed six weeks post-operatively. Post-operative ROM was calculated using a CT-based algorithm detecting osseous and/or prosthetic impingement by virtual hip movement. Additionally, clinical ROM was evaluated pre-operatively and one-year post-operatively by a blinded observer. Combined component position of cup and stem according to the definitions of Ranawat, Widmer, Dorr, Hisatome and Yoshimine inhibited prosthetic impingement in over 90 %, while combined osseous and prosthetic impingement still occurred in over 40 % of the cases. The recommendations by Jolles, Widmer, Dorr, Yoshimine and Hisatome enabled higher flexion (p ≤ 0.001) and internal rotation (p ≤ 0.006). Clinically, anteversion rules of Widmer and Yoshimine provided one-year post-operatively statistically but not clinically relevant higher internal rotation (p ≤0.034). Standard rules of combined anteversion detect prosthetic but fail to prevent combined osseous and prosthetic impingement in THA. Future models will have to account for the patient-individual anatomic situation to ensure impingement-free ROM.

Recently published data suggest that artemisinin derivatives and synthetic peroxides, such as the ozonides OZ277 and OZ439, have a similar mode of action. Here the cross-resistance of OZ277 and OZ439 and four additional next-generation ozonides was probed against the artemisinin-resistant clinical isolate Plasmodium falciparum Cam3.I, which carries the K13-propeller mutation R539T (Cam3.I R539T ). The previously described in vitro ring-stage survival assay (RSA 0-3h ) was employed and a simplified variation of the original protocol was developed. At the pharmacologically relevant concentration of 700 nM, all six ozonides were highly effective against the dihydroartemisinin-resistant P. falciparum Cam3.I R539T parasites, showing a per cent survival ranging from <0.01 to 1.83%. A simplified version of the original RSA 0-3h method was developed and gave similar results, thus providing a practical drug discovery tool for further optimization of next-generation anti-malarial peroxides. The absence of in vitro cross-resistance against the artemisinin-resistant clinical isolate Cam3.I R539T suggests that ozonides could be effective against artemisinin-resistant P. falciparum. How this will translate to the human situation in clinical settings remains to be investigated.

A testosterone-lowering medication is relatively commonly used as a form of treatment for sexual offenders with severe paraphilic disorders in German forensic psychiatric hospitals; however, a double-blind, controlled and randomized study, which investigates the efficacy of this medication, is still lacking. This article describes the process from the planning to the rejection of a clinical trial over the period from 2009 to 2015. Despite the careful planning with an interdisciplinary team and giving special consideration to the complex legal situation, the Federal Institute for Drugs and Medical Devices (BfArM) rejected the proposed trial in a brief formal letter with reference to the German Drug Law (§ 40 para. 1 p. 3 nr. 4 AMG). The ethics committee of the Hamburg Medical Association considered that clinical research is basically not possible with patients detained in a forensic psychiatric hospital. In the opinion of the authors, the described facts illustrate how legal regulations that should protect vulnerable groups in medical research, in a specific case can lead to the fact that a therapy form relevant to the corresponding patient group cannot be scientifically investigated.

A residual risk of morbidity and mortality from cardiovascular (CV) disease remains despite statin therapy. This situation has generated an interest in finding novel approaches of combining statins with other lipid-lowering agents, or finding new lipid and non-lipid targets, such as triglycerides, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, proprotein convertase subtilisin/kexin type 9 (PCSK9) gene, cholesterol ester transfer protein (CETP), lipoprotein (a), fibrinogen or C-reactive protein. The recent results from the IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT) demonstrated an incremental clinical benefit when ezetimibe, a non-statin agent, was added to simvastatin therapy. The results from IMPROVE-IT revalidated the concept that low-density lipoprotein cholesterol (LDL-C) levels are a clinically relevant treatment goal. This trial also suggested that further decrease of LDL-C levels (53 vs. 70 mg/dl; 1.4 vs. 1.8 mmol/l) was more beneficial in lowering CV events. This "even lower is even better" evidence for LDL-C levels may influence future guidelines and the use of new drugs. Furthermore, these findings make ezetimibe a more realistic option to treat patients with statin intolerance or those who cannot achieve LDL-C targets with statin monotherapy.
Gemfibrozil in Combination with Statins-Is It Really Contraindicated?
Wiggins, Barbara S; Saseen, Joseph J; Morris, Pamela B
2016-04-01
Gemfibrozil is a lipid-modifying agent that belongs to the fibric acid derivative class. Fibric acid derivatives activate peroxisome proliferator activated receptor α (PPAR-α). The primary role of these agents in clinical practice is for the management of hypertriglyceridemia. Triglycerides may be reduced by as much as 74 % in some patients. In addition to lowering triglycerides, these agents can also decrease very low-density lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C) as well as raise high-density lipoprotein cholesterol (HDL-C). Based on the 2013 ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults and the National Lipid Association, pharmacologic therapy to reduce triglycerides should be considered when triglyceride levels are ≥500 mg/dL. While the use of gemfibrozil has decreased over the years for a variety of reasons, muscle-associated adverse effects is the predominant reason and the one that is most clinically relevant. However, despite these concerns, there are situations in which the use of gemfibrozil in combination with a statin may be necessary. Understanding the metabolism of gemfibrozil and the degree of interaction with the various statins will assist health-care providers to optimize safety when this combination is clinically indicated.

Objectives: Precision medicine requires the measurement, quantification, and cataloging of medical characteristics to identify the most effective medical intervention. However, the amount of available data exceeds our current capacity to extract meaningful information. We examine the informatics needs to achieve precision medicine from the perspective of quantitative imaging and oncology. Methods: The National Cancer Institute (NCI) organized several workshops on the topic of medical imaging and precision medicine. The observations and recommendations are summarized herein. Results: Recommendations include: use of standards in data collection and clinical correlates to promote interoperability; data sharing and validation of imaging tools; clinician's feedback in all phases of research and development; use of open-source architecture to encourage reproducibility and reusability; use of challenges which simulate real-world situations to incentivize innovation; partnership with industry to facilitate commercialization; and education in academic communities regarding the challenges involved with translation of technology from the research domain to clinical utility and the benefits of doing so. Conclusions: This article provides a survey of the role and priorities for imaging informatics to help advance quantitative imaging in the era of precision medicine. While these recommendations were drawn from oncology, they are relevant and applicable to other clinical domains where imaging aids precision medicine. Georg Thieme Verlag KG Stuttgart.
Drug development in neuropsychopharmacology.
Fritze, Jürgen
2008-03-01
Personalized medicine is still in its infancy concerning drug development in neuropsychopharmacology. Adequate biomarkers with clinical relevance to drug response and/or tolerability and safety largely remain to be identified. Possibly, this kind of personalized medicine will first gain clinical relevance in the dementias. The clinical relevance of the genotyping of drug-metabolizing enzymes as suggested by drug licensing authorities for the pharmacokinetic evaluation of medicinal products needs to be proven in sound clinical trials.

To create a tool to identify drugs and clinical situations that offers an opportunity of deprescribing in patients with multimorbidity. A literature review completed with electronic brainstorming, and subsequently, a panel of experts using the Delphi methodology were applied. The experts assessed the criteria identified in the literature and brainstorming as possible situations for deprescribing. They were also asked to assess the influence of life prognosis in each criterion. A tool was composed of the most appropriate criteria according to the strength of their evidence, usefulness in patients with multimorbidity and applicability in clinical practice. Out of a total of 100, 27 criteria were selected to be included in the final list. It was named the LESS-CHRON criteria (List of Evidence-baSed depreScribing for CHRONic patients), and was organized by the anatomical group of the Anatomical, Therapeutic, Chemical (ATC) classification system of the drug to be deprescribed. Each criterion contains: drug indication for which it is prescribed, clinical situation that offers an opportunity to deprescribe, clinical variable to be monitored and the minimum time to follow up the patient after deprescribing. The "LESS-CHRON criteria" are the result of a comprehensive and standardized methodology to identify clinical situations for deprescribing drugs in chronic patients with multimorbidity.

We could assess the current medical situation in the Pacific Islands through this training course, and also obtain relevant material to analyze appropriate measures deemed necessary to improve the situation.
Neurodynamics in the Sensorimotor Loop: Representing Behavior Relevant External Situations
Pasemann, Frank
2017-01-01
In the context of the dynamical system approach to cognition and supposing that brains or brain-like systems controlling the behavior of autonomous systems are permanently driven by their sensor signals, the paper approaches the question of neurodynamics in the sensorimotor loop in a purely formal way. This is carefully done by addressing the problem in three steps, using the time-discrete dynamics of standard neural networks and a fiber space representation for better clearness. Furthermore, concepts like meta-transients, parametric stability and dynamical forms are introduced, where meta-transients describe the effect of realistic sensor inputs, parametric stability refers to a class of sensor inputs all generating the “same type” of dynamic behavior, and a dynamical form comprises the corresponding class of parametrized dynamical systems. It is argued that dynamical forms are the essential internal representatives of behavior relevant external situations. Consequently, it is suggested that dynamical forms are the basis for a memory of these situations. Finally, based on the observation that not all brain process have a direct effect on the motor activity, a natural splitting of neurodynamics into vertical (internal) and horizontal (effective) parts is introduced.

Evidence based medicine (EBM) is considered an integral part of medical training, but integration of teaching various EBM steps in everyday clinical practice is uncommon. Currently EBM is predominantly taught through theoretical courses, workshops and e-learning. However, clinical teachers lack confidence in teaching EBM in workplace and are often unsure of the existing opportunities for teaching EBM in the clinical setting. There is a need for continuing professional development (CPD) courses that train clinical trainers to teach EBM through on-the-job training by demonstration of applied EBM real time in clinical practice. We developed such a course to encourage clinically relevant teaching of EBM in post-graduate education in various clinical environments. We devised an e-learning course targeting trainers with EBM knowledge to impart educational methods needed to teach application of EBM teaching in commonly used clinical settings. The curriculum development group comprised experienced EBM teachers, clinical epidemiologists, clinicians and educationalists from institutions in seven European countries. The e-learning sessions were designed to allow participants (teachers) to undertake the course in the workplace during short breaks within clinical activities. An independent European steering committee provided input into the process. The curriculum defined specific learning objectives for teaching EBM by exploiting educational opportunities in six different clinical settings. The e-modules incorporated video clips that demonstrate practical and effective methods of EBM teaching in everyday clinical practice. The course encouraged focussed teaching activities embedded within a trainer's personal learning plan and documentation in a CPD portfolio for reflection. This curriculum will help senior clinicians to identify and make the best use of available opportunities in everyday practice in clinical situations to teach various steps of EBM and demonstrate their applicability to clinical practice. Once fully implemented, the ultimate outcome of this pilot project will be a European qualification in teaching EBM, which will be used by doctors, hospitals, professional bodies responsible for postgraduate qualifications and continuing medical education.

The issue of how to support situation awareness among crews of modern commercial aircraft is becoming especially important with the introduction of automation in the form of sophisticated flight management computers and expert systems designed to assist the crew. In this paper, cognitive theories are discussed that have relevance for the definition and measurement of situation awareness. These theories suggest that comprehension of the flow of events is an active process that is limited by the modularity of attention and memory constraints, but can be enhanced by expert knowledge and strategies. Three implications of this perspective for assessing and improving situation awareness are considered: (1) Scenario variations are proposed that tax awareness by placing demands on attention; (2) Experimental tasks and probes are described for assessing the cognitive processes that underlie situation awareness; and (3) The use of computer-based human performance models to augment the measures of situation awareness derived from performance data is explored. Finally, two potential example applications of the proposed assessment techniques are described, one concerning spatial awareness using wide field of view displays and the other emphasizing fault management in aircraft systems.

Undergraduate students can learn how to be innovative in partnerships with health care institutions and private enterprises. This study portrays how a three phase innovation model was applied in an interprofessional health education context at a Danish university college. The aim of the study was to explore midwifery, nutrition and health as well physiotherapy students' perceptions of participating in a real-life innovation project situated in antenatal care. A total of eighteen students participated in five focus group interviews. Thematic analysis was used to interpret data findings. Data analysis revealed three themes: 'Navigating in uncertainty', 'Being part of a team' and 'Impact of project learning'. Students found project learning to be the most relevant with regards to their clinical practice. Furthermore, study findings suggest that innovation is promoted by teamwork, interprofessional participation, mentor support and external partnerships. Copyright © 2015 Elsevier Ltd.

Carcinoma cervix is a common cancer among Indian women. Evidence based management is essential for best practice in treatment of carcinoma cervix for its effective control. The current imaging system like CT, MRI and PET CT scans have contributed in identifying the patients for optimal treatment and delivering treatment accurately. For stages IB2 to IV, concurrent chemoradiation is advocated with improvement in overall survival proven with randomized trials. Brachytherapy is an integral part in the radiation treatment. Imaged-guided brachytherapy using MRI is desirable, however less expensive imaging modalities such as CT and ultrasonography has been evaluated. In special situation such as for HIV positive patients and patients with neuroendocrine tumors have role of radiotherapy. For further improvement in control of cancer, it is required to integrate basic research to answer clinically relevant questions. Copyright © 2018 Elsevier Inc. All rights reserved.
Pharmacoeconomics and macular degeneration.
Brown, Gary C; Brown, Melissa M; Brown, Heidi; Godshalk, Ashlee N
2007-05-01
To describe pharmacoeconomics and its relationship to drug interventions. Pharmacoeconomics is the branch of economics which applies cost-minimization, cost-benefit, cost-effectiveness and cost-utility analyses to compare the economics of different pharmaceutical products or to compare drug therapy to other treatments. Among the four instruments, cost-utility analysis is the most sophisticated, relevant and clinically applicable as it measures the value conferred by drugs for the monies expended. Value-based medicine incorporates cost-utility principles but with strict standardization of all input and output parameters to allow the comparability of analyses, unlike the current situation in the healthcare literature. Pharmacoeconomics is assuming an increasingly important role with regard to whether drugs are listed on the drug formulary of a country or province. It has been estimated that the application of standardized, value-based medicine drug analyses can save over 35% from a public healthcare insurer drug formulary while maintaining or improving patient care.

Cost accounting is performed in private and public laboratories. Guidelines for these activities are required and with this objective in mind, the Board of the Danish Society of Clinical Chemistry commissioned a working group to produce a position paper which is presented now in this report. The report discusses the objectives, the principles and the general requirements for cost accounting. The significance of information on costs for the clinicians' rational use of the laboratory is also illustrated. The working group points out that prerequisites for lucid and appropriate costing guidelines are clarification of which purposes information on costs are meant to serve, identification of the relevant cost centers and quality assurance of laboratory services to a defined extent. It is common practice to express laboratory costs as costs per test. The report advocates calculation of the cost per patient contact, i.e. the overall costs for laboratory service in a given investigative situation.

Measurement of catecholamines derivatives is used to diagnose tumors such as pheochromocytomas and paragangliomas. Despite the low incidence of these diseases, their diagnosis is essential because of potentially lethal episodes of malignant hypertension related to an inappropriate secretion of catecholamines by these tumors. The catecholamines derivatives include 3-methoxytyramine, normetanephrine and metanephrine, assayed in urine or plasma. The significance of the measurement of urinary 3-methoxytyramine was addressed by analysing the records of 28 patients aged 25 to 84 years with isolated elevation of this derivative, with non-pathological urinary rates of metanephrine and normetanephrine, that might help suspect a catecholamine inappropriate secretion. In these situations, no pheochromocytoma or paraganglioma was diagnosed. This study, after discussing possible biases in the clinical care and diagnosis approach of these patients, raises the question of the relevance of this assay in the diagnostic management of these diseases.

Highly active antiretroviral therapy has extended the expected lifespan of patients with HIV/AIDS. However, the therapeutic benefits of some drugs used simultaneously with highly active antiretroviral therapy may be adversely affected by drug interactions. The goal was to design and develop a free software to facilitate analysis, assessment, and clinical decision making according to the clinical relevance of drug interactions in patients with HIV/AIDS. A comprehensive Medline/PubMed database search of drug interactions was performed. Articles that recognized any drug interactions in HIV disease were selected. The publications accessed were limited to human studies in English or Spanish, with full texts retrieved. Drug interactions were analyzed, assessed, and grouped into four levels of clinical relevance according to gravity and probability. Software to systematize the information regarding drug interactions and their clinical relevance was designed and developed. Overall, 952 different references were retrieved and 446 selected; in addition, 67 articles were selected from the citation lists of identified articles. A total of 2119 pairs of drug interactions were identified; of this group, 2006 (94.7%) were drug-drug interactions, 1982 (93.5%) had an identified pharmacokinetic mechanism, and 1409 (66.5%) were mediated by enzyme inhibition. In terms of clinical relevance, 1285 (60.6%) drug interactions were clinically significant in patients with HIV (levels 1 and 2). With this information, a software program that facilitates identification and assessment of the clinical relevance of antiretroviral drug interactions (SIMARV ® ) was developed. A free software package with information on 2119 pairs of antiretroviral drug interactions was designed and developed that could facilitate analysis, assessment, and clinical decision making according to the clinical relevance of drug interactions in patients with HIV/AIDS.

The research was conducted in support of the NASA Safe All-Weather Flight Operations for Rotorcraft (SAFOR) program. The purpose of the work was to investigate the utility of two measurement tools developed by the British Defense Evaluation Research Agency. These tools were a subjective workload assessment scale, the DRA Workload Scale and a situation awareness measurement tool. The situation awareness tool uses a comparison of the crew's self-evaluation of performance against actual performance in order to determine what information the crew attended to during the performance. These two measurement tools were evaluated in the context of a test of innovative approach to alerting the crew by way of a helmet mounted display. The situation assessment data are reported here. The performance self-evaluation metric of situation awareness was found to be highly effective. It was used to evaluate situation awareness on a tank reconnaissance task, a tactical navigation task, and a stylized task used to evaluated handling qualities. Using the self-evaluation metric, it was possible to evaluate situation awareness, without exact knowledge the relevant information in some cases and to identify information to which the crew attended or failed to attend in others.
Rejection or selection: influence of framing in investment decisions.
Cheng, Pi-Yueh; Chiou, Wen-Bin
2010-02-01
According to prospect theory, reflection effects result in preferences for risk-averse choices in gain situations and risk-seeking choices in loss situations. However, relevant literature in regard to decision making has suggested that positive information receives more weight in a selection task, whereas negative information receives more weight in a rejection task. The present study examined whether the nature of a decision task (selection vs rejection) would moderate the reflection effects. Undergraduates (47 men, 49 women; M age = 20.5 yr., SD = 1.1), selected according to specific screening criteria, participated in an experimental study. Typical reflection effects were observed in both selection and rejection task conditions. More importantly, negative information (i.e., the information about probable loss in risky choice of gain situations and the information about certain loss in cautious choice of loss situations) provided in the context of a rejection task received more weight and resulted in more frequent endorsements of the cautious choice in gain situations and of the risky choice in loss situations. Hence, the findings suggest that a decision context characterized by rejection may expand the reflection effects and thereby provide important information about situations in which investment decisions occur in a context characterized by rejection.

The article addresses the history of evidence-based medicine in Germany. Its aim was to reconstruct the standard of clinical-therapeutic investigation in Germany at the beginning of the 20 (th) century. By a historical investigation of five important German general medical journals for the time between 1918 and 1932 an overview of the situation of clinical investigation is given. 268 clinical trails are identified, and are analysed in view of their methodological design. Heterogeneous results are found: While few examples of sophisticated methodology exist, the design of the majority of the studies is poor. A response to the situation described can be seen in Paul Martini's book "Methodology of Therapeutic Investigation", first published in 1932. Paul Martini's biography, his criticism of the situation of clinical-therapeutic investigation of his time, the major points of his methodology and the reception of the book in Germany and abroad are described.
A systematic review of interventions to improve recall of medical advice in healthcare consultations
Watson, Philip WB; McKinstry, Brian
2009-01-01
Abstract Background In order for patients to adhere to healthcare advice, it is essential that they are able to recall this following a consultation. Although psychological research exists which highlights techniques and factors postulated to influence recall, only a limited body of work has been conducted to evaluate their effectiveness in a clinical context. Aim To carry out a systematic review of intervention trials designed to enhance recall of medical information. Methods We searched Medline (1950–April 2007); Embase (1980–April 2007); Cinahl (1982–April 2007); PsychINFO (1969–2007); and the Cochrane Library Collection. Secondary searches were made through reference to relevant journals and reference lists from relevant papers/review papers. Results From 69 papers provisionally identified, 34 papers met the inclusion criteria. Nine recall interventions had been evaluated (audio recordings, written materials, adjunct questions, prompt sheets, visual aids, cognitive strategies, rehearsal, communication styles and personalized teaching). Despite the experimental and theoretical evidence which could have informed cognitive interventions to enhance recall of healthcare advice, most studies primarily focused on the use of written and/or audio-recorded medical instructions. Although the majority of studies supported these approaches insofar as they enhanced recall, the findings were equivocal. Conclusion While written and tape-recorded instructions appear to improve recall in most situations, a dearth of interventions incorporating psychological theory was readily apparent. Further research is required in clinical settings to determine if cognitive interventions based on a more over-arching psychological model of recall are effective. PMID:19531618

Background: For decades, the major source of information used to make therapeutic decisions by patients with diabetes has been glucose measurements using capillary blood samples. Knowledge gained from clinical studies, for example, on the impact of metabolic control on diabetes-related complications, is based on such measurements. Different to traditional blood glucose measurement systems, systems for continuous glucose monitoring (CGM) measure glucose in interstitial fluid (ISF). The assumption is that glucose levels in blood and ISF are practically the same and that the information provided can be used interchangeably. Thus, therapeutic decisions, that is, the selection of insulin doses, are based on CGM system results interpreted as though they were blood glucose values. Methods: We performed a more detailed analysis and interpretation of glucose profiles obtained with CGM in situations with high glucose dynamics to evaluate this potentially misleading assumption. Results: Considering physical activity, hypoglycemic episodes, and meal-related differences between glucose levels in blood and ISF uncover clinically relevant differences that can make it risky from a therapeutic point of view to use blood glucose for therapeutic decisions. Conclusions: Further systematic and structured evaluation as to whether the use of ISF glucose is more safe and efficient when it comes to acute therapeutic decisions is necessary. These data might also have a higher prognostic relevance when it comes to long-term metabolic consequences of diabetes. In the long run, it may be reasonable to abandon blood glucose measurements as the basis for diabetes management and switch to using ISF glucose as the appropriate therapeutic target. PMID:28322063
Affect regulation, brain development, and behavioral/emotional health in adolescence.
Dahl, R E
2001-01-01
This paper addresses the importance of affect regulation (AR) in relation to a broad range of behavioral and emotional health problems that emerge during adolescence. AR is defined as the adaptive modulation of emotional experience to serve a goal or purpose. This conceptualization of AR emphasizes the use of cognitive skills to guide, inhibit, or modify emotion and behavior, including the expression of emotional responses, in learned, strategic ways-skills that ultimately underpin adult levels of social maturity and the ability to show "responsible" behavior across a range of emotional situations. Neurobehavioral systems that subserve these AR skills include areas of the inferior and orbital prefrontal cortex (PFC), with rich interconnections to several limbic structures and other cortical areas, including the dorsolateral PFC. Adolescence represents an important developmental period in the functional maturation of adult AR skills; it is also a critical time in the development of clinical disorders of AR (eg, rates of depression increase dramatically and gender differences in depression emerge). Maturational changes in AR that occur during adolescence-particularly with respect to the role of emotions influencing responsible decision making-are also relevant to understanding key aspects of the developmental pathways of some behavioral health problems, such as alcohol use and nicotine dependence. A strong case is made for developmental research in affective neuroscience aimed at this important maturational period, particularly the kind of transdisciplinary research leading toward mechanistic understanding of the development of adolescent-onset disorders. Improving understanding in these areas could ultimately lead to the development of early interventions in targeted high-risk populations, and has enormous clinical and social policy relevance.

Bisphosphonates are potent inhibitors of osteoclast-mediated bone resorption. Recent interest has centered on the effects of bisphosphonates on osteoblasts. Chronic dosing of osteoblasts with solubilized bisphosphonates has been reported to enhance osteogenesis and mineralization in vitro. However, this methodology poorly reflects the in vivo situation, where free bisphosphonate becomes rapidly bound to mineralized bone surfaces. To establish a more clinically relevant cell culture model, we cultured bone cells on calcium phosphate coated quartz discs pre-treated with the potent nitrogen-containing bisphosphonate, zoledronic acid (ZA). Binding studies utilizing [{sup 14}C]-labeled ZA confirmed that the bisphosphonate bound in a concentration-dependent manner over themore » 1-50 {mu}M dose range. When grown on ZA-treated discs, the viability of bone-marrow derived osteoclasts was greatly reduced, while the viability and mineralization of the osteoblastic MC3T3-E1 cell line were largely unaffected. This suggests that only bone resorbing cells are affected by bound bisphosphonate. However, this system does not account for transient exposure to unbound bisphosphonate in the hours following a clinical dosing. To model this event, we transiently treated osteoblasts with ZA in the absence of a calcified surface. Osteoblasts proved highly resistant to all transitory treatment regimes, even when utilizing ZA concentrations that prevented mineralization and/or induced cell death when dosed chronically. This study represents a pharmacologically more relevant approach to modeling bisphosphonate treatment on cultured bone cells and implies that bisphosphonate therapies may not directly affect osteoblasts at bone surfaces.« less

Improving access can increase the providers a patient sees, and cause coordination challenges. For initiatives that increase care across health care settings, measuring patient experiences with access and care coordination will be crucial. Map existing survey measures of patient experiences with access and care coordination expected to be relevant to patients accessing care across settings. Preliminarily examine whether aspects of access and care coordination important to patients are represented by existing measures. Structured literature review of domains and existing survey measures related to access and care coordination across settings. Survey measures, and preliminary themes from semistructured interviews of 10 patients offered VA-purchased Community Care, were mapped to identified domains. We identified 31 existing survey instruments with 279 items representing 6 access and 5 care coordination domains relevant to cross-system care. Domains frequently assessed by existing measures included follow-up coordination, primary care access, cross-setting coordination, and continuity. Preliminary issues identified in interviews, but not commonly assessed by existing measures included: (1) acceptability of distance to care site given patient's clinical situation; (2) burden on patients to access and coordinate care and billing; (3) provider familiarity with Veteran culture and VA processes. Existing survey instruments assess many aspects of patient experiences with access and care coordination in cross-system care. Systems assessing cross-system care should consider whether patient surveys accurately reflect the level of patients' concerns with burden to access and coordinate care, and adequately reflect the impact of clinical severity and cultural familiarity on patient preferences.

Integrated relaxation pressure (IRP) is a key metric for diagnosing esophagogastric junction outflow obstruction (EGJOO). However, its normal value might be different according to the manufacturer of high-resolution manometry (HRM). This study aimed to investigate optimal value of IRP for diagnosing EGJOO in Sandhill HRM and to find clinicomanometric variables to segregate clinically relevant EGJOO. We analyzed 262 consecutive subjects who underwent HRM between June 2011 and December 2016 showing elevated median IRP (> 15 mm Hg) but did not satisfy criteria for achalasia. Clinically relevant subjects were defined as follows: (i) subsequent HRM met achalasia criteria during follow-up (early achalasia); (ii) Eckardt score was decreased at least two points without exceeding a score of 3 after pneumatic dilatation (variant achalasia); and (iii) significant passage disturbance on esophagogram without structural abnormality (possible achalasia). Seven subjects were clinically relevant, including two subjects with early achalasia, four subjects with variant achalasia, and one subject with possible achalasia. All clinically relevant subjects had IRP 20 mm Hg or above. Among subjects (n = 122) with IRP 20 mm Hg or more, clinically relevant group (n = 7) had significantly higher rate of dysphagia (100% vs 24.3%, P < .001) and compartmentalized pressurization (85.7% vs 21.7%, P = .001) compared to clinically non-relevant group (n = 115). Our results suggest that IRP of 20 mm Hg or higher could segregate clinically relevant subjects showing EGJOO in Sandhill HRM. Additionally, if subjects have both dysphagia and compartmentalized pressurization, careful follow-up is essential. © 2017 John Wiley & Sons Ltd.

Cartographic visualizations of crises are used to create a Common Operational Picture (COP) and enforce Situational Awareness by presenting and representing relevant information. As nearly all crises affect geospatial entities, geo-data representations have to support location-specific decision-making throughout the crises. Since, Operator's attention span and their working memory are limiting factors for the process of getting and interpreting information; the cartographic presentation has to support individuals in coordinating their activities and with handling highly dynamic situations. The Situational Awareness of operators in conjunction with a COP are key aspects of the decision making process and essential for coming to appropriate decisions. Utility networks are one of the most complex and most needed systems within a city. The visualization of utility infrastructure in crisis situations is addressed in this paper. The paper will provide a conceptual approach on how to simplify, aggregate, and visualize multiple utility networks and their components to meet the requirements of the decision-making process and to support Situational Awareness.

Arboviruses are an emerging group of viruses that are causing increasing health concerns globally, including in Europe. Clinical presentation usually consists of a nonspecific febrile illness that may be accompanied by rash, arthralgia and arthritis, with or without neurological or haemorrhagic syndromes. The range of differential diagnoses of other infectious and noninfectious aetiologies is broad, presenting a challenge for physicians. While knowledge of the geographical distribution of pathogens and the current epidemiological situation, incubation periods, exposure risk factors and vaccination history can help guide the diagnostic approach, the nonspecific and variable clinical presentation can delay final diagnosis. This narrative review aims to summarize the main clinical and laboratory-based findings of the three most common imported arboviruses in Europe. Evidence is extracted from published literature and clinical expertise of European arbovirus experts. We present three cases that highlight similarities and differences between some of the most common travel-related arboviruses imported to Europe. These include a patient with chikungunya virus infection presenting in Greece, a case of dengue fever in Turkey and a travel-related case of Zika virus infection in Romania. Early diagnosis of travel-imported cases is important to reduce the risk of localized outbreaks of tropical arboviruses such as dengue and chikungunya and the risk of local transmission from body fluids or vertical transmission. Given the global relevance of arboviruses and the continuous risk of (re)emerging arbovirus events, clinicians should be aware of the clinical syndromes of arbovirus fevers and the potential pitfalls in diagnosis.

Determination of minimal clinically important change in early and advanced Parkinson's disease.
Hauser, Robert A; Auinger, Peggy
2011-04-01
Two common primary efficacy outcome measures in Parkinson's disease (PD) are change in Unified Parkinson's Disease Rating Scale (UPDRS) scores in early PD and change in "off" time in patients with motor fluctuations. Defining the minimal clinically important change (MCIC) in these outcome measures is important to interpret the clinical relevance of changes observed in clinical trials and other situations. We analyzed data from 2 multicenter, placebo-controlled, randomized clinical trials of rasagiline; TEMPO studied 404 early PD subjects, and PRESTO studied 472 levodopa-treated subjects with motor fluctuations. An anchor-based approach using clinical global impression of improvement (CGI-I) was used to determine MCIC for UPDRS scores and daily "off" time. MCIC was defined as mean change in actively treated subjects rated minimally improved on CGI-I. Receiver operating characteristic (ROC) curves defined optimal cutoffs discriminating between changed and unchanged subjects. MCIC for improvement in total UPDRS score (parts I-III) in early PD was determined to be -3.5 points based on mean scores and -3.0 points based on ROC curves. In addition, we found an MCIC for reduction in "off" time of 1.0 hours as defined by mean reduction in "off" time in active treated subjects self-rated as minimally improved on CGI-I minus mean reduction in "off" time in placebo-treated subjects self-rated as unchanged (1.9-0.9 hours). We hypothesize that many methodological factors can influence determination of the MCIC, and a range of values is likely to emerge from multiple studies. Copyright © 2011 Movement Disorder Society.
Peer influence on students' estimates of performance: social comparison in clinical rotations.
Raat, A N Janet; Kuks, Jan B M; van Hell, E Ally; Cohen-Schotanus, Janke
2013-02-01
During clinical rotations, students move from one clinical situation to another. Questions exist about students' strategies for coping with these transitions. These strategies may include a process of social comparison because in this context it offers the student an opportunity to estimate his or her abilities to master a novel rotation. These estimates are relevant for learning and performance because they are related to self-efficacy. We investigated whether student estimates of their own future performance are influenced by the performance level and gender of the peer with whom the student compares him- or herself. We designed an experimental study in which participating students (n = 321) were divided into groups assigned to 12 different conditions. Each condition entailed a written comparison situation in which a peer student had completed the rotation the participant was required to undertake next. Differences between conditions were determined by the performance level (worse, similar or better) and gender of the comparison peer. The overall grade achieved by the comparison peer remained the same in all conditions. We asked participants to estimate their own future performance in that novel rotation. Differences between their estimates were analysed using analysis of variance (ANOVA). Students' estimates of their future performance were highest when the comparison peer was presented as performing less well and lowest when the comparison peer was presented as performing better (p < 0.001). Estimates of male and female students in same-gender comparison conditions did not differ. In two of three opposite-gender conditions, male students' estimates were higher than those of females (p < 0.001 and p < 0.05, respectively). Social comparison influences students' estimates of their future performance in a novel rotation. The effect depends on the performance level and gender of the comparison peer. This indicates that comparisons against particular peers may strengthen or diminish a student's self-efficacy, which, in turn, may ease or hamper the student's learning during clinical rotations. The study is limited by its experimental design. Future research should focus on students' comparison behaviour in real transitions. © Blackwell Publishing Ltd 2013.

The questionnaire was adopted so as to investigate the attitudes and recognition of the manufacture eneprises of TCM diagnosis, treatment and rehabilitation equipment (DTRE) to the technical standards of, relevant products. It was found that the construction of the industrial standard and the national standard was lagged behind on TCM DTRE. Under the new situation, the enterprises are highly willing to participate in the development of the industrial, national and international standards and have a certain of understanding on the standard development. Nearly 80 % of enterprises believed that it was necessary to set up the relevant mirror organization for the development of industrial, national and international standard of TCM DITRE. In the future, the standard construction of TCM DTRE must face to the new situation. The constant increasing of the enterprises. and scientific research organizations in the standard construction must promote the development of TCM DTRE.
Sensor-based activity recognition using extended belief rule-based inference methodology.

The recently developed extended belief rule-based inference methodology (RIMER+) recognizes the need of modeling different types of information and uncertainty that usually coexist in real environments. A home setting with sensors located in different rooms and on different appliances can be considered as a particularly relevant example of such an environment, which brings a range of challenges for sensor-based activity recognition. Although RIMER+ has been designed as a generic decision model that could be applied in a wide range of situations, this paper discusses how this methodology can be adapted to recognize human activities using binary sensors within smart environments. The evaluation of RIMER+ against other state-of-the-art classifiers in terms of accuracy, efficiency and applicability was found to be significantly relevant, specially in situations of input data incompleteness, and it demonstrates the potential of this methodology and underpins the basis to develop further research on the topic.
Muscarine- and carbachol-induced aggressions: fear and irritable kinds of aggressions.
Beleslin, D B; Samardzić, R
1977-12-28
In unaneasthetized and unrestrained cats, muscarine and carbachol were injected into the cerebral ventricles. The kind of aggressive behaviour depended on the cholinomimetic drug and was classified as fear and an irritable kind of aggression. Muscarine induced the fear kind of aggression. The aggressive behaviour was usually preceded by attempts to escape and the attack was relevant to the situation. For the attack the presence of some threatening agent was needed. The aggression was accompanied by intense motor but less autonomic activation. On the other hand, carbachol induced an irritable kind of aggression and had the following characteristics: for the attack the presence of some threatening agent was not needed; the attack was not relevant to the situation; the aggression was not preceded by attempts to escape; and the aggressive behaviour was accompanied by intense motor and autonomic activation. It is concluded that cholinoceptive mechanisms are involved in the control of aggressive behaviour.

Our goals in this reflection are to (i) identify the ethical dimensions inherent in any clinical encounter and (ii) bring to the forefront of our pediatric neurology practice the myriad of opportunities to explore and learn from these ethical questions. We highlight specifically Beauchamp and Childress's principles of biomedical ethics. We use the terms ethics in common clinical practice and an ethical lens to remind people of the ubiquity of ethical situations and the usefulness of using existing ethical principles to analyze and resolve difficult situations in clinical practice. We start with a few common situations with which many of us tend to struggle. We describe what we understand as ethics and how and why developments in technology, novel potential interventions, policies, and societal perspectives challenge us to think about and debate ethical issues. Individual patients are not a singular population; each patient has their own unique life situations, culture, goals, and expectations that need to be considered with a good dose of humanity and humility. We believe that using an ethical lens-by which we mean making an explicit effort to identify and consider these issues openly-will help us to achieve this goal in practice, education, and research.
Public health situation awareness: toward a semantic approach

We propose a knowledge-based public health situation awareness system. The basis for this system is an explicit representation of public health situation awareness concepts and their interrelationships. This representation is based upon the users" (public health decision makers) cognitive model of the world, and optimized towards the efficacy of performance and relevance to the public health situation awareness processes and tasks. In our approach, explicit domain knowledge is the foundation for interpretation of public health data, as apposed to conventional systems where the statistical methods are the essence of the processes. Objectives: To develop a prototype knowledge-based system for public health situation awareness and to demonstrate the utility of knowledge intensive approaches in integration of heterogeneous information, eliminating the effects of incomplete and poor quality surveillance data, uncertainty in syndrome and aberration detection and visualization of complex information structures in public health surveillance settings, particularly in the context of bioterrorism (BT) preparedness. The system employs the Resource Definition Framework (RDF) and additional layers of more expressive languages to explicate the knowledge of domain experts into machine interpretable and computable problem-solving modules that can then guide users and computer systems in sifting through the most "relevant" data for syndrome and outbreak detection and investigation of root cause of the event. The Center for Biosecurity and Public Health Informatics Research is developing a prototype knowledge-based system around influenza, which has complex natural disease patterns, many public health implications, and is a potential agent for bioterrorism. The preliminary data from this effort may demonstrate superior performance in information integration, syndrome and aberration detection, information access through information visualization, and cross-domain investigation of the root causes of public health events.

Anxiety disorders are among the most common mental health problems in youth, and faulty interpretation bias has been positively linked to anxiety severity, even within anxiety-disordered youth. Quick, reliable assessment of interpretation bias may be useful in identifying youth with certain types of anxiety or assessing changes on cognitive bias during intervention. This study examined the factor structure, reliability, and validity of the Self-report of Ambiguous Social Situations for Youth (SASSY) scale, a self-report measure developed to assess interpretation bias in youth. Participants (N=488, age 7 to 17) met diagnostic criteria for Social Phobia, Generalized Anxiety Disorder, and/or Separation Anxiety Disorder. An exploratory factor analysis was performed on baseline data from youth participating in a large randomized clinical trial. Exploratory factor analysis yielded two factors (Accusation/Blame, Social Rejection). The SASSY full scale and Social Rejection factor demonstrated adequate internal consistency, convergent validity with social anxiety, and discriminant validity as evidenced by non-significant correlations with measures of non-social anxiety. Further, the SASSY Social Rejection factor accurately distinguished children and adolescents with Social Phobia from those with other anxiety disorders, supporting its criterion validity, and revealed sensitivity to changes with treatment. Given the relevance to youth with social phobia, pre- and post-intervention data were examined for youth social phobia to test sensitivity to treatment effects; results suggested that SASSY scores reduced for treatment responders. Findings suggest the potential utility of the SASSY Social Rejection factor as a quick, reliable, and efficient way of assessing interpretation bias in anxious youth, particularly as related to social concerns, in research and clinical settings.
[Viral hepatitis in travellers].
Abreu, Cândida
2007-01-01
Considering the geographical asymmetric distribution of viral hepatitis A, B and E, having a much higher prevalence in the less developed world, travellers from developed countries are exposed to a considerable and often underestimated risk of hepatitis infection. In fact a significant percentage of viral hepatitis occurring in developed countries is travel related. This results from globalization and increased mobility from tourism, international work, humanitarian and religious missions or other travel related activities. Several studies published in Europe and North America shown that more than 50% of reported cases of hepatitis A are travel related. On the other hand frequent outbreaks of hepatitis A and E in specific geographic areas raise the risk of infection in these restricted zones and that should be clearly identified. Selected aspects related with the distribution of hepatitis A, B and E are reviewed, particularly the situation in Portugal according to the published studies, as well as relevant clinical manifestations and differential diagnosis of viral hepatitis. Basic prevention rules considering enteric transmitted hepatitis (hepatitis A and hepatitis E) and parenteral transmitted (hepatitis B) are reviewed as well as hepatitis A and B immunoprophylaxis. Common clinical situations and daily practice "pre travel" advice issues are discussed according to WHO/CDC recommendations and the Portuguese National Vaccination Program. Implications from near future availability of a hepatitis E vaccine, a currently in phase 2 trial, are highlighted. Potential indications for travellers to endemic countries like India, Nepal and some regions of China, where up to 30% of sporadic cases of acute viral hepatitis are caused by hepatitis E virus, are considered. Continued epidemiological surveillance for viral hepatitis is essential to recognize and control possible outbreaks, but also to identify new viral hepatitis agents that may emerge as important global health issues.

To classify events of actual or potential harm to primary care patients using a multilevel taxonomy of cognitive and system factors. Observational study of patient safety events obtained via a confidential but not anonymous reporting system. Reports were followed up with interviews where necessary. Events were analysed for their causes and contributing factors using causal trees and were classified using the taxonomy. Five general medical practices in the West Midlands were selected to represent a range of sizes and types of patient population. All practice staff were invited to report patient safety events. Main outcome measures were frequencies of clinical types of events reported, cognitive types of error, types of detection and contributing factors; and relationship between types of error, practice size, patient consequences and detection. 78 reports were relevant to patient safety and analysable. They included 21 (27%) adverse events and 50 (64%) near misses. 16.7% (13/71) had serious patient consequences, including one death. 75.7% (59/78) had the potential for serious patient harm. Most reports referred to administrative errors (25.6%, 20/78). 60% (47/78) of the reports contained sufficient information to characterise cognition: "situation assessment and response selection" was involved in 45% (21/47) of these reports and was often linked to serious potential consequences. The most frequent contributing factor was work organisation, identified in 71 events. This included excessive task demands (47%, 37/71) and fragmentation (28%, 22/71). Even though most reported events were near misses, events with serious patient consequences were also reported. Failures in situation assessment and response selection, a cognitive activity that occurs in both clinical and administrative tasks, was related to serious potential harm.

Appropriate deliberate clinical inertia refers to the art of doing nothing as a positive clinical response. It includes shared decision-making to improve patient care with the use of clinical judgement. We discuss common clinical scenarios where the use of deliberate clinical inertia can occur. The insertion of peripheral intravenous cannulae, investigating patients with suspected renal colic and the investigation of low risk chest pain are all opportunities for the thoughtful clinician to 'stand there' and use effective patient communication to avoid low value tests and procedures. Awareness is key to identifying these opportunities to practice deliberate clinical inertia, as many of the situations may be so much a part of our environment that they are hidden in plain view. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Background The recovery of patients after an acute episode of illness or injury depends both on adequate medical treatment and on the early identification of needs for rehabilitation care. The process of early beginning rehabilitation requires efficient communication both between health professionals and the patient in order to effectively address all rehabilitation goals. The currently used nursing taxonomies, however, are not intended for interdisciplinary use and thus may not contribute to efficient rehabilitation management and an optimal patient outcome. The ICF might be the missing link in this communication process. The objective of this study was to identify the categories of the International Classification of Functioning, Disability and Health (ICF) categories relevant for nursing care in the situation of acute and early post-acute rehabilitation. Methods First, in a consensus process, "Leistungserfassung in der Pflege" (LEP) nursing interventions relevant for the situation of acute and early post-acute rehabilitation were selected. Second, in an integrated two-step linking process, two nursing experts derived goals of LEP nursing interventions from their practical knowledge and selected corresponding ICF categories most relevant for patients in acute and post-acute rehabilitation (ICF Core Sets). Results Eighty-seven percent of ICF Core Set categories could be linked to goals of at least one nursing intervention variable of LEP. The ICF categories most frequently linked with LEP nursing interventions were respiration functions, experience of self and time functions and focusing attention. Thirteen percent of ICF Core Set categories could not be linked with LEP nursing interventions. The LEP nursing interventions which were linked with the highest number of different ICF-categories of all were "therapeutic intervention", "patient-nurse communication/information giving" and "mobilising". Conclusion The ICF Core Sets for the acute hospital and early post-acute rehabilitation facilities are highly relevant for rehabilitation nursing. Linking nursing interventions with ICF Core Set categories is a feasible way to analyse nursing. Using the ICF Core Sets to describe goals of nursing interventions both facilitates inter-professional communication and respects patient's needs. The ICF may thus be a useful framework to set nursing intervention goals. PMID:18282288

Background Aggressive situations occurring within mental health services can harm service users, staff, and the therapeutic environment. There is a consensus that the aggression phenomenon is multidimensional, but the picture is still unclear concerning the complex interplay of causal variables and their respective impact. To date, only a small number of empirical studies include users’ views of relevant factors. The main objective of this review is to identify and synthesize evidence relating to service users’ experiences and views of aggressive situations in mental health settings. Methods We included qualitative studies of any design reporting on service users’ own experiences of conditions contributing to aggressive situations in mental health care and their views on preventative strategies. Eligible articles were identified through an electronic database search (PsycINFO, PubMed, Ovid Nursing Database, Embase, and CINAHL), hand search, and cross-referencing. Extracted data were combined and interpreted using aspects of thematic synthesis. Results We reviewed 5,566 records and included 13 studies (ten qualitative and three mixed methods). Service users recognized that both their own mental state and negative aspects of the treatment environment affected the development of aggressive situations. Themes were derived from experiential knowledge and included calls to be involved in questions regarding how to define aggression and relevant triggers, and how to prevent aggressive encounters effectively. The findings suggest that incidents are triggered when users experience staff behavior as custodial rather than caring and when they feel ignored. Conclusion The findings highlight the importance of staffs’ knowledge and skills in communication for developing relationships based on sensitivity, respect, and collaboration with service users in order to prevent aggressive situations. An important factor is a treatment environment with opportunities for meaningful activities and a preponderance of trained staff who work continuously on the development of conditions and skills for collaborative interaction with users.

Aggressive situations occurring within mental health services can harm service users, staff, and the therapeutic environment. There is a consensus that the aggression phenomenon is multidimensional, but the picture is still unclear concerning the complex interplay of causal variables and their respective impact. To date, only a small number of empirical studies include users' views of relevant factors. The main objective of this review is to identify and synthesize evidence relating to service users' experiences and views of aggressive situations in mental health settings. We included qualitative studies of any design reporting on service users' own experiences of conditions contributing to aggressive situations in mental health care and their views on preventative strategies.

Physical therapists improve the functional ability of patients after injury and disease. A unique component of their practice is the ability to use the movement of their own bodies to effect change in their patients. This ability has been recognized as a distinctive attribute of expert physical therapists. The purpose of this qualitative situational analysis study was to examine how physical therapist clinical instructors perceive and facilitate their students' emerging integration of movement in practice. Data collection and analysis were guided by a theoretical framework for understanding "professional ways of being." Data were analyzed using coding and mapping strategies consistent with situational analysis techniques. The study included 5 physical therapist clinical instructors and their respective 5 physical therapist students. Data were collected during beginning, midterm, and final weeks of the students' clinical internships using participant interviews, observation, and document analysis. Coded data were summarized using situational analysis mapping strategies, resulting in 11 maps. These maps were further analyzed and reduced to 5 thematic behaviors enacted by a clinical instructor as he or she helps facilitate students' use of movement in practice. These behaviors are adapt, prepare, enhance, connect , and develop . The limited number of participants and the relative homogeneity of the student sample may have limited the diversity of data collected. The 5 behaviors are useful when considered as a trajectory of development. To our knowledge, this study marks the first description of how physical therapist clinical instructors develop students' use of movement in practice and how to enact behaviors important in students' continued professional development. The findings are important for clinical instructors and academic programs considering how best to prepare students to use movement and develop their skills early in practice. © 2017 American Physical Therapy Association
Learning Situations in Nursing Education: A Concept Analysis.
Shahsavari, Hooman; Zare, Zahra; Parsa-Yekta, Zohreh; Griffiths, Pauline; Vaismoradi, Mojtaba

The nursing student requires opportunities to learn within authentic contexts so as to enable safe and competent practice. One strategy to facilitate such learning is the creation of learning situations. A lack of studies on the learning situation in nursing and other health care fields has resulted in insufficient knowledge of the characteristics of the learning situation, its antecedents, and consequences. Nurse educators need to have comprehensive and practical knowledge of the definition and characteristics of the learning situation so as to enable their students to achieve enhanced learning outcomes. The aim of this study was to clarify the concept of the learning situation as it relates to the education of nurses and improve understanding of its characteristics, antecedents, and consequences. The Bonis method of concept analysis, as derived from the Rodgers' evolutionary method, provided the framework for analysis. Data collection and analysis were undertaken in two phases: "interdisciplinary" and "intra-disciplinary." The data source was a search of the literature, encompassing nursing and allied health care professions, published from 1975 to 2016. No agreement on the conceptual phenomenon was discovered in the international literature. The concept of a learning situation was used generally in two ways and thus classified into the themes of: "formal/informal learning situation" and "biologic/nonbiologic learning situation." Antecedents to the creation of a learning situation included personal and environmental factors. The characteristics of a learning situation were described in terms of being complex, dynamic, and offering potential and effective learning opportunities. Consequences of the learning situation included enhancement of the students' learning, professionalization, and socialization into the professional role. The nurse educator, when considering the application of the concept of a learning situation in their educational planning, must acknowledge that the application of this concept will include the student's clinical learning experiences. More studies are required to determine factors influencing the creation of a successful learning situation from the perspectives of nurse educators and nursing students, clinical nurses and patients.
Meaning of living with severe chronic obstructive lung disease: a qualitative study.

To explore what it means for patients to live with chronic obstructive pulmonary disease (COPD) as an incurable and constantly progressing disease. Qualitative longitudinal study using narrative and semistructured interviews. This paper presents findings of the initial interviews. Analysis using grounded theory. Lung care clinics and community care in Lower Saxony, Germany. 17 patients with advanced-stage COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) III/IV). Analysis shows that these patients have difficulties accepting their life situation and feel at the mercy of the disease, which could be identified as a core-experienced phenomenon. Over a long period of time, patients have only a vague feeling of being ill, caused by uncertain knowledge, slow progress and doubtful attribution of clinical symptoms of the disease (causal conditions). As an action strategy, patients try to maintain daily routines for as long as possible after diagnosis. Both effective standard and rescue medication, which helps to reduce breathlessness and other symptoms, and the feeling of being faced with one's own responsibility (intervening conditions) support this strategy, whereby patients' own responsibility is too painful to acknowledge. As a consequence, patients try to deny the threat to life for a long period of time. Frequently, they need to experience facing their own limits, often in the form of an acute crisis, to realise their health situation. The experience of the illness is contextualised by a continuous increase in limited mobility and social isolation. In order to help patients to improve disease awareness, to accept their life situation and to improve their reduced quality of life, patients may benefit from the early integration of palliative care (PC), considering its multiprofessional patient-centred and team-centred approach. Psychological support and volunteer work, which are relevant aspects of PC, should be appropriate to address psychosocial needs. More research is needed to evaluate how patients could benefit from early PC. Published by the BMJ Publishing Group Limited.

To explore the current situation, existing problems and possible causes of said problems with regards to physician-nurse communication under an environment of increasingly widespread usage of Hospital Information Systems and to seek out new potential strategies in information technology to improve physician-nurse communication. Semi-structured interviews were conducted with 20 physicians and nurses in five leading tertiary grade A hospitals in Beijing, China (two physicians and two nurses in each hospital). The interviews primarily included three aspects comprising the current situation and problems of clinical physician-nurse communication, the application and problems of Hospital Information Systems, and assessments on the improvement of physician-nurse communication through the usage of information technology. The inductive conventional content analysis approach was employed. (1) Physicians and nurses are generally quite satisfied with the current situation of communication. However, the information needs of nurses are prone to being overlooked, and the communication methods are primarily synchronous communication such as face-to-face and phone communication. (2) Hospital Information Systems are gradually being used for physician-nurse communication; in the meantime, physicians and nurses face challenges with regards to the improvement of physician-nurse communication through the usage of information technology. Challenges differ based on the different stages of using the system and the different levels of understanding of physicians and nurses towards information technology. Their dissatisfaction mainly deals with system errors and the level of convenience in using the system. (3) In-depth interviews found that in general, physicians and nurses have a strong interest and trust in improving physician-nurse communication through appropriate information technology, e.g., communication methods such as information reminders for physicians and nurses through mobile devices and instant voice-to-text conversion methods. There are objective risks in physician-nurse communication in Chinese hospitals, and clinical information systems lack solutions to the relevant problems. Developing a dedicated, mobile, quick and convenient module for physician-nurse communication within existing hospital information system with automatic reminders for important information that segregates between synchronous and asynchronous communication according to the different types of information could help improve physician-nurse communication.
Trustworthiness and relevance in web-based clinical question answering.
Cruchet, Sarah; Boyer, Célia; van der Plas, Lonneke
2012-01-01
Question answering systems try to give precise answers to a user's question posed in natural language. It is of utmost importance that the answers returned are relevant to the user's question. For clinical QA, the trustworthiness of answers is another important issue. Limiting the document collection to certified websites helps to improve the trustworthiness of answers. On the other hand, limited document collections are known to harm the relevancy of answers. We show, however, in a comparative evaluation, that promoting trustworthiness has no negative effect on the relevance of the retrieved answers in our clinical QA system. On the contrary, the answers found are in general more relevant.
Processing and memory of information presented in narrative or expository texts.
Wolfe, Michael B W; Woodwyk, Joshua M
2010-09-01
Previous research suggests that narrative and expository texts differ in the extent to which they prompt students to integrate to-be-learned content with relevant prior knowledge during comprehension. We expand on previous research by examining on-line processing and representation in memory of to-be-learned content that is embedded in narrative or expository texts. We are particularly interested in how differences in the use of relevant prior knowledge leads to differences in terms of levels of discourse representation (textbase vs. situation model). A total of 61 university undergraduates in Expt 1, and 160 in Expt 2. In Expt 1, subjects thought out loud while comprehending circulatory system content embedded in a narrative or expository text, followed by free recall of text content. In Expt 2, subjects read silently and completed a sentence recognition task to assess memory. In Expt 1, subjects made more associations to prior knowledge while reading the expository text, and recalled more content. Content recall was also correlated with amount of relevant prior knowledge for subjects who read the expository text but not the narrative text. In Expt 2, subjects reading the expository text (compared to the narrative text) had a weaker textbase representation of the to-be-learned content, but a marginally stronger situation model. Results suggest that in terms of to-be-learned content, expository texts trigger students to utilize relevant prior knowledge more than narrative texts.

To understand how collaborators reconcile the often conflicting needs of awareness and privacy, we studied a large software development project in a multinational corporation involving individuals at sites in the U.S. and India. We present a theoretical framework describing privacy management practices and their determinants that emerged from field visits, interviews, and questionnaire responses. The framework identifies five relevant situational characteristics: issue(s) under consideration, physical place(s) involved in interaction(s), temporal aspects, affordances and limitations presented by technology, and nature of relationships among parties. Each actor, in turn, interprets the situation based on several simultaneous influences: self, team, work site, organization, and cultural environment. This interpretation guides privacy management action(s). Past actions form a feedback loop refining and/or reinforcing the interpretive influences. The framework suggests that effective support for privacy management will require that designers follow a socio-technical approach incorporating a wider scope of situational and interpretive differences.

In environmental remediation after nuclear accidents, radioactive wastes have to be appropriately managed in existing exposure situations with contamination resulting from the emission of radionuclides by such accidents. In this paper, a framework of radiation protection from radioactive waste management in existing exposure situations for application to the practical and reasonable waste management in contaminated areas, referring to related ICRP recommendations was proposed. In the proposed concept, intermediate reference levels for waste management are adopted gradually according to the progress of the reduction in the existing ambient dose in the environment on the basis of the principles of justification and optimisation by taking into account the practicability of the management of radioactive waste and environmental remediation. It is essential to include the participation of relevant stakeholders living in existing exposure situations in the selection of reference levels for the existing ambient dose and waste management.

Heat transfer from nanoparticles: a corresponding state analysis.
Merabia, Samy; Shenogin, Sergei; Joly, Laurent; Keblinski, Pawel; Barrat, Jean-Louis
2009-09-08
In this contribution, we study situations in which nanoparticles in a fluid are strongly heated, generating high heat fluxes. This situation is relevant to experiments in which a fluid is locally heated by using selective absorption of radiation by solid particles. We first study this situation for different types of molecular interactions, using models for gold particles suspended in octane and in water. As already reported in experiments, very high heat fluxes and temperature elevations (leading eventually to particle destruction) can be observed in such situations. We show that a very simple modeling based on Lennard-Jones (LJ) interactions captures the essential features of such experiments and that the results for various liquids can be mapped onto the LJ case, provided a physically justified (corresponding state) choice of parameters is made. Physically, the possibility of sustaining very high heat fluxes is related to the strong curvature of the interface that inhibits the formation of an insulating vapor film.

People with disability (PWD) in Indonesia are often neglected by society. Improving their life situation towards full participation in society is crucial. As a health strategy, rehabilitation can improve func-tioning, quality of life and participation in society. However, rehabilitation services in Indonesia need improvement. Making a situation analysis of rehabilitation services and their provision in the country is a pre-requisite to taking any action towards improvement. This paper compiles available data related to disability and rehabilitation services in Indonesia, using the Rehabilitation Services Assessment Tool (RSAT) as a framework. Gaps in provision were analysed, resulting in the compilation of a list of generic recommendations to improve rehabilitation services in the country. Indonesia faces many challenges in rehabilitation services, including the health workforce and the provision of services. This situation analysis and list of generic recommendations may be used in further discussions with relevant stakeholders in the country to develop a national strategy to strengthen rehabilitation services.
Face-to-face: Perceived personal relevance amplifies face processing
Pittig, Andre; Schupp, Harald T.; Alpers, Georg W.

Abstract The human face conveys emotional and social information, but it is not well understood how these two aspects influence face perception. In order to model a group situation, two faces displaying happy, neutral or angry expressions were presented. Importantly, faces were either facing the observer, or they were presented in profile view directed towards, or looking away from each other. In Experiment 1 (n = 64), face pairs were rated regarding perceived relevance, wish-to-interact, and displayed interactivity, as well as valence and arousal. All variables revealed main effects of facial expression (emotional > neutral), face orientation (facing observer > towards > away) and interactions showed that evaluation of emotional faces strongly varies with their orientation. Experiment 2 (n = 33) examined the temporal dynamics of perceptual-attentional processing of these face constellations with event-related potentials. Processing of emotional and neutral faces differed significantly in N170 amplitudes, early posterior negativity (EPN), and sustained positive potentials. Importantly, selective emotional face processing varied as a function of face orientation, indicating early emotion-specific (N170, EPN) and late threat-specific effects (LPP, sustained positivity). Taken together, perceived personal relevance to the observer—conveyed by facial expression and face direction—amplifies emotional face processing within triadic group situations. PMID:28158672
Self-efficacy in weight management.

Self-efficacy is an important mediating mechanism in advancing understanding of the treatment of obesity. This study developed and validated the Weight Efficacy Life-Style Questionnaire (WEL), improving on previous studies by the use of clinical populations, cross-validation of the initial factor analysis, exploration of the best fitting theoretical model of self-efficacy, and examination of change in treatment. The resulting 20-item WEL consists of five situational factors: Negative Emotions, Availability, Social Pressure, Physical Discomfort, and Positive Activities. A hierarchical model was found to provide the best fit to the data. Results from two separate clinical treatment studies (total N = 382) show that the WEL is sensitive to changes in global scores as well as to a subset of the five situational factor scores. Treatment programs may be incomplete if they change only a subset of the situational dimensions of self-efficacy. Theoretical and clinical implications are discussed.

The usage and dosage of Chinese patent medicine are determined by rigorous evaluation which include four clinical trail stages: I, II, III. But the usage and dosage of Chinese patent medicine are lacked re-evaluation after marketing. And this lead to unchanging or fixed of the usage and dosage of Chinese patent medicine instead of different quantity based on different situations in individual patients. The situation of Chinese patent medicine used in clinical application is far away from the idea of the "Treatment based on syndrome differentiation" in traditional Chinese medicine and personalized therapy. Human population pharmacokinetics provides data support to the personalized therapy in clinical application, and achieved the postmarking reevaluating of the usage and dosage of Chinese patent medicine. This paper briefly introduced the present situation, significance and the application of human population pharmacokinetics about re-evaluation of the usage and dosage of Chinese patent medicine after marketing.

Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.v. antibiotic administration is required to avoid fatal outcome. Early diagnosis is often delayed due to underestimation or confusion with cellulitis. We now compared the initial clinical and laboratory presentation of NF and cellulitis in detail to assess if a typical pattern can be identified that aids timely diagnosis of NF and avoidance of fatal outcome. 138 different clinical and laboratory features of 29 NF patients were compared to those of 59 age- and gender matched patients with severe erysipelas requiring a subsequent hospitalization time of ≥10 days. Differences in clinical presentation were not obvious; however, NF patients suffered significantly more often from strong pain. NF patients exhibited dramatically elevated CRP levels (5-fold, p>0.001). The overall laboratory risk indicator for necrotizing fasciitis (LRINEC) score was significantly higher in NF patients as compared to cellulitis. However, a modification of the score (alteration of laboratory parameters, addition of clinical parameters) led to a clear improvement of the score with a higher positive predictive value without losing specificity. In summary, clinical differentiation of NF from cellulitis appears to be hard. ‘Pain out of proportion’ may be an early sign for NF. An improvement of the LRINEC score emphasizing only relevant laboratory and clinical findings as suggested may aid the early diagnosis of NF in the future leading to improvement of disease outcome by enabling rapid adequate therapy.

The article explores how young people understand the risks of alcohol use and how these understandings are associated with differing drinking situations and social settings. By taking account of situational factors, the aim is to demonstrate how young people have highly nuanced notions of drinking styles that suit different drinking situations and of associated risks. The data for the research were gathered in 18 group interviews with Finnish ninth graders aged 14-15 years. Short film clips portraying young people in different drinking situations were used as stimulus material for the interviews. Data analysis focussed on the risk factors related to the social situations illustrated in the film clips. The results show that young people's risk assessments are not based on alcohol itself, but the magnitude of risk is estimated in relation to the social setting of the drinking situation. What is relevant for young people is whether the social situation allows them to make choices with which they feel comfortable. At the opposite pole of problem drinking was social drinking for the purpose of having fun together with other people in such a way that one remains in control of the drinking situation. From a prevention point of view, a key implication is that awareness of the risks is closely associated with situational and social factors. However, the awareness of those risks does not necessarily prevent young people from drinking because they may be accepted as part of the drinking experience. © The Author(s) 2014.
[Psychotherapy of chronic depression: contributions of CBASP by McCullough].
Kramer, U; Belz, M; Caspar, F
2013-04-01
Chronic depression is a frequent disorder and is usually treated using traditional approaches. These approaches rarely take into account the psychopathological specificities of the chronic evolution of the disorder. The present article aims at presenting the specific psychopathological nature of chronic depression and puts forward a treatment model that is particularly adapted to these specificities. The treatment model, Cognitive Behavioral Analysis System of Psychotherapy (CBASP; according to McCullough) is based on two theoretical models: the developmental theory by J. Piaget and the interpersonal model by D. Kiesler. According to McCullough, the cognitive affective functioning of chronically depressed patients is comparable with the one of a child who has not reached the Piagetian stage of logical operations. Their thinking is global, pre-logical and presents with monologues, instead of internal dialogues. These patients are incapable of effective controlling and regulating of emotions and of constructive accommodation of established schemas, when confronted with novel experiences. Finally, these patients are unaware of their interpersonal effects on the environment they unwillingly have. The latter are conceptualized using Kiesler's conceptualization of psychopathology. According to this model, the patient sends implicit relational "messages" provoking interpersonal "pulls" in the interaction partner (e.g., the therapist). These pulls are assessed and may be graphically represented using a Circumplex Model, also called the Kiesler-circle, and is the basis of the case conceptualization in the psychotherapy with chronically depressed patients. CBASP has developed based on the clinical implications of these models and combines them in an original fashion. Two lines of intervention result from the models: (1) situational analysis, which analyzes the links between behavior in a particular situation and the person's goal or desire related to the particular situation, and (2) interpersonal techniques based on the notions of transference and counter-transference. On one hand, situational analysis follows several steps linking the patient's behavior with his/her desired outcome, which is compared to the real outcome in the situation. The patient's interpretations are amended in a second step, using the desired outcome as an anchor. On the other hand, interpersonal techniques imply the therapist's stance of disciplined personal involvement, meaning a controlled way of therapist self-disclosure facing the patient, with the aim of experiencing by the patient, that his/her behavior does not remain without specific, immediate and authentic consequences in the environment. This experience by the patient should allow him/her to (re-)establish the perceived functionality of the patient's behavior in interpersonal encounters. We underline the relevance of the approach by citing several empirical studies which have established the efficacy of the model, in specific clinical conditions that are the combined treatment with anti-depressant medication, a sufficient number of sessions and in the case of early trauma as etiological factor of the chronic depression. We discuss the application of CBASP to other clinical diagnoses, such as borderline and avoidant personality disorder as well as disorders related to substance abuse and thus argue in favor of CBASP as a central model in the treatment of various mental illnesses.

Quantum Speedup for Active Learning Agents

Can quantum mechanics help us build intelligent learning agents? A defining signature of intelligent behavior is the capacity to learn from experience. However, a major bottleneck for agents to learn in real-life situations is the size and complexity of the corresponding task environment. Even in a moderately realistic environment, it may simply take too long to rationally respond to a given situation. If the environment is impatient, allowing only a certain time for a response, an agent may then be unable to cope with the situation and to learn at all. Here, we show that quantum physics can help and provide a quadratic speedup for active learning as a genuine problem of artificial intelligence. This result will be particularly relevant for applications involving complex task environments.

This review is an attempt to untangle the complexity of transtibial prosthetic socket fit and perhaps find some indication of whether a particular prosthetic socket type might be best for a given situation. In addition, we identified knowledge gaps, thus providing direction for possible future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using medical subject headings and standard key words to search for articles in relevant databases. No restrictions were made on study design and type of outcome measure used. From the obtained search results (n = 1,863), 35 articles were included. The relevant data were entered into a predefined data form that included the Downs and Black risk of bias assessment checklist. This article presents the results from the systematic review of the quantitative outcomes (n = 27 articles). Trends indicate that vacuum-assisted suction sockets improve gait symmetry, volume control, and residual limb health more than other socket designs. Hydrostatic sockets seem to create less inconsistent socket fittings, reducing a problem that greatly influences outcome measures. Knowledge gaps exist in the understanding of clinically meaningful changes in socket fit and its effect on biomechanical outcomes. Further, safe and comfortable pressure thresholds under various conditions should be determined through a systematic approach.

Violent ideations occur more frequently in individuals with mental health problems. They may be of interest in clinical contexts as possible indicators of dangerousness, as corollaries of mental health problems, as candidate treatment targets and as potentially playing a role in perpetuation or onset of symptoms. In spite of their relevance to mental health, some fundamental questions about their place within the broader landscape of mental health problems remain unanswered. To provide a basic characterisation of the relations between violent ideations and dimensions of mental health and provide a foundation for future research in this area we factor analysed a measure of violent ideations and an omnibus measure of mental health dimensions in a normative sample of 1306 youth (at age 17). Results supported a separate dimension of violent ideations with a small to moderate correlation with five other dimensions of mental health: internalising, prosociality, ADHD, indirect/proactive aggression, and physical/reactive aggression. Controlling for comorbidity among mental health dimensions, all but ADHD had unique relations with violent ideations. This suggests that violent ideations are potentially of broad relevance to mental health and related behaviours and there should be a greater research effort aimed at understanding their possible role in mental health.

Within the context of a globalising agenda for genetic research where 'global health' is increasingly seen as necessarily informed by and having to account for genomics, the focus on rare genetic diseases is becoming prominent. Drawing from ethnographic research carried out separately by both authors in Brazil, this paper examines how an emerging focus on two different arenas of rare genetic disease, cancer genetics and a class of degenerative neurological diseases known as Ataxias, is subject to and a product of the dynamics of inclusion and exclusion as this concerns participation in research and access to health care. It examines how in these different cases 'rarenesss' has been diversely situated and differently politicised and how clinicians, patients and their families grapple with the slippery boundaries between research, rights to health and the limits of care, therapy or prevention. It illustrates how attention to rare genetic disease in Brazil emerges at the intersection of a particular history of genetic research and public health infrastructure, densely complicated feedback loops between clinical care and research, patient mobilisation around the 'judicialisation' of health and recent state legislation regarding rare disease in Brazil. It highlights the relevance of local configurations in the way rare genetic disease is being made relevant for and by different communities.
[Coping strategies used by the family of a patient with acute fulminant hepatitis].

In the holistic care to the patient, the family should be an important part because its members are also affected by the situation. Therefore, nursing work should be directed to both the individual and his environment, being of great help to identify family's needs in order to meet their specific needs accurately. Also in the process of recovery the family goes through several stages of coping, each of them have its own characteristics and nurses' interventions should be adapted to them. The aim of this paper is to evidence the importance of caring for the family, identifying the stages of coping, recognizing their needs and identifying relevant care. For this, a clinical case of a family with a relative hospitalised in an intensive care unit because of an acute fulminant hepatitis was developed. The instruments used to carry out the analysis of the case are: family's needs described by Leske et al., coping stages identified by Kubler-Ross, and ways of coping scale developed by Lazarus and Folkman. Nurses have a relevant role due to their close contact with people, this helps to become a factor which facilitates the interaction of patient and family within the hospital environment. A holistic approach of nursing care involves assessing the needs of families to develop strategies for effective interventions.
Practical inquiry/theory in nursing.
Stevenson, Chris
2005-04-01
This paper explores a social constructionist, pragmatist approach to inquiry and theory-building with a view to exploring its relevance for nursing as a practical discipline. Positivist and postpositivist inquiry approaches in practical disciplines have produced "detached" theories that lack relevance for everyday practice and so sustain the theory-practice gap. Both meta- and mid-range theories tend to see practice as fixed or fixable rather than being enacted in a state of flux. Practical inquiry and theory are described structurally and as co-dependent processes. The research process is sensitive to the influence of context and consists of construction rather than capture. Practical theory is judged in terms of whether it helps people to "go on with" their lives. Practical inquiry/practical theory is superimposed on a previous nursing study in the field of mental health to illustrate how it can account for the processes of clinical research. In particular, the illustration demonstrates the surrender of researcher objectivity in the interests of collaborative understanding that occurs with practical inquiry/theory. Shared meaning arises as rich constructs of the research situation are developed that point to future possibilities for action for all those engaged in the research process. Practical inquiry/theory offers the means to conduct cogent, collaborative, developmental research, although further "trying out" is required.
The Experience of Caregivers Living with Cancer Patients: A Systematic Review and Meta-Synthesis
LeSeure, Peeranuch; Chongkham-ang, Supaporn
2015-01-01
The objectives of this meta-synthesis were to: (1) explore the experience of caregivers who were caring for cancer patients, including their perceptions and responses to the situation; and (2) describe the context and the phenomena relevant to the experience. Five databases were used: CINAHL, MEDLINE, Academic Search, Science Direct, and a Thai database known as the Thai Library Integrated System (ThaiLIS). Three sets of the context of the experience and the phenomena relevant to the experience were described. The contexts were (1) having a hard time dealing with emotional devastation; (2) knowing that the caregiving job was laborious; and (3) knowing that I was not alone. The phenomenon showed the progress of the caregivers’ thoughts and actions. A general phenomenon of the experience—balancing my emotion—applied to most of the caregivers; whereas, more specific phenomenon—keeping life as normal as possible and lifting life above the illness—were experienced by a lesser number of the caregivers. This review added a more thorough explanation of the issues involved in caregiving for cancer patients. A more comprehensive description of the experience of caregiving was described. The findings of this review can be used to guide clinical practice and policy formation in cancer patient care. PMID:26610573
Registered Nurses working together with family members of older people.
Weman, Karin; Fagerberg, Ingegerd
2006-03-01
The aim of the study was to reach a more profound understanding, through looking at nurses' working situation, of those factors that influence how nurses are able to work together with family members of older people living in nursing homes or similar facilities. Working with the care of older people as a Registered Nurse provides a varied job with many challenges. Nurses have to co-operate with family members of those in community health care. Co-operation is important and necessary for all involved. Nurses working in elder care in a geographically defined area received a questionnaire with three open-ended questions, on the difficulties and/or problems involved with working together with family members, and the positive or negative aspects of this co-operation. Analysis was carried out using the latent content analysis method. Three themes, problems within the system, interaction with families and caring in nursing work, are presented with categories and their subcategories. The nurses wanted their superior to be a nurse so that their working situation would be better understood. Appreciation from their superior and family members was also a very important part of their work as nurses in community health care. The frequent changes and the lack of time in the work of elder care often put nurses under considerable psychological pressure. For the most part family members are a resource for the elder, but sometimes they will avoid contact, which will make co-operating difficult. Registered Nurses and family members are dependent on each other in their care of the elder. Relevance to clinical practice. More attention should be paid to the working situation of Registered Nurses in community health care, and their ability to work together with family members of older people.

We investigated how increases in task-relevant information affect human decision-making performance, situation awareness (SA), and trust in a simulated command-and-control (C2) environment. Increased information is often associated with an improvement of SA and decision-making performance in networked organizations. However, previous research suggests that increasing information without considering the task relevance and the presentation can impair performance. We used a simulated C2 task across two experiments. Experiment 1 varied the information volume provided to individual participants and measured the speed and accuracy of decision making for task performance. Experiment 2 varied information volume and information reliability provided to two participants acting in different roles and assessed decision-making performance, SA, and trust between the paired participants. In both experiments, increased task-relevant information volume did not improve task performance. In Experiment 2, increased task-relevant information volume reduced self-reported SA and trust, and incorrect source reliability information led to poorer task performance and SA. These results indicate that increasing the volume of information, even when it is accurate and task relevant, is not necessarily beneficial to decision-making performance. Moreover, it may even be detrimental to SA and trust among team members. Given the high volume of available and shared information and the safety-critical and time-sensitive nature of many decisions, these results have implications for training and system design in C2 domains. To avoid decrements to SA, interpersonal trust, and decision-making performance, information presentation within C2 systems must reflect human cognitive processing limits and capabilities. © 2016, Human Factors and Ergonomics Society.
Adaptive Memory: Is There a Reproduction-Processing Effect?
Seitz, Benjamin M; Polack, Cody W; Miller, Ralph R
2017-12-14
Like all biological systems, human memory is likely to have been influenced by evolutionary processes, and its abilities have been subjected to selective mechanisms. Consequently, human memory should be primed to better remember information relevant to one's evolutionary fitness. Supporting this view, participants asked to rate words based on their relevance to an imaginary survival situation better recall those words (even the words rated low in relevancy) than the same words rated with respect to non-survival situations. This mnemonic advantage is called the "survival-processing effect," and presumably it was selected for because it contributed to evolutionary fitness. The same reasoning suggests that there should be an advantage for recall of information that has been rated for relevancy to reproduction and/or mate seeking, although little evidence has existed to assess this proposition. We used an experimental design similar to that in the original survival-processing effect study (Nairne, Thompson, & Pandeirada, 2007) and across 3 experiments tested several newly designed scenarios to determine whether a reproduction-processing effect could be found in an ancestral environment, a modern mating environment, and an ancestral environment in which the emphasis was on raising offspring as opposed to finding a mate. Our results replicated the survival-processing effect but provided no evidence of a reproduction-processing effect when the scenario emphasized finding a mate. However, when rating items on their relevancy to raising one's offspring in an ancestral environment, a mnemonic advantage comparable to that of the survival-processing effect was found.

Reflections on relevance: Psychotherapy and Psychosomatics in 2004.
Balon, Richard
2005-01-01
Relevance of an article is a highly desirable yet hardly predictable quality at the time of its publication. Article relevance is frequently measured by the impact factor of the journal where the article is published. Furthermore, impact factor, citation index and citation analysis are used as a measure of research progress and scientific wealth of a nation. The wisdom and significance of this approach to relevance is debatable and thus discussed here. In 2004, Psychotherapy and Psychosomatics published a variety of articles which, in the author's view, are clinically relevant. Several selected clinically relevant issues reviewed in this article include: the conceptualization of fibromyalgia as a stress disorder; the psychosocial impact and psychosocial interventions in cancer; the impact of alexithymia on patient care; the possible relationship between depression and nutrition (namely intake of folate and pyridoxal phosphate); the significance of hypercoagulability in panic-like anxiety; the questionable value of single isomer drugs, and the relevance and adequacy of clinimetrics versus psychometrics in clinical research. The reviewed issues seem to be relevant to clinical practice, research or both, but also to our critical thinking, and the critical review of the developments in psychiatry and psychology.

Prostate-specific membrane antigen (PSMA) is a promising target in prostate cancer. Recently, we started the first-in-human treatment with an α-radionuclide-labeled PSMA ligand. Although the case series is still ongoing, we here report in advance about two patients in highly challenging clinical situations who showed a complete response to 225 Ac-PSMA-617 therapy. 68 Ga-PSMA-11 PET/CT validated the presence of the PSMA-positive tumor phenotype. A 100-kBq activity of 225 Ac-PSMA-617 per kilogram of body weight was administered bimonthly. Prostate-specific antigen response and hematologic toxicity were measured at least every 4 wk. Restaging was performed with 68 Ga-PSMA-11 PET/CT. Both patients experienced a prostate-specific antigen decline to below the measurable level and showed a complete response on imaging. No relevant hematologic toxicity was observed. Xerostomia was the only mentionable clinical side effect. Targeted α-therapy with 225 Ac-PSMA-617, although still experimental, obviously has strong potential to significantly benefit advanced-stage prostate cancer patients. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.
Antioxidants in Translational Medicine
Schmidt, Harald H.H.W.; Stocker, Roland; Vollbracht, Claudia; Paulsen, Gøran; Riley, Dennis
2015-01-01
Abstract Significance: It is generally accepted that reactive oxygen species (ROS) scavenging molecules or antioxidants exert health-promoting effects and thus their consumption as food additives and nutraceuticals has been greatly encouraged. Antioxidants may be beneficial in situations of subclinical deficiency and increased demand or acutely upon high-dose infusion. However, to date, there is little clinical evidence for the long-term benefit of most antioxidants. Alarmingly, recent evidence points even to health risks, in particular for supplements of lipophilic antioxidants. Recent Advances: The biological impact of ROS depends not only on their quantities but also on their chemical nature, (sub)cellular and tissue location, and the rates of their formation and degradation. Moreover, ROS serve important physiological functions; thus, inappropriate removal of ROS may cause paradoxical reductive stress and thereby induce or promote disease. Critical Issues: Any recommendation on antioxidants must be based on solid clinical evidence and patient-relevant outcomes rather than surrogate parameters. Future Directions: Such evidence-based use may include site-directed application, time-limited high dosing, (functional) pharmacological repair of oxidized biomolecules, and triggers of endogenous antioxidant response systems. Ideally, these approaches need guidance by patient stratification through predictive biomarkers and possibly imaging modalities. Antioxid. Redox Signal. 23, 1130–1143. PMID:26154592
Ultrasonic propulsion of kidney stones.
May, Philip C; Bailey, Michael R; Harper, Jonathan D
2016-05-01
Ultrasonic propulsion is a novel technique that uses short bursts of focused ultrasonic pulses to reposition stones transcutaneously within the renal collecting system and ureter. The purpose of this review is to discuss the initial testing of effectiveness and safety, directions for refinement of technique and technology, and opinions on clinical application. Preclinical studies with a range of probes, interfaces, and outputs have demonstrated feasibility and consistent safety of ultrasonic propulsion with room for increased outputs and refinement toward specific applications. Ultrasonic propulsion was used painlessly and without adverse events to reposition stones in 14 of 15 human study participants without restrictions on patient size, stone size, or stone location. The initial feasibility study showed applicability in a range of clinically relevant situations, including facilitating passage of residual fragments following ureteroscopy or shock wave lithotripsy, moving a large stone at the ureteropelvic junction with relief of pain, and differentiating large stones from a collection of small fragments. Ultrasonic propulsion shows promise as an office-based system for transcutaneously repositioning kidney stones. Potential applications include facilitating expulsion of residual fragments following ureteroscopy or shock wave lithotripsy, repositioning stones prior to treatment, and repositioning obstructing ureteropelvic junction stones into the kidney to alleviate acute renal colic.

Clinical ethics and values: how do norms evolve from practice?
Spranzi, Marta
2013-02-01
Bioethics laws in France have just undergone a revision process. The bioethics debate is often cast in terms of ethical principles and norms resisting emerging social and technological practices. This leads to the expression of confrontational attitudes based on widely differing interpretations of the same principles and values, and ultimately results in a deadlock. In this paper I would like to argue that focusing on values, as opposed to norms and principles, provides an interesting perspective on the evolution of norms. As Joseph Raz has convincingly argued, "life-building" values and practices are closely intertwined. Precisely because values have a more indeterminate meaning than norms, they can be cited as reasons for action by concerned stakeholders, and thus can help us understand how controversial practices, e.g. surrogate motherhood, can be justified. Finally, norms evolve when the interpretations of the relevant values shift and cause a change in the presumptions implicit in the norms. Thus, norms are not a prerequisite of the ethical solution of practical dilemmas, but rather the outcome of the decision-making process itself. Struggling to reach the right decision in controversial clinical ethics situations indirectly causes social and moral values to change and principles to be understood differently.
Morinda citrifolia (Noni) fruit--phytochemistry, pharmacology, safety.
Potterat, Olivier; Hamburger, Matthias
2007-03-01
Products derived from Noni fruit (Morinda citrifolia) have been commercialised in the USA since the 1990s and are increasingly distributed all over the world. A large number of beneficial effects have been claimed for Noni. Fruit juice of Noni has been approved as a Novel Food by the European Commission in 2003. This article reviews current knowledge on the phytochemistry, pharmacology, safety aspects of Noni fruit and Noni-derived products, and health-related claims and benefits. The knowledge on the chemical composition of Noni fruit has considerably increased over recent years. A number of in vitro and, to a certain extent, in vivo studies demonstrate a range of potentially beneficial effects. However, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present. Based on a toxicological assessment, Noni juice was considered as safe. Due to recent reports of cases of hepatotoxicity, the safety issue has been re-examined in Europe. While the European Food Safety Authority sees no link between adverse effects on liver and consumption of Noni juice, a continuing monitoring of the situation is desirable and some vigilance advised.
Dual Role of GM-CSF as a Pro-Inflammatory and a Regulatory Cytokine: Implications for Immune Therapy
Bhattacharya, Palash; Budnick, Isadore; Singh, Medha; Thiruppathi, Muthusamy; Alharshawi, Khaled; Elshabrawy, Hatem; Holterman, Mark J.
2015-01-01
Granulocyte macrophage colony stimulating factor (GM-CSF) is generally recognized as an inflammatory cytokine. Its inflammatory activity is primarily due its role as a growth and differentiation factor for granulocyte and macrophage populations. In this capacity, among other clinical applications, it has been used to bolster anti-tumor immune responses. GM-CSF-mediated inflammation has also been implicated in certain types of autoimmune diseases, including rheumatoid arthritis and multiple sclerosis. Thus, agents that can block GM-CSF or its receptor have been used as anti-inflammatory therapies. However, a review of literature reveals that in many situations GM-CSF can act as an anti-inflammatory/regulatory cytokine. We and others have shown that GM-CSF can modulate dendritic cell differentiation to render them “tolerogenic,” which, in turn, can increase regulatory T-cell numbers and function. Therefore, the pro-inflammatory and regulatory effects of GM-CSF appear to depend on the dose and the presence of other relevant cytokines in the context of an immune response. A thorough understanding of the various immunomodulatory effects of GM-CSF will facilitate more appropriate use and thus further enhance its clinical utility. PMID:25803788
Noninvasive testing of asymptomatic bilateral hilar adenopathy
DOE Office of Scientific and Technical Information (OSTI.GOV)
Carr, P.L.; Singer, D.E.; Goldenheim, P.
1990-03-01
The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify manymore » patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy.« less
Safety of MRI with metallic middle ear implants.
Tohme, Souheil M; Karkas, Alexandre A; Romanos, Bassam H
2003-01-01
Investigation of the effects of magnetic resonance fields on commonly used metallic middle ear implants. Nine middle ear prostheses (seven containing stainless steel and two made of pure gold used as control) were tested in vitro and one stainless steel stapedectomy prosthesis was tested on a cadaveric temporal bone. Each metallic prosthesis was placed in an empty Petri dish and introduced into a 1.5-tesla (T) magnetic resonance imaging (MRI) unit. Most of the prostheses were then placed in a water-filled Petri dish and reintroduced into the MRI unit. Eventual in vitro displacement was assessed visually by two means. In situ testing was done by implanting a piston in a cadaveric temporal bone and performing MR sequences ; any possible displacement was then assessed by CT scan and under microscopic vision. None of the prostheses was displaced in the empty Petri dish. However, while in the water-filled Petri dish, three of these moved with the flux. The implanted piston in the temporal bone did not move. The displacement of three of the prostheses in water is not relevant in real clinical situations. MRI can thus be considered safe in usual clinical settings, as far as our studied implants are concerned.

Several existing conceptual models and psychological interventions address or emphasize the role of emotion dysregulation in eating disorders. The current article uses Gratz and Roemer’s (2004) multidimensional model of emotion regulation and dysregulation as a clinically relevant framework to review the extant literature on emotion dysregulation in anorexia nervosa (AN) and bulimia nervosa (BN). Specifically, the dimensions reviewed include: (1) the flexible use of adaptive and situationally appropriate strategies to modulate the duration and/or intensity of emotional responses, (2) the ability to successfully inhibit impulsive behavior and maintain goal-directed behavior in the context of emotional distress, (3) awareness, clarity, and acceptance of emotional states, and (4) the willingness to experience emotional distress in the pursuit of meaningful activities. The current review suggests that both AN and BN are characterized by broad emotion regulation deficits, with difficulties in emotion regulation across the four dimensions found to characterize both AN and BN, although a small number of more specific difficulties may distinguish the two disorders. The review concludes with a discussion of the clinical implications of the findings, as well as a summary of limitations of the existing empirical literature and suggestions for future research.

[Using of cell biocomposite material in tissue engineering of the urinary bladder].

2017-06-01
In a systematic review, to present an overview of the current situation in the field of tissue engineering of urinary bladder related to the use of cell lines pre-cultured on matrices. The selection of eligible publications was conducted according to the method described in the article Glybochko P.V. et al. "Tissue engineering of urinary bladder using acellular matrix." At the final stage, studies investigating the application of matrices with human and animal cell lines were analyzed. Contemporary approaches to using cell-based tissue engineering of the bladder were analyzed, including the formation of 3D structures from several types of cells, cell layers and genetic modification of injected cells. The most commonly used cell lines are urothelial cells, mesenchymal stem cells and fibroblasts. The safety and efficacy of any types of composite cell structures used in the cell-based bladder tissue engineering has not been proven sufficiently to warrant clinical studies of their usefulness. The results of cystoplasty of rat bladder are almost impossible to extrapolate to humans; besides, it is difficult to predict possible side effects. For the transition to clinical trials, additional studies on relevant animal models are needed.
Diagnostic value of clinical tests for degenerative rotator cuff disease in medical practice.

To assess the diagnostic value of clinical tests for degenerative rotator cuff disease (DRCD) in medical practice. Patients with DRCD were prospectively included. Eleven clinical tests of the rotator cuff have been done. One radiologist performed ultrasonography (US) of the shoulder. Results of US were expressed as normal tendon, tendinopathy or full-thickness tear (the reference). For each clinical test and each US criteria, sensitivity, specificity, negative predictive value and positive predictive value, accuracy, negative likelihood ratio (NLR) and positive likelihood ratio (PLR) were calculated. Clinical relevance was defined as PLR ≥2 and NLR ≤0.5. For 35 patients (39 shoulders), Jobe (PLR: 2.08, NLR: 0.31) and full-can (2, 0.5) test results were relevant for diagnosis of supraspinatus tears and resisted lateral rotation (2.42, 0.5) for infraspinatus tears, with weakness as response criteria. The lift-off test (8.50, 0.27) was relevant for subscapularis tears with lag sign as response criteria. Yergason's test (3.7, 0.41) was relevant for tendinopathy of the long head of the biceps with pain as a response criterion. There was no relevant clinical test for diagnosis of tendinopathy of supraspinatus, infraspinatus or subscapularis. Five of 11 clinical tests were relevant for degenerative rotator cuff disease.

Clinical Queries filters were developed to improve the retrieval of high-quality studies in searches on clinical matters. The study objective was to determine the yield of relevant citations and physician satisfaction while searching for diagnostic and treatment studies using the Clinical Queries page of PubMed compared with searching PubMed without these filters. Forty practicing physicians, presented with standardized treatment and diagnosis questions and one question of their choosing, entered search terms which were processed in a random, blinded fashion through PubMed alone and PubMed Clinical Queries. Participants rated search retrievals for applicability to the question at hand and satisfaction. For treatment, the primary outcome of retrieval of relevant articles was not significantly different between the groups, but a higher proportion of articles from the Clinical Queries searches met methodologic criteria (p=0.049), and more articles were published in core internal medicine journals (p=0.056). For diagnosis, the filtered results returned more relevant articles (p=0.031) and fewer irrelevant articles (overall retrieval less, p=0.023); participants needed to screen fewer articles before arriving at the first relevant citation (p<0.05). Relevance was also influenced by content terms used by participants in searching. Participants varied greatly in their search performance. Clinical Queries filtered searches returned more high-quality studies, though the retrieval of relevant articles was only statistically different between the groups for diagnosis questions. Retrieving clinically important research studies from Medline is a challenging task for physicians. Methodological search filters can improve search retrieval.

The Objective Structured Clinical Examination (OSCE) has become widely accepted as a strategy for assessing clinical competence in nursing and midwifery education and training. There is a dearth of information, however, on the OSCE procedure from the perspective of midwifery students. In particular, there is an absence of an objective quantification of midwifery students' attitudes towards the OSCE. The objective of this study is to report the conduct and findings of a survey of midwifery students' attitudes towards a Lactation and Infant Feeding OSCE and to consider these attitudes in the context of the international literature and the empirical evidence base. A descriptive survey design using an 18-item Likert (1 to 5 point) scale was used to capture the relevant data. Potential participants were 3rd year midwifery students who had undertaken a Lactation and Infant Feeding OSCE (n=35) in one School of Nursing & Midwifery in the Republic of Ireland. Survey responses were analysed using the Statistical Package for the Social Sciences Version 18. Thirty-three students completed the survey providing a 94% response rate. Midwifery students' attitudes towards individual aspects of the OSCE varied. Overall, midwifery students were neutral/unsure of the OSCE as a strategy for assessing clinical competence (mean 3.3). Most agreed that the examiner made them feel at ease (mean 3.94). Contrastingly this does not appear to appease student nerves and stress as the majority agreed that the OSCE evokes nervousness (mean 4.27) and stress (mean 4.30). Midwifery students, overall, disagreed that the OSCE reflected real life clinical situations (mean 2.48). Midwifery students were neutral/unsure that the OSCE provided an opportunity to show their practical skills (mean 3.36). The findings of this study identified that midwifery students were neutral/unsure of the OSCE as a strategy for assessing clinical competence. This has relevance for OSCE development at the authors' institution. The results suggest the need to explore further why students responded in this way. This will assist to develop this OSCE further to ensure that it becomes a positive assessment process for midwifery students and for student learning as they progress through their midwifery education and training.

A problem encountered by medical examiners is that they have to assess injuries that have already been medically treated. Thus, they have to base their reports on clinical forensic examinations performed hours or days after an injury was sustained, or even base their assessment solely on information gleaned from medical files. In both scenarios, the forensic examiner has to rely heavily on the first responder's documentation of the original injury pattern. Medical priority will be to immediately treat a patient's injuries, and the first responder may, in addition, initially be unaware of a possibly criminal origin of an injury. As a result, the documentation of injuries is frequently of limited value for forensic purposes. This situation could be improved if photographic records were briefly made of injuries before they were treated. German-language medicolegal, criminal, and photography journals and books were selectively searched with the help of PubMed and other databases. In addition, the authors' experiences in creating and evaluating photographic records for clinical forensic use were assessed. This paper is an aid to creating photographic records of sufficient quality for forensic purposes. The options provided by digital photography in particular make this endeavor feasible even in a clinical setting. In addition, our paper illuminates some technical aspects of creating and archiving photographic records for forensic use, and addresses possible error sources. With the requisite technical background knowledge, injuries can be photographically recorded to forensic standards during patient care.

One of the most important factors affecting the development of honey bee colonies is infectious diseases such as American foulbrood (AFB) caused by the spore forming Gram-positive bacterium Paenibacillus larvae. Colony inspections for AFB clinical symptoms are time consuming. Moreover, diseased cells in the early stages of the infection may easily be overlooked. In this study, we investigated whether it is possible to determine the sanitary status of a colony based on analyses of different materials collected from the hive. We analysed 237 bee samples and 67 honey samples originating from 71 colonies situated in 13 apiaries with clinical AFB occurrences. We tested whether a difference in spore load among bees inside the whole hive exists and which sample material related to its location inside the hive was the most appropriate for an early AFB diagnosis based on the culture method. Results indicated that diagnostics based on analysis of honey samples and bees collected at the hive entrance are of limited value as only 86% and 83%, respectively, of samples from AFB-symptomatic colonies were positive. Analysis of bee samples collected from the brood nest, honey chamber, and edge frame allowed the detection of all colonies showing AFB clinical symptoms. Microbiological analysis showed that more than one quarter of samples collected from colonies without AFB clinical symptoms were positive for P. larvae. Based on these results, we recommend investigating colonies by testing bee samples from the brood nest, edge frame or honey chamber for P. larvae spores.
Clinical relevance of diagnosing COPD by fixed ratio or lower limit of normal: a systematic review.
van Dijk, Wouter D; Gupta, Nisha; Tan, Wan C; Bourbeau, Jean
2014-02-01
Different spirometric criteria in diagnosing COPD have been advocated by different groups, debilitating adequate diagnosis and treatment of COPD. We reviewed the clinical relevance of fixed ratio and lower limit of normal (LLN) in diagnosing COPD and explored if modifying factors may affect their clinical relevance. Two reviewers independently searched PubMed and Embase for papers that compared both criteria on any clinically relevant outcome, published before June 1st, 2012, without any language restriction. Two reviewers independently extracted the study characteristics, including study design, population characteristics and diagnostic criteria used, and summarized the results of clinical relevance. Study quality was assessed by scoring forms for bias and level of evidence. Of 394 studies retrieved, 11 studies were included, with a median of 1,258 participants. Although both criteria appeared related with various clinically relevant outcomes, we were unable to prefer one criterion over the other, with various performances of the criteria for different outcomes. Should the criteria disagree on diagnosis, an alternative diagnosis should be suspected, in particular in those (elderly) with less severe airflow limitation for whom the LLN appears a better criterion. The fixed ratio appears to perform better in subjects with more severe airflow limitation. In diagnosing COPD, severity of airflow limitation appears an important factor for choosing whether the fixed ratio or LLN. Disagreement between the criteria is suggestive for an alternative diagnosis. Future studies on clinical relevance should further reveal the criterion of choice, in order to improve adequate diagnosis and consequent treatments.

Motion Artefacts in MRI: a Complex Problem with Many Partial Solutions
Zaitsev, Maxim; Maclaren, Julian.; Herbst, Michael
2015-01-01
Subject motion during magnetic resonance imaging (MRI) has been problematic since its introduction as a clinical imaging modality. While sensitivity to particle motion or blood flow can be used to provide useful image contrast, bulk motion presents a considerable problem in the majority of clinical applications. It is one of the most frequent sources of artefacts. Over 30 years of research have produced numerous methods to mitigate or correct for motion artefacts, but no single method can be applied in all imaging situations. Instead, a ‘toolbox’ of methods exists, where each tool is suitable for some tasks, but not for others. This article reviews the origins of motion artefacts and presents current mitigation and correction methods. In some imaging situations, the currently available motion correction tools are highly effective; in other cases, appropriate tools still need to be developed. It seems likely that this multifaceted approach will be what eventually solves the motion sensitivity problem in MRI, rather than a single solution that is effective in all situations. This review places a strong emphasis on explaining the physics behind the occurrence of such artefacts, with the aim of aiding artefact detection and mitigation in particular clinical situations.

Memory may have evolved to preserve information processed in terms of its fitness-relevance. Based on the assumption that the human mind comprises different fitness-relevant adaptive mechanisms contributing to survival and reproductive success, we compared alternative fitness-relevant processing scenarios with survival processing. Participants rated words for relevancy to fitness-relevant and control conditions followed by a delay and surprise recall test (Experiment 1a). Participants recalled more words processed for their relevance to a survival situation. We replicated these findings in an online study (Experiment 2) and a study using revised fitness-relevant scenarios (Experiment 3). Across all experiments, we did not find a mnemonic benefit for alternative fitness-relevant processing scenarios, questioning assumptions associated with an evolutionary account of remembering. Based on these results, fitness-relevance seems to be too wide-ranging of a construct to account for the memory findings associated with survival processing. We propose that memory may be hierarchically sensitive to fitness-relevant processing instructions. We encourage future researchers to investigate the underlying mechanisms responsible for survival processing effects and work toward developing a taxonomy of adaptive memory. PMID:23585858

To evaluate outcomes of a residential community reintegration program 3 years after treatment on independent living, societal participation, emotional well-being, and quality of life in patients with chronic acquired brain injury and psychosocial problems hampering societal participation. A follow-up assessment 3 years after treatment was compared with the 1-year follow-up assessment in a prospective cohort study. A tertiary rehabilitation center for acquired brain injury. Of the 67 patients assessed at the 1-year follow-up, 63 subjects (94%; 42 men; mean age at admission to treatment 24.7y; mean time postonset 5.1y) were available at the 3-year follow-up and taken into account in the analyses. A structured residential treatment program directed at improving independence in domestic life, work, leisure time, and social interactions. Community Integration Questionnaire, Employability Rating Scale, living situation, school, work situation, work hours, Center for Epidemiological Studies-Depression scale, and the World Health Organization Quality of Life Scale Abbreviated (5 scales). There were no significant differences for any of the outcome measures between the 1-year and 3-year follow-up assessment. These results indicate that the established significant and clinically relevant improvements after a residential community reintegration program remain stable in the long term.

To achieve well-being in patients in Palliative Care is required to know which are the most common symptoms, which are the drugs used for relief, which are the routes of administration of drugs that are suitable, how effective the drugs are and what incompatibilities, interactions and adverse effects occur. The aim of this article is to review the relevant issues in the management of the drugs commonly used by nursing in Palliative Care and presenting recommendations to clinical practice. Management interventions drugs for nurses in Palliative Care recommended by the scientific literature after a search of Scopus, CINAHL, Medline, PubMed, UpToDate and Google Scholar are selected. The oral route is the choice for patients in palliative situation and subcutaneous route when the first is not available. The symptoms, complex, intense and moody, should be systematically reevaluated by the nurse, to predict when a possible decompensation of it needing extra dose of medication. Nurses must be able to recognize the imbalance of well-being and act quickly and effectively, to get relief to some unpleasant situations for the patient as the pain symptoms, dyspnea or delirium. For the proper administration of rescue medication, the nurse should know the methods of symptomatic evaluation, pharmacokinetics and pharmacodynamics of drugs, the time intervals to elapse between different rescues and nccocc rocnnnco t thocm
[Use of virtual reality in forensic psychiatry. A new paradigm?].
Fromberger, P; Jordan, K; Müller, J L
2014-03-01
For more than 20 years virtual realities (VR) have been successfully used in the assessment and treatment of psychiatric disorders. The most important advantages of VR are the high ecological validity of virtual environments, the entire controllability of virtual stimuli in the virtual environment and the capability to induce the sensation of being in the virtual environment instead of the physical environment. VRs provide the opportunity to face the user with stimuli and situations which are not available or too risky in reality. Despite these advantages VR-based applications have not yet been applied in forensic psychiatry. On the basis of an overview of the recent state-of-the-art in VR-based applications in general psychiatry, the article demonstrates the advantages and possibilities of VR-based applications in forensic psychiatry. Up to now only preliminary studies regarding the VR-based assessment of pedophilic interests exist. These studies demonstrate the potential of ecologically valid VR-based applications for the assessment of forensically relevant disorders. One of the most important advantages is the possibility of VR to assess the behavior of forensic inpatients in crime-related situations without endangering others. This provides completely new possibilities not only regarding the assessment but also for the treatment of forensic inpatients. Before utilizing these possibilities in the clinical practice exhaustive research and development will be necessary. Given the high potential of VR-based applications, this effort would be worth it.
Posttraumatic growth in bereaved parents: A multidimensional model of associated factors.
Albuquerque, Sara; Narciso, Isabel; Pereira, Marco
2018-03-01
Although the death of a child is a devastating event, recent evidence shows that personal growth is a relevant outcome of parents' grief. This study aimed to examine the factors associated with posttraumatic growth (PTG) and to propose a multidimensional model consisting of sociodemographic, situational, and intrapersonal and interpersonal factors. A sample (N = 197; 89.8% female; mean age = 39.44 years) of bereaved parents completed the Post-Traumatic Growth Inventory-Short Form, the 14-Item Resilience Scale, the Continuing Bonds Scale, and the Dyadic Coping Inventory. The final model consisted of sociodemographic, situational, intrapersonal, and interpersonal factors of PTG, which accounted for 36.7% of the variance. Higher levels of PTG were generally associated with female sex, younger age of the child, higher levels of resilience, higher levels of internalized continuing bonds (i.e., internal representation of the child, maintaining psychological proximity), and higher levels of stress communication by the partner (communicating the stress experience and requesting emotional or practical support). In clinical practice, health professionals assisting bereaved parents should pay attention to men and parents of older children, who might be at higher risk of difficulties in developing PTG. Additionally, promoting a more internalized bond with the child, resilience and dyadic coping, especially stress communication, can constitute important therapeutic goals.

Effect of sweet orange aroma on experimental anxiety in humans.
Goes, Tiago Costa; Antunes, Fabrício Dias; Alves, Péricles Barreto; Teixeira-Silva, Flavia
2012-08-01
The objective of this study was to evaluate the potential anxiolytic effect of sweet orange (Citrus sinensis) aroma in healthy volunteers submitted to an anxiogenic situation. Forty (40) male volunteers were allocated to five different groups for the inhalation of sweet orange essential oil (test aroma: 2.5, 5, or 10 drops), tea tree essential oil (control aroma: 2.5 drops), or water (nonaromatic control: 2.5 drops). Immediately after inhalation, each volunteer was submitted to a model of anxiety, the video-monitored version of the Stroop Color-Word Test (SCWT). Psychologic parameters (state-anxiety, subjective tension, tranquilization, and sedation) and physiologic parameters (heart rate and gastrocnemius electromyogram) were evaluated before the inhalation period and before, during, and after the SCWT. Unlike the control groups, the individuals exposed to the test aroma (2.5 and 10 drops) presented a lack of significant alterations (p>0.05) in state-anxiety, subjective tension and tranquillity levels throughout the anxiogenic situation, revealing an anxiolytic activity of sweet orange essential oil. Physiologic alterations along the test were not prevented in any treatment group, as has previously been observed for diazepam. Although more studies are needed to find out the clinical relevance of aromatherapy for anxiety disorders, the present results indicate an acute anxiolytic activity of sweet orange aroma, giving some scientific support to its use as a tranquilizer by aromatherapists.
Training in clinical forensic medicine in the UK--perceptions of current regulatory standards.
Stark, Margaret M; Norfolk, Guy A
2011-08-01
As clinical forensic medicine (CFM) is not currently recognised as a speciality in the UK there are no nationally agreed mandatory standards for training forensic physicians in either general forensic (GFM) or sexual offence medicine (SOM). The General Medical Council (GMC), the medical regulator in the UK, has issued clear standards for training in all specialities recommending that "trainees must be supported to acquire the necessary skills and experience through induction, effective educational supervision, an appropriate workload and time to learn". In order to evaluate the current situation in the field of clinical forensic medicine, doctors who have recently (within the last two years) started working in the field "trainees" (n = 38), and trainers (n = 61) with responsibility for clinical and educational supervision of new trainees, were surveyed by questionnaire to gather their perceptions of how the relevant GMC standards are being met in initial on-the-job training. Telephone interviews were performed with eleven doctors working as clinical or medical directors to determine their views. It is clear that currently the quality of training in CFM is sub-standard and inconsistent and that the published standards, as to the minimum requirement for training that must be met by post-graduate medical and training providers at all levels, are not being met. The Faculty of Forensic and Legal Medicine (FFLM) needs to set explicit minimum standards which will comply with the regulator and work to pilot credentialing for forensic physicians. A number of recommendations are made for urgent FFLM development. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

Medical students build clinical knowledge on the grounds of previously obtained basic knowledge. The study aimed to evaluate the competency of third year medical students to interpret biochemically based clinical scenarios using knowledge and skills gained during year 1 and 2 of undergraduate medical training. Study was conducted on year 3 MBBS students at AIMST University, Malaysia. Clinical scenarios (25) were constructed and administered to student volunteers, making sure at least one question from each system of year 2 was represented. Feedback was obtained on a five-point Likert scale regarding perception of learning biochemistry in MBBS year 1 versus 2. Mean score of test was 18 (72.11%). Performance was comparatively better in questions related to topics learnt in year 1 and reinforced in year 2 compared to those learnt for first time in year 2. In the feedback obtained, 31% strongly agreed and 56% agreed understanding the subject was helped more by learning biochemistry in year 2 than in year 1. Likewise, 36% strongly agreed and 56% agreed appreciating the importance of biochemistry in patient diagnosis was helped more by learning biochemistry in year 2 than year 1. Thirty one percent strongly agreed and 54% agreed that year 1 biochemistry would have been more relevant if case discussions were done simultaneously. Students retain basic science subjects better and appreciate the importance of basic sciences in patient diagnosis if they are reinforced in the context of clinical situations. © 2016 The International Union of Biochemistry and Molecular Biology.
Not Your Same Old Story: New Rules for Thematic Apperceptive Techniques (TATs).
Jenkins, Sharon Rae
2017-01-01
Stories told about pictures have been used for both research and clinical practice since the beginning of modern personality assessment. However, with the growing science-practice gap, these thematic apperceptive techniques (TATs) have been used differently in those 2 venues. Scientific validation is presumptively general, but clinical application is idiographic and situation-specific. A bridge is needed. The manualized human-scored narrative analysis systems discussed here are valuable scientist-practitioner tools, but they require a validation literature to support further research publication, maintain their role in clinical training, and justify clinicians' reimbursement by third-party payers. To facilitate wider understanding of manualized TAT methodologies, this article addresses long-standing criticisms of TAT reliability and proposes some strategic solutions to the measurement error problem for both researchers and clinicians, including analyzing person-situation interactions, purposeful situation sampling for within-storyteller comparisons, and uses of small samples. The new rules for TATs include conceptual and methodological standards that researchers should aim to meet and report, reviewers should apply to manuscripts, and clinical assessors can use to analyze their own data and justify third-party payment.
Measuring situation awareness in emergency settings: a systematic review of tools and outcomes

2014-01-01
Background Nontechnical skills have an impact on health care outcomes and improve patient safety. Situation awareness is core with the view that an understanding of the environment will influence decision-making and performance. This paper reviews and describes indirect and direct measures of situation awareness applicable for emergency settings. Methods Electronic databases and search engines were searched from 1980 to 2010, including CINAHL, Ovid Medline, Pro-Quest, Cochrane, and the search engine, Google Scholar. Access strategies included keyword, author, and journal searches. Publications identified were assessed for relevance, and analyzed and synthesized using Oxford evidence levels and the Critical Appraisal Skills Programme guidelines in order to assess their quality and rigor. Results One hundred and thirteen papers were initially identified, and reduced to 55 following title and abstract review. The final selection included 14 papers drawn from the fields of emergency medicine, intensive care, anesthetics, and surgery. Ten of these discussed four general nontechnical skill measures (including situation awareness) and four incorporated the Situation Awareness Global Assessment Technique. Conclusion A range of direct and indirect techniques for measuring situation awareness is available. In the medical literature, indirect approaches are the most common, with situation awareness measured as part of a nontechnical skills assessment. In simulation-based studies, situation awareness in emergencies tends to be suboptimal, indicating the need for improved training techniques to enhance awareness and improve decision-making.

The aim of this work was to examine how the presence of inapplicable items might change the factor structure of the 1984 Ways of Coping Questionnaire by Lazarus and Folkman. The Spanish version of the Ways of Coping Questionnaire was administered to 156 subjects with university degrees. The 95 women and 61 men whose ages were from 18 and 45 years (M = 27.8, SD = 12.1) were of middle socioeconomic status. All were residents of Buenos Aires. To study whether relevant items modify the factor structure of the Ways of Coping Questionnaire, two factor analyses were carried out, one with items rated as not relevant (Item Mean) and the other with the same items rated as not chosen. In both factor analyses, principal axes method and oblimin rotation were performed, and five factors were considered. Congruence indexes were performed. Analysis showed that not choosing an item because it does not coincide with one's behavior or ideas is not the same as not selecting that item because it does not apply to the current threatening situation. Lack of discrimination between situations when analyzing data leads to a distorted interpretation of the way in which the subject actually behaves or copes with the situation.
Online responsibility: bad samaritanism and the influence of internet mediation.
Polder-Verkiel, Saskia E
2012-03-01
In 2008 a young man committed suicide while his webcam was running. 1,500 people apparently watched as the young man lay dying: when people finally made an effort to call the police, it was too late. This closely resembles the case of Kitty Genovese in 1964, where 39 neighbours supposedly watched an attacker assault and did not call until it was too late. This paper examines the role of internet mediation in cases where people may or may not have been good Samaritans and what their responsibilities were. The method is an intuitive one: intuitions on the various potentially morally relevant differences when it comes to responsibility between offline and online situations are examined. The number of onlookers, their physical nearness and their anonymity have no moral relevance when it comes to holding them responsible. Their perceived reality of the situation and ability to act do have an effect on whether we can hold people responsible, but this doesn't seem to be unique to internet mediation. However the way in which those factors are intrinsically connected to internet mediation does seem to have a diminishing effect on responsibility in online situations. © The Author(s) 2010.

Insights from clinical research completed during the west Africa Ebola virus disease epidemic
Rojek, Amanda; Horby, Peter; Dunning, Jake
2018-01-01
The west Africa Ebola virus disease (EVD) epidemic was extraordinary in scale. Now that the epidemic has ended, it is a relevant time to examine published studies with direct relevance to clinical care and, more broadly, to examine the implications of the clinical research response mounted. Clinically relevant research includes literature detailing risk factors for and clinical manifestations of EVD, laboratory and other investigation findings in patients, experimental vaccine and therapeutic clinical trials, and analyses of survivor syndrome. In this Review, we discuss new insights from patient-oriented research completed during the west Africa epidemic, identify ongoing knowledge gaps, and suggest priorities for future research.

A major aim of Systems Pharmacology is to understand clinically relevant mechanisms of action (MOA) of drugs and to use this knowledge in order to optimize therapy. To enable this mission it is necessary to obtain knowledge on how in vitro testable insights translate into clinical efficacy. Mathematical modeling and data integration are essential components to achieve this goal. Two modeling philosophies are prevalent, each of which in isolation is not sufficient to achieve the above described: In a 'top-down' approach, a minimal pharmacokinetic-pharmacodynamic (PK-PD) model is derived from- and fitted to available clinical data. This model may lack interpretability in terms of mechanisms and may only be predictive for scenarios already covered by the data used to derive it. A 'bottom-up' approach builds on mechanistic insights derived from in vitro/ex vivo experiments, which can be conducted under controlled conditions, but may not be fully representative for the in vivo/clinical situation. In this work, we employ both approaches side-by-side to predict the clinical potency (IC 50 values) of the nucleoside reverse transcriptase inhibitors (NRTIs) lamivudine, emtricitabine and tenofovir. In the 'top-down' approach, this requires to establish the dynamic link between the intracellularly active NRTI-triphosphates (which exert the effect) and plasma prodrug PK and to subsequently link this composite PK model to viral kinetics. The 'bottom-up' approach assesses inhibition of reverse transcriptase-mediated viral DNA polymerization by the intracellular, active NRTI-triphosphates, which has to be brought into the context of target cell infection. By using entirely disparate sets of data to derive and parameterize the respective models, our approach serves as a means to assess the clinical relevance of the 'bottom-up' approach. We obtain very good qualitative and quantitative agreement between 'top-down' vs. 'bottom-up' predicted IC 50 values, arguing for the validity of the 'bottom-up' approach. We noted, however, that the 'top-down' approach is strongly dependent on the sparse and noisy intracellular pharmacokinetic data. All in all, our work provides confidence that we can translate in vitro parameters into measures of clinical efficacy using the 'bottom-up' approach. This may allow to infer the potency of various NRTIs in inhibiting e.g. mutant viruses, to distinguish sources of interaction of NRTI combinations and to assess the efficacy of different NRTIs for repurposing, e.g. for pre-exposure prophylaxis.

Multi-robot missions are a challenge for operators in terms of workload and situational awareness. These operators have to receive data from the robots, extract information, understand the situation properly, make decisions, generate the adequate commands, and send them to the robots. The consequences of excessive workload and lack of awareness can vary from inefficiencies to accidents. This work focuses on the study of future operator interfaces of multi-robot systems, taking into account relevant issues such as multimodal interactions, immersive devices, predictive capabilities and adaptive displays. Specifically, four interfaces have been designed and developed: a conventional, a predictive conventional, a virtual reality and a predictive virtual reality interface. The four interfaces have been validated by the performance of twenty-four operators that supervised eight multi-robot missions of fire surveillance and extinguishing. The results of the workload and situational awareness tests show that virtual reality improves the situational awareness without increasing the workload of operators, whereas the effects of predictive components are not significant and depend on their implementation.

Situated learning in translation research training: academic research as a reflection of practice
Risku, Hanna
2016-01-01
ABSTRACT Situated learning has become a dominant goal in the translation classroom: translation didactics is being developed in a learner-, situation- and experience-based direction, following constructivist and participatory teaching philosophies. However, the explicit use of situated approaches has, so far, not been the centre of attention in translation theory teaching and research training. As a consequence, translation theory often remains unconnected to the skills learned and topics tackled in language-specific translation teaching and the challenges experienced in real-life translation practice. This article reports on the results of an exploratory action research project into the teaching of academic research skills in translation studies at Master’s level. The goal of the project is to develop and test possibilities for employing situated learning in translation research training. The situatedness perspective has a double relevance for the teaching project: the students are involved in an authentic, ongoing research project, and the object of the research project itself deals with authentic translation processes at the workplace. Thus, the project has the potential to improve the expertise of the students as both researchers and reflective practitioners. PMID:27499805
Methodological Consequences of Situation Specificity: Biases in Assessments
Patry, Jean-Luc
2011-01-01
Social research is plagued by many biases. Most of them are due to situation specificity of social behavior and can be explained using a theory of situation specificity. The historical background of situation specificity in personality social psychology research is briefly sketched, then a theory of situation specificity is presented in detail, with as centerpiece the relationship between the behavior and its outcome which can be described as either “the more, the better” or “not too much and not too little.” This theory is applied to reliability and validity of assessments in social research. The distinction between “maximum performance” and “typical performance” is shown to correspond to the two behavior-outcome relations. For maximum performance, issues of reliability and validity are much easier to be solved, whereas typical performance is sensitive to biases, as predicted by the theory. Finally, it is suggested that biases in social research are not just systematic error, but represent relevant features to be explained just as other behavior, and that the respective theories should be integrated into a theory system.

Identifying Opportunities for Vertical Integration of Biochemistry and Clinical Medicine.
Wendelberger, Karen J.; Burke, Rebecca; Haas, Arthur L.; Harenwattananon, Marisa; Simpson, Deborah
1998-01-01
Objectives: Retention of basic science knowledge, as judged by National Board of Medical Examiners' (NBME) data, suffers due to lack of apparent relevance and isolation of instruction from clinical application, especially in biochemistry. However, the literature reveals no systematic process for identifying key biochemical concepts and associated clinical conditions. This study systematically identified difficult biochemical concepts and their common clinical conditions as a critical step towards enhancing relevance and retention of biochemistry.Methods: A multi-step/ multiple stakeholder process was used to: (1) identify important biochemistry concepts; (2) determine students' perceptions of concept difficulty; (3) assess biochemistry faculty, student, and clinical teaching scholars' perceived relevance of identified concepts; and (4) identify associated common clinical conditions for relevant and difficult concepts. Surveys and a modified Delphi process were used to gather data, subsequently analyzed using SPSS for Windows.Results: Sixteen key biochemical concepts were identified. Second year medical students rated 14/16 concepts as extremely difficult while fourth year students rated nine concepts as moderately to extremely difficult. On average, each teaching scholar generated common clinical conditions for 6.2 of the 16 concepts, yielding a set of seven critical concepts and associated clinical conditions.Conclusions: Key stakeholders in the instructional process struggle to identify biochemistry concepts that are critical, difficult to learn and associated with common clinical conditions. However, through a systematic process beginning with identification of concepts and associated clinical conditions, relevance of basic science instruction can be enhanced.

Introduction: Nowadays students' opinion is considered as a necessary factor to evaluate quality in universities. This study was performed to evaluate the nursing students' satisfaction about their field of study. Methods: The research population in this study consists of all the students of nursing studying at the second to fourth year of university (72 students). The data were collected from all the studied population. Data collection instrument was a research questionnaire. In this cross-sectional research, nursing students' satisfaction (72 students) in 6 major topics (situation of educational environment, situation of clinical environment, trainers, social image, relation to colleagues and management) was studied. The data were analyzed in SPSS, version 14, using quantitative variables and descriptive statistics including frequency distribution tables and diagrams. Results: The findings indicated that 83.3% of the students had little satisfaction as to the situation of educational environment, 47.2% about situation of clinical environment, 41.7% concerning the theoretical educational method by professors, and 41.7% as to the method of clinical education by clinical trainers. Also 47.2% were not that satisfied with the method of evaluation by the school professors, 80.6% with the method of relationship with colleagues and also 62.5% with the nursing social image. Moreover, findings indicated that 33.3% of the participants in this research were dissatisfied with the method of evaluation by clinical trainers and 50% with the method of nursing management. Conclusion: In the present study, most students had little satisfaction concerning their field of study. So it is necessary to make an attempt for continuous development of quality services.

The data were analyzed in SPSS, version 14, using quantitative variables and descriptive statistics including frequency distribution tables and diagrams. The findings indicated that 83.3% of the students had little satisfaction as to the situation of educational environment, 47.2% about situation of clinical environment, 41.7% concerning the theoretical educational method by professors, and 41.7% as to the method of clinical education by clinical trainers. Also 47.2% were not that satisfied with the method of evaluation by the school professors, 80.6% with the method of relationship with colleagues and also 62.5% with the nursing social image. Moreover, findings indicated that 33.3% of the participants in this research were dissatisfied with the method of evaluation by clinical trainers and 50% with the method of nursing management. In the present study, most students had little satisfaction concerning their field of study. So it is necessary to make an attempt for continuous development of quality services.

To examine the current status of professional neuropsychology in Spain, with particular focus on the areas of professional training, current work situation, evaluation and diagnostic practice, rehabilitation, teaching, and research. Three hundred and thirty-nine self-identified professionals in neuropsychology from Spain completed an online survey between July and December of 2013. Respondents had an average age of 35.8 years and 77% were women. Ninety-seven percent of the respondents identified as psychologists; 82% of the sample had a master's degree, and 33% a doctoral degree. The majority (91%) received their neuropsychological training at a graduate level; 88% engaged in neuropsychological evaluation, 59% in rehabilitation, 50% in research, and 40% in teaching. Average number of hours per week dedicated to work in neuropsychology was 29.7, with 28% of the respondents reporting working in hospitals, 17% in not-for-profit rehabilitation centers, 15% in universities, and 14% in private clinics. Clinicians primarily work with individuals with stroke, traumatic brain injury, and dementia. The top perceived barriers to development of neuropsychology in Spain included lack of clinical and academic training opportunities, and negative attitude toward professional collaboration. The field of neuropsychology in Spain is young and rapidly growing. There is a need to regulate professional neuropsychology, improve graduate curricula, enhance existing clinical training, develop professional certification programs, validate and create normative data for existing neuropsychological tests, and create new, culturally relevant instruments.

Clinical risk includes any undesirable situation or operational factor that may have negative consequences for patient safety or capable of causing an adverse event (AE). The AE, intentional or unintentionally, may be related to the human factor, that is, medical errors (MEs). Therefore, the importance of the health-care risk management is a current and relevant issue on the agenda of many public and private institutions. The objective of the management has been evolving from the identification of AE to the assessment of cost-effective and efficient measures that improve the quality control through monitoring. Consequently, the goal of this paper is to propose a Key Risk Indicator (KRI) that enhances the advancement of the health-care management system. Thus, the application of the Value at Risk (VaR) concept in combination to the Loss Distribution Approach (LDA) is proved to be a proactive tool, within the frame of balanced scorecard (BSC), in health organizations. For this purpose, the historical events recorded in the Algo-OpData ® database (Algorithmics Inc., Toronto, ON, Canada, IBM, Armonk, NY, USA) have been used. The analysis highlights the importance of risk in the financials outcomes of the sector. The results of paper show the usefulness of the Clinical-VaR to identify and monitor the risk and sustainability of the implemented controls.

kV radiotherapy treatment calculations are based on flat, homogenous, full-scatter reference conditions. However, clinical treatments often include surface irregularities and inhomogeneities, causing uncertainty. Therefore, confirmation of actual delivered doses in vivo is valuable. The current study evaluates, and implements, radiochromic film and micro silica bead TLD for in vivo kV dosimetry. The kV energy and dose response of EBT3 film and silica bead TLD was established and uncertainty budgets determined. In vivo dosimetry measurements were made for a consecutive series of 30 patients using the two dosimetry systems. Energy dependent calibration factors were required for both dosimetry systems. The standard uncertainty estimate for in vivo measurement with film was 1.7% and for beads was 1.5%. The mean measured dose was -2.1% for film and -2.6% for beads compared to prescription. Deviations up to -9% were found in cases of large surface irregularity, or with underlying air cavities or bone. Dose shielding by beads could be clinically relevant at low kV energies and superficial depths. Both film and beads may be used to provide in vivo verification of delivered doses in kV radiotherapy, particularly for complex situations that are not well represented by standard reference condition calculations.
