This clinical focus article contains a detailed description of how to build effective teams that use interprofessional collaborative practice (IPCP) with special-education professionals, speech-language pathologists, and families of children with severe disabilities. This clinical focus article provides information on using the essential elements of team building and IPCP to provide quality care to families who have children with severe disabilities. The 6 essential elements for team building are described, with suggestions for including families in each: goal-setting, roles and responsibilities, effective and efficient process, communication and interpersonal relationships, collaborative problem solving, and evaluation. The 4 competency domains of IPCP are embedded into each of the team-building elements to demonstrate how teams can implement IPCP. A case study illustrates the difficulty one parent experienced working with a team across the 6 essential team-building elements when seeking communication services for her child with severe disabilities.

Knowledge, instruction and behavioural change: building a framework for effective eczema education in clinical practice.

PubMed

Thompson, Deryn Lee; Thompson, Murray John

2014-11-01

A discussion on the reasons educational interventions about eczema, by nurses, are successful, with the subsequent development of a theoretical framework to guide nurses to become effective patient educators. Effective child and parent education is the key to successful self-management of eczema. When diagnosed, children and parents should learn to understand the condition through clear explanations, seeing treatment demonstrations and have ongoing support to learn practical skills to control eczema. Dermatology nurses provide these services, but no one has proposed a framework of the concepts underpinning their successful eczema educational interventions. A discussion paper. A literature search of online databases was undertaken utilizing terms 'eczema OR atopic dermatitis', 'education', 'parent', 'nurs*', 'framework', 'knowledge', motivation', in Scopus, CINAHL, Web of Science, Medline and Pubmed. Limits were English language and 2003-2013. The framework can inform discussion on child and parent education, provide a scaffold for future research and guide non-specialist nurses, internationally, in providing consistent patient education about eczema. Founded on an understanding of knowledge, the framework utilizes essential elements of cognitive psychology and social cognitive theory leading to successful self-management of eczema. This framework may prove useful as a basis for future research in child and parent education, globally, in the healthcare community. A framework has been created to help nurses understand the essential elements of the learning processes at the foundation of effective child and parent education. The framework serves to explain the improved outcomes reported in previous nurse-led eczema educational interventions. © 2014 The Authors.

A rapid review of treatment literacy materials for tuberculosis patients.

PubMed

Brumwell, A; Noyes, E; Kulkarni, S; Lin, V; Becerra, M C; Yuen, C M

2018-03-01

To assess available treatment literacy materials for patients undergoing treatment for tuberculosis (TB). We conducted a rapid review by searching the US Centers for Disease Control's Find TB Resources website and the websites of health departments and TB-focused organizations. We included English-language documents intended to educate TB patients about anti-tuberculosis treatment. We evaluated the format, readability, and content of documents, and audience. We defined 12 essential content elements based on those previously identified as facilitating human immunodeficiency virus treatment literacy. Of the 205 documents obtained, 45 were included in our review. The median reading grade level was 7 (IQR 5-8). The median number of essential content elements present was 6 (IQR 4-8), with the most comprehensive document containing 11 of the 12 elements. Only two documents were written for children with TB or their care givers, and two for patients with drug-resistant TB. Many documents contained paternalistic and non-patient-centered language. We found few examples of comprehensive, patient-centered documents. Work is needed to achieve consensus as to the essential elements of TB treatment literacy and to create additional materials for children, patients with drug-resistant TB, and those with lower literacy levels.

Self-management education interventions for patients with cancer: a systematic review.

PubMed

Howell, Doris; Harth, Tamara; Brown, Judy; Bennett, Cathy; Boyko, Susan

2017-04-01

This systematic review was intended to identify the effectiveness and inclusion of essential components of self-management education interventions to support patients with cancer in developing the skills needed for effective self-management of their disease and the acute or immediate, long-term, and late harmful effects of treatments. Self-management education interventions were included if they were randomized controlled trials (RCTs) containing at least one of the eight core elements outlined by the research team. A systematic search was conducted in Ovid MEDLINE (2005 through April 2015), Embase (2005 to 2015, week 15), the Cochrane Database of Systematic Reviews (Issue 4, April 2015), CINAHL (2005 to 2015) and PsychINFO (2005 to 2015). Keywords searched include 'self-management patient education' or 'patient education'. Forty-two RCTs examining self-management education interventions for patients with cancer were identified. Heterogeneity of interventions precluded meta-analysis, but narrative qualitative synthesis suggested that self-management education interventions improve symptoms of fatigue, pain, depression, anxiety, emotional distress and quality of life. Results for specific combinations of core elements were inconclusive. Very few studies used the same combinations of core elements, and among those that did, results were conflicting. Thus, conclusions as to the components or elements of self-management education interventions associated with the strength of the effects could not be assessed by this review. Defining the core components of cancer self-management education and the fundamental elements for inclusion in supporting effective self-management will be critical to ensure consistent and effective provision of self-management support in the cancer system.

PubMed

Peterson, Eleanor B; Calhoun, Aaron W; Rider, Elizabeth A

2014-09-01

With increased recognition of the importance of sound communication skills and communication skills education, reliable assessment tools are essential. This study reports on the psychometric properties of an assessment tool based on the Kalamazoo Consensus Statement Essential Elements Communication Checklist. The Gap-Kalamazoo Communication Skills Assessment Form (GKCSAF), a modified version of an existing communication skills assessment tool, the Kalamazoo Essential Elements Communication Checklist-Adapted, was used to assess learners in a multidisciplinary, simulation-based communication skills educational program using multiple raters. 118 simulated conversations were available for analysis. Internal consistency and inter-rater reliability were determined by calculating a Cronbach's alpha score and intra-class correlation coefficients (ICC), respectively.

Clinical wisdom: the essential foundation of "good" nursing care.

PubMed

Haggerty, Lois A; Grace, Pamela

2008-01-01

Clinical wisdom, an essential foundation of nursing care that provides for the "good" of individual patients while taking into account the common good, is a concept that is difficult to define and comprehend. However, understanding what constitutes clinical wisdom is essential for the education of the types of nurses who are most likely to provide leadership that is consistent with the goals of nursing as outlined in the 2005 Code of Ethics for Nurses of the International Council of Nurses and the 2001 Code of Ethics for Nurses With Interpretive Statements of the American Nurses Association. The three key elements of wisdom, derived from the psychology and philosophy literature, are (1) balancing and providing for the good of another and the common good, (2) the use of intellect and affect in problem solving, and (3) the demonstration of experience-based tacit knowing in problematic situations. We conceptualized clinical wisdom as a more specific variant of general wisdom by examining how the core elements described can be linked to wisdom for nursing practice. In doing so, the nature of clinical wisdom is clarified and strategies are suggested to assist nurse educators in developing wise nurses.

Ecopedagogy as an element of citizenship education: The dialectic of global/local spheres of citizenship and critical environmental pedagogies

NASA Astrophysics Data System (ADS)

Misiaszek, Greg William

2016-10-01

Emerging from popular education movements in Latin America, ecopedagogy is a critical environmental pedagogy which focuses on understanding the connections between social conflict and environmentally harmful acts carried out by humans. These connections are often politically hidden in education. Ecopedagogy, while being pluralistic, is in its essence defined as a critical, transformative environmental pedagogy centred on increasing social and environmental justice. Its ultimate aim is to find a sustainable balance between the conflicting goals of diverse notions of human progress and environmental wellbeing. This article is based on two comparative research projects. The first was a qualitative study on ecopedagogical models involving 31 expert ecopedagogues in Argentina, Brazil and the Appalachian region of the United States. They were asked for their perspectives on how successful ecopedagogy can be defined within the contexts in which they taught and conducted research. The second study analysed how 18 international expert scholars of citizenship and/or environmental pedagogy from six world continents regarded the ways in which citizenship intersects with environmental issues and the pedagogies of both in an increasingly globalised world, with specific focus on Global Citizenship Education. Results from the first study indicate the following two needs for effective environmental pedagogies: (1) for there to be an ecopedagogical paradigm shift in environmental teaching and research; and (2) for ecopedagogy to be an essential element of citizenship education (and vice versa). This article examines how conflicting processes of globalisation both help and hinder in achieving such a paradigm shift by decentring traditional nation-state citizenship. Results from the second study indicate how critical teaching within and between different spheres of citizenship (e.g. local, national, global, and planetary citizenship) is essential for ecopedagogy (and the ecopedagogical element).

Knowledge, instruction and behavioural change: building a framework for effective eczema education in clinical practice

PubMed Central

Thompson, Deryn Lee; Thompson, Murray John

2014-01-01

Aims A discussion on the reasons educational interventions about eczema, by nurses, are successful, with the subsequent development of a theoretical framework to guide nurses to become effective patient educators. Background Effective child and parent education is the key to successful self-management of eczema. When diagnosed, children and parents should learn to understand the condition through clear explanations, seeing treatment demonstrations and have ongoing support to learn practical skills to control eczema. Dermatology nurses provide these services, but no one has proposed a framework of the concepts underpinning their successful eczema educational interventions. Design A discussion paper. Data Sources A literature search of online databases was undertaken utilizing terms ‘eczema OR atopic dermatitis’, ‘education’, ‘parent’, ‘nurs*’, ‘framework’, ‘knowledge’, motivation’, in Scopus, CINAHL, Web of Science, Medline and Pubmed. Limits were English language and 2003–2013. Implications for Nursing The framework can inform discussion on child and parent education, provide a scaffold for future research and guide non-specialist nurses, internationally, in providing consistent patient education about eczema. Conclusion Founded on an understanding of knowledge, the framework utilizes essential elements of cognitive psychology and social cognitive theory leading to successful self-management of eczema. This framework may prove useful as a basis for future research in child and parent education, globally, in the healthcare community. A framework has been created to help nurses understand the essential elements of the learning processes at the foundation of effective child and parent education. The framework serves to explain the improved outcomes reported in previous nurse-led eczema educational interventions. PMID:25312442

Essential and non-essential elements in natural vegetation in southern Norway: contribution from different sources.

PubMed

Nordløkken, Marit; Berg, Torunn; Flaten, Trond Peder; Steinnes, Eiliv

2015-01-01

Concentrations of essential and non-essential elements in five widespread species of natural boreal vegetation were studied with respect to seasonal variation and contribution from different sources. The plant species included in the study were Betula pubescens, Sorbus aucuparia, Vaccinium myrtillus, Vaccinium uliginosum, Calluna vulgaris and Deschampsia flexuosa. Concentrations of elements essential to plants remained essentially constant or decreased slightly throughout the growing season. Concentrations of most non-essential elements increased or tended to increase on a dry mass basis from June to July as well as from July to September. The increasing trend for these elements was observed for all species except C. vulgaris. Principal component analysis (PCA) of the material indicated a common source for many of the non-essential elements; Sc, Ti, V, Ga, As, Y, Sb, lanthanides, Pb, Bi, and U, i.e. both elements presumably of geogenic origin and elements associated with trans-boundary air pollution. Uptake by plant roots appeared to be the main source of nutrient elements as well as some non-essential elements. Copyright © 2014 Elsevier B.V. All rights reserved.

Student satisfaction as an element of education quality monitoring in innovative higher education institution

NASA Astrophysics Data System (ADS)

Razinkina, Elena; Pankova, Ludmila; Trostinskaya, Irina; Pozdeeva, Elena; Evseeva, Lidiya; Tanova, Anna

2018-03-01

Topicality of the research is confirmed by increasing student involvement into the educational process, when not only the academic staff and administration participate in the improvement of higher education institution's activity, but also education customers - students. This adds a new dimension to the issue of monitoring education quality and student satisfaction with higher education. This issue echoes the ideas of M. Weber about the relationship between such components as cognitive motivation, personal development and student satisfaction with higher education. Besides, it is essential to focus on the approach of R. Barnet to defining the quality of education with the emphasis on a priority of development of an educational institution as the system that meets customers' needs. Monitoring student satisfaction with education quality has become an integral part of the educational process not only in a number of European universities, which have used this monitoring for decades, but also in Russian universities, which are interested in education quality improvement. Leading universities in Russia, including Peter the Great St. Petersburg Polytechnic University, are implementing policies targeted at increasing student satisfaction with higher education quality. Education quality monitoring as a key element in the system of providing feedback to students contributes greatly to this process.

Learning how to learn using simulation: Unpacking disguised feedback using a qualitative analysis of doctors' telephone talk.

PubMed

Eppich, Walter J; Rethans, Jan-Joost; Dornan, Timothy; Teunissen, Pim W

2018-05-04

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.

We performed an environmental scan of currently available websites providing educational information about rheumatoid arthritis (RA) and evaluated the quality of these websites. We searched three separate search engines, Google, Bing, and Ask.com, on August 27, 2015, using two search terms, "arthritis" and "rheumatoid." Only patient education websites were included. Two independent investigators evaluated the accuracy, completeness, technical elements, design and esthetics, readability, usability, and accessibility of the websites. The navigation experience was also evaluated by an adult training expert. We identified 46 websites. Nearly all websites (98%) provided accurate information. However, no website covered all essential RA topics. Common essential topics not covered included epidemiology, pathogenesis, treatment and disease monitoring, complications, self-management, risks and benefits of treatment, prognosis, treatment adherence, questions for patients to ask their doctors, and costs. For the technical elements, all websites disclosed their ownership, but the date that the content was last updated was mentioned in only 10 websites, ranging from 2007 to 2015. The mean reading level was grade 12.1 (standard deviation ±2.3). Most websites (78%) were easy to navigate but only 33% were friendly for people with visual and/or hearing impairments. The navigation experience was rated fair or poor in 41% of the websites. Current patient information on the Internet does not comprehensively address all educational needs of patients with RA, and is often outdated. The findings from our study highlight potential areas for improvement in online education materials for patients with RA. Copyright © 2017. Published by Elsevier Inc.

Towards optimizing server performance in an educational MMORPG for teaching computer programming

NASA Astrophysics Data System (ADS)

Malliarakis, Christos; Satratzemi, Maya; Xinogalos, Stelios

2013-10-01

Web-based games have become significantly popular during the last few years. This is due to the gradual increase of internet speed, which has led to the ongoing multiplayer games development and more importantly the emergence of the Massive Multiplayer Online Role Playing Games (MMORPG) field. In parallel, similar technologies called educational games have started to be developed in order to be put into practice in various educational contexts, resulting in the field of Game Based Learning. However, these technologies require significant amounts of resources, such as bandwidth, RAM and CPU capacity etc. These amounts may be even larger in an educational MMORPG game that supports computer programming education, due to the usual inclusion of a compiler and the constant client/server data transmissions that occur during program coding, possibly leading to technical issues that could cause malfunctions during learning. Thus, the determination of the elements that affect the overall games resources' load is essential so that server administrators can configure them and ensure educational games' proper operation during computer programming education. In this paper, we propose a new methodology with which we can achieve monitoring and optimization of the load balancing, so that the essential resources for the creation and proper execution of an educational MMORPG for computer programming can be foreseen and bestowed without overloading the system.

2016-12-01

Crops intended for human nutrition and food production containing different essential trace elements, such as copper and zinc, could be contaminated by toxic metals like cadmium and lead. The interrelationship between micronutrients and contaminant trace elements in different cereals was investigated in North-western Italy, where both agricultural and industrial activities are present. Elemental concentrations in sampled cereals were assessed by inductively coupled plasma mass spectrometry (ICP-MS). Rice, oats and barley reached the highest median levels for Al, Cd and Pb content, while corn samples were less contaminated by toxic metals. Regarding essential elements highest median values of Cu and Zn were both found in barley, while Ni median content was higher in oats. Rice had the lowest median levels of essential elements. The correlation study between toxic and essential elements seemed to demonstrate fixed trends in analysed samples, corroborating the importance of a different diet to limit potential adverse effects caused by toxic elements.

Guidelines for evaluating the educational performance of medical school faculty: priming a national conversation.

PubMed

Baldwin, Constance; Chandran, Latha; Gusic, Maryellen

2011-01-01

The academic community needs a sound framework for the promotion and advancement of educators. The Group on Educational Affairs of the Association of American Medical Colleges organized a consensus conference that affirmed the use of five domains for documenting the quantity and quality of scholarly engagement in educational activities: teaching, curriculum, advising/mentoring, educational leadership/administration, and learner assessment. In this article, we offer detailed guidelines to evaluate these five domains of educator performance and the essential elements of scholarly activity. The guidelines are adapted from our developmental educator portfolio template and educator portfolio analysis tool, previously published in MedEdPORTAL. A short tool for educator performance evaluation that summarizes items in the guidelines is proposed for discussion. Our goal in this article is to itemize criteria for systematic faculty evaluation that can be applied in any institutional setting to assist promotion decision makers in their task of evaluating medical school faculty.

2017-11-01

Career planning, decision making about specialty choice, and preparation for residency matching are significant sources of stress for medical students. Attempts have been made to structure and formalize career advising by including it in accreditation standards. There is an expressed need for national guidelines on career advising for medical students. The Future of Medical Education in Canada Postgraduate (FMEC PG) Implementation Project was created to ensure Canadian medical trainees receive the best education possible. From this, a diverse sub-working group (SWG), representing different Canadian regions, was formed to review career advising processes across the country. The SWG developed, through a modified formal consensus methodology, a strategy for medical student career advising that is adaptable to all schools in alignment with existing accreditation standards. The SWG outlined five guiding principles and five essential elements for Canadian universities offering an MD degree with recommendations on how to integrate the elements into each school's career advising system. The five essential elements are a structured approach to career advising, information about available career options, elective guidance, preparation for residency applications, and social accountability. This Perspective endorses the view of the FMEC PG Implementation Project that national guidelines are important to ensure Canadian medical schools are consistently meeting accreditation standards by providing reliable and quality career advising to all medical students. The SWG's position, based on national and provincial feedback, is that these guidelines will stimulate discourse and action regarding the requirements and processes to carry out these recommendations nationwide and share across borders.

The elements of life and medicines

Which elements are essential for human life? Here we make an element-by-element journey through the periodic table and attempt to assess whether elements are essential or not, and if they are, whether there is a relevant code for them in the human genome. There are many difficulties such as the human biochemistry of several so-called essential elements is not well understood, and it is not clear how we should classify elements that are involved in the destruction of invading microorganisms, or elements which are essential for microorganisms with which we live in symbiosis. In general, genes do not code for the elements themselves, but for specific chemical species, i.e. for the element, its oxidation state, type and number of coordinated ligands, and the coordination geometry. Today, the biological periodic table is in a position somewhat similar to Mendeleev's chemical periodic table of 1869: there are gaps and we need to do more research to fill them. The periodic table also offers potential for novel therapeutic and diagnostic agents, based on not only essential elements, but also non-essential elements, and on radionuclides. Although the potential for inorganic chemistry in medicine was realized more than 2000 years ago, this area of research is still in its infancy. Future advances in the design of inorganic drugs require more knowledge of their mechanism of action, including target sites and metabolism. Temporal speciation of elements in their biological environments at the atomic level is a major challenge, for which new methods are urgently needed. PMID:25666066

Diabetes is a community issue: the critical elements of a successful outreach and education model on the U.S.-Mexico border.

PubMed

Ingram, Maia; Gallegos, Gwen; Elenes, JoJean

2005-01-01

Diabetes is reaching epidemic proportions on the U.S.-Mexico Border, and culturally competent diabetes education is not available in many communities. People with diabetes often do not have access to regular medical care, cannot afford medication, and lack the community infrastructure that supports self-management practices. Self-management education and support have great potential to impact diabetes control in this environment. To address this need, partners of the Border Health Strategic Initiative (Border Health iSI!) collaboratively developed a culturally relevant diabetes outreach and education program. The model included a five-week series of free diabetes education classes that assisted participants in gaining the knowledge and skills necessary to be physically active, control diet, monitor blood sugar, take medications, and be aware of complications. Central to the model was the use of community health workers - or promotores de salud - to conduct outreach, participate in patient education, and provide individual support. Program participants achieved significant improvements in self-management behaviors and HbA1c, random blood glucose, and blood pressure levels. Quantitative and qualitative evaluation helped to identify the essential elements of a successful program, including partnership of providers, community diabetes classes, promotores outreach and support, linkage between diabetes education and clinical care, and program evaluation.

Dietary fibres are key elements of healthy and balanced diet. The aim of the present study was to explore consumers' knowledge considering fibre, their role in the purchasing decisions, and the cognition of the currently used as well as the possible information sources to encourage the fibre consumption. A questionnaire survey was conducted with 303 respondents. Knowledge about the fibre sources has showed a kind of uncertainty of the respondents, while knowledge about their possible health effects was relatively profound. Internet appeared as a remarkable information source in the topic; however, results pointed out the importance of education, too. Participants more often consuming foodstuffs rich in fibre, women and respondents over 45 years old showed conscious attitudes regarding fibres. Guidelines and education containing authentic information and practical elements are essential, and as a result, consumers' latent knowledge will appear in their conscious food choice decisions.

The ability to effectively communicate through posters and podium presentations using appropriate visual content and style is essential for health care educators. To offer suggestions for more effective visual elements of posters and podium presentations. We present the experiences of our multidisciplinary publishing group, whose combined experiences and collaboration have provided us with an understanding of what works and how to achieve success when working on presentations and posters. Many others would offer similar advice, as these guidelines are consistent with effective presentation. FINDINGS/SUGGESTIONS: Certain visual elements should be attended to in any visual presentation: consistency, alignment, contrast and repetition. Presentations should be consistent in font size and type, line spacing, alignment of graphics and text, and size of graphics. All elements should be aligned with at least one other element. Contrasting light background with dark text (and vice versa) helps an audience read the text more easily. Standardized formatting lets viewers know when they are looking at similar things (tables, headings, etc.). Using a minimal number of colors (four at most) helps the audience more easily read text. For podium presentations, have one slide for each minute allotted for speaking. The speaker is also a visual element; one should not allow the audience's view of either the presentation or presenter to be blocked. Making eye contact with the audience also keeps them visually engaged. Health care educators often share information through posters and podium presentations. These tips should help the visual elements of presentations be more effective.

There is a rapid increase in the incidence of diabetes mellitus in Saudi Arabia. Diabetes management is an essential constituent to prevent prognosis of diabetes complications. The main objective of this study was to assess diabetes care in primary clinics based on the guidelines of American Diabetes Association (ADA). A retrospective study at King Khaled University Hospitals, Riyadh, Saudi Arabia. A total of 200 patients were randomly selected from the databases of primary care clinics. An evaluation checklist was created based on the ADA treatment guidelines such as medical history, physical examination, laboratory evaluation, and referrals. The result showed that elements achieving the ADA targets for overall care were medical history (44.9%), physical examination (59.6%), laboratory evaluation (36.3%), and referrals (19.3%). The other subelement indicators such as referral to diabetes self-management education clinics (10%), dental examination (2%), HbA1c regular monitoring (33.5%), and blood pressure determination (100%) were documented with adherence to ADA standards. Diabetes management standards are an essential element in the success of the management plan. Most of the elements examined are not in full compliance with the ADA standard. Continues monitoring and self-review are recommended.

More Than One Way to Debrief: A Critical Review of Healthcare Simulation Debriefing Methods.

2016-06-01

Debriefing is a critical component in the process of learning through healthcare simulation. This critical review examines the timing, facilitation, conversational structures, and process elements used in healthcare simulation debriefing. Debriefing occurs either after (postevent) or during (within-event) the simulation. The debriefing conversation can be guided by either a facilitator (facilitator-guided) or the simulation participants themselves (self-guided). Postevent facilitator-guided debriefing may incorporate several conversational structures. These conversational structures break the debriefing discussion into a series of 3 or more phases to help organize the debriefing and ensure the conversation proceeds in an orderly manner. Debriefing process elements are an array of techniques to optimize reflective experience and maximize the impact of debriefing. These are divided here into the following 3 categories: essential elements, conversational techniques/educational strategies, and debriefing adjuncts. This review provides both novice and advanced simulation educators with an overview of various methods of conducting healthcare simulation debriefing. Future research will investigate which debriefing methods are best for which contexts and for whom, and also explore how lessons from simulation debriefing translate to debriefing in clinical practice.

2017-09-01

Participation in alternative payment models has focused efforts to improve outcomes and patient satisfaction while also lowering cost for elective hip and knee replacement. The purpose of this review is to determine if preoperative education classes for elective hip and knee replacement achieve these goals. Recent literature demonstrates that patients who attend education classes prior to surgery have decreased anxiety, better post-operative pain control, more realistic expectations of surgery, and a better understanding of their surgery. As a result, comprehensive clinical pathways incorporating a preoperative education program for elective hip and knee replacement lead to lower hospital length of stay, higher home discharge, lower readmission, and improved cost. In summary, we report convincing evidence that preoperative education classes are an essential element to successful participation in alternative payment models such as the Bundle Payment Care Initiative.

This article, prepared by the Association of Professors of Gynecology and Obstetrics Undergraduate Medical Education Committee, discusses the evolving challenges facing medical educators posed by social media and a new form of professionalism that has been termed e-professionalism. E-professionalism is defined as the attitudes and behaviors that reflect traditional professionalism paradigms but are manifested through digital media. One of the major functions of medical education is professional identity formation; e-professionalism is an essential and increasingly important element of professional identity formation, because the consequences of violations of e-professionalism have escalated from academic sanctions to revocation of licensure. E-professionalism should be included in the definition, teaching, and evaluation of medical professionalism. Curricula should include a positive approach for the proper professional use of social media for learners.

This Perspective endorses the view of the FMEC PG Implementation Project that national guidelines are important to ensure Canadian medical schools are consistently meeting accreditation standards by providing reliable and quality career advising to all medical students. The SWG’s position, based on national and provincial feedback, is that these guidelines will stimulate discourse and action regarding the requirements and processes to carry out these recommendations nationwide and share across borders.

The concentrations of four human essential trace elements [iron (Fe), manganese (Mn), zinc (Zn), chromium (Cr)] and non-essential elements [cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg)] in eighteen animal-based foods including meat, fish, and shellfish collected from markets in Shanghai, China, were analyzed, and the associated human daily intake and uptake considering bioaccessibility were estimated. The mean concentration ranges for eight trace elements measured in the foods were 3.98-131µgg(-1) for Fe, 0.437-18.5µgg(-1) for Mn, 5.47-53.8µgg(-1) for Zn, none detected-0.101µgg(-1) for Cr, 2.88×10(-4)-2.48×10(-2)µgg(-1) for Cd, 1.18×10(-3)-0.747µgg(-1) for Pb, none detected-0.498µgg(-1) for As, and 8.98×10(-4)-6.52×10(-2)µgg(-1) for Hg. The highest mean concentrations of four human essential elements were all found in shellfish. For all the trace elements, the observed mean concentrations are mostly in agreement with the reported values around the world. The total daily intake of trace elements via ingestion of animal-based food via an average Shanghai resident was estimated as 7371µgd(-1) for the human essential elements and 13.0µgd(-1) for the human non-essential elements, but the uptake decreased to 4826µgd(-1) and 6.90µgd(-1), respectively, after trace element bioaccessibility was considered. Livestock and fish for human essential and non-essential elements, respectively, were the main contributor, no matter whether the bioaccessibility was considered or not. Risk estimations showed that the intake and uptake of a signal trace element for an average Shanghai resident via ingestion animal-based foods from Shanghai markets do not exceed the recommended dietary allowance values; consequently, a health risk situation is not indicated.

Most of Earth's terrestrial surface is made up of sloping landscapes. The lateral distribution of topsoil by erosion controls the availability, stock, and persistence of essential elements in the terrestrial ecosystem. Over the last two decades, the role of soil erosion in biogeochemical cycling of essential elements has gained considerable interest from the climate, global change, and biogeochemistry communities after soil erosion and terrestrial sedimentation were found to induce a previously unaccounted terrestrial sink for atmospheric carbon dioxide. More recent studies have highlighted the role of erosion in the persistence of organic matter in soil and in the biogeochemical cycling of elements beyond carbon . Here we synthesize available knowledge and data on how erosion serves as a major driver of biogeochemical cycling of essential elements. We address implications of erosion-driven changes in biogeochemical cycles on the availability of essential elements for primary production, on the magnitude of elemental exports downstream, and on the exchange of greenhouse gases from the terrestrial ecosystem to the atmosphere. Furthermore, we explore fates of eroded material and how terrestrial mass movement events play major roles in modifying Earth's climate.

Taher, A

1999-01-01

Accident management is a concept commonly misunderstood, frequently confused with accident treatment. The situation in the Sinai and the Red Sea makes a broad definition of the term "management" necessary. Management encompasses the whole spectrum: from recognition of the need for a hyperbaric facility, establishing one, education of dive center management, instructors, boat skippers and deck hands, to actual contingency plans set according to the different geographical sites. The essential elements of communication, oxygen first aid, transportation, and actual recompression therapy or other treatments and follow-up must be included. Furthermore, a link to the international organisations involved with diving accident management is an essential and desired backup.

With decreasing global resources, a pervasive critical shortage of skilled health workers, and a growing disease burden in many countries, the need to maximize the effectiveness and efficiency of pre-service education in low-and middle-income countries has never been greater. We performed an integrative review of the literature to analyse factors contributing to quality pre-service education and created a conceptual model that shows the links between essential elements of quality pre-service education and desired outcomes. The literature contains a rich discussion of factors that contribute to quality pre-service education, including the following: (1) targeted recruitment of qualified students from rural and low-resource settings appears to be a particularly effective strategy for retaining students in vulnerable communities after graduation; (2) evidence supports a competency-based curriculum, but there is no clear evidence supporting specific curricular models such as problem-based learning; (3) the health workforce must be well prepared to address national health priorities; (4) the role of the preceptor and preceptors' skills in clinical teaching, identifying student learning needs, assessing student learning, and prioritizing and time management are particularly important; (5) modern, Internet-enabled medical libraries, skills and simulation laboratories, and computer laboratories to support computer-aided instruction are elements of infrastructure meriting strong consideration; and (6) all students must receive sufficient clinical practice opportunities in high-quality clinical learning environments in order to graduate with the competencies required for effective practice. Few studies make a link between PSE and impact on the health system. Nevertheless, it is logical that the production of a trained and competent staff through high-quality pre-service education and continuing professional development activities is the foundation required to achieve the desired health outcomes. Professional regulation, deployment practices, workplace environment upon graduation and other service delivery contextual factors were analysed as influencing factors that affect educational outcomes and health impact. Our model for pre-service education reflects the investments that must be made by countries into programmes capable of leading to graduates who are competent for the health occupations and professions at the time of their entry into the workforce.

Spanish gluten-free rice, cereals with gluten, and pureed baby foods were analysed for essential macro-elements (Ca and Na), essential trace elements (Fe, Cu, Zn, Mn, Se, Cr, Co and Ni) and non-essential trace elements (As, Pb, Cd and Hg) using ICP-MS and AAS. Baby cereals were an excellent source of most of the essential elements (Ca, Fe, Cu, Mn and Zn). Sodium content was high in pureed foods to improve their flavour; fish products were also rich in Se. USA pure baby rice samples had the highest contents of all studied essential elements, showing a different nutrient pattern compared to those of other countries. Mineral fortification was not always properly stated in the labelling of infant foods. Complementary infant foods may also contain significant amounts of contaminants. The contents of Hg and Cd were low enough to guarantee the safety of these infant foods. However, it will be necessary to identify the source and reduce the levels of Pb, Cr and As in Spanish foods. Pure baby rice samples contained too much: Pb in Spain; As in UK; As, Cr and Ni in USA; and Cr and Cd in China.

Creating value-added linkages through creative programming: a partnership for nursing education.

Academic and clinical institutions can effectively collaborate to deliver programs that enhance the educational level of the nursing staff. Creative programming, which offers flexibility and convenience, and a reasonable cost are key elements in the success of a program. Open communication and mutual recognition and respect of the talents, abilities, and values of all developers of the program are essential factors in effective collaborations leading to successful partnerships. Although clear expectations and clarity of functions are important once the partnership has developed, flexibility and a desire to "own" both the problems and the successes of a program are crucial to success.

This chapter describes ongoing action research which is exploring the use of BPMN and a specific toolset - Intalio Designer to capture the “as is” essential process model of part of an overarching large business process within higher education. The chapter contends that understanding the efficacy of the BPMN notation and the notational elements to use is not enough. Instead, the effectiveness of a notation is determined by the notation, the toolset that is being used, and methodological consideration. The chapter presents some of the challenges that are faced in attempting to develop computation independent models in BPMN using toolsets such as Intalio Designer™.

In a rapidly urbanizing world, trace element pollution may represent a threat to human health and wildlife, and it is therefore crucial to assess both exposition levels and associated effects of trace element contamination on urban vertebrates. In this study, we investigated the impact of urbanization on trace element contamination and stress physiology in a wild bird species, the common blackbird (Turdus merula), along an urbanization gradient (from rural to moderately urbanized areas). Specifically, we described the contamination levels of blackbirds by 4 non-essential (Ag, Cd, Hg, Pb) and 9 essential trace elements (As, Co, Cr, Cu, Fe, Mn, Ni, Se, Zn), and explored the putative disrupting effects of the non-essential element contamination on corticosterone levels (a hormonal proxy for environmental challenges). We found that non-essential trace element burden (Cd and Pb specifically) increased with increasing urbanization, indicating a significant trace element contamination even in medium sized cities and suburban areas. Interestingly, the increased feather non-essential trace element concentrations were also associated with elevated feather corticosterone levels, suggesting that urbanization probably constrains birds and that this effect may be mediated by trace element contamination. Future experimental studies are now required to disentangle the influence of multiple urban-related constraints on corticosterone levels and to specifically test the influence of each of these trace elements on corticosterone secretion.

Flanigan, Moira; Heilman, James A; Johnson, Tom; Yarris, Lalena M

2015-11-01

The Accreditation Council for Graduate Medical Education requires that residency programs ensure resident competency in performing safe, effective handoffs. Understanding resident, attending, and nurse perceptions of the key elements of a safe and effective emergency department (ED) handoff is a crucial step to developing feasible, acceptable educational interventions to teach and assess this fundamental competency. The aim of our study was to identify the essential themes of ED-based handoffs and to explore the key cultural and interprofessional themes that may be barriers to developing and implementing successful ED-based educational handoff interventions. Using a grounded theory approach and constructivist/interpretivist research paradigm, we analyzed data from three primary and one confirmatory focus groups (FGs) at an urban, academic ED. FG protocols were developed using open-ended questions that sought to understand what participants felt were the crucial elements of ED handoffs. ED residents, attendings, a physician assistant, and nurses participated in the FGs. FGs were observed, hand-transcribed, audio-recorded and subsequently transcribed. We analyzed data using an iterative process of theme and subtheme identification. Saturation was reached during the third FG, and the fourth confirmatory group reinforced the identified themes. Two team members analyzed the transcripts separately and identified the same major themes. ED providers identified that crucial elements of ED handoff include the following: 1) Culture (provider buy-in, openness to change, shared expectations of sign-out goals); 2) Time (brevity, interruptions, waiting); 3) Environment (physical location, ED factors); 4) Process (standardization, information order, tools). Key participants in the ED handoff process perceive that the crucial elements of intershift handoffs involve the themes of culture, time, environment, and process. Attention to these themes may improve the feasibility and acceptance of educational interventions that aim to teach and assess handoff competency.

Context The ability to effectively communicate through posters and podium presentations using appropriate visual content and style is essential for health care educators. Objectives To offer suggestions for more effective visual elements of posters and podium presentations. Methods We present the experiences of our multidisciplinary publishing group, whose combined experiences and collaboration have provided us with an understanding of what works and how to achieve success when working on presentations and posters. Many others would offer similar advice, as these guidelines are consistent with effective presentation. Findings/Suggestions Certain visual elements should be attended to in any visual presentation: consistency, alignment, contrast and repetition. Presentations should be consistent in font size and type, line spacing, alignment of graphics and text, and size of graphics. All elements should be aligned with at least one other element. Contrasting light background with dark text (and vice versa) helps an audience read the text more easily. Standardized formatting lets viewers know when they are looking at similar things (tables, headings, etc.). Using a minimal number of colors (four at most) helps the audience more easily read text. For podium presentations, have one slide for each minute allotted for speaking. The speaker is also a visual element; one should not allow the audience’s view of either the presentation or presenter to be blocked. Making eye contact with the audience also keeps them visually engaged. Conclusions Health care educators often share information through posters and podium presentations. These tips should help the visual elements of presentations be more effective. PMID:20853236

Human scalp hair samples were collected and used to assess exposure to toxic elements and essential elements in the state of North Carolina, USA using accelerated microwave assisted acid digestion and inductively coupled plasma optical emission spectroscopy (ICP-OES). The figures-of-merit of the ICP-OES were appropriate for elemental analysis in scalp hair with detection limits as low as 0.0001 mg/L for Cd, good linearity (R 2  > 0.9978), and percent recoveries that ranged from 96 to 106% for laboratory-fortified-blanks and 88-112% for sample spike recovery study. The concentrations of essential elements in scalp hair were larger than those of toxic elements, with Ca having the highest average concentration (3080 μg/g, s = 14,500, n = 194). Some of the maximum concentrations observed for As (65 μg/g), Ni (331 μg/g), Cd (2.96 μg/g), and Cr (84.6 μg/g) in individual samples were concerning, however. Samples were statistically analyzed to determine the influence of race, gender, smoking habits, or age on the elemental concentrations in scalp hair. Higher concentrations of essential elements were observed in the scalp hair of Caucasians, females, and non-smokers, and the differences were often significant at a 90% confidence level. Several pairs of essential elements, for example Ca-K, Ca-Mg, and Ca-Zn, were strongly correlated in Caucasian hair but uncorrelated in African-American hair. Similarly, essential elements were strongly correlated in female hair but weakly correlated in male hair. Toxic element pairs (As-Cd, As-Se, Pb-As, and Se-Cd) were strongly correlated in the hair of smokers but uncorrelated in that of non-smokers, suggesting that cigarette smoke is a common source of toxic elements in humans.

Simulation-based education has gained popularity, yet many faculty members feel inadequately prepared to teach using this technique. Fellowship training in medical education exists, but there is little information regarding simulation or formal educational programs therein. In our institution, simulation fellowships were offered by individual clinical departments. We recognized the need for a formal curriculum in educational theory. Kern’s approach to curriculum development was used to develop, implement, and evaluate the Foundational Elements of Applied Simulation Theory (FEAST) curriculum. Needs assessments resulted in a 26-topic curriculum; each biweekly session built upon the previous. Components essential to success included setting goals and objectives for each interactive session and having dedicated faculty, collaborative leadership and administrative support for the curriculum. Evaluation data was collated and analyzed annually via anonymous feedback surveys, focus groups, and retrospective pre-post self-assessment questionnaires. Data collected from 32 fellows over five years of implementation showed that the curriculum improved knowledge, challenged thinking, and was excellent preparation for a career in simulation-based medical education. Themes arising from focus groups demonstrated that participants valued faculty expertise and the structure, practicality, and content of the curriculum. We present a longitudinal simulation educator curriculum that adheres to a well-described framework of curriculum development. Program evaluation shows that FEAST has increased participant knowledge in key areas relevant to simulation-based education and that the curriculum has been successful in meeting the needs of novice simulation educators. Insights and practice points are offered for educators wishing to implement a similar curriculum in their institution. PMID:28280655

Vitamin D, Essential Minerals, and Toxic Elements: Exploring Interactions between Nutrients and Toxicants in Clinical Medicine

PubMed Central

Schwalfenberg, Gerry K.; Genuis, Stephen J.

2015-01-01

In clinical medicine, increasing attention is being directed towards the important areas of nutritional biochemistry and toxicant bioaccumulation as they relate to human health and chronic disease. Optimal nutritional status, including healthy levels of vitamin D and essential minerals, is requisite for proper physiological function; conversely, accrual of toxic elements has the potential to impair normal physiology. It is evident that vitamin D intake can facilitate the absorption and assimilation of essential inorganic elements (such as calcium, magnesium, copper, zinc, iron, and selenium) but also the uptake of toxic elements (such as lead, arsenic, aluminum, cobalt, and strontium). Furthermore, sufficiency of essential minerals appears to resist the uptake of toxic metals. This paper explores the literature to determine a suitable clinical approach with regard to vitamin D and essential mineral intake to achieve optimal biological function and to avoid harm in order to prevent and overcome illness. It appears preferable to secure essential mineral status in conjunction with adequate vitamin D, as intake of vitamin D in the absence of mineral sufficiency may result in facilitation of toxic element absorption with potential adverse clinical outcomes.

The objectives of this study were to determine the profiles of non-essential trace elements in ewes' and goats' milk and manufactured products, such as yoghurt, torba yoghurt and whey, as well as changes in trace element content during Torba yoghurt-making processes. Concentrations of non-essential trace elements in ewe (Awassi) and goat (Damascus) milk and their yoghurt, torba yoghurt and whey were quantitatively determined by simultaneous inductively coupled plasma optical emission spectrometer (ICP-OES), after microwave digestion. Aluminium, antimony, arsenic, boron, beryllium, cadmium, nickel, lead, silver, titanium, thallium and vanadium were determined for both types of milk and their products. Barium was not detected in goats' milk or their products. Among all trace elements, boron was the most abundant and beryllium was least present in milk and the manufactured products. The results showed that goats' and ewes' milk and their manufactured products may be a source of 13 non-essential trace elements.

New Evidence against Chromium as an Essential Trace Element.

Vincent, John B

2017-12-01

Nearly 60 y ago, chromium, as the trivalent ion, was proposed to be an essential element, but the results of new studies indicate that chromium currently can only be considered pharmacologically active and not an essential element. Regardless, articles still continue to appear in the literature claiming chromium is an essential element. Chromium has been marketed as an agent to reduce body mass and develop muscle; however, such marketing claims are no longer allowed in the United States because these claims, similar to claims of essential status, are not supported by experiments. Trivalent chromium has also been proposed as a therapeutic agent to increase insulin sensitivity and affect lipid metabolism. Although effective in certain rodent models, beneficial effects in humans have not been unequivocally established. Molecular mechanisms have been proposed for the beneficial effects but have not been definitively shown to occur in animals. © 2017 American Society for Nutrition.

Gracilaria widely known as a source of essential trace elements. However this red seaweeds also has great potential for being developed into commercial products. This study examined the sequential pattern of essential trace elements composition in fresh Gracilaria verrucosa and a selection of its generated products, nemely extracted agar, Gracilaria salt and Gracilaria residue. The sample was collected from a brackish water pond, located in north part Semarang, Central Java. The collected sample was then dried under the sun, and subsequently processed into aformentioned generated products. The Gracilaria salt was obtain by soaking the sun dried Gracilaria overnight in fresh water overnight. The resulted salt solution was then boiled leaving crystal salt. Extracted agar was obtained with alkali agar extraction method. The rest of remaining material was considered as Gracilaria residue. The entire process was repeated 3 times. The compositin of trace elements was examined using ICP-MS Spectrometry. Collected data was then analyzed by ANOVA single factor. Resulting sequential pattern of its essential trace elements composition was compared. A regular table salt was used as controls. Resuts from this study revealed that Gracilaria verrucosa and its all generated products all have similarly patterned the composition of essential trace elements, where Mn>Zn>Cu>Mo. Additionally this pattern is similar to different subspecies of Gracilaria from different location and and different season. However, Gracilaria salt has distinctly different pattern of sequential essential trace elements composition compared to table salt.

At present, great attention is paid to the origin of man-made micro elemental anomalies. To monitor the state of the environment and its effects on the human body, of great importance is the determination of the amount and distribution of various chemical elements in the dentin and enamel of the teeth. To determine the essential (Ca, Zn, Mn, Ni), conditionally essential (Rb, Ni, Sr) and toxic (Pb, Hg) trace elements in the mineralized tissues of the teeth and to identify the relationship between the elemental composition of the tooth structure and the state of the general and dental health depending on the state of the environment, we have examined 29 children aged 3-4 years who have carried out analysis of hard tissue of teeth (teeth used for remote medical reasons) for the maintenance of nine chemical elements. Children living in a relatively environmentally favorable conditions essential value and conditionally essential elements in the mineralized tissues of the teeth were within normal limits, and toxic elements slightly increased limits that differ from those of children living in environmentally disadvantaged areas. In particular, these essential elements were significantly reduced (except for zinc), as indicators of toxic elements - mercury and lead, increased by 12.5% and 44.5%, respectively, which is clearly reflected on the state of dental health because noted decompensated form of tooth decay. Thus, deviations in a state of general and dental health of children associated with an imbalance of macro-and microelements in the mineralized tissues of the teeth.

Reporting quality and risk of bias in randomised trials in health professions education.

Complete reporting of research is essential to enable consumers to accurately appraise, interpret and apply findings. Quality appraisal checklists are giving way to tools that judge the risk for bias. We sought to determine the prevalence of these complementary aspects of research reports (completeness of reporting and perceived risk for bias) of randomised studies in health professions education. We searched bibliographic databases for randomised studies of health professions education. We appraised two cohorts representing different time periods (2008-2010 and 2014, respectively) and worked in duplicate to apply the CONSORT guidelines and Cochrane Risk of Bias tool. We explored differences between time periods using independent-samples t-tests or the chi-squared test, as appropriate. We systematically identified 180 randomised studies (2008-2010, n = 150; 2014, n = 30). Frequencies of reporting of CONSORT elements within full-text reports were highly variable and most elements were reported in fewer than 50% of studies. We found a statistically significant difference in the CONSORT reporting index (maximum score: 500) between the 2008-2010 (mean ± standard deviation [SD]: 242.7 ± 55.6) and 2014 (mean ± SD: 311.6 ± 53.2) cohorts (p < 0.001). High or unclear risk for bias was most common for allocation concealment (157, 87%) and blinding of participants (147, 82%), personnel (152, 84%) and outcome assessors (112, 62%). Most risk for bias elements were judged to be unclear (range: 51-84%). Risk for bias elements significantly improved over time for blinding of participants (p = 0.007), incomplete data (p < 0.001) and the presence of other sources of bias (p < 0.001). Reports of randomised studies in health professions education frequently omit elements recommended by the CONSORT statement. Most reports were assessed as having a high or unclear risk for bias. Greater attention to how studies are reported at study outset and in manuscript preparation could improve levels of complete transparent reporting. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

The purpose of planned clinical experience for students of nursing is primarily to provide students with the opportunity to develop their clinical skills, integrate theory and practice, and assist with their socialization into nursing. Nursing, in the main, is a practice-based profession. To this extent, it is essential that nurse education continues to have a strong practical element despite its full integration into higher education institutions (Department of Health, 1999). However, providing adequate support and supervision for learners is challenging. Undoubtedly, exacerbated by increasing numbers of learners, staff shortages and mentors training deficits. This article aims to critically analyse several strategies, which can be used to promote clinical learning.

In the global nursing community, schools of nursing are increasingly developing initiatives and networks across national boundaries. This article describes the process undertaken at a school of nursing to determine its global health priorities and develop a program of global initiatives for nursing education. A series of meetings were held to determine faculty global activities and gauge interest in designing a 5-year strategic plan for the program. A volunteer Strategic Planning Work-group was convened to formalize a mission, vision, and strategic plan for the program, which were presented to, refined by, and vetted by an advisory board and the faculty at large. We recommend this process to schools committed to developing or expanding a program dedicated to global initiatives and a global perspective in educational planning. Involving stakeholders, building on current strengths, and aligning with mission and vision are essential elements for developing a meaningful program of global initiatives for nursing education.

The use of inductively coupled plasma mass spectrometry (ICP-MS) for the determination of toxic and essential elements in different types of food samples

NASA Astrophysics Data System (ADS)

Voica, C.; Dehelean, A.; Kovacs, M. H.

2012-02-01

Food is the primary source of essential elements for humans and it is an important source of exposure to toxic elements. In this context, levels of essential and toxic elements must be determined routinely in consumed food products. The content of trace elements (As, Pb, Cu, Cd, Zn, Sn, Hg) in different types of food samples (e.g. rice, bread, sugar, cheese, milk, butter, wheat, coffee, chocolate, biscuits pasta, etc.) was determined, using inductively coupled plasma mass spectrometry (ICP-MS). Trace element contents in some foods were higher than maximum permissible levels of toxic metals in human food (Cd in bread, Zn in cheese, Cu in coffee, Hg in carrots and peppers).

Cognitive Load Theory: implications for medical education: AMEE Guide No. 86.

PubMed

Young, John Q; Van Merrienboer, Jeroen; Durning, Steve; Ten Cate, Olle

2014-05-01

Cognitive Load Theory (CLT) builds upon established models of human memory that include the subsystems of sensory, working and long-term memory. Working memory (WM) can only process a limited number of information elements at any given time. This constraint creates a "bottleneck" for learning. CLT identifies three types of cognitive load that impact WM: intrinsic load (associated with performing essential aspects of the task), extraneous load (associated with non-essential aspects of the task) and germane load (associated with the deliberate use of cognitive strategies that facilitate learning). When the cognitive load associated with a task exceeds the learner's WM capacity, performance and learning is impaired. To facilitate learning, CLT researchers have developed instructional techniques that decrease extraneous load (e.g. worked examples), titrate intrinsic load to the developmental stage of the learner (e.g. simplify task without decontextualizing) and ensure that unused WM capacity is dedicated to germane load, i.e. cognitive learning strategies. A number of instructional techniques have been empirically tested. As learners' progress, curricula must also attend to the expertise-reversal effect. Instructional techniques that facilitate learning among early learners may not help and may even interfere with learning among more advanced learners. CLT has particular relevance to medical education because many of the professional activities to be learned require the simultaneous integration of multiple and varied sets of knowledge, skills and behaviors at a specific time and place. These activities possess high "element interactivity" and therefore impose a cognitive load that may surpass the WM capacity of the learner. Applications to various medical education settings (classroom, workplace and self-directed learning) are explored.

The missing foundation in teacher education: Knowledge of the structure of spoken and written language.

PubMed

Moats, L C

1994-01-01

Reading research supports the necessity for directly teaching concepts about linguistic structure to beginning readers and to students with reading and spelling difficulties. In this study, experienced teachers of reading, language arts, and special education were tested to determine if they have the requisite awareness of language elements (e.g., phonemes, morphemes) and of how these elements are represented in writing (e.g., knowledge of sound-symbol correspondences). The results were surprisingly poor, indicating that even motivated and experienced teachers typically understand too little about spoken and written language structure to be able to provide sufficient instruction in these areas. The utility of language structure knowledge for instructional planning, for assessment of student progress, and for remediation of literacy problems is discussed.The teachers participating in the study subsequently took a course focusing on phonemic awareness training, spoken-written language relationships, and careful analysis of spelling and reading behavior in children. At the end of the course, the teachers judged this information to be essential for teaching and advised that it become a prerequisite for certification. Recommendations for requirements and content of teacher education programs are presented.

Evidence-based health promotion programmes, including HIV/AIDS prevention and sexuality education programmes, are often transferred to other cultures, priority groups and implementation settings. Challenges in this process include the identification of retaining core elements that relate to the programme's effectiveness while making changes that enhances acceptance in the new context and for the new priority group. This paper describes the use of a systematic approach to programme adaptation using a case study as an example. Intervention Mapping, a protocol for the development of evidence-based behaviour change interventions, was used to adapt the comprehensive school-based sexuality education programme 'The World Starts With Me'. The programme was developed for a priority population in Uganda and adapted to a programme for Indonesian secondary school students. The approach helped to systematically address the complexity and challenges of programme adaptation and to find a balance between preservation of essential programme elements (i.e. logic models) that may be crucial to the programme's effectiveness, including key objectives and theoretical behaviour change methods, and the adaptation of the programme to be acceptable to the new priority group and the programme implementers.

2015-01-01

The levels of seven essential trace elements (Mn, Co, Ni, Cu, Zn, Se, and Mo) and six non-essential trace elements (Cr, As, Cd, Sb, Hg, and Pb) in a total of 89 drinking water samples collected in Shenzhen, China were determined using inductively coupled plasma mass spectrometry (ICP-MS) in the present study. Both the essential and non-essential trace elements were frequently detectable in the different kinds of drinking waters assessed. Remarkable temporal and spatial variations were observed among most of the trace elements in the tap water collected from two tap water treatment plants. Meanwhile, potential human health risk from these non-essential trace elements in the drinking water for local residents was also assessed. The median values of cancer risks associated with exposure to carcinogenic metals via drinking water consumption were estimated to be 6.1 × 10(-7), 2.1 × 10(-8), and 2.5 × 10(-7) for As, Cd, and Cr, respectively; the median values of incremental lifetime for non-cancer risks were estimated to be 6.1 × 10(-6), 4.4 × 10(-5), and 2.2 × 10(-5) for Hg, Pb, and Sb, respectively. The median value of total incremental lifetime health risk induced by the six non-essential trace elements for the population was 3.5 × 10(-5), indicating that the potential health risks from non-carcinogenic trace elements in drinking water also require some attention. Sensitivity analysis indicates that the most important factor for health risk assessment should be the levels of heavy metal in drinking water.

The objective of this study was to investigate the content of essential elements in medicinal plants in the Kingdom of Saudi Arabia (KSA). Five different medical plants (mahareeb (Cymbopogon schoenanthus), sheeh (Artemisia vulgaris), harjal (Cynanchum argel delile), nabipoot (Equisetum arvense), and cafmariam (Vitex agnus-castus)) were collected from Madina city in the KSA. Five elements Fe, Mn, Zn, Cu, and Se were determined by using inductively coupled plasma mass spectrometry (ICP-MS). Fe levels were the highest and Se levels were the lowest in all plants. The range levels of all elements in all plants were as follows: Fe 193.4–1757.9, Mn 23.6–143.7, Zn 15.4–32.7, Se 0.13–0.92, and Cu 11.3–21.8 µg/g. Intakes of essential elements from the medical plants in infusion were calculated: Fe 4.6–13.4, Mn 6.7–123.2, Zn 7.0–42.7, Se 0.14–1.5, and Cu 1.5–5.0 µg/dose. The calculated intakes of essential elements for all plants did not exceed the daily intake set by the World Health Organization (WHO) and European Food Safety Authority (EFSA). These medicinal plants may be useful sources of essential elements, which are vital for health. PMID:29744234

Informative titles and abstracts facilitate reading and searching the literature. To evaluate the quality of titles and abstracts of full-length reports of experimental studies in medical education. We used a random sample of 110 articles (of 185 eligible articles) describing education experiments. Articles were published in 2003 and 2004 in Academic Medicine, Advances in Health Sciences Education, American Journal of Surgery, Journal of General Internal Medicine, Medical Education and Teaching and Learning in Medicine. Titles were categorised as informative, indicative, neither, or both. Abstracts were evaluated for the presence of a rationale, objective, descriptions of study design, setting, participants, study intervention and comparison group, main outcomes, results and conclusions. Of the 105 articles suitable for review, 86 (82%) had an indicative title and 10 (10%) had a title that was both indicative and informative. A rationale was present in 66 abstracts (63%), objectives were present in 84 (80%), descriptions of study design in 20 (19%), setting in 29 (28%), and number and stage of training of participants in 42 (40%). The study intervention was defined in 55 (52%) abstracts. Among the 48 studies with a control or comparison group, this group was defined in 21 abstracts (44%). Study outcomes were defined in 64 abstracts (61%). Data were presented in 48 (46%) abstracts. Conclusions were presented in 97 abstracts (92%). Reports of experimental studies in medical education frequently lack the essential elements of informative titles and abstracts. More informative reporting is needed.

Harlequin-Inspired Story-Based Learning: An Educational Innovation for Pediatric Nursing Communication.

PubMed

Shaw, Alison; Lind, Candace; Ewashen, Carol

2017-05-01

Effective communication with patients and families is essential for quality care in the pediatric environment. Despite this, the current structure and content of undergraduate nursing education often contributes to novice RNs feeling unprepared to manage complex pediatric communication situations. By merging the characteristics of the Harlequin persona with the structure of story-based learning, undergraduate students can be introduced to increasingly advanced pediatric communication scenarios in the classroom. Although story-based learning encourages students to identify and address the contextual and emotional elements of a story, the Harlequin encourages educators to challenge assumptions and upset the status quo. Nursing students can develop advanced communication abilities and learn to identify and cope with the emotions and complexities inherent in pediatric practice and communication. Harlequin-inspired story-based learning can enable nurse educators to create interesting, realistic, and challenging pediatric nursing stories designed to push students outside their comfort zones and enhance their advanced pediatric communication abilities.

Simulation-based education has made its entry into surgical residency training, particularly as an adjunct to hands-on clinical experience. However, one of the ongoing challenges to wide adoption is the capacity of simulators to incorporate educational features required for effective learning. The aim of this study was to identify strengths and limitations of spine simulators to characterize design elements that are essential in enhancing resident education. We performed a mixed qualitative and quantitative cohort study with a focused survey and interviews of stakeholders in spine surgery pertaining to their experiences on 3 spine simulators. Ten participants were recruited spanning all levels of training and expertise until qualitative analysis reached saturation of themes. Participants were asked to perform lumbar pedicle screw insertion on 3 simulators. Afterward, a 10-item survey was administrated and a focused interview was conducted to explore topics pertaining to the design features of the simulators. Overall impressions of the simulators were positive with regards to their educational benefit, but our qualitative analysis revealed differing strengths and limitations. Main design strengths of the computer-based simulators were incorporation of procedural guidance and provision of performance feedback. The synthetic model excelled in achieving more realistic haptic feedback and incorporating use of actual surgical tools. Stakeholders from trainees to experts acknowledge the growing role of simulation-based education in spine surgery. However, different simulation modalities have varying design elements that augment learning in distinct ways. Characterization of these design characteristics will allow for standardization of simulation curricula in spinal surgery, optimizing educational benefit. Copyright © 2017 Elsevier Inc.

Long, Debbie A; Young, Jeanine; Rickard, Claire M; Mitchell, Marion L

2013-04-01

One strategy to address the current nursing shortage in specialty areas has been to introduce graduate nurse programs. However introducing novice nurses to specialty areas raises concerns around education and competency which, in turn, highlights the need to identify and prioritise the elements of competent paediatric intensive care unit (PICU) nursing care considered essential to safe practice. To determine the key knowledge, skills and attributes of competent level PICU nurses. A practice analysis survey of 15 nurse educators was conducted in all eight Australian and New Zealand PICUs during 2008. Three areas of practice essential to PICU nursing competence were explored: patients most commonly cared for; frequency and criticality of activities performed; and level of independence against critical care nursing competency standards. Data were analysed using descriptive statistics. Cardiac and respiratory problems accounted for over 50% of patients cared for by competent level nurses. Cardiac and respiratory activities were therefore also ranked as the most important activities. Respondents identified that competency domains of teamwork and professional practice are performed with minimal supervision, whereas clinical problem solving requires supervision and assistance. PICU nurses are performing activities and caring for a breadth of complex patients within a year of entering the workforce. Using a practice analysis to define actual practice and expectations can assist in the identification and prioritisation of content for graduate and other educational programs.

2017-08-01

Poster presentations are increasingly popular for dissemination of scientific and clinical knowledge at professional meetings; however, this professional skill is generally absent from advanced practice registered nurse (APRN) curricula and acquisition of the skill must occur in other arenas. The purpose of this article is to promote professional development by educating APRNs, students, and faculty on the essentials of poster development and presentation. To aid in poster presentation skill development, types of posters, advantages and disadvantages, content and design, and tips to enhance these presentations are discussed. What is known on these topics is summarized and emphasis on professional appearance and conduct is highlighted. Content and layout, use of color, imagery, and positive and negative space are crucial design elements. Poster presentation essentials include being prepared, professional appearance, and professional behavior. Designing and presenting a professional poster is an essential skill for all APRNs as the ability to communicate knowledge is central to the role. ©2017 American Association of Nurse Practitioners.

Interpersonal skill in medicine: the essential partner of verbal communication.

Dyche, Lawrence

2007-07-01

Medical educators have promoted skillful communication as a means for doctors to develop positive relationships with their patients. In practice, communication tends to be defined primarily as what doctors say, with less attention to how, when, and to whom they say it. These latter elements of communication, which often carry the emotional content of the discourse, are usually referred to as interpersonal skills. Although recognized as important by some educators, interpersonal skills have received much less attention than task-oriented, verbal aspects. Moreover, the field lacks a common language and conceptualization for discussing them. This paper offers a framework for describing interpersonal skills and understanding their relationship to verbal communication and describes an interpersonal skill-set comprised of Understanding, Empathy, and Relational Versatility.

A comprehensive discharge plan for a patient with a new stoma is needed to ensure the individual receives the necessary ostomy education prior to discharge. The plan should include teaching basic skills and providing information about how to manage the ostomy (ie, emptying and changing the pouch, how to order supplies, available manufacturers, dietary/fluid guidelines, potential complications, medications, and managing gas and odor), assisting with transitions in care, and providing information about resources for support and assistance. The purpose of this best practice guideline is to provide clinicians with a brief overview of the essential elements that should be included in the discharge plan to facilitate patient education and the transition of care from hospital to home.

Objectives. We evaluated efforts in New York to build a consensus between community health workers (CHWs) and employers on CHWs’ scope of practice, training standards, and certification procedures. Methods. We conducted multiple-choice surveys in 2008 and 2010 with 226 CHWs and 44 employers. We compared CHWs’ and employers’ recommendations regarding 28 scope of practice elements. The participatory ranking method was used to identify consensus scope of practice recommendations. Results. There was consensus on 5 scope of practice elements: outreach and community organizing, case management and care coordination, home visits, health education and coaching, and system navigation. For each element, 3 to 4 essential skills were identified, giving a total of 27 skills. These included all skills recommended in national CHW studies, along with 3 unique to New York: computer skills, participatory research methods, and time management. Conclusions. CHWs and employers in New York were in consensus on CHWs’ scope of practice on virtually all of the detailed core competency skills. The CHW scope of practice recommendations of these groups can help other states refine their scope of practice elements. PMID:22897548

Nutritional Aspects of Essential Trace Elements in Oral Health and Disease: An Extensive Review

PubMed Central

Hussain, Mohsina

2016-01-01

Human body requires certain essential elements in small quantities and their absence or excess may result in severe malfunctioning of the body and even death in extreme cases because these essential trace elements directly influence the metabolic and physiologic processes of the organism. Rapid urbanization and economic development have resulted in drastic changes in diets with developing preference towards refined diet and nutritionally deprived junk food. Poor nutrition can lead to reduced immunity, augmented vulnerability to various oral and systemic diseases, impaired physical and mental growth, and reduced efficiency. Diet and nutrition affect oral health in a variety of ways with influence on craniofacial development and growth and maintenance of dental and oral soft tissues. Oral potentially malignant disorders (OPMD) are treated with antioxidants containing essential trace elements like selenium but even increased dietary intake of trace elements like copper could lead to oral submucous fibrosis. The deficiency or excess of other trace elements like iodine, iron, zinc, and so forth has a profound effect on the body and such conditions are often diagnosed through their early oral manifestations. This review appraises the biological functions of significant trace elements and their role in preservation of oral health and progression of various oral diseases. PMID:27433374

On an algorithmic definition for the components of the minimal cell.

Martínez, Octavio; Reyes-Valdés, M Humberto

2018-01-01

Living cells are highly complex systems comprising a multitude of elements that are engaged in the many convoluted processes observed during the cell cycle. However, not all elements and processes are essential for cell survival and reproduction under steady-state environmental conditions. To distinguish between essential from expendable cell components and thus define the 'minimal cell' and the corresponding 'minimal genome', we postulate that the synthesis of all cell elements can be represented as a finite set of binary operators, and within this framework we show that cell elements that depend on their previous existence to be synthesized are those that are essential for cell survival. An algorithm to distinguish essential cell elements is presented and demonstrated within an interactome. Data and functions implementing the algorithm are given as supporting information. We expect that this algorithmic approach will lead to the determination of the complete interactome of the minimal cell, which could then be experimentally validated. The assumptions behind this hypothesis as well as its consequences for experimental and theoretical biology are discussed.

2018-03-01

Children's media have the capacity to prepare young learners to develop the knowledge, attitudes, and skills they need to contribute to a more peaceful world. Research suggests international coproductions of Sesame Street and other children's media efforts are linked to positive impact on how viewers perceive themselves and their own cultures, as well as how they perceive others. Creating such media, however, relies on a commitment to a complex development process where the educational needs of children are considered alongside intra- and intergroup dynamics and political realities. This paper presents a practitioners' perspective on the essential components of children's media programs for peacebuilding and, in so doing, recommends a way forward for producing children's media in this domain. © 2018 Wiley Periodicals, Inc.

Element profiling is an interesting approach for understanding neurodegenerative processes, considering that compelling evidences show that element toxicity might play a crucial role in the onset and progression of Alzheimer’s disease (AD). Aim of this study was to profile 22 serum elements in subjects with or at risk of AD. Thirtyfour patients with probable AD, 20 with mild cognitive impairment (MCI), 24 with subjective memory complaint (SMC) and 40 healthy subjects (HS) were included in the study. Manganese, iron, copper, zinc, selenium, thallium, antimony, mercury, vanadium and molybdenum changed significantly among the 4 groups. Several essential elements, such as manganese, selenium, zinc and iron tended to increase in SMC and then progressively to decrease in MCI and AD. Toxic elements show a variable behavior, since some elements tended to increase, while others tended to decrease in AD. A multivariate model, built using a panel of six essential elements (manganese, iron, copper, zinc, selenium and calcium) and their ratios, discriminated AD patients from HS with over 90% accuracy. These findings suggest that essential and toxic elements contribute to generate a distinctive signature during the progression of AD, and their monitoring in elderly might help to detect preclinical stages of AD.

Trace elements in certain amounts are essential for childrens' health, because they are present in tissues participating in metabolic reactions of organisms. Deficiency of the essential elements may result in malnutrition, impaired body immunity, and poor resistance to disease. These conditions might be enhanced against a background of additional adverse environmental factors such as toxic elements. The analysis of elements in childrens' hair will give information on the deficiency of essential elements and excess of toxic elements in relation to their diet. In this study, 141 hair samples from children (girls and boys) living in two regions of Tanzanian mainland (Dar es Salaam and Moshi) and the island of Zanzibar have been analysed for trace elements in relation to food consumption habits. The analysis was carried out using long and short irradiation instrumental neutron activation analysis (INAA) of the Nuclear Physics Institute at Rez, Czech Republic. Arithmetic and geometric means with their respective standard deviations are presented for 19 elements. Subgroups were formed according to age, gender, and geographic regions from which the samples were collected. Differences in concentrations for the groups and with other childhood populations were explored and discussed.

We do not know all the essential elements with certainty and we know even less about the functions of apparently non-essential elements. In this article, I discuss a basis for a biological periodic system of the elements and that biochemistry should include the elements that are traditionally part of inorganic chemistry and not only those that are in the purview of organic chemistry. A biological periodic system of the elements needs to specify what “essential” means and to which biological species it refers. It represents a snapshot of our present knowledge and is expected to undergo further modifications in the future. An integrated approach of biometal sciences called metallomics is required to understand the interactions of metal ions, the biological functions that their chemical structures acquire in the biological system, and how their usage is fine-tuned in biological species and in populations of species with genetic variations (the variome).

Mineral and essential trace elements are involved in numerous physiological processes in mammals. Often, diseases are associated with an imbalance of the electrolyte homeostasis. In this study, the concentrations of mineral elements (P, S, K, Ca) and essential trace elements (Fe, Cu, Zn, Se, Rb, Sr) in whole blood of harbor seals ( Phoca vitulina) were determined using total-reflection X-ray fluorescence spectrometry (TXRF). Samples from 81 free-ranging harbor seals from the North Sea and two captive seals were collected during 2003-2005. Reference ranges and element correlations for health status determination were derived for P, S, K, Ca, Fe, Cu, and Zn level in whole blood. Grouping the seals by age, gender and sample location the concentration levels of the elements were compared. The blood from two captive seals with signs of diseases and four free-ranging seals showed reduced element levels of P, S, and Ca and differences in element correlation of electrolytes were ascertained. Thus, simultaneous measurements of several elements in only 500 μL volumes of whole blood provide the possibility to obtain information on both, the electrolyte balance and the hydration status of the seals. The method could therefore serve as an additional biomonitoring tool for the health assessment.

Essential elements (K, Ca, P, S, Cl, Mn, Fe, Cu, Zn, Ni, Br, and I) and nonessential or toxic elements (Al, Ti, Si, Rb, Sr, As, Cd, Sn, and Pb) were determined by energy-dispersive polarized x-ray fluorescence spectrometry in 14 seaweeds purchased in local specialty stores in Italy and consumed by humans. The differences in elements between the algae species reached up to 2-4 orders of magnitude. Lithothamnium calcareum showed the highest levels of Ca, Al, Si, Fe, and Ti. Palmaria palmata showed the highest concentrations of K, Rb, and Cl. The highest content of S was in Chondrus crispus. Laminaria digitata contained the highest concentrations of total As, Cd, Sn, Br, and I. The highest concentration of Zn was in Chlorella pyrenoidosa. Ulva lactuca displayed the highest levels of Cu, Ni, Mn, and Pb. Iodine levels ranged from 3.4 in Chlorella pyrenoidosa to 7316 mg/kg(dry) in Laminaria digitata. The nutrimental importance of essential elements was assessed using nutritional requirements. The results showed that the consumption of algae might serve as an important source of the essential elements. Health risk due to the toxic elements present in seaweed was estimated using risk estimators. Total As, Cd, and Pb concentrations ranged from <1 to 67.6, to 7.2 and to 6.7 mg/kg(dry) respectively; therefore, their contribution to total elemental intake does not appear to pose any threat to the consumers, but the concentrations of these elements should be controlled to protect the consumer against potential adverse health risks.

Manpower planning for oral health.

The challenges to the dental profession include the unemployed dentists, the radical changes to the numbers of dental schools and their intake of new students; and the imbalance which exists on a global scale between oral health personnel and service need and demand. Workforce planning needs clearly defined goals which relate to the nature of disease, the shift from treatment to prevention and consumer expectations. A wide variety of information is required to facilitate communication and co-operation with elements of the political system, the educational system, professional bodies, health service agencies and consumers. It is essential that national planning and monitoring groups be established with membership from dental associations, educational institutions and government. In workforce planning there must be the ability to accept change, to be creative, to be positive, and to be decisive.

A series of court cases litigated by the National Association for the Advancement of Colored People Legal Defense and Education Fund between 1956 and 1967 laid the foundation for elimination of overt discrimination in hospitals and professional associations. The landmark case, Simkins v Moses H. Cone Memorial Hospital (1963), challenged the use of public funds to expand segregated hospital care. The second case, Cypress v Newport News Hospital Association (1967), reaffirmed the federal government’s application of Medicare certification guidelines to force hospitals to open up patient admissions, education programs, and staff privileges to all citizens and physicians. Pursuit of a legal strategy against racist policies was an essential element in a national campaign to eliminate discrimination in health care delivery in the United States. PMID:15117685

Rowthorn, Virginia

2015-01-01

There has been dramatic growth in the number of innovative university programs that focus on social justice and teach community-based strategies that are applicable both domestically in North America and internationally. These programs often are referred to as global/local and reflect an effort to link global health and campus community engagement efforts to acknowledge that a common set of transferable skills can be adapted to work with vulnerable populations wherever they may be. However, the concepts underlying global/local education are undertheorized and universities struggle to make the global/local link without a conceptual framework to guide them in this pursuit. This study reports on the outcomes of a 2015 national meeting of 120 global health educators convened to discuss the concepts underlying global/local education, to share models of global/local programs, and to draft a preliminary list of critical elements of a meaningful and didactically sound global/local educational program. A qualitative analysis was conducted of the discussions that took place at the national meeting. The analysis was supported by videorecordings made of full-group discussions. Results were categorized into a preliminary list of global/local program elements. Additionally, a synthesis was developed of critical issues raised at the meeting that warrant future discussion and study. A preliminary list was developed of 7 program components that global health educators consider essential to categorize a program as global/local and to ensure that such a program includes specific critical elements. Interest is great among global health educators to understand and teach the conceptual link between learning on both the global and community levels. Emphasis on this link has high potential to unite the siloed fields of global health and domestic community public health and the institutions, funding options, and career pathways that flow from them. Future research should focus on implementation of global/local programming and evaluation of student learning and community health outcomes related to such programs. Copyright © 2015 The Author.

Cardiopulmonary resuscitation training is an essential element of clinical skill development for healthcare providers. The International Liaison Committee on Resuscitation has described issues related to cardiopulmonary resuscitation and emergency cardiovascular care education. Educational interventions have been initiated to try to address these issues using a team-based approach and simulation technologies that offer a controlled, safe learning environment. The aim of the study is to review and synthesize published studies that address the primary question "What are the features and effectiveness of educational interventions related to simulation-enhanced, team-based cardiopulmonary resuscitation training?" We conducted a systematic review focused on educational interventions pertaining to cardiac arrest and emergencies that addressed this main question. The findings are presented together with a discussion of the effectiveness of various educational interventions. In conclusion, student attitudes toward interprofessional learning and simulation experiences were more positive. Research reports emphasized the importance of adherence to established guidelines, adopting a holistic approach to training, and that preliminary training, briefing, deliberate practices, and debriefing should help to overcome deficiencies in cardiopulmonary resuscitation training.

To determine the daily intake of essential micronutrients and toxic elements through breast milk in exclusive and nonexclusive breastfed infants living in an area with major mine tailing deposition (n = 24), compared with a control area (n = 11). The milk volume ingested by 2 to 4 and 4 to 6 month infants was measured by a stable isotopic method. Elements in milk, maternal and infant urine, and drinking water were measured by inductively coupled plasma mass spectrometry (ICP-MS). Similar breast milk volume and essential micronutrients intake in groups of exclusively breastfed infants, but more cadmium, boron, and lithium through breastfeeding in experimental area was found. This exposure was even higher in the nonexclusively breastfed infants, who also ingested more arsenic, boron, and lithium than exclusive breastfed infants. The use of the deuterium and the ICP-MS methods made it possible to evaluate the exact amount of essential and toxic elements ingested by infants through breast milk demonstrating that lower amount of toxic elements are transferred to exclusive breastfed infants compared with those who additionally received nonmaternal milk.

Evidente, V G

2000-10-01

Tics are characterized by sterotyped, purposeless, and irregularly repetitive movements and usually can be classified as chronic motor or vocal tic disorders, transient tic disorders, or Tourette's syndrome. The latter is a complex disorder associated with multiple tics and often accompanied by other conditions, such as ADHD and obsessive-compulsive disorder. Treatment can be difficult, and drug therapy should begin with agents least likely to cause problems for the patient. Education of the patient and family and support from the physician and other care providers are essential elements of effective management.

There is increasing evidence linking levels of trace elements (TEs) in adipose tissue with certain chronic conditions (e.g., diabetes or obesity). The objectives of this study were to assess concentrations of a selection of nine essential and possibly-essential TEs in adipose tissue samples from an adult cohort and to explore their socio-demographic, dietary, and lifestyle determinants. Adipose tissue samples were intraoperatively collected from 226 volunteers recruited in two public hospitals from Granada province. Trace elements (Co, Cr, Cu, Fe, Mn, Mo, Se, V, and Zn) were analyzed in adipose tissue by high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Data were collected on socio-demographic characteristics, lifestyle, diet, and health status by face-to-face interview. Predictors of TE concentrations were assessed by using multivariable linear and logistic regression. All TEs were detected in all samples with the exception of Se (53.50%). Iron, zinc, and copper showed the highest concentrations (42.60 mg/kg, 9.80 mg/kg, and 0.68 mg/kg, respectively). Diet was the main predictor of Cr, Fe, Mo, and Se concentrations. Body mass index was negatively associated with all TEs (β coefficients = -0.018 to -0.593, p = 0.001-0.090) except for Mn and V. Age showed a borderline-significant positive correlation with Cu (β = 0.004, p = 0.089). Residence in a rural or semi-rural area was associated with increased Co, Cr, Fe, Mo, Mn, V and Zn concentrations and with β coefficients ranging from 0.196 to 0.544 (p < 0.05). Furthermore, individuals with higher educational level showed increased Cr, Co, Fe and V concentrations (β coefficients = 0.276-0.368, p = 0.022-0.071). This is the first report on the distribution of these TEs in adipose tissue and on their determinants in a human cohort and might serve as an initial step in the elucidation of their clinical relevance.

2002-12-01

To develop a framework to support the institutionalization of quality assurance (QA). The framework for institutionalizing QA consists of a model of eight essential elements and a 'roadmap' for the process of institutionalization. The essential elements are the building blocks required for implementing and sustaining QA activities. Core QA activities include defining, measuring and improving quality. The essential elements are grouped under three categories: the internal enabling environment (internal to the organization or system), organizing for quality, and support functions. The enabling environment contains the essential elements of leadership, policy, core values, and resources. Organizing for quality includes the structure for implementing QA. Three essential elements are primarily support functions: capacity building, communication and information, and rewarding quality. The model can be applied at the level of an organization or a system. The paper also describes the process of institutionalizing QA, starting from a state of preawareness, passing through four phases (awareness, experiential, expansion, and consolidation), and culminating in a state of maturity. The process is not linear; an organization may regress, vacillate between phases, or even remain stagnant. Some phases (e.g. awareness and experiential) may occur simultaneously. The framework has been introduced in nearly a dozen countries in Latin America and Africa. The conceptual model has been used to support strategic planning and directing Ministry of Health work plans, and also as a resource for determining the elements necessary to strengthen and sustain QA. The next step will be the development and evaluation of an assessment tool to monitor developmental progress in the institutionalization of QA.

Feedback: an essential element of student learning in clinical practice.

PubMed

Clynes, Mary P; Raftery, Sara E C

2008-11-01

Clinical practice is an essential component of the nursing curriculum. In order for the student to benefit fully from the experience regular performance feedback is required. Feedback should provide the student with information on current practice and offer practical advice for improved performance. The importance of feedback is widely acknowledged however it appears that there is inconsistency in its provision to students. The benefits of feedback include increased student confidence, motivation and self-esteem as well as improved clinical practice. Benefits such as enhanced interpersonal skills and a sense of personal satisfaction also accrue to the supervisor. Barriers to the feedback process are identified as inadequate supervisor training and education, unfavourable ward learning environment and insufficient time spent with students. In addition to the appropriate preparation of the supervisor effective feedback includes an appreciation of the steps of the feedback process, an understanding of the student response to feedback and effective communication skills.

A conceptual framework for international service-learning course planning: promoting a foundation for ethical practice in the physical therapy and occupational therapy professions.

2011-01-01

As physical therapy (PT) and occupational therapy (OT) educational programs endeavor to foster core values of social responsibility, justice, and altruism in an increasingly global community, the incorporation of local and international service-learning (ISL) into the curriculum is growing. Much of the research has focused on the measurement of student learning, with little written about the impact on the host community. Proponents of global health initiatives are calling for consideration of all stakeholders to ensure ethical practice. This paper explores the current literature related to PT and OT ISL and builds a conceptual framework for ISL course planning. The essential phases in the framework include: 1) pre-experience planning/preparation stage, 2) field immersion experience stage, and 3) postexperience stage. The essential elements are: 1) cultural competency training, 2) communication and coordination with community, 3) comprehensive assessment, and 4) strategic planning. The authors suggest this framework as a practical tool to structure ISL courses with an explicit emphasis on ethical concerns. Additionally, they seek to foster more dialogue and action related to the promotion of ethical practices in ISL in PT and OT education programs.

Integrating the quality and safety mission of teaching hospitals and graduate medical education (GME) is a necessary step to provide the next generation of physicians with the knowledge, skills, and attitudes they need to participate in health system improvement. Although many teaching hospital and health system leaders have made substantial efforts to improve the quality of patient care, few have fully included residents and fellows, who deliver a large portion of that care, in their efforts. Despite expectations related to the engagement of these trainees in health care quality improvement and patient safety outlined by the Accreditation Council for Graduate Medical Education in the Clinical Learning Environment Review program, a structure for approaching this integration has not been described.In this article, the authors present a framework that they hope will assist teaching hospitals in integrating residents and fellows into their quality and safety efforts and in fostering a positive clinical learning environment for education and patient care. The authors define the six essential elements of this framework-organizational culture, teaching hospital-GME alignment, infrastructure, curricular resources, faculty development, and interprofessional collaboration. They then describe the organizational characteristics required for each element and offer concrete strategies to achieve integration. This framework is meant to be a starting point for the development of robust national models of infrastructure, alignment, and collaboration between GME and health care quality and safety leaders at teaching hospitals.

The aim of the study was to review the Occupational Safety and Health Administration's (OSHA) 2012 to 2013 heat enforcement cases, using identified essential elements of heat illness prevention to evaluate employers' programs and make recommendations to better protect workers from heat illness. (1) Identify essential elements of heat illness prevention; (2) develop data collection tool; and (3) analyze OSHA 2012 to 2013 heat enforcement cases. OSHA's database contains 84 heat enforcement cases in 2012 to 2013. Employer heat illness prevention programs were lacking in essential elements such as providing water and shade; adjusting the work/rest proportion to allow for workload and effective temperature; and acclimatizing and training workers. In this set of investigations, most employers failed to implement common elements of illness prevention programs. Over 80% clearly did not rely on national standard approaches to heat illness prevention.

Over the 21st century, climate scientists expect Earth's temperature to continue increasing, very likely more than it did during the 20th century. Two anticipated results are rising global sea level and increasing frequency and intensity of heat waves, droughts, and floods. [IPCC 2007, USGCRP 2009] These changes will affect almost every aspect of human society, including economic prosperity, human and environmental health, and national security. Climate change will bring economic and environmental challenges as well as opportunities, and citizens who have an understanding of climate science will be better prepared to respond to both. Society needs citizens who understand the climate system and know how to apply that knowledge in their careers and in their engagement as active members of their communities. Climate change will continue to be a significant element of public discourse. Understanding the essential principles of climate science will enable all people to assess news stories and contribute to their everyday conversations as informed citizens. Key to our nations response to climate change will be a Climate Literate society that understands their influence on climate and climate’s influence on them and society. In order to ensure the nation increases its literacy, the Climate Literacy: Essential Principles of Climate Science document has been endorsed by the 13 Federal agencies that make up the US Global Change Research Program (http://globalchange.gov/resources/educators/climate-literacy) and twenty-four other science and educational institutions. This session will explore the coordinated efforts by the federal agencies and partner organizations to ensure a climate literate society.

In 2000, 63 (polished) white rice samples were collected in eight administrative areas all over South Korea and analyzed for 16 elements by inductively coupled plasma atomic emission spectrometry (ICP-AES). Potassium had the highest content, next to Mg, Ca, Si, Zn, Na, Al and Fe. Most of the samples contained worldwide average concentrations of essential and trace elements in rice grains reported by various researches. For inter-area differences in those elements in the rice, the statistical analysis showed no significant differences (p > 0.05) among the eight administrative areas, suggesting that inter-area differences were not substantial in most cases. Thus, the present data can be used as national background levels of elements in rice produced in South Korea. Using the published data on daily consumption of rice in South Korea, it was possible to estimate the daily intake of As, Cd, Cu, Pb and Zn via rice. The results showed that a regular consumption of rice produced in Korea plays an important role in accumulation of essential and trace elements in Korean, especially for farm-households consuming relatively large amounts of rice.

Many United States, school children perceive science, technology, engineering, and mathematics (STEM) as difficult, boring and often irrelevant subjects. The possible reasons for this problem are endlessly debated. However, the economic, social, and overall national importance of producing graduates who are technically literate and enthusiastic in their support of a rational scientific world is essential to our nation. This apparent STEM crisis should motivate the many scientific and engineering societies to develop STEM outreach programs aimed at students, parents, teachers and schools (grades K-12). The American Institute of Aeronautics and Astronautics (AIAA) is among those organizations that have identified the need to educate students and teachers about STEM current events and their direct effects on the United States population in a way that motivates both. The AIAA has established a pre-college outreach program that has several major elements that will be described in this paper. Elements focused on the teachers include a pre-college Educator Associate Membership program, classroom grants to support hands-on learning activities, Educator of the Year awards and recognition program and two national workshop events. The first workshop event, Passport to the Future, is held annually in conjunction with the Joint Propulsion Conference. It is intended to provide summertime training in Aerospace science education to classroom teachers, in conjunction with a national professional conference. The second workshop, Education Alley, is held in the fall in conjunction with the “Space” series of conferences. This program is aimed at direct outreach to local students in the conference host city, providing fun, interesting, and educational events that promote STEM. The AIAA also encourages and supports pre-college outreach activities sponsored by the local AIAA sections through leadership training, activity and material support.

In this study, 88 randomly selected samples of butter produced in the Black Sea region of Turkey were purchased from different retail markets during different periods and investigated for toxic and essential elements content. Quantitative analyses of elements in the samples were performed using an inductively coupled plasma-mass spectroscopy (ICP-MS). Mean concentrations of As, Cr, Cu, Fe, Mn, Ni, Pb, Se and Zn in the butter samples were 18.93, 100.32, 384.66, 4199.1, 887.47, 168.64, 56.13, 16.34 and 384.66 µg kg(-1), respectively. Cd and Co were detected in 19 (mean content 0.29 µg kg(-1)) and 81 (mean content 3.81 µg kg(-1)) samples of 88 butter samples, respectively. However, the dietary intake of these elements by the population of the Black Sea region is currently well below the dietary reference intake (DRI) and provisional tolerable weekly intake (PTWI) levels of essential and toxic elements.

The metal contents of eleven black tea samples, four cultivated in Iran and seven imported, and their tea infusions were determined. Twelve elements consisting toxic metals (Al, As, Pb, Cr, Cd, and Ni) and essential mineral elements (Fe, Zn, Cu, Mn, Ca, and Mg) were analyzed using inductively coupled plasma atomic emission spectroscopy (ICP-AES). Al, Ca, Mg, and Mn ranged in black tea leaves at mg g(-1) levels, while Cr, Fe, Ni, Cu, Zn were at microg g(-1) levels. Analysis of variance showed no statistically significant differences among most elements determined in cultivated and imported black teas in Iran except for Ni and Cu. The extraction efficiency of each element into tea infusions was evaluated. The solubility of measured metals in infusion extracts varied widely and ranged from 0 to 59.3%. Among the studied elements, Cr, Pb, and Cd showed the lowest rates of solubility and Ni had the highest rates of solubility. The amount of toxic metals and essential mineral elements that one may take up through consumption of black tea infusion was estimated. The amount of realizing each element into tea infusions and acceptable daily intake, for safety consumption of black tea, was compared.

All guidelines, protocols and recommendations underline the importance of therapeutic education as a key element in asthma management and control. Considerable evidence supports the efficacy and effectiveness of this measure. Health personnel, as well as patients and their parents, can and should be educated with two main objectives: to achieve the best possible quality of life and to allow self control of the disease. These goals can be attained through an educational process that should be individually tailored, continuous, progressive, dynamic, and sequential. The process poses more than a few difficulties involving patients, health professionals, and the health systems. Knowledge of the various psychological factors that can be present in asthmatic patients, as well as the factors related to the highly prevalent phenomenon of non-adherence, is essential. Awareness of the factors influencing physician-patient-family communication is also highly important to achieve the objectives set in therapeutic education. The educational process helps knowledge and abilities to be acquired and allows attitudes and beliefs to be modified. Patients and caregivers should be provided with an individual written action plan based on symptoms and/or forced expiratory volume in 1 second. Periodic follow-up visits are also required.

2010-01-01

Substantial global and national commitment will be required for current healthcare systems and health professional practices to become learning care systems utilizing information and communications technology (ICT) empowered by informatics. To engage this multifaceted challenge, a vision is required that shifts the emphasis from silos of activities toward integrated systems. Successful systems will include a set of essential elements, e.g., a sufficient ICT infrastructure, evolving health care processes based on evidence and harmonized to local cultures, a fresh view toward educational preparation, sound and sustained policy support, and ongoing applied research and development. Increasingly, leaders are aware that ICT empowered by informatics must be an integral part of their national and regional visions. This paper sketches out the elements of what is needed in terms of objectives and some steps toward achieving them. It summarizes some of the progress that has been made to date by the American and International Medical Informatics Associations working separately as well as collaborating to conceptualize informatics capacity building in order to bring this vision to reality in low resource nations in particular.

The main purpose of the present study is to assess human dietary exposure to essential and non-essential trace elements via consumption of selected homegrown foodstuffs. Twelve essential and non-essential trace elements (Cd, Co, Cu, Cr, Hg, Mo, Ni, Pb, Sb, Se, Zn and As) were detected in various homegrown foodstuffs. Detailed questionnaires were also applied among a sample of the local population to collect information on sociodemographic characteristics. The results of the present study clearly indicate that the majority of the trace elements are at highly elevated levels in the studied foodstuffs, in comparison to international recommendations. The maximum measured levels of ETE and NETE are as follows [μgkg(-1)]: Cd 873, Co 1370, Cu 21700, Cr 59633, Hg 26, Mo 6460, Ni14.5, Pb 11100, Sb 181, Se 0.30, Zn 102 and As 693. Additionally, age, body mass index and gender were significantly associated with levels of dietary exposure. Further research is warranted on the potential health implication of this exposure. The study merges the accumulation of ETE and NETE in home-grown foodstuffs and reflects considerably high health risks for inhabitants. Copyright © 2016 Elsevier B.V. All rights reserved.

Maternal breast milk is a unique biological matrix that contains essential micronutrients. Potentially heavy metals may also affect infants' health and growth through maternal breast milk. The purpose of this study was to determine and compare the essential elements and heavy metals of maternal breast milk of nursery mothers residing in Şanlıurfa province, Turkey. Maternal breast milk concentrations of sodium, magnesium, phosphorus, potassium, calcium, iron, copper, zinc, arsenic, and lead were analyzed in a random sample of the first time in urban and suburban nursery Turkish mothers ( n : 42). Eight essential elements and two heavy metals were analyzed using ICP-MS after microwave digestion. For bivariate analyses of variables, we use nonparametric Spearman's correlation coefficient test. The mean concentrations of essential elements and heavy metals were as follows: sodium 330 ± 417 mg/L, magnesium 32.6 ± 15.5 mg/L, phosphorus 156 ± 46.2 mg/L, potassium 488 ± 146 mg/L, calcium 193 ± 53.2 mg/L, iron 1.65 ± 1.43 mg/L, copper 0.54 ± 0.46 mg/L, zinc 2.89 ± 3.23 mg/L, arsenic < 1  μ g/L, and lead < 1  μ g/L. Concentrations of heavy metals in maternal breast milk may have the important implication that it is not affected by environmental pollution in this province. This study provides reliable information about maternal breast milk concentrations of nursery mothers residing in Şanlıurfa, Turkey, and also compares the relations between essential elements and socioeconomic conditions, residing areas, and using copper equipment for food preparation of which some have not previously been reported.

2005-03-01

The purpose of this study is to propose a framework drawing on theoretical and empirical science education research that explains the common prominent field-based components of the handful of persistent and successful Earth science education programs designed for indigenous communities in North America. These programs are primarily designed for adult learners, either in a postsecondary or in a technical education setting and all include active collaboration between local indigenous communities and geoscientists from nearby universities. Successful Earth science curricula for indigenous learners share in common an explicit emphasis on outdoor education, a place and problem-based structure, and the explicit inclusion of traditional indigenous knowledge in the instruction. Programs sharing this basic design have proven successful and popular for a wide range of indigenous cultures across North America. We present an analysis of common field-based elements to yield insight into indigenous Earth science education. We provide an explanation for the success of this design based in research on field-based learning, Native American learning styles research, and theoretical and empirical research into the nature and structure of indigenous knowledge. We also provide future research directions that can test and further refine our understanding of best practices in indigenous Earth science education.

To evaluate whether implementation factors or fidelity moderate chronic disease self-management education program outcomes. Meta-analysis of 34 Arthritis Self-Management Program and Chronic Disease Self-Management Program studies. Community. N = 10 792. Twelve implementation factors: program delivery fidelity and setting and leader and participant characteristics. Eighteen program outcomes: self-reported health behaviors, physical health status, psychological health status, and health-care utilization. Meta-analysis using pooled effect sizes. Modest to moderate statistically significant differences for 4 of 6 implementation factors; these findings were counterintuitive with better outcomes when leaders and participants were unpaid, leaders had less than minimum training, and implementation did not meet fidelity requirements. Exploratory study findings suggest that these interventions tolerate some variability in implementation factors. Further work is needed to identify key elements where fidelity is essential for intervention effectiveness.

Cyberbullying: the challenge to define.

Cyberbullying is a reality of the digital age. To address this phenomenon, it becomes imperative to understand exactly what cyberbullying is. Thus, establishing a workable and theoretically sound definition is essential. This article contributes to the existing literature in relation to the definition of cyberbullying. The specific elements of repetition, power imbalance, intention, and aggression, regarded as essential criteria of traditional face-to-face bullying, are considered in the cyber context. It is posited that the core bullying elements retain their importance and applicability in relation to cyberbullying. The element of repetition is in need of redefining, given the public nature of material in the online environment. In this article, a clear distinction between direct and indirect cyberbullying is made and a model definition of cyberbullying is offered. Overall, the analysis provided lends insight into how the essential bullying elements have evolved and should apply in our parallel cyber universe.

Undergraduate Surgical Education is becoming an essential element in the training of the future generation of safe and efficient surgeons. Essential Skills in the Management of Surgical Cases (ESMSC), is an international, joint applied surgical science and simulation-based learning wet lab course. We performed a review of the existing literature on the topic of undergraduate surgical education. Following that, we analyzed the feedback questionnaire received 480 from 2 recent series of ESMSC courses (May 2015, n = 49 and November 2015, n = 40), in order to evaluate European Union students' (UK, Germany, Greece) views on the ESMSC course, as well as on the undergraduate surgical education. Results Using a 10 point graded scale, the overall ESMSC concept was positively evaluated, with a mean score of 9.41 ± 0.72 (range: 8-10) and 8.94 ± 1.1 (range: 7-10). The majority of delegates from both series [9.86 ± 0.43 (range: 8-10) and 9.58 ± 0.91 (range: 6-10), respectively] believed that ESMSC should be incorporated in the undergraduate surgical curriculum. Comparison of responses from the UK to the Greek Medical Student, as well as the findings from the third and fourth year versus the fifth and sixth year Medical Students, revealed no statistically significant differences pertaining to any of the questions (p > 0.05). Current evidence in the literature supports the enhancement of surgical education through the systematic use of various modalities that provide Simulation-Based Training (SBT) hands-on experience, starting from the early undergraduate level. The findings of the present study are in agreement with these previous reports.

Rethinking programme evaluation in health professions education: beyond 'did it work?'.

For nearly 40 years, outcome-based models have dominated programme evaluation in health professions education. However, there is increasing recognition that these models cannot address the complexities of the health professions context and studies employing alternative evaluation approaches that are appearing in the literature. A similar paradigm shift occurred over 50 years ago in the broader discipline of programme evaluation. Understanding the development of contemporary paradigms within this field provides important insights to support the evolution of programme evaluation in the health professions. In this discussion paper, we review the historical roots of programme evaluation as a discipline, demonstrating parallels with the dominant approach to evaluation in the health professions. In tracing the evolution of contemporary paradigms within this field, we demonstrate how their aim is not only to judge a programme's merit or worth, but also to generate information for curriculum designers seeking to adapt programmes to evolving contexts, and researchers seeking to generate knowledge to inform the work of others. From this evolution, we distil seven essential elements of educational programmes that should be evaluated to achieve the stated goals. Our formulation is not a prescriptive method for conducting programme evaluation; rather, we use these elements as a guide for the development of a holistic 'programme of evaluation' that involves multiple stakeholders, uses a combination of available models and methods, and occurs throughout the life of a programme. Thus, these elements provide a roadmap for the programme evaluation process, which allows evaluators to move beyond asking whether a programme worked, to establishing how it worked, why it worked and what else happened. By engaging in this process, evaluators will generate a sound understanding of the relationships among programmes, the contexts in which they operate, and the outcomes that result from them. © Blackwell Publishing Ltd 2013.

THE BRITISH AND CURRICULUM DEVELOPMENT IN WEST AFRICA: A HISTORICAL STUDY - Only recently have African nations begun to make their way towards establishing genuinely autonomous education systems incorporating elements of indigenous culture. The present study examines the historical development of curriculum in British West Africa in its links with the educational activities of the early Christian missionaries and the imposition of British colonial rule. For over 300 years, the curriculum content was essentially European in nature. African interests and cultural practices were largely excluded, as "bookwork" was favored over "handwork". The colonial curriculum also helped introduce a new social order to West Africa, leading to the rise of new local elites reading, writing, and speaking foreign European languages. This study explores how the idea of a "civilized" person, promoted through the colonial school curriculum, developed new local elites with different sets of values and expectations that often made them strangers in their own societies. It also describes the connection between this curriculum and the repeated failure of education-reform efforts.

The progress of information and communication technologies has strongly influenced changes in healthcare and laboratory medicine. E-learning, the learning or teaching through electronic means, contributes to the effective knowledge translation in medicine and healthcare, which is an essential element of a modern healthcare system and for the improvement of patient care. E-learning also represents a great vector for the transfer knowledge into laboratory practice, stimulate multidisciplinary interactions, enhance continuing professional development and promote laboratory medicine. The European Federation of Laboratory Medicine (EFLM) has initiated a distance learning program and the development of a collaborative network for e-learning. The EFLM dedicated working group encourages the organization of distance education programs and e-learning courses as well as critically evaluate information from courses, lectures and documents including electronic learning tools. The objectives of the present paper are to provide some specifications for distance learning and be compatible with laboratory medicine practices.

Determination of essential and toxic elements in clay soil commonly consumed by pregnant women in Tanzania

Mwalongo, D.; Mohammed, N. K.

2013-10-01

A habit of eating clay soil especially among pregnant women is a common practice in Tanzania. This practice known as geophagy might introduce toxic elements in the consumer's body to endanger the health of the mother and her child. Therefore it is very important to have information on the elemental composition of the eaten soil so as to assess the safety nature of the habit. In this study 100 samples of clay soil, which were reported to be originating from five regions in Tanzania and are consumed by pregnant women were analyzed to determine their levels of essential and toxic elements. The analysis was carried out using energy dispersive X-ray fluorescent technique (EDXRF) of Tanzania Atomic Energy Commission, Arusha. Essential elements Fe, Zn, Cu, Se and Mn and toxic elements As, Pb, Co, Ni, U and Th were detected in concentrations above WHO permissible limits in some of the samples. The results from this study show that the habit of eating soil is exposing the pregnant mothers and their children to metal toxicity which is detrimental to their health. Hence, further actions should be taken to discourage the habit of eating soil at all levels.

Trace elements (TEs) are an essential component of parenteral nutrition (PN). Over the last few decades, there has been increased experience with PN, and with this knowledge more information about the management of trace elements has become available. There is increasing awareness of the effects of deficiencies and toxicities of certain trace elements. Despite this heightened awareness, much is still unknown in terms of trace element monitoring, the accuracy of different assays, and current TE contamination of solutions. The supplementation of TEs is a complex and important part of the PN prescription. Understanding the role of different disease states and the need for reduced or increased doses is essential. Given the heterogeneity of the PN patients, supplementation should be individualized. PMID:28452962

Education and language: A human right for sustainable development in Africa

Pre-colonial Africa was neither an educationally nor a technologically unsophisticated continent. While education was an integral part of the culture, issues of language identification and standardisation which are subject to contentious debate today were insignificant. Children learned community knowledge and history by asking questions instead of being taught in a hegemonic alien language. This article argues that education and development should take place in a broader context of human rights, and explores the links between three areas often dealt with separately, namely: language, education and development. The authors of this paper demonstrate that changing the face of the multi-dimensionalities of poverty within societies is possible only when education is constructed in a rights perspective over the favoured colonial languages, which are not an integral part of the culture and resources of a community. The authors make a distinction between the right to education and rights in education, the latter of which are found to be more significant for the challenges Africa faces. It is argued here that the elements of Amartya Sen's "threshold" conditions for inclusion in human rights and self-development in education are essential, and that a more promising architecture of education would include what the authors term meta-narrative frameworks, i.e. interrelated policies. The authors contend that the neoliberal commodification of the knowledge sector has only exacerbated human rights and capabilities deprivation - which encompasses both human and income poverty.

A maternal-effect selfish genetic element in Caenorhabditis elegans.

Selfish genetic elements spread in natural populations and have an important role in genome evolution. We discovered a selfish element causing embryonic lethality in crosses between wild strains of the nematode Caenorhabditis elegans The element is made up of sup-35 , a maternal-effect toxin that kills developing embryos, and pha-1 , its zygotically expressed antidote. pha-1 has long been considered essential for pharynx development on the basis of its mutant phenotype, but this phenotype arises from a loss of suppression of sup-35 toxicity. Inactive copies of the sup-35/pha-1 element show high sequence divergence from active copies, and phylogenetic reconstruction suggests that they represent ancestral stages in the evolution of the element. Our results suggest that other essential genes identified by genetic screens may turn out to be components of selfish elements. Copyright © 2017, American Association for the Advancement of Science.

The fundamental nature of life as a chemical system: the part played by inorganic elements.

PubMed

Williams, Robert J P

2002-02-01

In this article we show why inorganic metal elements from the environment were an essential part of the origin of living aqueous systems of chemicals in flow. Unavoidably such systems have many closely fixed parameters, related to thermodynamic binding constants, for the interaction of the essential exchangeable inorganic metal elements with both inorganic and organic non-metal materials. The binding constants give rise to fixed free metal ion concentration profiles for different metal ions and ligands in the cytoplasm of all cells closely related to the Irving-Williams series. The amounts of bound elements depend on the organic molecules present as well as these free ion concentrations. This system must have predated coding which is probably only essential for reproductive life. Later evolution in changing chemical environments became based on the development of extra cytoplasmic compartments containing quite different energised free (and bound) element contents but in feed-back communication with the central primitive cytoplasm which changed little. Hence species multiplied late in evolution in large part due to the coupling with the altered inorganic environment.

Psoriasis is a common chronic inflammatory disease of the skin that is increasingly being recognized as a systemic inflammatory disorder. Psoriatic arthritis is a well-known comorbidity of psoriasis. A rapidly expanding body of literature in various populations and settings supports additional associations between psoriasis and cardiometabolic disease, gastrointestinal disease, kidney disease, malignancies, infections, and mood disorders. The pathogenesis of comorbid disease in psoriasis patients remains unknown; however, shared inflammatory pathways, cellular mediators, genetic susceptibility, and common risk factors are hypothesized to be contributing elements. As additional psoriasis comorbidities continue to emerge, education of healthcare providers is essential to ensuring comprehensive medical care for patients with psoriasis. PMID:28212759

2018-05-01

The criticality of raw materials has become an important issue in recent years. As the supply of certain raw materials is essential for technologically-advanced economies, the European Commission and other international counterparts have started several initiatives to secure reliable and unhindered access to raw materials. Such efforts include the EU Raw Materials Initiative, European Innovation Partnership on Raw Materials, US Critical Materials Institute, and others. In this paper, the authors present a multi-faceted and multi-national review of the essentials for the critical raw materials (CRMs) Co, Nb, W, and rare earth elements (REEs). The selected CRMs are of specific interest as they are considered relevant for emerging technologies and will thus continue to be of increasing major economic importance. This paper presents a ‘sustainability evaluation’ for each element, including essential data about markets, applications and recycling, and possibilities for substitution have been summarized and analysed. All the presented elements are vital for the advanced materials and processes upon which modern societies rely. These elements exhibit superior importance in ‘green’ applications and products subject to severe conditions. The annual production quantities are quite low compared to common industrial metals. Of the considered CRMs, only Co and REE gross production exceed 100 000 t. At the same time, the prices are quite high, with W and Nb being in the range of 60 USD kg‑1 and some rare earth compounds costing almost 4000 USD kg‑1. Despite valiant effort, in practice some of the considered elements are de facto irreplaceable for many specialized applications, at today’s technological level. Often, substitution causes a significant loss of quality and performance. Furthermore, possible candidates for substitution may be critical themselves or available in considerably low quantities. It can be concluded that one preferred approach for the investigated elements could be the use of secondary resources derived from recycling. W exhibits the highest recycling rate (37%), whereas Co (16%), Nb (11%) and rare earths (~0%) lag behind. In order to promote recycling of these essential elements, financial incentives as well as an improvement of recycling technologies would be required.

To evaluate the levels of some essential elements in thalassemic patients in Mosul, Iraq. One hundred and five thalassemic blood transfusion dependent children, 2.5-18 years of age attending Ibn-Al-Atheer teaching hospital in Mosul City, Iraq, during 2005, were used in this study. Fifty-four healthy subjects served as a control group. Patients were allocated in a non-randomized prospective cross-sectional hospital based study. Essential elements levels were estimated. The mean, standard deviation, correlation coefficient, and z-test were used. P-values <0.05 were considered statistically significant. Low serum zinc, and magnesium, and high serum copper, and potassium levels were found among the 105 thalassemic patients compared to the 54 controls. Levels of calcium, phosphate, and sodium were within normal limits. Fluctuations in the essential elements levels seem to be related to the different complications associated with the disease. Zinc deficiency may be attributed to hyperzincuria resulted from the release of Zn from hemolyzed red cells. Hypercupremia occurs in acute and chronic infections and hemochromatosis, which is a principal complication of thalassemia. Increased Na levels may be due to renal damage. Hypomagnesemia may occur due to hypoparathyroidism.

Chu, Gregory H.; Hwang, Chul Sue; Choi, Jongnam

2018-05-01

This paper is predicated on the body of literature that supports a theoretical concept that middle and high school age children possess the cognitive ability to understand thematic maps and achieve some degree of cartographic literacy. In 2006, the US National Research Council (NRC) of the National Academies published a landmark book on Learning to Think Spatially. This book documented essential secondary education components and various aspects of teaching spatial thinking. The NRC defines spatial thinking as "a form of thinking based on a constructive amalgam of three elements: concepts of space, tools of representation, and processes of reasoning" (NRC, 2006, ix). This paper is an attempt to document and understand some of the attributes associated with these three elements. Specifically, it aims to find ways that can effectively contribute to the teaching of these elements associated with spatial thinking. The National Atlas of Korea is chosen for lesson plan development because it is well-designed and provides a range of contents and comprehensiveness that are ideal; in addition, it is freely accessible online and downloadable (http://nationalatlas.ngii.go.kr/). Four master geography teachers were invited to examine the Atlas to conceive and develop Advanced Placement Human Geography (APHG) lesson plans. Four lesson plans were written and have continually been implemented in classrooms to over 800 students in the States of Utah, Georgia, Minnesota, and Tennessee since the 2015 Fall semester. Results are presented in this paper.

As the population demographics for the United States (U.S.) shift towards increasing diversity, it is essential that nurses provide culturally competent care. Cultural sensitivity has been identified as a major curricular element in the American Association of Colleges of Nursing's (AACN) The Essentials of Baccalaureate Education for Professional Nursing Practice. Thus it is imperative that nursing faculty use effective strategies to help nursing students develop cultural sensitivity and competence. Educational workshops focusing on cultural diversity are usually designed to increase people's cultural sensitivity. The purpose of this study was to assess the effectiveness of a cultural diversity forum on nursing students' cultural sensitivity as measured by their openness to diversity. A convenience sample of students was recruited from a public university in the southeastern United States. The workshop was designed as a forum that combined a keynote presentation, shared meal, and a small group interactional activity. Cultural sensitivity was measured using the Openness to Diversity/Challenge Scale (ODCS), and was administered to students before and after the forum. A convenience sample of 47 students agreed to participate and completed both the pretest and posttest. Following the workshop, the students had more cultural sensitivity as measured by their scores on the ODCS (Wilcoxin Signed-Rank test z= -3.286, p = 0.001). The findings suggested that an educational format like the cultural diversity forum can promote students' cultural sensitivity. Further research needs to continue to focus on the effectiveness of strategies to increase the cultural sensitivity of baccalaureate nursing students.

Pregnant and lactating women and infants are vulnerable population groups for adverse effects of toxic metals due to their high nutritional needs and the resultant increased gastrointestinal absorption of both, essential and toxic elements. Although breastfeeding is recommended for infants worldwide, as human milk is the best source of nutrients and other required bioactive factors, it is also a pathway of maternal excretion of toxic substances including toxic metals and thus a source of infant exposure. The aim of this research was to assess health risks in breastfeeding women in the coastal area of the Republic of Croatia and their infants (N=107) due to maternal exposure to Cd and Pb via cigarette smoking, and Hg via seafood and dental amalgam fillings, and their interaction with essential elements. Biological markers of exposure were the concentrations of main toxic metals Pb, Cd and Hg in maternal blood and three types of breast milk throughout lactation stages. Biological markers of effects were the levels of essential elements Ca, Fe, Cu, Zn and Se in maternal serum and breast milk. With regard to cigarette smoking as a source of exposure to Cd and Pb, there were effects of smoking on Cd concentration in blood and correlations between the smoking index and Cd concentrations in maternal blood (ρ=0.593; P<0.001) and mature milk (ρ=0.271; P=0.011) and Pb concentration in transitional milk (ρ=0.280; P=0.042). Regarding fish, we found correlations between weekly consumption frequency and total Hg concentrations in maternal blood (ρ=0.292; P=0.003) and mature milk (ρ=0.303; P=0.003). The number of dental amalgam fillings correlated with total Hg concentrations in colostrum (ρ=0.489; P=0.005) and transitional milk (ρ=0.309; P=0.018). As for the essential element status, only Se levels in maternal serum decreased by 10% in persons who continued smoking during pregnancy compared to non-smokers. In conclusion, the levels of main toxic metals Cd, Pb and Hg and essential elements Ca, Fe, Cu, Zn and Se in maternal blood and three types of breast milk samples in the studied area of coastal Croatia showed no risk of disrupted essential element levels with regard of toxic metal exposure in both breastfeeding women and their infants.

Jenkins, D M

The coordinator provides parent education, teacher and staff inservice training, team-teaching experiences, student counseling and a broad range of support activities related to the wider community as well as to the schools involved. The need for a coordinator for programs may depend on size and/or diversity of the school population, professional readiness of teachers and types of programs to be implemented. Despite the advances made in the Pomona program, there continue to be such problems as occasional resistance from special interest groups, administrators and school staff, individual instructors' personal value conflicts, transitional nature of student population and turnover in teacher personnel. A coordinator for sexuality programs is certainly not a total remedy for such problems in all school districts; but as an essential element in the solution of those problems, he/she provides an approach which will help school districts in initiating and implementing programs with a greater degree of success.

Ternary Complex Factors and Cofactors Are Essential for Human T-Cell Leukemia Virus Type 1 Tax Transactivation of the Serum Response Element

2000-01-01

The human T-cell leukemia virus type 1 Tax protein activates the expression of cellular immediate early genes controlled by the serum response element (SRE), which contains both the serum response factor (SRF) binding element (CArG box) and the ternary complex factor (TCF) binding element (Ets box). We show that TCF binding is necessary for Tax activation of the SRE and that Tax directly interacts with TCFs in vitro. In addition, Tax interactions with CREB binding protein (CBP) and p300- and CBP-associated factor were found to be essential for Tax activation of SRF-mediated transcription. PMID:11070040

The main challenge of higher education institutions throughout the world is to develop professionals capable of understanding and responding to the current social priorities of our countries. Given the utmost importance of addressing the complex needs of an increasingly elderly population in Mexico, the National Autonomous University of Mexico has systematically incorporated modules dealing with primary gerontological health care into several of its undergraduate programs in health sciences. The objective of this study was to analyze teacher's and student's perceptions about the current educational practices on gerontology. A cross-sectional study was carried out with a sample of 26 teachers and 122 undergraduate students. Subjects were administered interviews and responded survey instrument. A vast proportion of the teachers (42%) reported students' attitudes towards their academic training as the most important factor affecting learning in the field of gerontology, whereas students reported that the main problems of education in gerontology were theoretical (32%) and methodological (28%). In addition, 41% of students considered education on ageing matters as an essential element for their professional development, as compared to 19% of teachers (p < 0.05). Our findings suggest that the teachers' perceptions about the low importance of education on ageing matters for the professional practice of health sciences could be a negative factor for gerontology teaching.

In this study, a total of 20 elements (essential, non-essential and toxic): lithium (Li), sodium (Na), potassium (K), gallium (Ga), magnesium (Mg), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), vanadium (V), chromium (Cr), nickel (Ni), cobalt (Co), molybdenum (Mo), selenium (Se), barium (Ba), tin (Sn), arsenic (As), lead (Pb) cadmium (Cd) and mercury (Hg) in natural and cultured Cordyceps kyushuensis have been determined by means of inductively coupled plasma mass spectrometry (ICP-MS). Cultured stroma, natural stroma and natural worm were digested by microwave-assisted method before analysis. The proposed ICP-MS method was validated by analyzing a certified reference material (CRM) GBW10015 (spinach). The results of one-way analysis of variance (ANOVA) revealed that the element concentrations in the three kinds of samples were significantly different (p<0.05). Except for Mg, Zn, Cu, the values of other elemental contents were the highest in the stroma of natural C. kyushuensis. In comparison with the worm, the concentrations of determined elements in wild stroma were higher. The remarkable difference of elemental contents between cultured and natural stroma may be caused by distinct growing environment. This finding highlighted the usefulness of ICP-MS elemental analysis and enhanced the value of C. kyushuensis as a candidate for nourishing food based on its composition.

2017-01-01

Aim of this article is to review and discuss the currently used quantitative analytical method ICP-MS, which is used for quality control of pharmaceutical products. ICP-MS technique has several applications such as determination of single elements, multi element analysis in synthetic drugs, heavy metals in environmental water, trace element content of selected fertilizers and dairy manures. ICP-MS is also used for determination of toxic and essential elements in different varieties of food samples and metal pollutant present in the environment. The pharmaceuticals may generate impurities at various stages of development, transportation and storage which make them risky to be administered. Thus, it is essential that these impurities must be detected and quantified. ICP-MS plays an important function in the recognition and revealing of elemental impurities.

Lee, Jaehoon; Hulse, Nathan C; Wood, Grant M; Oniki, Thomas A; Huff, Stanley M

2016-01-01

In this study we developed a Fast Healthcare Interoperability Resources (FHIR) profile to support exchanging a full pedigree based family health history (FHH) information across multiple systems and applications used by clinicians, patients, and researchers. We used previously developed clinical element models (CEMs) that are capable of representing the FHH information, and derived essential data elements including attributes, constraints, and value sets. We analyzed gaps between the FHH CEM elements and existing FHIR resources. Based on the analysis, we developed a profile that consists of 1) FHIR resources for essential FHH data elements, 2) extensions for additional elements that were not covered by the resources, and 3) a structured definition to integrate patient and family member information in a FHIR message. We implemented the profile using an open-source based FHIR framework and validated it using patient-entered FHH data that was captured through a locally developed FHH tool.

Metal elements and their excess intake have significant influence on general health. There is only little information how Far Eastern herbs resemble European's regarding their purity and essential metal element content. The aim of the authors was to determine metal elements in different Chinese and European herbs and extracts. The studied European herbs included Calendula officinalis petals, Achillea millefolium, Epilobium parviflorum herba, Urtica dioica leaves, Crataegus monogyna flowers while Far Eastern herbs were Cordyceps sinensis, Ganoderma lucidum, Ginkgo biloba leaves, Panax ginseng and Curcuma longa roots. The analysis was performed using inductively coupled plasma optical emission spectroscopy. There was no considerable difference in essential metal elements and the Ca:Mg concentration ratio between European and Far Eastern drugs and extracts. The extracts are preferential metal element sources and their magnesium content are also advantageous, because of a shift of the Ca:Mg concentration ratio towards magnesium.

Laportea peduncularis and Urtica dioica, which are popularly known as "Nettles" belong to the plant family Urticaceae and are consumed as green vegetables or used for their medicinal benefit in many countries in Africa, Asia, Europe and America. This study aimed at investigating the effect of cooking on the macronutrient, anti-nutrient and elemental composition of L. peduncularis and U. dioica leaves. The results showed a decrease in the crude fat, ash, carbohydrate and vitamin C content with cooking, but an increase in the vitamin E content. The anti-nutrient content (cyanides, phytates and saponins) increased slightly with cooking, while the oxalate content has decreased. The concentration of essential elements in cooked L. peduncularis leaves were found to be in decreasing order of Ca > Mg > Fe > Mn > Zn > Cu > Cr > Ni > Co. Both raw and cooked leaves of nettles were found to be rich sources of macronutrients and essential elements and may be used as alternatives to commercially available nutrient supplements. Statistical analyses (principal component analysis and correlations) indicated that certain elements taken up by these plants were from common sources. Both positive and negative relationships between nutrients, anti-nutrients and elements were observed in the plant leaves.

Envisioning an oral healthcare workforce for the future.

Nash, David A

Health is critical to human well-being. Oral health is an integral component of health. One is not healthy without oral health. As health is essential to human flourishing, it is important that an oral healthcare delivery system and workforce be developed and deployed which can help ensure all citizens have the potential to access oral health care. As such access does not generally exist today, it is imperative to advance the realization of this goal and to develop a vision of an oral healthcare workforce to functionally support access. Public funding of basic oral health care is an important element to improving access. However, funding is only economically feasible if a workforce exists that is structured in a manner such that duties are assigned to individuals who have been uniquely trained to fulfill specific clinical responsibilities. An essential element of any cost-effective organizational system must be the shared responsibility of duties. Delegation must occur in the oral health workforce if competent, cost-effective care is to be provided. Desirable members of the oral health team in an efficient and effective system are as follows: generalist dentists who are educated as physicians of the stomatognathic system (oral physicians), specialist dentists, dental therapists, dental hygienists, dually trained hygienists/therapists (oral health therapists), oral prosthetists (denturists), and expanded function dental assistants (dental nurses). © 2012 John Wiley & Sons A/S.

Security culture for nuclear facilities

2017-01-01

Natural radioactive elements are part of our environment and radioactivity is a natural phenomenon. There are numerous beneficial applications of radioactive elements (radioisotopes) and radiation, starting from power generation to usages in medical, industrial and agriculture applications. But the risk of radiation exposure is always attached to operational workers, the public and the environment. Hence, this risk has to be assessed and controlled. The main goal of safety and security measures is to protect human life, health, and the environment. Currently, nuclear security considerations became essential along with nuclear safety as nuclear facilities are facing rapidly increase in cybersecurity risks. Therefore, prevention and adequate protection of nuclear facilities from cyberattacks is the major task. Historically, nuclear safety is well defined by IAEA guidelines while nuclear security is just gradually being addressed by some new guidance, especially the IAEA Nuclear Security Series (NSS), IEC 62645 and some national regulations. At the overall level, IAEA NSS 7 describes nuclear security as deterrence and detection of, and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear, other radioactive substances and their associated facilities. Nuclear security should be included throughout nuclear facilities. Proper implementation of a nuclear security culture leads to staff vigilance and a high level of security posture. Nuclear security also depends on policy makers, regulators, managers, individual employees and members of public. Therefore, proper education and security awareness are essential in keeping nuclear facilities safe and secure.

Medical education in Kazakhstan has been literally transformed in the past 10 years. Kazakhstan inherited the Soviet-time discipline-based teacher-centered system of education when no decisions could be made independently. The curriculum was mostly governed in a traditional way, with lectures being the core, little use of e-learning tools, and assessment through oral exams and multiple-choice questions. Most of the universities still preserve the subject-based curriculum with elements of integrated learning. Being the most active member of International Space Education, Karaganda State Medical University (KSMU) took the initiative to adapt the full integrated curriculum mostly based on problem-based, team-based learning, and use of virtual patient cases. The given approach was chosen because of active involvement of our University in nine Tempus and Erasmus+projects including reforming of Public Health and Nursing curriculum, human resources development, active learning, credit mobility, and move towards autonomy of medical schools. KSMU became the coordinator of two of these projects, taking its active position in internationalization of medical education. We actively use technology-based medical education, pro-actively adapting deliberate practice in acquiring essential practical skills, for which KSMU was recognized by an ASPIRE-to-Excellence Award in simulation. Kazakhstan hopes to become the leader in medical education in Central Asia and suggests other Universities in the area to adopt its approach to internationalization of medical education.

Comparison of trace element concentrations in livers of diseased, emaciated and non-diseased southern sea otters from the California coast

Infectious diseases have been implicated as a cause of high rates of adult mortality in southern sea otters. Exposure to environmental contaminants can compromise the immuno-competence of animals, predisposing them to infectious diseases. In addition to organic pollutants, certain trace elements can modulate the immune system in marine mammals. Nevertheless, reports of occurrence of trace elements, including toxic heavy metals, in sea otters are not available. In this study, concentrations of 20 trace elements (V, Cr, Mn, Co, Cu, Zn, Rb, Sr, Mo, Ag, Cd, In, Sn, Sb, Cs, Ba, Hg, Tl, Pb, and Bi) were measured in livers of southern sea otters found dead along the central California coast (n = 80) from 1992 to 2002. Hepatic concentrations of trace elements were compared among sea otters that died from infectious diseases (n = 27), those that died from non-infectious causes (n = 26), and otters that died in emaciated condition with no evidence of another cause of death (n = 27). Concentrations of essential elements in sea otters varied within an order of magnitude, whereas concentrations of non-essential elements varied by two to five orders of magnitude. Hepatic concentrations of Cu and Cd were 10- to 100-fold higher in the sea otters in this study than concentrations reported for any other marine mammal species. Concentrations of Mn, Co, Zn, and Cd were elevated in the diseased and emaciated sea otters relative to the non-diseased sea otters. Elevated concentrations of essential elements such as Mn, Zn, and Co in the diseased/emaciated sea otters suggest that induction of synthesis of metallothionein and superoxide dismutase (SOD) enzyme is occurring in these animals, as a means of protecting the cells from oxidative stress-related injuries. Trace element profiles in diseased and emaciated sea otters suggest that oxidative stress mediates the perturbation of essential-element concentrations. Elevated concentrations of toxic metals such as Cd, in addition to several other organic pollutants, may contribute to oxidative stress-meditated effects in sea otters.

Time to learn: the outlook for renewal of patient-centred education in the digital age.

Glick, T H; Moore, G T

Major forces in society and within health systems are fragmenting patient care and clinical learning. The distancing of physician and trainee from the patient undermines learning about the patient-doctor relationship. The disconnection of care and learning from one successive venue to another impedes the ability of trainees to learn about illness longitudinally. As a conceptual piece, our methods have been those of witnessing the experiences of patients, practitioners, and students over time and observing the impact of fragmented systems and changing expectations on care and learning. We have reflected on the opportunities created by digital information systems and interactive telemedicine to help renew essential relationships. Although there is, as yet, little in the literature on educational or health outcomes of this kind of technological enablement, we anticipate opportunities for a renewed focus on the patient in that patient's own space and time. Multimedia applications can achieve not only real-time connections, but can help construct a "virtual patient" as a platform for supervision and assessment, permitting preceptors to evaluate trainee-patient interactions, utilization of Web-based data and human resources, and on-line professionalism. Just as diverse elements in society are capitalizing upon digital technology to create advantageous relationships, all of the elements in the complex systems of health care and medical training can be better connected, so as to put the patient back in the centre of care and the trainee's ongoing relationship to the patient back in the centre of education.

Lanthanides are biologically non-essential elements with wide applications in technology and industry. Their concentration as environmental contaminants is, therefore, increasing. Although non-essential, lanthanides have been proposed (and even used) to produce beneficial effects in plants, even though their mechanisms of action are unclear. Recently, it was suggested that they may replace essential elements. We tested the effect of low concentrations of lanthanides on the common freshwater microalga Desmodesmus quadricauda, grown under conditions of metal ion-deficiency (lower calcium or manganese concentrations). Our goal was to test if lanthanides can replace essential metals in their functions. Physiological stress was recorded by studying growth and photosynthetic activity using a pulse amplitude modulation (PAM) fluorimeter. We found that nutrient stress reduced parameters of growth and photosynthesis, such as maximal quantum yield, relative electron transport rate, photon capturing efficiency and light saturation irradiance. After adding low concentrations of five lanthanides, we confirmed that they can produce a stimulatory effect on microalgae, depending on the nutrient (metal) deprivation. In the case of a calcium deficit, the addition of lanthanides partly alleviated the adverse effects, probably by a partial substitution of the element. In contrast, with manganese deprivation (and at even lower concentrations), lanthanides enhanced the deleterious effect on cellular growth and photosynthetic competence. These results show that lanthanides can replace essential elements, but their effects on microalgae depend on stress and the nutritional state of the microalgae, raising the possibility of environmental impacts at even low concentrations.

Should bioactive trace elements not recognized as essential, but with beneficial health effects, have intake recommendations.

PubMed

Nielsen, Forrest H

2014-10-01

Today, most nutritionists do not consider a trace element essential unless it has a defined biochemical function in higher animals or humans. As a result, even though it has been found that trace elements such as boron and silicon have beneficial bioactivity in higher animals and humans, they generally receive limited attention or mention when dietary guidelines or intake recommendations are formulated. Recently, the possibility of providing dietary intake recommendations such as an adequate intake (AI) for some bioactive food components (e.g., flavonoids) has been discussed. Boron, chromium, nickel, and silicon are bioactive food components that provide beneficial health effects by plausible mechanisms of action in nutritional and supra nutritional amounts, and thus should be included in the discussions. Although the science base may not be considered adequate for establishing AIs, a significant number of findings suggest that statements about these trace elements should be included when dietary intake guidance is formulated. An appropriate recommendation may be that diets should include foods that would provide trace elements not currently recognized as essential in amounts shown to reduce the risk of chronic disease and/or promote health and well-being.

Simulation-based methodologies are increasingly used to assess teamwork and communication skills and provide team training. Formative feedback regarding team performance is an essential component. While effective use of simulation for assessment or training requires accurate rating of team performance, examples of rater-training programs in health care are scarce. We describe our rater training program and report interrater reliability during phases of training and independent rating. We selected an assessment tool shown to yield valid and reliable results and developed a rater training protocol with an accompanying rater training handbook. The rater training program was modeled after previously described high-stakes assessments in the setting of 3 facilitated training sessions. Adjacent agreement was used to measure interrater reliability between raters. Nine raters with a background in health care and/or patient safety evaluated team performance of 42 in-situ simulations using post-hoc video review. Adjacent agreement increased from the second training session (83.6%) to the third training session (85.6%) when evaluating the same video segments. Adjacent agreement for the rating of overall team performance was 78.3%, which was added for the third training session. Adjacent agreement was 97% 4 weeks posttraining and 90.6% at the end of independent rating of all simulation videos. Rater training is an important element in team performance assessment, and providing examples of rater training programs is essential. Articulating key rating anchors promotes adequate interrater reliability. In addition, using adjacent agreement as a measure allows differentiation between high- and low-performing teams on video review. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

Obesity prevention and the Health promoting Schools framework: essential components and barriers to success.

Obesity is an important public health issue. Finding ways to increase physical activity and improve nutrition, particularly in children, is a clear priority. Our Cochrane review of the World Health Organization's Health Promoting Schools (HPS) framework found this approach improved students' physical activity and fitness, and increased fruit and vegetable intake. However, there was considerable heterogeneity in reported impacts. This paper synthesises process evaluation data from these studies to identify factors that might explain this variability. We searched 20 health, education and social-science databases, and trials registries and relevant websites in 2011 and 2013. No language or date restrictions were applied. We included cluster randomised controlled trials. Participants were school students aged 4-18 years. Studies were included if they: took an HPS approach (targeting curriculum, environment and family/community); focused on physical activity and/or nutrition; and presented process evaluation data. A framework approach was used to facilitate thematic analysis and synthesis of process data. Twenty-six studies met the inclusion criteria. Most were conducted in America or Europe, with children aged 12 years or younger. Although interventions were acceptable to students and teachers, fidelity varied considerably across trials. Involving families, while an intrinsic element of the HPS approach, was viewed as highly challenging. Several themes emerged regarding which elements of interventions were critical for success: tailoring programmes to individual schools' needs; aligning interventions with schools' core aims; working with teachers to develop programmes; and providing on-going training and support. An emphasis on academic subjects and lack of institutional support were barriers to implementation. Stronger alliances between health and education appear essential to intervention success. Researchers must work with schools to develop and implement interventions, and to evaluate their impact on both health and educational outcomes as this may be a key determinant of scalability. If family engagement is attempted, better ways to achieve this must be developed and evaluated. Further evaluations of interventions to promote physical activity and nutrition during adolescence are needed. Finally, process evaluations must move beyond simple measures of acceptability/fidelity to include detailed contextual information to illuminate exactly what works, for whom, in what contexts and why.

2016-01-01

Today's dynamic health care environment is exceedingly complex, and health care facilities across the United States are struggling to respond to changes in technology, health care reimbursement, the Affordable Care Act, and the much-anticipated nursing shortage. Mergers, acquisitions, and integrations are the current health care reality. These are proposed to increase efficiency, efficacy, quality, satisfaction, and safety while effectively reducing cost to the consumer and stabilizing the economy of the health care system. Many of these projects fail to achieve objectives, even years after the formal change in status. Clinical education departments in merged organizations are often operated in the single-facility mindset, or contain an element of the shared services model. They are not truly integrated. Development of skills in complex analysis of current state, identification of desired scope of service and expectations of performance, and articulation of the benefits of the desired future state are all essential to nursing executive practice. This article describes an experience integrating 3 legacy education departments across 21 facilities into a centralized education system. The complexity of integration activities is illustrated and outcome measures of success are discussed. Barriers, facilitators, and risks of the project are identified and evaluated.

What goes around comes around: improving faculty retention through more effective mentoring.

PubMed

Dunham-Taylor, Janne; Lynn, Cynthia W; Moore, Patricia; McDaniel, Staci; Walker, Jane K

2008-01-01

In the midst of a nursing faculty shortage, recruitment and retention of new faculty are of utmost importance if the country is to educate and graduate a sufficient number of nurses to fill the health care demands. The pressure of horizontal hostility combined with lack of support, guidance, and knowledge about the educational system makes the novice nurse faculty members vulnerable to burnout and early resignations. Mentorship is the single most influential way to successfully develop new nursing faculty, reaping the benefits of recruitment, retention, and long-term maturation of future nurse mentors. Mentoring is a developmental process designed to support and navigate the novice nurse educator through the tasks and experiences of nursing education. The essential elements of an effective mentorship program include the following: socialization, collaboration, operations, validation/evaluation, expectations, transformation, reputation, documentation, generation, and perfection. The mentoring process can lead to an upward spiral of success. If negative, the new faculty experience is at risk for a downward spiral. In this spiral, the final outcome will ultimately be the creation of productive faculty (and future nurse mentors), along with improved faculty group dynamics and teamwork, or just another vacant position.

Abstract In 100 Institutional Review Board approved consent forms (CFs), we assessed pages, reading levels, and whether they included essential elements. CF page numbers ranged from 3 to 28 (mean, 10.3) and readability ranged from grades 5.6 to 28.9 (mean, 11.6). The CF mean score for including essential elements was 90.8% (range: 63.5–100%). There were no significant differences by specialty in number of pages (p = 0.053), but surgical specialties had the highest readability (mean, 13.1), and pediatrics the lowest (10.5), p = 0.008. While approved CFs generally included the Office for Human Research Protections recommended essential elements, they were very long, and even pediatric forms, which had the lowest reading levels, were written on average at a tenth grade level. Researchers need guidance to resolve pressure between regulatory mandates and guidelines and “keeping it simple and clear.” PMID:25580939

The present study aimed to evaluate trace mineral status of organic dairy herds in northern Spain and the sources of minerals in different types of feed. Blood samples from organic and conventional dairy cattle and feed samples from the respective farms were analysed by inductively coupled plasma mass spectrometry to determine the concentrations of the essential trace elements (cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), iodine (I), manganese (Mn), molybdenum (Mo), nickel (Ni), selenium (Se) and zinc (Zn)) and toxic trace elements (arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb)). Overall, no differences between organic and conventional farms were detected in serum concentrations of essential and toxic trace elements (except for higher concentrations of Cd on the organic farms), although a high level of inter-farm variation was detected in the organic systems, indicating that organic production greatly depends on the specific local conditions. The dietary concentrations of the essential trace elements I, Cu, Se and Zn were significantly higher in the conventional than in the organic systems, which can be attributed to the high concentration of these minerals in the concentrate feed. No differences in the concentrations of trace minerals were found in the other types of feed. Multivariate chemometric analysis was conducted to determine the contribution of different feed sources to the trace element status of the cattle. Concentrate samples were mainly associated with Co, Cu, I, Se and Zn (i.e. with the elements supplemented in this type of feed). However, pasture and grass silage were associated with soil-derived elements (As, Cr, Fe and Pb) which cattle may thus ingest during grazing.

During spring of 2009, a new influenza virus AH1N1 spread in the world causing acute respiratory illness and death, resulting in the first influenza pandemic since 1968. Blood levels of potentially-toxic and essential elements of 40 pneumonia and confirmed AH1N1 were evaluated against two different groups of controls, both not infected with the pandemic strain. Significant concentrations of potentially-toxic elements (lead, mercury, cadmium, chromium, arsenic) along with deficiency of selenium or increased Zn/Cu ratios characterized AH1N1 cases under study when evaluated versus controlled cases. Deficiency of selenium is progressively observed from controls I (influenza like illness) through controls II (pneumonia) and finally pneumonia -AH1N1 infected patients. Cases with blood Se levels greater than the recommended for an optimal cut-off to activate glutathione peroxidase (12.5 μg/dL) recovered from illness and survived. Evaluation of this essential element in critical pneumonia patients at the National Institutes is under evaluation as a clinical trial. PMID:23422930

Innovation in pediatric clinical education: application of the essential competencies.

Kenyon, Lisa K; Birkmeier, Marisa; Anderson, Deborah K; Martin, Kathy

2015-01-01

At the Section on Pediatrics Education Summit in July 2012, consensus was achieved on 5 essential core competencies (ECCs) that represent a knowledge base essential to all graduates of professional physical therapist education programs. This article offers suggestions for how clinical instructors (CIs) might use the ECCs to identify student needs and guide student learning during a pediatric clinical education experience. Pediatric CIs potentially might choose to use the ECCs as a reference tool in clinical education to help (1) organize and develop general, clinic-specific clinical education objectives, (2) develop and plan individualized student learning experiences, (3) identify student needs, and (4) show progression of student learning from beginner to intermediate to entry level. The ECCs may offer CIs insights into the role of pediatric clinical education in professional physical therapist education.

Trace element accumulation in bivalve mussels Anodonta woodiana from Taihu Lake, China.

2010-11-01

Data are presented for 13 trace metals (Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, and Pb) in 38 bivalve mussels Anodonta woodiana from four separate sites (Huzhou, Dapu, Sansandao, and Manshan) around the Taihu Lake of China. All elemental concentrations generally ranked in decreasing order, Mn > Fe > Zn > As ≈ Cu ≈ Cd ≈ Se > Pb > Mo ≈ Ag, except that Cr, Co, and Ni were not detected. Anodonta woodiana was able to bioaccumulate essential Mn and toxic Cd to the extremely high level of 19,240 and 53 mg/kg dry weight, respectively. Geographical differences in the concentrations of trace elements were usually significant between sampling sites except for As and Pb, and the mussels from Sanshandao site had mostly accumulated or were contaminated with essential and toxic elements. The residue level of Cd in A. woodiana from the Sanshandao and Manshan sites appeared to be even higher than those of the essential elements Cu and Se, and exceeded the corresponding maximum residue limits of China. The present study provides the most recent information on trace element bioaccumulation or contamination in Taihu Lake and, further, suggests that A. woodiana can be used as a suitable bioindicator for inland water environmental monitoring.

2008-06-01

To assess geographic distributions of elements in the Arctic we compared essential and non-essential elements in the livers of polar bears (Ursus maritimus) collected from five regions within Canada in 2002, in Alaska between 1994 and 1999 and from the northwest and east coasts of Greenland between 1988 and 2000. As, Hg, Pb and Se varied with age, and Co and Zn with gender, which limited spatial comparisons across all populations to Cd, which was highest in Greenland bears. Collectively, geographic relationships appeared similar to past studies with little change in concentration over time in Canada and Greenland for most elements; Hg and Se were higher in some Canadian populations in 2002 as compared to 1982 and 1984. Concentrations of most elements in the polar bears did not exceed toxicity thresholds, although Cd and Hg exceeded levels correlated with the formation of hepatic lesions in laboratory animals.

1) to propose a new classification of the trace elements based on a study of the recently reported research; 2) to offer detailed and actualized information about trace elements. the analysis of the research results recently reported reveals that the advances of the molecular analysis techniques point out the importance of certain trace elements in human health. A detailed analysis of the catalytic function related to several elements not considered essential o probably essentials up to now is also offered. To perform the integral analysis of the enzymes containing trace elements informatics tools have been used. Actualized information about physiological role, kinetics, metabolism, dietetic sources and factors promoting trace elements scarcity or toxicity is also presented. Oligotherapy uses catalytic active trace elements with therapeutic proposals. The new trace element classification here presented will be of high interest for different professional sectors: doctors and other professions related to medicine; nutritionist, pharmaceutics, etc. Using this new classification and approaches, new therapeutic strategies could be designed to mitigate symptomatology related to several pathologies, particularly carential and metabolic diseases.

Little information is currently available about the content of different elements in wheat samples from the Republic of Kazakhstan. The concentrations of toxic (As, Cd, Cr, Hg, Pb, and U) and essential (Co, Cu, Fe, Mn, Ni, Se, and Zn) elements in 117 sampled wheat grains from the Republic of Kazakhstan were measured. The results indicated that the mean and maximum concentrations of most investigated elements (As, Cd, Co, Cr, Mn, Se, Pb, and U) were higher in samples collected from southern Kazakhstan. The mean and maximum concentrations of toxic elements such as As, Cd, Hg, and Pb did not exceed levels specified by European, FAO, or Kazakh legislation, although the hazard quotient (HQ) values for Co, Cu, Mn, and Zn were higher than 1 and the hazard index (HI) was higher than 1 for samples collected from all areas of Kazakhstan. This indicates that there should be concern about the potential hazards of the combination of toxic elements in Kazakh wheat.

Applying the cognitive theory of multimedia learning: an analysis of medical animations.

2013-04-01

Instructional animations play a prominent role in medical education, but the degree to which these teaching tools follow empirically established learning principles, such as those outlined in the cognitive theory of multimedia learning (CTML), is unknown. These principles provide guidelines for designing animations in a way that promotes optimal cognitive processing and facilitates learning, but the application of these learning principles in current animations has not yet been investigated. A large-scale review of existing educational tools in the context of this theoretical framework is necessary to examine if and how instructional medical animations adhere to these principles and where improvements can be made. We conducted a comprehensive review of instructional animations in the health sciences domain and examined whether these animations met the three main goals of CTML: managing essential processing; minimising extraneous processing, and facilitating generative processing. We also identified areas for pedagogical improvement. Through Google keyword searches, we identified 4455 medical animations for review. After the application of exclusion criteria, 860 animations from 20 developers were retained. We randomly sampled and reviewed 50% of the identified animations. Many animations did not follow the recommended multimedia learning principles, particularly those that support the management of essential processing. We also noted an excess of extraneous visual and auditory elements and few opportunities for learner interactivity. Many unrealised opportunities exist for improving the efficacy of animations as learning tools in medical education; instructors can look to effective examples to select or design animations that incorporate the established principles of CTML. © Blackwell Publishing Ltd 2013.

Introduction Colorectal cancer is one of the most common cancers worldwide. Incidence rates of large intestine cancer indicate a role of environmental and occupational factors. The role of essential elements and their interaction with toxic metals can contribute to the explanation of a complex mechanism by which large intestine cancer develops. Bearing this in mind, determining the levels of essential and toxic elements in tissues (organs), as well as in body fluids, seems to shed light on their role in the mode of action in malignant disease. Aim Determination of the levels of cadmium, zinc, copper, selenium, calcium, magnesium, and iron in large intestine malignant tissue. Material and methods Two intraoperative intestine sections were investigated: one from the malignant tissue and the other one from the normal tissue, collected from each person with diagnosed large intestine cancer. Cadmium, zinc, copper, calcium, magnesium, and iron levels were determined with atomic absorption spectrometry, and selenium levels by spectrofluorimetric method. Results The levels of copper, selenium, and magnesium were higher in the malignant than in normal tissues. In addition, the zinc/copper and calcium/magnesium relationship was altered in malignant tissue, where correlations were lower compared to non-malignant tissue. Conclusions The results seems to demonstrate disturbed homeostasis of some essential elements. However, it is hard to confirm their involvement in the aetiology of colorectal cancer. PMID:27110307

An Examination of Black Science Teacher Educators' Experiences with Multicultural Education, Equity, and Social Justice

Atwater, Mary M.; Butler, Malcolm B.; Freeman, Tonjua B.; Carlton Parsons, Eileen R.

2013-12-01

Diversity, multicultural education, equity, and social justice are dominant themes in cultural studies (Hall in Cultural dialogues in cultural studies. Routledge, New York, pp 261-274, 1996; Wallace 1994). Zeichner (Studying teacher education: The report of the AERA panel on research and teacher education. Lawrence Erlbaum Associates, Mahwah, pp 737-759, 2005) called for research studies of teacher educators because little research exists on teacher educators since the late 1980s. Thomson et al. (2001) identified essential elements needed in order for critical multiculturalism to be infused in teacher education programs. However, little is known about the commitment and experiences of science teacher educators infusing multicultural education, equity, and social justice into science teacher education programs. This paper examines twenty (20) Black science teacher educators' teaching experiences as a result of their Blackness and the inclusion of multicultural education, equity, and social justice in their teaching. This qualitative case study of 20 Black science teacher educators found that some of them have attempted and stopped due to student evaluations and the need to gain promotion and tenure. Other participants were able to integrate diversity, multicultural education, equity and social justice in their courses because their colleagues were supportive. Still others continue to struggle with this infusion without the support of their colleagues, and others have stopped The investigators suggest that if science teacher educators are going to prepare science teachers for the twenty first century, then teacher candidates must be challenged to grapple with racial, ethnic, cultural, instructional, and curricular issues and what that must mean to teach science to US students in rural, urban, and suburban school contexts.

2014-04-01

The levels of trace elements (As, Cd, Cr, Cu, Fe, Ni, Pb, Se, and Zn) in eight species of cultured freshwater fishes from Jiangxi province were determined by inductively coupled plasma-mass spectroscopy. All the studied trace element levels in fish muscles from Jiangxi province did not exceed Chinese national standard and European Union standard, and they were often lower than previous studies. The calculated target hazard quotient values for all the studied trace elements in fish samples were much less than 1, suggesting that the studied trace elements in fish muscles from Jiangxi province had not pose obvious health hazards to consumers. As and Cd concentrations in northern snakehead were much higher than that in other fishes, demonstrating that this fish species could be valuable as a bioindicator of As and Cd in environmental surveys. In addition, the highest concentrations of Fe, Zn, and moderate contents of other essential trace elements in crucian carp indicated that crucian carp could be a good nutrient source of essential trace elements for human health.

"Take in two parks and call me in the morning" - Perception of parks as an essential component of our healthcare system.

As a feature of the built neighborhood environment, parks have been associated with a range of positive health outcomes. Recognition of these contributions has prompted advocates to suggest parks are a part of our healthcare system. Despite these developments, park investments have declined over the past decade nationally, lagging behind expenditures on other community services such as health. Perhaps the idea of parks as a solution to the nation's health concerns has not diffused across the population. To date, however, public perception of parks' role in healthcare has not been documented. This study responds to this gap by assessing whether parks are perceived as an essential part of the healthcare system. Self-administered surveys were completed by a statewide sample of Pennsylvania adults (2014) and by a sample of primary care clinic visitors in Hershey, Pennsylvania (2015). Participants from both studies were asked the extent they agreed with the following statement: Parks, trails, and open space are an essential component of our healthcare system. Response was also compared across demographic characteristics to assess whether this belief was universally held. Findings indicate 73% of the statewide sample and 68% of the clinical sample agreed parks, trails, and open space are an essential element of the healthcare system. Males, those with lower levels of educational attainment, and rural residents were statistically less likely to agree with this statement. Results indicate widespread belief in parks as an essential part of the healthcare system, suggesting consideration of health-sector investments in these settings.

2012-01-01

Since the University of Chicago Health Management program was first initiated in 1932, programs and health delivery organizations have dealt with the issue of how to best provide a meaningful transition from academia to entry-level management. Today, new challenges face the same old questions: New federal legislation and increased demand for a finite supply of services cause increased revenue and expense pressures and result in the need for a higher performance level by a well-coordinated management team. In addressing these challenges, mentoring is an essential requirement for survival and success in health services. The long-term success of future practitioners will require both an understanding and incorporation of mentoring in their skill set. The University of Virginia Medical Center recently sponsored a health management education summit to examine the role of mentoring in health services administration education. Leading the program were John Westerman, former interim president of Association of University Programs in Healthcare Administration and chief executive officer emeritus of the University of Minnesota Health System, and R. Edward Howell, chief executive officer of the University of Virginia Medical Center. Summit participants included individuals who had completed administrative fellowship training programs. What follows is a review of the discussions during the summit, including a valuation of the health services fellowship as a learning experience as well as structure and essential elements of administrative mentoring programs.

The article discuses the contribution of the tourism in the development of the regional education. Then the tourist virtues of Southern Podlasie and their use in the didactic and educational process were presented. The role of school in the implementation of the idea of regionalism was justified. It was introduced in the system of Polish education together with the school reform in 1999 as a intersubjective trial, which was called regional education. In the preface there was emphasized the meaning of regionalism in the contemporary world and its close connection with tourism. Using of tourist virtues (such as natural and anthropogenic virtues) in the process of regional education in South Podlasie was discussed. Simultaneously the regional education issue, which is being systematically introduced to nursery schools and other schools of South Podlasie, was exhibited. An important element of the program of the cultural heritage in the region is ecological education. For that reason the importance and results of nature contests and actions for students from primary schools and secondary school of the region was discussed. The author of this article was trying to prove that the essential component of regional education is cultivation of local traditions. These traditions are connected with Podlasie folklore because the culture and folk art in that region have special importance in the local community and contribute to its integration. In conclusion, pedagogical aspects of tourism, especially: shaping of socialization, individuality, creative work, companionship and others, were specified.

Understanding the impact that interprofessional education and collaborative practice (IPECP) might have on triple aim patient outcomes is of high interest to health care providers, educators, administrators, and policy makers. Before the work undertaken by the National Center for Interprofessional Practice and Education at the University of Minnesota, no standard mechanism to acquire and report outcome data related to interprofessional education and collaborative practice and its effect on triple aim outcomes existed. This article describes the development and adoption of the National Center Data Repository (NCDR) designed to capture data related to IPECP processes and outcomes to support analyses of the relationship of IPECP on the Triple Aim. The data collection methods, web-based survey design and implementation process are discussed. The implications of this informatics work to the field of IPECP and health care quality and safety include creating standardized capacity to describe interprofessional practice and measure outcomes connecting interprofessional education and collaborative practice to the triple aim within and across sites/settings, leveraging an accessible data collection process using user friendly web-based survey design to support large data scholarship and instrument testing, and establishing standardized data elements and variables that can potentially lead to enhancements to national/international information system and academic accreditation standards to further team-based, interprofessional, collaborative research in the field.

2007-01-01

Background The main challenge of higher education institutions throughout the world is to develop professionals capable of understanding and responding to the current social priorities of our countries. Given the utmost importance of addressing the complex needs of an increasingly elderly population in Mexico, the National Autonomous University of Mexico has systematically incorporated modules dealing with primary gerontological health care into several of its undergraduate programs in health sciences. The objective of this study was to analyze teacher's and student's perceptions about the current educational practices on gerontology. Methods A cross-sectional study was carried out with a sample of 26 teachers and 122 undergraduate students. Subjects were administered interviews and responded survey instrument. Results A vast proportion of the teachers (42%) reported students' attitudes towards their academic training as the most important factor affecting learning in the field of gerontology, whereas students reported that the main problems of education in gerontology were theoretical (32%) and methodological (28%). In addition, 41% of students considered education on ageing matters as an essential element for their professional development, as compared to 19% of teachers (p < 0.05). Conclusion Our findings suggest that the teachers' perceptions about the low importance of education on ageing matters for the professional practice of health sciences could be a negative factor for gerontology teaching.

2015-10-07

The health behaviours of pregnant women with very severe obesity are not known, though these women are at high risk of pregnancy complications. We carried out a prospective case-control study including 148 very severely obese (BMI >40 kg/m²) and 93 lean (BMI <25 kg/m²) pregnant women. Diet, physical activity, smoking, alcohol and folic acid consumption were assessed by questionnaire in early and late (16 and 28 weeks gestation) pregnancy. Circulating levels of iron, vitamin B12 and folate and other essential trace elements and minerals were measured in a subset at each time point. The findings biochemically confirmed that very severely obese women consumed diets that were energy-rich but poor in essential micronutrients. A third of all women met physical activity recommendations for pregnancy. A third of very severely obese women and two thirds of lean women took folic acid supplements prior to pregnancy. Very severely obese women were more likely to smoke but less likely to drink alcohol than lean women (all p < 0.05). Women with very severe obesity have low self-reported intakes and circulating levels of essential micronutrients in pregnancy and few follow current recommendations for pregnancy nutrition and lifestyle. These high-risk women represent a group to target for education about health behaviours prior to and during pregnancy.

Concentrations of 17 elements, including mercury, and their relationship to fitness measures in arctic shorebirds and their eggs.

Hargreaves, Anna L; Whiteside, Douglas P; Gilchrist, Grant

2010-07-15

Exposure to contaminants is one hypothesis proposed to explain the global decline in shorebirds, and this is of particular concern in the arctic. However, little information exists on contaminant levels in arctic-breeding shorebirds, especially in Canada. We studied potential contaminants in three biparental shorebird species nesting in Nunavut, Canada: ruddy turnstones (Arenaria interpres), black-bellied plovers (Pluvialis squatarola) and semipalmated plovers (Charadrius semipalmatus). Blood, feathers and eggs were analyzed for As, Be, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Tl, V, and Zn. We assessed whether element concentrations a) differed among species and sexes, b) were correlated among pairs and their eggs, and c) were related to fitness endpoints, namely body condition, blood-parasite load, nest survival days, and hatching success. Non-essential elements were found at lower concentrations than essential elements, with the exception of Hg. Maximum Hg levels in blood approached those associated with toxicological effects in other bird species, but other elements were well below known toxicological thresholds. Reproductive success was negatively correlated with paternal Hg and maternal Pb, although these effects were generally weak and varied among tissues. Element levels were positively correlated within pairs for blood-Hg (turnstones) and feather-Ni and Cr (semipalmated plovers); concentrations in eggs and maternal blood were never correlated. Concentrations of many elements differed among species, but there was no evidence that any species had higher overall exposure to non-essential metals. In conclusion, whereas we found little evidence that exposure to the majority of these elements is leading to declines of the species studied here, Hg levels were of potential concern and both Hg and Pb warrant further monitoring.

Concentrations of 30 trace elements, Li, V, Cr, Mn, Fe, Ni, Cu, Mo, Zn, Se, Sr, Co, Al, Ti, As, Cs, Sc, Te, Ba, Ga, Pb, Sn, Cd, Sb, Ag, Tm, TI, Be, Hg and U in major cultured freshwater fish species (common carp-Cyprinus carpio, grass carp-Ctenopharyngodon idella and rainbow trout-Oncorhynchus mykiss) with the corresponding feed from 23 fish farms in Beijing, China, were investigated. The results revealed that Fe, Zn, Cu, Mn, Sr, Se were the major accumulated essential elements and Al, Ti were the major accumulated non-essential elements, while Mo, Co, Ga, Sn, Cd, Sb, Ag, Tm, U, TI, Be, Te, Pb and Hg were hardly detectable. Contents of investigated trace elements were close to or much lower than those in fish from other areas in China. Correlation analysis suggested that the elemental concentrations in those fish species were relatively constant and did not vary much with the fish feed. In comparison with the limits for aquafeeds and fish established by Chinese legislation, Cd in 37.5% of rainbow trout feeds and As in 20% of rainbow trout samples exceeded the maximum limit, assuming that inorganic As accounts for 10% of total As. Further health risk assessment showed that fish consumption would not pose risks to consumers as far as non-essential element contaminants are concerned. However, the carcinogenic risk of As in rainbow trout for the inhabitants in Beijing exceeded the acceptable level of 10(-)(4), to which more attention should be paid.

High-level evidence demonstrates midwifery continuity of care is beneficial for women and babies. Women have limited access to midwifery continuity of care models in Australia. One of the factors limiting women's access is recruiting enough midwives to work in continuity. Our research found that newly graduated midwives felt well prepared to work in midwifery led continuity of care models, were well supported to work in the models and the main driver to employing them was a need to staff the models. However limited opportunities exist for new graduate midwives to work in midwifery continuity of care. The aim of this paper therefore is to describe a conceptual model developed to enable new graduate midwives to work in midwifery continuity of care models. The findings from a qualitative study were synthesised with the existing literature to develop a conceptual model that enables new graduate midwives to work in midwifery continuity of care. The model contains the essential elements to enable new graduate midwives to work in midwifery continuity of care models. Each of the essential elements discussed are to assist midwifery managers, educators and new graduates to facilitate the organisational changes required to accommodate new graduates. The conceptual model is useful to show maternity services how to enable new graduate midwives to work in midwifery continuity of care models. Copyright © 2017 Australian College of Midwives.

Developing a professional poster: four "ps" for advanced practice nurses to consider.

PubMed

Bindon, Susan L; Davenport, Joan M

2013-01-01

Professional posters play an important role in the dissemination of knowledge and the professional development of advanced practice nurses, graduate students, and clinical faculty. Posters should be considered an integral component in communication of professional work in practice, research, and education. The invitation to submit a poster abstract is an important opportunity for clinicians and faculty alike to consider. Though sometimes misperceived as less prestigious than a podium presentation, posters add a unique element to professional and academic events. The argument is made for posters as an equal among scholarly presentation formats. The poster serves as a tremendous opportunity for collaboration between partners and a way to communicate important findings and advertise the presenters' work. For the advanced practice nurse who is a novice in presenting best practice or evidence from research trials, the poster format may be less intimidating while allowing the invaluable sharing of results. Four critical elements of professional poster development are deciding on a clear Purpose, targeting the right People, outlining key steps in the Process, and delivering a memorable Presentation. Using the "4 Ps" as cornerstones for the work of developing, preparing, and delivering the poster to an audience, the authors aim to help organize the entire process into these essential considerations. The poster, as a means of scholarly work, is a viable and essential activity, as interdisciplinary collaboration and sharing of best practice becomes the expectation for all professional development.

Marine Bioinorganic Chemistry: The Role of Trace Metals in the Oceanic Cycles of Major Nutrients

NASA Astrophysics Data System (ADS)

Morel, F. M. M.; Milligan, A. J.; Saito, M. A.

2003-12-01

The bulk of living biomass is chiefly made up of only a dozen "major" elements - carbon, hydrogen, oxygen, nitrogen, phosphorus, sodium, potassium, chlorine, calcium, magnesium, sulfur (and silicon in diatoms) - whose proportions vary within a relatively narrow range in most organisms. A number of trace elements, particularly first row transition metals - manganese, iron, nickel, cobalt, copper, and zinc - are also "essential" for the growth of organisms. At the molecular level, the chemical mechanisms by which such elements function as active centers or structural factors in enzymes and by which they are accumulated and stored by organisms is the central topic of bioinorganic chemistry. At the scale of ocean basins, the interplay of physical, chemical, and biological processes that govern the cycling of biologically essential elements in seawater is the subject of marine biogeochemistry. For those interested in the growth of marine organisms, particularly in the one-half of the Earth's primary production contributed by marine phytoplankton, bioinorganic chemistry and marine biogeochemistry are critically linked by the extraordinary paucity of essential trace elements in surface seawater, which results from their biological utilization and incorporation in sinking organic matter. How marine organisms acquire elements that are present at nano- or picomolar concentrations in surface seawater; how they perform critical enzymatic functions when necessary metal cofactors are almost unavailable are the central topics of "marine bioinorganic chemistry." The central aim of this field is to elucidate at the molecular level the metal-dependent biological processes involved in the major biogeochemical cycles.By examining the solutions that emerged from the problems posed by the scarcity of essential trace elements, marine bioinorganic chemists bring to light hitherto unknown ways to take up or utilize trace elements, new molecules, and newer "essential" elements. Focusing on molecular mechanisms involved in such processes as inorganic carbon fixation, organic carbon respiration, or nitrogen transformation, they explain how the cycles of trace elements are critically linked to those of major nutrients such as carbon or nitrogen. But we have relatively little understanding of the binding molecules and the enzymes that mediate the biochemical role of trace metals in the marine environment. In this sense, this chapter is more a "preview" than a review of the field of marine bioinorganic chemistry. To exemplify the concepts and methods of this field, we have chosen to focus on one of its most important topics: the potentially limiting role of trace elements in primary marine production. As a result we center our discussion on particular subsets of organisms, biogeochemical cycles, and trace elements. Our chief actors are marine phytoplankton, particularly eukaryotes, while heterotrophic bacteria make only cameo appearances. The biogeochemical cycles that will serve as our plot are those of the elements involved in phytoplankton growth, the major algal nutrients - carbon, nitrogen, phosphorus, and silicon - leaving aside, e.g., the interesting topic of the marine sulfur cycle. Seven trace metals provide the intrigue: manganese, iron, nickel, cobalt, copper, zinc, and cadmium. But several other trace elements such as selenium, vanadium, molybdenum, and tungsten (and, probably, others not yet identified) will assuredly add further twists in future episodes.We begin this chapter by discussing what we know of the concentrations of trace elements in marine microorganisms and of the relevant mechanisms and kinetics of trace-metal uptake. We then review the biochemical role of trace elements in the marine cycles of carbon, nitrogen, phosphorus, and silicon. Using this information, we examine the evidence, emanating from both laboratory cultures and field measurements, relevant to the mechanisms and the extent of control by trace metals of marine biogeochemical cycles. Before concluding with a wistful glimpse of the future of marine bioinorganic chemistry we discuss briefly some paleoceanographic aspects of this new field: how the chemistry of the planet "Earth" - particularly the concentrations of trace elements in the oceans - has evolved since its origin, chiefly as a result of biological processes and how the evolution of life has, in turn, been affected by the availability of essential trace elements.

The Building Healthy Urban Communities initiative presents a path for organizations partnering to improve patient outcomes with continuing education (CE) as a key component. Components of the CE initiative included traditional CE delivery formats with an essential element of adaptability and new methods, with rigorous evaluation over time that included evaluation prior to the course, immediately following the CE session, 6 to 8 weeks after the CE session, and then subsequent monthly "testlets." Outcome measures were designed to allow for ongoing adaptation of content, reinforcement of key learning objectives, and use of innovative concordant testing and retrieval practice techniques. The results after 1 year of programming suggest the stepwise skill reinforcement model is effective for learning and is an efficient use of financial and human resources. More important, its design is one that could be adopted at low cost by organizations willing to work in close partnership. J Contin Educ Nurs. 2016;47(6):283-288. Copyright 2016, SLACK Incorporated.

Opportunities for Inquiry Science in Montessori Classrooms: Learning from a Culture of Interest, Communication, and Explanation

Rinke, Carol R.; Gimbel, Steven J.; Haskell, Sophie

2013-08-01

Although classroom inquiry is the primary pedagogy of science education, it has often been difficult to implement within conventional classroom cultures. This study turned to the alternatively structured Montessori learning environment to better understand the ways in which it fosters the essential elements of classroom inquiry, as defined by prominent policy documents. Specifically, we examined the opportunities present in Montessori classrooms for students to develop an interest in the natural world, generate explanations in science, and communicate about science. Using ethnographic research methods in four Montessori classrooms at the primary and elementary levels, this research captured a range of scientific learning opportunities. The study found that the Montessori learning environment provided opportunities for students to develop enduring interests in scientific topics and communicate about science in various ways. The data also indicated that explanation was largely teacher-driven in the Montessori classroom culture. This study offers lessons for both conventional and Montessori classrooms and suggests further research that bridges educational contexts.

The Ecological Areawide Management (TEAM) of Leafy Spurge program was developed to focus research and control efforts on a single weed, leafy spurge, and demonstrate the effectiveness of a coordinated, biologically based, integrated pest management program (IPM). This was accomplished through partnerships and teamwork that clearly demonstrated the advantages of the biologically based IPM approach. However, the success of regional weed control programs horizontally across several states and provinces also requires a vertical integration of several sectors of society. Awareness and education are the essential elements of vertical integration. Therefore, a substantial effort was made to produce a wide variety of information products specifically designed to educate different segments of society. During its tenure, land managers and agency decision makers have seen the potential of using the TEAM approach to accelerate the regional control of leafy spurge. The example set by the TEAM organization and participants is viewed as a model for future weed-control efforts.

Health professions education is characterised by work-based learning and relies on effective verbal feedback. However the literature reports problems in feedback practice, including lack of both learner engagement and explicit strategies for improving performance. It is not clear what constitutes high quality, learner-centred feedback or how educators can promote it. We hoped to enhance feedback in clinical practice by distinguishing the elements of an educator's role in feedback considered to influence learner outcomes, then develop descriptions of observable educator behaviours that exemplify them. An extensive literature review was conducted to identify i) information substantiating specific components of an educator's role in feedback asserted to have an important influence on learner outcomes and ii) verbal feedback instruments in health professions education, that may describe important educator activities in effective feedback. This information was used to construct a list of elements thought to be important in effective feedback. Based on these elements, descriptions of observable educator behaviours that represent effective feedback were developed and refined during three rounds of a Delphi process and a face-to-face meeting with experts across the health professions and education. The review identified more than 170 relevant articles (involving health professions, education, psychology and business literature) and ten verbal feedback instruments in health professions education (plus modified versions). Eighteen distinct elements of an educator's role in effective feedback were delineated. Twenty five descriptions of educator behaviours that align with the elements were ratified by the expert panel. This research clarifies the distinct elements of an educator's role in feedback considered to enhance learner outcomes. The corresponding set of observable educator behaviours aim to describe how an educator could engage, motivate and enable a learner to improve. This creates the foundation for developing a method to systematically evaluate the impact of verbal feedback on learner performance.

Diabetes is one of the most prevalent chronic health conditions in the world; with a range of diabetes-related mobile applications available to the public to aid in glycaemic control and self-management. Statistically, adherence to medication is extremely low in adolescents with Type 1 Diabetes Mellitus (T1DM), therefore, this paper focuses on the research and design of an interactive and educational concept mobile application aimed at early to mid-adolescents to aid in their understanding of T1DM. As visual elements are an essential part of the design, this research outlines how visual components were designed specifically for adolescents with T1DM.

Grooming nurses at all levels of the organization to master health care executive skills is critical to the organization's success and the individual's growth. Selecting and executing next steps for nursing leadership team development is critical to success. Leaders must make it their responsibility to provide nurses with increased exposure to quality, safety, and financial data, thereby allowing nurses to translate data while achieving and sustaining successful outcomes. The work of the CNO Dashboard to measure, report, trend, and translate clinical and non-clinical outcomes must be integrated throughout all levels of nursing staff so that nursing practice is positioned to continually strive for best practice. The education and evolution of nurses as business managers is critical to building a strong RN workforce.

Microphthalmia-associated transcription factor (MITF) is the master regulator of the melanocyte lineage. To understand how MITF regulates transcription, we used tandem affinity purification and mass spectrometry to define a comprehensive MITF interactome identifying novel cofactors involved in transcription, DNA replication and repair, and chromatin organisation. We show that MITF interacts with a PBAF chromatin remodelling complex comprising BRG1 and CHD7. BRG1 is essential for melanoma cell proliferation in vitro and for normal melanocyte development in vivo. MITF and SOX10 actively recruit BRG1 to a set of MITF-associated regulatory elements (MAREs) at active enhancers. Combinations of MITF, SOX10, TFAP2A, and YY1 bind between two BRG1-occupied nucleosomes thus defining both a signature of transcription factors essential for the melanocyte lineage and a specific chromatin organisation of the regulatory elements they occupy. BRG1 also regulates the dynamics of MITF genomic occupancy. MITF-BRG1 interplay thus plays an essential role in transcription regulation in melanoma.

Mangrove forests act as a natural filter of land-derived wastewaters along industrialized tropical and sub-tropical coastlines and assist in maintaining a healthy living condition for marine ecosystems. Currently, these intertidal communities are under serious threat from heavy metal contamination induced by human activity associated with rapid urbanization and industrialization. Studies on the biotic responses of these plants to heavy metal contamination are of great significance in estuary management and maintaining coastal ecosystem health. The main objective of the present investigation was to assess the biotic response in Avicennia marina ecosystems to heavy metal contamination through the determination of metal concentrations in leaves, fine nutritive roots and underlying sediments collected in fifteen locations across Sydney Estuary (Australia). Metal concentrations (especially Cu, Pb and Zn) in the underlying sediments of A. marina were enriched to a level (based on Interim Sediment Quality Guidelines) at which adverse biological effects to flora could occasionally occur. Metals accumulated in fine nutritive roots greater than underlying sediments, however, only minor translocation of these metals to A. marina leaves was observed (mean translocation factors, TFs, for all elements <0.13, except for Mn). Translocation factors of essential elements (i.e., common plant micro-nutrients, Cu, Ni, Mn and Zn) were greater than non-essential elements (As, Cd, Co, Cr and Pb), suggesting that A. marina mangroves of this estuary selectively excluded non-essential elements, while regulating essential elements and limiting toxicity to plants. This study supports the notion that A. marina mangroves act as a phytostabilizer in this highly modified estuary thereby protecting the aquatic ecosystem from point or non-point sources of heavy metal contamination.

Linking physiology and biomineralization processes to ecological inferences on the life history of fishes.

2016-12-01

Biomineral chemistry is frequently used to infer life history events and habitat use in fishes; however, significant gaps remain in our understanding of the underlying mechanisms. Here we have taken a multidisciplinary approach to review the current understanding of element incorporation into biomineralized structures in fishes. Biominerals are primarily composed of calcium-based derivatives such as calcium carbonate found in otoliths and calcium phosphates found in scales, fins and bones. By focusing on non-essential life elements (strontium and barium) and essential life elements (calcium, zinc and magnesium), we attempt to connect several fields of study to synergise how physiology may influence biomineralization and subsequent inference of life history. Data provided in this review indicate that the presence of non-essential elements in biominerals of fish is driven primarily by hypo- and hyper-calcemic environmental conditions. The uptake kinetics between environmental calcium and its competing mimics define what is ultimately incorporated in the biomineral structure. Conversely, circannual hormonally driven variations likely influence essential life elements like zinc that are known to associate with enzyme function. Environmental temperature and pH as well as uptake kinetics for strontium and barium isotopes demonstrate the role of mass fractionation in isotope selection for uptake into fish bony structures. In consideration of calcium mobilisation, the action of osteoclast-like cells on calcium phosphates of scales, fins and bones likely plays a role in fractionation along with transport kinetics. Additional investigations into calcium mobilisation are warranted to understand differing views of strontium, and barium isotope fractionation between calcium phosphates and calcium carbonate structures in fishes.

To determine the need for a standardized renal mass reporting template by analyzing reports of indeterminate renal masses and comparing their contents to stated preferences of radiologists and urologists. The host IRB waived regulatory oversight for this multi-institutional HIPAA-compliant quality improvement effort. CT and MRI reports created to characterize an indeterminate renal mass were analyzed from 6 community (median: 17 reports/site) and 6 academic (median: 23 reports/site) United States practices. Report contents were compared to a published national survey of stated preferences by academic radiologists and urologists from 9 institutions. Descriptive statistics and Chi-square tests were calculated. Of 319 reports, 85% (271; 192 CT, 79 MRI) reported a possibly malignant mass (236 solid, 35 cystic). Some essential elements were commonly described: size (99% [269/271]), mass type (solid vs. cystic; 99% [268/271]), enhancement (presence vs. absence; 92% [248/271]). Other essential elements had incomplete penetrance: the presence or absence of fat in solid masses (14% [34/236]), size comparisons when available (79% [111/140]), Bosniak classification for cystic masses (54% [19/35]). Preferred but non-essential elements generally were described in less than half of reports. Nephrometry scores usually were not included for local therapy candidates (12% [30/257]). Academic practices were significantly more likely than community practices to include mass characterization details, probability of malignancy, and staging. Community practices were significantly more likely to include management recommendations. Renal mass reporting elements considered essential or preferred often are omitted in radiology reports. Variation exists across radiologists and practice settings. A standardized template may mitigate these inconsistencies.

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.

Our study aims evaluation of level of essential trace elements and heavy metals in the hair samples of children with autistic spectrum disorder (ASD) and identification of changes that are associated with autistic spectrum disorders. Case-control study was conducted at Child Development Center of Iashvili Children's Central Hospital (LD).We studied 60 children aged from 4 to 5 years old. The concentrations of 28 elements among (Ca,Zn, K, Fe, Cu, Se, Mn, Cr, S, Br, Cl, Co, Ag, V, Ni, Rb, Mo, Sr, Ti, Ba, Pb, As, Hg, Cd, Sb, Zr, Sn, Bi) them trace elements and toxic metals) were determined in scalp hair samples of children (n=30) with autistic spectrum disorder (ASD) and from control group of healthy children (n=30) with matched sex and age. Micro-elemental status was detected in the hair, with roentgen-fluorescence spectrometer method (Method MBИ 081/12-4502-000, Apparatus ALVAX- CIP, USA - UKRAIN) .To achieve the similarity of study and control groups, pre and postnatal as well as family and social history were assessed and similar groups were selected. Children with genetic problems, malnourished children, children from families with social problems were excluded from the study. The diagnosis of ASD were performed by pediatrician and psychologist (using M-CHAT and ADOS) according to DSM IV (Diagnostic and Statistical Manual of Mental Disorders from the American Psychiatric association) criteria. The study was statistically analyzed using computer program SPSS 19. Deficiencies of essential trace microelements revealed in both group, but there was significant difference between control and studied groups. The most deficient element was zinc (92% in target and 20% in control), then - manganese (55% and 8%) and selenium (38% and 4%). In case of cooper study revealed excess concentration of this element only in target group in 50% of cases. The contaminations to heavy metals were detected in case of lead (78% and 16), mercury (43% and 10%) and cadmium (38% and 8%). The study statistical results indicated, that deficient concentrations of trace elements such as zinc, manganese, molybdenum and selenium in hair significantly linked with ASD (Kramer's V was 0,740; 0,537; 0,333; 0,417 accordingly). In case of cooper we got excess levels of this element and this data was highly linked with autism spectrum disorder. We got high associations and significant values between of lead, mercury and cadmium concentrations and ASD. Study results indicate that there are significant differences of hair essential trace elements concentrations in children with autism spectrum disorder comparing with healthy children group. The result obtained also showed high contamination to heavy metals such as lead, mercury and cadmium in ASD children compared to healthy ones. So, our study demonstrated alteration in levels of toxic heavy metals and essential trace elements in children with autistic spectrum disorders as compared to healthy children. This suggests a possible pathophysiological role of heavy metals and trace elements in the genesis of symptoms of autism spectrum disorders.

To analyze the literature as regards the knowledge, skills and attitudes that these disciplines can provide in improving technical, ethical and human quality health care in the elderly with advanced organ failure, multimorbidity, frailty and progressive dementia. A comprehensive review focused on available references on the interrelationship between geriatric medicine and palliative medicine, education in bioethics, prognostic tools, functional status, and the humanization of health care. Advance care planning, comprehensive geriatric assessment, the study of the values of the patient and their introduction in decision-making process, as well as the need to promote moral, care, and healthcare organizational ethics, are essential elements to achieve this objective. Practitioners and healthcare organizations should seek excellence as a moral requirement. To achieve this, there is a priority to acquire virtues of care and fundamental concepts of geriatric and palliative medicine, assessing functional status, advance care planning and patient/family needs as essential issues to protect, care for and promote them in all care settings.

Early in their careers, many new surgeons lack the background and experience to understand essential components needed to build a surgical practice. Surgical resident education is often devoid of specific instruction on the business of medicine and practice management. In particular, hepatobiliary and pancreatic (HPB) surgeons require many key components to build a successful practice secondary to significant interdisciplinary coordination and a scope of complex surgery, which spans challenging benign and malignant disease processes. In the following, we describe the required clinical and financial components for developing a successful HPB surgery practice in the nonuniversity tertiary care center. We discuss significant financial considerations for understanding community need and hospital investment, contract establishment, billing, and coding. We summarize the structural elements and key personnel necessary for establishing an effectual HPB surgical team. This article provides useful, essential information for a new HPB surgeon looking to establish a surgical practice. It also provides insight for health-care administrators as to the value an HPB surgeon can bring to a hospital or health-care system.

The first aim of the study was to evaluate calculated dietary intake and concentrations measured in blood or urine of essential and toxic elements in relation to nutritional and toxicological reference values. The second aim was to identify patterns of the element concentrations in blood and urine and to identify possible dietary determinants of the concentrations of these elements. Adults with a known high consumption of environmental contaminants (n=111), and a random sample of controls (n=76) answered a validated food frequency questionnaire (FFQ). Complete data on biological measures were available for 179 individuals. Blood and urine samples were analyzed for selenium, iodine, arsenic, mercury, cadmium and lead. Principal component analysis was used to identify underlying patterns of correlated blood and urine concentrations. The calculated intakes of selenium, iodine, inorganic arsenic and mercury were within guideline levels. For cadmium 24% of the high consumer group and 8% of the control group had intakes above the tolerable weekly intake. Concentrations of lead in blood exceeded the bench-mark dose lower confidence limits for some participants. However, overall, the examined exposures did not give rise to nutritional or toxicological concerns. Game consumption was associated with lead in blood (B(ln) 0.021; 95%CI:0.010, 0.031) and wine consumption. Seafood consumption was associated with urinary cadmium in non-smokers (B(ln) 0.009; 95%CI:0.003, 0.015). A novel finding was a distinct pattern of positively associated biological markers, comprising iodine, selenium, arsenic and mercury (eigenvalue 3.8), reflecting seafood intake (B 0.007; 95%CI:0.004, 0.010). The study clearly demonstrates the significance of seafood as a source of both essential nutrients and toxic elements simultaneously and shows that exposure to various essential and toxic elements can be intertwined. © 2013 Elsevier B.V.

The present study investigated the essential and non-essential elements in cultivated and wild mussels and assessed the health risk arising from their consumption as an impact of rapid growth and intensive production of Mytilus galloprovincialis in the mussel farms of the Boka Kotorska Bay. The concentrations of macro, micro, nonessential and even the small amounts of potentially toxic elements in the cultivated and wild mussels were influenced by industry, tourism and the geohydrology of the Bay. In the case of cultivated mussels, the limiting factor, i.e., the element the elevated concentration of which restricts mussels consumption, was Zr, while in the case of wild mussels the limiting factors were Cr and As. The sites with cultivated mussels stand out as sites with the highest calculated element pollution index, the total hazard index and with higher estimated risk to the health of consumers.

There is a compelling evidence in support of negative associations between essential trace and toxic elements in different types of cancer. The aim of the present study was to investigate the relationship between carcinogenic (As, Cd, Ni) and anti-carcinogenic (Se, Zn) trace elements in scalp hair samples of different male cancerous patients (esophagus, lung, mouth, and urinary bladder). For comparative purposes, the scalp hair samples of healthy males of the same age group (ranged 35-65 years) as controls were analyzed. Both controls and patients have the same socioeconomic status, localities, dietary habits, and smoking locally made cigarette. The scalp hair samples were oxidized by 65% nitric acid: 30% hydrogen peroxide (2:1) ratio in microwave oven followed by atomic absorption spectrometry. The validity and accuracy of the methodology were checked using certified reference material of human hair BCR 397. The mean concentrations of As, Cd, and Ni were found to be significantly higher in scalp hair samples of patients having different cancers as compared to the controls, while reverse results were obtained in the case of Se and Zn levels (p < 0.01). The study revealed that the carcinogenic processes are significantly affecting the trace elements burden and mutual interaction of essential trace and toxic elements in the cancerous patients.

The essentiality of 14 mineral elements so far have been reported in plant nutrition. Eight of these elements were known as micronutrients due to their lower concentrations in plants (usually ≤100 mg/kg/dw). However, it is still challenging to mention an exact number of plant micronutrients since some elements have not been strictly proposed yet either as essential or beneficial. Micronutrients participate in very diverse metabolic processes, including from the primary and secondary metabolism to the cell defense, and from the signal transduction to the gene regulation, energy metabolism, and hormone perception. Thus, the attempt to understand the molecular mechanism(s) behind their transport has great importance in terms of basic and applied plant sciences. Moreover, their deficiency or toxicity also caused serious disease symptoms in plants, even plant destruction if not treated, and many people around the world suffer from the plant-based dietary deficiencies or metal toxicities. In this sense, shedding some light on this issue, the 13 mineral elements (Fe, B, Cu, Mn, Mo, Si, Zn, Ni, Cl, Se, Na, Al, and Co), required by plants at trace amounts, has been reviewed with the primary focus on the transport proteins (transporters/channels) in plant roots. So, providing the compiled but extensive information about the structural and functional roles of micronutrient transport genes/proteins in plant roots.

Humanistic nursing practice which is dominated by technological advancement, outcome measurement, reduced resources, and staff shortages is challenging in the present work environment. To examine the main concern in humanistic nursing area and how the way it is solved and resolved by Iranian nurses in acute care setting. Data were collected from interviews and observations in 2009-2011 and analyzed using classic grounded theory. Memos were written during the analysis, and they were sorted once theoretical saturation occurred. Participants and research context: In total, 22 nurses, 18 patients, and 12 families from two teaching hospitals in Tehran were selected by purposeful and theoretical sampling. Ethical considerations: The research was approved by the Ethics Committee of the university and hospitals. The main concern for the nurses is the violation of their rights. They overcome this concern when there is a synergy of situation-education/learning, that is, a positive interaction between education and learning of values and sensitivity of the situation or existence of care promotion elements. They turn to professional values and seeking and meeting others' needs, resulting in "success and accomplishment" of nurse/nursing manager and patient/family. This theory shows that professional values, elements of care promotion, and sensitivity of the situation have a key role in activation of humanistic approach in nursing. Violation of the nurses' professional rights often leads to a decrease in care, but these factors make the nurses practice in an unsparing response approach. It is necessary to focus on development of professional values and provide essential elements of care promotion as changeable factors for realization of humanistic nursing although there is a context in which the nurses' rights are violated.

To describe the Green House (GH) model of nursing home (NH) care, and examine how GH homes vary from the model, one another, and their founding (or legacy) NH. Data include primary quantitative and qualitative data and secondary quantitative data, derived from 12 GH/legacy NH organizations February 2012-September 2014. This mixed methods, cross-sectional study used structured interviews to obtain information about presence of, and variation in, GH-relevant structures and processes of care. Qualitative questions explored reasons for variation in model implementation. Interview data were analyzed using related-sample tests, and qualitative data were iteratively analyzed using a directed content approach. GH homes showed substantial variation in practices to support resident choice and decision making; neither GH nor legacy homes provided complete choice, and all GH homes excluded residents from some key decisions. GH homes were most consistent with the model and one another in elements to create a real home, such as private rooms and baths and open kitchens, and in staff-related elements, such as self-managed work teams and consistent, universal workers. Although variation in model implementation complicates evaluation, if expansion is to continue, it is essential to examine GH elements and their outcomes. © Health Research and Educational Trust.

Minerals such as zinc, copper, selenium, calcium, and magnesium are essential for normal human development and functioning of the body. They have been found to play important roles in immuno-physiologic functions. The study is to evaluate the distribution and correlation of nonessential (lead) and essential elements in whole blood from 1- to 72-month old children. The cross-sectional study was performed in 1551 children. Six element concentrations, including copper (Cu), zinc (Zn), calcium (Ca), magnesium (Mg), iron (Fe) and lead (Pb) in the blood were determined by atomic absorption spectrometry. Distributions and correlations of trace elements in different age groups were analyzed and compared. A Pearson correlation controlled for age and gender was used to assess the relationship of non essential (lead) and essential elements. Levels of copper and magnesium were 18.09 ± 4.42 µmol/L and 1.42 ± 0.12 mmol/L, respectively. 6.04% of all children showed copper levels below the normal threshold, the levels of Magnesium were stable in different age groups. Though the overall mean blood zinc and iron concentrations (61.19 ± 11.30 µmol/L and 8.24 ± 0.59 mmol/L, respectively) gradually increased with age and the overall deficiency levels (24.1% and 36.0%, respectively) decreased with age, zinc and iron deficiencies were still very stable. Controlling for gender and age, significant positive correlations were found when comparing copper to zinc, calcium, magnesium, and iron ((r = 0.333, 0.241, 0.417, 0.314 ,p < 0.01); zinc to magnesium and iron (r = 0.440, 0.497p < 0.01); and magnesium to Calcium and iron (r = 0.349, 0.645, p < 0.01). The overall mean blood lead levels (41.16 ± 16.10) were relatively unstable among different age groups. The prevalence of lead intoxication in all children was 1.3% .Calcium levels decreased gradually with age, with an overall concentration of 1.78 ± 0.13 mmol/L. Significant negative correlations were also noted between Pb and Zn, Fe (r = -0.179, -0.124.p < 0.01) .The importance of calcium deficiency and supplementation is well realized, but the severity of iron and zinc deficiency is not well recorded. The degree of lead intoxication in all the children studied was low; The established reference intervals for Cu, Zn, Ca and Mg provide an important guidance for the reasonable supplementation of essential elements during different age groups.

Against a paucity of evidence, a model describing elements of health governance best suited to achieving integrated care internationally was developed. The aim of this study was to explore how health meso-level organisations used, or planned to use, the governance elements. A case study design was used to offer two contrasting contexts of health governance. Semi-structured interviews were conducted with participants who held senior governance roles. Data were thematically analysed to identify if the elements of health governance were being used, or intended to be in the future. While all participants agreed that the ten elements were essential to developing future integrated care, most were not used. Three major themes were identified: (1) organisational versus system focus, (2) leadership and culture, and, (3) community (dis)engagement. Several barriers and enablers to the use of the elements were identified and would require addressing in order to make evidence-based changes. Despite a clear international policy direction in support of integrated care this study identified a number of significant barriers to its implementation. The study reconfirmed that a focus on all ten elements of health governance is essential to achieve integrated care.

To identify the perceived level of competence in teaching and assessing critical thinking skills and the difficulties facing radiologic science program directors in implementing student-centered teaching methods. A total of 692 program directors received an invitation to complete an electronic survey soliciting information regarding the importance of critical thinking skills, their confidence in applying teaching methods and assessing student performance, and perceived obstacles. Statistical analysis included descriptive data, correlation coefficients, and ANOVA. Responses were received from 317 participants indicating program directors perceive critical thinking to be an essential element in the education of the student; however, they identified several areas for improvement. A high correlation was identified between the program directors' perceived level of skill and their confidence in critical thinking, and between their perceived level of skill and ability to assess the students' critical thinking. Key barriers to implementing critical thinking teaching strategies were identified. Program directors value the importance of implementing critical thinking teaching methods and perceive a need for professional development in critical thinking educational methods. Regardless of the type of educational institution in which the academic program is located, the level of education held by the program director was a significant factor regarding perceived confidence in the ability to model critical thinking skills and the ability to assess student critical thinking skills.

Disability, gender, and employment relationships in Africa: The case of Ghana

The exploratory quantitative study sought to develop an understanding about the relationships among disability, gender and employment in Northern Ghana. A total of 110 individuals with disabilities (20–60 years) from various disability groups participated in the study. The results indicate that many persons with disabilities are unemployed, the majority being women. Discrimination is cited as the greatest barrier to the employment of persons with disabilities, particularly women. The majority of persons with disabilities, typically women, live in poverty; given that some are unemployed and those who are employed worked mostly in marginal, seasonal and menial jobs. Persons with disabilities also experience several challenges on the job, including negative perceptions about their capabilities, discrimination and exclusion, irrespective of the employment sector and disability type. Educational interventions such as workshops, documenting and showcasing success stories of persons with disabilities could be helpful to reduce negative perceptions about their capabilities as well as discrimination against them. Government intervention to support persons with disabilities with start-up capital and funding for formal education is also recommended as these two elements were identified respectively as barriers to self-employment and employment in the public/private sectors. Government interventions to create educational opportunities for persons with disabilities are essential given that lower educational attainment affect their employment. PMID:28730017

SilMush: A procedure for modeling of the geochemical evolution of silicic magmas and granitic rocks

NASA Astrophysics Data System (ADS)

Hertogen, Jan; Mareels, Joyce

2016-07-01

A boundary layer crystallization modeling program is presented that specifically addresses the chemical fractionation in silicic magma systems and the solidification of plutonic bodies. The model is a Langmuir (1989) type approach and does not invoke crystal settling in high-viscosity silicic melts. The primary aim is to model a granitic rock as a congealed crystal-liquid mush, and to integrate major element and trace element modeling. The procedure allows for some exploratory investigation of the exsolution of H2O-fluids and of the fluid/melt partitioning of trace elements. The procedure is implemented as a collection of subroutines for the MS Excel spreadsheet environment and is coded in the Visual Basic for Applications (VBA) language. To increase the flexibility of the modeling, the procedure is based on discrete numeric process simulation rather than on solution of continuous differential equations. The program is applied to a study of the geochemical variation within and among three granitic units (Senones, Natzwiller, Kagenfels) from the Variscan Northern Vosges Massif, France. The three units cover the compositional range from monzogranite, over syenogranite to alkali-feldspar granite. An extensive set of new major element and trace element data is presented. Special attention is paid to the essential role of accessory minerals in the fractionation of the Rare Earth Elements. The crystallization model is able to reproduce the essential major and trace element variation trends in the data sets of the three separate granitic plutons. The Kagenfels alkali-feldspar leucogranite couples very limited variation in major element composition to a considerable and complex variation of trace elements. The modeling results can serve as a guide for the reconstruction of the emplacement sequence of petrographically distinct units. Although the modeling procedure essentially deals with geochemical fractionation within a single pluton, the modeling results bring up a number of questions about the petrogenetic relationships among parental magmas of nearly coeval granitic units emplaced in close proximity.

The mineral composition of target and non-target pelagic fish caught by purse-seiners and longliners in the western-central Indian Ocean was determined. From the 10 essential elements analysed, selenium and zinc showed the highest concentrations in swordfish and blue marlin while Indian mackerel appeared as a good source of copper, iron and chrome. All catch had levels of lead and cadmium, two toxic elements, below the maximum sanitary limits. Although some concerns were raised regarding mercury concentrations in the largest species (wahoo, swordfish and blue marlin), molar ratios of mercury and selenium indicate that all oceanic pelagic fish from the western-central Indian Ocean are safe for human consumption. This study also gives insights on the relationships between the levels of essential and toxic elements in fish muscle and the size, trophic position and diet sources of the studied pelagic species.

Against all odds: Tales of survival and growth of the Foundational Approaches in Science Teaching (FAST) project

NASA Astrophysics Data System (ADS)

Yamamoto, Karen Kina

This study examines the dynamics of survival and growth of curricular and instructional innovations. It focuses on the Foundational Approaches in Science Teaching (FAST) project, a long-term survivor of reform in science education. Key questions guiding this study include: (1) How did the FAST project survive over the past 30 years? (2) What elements are essential for long-term survival and growth of an innovative science program? (3) Why did the project continue to survive amidst several waves of educational reform? The core of my conceptual framework is that the odds of survival and growth of curricular and instructional innovations are increased by the extent to which resources, theory-based curriculum development processes, and professional development strategies are not only incorporated into but also interdependent within a project. With this framework as a guide, the main methods of data collection were document analysis, interviews, and observations. FAST, developed by the University of Hawaii's Curriculum Research and Development Group (CRDG), consists of a sequential and interdisciplinary middle and high school science program for students in grades 6-10. According to the results of this study, the project was able to survive by receiving constant organizational support from CRDG and a steady source of State funding through the university since 1966; it also retained a relatively small but stable staff of highly qualified project personnel. Formulated on a discipline-based theory that values development of students' intellectual capacities as the platform for curriculum research, design, and development, the FAST project translated this vision of science education into key elements of an innovative program that survived and thrived: (1) an interdisciplinary program consisting of physical, biological, and earth sciences; inquiry as content and process; history and philosophy of science; and links between and among sciences, technology, and society; and (2) teaching and learning strategies that model a community of practicing scientists. This study also identified the main elements of professional development strategies essential for an innovative project's survival and growth: linking curriculum development to required pre-implementation inservice training, engaging project personnel in both of these phases recruiting, training a cadre of experienced FAST teachers as inservice trainers, and providing follow-up professional development seminars. In conclusion, the FAST project survived mainly because the longevity of its leaders gave stability and continuity to the project. Against many odds such as limited financial resources and a small number of staff positions relative to the project's scope, the leaders managed with whatever resources were available to link theory-based curriculum development with professional development and, thereby, increase the project's chances for survival and growth.

To describe the process and challenges from a project that aimed to develop processes, source new placements and place students primarily in the discipline of nursing, but also occupational therapy, physiotherapy, podiatry, social work, and speech therapy. Clinical experience in health facilities is an essential element of health professional education, yet globally, there is a lack of clinical placements to meet demands. Educational providers are seeking placements in nontraditional facilities, yet little has been reported on the challenges in the process of procuring clinical placements. The project used a descriptive approach within a quality implementation framework. The project was guided by the quality implementation framework that included four critical steps: considerations of the host setting, structuring the implementation, supporting the implementation and improving future applications. A total of 115 new student placements were finalised across six health disciplines, including elderly care, nongovernment organisations and general practice. Sixty-two nursing students were placed in the new placements during the project. Challenges included communication, the time-consuming nature of the process and 'gatekeeping' blocks to obtaining placements. Recommendations included the importance of personal interaction in developing and maintaining relationships, and the need for clear communication processes and documentation. Potential areas for research are also given. There is great potential for growth in establishing new placements outside the traditional placement facilities for nursing and allied health and for expanding already existing nonhospital placements. Clinical professional experiences are essential to any nursing or allied health programme. There is an increasing demand for, and global lack of, clinical placements for nursing and allied health students. The results provide nursing and allied health educators and managers a framework for planning clinical placement procurement, and assisting in decision-making and developing strategies and processes for practice. © 2016 John Wiley & Sons Ltd.

Background Care for patients with chronic diseases is a challenge after a disaster. This is particularly true for individuals from health disparate populations as they are less likely to evacuate, have less financial resources and often depend on resource-strapped institutions for their care. The specific aim of the study presented here was to elicit challenges and solutions in the provision of health care to those with chronic diseases after Hurricane Katrina in coastal Alabama and Mississippi. Methods Focusing on agencies providing care to health disparate populations, a qualitative methodology was employed using in-depth interviews with health and social service providers. Participants identified key elements essential to disaster preparedness. Results Pre-disaster issues were patient education and preparedness, evacuation, special needs shelters and health care provider preparedness. Post-disaster issues were communication, volunteer coordination and donation management. Conclusions Lessons learned from those on the ground administering healthcare during disasters should inform future disaster preparations. Furthermore, the methodological approach used in this study engendered collaboration between healthcare institutions and may enhance future inter-agency disaster preparedness. PMID:18703906

The VR-1 training reactor operated by the Czech Technical University in Prague is utilized mainly for education of students and training of various reactor staff; however, R&D is also carried out at the reactor. The experimental instrumentation of the reactor can be used for the irradiation experiments and neutron activation analysis. In this paper, the neutron activation analysis (NAA) is used for a study of dietary supplements containing the zinc (one of the essential trace elements for the human body). This analysis includes the dietary supplement pills of different brands; each brand is represented by several different batches of pills. All pills were irradiated together with the standard activation etalons in the vertical channel of the VR-1 reactor at the nominal power (80 W). Activated samples were investigated by the nuclear gamma-ray spectrometry technique employing the semiconductor HPGe detector. From resulting saturated activities, the amount of mineral element (Zn) in the pills was determined using the comparative NAA method. The results show clearly that the VR-1 training reactor is utilizable for neutron activation analysis experiments.

Best-practices pedagogy in science, technology, engineering, and mathematics (STEM) aims for inclusive excellence that fosters student persistence. This paper describes principles of inclusivity across 11 primarily undergraduate institutions designated as Capstone Awardees in Howard Hughes Medical Institute’s (HHMI) 2012 competition. The Capstones represent a range of institutional missions, student profiles, and geographical locations. Each successfully directed activities toward persistence of STEM students, especially those from traditionally underrepresented groups, through a set of common elements: mentoring programs to build community; research experiences to strengthen scientific skill/identity; attention to quantitative skills; and outreach/bridge programs to broaden the student pool. This paper grounds these program elements in learning theory, emphasizing their essential principles with examples of how they were implemented within institutional contexts. We also describe common assessment approaches that in many cases informed programming and created traction for stakeholder buy-in. The lessons learned from our shared experiences in pursuit of inclusive excellence, including the resources housed on our companion website, can inform others’ efforts to increase access to and persistence in STEM in higher education.

Many trace heavy elements are carcinogenic and increase the incidence of cancer. However, a comprehensive study of the correlation between multiple trace elements and DNA oxidative damage is still lacking. The aim of this study is to investigate the relationships between the body burden of multiple trace elements and DNA oxidative stress in college students in Guangzhou, China. Seventeen trace elements in urine samples were determined by inductively coupled plasma-mass spectrometry (ICP-MS). Urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of DNA oxidative stress, was also measured using liquid chromatography tandem mass spectrometer (LC-MS/MS). The concentrations of six essential elements including manganese (Mn), copper (Cu), nickel (Ni), selenium (Se), strontium (Sr), and molybdenum (Mo), and five non-essential elements including arsenic (As), cadmium (Cd), aluminum (Al), stibium (Sb), and thallium (Tl), were found to be significantly correlated with urinary 8-OHdG levels. Moreover, urinary levels of Ni, Se, Mo, As, Sr, and Tl were strongly significantly correlated with 8-OHdG (P < 0.01) concentration. Environmental exposure and dietary intake of these trace elements may play important roles in DNA oxidative damage in the population of Guangzhou, China.

Energy Literacy: A Natural and Essential Part of a Solutions-Based Approach to Climate Literacy

As with climate science topics, many Americans have misconceptions or gaps in understanding related to energy topics. Recent literacy efforts are geared to address these gaps in understanding. The U.S. Global Change Research Program's recently published "Energy Literacy: Essential Principles and Fundamental Concepts for Energy Education" offers a welcome complement to the Climate Literacy Essential Principles released in 2008. Research and experience suggest that education, communication and outreach about global climate change and related topics is best done using a solutions-based approach. Energy is a natural and effective topic to frame these solutions around. Used as a framework for designing curricula, Energy Literacy naturally leads to solutions-based approaches to Climate Change education. An inherently interdisciplinary topic, energy education must happen in the context of both the natural and social sciences. The Energy Literacy Essential Principles reflect this and open the door to curriculum that integrates the two.

Writing for publication, in the nursing profession, is considered essential for the development of the profession and individual career advancement. In education there is also the increasing pressure to produce University research output. To develop a collaborative writing group to develop and write articles relating to our teaching practice. The idea of forming a writing group was discussed at a module team meeting where five academics expressed an interest. The process of forming the group involved an initial meeting to discuss and agree to the aims, interests, expertise and areas of responsibility for each member. Regular meetings are held and each member takes on responsibility for an aspect of work towards completing the articles. Three articles and one editorial have been published and another is under peer review. We have endeavoured to develop and maintain a theme, this being supporting nursing students' development with an emphasis on an aspect of their decision making skills. Also, importantly, we have created a supportive environment and friendships. The demands made upon the nurse educator to be clinically, educationally and research active can be difficult to meet. Collaborative writing groups may be one way to fulfil the scholarly activity element. Copyright © 2013 Elsevier Ltd. All rights reserved.

2004-01-01

Palliative home care is an important component of the care system for patients at the end of life and case management is considered an essential element of the Canadian home care system. Case managers play a critical role in allocating resources, thus influencing the costs and the viability of palliative home care. Case management education programs focused on care coordination with specialty palliative care populations are nonexistent. An education program targeted at improving the knowledge and skills of case managers in allocating resources to palliative care populations was developed and pilot-tested in a metropolitan Canadian city home care program. Core curriculum was based on an initial learning needs assessment and used case-based problem solving to enhance case-management skills. An improvement in knowledge was noted on posttests and case managers described increased comfort and confidence in their role as case managers to this patient population. Home care organizations caring for palliative care populations must ensure case managers are prepared for case management roles with specialty populations if the home is to be rendered an appropriate and viable care setting for patients at the end of life.

Abstract Sex, a biological variable, and gender, a cultural variable, define the individual and affect all aspects of disease prevention, development, diagnosis, progression, and treatment. Sex and gender are essential elements of individualized medicine. However, medical education rarely considers such topics beyond the physiology of reproduction. To reduce health care disparities and to provide optimal, cost-effective medical care for individuals, concepts of sex and gender health need to become embedded into education and training of health professionals. In September 2012, Mayo Clinic hosted a 2-day workshop bringing together leading experts from 13 U.S. schools of medicine and schools of public health, Health Resources and Services Administration Office of Women's Health (HRSA OWH), the National Institutes of Health (NIH) Office of Research on Women's Health (ORWH), and the Canadian Institute of Health and Gender. The purpose of this workshop was to articulate the need to integrate sex- and gender-based content into medical education and training, to identify gaps in current medical curricula, to consider strategies to embed concepts of sex and gender health into health professional curricula, and to identify existing resources to facilitate and implement change. This report summarizes these proceedings, recommendations, and action items from the workshop. PMID:23414074

The role of trace metals elements in human nutrition can no longer be ignored. Deficiency caused by inadequate dietary intake, secondary deficiencies often under - estimated, and iatrogenic deficiencies lead to pathologies such as infections and others. For this reason their dosages are particularly important to assess disease severity and to facilitate early treatment or improve patient's diet. The aim of this study was to determine trace elements profile in blood (copper, selenium, zinc, iron, chromium, cobalt, etc.) among malnourished and well-nourished children in a mining community in Lubumbashi. Three hundred eleven cases have been collected, 182 malnourished children and 129 well-nourished children in a cross-sectional descriptive study conducted from July 2013 to December 2014. Exhaustive sampling was performed. Metal determination in serum was performed using Inductively Coupled Plasma Spectroscopy (ICP-OES/MS) in the laboratory at Congolese Control Office in Lubumbashi. Essential trace elements (copper, zinc, selenium and iron) were found at very low concentrations in both the malnourished and well-nourished children. Arsenic, cadmium, magnesium and manganese concentrations were normal compared with reference values in well-nourished children Antimony, chromium, lead and cobalt levels were high in both the malnourished and well-nourished children. Nickel level was normal malnourished and well-nourished children. Magnesium, manganese were found in very low levels in malnourished children. Both the malnourished and well-nourished children suffer from deficiencies of essential trace elements associated with trace metals elements This allows to assume that essential micronutrients deficiency promotes the absorption of heavy metals.

To understand the perspectives of people with type 1 diabetes with regards to the diabetes education they receive within the health system. Grounded Theory was used for the collection and analysis of data from interviews with 101 people with type 1 diabetes from 13 countries. There are two aspects to education, namely initial education received when diagnosed and the ongoing education people continue to receive. Within these two categories content and process of diabetes education are important as are factors linked to the healthcare worker and setting. Tangible elements are the "what" that is delivered and are the different skills and information needed for people to manage their diabetes. Process elements are the "how" this is delivered. Finally intangible elements are those, which were found to be specific to certain contexts and health professionals. These could be the hardest to replicate, but possibly the most important. Health systems can provide the tangible elements and organize themselves to have processes in place to deliver education. The challenge is how can the intangible elements be seen as important and developed and delivered to improve management, but also meet the needs of people with diabetes.

Singh, Kavita; Story, William T; Moran, Allisyn C

2016-02-01

We assess how countries in regions of the world where maternal mortality is highest-South Asia and Sub-Saharan Africa-are performing with regards to providing women with vital elements of the continuum of care. Using recent Demographic and Health Survey data from nine countries including 18,036 women, descriptive and multilevel regression analyses were conducted on four key elements of the continuum of care-at least one antenatal care visit, four or more antenatal care visits, delivery with a skilled birth attendant and postnatal checks for the mother within the first 24 h since birth. Family planning counseling within a year of birth was also included in the descriptive analyses. Results indicated that a major drop-out (>50 %) occurs early on in the continuum of care between the first antenatal care visit and four or more antenatal care visits. Few women (<5 %) who do not receive any antenatal care go on to have a skilled delivery or receive postnatal care. Women who receive some or all the elements of the continuum of care have greater autonomy and are richer and more educated than women who receive none of the elements. Understanding where drop-out occurs and who drops out can enable countries to better target interventions. Four or more ANC visits plays a pivotal role within the continuum of care and warrants more programmatic attention. Strategies to ensure that vital services are available to all women are essential in efforts to improve maternal health.

Trace elements in Mediterranean seagrasses and macroalgae. A review.

This review investigates the current state of knowledge on the levels of the main essential and non-essential trace elements in Mediterranean vascular plants and macroalgae. The research focuses also on the so far known effects of high element concentrations on these marine organisms. The possible use of plants and algae as bioindicators of marine pollution is discussed as well. The presence of trace elements is overall well known in all five Mediterranean vascular plants, whereas current studies investigated element concentrations in only c. 5.0% of all native Mediterranean macroalgae. Although seagrasses and macroalgae can generally accumulate and tolerate high concentrations of trace elements, phytotoxic levels are still not clearly identified for both groups of organisms. Moreover, although the high accumulation of trace elements in seagrasses and macroalgae is considered as a significant risk for the associated food webs, the real magnitude of this risk has not been adequately investigated yet. The current research provides enough scientific evidence that seagrasses and macroalgae may act as effective bioindicators, especially the former for trace elements in sediments, and the latter in seawater. The combined use of seagrasses and macroalgae as bioindicators still lacks validated protocols, whose application should be strongly encouraged to biomonitor exhaustively the presence of trace elements in the abiotic and biotic components of coastal ecosystems.

The Autographa californica Multiple Nucleopolyhedrovirus ac83 Gene Contains a cis-Acting Element That Is Essential for Nucleocapsid Assembly.

Baculoviridae is a family of insect-specific viruses that have a circular double-stranded DNA genome packaged within a rod-shaped capsid. The mechanism of baculovirus nucleocapsid assembly remains unclear. Previous studies have shown that deletion of the ac83 gene of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) blocks viral nucleocapsid assembly. Interestingly, the ac83 -encoded protein Ac83 is not a component of the nucleocapsid, implying a particular role for ac83 in nucleocapsid assembly that may be independent of its protein product. To examine this possibility, Ac83 synthesis was disrupted by insertion of a chloramphenicol resistance gene into its coding sequence or by deleting its promoter and translation start codon. Both mutants produced progeny viruses normally, indicating that the Ac83 protein is not required for nucleocapsid assembly. Subsequently, complementation assays showed that the production of progeny viruses required the presence of ac83 in the AcMNPV genome instead of its presence in trans Therefore, we reasoned that ac83 is involved in nucleocapsid assembly via an internal cis -acting element, which we named the nucleocapsid assembly-essential element (NAE). The NAE was identified to lie within nucleotides 1651 to 1850 of ac83 and had 8 conserved A/T-rich regions. Sequences homologous to the NAE were found only in alphabaculoviruses and have a conserved positional relationship with another essential cis -acting element that was recently identified. The identification of the NAE may help to connect the data of viral cis -acting elements and related proteins in the baculovirus nucleocapsid assembly, which is important for elucidating DNA-protein interaction events during this process. IMPORTANCE Virus nucleocapsid assembly usually requires specific cis -acting elements in the viral genome for various processes, such as the selection of the viral genome from the cellular nucleic acids, the cleavage of concatemeric viral genome replication intermediates, and the encapsidation of the viral genome into procapsids. In linear DNA viruses, such elements generally locate at the ends of the viral genome; however, most of these elements remain unidentified in circular DNA viruses (including baculovirus) due to their circular genomic conformation. Here, we identified a nucleocapsid assembly-essential element in the AcMNPV (the archetype of baculovirus) genome. This finding provides an important reference for studies of nucleocapsid assembly-related elements in baculoviruses and other circular DNA viruses. Moreover, as most of the previous studies of baculovirus nucleocapsid assembly have been focused on viral proteins, our study provides a novel entry point to investigate this mechanism via cis -acting elements in the viral genome.

Adrenal Crises in Children: Perspectives and Research Directions.

Rushworth, R Louise; Torpy, David J; Stratakis, Constantine A; Falhammar, Henrik

2018-06-06

Adrenal crises (AC) are life-threatening physiological disturbances that occur at a rate of 5-10/100 patient years in patients with adrenal insufficiency (AI). Despite their seriousness, there is a paucity of information on the epidemiology of AC events in the paediatric population specifically, as most investigations have focused on AI and ACs in adults. Improved surveillance of AC-related morbidity and mortality should improve the delineation of AC risk overall and among different subgroups of paediatric patients with AI. Valid incidence measures are essential for this purpose and also for the evaluation of interventions aimed at reducing adverse health outcomes from ACs. However, the absence of an agreed AC definition limits the potential benefit of research and surveillance in this area. While approaches to the treatment and prevention of ACs have much in common across the lifespan, there are important differences between children and adults with regards to the physiological, psychological, and social milieu in which these events occur. Education is considered to be an essential element of AC prevention but studies have shown that ACs occur even among well-educated patients, suggesting that new strategies may be needed. In this review, we examine the current knowledge regarding AC events in children with AI; assess the existing definitions of an AC and offer a new definition for use in research and the clinic; and suggest areas for further investigation that are aimed at reducing the incidence and health impact of ACs in the paediatric age group. © 2018 S.

Toward an essential ethic for teaching science in the new millennium

NASA Astrophysics Data System (ADS)

Hays, Irene De La Bretonne

The purpose of this study was to identify and explore values and views that might underlie an essential ethic for teaching science in the new millennium. With such an ethic, teachers may be better able to prepare young people to form and fully participate in communities that restore and sustain Earth. Reviewed in the literature for this study were changing philosophies and theories from early indigenous cultures to the present on the nature of nature, the value of nature, and the human relationship with nature. These philosophies and theories were found to influence values that today underlie the work scientists do and the ways young people are educated in science. In the study, two groups of participants--Nature Writers and scientists--revealed the essence and meaning of their relationship with nature. A two-stage, modified Delphi method was used for collecting data. Stage One comprised the first "round" of the Delphi and involved content analysis of writings by a select group of U.S. Nature Writers from the early 1800s to the present. In Stage Two, comprising three rounds of the modified Delphi, perspectives of Nature Writers were imbedded in questionnaires and presented for response to a select group of scientists connected with research and education at National Laboratories across the country. Finally, results from each participant group were brought together in a recursive process, one with the other, to determine findings. Strong Earth-care values, including receptivity, responsibility, interdependence, respect, cooperation, love, and care, were found to be held in common by the Nature Writers and scientists in this study and could form the foundation for an essential ethic for teaching science. The strongest dissonance between Nature Writers and scientists was evident in emotional and spiritual domains--despite that many scientists revealed emotional and spiritual elements in stories told of their experiences with nature. Contrary to what might have been expected from scientists based on theories of science and practices of science education represented in the literature, few scientists revealed negative, utilitarian, or dominionistic affiliations with nature. In contrast, no Nature Writers revealed such affiliations.

Background: Besides genetic factors, it is known that some trace elements, as Selenium, Copper, and Zinc are essential for thyroid gland fuction and thyroid hormone metabolism. Moreover, there were some metals effect that suggested patterns associated with overt thyroid disease. Aim of study: Hashimoto thyroiditis (HT), chronic autoimune inflamation of thyroid gland with cosequtive hipothyroidism, is common disease in Serbia, and we thought it is worthwile to explore potential effects of essential and toxic metals and metalloides on thyroid function and ability to restore euthyroid status of them. Results: This cross-sectional, case-control, study investigated the status of essential elements (Selenium,Copper,and Zinc) and toxic metals and metalloides (Al, Cr, Mn, Co, As, Cd, Sb, Ba, Be, Pb and Ni) from the blood of 22 female, patients with Hashimoto thyroiditis and overt hypothyroidism, and compared it with those of 55 female healthy persons. We tried to establish the presence of any correlation between previous mentioned elements and thyroid function in hypothyroid patients and healthy participants. Conclusions: The results of our study suggested that the blood concentration of essential trace elements, especially the ratio of Copper, and Selenium may influence directly thyroid function in patients with HT and overt hypothyroidism.Thus, our findings may have implication to life-long substitution therapy in terms of l-thyroxine dose reduction. Furthermore, for the first time, our study shown potential toxic effect of Cadmium on thyroid function in HT patients, which may implicate the dose of l-thyroxine substitution. © Georg Thieme Verlag KG Stuttgart · New York.

1) To identify the strengths and challenges of governance structures in academic emergency medicine (EM), and 2) to make recommendations on principles and approaches that may guide improvements. Over the course of 9 months, eight established EM leaders met by teleconference, reviewed the literature, and discussed their findings and experiences to arrive at recommendations on governance in academic units of EM. The results and recommendations were presented at the annual Canadian Association of Emergency Physicians (CAEP) Academic Symposium, where attendees provided feedback. The updated recommendations were subsequently distributed to the CAEP Academic Section for further input, and the final recommendations were decided by consensus. The panel identified four governance areas of interest: 1) the elements of governance; 2) the relationships between emergency physicians and academic units of EM, and between the academic units of EM and faculty of medicine; 3) current status of governance in Canadian academic units of EM; and 4) essential elements of good governance. Six recommendations were developed around three themes, including 1) the importance of good governance; 2) the purposes of an academic unit of EM; and 3) essential elements for better governance for academic units of EM. Recommendations included identifying the importance of good governance, recognizing the need to adapt to the different models depending on the local environment; seeking full departmental status, provided it is mutually beneficial to EM and the faculty of medicine (and health authority); using a consultation service to learn from the experience of other academic units of EM; and establishing an annual forum for EM leaders. Although governance of academic EM is complex, there are ways to iteratively improve the mission of academic units of EM: providing exceptional patient care through research and education. Although there is no one-size-fits-all guide, there are practical recommended steps for academic units of EM to consider.

2008-12-01

The National Center for Atmospheric Research (NCAR) has responded to the pressing need for professional development in climate and global change sciences by creating the Climate Discovery online course series. This series was designed with the secondary geoscience educator in mind. The online courses are based on current and credible climate change science. Interactive learning techniques are built into the online course designs with assignments that encourage active participation. A key element of the online courses is the creation of a virtual community of geoscience educators who exchange ideas related to classroom implementation, student assessment, and lessons plans. Geoscience educators from around the country have participated in the online courses. The ongoing interest from geoscience educators strongly suggests that the NCAR Climate Discovery online courses are a timely and needed professional development opportunity. The intent of NCAR Climate Discovery is to positively impact teachers' professional development scientifically authentic information, (2) experiencing guided practice in conducting activities and using ancillary resources in workshop venues, (3) gaining access to standards-aligned lesson plans, kits that promote hands-on learning, and scientific content that are easily implemented in their classrooms, and (4) becoming a part of a community of educators with whom they may continue to discuss the challenges of pedagogy and content comprehension in teaching climate change in the Earth system context. Three courses make up the Climate Discovery series: Introduction to Climate Change; Earth System Science - A Climate Change Perspective; and Understanding Climate Change Today. Each course, instructed by science education specialists, combines geoscience content, information about current climate research, hands-on activities, and group discussion. The online courses use the web-based Moodle courseware system (open- source software similar to Blackboard and webCT), utilizing its features to promote dialogue as well as provide rich online content and media. A key element of the online courses is the development and support of an online learning community, an essential component in successful online courses. Interactive learning techniques are built into the course designs with assignments that encourage active participation. Educators (both formal and informal) use the courses as a venue to exchange ideas and teaching resources. A unique feature of the courses is the emphasis on hands-on activities, a hallmark of our professional development efforts. This presentation will focus on the lessons learned in the development of the three online courses and our successful recruitment and retention efforts.

Identification of a distant cis-regulatory element controlling pharyngeal arch-specific expression of zebrafish gdf6a/radar

PubMed Central

Reed, Nykolaus P.; Mortlock, Douglas P.

2011-01-01

Skeletal formation is an essential and intricately regulated part of vertebrate development. Humans and mice deficient in Growth and Differentiation Factor 6 (Gdf6) have numerous skeletal abnormalities including joint fusions and cartilage reductions. The expression of Gdf6 is dynamic and in part regulated by distant evolutionarily conserved cis-regulatory elements. radar/gdf6a is a zebrafish ortholog of Gdf6 and has an essential role in embryonic patterning. Here we show that radar is transcribed in the cells surrounding and between the developing cartilages of the ventral pharyngeal arches, similar to mouse Gdf6. A 312 bp evolutionarily conserved region (ECR5), 122 kilobases downstream, drives expression in a pharyngeal arch-specific manner similar to endogenous radar/gdf6a. Deletion analysis identified a 78 bp region within ECR5 that is essential for transgene activity. This work illustrates that radar is regulated in the pharyngeal arches by a distant conserved element and suggests radar has similar functions in skeletal development in fish and mammals.

This paper presents a vision of humanoid robots as human's key partners in future space exploration, in particular for construction, maintenance/repair and operation of lunar/planetary habitats, bases and settlements. It integrates this vision with the recent plans, for human and robotic exploration, aligning a set of milestones for operational capability of humanoids with the schedule for the next decades and development spirals in the Project Constellation. These milestones relate to a set of incremental challenges, for the solving of which new humanoid technologies are needed. A system of systems integrative approach that would lead to readiness of cooperating humanoid crews is sketched. Robot fostering, training/education techniques, and improved cognitive/sensory/motor development techniques are considered essential elements for achieving intelligent humanoids. A pilot project in this direction is outlined.

2016-01-01

The development of empathy and positive attitudes are essential elements of professional education. This study explored the nature of empathy and its association with attitudes about, and exposure to older patients in a sample of dental students. Students completed an adapted version of the Jefferson Scale of Physician Empathy (JSPE), the Aging Semantic Differential (ASD) and answered questions about their exposure to older people. Factor analysis was used to identify four factors: (1) Empathy is Valuable, (2) Empathy is Demonstrated, (3) Empathy is not Influential, and (4) Empathy is Difficult to Accomplish. Higher empathy scores were related to the ASD subscale attitude of acceptability of aging and to greater exposure to older adults outside of clinical practice. There were no demographic predictors of higher empathy scores.

Regulation of ion homeostasis in plants: current approaches and future challenges.

Rouached, Hatem; Secco, David; Arpat, Bulak A

2010-05-01

The dependency of plants on essential macro- and micro-elements to complete their life cycle serves as a major entry point of these elements into the global food web. However, plants often face depletion of one or more essential elements limiting their growth. Thus, in modern agriculture, improving plant mineral nutrition has gained fundamental importance in order to address the issue of sustainable food resources for the growing world population. Heavy fertilization of soil was, for long time, chosen as a strategy to cope with the deficiency of these elements. Yet, this strategy is neither economically nor ecologically conceivable at long-term. As an alternative, genetic and breeding approaches that provide plants new characteristics enabling them to grow in nutrient-depleted soils, has become a major focal interest. The research emphasis so far has been on elucidating the molecular physiology of individual nutritive elements. However, in practice, application of such knowledge is hindered by complex cross-talks, which are emerging in the face of new data, between these elements. Developing integrative approaches, combining genetic, comparative genomics and 'omics' platforms, is crucial to untangle the interconnected signaling networks regulating ion homeostasis in plants.

In comparison with controls neutrophil granulocytes from Rheumatoid arthritis (RA), Infantile Neuronal Ceroid Lipofuscinosis (INCL), Chronic Lymphatic Leukemia (L) and Aplastic Anemia (AA) displayed significant alterations in essential and non-essential elements which might be interpreted as fingerprints of these deseases. The neutrophils from RA patients displayed alterations in the concentrations of iron, calcium, strontium, manganese, zinc and copper. INCL displayed alterations in the concentrations of iron and copper but in the INCL disease the iron concentration was about 2 times higher than in RA. In leukemia, aluminium was observed but not in the controls (< 0.5 μg/ g). The zinc concentration was lowered in leukemia. Aplastic anemia displayed alterations in zirconium, arsenic, molybdenum, iron and zinc. The platelets from RA, INCL, L and AA patients also displayed alterations in the elemental profiles. The platelets from AA patients displayed a unique elemental distribution of arsenic, zirconium and molybdenum. The elemental profiles of the thrombocytes and neutrophils might be used as a complement in the diagnosis of the examined diseases and in therapy the elemental profile might be used to monitor drugs at the cellular level.

Some trace elements are essential for newborns, their deficiency may cause abnormal biological functions, whereas excessive intakes due to environmental contamination may create adverse health effects. This study was conducted to measure the levels of selected trace elements in Chinese fish consumers by assessing their essentiality and toxicity via colostrum intake in newborns, and evaluated the effects of these trace elements on birth outcomes. Trace elements in umbilical cord serum and colostrum of the studied population were relatively high compared with other populations. The geometric means (GM) of estimated daily intake (EDI, mgday(-1)) of the trace elements were in the safe ranges for infant Dietary Reference Intakes (DRIs) recommended by the United States Food and Drug Administration (FDA). When using total dietary intake (TDI, mgkg(-1)bwday(-1)), zinc (Zn) (0.880mgkg(-1)bwday(-1)) and selenium (Se) (6.39×10(-3)mgkg(-1)bwday(-1)) were above the Reference Doses (RfD), set by the United States Environmental Protection Agency (EPA). Multivariable linear regression analyses showed that Se was negatively correlated with birth outcomes. Our findings suggested that overloading of trace elements due to environmental contamination may contribute to negative birth outcomes. Copyright © 2016 Elsevier B.V. All rights reserved.

Introduction: Against a paucity of evidence, a model describing elements of health governance best suited to achieving integrated care internationally was developed. The aim of this study was to explore how health meso-level organisations used, or planned to use, the governance elements. Methods: A case study design was used to offer two contrasting contexts of health governance. Semi-structured interviews were conducted with participants who held senior governance roles. Data were thematically analysed to identify if the elements of health governance were being used, or intended to be in the future. Results: While all participants agreed that the ten elements were essential to developing future integrated care, most were not used. Three major themes were identified: (1) organisational versus system focus, (2) leadership and culture, and, (3) community (dis)engagement. Discussion: Several barriers and enablers to the use of the elements were identified and would require addressing in order to make evidence-based changes. Conclusion: Despite a clear international policy direction in support of integrated care this study identified a number of significant barriers to its implementation. The study reconfirmed that a focus on all ten elements of health governance is essential to achieve integrated care. PMID:29588645

Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health.

Herndon, J Marvin

2015-08-11

The widespread, intentional and increasingly frequent chemical emplacement in the troposphere has gone unidentified and unremarked in the scientific literature for years. The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health. Two methods are employed: (1) Comparison of 8 elements analyzed in rainwater, leached from aerosolized particulates, with corresponding elements leached into water from coal fly ash in published laboratory experiments, and (2) Comparison of 14 elements analyzed in dust collected outdoors on a high-efficiency particulate air (HEPA) filter with corresponding elements analyzed in un-leached coal fly ash material. The results show: (1) the assemblage of elements in rainwater and in the corresponding experimental leachate are essentially identical. At a 99% confidence interval, they have identical means (T-test) and identical variances (F-test); and (2) the assemblage of elements in the HEPA dust and in the corresponding average un-leached coal fly ash are likewise essentially identical. The consequences on public health are profound, including exposure to a variety of toxic heavy metals, radioactive elements, and neurologically-implicated chemically mobile aluminum released by body moisture in situ after inhalation or through transdermal induction.

Deficiencies of micronutrients, including essential trace elements, affect up to 3 billion people worldwide. The dietary availability of trace elements is determined largely by their soil concentrations. Until now, the mechanisms governing soil concentrations have been evaluated in small-scale studies, which identify soil physicochemical properties as governing variables. However, global concentrations of trace elements and the factors controlling their distributions are virtually unknown. We used 33,241 soil data points to model recent (1980–1999) global distributions of Selenium (Se), an essential trace element that is required for humans. Worldwide, up to one in seven people have been estimated to have low dietary Se intake. Contrary to small-scale studies, soil Se concentrations were dominated by climate–soil interactions. Using moderate climate-change scenarios for 2080–2099, we predicted that changes in climate and soil organic carbon content will lead to overall decreased soil Se concentrations, particularly in agricultural areas; these decreases could increase the prevalence of Se deficiency. The importance of climate–soil interactions to Se distributions suggests that other trace elements with similar retention mechanisms will be similarly affected by climate change. PMID:28223487

Summary Bromine is ubiquitously present in animals as ionic bromide (Br−) yet has no known essential function. Herein, we demonstrate that Br− is a required cofactor for peroxidasin-catalyzed formation of sulfilimine crosslinks, a post-translational modification essential for tissue development and architecture found within the collagen IV scaffold of basement membranes (BMs). Bromide, converted to hypobromous acid, forms a bromosulfonium-ion intermediate that energetically selects for sulfilimine formation. Dietary Br-deficiency is lethal in Drosophila while Br-replenishment restores viability, demonstrating its physiologic requirement. Importantly, Br-deficient flies phenocopy the developmental and BM defects observed in peroxidasin mutants and indicate a functional connection between Br−, collagen IV, and peroxidasin. We establish that Br− is required for sulfilimine formation within collagen IV, an event critical for BM assembly and tissue development. Thus, bromine is an essential trace element for all animals and its deficiency may be relevant to BM alterations observed in nutritional and smoking related disease. PMID:24906154

Educational psychology indicates that learning processes can be mapped on three dimensions: cognitive (what to learn), affective or motivational (why learn), and metacognitive regulation (how to learn). In a truly student-centered medical curriculum, all three dimensions should guide curriculum developers in constructing learning environments. The authors explored whether student motivation has guided medical education curriculum developments. The authors reviewed the literature on motivation theory related to education and on medical education curriculum development to identify major developments. Using the Learning-Oriented Teaching model as a framework, they evaluated the extent to which motivation theory has guided medical education curriculum developers. Major developments in the field of motivation theory indicate that motivation drives learning and influences students' academic performance, that gender differences exist in motivational mechanisms, and that the focus has shifted from quantity of motivation to quality of motivation and its determinants, and how they stimulate academic motivation. Major developments in medical curricula include the introduction of standardized and regulated medical education as well as problem-based, learner-centered, integrated teaching, outcome-based, and community-based approaches. These curricular changes have been based more on improving students' cognitive processing of content or metacognitive regulation than on stimulating motivation. Motivational processes may be a substantially undervalued factor in curriculum development. Building curricula to specifically stimulate motivation in students may powerfully influence the outcomes of curricula. The elements essential for stimulating intrinsic motivation in students, including autonomy support, adequate feedback, and emotional support, appear lacking as a primary aim in many curricular plans.

Since the introduction of mobile phones, technology has been increasingly used to enable diabetes self-management education and support. This timely systematic review summarizes how currently available technology impacts outcomes for people living with diabetes. A systematic review of high quality review articles and meta analyses focused on utilizing technology in diabetes self-management education and support services was conducted. Articles were included if published between January 2013 and January 2017. Twenty-five studies were included for analysis. The majority evaluated the use of mobile phones and secure messaging. Most studies described healthy eating, being active and metabolic monitoring as the predominant self-care behaviors evaluated. Eighteen of 25 reviews reported significant reduction in A1c as an outcome measure. Four key elements emerged as essential for improved A1c: (1) communication, (2) patient-generated health data, (3) education, and (4) feedback. Technology-enabled diabetes self-management solutions significantly improve A1c. The most effective interventions incorporated all the components of a technology-enabled self-management feedback loop that connected people with diabetes and their health care team using 2-way communication, analyzed patient-generated health data, tailored education, and individualized feedback. The evidence from this systematic review indicates that organizations, policy makers and payers should consider integrating these solutions in the design of diabetes self-management education and support services for population health and value-based care models. With the widespread adoption of mobile phones, digital health solutions that incorporate evidence-based, behaviorally designed interventions can improve the reach and access to diabetes self-management education and ongoing support.

The mental training (Galloway, 2011) is one of the measures of the psychological preparation in sport. Especially such as the judo discipline requires the mental training, due to the fact that the judo is a combat sport, the direct, physical confrontation of two opponents. Hence the mental preparation should be an essential element of preparing for the sports fight. In the article are described the basics of the AR systems and presents selected elements of the AR systems: sight glasses Vuzix glasses, Kinect sensor and an interactive floor Multitap. Next, there are proposed the scenarios for using the AR in the mental training which are based on using both Vuzix glasses type head as well as the interactive floor Multitap. All options, except for the last, are provided for using the Kinect sensor. In addition, these variants differ as to the primary user of the system. It can be an competitor, his coach the competitor and the coach at the same time. In the end of the article are presented methods of exploring, both, the effectiveness and usefulness, and/or the User Experience of the proposed prototypes. There are presented three educational training simulator prototype models in sport (judo) describing their functionality based on the theory of sports training (the cyclical nature of sports training) and the theory of subtle interactions, enabling an explanation of the effects of sports training using the augmented reality technology.

Thermodynamic Considerations of Contamination by Alloying Elements of Remelted End-of-Life Nickel- and Cobalt-Based Superalloys

Cobalt and nickel are high-value commodity metals and are mostly used in the form of highly alloyed materials. The alloying elements used may cause contamination problems during recycling. To ensure maximum resource efficiency, an understanding of the removability of these alloying elements and the controllability of some of the primary alloying elements is essential with respect to the recycling of end-of-life (EoL) nickel- and cobalt-based superalloys by remelting. In this study, the distribution behaviors of approximately 30 elements that are usually present in EoL nickel- and cobalt-based superalloys in the solvent metal (nickel, cobalt, or nickel-cobalt alloy), oxide slag, and gas phases during the remelting were quantitatively evaluated using a thermodynamic approach. The results showed that most of the alloying elements can be removed either in the slag phase or into the gas phase. However, the removal of copper, tin, arsenic, and antimony by remelting is difficult, and they remain as tramp elements during the recycling. On the other hand, the distribution tendencies of iron, molybdenum, and tungsten can be controlled by changing the remelting conditions. To increase the resource efficiency of recycling, preventing contamination by the tramp elements and identifying the alloying compositions of EoL superalloys are significantly essential, which will require the development of efficient prior alloy-sorting systems and advanced separation technologies.

A general algorithm using finite element method for aerodynamic configurations at low speeds

NASA Technical Reports Server (NTRS)

Balasubramanian, R.

1975-01-01

A finite element algorithm for numerical simulation of two-dimensional, incompressible, viscous flows was developed. The Navier-Stokes equations are suitably modelled to facilitate direct solution for the essential flow parameters. A leap-frog time differencing and Galerkin minimization of these model equations yields the finite element algorithm. The finite elements are triangular with bicubic shape functions approximating the solution space. The finite element matrices are unsymmetrically banded to facilitate savings in storage. An unsymmetric L-U decomposition is performed on the finite element matrices to obtain the solution for the boundary value problem.

The maternal transfer of trace elements is a process by which offspring may accumulate trace elements from their maternal parent. Although maternal transfer has been assessed in many vertebrates, there is little understanding of this process in invertebrate species. This study investigated the maternal transfer of 13 trace elements (Ag, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) in Atlantic horseshoe crab (Limulus polyphemus) eggs and compared concentrations to those in adult leg and gill tissue. For the majority of individuals, all trace elements were transferred, with the exception of Cr, from the female to the eggs. The greatest concentrations on average transferred to egg tissue were Zn (140 µg/g), Cu (47.8 µg/g), and Fe (38.6 µg/g) for essential elements and As (10.9 µg/g) and Ag (1.23 µg/g) for nonessential elements. For elements that were maternally transferred, correlation analyses were run to assess if the concentration in the eggs were similar to that of adult tissue that is completely internalized (leg) or a boundary to the external environment (gill). Positive correlations between egg and leg tissue were found for As, Hg, Se, Mn, Pb, and Ni. Mercury, Mn, Ni, and Se were the only elements correlated between egg and gill tissue. Although, many trace elements were in low concentration in the eggs, we speculate that the higher transfer of essential elements is related to their potential benefit during early development versus nonessential trace elements, which are known to be toxic. We conclude that maternal transfer as a source of trace elements to horseshoe crabs should not be overlooked and warrants further investigation.

Essential nutrients are critical for physiological processes of organisms. In fish, they are obtained primarily from the diet, and their transfer and accumulation are known to be impacted by environmental variables such as water temperature, pH and salinity, as well as by diet composition and matrices. Yet, prey items consumed by fish may also contain toxic compounds such as marine toxins associated with harmful algae. These biotoxins have the potential to affect essential trace element assimilation in fish through chemical interactions such as the formation of trace element-toxin complexes or by affecting general fish physiology as in the modification of ion-specific transport pathways. We assessed the influence of dietary exposure to brevetoxins (PbTxs), ichthyotoxic neurotoxins produced by the dinoflagellate Karenia brevis, on trophic transfer of two essential trace elements, Mn and Zn, in a fish model. Using ecologically relevant concentrations of PbTxs and trace elements in controlled laboratory conditions, juvenile turbots Scophthalmus maximus were given food containing PbTxs before or at the same time as a feeding with radiotracers of the chosen essential elements ( 54 Mn and 65 Zn). Treatments included simultaneous exposure (PbTxs +  54 Mn +  65 Zn) in a single-feeding, 3-week daily pre-exposure to dietary PbTx followed by a single feeding with 54 Mn and 65 Zn, and a control ( 54 Mn and 65 Zn only). After a 21-day depuration period, turbot tissue brevetoxin levels were quantified and assimilation efficiencies of 54 Mn and 65 Zn were assessed. PbTxs were found in turbot tissues in each exposure treatment, demonstrating dietary trophic transfer of these toxins; yet, no differences in assimilation efficiencies of Mn or Zn were found between treatments or the control (p > 0.05). These results indicate that, in our experimental conditions, PbTx exposure does not significantly affect the trophic transfer of Mn and Zn in fish. Copyright © 2018 Elsevier B.V.

Exposure to essential and non-essential elements may be elevated for green sea turtles (Chelonia mydas) that forage close to shore. Biomonitoring of trace elements in turtle blood can identify temporal trends over repeated sampling events, but any interpretation of potential health risks due to an elevated exposure first requires a comparison against a baseline. This study aims to use clinical reference interval (RI) methods to produce exposure baseline limits for essential and non-essential elements (Na, Mg, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Sb, Ba, and Pb) using blood from healthy subadult turtles foraging in a remote and offshore part of the Great Barrier Reef. Subsequent blood biomonitoring of three additional coastal populations, which forage in areas dominated by agricultural, urban and military activities, showed clear habitat-specific differences in blood metal profiles relative to the those observed in the offshore population. Coastal turtles were most often found to have elevated concentrations of Co, Mo, Mn, Mg, Na, As, Sb, and Pb relative to the corresponding RIs. In particular, blood from turtles from the agricultural site had Co concentrations ranging from 160 to 840 μg/L (4-25 times above RI), which are within the order expected to elicit acute effects in many vertebrates. Additional clinical blood biochemistry and haematology results indicate signs of a systemic disease and the prevalence of an active inflammatory response in a high proportion (44%) of turtles from the agricultural site. Elevated Co, Sb, and Mn in the blood of these turtles significantly correlated with elevated markers of acute inflammation (total white cell counts) and liver dysfunction (alkaline phosphatase and total bilirubin). The results of this study support the notion that elevated trace element exposures may be adversely affecting the health of nearshore green sea turtles. Copyright © 2016 Elsevier Ltd.

Social support helps prevent burnout and promotes its positive opposite, work engagement. With higher work engagement performance increases. The context-specific aspects of social support for medical educators, in their educator role, are unknown. To help facilitate social support our study describes the essential elements of social support and their meaning for medical educators. We held interviews with medical educators purposefully sampled for diverse backgrounds and working circumstances and who spent a considerable amount of time on education. Both clinicians and basic scientists participated. The Pictor technique guided the interviews. Participants were invited to talk about the breadth of social support and elaborate on meaningful experiences. Template analysis was used for a descriptive phenomenological approach. Thirteen medical educators were interviewed. We identified four themes: (i) sources of support and their intent (e.g. a superior with the intent to stimulate personal growth); (ii) the materialisation of support (e.g. sought or offered); (iii) its manifestation (e.g. the act of providing protected time); and (iv) the overarching effect of social support, both in terms of practical effects and the meaning of support. We identified three sorts of meanings of social support for educators. Receiving support could lead to (i) feeling reassured and confident; (ii) feeling encouraged and determined and (iii) a sense of relatedness and acknowledgement of the educator role. Support for education comes from a wide range of sources because it is both sought and offered beyond the boundaries of the educational role. The resulting differences in support provided necessitate that educational leaders and policymakers consider the sources available to each educator, connecting educators where necessary. When facilitating or designing social support it is important that the need to feel reassured, encouraged or related is met. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Sardinian (Italy) island population has a uniquely high incidence of amyotrophic lateral sclerosis (ALS). Essential trace element levels in blood, hair, and urine of ALS Sardinian patients were investigated in search of valid biomarkers to recognize and predict ALS. Six elements (Ca, Cu, Fe, Mg, Se, and Zn) were measured in 34 patients compared to 30 age- and sex-matched healthy controls by a validated method. Levels of Ca and Cu in blood and of Se and Zn in hair were significantly higher in ALS than in controls, while urinary excretion of Mg and Se was significantly decreased. The selected cut-off concentrations for these biomarkers may distinguish patients with or without ALS with sufficient sensitivity and specificity. Many positive (as Se-Cu and Se-Zn) and negative associations (as Ca-Mg and Ca-Zn) between elements suggested that multiple metals involved in multiple mechanisms have a role in the ALS degeneration.

Outpatient specialty consultations rely on the timeliness and completeness of referral information to facilitate a valuable patient-specialist interaction. This project aimed to increase essential diagnostic information availability at the initial consultation for patients referred for common endocrine conditions frequently lacking such data-diabetes mellitus, thyroid nodule, thyrotoxicosis, and hypercalcemia. At an endocrinology clinic at an academic medical center in rural New England, providers see several thousand new patients annually, the majority of whom are referred by providers external to the clinic's healthcare system. Through consensus, endocrinology clinic providers agreed on the two or three data elements essential for a meaningful initial consultation for each. A quality improvement team employed a planned series of interventions based on previously published methods and an innovative approach: dissemination of a referral guideline, an assessment of referral adequacy in the endocrinology clinic workflow, coupled with focused requests for missing items, and a pre-visit lab appointment. Between April 2015 and March 2016, 762 referrals were reviewed. At baseline for the four conditions, referrals contained all essential elements only 27.5% (22 of 80) of the time. Over a 7-month period, the team implemented the interventions, with subsequent referrals containing all essential elements increasing to 75.5% (P<.0001), largely attributable to the pre-visit lab appointment. Incoming referrals that lack essential information are a significant problem in specialty care and may adversely affect patient experience, provider satisfaction, and clinic efficiency. Improvement may require innovative approaches, such as the potentially transferable and generalizable ones employed here.

Identification of an activator protein required for the induction of fruA, a gene essential for fruiting body development in Myxococcus xanthus

Myxococcus xanthus exhibits social behavior and multicellular development. FruA is an essential transcription factor for fruiting body development in M. xanthus. In the present study, the upstream promoter region was found to be necessary for the induction of fruA expression during development. A cis-acting element required for the induction was identified and was located between nucleotides –154 and –107 with respect to the transcription initiation site. In addition, it was found that two binding sites exist within this element of the fruA promoter. By using DNA affinity column chromatography containing the cis-acting element, a fruA promoter-binding protein was purified. The purified protein was shown by N-terminal sequence analysis to be identical to MrpC, a protein identified previously by transposon insertion mutagenesis as an essential locus for fruiting body development [Sun, H. & Shi, W. (2001) J. Bacteriol. 183, 4786–4795]. Furthermore, fruA mRNA was not detectable in the mrpC::km strain, demonstrating that MrpC is essential for fruA expression. Moreover, mutational analysis of the binding sites for MrpC in the fruA promoter indicates that binding of MrpC activates transcription of fruA in vivo. This report provides evidence for a direct molecular interaction involved in temporally regulated gene expression in M. xanthus. PMID:12851461

Coal fly ash (CFA) is a problematic solid waste all over the world. One distinct beneficial reuse of CFA is its utilization in land application as a soil amendment. A pot experiment was carried out to assess the feasibility of using CFA to improve plant growth and increase the supply of plant-essential elements and selenium (Se) of a loessial soil for agricultural purpose. Plants of alfalfa (Medicago sativa) were grown in a loessial soil amended with different rates (5%, 10%, 20% and 40%) of CFA for two years and subjected to four successive cuttings. Dry mass of shoots and roots, concentrations of plant-essential elements and Se in plants were measured. Shoot dry mass and root dry mass were always significantly increased by 5%, 10% and 20% CFA treatments, and by 40% CFA treatment in all harvests except the first one. The CFA had a higher supply of exchangeable phosphorus (P), magnesium (Mg), copper (Cu), zinc (Zn), molybdenum (Mo), and Se than the loessial soil. Shoot P, calcium (Ca), Mg, Mo, boron (B), and Se concentrations were generally markedly increased, but shoot potassium (K), Cu, and Zn concentrations were generally reduced. The CFA can be a promising source of some essential elements and Se for plants grown in the loessial soil, and an application rate of not higher than 5% should be safe for agricultural purpose without causing plant toxicity symptoms in the studied loessial soil and similar soils. Field trials will be carried out to confirm the results of the pot experiment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cytosolic distributions of nonessential metals Cd and Tl and seven essential elements among compounds of different molecular masses were studied in the liver of brown trout (Salmo trutta) from the karstic Krka River in Croatia. Analyses were done by size exclusion high performance liquid chromatography and high resolution inductively coupled plasma mass spectrometry. Common feature of Cd and Tl, as highly toxic elements, was their distribution within only two narrow peaks. The increase of cytosolic Cd concentrations was reflected in marked increase of Cd elution within low molecular mass peak (maximum at ∼15 kDa), presumably containing metallothioneins (MTs), which indicated successful Cd detoxification in brown trout liver under studied exposure conditions. Contrary, the increase of cytosolic Tl concentrations was reflected in marked increase of Tl elution within high molecular mass peak (maximum at 140 kDa), which probably indicated incomplete Tl detoxification. Common feature of the majority of studied essential elements was their distribution within more peaks, often broad and not well resolved, which is consistent with their numerous physiological functions. Among observed associations of essential metals/nonmetal to proteins, the following could be singled out: Cu and Zn association to MTs, Fe association to storage protein ferritin, and Se association to compounds of very low molecular masses (<5 kDa). The obtained results present the first step towards identification of metal-binding compounds in hepatic cytosol of brown trout, and thus a significant contribution to better understanding of metal fate in the liver of that important bioindicator species.

Perception of hospital learning environment: a survey of Hong Kong nursing students.

PubMed

Chan, Dominic S K; Ip, Wan Y

2007-10-01

The last two decades have seen widespread changes to nurse education but the clinical field remains an essential and invaluable resource in preparing students for the reality of their professional role, supporting the integration of theory and practice, and linking the 'knowing what' to do with the 'knowing how' to deliver care. The clinical learning environment represents a vital element of nurse education that needs to be measurable and warrants further investigation. This survey study examined Hong Kong nursing students' perception of the social climate of the clinical learning environment. Participants were invited to complete the two versions, the Actual and Preferred Forms, of the Clinical Learning Environment Inventory following the completion of their clinical field placement. Two hundred eighty one Actual Forms and 243 Preferred Forms returned. SPPS version 11 was employed to analyse data with descriptive and inferential statistics. It was found that there were significant differences between students' perceptions of the actual clinical learning environment and the ideal clinical learning environment they desired. The study highlights the need for a supportive clinical learning environment which is of paramount importance for students in clinical practice.

Online course design for teaching critical thinking.

Schaber, Patricia; Shanedling, Janet

2012-01-01

Teaching critical thinking (CT) skills, a goal in higher education, is seldom considered in the primary design of either classroom or online courses, and is even less frequently measured in student learning. In health professional education, CT along with clinical reasoning skills is essential for the development of clinical practitioners. This study, measuring CT skill development in an online theory course, supports using a cyclical course design to build higher level processes in student thinking. Eighty-six Masters of Occupational Therapy students in four sections of an occupation-based theory course were evaluated on elements in the Paul and Elder CT Model throughout the course and surveyed for their perceptions in their ability to think critically at course completion. Results of this study demonstrated that the online theory course design contributed to improving critical thinking skills and student's perceived CT skill development as applicable to their future professional practice. In a focus group, eight students identified four effective course design features that contributed to their CT skill development: highly structured learning, timely feedback from instructor, repetition of assignments, and active engagement with the material.

Pre-registration student nurses perception of the hospital-learning environment during clinical placements.

Midgley, Kirsten

2006-05-01

If we subscribe to the notion that nursing is an action profession, that nurses learn by doing [Neary, M., 2000. Responsive assessment: assessing student nurses' clinical competence. Nurse Education Today 21, 3-17], then the mastery of fundamental clinical skills must be a key component of courses leading to registration. The last two decades have seen widespread changes to nurse education but the clinical field remains an invaluable resource in preparing students for the reality of their professional role supporting the integration of theory and practice and linking the 'knowing what' with the 'knowing how'. The clinical-learning environment represents an essential element of nurse education that needs to be measurable and warrants further investigation. This exploratory cohort study (n = 67) examined pre-registration student nurses' perception of the hospital-learning environment during clinical placements together with the key characteristics of the students' preferred learning environment utilising an established tool, the clinical-learning environment inventory (CLEI) tool [Chan, D., 2001a. Development of an innovative tool to assess hospital-learning environments. Nurse Education Today 21, 624-631; Chan, D., 2001b. Combining qualitative and quantitative methods in assessing hospital-learning environments. International Journal of Nursing Studies 3, 447-459]. The results demonstrated that in comparison with the actual hospital environment, students would prefer an environment with higher levels of individualisation, innovation in teaching and learning strategies, student involvement, personalisation and task orientation.

this article constitutes a report on the comprehensive Nituuchischaayihtitaau Aschii multi-community environment-and-health study conducted among the Cree peoples (Eeyouch) of northern Quebec, Canada. to interpret observed concentrations of a suite of chemical elements in a multi-media biological monitoring study in terms of sources and predictors. the concentrations of 5 essential and 6 toxic chemical elements were measured in whole blood, and/or in urine or hair by ICP-MS. Concentrations of essential elements are compared to those considered normal (i.e., required for good health) and, when toxic, deemed acceptable at specified concentrations in public health guidelines. Their dependence on age, sex, the specific community lived-in and diet were explored employing multivariate analysis of variance (MANOVA) involving new variables generated by principle component analysis (PCA) and correspondence analysis (CA). the 5 most prominent PCA axes explained 67.7% of the variation, compared to 93.0% by 6 main CA factors. Concentrations of the essential elements in whole blood (WB) and iodine(i) and arsenic (As) in urine were comparable to those reported in the recent Canadian Health Measures survey and are assigned to dietary sources. By contrast, WB cadmium (Cd) was elevated even when smoking was considered. Mercury (Hg) concentrations in WB and hair were also higher in adults, although comparable to those observed for other indigenous populations living at northern latitudes. Fish consumption was identified as the prominent source. Of the 5 coastal communities, all but one had lower Hg exposures than the four inland communities, presumably reflecting the type of fish consumed. Use of firearms and smoking were correlated with WB-lead (Pb). The concentrations of both Hg and Pb increased with age and were higher in men, while WB-Cd and smoking prevalence were higher in women when considering all communities. Hg and Pb were low in children and women of reproductive age, with few exceedances of health guidelines. Although individuals with T2D had somewhat lower WB-Cd, there is some indication that Cd may potentiate renal dysfunction in this subgroup. Plots of selected CA axes grouped those elements expected to be in a normal diet and distinguished them from those with well-known unique sources (especially Hg and As in hair; and Hg, Pb and Cd in WB). the use of multiple biological media in conjunction with the complementary PCA and CA approaches for constructing composite variables allowed a more detailed understanding of both the sources of the essential and toxic elements in body fluids and the dependencies of their observed concentrations on age, sex, community and diet.

As the number of prison inmates facing end-stage chronic illness grows, more prisons across the U.S. must address the need for end-of-life care. Many will likely need to develop a plan with potentially limited resources and external support. This case study presents one long-running model of care, the Louisiana State Penitentiary Prison Hospice Program. Based on field observations and in-depth interviews with hospice staff, inmate volunteers and corrections officers, we identify five essential elements that have contributed to the long-term operation of this program: patient-centered care, an inmate volunteer model, safety and security, shared values, and teamwork. We describe key characteristics of each of these elements, discuss how they align with earlier recommendations and research, and show how their integration supports a sustained model of prison end-of-life care.

Chemical classification and labelling systems may be roughly similar from one country to another but there are significant differences too. In order to harmonize various chemical classification systems and ultimately provide consistent chemical hazard communication tools worldwide, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was endorsed by the United Nations Economic and Social Council (ECOSOC). Several countries, including Japan, Taiwan, Korea and Malaysia, are now in the process of implementing GHS. It is essential to ascertain the comprehensibility of chemical hazard communication tools that are described in the GHS documents, namely the chemical labels and Safety Data Sheets (SDS). Comprehensibility Testing (CT) was carried out with a mixed group of industrial workers in Malaysia (n=150) and factors that influence the comprehensibility were analysed using one-way ANOVA. The ability of the respondents to retrieve information from the SDS was also tested in this study. The findings show that almost all the GHS pictograms meet the ISO comprehension criteria and it is concluded that the underlying core elements that enhance comprehension of GHS pictograms and which are also essential in developing competent persons in the use of SDS are training and education.

Pulmonary tuberculosis (PTB) is a serious public threat throughout the world. PTB and smoking have a strong correlation. Malnutrition, poverty, addiction, overcrowding, illiteracy, unemployment, and poor hygienic conditions are the collective aspects for the disease progress. Pakistan is the fifth among 22 high tuberculosis (TB) burden countries and the fourth regarding multidrug-resistant tuberculosis (MDR-TB). The aim of study was to determine the concentration of essential and toxic elements from blood samples of smoker and nonsmoker PTB patients by inductively coupled plasma mass spectrometry (ICP-MS) followed by microwave acid digestion and compared with control subjects (n = 30). Eighty PTB patients were selected from different hospitals with age ranging 20-70 years. It was interpreted that the mean age among males and females was found to be 35.6 ± 1.4 and 33.5 ± 1.2, respectively, and the male patients were highly affected in contrast to females. Essential elements such as Mn, Fe, Zn, and Se were statistically found to be lower while Ca, Co, and Cu were found to be higher compared to the control group (p = 0.00). However, toxic elements like Al, Cr, Ni, As, Cd, and Pb were statistically elevated in smokers than nonsmokers. Further research is needed to understand the degree of the impact of essential trace elements on treatment outcome (follow-up) followed by balanced healthy nutritional supplementation along with medical therapy, consequently improving the pulmonary tuberculosis outcome and survival as well.

2016-01-01

Objective We assess how countries in regions of the world where maternal mortality is highest - South Asia and Sub-Saharan Africa - are performing with regards to providing women with vital elements of the continuum of care. Methods Using recent Demographic and Health Survey data from nine countries including 18,036 women, descriptive and multilevel regression analyses were conducted on four key elements of the continuum of care - at least one antenatal care visit, four or more antenatal care visits, delivery with a skilled birth attendant and postnatal checks for the mother within the first 24 hours since birth. Family planning counseling within a year of birth was also included in the descriptive analyses. Results Results indicated that a major drop-out (more than 50%) occurs early on in the continuum of care between the first antenatal care visit and four or more antenatal care visits. Few women (less than 5%) who do not receive any antenatal care go on to have a skilled delivery or receive postnatal care. Women who receive some or all the elements of the continuum of care have greater autonomy and are richer and more educated than women who receive none of the elements. Conclusion Understanding where drop-out occurs and who drops out can enable countries to better target interventions. Four or more ANC visits plays a pivotal role within the continuum of care and warrants more programmatic attention. Strategies to ensure that vital services are available to all women are essential in efforts to improve maternal health. PMID:26511130

For the safe use of lasers in educational institutions: elementary through university

NASA Astrophysics Data System (ADS)

Seeber, Fredrick P.

1995-10-01

The use of lasers by the academic community continues to dramatically escalate. Academia is inundated with a profusion of lasers, each with a diverse function. Traditional departments such as biology, chemistry, and physics have introduced the use of lasers as an essential element of tutelage. Even the more distinctive departments such as Cancer Research, Civil Engineering, Earth and Planetary Science, Plasma Fusion, Spectroscopy, and so forth, have incorporated the laser in the composition of their educational mechanism. The literature indicates most ocular accidents happen during alignment procedures, which is an everyday activity for educational laboratories. Also, the improper use of laser safety eye wear is a major area of concern for laser safety in education institutions. More Class II, III, and IV lasers are used in universities, colleges, laser electro-optic technical colleges and high schools than probably any other area: for teaching, research, laboratory experiments, and demonstrations. Relatively large numbers of students work in laboratory groups in confined area, with various lasers of different wavelengths in the same laboratory. Open cavity and beam paths of Class IV lasers are common in these environments. Most educational institutions do not have laser safety officers or standard operation procedures. This paper will discuss the development of a new laser safety standard by an ANSI ad-hoc committee and by the executive committee of the ANSI Z-136 intended to provide adequate, reasonable, and practical guidance for educators, students, and spectators found in classrooms, lecture halls, and laboratories associated with universities, colleges, high, and elementary schools.

Science as a general education: Conceptual science should constitute the compulsory core of multi-disciplinary undergraduate degrees.

PubMed

Charlton, Bruce G

2006-01-01

It is plausible to assume that in the future science will form the compulsory core element both of school curricula and multi-disciplinary undergraduate degrees. But for this to happen entails a shift in the emphasis and methods of science teaching, away from the traditional concern with educating specialists and professionals. Traditional science teaching was essentially vocational, designed to provide precise and comprehensive scientific knowledge for practical application. By contrast, future science teaching will be a general education, hence primarily conceptual. Its aim should be to provide an education in flexible rationality. Vocational science teaching was focused on a single-discipline undergraduate degree, but a general education in abstract systematic thinking is best inculcated by studying several scientific disciplines. In this sense, 'science' is understood as mathematics and the natural sciences, but also the abstract and systematic aspects of disciplines such as economics, linguistics, music theory, history, sociology, political science and management science. Such a wide variety of science options in a multi-disciplinary degree will increase the possibility of student motivation and aptitude. Specialist vocational science education will progressively be shifted to post-graduate level, in Masters and Doctoral programs. A multi-disciplinary and conceptually-based science core curriculum should provide an appropriate preparation for dealing with the demands of modern societies; their complex and rapidly changing social systems; and the need for individual social and professional mobility. Training in rational conceptual thinking also has potential benefits to human health and happiness, since it allows people to over-ride inappropriate instincts, integrate conflicting desires and pursue long-term goals.

Environmental matrices including soils, sediments, and living organisms are reservoirs of several essential as well as non-essential elements. Accurate qualitative and quantitative information on the distribution and interaction of biologically significant elements is vital to understand the role of these elements in environmental and biological samples. Synchrotron micro-X-ray fluorescence (μ-SXRF) allows in situ mapping of biologically important elements at nanometer to sub-micrometer scale with high sensitivity, negligible sample damage and enable tuning of the incident energy as desired. Beamlines in the synchrotron facilities are rapidly increasing their analytical versatility in terms of focusing optics, detector technologies, incident energy, and sample environment. Although extremely competitive, it is now feasible to find stations offering complimentary techniques like micro-X-ray diffraction (μ-XRD) and micro-X-ray absorption spectroscopy (μ-XAS) that will allow a more complete characterization of complex matrices. This review includes the most recent literature on the emerging applications and challenges of μ-SXRF in studying the distribution of biologically important elements and manufactured nanoparticles in soils, sediments, plants, and microbes. The advantages of using μ-SXRF and complimentary techniques in contrast to conventional techniques used for the respective studies are discussed. Copyright © 2012 Elsevier B.V. All rights reserved.

Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health

PubMed Central

Herndon, J. Marvin

2015-01-01

The widespread, intentional and increasingly frequent chemical emplacement in the troposphere has gone unidentified and unremarked in the scientific literature for years. The author presents evidence that toxic coal combustion fly ash is the most likely aerosolized particulate sprayed by tanker-jets for geoengineering, weather-modification and climate-modification purposes and describes some of the multifold consequences on public health. Two methods are employed: (1) Comparison of 8 elements analyzed in rainwater, leached from aerosolized particulates, with corresponding elements leached into water from coal fly ash in published laboratory experiments, and (2) Comparison of 14 elements analyzed in dust collected outdoors on a high-efficiency particulate air (HEPA) filter with corresponding elements analyzed in un-leached coal fly ash material. The results show: (1) the assemblage of elements in rainwater and in the corresponding experimental leachate are essentially identical. At a 99% confidence interval, they have identical means (T-test) and identical variances (F-test); and (2) the assemblage of elements in the HEPA dust and in the corresponding average un-leached coal fly ash are likewise essentially identical. The consequences on public health are profound, including exposure to a variety of toxic heavy metals, radioactive elements, and neurologically-implicated chemically mobile aluminum released by body moisture in situ after inhalation or through transdermal induction.

Matrix elements and duality for type 2 unitary representations of the Lie superalgebra gl(m|n)

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

Werry, Jason L.; Gould, Mark D.; Isaac, Phillip S.

The characteristic identity formalism discussed in our recent articles is further utilized to derive matrix elements of type 2 unitary irreducible gl(m|n) modules. In particular, we give matrix element formulae for all gl(m|n) generators, including the non-elementary generators, together with their phases on finite dimensional type 2 unitary irreducible representations which include the contravariant tensor representations and an additional class of essentially typical representations. Remarkably, we find that the type 2 unitary matrix element equations coincide with the type 1 unitary matrix element equations for non-vanishing matrix elements up to a phase.

A hydrogen sensor element comprises an essentially inert, electrically-insulating substrate having a thin-film metallization deposited thereon which forms at least two resistors on the substrate. The metallization comprises a layer of Pd or a Pd alloy for sensing hydrogen and an underlying intermediate metal layer for providing enhanced adhesion of the metallization to the substrate. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors, and at least one of the resistors is left uncovered. The difference in electrical resistances of the covered resistor and the uncovered resistor is related to hydrogen concentration in a gas to which the sensor element is exposed.

Medicinal herbs are used for the treatment of different ailments since antiquity. Different parts of Anethum sowa L. is used in folk medicine as a carminative for the treatment of flatulence, colic and hiccups of infants and children, antioxidant, antimicrobial and antispasmodic agent. The aim of our present study is to evaluate the chemical composition of the essential oil, proximate and elemental composition, amino acid, fatty acid profile and thermal behaviour of its root part as well as different pharmacological activities like antioxidant, antimicrobial and cytotoxicity of the root essential oil. The air-dried roots of Anethum sowa L. were subjected to hydro-distillation to yield the essential oil. The antioxidant activity of the essential oil was studied by DPPH radical scavenging activity. The antimicrobial activity was tested against four Gram-positive, six Gram-negative bacteria and four fungi species. The minimum inhibitory concentration (MIC) and Minimum bacterial concentration (MBC) for each examined microorganism were determined using the micro-dilution method. The LC 50 value of the oil was also evaluated by brine shrimp lethality assay. The subsequent proximate analysis was also done by AOAC methods. The elemental analysis of the root powder was analysed by ICP-MS, AAS and FP system. The fatty acid was extracted by hot and cold extraction method and the analyses were carried out by GC. The amino acid profile was done by the amino acid analyzer. The DTA, DTG and TG of the root powder were taken by the thermogravimetric analyzer. A total of 24 constituents was identified and quantified in the essential oil and its water extract portion by GC and GC-MS. Apiol (81.99 and 74.779%) was found the highest phenylpropanoid constituent followed by m-diaminobenzene (10.446 and 8.778%) in the essential oil and aqueous extract portion. On the other hand, β-butyrolactone (5.13%) and isobutyl acetone (3.73%) were found in the major constituents in the water extract part. The IC 50 value of the essential oil was found to be 3.07 mg/mL by DPPH radical assay methods. The LC 50 value of the brine shrimp cytotoxicity assay of the essential oil was observed at 0.81 μg/mL. The essential oil showed better activity on Gram-negative bacteria than Gram-positive bacteria and fungi. The proximate composition showed that root contained 5.29% ash, 2.01% protein, 54.09% crude fibre, 0.15% essential oil and 1.14% fatty oil for hot extract and 0.23% for cold extract on the dried basis. The palmitic (33.81 & 31.58%) and linoleic acid (30.03 & 23.79%) were the major saturated and unsaturated fatty acids in the cold and hot extracted root powder respectively. Ca (23,600 mg/kg), Mg (7620.33 mg/kg) and K (1286.15 mg/kg) were the most predominant elements followed by Ni (1187.30 mg/kg), Se (913.79 mg/kg), Li (317.84 mg/kg), Na (288.72 mg/kg) and Fe (206.88 mg/kg). The toxic elements were found to be within the permissible limit. Glutamic acid (19.37%), glycine (14.53%) and lysine (17.08%) were found as the major amino acids. The decomposition rates were obtained by TG, DTG and DTA curve of the powder sample at various temperature ranges. The results demonstrated that the root part of Anethum sowa L. is a rich source of mineral elements, essential amino acid and fatty acids. The essential oil is the highly potential as bioactive oil for pharmaceuticals and medical applications, possessing antioxidant, antimicrobial and cytotoxic activities. The thermal analysis suggested as a simple, effective and rapid method to characterize the Anethum sowa L. species as well as to assess for herbal formulation.

Phosphate and sulfate are essential macro-elements for plant growth and development, and deficiencies in these mineral elements alter many metabolic functions. Nutritional constraints are not restricted to macro-elements. Essential metals such as zinc and iron have their homeostasis strictly genetically controlled, and deficiency or excess of these micro-elements can generate major physiological disorders, also impacting plant growth and development. Phosphate and sulfate on one hand, and zinc and iron on the other hand, are known to interact. These interactions have been partly described at the molecular and physiological levels, and are reviewed here. Furthermore the two macro-elements phosphate and sulfate not only interact between themselves but also influence zinc and iron nutrition. These intricated nutritional cross-talks are presented. The responses of plants to phosphorus, sulfur, zinc, or iron deficiencies have been widely studied considering each element separately, and some molecular actors of these regulations have been characterized in detail. Although some scarce reports have started to examine the interaction of these mineral elements two by two, a more complex analysis of the interactions and cross-talks between the signaling pathways integrating the homeostasis of these various elements is still lacking. However, a MYB-like transcription factor, PHOSPHATE STARVATION RESPONSE 1, emerges as a common regulator of phosphate, sulfate, zinc, and iron homeostasis, and its role as a potential general integrator for the control of mineral nutrition is discussed.

The concentrations of Cr, Cu, Fe, Mn, Ni, Pb, Cd, and Zn were determined in the brain, heart, liver, gill, gonad, spleen, kidney, and red and white muscles of Liza saliens (leaping mullet). Trace element levels in fish samples were analyzed by flame atomic absorption spectrometry. Among the non-essential metals, the levels of Ni and Pb in the tissues were higher than limits for fish proposed by FAO/WHO, EU, and TFC. Generally, the levels of the non-essential metals were much higher than those of manganese in the red and white muscles. Fe distribution pattern in tissues was in order of spleen > liver > heart > gill > brain > kidney > gonad > red muscle > white muscle. Red muscle was not within the safe limits for human consumption because non-essential metal (Ni, Pb) contents were higher than standard limits.

Some considerations concerning the alchemy of the De anima in arte alchemiae of pseudo-Avicenna.

This article explains some essential features of the alchemical doctrine of the De anima in arte alchemiae, a treatise written in Spain during the twelfth century (in Arabic, but only the Latin translation remains), and wrongly attributed to Avicenna. It shows that pseudo-Avicenna uses alchemical principles and elixir theory directly inspired by Jabirian texts, and classification of materials influenced by al-Razi. The alchemy of pseudo-Avicenna is entirely based on operations on the four elements: the alchemist has to reduce hair, blood or eggs to their elements, and isolate one of their essential properties (warmth, coldness, moisture and dryness), so that he can change the proportion of essential properties of the body he wants to transmute into gold or silver. The preparation made from hair, blood or eggs (the isolated property) is what he calls the elixir.

This article-the Romanell Report-offers an analysis of the current state of medical ethics education in the United States, focusing in particular on its essential role in cultivating professionalism among medical learners. Education in ethics has become an integral part of medical education and training over the past three decades and has received particular attention in recent years because of the increasing emphasis placed on professional formation by accrediting bodies such as the Liaison Committee on Medical Education and the Accreditation Council for Graduate Medical Education. Yet, despite the development of standards, milestones, and competencies related to professionalism, there is no consensus about the specific goals of medical ethics education, the essential knowledge and skills expected of learners, the best pedagogical methods and processes for implementation, and optimal strategies for assessment. Moreover, the quality, extent, and focus of medical ethics instruction vary, particularly at the graduate medical education level. Although variation in methods of instruction and assessment may be appropriate, ultimately medical ethics education must address the overarching articulated expectations of the major accrediting organizations. With the aim of aiding medical ethics educators in meeting these expectations, the Romanell Report describes current practices in ethics education and offers guidance in several areas: educational goals and objectives, teaching methods, assessment strategies, and other challenges and opportunities (including course structure and faculty development). The report concludes by proposing an agenda for future research.
