    As called for in the March 24, 2010, Memorandum of Understanding (MOU) for Hydropower, the U.S. Department of Energy (DOE), the U.S. Department of the Interior (DOI), the U.S. Army Corps of Engineers (USACE), environmental stakeholders, and the hydropower industry are collaborating to identify opportunities to simultaneously increase electricity generation and improve environmental services in river basins of the United States. New analytical tools provide an improved ability to understand, model, and visualize environmental and hydropower systems. Efficiencies and opportunities that might not be apparent in site-by-site analyses can be revealed through assessments at the river-basin scale. Information from basin-scale assessments could lead to better coordination of existing hydropower projects, or to inform siting decisions (e.g., balancing the removal of some dams with the construction of others), in order to meet renewable energy production and environmental goals. Basin-scale opportunity assessments would inform energy and environmental planning and address the cumulative effects of hydropower development and operations on river basin environmental quality in a way that quantifies energy-environment tradeoffs. Opportunity assessments would create information products, develop scenarios, and identify specific actions that agencies, developers, and stakeholders can take to locate new sustainable hydropower projects, increase the efficiency and environmental performance of existing projects, and restore and protect environmental quality in our nation's river basins. Government agencies and non-governmental organizations (NGO) have done significant work to understand and assess opportunities for both hydropower and environmental protection at the basin scale. Some initiatives have been successful, others less so, and there is a need to better understand the legacy of work on which this current project can build. This background literature review is intended

  5. Pain assessment and management in surgical nursing: a literature review.

    Science.gov (United States)

    Bell, Liz; Duffy, Anita

    Although postoperative pain assessment and management is an integral part of surgical nursing practice, it remains ad hoc despite numerous costly empirical research studies. Patients have a right to pain relief; however, the barriers to assessing and managing patient pain in practice have not as yet been overcome. A literature review to establish the main barriers to effective postoperative pain relief in clinical practice was carried out. The findings suggest that time management, and attitudes and beliefs of both patients and nurses are significant factors hampering practice. The authors conclude that future research in this area is futile, and suggest that nurses should focus on auditing their own practice to improve the effectiveness of pain management in practice and enhance standards of care.

    Assessment in the mental health area is a mechanism able to generate information that positively helps decision-making. Therefore, it is necessary to appropriate on the existing discussions, reasoning the challenges and possibilities linked to knowledge production within this scientific filed. A systematic review of publications about the Brazilian scientific production on mental health service assessment was performed, identifying and discussing methods, assessment perspectives and results. The search for articles was done in IBECS, Lilacs and Scielo databases, considering the publication of Federal Law 10.216. Thirty-five articles were selected based on the used terms and on the inclusion and exclusion criteria. Scientific production in this field is concentrated in the South and Southwest regions and holds different scopes and participants. Such wide range of possibilities is adopted as a way to help improving services and decision-making processes in mental health care. Advances in humanized, participative and community care are highlighted, but requiring more investments, professional qualification and organizational improvements. It is postulated greater integration among research, with evaluations going beyond structural aspects and the comparison with hospitalocentric models. PMID:26465864

    The aim of this review was to examine health literature on the reliability and validity of the Waterlow pressure sore assessment scale. A systematic review of published studies relating to the topic was conducted and literature was examined for its relevancy to the topic under investigation. Findings suggest that despite the availability of over 40 assessment tools, the Waterlow assessment scale is the most frequently used by health care staff. Research suggests that the Waterlow Scale is an unreliable method of assessing individuals at risk of pressure sore development with all studies indicating a poor interrater reliability status. Its validity has also been criticized because of its high-sensitivity but low-specificity levels.

    Santero, Nicholas; Masanet, Eric; Horvath, Arpad

    2010-04-20

    This report provides a critical review of existing literature and modeling tools related to life-cycle assessment (LCA) applied to pavements. The review finds that pavement LCA is an expanding but still limited research topic in the literature, and that the existing body of work exhibits methodological deficiencies and incompatibilities that serve as barriers to the widespread utilization of LCA by pavement engineers and policy makers. This review identifies five key issues in the current body of work: inconsistent functional units, improper system boundaries, imbalanced data for asphalt and cement, use of limited inventory and impact assessment categories, and poor overall utility. This review also identifies common data and modeling gaps in pavement LCAs that should be addressed in future work. These gaps include: the use phase (rolling resistance, albedo, carbonation, lighting, leachate, and tire wear and emissions), asphalt fumes, feedstock energy of bitumen, traffic delay, the maintenance phase, and the end-of-life phase. This review concludes with a comprehensive list of recommendations for future research, which shed light on where improvements in knowledge can be made that will benefit the accuracy and comprehensiveness of pavement LCAs moving forward.

  1. The Strategic Environment Assessment bibliographic network: A quantitative literature review analysis

    International Nuclear Information System (INIS)

    Academic literature has been continuously growing at such a pace that it can be difficult to follow the progression of scientific achievements; hence, the need to dispose of quantitative knowledge support systems to analyze the literature of a subject. In this article we utilize network analysis tools to build a literature review of scientific documents published in the multidisciplinary field of Strategic Environment Assessment (SEA). The proposed approach helps researchers to build unbiased and comprehensive literature reviews. We collect information on 7662 SEA publications and build the SEA Bibliographic Network (SEABN) employing the basic idea that two publications are interconnected if one cites the other. We apply network analysis at macroscopic (network architecture), mesoscopic (sub graph) and microscopic levels (node) in order to i) verify what network structure characterizes the SEA literature, ii) identify the authors, disciplines and journals that are contributing to the international discussion on SEA, and iii) scrutinize the most cited and important publications in the field. Results show that the SEA is a multidisciplinary subject; the SEABN belongs to the class of real small world networks with a dominance of publications in Environmental studies over a total of 12 scientific sectors. Christopher Wood, Olivia Bina, Matthew Cashmore, and Andrew Jordan are found to be the leading authors while Environmental Impact Assessment Review is by far the scientific journal with the highest number of publications in SEA studies. - Highlights: • We utilize network analysis to analyze scientific documents in the SEA field. • We build the SEA Bibliographic Network (SEABN) of 7662 publications. • We apply network analysis at macroscopic, mesoscopic and microscopic network levels. • We identify SEABN architecture, relevant publications, authors, subjects and journals

    2016-01-01

    A scoping review was conducted to map existing evidence on strategies to measure male and female intimate partner violence (IPV). PubMed, ISI Web of Knowledge, and Scopus databases were searched from inception to 2014. There were 1,098 studies analyzed. To assess IPV, the most commonly followed strategy was the creation of study-specific questions (30.3%). The Conflict Tactics Scales (CTS) were the most frequent choice among generic instruments, whereas for clinical samples, the preferred tool was the Abuse Assessment Screen. Prevalence estimates were generally higher when the original versions of the CTS were used. This review provides a guiding frame of what exists in the IPV measurement literature, showing trends in the choice for a particular instrument according to administration methods and settings.

    Truett, L.F.

    2003-12-10

    The purpose of the Hydrogen, Fuel Cells, and Infrastructure Technologies (HFCIT) Program Baseline Knowledge Assessment is to measure the current level of awareness and understanding of hydrogen and fuel cell technologies and the hydrogen economy. This information will be an asset to the HFCIT program in formulating an overall education plan. It will also provide a baseline for comparison with future knowledge and opinion surveys. To assess the current understanding and establish the baseline, the HFCIT program plans to conduct scientific surveys of four target audience groups--the general public, the educational community, governmental agencies, and potential large users. The purpose of the literature review is to examine the literature and summarize the results of surveys that have been conducted in the recent past concerning the existing knowledge and attitudes toward hydrogen. This literature review covers both scientific and, to a lesser extent, non-scientific polls. Seven primary data sources were reviewed, two of which were studies based in Europe. Studies involved both closed-end and open-end questions; surveys varied in length from three questions to multi-page interviews. Populations involved in the studies were primarily adults, although one study involved students. The number of participants ranged from 13 to over 16,000 per study. In addition to the primary surveys, additional related studies were mined for pertinent information. The primary conclusions of the surveys reviewed are that the public knows very little about hydrogen and fuel cell technologies but is generally accepting of the potential for hydrogen use. In general, respondents consider themselves as environmentally conscious. The public considers safety as the primary issue surrounding hydrogen as a fuel. Price, performance, and convenience are also considerations that will have major impacts on purchase decisions.

  5. Text mining for literature review and knowledge discovery in cancer risk assessment and research.

    Directory of Open Access Journals (Sweden)

    Anna Korhonen

    Full Text Available Research in biomedical text mining is starting to produce technology which can make information in biomedical literature more accessible for bio-scientists. One of the current challenges is to integrate and refine this technology to support real-life scientific tasks in biomedicine, and to evaluate its usefulness in the context of such tasks. We describe CRAB - a fully integrated text mining tool designed to support chemical health risk assessment. This task is complex and time-consuming, requiring a thorough review of existing scientific data on a particular chemical. Covering human, animal, cellular and other mechanistic data from various fields of biomedicine, this is highly varied and therefore difficult to harvest from literature databases via manual means. Our tool automates the process by extracting relevant scientific data in published literature and classifying it according to multiple qualitative dimensions. Developed in close collaboration with risk assessors, the tool allows navigating the classified dataset in various ways and sharing the data with other users. We present a direct and user-based evaluation which shows that the technology integrated in the tool is highly accurate, and report a number of case studies which demonstrate how the tool can be used to support scientific discovery in cancer risk assessment and research. Our work demonstrates the usefulness of a text mining pipeline in facilitating complex research tasks in biomedicine. We discuss further development and application of our technology to other types of chemical risk assessment in the future.

    Dengue vaccines are currently in development and policymakers need appropriate economic studies to determine their potential financial and public health impact. We searched five databases (PubMed, EMBASE, LILAC, EconLit, and WHOLIS) to identify health economics studies of dengue. Forty-three manuscripts were identified that provided primary data: 32 report economic burden of dengue and nine are comparative economic analyses assessing various interventions. The remaining two were a willingness-to-pay study and a policymaker survey. An expert panel reviewed the existing dengue economic literature and recommended future research to fill information gaps. Although dengue is an important vector-borne disease, the economic literature is relatively sparse and results have often been conflicting because of use of inconsistent assumptions. Health economic research specific to dengue is urgently needed to ensure informed decision making on the various options for controlling and preventing this disease. PMID:21363989

    Our current understanding of the etiology and maintenance of eating disorders and obesity continues to be far from complete. Similarly, our understanding of determinants of both successful and unsuccessful weight loss surgery is also quite limited. While a number of research methodologies have been applied to these areas, one methodology that has recently seen a rise in popularity is the use of ecological momentary assessment (EMA). EMA allows one to study a variety of variables of interest in the natural environment. The study of eating disorders, obesity, and bariatric surgery has all been conducted using EMA recently. The current study is a review of these areas and summarizes the recent literature (past 3 years) in eating disorders, obesity, and bariatric surgery using EMA methodology. PMID:26893235

    Full Text Available This review is a critical analysis regarding the study and utilization of the World Health Organization Disability Assessment Schedule II (WHODAS II as a basis for establishing specific criteria for evaluating relevant international scientific literature.The WHODAS II is an instrument developed by the World Health Organisation in order to assess behavioural limitations and restrictions related to an individual’s participation, independent from a medical diagnosis. This instrument was developed by the WHO’s Assessment, Classification and Epidemiology Group within the framework of the WHO/NIH Joint Project on Assessment and Classification of Disablements. To ascertain the international dissemination level of for WHODAS II’s utilization and, at the same time, analyse the studies regarding the psychometric validation of the WHODAS II translation and adaptation in other languages and geographical contests. Particularly, our goal is to highlight which psychometric features have been investigated, focusing on the factorial structure, the reliability, and the validity of this instrument. International literature was researched through the main data bases of indexed scientific production: the Cambridge Scientific Abstracts – CSA, PubMed, and Google Scholar, from 1990 through to December 2008.The following search terms were used:“whodas”, in the field query, plus “title” and “abstract”.The WHODAS II has been used in 54 studies, of which 51 articles are published in international journals, 2 conference abstracts, and one dissertation abstract. Nevertheless, only 7 articles are published in journals and conference proceedings regarding disability and rehabilitation. Others have been published in medical and psychiatric journals, with the aim of indentifying comorbidity correlations in clinical diagnosis concerning patients with mental illness.

    2005-05-01

    The aim of this review was to evaluate the methods of pain measurement in controlled clinical trials in oncology published between 1999 and 2002. An electronic literature search strategy was used according to established criteria applied to the Medline database and PubMed search engine. Articles were selected to include only studies that had chronic cancer pain as the primary or secondary objective of a controlled clinical trial. A specific evaluation scheme was used to examine how pain measurement methods were chosen and implemented in the study procedures. The search strategy identified 613 articles, and 68 were selected for evaluation. Most articles (69%) chose unidimensional pain measurement tools, such as visual analogue scales, numerical rating scales and verbal rating scales, whereas others used questionnaires. The implementation of the pain assessment method was problematic in many studies, especially as far as time frame of pain assessment (70%), administration modalities (46%), and use of non-validated measurement methods (10%). Design of study and data analysis were often unclear about the definition of pain outcome measure (40%), patient compliance with pain assessment (98%), and impact of missing data (56%). Statistical techniques were seldom appropriate to the type of data collected and often inadequate to describe the pain variable under study. It is clear from this review that most authors were aware of the need of valid pain measurement tools to be used in clinical trials. However, too often these tools were not appropriately used in the trial, or at least their use was not described with sufficient accuracy in the trial methods. PMID:15904753

  14. Safety assessment of GM plants: An updated review of the scientific literature.

    Science.gov (United States)

    Domingo, José L

    2016-09-01

    In a wide revision of the literature conducted in 2000, I noted that the information in scientific journals on the safety of genetically modified (GM) foods in general, and GM plants in particular, was scarce. Of course, it was not sufficient to guarantee that the consumption of these products should not mean risks for the health of the consumers. Because of the scientific interest in GM organisms (GMOs), as well as the great concern that the consumption of GM foods/plants has raised in a number of countries, I conducted two subsequent revisions (2007 and 2011) on the adverse/toxic effects of GM plants. In the present review, I have updated the information on the potential adverse health effects of GM plants consumed as food and/or feed. With only a few exceptions, the reported studies in the last six years show rather similar conclusions; that is to say, the assessed GM soybeans, rice, corn/maize and wheat would be as safe as the parental species of these plants. However, in spite of the notable increase in the available information, studies on the long-term health effects of GM plants, including tests of mutagenicity, teratogenicity and carcinogenicity seem to be still clearly necessary.

    2008-10-01

    The objective of this project was to provide initial estimates of the relationship between insecticide use on passenger aircraft and exposure levels present in the cabin environment. The work was initially divided into three tasks including 1) a review of insecticide application practices in commercial aircraft, 2) exploratory measurements of insecticide concentrations in treated aircraft and 3) screening level exposure modeling. Task 1 gathered information that is needed to assess the time-concentration history of insecticides in the airline cabin. The literature review focused on application practices, information about the cabin environment and existing measurements of exposure concentrations following treatment. Information from the airlines was not available for estimating insecticide application rates in the U.S. domestic fleet or for understanding how frequently equipment rotate into domestic routes following insecticide treatment. However, the World Health Organization (WHO) recommends several methods for treating aircraft with insecticide. Although there is evidence that these WHO guidelines may not always be followed, and that practices vary by airline, destination, and/or applicator company, the guidelines in combination with information related to other indoor environments provides a plausible basis for estimating insecticide loading rates on aircraft. The review also found that while measurements of exposure concentrations following simulated aerosol applications are available, measurements following residual treatment of aircraft or applications in domestic aircraft are lacking. Task 2 focused on developing an approach to monitor exposure concentrations in aircraft using a combination of active and passive sampling methods. An existing active sampling approach was intended to provide data immediately following treatment while a passive sampler was developed to provide wider coverage of the fleet over longer sampling periods. The passive sampler, based

  20. Literature review supporting assessment of potential radionuclides in the 291-Z exhaust ventilation

    International Nuclear Information System (INIS)

    This literature review was prepared to support a study conducted by Pacific Northwest Laboratory to assess the potential deposition and resuspension of radionuclides in the 291-Z ventilation exhaust building located in the 200 West Area of the US Department of Energy's Hanford Project near Richland, Washington. The filtered ventilation air from three of the facilities at the Plutonium Finishing Plant (PFP) complex are combined together in the 291-Z building before discharge through a common stack. These three facilities contributing filtered exhaust air to the discharge stream are (1) the PFP, also known as the Z-Plant or 234-5Z, (2) the Plutonium Reclamation Facility (PRF or 236-Z), and (3), the Waste Incinerator Building (WIB or 232-Z). The 291-Z building houses the exhaust fans that pull air from the 291-Z central collection plenum and exhausts the air to the stack. Section 2.0 of this report is a description of the physical characteristic of the ventilation system from the High Efficiency Particulate Air (HEPA) filters to the exhaust stack. A description of the processes performed in the facilities that are vented through 291-Z is given in Section 3.0. The description focuses on the chemical and physical forms of potential aerosols given off from the unit operations. A timeline of the operations and events that may have affected the deposition of material in the ventilation system is shown. Aerosol and radiation measurements taken in previous studies are also discussed. Section 4.0 discusses the factors that influence particle deposition and adhesion. Mechanisms of attachment and resuspension are covered with specific attention to the PFP ducts. Conclusions and recommendations are given in Section 5.0

    2011-03-15

    The purpose of this review is to evaluate the possibility of panoramic radiography as a national oral examination tool. This report was carried out by review of the literatures. Panoramic radiography has sufficient diagnostic accuracy in dental caries, periodontal diseases, and other lesions. Also, the effective dose of panoramic radiography is lower than traditional full-mouth periapical radiography. Panoramic radiography will improve the efficacy of dental examination in national oral examination. However, more studies are required to evaluate the benefit, financial cost, and operation time and also to make selection criteria and quality management program.

    Water is a growing concern in cities, and its sustainable management is very complex. Life cycle assessment (LCA) has been increasingly used to assess the environmental impacts of water technologies during the last 20 years. This review aims at compiling all LCA papers related to water technologies, out of which 18 LCA studies deals with whole urban water systems (UWS). A focus is carried out on these 18 case studies which are analyzed according to criteria derived from the four phases of LCA international standards. The results show that whereas the case studies share a common goal, i.e., providing quantitative information to policy makers on the environmental impacts of urban water systems and their forecasting scenarios, they are based on different scopes, resulting in the selection of different functional units and system boundaries. A quantitative comparison of life cycle inventory and life cycle impact assessment data is provided, and the results are discussed. It shows the superiority of information offered by multi-criteria approaches for decision making compared to that derived from mono-criterion. From this review, recommendations on the way to conduct the environmental assessment of urban water systems are given, e.g., the need to provide consistent mass balances in terms of emissions and water flows. Remaining challenges for urban water system LCAs are identified, such as a better consideration of water users and resources and the inclusion of recent LCA developments (territorial approaches and water-related impacts).

    Patients' symptoms have a place of prominence in the rheumatology landscape, and among them pain is the most conspicuous. Several pain assessment tools have been validated. One-dimensional pain scales such as visual analog scales (VASs) and numeric rating scales (NRSs) are fast to administer but have limitations that must be acknowledged. Some clinical situations require the use of multidimensional scales such as the McGill Pain Questionnaire or the Multidimensional Pain Inventory (MPI). These tools allow the assessment and management of the diverse components of pain. Here, we review the main patient-reported outcomes that can serve to evaluate pain and the psychometric properties of pain assessment tools. We also discuss the selection of the tool most appropriate for each situation (e.g., everyday practice and research). PMID:26898486

    2011-05-01

    In recent years, there has been a notable concern on the safety of genetically modified (GM) foods/plants, an important and complex area of research, which demands rigorous standards. Diverse groups including consumers and environmental Non Governmental Organizations (NGO) have suggested that all GM foods/plants should be subjected to long-term animal feeding studies before approval for human consumption. In 2000 and 2006, we reviewed the information published in international scientific journals, noting that the number of references concerning human and animal toxicological/health risks studies on GM foods/plants was very limited. The main goal of the present review was to assess the current state-of-the-art regarding the potential adverse effects/safety assessment of GM plants for human consumption. The number of citations found in databases (PubMed and Scopus) has dramatically increased since 2006. However, new information on products such as potatoes, cucumber, peas or tomatoes, among others was not available. Corn/maize, rice, and soybeans were included in the present review. An equilibrium in the number research groups suggesting, on the basis of their studies, that a number of varieties of GM products (mainly maize and soybeans) are as safe and nutritious as the respective conventional non-GM plant, and those raising still serious concerns, was currently observed. Nevertheless, it should be noted that most of these studies have been conducted by biotechnology companies responsible of commercializing these GM plants. These findings suggest a notable advance in comparison with the lack of studies published in recent years in scientific journals by those companies. All this recent information is herein critically reviewed. PMID:21296423

    2011-01-01

    As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical

  18. Neuroimaging assessment of cerebrovascular reactivity in concussion: current concepts, methodological considerations and review of the literature

    Directory of Open Access Journals (Sweden)

    Michael John Ellis

    2016-04-01

    Full Text Available Concussion is a form of traumatic brain injury (TBI that presents with a wide spectrum of subjective symptoms and few objective clinical findings. Emerging research suggests that one of the processes that may contribute to concussion pathophysiology is dysregulation of cerebral blood flow (CBF leading to a mismatch between CBF delivery and the metabolic needs of the injured brain. Cerebrovascular reactivity (CVR is defined as the change in CBF in response to a measured vasoactive stimulus. Several magnetic resonance imaging (MRI techniques can be used as a surrogate measure of CBF in clinical and laboratory studies. In order to provide an accurate assessment of CVR, these sequences must be combined with a reliable, reproducible vasoactive stimulus that can manipulate CBF. Although CVR imaging currently plays a crucial role in the diagnosis and management of many cerebrovascular diseases, only recently have studies begun to apply this assessment tool in patients with concussion. In order to evaluate the quality, reliability and relevance of CVR studies in concussion, it is important that clinicians and researchers have a strong foundational understanding of the role of cerebral blood flow regulation in health, concussion and more severe forms of TBI, and an awareness of the advantages and limitations of currently available CVR measurement techniques. Accordingly, in this review we 1 discuss the role of CVR in TBI and concussion; 2 examine methodological considerations for MRI-based measurement of CVR; and 3 provide an overview of published CVR studies in concussion patients.

  19. An assessment of the effectiveness of magnetic resonance imaging of the shoulder: literature review

    International Nuclear Information System (INIS)

    Objective. To analyse and compare all papers published to date (August 2000) that quantify the effectiveness, defined as the impact of clinician's diagnosis or management plans, or patient outcome, of MRI of the shoulder.Design. A computerised search of Index Medicus with a broad search strategy relating to shoulder MRI was performed. Manual assessment of all papers listed was undertaken with classification of each paper depending on whether it addressed questions of (1) technical performance, (2) diagnostic performance or (3) outcome.Results. Four of 265 qualifying papers addressed aspects of effectiveness and these were reviewed. The impact on the clinician's diagnosis varied widely between papers: the primary diagnosis was altered in 23% to 68% of cases, and the management plans were subsequently changed in 15% to 61% of cases. Only one paper addressed the impact on patient health.Conclusions. The effectiveness of MRI of the shoulder depends on the clinical skills of the referring clinician and prevalence of disease in the study population. This will have implications when the effectiveness of an imaging technique between different institutions is compared, and this in turn will influence any comparisons of cost-effectiveness. (orig.)

    2011-03-01

    Full Text Available Abstract Background Participatory Research (PR entails the co-governance of research by academic researchers and end-users. End-users are those who are affected by issues under study (e.g., community groups or populations affected by illness, or those positioned to act on the knowledge generated by research (e.g., clinicians, community leaders, health managers, patients, and policy makers. Systematic reviews assessing the generalizable benefits of PR must address: the diversity of research topics, methods, and intervention designs that involve a PR approach; varying degrees of end-user involvement in research co-governance, both within and between projects; and the complexity of outcomes arising from long-term partnerships. Methods We addressed the above mentioned challenges by adapting realist review methodology to PR assessment, specifically by developing inductively-driven identification, selection, appraisal, and synthesis procedures. This approach allowed us to address the non-uniformity and complexity of the PR literature. Each stage of the review involved two independent reviewers and followed a reproducible, systematic coding and retention procedure. Retained studies were completed participatory health interventions, demonstrated high levels of participation by non-academic stakeholders (i.e., excluding studies in which end-users were not involved in co-governing throughout the stages of research and contained detailed descriptions of the participatory process and context. Retained sets are being mapped and analyzed using realist review methods. Results The librarian-guided search string yielded 7,167 citations. A total of 594 citations were retained after the identification process. Eighty-three papers remained after selection. Principle Investigators (PIs were contacted to solicit all companion papers. Twenty-three sets of papers (23 PR studies, comprising 276 publications, passed appraisal and are being synthesized using realist

There is little information to assist primary care providers to choose or deliver relevant, efficient, and soundly constructed assessment instruments for this purpose.Objective: We recently published the findings of a literature review, which produced a compendium of assessment instruments to identify adults with, or at-risk of developing, persistent pain of noncancer origin. This paper reports on instruments opportunistically identified during this review which may be appropriate to primary health care settings for early identification of such patients.Results: One hundred sixteen potentially useful instruments were initially identified in the review, measuring pain severity, psychological distress, functional capacity, quality of life or multidimensional constructs of persistent pain. Following a series of steps, 45 instruments were shortlisted, with sound clinical utility and strong psychometric properties. Of these, 16 instruments were appropriate to primary health care settings because of simple wording, brief items, short administration time, and ease of scoring.Conclusion: No one assessment instrument captured all constructs of persistent pain. The 16 instruments provide a broad choice for primary care clinicians to assist with early identification of adults at risk of, or with persistent pain.Keywords: adults with persistent pain, primary health care assessment, early identification

    Monetary valuation, or monetarisation, is the determination of the economic value of non-market goods, i.e. goods for which no market exists. Although monetary valuation has a great potential to be applied in Life Cycle Assessment (LCA), in particular in the weighting phase, several challenges limit its diffusion in the field, which resulted in only a few applications so far. This study evaluated different methods for monetary valuation with respect to their relevance in LCA. The specific obj...

    2015-09-01

    FederAnziani Senior Italia and SIU - Italian Society of Urology - have decided to work together to draft a document focussing on Benign Prostatic Hyperplasia (BPH), and to stress the importance of adherence with pharmacological treatment in this setting, from both a scientific and a patient standpoint. Starting from a literature search, the two associations analysed to what extent an increase in treatment adherence amongst these patients influences hospital savings and to what extent therapy persistence levels are affected by monotherapy rather than free drug combinations. These estimates were performed only on patients taking medicinal products belonging to the 5 α-reductase inhibitors (5ARI) class that, although not indispensable, are the compounds that bring the greatest benefits, especially in the elderly and for which we know that every additional 30 days of therapy reduced the likelihood of acute urinary retention (AUR) and surgery by 14% and 11% respectively *. The results show that the use of fixed combination therapy would involve an increase in persistence due to the lower rate of patients abandoning treatment over time. Each 30 day-increment of 5ARI therapy, i.e. for an expenditure of 10.6 million euros extra per year for 5ARI medication, savings of approximately 24.3 million euros in hospital costs could be achieved.

    Metzler, H; Metzler, C

    1998-01-01

    Several hundred written sources have been researched regarding old and new findings. Forgotten and new facts are covered in four chapters. One of the authors is a retired industrial chemist, and the other a dental surgeon. In the first section the natural and synthetic sources of mercury are explained. In every scientific study the ubiquity of mercury for billions of years must be taken into consideration. The second chapter looks at the toxicology of mercury and its compounds. Well known catastrophies in Japan and Iraq are depicted. Individual intoxications are hardly mentioned in literature. The third chapter is devoted to the dental amalgam, a silver alloy with both physical-chemical properties, and corrosive and thermal behaviour. An attempt is made to define the mercury balance. The forth paragraph deals with the disposal and recycling of mercury. Many dental associations are currently discussing the possibility of recycling amalgam, which is rather a stable silver alloy than a volatile mercury compound. A controlled landfill disposal of dental amalgam will absorb a certain quantity of mercury during its life cycle, and is positive. Recycling is expensive, energy consuming and causes additional exposure. Unless silver and mercury become rare metals, recycling should not be considered. As yet no worldwide regulatory procedures exist. PMID:9741247

  14. Literature review and assessment of various approaches to bioremediation of oil and associated hydrocarbons in soil and groundwater

    International Nuclear Information System (INIS)

    A study was conducted of available techniques for the biological treatment of oil and associated hydrocarbon contamination in soil and groundwater. The study involved a detailed literature search and review, as well as discussions with the users and developers of a number of the bioremediation techniques assessed. The result is a compendium of selected state-of-the-art bioremediation technologies which can serve to guide the selection process for treatment technology for a particular site subject to remediation. Background is provided on the various classes of sites on which petroleum-related contamination could occur, and the nature of contaminants typical of such sites. The mechanisms of hydrocarbon biodegradation are outlined along with various approaches to bioremediation such as in-situ, on-site, bioreactors, landfarming, composting, and physical/chemical treatments. Field trials required to characterize the site and provide an indication of the suitability of bioremediation and the most appropriate bioremediation approach are described. Commercially available bioremediation technologies are briefly discussed. A number of the bioremedial techniques reviewed are compared to more conventional treatment processes in terms of such criteria as operating cost, effectiveness, advantages, risks, applicability, equipment and manpower requirements, and considerations regarding usage in Canadian conditions. 15 figs., 17 tabs

    A glass melter for use in processing radioactive waste is a challenging environment for the materials of construction (MOC) resulting from a combination of high temperatures, chemical attack, and erosion/corrosion; therefore, highly engineered materials must be selected for this application. The focus of this report is to review the testing and evaluations used in the selection of the Defense Waste Processing Facility (DWPF), glass contact MOC specifically the Monofrax® K-3 refractory and Inconel® 690 alloy. The degradation or corrosion mechanisms of these materials during pilot scale testing and in-service operation were analyzed over a range of oxidizing and reducing flowsheets; however, DWPF has primarily processed a reducing flowsheet (i.e., Fe2+/ΣFe of 0.09 to 0.33) since the start of radioactive operations. This report also discusses the materials selection for the DWPF off-gas system and the corrosion evaluation of these materials during pilot scale testing and non-radioactive operations of DWPF Melter #1. Inspection of the off-gas components has not been performed during radioactive operations with the exception of maintenance because of plugging.

    Portal hypertension (PH) is one of the most important causes of morbidity and mortality in patients with chronic liver disease. PH measurement is crucial to stage and predict the clinical outcome of liver cirrhosis. Measurement of hepatic vein pressure gradient is considered the gold standard for assessment of the degree of PH; however, it is an invasive method and has not been used widely. Thus, noninvasive methods have been proposed recently. We critically evaluated serum markers, abdominal ultrasonography, and particularly liver and spleen stiffness measurement, which represent the more promising methods to stage PH degree and to assess the presence/absence of esophageal varices (EV). A literature search was carried out on MEDLINE, EMBASE, Web of Science, and Scopus for articles and abstracts. The search terms used included 'liver cirrhosis', 'portal hypertension', 'liver stiffness', 'spleen stiffness', 'ultrasonography', and 'portal hypertension serum biomarker'. The articles cited were selected on the basis of their relevance to the objective of the review. The results of available studies indicate that individually, these methods have a mild accuracy in predicting the presence of EV, and thus they cannot substitute endoscopy to predict EV. When these tests were used in combination, their accuracy increased. In addition to the PH staging, several serum markers and spleen stiffness measurement can predict the clinical outcome of liver cirrhosis with a good accuracy, comparable to that of hepatic vein pressure gradient. In the future, noninvasive methods could be used to select patients requiring further investigations to identify the best tailored clinical management. PMID:26020376

    Individuals following vegetarian diets are at risk for developing vitamin B12 deficiency owing to suboptimal intake. As vitamin B12 is essential for the synthesis of nucleic acids, erythrocytes and in the maintenance of myelin, deficiency may result in a variety of symptoms. Some of these symptoms may be severe while others may be irreversible. The objective of this review was to assess vitamin B12 deficiency, based on reported serum vitamin B12, among individuals adhering to different types of vegetarian diets. A systematic literature search was carried out using multiple search engines including PubMed, Medline, CINAHL plus, ERIC, Nursing and Allied Health Collection and Nursing/Academic Edition. The inclusion criteria consisted of original studies that assessed serum vitamin B12, studies written in English, non-case studies and studies that reported actual percentages of vitamin B12 deficiency. Forty research studies were included. The deficiency prevalence among infants reached 45%. The deficiency among the children and adolescents ranged from 0 to 33.3%. Deficiency among pregnant women ranged from 17 to 39%, dependent on the trimester. Adults and elderly individuals had a deficiency range of 0-86.5%. Higher deficiency prevalence was reported in vegans than in other vegetarians. Thus, with few exceptions, the reviewed studies documented relatively high deficiency prevalence among vegetarians. Vegans who do not ingest vitamin B12 supplements were found to be at especially high risk. Vegetarians, especially vegans, should give strong consideration to the use of vitamin B12 supplements to ensure adequate vitamin B12 intake. Vegetarians, regardless of the type of vegetarian diet they adhere to, should be screened for vitamin B12 deficiency. PMID:24667752

  20. Fissure minerals, literature review

    International Nuclear Information System (INIS)

    This paper is a review of methods used for direct and indirect dating of tectonic events. Isotope geochemistry including stable isotopes as well as fission track- dating, fluid inclusion and thermoluminescens techniques have been considered. It has been concluded that an investigation of tectonic (and thermal) events should start with a detailed study of the mineral phases grown in seald fissures as well as minerals from fissure walls. This study should include phase identification, textures as well as mineral chemistry. The information from this study is fundamental for the decision of further investigations. Mineral chemistry including isotopes and fluid inclusion studies will give an essential knowledge about crystallization conditions for fissure minerals concerned. Direct dating using fission tracks as well as radioactive isotopes could be useful for some minerals. Application of thermoluminescens dating on fissure minerals is doubtful. (Auth.)

    2016-02-01

    Full Text Available ABSTRACT INTRODUCTION: There is a controversy concerning the terminology and definition of rhinitis in pregnancy. Gestational rhinitis is a relatively common condition, which has drawn increasing interest in recent years due to a possible association with maternal obstructive sleep apnea syndrome (OSAS and unfavorable fetal outcomes. OBJECTIVE: To review the current knowledge on gestacional rhinitis, and to assess its evidence. METHODS: Structured literature search. RESULTS: Gestational rhinitis and rhinitis "during pregnancy" are somewhat similar conditions regarding their physiopathology and treatment, but differ regarding definition and prognosis. Hormonal changes have a presumed etiological role, but knowledge about the physiopathology of gestational rhinitis is still lacking. Management of rhinitis during pregnancy focuses on the minimal intervention required for symptom relief. CONCLUSION: As it has a great impact on maternal quality of life, both the otorhinolaryngologist and the obstetrician must be careful concerning the early diagnosis and treatment of gestational rhinitis, considering the safety of treatment measures and drugs and their current level of evidence.

    2012-05-11

    Concrete containment structures and cement-based fills and waste forms are used at the Savannah River Site to enhance the performance of shallow land disposal systems designed for containment of low-level radioactive waste. Understanding and measuring transport through cracked concrete is important for describing the initial condition of radioactive waste containment structures at the Savannah River Site (SRS) and for predicting performance of these structures over time. This report transmits the results of a literature review on transport through cracked concrete which was performed by Professor Jason Weiss, Purdue University per SRR0000678 (RFP-RQ00001029-WY). This review complements the NRC-sponsored literature review and assessment of factors relevant to performance of grouted systems for radioactive waste disposal. This review was performed by The Center for Nuclear Waste Regulatory Analyses, San Antonio, TX, and The University of Aberdeen, Aberdeen Scotland and was focused on tank closure. The objective of the literature review on transport through cracked concrete was to identify information in the open literature which can be applied to SRS transport models for cementitious containment structures, fills, and waste forms. In addition, the literature review was intended to: (1) Provide a framework for describing and classifying cracks in containment structures and cementitious materials used in radioactive waste disposal, (2) Document the state of knowledge and research related to transport through cracks in concrete for various exposure conditions, (3) Provide information or methodology for answering several specific questions related to cracking and transport in concrete, and (4) Provide information that can be used to design experiments on transport through cracked samples and actual structures.

    Full Text Available Recent fraud scandals involving highly known corporations like Enron, WorldCom, and Xerox have eroded public confidence in financial reporting. At the same time, the auditing profession has suffered a big hit. In this scenario, Continuous Auditing (CA seems to have emerged as a response to recover the credibility of the auditing profession as well as meeting Sarbanes-Oxley (SOX requirements. This study, that adopts an exploratory approach, analyzes the existing literature on this topic. First, we address the concepts, models and implications of CA. After, throughout a search on the journals indexed at the CAPES's Basis, a literature review is conducted. A total of 57 articles were selected. We analyze authorship, affiliation, publications, year and type of research of papers that have addressed CA. Findings evidence that most articles addressing CA are non-empirical and adopt a conceptual approach. Also, there is an increasing tendency of continuous auditing studies. Rutgers University seems to be the World's leading research center on CA. This study aims to contribute to the Accounting Science by evidencing possibilities for research and publication in CA.

    Hays, Jake; Shonkoff, Seth B. C.

    2016-01-01

    The body of science evaluating the potential impacts of unconventional natural gas development (UNGD) has grown significantly in recent years, although many data gaps remain. Still, a broad empirical understanding of the impacts is beginning to emerge amidst a swell of research. The present categorical assessment provides an overview of the peer-reviewed scientific literature from 2009–2015 as it relates to the potential impacts of UNGD on public health, water quality, and air quality. We have categorized all available original research during this time period in an attempt to understand the weight and direction of the scientific literature. Our results indicate that at least 685 papers have been published in peer-reviewed scientific journals that are relevant to assessing the impacts of UNGD. 84% of public health studies contain findings that indicate public health hazards, elevated risks, or adverse health outcomes; 69% of water quality studies contain findings that indicate potential, positive association, or actual incidence of water contamination; and 87% of air quality studies contain findings that indicate elevated air pollutant emissions and/or atmospheric concentrations. This paper demonstrates that the weight of the findings in the scientific literature indicates hazards and elevated risks to human health as well as possible adverse health outcomes associated with UNGD. There are limitations to this type of assessment and it is only intended to provide a snapshot of the scientific knowledge based on the available literature. However, this work can be used to identify themes that lie in or across studies, to prioritize future research, and to provide an empirical foundation for policy decisions. PMID:27096432

    Fullerenes have gained considerable attention due to their anti-oxidant and radical scavenging properties. Their current applications include targeted drug delivery, energy application, polymer modifications and cosmetic products. The production of fullerenes and their use in consumer products is expected to increase in future. This study aims to investigate the feasibility and challenges associated with conducting a human health risk assessment for fullerenes based on the open literature, utilising an approach similar to that of a classical regulatory risk assessment. Available data relates to different types of fullerenes (with varying size, surface chemistry, solubility, aggregation/agglomeration) and care should therefore be taken when drawing general conclusions across the parameters. Pristine fullerenes have shown low toxicity and there is probably no risks expected for humans exposed to fullerenes in the workplace under good hygiene conditions. The main concern for consumers is exposure via direct dermal application of fullerenes present in cosmetics. Available studies do not indicate a short term risk from the tested fullerene types, however no extrapolation to all fullerene types and to chronic exposure can be made. In conclusion, the current dataset on fullerenes in relation to both, human exposure and hazard is limited and does not allow reaching any definite conclusions suitable for regulatory decision making. Main future work should focus on generating occupational and consumer exposure data, as well as suitable data on toxicokinetics and potential toxic effects following repeated inhalation and dermal exposure allowing to determine a NOAEL. It seems also relevant to clarify whether certain fullerene types may potentially induce genotoxic and/or carcinogenic effects via physiologically relevant routes. PMID:20800639

    Full Text Available Abstract Background Safe and timely access to effective and appropriate medication through primary care settings is a major concern for all countries addressing both acute and chronic disease burdens. Legislation for nurses and other professionals allied to medicine to prescribe exists in a minority of countries, with more considering introducing legislation. Although there is variation in the range of medicines permitted to be prescribed, questions remain as to the contribution prescribing by nurses and professionals allied to medicine makes to the care of patients in primary care and what is the evidence on which clinicians, commissioners of services and policy makers can consider this innovation. Methods A integrative review of literature on non-medical prescribing in primary care was undertaken guided by dimensions of health care quality: effectiveness, acceptability, efficiency and access. Results 19 papers of 17 empirical studies were identified which provided evidence of patient outcome of non medical prescribing in primary care settings. The majority were undertaken in the UK with only one each from the USA, Canada, Botswana and Zimbabwe. Only two studies investigated clinical outcomes of non-medical prescribing. Seven papers reported on qualitative designs and four of these had fewer than ten participants. Most studies reported that non medical prescribing was widely accepted and viewed positively by patients and professionals. Conclusions Primary health care is the setting where timely access to safe and appropriate medicines is most critical for the well-being of any population. The gradual growth over time of legislative authority and in the numbers of non-medical prescribers, particularly nurses, in some countries suggests that the acceptability of non-medical prescribing is based on the perceived value to the health care system as a whole. Our review suggests that there are substantial gaps in the knowledge base to help evidence

    Teixeira, Larissa Lane Cardoso

    2011-10-01

    Full Text Available Introduction: Tourette Syndrome (TS was described for the first time in 1825, and it is a neuropsychiatry disease, initially begins in childhood, affects more males, characterized by remarkable social and psychological commitment, impacting the lives of patients and family. Until recently, this disease were considered a rare condition, but current studies show that the prevalence rate may vary in 1% to 2,9% in a few groups. Objective: Perform a review of literature over the main aspects related to Tourette syndrome. Data synthesis: The TS is a genetic disorder, associated with neuroanatomical and neurophysiological alterations, characterized by compulsive phenomenon, whose etiology is still unknown. The clinical profile is composed, mostly, by motor tics and vocal tics, that which are divided in simple and complex. Its association with Obssessive Compulsive Disorder and Attention Deficit Hyperactivity Disorder is very commom. The diagnosis is mainly clinical and do not exist. Until now, there is no specific laboratory test that confirm this pathology. The treatment is based mainly on psychological theory. However when there is need for the use of drugs, the most widely used are the antagonists of dopamine receptors. Conclusion: The TS causes many damages as psychosocial and educational for the individual and the family. However, the diagnosis and the early treatment are able to minimize or cancel this damages. This way, knowing the general aspects that guide the TS is of utmost importance to preserve the quality of life for the patients with the disease.

    Full Text Available Abstract Background High income nations are currently exhibiting increasing ethno-cultural diversity which may present challenges for nursing practice. We performed an integrative review of literature published in North America and Europe between 1990 and 2007, to map the state of knowledge and to identify nursing assessment tools/models which are have an associated research or empirical perspective in relation to ethno-cultural dimensions of nursing care. Methods Data was retrieved from a wide variety of sources, including key electronic bibliographic databases covering research in biomedical fields, nursing and allied health, and culture, e.g. CINAHL, MEDline, PUBmed, Cochrane library, PsycINFO, Web of Science, and HAPI. We used the Critical Appraisal Skills Programme tools for quality assessment. We applied Torraco's definition and method of an integrative review that aims to create new knowledge and perspectives on a given phenomena. To add methodological rigor with respect to the search strategy and other key review components we also used the principles established by the Centre for Reviews and Dissemination. Results Thirteen thousand and thirteen articles were retrieved, from which 53 full papers were assessed for inclusion. Eight papers met the inclusion criteria, describing research on a total of eight ethno-cultural assessment tools/models. The tools/models are described and synthesized. Conclusions While many ethno-cultural assessment tools exist to guide nursing practice, few are informed by research perspectives. An increased focus on the efficiency and effectiveness of health services, patient safety, and risk management, means that provision of culturally responsive and competent health services will inevitably become paramount.

  4. A literature review of safety culture.

    2013-03-01

    Workplace safety has been historically neglected by organizations in order to enhance profitability. Over the past 30 years, safety concerns and attention to safety have increased due to a series of disastrous events occurring across many different industries (e.g., Chernobyl, Upper Big-Branch Mine, Davis-Besse etc.). Many organizations have focused on promoting a healthy safety culture as a way to understand past incidents, and to prevent future disasters. There is an extensive academic literature devoted to safety culture, and the Department of Energy has also published a significant number of documents related to safety culture. The purpose of the current endeavor was to conduct a review of the safety culture literature in order to understand definitions, methodologies, models, and successful interventions for improving safety culture. After reviewing the literature, we observed four emerging themes. First, it was apparent that although safety culture is a valuable construct, it has some inherent weaknesses. For example, there is no common definition of safety culture and no standard way for assessing the construct. Second, it is apparent that researchers know how to measure particular components of safety culture, with specific focus on individual and organizational factors. Such existing methodologies can be leveraged for future assessments. Third, based on the published literature, the relationship between safety culture and performance is tenuous at best. There are few empirical studies that examine the relationship between safety culture and safety performance metrics. Further, most of these studies do not include a description of the implementation of interventions to improve safety culture, or do not measure the effect of these interventions on safety culture or performance. Fourth, safety culture is best viewed as a dynamic, multi-faceted overall system composed of individual, engineered and organizational models. By addressing all three components of

    Patients with Systemic Lupus Erythematosus (SLE) may experience flare of disease activity. The aim of this study was to assess incidence, clinical features and predictors of flares, focusing on the relationship with serially assessed anti-double stranded DNA antibodies (anti-dsDNA) serum levels by Farr assay and pre-emptive therapeutic approaches of flares, through the analysis of a monocentric cohort of SLE patients and a literature review. Clinical and laboratory data of 120 out of 334 SLE patients, fulfilling inclusion criteria for enrolment and followed up between 1997 and 2012, were retrospectively collected. For the purposes of the study, a flare was defined as any new SLE manifestation or worsening of a pre-existing manifestation resulting in change of therapy. A review of the literature was performed searching for articles published between 1980 and 2015. Over a median (IQR) follow-up of 5.9 (3.0-8.9) years, 87 flares were recorded in 59 (49%) patients. The estimated incidence rate was 0.11 flare per patient-year, at the low-end of values reported in literature (0.19-1.76 patient-year). In our cohort, fluctuating anti-dsDNA serum levels were associated with flare development whereas precautionary change of therapy in presence of increased anti-dsDNA levels >50% was effective in preventing flares (pflares, respectively, in some studies but not in others. Differences in laboratory methods and patient selection, in terms of ethnicity, disease duration, and background therapy are likely to be crucial in determining discordant results. PMID:26921641

    2005-01-01

    In order to better understand aspects related to the nutritional assessment of patients in risk for pressure ulcers, we reviewed the national and international literature indexed on Medline and LILACS bibliographic databases, from 1987 to 2001. The aim of this research was to investigate the knowledge production on pressure ulcers and nutritional status, as well as to learn about the authors and the publication focus. We concluded that patients in risk for pressure ulcers can be early identified based on nutritional assessment, including biochemical data, anthropometric evaluation, clinical data, diet history and energetic consumption. The alterations are frequent in elderly patients, hospitalized patients, patients with a chronic disease such as a vascular cerebral accident, cancer and spinal cord injury. PMID:16613396

    2013-11-01

    Workplace-based assessments (WBAs) are trainee-led formative assessments that measure the highest level of competence of the ability to do a task. So far WBAs are the only available assessment tools to measure performance integrated into practice. Over the years, WBAs have become an integral part of dental foundation and specialty training. The numerous WBAs available can be broadly categorised into three types. The first type involves observation of clinical encounters, for example mini-clinical evaluation exercises; direct observation of procedural skills; and dental evaluation of performance and procedure-based assessments. The second type involves discussion of clinical cases, such as case-based discussions. Finally, the third type includes the mini-peer assessment tool, team assessment of behaviour, 360° assessments and multi-source feedback, and all involve receiving feedback from a combination of colleagues, staff and patients. This article describes the WBAs currently used in postgraduate dental training and explores their strengths, weaknesses, perceived value by trainees and trainers and how these tools can be used in a reliable and valid way.

    This study reviewed the use of the Strengths and Weaknesses of Attention-Deficit/Hyperactivity-symptoms and Normal-behaviors (SWAN) rating scale in diagnostic and evolutive approaches to attention deficit hyperactivity disorder (ADHD) and in correlational studies of the disorder. A review of articles published in indexed journals from electronic databases was conducted and 61 articles on the SWAN scale were analyzed. From these, 27 were selected to a) examine use of SWAN in research on attention disorders and b) verify evidence of its usefulness in the areas of genetics, neuropsychology, diagnostics, psychiatric comorbidities, neuroimaging, pharmacotherapy, and to examine its statistical reliability and validity in studies of diverse populations. This review of articles indicated a growing use of the SWAN scale for diagnostic purposes, for therapy, and in research on areas other than ADHD, especially when compared with other reliable scales. Use of the scale in ADHD diagnosis requires further statistical testing to define its psychometric properties. PMID:26313140

    2014-10-15

    Concerns over effects of halogenated persistent environmental contaminants on the developing brain have been expressed for many years, and human biomonitoring has confirmed that low-level, prenatal and/or postnatal exposure of children to these chemicals is ubiquitous. Over the last decade there have been increasing reports in the epidemiological literature of the potential association of exposure to polybromo diphenylethers (PBDEs) and perfluorinated chemicals (PFCs) with neurodevelopmental and/or neurobehavioural effects in infants and children, such as adverse birth outcomes, cognitive deficits, developmental delay and attention deficit hyperactivity disorders (ADHD). However, direct evidence from epidemiology studies has been limited and contradictory. Given the general lack of comparability across studies in terms of design, conduct, methodology and reporting, we developed a checklist-type quality assessment scheme based on the STROBE guidelines and the proposed HONEES criteria, and conducted a systematic review of the epidemiological peer-reviewed literature published since 2006 on neurodevelopmental and/or neurobehavioural effects following prenatal and postnatal exposure to PBDEs and PFCs. We rated 7 of the 18 studies that met our inclusion criteria as being of high quality, 7 of moderate quality and 4 of low quality. Frequently observed shortcomings were the lack of consideration of confounding factors; uncertainties regarding exposure characterization; inadequate sample size; the lack of a clear dose-response; and the representativeness/generalizability of the results. Collectively, the epidemiological evidence does currently not support a strong causal association between PBDEs and PFCs and adverse neurodevelopmental and neurobehavioural outcomes in infants and children. However, despite their limitations, the studies raise questions that require further investigation through hypothesis-driven studies using more harmonized study designs and methodologies

We have reviewed the literature to identify disease-specific and non-disease-specific sleep PROMs that have been validated for use in COPD patients. The review also examined the psychometric properties of identified sleep outcome measures and extracted point and variability estimates of sleep instruments used in COPD studies. Methods: The online EMBASE, MEDLINE, PsycINFO, and SCOPUS databases for all years to May 2014 were used to source articles for the review. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Criteria from the Medical Outcomes Trust Scientific Advisory Committee guidelines were used to evaluate the psychometric properties of all sleep PROMs identified. Results: One COPD-specific and six non-COPD-specific sleep outcome measures were identified and 44 papers met the review selection criteria. We only identified one instrument, the COPD and Asthma Sleep Impact Scale, which was developed specifically for use in COPD populations. Ninety percent of the identified studies used one of two non-disease-specific sleep scales, ie, the Pittsburgh Sleep Quality Index and/or the Epworth Sleep Scale, although neither has been tested for reliability or validity in people with COPD. Conclusion: The results highlight a need for existing non

    2015-09-01

    The recent interest in systematic review methods in bioethics has highlighted the need for greater transparency in all literature review processes undertaken in bioethics projects. In this article, I articulate features of a good bioethics literature review that does not aim to be systematic, but rather to capture and analyse the key ideas relevant to a research question. I call this a critical interpretive literature review. I begin by sketching and comparing three different types of literature review conducted in bioethics scholarship. Then, drawing on Dixon-Wood's concept of critical interpretive synthesis, I put forward six features of a good critical interpretive literature review in bioethics: answering a research question, capturing the key ideas relevant to the research question, analysing the literature as a whole, generating theory, not excluding papers based on rigid quality assessment criteria, and reporting the search strategy.

    One of many alternate sources of electrical energy that are being considered by the Department of Energy is a microwave-mediated Satellite Power System (SPS). Once inserted into geosynchronous orbit at an altitude of more than 40,000 kilometers, a satellite would collect then convert the sun's energy to 2450-MHz microwaves, which would be beamed to the Earth's surface, where a rectifying antenna (rectenna) would convert the microwaves to electrical current suitable for industrial and domestic use. The expanse of each rectenna (about 10 by 13 kilometers), the power density of the continuous-wave microwave beam (approx. 23 mW/cm/sup 2/ at center, with fall off to 1 mW/cm/sup 2/ or less at the periphery of the rectenna), and the possibility that 20 or more satellite systems will eventually be operating, creates two sets of interrelated problems for biological/ecological assessment. These are 1) the effects of microwave fields of higher intensity on airborne biota (including human beings in aircraft) that may traffic the area above the rectenna and 2) the effects of virtually perpetual fields of much lower intensity on all forms of life at and beyond the rectennae's zone of exclusion. In this review, the scientific literature is examined, not only for biological effects that are pertinent to assessment of SPS, but for hiatuses of knowledge that will have to be filled before SPS can be vouched for operational safety.

    2015-05-01

    Full Text Available Psychological resilience is comprised of an adaptive functioning standard before the current and accumulated risks of life. Furthermore, it has a comprehensive range of psychological resources which are essential to overcome adversities, such as personal competences, self-beliefs and interpersonal control which interact with the social networks support. The objectives are to show the concepts of psychological resilience in elderly, relative to dominant theoretical models and the main data about psychological resilience in aging, found in an international and Brazilian review from 2007 to 2013. The descriptors "resilience, psychological resilience and aging", "resiliência e envelhecimento, velhice e velho", were used in PubMed, PsychInfo, SciELO and Pepsic databases. Fifty three international and eleven national articles were selected. The international articles were classified in four categories: psychological and social coping resources, emotional regulation before stressing experiences, successful resilience and aging and correlates, and resilience measures. The Brazilian articles were grouped in three: psychological and social resources, resilience in carers and theory review. Articles on psychological resources and on emotional regulation prevailed as key factors associated with psychological resilience in aging.

  20. Packrat Parsing: A Literature Review

    Manish M. Goswami

    2016-03-01

    Full Text Available Packrat parsing is recently introduced technique based upon expression grammar. This parsing approach uses memoization and ensures a guarantee of linear parse time by avoiding redundant function calls by using memoization. This paper studies the progress made in packrat parsing till date and discusses the approaches to tackle this parsing process efficiently. In addition to this, other issues such as left recursion, error reporting also seems to be associated with this type of parsing approach and discussed here the efforts attempted by researchers to address this issue. This paper, therefore, presents a state of the art review of packrat parsing so that researchers can use this for further development of technology in an efficient manner.

  1. Empirical Models of Demand for Out-Patient Physician Services and Their Relevance to the Assessment of Patient Payment Policies: A Critical Review of the Literature

    Directory of Open Access Journals (Sweden)

    Olga Skriabikova

    2010-06-01

    Full Text Available This paper reviews the existing empirical micro-level models of demand for out-patient physician services where the size of patient payment is included either directly as an independent variable (when a flat-rate co-payment fee or indirectly as a level of deductibles and/or co-insurance defined by the insurance coverage. The paper also discusses the relevance of these models for the assessment of patient payment policies. For this purpose, a systematic literature review is carried out. In total, 46 relevant publications were identified. These publications are classified into categories based on their general approach to demand modeling, specifications of data collection, data analysis, and main empirical findings. The analysis indicates a rising research interest in the empirical micro-level models of demand for out-patient physician services that incorporate the size of patient payment. Overall, the size of patient payments, consumer socio-economic and demographic features, and quality of services provided emerge as important determinants of demand for out-patient physician services. However, there is a great variety in the modeling approaches and inconsistencies in the findings regarding the impact of price on demand for out-patient physician services. Hitherto, the empirical research fails to offer policy-makers a clear strategy on how to develop a country-specific model of demand for out-patient physician services suitable for the assessment of patient payment policies in their countries. In particular, theoretically important factors, such as provider behavior, consumer attitudes, experience and culture, and informal patient payments, are not considered. Although we recognize that it is difficult to measure these factors and to incorporate them in the demand models, it is apparent that there is a gap in research for the construction of effective patient payment schemes.

  2. Trace element emissions. Literature review

    International Nuclear Information System (INIS)

    Application of fossil fuels by various utilities results in the emission of trace elements to air, water and solid waste streams. Elements present in coal are released as particles or as vapours during coal combustion or gasification. Owing to the increased consumption of coal, especially for power generation, huge quantities of potentially hazardous trace elements are released into the atmosphere every year. It is necessary to evaluate the emissions of each trace element from coal-fired combustion or gasification systems, and their effects on the environment. Present research interests should be aimed at determining the sources, concentrations, and environmental impact of trace elements related with energy generation and relevant control technologies. Two of the emerging advanced coal gasification technologies, such as integrated gasification combined cycle (IGCC) and integrated gasification fuel cell (IGFC) are presently experiencing potential difficulties due to trace element emissions. In order to control the levels of these contaminants within regulatory limits and to ensure the efficient operation of fuel cells, it is necessary to determine the type and quantity of trace elements emitted from coal gasification-based systems as a function of system, operating conditions, and type of coal. The partitioning of the trace elements is influenced by the gasification conditions. In general, the following gasification conditions are expected to influence the distribution of trace elements between various product streams. (a) reducing and oxidizing environments (b) gas phase composition, pressure and temperature. The present report was aimed at finding and identifying gaps existing in the literature on the trace element transformations during gasification. Also included in the report is the modelling of relevant transformation mechanisms of the trace elements during gasification as a function of coal type and process conditions. 7 figs., 6 tabs., 69 refs

  3. PELLETIZATION TECHNIQUES: A LITERATURE REVIEW

    Directory of Open Access Journals (Sweden)

    Punia Supriya

    2012-03-01

    Full Text Available In present times, the pelletization technologies are gaining much attention as they represent an efficient pathway for manufacture of oral drug delivery systems. This is due to the reason that pellets offer many therapeutic, technological as well as biopharmaceutical advantages over the conventional oral dosage forms. Pelletization technique enables the formation of spherical beads or pellets with a mean diameter usually ranging from 0.5-2.0 mm which can be eventually coated for preparation of modified release dosage forms. Pelletization leads to an improvement in flowability, appearance and mixing properties thus avoiding generation of excessive dust and reducing segregation, and, generally, eliminating undesirable properties and improving the physical and chemical properties of fine powders. Pellets are produced by various techniques, such as, extrusion/ spheronization, layering, cryopelletization, freeze pelletization, spray congealing, spray drying and compression. Amongst various techniques, Extrusion/Spheronization technique is the most widely utilized technique due to its high efficiency and simple and fast processing. The aim of this paper is to review some general aspects about pellets and pelletization and some common techniques being utilized in the pharmaceutical industry.

  4. Feminizing adrenocortical tumors: Literature review

    On the biological point, estrogen overproduction with or without increase in other adrenal hormones are the main abnormalities. Radiological examination usually shows the tumor, describes its limits and its eventual metastases. Adrenal and endocrine origins are confirmed by biochemical assessments and histology, but that one is unable to distinguish between benign and malignant tumors, except if metastases are already present. Immunostaining using anti-aromatase antibodies is the only tool that distinguishes FAT from other adrenocortical tumors. Abdominal surgery is the best and the first line treatment. For large tumors (≥10 cm, an open access is preferred to coeliosurgery, but for the small ones, or when the surgeon is experienced, endoscopic surgery seems to give excellent results. Surgery can be preceded by adrenolytic agents such as ortho paraprime dichloro diphenyl dichloroethane (Mitotane, ketoconazole or by aromatase inhibitors, but till now there is not any controlled study to compare the benefit of different drugs. New anti-estrogens can be used too, but their results need to be confirmed in malignant tumors resistant to classical chemotherapy and to conventional radiotherapy. Targeted therapy can be used too, as in other adrenocortical tumors, but the results need to be confirmed.

    Full Text Available Performance evaluation of an economic entity requires approaching several criteria, such as industry and economic entity type, managerial and entrepreneurial strategy, competitive environment, human and material resources available, using a system of appropriate performance indicators for this purpose.The exigencies of communication occurred on the growing number of phenomena that marked the global economy in recent decades (internationalization and relocation of business crises and turmoil in financial markets, demand performance measurement to be made in a comprehensive way by financial and non-financial criteria. Indicators are measures of performance used by management to measure, report and improve performance of the economic entity. The relationship between indicators and management is ensured by the existence of performance measurement systems. Studies to date indicate that economic entities using balanced performance measurement systems as a key management tool registered superior performance compared to entities not using such systems. This study attempts to address the issue of performance evaluation by presenting opinions of different authors concerning the process of performance measurement and to present, after revising the literature, the evolution of the performance evaluation systems. We tried to do this literature review because sustainable development and, therefore, globalization require new standards of performance that exceeds the economic field, both for domestic companies as well as international ones. So, these standards should be integrated into corporate strategy development to ensure sustainability of activities undertaken by harmonizing the economic, social and environmental objectives. To assess the performance of economic entities it is required that performance evaluation to be done with a balanced multidimensional system, including both financial ratios and non-financial indicators in order to reduce the limits of

  16. Burnout in journalists: A systematic literature review

    Directory of Open Access Journals (Sweden)

    Jasmine B. MacDonald

    2016-06-01

    Full Text Available The present study aims to provide a concise, comprehensive, and systematic review of the quantitative literature relating to the experience of burnout in journalists of various specialties and mediums. The systematic review method adopted is that prescribed by Fink (2010, which contains three main elements: Sampling the literature, screening the literature, and extracting data. Results indicate that journalists most at risk of burnout are females who are younger, with fewer years of journalism experience, working in small circulation newspapers. Editors and reporters seem to experience higher levels of burnout than those in other roles, as do journalists in non-management positions. The thorough and structured process adopted in this review provides the ability to assert with some degree of certainty what areas within the burnout and journalism literature require further consideration. This review emphasises and problematises the large focus on male reporters in newspaper settings, settings that are becoming less significant over time. Studies have tended to focus on reporters, without providing a convincing a priori rationale. What is lacking is consideration of other role groups central to broadcast news, such as camera-operators. A range of methodological and theoretical issues and future areas of research are discussed.

Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations 56.6% (132/233, pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis 38.2% (89/233 and ZIKV studies (molecular characterisation and in vitro evaluation of the virus 18.5% (43/233. There has been little reported in the primary literature on ZIKV vectors (12/233, surveillance for ZIKV (13/233, diagnostic tests (12/233 and transmission (10/233. Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233, of which 62/233 were case studies or case series, while fewer (24/233 used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health.

    The global primary literature on Zika virus (ZIKV) (n = 233 studies and reports, up to March 1, 2016) has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations) 56.6% (132/233), pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis) 38.2% (89/233) and ZIKV studies (molecular characterisation and in vitro evaluation of the virus) 18.5% (43/233). There has been little reported in the primary literature on ZIKV vectors (12/233), surveillance for ZIKV (13/233), diagnostic tests (12/233) and transmission (10/233). Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233), of which 62/233 were case studies or case series, while fewer (24/233) used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health. PMID:27244249

    2013-01-01

    Full Text Available The purpose of this paper was to review the literature on caring among nurses. The approach utilized studies on nurse caring behaviors in a variety of patient care settings. Articles published between 1987-2012 in the CINAHL, Medline, and PubMed databases were used. Overall, fourteen different articles were deemed relevant and were included in the review. The review articles were grouped into three categories which were Acute/Surgical, Community/Institutionalized, and Postpartum/Childbirth. In conclusion, human needs assistance was a consistent aspect of caring valued by patients.  We recommend that nurses learn their patient’s likes and dislikes while also providing for topics related to patient physical needs. Also when caring for children, nurses should use entertainment and humor as part of their caring approach.

    Causal correlations between environmental contamination with PCBs and PCDD/Fs and food and feed contamination with these substances are not been found so far. Because of the high importance of the transfer of these substances into the food chain this is subject to wide research. The present literature review summarizes the actual knowledge regarding emission, exposition and transfer of PCBs and Dioxins within the food chain. A particular focus has been laid to sources of emission, distribution processes and exposure assessment for environment and consumer. International publications as well as publications and reports on a German national level and so called ''grey'' literature were evaluated. In general it can be noticed that comparison of different publications is difficult since the authors usually do not differentiate between non-dioxin-like PCBs (ndl-PCBs) and dioxin-like PCBs (dl-PCBs). Most authors mix dl-PCBs and ndl-PCBs, a breakdown of the PCBs in single congeners is rarely given. Extended Abstract Due to atmospheric translocation PCBs and PCDD/Fs are ubiquitous distributed in the environment. The emissions in Germany could be reduced drastically in the first half of the nineties due to regulatory restrictions. At the same time contaminations detected in food and feed dropped down. But since 1997 no significant further reduction of environmental concentrations of PCBs and PCDD/Fs can be observed. Present emissions of PCBs and PCDD/Fs derive from nonpoint sources mainly, e.g. remobilisation from soils and sediments by surface erosion and volatilization. Further increasing emissions of PCDD/Fs are expected due to promotion of renewable energies (combustion of wood). A short term reduction of environmental concentrations is not likely due to the persistence of the compounds. Major exposure pathway for plants is via dry and wet deposition of contaminated particles and volatiles, depending on the physical-chemical properties of the various

    Bronchoscopy is the preferred method for collecting biological samples from the lower airways of subjects in clinical research. However, ensuring participation in clinical research can be challenging when the research includes an invasive procedure. For this report we reviewed the literature to look for information on participation in research bronchoscopy studies to better design our own study, the Bergen COPD Microbiome study (MicroCOPD). We performed a systematic literature search on participation in research bronchoscopy studies in February 2014 using the search engines of PubMed and EMBASE. The literature search resulted in seven relevant papers. Motivation was an end point in six of the seven papers, but reasons for declining participation and recruitment strategies also seemed important. Human subjects participate in research bronchoscopy studies for personal benefit and altruistic reasons. Inconvenience associated with research, in addition to fear of procedures, is considered a barrier. Radio, especially news stations, generated the most inquiries for a clinical study involving bronchoscopy. There is a lack of information on participation in research bronchoscopy studies in the literature. A bronchoscopy study has been initiated at Haukeland University Hospital, Bergen, Norway, to examine the role of the microbiome in COPD, and participation will be explored as a substudy.

    Full Text Available The use of learning technologies, especially multimedia provide varied facilities for students’ learning that are not possible with other media. Pedagogical literature has proved that individuals have different learning styles. Flipped classroom is a pedagogical approach which means that activities that have traditionally taken place inside the classroom take place outside the classroom and vice versa. Flipped classroom environment ensures that students become more active participants compared with the traditional classroom. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of flipped classroom approach in education. The contribution of flipped classroom to education is discussed in relation to the change of students' and instructors' role. Subsequently, flipped classroom applications in various disciplines of education are illustrated. The recommendations made in the literature for design specifications that integrate flipped classrooms with technology are discussed. The paper concludes that a careful consideration of the warnings and recommendations made in the literature can help to produce effective flipped classroom environments and also this paper attempts to inform those who are thinking of using new technologies and approaches to deliver courses.

    2016-01-01

    Inducible urticaria is a heterogeneous group of skin disorders characterized by the appearance of wheals, pruritus and/or angioedema, sometimes accompanied by systemic symptoms caused by innocuous stimuli (cold, heat, pressure, etc.). This group of disorders compromises people's quality of life and most of the literature in this regard comes from case reports and case series since its epidemiology has been poorly studied and some cases are very rare. The aim of this review is to show an up-to-date overview of the available literature for various types of inducible urticarias, always beginning with an illustrative case and then describing their pathophysiological mechanisms, clinical manifestations, and treatment.

    Schmidt, Manuela

    2013-01-01

    Aims: Through the review of relevant literature this study illuminates the concepts of social marketing and breastfeeding. It specifically discusses the positioning of the link between social marketing and breastfeeding within different fields of study and develops a theoretical framework that tries to bridge the gap between those disciplines. Method: Various electronic databases were used and through systematic selection 11 scientific articles were identified that this literature review is based on. Results: The review indicates that the relationship between social marketing and breastfeeding is complex. There are indications that this relationship is being investigated within three distinct fields of research: psychology/education, public health and marketing. Depending on the research field the emphasis is put on either breastfeeding or social marketing as well as on the other concepts that were discovered to be of importance within this relationship. Namely, group and individual demography as well as behaviour were revealed to be important elements of the link between social marketing and breastfeeding. Conclusions: Based on the results this study concludes that a more multidimensional view on the relationship between the concepts under study is needed since the focus of previous studies is very one-sided and limited to just one element when all elements should be integrated equally.

    In previous decades, manufacturers faced a lot of challenges because of globalization and high competition in markets. These problems arise from shortening product life cycle, rapid variation in demand of products, and also rapid changes in manufcaturing technologies. Nowadays most manufacturing companies expend considerable attention for improving flexibility and responsiveness in order to overcome these kinds of problems and also meet customer's needs. By considering the trend toward the shorter product life cycle, the manufacturing environment is towards manufacturing a wide variety of parts in small batches [1]. One of the major techniques which are applied for improving manufacturing competitiveness is Cellular Manufacturing System (CMS). CMS is type of manufacturing system which tries to combine flexibility of job shop and also productivity of flow shop. In addition, Dynamic cellular manufacturing system which considers different time periods for the manufacturing system becomes an important topic and attracts a lot of attention to itself. Therefore, this paper made attempt to have a brief review on this issue and focused on all published paper on this subject. Although, this topic gains a lot of attention to itself during these years, none of previous researchers focused on reviewing the literature of that which can be helpful and useful for other researchers who intend to do the research on this topic. Therefore, this paper is the first study which has focused and reviewed the literature of dynamic cellular manufacturing system.

    Mass customization (MC) is emerging as a competitive advantage of firms with the intensified competition and economic globalization.As a key feature of MC,postponement strategy postpones activities in the supply chain until customer orders are received.This article provides a review of the literature on postponement from perspectives of research content and methodology.Taking postponement as a supply chain concept,this article specifically reclassifies the postponement applications according to the positioning of the customer order decoupling point (CODP) in the supply chain.Future directions for postponement research are also suggested in this article.

  6. Emphysematous gastritis: case report and literature review

    International Nuclear Information System (INIS)

    Emphysematous gastritis is a rare form of gastritis that results from infection of the stomach wall by gas-forming organisms. Diagnosis of this commonly fatal condition rests on radiological demonstration of gas within the stomach wall. This can be observed on plain radiographs or CT scans of the abdomen. Only by prompt diagnosis and treatment can mortality be avoided. A new case of empysematous gastritis, diagnosed on CT scan by the demonstration of both intramural and portal venous gas, is presented and the literature is reviewed.

    2013-07-01

    Full Text Available Alveolar proteinosis is a rare disease. Its etiology, pathology, and manifestations are becoming increasingly more apparent. Few cases have been reported, which highlights the importance of reporting this case and reviewing current literature. New therapeutic options are being introduced with adequate outcomes thereby making it possible to manage patients who were previously unresponsive to conventional treatment. 25% of cases resolve spontaneously, while most patients require conventional treatment with total lung lavage that often does not improve prognosis. The case reported in this article was associated to Mycobacterium tuberculosis infection and diabetes. Primary alveolar proteinosis can have a direct relationship to these concomitant conditions.

    Full Text Available Software Maintainability is one of the most important quality attributes. To increase quality of a software, to manage software more efficient and to decrease cost of the software, maintainability, maintainability estimation and maintainability evaluation models have been proposed. However, the practical use of these models in software engineering tools and practice remained little due to their limitations or threats to validity. In this paper, results of our Literature Review about maintainability models, maintainability metrics and maintainability estimation are presented. Aim of this paper is providing a baseline for further searches and serving the needs of developers and customers.

    Ganglion cyst is the most common soft tissue tumour of hand. Sixty to seventy percent of ganglion cysts are found in the dorsal aspect of the wrist. They may affect any age group; however they are more common in the twenties to forties. Its origin and pathogenesis remains enigmatic. Non-surgical treatment is unreliable with a high recurrence rates. Open surgical excision leads to unsightly scar and poor outcome. Arthroscopy excision has shown very promising result with very low recurrence rate. We reviewed the current literature available on dorsal wrist ganglion. PMID:25983472

    Fatigue has been noticeably under-researched in the maritime domain compared to other transport sectors. In a review of the literature 11 databases were searched in order to assess recent developments in the field and distil those issues of greatest concern and challenge to the seafaring community. Whilst diversity in the seafaring population has the potential to make global fatigue estimates meaningless, evidence of mis-recorded working hours shows how cultural and commercial pressures are universally shared.

    Full Text Available Obesity has currently reached epidemic proportions, both in Chile and in the world. This condition is associated to a variety of maternal complications in all stages of the vital cycle and during pregnancy. Medical treatment has not proved successful thus resulting in an increase in bariatric surgery in recent years, even when it is not first line treatment. This literature review aims to report updated results of surgical treatment for obesity before and during pregnancy with respect to fertility, gestational diabetes, pre-eclampsia and pregnancy-induced hypertension. It also looks into the possible effects of surgery on fetal development, and its relation to premature delivery, fetal macrosomy, low birth weight and neural tube defects, as well as effects on maternal and fetal outcomes, mainly in nutrition. Lastly, we suggest some recommendations that arise from this review on the role of contraception, nutrition and time between surgery and pregnancy.

    Research on the transgender population is often limited to their medical care, and in particular to their mental well-being. The social and family environment in which a social gender role transition takes place is often overlooked. Although research is limited, this article reviews the existing literature on the family aspect of a gender transition. Articles regarding three different aspects were selected for this review: first, the issue of parenthood during transition and the experiences of children with a transgender parent, second, the experiences of partners and ex-partners of transgender individuals, and third, the experiences of parents with a gender variant child. Articles were restricted to those with a focus on family members and situations during transition. For all three contexts, several mediating factors, both individual and social, were distinguished. Various challenges for future research were identified. PMID:26618401

    2012-06-01

    The Montessori method was initially applied to children, but now it has also been applied to people with dementia. The purpose of this study is to systematically review the research on the effectiveness of this method using Medical Literature Analysis and Retrieval System Online (Medline) with the keywords dementia and Montessori method. We selected lo studies, in which there were significant improvements in participation and constructive engagement, and reduction of negative affects and passive engagement. Nevertheless, systematic reviews about this non-pharmacological intervention in dementia rate this method as weak in terms of effectiveness. This apparent discrepancy can be explained because the Montessori method may have, in fact, a small influence on dimensions such as behavioral problems, or because there is no research about this method with high levels of control, such as the presence of several control groups or a double-blind study.

  17. Issues in benchmarking human reliability analysis methods: A literature review

    International Nuclear Information System (INIS)

    There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessments (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study comparing and evaluating HRA methods in assessing operator performance in simulator experiments is currently underway. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies is presented in order to aid in the design of future HRA benchmarking endeavors.

    2016-01-01

    Dance imagery is a consciously created mental representation of an experience, either real or imaginary, that may affect the dancer and her or his movement. In this study, imagery research in dance was reviewed in order to: 1. describe the themes and ideas that the current literature has attempted to illuminate and 2. discover the extent to which this literature fits the Revised Applied Model of Deliberate Imagery Use. A systematic search was performed, and 43 articles from 24 journals were found to fit the inclusion criteria. The articles were reviewed, analyzed, and categorized. The findings from the articles were then reported using the Revised Applied Model as a framework. Detailed descriptions of Who, What, When and Where, Why, How, and Imagery Ability were provided, along with comparisons to the field of sports imagery. Limitations within the field, such as the use of non-dance-specific and study-specific measurements, make comparisons and clear conclusions difficult to formulate. Future research can address these problems through the creation of dance-specific measurements, higher participant rates, and consistent methodologies between studies. PMID:27245944

    Full Text Available Introduction and objective: Several studies have associated temporomandibular disorders (TMD and fibromyalgia (FM finding a wide variation of results. The aim of this study was to review the literature about the relationship between TMD and FM. Literature review: For many years, TMD and FM were considered different clinical entities, but recently, some authors have reported that these two clinical situations have similarities. It is important to emphasize that both in FM and TMD pain is the main symptom, including pain in face, mandible, and headache. Besides, these pain syndromes are characterized by a decrease in pain threshold and in the capacity of attenuation of descending systems of pain modulation. The relationship of comorbidity between TMD and FM may indicate, therefore, the existence of some form of central sensitization, which is common to both diseases, sharing neurochemical events. In addition, it was found that the presence of TMD is a common finding in FM patients. Conclusion: It can be concluded that FM and TMD are distinct clinical entities, although they share common signs and symptoms, especially those related to pain. Furthermore, it was observed that the prevalence of TMD in FM patients is higher than the other way around. It is also important in the diagnosis of these two diseases the differentiation between trigger and tender points, thus avoiding false diagnoses of TMD in FM patients.

  1. Landslide Susceptibility Statistical Methods: A Critical and Systematic Literature Review

    2014-05-01

    Landslide susceptibility assessment, the subject of this systematic review, is aimed at understanding the spatial probability of slope failures under a set of geomorphological and environmental conditions. It is estimated that about 375 landslides that occur globally each year are fatal, with around 4600 people killed per year. Past studies have brought out the increasing cost of landslide damages which primarily can be attributed to human occupation and increased human activities in the vulnerable environments. Many scientists, to evaluate and reduce landslide risk, have made an effort to efficiently map landslide susceptibility using different statistical methods. In this paper, we do a critical and systematic landslide susceptibility literature review, in terms of the different statistical methods used. For each of a broad set of studies reviewed we note: (i) study geography region and areal extent, (ii) landslide types, (iii) inventory type and temporal period covered, (iv) mapping technique (v) thematic variables used (vi) statistical models, (vii) assessment of model skill, (viii) uncertainty assessment methods, (ix) validation methods. We then pulled out broad trends within our review of landslide susceptibility, particularly regarding the statistical methods. We found that the most common statistical methods used in the study of landslide susceptibility include logistic regression, artificial neural network, discriminant analysis and weight of evidence. Although most of the studies we reviewed assessed the model skill, very few assessed model uncertainty. In terms of geographic extent, the largest number of landslide susceptibility zonations were in Turkey, Korea, Spain, Italy and Malaysia. However, there are also many landslides and fatalities in other localities, particularly India, China, Philippines, Nepal and Indonesia, Guatemala, and Pakistan, where there are much fewer landslide susceptibility studies available in the peer-review literature.

  2. Atlantic ocean disposal sites: literature review

    International Nuclear Information System (INIS)

    Concepts Development Incorporated (CDI) has reviewed the literature and summarized the environmental data base available for two possible waste disposal sites off the northeast coast of the United States. These sites include the 106-Mile Ocean Waste Disposal Site (DWD 106) located due east of Cape Henlopen, Delaware, and the Cape Hatteras Site (CHS). DWD 106 is now used for the disposal of industrial wastes. CHS was identified through a Sandia National Laboratories (SNL) program to locate regions suitable for the marine disposal of large structures, within the exclusive economic zone of the United States (200 nautical miles or less from the coast), in deep (>4000m) water. DWD 106 has been the subject of EPA and NOAA environmental studies in conjunction with industrial waste disposal at the site, and CHS has been described by Hollister, Bruce and Chandler (1979) and considered in a study of dissolved contaminant dispersal by Kupferman and Moore (1981). The prime objective of this study was to identify and review published accounts of environmental studies pertaining to DWD 106 or CHS. A secondary objective was to identify studies conducted within the general region (taken to be the NW Atlantic) so that in cases where site-specific data are unavailable one could identify the nearest available data set of a given category. Additionally, some effort was directed toward assembling references which would aid in the characterization of waste contaminated with traces of natural radioactive material.This document presents literature search site characterization summary material; brief discussion of the result of the waste characterization review; and a listing of bibliographic references identified to date

    Lower extremity ulcers represent a significant public health problem as they frequently progress to chronicity, significantly impact daily activities and comfort, and represent a huge financial burden to the patient and the health system. The aim of this review was to discuss the best approach for venous leg ulcers (VLUs). Online searches were conducted in Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL, and reference lists and official guidelines. Keywords considered for this review were VLU, leg ulcer, varicose ulcer, compressive therapy, compression, and stocking. A complete assessment of the patient's overall health should be performed by a trained practitioner, focusing on history of diabetes mellitus, hypertension, dietetic habits, medications, and practice of physical exercises, followed by a thorough assessment of both legs. Compressive therapy is the gold standard treatment for VLUs, and the ankle-brachial index should be measured in all patients before compression application. PMID:27210451

    Process Mining focuses on extracting knowledge from data generated and stored in corporate information systems in order to analyze executed processes. In the healthcare domain, process mining has been used in different case studies, with promising results. Accordingly, we have conducted a literature review of the usage of process mining in healthcare. The scope of this review covers 74 papers with associated case studies, all of which were analyzed according to eleven main aspects, including: process and data types; frequently posed questions; process mining techniques, perspectives and tools; methodologies; implementation and analysis strategies; geographical analysis; and medical fields. The most commonly used categories and emerging topics have been identified, as well as future trends, such as enhancing Hospital Information Systems to become process-aware. This review can: (i) provide a useful overview of the current work being undertaken in this field; (ii) help researchers to choose process mining algorithms, techniques, tools, methodologies and approaches for their own applications; and (iii) highlight the use of process mining to improve healthcare processes.

    2016-06-01

    Venous thromboembolism (VTE) is a major health concern because it increases morbidity and mortality after a surgical procedure. A number of well-defined, evidence-based guidelines are available delineating suitable use of prophylaxis to prevent deep vein thrombosis and pulmonary embolism. Despite the available literature, there are clear gaps between recommendations and clinical practice, affecting the incidence of VTE. Plastic surgeons underuse the substantiated literature and risk stratification tools that are available to decrease the incidence of VTE in the office-based surgical setting because of fear of bleeding or hematoma complications postoperatively. Venous thromboembolism creates an economic burden on both the patient and the healthcare system. The intent of this literature review is to determine existing VTE risk using assessment models available to aid in the implementation of protocols for VTE prevention, specifically for high-risk cosmetic surgical patients in office-based settings.

    There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessment (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study is currently underway that compares HRA methods with each other and against operator performance in simulator studies. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies are presented in order to aid in the design of future HRA benchmarking endeavors.

    The free fibula flap is the preferred reconstructive method for oncologic defects of the mandible. Arterial inflow of the extremity is routinely evaluated with several modalities; however, venous screening is rarely performed. Patients with cancer are at elevated risk of occult deep venous thrombosis (DVT). An asymptomatic thrombus encountered during free fibula reconstruction is a serious concern. Although such cases have been reported, we suspect the incidence of DVT during fibula free flap harvest is underappreciated. This monograph uses a case example to review risk factors for occult DVT, present a strategy for preoperative assessment, and provide a reconstructive algorithm to for mandibular reconstruction in such instances.

    CCS research has been focused on CO2 storage in geologic formations, with many potential risks. An alternative to conventional geologic storage is carbon mineralization, where CO2 is reacted with metal cations to form carbonate minerals. Mineralization methods can be broadly divided into two categories: in situ and ex situ. In situ mineralization, or mineral trapping, is a component of underground geologic sequestration, in which a portion of the injected CO2 reacts with alkaline rock present in the target formation to form solid carbonate species. In ex situ mineralization, the carbonation reaction occurs above ground, within a separate reactor or industrial process. This literature review is meant to provide an update on the current status of research on CO2 mineralization. 2

    Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS)-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence) from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide.

    Current thought and research positions which may allow for an improved capability to understand the impact of introducing automation to an existing system are established. The orientation was toward the type of studies which may provide some general insight into automation; specifically, the impact of automation in human performance and the resulting system performance. While an extensive number of articles were reviewed, only those that addressed the issue of automation and human performance were selected to be discussed. The literature is organized along two dimensions: time, Pre-1970, Post-1970; and type of approach, Engineering or Behavioral Science. The conclusions reached are not definitive, but do provide the initial stepping stones in an attempt to begin to bridge the concept of automation in a systematic progression.

    Microgrids are an increasingly common component of the evolving electricity grids with the potential to improve local reliability, reduce costs, and increase penetration rates for distributed renewable generation. The additional complexity of microgrids often leads to increased investment costs, creating a barrier for widespread adoption. These costs may result directly from specific needs for islanding detection, protection systems and power quality assurance that would otherwise be avoided in simpler system configurations. However, microgrids also facilitate additional value streams that may make up for their increased costs and improve the economic viability of microgrid deployment. This paper analyses the literature currently available on research relevant to value streams occurring in microgrids that may contribute to offset the increased investment costs. A review on research related to specific microgrid requirements is also presented.

    Love, Katie L

    2016-01-01

    This study presents a systematic literature review exploring the uses and potential benefits of Black Feminism in nursing research. Black Feminism may benefit knowledge development for nursing in a variety of ways, such as illuminating the multifaceted factors of Black women's identities in helping scholars move away from generalization of experiences, to improve understanding of health disparities, and making such changes by broadening the social consciousness of the nurse researchers, who are predominantly White. Discrimination in health disparities may be deconstructed if the focus is placed on asking different research questions and offering different interventions with the social structures that contributes to such actions. When Black Feminism guides the research method (including research questions and analysis), the accuracy of representing the experiences of Black women is increased. In this research, Black Feminism highlights experience, coping mechanisms, spiritual values, a tradition of strength, and a holistic view of identity. PMID:26930767

    Ebola virus disease (EVD) is a life-threatening viral disease with a fatality rate ranging from around 30%to 90%. The first EVD outbreak was reported in the 1970s in Zaire (now the Democratic Republic of the Congo). Until 2013, most outbreaks occurred in the Central Africa region, including Zaire, Sudan and Uganda. However, between March and October 2014, over 10 000 cases of EVD have been recorded in West Africa, such as in Guinea, Liberia, Sierra Leone, and Nigeria, and a few hospital or secondary infections of EVD have occurred in Spain and the United States of America. EVD is presently one of the world's most feared diseases. In this literature review, we describe the epidemiology, clinical features, diagnosis, and treatment of EVD.

    Horton, Khim; Tschudin, Verena; Forget, Armorel

    2007-11-01

    This article is part of a wider study entitled Value of Nursing, and contains the literature search from electronic databases. Key words for the search included 'values of nursing', 'values in nursing', 'organisational values' and 'professional identity'. Thirty-two primary reports published in English between 2000 and 2006 were identified. The findings highlight the importance of understanding values and their relevance in nursing and how values are constructed. The value of nursing is seen to be influenced by cultural change, globalization, and advancement in technology and medicine. These factors are crucial in providing a more structured and measured view of what nursing is, which will result in greater job satisfaction among nurses, better nurse retention and enhanced patient care within a supportive and harmonious organization. The findings of this review have implications for policy makers in recruitment and retention in determining the global value of nursing. PMID:17901183

    Sexual function is a profound facet of the human personality. Burns due their sudden and devastating nature can have longstanding effects on intimate function by virtue of physical sequelae as well as alterations in body image and perceived desirability. A considerable number of patients encounter problems with intimate function in burns rehabilitation; nevertheless, the topic appears to be poorly addressed in specialist centers worldwide. Review of the literature suggests that a number of parameters can affect the quality of sexual life following burn injuries including age at the time of injury, location, and severity of the burn as well as coping mechanisms employed by the individual survivor. Addressing issues of intimacy relies on awareness, education, and a holistic approach on behalf of the multidisciplinary team members and, to this effect, recommendations are made on managing sexual function concerns in burns rehabilitation.

  2. Energy storage: a review of recent literature

    International Nuclear Information System (INIS)

    Recent literature on the technological and economic status of reversible energy storage has been reviewed. A broad range of research and development activities have been pursued between 1975 and the present. Most of this work has concentrated on improving technical and economic performance of previously known storage technologies. Hydraulic pumped storage with both reservoirs above ground and compressed air storage (1 plant) are the only methods that have been adopted by electric utilities. The need for electrical energy storage in Canada has not been acute because of the large proportion of hydraulic generation which incorporates some storge and, in most cases, can readily be used for load-following. Residential heat storage in ceramic room heaters has been used in Europe for several years. For Canadian climatic and market conditions larger, central heating units would be required. Residential heat storage depends upon utilities offering time-of-use rates and none in Canada do so at present. Most seasonal storage concepts depend upon storage of low-grade heat for district heating. The cost of energy storage is highly dependent upon annual energy throughput and hence favours smaller capacity systems operating on frequent charge/discharge cycles over long-term storage. Capital costs of energy storage methods from the literature, expressed in constant dollars, are compared graphically and tentative investment costs are presented for several storage methods

    The authors reviewed the literature, published from 1970 through December 2009, on biomechanical research in dance. To identify articles, the authors used search engines, including PubMed and Web of Science, five previous review articles, the Dance Medicine and Science Bibliography, and reference lists of theses, dissertations, and articles being reviewed. Any dance research articles (English language) involving the use of electromyography, forceplates, motion analysis using photography, cinematography or videography, and/or physics analysis were included. A total of 89 papers, theses/dissertations, and abstracts were identified and reviewed, grouped by the movement concept or specialized movements being studied: alignment (n = 8), plié (8), relevé (8), passé (3), degagé (3), développé (7), rond de jambe (3), grand battement (4), arm movements (1), forward stepping (3), turns (6), elevation work (28), falls (1), and dance-specific motor strategies (6). Several recurring themes emerged from these studies: that elite dancers demonstrate different and superior motor strategies than novices or nondancers; that dancers perform differently when using a barre as opposed to without a barre, both in terms of muscle activation patterns and weight shift strategies; that while skilled dancers tend to be more consistent across multiple trials of a task, considerable variability is seen among participants, even when matched for background, years of training, body type, and other variables; and that dance teachers recommend methods of achieving movement skills that are inconsistent with optimal biomechanical function, as well as inconsistent with strategies employed by elite dancers. Measurement tools and the efficacy of study methodologies are also discussed. PMID:21442132

    Over 200 otoplasty techniques have been described in the current literature. However, relatively few articles focus on the associated complication rates. The goal of this review is to examine the incidence of complication rates associated with otoplasty procedures. An electronic search of the Pubmed database yielded 205 articles with significant overlap in search results. Twenty articles published between 2000 and 2007 adhered to our inclusion criteria. Early complications included in this review were haematoma, bleeding, infection, skin necrosis and wound dehiscence; late complications included suture extrusion, scarring, hypersensitivity, asymmetry and inaesthetic results. The cumulative incidence of early complications was low and varied from 0% to 8.4%, with the exception of two outliers. Although cumulative late complication incidences varied greatly from 0% to 47.3%, complication rates on the higher end of the spectrum were not accompanied with revision rates of the same magnitude. Comparison of the different articles was made difficult by the lack of a uniform calculation method for complication incidence, variable follow-up length and data collection, inconsistent use of operation technique and publication bias. Recommendations for future studies include: consistent use of operative technique or at least differentiate between the used surgical techniques when presenting complication rates, inclusion of only patients with bilateral primary procedures, considering each operated ear as an independent variable when calculating complication incidence and a minimum follow-up period of 2 years, with both objective and subjective data collection.

    Full Text Available The purpose of this review was to inform all medical health care professionals about cuboid syndrome, which has been described as difficult to recognize and is commonly misdiagnosed, by explaining the etiology of this syndrome, its clinical diagnosis in relation to differential diagnoses, commonly administered treatment techniques, and patient outcomes. A comprehensive review of the relevant literature was conducted with MEDLINE, EBSCO, and PubMed (1960 - Present using the key words cuboid, cuboid syndrome, foot anatomy, tarsal bones, manual therapy, and manipulation. Medical professionals must be aware that any lateral foot and ankle pain may be the result of cuboid syndrome. Once properly diagnosed, cuboid syndrome responds exceptionally well to conservative treatment involving specific cuboid manipulation techniques. Other methods of conservative treatment including therapeutic modalities, therapeutic exercises, padding, and low dye taping techniques are used as adjuncts in the treatment of this syndrome. Immediately after the manipulation is performed, the patient may note a decrease or a complete cessation of their symptoms. Occasionally, if the patient has had symptoms for a longer duration, several manipulations may be warranted throughout the course of time. Due to the fact radiographic imaging is of little value, the diagnosis is largely based on the patient's history and a collection of signs and symptoms associated with the condition. Additionally, an understanding of the etiology behind this syndrome is essential, aiding the clinician in the diagnosis and treatment of this syndrome. After the correct diagnosis is made and a proper treatment regimen is utilized, the prognosis is excellent

    Carla Holandino

    2011-09-01

    Full Text Available The World Health Organization states that deaths from cancer are increasing reaching an estimated 12 million deaths by 2030 [1]. In Brazil will be about 480,000 new cases by the end of 2011 [2]. For the treatment of cancer conventional therapies are used, such as chemotherapy[3] and radiotherapy [4] which can cause many adverse reactions. Complementary therapies such as homeopathy can be combined to traditional cancer treatment with the aim of minimizing these adverse reactions, relieving the symptoms of the disease itself and its treatment. Other complementary therapies which can aid in cancer treatment are electrotherapy, acupuncture and electroacupuncture, nutritional supplements, probiotics, phytotherapy, among others[5]. The literature shows the homeopathic medicines can be prescribed using the patient’s physical constitution as one strategy to help cancer patients [6-11]. This work aims to compile the literature review done with in vitro and in vivo models describing the mechanisms of action of homeopathic medicines used to treat different kinds of cancer. The research findings showed that homeopathy can help the patient to come to terms with the disease, after cancer diagnosis which often brings with itself denial, fear and a host of psychological disorders that cause an unbalance in the body. In addition, some works done with in vitro and in vivo models have shown that homeopathic medicines can modulate the immune system, activating macrophages and inducing the release of cytokines. These and other effects may help the body to overcome the cancer. The use of homeopathic therapy as complementary to conventional cancer treatment has promising results and should be further investigated.

Past literature has focused on comparing the components of these products on patient’s clinical improvement. The wide array of products on the market presents challenges to both clinicians and patients when trying to choose between available tear replacement therapies. Different formulations affect patients based on etiology and severity of disease. In order to provide an unbiased comparison between available tear replacement therapies, we conducted a literature review of existing studies and National Institutes of Health clinical trials on commercially available, brand name artificial tears. Outcomes evaluated in each study, as well as the percent of patients showing clinical and symptomatic improvement, were analyzed. Fifty-one studies evaluating different brands of artificial tears, and their efficacy were identified. Out of the 51 studies, 18 were comparison studies testing brand name artificial tears directly against each other. Nearly all formulations of artificial tears provided significant benefit to patients with dysfunctional tear syndrome, but some proved superior to others. From the study data, a recommended treatment flowchart was derived.

    2015-01-01

    Full Text Available Despite an increasing literature related to elder abuse, sexual abuse of older persons in general and of vulnerable adults living in nursing homes in particular is still sparsely described. The purpose of this study was to assess the state of knowledge on the subject of sexual abuse against older nursing home residents through a literature review. Systematic searches in reference databases including Cinahl, Medline, OVID Nursing Database, ISI Web of Science, PsycINFO, Cochrane Library, and SveMed + were conducted. Through several phases of selection of the articles, using strict inclusion and exclusion criteria, six articles were chosen for a deeper examination. Findings from the review show that sexual abuse occurs in nursing homes and that both older women and men are victims of sexual abuse. Perpetrators appear mainly to be staff and other residents and mainly to be men, but also women abuse both older men and older women. Findings from the literature review show that there is a need for knowledge and further research on the topic of sexual abuse against older residents in nursing homes. Furthermore, there is a need for good policies and reporting systems, as an important step in seriously addressing sexual abuse against older persons.

    Full Text Available The term corporate reputation has been mentioned in academic papers for some decades however since the 90's the debate about it has been intensified by authors of different areas of study. Therefore, there is a growing pressure around the definition of a construct and the way to measure an organization's corporate reputation. The purpose of this article is to present a literature review on corporate reputation in three different perspectives. At first, we intended to go through the literature, pointing out the different definitions presented on this theme. The second aspect refers to the identification of terms related to corporate reputation, such as corporate brand, corporate identity and corporate communication. Finally, broadening the possibilities of future empiric works, a review of the different proposals of measuring the corporate reputation of organizations is made.O tema reputação corporativa tem sido objeto de estudos acadêmicos há algumas décadas, porém, somente a partir da década de 90 intensificou-se esse interesse, manifestado por autores de diferentes áreas de estudo.

    2016-01-01

    Background: Physician dual practice is a common phenomenon in almost all countries throughout the world, which could potential impacts on access, equity and quality of services. This paper aims to review studies in physician dual practice and categorize them in order to their main objectives and purposes. Methods: Comprehensive literature searches were undertaken in order to obtain main papers and documents in the field of physician dual practice. Systematic searches in Medline and Embase from 1960 to 2013, and general searches in some popular search engines were carried out in this way. After that, descriptive mapping review methods were utilized to categorize eligible studies in this area. Results: The searches obtained 404 titles, of which 81 full texts were assessed. Finally, 24 studies were eligible for inclusion in our review. These studies were categorized into four groups - “motivation and forces behind dual practice”, “consequences of dual practice”, “dual practice Policies and their impacts”, and “other studies” - based on their main objectives. Our findings showed a dearth of scientifically reliable literature in some areas of dual practice, like the prevalence of the phenomenon, the real consequences of it, and the impacts of the implemented policy measures. Conclusion: Rigorous empirical and evaluative studies should be designed to detect the real consequences of DP and assess the effects of interventions and regulations, which governments have implemented in this field.

  17. Sexuality following trauma injury: A literature review

    Directory of Open Access Journals (Sweden)

    Kylie Marie Connell

    2014-04-01

    Full Text Available Restoration of the quality of life (QoL of trauma injury survivors is the aim of trauma rehabilitation. It is generally acknowledged that sexuality is an important component of QoL; however, rehabilitation services frequently fall short of including sexuality as a matter of routine. The literature was reviewed to examine the experiences of trauma survivors from three groups: spinal cord injury (SCI, traumatic brain injury (TBI and burns. The focus was on the impact of trauma on the QoL to identify future research directions and to advocate for the inclusion of sexuality as an integral part of rehabilitation. Databases searched were Proquest, Ovid, Cinahl, Medline, PsycInfo and Cochrane Central Register of controlled trials. A total of 36 eligible studies were included: SCI (n = 25, TBI (n = 6, burns (n = 5. Four themes were identified across the three trauma groups that were labeled as physiological impact of trauma on sexuality, cognitive-genital dissociation (CGD, sexual disenfranchisement (SD and sexual rediscovery (SR. Trauma injury has a significant impact on sexuality, which is not routinely addressed within rehabilitation services. Further sexuality research is required among all trauma groups to improve rehabilitation services and in turn QoL outcomes for all trauma survivors.

  18. Acute appendicitis in pregnancy: literature review

    Directory of Open Access Journals (Sweden)

    Antônio Henriques de Franca Neto

    2015-04-01

    Full Text Available Introduction: suspected appendicitis is the most common indication for surgery in non-obstetric conditions during pregnancy and occurs in about one in 500 to one in 635 pregnancies per year. This occurs more often in the second trimester of pregnancy. Acute appendicitis is the most common general surgical problem encountered during pregnancy. Methods: a literature review on research of scientific articles, under the terms “acute appendicitis” and “pregnancy”, in PubMed, Lilacs/SciELO, Scopus, Cochrane Library and Uptodate databases. Results: the clinical manifestations of appendicitis are similar to non-pregnant women, however, without a classic presentation, which often occurs, diagnosis is difficult and must be supported by imaging. Discussion: clinical diagnosis should be strongly suspected in pregnant women with classic findings such as abdominal pain that migrates to the right lower quadrant. The main purpose of imaging is to reduce delays in surgical intervention due to diagnostic uncertainty. A secondary objective is to reduce, but not eliminate, the negative appendectomy rate. Differential diagnosis of suspected acute appendicitis usually includes pathologies considered in non-pregnant people. Conclusion: the imaging study of choice is ultrasound, MRI may be used when the former is not conclusive and, as a last resort, a CT scan can be performed. The treatment remains appendectomy by laparotomy, since the feasibility of video- assisted surgery in these cases remains controversial.

  19. Idaho radionuclide exposure study: Literature review

    International Nuclear Information System (INIS)

    Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily 210Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report

  20. Cesium and Strontium Separation Technologies Literature Review

    2004-03-01

    Integral to the Advanced Fuel Cycle Initiative (AFCI) Program’s proposed closed nuclear fuel cycle, the fission products cesium and strontium in the dissolved spent nuclear fuel stream are to be separated and managed separately. A comprehensive literature survey is presented to identify cesium and strontium separation technologies that have the highest potential and to focus research and development efforts on these technologies. Removal of these high-heat-emitting fission products reduces the radiation fields in subsequent fuel cycle reprocessing streams and provides a significant short-term (100 yr) heat source reduction in the repository. This, along with separation of actinides, may provide a substantial future improvement in the amount of fuel that could be stored in a geologic repository. The survey and review of the candidate cesium and strontium separation technologies are presented herein. Because the AFCI program intends to manage cesium and strontium together, technologies that simultaneously separate both elements are of the greatest interest, relative to technologies that separate only one of the two elements.

    Full Text Available -The main objective of present study is to present review of literature related to capital budgeting decisions and to study the trends in using the capital budgeting techniques in depth. The study would facilitate the reader to know the past, current and future trend of capital budgeting techniques by the corporate houses. This study would provide guidelines to decision makers to make investing and financing decisions so that their profit get maximise at minimize risks.The secondary purpose of this study is to understand the rationale behind capital budgeting decisions. Whether such kinds of decisions affect the efficiency of the corporate houses. Efficiency either in terms of increase in revenue or decrease in costs of the operations. The benefits from large investments are received in some future period and the future is uncertain. For instance, a decision to acquire an asset that is going to last for 15 years requires a15-year forecast. A failure to forecast correctly will lead to serious errors which can be corrected only at a considerable expense. Future revenue involves estimating the size of the market for a product and the expected share of the firm in that. These estimates depend on a variety of factors, including price, advertising and promotions, and sales effort and so on. To what extend these estimates effect the quality of capital budgeting decisions is the more sophisticated way to explain the main objective of this study

    2010-04-01

    Sarcoidosis involving the gastrointestinal tract is extremely rare. Clinically recognizable gastrointestinal system involvement occurs in 0.1% to 0.9% of patients with sarcoidosis. We encountered a 22-year-old African American female admitted to Johns Hopkins Hospital (Baltimore, Maryland) for a 2-week history of fever, chills, eye pain, and abdominal pain. Her abdominal CT scan showed multiple subcentimeter retroperitoneal lymph nodes. An upper endoscopy was performed and discovered an antral nodule that measured about 7 mm and antral gastritis in which biopsies showed active chronic necrotizing granulomatous gastritis. Biopsies of the antral polyp showed focal intestinal metaplasia and active chronic necrotizing granulomatous pattern. Stains for Helicobacter pylori, acid fast, and fungi were negative. A small-bowel series showed no abnormality. Ophthalmologic evaluation revealed panuveitis with bilateral optic disc edema. The patient was later prescribed 60 mg of prednisone by mouth once a day and subsequently her abdominal pain and fever resolved during follow-up 2 months later. This literature review demonstrates the importance in the diagnosis, pathophysiology, clinical manifestations, types of gastric sarcoidosis, major endoscopic findings, and management of gastric sarcoidosis.

  4. Microbial-influenced cement degradation: Literature review

    International Nuclear Information System (INIS)

    The Nuclear Regulatory Commission stipulates that disposed low-level radioactive waste (LLW) be stabilized. Because of apparent ease of use and normal structural integrity, cement has been widely used as a binder to solidify LLW. However, the resulting waste forms are sometimes susceptible to failure due to the actions of waste constituents, stress, and environment. This report reviews literature which addresses the effect of microbiologically influenced chemical attack on cement-solidified LLW. Groups of microorganisms are identified, which are capable of metabolically converting organic and inorganic substrates into organic and mineral acids. Such acids aggressively react with concrete and can ultimately lead to structural failure. Mechanisms inherent in microbial-influenced degradation of cement-based material are the focus of this report. This report provides sufficient evidence of the potential for microbial-influenced deterioration of cement-solidified LLW to justify the enumeration of the conditions necessary to support the microbiological growth and population expansion, as well as the development of appropriate tests necessary to determine the resistance of cement-solidified LLW to microbiological-induced degradation that could impact the stability of the waste form

  5. Neurobrucellosis: three case reports and literature review

    2013-01-01

    Full Text Available Background Brucellosis is a multisystem disease which may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon complication of this infection. This article aims to present clinical manifestations and to discuss the clinical features and management of 3 neurobrucellosis cases. Methods The diagnosis, treatment, laboratory results and accessory examination findings of 3 patients with neurobrucellosis between August 2010 and March 2012 were retrospectively analyzed, and relevant literature was reviewed. Results All the 3 cases had definite history of exposure to epidemic areas or infectious diseases, and history of being infected with Brucella by drinking raw milk. During the screening because of fever for reasons unknown, they were proved to be infected with Brucella by etiological or serological tests. Initial clinical manifestations consisted of fever and headache, with meningitis symptoms and signs, spondylitis, uroschesis and constipation (which might be caused by lumbosacral nerve root lesion, or neurological manifestations in auditory nerve and abducent nerve, such as hearing loss and diplopia. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Conclusion Neurobrucellosis presents with various clinical signs and symptoms, and is often accompanied by systemic infection. Brucellosis should be kept in mind during the screening of fever for reasons unknown, and be differentiated from Mycobacterium tuberculosis infection. The combined treatment by antibotics of different pharmacological mechanisms with full dose and long range is effective, and the prognosis is favorable.

    Full Text Available Abstract Background Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. Methods A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Results Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13 generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30

    Full Text Available Pachydermodactyly is a rare, benign form of digital fibromatosis, characterized by asymptomatic and progressive, periarticular and usually symmetrical soft tissue finger swelling, specifically on the lateral aspects of the proximal interphalangeal joints mainly of the second, third, and fourth fingers; it mostly affects young adolescents and is probably due to repeated mechanical injury of the skin (such as repeated clasping or rubbing of crossed fingers, sometimes as a result of obsessive-compulsive disorder, which must be distinguished from obsessive “chewing pads”. This paper presents a male patient aged 19, who presented with first symptoms at the age of 12, and was diagnosed with periarticular hypertrophy: localized soft tissue thickening around the proximal interphalangeal joints of all fingers except the thumbs; slight hypertrophy of the skin; absence of subjective complaints; normal joint function. Dermatological status on admission revealed: symmetrical soft tissue swelling of all fingers of both hands except the thumbs at the level of the proximal interphalangeal joints; normal appearance of the distal parts of all fingers; thickening at the level of the proximal interphalangeal joints, bilateral, almost symmetrical hypertrophy (ulnar and radial of phalanges of the affected fingers except both index fingers, affecting only the ulnar side. The skin lesions were pain-free on palpation, with homogeneous texture and elastic consistency, freely movable over underlying structures. The affected joints showed no functional deficit. The test results, sonography, radiography and histopathology confirmed our clinical diagnosis-pachydermodactyly. The review of the currently available literature, published between 1973 and 2014, including 99 papers and 160 patients, provided important insight into the characteristics and variations of the disease.

    Full Text Available Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p < 0.0001. The average age of infected children was 8.4 and 58.5% were male. In 46.3% of cases, a risk factor was not identified, while 24.4% had AIDS. The most frequent clinical manifestations were headache (78.1%, fever (68.8%, nausea and vomiting (65.6%, confusion (50% and meningeal signs (37.5%. Meningitis was the most frequent clinical presentation (87.8%. Amphotericin B was given to 93.5% of patients as an initial treatment. Positive microbiological identification was accomplished by India ink (94.7%, latex in cerebrospinal fluid (100% and culture (89.5%. Out of 34 isolates studied, Cryptococcus neoformans var. grubii (VNI 85.3%, VNII 8.8% was isolated in 94.1% of cases and Cryptococcus gattii (VGII was isolated in 5.9% of cases. These data are complemented by a literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide.

  11. Microalgae harvesting and processing: a literature review

    Shelef, G.; Sukenik, A.; Green, M.

    1984-08-01

    The objective of this report is to present a discussion of the literature review performed on methods of harvesting microalgae. There is no single best method of harvesting microalgae. The choice of preferable harvesting technology depends on algae species, growth medium, algae production, end product, and production cost benefit. Algae size is an important factor since low-cost filtration procedures are presently applicable only for harvesting fairly large microalgae. Small microalgae should be flocculated into larger bodies that can be harvested by one of the methods mentioned above. However, the cells' mobility affects the flocculation process, and addition of nonresidual oxidants to stop the mobility should be considered to aid flocculation. The decision between sedimentation or flotation methods depends on the density difference between the algae cell and the growth medium. For oil-laden algae with low cell density, flotation technologies should be considered. Moreover, oxygen release from algae cells and oxygen supersaturation conditions in growth medium support the use of flotation methods. If high-quality algae are to be produced for human consumption, continuous harvesting by solid ejecting or nozzle-type disc centrifuges is recommended. These centrifuges can easily be cleaned and sterilized. They are suitable for all types of microalgae, but their high operating costs should be compared with the benefits from their use. Another basic criterion for selecting the suitable harvesting procedure is the final algae paste concentration required for the next process. Solids requirements up to 30% can be attained by established dewatering processes. For more concentrated solids, drying methods are required. The various systems for algae drying differ both in the extent of capital investment and the energy requirements. Selection of the drying method depends on the scale of operation and the use for which the dried product is intended.

    Full Text Available Marilita M Moschos,1 Nikolaos S Gouliopoulos,1 Christos Kalogeropoulos2 1Laboratory of Electrophysiology, First Department of Ophthalmology, University of Athens, Athens, Greece; 2Department of Ophthalmology, University of Ioannina, Ioannina, Greece Purpose: Uveitis is the inflammation of the uveal tract, which usually also affects the retina and vitreous humor. The electrophysiological examination is an objective ocular examination that includes the electroretinogram, visual evoked potentials, the electrooculogram, the multifocal electroretinogram, and multifocal visual evoked potentials. Our aim is to review the literature of the use of the electrophysiological examination in cases of uveitis. Methods: We performed a systematic search of the literature of published papers until October 2012 using the PubMed search engine. The key terms that were used were “uveitis,” “electrophysiological examination”, “electroretinogram”, “visual evoked potentials”, “electro-oculogram”, “multifocal electroretinogram”, and “multifocal visual evoked potentials” in multiple combinations. To the best of our knowledge, this is the first review concerning the assessment of electrophysiology in uveitis. Results: Our search of the literature demonstrated that the electrophysiological examination, mainly by means of electroretinogram, multifocal electroretinogram, and visual evoked potentials, is performed in several cases of uveitis for many purposes, including diagnosis and monitoring of disease progression and treatment efficacy. The electrophysiological examination is more useful in patients with multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, birdshot chorioretinopathy, Vogt–Koyanagi–Harada disease, Adamantiades–Behçet disease, ocular syphilis, and Fuchs heterochromic cyclitis. Conclusion: This review summarizes the use of the electrophysiological examination in uveitic patients

    Otto, Laureen A; Gurney, Cindy

    2006-01-01

    In the 2000-2003 New York State Nurses Association Strategic Plan, the Board of Directors called for an assessment of the progress made toward achieving an ethnically diverse nursing workforce as reflected in the literature. In this paper the authors have responded to that request and offer a snapshot of progress as well as standstills in the journey toward diversity. Although the literature has tended to focus on cultural competency of the healthcare worker, and includes numerous calls for action to diversify the nurse workforce, very little scholarly work has been conducted that rigorously evaluates such diversification activities. The purpose of this literature review is to explore existing scholarly work in ethnic diversity at three levels: in the general workforce, the healthcare workforce, and the nursing workforce. The authors explored the literature as it addresses two aspects: academic and career factors influencing diversity; and recruitment, retention, and other strategies employed to diversify the workforce. By exploring the existing research, gaps can be identified in order to either direct further research, or target funding to recruitment strategies to effectively enhance a more ethnically diverse nurse workforce.

  15. Effects of earthquakes on underground facilities. Literature review and discussion

    International Nuclear Information System (INIS)

    A review of literature concerning effects of ground motion on underground facilities has been completed, and an annotated bibliography has been prepared. This information provides useful background for the science and engineering of underground nuclear waste management facility development. While some conflicts are evident in the literature reviewed, the following tentative conclusions may be drawn from the available information: (1) damage is expectable if fault displacement occurs through a site, but damage from shaking alone is generally confined to facilities located within the epicentral region and may be less than to surface facilities at the same site. (2) Seismic data are mixed, but favors reduction of amplitude with depth; observations appear quite dependent upon station characteristics. (3) The frequency content of earthquake mitions is important to the stability of underground openings and the applicability of attenuation relationships developed in areas where geologic and tectonic characteristics favor high attenuation rates to mid-continental sites is questionable. (4) Model studies indicate problems for shafts and the potential for problems with waste-handling equipment in shafts. The results of the review indicate the need to assure that site-specific response spectra and attenuation relationships are developed for proposed sites, and that detailed assessments of seismic aspects of shaft designs, hoists and in-shaft waste-handling equipment are required

    Full Text Available Rural heritage tourism destination management is an essential knowledge area that should be investigated to achieve sustainable destination, especially for an emerging destination. The goal of this process is to ensure that these elements are thoroughly inspected and rigidly organized due to the main concepts, theories, methods and approaches mentioning different perspectives to tackle these certain elements. In order to cope with the complexity of the relation between the destination elements and its characteristics and sequence of the maturity of the selected destination, all that needs in-depth knowledge to assist the researchers in developing and improving different types of approaches and tools, and in structuring and assessing the destination. We develop a neat backbone literature review concerning the all aspects of the sustainable rural heritage tourism destination. We review the existing methods, approaches and theories applied on the relative field, and further study the relevant challenges that have been the target of investigation in the academic literature. The paper is intended to be the newest and the most important existing study on the topic of rural heritage emerging tourism destination. The results are particularly relevant to practitioners seeking a better grasp on managing tourism destination as well as achieving sustainability in tourism destinations. As a major finding of the review, the results strongly suggest the need for more practitioner-oriented and industry-driven empirical studies in the area of flexible managerial framework to cope with special and dynamic characteristics of different tourism destinations.

    Regional planning has been increasingly regarded as an important way to manage regional resources and coordinate regional development. Practically, regional planning is in face of severe challenges in its imple- mentation stage. Plans are always revised or even collapsed during the actual implementation process. Presently the work of planning is attracting more and more concerns, as well as criticisms. One of the reasons that plan- ning fails in implementation lies in the reason that planning is, by nature, a long-term procedure, which involves a lot of uncertainties. Plans should be evaluated according to the real situation to generate feedbacks and carry out necessary adjustments, so that plans could achieve their best efficiency. Therefore, evaluation is considered as an indispensable process that can ensure the plans will be implemented successfully. Evaluation is not only necessary for building up and stabilizing the social status of regional planning, bu also helpful for understanding the defects and the failure of plans so that evaluation would practically promote the progress of planning in the future. However, research and application of evaluation falls behind regional planning presently. This paper, by reviewing a large amount of past literatures, advocates that the evaluation of regional planning is experiencing the shift from "planning outcome as blueprint" to "the process of planning decision and implementation". The pa- per also summaried the most popular evaluation methods and issues affecting plan implementation based on the evolution of evaluation theories, and proposed ideas for future studies.%区域规划作为统筹区域资源,协调区域发展的重要手段日益受到重视。而实际上,区域规划在实施阶段却面临困境,已经确定的规划在实施过程中不断被修改甚至瓦解。规划在发挥更大作用的同时,也受到更多的批评。这是由于规划及其实施是一个长期过程,充满了种种

  3. Health effects and wind turbines: A review of the literature

    2011-09-01

    Full Text Available Abstract Background Wind power has been harnessed as a source of power around the world. Debate is ongoing with respect to the relationship between reported health effects and wind turbines, specifically in terms of audible and inaudible noise. As a result, minimum setback distances have been established world-wide to reduce or avoid potential complaints from, or potential effects to, people living in proximity to wind turbines. People interested in this debate turn to two sources of information to make informed decisions: scientific peer-reviewed studies published in scientific journals and the popular literature and internet. Methods The purpose of this paper is to review the peer-reviewed scientific literature, government agency reports, and the most prominent information found in the popular literature. Combinations of key words were entered into the Thomson Reuters Web of KnowledgeSM and the internet search engine Google. The review was conducted in the spirit of the evaluation process outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Results Conclusions of the peer reviewed literature differ in some ways from those in the popular literature. In peer reviewed studies, wind turbine annoyance has been statistically associated with wind turbine noise, but found to be more strongly related to visual impact, attitude to wind turbines and sensitivity to noise. To date, no peer reviewed articles demonstrate a direct causal link between people living in proximity to modern wind turbines, the noise they emit and resulting physiological health effects. If anything, reported health effects are likely attributed to a number of environmental stressors that result in an annoyed/stressed state in a segment of the population. In the popular literature, self-reported health outcomes are related to distance from turbines and the claim is made that infrasound is the causative factor for the reported effects, even though sound pressure

    Full Text Available Objective: To conduct a review of the literature on the possible neuropsychological deficits present in patients with panic disorder. Methods: We performed a systematic review and search of the PubMed, ISI and PsycInfo scientific databases, with no time limits, using the following key words: cognitive, function, panic, and disorder. Of the 971 articles found, 25 were selected and 17 were included in this review. The inclusion criterion was at least one neuropsychological assessment task in patients with panic disorder. Results: The number of publications has grown gradually, especially those assessing executive functions, corresponding to the neurobiological model most widely accepted. Of all the functions evaluated, these patients had lower performance in memory tasks and higher performance in affective processing tasks related to the disorder. However, these data require further investigation due to the high rate of comorbidities, the small sample sizes of the included studies and little standardization of instruments used. Conclusion: The results showed a greater occurrence of deficits in memory and enhanced affective processing related to panic disorder.

    Full Text Available Literature review is one major component of a thesis, in which researchers connect the relationships of the related research to support the making of the research context at hand. Through critical reading, researchers understand the core concepts and being able to compare, contrast, and compose the new main themes of the literatures into thesis writing. Being able to write a good literature review is vital not only to show researchers’ own understanding of the field but also to support the creative research design. In order to understand the phenomenon of the literature reviews, particularly the work done by the Master theses, three research questions are raised: (1 what types of literature review are applied? (2 What mental strategies of literature review are used? And (3 what kinds of logic are employed in literature review? Content analysis is used in this study. Five theses with 106 analysis units are selected and analyzed. A recursive approach is processed in building the coding scheme. The research results reveal eight types of literature review, including contextual, definitional, historical, cut-in point, methodological, supportive, theoretical, empirical; six mental strategies, including analytical and judgmental, comparison, classification and induction, inductive and conclusive, standpoint of one’s own study, extensive; four kinds of writing logic, including integrated discursive, a lack of synthesis within literature, a lack to responsive to the main point, piling up of literature; and five kinds of innovative writing, including reframing, innovative reconceptualization, expansion on the thinking dimension, leading out the importance of the study, pointing out new cut-in point. The study suggests that better utilization of mental strategy and logic employment can further enhance integration of various literatures and thus framing a stronger context of the study. pp.4-25

Medical nutrition is regulated by a specific bill in Europe and in the US, with specific legislation and guidelines, and is provided to patients with special nutritional needs and indications for nutrition support. Therefore, medical nutrition products are delivered by medical prescription and supervised by health care professionals. Although these products have existed for more than 2 decades, health economic evidence of medical nutrition interventions is scarce. This research assesses the current published health economic evidence for medical nutrition by performing a systematic literature review related to health economic analysis of medical nutrition. Methods: A systematic literature search was done using standard literature databases, including PubMed, the Health Technology Assessment Database, and the National Health Service Economic Evaluation Database. Additionally, a free web-based search was conducted using the same search terms utilized in the systematic database search. The clinical background and basis of the analysis, health economic design, and results were extracted from the papers finally selected. The Drummond checklist was used to validate the quality of health economic modeling studies and the AMSTAR (A Measurement Tool to Assess Systematic Reviews checklist was used for published systematic reviews. Results: Fifty-three papers were identified and obtained via PubMed, or directly

    Purpose - The purpose of this study is to describe the characteristics of management and leadership competence of health-care leaders and managers, especially in the hospital environment. Health-care leaders and managers in this study were both nursing and physician managers. Competence was assessed by evaluating the knowledge, skills, attitudes and abilities that enable management and leadership tasks. Design/methodology/approach - A systematic literature review was performed to find articles that identify and describe the characteristics of management and leadership competence. Searches of electronic databases were conducted using set criteria for article selection. Altogether, 13 papers underwent an inductive content analysis. Findings - The characteristics of management and leadership competence were categorized into the following groups: health-care-context-related, operational and general. Research limitations/implications - One limitation of the study is that only 13 articles were found in the literature regarding the characteristics of management and leadership competence. However, the search terms were relevant, and the search process was endorsed by an information specialist. The study findings imply the need to shift away from the individual approach to leadership and management competence. Management and leadership need to be assessed more frequently from a holistic perspective, and not merely on the basis of position in the organizational hierarchy or of profession in health care. Originality/value - The authors' evaluation of the characteristics of management and leadership competence without a concentrated profession-based approach is original. PMID:26764963

  1. Chemistry of the redox sensitive elements. Literature review

    International Nuclear Information System (INIS)

    As a part of the safety assessment for a nuclear waste repository, the migration of the radioactive elements from the waste matrix to the biosphere has to be modelled. The geosphere is an important barrier and a consideration of the retention of the radioactive isotopes needs knowledge of sorption coefficients and solubilities. Important long-lived isotopes in the high level radioactive waste are the fission products selenium, technetium, palladium and tin, and the actinide neptunium, which are all redox sensitive elements. A transport model using conservative sorption values predicts mainly doses from these five elements. Since the individual oxidation states of the redox sensitive elements have different and largely unknown sorption properties and solubilities, the realistic doses might be far less. The relevant literature about the chemistry of the five elements is summarized and is planned to serve as the basis for an experimental programme. For every element, the literature about the general chemistry, selected sorption studies, geochemistry, and analytical methods is reviewed. It was found that the knowledge about some of these points is very limited. Even the general chemistry of some of the elements is not well known, because they have only limited applications and research concentrates only on certain aspects. Most of the sorption studies in the context of nuclear waste concentrate on a few of the relevant elements and others have been neglected up to now. The simulation of a realistic system in the laboratory poses some problems, which have to be solved as well. The literature about this subject is also critically reviewed. The elements which are most mobile under realistic far-field conditions are identified and it is recommended to concentrate research on these at the beginning. (author)

  3. Vulnerabilities—bibliometric analysis and literature review of evolving concepts

    Giupponi, Carlo; Biscaro, Claudio

    2015-12-01

    In this work we analyse the evolution of the vulnerability concept in the research streams of climate change adaptation (CCA) and disaster risk reduction (DRR). We combine a traditional literature review with data mining procedures applied to bibliographic databases to reconstruct the history of the concept within various research topics, showing its evolution and convergences over time. To do that, we integrate different methods combining machine learning algorithms with network and cluster analyses to examine a set of 3757 articles, analysing their distinctive features and similarities on the basis of their contents as well as co-authorships. Bibliometric analyses enable the identification of different communities of articles, pinpointing key papers and authors, while literature review makes it possible to assess the concept of vulnerability evolved within and beyond research communities and scientific networks. Moreover, this work examines the role played by documents published by UN institutions (UNDRO, UNISDR, IPCC) in contributing to the evolution of vulnerability and related concepts. Results show that signs of convergence are evident between the two research streams, and that the IPCC reports have played a major role in proposing solutions for unifying definitions of vulnerability. We observe that the phases of preparation of the IPCC reports are very rich in methodological and terminological developments, while after publication, the literature shows evident signs of propagation of the proposed concepts. The DRR research stream developed before the research stream on CCA, but the latter flourished rapidly and became much larger in terms of number of publications. Nevertheless, in terms of contents, adaptation studies and the IPCC have shown increasing adoption of the concepts developed within the disaster research stream, in particular with regard to the interpretation of vulnerability as one of the dimensions of risk.

    International Nuclear Information System (INIS)

    During the period 1972-1991, The United States Congress passed stringent environmental statues which the Environment Protection Agency implemented via regulations. The statues and regulations contain severe civil and criminal penalties. Civil violations resulted in fines, typically payable by the company. The act of willfully and knowingly violating the permit conditions or regulations can result in criminal charges being imposed upon the responsible part, i.e., either the company or individual. Criminal charges can include fines, lawyer fees, court costs and incarceration. This paper describes steps necessary to form an effective Environmental Compliance Assessment Review [CAR] program, train field and engineering personnel and perform a CAR audit.

    Dental identification assumes a primary role in the identification of remains when postmortem changes, traumatic tissue injury, or lack of a fingerprint record invalidate the use of visual or fingerprint methods. The most common role of the forensic dentist is the identification of deceased individuals. Forensic identification based on assessment of prosthodontic appliances is assuming greater significance, as labeling of dentures and other prosthetic appliance could provide vital clues for patient identification. Various recommendations have been made concerning the importance of denture identification. This paper presents a review of available literature highlighting the fact that how a prosthodontist can play a key role in identification of a deceased individual if trained to do so. PMID:25177136

  7. Surface and subsurface conditions in permafrost areas - a literature review

    International Nuclear Information System (INIS)

    This report contains a summary of some of the information within existing technical and scientific literature on permafrost. Permafrost is viewed as one of the future climate driven process domains that may exist in Scandinavia, and that may give rise to significantly different surface and subsurface conditions than the present. Except for changes in the biosphere, permafrost may impact hydraulic, mechanical, and chemical subsurface processes and conditions. Permafrost and its influences on the subsurface conditions are thus of interest for the performance and safety assessments of deep geological waste repositories. The definition of permafrost is 'ground that stays at or below 0 deg C for at least two consecutive years'. Permafrost will effect the geological subsurface to some depth. How deep the permafrost may grow is a function of the heat balance, thermal conditions at the surface and within the ground, and the geothermal heat flux from the Earth's inner parts. The main chapters of the report summaries the knowledge on permafrost evolution, occurrence and distribution, and extracts information concerning hydrology and mechanical and chemical impacts due to permafrost related conditions. The results of a literature review are always dependent on the available literature. Concerning permafrost there is some literature available from investigations in the field of long-term repositories and some from mining industries. However, reports of these investigations are few and the bulk of permafrost literature comes from the science departments concerned with surficial processes (e.g. geomorphology, hydrology, agriculture, etc) and from engineering concerns, such as foundation of constructions and pipeline design. This focus within the permafrost research inevitably yields a biased but also an abundant amount of information on localised surficial processes and a limited amount on regional and deep permafrost characteristics. Possible conclusions are that there is

    Full Text Available Objectives – The purpose of this review is to examine the development of embedded librarianship, its multiple meanings, and activities in practice. The review will also report on published outcomes and future research needs of embedded librarian programs.Methods – A search of current literature was conducted and summarized searching PubMed, CINAHL, Library, Information Science & Technology Abstracts (EBSCO, Academic Search Complete, and ERIC (EBSCO through August 23, 2012. Articles wereselected for inclusion in the review if they reported research findings related to embedded librarianship, if they provided unique case reports about embedded librarian programs, or if they provided substantive editorial comments on the topic. Relevant study findings were assessed for quality and presented in tabular and narrative form.Results – Currently, there is disparity in how embedded librarianship is being definedand used in common practice, ranging from embedding an online component into asingle course to full physical and cultural integration into an academic college orbusiness unit of an organization. Activities of embedded librarians include creatingcourse integrated instruction modules for either face-to-face or online courses, providingin depth research assistance to students or faculty, and co-locating within colleges orcustomer units via office hours for a few hours to all hours per week. Several case reports exist in the recent literature. Few high quality research studies reporting outcomes of librarians or library programs labeled as embedded exist at this point. Some evidence suggests that embedded librarians are effective with regards to student learning of information literacy objectives. Surveys suggest that both students and faculty appreciate embedded librarian services.Conclusion – Most published accounts discuss librarians embedding content and ready access to services in an online course management system.

    Full Text Available This paper discusses the concept of continuous improvement (CI by looking beyond what traditionally highlighted in literature concerning continuous improvement or Total Quality Management (TQM. The primary argument put forwarded in the discussion is that despite the undeniable positive results from CI practices, the way these activities are implemented, however, will lead to most programs becoming self-limiting. It needs to be asserted here that this paper is not intended to despise CI, rather, its purpose is limited only to provide a balance on the prevailing positive views toward CI.

Education is an important factor of development but it must be tailored to meet the needs of the target group. In developing countries one of the main barriers to women development is early marriage, which prevents further education, physical growth and power of decision; thus leads to more disparities between men and women. The interpretation of religious beliefs is another factor that legitimates inequalities; organizations have to understand its meaning and find ways to implement development programs in faith-based environments. They also have to advocate change in institutions that sustain disparities for the creation of unbiased policies.

  10. Asphalt solar collectors: A literature review

    International Nuclear Information System (INIS)

    Highlights: ► Solar energy can be harnessed by asphalt pavements. ► Research on asphalt thermal behavior and asphalt solar collectors is reviewed. ► Asphalt temperature is very sensitive to the variation of absortivity. ► Asphalt solar collector efficiency depends on flow rate and geometrical parameters. -- Abstract: Asphalt pavements subject to solar radiation can reach high temperatures causing not only environmental problems such as the heat island effect on cities but also structural damage due to rutting or hardening as a result of thermal cycles. Asphalt solar collectors are doubly effective active systems: as they solve the previously mentioned problems and, moreover, they can harness energy to be used in different applications. The main findings of the existing research on asphalt solar collectors are gathered together in this review paper. Firstly, the main heat transfer mechanisms involved in the solar energy collection process are identified and the most important parameters and variables are presented. After analyzing the theoretical foundations of the heat transfer process, this review focuses on the types of studies carried out so far on asphalt’s thermal behavior, different methodologies employed by other authors to study asphalt solar collectors and influence of the variables involved in thermal energy harvesting.

  11. Creating Value through Virtual Teams: A Current Literature Review

    2014-11-01

    Full Text Available Globally, virtual teams (VT as ICT-enabled emergent network organisation forms have gained international validity by innovative organisations, with a corresponding surge of interest in understanding how organisations can leverage VT to create business value. Despite growing deliberations in VT literature on managing VT, tasks and outcomes, however, creating business value through VT remains an unresolved theoretical and pragmatic conundrum. A review of prior relevant literature is essential to advancing knowledge. The paucity of published review articles seems to have impeded the field’s accumulation of VT knowledge. This research, therefore, reviews the current literature on case studies of VT to address the question: What are organisational challenges in creating business value through VT in the organisation? The key challenges found in the literature are effective communication, knowledge sharing, trust, and interpersonal skills in the new virtual boundary-less environment. Drawing on the IT business value model, we also discuss their resource-based implications.

    The use of antimicrobial substances has contributed to the development of multiple antimicrobial resistances (1), challenging the pharmaceutical industry to develop with new, innovative, and effective molecules. Discovered around 1980, molecules called natural antimicrobial peptides (AMPs) appear to hold great potential for the treatment of infections. These cationic peptides are able to stop the bacterial development and to control infections. The purpose of this review is to help improve the understanding of the way AMPs operate in the context of the development of new cures against viruses, bacteria, and mushrooms found in the human body in general and in the oral cavity in particular.

    Ten Berg, Paul W; Drijkoningen, Tessa; Strackee, Simon D; Buijze, Geert A

    2016-05-01

    Background In the lack of consensus, surgeon-based preference determines how acute scaphoid fractures are classified. There is a great variety of classification systems with considerable controversies. Purposes The purpose of this study was to provide an overview of the different classification systems, clarifying their subgroups and analyzing their popularity by comparing citation indexes. The intention was to improve data comparison between studies using heterogeneous fracture descriptions. Methods We performed a systematic review of the literature based on a search of medical literature from 1950 to 2015, and a manual search using the reference lists in relevant book chapters. Only original descriptions of classifications of acute scaphoid fractures in adults were included. Popularity was based on citation index as reported in the databases of Web of Science (WoS) and Google Scholar. Articles that were cited <10 times in WoS were excluded. Results Our literature search resulted in 308 potentially eligible descriptive reports of which 12 reports met the inclusion criteria. We distinguished 13 different (sub) classification systems based on (1) fracture location, (2) fracture plane orientation, and (3) fracture stability/displacement. Based on citations numbers, the Herbert classification was most popular, followed by the Russe and Mayo classifications. All classification systems were based on plain radiography. Conclusions Most classification systems were based on fracture location, displacement, or stability. Based on the controversy and limited reliability of current classification systems, suggested research areas for an updated classification include three-dimensional fracture pattern etiology and fracture fragment mobility assessed by dynamic imaging.

  8. Radiation Oncology in Undergraduate Medical Education: A Literature Review

    International Nuclear Information System (INIS)

    Purpose: To review the published literature pertaining to radiation oncology in undergraduate medical education. Methods and Materials: Ovid MEDLINE, Ovid MEDLINE Daily Update and EMBASE databases were searched for the 11-year period of January 1, 1998, through the last week of March 2009. A medical librarian used an extensive list of indexed subject headings and text words. Results: The search returned 640 article references, but only seven contained significant information pertaining to teaching radiation oncology to medical undergraduates. One article described a comprehensive oncology curriculum including recommended radiation oncology teaching objectives and sample student evaluations, two described integrating radiation oncology teaching into a radiology rotation, two described multidisciplinary anatomy-based courses intended to reinforce principles of tumor biology and radiotherapy planning, one described an exercise designed to test clinical reasoning skills within radiation oncology cases, and one described a Web-based curriculum involving oncologic physics. Conclusions: To the authors' knowledge, this is the first review of the literature pertaining to teaching radiation oncology to medical undergraduates, and it demonstrates the paucity of published work in this area of medical education. Teaching radiation oncology should begin early in the undergraduate process, should be mandatory for all students, and should impart knowledge relevant to future general practitioners rather than detailed information relevant only to oncologists. Educators should make use of available model curricula and should integrate radiation oncology teaching into existing curricula or construct stand-alone oncology rotations where the principles of radiation oncology can be conveyed. Assessments of student knowledge and curriculum effectiveness are critical.

  10. Irradiation preservation of seafood: Literature review

    International Nuclear Information System (INIS)

    The application of gamma-irradiation for extending the shelf life of seafood has been of interest for many years. This report reviews a number of studies on seafood irradiation conducted over the past several years. Topics covered include seafood irradiation techniques and dosages, species applicability and differences, the effects of packaging on seafood preservation, and changes in organoleptic acceptability as a result of irradiation. Particular attention is given to radiation effects (likely and unlikely) of concern to the public. These include the potential for generation of toxic chemical products, botulinum toxin production, and other health concerns. No scientifically defensible evidence of any kind was found for any harmful effect of irradiation of seafoods at the doses being considered (less than 300 krad), and all indications are that irradiation is an acceptable and needed additional tool for seafood preservation. 49 refs., 14 figs., 14 tabs

    Full Text Available The hyper-immunoglobulin E (IgE syndromes (HIES are primary immunodeficiencies characterized by the recurrent staphylococcal abscesses, recurrent pneumonia and highly elevated serum IgE levels. There are two forms of HIES: a dominant form (AD-HIES and a recessive form (AR-HIES. AD form of HIES is caused by mutations in STAT3 and the AR form is caused by mutations in DOCK8 and TYK2. These syndromes have different clinical presentations and outcomes. AD-HIES is a multisystem disorder that includes abnormalities of the skin, lungs, musculo-skeletal system and dental system. In contrast, these symptoms in patients with AR-HIES are missing. AR-HIES patients have severe viral infections and may develop neurological complications. This review article discusses the clinical presentation and laboratory findings in both forms of HIES, as well as the establishment of diagnose, inheritance, molecular genetics and immunological abnormalities of HIES.

Methods : I reviewed and analyzed all the theses published in Domestic and Foreign research institution from 1990 to 2009. Results : The following results were obtained in this study. 1. Analyzed number of theses published, there was no significance per year. 2. Classified by theme of journal, journals related to surgery were most(41 journals, 75.92% among 54 kinds. 3. Classified by theses by research method and thesis types, case report accounted for nearly twothirds (52 pieces, 68.42% of all theses and consideration of document was next(9 pieces, 11.84%. 4. With the most case of venous congestion after plastic and reconstructive surgery(33 pieces, 63.46%, leech therapy was effective on illnesses such as haematoma, macroglossia, purpura, varicous vein, avulsion injury, neurovascular compression, diabetic neuropathy, penoscrotal oedema, buerger's disease, rheumatoid arthritis. 5. Two most appeared adverse effects were anemia and infection. Immediate blood transfusion was done for recovering anemia and prophylactic 3rd generation antibiotics to infection were emphasized in more than half of case reports. 6. All of consideration of documents was retrospective study of cases related leech therapy and 3 pieces of them emphasized prophyratic antibiotic treatment for preventing infection. 7. The study of clinical trail type started first in 2002 and osteoarthritis of knee and carpometacarpal joint were main target. As see above result, Leech therapy was effective cure and could be used in disease induced by venous congestion. And I think that it is necessary to perform additional study related to solution of problems about leech therapy and protocol for using in clinical practice.

    Background Fibrin sealants are widely used in neurosurgery to seal the suture line, provide watertight closure, and prevent cerebrospinal fluid leaks. The aim of this systematic review is to summarize the current efficacy and safety literature of fibrin sealants in dura sealing and the prevention/treatment of cerebrospinal fluid leaks. Methods A comprehensive electronic literature search was run in the following databases: Cochrane Database of Systematic Reviews, Cochrane Central Resister of Controlled Trials, clinicaltrials.gov, MEDLINE/PubMed, and EMBASE. Titles and abstracts of potential articles of interest were reviewed independently by 3 of the authors. Results A total of 1006 database records and additional records were identified. After screening for duplicates and relevance, a total of 78 articles were assessed by the investigators for eligibility. Thirty-eight were excluded and the full-text of 40 articles were included in the qualitative synthesis. Seven of these included only safety data and were included in the safety assessment. The remaining 33 articles included findings from 32 studies that enrolled a total of 2935 patients who were exposed to fibrin sealant. Among these 33 studies there were only 3 randomized controlled trials, with the remaining being prospective cohort analysis, case controlled studies, prospective or retrospective case series. One randomized controlled trial, with 89 patients exposed to fibrin sealant, found a greater rate of intraoperative watertight dura closure in the fibrin sealant group than the control group (92.1% versus 38.0%, p0.05). Other clinical trials evaluated the effect of fibrin sealant in the postoperative prevention of cerebrospinal fluid leaks. These were generally lower level evidence studies (ie, not prospective, randomized, controlled trials) that were not designed or powered to demonstrate a significant advantage to fibrin sealant use. Two small case series studies evaluated the effect of fibrin sealants

    Asynclitism is defined as the "oblique malpresentation of the fetal head in labor". Asynclitism is a clinical diagnosis that may be difficult to make; it may be found during vaginal examination. It is significant because it may cause failure of progress operative or cesarean delivery. We reviewed all literature for asynclitism by performing an extensive electronic search of studies from 1959 to 2013. All studies were first reviewed by a single author and discussed with co-authors. The following studies were identified: 8 book chapters, 14 studies on asynclitism alone and 10 papers on both fetal occiput posterior position and asynclitism. The fetal head in a laboring patient may be associated with some degree of asynclitism; this is seen as usual way of the fetal head to adjust to maternal pelvic diameters. However, marked asynclitism is often detected in presence of a co-existing fetal head malposition, especially the transverse and occipital posterior positions. Digital diagnosis of asynclitism is enhanced by intrapartum ultrasound with transabdominal or transperineal approach. The accurate diagnosis of asynclitism, in an objective way, may provide a better assessment of the fetal head position that will help in the correct application of vacuum and forceps, allowing the prevention of unnecessary cesarean deliveries.

    2016-01-01

    The aim of the current literature review, which is based on 64 empirical studies, was to assess to what extent mechanisms of the Social Information Processing (SIP) model of Crick and Dodge (1994) are related to victimization. The reviewed studies have provided support for the relation between victimization and several social information processing mechanisms, especially the interpretation of cues and self-efficacy (as part of the response decision). The relationship between victimization and other mechanisms, such as the response generation, was only studied in a few articles. Until now research has often focused on just one step of the model, instead of attempting to measure the associations between multiple mechanisms and victimization in multivariate analyses. Such analyses would be interesting to gain more insight into the SIP model and its relationship with victimization. The few available longitudinal studies show that mechanisms both predict victimization (internal locus of control, negative self-evaluations and less assertive response selection) and are predicted by victimization (hostile attribution of intent and negative evaluations of others). Associations between victimization and SIP mechanisms vary across different types and severity of victimization (stronger in personal and severe victimization), and different populations (stronger among young victims). Practice could focus on these stronger associations and the interpretation of cues. More research is needed however, to investigate whether intervention programs that address SIP mechanisms are suitable for victimization and all relevant populations. PMID:25389278

    Full Text Available The prevalence of overweight and obesity in women has increased during the last decades. This is a serious concern since a high BMI before conception is an independent risk factor for many adverse outcomes of pregnancy. Therefore, dietary counseling, intended to stimulate weight loss in overweight and obese women prior to conception has recently been recommended. However, dieting with the purpose to lose weight may involve health risks for mother and offspring. We conducted a systematic literature review to identify papers investigating the effects of weight loss due to dietary interventions before conception. The objective of this study is to assess the effect of weight loss prior to conception in overweight or obese women on a number of health-related outcomes in mother and offspring using studies published between January 2000 and December 2011. Our first literature search produced 486 citations and, based on predefined eligibility criteria, 58 were selected and ordered in full text. Two group members read each paper. Fifteen studies were selected for quality assessment and two of them were considered appropriate for inclusion in evidence tables. A complementary search identified 168 citations with four papers being ordered in full text. The two selected studies provided data for overweight and obese women. One showed a positive effect of weight loss before pregnancy on the risk of gestational diabetes and one demonstrated a reduced risk for large-for-gestational-age infants in women with a BMI above 25 who lost weight before pregnancy. No study investigated the effect of weight loss due to a dietary intervention before conception. There is a lack of studies on overweight and obese women investigating the effect of dietary-induced weight loss prior to conception on health-related variables in mother and offspring. Such studies are probably lacking since they are difficult to conduct. Therefore, alternative strategies to control the body

    The aim of this study was to synthesize research on female street level prostitutes for application in mental health practice and identification of future research needs. The data were from reports conducted in Westernized countries on female street level prostitutes between the years 2000 and 2014. Street level prostitutes are at high risk for HIV/STIs, chronic and acute physical/mental health problems, and violence, but there is a paucity of research on resilience and coping skills. We conclude that street level prostitutes suffer severe health disparities, yet they do not seek health care on a consistent basis. It is important for mental healthcare providers to offer women a safe, non-judgmental environment while providing assessment and referral. Future research on mental health consequences as well as resilience and coping skills would support effective interventions that address the women holistically. PMID:26379130

    Dental anxiety is very common, affecting 22% of the population. One way to increase access to dental care is by the use of BDZs in conscious sedation. These drugs are known to be safe when titrated. BDZs work by stimulating GABAA receptors within inhibitory pathways of the CNS. A consequence of this is a reduction in respiratory drive. Thus assessing saturation of peripheral oxygen (SpO2) is mandatory. A pulse oximeter is normally used to do this. However a pulse oximeter cannot detect changes in CO2 which could result from a reduction in ventilatory drive. Many practitioners prescribe supplemental oxygen to compensate for hypoventilation, which can inhibit the ability of pulse oximetry to detect hypoventilation. Transcutaneous CO2 monitoring is currently used in ICUs and neonatal units. It may, however, have a place in conscious sedation dentistry. It can be used to detect changes in CO2, and is not affected by supplemental oxygen. PMID:24984664

    Full Text Available Abstract Abetalipoproteinemia (ABL, OMIM 200100 is a rare, autosomal recessive disorder, characterized by fat malabsorption, acanthocytosis and hypocholesterolemia in infancy. Later in life, deficiency of fat-soluble vitamins is associated with development of atypical retinitis pigmentosa, coagulopathy, posterior column neuropathy and myopathy. ABL results from mutations in the gene encoding the large subunit of microsomal triglyceride transfer protein (MTP; OMIM 157147. To date at least 33 MTP mutations have been identified in 43 ABL patients. We describe the clinical progress of two patients, both currently in the fifth decade of life, who were diagnosed with ABL as children and were treated with high oral doses of fat soluble vitamins, including vitamin E over the last three decades. Treatment appears to have been associated with arrest of the neuropathy and other complications in both patients. Because pharmacologic inhibition of MTP is being developed as a novel approach to reduce plasma cholesterol for prevention of cardiovascular disease, defining the long-term clinical features of patients with a natural deficiency in MTP might provide some insight into the possible effects of such treatments. We review the range of clinical, biochemical and molecular perturbations in ABL.

    1979-06-01

    A review and analysis of 115 surveys of the general population between 1973 and 1978 (before the Three Mile Island accident, sudden gasoline price increases, and spot gasoline shortages) are presented. The survey data are organized and analyzed according to a set of categories described in Chapter 2. The public's definition of the energy situation is the focus of Chapter 3. Chapter 4 describes public opinion concerning energy conservation pertaining to transportation and domestic energy use -- whether it is efficacious, how knowledgeable people are about conservation, whether they favor it, and whether they engage in it. Findings on the solar energy alternative are described in Chapter 5. Public opinion concerning more conventional sources of energy -- oil and natural gas, coal, and nuclear energy -- are discussed in Chapter 6. In Chapter 7, a summary of analytical findings by 10 major sociodemographic characteristics is presented. Chapter 8 describes analytical findings using various social-psychological variables. A summary is presented in Chapter 9.

    Full Text Available Pancreaticoduodenectomy (PD is considered the gold standard treatment for periampullory carcinomas. This procedure presents 30%–40% of morbidity. Patients who have undergone pancreaticoduodenectomy often present perioperative malnutrition that is worse in the early postoperative days, affects the process of healing, the intestinal barrier function and the number of postoperative complications. Few studies focus on the relation between enteral nutrition (EN and postoperative complications. Our aim was to perform a review, including only randomized controlled trial meta-analyses or well-designed studies, of evidence regarding the correlation between EN and main complications and outcomes after pancreaticoduodenectomy, as delayed gastric emptying (DGE, postoperative pancreatic fistula (POPF, postpancreatectomy hemorrhage (PPH, length of stay and infectious complications. Several studies, especially randomized controlled trial have shown that EN does not increase the rate of DGE. EN appeared safe and tolerated for patients after PD, even if it did not reveal any advantages in terms of POPF, PPH, length of stay and infectious complications.

  8. Coprecipitation of radionuclides: basic concepts, literature review and first applications

    Energy Technology Data Exchange (ETDEWEB)

    1997-11-01

    Coprecipitation of radionuclides with solid products is currently not analysed quantitatively in safety assessments for nuclear waste repositories, although this process is thought to be an important mechanism for limiting nuclide concentrations in solution. This is due to the fact that neither the solid phases controlling coprecipitation nor the parameter values necessary to describe this process are known sufficiently. This introductory report provides basic knowledge on this subject and a review of experimental data from the literature. Emphasis is placed on experiments of trace metal coprecipitation with calcite, because this mineral is a dominating alteration product of cement in the Swiss L/ILW repository. This resulted in a database of partition coefficients, which allow to describe empirically the distribution of trace elements between calcite and solution and thus to quantify coprecipitation processes. Since laboratory data on coprecipitation with calcite are lacking for many safety-relevant radioelements, their partition coefficients were inferred with the help of estimation techniques. Such techniques rely on empirical correlations, which relate the uptake of trace metals in calcite (measured in laboratory tests) with selected chemical properties of the coprecipitated metals (e.g. ionic radius, sorption properties, solubility products of the pure trace metal carbonates). The combination of these correlations with independent geochemical evidence allows the extrapolation of radioelement-specific partition coefficients, which are then used for the quantitative modelling. In a first step the potential role of radionuclide coprecipitation during cement degradation in the L/ILW repository planned at Wellenberg is assessed. (author) figs., tabs., refs.

    2016-08-01

    The Mental Capacity Act (MCA) is a piece of statutory legislation which is designed to empower and protect those who are assessed as being unable to make decisions for themselves. At the time of implementation, the legislation was described as visionary and it had the potential to change the lives of many. However, a post-legislative scrutiny report published in 2014 concluded that there is a lack of knowledge among professionals of the MCA, and so it is not embedded into daily clinical practice. This review of literature has identified four key themes: assessment, training, knowledge and empowerment. These appear to concur with the findings of the House of Lords report. The successful integration of the MCA into professionals' everyday practice is high on the political agenda, thus reinforcing the message that following the guidance set out in the MCA legislation is mandatory and not a choice. A shift in culture and improvement in knowledge and understanding of the MCA is required in order for it to be used in the correct manner for which it was designed. PMID:27479855

  11. Assessment of Literature Related to Combustion Appliance Venting Systems

    In many residential building retrofit programs, air tightening to increase energy efficiency is often constrained by safety concerns with naturally vented combustion appliances. Tighter residential buildings more readily depressurize when exhaust equipment is operated, making combustion appliances more prone to backdraft or spill combustion exhaust into the living space. Several measures, such as installation guidelines, vent sizing codes, and combustion safety diagnostics, are in place with the intent to prevent backdrafting and combustion spillage, but the diagnostics conflict and the risk mitigation objective is inconsistent. This literature review summarizes the metrics and diagnostics used to assess combustion safety, documents their technical basis, and investigates their risk mitigations. It compiles information from the following: codes for combustion appliance venting and installation; standards and guidelines for combustion safety diagnostics; research evaluating combustion safety diagnostics; research investigating wind effects on building depressurization and venting; and software for simulating vent system performance.

  12. Campus Recreation Worldwide: A Literature Review

    2012-04-01

    Full Text Available The percentage of adults who engage in regular leisure time physical activity is decreasing, causing an increase in risk for several health issues. Research indicates that the more physically active individuals are in their leisure time as adolescents and young adults, the more likely they are to remain active throughout the lifespan. The number of individuals entering the college or university setting has continued to increase over the past decade. Institutions of higher education are supporting the construction and management of large recreational facilities on-campuses for college students to use for leisure time physical activity behaviors. Many administrators are aware of the benefits of participation in leisure time physical activity among college students including: higher grades, less stress, better adjustment and higher persistence to graduation. Given the increase in popularity of comprehensive campus recreation programs and facilities, there is a need for theory based research to bridge the gap in assessing participation and developing intervention and educational materials to increase participation.

    2012-10-01

    There is a growing interest in diagnosis based on the analysis of saliva. This is a simple, non-invasive method of obtaining oral samples which is safe for both the health worker and the patient, not to mention allowing for simple and cost-efficient storage. The majority of studies use general saliva samples in their entirety, complex fluids containing both local and systemic sources and whose composition corresponds to that of the blood. General saliva contains a considerable amount of desquamated epithelial cells, microorganisms and remnants of food and drink; it is essential to cleanse and refine the saliva samples to remove any external elements. Immediate processing of the sample is recommended in order to avoid decomposition, where this is not possible, the sample may be stored at -80ºC. Salivary analysis - much the same as blood analysis - aims to identify diverse medication or indications of certain diseases while providing a relatively simple tool for both early diagnosis and monitoring various irregularities. The practicalities of salivary analysis have been studied in fields such as: viral and bacterial infections, autoimmune diseases (like Sjögren's syndrome and cɶliac disease), endocrinopathies (such as Cushing's syndrome), oncology (early diagnosis of breast, lung and stomach carcinoma and oral squamous cell carcinoma), stress assessment, medication detection and forensic science among others. It is hoped that salivary analysis, with the help of current technological advances, will be valued much more highly in the near future. There still remain contradictory results with respect to analytic markers, which is why further studies into wider-ranging samples are fundamental to prove its viability. Key words:Saliva, biomarkers, early diagnosis. PMID:24558562

    Full Text Available AbstractObjective:The present study was aimed at reviewing the literature to identify solutions for problems observed in radiology services.Materials and Methods:Basic, qualitative, exploratory literature review at Scopus and SciELO databases, utilizing the Mendeley and Illustrator CC Adobe softwares.Results:In the databases, 565 papers – 120 out of them, pdf free – were identified. Problems observed in the radiology sector are related to procedures scheduling, humanization, lack of training, poor knowledge and use of management techniques, and interaction with users. The design management provides the services with interesting solutions such as Benchmarking, CRM, Lean Approach, ServiceBlueprinting, continued education, among others.Conclusion:Literature review is an important tool to identify problems and respective solutions. However, considering the small number of studies approaching management of radiology services, this is a great field of research for the development of deeper studies.

  1. The paradox of imaging technology: A review of the literature

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to review the social scientific literature associated with medical imaging technology. Methods: An extensive search of published studies in nursing, psychology and anthropology was undertaken to support the radiography specific literature. Results: Following a broad definition of technology and its profound influence on society, an analysis of imaging literature revealed a complex relationship between technology and human interactions. Examples are cited for CT, MRI and ultrasound. Conclusion: It is suggested that any attempt to understand imaging technology must place at its centre the perspectives of patients and radiographers. Scientific descriptors must be balanced with equal deliberation given to 'soft technology'

    Ratz, Joan M.; Conk, Shannon J.

    2010-01-01

    The U.S. Fish and Wildlife Service National Conservation Training Center requested a literature review product that would serve as a resource to natural resource professionals interested in using webcams to connect people with nature. The literature review focused on the effects on the public of viewing wildlife through webcams and on information regarding installation and use of webcams. We searched the peer reviewed, published literature for three topics: wildlife cameras, virtual tourism, and technological nature. Very few publications directly addressed the effect of viewing wildlife webcams. The review of information on installation and use of cameras yielded information about many aspects of the use of remote photography, but not much specifically regarding webcams. Aspects of wildlife camera use covered in the literature review include: camera options, image retrieval, system maintenance and monitoring, time to assemble, power source, light source, camera mount, frequency of image recording, consequences for animals, and equipment security. Webcam technology is relatively new and more publication regarding the use of the technology is needed. Future research should specifically study the effect that viewing wildlife through webcams has on the viewers' conservation attitudes, behaviors, and sense of connectedness to nature.

  9. Valproate-Associated Parkinsonism: A Critical Review of the Literature.

    Science.gov (United States)

    Brugger, Florian; Bhatia, Kailash P; Besag, Frank M C

    2016-06-01

    Valproate was first approved as an antiepileptic drug in 1962 and has since also become established as a mood stabiliser and as prophylaxis for migraine. In 1979, Lautin published the first description of a valproate-associated extrapyramidal syndrome. Many cases of valproate-associated parkinsonism have subsequently been published, but uncertainties remain concerning its prevalence, risk factors and prognosis. The aim of this paper is to provide a critical review of the existing literature on valproate-associated parkinsonism and to discuss possible mechanisms. Literature databases were searched systematically: we identified a total of 116 patients with valproate-associated parkinsonism published in case reports, case series and systematic analyses. Prevalence rates ranged widely, between 1.4 and 75 % of patients taking valproate. There was great heterogeneity with regard to clinical presentation, age of onset, valproate dose, concomitant conditions and imaging findings. In all patients apart from three, valproate plasma concentrations were within or even below the recommended reference range when the parkinsonism occurred. Parkinsonism was reversible in the majority of patients, although recovery was often prolonged and sometimes incomplete. A dopaminergic deficit was confirmed in three of six patients investigated with dopamine transporter imaging. Seven of 14 patients who were treated with dopaminergic medication had a good response. The quality of the evidence was assessed and probability of causation was examined using the Naranjo score, which ranged from 0 to 7 (median: 5.0). Several pathophysiological mechanisms, including altered gene expression and neurotransmitter signalling, enhanced neurodegeneration or unmasking subclinical dopaminergic degeneration, could theoretically lead to valproate-associated parkinsonism. Further studies are warranted to elucidate this entity and its underlying pathophysiology. PMID:27255404

    Directory of Open Access Journals (Sweden)

    Negrea Laura Georgeta

    2011-12-01

    Full Text Available The present study has as main objective to reflect the state of literature regarding free cash flow, and to withdraw the main pro's and con's in order to create an objective image upon this indicator. The main idea generating this research was the growing interest on cash flow reporting. As many say, 'Cash Flow is King', while in Anglo Saxon countries the interest of investors and analysts in concentrated on operating cash flow, as the most important indicator of the probability of bankruptcy. In this context, voluntary additional reporting, like free cash flow may come either as an aid in providing the fair view or as an opportunistically reported figure. Throughout the paper, the intention was to provide answers to three main research questions: What are the definition and calculation method of free cash flow? Why is there an interest in free cash flow reporting? What is the impact of free cash flow on the agency theory? In order to provide relevant conclusions, four international data basis were used, and related articles and studies were extracted. The results proved that there is no generally accepted definition and computing method, while the format depends on the end-user of the report (shareholders, investors, analysts, bankers, a.s.o.. As stated below, this aspect generates confusion and lack of comparability, giving room to creative accounting techniques. Moreover, the interest on free cash flow reporting is connected mainly to liquidity assessment, company valuation and investors choice. Still, in the context of agency theory, results show that in presence of high free cash flow, managers tend to make investment choices that satisfy their personal interest and that generate low efficiency and profitability for the company. The contribution to current state of research is providing a literature review study, focused on a comparative approach, as well as on underlying an objective image upon a debatable financial indicator and

    2016-06-01

    The expansion of biomedical literature is creating the need for efficient tools to keep pace with increasing volumes of information. Text mining (TM) approaches are becoming essential to facilitate the automated extraction of useful biomedical information from unstructured text. We reviewed the applications of TM in psychiatry, and explored its advantages and limitations. A systematic review of the literature was carried out using the CINAHL, Medline, EMBASE, PsycINFO and Cochrane databases. In this review, 1103 papers were screened, and 38 were included as applications of TM in psychiatric research. Using TM and content analysis, we identified four major areas of application: (1) Psychopathology (i.e. observational studies focusing on mental illnesses) (2) the Patient perspective (i.e. patients' thoughts and opinions), (3) Medical records (i.e. safety issues, quality of care and description of treatments), and (4) Medical literature (i.e. identification of new scientific information in the literature). The information sources were qualitative studies, Internet postings, medical records and biomedical literature. Our work demonstrates that TM can contribute to complex research tasks in psychiatry. We discuss the benefits, limits, and further applications of this tool in the future. Copyright © 2015 John Wiley & Sons, Ltd. PMID:26184780

    2014-06-01

    The careers of male and female physicians indicate gender differences, whereas in medical education a feminization is occurring. Our review aims to specify gender-related speciality preferences during medical education. A literature search on gender differences in medical students' speciality preferences was conducted in PubMed, Eric, Embase and Social Abstracts, and reference lists from January 2000 to June 2013. Study quality was assessed by critical appraisal. Our search yielded 741 hits and included 14, mostly cross-sectional, studies originating from various countries. No cohort studies were found. Throughout medical education, surgery is predominantly preferred by men and gynaecology, paediatrics and general practice by women. Internal medicine was pursued by both genders. The extent of gender-specific speciality preferences seemed related to the male-to-female ratio in the study population. When a population contained more male students gynaecology seemed even more preferred by women, while in a more feminine population, men more highly preferred surgery. Internationally, throughout medical education, gender-related speciality preferences are apparent. The extent might be influenced by the male-to-female ratio of a study population. Further research of the role of gender in career considerations of medical students on the future workforce is necessary. PMID:24980516

    2015-10-01

    Idiopathic pulmonary fibrosis (IPF) is associated with a fatal prognosis and manifests in patients over 60 years old who may have comorbidities. The prevalence and impact of comorbidities on the clinical course of IPF is unclear.This systematic literature review examined the prevalence of comorbidities and mortality associated with comorbidities in IPF patients. Relevant observational studies published in English from January 1990 to January 2015 identified via MEDLINE and EMBASE were included; bibliographies of articles were also searched.Among the 126 studies included, prevalence of pulmonary hypertension (PH) was 3-86%, 6-91% for obstructive sleep apnoea, 3-48% for lung cancer and 6-67% for chronic obstructive pulmonary disease (COPD). Nonrespiratory comorbidities included ischaemic heart disease (IHD) (3-68%) and gastro-oesophageal reflux (GER) (0-94%). Mortality was highest among patients with IPF and lung cancer. Most studies assessed relatively small samples of patients with IPF.PH, COPD, lung cancer, GER and IHD are significant comorbidities; differences in IPF severity, case definitions and patient characteristics limited the comparability of findings. The identification and prompt treatment of comorbidities may have a clinically significant impact on overall outcome that is meaningful for patients with IPF. PMID:26424523

  6. New minimally invasive approaches for cholecystectomy: Review of literature

    2015-01-01

    Laparoscopic cholecystectomy is the most commonlyperformed abdominal intervention in Western countries. In an attempt to reduce the invasiveness of the procedure, surgeons have developed single-incision laparoscopic cholecystectomy(SILC), minilaparoscopic cholecystectomy(MLC) and natural orifice transluminal endoscopic surgery(NOTES). The aim of this review was to determine the role of these new minimally invasive approaches for elective laparoscopic cholecystectomy in the treatment of gallstone related disease. Current literature remains insufficient for the correct assessment of emerging techniques for laparoscopic cholecystectomy. None of these procedures has demonstrated clear benefits over conventional laparoscopic cholecystectomy. SILC cannot be currently recommended as it can be associated with an increased risk of bile duct injury and incisional hernia incidence. NOTES cholecystectomy is still experimental, although hybrid transvaginal cholecystectomy is gaining popularity in clinical practice. As it is standardized and almost identical to the standard laparoscopic technique, MLC could lead to limited benefits without exposing patients to increased postoperative complications, being therefore adoptable for routine elective cholecystectomy. Technical challenges of SILC and NOTES cholecystectomy could be addressed with the evolution of new surgical tools that need to catch up with the innovative minds of surgeons. Regardless the place of these approaches in the future, robotization may be necessary to impose them as standard treatment.

  7. Text Messaging and Teenagers: A Review of the Literature

    2011-12-01

    Full Text Available Look around on any bus, in any restaurant, or standing in any line and people are text messaging. Likewise, most teenagers in America are nearly inseparable from their cell phones, not because they are constantly talking, but because they are connecting with their friends through text messaging. Although cell phones are banned in most K-12 schools, students are text messaging constantly there as well. Few adults, including teachers and administrators, understand how and why adolescents and young adults are using text messaging or how to harness text messaging capabilities in the classroom. This literature review examines the limited amount of research on the practice of text messaging for adolescents and young adults (ages 11-21, focusing on the motivation, means, and methods of text messaging. In addition, it considers how adults have successfully engaged text messaging to assess and inform youth about health-related issues. In this light, some current educational uses of text messaging are highlighted, along with implications for future research.

  8. A literature review of actinide-carbonate mineral interactions

    International Nuclear Information System (INIS)

    Chemical retardation of actinides in groundwater systems is a potentially important mechanism for assessing the performance of the Waste Isolation Pilot Plant (WIPP), a facility intended to demonstrate safe disposal of transuranic waste. Rigorous estimation of chemical retardation during transport through the Culebra Dolomite, a water-bearing unit overlying the WIPP, requires a mechanistic understanding of chemical reactions between dissolved elements and mineral surfaces. This report represents a first step toward this goal by examining the literature for pertinent experimental studies of actinide-carbonate interactions. A summary of existing models is given, along with the types of experiments on which these models are based. Articles pertaining to research into actinide interactions with carbonate minerals are summarized. Select articles involving trace element-carbonate mineral interactions are also reviewed and may serve as templates for future research. A bibliography of related articles is included. Americium(III), and its nonradioactive analog neodymium(III), partition strongly from aqueous solutions into carbonate minerals. Recent thermodynamic, kinetic, and surface studies show that Nd is preferentially removed from solution, forming a Nd-Ca carbonate solid solution. Neptunium(V) is rapidly removed from solution by carbonates. Plutonium incorporation into carbonates is complicated by multiple oxidation states. Little research has been done on the radium(H) and thorium(IV) carbonate systems. Removal of uranyl ion from solution by calcite is limited to monolayer surface coverage

    2014-01-01

    Full Text Available Kaitlyn P RolandCentre on Aging, University of Victoria, Victoria, BC, CanadaBackground: Yoga may be applicable to persons with Parkinson's disease (PD. The adaptability of yoga to suit varying abilities is of significance to the PD population with its progressive mobility problems. The additional psychosocial benefits of yoga are important to the quality of life. This systematic review presents scientific evidence pertaining to the impact of yoga on physical function and psychological well-being in PD.Methods: A literature search was conducted for randomized controlled trials (n=1, pretest–post-test design (n=3, and case studies (n=3 with the terms “yoga” and “Parkinson disease”. The study quality was assessed with a modified version of the Downs and Black Checklist and ranged from 8 to 16. The study outcomes included functional mobility (n=6, flexibility (n=4, balance (n=4, strength (n=4, depression (n=2, sleep (n=1, and quality of life (n=1.Results: The preliminary data suggested that yoga resulted in modest improvements in functional mobility, balance, and lower-limb strength in persons with PD. This has implications for gait, postural stability, balance confidence, and functional declines related to inactivity. An improved upper- and lower-body flexibility following yoga in persons with PD is applicable to rigidity, shuffling gait, and flexed posture. The presented evidence also showed positive outcomes for mood and sleep, demonstrating yoga's benefit for self-efficacy and social support.Conclusion: This review suggests that yoga provided an alternative method for addressing some of the reversible factors that impact motor function in PD, as well as contributing to an improved psychosocial well-being. However, limitations to the design of the studies necessitate further research to validate yoga as a therapy for PD.Keywords: alternative therapy, adaptable, mobility, mood, quality of life, neurological disorders

    Biagi, Roberto; Cossellu, Gianguido; Sarcina, Michele; Pizzamiglio, Ilaria Tina; Farronato, Giampietro

    2015-01-01

    Summary The purpose of this literature review was to evaluate the effectiveness of the laser-assisted treatment of dentinal hypersensitivity. A review with inclusion and exclusion criteria was performed from January 2009 to December 2014 with electronic data-bases: MedLine via PubMed, Science Direct and Cochrane Library. Research of paper magazines by hand was not considered. Forty-three articles were selected between literature reviews, in vitro studies, clinical trials, pilot and preliminary studies. The items were divided into laser-used groups for an accurate description, and then the reading of results into various typologies. Laser-assisted treatment reduces dentinal hypersensitivity-related pain, but also a psychosomatic component must be considered, so further studies and more suitable follow-ups are necessary.

    2012-06-01

    This current study's goal is to summarize the literature regarding Antenatal Depression (AD) in the East Asian countries of Taiwan, China (including Hong Kong and Macau), Japan, and Korea. The main search utilized a Pub med Chinese Electronic Periodical Service (CEPS) literature review using keywords 'AD', and 'Prenatal Depression' with searches for 'Japan', 'Korea', 'Taiwan', 'Hong Kong' and Macau'. The rates of AD in East Asia appear to be relatively close to those in the Western literature, although certain studies showed slightly decreased rates. Many of the risk factors for AD were the same in the Eastern and Western literature. These risk factors included demographic factors such as younger age, smoking, low education and income, and unemployment. Other risk factors were physical symptoms such as menstrual pains and nausea. Finally, psychological factors such as a poor response to the pregnancy, poor spousal support, and poor family support were associated with AD. With regard to treatment, there were no studies examining the administration of psychotropic medications for AD. The literature from East Asia both confirmed many Western findings and made unique contributions to the literature on AD. The treatment of AD in East Asia appears to be an entity which, despite its morbidity, has not been adequately studied. PMID:22707960

    Compared to the rich literature on Nazi medicine in general, the connection between dentists and National Socialism is less well documented. Neither the elites of the field from this era nor those excluded from the profession are catalogued in a systematic manner. The aims of this contribution are to assemble and review the relevant literature and show how German dentistry organizations have handled this chapter of their professional history. Trends in the literature since the 1980s are examined and it is pointed out, which areas have received some attention and which have not yet been addressed. Thus, this contribution will serve as both the basis and the starting point for new research into the field. PMID:27141725

  9. A Literature Review on Organizational Commitment – A Comprehensive Summary

    Directory of Open Access Journals (Sweden)

    Sayani Ghosh

    2014-12-01

    Full Text Available The paper encapsulates the evolution of the concept of organizational commitment, and its constructs. It focuses and analyses the literature findings of organizational commitments over the last five decades. It categorizes the approaches into six broad eras, each era being an extension and modification over the preceding ones. This review paper brings to the fore the theories that have emerged in the body of knowledge regarding commitment in organizations in a chronological order, starting from the side bet theory to the more recent multiple commitment approach. The gaps in the theories proposed have been identified and reviewed critically. It is difficult to conceptualize and measure organizational commitment as it encompasses a vast and highly diverse body of knowledge. Due to this it becomes difficult to interpret and conclude from the existing bodies of literature. The paper also highlights the importance of recognizing the individual/employee‟s perspective towards organizational commitment.

    Nash, C. A. [Savannah River Site (SRS), Aiken, SC (United States). Savannah River National Lab. (SRNL)

    2015-10-01

    A literature review of oxalate oxidation processes finds that manganese(II)-catalyzed nitric acid oxidation of oxalate in precipitate filtrate is a viable and well-documented process. The process has been operated on the large scale at Savannah River in the past, including oxidation of 20 tons of oxalic acid in F-Canyon. Research data under a variety of conditions show the process to be robust. This process is recommended for oxalate destruction in H-Canyon in the upcoming program to produce feed for the MOX facility. Prevention of plutonium oxalate precipitation in filtrate can be achieved by concentrated nitric acid/ferric nitrate sequestration of oxalate. Organic complexants do not appear practical to sequester plutonium. Testing is proposed to confirm the literature and calculation findings of this review at projected operating conditions for the upcoming campaign.

    Full Text Available Objective: Predicting who responds to placebo treatment – and under which circumstances – has been a question of interest and investigation for generations. However, the literature is disparate and inconclusive. This review aims to identify publications that provide high quality data on the topic of placebo response (PR prediction. Methods: To identify studies concerned with PR prediction, independent searches were performed in an expert database (for all symptom modalities and in PubMed (for pain only. Articles were selected when a they assessed putative predictors prior to placebo treatment and b an adequate control group was included when the association of predictors and PRs were analyzed. Results: Twenty-one studies were identified, most with pain as dependent variable. Most predictors of PRs were psychological constructs related to actions, expected outcomes and the emotional valence attached to these events (goal-seeking, self-efficacy/-esteem, locus of control, optimism. Other predictors involved behavioural control (desire for control, eating restraint, personality variables (fun seeking, sensation seeking, neuroticism, biological markers (sex, a single nucleotide polymorphism related to dopamine metabolism. Finally, suggestibility and beliefs in expectation biases, body consciousness and baseline symptom severity were found to be predictive. Conclusions: While results are heterogeneous, some congruence of predictors can be identified. PRs mainly appear to be moderated by expectations of how the symptom might change after treatment, or the expectation of how symptom repetition can be coped with. It is suggested to include the listed constructs in future research. Furthermore, a closer look at variables moderating symptom change in control groups seems warranted.

    Glovebox Stripper Systems (GBSS) are intended to minimize tritium emissions from glovebox confinement systems in Tritium facilities. A question was raised to determine if an assumed 99% stripping (decontamination) efficiency in the design of a GBBS was appropriate. A literature review showed the stated 99% tritium capture efficiency used for design of the GBSS is reasonable. Four scenarios were indicated for GBSSs. These include release with a single or dual stage setup which utilizes either single-pass or recirculation for stripping purposes. Examples of single-pass as well as recirculation stripper systems are presented and reviewed in this document.

    2015-09-01

    The aim of this article was to describe Descemet's membrane detachment (DMD) following phacoemulsification in five equine eyes and to review the human literature on this topic. In the last decade, there has been increased reporting of DMD in the human literature, in particular following cataract surgery. The natural history of DMD remains unknown and although various medical and surgical treatments have been advocated there is no recognized 'gold standard' treatment for DMD. This case series reports the diagnosis of DMD in four horses (5 eyes) in association with phacoemulsification surgery. The diagnosis of DMD in these patients was made intra-operatively, postoperatively or on subsequent histopathological examination. The surgical reports, photographic or video recordings, and ultrasound data were evaluated and possible factors associated with the pathophysiology of DMD are discussed. This is the first description of DMD in the veterinary literature, and the authors believe that DMD might hitherto have been overlooked in veterinary ophthalmology due to a lack of awareness of the condition. The possible causes, clinical signs, and treatment of DMD as described in the human literature are also reviewed. PMID:25180582
