  2. Re-Viewing Literature in Hermeneutic Research

    Directory of Open Access Journals (Sweden)

    Elizabeth Smythe PhD, RN, RM

    2012-02-01

    Full Text Available In academia there seems to be a taken for granted assumption that there is one way to do a literature review. This paper argues that the manner of reviewing literature needs to be congruent with the particular research methodology. As an example, the authors explicate reviewing literature in hermeneutic research. The paper begins by discussing philosophical assumptions. The authors then offer personal accounts of their experiences of working with literature in ways that are congruent with hermeneutic methodology. It is argued that the key purpose of exploring literature in hermeneutic research is to provide context and provoke thinking. Literature, which can include anything that provokes thinking on the phenomenon of interest, becomes an essential dialogical partner from which scholarly thinking and new insights emerge. In conclusion distinguishing hallmarks of ways of working hermeneutically with literature are articulated

The aligned eye was the right eye and keratoconus in this eye was of late onset. Vision in the left eye was poor and keratoconus was advanced in this eye. Due to the longstanding nature of the keratoconus and its occurrence in a developmentally sensitive period, sensory exotropia had developed in the left eye. There was a nodular lesion of the bulbar conjunctiva in the ipsilateral eye. If keratoconus occurs before the age of 7 years and the prolonged visual loss is not corrected, sensory strabismus can develop, as in this patient.Keywords: keratoconus, sensory exotropia, childhood

  5. Grounded theory research: literature reviewing and reflexivity.

    Science.gov (United States)

    McGhee, Gerry; Marland, Glenn R; Atkinson, Jacqueline

    2007-11-01

    This paper is a report of a discussion of the arguments surrounding the role of the initial literature review in grounded theory. Researchers new to grounded theory may find themselves confused about the literature review, something we ourselves experienced, pointing to the need for clarity about use of the literature in grounded theory to help guide others about to embark on similar research journeys. The arguments for and against the use of a substantial topic-related initial literature review in a grounded theory study are discussed, giving examples from our own studies. The use of theoretically sampled literature and the necessity for reflexivity are also discussed. Reflexivity is viewed as the explicit quest to limit researcher effects on the data by awareness of self, something seen as integral both to the process of data collection and the constant comparison method essential to grounded theory. A researcher who is close to the field may already be theoretically sensitized and familiar with the literature on the study topic. Use of literature or any other preknowledge should not prevent a grounded theory arising from the inductive-deductive interplay which is at the heart of this method. Reflexivity is needed to prevent prior knowledge distorting the researcher's perceptions of the data.

    Thakre, Subhash B; Thakre S, Sushama S; Thakre, Amol D

    2013-09-01

    Search for specific and well defined literature related to subject of interest is the foremost step in research. When we are familiar with topic or subject then we can frame appropriate research question. Appropriate research question is the basis for study objectives and hypothesis. The Internet provides a quick access to an overabundance of the medical literature, in the form of primary, secondary and tertiary literature. It is accessible through journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualised, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Scirus, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Several web-libraries (National library Medicine, Cochrane, Web of Science, Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature, levels of evidence, and detail about features of search engine as available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine. Literature search is a dynamic and interactive process; there is no one way to conduct a search and there are many variables involved. It is suggested that a systematic search of literature that uses available electronic resource effectively, is more likely to produce quality research.

    Science.gov (United States)

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    Full Text Available Candida norvegensis is an emerging fluconazole-resistant pathogen isolated in most cases from skin and mucous membranes of immunocompromized patients. Documented invasive candidiasis (IC due to C. norvegensis has been rarely reported, thus the clinical features of patients at risk for this pathogen are poorly defined. We report a liver transplant patient who developed IC due to C. norvegensis and review other cases of C. norvegensis IC published in the literature.

    Seth, Mayank; Lamberg, Eric

    2017-08-01

    Balance is an important variable to consider during the rehabilitation process of individuals with trans-tibial amputation. Limited evidence exists on the balance abilities of people with trans-tibial amputation due to vascular causes. The purpose of this article is to review literature and determine if standing balance is diminished in people with trans-tibial amputation due to vascular causes. Literature review. Data were obtained from PubMed, Google Scholar, OandP.org , CINHAL, and Science Direct. Studies were selected only if they included standing balance assessment of people with unilateral trans-tibial amputation due to vascular causes. The review yielded seven articles that met the inclusion criteria. The general test methodology required participants to stand still on force platforms, with feet together, while center of pressure or postural sway was recorded. According to the findings of this review, individuals with trans-tibial amputees due to vascular causes have diminished balance abilities. Limited evidence suggests their balance might be further diminished as compared to individuals with trans-tibial amputation due to trauma. Although the evidence is limited, because of the underlying pathology and presence of comorbidities in individuals with trans-tibial amputation due to vascular causes, one cannot ignore these findings, as even a minor injury from a fall may develop into a non-healing ulcer and affect their health and well-being more severely than individuals with trans-tibial amputation due to trauma. Clinical relevance Individuals with trans-tibial amputation due to vascular causes have diminished balance abilities compared to healthy individuals and individuals with trans-tibial amputation due to trauma. This difference should be considered when designing and fabricating prostheses. Prosthetists and rehabilitation clinicians should consider designing amputation cause-specific rehabilitation interventions, focussing on balance and other

  16. A Systematic Literature Review of Agile Maturity Model Research

    Directory of Open Access Journals (Sweden)

    Vaughan Henriques

    2017-02-01

    Full Text Available Background/Aim/Purpose: A commonly implemented software process improvement framework is the capability maturity model integrated (CMMI. Existing literature indicates higher levels of CMMI maturity could result in a loss of agility due to its organizational focus. To maintain agility, research has focussed attention on agile maturity models. The objective of this paper is to find the common research themes and conclusions in agile maturity model research. Methodology: This research adopts a systematic approach to agile maturity model research, using Google Scholar, Science Direct, and IEEE Xplore as sources. In total 531 articles were initially found matching the search criteria, which was filtered to 39 articles by applying specific exclusion criteria. Contribution:: The article highlights the trends in agile maturity model research, specifically bringing to light the lack of research providing validation of such models. Findings: Two major themes emerge, being the coexistence of agile and CMMI and the development of agile principle based maturity models. The research trend indicates an increase in agile maturity model articles, particularly in the latter half of the last decade, with concentrations of research coinciding with version updates of CMMI. While there is general consensus around higher CMMI maturity levels being incompatible with true agility, there is evidence of the two coexisting when agile is introduced into already highly matured environments. Future Research:\tFuture research direction for this topic should include how to attain higher levels of CMMI maturity using only agile methods, how governance is addressed in agile environments, and whether existing agile maturity models relate to improved project success.

    2013-09-01

    Full Text Available In times of crisis, companies need to carefully monitor current expenses and forecast potential costs, which could be caused by risky actions. Risk is inherent in all business functions and in every kind of activity. Knowing how to identify risks, attribute a value and a priority scale, design actions and mechanisms to minimize risks, and continuously monitor them, are essential to guarantee companies’ survival and create sustainable value. This is especially true for small- and medium-sized businesses that are most exposed to the harmful effects of the risks, due to limited resources and structural features. The objective of this study is to analyze available literature on the subject of risk management for small- and medium-sized enterprises from 1999 to 2009. The analysis derives interesting characteristics from the scientific studies, highlighting gaps and guidelines for future research.

    Full Text Available Context: Brucellosis is actually considered to be the commonest zoonotic infection worldwide; conversely prosthetic infection due to brucella is extremely rare. Although diagnostic is easily achieved, management of such situations is extremely challenging. Aims: To report the case of prosthetic hip loosening due to brucellar infection, discuss management manners and to summarize data about 19 cases reported in the literature. Methods: We report the case of a 73-year-old woman with brucellar prosthetic hip loosening treated with 2-stage exchange of the prosthesis and prolonged double antibiotherapy Results: At two years follow up the patient is pain free with total functional recovery and no clinical and radiographic signs of prosthetic loosening Conclusions: Brucella should be evocated as a cause of total joint arthroplasty infection especially in patients from endemic regions and with occupational exposure. Antibiotic treatment alone can be followed if there are no signs of implant loosening. Tow stage revision should be considered in other cases.

    2016-03-01

    This study reviewed grey literature to assess clinical nursing and midwifery research conducted in southern and eastern African countries over the past decade. The shortage of published nursing research from African countries severely limits the ability of practicing nurses and midwives to base clinical decisions on solid evidence. However, little is known regarding unpublished or unindexed clinical research ('grey literature'), a potentially rich source of information. Identifying these sources may reveal resources to assist nurses in providing evidence-based care. This scoping review of grey literature on clinical nursing and midwifery research in southern and eastern African countries helped to identify gaps in research and assess whether these gaps differ from published research. Systematic searches of grey literature were performed. Research was included if it was conducted by nurses in 1 of 25 southern or eastern African countries, between 2004 and 2014 and included patient outcomes. Data were extracted on location, institution, research topic, institutional connections and author information. Chi-square tests were performed to compare differences between indexed and non-indexed literature. We found 262 studies by 287 authors from 17 southern and eastern African countries covering 13 topics. Although all topics were also found in indexed literature and there were statistically significant differences between the number of times, fewer topics were covered in grey literature vs. indexed. Patient satisfaction and experience and traditional health practices were more likely to be published, whereas chronic disease, assault and paediatric-related research were less often published. Generally, there is a paucity of clinical nursing research in this region. This could reflect the shortage of nurses prepared to conduct research in this region. Nurses may find additional resources for evidence in the grey literature. A complete understanding of the state of nursing

    Francesco De Luca

    2016-07-01

    Full Text Available Malignant priapism secondary to penile metastases is a rare condition. This term was originally used by Peacock in 1938 to describe a condition of painful induration and erection of the penis due to metastatic infiltration by a neoplasm. In the current literature there are 512 case reports. The primary tumor sites are bladder, prostate and rectum. The treatment has only palliative intent and consists of local tumor excision, penectomy, radiotherapy and chemotherapy. We present one case of malignant priapism originated from prostate cancer, and two from urothelial carcinoma of the bladder. Different approaches in diagnosis and therapy were performed. The entire three patient reported a relief of the pain following the treatment, with an improvement of their quality of life, even though it was only temporary as a palliative. Malignant priapism is a rare medical emergency. Penile/pelvis magnetic resonance imaging (MRI scan and corporal biopsies are considered an effective method of diagnosis of the primary organ site.

    Full Text Available Reprocessing of both endoscopic instruments and reusable disposals is mandatory to prevent infection transmission. However, toxic colitis due to endoscope contamination by different disinfectants following an imperfect washing has been reported. We present a case of peracetic acid-induced colitis and reviewed the literature. Overall, five cases of peracetic acid toxic colitis have been reported. All cases presented with "snow white sign" immediately appearing during endoscopy, two patients complaint of mild abdominal pain (one of whom had also fever and rectal bleeding, whilst the others remained totally asymptomatic. Only one patient received a 1-week metronidazole treatment. No immediate complications were observed, and no sequels occurred at clinical-endoscopic follow-up. The identified cause of disinfectant contamination was a defective either manual or automated rinsing of the colonoscope following the reprocessing procedure.

    There have been a number of debates in the field of nursing ethics. Researchers have focused on various aspects of nursing ethics, such as professional ethics, professional, nursing and ethical values. Within this research, a variety of literature reviews have been conducted, but to the best of our knowledge, bibliometric mapping has not yet been used. This article aims to analyse the production of literature within nursing ethics research. In order to examine publishing patterns, we focused on publishing dynamics, prolific research entities and the most-cited articles. We additionally visualised the content of the literature using a novel mixed-method approach, combining bibliometric analysis and mapping with thematic analysis. Ethical considerations: In our study, ethical review was not required. A total of 1416 information sources were found in the Scopus database. Overall, literature production has increased; however, in recent years, the quantity of published material has begun to decrease. The most prolific countries are the United States, the United Kingdom and Canada, and the most prolific source titles are Nursing Ethics, Journal of Advanced Nursing and Nursing Times. Lately, research in the field of nursing ethics has been focused more on life care (providing for the basic needs of older residents), moral distress and community nursing. The dynamics of research literature production showed an exponential rise in the number of published information sources - a rise which started in the period between 1974 and 1998. Since that period, the trend has stabilised, which might indicate that nursing ethics research is starting a transition to a mature phase. The innovative use of bibliometric analysis and mapping, together with thematic analysis, is a useful tool for analysis of research production in the field of nursing ethics. The results presented can be an excellent starting point for literature reviews and more exhaustive data, information and knowledge

  3. Intestinal obstruction due to Vasconcellea seeds: Report of three cases and literature review

    Directory of Open Access Journals (Sweden)

    Montoya-González, Juliana

    2015-07-01

    Full Text Available Vasconcellea spp., is a species of Andean papaya commonly cultivated in rural communities close to Medellín, Colombia. Due to the pleasant and sweet flavor of its fruits, children frequently ingest its seeds accidentally. After ingestion, the seeds are engaged in the colonic lumen and block the exit of stools, causing pain and bloating, and promoting bacterial translocation. Diagnosis is based on clinical history and rectal examination. Treatment depends on the degree of local and systemic involvement and includes disimpaction of rectal contents under general anesthesia and colonic washes with 0.9% saline solution. In severe cases derivative colostomy has been required. In the literature there are no reports of intestinal obstruction due to Vasconcellea seeds, possibly because it has been mistaken for seeds of the genus Carica. In this article, three cases treated at pediatric services in Medellín, Colombia, in 2012 and 2013 are described. We note that this is a rarely suspected disease, leading to late diagnosis and potential catastrophic consequences. It is important to educate people to prevent the ingestion of the seeds.

    Dolan, Erin L

    2007-01-01

    The absence of a central database and use of specialized language hinder nonexperts in becoming familiar with the science teaching and learning literature and using it to inform their work. The challenge of locating articles related to a specific question or problem, coupled with the difficulty of comprehending findings based on a variety of different perspectives and practices, can be prohibitively difficult. As I have transitioned from bench to classroom-based research, I have become familiar with how to locate, decipher, and evaluate the education research literature. In this essay, I point out analogies to the literature of science research and practice, and I reference some of the literature that I have found useful in becoming an education researcher. I also introduce a new regular feature, "Current Insights: Recent Research in Science Teaching and Learning," which is designed to point CBE--Life Sciences Education (CBE-LSE) readers to current articles of interest in life sciences education, as well as more general and noteworthy publications in education research.

  12. A Literature Review of Shock Sensitivity Changes of TATB Due to Thermal Cycling

    Energy Technology Data Exchange (ETDEWEB)

    2016-07-15

    Insensitive high explosives (IHEs) based on 1,3,5-triamino 2,4,6-trinitro-benzene (TATB) are the IHEs of choice for use in nuclear warheads over conventional high explosives when safety is the only consideration, because they are very insensitive to thermal or mechanical initiation stimuli. It is this inherent insensitivity to high temperatures, shock, and impact, which provides detonation design challenges when designing TATB explosive systems while at the same time providing a significant level of protection against accidental initiation. Although classified as IHE, over the past few years the focus on explosive safety has demonstrated that the shock sensitivity of TATB is influenced with respect to temperature. A number of studies have been performed on TATB and TATB formulations, plastic bonded explosives (PBX) 9502, and LX-17-01 (LX-17), which demonstrates the increase in shock sensitivity of the explosive after it has been preheated or thermally cycled over various temperature ranges. Many studies suggest the change in sensitivity is partly due to the decomposition rates of the temperature elevated TATB. Others point to the coefficient of thermal expansion, the crystalline structures of TATB and/or the combination of all factors, which create voids which can become active hot spots. During thermal cycling, TATB is known to undergo an irreversible increase in specific volume called ratchet growth. This increase in specific volume correlates to a decrease in density. This decrease in density and increase in volume, demonstrate the creations of additional void spaces which could serve as potential new initiation hot spots thus, increasing the overall sensitivity of the HE. This literature review evaluates the published works to understand why the shock sensitivity of TATB-based plastic bonded explosives (PBXs) changes with temperature.

    Big data and cutting-edge analytic methods in nursing research challenge nurse scientists to extend the data sources and analytic methods used for discovering and translating knowledge. The purpose of this study was to identify, analyze, and synthesize exemplars of big data nursing research applied to practice and disseminated in key nursing informatics, general biomedical informatics, and nursing research journals. A literature review of studies published between 2009 and 2015. There were 650 journal articles identified in 17 key nursing informatics, general biomedical informatics, and nursing research journals in the Web of Science database. After screening for inclusion and exclusion criteria, 17 studies published in 18 articles were identified as big data nursing research applied to practice. Nurses clearly are beginning to conduct big data research applied to practice. These studies represent multiple data sources and settings. Although numerous analytic methods were used, the fundamental issue remains to define the types of analyses consistent with big data analytic methods. There are needs to increase the visibility of big data and data science research conducted by nurse scientists, further examine the use of state of the science in data analytics, and continue to expand the availability and use of a variety of scientific, governmental, and industry data resources. A major implication of this literature review is whether nursing faculty and preparation of future scientists (PhD programs) are prepared for big data and data science. Copyright © 2016 Elsevier Inc.

    2010-09-15

    In recent years, the gulf between the mass of accumulating-research data and the massive literature describing and analyzing those data has widened. The need for intelligent tools to bridge this gap, to rescue the knowledge being systematically isolated in literature and data silos, is now widely acknowledged. To this end, we have developed Utopia Documents, a novel PDF reader that semantically integrates visualization and data-analysis tools with published research articles. In a successful pilot with editors of the Biochemical Journal (BJ), the system has been used to transform static document features into objects that can be linked, annotated, visualized and analyzed interactively (http://www.biochemj.org/bj/424/3/). Utopia Documents is now used routinely by BJ editors to mark up article content prior to publication. Recent additions include integration of various text-mining and biodatabase plugins, demonstrating the system's ability to seamlessly integrate on-line content with PDF articles. http://getutopia.com.

  17. Using research literature to develop a perceptual retraining treatment protocol.

    Science.gov (United States)

    Neistadt, M E

    1994-01-01

    Treatment protocols derived from research literature can help therapists provide more rigorous treatment and more systematic assessment of client progress. This study applied research findings about the influence of task, subject, and feedback parameters on adult performance with block designs to an occupational therapy treatment protocol for parquetry block assembly--an activity occupational therapists use to remediate constructional deficits. Task parameter research suggests that parquetry tasks can be graded according to the features of the design cards, with cards having all block boundaries drawn in being easier than those with some block boundaries omitted. Subject parameter findings suggest that clients' lesions and initial constructional competence can influence their approaches to parquetry tasks. Feedback parameter research suggests that a combination of perceptual and planning cues is most effective for parquetry tasks. Methods to help clients transfer constructional skills from parquetry to functional tasks are also discussed.

  18. Mapping the organizational culture research in nursing: a literature review.

    Science.gov (United States)

    Scott-Findlay, Shannon; Estabrooks, Carole A

    2006-12-01

    This paper reports a critical review of nursing organizational culture research studies with the objectives of: (1) reviewing theoretical and methodological characteristics of the studies and (2) drawing inferences specific to the state of knowledge in this field. Organizational culture is regarded as significant in influencing research use in clinical practice yet it is not understood how culture shapes practitioners' behaviours. Only one review of this empirical literature in nursing has been completed. Using selected computerized databases, published nursing research studies in English that examine organizational culture were accessed. Organizational culture studies were categorized using Hatch's three perspectives on organizational culture: (1) modern, (2) symbolic-interpretive and (3) postmodern. The review was conducted in 2005. Twenty-nine studies were in the final data set. Results pointed to variations in cultural definitions and incorporation of organizational sciences theory. In classifying the studies, modern perspectives dominated (n = 22), symbolic-interpretive approaches were an emerging group (n = 6) and one study was unclassifiable. Our results expand current cultural instrument reviews by pinpointing tools that have been previously overlooked and by identifying ongoing theoretical and methodological challenges for researchers. An exclusive reliance on modernistic approaches in organizational culture research cannot yield a complete understanding of the phenomenon. Rather, the field could benefit from a variety of cultural approaches. In a similar vein, researchers need to be mindful of the terminology and the unit of analysis they use in their research, as these are the two largest research challenges.

    Davis, Jullet A; Savage, Grant; Stewart, R Thomas

    2003-01-01

    The use of downsizing as management's strategic response to environmental and institutional changes is prevalent in all U.S. industries, including healthcare. The popular and research literature is inundated with reports on companies undergoing various stages of restructuring, which often include one or more staff reductions. This article provides a review of downsizing literature published from 1985 to 2002. Although the findings and conclusions of these articles are generally inconsistent, the prevailing opinion is that for downsizing to be successful, effective planning must occur long before, during, and after downsizing. Additionally, a downsizing plan should be included in the strategic management plan of all organizations, regardless of whether they plan to downsize or not. By including such a plan, the organization will be better prepared to begin the staff-reduction process should it be forced to do so in response to environmental changes. Finally, providing ample support and protection for staff is key to the organization's recovery and growth. The lessons provided in this literature review should assist healthcare managers in deciding how to plan and structure potential staff reductions.

    To review the mycology, pathogenesis, clinical characteristics, investigations, and treatment modalities of mucormycosis. A local case of mucormycosis; MEDLINE and non-MEDLINE search of the literature. Key words for the literature search were 'mucormycosis' and 'Mucorales'; all available years of study were reviewed. Original articles, review papers, meta-analyses, and relevant book chapters were reviewed. Mucormycosis is a fungal infection that is rare but increasingly recognised in the growing population of immunocompromised patients. It is caused by saprophytic non-septate hyphae of the order Mucorales. The pulmonary and disseminated forms commonly occur in patients with haematological malignancy, especially acute leukaemia and lymphoma, and those receiving treatment with immunosuppressive effects. The rhinocerebral form is more prevalent in patients with diabetes mellitus, particularly those with the complication of diabetic ketoacidosis. The use of amphotericin B combined with surgery remains the mainstay of treatment. The prognosis largely depends on prompt correction of the underlying risk factors. New strategies to combat this life-threatening infection will result from better understanding of its pathogenesis. A high index of suspicion is needed, in appropriate clinical settings, to diagnose and aggressively treat this infection in view of the high mortality rate for susceptible patients.

    Infective endocarditis (IE) is a severe disease with high mortality and morbidity. Prosthetic valve endocarditis is a life-threatening complication which can occur in less than 10% of patients with valve prosthesis. A fungal etiology of IE is rare and accounts for only 2-4% of all case of endocarditis, but is associated with a higher mortality and morbidity. Herein is reported the first case of fungal endocarditis of aortic valve prosthesis due to Aspergillus oryzae in a 67-year-old caucasian man who nine years previously underwent mitral and aortic valve replacement with mechanical prostheses, and tricuspid annuloplasty for acute IE due to Enterococcus spp. Seven months previously, the patient also underwent a redo cardiac procedure to replace a mitral valve prosthesis with a new mechanical device due to a leakage. Aspergillus oryzae showed impressive growth with strong and unexpected virulence in both local and systemic settings.

    Full Text Available Abstract Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. We report a case of a woman who presented an ileocecal intussusception due to a cecal endometriosis. The patient gave two months history of chronic periombilical pain requiring regular hospital admission and analgesia. The symptoms were not related to menses. A laparotomy was performed and revealed an ileocolic intussusception. The abdominal exploration did not find any endometriosis lesion. Ileocaecal resection was performed. Microscopic examination showed a cystic component, lined by a regular cylindric epithelium. Foci of endometrial tissu were oberved in the cecal subserosa and muscularis mucosal, with irregular endometrial glands lined by cylindric epithelium without atypia immunostained with CK7, and characteristic endometrial stroma immunostained with CD10. Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. Diagnose of etiology remains challenging due to the absence of clinical and radiological specific characteristics.

    2001-04-01

    A literature survey has been carried out in support of ongoing source term calculations with the MELCOR code of some severe accident scenarios for the Swedish Ringhals 2 pressurised water reactor (PWR). The research in the field of severe accidents in power reactors and the source term for subsequent release of radioisotopes was intensified after the Harrisburg accident and has produced a large amount of reports and papers. This survey was therefore limited to research concerning PWR type of reactors and with emphasis on papers related to MELCOR code development. A background is given, relating to some historic documents, and then more recent research after 1990 is reviewed. Of special interest is the ongoing PMbus-programme which is creating new and important results of benefit to the code development and validation of, among others, the MELCOR code. It is concluded that source term calculations involve simulation of many interacting complex physical phenomena, which result in large uncertainties The research has, however, over the years led to considerable improvements Thus has the uncertainty in source term predictions been reduced one to two orders of magnitude from the simpler codes in the early 1980-s to the more realistic codes of today, like MELCOR.

  12. Critical factors for EIA implementation: literature review and research options.

    2013-01-15

    After decades of development, the gap between expectations of Environment Impact Assessments (EIA) and their practical performance remains significant. Research has been done to identify the critical factors for an effective implementation of EIA. However, this research, to a large extent, has not been cumulated and analysed comprehensively according to the stages of the EIA process. This paper contributes to the critical review of the literature on EIA implementation and effectiveness by cumulating mainly empirical findings in an implementation theoretical perspective. It focuses on the links between different critical factors and how they relate to different stages in the EIA and thus influence the decision making process. After reviewing 33 refereed journal articles published between 1999 and 2011, we identified 203 notions of critical factors. Of these, 102 related to different stages defined in our comprehensive EIA implementation model, and 101 were identified as general factors related to the whole EIA system. The number of notions of stage factors and general factors is thus about equal. An overlap between stage factors and general factors was found, which demonstrates that critical factors function differently in different cases. The function of the critical factors is complex and it is difficult to determine contingencies and causations. In the sources we examined, there is evidently an imbalance between in-depth empirical research and general knowledge, and the paper offers some suggestions for future research.

    Rubella virus infection during the first trimester of pregnancy can cause congenital rubella syndrome (CRS). We aimed to describe the abnormalities in order to define the ultrasound features to look for when performing prenatal scans. The goal of this review is to focus specifically on the signs of CRS accessible to prenatal diagnosis. We analyzed every case of CRS described before and/or after birth that we identified in the Pubmed database and classified them as accessible or not to prenatal diagnosis. The most frequently reported malformations accessible to prenatal diagnosis were: cardiac septal defects, pulmonary artery stenosis, microcephaly, cataract, microphtalmia, and hepatosplenomegaly. This extensive literature review shows that the ultrasound features of CRS are not well known, even though rubella was the first teratogenic virus described. This review will help clinicians in the management of rubella during pregnancy by clarifying the findings to be sought.

    We report a case of relapsing Haemophilus influenzae meningitis in a boy at the age of nearly 3 years and 4.2 years who had been successfully vaccinated against H. influenzae serotype b (Hib). The pathogen was a nonencapsulated (nontypable) H. influenzae strain of biotypes III and VI, respectively....... A rhinobasal impalement injury with development of a posttraumatic encephalocele is considered to be the predisposing condition. Review of the literature reveals that in patients systemically infected by nonencapsulated H. influenzae strains predisposing factors such as cerebrospinal fluid-shunts, implants...... and traumas are often found. To obtain further information on potential new disease patterns H. influenzae isolates from cerebrospinal fluid should be examined for capsule production and, if relevant, further characterized by capsular typing....

    Anaerobes used to be the most common cause of community-acquired lung abscess, and Streptococcus species used to be the second most common cause. In recent years, this has been changing. Klebsiella pneumoniae is now an increasing cause of community- acquired lung abscess, but Streptococcus species continue to be major pathogens. Necrotizing pneumonia has generally been regarded as a rare complication of pneumococcal infection in adults. Type 3 Streptococcus pneumoniae was the single most common type implicated in necrosis; however, many other serotypes were implicated. This entity predominately infects children, but is present also in adults. Lung abscess in adults due to Streptococcus pneumoniae is not common. In this regard we present a case series of pulmonary cavitation due to Streptococcus pneumoniae and discuss the possible pathogenic mechanism of the disease.

    Full Text Available Context: Prosthetic joint infection due to Mycobacterium tuberculosis with no previous history of pulmonary or extra pulmonary tuberculosis is an extremely rare complication. Aims To report the case of a patient with tuberculous mycobacterial prosthetic hip infection, 14 years after surgery for post traumatic osteoarthritis, with no previous history of tuberculosis. Methods A 46-year-old male presented an acetabular loosening of a cemented total hip arthroplasty with subnormal biologic parameters. A one stage revision surgery was planned. Intraoperative findings suggested mycobacterial tuberculous infection with presence of periacetabular yellowish rice-shaped granules. Results A one-stage prosthesis exchange was performed; Culture on Löwenstein-Jensen medium grew MTB days after inoculation and histological examination confirmed tuberculous infection. Patient was treated by antituberculous agents for 12 months with optimal clinical and biological response and no prosthetic loosening signs at eighteen months follow up. Conclusions Total hip arthroplasty loosening due to mycobacterium tuberculosis is a rare entity, which should be evoked even when no inflammatory signs are shown. Discovery of yellowish rice-shaped granules is an indicator to investigate for tuberculosis. Management of prosthetic joint infection due to M.tuberculosis must involve both medical and surgical approach.

  1. Renal failure due to primary amyloidosis: a case report and literature review

    Directory of Open Access Journals (Sweden)

    Ramon Andrade Bezerra de Mello

    Full Text Available CONTEXT: Primary amyloidosis, also known as AL amyloidosis, is commonly caused by clonal expansion of plasma cells in the bone marrow, thereby segregating light chains of clonal immunoglobulin that settle in tissues in the form of insoluble amyloid fibrils. The aim of this study was to report a case of primary amyloidosis with renal failure, diagnosed in Hospital São João, Porto, Portugal, focusing on the diagnostic difficulties and presenting a literature review. CASE REPORT: A 68-year-old Caucasian man was admitted to the Internal Medicine Department of the hospital with a condition of anasarca and nephrotic syndrome. After performing a renal biopsy that tested positive using Congo red and immunohistochemistry, lambda light chain amyloidosis was diagnosed. This evolved into terminal renal disease, which led to hemodialysis and several episodes of urinary and catheter infections. He was started on chemotherapy, consisting of bortezomib 0.7 mg/m² and dexamethasone 40 mg in six cycles. This led to clinical improvement, stabilization of the illness and good tolerance of the treatment. CONCLUSION: Amyloidosis is a rare entity that is difficult to diagnose. This is because of the unspecific early clinical manifestations of the disease. The hypothesis of amyloidosis is only considered when specific organ failure occurs. This case consisted of primary amyloidosis with involvement of the kidneys as an initial presentation of the disease and its difficulties were shown, going from the clinical approach to the final diagnosis.

    Laparoscopic adjustable gastric banding (LAGB) is a commonly performed bariatric procedure. Device-related morbidity is typically associated with the subcutaneous port or the band itself. Complications related to band tubing are unusual. Small bowel obstruction (SBO) after LAGB is a unique and serious complication; there is the potential of delayed diagnosis and the risk of closed-loop bowel obstruction. SBO secondary to internal hernia caused by band tubing is very rare, with only five cases reported in the literature. In this article, we describe our experience and provide an illustrative video of a case of SBO related to band tubing. We also provide a detailed review of the few previously published case reports. Based on the common features of our case and other published case reports, we hypothesize some risk factors that might lead to this unique morbidity of adjustable gastric band tubing and provide potential solutions to prevent this problem. Tubing-related SBO is a serious complication with the risk of closed-loop bowel obstruction. Urgent operative exploration is required to avoid bowel strangulation. To prevent recurrence we advise functionally shortening the tubing by tucking it to the right upper quadrant above the liver and also provide some omental coverage between the bowel and band tubing if possible.

    Full Text Available Dysmetropsia (macropsia, micropsia, teleopsia, or pelopsia most commonly results from retinal pathologies, epileptic seizure, neoplastic lesions, viral infection, or psychoactive drugs. Vascular lesions are an uncommon cause of dysmetropsia. Vascular hemimicropsia, although rare, has been more frequently described in the literature, whereas hemimacropsia from acute ischemic injury is exceedingly rare. We describe a patient presenting in the emergency room (ER with visual perception disturbances characterized by a distorted perception of the size of objects, compatible with left hemimacropsia. Magnetic resonance imaging (MRI of the brain showed an acute occipitotemporal ischemic injury corresponding to the posterior cerebral artery (PCA territory. The location of the lesion is consistent with previous case reports that suggest that hemimacropsia is associated with the occipitotemporal projection, which plays a decisive role in the visual identification of objects by interconnecting the striate, prestriate, and inferior temporal areas. The difference of our case as compared to previous case reports is that the lesion in our patient spared Brodmann area 17 (calcarine cortex and therefore did not present symptoms of quadrantanopsia. Instead, the patient presented isolated hemimacropsia, therefore suggesting that the anatomical lesion causing hemimacropsia is located in the ventral portion of the occipitotemporal projection, more specifically Brodmann areas 18 (parastriate and 19 (peristriate.

    Biotin (vitamin B7) is an essential co-factor for four carboxylases involved in fatty acid metabolism, leucine degradation, and gluconeogenesis. The recommended daily intake (RDI) of biotin is approximately 30 μg per day. Low-moderate dose biotin is a common component of multivitamin preparations, and high-dose biotin (10 000 times RDI) has been reported to improve clinical outcomes and quality of life in patients with progressive multiple sclerosis. Biotin is also a component of immunoassays, and supplementation may cause interference in both thyroid and non-thyroid immunoassays. To assess whether biotin ingestion caused abnormal thyroid function tests (TFTs) in a patient through assay interference. We report a patient with biotin-associated abnormal TFTs and a systematic review of the literature. A tertiary endocrine service in Hamilton, New Zealand. The patient had markedly abnormal TFTs that did not match the clinical context. After biotin cessation, TFTs normalized far more rapidly than possible given the half-life of T4, consistent with assay interference by biotin. Multiple other analytes also tested abnormal in the presence of biotin. Biotin ingested in moderate to high doses can cause immunoassay interference. Depending on the assay format, biotin interference can result in either falsely high or low values. Interference is not limited to thyroid tests and has the potential to affect a wide range of analytes. It is important for clinicians to be aware of this interaction to prevent misdiagnosis and inappropriate treatment.

    This report describes the case of a 42-year-old woman who consulted with a maxillofacial specialist for pain and an exophytic lesion in the maxilla. Biopsy examination disclosed a bone cyst with abundant giant cells, and head and neck computed tomography was performed. A diagnosis of brown tumor in the maxilla and mandible was made, and primary hyperparathyroidism (parathyroid adenoma) was determined as the origin of the bone lesions. The patient underwent a left superior parathyroidectomy, which resolved the hormonal disorder (as determined by normal calcium and parathyroid hormone levels) and the brown tumors, which appeared to have mineralized at 1-year follow-up computed tomography. Dental implant rehabilitation was performed at the sites of the absent tumors. A systematic review of articles published in the English-language medical literature through the PubMed and Medline databases yielded 40 articles (published from 1969 through 2016) on 45 cases of hyperparathyroidism associated with the location of a brown tumor in the mandible or maxilla.

    Salmonella paratyphi A causes paratyphoid fever which is characterized by acute onset of fever, abdominal pain, diarrhoea, nausea and vomiting. Localized disease can occur following both overt and silent bacteremia followed by seeding of bacteria at distant sites. Salmonella species though associated with abscess formation in various organs,are rarely associated with breast abscess. We report 2 cases of breast abscess due to Salmonella enterica serotype paratyphi A. Appropriate sampling, surgery supplemented by a comprehensive microbiological work up aided in pathogen identification and appropriate antibiotic administration for a successful outcome of these patients.

    To analyze the characteristics of hepatotoxicity due to ticlopidine. We describe all the case of hepatotoxicity attributed to ticlopidine and reported to the Register of drug associated hepatopathies. We also obtained data from MEDLINE and the Spanish Medical Index regarding cases reported during the period 1982 2001. We reported twelve cases of hepatopathy related to the use of ticlopidine. These made up 5% of all the cases notified to the Register. Eighty three percent of the patients were male, and of an average age of 68 years. Sixty six percent required hospital admission. The latent period varied between 2 and 13 weeks. The liver lesion was of cholestatic type in 75% of the cases, hepatocellular in 16.6% and mixed in 8.3%. Twenty five percent of the patients had received sub therapeutic doses. Ticlopidine is often related to hepatotoxicity. This seems to be due to an idiosyncratic mechanism and is mainly cholestatic. The use of lower dosage than that recommended means that the desired therapeutic effect is not attained but does not protect against the development of hepatotoxicity. Doctors who use this drug should be aware of this so as to establish the true risk benefit relation.

  11. Stridor and respiratory failure due to tracheobronchomalacia: case report and review of the literature

    Directory of Open Access Journals (Sweden)

    Ramon Andrade de Mello

    Full Text Available CONTEXT: Tracheobronchomalacia (TBM results from structural and functional abnormalities of the respiratory system. It is characterized by excessive collapse: at least 50% of the cross-sectional area of the trachea and main bronchi. In this paper, we present a rare case of a patient with TBM who first presented with stridor and respiratory failure due to exacerbation of chronic bronchitis. CASE REPORT: An 81-year-old Caucasian man was admitted presenting coughing, purulent sputum, stridor and respiratory failure. He had a medical history of chronic obstructive pulmonary disease (COPD and silicosis and was a former smoker. Axial computed tomography on the chest revealed marked collapse of the trachea in its middle third. Bronchoscopy showed characteristics compatible with TBM. He was treated with noninvasive ventilation, without any good response. Subsequently, a Dumon Y stent was placed by means of rigid bronchoscopy. After the procedure, he was discharged with a clinical improvement. CONCLUSION: TBM is fatal and often underdiagnosed. In COPD patients, stridor and respiratory failure may be helpful signs that should alert physicians to consider TBM as an early diagnosis. Thus, these signs may be important for optimizing the treatment and evolution of such patients.

  12. Lumbar Ureteral Stenosis due to Endometriosis: Our Experience and Review of the Literature

    Full Text Available Endometriosis is a chronic gynaecological disorder characterized by the presence of endometrial tissue outside the uterus. The disease most often affects the ovaries, uterine ligaments, fallopian tubes, and cervical-vaginal region. Urinary tract involvement is rare, accounting for around 1%-2% of all cases, of which 84% are in the bladder. We report a case of isolated lumbar ureteral stenosis due to endometriosis in a 37-year-old patient. The patient came to our observation complaining from lumbar back pain and presented with severe fever. The urological examination found monolateral left positive sign of Giordano. Blood tests evidenced marked lymphocytosis and increased valued of C-reactive protein. Urologic ultrasound showed hydronephrosis of first degree in the left kidney and absence of images related to stones bilaterally. Uro-CT scan evidenced ureteral stenosis at the transition between the iliac and pelvic tracts. We addressed the patient to surgery, and performed laparoscopic excision of the paraureteral bulk, endoscopic mechanical ureteral dilation, and stenting. The histological examination evidenced glandular structures lined by simple epithelium and surrounded by stroma. Immunohistochemical test of the glandular epithelium showed positivity for estrogen and progesterone receptors and moreover stromal cells were positive for CD10. The finding suggested a very rare diagnosis of isolated lumbar ureteral endometriosis.

    2016-01-01

    Full Text Available Malaria is endemic in large parts of India and can cause multiorgan failure and death. Acute pancreatitis as a complication is rare and is potentially fatal. This case series describes five adult patients between 2005 and 2010 who presented with a short duration febrile illness and diagnosed to have malaria with acute pancreatitis. The mean age of the five patients with acute pancreatitis was 40.4 years and four of them were males. None of them were alcohol consumers and did not have any other risk factor for acute pancreatitis. Plasmodium falciparum was responsible for all the cases. Pancreatic enzymes were significantly elevated in all the patients with a mean serum lipase level of 1795 U/L (normal value: 1.4 mg/dl, and hyperbilirubinemia were seen in all the patients. One patient died due to multiorgan failure. Acute pancreatitis is a very rare complication of malaria, and a high index of suspicion is required in patients presenting with severe malaria and abdominal pain.

  14. Sleep disturbance due to noise: Current issues and future research

    2010-01-01

    Full Text Available There is growing interest in carrying out further research to understand and reduce the impact of aircraft noise on airport neighborhood in anticipation of the projected substantial increase in global aviation. Soundscapes provide new analytical methods and a broader, more comprehensive appreciation of the aural environment, which may have a useful role in understanding noise-induced sleep disturbance and annoyance. Current noise metrics like Leq do not provide a common language to report noise environment to residents, which is a key obstacle to effective noise management and acceptance. Non-auditory effects complicate the production of consistent dose-response functions for aircraft noise affecting sleep and annoyance. There are various end-points that can be chosen to assess the degree of sleep disturbance, which has detracted from the clarity of results that has been communicated to wider audiences. The World Health Organization (WHO-Europe has produced Night Noise Guidelines for Europe, which act as a clear guide for airports and planners to work towards. Methodological inadequacies and the need for simpler techniques to record sleep will be considered with the exciting potential to greatly increase cost-effective field data acquisition, which is needed for large scale epidemiological studies

    2018-06-01

    A key outcome measure of cancer research training programs is the number of cancer-related peer-reviewed publications after training. Because program graduates do not routinely report their publications, staff must periodically conduct electronic literature searches on each graduate. The purpose of this study is to compare findings of an innovative computer-based automated search program versus repeated manual literature searches to identify post-training peer-reviewed publications. In late 2014, manual searches for publications by former R25 students identified 232 cancer-related articles published by 112 of 543 program graduates. In 2016, a research assistant was instructed in performing Scopus literature searches for comparison with individual PubMed searches on our 543 program graduates. Through 2014, Scopus found 304 cancer publications, 220 of that had been retrieved manually plus an additional 84 papers. However, Scopus missed 12 publications found manually. Together, both methods found 316 publications. The automated method found 96.2 % of the 316 publications while individual searches found only 73.4 %. An automated search method such as using the Scopus database is a key tool for conducting comprehensive literature searches, but it must be supplemented with periodic manual searches to find the initial publications of program graduates. A time-saving feature of Scopus is the periodic automatic alerts of new publications. Although a training period is needed and initial costs can be high, an automated search method is worthwhile due to its high sensitivity and efficiency in the long term.

    2013-01-01

    CONTEXT Coagulase-negative staphylococci are common colonizers of the human skin and have become increasingly recognized as agents of clinically significant nosocomial infections. CASE REPORT The case of a 79-year-old male patient with multi-infarct dementia who presented systemic inflammatory response syndrome is reported. This was attributed to bacteremia due to Staphylococcus cohnii ssp. urealyticus, which was grown on blood cultures originating from an infected pressure ulcer. The few cases of Staphylococcus cohnii infection reported in the literature consist of bacteremia relating to catheters, surgical prostheses, acute cholecystitis, brain abscess, endocarditis, pneumonia, urinary tract infection and septic arthritis, generally presenting a multiresistant profile, with nearly 90% resistance to methicillin. CONCLUSIONS The reported case is, to our knowledge, the first case of true bacteremia due to Staphylococcus cohnii subsp. urealyticus caused by an infected pressure ulcer. It shows that this species may be underdiagnosed and should be considered in the differential diagnosis for community-acquired skin infections.

    2015-01-01

    Resilience engineering (RE) has been advocated as a new safety management paradigm, compatible with the nature of complex socio-technical systems. This study aims to identify the research areas and to propose a research agenda for RE, based on a systematic literature review that encompasses 237 studies from 2006 to 2014. Six research areas are identified: theory of RE; identification and classification of resilience; safety management tools; analysis of accidents; risk assessment; and training. The area “theory of RE” accounted for 52% of the studies, and it indicates that research has emphasized the description of how resilient performance occurs. The proposal for a research agenda is focused on: refining key constructs; positioning RE in relation to other theories; exploring other research strategies in addition to case-based studies; investigating barriers for implementing RE; and balancing the importance on describing and understanding resilience with the emphasis on the design of resilient systems, and the evaluation of these designs. - Highlights: • Six research areas on RE are identified. • A research agenda for RE is proposed. • RE research is mostly descriptive and based on case studies. • Design science is suggested as a research strategy for RE. • Five domains account for 75% of the reviewed studies

  4. Severe Hypoglycemia due to Isolated ACTH Deficiency in Children: A New Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Michael Y. Torchinsky

    2011-01-01

    Full Text Available Isolated ACTH deficiency causes life-threatening severe hypoglycemia. A 7-year-old girl with hypoglycemia due to this rare disorder is described. Our patient had undetectable plasma ACTH repeatedly and cortisol 0 mcg/dl before and after ACTH 1-24 stimulation. There was no evidence of other pituitary hormone deficiency. Glucocorticoid replacement therapy resulted in resolution of all symptoms and normalization of blood glucose. Previously published data on isolated ACTH deficiency in children is summarized. Review of the literature showed that the prevalence of this condition could be underestimated in the neonatal period and in Prader-Willi syndrome. Isolated ACTH deficiency occurs in older children as well as in neonates.

    Identifying research gaps is a fundamental goal of literature reviewing. While it is widely acknowledged that literature reviews should identify research gaps, there are no methodological guidelines for how to identify research gaps in qualitative literature reviews ensuring rigor and replicability....... Our study addresses this gap and proposes a framework that should help scholars in this endeavor without stifling creativity. To develop the framework we thoroughly analyze the state-of-the-art procedure of identifying research gaps in 40 recent literature reviews using a grounded theory approach....... Based on the data, we subsequently derive a framework for identifying research gaps in qualitative literature reviews and demonstrate its application with an example. Our results provide a modus operandi for identifying research gaps, thus enabling scholars to conduct literature reviews more rigorously...

    Jonathan Soldera

    Full Text Available CONTEXTCoagulase-negative staphylococci are common colonizers of the human skin and have become increasingly recognized as agents of clinically significant nosocomial infections.CASE REPORTThe case of a 79-year-old male patient with multi-infarct dementia who presented systemic inflammatory response syndrome is reported. This was attributed to bacteremia due to Staphylococcus cohnii ssp. urealyticus, which was grown on blood cultures originating from an infected pressure ulcer. The few cases of Staphylococcus cohnii infection reported in the literature consist of bacteremia relating to catheters, surgical prostheses, acute cholecystitis, brain abscess, endocarditis, pneumonia, urinary tract infection and septic arthritis, generally presenting a multiresistant profile, with nearly 90% resistance to methicillin.CONCLUSIONSThe reported case is, to our knowledge, the first case of true bacteremia due to Staphylococcus cohnii subsp. urealyticus caused by an infected pressure ulcer. It shows that this species may be underdiagnosed and should be considered in the differential diagnosis for community-acquired skin infections.

  15. Characteristics of a productive research environment: literature review.

    Science.gov (United States)

    Bland, C J; Ruffin, M T

    1992-06-01

    What environmental factors stimulate and maintain research productivity? To answer this question, the authors conducted an extensive review of articles and books on research productivity published from the mid-1960s through 1990. This review revealed that a consistent set of 12 characteristics was found in research-conducive environments: (1) clear goals that serve a coordinating function, (2) research emphasis, (3) distinctive culture, (4) positive group climate, (5) assertive participative governance, (6) decentralized organization, (7) frequent communication, (8) accessible resources, particularly human, (9) sufficient size, age, and diversity of the research group, (10) appropriate rewards, (11) concentration on recruitment and selection, and (12) leadership with research expertise and skill in both initiating appropriate organizational structure and using participatory management practices. Some of these characteristics are not surprising, although some findings were unexpected, such as that participative governance correlated consistently with research productivity. The differential impact of each of these 12 characteristics is unclear. It is clear, however, that the leader has a disproportionate impact through his or her influence on all of the other characteristics. Yet, an overarching feature of these characteristics is their interdependency. These factors do not operate in research groups as isolated characteristics. Rather, they are like fine threads of a whole fabric: individual, yet when interwoven, providing a strong, supportive, and stimulating backdrop for the researcher. The authors conclude that while at a distance the productive research enterprise looks like a highly robust entity, upon closer inspection it is revealed to be a delicate structure highly dependent on the existence and effective working of numerous individual, organizational, and leadership characteristics.

    Full Text Available Sustainability has become an increasingly popular topic in administration research projects, with a great number of researchers trying to understand and apply it to the corporate world. The general objective of the present study consists of investigating the theoretical perspectives of scientific production on sustainability in administration present in the annals of the Anpad Meeting and in the “Revista de Gestão Social e Ambiental”, over an eight-year period. The research encompasses the characteristics of authorship, methodological procedures and theoretical groundwork, as well as the qualitative characteristics of the selected articles. It is a qualitative study, characterized as descriptive research, with the application of bibliometrics and content analysis. 103 articles, published in the Anpad Meeting (annual editions, from 2003 to 2010 and in the “Revista de Gestão Social e Ambiental” (published three times a year, from 2007 to 2010, were analyzed. The results revealed an increase in scientific production on sustainability, demonstrating this topic’s growing maturity. In a more punctual way, researchers identified a tendency towards co-authorship; methodological diversity, not limited to theories or pre-defined models; and a high incidence of proposals of models related to sustainability.

  20. Reviewing Literature in Bioethics Research: Increasing Rigour in Non-Systematic Reviews.

    Science.gov (United States)

    McDougall, Rosalind

    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. © 2015 John Wiley & Sons Ltd.

  7. Eastern European Political Socialization Modeling Research: A Literature Review

    Directory of Open Access Journals (Sweden)

    Camelia Florela Voinea

    2014-01-01

    Full Text Available This paper presents empirical modeling research on political socialization of the citizens in the new Eastern European democracies. The political socialization issue offers a comparative perspective over the modeling methodologies in analytical paradigms. Eastern European political culture research has revealed features of the electoral behavior and political participation which can be identified in different degrees in all the new democracies in the area: passivity with respect to political activity of parties, elites and institutions, political apathy or lack of reaction to anti-democratic actions, skepticism or distrust in institutions, scarce participation to social movements. Several authors explain the actual political behavior of the Eastern European citizens’ and their low social and political involvement by the (political culture heritage of the communist regimes in which they lived for a long time, and which keeps shaping their political attitudes towards the state, civil society, government and institutions. Research issues in the analysis of political participation are traditionally based on statistics analyses of empirical evidence coming from public surveys. However, scarcity ofempirical data from the communist periode with regard to (political socialization, values and beliefs represent a major obstacle towards a better understanding of the historical roots of current behaviors and attitudes. Scarcity of observational data might be overcome by computational and simulation modeling.

  8. Communication about scientific uncertainty in environmental nanoparticle research - a comparison of scientific literature and mass media

    Heidmann, Ilona; Milde, Jutta

    2014-05-01

    The research about the fate and behavior of engineered nanoparticles in the environment is despite its wide applications still in the early stages. 'There is a high level of scientific uncertainty in nanoparticle research' is often stated in the scientific community. Knowledge about these uncertainties might be of interest to other scientists, experts and laymen. But how could these uncertainties be characterized and are they communicated within the scientific literature and the mass media? To answer these questions, the current state of scientific knowledge about scientific uncertainty through the example of environmental nanoparticle research was characterized and the communication of these uncertainties within the scientific literature is compared with its media coverage in the field of nanotechnologies. The scientific uncertainty within the field of environmental fate of nanoparticles is by method uncertainties and a general lack of data concerning the fate and effects of nanoparticles and their mechanisms in the environment, and by the uncertain transferability of results to the environmental system. In the scientific literature, scientific uncertainties, their sources, and consequences are mentioned with different foci and to a different extent. As expected, the authors in research papers focus on the certainty of specific results within their specific research question, whereas in review papers, the uncertainties due to a general lack of data are emphasized and the sources and consequences are discussed in a broader environmental context. In the mass media, nanotechnology is often framed as rather certain and positive aspects and benefits are emphasized. Although reporting about a new technology, only in one-third of the reports scientific uncertainties are mentioned. Scientific uncertainties are most often mentioned together with risk and they arise primarily from unknown harmful effects to human health. Environmental issues itself are seldom mentioned

  11. [Possible changes in energy-minimizer mechanisms of locomotion due to chronic low back pain - a literature review].

    de Carvalho, Alberito Rodrigo; Andrade, Alexandro; Peyré-Tartaruga, Leonardo Alexandre

    2015-01-01

    One goal of the locomotion is to move the body in the space at the most economical way possible. However, little is known about the mechanical and energetic aspects of locomotion that are affected by low back pain. And in case of occurring some damage, little is known about how the mechanical and energetic characteristics of the locomotion are manifested in functional activities, especially with respect to the energy-minimizer mechanisms during locomotion. This study aimed: a) to describe the main energy-minimizer mechanisms of locomotion; b) to check if there are signs of damage on the mechanical and energetic characteristics of the locomotion due to chronic low back pain (CLBP) which may endanger the energy-minimizer mechanisms. This study is characterized as a narrative literature review. The main theory that explains the minimization of energy expenditure during the locomotion is the inverted pendulum mechanism, by which the energy-minimizer mechanism converts kinetic energy into potential energy of the center of mass and vice-versa during the step. This mechanism is strongly influenced by spatio-temporal gait (locomotion) parameters such as step length and preferred walking speed, which, in turn, may be severely altered in patients with chronic low back pain. However, much remains to be understood about the effects of chronic low back pain on the individual's ability to practice an economic locomotion, because functional impairment may compromise the mechanical and energetic characteristics of this type of gait, making it more costly. Thus, there are indications that such changes may compromise the functional energy-minimizer mechanisms. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

    The Behavioral Health and Performance (BHP) Element is one of the six elements within the NASA Human Research Program (HRP) and is responsible for managing four risks: a) The Risk of Performance Decrements due to inadequate Cooperation, Coordination, Communication and Psychological Adaptation within a Team (Team), b) the Risk of Performance Errors due to Sleep Loss, Circadian De-synchronization, Fatigue and Work Overload (Sleep), c) Risk of Behavioral Conditions (BMed), and d) the Risk of Psychiatric Disorders (BMed). The aim of this report is to address some of the recommendations made by the recent NASA HRP Standing Review Panel for the Behavioral Medicine Risk of Psychiatric Disorders. Such recommendations included: a) the inclusion of important national and international literature in English and non-English language materials; including journals, books, magazines, conference reports and b) an extensive literature review of certain types of psychological states to predict, detect, and assess adverse mental states that may negatively affect the psychological well being of the astronauts, specifically asthenia. This report was a collaborative international work effort focused on the evaluation and determination of the importance of continuing research on asthenia as a possible psychological problem that might affect the optimal psychological functioning among crewmembers during long-duration space flight missions. Russian medical personnel (flight surgeons and psychologist) have observed symptoms of asthenia (weakness, increased fatigue, irritability, and attention and memory disorders) in cosmonauts after four months in space (Myasnikov& Zamaleddinov1996; Grigorieve, 1996 ) and believe that asthenia is one of the greater risks that will affect crews? optimal psychological functioning.

Following on from this programme, a compilation of the results produced, drawing also from a literature review, has been undertaken and is presented here. This scientific work, written by the research partners of the programme, draws from both their expertise and gained experience. It can thus be considered a 'state of the art' of the current understanding of atmospheric emissions from composting: be it emission values, means of measurement or of their control. The document is organized in three main parts: In the first, the general principles of composting and the related atmospheric emissions are given. The section also sets out the current understanding of the main impacts on the environment and on the health of staff and people living near the composting sites. The second part is deals with the quantification of the emissions. It describes the methods and strategies of sampling and analysis for gas emissions (including odors) and for particulates (including micro-organisms). The quantitative emission data provided in this section are current figures taken from reference documents already produced by ADEME. These values are brought up to date with data taken from international scientific literature and from the results of the research programme on the emissions from composting. The current report takes note in particular of the knowledge of factors affecting emission. The section then sets out the dispersion of the gaseous emissions and particulates around the site. It brings in modelling and the concept of background noise, essential in the interpretation of the results from measurement campaigns of the environment around compost sites. The third part looks at the consequences of the work given in the report. This includes especially recommendations for the prevention of emissions and for the direction of future studies. The outlook for future and related research is

    2016-11-25

    The delivery of radiotherapy (RT) involves the use of rather expensive resources and multi-disciplinary staff. As the number of cancer patients receiving RT increases, timely delivery becomes increasingly difficult due to the complexities related to, among others, variable patient inflow, complex patient routing, and the joint planning of multiple resources. Operations research (OR) methods have been successfully applied to solve many logistics problems through the development of advanced analytical models for improved decision making. This paper presents the state of the art in the application of OR methods for logistics optimization in RT, at various managerial levels. A literature search was performed in six databases covering several disciplines, from the medical to the technical field. Papers included in the review were published in peer-reviewed journals from 2000 to 2015. Data extraction includes the subject of research, the OR methods used in the study, the extent of implementation according to a six-stage model and the (potential) impact of the results in practice. From the 33 papers included in the review, 18 addressed problems related to patient scheduling (of which 12 focus on scheduling patients on linear accelerators), 8 focus on strategic decision making, 5 on resource capacity planning, and 2 on patient prioritization. Although calculating promising results, none of the papers reported a full implementation of the model with at least a thorough pre-post performance evaluation, indicating that, apart from possible reporting bias, implementation rates of OR models in RT are probably low. The literature on OR applications in RT covers a wide range of approaches from strategic capacity management to operational scheduling levels, and shows that considerable benefits in terms of both waiting times and resource utilization are likely to be achieved. Various fields can be further developed, for instance optimizing the coordination between the available

    The Behavioral Health and Performance Element (BHP) is one of the 6 elements in the NASA Human Research Program (HRP) and is responsible for managing 4 of the identified and named risks to human health and performance from human space exploration: a) Risk of Behavioral Conditions (BMed), b) Risk of Psychiatric Disorders (BMed), c) Risk of Performance Decrements due to inadequate Cooperation, Coordination, Communication and Psychological Adaptation within a Team (Team), and d) Risk of Performance Errors due to Sleep Loss, Circadian De-synchronization, Fatigue and Work Overload (Sleep). Each risk is reviewed by a NASA HRP Standing Review Panel (SRP), and recently the Behavioral Medicine Risk of Psychiatric Disorders was reviewed. The aim of this report is to address one of the recommendations made by that panel, specifically the recommendation that the "literature on asthenia should be evaluated (possibly as a psychological or psychosomatic / psycho-physiological analogue of chronic fatigue syndrome)" (SRP p. 4), in addition to General Recommendation 4, which states that "all reviews must include non-English language materials as well as materials appearing in conferences reports, books, and other non-refereed journal outlets" (SRP p. 2).

  6. Physical activity of pregnant women in the light of scientific research - a review of the literature

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Introduction: Physical activity during pregnancy is very important due to health benefits for women and fetus. Undoubtedly, physical activity should be adapted to the current psychophysical abilities of pregnant women. During that time, the physical effort should be taken by appropriate intensity, also the forms of physical activity should be general aimed in current pregnancy state. Undoubtedly the simplest form of physical activity for pregnant women is walk, as well as swimming, gymnastics, yoga and pilates. Exercises should have wide impact on her body and muscles. The aim of the study is to identify the physical activity of pregnant women in available scientific publications. Further goal is the assessment of the knowledge about the physical activity of pregnant women based on the current review of the literature. Research Methods: The following databases and scientific browsers were used and tracked for the purpose of the research objective: Pub Med, Retina Medical Search, Medline Plus, Europe PMC, POPLINE, Google Scholar. During searching for a results the keywords phrases were written in English: physical activity in pregnancy, pregnancy exercises, fitness, yoga, pilates, swimming and pelvic floor exercises during pregnancy. Conclusions: The current researches among the population of pregnant women are methodologically differentiated and not coherent in the subject. The implication of unexplored issues about pregnant women is the differentiation in directions of researches about the physical activity of pregnant women. It seems that is important to design and program an prospective research by using objective techniques to explore the pregnant women’s behavior, lifestyle and physical activity.

    The amount of published literature can be overwhelming for scientists and researchers moving from a broad disciplinary research area to a more specialized one, particularly in fields that use information from more than one discipline. Without a focused inquiry, the researcher may find too little information or may be overcome by too much. Striking the correct balance of information is the focus of Literature Search Strategies for Interdisciplinary Research. This useful reference tool studies diverse interdisciplinary areas revealing the general and individual qualities that dictate the strateg

  8. Perceptions of scientific research literature and strategies for reading papers depend on academic career stage.

    Science.gov (United States)

    Hubbard, Katharine E; Dunbar, Sonja D

    2017-01-01

    Reading primary research literature is an essential skill for all scientists and students on science degree programmes, however little is known about how researchers at different career stages interact with and interpret scientific papers. To explore this, we conducted a survey of 260 undergraduate students and researchers in Biological Sciences at a research intensive UK university. Responses to Likert scale questions demonstrated increases in confidence and skill with reading the literature between individuals at each career stage, including between postdoctoral researchers and faculty academics. The survey indicated that individuals at different career stages valued different sections of scientific papers, and skill in reading the results section develops slowly over the course of an academic career. Inexperienced readers found the methods and results sections of research papers the most difficult to read, and undervalued the importance of the results section and critical interpretation of data. These data highlight a need for structured support with reading scientific literature at multiple career stages, and for senior academics to be aware that junior colleagues may prioritise their reading differently. We propose a model for the development of literature processing skills, and consider the need for training strategies to help inexperienced readers engage with primary literature, and therefore develop important skills that underpin scientific careers. We also encourage researchers to be mindful of language used when writing papers, and to be more inclusive of diverse audiences when disseminating their work.

    1981-03-01

    This special research project was started in 1978 as five-year plan. The purposes are to clarify the aspect of radiation exposure in human bodies due to the radioactive substances brought into the environment regarding the utilization of atomic energy, its mechanism and various factors affecting it, and to contribute to the evaluation of exposure dose, the reduction of radiation exposure, the conditions of locating nuclear facilities and the improvement of the method of disposing radioactive wastes. In addition to the fields treated in the previous special research project, the experimental research concerning the metabolism of environmental radioactive nuclides in bodies, namely the problem of the peculiarity of radioactive nuclide kinetics in infants and fetuses different from adults and the possibility of causing the changes in the intake and metabolism of nuclides in foods by the difference in their states of existence, was newly included. Also the research concerning the method of evaluating the absorbed dose in human organs at the time of irradiation outside and inside bodies in a new subject. Accordingly, this special research project is composed of (1) the research concerning the radionuclide kinetics in the environment, (2) the research concerning the radionuclide kinetics in bodies, (3) the research concerning the measurement and evaluation of dose absorbed in internal organs due to environmental radiation, and (4) the research concerning the monitoring of low level environmental radiation. The results obtained so far are reported. (Kako, I.)

    Several techniques have been proposed for treating cervical spine instability due to rheumatoid arthritis. The aim of this study was to screen the different treatment options used in this pathology to evaluate the best form of treatment when the progression of rheumatoid disease affected the cranio-vertebral junction (CVJ) stability. The most important purpose of this study was to achieve both the efficacy of occipito-cervical fusion (OCF) to stabilize the occipitocervical junction and stop pannus progression. The authors describe their case example and stress, in the light of a literature review, the hypothesis that a stable biomechanical system extended to all the spaces involved, has both direct and indirect effects on RA pannus progression and the condition responsible for its formation, such as inflammation and articular hypermobility. Hence, the aim of this study is to advance this thesis, which may be extended to a wider statistical sample, with the same characteristics. A systematic literature research of case report articles, review articles, original articles, and prospective cohort studies, published from 1978 to 2011, was performed using PUBMED to analyze the different surgical strategies of RA involving CVJ and the role of OCF in these conditions. The key words used for the search the were: "inflammatory cervical pannus regression", "rheumatoid arthritis of the cranio-cervical junction", "occipito-cervical fusion", "treatment option in rheumatoid cervical instability", "altanto-axial dislocation", "craniovertebral junction" and "surgical technique". In addition, the authors reported their experience in a patient affected by erosive rheumatoid arthritis (ERA) with an anterior and posterior pannus involving C0-C1-C2. They decided to report this exemplative case to emphasize their own assumptions concerning the association between a posterior bony fusion, the arrest of anterior pannus progression and the improvement of functional outcome, without, however

    Arshad, Sidra; Hu, Shougeng; Ashraf, Badar Nadeem

    2018-02-01

    This study provides a systematic review of the existing literature on Zipf's law for city size distribution. Existing empirical evidence suggests that Zipf's law is not always observable even for the upper-tail cities of a territory. However, the controversy with empirical findings arises due to sample selection biases, methodological weaknesses and data limitations. The hypothesis of Zipf's law is more likely to be rejected for the entire city size distribution and, in such case, alternative distributions have been suggested. On the contrary, the hypothesis is more likely to be accepted if better empirical methods are employed and cities are properly defined. The debate is still far from to be conclusive. In addition, we identify four emerging areas in Zipf's law and city size distribution research including the size distribution of lower-tail cities, the size distribution of cities in sub-national regions, the alternative forms of Zipf's law, and the relationship between Zipf's law and the coherence property of the urban system.

    Beneath the different reasons for cervical masses, a spontaneous hemorrhage presents a rare and life-threatening condition. We present the rare case of a 62-year-old man who was presented with a dramatically enlarging cervical mass causing respiratory distress because of upper airway compression. An endotracheal intubation was lifesaving and avoided tracheotomy. A CT scan revealed a hematoma in the region of the left external carotid artery. An emergency angiography embolized a ruptured branch of the superior thyroid artery and surgery evacuated the hematoma. We discuss the rarity of the condition, reasons for a spontaneous rupture of the artery, and the diagnostic and treatment strategy. In addition, we review the literature on spontaneous thyroid artery hemorrhages, which, up to now, have been described only for the inferior thyroid artery. We conclude that the optimal management for cases of cervical hematoma is intubation, diagnosis, and angiography before surgery.

    Introduction. Endocarditis caused by yeasts is currently an emerging cause of infective endocarditis and, when accompanied byfever of unknown origin, is more severe since interferes with proper diagnosis and endocarditis treatment. Case presentation. The Rio de Janeiro Infective Endocarditis Study Group reports a case of infectious endocarditis (IE) with negative blood cultures in a 45-year-old white female resident in Rio de Janeiro, Brazil, previously submitted to kidney transplantation. After diagnosis and intervention, the valve culture revealed Rhodotorula mucilaginosa. The clinical aspects and overview of endocarditis caused by Rhodotorula spp. demonstrated that R. muscilaginosa have been isolated from the last IE cases from kidney transplanted patients. Conclusion. Though most of the patients (in literature) recovered well from endocarditis caused by Rhodotorula spp., physicians must be aware for diagnosis of fungemia and fungal treatment in kidney transplanted patients suffering of fever of unknown origin in the modern immunosuppressive treatment.

    2017-02-01

    The aim of this study is to provide a discussion on the definitions and conceptual dimensions of Responsible Research and Innovation based on findings from the literature. In the study, the outcomes of a literature review of 235 RRI-related articles were presented. The articles were selected from the EBSCO and Google Scholar databases regarding the definitions and dimensions of RRI. The results of the study indicated that while administrative definitions were widely quoted in the reviewed literature, they were not substantially further elaborated. Academic definitions were mostly derived from the institutional definitions; however, more empirical studies should be conducted in order to give a broader empirical basis to the development of the concept. In the current study, four distinct conceptual dimensions of RRI that appeared in the reviewed literature were brought out: inclusion, anticipation, responsiveness and reflexivity. Two emerging conceptual dimensions were also added: sustainability and care.

    2012-07-01

    Technological advances in clinical informatics have made large amounts of data accessible and potentially useful for research. As a result, a burgeoning literature addresses efforts to bridge the fields of health services research and biomedical informatics. The Electronic Data Methods Forum review examines peer-reviewed literature at the intersection of comparative effectiveness research and clinical informatics. The authors are specifically interested in characterizing this literature and identifying cross-cutting themes and gaps in the literature. A 3-step systematic literature search was conducted, including a structured search of PubMed, manual reviews of articles from selected publication lists, and manual reviews of research activities based on prospective electronic clinical data. Two thousand four hundred thirty-five citations were identified as potentially relevant. Ultimately, a full-text review was performed for 147 peer-reviewed papers. One hundred thirty-two articles were selected for inclusion in the review. Of these, 88 articles are the focus of the discussion in this paper. Three types of articles were identified, including papers that: (1) provide historical context or frameworks for using clinical informatics for research, (2) describe platforms and projects, and (3) discuss issues, challenges, and applications of natural language processing. In addition, 2 cross-cutting themes emerged: the challenges of conducting research in the absence of standardized ontologies and data collection; and unique data governance concerns related to the transfer, storage, deidentification, and access to electronic clinical data. Finally, the authors identified several current gaps on important topics such as the use of clinical informatics for cohort identification, cloud computing, and single point access to research data.

    A structured research programme is one of the main pillars of a trauma care system. Despite the high rate of injury-related mortalities, especially road traffic accidents, in Qatar, little consideration has been given to research in trauma. This review aimed to analyse research publications on the subject of trauma published from Qatar and to discuss the progress of clinical research in Qatar and the Gulf Cooperation Council countries with special emphasis on trauma research. A literature search using PubMed and Google Scholar search engines located 757 English-language articles within the fields of internal medicine, surgery and trauma originating from Qatar between the years 1993 and 2013. A steep increase in the number of trauma publications since 2010 could be linked to the setting up of a trauma research centre in Qatar in 2011. We believe that establishing a research unit has made a major impact on research productivity, which ultimately benefits health care.

    1984-03-01

    This special research was carried out for five years from fiscal 1978 to fiscal 1982, and its constitution was as follows: the investigation research on the behavior of radioactive substances in ocean and land environments, the investigation research on the metabolism of radioactive substances within bodies, the measurement of the dose absorbed in organs due to environmental radiation and the evaluation, and the investigation research on low level environmental radiation monitoring. As the sources of environmental radiation exposure, not only the release into the atmosphere and sea from nuclear power stations, nuclear fuel reprocessing plants and other facilities, but also the disposal of radioactive wastes on land and into ocean were considered. As the method of research, the experiment using living things and others, the analysis of the fallout nuclides existing in environment and living things, the analysis of the results of quantitative determination of stable elements and others were used. The detailed results of the above described researches are reported. By having executed this special research, the accumulation of new knowledge was obtained on the behavior of radioactive nuclides in environment and living things. (Kako, I.)

    Full Text Available Cushing’s syndrome (CS due to ectopic adrenocorticotrophic hormone (ACTH is associated with a variety of tumours most of which arise in the thorax or abdomen. Prostate carcinoma is a rare but important cause of rapidly progressive CS. To report a case of severe CS due to ACTH production from prostate neuroendocrine carcinoma and summarise previous published cases. A 71-year-old male presented with profound hypokalaemia, oedema and new onset hypertension. The patient reported two weeks of weight gain, muscle weakness, labile mood and insomnia. CS due to ectopic ACTH production was confirmed with failure to suppress cortisol levels following low- and high-dose dexamethasone suppression tests in the presence of a markedly elevated ACTH and a normal pituitary MRI. Computed tomography demonstrated an enlarged prostate with features of malignancy, confirmed by MRI. Subsequent prostatic biopsy confirmed neuroendocrine carcinoma of small cell type and conventional adenocarcinoma of the prostate. Adrenal steroidogenesis blockade was commenced using ketoconazole and metyrapone. Complete biochemical control of CS and evidence of disease regression on imaging occurred after four cycles of chemotherapy with carboplatin and etoposide. By the sixth cycle, the patient demonstrated radiological progression followed by recurrence of CS and died nine months after initial presentation. Prostate neuroendocrine carcinoma is a rare cause of CS that can be rapidly fatal, and early aggressive treatment of the CS is important. In CS where the cause of EAS is unable to be identified, a pelvic source should be considered and imaging of the pelvis carefully reviewed.

    Full Text Available The purpose of this paper is to determine the range of research paradigms employed in a smaller subset of Information Systems (IS literature, namely Enterprise Resource Planning (ERP systems. A systematic literature review based on papers that mentioned ERPs was drawn from eight of the most highly ranked journals according to their h-index. The findings indicate that the majority (96.6% of the ERP research papers were conducted within a positivist research paradigm, which is a far higher proportion than is suggested by other research in the general IS literature (approximately 81%. This paper suggests that there is a strong case for ERP researchers to look at existing paradigm selection and how effectively their research relates to the ERP body of knowledge, especially in respect to the issues of importance to managers within organizations (notably social and change management issues. This research also identified areas where existing paradigm evaluation methods could be enhanced and refined in respect to non-positivist classifications.

    Massive gastrointestinal bleeding is an emergency that can sometimes require immediate surgery. We report the first case, to the best of our knowledge, of massive rectal bleeding due to Yersinia enterocolitica, requiring ileocecal resection. A 41-year-old North African woman was admitted to our emergency department for massive rectal bleeding. She had a history of an iron deficiency anemia of unknown cause, and diarrhea 2 months before the admission. On admission to our emergency unit, she was in a state of hemodynamic collapse. An examination showed discolored conjunctivas, massive rectal bleeding with clots and no abdominal pain. The first medical treatment included the use of noradrenaline. An upper gastrointestinal endoscopy was performed and did not show any lesions. Computed tomography of her abdomen showed significant and hypervascular wall thickening of her terminal ileum suggestive of a tumor. Because her massive rectal bleeding worsened and her collapse persisted, an exploratory laparotomy and ileocecal resection were immediately performed on the patient. Histopathological analysis showed enteritis caused by Yersinia enterocolitica. Her outcome was favorable. Enteritis due to Yersinia enterocolitica can take a pseudotumoral form and mislead the diagnosis of gastrointestinal bleeding.

    There are two clues in academic inheritance of acupuncture, including theoretical inheritance and empirical inheritance. Up to now, the mainstream of acupuncture theory has not been in conformity with empirical clinic, and could not explain new clinical techniques. The existing acupuncture theories are in need of strict re-examination, and new academic achievements shall be carefully absorbed. The literature review, concepts research and academic history study are considered as key pathways of acupuncture theory research.

    Science.gov (United States)

    Varda, Danielle; Shoup, Jo Ann; Miller, Sara

    2012-03-01

    We explored and analyzed how findings from public affairs research can inform public health research and practice, specifically in the area of interorganizational collaboration, one of the most promising practice-based approaches in the public health field. We conducted a systematic review of the public affairs literature by following a grounded theory approach. We coded 151 articles for demographics and empirical findings (n = 258). Three primary findings stand out in the public affairs literature: network structure affects governance, management strategies exist for administrators, and collaboration can be linked to outcomes. These findings are linked to priorities in public health practice. Overall, we found that public affairs has a long and rich history of research in collaborations that offers unique organizational theory and management tools to public health practitioners.

    2017-01-01

    Full Text Available Objective: Ishemic bone disease has multifactorial etiologies. Cronic dental infections should be eliminated to prevent osteonecrosis of the jaw. Case report: We report an unusual case of osteonecrosis due to the pulpal-peridontal syndrome and subsequent pulp necrosis. A case of 38 year old woman who presented with exposed bone, 8 mm in diameter, in the lingual area of the right lower third molar. The patient was otherwise healthy and was not taking any medications. A detailed medical history showed no previous diseases. Patient denied any type of local trauma. A complete blood count showed no abnormalities. The panoramic radiograph revealed a deep periodontal pocket between teeth 47 and 48. The CBCT revealed a deep periodontal pocket between molars and bone sequestrum of the lingual plate. Topical treatment consisted of adhesive periodontal dressing based on the cellulose and betamethasone oitnment together with orabase, without improvement. Therefore, peroral amoxycillin was prescribed for a week. Since there was no improvement, the third molar was removed as well as necrotic bone; the alveolar bone was remodelled and utures were placed. After suturing, the whole area was covered using intraoral resorbable bandage. Microbial swab of the wound aspirate did not reveal polymorphonuclears or the presence of icroorganisms. Microbial swab of the biopsy specimen of the necrotic bone particle and sequestrum showed a large amount of gram-positive coccae, however, polymorphonuclears were not found. Histopathological analysis revealed acute chronic inflammation. One week after the surgery, the area healed completely. Conclusion: This case highlights the fact that in some patients bone exposure might develop due to the pulpal-peridontal syndrome i.e. pulp necrosis.

    INTRODUCTION. Infection by the Epstein-Barr virus (EBV) -either as a primary infection, a reactivation or an active chronic infection- can give rise to several clinical forms of involvement of the central nervous system. We report a case of encephalitis due to EBV produced by viral reactivation in an immunocompetent patient which initially mimicked, from the clinical and electroencephalographic point of view, encephalitis due to type 1 herpes simplex virus (HSV-1). CASE REPORT. A 51-year-old male who had reported the presence of dorsal herpes zoster some days earlier. The patient visited the emergency department after suffering a holocranial oppressive headache and febricula for seven days; 24 hours before admission to hospital, he was suffering from drowsiness and language disorder. The neurological examination revealed stiffness in the back of the neck and dysphasia. An analysis of the cerebrospinal fluid revealed pleocytosis (422 cells/mm(3)) with 98% of mononuclear cells and normal protein and glucose concentration levels in cerebrospinal fluid. Magnetic resonance imaging of the brain and electroencephalogram readings were normal with periodic lateralised epileptiform discharges in the left temporal region. Intravenous acyclovir treatment was initiated, but renal failure meant it had to be changed to oral valaciclovir with clinical resolution and improvement of the liquoral parameters. Polymerase chain reaction in the cerebrospinal fluid was positive for EBV and negative for the other neurotropic viruses. In blood, the serology test for EBV with IgG was positive, while IgM and heterophile antibody tests were negative. CONCLUSIONS. EBV infection can give rise to acute disseminated encephalomyelitis or affect several locations in the central nervous system, especially the cerebellum. Clinical pictures mimicking HSV-1 are less frequent. When encephalitis is related to viral reactivation, precipitating factors can be detected, as in our case.

    2015-01-01

    Qualitative research is appearing with increasing frequency in the public health and medical literature. Qualitative research in combination with a community-based participatory research (CBPR) approach can be powerful. However little guidance is available on how to present qualitative research within a CBPR framework for peer-review publications. This article provides a brief overview of how qualitative research can advance CBPR partnerships and outlines practical guidelines for writing for publication about qualitative research within a CBPR framework to (1) guide partners with little experience publishing in peer-reviewed journals and/or (2) facilitate effective preparation of manuscripts grounded in qualitative research for peer-reviewed journals. We provide information regarding the specific benefits of qualitative inquiry in CBPR, tips for organizing the manuscript, questions to consider in preparing the manuscript, common mistakes in the presentation of qualitative research, and examples of peer-reviewed manuscripts presenting qualitative research conducted within a CBPR framework. Qualitative research approaches have tremendous potential to integrate community and researcher perspectives to inform community health research findings. Effective dissemination of CBPR informed qualitative research findings is crucial to advancing health disparities research.

  19. Exertional Angina Due To Fused Aortic Bioprosthesis During Left Ventricular Assist Device Support: Two Cases and Review of the Literature.

    Bonios, Michael J; Selzman, Craig H; Gilbert, Edward M; McKellar, Stephen H; Koliopoulou, Antigoni; Strege, Jennifer L; Nativi, Jose N; Fang, James C; Stehlik, Josef; Drakos, Stavros G

    We present the case of two patients with idiopathic dilated cardiomyopathy and moderate aortic valve regurgitation that were treated with a bioprosthetic valve at the time of the left ventricular assist device (LVAD) implantation. A few months later, patients revealed partial recovery in the left ventricle systolic function. Both patients, during the LVAD turndown protocol, reported the onset of chest pain. The transthoracic echocardiography revealed the presence of a new transaortic pressure gradient. We confirmed the presence of a fused bioprosthetic valve by further performing a transesophageal echocardiogram and a left and right heart catheterization. Replacement of aortic valve at the time of an LVAD implantation constitutes a challenging case. Although a mechanical valve is contraindicated due to the increased thromboembolic risk, selecting a bioprosthetic valve increases the risk of valve leaflets fusion. The consequences of this phenomenon should be acknowledged in LVAD patients undergoing aortic valve replacement with a bioprosthetic, especially under the view of LVAD explantation for those revealing myocardial recovery under mechanical unloading.

    2013-01-01

    Nutrigenomics and nutrigenetics (NGx) are fields of research that have raised significant expectations about their potential benefits. This article presents empirical data from an online survey seeking the opinions of NGx researchers (n=126) regarding the achievability of the potential benefits of NGx, the time envisioned for their realization, the motives that may lead to their explicit mention in scientific peer-reviewed articles and the audience(s) targeted by NGx researchers when reporting their results in such articles. Results show that caution should be taken to avoid the risks associated with biohype and the premature dissemination of the potential benefits of NGx among various audiences.

    The study protocol is the core document of every clinical research project. Clinical research in studies involving surgical interventions presents some specific challenges, which need to be accounted for and described in the study protocol. The aim of this review is to provide a practical guide for developing a clinical study protocol for surgical interventions with a focus on methodologic issues. On the basis of an in-depth literature search of methodologic literature and on some cardinal published surgical trials and observational studies, the authors provides a 10-step guide for developing a clinical study protocol in surgery. This practical guide outlines key methodologic issues important when planning an ethically and scientifically sound research project involving surgical interventions, with the ultimate goal of providing high-level evidence relevant for health care decision making in surgery.

    2018-02-01

    Full Text Available This paper presents an analysis of the literature concerning the impact of corporate sustainability on corporate financial performance. The relationship between corporate sustainable practices and financial performance has received growing attention in research, yet a consensus remains elusive. This paper identifies developing trends and the issues that hinder conclusive consensus on that relationship. We used content analysis to examine the literature and establish the current state of research. A total of 132 papers from top-tier journals are shortlisted. We find that 78% of publications report a positive relationship between corporate sustainability and financial performance. Variations in research methodology and measurement of variables lead to the divergent views on the relationship. Furthermore, literature is slowly replacing total sustainability with narrower corporate social responsibility (CSR, which is dominated by the social dimension of sustainability, while encompassing little to nothing of environmental and economic dimensions. Studies from developing countries remain scarce. More research is needed to facilitate convergence in the understanding of the relationship between corporate sustainable practices and financial performance.

  3. A systematic literature review of neuroimaging research on developmental stuttering between 1995 and 2016.

    2018-03-01

    Stuttering is a disorder that affects millions of people all over the world. Over the past two decades, there has been a great deal of interest in investigating the neural basis of the disorder. This systematic literature review is intended to provide a comprehensive summary of the neuroimaging literature on developmental stuttering. It is a resource for researchers to quickly and easily identify relevant studies for their areas of interest and enable them to determine the most appropriate methodology to utilize in their work. The review also highlights gaps in the literature in terms of methodology and areas of research. We conducted a systematic literature review on neuroimaging studies on developmental stuttering according to the PRISMA guidelines. We searched for articles in the pubmed database containing "stuttering" OR "stammering" AND either "MRI", "PET", "EEG", "MEG", "TMS"or "brain" that were published between 1995/​01/​01 and 2016/​01/​01. The search returned a total of 359 items with an additional 26 identified from a manual search. Of these, there were a total of 111 full text articles that met criteria for inclusion in the systematic literature review. We also discuss neuroimaging studies on developmental stuttering published throughout 2016. The discussion of the results is organized first by methodology and second by population (i.e., adults or children) and includes tables that contain all items returned by the search. There are widespread abnormalities in the structural architecture and functional organization of the brains of adults and children who stutter. These are evident not only in speech tasks, but also non-speech tasks. Future research should make greater use of functional neuroimaging and noninvasive brain stimulation, and employ structural methodologies that have greater sensitivity. Newly planned studies should also investigate sex differences, focus on augmenting treatment, examine moments of dysfluency and longitudinally or

    Alexandra Amado

    2018-01-01

    Full Text Available Given the research interest on Big Data in Marketing, we present a research literature analysis based on a text mining semi-automated approach with the goal of identifying the main trends in this domain. In particular, the analysis focuses on relevant terms and topics related with five dimensions: Big Data, Marketing, Geographic location of authors’ affiliation (countries and continents, Products, and Sectors. A total of 1560 articles published from 2010 to 2015 were scrutinized. The findings revealed that research is bipartite between technological and research domains, with Big Data publications not clearly aligning cutting edge techniques toward Marketing benefits. Also, few inter-continental co-authored publications were found. Moreover, findings show that research in Big Data applications to Marketing is still in an embryonic stage, thus making it essential to develop more direct efforts toward business for Big Data to thrive in the Marketing arena.

  8. Literature Review of Enterprise Systems Research Using Institutional Theory: Towards a Conceptual Model

    DEFF Research Database (Denmark)

    Svejvig, Per

    This paper sets out to examine the use of institutional theory as a conceptually rich lens to study social issues of enterprise systems (ES) research. More precisely, the purpose is to categorize current ES research using institutional theory to develop a conceptual model that advances ES research...... model which advocates for multi-level and multi-theory approaches, and applies newer institutional aspects such as institutional logics. The findings show that institutional theory in ES research is in its infancy and adopts mainly traditional institutional aspects like isomorphism....... Key institutional features are presented such as isomorphism, rationalized myths, bridging macro and micro structures, and institutional logics and their implications for ES research are discussed. Through a literature review of 180 articles, of which 18 papers are selected, we build a conceptual...

  9. Why students leave in the UK: an integrative review of the international research literature.

    The purpose of this integrative review of the literature was to find and review international research studies that explored student attrition to determine what is known about the topic and to identify gaps in the research with a view to addressing the situation in the UK. Attrition from nursing programmes is a serious problem in the UK. It is recognised as a complex phenomenon, not attributable to a single cause. Regardless of actual attrition rates and trends, departments of nursing are challenged to perform in a business-like manner. Consequently, every student lost to a programme of study equates to a financial penalty for the department and to the future workforce and community.   Integrative review of the literature. Using electronic databases and specific search terms, 18 articles were identified and reviewed. Findings from the identified international research literature were analysed using qualitative content analysis. Four broad themes that accounted for factors of relevance to attrition were identified: Social, Prediction, Programme and Personal. Retention studies are fraught with methodological problems. These include incomplete or inaccurate data and low response rates. Attrition early in programmes may be attributed to a failure to understand the roles of nurses in contemporary societies. This has led to dissatisfaction with programmes and academic failure, as students may underestimate the intellectual demands of their programmes. Attrition later in the programme may be attributed to a combination of personal factors that culminate in a personal crisis. The research literature suggests that stereotyping of nurses is a major factor in attrition. Both professions need to find ways of communicating contemporary roles to wider society. © 2010 Blackwell Publishing Ltd.

    2012-01-01

    Background Elderly care practice and its management together with policy and research play a crucial role in responding to increasing challenges in institutional care for elderly people. Successful dialogue between these is necessary. The purpose of this systematic literature review is to compare how institutional elderly care management research meets the care challenges currently emphasized in international long-term care policy documents. Methods This paper was based on a systematic literature review. After screening 1971 abstracts using inclusion/exclusion criteria, 58 refereed articles published between 2000 and 2010 remained for analysis. The articles were analyzed using theory-based content analysis by comparing the results to the framework based on analysis of international long-term care management policy documents. Results The current challenges of long-term care management identified from policy documents were Integrated Care Management, Productivity Management, Quality Management, Workforce Management and ICT Management. The research on institutional elderly care management responded somewhat to the challenges mentioned in policy documents. However, some of the challenges were studied broadly and some were paid only minor attention. Further, only few studies focused on the core items of challenges addressed in policy documents. Conclusions Institutional care management research needs to focus more on challenges in integrated care, productivity, ICT and division of labor. Managers, researchers and policy-makers should assume more active collaborative roles in processes of research, policymaking and policy implementation. In addition managers’ and policymakers’ scientific literacy needs to be enhanced. PMID:23137416

    Elderly care practice and its management together with policy and research play a crucial role in responding to increasing challenges in institutional care for elderly people. Successful dialogue between these is necessary. The purpose of this systematic literature review is to compare how institutional elderly care management research meets the care challenges currently emphasized in international long-term care policy documents. This paper was based on a systematic literature review. After screening 1971 abstracts using inclusion/exclusion criteria, 58 refereed articles published between 2000 and 2010 remained for analysis. The articles were analyzed using theory-based content analysis by comparing the results to the framework based on analysis of international long-term care management policy documents. The current challenges of long-term care management identified from policy documents were Integrated Care Management, Productivity Management, Quality Management, Workforce Management and ICT Management. The research on institutional elderly care management responded somewhat to the challenges mentioned in policy documents. However, some of the challenges were studied broadly and some were paid only minor attention. Further, only few studies focused on the core items of challenges addressed in policy documents. Institutional care management research needs to focus more on challenges in integrated care, productivity, ICT and division of labor. Managers, researchers and policy-makers should assume more active collaborative roles in processes of research, policymaking and policy implementation. In addition managers' and policymakers' scientific literacy needs to be enhanced.

    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.

  15. Teaching Earth Sciences as an interdisciplinary subject: Novel module design involving research literature

    2010-05-01

    The study of Earth Sciences requires an interdisciplinary approach as it involves understanding scientific knowledge originating from a wide spectrum of research areas. Not only does it include subjects ranging from, for instance, hydrogeology to deep crustal seismology and from climate science to oceanography, but it also has many direct applications in closely related disciplines such as environmental engineering and natural resources management. While research crossing traditional disciplinary boundaries in geosciences is becoming increasingly common, there is only limited integration of interdisciplinary research in the teaching of the subject. Given that the transition from undergraduate education based on subject modules to postgraduate interdisciplinary research is never easy, such integration is a highly desirable pedagogical approach at both undergraduate and postgraduate levels. My presentation is based on a recent teaching project involving novel design of an undergraduate course. The course is implemented in order to address the synergy between research and teaching (Tong, 2009). This project has been shown to be effective and successful in teaching geosciences undergraduates at the University of London. The module consists of studying core geophysical principles and linking them directly to a selection of recently published research papers in a wide range of interdisciplinary applications. Research reviewing and reporting techniques are systematically developed, practised and fully integrated into teaching of the core scientific theories. A fully-aligned assignment with a feedback website invites the students to reflect on the scientific knowledge and the study skills related to research literature they have acquired in the course. This teaching project has been recognized by a teaching award (http://www.clpd.bbk.ac.uk/staff/BETA). In this presentation, I will discuss how undergraduate teaching with a focus on research literature in Earth Sciences can

    To review the published, peer-reviewed literature on clinical research data warehouse governance in distributed research networks (DRNs). Medline, PubMed, EMBASE, CINAHL, and INSPEC were searched for relevant documents published through July 31, 2013 using a systematic approach. Only documents relating to DRNs in the USA were included. Documents were analyzed using a classification framework consisting of 10 facets to identify themes. 6641 documents were retrieved. After screening for duplicates and relevance, 38 were included in the final review. A peer-reviewed literature on data warehouse governance is emerging, but is still sparse. Peer-reviewed publications on UK research network governance were more prevalent, although not reviewed for this analysis. All 10 classification facets were used, with some documents falling into two or more classifications. No document addressed costs associated with governance. Even though DRNs are emerging as vehicles for research and public health surveillance, understanding of DRN data governance policies and procedures is limited. This is expected to change as more DRN projects disseminate their governance approaches as publicly available toolkits and peer-reviewed publications. While peer-reviewed, US-based DRN data warehouse governance publications have increased, DRN developers and administrators are encouraged to publish information about these programs.

    2015-01-01

    Full Text Available In the work we examine the possibility of application of productive research tasks in working with gifted students in teaching Serbian language and literature. Using specific examples of interpretations of literary works we show that productive research assignments encourage students' creative and inventive expression, creativity, imagination and criticality and enable them to develop in accordance with their personality, individual preferences and abilities. In the examples of their use in problem solving, we determine how productive research tasks are conducive to gifted students who need to learn through problem solving and school work and to experience learning as a challenge. They present the basis for independent research, which allows gifted students to express their own creativity and the need to acquire new, challenging knowledge, and represent a powerful motivational tool that teachers can use in order to further develop their talent. Creative application of the productive research tasks in teaching Serbian language and literature is the possibility that the education of gifted students is not treated as elitist question, but to transform teaching process into development of giftedness and talent, where the role of the teacher in the teaching process rises to the role of the mentor.

    2014-11-01

    Full Text Available System dynamics is a strategic approach for modeling complex systems and analyzing their behavior. Dynamic behavior in entrepreneurial system can be modeled using System Dynamics Approach and dynamic hypotheses about the system`s behavior can be proposed and tested using simulation and computer aided tools. However, as the review of literature shows, studies which link system dynamics modeling with entrepreneurship are rare and fragmented. This article presents a review of studies on the subject followed by integration and discussion on main research issues that have been the focus of previous studies. The main aim of this review is to categorize the available research related to the application of system dynamics modeling in entrepreneurship to integrate research and enable recommendations for future research. The Results reveal that the previous research could be categorized under a two dimensional taxonomy composed of level of analysis and level of modeling. The Level of analysis has three categories: micro level, meso level and macro level. The Level of modeling has six hierarchical levels. This study identifies several gaps in the literature and discusses the future directions in this field.

    To establish how common and impactful nursing and healthcare ageism is and whether proven interventions or prevention methods exist. Ageism has been a concern since 1969 when it was first introduced as a concept for social reform. As ageism has been linked to lower quality health services and reduced health care access, it is imperative that healthcare and nursing ageism is prevented or identified and reduced or eliminated. A qualitative narrative review of published research literature reviews using a scoping design to map all published reviews was undertaken. The EBSCO Discovery Service (providing access to articles in 271 databases, including MEDLINE and CINAHL) and Directory of Open Access Journals (providing access to over 9,000 open access journals) were used to find review articles. Using predetermined inclusion and exclusion criteria, and limited by English language and peer-review publications, 12 eligible reviews were identified and information from them was systematically identified, assessed and synthesised. The 12 reviews did not provide clear and convincing information to determine how common and impactful nursing or healthcare ageism is, nor what can best be done to prevent or address it. Although each review had value since research literature was collected and discussed on nursing or healthcare ageism, the array of literature search and analysis methods, and diversity in conclusions reached about the evidence is highly problematic. Research literature reviews offering a more balanced perspective and demonstrating greater care in finding and using quality evidence are needed. At this point in time, there is no clear understanding of how widespread and impactful nursing or healthcare ageism is, and what can best be done to prevent or address it. Nurses need to be aware that ageism may be common and impactful, and guard against it. © 2017 John Wiley & Sons Ltd.

  20. A LITERATURE REVIEW ON CAUSE-RELATED MARKETING STRATEGIC ORIENTATION IN BUSINESS RESEARCH

    Directory of Open Access Journals (Sweden)

    Marcela Sefora Sana

    2015-07-01

    Full Text Available A long time economic and social objectives have been seen as competing, but academic researchers underline that this two directions may converge in certain situations. Companies belong to communities where they develop their activities. When the social goals of the communities are related to the main objectives of the company, sustaining a social cause could produce economic benefits, in this case corporate philanthropy and shareholders interest take the same direction. Cause-related marketing is a marketing concept that gained more interest in the last three decades and exemplifies how social and economic objectives are achieved in a strategic manner in promoting campaigns. Researches in business and non-profit organizations reveal that cause-related marketing campaigns sustain the growth of market share and sales, and help at improving brands image. More and more companies and non-profit organizations find cause-related marketing as a strategic tool suitable for building long term relations to the customers, for increasing brand awareness, for gaining a social responsible corporative image, for supporting local community or for producing transformation in sustaining causes at global or international level. The study analyses the definitions of cause-related marketing the presence and evolution of the concept in the academic literature, and marketing terms that are connected more often to this concept. Comparative to non-profit marketing concept, cause-related marketing gained a larger interest in literature. On the other side, corporate philanthropy is still a concept that gains more interest than cause-related marketing in academic literature, being a more commune way used by companies in collaboration to non-profit organizations. Tided to cause-related marketing concept literature review reveals concepts as: consumer behaviour, brand image and corporate social responsibility being more often analysed.

    2008-06-01

    What does the publicly available literature tell us about the attitudes of health care staff to the development of information technology in practice, including the factors which influence them and the factors which may be used to change these attitudes? Twelve databases were searched for literature published between 2000 and 2005 that identified research related to information technology (IT), health professionals and attitude. English language studies were included which described primary research relating to the attitudes of one or more health care staff groups towards IT. Letters, personal viewpoints, reflections and opinion pieces were not included. Complex factors contribute to the formation of attitudes towards IT. Many of the issues identified were around the flexibility of the systems and whether they were 'fit for purpose', along with the confidence and experience of the IT users. The literature suggests that attitudes of practitioners are a significant factor in the acceptance and efficiency of use of IT in practice. The literature also suggested that education and training was a factor for encouraging the use of IT systems. A range of key issues, such as the need for flexibility and usability, appropriate education and training and the need for the software to be 'fit for purpose', showed that organizations need to plan carefully when proposing the introduction of IT-based systems into work practices. The studies reviewed did suggest that attitudes of health care professionals can be a significant factor in the acceptance and efficiency of use of IT in practice. Further qualitative and quantitative research is needed into the approaches that have most effect on the attitudes of health care staff towards IT.

    2018-02-09

    To review the scientific literature examining gambling behavior in military veterans in order to summarize factors associated with gambling behavior in this population. Database searches were employed to identify articles specifically examining gambling behavior in military veterans. Cumulative search results identified 52 articles (1983-2017) examining gambling behavior in veteran populations. Articles generally fell into one or more of the following categories: prevalence, psychological profiles and psychiatric comorbidities, treatment evaluations, measurement, and genetic contributions to gambling disorder. Results from reviewed articles are presented and implications for future research discussed. Research to date has provided an excellent foundation to inform potential screening, intervention and research activities going forward. The authors suggest that a public health approach to future research endeavors would strengthen the evidence base regarding gambling in veteran populations and better inform strategies for screening, prevention and treatment.

  4. Knowledge Management in Startups: Systematic Literature Review and Future Research Agenda

    Directory of Open Access Journals (Sweden)

    Piera Centobelli

    2017-03-01

    Full Text Available This paper conducts a systematic literature review on knowledge management (KM in the context of startups in order to analyze the state of the art, identify research gaps and define a future research agenda. The main findings highlight that, even though there is an increasing number of papers on the topic of KM in startups, several issues are still neglected. Specifically, the paper identifies four main gaps in the body of literature. The first gap deals with the environmental and socio-political factors influencing the adoption of KM in startups. The second gap regards the lack of a comprehensive taxonomy of knowledge management systems (KMSs that may support the processes of knowledge creation, acquisition, storage, transfer, sharing and application. This second gap allows us to identify a third gap concerning the level of alignment between startup’s strategies and technologies adopted. Finally, the fourth gap deals with the issue of the impact of KM on startup’s performances with regard to economic, financial, market, technical, technological, organizational, human and relational performance. From these four gaps, six research questions (RQs have been proposed. These RQs allow us to identify possible areas of analysis to define a future research agenda. Neglecting these issues means underestimating all the possible advantages of KM adoption for a startup to achieve efficiency, effectiveness and scalability goals.

    Contributing to health informatics research means using conceptual models that are integrative and explain the research in terms of the two broad domains of health science and information science. However, it can be hard for novice health informatics researchers to find exemplars and guidelines in working with integrative conceptual models. The aim of this paper is to support the use of integrative conceptual models in research on information and communication technologies in the health sector, and to encourage discussion of these conceptual models in scholarly forums. A two-part method was used to summarize and structure ideas about how to work effectively with conceptual models in health informatics research that included (1) a selective review and summary of the literature of conceptual models; and (2) the construction of a step-by-step approach to developing a conceptual model. The seven-step methodology for developing conceptual models in health informatics research explained in this paper involves (1) acknowledging the limitations of health science and information science conceptual models; (2) giving a rationale for one's choice of integrative conceptual model; (3) explicating a conceptual model verbally and graphically; (4) seeking feedback about the conceptual model from stakeholders in both the health science and information science domains; (5) aligning a conceptual model with an appropriate research plan; (6) adapting a conceptual model in response to new knowledge over time; and (7) disseminating conceptual models in scholarly and scientific forums. Making explicit the conceptual model that underpins a health informatics research project can contribute to increasing the number of well-formed and strongly grounded health informatics research projects. This explication has distinct benefits for researchers in training, research teams, and researchers and practitioners in information, health, and other disciplines.

    To perform a structured literature review of the published empirical research on informed consent with older adults in order to make recommendations to improve the informed consent process and to highlight areas needing further examination. Relevant literature was identified by searching electronic databases (AGELINE, BIOETHICSLINE, CancerLit, Ethics Index, Health, LegalTrac, MEDLINE, PAIS International, PsycInfo, and Sociofile). Studies were included if they were reports of primary research data about informed consent and, if patients or other subjects were used, older subjects were included in the sample. Data related to the aspect of informed consent under study (recruitment, decision-making capacity, voluntariness, disclosure of information, understanding of information, consent forms, authorization, and policies and procedures) were abstracted and entered into a specially designed database. Characterization of the population, age of subjects, setting, whether informed consent was being studied in the context of research or treatment, study design, the nature of outcome or dependent variables, independent variables (e.g., experimental conditions in a randomized controlled trial or patient/subject characteristics in a nonrandomized comparison), and results according to the aspect of informed consent under study. A total of 99 articles met all the inclusion criteria and posed 289 unique research questions covering a wide range of aspects of informed consent: recruitment (60); decision making capacity (21); voluntariness (6); disclosure (30); understanding (139); consent forms (7); authorization (11); policies (13); and other (2). In the secondary analyses of numerous studies, diminished understanding of informed consent information was associated with older age and fewer years of education. Older age was also sometimes associated with decreased participation in research. Studies of disclosure of informed consent information suggest strategies to improve

    Full Text Available This article reviews the literature on research conducted during the last two decades on traffic noise impacts in India. Road traffic noise studies in India are fewer and restricted only to the metropolitan areas. The studies over the years have also focused on the monitoring, recording, analysis, modeling, and to some extent mapping related themes. Negligible studies are observed in areas of physiological and sleep research exposure-effect context. Most impact studies have been associated with annoyance and attitudinal surveys only. Little scientific literature exists related to effects of traffic noise on human physiology in the Indian context. The findings of this review search and analysis observe that very little studies are available relating to traffic noise and health impacts. All of them are subjective response studies and only a small portion of them quantify the exposure-effect chain and model the noise index with annoyance. The review of papers showed that road traffic noise is a cause for annoyance to a variety of degree among the respondents. A generalization of impacts and meta-analysis was not possible due to variability of the study designs and outputs preferred.

    2017-11-29

    Demographic change has increased the need for research on healthcare for older people. Recently there has been a growing awareness that research might benefit from actively involving patients and the public in study design and conduct. Besides empowering patients and democratizing research, involvement enhances the quality of research and the development of equitable healthcare solutions. Little is known about how to involve older people. This review aims to support scientists intending to involve older people in health research by systematically identifying and describing studies involving older people and analyzing associated facilitators and challenges. Old people were operationalized as people living with old-age-related conditions. We conducted a systematic search in PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane library for the period 2007 to July 2017 and also manually searched reference lists of the nine retrieved articles and other relevant sources. While involvement of older people in research is feasible, specific challenges related to this group need be taken into account. Strategies to enhance effective involvement comprise a thoughtful choice of location, use of visualization and accessible communication, building good relationships and flexible approaches. Further research is needed on the involvement of people in care homes or with vision, hearing or mobility limitations.

    2014-12-01

    Research utilization (RU), is an important strategy to promote the quality of patient care. The aim of this study was to present a comprehensive literature review describing barriers and facilitators of RU among Iranian nurses. Literature review was undertaken using the international databases including Pub Med/Medline, Scopus, Science Direct, and Google Scholar. Also, Persian electronic databases such as Magiran, SID and Iran Medex were searched up to May 2014. The search was limited to articles in the English and Persian languages that evaluate the barriers or facilitators of RU among Iranian nurses. A total of 11 articles were in the final dataset. The most important barriers to RU among Iranian nurses were related to the organization factors such as inadequate facilities; insufficient time on the job, lack of authority, physician cooperation, and administrative support. The most frequent facilitators of RU were education in enhancing nurses knowledge and skills in research evaluation, support from knowledgeable nursing colleagues and nursing faculty in the clinical setting, access to an expert committee for clinical appraisal, improving skills in English language and searching for articles, sufficient economic resources to carry out research, and having access to more facilities such as internet. Iranian nurses encounter with the same difficulties as to other countries regarding RU; while setting related barriers were the predominant obstacles to RU among them. Therefore, health managers are expected to plan appropriate strategies to smooth the progress of RU by nurses in their practice.

    2014-12-01

    Full Text Available This research focuses on the Hybrid Flow Shop production scheduling problem, which is one of the most difficult problems to solve. The literature points to several studies that focus the Hybrid Flow Shop scheduling problem with monocriteria functions. Despite of the fact that, many real world problems involve several objective functions, they can often compete and conflict, leading researchers to concentrate direct their efforts on the development of methods that take consider this variant into consideration. The goal of the study is to review and analyze the methods in order to solve the Hybrid Flow Shop production scheduling problem with multicriteria functions in the literature. The analyses were performed using several papers that have been published over the years, also the parallel machines types, the approach used to develop solution methods, the type of method develop, the objective function, the performance criterion adopted, and the additional constraints considered. The results of the reviewing and analysis of 46 papers showed opportunities for future research on this topic, including the following: (i use uniform and dedicated parallel machines, (ii use exact and metaheuristics approaches, (iv develop lower and uppers bounds, relations of dominance and different search strategies to improve the computational time of the exact methods,  (v develop  other types of metaheuristic, (vi work with anticipatory setups, and (vii add constraints faced by the production systems itself.

    Medication administration is an important and essential nursing function with the potential for dangerous consequences if errors occur. Not only must nurses understand the use and outcomes of administering medications they must be able to calculate correct dosages. Medication administration and dosage calculation education occurs across the undergraduate program for student nurses. Research highlights inconsistencies in the approaches used by academics to enhance the student nurse's medication calculation abilities. The aim of this integrative review was to examine the literature available on effective education strategies for undergraduate student nurses on medication dosage calculations. A literature search of five health care databases: Sciencedirect, Cinahl, Pubmed, Proquest, Medline to identify journal articles between 1990 and 2012 was conducted. Research articles on medication calculation educational strategies were considered for inclusion in this review. The search yielded 266 papers of which 20 meet the inclusion criteria. A total of 5206 student nurse were included in the final review. The review revealed educational strategies fell into four types of strategies; traditional pedagogy, technology, psychomotor skills and blended learning. The results suggested student nurses showed some benefit from the different strategies; however more improvements could be made. More rigorous research into this area is needed.

    Hemolytic disease of the fetus and newborn (HDFN) attributed to M/N-incompatibility varies from asymptomatic to lethally hydropic. Case reports are rare, and the clinical significance of anti-M is not completely understood. A challenging case of HDFN due to anti-M prompted an investigation of the Japanese literature, in order to characterize the clinical spectrum of M/N-incompatibility pregnancies in Japan and report results to English-language readers. Japanese reports of HDFN attributed to M/N incompatibility were compiled. Abstracted data include maternal antibody titers at delivery, fetal direct antiglobulin test, hemoglobin, total bilirubin, reticulocyte count at birth, and therapeutic interventions. We investigated characteristics of HDFN due to M/N-incompatible pregnancies in Japan after encountering a case of severe HDFN along with late-onset anemia in an infant born to a woman carrying IgG anti-M with a titer of 1. In total, thirty-three babies with HDFN due to anti-M and one due to anti-N have been reported in Japan since 1975. The median maternal antibody titer was 64 at delivery and was 16 or less in 10 of 34 women (29%). Five of 34 babies (15%) were stillborn or died as neonates. Twenty-one of 29 survivors (72%) had severe hemolytic anemia and/or hydrops fetalis. The reticulocyte count of neonates with anemia stayed below the reference interval. Sixteen (55%) developed late-onset anemia and 14 (48%) were transfused with M-negative RBCs. Significant positive correlation (P hemolytic anemia and/or hydrops fetalis. Low reticulocyte count in neonates with late-onset anemia is consistent with suppressed erythropoiesis due to anti-M. © 2013.

    inform this debate by investigating research approaches used in SoTL publications. We analysed 223 empirical research studies published from 2012 to 2014 in three explicitly focused SoTL journals. We classified the studies as either qualitative, quantitative, or mixed methods using an analytical framework devised from existing literature on research methods. We found that the use of the three research designs was fairly evenly distributed across the papers examined: qualitative (37.2%, quantitative (29.6%, and mixed methods (33.2%. However, there was an over-reliance on data collection from a single source in 83.9% of papers analysed, and this source was primarily students. There was some, but limited, evidence of the use of triangulation through the use of multiple data collection instruments (e.g. survey, assessment tasks, grade databases. Similarly, only one-third of publications classified as mixed methods integrated the analysis and interpretation of the qualitative and quantitative data equally within the study. We conclude that current SoTL research is characterised by methodological pluralism but could be advanced through inclusion of more diverse approaches, such as close reading, and adoption of strategies known to enhance the quality of research, for example, triangulation and visual representation.

    Full Text Available Local preparedness against earthquakes has been recently highlighted in research and policies on disaster management and risk reduction promotion in Iran. To advance the understanding of public preparedness and how it can be applied in diverse localities, further information is required about the predictors of people’s adoption of mitigation activities and earthquake preparedness. A synthesis of the available published research results on earthquake preparedness and the influencing factors in Iran are presented in this literature review. It emphasizes the complexity of both the concept of preparedness and the contextual factors that mediate its adoption. The predominant roles of public awareness, trusted information resources, social capital and community collaboration as predictors are discussed.

    The trafficking of persons around the world is a serious violation of human rights and manifestation of social injustice. It disproportionately affects women and children worldwide. Given the values of the social work profession and the prevalence of trafficking, it is essential to understand the current literature on human trafficking in social work journals. Using the PRISMA method, this systematic review (n = 94 articles) of human trafficking in social work journals found the following: more focus on sex trafficking than other forms of trafficking; a lack of a clear conceptualization and definition on the entire spectrum of trafficking; a lack of evidence-informed empirical research to inform programs, practice, and policy; and a dearth of recommendations for social work education. Specific implications for social work policy, research, practice, and education are highlighted and discussed.

    The main function of the rocket nozzle is to convert the enthalpy efficiency from combustion gas to kinetic energy and also to make high velocity out of the gas. The rocket nozzle usually consists of a converging and diverging part. With a smaller area on the neck and enlarged at the exit area. The velocity flow through the nozzle enlarges into the speed of sound through the neck and then becomes super sonic in the divergent part. Nozzle making or machining using conventional lathes, first performed is drilling on a massive metal that is bonded to the veneer, then after a sufficient gap is done deep-boring. At the time of the process of lathe in the nozzle RX 450 there is an obstacle that is vibrating tool holder chisel or holder so it is worried about not precision of the process of lathe. This should not happen because it can cause failure in the latter for it needs to be studied and studied further so that the lathe process goes accordingly. The holder material of ST 60 with a modulus of elasticity 200 GPa and a nozzle material of AISI 4340 alloy steel with σyield = 470 MPa, Shear Modulus G = 80 GPa. The purpose of this research is to observe the amplitude of vibration on the holder due to RX- 450 nozzle lathe processing for the purpose of amplitude that occurs in accordance with the desired so that the nozzle structure is no damage process. The result of the research was obtained holder with length (L) 80cm, profile width (B) 5 cm, height of profile (H) 10 cm, turning machine ω = 8.98 rad / sec and natural holder frequency ωn = 89.8 rad / second, Amplitude of vibration of δ = 1.21 mm, while the amplitude of the design X = 1.22 mm From the results of this study it can be said that the holder of a chisel or holder can be used as a tool at the time of RX nozzle retrieval process and is quite safe because it works under the condition ω/ω n Rocket Payload "AKPV Engineering University of Wyoming 2009 )

    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.

    This study systematically located and appraised peer-reviewed evidence for the efficacy of strategies to increase organ donation decision communication among adults including an assessment of study quality to guide future research in this field. There is little room to move in strengthening unanimously positive public attitudes toward organ donation. Consequently, researchers have called for a focus on organ donation decision communication to understand modifiable factors to increase organ donation rates. Multiple databases were searched during September 2015, and 44 studies were selected for inclusion. Data concerning participants, design, and outcomes were extracted. Studies were rated for quality and levels of evidence. Although not amenable to meta-analysis, the literature indicates that approximately 50% of adults who are willing to become an organ donor have discussed this decision with family. The majority of research was conducted in a Western context with an overrepresentation of students. Strategies to increase communication include education, motivation, input from lived experience, efforts to address salient audience beliefs, and scheduled reminders or prompts. Intentions and willingness to discuss organ donation were consistently positively related to discussion behavior; however, formative research and experimental studies testing theoretically driven interventions were scarce. There is mixed evidence for the role of demographic and attitudinal characteristics in the success of organ donation communication interventions. Additional theoretically based research is recommended to establish boundary conditions and validate strategies to increase organ donation decision communication among adults.

    Full Text Available AIM: Water quality has been the subject of many recent studies, moreover, the physical, chemical and biological parameters of water are used to investigate water quality and can be combined into a single index, the Water Quality Index (WQI, for use by water resource managers and the general public. The aim of this study was to use scientometrics to evaluate how water quality has been addressed in the international scientific literature. METHOD: For the quantitative analysis of the publications on WQI, we used the search database SCOPUS (http://www.scopus.com. The search was performed using the words "QUALIT* WATER* INDEX*" in papers published in all databases (through 2011. RESULTS: We found 554 articles that dealt with the use of WQI the number of publications has increased significantly over the last 20 years. India had the most studies, with 177 articles, followed by China, Brazil and the United States. These four countries together published 57% of studies on WQI. We generated 15 linear models to explain the number of publication by study sit (country. According to the Akaike Information Criterion (AIC, the best model to explain the number of publications by country was the model that combined Sanitation and Public Supply. CONCLUSION: Finally, this paper presents the state of scientific literature on WQI and demonstrates the growing interest of the scientific community in this issue, which is certainly due to the importance of the quantity and quality of water for human supply, economics, health and the conservation of water resources.

    Malaria research can play a vital role in addressing the malaria burden in Malawi. An organized approach in addressing malaria in Malawi started in 1984 by the establishment of the first National Malaria Control Programme and research was recognized to be significant. This study aimed to assess the type and amount of malaria research conducted in Malawi from 1984 to 2016 and its related source of funding. A systematic literature search was conducted in the Medline/PubMed database for Malawian publications and approved malaria studies from two Ethical Committees were examined. Bibliometric analysis was utilized to capture the affiliations of first and senior/last authors, funding acknowledgements, while titles, abstracts and accessed full text were examined for research type. A total of 483 publications and 165 approved studies were analysed. Clinical and basic research in the fields of malaria in pregnancy 105 (21.5%), severe malaria 97 (20.1%) and vector and/or agent dynamics 69 (14.3%) dominated in the publications while morbidity 33 (20%), severe malaria 28 (17%) and Health Policy and Systems Research 24 (14.5%) dominated in the approved studies. In the publications, 146 (30%) first authors and 100 (21%) senior authors, and 88 (53.3%) principal investigators in approved studies were affiliated to Malawian-based institutions. Most researchers were affiliated to the Malawi-Liverpool Wellcome Trust, College of Medicine, Blantyre Malaria Project, Ministry of Health, and Malaria Alert Centre. The major malaria research funders were the National Institute for Health/USA, Wellcome Trust and the US Agency for International Development. Only three (2.5%) out of 118 journals publishing research on malaria in Malawi were from Africa and the Malaria Journal, with 76 (15.7%) publications, published most of the research from Malawi, followed by the American Journal of Tropical Medicine and Hygiene with 57 (11.8%) in comparison to only 13 (2.7%) published in the local Malawi

    Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

    2016-11-01

    Full Text Available Background: Autosomal dominant congenital mirror movements (CMM is a neurodevelopmental disorder characterized by early onset involuntary movements of one side of the body that mirror intentional movements on the contralateral side; these persist throughout life in the absence of other neurological symptoms. The main culprit genes responsible for this condition are RAD51 and DCC. This condition has only been reported in a few families, and the molecular mechanisms linking RAD51 mutations and mirror movements (MM are poorly understood. Methods: We collected demographic, clinical, and genetic data of a new family with CMM due to a truncating mutation of RAD51. We reviewed the literature to identify all reported patients with CMM due to RAD51 mutations. Results: We identified a heterozygous nonsense mutation c.760C>T (p.Arg254∗ in eight subjects: four with obvious and disabling MM, and four with a mild phenotype. Including our new family, we identified 32 patients from 6 families with CMM linked to RAD51 variants. Discussion: Our findings further support the involvement of RAD51 in CMM pathogenesis. Possible molecular mechanisms involved in CMM pathogenesis are discussed.

    2016-01-01

    Background The delivery of radiotherapy (RT) involves the use of rather expensive resources and multi-disciplinary staff. As the number of cancer patients receiving RT increases, timely delivery becomes increasingly difficult due to the complexities related to, among others, variable patient inflow, complex patient routing, and the joint planning of multiple resources. Operations research (OR) methods have been successfully applied to solve many logistics problems through the development of a...

  7. A scoping research literature review to assess the state of existing evidence on the "bad" death.

    Wilson, Donna M; Hewitt, Jessica A

    2018-02-01

    A scoping research literature review on "bad death" was undertaken to assess the overall state of the science on this topic and to determine what evidence exists on how often bad deaths occur, what contributes to or causes a bad death, and what the outcomes and consequences of bad deaths are. A search for English-language research articles was conducted in late 2016, with 25 articles identified and all retained for examination, as is expected with scoping reviews. Only 3 of the 25 articles provided incidence information, specifying that 7.8 to 23% of deaths were bad and that bad deaths were more likely to occur in hospitals than in community-care settings. Many different factors were associated with bad deaths, with unrelieved pain being the most commonly identified. Half of the studies provided information on the possible consequences or outcomes of bad deaths, such as palliative care not being initiated, interpersonal and team conflict, and long-lasting negative community effects. This review identified a relatively small number of research articles that focused in whole or in part on bad deaths. Although the reasons why people consider a death to be bad may be highly individualized and yet also socioculturally based, unrelieved pain is a commonly held reason for bad deaths. Although bad and good deaths may have some opposing causative factors, this literature review revealed some salient bad death attributes, ones that could be avoided to prevent bad deaths from occurring. A routine assessment to allow planning so as to avoid bad deaths and enhance the probability of good deaths is suggested.

    Systematic review of the research evidence in veterinary homeopathy has never previously been carried out. This paper presents the search methods, together with categorised lists of retrieved records, that enable us to identify the literature that is acceptable for future systematic review of randomised controlled trials (RCTs) in veterinary homeopathy. All randomised and controlled trials of homeopathic intervention (prophylaxis and/or treatment of disease, in any species except man) were appraised according to pre-specified criteria. The following databases were systematically searched from their inception up to and including March 2011: AMED; Carstens-Stiftung Homeopathic Veterinary Clinical Research (HomVetCR) database; CINAHL; Cochrane Central Register of Controlled Trials; Embase; Hom-Inform; LILACS; PubMed; Science Citation Index; Scopus. One hundred and fifty records were retrieved; 38 satisfied the acceptance criteria (substantive report of a clinical treatment or prophylaxis trial in veterinary homeopathic medicine randomised and controlled and published in a peer-reviewed journal), and were thus eligible for future planned systematic review. Approximately half of the rejected records were theses. Seven species and 27 different species-specific medical conditions were represented in the 38 papers. Similar numbers of papers reported trials of treatment and prophylaxis (n=21 and n=17 respectively) and were controlled against placebo or other than placebo (n=18, n=20 respectively). Most research focused on non-individualised homeopathy (n=35 papers) compared with individualised homeopathy (n=3). The results provide a complete and clarified view of the RCT literature in veterinary homeopathy. We will systematically review the 38 substantive peer-reviewed journal articles under the main headings: treatment trials; prophylaxis trials. Copyright © 2012 The Faculty of Homeopathy.

    The number of publications in the field of medical education is still markedly low, despite recognition of the value of the discipline in the medical education literature, and exponential growth of publications in other fields. This necessitates raising awareness of the research methods and potential benefits of learning analytics (LA). The aim of this paper was to offer a methodological systemic review of empirical LA research in the field of medical education and a general overview of the common methods used in the field in general. Search was done in Medline database using the term "LA." Inclusion criteria included empirical original research articles investigating LA using qualitative, quantitative, or mixed methodologies. Articles were also required to be written in English, published in a scholarly peer-reviewed journal and have a dedicated section for methods and results. A Medline search resulted in only six articles fulfilling the inclusion criteria for this review. Most of the studies collected data about learners from learning management systems or online learning resources. Analysis used mostly quantitative methods including descriptive statistics, correlation tests, and regression models in two studies. Patterns of online behavior and usage of the digital resources as well as predicting achievement was the outcome most studies investigated. Research about LA in the field of medical education is still in infancy, with more questions than answers. The early studies are encouraging and showed that patterns of online learning can be easily revealed as well as predicting students' performance.

    The prevention of sexual assault (SA) in the U.S. military is a significant priority. This study applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to a literature search that identified research evaluating SA prevention programs conducted within military settings. Only six studies published between 2005 and 2016 met criteria for inclusion in the review. Studies demonstrated high heterogeneity in the: (1) conceptual framework of the prevention approach; (2) target population and timing of administration; (3) study recruitment methods; (4) methodological design; (5) method of delivery, program dosage and theory of change; and (6) outcome administration and efficacy. Scientific rigor according to the Oxford Center for Evidence-based Medicine was also variable. Several gaps in the research base were identified. Specifically, research evaluating SA prevention programs have only been conducted among U.S. Army and U.S. Navy samples. Most studies did not examine whether program participation was associated with reductions in rates of sexual violence. Studies also lacked utilization of a long-term follow-up period. Additionally, studies did not reflect the types of SA prevention programs currently being implemented in military settings. Taken together, further research is needed to enhance the evidence base for SA prevention in the military, and to evaluate the effectiveness of the approaches currently being conducted with service members.

    This report reviews 15 empirical studies of residential solar energy users and related literature on residential solar energy use. The purpose of the review is to summarize and analyze the experiences of residential solar users for helping formulate policies concerning the accelerated commercialization of solar technologies. Four of the studies employed case histories or focus group techniques. The 11 questionnaire studies represented interviews with over 1,600 owners of solar systems. The demographic characteristics of samples are listed and compared; research findings and conclusions are presented. Findings on user satisfaction and system performance, possible reasons for evidence of lacking correlation between them, and implications for consumer protection and future research are discussed. General findings are: (1) systematic research on the experiences of solar users is lacking - much research remains to be done; (2) the reported overall experiences of users has been very positive; (3) user reports indicate that system performance is generally good but there is some evidence that user reports are not accurate measures of actual performance; (4) a need exists for adequate consumer protection; (5) design or installation problems are evidenced in significant numbers of early solar installations; and (6) these problems evidently are resolvable. An annotated bibliography describes 10 other studies in progress.

    In general, late side effects after salvage radiotherapy (RT) for prostate cancer are below 10%. Patients with impaired DNA repair ability and genetic instability can have significantly increased reactions after RT. We present a patient who experienced severe side effects after additive RT for prostate cancer and died from the complications 25 months after RT. Imaging (MR) is shown as well as three-color fluorescence in situ hybridization. The blood sample testing revealed that radiosensitivity was increased by 35-55%. We undertook a review of the literature to give an overview over the tests established that are currently considered useful. This case highlights that the identification of patients with increased radiosensitivity is an important task in radiation protection. Groups of patients who should be screened have to be found and corresponding research facilities have to be set up. (orig.) [de

    Overviews of methods are potentially useful means to increase clarity and enhance collective understanding of specific methods topics that may be characterized by ambiguity, inconsistency, or a lack of comprehensiveness. This type of review represents a distinct literature synthesis method, although to date, its methodology remains relatively undeveloped despite several aspects that demand unique review procedures. The purpose of this paper is to initiate discussion about what a rigorous systematic approach to reviews of methods, referred to here as systematic methods overviews, might look like by providing tentative suggestions for approaching specific challenges likely to be encountered. The guidance offered here was derived from experience conducting a systematic methods overview on the topic of sampling in qualitative research. The guidance is organized into several principles that highlight specific objectives for this type of review given the common challenges that must be overcome to achieve them. Optional strategies for achieving each principle are also proposed, along with discussion of how they were successfully implemented in the overview on sampling. We describe seven paired principles and strategies that address the following aspects: delimiting the initial set of publications to consider, searching beyond standard bibliographic databases, searching without the availability of relevant metadata, selecting publications on purposeful conceptual grounds, defining concepts and other information to abstract iteratively, accounting for inconsistent terminology used to describe specific methods topics, and generating rigorous verifiable analytic interpretations. Since a broad aim in systematic methods overviews is to describe and interpret the relevant literature in qualitative terms, we suggest that iterative decision making at various stages of the review process, and a rigorous qualitative approach to analysis are necessary features of this review type

    Abstract Background There has been increasing interest in dementia care in recent years, including how practitioners, service providers and society in general can help individuals to live well with the condition. An important aspect to this is provision of advice to ensure conversation partners effectively support the person with dementia in conversation. Aims To provide a descriptive review of the literature examining everyday conversation in dementia in order to inform practice and research. Methods & Procedures This review used a method specifically developed for reviewing conversation analytic and related literature. A range of databases were searched using key words and explicitly described inclusion criteria leading to a final corpus of 50 titles. Using this qualitative methodology, each paper was examined and data extracted. The contribution of each of these is described and the implications for practice and research are outlined. Main Contribution This review examined studies into conversation in Alzheimer's disease, vascular dementia and Lewy body dementia, grouping these into: early influential studies; work drawing on positioning theory; studies using social and linguistic approaches; collaborative storytelling; formulaic language; studies specifically using conversation analysis; and conversation as a target for individualized therapy. In addition, more recent work examining primary progressive aphasia and behavioural variant frontotemporal dementia was explored. Overall, this review indicates that research examining conversation in natural settings provides a rich source of data to explore not just the challenges within conversation for those taking part, but also the skills retained by the person with dementia. An important aspect of this understanding is the notion that these skills relate not only to information exchange but also aspects of social interaction.

    Full Text Available Abstract Background The gap between research findings and clinical practice is well documented and a range of interventions has been developed to increase the implementation of research into clinical practice. Findings A review of systematic reviews of the effectiveness of interventions designed to increase the use of research in clinical practice. A search for relevant systematic reviews was conducted of Medline and the Cochrane Database of Reviews 1998-2009. 13 systematic reviews containing 313 primary studies were included. Four strategy types are identified: audit and feedback; computerised decision support; opinion leaders; and multifaceted interventions. Nine of the reviews reported on multifaceted interventions. This review highlights the small effects of single interventions such as audit and feedback, computerised decision support and opinion leaders. Systematic reviews of multifaceted interventions claim an improvement in effectiveness over single interventions, with effect sizes ranging from small to moderate. This review found that a number of published systematic reviews fail to state whether the recommended practice change is based on the best available research evidence. Conclusions This overview of systematic reviews updates the body of knowledge relating to the effectiveness of key mechanisms for improving clinical practice and service development. Multifaceted interventions are more likely to improve practice than single interventions such as audit and feedback. This review identified a small literature focusing explicitly on getting research evidence into clinical practice. It emphasizes the importance of ensuring that primary studies and systematic reviews are precise about the extent to which the reported interventions focus on changing practice based on research evidence (as opposed to other information codified in guidelines and education materials.

    Full Text Available Abstract The economy of China continues to boom and so have its biomedical research and related publishing activities. Several so-called neglected tropical diseases that are most common in the developing world are still rampant or even emerging in some parts of China. The purpose of this article is to document the significant research potential from the Chinese biomedical bibliographic databases. The research contributions from China in the epidemiology and control of schistosomiasis provide an excellent illustration. We searched two widely used databases, namely China National Knowledge Infrastructure (CNKI and VIP Information (VIP. Employing the keyword "Schistosoma" ( and covering the period 1990–2006, we obtained 10,244 hits in the CNKI database and 5,975 in VIP. We examined 10 Chinese biomedical journals that published the highest number of original research articles on schistosomiasis for issues including languages and open access. Although most of the journals are published in Chinese, English abstracts are usually available. Open access to full articles was available in China Tropical Medicine in 2005/2006 and is granted by the Chinese Journal of Parasitology and Parasitic Diseases since 2003; none of the other journals examined offered open access. We reviewed (i the discovery and development of antischistosomal drugs, (ii the progress made with molluscicides and (iii environmental management for schistosomiasis control in China over the past 20 years. In conclusion, significant research is published in the Chinese literature, which is relevant for local control measures and global scientific knowledge. Open access should be encouraged and language barriers removed so the wealth of Chinese research can be more fully appreciated by the scientific community.

    Many efforts have been made to create new diagnostic technologies for use in the diagnosis of central nervous system injury. However, there is still no consensus for the use of biomarkers in clinical acute spinal cord injury (SCI). The aims of this review are (1) to evaluate the current status of neurochemical biomarkers and (2) to discuss their potential acute diagnostic role in SCI by reviewing the literature. PubMed (http://www.ncbi.nlm.nih.gov/pubmed) was searched up to 2012 to identify publications concerning diagnostic biomarkers in SCI. To support more knowledge, we also checked secondary references in the primarily retrieved literature. Neurofilaments, cleaved-Tau, microtubule-associated protein 2, myelin basic protein, neuron-specific enolase, S100β, and glial fibrillary acidic protein were identified as structural protein biomarkers in SCI by this review process. We could not find reports relating ubiquitin C-terminal hydrolase-L1 and α-II spectrin breakdown products, which are widely researched in other central nervous system injuries. Therefore, we present our preliminary data relating to these two biomarkers. Some of biomarkers showed promising results for SCI diagnosis and outcome prediction; however, there were unresolved issues relating to accuracy and their accessibility. Currently, there still are not many reports focused on diagnostic biomarkers in SCI. This fact warranted the need for greater efforts to innovate sensitive and reliable biomarkers for SCI.

    In this paper, we conduct research on the memory ethics and thought transformation pattern and the applications on contemporary literature. Compared to scientifi c thinking, historical thinking, the thinking process characterized by direct image of literary creation of system integration, literary creation process is a fi ction. Literary psychology studies have shown that the transmission of literature as a kind of aesthetic experience, is far from perfect memories of feature, but memory, association, imagination, illusion, such as the result of the comprehensive sports psychological function, is in the creation subject specifi c emotions and as under the guidance of the appearance of the restructuring, merger. From the discussion above we can see that whether it is a literary language of authenticity, or false judgment characteristics of literary language, explain the fact that in literary text is not has direct realistic context, but a self-reference words, and it is a virtual space of the empirical. In this paper, we discuss the related theory with modifi cation that is innovative.

  2. Precarious beginnings: Gendered risk discourses in psychiatric research literature about postpartum depression.

    Godderis, Rebecca

    2010-09-01

    The transition to motherhood in western society is particularly informed by risk-based scientific and medical discourses and, as a result, women are especially subject to rationalities and practices that are employed in the name of risk. The aim of this article is to examine the gendered risk discourses that are embedded in one aspect of medicalized mothering - the postpartum period. This article interrogates three key elements of the discursive construction of postpartum depression (PPD) in contemporary psychiatric research literature (approximately 1980-2007). Specifically, I examine how risk-based reasoning is incorporated into the concepts of the postpartum triad and the high-risk mother, and how arguments about why PPD is a 'significant social problem' create a tension between the rights of the mother and those of the child. By placing women in a position to manage certain types of risks related to the postpartum period, these discourses serve to responsibilize women and structure their subjectivities in gendered ways.This analysis contributes to a growing literature that investigates how assumptions about gender, race, class and sexuality are produced and re-produced through the notion of risk.

    2013-01-01

    The purpose of this paper is to review the literature on exposure technique approaches in Computed Radiography (CR) imaging as a means of radiation dose optimization in CR imaging. Specifically the review assessed three approaches: optimization of kVp; optimization of mAs; and optimization of the Exposure Indicator (EI) in practice. Only papers dating back to 2005 were described in this review. The major themes, patterns, and common findings from the literature reviewed showed that important features are related to radiation dose management strategies for digital radiography include identification of the EI as a dose control mechanism and as a “surrogate for dose management”. In addition the use of the EI has been viewed as an opportunity for dose optimization. Furthermore optimization research has focussed mainly on optimizing the kVp in CR imaging as a means of implementing the ALARA philosophy, and studies have concentrated on mainly chest imaging using different CR systems such as those commercially available from Fuji, Agfa, Kodak, and Konica-Minolta. These studies have produced “conflicting results”. In addition, a common pattern was the use of automatic exposure control (AEC) and the measurement of constant effective dose, and the use of a dose-area product (DAP) meter

    Kern, V D; Hock, B

    1993-09-01

    A complete review of the scientific literature on experiments involving fungi in space is presented. This review begins with balloon experiments around 1935 which carried fungal spores, rocket experiments in the 1950's and 60's, satellite and moon expeditions, long-time orbit experiments and Spacelab missions in the 1980's and 90's. All these missions were aimed at examining the influence of cosmic radiation and weightlessness on genetic, physiological, and morphogenetic processes. During the 2nd German Spacelab mission (D-2, April/May 1993), the experiment FUNGI provided the facilities to cultivate higher basidiomycetes over a period of 10 d in orbit, document gravimorphogenesis and chemically fix fruiting bodies under weightlessness for subsequent ultrastructural analysis. This review shows the necessity of space travel for research on the graviperception of higher fungi and demonstrates the novelty of the experiment FUNGI performed within the framework of the D-2 mission.

  9. Literature research concerning alternative methods for validation of criticality calculation systems

    2016-05-01

    Beside radiochemical analysis of irradiated fuel and critical experiments, which has become a well-established basis for the validation of depletion code and criticality codes respectively, also results of oscillation experiments or the operating conditions of power reactor and research reactors can provide useful information for the validation of the above mentioned codes. Based on a literature review the potential of the utilization of oscillation experiment measurements for the validation of criticality codes is estimated. It is found that the reactivity measurements for actinides and fission products within the CERES program on the reactors DIMPLE (Winfrith, UK) and MINERVE (Cadarache, France) can give a valuable addition to the commonly used critical experiments for criticality code validation. However, there are approaches but yet no generally satisfactory solution for integrating the reactivity measurements in a quantitative bias determination for the neutron multiplication factor of typical application cases including irradiated spent fuel outside reactor cores, calculated using common criticality codes.

    Giese, Martina

    2007-01-01

    German scholarly literature (Fachliteratur) of the middle ages devoted to falconry falls into two main categories: Translations, mostly of latin works, and original treatises. After a short survey of falconry in the past, this article will discuss the original treatises and the history of their analysis since the 19th century. In this context it will deal with the research of the following scholars: Joseph von Hammer-Purgstall, Anton von Perger, Ernst von Dombrowski, Hermann Werth, Christoph von Biedermann and--most importantly--Kurt Lindner. The appendix contains the editio princeps of the German Münchener Rezeptar I from the codex unicus, München, Universitätsbibliothek, 80 Cod. ms. 354, fol. 31r-33r (dating from the 15th century).

    Full Text Available Higher education institutions are investing increasing resources in order to achieve favourable perceptions among their stakeholders. However, image and reputation management is a complex issue and how stakeholders perceive universities does not always coincide with the image the latter wish to project. For this reason, in this article we address a review of the literature on higher education image and reputation to identify the main knowledge gaps and establish the research lines that merit deeper examination in the future. The gaps identified highlight the need to improve knowledge about the way perceptions (image and reputation of university institutions are shaped, pinpointing the dimensions or essential aspects that influence their formation and determining whether their degree of influence differs when considering the perspectives of different stakeholders or individuals from different geographical areas. Theoretical propositions related to the identified gaps have been set out.

    Full Text Available As technologies diversify and become embedded in everyday lives, the technologies we expose to animals, and the new technologies being developed for animals within the field of Animal Computer Interaction (ACI are increasing. As we approach seven years since the ACI manifesto, which grounded the field within Human Computer Interaction and Computer Science, this thematic literature review looks at the technologies developed for (non-human animals. Technologies that are analysed include tangible and physical, haptic and wearable, olfactory, screen technology and tracking systems. The conversation explores what exactly ACI is whilst questioning what it means to be animal by considering the impact and loop between machine and animal interactivity. The findings of this review are expected to form the first grounding foundation of ACI technologies informing future research in animal computing as well as suggesting future areas for exploration.

    Full Text Available This study characterizes the results of scientific research on the effect of adopting the International Financial Reporting Standards (IFRS that have been published in the most prestigious scientific journals in the field of accounting at the international level and it identifies avenues for further research. Based on the analysis of a set of 67 articles published by the accounting journals that make up the Social Sciences Citation Index (SSCI, published between 2000 and 2013, it is concluded that, as a general rule, IFRS adoption has a positive effect on information quality, the capital market, analysts' ability to predict, comparability, and information use. Nevertheless, this effect depends on some factors, such as country's characteristics (namely, the enforcement level and companies' characteristics. Sharing rules is not, by itself, enough to create a common business language, and management incentives and institutional factors play a major role in framing the characteristics of financial reporting. Finally, some gaps are identified in the literature and avenues for further research are introduced.

    Corvids (Corvidae) play a major role in ornithological research. Because of their worldwide distribution, diversity and adaptiveness, they have been studied extensively. The aim of the Corvids Literature Database (CLD, http://www.corvids.de/cld) is to record all publications (citation format) on all extant and extinct Crows, Ravens, Jays and Magpies worldwide and tag them with specific keywords making them available for researchers worldwide. The self-maintained project started in 2006 and today comprises 8000 articles, spanning almost 500 years. The CLD covers publications from 164 countries, written in 36 languages and published by 8026 authors in 1503 journals (plus books, theses and other publications). Forty-nine percent of all records are available online as full-text documents or deposited in the physical CLD archive. The CLD contains 442 original corvid descriptions. Here, we present a metadata assessment of articles recorded in the CLD including a gap analysis and prospects for future research. Database URL: http://www.corvids.de/cld PMID:26868053

    2017-11-01

    While growing evidence suggests that microfinance is an effective approach for improved women's health, a significant gap remains in our understanding. The objective of this review is to synthesise the findings from published literature focused on microfinance and health issues particularly affecting women, including HIV/AIDS, reproductive health, mental health, and violence. Forty-one articles that examine the impact of microfinance participation on women's health were identified through a systematic search of electronic databases, coded using a structured abstraction form, and synthesised. Review results indicate that the impact of microfinance on women's health is an area in great need of research and publication attention. Varied quality and reporting in the identified articles restricted the ability to draw concrete conclusions regarding the relationship between microfinance participation and women's health, but led to the identification of current gaps in existing published research. Future research should work to address the recommendations provided in order to offer additional evidence to better understand the use of microfinance programming as a structural intervention to improve women's health.

  16. Ecotoxicity of silver nanomaterials in the aquatic environment: a review of literature and gaps in nano-toxicological research.

    Walters, Chavon R; Pool, Edmund J; Somerset, Vernon S

    2014-01-01

    There has been extensive growth in nanoscale technology in the last few decades to such a degree that nanomaterials (NMs) have become a constituent in a wide range of commercial and domestic products. With NMs already in use in several consumer products, concerns have emerged regarding their potential adverse environmental impacts. Although research has been undertaken in order to minimise the gaps in our understanding of NMs in the environment, little is known about their bioavailability and toxicity in the aquatic environment. Nano-toxicology is defined as the study of the toxicity of nanomaterials. Nano-toxicology studies remain poorly and unevenly distributed. To date most of the research undertaken has been restricted to a narrow range of test species such as daphnids. Crabs are bio-indicators that can be used for toxicological research on NMs since they occupy a significant position in the aquatic food chain. In addition, they are often used in conventional ecotoxicological studies due to their high sensitivity to environmental stressors and are abundantly available. Because they are benthic organisms they are prone to contaminant uptake and bioaccumulation. To our knowledge the crab has never been used in nano-toxicological studies. In this context, an extensive review on published scientific literature on the ecotoxicity of silver NPs (AgNPs) on aquatic organisms was conducted. Some of the most common biomarkers used in ecotoxicological studies are described. Emphasis is placed on the use of biomarker responses in crabs as monitoring tools, as well as on its limitations. Additionally, the gaps in nano-toxicological research and recommendations for future research initiatives are addressed.

    Acute liver failure (ALF) is a medical emergency requiring immediate evaluation for liver transplantation. We describe an unusual case of a patient who presented with ascites, jaundice, and encephalopathy and was found to have ALF due to natural killer (NK)-like T cell leukemia/lymphoma. The key immunophenotype was CD2+, CD3+, CD7+, CD56+. This diagnosis, which was based on findings in the peripheral blood and ascitic fluid, was confirmed with liver biopsy, and was a contraindication to liver transplantation. A review of the literature shows that hematologic malignancies are an uncommon cause of fulminant hepatic failure, and that NK-like T-cell leukemia/lymphoma is a relatively recently recognized entity which is characteristically CD3+ and CD56+. This case demonstrates that liver biopsy is essential in diagnosing unusual causes of acute liver failure, and that infiltration of the liver with NK-like T-cell lymphoma/leukemia can cause acute liver failure.

    Full Text Available We report a case of a 90-year-old patient with intractable posterior epistaxis presenting as the only symptom of a nontraumatic low-flow carotid-cavernous sinus fistula. Purpose of this case report is to introduce low-flow carotid-cavernous sinus fistula in the differential diagnosis of intractable posterior epistaxis. We provide a literature review for the sequence of actions for the confrontation of posterior epistaxis. We also emphasize the significance of the radiological diagnostic and therapeutic procedures in the management of posterior epistaxis due to pathology of the cavernous sinus. The gold-standard diagnostic procedure of carotid-cavernous sinus fistula is digital subtraction angiography (DSA. DSA with coils is also the state-of-the-art therapy. By failure of DSA, neurosurgery or stereotactic radiosurgery (SRS may be used as alternatives. SRS may also be used as enhancement procedure of the DSA. Considering the prognosis of a successfully closed carotid-cavernous sinus fistula, recanalization occurs only in a minority of patients. Close follow-up is advised.

(1) Type of literature; (2) annual publication output; (3) distribution according to journals; (4) distribution according to country; (5) distribution according to institution; (6) top cited authors over the last 10 years; (7) projects financially supported by the NIH; and (8) clinical trials registered. (1) In all, 802 studies on MDSCs appeared in the Web of Science from 2002 to 2011, almost half of which derived from American authors and institutes. The number of studies on MDSCs has gradually increased over the past 10 years. Most papers on MDSCs appeared in journals with a particular focus on cell biology research, such as Experimental Cell Research, Journal of Cell Science, and PLoS One. (2) Eight MDSC research projects have received over US$6 billion in funding from the NIH. The current project led by Dr. Johnny Huard of the University of Pittsburgh-"Muscle-Based Tissue Engineering to Improve Bone Healing"-is supported by the NIH. Dr. Huard has been the most productive and top-cited author in the field of gene therapy and adult stem cell research in the Web of Science over last 10 years. (3) On ClinicalTrials.gov, "Muscle Derived Cell Therapy for Bladder Exstrophy Epispadias Induced Incontinence" Phase 1 is registered and sponsored by Johns Hopkins University and has been led by Dr. John P. Gearhart since November 2009. From our analysis of the literature and research trends, we found that MDSCs may offer further benefits in regenerative medicine.

    2010-08-01

    Recent articles have advocated for the use of qualitative methods in environmental health research. Qualitative research uses nonnumeric data to understand people's opinions, motives, understanding, and beliefs about events or phenomena. In this analysis of the literature, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. A primary search on ISI Web of Knowledge/Web of Science for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Inclusion and exclusion criteria are described. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. Ninety-one articles met inclusion criteria. These articles were published in 58 different journals, with a maximum of eight for a single journal. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health, with most studies relying on one-on-one interviews. Details of the analyses were absent from a large number of studies. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. Qualitative data are published in traditionally quantitative environmental health studies to a limited extent. However, this analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.

    Full Text Available Purpose: Disassembly is an important process that distinguishes remanufacturing from conventional manufacturing. It is a unique process that becomes focus of investigation from many scholars. Yet, most scholars investigate disassembly from technical and operational standpoint that lack of strategic perspective. This paper attempts to fill this gap by looking at disassembly from a strategic perspective by considering organisational characteristics, process choices and product attributes. To be more specific, this paper has three objectives. First, to gain understanding what has been done, and what need to be done in the field of disassembly in remanufacturing. Second, to conduct a systematic literature review for identifying the factors affecting disassembly for remanufacturing. Third, to propose a new model of disassembly for remanufacturing and also to provide avenues for future research. Design/methodology/approach: This study used a systematic literature review method. A series of steps were undertaken during the review. The study was started with determining the purpose of the study, selecting appropriate keywords, and reducing the selected papers using a number of criteria. A deeper analysis was carried out on the final paper that meets the criteria for this review. Findings: There are two main findings of this study. First, a list of factors affecting disassembly in remanufacturing is identified. The factors can be categorised into three groups: organisational factors, process choices and product attributes. Second, using factors that have been identified, a new model of disassembly process for remanufacturing is developed. Current studies only consider disassembly as a physical activity to break down products into components. In the new model, disassembly is viewed as a process that converts into into output, which consist of a series of steps.

    Although music has been widely used in healthcare, there has been scant review of literature analyzing the use of music as an intervention in healthcare research. The purpose of this article was to provide a narrative review of the literature to explore how "music therapy" has been used in healthcare research to promote healing in adult populations. The following five questions were addressed: (a) In what populations and under what conditions has music intervention been studied? (b) What specific kinds of music have been used for study intervention? (c) How has the music intervention been operationalized? (d) What metrics have been used as outcome measures? (e) Have music interventions been effective? Articles were retrieved from several scientific databases (PubMed, CINAHL, and PsycINFO) using the following search parameters: MeSH search terms "music therapy" in the title field with the search limit to "adults 19 years and older," "humans," "clinical randomized controlled studies," and "English." A total of 33 clinical randomized controlled studies that met the search criteria were reviewed. (a) In the reviewed studies (studied articles), subjects with dementia were the most commonly studied population group, and the predominant aim of the study was to alleviate anxiety. (b) Employed music interventions may be categorized as one of two types: passive (receptive) and active. The passive (receptive) music intervention commonly involved subjects in a resting position listening to music, whereas the active music intervention is usually carried out in a group format in which subjects are actively involved in the music intervention. (c) Intervention frequency, dosing, and duration were highly variable across the reviewed studies. Very few studies described the intervention setting, which made evaluation of these studies difficult. Direct supervision seemed to be an influential factor for adherence. (d) Outcome measures in retrieved articles involved two types

In the new model, disassembly is viewed as a process that converts into into output, which consist of a series of steps.

    HIV prevention research has been fraught with ethical concerns since its inception. These concerns were highlighted during HIV vaccine research and have been elaborated in microbicide research. A host of unique ethical concerns pervade the microbicide research process from trial design to post-trial microbicide availability. Given the urgency of research and development in the face of the devastating HIV pandemic, these ethical concerns represent an enormous challenge for investigators, sponsors and Research Ethics Committees (RECs) both locally and internationally. Ethical concerns relating to safety in microbicide research are a major international concern. However, in the urgency to develop a medically efficacious microbicide, some of these concerns may not have been anticipated. In the risk-benefit assessment of research protocols, both medical and psycho-social risk must be considered. In this paper four main areas that have a potential for medical and/or psycho-social harm are examined. Male partner involvement is controversial in the setting of covert use of microbicides. However, given the long-term exposure of men to experimental products, this may be methodologically, ethically and legally important. Covert use of microbicides may impact negatively on relationship dynamics leading to psychosocial harm to varying extents. The unexpectedly high rates of pregnancy during clinical trials raise important methodological and ethical concerns. Enrollment of adolescents without parental consent generates ethical and legal concerns that must be carefully considered by RECs and trial sites. Finally, paradoxical outcomes in recent trials internationally have advanced the debate on the nature of informed consent and responsibility of researchers to participants who become HIV positive during or after trials. Phase 3 microbicide trials are an undisputed research and ethical priority in developing countries. However, such trials must be conducted with attention to both

    There is little agreement about what constitutes good death or successful dying. The authors conducted a literature search for published, English-language, peer-reviewed reports of qualitative and quantitative studies that provided a definition of a good death. Stakeholders in these articles included patients, prebereaved and bereaved family members, and healthcare providers (HCPs). Definitions found were categorized into core themes and subthemes, and the frequency of each theme was determined by stakeholder (patients, family, HCPs) perspectives. Thirty-six studies met eligibility criteria, with 50% of patient perspective articles including individuals over age 60 years. We identified 11 core themes of good death: preferences for a specific dying process, pain-free status, religiosity/spirituality, emotional well-being, life completion, treatment preferences, dignity, family, quality of life, relationship with HCP, and other. The top three themes across all stakeholder groups were preferences for dying process (94% of reports), pain-free status (81%), and emotional well-being (64%). However, some discrepancies among the respondent groups were noted in the core themes: Family perspectives included life completion (80%), quality of life (70%), dignity (70%), and presence of family (70%) more frequently than did patient perspectives regarding those items (35%-55% each). In contrast, religiosity/spirituality was reported somewhat more often in patient perspectives (65%) than in family perspectives (50%). Taking into account the limitations of the literature, further research is needed on the impact of divergent perspectives on end-of-life care. Dialogues among the stakeholders for each individual must occur to ensure a good death from the most critical viewpoint-the patient's. Copyright © 2016 American Association for Geriatric Psychiatry.

    Evidence suggests that disparities in adult immunization (AI) rates are growing. Providers need adequate patient resources and information about successful interventions to help them engage in effective practices to reduce AI disparities. The primary purposes of this paper were to review and summarize the evidence base regarding interventions to reduce AI disparities and to scan for relevant resources that could support providers in their AI efforts to specifically target disparities. First, building on a literature review conducted by the U.S. Centers for Disease Control and Prevention, we searched the peer-reviewed literature to identify articles that either discussed interventions to reduce AI disparities or provided reasons and associations for disparities. We scanned the articles and conducted an internet search to identify tools and resources to support efforts to improve AI rates. We limited both searches to resources that addressed influenza, pneumococcal, hepatitis B, Tdap, and/or herpes zoster vaccinations. We found that most articles characterized AI disparities, but several discussed strategies for reducing AI disparities, including practice-based changes, communication and health literacy approaches, and partnering with community-based organizations. The resources we identified were largely fact sheets and handouts for patients and journal articles for providers. Most resources pertain to influenza vaccination and Spanish was the most prevalent language after English. More evaluation is needed to assess the health literacy levels of the materials. We conclude that additional research is needed to identify effective ways to reduce AI disparities and more resources are needed to support providers in their efforts. We recommend identifying best practices of high performers, further reviewing the appropriateness and usefulness of available resources, and prioritizing which gaps should be addressed.

    Workplace health promotion may include approaches focusing on behavioral change among employees and approaches with a holistic system-oriented thinking aiming at changing the physical, social and organizational factors of a setting. This literature review aimed to identify studies on workplace health promotion in the Nordic countries (Denmark, Finland, Iceland, Norway and Sweden), to describe when, where and how the studies were performed and to further analyze the use of settings approaches and empowerment processes. Using scientific literature databases, we found 1809 hits when searching for Nordic studies published from 1986 to 2008 with the search term health promotion. Of these, 116 studies were related to workplace health promotion and 33 included interventions. We used content analysis to analyze the abstracts of all articles and the full articles of the intervention studies. Most studies were performed in Sweden and Finland. The focus was mainly on behavioral change rather than on holistic health promotion as defined by the Ottawa Charter for Health Promotion. This was especially obvious for the intervention studies. In addition to the intervention studies using non-settings approaches with top-down driven behavioral change, we identified studies with participatory settings approaches aimed at changing the setting. We categorized relatively few studies as having a non-participatory settings approach. The studies aiming specifically at improving employees' empowerment were evenly distributed between the categories market-oriented persuasion of empowerment, therapeutic empowerment and empowerment as a liberal management strategy. More studies on workplace health promotion using empowering and participatory settings approaches are needed in the Nordic countries, and a more theory-based approach towards this research field is needed.

    Primary liver cancer remains one of the most lethal malignancies worldwide. Due to differences in prevalence of etiological factors the incidence of primary liver cancer varies among the world, with a peak in East-Asia. As this disease is still lethal in most of the cases, research has to be done to improve our understanding of the disease, offering insights for possible treatment options. For this purpose, animal models are widely used, especially mouse models. In this review, we describe the different types of mouse models used in liver cancer research, with emphasis on genetically engineered mice used in this field. We focus on hepatocellular carcinoma (HCC), as this is by far the most common type of primary liver cancer, accounting for 70%-85% of cases. PMID:19058325

    The 2013-2016 Ebola outbreak in West Africa highlighted both the successes and limitations of social science contributions to emergency response operations. An important limitation was the rapid and effective communication of study findings. A systematic review was carried out to explore how rapid qualitative methods have been used during global heath emergencies to understand which methods are commonly used, how they are applied, and the difficulties faced by social science researchers in the field. We also asses their value and benefit for health emergencies. The review findings are used to propose recommendations for qualitative research in this context. Peer-reviewed articles and grey literature were identified through six online databases. An initial search was carried out in July 2016 and updated in February 2017. The PRISMA checklist was used to guide the reporting of methods and findings. The articles were assessed for quality using the MMAT and AACODS checklist. From an initial search yielding 1444 articles, 22 articles met the criteria for inclusion. Thirteen of the articles were qualitative studies and nine used a mixed-methods design. The purpose of the rapid studies included: the identification of causes of the outbreak, and assessment of infrastructure, control strategies, health needs and health facility use. The studies varied in duration (from 4 days to 1 month). The main limitations identified by the authors were: the low quality of the collected data, small sample sizes, and little time for cross-checking facts with other data sources to reduce bias. Rapid qualitative methods were seen as beneficial in highlighting context-specific issues that need to be addressed locally, population-level behaviors influencing health service use, and organizational challenges in response planning and implementation. Recommendations for carrying out rapid qualitative research in this context included the early designation of community leaders as a point of

    Full Text Available KEY POINTS➢ Studies suggest a substantial minority of healthy older adults have hallucinatory experiences, in line with existing evidence on hallucinations in other age groups, though it is still unclear if hallucination prevalence increases or declines with age in older cohorts.➢ Stigma attached to both hallucinations and ageing leads to considerable under-reporting of these experiences in healthy older adults and may negatively bias how professionals, family members, and the public respond.➢ Why and when hallucinations in healthy older adults remit, persist, or progress to other clinical disorders remains poorly understood.➢ Current evidence points to a range of factors associated with hallucinations in older adults including decline in sensory or cognitive functioning, poor sleep, and psychosocial stressors (e.g., social isolation, loneliness, and bereavement, highlighting the need for accurate assessment and tailored interventions.Hallucinations, though common in youth and younger adults, are not the preserve of these age groups. Accumulating evidence shows that hallucinatory experiences are also present at surprisingly high rates in healthy older adults in the general community. Furthermore, stigma and misunderstanding of hallucinations, together with ageism, may lead to under-reporting of these experiences by older adults, and misdiagnosis or mismanagement by health and mental health practitioners. Consequently, improved public and professional knowledge is needed about the nature and significance of hallucinations with advancing age. The purpose of this review is to provide a comprehensive overview, and critical analysis, of research on the prevalence, psychosocial, and neurobiological factors associated with hallucinations in people aged 60 years and over. To the best of our knowledge, this is the first review of its kind in the literature. The evidence supports a dynamic conceptualization of hallucinations, in which the

    2017-10-01

    Full Text Available Introduction: Endoscopic retrograde cholangiopancreatography (ERCP has been proven to be a safe and effective method for diagnosis and treatment of biliary and pancreatic disorders. Major complications of ERCP include pancreatitis, hemorrhage, cholangitis, and duodenal perforation. We report a third case in literature of pneumoperitoneum after ERCP due to rupture of intrahepatic bile ducts and Glisson’s capsule in a peripheral hepatic lesion. Case Report: A 50-year-old male with a history of metastatic pancreatic neuroendocrine tumor and who had a partially covered metallic stent placed in the biliary tree 1 year ago presented to the oncology clinic with fatigue, abdominal pain, and hypotension. He was planned for ERCP for possible cholangitis secondary to obstructed previously placed biliary stent. However, the duodenoscope could not be advanced to the level of the major papilla because of narrowed pylorus and severely strictured duodenal sweep. Forward-view gastroscope was then passed with careful manipulation to the severely narrowed second part of the duodenum where the previously placed metallic stent was visualized. Balloon sweeping of stenting was done. Cholangiography did not show any leak. Following the procedure, the patient underwent CT scan of the abdomen that showed pneumoperitoneum which was communicating with pneumobilia through a loculated air collection in necrotic hepatic metastasis perforating Glisson’s capsule. The patient was managed conservatively. Conclusion: In our case, pneumoperitoneum resulted from rupture of intrahepatic bile ducts and Glisson’s capsule in hepatic metastasis. This case emphasizes the need for close clinical and radiological observation of patients with hepatic masses (primary or metastatic subjected to ERCP.

    Poerio, Vincenzo

    2015-01-01

    Unlike most of the work-related stress research, which emphasizes how to manage stressors and maximize the psychological well-being, the present article focuses on one particular kind of stressor: the experience of conflict or interference between demands at work and responsibilities and commitments outside of the work setting, especially in respect offamily life and one's personal life. Referred to as "work-family conflict" or (more recently) "work-life conflict", this stressor has been demonstrated in research since the 1990s to exert a considerable impact on individuals' well-being along with other areas such as family functioning and even performance on the job. In contrast to the intra-role conflict, which refers to interference between roles within a single domain (e.g., the work context), work-family (or work-life) conflict is a form of inter-role interference which occurs when there is conflict across domains. In the 1980s and 1990s, research and writing in this area focused predominantly on work versus family, but in recent years the "non-work" component has been expanded to include other aspects of people's lives. For simplicity, we will refer to the two major spheres as the "work domain" (i.e., a person's paid employment) and the "life domain" (which comprises all other dimensions of life, including family, recreation, community activities and personal life). Although this classification is not entirely appropriate, it enables differentiation between the two spheres.

    From vocabulary learning to imitating sequences of motor actions, the ability to plan, represent, and recall a novel sequence of items in the correct order is fundamental for many verbal and nonverbal higher level cognitive activities. Here we review phenomena of serial order documented across the verbal, visual, and spatial short-term memory domains and interpret them with reference to the principles of serial order and ancillary assumptions instantiated in contemporary computational theories of memory for serial order. We propose that functional similarities across domains buttress the notion that verbal, visual, and spatial sequences are planned and controlled by a competitive queuing (CQ) mechanism in which items are simultaneously active in parallel and the strongest item is chosen for output. Within the verbal short-term memory CQ system, evidence suggests that serial order is represented via a primacy gradient, position marking, response suppression, and cumulative matching. Evidence further indicates that output interference operates during recall and that item similarity effects manifest during both serial order encoding and retrieval. By contrast, the principles underlying the representation of serial order in the visual and spatial CQ systems are unclear, largely because the relevant studies have yet to be performed. In the spatial domain, there is some evidence for a primacy gradient and position marking, whereas in the visual domain there is no direct evidence for either of the principles of serial order. We conclude by proposing some directions for future research designed to bridge this and other theoretical gaps in the literature.

  17. Magnetic anomalies of steel drums: a review of the literature and research results of the INGV

    2013-04-01

    Full Text Available The detection and evaluation of the status of disposal sites that contain hazardous waste materials is becoming an increasingly important element in environmental investigations. Close cooperation between the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Volcanology and Geophysics in Rome and the Italian environmental police has resulted in numerous underground investigations of different buried materials. Among the geophysical investigation tools, magnetometry is the most effective, rapid and precise of all of the geophysical methods for localizing buried steel drums. Analysis of magnetic map anomalies can provide a variety of information about buried materials, including extension, distribution and depth, with processing of the acquired magnetic data. This information is also very useful in case of excavations that are aimed at the recovery of hazardous waste. This study determines the most relevant analyses reported in the literature, with modeling of magnetometric methods for environmental applications both theoretically and experimentally. Some studies and research results achieved by the INGV in relation to magnetic anomalies produced by buried steel drums are also reported, as found in field operations and as achieved from test sites.

  18. Exploring an Unknown Territory: "Sleeping Beauties" in the Nursing Research Literature.

    Kokol, Peter; Blažun Vošner, Helena; Vermeulen, Joeri

    Sleeping Beauties (SBs) are publications that are scarcely cited in the years immediately following publication but then suddenly become highly cited later. Such publications have unique citation patterns and can reveal important developments in the field in which they appear. No holistic analysis of nursing SBs has been done yet. The aim of this study was to identify and analyze the SB phenomenon in the nursing research literature. The corpus for the nursing SB identification was harvested from the Web of Science Core Collection (Thomas Reuters) for the period 1934-2015. Citation histories of 212,239 publications were screened. From those, 3,209 publications with more than 100 citations were selected for analysis. We used our own software and applied the van Raan (2004) and Baumgartner (2010) criteria for SBs-a 5-year sleeping period with at most 10 citations during that time, an average of at least five citations per year after the first 10 years, with at least 100 citations in total. The knowledge context for SBs was determined using citing papers. All citing papers were analyzed with the help of VOSviewer software. Nine publications were identified as SBs (prevalence of 0.004%). The length of sleep duration ranged from 5 to 10 years (M = 6.8, SD = 2.0), depth of sleep ranged from 0.2 to 0.8 citations (M = 0.6, SD = 0.2), and awake intensity ranged from 6.4 to 15.0 citations (M = 11.0, SD = 3.8). The average number of citations to SBs was 229. Most nursing SBs were produced in the United States (n = 8) from top institutions in journals with high-impact factors. Nursing SBs covered topics including resilience, sampling in qualitative research, metasynthesis, postoperative pain in children, dementia rating scales, care of patients with Alzheimer's disease, nursing theory related to fatigue mechanisms in cancer patients, and family participation during resuscitation. Nursing SBs were cited by authors from a large number of institutions and countries; the number of

    2008-01-01

    Full Text Available Breast cancer is one of the most prevalent forms of cancer in the US. It is estimated that more than 180,000 American women will be diagnosed with invasive breast cancer in 2008. Fortunately, the survival rate is relatively high and continually increasing due to improved detection techniques and treatment methods. However, maintaining quality of life is a factor often under emphasized for breast cancer survivors. Breast cancer treatments are invasive and can lead to deformation of the breast. Breast reconstruction is important for restoring the survivor’s appearance. However, more work is needed to develop technologies for quantifying surgical outcomes and understanding women’s perceptions of changes in their appearance. A method for objectively measuring breast anatomy is needed in order to help both the breast cancer survivors and their surgeons take expected changes to the survivor’s appearance into account when considering various treatment options. In the future, augmented reality tools could help surgeons reconstruct a survivor’s breasts to match her preferences as much as possible.

    Health policy and systems research (HPSR) is increasingly funded and undertaken as part of health system strengthening efforts worldwide. HPSR ethics is also a relatively new and emerging field, with numerous normative and descriptive questions that have largely not been considered. Normative questions include what ethical principles and values should guide HPSR. Descriptive questions include what ethical concerns arise when conducting HPSR. A small but growing body of scholarly work characterizes the various ethics issues inherent in HPSR. Towards informing the future development of ethics guidance for HPSR, a scoping review was undertaken to: (1) identify the range of ethics issues relevant to the conduct of HPSR-with a deliberate (though not exclusive) focus on low- and middle-income country settings and (2) describe existing guidance on key ethics issues relevant to HPSR. Using the Cochrane methods as a basis, the review identified formal and informal literature on HPSR ethics by searching the following databases: PubMed's Medline, Embase, Global Health, Scopus, WHO Global Health Regional Libraries, LILACs, OpenDOAR and Bielefeld Academic Search Engine. In total, 11 062 documents were identified from the formal (10 519) and informal (543) literature. One hundred and seven of these documents (formal 99 and informal 8) met at least one inclusion criterion and underwent thematic analysis. Ethical issues in four main categories were identified: upholding autonomy, identifying and balancing risks and benefits, justice and determination of ethical review requirements. The review indicated that the ethical values behind HPSR place an emphasis on its contributing to the reduction of health disparities. Unsurprisingly then, numerous ethical concerns relating to justice arise in HPSR. However, the majority of existing guidance focuses on obtaining or waiving informed consent and, thus, appears to be insufficient for HPSR. A list of priority ethics issues in HPSR in

    In general, late side effects after salvage radiotherapy (RT) for prostate cancer are below 10%. Patients with impaired DNA repair ability and genetic instability can have significantly increased reactions after RT. We present a patient who experienced severe side effects after additive RT for prostate cancer and died from the complications 25 months after RT. Imaging (MR) is shown as well as three-color fluorescence in situ hybridization. The blood sample testing revealed that radiosensitivity was increased by 35-55%. We undertook a review of the literature to give an overview over the tests established that are currently considered useful. This case highlights that the identification of patients with increased radiosensitivity is an important task in radiation protection. Groups of patients who should be screened have to be found and corresponding research facilities have to be set up. (orig.)

    Side effects influence the acceptability and continuation of hormonal contraceptives. Counseling the client about the management of side effects is a principal approach advocated for increasing continuation. Evidence of a biological basis for variation in women's tolerance of hormonal contraceptives argues, however, that greater attention should be given to altering the product rather than principally attempting to alter a woman's ability to deal with the product. Discontinuation rates for hormonal contraceptives, largely attributable to side effects and health concerns, are high in nearly all less-developed countries for which Demographic and Health Survey data are available. Oral contraceptives appear to be particularly problematic for Latin American women, most notably in Bolivia. Clinical trials suggest substantial variation in the physiological response to exogenous hormones, and new evidence confirms the hypothesis that the normal hormonal profiles of Bolivian women are significantly lower than those of women in the United States. These findings suggest a need for more population-specific physiological research linked to analyses of the possible association between endogenous hormone differences and contraceptive continuation. Appropriately adjusting the level of the steroid delivered may benefit women's health and improve the acceptability and continuation of hormonal contraceptives.

    Within the sport shoe area torsion is described as the twisting and decoupling of the rear-, mid- and forefoot along the longitudinal axis of the foot. Studies have shown that running shoes restrict the torsion of the foot and thus they increase the pronation of the foot. Based on the findings, it is recommended to design running shoes, which allow the natural freedom of movement of the foot. The market introduction of the first torsion concept through adidas(R) took place in 1989. Independently of the first market introduction, only one epidemiological study was conducted in the running shoe area. The study should investigate the occurrence of Achilles tendon problems of the athletes running in the new "adidas Torsion(R) shoes". However, further studies quantifying the optimal region of torsionability concerning the reduction of injury incidence are still missing. Newer studies reveal that the criterion torsion only plays a secondary roll regarding the buying decision. Moreover, athletes are not able to perceive torsionability as a discrete functional parameter. It is to register, that several workgroups are dealing intensively with the detailed analysis of the foot movement based on kinematic multi-segment-models. However, scientific as well as popular scientific contributions display that the original idea of the torsion concept is still not completely understood. Hence, the "inverse" characteristic is postulated. The present literature review leads to the deduction that the functional characteristics of the torsion concept are not fully implemented within the running shoe area. This implies the necessity of scientific studies, which investigate the relevance of a functional torsion concept regarding injury prevention based on basic and applied research. Besides, biomechanical studies should analyse systematically the mechanism and the effects of torsion relevant technologies and systems.

    The Analytic Hierarchy Process (AHP), developed by Saaty in the late 1970s, is one of the methods for multi-criteria decision making. The AHP disaggregates a complex decision problem into different hierarchical levels. The weight for each criterion and alternative are judged in pairwise comparisons and priorities are calculated by the Eigenvector method. The slowly increasing application of the AHP was the motivation for this study to explore the current state of its methodology in the healthcare context. A systematic literature review was conducted by searching the Pubmed and Web of Science databases for articles with the following keywords in their titles or abstracts: "Analytic Hierarchy Process," "Analytical Hierarchy Process," "multi-criteria decision analysis," "multiple criteria decision," "stated preference," and "pairwise comparison." In addition, we developed reporting criteria to indicate whether the authors reported important aspects and evaluated the resulting studies' reporting. The systematic review resulted in 121 articles. The number of studies applying AHP has increased since 2005. Most studies were from Asia (almost 30%), followed by the US (25.6%). On average, the studies used 19.64 criteria throughout their hierarchical levels. Furthermore, we restricted a detailed analysis to those articles published within the last 5 years (n = 69). The mean of participants in these studies were 109, whereas we identified major differences in how the surveys were conducted. The evaluation of reporting showed that the mean of reported elements was about 6.75 out of 10. Thus, 12 out of 69 studies reported less than half of the criteria. The AHP has been applied inconsistently in healthcare research. A minority of studies described all the relevant aspects. Thus, the statements in this review may be biased, as they are restricted to the information available in the papers. Hence, further research is required to discover who should be interviewed and how, how

    Family caregiving is the crucial informal care resource to lessen the burdens associated with dementia. Research in this field has focused on reducing the caregiver's burden, but little attention has been given to promoting the positive aspects of caregiving. To conduct a systematic critical review of research on the nature of positive aspects of caregiving, and the factors predicting this phenomenon among family caregivers of dementia patients, with the ultimate purpose of gaining insights to explain how and why it emerges. A systematic search of the literature was undertaken in the databases OvidMedline, CINAHL, PsycINFO, Web of Science and Scopus, using the keywords 'care* AND Alzheimer OR dementia AND 'positive aspect' OR 'positive experience' OR 'positive perceptions' OR reward OR gain OR 'satisfaction with care*' OR 'care* satisfaction' OR benefit OR uplift OR meaning OR enjoyment OR pleasure OR growth OR hope OR gratification. The Critical Appraisal Skills Programme checklists for qualitative and cohort studies were used to evaluate data quality. Narrative data synthesis was undertaken using the five-stage Whittermore and Knafl method. A total of 3862 articles were identified, of which 41 were included in this review. The key findings are that positive aspects of caregiving among family caregivers of dementia patients form a multi-dimensional construct which covers four key domains: a sense of personal accomplishment and gratification, feelings of mutuality in a dyadic relationship, an increase of family cohesion and functionality, and a sense of personal growth and purpose in life. By integrating the findings about the nature and conditions predicting positive aspects of caregiving, the presence of three conditions was identified as promoting the emergence of such qualities i) personal and social affirmation of role fulfilment, ii) effective cognitive emotional regulation and iii) contexts which favour finding meaning in the caregiving process. The findings

    PubMed is a widely used database for scientists to find biomedical-related literature. Due to the complexity of the selected research subject and its interdisciplinary nature, as well as the exponential growth in the number of disparate pieces of biomedical literature, it is an overwhelming challenge for scientists to define the right search strategies and quickly locate all related information. Specialized subsets and groupings of controlled vocabularies, such as Medical Subject Headings (MeSH), can enhance information retrieval in specialized domains, such as stem cell research. There is a need to develop effective search strategies and convenient solutions for knowledge organization in stem cell research. The understanding of the interrelationships between these MeSH terms also facilitates the building of knowledge organization systems in related subject fields. This study collected empirical data for MeSH-related terms from stem cell literature and developed a novel approach that uses both automation and expert-selection to create a set of terms that supports enhanced retrieval. The selected MeSH terms were reconstructed into a classified thesaurus that can guide researchers towards a successful search and knowledge organization of stem cell literature. First, 4253 MeSH terms were harvested from a sample of 5527 stem cell related research papers from the PubMed database. Next, unrelated terms were filtered out based on term frequency and specificity. Precision and recall measures were used to help identify additional valuable terms, which were mostly non-MeSH terms. The study identified 15 terms that specifically referred to stem cell research for information retrieval, which would yield a higher precision (97.7 %) and recall (94.4 %) rates in comparison to other approaches. In addition, 128 root MeSH terms were selected to conduct knowledge organization of stem cell research in categories of anatomy, disease, and others. This study presented a novel strategy

    Although advocates and providers identify stigma as a major factor in confounding the recovery of people with SUDs, research on addiction stigma is lacking, especially when compared to the substantive literature examining the stigma of mental illness. A comprehensive review of the stigma literature that yielded empirically supported concepts and methods from the mental health arena was contrasted with the much smaller and mostly descriptive findings from the addiction field. In Part I of this two part paper (American Journal of Addictions, Vol 26, pages 59-66, this issue), constructs and methods from the mental health stigma literature were used to summarize research that seeks to understand the phenomena of addiction stigma. In Paper II, we use this summary, as well as the extensive literature on mental illness stigma change, to outline a research program to develop and evaluate strategies meant to diminish impact on public and self-stigma (eg, education and contact). The paper ends with recommendations for next steps in addiction stigma research. (Am J Addict 2017;26:67-74). © 2016 American Academy of Addiction Psychiatry.

    Full Text Available Insights from psychology and cognitive science have, as yet, barely entered hospital choice research. This conceptual article closes this gap by reviewing and conceptually framing the current literature on hospital choice and patient information behavior and by discussing which tools are needed to advance scientific methodology in the study of patient decision-making strategies in hospital choice. Specifically, we make a call for more experimental research in hospital choice in order to complement existing theories, methods, and tools. This article introduces computerized process-tracing tools in hospital choice research, and also outlines a hands-on example, to provide a basis for future research.

    In order to determine which areas of cancer screening are currently receiving greatest emphasis in different parts of the world a Medline search of the literature for the period 2000-2002 was performed, concentrating attention on research into all aspects of efforts for early detection of tumours, with especial attention to methodology, motivation (including awareness of utility in the general populace and in minority groups), and intervention (professional training and general education). Focus on the skin, lung, cervix, breast, ovary + endometrium, oral cavity-oesophagus, gastric, colorectal, kidney + urinary tract and prostate, demonstrated large numbers of journals to be publishing papers in the field, with 10, 33, 130, 53, 24, 21, 6, 81, 12 and 58, respectively, in the period investigated, the grand total being 259. The average numbers of papers/journal ranged from 1.0-2.4 with only 15-35% appearing in journals with wide coverage. With the exception of oral, oesophageal and gastric cancer screening, an approximately 50% contribution in all areas was made by scientists in the US, followed by Europe (31% overall,) Asia (11%) then Australasia, Central and South America and Africa (3%, 2% and 1%, respectively). Clear differences were evident with the organ regarding specific topics receiving attention, most publications concerning the lung, ovary and urological tract dealing with detection methods. With the cervix and colorectum this topic accounted for half of the papers with especial attention to the relative advantages of the PAP smear, HPV testing and direct visual acetic acid (DVA) in the one, and FOBT and endoscopy in the other. Another major focus was found to be minority attitudes to breast, prostate and cervical screening in the US, whereas only few papers were found dealing with practical intervention, targeting professionals or screenees to increase participation in screening programs. The present approach suggested a number of areas requiring more

    To summarize and then assess with a pilot study the use of published best practice recommendations for priority setting during management of multiple healthcare research projects, in a resource-constrained environment. Medical, economic, business, and operations literature was reviewed to summarize and develop a survey to assess best practices for managing multiple projects. Fifteen senior healthcare research project managers, directors, and faculty at an urban academic institution were surveyed to determine most commonly used priority rules, ranking of rules, characteristics of their projects, and availability of resources. Survey results were compared to literature recommendations to determine use of best practices. Seven priority-setting rules were identified for managing multiple projects. Recommendations on assigning priorities by project characteristics are presented. In the pilot study, a large majority of survey respondents follow best practice recommendations identified in the research literature. However, priority rules such as Most Total Successors (MTS) and Resource Scheduling Method (RSM) were used "very often" by half of the respondents when better performing priority rules were available. Through experience, project managers learn to manage multiple projects under resource constraints. Best practice literature can assist project managers in priority setting by recommending the most appropriate priority given resource constraints and project characteristics. There is room for improvement in managing multiple projects.

    2018-05-01

    Full Text Available Introduction: Eating behavior often becomes unhealthier during the transition from adolescence to young adulthood, but not much is known about the factors that drive this change. We assess the available evidence on this topic through a literature review and pay special attention to the research designs employed in the studies available as well as the modifiability of the factors investigated in previous research. Method: We systematically conducted a scoping review by searching literature published in or after 2000 in three databases that described one or more factors associated with eating behavior or changes in eating behavior during the transition from adolescence to adulthood in the general population. Our search identified eighteen articles meeting these inclusion criteria. The socio-ecological DONE (Determinants of Nutrition and Eating framework, a recently developed dynamic framework of factors shaping dietary behavior, was used to structure and categorize the factors identified. Results: Most factors identified in the literature were individual-level factors (67% such as food beliefs, time constraints, and taste preferences; on the other hand, interpersonal-level factors (e.g., social support, environmental-level factors (e.g., product characteristics and policy-level factors (e.g., market regulations have been reported on less extensively. Furthermore, most factors discussed in the literature have been classified in the DONE framework as not easily modifiable. Moreover, previous studies largely used static research designs and focused primarily on one specific population (US freshmen. Discussion: This systematic scoping review identified several gaps in the available literature that hinder insight into the drivers of eating behavior (change during the transition from adolescence to young adulthood. There is an urgent need for research on broader populations, employing dynamic repeated-measures designs, and taking modifiability of

  8. Parenthood, information and support on the internet. A literature review of research on parents and professionals online

    2009-05-01

    Full Text Available Abstract Background The aim of this article was to address questions on how parents use the internet to find information and support regarding children, health and family life. Another aim was to find out how professionals use the internet to provide support and information to parents. This was done by a literature review. Methods Articles were searched for in five databases with a search strategy called "building block" approach. Results The review showed that the majority of today's parents search for both information and social support on the internet. However, there are considerable differences due to gender, age and socio-economic differences. First time middle class mothers aged 30–35 are most active in looking up health and parent information on the internet. In the same time, several studies report diminishing class differences on parent web sites. An important reason to the increasing number of parents who turn to the internet for information and interaction has shown to be the weakened support many of today's parents experience from their own parents, relatives and friends. Professionals have recognized the parents' great interest for going online and offer both information and support on the net. Conclusion Many benefits are reported, for example the possibility to reach out to a wider audience and to increase access to organisations without an increase in costs. Other benefits include the possibility for parents to remain anonymous in their contacts with professionals and that parents' perceived need for information can be effectively met around the clock. Interventions for wider groups of parents, such as parent training on the net, are still very rare and more research is needed to evaluate different types of interventions on the net. However, most studies were empirical and lacked theoretical frameworks which leave questions on how we can more fully understand this phenomenon unanswered.

    2016-11-01

    This review identifies the prominent topics in the literature pertaining to the ethical, legal, and social issues (ELSI) raised by research investigating personalized genomic medicine (PGM). The abstracts of 953 articles extracted from scholarly databases and published during a 5-year period (2008-2012) were reviewed. A total of 299 articles met our research criteria and were organized thematically to assess the representation of ELSI issues for stakeholders, health specialties, journals, and empirical studies. ELSI analyses were published in both scientific and ethics journals. Investigational research comprised 45% of the literature reviewed (135 articles) and the remaining 55% (164 articles) comprised normative analyses. Traditional ELSI concerns dominated the discourse including discussions about disclosure of research results. In fact, there was a dramatic increase in the number of articles focused on the disclosure of research results and incidental findings to research participants. Few papers focused on particular disorders, the use of racial categories in research, international communities, or special populations (e.g., adolescents, elderly patients, or ethnic groups). Considering that strategies in personalized medicine increasingly target individuals' unique health conditions, environments, and ancestries, further analysis is needed on how ELSI scholarship can better serve the increasingly global, interdisciplinary, and diverse PGM research community. © 2016 John Wiley & Sons Ltd.

    2016-12-01

    The purpose of this study was to present a narrative review of the literature of musculoskeletal causes of adult hip pain, with special attention to history, physical examination, and diagnostic imaging. A narrative review of the English medical literature was performed by using the search terms "hip pain" AND "anterior," "lateral," and "posterior." Additionally, specific entities of hip pain or pain referral sources to the hip were searched for. We used the PubMed search engine through January 15, 2016. Musculoskeletal sources of adult hip pain can be divided into posterior, lateral, and anterior categories. For posterior hip pain, select considerations include lumbar spine and femoroacetabular joint referral, sacroiliac joint pathology, piriformis syndrome, and proximal hamstring tendinopathy. Gluteal tendinopathy and iliotibial band thickening are the most common causes of lateral hip pain. Anterior hip pain is further divided into causes that are intra-articular (ie, labral tear, osteoarthritis, osteonecrosis) and extra-articular (ie, snapping hip and inguinal disruption [athletic pubalgia]). Entrapment neuropathies and myofascial pain should also be considered in each compartment. A limited number of historical features and physical examination tests for evaluation of adult hip pain are supported by the literature and are discussed in this article. Depending on the clinical differential, the gamut of diagnostic imaging modalities recommended for accurate diagnosis include plain film radiography, computed tomography, magnetic resonance imaging, skeletal scintigraphy, and ultrasonography. The evaluation of adult hip pain is challenging. Clinicians should consider posterior, lateral, and anterior sources of pain while keeping in mind that these may overlap.

    The study of video games is expanding, and so is the debate regarding their possible positive and deleterious effects. As controversies continue, several researchers have expressed their concerns about substantial biases existing in the field, which might lead to the creation of a skewed picture, both in the professional and in the lay literature. However, no study has tried to examine this issue quantitatively. The objective of our study was to examine possible systematic biases in the literature, by analyzing the publication trends of the medical and life sciences literature regarding video games. We performed a complete and systematic PubMed search up to December 31, 2013. We assessed all 1927 articles deemed relevant for their attitude toward video games according to the focus, hypothesis, and authors' interpretation of the study results, using a 3-category outcome (positive, negative, and neutral). We assessed the prevalence of different attitudes for possible association with year of publication, location of researchers, academic discipline, methodological research, and centrality of the publishing journals. The attitude toward video games presented in publications varied by year of publication, location, academic discipline, and methodological research applied (Pimpact factor (Pvideo games. Readers, both lay and professional, should weigh these contextual variables when interpreting studies' results, in light of the possible bias they carry. The results also support a need for a more balanced, open-minded approach toward video games, as it is likely that this complex phenomenon carries novel opportunities as well as new hazards.

    2001-08-01

    The topic of this paper concerns the use of therapeutic activities with persons with Alzheimer's disease (AD). The purpose is to present a critique of the research on these activities, with an emphasis on methodology. ORGANIZING CONSTRUCT AND SCOPE: Nursing literature identifies a number of purposes for activities for persons with AD. Activities should be therapeutic, enhance quality of life, arrest mental decline, and generate and maintain self-esteem. Other purposes of activities for this population are to create immediate pleasure, re-establish dignity, provide meaningful tasks, restore roles, and enable friendships. Activities may be more important to the psychological state of well-being of persons with dementia than the general physical and social environments in which they live. The literature reviewed was identified with the use of computer data bases (Medline - 1991-March 2001; Cumulative Index of Nursing and Allied Health Literature (CINAHL) - 1991-March 2001; and PsychLit - 1988-March 1999). In addition, data bases of Science Citation Index and Social Science Citation Indexes as they appear in the computer base, Web of Science, were searched for 1992-2001. The time period for each search was determined by the manner in which the literature was grouped for inclusion in the particular database. Hand searches of 11 selected journals included the years 1993-2001. The search dates were selected to reflect the time period when the largest number of studies on activities and AD have appeared in the professional literature. We critique a total of 33 studies. While researchers have demonstrated interest in the use of activities with persons with AD, theoretical and methodological difficulties, unclear findings and gaps exist, including a lack of emphasis on gender, ethnic, racial or cultural differences. Sampling issues involving diagnosis and staging complicate the research on individuals with AD. Case studies, single subject experimental designs, and tightly

    2011-01-01

    African American women, including adolescents and adults, are disproportionately affected by the transmission of Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS). HIV/AID is a health disparity issue for African American females in comparison to other ethnic groups. According to data acquired from 33 states in 2005, 64% of women who have HIV/ AIDS are African American women. It is estimated that during 2001-2004, 61% of African Americans under the age of 25 had been living with HIV/AIDS. This article is an analytical review of the literature emphasizing sexual assertiveness of African American women and the gap that exists in research literature on this population. The multifaceted model of HIV risk posits that an interpersonal predictor of risky sexual behavior is sexual assertiveness. The critical themes extracted from a review of the literature reveal the following: (a) sexual assertiveness is related to HIV risk in women, (b) sexual assertiveness and sexual communication are related, and (c) women with low sexual assertiveness are at increased risk of HIV As a result of this comprehensive literature, future research studies need to use models in validating sexual assertiveness interventions in reducing the risk of HIV/AIDS in African American women. HIV/AIDs prevention interventions or future studies need to target reducing the risk factors of HIV/AIDS of African Americans focusing on gender and culture-specific strategies.

    Rott, G.; Boecker, F.

    2014-01-01

    Following the first case of a systemic air embolism due to percutaneous CT-guided lung biopsy in our clinic we analysed the literature regarding this matter in view of influence able or avoidable risk factors. A systematic review of literature reporting cases of systemic air embolism due to CT-guided lung biopsy was performed to find out whether prone positioning might be a risk factor regarding this issue. In addition, a technical note concerning coaxial biopsy practice is presented. Prone position seems to have relevance for the development and/or clinical manifestation of air embolism due to CT-guided lung biopsy and should be considered a risk factor, at least as far as lesions in the lower parts of the lung are concerned. Biopsies of small or cavitary lesions in coaxial technique should be performed using a hemo static valve.

    Surveying valuable and most recent information from internet, has become vital for researchers and scholars, because every day, thousands and perhaps millions of scientific works are brought out as digital resources which represented by internet and researchers can't ignore this great resource to find related documents for their literature search, which may not be found in any library. With regard to variety of documents presented on the internet, search engines are one of the most effective search tools for finding information. The aim of this study is to evaluate the three criteria, recall, preciseness and importance of the four search engines which are PubMed, Science Direct, Google Scholar and federated search of Iranian National Medical Digital Library in addiction (prevention and treatment) to select the most effective search engine for offering the best literature research. This research was a cross-sectional study by which four popular search engines in medical sciences were evaluated. To select keywords, medical subject heading (Mesh) was used. We entered given keywords in the search engines and after searching, 10 first entries were evaluated. Direct observation was used as a mean for data collection and they were analyzed by descriptive statistics (number, percent number and mean) and inferential statistics, One way analysis of variance (ANOVA) and post hoc Tukey in Spss. 15 statistical software. P Value search engines had different operations with regard to the evaluated criteria. Since P Value was 0.004 search engines. PubMed, Science Direct and Google Scholar were the best in recall, preciseness and importance respectively. As literature research is one of the most important stages of research, it's better for researchers, especially Substance-Related Disorders scholars to use different search engines with the best recall, preciseness and importance in that subject field to reach desirable results while searching and they don't depend on just one

    The goal of this article is to conduct an assessment of the peer-reviewed primary literature with study objectives to analyze Amazon.com 's Mechanical Turk (MTurk) as a research tool in a health services research and medical context. Searches of Google Scholar and PubMed databases were conducted in February 2017. We screened article titles and abstracts to identify relevant articles that compare data from MTurk samples in a health and medical context to another sample, expert opinion, or other gold standard. Full-text manuscript reviews were conducted for the 35 articles that met the study criteria. The vast majority of the studies supported the use of MTurk for a variety of academic purposes. The literature overwhelmingly concludes that MTurk is an efficient, reliable, cost-effective tool for generating sample responses that are largely comparable to those collected via more conventional means. Caveats include survey responses may not be generalizable to the US population.

    To perform a comparative quantitative and qualitative analysis of Chinese and non-Chinese medical ethics literature using systematic research and literature analysis in order to discern research trends in the area and provide baseline data as a reference for relevant decision making and further study. We retrieved articles using MeSH terms and keywords related to medical ethics in PubMed and CNKI, and then constructed a set of charts by applying word co-occurrence, The Pathfinder Networks algorithms, an included subject chart, a research field relationship chart, and strategy coordination charts. The total of number of papers retrieved from PubMed was six times that retrieved from CNKI. Outside China, medical ethics has been studied in eight fully shaped subject fields, including morals, ethical review, physician-patient relationships, clinical trials, euthanasia, ethics education, clinical ethics, and health policy. In contrast, medical ethics research in China is still confined to five subject fields: morals, physician-patient relations, medical ethics education, ethical review, and medical research. Medical ethics research outside China emphasizes the application of medical ethics to solve emerging problems in clinical and medical research. It is mainly centered on morals, ethical review, and physician-patient relations. By comparison, medical ethics research in China places greater emphasis on morals and medical education. In order to narrow this gap between China and other countries, we should broaden the research scope of medical ethics and add more applied research, such as ethical review and medical education. © 2012 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

  6. Health Education Research and Practice Literature on Hispanic Health Issues: Have We Lost Sight of the Largest Minority Population?

    Price, James H; Khubchandani, Jagdish

    2016-03-01

    Hispanics constitute the largest racial/ethnic minority population in the United States and are the fastest growing segment of the population. Knowledge about health needs and practices, effective health promotion programs, and health policy making for Hispanics has the potential to improve population health outcomes for this group. Continued research and practice literature will aid in accomplishing these objectives. However, little is known about the extent of health education-related literature available on Hispanic health issues. In this review, we analyzed research and practice publications in all health education-related journals to assess the volume of articles published on Hispanic health issues. We found that the portion of journal articles devoted to Hispanic health issues varied widely among the journals and that there was a very limited emphasis on Hispanic health-related issues. Journal editors and editorial board members may need to be more proactive in soliciting manuscripts on Hispanic health, and our practitioners may have to improve their professional skills and cultural competence in order to work with Hispanic populations to produce research and practice literature that is of adequate quantity and quality to help improve Hispanics' health. © 2016 Society for Public Health Education.

    2009-03-01

    Full Text Available Abstract Background Ataxia-Telangiectasia syndrome is characterized by progressive cerebellar dysfunction, conjuctival and cutaneous telangiectasias, severe immune deficiencies, premature aging and predisposition to cancer. Clinical and radiographic evaluation for malignancy in ataxia-telangiectasia patients is usually atypical, leading to delays in diagnosis. Case presentation We report the case of a 20 year old ataxia-telangiectasia patient with gastric adenocarcinoma that presented as complete gastric outlet obstruction. Conclusion A literature search of adenocarcinoma associated with ataxia-telangiectasia revealed 6 cases. All patients presented with non-specific gastrointestinal complaints suggestive of ulcer disease. Although there was no correlation between immunoglobulin levels and development of gastric adenocarcinoma, the presence of chronic gastritis and intestinal metaplasia seem to lead to the development of gastric adenocarcinoma. One should consider adenocarcinoma in any patient with ataxia-telangiectasia who presents with non-specific gastrointestinal complaints, since this can lead to earlier diagnosis.

  10. The use of Skype in analysis and training: a research and literature review.

    Science.gov (United States)

    Merchant, John

    2016-06-01

    Of recent years there has not only been an increasing use of Skype in analytic treatment, supervision and teaching, but also a number of writers have been endeavouring to assess its effectiveness. Whilst it is generally agreed that Skype can facilitate an analytic encounter where distance prohibits a face-to-face process, where continuity needs to be maintained and where analysands are in areas far from specialized centres, there is divergence in the literature as to whether analysis, as opposed to psychotherapy, can be successful using Skype. This paper reviews the literature and concludes that the essentials of a genuine analytic process are not necessarily precluded by Skype. One central reason is because there exists a cross-modal communication channel between the human senses (underpinned by audiovisual mirror neurons) in addition to the recently discovered instinct for communication and interpersonal understanding, and these can override the need for physical proximity of the participants. The essentials of an analytic frame can thus be maintained, and the continuity that Skype enables means that containment is also facilitated and this counters the negative aspects of shuttle analysis. The critical issues for the profession then become the professional development for practitioners in the use of Skype and suggestions are listed. © 2016, The Society of Analytical Psychology.

    Thirty-eight studies of energy conservation research opportunities are reviewed. The 38 studies chosen for review include many of the major efforts in the identification of energy conservation research and development (R and D) opportunities and provide a representative sample of the types of studies that have been performed. The sample includes studies that focus on specific energy use (e.g., auto transport), as well as studies that focus on specific types of research (e.g., materials science). The sample also includes studies that can be further contrasted in terms of long-term vs. short-term projects, evolutionary vs. revolutionary ideas, generic vs. process-specific activities, and technology base research vs. hardware development. Each of these perspectives contributes toward assuring coverage of the breadth of energy conservation R and D opportunities. In each review the technical or end-use focus is described, the research ideas identified in the study are listed, and a critical summary is given. The reviews also indicate whether the studies present end-use consumption data, estimate potential energy savings, estimate times to commercialization, summarize existing research programs, or describe the identification methodology. In Section 2.0 the various research studies are compared. In Section 3.0 the characteristics of an aggregate list of research ideas are discussed. The characteristics were collected from the research opportunities studies, which are included in Appendix A. Appendix A contains a compilation of energy conservation R and D opportunities arranged by energy end-use applications. Appendix B contains an outline of the format followed in writing the critical reviews of the studies, the individual study reviews, and the extended bibliography of 88 studies that describe energy conservation research opportunities.

    Greenhalgh, Trisha; Potts, Henry W W; Wong, Geoff; Bark, Pippa; Swinglehurst, Deborah

    2009-01-01

    Context: The extensive research literature on electronic patient records (EPRs) presents challenges to systematic reviewers because it covers multiple research traditions with different underlying philosophical assumptions and methodological approaches. Methods: Using the meta-narrative method and searching beyond the Medline-indexed literature, this review used “conflicting” findings to address higher-order questions about how researchers had differently conceptualized and studied the EPR and its implementation. Findings: Twenty-four previous systematic reviews and ninety-four further primary studies were considered. Key tensions in the literature centered on (1) the EPR (“container” or “itinerary”); (2) the EPR user (“information-processer” or “member of socio-technical network”); (3) organizational context (“the setting within which the EPR is implemented” or “the EPR-in-use”); (4) clinical work (“decision making” or “situated practice”); (5) the process of change (“the logic of determinism” or “the logic of opposition”); (6) implementation success (“objectively defined” or “socially negotiated”); and (7) complexity and scale (“the bigger the better” or “small is beautiful”). Conclusions: The findings suggest that EPR use will always require human input to recontextualize knowledge; that even though secondary work (audit, research, billing) may be made more efficient by the EPR, primary clinical work may be made less efficient; that paper may offer a unique degree of ecological flexibility; and that smaller EPR systems may sometimes be more efficient and effective than larger ones. We suggest an agenda for further research. PMID:20021585

    2014-10-01

    In recent years, more and more researchers in science education have been turning to the practice of combining qualitative and quantitative methods in the same study. This approach of using mixed methods creates possibilities to study the various issues that science educators encounter in more depth. In this content analysis, I evaluated 18 studies from science education journals as they relate to the definition, design, and overall practice of using mixed methods. I scrutinized a purposeful sample, derived from 3 journals (the International Journal of Science Education, the Journal of Research in Science Teaching, and the Research in Science Education) in terms of the type of data collected, timing, priority, design, the mixing of the 2 data strands in the studies, and the justifications authors provide for using mixed methods. Furthermore, the articles were evaluated in terms of how well they met contemporary definitions for mixed methods research. The studies varied considerably in the use and understanding of mixed methods. A systematic evaluation of the employment of mixed methods methodology was used to identify the studies that best reflected contemporary definitions. A comparison to earlier content analyses of mixed methods research indicates that researchers' knowledge of mixed methods methodology may be increasing. The use of this strategy in science education research calls, however, for an improved methodology, especially concerning the practice of mixing. Suggestions are given on how to best use this approach.

    1997-06-01

    The purpose of this study was to assess the quality of quantitative psychiatric/mental health nursing research articles published in English between 1982 and 1992, worldwide. Criteria for selection of articles included nurse authorship or co-authorship, use of a quantitative design and pertinence to an aspect of the nursing process with psychiatric/mental health patients. One hundred and ninety-four articles met these criteria. The quality of each article was assessed by two nurse experts using Duffy's Research Appraisal Checklist (RAC). Forty-six point nine per cent of the articles were rated as superior, 50% as average and 3.1% as below average. Other findings identified journals that published research articles, countries in which research was completed, applicability of funding and qualifications of the authors. The major implications of this study are that nurses can be directed to superior articles; more publication of research by nurse authors is warranted, research is being completed with little financial support, highly rated research publications tend to get funding and editorial policies affect the quality of publication.

    A new programme of systematic reviews of randomised controlled trials (RCTs) in homeopathy will distinguish important attributes of RCT records, including: placebo controlled versus other-than-placebo (OTP) controlled; individualised versus non-individualised homeopathy; peer-reviewed (PR) versus non peer-reviewed (NPR) sources. (a) To outline the methods used to search and categorise the RCT literature; (b) to report details of the records retrieved; (c) to compare our retrieved records with those reported in two previous systematic reviews (Linde et al., 1997; Shang et al., 2005). Ten major electronic databases were searched for records published up to the end of 2011. A record was accepted for subsequent systematic review if it was a substantive report of a clinical trial of homeopathic treatment or prophylaxis in humans, randomised and controlled, and published in a PR or NPR journal. 489 records were potentially eligible: 226 were rejected as non-journal, minor or repeat publications, or lacking randomisation and/or controls and/or a 'homeopathic' intervention; 263 (164 PR, 99 NPR) were acceptable for systematic review. The 263 accepted records comprised 217 (137 PR, 80 NPR) placebo-controlled RCTs, of which 121 were included by, 66 were published after, and 30 were potentially eligible for, but not listed by, Linde or Shang. The 137 PR records of placebo-controlled RCTs comprise 41 on individualised homeopathy and 96 on non-individualised homeopathy. Our findings clarify the RCT literature in homeopathy. The 263 accepted journal papers will be the basis for our forthcoming programme of systematic reviews. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd. All rights reserved.

  7. Is research keeping up with changes in landscape policy? A review of the literature.

    Science.gov (United States)

    Conrad, Elisabeth; Christie, Mike; Fazey, Ioan

    2011-09-01

    Several innovative directions for landscape policy development and implementation have emerged over recent years. These include: (i) an expansion of scope to include all landscape aspects and landscape types, (ii) an increased emphasis on public participation, (iii) a focus on designing measures appropriate for different contexts and scales, and (iv) encouraging support for capacity-building. In this paper, we evaluate the extent to which these policy directions are reflected in the practice of academic landscape research. We evaluate all research papers published in three leading landscape journals over six years, as well as published research papers relating directly to the European Landscape Convention. The latter, which was adopted in 2000, establishes a framework for landscape protection, planning and management in Europe and is to date the only international legal instrument of its kind. Results indicate that whilst policy innovations do not appear to be a major stimulus for academic research, studies nevertheless address a range of landscape aspects, types and scales (albeit with a slight bias towards bio-physical landscape aspects). However, geographical representativeness of research is weak and dominated by the United States and northern/western Europe, and research capacity likewise appears to be unevenly distributed. Landscape research is also limited in the extent to which it involves stakeholders or develops innovative methods for doing so, notwithstanding that this remains a key challenge for policy-makers. Results point to the potential for landscape research to address areas (topical and geographical) which have received little attention to date, as well as suggesting mutual benefits of stronger links between policy and academia.

    Research into chiropractors' use of evidence in clinical practice appears limited to a single small qualitative study. The paucity of research in this area suggests that it is timely to undertake a more extensive study to build a more detailed understanding of the factors that influence chiropractors' adoption of evidence-based practice (EBP) principles. This study aimed to identify Australian chiropractors' attitudes and beliefs towards EBP in clinical practice, and also examine their use of research literature and clinical practice guidelines. We used an online questionnaire about attitudes, beliefs and behaviours towards the use of EBP in clinical practice that had been developed to survey physiotherapists and modified it to ensure that it was relevant to chiropractic practice. We endeavoured to survey all registered Australian chiropractors (n = 4378) via email invitation distributed by Australian chiropractic professional organisations and the Chiropractic Board of Australia. Logistic regression analyses were conducted to examine univariate associations between responses to items measuring attitudes and beliefs with items measuring: age; years since registration; attention to literature; and use of clinical practice guidelines. Questionnaires were returned by 584 respondents (response rate approximately 13%). The respondents' perceptions of EBP were generally positive: most agreed that the application of EBP is necessary (77.9%), literature and research findings are useful (80.2%), EBP helps them make decisions about patient care (66.5%), and expressed an interest in learning or improving EBP skills (74.9%). Almost half of the respondents (45.1%) read between two to five articles a month. Close to half of the respondents (44.7%) used literature in the process of clinical decision making two to five times each month. About half of the respondents (52.4%) agreed that they used clinical practice guidelines, and around half (54.4%) agreed that they were able

    In spite of increasing governmental and organizational efforts, organizations still struggle to improve the safety of their employees as evidenced by the yearly 2.3 million work-related deaths worldwide. Occupational safety research is scattered and inaccessible, especially for practitioners. Through systematically reviewing the safety literature, this study aims to provide a comprehensive overview of behavioral and circumstantial factors that endanger or support employee safety. A broad search on occupational safety literature using four online bibliographical databases yielded 27.527 articles. Through a systematic reviewing process 176 online articles were identified that met the inclusion criteria (e.g., original peer-reviewed research; conducted in selected high-risk industries; published between 1980-2016). Variables and the nature of their interrelationships (i.e., positive, negative, or nonsignificant) were extracted, and then grouped and classified through a process of bottom-up coding. The results indicate that safety outcomes and performance prevail as dependent research areas, dependent on variables related to management & colleagues, work(place) characteristics & circumstances, employee demographics, climate & culture, and external factors. Consensus was found for five variables related to safety outcomes and seven variables related to performance, while there is debate about 31 other relationships. Last, 21 variables related to safety outcomes and performance appear understudied. The majority of safety research has focused on addressing negative safety outcomes and performance through variables related to others within the organization, the work(place) itself, employee demographics, and-to a lesser extent-climate & culture and external factors. This systematic literature review provides both scientists and safety practitioners an overview of the (under)studied behavioral and circumstantial factors related to occupational safety behavior.

    The Nance-Horan syndrome is an X-linked disorder characterized by congenital cataract, facial features, microcornea, microphthalmia, and dental anomalies; most of the cases are due to NHS gene mutations on Xp22.13. Heterozygous carrier females generally present less severe features, and up to 30% of the affected males have intellectual disability. We describe two patients, mother and daughter, manifesting Nance-Horan syndrome. The cytogenetic and molecular analyses demonstrated a 46,X,t(X;1)(p22.13;q22) karyotype in each of them. No copy-number genomic imbalances were detected by high-density microarray analysis. The mother had a preferential inactivation of the normal X chromosome; expression analysis did not detect any mRNA isoform of NHS. This is the first report of Nance-Horan syndrome due to a skewed X chromosome inactivation resulting from a balanced translocation t(X;1) that disrupts the NHS gene expression, with important implications for clinical presentation and genetic counseling.

    Delayed encephalopathy due to carbon monoxide (CO) poisoning can even occur in patients with mild symptoms of acute CO poisoning. Some cases taking conventional hyperbaric oxygen (HBO) therapy or steroid-pulse therapy may be insufficient, and AchEI may be effective. We report two cases of delayed encephalopathy after acute CO poisoning involving two women aged 69 (Case 1) and 60 years (Case 2) whose cognitive function improved with acetylcholinesterase inhibitor (AchEI) treatment. Delayed encephalopathy occurred 25 and 35 days after acute CO poisoning in Case 1 and Case 2, respectively. Both patients demonstrated cognitive impairment, apathy, and hypokinesia on admission. Although hyperbaric oxygen therapy did not yield any significant improvements, cognitive dysfunction improved substantially. This was evidenced by an improved Mini-Mental State Examination score ffom 9 to 28 points in Case 1 and an improved Hasegawa's dementia rating scale score from 4 to 25 points in Case 2 after administration of an AchEI. In Case 1, we administered galantamine hydrobromide, which was related with improved white matter lesions initially detected on brain magnetic resonance imaging. However, in Case 2 white matter lesions persisted despite AchEI treatment. AchEI treatment may result in improved cognitive and frontal lobe function by increasing low acetylcholine concentrations in the hippocampus and frontal lobe caused by decreased nicotinic acetylcholine receptor levels in delayed encephalopathy after CO poisoning. Physicians should consider AchEIs for patients demonstrating delayed encephalopathy due to CO poisoning.

    Full Text Available The analysis of the data of the domestic and foreign literature regarding the dynamics of narcotization among children and adolescents is carried out. It has been established that at present the growth rates of the use of psychoactive substances by minors far outstrip those of the adult population. It is also determined that in most cases "adult" drug addiction is formed in a teenage environment and therefore adolescents are a group of high-risk narcotization. Besides, new types of additions are constantly added: non-opioid analgetics, antidepressants, pharmacy products based on medicinal plants with stimulating or sedative properties, new means of perfumery and household chemicals, volatile organic compounds, etc. In this regard, in the clinical picture of drug intoxication, new variations of affective, psycho-organic and psychosomatic effects and complications are noted. In recent years, synthetic cannabinoids has rapidly gained "popularity" among young people that are successfully promoted by marketers. They are the part of the so-called designer drugs, appearing in the markets in the form of bath salts, flavors, fertilizers for indoor plants and "smoking mixtures" - spices. The publications of domestic and foreign authors give a lot of evidence of the ability of these substances not only to cause a state of intoxication, alienation, relaxation, but also leads to dependence on them with severe consequences for the psyche and all organism as a whole. Thus, the powerful anthropogenic damaging effect of designer drugs demonstrates concrete signals of a threat to health, demography and the economy of the society as a result of their use by the population.

The seller agrees to any price (includ-ing zero customers are paying. For about ten years researchers empirically investigate customer reactions to and economic outcomes of this pricing method. The present paper distinguishes PWYW from other voluntary payment mechanisms and reviews 72 English- or German-speaking PWYW publications, which appeared between January 2006 and September 2016 and contain 97 independent empirical data sets. Prior PWYW research is structured with the help of a conceptual framework which incorporates payment procedure design, buyer, seller, focal sales object and market context characteristics as factors potentially influencing customer perceptions of the PWYW scheme and their behavioral reactions to PWYW offers. The review discusses both consistent key findings as well as contradictory results and derives recommendations for future empirical PWYW research efforts.

    Full Text Available Cultural ecosystem services constitute a growing field of research that is characterized by an increasing number of publications from various academic disciplines. We conducted a semiquantitative review of publications explicitly dealing with cultural ecosystem services. Our aims were: (1 to provide an overview of the current state of research, (2 to classify the diversity of research approaches by identifying clusters of publications that address cultural ecosystem services in similar ways, and (3 to highlight some important challenges for the future of cultural ecosystem services research. We reviewed 107 publications and extracted 20 attributes describing their type and content, including methods, scales, drivers of change, and trade-offs between services. Using a cluster analysis on a subset of attributes we identified five groups of publications: Group 1, conceptual focus, deals with theoretical issues; Group 2, descriptive reviews, consists mostly of desktop studies; Group 3, localized outcomes, deals with case studies coming from different disciplines; Group 4, social and participatory, deals mainly with assessing preferences and perceptions; and Group 5, economic assessments, provides economic valuations. Emerging themes in cultural ecosystem services research relate to improving methods for cultural ecosystem services valuation, studying cultural ecosystem services in the context of ecosystem service bundles, and more clearly articulating policy implications. Based on our findings, we conclude that: (1 cultural ecosystem services are well placed as a tool to bridge gaps between different academic disciplines and research communities, (2 capitalizing on the societal relevance of cultural ecosystem services could help address real-world problems, and (3 cultural ecosystem services have the potential to foster new conceptual links between alternative logics relating to a variety of social and ecological issues.

    Recently, the pharmaceutical manufacturing industry has been growing rapidly in many countries in the world, including in Arab countries. Pharmaceuticals reach aquatic environments and are prevalent at small concentrations in wastewater from the drug manufacturing industry and hospitals. Such presence also occurs in domestic wastewater and results from the disposal of unused and expired medicines. Therefore, the objective of this study was to analyze and compare the quantity and quality of publications made by researchers in Arab countries on pharmaceutical wastewater. To retrieve documents related to pharmaceutical wastewater, we used the Scopus database on November 21, 2015. All documents with terms related to pharmaceutical wastewater in the title or abstract were analysed. Results obtained from Arab countries were compared with those obtained from Turkey, Iran and Israel. Globally, a total of 6360 publications were retrieved while those from Arab countries, Iran, Turkey and Israel, were 179, 113, 96 and 54 publications respectively. The highest share of publications belonged to Kingdom of Saudi Arabia (KSA) with a total of 47 (26.2 %) publications, followed by Egypt (38; 21.2 %), Tunisia (17; 9.5 %) and Morocco (16; 8.9 %). The total number of citations was 1635, with a mean of 9.13 and a median (inter quartile range) of 3 (1.0-10.0). The study identified 87 (48.6 %) documents with 32 countries of international collaboration with Arab countries. It was noted that Arab researchers collaborated mainly with authors in Western Europe (54; 30.2 %), followed by authors from the Asiatic region (29; 16.2 %) and Northern America (15; 8.4 %). The most productive institution was King Saud University, KSA (13; 7.3 %), followed by the National Research Centre, Egypt (10; 7.3 %). This study showed that KSA has the largest share of productivity on pharmaceutical wastewater research. Bibliometric analysis demonstrated that research productivity, mainly from Arab

    Interest in the problem of method biases has a long history in the behavioral sciences. Despite this, a comprehensive summary of the potential sources of method biases and how to control for them does not exist. Therefore, the purpose of this article is to examine the extent to which method biases influence behavioral research results, identify potential sources of method biases, discuss the cognitive processes through which method biases influence responses to measures, evaluate the many different procedural and statistical techniques that can be used to control method biases, and provide recommendations for how to select appropriate procedural and statistical remedies for different types of research settings.

    Citation analysis has been neglected in suicidology. The present note applies a mixed-methods approach to both test and suggest hypotheses for the variation in article impact in the bereavement literature. One hundred three articles from three core suicidology journals met the criteria for inclusion in the investigation. Citations to the articles were obtained from the Web of Science. Predictor variables included structural characteristics of the author (e.g., gender) and the article itself (e.g., years since publication). A multivariate regression analysis determined that, controlling for the other variables, the most important predictor of citations was the review article (β = .461), followed by year of publication (β = -.414), the multiauthored article (β = .302), publication in Suicide and Life-Threatening Behavior (SLTB) (β = .161), and male gender (β = .156). The 12 most cited articles were published between 1979 and 2004 in SLTB. The majority of these papers was written by males, were U.S. authors, and had more than one author. Four of the most cited articles were reviews. The study concludes that structural characteristics of articles and authors explained 41% of the variance in citations. The qualitative analysis determined that review papers, and papers on characteristics of suicide bereavement and psychological autopsies have been most frequently cited. Replication studies are needed for other subfields of suicidology. © 2014 The American Association of Suicidology.

    Background. Prayer is commonly used among patients for health purposes. Therefore, this review focused on three main questions: (1) why do people turn to prayer in times of illness?, (2) what are the main topics of their prayers?, and (3) how do they pray? Method. We undertook a systematic review of the literature by searching the databases PubMed, Medline, and PsycINFO. The following inclusion criteria were used: (1) participants in the study were patients dealing with an illness, (2) the study examined the use of private rather than intercessory prayer, and (3) the content and purpose of prayer rather than its effects were investigated. Results. 16 articles were included in the final review. Participants suffered from a variety of chronic diseases, mostly cancer. Five main categories for the reasons and topics of prayer were found: (1) disease-centered prayer, (2) assurance-centered prayer, (3) God-centered prayer, (4) others-centered prayer, and (5) lamentations. Among these, disease-centered prayer was most common. Conclusions. Although most patients with chronic diseases do pray for relief from their physical and mental suffering, the intention of their prayers is not only for healing. Rather, prayer can be a resource that allows patients to positively transform the experience of their illness.

    Full Text Available Varicella-zoster virus (VZV meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

    A 26-year-old male bodybuilder was admitted to the surgical department of a Danish community hospital for hematemesis. During the clinical interview, he revealed that he had recently finished a course of anabolic steroids and erythropoietin. The patient also had a previous history of infections and chronic ulcers due to paraffin-oil injections in both upper arms one year before. Over the course of the next few hours, the patient developed signs of multi-organ dysfunction, including pancreatitis, hemorrhagic gastritis, nephropathy with temporary anuria, and respiratory insufficiency, and was transferred to the ICU. After manometric monitoring on the patient's upper arms proved difficult, invasive blood pressure monitoring was used and revealed that the patient was in a state of hypertensive crisis. This case of multi-organ dysfunction was possibly caused by multi-substance-induced hypercalcemia. © Georg Thieme Verlag KG Stuttgart · New York.

    Common complications of pelvic fractures include visceral injury, large-volume hemorrhage, genitourinary injury, rectal injury, and pulmonary embolism. On the other hand, traumatic hernia is a rare complication, especially in association with pelvic fractures. We report a case of bowel perforation due to traumatic hernia at a pelvic fracture site. A 65-year-old female was presented at our hospital for further examination and treatment of ileus. She was diagnosed with bowel perforation due to traumatic hernia at a pelvic fracture site, and an emergency operation was thus immediately performed. We performed segmental jejunum resection and constructed jejunostomy, and the iliac bone fracture was fixed with four pins. In the postoperative course, she received antibiotics and vasopressors for septic shock. However, there was no need for either a ventilator, dialysis or admission to the ICU. At seven days after the operation, a residual abscess was detected in the pouch of Douglas. We performed percutaneous drainage (Clavien-Dindo IIIa) and jejunostomy closedown 35 days after the first operation. The postoperative course was without complication, but she received rehabilitation until she was able to walk unaided. She was discharged 64 days after the first operation. The occurrence of traumatic hernia is rare, especially in association with pelvic fractures. Although its rarity, traumatic hernia follows a severe course. Thus, proper diagnosis and effective treatment are necessary. Surgeons treating patients with pelvic injuries should consider the possibility of any complications and perform a work-up examination in order to achieve an accurate diagnosis at an earlier time point.

    Homelessness among older people is a growing concern across Canada and is expected to rise with demographic change (Crane & Warnes, 2010; Culhane, Metraux, Byrne, Stino, & Bainbridge, 2013). Yet current knowledge, policies, and practices on homelessness largely focus on younger populations. Likewise, research and policies on aging typically overlook homelessness. Responses to homelessness among older people must address complex needs related to health, income security, and housing. Based on a comprehensive literature review, this article outlines the existing and needed research with regards to homelessness among older people. We clarify the intersections of aging and homelessness; review the relevant statistics, including estimated prevalence; discuss pathways and variations in experience; and identify gaps in knowledge. We conclude with a call for an inclusive research agenda that will help build policies and practices to reduce and ultimately to eliminate homelessness among older people in Canada.

    This article reviews the available quantitative research on psychosocial adjustment and mental health among children (age reintegration in CAAFAG. Abduction, age of conscription, exposure to violence, gender, and community stigma were associated with increased internalizing and externalizing mental health problems. Family acceptance, social support, and educational/economic opportunities were associated with improved psychosocial adjustment. Research on the social reintegration and psychosocial adjustment of former child soldiers is nascent. A number of gaps in the available literature warrant future study. Recommendations to bolster the evidence base on psychosocial adjustment in former child soldiers and other war-affected youth include more studies comprising longitudinal study designs, and validated cross-cultural instruments for assessing mental health, as well as more integrated community-based approaches to study design and research monitoring. © 2012 The Authors.

    We present an update of recent literature (since 2007) exploring the factor structure of posttraumatic stress disorder (PTSD) symptom measures. Research supporting a four-factor emotional numbing model and a four-factor dysphoria model is presented, with these models fitting better than all other models examined. Variables accounting for factor structure differences are reviewed, including PTSD query instructions, type of PTSD measure, extent of trauma exposure, ethnicity, and timing of administration. Methodological and statistical limitations with recent studies are presented. Finally, a research agenda and recommendations are offered to push this research area forward, including suggestions to validate PTSD’s factors against external measures of psychopathology, test moderators of factor structure, and examine heterogeneity of symptom presentations based on factor structure examination.

    Hematologic disease affects people of all ages worldwide. In the past decade, researchers have made great progress in the field of hematology. In the present study we compared the hematology research output from China and other countries (USA, Germany, UK, Japan and South Korea) over the past 10 years and 5 years. The related articles were extracted based on the PubMed database. We recorded the number of publications, clinical trials, randomized controlled trials, meta-analyses, case reports, reviews, citations, impact factors, articles in the top 10 journals and most published journals to assess the quantity and quality of research output in each region. A total of 120,641 hematology-related articles were published from 2004 to 2013. The USA accounted for 27.13% (32,732/120,641) of the publications, followed by Germany (7,479/120,641; 6.20%), Japan (6,347/120,641; 5.26%), the UK (5,453/120,641; 4.52%), China (2,924/120,641; 2.42%) and South Korea (1,413/120,641; 1.17%). The ranking for cumulative impact factors was as follows: USA; Germany; UK; Japan; China and South Korea. The median impact factors in the UK, USA, and Germany were higher than Japan, South Korea, and China. Interestingly, the median impact factors in the three Asia countries were similar both in 2004-2013 and 2009-2013. The UK had the highest percentage of publications in the top 25% of journals, while China lagged behind and ranked last. When comparing the number of articles in the top 10 journals, the results were similar to the IF findings. Germany had the highest number of average citations, while China had the lowest number of average citation. The status of hematology research output from the 6 countries in 2009-2013 had little difference from 2004-2013. Thus, the USA has had a dominant role in hematologic research in the past 10 years. Overall, the quality of publications in European countries was better than Asia countries. Although China has made considerable progress in hematology

    China, as a rapidly developing country with the largest population in the world, is playing an increasingly important role in diabetes research. There are >10,000 diabetes doctors who care for a large population of diabetic patients. The quantity and quality of research on diabetes from 3 major regions of China, including Mainland China (ML), Taiwan (TW), and Hong Kong (HK), is unknown. We aimed to analyze the contributions of each of these 3 regions to diabetes research.Articles on diabetes originating from ML, TW, and HK that were published from 2005 to 2014 were retrieved from the Web of Science. The quantity of articles, citations, article types, and articles published in high-impact journals were analyzed.A total of 9302 articles were retrieved from the 3 regions of China. There were 6775 from ML, 1993 from TW, and 534 from HK, with an increasing trend in publications from 2005 to 2014. After 2006, the number of publications from ML exceeded TW and HK. The largest total number of citations (48,296) was from ML. The highest mean citations, however, were from HK (15.90). PLoS One was the most popular journal in all 3 regions. The greatest number of RCTs, clinical trials, meta-analyses, and articles published in high-impact journals were from ML.There has been a significant increase in the number of articles published on diabetes research from China during the past 10 years. Most of the articles were published by authors in ML, and an increasing trend began in 2006. HK had the highest quality research output in terms of mean citations per article.

    Full Text Available Objectives. Existing findings on cancer patients' use of information sources were synthesized to 1 rank the most and least used information sources and the most helpful information sources and to 2 find the impact of patient demographics and situations on use of information sources. Method. . To synthesize results found across studies, a systematic review was conducted. Medline and CINAHL were searched to retrieve literature on cancer patients' information source use. The retrieved articles were carefully selected according to predetermined criteria, and several articles were eliminated in a systematic approach. Analysis. The twelve articles that met the criteria were systematically analysed by extracting data from articles and summarizing data for the purpose of synthesis to determine the meaning of findings on most used information sources, least used information sources, most helpful information sources, effect of patient characteristics on preference for an information source, and effect of patient situations on preference for an information source. Results. In descending order of use, health care professionals, medical pamphlets, and family and friends were most used information sources. Internet and support groups were least used. In descending order of helpfulness, books, health care professionals and medical pamphlets were found to be most helpful information sources. Younger patients used health care professionals and certain forms of written information sources more than older patients. Conclusion. . The systematic review shows that many areas of cancer patients' information source use have been either neglected or barely analysed. An in-depth understanding of cancer patients' use of information sources and the characteristics in information sources they consider to be helpful is important for developing successful interventions to better inform patients.

    2018-04-01

    Technology-facilitated sexual violence (TFSV) refers to a range of behaviors where digital technologies are used to facilitate both virtual and face-to-face sexually based harms. Such behaviors include online sexual harassment, gender- and sexuality-based harassment, cyberstalking, image-based sexual exploitation, and the use of a carriage service to coerce a victim into an unwanted sexual act. This article reviews the current state of knowledge on these different dimensions, drawing on existing empirical studies. While there is a growing body of research into technology-facilitated harms perpetrated against children and adolescents, there is a dearth of qualitative and quantitative research on TFSV against adults. Moreover, few of the existing studies provide reliable data on the nature, scope, and impacts of TFSV. Preliminary studies, however, indicate that some harms, much like sexual violence more broadly, may be predominantly gender-, sexuality-, and age-based, with young women being overrepresented as victims in some categories. This review collects the empirical evidence to date regarding the prevalence and gender-based nature of TFSV against adults and discusses the implications for policy and programs, as well as suggestions for future research.

    Full Text Available In recent years, the interdisciplinary research of supply chains and sustainability has received extensive, yet gradual, attention; when compared to the rapid economic growth of the service industry, however, sustainable supply chain management has not been systematically explored yet. It has not only great theoretical significance, but also positive practical significance to provide a framework for the operation of a sustainable service supply chain from a sustainable development point of view. Based on the triple bottom line (TBL, we have analyzed related sustainable supply chain management research between 2006 and 2015, reviewed papers involving two or three bottom lines as well, and then introduced some classical frameworks for manufacturing supply chain management and service supply chain management. Afterward, by analyzing the differences between the manufacturing and service industries, we propose a framework of sustainable service supply chain management (SSSCM. Based on the impacts of sustainable development TBL on service supply chain participants, we have finally made a framework for sustainable operation facing triads service supply chain and proposed a future research agenda.

    Qualitative research uses nonnumeric data to understand people's opinions, motives, understanding, and beliefs about events or phenomena. In this analysis, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. A primary search for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. This analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.

    Big data management for information centralization (i.e. making data of interest findable) and integration (i.e. making related data connectable) in health research is a defining challenge in biomedical informatics. While essential to create a foundation for knowledge discovery, optimized solutions to deliver high-quality and easy-to-use information resources are not thoroughly explored. In this review, we identify the gaps between current data management approaches and the need for new capacity to manage big data generated in advanced health research. Focusing on these unmet needs and well-recognized problems, we introduce state-of-the-art concepts, approaches and technologies for data management from computing academia and industry to explore improvement solutions. We explain the potential and significance of these advances for biomedical informatics. In addition, we discuss specific issues that have a great impact on technical solutions for developing the next generation of digital products (tools and data) to facilitate the raw-data-to-knowledge process in health research.

    Full Text Available Abstract Background The introduction of evidence-based programs and practices into healthcare settings has been the subject of an increasing amount of research in recent years. While a number of studies have examined initial implementation efforts, less research has been conducted to determine what happens beyond that point. There is increasing recognition that the extent to which new programs are sustained is influenced by many different factors and that more needs to be known about just what these factors are and how they interact. To understand the current state of the research literature on sustainability, our team took stock of what is currently known in this area and identified areas in which further research would be particularly helpful. This paper reviews the methods that have been used, the types of outcomes that have been measured and reported, findings from studies that reported long-term implementation outcomes, and factors that have been identified as potential influences on the sustained use of new practices, programs, or interventions. We conclude with recommendations and considerations for future research. Methods Two coders identified 125 studies on sustainability that met eligibility criteria. An initial coding scheme was developed based on constructs identified in previous literature on implementation. Additional codes were generated deductively. Related constructs among factors were identified by consensus and collapsed under the general categories. Studies that described the extent to which programs or innovations were sustained were also categorized and summarized. Results Although "sustainability" was the term most commonly used in the literature to refer to what happened after initial implementation, not all the studies that were reviewed actually presented working definitions of the term. Most study designs were retrospective and naturalistic. Approximately half of the studies relied on self-reports to assess

    Mora-Ripoll, Ramon

    2011-06-01

    Scientific research has shown that laughter may have both preventive and therapeutic values. Health-related benefits of laughter are mainly reported from spontaneous laughter interventional studies. While the human mind can make a distinction between simulated and spontaneous laughter, the human body cannot. Either way health-related outcomes are deemed to be produced. Simulated laughter is thus a relatively under-researched treatment modality with potential health benefits. The aim of this review was firstly to identify, critically evaluate and summarize the laughter literature; secondly to assess to which extent simulated laughter health-related benefits are currently sustained by empirical evidence; and lastly to provide recommendations and future directions for further research. A comprehensive laughter literature search was performed. A list of inclusion and exclusion criteria was identified. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown different physiological and psychological benefits. Adverse effects are very limited and laughter is practically lacking in counter-indications. Despite the limited number of publications, there is some evidence to suggest that simulated laughter has also some effects on certain aspects of health, though further well-designed research is warranted. Simulated laughter techniques can be easily implemented in traditional clinical settings for health and patient care. Their effective use for therapeutic purposes needs to be learned, practiced, and developed as any other medical strategy. Practical guidelines and further research are needed to help health care professionals (and others) implement laughter techniques in their health care portfolio. Copyright © 2011 Elsevier Ltd.

    A growing burden of gunshot injuries demands evidence-based ballistic trauma management. No comprehensive systematic overview of the current knowledge is available to date. This study aims to identify and analyze the most influential publications in the field of orthopedic ballistic trauma research. All databases available in the Thomson Reuters Web of Knowledge were searched to conduct this bibliometrical study. The most cited orthopedic ballistic trauma articles published between 1950 and 2015 were identified by use of a multi-step approach. Publications with ten citations and more were analyzed for citations, journal, authorship, geographic origin, area of research, anatomical site, study type, study category, and level of evidence. Citations of the 128 included studies ranged from 113 to 10. These were published in fifty different journals between 1953 and 2011. Most publications (n=106; 83%) originated from the USA, were retrospective (n=85; 66.4%), level IV studies (n=90; 70.3%), reported on spinal gunshot injuries (n=49; 38.33%) and were published between 1980 and 2000 (n=111; 86.7%). This bibliometric study provides the first comprehensive overview of influential publications in the field of orthopedic ballistic trauma research. More prospective studies and high-quality systematic reviews are needed. Centres with a high burden of gunshot injuries from the developing world need to share their experience in form of international publications, to provide a more comprehensive picture of the global gun-related orthopedic injury burden. bibliometric analysis: level III.

  1. Mesolevel as Object of Research in the Scientific Economic Literature of Contemporary Russia

    Directory of Open Access Journals (Sweden)

    Andrei I. Volynskii

    2017-09-01

    Full Text Available The idea of distinguishing the meso-level of economic analysis, filling the gap between macro and micro levels, is by no means new. It has not found a proper recognition and development in the work of representatives of the economic mainstream, but, on the contrary, steadily attracts the attention of the supporters of the heterodox directions of economic science. In this article, we propose a retrospective analysis of the development of the meso-level idea of economic analysis done by Russian economists. Three main directions of the development of the theory of mesoeconomic research are singled out: 1 a systematic approach: understanding the meso-level as a process of intra-industry interactions between economic agents with the goal of harmonizing the economic system; 2 Regional-spatial approach; 3 Theoretical approach of methodological institutionalism, developed within the framework of interdisciplinary intersections of economics and sociology. It is noted that the selected directions do not contradict and, on the contrary, complement each other. The development of the theory of mesoeconomics in the paradigm of the Kleiner-formula, which equates the object of mesoeconomics research with the space of formation of institutions and the institutions themselves, opens broad prospects for the development of the meso-level of economic analysis within the framework of institutional research. The practical need to separate the meso-level as a separate hierarchical stage of the economic structure, traditionally consisting of macro- and microlevels, is explained both by the need to expand the methodological tools of economic science and practical necessity, since it is assumed that meso-level is the space for the formation and consolidation of innovative solutions needed to ensure Growth.

    This article reviews empirical support for treatments targeting women sexually assaulted during adolescence or adulthood. Thirty-two articles were located using data from 20 separate samples. Of the 20 samples, 12 targeted victims with chronic symptoms, three focused on the acute period post-assault, two included women with chronic and acute symptoms, and three were secondary prevention programs. The majority of studies focus on posttraumatic stress disorder (PTSD), depression, and/or anxiety as treatment targets. Cognitive Processing Therapy and Prolonged Exposure have garnered the most support with this population. Stress Inoculation Training and Eye Movement Desensitization and Reprocessing also show some efficacy. Of the four studies that compared active treatments, few differences were found. Overall, cognitive behavioral interventions lead to better PTSD outcomes than supportive counseling does. However, even in the strongest treatments more than one-third of women retain a PTSD diagnosis at post-treatment or drop out of treatment. Discussion highlights the paucity of research in this area, methodological limitations of examined studies, generalizability of findings, and important directions for future research at various stages of trauma recovery.

    Objectives Comparison groups are essential for accurate testing and interpretation of yoga intervention trials. However, selecting proper comparison groups is difficult because yoga comprises a very heterogeneous set of practices and its mechanisms of effect have not been conclusively established. Methods We conducted a systematic review of the control and comparison groups used in published randomized controlled trials (RCTs) of yoga. Results We located 128 RCTs that met our inclusion criteria; of these, 65 included only a passive control and 63 included at least one active comparison group. Primary comparison groups were physical exercise (43%), relaxation/meditation (20%), and education (16%). Studies rarely provided a strong rationale for choice of comparison. Considering year of publication, the use of active controls in yoga research appears to be slowly increasing over time. Conclusions Given that yoga has been established as a potentially powerful intervention, future research should use active control groups. Further, care is needed to select comparison conditions that help to isolate the specific mechanisms of yoga’s effects. PMID:25440384

    2018-03-01

    Single-case research (SCR) has been a valuable methodology in special education research. Montrose Wolf (1978), an early pioneer in single-case methodology, coined the term "social validity" to refer to the social importance of the goals selected, the acceptability of procedures employed, and the effectiveness of the outcomes produced in applied investigations. Since 1978, many contributors to SCR have included social validity as a feature of their articles and several authors have examined the prevalence and role of social validity in SCR. We systematically reviewed all SCR published in six highly-ranked special education journals from 2005 to 2016 to establish the prevalence of social validity assessments and to evaluate their scientific rigor. We found relatively low, but stable prevalence with only 28 publications addressing all three factors of the social validity construct (i.e., goals, procedures, outcomes). We conducted an in-depth analysis of the scientific rigor of these 28 publications. Social validity remains an understudied construct in SCR, and the scientific rigor of social validity assessments is often lacking. Implications and future directions are discussed.

    This article reviews empirical support for treatments targeting women sexually assaulted during adolescence or adulthood. Thirty-two articles were located using data from 20 separate samples. Of the 20 samples, 12 targeted victims with chronic symptoms, three focused on the acute period post-assault, two included women with chronic and acute symptoms, and three were secondary prevention programs. The majority of studies focus on posttraumatic stress disorder (PTSD), depression, and/or anxiety as treatment targets. Cognitive Processing Therapy and Prolonged Exposure have garnered the most support with this population. Stress Inoculation Training and Eye Movement Desensitization and Reprocessing also show some efficacy. Of the four studies that compared active treatments, few differences were found. Overall, cognitive behavioral interventions lead to better PTSD outcomes than supportive counseling does. However, even in the strongest treatments more than one-third of women retain a PTSD diagnosis at post-treatment or drop out of treatment. Discussion highlights the paucity of research in this area, methodological limitations of examined studies, generalizability of findings, and important directions for future research at various stages of trauma recovery.

    Full Text Available Background Evidence-based policy is a term often applied in various field of public health including tobacco control policy. Strengthening evidence -based tobacco control policy development should also base on reliable evidence, in particular research approach. The coverage of tobacco control research under WHO FCTC guidelines is crucial issues. Methods A systematic literature review was conducted for identifying the gaps in tobacco control research. The search for relevant publications was done by the search engine. The key inclusion and exclusion criteria were defined, focusing on published original article conducting in Thai context, both English and Thai language in the past 5 years. The quality of articles was assessed. The text of articles was analyzed based on WHO FCTC articles, at totally 15 articles as well as the 2 nd National Strategic Plan for Tobacco Control 2015 - 2019. Results The initial search resulted in 1,048 abstracts. After applying the inclusion and exclusion criteria for two rounds, 176 original articles were selected for the review. In the article reviewed, the most of WHO FCTC articles applying into the research conceptual framework was article 20 (63.1% with the purpose of gain new knowledge on tobacco harms and effects on health and cross sectional survey design for surveillance tobacco use among various groups. The rest of articles were focused on research related WHO FCTC article 12 (31.0% and article 14 (19.3%. Three articles did not conducted as a research framework, articles 5.3, 9 - 10 and 19. However, those resulted were implemented in specific area, setting and target groups that's not applicable for scaling up. Conclusions The successful transformation of research results to effective tobacco control policy under WHO FCTC depends on various issuers, especially time-based for conducting the research that sufficient to prove the project outcome and appropriate budget for comprehensive research design, coverage

    Aims and scope This article reviews the available quantitative research on psychosocial adjustment and mental health among children (age reintegration in CAAFAG. Abduction, age of conscription, exposure to violence, gender, and community stigma were associated with increased internalizing and externalizing mental health problems. Family acceptance, social support, and educational/economic opportunities were associated with improved psychosocial adjustment. Conclusions Research on the social reintegration and psychosocial adjustment of former child soldiers is nascent. A number of gaps in the available literature warrant future study. Recommendations to bolster the evidence base on psychosocial adjustment in former child soldiers and other war-affected youth include more studies comprising longitudinal study designs, and validated cross-cultural instruments for assessing mental health, as well as more integrated community-based approaches to study design and research monitoring.

    Full Text Available Abstract Background Community capability is the combined influence of a community’s social systems and collective resources that can address community problems and broaden community opportunities. We frame it as consisting of three domains that together support community empowerment: what communities have; how communities act; and for whom communities act. We sought to further understand these domains through a secondary analysis of a previous systematic review on community participation in health systems interventions in low and middle income countries (LMICs. Methods We searched for journal articles published between 2000 and 2012 related to the concepts of “community”, “capability/participation”, “health systems research” and “LMIC.” We identified 64 with rich accounts of community participation involving service delivery and governance in health systems research for thematic analysis following the three domains framing community capability. Results When considering what communities have, articles reported external linkages as the most frequently gained resource, especially when partnerships resulted in more community power over the intervention. In contrast, financial assets were the least mentioned, despite their importance for sustainability. With how communities act, articles discussed challenges of ensuring inclusive participation and detailed strategies to improve inclusiveness. Very little was reported about strengthening community cohesiveness and collective efficacy despite their importance in community initiatives. When reviewing for whom communities act, the importance of strong local leadership was mentioned frequently, while conflict resolution strategies and skills were rarely discussed. Synergies were found across these elements of community capability, with tangible success in one area leading to positive changes in another. Access to information and opportunities to develop skills were crucial to community

    School climate has received increased attention in education policy and, in response, educators are seeking strategies to improve the climates of their middle and high schools. However, there has been no comprehensive synthesis of the empirical evidence for what works in school climate improvement. This article constitutes a systematic review of programs and practices with empirical support for improving school climate. It defines school climate and provides a methodology for identifying and evaluating relevant studies. The review identified 66 studies with varying strength of evidence and nine common elements that cut across reviewed programs and practices. The review concludes with a critical appraisal of what we know about school climate improvement and what we still need to know. © Society for Community Research and Action 2016.

    In Korea, there has been a concern on tsumami risks for the Nuclear Power Plants since the 1983 Nihonkai-Chubu earthquake tsunami. The maximum run-up height reached 4 m to north of the Ulchin nuclear power plant site. The east coast of Korea was also attacked by a few meters high tsunami generated by the 1993 Hokkaido Nansei-Oki earthquake. Both source areas of them were in the areas western off Hokkaido to the eastern margin of the Japan Sea, which remains another tsunami potential. Therefore it is necessary to study tsunami risks for coast of Korea by means of geological investigation and numerical simulation. Historical records of earthquake and tsunami in the Japan Sea were re-compiled to evaluate tsunami potential. A database of marine active faults in the Japan Sea was compiled to decide a regional potential of tsunami. Many developed reverse faults are found in the areas western off Hokkaido to the eastern margin of the Japan Sea. The authors have found no historical earthquake in the East China Sea which caused tunami observed at coast of Korea. Therefore five fault models were determined on the basis of the analysis results of historical records and recent research results of fault parameter and tunami. Tsunami heights were estimated by numerical simulation of nonlinear dispersion wave theory. The results of the simulations indicate that the tsunami heights in these cases are less than 0.25 m along the coast of Korea, and the tsunami risk by these assumed faults does not lead to severe impact. It is concluded that tsunami occurred in the areas western off Hokkaido to the eastern margin of the Japan Sea leads the most significant impact to Korea consequently. (author)

    The importance of psychosocial factors in the management of bronchial asthma has long been recognized. This paper offers a review of research published in the English language related to psychosocial aspects of bronchial asthma in Arab countries. Several databases (PubMed, Science Direct, Springer Link, ERIC, and PsychInfo) were searched using the following keywords: bronchial asthma, Arab countries, Algiers, Bahrain, Comoros, Djibouti, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Mauritania, Morocco, Oman, Palestine (West Bank, Gaza), Qatar, Saudi Arabia, Syria, Tunisia, Sudan, Somalia; United Arab Emirates, and Yemen. Thirty-two studies were conducted in 9 Arab countries. Almost all studies found were published in the last fourteen years with an apparent increasing rate in the last five years. In descending order, these studies addressed: knowledge of and attitudes toward asthma, quality of life, behavioral and emotional problems and factors related to academic achievement. The main results of the studies reviewed were: (a) physicians', school staff's, and parents' knowledge of and attitudes toward asthma were generally unsatisfactory, (b) in-service asthma education programs significantly impacted parent and staff knowledge and attitudes, and asthma management practices, (c) quality of life in children and adolescents was significantly adversely affected by asthma, (d) asthma was a common cause of school absenteeism, and had a significant negative impact on academic achievement of students, and (e) students with asthma had significantly higher rates of behavioral and emotional difficulties compared to students without asthma. The paper concludes with a discussion about the implications of these results and a call for further research in this area.

    Big data technologies are increasingly used for biomedical and health-care informatics research. Large amounts of biological and clinical data have been generated and collected at an unprecedented speed and scale. For example, the new generation of sequencing technologies enables the processing of billions of DNA sequence data per day, and the application of electronic health records (EHRs) is documenting large amounts of patient data. The cost of acquiring and analyzing biomedical data is expected to decrease dramatically with the help of technology upgrades, such as the emergence of new sequencing machines, the development of novel hardware and software for parallel computing, and the extensive expansion of EHRs. Big data applications present new opportunities to discover new knowledge and create novel methods to improve the quality of health care. The application of big data in health care is a fast-growing field, with many new discoveries and methodologies published in the last five years. In this paper, we review and discuss big data application in four major biomedical subdisciplines: (1) bioinformatics, (2) clinical informatics, (3) imaging informatics, and (4) public health informatics. Specifically, in bioinformatics, high-throughput experiments facilitate the research of new genome-wide association studies of diseases, and with clinical informatics, the clinical field benefits from the vast amount of collected patient data for making intelligent decisions. Imaging informatics is now more rapidly integrated with cloud platforms to share medical image data and workflows, and public health informatics leverages big data techniques for predicting and monitoring infectious disease outbreaks, such as Ebola. In this paper, we review the recent progress and breakthroughs of big data applications in these health-care domains and summarize the challenges, gaps, and opportunities to improve and advance big data applications in health care.

    The association between workplace bullying and sickness absence remains unclear. This paper presents a systematic review and meta-analysis of research on the association. We conducted a systematic review and meta-analysis of published primary studies on workplace bullying and sickness absence. Studies based on prospective design or registry data on sickness absence were included. Cross-sectional studies with self-reported sickness absence were excluded. Seventeen primary studies were included in the review, sixteen originated from the Nordic countries and fifteen included registry data on sickness absence. All but one study found that exposure to workplace bullying was associated with increased risk of sickness absence. A meta-analysis of ten independent studies showed that exposure to bullying increased the risk of sickness absence (odds ratio 1.58, 95% CI 1.39-1.79). Five studies included variables that moderated the association between bullying and absenteeism. None of the studies included mediating variables. No studies examined sickness absence as a risk factor for later exposure to bullying. Following the GRADE guidelines, the evidence for an association between bullying and sickness absence is moderate. Workplace bullying is a risk factor for sickness absence, but the mechanisms to explain this relationship are not sufficiently described. It is unclear whether sickness absence predicts later exposure to bullying. While, the methodological quality of the reviewed studies was high, the knowledge base is small. There is a need for more research on how and when bullying is related to sickness absence and the possible bidirectional relationships involved.

    Full Text Available This systematic review analyzed articles focused on the relationship between environment (physical, built, perceived, and social and smoking, alcohol drinking, physical activity, diet, and obesity in Brazil. Studies published between 19952011 were retrieved from seven databases and hand searches. Based on the 42 articles reviewed, gaps were identified and recommendations were made for future research. Despite a growing number of studies, the Brazilian literature is still limited. The increase of articles in 2010-2011 coincided with the diversification of lifestyles studied, although physical activity domain remains predominant. Most studies analyzed neighborhood settings and used subjective measures for lifestyle and for environment. The presence of recreational facilities was the main physical environment aspect studied, while safety from crime was the prominent social environment factor. More research is needed to yield a rich body of evidence that leads to theoretical and methodological advances, and that supports interventions aimed at creating healthy environments.

    2013-01-01

    The high incidence of fatal diseases, inequitable access to health care, and socioeconomic disparities in India generate plentiful clinical bad news including diagnosis of a life-limiting disease, poor prognosis, treatment failure, and impending death. These contexts compel health care professionals to become the messengers of bad news to patients and their families. In global literature on breaking bad news, there is very little about such complex clinical interactions occurring in India or guiding health care providers to do it well. The purpose of this article is to identify the issues for future research that would contribute to the volume, comprehensiveness, and quality of empirical literature on breaking bad news in clinical settings across India. Towards this end, we have synthesized the studies done across the globe on breaking bad news, under four themes: (a) deciding the amount of bad news to deliver; (b) attending to cultural and ethical issues; (c) managing psychological distress; and (d) producing competent messengers of bad news. We believe that robust research is inevitable to build an indigenous knowledge base, enhance communicative competence among health care professionals, and thereby to improve the quality of clinical interactions in India.

    Operator achievement and maintenance of situation awareness (SA) in nuclear power plant (NPP) process control has emerged as an important concept in defining effective relationships between humans and automation in this complex system. A literature review on factors influencing SA revealed several variables to be important to team SA, including the overall task and team goals, individual tasks, team member roles, and the team members themselves. Team SA can also be adversely affected by a range of factors, including stress, mental over- or under-loading, system design (including human-machine interface design), complexity, human error in perception, and automation. Our research focused on the analysis of 'shared' SA and team SA among an assumed three-person, main-control-room team. Shared SA requirements represent the knowledge that is held in common by NPP operators, and team SA represents the collective, unique knowledge of all operators. The paper describes an approach to goal-directed task analysis (GDTA) applied to NPP main control room operations. In general, the GDTA method reveals critical operator decision and information requirements. It identifies operator SA requirements relevant to performing complex systems control. The GDTA can reveal requirements at various levels of cognitive processing, including perception, comprehension and projection, in NPP process control. Based on the literature review and GDTA approach, a number of potential research issues are proposed with an aim toward understanding and facilitating team SA in NPP process control. (authors)

  20. Passive writers and understanding critics. Institution and interpretation in the research field of the anthropology of literature

    Directory of Open Access Journals (Sweden)

    Aldona Kopkiewicz

    2013-01-01

    Full Text Available This essay presents a polemic against the anthropology of literature. The author examines the relation between the ethics of interpretation and the discourse of the anthropology of literature as well as cultural studies. She also shows theoretical conditions under which a textual subject appears to be weak and passive and thus becomes just a field in which a researcher can inscribe various cultural identities. In this way a researcher tries to restitute the subject after its poststructural “death”, but he/she might do that only by mediation through social and cultural identities, which he/she actually examines. On the practical level this entanglement causes a situation in which writers and artists create works that fulfill institutional expectations. It would be therefore necessary to establish to what extent an anthropological approach towards a text enables us to invent new models of subjectivity. Without this it would be difficult to consider literary/cultural studies to be a truly critical discipline based on independent, yet collaborative reflection to be found in theoretical and artistic texts alike.

  1. Research of fluid-induced pressure fluctuation due to impeller-volute interaction in a centrifugal pump

    The fluid pressure fluctuation generated by unsteady flow is a very important factor to induce vibration of the centrifugal pump. The relative movement between impeller and volute generates an unsteady interaction which affects not only the overall pump performance, but is also responsible for pressure fluctuations. Pressure fluctuations interact with the volute casing or even with the circuit and give rise to dynamic effects over the mechanical parts, which are one of the most important sources of vibration and hydraulic noise. To investigate the flow characteristic in the centrifugal pump, the unsteady flow is simulated by CFD methods in this paper. Unsteady flow characteristic in the centrifugal pump is obtained considering the impeller-volute interaction in the whole flow field. Based on the unsteady flow simulation, amplitude-frequency characteristics of the pressure fluctuation in the centrifugal pump are obtained through setting up monitoring point at the impeller outlet. The research shows that the frequency component include the blade passing frequency as the main component, the multiplication of blade passing frequency, and the harmonic interference due to the unsteady flow

  2. Working with interpreters in cross-cultural qualitative research in the context of a developing country: systematic literature review.

    This article is a report of a systematic literature review describing how cross-cultural researchers conducted qualitative studies with interpreters in Tanzania. The purpose was to draw methodological implications for working with interpreters within the context of developing countries. In a growing number of cross-cultural nursing studies in developing countries, interpreters play a crucial role for imparting verbal and cultural understanding. In many studies, however, the interpreters' role and their influences on the findings are not adequately described, and therefore the study credibility is weakened. Cross-cultural qualitative studies conducted with interpreters in Tanzania were searched in four databases. Meeting our inclusion criteria were 20 studies published from 1994-2009. We used Garrard's Matrix Method following Wallin and Ahlström's framework to analyse how cross-cultural researchers described the role of interpreters. We identified three major patterns of how researchers worked with interpreters: (i) invisible assistance, (ii) independent fieldwork and (iii) integrated collaboration. In many studies, interpreters' information was limited. They were often asked to collect data in the field without the presence of the researcher. They were integrated into the research process beyond data collection, such as subject recruitment, review of interviews, transcription and translation and analysis. From planning of research to dissemination of the findings, nurse researchers should carefully consider interpreters' influences on the findings. They may use a set of questions we developed for working with interpreters in developing countries to systematically describe the interpreter's role and maximize their research credibility. © 2012 Blackwell Publishing Ltd.

    Though cupping therapy has been used in China for thousands of years, there has been no systematic summary of clinical research on it.This review is to evaluate the therapeutic effect of cupping therapy using evidence-based approach based on all available clinical studies. We included all clinical studies on cupping therapy for all kinds of diseases. We searched six electronic databases, all searches ended in December 2008. We extracted data on the type of cupping and type of diseases treated. 550 clinical studies were identified published between 1959 and 2008, including 73 randomized controlled trials (RCTs), 22 clinical controlled trials, 373 case series, and 82 case reports. Number of RCTs obviously increased during past decades, but the quality of the RCTs was generally poor according to the risk of bias of the Cochrane standard for important outcome within each trials. The diseases in which cupping was commonly employed included pain conditions, herpes zoster, cough or asthma, etc. Wet cupping was used in majority studies, followed by retained cupping, moving cupping, medicinal cupping, etc. 38 studies used combination of two types of cupping therapies. No serious adverse effects were reported in the studies. According to the above results, quality and quantity of RCTs on cupping therapy appears to be improved during the past 50 years in China, and majority of studies show potential benefit on pain conditions, herpes zoster and other diseases. However, further rigorous designed trials in relevant conditions are warranted to support their use in practice.

    This study aims to examine trends in studies of teens' health information behaviour. Eighty-two articles published between 2000 and 2012 were selected and analysed in various aspects: health topics by year, information sources, data collection methods, use of theories and models, collaborative and interdisciplinary efforts and published journals. Fifty-seven per cent of the studies focused on specific health topics, such as sexual health, while the rest covered general health topics. Almost half of the studies examined how teens search for and use health information on the Internet. Surveys were the most popular data collection technique. Only 12.2% were based on a theory or model. About 42% were conducted collaboratively by authors from multiple disciplines. With the increasing attention to specific health topics and online resources, the health information behaviour of teens has been examined more frequently since the mid-2000s. Its interdisciplinary nature was evidently shown from various disciplines that the authors were affiliated with and the journals of the published studies represented. This study suggests that there should be efforts to reflect new technology tools, apply mixed methods and increase the engagement level of collaboration to evolve this research domain. © 2014 The authors.

    This study reviewed research conducted on the psychological aspects of epilepsy in Arab countries. Several databases (Medline, PubMed, Science Direct, Springer Link, and PsycInfo) were searched using the following two sets of search words: (1) Arab, Jordan, Lebanon, United Arab Emirates (UAE), Bahrain, Qatar, Kuwait, Oman, Saudi Arabia, Syria, Iraq, Egypt, Yemen, Tunisia, Libya, Morocco, Algiers, Palestine, Mauritania, Djibouti, Sudan, Comoros, and Somalia; and (2) epilepsy, seizure disorders, and convulsive disorders. Fifty-one studies were conducted in 12 Arab states. Social/emotional, employment, and other problems; knowledge and attitudes; and quality of life (QOL) were the most commonly measured parameters of psychosocial aspects of epilepsy in Arab countries. Results revealed elevated levels of depression and anxiety, a decline in cognitive function, various behavioral problems, sexual dysfunction, and underemployment among persons with epilepsy (PWE). Misconceptions about epilepsy were found to be prevalent. While many studies reported limited knowledge of epilepsy, some studies found an average knowledge. Negative attitudes toward epilepsy were reported in most studies, and moderately positive attitudes were reported in some studies. Finally, PWE showed low overall QOL scores in the majority of studies. © 2013.

    Anesthesiology has advanced in China over the past decade. We compared the trends in publication of anesthesiology articles from China between 2005 and 2014 with the trends in 5 developed countries. We included all journals listed in the ''Anesthesiology'' category of Journal Citation Reports. Anesthesiology-related publications from 2005 to 2014 were retrieved from the PubMed and Web of Knowledge online databases. The total number of articles, publication type categories, number of citations, and citation rate (number of citations/years since publication) were analyzed. The sample size was the n = 10 years for all confidence intervals and P values. We additionally evaluated the total number of articles published in the 10 top-ranking journals. From 2005 to 2014, 41,344 articles were published in anesthesiology journals. Of these, 3.07% were contributed by authors from Chinese institutions. Although this contribution was less than the Unites States, Great Britain, Germany, France, or Japan, publications from Chinese institutions grew at an annual rate of 13% (95% confidence interval: 3.08%-23.38%, P United States (2.71, P = 0.545), Great Britain (2.57, P = 0.999), Germany (2.35, P = 0.999), France (1.50, P = 0.520), and Japan (1.24, P = 0.065). In the 10 highest impact anesthesiology journals, China published 780 articles during the decade. The 3 journals with the most publications from Chinese institutions were Anesthesia & Analgesia, Anesthesiology, and Acta Anaesthesiologica Scandinavica. In the studied decade, anesthesiology research published by Chinese institutions lagged behind publications from developed countries. There was a steady increase in the number of articles every year, resulting in recent rates of publication similar to several developed countries. The citation rate of articles from Chinese institutions was similar to the citation rate of articles from developed countries, indicating that the quality of articles from China in these journals is

    Over the past decade, chronic kidney disease (CKD) has become an area of intensive clinical and epidemiological research. Despite the clarity provided by the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, there appears to be within the CKD research literature significant disagreement on how to define CKD and measure kidney function. The objectives of this study were to investigate the variety of methods used to define CKD and to measure kidney function in original research papers as well as to investigate whether the quality of the journal had any effect on the quality of the methodology used. This was a descriptive review and not a meta-analysis. Information was extracted from each article including publication details (including the journal's impact factor), definition of CKD, method used to estimate kidney function and quantity of serum creatinine readings used to define CKD. An electronic search of MEDLINE through OVID was completed using the search term CKD. The search was limited to articles in English published in 2009. Studies were included in the review only if they were original research articles including patients with CKD. Articles were excluded if they reported data from a paediatric population, a population solely on dialysis or if there was no full-text access through OVID. Each article was assessed for quality with respect to using KDOQI CKD definition criteria. A description of the pooled data was completed and chi-square tests were used to investigate the relation between article quality and journal quality. Analysis was carried out using SPSS (15.0) and a P-value of definitions are being used in original research articles to define CKD and measure kidney function which calls into question the validity and reliability of such research findings and associated clinical guidelines. International consensus is urgently required to improve validity and generalizability of CKD research findings.

    Little has been published about the historical development of scientific evidence in the physical activity (PA) and public health research field. The study aimed to examine the evolution of knowledge in this field. A structured literature review using formal citation network analysis methods was conducted in June-2016. Using a list of influential PA publications identified by domain experts, a snowball sampling technique was used to build a compact citation network of 141 publications that represents the backbone of the field. Articles were coded by study type and research team characteristics, then analyzed by visualizing the citation network and identifying research clusters to trace the evolution of the field. The field started in the 1950s, with a health sciences focus and strong North American and European leadership. Health outcome studies appeared most frequently in the network and policy and interventions least. Critical articles on objective measurement and public policy have influenced the progress from an emphasis on health outcomes research at early stages in the field to the more recent emerging built environment and global monitoring foci. There is only modest cross-citation across types of study. To our knowledge, this paper is the first to systematically describe the development of research on PA and public health. The key publications include fundamental ideas that remain citable over time, but notable research and dissemination gaps exist and should be addressed. Increasing collaboration and communication between study areas, encouraging female researchers, and increasing studies on interventions, evaluation of interventions and policy are recommended.

    OBJECTIVE Markov modeling is a clinical research technique that allows competing medical strategies to be mathematically assessed in order to identify the optimal allocation of health care resources. The authors present a review of the recently published neurosurgical literature that employs Markov modeling and provide a conceptual framework with which to evaluate, critique, and apply the findings generated from health economics research. METHODS The PubMed online database was searched to identify neurosurgical literature published from January 2010 to December 2017 that had utilized Markov modeling for neurosurgical cost-effectiveness studies. Included articles were then assessed with regard to year of publication, subspecialty of neurosurgery, decision analytical techniques utilized, and source information for model inputs. RESULTS A total of 55 articles utilizing Markov models were identified across a broad range of neurosurgical subspecialties. Sixty-five percent of the papers were published within the past 3 years alone. The majority of models derived health transition probabilities, health utilities, and cost information from previously published studies or publicly available information. Only 62% of the studies incorporated indirect costs. Ninety-three percent of the studies performed a 1-way or 2-way sensitivity analysis, and 67% performed a probabilistic sensitivity analysis. A review of the conceptual framework of Markov modeling and an explanation of the different terminology and methodology are provided. CONCLUSIONS As neurosurgeons continue to innovate and identify novel treatment strategies for patients, Markov modeling will allow for better characterization of the impact of these interventions on a patient and societal level. The aim of this work is to equip the neurosurgical readership with the tools to better understand, critique, and apply findings produced from cost-effectiveness research.

    Universities, public institutions, and the transfer of knowledge to the private sector play a major role in the development of medical technologies. The decisions of universities and public institutions regarding the transfer of knowledge impact the accessibility of the final product, making it easier or more difficult for consumers to access these products. In the case of medical research, these products are pharmaceuticals, diagnostics, or medical procedures. The ethical dimension of access to these potentially lifesaving products is apparent and distinguishes the transfer of medical knowledge from the transfer of knowledge in other areas. While the general field of technology transfer from academic and public to private actors is attracting an increasing amount of scholarly attention, the specifications of knowledge transfer in the medical field are not as well explored. This review seeks to provide a systematic overview and analysis of the qualitative literature on the characteristics and determinants of knowledge transfer in medical research and development. The review systematically searches the literature for qualitative studies that focus on knowledge transfer characteristics and determinants at medical academic and public research institutions. It aims at identifying and analyzing the literature on the content and context of knowledge transfer policies, decision-making processes, and actors at academic and public institutions. The search strategy includes the databases PubMed, Web of Science, ProQuest, and DiVa. These databases will be searched based on pre-specified search terms. The studies selected for inclusion in the review will be critically assessed for their quality utilizing the Qualitative Research Checklist developed by the Clinical Appraisal Skills Programme. Data extraction and synthesis will be based on the meta-ethnographic approach. This review seeks to further the understanding of the kinds of transfer pathways that exist in medical

    The idea that human well-being (WB) can be supported and even enhanced by using, producing, buying, selling and consuming less `stuff' is anathema to many living under consumer capitalism. Yet a growing research literature actually finds that frequent engagement in pro-ecological behaviours (PEBs) is positively correlated with personal WB. This paper reviews data relevant to three possible explanations for the apparent compatibility of PEBs and WB: (i) engaging in PEBs leads to psychological need satisfaction, which in turn causes WB; (ii) being in a good mood causes people to engage in more prosocial behaviours, including PEBs; and (iii) personal characteristics and lifestyles such as intrinsic values, mindfulness and voluntary simplicity cause both PEBs and WB. Because each explanation has some empirical support, I close by reflecting on some relevant interventions and policies that could strengthen each of these three pathways and thereby promote living both well and sustainably. This article is part of the themed issue 'Material demand reduction'.

    relationships, and governance and facilitation arrangements, especially the style of leadership and how conflict is managed). In both the literature review and the case study, co-creation "failures" could often be tracked back to abandoning (or never adopting) these principles. All co-creation models made strong claims for significant and sustainable societal impacts as a result of the adaptive and developmental research process; these were illustrated in the case study. Co-creation models have high potential for societal impact but depend critically on key success principles. To capture the nonlinear chains of causation in the co-creation pathway, impact metrics must reflect the dynamic nature and complex interdependencies of health research systems and address processes as well as outcomes. © 2016 Milbank Memorial Fund.

    Conway, Mike

    2014-12-22

    The rise of social media and microblogging platforms in recent years, in conjunction with the development of techniques for the processing and analysis of "big data", has provided significant opportunities for public health surveillance using user-generated content. However, relatively little attention has been focused on developing ethically appropriate approaches to working with these new data sources. Based on a review of the literature, this study seeks to develop a taxonomy of public health surveillance-related ethical concepts that emerge when using Twitter data, with a view to: (1) explicitly identifying a set of potential ethical issues and concerns that may arise when researchers work with Twitter data, and (2) providing a starting point for the formation of a set of best practices for public health surveillance through the development of an empirically derived taxonomy of ethical concepts. We searched Medline, Compendex, PsycINFO, and the Philosopher's Index using a set of keywords selected to identify Twitter-related research papers that reference ethical concepts. Our initial set of queries identified 342 references across the four bibliographic databases. We screened titles and abstracts of these references using our inclusion/exclusion criteria, eliminating duplicates and unavailable papers, until 49 references remained. We then read the full text of these 49 articles and discarded 36, resulting in a final inclusion set of 13 articles. Ethical concepts were then identified in each of these 13 articles. Finally, based on a close reading of the text, a taxonomy of ethical concepts was constructed based on ethical concepts discovered in the papers. From these 13 articles, we iteratively generated a taxonomy of ethical concepts consisting of 10 top level categories: privacy, informed consent, ethical theory, institutional review board (IRB)/regulation, traditional research vs Twitter research, geographical information, researcher lurking, economic value

    To conduct a systematic review of the literature examining risk and protective factors of alcohol related negative consequences (ARNCs) among adolescents. We conducted a systematic search of original empirical articles published between January 1, 1990 and June 1, 2015. The qualitative synthesis was performed using the Theory of Triadic Influence as a framework. Fifty-two studies were reviewed. Intrapersonal (e.g., personality traits, drinking motives and expectancies, depression), interpersonal (e.g., parental and peer alcohol use, violence exposure) and attitudinal factors (e.g., media exposure to alcohol, religiosity) influence ARNCs. Emerging evidence of new trends contributing to ARNCs include ready mixed alcohol drinks and childhood trauma and abuse. Risk factors from all domains of influence were observed. More research is needed on protective factors and how alcohol use interacts with preventive factors in predicting ARNCs. The conceptualization of negative consequences varies significantly between studies and may impact the external validity of previous research.

    Remy-Largeau, Isabelle

    2011-12-01

    Very recently the concept of care has burst on the French philosophical scene. What are the contours of this developing "philosophy of care"? How does it place itself in relation to what are today called the ethics of care? And how does it take account of nursing care, as a discipline understood in its triple dimension: social, pedagogical and epistemological? The research presented in this paper examines some of the founding texts of this philosophy of care through the prism of these questions. It is the partial presentation of a reflection developed from a literature review that will include two other sections. The second section will focus on studying the way in which the ethics of care allow for nursing care and enter into dialogue with the nascent philosophy of care. The third will focus, conversely, on the way nurses integrate reflections derived from ethics of care and the philosophy of care into the evolution of their own discipline and contribute back to the development of a philosophy of care. These three questions are in turn part of more extensive research carried out in preparation for a philosophy thesis. They are meant as an invitation and a contribution towards what we hope will be a successful encounter between philosophy and nursing care.

    This report presents recently published information and on-going research on the various areas of gas supersaturation. Growing interest in the effects of chronic gas supersaturation on aquatic animals has been due primarily to heavy mortality of salmonid species under hatchery conditions. Extensive examination of affected animals has failed to consistently identify pathogenic organisms. Water quality sampling has shown that chronic levels of gas supersaturation are commonly present during a significant period of the year. Small marine fish larvae are significantly more sensitive to gas supersaturation than salmonids. Present water quality criteria for gas supersaturation are not adequate for the protection of either salmonids under chronic exposure or marine fish larvae, especially in aquaria or hatcheries. To increase communication between interested parties in the field of gas supersaturation research and control, addresses and telephone numbers of all people responding to the questionnaire are included. 102 refs.

    Research on health inequalities can be instrumental in drawing attention to the health of socioeconomically vulnerable groups in India in the context of rapid economic growth. It can shape the dialogue for public health action, emphasizing the need for greater investments in health, and monitor effectiveness of health programs. Our objective was to examine trends in studies on health inequalities in the last 25 years. We conducted a systematic literature review of studies on health inequalities published from 1990. The year, 1990, marked the beginning of economic reforms and liberalization in India. We searched PubMED using key terms to identify 8800 articles between 1990 and 2016; we identified 1,312 final studies for review. Key domains of analysis included measures of equity, health outcomes, populations studied, year of publication, study methodology, study focus (descriptive versus analytical), and location of main author. We found an increase in studies on health inequalities after 2005. About 88 % of the studies utilized quantitative methods for analysis. About 8 % of the studies related to health interventions or programs; the number of intervention studies have been increasing since 2010. A majority of studies were led by authors based in India. Early studies focused on mortality, communicable and non-communicable diseases, and nutrition, while later studies have focused on non-communicable diseases, mental health, risk factors, and injuries. Studies on women and children comprised nearly half of the literature; studies on the youth (15-24 years or as defined by the study) and elderly have been rising. Wealth and income were the most common measures of equity, followed by education and gender. The proportion of studies on wealth, education, region and caste have stayed consistent over time, while studies on gender disparities have been rising. In a country as diverse as India with large social inequalities combined with rapid economic growth, research

    The United Kingdom (UK), alongside other industrialised countries, is experiencing a shortage of nurses partly due to low retention rates. Job satisfaction has been highlighted as a contributing factor to intent to leave and turnover, yet this is a complex area with many elements affecting its measurement. The aim of this paper is to explore the impact of job satisfaction components on intent to leave and turnover for hospital-based nurses in order to identify the most influential factors. To achieve this, a systematic search of the literature was undertaken to identify relevant international research. Three databases (i.e. BNI, CINAHL and PsychInfo) were utilised, resulting in nine articles that met the inclusion criteria. Four recurrent themes were identified in the literature: leadership, educational attainment, pay and stress. The key findings suggest that stress and leadership issues continue to exert influence on dissatisfaction and turnover for nurses. Level of education achieved and pay were found to be associated with job satisfaction, although the results for these factors were not consistent. Investigating possible changes over time in sources of dissatisfaction revealed that factors related to the work environment rather than individual or demographic factors were still of most importance to nurses' turnover intentions. The differences found to occur across work settings necessitates analysis of job satisfaction at ward level, and the contribution of qualitative methods to develop more detailed insight is emphasised. The inconsistent findings over time associated with the effects of educational attainment and pay on intent to leave suggest that it is imperative that sources of job satisfaction are reassessed in the light of ongoing changes.

    This is a rapid evidence review. The objective of this study was to gain an overview of the volume, nature and findings of studies regarding priorities for spinal cord injury (SCI) research. A worldwide literature search was conducted. Six medical literature databases and Google Scholar were searched for reviews in which the primary aim was to identify SCI research priorities. Two systematic reviews were identified-one of quantitative and one of qualitative studies. The quality of the reviews was variable. Collectively, the reviews identified 31 primary studies; 24 quantitative studies totalling 5262 participants and 7 qualitative studies totalling 120 participants. Despite the difference in research paradigms, there was convergence in review findings in the areas of body impairments and relationships. The vast majority of literature within the reviews focused on the SCI patient perspective. The reviews inform specific research topics and highlight other important research considerations, most notably those pertaining to SCI patients' perspectives on quality of life, which may be of use in determining meaningful research outcome measures. The views of other SCI research stakeholders such as researchers, clinicians, policymakers, funders and carers would help shape a bigger picture of SCI research priorities, ultimately optimising research outputs and translation into clinical practice and health policy change. Review findings informed subsequent activities in developing a regional SCI research strategy, as described in two companion papers. This project was funded by the Victorian Transport Accident Commission and the Australian and New Zealand SCI Network.

    Approximately 75% of suicides occur in low- and middle-income countries (LMICs) where rates of poverty are high. Evidence suggests a relationship between economic variables and suicidal behaviour. To plan effective suicide prevention interventions in LMICs we need to understand the relationship between poverty and suicidal behaviour and how contextual factors may mediate this relationship. We conducted a systematic mapping of the English literature on poverty and suicidal behaviour in LMICs, to provide an overview of what is known about this topic, highlight gaps in literature, and consider the implications of current knowledge for research and policy. Eleven databases were searched using a combination of key words for suicidal ideation and behaviours, poverty and LMICs to identify articles published in English between January 2004 and April 2014. Narrative analysis was performed for the 84 studies meeting inclusion criteria. Most English studies in this area come from South Asia and Middle, East and North Africa, with a relative dearth of studies from countries in Sub-Saharan Africa. Most of the available evidence comes from upper middle-income countries; only 6% of studies come from low-income countries. Most studies focused on poverty measures such as unemployment and economic status, while neglecting dimensions such as debt, relative and absolute poverty, and support from welfare systems. Most studies are conducted within a risk-factor paradigm and employ descriptive statistics thus providing little insight into the nature of the relationship. More robust evidence is needed in this area, with theory-driven studies focussing on a wider range of poverty dimensions, and employing more sophisticated statistical methods.

    To examine and map research on minimum data sets linked to nursing practice and the fundamentals of care. Another aim was to identify gaps in the evidence to suggest future research questions to highlight the need for standardisation of terminology around nursing practice and fundamental care. Addressing fundamental care has been highlighted internationally as a response to missed nursing care. Systematic performance measurements are needed to capture nursing practice outcomes. Overview of the literature framed by the scoping study methodology. PubMed and CINAHL were searched using the following inclusion criteria: peer-reviewed empirical quantitative and qualitative studies related to minimum data sets and nursing practice published in English. No time restrictions were set. Exclusion criteria were as follows: no available full text, reviews and methodological and discursive studies. Data were categorised into one of the fundamentals of care elements. The review included 20 studies published in 1999-2016. Settings were mainly nursing homes or hospitals. Of 14 elements of the fundamentals of care, 11 were identified as measures in the included studies, but their frequency varied. The most commonly identified elements concerned safety, prevention and medication (n = 11), comfort (n = 6) and eating and drinking (n = 5). Studies have used minimum data sets and included variables linked to nursing practices and fundamentals of care. However, the relations of these variables to nursing practice were not always clearly described and the main purpose of the studies was seldom to measure the outcomes of nursing interventions. More robust studies focusing on nursing practice and patient outcomes are warranted. Using minimum data sets can highlight the nurses' work and what impact it has on direct patient care. Appropriate models, systems and standardised terminology are needed to facilitate the documentation of nursing activities. © 2017 John Wiley & Sons Ltd.

    An increasing number of behavioral and psychosocial cancer interventions incorporate new media elements that are digital, networked, and interactive. However, it is unclear to what extent new media is being leveraged to benefit underserved racial and ethnic groups who disproportionately bear the burden of cancer. This inquiry is timely in light of growing evidence that these groups are receptive to new media. A systematic literature review was conducted to assess the inclusion of these groups in research on cancer-related new media interventions and use of new media to reduce racial and ethnic cancer disparities. A systematic search of three databases was conducted for articles published between January 2000 and March 2012 that presented studies of user experience with a behavioral or psychosocial cancer-related intervention with at least one new media component. Thirty-six articles were included in the final review. In about one-quarter of the studies, less than 20% of participants were African American, Latino, Asian American, or American Indian. In less than 10% of the studies, 80% or more of the samples were members of the aforementioned groups. Almost one-third of the studies reviewed were categorized as disparity focused but limited data were available on racial and ethnic differences in responses to new media interventions. Findings suggest that the promise and potential of new media cancer interventions are largely unrealized among the underserved. Additional research is needed to investigate a wide range of issues related to the development and delivery of such interventions in diverse racial and ethnic groups.

    Mother-infant bed-sharing has been a common practice for centuries. Understanding the reasons parents choose to bed-share can help tailor safe sleep education. The purpose of this article was to systematically review the international literature on: (1) reasons parents bed-share, (2) the cultural context of bed-sharing, and (3) implications for interventions and future research. The search occurred August-September 2013 via PubMed, CINAHL, and Psyc INFO using the terms: "infant," "sleep," "bed shar*," "co sleep*," "sleep location," "sleep practices," and "sleep arrangements," alone or in combination. Google Scholar was searched using: "bed share," "bed sharing," "co sleep," and "co sleeping." Inclusion criteria were: (1) referenced bed-sharing with infants 12 months or younger; (2) provided reasons for bed-sharing; and (3) published between 1990 and 2013. Studies were excluded if they focused on disorders such as epilepsy, breathing disorders, or among multi-gestational infants. Narrative synthesis was used to summarize findings. Thirty-four studies met inclusion criteria. The main themes around bed-sharing based on this synthesis included: (1) breastfeeding, (2) comforting, (3) better/more sleep, (4) monitoring, (5) bonding/attachment, (6) environmental, (7) crying, (8) tradition, (9) disagree with danger, and (10) maternal instinct. Findings suggest that future research should examine parents' decision-making process on infant sleep location, including how they weigh personal reasons and sources of advice. Public health interventions should incorporate the particular reasons of the population they are targeting. Clinicians should discuss infant sleep environment with each family, along with their motivations for choosing this environment, and work within that framework to address the safety of the sleep environment.

    Many individuals with traumatic brain injury (TBI) are young and could have many years of productivity ahead of them. However, cognitive impairments may hinder individuals' ability to perform daily tasks. Assistive technology for cognition (ATC) can be effective in helping compensate for cognitive impairments. This study examined the current state of the research on using ATCs to support daily activities for individuals with cognitive disabilities that are due to TBI. A comprehensive systematic literature search was performed to identify peer-reviewed articles published between 2000 and 2015. To evaluate the nature of the research, qualitative data were extracted pertaining to recruitment, participant characteristics, intervention design, type of ATCs and their functions, matching individuals with ATCs, training for using the ATC, and outcomes. Research examining the effectiveness of ATCs as everyday compensatory tools for cognitive impairments that are due to TBI is limited. The majority of studies were case studies or quasi-experimental studies with small sample sizes. Studies showed positive associations between use of ATCs and individuals' abilities to perform tasks regardless of age, TBI severity, and time since injury. Future research should assess the match between the individual and the technology, study the impact of training on using ATCs, and analyze the usability of ATCs.

    Antidepressant (AD) use has been purported to increase the risk of breast and ovarian cancer, although both epidemiological and pre-clinical studies have reported mixed results. Previous studies in a variety of biomedical fields have found that financial ties to drug companies are associated with favorable study conclusions. We searched English-language articles in MEDLINE, PsychINFO, the Science Citations Index and the Cochrane Central Register of Controlled Clinical Trials (through November 2010). A total of 61 articles that assessed the relationship between breast and ovarian cancer and AD use and articles that examined the effect of ADs on cell growth were included. Multi-modal screening techniques were used to investigate researchers' financial ties with industry. A random effects meta-analysis was used to pool the findings from the epidemiological literature. Thirty-three percent (20/61) of the studies reported a positive association between ADs and cancer. Sixty-seven percent (41/61) of the studies reported no association or antiproliferative effect. The pooled odds ratio for the association between AD use and breast/ovarian cancer in the epidemiologic studies was 1.11 (95% CI, 1.03-1.20). Researchers with industry affiliations were significantly less likely than researchers without those ties to conclude that ADs increase the risk of breast or ovarian cancer. (0/15 [0%] vs 20/46 [43.5%] (Fisher's Exact test P = 0.0012). Both the pre-clinical and clinical data are mixed in terms of showing an association between AD use and breast and ovarian cancer. The possibility that ADs may exhibit a bi-phasic effect, whereby short-term use and/or low dose antidepressants may increase the risk of breast and ovarian cancer, warrants further investigation. Industry affiliations were significantly associated with negative conclusions regarding cancer risk. The findings have implications in light of the 2009 USPSTF guidelines for breast cancer screening and for the

    Multimorbidity, the co-occurrence of two or more chronic medical conditions within a single individual, is increasingly becoming part of daily care of general medical practice. Literature-based discovery may help to investigate the patterns of multimorbidity and to integrate medical knowledge for improving healthcare delivery for individuals with co-occurring chronic conditions. To explore the usefulness of literature-based discovery in primary care research through the key-case of finding associations between psychiatric and somatic diseases relevant to general practice in a large biomedical literature database (Medline). By using literature based discovery for matching disease profiles as vectors in a high-dimensional associative concept space, co-occurrences of a broad spectrum of chronic medical conditions were matched for their potential in biomedicine. An experimental setting was chosen in parallel with expert evaluations and expert meetings to assess performance and to generate targets for integrating literature-based discovery in multidisciplinary medical research of psychiatric and somatic disease associations. Through stepwise reductions a reference set of 21,945 disease combinations was generated, from which a set of 166 combinations between psychiatric and somatic diseases was selected and assessed by text mining and expert evaluation. Literature-based discovery tools generate specific patterns of associations between psychiatric and somatic diseases: one subset was appraised as promising for further research; the other subset surprised the experts, leading to intricate discussions and further eliciting of frameworks of biomedical knowledge. These frameworks enable us to specify targets for further developing and integrating literature-based discovery in multidisciplinary research of general practice, psychology and psychiatry, and epidemiology.

  18. Approaches to Recruiting 'Hard-To-Reach' Populations into Re-search: A Review of the Literature.

    2011-01-01

    'Hard-to-reach' is a term used to describe those sub-groups of the population that may be difficult to reach or involve in research or public health programmes. Application of a single term to call these sub-sections of populations implies a homogeneity within distinct groups, which does not necessarily exist. Different sampling techniques were introduced so far to recruit hard-to-reach populations. In this article, we have reviewed a range of ap-proaches that have been used to widen participation in studies. We performed a Pubmed and Google search for relevant English language articles using the keywords and phrases: (hard-to-reach AND population* OR sampl*), (hidden AND population* OR sample*) and ("hard to reach" AND population* OR sample*) and a consul-tation of the retrieved articles' bibliographies to extract empirical evidence from publications that discussed or examined the use of sampling techniques to recruit hidden or hard-to-reach populations in health studies. Reviewing the literature has identified a range of techniques to recruit hard-to-reach populations, including snowball sampling, respondent-driven sampling (RDS), indigenous field worker sampling (IFWS), facility-based sampling (FBS), targeted sampling (TS), time-location (space) sampling (TLS), conventional cluster sampling (CCS) and capture re-capture sampling (CR). The degree of compliance with a study by a certain 'hard-to-reach' group de-pends on the characteristics of that group, recruitment technique used and the subject of inter-est. Irrespective of potential advantages or limitations of the recruitment techniques reviewed, their successful use depends mainly upon our knowledge about specific characteristics of the target populations. Thus in line with attempts to expand the current boundaries of our know-ledge about recruitment techniques in health studies and their applications in varying situa-tions, we should also focus on possibly all contributing factors which may have an impact on

    2016-01-01

    The Exploration Medical Capabilities (ExMC) Element of NASA's Human Research Program is charged with identifying medical capabilities that can address the challenges of prevention, diagnosis, and treatment of disease and injuries that could occur during exploration missions beyond Earth's orbit. Faced with the obstacle of access to in-flight medical care, and limitations of vehicle space, time, and communications; it is necessary to prioritize what medical consumables are manifested for the flight, and which medical conditions are addressed. Studies of astronaut health establish the incidence of common and high risk medical conditions that require medical intervention during long-duration exploration missions. In 2000, the Institute of Medicine (IOM) convened a committee of experts, Committee on Creating a Vision for Space Medicine during Travel beyond Earth Orbit, to examine the issues surrounding astronaut health and safety for long duration space missions. Two themes run throughout the committee's final report: (1) that not enough is known about the risks to human health during long-duration missions beyond Earth's orbit or about what can effectively mitigate those risks to enable humans to travel and work safely in the environment of deep space and (2) that everything reasonable should be done to gain the necessary information before humans are sent on missions of space exploration (IOM, 2001). Although several spaceflight focused pharmaceutical research studies have been conducted, few have provided sufficient data regarding medication usage or potency changes during spaceflight. The Du pharmaceutical stability study assessed medications flown on space shuttles to and from the International Space Station (ISS) from 2006 until 2008; of which some medications were still viable beyond their expiration dates (Du et al, 2011). However, as with many spaceflight studies, the small 'n' associated with this study limits the ability to draw strong conclusions from it

    Classical Ehlers-Danlos syndrome (cEDS) is a rare connective tissue disorder primarily characterized by hyperextensible skin, defective wound healing, abnormal scars, easy bruising, and generalized joint hypermobility; arterial dissections are rarely observed. Mutations in COL5A1 and COL5A2 encoding type V collagen account for more than 90% of the patients so far characterized. In addition, cEDS phenotype was reported in a small number of patients carrying the c.934C>T mutation in COL1A1 that results in an uncommon substitution of a non-glycine residue in one Gly-Xaa-Yaa repeat of the pro-α1(I)-chain p.(Arg312Cys), which leads to disturbed collagen fibrillogenesis due to delayed removal of the type I procollagen N-propeptide. This specific mutation has been associated with propensity to arterial rupture in early adulthood; indeed, in literature the individuals harboring this mutation are also referred to as "(classic) vascular-like" EDS patients. Herein, we describe a three-generation cEDS family with six adults carrying the p.(Arg312Cys) substitution, which show a variable and prevalent cutaneous involvement without any major vascular event. These data, together with those available in literature, suggest that vascular events are not a diagnostic handle to differentiate patients with the p.(Arg312Cys) COL1A1 mutation from those with COL5A1 and COL5A2 defects, and highlight that during the diagnostic process the presence of at least the p.(Arg312Cys) substitution in COL1A1 should be investigated in cEDS patients without type V collagen mutations. Nevertheless, for these patients, as well as for those affected with cEDS, a periodical vascular surveillance should be carried out together with cardiovascular risk factors monitoring. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Atmospheric dispersion calculation of the routine releases of the Triga-converted Philippine Research Reactor (PRR-1) was carried out using the computer model developed by the United States Nuclear Regulatory Commission (USNRC). It calculates average relative effluent concentration (X/Q) and average relative deposition values (D/Q) for twenty-two (22) specific distances up to 80 km from the area of concern for each sixteen compass directions. This model is based on the theory that material released to the atmosphere will be normally distributed (Gaussiah) about the plume center-line. Surface meteorological data based on a five-year monitoring period at the PAGASA Science Garden station proximate to the site were utilized in the assessment. From the result of X/Q values, annual whole body in mSv y -1 with impact to 41 Ar was evaluated. (Auth.). 9 refs.; 8 tabs.; 6 figs

    Background Burgeoning global mental health endeavors have renewed debates about cultural applicability of psychiatric categories. This study’s goal is to review strengths and limitations of literature comparing psychiatric categories with cultural concepts of distress (CCD) such as cultural syndromes, culture-bound syndromes, and idioms of distress. Methods The Systematic Assessment of Quality in Observational Research (SAQOR) was adapted based on cultural psychiatry principles to develop a Cultural Psychiatry Epidemiology version (SAQOR-CPE), which was used to rate quality of quantitative studies comparing CCD and psychiatric categories. A meta-analysis was performed for each psychiatric category. Results Forty-five studies met inclusion criteria, with 18 782 unique participants. Primary objectives of the studies included comparing CCD and psychiatric disorders (51%), assessing risk factors for CCD (18%) and instrument validation (16%). Only 27% of studies met SAQOR-CPE criteria for medium quality, with the remainder low or very low quality. Only 29% of studies employed representative samples, 53% used validated outcome measures, 44% included function assessments and 44% controlled for confounding. Meta-analyses for anxiety, depression, PTSD and somatization revealed high heterogeneity (I2 > 75%). Only general psychological distress had low heterogeneity (I2 = 8%) with a summary effect odds ratio of 5.39 (95% CI 4.71-6.17). Associations between CCD and psychiatric disorders were influenced by methodological issues, such as validation designs (β = 16.27, 95%CI 12.75-19.79) and use of CCD multi-item checklists (β = 6.10, 95%CI 1.89-10.31). Higher quality studies demonstrated weaker associations of CCD and psychiatric disorders. Conclusions Cultural concepts of distress are not inherently unamenable to epidemiological study. However, poor study quality impedes conceptual advancement and service application. With improved study design and reporting using

    In recent years, the development of more effective anticancer drugs has provided great benefits in patients' quality of life by improving both prognosis and disease-free survival. Nevertheless, the frequency and severity of side-effects, with particular reference to cardiac toxicity, have gained particular attention. The purpose of this study was to create a precise and sensitive preclinical model, able to identify early contractile dysfunction in mice treated with chemotherapy, through use of speckle-tracking echocardiography. We generated a mouse model of cardiotoxicity induced by doxorubicin. C57BL 6 mice were divided into two groups, treated for 7 days by intraperitoneal injections of placebo (vehicle) or doxorubicin (2.17 mg/kg), in order to characterize the cardiac phenotype in vivo. We demonstrated that doxorubicin caused ealy remodeling of the left ventricle: after two days of therapy, the radial, circumferential and strain rates were reduced respectively by 35%, 34%, and 39% (p-value ≤0.001). Moreover, histological analysis revealed that doxorubicin treatment increased fibrosis, cardiomyocyte diameter and apoptosis. In a murine model of doxorubicin-induced cardiac injury, we detected left ventricular dysfunction followed by alterations in conventional echocardiographic indices. Our study suggests that a change in strain could be an effective early marker of myocardial dysfunction for new anticancer treatments and, in preclinical studies, it might also be a valuable indicator for the assessment of activity of cardioprotective agents.

    A review of the literature addressing sediment transport in gravel-bed river systems and structures designed to control bed-load mobility is provided as part of Texas Department of Transportation research project 0–4695: Guidance for Design in Areas of Extreme Bed-Load Mobility. The study area comprises the western half of the Edwards Plateau in central Texas. Three primary foci of the literature review are journal articles, edited volumes, and government publications. Major themes within the body of literature include deterministic sediment transport theory and equations, development of methods to measure and analyze fluvial sediment, applications and development of theory in natural channels and flume experiments, and recommendations for river management and structural design. The literature review provides an outline and foundation for the research project to characterize extreme bed-load mobility in rivers and streams across the study area. The literature review also provides a basis upon which potential modifications to low-water stream-crossing design in the study area can be made.

    Similarities and differences across borders of Nordic countries constitute a suitable context for investigating and discussing factors related to the development of diabetes nursing research over the last three decades. The present study reviewed the entire body of contemporary diabetes nursing research literature originating in four Nordic countries: Norway, Sweden, Denmark and Iceland. Our aims were (i) to catalogue and characterise trends in research designs and research areas of these studies published over time and (ii) to describe how research involving nurses in Nordic countries has contributed to diabetes research overall. The larger goal of our analyses was to produce a comprehensive picture of this research in order to guide future studies in the field. We conducted a narrative literature review by systematically searching Medline, Medline in process, EMBASE, CINAHL, PsycINFO and Cochrane databases. These searches were limited to studies published between 1979 and 2009 that had an abstract available in English or a Nordic language. Two researchers independently selected studies for analysis, leading to the inclusion of 164 relevant publications for analysis. In summary, Nordic nurse researchers have contributed to the development of new knowledge in self-management of diabetes in childhood, adolescence and adulthood, and to some extent also in the treatment and care of diabetes foot ulcers. Future research may benefit from (i) larger nurse-led research programmes organised in networks in order to share knowledge and expertise across national groups and borders, (ii) more multidisciplinary collaborations in order to promote patient-centred care and (iii) further research directed towards improving the dissemination and implementation of research findings. Using complex intervention designs and a mix of research methods will enrich the research. © 2015 Nordic College of Caring Science.

    Gerber, Paul J

    2012-01-01

    It is now well established that learning disabilities (LD) persist into the adult years, yet despite a developing literature base in this area, there is a paucity of evidence-based research to guide research and practice. Consistent with the demands of the adult stage of development, autonomy and self-determination are crucial to quality-of-life issues to adults in general, and specifically to adults with LD. There are many areas of functioning in which adults need to adapt successfully, such as employment, family, social and emotional, daily living routines, community, and recreation and leisure. In essence, there are a myriad of challenges and outcomes as adults navigate the trials and tribulations of LD as it manifests itself into adulthood. This review of the extant evidence-based literature seeks to discover relevant knowledge that can be shared with practitioners who serve adults with LD in a variety of professional and volunteer roles, particularly in adult education settings.
