A series of human factors evaluations were undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. A team of human factors specialists, assisted by a panel of radiation oncologists, medical physicists, and radiation therapists, conducted site visits to radiation oncology departments at community hospitals, university centers, and free-standing clinics. A function and task analysis was performed initially to guide subsequent evaluations in the areas of workplace environment, system-user interfaces, procedures, training, and organizational practices. To further acquire an in-depth and up-to-date understanding of the practice of teletherapy in support of these evaluations, a systematic literature review was conducted. Factors that have a potential impact on the accuracy of treatment delivery were of primary concern. The present volume is the literature review. The volume starts with an overview of the multiphased nature of teletherapy, and then examines the requirement for precision, the increasing role of quality assurance, current conceptualizations of human error, and the role of system factors such as the workplace environment, user-system interfaces, procedures, training, and organizational practices

Case Report: A case history of unanticipated radiation-induced bilateral optic neuropathy, 18 months after induction chemotherapy and radiation therapy for a locally advanced nasopharyngeal carcinoma, is presented. Retrospective reanalysis of the radiation therapy technique, with emphasis on the doses received by the optic pathway structures, was performed. These re-calculations revealed unexpectedly high doses in the range 79 and 82 Gy (cumulative external and brachytherapy dose) at the level of the optic nerves, which explained the observed radiation injury. Conclusion: Routine implementation of computed tomography for 3D dose planning purposes is therefore advocated. Review of the current literature confirms the importance of 3D dose planning in avoiding this complication and highlights the role of MRI in establishing the diagnosis of radiation-induced optic neuropathy. (orig.) [Deutsch] Kasuistik: Ein Fallbericht mit unerwarteter strahleninduzierter beidseitiger Optikusneuropathie 18 Monate nach eingeleiteter Chemo- und Strahlentherapie wegen eines lokal fortgeschrittenen Nasopharynxkarzinoms wird praesentiert. Eine retrospektive Analyse der Radiotherapietechnik mit Berechnung der Dosisbelastung der Sehbahnstrukturen wurde durchgefuehrt. Aus dieser Berechnung wurde deutlich, dass die Komplikation durch eine unerwartet hohe Dosis in den Sehnerven (79 bis 82 Gy) verursacht wurde. Schlussfolgerung: Eine routinemaessige Durchfuehrung einer Computertomographie fuer die dreidimensionale (Dosis-)Planung wird befuerwortet. Ein Rueckblick auf die aktuelle Literatur bestaetigt die Notwendigkeit einer dreidimensionalen (Dosis-)Planung, um diese Komplikationen zu vermeiden. Die Rolle des MRI beim Nachweis der Diagnose der strahleninduzierten Optikusneuropathie ist hervorzuheben. (orig.)

Clinical, biological, histological features and treatment of oral mucositis induced by radiation therapy: a literature review

Bonan, Paulo Rogerio Ferreti; Lopes, Marcio Ajudarte; Almeida, Oslei Paes de; Alves, Fabio de Abreu

2005-01-01

The oral mucositis is a main side effect of radiotherapy on head and neck, initiating two weeks after the beginning of the treatment. It is characterized by sensation of local burning to intense pain, leading in several cases, to the interruption of the treatment. The purpose of this work is to review the main published studies that discuss the clinical, biological and histopathological features of oral mucositis induced by radiation therapy and to describe the main approaches recommended to prevent or to treat it. Although the clinical features of mucositis are intensively described in the literature, few studies address the histopathological alterations in oral mucositis and only recently, its biological processes have been investigated. The biological mechanisms involved in the radiation tissue damage have been only recently discussed and there is no consensus among treatment modalities. Yet, the progressive knowledge in the histopathology and biological characteristics of oral mucositis probably will lead to more effective in prevention and control strategies. (author)

The genetic effects of participating the irradiated males and nonirradiated females, irradiated females and nonirradiated males as well as both irradiated parents in gametes impregnation are analyzed and summarized in the literature review. The interconnection between the conditions of external radiation effect on gametogenesis of parents and the progeny effects in the embryogenesis and after the birth is traced. The sequence of change in genetic radiovulnerability of gametes at various stages of spermatogenesis and oogenesis and their combinations by participation of two irradiated parents in the gametes impregnation is shown. Some general regularities in the hereditary effects of the mammals irradiation are formulated [ru

Review of existing issues, ethics and practices in general medical research and in radiation protection research

2008-01-01

A literature review was carried out in relation to general medical research and radiation protection research. A large number of documents were found concerning the subject of ethics in general medical research. For radiation protection research, the number of documents and the information available is very limited. A review of practices in 13 European countries concerning general medical research and radiation protection research was carried out by sending a questionnaire to each country. It was found that all countries reviewed were well regulated for general medical research. For research that involves ionising radiation, the UK and Ireland are by far the most regulated countries. For other countries, there does not seem to be much information available. From the literature review and the review of practices, a number of existing ethical issues were identified and exposed, and a number of conclusions were drawn. (authors)

Retrospective analysis of eight new cases of radiation-induced sarcomas following radiotherapy for breast carcinoma and literature review. Eleven patients presenting with radiation-induced sarcoma after radiotherapy for breast cancer have been treated between 1983 and 1997 at Henri Mondor University Hospital (France). Eight of these patients respected the criteria established by Cahan et al. The others had Stewart-Treves Syndrome and were thus excluded from the analysis. Only one of the eight patients had received chemotherapy. All of the patients at the time of diagnosis of radiation-induced sarcoma were free of breast cancer recurrence. Radiation-induced sarcoma appeared with a latency period of 5 to 18 years (mean: 10.3 years). Patients' ages ranged from 39 to 88 years (mean: 57.6 years) at the time of diagnosis of sarcoma. Three sarcomas occurred in the treated breast, two in the chest wall, one in the pre-clavicular area and two in the axillary region. There were two angiosarcomas, three fibrosarcomas, one osteosarcoma, one malignant fibrous histiocytoma (MFH), and one undifferentiated sarcoma. All patients have received treatment for their sarcoma: all of them underwent surgery, one patient combined radiotherapy and chemotherapy, and three patients chemotherapy. Two patients were alive and free from disease. Six patients died (5-34 months); all six had local and/or metastatic recurrence. Radiotherapy can induce malignancies after a latent period of several years. Radiation-induced sarcomas are associated with poor overall prognosis. The treatment in most of the cases is late and ineffective, therefore careful follow-up is needed. There are still many uncertainties and questions about radiation-induced sarcomas. (authors)

Wipe sampling - review of the literature

International Nuclear Information System (INIS)

Souza, Daiane Cristini Barbosa de; Vicente, Roberto

2011-01-01

Methods for characterization of solid, non-compactable radioactive wastes contaminated in the surface are developed aiming at estimating the waste radioisotopic inventory for regulatory compliance and operational purposes. The wastes of interest here are mainly composed of plastic, metallic, or other materials parts originated in the decommissioning and maintenance operations of nuclear facilities. One way of measuring surface contamination is the indirect method of wiping the contaminated surface and counting the wipe, a common method of detecting non-fixed contamination in the radiation protection routine. The wipe sampling is an important tool in controlling the quality of the workplace in nuclear and radioactive facilities. Although radioprotection regulations establish quantitative limits, the practice in the radiation protection routine is to use wipe sampling as a qualitative measurement. To product useful quantitative results for inventorying radioactive wastes, a quantitative approach must be adopted. A previous paper presented by the authors in the last INAC Conference discussed alternative wipe materials and protocols. The method of wipe sampling underwent small changes since it started to be used but still is the object of study, as it is attested by many recent papers and patents on the subject. This article consists of a literature review. Results of a survey in the literature about wipe sampling techniques that can be applied to waste characterization are presented. (author)

2018-01-01

Digital disruption is a term/phenomenon frequently appearing in innovation management literature. However, no academic consensus exists as to what it entails; conceptual nor theoretical. We use the SLR-method (Structured Literature Review) to investigate digital disruption literature. A SLR......-study conducted in 2017 revealed some useful information on how disruption and digital disruption literature has developed over a specific period. However, this study was less representative of papers addressing digital disruption; which is the in-depth subject of this paper. To accommodate this, we intend...... to conduct a similar SLR-study assembling a body literature having digital disruption as the only common denominator...

Unilateral hypoglossal nerve atrophy as a late complication of radiation therapy of head and neck carcinoma: a report of four cases and a review of the literature on peripheral and cranial nerve damages after radiation therapy

International Nuclear Information System (INIS)

Cheng, V.S.T.; Schulz, M.D.

1975-01-01

The case histories of four patients who developed hemiatrophy of the tongue from 3 to 9 years after a course of curative radiation therapy for carcinomas of the head and neck are presented. These patients were subsequently followed from 1 1 / 2 to 6 years without local recurrence of the tumor, distant metastasis, or involvement of other cranial nerves, indicative of only a unilateral hypoglossal nerve atrophy. A review of the literature showed that peripheral and cranial nerve damages after radiation therapy have been reported for the optic nerve, hypoglossal nerve, oculomotor nerve, abducens nerve, recurrent laryngeal nerve, brachial plexus nerves, and peripheral nerves of the extremities. Review of clinical and experimental data indicated that in most cases, the damages were probably caused by extensive connective tissue fibrosis around and infiltrating the nerve trunks. Three possible types of peripheral and cranial nerve damages after radiation therapy are identified. (U.S.)

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 objective of our study was to evaluate the methodological quality of systematic reviews and meta-analyses in Radiation Oncology. A systematic literature search was conducted for all eligible systematic reviews and meta-analyses in Radiation Oncology from 1966 to 2015. Methodological characteristics were abstracted from all works that satisfied the inclusion criteria and quality was assessed using the critical appraisal tool, AMSTAR. Regression analyses were performed to determine factors associated with a higher score of quality. Following exclusion based on a priori criteria, 410 studies (157 systematic reviews and 253 meta-analyses) satisfied the inclusion criteria. Meta-analyses were found to be of fair to good quality while systematic reviews were found to be of less than fair quality. Factors associated with higher scores of quality in the multivariable analysis were including primary studies consisting of randomized control trials, performing a meta-analysis, and applying a recommended guideline related to establishing a systematic review protocol and/or reporting. Systematic reviews and meta-analyses may introduce a high risk of bias if applied to inform decision-making based on AMSTAR. We recommend that decision-makers in Radiation Oncology scrutinize the methodological quality of systematic reviews and meta-analyses prior to assessing their utility to inform evidence-based medicine and researchers adhere to methodological standards outlined in validated guidelines when embarking on a systematic review.

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.

Ionizing radiation is a well-known but little understood risk factor for lens opacities. Until recently, cataract development was considered to be a deterministic effect occurring at lens doses exceeding a threshold of 5-8 Gy. Substantial uncertainty about the level and the existence of a threshold subsists. The International Commission on Radiation Protection recently revised it to 0.5 Gy. Based on a systematic literature review of epidemiological studies on exposure to low levels of ionizing radiation and the occurrence of lens opacities, a list of criteria for new epidemiological studies was compiled, and a list of potential study populations was reviewed. Among 24 publications finally identified, six report analyses of acute exposures in atomic bomb survivors and Chernobyl liquidators, and the others report analyses of protracted exposures in occupationally, medically or accidentally exposed populations. Three studies investigated a dose threshold: in atomic bomb survivors, the best estimates were 1 Sv (95 % CI <0-0.8 Sv) regarding lensectomies; in survivors exposed as children, 0.6 Sv (90 % CI <0.0-1.2 Sv) for cortical cataract prevalence and 0.7 Sv (90 % CI 0.0-2.8 Sv) for posterior subcapsular cataract; and in Chernobyl liquidators, 0.34 Sv (95 % CI 0.19-0.68 Sv) for stage 1 cataract. Current studies are heterogeneous and inconclusive regarding the dose-response relationship. Protracted exposures and high lens doses occur in several occupational groups, for instance, in physicians performing fluoroscopy-guided interventional procedures, and in accidentally exposed populations. New studies with a good retrospective exposure assessment are feasible and should be initiated. (orig.)

Radiotherapy for management of Langerhans' cell histiocytosis. Two case reports and a literature review

2000-01-01

The use of radiotherapy in the treatment of Langerhans' cell histiocytosis was first reported in the literature in 1930 and has been proven as effective in numerous studies. We present the results of two female adults with eosinophilic granuloma of bone who underwent conventionally fractionated radiation therapy with total doses of 7x1.8 Gy and 7x2.0 Gy in four different sites. After observation periods raging from three months to six years local control of the disease was achieved in all treated locations. A review of 18 previously published studies include a total of 310 sites of eosinophilic granuloma of bone in 216 patients. It was demonstrated in 13 studies that the patients had complete relief of symptoms. An average of 94.3% had local control of the symptoms. Furthermore, in 12 studies for a total of 344 cases with involvement of other organs local control was reported in an average of 64.8% (range: 14.3-100%). Based on our own observations and on the literature review we conclude that low dose radiation therapy plays an important role in the management of localised Langerhans' cell histiocytosis. In order to minimise the risk of radiation induced neoplasms an accurate and precise radiation technique is required. (orig.) [de

Ionizing Radiation and Human Gender Proportion at Birth: A Concise Review of the Literature and A Complementary Analysis of Historical and Recent Data

2017-12-01

Full Text Available Dear Editor, This letter considers an article by Scherb et al. entitled “Ionizing radiation and the human gender proportion at birth: A concise review of the literature and a complementary analysis of historical and recent data” published in Early Human Development (DOI: http://dx.doi.org/10.1016/j.earlhumdev.2015.10.012 [1]. The authors of this challenging paper have reviewed the literature regarding the effect of exposure to ionizing radiation on gender ratio at birth. Scherb et al. have stated that above-thebackground levels of ionizing radiation may alter the gender ratio at birth: “We are of the strong opinion that gradually increasing the level of background radiation poses an increased genetic risk to humans and creature and that more research should be initiated in this respect. This has implications for the nuclear power industry, and emphasizes the importance of finding safe methods for processing and storing nuclear waste”. They also claimed that the data they presented confirm the existence of an impact of ionizing radiation on human secondary sex. This paper bears a very basic shortcoming. We know that at present, the level of natural background radiation varies on Earth at least two orders of magnitude [2]. Mortazavi et al. have previously published reports on the health effects of exposure to elevated levels of natural ionizing radiation in HBNRAs of Ramsar [2-6]. While radiation level in Ramsar is up to 260 mSv y−1 (the highest background radiation levels known among inhabited areas, up to 13 times higher than the recommended dose limit for radiation workers in Iran that is 20 mSv y−1, people living in high background radiation areas of Ramsar show no observable detrimental effect. It is worth mentioning that if a radiation dose of a few hundred mSv per year has adverse health effects and causes genetic abnormalities or an increased risk of cancer, it should be evident to the residents of these hot areas [6].

Literature survey: health effects of radiation

International Nuclear Information System (INIS)

Tveten, U.; Garder, K.

This report was originally written as a chapter of a report entitled 'Air pollution effects of electric power generation, a literature survey', written jointly by the Norwegian Institute for Air Research (NILU) and the Institutt for Atomenergi (IFA). (INIS RN242406). A survey is presented of the health effects of radiation. It has not, however, been the intention of the authors to make a complete list of all the literature relevant to this subject. The NILU/IFA report was meant as a first step towards a method of comparing the health effects of electric power generation by fission, gas and oil. Consequently information relevant to quantification of the health effects on humans has been selected. It is pointed out that quantitative information on the health effects of low radiation and dose rates, as are relevant to routine releases, does not exist for humans. The convention of linear extrapolation from higher doses and dose rates is used worldwide, but it is felt by most that the estimates are conservative. As an example of the use of the current best estimates, a calculation of normal release radiation doses is performed. (Auth.)

Mapping the literature of radiation therapy.

Science.gov (United States)

Delwiche, Frances A

2013-04-01

This study characterizes the literature of the radiation therapy profession, identifies the journals most frequently cited by authors writing in this discipline, and determines the level of coverage of these journals by major bibliographic indexes. Cited references from three discipline-specific source journals were analyzed according to the Mapping the Literature of Allied Health Project Protocol of the Nursing and Allied Health Resources Section of the Medical Library Association. Bradford's Law of Scattering was applied to all journal references to identify the most frequently cited journal titles. Journal references constituted 77.8% of the total, with books, government documents, Internet sites, and miscellaneous sources making up the remainder. Although a total of 908 journal titles were cited overall, approximately one-third of the journal citations came from just 11 journals. MEDLINE and Scopus provided the most comprehensive indexing of the journal titles in Zones 1 and 2. The source journals were indexed only by CINAHL and Scopus. The knowledgebase of radiation therapy draws heavily from the fields of oncology, radiology, medical physics, and nursing. Discipline-specific publications are not currently well covered by major indexing services, and those wishing to conduct comprehensive literature searches should search multiple resources.

Chowdhary, Ramesh; Kumari, Shail; Rao, Srinivasa B

2017-01-01

Introduction: The widespread use of cell phone in recent years has raised many questions whether their use is safe to operator who is exposed to Electromagnetic Waves (EMV). Aim To find out the effect of cell phone emitted radiations on the orofacial structures. Materials and Methods To identify suitable literature, an electronic search was performed using Medline, Pubmed and EBSCO host database in December 2016. The search was focused on effect of cell phone on orofacial structures. Among the literature available in English, the screening of the related titles and abstracts was done, and only those articles were selected for full text reading that fulfilled the inclusion criteria. Results The initial literature search resulted in 360 articles out of which only 24 articles fulfilled the inclusion criteria and were included in this systematic review. Conclusion Cell phone emitted radiations had their adverse effect on salivary glands and facial nerves. Studies showed that cell phone emitted radiations had effects on oral mucosal cells and causes changes in salivary flow rate. It was still unclear that cell phone radiations cause tumours of the salivary glands. PMID:28658925

Simulation-based education: A narrative review of the use of VERT in radiation therapy education.

Science.gov (United States)

Kane, Paul

2018-04-14

Simulation has a long history in medical and health science training and education. The literature describing this history is extensive. The role simulation plays in many health disciplines has evolved, as has the focus of the literature around it. The Virtual Environment for Radiotherapy Training (VERT) system is a relative newcomer to radiation therapy education and, similar to the literature around radiation therapy (RT) education, is still in its infancy. This narrative review sets the scene of simulation-based education within the health sciences and considers the lessons learned from published work on VERT to date. The evidence suggests that future inquiry involving VERT should explore different ways in which VERT can be used to contribute to the skillset required by the radiation therapist of tomorrow. © 2018 The Authors.

Gray literature: An important resource in systematic reviews.

Science.gov (United States)

Paez, Arsenio

2017-08-01

Systematic reviews aide the analysis and dissemination of evidence, using rigorous and transparent methods to generate empirically attained answers to focused research questions. Identifying all evidence relevant to the research questions is an essential component, and challenge, of systematic reviews. Gray literature, or evidence not published in commercial publications, can make important contributions to a systematic review. Gray literature can include academic papers, including theses and dissertations, research and committee reports, government reports, conference papers, and ongoing research, among others. It may provide data not found within commercially published literature, providing an important forum for disseminating studies with null or negative results that might not otherwise be disseminated. Gray literature may thusly reduce publication bias, increase reviews' comprehensiveness and timeliness, and foster a balanced picture of available evidence. Gray literature's diverse formats and audiences can present a significant challenge in a systematic search for evidence. However, the benefits of including gray literature may far outweigh the cost in time and resource needed to search for it, and it is important for it to be included in a systematic review or review of evidence. A carefully thought out gray literature search strategy may be an invaluable component of a systematic review. This narrative review provides guidance about the benefits of including gray literature in a systematic review, and sources for searching through gray literature. An illustrative example of a search for evidence within gray literature sources is presented to highlight the potential contributions of such a search to a systematic review. Benefits and challenges of gray literature search methods are discussed, and recommendations made. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

Background Radiation overexposure accidents are rare but can have severe long-term health consequences. Although underreporting can be an issue, some extensive literature reviews of reported radiation overexposures have been performed and constitute a sound basis for conclusions on general trends. Building further on this work, we performed a systematic review that completes previous reviews and provides new information on characteristics and trends of reported radiation accidents. Methods We searched publications and reports from MEDLINE, EMBASE, the International Atomic Energy Agency, the International Radiation Protection Association, the United Nations Scientific Committee on the Effects of Atomic Radiation, the United States Nuclear Regulatory Commission, and the Radiation Emergency Assistance Center/Training Site radiation accident registry over 1980-2013. We retrieved the reported overexposure cases, systematically extracted selected information, and performed a descriptive analysis. Results 297 out of 5189 publications and reports and 194 records from the REAC/TS registry met our eligibility criteria. From these, 634 reported radiation accidents were retrieved, involving 2390 overexposed people, of whom 190 died from their overexposure. The number of reported cases has decreased for all types of radiation use, but the medical one. 64% of retrieved overexposure cases occurred with the use of radiation therapy and fluoroscopy. Additionally, the types of reported accidents differed significantly across regions. Conclusions This review provides an updated and broader view of reported radiation overexposures. It suggests an overall decline in reported radiation overexposures over 1980-2013. The greatest share of reported overexposures occurred in the medical fields using radiation therapy and fluoroscopy; this larger number of reported overexposures accidents indicates the potential need for enhanced quality assurance programs.

Modern radiotherapy (RT) reduces the side effects at organ at risk. However, skin toxicity is still a major problem in many entities, especially head and neck cancer. Some substances like chemotherapy provide a risk of increased side effects or can induce a 'recall phenomenon' imitating acute RT-reactions months after RT. Moreover, some phototoxic drugs seem to enhance side effects of radiotherapy while others do not. We report a case of 'radiation recall dermatitis' (RRD) one year after RT as a result of taking hypericin (St. John's wort). A 65 year old man with completely resected squamous cell carcinoma of the epiglottis received an adjuvant locoregional RT up to a dose of 64.8 Gy. The patient took hypericin during and months after RT without informing the physician. During radiotherapy the patient developed unusual intensive skin reactions. Five months after RT the skin was completely bland at the first follow up. However, half a year later the patient presented erythema, but only within the area of previously irradiated skin. After local application of a steroid cream the symptoms diminished but returned after the end of steroid therapy. The anamnesis disclosed that the patient took hypericin because of depressive mood. We recommended to discontinue hypericin and the symptoms disappeared afterward. Several drugs are able to enhance skin toxicity of RT. Furthermore, the effect of RRD is well known especially for chemotherapy agents such as taxans. However, the underlying mechanisms are not known in detail so far. Moreover, it is unknown whether photosensitising drugs can also be considered to increase radiation sensitivity and whether a recall phenomenon is possible. The first report of a hypericin induced RRD and review of the literature are presented. In clinical practise many interactions between drugs and radiotherapy were not noticed and if registered not published. We recommend to ask especially for complementary or alternative

Radiation Limits for Nb3Sn Superconductors for ITER Magnets: A literature review

International Nuclear Information System (INIS)

Simon, N.J.

1995-01-01

The data base on radiation damage to Nb 3 Sn superconductors is compiled from the literature and assessed in this report. Nb 3 Sn superconductors are currently under procurement for use in ITER magnet prototypes. In contrast to the data base on insulation materials proposed for use in ITER magnets, the data base on the radiation damage of Nb 3 Sn is much more complete. Key results have often been confirmed by several groups at different institutions. The investigation of variables that influence radiation damage has also been much more complete for Nb 3 Sn than for insulators. Furthermore, in situ testing of superconducting parameters is much easier than in situ mechanical testing of insulators, and in situ testing has invariably been performed after cryogenic irradiation of Nb 3 Sn. However, in recent years, Nb 3 Sn testing has also suffered from the lack of 4-K irradiation facilities. Just as new processing methods to obtain more economical Nb 3 Sn conductor products in large quantity were being developed, cryogenic irradiation sources were being phased out. Therefore, this brief introductory section presents some basic information on the properties and structure of Nb 3 Sn superconducting composites and the distinctions between different fabrication processes. This provides a background to assess the adequacy of the current cryogenic data base on radiation damage, Also, since synergistic effects of strain and irradiation have recently been investigated, a brief discussion of the effects of strain on Nb 3 Sn properties is included in this introduction

2012-11-01

Purpose: To provide an overview and a critical appraisal of systematic reviews (SRs) of published interventions for the prevention/management of radiation dermatitis. Methods and Materials: We searched Medline, CINAHL, Embase, and the Cochrane Library. We also manually searched through individual reference lists of potentially eligible articles and a number of key journals in the topic area. Two authors screened all potential articles and included eligible SRs. Two authors critically appraised and extracted key findings from the included reviews using AMSTAR (the measurement tool for 'assessment of multiple systematic reviews'). Results: Of 1837 potential titles, 6 SRs were included. A number of interventions have been reported to be potentially beneficial for managing radiation dermatitis. Interventions evaluated in these reviews included skin care advice, steroidal/nonsteroidal topical agents, systemic therapies, modes of radiation delivery, and dressings. However, all the included SRs reported that there is insufficient evidence supporting any single effective intervention. The methodological quality of the included studies varied, and methodological shortfalls in these reviews might create biases to the overall results or recommendations for clinical practice. Conclusions: An up-to-date high-quality SR in the prevention/management of radiation dermatitis is needed to guide practice and direction for future research. We recommend that clinicians or guideline developers critically evaluate the information of SRs in their decision making.

Vanhoudt, Nathalie; Vandenhove, Hildegarde; Real, Almudena; Bradshaw, Clare; Stark, Karolina

2012-01-01

Studies were reviewed that investigated the combined effects of ionising radiation and other stressors on non-human biota. The aim was to determine the state of research in this area of science, and determine if a review of the literature might permit a gross generalization as to whether the combined effects of multi-stressors and radiation are fundamentally additive, synergistic or antagonistic. A multiple stressor database was established for different organism groups. Information was collected on species, stressors applied and effects evaluated. Studies were mostly laboratory based and investigated two-component mixtures. Interactions declared positive occurred in 58% of the studies, while 26% found negative interactions. Interactions were dependent on dose/concentration, on organism's life stage and exposure time and differed among endpoints. Except for one study, none of the studies predicted combined effects following Concentration Addition or Independent Action, and hence, no justified conclusions can be made about synergism or antagonism. - This review on multiple stressor studies involving radiation, highlights that most experimental designs used did not allow to deduce the nature of the interactive effects.

Palliative radiotherapy for painful bone metastases, single versus multiple fraction treatment: a literature review

International Nuclear Information System (INIS)

McKee, L.

2005-01-01

Palliative radiotherapy provides pain relief for patients with painful bone metastases. The practice among radiation oncologists as to whether a large single fraction is most effective, or whether multiple smaller fractions are preferable in providing the quickest, most durable pain relief is inconsistent. A literature review was completed to see if there is consensus about whether there is better pain response and control following single versus multiple fraction radiotherapy. The Pub Med search engine was used to find all reported studies comparing single and multiple fraction radiotherapy for painful bone metastases. Each article was reviewed according to specific criteria. A generalized conclusion was ascertained from each study and then compared. Among the studies reviewed, the consensus concluded that single fraction radiotherapy was the better choice for palliation of painful bone metastases. According to the literature reviewed, single fraction radiotherapy provides adequate pain relief with reasonable duration of pain response. (author)

Pregnancy and radiotherapy : management options for minimising risk, case series and comprehensive literature review

Luis, S. A.; Christie, D. R. H.; Peres, M. H.; Kaminski, A.

2009-01-01

Full text: This article reviews the efficacy and safety of radiotherapy in patients with cancer who are pregnant. Our review provided extended follow-up results in nine cases, presents a technical discussion on measures taken to minimise foetal radiation exposure and provides a comprehensive summary of the literature. Nine patients who received radiotherapy while pregnant are described. The clinical presentation and outcomes of these and 100 additional cases identified on a systematic literature review are presented. Comparisons of scattered radiation doses from three linear accelerators are presented. The average maternal follow-up in our series was 8.9 years with one patient having a recurrence of their astrocytoma. In terms of foetal outcome, there were one death in utero, one elective termination of pregnancy and one on which no data were available. Six children, on whom long-term follow-up (average 10.3 years) was obtainable, were in good health. Overall, there had been 109 cases of radiotherapy in pregnancy that met our search criteria with 13 adverse outcomes and a median follow-up of 37 months. Comparisons of three linear accelerators demonstrated significant differences in the amount of scattered radiation to the abdominal surface. In summary radiotherapy during pregnancy can be associated with a significant number of adverse outcomes. While it may be difficult for a patient not to attribute these effects to radiotherapy, it is also difficult to define the mechanisms by which radiotherapy would have caused them, if that were the case.

2016-01-01

The cancer is the kind of tumor that affects both humans and animals and is responsible for more deaths worldwide. In wildlife, cancer is a problem found most often in zoo animals. Thus veterinary oncologists have researched and developed therapeutic approaches to many types of cancer over the years in both curative and palliative therapies including therein the application of radiation. The basic principle of radiotherapy is the effect of ionizing radiation on the tumor cells, causing them to death. However, its application in veterinary medicine for wildlife is not much reported in the literature, especially in Brazil. This study aims to describe and compare some of radiotherapy applications in different species of wildlife looking to improve her knowledge in veterinary medicine through a brief literature review. After the descriptions and comparisons, it is concluded that despite the number of cases taken for this study, all the cases mentioned had satisfactory results using radiation therapy and all the presented cases provided relevant information that can guide future researchers in this area, thus improving knowledge of this therapy and improve the quality of life of animals.

2013-11-01

Full Text Available Objective: A systematic review of the literature was undertaken to investigate whether adjuvant radiotherapy and/or chemotherapeutics offered any additional benefit than surgery alone in the treatment of Merkel Cell Carcinoma (MCC. Methods: A PubMed, MEDLINE search was conducted between 1995-2013, to identify reported cases of surgically treated MCC followed by either observation, radiation, or chemoradiation. Patient demographics and outcomes were recorded and compared in a systematic fashion. Results: Thirty-four studies (n = 4475 were included. The median age was 73 years, median follow-up was 36 months and there was a 1.5:1 ratio of men to women. All 4475 patients had surgery, 1975 had no further treatment, 1689 received postoperative RT, and 301 received postoperative chemoRT. The most common site was face/head/neck, 47.8%. Stage 1 was the most common clinical stage at diagnosis (57%. Three-year LC was 20% [median 10%] in the observation cohort, compared to 65% [62%] with postoperative RT and 67% [75%] with postoperative chemoRT; these findings were statistically significant (P

Systematic review on physician's knowledge about radiation doses and radiation risks of computed tomography

International Nuclear Information System (INIS)

Krille, Lucian; Hammer, Gael P.; Merzenich, Hiltrud; Zeeb, Hajo

2010-01-01

Background: The frequent use of computed tomography is a major cause of the increasing medical radiation exposure of the general population. Consequently, dose reduction and radiation protection is a topic of scientific and public concern. Aim: We evaluated the available literature on physicians' knowledge regarding radiation dosages and risks due to computed tomography. Methods: A systematic review in accordance with the Cochrane and PRISMA statements was performed using eight databases. 3091 references were found. Only primary studies assessing physicians' knowledge about computed tomography were included. Results: 14 relevant articles were identified, all focussing on dose estimations for CT. Overall, the surveys showed moderate to low knowledge among physicians concerning radiation doses and the involved health risks. However, the surveys varied considerably in conduct and quality. For some countries, more than one survey was available. There was no general trend in knowledge in any country except a slight improvement of knowledge on health risks and radiation doses in two consecutive local German surveys. Conclusions: Knowledge gaps concerning radiation doses and associated health risks among physicians are evident from published research. However, knowledge on radiation doses cannot be interpreted as reliable indicator for good medical practice.

TRANSPORT THROUGH CRACKED CONCRETE: LITERATURE REVIEW

Energy Technology Data Exchange (ETDEWEB)

Langton, C.

2012-05-11

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

The article explains how and why these steps need to be kept in mind if a robust comprehensive literature search and analysis are to be achieved. The article outlines how to engage in the critiquing process and explains how the literature review needs to be assembled to generate a logical and reasoned debate to examine a topic of interest or research in more detail.

Student perceptions of a quality clinical experience: findings from the literature and their application to radiation therapy

International Nuclear Information System (INIS)

Fenton, Paul

2005-01-01

This paper seeks to provide a review of research findings into the clinical experience from the perception of students, with the aim of improving the clinical placements of radiation therapy students. Drawing on evidence from other allied health professions, the attributes of the ideal supervisor perceived by students is presented. The effect of clinical environment, departmental culture and communication with universities on student perception is also discussed. The lack of literature on radiation therapy education in the clinical setting has been highlighted and may be remedied in the future with the appointment of research radiation therapists. There is an ongoing need for the universities to assist radiation therapists in maintaining their skills in the supervision of students, perhaps through the provision of workshops and seminars. The list of attributes of the ideal supervisor extracted from the literature is extensive. It is an unrealistic expectation for a person to possess all of the characteristics, however the challenge is for supervisors to develop and exhibit as many as possible.

Summary of literature review of risk communication: Hanford Environmental Dose Reconstruction Project

International Nuclear Information System (INIS)

Byram, S.J.

1991-05-01

The Hanford Environmental Dose Reconstruction (HEDR) Project will estimate radiation exposures people may have received from radioactive materials released during past operations at the Department of Energy's Hanford Site near Richland, Washington. The project is being conducted by Pacific Northwest Laboratory (PNL) under the direction of an independent Technical Steering Panel (TSP). The Centers for Disease Control (CDC) will use HEDR dose estimates in studies to investigate a potential link between thyroid disease and historical Hanford emissions. The HEDR Project was initiated to address public concerns about the possible health impacts from past releases of radioactive materials from Hanford. The TSP recognized early in the project that special mechanisms would be required to communicate effectively to the many different concerned audiences. To identify and develop these mechanisms, the TSP issued Directive 89-7 to PNL in May 1989. The TSP directed PNL to examine methods to communicate the causes and effects of uncertainties in the dose estimates. A literature review was conducted as the first activity in response to the TSP's directive. This report presents the results of the literature review. The objective of the literature review was to identify ''key principles'' that could be applied to develop communications strategies for the project. 26 refs., 6 figs

Paediatric nasopharyngeal rhabdomyosarcoma: a case series and literature review

2010-01-01

Full text: Rhabdomyosarcoma (RMS) is the most common soft tissue tumour in children, with the head and neck region accounting for 35-40% of cases. Nasopharyngeal RMSs tend to grow rapidly and invade adjacent structures. Both the intergroup Rhabdomyosarcoma studies and the European Studies have established that the ideal management of this disease is multimodal, using a combination of surgery, chemotherapy and radiotherapy. This case series examines the role of radiotherapy in the management of paediatric nasopharyngeal RMSs, with particular reference to long-term morbidity and disease-free survival. The cases of five children with nasopharyngeal RMS were reviewed and a systematic review of the literature contained in the PubMed databases was conducted to establish 24 individually detailed cases. Management in all patients was multimodal, using a combination of chemotherapy, radiotherapy as well as surgery. External beam radiotherapy is an integral component of treatment for nasopharyngeal RMSs. With more patients surviving for longer periods, more long-term sequelae of radiotherapy have been reported. Complications include sensorineural deafness, endocrine manifestations following radiation of the pituitary gland, cranial nerve palsies, second malignancies within the radiation field, cataract formation, retinopathy and growth disturbance. Morbidity from radiotherapy may be considerable and depends on the field and dose of radiation. Current advances in radiotherapy are aimed at improving the rate of tumour control and reducing such complications. Recent improvements in imaging and conformal techniques have the potential to reduce the morbidity associated with radiotherapy in this cohort.

Bouallouche, A.; Vermeulen, C.; Cathelineau, G.

1983-01-01

A case of hyperparathyroidism in a fifty-four-year-old man, who had had cervical irradiation eighteen years earlier is reported. Review of the medical literature reveals that the first such case was described in 1975 and that approximately 20.5% of all patients with hyperparathyroidism have had irradiation to the head and/or neck (126 cases were found in the literature). In most instances, patients had irradiation before age twenty. The mean time-interval between irradiation and diagnosis of hyperparathyroidism is 37.5 years. Radiation dose was always above 200 rads. Histologic examination found 71.7% adenomas, 25% hyperplasias, and 3.3% borderline lesions. Antecedent irradiation to the neck should be considered an additional clue to the diagnosis of hyperparathyroidism [fr

Effects of ultraviolet radiation, visible light, and infrared radiation on erythema and pigmentation: a review.

The effects of ultraviolet radiation, visible light, and infrared radiation on cutaneous erythema, immediate pigment darkening, persistent pigment darkening, and delayed tanning are affected by a variety of factors. Some of these factors include the depth of cutaneous penetration of the specific wavelength, the individual skin type, and the absorption spectra of the different chromophores in the skin. UVB is an effective spectrum to induce erythema, which is followed by delayed tanning. UVA induces immediate pigment darkening, persistent pigment darkening, and delayed tanning. At high doses, UVA (primarily UVA2) can also induce erythema in individuals with skin types I-II. Visible light has been shown to induce erythema and a tanning response in dark skin, but not in fair skinned individuals. Infrared radiation produces erythema, which is probably a thermal effect. In this article we reviewed the available literature on the effects of ultraviolet radiation, visible light, and infrared radiation on the skin in regards to erythema and pigmentation. Much remains to be learned on the cutaneous effects of visible light and infrared radiation.

Radiation-induced chondrosarcomas: A case report with review of literature

Directory of Open Access Journals (Sweden)

Gupta G

2010-01-01

Full Text Available Radiation therapy has become an important component of various cancer treatments. The development of second malignancy as a result of radiation therapy is a well-known sinister complication. However, radiation-induced sarcomas (RIS are rare complications of radiation therapy. The timescale between completion of the radiotherapy and the development of a second malignancy, known as the latent period, can vary widely from as little as 5 years to 50 years later. Radiation-induced sarcomas per se are very rare and those with histomorphology of chondrosarcomas are even rarer. We report a rare case of RIS of left iliac bone in a 62-year-old lady after combined chemotherapy and external beam radiation therapy for cervical carcinoma (stage IIb. This case is being reported for its extreme rarity, vivid histology and clinical presentation.

2018-02-01

The group of passive prostheses consists of prosthetic hands and prosthetic tools. These can either be static or adjustable. Limited research and development on passive prostheses has been performed although many people use these prosthesis types. Although some publications describe passive prostheses, no recent review of the peer-reviewed literature on passive prostheses is available. Review the peer-reviewed literature on passive prostheses for replacement of the hand. Literature review. Four electronic databases were searched using a Boolean combination of relevant keywords. English-language articles relevant to the objective were selected. In all, 38 papers were included in the review. Publications on passive prosthetic hands describe their users, usage, functionality, and problems in activities of daily living. Publications on prosthetic tools mostly focus on sport, recreation, and vehicle driving. Passive hand prostheses receive little attention in prosthetic research and literature. Yet one out of three people with a limb deficiency uses this type of prosthesis. Literature indicates that passive prostheses can be improved on pulling and grasping functions. In the literature, ambiguous names are used for different types of passive prostheses. This causes confusion. We present a new and clear classification of passive prostheses. Clinical relevance This review provides information on the users of passive prosthetic hands and tools, their usage and the functionality. Passive prostheses receive very little attention and low appreciation in literature. Passive prosthetic hands and tools show to be useful to many unilateral amputees and should receive more attention and higher acceptance.

Loh, Tiffany Y; Rubin, Ashley G; Jiang, Shang I Brian

2017-01-01

Ultraviolet radiation is a well-known risk factor for basal cell carcinoma (BCC). Therefore, the high incidence of BCCs in sun-exposed areas such as the head and neck is unsurprising. However, unexpectedly, BCCs on the sun-protected dorsal foot have also been reported, and tumor occurrence here suggests that other factors besides ultraviolet radiation may play a role in BCC pathogenesis. Because only few dorsal foot BCCs have been reported, data on their clinical features and management are limited. To perform an updated review of the literature on clinical characteristics and treatment of dorsal foot BCCs. We conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal foot," "basal cell carcinoma foot," and "basal cell carcinoma toe." We identified 20 cases of dorsal foot BCCs in the literature, 17 of which had sufficient data for analysis. Only 1 case was treated with Mohs micrographic surgery. We present 8 additional cases of dorsal foot BCCs treated with Mohs micrographic surgery. Basal cell carcinomas on the dorsal foot are rare, and potential risk factors include Caucasian descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment option.

Occupational Exposure to Solar Radiation at Different Latitudes and Pterygium: A Systematic Review of the Last 10 Years of Scientific Literature

Directory of Open Access Journals (Sweden)

Alberto Modenese

2017-12-01

Full Text Available Pterygium is a chronic eye disease: among its recognized risk factors there is long-term exposure to ultraviolet (UV radiation. The Sun is the main source of UV exposure: according to the World Health Organization, the Population Attributable Fraction of pterygium due to solar radiation (SR is 42–74%. Outdoor work can deeply influence the eye exposure to solar UV rays, but, despite this, pterygium is currently not adequately considered as a possible occupational disease in this working category, at least in Europe. For this reason, we performed a systematic review of the scientific literature published in the last ten years (2008–2017 considering the role of outdoor work as a risk factor for pterygium, in order to give new support for the prevention of this UV related disease in workers. We identified 29 relevant papers. Our results show that pterygium prevalence highly increased with latitude and mean annual UV index, and outdoor work is one of the most relevant risk factors, as well as age and male sex, both in high risk and in moderate risk World areas considering the environmental UV levels. Accordingly, pterygium occurring in outdoor workers should be considered an occupational disease. Moreover, our findings clearly support the need of further research on more effective prevention of the occupational risk related to long-term solar radiation exposure of the eye.

The biological effects of ionising radiation on Crustaceans: A review

International Nuclear Information System (INIS)

Fuller, Neil; Lerebours, Adélaïde; Smith, Jim T.; Ford, Alex T.

2015-01-01

Highlights: • We comprehensively review the effects of ionising radiation in crustaceans. • Current environmental radioprotection levels found to be inadequate in some cases. • Mutation is shown to be a sensitive endpoint of radiation exposure. • Lowest observed effect dose rate varies by orders of magnitude. - Abstract: Historic approaches to radiation protection are founded on the conjecture that measures to safeguard humans are adequate to protect non-human organisms. This view is disparate with other toxicants wherein well-developed frameworks exist to minimise exposure of biota. Significant data gaps for many organisms, coupled with high profile nuclear incidents such as Chernobyl and Fukushima, have prompted the re-evaluation of our approach toward environmental radioprotection. Elucidating the impacts of radiation on biota has been identified as priority area for future research within both scientific and regulatory communities. The crustaceans are ubiquitous in aquatic ecosystems, comprising greater than 66,000 species of ecological and commercial importance. This paper aims to assess the available literature of radiation-induced effects within this subphylum and identify knowledge gaps. A literature search was conducted pertaining to radiation effects on four endpoints as stipulated by a number of regulatory bodies: mortality, morbidity, reproduction and mutation. A major finding of this review was the paucity of data regarding the effects of environmentally relevant radiation doses on crustacean biology. Extremely few studies utilising chronic exposure durations or wild populations were found across all four endpoints. The dose levels at which effects occur was found to vary by orders of magnitude thus presenting difficulties in developing phyla-specific benchmark values and reference levels for radioprotection. Based on the limited data, mutation was found to be the most sensitive endpoint of radiation exposure, with mortality the least sensitive

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.

JOB SATISFACTION OF MIDWIVES: A LITERATURE REVIEW

Directory of Open Access Journals (Sweden)

Daniela Nedvědová

2017-05-01

Full Text Available Aim: The aims of the literature review were to identify and analyze factors affecting job satisfaction of midwives. Design: A literature review. Methods: Included in the literature review were full texts of papers published in English language from 1990 to 2014. The search for relevant data was performed using the electronic databases CINAHL, Medline, Science Direct and Wiley Online Library. From a total of 43 studies found, 11were analyzed as quantitative studies that fulfilled the specified criteria. Results: Job satisfaction of midwives is affected by a lack of support from the management of healthcare facilities, low salary, understaffing, insufficient time for professional activities, work-family imbalance, high workload, physical demands, inadequate professional development, working environment, stress and low autonomy at work. Midwives showed signs of exhaustion, fatigue, hostility and depression, contributing to job turnover. Conclusion: The literature review presents the factors influencing job satisfaction of midwives. This is affected by many variable determinants, which create a feeling of job satisfaction of midwives, but can also lead to job dissatisfaction and, consequently, high turnover. Keywords: midwives, job satisfaction.

The joy at birth: an interpretive hermeneutic literature review.

Science.gov (United States)

Crowther, Susan; Smythe, Elizabeth; Spence, Deb

2014-04-01

this literature review examines the experience of joy at birth and what that joy means. The premise is that the whole of the birthing experience has not been fully explicated in the literature and that something of significance remains unexplored and unspoken. It is argued that a hermeneutic phenomenological approach to reviewing literature provides unique insights and leads to deeper understandings about birth and the experience of joy that attunes at that moment. the philosophical underpinnings informed by Heidegger and Gadamer are central to this review and therefore the process of reviewing literature hermeneutically is described. Heideggerian phenomenology is used as the method to ask the questions of the literature in order that concealed and hidden experiences of joy at birth are made visible where they are gleaned from the literature. A hermeneutic lens is used to uncover relationships within the phenomenon of joy at birth and meaning. although a vast birth literature was reviewed joy at birth was often ignored, hidden or covered over. Reviewing the literature on relationships, professional presence, place of birth, birth satisfaction studies and birth as peak and spiritual experience provides glimpses of the phenomenon 'joy at birth'. it is argued that joy at birth remains largely neglected as a phenomenon worthy of consideration. Plausible interpretations are presented that suggest that joy at birth points to something significant and meaningful. Spiritual and sacred meaning is alluded to in the papers reviewed yet the majority of papers that investigate birth leave this meaning unspoken. The review highlights a need for further thinking and questioning about birth that would direct on-going investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Science.gov (United States)

Kiarudi, Amir Hosein; Eghbal, Mohammad Jafar; Safi, Yaser; Aghdasi, Mohammad Mehdi; Fazlyab, Mahta

2015-01-01

By producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (CBCT) systems have met many of the limitations of conventional radiography. These systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. This review article comprehensively assembles all the data from literature regarding the potential applications of CBCT in endodontics. PMID:25598804

A review of radiation-induced demagnetization of permanent magnets

Science.gov (United States)

Samin, Adib J.

2018-05-01

Radiation-induced demagnetization of permanent magnets is important for a number of applications including space missions, particle accelerators and robots designed to carry out rescue missions at nuclear accidents where magnet failure can lead to serious consequences. This topic has been studied by several investigators over the past three decades and in this work, a review of the available literature is conducted and some general conclusions and trends are presented. In short, it can be gleaned that magnetism loss is dependent on the type of radiation, the energy of the incoming particle and the overall dose or fluence. Furthermore, magnetism loss also shows a dependence on the type of the irradiated magnet, the coercivity of the magnet, the demagnetizing field and the temperature of irradiation.

External review systems for radiation oncology facilities - clinical audit versus other review systems

International Nuclear Information System (INIS)

Bogusz-Czerniewicz, M.

2009-01-01

Background: Between 1996 and 1999 project team of ExPeRT, catalogued four external review systems of health care facilities in the European Union and countries associated with EU. Aim: The aim of this paper is a/ to identify and compare currently existing external review systems for radiation oncology facilities and b/ to distinguish main differences between clinical audit and other external evaluation models and c/ to identify where those models are currently used in European Union member states. Materials and Methods: Based on the literature review and the survey conducted between January and April 2007 among representatives of 67 national societies (for diagnostic radiology, radiotherapy and nuclear medicine) in European Union member states, the analysis of existing external review systems in radiation oncology was performed. Relevant information about purpose, scope and methodology of evaluation process for those systems were surveyed. Results: The response to the questionnaire was 72%. Only a few countries did not supply any reply in spite of repeated enquiries to several recipients. Six main categories of systems aiming at measuring the quality of service management and delivery were identified: professional peer review -based schemes, hospital accreditation, accreditation in terms of ISO standards, award seeking, certification by International Standards Organization, and clinical audit. Conclusions: Though the methodology and terminology of the five main external review systems differ, a constant movement towards collaboration and convergence of those models has been observed. Due to the social, political, and economical aspects of each European country, the different audit systems have been implemented either on voluntary or mandatory basis. (author)

Radiation-induced hypothyroidism in head and neck cancer patients: A systematic review

International Nuclear Information System (INIS)

Boomsma, Marjolein J.; Bijl, Hendrik P.; Langendijk, Johannes A.

2011-01-01

Purpose: To review literature on the relationship between the dose distribution in the thyroid gland and the incidence of radiation-induced hypothyroidism in adults. Material and Methods: Articles were identified through a search in MEDLINE, EMBASE and the Cochrane Library. Approximately 2449 articles were screened and selected by inclusion- and exclusion criteria. Eventually, there were five papers that fulfilled the eligibility criteria to be included in this review. Results: The sample sizes of the reviewed studies vary from 57 to 390 patients. The incidence of hypothyroidism was much higher (23-53%) than would be expected in a non-irradiated cohort. There was a large heterogeneity between the studies regarding study design, estimation of the dose to the thyroid gland and definition of endpoints. In general, the relationship between thyroid gland volume absorbing 10-70 Gy (V10-V70), mean dose (Dmean), minimal dose (Dmin), maximum dose (Dmax) and point doses with hypothyroidism were analysed. An association between dose-volume parameters and hypothyroidism was found in two studies. Conclusions: Hypothyroidism is frequently observed after radiation. Although the results suggest that higher radiation doses to the thyroid gland are associated with hypothyroidism, it was not possible to define a clear threshold radiation dose for the thyroid gland.

Response of melanoma to heat and radiation therapy--a review of the literature and experience from The Prince of Wales Hospital, Sydney.

Science.gov (United States)

Mameghan, H; Knittel, T

1988-11-07

Our review of the literature indicates that radiotherapy and/or heat therapy can provide local control of recurrent or metastatic melanoma in a large proportion of patients. This has undoubted value in the local palliation of symptoms and, in the absence of disseminated disease, can be curative. At The Prince of Wales Hospital, Sydney, we have studied the response of melanoma lesions to heat and radiation therapy and have assessed the reaction in the adjacent normal skin. Thirty-two melanoma lesions that were measurable in 12 patients received radiotherapy and heat therapy in different combinations and dose schedules (15 lesions received radiotherapy alone, six lesions received heat therapy alone, and 11 lesions received combined radiation and heat therapy). The acute normal skin reaction was compared between lesions that received single modality radiation or heat therapy and those that received the combination of heat and radiation therapy. A moderate or severe reaction developed at six of the 21 sites that were treated by a single modality, and at four of the 11 sites that received combined heat and radiation therapy (P = 0.7), and all healed within a few days. Evaluation of the melanoma response to therapy was possible only in 26 of the 32 lesions that were treated because two patients died soon after therapy and the response of their six lesions was not evaluable. A complete response occurred in 14 (54%) of 26 lesions and a partial response occurred in 10 (38%) of 26 lesions. The objective response by treatment modality was 10 of 15 lesions for radiotherapy, six of six lesions for heat therapy and eight of 11 lesions for both therapies combined. We conclude that radiotherapy and heat therapy, separately or combined, produce acceptably-low damage to normal tissue and highly-satisfactory local control of melanoma.

Cutaneous Angiosarcoma of the Foot: A Case Report and Review of the Literature

Directory of Open Access Journals (Sweden)

Sharang Tenjarla

2014-01-01

Full Text Available Primary Angiosarcoma of the skin of the foot is very rare. Angiosarcoma is typically treated with resection and wide-field postoperative radiation therapy. Chemotherapy and radiation therapy have also been used. Regardless of the treatment, the risk of local and distant relapse remains high for this disease. We present a case of an elderly patient who developed cutaneous angiosarcoma of the foot. It posed as a diagnostic dilemma at presentation. Chronic lymphedema was a possible predisposing factor. Given his age, preexisting renal dysfunction, refusal of surgery, and preference not to receive chemotherapy, the patient was ultimately treated with definitive radiotherapy. We present this case because of its rare site, unique presentation and delay in diagnosis of the condition, and attainment of an excellent response to radiation at the time of follow-up. We also review the current literature on this topic.

Systematic review of the literature on simulation in nursing education.

Norman, Jamil

2012-01-01

Simulation-based learning is an educational intervention which creates an environment that is conducive to experiential learning. Despite the prevalence of research on the influence of simulation on nursing education, there is a dearth of literature on the effectiveness of simulation-based learning. This systematic review examines literature on simulation outcomes in nursing education from the years 2000-2010. The electronic databases reviewed for the systematic review of the literature included: CINAHL Plus, Medline, Health Source: Nursing/Academic Education, Google Scholar, and Digital Dissertations and Theses through ProQuest. The MeSH search terms included "simulation outcomes measurement" and "nursing education". Seventeen studies were included in the review of the literature. The literature was categorized into three themes; internal outcomes, external outcomes, and clinical evaluation. The available literature on simulation and nursing education provides evidence that that simulation is useful in creating a learning environment which contributes to knowledge, skills, safety, and confidence. This systematic review of the literature revealed a gap in the literature pertaining to the transfer of these outcomes to the clinical setting, and lays a foundation for further research on outcomes specific to simulation and nursing education.

Simulation Modelling in Healthcare: An Umbrella Review of Systematic Literature Reviews.

Science.gov (United States)

Salleh, Syed; Thokala, Praveen; Brennan, Alan; Hughes, Ruby; Booth, Andrew

2017-09-01

Numerous studies examine simulation modelling in healthcare. These studies present a bewildering array of simulation techniques and applications, making it challenging to characterise the literature. The aim of this paper is to provide an overview of the level of activity of simulation modelling in healthcare and the key themes. We performed an umbrella review of systematic literature reviews of simulation modelling in healthcare. Searches were conducted of academic databases (JSTOR, Scopus, PubMed, IEEE, SAGE, ACM, Wiley Online Library, ScienceDirect) and grey literature sources, enhanced by citation searches. The articles were included if they performed a systematic review of simulation modelling techniques in healthcare. After quality assessment of all included articles, data were extracted on numbers of studies included in each review, types of applications, techniques used for simulation modelling, data sources and simulation software. The search strategy yielded a total of 117 potential articles. Following sifting, 37 heterogeneous reviews were included. Most reviews achieved moderate quality rating on a modified AMSTAR (A Measurement Tool used to Assess systematic Reviews) checklist. All the review articles described the types of applications used for simulation modelling; 15 reviews described techniques used for simulation modelling; three reviews described data sources used for simulation modelling; and six reviews described software used for simulation modelling. The remaining reviews either did not report or did not provide enough detail for the data to be extracted. Simulation modelling techniques have been used for a wide range of applications in healthcare, with a variety of software tools and data sources. The number of reviews published in recent years suggest an increased interest in simulation modelling in healthcare.

A Framework for Rigorously Identifying Research Gaps in Qualitative Literature Reviews

DEFF Research Database (Denmark)

Müller-Bloch, Christoph; Kranz, Johann

2015-01-01

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...

Review of bayesian statistical analysis methods for cytogenetic radiation biodosimetry, with a practical example

International Nuclear Information System (INIS)

Ainsbury, Elizabeth A.; Lloyd, David C.; Rothkamm, Kai; Vinnikov, Volodymyr A.; Maznyk, Nataliya A.; Puig, Pedro; Higueras, Manuel

2014-01-01

Classical methods of assessing the uncertainty associated with radiation doses estimated using cytogenetic techniques are now extremely well defined. However, several authors have suggested that a Bayesian approach to uncertainty estimation may be more suitable for cytogenetic data, which are inherently stochastic in nature. The Bayesian analysis framework focuses on identification of probability distributions (for yield of aberrations or estimated dose), which also means that uncertainty is an intrinsic part of the analysis, rather than an 'afterthought'. In this paper Bayesian, as well as some more advanced classical, data analysis methods for radiation cytogenetics are reviewed that have been proposed in the literature. A practical overview of Bayesian cytogenetic dose estimation is also presented, with worked examples from the literature. (authors)

Costa, Christine B; Hardan-Khalil, Kholoud; Gibbs, Kimberly

2017-12-01

The phenomenon of orthorexia nervosa (ON) has been noted by clinicians since 1996 and described in the scientific literature, and yet there is no formal recognition of ON as a psychiatric diagnosis. Review the latest available literature regarding diagnoses similarities, presentation uniqueness, assessment/assessment tools, and suggested treatments of ON. A literature search of four databases focusing on articles published between 2000 and 2016 was conducted to evaluate the status of the literature on Orthorexia. Among the 15 articles selected for this review, similarities with other psychiatric disorders emerged, confusion about use of assessment tools existed, and the lack of evidence based treatments for ON was pronounced. More research is needed to determine the prevalence of pathologically unhealthy, obsessive, "self-defined healthy," eating behaviors, and to determine if ON is a unique eating disorder or just a subset of another disorder.

Repatriation Adjustment: Literature Review

Full Text Available Expatriation is a widely studied area of research in work and organizational psychology. After expatriates accomplish their missions in host countries, they return to their countries and this process is called repatriation. Adjustment constitutes a crucial part in repatriation research. In the present literature review, research about repatriation adjustment was reviewed with the aim of defining the whole picture in this phenomenon. Present research was classified on the basis of a theoretical model of repatriation adjustment. Basic frame consisted of antecedents, adjustment, outcomes as main variables and personal characteristics/coping strategies and organizational strategies as moderating variables.

Full Text Available In social psychological literature, ideology is typically conceived as a relatively stable and organized set of general orientations that include interrelated attitudes grouped according to various sources of constraint, such as psychological disposition, general values, or ideological traditions. The paper reviews social-psychological literature on the organization of social attitudes. Research on this topic started nearly eight decades ago, inspired by the research on the structure of intellectual abilities. Since then, a large body of literature has been generated, which has not been systematically reviewed. Despite the long tradition, this literature has not resulted in proportional cumulative scientific development. The review should help improving this situation by listing the relevant studies, examining the research methodology and the main findings. The review ends with the critical summary of the man findings and methodological problems, and recommendations for the future research.

Review articles can provide valuable summaries of the ever-increasing volume of primary research in conservation biology. Where findings may influence important resource-allocation decisions in policy or practice, there is a need for a high degree of reliability when reviewing evidence. However, traditional literature reviews are susceptible to a number of biases during the identification, selection, and synthesis of included studies (e.g., publication bias, selection bias, and vote counting). Systematic reviews, pioneered in medicine and translated into conservation in 2006, address these issues through a strict methodology that aims to maximize transparency, objectivity, and repeatability. Systematic reviews will always be the gold standard for reliable synthesis of evidence. However, traditional literature reviews remain popular and will continue to be valuable where systematic reviews are not feasible. Where traditional reviews are used, lessons can be taken from systematic reviews and applied to traditional reviews in order to increase their reliability. Certain key aspects of systematic review methods that can be used in a context-specific manner in traditional reviews include focusing on mitigating bias; increasing transparency, consistency, and objectivity, and critically appraising the evidence and avoiding vote counting. In situations where conducting a full systematic review is not feasible, the proposed approach to reviewing evidence in a more systematic way can substantially improve the reliability of review findings, providing a time- and resource-efficient means of maximizing the value of traditional reviews. These methods are aimed particularly at those conducting literature reviews where systematic review is not feasible, for example, for graduate students, single reviewers, or small organizations. © 2015 Society for Conservation Biology.

Four EIS Perspectives: A literature review

DEFF Research Database (Denmark)

Pries-Heje, Jan; Svejvig, Per

A literature review of the Enterprise Information Systems literature reveals a number of recurring issues. We identify and detail four different perspectives that together categorizes the topics found. The first being a technical-rational perspective. The second being a social perspective....... The third being a more political and emergent perspective. Fourth, we identify a design-oriented perspective. We categorize the literature on EIS using these four perspectives, and for each perspective we identify core issues. Finally we discuss how the four perspectives complement each other....

Ionizing radiation and wild birds: a review

International Nuclear Information System (INIS)

Mellinger, P.J.; Schultz, V.

1975-01-01

Since the first atomic explosion, 16 July 1945 at the Trinity Site in south-central New Mexico, the impact of ionizing radiation on bird populations has been of concern to a few individuals. The proliferation of nuclear power plants has increased public concern as to possible deleterious effects of nuclear power plant operation on resident and migratory bird populations. Literature involving wild birds and ionizing radiation is not readily available, and only a few studies have been anywhere near comprehensive, with most effort directed towards monitoring radionuclide concentration in birds. The objective of the paper is to document the literature on wild birds and ionizing radiation including a brief description of pertinent papers

Groundwater: A review of the 1989 literature

International Nuclear Information System (INIS)

Miller, C.T.; Mayer, A.S.

1990-01-01

This review was prepared under the auspices of the WPCF Research Committee of the annual Literature Review issue of the Journal; because of logistical reasons it could not be published in June. However, in view of the growing importance of the subject, the review is presented here as a supplement to the June Literature Review issue that has not been through the Journal peer review process. In this review, distinctions are made between single-, two-, and three-phase systems. Single-phase systems refer to groundwater systems subjected to saturated flow conditions, whereas the two- and three-phase systems include groundwater systems subjected to unsaturated flow conditions, or conditions influenced by immiscible organic fluids such as petroleum products. Within the single-, two-, and three-phase system categories, subdivisions are made between physical, chemical, or biological processes such as hydrodynamics, sorption/desorption, chemical reactions, and biodegradation. Specialized areas such as radon and radionuclide transport, facilitated transport, and saline groundwaters also are treated separately. Rounding out this year's review, papers concerning groundwater quality monitoring, remediation, and management are discussed

Cesium and Strontium Separation Technologies Literature Review

Energy Technology Data Exchange (ETDEWEB)

T. A. Todd; T. A. Todd; J. D. Law; R. S. Herbst

2004-03-01

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

2015-01-01

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

Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).

Tire Crumb Research Study Literature Review / Gap ...

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.

State-of-the-evidence reviews: advantages and challenges of including grey literature.

Science.gov (United States)

Benzies, Karen M; Premji, Shahirose; Hayden, K Alix; Serrett, Karen

2006-01-01

Increasingly, health policy decision-makers and professionals are turning to research-based evidence to support decisions about policy and practice. Systematic reviews are useful for gathering, summarizing, and synthesizing published and unpublished research about clearly defined interventions. State-of-the-evidence reviews are broader than traditional systematic reviews and may include not only published and unpublished research, but also published and unpublished non-research literature. Decisions about whether to include this "grey literature" in a review are challenging and lead to many questions about whether the advantages outweigh the challenges. The primary purpose of this article is to describe what constitutes grey literature, and methods to locate it and assess its quality. The secondary purpose is to discuss the core issues to consider when making decisions to include grey literature in a state-of-the-evidence review. A recent state-of-the-evidence review is used as an exemplar to present advantages and challenges related to including grey literature in a review. Despite the challenges, in the exemplar, inclusion of grey literature was useful to validate the results of a research-based literature search. Decisions about whether to include grey literature in a state-of-the-evidence review are complex. A checklist to assist in decision-making was created as a tool to assist the researcher in determining whether it is advantageous to include grey literature in a review.

Radiation effects on ion exchange materials

Energy Technology Data Exchange (ETDEWEB)

Gangwer, T.E.; Goldstein, M.; Pillay, K.K.S.

1977-11-01

An extensive literature review and data compilation has been completed on the radiation-damage of ion exchange resins. The primary goal of the study has been to review the available literature on ion exchange materials used in, as well as those with potential for use in, the nuclear fuel and waste reprocessing areas. The physical and chemical properties of ion exchangers are reviewed. Experimental parameters useful in characterizing the effects of radiation on synthetic ion exchange resins are identified or defined. In compiling the diverse types of data, an effort was made to present the experimental data or experimentally based parameters in a format that would be useful for inter-comparing radiation effects on resins. When subject to radiation there are various general trends or qualitative effects displayed by the different types of resins. These radiation-trends and effects have been formulated into qualitative statements. The present day level of understanding of the behavior of resins under ionizing radiation is too limited to justify quantitative predictive modeling. The limitations and deficiencies of the literature are discussed and the experimentation needed to achieve quantitative modeling are outlined. 14 figs., 108 references.

Defining Plagiarism: A Literature Review

Directory of Open Access Journals (Sweden)

Akbar Akbar

2018-02-01

Full Text Available Plagiarism has repeatedly occurred in Indonesia, resulting in focusing on such academic misbehavior as a “central issue” in Indonesian higher education. One of the issues of addressing plagiarism in higher education is that there is a confusion of defining plagiarism. It seems that Indonesian academics had different perception when defining plagiarism. This article aims at exploring the issue of plagiarism by helping define plagiarism to address confusion among Indonesian academics. This article applies literature review by firs finding relevant articles after identifying databases for literature searching. After the collection of required articles for review, the articles were synthesized before presenting the findings. This study has explored the definition of plagiarism in the context of higher education. This research found that plagiarism is defined in the relation of criminal acts. The huge numbers of discursive features used position plagiaristic acts as an illegal deed. This study also found that cultural backgrounds and exposure to plagiarism were influential in defining plagiarism.

Integrative Literature Review: Ascertaining Discharge Readiness for Pediatrics After Anesthesia.

Science.gov (United States)

Whitley, Deborah R

2016-02-01

Unplanned hospital readmissions after the administration of general anesthesia for ambulatory procedures may contribute to loss of reimbursement and assessment of financial penalties. Pediatric patients represent a unique anesthetic risk. The purpose of this integrative literature review was to ascertain specific criteria used to evaluate discharge readiness for pediatric patients after anesthesia. This study is an integrative review of literature. An integrative literature search was conducted and included literature sources dated January 2008 to November 2013. Key words included pediatric, anesthesia, discharge, criteria, standards, assessment, recovery, postoperative, postanesthesia, scale, score, outpatient, and ambulatory. Eleven literature sources that contributed significantly to the research question were identified. Levels of evidence included three systematic reviews, one randomized controlled trial, three cohort studies, two case series, and two expert opinions. This integrative literature review revealed evidence-based discharge criteria endorsing home readiness for postanesthesia pediatric patients should incorporate consideration for physiological baselines, professional judgment with regard to infant consciousness, and professional practice standards/guidelines. Additionally, identifying and ensuring discharge to a competent adult was considered imperative. Nurses should be aware that frequently used anesthesia scoring systems originated in the 1970s, and this review was unable to locate current literature examining the reliability and validity of their use in conjunction with modern anesthesia-related health care practices.

Use of wildlife webcams - Literature review and annotated bibliography

Science.gov (United States)

Ratz, Joan M.; Conk, Shannon J.

2010-01-01

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

Effect of Exposure to Non-ionizing Radiation (Electromagnetic Fields on Human System: A Literature Review

Directory of Open Access Journals (Sweden)

Paula Rubya Souza C and acirc;mara

2014-08-01

Full Text Available The indiscriminate presence of radio base stations, which emit non-ionizing radiation (NIR, as well as the frequent use of mobile phones, can cause increased susceptibility of populations to the emergence of diseases such as cancers of the head and neck, biochemical, hematopoietic and hepatic changes, among others. Exposure to physical contamination, including NIR, has been implicated in numerous diseases, raising concerns about the widespread sources of exposure to this type of radiation. This paper reviews studies that have assessed associations between likely exposure to electromagnetic fields, such as radiofrequency transmissions, and many kinds of human diseases including cancer, as well as alerts to the current knowledge on the association between environmental exposure to NIR and the risk of development of adverse human health effects. This way, there appears to be an urgent need to reconsider exposure limits for low frequency and static magnetic fields, based on combined experimental and epidemiological research.

Jameson, Michael G.; Holloway, Lois C.; Metcalfe, Peter E.; Vial, Philip J.; Vinod, Shalini K.

2010-01-01

Full text: Inter-observer variability in anatomical contouring is the biggest contributor to uncertainty in radiation treatment planning. Contouring studies are frequently performed to investigate the differences between multiple contours on common datasets. There is, however, no widely accepted method for contour comparisons. The purpose of this study is to review the literature on contouring studies in the context of radiation oncology, with particular consideration of the contouring comparison methods they employ. A literature search, not limited by date, was conducted using Medline and Google Scholar with key words; contour, variation, delineation, inter/intra observer, uncertainty and trial dummy-run. This review includes a description of the contouring processes and contour comparison metrics used. The use of different processes and metrics according to tumour site and other factors were also investigated with limitations described. A total of 69 relevant studies were identified. The most common tumour sites were prostate (26), lung (10), head and neck cancers (8) and breast (7).The most common metric of comparison was volume used 59 times, followed by dimension and shape used 36 times, and centre of volume used 19 times. Of all 69 publications, 67 used a combination of metrics and two used only one metric for comparison. No clear relationships between tumour site or any other factors that may in Auence the contouring process and the metrics used to compare contours were observed from the literature. Further studies are needed to assess the advantages and disadvantages of each metric in various situations.

Mental health recovery: A review of the peer-reviewed published literature.

Science.gov (United States)

Jacob, Sini; Munro, Ian; Taylor, Beverley Joan; Griffiths, Debra

The concept of mental health recovery promotes collaborative partnership among consumers, carers and service providers. However views on mental health recovery are less explored among carers and service providers. The aim of this review was to analyse contemporary literature exploring views of mental health consumers, carers and service providers in relation to their understanding of the meaning of mental health recovery and factors influencing mental health recovery. The literature review questions were: How is mental health recovery and factors influencing mental health recovery viewed by consumers, carers and service providers? What are the differences and similarities in those perceptions? How can the outcomes and recommendations inform the Australian mental health practices? A review of the literature used selected electronic databases and specific search terms and supplemented with manual searching. Twenty-six studies were selected for review which included qualitative, mixed method, and quantitative approaches and a Delphi study. The findings indicated that the concept of mental health recovery is more explored among consumers and is seldom explored among carers and service providers. The studies suggested that recovery from mental illness is a multidimensional process and the concept cannot be defined in rigid terms. In order to achieve the best possible care, the stakeholders require flexible attitudes and openness to embrace the philosophy.

Gastric cancer screening, literature review

Porras Alfaro, Erika

2014-01-01

A comprehensive literature review was made of the methods of screening (pepsinogen test, gastrin-17, anti HP, SGD and Endoscopy). The review and descriptive study of the scientific literature related to the subject was conducted in the scientific databases: Pud Med, MD Consult and Medscape, from August 2013 to March 2014. 65 articles were found related to the topic. The review has included 47 items, assigned according to the criteria of inclusion and exclusion. Available methods were defined of high cost, difficult to spread, little sensitive, little specific and invasive. Endoscopy has had limitations of cost, quality, morbidity, mortality and availability. Pepsinogen tests and helicobacter pylori have helped identify the population at risk for later sift with endoscopy; but it is a very sensitive method. Endoscopy is recommended every two years in the population at risk (patients between 50 and 70 years with a family history of gastric cancer, chronic atrophic gastritis, Helicobacter pylori infection, intestinal metaplasia and dysplasia, patients with symptomatology of dyspepsia and with positive pepsinogen test) is a higher method than SGD in cost, sensitivity and specificity similar to invasive level. The training of the endoscopists should be strengthened in early gastric cancer detection since the detection depends on the quality of endoscopy [es

Radiation for skull base meningiomas: review of the literature on the approach to radiotherapy.

Science.gov (United States)

Moraes, Fabio Y; Chung, Caroline

2017-07-01

Skull base meningiomas (SBM) pose unique challenges for radiotherapy as these tumors are often in close proximity to a number of critical structures and may not be surgically addressed in many cases, leaving the question about the tumor grade and expected biological behaviour. External beam radiotherapy and radiosurgery are longstanding treatments for meningioma that are typically used as upfront primary therapy, for recurrent tumors and as adjuvant therapy following surgical resection. There is controversy regarding the optimal timing and approach for radiation therapy in various clinical settings such as the role of adjuvant radiotherapy for completely resected grade 2 tumours. Despite the use of radiotherapy for many decades, the evidence to guide optimal radiation treatment is limited largely to single institution series of EBRT, SRS and particle therapy. In this article, we review the published data to clarify the role of external beam radiotherapy, proton radiotherapy and single and multi-fraction radiosurgery for SBM. We also highlight the areas of potential research and need for clinical improvement, including the growing awareness and effort to improve cognitive function in this patient population, who typically have long life expectancy following their meningioma diagnosis.

Hardeman, Rachel R; Murphy, Katy A; Karbeah, J'Mag; Kozhimannil, Katy Backes

Although a range of factors shapes health and well-being, institutionalized racism (societal allocation of privilege based on race) plays an important role in generating inequities by race. The goal of this analysis was to review the contemporary peer-reviewed public health literature from 2002-2015 to determine whether the concept of institutionalized racism was named (ie, explicitly mentioned) and whether it was a core concept in the article. We used a systematic literature review methodology to find articles from the top 50 highest-impact journals in each of 6 categories (249 journals in total) that most closely represented the public health field, were published during 2002-2015, were US focused, were indexed in PubMed/MEDLINE and/or Ovid/MEDLINE, and mentioned terms relating to institutionalized racism in their titles or abstracts. We analyzed the content of these articles for the use of related terms and concepts. We found only 25 articles that named institutionalized racism in the title or abstract among all articles published in the public health literature during 2002-2015 in the 50 highest-impact journals and 6 categories representing the public health field in the United States. Institutionalized racism was a core concept in 16 of the 25 articles. Although institutionalized racism is recognized as a fundamental cause of health inequities, it was not often explicitly named in the titles or abstracts of articles published in the public health literature during 2002-2015. Our results highlight the need to explicitly name institutionalized racism in articles in the public health literature and to make it a central concept in inequities research. More public health research on institutionalized racism could help efforts to overcome its substantial, longstanding effects on health and well-being.

We aimed to identify the late effects of radiation exposure in pediatric cancer survivors. An integrated literature review was performed in the databases MEDLINE and LILACS and SciELO. Included were articles in Portuguese and English, published over the past 10 years, using the following keywords: “neoplasias/neoplasms” AND “radioterapia/radiotherapy” AND “radiação/radiation”. After analysis, 14 articles - published in nine well-known journals - met the inclusion criteria. The publications were divided into two categories: “Late endocrine effects” and “Late non-endocrine effects”. Considering the increased survival rates in children who had cancer, the impact of late effects of exposure to radiation during radiological examinations for diagnosis and treatment was analyzed. Childhood cancer survivors were exposed to several late effects and should be early and regularly followed up, even when exposed to low radiation doses

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.

Purpose: Despite the rising costs in radiation oncology, the impact of health economics research on radiation therapy practice analysis patterns is unclear. We performed a systematic review of cost-effectiveness analyses (CEAs) and cost-utility analyses (CUAs) to identify trends in reporting quality in the radiation oncology literature over time. Methods and Materials: A systematic review of radiation oncology economic evaluations up to 2014 was performed, using MEDLINE and EMBASE databases. The Consolidated Health Economic Evaluation Reporting Standards guideline informed data abstraction variables including study demographics, economic parameters, and methodological details. Tufts Medical Center CEA registry quality scores provided a basis for qualitative assessment of included studies. Studies were stratified by 3 time periods (1995-2004, 2005-2009, and 2010-2014). The Cochran-Armitage trend test and linear trend test were used to identify trends over time. Results: In total, 102 articles were selected for final review. Most studies were in the context of a model (61%) or clinical trial (28%). Many studies lacked a conflict of interest (COI) statement (67%), a sponsorship statement (48%), a reported study time horizon (35%), and the use of discounting (29%). There was a significant increase over time in the reporting of a COI statement (P<.001), health care payer perspective (P=.019), sensitivity analyses using multivariate (P=.043) or probabilistic methods (P=.011), incremental cost-effectiveness threshold (P<.001), secondary source utility weights (P=.010), and cost effectiveness acceptability curves (P=.049). There was a trend toward improvement in Tuft scores over time (P=.065). Conclusions: Recent reports demonstrate improved reporting rates in economic evaluations; however, there remains significant room for improvement as reporting rates are still suboptimal. As fiscal pressures rise, we will rely on economic assessments to guide our practice decisions

Radiation-induced malignant melanoma following radiation treatment for squamous cell carcinoma of the oral cavity - a case report and review of literature -

International Nuclear Information System (INIS)

Shin, Young Ju; Yang, Koang Mo; Suh, Hyun Suk

1998-01-01

Malignant melanoma of the oral cavity is rare, accounting for 1 to 8% of all malignant melanomas. The overall prognosis remains poor despite the available treatments such as radical surgery, adjuvant radiotherapy, chemotherapy and immunotherapy due to failure in early detection and tendency in early metastasis. The etiology of mucosal malignant melanoma remains unkown. However, there are few cases of malignant melanoma of the oral cavity reported in the literature, which might be related to preexisting melanosis and radiation treatment. A case with malignant melanoma developed on the same site after 6 years following irradiation for squamous cell carcinoma of the oral cavity is reported in this article

Review Of Plutonium Oxidation Literature

International Nuclear Information System (INIS)

Korinko, P.

2009-01-01

A brief review of plutonium oxidation literature was conducted. The purpose of the review was to ascertain the effect of oxidation conditions on oxide morphology to support the design and operation of the PDCF direct metal oxidation (DMO) furnace. The interest in the review was due to a new furnace design that resulted in oxide characteristics that are different than those of the original furnace. Very little of the published literature is directly relevant to the DMO furnace operation, which makes assimilation of the literature data with operating conditions and data a convoluted task. The oxidation behavior can be distilled into three regimes, a low temperature regime (RT to 350 C) with a relatively slow oxidation rate that is influenced by moisture, a moderate temperature regime (350-450 C) that is temperature dependent and relies on more or less conventional oxidation growth of a partially protective oxide scale, and high temperature oxidation (> 500 C) where the metal autocatalytically combusts and oxidizes. The particle sizes obtained from these three regimes vary with the finest being from the lowest temperature. It is surmised that the slow growth rate permits significant stress levels to be achieved that help break up the oxides. The intermediate temperatures result in a fairly compact scale that is partially protective and that grows to critical thickness prior to fracturing. The growth rate in this regime may be parabolic or paralinear, depending on the oxidation time and consequently the oxide thickness. The high temperature oxidation is invariant in quiescent or nearly quiescent conditions due to gas blanketing while it accelerates with temperature under flowing conditions. The oxide morphology will generally consist of fine particles ( 250 (micro)m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for metal temperatures in the 500-600 C range.

The mechanisms underpinning peer support: a literature review.

The employment of Peer Support Workers, who themselves have experience of significant emotional distress, can promote recovery at an individual and organisational level. While research examining the benefits of peer support within mental health services continues to grow, an understanding of how, and through what processes, these benefits are reached remains under-developed. To review the published research literature relating to the process of peer support and its underpinning mechanisms to better understand how and why it works. A scoping review of published literature identified studies relating to peer support mechanisms, processes and relationships. Studies were summarised and findings analysed. Five mechanisms were found to underpin peer support relationships (lived experience, love labour, the liminal position of the peer worker, strengths-focussed social and practical support, and the helper role). The identified mechanisms can underpin both the success and difficulties associated with peer support relationships. Further research should review a broader range of literature and clarify how these mechanisms contribute to peer support in different contexts.

Creating Value through Virtual Teams: A Current Literature Review

Directory of Open Access Journals (Sweden)

Akemi Takeoka Chatfield

2014-11-01

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

Psychogeriatric inpatient unit design: a literature review.

Science.gov (United States)

Dobrohotoff, John T; Llewellyn-Jones, Robert H

2011-03-01

In many parts of the world the provision of psychogeriatric inpatient units (PGUs) remains limited. More units will be required over coming decades given rapid population aging. Medline (1950-2010), psycINFO (1806-2009), EMBASE (1980-2009) and CINAHL (1982-2009) were searched for papers about PGU design. Selected non-peer reviewed literature such as government reports and unpublished academic dissertations were also reviewed. Data were also obtained from the literature related to general adult psychiatry inpatient units where there was limited information from studies of units designed for older people. Over 200 papers were reviewed and 130 were included. There are few good quality studies to guide the design of acute PGUs and much of the existing literature is based on opinion and anecdote or, at best, based on observational studies. Randomized controlled studies comparing different designs and assessing outcomes are virtually non-existent. Several studies have identified violence and trauma resulting from hospitalization as significant problems with current acute PGU care. Despite its limitations the available literature provides useful guidance on how PGU design can optimize patient and staff safety and improve clinical outcomes. There are significant problems with current acute PGUs, and patient mix on existing units is an important issue. Future research should examine patient and staff perceptions of different PGU ward environments, the relationship between ward design and clinical outcomes, the effects of segregating patients with challenging behaviors in dementia and the benefits or otherwise of gender segregation.

Mukherjee, Shilpi; Dhingra, Tarun; Sengupta, Anirban

2017-01-01

The Electricity Act 2003 was a landmark Act which promised to remove the maladies which afflict the Indian Power Sector and that too at a time when the sector was ridden with problems. With concepts such as open access, multiple distribution licensees, wheeling of electricity etc, the said Act intended to encourage competition which in turn was meant bring a paradigm shift in the sector. The paper undertakes a systematic literature review to find the status of review of the promising Act. More than a decade has passed since its enactment and amendments are due with the legislative body of India but none of the literature reviewed gives a comprehensive view encompassing all the objectives of the Act. Moreover, these documents study either the probable impact or the impact on a particular segment only. It has important implications for the Power sector which highlights a significant gap in literature and provides a basis on which future research can be built upon. - Highlights: • Electricity Act 2003 is a landmark in Indian power sector reform. • Systematic literature review is done to find the status of review of the Act. • Status of Electricity Act 2003 not comprehensively reviewed. • Status of the act needs to be reviewed comprehensively through actual data.

2011-07-01

This paper presents the results of a review of literature relating to knowledge transfer and exchange in healthcare. Treatment, planning and policy decisions in contemporary nursing and healthcare should be based on sound evidence wherever possible, but research knowledge remains generally underused. Knowledge transfer and exchange initiatives aim to facilitate the accessibility, application and production of evidence and may provide solutions to this challenge. This review was conducted to help inform the design and implementation of knowledge transfer and exchange activities for a large healthcare organization. Databases: ASSIA, Business Source Premier, CINAHL, PsychInfo, Medline and the Cochrane Database of Systematic Reviews. An integrative literature review was carried out including an extensive literature search. English language systematic reviews, literature reviews, primary quantitative and qualitative papers and grey literature of high relevance evaluating, describing or discussing knowledge transfer or exchange activities in healthcare were included for review (January 1990-September 2009). Thirty-three papers were reviewed (four systematic reviews, nine literature reviews, one environmental scan, nine empirical studies and ten case studies). Robust research into knowledge transfer and exchange in healthcare is limited. Analysis of a wide range of evidence indicates a number of commonly featured characteristics but further evaluation of these activities would benefit their application in facilitating evidence-based practice in nursing. © 2011 The Authors.

The role of radiation therapy in malignant pleural mesothelioma: A systematic review

International Nuclear Information System (INIS)

Ung, Yee C.; Yu, Edward; Falkson, Conrad; Haynes, Adam E.; Stys-Norman, Denise; Evans, William K.

2006-01-01

Introduction: Radiation therapy may offer patients presenting with malignant pleural mesothelioma (MPM) symptom palliation and improvements in quality of life. This systematic review will address the role of radiation therapy in the management of MPM. Methods: A thorough systematic search of the literature was conducted for published articles and conference proceedings for applicable abstracts. Relevant trials were selected and assessed. Results: Three small randomized controlled trials compared prophylactic external beam radiation therapy to no radiation therapy for patients with thoracic tracts caused by drainage tubes or diagnostic procedures. None of those trials reported any serious adverse effects. A pooled analysis found no significant reduction in the frequency of procedure tract metastases. Four non-comparative studies have shown that hemithoracic irradiation alone resulted in significant toxicity, including radiation-induced pulmonary fibrosis, radiation pneumonitis, and bronchopleural fistula, without any survival benefit. Few of the identified studies reported on symptom control, and no studies included formal measures of quality of life. Conclusion: There is limited evidence for the role of radiotherapy in the management of patients with MPM. Future studies including radiotherapy for the treatment of such patients should include formal measures of quality of life and symptom control

Neville, Christine; Dickie, Robyn; Goetz, Sandra

2014-01-01

Despite the rapid aging of the world's population, many countries are experiencing difficulty in recruiting nurses to work with older people. A literature review was conducted regarding the career preferences of undergraduate nursing students from seven different countries. The literature review has identified that gerontological nursing does not feature highly as a career goal. Notably, this has been the situation for the past decade. There is no indication that the situation is going to change at any time in the future unless some serious decisions are made at professional, health service, community, and government levels. This literature review has identified the reasons why undergraduate nurses are not choosing gerontological nursing as a career, what has been done in an attempt to address the problem, and what else may be done.

O'Connor, A M; Anderson, K M; Goodell, C K; Sargeant, J M

2014-06-01

This article is the fourth of six articles addressing systematic reviews in animal agriculture and veterinary medicine. Previous articles in the series have introduced systematic reviews, discussed study designs and hierarchies of evidence, and provided details on conducting randomized controlled trials, a common design for use in systematic reviews. This article describes development of a review protocol and the first two steps in a systematic review: formulating a review question, and searching the literature for relevant research. The emphasis is on systematic reviews of questions related to interventions. The review protocol is developed prior to conducting the review and specifies the plan for the conduct of the review, identifies the roles and responsibilities of the review team and provides structured definitions related to the review question. For intervention questions, the review question should be defined by the PICO components: population, intervention, comparison and outcome(s). The literature search is designed to identify all potentially relevant original research that may address the question. Search terms related to some or all of the PICO components are entered into literature databases, and searches for unpublished literature also are conducted. All steps of the literature search are documented to provide transparent reporting of the process. © 2014 Blackwell Verlag GmbH.

Basal Cell Carcinoma of the Dorsal Hand: An Update and Comprehensive Review of the Literature.

Science.gov (United States)

Loh, Tiffany Y; Rubin, Ashley G; Brian Jiang, Shang I

2016-04-01

Excessive ultraviolet radiation (UVR) exposure is the primary predisposing factor for basal cell carcinoma (BCC). However, surprisingly, BCCs occur very rarely on the dorsal hand, which is subject to intense sun exposure, and their infrequent presentation in this location suggests that other factors besides UVR may play a role in BCC pathogenesis. Because dorsal hand BCCs are uncommon, knowledge of their characteristics is limited, and more data are needed to describe their clinical presentation and treatment. To perform an updated review of the literature on the management of dorsal hand BCCs. The authors conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal hand," "basal cell carcinoma hand," and "basal cell carcinoma finger," and "basal cell carcinoma thumb." The authors identified 176 cases of dorsal hand BCCs in the literature, 120 of which had sufficient data for analysis. Only 4 cases were treated with Mohs micrographic surgery (MMS). The authors present 14 additional cases of dorsal hand BCCs treated with MMS. Basal cell carcinomas on the dorsal hand occur infrequently, and potential risk factors include being a male of white descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment method.

The future of manned space flight depends on an analysis of the numerous potential risks of travel into deep space. Currently no radiation dose limits have been established for these exploratory missions. To set these standards more information is needed about potential acute and late effects on human physiology from appropriate radiation exposure scenarios, including pertinent radiation types and dose rates. Cancer risks have long been considered the most serious late effect from chronic daily relatively low-dose exposures to the complex space radiation environment. However, other late effects from space radiation exposure scenarios are under study in ground-based accelerator facilities and have revealed some unique particle radiation effects not observed with conventional radiations. A comprehensive review of pertinent literature that considers tissue effects of radiation leading to functional detriments in specific organ systems has recently been published (NCRP National Council on Radiation Protection and Measurements, Information Needed to Make Radiation Protection Recommendations for Space Missions Beyond Low-Earth Orbit, Report 153, Bethesda, MD, 2006). This paper highlights the review of two non-cancer concerns from this report: cardiovascular and immunological effects.

Literature Review on Modeling Cyber Networks and Evaluating Cyber Risks.

Energy Technology Data Exchange (ETDEWEB)

Kelic, Andjelka; Campbell, Philip L

2018-04-01

The National Infrastructure Simulations and Analysis Center (NISAC) conducted a literature review on modeling cyber networks and evaluating cyber risks. The literature review explores where modeling is used in the cyber regime and ways that consequence and risk are evaluated. The relevant literature clusters in three different spaces: network security, cyber-physical, and mission assurance. In all approaches, some form of modeling is utilized at varying levels of detail, while the ability to understand consequence varies, as do interpretations of risk. This document summarizes the different literature viewpoints and explores their applicability to securing enterprise networks.

Literature reviews are an essential step in the research process and are included in all empirical and review articles. Electronic databases are commonly used to gather this literature. However, several factors can affect the extent to which relevant articles are retrieved, influencing future research and conclusions drawn. The current project examined articles obtained by comparable search strategies in two electronic archives using an exemplar search to illustrate factors that authors should consider when designing their own search strategies. Specifically, literature searches were conducted in PsycINFO and PubMed targeting review articles on two exemplar disorders (bipolar disorder and attention deficit/hyperactivity disorder) and issues of classification and/or differential diagnosis. Articles were coded for relevance and characteristics of article content. The two search engines yielded significantly different proportions of relevant articles overall and by disorder. Keywords differed across search engines for the relevant articles identified. Based on these results, it is recommended that when gathering literature for review papers, multiple search engines should be used, and search syntax and strategies be tailored to the unique capabilities of particular engines. For meta-analyses and systematic reviews, authors may consider reporting the extent to which different archives or sources yielded relevant articles for their particular review.

The role of chemotherapy and radiation in the management of biliary cancer: a review of the literature

International Nuclear Information System (INIS)

Raderer, M.; Pruckmayer, M.; Hejna, M.

1998-01-01

Carcinoma of the biliary tract is a rare tumour. To date, there is no therapeutic measure with curative potential apart from surgical intervention. Thus, patients with advanced, i.e. unresectable or metastatic disease, face a dismal prognosis. They present a difficult problem to clinicians as to whether to choose a strictly supportive approach or to expose patients to the side-effects of a potentially ineffective treatment. The objective of this article is to review briefly the clinical trials available in the current literature utilising non-surgical oncological treatment (radiotherapy and chemotherapy) either in patients with advanced, i.e. locally inoperable or metastatic cancer of the biliary tract or as an adjunct to surgery. From 65 studies identified, there seems to be no standard therapy for advanced biliary cancer. Despite anecdotal reports of symptomatic palliation and survival advantages, most studies involved only a small number of patients and were performed in a phase II approach. In addition, the benefit of adjuvant treatment remains largely unproven. No clear trend in favour of radiation therapy could be seen when the studies included a control group. In addition, the only randomised chemotherapeutic series seemed to suggest a benefit of treatment in advanced disease, but due to the small number of patients included, definitive evidence from large, randomised series concerning the benefit of non-surgical oncological intervention as compared with supportive care is still lacking. Patients with advanced biliary tract cancer should be offered the opportunity to participate in clinical trials. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

Cycling biomechanics: a literature review.

Wozniak Timmer, C A

1991-01-01

Submitted in partial fulfillment for a Master of Science degree at the University of Pittsburgh, School of Health Related Professions, Pittsburgh, PA 1.5213 This review of current literature on cycling biomechanics emphasizes lower extremity muscle actions and joint excursions, seat height, pedal position, pedaling rate, force application, and pedaling symmetry. Guidelines are discussed for optimal seat height, pedal position, and pedaling rate. Force application in the power and recovery phases of cycling and the relationship of force application to pedaling symmetry are discussed. The need for a biomechanical approach to cycling exists since a great deal of the literature is primarily physiologic in nature. The purpose of this review is to make cyclists and their advisors aware of the biomechanics of cycling and guidelines to follow. This approach is also important because cycling is a very common form of exercise prescribed by physical therapists for clinic or home programs. Biomechanical aspects of cycling should be considered by cyclists at any level of participation and by physical therapists in order for goal-oriented, efficient cycling to occur.

Central review of radiation therapy (RT) delivery within multicenter clinical trials was initiated in the early 1970s in the United States. Early quality assurance publications often focused on metrics related to process, logistics, and timing. Our objective was to review the available evidence supporting correlation of RT quality with clinical outcomes within cooperative group trials. A MEDLINE search was performed to identify multicenter studies that described central subjective assessment of RT protocol compliance (quality). Data abstracted included method of central review, definition of deviations, and clinical outcomes. Seventeen multicenter studies (1980-2012) were identified, plus one Patterns of Care Study. Disease sites were hematologic, head and neck, lung, breast, and pancreas. Between 0 and 97% of treatment plans received an overall grade of acceptable. In 7 trials, failure rates were significantly higher after inadequate versus adequate RT. Five of 9 and 2 of 5 trials reported significantly worse overall and progression-free survival after poor-quality RT, respectively. One reported a significant correlation, and 2 reported nonsignificant trends toward increased toxicity with noncompliant RT. Although more data are required, protocol-compliant RT may decrease failure rates and increase overall survival and likely contributes to the ability of collected data to answer the central trial question.

Evaluating trauma nursing education: An integrative literature review.

Science.gov (United States)

Ding, Min; Metcalfe, Helene; Gallagher, Olivia; Hamdorf, Jeffrey M

2016-09-01

A review of the current literature evaluating trauma nursing education. A variety of trauma nursing courses exist, to educate nurses working in trauma settings, and to maintain their continuing professional development. Despite an increase in the number of courses delivered, there appears to be a lack of evidence to demonstrate the effectiveness of trauma nursing education and in particular the justification for this resource allocation. Integrative literature review. A search of international literature on trauma nursing education evaluation published in English from 1985 to 2015 was conducted through electronic databases CINAHL Plus, Google Scholar, PubMed, Austhealth, Science Citation Index Expanded (Web of Science), Sciverse Science Direct (Elsevier) & One file (Gale). Only peer reviewed journal articles identifying trauma course and trauma nursing course evaluation have been included in the selection criteria. An integrative review of both quantitative and qualitative literature guided by Whittemore and Knafl's theoretical framework using Bowling's and Pearson's validated appraisal checklists, has been conducted for three months. Only 17 studies met the inclusion criteria, including 14 on trauma course evaluation and 3 on trauma nursing course evaluation. Study findings are presented as two main themes: the historical evolution of trauma nursing education and evaluation of trauma nursing education outcomes. Trauma nursing remains in its infancy and education in this specialty is mainly led by continuing professional development courses. The shortage of evaluation studies on trauma nursing courses reflects the similar status in continuing professional development course evaluation. A trauma nursing course evaluation study will address the gap in this under researched area. Copyright © 2016 Elsevier Ltd. All rights reserved.

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

Management of skin toxicity during radiation therapy: a review of the evidence

International Nuclear Information System (INIS)

Kumar, S.; Juresic, E.; Barton, M.; Shafiq, J.

2010-01-01

Acute skin toxicity occurs in the majority of the patients undergoing radical radiotherapy. While a variety of topical agents and dressing are used to ameliorate side effects, there is minimal evidence to support their use. The aims of this study were to systematically review evidence on acute skin toxicity management and to assess the current practices in ANZ. A systematic review of the literature was conducted on studies published between 1980 and 2008. A meta-analysis was performed on articles on clinical trials reporting grade II or greater toxicity. Analyses were divided into breast (the most common site) and other sites. A survey of Radiation Oncology departments across ANZ was conducted to identify patterns of practices and compare these with the published evidence. Twenty-nine articles were reviewed. Only seven articles demonstrated statistically significant results for management of side-effects. These were for topical corticosteroids, hyaluronic acid, sucralfate, calendula, Cavilon cream (3M, St Paul, Minnesota, USA) and silver leaf dressing. Meta-analysis demonstrated statistical significance for the prophylactic use of topical agents in the management acute toxicity. The survey of departments had a low response rate but demonstrated variation in skin care practices across ANZ. A considerable number of these practices were based only on anecdotal evidence. Lack of evidence in the literature for the care of radiation skin reactions was associated with variation in practice. Only a limited number of studies have demonstrated a significant benefit of specific topical agents. There is a need for objective and prospective recording of skin toxicity to collect meaningful comparative data on which to base recommendations for practice.

Effectiveness of biplane angiography compared to monoplane angiography for vascular neuro-interventions: a systematic review of the literature.

Science.gov (United States)

Bellemare, C A; Poder, T G

2017-07-01

To compare biplane technology to monoplane technology for vascular neuro-intervention. A systematic review of the literature in MEDLINE (via PubMed), Scopus, and ScienceDirect was conducted without date or language restrictions. The Downs and Black quality-assessment checklist was used. The findings of this systematic review were combined with local and Canadian data. The nine articles selected for analysis had a very low level of evidence. The studies report that the biplane system appears to reduce ionising radiation and medical complications as well as shorten procedure time. Most major hospitals in Canada use the biplane system. The biplane system could improve the operator's confidence, which could translate into reduced risk, especially for more complex procedures. The superiority of the biplane system cannot be scientifically proven based on the data in the literature. Nevertheless, given the advantages that a biplane system can provide in terms of safety, quality of care, support to university teaching programmes based on best practices, enhanced capability in performing complex procedures, this technology should be implemented with a responsibility to collect outcome data to optimise the clinical protocol regarding the dose of ionising radiation delivered.

Impact of childhood chronic illnesses on siblings: a literature review.

Science.gov (United States)

O' Brien, Irene; Duffy, Anita; Nicholl, Honor

Childhood illness can have a significant impact on families, particularly on the ill child's siblings. There is a dearth of published literature focusing on the needs of siblings of ill children. This literature review aims to provide an overview of the current healthcare literature in relation to the impact of childhood chronic illness or disability on siblings. A literature review was undertaken by searching the databases CINAHL, PsycINFO, ProQuest and Cochrane Library for relevant articles in English using the search terms: 'siblings', 'chronic illness', 'disability', 'cancer', 'sibling relations', 'sibling adjustment', 'coping', 'family-centred care', 'sibling interventions', 'camps', 'autism', 'Down's syndrome'. Seventeen research studies in total were reviewed. This review focuses on three sibling groups related to children suffering from autism, cancer and Down's syndrome, and are discussed under the following headings: sibling adjustment; family functioning and sibling's coping resources; and intervention programmes. The literature revealed that siblings of children with Down's syndrome were well adjusted to living with their brother or sister. However, there was conflicting information on the adjustment of siblings of children with cancer and autism. An awareness of the harmful effect that living with childhood illness and disability can have on some siblings is essential to enable healthcare professionals to provide supportive interventions to protect siblings' physical and emotional wellbeing.

Work motivation in health care: a scoping literature review.

Perreira, Tyrone A; Innis, Jennifer; Berta, Whitney

2016-12-01

The aim of this scoping literature review was to examine and summarize the factors, context, and processes that influence work motivation of health care workers. A scoping literature review was done to answer the question: What is known from the existing empirical literature about factors, context, and processes that influence work motivation of health care workers? This scoping review used the Arksey and O'Malley framework to describe and summarize findings. Inclusion and exclusion criteria were developed to screen studies. Relevant studies published between January 2005 and May 2016 were identified using five electronic databases. Study abstracts were screened for eligibility by two reviewers. Following this screening process, full-text articles were reviewed to determine the eligibility of the studies. Eligible studies were then evaluated by coding findings with descriptive labels to distinguish elements that appeared pertinent to this review. Coding was used to form groups, and these groups led to the development of themes. Twenty-five studies met the eligibility criteria for this literature review. The themes identified were work performance, organizational justice, pay, status, personal characteristics, work relationships (including bullying), autonomy, organizational identification, training, and meaningfulness of work. Most of the research involved the use of surveys. There is a need for more qualitative research and for the use of case studies to examine work motivation in health care organizations. All of the studies were cross-sectional. Longitudinal research would provide insight into how work motivation changes, and how it can be influenced and shaped. Several implications for practice were identified. There is a need to ensure that health care workers have access to training opportunities, and that autonomy is optimized. To improve work motivation, there is a need to address bullying and hostile behaviours in the workplace. Addressing the factors that

Defining resilience: A preliminary integrative literature review

Science.gov (United States)

Wilt, Bonnie; Long, Suzanna K.; Shoberg, Thomas G.

2016-01-01

The term “resilience” is ubiquitous in technical literature; it appears in numerous forms, such as resilience, resiliency, or resilient, and each use may have a different definition depending on the interpretation of the writer. This creates difficulties in understanding what is meant by ‘resilience’ in any given use case, especially in discussions of interdisciplinary research. To better understand this problem, this research constructs a preliminary integrative literature review to map different definitions, applications and calculation methods of resilience invoked within critical infrastructure applications. The preliminary review uses a State-of-the-Art Matrix (SAM) analysis to characterize differences in definition across disciplines and between regions. Qualifying the various usages of resilience will produce a greater precision in the literature and a deeper insight into types of data required for its evaluation, particularly with respect to critical infrastructure calculations and how such data may be analyzed. Results from this SAM analysis will create a framework of key concepts as part of the most common applications for “resilient critical infrastructure” modeling.

2016-01-01

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

Literature review of thermal and radiation performance parameters for high-temperature, uranium dioxide fueled cermet materials

International Nuclear Information System (INIS)

Haertling, C.; Hanrahan, R.J.

2007-01-01

High-temperature fissile-fueled cermet literature was reviewed. Data are presented primarily for the W-UO 2 as this was the system most frequently studied; other reviewed systems include cermets with Mo, Re, or alloys as a matrix. Failure mechanisms for the cermets are typically degradation of mechanical integrity and loss of fuel. Mechanical failure can occur through stresses produced from dissimilar expansion coefficients, voids created from diffusion of dissimilar materials or formation of metal hydride and subsequent volume expansion. Fuel loss failure can occur by high temperature surface vaporization or by vaporization after loss of mechanical integrity. Techniques found to aid in retaining fuel include the use of coatings around UO 2 fuel particles, use of oxide stabilizers in the UO 2 , minimizing grain sizes in the metal matrix, minimizing impurities, controlling the cermet sintering atmosphere, and cladding around the cermet

Nuclear Energy Literature Review

International Nuclear Information System (INIS)

Simic, Z.; Wastin, F.

2016-01-01

In the light of five years after a major accident at the Fukushima Daiichi nuclear power plant it is interesting to make nuclear energy related literature review. There is a number of accidents related reports from all major international institutions (like the IAEA and OECD NEA) and research organizations have drawn conclusions and lessons to learn from this terrible accident. These reports are the result of expert and scientific analyses carried out during these five years and they present ideal sources for both understanding what has happened and what can be learned in order to avoid and mitigate effects of such events in the future. From a wider perspective it is also interesting to analyze the impact on research and development (R and D) activities. This literature review is performed with hope to gain some useful insights from the analysis of the volume and topics in all research activities related to the Fukushima accident and nuclear energy (NE) altogether. This kind of review should at least provide an overview of trends and provide base for better planning of future activities. This paper analyzes the published NE related research of over more than 50 years with focus on three major nuclear accidents (TMI, Chernobyl and Fukushima). It has been performed using Scopus tools and database, and mainly focuses on statistics related to the subjects, countries, keywords and type of publishing. It also analyses how responsive is nuclear energy related R and D regarding the volume and subjects, and how is that research spread among most active countries. Nuclear power accidents influence increase and change of research. Both accidents, Chernobyl and Fukushima had maximum share in all nuclear power related papers at similar yearly level (9 percent in 1991 and 12 percent in 2015 respectively). TMI peaked at the 2.5 percent share in 1982. Engineering is the most frequent subjects for TMI and cumulative NE related publishing. Medicine and environmental science subjects

The most common cause of extubation failure is blocking the airway for various reasons (pharyngeal muscle weakness residual effect -often farmacologycal-, laryngospasm, vocal cord paralysis, edema of upper respiratory tract, cervical postoperative hematoma, foreign bodies or secretions. Most cases of re-intubation occurred within 2 hours after extubation. Conclusions: The most common cause of failure after general anesthesia extubation is blocking the airway generally caused by residual neuromuscular blocking effect. Airway obstruction risk increases in airway and head and neck surgery. Difficult intubation guidlines have improved performance and reduced adverse events and similar strategies must be implemented in extubation. The procedure extubation and reintubation should be documented. Working groups airway must be multidisciplinary and include specialists in otolaryngology.

Literature search strategies for conducting knowledge-building and theory-generating qualitative systematic reviews.

To report literature search strategies for the purpose of conducting knowledge-building and theory-generating qualitative systematic reviews. Qualitative systematic reviews lie on a continuum from knowledge-building and theory-generating to aggregating and summarizing. Different types of literature searches are needed to optimally support these dissimilar reviews. Articles published between 1989-Autumn 2011. These documents were identified using a hermeneutic approach and multiple literature search strategies. Redundancy is not the sole measure of validity when conducting knowledge-building and theory-generating systematic reviews. When conducting these types of reviews, literature searches should be consistent with the goal of fully explicating concepts and the interrelationships among them. To accomplish this objective, a 'berry picking' approach is recommended along with strategies for overcoming barriers to finding qualitative research reports. To enhance integrity of knowledge-building and theory-generating systematic reviews, reviewers are urged to make literature search processes as transparent as possible, despite their complexity. This includes fully explaining and rationalizing what databases were used and how they were searched. It also means describing how literature tracking was conducted and grey literature was searched. In the end, the decision to cease searching also needs to be fully explained and rationalized. Predetermined linear search strategies are unlikely to generate search results that are adequate for purposes of conducting knowledge-building and theory-generating qualitative systematic reviews. Instead, it is recommended that iterative search strategies take shape as reviews evolve. © 2012 Blackwell Publishing Ltd.

Reflection in Medical Diagnosis: A Literature Review

OpenAIRE

Mamede, Silvia; Schmidt, Henk G.

2017-01-01

Purpose: Reflection in medical diagnosis has been said to prevent errors by minimizing flaws in clinical reasoning. This claim, however, has been much disputed. While some studies show reflective reasoning to improve diagnostic performance, others find it to add nothing. This paper presents a narrative review of the literature on reflection in medical diagnosis aimed at addressing two questions: (1) how reflective reasoning has been conceived in this literature; and (2) what is the effect of ...

Clinical education and student satisfaction: An integrative literature review

Directory of Open Access Journals (Sweden)

Karen F. Phillips, EdD, MSN, IBCLC, ICCE

2017-04-01

Full Text Available The clinical component of undergraduate clinical education is a critical area in nursing programs. Faculty shortages have made recruitment of clinical faculty and clinical teaching more challenging. As such, alternate models of clinical faculty assignments are being explored to address faculty shortages. This article contains an extensive literature review conducted to survey models of clinical education and student satisfaction with the clinical environment. The purpose of this paper is to examine student satisfaction in the clinical learning environment using articles employing the Clinical Learning Environment Inventory (CLEI along with examining the use of alternate clinical staffing models in differing levels of undergraduate nursing students. A literature search focusing on studies published between 2002 and 2015 was conducted from 5 electronic databases. Thirty-five articles were reviewed and 22 were selected for this literature review. The studies reviewed concluded that students favored a more positive and favorable clinical environment than they perceived as being actually present. A supportive clinical learning environment is of paramount importance in securing positive teaching learning outcomes. Nurse educators can apply the results of this review in order to develop and maintain quality clinical teaching and to promote a positive, student-centric, clinical learning environment.

Mucosa-associated lymphoid tissue (MALT) variant of primary rectal lymphoma: a review of the English literature.

Science.gov (United States)

Kelley, Scott R

2017-03-01

Primary rectal lymphoma (PRL) is the third most common cause of rectal cancer following adenocarcinoma (90-95 %) and carcinoid (5 %). The most common variant of PRL is the mucosa-associated lymphoid tissue (MALT) type. To date, no study has been able to recommend an optimal treatment algorithm for this rare disease. The aim of our study was to review the English literature on primary rectal MALT lymphoma. A review of the English literature was conducted to identify articles describing the MALT variant of PRL. Fifty-one cases were identified. A complete response was achieved in 12 of 19 cases treated with Helicobacter pylori eradication therapy, 5 of 6 with radiation, 2 of 4 cases with chemotherapy, 2 of 4 with endoscopic resection, 6 of 8 cases with surgical resection, and all 8 with combination therapies. Cases failing initial therapies were responsive to various second-line treatments. Two cases spontaneously regressed with observation alone. Complete regression of primary rectal MALT lymphoma was achieved using various therapeutic strategies, although the numbers of different treatment modalities are too small to draw definitive conclusions.

Brown, Angela; Crookes, Patrick; Dewing, Jan

2015-01-01

Clinical leadership and the safety, quality and efficiency of patient/client care are inextricably linked in government reports, major inquiries and the professional literature. This review explores the literature on clinical leadership development within pre-registration nursing programmes. The literature retrieved from a scoping review was evaluated to identify what is already published on the development of clinical leadership within pre-registration nursing programmes. Twenty-seven publications matched the inclusion criteria and were included in this review, 14 journal articles, one thesis and 11 chapters within one book were analysed and three themes were identified: clinical leadership; curriculum content and pedagogy. RESULTS AND MAIN OUTCOMES: This review identified a paucity of literature specifically relating to clinical leadership and pre-registration nursing programmes and what is available is inconclusive and unconvincing. Academics, curriculum development leaders and accreditation bodies have a responsibility to influence how nurses are prepared for the profession as such clinical leadership and the new graduate should be considered an area of greater importance.

Subependymomas are benign intraventricular tumors with an indolent growth pattern, which are usually asymptomatic, and most commonly occur in the fourth and lateral ventricles. When symptomatic, subependymomas often obstruct critical portions of the cerebrospinal fluid (CSF) pathway, causing hydrocephalus, and range from 3 cm to 5 cm in size. We report a case of an unusually massive subependymoma of the lateral ventricles treated with subtotal resection, ventriculoperitoneal shunt, and post-surgical radiation. The clinical course, radiographic and pathologic characteristics of this massive intraventricular subependymoma are discussed, as well as the differential diagnosis of lateral ventricular masses and a review of the literature concerning subependymomas.

Vicarious learning: a review of the literature.

Science.gov (United States)

Roberts, Debbie

2010-01-01

Experiential learning theory stresses the primacy of personal experience and the literature suggests that direct clinical experience is required in order for learning to take place. However, raw or first hand experience may not be the only mechanisms by which students engage in experiential learning. There is a growing body of literature within higher education which suggests that students are able to use another's experience to learn: vicarious learning. This literature review aims to outline vicarious learning within a nursing context. Many of the studies regarding vicarious learning are situated within Higher Education in general, however, within the United States these relate more specifically to nursing students. The literature indicates the increasing global interest in this area. This paper reveals that whilst the literature offers a number of examples illustrating how vicarious learning takes place, opinion on the role of the lecturer is divided and requires further exploration and clarification. The implications for nurse education are discussed.

Lisa A Waddell

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

Voxel anthropomorphic phantoms: review of models used for ionising radiation dosimetry

International Nuclear Information System (INIS)

Lemosquet, A.; Carlan, L. de; Clairand, I.

2003-01-01

Computational anthropomorphic phantoms have been used since the 1970's for dosimetric calculations. Realistic geometries are required for this operation, resulting in the development of ever more accurate phantoms. Voxel phantoms, consisting of a set of small-volume elements, appeared towards the end of the 1980's, and significantly improved on the original mathematical models. Voxel phantoms are models of the human body, obtained using computed tomography (CT) or magnetic resonance images (MRI). These phantoms are an extremely accurate representation of the human anatomy. This article provides a review of the literature available on the development of these phantoms and their applications in ionising radiation dosimetry. The bibliographical study has shown that there is a wide range of phantoms, covering various characteristics of the general population in terms of sex, age or morphology, and that they are used in applications relating to all aspects of ionising radiation.

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners. This year, 17,722 articles written in three languages were identified by our electronic search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Another two reviewers searched the gray literature, yielding an additional 11 articles. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles. A total of 848 articles met our inclusion criteria and underwent full review. 63% were categorized as emergency care in resource-limited settings, 23% as disaster and humanitarian response, and 14% as emergency medicine development. 21 articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed a Cohen's Kappa of 0.344. In 2017, the total number of articles identified by our search continued to increase. Studies and reviews with a focus on infectious diseases, pediatrics, and trauma represented the majority of top-scoring articles. This article is protected by copyright. All rights reserved.

Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

[PSA interest and prostatitis: literature review].

Science.gov (United States)

Bruyère, F; Amine Lakmichi, M

2013-12-01

Prostatitis is easily diagnosed but sometimes associated with PSA measurement. An increased PSA in an asymptomatic patient may be associated with antibiotic use to eliminate the inflammatory part and to confirm prostate biopsy. It seems interesting to confirm or infirm these attitudes with a systematic review of the literature We performed a literature review using the words [prostatitis], [acute prostatitis], [prostate specific antigen], [PSA], in the MEDLINE, Pubmed and AMBASE database searching for articles in French or English published in the past 20 years. PSA is not always increased during an acute prostatitis episode. An increased PSA in an asymptomatic man does not seem to be systematically correlated to prostate inflammation. Analyzing the studies, it seems inaccurate to measure PSA value during a febrile urinary infection episode in men. Systematic use of antibiotic to decrease PSA and not performing prostate biopsy is not relevant and may induce resistance to antibiotic and doesn't induce a reduction risk of having prostate biopsy. PSA is unnecessary in case of febrile urinary tract infection in men. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Purpose: The purpose of this guideline was to provide a clinical framework for the use of radiation therapy after radical prostatectomy as adjuvant or salvage therapy. Methods and Materials: A systematic literature review using PubMed, Embase, and Cochrane database was conducted to identify peer-reviewed publications relevant to the use of radiation therapy after prostatectomy. The review yielded 294 articles; these publications were used to create the evidence-based guideline statements. Additional guidance is provided as Clinical Principles when insufficient evidence existed. Results: Guideline statements are provided for patient counseling, use of radiation therapy in the adjuvant and salvage contexts, defining biochemical recurrence, and conducting a restaging evaluation. Conclusions: Physicians should offer adjuvant radiation therapy to patients with adverse pathologic findings at prostatectomy (ie, seminal vesicle invastion, positive surgical margins, extraprostatic extension) and salvage radiation therapy to patients with prostate-specific antigen (PSA) or local recurrence after prostatectomy in whom there is no evidence of distant metastatic disease. The offer of radiation therapy should be made in the context of a thoughtful discussion of possible short- and long-term side effects of radiation therapy as well as the potential benefits of preventing recurrence. The decision to administer radiation therapy should be made by the patient and the multidisciplinary treatment team with full consideration of the patient's history, values, preferences, quality of life, and functional status. The American Society for Radiation Oncology and American Urological Association websites show this guideline in its entirety, including the full literature review.

Full Text Available Objective. We aimed to systematically review the literature dealing with the epidemiology, classification, clinical course, diagnosis and treatment of thymoma. Material and methods. We reviewed retrospective and prospective randomized trials using Medline and Elibrary databases. Results. The classification system, prognostic factors, paraneoplastic syndromes and their incidence in patients with thyoma were described. The diagnostic value of computed tomography, magnetic resonance imaging and positron emission tomography was evaluated and the methods of morphologic verification were described. The main attention was paid to multimodality treatment of thymoma, including surgery and intraoperative radiotherapy. Conclusion. Thymoma is a rare tumor. The accumulation of long-term follow-up results prompted the changes in clinical management of thymoma. Predisposition to late recurrence even after radical surgery determined multimodality treatment strategies.

1979-01-01

A great deal of concern is recently being expressed relative to the playing of tackle football by adolescent Canadians. The purpose of this literature review is to try to summarize the important data from the available world literature. Very few Canadian statistics are available. Most of the data comes from United States experience. Tackle football injury is examined from various perspectives: 1. Equipment 2. Mechanisms of injury 3. Types of injury, with some emphasis on epiphyseal injury 4. Prevention 5. Comparison with other sports Although no “hard and fast” conclusion is drawn, the paper tends to show that: 1. Football is dangerous 2. Football is damaging to many body systems 3. Prevention of injury is difficult under present conditions 4. Alternate games, such as soccer and rugby seem to provide the same benefits with less catastrophic injuries

Background: Season and vitamin D are indirect and direct correlates of ultraviolet (UV) radiation and are associated with pregnancy outcomes. Further to producing vitamin D, UV has positive effects on cardiovascular and immune health that may support a role for UV directly benefitting pregnancy. Objectives: To investigate the effects of UV exposure on pregnancy; specifically fetal growth, preterm birth and hypertensive complications. Methods: We conducted a systematic review of Medline, EMBASE, DoPHER, Global Health, ProQuest Public Health, AustHealth Informit, SCOPUS and Google Scholar to identify 537 citations, 8 of which are included in this review. This review was registered on PROSPERO and a. narrative synthesis is presented following PRISMA guidance. Results: All studies were observational and assessed at high risk of bias. Higher first trimester UV was associated with and improved fetal growth and increased hypertension in pregnancy. Interpretation is limited by study design and quality. Meta-analysis was precluded by the variety of outcomes and methods. Discussion: The low number of studies and risk of bias limit the validity of any conclusions.

Background: Season and vitamin D are indirect and direct correlates of ultraviolet (UV) radiation and are associated with pregnancy outcomes. Further to producing vitamin D, UV has positive effects on cardiovascular and immune health that may support a role for UV directly benefitting pregnancy. Objectives: To investigate the effects of UV exposure on pregnancy; specifically fetal growth, preterm birth and hypertensive complications. Methods: We conducted a systematic review of Medline, EMBASE, DoPHER, Global Health, ProQuest Public Health, AustHealth Informit, SCOPUS and Google Scholar to identify 537 citations, 8 of which are included in this review. This review was registered on PROSPERO and a. narrative synthesis is presented following PRISMA guidance. Results: All studies were observational and assessed at high risk of bias. Higher first trimester UV was associated with and improved fetal growth and increased hypertension in pregnancy. Interpretation is limited by study design and quality. Meta-analysis was precluded by the variety of outcomes and methods. Discussion: The low number of studies and risk of bias limit the validity of any conclusions. Environmental health methodological issues are discussed with consideration given to design and analytical improvements to further address this reproductive environmental health question. Conclusions: The evidence for UV having benefits for pregnancy hypertension and fetal growth is limited by the methodological approaches utilized. Future epidemiological efforts should focus on improving the methods of modeling and linking widely available environmental data to reproductive health outcomes. - Highlights: • Biologically plausible pathways support an association between ultraviolet radiation (UV) and pregnancy outcomes. • This study is the first systematic review of prevailing literature on the relationship between UV and singleton pregnancy outcomes. • It focuses on both substantive findings and the

Peer review, especially prospective peer review, has been supported by professional organizations as an important element in optimal Radiation Oncology practice based on its demonstration of efficacy at detecting and preventing errors prior to patient treatment. Implementation of peer review is not without barriers, but solutions do exist to mitigate or eliminate some of those barriers. Peer review practice at our institution involves three key elements: new patient conference, treatment planning conference, and chart rounds. The treatment planning conference is an adaptation of the group consensus peer review model from radiology which utilizes a group of peers reviewing each treatment plan prior to implementation. The peer group in radiation oncology includes Radiation Oncologists, Physician Residents, Medical Physicists, Dosimetrists, and Therapists. Thus, technical and clinical aspects of each plan are evaluated simultaneously. Though peer review is held in high regard in Radiation Oncology, many barriers commonly exist preventing optimal implementation such as time intensiveness, repetition, and distraction from clinic time with patients. Through the use of automated review tools and commitment by individuals and administration in regards to staffing, scheduling, and responsibilities, these barriers have been mitigated to implement this Group Consensus Peer Review model into a Radiation Oncology Clinic. A Group Consensus Peer Review model has been implemented with strategies to address common barriers to effective and efficient peer review.

College tanning behaviors, attitudes, beliefs, and intentions: A systematic review of the literature.

Despite well-established links between exposure to ultraviolet radiation (UVR) and skin cancer, UVR-based tanning behaviors persist among college students. Understanding tanning motivations, perceptions, barriers, and demographic characteristics of this population is critical to modifying these behaviors, but is limited by variability in study design, sample size, and outcomes measured in the current literature. To help clarify the tanning behaviors of this population and provide a concise reference for future studies, this review examines existing reports to determine the comparability of tanning behaviors across multiple U.S. college populations. A systematic review of the literature was performed in July 2016 to identify studies investigating tanning behaviors among U.S. college students. Twenty-three studies met inclusion criteria. High rates of indoor tanning (IT) and outdoor tanning (OT) were found among college students. Key motivators included appearance, emotion, health perceptions, and the influence of parents, peers, and the media. Misconceptions regarding skin protection, low rates of sun protective behaviors, and tanning dependence were barriers against safe UVR exposure. Understudied demographic factors may account for variance in observed tanning behaviors, emphasizing the need for standardization efforts to consistently identify trends associated with geographical region, age, year in college, and sex. The findings presented in this review reaffirm that college students are at high risk for tanning-associated skin cancer, emphasizing the critical need for effective, targeted interventions. Improved interventions will reduce the burden of skin cancer within this group, ultimately contributing to longer, healthier lives. Copyright © 2017 Elsevier Inc. All rights reserved.

Delayed radiation necrosis is a well-known adverse event following radiotherapy for brain diseases and has been studied since the 1930s. The primary pathogenesis is thought to be the direct damage to endothelial and glial cells, particularly oligodendrocytes, which causes vascular hyalinization and demyelination. This primary pathology leads to tissue inflammation and ischemia, inducing various tissue protective responses including angiogenesis. Macrophages and lymphocytes then infiltrate the surrounding areas of necrosis, releasing inflammatory cytokines such as interleukin (IL)-1α, IL-6, and tumor necrosis factor (TNF)-α. Microglia also express these inflammatory cytokines. Reactive astrocytes play an important role in angiogenesis, expressing vascular endothelial growth factor (VEGF). Some chemokine networks, like the CXCL12/CXCR4 axis, are upregulated by tissue inflammation. Hypoxia may mediate the cell-cell interactions among reactive astrocytes, macrophages, and microglial cells around the necrotic core. Recently, bevacizumab, an anti-VEGF antibody, has demonstrated promising results as an alternative treatment for radiation necrosis. The importance of VEGF in the pathophysiology of brain radiation necrosis is being recognized. The discovery of new molecular targets could facilitate novel treatments for radiation necrosis. This literature review will focus on recent work characterizing delayed radiation necrosis in the brain.

Kulbok, Pamela A; Mitchell, Emma M; Glick, Doris F; Greiner, Doris

2012-04-24

Service learning and study abroad opportunities have become increasingly popular in nursing education in the past decade. The purpose of this systematic review was to explore existing literature concerning global health experiences in nursing education. Twenty-three empirical articles from 2003 to 2010 were reviewed, building upon existing reviews of international nursing education literature. Research on two-way exchange experiences and models for best practice were found to be lacking. While an array of countries were represented as the visiting or hosting side of the experience, few co-authors from host countries were found, particularly in literature originating from the U.S. The authors recommend that two-way exchange programs be evaluated to identify successful strategies and barriers to success. Ongoing evaluation of exchanges is necessary to ensure continued sustainable partnership and exchange in immersion experiences for nursing students.

Recently, public health has acknowledged racism as a social determinant of health. Much evidence exists on the impact of individual-level racism and discrimination, with little to no examination of racism from the standpoint of systems and structures. The purpose of this systematic literature review is to analyze the extent to which public health currently addresses systemic racism in the published literature. Utilizing the PRISMA guidelines, this review examines three widely used databases to examine published literature covering the topic as well as implications for future research and practice. A total of 85 articles were included in the review analysis after meeting study criteria. Across numerous articles, the terms racism and systemic racism are largely absent. A critical need exists for an examination of the historical impact of systemic racism on the social determinants of health and health of marginalized populations.

Duignan, M.

2011-01-01

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

2009-04-01

Many acute inpatient psychiatric wards in the UK are permanently locked, although this is contrary to the current Mental Health Act Code of Practice. To conduct a literature review of empirical articles concerning locked doors in acute psychiatric inpatient wards, an extensive literature search was performed in SAGE Journals Online, EBM Reviews, British Nursing Index, CINAHL, EMBASE Psychiatry, International Bibliography of the Social Sciences, Ovid MEDLINE, PsycINFO and Google, using the search terms 'open$', 'close$', '$lock$', 'door', 'ward', 'hospital', 'psychiatr', 'mental health', 'inpatient' and 'asylum'. A total of 11 empirical papers were included in the review. Both staff and patients reported advantages (e.g. preventing illegal substances from entering the ward and preventing patients from absconding and harming themselves or others) and disadvantages (e.g. making patients feel depressed, confined and creating extra work for staff) regarding locked doors. Locked wards were associated with increased patient aggression, poorer satisfaction with treatment and more severe symptoms. The limited literature available showed the urgent need for research to determine the real effects of locked doors in inpatient psychiatry.

The aim of this integrative literature review was to describe registered nurses' medication competence. The objectives of the literature review were to chart the need for future studies and use the results for instrument development. Nurses play a vital role in different phases of a patient's medication process and thus need adequate competence to fulfil their role. Research on nurses' level of medication competence in different competency areas has been published. However, previous studies have lacked a comprehensive or integrated definition or description of medication competence in nursing. Integrative literature review. The integrative literature review followed five stages: (1) problem identification, (2) literature search, (3) data evaluation, (4) data analysis and (5) presentation. Eligible articles were identified via systematic literature search of research and evidence-based--databases. Twenty-one studies met the selection criteria. Eleven competency areas that constitute nurses' medication competence were identified: (1) anatomy and physiology, (2) pharmacology, (3) communication, (4) interdisciplinary collaboration, (5) information seeking, (6) mathematical and medication calculation, (7) medication administration, (8) medication education, (9) assessment and evaluation, (10) documentation and (11) promoting medication safety as part of patient safety. The analysis revealed three major categories which integrate these competency areas: (1) decision making competence, (2) theoretical competence and (3) practical competence. Medication competence requires a solid knowledge base and the ability to apply that knowledge in real-life situations during often complex and dynamic patient medication processes. Decision making competence was found to be an important and integral part of a nurses' theoretical and practical competence. These main competence categories integrated all of the 11 competency areas identified in this review. It is important to determine

Concave shape with variable size target volume makes treatment planning for the breast/chest wall a challenge. Conventional techniques used for the breast/chest wall cancer treatment provided better sparing of organs at risk (OARs), with poor conformity and uniformity to the target volume. Advanced technologies such as intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) improve the target coverage at the cost of higher low dose volumes to OARs. Novel hybrid techniques present promising results in breast/chest wall irradiation in terms of target coverage as well as OARs sparing. Several published data compared these technologies for the benefit of the breast/chest wall with or without nodal volumes. The aim of this article is to review relevant data and identify the scope for further research in developing optimal treatment plan for breast/chest wall cancer treatment.

Mertz, Marcel; Strech, Daniel; Kahrass, Hannes

2017-12-19

(Semi-)systematic approaches to finding, analysing, and synthesising ethics literature on medical topics are still in their infancy. However, our recent systematic review showed that the rate of publication of such (semi-)systematic reviews has increased in the last two decades. This is not only true for reviews of empirical ethics literature, but also for reviews of normative ethics literature. In the latter case, there is currently little in the way of standards and guidance available. Therefore, the methods and reporting strategies of such reviews vary greatly. The purpose of the follow-up study we present was to obtain deeper methodological insight into the ways reviews of normative literature are actually conducted and to analyse the methods used. Our search in the PubMed, PhilPapers, and Google Scholar databases led to the identification of 183 reviews of ethics literature published between 1997 and 2015, of which 84 were identified as reviews of normative and mixed literature. Qualitative content analysis was used to extract and synthesise descriptions of search, selection, quality appraisal, analysis, and synthesis methods. We further assessed quantitatively how often certain methods (e.g. search strategies, data analysis procedures) were used by the reviews. The overall reporting quality varies among the analysed reviews and was generally poor even for major criteria regarding the search and selection of literature. For example, only 24 (29%) used a PRISMA flowchart. Also, only 55 (66%) reviews mentioned the information unit they sought to extract, and 12 (14%) stated an ethical approach as the theoretical basis for the analysis. Interpretable information on the synthesis method was given by 47 (60%); the most common methods applied were qualitative methods commonly used in social science research (83%). Reviews which fail to provide sufficient relevant information to readers have reduced methodological transparency regardless of actual methodological

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners. This year 13,890 articles written in four languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles. A total of 716 articles met our inclusion criteria and underwent full review. Fifty-nine percent were categorized as emergency care in resource-limited settings, 17% as EM development, and 24% as disaster and humanitarian response. Nineteen articles received scores of 18.5 or higher out of a maximum score of 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed Cohen's kappa of 0.441. In 2016, the total number of articles identified by our search continued to increase. The proportion of articles in each of the three categories remained stable. Studies and reviews with a focus on infectious diseases, pediatrics, and the use of ultrasound in resource-limited settings represented the majority of articles selected for final review. © 2017 The Authors.

To provide a current overview of the movement for open access to the peer review literature. Perspective. Literature review of recent advances in the open access movement with a personal viewpoint of the nuances of the movement. The open access movement is complex, with many different constituents. The idealists for the open access movement are seeking open access to the literature but also to the data that constitute the research within the manuscript. The business model of the traditional subscription journal is being scrutinized in relation to the surge in the number of open access journals. Within this environment authors should beware predatory practices. More government and funding agencies are mandating open access to their funded research. This open access movement will continue to be disruptive until a business model ensures continuity of the scientific record. A flood of open access articles that might enrich, but also might pollute or confuse, the medical literature has altered the filtering mechanism provided by the traditional peer review system. At some point there may be a shake-out, with some literature being lost in cyberspace. The open access movement is maturing and must be embraced in some format. The challenge is to establish a sustainable financial business model that will permit the use of digital technology but yet not endanger the decades-old traditional publication model and peer review system. Authors seem to be slower in adopting open access than the idealists in the movement. Copyright © 2013 Elsevier Inc. All rights reserved.

For esophageal cancer patients treated with neoadjuvant chemoradiotherapy (nCRT), restaging using F-18-fluorodeoxyglucose (FDG) positron emission tomography computed tomography (PET-CT) following nCRT can detect interval metastases, including liver metastases, in almost 10% of patients. However, in clinical practice, focal FDG liver uptake, unrelated to liver metastases, is observed after chemoradiotherapy. This radiation-induced liver injury (RILI) can potentially lead to overstaging. A systematic search for potential cases of RILI after (chemo)radiotherapy for esophageal cancer was performed in the electronic reports from all PET-CT scans made between 2006 and 2015 in our hospital. Additional data about potential cases were obtained from the electronic medical records. A literature review of RILI was also performed. Of 205 patients undergoing nCRT, 6 cases with localized increased FDG uptake in the caudate or left liver lobe following nCRT for esophageal cancer were identified. None of these patients had signs of liver metastases with additional imaging, during surgery, on biopsy, or during follow-up (range 11-46 months). At our institute, the incidence of RILI after neoadjuvant chemoradiotherapy for esophageal cancer was 3%. In the literature, RILI is described in about 8% of patients at the time of restaging. FDG-avid lesions occur in the high radiation dose area, usually corresponding to the caudate or left liver lobe. FDG accumulation in the caudate or left liver lobe after CRT in the area that received a high radiation dose may be caused by metastases or RILI. Awareness of the pitfall of high FDG uptake in RILI is crucial to avoid misinterpretation and overstaging. (orig.)

Borderline personality disorder in men: A literature review and illustrative case vignettes.

Science.gov (United States)

Bayes, Adam; Parker, Gordon

2017-11-01

The aim is to review the salient literature on borderline personality disorder (BPD) in men and link those findings with case vignettes. We provide a literature review and then report case examples of those who met DSM and clinical BPD criteria, and consider the extent to which the small male sub-set corresponded developmentally and phenomenologically with prototypic BPD in women. The review considered phenomenological, epidemiological, biological and developmental BPD factors, finding BPD men evidence elevated substance abuse, and 'externalising' patterns of behavior, antisocial personality traits, violent self-harm and interpersonal aggression, whereas women display more 'internalising' strategies. The five male vignettes enriched the literature review providing support for gender differences reported in our review. The literature and case vignette findings should assist clinicians in recognising that BPD in men may not be as rare as generally viewed, and which may reflect BPD being commonly viewed as weighted to women and being misdiagnosed as an antisocial personality disorder (ASPD) in men.

Loewen, Liz; Roudsari, Abdul

2017-01-01

This paper outlines a systematic literature review undertaken to establish current evidence regarding the impact of Business Intelligence (BI) on health system decision making and organizational performance. The review also examined BI implementation factors contributing to these constructs. Following the systematic review, inductive content analysis was used to categorize themes within the eight articles identified. This study demonstrated there is little evidence based literature focused on BI impact on organizational decision making and performance within health care. There was evidence found that BI does improve decision making. Implementation success was found to be dependent on several factors, many of which relate to broader organizational culture and readiness.

Problematizing the concept ‘epistemological access’: A review of literature

Directory of Open Access Journals (Sweden)

Lucinda du Plooy

2014-07-01

Full Text Available This paper provides a review of literature which aims at problematizing the concept ‘epistemological access”, a fairly under-researched topic in South African education. Morrow’s distinction between formal access (institutional access and epistemological access (access to the goods distributed by the institution is used as a conceptual framework. We argue that the meaning of the concept ‘epistemological access’ as Morrow intended was borne out of a particular political need that arose in higher education; the need to democratize access to higher education. The dearth of literature on the concept “epistemological access” and its meaning for access to basic education, especially foundation phase schooling, therefore warranted this literature review.

Methods: The process of revising included finding and selecting literature from multidisciplinary sources, and encompassed both published papers and ‘grey’ literature, i.e. material which had not been reviewed for publication. Results: The study found that thinking has moved on from a focus on the problems of accessing services to exploring ways in which they may function in an integrated way. Conclusions: The study shows how thinking on integrated care for older people has developed, and knowledge of micro, mezzo and macro strategies is now more available.

Emotionally intelligent nurse leadership: a literature review study.

Science.gov (United States)

Akerjordet, Kristin; Severinsson, Elisabeth

2008-07-01

To establish a synthesis of the literature on the theoretical and empirical basis of emotional intelligence and it's linkage to nurse leadership, focusing on subjective well-being and professional development. Emotional intelligence has been acknowledged in the literature as supporting nurse leadership that fosters a healthy work environment, creating inspiring relationships based on mutual trust. Nurse leaders who exhibit characteristics of emotional intelligence enhance organizational, staff and patient outcomes. A literature search was undertaken using international data bases covering the period January 1997 to December 2007. Eighteen articles were included in this integrative review and were thoroughly reviewed by both authors. Emotional intelligence was associated with positive empowerment processes as well as positive organizational outcomes. Emotionally intelligent nurse leadership characterized by self-awareness and supervisory skills highlights positive empowerment processes, creating a favourable work climate characterized by resilience, innovation and change. Emotional intelligence cannot be considered a general panacea, but it may offer new ways of thinking and being for nurse leaders, as it takes the intelligence of feelings more seriously by continually reflecting, evaluating and improving leadership and supervisory skills.

Kouta, Christiana; Kaite, Charis P

2011-01-01

This article aims to examine gender stereotypes in relation to men in nursing, discuss gender discrimination cases in nursing, and explore methods used for promoting equal educational opportunities during nursing studies. The literature review was based on related databases, such as CINAHL, Science Direct, MEDLINE, and EBSCO. Legal case studies are included in order to provide a more practical example of those barriers existing for men pursuing nursing, as well as statistical data concerning gender discrimination and male attrition to nursing schools in relation to those barriers. These strengthen the validity of the manuscript. Literature review showed that gender discrimination is still prevalent within nursing profession. Nursing faculty should prepare male nursing students to interact effectively with female clients as well. Role modeling the therapeutic relationship with clients is one strategy that may help male students. In general, the faculty should provide equal learning opportunities to nursing students.

Engagement at work: a review of the literature.

Science.gov (United States)

Simpson, Michelle R

2009-07-01

Engagement at work has emerged as a potentially important employee performance and organizational management topic, however, the definition and measurement of engagement at work, and more specifically, nurse engagement, is poorly understood. The objective of this paper is to examine the current state of knowledge about engagement at work through a review of the literature. This review highlights the four lines of engagement research and focuses on the determinants and consequences of engagement at work. Methodological issues, as identified in the current research, and recommendations for future nurse-based engagement research are provided. A systematic review of the business, organizational psychology, and health sciences and health administration literature about engagement at work (1990-2007) was performed. The electronic databases for Health Sciences and Health Administration (CINAHL, MEDLINE), Business (ABI INFORM), and Psychology (PsycINFO) were systematically searched. Due to the limited amount of research that has examined engagement among the nursing workforce, published research that included varying employee types were included in this review. The selection criteria for this review include those studies that were: (1) written in English and (2) examined engagement at work in employee populations of any type within any work setting. The literature review identified four distinct lines of research that has focused on engagement within the employee work role. Of the 32 engagement-based articles referenced in this paper, a sample of 20 studies report on the examination of antecedents and/or consequences of engagement at work among varying employee types and work settings. Key findings suggest organizational factors versus individual contributors significantly impact engagement at work. A common implication in this body of research was that of the performance-based impact. The study of nurses' work engagement and its relationship to nurses' organizational

Conegundes De Jesus, Camila Kiyomi; Salerno, Mario Sergio

2018-05-09

Patents and patent portfolios are gaining attention in the last decades, from the called 'pro-patent era' to the recent billionaire transactions involving patent portfolios. The field is growing in importance, both theoretically and practically and despite having substantial literature on new product development portfolio management, we have not found an article relating this theory to patent portfolios. Areas covered: The paper develops a systematic literature review on patent portfolio management to organize the evolution and tendencies of patent portfolio management, highlighting distinctive features of patent portfolio management. Interview with IP manager of three life sciences companies, including a leading multinational group provided relevant information about patent portfolio management. Expert opinion: Based on the systematic literature review on portfolio management, more specifically, on new product development portfolio theory, and interview the paper proposes the paper proposes a reference model to manage patent portfolios. The model comprises four stages aligned with the three goals of the NPD portfolio management: 1 - Linking strategy of the Company's NPD Portfolio to Patent Portfolio; 2 - Balancing the portfolio in buckets; 3 - Patent Valuation (maximizing valuation); 4 - Regularly reviewing the patent portfolio.

Escoffery, Cam; Rodgers, Kirsten C; Kegler, Michelle C; Ayala, Mary; Pinsker, Erika; Haardörfer, Regine

2014-06-19

Cancer remains the second leading cause of mortality in the United States. Special events such as health fairs, screening days or cultural festivals are employed often for community education about cancer screening. A previous systematic review of the published literature was conducted in 2012-2013. The purpose of this study was to conduct a grey literature component of special events that promote breast, cervical and colorectal cancer screening in the U.S. We conducted a grey literature search of dissertations/theses and conference abstracts. The theses/dissertations were restricted to those: 1) written in English, 2) published from January 1990 to December 2011, 3) examined at least one of the predefined categories of special events, 4) involved cancer screening for breast, cervical, and/or colorectal cancer, 5) included outcome data, and 6) conducted in the United States. A review of U.S. public health and cancer conference abstracts, that were readily available and had focused on at least of 3 cancer types and included outcome data, was conducted. Data were abstracted on the purpose, location, primary audience(s), activities conducted, screening provided onsite or referrals, and evaluation results. The grey literature review found 6 special events. The types of events found added to the numbers found in the systematic review, especially receptions or parties and cultural festivals/events. All focused on increasing breast and cervical cancer screening except one that focused on breast cancer only. The reach of these events was targeted at mostly minorities or underserved communities. Common evidence-based strategies were group education, small media, and reducing structural barriers. Group education involved presentations from physicians, lay-health advisors, or cancer survivors, while reducing structural barriers included activities such as providing screening appointment sign-ups at the event or providing transportation for event participants.

Makopa Kenda, Israel; Agoub, Mohamed; Ahami, A O T

2014-01-01

Any human activity generates noise. It is considered as a risk factor for people's health. The present review of literature has assessed the impact of noise on mental health; it is summarized into four points: objective, methods, results and conclusion. The main objective of this study is to expose the actual knowledge state of noise effects on mental health after overview and critical analysis of literature to identify the acquired and shortcomings, to reflect on research direction in terms of noise pollution in the future. The literature review was conducted based on: research of keys words in articles published, research of the number of quotations of articles in Journal Citation Reports (JCR), published in web of science, research of impact factor of journals. One hundred articles were selected, after analyzing contents, items were classified into: fundamental studies (25%), experimental studies (50%), and epidemiological studies (25%). The fundamental studies have verified the hypothesis according to which noise generates stress. Researchers have dosed hormones of stress in plasma, urine and saliva in individuals exposed to noise of different decibels. The results found were unanimous: The rates of stress hormones found, were significantly high in three liquids. This means that noise causes stress. For experimental studies, researchers have experienced the role of noise on memory, attention and performance. Human subjects were exposed to different decibels to assess level of disruption to their memory, attention, and performance. The results revealed that noise disturbs memory, distracts attention and decreases performance. Experimental studies are the most abundant and constitute 50% of the current literature review.The epidemiological studies have evaluated the intellectual performance of students in schools located in noisy environments and residents in areas surrounding airports, railways and highways. RESULTS have revealed that students in schools located

Social marketing and breastfeeding: a literature review.

Science.gov (United States)

Schmidt, Manuela

2013-02-08

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

Effects of patient death on nursing staff: a literature review.

Science.gov (United States)

Wilson, Janet; Kirshbaum, Marilyn

There were 509090 deaths recorded in England and Wales for 2008 (Office for National Statistics, 2010); of these, over 56% (260000) occurred in NHS hospitals. The death of a patient is an event that most, if not all, nursing staff will encounter during their work. This experience can elicit physical, cognitive, behavioural, spiritual and emotional responses (Parkes, 1998). The aim of this literature review is to explore how the death of patients in a hospital setting impact on nursing staff. A review of the literature was undertaken using the online databases CINAHL, Medline and PsychInfo. The search was limited to articles in the English language and those from peer-reviewed journals. Themes arising from the literature review included: the theoretical context; the emotional impact; the culture of the healthcare setting; staff's previous life experiences; and support available for healthcare staff. The death of patients does have an impact on nurses. This can affect them both in their work environment and outside of work. Education around grief theory and support from others are helpful for staff in developing strategies for coping with patient deaths.

Tubercular prosthetic joint infection (TB-PJI) is an uncommon complication. Lack of evidence of systemic tuberculosis and clinical suspicion could bring a delay in the time of the diagnosis. The aims of this study are to underline the importance of awareness and suspicion of mycobacterial infection in the differential diagnosis in PJI and to evaluate the appropriateness of different therapeutic options. Case report and literature review. We report two cases of TB-PJI after total knee arthroplasty in Caucasian patients without prior history of tubercular disease or exposure. In both cases, the diagnosis was obtained years after the onset of symptoms. Despite that, both patients improved during antitubercular treatment (a four-drug regimen consisting of rifampicin, isoniazid, ethambutol, and pyrazinamide for 2 months, followed by rifampicin and isoniazid). Moreover, after an 18-month course of treatment, there was no need for surgical therapy. The result of the literature review allows us to identify 64 cases of TB-PJI. Many differences in both medical and surgical management have been found, among those reviewed cases. Considering our experience and the literature review, we recommend considering a conservative approach (debridement and adequate antituberculous chemotherapy) as a suitable and safe option.

Regeneration and health: a structured, rapid literature review.

McCartney, G; Hearty, W; Taulbut, M; Mitchell, R; Dryden, R; Collins, C

2017-07-01

To identify and synthesise what is known about the impacts of regeneration on health, health inequalities and their socio-economic determinants. Rapid, structured literature review. A rapid, structured approach was undertaken to identifying relevant studies involving a search of peer-reviewed literature databases, an Internet search to identify relevant grey literature, and a review of articles citing two key systematic reviews. The identified citations were screened, critically appraised according to the research design and narratively synthesised. Of the 1382 identified citations, 46 were screened as relevant to the review and included in the synthesis. Fifteen citations were reviews but most of the evidence identified or included within the reviews was of medium or low quality due to a lack of longitudinal follow-up, low response rates or attrition. The evidence base on the impacts of regeneration is generally not of high quality and is prone to bias. However, it is theorised as being an important means of addressing the socio-economic determinants of health. Housing refurbishment (generally, and for specific improvements) seems likely to lead to small improvements in health, whereas rehousing and mixed-tenure approaches have less clear impacts on health and carry risks of disruption to social networks and higher rents. Changes in the social composition of communities (gentrification) is a common outcome of regeneration and some 'partnership' approaches to regeneration have been shown to have caused difficulties within communities. The evidence base for regeneration activities is limited but they have substantial potential to contribute to improving population health. Better quality evidence is available for there being positive health impacts from housing-led regeneration programmes involving refurbishment and specific housing improvements. There is also some evidence of the potential harms of regeneration activities, including social stratification

A literature review of safety culture.

Energy Technology Data Exchange (ETDEWEB)

Cole, Kerstan Suzanne; Stevens-Adams, Susan Marie; Wenner, Caren A.

2013-03-01

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

Several types of vasculitis have been observed and reported in temporal association with the administration of various vaccines. A systematic review of current evidence is lacking. This systematic literature review aimed to assess available evidence and current reporting practice of vasculitides as adverse events following immunization (AEFI). We reviewed the literature from 1st January 1994 to 30th June 2014. This review comprises randomized controlled trials, observational studies, case series, case reports, reviews and comments regardless of vaccine and target population. The initial search resulted in the identification of 6656 articles. Of these, 157 articles were assessed for eligibility and 75 studies were considered for analysis, including 6 retrospective/observational studies, 2 randomized controlled trials, 7 reviews, 11 case series, 46 case reports and 3 comments. Most of the larger, higher quality studies found no causal association between vaccination and subsequent development of vasculitis, including several studies on Kawasaki disease and Henoch-Schönlein purpura (IgA vasculitis). Smaller case series reported a few cases of vasculitis following BCG and vaccines against influenza and hepatitis. Only 24% of the articles reported using a case definition of vasculitis. Existing literature does not allow establishing a causative link between vaccination and vasculitides. Further investigations were strengthened by the use of standardized case definitions and methods for data collection, analysis and presentation to improve data comparability and interpretation of vasculitis cases following immunization.

Metastasis of cervical cancer to breast: A case report and review of literature

Directory of Open Access Journals (Sweden)

Ankit Mangla

2017-08-01

Full Text Available Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis. Our patient, a 51-year old woman presented with breast lump and history of post-menopausal bleeding. Upon further workup, the patient was diagnosed with cervical cancer. The mammogram and ultrasound of the breast showed multiple lumps within the breast. Histopathology of the breast mass showed metastatic deposit in the breast from cervical cancer. The patient was treated with radiation therapy to the cervix along with concurrent chemotherapy for local control of pain. After completion of local treatment, she started systemic chemotherapy, however she developed health-care associated pneumonia and subdural hematoma leading to deterioration in her performance status. The patient opted for hospice care and died 2 months later. In this report, we will review the presentation of the 38 cases reported in literature and the imaging and histopathologic findings of metastatic deposits to the breast.

Objective: To analyze the clinical, imaging and pathological features of adamantinoma of long bone to aid preoperative diagnosis. Methods: A case of adamantinoma of long bone was reported and the related literature was reviewed. Results: Literature review showed that long bone ameloblastoma was more common in young adults older than 20 years of age (86.3%) and occurred mainly in the tibial shaft (90%). The clinical, imaging and pathological features in our patient were consistent with those reported in the literature. Among 39 cases in the Chinese literature, radiographic findings included uni-or multi-cystic bone destruction with well-defined borders (87.2%), bone expansion (61.8%), partial loss of cortical bone (26.5%), bone sclerosis (38.2%), and no periosteal new bone reaction (100%). Pathology showed epithelial and fibrous differentiation. Conclusion: Adamantinoma of long bone should be considered in patients older than 20 years of age with tibial lesions that have imaging characteristics of benign bone tumors or some malignant features.

Goyal, Sanjeev; Grover, Sandeep

2012-09-01

Advanced manufacturing technology (AMT) provides advantages to manufacturing managers in terms of flexibility, quality, reduced delivery times, and global competitiveness. Although a large number of publications had presented the importance of this technology, only a few had delved into related literature review. Considering the importance of this technology and the recent contributions by various authors, the present paper conducts a more comprehensive review. Literature was reviewed in a way that will help researchers, academicians, and practitioners to take a closer look at the implementation, evaluation, and justification of the AMT. The authors reviewed various papers, proposed a different classification scheme, and identified certain gaps that will provide hints for further research in AMT management.

Our purpose was to evaluate the survival of patients with pleural and intraperitoneal malignant mesothelioma and, particularly, to estimate the efficacy of chemotherapy as well as radiotherapy and surgery. A review of the literature with respect to these parameters is included. Thirty-five patients with malignant mesothelioma (28 with pleural and 7 with intraperitoneal) were enrolled. Twenty-eight patients underwent chemotherapy, 7/35 radiation and 9/35 surgery (2 with pleural and 7 with abdominal disease). Combination chemotherapy included cisplatin-gemcitabine, cisplatin (or carboplatin) with premetrexed and doxorubicin-cyclophosphamide. In 2/28 patients with pleural mesothelioma the tumor was excised and in 7 with intraperitoneal disease, surgical therapy was palliative and there was survival prolongation. Radiotherapy was only palliative. Chemotherapy produced a very low response: 2/28 (7.14%) patients achieved a partial response. The median survival was 17 months, 4-year survival, 24.4% and 5-year survival, 12.12%. No serious toxicity was observed. Malignant mesothelioma of the pleura and intraperitoneum is a slow-growing disease which is indicated by the long survival, despite the failure of chemotherapy, radiation therapy and surgery.

Exposure to non-ionizing electromagnetic radiation and public health : review of safety levels

International Nuclear Information System (INIS)

Ubeda, A.; Trillo, M. A.

2005-01-01

The potential health effects of the exposure to non-ionizing electromagnetic radiation are a source of increasing interest on the part of the public and the authorities. This article summarizes the theoretical-experimental basis supporting the safety levels proposed by international committees, and reviews the recent scientific literature on non-ionizing radiation's bioeffects that are relevant to the validation or modification of the present exposure limits. Because of its social interest, special consideration is given to power frequency fields (50-60Hz) and to the radio communication signals of mobile telephony. The paper also describes how interpretations of the scientific evidence, other than those of the international committees, have generated some controversy and have provided a basis for more restrictive limits, like those adopted in Europe by Switzerland and Italy. The article also identifies some gaps in the present scientific knowledge on the bioelectromagnetics discipline and proposes that additional research is needed to complete our present knowledge on the biological responses to non-ionizing radiation.

Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

Secondary intracranial meningiomas after high-dose cranial irradiation: report of five cases and review of the literature

International Nuclear Information System (INIS)

Strojan, Primoz; Popovic, Mara; Jereb, Berta

2000-01-01

Purpose: To review cases of secondary intracranial meningiomas following high-dose cranial irradiation (≥ 10 Gy) identified in Slovenia between 1968 and 1998, to determine their histological profile and to review the literature on this topic. Methods and Materials: Personal files of patients treated for secondary intracranial meningioma during a 31-year period were reviewed. In cases which met the criteria for radiation-induced tumors, steroid hormone receptor and Ki-67 status were analyzed. For the literature review, computerized database systems and reference lists from respective publications were used. Results: Five patients (2 females, 3 males), 3-11 years old at the time of cranial irradiation, developed secondary meningioma after a latency period of 9.5-31.5 years. Three patients had multiple tumors and 2 developed recurrent disease. Of 9 histologically examined tumors, 5 were graded as benign and 4 as atypical meningiomas, with Ki-67 proliferative index 3.2 ± 3.6 and 10 ± 6, respectively. The ratio between positive and negative meningiomas regarding immunostaining for progesterone and estrogen receptors was eight-to-one and six-to-three, respectively. Cumulative actuarial risk of secondary meningioma in a cohort of 445 children 16 years or younger treated with high-dose cranial irradiation between 1968 and 1990 in Slovenia at 10, 20, and 25 years was 0.53%, 1.2%, and 8.18%, respectively. Out of 126 cases of radiation-induced meningiomas reported, 57% were females and 43% were males, with mean age at presentation 33 ± 17.3 years. The majority (68%) of patients was irradiated during childhood. The latency period was significantly shorter in those who aged 5 years or less at the time of cranial irradiation (p = 0.04), and in those with atypical/anaplastic tumor (p = 0.01). Correlation between radiation dose and latency period could not be found. Conclusion: Secondary meningiomas following high-dose cranial irradiation are characterized by younger age at

Melatonin as Protection Against Radiation Injury

DEFF Research Database (Denmark)

Zetner, D.; Andersen, L. P H; Rosenberg, J.

2016-01-01

Introduction: Radiation is widely used in the treatment of various cancers and in radiological imaging procedures. Ionizing radiation causes adverse effects, leading to decreased quality of life in patients, by releasing free radicals that cause oxidative stress and tissue damage. The sleep......-hormone melatonin is a free radical scavenger, and induces several anti-oxidative enzymes. This review investigates the scientific literature on the protective effects of melatonin against exposure to ionizing radiation, and discusses the clinical potential of melatonin as prophylactic treatment against ionizing...... and protected against radiation enteritis. These protective effects were only documented when melatonin was administered prior to exposure to ionizing radiation. Discussion: This review documents that melatonin effectively protects animals against injury to healthy tissues from ionizing radiation. However...

Computed tomography shielding methods: a literature review.

Science.gov (United States)

Curtis, Jessica Ryann

2010-01-01

To investigate available shielding methods in an effort to further awareness and understanding of existing preventive measures related to patient exposure in computed tomography (CT) scanning. Searches were conducted to locate literature discussing the effectiveness of commercially available shields. Literature containing information regarding breast, gonad, eye and thyroid shielding was identified. Because of rapidly advancing technology, the selection of articles was limited to those published within the past 5 years. The selected studies were examined using the following topics as guidelines: the effectiveness of the shield (percentage of dose reduction), the shield's effect on image quality, arguments for or against its use (including practicality) and overall recommendation for its use in clinical practice. Only a limited number of studies have been performed on the use of shields for the eyes, thyroid and gonads, but the evidence shows an overall benefit to their use. Breast shielding has been the most studied shielding method, with consistent agreement throughout the literature on its effectiveness at reducing radiation dose. The effect of shielding on image quality was not remarkable in a majority of studies. Although it is noted that more studies need to be conducted regarding the impact on image quality, the currently published literature stresses the importance of shielding in reducing dose. Commercially available shields for the breast, thyroid, eyes and gonads should be implemented in clinical practice. Further research is needed to ascertain the prevalence of shielding in the clinical setting.

Self-weighing in weight management: a systematic literature review.

Zheng, Yaguang; Klem, Mary Lou; Sereika, Susan M; Danford, Cynthia A; Ewing, Linda J; Burke, Lora E

2015-02-01

Regular self-weighing, which in this article is defined as weighing oneself regularly over a period of time (e.g., daily, weekly), is recommended as a weight loss strategy. However, the published literature lacks a review of the recent evidence provided by prospective, longitudinal studies. Moreover, no paper has reviewed the psychological effects of self-weighing. Therefore, the objective is to review the literature related to longitudinal associations between self-weighing and weight change as well as the psychological outcomes. Electronic literature searches in PubMed, Ovid PsycINFO, and Ebscohost CINAHL were conducted. Keywords included overweight, obesity, self-weighing, etc. Inclusion criteria included trials that were published in the past 25 years in English; participants were adults seeking weight loss treatment; results were based on longitudinal data. The results (N=17 studies) revealed that regular self-weighing was associated with more weight loss and not with adverse psychological outcomes (e.g., depression, anxiety). Findings demonstrated that the effect sizes of association between self-weighing and weight change varied across studies and also that the reported frequency of self-weighing varied across studies. The findings from prospective, longitudinal studies provide evidence that regular self-weighing has been associated with weight loss and not with negative psychological outcomes. © 2014 The Obesity Society.

Burget, Mirjam; Bardone, Emanuele; Pedaste, Margus

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.

Toode, Kristi; Routasalo, Pirkko; Suominen, Tarja

2011-02-01

The aim of this review is to describe nurses' work motivation from the perspective of staff nurses. This information would be useful for the development of motivation strategies and further research into nurses' work motivation. A thorough review of the research literature. The literature search was performed using four databases: CINAHL, PubMed, PsychINFO, and SocINDEX. Only studies that met the following criteria were selected for review: (1) were published between 1990 and 2009, (2) were written in English, (3) dealt with work motivation, (4) concerned working staff nurses, (5) involved empirical research, (6) clearly and explicitly provided the research results about the factors affecting nurses' work motivation. Altogether 24 studies met these criteria and were included in this review. Inductive content analysis was carried out to analyse and categorise the data. Nursing research has neither clear understanding nor consensus about the concept of work motivation; nor has a universal definition been adopted. Despite limited empirical evidence it may be concluded that staff nurses appear to be motivated. Five categories of factors affecting their work motivation were identified: (1) work-place characteristics, (2) working conditions, (3) personal characteristics, (4) individual priorities, and (5) internal psychological states. Further research is needed to gain a more comprehensive insight into nurses' work motivation and the factors affecting it. This can be achieved by defining the concept of work motivation as precisely as possible, working out a pertinent research methodology, and subsequently developing and testing a theoretical model of nurses' work motivation.

A non-systematic review on Medline, PubMed and Cochrane library databases from 1966 to 2010 using the following keywords: "multiple sclerosis", "self-care", "self-management" and specific symptoms keywords. Clinical trials and randomized clinical trials, as well as literature reviews published in English, French and German will be analyzed. Counseling is a part of the non-pharmacological management of chronic illnesses such as multiple sclerosis. Symptoms' diversity and the different clinical forms limit standardized programs of self-care management, applicable to patients. In the literature review, counseling programs have often low metrology. A behavior change with patients and medical staff could exist. To empower the patient, to reduce symptoms' impact and to improve treatment access are the aims of educational therapy. Therapeutic education program for multiple sclerosis patients could progress with their standardization and assessment, for each sign. To promote the educational therapy of multiple sclerosis patients, a specific training for medical staff, as specific financing are necessary. 2011 Elsevier Masson SAS. All rights reserved.

Full Text Available This literature review focuses on researches undertaken since 1980s onwards. The purpose of the study is to identify existing gaps on workplace safety and health management and propose future research areas. The review adds value to existing electronic database through integration of researches' results. To identify existing gaps, a systematic literature review approach has been used. The reviews were undertaken through keywords and safety related topics. In the literature, various characteristics of workplace safety and health problems were found emanating from the lack of operational activities of the employees, internal working environment and external environment those impose hazards on employee temporarily, permanently and on working environments. The integration of multidisciplinary approaches and collaborative model of hub and peripheral industries to protect workplace safety hazards to develop multilevel model has been undermined in many researches. The other face of finding is that knowledge transfer mechanism and industrial topology factors are left. Some researches finding showed that they have focused on single problems related to health and health factors leaving universal improving workplace safety. In general, this literature reviews compare various studies output based on their research method and findings to fills gap and add value to a body of knowledge.

Gossypibomas in India - A systematic literature review

Directory of Open Access Journals (Sweden)

T Patial

2017-01-01

Full Text Available Purpose of Review: Gossypibomas remain a dreaded and unwanted complication of surgical practice. Despite significant interest and numerous guidelines, the number of reported cases remains sparse due to various factors, including potential legal implications. Herein, we review related data from India to ascertain if the problem is better or worse than that reported in world literature. Materials and Methods: A literature search was performed on PubMed and Google Scholar, to collect and analyze all case reports and case reviews regarding the condition in India. Results: On analysis of the results, there were 100 publications reporting a total of 126 events. The average patient age was 38.65 years. Average time to discovery was 1225.62 days. Forty-nine percent of reported cases were discovered within the 1 st year. The most common clinical features were pain (73.8%, palpable mass (47.6%, vomiting (35%, abdominal distention (26%, and fever (12.6%. Spontaneous expulsion of the gossypiboma was noted in five cases (3.96%. Transmural migration was seen in 36 cases (28.57%. Conclusions: Despite advancements in surgical approaches and preventive measures, gossypibomas continue to be a cause of significant morbidity. A safe working culture, open communication, teamwork, and an accurate sponge count remain our best defence against this often unpredictable complication of surgery.

Laparoscopic Whipple procedure: review of the literature.

Science.gov (United States)

Gagner, Michel; Palermo, Mariano

2009-01-01

Laparoscopic pancreatic surgery represents one of the most advanced applications for laparoscopic surgery currently in use. In the past, minimally invasive techniques were only used for diagnostic laparoscopy, staging of pancreatic cancer, and palliative procedures for unresectable pancreatic cancer. With new advances in technology and instrumentation, some sophisticated procedures are currently available, such as the Whipple procedure, one of the most sophisticated applications of minimally invasive surgery. A review of the literature shows that 146 laparoscopic Whipple procedures have been published worldwide since 1994. The authors analyzed blood loss, mean operating time, hospital stay, conversion rate, mean age, mortality rate, lymph nodes in the pathologic findings, follow up, and complications. Mean age was 59.1 years; mean operating time was 439 min. The average blood loss for the reviewed literature was 143 mL; median hospital stay was 18 days; conversion rate was 46%; number of lymph nodes in the pathologic findings was 19; and mortalities related to the procedure was low, 2 patients (1.3%) and the complication rate was 16% (23/46 patients). Complications included 2 hemorrhages, 4 bowel obstructions, 1 stress ulcer, 1 delay of gastric emptying, 4 pneumonias, and 11 leaks. This review demonstrates that the laparoscopic Whipple procedure is not only feasible but also safe, with low mortality and acceptable rates of complications.

2008-09-01

Full Text Available Recent fraud scandals involving highly known corporations like Enron, WorldCom, and Xerox have eroded public confidence in financial reporting. At the same time, the auditing profession has suffered a big hit. In this scenario, Continuous Auditing (CA seems to have emerged as a response to recover the credibility of the auditing profession as well as meeting Sarbanes-Oxley (SOX requirements. This study, that adopts an exploratory approach, analyzes the existing literature on this topic. First, we address the concepts, models and implications of CA. After, throughout a search on the journals indexed at the CAPES's Basis, a literature review is conducted. A total of 57 articles were selected.

Incorporation of constructivist assumptions into problem-based instruction: a literature review.

Science.gov (United States)

Kantar, Lina

2014-05-01

The purpose of this literature review was to explore the use of distinct assumptions of constructivism when studying the impact of problem-based learning (PBL) on learners in undergraduate nursing programs. Content analysis research technique. The literature review included information retrieved from sources selected via electronic databases, such as EBSCOhost, ProQuest, Sage Publications, SLACK Incorporation, Springhouse Corporation, and Digital Dissertations. The literature review was conducted utilizing key terms and phrases associated with problem-based learning in undergraduate nursing education. Out of the 100 reviewed abstracts, only 15 studies met the inclusion criteria for the review. Four constructivist assumptions based the review process allowing for analysis and evaluation of the findings, followed by identification of issues and recommendations for the discipline and its research practice in the field of PBL. This literature review provided evidence that the nursing discipline is employing PBL in its programs, yet with limited data supporting conceptions of the constructivist perspective underlying this pedagogical approach. Three major issues were assessed and formed the basis for subsequent recommendations: (a) limited use of a theoretical framework and absence of constructivism in most of the studies, (b) incompatibility between research measures and research outcomes, and (c) brief exposure to PBL during which the change was measured. Educators have made the right choice in employing PBL as a pedagogical practice, yet the need to base implementation on constructivism is mandatory if the aim is a better preparation of graduates for practice. Undeniably there is limited convincing evidence regarding integration of constructivism in nursing education. Research that assesses the impact of PBL on learners' problem-solving and communication skills, self-direction, and motivation is paramount. Copyright © 2014 Elsevier Ltd. All rights reserved.

2011-05-01

The aim of the study was to report the results of a systematically conducted literature review of empirical studies about healthcare organizations' ethics and management or leadership issues. Electronic databases MEDLINE and CINAHL yielded 909 citations. After a two stage application of the inclusion and exclusion criteria 56 full-text articles were included in the review. No large research programs were identified. Most of the studies were in acute hospital settings from the 1990s onwards. The studies focused on ethical challenges, dilemmas in practice, employee moral distress and ethical climates or environments. Study samples typically consisted of healthcare practitioners, operational, executive and strategic managers. Data collection was mainly by questionnaires or interviews and most of the studies were descriptive, correlational and cross-sectional. There is need to develop conceptual clarity and a theoretical framework around the subject of organizational ethics and the breadth of the contexts and scope of the research needs to be increased. © The Author(s) 2011

2014-10-01

Infections caused by Nocardia farcinica are potentially lethal because of the organism's tendency to disseminate and resist antibiotics. Central nervous system involvement has been documented in 30% of infections caused N. farcinica. Case report and review of the literature. A case of primary brain abscess caused by N. farcinica, identified by 16SrRNA sequencing, is presented, and 39 cases reported previously in the literature are reviewed. Our patient underwent a neuronavigation-guided right frontal craniotomy and was treated with trimethoprim/sulfamethoxazole and amoxicillin-clavulanic acid for 12 mo. He showed marginal improvement in his prior left hemiparesis at the last review 14 months later. Cases of N. farcinica infections are being reported increasingly because of recent changes in taxonomy and diagnostic methodology. This change in epidemiology has implications for therapy because of the organism's pathogenicity and natural resistance to multiple antimicrobial agents, including third-generation cephalosporins. Any delay in starting appropriate antibiotic therapy can have adverse consequences.

Toothbrush Contamination: A Review of the Literature

Directory of Open Access Journals (Sweden)

Michelle R. Frazelle

2012-01-01

Full Text Available Toothbrushes are commonly used in hospital settings and may harbor potentially harmful microorganisms. A peer-reviewed literature review was conducted to evaluate the cumulative state of knowledge related to toothbrush contamination and its possible role in disease transmission. A systematic review was conducted on adult human subjects through three distinct searches. The review resulted in seven experimental and three descriptive studies which identified multiple concepts related to toothbrush contamination to include contamination, methods for decontamination, storage, design, and environmental factors. The selected studies found that toothbrushes of healthy and oral diseased adults become contaminated with pathogenic bacteria from the dental plaque, design, environment, or a combination of factors. There are no studies that specifically examine toothbrush contamination and the role of environmental factors, toothbrush contamination, and vulnerable populations in the hospital setting (e.g., critically ill adults and toothbrush use in nursing clinical practice.

Protection of humans from ultraviolet radiation through the use of textiles: a review

International Nuclear Information System (INIS)

Capjack, L.; Kerr, N.; Davis, S.; Fedosejevs, R.; Hatch, K.L.; Markee, N.L.

1994-01-01

One of the growing concerns of the present decade is the health risk associated with exposure to ultraviolet radiation (UVR) and its link with problems such as carcinogenesis, cataracts, sunburn, and photoaging. For protection from UVR, medical experts recommend avoiding exposure, using sunscreens, donning hats, and covering up with clothing. Research on the solar-protective value of clothing, however, still leaves many questions unanswered. This review of literature identifies the need for appropriate protection from the sun, especially for children, and the benefits of clothing as protection. The methods and difficulties associated with assessing the UVR protection and the definition of the sun protection factor (SPF) of clothing are outlined and discussed. Studies using in vivo, radiometric, and spectrophotometric methodologies to assess the UVR transmission throughfabrics are examined. Fabric variables, identified in the literature, that have been found to affect UVR transmission values are discussed

Radiotherapy and chemotherapy can effectively control cancer but can also cause new second cancers to develop as long-term complications especially in childhood cancer. We experienced two patients with second malignant solid neoplasm who had been treated with radiation and chemotherapy for childhood cancers. One female patients with rhabdomyosarcoma of the right popliteal fossa was treated with radiotherapy at total dose of 54 Gy. Three years and seven months later, osteosarcoma developed in the field of radiation therapy. The other male patient with non-Hodgkin's lymphoma of the small bowel was treated with radiotherapy and leiomyosarcoma developed in the field of radiotherapy 18 years later. We reviewed the literature of the second malignant neoplasm in children in respect of risk factors. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments. Particularly patients treated for childhood cancers

Directory of Open Access Journals (Sweden)

Huseyin Uzunboylu

2015-07-01

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

Dextromethorphan, chlorphenamine and serotonin toxicity: case report and systematic literature review

Science.gov (United States)

Monte, Andrew A; Chuang, Ryan; Bodmer, Michael

2010-01-01

The aim of this review was to describe a patient with serotonin toxicity after an overdose of dextromethorphan and chlorphenamine and to perform a systematic literature review exploring whether dextromethorphan and chlorphenamine may be equally contributory in the development of serotonin toxicity in overdose. A Medline literature review was undertaken to identify cases of serotonin toxicity due to dextromethorphan and/or chlorphenamine. Case reports were included if they included information on the ingested dose or plasma concentrations of dextromethorphan and/or chlorphenamine, information about co-ingestions and detailed clinical information to evaluate for serotonin toxicity. Cases were reviewed by two toxicologists and serotonin toxicity, defined by the Hunter criteria, was diagnosed when appropriate. The literature was then reviewed to evaluate whether chlorphenamine may be a serotonergic agent. One hundred and fifty-five articles of dextromethorphan or chlorphenamine poisoning were identified. There were 23 case reports of dextromethorphan, of which 18 were excluded for lack of serotonin toxicity. No cases were identified in which serotonin toxicity could be solely attributed to chlorphenamine. This left six cases of dextrometorphane and/or chlorphenamine overdose, including our own, in which serotonin toxicity could be diagnosed based on the presented clinical information. In three of the six eligible cases dextromethorphan and chlorphenamine were the only overdosed drugs. There is substantial evidence from the literature that chlorphenamine is a similarly potent serotonin re-uptake inhibitor when compared with dextrometorphan. Chlorphenamine is a serotonergic medication and combinations of chlorphenamine and dextromethorphan may be dangerous in overdose due to an increased risk of serotonin toxicity. PMID:21175434

Immunomodulatory dietary polysaccharides: a systematic review of the literature

Directory of Open Access Journals (Sweden)

Nelson Erika D

2010-11-01

Full Text Available Abstract Background A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. Methods Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. Results We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. Conclusions Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen. Glucan extracts from the Trametes versicolor

Using computer-based training to facilitate radiation protection review

International Nuclear Information System (INIS)

Abercrombie, J.S.; Copenhaver, E.D.

1989-01-01

In a national laboratory setting, it is necessary to provide radiation protection overview and training to diverse parts of the laboratory population. This includes employees at research reactors, accelerators, waste facilities, radiochemical isotope processing, and analytical laboratories, among others. In addition, our own radiation protection and monitoring staffs must be trained. To assist in the implementation of this full range of training, ORNL has purchased prepackaged computer-based training in health physics and technical mathematics with training modules that can be selected from many topics. By selection of specific modules, appropriate radiation protection review packages can be determined to meet many individual program needs. Because our radiation protection personnel must have some previous radiation protection experience or the equivalent of an associate's degree in radiation protection for entry level, the computer-based training will serve primarily as review of major principles. Others may need very specific prior training to make the computer-based training effective in their work situations. 4 refs

Ownership Structure and Publicness of Firms: A Literature Review

Directory of Open Access Journals (Sweden)

Wisnu Untoro

2017-11-01

Full Text Available There has been an extensive body of literature studying the link between ownership structure and firm performance. Some of them focus on the performance difference across ownership types (i.e. state vs foreign vs private domestic. On the other hand, some studies stress ownership structure on the fraction of ownership based on agency theory (i.e. majority versus minority and its derivatives (e.g. ultimate ownership, cross listing. However, an important element has not been explored while discussing ownership structure of firms which is the concept of publicness of firms. Publicness is important to explain to which extent an organization is related with governmental institutions. In fact, there are many engagements of firms with governmental bodies (e.g. deposit and lending from and to public organization. In this present paper, I provide a comprehensive literature review on the intersection between publicness level of firms and ownership structure. Going deeper, I also provide a literature review on the measurement of publicness and postulate a model to link between these two and firm performance as a venue for future studies.

Midwives and nutrition education during pregnancy: a literature review.

Science.gov (United States)

Arrish, Jamila; Yeatman, Heather; Williamson, Moira

2014-03-01

This review explored the extent to which the role of midwives in nutrition education during pregnancy has been reported in the literature and areas requiring further research were identified. A review of the literature was undertaken. Articles included in the review were published in English, in scholarly journals, and provided information about the knowledge, education, and attitudes of midwives towards nutrition during pregnancy. Few studies were identified. The included studies were exploratory and descriptive. Studies had reported that midwives lacked a basic knowledge of nutrition requirements during pregnancy. This might be attributed to inadequate nutrition education provided in both undergraduate and postgraduate midwifery programmes. The nutrition education components of midwifery courses were not identified within the studies reviewed. Limited international or Australian research is available that reports on the role of midwives in nutrition education during pregnancy and the nutrition content of midwifery curricula. This represents an important omission in midwives capacity to support the health of pregnant women and their babies. More research is required to explore the educational needs of midwives to enhance nutritional care for pregnant women. Copyright © 2013 Australian College of Midwives. Published by Elsevier Ltd.

Steinberg, Susan

2015-01-01

The 2015 Space Radiation Standing Review Panel (from here on referred to as the SRP) met for a site visit in Houston, TX on December 8 - 9, 2015. The SRP met with representatives from the Space Radiation Element and members of the Human Research Program (HRP) to review the updated research plan for the Risk of Radiation Carcinogenesis Cancer Risk. The SRP also reviewed the newly revised Evidence Reports for the Risk of Acute Radiation Syndromes Due to Solar Particle Events (SPEs) (Acute Risk), the Risk of Acute (In-flight) and Late Central Nervous System Effects from Radiation Exposure (CNS Risk), and the Risk of Cardiovascular Disease and Other Degenerative Tissue Effects from Radiation (Degen Risk), as well as a status update on these Risks. The SRP would like to commend Dr. Simonsen, Dr. Huff, Dr. Nelson, and Dr. Patel for their detailed presentations. The Space Radiation Element did a great job presenting a very large volume of material. The SRP considers it to be a strong program that is well-organized, well-coordinated and generates valuable data. The SRP commended the tissue sharing protocols, working groups, systems biology analysis, and standardization of models. In several of the discussed areas the SRP suggested improvements of the research plans in the future. These include the following: It is important that the team has expanded efforts examining immunology and inflammation as important components of the space radiation biological response. This is an overarching and important focus that is likely to apply to all aspects of the program including acute, CVD, CNS, cancer and others. Given that the area of immunology/inflammation is highly complex (and especially so as it relates to radiation), it warrants the expansion of investigators expertise in immunology and inflammation to work with the individual research projects and also the NASA Specialized Center of Research (NSCORs).

Haddaway, Neal Robert; Collins, Alexandra Mary; Coughlin, Deborah; Kirk, Stuart

2015-01-01

Google Scholar (GS), a commonly used web-based academic search engine, catalogues between 2 and 100 million records of both academic and grey literature (articles not formally published by commercial academic publishers). Google Scholar collates results from across the internet and is free to use. As a result it has received considerable attention as a method for searching for literature, particularly in searches for grey literature, as required by systematic reviews. The reliance on GS as a standalone resource has been greatly debated, however, and its efficacy in grey literature searching has not yet been investigated. Using systematic review case studies from environmental science, we investigated the utility of GS in systematic reviews and in searches for grey literature. Our findings show that GS results contain moderate amounts of grey literature, with the majority found on average at page 80. We also found that, when searched for specifically, the majority of literature identified using Web of Science was also found using GS. However, our findings showed moderate/poor overlap in results when similar search strings were used in Web of Science and GS (10-67%), and that GS missed some important literature in five of six case studies. Furthermore, a general GS search failed to find any grey literature from a case study that involved manual searching of organisations' websites. If used in systematic reviews for grey literature, we recommend that searches of article titles focus on the first 200 to 300 results. We conclude that whilst Google Scholar can find much grey literature and specific, known studies, it should not be used alone for systematic review searches. Rather, it forms a powerful addition to other traditional search methods. In addition, we advocate the use of tools to transparently document and catalogue GS search results to maintain high levels of transparency and the ability to be updated, critical to systematic reviews.

Evidence for benefits from treating cervical ectopy: literature review

Directory of Open Access Journals (Sweden)

Luís Carlos Machado Junior

Full Text Available CONTEXT AND PURPOSE: Uterine cervical ectopy (cervical erosion is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. The purpose of this study was to review the medical literature for evidence regarding benefits from treating cervical ectopy. METHODS: The following databases were reviewed: Medical Literature Analysis and Retrieval System Online (Medline, Excerpta Medica Database (Embase, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs and Cochrane Library databases. In addition, six medical textbooks were consulted. RESULTS: The review showed that: 1 there is probably an association between ectopy and higher risk of Chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4 there is probably an association between ectopy and cervical intraepithelial neoplasia; 5 there is an association between ectopy and mucous discharge and nocturia; and 6 there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. CONCLUSIONS: 1 No data were found in the medical literature to support routine treatment for ectopy; 2 Treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3 Further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

Nonhuman primate dermatology: a literature review

Science.gov (United States)

Bernstein, Joseph A.; Didier, Peter J.

2015-01-01

In general, veterinary dermatologists do not have extensive clinical experience of nonhuman primate (NHP) dermatoses. The bulk of the published literature does not provide an organized evidence-based approach to the NHP dermatologic case. The veterinary dermatologist is left to extract information from both human and veterinary dermatology, an approach that can be problematic as it forces the clinician to make diagnostic and therapeutic decisions based on two very disparate bodies of literature. A more cohesive approach to NHP dermatology – without relying on assumptions that NHP pathology most commonly behaves similarly to other veterinary and human disease – is required. This review of the dermatology of NHP species includes discussions of primary dermatoses, as well as diseases where dermatologic signs represent a significant secondary component, provides a first step towards encouraging the veterinary community to study and report the dermatologic diseases of nonhuman primates.

Blake, Marianne; Mitchell, Gary

2016-01-20

Aim To present a narrative review of the empirical literature on the use of horticultural therapy in dementia care. Method A comprehensive literature search, conducted in December 2014, resulted in the selection of 15 primary research articles for review. Of these, three used qualitative methods, five used quantitative methods and seven used mixed methodology. The articles were critically appraised, and the narrative synthesis used a thematic approach whereby prominent themes from the articles were grouped to form representative themes. Findings Three main themes emerged from the narrative synthesis: the emotional health of people living with dementia, their perceived self-identity and their levels of engagement. Conclusion Horticultural therapy can be beneficial. At a macro-level, it is an inexpensive therapy that does not require specialist training to deliver. At a micro-level, it enhances the wellbeing of people living with dementia. Recommendations are made to promote access to appropriate horticultural therapy for people living with dementia, and for further research in this area.

Retrospective and prospective cohort studies suggest that central nervous system involvement occurs in approximately 0.5 % of patients with advanced Hodgkin's lymphoma. The isolated primary intracranial manifestation of Hodgkin's lymphoma is an extremely rare finding, with few cases reported in the literature. Little is known about the optimal treatment and prognosis of these tumors. Here, we present a case report with a review of the literature. A 47-year-old Caucasian man with persistent frontal headache and unspecific vertigo for half a month was diagnosed with nodular space-occupying lesions in the cerebellum. His medical history included multiple sclerosis, which was treated for 20 years with the immunosuppressive drug azathioprine. Further staging revealed no additional lesions suspected of being malignant. The patient underwent total tumor resection. Immunohistopathological examination showed Epstein-Barr virus-associated classic Hodgkin's lymphoma. Diagnostic bone marrow punction excluded lymphoma involvement of the bone marrow. The patient had no B symptoms. Consequently, the patient was classified as having stage I E A disease according to the Modified Ann Arbor Classification of Hodgkin Lymphoma and received systemic chemotherapy followed by radiation therapy for the former cerebellar tumor region. He was in complete clinical remission at the last follow-up 9 months after the initial diagnosis. This case report and literature review suggest that multimodal treatment leads to a remarkable clinical outcome in Hodgkin's lymphoma with intracranial involvement. (orig.) [de

Summary This paper reviews the literature examining the relationship between women’s empowerment and contraceptive use, unmet need for contraception and related family planning topics in developing countries. Searches were conducted using PubMed, Popline and Web of Science search engines in May 2013 to examine literature published between January 1990 and December 2012. Among the 46 articles included in the review, the majority were conducted in South Asia (n = 24). Household decision-making (n = 21) and mobility (n = 17) were the most commonly examined domains of women’s empowerment. Findings show that the relationship between empowerment and family planning is complex, with mixed positive and null associations. Consistently positive associations between empowerment and family planning outcomes were found for most family planning outcomes but those investigations represented fewer than two-fifths of the analyses. Current use of contraception was the most commonly studied family planning outcome, examined in more than half the analyses, but reviewed articles showed inconsistent findings. This review provides the first critical synthesis of the literature and assesses existing evidence between women’s empowerment and family planning use. PMID:28069078

Social science literature on the environment: review and prospects for energy studies. A preliminary literature survey

Energy Technology Data Exchange (ETDEWEB)

Sommers, P.

1975-01-01

Much of the social science literature on environment is of recent origin and represents the response of the social science research community to a complex societal problem in which technology is a major factor. Energy represents another such problem to which the social science research community is now turning its attention. Because energy problems and environment problems have some similarities and because energy-conversion processes have large effects on the environment, a review of the social science literature on environment was undertaken. The purposes of this review are as follows: (1) to study the possible utility in energy research of some of the concepts developed in social science research on the environment; (2) to study the possible utility in energy research of some of the methodologies utilized in social science research on the environment; and (3) to study the extent to which the results of social science research on the environment have contributed to the development of policy. The first two items above receive major attention in this preliminary literature survey. 50 references.

"I sleep better at night:" How peer review of radiation treatment plans indirectly improves quality of care across radiation treatment programs.

Brundage, Michael D; Hart, Margaret; O'Donnell, Jennifer; Reddeman, Lindsay; Gutierrez, Eric; Foxcroft, Sophie; Warde, Padraig

Peer review of radiation oncology treatment plans is increasingly recognized as an important component of quality assurance in radiation treatment planning and delivery. Peer review of treatment plans can directly improve the quality of those plans and can also have indirect effects on radiation treatment programs. We undertook a systematic, qualitative approach to describing the indirect benefits of peer review, factors that were seen to facilitate or act as barriers to the implementation of peer review, and strategies to address these barriers across a provincial jurisdiction of radiation oncology programs (ROPs). Semistructured qualitative interviews were held with radiation oncology department heads and radiation therapy managers (or delegates) in all 14 ROPs in Ontario, Canada. We used a theoretically guided phenomenological qualitative approach to design and analyze the interview content. Themes were recorded by 2 independent reviewers, and any discordance was resolved by consensus. A total of 28 interviews were completed with 32 interviewees. Twenty-two unique themes addressed perceived benefits of peer review, relating to either peer review structure (n = 3), process (n = 9), or outcome (n = 10). Of these 22 themes, 19 related to indirect benefits to ROPs. In addition, 18 themes related to factors that facilitated peer review activities and 30 themes related to key barriers to implementing peer review were identified. Findings were consistent with, and enhanced the understanding of, previous survey-based assessments of the benefits and challenges of implementing peer review programs. Although challenges and concerns regarding the implementation of peer review were evident, the indirect benefits to radiation programs are numerous, far outweigh the implementation challenges, and strongly complement the direct individual-patient benefits that result from peer review quality assurance of radiation treatment plans.

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

This systematic review provides an overview of the literature published on Releasing Time to Care: The Productive Ward between 2005 and June 2011. Releasing Time to Care: The Productive Ward programme was developed by the NHS Institute for Innovation and Improvement and launched in England in 2007. The programme comprises thirteen modules that aim to increase time for direct patient care, improve the patient and staff experience and make changes to the ward environment to improve efficiency. A systematic literature review. The terms 'Releasing Time to Care' and 'Productive Ward' were applied to key healthcare databases; CINAHL, Medline, Science Direct, ProQuest, Health Business Elite, British Nursing Index, Embase, Health Management Information Consortium and PsychInfo. All papers were read and subject to a quality assessment. The literature search identified 95 unique sources. A lack of research on The Productive Ward programme meant it was necessary to include non-empirical literature. In total, 18 articles met the inclusion criteria. Seven key themes were identified: the patient and staff experience, direct care time, patient safety, financial impact, embedding and sustainability, executive support and leadership, and common barriers and determinants of success. It also highlighted areas that require further exploration such as long-term sustainability of the programme and consistent data measurement between organisations. The review tentatively reports how The Productive Ward programme has been used to transform nursing practice for the benefit of patients and frontline staff, and how it resulted in cost savings. The literature review identified a potential positive results bias in the current literature whereby favourable outcomes were reported. This paper summarises the types of evidence and current literature on The Productive Ward providing a reference for frontline staff implementing the programme. © 2013 Blackwell Publishing Ltd.

Radiation recall dermatitis (RRD) refers to an acute inflammatory skin reaction appearing on a previously irradiated area following the systemic administration of a reaction-triggering agent. Despite various hypotheses, the pathomechanism of RRD appears complex and is still not fully understood. In addition, no clinical guidelines exist concerning whether drug treatment should be continued upon manifestation of an associated radiation recall phenomenon. We present the case of a patient with docetaxel-induced RRD, which was successfully treated with topical steroids and systemic antihistamines; re-challenge to docetaxel did result in very mild remanifestation of skin reactions. (orig.) [German] Die Strahlen-Recall-Dermatitis (RRD) ist eine akute entzuendliche Reaktion der Haut in einem zuvor bestrahlten Areal als Reaktion auf die systemische Applikation eines triggernden Agens. Der zugrunde liegende Pathomechanismus ist bisher nicht vollstaendig geklaert. Ferner gibt es keine klinischen Leitlinien dazu, ob bei einem assoziierten RRD-Phaenomen die medikamentoese Behandlung fortgesetzt werden sollte oder nicht. Vorgestellt wird ein Fall von Docetaxel-induzierter RRD, welche erfolgreich mit topischen Steroiden und systemischen Antihistaminika behandelt wurde. Eine erneute Docetaxel-Exposition des Patienten ging mit einer sehr milden Remanifestation der kutanen Effloreszenzen einher. (orig.)
