  2. Literature review :

    SciTech Connect

    Dwyer, Stephen F.

    2013-03-01

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    Parafunctional activities associated with the stomatognathic system include lip and cheek chewing, nail biting, and teeth clenching. Bruxism can be classified as awake or sleep bruxism. Patients with sleep bruxism are more likely to experience jaw pain and limitation of movement, than people who do not experience sleep bruxism. Faulty occlusion is one of the most common causes of bruxism that further leads to temporomandibular joint pain. Bruxism has been described in various ways by different authors. This article gives a review of the literature on bruxism since its first description. PMID:25628497

    2012-04-01

    Compadrazgo, "coparenthood," is a traditional ritual fictive kinship system that provides a network of mutually supportive relationships in the Mexican American culture. A literature search of CINAHL, Medline, PsychoInfo, and Web of Science was used to identify peer-reviewed journals and original sources. Keywords included comadre, compadrazgo, fictive kin, social support, Mexican, and Mexican American. Additional resources were identified through a focused review of references. Findings from this study indicate knowledge about compadrazgo, is limited to the social organization, historical practices, and a preliminary description of the compadres role. Minimal information is available about the relationship between compadrazgo, and health, and variations in roles and responsibilities of compadrazgo, participants. Frequency of enactment of compadrazgo, responsibilities and barriers to the enactment of social support by compadres remain unknown. Variations in practice have not been explored. Nursing implication include the recommended ways that compadrazgo, can be encouraged or promoted in patient care. PMID:22267550

  9. CROSSFLOW FILTRATON: LITERATURE REVIEW

    SciTech Connect

    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

  19. Working postures: a literature review.

    PubMed

    Vieira, Edgar Ramos; Kumar, Shrawan

    2004-06-01

    Working postures are addressed in many papers in the ergonomics field but, surprisingly, scientific literature dealing with working posture itself is not common; knowledge has been elusive. This article reviews the working postures literature. Selected papers published in the English language before March 2003 including the phrase "working postures" in the title, abstract, or keywords were searched in the PubMed, Scirus, and Science Direct databases and reviewed. The literature provides evidence that working postures and musculoskeletal health are related. This relationship is supported by the overexertion, differential fatigue, and cumulative load theories of musculoskeletal injuries' precipitation. Goniometers, inclinometers, photographic techniques, electrogoniometers, and video recording systems are the means that are most often used to measure working postures. Information about working postures need to be collected and analyzed in a more systematic way in order to contribute for a deeper understanding of the relationship between working postures and work-related musculoskeletal disorders. This information will help to improve the control and rehabilitation of these highly prevalent disorders.

    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

  1. REVIEW OF PLUTONIUM OXIDATION LITERATURE

    SciTech Connect

    Korinko, P.

    2009-11-12

    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 (<15 {micro}m), moderately sized particles (15 < x < 250 {micro}m) and large particles (> 250 {micro}m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for

  2. Improving intelligence: a literature review.

    PubMed

    Buschkuehl, M; Jaeggi, S M

    2010-05-01

    Intelligence is associated with performance on a wide range of cognitive tasks and is a reliable predictor for educational and professional success. Therefore, the development of effective training regimens that aim to improve intelligence is of high interest. In recent years, there has been accumulating evidence that certain interventions have a positive impact on intelligence. The aim of the present paper is to provide a literature review on such studies. Despite promising results, we conclude that there are still many unknown variables and that the mechanisms that underlie improvements in intelligence are not well understood. More work is needed in order to disentangle these involved processes and to further refine existing training regimens.

    Khan, L U R; Ahmed, J; Khan, S; Macfie, J

    2011-01-01

    Refeeding syndrome (RFS) describes the biochemical changes, clinical manifestations, and complications that can occur as a consequence of feeding a malnourished catabolic individual. RFS has been recognised in the literature for over fifty years and can result in serious harm and death. Crude estimates of incidence, morbidity, and mortality are available for specific populations. RFS can occur in any individual but more commonly occurs in at-risk populations. Increased awareness amongst healthcare professionals is likely to reduce morbidity and mortality. This review examines the physiology of RFS and describes the clinical manifestations. A management strategy is described. The importance of a multidisciplinary approach is emphasized.

    Goutam, Manish; Giriyapura, Chandu; Mishra, Sunil Kumar; Gupta, Siddharth

    2014-01-01

    Titanium has gained immense popularity and has successfully established itself as the material of choice for dental implants. In both medical and dental fields, titanium and its alloys have demonstrated success as biomedical devices. Owing to its high resistance to corrosion in a physiological environment and the excellent biocompatibility that gives it a passive, stable oxide film, titanium is considered the material of choice for intraosseous use. There are certain studies which show titanium as an allergen but the resources to diagnose titanium sensivity are very limited. Attention is needed towards the development of new and precise method for early diagnosis of titanium allergy and also to find out the alternative biomaterial which can be used in place of titanium. A review of available articles from the Medline and PubMed database was done to find literature available regarding titanium allergy, its diagnosis and new alternative material for titanium.

    2016-01-01

    Regeneration and tissue repair processes consist of a sequence of molecular and cellular events which occur after the onset of a tissue lesion in order to restore the damaged tissue. The exsudative, proliferative, and extracellular matrix remodeling phases are sequential events that occur through the integration of dynamic processes involving soluble mediators, blood cells, and parenchymal cells. Exsudative phenomena that take place after injury contribute to the development of tissue edema. The proliferative stage seeks to reduce the area of tissue injury by contracting myofibroblasts and fibroplasia. At this stage, angiogenesis and reepithelialization processes can still be observed. Endothelial cells are able to differentiate into mesenchymal components, and this difference appears to be finely orchestrated by a set of signaling proteins that have been studied in the literature. This pathway is known as Hedgehog. The purpose of this review is to describe the various cellular and molecular aspects involved in the skin healing process.

    Background and aims. An ideal root canal filling material should completely seal the entire root canal space and block communication between the root canal system and its surrounding tissues; it should also be nontoxic, noncarcinogenic, non-genotoxic, biocompatible, insoluble in tissue fluids and dimensionally stable. Bonding to dentin is a promising property, which can prevent leakage and improve the sealing ability of root canal filling materials. Resilon was developed and rec-ommended initially because the existing rootcanal filling materials did not bond to root canal dentin. Since its introduction in 2004, numerous reports have been published regarding various aspects of this material. The aim of this literature review is to present investigations regarding Resilon’s physical and chemical properties and leakage studies. Materials and methods. A review of the literature was performed by using electronic and hand searching methods for Resilon from May 2004 to April 2012. Results. There are many published reports regarding Resilon. The searchshowed that Resilon is composed of a parent polymer, polycaprolactone or Tone, which is a biodegradable aliphatic polyester, with filler particles consisting of bioactive glass, bismuth oxychloride and barium sulfate. It possesses some antibacterial and antifungal properties. It is a promising material for root canal filling. Despite the presence of numerous case reports and case series regarding these applications, there are few designed research studies on clinical applications of this material. Resilon has some drawbacks such as high cost. Conclusion. Resilon seals well and is a biocompatible material. However, more clinical studies are needed to confirm its efficacy compared with other materials. PMID:24082982

    PubMed

    Solares, Roberto; Romero, Maria Isabel

    2004-01-01

    Supernumerary premolars appear to be more common than previously estimated. The purpose of this report was to review most of the cases published in the dental literature since 1932. The authors found that supernumerary premolars occur 3 times more in males than in females, indicating a possible sex-linked inheritance, with the highest frequency of occurrence in the mandibular premolar region (74%). They are also the most common supernumerary teeth in the mandibular arch (7%), and their incidence is 1% (1 in 157)-much higher than previously reported. Maxillary supernumerary premolars were found to occur at a lower rate (26%). The possible mechanisms of development are described, with a localized hyperactivity of the dental lamina being the most widely accepted theory. Recurrence of supernumerary premolars after being surgically removed has been reported in 8% of the cases reviewed. Patients with a previous history of anterior conical or tuberculated supernumerary teeth at an early age have a 24% possibility of developing single or multiple supernumerary premolars at a later age. Early diagnosis and appropriate follow-up with panoramic radiographs is extremely important. Various treatment recommendations are also discussed. PMID:15460302

    SciTech Connect

    Negus-de Wys, Jane

    1992-09-01

    A literature review of the geopressured-geothermal habitat is summarized. Findings are presented and discussed with respect to the principal topics: Casual agents are both geological and geochemical; they include disequilibrium compaction of sediments, clay diagenesis, aquathermal pressuring, hydrocarbon generation, and lateral tectonic compression. The overall physical and chemical characteristics of the habitats are dictated by varying combinations of sedimentation rates, alteration mineralogy, permeability, porosity and pressure, temperature, fluid content and chemistry, and hydrodynamic flow. Habitat pressure seals are considered in terms of their formation processes, geologic characteristics, and physical behavior, including pressure release and reservoir pressure recharge on a geologic time scale. World-wide occurrence of geopressured-geothermal habitats is noted. The main thrust of this topic concerns the U.S.A. and Canada; in addition, reference is made to occurrences in China and indications from deep-sea vents, as well as the contribution of paleo-overpressure to habitat initiation and maintenance. Identification and assessment of the habitat is addressed in relation to use of hydrogeologic, geophysical, geochemical, and geothermic techniques, as well as well-logging and drill-stem-test data. Conclusions concerning the adequacy of the current state of knowledge and its applicability to resource exploration and development are set forth, together with recommendations for the thrust of future work.

    Im, Eun-Ok; Chang, Sun Ju

    2012-11-01

    As faculty members, we frequently find that first-year doctoral students in nursing are confused about how to conduct a systematic integrated literature review. This could be due to its vague definition and a lack of recent literature that provides directions for conducting a systematic integrated literature review. This article aims to provide directions for conducting a systematic integrated literature review by identifying the essential components of published literature reviews in nursing. To achieve this goal, the literature was searched by using the keywords nursing, systematic, and review in multiple databases. A total of 267 articles were selected and are included in this systematic integrated literature review. The articles were then sorted by study design and analyzed in six areas of interests. Finally, a practical guideline for conducting systematic integrated literature reviews is proposed based on the analysis of the literature.

    Psychological resilience is comprised of an adaptive functioning standard before the current and accumulated risks of life. Furthermore, it has a comprehensive range of psychological resources which are essential to overcome adversities, such as personal competences, self-beliefs and interpersonal control which interact with the social networks support. The objectives are to show the concepts of psychological resilience in elderly, relative to dominant theoretical models and the main data about psychological resilience in aging, found in an international and Brazilian review from 2007 to 2013. The descriptors "resilience, psychological resilience and aging", "resiliência e envelhecimento, velhice e velho", were used in PubMed, PsychInfo, SciELO and Pepsic databases. Fifty three international and eleven national articles were selected. The international articles were classified in four categories: psychological and social coping resources, emotional regulation before stressing experiences, successful resilience and aging and correlates, and resilience measures. The Brazilian articles were grouped in three: psychological and social resources, resilience in carers and theory review. Articles on psychological resources and on emotional regulation prevailed as key factors associated with psychological resilience in aging. PMID:26017950

    Abstract Introduction: We report the case of a multicentric Castleman disease (MCD) with initial renal involvement. Although the renal involvement in this case was typical of MCD, it constitutes a rare presentation of the disease, and in our case the renal manifestations led to the haematological diagnosis. Clinical Findings/Patient Concerns: The patient was admitted for fever, diarrhea, anasarca, lymphadenopathies and acute renal failure. Despite intravenous rehydration using saline and albumin, renal function worsened and the patient required dialysis. While diagnostic investigations were performed, right hemiplegia occurred. There was no anemia or thrombocytopenia. Diagnoses: Kidney biopsy was consistent with glomerular thrombotic microangiopathy (TMA). Lymph node histology was consistent with hyalin-vascular variant of Castleman disease. Outcomes: Given the renal and neurological manifestations of this MCD-associated TMA, the patient was treated with plasma exchange during one month, and six courses of rituximab, cyclophosphamide and dexamethasone. The evolution was favorable. Conclusion: Although rare, this diagnosis is worth knowing, as specific treatment has to be started as soon as possible and proved to be efficient in our case as well as in other reports in the literature.

    Introduction Professor Archibald Cochrane, after whom the Cochrane Collaboration is named, was influential in promoting evidence-based clinical practice. He called for "relevant, valid research" to underpin all aspects of healthcare. Systematic reviews of the literature are regarded as a high quality source of cumulative evidence but it is unclear how truly systematic they, or other review articles, are or 'how systematic is systematic?' Today's evidence-based review industry is a burgeoning mix of specialist terminology, collaborations and foundations, databases, portals, handbooks, tools, criteria and training courses. Aim of the review This study aims to identify uses and types of reviews, key issues in planning, conducting, reporting and critiquing reviews, and factors which limit claims to be systematic. Method A rapid review of review articles published in IJCP. Results This rapid review identified 17 review articles published in IJCP between 2010 and 2015 inclusive. It explored the use of different types of review article, the variation and widely available range of guidelines, checklists and criteria which, through systematic application, aim to promote best practice. It also identified common pitfalls in endeavouring to conduct reviews of the literature systematically. Discussion Although a limited set of IJCP reviews were identified, there is clear evidence of the variation in adoption and application of systematic methods. The burgeoning evidence industry offers the tools and guidelines required to conduct systematic reviews, and other types of review, systematically. This rapid review was limited to the database of one journal over a period of 6 years. Although this review was conducted systematically, it is not presented as a systematic review. Conclusion As a research community we have yet to fully engage with readily available guidelines and tools which would help to avoid the common pitfalls. Therefore the question remains, of not just IJCP but

    During gestation, many microorganisms can infect the fetus, causing severe birth defects. Such organisms and the resulting clinical syndromes have been categorized as TORCH infections, a useful acronym referring to Toxoplasma gondii, other microorganisms (like syphilis), rubella virus, cytomegalovirus, and herpesviruses. Since dental patients typically report pregnancy or previous infections as part of their health history, and TORCH infections can manifest oral symptoms, the dentist is in a position to act as an educator and screener for these infections. This article reviews TORCH agents for dentists to help the clinician in educating pregnant patients about the risks these infections pose to the fetus. The authors also note oral symptoms related to these infections. PMID:15552342

  14. Vicarious learning: a review of the literature.

    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.

    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.

  20. Defining professional nursing accountability: a literature review.

    PubMed

    Krautscheid, Lorretta C

    2014-01-01

    Professional nursing accountability is described by both professional nursing organizations and nursing education credentialing agencies as a core aspect that underpins professional nursing practice. Although accountability is foundational to professional practice, a review of the literature revealed no consistent language or definition regarding professional nursing accountability. Instead, the literature itself reveals that professional nursing accountability is challenging to both describe and define. The ambiguity surrounding how to define professional nursing accountability contributes to challenges associated with both teaching and evaluating student nurse accountability within nursing education curricula. This article provides a reliable and comprehensive definition of professional nursing accountability derived from a synthesis of the literature. Recommendations for nursing education practice and recommendations for nursing education research are proposed. PMID:24503314

    Hanks, Brian; Fitzgerald, Sue; McCauley, Renée; Murphy, Laurie; Zander, Carol

    2011-06-01

    This article provides a review of educational research literature focused on pair programming in the undergraduate computer science curriculum. Research suggests that the benefits of pair programming include increased success rates in introductory courses, increased retention in the major, higher quality software, higher student confidence in solutions, and improvement in learning outcomes. Moreover, there is some evidence that women, in particular, benefit from pair programming. The literature also provides evidence that the transition from paired to solo programming is easy for students. The greatest challenges for paired students appear to concern scheduling and partner compatibility. This review also considers practical issues such as assigning partners, teaching students to work in pairs, and assessing individual contributions, and concludes with a discussion of open research questions.

    2000-10-01

    The ability to determine dental casualty rates for the Australian Defence Force in a given situation is vital for military planners. This article reviews the literature and the available Australian Defence Force data on the subject to give some guide to planners. The review found the studies to be fairly consistent in that a well-prepared dentally fit force can expect 150 to 200 dental casualties per 1,000 soldiers per year. If the force were less prepared, as in the case of a reserve call out, this figure would be likely to increase; in the extreme case of an ill-prepared force or a force assisting in humanitarian aid, the emergency rate could be five times that figure. The literature also indicates a change in the nature of dental casualties. Although maxillofacial cases have remained steady at 25%, dental disease has decreased and endodontic cases have had a corresponding increase.

  7. Maternal Depression and Childhood Aggression: Literature Review

    PubMed Central

    Hendricks, Katherine; Liu, Jianghong

    2012-01-01

    Introduction Childbearing depression (CBD) and childhood aggression are serious and international problems that encumber public health. Although maternal depression has received much attention in the literature in the last three decades, clinically it remains under-diagnosed and under-treated, especially during pregnancy. As a result, many mothers and families are left to suffer its long-lasting physical and psychosocial effects. This article's aim is to review the current literature on whether CBD increases the likelihood of childhood aggression in children ages six years and younger. Methods Using keywords, an electronic search was performed using Cumulative Index of Nursing and Allied Health, PsycINFO, and PubMed databases. Search limits included the following: 2000-2010, English, peer-review, human, All Child: 0-18. From more than 2,000 search results, 13 articles were reviewed based on relevance to paper's inquiry and sample size greater than 50. Results In all, the articles agreed that depression in women increases the likelihood of early childhood aggression by causing negative parenting behaviors. However, this finding is tempered by a number of weaknesses in the quality of articles reviewed and by the complexity of the topic. Conclusion More research is needed to determine the etiology and interplay of mediating factors between CBD and childhood aggression. This could inform the study and implementation of effective and early prevention, screening, and treatment measures and programs for maternal depression and childhood aggression. PMID:22739482

    2016-01-01

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

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.

    2010-01-01

    Objective: The objective of this systematic literature review is to review current scientific knowledge on the definition of and the indications for maternal/obstetric intensive care (MIC). Methods: We conducted a extensive search in OVID MEDLINE, EMBASE, COCHRANE, CINHAL and CEBAM using the keywords: maternal/obstetric intensive care, subacute care, intermediate care, postacute care, critical care, sub intensive care, progressive patient care, postnatal care, perinatal care, obstetrical nursing, neonatology, pregnancy, maternal mortality/morbidity and pregnancy complication. A total of 180 articles and one guideline were identified and supplemented by a hand search. After title, abstract and full text evaluation, the articles and guideline were subjected to critical appraisal. Results: Out of 180 potentially relevant articles, we identified 44 eligible articles of which 14 relevant MIC-articles of relatively good quality were selected. The concept ‘maternal intensive care’ was not found elsewhere, “high-dependency care” and “obstetrical intermediate care” appeared to be best comparable to what is understood as a MIC-service in Belgium. This thorough literature search resulted in a limited amount of scientific literature, with most studies retrospective observational tertiary centre based. No clear definition and admission criteria for maternal intensive care were found. Conclusion: This systematic literature review revealed that 1) there is no standard definition of maternal intensive care and 2) that admission criteria to a MIC unit differ widely. Further research is needed to create an evidence-based triage system to help clinicians attribute women to the appropriate level of care and thus stimulate an efficient utilization of maternal/obstetric intensive care services.

    Objective: To review the literature regarding the role of laparoscopy during pregnancy, particularly adnexal mass and non-obstetric surgery, incorporating the results of a series of 9 cases of laparoscopy during pregnancy at our centers. Materials and Methods: A Medline search was performed to review the literature, and the reference lists provided by those articles were further explored for citations regarding laparoscopic adnexal surgery, appendectomy, and cholecystectomy. Our series of 9 patients consisted of pregnant patients with adnexal mass or acute abdomen who would otherwise have undergone exploratory laparotomy. Follow-up data for these 9 cases were collected by office visits, inquiry to the primary referring physicians, and telephone calls to the patient. Results: The literature search yielded 42 additional cases of operative pelvic laparoscopy and 51 cases of abdominal operative laparoscopy (cholecystectomy and appendectomy). The publications, particularly regarding cholecystectomy, were supportive of the laparoscopic approach during pregnancy. All of the patients in our series had favorable outcomes. Conclusions: Advanced operative laparoscopy has been successfully performed for certain indications during pregnancy. PMID:9876642

    Kolber, Morey J.; Salamh, Paul A.

    2013-01-01

    Background and Purpose: Meralgia Paresthetica (MP) is a nerve entrapment which may cause pain, paresthesias, and sensory loss within the distribution of the lateral cutaneous nerve of the thigh. When the differential diagnosis of lateral or anterolateral thigh pain is inconclusive, MP should be considered as a potential source. MP produces similar signs and symptoms as those associated with more common diagnoses such as lumbar spine pathology. This clinical commentary will review the most relevant literature on MP with an emphasis on recognition and management of this condition. Description of Topic with Related Evidence: The authors reviewed the most relevant published literature on MP from 1970 to 2013 located using the databases PubMed, CINAHL, and Proquest. Discussion/Relation to Clinical Practice: MP still remains a diagnostic challenge since it can mimic other common diagnoses. Understanding the current literature surrounding the diagnosis and treatment of MP is essential for clinicians practicing in the outpatient environment. The consensus on the most effective non‐surgical and surgical interventions is still limited, as is the research on physical therapy interventions for this condition. Perhaps the lack of research and global consensus represents a knowledge deficit that makes MP a challenge to diagnose and successfully treat. Future collaborative studies are needed to improve the clinical diagnostics and understanding of interventions for this pathology. Level of Evidence: 5 PMID:24377074

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

    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.

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

    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.

    2013-01-01

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

    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

    Risk control on project schedule is one of the focus problems in the academic circle and the practical area all the time. Lots of research about risk control on project schedule have been fulfilled and many achievements have appeared in recent several decades. The literature on the techniques of schedule uncertainty control was reviewed. A summary analysis on those chievements is presented such as CPM, PERT, MC, BBN, and so on and in light of that summary analysis a deep discussion in terms of advantages and disadvantages of existing research has been analyzed, so that researchers can continue to refine their research.

    Pseudocirrhosis describes morphological changes of the liver that closely mimic cirrhosis, without the typical histopathological changes seen in cirrhosis. It most commonly occurs in patients with metastatic breast cancer, although it has been reported in other malignancies as well. Like in cirrhosis, portal hypertension is often seen in patients with pseudocirrhosis. Pseudocirrhosis is a rare but important complication of metastatic cancer. In this case series and literature review, we describe 6 patients with hormone-receptor-positive metastatic breast cancer. We report the significant morbidity associated with pseudocirrhosis in the course of treatment in patients with metastatic breast cancer.

    This article is a literature review of the aspects of military parachuting related to occupational medicine and focuses on 'conventional' military static line parachuting using a round parachute. The analysis of injuries resulting from military parachuting provide an excellent example of military occupational medicine practice. The techniques of military parachuting are described in order to illustrate the potential mechanisms of injury, and a number of 'classical' parachuting injuries are described. Finally some recommendations are made for the recording of parachute injuries which would assist in the international comparison of injury rates and anatomical distribution. PMID:10451583

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

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

    Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed journals. A review of pertinent literature was conducted using the PubMed database, and data obtained were categorized into sections in terms of relevant topics. Studies conducted in recent years highlighted the antimicrobial potential of photodynamic therapy in endodontics. However, most of these studies were not able to confirm a significant improvement in root canal disinfection for photodynamic therapy as a substitute for current disinfection methods. Its indication as an excellent adjunct to conventional endodontic therapy is well documented, however. Data suggest the need for protocol adjustments or new photosensitizer formulations to enhance photodynamic therapy predictability in endodontics. PMID:25719896

    ABSTRACT Objectives This review article discusses the host response in apical periodontitis with the main focus on cytokines, produced under this pathological condition and contributing to the degradation of periradicular tissues. The pace of research in this field has greatly accelerated in the last decade. Here we provide an analysis of studies published in this area during this period. Material and methods Literature was selected through a search of PubMed electronic database. The keywords used for search were pathogenesis of apical periodontitis cytokines, periapical granuloma cytokines, inflammatory infiltrate apical periodontitis. The search was restricted to English language articles, published from 1999 to December 2010. Additionally, a manual search in the cytokine production, cytokine functions and periapical tissue destruction in the journals and books was performed. Results In total, 97 literature sources were obtained and reviewed. The topics covered in this article include cellular composition of an inflammatory infiltrate in the periapical lesions, mechanisms of the formation of the innate and specific immune response. Studies which investigated cytokine secretion and functions were identified and cellular and molecular interactions in the course of apical periodontitis described. Conclusions The abundance and interactions of various inflammatory and anti-inflammatory molecules can influence and alter the state and progression of the disease. Therefore, periapical inflammatory response offers a model, suited for the study of many facets of pathogenesis, biocompatibility of different materials to periapical tissues and development of novel treatment methods, based on the regulation of cytokines expression PMID:24421998

    Statement of problem: Evidence is limited on the efficacy of zirconia-based fixed dental prostheses. Objective: To carry out a literature review of the behavior of zirconium oxide dental restorations. Material and Methods: This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words “zirconium oxide,” “zirconia,” “non-metal restorations,” “ceramic oxides,” “veneering ceramic,” “zirconia-based fixed dental prostheses”. Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included. Results: Clinical studies have revealed a high rate of fracture for porcelain-veneered zirconia-based restorations that varies between 6% and 15% over a 3- to 5-year period, while for ceramo-metallic restorations the fracture rate ranges between 4 and 10% over ten years. These results provoke uncertainty as to the long-term prognosis for this material in the oral medium. The cause of veneering porcelain fractures is unknown but hypothetically they could be associated with bond failure between the veneer material and the zirconia sub-structure. Key words:Veneering ceramic, zirconia-based ceramic restoration, crown, zirconia, tooth-supported fixed prosthesis. PMID:24596638

    This paper reviews the literature on reference pricing (RP) in pharmaceutical markets. The RP strategy for cost containment of expenditure on drugs is analyzed as part of the procurement mechanism. We review the existing literature and the state-of-the-art regarding RP by focusing on its economic effects. In particular, we consider: (1) the institutional context and problem-related factors which appear to underline the need to implement an RP strategy; i.e. its nature, characteristics and the sort of health care problems commonly addressed; (2) how RP operates in practice; that is, how third party-payers (the insurers/buyers) have established the RP systems existing on the international scene (i.e. information methods, monitoring procedures and legislative provisions); (3) the range of effects resulting from particular RP strategies (including effects on choice of appropriate pharmaceuticals, insurer savings, total drug expenditures, prices of referenced and non-referenced products and dynamic efficiency; (4) the market failures which an RP policy is supposed to address and the main advantages and drawbacks which emerge from an analysis of its effects. Results suggest that RP systems achieve better their postulated goals (1) if cost inflation in pharmaceuticals is due to high prices rather than to the excess of prescription rates, (2) when the larger is the existing difference in prices among equivalent drugs, and (3) more important is the actual market for generics.

    Tobacco is a preventable cause of morbidity and mortality across the world. A recently infamous way of smoking tobacco is shisha. Shisha smoking is also known as water pipe, hookah and Narghile smoking. The percentage of shisha smokers is on the rise rapidly spanning the globe. A literature review was conducted to identify all evidence on the epidemiological variations and health effects of shisha smoking. “Pub med” is used as a searching tool to identify all relevant empirical studies conducted worldwide. A qualitative overview of evidence is presented. Exposure to Shisha smoking is significantly associated with low infant weight, heart rate variations, hyperglycemia and hypertriglyceridemia. Increased risk of carcinoma is also leagued with it including carcinomas of the pancreas and lung being at the forefront. In conclusion, this review identifies grounds of several adverse conditions being associated with the habit of shisha smoking. It also evaluates the relevant epidemiological variations around the globe. The review culminates in the importance of enlightening shisha smokers regarding its deleterious effects. PMID:24708750

    Objective: To highlight the clinical and radiologic features and management of craniofacial fibrous dysplasia with review of literature. Materials and Methods: A retrospective review of 6 patients who underwent surgical treatment in a tertiary healthcare centre was done using the parameters of patients' details, clinical features, radiological findings, management and postoperative review. Results: Of the six patients, 3 females and 2 males were in the 2nd decade of life and 1 male in the 1st decade of life. The disease was restricted to maxilla in 3 patients, involved the temporal and frontal bones in addition to maxilla in one, involved the frontal bone in one patient and involved frontal and parietal bones in one patient. The primary reason for seeking treatment in all the 6 cases was facial deformity. There was absence of pain in all 6 cases. For surgical treatment in all three cases involving the maxilla, the approach was intraoral while bicoronal approach was used for the other three cases. Treatment consisted of surgical contouring and reshaping the area. All cases were followed up over a period of 2 years with no signs of recurrence. Conclusion: Treatment of craniofacial fibro-osseous lesions is highly individualized. Most cases of craniofacial fibrous dysplasia manifest as swellings that cause facial deformity and surgical recontouring after cessation of growth seems to provide the best results. PMID:23662263

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

    This systematic review of the literature assessed the impact of a postdischarge telephone call on patient outcomes. Nineteen articles met inclusion criteria. Data were extracted and an evidence table was developed. The content, timing, and professional placing the call varied across studies. Study strength was low and findings were inconsistent. Measures varied across studies, many sample sizes were small, and studies differed by patient population. Evidence is inconclusive for use of phone calls to decrease readmission, emergency department use, patient satisfaction, scheduled and unscheduled follow-up, and physical and emotional well-being. Among these studies, there was limited support for medication-focused calls by pharmacists but no support for decreasing readmission. Health care providers benefited from feedback but did not need to place the call to realize this benefit. Inpatient nurses were unable to manage the volume of calls. There was no standardized approach to the call, training, or documentation requirements.

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

    2016-01-01

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

    Electronic whiteboards are being introduced into hospitals to communicate real-time patient information instantly to staff. This paper provides a preliminary review of the current state of evidence for the effect of electronic whiteboards on care processes and patient outcomes. A literature search was performed for the dates 1996 to 2014 on MEDLINE, EMBASE, IEEE Xplore, Science Direct, and the ACM Digital Library. Thirteen papers, describing 11 studies, meeting the inclusion criteria were identified. The majority of studies took place in the Emergency Department. While studies looked at the impact of electronic whiteboards on the process of care, there is an absence of evidence concerning impact on patient outcomes. There is a need for robust research measuring the impact of electronic whiteboards on inpatient care.

    The resurgence of airships has created a need for dynamics models and simulation capabilities adapted to these lighter-than-air vehicles. However, the modeling techniques for airship dynamics have lagged behind and are less systematic than those for fixed-wing aircraft. A state-of-the-art literature review is presented on airship dynamics modeling, aiming to provide a comprehensive description of the main problems in this area and a useful source of references for researchers and engineers interested in modern airship applications. The references are categorized according to the major topics in this area: aerodynamics, flight dynamics, incorporation of structural flexibility, incorporation of atmospheric turbulence, and effects of ballonets. Relevant analytical, numerical, and semi-empirical techniques are discussed, with a particular focus on how the main differences between lighter-than-air and heavier-than-air aircraft have been addressed in the modeling. Directions are suggested for future research on each of these topics.

    In his comprehensive monograph on plague, published by WHO in 1954, Dr Pollitzer pointed out that despite the marked drop in the incidence of this disease in recent years, he considered it impossible for various reasons to be complacent about the situation. Since this monograph appeared, plague has shown a truly spectacular decrease, but in case this is partly the outcome of a natural periodicity of the infection, the author still feels that the disease ”should be given continued attention by those interested in global public health”. To this end he summarizes here the latest information on the subject, his review covering not only works published since 1954, but also some earlier literature (particularly from the USSR) which was not available to him at the time of preparation of his monograph.

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

A systematic review of the literature was conducted, with articles being searched in the databases LILACS and SciELO, from the key words: audit, nursing, quality health care and nursing supervision. The sample consisted of ten works. The analyzed publications describe the main distortions and non-conformities found in nursing records, relating them mainly with the quality of nursing care and with the financial damage to the institutions. The publications also include the administrative role of the nurse, especially her/his leadership role in the team of nursing; and nursing audit as an educational process. PMID:22460497

    Mozart ear is a congenital auricular deformity, which is mainly characterized by a bulging appearance of the anterosuperior portion of the auricle, a convexly protruded cavum conchae, and a slit-like narrowing of the orifice of the external auditory meatus. It is said to be uncommon, and because no one has yet fully described neither the disease nor the treatment, the concept of Mozart ear has not been unified. This report describes a case of a 13-year-old girl presented with an unusual congenital deformity which showed the features of Mozart ear. It is an extremely rare deformity that only about 4 clinical cases have been reported in medical literature thereby a treatment method has not been fully discussed. For surgical correction of our cases, we excised deformed conchal cartilage, turned it over, regrafted, and maintained a cosmetically positive result. We also reviewed and described the origin, current concept, and treatment method of Mozart ear.

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

    Subarachnoid hemorrhage represents a serious disease with high mortality and morbidity. Two important areas are becoming the central research interest of subarachnoid hemorrhage: cerebral vasospasm and early brain injury. The authors have reviewed the major contributions in experimental subarachnoid hemorrhage documented in the medical literature in the past 5 years. Treatments interfering with nitric oxide - or endothelin-pathways continue to show antispasmotic effects in experimental models of subarachnoid hemorrhage. Inflammation and oxidative stress play a vital role in the pathophysiology of cerebral vasospasm. Apoptosis, a relevant cause of early brain injury after subarachnoid hemorrhage, also underline the etiology of cerebral vasospasm. Future research studies will continue to elucidate the pathophysiological pathways and treatment modalities targeting cerebral vasospasm and early brain injury, enabling an improvement in outcome for patients with subarachnoid hemorrhage.

    This paper has reviewed the literature on the methods of cavity preparation. The different methods are summarised in Table 1. Nowadays rotary instruments are accepted as standard for cavity preparation. The limitation of using a rotary instrument is the iatrogenic damage to adjacent teeth. Therefore some of the hand instruments remained an essential part of quality restorative dentistry. In order to reduce iatrogenic injury oscillating instruments had been developed. The oscillating instruments change the rotary movement into an oscillating movement and copy the shape of the working tip through an abrasive medium to the tooth surface. The abrasive medium is generally diamond. A new possibility in tooth preparation is the Er:YAG laser. It can be used for both cavity preparation and caries removal. The chemo-mechanical caries removal means the selective chemical softening is followed by the mechanical removing of carious dentin.

    A literature review was carried out focusing on the main factors associated with suicidal ideation, attempts and completed suicide in elders. The following databases were searched: MEDLINE, PsychINFO, SciELO and Biblioteca Virtual em Violência e Saúde da BIREME (BIREME's Violence and Health Virtual Library), referring to the period from 1980 to 2008. Fifty-two references were selected and analyzed. They showed a strong relationship among suicide ideation, attempt and completion in elderly individuals, which results from the interaction of complex physical, mental, neurobiological and social factors. Suicide associated with depression in the elderly can be prevented, provided the person is properly treated. In Brazil, it is necessary to invest in research, given the persistent increase in suicide rates among aged people, especially among males.

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

    Renal leiomyomas are rare benign tumours of the kidney originating from muscle cells. They are usually found by an autopsy, whether the patient is asymptomatic or has symptoms (i.e., abdominal/flank pain, hematuria, palpable mass). Today the widespread use of ultrasonography and computed tomography has increased the detection of clinically asymptomatic renal leiomyomas. The differential diagnosis between leiomyomas and other malignant lesions (above all renal cell carcinoma or leiomyosarcoma) is still possible by histological examination. Radiological examinations are not sufficient for the differential diagnosis. Renal leiomyomas have no aggressive behaviour and they usually do not metastasize. The prognosis, after surgery, is excellent without recurrence. We report a case of leiomyoma in a 31-year-old man who presented hematuria and flank pain. We also review the literature and provide a summary of clinical, radiological and histological features of renal leiomyomas. PMID:22511443

    Internet and particularly the so-called Web 2.0 are powerful tools of communication characterized by high user participation in the creation of content through various sites, such as those of social networking, where Facebook is the best known and most widely used. The aim of the present paper is to review the literature on the use of Facebook in health care. The international scientific literature of the past 10 years has been collected by major databases online. From the research were identified 262 articles of which 57 are considered relevant. The articles are schematically divided into three categories according to the topic: use of Facebook for psychosocial support for communication, for doctor-patient relationship, for institutional communication. The authors have identified the critical aspects and the possibility of using this tool in the communication and relationship between patients and health professionals. Despite the presence of critical issues, the use of social media is to be considered with interest and is worthy of study and research in the clinical setting. It should at the same time that health professionals are aware of the risks associated with the use of social networking but also trained in the use of the potential of these virtual tools that cannot replace real interactions but can support them.

    Abstract Nocardia are Gram-positive filamentous bacteria responsible for infections ranging from opportunistic life-threatening disseminated diseases to chronic skin and soft-tissue infections. Even if virtually all organs can be infected, articular involvement is rare. Therefore, we report 3 recent cases and performed a literature review of cases of Nocardia arthritis in order to describe clinical features, therapeutic challenges, and outcome of these patients. Among 34 patients (31 in the literature plus our 3 cases), 21 (62%) were due to hematogenous dissemination, 9 (26%) were due to direct bacterial inoculation through the skin, and in 4 cases, the mechanism of infection was unknown. Four out of these 34 cases occurred on prosthetic joints. Whereas hematogenous infections mostly occurred in immunocompromised hosts (17 of 21, 81%), direct inoculation was mostly seen in immunocompetent patients. Eighty-two percent of patients (28 out of 34) received trimethoprim-sulfamethoxazole-containing regimens and median antibiotic treatment duration was 24 weeks (range, 12–120) for hematogenous infections and 12 weeks (range, 6–24) for direct inoculations. Outcome was favorable in 27 cases despite unsystematic surgical management (17 cases) without sequelae in 70% of the cases. Nocardia arthritis is rare but its management is complex and should rely on a combined approach with rheumatologist, infectious diseases expert, and surgeon. PMID:26496274

    Numerous brands and types of artificial tears are available on the market for the treatment of dysfunctional tear syndrome. Past literature has focused on comparing the components of these products on patient’s clinical improvement. The wide array of products on the market presents challenges to both clinicians and patients when trying to choose between available tear replacement therapies. Different formulations affect patients based on etiology and severity of disease. In order to provide an unbiased comparison between available tear replacement therapies, we conducted a literature review of existing studies and National Institutes of Health clinical trials on commercially available, brand name artificial tears. Outcomes evaluated in each study, as well as the percent of patients showing clinical and symptomatic improvement, were analyzed. Fifty-one studies evaluating different brands of artificial tears, and their efficacy were identified. Out of the 51 studies, 18 were comparison studies testing brand name artificial tears directly against each other. Nearly all formulations of artificial tears provided significant benefit to patients with dysfunctional tear syndrome, but some proved superior to others. From the study data, a recommended treatment flowchart was derived. PMID:25114502

    Background To ensure patients and families receive appropriate end-of-life care pathways and guidelines aim to inform clinical decision making. Ensuring appropriate outcomes through the use of these decision aids is dependent on timely use. Diagnosing dying is a complex clinical decision, and most of the available practice checklists relate to cancer. There is a need to review evidence to establish diagnostic indicators that death is imminent on the basis of need rather than a cancer diagnosis. Aim To examine the evidence as to how patients are judged by clinicians as being in the final hours or days of life. Design Integrative literature review. Data sources Five electronic databases (2001–2011): Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, MEDLINE, EMBASE, PsycINFO and CINAHL. The search yielded a total of 576 hits, 331 titles and abstracts were screened, 42 papers were retrieved and reviewed and 23 articles were included. Results Analysis reveals an overarching theme of uncertainty in diagnosing dying and two subthemes: (1) ‘characteristics of dying’ involve dying trajectories that incorporate physical, social, spiritual and psychological decline towards death; (2) ‘treatment orientation’ where decision making related to diagnosing dying may remain focused towards biomedical interventions rather than systematic planning for end-of-life care. Conclusions The findings of this review support the explicit recognition of ‘uncertainty in diagnosing dying’ and the need to work with and within this concept. Clinical decision making needs to allow for recovery where that potential exists, but equally there is the need to avoid futile interventions. PMID:24780536

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

    SUMMARY Aim of the work Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. Materials and methods It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in English, in vitro studies, randomized clinical trial, reviews, meta-analysis, guide-lines. Were excluded from the search: descriptive studies, case reports, discussion articles, opinion’s leader. Results From studies results that common surface treatments (silanization, acid etching) are ineffective on zirconia because it has an inert surface without glassy component (on which this surface treatments act primarily), instead the sandblasting at 1atm with aluminium oxide (Al2O3) results significantly effective for the resulting roughening that increase the surface energy and the wettability of the material. Furthermore it has been shown that zinc phosphate-based cements, Bis-GMA-based and glass-ionomer cements can’t guarantee a stable long-term adhesion, instead resin cements containing phosphate monomer 10-methacryloyloxyidecyl-dihyidrogenphosphate (MDP) have shown higher adhesion and stability values than the other cements. In particular, it has seen that bond strength of zirconia copings on dentin, using MDP-based cement, is about 6,9MPa; this value is comparable to that obtained with gold copings cementation. Conclusions Analyzed studies have led to the following conclusions: sandblasting with aluminium oxide (Al2O3) is the best surface treatment to improve adhesion between resin cements and zirconia; resin cements containing phosphate ester monomers 10-methacryloyloxyidecyl-dihyidrogenphosphate (MDP) have shown in the studies an higher bond strength and stability after ageing treatment; the best procedure for cementing zirconia restorations results the combination of

    Objective Burnout is a state of mental and physical exhaustion related to work or care giving activities. Burnout during residency training has gained significant attention secondary to concerns regarding job performance and patient care. This article reviews the relevant literature on burnout in order to provide information to educators about its prevalence, features, impact, and potential interventions. Methods Studies were identified through a Medline and PsychInfo search from 1974 to 2009. Fifty-one studies were identified. Definition and description of burnout and measurement methods are presented followed by a thorough review of the studies. Results An examination of the burnout literature reveals that it is prevalent in medical students (28%–45%), residents (27%–75%, depending on specialty), as well as practicing physicians. Psychological distress and physical symptoms can impact work performance and patient safety. Distress during medical school can lead to burnout, which in turn can result in negative consequences as a working physician. Burnout also poses significant challenges during early training years in residency. Time demands, lack of control, work planning, work organization, inherently difficult job situations, and interpersonal relationships, are considered factors contributing to residents' burnout. Potential interventions include workplace-driven and individual-driven measures. Workplace interventions include education about burnout, workload modifications, increasing the diversity of work duties, stress management training, mentoring, emotional intelligence training, and wellness workshops. Individual-driven behavioral, social, and physical activities include promoting interpersonal professional relations, meditation, counseling, and exercise. Conclusions Educators need to develop an active awareness of burnout and ought to consider incorporating relevant instruction and interventions during the process of training resident physicians

    Gliomas are the most common primary brain tumor, the diagnosis of which is challenging. In this respect, the use of immunohistochemical proliferation markers may aid diagnosis; survivin, also known as Baculoviral IAP Repeat Containing 5, is one such marker. Survivin is a unique member of the inhibitors of apoptosis protein gene family, and is known for its dual function as an apoptosis inhibitor and mitosis regulator. Furthermore, survivin has been demonstrated to be overexpressed in a number of malignancies. The purpose of the present literature review was to gain an overview of studies published on the diagnostic and/or prognostic use of survivin in gliomas. Using PubMed, 19 studies matching the inclusion criteria were ultimately included in the present review. The majority of the studies identified revealed that survivin was significantly associated with other proliferation markers, histological malignancy grade, and inversely associated with prognosis. However, there were a number of inconsistencies between studies, which suggests a requirement for standardization of immunohistochemical procedures. PMID:27588117

    There is ongoing interest in including grey literature in systematic reviews. Including grey literature can broaden the scope to more relevant studies, thereby providing a more complete view of available evidence. Searching for grey literature can be challenging despite greater access through the Internet, search engines and online bibliographic databases. There are a number of publications that list sources for finding grey literature in systematic reviews. However, there is scant information about how searches for grey literature are executed and how it is included in the review process. This level of detail is important to ensure that reviews follow explicit methodology to be systematic, transparent and reproducible. The purpose of this paper is to provide a detailed account of one systematic review team's experience in searching for grey literature and including it throughout the review. We provide a brief overview of grey literature before describing our search and review approach. We also discuss the benefits and challenges of including grey literature in our systematic review, as well as the strengths and limitations to our approach. Detailed information about incorporating grey literature in reviews is important in advancing methodology as review teams adapt and build upon the approaches described.

    Djenkolism is an uncommon but important cause of acute kidney injury. It sporadically occurs after an ingestion of the djenkol bean (Archidendron pauciflorum), which is native to Southeast Asia. The clinical features defining djenkolism include: spasmodic suprapubic and/or flank pain; urinary obstruction; and acute kidney injury. The precise pathogenesis of acute kidney injury following djenkol ingestion remains unknown. However, it is proposed that an interaction between the characteristics of the ingested beans and the host factors causes hypersaturation of djenkolic acid crystals within the urinary system, resulting in subsequent obstructive nephropathy with sludge, stones, or possible spasms. We report a case of djenkolism from our rural clinic in Borneo, Indonesia. Our systematic literature review identified 96 reported cases of djenkolism. The majority of patients recovered with hydration, bicarbonate therapy, and pain medication. Three patients required surgical intervention; one patient required ureteral stenting for the obstructing djenkolic acid stones. Four of the 96 reported patients died from acute kidney failure. We stress the importance of awareness of djenkolism to guide medical practitioners in the treatment of this rare disease in resource-poor areas in Southeast Asia.

    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.

    Atherosclerosis is a multifactorial disease mainly caused by deposition of low-density lipoprotein (LD) cholesterol in macrophages of arterial walls. Atherosclerosis leads to heart attacks as well as stroke. Epidemiological studies showed that there is an inverse correlation between fruit and vegetable consumption and the risk of atherosclerosis. The promising effect of high vegetable and fruit containing diet on atherosclerosis is approved by several experimental studies on isolated phytochemicals such as flavonoids. Flavonoids are known to up-regulate endogenous antioxidant system, suppress oxidative and nitrosative stress, decrease macrophage oxidative stress through cellular oxygenase inhibition as well as interaction with several signal transduction pathways and from these ways, have therapeutic effects against atherosclerosis. Naringenin is a well known flavonoid belonging to the chemical class of flavanones. It is especially abundant in citrus fruits, especially grapefruits. A plethora of evidences ascribes to naringenin antiatherosclerotic effects. Naringenin abilities to decrease LDL and triglycerides as well as inhibit glucose uptake; increase high-density lipoprotein (HDL); co-oxidation of NADH; suppress protein oxidation; protect against intercellular adhesion molecule-1(ICAM-1); suppress macrophage inflammation; inhibit leukotriene B4, monocyte adhesion and foam cell formation; induce of HO-1 and G 0/G 1 cell cycle arrest in vascular smooth muscle cells (VSMC) and down regulate atherosclerosis related genes are believed to have crucial role in the promising role against atherosclerosis. In the present review, we have summarized the available literature data on the anti-atherosclerotic effects of naringenin and its possible mechanisms of action.

    Despite recent findings on the treatment of schizophrenia, it is an illness still associated with high morbidity and incapacity in social and work domains. There is a growing interest in examining the phases prior to the development of the illness so as to make early interventions that would potentially change its devastating course. The attenuated psychosis syndrome was included in the section III of the last version of the Diagnostic and Statistical Manual of Mental Disorders as a condition in which a patient exhibits mild psychotic symptoms, an intact reality testing and certain degree of social or occupational impairment. The present work is a review of the available literature on this subject. The main findings were: the risk of conversion to a psychotic disorder is relatively low and there are some variables (social withdrawal, negative symptoms, neurocognitive impairment, poor global functioning and certain neuroimaging findings) that increase this risk. Those people diagnosed with attenuated psychosis syndrome had one or more other current psychiatric comorbid conditions and these are the main reason to warrant medical attention. Regarding to the treatment of this condition, there are available evidence on atypical antipsychotics, cognitive-behavioral therapy and omega 3 fatty acid. PMID:26650554

    With the amazing increasing in number of participants, rock climbing has become a popular sport in the last decade. A growing number of participants, with different skill level, inevitably leads to an increased number of injuries related to this practice. The kind of lesions that can be observed in rock-climbers is very specific and often involves the hand. For this reason is very important for any hand surgeon that is exposed to sport injuries to know which and the most common injuries related to this sport and which are the basic principles for the treatment of those. The aim of this article is to review the literature that has been published in the last ten year in this topic. On the NCBI database 22 articles where found that where related to rock climbing lesion affecting the hand or the whole body. Differences where found according to kind of rock climbing activity that was analyzed, alpine climb leads to more serious injuries, often affecting the lower limb, while in sport and recreational rock climbing the upper limb and the hand are definitely the most affected parts. Flexor pulley lesions, followed by fractures and strains are the most common lesions affecting the hand that are related to this practice.

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

    The concept of vulnerability is delimited by dynamic social and multigenerational processes involving at least three dimensions: exposure to risk trajectories, internal and external capabilities of reaction and possibilities of adaptation based on both the intensity of risk and the resilience of people. In order to identify and describe the synthetic indices of vulnerability, there was an integrative literature review. We consulted free access articles indexed in the following databases: BioMed, Bireme, PubMed, Reldalyc, SciELO and Web of Science; and we used controlled descriptors in English and Portuguese for all time slots available with selection and analysis of 47 studies that reported results of 23 synthetic indices of vulnerability. The results showed that the synthetic indices of vulnerability address four themes: social determinants of health; environmental and climatic conditions; family and course of life; territories and specific geographic areas. It was concluded that the definition of the components and indicators, as well as the methodologies adopted for the construction of synthetic indices need to be evaluated by means of the limitations and advantages of reporting the vulnerability through summary measures in policy formulation and decision-making aimed at human development.

    2016-08-01

    The objective of this first literature review, in this area, is to unveil the current status of knowledge on superstition in sport. Its outcome reveals that superstitious behaviors vary with the type of sport, athletic level, as well as athletic role. In agreement with past theories, they increase with the level of challenge, as reflected by the importance of the competition, as well as with the level of uncertainty. Cultural factors, in conjunction with the education level, as well as gender, have a strong influence on superstitious behaviors in sports. Based on current thoughts, religiosity and superstition are different psychological constructs used as psychological aids by several athletes. Personality factors appear to mediate the manifestation of the behavior. Elite athletes are clearly more superstitious than non-elite athletes, An interaction between athletic skill and task-difficulty emerges to be another strong predictor of superstition in sport. It is evident that a set of complex personal and situational factors interact in the manifestation of superstitious behavior in sport that is used for the regulation of emotions in a quest for optimal performance. It is concluded that the objective benefits (i.e., success) of superstition in sport may be ascribed to the placebo effect that yields an increased sense of control and mental reassurance in unpredictable contest situations.

    The purpose of this article is to review the nursing literature related to professional boundary violations in nursing. A search was conducted using CINAHL, MEDLINE, Ebscohost, and NCSBN. The key words searched were professional boundaries, boundary violation, boundary crossings, nurse, home health nurses, and home nursing. The search returned over 40 publications related specifically to boundary violations and nursing although only four of them are published research studies and one as a dissertation. Seven common characteristics emerged from the nonresearch nursing articles on professional boundaries: (1) Dual relations/role reversal, (2) Gifts and money, (3) Excessive self-disclosure, (4) Secretive behavior, (5) Excessive attention/overinvolvement, (6) Sexual behavior, and (7) Social media. Additional nursing research is greatly needed in the area of professional boundaries. The nurse-patient relationship should always be maintained for the benefit of the patient and not the personal gain of the nurse. Ongoing education in nursing practice regarding professional boundaries is needed. Nurses need to be mindful of state practice acts, codes of conduct, and employer policies. PMID:26034824

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

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

  1. Microalgae harvesting and processing: a literature review

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

    1984-08-01

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

    A new solvent system is being evaluated for use in the Modular Caustic-Side Solvent Extraction Unit (MCU) and in the Salt Waste Processing Facility (SWPF). The new system replaces the current dilute nitric acid strip solution with 0.01 M boric acid. This literature study is performed to determine if there is a potential for boric acid to crystallize in the lines with emphasis on the transfer lines to the Defense Waste Processing Facility. This report focuses on the aqueous phase chemistry of boric acid under conditions relevant to MCU and SWPF. Operating and transfer conditions examined for the purpose of this review include temperatures between 13 C (McLeskey, 2008) and 45 C (Fondeur, 2007) and concentrations from 0 to 3M in nitric acid as well as exposure of small amounts of entrained boric acid in the organic phase to the sodium hydroxide caustic wash stream. Experiments were also conducted to observe any chemical reactions and off-gas generation that could occur when 0.01 M boric acid solution mixes with 3 M nitric acid solution and vice versa. Based on the low concentration (0.01M) of boric acid in the MCU/SWPF strip acid and the moderate operating temperatures (13 C to 45 C), it is unlikely that crystallization of boric acid will occur in the acid strip solution under process or transfer conditions. Mixing experiments of boric and nitric acid show no measurable gas generation (< 1 cc of gas per liter of solution) under similar process conditions.

    2015-07-01

    Use of restraint chairs by law enforcement for violent individuals has generated controversy and a source of litigation because of reported injuries and deaths of restrained subjects. The purpose of this study is to review the available medical and legal literature and to allow the development of evidence-based, best practice recommendations to inform the further development of restraint chair policies. This is a structured literature review of four databases, two medical and two legal. The medical review focus was on the restraint chair with additional review of materials regarding other restraint methods and options. The legal review focused on litigation cases involving the restraint chair. The review of the medical literature revealed 21 peer-reviewed studies investigating the physiological or psychological effects of using a restraint chair on humans or primates. Of these studies, 20 were performed on primates. The single human study revealed no clinically significant effects from the restraint chair on test subjects. The legal literature review revealed very few cases where the restraint chair was either a major or minor focus. The overall issues relating to the restraint chair cases involved deviations from set protocols and rarely involved issues with the chair itself. The available medical literature reveals that the restraint chair poses little to no medical risk. Additionally, when used appropriately, the restraint chair alone carries little legal liability. With proper monitoring and adherence to set protocols, the restraint chair is a safe and appropriate device for use in restraining violent individuals.

    2007-07-01

    The most commonly used measurement of coal grindability is the Hardgrove Grindability Index (HGI) however, many solid fuels do not exhibit the grinding performance predicted by this index. Parameters which can influence grindability and possibly lead to inaccurate prediction of grindability as determined by HGI include: composition and texture, mineral components, brittleness, and rank (which establishes carbon, volatile matter, and moisture contents). Descriptions of these parameters are provided. Alternative measurements of grindability from literature are presented. The most promising may be a revision on the standard HGI, in which a mill capacity factor is derived from the number of mill rotations to crush coal to a specific fineness. 88 refs.

    Kanewala, Upulee; Bieman, James M.

    2014-01-01

    Context Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. Objective This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. Method We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. Results We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Conclusions Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques. PMID:25125798

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

    2013-01-01

    The term cosmetic has a broad definition and includes personal care products, hair care products, nail care products, and sunscreens. Modern cosmetics are safe for most users, and adverse reactions are very rare because the manufacturers invest heavily in safety, quality control, and product testing before releasing the product to the market. Despite these efforts, adverse reactions occur. Skin care products are major contributors to cosmetic allergic contact dermatitis (ACD), followed by hair care and nail care products. The most common allergens are fragrances and preservatives. The diagnosis of cosmetic allergy is established by reviewing the patient's clinical history and physical examination findings and confirmed with skin patch testing. Patch testing is the standard method for detecting allergens responsible for eliciting ACD. The purpose of this article was to review the prevalence, legislative laws, and role of patch testing in ACD.

    The basidiomycosis, fungal infections provoked by basidiomycetes or agaric fungi have been recorded at growing frequencies in the medical literature, especially after the advent of AIDS in 1991. The basidiospores of these fungi, scattered in the atmosphere and transported by winds or air currents, reach the maxillary sinuses through the nasal route, most of the times causing signs and symptoms of chronic sinusitis. Basidiomycetes have also been isolated from sputum, especially Schizophyllum commune. Lesions of the buccal mucosa, brain abscesses, onychomycosis and endocarditis have been described, with a growing interest in this type of deep mycosis on the part of mycologists and infectologists. The present paper reports descriptions of mycetism as well as infectious processes caused by basidiomycetes, such as Schizophyllum commune, Ustilago maydis (= Ustilago zeae) and Coprinus cinereus.

    2014-01-01

    Lipomas are the most common type of soft tissue mesenchymal tumors. They are typically located subcutaneously and consist of mature fatty tissue. When they occur under the enclosing fascia, they are called deep-seated lipomas. Infrequently, lipomas can arise inside the muscle and are called intramuscular lipomas. Intramuscular lipomas have been commonly investigated and categorized in the same group as other deep-seated and superficial lipomatous lesions. Their clinical, histological and imaging characteristics may resemble well-differentiated liposarcomas, further adding to the difficulties in the differential diagnosis. This article summarizes the available literature and describes the typical epidemiological, pathological and clinical features of intramuscular lipomas, as well as delineating their treatment and prognosis.

Results Our search strategy identified 488 papers. A comparison between the papers published between 2001–6 and 2007–12 showed an increase in every SNOMED CT focus category. The number of papers classified as ‘theoretical’ increased from 46 to 78, ‘pre-development/design’ increased from 61 to 173 and ‘implementation’ increased from 10 to 34. Papers classified as ‘evaluation/commodity’ only started to appear from 2010. Conclusions The majority of studies focused on ‘theoretical’ and ‘pre-development/design’. This is still encouraging as SNOMED CT is being harmonized with other standardized terminologies and is being evaluated to determine the content coverage of local terms, which is usually one of the first steps towards adoption. Most implementations are not published in the scientific literature, requiring a look beyond the scientific literature to gain insights into SNOMED CT implementations. PMID:23828173

    An effective and long-term treatment of cellulite has not been well established. To our knowledge, no review has analyzed the whole range of treatments for this condition. We conducted a review of in vivo studies on humans adopting the key words "cellulite" and "treatment." The studies were included according to eligibility criteria. We performed an analysis to estimate the overall effect of cellulite treatments from clinical studies. Medline library was screened up to December 2014 to identify eligible studies. We included 73 original studies in the present review. All of them were clinical studies, in most of them, only women were recruited. Above the studies searched up, 66 tested the effectiveness of an exclusive treatment performed without the association to other procedures: 11 topical agents, 10 shock-wave therapy, 10 radio frequency, eight laser therapy, five oral therapy, four manual massage therapy, three carbon dioxide therapy, two compressive therapy, two infrared therapy, one dermabrasion, and 11 devices that use an association of multiple treatments. Seven papers tested a combination of two or more treatments. The mean difference of clinical morphologic features and ultrastructural changes between the treated group and the controlled showed significant heterogeneity between studies. It is still difficult to indicate an exclusive and effective single treatment for this condition. Our analysis purposed to obtain a complete overview of the available treatments in cellulite reduction.

    2013-10-01

    A comprehensive review of the literature of the universal experience of living on the edge is discussed. Literature was reviewed from biology, criminology, ecology, economics, ethics, finance, fine arts, historical biography, medicine, nursing, philosophy, physiology, psychology, sociology, and theology. Three themes emerged with this literature review: living on the edge as a sacred place one travels to or where one lives, living on the edge as a choice in taking risks and surviving danger, and living on the edge as engaging with health experiences in which persons and nurses coparticipate. Living on the edge is a visionary quest into a new frontier that holds illimitable possibilities that transform the world. The literature is discussed according to theoretical and research findings.

    2015-01-01

    Background and Aims Compulsive sexual behavior (CSB) is a common disorder featuring repetitive, intrusive and distressing sexual thoughts, urges and behaviors that negatively affect many aspects of an individual’s life. This article reviews the clinical characteristics of CSB, cognitive aspects of the behaviors, and treatment options. Methods We reviewed the literature regarding the clinical aspects of CSB and treatment approaches. Results The literature review of the clinical aspects of CSB demonstrates that there is likely a substantial heterogeneity within the disorder. In addition, the treatment literature lacks sufficient evidence-based approaches to develop a clear treatment algorithm. Conclusions Although discussed in the psychological literature for years, CSB continues to defy easy categorization within mental health. Further research needs to be completed to understand where CSB falls within the psychiatric nosology. PMID:26014671

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

    Graeme, Kimberlie A

    2014-06-01

    Approximately 100 of the known species of mushrooms are poisonous to humans. New toxic mushroom species continue to be identified. Some species initially classified as edible are later reclassified as toxic. This results in a continually expanding list of toxic mushrooms. As new toxic species are identified, some classic teachings about mycetism no longer hold true. As more toxic mushrooms are identified and more toxic syndromes are reported, older classification systems fail to effectively accommodate mycetism. This review provides an update of myscetism and classifies mushroom poisonings by the primary organ system affected, permitting expansion, as new, toxic mushroom species are discovered.

    Metal phosphides in general and aluminium phosphide in particular are potent insecticides and rodenticides. These are commercially used for protection of crops during storage, as well as during transportation. However, these are highly toxic substances. Their detrimental effects may range from nausea and headache to renal failure and death. It is, therefore, pertinent to ensure their circumspect handling to avoid poisoning episodes. Its poisoning has a high mortality and recent years have seen an increase in the number of poisoning cases and deaths caused by suicidal ingestion. Yet due to their broad spectrum applications, these chemicals cannot be written off. The present communication reviews the various aspects of toxicity associated with metal phosphides.

    Objectives The aim of this review was to assess the current evidence regarding the efficacy of teaching skills programs for junior medical officers.  We aimed to compare and contrast these results with findings from previous literature reviews, the last of which were published in 2009. Methods In order to capture studies since the last published literature reviews, five databases and grey literature were searched for publications from January 2008 to January 2015. A search for literature reviews without using the timeframe limitation was also performed. Results The search from January 2008 to January 2015 resulted in the inclusion of 12 studies. Five systematic reviews of the topic were found which included 39 individual studies that were also analysed. Nearly all studies reported positive effects. Twenty nine studies reported change in attitudes, 28 reported modification in knowledge, 28 reported change in behaviour, 6 reported change in the organisation and two reported change in program participant’s students. There were substantial threats of bias present. Conclusions The literature reviewed demonstrated many positive effects of teaching skills programs, which supports their utilization. However, high level outcomes need to be evaluated over longer periods of time to establish their true impact. An organisation specific approach to these programs needs to occur using sound course design principles, and they need to be reported in evaluation trials that are designed with robust methodology.

    The excessive production of reactive oxygen species in nervous tissues is considered one of the major risk factors of neurodegenerative diseases. During the last two decades, much attention has been paid to the antioxidant and anti-inflammatory activity of natural products and compounds isolated from natural products which are often characterized by high efficacy and low adverse effects. Berberine is an isoquinoline alkaloid, widely present in different medicinal herbs, especially in the genus Berberis. It is mainly used as antidiarrhoeal, antibacterial, antifungal, and antiprotozoal agent. However, current research has focused on its beneficial role in neurodegenerative diseases, mainly due to its powerful antioxidant effect. The therapeutic potential of Berberine in different neurodegenerative diseases such as Alzheimer, Parkinson and Huntington disease has been brought to evidence by numerous studies. However, a limited number of reviews focus on the beneficial role of Berberine against neurodegeneration. The main objective of this review is to discuss the role of oxidative stress in neurodegeneration and the potential role of antioxidant compounds, in particular Berberine which is analyzed in its chemical structure, source, bioavailability, therapeutic potential, with special attention to its mechanism of action at a molecular level.

    1996-09-01

    Homesickness has not received due attention from psychological researchers, in spite of the fact that it is of considerable interest to counsellors and care-givers of those who have migrated or moved temporarily or permanently (e.g. immigrants, refugees, students, soldiers). First, this review addresses the definition of homesickness, the possible different kinds of homesickness, its prevalence rate, and symptomatology, Secondly, an overview is given of the theories that account for psychological distress following leaving home. These theories link homesickness with separation-anxiety and loss, the interruption of lifestyle, reduced control, role change, and internal conflict. In addition, the review focuses on: (i) studies that show that subjects reporting homesickness differ from non-homesick persons in terms of personality; (ii) the analyses of environmental characteristics that may play a crucial role in the onset and course of homesickness. Thirdly, Fisher's (1989) composite model of homesickness, which summarizes key findings of the major studies on homesickness is discussed. Fourthly, methodological issues are addressed. Finally, suggestions for future research are presented and possibilities for interventions are proposed.

    2012-02-01

    Back lumbar hernia is a rare abdominal wall defect that usually presents spontaneously after trauma or lumbar surgery or, less frequently, during infancy (congenital). Few reports have been published in the literature describing primary lumbar hernia. A general surgeon will have the opportunity to repair only one or a few lumbar hernia cases in his/her lifetime. We report a case of a healthy 50-year-old man, with no previous surgeries or history of trauma, who presented to the outpatient department with abdominal discomfort, pain, and a sensation of a growing mass on his lower left back for 4 years. CT scan of the abdomen showed a mass in the left posterolateral abdominal wall. Specifically, a herniation of retroperitoneal fat between the erector spinae muscle group and internal oblique muscles through aponeurosis of the transversalis muscle (Grynfeltt hernia). The patient underwent a small lumbotomy, polypropylene mesh was placed and he recovered well. Although many techniques have been described for the surgical management of such hernias, none of them can be recommended as the preferred method. Our impression, however, is that the open approach, with a small lumbotomy, seems to be easy, safe and presents good postoperative recovery.

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

    PubMed

    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.

  18. Irradiation preservation of seafood: Literature review

    SciTech Connect

    Molton, P.M.

    1987-10-01

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

    Nitzan, Dorrit; González-Garcia, Raul

    2012-01-01

    The treatment of the temporomandibular joint (TMJ) is still controversial. TMJ arthrocentesis represents a form of minimally invasive surgical treatment in patients suffering from internal derangement of the TMJ, especially closed lock. It consists of washing the joint with the possibility of depositing a drug or other therapeutic substance. Resolution of symptoms is due to the removal of chemical inflammatory mediators and changes in intra-articular pressure. Numerous clinical studies regarding this technique have been published. The goal of this paper is to review all clinical articles that have been published with regard to the critique of this technique. 19 articles with different designs fulfilling selection guidelines were chosen. A series of clinical and procedure variables were analyzed. Although the mean of improvement was higher that 80%, further research is needed to determine more homogeneous indications for TMJ athrocentesis. Key words:Temporomandibular joint, arthrocentesis, minimally invasive surgery. PMID:22322493

    2007-01-01

    Context The perinatal period is one during which health care services are in high demand. Like other health care sub-sectors, perinatal health care delivery has undergone significant changes in recent years, such as the integrative wave that has swept through the health care industry since the early 1990s. Purpose The present study aims at reviewing scholarly work on integrated perinatal care to provide support for policy decision-making. Results Researchers interested in integrated perinatal care have, by assessing the effectiveness of individual clinical practices and intervention programs, mainly addressed issues of continuity of care and clinical and professional integration. Conclusions Improvements in perinatal health care delivery appear related not to structurally integrated health care delivery systems, but to organizing modalities that aim to support woman-centred care and cooperative clinical practice.

    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. PMID:27545009

    PubMed

    Ancker, Jessica S; Kaufman, David

    2007-01-01

    The purpose of this review is to organize various published conceptions of health numeracy and to discuss how health numeracy contributes to the productive use of quantitative information for health. We define health numeracy as the individual-level skills needed to understand and use quantitative health information, including basic computation skills, ability to use information in documents and non-text formats such as graphs, and ability to communicate orally. We also identify two other factors affecting whether a consumer can use quantitative health information: design of documents and other information artifacts, and health-care providers' communication skills. We draw upon the distributed cognition perspective to argue that essential ingredients for the productive use of quantitative health information include not only health numeracy but also good provider communication skills, as well as documents and devices that are designed to enhance comprehension and cognition.

OBJECTIVE To review the ecology, virology, epidemiology, clinical characteristics, diagnosis, prevention, and control of West Nile virus, with an emphasis on North America. EVIDENCE REVIEW PubMed electronic database was searched through February 5, 2013. United States national surveillance data were gathered from the Centers for Disease Control and Prevention. FINDINGS West Nile virus is now endemic throughout the contiguous United States, with 16 196 human neuroinvasive disease cases and 1549 deaths reported since 1999. More than 780 000 illnesses have likely occurred. To date, incidence is highest in the Midwest from mid-July to early September. West Nile fever develops in approximately 25% of those infected, varies greatly in clinical severity, and symptoms may be prolonged. Neuroinvasive disease (meningitis, encephalitis, acute flaccid paralysis) develops in less than 1% but carries a fatality rate of approximately 10%. Encephalitis has a highly variable clinical course but often is associated with considerable long-term morbidity. Approximately two-thirds of those with paralysis remain with significant weakness in affected limbs. Diagnosis usually rests on detection of IgM antibody in serum or cerebrospinal fluid. Treatment is supportive; no licensed human vaccine exists. Prevention uses an integrated pest management approach, which focuses on surveillance, elimination of mosquito breeding sites, and larval and adult mosquito management using pesticides to keep mosquito populations low. During outbreaks or impending outbreaks, emphasis shifts to aggressive adult mosquito control to reduce the abundance of infected, biting mosquitoes. Pesticide exposure and adverse human health events following adult mosquito control operations for West Nile virus appear negligible. CONCLUSIONS AND

  5. [Beauty judgment: review of the literature].

    PubMed

    2014-03-01

    Esthetic judgments are surely subjective, but as surely, that does not preclude them being studied objectively through rigorous scientific methods. The factual basis of a science of esthetics is not to settle whether some person or image is "objectively beautiful" but rather to determine whether some representative set or sets of individuals judge or experience him/her/it as beautiful or unattractive. The aim of this paper is to review the definitional, theoretical and methodological aspects pertaining to the perception of facial/dental attractiveness by a group of representative individuals. The first part lays down the basic principles of the perception of facial/dental attractiveness: the perception involves a jury, a field of investigation and a test providing quantitative data; the following general determinants of beauty perception are reviewed: the average morphology, the judge's cultural background, the numerology, the judge's ethnical origin. Indirect determinants are the dentition, the osseous architecture and the muscular envelope. Some disruptive factors might alter the judges' facial perception. They might be qualified as either peripheral to the face or psycho-social factors. Peripheral factors include hair style and color, skin hue, wrinkles, lips color... Psycho-social factors cover the personality of the subject being evaluated, his/her intelligence or behavior. The second part deals specifically with the methodology used to determine facial attractiveness and to correlate this latter with a specific morphology. Typically such a study aims to determine average esthetic preferences for some set of visual displays among a particular jury, given a specific task to judge esthetic quality or qualities. The sample being studied, the displays, the jury or jurys, the rating procedure must all be specified prior to collecting data. A specific emphasis will be given to the rating process and the associated morphometrics, the ultimate goal being to

  7. Sickness at high altitude: a literature review.

    PubMed

    Brundrett, G

    2002-03-01

    When some individuals spend just a few hours at low atmospheric pressure above 1,500 m (5,000 ft)--such as when climbing a mountain or flying in a plane at high altitude--they become ill. Altitude sickness studies originally concentrated on life-threatening illnesses which beset determined and athletic climbers at extreme altitudes. In recent years, however, research attention is moving towards milder forms of sickness reported by a significant proportion of the growing number of visitors to mountain and ski resorts at more moderate altitude. Some of this research is also relevant in understanding the problems experienced by passengers in newer planes that fly at a significantly higher equivalent cabin altitude, i.e. 2,440 m (8,000 ft), than earlier designs. Engineering solutions--such as enriched oxygen in enclosed spaces at altitude, or in the case of aircraft, lower cabin altitudes--are possible, but for an economic assessment to be realistic an engineer needs to identify the scale of the problem and to understand the factors determining susceptibility. This review concentrates on the problems of mountain sickness in the ordinary population at altitudes of around 3,000 m (10,000 ft); this is a problem of growing concern as ski resorts develop, mountain trekking increases in popularity, and as higher altitude cabin pressures are achieved in aircraft.

  8. Complex ankle arthrodesis: Review of the literature

    PubMed Central

    2015-01-01

    Complex ankle arthrodesis is defined as an ankle fusion that is at high risk of delayed and nonunion secondary to patient comorbidities and/or local ankle/hindfoot factors. Risk factors that contribute to defining this group of patients can be divided into systemic factors and local factors pertaining to co-existing ankle or hindfoot pathology. Orthopaedic surgeons should be aware of these risk factors and their association with patients’ outcomes after complex ankle fusions. Both external and internal fixations have demonstrated positive outcomes with regards to achieving stable fixation and minimizing infection. Recent innovations in the application of biophysical agents and devices have shown promising results as adjuncts for healing. Both osteoconductive and osteoinductive agents have been effectively utilized as biological adjuncts for bone healing with low complication rates. Devices such as pulsed electromagnetic field bone stimulators, internal direct current stimulators and low-intensity pulsed ultrasound bone stimulators have been associated with faster bone healing and improved outcomes scores when compared with controls. The aim of this review article is to present a comprehensive approach to the management of complex ankle fusions, including the use of biophysical adjuncts for healing and a proposed algorithm for their treatment.

    Human toxocariasis (HT) is a zoonotic disease caused by infection with the larval stage of Toxocara canis, the intestinal roundworm of dogs. Infection can be associated with a wide clinical spectrum varying from asymptomatic to severe organ injury. While the incidence of symptomatic human toxocariasis appears to be low, infection of the human population is widespread. In Cuba, a clear overview on the status of the disease is lacking. Here, we review the available information on toxocariasis in Cuba as a first step to estimate the importance of the disease in the country. Findings are discussed and put in a broader perspective. Data gaps are identified and suggestions on how to address these are presented. The available country data suggest that Toxocara infection of the definitive dog host and environmental contamination with Toxocara spp. eggs is substantial, but information on HT is less conclusive. The availability of adequate diagnostic tools in the country should be guaranteed. Dedicated studies are needed for a reliable assessment of the impact of toxocariasis in Cuba and the design of prevention or control strategies. PMID:22389726

    Fingerprints have a key role in criminal investigations and are the most commonly used form of evidence worldwide. Significant gaps remain however, in the understanding of fingerprint chemistry, including enhancement reaction mechanisms and the effect of environmental variables and time on composition. Determining the age of a fingerprint is also a relatively unexplored area. A successful method, with reliable and quantitative estimates, would have numerous advantages. Previous unreliable methods have predominantly focused on enhancement success based on physical and chemical changes. This review explores variations in composition due to donor characteristics and environmental variables, and identifies gaps for further research. We also present a qualitative and quantitative summary of the effect of time on composition. Kinetics are presented where known, with summary schematics for reaction mechanisms. Previous studies exploring methods for determining the age of a fingerprint are also discussed, including their advantages and disadvantages. Lastly we propose a potentially more accurate and reliable methodology for determining fingerprint age based on quantitative kinetic changes to the composition of a fingerprint over time.

    2014-09-01

    The Government of Ghana has taken important steps to mitigate the impact of unsafe abortion. However, the expected decline in maternal deaths is yet to be realized. This literature review aims to present findings from empirical research directly related to abortion provision in Ghana and identify gaps for future research. A total of four (4) databases were searched with the keywords "Ghana and abortion" and hand review of reference lists was conducted. All abstracts were reviewed. The final include sample was 39 articles. Abortion-related complications represent a large component of admissions to gynecological wards in hospitals in Ghana as well as a large contributor to maternal mortality. Almost half of the included studies were hospital-based, mainly chart reviews. This review has identified gaps in the literature including: interviewing women who have sought unsafe abortions and with healthcare providers who may act as gatekeepers to women wishing to access safe abortion services.

    Objective The present study was aimed at reviewing the literature to identify solutions for problems observed in radiology services. Materials and Methods Basic, qualitative, exploratory literature review at Scopus and SciELO databases, utilizing the Mendeley and Illustrator CC Adobe softwares. Results In the databases, 565 papers – 120 out of them, pdf free – were identified. Problems observed in the radiology sector are related to procedures scheduling, humanization, lack of training, poor knowledge and use of management techniques, and interaction with users. The design management provides the services with interesting solutions such as Benchmarking, CRM, Lean Approach, ServiceBlueprinting, continued education, among others. Conclusion Literature review is an important tool to identify problems and respective solutions. However, considering the small number of studies approaching management of radiology services, this is a great field of research for the development of deeper studies. PMID:26543281

  15. Safety signal detection: the relevance of literature review.

    Pontes, Helena; Clément, Mallorie; Rollason, Victoria

    2014-07-01

    Adverse drug reactions (ADRs) represent an important risk for patients and have a significant economic impact on health systems. ADRs are the fifth most common cause of hospital death, with a burden estimated at 197,000 deaths per year in the EU. This has a societal cost of 79 billion per year. Because of this strong impact in public health, regulatory authorities (RAs) worldwide are implementing new pharmacovigilance legislation to promote and protect public health by reducing the burden of ADRs through the detection of safety signals. Although, traditionally, signal detection activities have mainly been performed based on spontaneous reporting from healthcare professionals and national health RAs, the new pharmacovigilance legislation underlines the relevance of other sources of information (such as scientific literature) for the evaluation of the benefit-risk balance of a certain product. This review aims to highlight the relevance of periodic scientific literature screening in the safety signal detection process. The authors present four practical examples where a safety signal that was detected from a literature report had an impact on the lifecycle of a drug. In addition, based on practical experience of the screening of medical and scientific literature for safety purposes, this article analyses the requirements of the new pharmacovigilance guidelines on literature screening and highlights the need for the implementation of a literature review procedure and the main challenges encountered when performing literature screening for safety aspects.

    2004-12-01

    The functional demands of patients are highly variable and individual, requiring dental treatment to be tailored to the individual's needs and adaptive capability. The World Health Organization indicates that a functional, esthetic, natural dentition has at least 20 teeth, while the literature indicates that dental arches comprising the anterior and premolar regions meet the requirements of a functional dentition. The English-language peer-reviewed literature pertaining to the short dental arch (SDA) was identified through the Medline search engine covering the period between 1966 and the present and critically reviewed. This treatment option for the partially dentate patient may provide oral functionality, improved oral hygiene, comfort, and, possibly, reduced costs.

    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.

  20. Clinical librarianship: a systematic review of the literature.

    2003-06-01

    Clinical librarianship (CL), currently receiving renewed interest world-wide, seeks to provide quality-filtered information to health professionals at the point of need to support clinical decision-making. This review builds upon the work of Cimpl (Bulletin of the Medical Library Association 1985, 73, 21-8) and attempts to establish the evidence base for CL. The objectives were to determine, from the literature, whether CL services are used by clinicians, have an effect on patient care, and/or clinicians' use of literature in practice and/or are cost-effective. The methodology used was a systematic review of the literature, following, where possible, the NHS Centre for Reviews and Dissemination (CRD) framework. Modifications to this methodology included the resources searched, and the critical appraisal checklist (CriSTAL) used. Two hundred and eighty-four unique references were retrieved. Seventeen (16 unique) evaluative and a further 33 descriptive studies met the inclusion criteria. The quality of reporting of the literature was generally poor. CL programmes appear to be well-used and received by clinicians. However, there is insufficient evidence available on their effect on patient care, clinicians' use of literature in practice, and their cost-effectiveness, thus highlighting the need for further high-quality research.

    PubMed Central

    Kaplan, Nathan B.; Molinari, Christine; Molinari, Robert W.

    2015-01-01

    Study Design Literature review and case report. Objective Review the existing literature and report the successful nonoperative management of a two-level craniocervical ligamentous distraction injury. Methods A PubMed and Medline review revealed only three limited reports involving the nonoperative management of patients with craniocervical distraction injury. This article reviews the existing literature and reports the case of a 27-year-old man who was involved in a motorcycle accident and sustained multiple systemic injuries and ligamentous distraction injuries to both occipitocervical joints and both C1–C2 joints. The patient's traumatic brain injury and bilateral pulmonary contusions precluded safe operative management of the two-level craniocervical distraction injury. Therefore, the patient was placed in a halo immobilization device. Results The literature remains unclear as to the specific indications for nonoperative management of ligamentous craniocervical injuries. Nonoperative management was associated with poor outcomes in the majority of reported patients. We report a patient who was managed for 6 months in a halo device. Posttreatment computed tomography and flexion–extension radiographs demonstrated stable occipitocervical and C1–C2 joints bilaterally. The patient reported minimal neck pain and had excellent functional outcome with a Neck Disability Index score of 2 points at 41 months postoperatively. He returned to preinjury level of employment without restriction. Conclusions Further study is needed to determine which craniocervical injuries may be managed successfully with nonoperative measures. PMID:26682101

  15. Role modeling in undergraduate nursing education: an integrative literature review.

    PubMed

    Baldwin, Adele; Mills, Jane; Birks, Melanie; Budden, Lea

    2014-06-01

    The transition of nursing education from the hospital setting to the university sector over recent decades has opened dialog about who is guiding the development of nursing students' professional identity. In addition, there is ongoing debate over real or perceived gaps between nursing student learning in the university and the clinical area, how this translates into professional behaviors and how well students make the transition between the two settings. This paper presents the findings of an integrative literature review into the topic of role modeling in undergraduate nursing education. This review was conducted to identify and appraise research findings about role modeling of professional behaviors for undergraduate nursing students. Literature reviewed from 2000 onwards assesses what is currently known about role modeling of undergraduate nursing students. A systematic search of the databases of CINAHL, Scopus and PubMed from 2000 onwards resulted in the selection of 33 articles for deeper analysis. Two clear themes emerged from the literature, the first relating to nurse clinicians as role models for students during clinical placements and the second relating to nurse academics as role models in the academic setting. Findings from this integrative literature review show an imbalance in the recognition of the role modeling of professional behaviors in the clinical versus the academic setting. Nurses in academic settings have more contact with the students over their period of study and as such, the significance of nurse academics as student role models requires further investigation.

    2015-01-01

    Abstract Intravascular myopericytoma (IVMP), regarded as a variant of myopericytoma, is a rare tumor. Very few cases have been described, none in the foot. The first case of IVMP located in the heel of the foot is described in this article. A literature review is reported of all cases of IVMP published in the English literature. A 48-year-old man possessed an IVMP on the heel of the right foot. The physical examination and histopathological and ultrasound studies are described. The literature review yielded 5 cases of IVMP, 2 of which were in the thigh and 1 each in the oral mucosa, the periorbital region, and the leg. The possibility that these lesions may be malignant suggests that the histopathological study of vascular tumors should include immunohistochemical tests. PMID:25789958

  20. Use of prebriefing in nursing simulation: a literature review.

    PubMed

    Page-Cutrara, Karin

    2014-03-01

    Simulation has gained much attention in the literature for its contributions to nursing education; however, the simulation process itself and how each of the components-prebriefing, scenario, and debriefing-are effective for learning are understudied. Specifically, how prebriefing may enrich simulation for learners without adequate prior clinical experience or how it may develop complex thinking skills and clinical judgment is not well understood. This article comprehensively reviews the available nursing simulation literature about the phenomenon of prebriefing and critically evaluates its current role as a component of nursing simulation. Gaps in the reviewed literature regarding the definition and purpose of prebriefing, alternate learning structures used in prebriefing, and use in relation to learner outcomes were identified. Implications for undergraduate nursing education and recommendations for further research are discussed.

  1. Curriculum reform in baccalaureate nursing education: review of the literature.

    PubMed

    Forbes, Maryann O; Hickey, Mary T

    2009-01-01

    The debate surrounding the need for reform in nursing education has been heard for well over a decade. Recently, deficiencies in the quality of patient care, as well as patient safety issues, have led to calls for change in health professions education by nursing organizations and the Institute of Medicine (IOM). The rationale and scope of any proposed curricular revision or changes in teaching practices must be firmly grounded in a comprehensive review of the literature and based on current research findings. This article synthesizes the recent literature related to curriculum reform and innovation in nursing education. Four themes were identified in the literature: incorporating safety and quality in nursing education, re-designing conceptual frameworks, strategies to address content laden curricula, and teaching using alternative pedagogies. Synthesis of the recent literature in the field will assist faculty who are beginning the curriculum evaluation and revision process in their own schools.

    The purpose of this scoping review is to examine the nature of the interprofessional education (IPE) discussion that the Canadian nursing profession is having within the Canadian peer-reviewed nursing literature. An electronic database search of CINAHL was conducted using a modified Arksey & O'Malley scoping review framework. Peer-reviewed, English-language articles published in Canadian nursing journals from January 1981 to February 2016 were retrieved. Articles were included if they discussed IPE, or described an educational activity that met our conceptual definition of IPE. A total of 88 articles were screened, and 11 articles were eligible for analysis. Analysis revealed that this body of literature does not seem to be purposefully engaging Canadian nurses in a critical discourse about the role of IPE. The majority of articles located were reflective or commentaries. At the time of this review, there was a paucity of theoretically informed empirical research articles on IPE in the nursing literature. While IPE may be viewed by some critical scholars as a means of shifting the control of healthcare delivery traditionally held by medicine to other professions, our results suggest that this may not be the case in the Canadian nursing profession.

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

    2014-02-01

    The oncology population is particularly affected by hospital readmissions because hospitalized patients with cancer often have complex needs. The complexity and diversity of care requirements create substantial challenges in planning for appropriate postdischarge support. Implementing postdischarge telephone calls in the population of patients with cancer could offer a low-cost intervention to address the complex needs of patients during the transition from hospital to home. The goal of the current literature review is to provide an understanding about postdischarge telephone calls in patients with cancer. Findings from this review support the notion that discharge phone calls could improve care continuity for patients transitioning from hospital to home. The literature review outlines information related to telephone call content, timing, and structure for healthcare systems that want to use a postdischarge telephone intervention for patients with cancer. However, additional research is needed to develop and test cancer-specific protocols.

    In the present paper, the literature on the development of methods for histometric monitoring the quality of meats is reviewed. The value of specific techniques, statistical interpretation of results and the practicability of automation of histometric analysis are examined more closely. It is concluded from the study of the literature that histometric examination of meats allows an objective assessment of volume percentages of tissue components. When a distinct difference in contrast between various tissues is achieved by specific staining methods, developments in the field of image analysis systems will allow automation of the quantitative histological examination of meats.

  10. Antenatal Depression in East Asia: A Review of the Literature

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

    SUMMARY Objective The aim of this study is a systematic review of the literature on the strength and long-term behavior of zirconia FPDs. Methods The literature search was performed using as the primary source the Medline database. Were also imposed a set of inclusion and exclusion criteria in order to narrow the search to differentiate the two distinct parts in which it was structured the review. In addition, MeSH terms were applied to further refine the choice of articles more relevant to the review. In the part of the review concerning the long-term behavior of zirconia fixed partial dentures were considered useful only those studies with a minimum follow-up of one year. Results The search provided a total of 813 articles, but only 25 were considered for the review because they were the only ones who satisfied search criteria. In particular, 13 items relate to the mechanical strength of zirconia prostheses and 12 regarding the long term behavior of zirconia FPDs. The resistance values also exceed the 2000 N while the survival rate reaches to almost 94%. Conclusions Based on this review, Zirconia FPDs can be considered reliable products in both the anterior and posterior fields with survival rates comparable to traditional metal-ceramic prostheses.

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

    It can be very complicated to obtain relevant information through searching the medical literature if you do not know how it is organized and indexed or if you do not know how to use the specialized databases. For a successful review of the literature, you need to know what you are looking for and the key words for an effective search of the specialized databases and libraries and especially of the internet. It is essential to critically evaluate the information selected. Finally, using a reference manager can facilitate the gathering, organization, systematization, and integration of the bibliographic references in the documents generated in the study. This article aims to provide guidelines for efficient searching for information and for accurate, critical use of the literature. It makes recommendations about strategies for managing references to help to ensure the success of a research project.

    1987-04-01

    Literature pertinent to the ignition by smoldering cigarettes of upholstered furniture and mattresses (soft furnishings) was searched through early 1986. This included literature on the smoldering behavior of cigarettes in air; their behavior on a variety of substrates simulating soft furnishings; mechanism of smoldering in substrates; relative cigarette ignition resistance of substrates; and relative propensity of commercial cigarette packings to ignite substrates. According to the reviewed literature, the smoldering behavior of cigarettes on substrates differs from that of cigarettes burning in air: on substrates, cigarette temperatures tend to be lower, and burning rates slower. These differences seem to be larger for substrates which ignite than for those which self-extinguish after the cigarette burns out. The characteristics of soft furnishings which insure resistance to cigarette ignition have been established, but those of cigarettes with low propensity to ignite furnishings have not. No mathematical model has been reported for the interaction of cigarette and substrate, but some empirical data do exist.

    The aim of this study was to analyze the information available in the literature about the drugs that can be administered through hypodermoclysis and the resulting impact that this information may have on the routine of the pharmacist working at a hospital. The study was based on a review of the literature. The results showed positive points of the procedure, but little specific information about medications such as routes of administration, standard dilutions, optimal doses, etc. Thus, it was possible to verify that there is no definite information as to the correct way to administer the drugs in this route, even though this is an effective and safe option, according to the literature. The lack of information has a negative impact on the support provided by the pharmacist to the nursing staff to ensure that the drug actually reaches its therapeutic goals safely. PMID:25807246

  19. Literature review for oxalate oxidation processes and plutonium oxalate solubility

    Nash, C. A.

    2015-10-01

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

    Bronchogenic cysts are foregut-derived developmental anomalies most commonly encountered in the mediastinum and rarely in the abdomen or retroperitoneally. A comprehensive review of the English-language literature of subdiaphragmatic bronchogenic cysts (sBCs) revealed only 48 reported cases of sBC. Although most cases are incidentally discovered, preoperative differential diagnosis often includes tumors with malignant potential and necessitates surgical resection to obtain a definitive diagnosis. Herein, we describe a case of a 46-year-old female presenting with intermittent left flank pain, upon which computed tomography demonstrated a retroperitoneal mass. Upon resection, histopathology revealed the mass to be a thin-walled cystic mass lined by ciliated columnar cells and cartilage, consistent with a subdiaphragmatic bronchogenic cyst. A comprehensive literature review of sBC was also performed.

    Providing care to adolescents with cancer in the process of death and dying has been a great challenge for health professionals. This challenge is marked by a high emotional burden and specificities of this stage of human development. The purpose of the present study was to review the scientific literature regarding palliative care to adolescents with cancer. This study is a literature review, which data collection was performed using Lilacs, Medline, and PsycInfo, in addition to non-systematic databases. An analysis of the manuscripts revealed three themes: adolescence and its different definitions; the particularities of adolescents with cancer; and palliative care to adolescents with cancer. The study showed there is a scarcity of evidenced-based research defining the panorama of symptoms affecting the quality of life during palliative care and an absence of specific programs in the stage of fast changes that, alone, demand for adaptive efforts.

    The aim of this study was to review irritative and sensory disturbances following placement of dental implants. A literature search was made of PubMed for articles published between 2000 and 2010. Studies that reported sensory disturbances directly caused by the placement of dental implants were included. Sensory deficits or trigeminal neuropathy are caused by damage to the third branch of the trigeminal nerve during surgery. This manifests in the immediate postoperative period as a sensory deficit not usually associated with pain and generally transient. The literature reviewed reported irritative and sensory disturbances caused during surgery, after surgery, and as a result of complications. Postoperative pain appears after oral surgery as a result of inflammation associated with damage to tissue during surgery. Pain due to postoperative complications following implant placement was classified as neurogenic pain, peri-implant pain and bone pain.

    Breast cancer incidence and mortality rates are increasing in the Arab world and the involved women are often diagnosed at advanced stages of breast cancer. This literature review explores factors influencing Arab women's breast cancer screening behavior. Searched databases were: Medline, PubMed, Cochrane Database of Systematic Reviews, CINAHL Plus, Google Scholar, Index Medicus for WHO Eastern Mediterranean, and Asian Pacific Journal of Cancer Prevention. Breast cancer screening participation rates are low. Screening programs are opportunistic and relatively new to the region. Knowledge amongst women and health care providers, professional recommendation, socio-demographic factors, cultural traditions, beliefs, religious, social support, accessibility and perceived effectiveness of screening influence screening behavior.

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

    Nurses are frequently confronted with ethical dilemmas in their nursing practice. As a consequence, nurses report experiencing moral distress. The aim of this review was to synthesize the available quantitative evidence in the literature on moral distress experienced by nurses. We appraised 19 articles published between January 1984 and December 2011. This review revealed that many nurses experience moral distress associated with difficult care situations and feel burnout, which can have an impact on their professional position. Further research is required to examine worksite strategies to support nurses in these situations and to develop coping strategies for dealing with moral distress.

    A review by Catchpole et al (2009) into the causes and types of harm experienced by the surgical patient emphasised the high risk nature of the perioperative period. Investigations into recent failures at NHS organisations have emphasised the relevance of non-technical skills education in improving clinical performance and patient outcomes. However, scrub practitioner non-technical skills are often developed on a tacit basis, making assessment of performance difficult. This literature review identifies strategies that facilitate assessment of non-technical skills during surgery. Recommendations are made that will assist scrub practitioners in using a validated scrub practitioner non-technical skills assessment framework reliably. PMID:26016259

    2016-01-01

    Investigators often have multiple suspects to interview in order to determine whether they are guilty or innocent of a crime. Nevertheless, co-offending has been significantly neglected within the deception detection literature. The current review is the first of its kind to discuss co-offending and the importance of examining the detection of deception within groups. Groups of suspects can be interviewed separately (individual interviewing) or simultaneously (collective interviewing) and these differing interviewing styles are assessed throughout the review. The review emphasizes the differences between lone individuals and groups. It focuses on the theoretical implications of group deceit and the reasons why groups need to be understood in terms of investigative interviewing and deception detection if all types of crime-related incidents are to be recognized and dealt with appropriately. Group strategies, consistency within- and between-statements, joint memory, and group dynamics are referred to throughout the review and the importance of developing interview protocols specifically for groups is discussed. The review concludes by identifying the gaps in the literature and suggesting ideas for future research, highlighting that more research is required if we are to obtain a true understanding of the deception occurring within groups and how best to detect it.

    In a number of countries, including Taiwan, the prevalence of childhood obesity has been steadily increasing. A study to assess school nurses' perspective on their role in supporting children and preventing childhood obesity in Taiwan is currently being undertaken. A search of the literature reveals that most research publications come from the West and these studies have been useful. However, it is important to isolate the research and policy materials that take into account the contextually and culturally relevant factors in Taiwan and neighboring countries. Findings from a review of the Taiwanese literature are presented in this paper. The literature reveals the factors associated with the prevalence of childhood obesity and prevention strategies. A significant proportion of the research is medical and focuses on cardiovascular disease rather than health promotion and education. However, there are findings in this review that generally support health promotion activities and programs that are school based. There appears to be an urgent need for investment in research that assesses the long-term effectiveness of interventions designed to promote the maintenance of healthy weight during childhood in the Taiwanese society. Western literature is referred to occasionally in this paper in order to introduce an issue or to compare with a Taiwanese paper.

    The International Emergency Medicine (IEM) Literature Review aims to highlight and disseminate high-quality global EM research in the fields of EM development, disaster and humanitarian response, and emergency care in resource-limited settings. For this review, we conducted a Medline search for articles published between January 1 and December 31, 2010, using a set of international and EM search terms and a manual search of journals that have produced large numbers of IEM articles for past reviews. This search produced 6,936 articles, which were divided among 20 reviewers who screened them using established inclusion and exclusion criteria to select articles relevant to the field of IEM. Two-hundred articles were selected by at least one reviewer and approved by an editor for scoring. Two independent reviewers using a standardized and predetermined set of criteria then scored each of the 200 articles. The 27 top-scoring articles were chosen for full review. The articles this year trended toward evidence-based research for treatment and care options in resource-limited settings, with an emphasis on childhood illness and obstetric care. These articles represent examples of high-quality international emergency research that is currently ongoing in high-, middle-, and low-income countries alike. This article is not intended to serve as a systematic review or clinical guideline but is instead meant to be a selection of current high-quality IEM literature, with the hope that it will foster further growth in the field, highlight evidence-based practice, and encourage discourse.

    A case is presented of a 49-year-old man who amputated his penis following instructions that he had obtained from the Internet. The patient had a long-standing amputee fetish, which evolved into eroticized genital mutilation.

    Studies on family violence have analyzed the phenomenon from psychological, social, and cultural perspectives. A review of the literature shows that the available evidence is not contradictory, leading to the conclusion that a comprehensive theory of violence at home must take into account factors at these several levels, placing individual functioning within the social group and within the culture norms by which the group operates. A theory of violence at home, and suggestions for further research, are offered.

    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.

  16. Review of the epidemiologic literature on residential exposure to perchloroethylene.

    PubMed

    Bukowski, John A

    2011-10-01

    Perchloroethylene is a solvent that is widely used for dry cleaning. There has been considerable interest in the toxicity of this chemical because of the potential for low-level exposure among a large portion of the US population. Although substantial epidemiologic literature exists on high-level occupational exposure to perchloroethylene, there are relatively few studies dealing with lower-level residential exposure. In the current paper, the author reviews this limited residential literature, with special emphasis on strengths, limitations, and consistency. Reviewed studies primarily address neurobehavioral, cancer, and reproductive endpoints. Most studies used an ecological or cross-sectional design, with exposure defined by either drinking-water contamination or proximity to dry cleaning. In general, reviewed studies were highly exploratory, with inconsistencies and potential for bias that detract from interpretation of study findings. The magnitudes of reported effects are frequently incompatible with the effects reported from much higher occupational and human-chamber exposures. Overall, few reliable conclusions can be drawn from this sparse and highly limited body of literature.

  17. Citicoline in Addictive Disorders: A Review of the Literature

    PubMed Central

    Wignall, Nicholas D.; Brown, E. Sherwood

    2014-01-01

    Background Citicoline is a dietary supplement that has been used as a neuroprotective agent for neurological disorders such as stroke and dementia. Citicoline influences acetylcholine, dopamine, and glutamate neurotransmitter systems; serves as an intermediate in phospholipid metabolism; and enhances the integrity of neuronal membranes. Interest has grown in citicoline as a treatment for addiction since it may have beneficial effects on craving, withdrawal symptoms, and cognitive functioning, as well as the ability to attenuate the neurotoxic effects of drugs of abuse. Objectives To review the literature on citicoline’s use in addictive disorders. Methods Using PubMed we conducted a narrative review of the clinical literature on citicoline related to addictive disorders from the years 1900 to 2013 using the following keywords: citicoline, CDP-choline, addiction, cocaine, alcohol, substance abuse, and substance dependence. Out of approximately 900 first hits, nine clinical studies have been included in this review. Results Most addiction research investigated citicoline for cocaine use. The findings suggest that it is safe and well tolerated. Furthermore, citicoline appears to decrease craving and is associated with a reduction in cocaine use, at least at high doses in patients with both bipolar disorder and cocaine dependence. Limited data suggest citicoline may also hold promise for alcohol and cannabis dependence and in reducing food consumption. Conclusions Currently, there is limited research on the efficacy of citicoline for addictive disorders, but the available literature suggests promising results. Future research should employ larger sample sizes, increased dosing, and more complex study designs. PMID:24950234

    2004-09-22

    This paper provides a review of examples from the literature of shared communication resources and of agencies and/or organizations that share communication resources. The primary emphasis is on rural, intelligent transportation system communications involving transit. Citations will not be limited, however, to rural activities, or to ITS implementation, or even to transit. In addition, the term ''communication'' will be broadly applied to include all information resources. Literature references to issues that contribute to both successful and failed efforts at sharing communication resources are reviewed. The findings of this literature review indicate that: (1) The most frequently shared communication resources are information/data resources, (2) Telecommunications infrastructure and technologies are the next most frequently shared resources, (3) When resources are successfully shared, all parties benefit, (4) A few unsuccessful attempts of sharing resources have been recorded, along with lessons learned, (5) Impediments to sharing include security issues, concerns over system availability and reliability, service quality and performance, and institutional barriers, (6) Advantages of sharing include financial benefits to agencies from using shared resources and benefits to the public in terms of congestion mitigation, information transfer (e.g., traveler information systems), mobility (e.g., welfare-to-work paratransit), and safety (e.g., speed of incident response, incident avoidance), (7) Technology-based solutions exist to address technology-based concerns, and (8) Institutional issues can be addressed through leadership, enhanced knowledge and skills, open communication, responsiveness, and attractive pricing structures.

    2015-01-01

    Despite an increasing literature related to elder abuse, sexual abuse of older persons in general and of vulnerable adults living in nursing homes in particular is still sparsely described. The purpose of this study was to assess the state of knowledge on the subject of sexual abuse against older nursing home residents through a literature review. Systematic searches in reference databases including Cinahl, Medline, OVID Nursing Database, ISI Web of Science, PsycINFO, Cochrane Library, and SveMed + were conducted. Through several phases of selection of the articles, using strict inclusion and exclusion criteria, six articles were chosen for a deeper examination. Findings from the review show that sexual abuse occurs in nursing homes and that both older women and men are victims of sexual abuse. Perpetrators appear mainly to be staff and other residents and mainly to be men, but also women abuse both older men and older women. Findings from the literature review show that there is a need for knowledge and further research on the topic of sexual abuse against older residents in nursing homes. Furthermore, there is a need for good policies and reporting systems, as an important step in seriously addressing sexual abuse against older persons. PMID:25642347

  1. Immunomodulatory dietary polysaccharides: a systematic review of the literature

    PubMed Central

    2010-01-01

    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 mushroom improved survival and

    Objective The purpose of this study was to summarize sport concussion incidence data, identify sports that present higher injury frequency, reveal the degree of risk in some lesser-known sports, and outline specific details within the sports literature that raise additional concerns, such as helmet-to-helmet contact and player positions that experience frequent impact. Methods A systematic literature review of Pub Med using keyword search on injury, concussion, and sports was performed through May 2012. Abstracts were identified, selections were made based upon inclusion criteria, and full-length articles were obtained. Additional articles were considered following review of reference sections. Articles were reviewed and tabulated according to sport. Results Two hundred eighty-nine articles were screened, and 62 articles were reviewed. The overall incidence of concussion in sport ranged from 0.1 to 21.5 per 1000 athletic exposures. The lowest incidence was reported in swimming and diving. Concussion incidence was highest in Canadian junior ice hockey, but elevated incidence in American football remains a concern because of the large number of participants. Conclusions The literature reviewed included incidence of concussion on the field of play under real-world conditions and influenced by the current culture of sport. The studies examined in this article show that there is risk of concussion in nearly every sport. Some sports have higher concussion frequency than others, which may depend upon the forces and roles of the positions played in these sports. Younger athletes have a higher incidence of concussion, and female incidence is greater than male in many comparable sports. Headgear may reduce concussion in some sports but may also give athletes a false sense of protection. PMID:24396326

    The subspecialty of international emergency medicine (IEM) continues to grow within the United States, just as the specialty of emergency medicine (EM) continues to spread to both developed and developing countries around the world. One of the greatest obstacles, however, faced by IEM researchers and practitioners alike, remains the lack of a high-quality, consolidated, and easily accessible evidence-base of literature. In response to this perceived need, members of the Emergency Medicine Resident Association (EMRA) International Emergency Medicine Committee, in conjunction with members of the Society for Academic Emergency Medicine (SAEM) International Health Interest Group, have embarked on the task of creating a recurring review of IEM literature. This publication represents the third annual review, covering the top 30 IEM research articles published in 2007. Articles were selected for the review according to explicit, predetermined criteria that included both methodologic quality and perceived impact of the research. It is hoped that this annual review will act as a forum for disseminating best practices, while also stimulating further research in the field of IEM.

    2006-01-01

    The aim of the paper is to critically review the notion of social capital and review empirical literature on the association between social capital and health across countries. The methodology used for the review includes a systematic search on electronic databases for peer-reviewed published literature. We categorize studies according to level of analysis (single and multilevel) and examine whether studies reveal a significant health impact of individual and area level social capital. We compare the study conclusions according to the country's degrees of economic egalitarianism. Regardless of study design, our findings indicate that a positive association (fixed effect) exists between social capital and better health irrespective of countries degree of egalitarianism. However, we find that the between-area variance (random effect) in health tends to be lower in more egalitarian countries than in less egalitarian countries. Our tentative conclusion is that an association between social capital and health at the individual level is robust with respect to the degree of egalitarianism within a country. Area level or contextual social capital may be less salient in egalitarian countries in explaining health differences across places. PMID:16597324

    2015-01-01

    The purpose of this literature review is to critically evaluate published protocols on polypharmacy in adults ages 65 and older that are currently used in primary care settings that may potentially lead to fewer adverse drug events. A review of OVID, CINAHL, EBSCO, Cochrane Library, Medline, and PubMed databases was completed using the following key words: protocol, guideline, geriatrics, elderly, older adult, polypharmacy, and primary care. Inclusion criteria were: articles in medical, nursing, and pharmacology journals with an intervention, protocol, or guideline addressing polypharmacy that lead to fewer adverse drug events. Qualitative and quantitative studies were included. Exclusion criteria were: publications prior to the year 1992. A gap exists in the literature. No standardized protocol for addressing polypharmacy in the primary care setting was found. Mnemonics, algorithms, clinical practice guidelines, and clinical strategies for addressing polypharmacy in a variety of health care settings were found throughout the literature. Several screening instruments for use in primary care to assess potentially inappropriate prescription of medications in the elderly, such as the Beers Criteria and the STOPP screening tool, were identified. However, these screening instruments were not included in a standardized protocol to manage polypharmacy in primary care. Polypharmacy in the elderly is a critical problem that may result in adverse drug events such as falls, hospitalizations, and increased expenditures for both the patient and the health care system. No standardized protocols to address polypharmacy specific to the primary care setting were identified in this review of the literature. Given the growing population of elderly in this country and the high number of medications they consume, it is critical to focus on the utilization of a standardized protocol to address the potential harm of polypharmacy in the primary care setting and evaluate its effects on

    Intelligent agents and healthcare have been intimately linked in the last years. The intrinsic complexity and diversity of care can be tackled with the flexibility, dynamics and reliability of multi-agent systems. The purpose of this review is to show the feasibility of applying intelligent agents in the healthcare domain and use the findings to provide a discussion of current trends and devise future research directions. A review of the most recent literature (2009-2014) of applications of agents in healthcare is discussed, and two classifications considering the main goal of the health systems as well as the main actors involved have been investigated. This review shows that the number of published works exhibits a growing interest of researchers in this field in a wide range of applications.

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

    PubMed Central

    2011-01-01

    Background Wind power has been harnessed as a source of power around the world. Debate is ongoing with respect to the relationship between reported health effects and wind turbines, specifically in terms of audible and inaudible noise. As a result, minimum setback distances have been established world-wide to reduce or avoid potential complaints from, or potential effects to, people living in proximity to wind turbines. People interested in this debate turn to two sources of information to make informed decisions: scientific peer-reviewed studies published in scientific journals and the popular literature and internet. Methods The purpose of this paper is to review the peer-reviewed scientific literature, government agency reports, and the most prominent information found in the popular literature. Combinations of key words were entered into the Thomson Reuters Web of KnowledgeSM and the internet search engine Google. The review was conducted in the spirit of the evaluation process outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Results Conclusions of the peer reviewed literature differ in some ways from those in the popular literature. In peer reviewed studies, wind turbine annoyance has been statistically associated with wind turbine noise, but found to be more strongly related to visual impact, attitude to wind turbines and sensitivity to noise. To date, no peer reviewed articles demonstrate a direct causal link between people living in proximity to modern wind turbines, the noise they emit and resulting physiological health effects. If anything, reported health effects are likely attributed to a number of environmental stressors that result in an annoyed/stressed state in a segment of the population. In the popular literature, self-reported health outcomes are related to distance from turbines and the claim is made that infrasound is the causative factor for the reported effects, even though sound pressure levels are not measured

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

    2014-01-01

    Background Adjacent segment disease has become a common topic in spine surgery circles because of the significant increase in fusion surgery in recent years and the development of motion preservation technologies that theoretically should lead to a decrease in this pathology. The purpose of this review is to organize the evidence available in the current literature on this subject. Methods For this literature review, a search was conducted in PubMed with the following keywords: adjacent segment degeneration and disease. Selection, review, and analysis of the literature were completed according to level of evidence. Results The PubMed search identified 850 articles, from which 41 articles were selected and reviewed. The incidence of adjacent segment disease in the cervical spine is close to 3% without a significant statistical difference between surgical techniques (fusion vs arthroplasty). Authors report the incidence of adjacent segment disease in the lumbar spine to range from 2% to 14%. Damage to the posterior ligamentous complex and sagittal imbalances are important risk factors for both degeneration and disease. Conclusion Insufficient evidence exists at this point to support the idea that total disc arthroplasty is superior to fusion procedures in minimizing the incidence of adjacent segment disease. The etiology is most likely multifactorial but it is becoming abundantly clear that adjacent segment disease is not caused by motion segment fusion alone. Fusion plus the presence of abnormal end-fusion alignment appears to be a major factor in creating end-fusion stresses that result in adjacent segment degeneration and subsequent disease. The data presented cast further doubt on previously established rationales for total disc arthroplasty, at least with regard to the effect of total disc arthroplasty on adjacent segment degeneration pathology.

    Ishikawa, Keiko; Thibeault, Susan

    2010-01-01

    Voice rest is commonly prescribed after vocal fold surgery to promote wound healing of the vocal fold. Currently, there is no standard protocol that is established based on biological evidence. In orthopedic rehabilitation, long-term rest is found to be less effective for connective tissue healing than exercise. Connective tissue healing is also an important factor for successful voice rehabilitation; however, whether this concept can be extrapolated to voice rehabilitation is unknown. The purpose of this article is to review current clinical and basic science literature to examine the effect of voice rest in post-surgical rehabilitation. First, we present a summary of clinical literature that pertains to voice rest. Second, description of connective tissue that are involved in orthopedic and voice rehabilitation, specifically, ligament and lamina propria, respectively, and their wound healing process are offered. Third, a summary of the literature from orthopedic research on the effect of rest versus exercise is presented. Lastly, it summarizes in vitro and in vivo studies that examined the effect of mechanical stress on vocal fold tissue. Current literature suggests that there is a lack of clinical evidence that supports a specific type and duration of voice rest, and extrapolation of the findings from orthopedic research may be unreasonable due to the morphological and biochemical difference between the tissues. In order to determine the effect of voice rest, further elucidation of vocal fold wound healing process and the effect of mechanical stress on vocal fold tissue remodeling are needed. PMID:19660903

  12. Culture change in care homes: a literature review.

    PubMed

    Wild, Deirdre; Kydd, Angela

    2016-08-01

    This article is the first of a two-part series that explores a programme of culture change in care homes. A UK care home company sought the authors' expertise to design and facilitate an independent programme of learning to encourage and support staff in two of its homes to become the architects of their own quality improvement. The article reviews the literature that was an essential information base for the authors in their dual roles as designers of the learning programme and facilitators of its delivery to participant staff. The literature is necessarily broad in reflecting the nature and context of care homes, residents' needs and wants from care, and the particular challenges that might be faced by care home staff and managers when making quality improvements. In the second article, the reality of running the programme in the two homes is described. PMID:27573965

    Ameloblastoma has intrigued clinicians as well as pathologists due to its diverse clinical behavior and histomorphologic presentations. Keratoameloblastoma is a rare histologic sub type, characterized by extensive keratin formation within ameloblastic epithelium, with only a handful number of cases described in the literature. Here, we report a case of this uncommon sub type of ameloblastoma in a young female patient presenting as an extensive lesion in mandibular ramus area. The radiological and fine needle aspiration findings suggested of a keratinizing cystic lesion and incisional biopsy showed features of ameloblastoma. Patient underwent segmental mandibulectomy and histological examination of excisional specimen revealed features of ameloblastoma with abundant keratinization leading to a diagnosis of keratoameloblastoma. The diagnostic pitfalls related with the lesion have been discussed along with a short review of the literature. PMID:25426155

    Calcification rarely occurs in vestibular schwannoma (VS), and only seven cases of calcified VS have been reported in the literature. Here, we report a 48-year-old man with VS, who had a history of progressive left-sided hearing loss for 3 years. Neurological examination revealed that he had left-sided hearing loss and left cerebellar ataxia. Magnetic resonance imaging and computerized tomography angiography showed a mass with calcification in the left cerebellopontine angle (CPA). The tumor was successfully removed via suboccipital craniotomy, and postoperative histopathology showed that the tumor was a schwannoma. We reviewed seven cases of calcified VS that were previously reported in the literature, and we analyzed and summarized the characteristics of these tumors, including the calcification, texture, and blood supply. We conclude that calcification in VS is associated with its texture and blood supply, and these characteristics affect the surgical removal of the tumor.

    2014-04-01

    Around the world, an increasing number of grandparents are raising grandchildren in households without a biological parent. This is no less true in the United States, where grandparents raising grandchildren are at increased risk for depression and declining physical health. The purpose of this article is to explore the recent literature as it relates to the psychological and/or physical health of grandparents raising grandchildren. On reviewing 19 articles from the past 10 years, it is clear that the literature consistently verifies the health risks, especially depression, for grandparents raising grandchildren; however, the lack of research regarding grandfathers and non-African American caregivers is apparent. The factors influencing grandparents raising grandchildren are numerous, which calls for care providers to assess the needs, situations, and perceptions of grandparents individually. Finally, a need has arisen for more research suggesting and validating interventions that health care providers can use to support this population of older adults. PMID:24568146

    Food and nutrition education is viewed as a key strategy for promoting healthy eating habits, and the school is an appropriate space for developing these activities. The objective of this study was to describe and analyze the scientific literature on intervention studies on food and nutrition education in Brazilian schools. A literature review was conducted, selecting articles published from 2000 to 2011. Despite the topic's current importance, there were few articles, and most were published after 2009. The main results showed improvement in the children's nutritional knowledge and food choices. However, most studies that performed anthropometric measurements failed to show changes in nutritional status. In addition, the studies chose designs based on epidemiological intervention studies, indicating the need for interventions based on innovative health education methodologies and research models that are consistent with the study's objects.

    2015-05-01

    Facial nerve paralysis because of penetrating trauma through the external auditory canal is extremely rare, with a paucity of published literature. The objective of this study is to review the literature on transtympanic facial nerve paralysis and increase physician awareness of this uncommon injury through discussion of its clinical presentation, management and prognosis. We also aim to improve patient outcomes in those that have sustained this type of injury by suggesting an optimal management plan. In this case report, we present the case of a 46-year-old white woman who sustained a unilateral facial nerve paresis because of a garfish penetrating her tympanic membrane and causing direct damage to the tympanic portion of her facial nerve. On follow-up after 12 months, her facial nerve function has largely returned to normal. Transtympanic facial nerve paralysis is a rare injury but can have a favorable prognosis if managed effectively.

    2016-06-01

    Psoriatic arthritis (PsA) is characterized by chronic inflammation of peripheral joints and axial skeleton, associated with a strong genetic background. Clinics include enthesitis or dactylitis and extra-articular involvement as uveitis or inflammatory bowel disease, while treatment options range from nonsteroidal anti-inflammatory drugs (NSAIDs) to biologics, targeting TNF α or Th17. No serum autoantibody is associated with PsA, while other biomarkers have been proposed for early diagnosis or to predict treatment response. To better discuss this area of growing interest we performed a systematic review of the literature on biomarkers in PsA. Our research retrieved 408 papers, and 38 were included in the analysis. Based on the available literature, we draw some recommendations for the use of biomarkers in the management of patients with PsA. PMID:26821681

    2003-01-01

    This article explores current research on online cancer support groups. A review of the literature revealed 9 research articles (describing 10 research studies) that focused on computer-mediated or Internet cancer support groups. The researchers in 9 of the 10 studies concluded that online cancer support groups helped people cope more effectively with their disease. Most of the research studies had small sample sizes. Six of the 10 studies did not include men, and six focused on Caucasian women with breast cancer. Information seeking/giving was prevalent in the online groups. Gender differences, negative psychological effects, and barriers to using online groups were identified. The few studies that were found in the literature suffered from a lack of experimental design, small and homogenous samples, and lack of outcome measures, thereby limiting applicability of results.

    Primary thyroid leiomyosarcoma (LMS) is an extremely rare soft tissue cancer; only 22 cases have been reported in the literature to date. In the current study, the case of an 83-year-old male patient who presented with a neck mass that had grown rapidly over the previous 3 months is reported. The patient underwent thyroid lobectomy twice and two cycles of immunotherapy for the treatment of primary thyroid LMS; however, he succumbed to the disease 5 months after the second surgery. An accurate diagnosis of primary thyroid LMS is difficult, as the disease is often misdiagnosed as anaplastic carcinoma, and requires the combined assessment of clinical, imaging and pathological data. Diagnosis of the current patient with primary thyroid LMS and a comprehensive review of the relevant literature are presented herein. PMID:27313727

    The smoking behaviour of nurses has been widely debated in the context of their professional role and responsibilities. There has been much speculation about why nurses smoke and possible explanations include a stressful nursing environment, peer pressure and socio economic status and education. This paper provides an overview of the literature which offers insights into the reasons why nurses smoke and compares the findings from this literature with those studies examining the smoking behaviour of women in general and young women in particular. This review reveals that many students take up smoking before commencing their training and the factors which influence nurses smoking are similar to those that influence similar groups of females in the general population.

    2015-09-01

    Gynecomastia is defined as excess glandular growth of breast tissue in males. It is a noticeable physical difference that commonly affects males in adolescence and old age. While often transient in nature, gynecomastia persists indefinitely in 10% of cases. Much of the literature on gynecomastia has focused on etiology and management. Little research has been done regarding the impact of gynecomastia on one's mental health and quality of life; however, some studies have suggested various psychosocial and psychological consequences related to gynecomastia. These consequences include but are not limited to depression, anxiety, disordered eating, body dissatisfaction, and reduced self-esteem. The aims of this paper are to review the current gynecomastia literature, bring awareness to an understudied but troubled population, and discuss directions for future work, including offering extant models of body image to guide researchers.

    Angiolipomas are frequently observed benign tumors. They have a typical vascular component and are often located in subcutaneous tissues, and more rarely, in the gastrointestinal tract. We present the case of a 58-year-old man who complained of abdominal discomfort in the left lower quadrant and two to three bloody stools a day without any obvious etiology. These symptom became more severe in the next three days, due to a large angiolipoma located in the descending colon, which was diagnosed intraoperatively. In a literature review, we found only 22 cases of angiolipomas involving the gastrointestinal tract which are reported in the literature from 1960 to 2012 in PubMed; the key words used in the search are gastrointestinal tract angiolipoma, esophagus, stomach, duodenum, intestine, ileocecal junction, colon, rectum angiolipomas. Colon angiolipoma with intussusception, as seen in this case, is rare and may require emergent surgical intervention.

    Health research has relied on ethical principles, such as those of the Belmont Report, to protect the rights and well-being of research participants. Community-based participatory research (CBPR), however, must also consider the rights and well-being of communities. This requires additional ethical considerations that have been extensively discussed but not synthesized in the CBPR literature. We conducted a comprehensive thematic literature review and summarized empirically grounded discussions of ethics in CBPR, with a focus on the value of the Belmont principles in CBPR, additional essential components of ethical CBPR, the ethical challenges CBPR practitioners face, and strategies to ensure that CBPR meets ethical standards. Our study provides a foundation for developing a working definition and a conceptual model of ethical CBPR. PMID:24134352

  5. Immunizations and autism: a review of the literature.

    PubMed

    2006-11-01

    Because of a temporal correlation between the first notable signs and symptoms of autism and the routine childhood vaccination schedule, many parents have become increasingly concerned regarding the possible etiologic role vaccines may play in the development of autism. In particular, some have suggested an association between the Measles-Mumps-Rubella vaccine and autism. Our literature review found very few studies supporting this theory, with the overwhelming majority showing no causal association between the Measles-Mumps-Rubella vaccine and autism. The vaccine preservative thimerosal has alternatively been hypothesized to have a possible causal role in autism. Again, no convincing evidence was found to support this claim, nor for the use of chelation therapy in autism. With decreasing uptake of immunizations in children and the inevitable occurrence of measles outbreaks, it is important that clinicians be aware of the literature concerning vaccinations and autism so that they may have informed discussions with parents and caregivers.

    This paper reviews the nontechnical barriers to solar energy use, drawing on recent literature to help identify key barriers that must be addressed as part of the Technology Acceptance efforts under the U.S. Department of Energy (DOE) Solar America Initiative. A broad literature search yielded more than 400 references, which were narrowed to 19 recent documents on nontechnical barriers to the use of solar energy and other energy efficiency and renewable energy (EE/RE) technologies. Some of the most frequently identified barriers included lack of government policy supporting EE/RE, lack of information dissemination and consumer awareness about energy and EE/RE, high cost of solar and other EE/RE technologies compared with conventional energy, and inadequate financing options for EE/RE projects.

    2015-01-01

    This extensive literature review focuses on cardiovascular risk factors in young adults, with an emphasis on hyperlipidemia and hypertension. Multiple studies have confirmed that hyperlipidemia and hypertension during young adulthood are associated with coronary heart disease (CHD) in later decades, and CHD is one type of cardiovascular disease. The primary risk factors identified in the literature that are predictive of CHD are age; gender; race/ethnicity; smoking status; high blood pressure; and elevated lipid levels, especially low-density lipoprotein cholesterol. The current guidelines are insufficient to address screening and treatment in young adults with cardiovascular risk factors. Future studies are warranted to confirm the extent of cardiovascular risks in young adults, which can then be targeted to this population for prevention and intervention strategies.

    Retinoblastoma (RB) is the most common intraocular malignancy in children. Recently, there have been significant advances made in the molecular pathology and the management of the disease. Last decade has witnessed better understanding of the genetics of RB, the discovery of new tumor markers expressed by the RB tumors, the identification of high-risk histopathological factors following enucleation, and newer methods of treatment including periocular chemotherapy and superselective intraarterial chemotherapy. All these advances have translated in improved survival rates for the affected children, improved rates of eye salvage, and improved visual outcomes. This article briefly reviews these advances. Method of Literature Search: Literature on the Medline database was searched using the PubMed interface. The search strategy included MeSH and natural language terms using the keywords mentioned. Reference lists in retrieved articles and textbooks were also searched for relevant references. PMID:22279397

    2010-01-01

    Prevalence of psychostimulant use is high, and raising in several countries. Nicotine is the legal stimulant causing the most important public health impact. Cocaine ranks among the most used illicit substances after cannabis. Stimulant medications are frequently misused. Psychostimulants can lead to addiction, have physical, psychological and social health consequences and can induce a great disease burden. The aim of the present article is to provide a literature review on the health effects of stimulants as potential drugs of abuse. It will cover essentially cocaine, amphetamines and its derivatives (including methamphetamines and 3-4-methylenedioxymethamphetamine, ecstasy), nicotine, caffeine and khat, and touch upon the issues of prescribed substances (anti-depressants, weight control medications, attention-deficit hyperactivity disorder medications, hypersomniac disorder). Their pharmacology, addictive potential, health consequences and treatment will be discussed. We used Medline for the literature review from 1990 to the date of this review, and mention the findings of human and animal studies (the latter only if they are of clinical relevance).

    2015-01-01

    Evidence-based practices search for the best available scientific evidence to support problem solving and decision making. Because of the complexity and amount of information related to health care, the results of methodologically sound scientific papers must be integrated by performing literature reviews. Although endotracheal suctioning is the most frequently performed invasive procedure in intubated newborns in neonatal intensive care units, few Brazilian studies of good methodological quality have examined this practice, and a national consensus or standardization of this technique is lacking. Therefore, the purpose of this study was to review secondary studies on the subject to establish recommendations for endotracheal suctioning in intubated newborns and promote the adoption of best-practice concepts when conducting this procedure. An integrative literature review was performed, and the recommendations of this study are to only perform endotracheal suctioning in newborns when there are signs of tracheal secretions and to avoid routinely performing the procedure. In addition, endotracheal suctioning should be conducted by at least two people, the suctioning time should be less than 15 seconds, the negative suction pressure should be below 100 mmHg, and hyperoxygenation should not be used on a routine basis. If indicated, oxygenation is recommended with an inspired oxygen fraction value that is 10 to 20% greater than the value of the previous fraction, and it should be performed 30 to 60 seconds before, during and 1 minute after the procedure. Saline instillation should not be performed routinely, and the standards for invasive procedures must be respected.

    Despite the proliferation of patient navigation programs designed to increase timely receipt of health care, little is known about the content and delivery of patient navigation training, or best practices in this arena. The current study begins to address these gaps in understanding, as it is the first study to comprehensively review descriptions of patient navigation training in the peer-reviewed research literature. Seventy-five patient navigation efficacy studies published since 1995, identified through PubMed and by the authors, were included in this narrative review. Fifty-nine of the included studies (79%) mentioned patient navigation training, and 55 of these studies additionally provided a description of training. Most studies did not thoroughly document patient navigation training practices. Additionally, several topics integral to the role of patient navigators, as well as components of training central to successful adult learning, were not commonly described in the research literature. Descriptions of training also varied widely across studies in terms of duration, location, format, learning strategies employed, occupation of trainer, and content. These findings demonstrate the need for established standards of navigator training as well as for future research on the optimal delivery and content of patient navigation training.

    Various types of disasters, such as natural disasters, industrial accidents and crimes, often occur in the workplace and many workers are involved in them. They are not only directly injured but also exposed to health hazards, such as terrible experiences and chemical materials. Occupational health specialists are expected to act to minimize the adverse health effects from them speedily and appropriately. It is assumed that learning from past cases is effective for such occupational health activities. Accordingly, we conducted a literature review about the health effects on workers in disasters. Relevant literature was searched in PubMed. Twenty four studies were extracted by our criteria. In this review, subjects were limited to general workers by excluding professional workers, such as emergency services and firefighters. The health effects were examined as follows: mental health (13 articles), respiratory (5), cardiovascular (2), musculoskeletal (1), skin (1), nervous (1), and general (1). It was obvious that few studies on general workers were published when considering large number of disasters in the past. Factors that affect health outcomes were categorized into ① those related to devastation of environment of work and life due to disaster, and ② those related to health hazards due to disasters. Knowledge from the review will support the activities of occupational health specialists during disasters, but additional studies are needed.

    2015-01-01

    Acrylic resin is a widely used material in clinical practice, and a satisfactory biocompatibility is essential. When the resin polymerization reaction is incomplete, residual monomers are released into the oral cavity. The aim of this study was to evaluate, through a literature review, the cytotoxicity caused by the denture base acrylic resin used, and its components. The selection of published studies was performed on the Pubmed database from January 2008 to July 2013. The keywords used were: "cytotoxicity and acrylic resins", "cytotoxicity and denture base resins" and "cytotoxicity and oral prosthesis". Inclusion criteria were: in vitro studies and literature reviews published in English that evaluated the acrylic resin cytotoxicity for denture base and its components. Studies with no reference to the search strategy were excluded. A total of 182 articles were found. Among these, only 13 were included for writing this review. The MTT test is the most common test used to evaluate acrylic resin cytotoxicity. Auto-polymerized resin is more cytotoxic than heat-polymerized resin because of its higher quantity of residual monomers which cause cell and tissue changes in the oral mucosa. However, more studies are necessary for the development of biocompatible materials.

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

If indicated, oxygenation is recommended with an inspired oxygen fraction value that is 10 to 20% greater than the value of the previous fraction, and it should be performed 30 to 60 seconds before, during and 1 minute after the procedure. Saline instillation should not be performed routinely, and the standards for invasive procedures must be respected. PMID:26465249

  17. Home care in Europe: a systematic literature review

    PubMed Central

    2011-01-01

    Background Health and social services provided at home are becoming increasingly important. Hence, there is a need for information on home care in Europe. The objective of this literature review was to respond to this need by systematically describing what has been reported on home care in Europe in the scientific literature over the past decade. Methods A systematic literature search was performed for papers on home care published in English, using the following data bases: Cinahl, the Cochrane Library, Embase, Medline, PsycINFO, Sociological Abstracts, Social Services Abstracts, and Social Care Online. Studies were only included if they complied with the definition of home care, were published between January 1998 and October 2009, and dealt with at least one of the 31 specified countries. Clinical interventions, instrument developments, local projects and reviews were excluded. The data extracted included: the characteristics of the study and aspects of home care 'policy & regulation', 'financing', 'organisation & service delivery', and 'clients & informal carers'. Results Seventy-four out of 5,133 potentially relevant studies met the inclusion criteria, providing information on 18 countries. Many focused on the characteristics of home care recipients and on the organisation of home care. Geographical inequalities, market forces, quality and integration of services were also among the issues frequently discussed. Conclusions Home care systems appeared to differ both between and within countries. The papers included, however, provided only a limited picture of home care. Many studies only focused on one aspect of the home care system and international comparative studies were rare. Furthermore, little information emerged on home care financing and on home care in general in Eastern Europe. This review clearly shows the need for more scientific publications on home care, especially studies comparing countries. A comprehensive and more complete insight into the

    The aim of this study was to review the literature on human studies of drug therapy in cardiac arrest during the last 25 years. In May 2015, a systematic literature search was performed in PubMed, Embase, the Cochrane Library, and CRD databases. Prospective interventional and observational studies evaluating a specified drug therapy in human cardiac arrest reporting a clinical endpoint [i.e. return of spontaneous circulation (ROSC) or survival] and published in English 1990 or later were included, whereas animal studies, case series and reports, studies of drug administration, drug pharmacology, non-specified drug therapies, preventive drug therapy, drug administration after ROSC, studies with primarily physiological endpoints, and studies of traumatic cardiac arrest were excluded. The literature search identified a total of 8936 articles. Eighty-eight articles met our inclusion criteria and were included in the review. We identified no human study in which drug therapy, compared with placebo, improved long-term survival. Regarding adrenaline and amiodarone, the drugs currently recommended in cardiac arrest, two prospective randomized placebo-controlled trials, were identified for adrenaline, and one for amiodarone, but they were all underpowered to detect differences in survival to hospital discharge. Of all reviewed studies, only one recent prospective study demonstrated improved neurological outcome with one therapy over another using a combination of vasopressin, steroids, and adrenaline as the intervention compared with standard adrenaline administration. The evidence base for drug therapy in cardiac arrest is scarce. However, many human studies on drug therapy in cardiac arrest have not been powered to identify differences in important clinical outcomes such as survival to hospital discharge and favourable neurological outcome. Efforts are needed to initiate large multicentre prospective randomized clinical trials to evaluate both currently recommended and

    Actinomyces meyeri is an uncommon cause of actinomycosis. We present a patient with pneumonia and empyema due to A. meyeri. The patient underwent open thoracotomy with decortication and was discharged home on a twelve-month course of oral penicillin. Review of the English literature revealed thirty-two cases of infection due to A. meyeri. The majority of patients were male, and a significant number had poor dental hygiene and a history of alcoholism. More than other Actinomyces species, A. meyeri causes pulmonary infection and has a predilection for dissemination. Prognosis is favorable with prolonged penicillin therapy combined with surgical debridement, if needed.

    1986-01-01

    A sixteen year old cat was examined because of polyphagia and weight loss. On the basis of elevated thyroxine levels and the clinical presentation a diagnosis of hyperthyroidism was made. The cat was treated presurgically with propylthiouracil and propranolol. Surgical excision of the grossly affected thyroid lobe, and partial excision of the apparently normal contralateral lobe was carried out. The cat improved clinically after the surgery but elevated thyroxine levels persisted. This case and the literature review, which is presented also, stress the necessity to either demonstrate unilateral involvement via extensive presurgical work-up, or to do bilateral, or staged bilateral thyroidectomies in cases of feline hyperthyroidism.

    The purpose of this article is to present a review of literature regarding factors that influence breastfeeding intentions, initiation, and duration in the African American population. Research related to health disparities experienced by African Americans in the United States, as well as research regarding the protective benefits of breastfeeding for those specific health disparities, are also presented. Community and institutional interventions and promotional campaigns aimed at increasing initiation and duration of breastfeeding in the African American population are discussed. Future research regarding African American women's breastfeeding experiences using Black feminist thought as a theoretical foundation is recommended.

    While reviewing the available literature, we noticed comorbidity of epilepsy and psychiatric disorders. Psychiatric disorders were observed more frequently in patients with high seizure frequency. There is significant prevalence of epilepsy comorbidity with depression, anxiety disorders, and to a lesser extent with bipolar disorders and other forms of psychosis. Suicidal risk factors, ideation and attempts in these patients as correlates of depression or as psychopathological features were associated to epileptic disease. This is confirmed by additional burden of epilepsy patients with psychic disorders (Ref. 70). Full Text (Free, PDF) www.bmj.sk. PMID:19408842

    This review covers recent patent literature for fibrosis for the period 1996 to 2001. Fibrosis related-diseases remain the number one killer in the world, accounting for more than 45% of entire mortality, but there are currently no adequate therapies for most fibrotic conditions. In recent years, however, antifibrotic therapeutics have rapidly progressed following the re-investigation of existing agents that are biologically relevant to the course of fibrosis, the discovery of new targets and the reinstitution of old validated targets. The rapid progress in assay development, recombinant protein production and combinatorial chemistry has allowed more new antifibrotic agents to emerge.

    Cardiovascular disease (CVD) has become the leading cause of death for Native Americans and Alaska Natives. CVD risk factors (diabetes, hypertension, obesity, hypercholesterolemia, smoking, and sedentary lifestyle) have been studied in a number of Native American tribes, and such studies are increasing as the CVD mortality rate rises. This article reviews the literature between 1980 and 1991 concerning the prevalence of CVD risk factors in this population. In addition to summarizing the data, we describe limitations inherent in comparison and address the need for standardization of methodology in future studies. PMID:7848673

    Imaging is one of the most important tools for orthodontists to evaluate and record size and form of craniofacial structures. Orthodontists routinely use 2-dimensional (2D) static imaging techniques, but deepness of structures cannot be obtained and localized with 2D imaging. Three-dimensional (3D) imaging has been developed in the early of 1990's and has gained a precious place in dentistry, especially in orthodontics. The aims of this literature review are to summarize the current state of the 3D imaging techniques and to evaluate the applications in orthodontics. PMID:24966761

This analysis the great differences between well-knowing authors about very important subjects in occlusion, as the condylar position in centric relation and in TMJ Syndrome, or what kind of malocclusion (morphologic and functional, skeletal or dental) was the cause of TMJ Syndrome. The theory of emotional stress would be useful to explain some of the discrepancies, by reducing the occlusal disharmony to predisposal factors depending on the personal adaptation to stress.

    A 24-year-old male presented with eight months of increasingly severe frontal headaches, decreased right facial sensation, and periodic vertigo. Magnetic resonance imaging demonstrated a heterogeneously contrast-enhancing mass involving and expanding the right foramen ovale.  A biopsy of the lesion was performed, and the final pathologic diagnosis revealed a neoplastic rhabdomyoma. To date, only five cases of intracranial rhabdomyoma have been reported, and a rhabdomyoma involving the trigeminal nerve has never been described in an adult. This manuscript reviews the available literature and highlights the clinical, imaging, pathologic characteristics, and surgical management of these exceedingly rare lesions.

    An infraoptic course of the precommunicating anterior cerebral artery (A1 segment) is a rare anomaly. We report three patients with an infraoptic A1 diagnosed by computed tomography angiography and we review the literature focusing on embryological development. In all three patients, a left infraoptic A1 that originated from the ophthalmic level of the internal carotid artery was diagnosed incidentally. Only one patient had a normal supraoptic A1. The embryogenesis of this anomaly is unclear. We propose that an error in the development of the definitive ophthalmic artery is possible mechanisms giving rise to this anomaly. PMID:26914099

    The term, sacral fracture with traumatic spino-pelvic dissociation, is applied to those fractures of the sacrum in which there are both transverse and sagittal fracture lines in the sacrum, leading to a mechanical dissociation of the spine and the proximal fragment of the sacrum from the remaining sacrum and the pelvis. It is a quite rare pathological condition, and probably underdiagnosed. As it usually results from a high energy multiple trauma, an early diagnosis and treatment are mandatory for a better functional prognosis. We present a literature review of this relatively unknown injury.

    Adenocarcinoid tumour of the appendix is a rare entity characterised by the presence of a double component (neuroendocrine and glandular). It originates in the neuroendocrine cells of the appendicular mucosa. A preoperative diagnosis of a primary appendiceal tumour is uncommon and more so one suggesting an adenocarcinoid pathology. Optimal treatment is debated between a simple appendectomy and a more extensive resection, which occasionally includes hysterectomy and bilateral ovariectomy. Our aim is to report this rare entity and conduct a review of the literature on the different treatment options.

    The media play an important role in practice, policy, and public perception of child sexual abuse, in part by the way in which news stories are framed. Child sexual abuse media coverage over the past 50 years can be divided into five time periods based on the types of stories that garnered news coverage and the ways in which public policy was changed. This systematic literature review of research on child sexual abuse media coverage across disciplines and geographic boundaries examines 16 studies published in the English language from 1995 to 2012. A seminal work is identified, citation network analysis is applied, and a framework model is developed. PMID:25635896

    Objective. Primary hepatic lymphoma is a rare disease. And the clinical manifestations of this disease are nonspecific. The objective of this paper is to improve clinicians' understanding of this disease. Methods. We analyzed the clinical characteristics of a case of primary hepatic lymphoma in association with hepatitis B virus infection and reviewed the literature. Conclusion. The clinical manifestations of primary hepatic lymphoma are nonspecific. And it is easily misdiagnosed. Postoperative radiotherapy of patients with early stage was previously speculated to achieve favorable improvement. The application of targeted therapeutic drugs, chemotherapy, or combined local radiotherapy has become the first-line treatment strategy. PMID:27403354

    Pyomyositis is a pyogenic infection of skeletal muscle. Its incidence in temperate countries though low is rising. Most cases from the temperate region involve immuno-compromised patients. The onset is usually insidious with progression to large purulent collections. Because of its low incidence in temperate countries, it is often initially misdiagnosed. A high index of suspicion with appropriate imaging techniques, aggressive surgical intervention and adjunctive antibiotic therapy are the keys to prompt resolution.

When found in conjunction with other congenital abnormalities, such as cleft palate, gastrointestinal malformations, and limb malformations, this anomaly is considered part of ankyloglossia superior syndrome. We present a case of a newborn female found to have ankyloglossia superior syndrome. Surgical repair is also described. We review the available literature and discuss theories regarding the etiology of ankyloglossia superior syndrome.

    Anterior crown fractures in children and adolescents are a common form of injury, affecting approximately 25% of that population. Common restorative treatments such as composite bonding, laminate veneers, or full-coverage restorations tend to sacrifice healthy tooth structure and challenge dentists to match the adjacent unrestored dentition. Incisal edge fragment reattachment, including the use of current bonding techniques, is a restorative treatment option that offers the advantages of simplicity, immediate esthetics, and conservatism in cases of dental trauma. This article presents a comprehensive literature review on this restorative technique. It also provides diagnostic and treatment algorithms to simplify and clarify the recommended diagnostic and clinical regimens. PMID:9780892

    Background: Extradural spinal mass lesions are most commonly metastatic tumors. Extradural meningiomas are rare, accounting for approximately 2.5–3.5% of spinal meningiomas; intraoperatively, they are easily mistaken for malignant tumors, especially in the en plaque variety, resulting in inadequate surgical treatment. Case Description: Our case is one of the first to describe a patient with two purely extradural meningiomas, one each between D3–D4 and between D5–D6 vertebral levels. Surgical resection was radical, and pathologically both lesions were meningothelialmeningiomas. Conclusions: Reviewing the literature, we discuss the pathogenesis, treatment strategies, and long-term behavior of these uncommon lesions.

    Pneumocephalus or air within the cranial vault is usually associated with disruption of the skull caused by head trauma, neoplasms, or after craniofacial surgical interventions. We report a child who presented with headache and the pathognomonic "succussion splash" and was found to have atraumatic pneumocephalus from forceful valsalva maneuvers. Pneumocephalus forms, caused by either a ball-valve mechanism that allows air to enter but not exit the cranial vault, or cerebrospinal fluid (CSF) leaks, which create a negative pressure with subsequent air entry. We review the literature for traumatic and atraumatic causes of pneumocephalus, its complications, and therapy.

    The development of bioactive surgical additives to regulate the inflammation and increase the speed of healing process is one of the great challenges in clinical research. In this sense, platelet rich fibrin (PRF) appears as a natural and satisfactory alternative with favorable results and low risks. The following review attempts to summarize the relevant literature regarding the technique of using PRF, focusing on its preparation, advantages, and disadvantages of using it in clinical applications. PRF alone or in combination with other biomaterials seems to have several advantages and indications both for medicine and dentistry, due it is a minimally invasive technique with low risks and satisfactory clinical results.

    Artificial abrasion of interproximal surfaces has been described for almost seventy years as orthodontic intervention for achievement and maintenance of ideal treatment outcome. A variety of terms and approaches have been introduced throughout this period implying a growing clinicians’ interest. Nevertheless, the widespread recognition of enamel stripping technique was initiated by the advent of bonded orthodontic attachments and a 2-article series of Sheridan in the 80’s. Since then, experimental and clinical research has been focused on the investigation of instrumentation efficacy and potential iatrogenic sequelae related to interproximal stripping. This review discusses the evolution, technical aspects and trends of enamel reduction procedures as documented in the literature. PMID:24265652

    Cerebellar liponeurocytomas were recognized in the 2000 WHO 3rd edition of CNS tumors as a distinct grade I pathological entity, a tumor with a more favorable prognosis than medulloblastoma. But reports of long-term recurrences and some possible aggressive behavior led to an upgrade on the latest WHO 4th edition of CNS tumors. The case of a 64-year-old female patient is reported in this paper. More than 30 cases of this lately recognized pathological entity have been reported to date. The diagnostic, radiological, and pathological features associated with this tumor are discussed through a literature review. PMID:24716015

    Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented. PMID:25497289

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

    There has been recent widespread media coverage of events that involve murder-suicide. In this paper, the author does an extensive literature review of studies about murder-suicide. The purpose is to determine whether the incidence of murder-suicide is increasing and what its risk factors are. The results of this review show that the incidence of murder-suicide remains at under 0.001%. Risk factors for murder-suicide are based on relationship between perpetrator and victims, history of domestic violence, sex or perpetrator and victim, age of perpetrator, presence of divorce/separation, use of weapon, and history of mental illness. This paper shows that the incidence of murder-suicide is low, stable, and similar to what has been reported in the past. There are, however, some distinct risk factors for murder-suicide including: substance abuse (not as common), mostly male perpetrators, depression (more common), and older male caregivers are at risk.

    Introduction Loss of smell is involved in various neurologic and neurodegenerative diseases, such as Parkinson disease and Alzheimer disease. However, the olfactory test is usually neglected by physicians at large. Objective The aim of this study was to review the current literature about the relationship between olfactory dysfunction and neurologic and neurodegenerative diseases. Data Synthesis Twenty-seven studies were selected for analysis, and the olfactory system, olfaction, and the association between the olfactory dysfunction and dementias were reviewed. Furthermore, is described an up to date in olfaction. Conclusion Otolaryngologist should remember the importance of olfaction evaluation in daily practice. Furthermore, neurologists and physicians in general should include olfactory tests in the screening of those at higher risk of dementia. PMID:25992176

    Knowledge transfer and exchange (KTE) is as an interactive process involving the interchange of knowledge between research users and researcher producers. Despite many strategies for KTE, it is not clear which ones should be used in which contexts. This article is a review and synthesis of the KTE literature on health care policy. The review examined and summarized KTE's current evidence base for KTE. It found that about 20 percent of the studies reported on a real-world application of a KTE strategy, and fewer had been formally evaluated. At this time there is an inadequate evidence base for doing “evidence-based” KTE for health policy decision making. Either KTE must be reconceptualized, or strategies must be evaluated more rigorously to produce a richer evidence base for future activity. PMID:18070335

    The use of direct posterior resin-based composite has increased primarily due to patient esthetic desires and product improvements. Other factors (substantiated or not) contributing to increased use of resin-based composite are environmental and health concerns with dental amalgam. New visible light cured resin-based composite products are introduced yearly, as manufacturers continue to improve this tooth-colored restorative material. This paper will characterize current posterior resin-based composite materials (hybrid, microfill, flowable, and packable), review recent in vitro and clinical research, and recommend indications for these materials. In addition, the literature on compomers will be reviewed and recommendation made for their use. The data indicates that composite resin is a technique sensitive restorative material that can be used in large preparations if proper manipulation and isolation can be maintained. Compomers may also be used as an esthetic posterior restorative if proper isolation is provided.
