    Full Text Available Objective – To provide a systematic review of the emerging or newly adopted roles of information professionals, over the past 14 years, as described in the Library and Information Science (LIS professional literature. Design – Systematic review of the literature. Setting – Databases featuring information science content, including ACM Digital Library, Library, Information Science and Technology Abstracts (LISTA, Library and Information Science Abstracts (LISA, Citeseer, Google Scholar, e-prints in Library and Information Science (e-LiS, Digital Library of Information Science and Technology (DLIST, Scopus, and Science Direct. The database Library Literature & Information Science Index was not included. Subjects – Through a systematic literature search, the authors identified 114 peer-reviewed studies published between 2000-2014. Methods – The authors searched selected databases using the terms “librarian/s role” and “information professional/s role” to collect literature about the roles of information professionals. The authors searched the selected databases in two phases. The initial search yielded 600 search results and the authors included 100 articles about “roles” information professionals have adopted. The authors excluded articles focused on specific positions, health and medical libraries, librarians’ professional skills, and development of specific programs or initiatives within libraries. In the second phase of searching, the authors refined search terms to include phrases specifically related to the roles identified in the 100 articles initially included in the review. There were 48 articles identified in the second search and 14 were included in the final pool of articles. The authors also cross-checked the references of all included literature. Main Results – The authors identified six roles of information professionals described in the literature during the review period. The role of “embedded librarian

    It is imperative that the education given to United States children include adequate science taught in a way that will encourage the retention of all students; however, as half the population is female and females are underrepresented in the fields of mathematics and science, it is especially important that females be encouraged in these areas. Teacher education has been challenged to develop programs that produce teachers who understand the need for equitable science classrooms and who have the skills necessary to produce them. Several suggestions have been given for teacher education programs in science. First, college professors must examine their courses for gender bias. They must model equitable classroom strategies by planning activities that encourage the females to become active participants in the learning process and by using language that is gender inclusive. Second, definite instruction should be given to help the preservice and inservice teachers address their own attitudes toward science and children. Third, specific attention must be paid to assessing teachers in the following areas: (a) developing active, inquiry-based instruction; (b) developing classrooms in which constructive talking is the norm; (c) using cooperative groups correctly; (d) decreasing stereotyping of males, females, and scientists; and (e) using language that is gender inclusive.

  6. Current and Suggested focus on Sustainability in Pyrometallurgy

    See, J. B.; Robertson, D. G. C.; Mackey, P. J.

    The production of iron and steel and non-ferrous metals by pyrometallurgical processes will remain a critical element in meeting the demand for materials in both developed and developing nations. Given the important need to reduce and minimise greenhouse gas emissions the technological focus of future pyrometallurgical R&D by universities and industry alike must concentrate on sustainability issues such as improved energy efficiency, recycling and waste minimization. Continued efforts are also needed on process optimization and new process development with a view to reducing capital and operating costs of the new large "mega" plants. Using the academic and industrial backgrounds of the authors, the present paper reviews the current status of R&D in pyrometallurgy in university departments with a particular emphasis on sustainability issues. The role of industry and government laboratories is also reviewed although primarily for developed countries. The paper also includes comments and suggestions on the future requirements for education and R&D in pyrometallurgy in developed countries to maximise sustainability. It is also suggested that future R&D in pyrometallurgy will be even more concentrated in developing countries — most notably China.

    China has many lakes, marshlands and rivers. Due to their uneven geographical distribution and varied degrees of salinity, their exploitable freshwater resources are limited. In the wake of the highspeed growth of national economy in recent years, human infringement upon their natural settings has been increasingly intense, leading to the degeneration of China's lacustrine ecosystems and the degradation of their surrounding environments. Lakes are shrinking and becoming more saline. In arid and semi-arid inland areas, some of them have even disappeared. In addition, lake water pollution and eutrophication in densely populated areas are getting worse, resulting in serious water shortages in some places. Silt deposition in lake basins, water surface shrinkage caused by hectic and irrational reclamation for farmland, the prevalence of flooding and water-logging calamities and ecosystem depletion caused by predatory exploitation of fishery resources, all of these have become restrictive factors in regional sustainable development. The author of this article suggests measures for the protection and sustainable exploitation of limnetic settings in China.

    2016-01-01

    Vitamin A-containing products have been used topically since the early 1940s to treat various skin conditions. To date, there are four generations of retinoids, a family of Vitamin A-containing compounds. Tretinoin, all-trans-retinoic acid, is a first-generation, naturally occurring, retinoid. It is available, commercially, as a gel or cream. The authors conducted a complete review of all studies, clinical- and basic science-based studies, within the literature involving tretinoin treatment recommendations for impending facial procedures. The literature currently lacks definitive recommendations for the use of tretinoin-containing products prior to undergoing facial procedures. Tretinoin pretreatment regimens vary greatly in terms of the strength of retinoid used, the length of the pre-procedure treatment, and the ideal time to stop treatment before the procedure. Based on the current literature and personal experience, the authors set forth a set of guidelines for the use of tretinoin prior to various facial procedures.

    Full Text Available Given the varied roles Language for Specific Purposes (LSP teachers typically play and the demanding nature of LSP teaching, the literature on teacher education for LSP is surprisingly limited. This paper examines the literature on LSP teacher education including literature on teacher education in English for Specific Purposes (ESP and English for Academic Purposes (EAP. The Introduction discusses the needs of LSP teachers, whose work typically involves investigating needs and specialist discourse, developing courses and materials as well as classroom teaching. It is argued that teacher needs are an important basis for determining content for LSP teacher education programmes and that further research is needed to identify these needs. Section 2 identifies themes in the existing literature. It focuses on two themes in particular, the role of specialised knowledge and suggestions for the content of the teacher education programme. Section 3 discusses models of teacher education with particular reference to LSP in-service contexts. Section 4 identifies gaps in the literature and suggests topics for the research agenda to develop understanding of the nature of LSP teaching expertise.

    To raise some problems in the literature of acupuncture and moxibustion for treatment of peripheral facial paralysis and improving suggestions. The CHKD system was used to search out 817 papers of acupuncture for treatment of peripheral facial paralysist, which were reviewed, organized and summarized. In the literature of acupuncture for treatment of peripheral facial paralysis, insufficient understanding in the relative information of clinical data, naming of intractable facial paralysis, differentiation between of the sequelae and complications, the criteria or cproblems in the literature and so on were found. There are some common and representative problems in these papers of acupuncture for treatment of peripheral facial paralysis, which may result in incorrect opinion about the theory and clinical study of acupuncture for treatment of peripheral facial paralysis. Sufficiently considering and resolving the above problems can not only improve the quality of the papers on acupuncture for treatment of peripheral facial paralysis as a whole, but also have active influence on both treatment and diagnosis of this disease.

    There is limited knowledge on epidemiological injury data in judo. To systematically review scientific literature on the frequency and characteristics of injuries in judo. The available literature up to June 2013 was searched for prospective as well as retrospective studies on injuries in judo. Data extraction and presentation focused on the incidence rate, injury risk, types, location and causes of injuries. During the Olympic Games in 2008 and 2012, an average injury risk of about 11-12% has been observed. Sprains, strains and contusions, usually of the knee, shoulder and fingers, were the most frequently reported injuries, whereas being thrown was the most common injury mechanism. Severe injuries were quite rare and usually affected the brain and spine, whereas chronic injuries typically affected the finger joints, lower back and ears. The most common types of injuries in young judo athletes were contusions/abrasions, fractures and sprains/strains. Sex-differences data on judo injuries were mostly inconsistent. Some studies suggested a relationship between nutrition, hydration and/or weight cycling and judo injuries. Also, psychological factors may increase the risk of judo injuries. The present review provides the latest knowledge on the frequency and characteristics of injuries in judo. Comprehensive knowledge about the risk of injury during sport activity and related risk factors represents an essential basis to develop effective strategies for injury prevention. Thus, the introduction of an ongoing injury surveillance system in judo is of utmost importance.

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

    While it is evident that a surgeon must master medical knowledge and technical skill, there are other "soft skills" that are essential to a successful surgeon. One of these skills is professionalism. The challenge in surgical education lies in developing an effective professionalism curriculum and a related method of evaluation. Our review updates the literature and provides recommendations for improving instruction and evaluation of professionalism. A literature review was conducted using PubMed, Google Scholar, and Web of Knowledge. We restricted our search to documents published from 2009 to 2012 that address methods of teaching and tools for assessing professionalism in surgical education. Sixty-three documents were reviewed, with 14 fitting our search criteria for professionalism in surgical education completely. Other articles focused on the topics of professionalism in surgery, medical professionalism, and professionalism education in medical specialties other than surgery. Development of a professionalism curriculum for surgical residents might begin with defining professionalism in terms of tangible behaviors. The program might also include a precurriculum preparatory course and simulation-based training. Residency programs must also maintain professionalism among its faculty. Assessment in the form of multisource feedback that is consistent with observable behavioral definitions of professionalism should also be considered in evaluating resident professionalism.

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

    Culture is an important part in foreign language learning because no language can leave its culture contexts. Therefore, if one wants to learn a foreign language well, the acculturation is very important. But in the Chinese EFL classroom, for kinds of reasons, teachers often pay more attention to the explanation of grammatical rules and ignored the culture input which makes many Chinese students lack of pragmatic competence and can not use English in a proper way. This article will analyze the cur-rent culture teaching in our college English class and propose some suggestions.

  3. Current Levels of Salt Knowledge: A Review of the Literature

    2014-12-01

    Full Text Available High salt intake increases the risk of hypertension and cardiovascular diseases. Given the role of knowledge as a determinant of food intake, this paper aims to review the current levels of salt knowledge and the association between salt knowledge and dietary salt intake and salt-related dietary practices in the general population. Twenty two studies were included in the review. In general, the studies showed consumers were able to identify the health risks associated with high salt intake. However, knowledge of recommended daily intakes, understanding of the relationships between salt and sodium and foods that contribute most salt to the diet were poor. Four of the five studies which examined the relationships between salt knowledge and salt-related dietary practices reported significant associations. Two important gaps in the current literature were identified. First, there is a need for a robustly validated tool to examine salt knowledge and its impact on salt intake. Second, a comprehensive salt knowledge assessment should include assessment of procedural, as well as declarative, knowledge.

    2012-06-01

    To review competition injuries in taekwondo and use this information to develop recommendations to reduce the number and severity of injuries in taekwondo competition. The available literature was searched for prospective studies on taekwondo injuries in adult athletes. An injury was defined as any circumstance for which the athlete sought the assistance of the on-site medical personnel. Injury rates were expressed per athlete-exposures (A-E) and 95% CIs calculated. Total injury rates for elite men varied from 20.6/1000 A-E (95% CI 11.8 to 29.3) to 139.5/1000 A-E (95% CI 94.0 to 185.1). For elite women, the rates varied from 25.3/1000 A-E (95% CI 3.1 to 47.4) to 105.5/1000 A-E (95% CI 89.8 to 121.1). About one-third of all injuries (29.6%) in the men were to the head and neck region, while almost half of the injuries (44.5%) were to the lower extremities. In women, 15.2% of injuries were to the head and neck and 53.1% to the lower extremities. The vast majority of all injuries were contusions (42.7% in the men and 62.7% in the women). Point estimates of rates of head injuries and concussions were found to be higher in taekwondo than in other contact sports such as football (soccer) and American gridiron football. Time-loss injury rates in the men varied from 6.9/1000 A-E (95% CI 1.8 to 11.9) to 33.6/1000 A-E (95% CI 18.9 to 48.3). In the women, they varied from 2.4/1000 A-E (95% CI 2.3 to 7.2) to 23.0/1000 A-E (95% CI 15.7 to 30.4). The turning kick was most often involved in causing injury: 56.9% of all injuries in the men and 49.8% in the women. Lack of blocking skills was identified as one of the main injury mechanisms. Rule changes should be considered and it is recommended that governing bodies employ qualified medical personnel. Establishing an ongoing injury surveillance system in taekwondo should be the first priority.

  5. Current demographics suggest future energy supplies will be inadequate to slow human population growth.

    Directory of Open Access Journals (Sweden)

    John P DeLong

    Full Text Available Influential demographic projections suggest that the global human population will stabilize at about 9-10 billion people by mid-century. These projections rest on two fundamental assumptions. The first is that the energy needed to fuel development and the associated decline in fertility will keep pace with energy demand far into the future. The second is that the demographic transition is irreversible such that once countries start down the path to lower fertility they cannot reverse to higher fertility. Both of these assumptions are problematic and may have an effect on population projections. Here we examine these assumptions explicitly. Specifically, given the theoretical and empirical relation between energy-use and population growth rates, we ask how the availability of energy is likely to affect population growth through 2050. Using a cross-country data set, we show that human population growth rates are negatively related to per-capita energy consumption, with zero growth occurring at ∼13 kW, suggesting that the global human population will stop growing only if individuals have access to this amount of power. Further, we find that current projected future energy supply rates are far below the supply needed to fuel a global demographic transition to zero growth, suggesting that the predicted leveling-off of the global population by mid-century is unlikely to occur, in the absence of a transition to an alternative energy source. Direct consideration of the energetic constraints underlying the demographic transition results in a qualitatively different population projection than produced when the energetic constraints are ignored. We suggest that energetic constraints be incorporated into future population projections.

    Goracci, C; Ferrari, M

    2011-06-01

    This literature review summarizes the most recent and reliable evidence on post systems. A search was limited to review articles published over the last 10 years in dental journals with an impact factor. Papers cited in the initially retrieved review articles were also included if significant. Preservation of tooth tissue, presence of a ferrule effect, and adhesion are regarded as the most effective conditions for long-term success of post-endodontic restorations. Adhesively luted fibre-reinforced composite post restorations have demonstrated satisfactory survival rates over relatively long follow-up periods. The clinical effectiveness of such restorations has been mainly ascribed to the more biomimetic behaviour of fibre-reinforced composite posts that reduces the risk of vertical root fractures. The most common type of failure when using fibre posts is post debonding and it is generally agreed that achieving stable adhesion to intraradicular dentine is more challenging than to coronal dentine. Several factors related to endodontic treatment, root canal shape, post space preparation, post translucency, adhesive cement handling and curing may have an influence on the outcome of the luting procedure. The most reliable results in fibre post cementation are obtained by etch-and-rinse adhesives in combination with dual-cure resin cements. The use of self-adhesive resin cements has also been proposed. Simplification is an obvious advantage of these new materials. However, the durability of their bond still needs to be verified with long-term clinical studies. Several techniques for pre-treating the fibre-reinforced composite post surface have been tested with the aim of improving the bond strength at the post-core and post-cement interfaces. Silicoating followed by silanization currently appears to be the most effective and convenient method for this purpose. In conclusion, the available evidence validates the use of fibre posts as an alternative to metal posts and

    2015-04-01

    A flare ribbon is the chromospheric image of reconnection at a coronal current sheet. The dynamics and structure of the ribbon can thus reveal properties of the current sheet, including motion of the reconnecting flare loops. We present imaging and spectroscopic observations from the Interface Region Imaging Spectrograph (IRIS) of the evolution of a flare ribbon at high spatial resolution and time cadence. These reveal small-scale substructure in the ribbon, which manifest as oscillations in both position and Doppler velocities. We consider various alternative explanations for these oscillations, including modulation of chromospheric evaporation flows. Among these we find the best support for some form of elliptical wave localized to the coronal current sheet, such as a tearing mode or Kelvin-Helmholtz instability.IRIS is a NASA Small Explorer mission developed and operated by Lockheed Martin Solar and Astrophysics Laboratory. This work is supported by contract 8100002702 from Lockheed Martin to Montana State University, a Montana Space Grant Consortium fellowship, and by NASA through HSR.

    2017-08-01

    Full Text Available A great variety of non-specific symptoms may occur in patients living or working in moisture-damaged buildings. In the beginning, these symptoms are usually reversible, mild, and present irritation of mucosa and increased morbidity due to respiratory tract infections and asthma-like symptoms. Later, the disease may become chronic and a patient is referred to a doctor where the assessment of dampness and mold hypersensitivity syndrome (DMHS often presents diagnostic challenges. Currently, unanimously accepted laboratory tests are not yet available. Therefore, the diagnosis of DMHS is clinical and is based on the patient’s history and careful examination. In this publication, I reviewed contemporary knowledge on clinical presentations, laboratory methods, and clinical assessment of DMHS. From the literature, I have not found any proposed diagnostic clinical criteria. Therefore, I propose five clinical criteria to diagnose DMHS: (1 the history of mold exposure in water-damaged buildings, (2 increased morbidity to due infections, (3 sick building syndrome, (4 multiple chemical sensitivity, and (5 enhanced scent sensitivity. If all the five criteria are met, the patient has a very probable DMHS. To resolve the current problems in assigning correct DMHS diagnosis, we also need novel assays to estimate potential risks of developing DMHS.

  15. Current aspects of polycystic ovary syndrome: A literature review

    Directory of Open Access Journals (Sweden)

    VICTOR HUGO LOPES DE ANDRADE

    Full Text Available SUMMARY Polycystic ovary syndrome (PCOS is a heterogeneous endocrine disorder with variable prevalence, affecting about one in every 15 women worldwide. The diagnosis of polycystic ovary syndrome requires at least two of the following criteria: oligoovulation and/or anovulation, clinical and/or biochemical evidence of hyperandrogenism and morphology of polycystic ovaries. Women with PCOS appear to have a higher risk of developing metabolic disorders, hypertension and cardiovascular disorders. The aim of this article was to present a review of the literature by searching the databases Pubmed and Scielo, focusing on publications related to polycystic ovaries, including its pathogenesis, clinical manifestations, diagnosis and therapeutic aspects, as well as its association with cardiovascular and arterial hypertensive disorders.

    Cuzzi, J. N.

    1978-01-01

    The state of our current knowledge of the properties of the ring system as a whole, and of the particles individually, is assessed. Attention is primarily devoted to recent results and possibilities for exploration of the ring system by a Saturn orbiter. In particular, the infrared and microwave properties of the ring system are discussed. The behavior of the ring brightness is not well understood in the critical transition spectral region from approximately 100 micrometers to approximately 1 cm. Also, the dynamical behavior of the ring system is discussed. Recent theoretical studies show that ongoing dynamical effects continually affect the ring structure in azimuth (possibly producing the A ring brightness asymmetry) and in the vertical direction. Orbital spacecraft-based studies of the rings will offer several unique advantages and impact important cosmogonical questions. Bistatic radar studies and millimeter-wavelength spectrometer/radiometry will give particle sizes and composition limits needed to resolve the question of the density of the rings, and provide important boundary conditions on the state of Saturn's protoplanetary nebula near the time of planetary formation.

    Candidiasis or oral candidosis is one of the most common human opportunistic fungal infections of the oral cavity. This pathology has a wide variety of treatment which has been studied until these days. The present study offers a literature review on the treatment of oral candidiasis, with the purpose of establish which treatment is the most suitable in each case. Searching the 24 latest articles about treatment of candidiasis it concluded that the incidence depends on the type of the candidiasis and the virulence of the infection. Although nystatin and amphotericin b were the most drugs used locally, fluconazole oral suspension is proving to be a very effective drug in the treatment of oral candidiasis. Fluconazole was found to be the drug of choice as a systemic treatment of oral candidiasis. Due to its good antifungal properties, its high acceptance of the patient and its efficacy compared with other antifungal drugs. But this drug is not always effective, so we need to evaluate and distinguish others like itraconazole or ketoconazole, in that cases when Candida strains resist to fluconazole. Key words:Candidiasis, treatment, miconazole, fluconazole, nystatin.

  18. Mechanisms and Kinetics of Environmentally Assisted Cracking: Current Status, Issues, and Suggestions for Further Work

    Lynch, S. P.

    2013-03-01

    Mechanisms and kinetics of metal-induced embrittlement, hydrogen-embrittlement, and stress-corrosion cracking are discussed, and long-standing controversies are addressed by reviewing critical observations. Recommendations are also made regarding further work (including repetition of previous work using more advanced measurement and characterisation techniques) that should be carried out in order to resolve some of the contentious issues. The evidence to date suggests that adsorption-based mechanisms, involving weakening of substrate interatomic bonds so that dislocation emission or decohesion is facilitated, accounts for embrittlement in many systems. Embrittling adsorbed species include some metal atoms, hydrogen, and complex ions produced by de-alloying. Other viable mechanisms of embrittlement include those based on (1) dissolution of anodic grain-boundary regions, and (2) decohesion at grain boundaries owing to segregated hydrogen and impurities. The hydrogen-enhanced localised-plasticity mechanism, based on solute hydrogen facilitating dislocation activity in the plastic zone ahead of cracks, makes a contribution in some cases, but is relatively unimportant compared with these other mechanisms for most fracture modes. The film-induced cleavage mechanism, proposed especially for stress-corrosion cracking in systems involving de-alloying at crack tips, is questionable on numerous grounds, and is probably not viable. Rate-controlling processes for environmentally assisted cracking are not well established, except for solid-metal induced embrittlement where surface self-diffusion of embrittling atoms to crack tips controls cracking kinetics. In some systems, adsorption kinetics are probably rate-controlling for liquid-metal embrittlement, hydrogen-environment embrittlement, and stress-corrosion cracking. In other cases, rate-controlling processes could include the rate of anodic or cathodic reactions at and behind crack tips (responsible for producing embrittling

HBV infection is a potentially life threatening condition as many of the affected individuals progress to chronic hepatitis,cirrhosis and hepatocellular carcinoma (HCC(3. In infants and children, acute hepatitis B infection is nearly always asymptomatic, whereas in adults it is usually the opposite. But on the other hand, the risk of becoming chronic carriage is much greater in children than in adults; as many as 90% of infants born to Hepatitis B e Antigen (HBeAg positive mothers become carriers themselves and, therefore, in long term are more likely to developchronic liver disease(5. Currently, though several antiviral drugs are used,there is no reliable curative treatment for HBV once it has been acquired and prevention by universal immunization remains the strategy for reducing the number of acute infections, chronic carriage and the long-term burden from diseases such as HCC(4,6. In 1991, in an attempt to reduce the global impact of HBV infection, WHO recommended that hepatitis B vaccination should be integrated into national immunization programs in all countries(7.Some Asian countries, for instance, Thailand, haveadopted the policy of immunizing children universally against the disease as early as 1992, however many others lagged behind(4.The true prevalence of Hepatitis B in Bangladesh is yet to be ascertained by a reliable study. Data available from different studies show that it ranges between 0.8 and 5.4% depending on the study design, samples and laboratory methods used(8-10.These data were based on detection of HBsAg antigen; the rates would have been higher, had they been based on anti-HBc antibody(11

    This paper presents current data on the pathophysiology of gestational diabetes mellitus, classification and new diagnostic methods. Gestational Diabetes Mellitus (GDM) is defined as carbohydrate intolerance first detected during pregnancy. It is the most common metabolic disorder of pregnant women. The frequency of its occurrence depends on inter alia body weight, belonging to a particular ethnic group and diagnostic methods. GDM reveals usually between 24 and 28 weeks of gestation. The development of diabetes in pregnancy poses a threat to both the mother and the fetus. It is associated with an increased incidence of birth defects in newborns, impaired intrauterine fetal growth, higher incidence of premature births and greater percentage of the intrauterine fetus death. Amongst women complicated by gestational diabetes arterial hypertension more often unfolds. In the development of gestational diabetes mellitus important role apart from maternal and fetal hyperinsulinemia play: antagonistic to insulin placental hormones, TNFα, placental pro-inflammatory cytokines, resistin, leptin ghrelin.

    2015-01-01

    Hepatocellular carcinoma (HCC) is the fifth mostcommon form of human cancer worldwide and the thirdmost common cause of cancer-related deaths. Thestrategies of various treatments for HCC depend onthe stage of tumor, the status of patient's performanceand the reserved hepatic function. The Barcelona ClinicLiver Cancer (BCLC) staging system is currently usedmost for patients with HCC. For example, for patientswith BCLC stage 0 (very early stage) and stage A (earlystage) HCC, the curable treatment modalities, includingresection, transplantation and radiofrequency ablation,are taken into consideration. If the patients are in BCLCstage B (intermediate stage) and stage C (advancedstage) HCC, they may need the palliative transarterialchemoembolization and even the target medicationof sorafenib. In addition, symptomatic treatment isalways recommended for patients with BCLC stage D(end stage) HCC. In this review, we will attempt tosummarize the historical perspective and the currentdevelopments of systemic therapies in BCLC stage Band C in HCC.

    Full Text Available Craniocerebral gunshot injuries (CGI are increasingly encountered by neurosurgeons in civilian and urban settings. Unfortunately, more prevalent condition in developing countries, with major armed conflicts which is still persisting, since the main trigger is violence at the national or state level. Management goals of CGI should focus on aggressive resuscitation and correction of coagulopathy; those with stable vital signs should undergo CT scan head at the earliest possible opportunity. Neuroimaging is vital for planning of surgical management, especially to determine the type of surgery, routes of the approach to the surgical target area and extraction of the impacted foreign bodies, however, surgical management is not always indicated. Although subset of such cases may be managed even with non-surgical management. The treatment comprises of immediate life salvaging resuscitative measures including control of the persistent bleeding, care of associated injury, management of raised intracranial pressure, prevention of cerebrospinal fistula formation by primary watertight dural repair and prevention of infection, through extensive debridement of contaminated, macerated or ischemic tissues; preservation of nervous tissue and restoration of anatomic structures through the hermetic sealing of dural and scalp defect. Recently, only few studies of craniocerebral penetrating injuries are published that too involving smaller patients sample sizes; although classic studies in the military and civil situation noticed associated relatively very high mortality and morbidity and psychological as well as economic impact on the affected individual, the family and the health system in providing ongoing care to the sufferers and society at large. Currently various measures are advocated with aim to reduce the incidence of CGI especially in civilian populations. It is highly necessary and immensely urgent to promote research in a neurocritical care of CGI to

    Aim: To identify current practices within paediatric radiology in the UK with regard to the use of prophylactic medication, prior to administering intravenous (IV) radiocontrast medium (RCM). In addition, the pre-injection risk management strategies of the departments questioned was to be evaluated, and using consensus opinion, a protocol for managing patients identified as being at high risk for an adverse reaction to RCM was to be outlined. Materials and methods: An online survey of paediatric radiology consultants representing all geographic regions of the UK was carried out. The questions asked included an assessment of the risk factors for adverse reactions to RCM, and how such reactions are anticipated and managed. The questionnaire asked about the perceived indications for, and the use of prophylactic medication prior to RCM administration. Results: A response rate of 51% was achieved. The majority of respondents felt that a history of previous RCM reaction was an indication to administer prophylactic drugs prior to a further dose of RCM. No other risk factor was believed to require prophylactic medication. Conclusion: Using information obtained from the survey, a literature search was performed to assess the evidence available in support of each practice. A protocol was devised to identify children at risk of an adverse reaction to RCM, and guide the use of prophylactic medication in this group of patients. The survey highlighted considerable variability in the risk-assessment and management practices within paediatric radiology in the UK. The derived protocol may guide radiologists' management of children at risk for an RCM reaction.

    2015-01-01

    Medicinal marijuana has already been legalized in over 23 states with more considering legalization. Despite the trend toward legalization, to date, there has been no systematic review of the existing literature for the efficacy of medicinal marijuana for many of the conditions for which it is proposed to treat. This study seeks to understand the current literature regarding the use of medicinal marijuana in the treatment of posttraumatic stress disorder (PTSD). PubMed and PsycINFO databases were searched until April 2014 for articles outlining outcomes of case files, control studies, and observational studies regarding the efficacy of medicinal marijuana in treating PTSD. Various combinations of the following search terms were used: marijuana, medicinal marijuana, cannabis, cannabinoid, PTSD, efficacy, trial, and neurobiology. Full text of each article was reviewed, and those directly addressing the question of efficacy of medicinal marijuana on PTSD symptomatology were included. Data were extracted from a total of 46 articles. Analysis revealed that most reports are correlational and observational in basis with a notable lack of randomized, controlled studies. Many of the published studies suggest a decrease in PTSD symptoms with marijuana use. Though the directionality of cannabis use and PTSD could not be fully differentiated at this time, there appears to also be a correlation between PTSD and problematic cannabis use. Despite this finding, there is a growing amount of neurobiological evidence and animal studies suggesting potential neurologically based reasons for the reported efficacy. Posttraumatic stress disorder is 1 of the approved conditions for medicinal marijuana in some states. While the literature to date is suggestive of a potential decrease in PTSD symptomatology with the use of medicinal marijuana, there is a notable lack of large-scale trials, making any final conclusions difficult to confirm at this time.

    Demand for health care service has significantly increased, while the quality of healthcare and patient safety has become national and international priorities. This paper aims to identify the gaps and the current initiatives for optimizing the quality of care and patient safety in Malaysia. Review of the current literature. Highly cited articles were used as the basis to retrieve and review the current initiatives for optimizing the quality of care and patient safety. The country health plan of Ministry of Health (MOH) Malaysia and the MOH Malaysia Annual Reports were reviewed. The MOH has set four strategies for optimizing quality and sustaining quality of life. The 10th Malaysia Health Plan promotes the theme "1 Care for 1 Malaysia" in order to sustain the quality of care. Despite of these efforts, the total number of complaints received by the medico-legal section of the MOH Malaysia is increasing. The current global initiatives indicted that quality performance generally belong to three main categories: patient; staffing; and working environment related factors. There is no single intervention for optimizing quality of care to maintain patient safety. Multidimensional efforts and interventions are recommended in order to optimize the quality of care and patient safety in Malaysia.

    Our objective was to audit our current stress ulcer prophylaxis protocol (routine prescription of ranitidine and early enteral feeding) by identifying whether routine prescription of histamine-2 receptor antagonists or proton pump inhibitors as prophylaxis against stress-related mucosal disease and subsequent upper gastrointestinal bleeding is supported in the literature. We also aimed to ascertain what literature evidence supports the role of early enteral feeding as an adjunctive prophylactic therapy, as well as to search for burn-patient specific evidence, since burn patients are at high risk for developing this condition, with the aim of changing our practice. PubMed and Cochrane databases were searched for relevant articles, yielding seven randomised controlled trials comparing histamine-2 receptor antagonists and proton pump inhibitors in the prevention of upper gastrointestinal bleeding associated with stress-related mucosal disease and three separate meta-analyses. Despite level 1 clinical evidence, no significant difference in efficacy between histamine-2 receptor antagonists and proton pump inhibitor treatment groups was demonstrated. No significant difference was demonstrated in the incidence of nosocomial pneumonia between the two drugs given in this indication. However, enteral feeding was found to be safe and effective in preventing clinically significant upper gastrointestinal bleeding. Patients able to tolerate feeds demonstrated no additional benefit with concomitant pharmacological prophylactic therapy. Since all burn patients at the Royal Adelaide Hospital are fed from very early in their admission, the literature suggests that we, like our intensive care unit colleagues, should abolish our reliance on pharmacological prophylaxis, the routine prescription of which is not supported by the evidence.

    2015-01-01

    The purpose of the literature review was to assess the origins of radiology physician extenders and examine the current roles found in the literature of advanced practice physician extenders within medical imaging. Twenty-six articles relating to physician assistants (PAs), nurse practitioners (NPs), radiologist assistants (RAs), and nuclear medicine advanced associates (NMAAs) were reviewed to discern similarities and differences in history, scope of practice, and roles in the medical imaging field. The literature showed PAs and NPs are working mostly in interventional radiology. PAs, NPs, and RAs perform similar tasks in radiology, including history and physicals, evaluation and management, preprocedure work-up, obtaining informed consent, initial observations/reports, and post-procedure follow-up. NPs and PAs perform a variety of procedures but most commonly vascular access, paracentesis, and thoracentesis. RAs perform gastrointestinal, genitourinary, nonvascular invasive fluoroscopy procedures, and vascular access procedures. The review revealed NMAAs are working in an advanced role, but no specific performances of procedures was found in the literature, only suggested tasks and clinical competencies. PAs, NPs, and RAs are currently the three main midlevel providers used in medical imaging. These midlevel providers are being used in a variety of ways to increase the efficiency of the radiologist and provide diagnostic and therapeutic radiologic procedures to patients. NMAAs are being used in medical imaging but little literature is available on current roles in clinical practice. More research is needed to assess the exact procedures and duties being performed by these medical imaging physician extenders.

    In recent years there has been increased interest in the role of commercial soft drinks in dental diseases namely as dental caries and erosion. The objective of this paper has been to review the past and current literature to determine the present knowledge on this subject. The literature related to dental caries, erosion, drinks, soft drinks and fruit juices was reviewed. The literature shows efforts have been taken to modify soft drinks by either adding or deleting certain components so as to reduce their harmful effects on teeth. A rational protocol to encourage the sensible use of drinks and the modification of drinks to render them less harmful would be advisable.

    Malignant hair follicle tumors are rare skin adnexal malignancies that have a predilection for the head and neck region. They can be categorized into a number of different subtypes. Histologically, they are distinct from their benign counterpart. To the best of our knowledge, there is no extensive review of these malignancies, especially in the periorbital region. We aim to provide a literature review and a guideline for management of these malignant tumors in the periorbital region. Database from Medline, PubMed, Embase, and Google Scholar were consulted. A total of 16 cases from the literature on hair follicle malignancies in the periorbital region were included in this review. The clinical presentations, diagnostic patterns, investigations used, and best management approach of these tumors are discussed. The American Joint Committee on Cancer (AJCC) 7(th) edition carcinoma of the eyelid staging system was used to describe their behaviors. We recommend wide excision surgery and a close follow-up for these tumors. Tumors presenting with a late stage require work-up for distant metastasis and consideration for exenteration procedures. The role of radiotherapy and chemotherapy in this context is still uncertain.

    2014-11-01

    The literature on the efficacy and safety of rufinamide in childhood-onset epilepsy syndromes currently includes approximately 600 paediatric patients. This paper summarizes the views of a panel of experienced European epileptologists with regard to the current role of rufinamide in the treatment of childhood epilepsies. Rufinamide is effective in decreasing the seizure frequency in the Lennox-Gastaut syndrome (LGS), especially tonic and atonic seizures. It might consequently be preferred to other drugs as a second-line treatment for LGS when drop-attacks are frequent. The mean responder rate in the published studies is 38% with seizure freedom achieved in 2.4% of patients. Rufinamide has shown some efficacy in epileptic encephalopathies other than LGS. It can be also effective as adjunctive therapy in children and adolescents with drug-resistant partial seizures. The available data suggest that rufinamide has an acceptable risk/benefit ratio with quite a low risk of aggravating seizures. Common adverse effects (somnolence, nausea and vomiting) are usually mild and self-limiting; they are more frequently observed during titration than in the maintenance phase, suggesting that low escalation rates might be associated with fewer adverse effects. Rufinamide appears to have a favourable cognitive profile compared with other antiepileptic drugs. Rufinamide is only approved for adjunctive treatment of seizures associated with LGS in children 4 years of age and older. There are very few data on rufinamide treatment at the onset of LGS or early in the course of the disorder; whether early treatment will improve outcome has yet to be determined.

    Full Text Available Business incubators (BIs are a significant tool in promoting the development of entrepreneurial firms, technology-based growth firms and economic growth in South Africa. The study reviewed the current literature on business incubation in South Africa. BIs in South Africa emerged as a popular strategy in the 1990s and most of the current literature was established in the same period. However, the current literature is still limited. The aim of this paper is to provide an overview of existing knowledge on the role and effectiveness of business incubation in supporting the development of new small startup businesses. The quantitative and qualitative literature published by the academic and practitioner communities is reviewed. The searches indicated that incubation has encouraged many studies in South Africa. The studies can be categorised under the following themes: the role and contribution of incubators, success factors for business incubation, obstacles, and the relationship between incubators and entrepreneurship. The areas for further research are suggested. Two major areas that new research can explore focus on the creation of the model and selfsustainability of BIs.

    2011-10-01

    Full Text Available The rewetting of dry soils and the thawing of frozen soils are short-term, transitional phenomena in terms of hydrology and the thermodynamics of soil systems. The impact of these short-term phenomena on larger scale ecosystem fluxes has only recently been fully appreciated, and a growing number of studies show that these events affect various biogeochemical processes including fluxes of soil gases such as carbon dioxide (CO2, methane (CH4, nitrous oxide (N2O, ammonia (NH3 and nitric oxide (NO. Global climate models predict that future climatic change is likely to alter the frequency and intensity of drying-rewetting events and thawing of frozen soils, highlighting the importance of understanding how rewetting and thawing will influence soil gas fluxes. Here we summarize findings in a new database based on 338 studies conducted from 1956 to 2010, and highlight open research questions. The database revealed conflicting results following rewetting and thawing in various terrestrial ecosystems, ranging from large increases in gas fluxes to non-significant changes. An analysis of published field studies (n = 142 showed that after rewetting or thawing, CO2, CH4, N2O, NO and NH3 fluxes increase from pre-event fluxes following a power function, with no significant differenced among gases. We discuss possible mechanisms and controls that regulate flux responses, and note that a high temporal resolution of flux measurements is critical to capture rapid changes in gas fluxes after these soil perturbations. Finally, we propose that future studies should investigate the interactions between biological (i.e. microbial community and gas production and physical (i.e. flux, diffusion, dissolution changes in soil gas fluxes, and explore synergistic experimental and modelling approaches.

    Seminal vesicles (SVs) are sex accessory organs and part of male genitourinary system. They play a critical role in male fertility. Diseases of the SVs, usually results in infertility. Diseases of the SVs are extremely rare and are infrequently reported in the literature. We address the current literature of SV pathologies, symptoms, diagnosis, and treatment options. We review the clinical importance of SVs from PubMed. The current imaging modalities and instrumentation that help diagnose SV diseases are reviewed. Common pathologies including, infection, cysts, tumors, and congenital diseases of the SVs are addressed. Many times symptoms of hematospermia, pain, irritative and obstructive lower urinary tract symptoms, and infertility are presented in patients with SV diseases.

    Full Text Available One of the fundamental issues in American forest policy has been the small forest ownership problem. Early in the twentieth century, it was called the farm forestry problem, later, the nonindustrial private forest problem, and today, the family forest problem. Family forest owners are thought to manage their lands in a suboptimal manner resulting in low forest productivity relative to other ownership groups. This can lead to future timber supply problems. The exact nature of the problem, especially its social and economic basis, was a common subject of early forestry research studies. This article includes many of the major nonindustrial private forest or family forest studies, from early to current, and classifies them both by themes used by other authors and categories that relate to major research areas in the current literature. A major focus of this literature deals with promoting management on family forest holdings and possible land management incentives and disincentives. Natural trends in family forest ownership, like parcelization, also impact upon forest management opportunities. By developing a taxonomy that classifies these studies by research objective, methodology, owner motivation, and problem definition, this article serves to organize the family forest literature in a manner that provides a temporal framework for better understanding the historical motivation for and development of family forest research in the United States.

    Ulcerative colitis(UC) is one of the main types of inflammatory bowel disease, which is caused by dysregulated immune responses in genetically predisposed individuals. Several genetic factors, including interleukin and interleukin receptor gene polymorphisms and other inflammation-related genes play central role in mediating and modulating the inflammation in the human body, thereby these can be the main cause of development of the disease. It is clear these data are very important for understanding the base of the disease, especially in terms of clinical utility and validity, but summarized literature is exiguous for challenge health specialist that can used in the clinical practice nowadays. This review summarizes the current literature on inflammationrelated genetic polymorphisms which are associated with UC. We performed an electronic search of Pubmed Database among publications of the last 10 years, using the following medical subject heading terms: UC, ulcerative colitis, inflammation, genes, polymorphisms, and susceptibility.

    Medication error (ME) is the most common single preventable cause of adverse drug events which negatively affects patient safety. ME prevalence is a valuable safety indicator in healthcare system. Inadequate studies on ME, shortage of high-quality studies and wide variations in estimations from developing countries including Iran, decreases the reliability of ME evaluations. In order to clarify the status of MEs, we aimed to review current available literature on this subject from Iran. We searched Scopus, Web of Science, PubMed, CINAHL, EBSCOHOST and also Persian databases (IranMedex, and SID) up to October 2012 to find studies on adults and children about prescription, transcription, dispensing, and administration errors. Two authors independently selected and one of them reviewed and extracted data for types, definitions and severity of MEs. The results were classified based on different stages of drug delivery process. Eighteen articles (11 Persian and 7 English) were included in our review. All study designs were cross-sectional and conducted in hospital settings. Nursing staff and students were the most frequent populations under observation (12 studies; 66.7%). Most of studies did not report the overall frequency of MEs aside from ME types. Most of studies (15; 83.3%) reported prevalence of administration errors between 14.3%-70.0%. Prescribing error prevalence ranged from 29.8%-47.8%. The prevalence of dispensing and transcribing errors were from 11.3%-33.6% and 10.0%-51.8% respectively. We did not find any follow up or repeated studies. Only three studies reported findings on severity of MEs. The most reported types of and the highest percentages for any type of ME in Iran were administration errors. Studying ME in Iran is a new area considering the duration and number of publications. Wide ranges of estimations for MEs in different stages may be because of the poor quality of studies with diversity in definitions, methods, and populations. For gaining

    Ictal headaches are increasingly becoming the focus of research as more data demonstrate headaches existing as a sole manifestation of an epileptic event. Due to the difficulty in diagnosing the event as an epileptic phenomenon as opposed to a migraine, the condition is often misdiagnosed. This paper seeks to review the current published literature on ictal epileptic headaches as well as provide differentiation between ictal headaches and similarly presenting conditions. In doing so, we hope to improve the diagnosis of ictal headaches and thus improve patient care. We review two case studies that exemplify the potential of multiple conditions with comparable symptoms to ictal headaches, and discuss how to differentiate the variable diagnoses. As of the writing of this paper, there is no universally agreed upon set of features of ictal headaches; however, reviewing the current literature, there do seem to be several features that should be noted when treating patients. More research on the pathophysiology of ictal epileptic headaches needs to be done before the condition can be fully understood.

    Full Text Available The volumetric intensity modulated arc therapy (VMAT is a novel radiation technique that delivers a highly conformal radiation dose to the target by allowing the simultaneous variation of gantry rotation speed, dose rate and multiple-leaf collimators leaf positions. The aim of this study was to review the current literature on two VMAT systems, RapidArc and SmartArc with main focus on planning studies of lung cancer. A systematic review of available data was conducted using MEDLINE/PubMed with the keywords ′′lung′′ and "VMAT". The published data show that VMAT techniques have clear superiority over three-dimensional conformal radiation therapy with regard to improving dose conformity and sparing of organs at risks (OARs. The data indicates that for lung tumor VMAT and intensity modulated radiation therapy (IMRT provide equivalent dose homogeneity, dose conformity and target volume coverage; however, contradictory results were obtained in terms of OARs sparing. The major advantages of VMAT over IMRT are the reduction in the number of monitor units and faster treatment delivery times without compromising the quality of the treatment plans. Moreover, faster delivery time is more patient-friendly and it minimizes intra-fractional patient motion allowing treatment volumes stay within their respective treatment margins. Current literature data shows that VMAT can be a good option to treat lung cancer; however, data on clinical trials are still lacking. The clinical trials are essential to confirm the safety and efficacy of VMAT techniques.

    Full Text Available Aim: To visit the operative technique and to review the current published English literature on the technique, and outcomes following robot-assisted laparoscopic partial nephrectomy (RPN. Materials and Methods: We searched the published English literature and the PubMed (TM for published series of ′robotic partial nephrectomy′ (RPN using the keywords; robot, robot-assisted laparoscopic partial nephrectomy, laparoscopic partial nephrectomy, partial nephrectomy and laparoscopic surgery. Results: The search yielded 15 major selected series of ′robotic partial nephrectomy′; these were reviewed, tracked and analysed in order to determine the current status and role of RPN in the management of early renal neoplasm(s, as a minimally invasive surgical alternative to open partial nephrectomy. A review of the initial peri-operative outcome of the 350 cases of select series of RPN reported in published English literature revealed a mean operating time, warm ischemia time, estimated blood loss and hospital stay, of 191 minutes, 25 minutes, 162 ml and 2.95 days, respectively. The overall computed mean complication rate of RPN in the present select series was about 7.4%. Conclusions: RPN is a safe, feasible and effective minimally invasive surgical alternative to laparoscopic partial nephrectomy for early stage (T 1 renal neoplasm(s. It has acceptable initial renal functional outcomes without the increased risk of major complications in experienced hands. Prospective randomised, controlled, comparative clinical trials with laparoscopic partial nephrectomy (LPN are the need of the day. While the initial oncological outcomes of RPN appear to be favourable, long-term data is awaited.

    Patients treated with oral anticoagulant therapy (OAT) represent an issue to the dentist, as an increasing number of people are using anticoagulant drugs for cardiovascular disease. The choice of an eventual suspension or continuation of anticoagulant therapy is important when considering an efficient management of the patient. Patients in anticoagulant therapy and requiring dental procedures sometimes represent therapeutic concerns especially concerning the suspension of the anticoagulant treatment. At the moment there is no consensus among international experts of a possible discontinuation of therapy before invasive dental procedures. In this paper, the authors try to focus on this topic through a critical review of the literature. Most of the studies suggest the continuation of the anticoagulant treatment with heparin before invasive oral surgical interventions. Based on the data of the literature, two rules must be adopted in clinical practice: 1) maintenance of anticoagulation related to the international normalized ratio (INR); 2) local application of antifibrinolytic agents to ensure a proper hemostatic process. Given the widespread use of anticoagulant drugs in cardiovascular disease, dentists must often face the problem of the therapy and, since there is no consensus on the management of these patients, the authors propose, after a thorough critical review of the literature, the implementation of a multiphase protocol of surgical approach to be implemented with safety in daily clinical practice.

    Full Text Available Background. Recent literature has associated hepatitis C virus with the development of non-Hodgkin lymphoma. Hepatitis C virus infection appears to promote lymphoproliferation, providing a plausible mechanism for a causative association; however, despite prior reports of patients with comorbid hepatitis C infection and Waldenström macroglobulinemia, the literature is in disagreement regarding whether there exists an association between these two conditions. Case Presentation. This case report describes a 57-year-old African-American male with chronic hepatitis C infection and cryoglobulinemia who presented with several episodes of transient confusion and paralysis and was found to have symptomatic hyperviscosity. The recognition of his condition was facilitated by characteristic findings on ophthalmologic examination. He was subsequently diagnosed with Waldenström macroglobulinemia on bone marrow biopsy. Conclusions. An up to date, comprehensive review of the literature suggests an association between hepatitis C and Waldenström macroglobulinemia. Data on optimal treatment of patients with comorbid hepatitis C infection and Waldenström macroglobulinemia is limited. We have provided a comprehensive review of previously explored treatment options to guide management of other similar patients. Our patient has since been treated with repeated plasmapheresis with a plan to pursue antiviral therapy.

  10. Design and array signal suggestion of array type pulsed eddy current probe for health monitoring of metal tubes

    An array type probe for monitoring metal tubes is proposed in this paper which utilizes peak value and peak time of a pulsed eddy current(PEC) signal. The probe consists of an array of encircling coils along a tube and the outside of coils is shielded by ferrite to prevent source magnetic fields from directly affecting sensor signals since it is the magnetic fields produced by eddy currents that reflect the condition of metal tubes. The positions of both exciter and sensor coils are consecutively moved automatically so that manual scanning is not necessary. At one position of send-receive coils, peak value and peak time are extracted from a sensor PEC signal and these data are accumulated for all positions to form an array type peak value signal and an array type peak time signal. Numerical simulation was performed using the backward difference method in time and the finite element method for spatial analysis. Simulation results showed that peak value increases and the peak appears earlier as the defect depth or length increases. The proposed array signals are shown to be excellent in reflecting the defect location as well as variations of defect depth and length within the array probe.

    The National Assembly of Lao People's Democratic Republic (Laos) approved the Health Sector Reform Strategy in 2012, which called for an assessment as to whether Laos should introduce hospital autonomy, and if so, in which ways. The purpose of this study is to assess the status quo of hospital governance in Laos and propose policy suggestions for hospital autonomy in the country. We formulated an analytic framework for hospital autonomy based on previous work by other researchers, collected qualitative data through key informant interviews and focus group discussions, and also performed secondary data analysis. Public hospitals in Laos enjoyed some informal autonomy with little accountability and Laos is facing key challenges of hospital governance. As a result, introducing hospital autonomy in Laos could bring risks, benefits and debates. Before Laos decides on granting autonomy to its public hospitals, we strongly suggest that the government do pilot in selected public hospitals with well-regulated governance framework first and conduct rigorous evaluations to examine whether the granted autonomy leads to the intended social goals of equity, quality, efficiency and sustainability. We recommend residual claimants should be monitored by the government and by the society with open and transparent approach, and active measures should be taken to improve performance and ensure social functions. The study findings may also provide some suggestions for low- and middle-income countries, which are contemplating the introduction of hospital autonomy in the public sector.

    2012-02-01

    Much of the literature describing the search for agents that increase the life span of rodents was found to suffer from confounds. One-hundred-six studies, absent 20 contradictory melatonin studies, of compounds or combinations of compounds were reviewed. Only six studies reported both life span extension and food consumption data, thereby excluding the potential effects of caloric restriction. Six other studies reported life span extension without a change in body weight. However, weight can be an unreliable surrogate measure of caloric consumption. Twenty studies reported that food consumption or weight was unchanged, but it was unclear whether these data were anecdotal or systematic. Twenty-nine reported extended life span likely due to induced caloric restriction. Thirty-six studies reported no effect on life span, and three a decrease. The remaining studies suffer from more serious confounds. Though still widely cited, studies showing life span extension using short-lived or "enfeebled" rodents have not been shown to predict longevity effects in long-lived animals. We suggest improvements in experimental design that will enhance the reliability of the rodent life span literature. First, animals should receive measured quantities of food and its consumption monitored, preferably daily, and reported. Weights should be measured regularly and reported. Second, a genetically heterogeneous, long-lived rodent should be utilized. Third, chemically defined diets should be used. Fourth, a positive control (e.g., a calorically restricted group) is highly desirable. Fifth, drug dosages should be chosen based on surrogate endpoints or accepted cross-species scaling factors. These procedures should improve the reliability of the scientific literature and accelerate the identification of longevity and health span-enhancing agents.

    Nanoparticles are entering natural systems through product usage, industrial waste and post-consumer material degradation. As the production of nanoparticles is expected to increase in the next decade, so too are predicted environmental loads. Engineered metal-oxide nanomaterials, such as titanium dioxide, are known for their photocatalytic capabilities. When these nanoparticles are exposed to ultraviolet radiation in the environment, however, they can produce radicals that are harmful to aquatic organisms. There have been a number of studies that have reported the toxicity of titanium dioxide nanoparticles in the absence of light. An increasing number of studies are assessing the interactive effects of nanoparticles and ultraviolet light. However, most of these studies neglect environmentally-relevant experimental conditions. For example, researchers are using nanoparticle concentrations and light intensities that are too high for natural systems, and are ignoring water constituents that can alter the light field. The purpose of this review is to summarize the current knowledge of the photocatalytic effects of TiO2 nanoparticles on aquatic organisms, discuss the limitations of these studies, and outline environmentally-relevant factors that need to be considered in future experiments.

    2014-11-01

    Full Text Available This article considers selected drivers of decision variability in child welfare decision-making and explores current debates in relation to these drivers. Covering the related influences of national orientation, risk and responsibility, inequality and poverty, evidence-based practice, constructions of abuse and its causes, domestic violence and cognitive processes, it discusses the literature in regards to how each of these influences decision variability. It situates these debates in relation to the ethical issue of variability and the equity issues that variability raises. I propose that despite the ecological complexity that drives decision variability, that improving internal (within-country decision consistency is still a valid goal. It may be that the use of annotated case examples, kind learning systems, and continued commitments to the social justice issues of inequality and individualisation can contribute to this goal.

    2014-10-01

    Pediculosis capitis is the most common ectoparasitic disease in children in industrialized countries and extremely common in resource-poor communities of the developing world. The extensive use of pediculicides with a neurotoxic mode of action has led to the development and spread of resistant head lice populations all over the world. This triggered the development of compounds with other modes of action. The current literature on treatment approaches of head lice infestation was searched, and published randomized controlled trials were critically analyzed. The following compounds/family of compounds were identified: spinosad, a novel compound with a new neurotoxic mode of action, isopropyl myristate, 1,2-octanediol, ivermectin, plant-based products, and dimeticones. The efficacy and safety of these compounds are reviewed and recommendations for the treatment of pediculosis capitis in individuals as well as the interruption of ongoing epidemics are provided.

    Full Text Available The paper describes a 44-year-old male patient with an about 6-year history of hypertrophic pachymeningitis. The major clinical symptoms were characterized by headache, exophthalmos, and blindness in one eye. The data for differential diagnosis of the disease are given. The current literature on the clinical manifestations of hypertrophic pachymeningitis, its differential diagnosis, and the results of magnetic resonance imaging (MRI is reviewed. Diagnostic difficulties at the stage of a clinical observation are due to the nonspecificity of neurological manifestations and the need for a comprehensive examination to detect a somatic disease. MRI can diagnose the disease-specific phenomenon of damage to the meninges, which calls for further careful differentiation. Clinicians must be familiar with alternative differential diagnosis, as a rapid specific therapeutic approach will help avoid long-term or irreversible neurological complications.

    2015-10-01

    Accreditation Council for Graduate Medical Education guidelines require internal medicine residents to develop skills in the interpretation of medical literature and to understand the principles of research. A necessary component is the ability to understand the statistical methods used and their results, material that is not an in-depth focus of most medical school curricula and residency programs. Given the breadth and depth of the current medical literature and an increasing emphasis on complex, sophisticated statistical analyses, the statistical foundation and education necessary for residents are uncertain. We reviewed the statistical methods and terms used in 49 articles discussed at the journal club in the Department of Internal Medicine residency program at Texas Tech University between January 1, 2013 and June 30, 2013. We collected information on the study type and on the statistical methods used for summarizing and comparing samples, determining the relations between independent variables and dependent variables, and estimating models. We then identified the typical statistics education level at which each term or method is learned. A total of 14 articles came from the Journal of the American Medical Association Internal Medicine, 11 from the New England Journal of Medicine, 6 from the Annals of Internal Medicine, 5 from the Journal of the American Medical Association, and 13 from other journals. Twenty reported randomized controlled trials. Summary statistics included mean values (39 articles), category counts (38), and medians (28). Group comparisons were based on t tests (14 articles), χ2 tests (21), and nonparametric ranking tests (10). The relations between dependent and independent variables were analyzed with simple regression (6 articles), multivariate regression (11), and logistic regression (8). Nine studies reported odds ratios with 95% confidence intervals, and seven analyzed test performance using sensitivity and specificity calculations

    Sports participation can be an integral part of adolescent development with numerous positive short and long-term effects. Despite these potential benefits very high levels of physical activity, during skeletal maturation, have been proposed as a possible cause of cam-type femoroacetabular impingement (FAI). The influence of physical activity on the developing physis has been previously described both in animal studies and epidemiological studies of adolescent athletes. It is therefore important to determine whether the development of FAI is secondary to excessive physical activity or a combination of a vulnerable physis and a set level of physical activity. A review of the current literature suggests that adolescent males participating in ice-hockey, basketball and soccer, training at least three times a week, are at greater risk than their non-athletic counterparts of developing the femoral head-neck deformity associated with femoroacetabular impingement.

Generic medicines provide the same therapeutic outcomes but at a much cheaper cost, so are promoted in many countries to contain pharmaceutical expenditure and sustain the health care system. Thus, the perspective of patients and medicine consumers as end users of these medicines is an important factor to enhance the use and utilization of generic medicines. The objective of this paper is to review patients’ and consumers’ knowledge, perceptions, acceptance, and views of generic medicines in the current literature. Methods: An extensive literature search was performed in several databases, namely Scopus, PubMed, ISI Web of Knowledge, Proquest, and the Wiley online library, to identify relevant studies published in the English literature for the period 1990–2013. Results: A total of 53 studies were included in the review, comprising 24 studies from Europe, ten from North America, six from Asia, five from Australia and New Zealand, five from the Middle East, one from Africa, one from Latin America, and one from the Caribbean region. A large body of literature has reported misconceptions and negative perceptions about generic medicines on the part of patients and medicine consumers.

    There is a general agreement that a patient in labor should be given the option to have an epidural block for pain management. Despite this consensus, there are differences in practice patterns as to when to initiate an epidural and how to minimize its impact on the duration and outcome of a patient's labor. A review of the literature suggests epidural analgesia does prolong stages one and two of labor, but not significantly. Cesarean delivery rates are not affected by the early initiation of epidural analgesia. The use of various adjuvants such as opioids, clonidine, and neostigmine in conjunction with local anesthetics solution can significantly reduce the severity of motor blockade and the need for assisted vaginal delivery.

    Full Text Available The present study aims to review current thinking and understanding of the issue of Intercultural Communicative Competence (ICC especially in foreign language education contexts. There are serious stances on the part of scholars in foreign language contexts, which must be given some serious thinking and consideration in order to uncover the hidden agendas regarding ICC. After all, it seems still unclear in English as a Foreign Language (EFL contexts whether to try to improve the way of thinking regarding the perspective of current intercultural communicative competence, whether there should be a separation of the cultural values from the target language and only integrate language learners’ native culture with the target language. Given the development of technology and globalization, what is the right thing to do? This is a serious issue which needs much attention and contemplation by the interested scholars. By presenting the existing gaps in the literature, the paper maneuvers on the challenging notes on benefiting from culture in English Language Teaching (ELT and, on the other hand, dividing language and culture by merely elaborating on the communicative aspect of language learning and teaching. The study puts the audience into question that although recent views are focusing on taking English as an international means of communication, there exist serious beliefs regarding the separation of language and culture, which demands more thinking and probably serious revisions.

    Interest in mindfulness has increased exponentially, particularly in the fields of psychology and medicine. The trait or state of mindfulness is significantly related to several indicators of psychological health, and mindfulness-based therapies are effective at preventing and treating many chronic diseases. Interest in mobile applications for health promotion and disease self-management is also growing. Despite the explosion of interest, research on both the design and potential uses of mindfulness-based mobile applications (MBMAs) is scarce. Our main objective was to study the features and functionalities of current MBMAs and compare them to current evidence-based literature in the health and clinical setting. We searched online vendor markets, scientific journal databases, and grey literature related to MBMAs. We included mobile applications that featured a mindfulness-based component related to training or daily practice of mindfulness techniques. We excluded opinion-based articles from the literature. The literature search resulted in 11 eligible matches, two of which completely met our selection criteria-a pilot study designed to evaluate the feasibility of a MBMA to train the practice of "walking meditation," and an exploratory study of an application consisting of mood reporting scales and mindfulness-based mobile therapies. The online market search eventually analyzed 50 available MBMAs. Of these, 8% (4/50) did not work, thus we only gathered information about language, downloads, or prices. The most common operating system was Android. Of the analyzed apps, 30% (15/50) have both a free and paid version. MBMAs were devoted to daily meditation practice (27/46, 59%), mindfulness training (6/46, 13%), assessments or tests (5/46, 11%), attention focus (4/46, 9%), and mixed objectives (4/46, 9%). We found 108 different resources, of which the most used were reminders, alarms, or bells (21/108, 19.4%), statistics tools (17/108, 15.7%), audio tracks (15/108, 13

    2015-10-01

    The number of publications about myofascial pain and trigger points (TrP) seems to increase every year. In the current overview we include 27 articles published in past months. The Basic Review section includes articles about the presence and characteristics of TrPs in various neck and shoulder muscles, the correlation between referred pain from active TrPs and knee osteoarthritis, and an anatomical study exploring whether the location of TrPs may be related to the nerve innervation of muscles. Zuil-Escobar and colleagues from Spain considered the intra-rater reliability of the identification of latent TrPs in several leg muscles and the possible correlation of TrP and the presence of a lower medial longitudinal arch. In the section on manual approaches, contributing author Rob Grieve and colleagues continue their studies of TrPs in the lower extremity muscles, while Méndez-Rebolledo and colleagues studied the impact of cross taping and compression. Dry needling (DN) continues to be a topic of interest. We included twelve papers addressing a wide range of topics, such as the effectiveness and safety of DN, and the impact of DN on proprioception, spasticity, and fibromyalgia. Two papers investigated the utilization of repetitive transcranial magnetic stimulation and laser on TrPs, The final section on other clinical studies and reviews includes 8 papers. The studies originated in thirteen different countries with Spain leading the charts with 7 contributions to the literature, followed by Brazil with four. As we have mentioned in previous editions of this literature overview, many studies suffer from very small sample sizes, which makes it difficult to reach definitive conclusions. Nevertheless, myofascial pain continues to be a topic of interest to researchers and clinicians around the globe. Copyright © 2015 Elsevier Ltd. All rights reserved.

    As a result of widespread screening and treatment programs, the incidence of cervical cancer has decreased by as much as 75% in the developed world. Commonly used treatment modalities for precancerous lesions include cone biopsy, the Loop Electrosurgical Excision Procedure (LEEP), laser ablation and cryotherapy. In recent years LEEP has replaced cryotherapy as a commonly provided outpatient procedure in many places; however increased awareness of the burden of cervical cancer in the developing world and increased awareness of long term consequences of LEEP ‑ such as cervical insufficiency ‑ have renewed interest in cryotherapy. We reviewed current literature addressing the technique, efficacy, safety and acceptability of cryotherapy, as well as special topics such as cost effectiveness, HIV, and low resource settings. Among studies we reviewed, cure rates ranged from 56.8-96.6% among prospective controlled trials and from 70-95.5% among observational studies. Cryotherapy has very low complication rates and serious complications requiring medical intervention or affecting future reproductive outcomes are extremely rare. Side effects including vaginal discharge and cramping are temporary, generally self-limited, and well tolerated after anticipatory patient counseling. When surveyed, women find cryotherapy highly acceptable. Compared to other treatment modalities, cryotherapy is very affordable and feasible to integrate into cervical cancer screening and treatment programs.

    With the advent of enhanced depth imaging optical coherence tomography (EDI-OCT), detailed visualisation of the choroid in vivo is now possible. Measurements of choroidal thickness (CT) have also enabled new directions in research to study normal and pathological processes within the choroid. The aim of the present study is to review the current literature on choroidal imaging using EDI-OCT. Studies were identified by a systematic search using Medline ( http://www.ncbi.nlm.nih.gov/pubmed ). Papers were also identified based on the reference lists of relevant publications. Papers were included in the review if the focus of the study involved imaging of the choroid using EDI-OCT. Recent studies have demonstrated successful imaging of the choroid and high reproducibility of measurements of CT using EDI-OCT. There are much data confirming that abnormalities in choroidal structure and function contribute to major ocular diseases and patterns of CT variation may be observed in certain disease states and may be influenced by treatment. However, it is not clear whether these variations are a contributing factor or a consequence of the disease. While more invasive methods such as indocyanine green (ICG) angiography remain the gold standard for detecting abnormalities of the choroidal vasculature in normal eyes and disease states, EDI-OCT has become an important adjunctive clinical tool in providing three-dimensional anatomical information of the choroid.

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

The frequency is increased in polyostotic forms, McCune–Albright syndrome, Mazabraud’s syndrome, and previously irradiated sites. Rapidly progressing pain unrelated to trauma is the most concerning symptom. The early radiological features of sarcomatous transformation are moth-eaten or cystic areas of osteolysis, cortical destruction, and gradual formation of a soft tissue mass. The prognosis is unfavorable as most of the cases are in an advanced stage at the time of diagnosis.Methods: This case was diagnosed at a large cancer center in Florida. Pertinent clinical findings were obtained from chart review and inter-departmental consultation.Results: Histopathological examination revealed dysplastic lamellar bone with no osteoblastic rimming and “Chinese letter” shapes, areas composed of lobulated hyaline cartilage with mild to severe nuclear atypia, and areas of poorly differentiated cells with a spindled appearance, consistent with chondrosarcoma arising within fibrous dysplasia.Conclusions: Sarcomatous transformation of fibrous dysplasia is an uncommon occurrence, yet has significant importance for those with the disease. There may be difficulty with diagnosis given the symptoms and radiologic findings of benign fibrous dysplasia. We report a case of chondrosarcoma rising in fibrous dysplasia and review the current literature. This case is of interest due to the fact that the diagnosis of monostotic fibrous dysplasia was first made at the age of 59 and

    Objective To describe the interactions between drugs and nutrients and their frequency in the intensive care unit and to assess the professional team's awareness regarding this subject. Methods The keywords "drug interactions" and "nutrition therapy" were searched in the PubMed (specifically MeSH) electronic database. The studies were systematically reviewed for descriptions of the types of interactions between drugs and nutrients, including their frequency and consequences. Results Sixty-seven articles were found. Among these, 20 articles were appropriate for the methodology adopted and accomplished the objectives of the study. Of these 20 articles, 14 articles described interactions between drugs and enteral nutrition, three described interactions between drugs and parenteral nutrition, and three described the importance and care required to avoid such interactions. Conclusions The literature about drug and nutrient interactions is limited and suggests the inability of health care teams to recognize the potential for these interactions. Possibly, the elaboration of a protocol to evaluate drug-nutrient interactions will increase the safety and efficacy of therapeutics. PMID:23917982

    The 2009 Global Platform for Disaster Risk Reduction/Emergency Preparedness (DRR/EP) and the Hyogo Framework for Action 2005-2015 demonstrate increased international commitment to DRR/EP in addition to response and recovery. In addition, the World Health Report 2008 has re-focused the world's attention on the renewal of Primary Health Care (PHC) as a set of values/principles for all sectors. Evidence suggests that access to comprehensive PHC improves health outcomes and an integrated PHC approach may improve health in low income countries (LICs). Strong PHC health systems can provide stronger health emergency management, which reinforce each other for healthier communities. The global re-emphasis of PHC recently necessitates the health sector and the broader disaster community to consider health emergency management from the perspective of PHC. How PHC is being described in the literature related to disasters and the quality of this literature is reviewed. Identifying which topics/lessons learned are being published helps to identify key lessons learned, gaps and future directions. Fourteen major scientific and grey literature databases searched. Primary Health Care or Primary Care coupled with the term disaster was searched (title or abstract). The 2009 ISDR definition of disaster and the 1978 World Health Organization definition of Primary Health Care were used. 119 articles resulted. Literature characteristics; 16% research papers, only 29% target LICs, 8% of authors were from LICs, 7% clearly defined PHC, 50% used PHC to denote care provided by clinicians and 4% cited PHC values and principles. Most topics related to disaster response. Key topics; true need for PHC, mental health, chronic disease, models of PHC, importance of PHC soon after a natural disaster relative to acute care, methods of surge capacity, utilization patterns in recovery, access to vulnerable populations, rebuilding with the PHC approach and using current PHC infrastructure to build

    It is currently believed that autoimmune conditions are triggered and aggravated by a variety of environmental factors such as cigarette smoking, infections, ultraviolet light or chemicals, as well as certain medications and vaccines in genetically susceptible individuals. Recent scientific data have suggested a relevant role of these factors not only in systemic lupus erythematosus, but also in cutaneous lupus erythematosus (CLE). A variety of environmental factors have been proposed as initiators and exacerbators of this disease. In this review we focused on those with the most convincing evidence, emphasizing the role of drugs in CLE. Using a combined search strategy of the MEDLINE and CINAHL databases the following trigger factors and/or exacerbators of CLE have been identified and described: drugs, smoking, neoplasms, ultraviolet radiation and radiotherapy. In order to give a practical insight we emphasized the role of drugs from various groups and classes in CLE. We also aimed to present a short clinical profile of patients with lesions induced by various drug classes.

    Modern standards for evidence-based decision making in clinical care and public health still rely solely on eminence-based input when it comes to normative ethical considerations. Manuals for clinical guideline development or health technology assessment (HTA) do not explain how to search, analyze, and synthesize relevant normative information in a systematic and transparent manner. In the scientific literature, however, systematic or semi-systematic reviews of ethics literature already exist, and scholarly debate on their opportunities and limitations has recently bloomed. A systematic review was performed of all existing systematic or semi-systematic reviews for normative ethics literature on medical topics. The study further assessed how these reviews report on their methods for search, selection, analysis, and synthesis of ethics literature. We identified 84 reviews published between 1997 and 2015 in 65 different journals and demonstrated an increasing publication rate for this type of review. While most reviews reported on different aspects of search and selection methods, reporting was much less explicit for aspects of analysis and synthesis methods: 31 % did not fulfill any criteria related to the reporting of analysis methods; for example, only 25 % of the reviews reported the ethical approach needed to analyze and synthesize normative information. While reviews of ethics literature are increasingly published, their reporting quality for analysis and synthesis of normative information should be improved. Guiding questions are: What was the applied ethical approach and technical procedure for identifying and extracting the relevant normative information units? What method and procedure was employed for synthesizing normative information? Experts and stakeholders from bioethics, HTA, guideline development, health care professionals, and patient organizations should work together to further develop this area of evidence-based health care.

    The importance of transparency with financial ties in biomedical research is widely recognized, and most peer-reviewed journals require declarations of Conflicts of Interest (COI). Nonetheless, variability in the consistency of declarations of COI has been sparsely assessed. To assess consistency and rates of COI declarations in the ophthalmic literature and the effectiveness of journal COI policies. We analyzed consistency and completeness of declaration of COI in the ophthalmic literature and compared the levels of completeness to specific journal requirements. Six-hundred forty-two peer reviewed articles satisfied the inclusion criteria. In 64%, COIs were unreported, in 25% declaration of COI was incomplete, and 11% of the articles reviewed had complete declaration of COI. Of the 33 journals in which the most frequently published authors' articles appeared, 10 required the authors to complete the International Committee of Medical Journal Editors (ICMJE) form or an equivalent form, but this did not affect the rates of COI declaration. In a random sampling of the most frequently published authors in the field of ophthalmology, declaration of COI was low and highly inconsistent. Requiring a standardized COI form has no significant effect on the rate of accurate COI reporting. Our findings lend support to the growing body of literature that shows that journals and editors may need to take a more active role in ensuring accurate and consistent COI reporting.

    The objective was to evaluate deficits and differences of published literature on reproduction in cattle, horses, and dogs. A literature search was conducted in the databases Medline and Veterinary Science. Approximately five times more articles on clinical bovine reproduction (n = 25 910) were found compared to canine (n = 5 015) and equine (n = 5 090) reproduction. For the evaluation of the literature, a checklist was used. A subset of 600 articles published between 1999 and 2008 was randomly selected. After applying exclusion criteria, a total of 268 trials (86 for cattle, 99 for horses, and 83 for dogs) were evaluated and used for further analysis. For the field of canine and equine reproduction, there were fewer clinical trials with a control group compared to bovine reproduction (cattle 66%, horses 41%, and dogs 41%). For all three species investigated, few publications were identified (4%) with the highest level of evidence, i.e., controlled, randomized, and blinded trials, or meta-analyses. In cattle 33% of the publications were graded adequate to draw sound conclusions; however, only 7 and 11% were graded adequate in dogs and horses, respectively. Therefore, the veterinarian should always assess the quality of information before implementing results into practice to provide best available care for the animals. In conclusion, improvement of the quality of well-designed, conducted and reported clinical trails in animal reproduction is required.

    While rheumatologists often focus on treatment targets, for many patients with rheumatoid arthritis (RA), control over pain and fatigue, as well as sustaining physical function and quality of life (QoL), is of primary importance. This literature review aimed at examining patients' and physicians' treatment aspirations, and identifying the unmet needs for patients with RA receiving ongoing treatment. Searches were performed using MEDLINE, Embase, PsycINFO, and Econlit literature databases for articles published from 2004 to 2014 in the English language. Published literature was screened to identify articles reporting the unmet needs in RA. We found that, despite the wide range of available treatments, RA continues to pose a substantial humanistic and economic burden on patients, and there are still unmet needs across key domains such as pain, physical function, mental function, and fatigue. These findings suggest that there is a need for further treatment advances in RA that address these domains of contemporary unmet need.

    Objetive The main objective of this systematic literature review is to identify the safest and most effective sedative drugs so as to ensure successful sedation with as few complications as possible. Study Design A systematic literature review of the PubMed MEDLINE database was carried out using the key words “conscious sedation,” “drugs,” and “dentistry.” A total of 1,827 scientific articles were found, and these were narrowed down to 473 articles after applying inclusion and exclusion criteria. These 473 studies were then individually assessed for their suitability for inclusion in this literature review. Results A total of 21 studies were selected due to their rigorous study design and conduciveness to further, more exhaustive analysis. The selected studies included a total of 1,0003 patients classified as ASA I or II. Midazolam was the drug most frequently used for successful sedation in dental surgical procedures. Ketamine also proved very useful when administered intranasally, although some side effects were observed when delivered via other routes of administration. Both propofol and nitrous oxide (N2O) are also effective sedative drugs. Conclusions Midazolam is the drug most commonly used to induce moderate sedation in dental surgical procedures, and it is also very safe. Other sedative drugs like ketamine, dexmedetomidine and propofol have also been proven safe and effective; however, further comparative clinical studies are needed to better demonstrate which of these are the safest and most effective. Key words:Conscious sedation, drugs, dentistry. PMID:27475684

    Vulvar cancer is a relatively rare gynecologic malignancy with an annual incidence in developed countries of approximately 2 per 100,000 women. Vulvar squamous cell carcinoma (VSCC) has two etiological pathways: a high risk human papillomavirus (HPV)-dependent route, which has usual vulvar intraepithelial neoplasia (uVIN) as a precursor lesion, and an HPV-independent route, which is associated with differentiated VIN (dVIN), lichen sclerosus, and genetic alterations, such as TP53 mutations. Research on the molecular etiology of vulvar cancer has increased in the past years, not only regarding genetic alterations, but also epigenetic changes. In genetic alterations, a mutation irreversibly changes the nucleotide sequence of the DNA, or the number of copies of chromosomes per cell is altered. In epigenetics, the nucleotide sequence remains the same but genes can be 'switched' on or off by, for example, DNA methylation or histone modification. We searched the current literature on genetic and epigenetic alterations in VSCC and its precursor lesions. Many studies have reported a higher incidence of somatic mutations in HPV-negative tumors compared to HPV-positive tumors, with TP53 mutations being the most frequent. Allelic imbalances or loss of heterozygosity are more frequently found in higher stages of dysplasia and in invasive carcinomas, but it is not exclusive to HPV-negative tumors. A limited number of studies are available on epigenetic changes in vulvar lesions, with hypermethylation of CDKN2A being the most frequently investigated change. For most genes, hypermethylation occurs more frequently in vulvar squamous cell carcinomas than in precursor lesions. As most studies have focused on HPV infection and TP53 mutations, we suggest that more research should be performed using whole genome or next generation sequencing to determine the true landscape of genetic and epigenetic alterations in vulvar squamous cell carcinoma.

    A comparative study was conducted in this work in order to investigate the current situation in the Nile river basin (NRB) regarding the institutional and legal arrangements needed to support the adaptive integrated water resources management (AIWRM) strategy. Two similar river basins were selected to achieve this comparison and to introduce suggestions to reform the current situation in the basin. Before that, the ideal situation is investigated to be as a yardstick for the desired situation. The study indicated that the necessary AIWRM criteria may include regulatory as well as implementation organizations that support shared-vision reaching with its all necessary features (cooperation, stakeholders' participation, subsidiarity, and information and knowledge exchange). Thus the main features of the desired situations regarding AIWRM in river basins are stakeholders' participation, learning-driven ability, quick response to risks and uncertainties, and finally a legal framework that could support these criteria. Although the AIWRM criteria seem to be satisfied in NRB, the basin lacks the necessary regulatory institutions as well as the legal framework. According to this, this study recommends to reform the current situation in NRB by creating regulator institutions (policy and decision making level) as well a legal framework to legitimate them.

    Head trauma is a major medical, social, economic, national, and public health priority issue in the United States. In severe head trauma, the overwhelming clinical manifestations are so compelling that damage to the visual system is most likely to be ignored. Both the afferent and efferent visual systems are susceptible to injury after head trauma, and physicians should be aware of the visual system and perform a thorough neuro-ophthalmic evaluation in patients presenting with head trauma.Most of the data available on neuro-ophthalmic complications of head trauma including cortical blindness, Horner's syndrome, traumatic internuclear ophthalmoplegia, and ocular motor palsy, comes from case reports highlighting the need for future studies to better understand these complications.This review summarizes some of the most important neuro-ophthalmic complications of head trauma including cortical blindness, Horner's syndrome, traumatic internuclear ophthalmoplegia, and ocular motor palsy. Search of the peer-reviewed literature was conducted using MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Global Health, and MD Consult.

    2015-05-22

    Clinical dental work is placing increasing demands on a clinician's vision as new techniques that require fine detail become more common. High hand-eye coordination requires good visual acuity as well as other psychological and neurological qualities such as stereopsis. Stereopsis (three-dimensional vision) is the highest form of depth perception obtained by visual disparity of images formed in the retinas of two eyes. It is believed to confer functional benefits on everyday tasks such as hand-eye coordination. Although its role in depth perception has long been established, little is known regarding the importance of stereopsis in dentistry. This article reviews the role of stereopsis in everyday life and the available literature on the importance of stereopsis in dentistry.

    Fill, Ted S; Carey, Jason P; Toogood, Roger W; Major, Paul W

    2011-01-01

    Introduction. This review is intended to highlight and discuss discrepancies in the literature of the periodontal ligament's (PDL) mechanical properties and the various experimental approaches used to measure them. Methods. Searches were performed on biomechanical and orthodontic publications (in databases: Compendex, EMBASE, MEDLINE, PubMed, ScienceDirect, and Scopus). Results. The review revealed that significant variations exist, some on the order of six orders of magnitude, in the PDL's elastic constants and mechanical properties. Possible explanations may be attributable to different experimental approaches and assumptions. Conclusions. The discrepancies highlight the need for further research into PDL properties under various clinical and experimental loading conditions. Better understanding of the PDL's biomechanical behavior under physiologic and traumatic loading conditions might enhance the understanding of the PDL's biologic reaction in health and disease. Providing a greater insight into the response of the PDL would be instrumental to orthodontists and engineers for designing more predictable, and therefore more efficacious, orthodontic appliances.

    Newbound, D R; O'Shea, J E

    2001-01-01

    A comprehensive anatomical study was undertaken to examine the rectal salt gland in the Port Jackson shark, Heterodontus portusjacksoni, a shark known to invade estuarine environments. The microstructure and vascular organisation of the rectal salt gland was investigated using histological observation and scanning electron microscopy of vascular corrosion casts. Cellular specialisation was observed in the lining of the central lumen of this gland. This may indicate that there is some modification of the principal product of the gland prior to its secretion. The rectal salt gland has a complex structure related to its function. Contrary to previous reports, the flow in secretory tubules is in the opposite direction to that of the capillaries and thus constitutes a counter-current arrangement. The similarity in the organisation of the counter-current and lobulate arrangement of salt-secreting glands through phylogenetically diverse organisms, such as sharks and birds, suggests that this arrangement is important in achieving efficient salt secretion.

    Heart lung transplantation is a viable treatment option for patients with many end-stage heart and lung pathologies. However, given the complex nature of the procedure, it is imperative that patients are selected appropriately, and the clinician is aware of the many unique aspects in management of this population. This review seeks to describe updated organ selection policies, perioperative and postoperative management strategies, monitoring of graft function, and clinical outcomes for patients after combined heart-lung transplantation in the current era.

    Balancing selection has been widely assumed to be an important evolutionary force, yet even today little is known about its abundance and its impact on the patterns of genetic diversity. Several studies have shown examples of balancing selection in humans, plants or parasites, and many genes under balancing selection are involved in immunity. It has been proposed that host-parasite coevolution is one of the main forces driving immune genes to evolve under balancing selection. In this paper, we review the literature on balancing selection on immunity genes in several organisms, including Drosophila. Furthermore, we performed a genome scan for balancing selection in an African population of Drosophila melanogaster using coalescent simulations of a demographic model with and without selection. We find very few genes under balancing selection and only one novel candidate gene related to immunity. Finally, we discuss the possible causes of the low number of genes under balancing selection.

    2016-07-01

    Full Text Available Colchicine, extracted from the colchicum autumnale plant, used by the ancient Greeks more than 20 centuries ago, is one of the most ancient drugs still prescribed even today. The major mechanism of action is binding to microtubules thereby interfering with mitosis and subsequent modulation of polymorphonuclear leukocyte function. Colchicine has long been of interest in the treatment of cardiovascular disease; however, its efficacy and safety profile for specific conditions have been variably established in the literature. In the subset of pericardial diseases, colchicine has been shown to be effective in recurrent pericarditis and post-pericardiotomy syndrome (PPS. The future course of treatment and management will therefore highly depend on the results of the ongoing large randomized placebo-controlled clinical trial to evaluate the efficacy and safety of colchicine for the primary prevention of several postoperative complications and in the perioperative period. Also, given the positive preliminary outcomes of colchicine usage in pericardial effusions, the future therapeutical use of colchicine looks promising. Further study is needed to clarify its role in these disease states, as well as explore other its role in other cardiovascular conditions.

    The worldwide interest in myofascial pain syndrome (MPS) and trigger points (TrPs) is reflected in the increasing number of publications. In this overview of the literature, we included 26 studies, case reports and review articles by authors from 18 different countries. Several research groups are exploring the characteristic of TrPs such as Chen and colleagues, who continued their work on the quantification of the taut bands. Meng and colleagues studied the relationships between TrPs and central sensitization, while Yu and colleagues examined the electrophysiological characteristics that occur as a result of active TrPs. Several researchers used objective measurements to determine clinical outcomes, such as Koppenhaver and colleagues who measured objective changes in the function and nociceptive sensitivity of lumbar multifidus muscle subjects with low back pain. Turo and colleagues quantified muscle tissue changes after dry needling in chronic myofascial pain using elastography. Multiple studies explored various treatment options for TrPs, such as dry needling, injections with lidocaine or granisetron, traditional Thai massage, self-myofascial release, kinesiotaping, and monochromatic infrared photo energy, among others.

  9. Current State of Development of Electricity-Generating Technologies: A Literature Review

    Full Text Available Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as large—especially rural—segments of the world population in developing countries start to climb the “energy ladder” and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a low-carbon world economy.

    Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semirigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS). We enrolled experienced endourologists (more than 75 cases/year in the last 3 years) and we performed a survey asking to review their series and report the cases encumbered by major complications (Clavien-Dindo IIIb-IV grade). Eleven urologists reported on 12 major complications (4 after s-URS, 8 after f-URS). Eight patients developed a kidney injury, 1 an arteriovenous fistula, 2 a ureter avulsion and 1 acute sepsis. Six patients underwent open nephrectomy, two surgical repair, one open pyeloplasty, one coil artery embolization and two superselective artery embolization. Guidelines and clinical practice give useful recommendations about intraoperative safety and prevention of life-threatening events. The careful postoperative observation and the surgical active treatment of this complications play a key role in reducing morbidity, kidney loss and mortality. This study encourages a strict and active care of patients, supports a routine reporting of complications, and highlights the need for systematic use of standardized classification systems.

    Distinguishing malignant versus benign lymphadenopathies is a major diagnostic dilemma in clinical medicine. Metastatic deposits in normal-sized lymph nodes (LNs) can be smaller than a millimeter, thus presenting a diagnostic challenge. In most clinical settings, however, enlarged LNs detected on imaging need to be classified as malignant or benign. Ultrasound seems to be a very reliable method for LN characterization because of the high resolution, especially in the subcutaneous areas. However, B-mode and Doppler-ultrasound criteria for characterization of a lymphadenopathy as benign or malignant are lacking specificity. Newer methods such as elastography seem to be valuable for identifying metastatic deposits within LNs and may help discriminate malignant and benign LNs. This review summarizes the different elastographic methods available and provides an overview of the relevant publications. According to the literature, elastography can be used for identifying metastatic deposits, to guide fine needle aspiration and to non-invasively choose the most suspicious LN of a group of enlarged LNs for targeted biopsy.

    Currently, the only standardized evaluation of trauma knowledge throughout orthopedic training is found in the Orthopaedic In-Training Examination, which is administered annually to all residents by the American Academy of Orthopaedic Surgeons. Our goals were to assess the Orthopaedic In-Training Examination to (1) determine the content of the trauma questions, (2) identify the content of the 3 most frequently referenced journals on the answer keys, and (3) evaluate the correlation between those contents.We reviewed the trauma-related Orthopaedic In-Training Examination questions and answer keys for 2002 through 2007. Content for test questions and cited literature was assessed with the same criteria: (1) category type, (2) anatomic location, (3) orthopedic focus, and (4) treatment type. For each of the 3 most frequently referenced journals, we weighted content by dividing the number of times it was referenced by the number of its trauma-related articles. We then compared the journal data individually and collectively to the data from the Orthopaedic In-Training Examination trauma questions. A chi-square analysis with Yates correction was used to determine differences. Questions and literature were similar in the most frequently addressed items in each of the 4 areas: category type (taxonomy 3, treatment), 52.4% and 60.7%, respectively; anatomic location (femur), 23.3% and 27.7%, respectively; orthopedic focus (fracture), 51.0% and 56.5%, respectively; and treatment type (multiple/nonspecific), 39.0% and 35.4%, respectively.The content correlation found between the questions and literature supports the idea that reviewing current literature may help prepare for the trauma content on the Orthopaedic In-Training Examination.

  14. Occlusion in implant dentistry. A review of the literature of prosthetic determinants and current concepts.

    Gross, M D

    2008-06-01

    Today the clinician is faced with widely varying concepts regarding the number, location, distribution and inclination of implants required to support the functional and parafunctional demands of occlusal loading. Primary clinical dilemmas of planning for maximal or minimal numbers of implants, their axial inclination, lengths and required volume and quality of supporting bone remain largely unanswered by adequate clinical outcome research. Planning and executing optimal occlusion schemes is an integral part of implant supported restorations. In its wider sense this includes considerations of multiple inter-relating factors of ensuring adequate bone support, implant location number, length, distribution and inclination, splinting, vertical dimension aesthetics, static and dynamic occlusal schemes and more. Current concepts and research on occlusal loading and overloading are reviewed together with clinical outcome and biomechanical studies and their clinical relevance discussed. A comparison between teeth and implants regarding their proprioceptive properties and mechanisms of supporting functional and parafunctional loading is made and clinical applications made regarding current concepts in restoring the partially edentulous dentition. The relevance of occlusal traumatism and fatigue microdamage alone or in combination with periodontal or peri-implant inflammation is reviewed and applied to clinical considerations regarding splinting of adjacent implants and teeth, posterior support and eccentric guidance schemes. Occlusal restoration of the natural dentition has classically been divided into considerations of planning for sufficient posterior support, occlusal vertical dimension and eccentric guidance to provide comfort and aesthetics. Mutual protection and anterior disclusion have come to be considered as acceptable therapeutic modalities. These concepts have been transferred to the restoration of implant-supported restoration largely by default. However, in

    Full Text Available One important modality of breast cancer therapy is surgical treatment, which has become increasingly less mutilating over the last century. Breast reconstruction has become an integrated part of breast cancer treatment due to long-term psychosexual health factors and its importance for breast cancer survivors. Both autogenous tissue-based and implant-based reconstruction provides satisfactory reconstructive options due to better surgeon awareness of “the ideal breast size”, although each has its own advantages and disadvantages. An overview of the current options in breast reconstruction is presented in this article.

    Full Text Available Recent studies have begun to bridge the gap between general and workplace pro-environmental behavior by adapting specific existing behavioral models to the workplace environment. This conceptual article proposes a different approach by synthesizing the current general and workplace literature to develop a new model of the antecedents to pro-environmental behavior. Guided by this approach, this paper combines the insights of the current general and workplace models to develop an integrated framework of pro-environmental behavior in the workplace. In doing so, an overview of the current general and workplace literatures will be provided as well as their similarities and differences highlighted. The proposed framework will provide further insights into the antecedents of workplace pro-environmental behavior and identify common findings across the different existing workplace models. This theory can be the basis for further research in order to provide a comprehensive picture of the antecedents of pro-environmental behavior in the workplace. Lastly, implications for specific interventions to develop targeted Human Resource Management practices and work towards achieving environmental sustainability will be discussed.

    In the past few decades, several devastating heat wave events have significantly challenged public health. As these events are projected to increase in both severity and frequency in the future, it is important to assess the relationship between heat waves and the health indicators that can be used in the early warning systems to guide the public health response. Yet there is a knowledge gap in the impact of heat waves on morbidity. In this study, a comprehensive review was conducted to assess the relationship between heat waves and different morbidity indicators, and to identify the vulnerable populations. The PubMed and ScienceDirect database were used to retrieve published literature in English from 1985 to 2014 on the relationship between heat waves and morbidity, and the following MeSH terms and keywords were used: heat wave, heat wave, morbidity, hospital admission, hospitalization, emergency call, emergency medical services, and outpatient visit. Thirty-three studies were included in the final analysis. Most studies found a short-term negative health impact of heat waves on morbidity. The elderly, children, and males were more vulnerable during heat waves, and the medical care demand increased for those with existing chronic diseases. Some social factors, such as lower socioeconomic status, can contribute to heat-susceptibility. In terms of study methods and heat wave definitions, there remain inconsistencies and uncertainties. Relevant policies and guidelines need to be developed to protect vulnerable populations. Morbidity indicators should be adopted in heat wave early warning systems in order to guide the effective implementation of public health actions.

    The declining number of physician scientists is an alarming issue. A systematic review of all existing programs described in the literature was performed, so as to highlight which programs may serve as the best models for the training of successful physician scientists. Multiple databases were searched, and 1,294 articles related to physician scientist training were identified. Preference was given to studies that looked at number of confirmed publications and/or research grants as primary outcomes. Thirteen programs were identified in nine studies. Eighty-three percent of Medical Scientist Training Program (MSTP) graduates, 77% of Clinician Investigator Training Program (CI) graduates, and only 16% of Medical Fellows Program graduates entered a career in academics. Seventy-eight percent of MSTP graduates succeeded in obtaining National Institute of Health (NIH) grants, while only 15% of Mayo Clinic National Research Service Award-T32 graduates obtained NIH grants. MSTP physician scientists who graduated in 1990 had 13.5 ± 12.5 publications, while MSTP physician scientists who graduated in 1975 had 51.2 ± 38.3 publications. Additionally, graduates from the Mayo Clinic's MD-PhD Program, the CI Program, and the NSRA Program had 18.2 ± 20.1, 26.5 ± 24.5, and 17.9 ± 26.3 publications, respectively. MSTP is a successful model for the training of physician scientists in the United States, but training at the postgraduate level also shows promising outcomes. An increase in the number of positions available for training at the postgraduate level should be considered.

    Patients with pectus excavatum (PE) often describe improvements in exercise stamina following corrective surgery. Studies have investigated the surgical effect on physiological parameters; still, no consensus has yet been reached. Therefore, the aim of this literature review was to describe the cardiac outcome after surgical correction, both at rest and during exercise. In February 2016, a detailed search of the databases PubMed, Medline, and EMBASE was performed. We assessed clinical studies that described cardiac outcomes both before and after surgical correction of PE. We only included studies reporting either pre-defined echocardiographic or exercise test parameters. No exclusion criteria or statistical analyses were applied. Twenty-one full-text articles, published between 1972 and 2016, were selected, with cohort-ranges of 3-168 patients, mean age-ranges of 5-33 years, and mean follow-up-ranges from immediately to 4 years after surgery. Twelve studies described resting cardiac parameters. Four studies measured cardiac output, where one described 36% immediate increase after surgery, one reported 15% increase after Nuss-bar removal and two found no difference. Three studies demonstrated improvement in mean stroke volume ranges of 22-34% and two studies found no difference. Fifteen studies investigated exercise capacity, with 11 considering peak O2 pr. kg, where five studies demonstrated improvements with the mean ranging from 8% to 15% after surgery, five studies demonstrated no difference, and one saw a decrease of 19% 3 months after Nuss-bar implantation. A measurable increase in exercise capacity exists following surgery, which may be caused by multiple factors. This may be owed to the relief of compressed cardiac chambers with the increased anterior-posterior thoracic dimensions, which could facilitate an improved filling of the heart. With these results, the positive physiological impact of the surgery is emphasized and the potential gain in cardiac

    Reflecting on the past year, the number of publications on myofascial pain continues to increase in a steady rate. The current review includes 30 basic and clinical studies, case reports, reviews, and reports from fifteen different countries about trigger points (TrP), myofascial pain (MP), dry needling (DN) and other related interventions. We are pleased that during 2015 this article made the top 15 of most downloaded articles as many as three times! In general, the quality of published papers is improving as well. Nevertheless, several papers included in this overview, mention the application of "ischemic compression", which is a questionable concept in the context of TrP inactivation. As we have outlined previously, in the current thinking about myofascial pain, TrPs feature significant hypoxia and a lowered pH (Ballyns et al., 2011; Shah and Gilliams, 2008), and attempts to induce more ischemia would be counterproductive. Already in 1999, Simons, Travell and Simons changed the terminology from ischemic compression to TrP compression (Simons et al., 1999) and we recommend that contemporary researchers and clinicians adopt the new terminology and stop using the term "ischemic compression."

    Reflecting the popularity of nature-based activities such as hiking and mountain biking, there are thousands of kilometres of recreational trails worldwide traversing a range of natural areas. These trails have environmental impacts on soils and vegetation, but where has there been research, what impacts have been found and how were they measured? Using a systematic quantitative literature review methodology, we assessed the impacts of trails on vegetation and soils, highlighting what is known, but also key knowledge gaps. Of the 59 original research papers identified on this topic that have been published in English language peer-reviewed academic journals, most were for research conducted in protected areas (71%), with few from developing countries (17%) or threatened ecosystems (14%). The research is concentrated in a few habitats and biodiversity hotspots, mainly temperate woodland, alpine grassland and Mediterranean habitats, often in the USA (32%) or Australia (20%). Most examined formal trails, with just 15% examining informal trails and 11% assessing both types. Nearly all papers report the results of observational surveys (90%), collecting quantitative data (66%) with 24% using geographic information systems. There was an emphasis on assessing trail impacts at a local scale, either on the trail itself and/or over short gradients away from the trail edge. Many assessed changes in composition and to some degree, structure, of vegetation and soils with the most common impacts documented including reduced vegetation cover, changes in plant species composition, trail widening, soil loss and soil compaction. There were 14 papers assessing how these local impacts can accumulate at the landscape scale. Few papers assessed differences in impacts among trails (7 papers), changes in impacts over time (4), species-specific responses (3) and only one assessed effects on plant community functioning. This review provides evidence that there are key research gaps

    Antibiotics are medicines used to prevent and treat bacterial infections. Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Antibiotic resistance is rising to dangerously high levels in all parts of the world, leading to higher medical costs, prolonged hospital stays, and increased mortality. In the European Union alone, drug-resistant bacteria are estimated to cause 25,000 deaths and cost more than US$1.5 billion every year in healthcare expenses and productivity losses. The problems of antibiotic misuse and antibiotic resistance are quite serious in China. In 2015, results of a study by the State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences indicated that the total antibiotic usage in China in 2013 was approximately 162,000 tons, including human use (48%) and use in animals (52%). This amount accounted for about half of the antibiotic usage worldwide. The per-capita use of antibiotics in China is more than 5 times that in Europe and the United States. These data mean that China is one of the world's leading countries with serious problems in terms of antibiotic misuse and antibiotic resistance. The current article analyzes the current state and harms of antibiotic misuse and causes of antibiotic resistance in China. The Government needs to pay close attention to the issue of antibiotic resistance in China and formulate a strategy at the national level. Thus, the following suggestions are offered: i) The Chinese Government should implement policies that promote antibiotic research and development; ii) Medical facilities in China should create multidisciplinary teams (MDTs) and encourage early action by MDTs to control the spread of multi-drug-resistant bacteria (MDRB); iii) An intervention in the form of health education should target patients and accompanying family members (AFM) in China. In other words, antibiotic resistance is not a personal problem but an

    The authors reviewed the evidence on performance improvement methods for increasing emergency department (ED) patient satisfaction to provide evidence-based suggestions for clinical practice. Data sources consisted of searches through MEDLINE, CINAHL, PSYCHINFO, Cochrane Library, and Emergency Medicine Abstracts and a manual search of references. Articles were included if they reported a performance improvement intervention targeting patient satisfaction in the ED setting. Articles on studies not conducted in the United States or that failed to provide enough details to allow critical evaluation of the study were excluded. Two authors used structured evaluation criteria to independently review each retained study. Nineteen articles met all selection criteria. Three studies found varying levels of support for multicomponent interventions, predominantly focused on implementation of clinical practice guidelines for specific presenting complaints and process redesign. Sixteen studies evaluated single-component interventions, with the following having at least one supportive study: using alternating patient assignment to provider teams rather than "zone"-based assignment, enhancing provider communication and customer service skills, incorporating information delivery interventions (e.g., pamphlets, video) that target patient expectations, using preformatted charts, and establishing ED-based observation units for specific conditions such as asthma and chest pain. There is modest evidence supporting a range of performance improvement interventions for improving ED patient satisfaction. Further work is needed before specific, evidence-based recommendations can be made regarding which process changes are most effective. Recommendations are made for improving the quality of performance improvement efforts in the ED setting.

    Full Text Available Apolipoprotein E (ApoE ε4 allele represents a well known vascular risk factor for developing Alzheimer disease (AD and differences in ApoE genotypes may explain a part of the variability in AD phenotypes. In fact, ApoE ε4 allele possession seems to be associated with a more precocious age of onset, greater episodic memory impairment, and psychotic symptoms. The first question we discuss regards the role of ApoE ε4 on cognitive progression of AD. In fact, while a general agreement exists about the role played by ApoE ε4 on the precocious onset of AD, cognitive decline has been differently associated with ApoE ε4 allele possession in AD patients in a continuum of faster decline, no effect, and slower decline. An attemptable interpretation is that the biological processes leading to the onset of AD are different from those involved in determining its clinical course. The second question regards the possible relationship between the presence of the degenerative pathological hallmarks of the disease in specific cerebral areas and different cognitive or behavioural symptoms. In fact, there is evidence that degenerative pathology in hippocampal formation and frontal cortex reflects the progression of cognitive deficits in brain aging and AD and that hypometabolism in right frontal lobe and greater frontal neuropsychological deficits occur in AD patients with psychosis in comparison to those without. The third question regards, specifically, the relationship between ApoE ε4 variant and behavioural symptoms. In fact, there is evidence supporting the link between being carriers of ApoE ε4 allele and severity of delusions, mostly at the early stage of the illness. In an interpretative challenge, we suggest that the link between being carriers of ApoE ε4 allele and suffering from delusions in AD may be explained by frontal lobe dysfunctions. Finally, we hypothesize that the most precocious onset of AD illness, described in carriers of ApoE ε4

The patch currently on the US market contains 150 µg norelgestromin and 35 µg ethinylestradiol (EE. The 20 cm2 patch is applied once weekly for 3 weeks, followed by a patch-free week, for a 21–7 cycle. Typical failure rates are similar to that of combined oral contraceptives (COCs. Transdermal delivery results in less peaks and troughs of estrogen, but a higher total estrogen exposure compared with COCs. Though studies show mixed results, the risk of developing venous thromboembolism (VTE is about twice as high with the patch as with COCs; however, the absolute risk of VTE remains low. The side effect profile is similar to that of COCs, with slightly higher rates of breast tenderness plus a unique adverse effect of application site reactions. Two new patches have been developed, one containing gestodene and EE in Europe and another containing levonorgestrel and EE. Overall, the patch provides an alternative to COCs for women who want autonomy and the benefit of not needing to take a pill daily, with similar efficacy and tolerability. Keywords: contraceptive patch, Ortho-Evra, transdermal, levonorgestrel patch, gestodene patch, hormonal patch

    To describe existing bladder and bowel specific quality of life (QoL) measurement tools, QoL in patients with multiple sclerosis (MS), spinal cord injury (SCI), Parkinson's Disease (PD), stroke, or spina bifida (SB) affected by bladder or bowel dysfunction, and the impact of specific bladder and bowel management on QoL. We performed a systematic review in PubMed/Medline databases in accordance with the PRISMA statement for English publications between January 1, 2000 and January 1, 2014. Articles were first screened based on their abstract and select full-text articles were then reviewed for eligibility. Articles with no QoL or PROM assessing urinary or bowel dysfunction were excluded. Risk of bias assessment included randomization, incomplete outcomes data, selective outcomes reporting, and other biases. All articles were graded using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system as per the Cochrane Handbook for Systematic Reviews of Interventions. The most common QoL measurement tool for urinary and bowel dysfunction was the Medical Outcomes Study SF-36. Twelve (24%) studies used only non-validated QoL questionnaires. Only three urinary or bowel specific QoL measures were found: the Qualiveen questionnaire, the FICQoL, and the QoL-BM. Several studies identified instances were clinical and patient-reported outcomes were inconsistent particularly with indwelling urinary catheter usage and reconstructive surgery. Additionally, certain clinical outcomes surrogates commonly used as primary outcomes measures may not correlate with the patient reported outcomes (PRO). Current PRO measures (PROM) and QoL assessments are heterogeneous and several inconsistencies in clinical and PRO for various management options exist. Standardized PROM will help identify optimal bladder and bowel management for patients with neurologic conditions. © 2014 Wiley Periodicals, Inc.

    Full Text Available Backgound and Objectives: Infections related to central venous catheter (CVC use constitute an important a problem. It is estimated that approximately 90% of bloodstream infections (BSI are caused by CVC use. This study aims at reviewing the risk factors and current recommendations for prevention of infections associated with central venous catheter use. Methods: A total of 12 articles published in the last 5 years and indexed in the databases of the Latin American and Caribbean Literature on Health Sciences (LILACS, Nursing Database (BDENF, International Literature on Health Sciences (Medline/Pubmed were selected, as well as publications related to the recommendations for BSI prevention, such as: Institute for Healthcare Improvement (IHI, Centers for Disease Control and Prevention (CDC and the National Health Surveillance Agency (ANVISA. Results: Two categories were identified: prevention and control measures and risk factors for BSI associated with central venous catheter use. Conclusions: Some recommendations that were well-defined over the years have been questioned by some authors and continuing training and education of the multidisciplinary team are the most important factors for the prevention of bloodstream infections associated with CVC use.

    Considerable interest in the relationship between biodiversity and disease has recently captured the attention of the research community, with important public policy implications. In particular, malaria in the Amazon region is often cited as an example of how forest conservation can improve public health outcomes. However, despite a growing body of literature and an increased understanding of the relationship between malaria and land use / land cover change (LULC) in Amazonia, contradictions have emerged. While some studies report that deforestation increases malaria risk, others claim the opposite. Assessing malaria risk requires examination of dynamic processes among three main components: (i) the environment (i.e. LULC and landscape transformations), (ii) vector biology (e.g. mosquito species distributions, vector activity and life cycle, plasmodium infection rates), and (iii) human populations (e.g. forest-related activity, host susceptibility, movement patterns). In this paper, we conduct a systematic literature review on malaria risk and deforestation in the Amazon focusing on these three components. We explore key features that are likely to generate these contrasting results using the reviewed articles and our own data from Brazil and Peru, and conclude with suggestions for productive avenues in future research.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'. © 2017 The Authors.

    Vacuum massage is a non-invasive mechanical massage technique performed with a mechanical device that lifts the skin by means of suction, creates a skin fold and mobilises that skin fold. In the late 1970s, this therapy was introduced to treat traumatic or burn scars. Although vacuum massage was invented to treat burns and scars, one can find very little literature on the effects of this intervention. Therefore, the aim of this review is to present an overview of the available literature on the physical and physiological effects of vacuum massage on epidermal and dermal skin structures in order to find the underlying working mechanisms that could benefit the healing of burns and scars. The discussion contains translational analysis of the results and provides recommendations for future research on the topic. An extended search for publications was performed using PubMed, Web of Science and Google Scholar. Two authors independently identified and checked each study against the inclusion criteria. Nineteen articles were included in the qualitative synthesis. The two most reported physical effects of vacuum massage were improvement of the tissue hardness and the elasticity of the skin. Besides physical effects, a variety of physiological effects are reported in literature, for example, an increased number of fibroblasts and collagen fibres accompanied by an alteration of fibroblast phenotype and collagen orientation. Little information was found on the decrease of pain and itch due to vacuum massage. Although vacuum massage initially had been developed for the treatment of burn scars, this literature review found little evidence for the efficacy of this treatment. Variations in duration, amplitude or frequency of the treatment have a substantial influence on collagen restructuring and reorientation, thus implying possible beneficial influences on the healing potential by mechanotransduction pathways. Vacuum massage may release the mechanical tension associated with

    Rehabilitation applications using brain-computer interfaces (BCI) have recently shown encouraging results for motor recovery. Effective BCI neurorehabilitation has been shown to exploit neuroplastic properties of the brain through mental imagery tasks. However, these applications and results are currently restricted to adults. A systematic search reveals there is essentially no literature describing motor rehabilitative BCI applications that use electroencephalograms (EEG) in children, despite advances in such applications with adults. Further inspection highlights limited literature pursuing research in the field, especially outside of neurofeedback paradigms. Then the question naturally arises, do current literature trends indicate that EEG based BCI motor rehabilitation applications could be translated to children? To provide further evidence beyond the available literature for this particular topic, we present an exploratory survey examining some of the indirect literature related to motor rehabilitation BCI in children. Our goal is to establish if evidence in the related literature supports research on this topic and if the related studies can help explain the dearth of current research in this area. The investigation found positive literature trends in the indirect studies which support translating these BCI applications to children and provide insight into potential pitfalls perhaps responsible for the limited literature. Careful consideration of these pitfalls in conjunction with support from the literature emphasize that fully realized motor rehabilitation BCI applications for children are feasible and would be beneficial. • BCI intervention has improved motor recovery in adult patients and offer supplementary rehabilitation options to patients. • A systematic literature search revealed that essentially no research has been conducted bringing motor rehabilitation BCI applications to children, despite advances in BCI. • Indirect studies discovered

    2015-05-01

    Full Text Available Background: Studies have found that metals are emitted to the electronic cigarette (EC aerosol. However, the potential health impact of exposure to such metals has not been adequately defined. The purpose of this study was to perform a risk assessment analysis, evaluating the exposure of electronic cigarette (EC users to metal emissions based on findings from the published literature. Methods: Two studies were found in the literature, measuring metals emitted to the aerosol from 13 EC products. We estimated that users take on average 600 EC puffs per day, but we evaluated the daily exposure from 1200 puffs. Estimates of exposure were compared with the chronic Permissible Daily Exposure (PDE from inhalational medications defined by the U.S. Pharmacopeia (cadmium, chromium, copper, lead and nickel, the Minimal Risk Level (MRL defined by the Agency for Toxic Substances and Disease Registry (manganese and the Recommended Exposure Limit (REL defined by the National Institute of Occupational Safety and Health (aluminum, barium, iron, tin, titanium, zinc and zirconium. Results: The average daily exposure from 13 EC products was 2.6 to 387 times lower than the safety cut-off point of PDEs, 325 times lower than the safety limit of MRL and 665 to 77,514 times lower than the safety cut-off point of RELs. Only one of the 13 products was found to result in exposure 10% higher than PDE for one metal (cadmium at the extreme daily use of 1200 puffs. Significant differences in emissions between products were observed. Conclusions: Based on currently available data, overall exposure to metals from EC use is not expected to be of significant health concern for smokers switching to EC use, but is an unnecessary source of exposure for never-smokers. Metal analysis should be expanded to more products and exposure can be further reduced through improvements in product quality and appropriate choice of materials.

    A growing body of evidence suggests that omega (ω)-3 polyunsaturated fatty acids (PUFAs) are clinically useful in patients with psychiatric disorders. In the present review, we summarize the findings of randomized, placebo-controlled clinical trials that have focused on the potential therapeutic utility of ω-3 PUFAs in patients with mental illnesses. We searched the PubMed database for placebo-controlled clinical trials using the keywords "PUFAs", "omega-3", "eicosapentaenoic acid", and "docosahexaenoic acid" in combination with the following terms: "anxiety disorders", "mood disorders", "autism", "attention-deficit hyperactivity disorder" (ADHD), "personality disorders", and "schizophrenia". The literature review indicated that personality disorders, autism, and anxiety disorders have been investigated less frequently than mood disorders, schizophrenia, and ADHD. Although no definite conclusions can be drawn on the therapeutic efficacy of ω-3 PUFAs in the majority of the psychiatric illnesses examined here, the evidence suggests that these molecules have a potential preventive role in people at extremely high risk for developing psychosis. Future studies in the field should examine ω-PUFAs turnover in neural membranes. Moreover, special attention should be paid to potential confounds, such as smoking and dietary habits.

    This article discusses the results of a literature review that has assessed the impact of Female Genital Mutilation (FGM) legislation in 28 countries (27 in Africa and Yemen) where FGM is concentrated. Evidence on the impact of FGM legislation was available on prevalence of FGM; changes in societal attitudes and perceptions of FGM; knowledge and awareness of FGM legislation and consequences, and the impact on medicalization. While the majority of countries have adopted legal frameworks prohibiting FGM, these measures have been ineffective in preventing and/or in accelerating the abandonment of the practice. Anti-FGM laws have had an impact on prevalence in only two countries where strict enforcement of legal measures has been complemented by robust monitoring, coupled with robust advocacy efforts in communities. Owing to poor enforcement and lax penalties, legal measures have had a limited impact on medicalization. Similarly, legal frameworks have had a limited impact on societal attitudes and perceptions of FGM, with evidence suggesting rigid enforcement of FGM laws has in some instances been counterproductive. Although evidence suggests legislation has not influenced the decline in FGM in the majority of countries, legal frameworks are nevertheless key components of a comprehensive response to the elimination and abandonment of the practice, and need to be complemented by measures that address the underlying socio-cultural norms that are the root of this practice.

    Objective. Existing research shows a serious scarcity of EBPH practice in China and other developing regions; as an exploratory study, this study aimed to assess the current EBPH implementation status in Shanghai of China qualitatively. Methods. Using semistructured key informant interviews, we examined the status of and impediments to the lagging EBPH in China. Data were analyzed based on the Consolidated Framework for Implementation Research (CFIR). Results. Chinese public health practitioners knew more about evidence-based medicine but less about EBPH. The situation was worse in community healthcare centers. Participants perceived that evidence sources were limited and the quality of evidence was low. Concerning the inner setting factors, the structural characteristics, networks and communications, implementation climate, and leadership engagement were confronted with many problems. Among the outer setting factors, external government policies and incentives and low patient compliance were the key problems. Additionally, public health practitioners in Shanghai lacked sufficient awareness of EBPH. Furthermore, the current project-based EBPH lacks a systematic implementation system. Conclusions. Existing practical perspectives on EBPH indicate a lag in the advocacy of this new ideology in China. It would be advisable for healthcare institutions to take the initiative to explore feasible and multiple methods of EBPH promotion.

    Advanced imaging of veterinary cancer patients has evolved in recent years and modalities once limited to human medicine have now been described for diagnostic purposes in veterinary medicine (positron emission tomography/computed tomography, single-photon emission computed tomography, whole body magnetic resonance imaging). Magnetic resonance spectroscopy (MRS) is a non-invasive and non-ionizing technique that is well described in the human medical literature and is most frequently used to evaluate the metabolic activity of tissues with questionable malignant transformation. Differentiation of neoplastic tissue from surrounding normal tissue is dependent on variations in cellular metabolism. Positive identification of malignancy can be made when neoplastic alterations are occurring at the cellular level prior to gross anatomic changes. This improved, early detection of cancer occurrence (or recurrence) can improve patient survival and direct medical therapy. MRS techniques are largely underutilized in veterinary medicine, with current research predominantly limited to the brain (both evaluation of normal and diseased tissue). Given the clinical utility of MRS in humans, the technique may also be useful in the staging of cancer in veterinary medicine.

    To review the current literature on the use of hyperbaric oxygen (HBO₂) therapy in the treatment of osteonecrosis of the femoral head (ONFH). We searched PubMed, Directory of Open Access Journals (DOAJ), EMBASE, Web of Science, Academic Search Complete, CINAHL and MEDLINE through April 2015. We hand-searched relevant textbooks, conference proceedings and the reference lists of review articles and clinical studies Randomized controlled trials (RCT) and observational studies (cohort study, case-control study, case series) that reported the outcome of patients who received HBO₂therapy for ONFH were included. Only English-language articles were included. Study quality was not used as an exclusion criterion. Two authors independently assessed trials for inclusion, extracted data and presented to other authors. Disagreements were resolved by consensus. We identified eight clinical studies; two randomized controlled trials (RCTs); one historically controlled study; and five case series. The majority of the studies were small-scale, heterogeneous and methodologically weak. In four of the studies HBO₂therapy was combined with other treatment modalities, making it impossible to draw firm conclusions on the specific effects of HBO₂therapy. Hip survivorship in studies wherein HBO₂therapy was used alone was 95.5% in Steinberg Stage I lesions, 89% in Steinberg Stage II lesions and 100% in Ficat Stage II lesions. There is a room for HBO₂therapy in the management ONFH. Further RCTs, however, are required to better elucidate the role of HBO₂therapy in the treatment of ONFH.

  10. Theories of Suggestion.

    Science.gov (United States)

    Brown, W

    1928-02-01

    The word "suggestion" has been used in educational, scientific and medical literature in slightly different senses. In psychological medicine the use of suggestion has developed out of the earlier use of hypnotic influence.Charcot defined hypnosis as an artificial hysteria, Bernheim as an artificially increased suggestibility. The two definitions need to be combined to give an adequate account of hypnosis. Moreover, due allowance should be made for the factors of dissociation and of rapport in hypnotic phenomena.The relationships between dissociation, suggestibility, and hypnotizability.Theories of suggestion propounded by Pierre Janet, Freud, McDougall, Pawlow and others. Ernest Jones's theory of the nature of auto-suggestion. Janet explains suggestion in terms of ideo-motor action in which the suggested idea, because of the inactivity of competing ideas, produces its maximum effect. Freud explains rapport in terms of the sex instinct "inhibited in its aim" (transference) and brings in his distinction of "ego" and "ego-ideal" (or "super-ego") to supplement the theory. Jones explains auto-suggestion in terms of narcissism. McDougall explains hypnotic suggestion in terms of the instinct of self-abasement. But different instincts may supply the driving power to produce suggestion-effects in different circumstances. Such instincts as those of self-preservation (fear) and gregariousness may play their part. Auto-suggestion as a therapeutic factor is badly named. It supplements, but does not supplant the will, and makes complete volition possible.

    Regulation of fluid and dietary intake habits is essential in comprehensive preventive management of urolithiasis. However, despite large body of epidemiological database, there is dearth of good quality prospective interventional studies in this regard. Often there is conflict in pathophysiological basis and actual clinical outcome. We describe conflicts, controversies and lacunae in current literature in fluid and dietary modifications in prevention of urolithiasis. Adequate fluid intake is the most important conservative strategy in urolithiasis-prevention; its positive effects are seen even at low volumes. Of the citrus, orange provides the most favorable pH changes in the urine, equivalent to therapeutic alkaline citrates. Despite being richest source of citrate, lemon does not increase pH significant due to its acidic nature. Fructose, animal proteins and fats are implicated in contributing to obesity, which is an established risk factor for urolithiasis. Fructose and proteins also contribute to lithogenecity of urine directly. Sodium restriction is commonly advised since natriuresis is associated with calciuresis. Calcium restriction is not advisable for urolithiasis prevention. Adequate calcium intake is beneficial if taken with food since it reduces absorption of dietary oxalate. Increasing dietary fiber does not protect against urolithiasis. Evidence for pyridoxine and magnesium is not robust. There is no prospective interventional study evaluating effect of many dietary elements, including citrus juices, carbohydrate, fat, dietary fiber, sodium, etc. Due to lack of good-quality prospective interventional trials it is essential to test the findings of pathophysiological understanding and epidemiological evidence. Role of probiotics and phytoceuticals needs special attention for future research.

    Background Chronic obstructive pulmonary disease (COPD) is a serious long-term lung disease in which the airflow from the lungs is progressively reduced. By 2030, COPD will become the third cause of mortality and seventh cause of morbidity worldwide. With advances in technology and mobile communications, significant progress in the mobile health (mHealth) sector has been recently observed. Mobile phones with app capabilities (smartphones) are now considered as potential media for the self-management of certain types of diseases such as asthma, cancer, COPD, or cardiovascular diseases. While many mobile apps for patients with COPD are currently found on the market, there is little published material on the effectiveness of most of them, their features, and their adoption in health care settings. Objectives The aim of this study was to search the literature for current systems related to COPD and identify any missing links and studies that were carried out to evaluate the effectiveness of COPD mobile apps. In addition, we reviewed existing mHealth apps from different stores in order to identify features that can be considered in the initial design of a COPD support tool to improve health care services and patient outcomes. Methods In total, 206 articles related to COPD management systems were identified from different databases. Irrelevant materials and duplicates were excluded. Of those, 38 articles were reviewed to extract important features. We identified 214 apps from online stores. Following exclusion of irrelevant apps, 48 were selected and 20 of them were downloaded to review some of their common features. Results Our review found that out of the 20 apps downloaded, 13 (65%, 13/20) had an education section, 5 (25%, 5/20) consisted of medication and guidelines, 6 (30%, 6/20) included a calendar or diary and other features such as reminders or symptom tracking. There was little published material on the effectiveness of the identified COPD apps. Features such as

    2014-06-01

    The majority of health behavior research involving college students in the United States has focused on 4-year college students. Two-year or community college students have been less studied, although a significant proportion of U.S. undergraduates, primarily those from disadvantaged socioeconomic and/or racial/ethnic background, are enrolled in community colleges. Thus, there is a need to enhance health behavior and health promotion research among community college students. This study systematically reviewed 42 published, peer-reviewed health behavior studies conducted among U.S. community college students in order to determine the current state of research in the area with regard to behaviors studied, research designs used, recruitment and data collection strategies practiced, rates of student participation, and characteristics of the participants represented. Findings identified the methodological limitations of current research and suggested optimal recruitment and data collection methods suitable for various research needs. Findings are discussed in the context of enhancing health behavior research among U.S. community college students.

    Full Text Available OBJETIVO: Revisar a literatura sobre a perda auditiva associada ao envelhecimento e suas implicações, numa perspectiva atual. REVISÃO DA LITERATURA: Nos estudos realizados no Brasil, a presbiacusia vem sendo apontada como causa mais freqüente da deficiência auditiva em pessoas idosas, implicando em uma dificuldade de compreensão durante a comunicação verbal. Estudos internacionais também mostram alta prevalência da perda auditiva em pessoas idosas. DISCUSSÃO: Segundo pesquisas recentes, à medida que o quantitativo da população idosa vem aumentando, também aumenta a prevalência da presbiacusia que interfere na qualidade de vida do idoso. Mesmo entre os profissionais de saúde, ainda é grande o desconhecimento em relação às vantagens e ganhos que a reeducação auditiva específica para idosos com perda auditiva pode oferecer. CONCLUSÃO: Os artigos aqui analisados mostraram que os serviços de saúde da rede pública, que envolvem médicos e fonoaudiólogos, devem estabelecer diretrizes para o desenvolvimento de programas de diagnóstico, aquisição de aparelhos de amplificação sonora individual e, principalmente, de reeducação auditiva para os idosos portadores de presbiacusia, para que eles possam participar e desfrutar das relações sociais, mantendo uma boa qualidade de vida. Entretanto, no Brasil, os estudos e pesquisas nesta área estão apenas começando.AIM: to review the literature on aging-related hearing loss and its current impacts. LITERATURE REVIEW: In studies carried out in Brazil, presbycusis has been blamed for being the most frequent cause of hearing loss in the elderly, causing verbal communication impairment. International studies also show the high prevalence of hearing loss in the elderly. DISCUSSION: According to recent investigations, as the number of elderly people increase, the prevalence of presbycusis interfering in the life quality of this population also increases.

Literary Spaces of Kashubia is to elaborate and present the anthropological outline of the Kashubian literature. He focuses on selected (anthropological points of reference, i.e. leading motives in the Kashubian culture/literature. They are, on the one hand, childhood, femininity, masculinity, and on the other hand, the values which are fundamentally related to the spiritual culture of Kashubia: the native land (tatczëzna, rodnô zemia and the Kashubian language (rodnô mòwa. Presentation of these motifs occurs in the cultural conditions of Polish tradition. The anthropological outline of the Kashubian literature is presented by Kuik-Kalinowska from two perspectives: in the “local” plane, i.e. in the context of social and cultural phenomena specific only for the Kashubian culture, and in a more general context, by emphasizing its universal aspects. Both perspectives are to show both what in the Kashubian culture and literature is regional, ethnic, own, as well as what is universal, of a general character, often unconscious to the writers. According to the researcher, the variety of themes and motifs of the Kashubian literature indicates its maturity and artistic self-sufficiency, and this puts it on an equal grounds with other literatures.

    Full Text Available Abstract Background It is well established that drinking alcohol raises the risk of liver cancer (hepatocellular carcinoma. However, it has not been sufficiently established as to whether or not drinking cessation subsequently reduces the risk of liver cancer and if it does reduce the risk how long it takes for this heightened risk to fall to that of never drinkers. This question is important for effective policy design and evaluation, to establish causality and for motivational treatments. Methods A systematic review and meta-analysis using the current available evidence and a specific form of Generalised Least Squares is performed to assess how the risk of liver cancer changes with time for former drinkers. Results Four studies are found to have quantified the effect of drinking cessation on the risk of liver cancer. The meta-analysis suggests that the risk of liver cancer does indeed fall after cessation by 6-7% a year, but there remains a large uncertainty around this estimate both statistically and in its interpretation. As an illustration it is estimated that a time period of 23 years is required after drinking cessation, with a correspondingly large 95% confidence interval of 14 to 70 years, for the risk of liver cancer to be equal to that of never drinkers. Conclusion This is a relatively under researched area and this is reflected in the uncertainty of the findings. It is our view that it is not possible to extrapolate the results found here to the general population. Too few studies have addressed this question and of the studies that have, all have significant limitations. The key issue amongst the relevant studies is that it appears that current drinkers, abstainers and former drinkers are not composed of, or effectively adjusted to be, similar populations making inferences about risk changes impossible. This is a very difficult area to study effectively, but it is an important topic. More work is required to reduce both statistical

    Spinal cord injury (SCI) can cause severe traumatic injury to the central nervous system (CNS). Current therapeutic effects achieved for SCI in clinical medicine show that there is still a long way to go to reach the desired goal of full or significant functional recovery. In basic medical research, however, cell transplantation, gene therapy, application of cytokines, and biomaterial scaffolds have been widely used and investigated as treatments for SCI. All of these strategies when used separately would help rebuild, to some extent, the neural circuits in the lesion area of the spinal cord. In light of this, it is generally accepted that a combined treatment may be a more effective strategy. This review focuses primarily on our recent series of work on transplantation of Schwann cells and adult stem cells, and transplantation of stem cell-derived neural network scaffolds with functional synapses. Arising from this, an artificial neural network (an exogenous neuronal relay) has been designed and fabricated by us-a biomaterial scaffold implanted with Schwann cells modified by the neurotrophin-3 (NT-3) gene and adult stem cells modified with the TrkC (receptor of NT-3) gene. More importantly, experimental evidence suggests that the novel artificial network can integrate with the host tissue and serve as an exogenous neuronal relay for signal transfer and functional improvement of SCI.

    Conducted electrical weapons (CEWs) such as the TASER(®) M- and X-series deliver short high-voltage, low-current energy pulses to temporarily paralyze a person by causing electrical interruption of the body's normal energy pulses. Despite many scientific publications, which classify the health risks of an appropriate use of the TASER device as minor, there still is a continuous uncertainty about possible side effects with human application. Based on a literature search of the National Library of Medicine's MEDLINE database's PubMed system of current publications, the following article describes the mechanisms by which the device operates and discusses possible pathophysiological consequences. The majority of current human literature has not found evidence of clinical relevant pathophysiological effects during and after an exposure of professionally applied CEWs. However, to be able to exclude possible health risks, a medical checkup of people who have been exposed to CEWs is essential.

    2013-06-01

    Extensive research has identified stereotypic behavioral and biological abnormalities in post-traumatic stress disorder (PTSD), such as heightened autonomic activity, an exaggerated startle response, reduced basal cortisol levels and cognitive impairments. We have reviewed primary research in this area, noting that factors involved in the susceptibility and expression of PTSD symptoms are more complex and heterogeneous than is commonly stated, with extensive findings which are inconsistent with the stereotypic behavioral and biological profile of the PTSD patient. A thorough assessment of the literature indicates that interactions among myriad susceptibility factors, including social support, early life stress, sex, age, peri- and post-traumatic dissociation, cognitive appraisal of trauma, neuroendocrine abnormalities and gene polymorphisms, in conjunction with the inconsistent expression of the disorder across studies, confounds attempts to characterize PTSD as a monolithic disorder. Overall, our assessment of the literature addresses the great challenge in developing a behavioral and biomarker-based diagnosis of PTSD. Published by Elsevier Ltd.

    Municipal solid waste has seen increasing annual volumes for many decades in contemporary Europe and constitutes, if not properly managed, an environmental problem due to local pollution and greenhouse gas emissions. From an energy perspective, waste is also an alternative fuel for power and heat...... heat distribution infrastructures, without which no large-scale recovery and utilisation of excess heat is possible. In this paper, which aims to estimate municipal solid waste volumes available for heat recovery in European district heating systems in 2030, a literature and data review is performed...

  13. Research on road traffic noise and human health in India: Review of literature from 1991 to current

    2012-01-01

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

    Cardiac morbidity and mortality are closely related to cardiac volumes and global left ventricular (LV) function, expressed as left ventricular ejection fraction. Accurate assessment of these parameters is required for the prediction of prognosis in individual patients as well as in entire cohorts. The current standard of reference for left ventricular function is analysis by short-axis magnetic resonance imaging. In recent years, major extensive technological improvements have been achieved in computed tomography. The most marked development has been the introduction of the multidetector CT (MDCT), which has significantly improved temporal and spatial resolutions. In order to assess the current status of MDCT for analysis of LV function, the current available literature on this subject was reviewed. The data presented in this review indicate that the global left ventricular functional parameters measured by contemporary multi-detector row systems combined with adequate reconstruction algorithms and post-processing tools show a narrow diagnostic window and are interchangeable with those obtained by MRI.

    2012-03-01

    There is an ongoing controversy on the prevalence of primary aldosteronism (PA). We aimed to update a meta-analysis published in 2008, that compiled studies reporting the prevalence of positive ARR screening tests and PA. We therefore reviewed original studies published in 2008 or later to examine whether current reports provide similar, higher or lower prevalences of elevated ARRs or PA than reports included in the original meta-analysis. A systematic review of English articles using PubMed was conducted. Search and extraction of articles were performed by one review author; the second review author checked all extracted data. We identified 11 eligible studies. The updated, weighted mean prevalences of elevated ARRs and PA in primary care (prevalence of high ARRs 16.5%; prevalence of PA 4.3%) and referred patients (prevalence of high ARRs 19.6%; prevalence of PA 9.5%) were only marginally different from the mean values obtained in the original meta-analysis. Among the current studies the maximum values for the prevalence of elevated ARRs and PA were substantially lower than among the older studies. Our results confirm the main conclusions from the original meta-analysis. The prevalence of PA increases with the severity of hypertension and the inclusion of current study results did not alter the mean prevalences of elevated ARRs and PA in primary care and referred patients. Additionally, we found that current studies focus increasingly on patients in referral centers or special subgroups, while the prevalence of PA in the general hypertensive population is yet unknown.

    2015-07-01

    Full Text Available In comparison to other transportation modes, riding motorcycle is prone to accidents. Motorcyclists are more exposed to physical injury than the car drivers. Many multi-vehicle motorcycles crashes occur, there is right-of- way violation takes place in which another vehicle turns in fronts of a motorcycle, or a sudden cross of path of an on-coming motorcycle. One main factor which leads to high rate of motorcycle crashes is lack of conspicuity of motorcycles by other road users especially during day time traffic. This paper highlights previous studies on the implementation of motorcycle DRLs, focusing on the efficacy of the DRLs to improve motorcycle conspicuity. This paper reviews the impacts of DRL by motorcyclists on multi-vehicle motorcycle crash. The three categories of effects of motorcycle DRLs were reviewed. All literature, supporting that operating headlights during daytime appears to be an influential and effective approach to reduce rate of collision by improving motorcycle’s conspicuity in traffic. The motorcycle DRLs managed to reduce about 4 to 20% of motorcycle crash risk. This paper also recommends that motorcycle DRLs must be used globally, especially in countries with high motorcycle accidents to improve the safety of the riders as well as their pillion riders.

    Full Text Available Abstract Background Technological advances have enabled the widespread use of video cases via web-streaming and online download as an educational medium. The use of real subjects to demonstrate acute pathology should aid the education of health care professionals. However, the methodology by which this effect may be tested is not clear. Methods We undertook a literature review of major databases, found relevant articles relevant to using patient video cases as educational interventions, extracted the methodologies used and assessed these methods for internal and construct validity. Results A review of 2532 abstracts revealed 23 studies meeting the inclusion criteria and a final review of 18 of relevance. Medical students were the most commonly studied group (10 articles with a spread of learner satisfaction, knowledge and behaviour tested. Only two of the studies fulfilled defined criteria on achieving internal and construct validity. The heterogeneity of articles meant it was not possible to perform any meta-analysis. Conclusions Previous studies have not well classified which facet of training or educational outcome the study is aiming to explore and had poor internal and construct validity. Future research should aim to validate a particular outcome measure, preferably by reproducing previous work rather than adopting new methods. In particular cognitive processing enhancement, demonstrated in a number of the medical student studies, should be tested at a postgraduate level.

    2003-01-01

    The effectiveness of current approaches to workplace stress management for nurses was assessed through a systematic review. Seven randomised controlled trials and three prospective cohort studies assessing the effectiveness of a stress management programmes were identified and reviewed. The quality of research identified was weak. There is more evidence for the effectiveness of programmes based on providing personal support than environmental management to reduce stressors. However, since the number and quality of studies is low, the question as to which, if any, approach is more effective cannot be answered definitively. Further research is required before clear recommendations for the use of particular interventions for nursing work related stress can be made. PMID:12499451

    1998-03-01

    We reviewed toxicological studies, both experimental and epidemiological, that appeared in international literature in the period 1990-1997 and included both leaded and unleaded gasolines as well as their components and additives. The aim of this overview was to select, arrange, and present references of scientific papers published during the period under consideration and to summarize the data in order to give a comprehensive picture of the results of toxicological studies performed in laboratory animals (including carcinogenic, teratogenic, or embryotoxic activity), mutagenicity and genotoxic aspects in mammalian and bacterial systems, and epidemiological results obtained in humans in relation to gasoline exposure. This paper draws attention to the inherent difficulties in assessing with precision any potential adverse effects on health, that is, the risk of possible damage to man and his environment from gasoline. The difficulty of risk assessment still exists despite the fact that the studies examined are definitely more technically valid than those of earlier years. The uncertainty in overall risk determination from gasoline exposure also derives from the conflicting results of different studies, from the lack of a correct scientific approach in some studies, from the variable characteristics of the different gasoline mixtures, and from the difficulties of correctly handling potentially confounding variables related to lifestyle (e.g., cigarette smoking, drug use) or to preexisting pathological conditions. In this respect, this paper highlights the need for accurately assessing the conclusive explanations reported in scientific papers so as to avoid the spread of inaccurate or misleading information on gasoline toxicity in nonscientific papers and in mass-media messages.

    Interprofessional education (IPE) is designed to provide students from different health sectors with opportunities to work together to enhance future collaboration. The implementation of IPE activities is a current trend in various countries. This review exclusively targets IPE issues involving undergraduate health profession students and highlights various approaches in different regions. A total of 28 articles published in peer-reviewed journals between January 2012 and July 2015 were assessed to determine recent trends in IPE implementation. Nine main strategies were identified: simulation-based education programmes; rotations in rural and community settings; interprofessional training wards; patient-centred case studies; theme-centred workshops; student seminars; student-delivered lectures; health promotion activities; and interactive lectures in a common setting. Many of these institutions had not restricted themselves to a single strategy and supplemented these activities with additional teaching or learning methods. Recommendations gathered from these diverse approaches may assist the development of sustainable strategies for implementing IPE in undergraduate medical curricula.

  2. Adaptations of leptin, ghrelin or insulin during weight loss as predictors of weight regain: a review of current literature.

    2014-03-01

    Numerous laboratory studies involving both animal and human models indicate that weight loss induces changes in leptin, ghrelin and insulin sensitivity, which work to promote weight regain. It is unclear, however, whether these biological changes serve as a biomarker for predicting weight regain in free-living humans in which biological, behavioral and environmental factors are likely at play. We identified 12 studies published between January 1995 and December 2011 that reported changes in leptin, ghrelin or insulin during intentional weight loss with a follow-up period to assess regain. Two of the nine studies examining leptin suggested that larger decreases were associated with greater regain, three studies found the opposite (smaller decreases were associated with greater regain), whereas four studies found no significant relationship; none of the studies supported the hypothesis that increases in ghrelin during weight loss were associated with regain. One study suggested that improvements in insulin resistance were associated with weight gain, but five subsequent studies reported no association. Changes in leptin, ghrelin or insulin sensitivity, taken alone, are not sufficient to predict weight regain following weight loss in free-living humans. In future studies, it is important to include a combination of physiological, behavioral and environmental variables in order to identify subgroups at greatest risk of weight regain.

    The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than controls. Growth, development and cognitive function in assisted-conception children are similar to controls. The absolute risk of imprinting disorders after assisted reproduction is less than 1%. A direct link between assisted reproduction and health-related outcomes in assisted-conception children could not be established. Women undergoing assisted reproduction are often older, increasing the chances of obtaining abnormal gametes that may cause deviations in outcomes between assisted-conception and naturally conceived children. However, after taking into account these factors, it is not clear to what extent poorer outcomes are due to the assisted reproduction procedures themselves. Large-scale, multicentre, prospective epidemiological studies are needed to investigate this further and to confirm long-term health consequences in assisted-conception children. Assisted reproduction treatment is a general term used to describe methods of achieving pregnancy by artificial means and includes IVF and sperm implantation. The effect of assisted reproduction treatment on the health of children born using these artificial methods is not fully understood. In April 2011, fertility research experts met to give presentations based on research in this area and to look carefully at the evidence

    Hepatocellular carcinoma is the most common primary liver cancer and it represents the majority of cancer-related deaths in the world. More than 70% of patients present at an advanced stage, beyond potentially curative options. Ytrrium-90 selective internal radiation therapy (Y90-SIRT) with glass microspheres is rapidly gaining acceptance as a potential therapy for intermediate and advanced stage primary hepatocellular carcinoma and liver metastases. The technique involves delivery of Y90 infused glass microspheres via the hepatic arterial blood flow to the appropriate tumor. The liver tumor receives a highly concentrated radiation dose while sparing the healthy liver parenchyma due to its preferential blood supply from portal venous blood. There are two commercially available devices: TheraSphere® and SIR-Spheres®. Although, Y90-SIRT with glass microspheres improves median survival in patients with intermediate and advanced hepatocellular carcinoma and has the potential to downstage hepatocellular carcinoma so that the selected candidates meet the transplantable criteria, it has not gained widespread acceptance due to the lack of large randomized controlled trials. Currently, there are various clinical trials investigating the use of Y90-SIRT with glass microspheres for treatment of hepatocellular carcinoma and the outcomes of these trials may result in the incorporation of Y90-SIRT with glass microspheres into the treatment guidelines as a standard therapy option for patients with intermediate and advanced stage hepatocellular carcinoma.

    2015-01-01

    This article elucidates an integrative model of hypnosis that integrates social, cultural, cognitive, and neurophysiological variables at play both in and out of hypnosis and considers their dynamic interaction as determinants of the multifaceted experience of hypnosis. The roles of these variables are examined in the induction and suggestion stages of hypnosis, including how they are related to the experience of involuntariness, one of the hallmarks of hypnosis. It is suggested that studies of the modification of hypnotic suggestibility; cognitive flexibility; response sets and expectancies; the default-mode network; and the search for the neurophysiological correlates of hypnosis, more broadly, in conjunction with research on social psychological variables, hold much promise to further understanding of hypnosis.

Firstly, it points out the drawbacks and weaknesses of the 1st and 2nd phases of the development of this discipline, namely the positivist and non-positivist characteristic of influence study, and the lack of a "world mind" in parallel study by claiming that there's no comparability between different cultures. Secondly, the cultural diversity should be highlighted as comparability since we should not only seek the common ground but also pay attention to the differences. The variation theory in eomparative literature raised by the present author can help complete the theoretical system of comparative literature. Thirdly, this artiele points out that eom- parative literature will enter the phase of world literature, in which Chinese scholars will play an important role.

    The use of technetium-99m 2-methoxyisobutyl isonitrile ({sup 99m}Tc MIBI) for assistance in minimally invasive radioguided surgery (MIRS) is growing in popularity as a safe, effective, and proficient technique used for parathyroidectomy in primary hyperparathyroidism (PHPT) treatment. Previously, the preferred treatment for PHPT was bilateral neck exploration (BNE), a very invasive, costly, and lengthy procedure. However, as a large majority (80–85% of cases of PHPT) are attributed to a single parathyroid adenoma (PA), a simpler more direct technique such as MIRS is a far better option. The following article is an exploration of the current literature concerning varied protocols utilizing {sup 99m}Tc MIBI for assistance in MIRS for patients undergoing treatment of PHPT. This technique boasts many advantageous outcomes for patients suffering from PHPT. These include a reduction in cost, operating time, and patient recovery; less evidence of post-surgical hypocalcaemia, less pain, and complications; superior cosmetic results; same-day discharge; and the possibility of local anaesthesia which is particularly beneficial in elderly patients. Better outcomes for patients with deep or ectopic PAs, reduced intra-operative complications, and improved cosmetic outcomes for patients who have previously undergone thyroid and/or parathyroid surgery are also advantageous. Of the literature reviewed it was also found that no patients suffered any major surgical complications such as laryngeal nerve palsy or permanent hypoparathyroidism using {sup 99m}Tc MIBI for assistance in MIRS.

    Full Text Available With the rise of new technologies, citizens can contribute to scientific research via Web 2.0 applications for collecting and distributing geospatial data. Integrating local knowledge, personal experience and up-to-date geoinformation indicates a promising approach for the theoretical framework and the methods of natural hazard analysis. Our systematic literature review aims at identifying current research and directions for future research in terms of Volunteered Geographic Information (VGI within natural hazard analysis. Focusing on both the preparedness and mitigation phase results in eleven articles from two literature databases. A qualitative analysis for in-depth information extraction reveals auspicious approaches regarding community engagement and data fusion, but also important research gaps. Mainly based in Europe and North America, the analysed studies deal primarily with floods and forest fires, applying geodata collected by trained citizens who are improving their knowledge and making their own interpretations. Yet, there is still a lack of common scientific terms and concepts. Future research can use these findings for the adaptation of scientific models of natural hazard analysis in order to enable the fusion of data from technical sensors and VGI. The development of such general methods shall contribute to establishing the user integration into various contexts, such as natural hazard analysis.

    Full Text Available Background: Henoch-Schönlein purpura is the most common vasculitis of small blood vessels in children. The diagnosis of the disease is confirmed in a patient with a specific rash, joint inflamation, abdominal pain or renal disease. The specific rash is necesary for the confirmation of the diagnosis. Henoch-Schönlein purpura can rarely present with a complication withot a prior presentation of the rash. In these cases diagnosis is difficult until the presentation of the specific skin manifestation. In the majority of patients the disease course is not complicated and has a good prognosis.Conclusion: In this article we present three patients with an atypical presentation of the disease and a review of current literature on the topic.

    This literature review outlines the current issues and debates relating to the dental health of adults with drug dependence. The dental health of adults with illegal drug dependence (IDD) continues to be under debate throughout dental practice, and the most appropriate model of care suitable to meet the high complex needs of this client group remains uncertain. The study aims to review and critically analyze available research relating to the oral health effects of illegal drug misuse and the dental health needs and status of adults with drug dependence. Second, it aims to identify and critically evaluate current models of dental service/care delivery, including relevant best practice guidance and potential barriers to dental access for adults with IDD. The available literature pertaining to dental health and adults with drug dependence are systematically reviewed and critically analyzed and evaluated in order to execute a rigorous investigation. The oral effects along with general medical complications associated with IDD are increasingly being recognized. There are substantive negative effects of IDD on oral health, particularly for those with opioid dependence; therefore, these clients have high complex dental needs and low use of dental services. Adults with drug dependence comprise a group with special dental needs and therefore need greater access to dental care than most people due to their high level of need. A high awareness of the implications for oral health care for adults with drug dependence is essential. Dental professionals have a key role in supporting the rehabilitation of these patients from potentially severe or fatal addictions. There is a distinct lack of national policy and guidance relating specifically to adults with drug dependence, and therefore, problems persist. Key findings and recommendations are presented to enhance the development of dental services for adults with IDD.

    In this article, the Task Force on Student Outcomes Assessment of the American Dental Education Association's Commission on Change and Innovation in Dental Education describes the current status of student outcomes assessment in U.S. dental education. This review is divided into six sections. The first summarizes the literature on assessment of dental students' performance. Section two discusses catalysts, with a focus on problem-based learning, for development of new assessment methods, while the third section presents several resources and guides that can be used to inform selection of assessment techniques for various domains of competence. The fourth section describes the methodology and results of a 2008 survey of current assessment practices in U.S. dental schools. In the fifth section, findings from this survey are discussed within the context of competency-based education, the educational model for the predoctoral curriculum endorsed by the American Dental Education Association and prescribed by the Commission on Dental Accreditation. The article concludes with a summary of assessments recommended as optimal strategies to measure three components of professional competence based on the triangulation model. The survey of assessment practices in predoctoral education was completed by 931 course directors, representing 45 percent of course directors nationwide, from fifty-three of the fifty-six U.S. dental schools. Survey findings indicate that five traditional mainstays of student performance evaluation-multiple-choice testing, lab practicals, daily grades, clinical competency exams, and procedural requirements-still comprise the primary assessment tools in dental education. The survey revealed that a group of newer assessment techniques, although frequently identified as best practices in the literature and commonly used in other areas of health professions education, are rarely employed in predoctoral dental education.

    2013-03-01

    Clinicians are often asked by patients, "When can I drive again?" after lower limb injury or surgery. This question is difficult to answer in the absence of any guidelines. This review aims to collate the currently available evidence and discuss the factors that influence the decision to allow a patient to return to driving. Medline, Web of Science, Scopus, and EMBASE were searched using the following terms: 'brake reaction time', 'brake response time', 'braking force', 'brake pedal force', 'resume driving', 'rate of application of force', 'driving after injury', 'joint replacement and driving', and 'fracture and driving'. Of the relevant literature identified, most studies used the brake reaction time and total brake time as the outcome measures. Varying recovery periods were proposed based on the type and severity of injury or surgery. Surveys of the Driver and Vehicle Licensing Agency, the Police, insurance companies in the United Kingdom and Orthopaedic Surgeons offered a variety of opinions. There is currently insufficient evidence for any authoritative body to determine fitness to drive. The lack of guidance could result in patients being withheld from driving for longer than is necessary, or returning to driving while still unsafe.

    2017-01-01

     In 2009, the Japan Anti-Doping Agency (JADA) established the "Sports Pharmacist Accreditation Program" to prevent doping in sports. Since then, anti-doping activities in Japan have been attracting attention. In this study, we investigated research about the current status of doping from 2007 to 2014 in Japan to make anti-doping activities more concrete, and we also discussed future anti-doping activities by pharmacists. In Japan, bodybuilding was the sporting event with the highest number and rate of doping from 2007 to 2014. Many of the positive doping cases were detected for class S1 (anabolic agents), S5 (diuretics and masking agents), and S6 (stimulants). Within class S1, supplements were the main cause of positive doping. Within class S5, medicines prescribed by medical doctors were the main cause of positive doping. Within class S6, non-prescription medicines (e.g., OTC) were the main cause of positive doping. When we looked at the global statistics on doping, many of the positive doping cases were detected for class S1. On comparing the Japanese statistics with the global statistics, the rate of positive doping caused by class S1 was significantly lower, but that caused by classes S5 and S6 was significantly higher in Japan than in the world. In conclusion, pharmacists in Japan should pay attention to class S1, S5, and S6 prohibited substances and to the sport events of bodybuilding. Based on this study, sports pharmacists as well as common pharmacists should suggest new anti-doping activities to prevent doping in the future.

    1998-01-01

    Purpose of the study was to summarize the current scientific knowledge of the interaction between rehabilitative procedures and the periprosthetic bone remodeling processes in the early postoperative phase of total hip arthroplasties. In a comprehensive review of the international literature we analysed the interdependence between osseointegration, primary implant stability, relative micromotion of implant versus bone, and joint loading forces during mobilisation or physiotherapy. Accordingly, guidelines for the rehabilitation of cemented as well as cementless hip arthroplasties were established in order to eliminate factors disturbing prosthetic integration and hence provide for the best long-term stability of the implanted prosthesis possible. Osseointegration of cementless implants is impossible if relative micromotions exceed > 150 microns. Furthermore, torsional stresses (i.e. alternate climbing of stairs, rising from seated position without arm support) will destabilize uncemented femoral shaft implants. Cemented prostheses may be loaded with full body weight. Uncemented implants should be loaded only partially for at least 6 weeks. Loadings of the hip joint with more than twice the body-weight (i.e. walking without crutches, physical exercise against high resistances or long levers) are to be avoided for 3 months. The transition from the three-points walking to the two-points walking technique depends particularly on the conditions of the muscles stabilizing the hip joint. The rehabilitation of patients after total hip arthroplasty has to be brought into line with the changed biomechanical situation, the particulars of the implants and the individual requirements of the patients.

    2014-08-01

    Full Text Available Background: Attention deficit hyper activity disorder (ADHD is a developmental disorder, most often diagnosed in childhood, and characterized by hyperactivity and inattention that negatively impacts one's ability to function and fulfill social and personal obligations. Individuals with past history of ADHD may enlist in the military under certain conditions, however the full impact of military training and deployment of later in life ADHD symptoms is unclear. It is of particular interest how military experience may affect ADHD in remission and if such individuals might be at elevated risk for relapse of ADHD symptoms. Method: We performed a systematic review f the available literature including the Department of Defense (DOD guidelines for both eligibility to enlist and fitness for deployment based on reported history and current symptomatology of ADHD. Results: The after care for veterans with ADHD relapse is inconsistent and presents with number of challenges. We evaluate the DOD policies regarding the implications of ADHD for fitness for military service and post-combat mental health. Conclusion: The full extend of the interaction between pre-existing ADHD and post-combat PTSD are not fully understood. The development of comprehensive and clear algorithms for diagnosing and treating ADHD in the military before and after deployment will have a strong positive impact on the quality of care delivered to soldiers and veterans.

    Full Text Available Acinetobacter baumannii has emerged as a major cause of healthcare-associated infections. It commonly expresses clinical resistance to multiple antimicrobial agents, and hence, it is considered the paradigm of an extensively drug-resistant (XDR bacterium. XDR A. baumannii is a rapidly emerging pathogen, especially in the intensive care unit (ICU, causing nosocomial infections including sepsis, ventilatorassociated pneumonia, meningitis, peritonitis, urinary tract infection, and central venous catheter-related infection. In the present report, we described an in vivo evolution of A. baumannii strain from a colistinsusceptibility to a colistin-resistance state. A 65-year-old male, who suffered a duodenal ulcer, two days after hospitalization and during the stay in ICU, contracted a pneumonia and peritoneal infection by a carbapenem-resistant A. baumannii strain. After a combination treatment with colistin, vancomycin plus imipenem, and within seven days, the pathogen rapidly evolved in seven days to a pandrug-resistant phenotype. As the antimicrobial treatment was stopped, the A. baumannii isolate changed another time its profile to colistin, becoming newly susceptible, showing a very high level of adaptability to external conditions. We also have reviewed here the current literature on this worryingly public health threat.

    2011-02-01

    Streptomycin-resistant (Sm(R)) strains of the fire blight pathogen Erwinia amylovora were first isolated in southwest Michigan in 1991. Since that time, resistant strains have progressed northward to other apple-producing regions in the state. A total of 98.7% of Sm(R) strains isolated between 2003 and 2009 in Michigan harbored the strA-strB genes on transposon Tn5393. strA and strB encode phosphotransferase enzymes that modify streptomycin to a nonbactericidal form. Mutational resistance to streptomycin, caused by a point mutation-mediated target-site alteration of the ribosomal S12 protein, occurred in 1.3% of E. amylovora strains from Michigan. Tn5393 was originally introduced to E. amylovora on the plasmid pEa34; thus, the first Sm(R) strains isolated contained both pEa34 and the ubiquitous nonconjugative plasmid pEA29. More recently, we have observed Sm(R) strains in which Tn5393 is present on pEA29, suggesting that the transposon has moved via transposition from pEa34 to pEA29. Almost all of the strains containing Tn5393 on pEA29 had lost pEa34. Of 210 pEA29::Tn5393 plasmids examined, the transposon was inserted at either nucleotide position 1,515 or 17,527. Both of these positions were in noncoding regions of pEA29. Comparative sequencing of the housekeeping genes groEL and potentially variable sequences on pEA29 was done in an attempt to genetically distinguish Sm(R) strains from streptomycin-sensitive (Sm(S)) strains isolated in Michigan. Only 1 nucleotide difference within the total 2,660 bp sequenced from each strain was observed in 2 of 29 strains; multiple sequence differences were observed between the Michigan strains and E. amylovora control strains isolated in the western United States or from Rubus spp. Alterations in virulence observable using an immature pear fruit assay were detected in three of eight Sm(R) strains examined. Our current genetic data indicate that only two Sm(R) strain genotypes (strains containing pEA29::Tn5393 with Tn5393

    2016-12-01

    The aim of this study was to systematically review the literature on effect of initiating urate-lowering treatment (ULT) during an acute attack of gout on duration of index attack and persistence on ULT. OVID (Medline), EMBASE and AMED were searched to identify randomized controlled trials (RCTs) of ULT initiation during acute gout attack published in English language. Two reviewers appraised the study quality and extracted data independently. Standardized mean difference (SMD) and relative risk (RR) were used to pool continuous and categorical data. Meta-analysis was carried out using STATA version 14. A total of 537 studies were selected. A total of 487 titles and abstracts were reviewed after removing duplicates. Three RCTs were identified. There was evidence from two high-quality studies that early initiation of allopurinol did not increase pain severity at days 10-15 [SMDpooled (95 % CI) 0.18 (-0.58, 0.93)]. Data from three studies suggested that initiation of ULT during an acute attack of gout did not associate with dropouts [RRpooled (95 % CI) 1.16 (0.58, 2.31)]. There is moderate-quality evidence that the initiation of ULT during an acute attack of gout does not increase pain severity and risk of ULT discontinuation. Larger studies are required to confirm these findings so that patients with acute gout can be initiated on ULT with confidence.

    Apostoli, P; Sala, Emma

    2009-01-01

    in some sequences of the film "Modern Times" Chaplin is clearly involved in activities at high risk for work-related musculo-skeletal disorders of the upper extremities (UEWMSDs), but evidence and perception of any complaint are not evident. To evaluate the extent of the biomechanical risk using current risk assessment methods and discuss the possible reasons for lack of complaints. we made an analysis using six of the current methods for ergonomic risk assessment (State of Washington, check list OCRA, HAL by ACGIH, RULA Strain Index, OREGE). All the methods applied demonstrated high-to-very high levels of biomechanical risk for the upper extremities, with evident psychic effects but without apparent musculo-skeletal disorders. The discrepancy between evident psychological disorders ad apparent absence of UEWMSDs are discussed as being due to either: an artistic choice by Charlie Chaplin who focused on the aspects thought to be more immediately and easily comic; the short duration of the physical load exertion; or because of a different perception of muscular work and fatigue that was also typical until the 1970's and 1980's, which also confirmed the principles and practices of our preventive and medical disciplines at that time.

    Phenylketonuria is characterized by mutations in the Phe hydroxylase gene that leads to the accumulation of Phe in plasma and the brain. The standard of care for phenylketonuria is nutritional management with dietary restriction of Phe and the provision of sufficient protein and energy for growth and health maintenance. The protein requirement in children with phenylketonuria is empirically determined based upon phenylketonuria nutritional guidelines that are adjusted individually in response to biochemical markers and growth. We determined dietary protein requirements in children with phenylketonuria with the use of the indicator amino acid oxidation (IAAO) technique, with l-[1-(13)C]Leu as the indicator amino acid. Four children (2 males; 2 females) aged 9-18 y with phenylketonuria [mild hyperphenylalanemia (mHPA); 6-10 mg/dL (360-600 μmol/L)] were recruited to participate in ≥7 separate test protein intakes (range: 0.2-3.2 g ⋅ kg(-1) ⋅ d(-1)) with the IAAO protocol with the use of l-[1-(13)C]Leu followed by the collection of breath and urine samples over 8 h. The diets were isocaloric and provided energy at 1.7 times the resting energy expenditure. Protein was provided as a crystalline amino acid mixture based on an egg protein pattern, except Phe and Leu, which were maintained at a constant across intakes. Protein requirement was determined with the use of a 2-phase linear-regression crossover analysis of the rate of l-[1-(13)C]Leu tracer oxidation. The mean protein requirement was determined to be 1.85 g ⋅ kg(-1) ⋅ d(-1) (R(2) = 0.66; 95% CI: 1.37, 2.33). This result is substantially higher than the 2014 phenylketonuria recommendations (1.14-1.33 g ⋅ kg(-1) ⋅ d(-1); based on 120-140% above the current RDA for age). To our knowledge, this is the first study to directly define a quantitative requirement for protein intake in children with mHPA and indicates that current protein recommendations in children with phenylketonuria may be insufficient

    流通领域的数据统计对于产业自身发展和宏观经济预测都具有极其重要的价值。目前,我国流通统计指标体系已经基本形成,但其数据内容、来源及发布方式等仍有改进的必要。应当以接轨国际标准的行业分类为基础,在“大流通”视野中确定流通产业的行业范围,进而建立由共性指标、个性指标构成的有机统一的指标体系。同时,有必要梳理、协调政府及相关机构目前发布的数据内容,通过“云技术”实现统筹与整合。并且,要明晰数据的来源渠道、采集方式,将重复矛盾转变为差异互补。在这一过程中,应当充分挖掘经济普查数据的利用价值,发挥非官方机构的补充作用,使流通统计更加全面、透明,为问题导向的分析研究提供更好的支撑。%Statistics in distribution area is of great importance both for the development of industry and macroeconomic forecasts. Currently,the statistical indicator system has been basically formed,but improvement is still needed for its data contents,sources and publication methods. According to international standards,the industry scope of‘enlarged distribution system’should be determined,and based on industry classification,an organically consolidated indicator system which includes both common and special indicators should be built. Meanwhile,it is necessary to rearrange and coordinate the contents of the data currently published by government and related organizations,and an integration could be achieved by using the"cloud tech". The source and collection method of data should also be made clear,so as to change the situation of data publication from repeated or contradictory into differentiated and complementary. In this process,the value of economic census data should be cherished and the NGOs can also play a supplementary role,so that the statistics can be made more comprehensive and transparent,thus providing

    2015-09-01

    Full Text Available Investigations of cyberbullying are beginning to emerge in the scientific literature because of their implications for child and adolescent development. In particular, cyberbullying victimisation has been associated with similar negative consequences to traditional or face-to-face bullying such as lower academic achievement, anxiety, and sometimes even suicide. Research has also started to emerge investigating the impact of such incidences on the life of adults. The literature in this area has been steadily growing over the last decade and this review highlights the current situation in terms of relevant features and the psychological impact on victims. The selection process consisted of a comprehensive search that was conducted in January 2015 in the following databases: PsychInfo, ERIC, Web of Science and Medline. A total of 19 papers were included. We conclude with suggestions for online psychological treatment for victims and bullies as a means of coping with the distress caused from cyberbullying experiences.

    The role of muscle spasm is not a new concept in the genesis of pain. Botulinum neurotoxin type A (BoNTA) has been successfully employed in a variety of muscular and inflammatory conditions. The aim of our study was to review the published literature on the role of BoNTA injection of the pelvic floor muscle in the management of women with chronic pelvic pain (CPP). A systematic search of the literature published up to June 2012 on the use of BoNTA in the treatment of female pelvic floor muscle spasm was carried out using relevant search terms in MEDLINE and EMBASE databases. The results were limited to full-text English language articles. Relevant trials as well as relevant reviews were selected and analyzed by two independent reviewers. Five studies (2 case reports, 1 prospective pilot study, 1 retrospective study and 1 randomised double-blind placebo controlled study) were included in this systematic review. Overall, BoNTA has shown to be beneficial in relieving CPP related to pelvic floor spasm. The role of BoNTA as a treatment of CPP has been recognized for more than 10 years. Although data are still scarce preliminary results are encouraging. BoNTA is an attractive option for refractory CPP related to pelvic floor muscle spasm, but further studies using validated and reproducible outcome measures are needed, to establish its effectiveness, safeness, technique, optimal dosage, and duration of symptom relief.

    A framework within sexual and reproductive health is presented to understand the mental health issues of the population of lesbian, gay and bisexual (LGB) adolescents and young people. Different ways of understanding the nature of internalized homophobia were developed. On the other hand, in suicidology studies it is understood that the risk of suicide consists of the steps of ideation, planning and attempted suicide, and that there is an increased risk of suicide in the LGB population. Numerous factors have been associated with suicide risk in this population, one of the main internalized homophobia and other mental health problems. By means of a literature review, to establish the possible relationship between internalized homophobia and ideation and attempted suicide in the LGB population, as well as to identify the mental health problems associated to suicide risk in sexually diverse communities. Articles in English and Spanish, mainly within the last five years, were reviewed. They included articles in peer reviewed journals, and databases, such as Google Scholar, Redalyc, Byreme, Ovid, Science Direct, Taylor and Francis, MEDLINE, Scopus, PsycINFO, and Ebsco. It was found in the available literature that internalized homophobia is associated with suicide ideation and attempts in adults. A state of science of the major mental health problems associated with suicide risk in young LGB people reported contradictory findings. While some studies showed an association between depression, anxiety and distress and suicidal ideation and attempts, in others, the data do not allow such a conclusion. The theoretical framework presents the most important conceptualizations of suicide risk and emphasizes the social type. It identifies issues of suicide prevention, protective factors that contribute towards this, as well as elements of psychotherapy for LGB consultants. It concludes and discusses the importance of studying the sexually diverse as regards determining factors

    Full Text Available Sickle cell disease (SCD is an autosomal recessive hemoglobinopathy that causes significant morbidity and mortality related to chronic hemolytic anemia, vaso-occlusion, and resultant end-organ damage. Tobacco smoke exposure (TSE through secondhand smoke exposure in people with SCD of all ages and through primary smoking in adolescents and adults is associated with significantly increased morbidity, with increased rates of emergency department visits and hospitalizations for painful vaso-occlusive crises and acute chest syndrome (ACS. Secondhand smoke is also associated with pulmonary function abnormalities in children with SCD who are already at risk for pulmonary function abnormalities on the basis of SCD. TSE is emerging as one of the few modifiable risk factors of SCD. This review discusses the current state of the evidence with respect to TSE and SCD morbidity, discusses potential mechanisms, and highlights current gaps in the evidence and future research directions.

    2013-01-01

    Olfactory neuroblastoma (esthesioneuroblastoma) was first described by Berger and Luc in 1924. It is considered to be an uncommon malignancy of the nasal cavity. The tumor arises from the specialized sensory epithelial olfactory cells, normally situated at the upper part of the nasal cavity, including the superior nasal concha, the roof of the nose and the cribriform plate. The imaging modalities of choice are computed tomography (CT) and magnetic resonance imaging (MRI). Combination of surgery and radiotherapy (either conventional radiotherapy or stereotactic radiosurgery), with or without chemotherapy is considered to be the standard of care for primary site disease by the majority of researchers. Combined transfacial and neurosurgical conventional approaches are also adopted in many reported cases, mainly due to the endocranial extension and the close anatomic relationship of esthesioneuroblastomas with the ethmoid roof and cribriform plate. Recent literature supports that endoscopic resection correlates with similar oncologic control rates compared with conventional open surgery, provided that basic oncologic surgical principles with clearance of margins and intradural dissection (when required) are completely maintained.

    Kirschner, P

    2004-04-01

    There is still a controversial discussion in literature about the use of motor driven splints in knee surgery--as the principle of continuous passive motion, CPM. For this reason it seemed useful for an evaluation to look through the papers which were published since 1990. It was obvious, that negative results were published often before this year, but this papers are still quoted standard works. In medical data bases subito-doc.de, medscape.com, medica.de and zbmed.de 230 papers were found by search CPM, continuous passive motion and arthromot. Coincidentally there was a search for authors who were already quoted in other papers. 36 papers concerning CPM after knee surgery were utilized. The role of CPM regarding the range of motion, swelling, duration of hospital stay, use of analgesics, costs, postoperative manipulations, wound healing and thrombo embolic complications was evaluated. Although the results of this partial retrospective, partial prospective, sometimes randomized or double blinded studies are in contradiction, there can only be found a trend to better results. New clinical studies for evidence based guidelines in the handling of continuous passive motion after knee surgery are necessary.

    Abstract Our review of real-time three-dimensional echocardiography (RT3DE) discusses the diagnostic utility of RT3DE and provides a comparison with two-dimensional echocardiography (2DE) in clinical cardiology. A Pubmed literature search on RT3DE was performed using the following key words: transthoracic, two-dimensional, three-dimensional, real-time, and left ventricular (LV) function. Articles included perspective clinical studies and meta-analyses in the English language, and focused on the role of RT3DE in human subjects. Application of RT3DE includes analysis of the pericardium, right ventricular (RV) and LV cavities, wall motion, valvular disease, great vessels, congenital anomalies, and traumatic injury, such as myocardial contusion. RT3DE, through a transthoracic echocardiography (TTE), allows for increasingly accurate volume and valve motion assessment, estimated LV ejection fraction, and volume measurements. Chamber motion and LV mass approximation have been more accurately evaluated by RT3DE by improved inclusion of the third dimension and quantification of volumetric movement. Moreover, RT3DE was shown to have no statistical significance when comparing the ejection fractions of RT3DE to cardiac magnetic resonance (CMR). Analysis of RT3DE data sets of the LV endocardial exterior allows for the volume to be directly quantified for specific phases of the cardiac cycle, ranging from end systole to end diastole, eliminating error from wall motion abnormalities and asymmetrical left ventricles. RT3DE through TTE measures cardiac function with superior diagnostic accuracy in predicting LV mass, systolic function, along with LV and RV volume when compared with 2DE with comparable results to CMR.

    Full Text Available Lung cancer is the leading cause of cancer related morbidity and mortality worldwide. Currently, the vast majority of lung cancers are diagnosed at a late stage, when patients become symptomatic leading to dismal, less than 15% five-year survival rates. Evidence has demonstrated that screening computed tomography scans can be used to detect lung cancer, but these scans have high false positive rates. Therefore, there is a continued need for the development of minimally-invasive methods to screen the high risk population and diagnose lung cancer at an earlier, curable stage. One such promising area is the use micro-RNAs. These are short, non-coding RNA molecules that have been shown in previous research to be dysregulated in cancers. This review will focus on the potential use of miRNA levels in various biological fluids (whole blood, plasma, serum, and sputum and demonstrate their potential utility as screening and diagnostic biomarkers for lung cancer. Current research will be analyzed and compared, and future directions in establishing the use of miRNAs for detecting lung cancer will be discussed.

    Anderson, J C; Dubetz, C; Palace, V P

    2015-02-01

    Developed to replace organophosphate and carbamate insecticides, neonicotinoids are structurally similar to nicotine. The three main neonicotinoid insecticides, imidacloprid, clothianidin, and thiamethoxam, are being re-evaluated by Health Canada's Pest Management Regulatory Agency (PMRA). An important aspect of the re-evaluation is the potential for effects in non-target organisms, including aquatic organisms. Leaching into surface waters is one of the major concerns surrounding extensive use of neonicotinoids, especially in close proximity to water bodies. The PMRA has classified IMI as 'persistent' with a 'high' leaching potential. Globally, neonicotinoids have been detected in a variety of water bodies, typically at concentrations in the low μg/L range. While IMI has been included in some monitoring exercises, there are currently very few published data for the presence of CLO and THM in Canadian water bodies. The majority of neonicotinoid toxicity studies have been conducted with IMI due to its longer presence on the market and high prevalence of use. Aquatic insects are particularly vulnerable to neonicotinoids and chronic toxicity has been observed at concentrations of IMI below 1 μg/L. Acute toxicity has been reported at concentrations below 20 μg/L for the most sensitive species, including Hyalella azteca, ostracods, and Chironomus riparius. Fish, algae, amphibians, and molluscs are relatively insensitive to IMI. However, the biological effects of THM and CLO have not been as well explored. The Canadian interim water quality guideline for IMI is 0.23 μg/L, but there is currently insufficient use, fate, and toxicological information available to establish guidelines for CLO and THM. Based on concentrations of neonicotinoids reported in surface waters in Canada and globally, there is potential for aquatic invertebrates to be negatively impacted by neonicotinoids. Therefore, it is necessary to address knowledge gaps to inform decisions around guidelines

    Full Text Available Despite the definition of specific diagnostic criteria to identify radiologically isolated syndrome (RIS suggestive of multiple sclerosis, its natural history remains incompletely understood. We retrospectively analyzed a Brazilian cohort of 12 patients to clarify their features and to emphasize the role of imaging predictors in clinical conversion. We demonstrated that, although some individuals did not exhibit progression over a lengthy follow-up period (16.7%, most patients will progress clinically or radiologically in the initial years of the follow-up (83.3%. Infratentorial and spinal cord involvement, as well as the total number of lesions, were more relevant predictors of progression than gadolinium enhancement. Further studies remain necessary to define the risk of conversion in males and to clarify the cognitive abilities of RIS patients. This study may provide an improved understanding of the natural course and evolution of incidental magnetic resonance imaging lesions, and further assists with the management of RIS in clinical practice.

    The influence of predictors for recurrence in relation to recurrence-free survival was analyzed retrospectively in differentiated thyroid cancer (DTC) patients under 21 years of age who underwent primary surgical treatment and who had a pathological diagnosis of DTC between 1983 and 2012 at Fudan University Cancer Hospital. Recurrences were retrospectively analyzed using a Cox regression model for the hazard ratio (HR) according to the clinicopathological features. A meta-analysis was performed with respect to the potential predictors for recurrence from current related studies. In the present study, there were 146 young patients aged from 7 to 20 years, with a female/male ratio of 2.65/1. Female gender was the only factor significantly associated with recurrence according to univariate (HR = 2.812, P = 0.037) and multivariate (HR = 4.107, P = 0.024) Cox regression analyses. Meta-analyses revealed that multifocality (HR = 1.91, P < 0.05) and presentation at diagnosis (HR = 1.39, P < 0.05) were highly associated with recurrence in young DTC patients. However, female gender and other factors, such as age (≤10 vs. 11-20 years), PTC (PTC vs. FTC), extrathyroidal extension, lymph node metastasis, total thyroidectomy (total vs. less than total), radioiodine therapy, and radiation history, were not associated with recurrence in young DTC patients. In conclusion, multifocality and presentation at diagnosis are strong predictive factors of recurrence in relation to recurrence-free survival. We recommend studies with larger sample sizes and longer follow-up to verify the influence of predictors for disease recurrence in young patients.

    Wang Shuo's novels in a sense, to create a new fiction narrative mode, in order to cater to the public's kitsch sexual psychology, is one of the popular novels and a new writing mode of the popular contemporary literature development. Despite the mixed reviews and literary critics for“Wang Shuo Phenomenon", Wang Shuo's creation has a certain significance for the development of the current literature.%  王朔的小说创作在某种意义上创造了新的小说叙述模式,以迎合大众的“媚俗”性心理在社会上显示了它独特的价值,成为当时人们喜闻乐道的小说样式之一,也为当代通俗文学发展提供了新的书写模式。尽管文学界和评论界对于“王朔现象”的评论褒贬不一,但王朔的创作对于当下文学的发展具有一定的意义。

  8. Chronic Constipation: a Review of Current Literature.

    Sbahi, Hani; Cash, Brooks D

    2015-12-01

    Chronic constipation is a common health condition representing a substantial proportion of primary care visits and referrals to specialist providers. Chronic constipation can have a significant negative effect on health-related quality of life and has been associated with psychological distress in severely affected patients. It has the potential to cause patients to curtail work, school, and social activities. While different pathophysiological mechanisms have been implicated in the development of chronic constipation, in some instances, the causes of chronic constipation are not easily determined. Expenditures for the evaluation and management of chronic constipation represent a significant burden on patients and payers, and it is important for clinicians to have a clear understanding of the different pathophysiological mechanisms associated with constipation, understand the different testing modalities and treatments that are available including their appropriateness and limitations, and tailor that knowledge to the management of individual patients.

  9. Twenty-five-year-old Woman with Bilateral Borderline Ovarian Tumour Desiring to Preserve Fertility - Case Report and Literature Review on the Current State of Fertility Preservation in Women with Borderline Ovarian Tumours.

    Borderline ovarian tumours are semimalignant tumours occurring unilaterally or bilaterally with a peak incidence among women of reproductive age. Since the affected women often wish to preserve fertility, particular precautions must be taken when counselling the patient and obtaining consent prior to planning an individual treatment. Options for preserving fertility include an organ-sparing surgical procedure and cryopreservation of oocytes and/or ovarian tissue. In this article, we report on a 25-year-old patient with a bilateral seromucinous borderline tumour who desired all fertility-preserving options. In order to perform the procedure without delay, we opted to perform luteal phase stimulation prior to oocyte retrieval. We conclude by discussing the current literature on the state of fertility preservation in the treatment of borderline ovarian tumours.

    Study Objectives: Slow wave sleep (SWS) plays a critical role in body restoration and promotes brain plasticity; however, it markedly declines across the lifespan. Despite its importance, effective tools to increase SWS are rare. Here we tested whether a hypnotic suggestion to “sleep deeper” extends the amount of SWS. Design: Within-subject, placebo-controlled crossover design. Setting: Sleep laboratory at the University of Zurich, Switzerland. Participants: Seventy healthy females 23.27 ± 3.17 y. Intervention: Participants listened to an auditory text with hypnotic suggestions or a control tape before napping for 90 min while high-density electroencephalography was recorded. Measurements and Results: After participants listened to the hypnotic suggestion to “sleep deeper” subsequent SWS was increased by 81% and time spent awake was reduced by 67% (with the amount of SWS or wake in the control condition set to 100%). Other sleep stages remained unaffected. Additionally, slow wave activity was significantly enhanced after hypnotic suggestions. During the hypnotic tape, parietal theta power increases predicted the hypnosis-induced extension of SWS. Additional experiments confirmed that the beneficial effect of hypnotic suggestions on SWS was specific to the hypnotic suggestion and did not occur in low suggestible participants. Conclusions: Our results demonstrate the effectiveness of hypnotic suggestions to specifically increase the amount and duration of slow wave sleep (SWS) in a midday nap using objective measures of sleep in young, healthy, suggestible females. Hypnotic suggestions might be a successful tool with a lower risk of adverse side effects than pharmacological treatments to extend SWS also in clinical and elderly populations.

  19. [Suggestion and hypnosis in hysteria].

    Science.gov (United States)

    Berner, P

    1995-12-15

    Suggestive influences allow to resolve ambiguities. Normally they are only accepted if they correspond with the knowledge and believes of the subject. Under hypnosis or under the impact of serious psychic perturbations one may take up reality constructions which are not in conformity with these criteria. The restriction of consciousness and the ignoring of certain functions permitting this are the common basis of hypnosis and hysteria. But suggestions do not cause the later; they may only shape the symptomatology. Hypnosis can create a terrain facilitating the resolution of the problems underlying hysteria but it does not represent the treatment of hysteria.

    2004-01-01

    With some experience of teaching English in college behind me, I would like to make this paper a preliminary attempt to consider the study of literature from the perspective of English Language Teaching ( ELT). It is preliminary because this is an area which has been neglected in recent discussions of English teaching, while practice has continued to relate the two. Because this is a question which has been little discussed in relation to current English teaching theory, this paper will be essentially philosophical and discursive in approach. It will also attempt a consideration of approaches to literature teaching in principle, reduced to basic categories which may be helpful to teachers, in order to set in context the difficulties teachers meet with in ELT in China. Some constructive approaches are being discussed as well as some suggestions on improving literature teaching in ELT forwarded.

  5. Literature review :

    Energy Technology Data Exchange (ETDEWEB)

    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.

    In this paper we suggest a configuration of photons consistent with a spin $\\hbar$, and a configuration of the fermions coherent with a spin $\\hbar/2$. These suggested configurations open the way to further analyses which lead to the following conclusions: - There cannot exist elementary particles of spin $\\hbar/2$ with a mass inferior to $1m_e$ or with a radius greater than $1l_e$. - The electrostatic force derives from the centrifugal forces inherent to the spin and are propagated by photons. - The derivation of the electrostatic force explains the existence of positive and negative charges and Coulomb's law. - The enormous differences between the centrifugal forces and the centripetal forces at the surface of the protons give rise to quantic fluctuations of space which generate the energy flows necessary for equilibrium. These energy flows can explain gravitation and the strong force. - The mass of the proton, $m_p$, and the mass of the neutron, $m_n$, must each have a concrete value required for the cohes...

    To perform a systematic literature review as a basis for the update of the Assessment in SpondyloArthritis International Society and European League Against Reumatism (ASAS/EULAR) recommendations for the management of AS with non-pharmacological interventions and non-biologic drugs. The search was performed in PubMed, EMBASE, PEDro and Cochrane between 1 January 2005 and 1 December 2009, and in abstracts of EULAR and ACR meetings (2007-09). Effect sizes for outcomes on pain, disease activity, spinal mobility and physical function and level of evidence were presented. Of 2383 papers, 35 with complete data were included. Physical therapy exercises in various modalities have positive effects on BASFI, BASDAI, pain and mobility function. Various NSAIDs including coxibs improve BASDAI, disease activity and BASFI. No effect of SSZ and MTX on any variable was found. Surgical interventions of the spine and the hip can give excellent results by restoring function. This concise summary of current evidence for non-pharmacological interventions and non-biologic drugs formed the basis for the update of the ASAS/EULAR recommendations for the management of AS.

    Background: There were 1.2 million registered heroin users in China by the end of 2011, but little research in the country has focused on the neuropsychological functioning of these individuals.Aim: Assess error-related negativity (ERN) - an important indicator of high-level cognitive functioning - among males with heroin dependence undergoing rehabilitation.Method: Twenty male patients in a rehabilitation center who met DSM-IV criteria for heroin dependence and 15 healthy male controls completed 800 trials of Erikson flanker tasks to provoke ERN waves on the 32-electrode electroencephalograph (EEG) when erroneous responses are induced by presenting incongruent flankers around the target stimulus. Mean error rates and reaction times for the task, and the amplitude and latency of crude ERN waves and standardized ERN waves (created by subtracting the wave for correct responses from that for incorrect responses) at three frontal midline EEG electrodes (Fz, FCz, and Cz) were compared between patients and controls.Results: There was no significant difference in error rates between patients and controls but the reaction times for both erroneous and correct responses were shorter in patients than controls. The amplitude of both crude and standardized ERN waves was lower in patients than controls, but this difference became non-significant after adjustment for the lower educational level in the patient group. The latency of the peak value in both the crude and standardized ERN waves was significantly shorter in the patient group; this difference remained significant after adjustment for educational level. There was a significant correlation between the negative amplitude of the standardized ERN wave and the duration of heroin use.Conclusion: These findings suggest impaired impulse control and abnormal error-monitoring functions in persons with a history of heroin dependence and add to the growing literature on the neurological mechanisms related to cognitive dysfunction in

    Suggestions of limb paralysis in highly hypnotically suggestible subjects have been employed to successfully model conversion disorders, revealing similar patterns of brain activation associated with attempted movement of the affected limb. However, previous studies differ with regard to the executive regions involved during involuntary inhibition of the affected limb. This difference may have arisen as previous studies did not control for differences in hypnosis depth between conditions and/or include subjective measures to explore the experience of suggested paralysis. In the current study we employed functional magnetic resonance imaging (fMRI) to examine the functional anatomy of left and right upper limb movements in eight healthy subjects selected for high hypnotic suggestibility during (i) hypnosis (NORMAL) and (ii) attempted movement following additional left upper limb paralysis suggestions (PARALYSIS). Contrast of left upper limb motor function during NORMAL relative to PARALYSIS conditions revealed greater activation of contralateral M1/S1 and ipsilateral cerebellum, consistent with the engagement of these regions in the completion of movements. By contrast, two significant observations were noted in PARALYSIS relative to NORMAL conditions. In conjunction with reports of attempts to move the paralysed limb, greater supplementary motor area (SMA) activation was observed, a finding consistent with the role of SMA in motor intention and planning. The anterior cingulate cortex (ACC, BA 24) was also significantly more active in PARALYSIS relative to NORMAL conditions - suggesting that ACC (BA 24) may be implicated in involuntary, as well as voluntary inhibition of prepotent motor responses.

  12. A QUEST FOR LITERATURE IN ELT COURSEBOOKS

    Full Text Available The mission of literature in ELT has undergone a change for the last century. Once both a vehicle and an aim for teaching foreign language, literature now seems to remain out of center. Although it has various benefits for language learners, it reaches language classes only when the teacher is willing to make use of it, which is suggested by the studies conducted on teaching literature (Ross, 1991; Timuçin, 2001; Wang, 2009. Following the language teacher, coursebooks are the second primary input source in a classroom. In other words, if a teacher is reluctant to use literary texts in the lesson, the coursebook is the only provider for literature to be benefited. Therefore, this study aims at exploring to what extent literary texts and literary elements are used in ELT coursebooks. ELT coursebooks used in the preparatory schools of state universities in Ankara were analyzed for literary texts and elements. In addition, two ELT coursebook series which were published in the last 20 years and are not used anymore were analyzed in order to see whether ELT coursebooks differ with regard to the quantity of literary texts and elements in the last 20 years. In total, 22 coursebooks from different levels were analyzed. The finding reveals that ELT coursebooks contain bits and pieces of literature and there has been decrease in the number of literary texts in the currently used coursebooks.

    2010-12-27

    The concept of personality has recently begun to attract a great deal of interest in behavioural ecology. However, there is also a large and mature literature on personality within human psychology. These two bodies of work have developed independently and at present make rather little reference to one another. The current paper has two main objectives. First, we seek to acquaint behavioural ecologists with the principal ideas and issues found in the human personality psychology literature. Second, we explore how ideas from the behavioural ecology literature might help advance research in human personality psychology. We suggest strong potential for convergence between the two literatures in the near future. Common themes of this future unified science of personality include the conception of personality traits as reaction norms, a commitment to the importance of direct measurement of behaviour, investigation of both proximate and ultimate explanations for personality variation, and a concern with the impact of personality variation on survival and reproductive success.

    Full Text Available Few research studies have been conducted on the interpreter’s role in a Science Centre. Although the importance of this role is always stressed by museum practitioners, it seems that anecdotal evidence is the main source of information on this theme. The experience of a visitor in a Science Centre as well as in other museums has, among other things, well defined social dimensions. These dimensions are crucial in determining the quality and enjoyment of a visitor’s experience. There is evidence that suggests visitors go to a museum to meet others. Among the people that visitors meet in a Science Centre are interpreters, who help them not only to use and understand the exhibits but also to become familiar with a new environment. The following sections will illustrate what research studies say about interpreters, considering their twofold relation with visitors and exhibit developers.

  9. Teaching Skills through Literature

    Saleh Ahmed Saif Abdulmughni

    2016-03-01

    constitute a challenge to break through the cordon of words that are generally ambiguous that provides an appropriate exposure to the complex patterns of language. Literature entails both the ambiguity of thoughts and the diversity of linguistic representations and therefore it is pertinent to stick to the teaching of literature as a means of decoding the language. It raises the range of vocabulary and the canvass of thoughts. If a novel is picked up for evaluation, the first task is the evaluation of the time background to suggest the socio-political tendencies, the words which are not commonly used, and the thoughts that are dressed in a highly complex form call for a more detailed engagement with the text. This is the best and perhaps the most effective way to develop the vocabulary, phrases, the stock of words, complex structures and the pieces of information compressed in a symbolic form. A novel is a document of thought expressed at a particular period and the language used can be extremely useful for the communication purposes even though they are words by the highly trained and proficient minds. However no literature can ever be seen in isolation from the language as 'language is culture'. Without a judicious selection of text the learner will be at a loss to understand the conflicting usage of language for the meaning of the word is not determined by the word alone, rather it is the context which determines its meaning. What can aid a learner, further, is the quality of mind in finding a method to respond to the situation as the teacher has their own limitations, and it will be difficult for a teacher to explain without a moderate exposure to the language or literature.

  10. Employee suggestion programs: the rewards of involvement.

    Mishra, J M; McKendall, M

    1993-09-01

    Successful ESPs are the products of a great deal of effort by managers, administrators, teams, individuals, and reviewers, who are all striving to achieve the goals of increased profitability and enhanced employee involvement. A review of the literature indicates that there are several prescriptions that will increase the likelihood of a successful ESP (see the box). Today's American business prophets sound ceaseless calls to arms in the name of "world class performance," "global competitiveness," "total quality management," and a variety of other buzz terms. A burgeoning industry has evolved that promises, through speeches, teleconferences, seminars, and consulting contracts, to teach American organizations how to achieve excellence. In the face of a sputtering economy and unrelenting competitive pressure, today's managers must translate these laudatory ideals into hands-on reality without sacrificing the firm's profit margin to experimentation. If any idea can help an organization achieve improvement through a workable program, then that idea and that program deserve real consideration. An ESP represents an opportunity to tap the intelligence and resourcefulness of an organization's employees, and by doing so, reap significant cost savings. Those companies and managers that have an ESP program uniformly list economic advantages first when describing the benefits of their employee suggestion programs. But there is another deeper and longer term benefit inherent in an ESP. These programs allow employees to become involved in their organization; they drive deaccession to lower levels, they give employees more responsibility, they foster creative approaches to work, and they encourage creativity in pursuit of company goals.(ABSTRACT TRUNCATED AT 250 WORDS)

    Eleven collagen peptide sequences recovered from chemical extracts of dinosaur bones were mapped onto molecular models of the vertebrate collagen fibril derived from extant taxa. The dinosaur peptides localized to fibril regions protected by the close packing of collagen molecules, and contained few acidic amino acids. Four peptides mapped to collagen regions crucial for cell-collagen interactions and tissue development. Dinosaur peptides were not represented in more exposed parts of the collagen fibril or regions mediating intermolecular cross-linking. Thus functionally significant regions of collagen fibrils that are physically shielded within the fibril may be preferentially preserved in fossils. These results show empirically that structure-function relationships at the molecular level could contribute to selective preservation in fossilized vertebrate remains across geological time, suggest a 'preservation motif', and bolster current concepts linking collagen structure to biological function. This non-random distribution supports the hypothesis that the peptides are produced by the extinct organisms and suggests a chemical mechanism for survival.

    Analyzed on the characteristics of the current pebrine inspection of mother moth of F1 Hybrid, and proposed some suggest improvements about the pebrine inspection of mother moth of F1 Hybrid which suit for the silkworm eggs on card.Used the hypergeometric distribution as the basic mathematical model, to make compara-tive analysis of the current pebrine inspection of mother moth of F1 Hybrid with sampling inspection principle. There are some advantages for agricultural industry standard of silkworm loose eggs that the unqualified batch are rejected with high probability and less inspection works, but it also has some disadvantages that the qualified batch are rejected with high probability, the risk of manufacturer are great. Another standard is agricultural in-dustry standard of silkworm eggs on card, it has some advantages, including that the sampling are simple and practicable, the sample are typical, the unit is unified, the unqualified batch of silkworm eggs are rejected in the right number, and there also are some disadvantages that the inspection probability has no guarantee, the probability of “two types of errors” are coexist, workload of inspection are heavy. The regional industry standard of Guangxi has the features of agricultural industry standard of silkworm loose eggs, but also has some disadvantages that the implementation of standard is not asymmetric, the sample is not typical and the risk of manufacturer is further increased. Therefore, we put forward a fitting scheme and suggestions for actual produc-tion of silkworm eggs on card, including that stratified sampling, testing two times, controlled inspection risk, increased individual number in sampling group, groups as unit and the 1% index of percentage of dis-eased moths, etc.%分析现行桑蚕一代杂交种母蛾微粒子病检验方案的特点,提出适合平附种的母蛾微粒子病检验方案的改进意见。以超几何分布为基本数学模型,从抽样检验原理对桑

    2012-09-01

    Full Text Available Background The constantly growing publication rate of medical research articles puts increasing pressure on medical specialists who need to be aware of the recent developments in their field. The currently used literature retrieval systems allow researchers to find specific papers; however the search task is still repetitive and time-consuming. Aims In this paper we describe a system that retrieves medical publications by automatically generating queries based on data from an electronic patient record. This allows the doctor to focus on medical issues and provide an improved service to the patient, with higher confidence that it is underpinned by current research. Method Our research prototype automatically generates query terms based on the patient record and adds weight factors for each term. Currently the patient’s age is taken into account with a fuzzy logic derived weight, and terms describing blood-related anomalies are derived from recent blood test results. Conditionally selected homonyms are used for query expansion. The query retrieves matching records from a local index of PubMed publications and displays results in descending relevance for the given patient. Recent publications are clearly highlighted for instant recognition by the researcher. Results Nine medical specialists from the Royal Adelaide Hospital evaluated the system and submitted pre-trial and post-trial questionnaires. Throughout the study we received positive feedback as doctors felt the support provided by the prototype was useful, and which they would like to use in their daily routine. Conclusion By supporting the time-consuming task of query formulation and iterative modification as well as by presenting the search results in order of relevance for the specific patient, literature retrieval becomes part of the daily workflow of busy professionals.

    Full Text Available According to the Advanced Trauma Life Support recommendations for managing patients with life-threatening injuries, securing the airway is the first task of a primary caregiver. Airway management of patients with maxillofacial trauma is complex and crucial because it can dictate a patient’s survival. Securing the airway of patients with maxillofacial trauma is often extremely difficult because the trauma involves the patient’s airway and their breathing is compromised. In these patients, mask ventilation and endotracheal intubation are anticipated to be difficult. Additionally, some of these patients may not yet have been cleared of a cervical spine injury, and all are regarded as having a full stomach and having an increased risk of regurgitation and pulmonary aspiration. The requirements of the intended maxillofacial operation may often preclude the use of an oral intubation tube, and alternative methods for securing the airway should be considered before the start of the surgery. In order to improve the clinical outcome of patients with maxillofacial trauma, cooperation between maxillofacial surgeons, anesthesiologists, and trauma specialists is needed. In this review, we discuss the complexity and difficulties of securing the airway of patients with maxillofacial trauma and present our approach for airway management of such patients.

    2016-10-01

    Full Text Available Background Laparoscopic rectal cancer surgery offers several advantages over open surgery, including quicker recovery, shorter hospital stay and improved cosmesis. However, laparoscopic rectal surgery is technically difficult and is associated with a long learning curve. The last decade has seen the emergence of robotic rectal cancer surgery. In contrast to laparoscopy, robotic surgery offers stable 3D views with advanced dexterity and ergonomics in narrow spaces such as the pelvis. Whether this translates into a shorter learning curve is still debated. The aim of this literature search is to ascertain the learning curve of robotic rectal cancer surgery. Methods This review analyses the literature investigating the learning curve of robotic rectal cancer surgery. Using the Medline database a literature search of articles investigating the learning curve of robotic rectal surgery was performed. All relevant articles were included. Results Twelve original studies fulfilled the inclusion criteria. The current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. Conclusions There are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and outcome reporting. Nevertheless, current evidence suggests that robotic rectal surgery might be easier to learn than laparoscopy. Further well designed studies applying CUSSUM analysis are required to validate this motion.

  10. Sources of error in the retracted scientific literature

    Science.gov (United States)

    Casadevall, Arturo; Steen, R. Grant; Fang, Ferric C.

    2014-01-01

    Retraction of flawed articles is an important mechanism for correction of the scientific literature. We recently reported that the majority of retractions are associated with scientific misconduct. In the current study, we focused on the subset of retractions for which no misconduct was identified, in order to identify the major causes of error. Analysis of the retraction notices for 423 articles indexed in PubMed revealed that the most common causes of error-related retraction are laboratory errors, analytical errors, and irreproducible results. The most common laboratory errors are contamination and problems relating to molecular biology procedures (e.g., sequencing, cloning). Retractions due to contamination were more common in the past, whereas analytical errors are now increasing in frequency. A number of publications that have not been retracted despite being shown to contain significant errors suggest that barriers to retraction may impede correction of the literature. In particular, few cases of retraction due to cell line contamination were found despite recognition that this problem has affected numerous publications. An understanding of the errors leading to retraction can guide practices to improve laboratory research and the integrity of the scientific literature. Perhaps most important, our analysis has identified major problems in the mechanisms used to rectify the scientific literature and suggests a need for action by the scientific community to adopt protocols that ensure the integrity of the publication process.—Casadevall, A., Steen, R.

  17. Suggestibility and negative priming: two replication studies.

    Science.gov (United States)

    David, Daniel; Brown, Richard J

    2002-07-01

    Research suggests that inhibiting the effect of irrelevant stimuli on subsequent thought and action (cognitive inhibition) may be an important component of suggestibility. Two small correlation studies were conducted to address the relationship between different aspects of suggestibility and individual differences in cognitive inhibition, operationalized as the degree of negative priming generated by to-be-ignored stimuli in a semantic categorization task. The first study found significant positive correlations between negative priming, hypnotic suggestibility, and creative imagination; a significant negative correlation was obtained between negative priming and interrogative suggestibility, demonstrating the discriminant validity of the study results. The second study replicated the correlation between negative priming and hypnotic suggestibility, using a different suggestibility measurement procedure that assessed subjective experience and hypnotic involuntariness as well as objective responses to suggestions. These studies support the notion that the ability to engage in cognitive inhibition may be an important component of hypnotic responsivity and maybe of other forms of suggestibility.

    Full Text Available Abstract Background Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and treatment. Method A search of Pubmed was carried out using the term 'umblic*' and 'metastases' or metastasis' revealed no references. Another search was made using the term "Sister Joseph's nodule" or sister Joseph nodule" that revealed 99 references. Of these there were 14 review articles, however when the search was limited to English language it yielded only 20 articles. Articles selected from these form the basis of this report along with cross references. Results The primary lesions usually arise from gastrointestinal or genitourinary tract malignancies and may be the presenting symptom or sign of a primary tumour in an unknown site. Conclusion A careful evaluation of all umbilical lesions, including an early biopsy if appropriate, is recommended. Recent studies suggest an aggressive surgical approach combined with chemotherapy for such patients may improve survival.

    Google Suggest is a service incorporated within Google Web Search which was created to help user find the right search phrase by proposing the autocompleting popular phrases while typing. The paper presents a new network steganography method called StegSuggest which utilizes suggestions generated by Google Suggest as a hidden data carrier. The detailed description of the method's idea is backed up with the analysis of the network traffic generated by the Google Suggest to prove its feasibility. The traffic analysis was also performed to discover the occurrence of two TCP options: Window Scale and Timestamp which StegSuggest uses to operate. Estimation of method steganographic bandwidth proves that it is possible to insert 100 bits of steganogram into every suggestions list sent by Google Suggest service.

    Full Text Available Iread with great interest Rashid and Rafiq's article published in the spring issue of this journal(1. The authors not only highlighted the shortcomings of the current hepatitis B vaccination strategy in Bangladesh but also prescribed awonderful policy, which is felt to be both costeffective and befitting with the country's existing programme on immunization. To complement thisI would like to add few more points: ||l|| Most neonates mount an immune response, which is believed to be adequate to reduce their risk of perinatal Hepatitis B Virus (HBV acquisition after vaccination(2. Though the pre-term babies (<37 weeks show a slower response than the term (||“||37 weeks babies, immunogenicity, which is inversely proportional to the gestational age, can be improved by increasing the vaccine dosage (2,3. l| Timing first dose of hepatitis B vaccine with BCG probably has a positive interaction: administration of BCG at the time of HBV vaccine priming at birth markedly increases the cytokines as well as ntibody responses to HBV vaccine(4. This astonishing finding might suggest that BCG has a synergistic effect on hepatitis B vaccination. Bangladesh is reported to have a very high (94% coverage of BCG vaccine(5; the uptake of HBV vaccine can be equally improved by timing it with BCG.l| The present infant vaccination policy will leave adolescents unguarded and hence nationwide prevention of the disease will be delayed. A recent survey unveils that available infrastructure in Bangladesh has sufficient spare capacity to sustain storage of an increased quantity of vaccines(5. To make good use of this unused legroom adolescent vaccination should be started along with infant vaccination. Countries such as Spain and Portugal have both neonatal and adolescent vaccination programmes in place, since 1993 and 2000 respectively, and these countries will be able to end the adolescent programme once the first immunised newborn cohort has reached the target age of the

    Full Text Available Physical barriers may hamper persons with disabilities (PWDs movement in built environment. The needs of physical barrier- free environment are internationally acknowledged. This study explores the Malaysian scenario on access and facilities for PWDs by reviewing relevant legislation and guidelines, and literatures that examined the access and facilities provided in public buildings. This study identifies that Malaysia has plays its roles by establishing the relevant acts and legislation on PWDs needs and requirements. Nevertheless, previous studies on PWDs in Malaysia, demonstrated that there are still lacking on the implementation of the practice towards the acts and legislations. This study suggests that the application of the acts and legislation should be comprehensive covering all types of public buildings in Malaysia. In addition, enforcement by the local authorities and government agencies is crucial in order to successfully creating a barrier-free environment for all.

    Full Text Available Although the topic of study relates to an environmental/health issue, it is the methodology described which serves to showcase an embryonic form of a new “more intelligent” protocol of search algorithm. Through the implementation of this algorithm, an extensive automated literature base yielded a single credible solution to a previously unsolved problem. Faced with a distressing but entirely unexplained incidence of birth defects, the proposed model of knowledge scavenging worked through acknowledged gaps in understanding of increased (phosphate fertilizer, enabled the template of known facts regarding the interactions of phosphates with the processes of mammal (and other animal growth, of metabolic function, and of neurological development, and delivered a causal model which would not, at least not easily, derive from current literature search methods. Illustrating the practical value of a step forwards in the design of intelligent literature search, the present study provides a candidate cause to explain a cluster of bovine deformity

  10. First Case of Trichoderma longibrachiatum CIED (Cardiac Implantable Electronic Device)-Associated Endocarditis in a Non-immunocompromised Host: Biofilm Removal and Diagnostic Problems in the Light of the Current Literature.

    2016-04-01

    Trichoderma species are saprophytic filamentous fungi producing localized and invasive infections that are cause of morbidity and mortality, especially in immunocompromised patients, causing up to 53% mortality. Non-immunocompromised patients, undergoing continuous ambulatory peritoneal dialysis, are other targets of this fungus. Current molecular diagnostic tools, based on the barcode marker ITS, fail to discriminate these fungi at the species level, further increasing the difficulty associated with these infections and their generally poor prognosis. We report on the first case of endocarditis infection caused by Trichoderma longibrachiatum in a 30-year-old man. This patient underwent the implantation of an implantable cardioverter defibrillator in 2006, replaced in 2012. Two years later, the patient developed fever, treated successfully with amoxicillin followed by ciprofloxacin, but an echocardiogram showed large vegetation onto the ventricular lead. After CIED extraction, the patient had high-grade fever. The culturing of the catheter tip was positive only in samples deriving from sonication according to the 2014 ESCMID guidelines, whereas the simple washing failed to remove the biofilm cells from the plastic surface. Subsequent molecular (ITS sequencing) and microbiological (macromorphology) analyses showed that the vegetation was due to T. longibrachiatum. This report showed that T. longibrachiatum is an effective threat and that sonication is necessary for the culturing of vegetations from plastic surfaces. Limitations of the current barcode marker ITS, and the long procedures required by a multistep approach, call for the development of rapid monophasic tests.

    2015-01-01

    Hypnotizability influences the development of false memories. In Experiment 1, participants heard a positive or negative suggestion regarding hypnosis and then listened to 8 Deese-Roediger-McDermott (DRM) false memory paradigm lists in a hypnotic state. Neither hypnosis nor prehypnotic suggestion affected memory. Highly hypnotizable participants were more accurate in recall and recognition. In Experiment 2, suggestions were delivered in the form of feedback. Participants heard a positive or negative suggestion about their performance prior to either the encoding or retrieval of 8 DRM lists. Neither accurate nor false memories were affected by the suggestion. Highly hypnotizable individuals recognized fewer critical lures if they received a negative suggestion about their performance. These results highlight the unusual role of hypnotizability in the creation of false memories.

    2015-03-01

    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.

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

  10. LSD enhances suggestibility in healthy volunteers.

    Carhart-Harris, R L; Kaelen, M; Whalley, M G; Bolstridge, M; Feilding, A; Nutt, D J

    2015-02-01

    Lysergic acid diethylamide (LSD) has a history of use as a psychotherapeutic aid in the treatment of mood disorders and addiction, and it was also explored as an enhancer of mind control. The present study sought to test the effect of LSD on suggestibility in a modern research study. Ten healthy volunteers were administered with intravenous (i.v.) LSD (40-80 μg) in a within-subject placebo-controlled design. Suggestibility and cued mental imagery were assessed using the Creative Imagination Scale (CIS) and a mental imagery test (MIT). CIS and MIT items were split into two versions (A and B), balanced for 'efficacy' (i.e. A ≈ B) and counterbalanced across conditions (i.e. 50 % completed version 'A' under LSD). The MIT and CIS were issued 110 and 140 min, respectively, post-infusion, corresponding with the peak drug effects. Volunteers gave significantly higher ratings for the CIS (p = 0.018), but not the MIT (p = 0.11), after LSD than placebo. The magnitude of suggestibility enhancement under LSD was positively correlated with trait conscientiousness measured at baseline (p = 0.0005). These results imply that the influence of suggestion is enhanced by LSD. Enhanced suggestibility under LSD may have implications for its use as an adjunct to psychotherapy, where suggestibility plays a major role. That cued imagery was unaffected by LSD implies that suggestions must be of a sufficient duration and level of detail to be enhanced by the drug. The results also imply that individuals with high trait conscientiousness are especially sensitive to the suggestibility-enhancing effects of LSD.

    2013-06-01

    Hypnotic responding might be due to attenuated frontal lobe functioning after the hypnotic induction. Little is known about whether personality traits linked with frontal functioning are associated with responsiveness to hypnotic suggestions. We assessed whether hypnotic suggestibility is related to the traits of self-control and impulsivity in 154 participants who completed the Brief Self-Control Scale, the Self-Regulation Scale, the Barratt Impulsiveness Scale (BIS-11), and the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A). BIS-11 non-planning impulsivity correlated positively with HGSHS:A (Bonferroni-corrected). Furthermore, in the best model emerging from a stepwise multiple regression, both non-planning impulsivity and self-control positively predicted hypnotic suggestibility, and there was an interaction of BIS-11 motor impulsivity with gender. For men only, motor impulsivity tended to predict hypnotic suggestibility. Hypnotic suggestibility is associated with personality traits linked with frontal functioning, and hypnotic responding in men and women might differ. Copyright © 2013 Elsevier Inc.

    2012-01-01

    The most frequent cause of failure after total hip replacement in all reported arthroplasty registries is peri-prosthetic osteolysis. Osteolysis is an active biological process initiated in response to wear debris. The eventual response to this process is the activation of macrophages and loss of bone. Activation of macrophages initiates a complex biological cascade resulting in the final common pathway of an increase in osteolytic activity. The biological initiators, mechanisms for and regulation of this process are beginning to be understood. This article explores current concepts in the causes of, and underlying biological mechanism resulting in peri-prosthetic osteolysis, reviewing the current basic science and clinical literature surrounding the topic.

    Science.gov (United States)

    Wignall, Nicholas D; Brown, E Sherwood

    2014-07-01

    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. To review the literature on citicoline's use in addictive disorders. Using PubMed we conducted a narrative review of the clinical literature on citicoline related to addictive disorders from the years 1900-2013 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. 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. 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.

    2007-10-15

    Breast conservation surgery followed by external beam radiotherapy to breast has become the standard of care in management of early carcinoma breast. A boost to the tumour bed after whole breast radiotherapy is employed in view of the pattern of tumour bed recurrences in the index quadrant and was particularly considered in patients with some adverse histopathological characteristics such as positive margins, extensive intraductal carcinoma (EIC), lymphovascular invasion (LVI), etc. There is however, now, a conclusive evidence of improvement in local control rates after a boost radiotherapy dose in patients even without such factors and for all age groups. The maximum absolute reduction of local recurrences by the addition of boost is especially seen in young premenopausal patients. At the same time, the addition of boost is associated with increased risk of worsening of cosmesis and no clear cut survival advantage. Radiological modalities such as fluoroscopy, ultrasound and CT scan have aided in accurate delineation of tumour bed with increasing efficacy. A widespread application of these techniques might ultimately translate into improved local control with minimal cosmetic deficit. The present article discusses the role of radiotherapy boost and the means to delineate and deliver the same, identify the high risk group, optimal technique and the doses and fractionations to be used. It also discusses the extent of adverse cosmetic outcome after boost delivery, means to minimise it and relevance of tumour bed in present day scenario of advanced radiotherapy delivery techniques like (IMRT)

    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.

  2. Simple nonlinear models suggest variable star universality

    2015-01-01

    Dramatically improved data from observatories like the CoRoT and Kepler spacecraft have recently facilitated nonlinear time series analysis and phenomenological modeling of variable stars, including the search for strange (aka fractal) or chaotic dynamics. We recently argued [Lindner et al., Phys. Rev. Lett. 114 (2015) 054101] that the Kepler data includes "golden" stars, whose luminosities vary quasiperiodically with two frequencies nearly in the golden ratio, and whose secondary frequencies exhibit power-law scaling with exponent near -1.5, suggesting strange nonchaotic dynamics and singular spectra. Here we use a series of phenomenological models to make plausible the connection between golden stars and fractal spectra. We thereby suggest that at least some features of variable star dynamics reflect universal nonlinear phenomena common to even simple systems.

    Spanish histologist Santiago Ramón y Cajal, one of the most notable figures in Neuroscience, and winner, along with Camillo Golgi, of the 1906 Nobel Prize in Physiology or Medicine for his discoveries on the structure of the nervous system, did not escape experimenting with some of the psychiatric techniques available at the time, mainly hypnotic suggestion, albeit briefly. While a physician in his thirties, Cajal published a short article under the title, "Pains of labour considerably attenuated by hypnotic suggestion" in Gaceta Médica Catalana. That study may be Cajal's only documented case in the field of experimental psychology. We here provide an English translation of the original Spanish text, placing it historically within Cajal's involvement with some of the key scientific and philosophical issues at the time.

    In the traditional translation teaching mode, the teacher is the main body of classroom, the teachers often explain too much and give few opportunities to students to practice. Even in terms of observation and evaluation of translation, it is also basically teacher-centered, so there is rare opportunity and time for students to debate and to express their own views. So the author gives some suggestions on solving this problem.

    This paper presents a review of the literature into dissociative identity disorder. This disorder, previously known as multiple personality disorder, is increasingly diagnosed, in part because of more focused diagnostic tools, but also because people are accessing services to assist with the longterm problems of early child abuse and neglect. Dissociative identity disorder is examined in the literature according to a variety of discourses, each of which suggest different ways of conceptualizing problems and therapeutic approaches. These discourses reviewed include: psychiatry, psychology, corporeality, feminism, social constructivism, anthropology, and postmodernism. The paper concludes with an examination of the nursing literature and suggests opportunities for nursing research into this complex mental health problem.

    Plagiarism causes a serious concern in scientific literature. I distinguish two types of plagiarism. What is routinely highlighted and discussed is the reprehensible type of stealing another author's ideas and words. This type I categorize as "heterotrophic" plagiarism. A more prevalent and less-discussed type of plagiarism is the verbatim use of same sentences repetitively by authors in their publications. This I categorize as "autotrophic" plagiarism. Though harmless per se, autotrophic plagiarism is equally taxing on the readers. The occurrence of autotrophic plagiarism is mainly caused by the lack of proficiency in the current lingua franca of science, ie, English. The writings of 22 Nobel literature laureates who wrote in English, especially their travelogues, essays, and letters to the press can be used for benefit of improving one's own vocabulary and writing skills and style. I suggest the writings of three literati--Bernard Shaw, Bertrand Russell, and Ernest Hemingway--as palliatives for autotrophic plagiarism in scientific publishing.

  9. Social Movement Literature and U.S. Labour: A Reassessment

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Largely due to its conservative profile at the time, the U.S. labour movement was largely absent from modern social movement literature as it developed in response to the new social movements of the 1960s and 1970s. Recent labour mobilizations such as the Wisconsin uprising and the Chicago Teachers’ strike have been part of the current international cycle of protest that includes the Arab Spring, the antiausterity movements in Greece and Spain, and Occupy Wall Street. These struggles suggest that a new labour movement is emerging that shares many common features with new social movements. This article offers a general analysis of these and other contemporary labour struggles in light of contemporary modern social movement literature. It also critically reviews assumptions about the labour movement of the 1960s and 1970s and reexamines several social movement concepts.

    Perianal pseudolymphoma is a rare lymphoproliferative disorder that can mimic cutaneous lymphoma. The condition can present acutely with concerns of perianal sepsis. The purpose of this case review is to review the current literature on perianal pseudolymphoma and emphasise to the surgical community its presentation, suggested aetiology and management. In this case report, we detail the case of a 28-year-old female who presented with perianal pseudolymphoma. Malignant lymphoproliferative diseases required exclusion. Conservative management of this rare condition was successful. We highlight the differential diagnoses, investigations and treatment options for a rare condition. A review of the literature on the limited published data on perianal pseudolymphoma is briefly discussed. The aim of this case report is to highlight the existence of such a rare condition that can imitate an acute surgical presentation and its successful conservative management.

    Full Text Available This paper focuses on current issues relating to cultural encounters in contemporary Dutch literature. The starting point is transculturality - a concept suggesting a new way of looking at culture that is frequently applied as an alternative to concepts such as multi- and interculturality. This article deals with theoretical issues as well as with the question whether transculturality is appropriate when characterizing how cultural contacts are represented in literature. The results of this case study based on a literary analysis of Kader Abdolah’s short story “Een onbekende trekvogel” provide a strong argument for modifying the concept of transculturality and sharpening awareness for increasing interrelations of individuals, societies, institutions and nations.

    The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

  13. Factor structure of suggestibility revisited: new evidence for direct and indirect suggestibility

    Directory of Open Access Journals (Sweden)

    Romuald Polczyk

    2016-05-01

    Full Text Available Background Yielding to suggestions can be viewed as a relatively stable individual trait, called suggestibility. It has been long proposed that there are two kinds of suggestible influence, and two kinds of suggestibility corresponding to them: direct and indirect. Direct suggestion involves overt unhidden influence, while indirect suggestion concerns influence that is hidden, and the participant does not know that the suggestibility is being measured. So far however, empirical evidence for the existence of the two factors has been scarce. In the present study, more sophisticated and reliable tools for measuring suggestibility were applied than in the previous research, in the hope that better measurement would reveal the factor structure of suggestibility. Two tests of direct suggestibility were used: the Harvard Group Scale of Hypnotic Susceptibility, Form A, measuring hypnotic susceptibility, and the Barber Suggestibility Scale, measuring non-hypnotic direct imaginative suggestibility. Three tests served to measure indirect suggestibility: the Sensory Suggestibility Scale, measuring indirect suggestibility relating to perception; the Gudjonsson Suggestibility Scale, measuring the tendency to yield to suggestive questions and changing answers after negative feedback; and the Emotional Dialogs Tests, measuring the tendency to perceive nonexistent aggression. Participants and procedure In sum, 115 participants were tested, 69 women, 49 men, mean age 22.20 years, SD = 2.20. Participants were tested in two sessions, lasting for a total of four hours. Results Confirmatory factor analyses confirmed the existence of two uncorrelated factors of suggestibility: direct and indirect. Conclusions Suggestibility may indeed involve two factors, direct and indirect, and failure to discover them in previous research may be due to methodological problems.

    Appropriate identification and classification of online reviews to satisfy the needs of current and potential users pose a critical challenge for the business environment. This paper focuses on a specific kind of reviews: the suggestive type. Suggestions have a significant influence on both consumers' choices and designers' understanding and, hence, they are key for tasks such as brand positioning and social media marketing. The proposed approach consists of three main steps: (1) classify comparative and suggestive sentences; (2) categorize suggestive sentences into different types, either explicit or implicit locutions; (3) perform sentiment analysis on the classified reviews. A range of supervised machine learning approaches and feature sets are evaluated to tackle the problem of suggestive opinion mining. Experimental results for all three tasks are obtained on a dataset of mobile phone reviews and demonstrate that extending a bag-of-words representation with suggestive and comparative patterns is ideal for distinguishing suggestive sentences. In particular, it is observed that classifying suggestive sentences into implicit and explicit locutions works best when using a mixed sequential rule feature representation. Sentiment analysis achieves maximum performance when employing additional preprocessing in the form of negation handling and target masking, combined with sentiment lexicons.

    Biomarkers of effect are measurable biochemical, physiological or other alterations within an organism that can be recognized as causing an established or potential impairment of embryo-fetal development. They may be identified studying the mechanisms of action of teratogens. Hyperacetylation of histones, oxidative stress, cholesterol and retinoic acid unbalance are some of the identified mechanisms of action of some known teratogens. Nevertheless, their use is not currently applicable in human pregnancy because of the difficulty of the choice of biological material, the time when the material must be obtained, and the invasivity of methods. Furthermore, before using them in human pregnancy studies, biomarkers should be validated in experimental animals and in epidemiologic studies. On the contrary, some biomarkers could be useful in the screening of developmental toxicity of chemicals and drugs, comparing molecules of the same chemical class or with the similar pharmacologic activity, and using adequate in vitro tests, in order to reduce the use of experimental animals.

    This study examined the relative impact of hypnotic inductions and several other variables on hypnotic and nonhypnotic responsiveness to imaginative suggestions. The authors examined how imaginative suggestibility, response expectancies, motivation to respond to suggestions, and hypnotist-induced performance standards affected participants' responses to both hypnotic and nonhypnotic suggestions and their suggestion-related experiences. Suggestions were administered to 5 groups of participants using a test-retest design: (a) stringent performance standards; (b) lenient performance standards; (c) hypnosis test-retest; (d) no-hypnosis test-retest; and (e) no-hypnosis/hypnosis control. The authors found no support for the influence of a hypnotic induction or performance standards on responding to suggestions but found considerable support for the role of imaginative suggestibility and response expectancies in predicting responses to both hypnotic and nonhypnotic suggestions.

    Conclusion: There is much confusion in the categorization of clinical tuberculosis. The standardized WHO, CDC, and ATS definitions are not always adhered to in collating and analyzing tuberculosis data by authors studying extrapulmonary tuberculosis. The recommendation that pleural disease be considered extrapulmonary is not adhered to in a sizable percentage (32% of studies and the exclusion of disseminated or miliary disease in a subset of patients is also inconsistent. More restrictive guidelines are needed in the definitions used for tuberculosis so that studies and meta-analyses can be performed with greater validity.

    Pregnancy in women diagnosed with systemic sclerosis generally has a favorable outcome according to most recent studies. Women with systemic sclerosis who wish to become pregnant should achieve low disease activity for at least 6 months prior to conception. Regular follow-up of pregnant scleroderma patients by an interdisciplinary medical team including gynaecologists and rheumatologists is necessary to control disease activity and avoid possible complications. Severe organ involvement, early diffuse systemic sclerosis with rapid onset, and pulmonary hypertension ought to discourage patients from pregnancy, as these situations are at high risk of complications for both mother and fetus during pregnancy.

    The child's foot is clearly distinct from the adult foot in its functional anatomy and ability to cope with pressure. This requires special considerations in the development of a children's sport shoe. Medical and sport science databases were thoroughly searched for studies pertaining to the anatomy and biomechanics of children's feet during their development. With the data found, a list of requirements for the children's shoe was compiled. Small children should have a sports shoe, which is as flexible as their own foot. The small impact forces during their sports activities make extra cushioning superfluous. During school age the connective tissue gains stability. The growing amount of sports activities, much of which is performed on hard indoor surfaces, enhances the need for cushioning. At the same time there is a growing necessity for adequate mechanical stimuli to help the muscles and bones develop. The strength of the connective tissue and the flexibility of the joints reach adult levels by the age of 15. In small shoes, the displacement of proportions can lead to improper positioning of the flex zone and thereby causing harmful stress on the foot. Cushioning elements are often oversized. Considering the wide range of anatomy in the child's foot, it is advisable to produce children's shoes in different widths. The child's foot differs in anatomy and function from the adult foot. Children sport shoes should meet the child specific requirement.

    The mucocele of the appendix is an uncommon disorder which is often asymptomatic but sometimes causes acute appendicitis-like symptoms. Sometimes, patients with mucocele can present with confusing symptoms. Preoperative suspicion and diagnosis of appendiceal mucocele are important. Ultrasonography and computed tomography are useful tools for the diagnosis of appendiceal mucocele. It may be also recognised by colonoscopy as a smooth submucosal lesion of the cecum. Optimal management of the mucocele could be achieved through accurate preoperative diagnosis. Preoperative diagnosis is a major component for minimizing intra-operative and post-operative complications. We herein report five cases and discuss the diagnostic methods and surgical treatment.

    Science.gov (United States)

    Hollis, Amy; Arundel, Paul; High, Alec; Balmer, Richard

    2013-05-01

    BACKGROUND.  Hypophosphatasia (HP) is characterized by defective mineralization of bone and teeth because of deficient alkaline phosphatase activity. There are generally six recognized clinical forms, of which the most severe is often lethal prenatally or early in life. In milder forms, such as odontohypophosphatasia (OHP), premature exfoliation of primary teeth may be the only clinical manifestation. CASE REPORT.  A 20-month-old girl was referred to the Specialist Paediatric Salaried Dental Service within the Harrogate and District NHS Foundation Trust with mobility of tooth numbers 71 and 81. Clinical examination revealed grade III mobile 71 and 81, with minimal gingival inflammation and plaque deposits. There were no other dental findings and no significant medical history. Tooth numbers 71 and 81 exfoliated prematurely with no evidence of root resorption, shortly after presentation. Haematological and urinary investigations showed no abnormalities. Histological examination showed a complete absence of cementum. A diagnosis of OHP was made. After 10 months of dental follow-up, no further teeth have increased mobility. CONCLUSION.  Odontohypophosphatasia should be included as a differential diagnosis in children presenting with early loss of primary teeth. The dentist may be the first health care professional to whom the patient presents.

    Cryotherapy is often used in soft tissue sports injuries. The application of a cold pack reduces local muscular blood-flow by approximately 50% after 10 minutes. The duration of bleeding in a muscular injury is not known, but immediate application of external pressure is probably far superior in emergency treatment of an injury. Some studies have shown significant effect of cryotherapy in emergency treatment of ankle sprains, but external pressure is often applied simultaneously and the additive effect of cryotherapy is therefore uncertain. Cryotherapy reduces the metabolic rate in injured muscle and is often used several days after a soft tissue injury to reduce secondary hypoxic injury. Experimental studies, however, show no effect of cryotherapy on muscle regeneration, and no controlled clinical study has shown a significant effect in emergency treatment of soft tissue sports injuries.

    Good literary fiction has the potential to move us, extend our sense of life, transform our prospective views and help us in the face of adversity. A neurological disorder is likely to be the most challenging experience a human being may have to confront in a lifetime. As such, literary recreations of illnesses have a doubly powerful effect. Study the synergies between neurology and fictional literature with particular reference to narrative based medicine (NBM). Doctors establish boundaries between the normal and the abnormal. Taking a clinical history is an act of interpretation in which the doctor integrates the science of objective signs and measurable quantities with the art of subjective clinical judgment. The more discrepancy there is between the patient's experience with the illness and the doctor's interpretation of that disease, the less likely the doctor-patient interaction is to succeed. NBM contributes to a better discernment of the meanings, thus considering disease as a biographical event rather than just a natural fact. Drawing from their own experience with disease, writers of fiction provide universal insights through their narratives, whilst neuroscientists, like Cajal, have occasionally devoted their scientific knowledge to literary narratives. Furthermore, neurologists from Alzheimer to Oliver Sacks remind us of the essential value of NBM in the clinic. Integrating NBM (the narrative of patients) and the classic holistic approach to patients with our current paradigm of evidence based medicine represents a challenge as relevant to neurologists as keeping up with technological and scientific advances.

  5. Children's suggestibility research: Things to know before interviewing a child

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Children's testimony is often the only evidence of alleged abuse. Thus, the importance of conducting forensic interviews that are free from bias and misleading information is immense, as these could lead to false reports. In the current paper, we review unexpected findings in children's suggestibility that illustrate the difficulty in distinguishing between false and accurate reports. We explore situations in which a younger person's memory account may be more accurate than that of an adult, when a single suggestive interview may be as detrimental as multiple interviews, and when children can make inaccurate reports spontaneously. We conclude with recommendations for interviewers to decrease false reporting by both children and adults.

Partiendo del concepto de canon literario entendido este como una selección subjetiva de textos literarios, en este artículo proponemos un conjunto de obras de literatura infantil y juvenil escritas en español y portugués, publicadas entre 2005 y 2015, que puede formar parte de la Biblioteca Escolar por dos motivos fundamentales: por un lado, se trata de publicaciones actuales; por otro, con cada una de ellas se puede despertar el gusto por la lectura de unos textos escritos explícitamente para el público infantil y juvenil. Las obras seleccionadas las agrupamos, como sostiene la bibliografía actual sobre esta cuestión, en tres géneros: cuento y álbum ilustrado, poesía y teatro. Abstract The role of the librarian in the School Library is essential for this makes a good selection of titles that are adequate to arouse reader interest in young students. Based on the concept of literary canon understood as a subjective selection of literary texts, in this paper we propose a set of works of children's literature written in Spanish and Portuguese, published between 2005 and 2015, which may be part of the School Library by two fundamental reasons: firstly, it is current publications; on the other, each one can awaken the love of reading of texts written specifically for young audiences. The selected titles are grouped, as claimed by the current literature on this issue, in three genres: story and picture books, poetry and theater.

Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional assessment in a single imaging session. In this article, the authors review most technical aspects and suggest a protocol for performing chest MRI. The authors also describe the three major clinical indications for MRI of the lungs: staging of lung tumors; evaluation of pulmonary vascular diseases; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.

    2008-01-01

    Is gradual microevolutionary change within species simultaneously the source of macroevolutionary differentiation between species? Since its first publication, Darwin's original idea that phenotypic differences between species develop gradually over time, as the accumulation of small selection-induced changes in successive generations has been challenged by palaeontologists claiming that, instead, new species quickly acquire their phenotypes to remain virtually unchanged until going extinct again. This controversy, widely known as the ‘punctuated equilibrium’ debate, remained unresolved, largely owing to the difficulty of distinguishing biological species from fossil remains. We analysed body masses of 2143 existing mammal species on a phylogeny comprising 4510 (i.e. nearly all) extant species to estimate rates of gradual (anagenetic) and speciational (cladogenetic) evolution. Our Bayesian estimates from mammals as well as separate sub-clades such as primates and carnivores suggest that gradual evolution is responsible for only a small part of body size variation between mammal species.

    2014-06-01

    Full Text Available OBJECTIVE: this study aimed to evaluate the usefulness of current radiographic measurements, which were originally conceived to evaluate adenoid hypertrophy, as potential referral parameters. METHODS: children aged from 4 to 14 years, of both genders, who presented nasal obstruction complaints, were subjected to cavum radiography. Radiographic examinations (n = 120 were evaluated according to categorical and quantitative parameters, and data were compared to gold-standard videonasopharyngoscopic examination, regarding accuracy (sensitivity, negative predictive value, specificity, and positive predictive value. RESULTS: radiographic grading systems presented low sensitivity for the identification of patients with two-thirds choanal space obstruction. However, some of these parameters presented relatively high specificity rates when three-quarters adenoid obstruction was the threshold of interest. Amongst the quantitative variables, a mathematical model was found to be more suitable for identifying patients with more than two-thirds obstruction. CONCLUSION: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy.

Here, we review the current literature in terms of suggested mechanism, efficacy, method of treatment, predictors of success, adverse events, repeatability, and cost of SLT. The exact mechanism by which SLT lowers intraocular pressure (IOP remains unknown although circumstantial evidence has come in many forms in relation to structural alteration; oxidative stress and inflammatory responses; tight junction integrity; proliferative responses; and microbubble formation. SLT is as effective as argon laser trabeculoplasty and medications in reducing IOP in glaucoma and ocular hypertension. The treatment is not uniformly effective in all eyes, and its IOP-lowering effect decreases over time. High pretreatment IOP is the strongest predictor of success; however, significant pressure reduction has also been shown in normal-tension glaucoma and in patients already taking multiple antiglaucoma drops. Mild, transient adverse effects are common. Transient IOP spikes usually resolve quickly with or without antiglaucoma treatment but may be problematic in pigmented angles. The limited available evidence suggests SLT is repeatable and cost-effective for the treatment of glaucoma and ocular hypertension. Keywords: glaucoma, SLT, ocular hypertension, intraocular pressure

  18. Individualist and collectivist values: hypotheses suggested by Alexis de Tocqueville.

    Watson, P J; Morris, Ronald J

    2002-05-01

    The work of Alexis de Tocqueville, the 19th-century social theorist who coined the term individualism, supplied a conceptual foundation for hypothesizing that individualism and collectivism, as value systems, should be directly correlated. In previous research (D. K.-S. Chan, 1994), individualist and collectivist values were negatively correlated in a sample of men, and in a combined sample of men and women (P. J. Watson, J. Sherbak, & R. J. Morris, 1998) these values were positively correlated. In the present study, a positive relationship was in fact observed in both men and women. Linkages with other measures of self and social functioning uncovered a few small associations of individualist values with maladjustment. Collectivist values predicted adjustment. These data confirm that individualist and collectivist values are compatible, just as Tocqueville had suggested, and that gender differences do not explain the conflicting results previously reported in this literature.

In particular, a comparative quantitative analysis over a large corpus of the recent literature suggests that the potential of auditory feedback in rehabilitation systems is currently and largely underexploited. Finally, several scenarios are proposed in which the use of auditory feedback may contribute to overcome some of the main limitations of current rehabilitation systems, in terms of user engagement, development of acute-phase and home rehabilitation devices, learning of more complex motor tasks, and improving activities of daily living.

    Full Text Available In five experiments, Leishmania (Leishmania major (MRHO/SU/59/P-strain grew poorly when seeded in FYTS medium supplemented with 15% fetal calf serum, but presented several peculiar pairs of promastigotes diametrically opposed and attached at their posterior ends (5.8-13.5%. As seen in Giemsa-stained smears, a ring-like line and/or an enlargement, generally occurred at the parasite junction. A close proximity of nuclei, which sometimes were difficult to distinguish from each other, was also observed at this junction. Several of these pairs appeared to be composed of fused cells in which the nuclei could be apparently fused, as shown by fluorescence microscopy to detect ß-tubulin and DNA, and by scanning electron microscopy. Under other culture conditions these pairs were absent or occurred at very low rates (0.2-2.2%. Such pairs differ markedly from longitudinally dividing cells and resemble those described in two other Leishmania species, as well as in Herpetomonas megaseliae and Phytomonas davidi, suggesting steps of a putative sexual process

    Full Text Available This study aims to identify the problems encountered in production lines for office furniture manufacturers and gives suggestions to the problems. For this response, a questionnaire was designed and conducted with directors or owners of 50 office furniture manufacturers of small, medium and large scale size enterprises which were randomly selected from different cities. The questionnaire aims to focus on identifying the fundamental obstacles for production, marketing, sales and law. The data from questionnaire was calculated with frequency numbers and percentages for statistical values. In respect to the scope of dependent variables for the study, relationships between the independent variables such as the size of the company scale and Chi Square Single Analysis of Variance (ANOVA were determined. According to the results, 52% of customers constitute owners. The biggest obstacle is the lack of qualified personnel in office furniture production while 46% of customers complain about pour designs. As a result, the study concludes with specific obstacles for logistics (30%, distributions (18%, unpaid bills after delivery (28%, and unconscious of the consumer (24% in the office furniture sector.

    Human organ, as the basic structural and functional unit in human body, is made of a large community of different cell types that organically bound together. Each organ usually exerts highly specified physiological function; while several related organs work smartly together to perform complicated body functions. In this study, we present a computational effort to understand the roles of genes in building functional connection between organs. More specifically, we mined multiple transcriptome datasets sampled from 36 human organs and tissues, and quantitatively identified 3,149 genes whose expressions showed consensus modularly patterns: specific to one organ/tissue, selectively expressed in several functionally related tissues and ubiquitously expressed. These pattern genes imply intrinsic connections between organs. According to the expression abundance of the 766 selective genes, we consistently cluster the 36 human organs/tissues into seven functional groups: adipose & gland, brain, muscle, immune, metabolism, mucoid and nerve conduction. The organs and tissues in each group either work together to form organ systems or coordinate to perform particular body functions. The particular roles of specific genes and selective genes suggest that they could not only be used to mechanistically explore organ functions, but also be designed for selective biomarkers and therapeutic targets.

  3. Tag Correspondence Model for User Tag Suggestion

    2015-01-01

    Some microblog services encourage users to annotate themselves with multiple tags, indicating their attributes and interests. User tags play an important role for personalized recommendation and information retrieval. In order to better understand the semantics of user tags, we propose Tag Correspondence Model (TCM) to identify complex correspondences of tags from the rich context of microblog users. The correspondence of a tag is referred to as a unique element in the context which is semantically correlated with this tag. In TCM, we divide the context of a microblog user into various sources (such as short messages, user profile, and neighbors). With a collection of users with annotated tags, TCM can automatically learn the correspondences of user tags from multiple sources. With the learned correspondences, we are able to interpret implicit semantics of tags. Moreover, for the users who have not annotated any tags, TCM can suggest tags according to users’ context information. Extensive experiments on a real-world dataset demonstrate that our method can effciently identify correspondences of tags, which may eventually represent semantic meanings of tags.

    Worldwide, children can be found who reported that they have memories of a previous life. More than 2,500 cases have been studied and their specifications have been published and preserved in the archives of the Division of Perceptual Studies at the University of Virginia (United States). Many of those children come from countries where the majority of the inhabitants believe in reincarnation, but others come from countries with different cultures and religions that reject it. In many cases, the revelations of the children have been verified and have corresponded to a particular individual, already dead. A good number of these children have marks and birth defects corresponding to wounds on the body of his previous personality. Many have behaviors related to their claims to their former life: phobias, philias, and attachments. Others seem to recognize people and places of his supposed previous life, and some of their assertions have been made under controlled conditions. The hypothesis of reincarnation is controversial. We can never say that it does not occur, or will obtain conclusive evidence that it happens. The cases that have been described so far, isolated or combined, do not provide irrefutable proof of reincarnation, but they supply evidence that suggest its reality.

  5. Suggested use of vaccines in diabetes

    Full Text Available Diabetes has emerged as a disease of major public health importance in India affecting the rich and the poor alike. Conventionally, comprehensive diabetes management is aimed at preventing micro and macro vascular complications. However, morbidity and mortality due to infections are also significant. In developing countries like India, the concept of adult immunization is far from reality. Recently the H1N1 pandemic has triggered the necessity for considering immunization in all age groups for the prevention of vaccine-preventable fatal infectious diseases. Considering the economics of immunization in a developing country, providing free vaccines to all adults may not be a practical solution, although the free universal immunization program for children is in existence for several decades. There is no consensus on the use of vaccines in diabetes subjects in India. However, there are some clinics offering routine pneumococcal, influenza and other vaccinations. Patients with diabetes have a deranged immune system making them more prone for infections. Hospitalization and death due to pneumococcal disease and influenza are higher in diabetes patients. They, like other healthy individuals, have a normal humoral response to vaccination with clinically significant benefits. The American Diabetes Association, Advisory Committee on Immunization Practices, Centers for Disease Control and Prevention, World Health Organization, United Kingdom Guidelines and a number of other scientific organizations have well defined guidelines for vaccination in diabetes. In this article we make some suggestions for clinicians in India, regarding use of vaccines in subjects with diabetes.

    Full Text Available Including in a novel information about relief, climate, vegetation, fauna and various aspects of socio-economic life can make literature a real source of geographical information. Using realistic literary works in Geography lessons has multiple benefits, which are not limited only to geographical knowledge. In this paper there are some fragments from literature, suggestions of activities about how to integrate the fragments during Geography lessons and the results of these activities. The activities are from fifth to twelfth grade, passing through a first example of water pollution resulting from a Hercules labour, through the lyricism of the aurora borealis description, through the dramatic life of a refugee from Darfur, through the Dobrudgea winter landscape, through the grey urban landscape of Bucharest in the 90s and so on. Students were put into learning situations that stimulated their creativity, developed communication competencies and enriched their general knowledge.

    J. Hillis Miller

    2012-01-01

    Full Text Available The essay in question is the translation of the fourth chapter of J. Hillis Miller’s book, On literature (2002, in which he circles around questions elemental yet convoluted for literary criticism. Miller reminds us about (as ancient as archetypal dilemmas concerning the role of literature in society (e.g. Plato’s putdown of poetry and Aristotle’s defense of it and discloses contemporary judgments covertly rooted in them. The fundamental issue is why Western culture has granted literature such great authority. His argument reposes on an assumption that literary works give us access to virtual realities that are not otherwise knowable.

  12. Applied Literature for Healing,

    Directory of Open Access Journals (Sweden)

    Susanna Marie Anderson

    2014-11-01

    Full Text Available In this qualitative research study interviews conducted with elite participants serve to reveal the underlying elements that unite the richly diverse emerging field of Applied Literature. The basic interpretative qualitative method included a thematic analysis of data from the interviews yielding numerous common elements that were then distilled into key themes that elucidated the beneficial effects of engaging consciously with literature. These themes included developing a stronger sense of self in balance with an increasing connection with community; providing a safe container to engage challenging and potentially overwhelming issues from a stance of empowered action; and fostering a healing space for creativity. The findings provide grounds for uniting the work being done in a range of helping professions into a cohesive field of Applied Literature, which offers effective tools for healing, transformation and empowerment.

    Full Text Available Abstract: Literature and Institution. The aim of this paper is to discuss concepts and beliefs about what is understood by “literature”. Based, at first, on post-modern views of some literary critics and philosophers such as: Terry Eagleton and Jacques Derrida, this work does not intend to define literature precisely, but, mainly, put in doubt or raise questions which are highly relevant to the reflection of the professionals who work with Brazilian and Foreign Literature, as well as for the theoreticians and literary critics, who contribute to the continuity of prescriptive and pre-conceived thoughts and, at the same time, restrain the thinking of a different and more critical view of institutionalized, established values. Keywords: literature; literary text; values; institution.

    Full Text Available Abstract: Two majors linguistics and literature in the schools of letters both in the state and private universities throughout Indonesia are commonly separated sharply. Courses of literature in the Department of Linguistics are offered minimally, such that the students of linguistics are not given a conducive atmosphere to express their literary appreciation. Likewise, courses of linguistics in the Department of Literature are very restricted, so that the students of literature are unable to analyze literary works from the points of linguistic view. This paper tries to bridge linguistics and literature. The attempt to bridge linguistics and literature is based on three postulates: (I literature consists of linguistic objects designed with an artistic end, (2 linguistic objects are formal objects, and (3 a formal account of linguistic object designed with an artistic end approximates a formal account of that artistic design. Two major directions in the approaches and emphases will be presented in the paper exogenous and endogenous. Exogenous approach tries to search for adequate description of (1 poetic language as contrasted with ordinary language, (2 language of a particular author contrasted with that of other authors, and (3 a particular literary work contrasted with other works of the same author. This part touches upon three areas of exogenous approach isolation, description, and characterization. Endogenous, on the hand, is based upon an assumption that a writer exhibits, probably without realizing it, certain systematic preferences for particular aspects of linguistic patterns. Planning a bridge between linguistics and literature is by no means without problems. Therefore, this paper also presents some possible solutions.

    Science.gov (United States)

    Courtney, Michael W; Snider, Taylor N; Cottrell, David A

    2010-01-01

    Diabetes mellitus was once considered a contraindication to the use of dental implant therapy as it has been associated with comorbidities, including increased susceptibility to infection, impaired wound healing, and periodontitis. Since dental implants and techniques for controlling diabetes have evolved, dental implant therapy has become increasingly common among patients with diabetes. The rising success of dental implants, along with the realized benefits of implant therapy has shifted current trends to accommodate patients with controlled diabetes as good candidates for treatment. The literature currently suggests that successful treatment results can be attained when placing implants on carefully selected patients with glycosylated hemoglobin levels (HbA1C) less than 8 percent and with possible prophylactic antibiotic administration. This review aims to compile and critically evaluate the current literature for placement of dental implants in patients with diabetes.

  20. Organizational Commitment, job satisfaction and intention to stay: Literature review

    Directory of Open Access Journals (Sweden)

    Joan Llobet

    2013-12-01

    Full Text Available Purpose: The aim of this paper is to analyse the existing theoretical frameworks of organisational behaviour and job satisfaction while taking into account, in connection with working conditions, the social and economic changes that are taking place in most of the western countries. The analysis and discussion suggest the need for new lines of research to determine whether the current practices carried out in human resources departments are well directed. Design/methodology/approach: First, we show a short review of the classical literature and the predominant paradigms through an exhaustive review of the scientific literature that has led to their subsequent evolution. Afterwards, we analyse the evidence sustaining their evolution in the light of the current changes, and we explain the future research needs from a theoretical point of view. Research limitation/implications: Owing to the nature of the article, it is a theoretical essay to launch a new scientific debate in connection with the models displayed and fully justified. Practical implications depend on the development of future research, as justified at all times. Originality/value: Currently, few investigations and theoretical contributions have taken into account the increase in contingent work, and more specifically moonlighting, either from an empirical perspective or as a theoretical critique of the existing organisational behaviour models. The main value of this essay is its invitation to take control of the debate while analysing its possible practical implications.

    2010-01-01

    Supernumerary tooth is one of the developmental problems in children. Mesiodens is a supernumerary tooth present in the midline between the two central incisors. It usually results in oral problems such as malocclusion, food impaction, poor aesthetics, and cyst formation. The prevalence of mesiodens varies between 0.09% and 2.05% in different studies. This paper reviews current literature on etiology, prevalence, diagnosis, and management of this problem. Accordingly, early diagnosis and treatment is suggested to prevent orthodontic and pathologic complications.

    Full Text Available Background: the aim of the article is to conduct an overview of the impact of OA on the medical articles based on 3-part categorization.Methods: Data were identified by a search strategy with eight combinations of keywords (open access, citation impact, citation advantage, citation count, article download, article usage, social media attention, altmetrics and searched in three different databases.Results: the analysis was conducted on 107 studies dealing with citations, downloads and social impact. Sixty-seven of them simply employed the counting citations to OA and non-OA articles; nineteen articles compared the downloads and citations counts; and twenty-one articles investigated the social impact of OA articles. Twenty-five articles investigated the citations, download counts, and social impact of medical articles.Conclusions: The studies investigating the citation impact mostly showed citation advantages. Those that employed citation and download counts of medical articles using randomized controlled trials showed that OA articles were downloaded significantly more frequently, but found no evidence of a citation advantage for open access articles. The citation advantage from open access might be caused by other factors. Results of the studies comparing the social media attention and citations/downloads of the medical articles are often diametrically opposed.

    Global imbalance is the main feature and risk in the current world economy, and becomes the hot issue in the academic field. The paper reviews the related literature on the global imbalance which covers its causes, sustainabili- ty and adjustment. The paper explores the major causes of current global imbal- ance from the perspectives of elasticity of exchange rate, save-investment, global portfolio and statistics failure. Then the two competing views on sustainability are introduced before brief comments are made. Furthermore, we review the litera- ture on the adjustment means and cost of current global imbalance, and what roles China takes in the adjustment of current global imbalance. On the base of these, we point out the lack of current research and future research direction.%全球经济失衡是当今世界经济运行的主要特征和面临的重要风险,因而成为学术界、政策制定者和国际机构竞相研究的热点问题。本文通过回顾相关文献,重点研究了当前全球经济失衡的主要成因、可持续性及其调整。论文从汇率弹性视角、储蓄投资视角、全球资产组合视角、国际分工视角和统计失效视角探讨了当前全球经济失衡的主要成因;介绍了有关可持续性的两种不同观点,并作了简要评述;综述了全球经济失衡的调整路径及中国在当前全球经济失衡调整中的地位与作用等;在此基础上,指出了目前研究的不足,并对未来的研究方向和重点作了展望。

  5. Perinatal pathology: practice suggestions for limited-resource settings.

    Science.gov (United States)

    Roberts, Drucilla J

    2013-06-01

    The practice of perinatal pathology in much of the world suffers, as do all subspecialties of anatomic pathology, from inadequate resources (equipment, consumables, and both professional and technical personnel), from lack of education (not only of the pathologist but also of the clinicians responsible for sending the specimens, and the technicians processing the specimens), and from lack of appropriate government sector support. Perinatal pathology has significant public health-related utility and should be championing its service by providing maternal and fetal/infant mortality and morbidity data to governmental health ministries. It is with this pathologic data that informed decisions can be made on health-related courses of action and allocation of resources. These perinatal pathology data are needed to develop appropriate public health initiatives, specifically toward achieving the Millennium Developmental Goals as the best way to effectively decrease infant and maternal deaths and to determine causes of perinatal mortality and morbidity. The following overview will focus on the utility of perinatal pathology specifically as related to its public health function and will suggest methods to improve its service in resource-poor settings. This article is offered not as a critique of the current practice that most pathologists find themselves working in globally, but to provide suggestions for improving perinatal pathology services, which could be implemented with the limited available resources and manpower most pathology departments currently have. In addition, we offer suggestions for graded improvements ("ramping up") over time.

Der Band enthält die Beiträge zu einem Symposion, das am 14.-15. Januar 2005 an der Universität Nottingham stattgefunden hat. Im Mittelpunkt stand die Frage, welche Strategien im Umgang mit Nationalsozialismus, Holocaust, zweitem Weltkrieg, Kaltem Krieg oder Vietnamkrieg und auch dem deutschen Kolonialismus bei Bachmann und anderen deutschsprachigen Autoren zu finden sind. Anlass zur Tagung war die in Wien und Salzburg konzipierte Ausstellung Schreiben gegen den Krieg: Ingeborg Bachmann, 1926-1973. In insgesamt dreizehn Beiträgen wird im vorliegenden Band die literarische Auseinandersetzung mit dem Thema Gewalt und Krieg beleuchtet.Volume 19 of the series published by the Erich-Maria-Remarque Archive is entitled “Writing against War and Violence” (“Schreiben gegen Krieg und Gewalt” and approaches Ingeborg Bachmann and German language literature from 1945 to 1980. The volume contains contributions based on a symposium that took place at the University of Nottingham on January 14-15, 2005. Central to the symposium was the question as to which strategies Bachmann and other German language authors utilized in their approach to National Socialism, the Holocaust, the Second World War, the Cold War, or the Vietnam War, as well as German colonialism. The impetus for the conference was the exhibition Writing Against the War: Ingeborg Bachmann, 1926-1973 conceived in Vienna and Salzburg. In the volume at hand, thirteen contributions in total illuminate literary confrontations with the themes of war and violence.

  8. On current trace problem

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The pricing of electricity trasmission requires determining how much use each generator is making of a transmission line and what is each generator's contribution to the system losses. Such problems cannot be solved by only using Kirchoff's laws. This paper proposes two current decomposition axioms based on which the theories and models are established for the current trace problem. To create an efficient algorithm the graph theory is employed. It is proved that there is no directed circuit in a directed current distribution graph. According to this theorem a very simple and efficient algorithm based on recursive elimination process is suggested. A simple example is used to explain the algorithm.

  10. Current ornithology

    CERN Document Server

    1983-01-01

    The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi­ ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic­ tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con­ cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily­ identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old.

    2015-01-01

    Hypnotic suggestibility (HS) is the ability to respond automatically to suggestions and to experience alterations in perception and behavior. Hypnotically suggestible participants are also better able to focus and sustain their attention on an experimental stimulus. The present study explores the relation between HS and susceptibility to the rubber hand illusion (RHI). Based on previous research with visual illusions, it was predicted that higher HS would lead to a stronger RHI. Two behavioral output measures of the RHI, an implicit (proprioceptive drift) and an explicit (RHI questionnaire) measure, were correlated against HS scores. Hypnotic suggestibility correlated positively with the implicit RHI measure contributing to 30% of the variation. However, there was no relation between HS and the explicit RHI questionnaire measure, or with compliance control items. High hypnotic suggestibility may facilitate, via attentional mechanisms, the multisensory integration of visuoproprioceptive inputs that leads to greater perceptual mislocalization of a participant's hand. These results may provide insight into the multisensory brain mechanisms involved in our sense of embodiment.
