    In this review article, we examine some of the conceptual contributions of sociology of health and illness over the past fifty years. Specifically, we focus on research dealing with medicalization, the management of stigma, research on adherence and compliance, and patient-doctor interaction. We show how these themes that originated within sociology, diffused in other disciplines. Sociology in Social Science and Medicine started as an applied research tradition but morphed into a robust, stand-alone social science tradition. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Anniversary Paper: Nuclear medicine: Fifty years and still counting

    Williams, Lawrence E.

    2008-01-01

    The history, present status, and possible future of nuclear medicine are presented. Beginning with development of the rectilinear scanner and gamma camera, evolution to the present forms of hybrid technology such as single photon emission computed tomography/computed tomography (CT) and positron emission tomography/CT is described. Both imaging and therapy are considered and the recent improvements in dose estimation using hybrid technologies are discussed. Future developments listed include novel radiopharmaceuticals created using short chains of nucleic acids and varieties of nanostructures. Patient-specific radiotherapy is an eventual outcome of this work. Possible application to proving the targeting of potential chemotherapeutics is also indicated

    Preparation for the fiftieth anniversary of human spaceflight in the spring of 2011 provides the space faring nations with an opportunity to reflect on past achievements as well as consider the next fifty years of human spaceflight. The International Space Station is a unique platform for long duration life science research that will play a critical role in preparing for future human space exploration beyond low earth orbit. Some feel the future path back to the Moon and on to Mars may be delayed with the current commitment of the United States to support the development of human-rated commercial spacecraft. Others see this as a unique opportunity to leverage the capability of the private sector in expanding access to space exploration. This article provides an overview of the past achievements in human spaceflight and discusses future missions over the next fifty years and the role space medicine will play in extending the time-distance constant of human space exploration.

  8. Fifty years of Technical Cooperation

    International Nuclear Information System (INIS)

    2007-01-01

    The International Atomic Energy Agency (IAEA) was established in Vienna in 1957. The Statute of the IAEA, approved by 81 nations, founded the organization on three pillars: nuclear verification; safety and security; and the transfer of technology. Today, these three pillars still remain at the heart of the organization's work. However, the way in which the IAEA carries out this work, particularly with regard to technology transfer, has changed greatly over the years. When the IAEA opened for business, nuclear science and technology were in their infancy. Many Member States had no nuclear capacity at all. The IAEA's 'technical assistance' programme, as it was then known, was modest. Early projects were small in scale and short lived, focusing mainly on building human capacities and creating institutions and facilities that would support the introduction of nuclear technology in a safe and effective manner. Today, the picture is more complex. Instead of merely offering assistance, the IAEA focuses on cooperation for sustainable socioeconomic development, building on the skills and infrastructure that Member States have acquired over the past five decades. Member States are full partners in the process, guiding the IAEA's technical cooperation activities, setting national and regional priorities, and offering training opportunities and technical support to the IAEA and to other Member States. Technical cooperation between developing countries is facilitated and supported through regional cooperative agreements. Regional centres of expertise play an important role in sharing the benefits of nuclear science and technology among Member States

  9. Vannevar Bush: Fifty Years Later

    1995-12-01

    It is ironic that the 50th anniversary year of Vannevar Bush's Report to President Truman entitled "Science the Endless Frontier", which put into motion the eminently successful current system of education of scientists in this country occurs at a time when serious questions are being asked about the usefulness of that very system. Bush viewed his proposal to establish a national research foundation (later to be called the National Science Foundation) as a "social compact." Judgment of scientific merit would be delegated to expert peers in return for scientific progress, which would ultimately benefit the nation in terms of scientific needs--military security, economic productivity, and enhanced quality of life. Bush wanted the funding of basic research intertwined with training, and preferred to use universities for this purpose rather than industrial or national labs. Bush viewed college and university scientists as teachers and investigators. He believed university-based research would uniquely encourage and engage the next generation of scientists as no other institutional arrangement could. Bush did not trust industry's commitment to basic research, an instinct that proved prophetic. The academic reserve of scientists (PhD's in training and postdoctoral students) that existed before World War II, and upon which the United States could draw for its needs, which were primarily associated with defense efforts, was probably one of the defining factors in Bush's suggested strategy. Currently, that reserve of talent has gotten so large that it is the obvious throttle in the pipeline slowing the continued development of the university research enterprise. Since 1977, the rate at which we have trained new scientists exceeds an average of 4% annually. Since 1987, the "science work force"--PhD's--has grown at three times the rate of the general labor supply. Temporary positions for postdoctoral scientists have grown even faster (over 5% per year since 1989). To compound

    2017-04-01

    We are here, of course, because 1967 saw the publication of John Ramsay's famous book. Two years later a memorable field trip from Imperial College to the Outer Hebrides saw John on a bleak headland on the coast of North Uist where a relatively undeformed metadolerite within Lewisian (Precambrian) gneisses contained ductile shear zones with metamorphic fabrics in amphibolite facies. One particular outcrop was very special - a shear zone cutting otherwise completely isotropic, undeformed metadolerite, with an incremental foliation starting to develop at 45° to the deformation zone, and increasing in intensity as it approached the shear direction. Here was proof of the process of simple shear under ductile metamorphic conditions - the principles of simple shear outlined in John Ramsay's 1967 book clearly visible in nature, and verified by Ramsay's mathematical proofs in the eventual paper (Ramsay and Graham, 1970). Later work on the Lewisian on the mainland of Scotland, in South Harris, in Africa, and elsewhere applied Ramsay's simple shear principles more liberally, more imprecisely and on larger scale than at Caisteal Odair, but in retrospect it documented what seems now to be the generality of mid and lower crustal deformation. Deep seismic reflection data show us that on passive margins hyper-stretched continental crust (whether or not cloaked by Seaward Dipping Reflectors) seems to have collapsed onto the mantle. Crustal faults mostly sole out at or above the mantle - so the Moho is a detachment- an 'outer marginal detachment', if you like, and, of course, it must be a ductile shear. On non-volcanic margins this shear zone forms the first formed ocean floor before true sea floor spreading gets going to create real oceanic crust. Gianreto Manatschal, Marcel Lemoine and others realised that the serpentinites described in parts of the Alps are exposed remnants of this ductile shear zone. Associated ophicalcite breccias tell of sea floor exposure, while high

    2017-09-01

    Chemical Physics Letters was born in 1967. In the first Number, published in February that year, the Founding Editors, Jan Hoytink and Laurens Jansen, stipulated that the journal would be truly international and that all submitted papers will be refereed. The aim was to provide a convenient means for the rapid dissemination of research results in the field of chemical physics. There would be an emphasis on theoretical interpretation. This article reviews the progress of the journal over its first fifty years.

    Rumors of its demise notwithstanding, nuclear magnetic resonance (NMR) continues to flourish fifty years after our birth. The lecture will be a reminiscence about moments of excitation, coherence and relaxation in the history of NMR which produced, among other developments, spin echoes and time reversal, Fourier transform and multidimensional spectroscopy, magnetic resonance imaging, and high resolution solid state NMR. Applications of modern NMR spectroscopy cut across the boundaries of physics, chemistry, materials, biology and medicine.

    factors such as those mentioned above must be considered in interpreting the effect of the atomic bombing, instead of ascribing all the effects solely to ionizing radiation. Fifty years ago, in 1945, the first three atomic bombs in human history were produced by the United States; one of these bombs was exploded experimentally at the testing ground in the desert 80 km from Alamogordo, New Mexico, on 16 July. The remaining two were used against Japan; the one called L ittle Boy , using Uranium 235 was dropped on Hiroshima on 6 August, the other F at Man , using Plutonium 239 on Nagasaki on 9 August, 1945

    The last 50 years in allergy could almost be considered the first 50 years. Over this time period, we have witnessed the emergence of allergy as a subspecialty, have seen and continue to observe a tremendous change in prevalence of allergic disease and have gained insight into the mechanisms that underlie allergic predisposition and disease manifestation. We have improved the care of children with many forms of allergic disease and now sit poised to be able to alter the natural history of allergic disease with the use of specific immunotherapy. There is much left to do in the next 50 years including understanding what underlies both the predisposition to atopic disease and its natural resolution and identifying the environmental cofactors involved in the 'allergic epidemic' and therefore targets for effective primary prevention. © 2015 The Authors.

    The nuclear community around the world will be marking the 50th anniversary of President Eisenhower's Atoms for Peace Speech on 8 December 2003. The Lawrence Livermore National Laboratory is organising a series of seminars in the US, Japan and France which will culminate in consensus statement Atoms for Peace after 50 Years; New Challenges and Opportunities. A separate initiative has seen the foundation of the World Nuclear University with the mission to strengthen international institutions to guide the ongoing development of the peaceful nuclear technology. The challenge for the nuclear community over the next 50 years is to redefine and recommit to the old vision in a new world challenged by new dimensions in national security, by environmental degradation and by the impacts of population pressures coupled with predicted climate change

  20. Fifty Years of Innovation in Plastic Surgery

    2016-03-01

    Full Text Available BackgroundInnovation has molded the current landscape of plastic surgery. However, documentation of this process only exists scattered throughout the literature as individual articles. The few attempts made to profile innovation in plastic surgery have been narrative, and therefore qualitative and inherently biased. Through the implementation of a novel innovation metric, this work aims to identify and characterise the most prevalent innovations in plastic surgery over the last 50 years.MethodsPatents and publications related to plastic surgery (1960 to 2010 were retrieved from patent and MEDLINE databases, respectively. The most active patent codes were identified and grouped into technology areas, which were subsequently plotted graphically against publication data. Expert-derived technologies outside of the top performing patents areas were additionally explored.ResultsBetween 1960 and 2010, 4,651 patents and 43,118 publications related to plastic surgery were identified. The most active patent codes were grouped under reconstructive prostheses, implants, instruments, non-invasive techniques, and tissue engineering. Of these areas and other expert-derived technologies, those currently undergoing growth include surgical instruments, implants, non-invasive practices, transplantation and breast surgery. Innovations related to microvascular surgery, liposuction, tissue engineering, lasers and prostheses have all plateaued.ConclusionsThe application of a novel metric for evaluating innovation quantitatively outlines the natural history of technologies fundamental to the evolution of plastic surgery. Analysis of current innovation trends provides some insight into which technology domains are the most active.

  1. Fifty years of German nuclear legislation

    International Nuclear Information System (INIS)

    Heller, W.

    2006-01-01

    The political situation and the state of legislation after World War II make it difficult to pinpoint a precise date of origin of German nuclear legislation. The restrictions imposed by the Allied High Commission (AHC) without any exception put a ban on the production of uranium and thorium metal as well as the construction of nuclear reactors. These restrictions were lifted expressly when the German Atomic Energy Act (AtG) entered into force on January 1, 1960, i.e. much later than the formal step of gaining sovereignty, which was marked by the protocol of May 5, 1955 terminating the Occupation Statute. In October 1955, the German federal government established the then Federal Ministry for Atomic Matters also in an attempt to reconnect to developments in nuclear fission in other parts of the Western world. To supersede the AHC law, the German federal government in December 1956 publicized a draft Atomic Energy Act. It is safe, therefore, to consider that year the starting point of German atomic legislation. This step was followed by deliberations preparatory to the adoption of the Atomic Energy Act. In 1957, however, adoption failed because no two-thirds majority was reached to amend the Basic Law, i.e. the Constitution. As a consequence, some federal states saw the need to adopt state legislation to regulate this area. On December 3, 1959, a new draft Atomic Energy Act was adopted by the German federal parliament after the second and third readings - coupled with an amendment to the Basic Law on that same day - with the votes of the opposition and with one abstention.

    President Eisenhower's hopes for nuclear technology still resonate, but the challenges to fulfilling them are much different today. On December 8, 1953, President Eisenhower, returning from his meeting with the leaders of Britain and France at the Bermuda Summit, flew directly to New York to address the United Nations General Assembly. His presentation, known afterwards as the ''Atoms for Peace'' speech, was bold, broad, and visionary. Eisenhower highlighted dangers associated with the further spread of nuclear weapons and the end of the thermonuclear monopoly, but the president also pointed to opportunities. Earlier that year, Stalin had died and the Korean War armistice was signed. Talks on reunification of Austria were about to begin. The speech sought East-West engagement and outlined a framework for reducing nuclear threats to security while enhancing the civilian benefits of nuclear technology. One specific proposal offered to place surplus military fissile material under the control of an ''international atomic energy agency'' to be used for peaceful purposes, especially economic development. Eisenhower clearly recognized the complex interrelationships between different nuclear technologies and the risks and the benefits that accrue from each. The widespread use of civilian nuclear technology and absence of any use of a nuclear weapon during the next half-century reflects success in his approach. Today, the world faces choices about nuclear technology that have their parallels in the Eisenhower calculus and its legacy. Although his specific fissile material proposal was never implemented, his broader themes gave impetus to agreements such as the nuclear Non-Proliferation Treaty (NPT) and institutions such as the International Atomic Energy Agency (IAEA). The resulting governance process has promoted some and restricted other nuclear technology. Perhaps even more influential was Eisenhower's overarching recommendation that we try to reduce the risks and seek

    electromagnetic modes, arrays of coupled cavities [5-7], and optomechanical systems [8] have further enriched the physics of the Jaynes-Cummings model. From the early interests in masers and the consistent quantum description of radiation and atom-photon interaction, the Jaynes-Cummings model has evolved into a cornerstone of quantum state engineering [9]. The authors of this editorial had not been born when Jaynes and Cummings wrote their remarkable paper. It is, therefore, a special honour for us to be able to draw the reader's attention to the accompanying reminiscence contributed by Frederick Cummings where he gives us a glimpse of the early history of the Jaynes-Cummings model from his perspective [11]. By now, the original 1963 paper by Jaynes and Cummings has gathered numerous citations and, at the time of writing, the number of articles involving Jaynes-Cummings physics is approaching 15 000.1 This special issue does not attempt to review this impressive wealth of research. The interested reader, however, is urged to consult the definitive article by Shore and Knight [10] for a comprehensive review of the first 30 years of Jaynes-Cummings physics. The collection of 26 papers presented in this issue, showcases a snapshot of some of the most recent and continuing research devoted to Jaynes-Cummings physics. We begin our special issue with Professor Cumming's recollections [11]. We then have six papers on quantum information aspects of the Jaynes-Cummings model [12-17]. The next topic includes seven papers on the Dicke and generalized Jaynes-Cummings models [18-24], followed by six papers on circuit QED, which is one of the most important experimental frameworks for Jaynes-Cummings systems [25-30]. Finally, we have six papers on the extension to many cavities, the Jaynes-Cummings-Hubbard model [31-36]. The snapshot of research captured in this special issue illustrates the unifying language provided by the Jaynes-Cummings model, tying together research in a number of

    Anniversaries call for celebrations. Since it is now fifty years since the first semiconductor lasers were reported, it is highly appropriate to celebrate this anniversary with a Special Issue dedicated to the topic. The semiconductor laser now has a major effect on our daily lives since it has been a key enabler in the development of optical fibre communications (and hence the internet and e-mail), optical storage (CDs, DVDs, etc) and barcode scanners. In the early 1960s it was impossible for most people (with the exception of very few visionaries) to foresee any of these future developments, and the first applications identified were for military purposes (range-finders, target markers, etc). Of course, many of the subsequent laser applications were made possible by developments in semiconductor materials, in the associated growth and fabrication technology, and in the increased understanding of the underlying fundamental physics. These developments continue today, so that the subject of semiconductor lasers, although mature, is in good health and continues to grow. Hence, we can be confident that the pervasive influence of semiconductor lasers will continue to develop as optoelectronics technology makes further advances into other sectors such as healthcare, security and a whole host of applications based on the global imperatives to reduce energy consumption, minimise environmental impact and conserve resources. The papers in this Special Issue are intended to tell some of the story of the last fifty years of laser development as well as to provide evidence of the current state of semiconductor laser research. Hence, there are a number of papers where the early developments are recalled by authors who played prominent parts in the story, followed by a selection of papers from authors who are active in today's exciting research. The twenty-fifth anniversary of the semiconductor laser was celebrated by the publication of a number of papers dealing with the early

    This particular 'Fusion Pioneers Memorial lecture' was given 50 years after the first historical FEC conference in 1958. It was a unique occasion to perform a global reflection on thermonuclear fusion which is summarized in this paper. We first consider the case for fusion energy then move on to the scientific achievements during the past five decades. Finally, the lessons drawn from the past give a framework to consider the challenges ahead of us. The 1958 pioneers had the vision of the vital importance of international collaboration to succeed in this unique endeavour. Fifty years later, this vision has amply proven its worth. Looking at the way forward, this vision constitutes a strong basis to harness fusion energy in the decades to come.

  11. Fifty years of hemodialysis access literature: The fifty most cited publications in the medical literature.

    2018-02-01

    Objectives The modern era of hemodialysis access surgery began with the publication in 1966 by Brescia et al. describing the use of a surgically created arteriovenous fistula. Since then, the number of patients on chronic hemodialysis and the number of publications dealing with hemodialysis access have steadily increased. We have chronicled the increase in publications in the medical literature dealing with hemodialysis access by evaluating the characteristics of the 50 most cited articles. Methods We queried the Science Citation Index from the years 1960-2014. Articles were selected based on a subject search and were ranked according to the number of times they were cited in the medical literature. Results The 50 most frequently cited articles were selected for further analysis and the number of annual publications was tracked. The landmark publication by Dr Brescia et al. was unequivocally the most cited article dealing with hemodialysis access (1109 citations). The subject matter of the papers included AV fistula and graft (9), hemodialysis catheter (9), complications and outcomes (24), and other topics (8). Most articles were published in nephrology journals (33), with fewer in surgery (7), medicine (7), and radiology (3) journals. Of the 17 journals represented, Kidney International was the clear leader, publishing 18 articles. There has been an exponential rise in the frequency of publications regarding dialysis access with 42 of 50 analyzed papers being authored after 1990. Conclusion As the number of patients on hemodialysis has increased dramatically over the past five decades, there has been a commensurate increase in the overall number of publications related to hemodialysis access.

    This unique volume summarizes with a historical perspective several of the major scientific achievements of Ludwig Faddeev, with a foreword by Nobel Laureate C N Yang. The volume that spans over fifty years of Faddeev's career begins where he started his own scientific research, in the subject of scattering theory and the three-body problem. It then continues to describe Faddeev's contributions to automorphic functions, followed by an extensive account of his many fundamental contributions to quantum field theory including his original article on ghosts with Popov. Faddeev's contributions to soliton theory and integrable models are then described, followed by a survey of his work on quantum groups. The final scientific section is devoted to Faddeev's contemporary research including articles on his long-term interest in constructing knotted solitons and understanding confinement. The volume concludes with his personal view on science and mathematical physics in particular.

A few witch prescriptions in Wushierbingfang ('Prescriptions for fifty-two diseases') indicated the residual traces of the mixture of witch and medicine in the medical literatures. The witch prescriptions recorded in Wushierbingfang ('Prescriptions for fifty-two diseases') could be divided into supplication, Yu-step, exorcism, Nuo ritual and peach wood charms etc. Witchcraft developed into folklore and the application of witchcraft sometimes manifested as the form of folklore, which were also reflected in the records of ('Prescriptions for fifty-two diseases').

    The processes of weather and climate, including the greenhouse effect and the potential for significant, even catastrophic human impacts on the climate system, were sufficiently understood in 1958 during the International Geophysical Year that the authors of the science education booklet, Planet Earth, The Mystery with 100,000 Clues, published by the U.S. National Academy of Sciences, were confident to predict that continued emissions of carbon dioxide into the atmosphere could, in time, melt icecaps and glaciers and rise sea levels. This important scientific insight was further studied by climatologists, but is largely missing as an integral, important component of science education. Now, fifty years later, with a global population that has doubled, fossil fuel emissions that have tripled, and current energy consumption and emission trajectories that are above the IPCC Business as Usual scenario, leading politicians still doubt that our global economy can impact the climate system. NRC estimates that up to 40 percent of the approximately $10 trillion U.S. economy is affected by weather and climate events annually, making it a crucial if not dominant factor in our economic well-being, particularly for future generations. Despite the long term and short term importance of climate in our lives, society is essentially illiterate about climate science and confused about the connections between energy, economy and climate, as numerous public opinion polls and studies have shown. A key reason is that education programs and pedagogical content knowledge focusing on the basics of climate, including natural variability as well as human induced climate change, are largely missing from K12 and undergraduate education. Climate has fallen through disciplinary cracks, been avoided because of perceived controversy, and neglected because most educators lack training or expertise in the subject matter. With a focus on climate in formal education, this paper will provide an overview

  15. The Proton Synchrotron, going strong at fifty years

    CERN Multimedia

    Django Manglunki

    It was on the evening of 24 November 1959 that an incredulous Hildred Blewett, on detachment to CERN from the Brookhaven laboratory, exclaimed “Yes! We’re through transition!” The first beam of ten billion protons had not only broken through the 5.2 GeV barrier but gone on all the way to 24 GeV, the machine’s top energy at that time.   An operational screenshot from the PS, taken on its 50th anniversary. The three white peaks depict different phases (cycles) of the PS’s operation. In the first and third cycle, the PS is producing a very low-intensity beam for LHC commissioning. In the second cycle, protons are being spilled out for use in the East Area. Fifty years ago the PS, the first strong-focusing proton synchrotron using alternating gradient technology, first began to circulate beams at an unprecedented level of energy. Over the years, a complex of linear and circular accelerators and storage rings grew up around the PS. In the mid-1990s ...

    Fifty years ago pioneering archaeologist Robert Suggs reported a small number of pottery sherds from the Marquesas Islands. The first such finds in East Polynesia, at the time they were considered indicative of both a Marquesan homeland and local ceramic manufacture. In the intervening years, additional sherds have been recovered from three other Marquesan localities resulting in a total of 14 specimens. Prior petrographic studies demonstrate unambiguously that some derive from Fiji. Others have been interpreted historically as representative of an indigenous Marquesan ceramic industry. Here we bring together key petrographic analyses from Polynesia, recent chronological assessments of the Marquesan sequence, and insights from new field research to reassess the origins and chronology of Marquesan pottery. We suggest that there is little support for an indigenous Marquesan ceramic industry, and most likely all of the specimens are imports. With respect to the timing of ceramic arrivals, three hypotheses are explored: 1) with founding settlers, 2) as a component of long-distance exchange networks operating between the 12th to 16th centuries AD, or 3) as late prehistoric or historic imports. The preponderance of evidence points to the second alternative, although the other two cannot be completely discounted for the assemblage as a whole. (author). 63 refs., 5 figs., 3 tabs.

    Fifty years of the Gastroenterological Society of Australia have witnessed the changing appearance of Australians. Asian immigration has transformed the dominant urban culture from European to Eurasian, with some unique Australian attributes. Meanwhile, global conditions have altered body shape, and our sports-proud country is now fat! Thus, as in North America, Europe, China, and affluent Asia-Pacific countries, prosperity and lifestyle, cheap processed foods coupled with reduced physical activity have created an epidemic of over-nutrition resulting in overweight/obesity. Additional genetic factors are at the core of the apple shape (central obesity) that typifies over-nourished persons with metabolic syndrome. Indigenous Australians, once the leanest and fittest humans, now have exceedingly high rates of obesity and type 2 diabetes, contributing to shorter life expectancy; Asian Australians are also at higher risk. Like non-steroidal anti-inflammatory drugs (NSAIDs) and cigarette smoking, obesity now contributes much to gastrointestinal morbidity and mortality (gastroesophageal reflux disease, cancers, gallstones, endoscopy complications). This review focuses on Australian research about fatty liver, particularly roles of central obesity/insulin resistance in non-alcoholic fatty liver disease/steatohepatitis (NAFLD/NASH). The outputs include many highly cited original articles and reviews and the first book on NAFLD. Studies have identified community prevalence, clinical outcomes, association with insulin resistance, metabolic syndrome and hypoadiponectinemia, developed and explored animal models for mechanisms of inflammation and fibrosis, conceptualized etiopathogenesis, and demonstrated that NASH can be reversed by lowering body weight and increasing physical activity. The findings have led to development of regional guidelines on NAFLD, the first internationally, and should now inform daily practice of gastroenterologists.

  18. Fifty Years of Space Weather Forecasting from Boulder

    Berger, T. E.

    2015-12-01

    The first official space weather forecast was issued by the Space Disturbances Laboratory in Boulder, Colorado, in 1965, ushering in an era of operational prediction that continues to this day. Today, the National Oceanic and Atmospheric Administration (NOAA) charters the Space Weather Prediction Center (SWPC) as one of the nine National Centers for Environmental Prediction (NCEP) to provide the nation's official watches, warnings, and alerts of space weather phenomena. SWPC is now integral to national and international efforts to predict space weather events, from the common and mild, to the rare and extreme, that can impact critical technological infrastructure. In 2012, the Strategic National Risk Assessment included extreme space weather events as low-to-medium probability phenomena that could, unlike any other meteorogical phenomena, have an impact on the government's ability to function. Recognizing this, the White House chartered the Office of Science and Technology Policy (OSTP) to produce the first comprehensive national strategy for the prediction, mitigation, and response to an extreme space weather event. The implementation of the National Strategy is ongoing with NOAA, its partners, and stakeholders concentrating on the goal of improving our ability to observe, model, and predict the onset and severity of space weather events. In addition, work continues with the research community to improve our understanding of the physical mechanisms - on the Sun, in the heliosphere, and in the Earth's magnetic field and upper atmosphere - of space weather as well as the effects on critical infrastructure such as electrical power transmission systems. In fifty years, people will hopefully look back at the history of operational space weather prediction and credit our efforts today with solidifying the necessary developments in observational systems, full-physics models of the entire Sun-Earth system, and tools for predicting the impacts to infrastructure to protect

    2009-01-01

    In 1959, the Korean Society for Parasitology was founded by clinical scientists, specialists of public health, and 5 core parasitologists with experience in American science and medicine. The Society this year celebrates its 50th anniversary. Due to public health importance at the time of foundation, medical parasitology was the main stream for next 3 decades. Domestic problems of niche parasitic diseases, unlisted in 6 tropical diseases of major importance, had been studied by own efforts. To cope with the demand of parasite control, evaluation system for control activity was built up. Control activity against soil-transmitted nematodes, conducted for almost 3 decades, was evaluated as a success. Evaluation of praziquantel efficacy for clonorchiasis, paragonimiasis, and neurocysticercosis, population dynamics of Ascaris lumbricoides infection in a situation of continuous reinfections, diagnostic modalities of antibody tests combined with brain imaging developed for helminthiasis of the central nervous system and researches on intestinal trematodes were achievements in the first 30 years. During the recent 2 decades, science researches, such as cell and molecular biology of parasites and immunology of parasitic infections have been studied especially on parasitic allergens and proteolytic and anti-oxidant enzymes. Experiences of international cooperation for world health have been accumulated and would be expanded in the future. PMID:19885338

    2002-01-01

    After the devastating floods caused by Hurricane Mitch in 1998, maps of the areas and depths of 50-year-flood inundation at 15 municipalities in Honduras were prepared as a tool for agencies involved in reconstruction and planning. This report, which is one in a series of 15, presents maps of areas in the municipality of Nacaome that would be inundated by 50-year floods on Rio Nacaome, Rio Grande, and Rio Guacirope. Geographic Information System (GIS) coverages of the flood inundation are available on a computer in the municipality of Nacaome as part of the Municipal GIS project and on the Internet at the Flood Hazard Mapping Web page (http://mitchnts1.cr.usgs.gov/projects/floodhazard.html). These coverages allow users to view the flood inundation in much more detail than is possible using the maps in this report. Water-surface elevations for 50-year-floods on Rio Nacaome, Rio Grande, and Rio Guacirope at Nacaome were computed using HEC-RAS, a one-dimensional, steady-flow, step-backwater computer program. The channel and floodplain cross sections used in HEC-RAS were developed from an airborne light-detection-and-ranging (LIDAR) topographic survey of the area and ground surveys at two bridges. The estimated 50-year-flood discharge for Rio Nacaome at Nacaome, 5,040 cubic meters per second, was computed as the drainage-area-adjusted weighted average of two independently estimated 50-year-flood discharges for the gaging station Rio Nacaome en Las Mercedes, located about 13 kilometers upstream from Nacaome. One of the discharges, 4,549 cubic meters per second, was estimated from a frequency analysis of the 16 years of peak-discharge record for the gage, and the other, 1,922 cubic meters per second, was estimated from a regression equation that relates the 50-year-flood discharge to drainage area and mean annual precipitation. The weighted-average of the two discharges is 3,770 cubic meters per second. The 50-year-flood discharges for Rio Grande, 3,890 cubic meters per

One discharge, 4,913 cubic meters per second, was estimated from a frequency analysis of the 17 years of peak discharge record for the gage, and the other, 2,650 cubic meters per second, was estimated from a regression equation that relates the 50-year-flood discharge to drainage area and mean annual precipitation. The weighted-average of the two discharges at the gage is 4,530 cubic meters per second. The 50-year-flood discharge for the study area reach of Rio Choluteca was estimated by multiplying the weighted discharge at the gage by the ratio of the drainage

    2007-01-01

    Paranthropus boisei is a hominin taxon with a distinctive cranial and dental morphology. Its hypodigm has been recovered from sites with good stratigraphic and chronological control, and for some morphological regions, such as the mandible and the mandibular dentition, the samples are not only relatively well dated, but they are, by paleontological standards, reasonably-sized. This means that researchers can trace the evolution of metric and nonmetric variables across hundreds of thousands of years. This paper is a detailed review of half a century's worth of fossil evidence and analysis of P. boisei and traces how both its evolutionary history and our understanding of its evolutionary history have evolved during the past 50 years.

    When dealing with acute laryngeal obstruction, the first important consideration is the differential diagnosis of the cause. The author considers the following six types: acute laryngotracheobronchitis, acute epiglottitis, diphtheria, supraglottic allergic edema (angioedema), subglottic allergic edema (spasmodic croup) and foreign body in the larynx or trachea. He traces the development of the treatments that have in 50 years lowered the mortality rate from 70% to practically zero. High humidity, best supplied by an ultrasonic nebulizer, antibiotics, and corticosteroids in very high dose have been the prime effective measures. There still is controversy about the choice between tracheostomy and nasotracheal intubation if medical therapy is delayed or ineffective. The primary physician must know when and where to send these children in order to prevent the fatalities so frequent in previous years.

  13. Fifty Years of Boundary-Layer Theory and Experiment

    Science.gov (United States)

    Dryden, Hugh L.

    1955-01-01

    The year 1954 marked the 50th anniversary of the Prandtl boundary-layer theory from which we may date the beginning of man's understanding of the dynamics of real fluids. A backward look at this aspect of the history of the last 50 years may be instructive. This paper (1) attempts to compress the events of those 50 years into a few thousand words, to tell in this brief space the interesting story of the development of a new concept, its slow acceptance and growth, its spread from group to group within its country of origin, and its diffusion to other countries of the world. The original brief paper of Prandtl (2) was presented at the Third International Mathematical Congress at Heidelberg in 1904 and published in the following year. It was an attempt to explain the d'Alembert paradox, namely, that the neglect of the small friction of air in the theory resulted in the prediction of zero resistance to motion. Prandtl set himself the task of computing the motion of a fluid of small friction, so small that its effect could be neglected everywhere except where large velocity differences were present or a cumulative effect of friction occurred This led to the concept of boundary layer, or transition layer, near the wall of a body immersed in a fluid stream in which the velocity rises from zero to the free-stream value. It is interesting that Prandtl used the term Grenzsehicht (boundary layer) only once and the term Ubergangsschicht (transition layer) seven times in the brief article. Later writers also used Reibungsschicht (friction layer), but most writers today use Grenzschicht (boundary layer).

  14. REVIEW: Fifty years of Monte Carlo simulations for medical physics

    Science.gov (United States)

    Rogers, D. W. O.

    2006-07-01

    Monte Carlo techniques have become ubiquitous in medical physics over the last 50 years with a doubling of papers on the subject every 5 years between the first PMB paper in 1967 and 2000 when the numbers levelled off. While recognizing the many other roles that Monte Carlo techniques have played in medical physics, this review emphasizes techniques for electron-photon transport simulations. The broad range of codes available is mentioned but there is special emphasis on the EGS4/EGSnrc code system which the author has helped develop for 25 years. The importance of the 1987 Erice Summer School on Monte Carlo techniques is highlighted. As an illustrative example of the role Monte Carlo techniques have played, the history of the correction for wall attenuation and scatter in an ion chamber is presented as it demonstrates the interplay between a specific problem and the development of tools to solve the problem which in turn leads to applications in other areas. This paper is dedicated to W Ralph Nelson and to the memory of Martin J Berger, two men who have left indelible marks on the field of Monte Carlo simulation of electron-photon transport.

    Skoog, A. Ingemar; Hall, R. Cargill

    2017-05-01

    The International Academy of Astronautics (IAA) Symposia on the History of Rocketry and Astronautics have been held annually at the International Astronautical Congresses since 1967. During these past 50 years nearly 800 papers have been presented and subsequently published in the proceedings. With a 20-year rule imposed for historical presentations, the first 10 symposia concentrated on pre-World War II and early 1950s activities. A surprisingly large number of papers on early, less well-known Soviet-Russian contributions to rocketry and astronautics were presented in the first symposia, despite the ongoing Space Race between the U.S and USSR. Another important element in these symposia involved memoir papers offered by pre- and post-war rocket and astronautics pioneers from many countries, and the participation of many of these pioneers in person. In sum, the history of national space and rocket projects from some 40 countries were presented over the years in IAA History Symposia. These 50 symposia have provided a platform for scholars and professional and non-professional historians to meet and discuss the history of rocketry and astronautics, and to personally interview many space pioneers, most of whom today are deceased. Their personal recollections have since been shared with a large audience. Over time, IAA history papers divided into recognizable periods: ancient times through the 19th century, and the 20th and 21st centuries, which separate among actions and events that took place before 1945, in 1945 to 1957, and after 1957 (which marked the beginning of the space age). Proceedings of the IAA History Symposia have been published in English, ultimately in the History Series of the American Astronautical Society (AAS) and its publishing arm, Univelt Inc., under an agreement secured with the IAA. This paper presents an overview of the IAA History Symposia. It examines the early years of the history committee and its first symposium, the evolution of

  18. Changes in sunflower breeding over the last fifty years

    Directory of Open Access Journals (Sweden)

    Vear Felicity

    2016-03-01

    Full Text Available This article discusses changes in sunflower breeding objectives since the introduction of hybrid varieties 50 years ago. After a reminder of the importance of some early programmes, Canadian in particular, the present situation for each breeding objective is compared with those encountered earlier. Breeding for yield has changed from maximum possible yield under intensive agriculture to yield with resistance to abiotic stresses, moderate droughts and shallow soils in particular, helped by collaboration with agronomists to produce crop models. Breeding for oil has changed from quantity to quality and the value of seed meal is again becoming economically important. Necessary disease resistances vary with agronomic practises and selection pressure on pathogens according to varietal genetics. The possibilities of new types of sunflower are also discussed. Advances in genomics will change breeding procedures, but with rapidly changing molecular techniques, international collaboration is particularly important.

    Erving Goffman's "Asylums" is a key text in the development of contemporary, community-orientated mental health practice. It has survived as a trenchant critique of the asylum as total institution, and its publication in 1961 in book form marked a further stage in the discrediting of the asylum model of mental health care. In this paper, some responses from a range of disciplines to this text, 50 years on, are presented. A consultant psychiatrist with a special interest in cultural psychiatry and mental health legislation, two collaborating psychotherapists in adult and forensic mental health, a philosopher, and a recent medical graduate, present their varying responses to the text. The editors present these with the hope of encouraging further dialogue and debate from service users, carers, clinicians, and academics and researchers across a range of disciplines.

    Melphalan remains the most widely used agent in preparative regimens for hematopoietic stem-cell transplantation. From its initial discovery more than 50 years ago, it has been gradually incorporated in the conditioning regimens for both autologous and allogeneic transplantation due to its myeloablative properties and broad antitumor effects as a DNA alkylating agent. Melphalan remains the mainstay conditioning for multiple myeloma and lymphomas; and has been used successfully in preparative regimens of a variety of other hematological and non-hematological malignancies. The addition of newer agents to conditioning like bortezomib or lenalidomide for myeloma, or clofarabine for myeloid malignancies, may improve antitumor effects for transplantation, while in combination with alemtuzumab may represent a backbone for future cellular therapy due to reliable engraftment and low toxicity profile. This review summarizes the development and the current use of this remarkable drug in hematopoietic stem-cell transplantation. PMID:22922522

    1997-04-01

    This report provides a chronological history of policies and practices relating to the management of radioactive waste for which the US Atomic Energy Commission and its successor agencies, the Energy Research and Development Administration and the Department of Energy, have been responsible since the enactment of the Atomic Energy Act in 1946. The defense programs and capabilities that the Commission inherited in 1947 are briefly described. The Commission undertook a dramatic expansion nationwide of its physical facilities and program capabilities over the five years beginning in 1947. While the nuclear defense activities continued to be a major portion of the Atomic Energy Commission's program, there was added in 1955 the Atoms for Peace program that spawned a multiplicity of peaceful use applications for nuclear energy, e.g., the civilian nuclear power program and its associated nuclear fuel cycle; a variety of industrial applications; and medical research, diagnostic, and therapeutic applications. All of these nuclear programs and activities generated large volumes of radioactive waste that had to be managed in a manner that was safe for the workers, the public, and the environment. The management of these materials, which varied significantly in their physical, chemical, and radiological characteristics, involved to varying degrees the following phases of the waste management system life cycle: waste characterization, storage, treatment, and disposal, with appropriate transportation linkages. One of the benefits of reviewing the history of the waste management program policies and practices if the opportunity it provides for identifying the lessons learned over the years. Examples are summarized at the end of the report and are listed in no particular order of importance

  3. Nuclear chemistry fifty years after the discovery of artificial radioactivity

    1984-01-01

    In January 1934, the observation and the chemical identification of radiophosphorus as a reaction product in the bombardment of Aluminium by alpha particles have been the first step of a new scientific branch: Nuclear Chemistry. We describe here how this discovery in itself contains the frame of all the development which has followed. It consisted in four stages, each of them being a crucial starting point. The first one is the possibility for a total balance of the nuclear reaction in the exit channels, so that reaction mechanisms can be studied. The second, the most important perhaps, is the opening of nuclear synthesis. Nuclear chemists can now interfere into nuclear matter and instead of staying as observers of the radioactive decays of natural isotopes, they were able to build up a numerous chart of various nuclear species, going step by step further and further away from the nuclear stability conditions. The third aspect of the discovery was the appearance of a new mode of radioactive decay with the production of the first particle an antimater. 50 years later, the instability due to a much larger excess of protons is known to induce the proton emission radioactivity for new species like 109 I or 115 Cs, in the vicinity of proton unstability. Finally, the last point, so fertile for the future, was the observation of a neutron in the exit channel, so that neutron fluxes could result from alpha induced nuclear reactions and became such a strong tool for the production of transuranium elements and for nuclear fission. In the present survey, the wide interest of the second point, i.e. the nuclear synthesis, is emphasized, as well as the huge change in the technical methods

  4. Fifty-one Years of Hawaiian Hotspot Debate

    Tuzo Wilson's ground breaking realization that the progressively increasing ages of volcanism along linear chains of Pacific islands are best explained by movement of the Pacific plate over a stationary heat source was followed by Jason Morgan's physically more plausible plume theory. Hawaii, the "mother" of all plumes/hotspots, has become the focus of a continuing burden-of-proof battle about the existence of mantle plumes. The monotonic age progression of this island chain has been amply confirmed, but the hotspot locus is not perfectly fixed, and this has been taken to be a failed test of the plume model. Numerous numerical experiments in bottom-heated settings have demonstrated that plumes are a physically natural mode of convection, but antiplumers focus on the fact that in internally heated media, plumes are unlikely. Early proposals of propagating lithospheric fractures with magma tapped from the underlying asthenosphere have never been sufficiently developed to seriously compete with the convection models. Geochemists eagerly adopted the plume model and developed highly model-dependent criteria for identifying mantle plumes, but these are easily knocked down, because most geochemical tracers carry no information about the specific mantle depth being sampled. Conversely, petrological-geochemical models invoking exclusively asthenospheric magma sources have not explained how, in the absence of a Bunsen burner, high melt production can be localized in one geographic spot for 108 years. Our work has focussed on using dynamic modelling to trace the path of geochemical heterogeneities from the base of the mantle to the volcanoes. We find that large-scale heterogeneities existing in the lower thermal boundary layer are drawn into close proximity in the plume conduit and in the erupting volcanoes. Geochemistry cannot prove mantle plumes, but plumes offer a promising path to understanding the geochemistry of the deep mantle.

  5. Fifty Years of THERP and Human Reliability Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Ronald L. Boring

    2012-06-01

    In 1962 at a Human Factors Society symposium, Alan Swain presented a paper introducing a Technique for Human Error Rate Prediction (THERP). This was followed in 1963 by a Sandia Laboratories monograph outlining basic human error quantification using THERP and, in 1964, by a special journal edition of Human Factors on quantification of human performance. Throughout the 1960s, Swain and his colleagues focused on collecting human performance data for the Sandia Human Error Rate Bank (SHERB), primarily in connection with supporting the reliability of nuclear weapons assembly in the US. In 1969, Swain met with Jens Rasmussen of Risø National Laboratory and discussed the applicability of THERP to nuclear power applications. By 1975, in WASH-1400, Swain had articulated the use of THERP for nuclear power applications, and the approach was finalized in the watershed publication of the NUREG/CR-1278 in 1983. THERP is now 50 years old, and remains the most well known and most widely used HRA method. In this paper, the author discusses the history of THERP, based on published reports and personal communication and interviews with Swain. The author also outlines the significance of THERP. The foundations of human reliability analysis are found in THERP: human failure events, task analysis, performance shaping factors, human error probabilities, dependence, event trees, recovery, and pre- and post-initiating events were all introduced in THERP. While THERP is not without its detractors, and it is showing signs of its age in the face of newer technological applications, the longevity of THERP is a testament of its tremendous significance. THERP started the field of human reliability analysis. This paper concludes with a discussion of THERP in the context of newer methods, which can be seen as extensions of or departures from Swain’s pioneering work.

    The great library of Alexandria may have contained fewer volumes than the number which have been written on the subject of nuclear weapons in the Cold War. With the end of the Cold War, a new nuclear library is in the making. Much thought is being given to the next steps in nuclear policy, strategy, forces, arms control, and nonproliferation. For this very distinguished conference, however, I have been asked to look further ahead indeed, forward fifty-years. Prognostication is always a risky business. Detailed predictions beyond the shortest duration are difficult to label as ``scientific`` even in the social sciences. Forecasting ahead fifty years in an age of ever accelerating change would seem to be hopeless. Projecting the future of nuclear weapons, however, may not be as complex as one might think. Detailing the future fifty years from now is not necessary. We want to inform upcoming decisions by examining the possibilities, not write a history in advance of what is to happen. Our look forward con benefit from a brief look back fifty years. In retrospect, those years passed quickly, and with each additional year, analysts make them appear more simple than they seemed at the time. This paper contributes further to this process of oversimplification, as we say, ``for heuristic purposes.`` When in doubt, I have erred on the side of being provocative.

In the 1950's papers on arthropods of medical importance were dominant, in the 1960's there was a poliferation of papers on bees, and in more recent years the subjects have become increasingly diverse. In terms of nationality of contributing authors, the journal appears to have become increasingly international in later years.

    Nuclear engineering education has been initiated in 1957 at the graduate school of Tokyo Institute of Technology. Educational activities have been conducted for fifty years under the support of the Research Laboratory for Nuclear Reactors. In the past fifty years, about 1000 Master students and 200 Doctoral students and 200 Doctoral students graduated from our Nuclear Engineering Department at Tokyo Institute of Technology. Many of them found their jobs in nuclear industries and institutes. International course of nuclear engineering was initiated in 1994, and so far about 90 students from 15 overseas countries have graduated from our Master and Doctoral Programs. In 2003, our proposal of 'Innovative Nuclear Energy System for the Sustainable World' was adopted as the Center of Excellent Program sponsored by Ministry of Education, Science and Technology. Recently a collaborative education network has been developed among Kanazawa University, Fukui University, Ibaraki University, Okayama University, Tokyo Institute of Technology and Japan Atomic Energy Agency.

  1. Fifty years of fat: news coverage of trends that predate obesity prevalence.

    2015-07-10

    Obesity prevalence has risen in fifty years. While people generally expect media mentions of health risks like obesity prevalence to follow health risk trends, food consumption trends may precede obesity prevalence trends. Therefore, this research investigates whether media mentions of food predate obesity prevalence. Fifty years of non-advertising articles in the New York Times (and 17 years for the London Times) are coded for the mention of less healthy (5 salty and 5 sweet snacks) and healthy (5 fruits and 5 vegetables) food items by year and then associated with annual obesity prevalence in subsequent years. Time-series generalized linear models test whether food-related mentions predate or postdate obesity prevalence in each country. United States obesity prevalence is positively associated with New York Times mentions of sweet snacks (b = 55.2, CI = 42.4 to 68.1, p = .000) and negatively associated with mentions of fruits (b = -71.28, CI -91.5 to -51.1, p = .000) and vegetables (b = -13.6, CI = -17.5 to -9.6, p = .000). Similar results are found for the United Kingdom and The London Times. Importantly, the "obesity followed mentions" models are stronger than the "obesity preceded mentions" models. It may be possible to estimate a nation's future obesity prevalence (e.g., three years from now) based on how frequently national media mention sweet snacks (positively related) and vegetables or fruits (negatively related) today. This may provide public health officials and epidemiologists with new tools to more quickly assess the effectiveness of current obesity interventions based on what is mentioned in the media today.

    During the past 50 years the border area between psychiatry and somatic medicine has undergone remarkable changes. Theories have become better-founded, both psychologically and neurobiologically, research has become more sophisticated, and liaison-psychiatrists and health psychiatrist/behavioural medicine psychologists have played an increasingly active role in this domain. At the beginning of the 21st century modern psychosomatic medicine is facing new challenges; these include how to create a workable diagnostic classification system, how to instruct and educate both health professionals and lay-persons to an adequate level, how to utilize innovative research paradigms without having recourse to reductionism and how to implement in medical practice treatments that are geared to the needs of the individual patient.

    Rizzoli, P. M.

    2017-12-01

    Fifty years ago Venice and its lagoon suffered the most devastating flood in their millennial history. The causes of the increasingly recurring floods will be examined, namely the man-induced subsidence in the period 1925-1970 and the storm surges of the Adriatic sea. The engineering solution designed for their protection , named the MOSE system, will be discussed in detail. The MOSE was started in 2003 and is near completion. It consists of four barriers , invisible in normal conditions, which will close the inlets to the lagoon under the prediction of a forthcoming flood. Finally, the perspective of the MOSE capability of protecting the city under scenarios of future global sea level rise will be assessed. This assessment must critically take into account that Venice and its lagoon are confined in the northernmost corner of the semi-enclosed, marginal Mediterranean sea for which the uncertainties of future sea level rise greatly exceed the uncertainties of the global averages.

    Gauge evolution of the elementary particle physics has been remarked by outstanding and exiting discoveries during the last fifty years of X X century. We review a new tendency in the development of the modern elementary particle physics. The phenomenological basis for the formulation of Standard Model has been reviewed. The Standard Model based on the fundamental postulates has been formulated. The concept of the fundamental symmetries has been introduced to look for not fundamental particles but fundamental symmetries. The Standard Model is renormalizable and therefore potentially consistent in all energy scales. The Standard Model in principle can describe the properties of the Universe beginning at 10 -43 sec. after Big Bang. In searching of more general theory obvious program is to searching the first of all global symmetries and then learn consequences connected with the localization of these global symmetries

    1998-01-01

    A review of Amoco's first fifty years of operations in Canada, including investments, discoveries, and policies was presented. While no claim is made for this attractively produced slim volume to be a definitive history, it does manage to shed light on some of the great achievements and outstanding deeds of the people behind the company. The book provides a glimpse into how Amoco contributed to the growth of the Canadian petroleum industry in diverse areas including the manufacturing sector, the petroleum service sector, oil field technology, oil field infrastructure and petrochemical development. The company enjoyed spectacular success during the 1950s and 1960s. As evidence of that success, in 1997 Amoco Canada was the largest Canadian producer and exporter of natural gas and NGLs, the largest cold producer of heavy oil, the second largest in situ producer of heavy oil, and one of the 10 largest producers of conventional oil. refs., tabs., figs

  8. FOREWORD: Fifty years of atomic time-keeping: 1955 to 2005

    2005-06-01

    The year 2005 is the centenary of Einstein's four famous papers that were published in 1905. This anniversary is being widely celebrated all over the world and, indeed, 2005 has been dubbed World Year of Physics. The year 2005, however, also marks the fiftieth anniversary of the first operation of Essen and Parry's caesium beam atomic frequency standard at the NPL in May 1955. While Einstein's papers signalled a revolution in physics and in our understanding of the natural world, the first atomic clock signalled a revolution in time-keeping that has become, among other things, one of the most powerful tools in pushing back the frontiers of Einstein's theories of special and general relativity. The atomic clock has also had consequences for navigation comparable to those brought about by Harrison's mechanical clocks almost exactly two hundred years before. Harrison's H3 was completed in 1757 and H4 in 1759. The atomic clock, and the creation of an atomic time scale that quickly followed, led ten years later to the adoption of an atomic definition for the SI second in Resolution 1 of the 13th General Conference on Weights and Measures, 1967/68. This marked the end of time-keeping based on the movements of the heavenly bodies that had beaten the rhythm of the days and the seasons since the dawn of human civilization. Fifty years on is a good occasion to look back, to look forward and at the same time to examine where we are today, in terms of measuring time. While we still arrange for our atomic clocks to show noon when the sun is overhead on the Greenwich meridian, everything else has changed in the fifty years since 1955.

    Fifty years after Ehrlich and Raven's seminal paper, the idea of co-evolution continues to grow as a key concept in our understanding of organic evolution. This concept has not only provided a compelling synthesis between evolutionary biology and community ecology, but has also inspired research that extends beyond its original scope. In this article, we identify unresolved questions about the co-evolutionary process and advocate for the integration of co-evolutionary research from molecular to interspecific interactions. We address two basic questions: (i) What is co-evolution and how common is it? (ii) What is the unit of co-evolution? Both questions aim to explore the heart of the co-evolutionary process. Despite the claim that co-evolution is ubiquitous, we argue that there is in fact little evidence to support the view that reciprocal natural selection and coadaptation are common in nature. We also challenge the traditional view that co-evolution only occurs between traits of interacting species. Co-evolution has the potential to explain evolutionary processes and patterns that result from intra- and intermolecular biochemical interactions within cells, intergenomic interactions (e.g. nuclear-cytoplasmic) within species, as well as intergenomic interactions mediated by phenotypic traits between species. Research that bridges across these levels of organization will help to advance our understanding of the importance of the co-evolutionary processes in shaping the diversity of life on Earth. © 2015 John Wiley & Sons Ltd.

  10. Fifty years of herbicide research: comparing the discovery of trifluralin and halauxifen-methyl.

    Fifty years separate the commercialization of the herbicides trifluralin and halauxifen-methyl. Despite the vast degree of technological change that occurred over that time frame, some aspects of their discovery stories are remarkably similar. For example, both herbicides were prepared very early in the iterative discovery process and both were developed from known lead compound structures by hypothesis-driven research efforts without the use of in vitro assays or computer-aided molecular design. However, there are aspects of the halauxifen-methyl and trifluralin discovery stories that are substantially different. For example, the chemical technology required for the cost-effective production of halauxifen-methyl simply did not exist just two decades prior to its commercial launch. By contrast, the chemical technology required for the cost-effective production of trifluralin was reported in the chemical literature more than two decades prior to its commercial launch. In addition, changes in regulatory environment since the early 1960s ensured that their respective discovery to commercial launch stories would also differ in substantial ways. Ultimately, the time and cost required to develop and register halauxifen-methyl demanded a global initial business case while the lower registration hurdles that trifluralin cleared enabled a narrow initial business case mainly focused on the USA. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  12. Cecilia Payne-Gaposchkin, Henry Norris Russell Lecture: Fifty Years of Novae

    Burbidge, E. M.

    1999-05-01

    It is easy to pick out my most memorable meeting of the AAS: the 149th meeting held in January, 1977, and hosted by the University of Hawaii, in Honolulu, HI. It was the meeting at which two traditions of the Society were broken, and we moved into the era of equal opportunity for women astronomers. Cecilia Payne-Gaposchkin received the highest award of the AAS: the Henry Norris Russell Lectureship. This award had never before been available to women, otherwise Cecilia would, years earlier, have been honored for the many achievements in her lifetime of renowned astronomical research. And I, the first woman to be elected President of the AAS, had the honor of presenting the illuminated scroll to Cecilia, and of introducing her on the platform where she delivered the Henry Norris Russell Prize Lecture, entitled ``Fifty Years of Novae"(1) . Cecilia opened by comparing the experience of young and old scientists in achieving exciting results from their research, and then led us through the history of the discoveries of and about some famous novae. She described the physical picture that emerged from studies of their light curves, their spectra, and the discovery of their binary nature. Three important tables were included, listing data on cataclysmic binaries (dwarf novae) and their link to the nova phenomenon in general. She recalled that she and Sergei Gaposchkin had hesitated between the names catastrophic and cataclysmic for the dwarf novae, and decided on the latter, from the dictionary definitions of those two terms: ``a cataclysm is a great and general flood" while a catastrophe ``is a final event". The nova phenomenon is recurrent, as are the dwarf novae, and both involve an outpouring of a flood of energy. She concluded by describing her 50 years' experience with novae as presenting ``the contemporary portrait of a nova", rather than a final picture, and by forecasting that the next 50 years of discovering and studying novae will be as full of surprises as the

    Full Text Available This paper illustrates the results of an analysis performed on historical data of the main meteorological and water quality variables collected during the last fifty years in the basin of Lake Trasimeno, a shallow lake subjected to important water level fluctuations. The results reveal a significant increase of the annual mean of minimum and maximum air temperature, water temperature and solar radiation, and a significant reduction of precipitation and cloud cover, which have mostly occurred during the last twenty years. The decadal rate of warming observed in the last twenty years for air temperature (0.33 °C decade-1 is consistent with the estimate reported by the IPCC for the land-surface temperature in the Northern Hemisphere, whereas the surface water temperature in Lake Trasimeno shows a more marked increase (0.65 °C decade-1, comparable to that observed in other lakes of Mediterranean areas. On a monthly scale, the most significant variations are observed in late-spring and early summer months for temperature and solar irradiation, and in winter and spring months for rainfall, which result in an appreciable modification of the seasonal progression. The alterations of the thermal and hydrological balance of the lake have caused a progressive lowering of the water level and the emergence of evaporative conditions. As a consequence of the drought, a progressive accumulation of dissolved salts (3.5 106 kg y-1 is observed, which is partially explained by meteoric loading. The analysis also shows that an increase in the total alkalinity has occurred during the main drought phases of the last forty years, which has been shown to be consistent with what expected on the basis of the changes in the ionic composition of the waters. With decreasing water levels, a strong reduction in water transparency has also been observed, which does not appear to be connected with a change in the trophic state of the lake, but rather with the increase of

    2000-07-01

    Few people realize that Canada leads in the world in the production of radio isotopes, the raw material of nuclear medicine and high-tech scanners, and in their use in medicine and industry. In Isotopes and Innovation the author gives an in-depth look at MDS Nordion, a company that started as the radium sales department of Eldorado Mining and Refining, the Canadian uranium producer that was a key strategic resource for the Allies during the race to build the nuclear bomb, and went on to become the world?s leading producer of radioisotopes. When radium began to be used as a cancer treatment, Eldorado quickly became familiar with the medical marketplace and adept at developing products that could solve clinical problems and, more important, save lives. When Canadian nuclear reactors at Chalk River began producing radioisotopes that outperformed radium, Eldorado's radium sales department was transferred to a new crown corporation, Atomic Energy of Canada Limited, created to manage Canada's nuclear research establishment. The new company developed many useful applications for radioisotopes, including cobalt-60 cancer therapy machines and industrial sterilization plants. Bought by Medical Data Services Inc. in the early 1990s, MDS Nordion was a runaway success, creator and sole proprietor of several market-leading products. Isotopes and Innovation describes how a company capitalized on the byproducts of Canada's unique nuclear research program to attain a commanding international position in extremely specialized and demanding high-tech markets, a saga in which innovative research and enterprising global marketing have brought commercial success and saved countless lives around the world.

    Introduces the current issue of the American Psychologist, which examines the ramifications of the Brown vs. Board of Education decision and its sequelae over the last 50 years, with a special focus on the mixed role of psychological research and practice. Despite the great strides toward a more just society since May 17, 1954, inequities remain in schooling, in social relations, and in economic opportunity. How will history judge American psychology 50 years from now vis-a-vis the possibilities it helped create via Brown? The articles in this special issue suggest several important directions of research and action our field will need to take if the verdict of history is to be a positive one.

    Widely regarded as a revolutionary drug in its early years, "the pill" may be considered the first designer or lifestyle drug. Approximately 85% of women in the United States will use an oral contraceptive (OC) for an average of 5 years. Since the introduction of OCs in the 1960s, both health benefits and safety concerns have been attributed to their use. Widespread use of OC formulations by women throughout their reproductive life cycle gave rise to concerns about the effects of OCs on risk factors for cardiovascular disorders and cancer. In most instances, the noncontraceptive benefits of OCs outweigh the potential risks. As with many first in class drugs, lessons can be learned from its development and use. Indeed, "the pill" played a significant role in reshaping the regulatory process for new drugs during the second half of the 20th century. The birth control pill celebrates its 50th birthday this year, as women and men celebrate five decades of this revolutionary method of family planning. Recent scientific and technological advances in genomics, proteomics, new materials, and new drug delivery systems, along with a new understanding of reproductive biology, offer the promise of new, safe, and effective forms of contraception. In addition to the history of OC therapeutic advances and unintended side effects, the noncontraceptive health benefits that women experience beyond pregnancy prevention are discussed. This article summarizes a symposium presented at the 50th Anniversary of the Society of Toxicology National Meeting, held from 6 to 10 March 2011 in Washington, DC.

  10. Total body irradiation prior to bone marrow transplantation; some aspects of fifty year experience.

    Gocheva, L

    2004-01-01

    There has been a remarkable growth in the use of bone marrow transplantation (BMT) in the past 30 years. The rapid expansion of BMT reflects its increasingly important role in the treatment of several life-threatening diseases of the hemopoietic system. The first BMT in human patients was performed after conditioning with total body irradiation (TBI). As an important part of BMT protocols, TBI has an established role in many preparative regimens used before BMT in the treatment of hematological diseases. Historically, TBI schedules varied during the last 30-year period with regard to different radiation source used, treatment technique, beam modifiers, actually delivered total dose, dose rate, and fractionation schedule. The aim of this review article is to discuss the 50- year experience in the field of TBI, as well as radiobiological, technical and dosimetric requirements and especially effects of total dose, dose rate and fractionation schedules on the prognosis of transplanted patients. The radiobiological and radio-oncological requirements demand special TBI treatment techniques quite different from usual radiotherapy. The technique needed depends extremely on the prescribed values of treatment parameters and on the local technical possibilities. TBI dosimetry has to account for the physical situation of treatment with very large field sizes at extended distances and should be performed under TBI conditions close to the real treatment situation. The effects of total dose, dose rate, fractionation schedule on the leukemia cell killing, immunosuppression, and sparing of normal tissues are considered in detail. Their effects on overall survival, leukemia recurrence, acute and chronic graft versus host disease (GvHD), late radiation-induced injuries to normal tissues or organs as well as incidence of interstitial pneumonitis, renal dysfunction and cataract development are analyzed. The definition of currently used TBI procedures is so different in different

    From the moment Max Hamilton started his psychiatric education, he considered psychometrics to be a scientific discipline on a par with biochemistry or pharmacology in clinical research. His clinimetric skills were in operation in the 1950s when randomised clinical trials were established as the method for the evaluation of the clinical effects of psychotropic drugs. Inspired by Eysenck, Hamilton took the long route around factor analysis in order to qualify his scales for anxiety (HAM-A) and depression (HAM-D) as scientific tools. From the moment when, 50 years ago, Hamilton published his first placebo-controlled trial with an experimental anti-anxiety drug, he realized the dialectic problem in using the total score on HAM-A as a sufficient statistic for the measurement of outcome. This dialectic problem has been investigated for more than 50 years with different types of factor analyses without success. Using modern psychometric methods, the solution to this problem is a simple matter of reallocating the Hamilton scale items according to the scientific hypothesis under examination. Hamilton's original intention, to measure the global burden of the symptoms experienced by the patients with affective disorders, is in agreement with the DSM-IV and ICD-10 classification systems. Scale reliability and obtainment of valid information from patients and their relatives were the most important clinimetric innovations to be developed by Hamilton. Max Hamilton therefore belongs to the very exclusive family of eminent physicians celebrated by this journal with a tribute. 2009 S. Karger AG, Basel.

  14. White paper on science and technology, 1995. Fifty years of postwar science and technology in Japan

    International Nuclear Information System (INIS)

    1995-07-01

    This August marks 50 years since the end of World War II. Japan emerged from the ruins to overcome the post-war devastation to achieve a high level of economic growth and become the second largest economy in the world. Science and technology have played major roles as a driving force behind this quest for prosperity. However, it seems as though true prosperity is not necessarily being enjoyed by citizens of Japan today. Japan is becoming an aging society. To realize a truly rich and prosperous society in which people can live comfortably, it is important to further raise the level of science and technology. It is also necessary to ensure this development by revitalizing the economy, and to continue to utilize science and technology as an endless resource to create assets for society as a whole which will be inherited by future generations. With this viewpoint in mind, this White Paper looks back on Japan's scientific and technological development over the last 50 years, and considers the future of science and technology with a view toward realizing the true prosperity for its people. It is our hope that this White Paper will be helpful for considering the scientific and technological activities needed to bring about a Japan whose people are truly prosperous, and we will, as a government, continually increase our efforts toward the promotion of science and technology.

    2018-03-01

    More than 50 years ago, Shriners Hospitals for Children expanded their philanthropy to include care for burned children. In so doing, the effects of their work weightily expanded from rehabilitation and quality of life outcomes to include survival proper. As the first facility dedicated to the care of burned children, originally designated the Shriners Burn Institute, the Galveston hospital remains the cornerstone of this endeavor. Shriners maintains charitable pediatric hospitals, provide care irrespective of the patient's or the family's ability to pay, and promote research. The sole criterion for admission at Shriners Hospitals for Children is the determination by a surgeon at a Shriners hospital that "the child's trouble may be corrected or improved." This philanthropic effort to provide medical care for children is one expression of the human commonality recognized by Shriners. In this article, we provide some background information on how this hospital came into existence as well as a global summary of its interventions toward greater survival and more complete rehabilitation of burned children. Based on the findings presented herein, we assert that there is less suffering and less loss of life due to childhood burns today than in previous years. We attribute much of this improvement to the simple voluntary collective decision by Shriners to provide alms for burned children.

    The region north of the Garlock Fault between the Sierra Nevada and Death Valley has experienced at least eight Mw ≥ 6 earthquakes in historical times, beginning with the 1872, Mw 7.5, Owens Valley earthquake. Furthermore, since 1978, the Long Valley Caldera has been undergoing periods of unrest, with earthquake swarms and resurgence. Our goal is to determine whether the 1872 Owens Valley earthquake and the caldera unrest have influenced the evolution of seismicity in the area. We model the evolution of coseismic, postseismic, and interseismic Coulomb stress change (Coulomb failure stress (ΔCFS)) in the region due to both Mw ≥ 6 earthquakes and caldera inflation in the last 150 years. Our results show that the 1872 Owens Valley earthquake has an important influence on subsequent events, strongly encouraging faulting in northern Owens Valley while inhibiting it elsewhere. There is also a correlation between caldera inflation and seismicity in northern Owens Valley, evidenced by the west-to-east migration of earthquakes from the Long Valley Caldera toward the White Mountains immediately following the 1978 caldera inflation event. Finally, we show that a total ΔCFS increase of up to 30 bars in the last 150 years has occurred on part of the White Mountains fault, making it a possible candidate for the next major earthquake in this region.

Therefore, in this article we expose an historical and social tour of 50 years of the Instituto Mexicano del Seguro Social's library services in Puebla. From 1964 to 2014 occurred many events in the development of these services in our area, from the creation of a small space in the basement, to the implementation of spaces created deliberately to provide dignified service to all users, which is why this historical sketch is here as an acknowledgement to the first librarians who contributed to the training of specialists in Mexico.

    Half a century ago, the term "computer-aided diagnosis" (CAD) was introduced in the scientific literature. Pulmonary imaging, with chest radiography and computed tomography, has always been one of the focus areas in this field. In this study, I describe how machine learning became the dominant technology for tackling CAD in the lungs, generally producing better results than do classical rule-based approaches, and how the field is now rapidly changing: in the last few years, we have seen how even better results can be obtained with deep learning. The key differences among rule-based processing, machine learning, and deep learning are summarized and illustrated for various applications of CAD in the chest.

    Today, the Hanford Site is engaged in the largest waste cleanup effort ever undertaken in human history. That in itself makes the endeavor historic and unique. The Hanford Site has been designated the ''flagship'' of Department of Energy (DOE) waste remediation endeavors. And, just as the wartime Hanford Project remains unmatched in history, no counterpart exists for the current waste cleanup enterprise. This report provides a summary of the extensive historical record, however, which does give a partial road map. The science of environmental monitoring pioneered at the Hanford Site, and records of this type are the most complete of any in the world, from private companies or public agencies, for the early years of Site operations. The Hanford Site was unique for establishing a detailed, scientific, and multi-faceted environmental monitoring program

    Our investigation at 56 postoperative years focused on cognitive skills, with some emphasis on learning and memory; a clinical examination was also performed, and the anatomical extent of the resection was determined on 3-Tesla magnetic resonance imaging. Four age- and IQ-appropriate women were tested as healthy control subjects. The patient showed material-specific impairments in language and verbal memory compared with the control subjects and also compared with her own earlier performance, but her performance on other cognitive tasks did not differ from that of the control subjects. Thus, her specific deficits had worsened over time, and she was also impaired compared with healthy individuals of her age, but her deficits remained confined to the verbal sphere, consistent with her temporal lobe seizure focus and surgery.

    2014-01-01

    Purpose To review the progress made in understanding the genetic basis, molecular pathology, and treatment of retinoblastoma since the previous Jackson lecture on the topic was published 50 years ago. Design Perspective based on personal experience and the literature. Methods The literature regarding retinoblastoma was reviewed since 1963. Advances in understanding the biology and treatment of retinoblastoma provided context through the author’s clinical, pathological and research experiences. Results Retinoblastoma was first identified in the 1500s and defined as a unique clinicopathologic entity in 1809. Until the mid-1900s, knowledge advanced sporadically, with technological developments of ophthalmoscopy and light microscopy, and with the introduction of surgical enucleation, chemotherapy and radiation therapy. During the last 50 years, research and treatment have progressed at an unprecedented rate due to innovations in molecular biology and the development of targeted therapies. During this time period, the retinoblastoma gene was discovered; techniques for genetic testing for retinoblastoma were developed; and plaque brachytherapy, chemoreduction, intraarterial chemotherapy, and intraocular injections of chemotherapeutic agents were successfully introduced. Conclusions Nearly all patients with retinoblastoma in developed countries can now be cured of their primary cancer- a remarkable achievement for a childhood cancer that once was uniformly fatal. Much of this success is owed to deciphering the role of the Rb gene, and the benefits of targeted therapies, such as chemoreduction with consolidation as well as intra-arterial and intravitreal chemotherapies. Going forward, the main challenge will be ensuring that access to care is available for all children, particularly those in developing countries. PMID:25065496

    The paper presents a succinct history of Russian forests during the time period of 1960-2010 and reanalysis of their impacts on global carbon and nitrogen cycles. We present dynamics of land cover change (including major categories of forest land) and biometric characteristics of forests (species composition, age structure, growing stock volume etc.) based on reconciling all relevant information (data of forest and land inventories, official forest management statistics, multi-sensor remote sensing products, data of forest pathological monitoring etc.). Completeness and reliability of background information was different during the period of the study. Forest inventory data and official statistics were partially modified based on relevant auxiliary information and used for 1960-2000. The analysis for 2001-2010 was provided with a crucial use of multi-sensor remote sensing data. For this last period a hybrid forest mask was developed at resolution of 230m by integration of 8 remote sensing products and using geographical weighted regression and data of crowdsourcing. During the considered 50 years forested areas of Russia substantially increased by middle of 1990s and slightly declined (at about 5%) after. Indicators needed for assessment of carbon and nitrogen cycles of forest ecosystems were defined for the entire period (aggregated estimates by decades for 1960-2000 and yearly for 2001-2010) based on unified methodology with some peculiarities following from availability of information. Major results were obtained by landscape-ecosystem method that uses as comprehensive as possible empirical and semi-empirical information on ecosystems and landscapes in form of an Integrated Land Information System and complimentary combines pool- and flux-based methods. We discuss and quantify major drivers of forest cover change (socio-economic, environmental and climatic) including forest management (harvest, reforestation and afforestation), impacts of seasonal weather on

    A survey conducted in 1995 investigated long term declines reported in a population of box turtles Terrapene Carolina monitored each decade since 1945 in bottomland hardwood forest at the Patuxent Wildlife Research Center, Maryland. Methods duplicated past surveys in most respects, but were supplemented by radiotelemetry and a survey of dominant vegetation. Seventy different turtles were found on the 11.8 ha study area, a decline of >75% since peak populations were recorded in 1955. Searchers were less efficient in 1995 than in 1945-1975 for a variety of possible reasons. Among turtles recorded, approximately equal numbers persisted from each of the past five decades, with some individuals surviving >70 years. A sex ratio strongly favoring males was first recorded in 1975 and continued in 1995, but juveniles and subadults were found in greater proportion in 1995 than in any other survey. Six of nine radio-marked turtles left the bottomland study area and migrated to the adjoining bluffs to hibernate, suggesting more extensive movements and perhaps less stable home ranges than formerly thought. Age structure of trees indicated a gradual change to more shade-tolerant species. Examination of rates of change from survey data suggested that major losses probably resulted from changes in hydrology that exacerbated flooding in 1972, with recovery only beginning in 1995 and perhaps limited both by repeated flood events and successional changes in the forest. Slow recovery from losses may indicate that populations of the species would respond poorly to exploitation.

  5. Fifty years of research in Balkan endemic nephropathy: where are we now?

    Despite broad investigations into the possible role of genetic factors, environmental agents and immune mechanisms, the etiology of Balkan endemic nephropathy (BEN) is only partially understood. An increased incidence of upper urothelial cancer in patients with BEN and in populations from endemic settlements has been demonstrated. Genetic studies have landed support for genetic predisposition to BEN. The similarity of the morphological and clinical pattern of BEN and Chinese herbs nephropathy has raised the possibility of a common etiologic agent, aristolochic acid (AA), described in 1969 by Ivic and confirmed by a recent study of AA-DNA adducts. Ochratoxin A (OTA) is studied extensively as the etiologic agent of BEN. Weathering of low-rank coals nearby the endemic villages produces water-soluble polycyclic aromatic hydrocarbons and aromatic amines, similar to metabolic products of acetaminophen, which has a causal relationship with analgesic nephropathy. AA is confirmed as the etiologic agent of BEN; however, it may not be the sole risk factor. More research is needed on the patterns of BEN over time and between different endemic places. Therefore, it is important to test etiological hypotheses in different endemic foci, preferably as a multicentric research. An international approach to solving the etiology of BEN is needed in the coming years. The geographic correlation and presence of AA-DNA adducts in both BEN and associated urothelial cancer support the hypothesis that these diseases share a common etiology.

    2014-06-01

    Full Text Available This article builds a theoretical model for comparative analysis of media culture based on the notion of genre, and applies it to a comparative analysis of television as a cultural form in socialist and post-socialist Croatia. The paper explores how the shares and generic composition of program modes of information, entertainment and fiction change in time, and how the contribution of different genres to program flow and modes varies with the changes of political, economic and technological context. Longitudinal trends in television flows are comparatively evaluated in relation to trends in genre developments in Europe and their relationship to the changes in the cultural role of television. The results show a decrease in the information and an increase in the fiction mode between socialism and democracy, with some similarities of the Croatian and western television culture in relation to genre and mode composition and flow, albeit with a belated introduction of neo television genres. Notwithstanding the limited freedom of expression and ideological content, which necessarily influenced socialist media culture, television as a cultural form in Croatia developed in concert with the global program flows. The article is based on original content analysis of television schedules where the unit of analysis is a televisions program listing. The analogue television universe is represented by longitudinal data for 1959, 1969, 1979, 1989, 1999, and 2009. The stratified systematic sample (N=3934 for each chosen year consists of two constructed weeks from a universe of all listed programs broadcast on all free to air television channels with a national reach license.

  7. Ocean climate coupling in the tropical Pacific Ocean over the past fifty years: implications and feedbacks

    Full text: The tropical Pacific plays an important role in climate because of its significant air-sea exchanges of heat, freshwater, and carbon dioxide (C02), and because of its direct linkage to climate variability. There are two dominant modes of climate variability in the Tropics: the El Nino-Southern Oscillation (ENSO) phenomenon and the Pacific Decadal Oscillation (PDO). There has been strong evidence of ENSO and PDO impacts on tropical Pacific physics and biogeochemistry, including heat content, ocean circulation (McPhaden and Zhang 2002), and carbon fluxes (Feely ef al. 2006; Wang ef al. 2006). In this study, we apply a basin-scale ocean circulation-ecosystem-carbon model (Wang ef al. 2006) to study the responses of the tropical Pacific ecosystem, biogeochemistry and carbon cycle to climate forcing over the past 50 years. The model produces strong spatial and temporal variability in surface nutrient concentration, phytoplankton biomass, carbon uptake, and sea-to-air C02 flux, which are largely associated with the ENSO phenomenon. In particular, the size of the tropical Pacific C02 source is large during the ENSO cold phase but small during the ENSO warm phase. There are significant decadal variations in tropical Pacific carbon fluxes, reflecting physical and biogeochemical changes associated with the 1977 and 1997/98 PDO shifts. The 1977 regime shift caused 1 0 C warming in sea surface temperature and -50% reduction in surface iron concentration in the Niho3.4 area, leading to decreased biological activity. While there is a large decrease in phytoplankton growth and biomass, reduction in carbon uptake is smaller than expected, due to phytoplankton photoadaption, which increases the carbon to chlorophyll ratio in the upper euphotic zone and enhances sub-surface production. Photoadaption also results in clearer water near the surface, leading to less heating near the ocean surface and allowing more solar radiation to penetrate the subsurface. Our studies

  8. The big and little of fifty years of Moessbauer spectroscopy at Argonne.

    Energy Technology Data Exchange (ETDEWEB)

    Westfall, C.

    2005-09-20

    Using radioactive materials obtained by chance, a turntable employing gears from Heidelberg's mechanical toy shops, and other minimal equipment available in post World War II Germany, in 1959 Rudolf Moessbauer confirmed his suspicion that his graduate research had yielded ground-breaking results. He published his conclusion: an atomic nucleus in a crystal undergoes negligible recoil when it emits a low energy gamma ray and provides the entire energy to the gamma ray. In the beginning Moessbauer's news might have been dismissed. As Argonne nuclear physicist Gilbert Perlow noted: ''Everybody knew that nuclei were supposed to recoil when emitting gamma rays--people made those measurements every day''. If any such effect existed, why had no one noticed it before? The notion that some nuclei would not recoil was ''completely crazy'', in the words of the eminent University of Illinois condensed matter physicist Frederich Seitz. Intrigued, however, nuclear physicists as well as condensed matter (or solid state) physicists in various locations--but particularly at the Atomic Energy Research Establishment at Harwell in Britain and at Argonne and Los Alamos in the U.S.--found themselves pondering the Moessbauer spectra with its nuclear and solid state properties starting in late 1959. After an exciting year during which Moessbauer's ideas were confirmed and extended, the physics community concluded that Moessbauer was right. Moessbauer won the Nobel Prize for his work in 1961. In the 1960s and 1970s Argonne physicists produced an increasingly clear picture of the properties of matter using the spectroscopy ushered in by Moessbauer. The scale of this traditional Moessbauer spectroscopy, which required a radioactive source and other simple equipment, began quite modestly by Argonne standards. For example Argonne hosted traditional Moessbauer spectroscopy research using mostly existing equipment in the early days and

    Full Text Available Little is known about the state of experimentation in the field of medicine during the Medieval Islamic era. With few exceptions, most of the contemporary sources on history of medicine propagate the idea that the roots of experimental medicine in its modern form, including clinical trials and drug-potency studies, first started during the European Renaissance in the 16 th to the 18 th centuries. This study is part of an ongoing multidisciplinary primary-source investigation of the original Arabic works of 11 Islamic medical scholars who lived and practiced between the 9 th and the 13 th centuries. The study critically evaluated and documented their contributions to the development of the scientific method and experimental medicine during that medieval Islamic era in several areas including critical appraisal of previous knowledge, clinical observations and case reports, clinical therapeutic trials, drug potency trials, experimentation on animals, dissection and dissection experiments as well as postmortem examinations. In each of the above-mentioned areas, significant contributions were made during the Medieval Islamic era from as early as the ninth century AD.

    2003-12-01

    Full Text Available This paper will consider e-learning in terms of the underlying learning processes and interactions that are stimulated, supported or favoured by new media and the contexts or communities in which it is used. We will review and critique a selection of research and development from the past fifty years that has linked pedagogical and learning theory to the design of innovative e-learning systems and activities, and discuss their implications. It will include approaches that are, essentially, behaviourist (Skinner and Gagné, cognitivist (Pask, Piaget and Papert, situated (Lave, Wenger and Seely-Brown, socioconstructivist (Vygotsky, socio-cultural (Nardi and Engestrom and community-based (Wenger and Preece. Emerging from this review is the argument that effective elearning usually requires, or involves, high-quality educational discourse, that leads to, at the least, improved knowledge, and at the best, conceptual development and improved understanding. To achieve this I argue that we need to adopt a more holistic approach to design that synthesizes features of the included approaches, leading to a framework that emphasizes the relationships between cognitive changes, dialogue processes and the communities, or contexts for e-learning.

    2010-06-01

    Full Text Available Fifty years ago, the secrecy surrounding magnetically controlled thermonuclear fusion had been lifted allowing researchers to freely share technical results and discuss the challenges of harnessing fusion power. There were only four magnetic confinement fusion concepts pursued internationally: tokamak, stellarator, pinch, and mirror. Since the early 1970s, numerous fusion designs have been developed for the four original and three new approaches: spherical torus, field-reversed configuration, and spheromak. At present, the tokamak is regarded worldwide as the most viable candidate to demonstrate fusion energy generation. Numerous power plant studies (>50, extensive R&D programs, more than 100 operating experiments, and an impressive international collaboration led to the current wealth of fusion information and understanding. As a result, fusion promises to be a major part of the energy mix in the 21st century. The fusion roadmaps developed to date take different approaches, depending on the anticipated power plant concept and the degree of extrapolation beyond ITER. Several Demos with differing approaches will be built in the US, EU, Japan, China, Russia, Korea, India, and other countries to cover the wide range of near-term and advanced fusion systems.

  17. The cost of postgraduate medical education and continuing medical education: re-examining the status fifty years back.

    Science.gov (United States)

    Walsh, Kieran

    2015-03-01

    The subject of the cost and value of medical education is becoming increasingly important. However, this subject is not a new one. Fifty years ago, Mr. DH Patey, Dr. OF Davies, and Dr. John Ellis published a report on the state of postgraduate medical education in the UK. The report was wide-ranging, but it made a considerable mention of cost. In this short article, I have presented the documentary research that I conducted on their report. I have analyzed it from a positivist perspective and have concentrated on the subject of cost, as it appears in their report. The authors describe reforms within postgraduate medical education; however, they are clear from the start that the issue of cost can often be a barrier to such reforms. They state the need for basic facilities for medical education, but then outline the financial barriers to their development. The authors then discuss the costs of library services for education. They state that the "annual spending on libraries varies considerably throughout the country." The authors also describe the educational experiences of newly graduated doctors. According to them, the main problem is that these doctors do not have time to attend formal educational events, and that this will not be possible until there is "a more graduated approach to responsible clinical work," something which is not possible without financial investment. While concluding their report, the authors state that the limited money invested in postgraduate medical education and continuing medical education has been well spent, and that this has had a dual effect on improving medical education as well as the standards of medical care.

    The purposes of this study were to establish long-term outcome of the Spitzy shelf-operation and evaluate whether the procedure would delay osteoarthritis. During 1954-1976, 56 patients (70 hips) underwent Spitzy shelf operation at a mean age of 11.9 years (5 to 22). Indications included residual hip dysplasia or subluxation with Centre-Edge angle < 20°. We used survival analysis with conversion to total hip replacements as end-point. For patients without total hip replacement, information was provided from case records and radiographs. Avascular necrosis was assessed in pre-Spitzy radiographs, when available. Kaplan-Meier product-limit method was used to estimate survival function of the Spitzy shelf operation. Survival was assessed by Cox regression. Univariable Cox regression was performed separately for each variable. Potential predictors (p-value < 0.10) were entered into a multivariable regression model; p-value < 0.05 was considered significant. Mean survival of the shelf procedure was 39.9 years (21 to 53). Survival fell from 83 % 30 years post-operatively, to 22 % at 50 years. Fifty-three hips (76 %) had undergone total hip replacement at mean age of 49.4 years (33 to 64). Seventeen hips had not received total hip replacement, mean survival 47.9 years (39 to 53). The study showed that Spitzy shelf-operation had satisfactory long-term outcome with hip-survival in almost 90 % at patient age 40 years. The results indicate that Spitzy shelf-operation postpone total hip replacement. We consider Spitzy shelf-operation a good alternative in patients above 8 years. In younger children the procedure is not recommended due to increased frequency of graft resorption.

    Major changes happened in the last decade in the HIV/AIDS pandemic. The disease is no longer limited to young age. Due to the effectiveness of HAART (Highly Active Anti-Retroviral Therapy) as well as new diagnosis in older age groups, many patients in AIDS centers are above 50 years of age. To determine the prevalence, demographics and clinical characteristics of newly diagnosed HIV/AIDS patients older than 50 years compared to younger newly diagnosed patients. Retrospective single center analysis of the demographics and clinical characterizations of 62 newly diagnosed HIV/AIDS patients over 50 years of age. The average age at diagnosis of the whole cohort was 39+/-16 years. There was a gradual increase in the age at diagnosis over the years, as well as the percent of patients above the age of 50 diagnosed with the disease. In comparison to younger patients, in the older group there were more males compared to females and less patients who acquired the HIV/AIDS in unprotected homosexual sex. Furthermore, CD4 cells counts were lower and viral load leveLs were higher at diagnosis in the older group. Despite good adherence, patients above the age of 50 don't achieve adequate immunological response and many are left with significant immunodeficiency (CD4increasing number of patients over the age of 50 Living with HIV/AIDS.

Thirty-one such storms have affected the state in the past 56 years, either making landfall along the coast of southern New England, or passing close enough over the offshore waters to spread tropical storm or hurricane force conditions into the area. The intensities of these systems have ranged from weak, disorganized tropical storms to full fledged major hurricanes. The one feature common to almost all of the storms was a rapid acceleration toward Rhode Island, which greatly reduced the time to prepare and evacuate

    Over the past 50 years our laboratory has performed and published many studies in the fields of teratology, radiation biology and radiation embryology. The early work took place when I was a research employee at the University of Rochester Manhattan Project in 1944 and where I had my introduction to embryology and genetics. Over the years our lab has provided consultations dealing with the risks of various environmental toxicant exposures during pregnancy. With the advent of the Internet, consulting has become more rapid and efficient. In the past year our pregnancy Web site of the Health Physics Society received approximately 154,000 hits, of which over a thousand contacts were still quite anxious after reading the Web site answers and requested a personal consultation. From this extensive experience we have learned that many physicians and other counselors are not prepared to counsel patients concerning radiation risks. Approximately 8% of the patient contacts who have consulted a professional have been provided with inaccurate information that would have resulted in an unnecessary interruption of a wanted pregnancy. There are five areas of radiation embryology that are considered to be controversial. 1) Can the fetus be harmed by ionizing radiation if the fetus is not directly exposed? 2) Is the production of mental retardation from radiation during pregnancy a threshold phenomenon? 3) Does fractionation and protraction of radiation decrease the magnitude of the reproductive and developmental risks? 4) Is there a period during pregnancy when radiation will result in an increased mortality but not an increase in malformations? 5) How sensitive is the fetus to the oncogenic effects of radiation? We utilize the scientific information obtained from studies in these five areas to counsel patients concerning pregnancy radiation risks. The willingness and persistence of scientists to debate the controversial aspects of this research and apply the best available

    To provide an accurate estimate of violent war deaths. Analysis of survey data on mortality, adjusted for sampling bias and censoring, from nationally representative surveys designed to measure population health. Estimated deaths compared with estimates in database of passive reports. 2002-3 World health surveys, in which information was collected from one respondent per household about sibling deaths, including whether such deaths resulted from war injuries. Estimated deaths from war injuries in 13 countries over 50 years. From 1955 to 2002, data from the surveys indicated an estimated 5.4 million violent war deaths (95% confidence interval 3.0 to 8.7 million) in 13 countries, ranging from 7000 in the Republic of Congo [corrected] to 3.8 million in Vietnam. From 1995 to 2002 survey data indicate 36,000 war deaths annually (16,000 to 71,000) in the 13 countries studied. Data from passive surveillance, however, indicated a figure of only a third of this. On the basis of the relation between world health survey data and passive reports, we estimate 378,000 globalwar deaths annually from 1985-94, the last years for which complete passive surveillance data were available. The use of data on sibling history from peacetime population surveys can retrospectively estimate mortality from war. War causes more deaths than previously estimated, and there is no evidence to support a recent decline in war deaths.

    Secular trends have been found in the male-female ratio at birth (M/F: male births divided by total births) in various countries and this ratio is anticipated to approximate 0.515. Annual national data for male and female live births in Cuba with contingency tables were obtained from the World Health Organisation and analysed. There were 3 736 718 male and 3 534 270 female births (1960-96). Births declined steadily over the entire period. The male-female ratio at birth remained relatively stable over the period 1960-1985 with significant sharp dips for the years 1966, 1980 and 1985. There was a sharp rise in M/F from 1966 to 1969, another rise after 1985, a steep drop to 1989, and then a sharp rise once more after 1993 (all p influencing M/F.

    2006-02-01

    In 1905 the first German association of Social Medicine was founded. Out of its now 100 years of history two aspects which were of peculiar importance for its development are studied here by the method of historic analysis of the sources and the examination of secondary literature: the noteworthiness of this foundation is characterized by the fact that the society was based from its beginnings on multidisciplinarity and the appliance of different scientific methods. It is showed which fascination had exclusively biological and genetic explanations for the genesis of diseases and human attitude characteristics. In transformation to practical action these ideas led to the extermination of disease causing genetic attributes and often their bearers as well. This aim was followed up even when the genetic causation of specified attitudes was not clearly proved. These biological interpretations of disease phenomenons neglected social causes for the process of the appearance of certain diseases and the emergence of health. They were responsible for medical interventions into the physical integrity of hundreds of thousands of human beings under the political terms and conditions of National Socialism.

    Full Text Available Objective. The European Academy of Teachers in General Practice / Family Medicine (EURACT has developed an educational agenda, the key document for teaching family medicine in Europe. The aim of our study was to find out how final year medical students at the beginning of their family medicine clerkship understand the discipline of family medicine. Methods. The attitudes toward family medicine were paraphrased and developed into a 164-item questionnaire, which was administered to 335 final-year medical students at the beginning of their clerkship. Using combinatorial optimization with genetic algorithms we selected 30 items which yielded the highest Cronbach alpha reliability coefficient. Finally, we performed a factor analysis to find which dimensions of family medicine were recognised by the students and compared them with the domains defined in the EURACT definition. Results. The 30-item questionnaire had a Cronbach alpha reliability coefficient of 0.919. The differences between male and female students were not very significant (p=0.061. With the factor analysis we recognised seven factors, belonging to three out of six domains of the EURACT educational agenda: primary care management, personcenteredness and comprehensive approach. Conclusion. Final-year medical students at the beginning of their family medicine clerkship understand some of the dimensions of family medicine rather well, but they are not aware of some important competences of family doctors. There is a necessity to teach students about specific problem solving skills and the importance of balance between the health needs of an individual patient and the community.

    2012-01-01

    This review will mainly focus the last 10 years of the society's history because several important changes occurred during this relatively short period. The most important was the creation of the first clinical sports medicine department in Luxembourg in 2004. This modern new infrastructure was made possible by the recruitment of 2 highly competent sports physicians, the excellent collaboration of the governing board of the Centre Hospitalier de Luxembourg (CHL) and the support of the sports minister. In 2008 the new department received the label "Medical Olympic Centre of Luxembourg". One year later a Research Lab of Sports Medicine (CRP-Santé) completed the new concept. Thus within 4 years the structure of Luxembourgish sports medicine was completely rearranged and includes today orthopaedic surgery and traumatology, functional rehabilitation, sports cardiology, exercise physiology, physiotherapy and specific sports medicine research. An important new challenge of the SLMS will be to integrate the external sports physicians into this new infrastructure. Another ongoing mission of the SLMS will be the education and training of new young sports medicine specialists. Here the new department could play an outstanding role and the SLMS is in close negotiations with the University of Luxembourg, in charge of academic education in Luxembourg. A recruitment of new young sports physicians is necessary to perpetuate the routine sports medicine exams in the 15 regional centres in Luxembourg, where such an exam is mandatory in order to get an official sports licence. Since 2010 an ECG exam has been added for all new licence candidates, according to the recent recommendations of the scientific societies. New young sports physicians will also be needed to assure the medical attendance of the different national teams of Luxembourg. Until 1985 these activities were confined only to the Olympic teams every 4 years, but since the implementation of the Games of the Small European

    Radiation dose calculation using models of the human anatomy has been a subject of great interest to radiation protection, medical imaging, and radiotherapy. However, early pioneers of this field did not foresee the exponential growth of research activity as observed today. This review article walks the reader through the history of the research and development in this field of study which started some 50 years ago. This review identifies a clear progression of computational phantom complexity which can be denoted by three distinct generations. The first generation of stylized phantoms, representing a grouping of less than dozen models, was initially developed in the 1960s at Oak Ridge National Laboratory to calculate internal doses from nuclear medicine procedures. Despite their anatomical simplicity, these computational phantoms were the best tools available at the time for internal/external dosimetry, image evaluation, and treatment dose evaluations. A second generation of a large number of voxelized phantoms arose rapidly in the late 1980s as a result of the increased availability of tomographic medical imaging and computers. Surprisingly, the last decade saw the emergence of the third generation of phantoms which are based on advanced geometries called boundary representation (BREP) in the form of Non-Uniform Rational B-Splines (NURBS) or polygonal meshes. This new class of phantoms now consists of over 287 models including those used for non-ionizing radiation applications. This review article aims to provide the reader with a general understanding of how the field of computational phantoms came about and the technical challenges it faced at different times. This goal is achieved by defining basic geometry modeling techniques and by analyzing selected phantoms in terms of geometrical features and dosimetric problems to be solved. The rich historical information is summarized in four tables that are aided by highlights in the text on how some of the most

    Full Text Available The Submarine arm of the Indian Navy is in its Golden Jubilee year, celebrating 50 glorious years of service to the Nation. From a small force of Foxtrot class, it leapfrogged into high technology boats in just 25 years of its coming into being. Forays into operating a nuclear Submarine have brought the Navy into the fold of of modern Submarine powers. In this journey, it has also graduated from acquiring Submarines from foreign nations to the present day indigenous construction of both conventional and nuclear boats. Submarine Medicine has been an inseparable part of strengthening the Naval capability throughout this endeavor.

    The Lower Colorado River Delta in the U.S. and Mexico is an internationally important aquatic biome, supporting fresh water and estuarine wetlands and a riparian corridor rich in avian and other wildlife. These rich ecosystems could be severely harmed by invasive species interacting with projected climate change and land use practices over the next 50 years. It is critical to measure land cover and monitor ecosystem and land use changes because these ecosystems are supported by fresh and brackish water flows originating from flood control releases and agricultural return flows in the U.S. and Mexico. Most climate models project a drying trend in the Colorado River watershed due to global warming, decreasing the frequency of flood releases to the Delta. Total basin water storage in the reservoir system is expected to be reduced by 32-40 percent, and flow volume is expected to meet demands in only 59-75 percent of years in 50 years. The frequency of spills (years in which water is released from the reservoirs to the Delta) will decrease under a global warming scenario. However, the Pacific Decadal Oscillation and ENSO events will continue to introduce variability into river flows, and there will still be years in which water is spilled to the Delta. Agricultural return flows will decrease as more water is diverted from agriculture to metropolitan use in both countries. The salinity of the ground water in Mexico, which currently supports cottonwood and willow trees in the riparian corridor, is increasing at a rate of about 20 ppm per year, and in 50 years it might be too saline for cottonwoods and willows. The riparian zone may become dominated by saltcedar and other salt-tolerant shrubs, degrading the habitat for birds and other wildlife. As flows to the Delta diminish, monitoring and active restoration projects to maintain trees and wetlands will be needed to preserve habitat value.

    Full Text Available Aim: The purpose of this study was to determine the incidence of anterior cruciate ligament (ACL lesions and osteochondral lesions according to type and localization of the meniscal tear and age, gender in patients who have been arthroscopicaly treated, besides, to make the coexisting lesions more predictable in these patients. Methods: We retrospectively investigated 352 patients under 50 years of age who underwent surgery for a meniscal tear between 2008 and 2012. We scanned the surgical operation notes, preoperative questionnaires and the magnetic resonance imaging findings. We recorded patients who had ACL lesions, such as elongation, partial rupture and total rupture. Osteochondral lesions were classified according to the Outerbridge classification from grade 1 to grade 4. Results: Chondral lesions were present in 77.4% of patients with degenerative meniscal tears and in 63% of patients with radial meniscal tears. One the other hand, osteochondral lesions were observed in only 33.9% of patients with other types of meniscal tears. 46.6% of ACL lesions accompanied by meniscal tears with longitudinal pattern, such as longitudinal tears, bucket handle tears and root tears. For the other types of meniscal tears, this percentage was 20.7. When we excluded degenerative type meniscal tears, the mean age of the patients with radial tears was 40.86±9.03 years and the mean age of the patients with other types of tear was 35.44±9.44 years. The difference was statistically significant. Conclusion: We found close relationship between osteoarthritic chondral lesions and radial tears in the root of the posterior horn of the medial meniscus. On the other side, longitudinal tears were related with ACL lesions. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 177-80

    Sodium and chloride have increased in the last 50 years in this river ecosystem. - Ecological studies have demonstrated the adverse effects of road-salt, primarily NaCl, on water quality, flora, and fauna. In this study, we quantified changes in ionic composition and solute flux of water draining the Mohawk River Basin (9103 km 2 ) in New York State, from 1952 to 1998. Using various statistical, graphical, and modeling techniques, we showed that concentrations of Na + and Cl - have increased by 130 and 243%, respectively, while other constituents have decreased or remained constant. The use of de-icing salt on roads within the watershed, which we estimate at 39 kg km -2 day -1 , appears to be the primary mechanism responsible for reported increases, accounting for the increase in NaCl export from 16 to 46 kg km -2 day -1 over the 47-year period. Moreover, despite population decline within this rural upstate watershed, increased environmental stewardship, and The Clean Water Act, concentrations of Na + and Cl - still increased during the 1990s

    The 1.3 m Robotically Controlled Telescope (RCT) on Kitt Peak has a rich history, including its role as a prototype for remotely controlled telescopes during the 1960s. As such, the RCT could be considered one of the first - Telescopes from Afar. The telescope, originally called the Remotely Controlled Telescope, has been renamed the Robotically Controlled Telescope to reflect the change in operational control and mode of use. The RCT was a conceptual precursor of today's robotic telescopes, but the actual operation of a remotely controlled telescope was technologically premature for its time, and was subsequently manually operated primarily to conduct optical and infrared observations as well being used as a test bed for new spectroscopic and photometric instruments. In 1995 budget constraints forced the closing of the telescope as part of the Kitt Peak National Observatory (KPNO), following nearly 30 years of distinguished service to KPNO. A request for proposals to operate this telescope was issued to the science community. The RCT consortium, lead by Western Kentucky University, was the successful proposer for operation of the telescope. After several difficult years of retrofitting, refurbishing, and automating the telecope and observatory dome, the telescope has returned to routine science operations in November 2009. The RCT has operated smoothly since that time, with no major interruptions. Observations of objects of interest to the consortium partners (including: comets & asteroids, variable & binary stars, exoplanets, supernovae, quasars & blazars) are being routinely obtained and evaluated. One of the distinguishing features of the RCT is that it is an autonomous observatory designed to handle diverse optical imaging and photometry programs. These include being able to automatically deal with a wide range of observing parameters such as -integration time, sky conditions, repetitions, return visits, filters, air mass, non-sidereal objects, transients etc

    Past fire recurrence impacts the vegetation structure, and it is consequently hypothesized to alter its future fire behaviour. We examined the fire behaviour in shrubland-forest mosaics of southeastern France, which were organized along a range of fire frequency (0 to 3-4 fires along the past 50 years) and had different time intervals between fires. The mosaic was dominated by Quercus suber L. and Erica-Cistus shrubland communities. We described the vegetation structure through measurements of tree height, base of tree crown or shrub layer, mean diameter, cover, plant water content and bulk density. We used the physical model Firetec to simulate the fire behaviour. Fire intensity, fire spread, plant water content and biomass loss varied significantly according to fire recurrence and vegetation structure, mainly linked to the time since the last fire, then the number of fires. These results confirm that past fire recurrence affects future fire behaviour, with multi-layered vegetation (particularly high shrublands) producing more intense fires, contrary to submature Quercus woodlands that have not burnt since 1959 and that are unlikely to reburn. Further simulations, with more vegetation scenes according to shrub and canopy covers, will complete this study in order to discuss the fire propagation risk in heterogeneous vegetation, particularly in the Mediterranean area, with a view to a local management of these ecosystems.

    Full Text Available The 1968 American Heart Association announced a dietary recommendation that all individuals consume less than 300 mg of dietary cholesterol per day and no more than three whole eggs per week. This recommendation has not only significantly impacted the dietary patterns of the population, but also resulted in the public limiting a highly nutritious and affordable source of high quality nutrients, including choline which was limited in the diets of most individuals. The egg industry addressed the egg issue with research documenting the minimal effect of egg intake on plasma lipoprotein levels, as well as research verifying the importance of egg nutrients in a variety of issues related to health promotion. In 2015 dietary cholesterol and egg restrictions have been dropped by most health promotion agencies worldwide and recommended to be dropped from the 2015 Dietary Guidelines for Americans.

    2015-05-18

    Half a century after Schill and Lüttringhaus carried out the first directed synthesis of a [2]catenane, a plethora of strategies now exist for the construction of molecular Hopf links (singly interlocked rings), the simplest type of catenane. The precision and effectiveness with which suitable templates and/or noncovalent interactions can arrange building blocks has also enabled the synthesis of intricate and often beautiful higher order interlocked systems, including Solomon links, Borromean rings, and a Star of David catenane. This Review outlines the diverse strategies that exist for synthesizing catenanes in the 21st century and examines their emerging applications and the challenges that still exist for the synthesis of more complex topologies. © 2015 WILEY-VCH Verlag GmbH & Co.

    Full Text Available Whatever part of the World you come from, when you come to Rijeka you came to the heart of Europe. Rijeka is waiting for you with the scent of its sea and the hospitality of its people. Rijeka is a town of unusual, turbulent and intersected history. At the end of the IX Century the area of Rijeka was one of the most powerful industrial zones in Europe. Prof. Eugen Cerkovnikov, Ph. D., a much-respected chemist, first Head of the Department for Chemistry and Biochemistry on the then newly established Medical School in Rijeka, launched the initiative to form a branch-office of the Croatian Chemist Society in Rijeka. On 18 January, 1958 in the Big Classroom of the Medical School in Rijeka the Founding Assembly was held, and many respected scientists of that period were present.In 1960, the Rijeka branch-office of the Croatian Chemist Society merged with the Society of Chemists and Technologists and in 1973 the Biochemists section joined. In the five decades of its existence, the love towards chemistry, biochemistry, molecular biology, technology and chemical engineering, the love towards the basis of natural sciences and the wish to educate new, progressive generations formed the mission of the Society. The Society does not want to be closed in a guild organisation; its aim is to open its doors towards all those striving to progress.Former presidents of the Society were: Eugen Cerkovnikov (1958-1974, Marijan Kolombo (1974-1980, Josip Šilipeter (1980-1984, Marinko Oršia (1984-1996 i Nikola Bla?evia (1996-; and each one of them marked his era. Transitional circumstances have shut down forever many, until recently, extremely powerful industries in Rijeka. Today, Rijeka is searching for new paths, and we believe that our Society will continue to work on and give its contribution to this search.

  14. Fifty years chlorpromazine: a historical perspective.

    Ban, Thomas A

    2007-08-01

    Chlorpromazine was synthesized in December 1951 in the laboratories of Rhône-Poiulenc, and became available on prescription in France in November 1952. Its effectiveness was reflected in the transformation of disturbed wards; its commercial success stimulated the development of other psychotropic drugs. Recognition of chemical mediation at the site of the synapse, followed by the introduction of the spectrophotofluorimeter first, and receptor assays subsequently, led to the demonstration that chlorpromazine blocks dopamine receptors. Treatment with chlorpromazine focused attention on the heterogeneity of schizophrenia in terms of responsiveness to treatment. By the mid-1980s there was sufficient evidence to believe that resolving this heterogeneity is a prerequisite for developing more effective treatments. Chlorpromazine was instrumental in the development of neuropsychopharmacology, a new discipline dedicated to the study of mental pathology with the employment of centrally acting drugs.

    To study the most important metrics of publication in the field of reproductive medicine over the decade 2003-2012 to aid in discerning the clinical, social, and epidemiologic implications of this relatively new but rapidly emerging area in medical sciences. Bibliometric analysis of most-cited publications from Web of Science databases. Not applicable. None. None. Most productive and frequently cited investigators, institutions, and countries and specific areas of research, scientific collaborations, and comparison of the growth of reproductive medicine research compared with other areas of medical investigation such as obstetrics and gynecology and related science categories. We found that 90 investigators with more than 1,000 citations had jointly published 4,010 articles. A continued rise in the impact factor of reproductive medicine journals was seen. The number of publications in reproductive medicine grew more rapidly compared with other science categories. Presently 22% of highly cited articles in reproductive medicine research are published in journals belonging to science categories outside reproductive medicine. The most-cited study groups are situated in the Netherlands, Belgium, Spain, the United States, and the United Kingdom, and collaborative studies have been increasing. Reproductive medicine research and subsequent clinical development have attained scientific growth and maturity. High-quality research is increasingly being published in high-impact journals. The increase in (inter)national collaborations seems to be key to the field's success. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

    This paper is the first in a series of invited perspectives by pioneers of nuclear medicine imaging and physics. A medical physicist and a nuclear medicine physician each take a backward and a forward look at the contributions of physics to nuclear medicine. Here, we provide a forward look from the medical physicist’s perspective. The author examines a number of developments in nuclear medicine and discusses the ways in which physics has contributed to these. Future developments are postulated in the context of an increasingly personalised approach to medical diagnostics and therapies. A skill set for the next generation of medical physicists in nuclear medicine is proposed in the context of the increasing complexity of ‘Molecular Imaging’ in the next three decades. The author sees a shift away from ‘traditional’ roles in instrumentation QA to more innovative approaches in understanding radiobiology and human disease.

  20. The practice of medicine in England about the year 1000.

    Meaney, A

    2000-08-01

    The paper begins with the medical practitioners of late Anglo-Saxon England, were apparently both physicians and surgeons, describing the kinds of ailments they are evidenced as treating. The majority were monastic; whether there were also lay medics is uncertain. Most Anglo-Saxon ecclesiastical foundations appear to have had an infirmary, where sick monks or nuns, or those who were about to die, were looked after. Some infirmaries may have tended lay people, but there do not appear to have been any hospitals in the later medieval sense. The rest of the paper looks at the contents of one manuscript written about the year 1000: London, British Library MS. Harley 585, which contains texts of three compilations in old English: the Herbarium and the Medicina de Quadrupedibus, both translated from Latin, and the Lacnunga, which is a collection of remedies from diverse sources, some translated from Latin, some of native origin, some wholly rational, some containing Christian or folkloric incantations and rituals, and including four metrical charms. Because of its lack of selectivity and orgarization, it gives an invaluable insight into the condition of, and the attitude to, Anglo-Saxon medicine about the end of the first millennium.

    Nuclear medicine has an important role in the care of newborns and children less than 1 y old. Patients in this age group present with a spectrum of diseases different from those of older children or adults. These patients can benefit from the full range of nuclear medicine studies. In these young children, nuclear medicine studies are more likely to be used to evaluate a wide range of congenital conditions but also can be helpful for evaluating acquired conditions such as infection, cancer, and trauma. This review first will cover the general aspects of nuclear medicine practice with these patients, including the special considerations that can help achieve successful diagnostic imaging. These topics will include clinical indications, imaging technology, instrumentation, software, positioning and immobilization, sedation, local and general anesthesia, radiopharmaceutical doses, radiation risk, and dose reduction. The review then will discuss the specific nuclear medicine studies that typically are obtained in patients in this age group. With extra care and attention to the special needs of this population, nuclear medicine departments can successfully study patients less than 1 y old.

  2. Third- and Fourth-Year Medical Students' Changing Views of Family Medicine.

    2016-01-01

    The effect of third-year family medicine clerkships on shaping contemporary US students' knowledge and attitudes toward family medicine is not well understood. The objectives of this study were to assess third-year medical students' attitudes toward family medicine before and after a family medicine clerkship, to assess students' interest in a family medicine career before and after the clerkship, and to compare these findings to the same students' attitudes toward family medicine in the fourth year. An anonymous questionnaire assessing attitudes toward family medicine was offered to 150 medical students in the class of 2011 at a geographically dispersed, community-based US medical school. Students were offered the questionnaire during their third year, on the first and last days of the required 8-week family medicine clerkship, and midway through the fourth year. At least 92 students completed participation at each time point (response rate 61%). Twenty-seven percent of students initially unlikely to choose family medicine as a career became interested after the clerkship. Ninety percent of those interested in family medicine maintained their interest. Attitudes toward lifestyle and compensation, family medicine's role in research, and family physician expertise significantly improved after the clerkship. However, gains in some of these areas regressed in the fourth year. The clerkship improves students' attitudes toward, and interest in, family medicine. However, students' favorable attitudes deteriorate when they are no longer exposed to family medicine instruction. Educational practices focused on fourth-year students may be needed to support and maintain student interest in family medicine.

  3. Regenerative medicine: looking backward 10 years further on.

    The last decade has seen considerable changes in the Regenerative Medicine industry, but unfortunately the hope for numerous treatments that 'replace or regenerate human cells, tissues or organs to restore or establish normal function' has not yet emerged. In contrast to this, there have been major advances in the field of cellular immunotherapy though some do not consider these to be Regenerative Medicines. Regulatory changes have in some cases improved the route to a marketing license but they have not been matched by clarification of the complex, national reimbursement processes for cell-based treatments and this has adversely affected a number of leading Regenerative Medicine Companies. The review considers the direction that the industry may go in the future in relation to scientific, manufacturing and clinical strategies which may improve the rate of success of new therapies..

    Previous studies reported variable outcome and failure rates after mega-prosthetic reconstructions in the lower extremities. The purpose of this study was to make a long-term single-center evaluation of patients treated with limb-sparing surgery and reconstruction with mega-prostheses in the lower extremities. We identified 50 patients (osteosarcoma (n = 30), chondrosarcoma (n = 9), osteoclastoma (n = 6), Ewing sarcoma (n = 4), angiosarcoma (n = 1)), who underwent limb-sparing reconstruction of the lower extremities (proximal femur (n = 9), distal femur (n = 29), proximal tibia (n = 9), and the entire femur (n = 3)) between 1985 and 2005. Surviving patients not lost to follow-up were evaluated using the MSTS score. Causes of failure were classified according to the Henderson classification. Kaplan-Meier survival analysis was used for evaluation of patient, prosthesis, and limb survival. Twenty-eight patients were alive at follow-up. Fifty-four percent had revision surgery (n = 27). The ten year patient survival was 60% (95%CI 46-74%); the ten year implant survival was 24% (95%CI 9-41%), and the ten year limb survival rate was 83% (95%CI 65-96%). Type 1 failure occurred in 9%, type 2 in 16%, type 3 in 28%, type 4 in 18%, and type 5 in 3%. Mean MSTS score was 21 (range, 6-30), representing a median score of 71%. Our long-term results with mega-prostheses justify the use of limb-salvage surgery and prosthetic reconstruction. Our results are fully comparable with other findings, with regard to limb and prosthesis survival, but also with regard to functional outcome.

    The need for physicians and technical consultants specialized in transfusion medicine is urgent in China, as there are 20 000 hospitals and 500 blood centers in need of staff with this expertise. The progress made in transfusion medicine as a specialty has been relatively slow in China. Current Chinese medical education and service systems have not developed transfusion medicine as a stand-alone medical specialty. Most physicians receive only minimal training in transfusion medicine in medical school. This training is usually integrated into surgical training and addresses the most common technologies. In 2008, a 5-year bachelor's diploma program in transfusion medicine was established as an undergraduate specialty in Southern Medical University, Guangzhou, China. This article intends to summarize the 8 years of experience educating undergraduates in the specialty of transfusion medicine. Copyright © 2017. Published by Elsevier Inc.

    Almost nothing was known about the effects of spaceflight on human physiology when, in May of 1961, President John F. Kennedy committed the United States to land a man on the Moon and return him safely to Earth within the decade. There were more questions than answers regarding the effects of acceleration, vibration, cabin pressure, CO2 concentration, and microgravity. There were known external threats to life, such as solar and ultraviolet radiation, meteorites, and extreme temperatures as well as issues for which the physicians and scientists could not even formulate the questions. And there was no time for controlled experiments with the required numbers of animal or human subjects. Of necessity, risks were evaluated and mitigated or accepted based on minimal data. This article summarizes presentations originally given as a panel at the 79th Annual Scientific Meeting of the Aerospace Medical Association in Boston in 2008. In it, five pioneers in space medicine at NASA looked back on the development of their field. The authors related personal anecdotes, discussed the roles of various people and presented examples of contributions to emerging U.S. initiatives for human spaceflight. Topics included the development of quarantine facilities for returning Apollo astronauts, the struggles between operational medicine and research personnel, and observations from the first U.S. medical officer to experience weightlessness on orbit. Brief biographies of the authors are appended to document their participation in these historic events.

    Full text: The intention of this article is to describe the contributions of the many nuclear medicine physicists who in a large or small way have added to the ongoing development of nuclear medicine in Australia from the first years of the discipline in the late 1960s to the present time. Unlike our colleagues in radiation oncology physics, the nuclear medicine physicist fraternity has always been a very small group which unfortunately has not expanded greatly over the 30 years and beyond. This is emphasized in the survey by W.H.Round 1 which showed the bias towards older physicists being involved in the discipline. Because of the small numbers of nuclear medicine physicists in the public hospital system, mostly one or two per teaching hospital, most physicists are heavily involved in clinical duties to keep up the high standard of equipment and software performance required. Many nuclear medicine physicists also have the dual role of hospital radiation safety officers which is becoming more demanding as radiation legislation increases. For this reason much of the pure research has been confined to the hospitals with larger numbers of physicists. However a high proportion of nuclear medicine physicists across the country have contributed greatly to clinical research and development as part of their job. Unfortunately these cannot all be recognised in this article. Young physicists may not realise how much 'in house' research and development was carried out by physicists in the early years of nuclear medicine when equipment companies did not provide the software which is now available to purchase. Many of these innovative techniques and software, described in this article, are still in use today. Some of the 'big events' in the history of nuclear medicine in Australia in which physicists have played a leading role will also be highlighted. This will serve to emphasize how physicists have worked closely with clinicians and technologists in the ongoing development of

    older people experience more chronic medical conditions than younger people, take more prescription medicines and are more likely to suffer from cognitive or memory problems. Older people are more susceptible to the adverse effects of medicines, which may reduce their quality of life or lead to hospitalisation or death. this study aims to identify medicine-taking practices amongst community-dwelling people aged > or =75 years in New Zealand. this study was carried out in an urban setting in Dunedin (population 120,000), New Zealand. Interviews of a random sample of people from the electoral roll using a structured questionnaire were conducted. Subjects were community-dwelling people aged > or =75 years taking one or more prescription medicines. From a random sample of 810 people extracted from the electoral roll intended to recruit 300 participants, 524 people met the study criteria and were invited to participate. People living in a rest home or hospital, not contactable by telephone, or now deceased, were excluded. Responses were analysed, medicines categorised by the Anatomical Therapeutic Chemical classification and adherence classed as high, medium and low using a modified four-item Morisky Medication Adherence Scale. Univariate and multivariate linear and logistic regression was applied to combinations of variables. in total, 316 interviews were undertaken; a 61% response rate. Participants were 75-79 (35%), 80-84 (40%) and >85 years (25%); New Zealand European/European (84%), 'New Zealanders' (14%) or Maori (2%); and 141 (45%) lived alone. Almost half (49%) regularly saw a specialist and a third (34%) had been admitted to hospital in the past 12 months. Participants used a median of seven prescription medicines (range 1-19) and one non-prescription medicine (0-14). The majority (58%) believed medicines are effective and had systems/routines (92%) for remembering to take them. Doses tended to be missed following a change in routine, e.g. holiday. Men were

    The aim of this study was to review the pattern of radionuclide treatments used in a multidisciplinary neuroendocrine tumour clinic over an 8-year period 1998- 2006. The notes of all 782 patients attending the Royal Free Hospital Neuroendocrine Tumour Clinic from 1998-2006 were examined. If they had received radionuclide therapy, a note was made of the therapy given. It was found that there were six separate forms of radionuclide therapy administered. This included high activity In-111 octreotide therapy were 5-7 GBq of In-111 octreotide was given 3 monthly with between 1 and 8 times. The second form of radionuclide therapy was Y-90 lanreotide. This was given in a standard activity of 1.2GBq and given either intravenously or infused into the hepatic artery normally 3 doses were given 6-8 weeks apart and the whole procedure could be repeated if required. The third radiopeptide therapy was Y-90 octreotate. This was given in 2 activity levels 1.2GBq for intra-arterial therapies and 3GBq for intravenous therapies; these were given 8-10 weeks with a maximum of 3 cycles. When given intravenously the patient had co-administration of renal protecting amino acids. The forth form of therapy was I-131 mIBG given in two dosage regimes; a low activity regime of 3 treatments of 3Gbq 12 weeks apart and a higher activity regime of 6GBq of I-131 mIBG 12 weeks apart. These treatments could be repeated up to 3 times. The fifth treatment was intra-arterial I-131 Lipiodol for receptor negative disease and Sm-153 EDTMP for bone pain. The results of the survey are given. In total, 201 patients (26%) of patients attending a neuroendocrine tumour clinic received radionuclide therapy showing this is a major method by which these patients are treated

    There is a hierarchical organisation of knowledge in the use of medicinal plants in communities. Medicinal use knowledge starts in the home and is passed on to family members. Next in the hierarchy are neighbours, village elders and finally, traditional healers being the most knowledgeable. For primary health care this hierarchy is actively followed in seeking remedies for ailments. This study was a survey of medicinal plant knowledge from family members of 1(st) year medical students registered at Walter Sisulu University. A total of 206 first year medical students participated in this study in 2010 and 2011. Results revealed 47 species used as home remedies, 32% of which are food plants. Leaves and roots were reported as most commonly used. The top five ailments managed at home were gastrointestinal problems (25 plants), wounds (19 plants), respiratory tract problems (19 plants), infections, including sexually transmitted diseases (19 plants) and pain including headaches (19 plants). Chronic diseases such as hypertension, diabetes, cancer and reproductive ailments also formed a large group of diseases self-managed at home (29 plants). Family members hold knowledge of medicinal plant use. From this study, first year medical students were made aware of the relationship between common ailments and associated home remedies. This study forms a basis for further study of medicinal plants to validate their use as medicinal remedies.

  17. Sustainable Foods and Medicines Support Vitality, Sex and Longevity for a 100-Year Starship Expedition

    Science.gov (United States)

    Edwards, M. R.

    Extended space flight requires foods and medicines that sustain crew health and vitality. The health and therapeutic needs for the entire crew and their children for a 100-year space flight must be sustainable. The starship cannot depend on resupply or carry a large cargo of pharmaceuticals. Everything in the starship must be completely recyclable and reconstructable, including food, feed, textiles, building materials, pharmaceuticals, vaccines, and medicines. Smart microfarms will produce functional foods with superior nutrition and sensory attributes. These foods provide high-quality protein and nutralence (nutrient density), that avoids obesity, diabetes, and other Western diseases. The combination of functional foods, lifestyle actions, and medicines will support crew immunity, energy, vitality, sustained strong health, and longevity. Smart microfarms enable the production of fresh medicines in hours or days, eliminating the need for a large dispensary, which eliminates concern over drug shelf life. Smart microfarms are adaptable to the extreme growing area, resource, and environmental constraints associated with an extended starship expedition.

    2015-01-01

    The faculty at member schools and colleges of the Association of American Veterinary Medical Colleges (AAVMC) are critical for continued progress in veterinary medicine. The success of those faculty members over the past 50 years has positioned veterinary medicine to engage an ever-widening array of opportunities, responsibilities, and societal needs. Yet the array of skills and accomplishments of faculty in academic veterinary medicine are not always visible to the public, or even within our profession. The quality and the wide range of their scholarship are reflected, in part, through the according of national and international awards and honors from organizations relevant to their particular areas of expertise. The goal of this study was to illustrate the breadth of expertise and the quality of the faculty at 34 schools/colleges of veterinary medicine by examining the diversity of organizations that have recognized excellence in faculty achievements through a variety of awards.

    The aim of this study was to assess the value of personal dosimetry for nuclear medicine personnel in our department in a ten-year period. We have analyzed personal doses for 80 employees in nuclear medicine in a ten year period that we divided into two five year periods (from 2000 to 2004 and from 2005 to 2009). The personnel was dived into 8 groups according to their working assignments due to different radiation exposure from various radioisotopes in different wards in nuclear medicine: nuclear medicine specialists, technologists in scintigraphy ward, personnel of physics ward, ward for radiochemistry and radioimmunology, clinical ward and ultrasound ward, cleaning personnel, administrative personnel. We have compared average dose per person in particular ward in two five year periods. All doses for all personnel were in the permissible limits prescribed by the authorities. Higher average dose per person in a first five year period was detected in two wards, scintigraphy ward and ward for radiochemistry and radioimmunology due to the nature of their working assignments (preparation and application of radiopharmaceuticals, contact with patients who have received radiopharmaceutical). The decrease in the average dose per person was noticed in a second five-year period, especially in the wards with personnel that had no prior education in ionizing radiation protection. The decrease of dose was from 7.5 % to 84.2 %. We think that the decrease of average dose per person in a second five-year period was not only the result of the increased personal protection measures but also the result of continuing education of nuclear medicine personnel that is obligatory by the Law for ionizing radiation protection from year 1999, and the results from a ten-year period show its positive effect on radiation protection.

    The role of the internal medicine chief resident includes various administrative, academic, social, and educational responsibilities, fulfillment of which prepares residents for further leadership tasks. However, the chief resident position has historically only been held by a few residents. As fourth-year chief residents are becoming less common, we considered a new model for rotating third-year residents as the chief resident. Online surveys were given to all 29 internal medicine residents in a single university-based program after implementation of a leadership curriculum and specific job description for the third-year chief resident. Chief residents evaluated themselves on various aspects of leadership. Participation was voluntary. Descriptive statistics were generated using SPSS version 21. Thirteen junior (first- or second-year) resident responses reported that the chief residents elicited input from others (mean rating 6.8), were committed to the team (6.8), resolved conflict (6.7), ensured efficiency, organization and productivity of the team (6.7), participated actively (7.0), and managed resources (6.6). Responses from senior residents averaged 1 point higher for each item; this pattern repeated itself in teaching evaluations. Chief resident self-evaluators were more comfortable running a morning report (8.4) than with being chief resident (5.8). The feasibility of preparing internal medicine residents for leadership roles through a rotating PGY-3 (postgraduate year) chief residency curriculum was explored at a small internal medicine residency, and we suggest extending the study to include other programs.

    2016-08-01

    Over the past 25 years, the number of women graduating from medical schools in the United States and Canada has increased dramatically to the point where roughly equal numbers of men and women are graduating each year. Despite this growth, women continue to face challenges in moving into academic leadership positions. In this Commentary, the authors share lessons learned from their own careers relevant to women's careers in academic medicine, including aspects of leadership, recruitment, editorship, promotion, and work-life balance. They provide brief synopses of current literature on the personal and social forces that affect women's participation in academic leadership roles. They are persuaded that a deeper understanding of these realities can help create an environment in academic medicine that is generally more supportive of women's participation, and that specifically encourages women in medicine to take on academic leadership positions.

    The Benjamin H. Kean Fellowship in Tropical Medicine is an American Society of Tropical Medicine and Hygiene initiative that provides medical students with funding for international clinical or research experiences lasting at least 1 month. Of the 175 Kean fellows from 1998 to 2013, 140 had current available e-mails, and 70 of the 140 (50%) responded to a survey about their fellowship experience. Alumni indicated that the Kean Fellowship had a high impact on their career plans with regard to preparation for ( N = 65, 94.2%) and inspiration to pursue ( N = 59, 88.1%) a career in tropical medicine and global health. Continued involvement in tropical medicine and global health was common: 52 alumni (74.3%) were currently working in tropical medicine or global health, 49 (71.0%) had done so in the interim between the Kean fellowship and their current position; and 17 of 19 Kean fellows (89.4%) who had completed all medical training and were now in professional practice continued to work in tropical medicine and global health. Alumni had been highly productive academically, publishing a total of 831 PubMed-indexed manuscripts, almost all on tropical medicine or global health topics, in the period between their fellowship year and 2013. Alumni reported strengths of the fellowship including funding, networking, and flexibility, and suggested that more networking and career mentoring would enhance the program. The Benjamin H. Kean fellowship program has been highly successful at inspiring and fostering ongoing work by trainees in tropical medicine and global health.

    To analyze reasons for disapproval of registration application of new traditional Chinese medicines in recent years and discuss potential problems occurring in R&D and registration administration of new traditional Chinese medicines in China. All applications of new traditional Chinese medicines for registrations that had been disapproved by Center for Drug Evaluation of State Food Drug Administration from 2006 to 2008 were searched in data bank. Specific reasons for disapproval of each variety were inquired and sorted out. The statistics involved the proportion of each type (kind) disapproval reasons in all disapprovals in order to analyze which were the main reasons. The results were analyzed to find out potential problems occurring in R&D and registration administration of new traditional Chinese medicines in China. There were totally 247 disapproved registration applications for new traditional Chinese medicines. Among them, there were 218 applications for clinical trials and 29 applications for launch in the market There were 9 categories (29 types) of reasons for the applications for clinical trials applications, mainly including such problems as R&D proposal, non-clinical effectiveness and non-clinical safety; while there were 5 categories (9 types) of reasons for the applications for launch in the market, with clinical effectiveness as the main reason. There were many kinds of reasons for the disapproval registration applications of new traditional Chinese medicines in recent years in China, mainly including such problems as effectiveness, safety and proposal basis. This reflects problems occurring in R&D and registration administration of new traditional Chinese medicines in China to some extent.

    The present study provided a group learning activity called "Ambulatory Medicine Tutorial-AMT" for 5th year medical students in order to facilitate learning experience at ambulatory setting and to improve medical students' clinical performance. This research aimed specifically to study the effect of AMT. Two groups of twenty 5th-year medical students were enrolled during their ambulatory medicine blocks. Each medical student was assigned to have 8 ambulatory sessions. AMT was assigned to one group while the other group only used conventional learning activity. At the end of the present study, total internal medicine scores, patient satisfaction surveys, and data on average time spent on each clinical encounter were collected and compared. The AMT group received a higher total internal medicine score as compared to the conventional group (76.2 +/- 3.6 vs. 72.9 +/- 2.8, p = 0.003). The AMT group could reduce average time spent on each clinical encounter within their first-6 ambulatory sessions while the conventional group could acquire the same skill later in their last 2 ambulatory sessions. There was no significant difference found on comparing patient satisfaction scores between the 2 groups. AMT helped improving medical students' outcomes as shown from higher total internal medicine score as well as quicker improvement during real-life clinical encounters, AMT could be a good alternative learning activity for medical students at ambulatory setting.

    The authors presented an analysis of homicides based on autopsy material collected at Institute of Forensic Medicine in Bialystok in the years 1982-2003. Of 8,780 postmortem examinations, this type of death accounted for 7,4 % of cases, including 31,2 % women and 68,8 % men. Married individuals predominated among females, whereas the majority of male victims were single. Fifty-seven percent of victims died on the crime scene, 5,3 % within 48 hours. In conflicts of long-standing, immediate conflicts and fights, the perpetrators most commonly employed hard, blunt or blunt-edged crime weapons. In cases of murder with robbery and sexual homicides, strangulation was the most frequently used method. No seasonal character in homicide prevalence was observed.

  10. The American oil industry and the Fifty-Fifty Agreement of 1950

    Anderson, T.H.

    1988-01-01

    This paper traces the history of the Fifty-fifty Agreement of 1950, and the role of the American oil industry in that agreement. Regardless of the definition one chooses for the term foreign policy, it can now be argued with considerable force that the Fifty-fifty Agreement was, in fact, the product of American foreign policy. Defining the term narrowly as the enunciated policy of the Executive Branch of Government on matters outside the national boundary, it is clear that a consistent policy had been in place for a long time supporting exactly the type of action which was taken hear. Defining the term broadly, as the defacto cumulative thrust of all competing interest groups within a nation-state (both governmental and private) outside the national boundary, makes the assertion even more clear. Including Aramco and the parent companies in the equation leaves little doubt that the Fifty-fifty Agreement was the product of American foreign policy

    Full text: Changes were made to the content and mode of delivery of the Year 1 Nuclear Medicine degree program at The University of Sydney in 1996. Changes included increased study of skeletal, respiratory and cardiac Nuclear Medicine and the use of problem based learning to increase independent learning and clinical reasoning skills. Learning outcomes were qualitatively assessed to determine the educational value of the changes. The project aimed to evaluate whether changes made to the Year 1 program in 1996 raised clinical abilities of students entering their first clinical placement in Year 2. Retrospective surveys were conducted on both the 1995 and 1996 Year 1 students after completion of their first Year 2 clinical placement. Surveys were designed to assess the students perception of how well Year 1 had prepared them for both understanding and application of content studied in Year 1. Clinical Supervisors who assessed both cohorts of students were surveyed to determine if 1996 students presented with any appreciable difference in understanding and application to areas studied in Year 1. Results of the student survey indicated the 1996 students were more positive than the 1995 students about their clinical readiness. Clinical Supervisor survey results showed a positive response to the level of understanding and application of skills by the 1996 students. In conclusion, the 1996 Year 1 students were perceived to have a higher level of clinical abilities at the commencement of their Year 2 clinical placement. This result demonstrated worthwhile learning outcomes for the changes to content and mode of delivery in the Year 1 Nuclear Medicine degree program

    An Observed Structured Clinical Examination (OSCE) was integrated into the assessment for senior medical students undertaking a 4.5-week geriatric medicine teaching block at one campus. The feasibility and acceptability of an OSCE were examined. Students completed eight questions regarding the OSCE using a 6-point Likert scale and two additional questions, using free text, highlighting the strengths and potential areas for improvement. Changes were made every 6 months over a two-year period in response to student evaluation. Improvements included adjusting the format to conform with end-of-year examinations and introducing simulated patients. Following these improvements, students perceived improved structure and sequence to the assessments, improved opportunity for demonstration of skills and knowledge and that the assessment was fair. This preliminary research provides evidence that it is feasible to introduce OSCE as a form of assessment into a geriatric medicine teaching programme and student evaluation can be used to inform improvements. © 2016 AJA Inc.

    Generally, a student changes lifestyle when enters to the University, this can lead to different alimentary habits that could become as risk factors of nontransmissible chronic diseases (NTCD). To evaluate the presence of risk factors of NTCD in students of medicine race in Carabobo University. 120 people were evaluated, students of third to the sixth year of the medicine race, Carabobo University, year 2006. Family records, nutritional habits, alcohol and tobacco consumption were studied. Anthropometric measures, arterial pressure, glycemia and lipids sérics, were determined. Of evaluated students 68 they belonged to feminine sex and 52 masculine, age between 18 and 26 years old. The risk factor more frequent was the sedentary (72.49%), followed of alcoholic habits (68.3%) and smoking tobacco (34.16%). A 37.5% had high consumption of oils and fats, 58.3% starches and sugars. A 33.34% was overweight or obesity; 3.33% with high blood pressure and metabolic syndrome. The family antecedent predominant was high blood pressure (60%) and obesity (28.2%). In this student population risk factors for NTCD exist, which alerts on the necessity to restore plans of education and measures of primary prevention in order to diminish to future the appearance of NTCD in the students of the medicine race in Carabobo University.

    The educational needs of medical students in the 4th-year of training are not well defined in the literature. The specific aim of this investigation is to characterize the perceived educational needs of 4th-year medical students during an Emergency Medicine clerkship. This was a thematic analysis of informed self-assessment narratives. The writings were performed by medical students during an Emergency Medicine clerkship from July 2010 through May 2011. Themes and subthemes that emerged were assessed for frequency of occurrence. Qualitative analysis of 203 narratives revealed 13 themes and 55 subthemes. Patient care (50%), history taking (44%), and physical examination (29%) were the themes most commonly noted as strengths. Medical decision making/plan of care (44%), differential diagnosis (37%), presentation skills (32%), and knowledge base (27%) were the themes most commonly noted as weaknesses. All themes were described as strengths by some students and weaknesses by others; however, trends were apparent in the analysis. Fourth-year medical students rotating on an Emergency Medicine clerkship perceive an educational need to improve medical decision making/plan of care. Self-assessment narratives reveal trends in strengths and weaknesses but also highlight the importance of recognizing students as unique learners with individualized needs.

    Introduction Prior research shows that gaps exist in internal medicine residents’ critical care knowledge and skills. The purpose of this study was to compare the bedside critical care competency of first-year residents who received a simulation-based educational intervention plus clinical training to third-year residents who received clinical training alone. Methods During their first three months of residency, a group of first-year residents completed a simulation-based educational intervention. A group of traditionally-trained third-year residents who did not receive simulation-based training served as a comparison group. Both groups were evaluated using a 20-item clinical skills assessment at the bedside of a patient receiving mechanical ventilation at the end of their medical intensive care unit rotation. Scores on the skills assessment were compared between groups. Results Simulator-trained first-year residents (n=40) scored significantly higher compared to traditionally-trained third-year residents (n=27) on the bedside assessment, 91.3% (95% CI 88.2% to 94.3%) vs. 80.9% (95% CI 76.8% to 85.0%), P = simulation-based educational intervention demonstrated higher clinical competency than third-year residents who did not undergo simulation training. Critical care competency cannot be assumed after clinical ICU rotations; simulation-based curricula can help ensure residents are proficient to care for critically ill patients. PMID:23222546

    Young people attending genitourinary medicine services are at high risk of unplanned pregnancy. We performed a retrospective cohort study to identify characteristics of pregnant teenagers accessing an inner London genitourinary medicine service. There were 481 pregnancies in 458 teenagers with 54 previous pregnancies and 46 previous terminations of pregnancy. The under-18 and under-16 teenage pregnancy rates were 92.1 and 85.8 per 1000 age-matched clinic attendees, respectively. Median age was 17.1 years. 'Black Other' teenagers ('Black British', 'Mixed White-Black Caribbean' and 'Mixed White-Black African') were over-represented, compared to our clinic population, while those of White ethnicity were under-represented. Few pregnancies (1.5%) were planned with the majority (64%) intending terminations of pregnancy. Most teenagers did not use consistent contraception. Two-thirds of patients had attended genitourinary medicine services in the past and sexually transmitted infection prevalence at presentation was high. Effectively targeting the sexual and reproductive health needs of teenage genitourinary medicine clinic attendees may have a significant impact on reducing sexually transmitted infections, unplanned pregnancy and terminations of pregnancy in this group. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Previous work has shown American obstetrics and gynecology (OB/GYN) residents are lacking in menopause training. Our objective was to assess the effectiveness of a 2-year menopause medicine curriculum in improving OB/GYN residents' knowledge and self-assessed competency in menopause topics. We developed a menopause medicine-teaching curriculum for OB/GYN residents at our academic hospital-based residency program. The 2-year curriculum was composed of year 1: four 1-hour lectures and one 2-hour lab with cases presentations, and year 2: three 1-hour lectures and one 2-hour lab. Core topics included menopause physiology, hormone therapy, breast health, bone health, cardiovascular disease, and autoimmune disease. Pre- and posttests assessed resident knowledge and comfort in core topics, and a pre- and postcurriculum survey assessed utility and learning satisfaction. From July 2011 to June 2013, 34 OB/GYN residents completed the menopause curriculum annually with an average attendance at each module of 23 residents. Pre-/posttest scores improved from a mean pretest score of 57.3% to a mean posttest score of 78.7% (P menopause patients with 75.8% reporting feeling "barely comfortable" and 8.4% feeling "not at all comfortable." After the 2-year curriculum, 85.7% reported feeling "comfortable/very comfortable" taking care of menopause patients. The majority of residents (95.2%) reported the menopause curriculum was "extremely useful." A 2-year menopause medicine curriculum for OB/GYN residents utilizing lectures and a lab with case studies is an effective modality to improve resident knowledge required to manage menopause patients.

    Full Text Available Audience and type of curriculum: The Ohio State University Emergency Medicine Residency Program Musculoskeletal Emergencies Curriculum is a three-year curriculum for PGY-1 to PGY-3 learners. Introduction/Background: Musculoskeletal complaints/injuries compose a significant proportion of emergency department visits; in fact, many can result in significant morbidity. These conditions present in a vast array of acuities from minor to life/limb threatening. Emergency medicine physicians must be facile in diagnosing and managing various musculoskeletal conditions. We aim to present a three-year curriculum that incorporates clinical experience, self-directed learning, and small group-based didactics using the flipped classroom model to allow learners to master the diagnosis and management of musculoskeletal emergencies. This curriculum will provide progressive training in the diagnosis and management of musculoskeletal emergencies. Objectives: Resident learners will master the diagnosis and management of emergent musculoskeletal conditions including fractures/dislocations, soft tissue injuries, compartment syndrome, joint complaints, infections, and complex injuries. Methods: The educational strategies used in this curriculum include: independent, self-directed learning via textbook and medical literature reading, didactic sessions describing the diagnosis and management of musculoskeletal conditions, a four-week orthopedic surgery rotation, and an optional four-week rotation at a medical center-affiliated sports medicine practice. Residents are expected to actively participate in the care of patients with musculoskeletal conditions/injuries presenting to the emergency department during the course of their residency training. The time requirements, reading material, and diagnosis/management techniques taught vary depending on the year of training. Length of curriculum: The entirety of the curriculum is three years; however, each year of residency

    Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine. To this end, the committee formulated the objectives, content, evaluation system, and pedagogical methods to be used in those courses. The 25 self-teaching modules, together with the observation and practical interpretation of radiology sessions, proved highly useful in solving the initial problems, and were of particular interest to the students.

    The investigation clearly demonstrated statistically significant increases of risks for acute myeloid and lymphoid leukemia, chronic myeloid leukemia, and solid tumors including thyroid cancer, gastrointestinal cancers, lung cancer, hepatoma and skin cancer. The excess relative risks was highest for acute lymphoid leukemia, followed by chronic myeloid leukemia, acute myeloid leukemia, and solid cancer. The increased risk for leukemia has almost completely disappeared after 50 years, whereas the risks for cancers are apparently persisting giving a great threat to general health of atomic bomb survivors. These observations can be directly referred to the possible late effects of the acute and chronic exposure to irradiation caused by nuclear tests in Semipalatinsk region. Recent dose-estimation efforts by Kazakhstan, US and Japanese scientists indicated that there had been Hiroshima/Nagasaki atomic bomb equivalent high-dose exposure in some residents around the test sites. Some researchers suggested increased risks for malignant diseases such as leukemia and cancers. Unfortunately there was a lack of high-quality statistics in the Semipalatinsk survey, providing a considerable difficulty in interpreting the estimated incidences of such malignant diseases

    2015-09-01

    Over the past 30 years, the international conference on Artificial Intelligence in MEdicine (AIME) has been organized at different venues across Europe every 2 years, establishing a forum for scientific exchange and creating an active research community. The Artificial Intelligence in Medicine journal has published theme issues with extended versions of selected AIME papers since 1998. To review the history of AIME conferences, investigate its impact on the wider research field, and identify challenges for its future. We analyzed a total of 122 session titles to create a taxonomy of research themes and topics. We classified all 734 AIME conference papers published between 1985 and 2013 with this taxonomy. We also analyzed the citations to these conference papers and to 55 special issue papers. We identified 30 research topics across 12 themes. AIME was dominated by knowledge engineering research in its first decade, while machine learning and data mining prevailed thereafter. Together these two themes have contributed about 51% of all papers. There have been eight AIME papers that were cited at least 10 times per year since their publication. There has been a major shift from knowledge-based to data-driven methods while the interest for other research themes such as uncertainty management, image and signal processing, and natural language processing has been stable since the early 1990s. AIME papers relating to guidelines and protocols are among the most highly cited. Copyright © 2015 Elsevier B.V. All rights reserved.

    Reflective practice is a desirable trait in physicians, yet there is little information about how it is taught to or learned by medical students. The purpose of this study was to determine whether an online Evidence Based Medicine (EBM) exercise with a face-to-face debriefing session would prompt third year medical students to reflect on their current skills and lead them to further reflection on clinical decision making in the future. All third year medical students at the University Of Maryland School Of Medicine who completed their pediatrics clerkship between 7/1/09 and 2/11/11 were required to complete the EBM exercise. Following completion each student received a personal report (Learning Profile) of their responses and attended a one hour large group debriefing session. Student responses to a survey following the debriefing sessions were analyzed using a post-test survey design with a single experimental cohort. Ninety-five percent of students completing the debriefing survey indicated that the debriefing session helped them better understand their learning profiles; 68% stated that their profiles allowed them to evaluate themselves and their decisions. Sixty-three percent noted that participating in the exercise and the debrief would lead them to either learn more about EBM and use EBM more in the future or reflect more on their own decision making. The EBM exercise was a successful way to introduce the concept of reflective practice to third year medical students, and the graphic Learning Profiles were effective instigators of discussion and reflection.

    2007-01-01

    This work describes the audiometry threshold assessment of 1000 workers employed in different artisan categories during a period of ten-year noise professional exposure. The hearing loss noise-induced rates were determined by analysing audiometric tests at the beginning of our period of study and after 5 and 10 years of noise exposure. Environmental noise exposures were on average 88 dB(A), but near 90 dB(A) in some work categories. Workers widely used hearing protection devices, nearly at 93%, during the period we studied. The Evidence Based Occupational Medicine should find out points of reference proving the efficiency and effectiveness of occupational physicians: in this case, a positive trend in the reduction of hearing loss rate will be expected to confirm the goodness of prevention practice. Our study suggests that the levels of protection so far accepted are not effective enough in order to reduce the incidence of noise-induced hearing loss in the course of the years: in despite of most accredited predicting models for hearing conservation programs, a significant percentage of workers exposed to industrial noise continues to present a high incidence of hearing loss. The Evidence Based Occupational Medicine suggests that the proposed prevention activities carried out in the described factories were not enough effective.

    A total of 292 adverse reactions to veterinary medicinal products were reported during the year 2015. This represents an increase of 9% compared to the previous year (268 reports). Similar to previous years, most of the reactions reported were linked to the use of antiparasitics (55.1%), non-steroidal anti-inflammatory products (8.9%) or antiinfectives (9.3%). The affected animal species were primarily dogs (198 reports) and cats (42 reports), followed by cattle (31 reports) and horses (8 reports). Additional 42 reports were provided within the frame of consultations with Tox Info Suisse in Zürich and involved mainly the excessive intake of flavored tablets. Eight signals were identified from the reports received or the periodic safety update reports. They resulted in revisions of the product information in sections addressing contraindications, adverse reactions or withdrawal times.

    During the year 2009, 134 reports of suspected adverse drug reactions (ADRs) to veterinary medicinal products (VMPs) were received (106 in the year 2008). The distribution according to species and drug classes remained in line with previous years. Companion animals were involved in most of the reports (46 % dogs, 19 % cats), followed by cattle or calves (22 %). Antiparasitic drugs made the biggest part with 30 % of the reports, followed by antiinfectives (19 %) and hormones (13 %). Some reactions following their use are specifically discussed. 95 additional enquiries about ADRs of VMPs were received by the Swiss Toxicological Information Centre in Zürich. Most of them concerned dogs or cats and antiparasitics or anti-inflammatory drugs. In the vaccinovigilance program, a total of 1020 reports were received, of which 1000 were related to the vaccination against blue tongue disease. The most frequently reported adverse reactions were aborts, mastitis or alterations of milk quality and they are specifically discussed.

    1995-01-01

    The Met Lab at the University of Chicago was established to build the world's first nuclear reactor. The object was to see if a pile (CP-1) could be built to create a sustained chain reaction, i.e., controlled nuclear fission. New materials of the very best quality were needed and people of many skills worked together to achieve the goal as quickly as possible. This is the story of a select group of people who were scientific and engineering pioneers in this new field. Research continued at new sites on more advanced reactors and cooling systems. Many problems were encountered in the fabrication of reactor components, and metallography was a crucial method of analyzing the reactions and quality of consolidation. 1996 will be the 50th anniversary of the beginning of the National Laboratories, so it is appropriate to commemorate and recall some pioneering achievements

    This report is the written version of a colloquium first presented at Argonne National Laboratory in January 1989. The paper begins with an historical preamble about the events leading to the discovery of nuclear fission. This leads naturally to an account of early results and understanding of the fission phenomena. Some of the key concepts in the development of fission theory are then discussed. The main theme of this discussion is the topography of the fission barrier, in which the interplay of the liquid-drop model and nucleon shell effects lead to a wide range of fascinating phenomena encompassing metastable isomers, intermediate-structure effects in fission cross-sections, and large changes in fission product properties. It is shown how study of these changing effects and theoretical calculations of the potential energy of the deformed nucleus have led to broad qualitative understanding of the nature of the fission process. 54 refs., 35 figs

    The fiftieth anniversary celebration has this characteristic which it makes it possible to carry a retrospective glance on the evolution of a subject. From this point of view, the LASER, as a scientific concept or a technological tool, does not escape the rule. This article recalls the historical contributions leading to the first demonstration of the laser effect by Theodore Maiman in 1960, starting from a theoretical concept established by Albert Einstein in 1917. This demonstration naturally opened a strong activity in the laboratories. It resulted in the creation of instruments which took part in the enrichment of knowledge in the fields of physics, chemistry and the biomedical one. In our daily life, the communications, the information storage, the imagery, lighting and the industrial tools profited from the properties of the coherent or quasi-coherent emission of the light. Each one of these applications to follow-up its own evolutions which we will also try to describe in this article. (author)

    Arising stressors from both global and local sources threaten coral reefs, with studies indicating that local and global sources might reduce coral resilience. Local sources include sediment stress and nutrient stress from fishing; global sources include increasing sea surface temperature and ocean acidification. Through an in-depth review and re-analysis of published work, conducted under the scope of a course in the spring of 2017 semester and follow up research over the summer of 2017 and fall of 2017, students in Environmental Studies Course, ENVS 4100: Coral reefs, at the University of Colorado Boulder have developed a framework to initiate a discussion of global and local policies focused on protection of coral reefs. The research aims to assess current threats and suggest mitigation efforts. The paper uses secondary research to analyze impact of ocean acidification on aragonite saturation levels, current thermal stress, nutrient stress, and sediment factors that influence the health of coral and its surrounding ecosystem over the Common Era. Case studies in this paper include the Caribbean and Red Sea coral reefs, due to the variation of the atmosphere, temperature, and human activity in these regions. This paper intends to offer sufficient evidence that will lead to appropriate policy decisions that pertain to reef conservation.

    In May of 1962, due to the explosions carried out by the Commission of Atomic Energy of the United States in the Christmas Island, a group of professionals of the 'Junta de Control de Energia Atomica' of Peru, created in 1957, carried out experimental evaluations of atmospheric radioactivity, obtaining acceptable results regarding those of Naval US Research Laboratory, this was the beginning of the Laboratory of Atmospheric Radioactivity that begins to operate permanently in February of 1964. In 1966, France began a program of nuclear tests in the French Polynesian, generating concern due to the meteorological conditions that could affect the peruvian population. With the support of experts and equipments on the part of the government from France, the Laboratory of Environmental Radioactivity began their activities in August of 1966. At the present time, the Laboratory of Environmental Radioactivity is located in the Nuclear Center RACSO of the 'Instituto Peruano de Energia Nuclear' and it carries out the following programs: Radiological Environmental Surveillance in the Influence Area of the Nuclear Center, Nationwide Radiological Environmental Surveillance, Marine Radiological Environmental Surveillance, Radiological Environmental Surveillance in the Peruvian Antarctic Region and Surveillance of the Radioactive Contamination of Foods. The results of the evaluations of the programs of radiological environmental surveillance, developed nationwide from 1962, show one gradual decrease of the levels of environmental radioactivity. Significant concentrations of Cs-137 and Be-7 were found in the Antarctic region, and, in the area of influence of the nuclear center RACSO, environmental discharges of I-131, Cs-137, Co-60, Cs- 134 and Te-123m were detected, however, the concentrations did not present radiological risk for the population.

    With the commemoration in October 2007 of the Sputnik launch, space exploration celebrated its 50th anniversary. Despite impressive technological and scientific achievements the fascination for space has weakened during the last decades. One contributing factor has been the gradual disappearance of mankind's hope of discovering extraterrestrial life within its close neighbourhood. In striking contrast and since the middle of the 20th century, a non-negligible proportion of the population have already concluded that intelligent beings from other worlds do exist and visit Earth through space vehicles popularly called Unidentified Flying Objects (UFOs). In light of the continuous public interest for the UFO enigma symbolized by the recent widely diffused media announcements on the release of French and English governmental files; and considering the approach of broadening the strategies of the "Active SETI" approach and the existence of a rich multi-disciplinary UFO documentation of potential interest for SETI; this paper describes some past scientific attempts to demonstrate the physical reality of the phenomena and potentially the presence on Earth of probes of extraterrestrial origin. Details of the different instrumented field studies deployed by scientists and organizations during the period 1950-1990 in the USA, Canada and Europe are provided. In conclusion it will be argued that while continuing the current radio/optical SETI searches, there is the necessity to maintain sustaining attention to the topic of anomalous aerospace phenomena and to develop new rigorous research approaches.

    To describe the evolution of non-alcoholic and alcoholic beverages consumption in the Spanish households from the 60's to nowadays. This study is based on beverages and food consumption in Spanish households; the data sample consisted of consumption and distribution data, obtained from the Household Budget Survey (HBS) since 1964 to 1991 and from the Food Consumption Survey (FCS) since 2000 to 2014, in collaboration with the Spanish Nutrition Foundation (FEN). In 2014 the average consumption of non-alcoholic beverages was 332 g/person/day, whereas alcoholic beverages consumption represented 72.6 g/person/day. Consumption of non-alcoholic beverages has increased 721% (1964: 46 g/person/day; 1991: 96 g/person/day; 2000: 240 g/person/day and 2014: 332 g/person/day), whereas alcoholic beverages consumption has decreased roughly a 50% (1964: 145 g/person/day; 1991: 113 g/person/day; 2000: 78.4 g/person/day and 2014: 72.6 g/person/day). The most consumed alcoholic beverage in 2014 was beer (41.3 g/day), followed by wine (23.0 g/day). Regarding non-alcoholic beverages, the most consumed was water (144 g/day), followed by cola (ordinary: 30.7 g/day and diet: 20.5 g/day).According to Spanish regions, in 2014 non-alcoholic beverages were the most consumed in the islands (Balearic Islands 521 grams/person/day; Canary Islands 515 grams/person/day), as it was in the nineties (Balearic Islands 148 grams/person/day and Canary Islands 281 grams/person/day). However in 1980-81 the largest consumption of alcoholic beverages was that of Galicia, 408 g/person per day, and the lower in the Canary Islands, 63 g/person per day. In 2014, Murcia and Andalucía represented the regions with the highest consumption of alcoholic beverages. In 2014, alcoholic beverages provided roughly 1.89% of the total energy and 1.47% of sugars, whereas non-alcoholic beverages provided 3.28% of energy and 15.72% of sugars and, in 2000, alcoholic beverages contributed 2.29% of the energy and 1.47% of sugars and non-alcoholic drinks provided 3.76% of the energy and 22.7% of sugars. There have been signifi cant changes in the eating patterns at the Spanish homes, especially regarding beverages consumption, over the last five decades. In general, a higher consumption and variety for non-alcoholic drinks has occurred, especially in the islands. In parallel, a decline in alcoholic beverages consumption has been clearly observed.

    From 1963 to 2014, the Los Alamos National Laboratory was involved in at least 233 spacecraft. There are probably only one or two institutions in the world that have been involved in so many spacecraft. Los Alamos space exploration started with the Vela satellites for nuclear test detection, but soon expanded to ionospheric research (mostly barium releases), radioisotope thermoelectric generators, solar physics, solar wind, magnetospheres, astrophysics, national security, planetary physics, earth resources, radio propagation in the ionosphere, and cubesats. Here, we present a list of the spacecraft, their purpose, and their launch dates for use during RocketFest

    Becklin, Eric Eric

    2018-01-01

    My adventures in infrared astronomy started when I was a grad student in 1965 with the discovery of an infrared-bright object (now known as the Becklin-Neugebauer Object) in the Orion Nebula. In 1966, I made the first measurements of the infrared radiation from the center of the Milky Way Galaxy. I was fortunate enough to be able to take advantage of the 2.2 micron sky survey carried out by Neugebauer and Leighton (1969), which produced many remarkable discoveries, the most spectacular being the heavily dust-embedded carbon star IRC+10216, thebrightest object in the sky at 5 microns outside the solar system. In the 1970’s there was a growth in Infrared astronomy with the availability of many new facilities such as the Kuiper Airborne Observatory, (KAO) which I used extensively with Mike Werner and Ian Gatley for many unique observations. In 1977, I moved to Hawaii to work on the NASA IRTF 3- meter telescope. Many discoveries were made, including the first direct measurements of the rings of Jupiter at 2.2 microns (with Gareth Wynn-Williams) and the discovery of the first L dwarf star around a white dwarf (with Ben Zuckerman). In the 1980’s the introduction of large format arrays changed the way we did infrared astronomy. With Ian McLean, I moved to UCLA in 1990 to start the IR lab and get involved in Keck development and science. In 1995, Andrea, Ghez, Mark Morris and I started looking for evidence of a possible massive Black Hole in the Galactic Center. Spectacular observations using the Keck10 meter telescopes with large format near-infrared arrays and adaptive optics led to the confirmation of the presence of such a black hole and an estimate of its mass (4xE6 M (Sun)). In 1996, I began working on the Stratospheric Observatory For Infrared Astronomy (SOFIA) and I will finish my talk by discussing SOFIA observations of the ring of dust and gas orbiting the massive black hole in the center

    Butrica, Andrew J. (Editor)

    1997-01-01

    The three overlapping stages of satellite communications development outlined provide the three-part framework for the organization of the papers contained in this book. Part 1, 'Passive Origins,' treats the first stage of satellite communications development, extending from the 1940s into the early 1960s, when passive artificial and natural satellites funded by the military and private enterprise established the field. Part 2, 'Creating the Global, Regional, and National Systems,' addresses events that constituted the second stage of development. Early in this stage, which stretched from the 1960s into the 1970s, satellite systems began to make their appearance in the United States, while domestic and international efforts sought to bring order to this new but chaotic, field in the form of Comsat and Intelsat. Part 3, 'The Unfolding of the World System,' explores the development of satellite communications in the remainder of the world, with a strong emphasis on Asia.

    Objective To report on the career intentions, three years after qualification, of 12 national cohorts of UK-trained doctors who qualified between 1974 and 2012, and, specifically, to compare recent UK medical graduates' intentions to work in medicine in the UK with earlier graduates. Design Questionnaire surveys of cohorts of UK medical graduates defined by year of graduation. Setting UK. Participants 30,272 UK medical graduates. Main outcome measures Stated level of intention to pursue a long-term career in medicine in the UK. Results The response rate was 62% (30,272/48,927). We examined responses to the question ' Apart from temporary visits abroad, do you intend to practise medicine in the United Kingdom for the foreseeable future?' Of doctors from UK homes, 90% had specified that they would 'definitely or probably' practise medicine in the UK in the surveys of 1977-1986, 81% in 1996-2011 and 64% in 2015. Those who said that they would probably or definitely not practise medicine in the UK comprised 5% in 1977-1986, 8% in 1996-2011 and 15% in 2015. Most who were not definite about a future career in UK medicine indicated that they would wish to practise medicine outside the UK rather than to leave medicine. Conclusions The wish to remain in UK medical practice in the 2015 survey was unprecedentedly low in this unique series of 40 years of surveys.

  20. Imperial Medicine in a Changing World: The Fourth International Congresses on Tropical Medicine and Malaria, 1948.

    2016-01-01

    The close connections between colonialism and tropical medicine have been widely discussed by historians over the last fifty years. However, few authors consider the relationship between tropical medicine and European and North American imperialism in the immediate post-World War II period. This article examines the Fourth International Congresses on Tropical Medicine and Malaria, held jointly in Washington in 1948. Using the research presented during the conference, it questions to what degree the specialisation had changed in the postwar period. It argues that although some changes are discernable, imperial traditions and relationships remained firmly embedded within the tropical medicine of the congress.

    A total of 253 reports of adverse reactions to veterinary medicinal products were received during the year 2016 representing a decrease of 13% compared to the previous year (292 reports). The majority of the reports described reactions affecting companion animals (178 dogs and 32 cats) as well as cattle (17 reports) and horses (10 reports). Most of the reactions reported were linked to the use of antiparasitics (145 reports), hormone products (26 reports) and antiinfectives (10 reports). 32 reports were generated from consultations with Tox Info Suisse in Zürich and involved mainly the excessive intake of flavoured tablets and, in some cases, the use of reconverted products (applied to another species than that authorized). Five signals were identified from the reports, which resulted in revisions of the product information in the sections addressing contraindications or adverse reactions.

    Burnout is a common issue in internal medicine residents, and its impact on medical errors and professionalism is an important subject of investigation. To evaluate differences in medical errors and professionalism in internal medicine residents with and without burnout. A single institution observational cohort study was conducted between June 2011 and July 2012. Burnout was measured using the Maslach Burnout Inventory to generate subscores for the following 3 domains: emotional exhaustion, depersonalization, and sense of personal accomplishment. By convention, burnout was defined as a high emotional exhaustion or depersonalization subscore. Medication prescription error rate was the chosen measure of medical errors. Professionalism was measured cumulatively through examining discharge summaries completed within 48 hours, outpatient charts completed within 72 hours, and the average time to review outpatient laboratory tests. Of a total of 54 eligible first-year residents, 53 (98%) and 32 (59%) completed the initial and follow-up surveys, respectively. Residents with year-end burnout had a lower rate of medication prescription errors (0.553 versus 0.780, P  = .007). Discharge summaries completed within 48 hours of discharge (83.8% versus 84.0%, P  = .93), outpatient charts completed within 72 hours of encounter (93.7% versus 94.3%, P  = .31), and time (minutes) to review outpatient laboratory test results (72.3 versus 26.9, P  = .28) were similar between residents with and without year-end burnout. This study found a small decrease in medical errors in residents with year-end burnout compared to burnout-free residents and no difference in selected measures of professionalism.

    Emergency medicine has been identified as the specialty that has gained the most young physicians who have changed their careers. To identify factors that may have contributed to such career changes, the authors compared the characteristics of three groups of physicians trained at their medical school: those who chose and stayed in emergency medicine, those who migrated into emergency medicine from other specialties, and those who moved out of emergency medicine. A prospective longitudinal study was conducted. The sample consisted of physicians who chose emergency medicine as their careers at graduation and stayed in the specialty (n = 24), those who migrated from other specialties into emergency medicine (n = 51), and those who moved out of emergency medicine (n = 10). This sample was obtained from a total of 2,173 graduates of Jefferson Medical College between 1978 and 1987. The three groups of physicians were compared according to their academic performances both during medical school and after graduation. The dependent variables were freshmen and sophomore grade point averages (GPAs), written clinical examination scores, scores on National Board of Medical Examiners examination (Parts I, II, and III), and residency program directors' ratings. Age and indebtedness at medical school graduation and board certification status also were examined. Those physicians who stayed in emergency medicine and those who migrated from other specialties into emergency medicine had similar measures of academic performance, but both of these groups had higher academic performance measures and higher board certification rates than did the physicians who moved out of emergency medicine. Those who stayed in emergency medicine had the highest mean debt in the senior year of medical school. High academic performance and high indebtedness are factors associated with choosing or staying in the specialty of emergency medicine.

    Full Text Available This exploration of the debates that have taken place in fandom over the ethics of pulling fan fiction and publishing it as original work draws on the notion of the fannish gift economy, which postulates that gifts such as fan fiction and fan art have value in the fannish community because they are designed to create and cement its social structure. Tension exists between fans who subscribe to the notion of a fannish gift economy and those who exploit fandom by using it to sell their pulled-to-publish works. An examination of E. L. James's 2012 Fifty Shades trilogy (comprising the books Fifty Shades of Grey, Fifty Shades Darker, and Fifty Shades Freed, which began as Twilight fan fiction, in addition to Twilight fan art sold through sites such as Redbubble and Etsy, demonstrates a tension between the two modes of fan expression: sale of artworks appears to be an acceptable practice in fandom, but the commercial sale of fan fic, even when marketed as original fiction, is widely contested.

    Tissue engineering (TE) is continuously evolving assimilating inputs from adjacent scientific areas and their technological advances, including nanotechnology developments that have been spawning the range of available options for the precise manipulation and control of cells and cellular environments. Simultaneously, with the maturation of the field, TE has a growing and marked impact in other fields, such as cancer and other diseases research, enabling tri-dimensional (3D) tumor/tissue models of increased complexity that more closely resemble living tissue dynamics, playing a decisive role in the development of new and improved therapies. Nevertheless, TE is still struggling with translational issues. On this matter, the advent of personalized and precision medicine has opened new perspectives, particularly with the striking evolutions enabled by 3D bioprinting technologies. Based on a modified methodology grounded in the past years' approach, we have identified and reviewed some of the most high-impact publications on the topics that are revolutionizing TE and helping to define the future directions of the field, namely: (1) New trends in TE: Personalized/precision regenerative medicine and 3D bioprinting, (2) Contributions of TE to other fields: microfabricated tissue-engineered 3D models for cancer and other diseases research, and (3) Diagnostic and theranostic tools: monitoring and real-time control of TE systems.

However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective.Purpose: To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors.Methods: A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80. The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants. The discussions were analyzed using content analysis.Results: The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available.Conclusion: On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward.

    Version 1 (V1) of the National Emergency Medicine Fourth-year Student (EM M4) Examination was released in 2011 and revised along with release of V2 in 2012. Each examination contains 50 multiple-choice questions designed to assess knowledge in the EM M4 clerkship curriculum. Development and initial performance data were described previously. To provide updated V1 performance data, describe development and revision of V2, and to compare performance between academic years and examination forms, and within academic years. Examinations are administered at www.saemtests.org with ongoing performance data provided. After 1 year of use, nine questions on V2 were revised, five because of low discriminatory ability and four because of excessive difficulty. Revision or replacement was done in accordance with the National Board of Medical Examiners (NBME) Item Writing Guidelines. Mean scores were compared for V1 between academic years (i.e., July 2011-June 2012 vs. July 2012-June 2013), V2 compared with V1, and for each examination version for early and late test takers. V1 has been administered >10,000 times since its release, and the current form mean is 81.5% (SD 3.7). Average discriminatory value (rpb) is 0.204. V2 has been administered >1500 times, with a mean score of 78.4% (SD 4.4) and average rpb 0.253. V1 and V2 current means differ statistically. Scores from examinees completing V1 or V2 early vs. late in the academic year differ statistically. Performance data for V1 remain stable after 2 years. Revisions of poorly performing questions improved question performance on V2. Questions with low rpb or low pdiff will continue to be revised annually. While examination forms differ statistically, the practical utility of the differences is not defined. Copyright © 2016 Elsevier Inc. All rights reserved.

    2009-01-01

    Fifty-five gallon drums are routinely used within the U.S. for the storage and eventual disposal of fissionable materials as Transuranic or low-level waste. To support these operations, criticality safety evaluations are required. A questionnaire was developed and sent to selected Endusers at Hanford, Idaho National Laboratory, Lawrence Livermore National Laboratory, Oak Ridge and the Savannah River Site to solicit current practices. This questionnaire was used to gather information on the kinds of fissionable materials packaged into drums, the models used in performing criticality safety evaluations in support of operations involving these drums, and the limits and controls established for the handling and storage of these drums. The completed questionnaires were reviewed and clarifications solicited through individual communications with each Enduser to obtain more complete and consistent responses. All five sites have similar drum operations involving thousands to tens of thousands of fissionable material waste drums. The primary sources for these drums are legacy (prior operations) and decontamination and decommissioning wastes at all sites except Lawrence Livermore National Laboratory. The results from this survey and our review are discussed in this paper

    At the department of nuclear medicine of the University Hospital Utrecht a single-modality PACS has been operational since mid-1990. After one year of operation the functionality, the organizational and economical consequences, and the acceptability of the PACS were evaluated. The functional aspects reviewed were: viewing facilities, patient data management, connectivity, reporting facilities, archiving, privacy, and security. It was concluded that the improved quality of diagnostic viewing and the potential integration with diagnosis, reporting, and archiving are highly appreciated. The many problems that have occurred during the transition period, however, greatly influence the appreciation and acceptability of the PACS. Overall, it is felt that in the long term there will be a positive effect on the quality and efficiency of the work.

    Transfusion guidelines advocate restrictive rather than liberal use of red blood cells (RBC) and are based mostly on randomized trials in intensive care and surgical departments. We aimed to study RBC transfusion practice in the medical patients' population. The data in this study were collected from patients over the age of 18 years admitted to an Internal Medicine department between 2009 and 2014 who received at least one unit of packed red blood cells (RBC). In addition, data on demographics, patients' diagnoses, laboratory tests and number of transfused RBC units were extracted from the electronic health records. One thousand three hundred and twenty eight patients were included, having mean age of 75 ± 14 years. The median hemoglobin (Hb) trigger for RBC transfusion was 8.0 g/dl (IQR 7.3-8.7g/dl), and most patients received either one (43.4%) or two (33.4%) RBC units. There was no significant difference in Hb trigger between males and females (Hb 8.0 g/dl and 7.9 g/dl, respectively, p = 0.098), and a weak correlation with age (r = 0.108 p = 0.001). Patients with cardiovascular and lung diseases had a statistically significant higher Hb trigger compared to patients without those diagnoses, however the median difference between them was 0.5 g/dl or less. These "real world" data we collected show a Hb trigger compliant with the upper limit of published guidelines and influenced by medical patients' common diagnoses. Prospective trials addressing patients hospitalized in internal medicine departments could further contribute to transfusion decision algorithms.

    The validity of children's self-reports on medicine use has not been reported. To determine the agreement between parents' and children's reports of medicine use for 5 common complaints and to analyze predictors for disagreement. We used the child-parent validation survey from the research project Health Behaviour in School-Aged Children. Three hundred ninety-three 11- and 13-year-old Danish children and their parents responded to identical questionnaires. The main outcome measures were self-reported medicine use during the previous month for headache, stomachache, difficulties in falling asleep, nervousness, and asthma. The percent agreement was lowest with medicine use for headache (64.6%), but was very high for the other 4 complaints (85.3-91.8%). The simple kappa coefficients were moderate to good for medicine use for headaches, stomachache, and asthma (0.31-0.58) but poor for difficulties in falling asleep and nervousness. Children who had the specific complaint during the previous month were more likely than their parents to report more frequent medicine use. We have some confidence in young adolescents' self-reports of medicine use, as the results of this study are in keeping with other studies on the validity of children's reports of health-related behaviors. Furthermore, the findings suggest that such data can be used in epidemiologic studies that aim to categorize children into groups with and without medicine use.

    Department of Anesthesiology, Faculty of Medicine Siriraj Hospital, has started to be a formal anesthesia division, divided from division of Surgery in 1965; hence our 50th year anniversary in 2015. Research is now a priority and mandatory mission, according to the vision of Mahidol University. Second mission is to teach and train, and we produce the highest number of states-of-the-art anesthesiologists and anesthetic nurses each year Curriculum and training are being continuously improved. From a small unit, now it is one of the largest departments and extends the service, our third mission, to more than only in the operating theaters. We look after pre-anesthesia assessment, inside and outside operating room anesthesia, post-operative pain relief Intensive Care Unit, and chronic pain management. The number of patients and their diseases increase; so do the complexities of surgeries. There are tremendous changes in drugs and equipment. There is the fourth mission on administration, IT and resource management. And the fifth mission which is corporate social responsibility. However, we still believe that compassion, responsibility and integrity are most important. We have taught and tried to live by the teaching of HRH the King's Father. And these will contribute to our progress and shine in the next 50 years.

    Full Text Available Abstract Background There are increasing expectations for primary care practitioners to deal with mental health problems. In Hong Kong, 15 % of the general public consult Traditional Chinese Medicine (TCM practitioners regularly for their primary health care needs. This study investigated the 5-year outcomes of a western mental health training course for TCM practitioners in Hong Kong. Method Structured questionnaire surveys were conducted to compare the TCM practitioners’ confidence and engagement in mental health care before and after the Course. The data collected during 2011–2015 were analyzed. Results A total of 151 TCM practitioners returned both pre- and post-Course questionnaires, with a response rate of 95.6 %. After the course, there were significant increases in the proportions of participants being confident of recognizing patients with psychological problems (62.9 % before the course vs 89.4 % after, diagnosing common mental health problems (47.7 % vs 77.5 %, and managing them (31.2 % vs 64.3 %. Overall, 66.9 % of the participants reported some increase in their confidence in recognizing patients with psychological problems, diagnosing or/and managing patients with common mental health problems. Qualitative responses illustrated the major improvements were increased awareness of mental symptoms, better understanding of classification of mental disorders and management approaches. On the other hand, barriers included difficulties in understanding medical terms in English, consultation time constraints, and a lack of formal referral system to psychiatrists. Conclusions The Course has positive impact on TCM practitioners in handling mental health patients. The findings are useful for designing similar trainings on complementary and alternative medicine practitioners in other countries.

    Patients are particularly susceptible to medical error during transitions from inpatient to outpatient care. We evaluated discharge summaries produced by incoming postgraduate year 1 (PGY-1) internal medicine residents for their completeness, accuracy, and relevance to family physicians. Consecutive discharge summaries prepared by PGY-1 residents for patients discharged from internal medicine wards were retrospectively evaluated by two independent reviewers for presence and accuracy of essential domains described by the Joint Commission for Hospital Accreditation. Family physicians rated the relevance of a separate sample of discharge summaries on domains that family physicians deemed important in previous studies. Ninety discharge summaries were assessed for completeness and accuracy. Most items were completely reported with a given item missing in 5% of summaries or fewer, with the exception of the reason for medication changes, which was missing in 15.9% of summaries. Discharge medication lists, medication changes, and the reason for medication changes--when present--were inaccurate in 35.7%, 29.5%, and 37.7% of summaries, respectively. Twenty-one family physicians reviewed 68 discharge summaries. Communication of follow-up plans for further investigations was the most frequently identified area for improvement with 27.7% of summaries rated as insufficient. This study found that medication details were frequently omitted or inaccurate, and that family physicians identified lack of clarity about follow-up plans regarding further investigations and visits to other consultants as the areas requiring the most improvement. Our findings will aid in the development of educational interventions for residents.

    A National Board of Medical Examiners examination does not exist for Emergency Medicine (EM) students. To fill this void, the Clerkship Directors in Emergency Medicine tasked a committee with development of an examination for 4th-year (M4) EM students, based on a published syllabus, and consisting of questions written according to published question-writing guidelines. Describe examination development and statistics at 9 months. The committee reviewed an existing EM student question database at www.saemtests.org for statistical performance, compliance with item-writing guidelines, and topic inclusion within the published EM M4 syllabus. For syllabus topics without existing questions, committee members wrote new items. LXR 6.0 software (Applied Measurement Professionals, Inc., Georgetown, SC) was used for examination administration. Data gathered included numbers of examinations completed, mean scores with SD, and point biserial correlation (rpb). Of the 553 questions assessed, 157 questions met the stated criteria, and 37 were included in the examination. Thirteen new questions were written by committee members to cover all curriculum topics. The National EM M4 Examination was released online August 1, 2011. Nine months later, the examination had been completed 1642 times by students from 27 clerkships. Mean score was 79.69% (SD 3.89). Individual question difficulties ranged from 26% to 99%. Question rpbs ranged from 0.067 to 0.353, mean 0.213 (SD 0.066). A national group of EM educators developed an examination to assess a published clerkship syllabus. The examination contains questions written according to published item-writing guidelines, and exhibits content validity, appropriate difficulty levels, and adequate question discriminatory ability.

    Professionalism and empathy are crucial in clinical settings. An association would be expected between empathic attitudes and altruistic motivations for a medical education. However, data is scarce in first-year students, and a previous small-scale study did not fully confirm the hypothesis that person-oriented motives would have a strong relationship to empathy. The present study tested this association in a larger sample. 202 first-year medical students (M age = 19.0 yr., SD = 2.7; 67.3% women) were assessed cross-sectionally, using the Vaglum and colleagues' indexes on motives for choosing medicine (security/status, person-orientation, and interest in the natural sciences) and the Jefferson Scale of Physician Empathy for students. There was a weak association between empathy and person-orientation, but the evidence regarding links between empathy and the three motivation scores was low overall. In this Portuguese sample there was not a clear-cut association between empathy and motivations for medical school.

    The final part of this series attempts to evaluate the relevance of Nazi medicine for doctors today. Euthanasia, informed consent, the conflict of interests of the individual versus those of society and racism were as prominent themes of Nazi medicine as they are today. It would be foolish not to learn from experiences of the past. Nazi medicine can therefore never be an irrelevant subject of the days gone by.

    This study has two purposes. The first is to explore an instrument of evaluation of the approaches to study (deep, strategic, and surface) adopted by students in the pre-clinical years of their veterinary degree program. The second is to examine relationships between these approaches and a broad range of further factors deemed relevant to the veterinary medicine context. We envisage that a greater knowledge of how these students learn will aid curriculum reform in a way that will enrich the learning experience of veterinary students. A questionnaire consisting of the 52-question Approaches to Study Inventory (ASI) and an additional 49 questions relating mainly to teaching, assessment, and study skills was distributed to 215 veterinary medicine (MVB) students in their pre-clinical years of study. Factor analysis was used to ensure that the ASI section of the questionnaire maintained previously reported structure. The internal reliability of the approaches measured was tested using Cronbach alpha analysis. The approaches were described as frequency distributions. Associations between the parameters (deep, strategic, and surface) and 49 additional context-specific factors were investigated using loglinear analysis. (1) Factor analysis revealed that the integrity and structure of the instrument in this context was generally comparable to previous studies. (2) The impact of a high workload was evident in the surface approach, with fear of failure becoming a strong motivating factor and syllabus boundness a widely used strategy. (3) Associations made between the approaches and 49 context-specific factors showed strong associations between both workload and lack of prior knowledge with the surface approach. (4) Grades were associated positively with both the deep and strategic approaches but negatively with the surface approach. (5) A range of learning and study skills were associated positively with the deep and strategic approaches and negatively with the surface

    The role of sports in decreasing the prevalence of many diseases has led to a growing interest in the field of sport and exercise medicine. But sport and exercise medicine still remains new to the Arab world, waiting to be explored. The aim of this study is to describe and characterise sport and exercise medicine research activity in the Arab world between 2002 and 2016. The PubMed database was used to search for publications related to sport and exercise medicine. Publications were classified according to the country of origin and filtered to include publications between 2002 and 2016. Research output was analysed with respect to gross domestic product (GDP) and population of each country. A total of 1148 papers related to sport and exercise medicine were found to be published in the Arab countries between 2002 and 2016. Sport-and-exercise-medicine-related publications constituted 0.86% of the total biomedical research papers published in the Arab world and 0.49% of the world's sport and exercise medicine literature. The number of sport-and-exercise-medicine-related publications per country ranged from zero to 352, with Qatar occupying the top spot. Tunisia ranked first with respect to publications per average GDP, while Qatar ranked first with respect to publications per average population. Comoros, Mauritania, Somalia, Sudan and Yemen were found to have no publications related to sport and exercise medicine. Sport and exercise medicine is a novel field in the Arab world. Recognising the barriers facing sport and exercise medicine research and exploring them meticulously remains an essential part of the plan to improve the Arab world's output and contribution in this field.

At the School of Medicine in Split (Croatia we organized this course in 2010, with the total of 270 hours in the 6-year curriculum. In the first year (50 hours students learned basic principles of scientific method, structure of scientific article, basic statistical concepts, data analysis, interpretation and presentation. In the second year (25 hours students applied the knowledge from the first year in real examples of research data to answer a research hypothesis and present the results and conclusions. Students were guided through the process of making a hypothesis, analyzing data, interpreting them, constructing tables and figures, and writing a short research report. At the end of the course they formally presented the results to other students and course teachers, using PowerPoint slides. The third year (25 hours was devoted to mastering concepts and basic skills of evidencebased medicine (EBM. The course in the fourth year (25 hours was integrated with the clinical courses (internal medicine, neurology, and psychiatry and structured as a “journal club”. In the fifth year (25 hours, the teaching was devoted to developing a research plan for the graduation thesis that the students had to conduct during the sixth year. The sixth year (120 hours was devoted to the execution of research planned in the fifth year, including data collection, data analysis, interpretation, and thesis writing and defense. Conclusion. The new course succeeded in increasing students’ knowledge and skills for critical thinking and EBM, and prepared them for life-long learning in medicine.

    With the recent growth of fellowships in international emergency medicine, the authors sought to evaluate medical students' attitudes toward international emergency medicine and to determine the effects these attitudes have on their residency selection. Cross-sectional survey. An anonymous, eight-question online survey was distributed to all members of the American Academy of Emergency Medicine Resident and Student section. This survey was also distributed to fourth-year medical students rotating through the Emergency Department at Los Angeles County and the University of Southern California. Ninety-eight surveys were collected, 61 from rotating students and 37 from the AAEM mailing. There were no statistically significant differences in responses between the two groups. Of the respondents, 49.4% of have been exposed to IEM, and 46.9% have participated in international health projects. Ninety-four percent agree that IEM is an exciting career option. Seventy-nine percent said programs with IEM opportunities are more appealing than those without, and 45% said the presence of IEM opportunities would be an important factor in rank list; 53% believe that IEM requires formal public health training, and 63% believe it requires tropical medicine training; 68.3%of respondents speak a language in addition to English. This subset was more likely to have participated in IEM projects previously (p = 0.026) but not more likely to make match choices based on IEM. Half of medical students surveyed had prior experience in international health, and most agree that international emergency medicine is an exciting career option. Over two thirds believe that the presence of IEM opportunities will be a factor in their match list decision.

    Full Text Available Despite progress in the last four decades in terms of access to essential medicines, more than a third of the world population especially from the poorest countries have serious difficulties in accessing the medicines they need at an affordable price and with the right quality. Already in 1975 the 28th World Health Assembly discussed the need to set recommendations regarding selection and acquisition of medicines at reasonable prices and proven quality to meet national health needs. Consequently in 1977, the first WHO Model List of Essential Medicines was prepared by an expert committee. Since then, the list has been subjected to a series of updating and dissemination processes, together with discussion about the cost, patents and quality of medicines, as well as information on safety and effectiveness of each drug that is listed. The article addresses how this process has evolved from the beginning to present day.

    One hundred and seventeen cases of tuberculous disease who came to the Authors' observation in 10 years are described. Some cases are illustrated in details just to point out the complexity and the different guises of clinical presentation and to underscore the importance of an high index of suspicion for tuberculosis in patients who are admitted to a ward of internal medicine. In 71 patients with active, progressive tuberculous disease, the diagnosis was confirmed by bacteriological findings in 29 cases and by bioptical and hystological data in 5 cases; in the remaining 37 cases only clinical and radiological criteria were met but the diagnosis was confirmed by the improvement which was observed after antimycobacterial therapy. Many difficulties have been met in the differential diagnosis between pulmonary tuberculosis and bronchogenic carcinoma in those cases with anamnestic and radiological data of previous pulmonary tuberculosis. When the radiological site of lesions was in the posterior segments of the lung, tuberculosis was the most probable diagnosis, while bronchogenic carcinoma is most oftenly localized in the anterior segments; only in 5 cases of the Author's series the above mentioned criterion was not satisfied. In 46 cases with clinical signs of inactive tuberculous disease which had not been adequately treated with chemotherapy, isoniazid was given only to those patients with a high risk of reactivation (silicosis, diabetes, chronic alcholism, gastric resection, prolonged steroid therapy). Two cases of isoniazid hepatitis were observed among patients treated by the Authors.

    Peer-assisted learning (PAL) has become a well-accepted teaching method within medical education. However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective. To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors. A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80). The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants). The discussions were analyzed using content analysis. The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available. On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward. The tutor-student working alliance acts through its flat hierarchy. Nevertheless, tutors cannot represent an adequate substitute for experienced physicians.

    The issue of transition from student to practitioner of Chinese medicine (CM) in Australia and other Western countries has received little formal attention. Workforce studies, while not up to date nationally in Australia, suggest that the majority of CM practitioners practice as sole practitioners or in small practices. Data from the state of Victoria suggest that a significant proportion of the CM workforce is relatively new to the profession. It is not known how many graduates successfully enter the workforce and importantly, remain in it. An initial survey of final-year bachelor degree CM students in Australian education institutions in 2008 suggested that students felt "somewhat" prepared for clinical practice in eight dimensions of clinical practice. The authors conducted a follow-up study to this initial one, seeking to investigate perceptions of confidence in CM graduates in various aspects of clinical practice within the first year of completing their degree. A content-validated survey based on the previous study was distributed to a subset of 30 graduates from the original study cohort who had indicated a willingness to participate in this follow-up survey. There were a small number of responses (n=12), limiting the usefulness of the quantitative questions. However, some interesting qualitative outcomes from the long-answer part of the survey support findings from the previous study that recent practitioners would like more clinical experience, as well as support in developing their business and interpersonal skills, and the option to participate in a professional mentoring arrangement. Results of this study suggest that both education providers and professional associations may be able to play important and complementary roles in assisting CM students to successfully transition into the workforce. If CM is to continue to develop as a profession in Australia, it will be important that more attention be given to how to assist new graduates to successfully

    Full Text Available Cars not only function simply as a mean of transportation. Like paintings, the design of a car could represent a certain cultural and social phenomenon of a country. The design of Chevrolet (Chevy Corvette is very different compared to its competitors in the 50s. The size, engine, weight, and the materials of this car were chosen based on the assumption that speed and agility is on top of everything. It was not surprising that in the 50s, the year when the first Corvette was designed and launched, The US was involved in a cold war with the Soviets. Arm race and competition to be the first was the major issue and Corvette was the first car that suggests this spirit. This paper tries to show the distinctiveness of Corvette and how it can be used to explain the character of American people in the fifties

    ORGANISATION OF TEACHING INTERNAL MEDICINE: The Department for Internal Medicine and Internal Clinics were founded in spring 1922. Dr. Radenko Stankovic and Dr. Dimitrije Antic were appointed as part-time Professors, while Dr. Aleksandar Ignjatovski, a former Full-time Professor of the Warsaw University, was appointed as professor under contract. A year later, Dr. Aleksandar Radosavljevic was appointed as Part-time Professor. In the General State Hospital and Military Hospital, certain wards were turned into clinics. II and III Internal Clinics were situated in the barracks, while the Propedeutic and I Internal Clinics were located in the Military Hospital. Upon the construction of the buildings of the Internal Clinic and General State Hospital, the Propedeutic and I Internal Clinics were permanently placed in the new building, and II and III Internal Clinics in the General State Hospital. Teaching of Internal Medicine started 31 October 1922. Dr. R. Stanko vic delivered a lecture in Propedeutics for students of the fifth term. This date marks the beginning of teaching internal medicine at the newly established School of Medicine, University of Belgrade. Dr. A. Ignjatovski started lecturing Internal medicine 23 March 1923, whereas Dr. D. Antic and and Dr. A. Radosavljevic also delivered lectures in the areas of Internal Medicine within their professional scope. At the beginning, the clinics belonged to the General State Hospital. It was impossible to teach successfully in hospital, therefore upon the professors' request, the clinics were separated and thus became the institutions belonging to the School of Medicine-educational institutions, while hospitals were health institutions. The rule was 'one professor--one clinic'. After the Second World War, teaching Internal Medicine was begun in demolished buildings in very difficult financial circumstances. The Propedeutic Internal clinic was renamed IV Internal Clinic, which continued dealing predominantly with

    Sleep medicine remains an underrepresented medical specialty worldwide, with significant geographic disparities with regard to training, number of available sleep specialists, sleep laboratory or clinic infrastructures, and evidence-based clinical practices. The American Academy of Sleep Medicine (AASM) is committed to facilitating the education of sleep medicine professionals to ensure high-quality, evidence-based clinical care and improve access to sleep centers around the world, particularly in developing countries. In 2002, the AASM launched an annual 4-week training program called Mini-Fellowship for International Scholars, designed to support the establishment of sleep medicine in developing countries. The participating fellows were generally chosen from areas that lacked a clinical infrastructure in this specialty and provided with training in AASM Accredited sleep centers. This manuscript presents an overview of the program, summarizes the outcomes, successes, and lessons learned during the first 12 years, and describes a set of programmatic changes for the near-future, as assembled and proposed by the AASM Education Committee and recently approved by the AASM Board of Directors.

    Full Text Available Chile is uniquely situated to be a leader in South American development of the specialty of Emergency Medicine. Chilean emergency medicine has successfully transitioned from a novelty training idea to a nationally and internationally recognized entity with serious public health goals. There are more residency training programs in Chile than in any other South American or Latin American country, and the specialty is formally recognized by the Ministry of Health. Chilean emergency medicine thought leaders have networked internationally with multiple groups, intelligently used outside resources, and created durable academic relationships. While focusing on locally important issues and patient care they have successfully advanced their agenda. Despite this, the specialty faces many new challenges and remains fragile but sustainable. Policy makers and the Chilean MOH need to be acutely aware of this fragility to preserve the progress achieved so far, and support ongoing maturation of the specialty of Emergency Medicine.

    In the long sweep of meteorological history - from Aristotle's Meteorologica to the threshold of the third millennium - the 1950s will surely be recognized as a defining decade. The contributions of many individuals were responsible for the combination of vision and institution building that marked this decade and set the stage for explosive development during the subsequent forty years. In the minds of many individuals who were active during those early years, however, one name stands out as a prime mover par excellence: Lloyd Viel Berkner. On May 1, 1957, Berkner addressed the National Press Club. The address was entitled, "Horizons of Meteorology". It reveals Berkner's insights into meteorology from his position as Chairman of the Committee on Meteorology of the National Academy of Sciences, soon to release the path-breaking report, Research and Education in Meteorology (1958). The address also reflects the viewpoint of an individual deeply involved in the International Geophysical Year (IGY). It is an important footnote to meteorological history. We welcome this opportunity to profile Berkner and to discuss "Horizons of Meteorology" in light of meteorology's state-of-affairs in the 1950s and the possible relevance to Berkner's ideas to contemporary issues.

    The medical curriculum at King's College London School of Medicine is a 5 year course; an extended program (6 years) and a graduate entry program (4 years) are also available. The first 2 years of the curriculum comprise phases 1 and 2. The curriculum consists of core material that is common to all students and student-selected components (students undertake three such components in the first 2 years). Phase 1 lasts 12 weeks and students learn the principles of tissue and organ structure and function. They are also introduced to the practice of medicine (concepts of health, communication, ethics, inter-professional education and medicine in the community). Phase 2 consists of 36 weekly clinical scenarios that place basic medical science in a clinical context. Phase 2 covers cardiovascular, respiratory, gastrointestinal, renal and musculoskeletal systems; nutrition; endocrinology; head and neck anatomy; neuroscience; genetics; and infections. Teaching continues in pri! mary care and in the hospitals and includes basic and advanced life support. Learning experiences include lectures, tutorials, practical classes, dissection and prosection, communication skills, e-learning, student-led sessions and primary care and hospital visits. Assessment consists of in-course assessment (e.g., presentations, tests and essays) and end-of-year examinations which consist of written papers and an objective structured clinical examination at the end of year 2. The main strengths of the program include the scenario format of learning and the practice of medicine early on. The difficulties arise mainly from the large numbers of students (420 per year).

    In 1986, APLMS was established to promote the various activities of Laser Medicine Surgery in the Asia-pacific regions. The purpose of APLMS is not only to deliver academic information but also technological, industrial and social ones. Until now, the 9 congresses had been taken place in the different countries in Asia-Pacific regions. As the results of the 18years" efforts, the organizations of each country on laser medicine and surgery have been established, and the network of researchers and clinicians has been completed. The next challenges are proposed such as education, training, and standardization of methods. To establish guidelines and regulation for laser medicine and surgery, and to transfer technology are also important issues.

    In 2008, the 50th anniversary of ASCH, hypnosis is used increasingly for healthcare applications in hospitals, clinics, and psychotherapy practice. A substantial body of research demonstrates the efficacy of hypnosis as part of the integrative treatment of many conditions that traditional medicine has found difficult to treat (e.g., Pinnell & Covino, 2000; Elkins, Jensen, & Patterson, 2007). The practice of hypnosis in healthcare has been altered and centrally influenced by the rapid growth of technological medicine in the 1950's, the AIDS epidemic and development of psychoneuroimmunology, revolutionary developments in genetics and neuroimaging technology, and the progression from alternative to integrative medicine. We have come to develop more detailed expectations about the beneficial effects of hypnotic interventions for health problems. We have also come to know that in these populations hypnosis can lead not only to reduced anxiety but also specifically altered physiological parameters.

    To investigate the research status of emergency medicine in China through literature search of international emergency medicine journals and retrospectively compare the outputs of emergency medicine articles of the 3 major regions of China-Mainland (ML), Taiwan (TW), and Hong Kong (HK). Emergency medicine journals were selected category from Science Citation Index Expand. Articles from the ML, TW, and HK were retrieved from PubMed database. The total number of articles, publication types, research contents, impact factors (IF), and articles published in each journal were conducted for quantity and quality comparisons. A total of 1760 articles from 19 emergency medicine journals were searched, of which 395 were from ML, 1210 from TW, and 155 from HK. Accumulated IF of articles from TW (2451.109) was much higher than that of ML (851.832) and HK (328.579), whereas the average IF of articles from TW (2.02) was the lowest. The number of case reports was the highest, which was, 69 from ML, 637 from TW, and 25 from HK, respectively. Although emergency medicine was involved with multiple organs and multiple systems, the reports of trauma accounted for 25% of the research contents. The total number of articles from both China and the rest of the world increased significantly from 2000 to 2014, especially ML. The total number of articles from TW was still much more than that of ML and HK, whereas the quality of articles from TW was not as good as ML and HK. Case report had the highest share of publication types, whereas the proportions of meta-analysis and observational study were the lowest. As for research contents, the proportion of trauma was still the highest. Copyright © 2015 Elsevier Inc. All rights reserved.

    Medical schools have begun to incorporate self-reflection exercises into their curricula, with the belief that these exercises help students master the material more deeply and perform better. Reflection may be a potential learning tool for emergency medicine (EM), but there are few data supporting this hypothesis. The authors evaluated the relationship between a linguistic marker of the degree of reflection after a student's shift in an emergency department and that student's clerkship performance. The authors conducted a retrospective case series by analyzing the performance and reflective statements of 116 students from a single medical school who participated in a required EM clerkship at one or two of four clinical sites from 2013-14. After each shift, an attending emergency physician evaluated the student according to the RIME (Reporter-Interpreter-Manager-Educator) scheme. The authors developed software to extract the text from those comments, remove uninformative words and standardize the remaining words. The authors determined the most common words and two-word phrases that students used to describe their shift. The correlation between students' final clerkship grades and the fraction of student comments with at least one content word was analyzed. Of the 145 possible students, 116 were included for analysis. The other 29 were excluded as they were visiting students who did not receive a final numeric grade. The correlation between final grade and the number of completed self-reflections was 0.32. The correlation between final grade and the average number of words in each self-reflection was 0.21. The first correlation is significantly greater than 0 (p=0.03, t-test), but the second correlation is not (p=0.16, t-test). The median final grade of those who wrote reflections on more than half of their shifts was significantly greater than those who wrote reflections half of the time, 83.675 versus 79.23 (p=0.05, 2-sample Kolmogorov-Smirnov test).

    We investigated scientific publications in laboratory medicine originating from mainland China, Hong Kong and Taiwan over the past 10 years. The information about articles published in the included journals were determined by computer-searching on PubMed and data were extracted independently and analyzed in relation to the number of articles. From 2000 to 2009 there were 1166 articles published in laboratory medicine journals from the major Chinese regions (mainland China, Hong Kong and Taiwan). This exceeded Japan, Germany, the United Kingdom and France from 2005 onwards. Also, the number of articles from mainland China exceeded those from Hong Kong and Taiwan from 2004 onwards. The average impact factor (IF) from Hong Kong ranked the first, followed by mainland China, and then Taiwan. Clinica Chimica Acta seems to be the most popular laboratory medicine journal among Chinese authors. Over the past 10 years, Chinese authors have been more and more active in the field of laboratory medicine. Mainland China seems to have caught up to Hong Kong and Taiwan regarding publication of papers in this field. Copyright 2010 Elsevier B.V. All rights reserved.

    On March 21, 1973, Israel's Council of Higher Education (CHE) was convened by Yigal Alon, the Council's chair and the Minister of Education, to vote on whether to approve a proposal to establish a school of medicine in the Negev. In the preliminary discussion, Avraham Harman, the president of the Hebrew University in Jerusalem turned to Professor Moshe Prywes, the president of Ben-Gurion University in the Negev and commented: "Be assured, a school of medicine in Beer Sheva won't pass." At the close of the discussion, the twenty members of the CHE were asked to vote. The vote was a tie - 8 in favor, 8 against and 3 refrained. According to the CHE charter, the chairperson was required to break the tie. The minister - Yigal Alon, raised his hand in favor. Thus, by a bare voice, it was decided to establish a medical school in the Negev. This paper describes the processes that culminated in the approval of a school of medicine by the Council of Higher Education in March 1973. It presents the various personalities, agents, bodies and institutions that played a role in this process and their relative weights in the ultimate decision to establish a school of medicine in the Negev.

    Cardiovascular diseases stem from modifiable risk factors. Peer support is a proven strategy for many chronic illnesses. Randomized trials assessing the efficacy of this strategy for global cardiovascular risk factor modification are lacking. This study assessed the hypothesis that a peer group strategy would help improve healthy behaviors in individuals with cardiovascular risk factors. A total of 543 adults 25 to 50 years of age with at least 1 risk factor were recruited; risk factors included hypertension (20%), overweight (82%), smoking (31%), and physical inactivity (81%). Subjects were randomized 1:1 to a peer group-based intervention group (IG) or a self-management control group (CG) for 12 months. Peer-elected leaders moderated monthly meetings involving role-play, brainstorming, and activities to address emotions, diet, and exercise. The primary outcome was mean change in a composite score related to blood pressure, exercise, weight, alimentation, and tobacco (Fuster-BEWAT score, 0 to 15). Multilevel models with municipality as a cluster variable were applied to assess differences between groups. Participants' mean age was 42 ± 6 years, 71% were female, and they had a mean baseline Fuster-BEWAT score of 8.42 ± 2.35. After 1 year, the mean scores were significantly higher in the IG (n = 277) than in the CG (n = 266) (IG mean score: 8.84; 95% confidence interval (CI): 8.37 to 9.32; CG mean score: 8.17; 95% CI: 7.55 to 8.79; p = 0.02). The increase in the overall score was significantly larger in the IG compared with the CG (difference: 0.75; 95% CI: 0.32 to 1.18; p = 0.02). The mean improvement in the individual components was uniformly greater in the IG, with a significant difference for the tobacco component. The peer group intervention had beneficial effects on cardiovascular risk factors, with significant improvements in the overall score and specifically on tobacco cessation. A follow-up assessment will be performed 1 year after the final assessment

    Most medical schools require formal competence assessment of students immediately prior to graduation, but variation exists in the approach to endpoint assessments. This article reports perceptions of senior students and graduates from a school with a six-year program which has introduced final year workplace immersion placements following a barrier examination at the end of the penultimate Year 5. Final year students (22) and recent graduates (4) attended focus groups and in-depth interviews exploring their perceptions of the value of the curriculum experience during the final two years, the structure and timing of assessment, and their preparation for internship. Participants felt that the penultimate year was more pressured, and focused on passing "artificial" examinations. In contrast, the final year was more relaxed, building skills for postgraduate work and later career development. As a result, students felt well prepared for internship with some indication that the self-directed nature of the final year promoted a lifelong learning approach. The final year workplace immersion model was regarded positively by senior students of this medical school. This model may be a better way of preparing students to be junior doctors than a traditional final year heavy on theoretical learning and assessment.

    The paper gives a short presentation of 40 years of experience of Osijek Health Center family physicians in colorectal cancer (CRC) prevention and early detection. Systematic work in the prevention and early detection of cancer includes raising public awareness and knowledge of healthcare issues, educating health professionals, conducting scientific research and contributing to the development and implementation of the National Program for Early Detection of Cancer. Cooperation of the Ministry of Health and Osijek Health Center resulted in issuing brochures entitled Men and Cancer and Women and Cancer in 100,000 copies, and later 20,000 copies of a book entitled Smoking Induced Diseases. Analysis of patients undergoing surgery for CRC at Department of Surgery, Osijek General Hospital during the 1973-1984 period showed a low 5-year and 10-year survival rate. A study of early CRC detection by using fecal occult blood test (FOBT), conducted in Osijek between 1980 and 1984, included 11,431 subjects. Results of the study confirmed FOBT to be an acceptable and reliable method for early CRC detection because of its simple use, general level of acceptance by the population and relatively low cost. Physical examinations aimed at detecting CRC by using FOBT were to be implemented in a planned, systematic manner in high-risk persons (those older than 50). Based on the results of this study, guidelines on cancer control were published in 1993 by teams of primary care physicians, especially family physicians. The Osijek Health Center, specifically its Family Medicine Department, participated in the development and implementation of the National Program for Colorectal Cancer Prevention and Early Detection, which started in 2007. Response to the National Program for Early Detection of Colorectal Cancer in individual counties was under 37%. A project called Early Cancer Detection Model Integrated in Family Medicine Practice, which was implemented in Osijek and included subjects

    Indian system of medicine has its origin in India. The system is currently renamed as AYUSH, an acronym for Ayurveda, Yoga & Naturopathy, Unani, Sidha and Homeopathy. These are the six Indian systems of medicine prevalent and practiced in India and in few neighboring Asian countries. The primary objective of this review was to gain insight in to the prior and existing initiatives which would enable reflection and assist in the identification of future change. A review was carried out based on the five year plan documents, obtained from the planning commission web portal of Govt. of India, on medical education, research and development of AYUSH systems of medicine. Post independence, the process of five year planning took its birth with the initiation of long term planning in India. The planning process embraced all the social and technology sectors in it. Since the beginning of five year planning, health and family welfare planning became imperative as a social sector planning. Planning regarding Indian Systems of Medicine became a part of health and family welfare planning since then. During the entire planning process a progressive path of development could be observed as per this evaluation. A relatively sluggish process of development was observed up to seventh plan however post eighth plan the growth took its pace. Eighth plan onwards several innovative development processes could be noticed. Despite the relative developments and growth of Indian systems of medicine these systems have to face lot of criticism and appraisal owing to their various characteristic features. In the beginning the system thrived with great degree of uncertainty, as described in 1(st) five year plan, however progressed ahead with a vision to be a globally accepted system, as envisaged in 11(th) five year plan. A very strong optimistic approach in spreading India's own medical heritage is the need of the hour. The efforts are neither completely insufficient nor sufficient enough; hence

    Replantation of amputated fingertip is a technical challenge to the microsurgeons. The success rate depends directly on the availability and the size of preserved vessels and on the degree of their damage. In distal digital amputations, veins are usually not easily recovered or even absent, and thus high number of replantation procedures fails because of the venous congestion. The use of medicinal leeches is a treatment option for venous congestion of replanted fingers. A case report of a 4-year-old patient after fingertip replantation without venous anastomosis when temporary venous drainage was provided by an application of medicinal leeches is reported together with literature review. We observed an unusually short duration of venous congestion (48 hours) and there was no need of blood transfusion.

    Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine. To this end, the committee formulated the objectives, content, evaluation system, and pedagogical methods to be used in those courses. The 25 self-teaching modules, together with the observation and practical interpretation of radiology sessions, proved highly useful in solving the initial problems, and were of particular interest to the students.

    This paper examines the traditional use of medicinal plants in Northern Peru, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin. Northern Peru represents the center of the old Central Andean "Health Axis," stretching from Ecuador to Bolivia. The roots of traditional healing practices in this region go at least as far back as the Moche period (AC 100-800). Although about 50% of the plants in use reported in the colonial period have disappeared from the popular pharmacopoeia, the plant knowledge of the population is much more extensive than in other parts of the Andean region. 510 plant species used for medicinal purposes were collected, identified and their vernacular names, traditional uses and applications recorded. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had twelve species, and Apiaceae and Poaceae 11 species. The highest number of species was used for the treatment of "magical/ritual" ailments (207 species), followed by respiratory disorders (95), problems of the urinary tract (85), infections of female organs (66), liver ailments (61), inflammations (59), stomach problems (51) and rheumatism (45). Most of the plants used (83%) were native to Peru. Fresh plants, often collected wild, were used in two thirds of all cases, and the most common applications included the ingestion of herb decoctions or the application of plant material as poultices.

    States are seeking ways to retain primary care physicians trained within their borders. We analyzed the 5-year retention and rural Iowa location decisions for 1,645 graduates of the Iowa Family Medicine Training Network (IFMTN)-eight residency programs (in seven different cities) that are affiliated with the Carver College of Medicine (University of Iowa). Data from 1977-2014 includes 98.5% of active graduates. Location in Iowa 5 years after graduation was the dependent variable in a binary logistic regression. A second model used rural location in Iowa as the dependent variable. Independent variables included graduation year cohort, IMG status, sex, undergraduate medical training in Iowa, medical degree, and residency location. Undergraduate medical training in Iowa was strongly related to retention. Compared to graduates of the AMC residency, graduates of six of the seven community-based programs were significantly more likely to be practicing in Iowa. While the overall proportion of graduates practicing in rural Iowa was high (47.3%), women and IMGs were significantly less likely to practice in rural areas. Graduates of the Mason City program were significantly more likely to practice in a rural area after graduation. The experience of the IFMTN suggests that educating family physicians in community-based programs contributes significantly to in-state retention even 5 years after graduation. While all programs contribute to the rural FM workforce in Iowa, the residency program located in a rural community (Mason City) has a disproportionately positive impact.

    Many high-reliability organizations in industries outside of health care have sustained high levels of excellence and prevention of harm while managing complex systems and risk. To date, no health care organizations has organized its efforts to achieve highly reliable results despite several decades of improvement science. Laboratorians were early adopters of quality initiatives and process improvements. In the late 1990s, the Division of Pathology and Laboratory Medicine at The University of Texas MD Anderson Cancer Center embarked on a major effort to improve quality and patient safety and to reduce waste. This article describes the institution's journey toward approaching high reliability with the intent to share not only the tools and best practices, but also the ongoing reassessment of the problems detected on the journey. The authors hope that their experience will help the reader develop interventions to adapt in their own environment to facilitate more optimal patient care.

    To establish the prevalence of congenital malformations diagnosed in Maternal-Fetal Medicine Unit of Hospital de San José, Bogotá-Colombia and comparing them to national and international reports. Retrospective, descriptive observational where the quantification of all malformed fetuses diagnosed in Maternal-Fetal Medicine Unit from June 2010 to June 2013 was performed. 236 malformed fetuses, a total of 11,914 births, for a prevalence of 1.98% were included at a mean gestational age at diagnosis of 26.7 weeks (SD 7.1 weeks). The most common congenital malformations were at the level of Central Nervous System (CNS) 88 (37%) in total and within them, the most prevalent was ventriculomegaly 16 (7%). Of the 236 malformed fetuses, 165 fetuses (70.2%) had only one affected system 29 (12.3%) 2 compromised systems and 42 (17.5%) over 3 affected systems. Karyotyping was offered to all antenatal patients, however, accepted only 63 (26.7%), and 39 (62%) with normal results and the other aneuploidies were found, having Trisomy 21 as the most common. It was possible to establish a concordance of 86% between the antenatal and postnatal diagnosis. The perinatal mortality found in this study was 34.7%, mainly in fetuses with congenital diaphragmatic hernia 16 cases (88.8%), fetal non-immune hydrops 8 cases (80%), cardiovascular abnormalities 31 cases (46.2%) genitourinary and 13 cases (24%), and fetuses with CNS malformations such as sequence acranea-anencefalia, holoprosencephaly and encephalocele mortality occurred in 100%. In this study the prevalence of congenital anomalies was found comparable to that reported at local and global levels, which were diagnosed and adequately characterized by more than two-thirds by obstetrical ultrasound performed by trained personnel in prenatal diagnosis. Perinatal morbidity and mortality remain high thoracic, cardiovascular, renal and non-immune hydrops congenital anomalies.

    Full Text Available Introduction: During the medical internship year, students attend several hospitals and are observed and influenced by postgraduate students, general practitioners and other interns, who provide them with fundamental support regarding professional training. Bullying is defined as an aggressive behavior that occurs between a perpetrator and a victim in different scenarios and authority relationships, such as clinical practices at Medicine programs. Objective: To describe the perceived frequency of bullying among a group of interns of the Faculty of Medicine from Universidad Nacional de Colombia during internship. Materials and methods: A transversal analytical study was performed through a questionnaire applied to 82 medical interns of the School of Medicine from Universidad Nacional de Colombia. Results: The perceived frequency of bullying was 90%. Statistically significant differences were not found in the stratified analysis by sex or place of practice. In most cases, bullying was perpetrated by other interns, while residents and specialists showed a lower frequency. Conclusion: Perceived frequency of bullying was higher than expected according to the existing literature. These results can be used as a basis for new studies.

    To resolve the problem that evidence-based medicine (EBM) courses are not sufficiently taught in Japanese medical schools, we organized a year-round EBM-learning course. This study was an observational study and was designed to evaluate the participants' understanding of EBM using an original survey. The survey was given three times. In total, 18 students responded to our survey. Of those 18 students, six students answered both the first and the last surveys, and their mean score increased 1.17 of 4.00 (95% CI: 0.72-1.65). These results suggest our course improved students' ability to read clinical articles.

    Implementing the National Health Program assumed in Poland for the years 2007 2015, family doctors in their everyday work try to contribute to reducing the popularity of tobacco smoking as well as reducing and changing the structure of alcohol consumption, whose aim is to reduce the negative health effects caused by those substances [9]. Non smoking personnel and prohibition of smoking in health care centres are the basis for effective anti-tobacco counsel. The same dependence occurs in the case of alcohol abuse. The aim of the work was to evaluate the knowledge of the effects of alcohol abuse among students of the 6th year of the Faculty of Medicine of UMB (Medical University of Białystok), as well as to analyze the structure of drinking and smoking among the prospective doctors. The study material was collected by means of anonymous surveys carried out before classes belonging to the family medicine subject block. The obtained data showed that the students had only superficial knowledge of the negative health effects of alcohol abuse and tobacco smoking. 26% of female students and 12% of male students smoke regularly. The results of the shortened Alcohol Use Disorders Identification Test (AUDIT), so-called AUDIT-C, showed that 50% of prospective female doctors and 61.1% of prospective male doctors drink alcohol in a risky way.

    Full Text Available Background: Smoking is one of leading various diseases and even death globally. It is often difficult for smokers to stop smoking, even those who work as a medical professional because there are some barriers around them. The objective of this study was to get an overview of the barriers to smoking cessation among smoker students of Faculty of Medicine, Universitas Padjadjaran. Methods: A descriptive study was carried out to 62 medical students 2012–2013 academic year in the Faculty of Medicine, Universitas Padjadjaran. Before the respondents were selected, a survey using questionnaire was conducted to all medical students from the same academic year to determine their smoking status. A set of questions was developed, consisted of 4 components: physical or social, psychological or emotional, accessibility, and social contextual/life circumstances barriers to smoking cessation. The collected data were analyzed and presented in the form of percentages shown in the tables and figures. Results: The most frequent barriers were from physical or social barriers (friends who smoke, 85%, psychological or emotional barriers (fear of losing enjoyment, 71%, barrier to access (lack of information about the way of smoking cessation, 42% and social contextual/life circumstances barriers (having other priorities other than to stop smoking, 71%. Conclusions: There are some barriers in medical students smokers make them difficult to stop smoking although they have more knowledge about health and the impact of smoking on health than other people.

    Advocacy is often described as a pillar of the medical profession. However, the impact of advocacy training on medical students' identity as advocates in the medical profession is not well-described. We sought to introduce an advocacy curriculum to a mandatory Health Care Disparities (HCD) course for 88 first year medical students. The 2013 HCD added advocacy curriculum that included: guest lecturers' perspectives on their advocacy experience; reflective essay assignments assessing self-identify as an advocate; advocacy-specific lectures and large group discussions; and participation in small group community projects. A mixed methods approached was used to evaluate 88 first year medical students' advocacy themed reflective essays, independently coded by three investigators, and Likert-response questions were compared to published benchmarked items. The IRB exempted this study. Analysis of student essays revealed that students were better able to identify as an advocate in medicine. The survey also revealed that 86% post-course vs. 73% precourse agreed/strongly agreed with the statement: "I consider myself an advocate" (p=0.006). Exposing all medical students to advocacy within medicine may help shape and define their perceived professional role. Future work will explore adding advocacy and leadership skill training to the HCD course.

  10. [What is death?--Definitions and diagnoses from 2500 years of natural philosophy and medicine].

    Schäfer, D

    2013-12-01

    For very long medicine has been dealing with the question what death means and when it has occurred. The promotion of this debate is mainly owed to the new medical findings and the concrete requirements of the clinical practice; but other factors like social-historical influences (in particular the dispute over the secure determination of death) as well as the (de-)medicalization of the concept of death have also to be taken into account. In a concise historical overlook this study aims to demonstrate the development of the definition of death: In ancient Greece Aristotle, disregarding the transcendent teleology, describes the natural or non-natural death that occurs when the production of the vegetative warmth in the central organ - the heart - has ceased. In the Enlightenment Johann August Unzer (emulated later by Bichat and Hufeland) worked out the concept of the step-by-step process of death: In the attempt to explain sudden death, apparent death and reanimation the enlightened physiologist differentiated between the cessation of the senses (caused by heart death and brain death) and the vegetative functions. In the second half of the 20th century progress made in transplanting and intensive care generated a broadened medical definition of death that met strong opposition in the discussions on the autonomy of the patient and the worth of human life. Generally considered, the increasing differences in interpreting death between physicians and medical laymen, but also in medical practice and basic research are mainly due to the divergent demands regarding the definition and diagnosis of death. © Georg Thieme Verlag KG Stuttgart · New York.

    To describe the creation and evaluate the use of a wiki by medical residents, and to determine if a wiki would be a useful tool for improving the experience, efficiency, and education of housestaff. In 2008, a team of medical residents built a wiki containing institutional knowledge and reference information using Microsoft SharePoint. We tracked visit data for 3 years, and performed an audit of page views and updates in the second year. We evaluated the attitudes of medical residents toward the wiki using a survey. Users accessed the wiki 23,218, 35,094, and 40,545 times in each of three successive academic years from 2008 to 2011. In the year two audit, 85 users made a total of 1082 updates to 176 pages and of these, 91 were new page creations by 17 users. Forty-eight percent of residents edited a page. All housestaff felt the wiki improved their ability to complete tasks, and 90%, 89%, and 57% reported that the wiki improved their experience, efficiency, and education, respectively, when surveyed in academic year 2009-2010. A wiki is a useful and popular tool for organizing administrative and educational content for residents. Housestaff felt strongly that the wiki improved their workflow, but a smaller educational impact was observed. Nearly half of the housestaff edited the wiki, suggesting broad buy-in among the residents. A wiki is a feasible and useful tool for improving information retrieval for house officers.

    The intraosseous puncture (IO) is a fast and safe alternative to the puncture of peripheral veins in emergency situations in children < or =6 years of age. The purpose of this paper is to summarize 10 years of experience on the prehospital use of the IO method by the Helicopter Emergency Medical Service (HEMS) "Christoph 22", Ulm. This was a retrospective study from 1 January 1996 to 31 December 2005. Out of a total of 9,549 missions, the proportion of children was 11.1%. In 27 children (4.2% of the children < or =6 years of age) an IO puncture was performed. Patients of the IO group were younger (1.0 vs. 3.7 years of age; p<0.001) and showed a higher degree of injury severity (NACA 6 vs. 4; p<0.001) compared to the total children group. In all children of the IO group (100%), the intraosseous puncture was the method of first choice to obtain access to the vascular system by the HEMS team. In 96.4% of these cases (26/27), the first IO puncture attempt was successful - in one child, a second puncture attempt was necessary. A standardized puncture technique was performed using the proximal tibia. The time required for successful placement of the IO infusion line was 60 s or less in all cases. In 37% of the cases (10/27) the IO infusion line was used for induction of general anaesthesia; dosage and onset of administered drugs were described as being equivalent to a peripheral infusion line. In all cases, the IO needle was replaced in-hospital within 2 h by a central or peripheral iv line. No complications were observed. The IO infusion technique is a simple, fast and safe alternative method for emergency access to the vascular system in children < or =6 years of age in the prehospital setting.

    People of Chinese ethnicity are the largest population in the world. Critical care medicine in China is developing rapidly and has achieved great advances in recent 20 years. The research contribution in critical care medicine among Chinese individuals in the three major regions of China--Mainland (ML), Hong Kong (HK), and Taiwan (TW)--is unknown. Articles published in 18 journals on critical care medicine originating from ML, TW, and HK from 1999 to 2008 were retrieved from the PubMed database and Science Citation Index Expanded. Quantity and quality analyses were conducted for the total numbers of articles, clinical trials, randomized controlled trials, impact factors (IF), citations, and articles published in high-impact journals. There were 932 articles from ML (268), TW (506), and HK (158) from 1999 to 2008. The annual total numbers of articles of the three regions increased gradually from 1999 to 2008 (from 57 to 157). From 2002 onward, the number of articles published from ML exceeded that from HK, but TW still has the dominance in both annual and total number of articles published compared with ML and HK. The accumulated IF of articles from TW (1676.67) was higher than that from ML (708.25) and HK (449.51). TW had the highest average IF of 3.31 followed by HK of 2.85 and ML of 2.64. HK had the highest average citations of each article of 10.73, followed by TW of 6.74 and ML of 5.34. The Journal of Trauma was the most popular journal in the three regions. The total numbers of articles in China increased markedly from 1999 to 2008. TW published the most number of articles, clinical trials, and randomised controlled trials among the three regions. The Journal of Trauma was the most popular journal in the three regions.

    For academic research outcomes, an important bibliometric scoring termed as the journal impact factor (JIF) is used when assessment of the quality of research is required. No known study has been conducted to explore the bibliographical trends of 'Medicine, General & Internal' journals indexed by the annual Journal Citation Reports. Data from the Journal Citation Reports and Web of Science database were extracted to formulate a comprehensive analysis. In this study, the trends of 15 journals (5 top ranked and 10 low ranked; 5 English and 5 non-English based) were selected and analysed over a 9-year period (starting from year 1999 to 2007). Using the year 1999 as the base year, the results showed that the JIF rose significantly for the selected top ranked journals (up to 180.9%) while the low ranked ones slipped in their JIF value (down to -44.4%). The observed upward or downward trend was caused by a combination of other bibliographical measures like citations, number of citable, and total items published. It is postulated that changes in bibliographical trends can be classified as editorial and non-editorial influences. The impacts of these influences on the 15 selected journals over the 9-year period were also discussed retrospectively.

    The quantity and quality of publications in critical care medicine from East Asia haven't been reported. This study aimed to investigate the contribution of publications from East Asia. Articles from China, Japan and South Korea in 2005 to 2014 were retrieved from Web of Science and Pubmed. The number of publications, impact factor, citation, and article types were analyzed. There were 3076 publications from East Asia (1720 from China, 913 from Japan, and 443 from South Korea). There were a significant decrease in publications from Japan (p = 0.024) and significant increases from China (p = 0.000) and South Korea (p = 0.009). From 2006, the number of articles from China exceed Japan. China had the highest total impact factor (6618.48) and citation (18416), followed by Japan (4566.03; 15440) and South Korea (1998.19; 5599). Japan had the highest mean impact factor (5.00) and citations (16.91), followed by South Korea (4.51; 12.64) and China (3.85; 10.71). China and South Korea`s contributions to critical care medicine had significant increases during the past 10 years, while Japan had a significant decrease. China was the most productive region in East Asia since 2006. Japan had the highest quality research output.

    It is widely recognized that burnout is prevalent in medical culture and begins early in training. Studies show pediatricians and pediatric trainees experience burnout rates comparable to other specialties. Newly developed Accreditation Council for Graduate Medical Education (ACGME) core competencies in professionalism and personal development recognize the unacceptably high resident burnout rates and present an important opportunity for programs to improve residents experience throughout training. These competencies encourage healthy lifestyle practices and cultivation of self-awareness, self-regulation, empathy, mindfulness, and compassion—a paradigm shift from traditional medical training underpinned by a culture of unrealistic endurance and self-sacrifice. To date, few successful and sustainable programs in resident burnout prevention and wellness promotion have been described. The University of Arizona Center for Integrative Medicine Pediatric Integrative Medicine in Residency (PIMR) curriculum, developed in 2011, was designed in part to help pediatric programs meet new resident wellbeing requirements. The purpose of this paper is to detail levels of lifestyle behaviors, burnout, and wellbeing for the PIMR program’s first-year residents ( N = 203), and to examine the impact of lifestyle behaviors on burnout and wellbeing. The potential of the PIMR to provide interventions addressing gaps in lifestyle behaviors with recognized association to burnout is discussed.

    Customer satisfaction is a key quality indicator of laboratory service. Patients and physicians are the ultimate customers in medical laboratory, and their opinions are essential components in developing a customer-oriented laboratory. A longitudinal investigation of customer satisfaction was conducted through questionnaires. We designed two different questionnaires and selected 1200 customers (600 outpatients and 600 physicians) to assess customer satisfaction every other year from 2012 to 2016. Items with scores satisfaction in 2014 was better, which illustrated our strategy was effective. However, some items remained to be less than 4, so we repeated the survey after modifying questionnaires in 2016. However, the general satisfaction points of the physicians and patients reduced in 2016, which reminded us of some influential factors we had neglected. By using dynamic survey of satisfaction, we can continuously find deficiencies in our laboratory services and take suitable corrective actions, thereby improving our service quality.

    The use of complementary and alternative medicine (CAM) is widespread in children with cancer and is poorly regulated. Case report. We describe a case of severe cyanide poisoning arising from CAM use. A severely agitated, encephalopathic, unresponsive 4-year-old boy (initial Glasgow Coma Scale of 3) with a history of metastatic ependymoma was brought to our emergency department by ambulance services. Initial blood gas analysis demonstrated severe metabolic/lactic acidosis. On detailed questioning of the parents, the use of CAM including intravenous and oral "vitamin B 17" (amygdalin) and oral apricot kernel was reported. After administering sodium thiosulfate, rapid improvement in his medical condition with complete recovery without need for further intensive care treatment was seen. Serum cyanide level was markedly elevated. Cyanide poisoning can be the cause of severe encephalopathy in children receiving CAM treatment with substances containing cyanogenic glycosides.

All invasive prenatal diagnosis procedures performed from 2003 up until 2010 (amniocentesis, chorionic villous sampling and fetal blood sampling) were analyzed. A total of 1560 invasive prenatal diagnostic procedures were performed during the 8 year period. Advanced maternal age is the leading indication for invasive prenatal diagnostic procedures followed by fetal abnormalities. The fetal loss rate was 0.2% for amniocentesis and 1.2% for CVS. Advanced maternal age is the leading indication for invasive prenatal diagnostic procedures at this centre but is on a declining trend. The fetal loss rates are comparable to auditable standards set by professional bodies, in this case, the Royal College of Obstetricians & Gynecologists of London.

    Full Text Available Abstract Background Medicines are commonly accessed and used for management of illness in children without a prescription. This potentially increases the risk of unwanted treatment outcomes. We investigated medicine use practices in management of symptoms of acute upper respiratory tract infections among children (≤12 years in households in Nakawa division, Kampala city. Methods This was a cross-sectional study conducted among 390 randomly selected children. Data on use of medicines in children (≤12 years during recent episode of acute upper respiratory tract infection was collected from their care takers using an interviewer administered questionnaire. A recall period of two weeks (14 days was used in during data collection. Results The prevalence of giving children non-prescription antimicrobial medicines was 44.8% (38.3-52.2. The most common disease symptoms that the children reportedly had included flu, 84.9% (331/390, cough, 83.1% (324/390, and undefined fever, 69.7% (272/390. Medicines commonly given to children included, paracetamol 53.1% (207/390, Coartem 29.7% (116/390, cough linctus 20.8% (81/390, amoxicillin 18.9% (74/390, Co-trimoxazole 18.5% (72/390, and diphenhydramine 15.4% (60/390. The major sources of medicines given to the children was hospital/clinic, 57.26% (223/390. Most of the children, 81% were given more than one medicine at a time. The majority, 62.3% (243/390 of the care takers who gave the children medicine during the recent illness were not aware of any medicine (s that should not be given to children. The predictors of non-prescription use of antimicrobial medicines in managing symptoms of acute upper respiratory tract infections in children included, medicines obtained from drug shop (PR: 1.45, CI: 1.14-1.85, medicines at home (PR: 1.8, CI: 0.83-1.198 and type of medicine (antimalarial (PR: 2.8, CI: 1.17-6.68.

    Full Text Available Most low-income nations have national medicine policy that emphasized the use of generic medicines in the public health sector. However, the use of generics is often debatable as there are concerns over its efficacy, quality, and safety compared to their branded counterparts. This study was conducted to compare the knowledge and perception of generic medicines among final year undergraduate medical, pharmacy, and nursing students in Sierra Leone. We conducted a questionnaire-based cross-sectional study among these students at the College of Medicine and Allied Health Sciences University of Sierra Leone. Out of the 62 students, only two (2/62, 3.2% knew about the acceptable bioequivalence limit. At least half of respondents in all three groups agreed that all generics are therapeutically equivalent to their innovator brand. At least half of the medicine (21/42, 50% and nursing (6/9, 66.6% students, compared to pharmacy students (5/11, 45.5%, believed that higher safety standards are required for proprietary medicines than for generic medicines. Most of them agreed that they need more information on the safety, quality, and efficacy aspects of generics (59/62, 95.2%. All three groups of healthcare students, despite variations in their responses, demonstrated a deficiency in knowledge and misconception regarding generic medicines. Training on issues surrounding generic drugs in healthcare training institutions is highly needed among future healthcare providers in Sierra Leone.

    The Brazilian constitution guarantees the right to health, including access to medicines. In May 2004, Brazil's government announced the "Farmácia Popular" Program (FPP) as a new mechanism to improve the Brazilian population's access to medicines. Under FPP, a selected list of medicines is subsidized by the government and provided in public and private pharmacies. The aim of this study is to describe the historical stages of the FPP and to identify associated changes in the geographical accessibility of medicines through the FPP over time. It was performed documentary review and an ecological study assessing program coverage in terms of number of facilities and a FPP Pharmacy Facilities Density (PFD) index at national and regional levels from 2004 to 2013, using the FPP database. We used geographic information system mapping to depict a pharmaceutical facilities density (PFD) index at the municipality level on thematic maps. A growth of the PFD index coincident with the phases of the FPP was noticed. In the public sector, the program started in 2004; by 2006, there was a sharp increase in the numbers of participating pharmacies, stabilizing in 2009. In the private sector, the program started in 2006; by 2009 the PFD ratio had increased substantially and it continued to grow through 2011. There was an increase in FPP coverage in most regions between 2006, when the private pharmacy component started, and 2013, but participating pharmacies remain unequally distributed across geographical regions. Specifically, the wealthy areas in the South and Southeast have higher coverage, with lower coverage mostly in the North and Northeast, relatively poorer areas with greater need for access to medicines, health care, and other basic services such as potable water and sanitization. There has been a substantial increase in the number of pharmacies participating in the FPP over time. This has led to greater program coverage and has potentially improved access to FPP medicines in

    Full Text Available Background: In most cases, the work of medical doctors, be they general practitioners or specialists, involves some dimension of health promotion (HP. There is thus ample justification for increasing the awareness of medical students vis-à-vis HP and its relevance for their future practice.Methods: In the context of a major curriculum reform (problem-based learning [PBL] at the Faculty of Medicine of the University of Geneva in the mid-1990s, several steps were taken to strengthen HP throughout the curriculum and include HP in its key domains as defined by the Ottawa Charter (OC.Results: First, the political dimension of HP was developed in a series of first- and fifth-year lectures and third-year workshops; second, community action was strengthened through a third year one-month community immersion program; third, the development of personal skills was integrated into second- and third-year PBL cases and into fourth-and fifth-year learning activities in clinical settings as well as second- and third-year HP electives; in terms of reorienting health services, the chosen approach included the development of a HP-specific track in the context of a Certificate of Advanced Studies (CAS in Community Health and a Master of Advanced Studies(MAS in Public Health. Furthermore, a supportive intra-university environment was created through a collaborative convention with Health Promotion Switzerland, which is in charge of coordinating HP in Switzerland.Conclusion: In our view, HP teaching for medical students seems all the more relevant given that future medical doctors will have to take care of an increasing number of patients likely to develop chronic non-communicable diseases.

    Giving an opinion on disputable paternity, concerning monozygotic twins in practice at the Department of Forensic Medicine (Silesian Academy of Medicine, Katowice) demonstrated their ideal agreement according to examined genetic markers possible. Even the mutation, which was revealed using the RFLP-VNTR method was the same for both twin sisters. In the case of dizygotic twins a firm differentiation of paternity index and probability of paternity was proved. This was the consequence of independent features segregation in first, reductive meiotic division. While the rare, out-ladder allele 16 at the CSF1PO locus was transmitted to both twins: a daughter and a son by the putative father.

    Robot-assisted surgery operations are being performed more frequently in the world these years. In order to have a macroscopic view of publication activities about robotic surgery, the first bibliometric analysis was conducted to investigate the publication distributions of robotic surgery. The original articles about robotic surgery were extracted from the Science Citation Index Expanded (SCI-E) on Web of Science and analyzed concerning their distributions. We also explored the potential correlations between publications of different countries and their Gross Domestic Product (GDP). The total number of original articles retrieved from SCI-E was 3362 from 1994 to 2015. The number of original articles published in the last decade has a burgeoning increase of 572.87% compared with that published in the former decade. The leading country was USA who have published 1402 pieces of articles (41.701%), followed by Germany with 342 (10.173%). The journal published the highest number of original articles was Journal of Endourology with 237 (7.049%), followed by Surgical Endoscopy and Other Interventional Techniques (188, 5.592%). There was strong correlations between publication numbers and GDP of different countries (r(2) = 0.889, p research activities has the potential to guide future trend in the field of robotic surgery. There is a skyrocket trend of robotic surgery in medical research over the last two decades, and countries with high GDP tend to make more contributions to the medical field of robotic surgery.

    In 2007, the Lake Erie College of Osteopathic Medicine initiated its Primary Care Scholar Pathway (PCSP), a 3-year osteopathic predoctoral education curriculum. To assess preliminary outcomes of the PCSP curriculum. Scores for the Comprehensive Osteopathic Medical Licensing Examination (COMLEX-USA) Levels 1 and 2-Cognitive Evaluation (CE) and pass rates for Level 2-Performance Evaluation (PE) were obtained for individuals who graduated from the PCSP program in 2010, 2011, and 2012. Scores for Levels 1 and 2-CE were compared with national mean scores. Acceptance rates for residency programs were also recorded. Nineteen PCSP graduates were included in the study: 3 graduated in 2010, 6 graduated in 2011, and 10 graduated in 2012. Scores for PCSP students were not significantly different than national average scores for COMLEX-USA Levels 1 and 2-CE (P>.05). All 19 PCSP graduates passed the COMLEX-USA Level 2-PE on the first attempt, and all graduates were accepted into primary care residency programs. The COMLEX-USA scores of PCSP graduates were similar to national mean scores, suggesting that it is possible for osteopathic medical students to attain the same level of education as students of 4-year programs in less time. A 3-year osteopathic predoctoral education curriculum would allow students to complete their education at a reduced cost. This potential reduction in debt burden could encourage more students to pursue a primary care career and thus could help address the shortage of primary care physicians in the United States.

    Parasitic diseases are common throughout the world. Evaluation of regional epidemiological data is needed to determine protective measures and treatment strategies. This study evaluates the parasites detected in Hacettepe University Faculty of Medicine Parasitology Laboratory. Of the 87,100 clinical samples evaluated in the study, 85,707 (98.4%) were from stool samples. Parasites were shown in 3,681 (4.2%) of the samples from 2,906 patients. The most common parasites were Giardia intestinalis (40%), Blastocystis spp. (22%), Entamoeba coli (12%), Dientamoeba fragilis (9%), Enterobius vermicularis (5%), Echinococcus spp. (4%) and Taenia spp. (3%) respectively. When distribution among years was evaluated, G. intestinalis, the most common parasite, had a tendency to decrease after 2004 whereas cases with Blastocystis spp. showed a clear increase in 2011 and 2012. The downward trend in parasite-positive cases also stopped in the last two years, in parallel to the increase of Blastocystis spp. During the study, Leishmania spp. and Plasmodium spp. were detected in four patients each. This study evaluated the results of a laboratory that scans a large number of patients in our region. Data obtained from different regions will allow to direct strategies to diagnose, treat and implement preventive measures against parasitic diseases in our country.

    BACKGROUND: The validity of children's self-reports on medicine use has not been reported. OBJECTIVE: To determine the agreement between parents' and children's reports of medicine use for 5 common complaints and to analyze predictors for disagreement. METHODS: We used the child-parent validation......, difficulties in falling asleep, nervousness, and asthma. RESULTS: The percent agreement was lowest with medicine use for headache (64.6%), but was very high for the other 4 complaints (85.3-91.8%). The simple kappa coefficients were moderate to good for medicine use for headaches, stomachache, and asthma (0.......31-0.58) but poor for difficulties in falling asleep and nervousness. Children who had the specific complaint during the previous month were more likely than their parents to report more frequent medicine use. CONCLUSIONS: We have some confidence in young adolescents' self-reports of medicine use, as the results...

    Full Text Available Evidence-based medicine (EBM has developed as the dominant paradigm of assessment of evidence that is used in clinical practice. Since its development, EBM has been applied to integrate the best available research into diagnosis and treatment with the purpose of improving patient care. In the EBM era, a hierarchy of evidence has been proposed, including various types of research methods, such as meta-analysis (MA, systematic review (SRV, randomized controlled trial (RCT, case report (CR, practice guideline (PGL, and so on. Although there are numerous studies examining the impact and importance of specific cases of EBM in clinical practice, there is a lack of research quantitatively measuring publication trends in the growth and development of EBM. Therefore, a bibliometric analysis was constructed to determine the scientific productivity of EBM research over decades.NCBI PubMed database was used to search, retrieve and classify publications according to research method and year of publication. Joinpoint regression analysis was undertaken to analyze trends in research productivity and the prevalence of individual research methods.Analysis indicates that MA and SRV, which are classified as the highest ranking of evidence in the EBM, accounted for a relatively small but auspicious number of publications. For most research methods, the annual percent change (APC indicates a consistent increase in publication frequency. MA, SRV and RCT show the highest rate of publication growth in the past twenty years. Only controlled clinical trials (CCT shows a non-significant reduction in publications over the past ten years.Higher quality research methods, such as MA, SRV and RCT, are showing continuous publication growth, which suggests an acknowledgement of the value of these methods. This study provides the first quantitative assessment of research method publication trends in EBM.

    The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics. The 50 highest cited articles related to Anterior Cruciate Ligament Injury were searched in Thomson ISI Web of Science® by the use of defined search terms. All types of scientific papers with reference to our topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type and level of evidence. The 50 highest cited articles had up to 1624 citations. The top ten papers on this topic were cited 600 times at least. Most papers were published in the American Journal of Sports Medicine. The publication years spanned from 1941 to 2007, with the 1990s and 2000s accounting for half of the articles (n = 25). Seven countries contributed to the top 50 list, with the USA having by far the most contribution (n = 40). The majority of articles could be attributed to the category "Clinical Science & Outcome". Most of them represent a high level of evidence. Scientific articles in the field of ACL injury are highly cited. The majority of these articles are clinical studies that have a high level of evidence. Although most of the articles were published between 1990 and 2007, the highest cited articles in absolute and relative numbers were published in the early 1980s. These articles contain well established scoring- or classification systems. The

    Kampo medicine is traditional Japanese medicine, which originated in ancient traditional Chinese medicine, but was introduced and developed uniquely in Japan. Today, Kampo medicines are integrated into the Japanese national health care system. Incident reporting systems are currently being widely used to collect information about patient safety incidents that occur in hospitals. However, no investigations have been conducted regarding patient safety incident reports related to Kampo medicines. The aim of this study was to survey and analyse incident reports related to Kampo medicines in a Japanese university hospital to improve future patient safety. We selected incident reports related to Kampo medicines filed in Toyama University Hospital from May 2007 to April 2017, and investigated them in terms of medication errors and adverse drug events. Out of 21,324 total incident reports filed in the 10-year survey period, we discovered 108 Kampo medicine-related incident reports. However, five cases were redundantly reported; thus, the number of actual incidents was 103. Of those, 99 incidents were classified as medication errors (77 administration errors, 15 dispensing errors, and 7 prescribing errors), and four were adverse drug events, namely Kampo medicine-induced interstitial pneumonia. The Kampo medicine (crude drug) that was thought to induce interstitial pneumonia in all four cases was Scutellariae Radix, which is consistent with past reports. According to the incident severity classification system recommended by the National University Hospital Council of Japan, of the 99 medication errors, 10 incidents were classified as level 0 (an error occurred, but the patient was not affected) and 89 incidents were level 1 (an error occurred that affected the patient, but did not cause harm). Of the four adverse drug events, two incidents were classified as level 2 (patient was transiently harmed, but required no treatment), and two incidents were level 3b (patient was

    The aim of the study is to present the results and experience in the management of complaints in a transfusion service in order to draw attention to the importance of this segment of quality management and to stimulate publication of other studies on the topic. This study is based on data from the Croatian Institute of Transfusion Medicine obtained by analysis of complaints recorded during a 13-year period (1998-2010). The distribution of the types and frequencies of complaints is presented, along with the level of their justifiability and criticality. The dynamics of the complaints is analysed overall and within particular categories. In addition, corrective actions and other factors that may have influenced the trends observed are discussed. During the study period, 817 complaints were received, most of which (40.9%) referred to the positive direct antiglobulin test in red cell concentrates, followed by blood product issuing and distribution (12.9%) and blood product quality (9.4%). Of the 817 complaints, 177 (21.7%) were assessed as serious and 645 (78.9%) as justified based on the testing performed. Data collected by systematic recording and analysis of complaints provide a basis for problem identification, implementation of corrective and preventive actions, and improvement of product and service quality, and, thereby, customer satisfaction.

    Zamioculcas zamiifolia, an unusually drought resistant medicinal plant native to tropical east Africa and subtropical southeast Africa, including the countries Kenya, Malawi, Mozambique, South-Africa, Tanzania and Zimbabwe, is described as a living fossil which may have evolved as early as 42 million years ago. It belongs to the notoriously toxic family Araceae giving it, through association, a reputation for being toxic; despite little or no systematic evidence exists to support this claim. As an ancient plant it has sustained substantial climate changes and attacks from millions of generations of pathogenic microorganisms, which encouraged search for novel natural products from this source. Seven natural products have been characterized from leaves and petioles of Z. zamiifolia, including the novel main compound of the leaves, apigenin 6-C-(6″-(3-hydroxy-3-methyl-glutaroyl)-ß-glucopyranoside). The structure determinations were based on extensive use of 2D NMR spectroscopic techniques and high-resolution mass spectrometry. Initial toxicological experiment on extracts from Z. zamiifolia using brine shrimp lethality assay did not indicate lethality to the shrimps providing disproving evidence for the assumption of Z. zamiifolia's toxic character.

    This study described the patient population and the health care services delivered in the Air Force Flight and Operational Medicine Clinics (FOMCs) over the past 10 years. A cross-sectional analysis was performed on the retrospective cohort of patients who received care at a FOMC from 2003 to 2012. A total of 714,157 individuals, generating 4,829,626 encounters, were included in the cohort. They were predominately male service members under the age of 41. One-fifth of individuals were retirees and family members, with one-third being in the pediatric age range. The cohort accessed health care services for three primary reasons: health examinations (28%), occupational dispositions (18%), and primary care (54%). When primary care was sought, the predominate health conditions were upper respiratory infections, back problems, and nontraumatic joint disorders. When services and procedures were a component of the care, they were predominately associated with health examinations involving ophthalmologic, auditory, and cardiac screening tests. Individuals accessing the FOMCs had relatively low need for access to health care services, requiring a median of two annual encounters. This study provided insight into the health care delivered in FOMCs and establishes a foundation for future planning and management of FOMC health care delivery.

    Fifty children with cancer have been studied by MR. The patients studied include ten with lymphoma, nine with neuroblastoma, five with rhabdomyosarcoma, six with leukemia, five with Ewings sarcoma, four with Wilms tumor and several with other miscellaneous tumors. The results of scanning show that MR is well tolerated by children. Primary tumor has been identified in every case. Metastases have been identified in many patients. MR has proved helpful in identifying the organ of origin of a tumor. Because of excellent vessel visualization it is helpful in planning surgical resection of a tumor. In addition, in a number of patients MR has proved helpful in monitoring the response of tumor to nonsurgical therapy. With continued improvement in image quality it is believed that MR has a major role to play in pediatric tumor imaging [fr

    Full Text Available Introduction: The lack of knowledge regarding the incidence of adverse drug reactions in the hospital setting and their impact on morbidity and mortality is, nowadays, a major health problem in Angola. In the last years, notifications of adverse drug reactions have been practically null, namely at a hospital level. It is of great importance to characterize the incidence of adverse drug reactions occurring in a hospital setting, in order to implement measures towards improving the quality of healthcare services. Material and Methods: We conducted a descriptive, prospective observational study to characterize the incidence of adverse drug reactions (ADRs in patients admitted to the Central Hospital “Josina Machel” in Luanda during the year 2014. An intensive monitoring through active search for adverse reactions possibly related with the drugs prescribed to patients was performed. Results: Of a total of 2041 hospitalized patients, 175 had adverse drug reactions. The incidence rate was 4.74% in the medicine service (n = 1077 and 12.86% in the therapy service (n = 964. A total of 209 adverse drug reactions were identified, averaging 1,2 adverse drug reactions per patient. The highest incidence rate of adverse drug reactions was recorded in patients aged between 18 and 35 years old, with 79 patients (45.14%. With regard to therapeutic class, it was found that antimicrobials were the drugs most commonly associated with adverse reactions, with 71 notifications (40.57%, followed by analgesics, antipyretics and anti-inflammatory steroids with 20,00%. Quinine and artesunate were the antimicrobials most frequently implicated in causing an adverse drug reaction, with 25 (14.29% and 15 (8.57% notifications respectively. In the group of anti-inflammatory drugs, diclofenac stood out with 13 notifications (7.43%. The most common clinical manifestations were skin rash, which corresponded to 23,44% of the total number of adverse drug reactions, followed by

    This study extends available evidence about the relationship between scores on the Step 2 Clinical Skills (CS) component of the United States Medical Licensing Examination and subsequent performance in residency. It focuses on the relationship between Step 2 CS communication and interpersonal skills scores and communication skills ratings that residency directors assign to residents in their first postgraduate year of internal medicine training. It represents the first large-scale evaluation of the extent to which Step 2 CS communication and interpersonal skills scores can be extrapolated to examinee performance in supervised practice. Hierarchical linear modeling techniques were used to examine the relationships among examinee characteristics, residency program characteristics, and residency-director-provided ratings. The sample comprised 6,306 examinees from 238 internal medicine residency programs who completed Step 2 CS for the first time in 2005 and received ratings during their first year of internal medicine residency training. Although the relationship is modest, Step 2 CS communication and interpersonal skills scores predict communication skills ratings for first-year internal medicine residents after accounting for other factors. The results of this study make a reasonable case that Step 2 CS communication and interpersonal skills scores provide useful information for predicting the level of communication skill that examinees will display in their first year of internal medicine residency training. This finding demonstrates some level of extrapolation from the testing context to behavior in supervised practice, thus providing validity-related evidence for using Step 2 CS communication and interpersonal skills scores in high-stakes decisions.

    Following the recommendations of the World Association for Disaster and Emergency Medicine (WADEM; Madison, Wisconsin USA) to develop standards for training the undergraduates in disaster-relevant fields (2004), a German curriculum was approved in 2006. This paper aims to describe the level of training and interest of medical students nine years later. Problem The aim of this study was to assess the self-perception of medical students' knowledge and interest in disaster medicine nine years after the implementation of a standardized disaster medicine curriculum in German medical schools. This prospective, cross-sectional, observational study was conducted with medical students in Germany using a web-based, purpose-designed questionnaire consisting of 27 mandatory and 11 optional questions. Nine hundred ninety-two students from 36 of 37 medical schools in Germany participated. More than one-half of medical students were aware of the field of disaster medicine. One hundred twenty-one students undertook training internally within their university and 307 undertook training externally at other institutions. Only a small content of the curriculum was taught. A difference in self-perception of knowledge between trained and untrained participants was found, despite the level of training being low in both groups. Participants were generally highly motivated to learn disaster medicine in a variety of institutions. German students are still largely not well educated regarding disaster medicine, despite their high motivation. The curriculum of 2006 was not implemented as originally planned and the number of trained students still remains low as the self-perception of knowledge. Currently, there is no clear and standardized training concept in place. A renewal in the agreement of implementation of the curriculum at medical schools should be targeted in order to follow the recommendation of WADEM.

    Electronic health records (EHRs), resident duty hour restrictions, and Patient-centered Medical Home (PCMH) innovations have all impacted the clinical practices of residency programs over the past decade. The University of Washington Family Medicine Network (UWFMN) residencies have collaborated for 10 years in collecting and comparing data regarding the productivity and operations of their training programs to identify the program-level effects of such changes. Based on five survey results from 2000 to 2010, this study examines changes in faculty and resident productivity and staffing models of UWFMN residency training clinics using a standardized methodology, specifically describing the productivity impact of EHR changes and duty hour restrictions and the implementation of the PCMH by residencies. Data were systematically collected via standardized questionnaire, evaluated for quality, clarified, and then analyzed. Resident productivity decreased over the 10-year interval, with resident total yearly patient visits down 17.2%. Core family medicine faculty productivity was highly variable among programs, and nonphysician provider visits increased. Faculty part-time status increased. Front office, medical assistant, and nursing staffing grew significantly, but other administrative staff decreased, resulting in minimal change in total non-provider staffing. A majority of programs engaged in PCMH initiatives in 2010 and had implemented an EHR. Physician productivity in UWFMN residency programs decreased for all resident physicians from 2000 to 2010, likely due to a combination of decreased resident duty hours and other clinical practice changes. Productivity trends have implications for the structure and training requirements for family medicine residency programs.

    Practitioners and researchers from China, the largest user of complementary and alternative medicine (CAM), have been publishing an increasing number of scientific articles in world-famous CAM journals in recent years. However, the status of CAM research in the three major regions of China, the Mainland, Taiwan and Hong Kong has, until now, not been reported. In this study, we compared articles from these three regions published in international CAM journals from 2000 to 2009 using PubMed database and the Journal Citation Reports. The study results showed that the number of published articles from Mainland China increased significantly from 2000 to 2009, particularly since 2005. Meanwhile, the number of published articles from Taiwan also increased, whereas those from Hong Kong remained steady. Clinical trials and randomized controlled trials from Chinese authors both took a small percentage of the total. The impact factors of the journals in which these articles were published suggested similar academic levels whereas the average number of citation of articles from the Mainland was less than those from the other two regions. Journal of Ethnopharmacology, American Journal of Chinese Medicine, Journal of Alternative and Complementary Medicine and Evidence-based Complementary and Alternative Medicine were the most popular journals for Chinese authors.

    This article examines 18th-century European warfare, tracing the first formal codifications of conventions of war, frequently introduced by military physicians and initially regarding the treatment of the sick and wounded. It outlines to what extent these conventions were followed in practice, particularly in the challenging environment of American irregular warfare, with a focus on the most well-known incident of "biological warfare" in the period: the deliberate spread of smallpox by British officers among Amerindians in 1763. More broadly, it demonstrates that the history of military medicine provides a fruitful method with which to uncover assumptions about the ethics of war.

    Full Text Available Objective: To investigate the model, quality as well as effect of teaching-in-English in five-year clinical medicine program of Hainan Medical University. Methods: The questionnaire was carried out among clinical medicine undergraduates of 2012–2015 grades in Hainan Medical University, to investigate studying time, studying habits and the impact of teaching in English. Additionally results of CET-4, CET-6 and overseas internship from undergraduates of 2012–2015 grade, as well as the result of phased medical licensing examination and post-graduate entrance examination from undergraduates of 2012 were accordingly collected from the Teaching Management Department. Results: For the Chinese students in international classes, the average time of self-study was 161.49 min, 58.3% had preview before classes, and 90.7% had habit of review after classes. Thus the first time pass rate, total pass rate, first time excellent rate and total excellent rate of CET-4 and CET-6 of international classes were significantly higher than those of regular classes. The result of post-graduate entrance examination in 2016 showed that the score, pass rate and acceptance rate of international classes of 2012 grade were significantly higher those of regular classes (P < 0.01. Conclusions: Teaching-in-English reform in Hainan Medical University has achieved initial success. Chinese students from international classes are superior to those from regular classes in many aspects. However, there are still many problems, and effective measures should be implemented to promote teaching quality continuously.

  5. Scaling up family medicine training in Gezira, Sudan – a 2-year in-service master programme using modern information and communication technology: a survey study

    Science.gov (United States)

    2014-01-01

    Background In 2010 the Gezira Family Medicine Project (GFMP) was initiated in Gezira state, Sudan, designed as an in-service training model. The project is a collaboration project between the University of Gezira, which aims to provide a 2-year master’s programme in family medicine for practicing doctors, and the Ministry of Health, which facilitates service provision and funds the training programme. This paper presents the programme, the teaching environment, and the first batch of candidates enrolled. Methods In this study a self-administered questionnaire was used to collect baseline data at the start of the project from doctors who joined the programme. A checklist was also used to assess the health centres where they work. A total of 188 out of 207 doctors responded (91%), while data were gathered from all 158 health centres (100%) staffed by the programme candidates. Results The Gezira model of in-service family medicine training has succeeded in recruiting 207 candidates in its first batch, providing health services in 158 centres, of which 84 had never been served by a doctor before. The curriculum is community oriented. The mean age of doctors was 32.5 years, 57% were males, and 32% were graduates from the University of Gezira. Respondents stated high confidence in practicing some skills such as asthma management and post-abortion uterine evacuation. They were least confident in other skills such as managing depression or inserting an intrauterine device. The majority of health centres was poorly equipped for management of noncommunicable diseases, as only 10% had an electrocardiography machine (ECG), 5% had spirometer, and 1% had a defibrillator. Conclusions The Gezira model has responded to local health system needs. Use of modern information and communication technology is used to facilitate both health service provision and training. The GFMP represents an example of a large-volume scaling-up programme of family medicine in Africa. PMID:24443978

    Art is defined as the expression or application of the human creative skill and imagination, producing works to be appreciated primarily for their beauty or emotional power. "Ars medica" and "Ars musica" represent two concepts which have been mutually intertwined since the ancient times. Through history, many extraordinary physicians have shown talent towards making and performing music. Guided by the passion for medicine and music, since 2006 the students from the University of Rijeka, Faculty of Medicine have founded an informal group named "In honour of Asclepius and Orpheus" under the aegis of the Croatian Scientific Society for the History of Health Culture. The group organizes many musical activities such as concerts, musical recitals and events, among which are the most important - the traditional annual concert of Croatian medical students and the European Medical Students Orchestra and Choir project. Apart from Rijeka, they performed several times in Ljubljana, Zagreb, Pula, Karlovac, Krk, Opatija and Crikvenica. The members of this group plan their future work guided by the principles that motivate every physician-musician - art.

    2010-03-01

    Full Text Available France and the United Kingdom are influential backers when it comes to the global governance of aid to developing countries. A short history of the contributions made by these former colonial powers to ODA is presented, covering the institutions concerned, strategies conducted and funding provided. These institutions have undergone complex changes since the initial phase of making “improvements” in the colonies up until recent reforms. Their ambitious strategies, grounded on considerable research, have received attention from a multilateral audience, turning the colonial question into a global issue. The vision of aid in both France and the UK is broader than is conveyed by the calculations that are carried out by the OECD’s DAC. Though subject to political contingencies, aid from these countries amounts to a substantial contribution that seeks to respond to various development needs.

    2004-03-01

    Pollen and charcoal records from two large, shallow lakes reveal that throughout most of the past 50,000 yr Noel Kempff Mercado National Park, in northeastern lowland Bolivia (southwestern Amazon Basin), was predominantly covered by savannas and seasonally dry semideciduous forests. Lowered atmospheric CO 2 concentrations, in combination with a longer dry season, caused expansion of dry forests and savannas during the last glacial period, especially at the last glacial maximum. These ecosystems persisted until the mid-Holocene, although they underwent significant species reassortment. Forest communities containing a mixture of evergreen and semideciduous species began to expand between 6000 and 3000 14C yr B.P. Humid evergreen rain forests expanded to cover most of the area within the past 2000 14C yr B.P., coincident with a reduction in fire frequencies. Comparisons between modern pollen spectra and vegetation reveal that the Moraceae-dominated rain forest pollen spectra likely have a regional source area at least 2-3 km beyond the lake shore, whereas the grass- and sedge-dominated savanna pollen spectra likely have a predominantly local source area. The Holocene vegetation changes are consistent with independent paleoprecipitation records from the Bolivian Altiplano and paleovegetation records from other parts of southwestern Amazonia. The progressive expansion in rain forests through the Holocene can be largely attributed to enhanced convective activity over Amazonia, due to greater seasonality of insolation in the Southern Hemisphere tropics driven by the precession cycle according to the Milankovitch Astronomical Theory.

    This essay comprises 2 parts. It aims to recognize the public service of psychiatrists of the Département de psychiatrie de l'Université de Montréal who served at the provincial level of the Ministry of Health and Social Services for deinstitutionalisation of policies and organisation of services, at the service of people with severe mental disorders. First with Dr. Camille Laurin post-face of the 1962 book Les fous crient au secours! (Mentally ill patients cry for help); then the insight on the latest phase of differentiated specialised clinics by Dr. Denis Lazure, who participated in 1962 to the Bédard, Lazure, Roberts commission that launched community psychiatry, but who will also be Social Affairs Minister in the late '70 s; Dr. Arthur Amyot will sail through the budgetary issues when in the beginning of the '80s the mental health directorate was under Social Affairs; Dr. Luc Blanchet will be associated to a rich production of interdisciplinary reports by the advisory Mental Health Committee until its dismissal in 2003; and finally, Dr. André Delorme, who probably has the record of longevity at the head of the mental health directorate, transferred in 2003 under the deputy minister for medical and university affairs.The essay will propose since the beginning a grid or referential of four health services analysis. First; the arguments for community care by British and Italian psychiatrists and researchers, Thornicroft and Tansella. Second; system issues of mental health reforms proposed by Canadian psychiatric nurse and researcher Paula Goering. Third; the model of socio-political regulation of health system proposed by the Université de Montréal' health administration researcher Dr. André-Pierre Contandriopoulos; and Fourth; the structural tension between the medical and social sector signaled by the American medical sociologist, Leutz.The same phases of deinstitutionalization in other countries as UK, took place as followed: a) the asylum phase (before 1960); b) the psychiatry community (1960-2000); and c) the differentiated system (since 2000). The essay will evidence the long march towards hospitals without walls, interdisciplinary work, tension between cure and rehabilitation and a relative decreasing budget. This in conjunction with vulnerability in organisation and leadership, attributed to tension or burn out has revealed system deficits like the trans-institution towards homelessness or towards the judiciary system. The essay will conclude with a discussion on the opportunities and challenges of the very new Law 10 that reforms the general governance of the provincial and regional health and social services and hopes for a more balanced mental health care system in Quebec.

    Calcium and bone metabolism remain key concerns for space travelers, and ground-based models of space flight have provided a vast literature to complement the smaller set of reports from flight studies. Increased bone resorption and largely unchanged bone formation result in the loss of calcium and bone mineral during space flight, which alters the endocrine regulation of calcium metabolism. Physical, pharmacologic, and nutritional means have been used to counteract these changes. In 2012, heavy resistance exercise plus good nutritional and vitamin D status were demonstrated to reduce loss of bone mineral density on long-duration International Space Station missions. Uncertainty continues to exist, however, as to whether the bone is as strong after flight as it was before flight and whether nutritional and exercise prescriptions can be optimized during space flight. Findings from these studies not only will help future space explorers but also will broaden our understanding of the regulation of bone and calcium homeostasis on Earth.

    The study of islands as model systems has played an important role in the development of evolutionary and ecological theory. The 50th anniversary of MacArthur and Wilson's (December 1963) article, 'An equilibrium theory of insular zoogeography', was a recent milestone for this theme. Since 1963, island systems have provided new insights into the formation of ecological communities. Here, building on such developments, we highlight prospects for research on islands to improve our understanding of the ecology and evolution of communities in general. Throughout, we emphasise how attributes of islands combine to provide unusual research opportunities, the implications of which stretch far beyond islands. Molecular tools and increasing data acquisition now permit re-assessment of some fundamental issues that interested MacArthur and Wilson. These include the formation of ecological networks, species abundance distributions, and the contribution of evolution to community assembly. We also extend our prospects to other fields of ecology and evolution - understanding ecosystem functioning, speciation and diversification - frequently employing assets of oceanic islands in inferring the geographic area within which evolution has occurred, and potential barriers to gene flow. Although island-based theory is continually being enriched, incorporating non-equilibrium dynamics is identified as a major challenge for the future. © 2014 John Wiley & Sons Ltd/CNRS.

    1994-01-01

    A vision of the future is presented in the context of ongoing social and technological development. The most compelling moral and ethical issue facing the world at the close of the 20th Century is to help the peoples of the poorer countries in their struggle for a reasonable quality of life, while at the same time they face a dramatic increase in their population. The new society will need vastly more energy than the world of today. It will need all supply options that can provide the energy in an economic environmentally sustainable manner. Nuclear energy will be a vital element in this supply pattern, provided that it continues to demonstrate the imperatives of safe operation and economic competitiveness. Other applications of nuclear energy will add their own impact to the improving quality of life. 5 refs., 1 fig

    On the occasion of the celebration of the first half-century of Yang--Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted physical reality, that is, its "phenomenology". There is nothing original in this work, except, perhaps, my own points of view. But I hope that the older practitioners of the field will find here grounds for nostalgia, or good reasons to disagree with me. Younger addicts may learn that history does not resemble at all what is reflected in current textbooks: it was orders of magnitude more fascinating.

    The idea of starting an astronomical observatory in the state of Uttar Pradesh in India germinated through the initiative of a scholarly statesman Babu Sampurnanandji. His interest in astrology coupled with his academic bent of mind got him interested in modern astronomy. Being then Education Minister and later Chief Minister of Uttar Pradesh, he established an astronomical observatory at Varanasi on April 20, 1954. Later on it was shifted to Manora Peak, Nainital. Four reflectors were commissioned at Manora Peak. For solar research an H alpha petrol unit and a horizontal solar spectrograph was setup. A detailed project report for installation of a 4-m class optical telescope was prepared indigenously in late 1980, however, the project could not take off. With the generous support of the Department of Science and Technology, the institute established a 3.6-m new technology optical telescope and a 1.3-m wide field optical telescope at a new observing site called Devasthal. Now a 4-m liquid mirror telescope is also being installed at the same observing site. I present here a brief journey of the observatory beginning right from its birth in 1954 till now.

    Children's books published between 1910 and 1960 reflect a changing world and new attitudes toward children. In 1910, although some of the moral tales of the earlier Puritan era survived, the didactic period in children's books was nearly over. From 1910 to 1925, a transitional period, writers began to look toward the children's own world. Then,…

    2004-09-01

    The civil rights struggle for equal educational opportunity has yet to be achieved at the start of the 21st century. Inequality persists but problem and remedy are refrained from integrating schools, to ensuring equal access in resegregated settings, to closing the performance gap. As seen through ecological theory (R. S. Weinstein, 2002b), complex, multilayered, and interactive negative self-fulfilling prophecies create or perpetuate educational inequities and unequal outcomes. Society has failed to grapple with its entrenched roots in the achievement culture of schools. If this insidious dynamic is to be changed, an educational system that sorts for differentiated pathways must be replaced with one that develops the talents of all. Psychology has a critical role to play in promoting a new understanding of malleable human capabilities and optimal conditions for their nurturance in schooling. ((c) 2004 APA, all rights reserved)

    2014-05-14

    Since its formal inception in 1964-1965, Kohn-Sham density-functional theory (KS-DFT) has become the most popular electronic structure method in computational physics and chemistry. Its popularity stems from its beautifully simple conceptual framework and computational elegance. The rise of KS-DFT in chemical physics began in earnest in the mid 1980s, when crucial developments in its exchange-correlation term gave the theory predictive power competitive with well-developed wave-function methods. Today KS-DFT finds itself under increasing pressure to deliver higher and higher accuracy and to adapt to ever more challenging problems. If we are not mindful, however, these pressures may submerge the theory in the wave-function sea. KS-DFT might be lost. I am hopeful the Kohn-Sham philosophical, theoretical, and computational framework can be preserved. This Perspective outlines the history, basic concepts, and present status of KS-DFT in chemical physics, and offers suggestions for its future development.

    Johnson, C. E.; Johnson, J. A.

    2012-01-01

    The Mössbauer Effect was discovered in 1957. In 1960 Mössbauer spectroscopy was born when two important papers appeared on (i) the magnetic hyperfine interaction and (ii) the electric monopole (isomer shift) and quadrupole interactions. These transformed an interesting phenomenon into a method for probing solids. Applications to magnetism, metals and alloys, chemical compounds, biological molecules, geology, archaeology and other sciences followed and are still of current interest. Two areas of research where Mössbauer spectroscopy is making unique contributions are in determining oxidation states in (i) glasses and (ii) nanoparticles. Some recent measurements are described.

  14. Fifty million years of herbivory on coral reefs: fossils, fish and functional innovations.

    Science.gov (United States)

    Bellwood, D R; Goatley, C H R; Brandl, S J; Bellwood, O

    2014-04-22

    The evolution of ecological processes on coral reefs was examined based on Eocene fossil fishes from Monte Bolca, Italy and extant species from the Great Barrier Reef, Australia. Using ecologically relevant morphological metrics, we investigated the evolution of herbivory in surgeonfishes (Acanthuridae) and rabbitfishes (Siganidae). Eocene and Recent surgeonfishes showed remarkable similarities, with grazers, browsers and even specialized, long-snouted forms having Eocene analogues. These long-snouted Eocene species were probably pair-forming, crevice-feeding forms like their Recent counterparts. Although Eocene surgeonfishes likely played a critical role as herbivores during the origins of modern coral reefs, they lacked the novel morphologies seen in modern Acanthurus and Siganus (including eyes positioned high above their low-set mouths). Today, these forms dominate coral reefs in both abundance and species richness and are associated with feeding on shallow, exposed algal turfs. The radiation of these new forms, and their expansion into new habitats in the Oligocene-Miocene, reflects the second phase in the development of fish herbivory on coral reefs that is closely associated with the exploitation of highly productive short algal turfs.

    1997-10-01

    Twenty-six white male workers who did the original plutonium research and development work at Los Alamos have been examined periodically over the past 50 y to identify possible health effects from internal plutonium depositions. Their effective doses range from 0.1 to 7.2 Sv with a median value of 1.25 Sv. As of the end of 1994, 7 individuals have died compared with an expected 16 deaths based on mortality rates of U.S. white males in the general population. The standardized mortality ratio (SMR) is 0.43. When compared with 876 unexposed Los Alamos workers of the same period, the plutonium worker's mortality rate was also not elevated (SMR = 0.77). The 19 living persons have diseases and physical changes characteristic of a male population with a median age of 72 y (range = 69 to 86 y). Eight of the twenty-six workers have been diagnosed as having one or more cancers, which is within the expected range. The underlying cause of death in three of the seven deceased persons was from cancer, namely cancer of prostate, lung, and bone. Mortality from all cancers was not statistically elevated. The effective doses from plutonium to these individuals are compared with current radiation protection guidelines.

    In the past brain imaging of term infants with hypoxic-ischemic encephalopathy (HIE) was performed with cranial ultrasound (cUS) and computed tomography (CT). Both techniques have several disadvantages sensitivity and specificity is limited compared with magnetic resonance imaging (MRI) and CT makes use of radiation. At present MRI including diffusion weighted MRI during the first week of life, has become the method of choice for imaging infants with HIE. In addition to imaging, blood vessels and blood flow can be visualized using MR angiography, MR venography, and arterial spin labeling. Since the use of these techniques additional lesions in infants with HIE, such as arterial ischemic stroke, sinovenous thrombosis, and subdural hemorrhages can be diagnosed, and the incidence appears to be higher than shown previously. Phosphorus magnetic resonance spectroscopy (MRS) has led to the concept of secondary energy failure in infants with HIE, but has not been widely used. Proton MRS of the basal ganglia and thalamus is one of the best predictors of neurodevelopmental outcome. cUS should still be used for screening infants admitted to a NICU with neonatal encephalopathy. In the future magnetic resonance techniques will be increasingly used as early biomarkers of neurodevelopmental outcome in trials of neuroprotective strategies.

    2014-12-01

    Flaring is a process during which waste gases are burned in an open atmosphere. The quantification of gas flaring emissions represents a major scientific concern due to its magnitude and related uncertainties. In global/regional emission inventories, this source, though releasing large amounts of pollutants in the atmosphere, is still poorly quantified if not missing. It can represent the main emission source of gaseous compounds and particles in some areas, as observed during the AMMA project in the Gulf of Guinea. Our study focuses on Africa, and includes Nigeria, which is one of the largest natural oil and gas reserve in the world. Africa is an important gas flaring area, since technologies for the exploitation of this energy source and the reduction of flaring activities have been only recently implemented. We have developed an emission inventory for gases and particles from flaring in Africa. We have first compiled the few published available dataset of fuel consumption from flaring. The spatial distribution of CO2 and black carbon (BC) emissions from gas flaring in 2011 is estimated using a methodology based on field reports and remote sensing (DMSP satellite data). Our results point out to the importance of flaring activities into the regional anthropogenic emissions in Africa over the period 1960-2011. Finally, the contribution of flaring to total anthropogenic emission can be large and needs to be accurately quantified.

    2012-01-01

    The 50th anniversary of the discovery of quasars in 1963 presents an interesting opportunity to ask questions about the current state of quasar research. Formatted as a series of interviews with noted researchers in the field, each of them asked to address a specific set of questions covering topics selected by the editors, this book deals with the historical development of quasar research and discusses how advances in instrumentation and computational capabilities have benefitted quasar astronomy and have changed our basic understanding of quasars. In the last part of the book the interviews address the current topic of the role of quasars in galaxy evolution. They summarise open issues in understanding active galactic nuclei and quasars and present an outlook regarding what future observational facilities both on the ground and in space might reveal. Its interview format, the fascinating topic of quasars and black holes, and the lively recollections and at times controversial views of the contributors make ...

  9. Cryogenics for high-energy particle accelerators: highlights from the first fifty years

    CERN Document Server

    AUTHOR|(CDS)2067931

    2016-01-01

    Applied superconductivity has become a key technology for high-energy particle accelerators, allowing to reach higher beam energy while containing size, capital expenditure and operating costs. Large and powerful cryogenic systems are therefore ancillary to low-temperature superconducting accelerator devices – magnets and high-frequency cavities – distributed over multi-kilometre distances and operating generally close to the normal boiling point of helium, but also above 4.2 K in supercritical and down to below 2 K in superfluid. Additionally, low-temperature operation in accelerators may also be required by considerations of ultra-high vacuum, limited stored energy and beam stability. We discuss the rationale for cryogenics in high-energy particle accelerators, review its development over the past half-century and present its outlook in future large projects, with reference to the main engineering domains of cryostat design and heat loads, cooling schemes, efficient power refrigeration and cryogenic flu...

    For the purposes of this research attachment theory was incorporated into the concept of emotional intelligence. The methodological starting point of this study was the assumption that the level of emotional intelligence and social competence is related to a steady feature, namely the type of attachment. Standardized questionnaires available in the Laboratory of Psychological Tests of the Polish Psychological Association were chosen to measure the level of emotional intelligence. However, the type of attachment was studied by Bartholomew's Self Description Test in my own translation. The study involved two groups of students, who were compared: 147 people from the Faculty of Health Sciences/Faculty of Nursing (nursing, midwifery, health promotion, cosmetology, emergency medicine, dietetics), and 181 people from the Faculty of Medicine (medicine), students in their second and third years of studies. A total of 328 people, aged 19-24, were tested. On the basis of the results it was stated that students of the Faculty of Health Sciences/Faculty of Nursing, as compared to students of the Faculty of Medicine, received significantly higher scores on the scale of the social competence scale, which investigated the efficiency of their behaviour in intimate situations. Moreover, statistical analysis proved that students of the Faculty of Health Sciences showed significantly higher scores than those studying at the Faculty of Medicine in the following fields: KKS-I subscale assessing social competencies in--conditioning effective behaviour in intimate situations, emotional intelligence measured with the INTE questionnaire,--awareness of their own emotional states and understanding their causes (DINEMO-I),--ability to recognize emotions in other people and understanding the reasons for the reactions expressed by them (DINEMO-Others)--emotional intelligence measured with the DINEMO questionnaire (DINEMO-general score). Women from both faculties showed higher social competence

    Population and Clinical Medicine (PCM) I & II constitute two of the nine courses established for the Warren Alpert Medical School of Brown University's (AMS) innovative dual-degree Primary Care-Population Medicine (PC-PM) program. The courses will run consecutively during students' third year in the program, in conjunction with the Longitudinal Integrated Clerkship (LIC). Throughout the courses, students will examine the intersection between population and clinical medicine with a focus on vulnerable populations, the social and community context of care, quality improvement, and leadership. In addition to attending class sessions in which students will engage with leaders in relevant fields, students will also draw from patient and population-level experiences in the LIC to plan and implement two projects: a community-based intervention to address a particular health issue, and a quality improvement project to change a small aspect of care delivery at a clinical site. Finally, leadership skills development sessions will be incorporated, and leadership practice will occur during implementation of student projects.

    147 cases of fatal poisonings in people due to narcotic abuse examined in the Forensic Medicine Department Silesian School of Medicine, Katowice in the years 1996-2002 have been presented in the paper. In the group examined there were 126 males and 21 females at the age of 16-44. Opium narcotics were found in 139 out of 147 cases and amphetamine derivatives in 18. Opiates were indicated in 58 individuals and amphetamine only in 8. In 35 poisoned people opiates with barbituric acid derivatives were found. In 3 cases death resulted after taking opiates and amphetamine derivatives. 1 individual died after taking opiates and substances of the phenothiazine group. In the organic fluids of 18 people opiates and medicines being derivatives of 1,4-benzodiazepine and barbituric acid were found. Amphetamine and derivatives of 1,4-benzodiazepine were found in 6 individuals and opiates, barbiturates, benzodiazepines and amphetamine in 1 individual. Concentrations of all the substances indicated ranged widely and were as follows: microgram/ml for opiates; microgram/ml for amphetamine; microgram/ml for 1.4-benzodiazepine derivatives and microgram/ml for barbituric acid derivatives. Ethanol was found in 18 individuals and its concentration was @1000.

    This paper puzzles over why symmetry, so central to particle physics today, was so little attended to in the 1950s when the need for it was becoming profound, with the notion of parity violation and other break-downs in conservation laws, such as angular momentum and charge conjugation. Group theory, including Lie groups, would also have helped understanding of the particle physics discoveries of the 1950s such as strange particles, resonances, and associated production. They were adopted ten years too late by the physics community. (UK)

    The impact of assisted reproductive technology (ART) on Swiss demography was quantified. From 1993 to 2012 the number of deliveries, including multiples, generated by ART was compared with overall delivery numbers. Swiss experts in ART collaborated in a consensus to increase successful outcomes, to reduce the incidence of complications of ART and to validate recommendations through statistical review of available data. Data generated between 1993 and 2012 and published by the Federal Office of Statistics (BfS) were compared with the Swiss database on ART (FIVNAT-CH) as organised by the Swiss Society of Reproductive Medicine (SGRM). From these analyses a panel of Swiss experts in ART extracted recommendations to improve current practice, to prevent complications related to ART and to recommend changes in current Swiss legislation dealing with ART. Since 1993 the age of women giving birth rose together with the number of women asking for ART. This demographic trend was reflected in a rise in the number of deliveries generated by ART (in 2012: 2.2%) and the proportion of multiple births (in 2012: 17.6%). The outcome of ART was most negatively influenced by the age of the treated patient. The number of retrieved oocytes decisively impacted the likelihood of delivery, the risk of multiple births and the incidence of ovarian hyperstimulation syndrome. Optimal ovarian stimulation should be designed for the retrieval of 10 to 15 oocytes per treatment. Swiss legislation should enable and stimulate a policy of elective single embryo transfer to avoid multiple births.

    Full Text Available In Finland, between 2003 and 2010 and parallel to the increase in the prevalence of insomnia-related symptoms among the general population, there has been a cessation of growth and even a decrease in the consumption of traditional hypnotics. The reasons behind this seemingly paradoxical situation are not known. We analyzed trends over the period 2000-2010 in the estimated consumption of traditional hypnotics and some new drugs that are destined for use in insomnia treatment. We used the annual wholesale statistical database compiled by the Finnish Medicine Agency, FIMEA, and data from the Finnish Drug Prescription Register. We found evidence to support two parallel trends in Finnish outpatient care. First, there seems to be a trend in which physicians increasingly comply with official guidelines for insomnia treatment, which partly accounts for the decrease in the consumption of traditional hypnotics. Second, at the same time, the first trend seems to be resulting in an increasing trend to treat insomnia patients with some new drugs that were not originally developed for insomnia treatment by prescribing these non-hypnotic drugs in small, sub-clinical doses. The current trend in practice may have contradictory effects on the treatment of insomnia. The long-term consequences of using low doses of drugs other than hypnotics to treat insomnia are not known and the situation should, therefore, be followed-up in subsequent studies. However, pharmacological treatment should never be a substitute for non-pharmacological treatments of insomnia.

    This article is based on the experience with 'The Human in Medicine' (HIM) courses that had been a part of the preclinical program of the Marmara Medical School. The evaluation of the HIM course in terms of its efficacy and the impressions of the students. Three groups of data were collected: (a) Students' feedbacks about the courses, (b) HIM final scores and (c) a thematic/content analysis of randomly selected students' reports. Stratified random sampling was used to select student reports for qualitative analysis. Content and thematic analyses were carried out by two researchers independently. In general, the HIM program was evaluated as moderate or above moderate by 60-80% of the students. Content and thematic analysis of student reports showed that there was a rich variety in individual definitions, descriptions of causal relationships and suggestions for possible solutions about themes medicalization and stigmatization. Student reports on the case were analysed in concordance with psychologic and social parameters. As a conclusion these results showed that program goals were mainly achieved and the multidisciplinary, preclinical HIM program can be seen as efficient starting point to complement the biologic perspective of medical education with a social and humanistic perspective.

    Peer-assisted learning (PAL) has become a well-accepted teaching method within medical education. However, descriptions of on-ward PAL programmes are rare. We introduced a PAL programme with a focus on clinical competencies on internal medicine wards. To assess the effects of an on-ward PAL programme on self-assessed clinical competencies. A total of 168 medical students were randomly assigned to one of the seven intervention wards or one of the seven control wards. During their 5-week ward-placement, the intervention group (IG; n = 88) received 10 patient-centred tutorials lead by final year tutors: (I) history taking, (II) physical examination, (III) blood withdrawal, (IV) infusion, (V) patient files, (VI and VII) ECG, (VIII-X) chart rounds. The control group (CG; n = 80) did not take part in the PAL programme. Clinical competencies were self-assessed pre- and post-intervention. For five of the ten assessed clinical competencies, increases in self-confidence ratings were significantly higher in the IG as compared to CG. RESULTS provide preliminary evidence to suggest that PAL programmes on internal medicine wards and with final year students as peer tutors may represent a valuable additional tool within medical clerkships. However, the findings must be confirmed and clarified in further research.

    Twenty years ago a radioisotope department was established in the old building of the 3rd Medical Clinic in Prague 2. The department is suitably placed and meets present requirements. It was set up as part of the 3rd Medical Clinic and of the Laboratory for endocrinology and Metabolism which gave it its main orientation and scope. Its present scope is much broader. In the twenty years since it was established 115,800 examinations were carried out, some 40 examination methods were introduced, 103 publications published, members of the department were co-authors of another 113 publications, they completed 11 research projects. The production of the department represents a substantial part of laboratory material especially in the diagnosis of endocrinopathy and metabolic disorders at the Clinic and is a significant part of the material of a number of research projects. The department has significantly contributed to the development of nuclear medicine in the Czechoslovak Socialist Republic in thyroid diagnosis, by the first introduction of radioimmunoassay methods, by the introduction of certain other special examination and laboratory methods and is currently taking part in the fulfilment of tasks given by the zoning of nuclear medicine in health care in Czechoslovakia in general and in Prague in particular.

    Kyungpook National University School of Medicine has been implementing hybrid problem-based learning (PBL) since 1999. The aim of this study was to investigate the changes in the students' perceptions and satisfaction levels of hybrid PBL. The target period of our study was from 1999 to 2014, and target subjects were second-year medical students in Kyungpook National University School of Medicine. The survey was conducted at the end of semester. We had a focused interview with group leaders and some volunteer students. As for the scores regarding students' overall satisfaction with PBL, there was significant improvement in 2005 compared to 2002, but the scores decreased and no differences between the survey years noted after 2005. The students' preference ratio for the once a week PBL sessions, tutor presence, synchronization of contents, and arrangement of PBL sessions and related lectures was 60%-80%, 50%-90%, 52%-96%, and 78%-93%, respectively. In order to increase students' satisfaction with hybrid PBL and to improve the perception of it, firstly, it is necessary to arrange the date and the time of PBL sessions so that students can concentrate on PBL. Secondly, PBL cases should be selected and arranged to be well synchronized with the ongoing lectures. Finally, it is important to create a safe atmosphere so that students can engage actively in PBL sessions.

    To explore the reasons that doctors choose to leave UK medicine after their foundation year two posts. All four regions of Scotland. Foundation year two doctors (F2s) working throughout Scotland who were considering leaving UK medicine after foundation training were recruited on a volunteer basis. Maximum variation between participants was sought. Semistructured interviews were coded using template analysis. Six perspectives, described by Feldman and Ng, were used as the initial coding template. The codes were then configured to form a framework that explores the interplay of factors influencing Foundation Year 2 (F2) doctors' decisions to leave UK medicine. Seventeen participants were interviewed. Six perspectives were explored. Structural influences (countrywide and worldwide issues) included visas, economic and political considerations, structure of healthcare systems and availability of junior doctor jobs worldwide. Organisational influences (the National Health Service (NHS) and other healthcare providers) included staffing and compensation policies, the working environment and the learning environment. Occupational influences (specific to being a junior doctor) comprised the junior doctor contract, role and workload, pursuit of career interests and the structure of training. Work group influences (relationships with colleagues) included support at work, task interdependence and use of locums. Personal life influences consisted of work-life balance, and support in resolving work-life conflict. The underlying theme of 'taking a break' recurred through multiple narratives. F2s give reasons similar to those given by any professional considering a change in their job. However, working within the NHS as an F2 doctor brought specific challenges, such as a need to make a choice of specialty within the F2 year, exposure to workplace bullying and difficulties in raising concerns. Despite these challenges, most F2s did not view their decision to leave as a permanent job

    Modern chemistry, so alarming, so necessary, so ubiquitous, became a mature science in nineteenth-century Europe. As it developed, often from a lowly position in medicine or in industry, so chemists established themselves as professional men; but differently in different countries. In 1820...... chemistry was an autonomous science of great prestige but chemists had no corporate identity. It was 1840 before national chemical societies were first formed; and many countries lagged fifty years behind. Chemists are the largest of scientific groups; and in this book we observe the social history...... of chemistry in fifteen countries, ranging from the British Isles to Lithuania and Greece. There are regularities and similarities; and by describing how national chemical professions emerged under particular economic and social circumstances, the book contributes significantly to European history of science....

Normally, group meetings are required, which may be a problem for busy medical educators. Here, we compared a modified Angoff individual method to the conventional group method. Methods: Six clinical instructors were divided into two groups matched by teaching experience: modified Angoff individual method (three persons and conventional group method (three persons. The passing scores were set by using the Angoff theory. The groups set the scores individually and then met to determine the passing score. In the modified Angoff individual method, passing scores were judged by each instructor and the final passing score was adjusted by the concordance method and reliability index. Results: There were 94 fourth-year medical students who took the test. The mean (standard deviation test score was 65.35 (8.38, with a median of 64 (range 46–82. The three individual instructors took 45, 60, and 60 minutes to finish the task, while the group spent 90 minutes in discussion. The final passing score in the modified Angoff individual method was 52.18 (56.75 minus 4.57 or 52 versus 51 from the standard group method. There was not much difference in numbers of failed students by either method (four versus three. Conclusion: The modified Angoff individual method may be a feasible way to set a standard passing score with less time consumed and more independent rather than group work by instructors.

Objectives: The current research was conducted to screen first year medical students accepted for enrollment at Alexandria Faculty of Medicine to identify those with a high probability of having psychological distress before the start of academic courses as well as explore the sources of stress among them.Methods.A cross sectional survey of 779 high school graduates accepted for admission to Alexandria Faculty of medicine was conducted. Participants were approached on the days of obligatory pre-enrollment medical examination. The translated Arabic version of DASS 21 questionnaire was used to screen students for three negative emotional symptoms namely depression, anxiety and stress. Inquiry about age, sex, residency and type of high school was added. Results: More than a tenth of studied medical students (12.6% suffered from severe or profound stress and 29.1% of them had mild to moderate stress. Moreover, one fifth (20% of studied students were severely anxious and less than one third (29.3% had mild to moderate anxiety. Severe and profound depression was diagnosed among 14.3% of students whereas, 18.7% them were moderately depressed. No association was found between any of studied negative emotional symptoms and the students' educational background or their residency. Conclusion: Nearly half of the prospective medical students might have some sort of psychological distress before starting their study in the Faculty of Medicine. They should be investigated to verify diagnosis and start intervention to minimize its adverse effects on academic performance and advancement at the faculty. Stress management courses should be considered for all medical students. Keywords: Psychological distress, Prospective medical students, Adolescents' psychological

    Leadership and management training during pathology residency have been identified repeatedly by employers as insufficient. A 1-month rotation in clinical laboratory management (CLM) was created for third-year pathology residents. We report on our experience and assess the value of this rotation. The rotation was one-half observational and one-half active. The observational component involved being a member of department and laboratory service line leadership, both at the departmental and institutional level. Observational participation enabled learning of both the content and principles of leadership and management activities. The active half of the rotation was performance of a project intended to advance the strategic trajectory of the department and laboratory service line. In our program that matriculates 4 residents per year, 20 residents participated from April 2010 through December 2015. Their projects either activated a new priority area or helped propel an existing strategic priority forward. Of the 16 resident graduates who had obtained their first employment or a fellowship position, 9 responded to an assessment survey. The majority of respondents (5/9) felt that the rotation significantly contributed to their ability to compete for a fellowship or their first employment position. The top reported benefits of the rotation included people management; communication with staff, departmental, and institutional leadership; and involvement in department and institutional meetings and task groups. Our 5-year experience demonstrates both the successful principles by which the CLM rotation can be established and the high value of this rotation to residency graduates.

    Alcohol and tobacco are legal, easily available addictive substances. There are no universal criteria of safe alcohol consumption but some scientific studies have allowed for determination of consumption levels helpful in evaluation of the pattern of drinking and evoking readiness to limit the amount of consumed alcohol. The aim of the work was to evaluate and compare the knowledge of 6th year students of the Faculty of Medicine of the Medical University of Biatystok in the academic years 2011/12 and 2012/13 concerning the effects of alcohol abuse, as well as to determine their drinking patterns and tobacco smoking structure. The study material was collected by means of anonymous voluntary surveys carried out before classes concerning the issues of addictions within the framework of family medicine subject block. 356 students took part in the study: 226 (63.5%) women and 130 (36.5%) men (palcohol abuse; 63.43% had an average level of knowledge and 31.71% - a low one. 51,32% women and 62,3% men drank alcohol in a hazardous way. A relation was found between a low level of knowledge and the amount of alcohol consumed on a typical drinking day (rS=-0.15, p=0.03) as well as between a low level of knowledge and hazardous drinking (rS=-0.13, p=0.03). Among the respondents, 18,58% women and 14,63% men smoked cigarettes regularly. Those who are 6th year students in the academic year 2012/13 usually had started smoking within the first three years of study at the Medical University and drank greater amounts of alcohol on a typical drinking day than students surveyed in the 2011/12 year. A correlation was found between tobacco smoking and a greater frequency of getting drunk occasionally (rS=-0.18, p=0.002) among students of both years. Insufficient knowledge on the effects of alcohol abuse and smoking coexist with a higher risk of drinking alcohol.

    The most common types of skin cancer found worldwide are basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. In America, about 800,000 people suffer from skin cancer every year and 75% are basal cell carcinoma. According to WHO, around 160,000 people suffer from malignant melanoma every year and 48,000 deaths were reported every year. In Jakarta, in 2000-2009, dr. CiptoMangunkusumo Hospital (RSCM) reported 261 cases of basal cell carcinoma, followed by 69 cases of squamous cell carcinoma and 22 cases of malignant melanoma.This study was descriptive study with retrospective design and consecutive sampling method. Data consisted of age, gender, tumor location, occupation and histopathology subtype which were taken from skin cancer patients’ medical record at Faculty of Medicine University of North Sumatera Pathology Anatomy Laboratory and Haji Adam Malik General Hospital Medan in 2012-2015. Data were analyzed using SPSS program and classified based on WHO. From 92 study subjects, squamous cell carcinoma is the most common form of skin cancer which is 59 cases (64.13%), found in 48 women (52.2%), and often found between 45-47 years old (30.4%).

    The purpose of incorporating humanities teaching into medical education is to encourage students to develop into more sensitive and caring doctors who communicate well with their patients and colleagues. A unique 4th year student elective at the Medical College of Wisconsin incorporates reflective and writing activities. Small group sessions are facilitated by faculty with specific interest and expertise in the humanities. Students keep a journal in which they record their reflections on personal issues, career planning and reactions to classroom discussions. Each student writes a poem and an essay or short story. The course is well received and oversubscribed. Students increase their understanding of the humanities through readings, small group discussions, journal keeping and formal writing. By incorporating humanism into their professional lives, medical students can learn to care for their patients in a more humane and thoughtful manner.

    The issue of medical error is relatively often discussed at forensic congresses or conferences. The authors carried out a medico-legal analysis of records of proceedings related to the appraisal of medical procedures investigated in the Forensic Medicine Department, Medical University of Silesia, Katowice, in the years 2000-2005. In 88 cases, where expert teams from the Department recognized medical errors to have been committed, 90% of such errors were demonstrated to have occurred on weekends and holidays. The majority of errors were associated with the decision-making process or diagnostic management and committed in hospital admission rooms or the so-called operative departments (orthopedic surgery, general surgery, gynecology, obstetrics). Evaluating the above presented cases, the authors drew attention to factors affecting the risk of medical error and the most common causes of inappropriate patient management.

    Violence against women is one of the most important health problems in recent times. In Mexico, it is reported a prevalence of 21.5% during pregnancy; however, it seems to be underdiagnosed. The objective is to determine the prevalence of domestic violence in pregnant women from 20 to 35 years at the Unidad de Medicina Familiar (UMF) 171 of the Instituto Mexicano del Seguro Social (IMSS). It was performed a cross-sectional descriptive study with a sample of 102 pregnant women to which we applied a sociodemographic questionnaire and the Severity of Violence Against Women Scale (ISVP). 19 women (18.6%) suffered violence; of these, 10.8% (n=11) experienced physical violence, 5.9% (n=6) psychological violence, and 4% (n=4) sexual violence. We used chi squared between the variable violence and each of the sociodemographic factors: 52.6% women (n=10) were married (p=0.005), 26.3% (n=5) had a bachelor's degree (p=0.074), 57.8% (n=11) had planned their pregnancy, 47.3% (n=9) were in the third trimester of pregnancy, and 78.95% (n=15) worked as laborers, shop-keepers or professionals (p=0.016). Among pregnant women belonging in UMF 171 of IMSS, domestic violence is a problem with a prevalence of 18.6%.

    The medical profession has traditionally been dominated by middle-class white males in the UK, but it is a political priority to widen access to all socio-economic and ethnic groups. This paper describes an empirical study based on biographical life narrative interviews with 45 16-year olds from inner London who were considering applying to medical school, drawn mainly from the most socio-economically deprived 25% of the population. Most of them were immigrants or the children of immigrants, and all had been selected by their teachers as highly able and motivated. Students were asked to "tell the story of your life so far". Interviews were tape recorded, transcribed and analysed thematically. Five influences on the development of academic identity and medical ambition were identified: (1) the private sphere (Bourdieu's 'family habitus'), especially a family meta-narrative of immigration to secure a better future and of education as the vehicle to regaining a high social position previously held in the family of origin; (2) the school (Bourdieu's 'institutional habitus'), and especially the input of particular teachers who inspired and supported the student; (3) friends and peers, many of whom the student had chosen strategically because of shared aspirations to academic success; (4) psychological resources such as maturity, determination and resilience; and (5) past experiences (especially meeting the challenge of immigration, changing school, or dealing with illness or death in a relative), which had proved formative and strengthening to the individual's developing ego. Despite their talents and ambitions, many students had important gaps in their knowledge of the application process and lacked sophistication in the 'admissions game'. The findings are discussed in relation to contemporary educational and social theories.

    To investigate the baseline level of knowledge of evidence based medicine (EBM) concepts in a sample of French medical students in their sixth year of training. An "electronic-questionnaire" was proposed to 3125 sixth-year students from all 39 French medical schools in 2009. Overall, 1870 students (58.2% response rate) completed the questionnaire (women=1168; 63%). The concept of EBM was known by 1716 students (92%). Most students (n=1382; 74%) read at least one French medical article per year, but 1051 students (56%) never read international articles. Just over half of students (1030; 55%) knew of web-based medical information databases. Treatment guidelines were considered to be important by most students (97%). Only 24.3% and 29% of students said that they write or speak English. In multivariate analysis, studying in a Parisian University and/or knowledge of what a journal's "impact factor" is were both associated with a ranking in the top 20% of the National Ranking Exam practice session. Only the most successful students showed interest in obtaining more knowledge of EBM. The lack of education about EBM in this sample suggests a lack of efficacy in the current heterogeneous EBM teaching programs. Copyright 2010 Elsevier Masson SAS. All rights reserved.

    Background: Patients with multiple sclerosis (MS) newly seen by a neurologist may benefit from early psychological intervention owing to the reciprocal relationship between stress and disease progression. However, it is uncertain what factors contribute to patients' receiving these services. Methods: Logistic regression analysis of prospectively gathered data evaluated how demographic and disease characteristics and emotional/physical health factors contributed to referral to receive behavioral medicine (BM) services within 1 year of their first neurology appointment at the Mellen Center for Multiple Sclerosis at the Cleveland Clinic. Survival analyses then evaluated whether this resulted in earlier receipt of services. Results: Although many factors were associated with receiving BM services during univariate analyses (age, race, marital status, years since MS onset, depression, stress, and quality of life), when considering multivariable interactions, only two variables remained significant: age (odds ratio [OR] = 0.86, 95% confidence interval [CI], 0.80–0.92) and depression (OR = 1.56, 95% CI, 1.39–1.75). Survival analyses did not show differences in time to BM services for stratifications of age or depression scores. Conclusions: Younger patients and patients with more severe depression were more likely to receive BM services within 1 year of their first neurology appointment. Future research will focus on evaluating whether these are also the patients in greatest need of services or whether they are simply more open to receiving them. PMID:28835744

    In recent years, the number of articles in The American Journal of Sports Medicine (AJSM) has risen dramatically, with an increasing emphasis on evidence-based medicine in orthopaedics and sports medicine. Despite the increase in the number of articles published in AJSM over the past decade, the methodological quality of articles in 2011-2013 has improved relative to those in 2001-2003 and 1991-1993. Meta-analysis. All articles published in AJSM during 2011-2013 were reviewed and classified by study design. For each article, the use of pertinent methodologies, such as prospective data collection, randomization, control groups, and blinding, was recorded. The frequency of each article type and the use of evidence-based techniques were compared relative to 1991-1993 and 2001-2003 by use of Pearson χ(2) testing. The number of research articles published in AJSM more than doubled from 402 in 1991-1993 and 423 in 2001-2003 to 953 in 2011-2013. Case reports decreased from 15.2% to 10.6% to 2.1% of articles published over the study period (P < .001). Cadaveric/human studies and meta-analysis/literature review studies increased from 5.7% to 7.1% to 12.4% (P < .001) and from 0.2% to 0.9% to 2.3% (P = .01), respectively. Randomized, prospective clinical trials increased from 2.7% to 5.9% to 7.4% (P = .007). Fewer studies used retrospective compared with prospective data collection (P < .001). More studies tested an explicit hypothesis (P < .001) and used controls (P < .001), randomization (P < .001), and blinding of those assessing outcomes (P < .001). Multi-investigator trials increased (P < .001), as did the proportion of articles citing a funding source (P < .001). Despite a dramatic increase in the number of published articles, the research published in AJSM shifted toward more prospective, randomized, controlled, and blinded designs during 2011-2013 compared with 2001-2003 and 1991-1993, demonstrating a continued improvement in methodological quality. © 2015 The

    Full Text Available Social media applications and their use among students have witnessed dramatic increase in the last decade and data on their effect on students academic performance are inconsistent. The aim of this study was to assess the impact of social media on the academic performance and grades of second year medical students at the College of Medicine, University of Babylon, Iraq. Second year medical students (n=57 completed online questionnaire about the type of social media they use frequently, time spent on these media in hours per day, the reasons for use of these media and the effect of social media on their grades. Students were also asked to provide the cumulative grades of physiology and anatomy courses. Time spent by students on social media and facebook messenger was correlated with combined grades of physiology and anatomy courses. All students have been using facebook and 96.5% have been using facebook messenger. Other popular applications were telegram, instagram and ask.fm. Average time spent on social media was 5.07+/- 2.93 and on facebook messenger was 1.80 +/-1.45 hours per day. Forty-two percent of students reported that social media have positive effect on their academic performance. No correlation has been found between time spent on social media or facebook messenger and students combined grades of physiology and anatomy. To conclude, social media and in particular facebook and facebook messenger are very popular among second year medical students. Time spent on social media seems to have no influence on second year medical students grades and academic performance. [J Med Allied Sci 2016; 6(2.000: 77-83

    We describe a specific mentoring approach in an academic general internal medicine setting by audiotaping and transcribing all mentoring sessions in the year. In advance, the mentor recorded his model. During the year, the mentee kept a process journal. Qualitative analysis revealed development of an intimate relationship based on empathy, trust, and honesty. The mentor's model was explicitly intended to develop independence, initiative, improved thinking, skills, and self-reflection. The mentor's methods included extensive and varied use of questioning, active listening, standard setting, and frequent feedback. During the mentoring, the mentee evolved as a teacher, enhanced the creativity in his teaching, and matured as a person. Specific accomplishments included a national workshop on professional writing, an innovative approach to inpatient attending, a new teaching skills curriculum for a residency program, and this study. A mentoring model stressing safety, intimacy, honesty, setting of high standards, praxis, and detailed planning and feedback was associated with mentee excitement, personal and professional growth and development, concrete accomplishments, and a commitment to teaching.

    To determine the effect of instructor attitude, enthusiasm, and teaching style on learning for distance and campus pharmacy students. Over a 3-year period, distance and campus students enrolled in the spring semester of a medicinal chemistry course were asked to complete a survey instrument with questions related to instructor attitude, enthusiasm, and teaching style, as well as items to measure student intrinsic motivation and vitality. More positive responses were observed among distance students and older students. Gender did not impact student perspectives on 25 of the 26 survey questions. Student-related items were significantly correlated with instructor-related items. Also, student-related items and second-year cumulative grade point average were predictive of students' final course grades. Instructor enthusiasm demonstrated the highest correlation with student intrinsic motivation and vitality. While this study addresses the importance of content mastery and instructional methodologies, it focuses on issues related to instructor attitude, instructor enthusiasm, and teaching style, which all play a critical role in the learning process. Thus, instructors have a responsibility to evaluate, reevaluate, and analyze the above factors to address any related issues that impact the learning process, including their influence on professional students' intrinsic motivation and vitality, and ability to meet educational outcomes.

    Full Text Available Background. A Required Fourth-Year Medical Student Physical Medicine and Rehabilitation (PM&R Clerkship was found to increase students’ knowledge of PM&R; however the students’ overall rotation evaluations were consistently lower than the other 8 required clerkships at the medical school. Objective. To describe the impact of a revised curriculum based upon Entrustable Professional Activities and focusing on basic pain management, musculoskeletal care, and neurology. Setting. Academic Medical Center. Participants. 73 fourth-year medical students. Methods. The curriculum changes included a shift in the required readings from rehabilitation specific topics toward more general content in the areas of clinical neurology and musculoskeletal care. Hands-on workshops on neurological and musculoskeletal physical examination techniques, small group case-based learning, an anatomy clinical correlation lecture, and a lecture on pain management were integrated into the curriculum. Main Outcome Measurements. Student evaluations of the clerkship. Results. Statistically significant improvements were found in the students’ evaluations of usefulness of lecturers, development of patient interviewing skills, and diagnostic and patient management skills (p≤0.05. Conclusions. This study suggests that students have a greater satisfaction with a required PM&R clerkship when lecturers utilize a variety of pedagogic methods to teach basic pain, neurology and musculoskeletal care skills in the rehabilitation setting rather than rehabilitation specific content.

    Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

    Fifty-nine acupoints for febrile disease is recorded in Huangdi Neijing ( Huangdi's Internal Classics ). By analyzing the combination of these acupoints, the writer discovered the acupoint composition and detected their origins from Huangdi's Internal Classics , in which the terms biaoben, qijie and beishu are involved in the theoretic evidence. The writer thought the "fifty-nine acupoints for febrile disease" implied the self-evolution of some acupuncture school in ancient time, which was formed by absorbing the theoretic experiences of the other schools. It is necessary to analyze and interpret the other literatures besides Huangdi's Internal Classics and probably obtain the further reorganization on it.

    No prior study has empirically characterized the association between health risks and reading popular fiction depicting violence against women. Fifty Shades--a blockbuster fiction series--depicts pervasive violence against women, perpetuating a broader social narrative that normalizes these types of risks and behaviors in women's lives. The present study characterized the association between health risks in women who read and did not read Fifty Shades; while our cross-sectional study design precluded causal determinations, an empirical representation of the health risks in women consuming the problematic messages in Fifty Shades is made. Females ages 18 to 24 (n=715), who were enrolled in a large Midwestern university, completed a cross-sectional online survey about their health behaviors and Fifty Shades' readership. The analysis included 655 females (219 who read at least the first Fifty Shades novel and 436 who did not read any part of Fifty Shades). Age- and race-adjusted multivariable models characterized Fifty Shades' readers and nonreaders on intimate partner violence victimization (experiencing physical, sexual and psychological abuse, including cyber-abuse, at some point during their lifetime); binge drinking (consuming five or more alcoholic beverages on six or more days in the last month); sexual practices (having five or more intercourse partners and/or one or more anal sex partner during their lifetime); and using diet aids or fasting for 24 or more hours at some point during their lifetime. One-third of subjects read Fifty Shades (18.6%, or 122/655, read all three novels, and 14.8%, or 97/655, read at least the first novel but not all three). In age- and race-adjusted models, compared with nonreaders, females who read at least the first novel (but not all three) were more likely than nonreaders to have had, during their lifetime, a partner who shouted, yelled, or swore at them (relative risk [RR]=1.25) and who delivered unwanted calls/text messages

    In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, although it focuses only on NM exams for the years 2011 and 2012. The annual frequency of each of the 28 selected NM exams and the average administered activity per procedure was obtained by means of a nationwide survey sent to the 35 NM centres in Portugal. The results show a reduction of the number of cardiac exams performed in the last two years compared with 2010, leading to a reduction of the annual average effective dose of Portuguese population due to NM exams from 0.08 mSv ± 0.017 mSv/caput to 0.059 ± 0.011 mSv/caput in 2011 and 0.054 ± 0.011 mSv/caput in 2012. Portuguese total annual average collective effective dose due to medical procedures was estimated to be 625.6 ± 110.9 manSv in 2011 and 565.1 ± 117.3 manSv in 2012, a reduction in comparison with 2010 (840.3 ± 183.8 manSv). The most frequent exams and the ones that contributed the most for total population dose were the cardiac and bone exams, although a decrease observed in 2011 and in 2012 was verified. The authors intend to perform this study periodically to identify trends in the annual Portuguese average effective dose and to help to raise awareness about the potential dose optimization.

This paper presents the results of a national survey on the contents, methods and framework of GTE teaching. Methods: Semi-structured questionnaire dispatched in July 2014 to 38 institutions responsible for GTE teaching. Descriptive analysis of quantitative data and content analysis of free-text answers. Results: It was possible to collect data from 29 institutes responsible for GTE teaching (response: 76%). There is at least one professorial chair for GTE in 19 faculties; two professorial chairs or professorships remained vacant at the time of the survey. The number of students taught per academic year ranges from 350. Teaching in GTE comprises an average of 2.18 hours per week per semester (min: 1, max: 6). Teaching in GTE is proportionally distributed according to an arithmetic average as follows: history: 35.4%, theory 14.7% and ethics 49.9%. Written learning objectives were formulated for GTE in 24 faculties. The preferred themes of teaching in history, theory or ethics which according to respondents should be taught comprise a broad spectrum and vary. Teaching in ethics (79 from a max. of 81 possible points) is, when compared to history (61/81) and theory (53/81), attributed the most significance for the training of medical doctors. Conclusion: 10 years after the introduction of GTE the number of students and the personnel resources available at the institutions vary considerably. In light of the differences regarding the content elicited in this study the pros and cons of heterogeneity in GTE should be discussed.

    Purpose: Flood-field uniformity evaluation is an essential element in the assessment of nuclear medicine (NM) gamma cameras. It serves as the central element of the quality control (QC) program, acquired and analyzed on a daily basis prior to clinical imaging. Uniformity images are traditionally analyzed using pixel value-based metrics which often fail to capture subtle structure and patterns caused by changes in gamma camera performance requiring additional visual inspection which is subjective and time demanding. The goal of this project was to develop and implement a robust QC metrology for NM that is effective in identifying non-uniformity issues, reporting issues in a timely manner for efficient correction prior to clinical involvement, all incorporated into an automated effortless workflow, and to characterize the program over a two year period. Methods: A new quantitative uniformity analysis metric was developed based on 2D noise power spectrum metrology and confirmed based on expert observer visual analysis. The metric, termed Structured Noise Index (SNI) was then integrated into an automated program to analyze, archive, and report on daily NM QC uniformity images. The effectiveness of the program was evaluated over a period of 2 years. Results: The SNI metric successfully identified visually apparent non-uniformities overlooked by the pixel valuebased analysis methods. Implementation of the program has resulted in nonuniformity identification in about 12% of daily flood images. In addition, due to the vigilance of staff response, the percentage of days exceeding trigger value shows a decline over time. Conclusion: The SNI provides a robust quantification of the NM performance of gamma camera uniformity. It operates seamlessly across a fleet of multiple camera models. The automated process provides effective workflow within the NM spectra between physicist, technologist, and clinical engineer. The reliability of this process has made it the preferred

    The book presents a number of fundamental imaging principles in nuclear medicine. The fact that low radiation doses are sufficient for the study of normal and changed physiological functions of the body is an important advancement brought about by nuclear medicine. The possibility of quantitative investigations of organs and organ regions and of an assessment of their function as compared to normal values is a fascinating new diagnostic dimension. The possibility of comparing the findings with other pathological findings and of course control in the same patient lead to a dynamic continuity with many research possibilities not even recognized until now. The limits of nuclear scanning methods are presented by the imprecise structural information of the images. When scintiscans are compared with X-ray images or contrast angiography, the great difference in the imaging of anatomical details is clearly seen. But although the present pictures are not optimal, they are a great improvement on the pictures that were considered clinically valuable a few years ago. (orig./AJ) [de

Department of Community Medicine at Fatima Memorial College of Medicine and Dentistry from July to November 2010. A probability technique of simple random sampling was used to collect 63 students from the third and fourth year MBBS who were randomly distributed in five sub-groups. They were variously ascribed the roles of obsceners, participants and helpers. A questionnaire was distributed to collect student's responses. The data was analyzed on SPSS version 17 to compare the responses. Chi-square test was applied and p-value was fixed at students were selected as participants of this study in which 46 belonged to the fourth year MBBS class (73%) and 17 were third year MBBS students (27%). There were 13 male (20.6%) and 50 female (79.4%) students. Role-plays were identified as most effective method of teaching (n = 25, 37.9%) followed by lectures (n = 17, 25.8%, p = 0.054). Fifty-two students (78.5%) admitted that role-plays improved their knowledge of the subject, 55 (84.6%) said that it will help them in their clinical performance. Fifty-nine participants (89.4%) found role-plays interesting and 49 (74.2%) wanted to incorporate role-plays as a part of curriculum. Fifty-six of the participants (88.9%) agreed that role-plays improved their communication skills. Twenty-one participants (31.8%) believed that it helped them in making acquaintance with the local situation. Forty-six students (76.7%) identified role-plays as a feasible way of andragogy (p = 0.005) and 48 (76.2%) said that it provoked critical thinking about the subject (p = 0.038). Fifty-four students (85.7%) admitted that their attention span was better in role-plays as compared to lectures (p = 0.047). Role-plays were well accepted by the students as an effective teaching methodology and can be incorporated as a part of teaching strategies in Community Medicine.

    Although the practice of western medicine in Ethiopia dates back to the time of King Libne Dengel (1520-1535), organized and sustainable modern medical practice started after the battle of Adwa (1896). To review hospitals construction, medical doctors production and attrition, and to suggest alternative medical doctors retention mechanisms in the public sector and production scale up options. In this article, 100 years Ethiopian modern medical history is revised from old and recent medical chronicles. Until December 2006 primary data was collected from 87 public hospitals. Much emphasis is given to medical doctors profile (1906-2006), hospitals profile (1906-2005), medical doctors to population and hospitals ratio (1965-2006), Ethiopian public medical schools 42 years attainment (1964-2006), annual attrition rate (1984-2006), organizational structure of medical faculties & university hospitals, medical doctors remuneration by the Ministry of Health (MOH), Ministry of Education (MOE), NGOs and private health institutions. This article also addresses the way forward from physician training and retention perspectives, multiple alternate mechanisms to increase physicians' motivation to work in government institutions and reveres the loss. Medical doctors production scale up option is also given much emphasis. Most data are presented using line and bar graphs. Literature review showed that the first three hospitals were constructed in 1896 (Russian hospital), 1903 (Harar Ras Mekonnen hospital) and 1906 (Menelik II hospital). In 2005, 139 hospitals (87 public and 52 others) were reported. Remarkable hospital construction was done between 1935 and 1948, and recently between 1995 and 2005; however, in the latter case, private hospitals construction took the lions share. By the time MOH was established (1948), 110 Ethiopian and expatriate medical doctors were working, mainly in the capital, and 46 hospitals constructed. Physician number increment was very slow till 1980 at

    Expedition and wildeness medicine is a term that combines rescue medicine, sport medicine as well as more specific branches as polar or high altitude medicine. It is being intensively studied both at the reaserch institutes and on expeditions. Ophtalmologists are concentrated on the reaserch of HARH (High Altitude Retinal Hemorrhage), neurologists on HACE reaserch (High Altitude Cerebral Edema), psychologists are developing tests to decsribe cognitive functions and many physicians are being trained to work in extreme enviroment. The result of all this effort are numerous new findings in pathophysiology and therapy of altitude illness, increased security on expedition and further development of expeditionism.

    Nuclear Medicine is a medical specialty that uses radionuclides for the diagnosis and treatment of diseases and it is one of the most important peaceful applications of nuclear sciences. Nuclear Medicine has a short history both in Turkey and in the world. The first use of I-131 for the treatment of thyrotoxicosis in Turkey was in 1958 at the Istanbul University Cerrahpasa Medical School. In 1962, Radiobiological Institute in Ankara University Medical School was established equipped with well-type counters, radiometers, scalers, external counters and a rectilinear scanner. In 1965, multi-probe external detection systems, color dot scanners and in 1967, anger scintillation camera had arrived. In 1962, wet lab procedures and organ scanning, in 1965 color dot scanning, dynamic studies (blood flow - renograms) and in 1967 analogue scintillation camera and dynamic camera studies have started. In 1974, nuclear medicine was established as independent medical specialty. Nuclear medicine departments have started to get established in 1978. In 1974, The Turkish Society of Nuclear Medicine (TSNM) was established with 10 members. The first president of TSNM was Prof. Dr. Yavuz Renda. Now, in the year 2000, TSNM has 349 members. Turkish Society of Nuclear Medicine is a member of European Association of Nuclear Medicine (EANM), World Federation of Nuclear Medicine and Biology (WFNMB) and WFNMB Asia-Oceania. Since 1974, TSNM has organized 13 national Nuclear Medicine congresses, 4 international Nuclear Oncology congresses and 13 nuclear medicine symposiums. In 1-5 October 2000, 'The VII th Asia and Oceania Congress of Nuclear Medicine and Biology' was held in Istanbul, Turkey. Since 1992, Turkish Journal of Nuclear Medicine is published quarterly and it is the official publication of TSNM. There are a total of 112 Nuclear Medicine centers in Turkey. There are 146 gamma cameras. (52 Siemens, 35 GE, 16 Elscint, 14 Toshiba, 10 Sopha, 12 MIE, 8 Philips, 9 Others) Two cyclotrons are

    With a history going back approximately 2,500 years, the Tibetan medicine, known as Sowa Rigpa in the Tibetan language, is one of the world's oldest known traditional medicine. It originally developed during the pre-Buddhist era in the kingdom known as Shang Shung. As a traditional medicine, the future development of Tibetan medicine in Western countries is linked to being recognized as a popular and viable healthcare option providing an alternative clinical reality. Its inherent ability to incorparate predictive diagnostics, targeted prevention, and the creation of individualized medical treatment give Tibetan medicine great potential for assessing and treating patients.

    Can vitamin D deficiency be predicted by patient questionnaire? Does it lead to secondary hyperparathyroidism that may cause excessive bone resorption? We studied non-osteoporotic subjects in their fifties, in whom vitamin D levels are often tested. Patients hospitalised for degenerative osteoarthritis or consulting for assessment of menopause, without renal failure and not treated with vitamin D, completed a questionnaire on sun exposure and underwent measurement of serum calcium, creatinine, 25OH vitamin D, PTH and CTX. Five hundred and twenty-six subjects, mean age 54.6 years (71% women), were investigated throughout the year. 25OH vitamin D levels were correlated with sun exposure and varied according to the month of the year, unlike PTH and CTX levels. From November to May, over 90% of subjects had 25OH vitamin D levelssecondary hyperparathyroidism, characterised by serum calcium65pg/mL, associated with increased CTX levels. Vitamin D deficiency can be predicted by patient questionnaire. It very rarely leads to secondary hyperparathyroidism. Copyright © 2015. Published by Elsevier Masson SAS.

    Full Text Available BACKGROUND Obstetric assistance made major advances in the last 20 years: improved surgical technique allows quicker caesarean sections, anaesthesiology procedures such as peripheral anaesthesia and epidural analgesia made safer operative assistance, remarkably reducing perioperative morbidity and mortality, neonatology greatly improved the results of assistance to low birth weight newborns. A new branch of medicine called “obstetric medicine” gained interest and experience after the lessons of distinguished physicians like Michael De Swiet in England. All together these advances are making successful pregnancies that 20 years ago would have been discouraged or even interrupted: that’s what we call high risk pregnancy. High risk of what? Either complications of pregnancy on pre-existing disease or complications of pre-existing disease on pregnancy. Nowadays, mortality in pregnancy has a medical cause in 80% of cases in Western countries (Confidential Enquiry on Maternal Deaths, UK, 2004. DISCUSSION The background is always changing and we have to take in account of: increase of maternal age; widespread use of assisted fertilization techniques for treatment of infertility; social feelings about maternity desire with increasing expectations from medical assistance; immigration of medically “naive” patients who don’t know to have a chronic disease, but apt and ready to conceive; limited knowledge of feasibility of drug use in pregnancy which may induce both patients and doctors to stopping appropriate drug therapy in condition of severe disease. Preconception counseling, planning the pregnancy, wise use of drugs, regular follow-up throughout the pregnancy and, in selected cases, preterm elective termination of pregnancy may result in excellent outcome both for mother and foetus. CONCLUSIONS Highly committed and specifically trained physicians are required to counsel these patients and to plan their treatment before and during pregnancy.
